Fundamentals Description Field

[0002] The present description, for example, relates to wireless communication systems, and more particularly to techniques for transmitting uplink control channels over an unlicensed radio frequency spectrum band. Description of Related Technique

[0003] Wireless communication systems are widely developed to provide various types of communication content such as voice, video, packet data, messaging, broadcasting and so on. These systems may be multiple access systems capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and energy). Examples of such multiple access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, and frequency division multiple access (FDMA) systems. orthogonal frequency division (OFDMA).

[0004] By way of example, a wireless multiple access communication system may include multiple base stations, each simultaneously supporting communication for multiple communication devices, otherwise known as user equipment (UEs). A base station can communicate with UEs on downlink channels (e.g., for transmissions from a base station to a UE) and uplink channels (e.g., for transmissions from a UE to a base station).

[0005] Some communication modes may allow communications with a UE over an unlicensed radio frequency spectrum band, or across different radio frequency spectrum bands (e.g., a radio frequency spectrum band licensed and/or an unlicensed radio frequency spectrum band) of a cellular network. With increasing data traffic in cellular networks utilizing a licensed radio frequency spectrum band, offloading at least part of the data traffic to an unlicensed radio frequency spectrum band may provide a cellular operator with the opportunities to improve data transmission capacity. In some cases, an uplink control channel may be transmitted over an unlicensed radio frequency spectrum band. Efficient transmission of such an uplink control channel and/or coordination of uplink control channel transmissions from multiple UEs may be desirable.

In some examples, a plurality of UEs may have uplink control information (e.g., acknowledgment information and/or channel state information) to transmit to a base station at the same time. However, the resources available for transmitting uplink control information from different UEs may be finite. The described techniques, therefore, allow for the efficient and/or flexible allocation and sharing of a finite number of resources among a plurality of UEs, and allow for the provision of a greater or lesser part of the resources to one or more UEs.

Detailed Description

[0079] Techniques are described in which an unlicensed radio frequency spectrum band is used for at least a portion of communication via a wireless communication system. In some examples, the unlicensed radio frequency spectrum band may be used for Long Term Evolution (LTE) communications and/or LTE-Advanced (LTE-A) communications. The unlicensed radio frequency spectrum band may be used in combination with, or independently of, a licensed radio frequency spectrum band. In some examples, the unlicensed radio frequency spectrum band may be a radio frequency spectrum band to which a device may need to compete for access since the radio frequency spectrum band is available, at least in part, for unlicensed use, such as Wi-Fi use.

[0080] With increasing data traffic in cellular networks utilizing a licensed radio frequency spectrum band, offloading at least part of the data traffic to an unlicensed radio frequency spectrum band may provide an operator with cellular (e.g., an operator of a public land mobile network (PLMN) and/or a coordinated set of base stations defining a cellular network, such as an LTE/LTE-A network) opportunities to improve data transmission capacity. As noted above, prior to communicating over the unlicensed radio frequency spectrum band, devices may perform a listen-before-talk (LBT) procedure to gain access to the medium. Such an LBT procedure may include performing a released channel assessment (CCA) procedure (or extended CCA procedure) to determine whether a channel from the unlicensed radio frequency spectrum band is available. When it is determined that a channel is not available, a CCA procedure (or extended CCA procedure) may be performed for the channel again at a later time.

[0081] The use of an unlicensed radio frequency spectrum band for wireless communication may present situations in which an uplink control channel is transmitted through the unlicensed radio frequency spectrum band. The uplink control channel may include uplink control information such as notices of receipt and/or notices of non-receipt of downlink transmissions, and/or channel state information for the unlicensed radio frequency spectrum band. When a plurality of UEs can have uplink control information to transmit at the same time, managing the resources available for transmitting uplink control channels from UEs to a base station may be desirable, so that all UEs can transmit uplink control information at the same time and/or some or all of the UEs may utilize a greater or lesser part of the resources.

[0082] The following description provides examples, and is not limiting the scope, applicability or examples presented in the claims. Changes can be made to the function and arrangement of the elements discussed without straying from the scope of the description. Various examples may omit, replace, or add various procedures or components as appropriate. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined in other examples.

[0083] Figure 1 illustrates an example of a wireless communication system 100, in accordance with various aspects of the description. The wireless communication system 100 may include base stations 105, UEs 115 and a core network 130. The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, targeting, or mobility functions. The base stations 105 may interface with the core network 130 via return access channel links 132 (e.g., S1, etc.) and may perform radio configuration and programming for communication with the UEs 115, or may operate under the control of a base station controller (not illustrated). In various examples, base stations 105 may communicate, directly or indirectly (e.g., via core network 130), with each other via return access channel links 134 (e.g., X1, etc., which may be wired or wireless communication links.

[0084] The base stations 105 may communicate wirelessly with the UEs 115 via one or more base station antennas. Each of the base stations 105 may provide communications coverage for a respective geographic coverage area 110. In some examples, a base station 105 may be referred to as a base transceiver station, a radio base station, an access point, a radio transceiver, a Node B, an eNodeB (eNB), a home Node B, a home eNodeB, or some other suitable terminology. The geographic coverage area 110 for a base station 105 may be divided into sectors creating a portion of the coverage area (not illustrated). The wireless communication system 100 may include base stations 105 of different types (e.g., macro cellular base stations and/or small cellular base stations). There may be overlapping geographic coverage areas 110 for different technologies.

[0085] In some examples, the wireless communication system 100 may include an LTE/LTE-A network. In LTE/LTE-A networks, the term enhanced or evolved Node B (eNB) may be generally used to describe the base stations 105, while the term UE may be generally used to describe the UEs 115. The wireless communication system 100 It can be a Heterogeneous LTE/LTE-A network in which different types of eNBs provide coverage for various geographic regions. For example, each eNB or base station 105 may provide communications coverage for a macro cell, a small cell, and/or other cell types. The term "cell" is a 3GPP term that may be used to describe a base station, a carrier or component carrier associated with a base station, or a coverage area (e.g. sector, etc.) of a carrier or station basis, depending on the context.

[0086] A macro cell may generally cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions with the network provider. A small cell can be a low-powered base station, compared to a macro cell which can operate in the same or different radio frequency spectrum bands as macro cells. Small cells may include pico cells, femto cells and micro cells according to various examples. A pico cell can cover a relatively smaller geographic area and can allow unrestricted access by UEs with service subscriptions with the network provider. A femto cell may also cover a relatively small geographic area (e.g., a residence) and may provide access restricted by UEs possessing an association with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs for users at home and similar). An eNB for a macro cell can be referred to as a macro eNB. An eNB for a small cell may be referred to as a small cell eNB, a pico eNB, a femto eNB, or a home eNB. An eNB may support one or multiple (e.g., two, three, four, and the like) cells (e.g., component carriers).

[0087] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, base stations can have similar frame timing, and transmissions from different base stations can be approximately aligned in time. For asynchronous operation, base stations may have different frame timings, and transmissions from different base stations may not be aligned in time. The techniques described here can be used for synchronized or asynchronous operations.

[0088] Communication networks that can accommodate some of the various examples described can be packet-based networks that operate according to a layered protocol stack. At the user plane, communications at the Packet Data Convergence Protocol (PDCP) support or layer can be IP-based. A Radio Link Control (RLC) layer can perform packet segmentation and reassembly to communicate over logical channels. A Medium Access Control (MAC) layer can perform priority handling and logical channel multiplexing on transport channels. The MAC layer can also use Hybrid Automatic Repeat Request (HARQ) to provide retransmission at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer may provide for the establishment, configuration and maintenance of an RRC connection between a UE 115 and the base stations 105 or core network 130 supporting the radio bearers for the user plan data. At the Physical layer (PHY), transport channels can be mapped into Physical channels.

[0089] The UEs 115 may be distributed throughout the wireless communication system 100, and each UE 115 may be stationary or mobile. A UE 115 may also include or may be referred to by those skilled in the art as a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device , a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, an apparatus, a user agent, a mobile client, a client , or some suitable terminology. A UE 115 may be a cellular telephone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet computer, a laptop computer, a cordless telephone, a circuit station wireless location (WLL) or similar. A UE may be capable of communicating with various types of base stations and network equipment, including macro eNBs, small cell eNBs, relay base stations, and the like.

[0090] The communication links 125 illustrated in the wireless communication system 100 may include downlink (DL) transmissions from a base station 105 to a UE 115, and/or uplink transmissions (UL) from a UE 115 to a station base 105. Downlink transmissions can also be called forward link transmissions, while uplink transmissions can also be called reverse link transmissions. In some examples, UL transmissions may include transmissions of uplink control information, which uplink control information may be transmitted over an uplink control channel (e.g., a physical uplink control channel (PUCCH) and/or or enhanced or evolved PUCCH (ePUCCH). Uplink control information may include, for example, notices of receipt and/or notices of non-receipt of downlink transmissions, and/or channel state information. UL transmissions may also UL transmissions may also include the transmission of a sound reference signal (SRS) , a physical random access channel (PRACH) and/or enhanced or evolved PRACH (ePRACH) (e.g., in a dual connectivity mode and/or independent mode described with reference to Figure 2), and/or scheduling request ( SR) and/or evolved or improved SR (eSR) (e.g., in the independent mode described with reference to Figure 2). In some examples, an eSR may have a one-bit payload. When channel mapping is employed, an eSR can span a symbol across the entire bandwidth of a component carrier, be transmitted on the same symbol as an eSRS, and be transmitted using an altered Zadoff-Chu (ZC) sequence, cyclical, interspersed with resource block. In some examples, an eSRS may have no payload at all. When channel mapping is employed, an eSRS can span a symbol across the entire bandwidth of a component carrier, be transmitted on the same symbol as an eSR, and be transmitted using an altered, cyclic, block-interleaved ZC sequence. resources.

[0091] In some examples, each communication link 125 may include one or more carriers, where each carrier may be a signal created from multiple subcarriers (e.g., waveform signals of different frequencies) modulated according to various radio technologies described above. Each modulated signal can be sent on a different subcarrier and can carry control information (e.g. reference signals, control channels, etc.), overhead information, user data, etc. Communication links 125 may transmit bidirectional communications utilizing a frequency domain duplexing (FDD) operation (e.g., utilizing unpaired spectrum resources). Frame structures for FDD operation (e.g., frame structure type 1) and TDD operation (e.g., frame structure type 2) can be defined.

[0092] In some embodiments of the wireless communication system 100, the base stations 105 and/or UEs 115 may include multiple antennas to employ antenna diversity schemes to improve communication quality and reliability between the base stations 105 and UEs 115. Additionally or alternatively, base stations 105 and/or UEs 115 may employ multiple input multiple output (MIMO) techniques that can take advantage of multipath environments to transmit multiple spatial layers carrying the same or different encoded data.

[0093] The wireless communication system 100 may support operation on multiple cells or carriers, a feature that may be referred to as a carrier aggregation (CA) or multiple carrier operation. A carrier may also be referred to as a component carrier (CC), a layer, a channel, etc. The terms "carrier", "component carrier", "cell" and "channel" may be used interchangeably here. A UE 115 may be configured with multiple downlink CCs and one or more uplink CCs for bearer aggregation. Carrier aggregation can be used with both FDD and TDD component carriers.

[0094] Figure 2 illustrates a wireless communication system 200 in which LTE/LTE-A can be deployed under different situations using an unlicensed radio frequency spectrum band, in accordance with various aspects of the present description. More specifically, Figure 2 illustrates examples of a supplemental downlink mode, a carrier aggregation mode, and an independent mode in which LTE/LTE-A is deployed using an unlicensed radio frequency spectrum band. The wireless communication system 200 may be an example of parts of the wireless communication system 100 described with reference to Figure 1. Furthermore, a first base station 205 and a second base station 206 may be examples of aspects of one or more of the base stations 105 described with reference to Figure 1, while a first UE 215, a second UE 216, a third UE 217 and a fourth UE 218 may be examples of aspects of one or more of the UEs 115 described with reference to Figure 1.

[0095] In the example of a supplemental downlink mode in wireless communication system 200, the first base station 205 may transmit orthogonal frequency division multiple access (OFDMA) waveforms to the first UE 215 using a downlink channel 220. Downlink channel 220 may be associated with an F1 frequency in an unlicensed radio frequency spectrum band. The first base station 205 may transmit OFDMA waveforms to the first UE 215 using a first bidirectional link 225 and may receive single-carrier frequency division multiple access (SC-FDMA) waveforms from the first UE 215 using the first bidirectional link 225. The first bidirectional link 225 may be associated with a frequency F4 in a licensed radio frequency spectrum band. The downlink channel 220 in the unlicensed radio frequency spectrum band and the first bidirectional link 225 in the licensed radio frequency spectrum band may operate simultaneously. Downlink channel 220 may provide an offload of downlink capacity to the first base station 205. In some examples, downlink channel 220 may be used for unicast services (e.g., addressed to a UE) and for multicast services. (e.g. addressed to multiple UEs). This situation can occur with any service provider (e.g. a mobile network operator (MNO)) that utilizes a licensed radio frequency spectrum and needs to alleviate some of the traffic and/or signaling congestion.

[0096] In an example of a carrier aggregation mode in wireless communication system 200, the first base station 205 may transmit OFDMA waveforms to the second UE 216 using a second bidirectional link 230 and may receive OFDMA waveforms , SC-FDMA waveforms and/or FDMA waveforms interleaved with resource block of the second UE 216 using the second bidirectional link 230. The second bidirectional link 230 may be associated with the frequency F1 in the radio frequency spectrum band unlicensed. The first base station 205 may also transmit OFDMA waveforms to the second UE 216 using a third bidirectional link 235 and may receive SC-FDMA waveforms from the second UE 216 using the third bidirectional link 235. The third bidirectional link 235 may be associated with a frequency F2 in a licensed radio frequency spectrum band. The second bidirectional link 230 may provide an offload of downlink and uplink capacity to the first base station 205. Like the supplemental downlink described above, this situation may occur with any service provider (e.g., MNO) that utilizes a frequency spectrum licensed radio station and needs to alleviate some of the traffic and/or signaling congestion.

[0097] In another example of a carrier aggregation mode in wireless communication system 200, the first base station 205 may transmit OFDMA waveforms to the third UE 217 using a fourth bidirectional link 240 and may receive OFDMA waveforms. , SC-FDMA waveforms, and/or resource block interleaved waveforms from the third UE 217 using the fourth bidirectional link 240. The fourth bidirectional link 240 may be associated with a frequency F3 in the frequency spectrum band unlicensed radio. The first base station 205 may also transmit OFDMA waveforms to the third UE 217 using a fifth bidirectional link 245 and may receive SC-FDMA waveforms from the third UE 217 using a fifth bidirectional link 245. The fifth bidirectional link 245 may be associated with frequency F2 in the licensed radio frequency spectrum band. The fourth bidirectional link 240 may provide an offload of downlink and uplink capacity to the first base station 205. This example and those provided above are presented for illustration purposes and there may be other similar modes of operation or development situations that combine LTE /LTE-A in a licensed radio frequency spectrum band and utilize an unlicensed radio frequency spectrum band for capacity offloading.

[0098] As described above, one type of service provider that can benefit from the capacity offload offered by utilizing LTE/LTE-A in an unlicensed radio frequency spectrum band is a traditional MNO with access rights to a licensed LTE/LTE-A radio frequency spectrum band. For these service providers, an operational example may include a bootstrapped mode (e.g., supplemental downlink, bearer aggregation) that utilizes an LTE/LTE-A Primary Component Carrier (PCC) in the licensed radio frequency spectrum band and at least one secondary component carrier (SCC) in the unlicensed radio frequency spectrum band.

[0099] In bearer aggregation mode, data and control may, for example, be communicated in the licensed radio frequency spectrum band (e.g., via first bidirectional link 225, third bidirectional link 235, and fifth bidirectional link 245). while data may, for example, be communicated in the unlicensed radio frequency spectrum band (e.g., via second bidirectional link 230 and fourth bidirectional link 240). The carrier aggregation mechanisms supported when utilizing an unlicensed radio frequency spectrum band may be under a hybrid time-division duplexing and frequency-division duplexing (FDD-TDD) carrier aggregation or a hybrid aggregation of TDD-TDD carrier with different symmetry across the component carriers.

[0100] In an example of an independent mode in wireless communication system 200, the second base station 206 may transmit OFDMA waveforms to the fourth UE 218 using a bidirectional link 250 and may receive OFDMA waveforms, waveforms SC-FDMA and/or FDMA waveforms interleaved with resource block from the fourth UE 218 using bidirectional link 250. Bidirectional link 250 may be associated with frequency F3 in the unlicensed radio frequency spectrum band. Standalone mode can be used in non-traditional wireless access situations, such as access within stadiums (e.g., unicast, multicast). An example of a type of service provider for this mode of operation might be a stadium owner, cable company, event host, hotel, business, or large corporation that does not have access to a licensed radio frequency spectrum band.

[0101] In some examples, a transmitting apparatus such as one of the base stations 105, 205 and/or 206 described with reference to Figure 1 and/or 2, and/or the UEs 115, 215, 216, 217 and/or 218 described with reference to Figure 1 and/or 2, may use an opening slot to gain access to a channel of an unlicensed radio frequency spectrum band (e.g., to a physical channel of the radio frequency spectrum band unlicensed). The opening interval may define the application of a contention-based protocol, such as a listen-before-talk (LBT) protocol based on the LBT protocol specified in the European Telecommunications Standards Institute (ETSI) (EN 301 893). When using an opening interval that defines the application of an LBT protocol, the opening interval may indicate when a transmitting apparatus needs to perform a containment procedure, such as a channel free evaluation (CCA) procedure. The result of the CCA procedure may indicate to the transmitting device whether a channel from an unlicensed radio frequency spectrum band is available or in use for the opening range (also referred to as an LBT radio frame or a CCA frame). When a CCA procedure indicates that the channel is available (e.g., "cleared" for use) for a corresponding LBT radio frame, the transmitting apparatus may reserve and/or use the radio frequency spectrum band channel in the licensee during part or all of the LBT radio frame. When the CCA procedure indicates that the channel is not available (for example, that the channel is in use or reserved by another device), the transmitting device may be prevented from using the channel during the LBT radio frame.

[0102] In some examples, it may be useful for a transmitting apparatus to generate an aperture interval for an unlicensed radio frequency spectrum band periodically and synchronize at least one boundary of the aperture interval with at least one boundary of a periodic interval. . For example, it may be useful to generate a periodic opening interval for a cellular downlink in a shared radio frequency spectrum band, and synchronize at least one edge of the periodic opening interval with at least one edge of a periodic interval (e.g. example, a periodic LTE/LTE-A radio slot) associated with the cellular downlink.

[0103] Figure 3 illustrates an example 300 of a wireless communication 310 over an unlicensed radio frequency spectrum band, in accordance with various aspects of the present description. An LBT radio frame 315, which may correspond to an aperture interval, may have a duration of ten milliseconds and include a number of downlink subframes 320, a number of uplink subframes 325, and two types of special subframes (e.g., an S 330 subframe and an S' 335 subframe). Subframe S 330 may provide a transition between downlink subframes 320 and uplink subframes 325, while subframe S' 335 may provide a transition between uplink subframes 325 and downlink subframes 320. During subframe S 330, a procedure Uplink CCA (UCCA) 340 may be performed by one or more UEs, such as one or more of the UEs 115, 215, 216, 217 and/or 218 described above with reference to Figure 1 and/or 2, to reserve, for a period of time, the channel over which wireless communication 310 occurs. Following a successful UCCA procedure 340 by a UE, the UE may transmit channel utilization signaling signal (CUBS) 345 to provide an indication to other UEs and/or appliances (e.g., base stations, Wi-Fi access points). -Fi, etc.) that the UE has reserved the channel. In some examples, a CUBS 345 may be transmitted using a plurality of interleaved resource blocks, as described in greater detail with reference to FIG. 6. Transmission of a CUBS 345 in this manner may allow CUBS 345 to occupy at least a percentage determined from the available frequency bandwidth in the unlicensed radio frequency spectrum band and satisfy one or more regulatory requirements (e.g., a requirement that CUBS 345 occupy at least 80% of the available frequency bandwidth). CUBS 345 may, in some examples, take a form similar to that of an LTE/LTE-A cell specific reference signal (CRS) and/or channel state information reference signal (CSI-RS). When the UCCA 340 procedure fails, CUBS 345 is not transmitted.

[0104] Subframe S 330 may include 14 OFDM symbols, numbered 0 to 13 in Figure 3. A first portion of subframe S 330, symbols 0 to 3, in this example, may be used as a downlink pilot time partition ( DwPTS) 350, and a second part of subframe S 330 may be used as a protection period (GP) 355. A third part of subframe S 330 may be used for a UCCA procedure 340. In example 300, subframe S 330 includes seven UCCA partitions, included in symbols t through 12. The use of UCCA partitions by different UEs can be coordinated to provide more efficient system operation. In some examples, in order to determine which of the seven possible UCCA partitions to use to perform a UCCA procedure 340, a UE may evaluate a mapping function of the form: FU (Groupld,t) e{1, 2, 3,4, ,5 6, 7} where GroupID where is a "development group ID" assigned to the UE, and t is the LBT radio frame number corresponding to a frame for which a UCCA procedure 340 is performed.

[0105] The mapping function for a UCCA procedure 340 can be constructed based on different criteria depending on whether the mapping function will have an orthogonalization or non-orthogonalization property. In examples with orthogonal LBT access, the mapping function can have an orthogonalization property according to: FD/U(X, t) Φ FD/u(y,t) GroupID x, y e {1, 2, 3, 4 , 5, 6, 7} for all time t, whenever x Φ y represent different group ids. In this case, base stations and/or UEs with different group ids may perform CCA procedures (e.g., UCCA 340 procedures) during non-overlapping CCA partitions. In the absence of interference, the UE with the group id that maps to a previous CCA partition can secure the channel for a period of time. According to various developments, the mapping function is fair, in the sense that across different time indices t, the mapping {FD/U(x,t),t=,1, 2, 3,...} varies so that different group ids have an equal chance of mapping to a previous CCA partition (and thus guaranteeing the channel in the absence of other interference) over a suitably long time interval.

[0106] All base stations and UEs developed by the same network operator/service provider can be assigned the same group id, so as not to exclude each other in the competition process. This allows full frequency reuse between base stations and UEs of the same deployment, resulting in improved system throughput. Base stations and/or UEs of different deployments can be assigned different group IDs, so that with orthogonal CCA partition mapping, channel access is mutually exclusive.

[0107] In examples with non-orthogonal or overlapping CCA partition access, the mapping function may allow more than seven group ids. In some situations, for example, it may be useful to support more than seven development group ids, in which case it is not possible to maintain the orthogonality property of the CCA partition mapping functions. In such cases, it may be desirable to reduce the collision frequency between any two group ids. In some examples, non-orthogonal CCA partition mapping sequences can also be used to provide fair channel access between developments without fair coordination of LBT opportunities. An example of a non-orthogonal CCA partition mapping sequence is given by FD/U(x,t) = R1,7(x,t) GroupIDx = e {1, 2,...,216} where R1,7 (x,t) is an independently chosen pseudorandom number generator between 1 and 7 for GroupIDx. In this case, there may be potential collisions between base stations and/or UEs of different GroupIDs in the same LBT t radio frame.

[0108] In this way, CCA partitions can be selected according to the noted mapping functions and used for a UCCA procedure 340.

[0109] In figure 3, the duration of each UCCA 340 procedure is fixed. However, in some examples, the duration of a UCCA procedure may vary.

[0110] Figure 4a illustrates an example 400 of a UCCA procedure 415 performed by a UE competing for access to an unlicensed radio frequency spectrum band, in accordance with various aspects of the present description. The UCCA 415 procedure may have a fixed duration and may be performed in a similar manner to the UCCA 340 procedure described with reference to Figure 3. In some examples, the UCCA 415 procedure may be performed in accordance with an LBT frame-based equipment protocol. (LBT-FBE) (e.g. the LBT-FBE protocol described by EN 301 893). Following the UCCA 415 procedure, a CUBS 420 can be transmitted, followed by an uplink transmission. By way of example, the uplink transmission may have an intended duration 405 of three subframes and an actual duration 410 of three subframes. In some examples, the uplink transmission may include a transmission of an uplink control channel, such as physical uplink control channel (PUCCH) and/or enhanced or evolved PUCCH (ePUCCH).

[0111] Figure 4B illustrates an example 450 of an extended CCA (ECCA) procedure 430 performed by a UE competing for access to an unlicensed radio frequency spectrum band, in accordance with various aspects of the present description. The ECCA 430 procedure may have a variable duration and be performed as an alternative to the UCCA 340 and/or 415 procedure described with reference to Figure 3 and/or 4. In some examples, the ECCA 430 procedure may be performed in accordance with a protocol of LBT load-based equipment (LBT-LBE) (e.g. the LBT-LBE protocol described by EN 301 893). The ECCA 430 procedure may provide a greater probability of winning the competition for access to the unlicensed radio frequency spectrum band, but at the potential cost of shorter uplink transmission. Following the ECCA 430 procedure, a CUBS 435 can be transmitted, followed by an uplink transmission. By way of example, the uplink transmission may have an intended duration 405 of three subframes and an actual duration 425 of two subframes. In some examples, the uplink transmission may include a transmission of an uplink control channel, such as PUCCH and/or ePUCCH.

[0112] Figure 5 illustrates an example 500 of resource allocations for CCA-Exempt Transmissions (CETs) of synchronized operators in an unlicensed radio frequency spectrum band, in accordance with various aspects of the present description. A CET can be done without having to perform a CCA (for example, a DCCA or an uplink CCA (UCCA)) to first gain access to the unlicensed radio frequency spectrum band. Instead, an operator may not need to perform a CCA for the purposes of transmitting a CET.

[0113] As illustrated, a resource allocation 505 to CETs may be made, for example, once every eighty milliseconds (80 ms) or once every CET period, where the CET period may have a configurable periodicity. Each of the operators (e.g., different PLMNs) in the unlicensed radio frequency spectrum band may receive a separate subframe (illustrated) or subframes (not illustrated) for transmitting CETs. By way of example, Figure 5 illustrates adjacent CET subframes for seven different operators (e.g. operators PLMN1, PLMN2,...,PLMN7). Such a CET transmission framework may be applicable to a downlink and/or uplink between a base station and a UE. In some examples, a CET may be used by a wireless device (e.g., a UE) to transmit uplink control information.

[0114] Figure 6 illustrates a diagram 600 of a component carrier (CC) bandwidth (BW) in an unlicensed radio frequency spectrum band, in accordance with various aspects of the present description. In some examples, the BW CC may be divided into a plurality of interleavings 605, 610 and/or 615 of resource blocks 620, 625 and/or 630. Each of the interleavings 605, 610 and/or 615 may include a plurality of non-contiguous simultaneous resource blocks, which resource blocks may be spaced in frequency according to a uniform spreading pattern or a non-uniform spreading pattern. By way of example, Figure 6 illustrates a plurality of interleavings (e.g., ten interleavings), with each interleaving having resource blocks (e.g., ten resource blocks) spaced in frequency according to a uniform spreading pattern. In some examples, each of the interlaces 605, 610 and/or 615 may comprise a greater portion of the BW CC.

[0115] In some examples, each of the plurality of wireless devices (e.g., one or more wireless devices) may utilize each of the interleavings 605, 610 and/or 615 of the resource blocks to transmit a control control channel. uplink (e.g., an enhanced or evolved PUCCH (ePUCCH)) across the unlicensed radio frequency spectrum band. Each of the uplink control channels may include, for example, hybrid automatic repeat request (HARQ) acknowledgment information (e.g., HARQ acknowledgments (ACKs) and/or negative acknowledgments (NAKs)) for a downlink transmission received from a base station on a wireless device over the unlicensed radio frequency spectrum band and/or channel state information (CSI) for the unlicensed radio frequency spectrum band . In some examples, the uplink control channel may be transmitted using a single-carrier frequency division multiple access (SC-FDMA) format. In some examples, the wireless devices may be examples of UEs 115, 215, 216, 217 and/or 218 described with reference to Figure 1 and/or 2.

[0116] Each of the various uplink control channels transmitted using the component carrier bandwidth illustrated in Figure 6 can utilize the resource in several discrete dimensions. The way in which resources are allocated and/or selected for use by the number of uplink control channels can determine a wireless device's wireless device capacity and component carrier bandwidth payload capacity.

[0117] Figure 7 illustrates a diagram 700 of a resource block 705 having a PUCCH format from a group consisting of format 1, format 1a, format 1b, in accordance with various aspects of the present description. In some examples, resource block 705 may be an example of one or more of the resource blocks described with reference to Figure 6 (e.g., one or more of resource blocks 620, 625 and/or 630).

[0118] By way of example, resource block 705 may include a plurality of resource elements (including, for example, resource element 710 and/or 715) extending in the dimensions of time and/or frequency. In some examples, resource block 705 may include resource elements spanning 14 OFDM symbols (numbered 0 to 13), two partitions 720 and 725, a subframe 730, and 12 frequency subcarriers spanning a bandwidth (BW). In some examples, the duration of subframe 730 may be one millisecond.

[0119] In accordance with LTE/LTE-A standards, a resource block 705 having a PUCCH format from a group consisting of format 1, format 1a and format 1b may include multiplexed information in the ZC sequences. Such resource block 705 may also include three reference symbols (e.g., three demodulation reference signals (DM-RS), including DM-RS resource elements) and four quadrature phase shift keying data symbols ( QPSK) (including data resource elements) per partition 720 and 725. The three reference symbols per partition provide time domain spreading (three Discrete Fourier Transform (DFT) sequences of length three) and frequency domain spreading (12 cyclical changes). The four QPSK data symbols per partition also provide time domain spreading (four Hadamard sequences) and frequency domain spreading (12 cyclic shifts). The maximum number of wireless devices that can utilize resource block 705 is the minimum of {3x12, 4x12} or 36 wireless devices. In some examples, the wireless devices may be UEs such as UEs 115, 215, 216, 217 and/or 218 described with reference to Figure 1 and/or 2. The maximum payload size that can be allocated to each device without wire in one millisecond (e.g., one subframe), when the maximum number of wireless devices are using resource block 705, is two bits.

[0120] Figure 8 illustrates a diagram 800 of a resource block 805 having a PUCCH format from a group consisting of format 2, format 2a, format 2b and format 3, in accordance with various aspects of the present description. In some examples, resource block 805 may be an example of one or more of the resource blocks described with reference to Figure 6 (e.g., one or more of resource blocks 620, 625 and/or 630).

[0121] By way of example, resource block 805 may include a plurality of resource elements (including, for example, resource element 810 and/or 815) extending in the dimensions of time and/or frequency. In some examples, resource block 805 may include resource elements spanning 14 OFDM symbols (numbered 0 to 13), two partitions 820 and 825, a subframe 830, and twelve frequency subcarriers spanning a bandwidth (BW). In some examples, the duration of subframe 830 may be one millisecond.

[0122] In accordance with LTE/LTE-A standards, a resource block 805 having a PUCCH format from a group consisting of format 2, format 2a and format 2b may include the information multiplexed into the ZC sequences. Such resource block 805 may also include two reference symbols (e.g., two DM-RS, including DM-RS resource elements) and five QPSK data symbols (including data resource elements) per partition 820 and 825. The two reference symbols per partition provide the time domain spread (two Hadamard sequences of length two) and frequency domain spread (12 cyclic shifts). The five QPSK data symbols per partition provide frequency domain spreading (12 cyclic shifts). When using format 2a and format 2b, the data symbols can be multiplexed into the two reference symbols. The maximum number of wireless devices that can use resource block 805 is the minimum of {2x12, 12} or 12 wireless devices. In some examples, the wireless devices may be UEs such as UEs 115, 215, 216, 217 and/or 218 described with reference to Figure 1 and/or 2. The maximum payload size that can be allocated to each wireless device in one millisecond (e.g., a subframe) when the maximum number of wireless devices using resource block 805 is 2 time partitions * 2 QPSK data symbols * 5 resource elements = 20 bits.

[0123] Also in accordance with LTE/LTE-A standards, a resource block 805 having a PUCCH 3 format may include information multiplexed into ZC sequences. Such resource block 805 may also include two reference symbols (e.g., two DM-RS) and twelve QPSK data symbols per partition 820 or 825. The two reference symbols per partition provide time domain spreading (two Hadamard sequences of length equal to two) and frequency domain spreading (12 cyclic shifts). The twelve QPSK data symbols per partition provide time domain spreading (5 sequences). The maximum number of wireless devices that can use resource block 805 is five. In some examples, the wireless devices may be UEs such as UEs 115, 215, 216, 217 and/or 218 described with reference to Figure 1 and/or 2. The maximum payload size that can be allocated to each device without wire is one millisecond (e.g., one subframe) when the maximum number of wireless devices using resource block 805 is 2 time partitions * 2 QPSK data symbols * 12 resource elements = 48 bits.

[0124] In some examples, an interleaving of resource blocks such as one of the interleavings 605, 610 or 615 of resource blocks described with reference to FIG. 6, and/or a plurality of resource block formats such as PUCCH formats described 7 and/or 8, may provide a plurality of discrete dimensions for the resources available for transmission of an uplink control channel (e.g., an ePUCCH) across an unlicensed radio frequency spectrum band. The discrete dimensions may include, for example, a plurality of resource block formats (e.g., PUCCH formats including format 1, format 1a, format 1b, format 2, format 2a, format 2b and/or format 3. The dimensions Discrete information may also include or may alternatively include an information block-to-resource mapping where, for example, different pieces of information (e.g., acknowledgment information and/or CSI) may be mapped to (and transmitted through) different blocks or subsets of resource blocks of an interleave and/or the same information may be mapped to (and transmitted through) each of the resource blocks of an interleave. Discrete dimensions may also or may alternatively include the use of information from code level acknowledgment, where bits of acknowledgment information indicate whether an individual code block or group of code blocks of a downlink transmission were received correctly and/or the use of acknowledgment information of transport block, where the acknowledgment information bits indicate whether an individual transport block or group of transport blocks of a downlink transmission was received correctly. The discrete dimensions may also or may alternatively include the generation of acknowledgment information for individual code blocks (or individual transport blocks) and/or the generation of acknowledgment information for code block groups (or groups of transport blocks) through hybrid automatic repeat request (HARQ) processes. In this way, a choice of three PUCCH formats (e.g., format 1a/1b, format 2, and format 3) defining a discrete first dimension, the use of information block-to-feature mapping, or repeated (redundant) mapping defining a second dimension discrete, the use of code block level or transport block level acknowledgment information defining a third discrete dimension, and the use of individual code block or transport block acknowledgment information or acknowledgment of group code block or transport block (through HARQ processes) defining a fourth discrete dimension can provide twenty-four alternatives for allocating resources for an uplink control channel transmitted across a frequency spectrum band unlicensed radio.

[0125] With reference to Figure 7, it was indicated that the maximum number of wireless devices that can utilize a resource block 705 having a PUCCH 1b format is 36 wireless devices. However, in the presence of delay spread across the frequency spectrum, the maximum number of wireless devices that can utilize the resource block to transmit an uplink control channel (for example, an ePUCCH) can be equal to 18. With reference 8, it was indicated that the maximum number of wireless devices that can use a resource block 805 having a PUCCH 2 format is twelve wireless devices. However, in the presence of delay spread in the frequency spectrum, the maximum number of wireless devices that can utilize resource block 805 to transmit an uplink control channel (e.g., an ePUCCH) can be equal to six. Thus, the orthogonal wireless device (user) resource block capacity is equal to 18 for a 705 resource block having a PUCCH 1b format, six for an 805 resource block having a PUCCH 2 format, and five for a resource block 805 having a PUCCH 3 format. Similarly, the capacity of the orthogonal wireless device (user) per interleaving (e.g., per ten resource blocks in the context of one of the interleavings 605, 610 or 615 described with reference to Figure 6) is equal to 18 for a 705 resource block having a PUCCH 1b format, six for an 805 resource block having a PUCCH 2 format, and five for an 805 resource block having a PUCCH 3 format.

[0126] Referring to Figure 7, the maximum payload capacity of a resource block having a PUCCH 1b format is 2 bits/wireless device * 36 wireless devices = 72 bits. However, in some examples, the payload capacity of a resource block 705 having a PUCCH 1b format, when a maximum number of wireless devices are utilizing the resource block to transmit an uplink control channel (e.g., an ePUCCH), can be 36 bits (e.g. 6 cyclic shifts and 3 time domain codes). Referring to Figure 8, the maximum payload capacity of a resource block having a PUCCH 2 format is 20 bits/wireless device * 12 wireless devices = 240 bits. However, in some examples, the payload capacity of a resource block 805 having a PUCCH 2 format when a maximum number of wireless devices are utilizing the resource block to transmit an uplink control channel (e.g., an ePUCCH), can be 60 bits (e.g. 6 cyclic shifts and a code rate of 0.5). Referring to Figure 8, the maximum payload capacity of a resource block having a PUCCH 3 format is 48 bits/wireless device * 5 wireless devices = 240 bits. However, in some examples, the payload capacity of a resource block 805 having a PUCCH 3 format when a maximum number of wireless devices are utilizing the resource block to transmit an uplink control channel (e.g., an ePUCCH) can be 120 bits (for example, a code rate of 0.5). Thus, the payload capacity per resource block (using all discrete dimensions) is equal to 36 bits for a 705 resource block having a PUCCH 1b format, 60 bits for an 805 resource block having a PUCCH 2 format, and 120 bits for a resource block 805 having a PUCCH 3 format. The payload capacity per interleaving (e.g., per ten resource blocks in the context of one of the interleavings 605, 610 or 615 described with reference to FIG. 6, and using all discrete dimensions), assuming information is repeated across all resource blocks of the interleave, is 36 bits for a 705 resource block having a PUCCH 1b format, 60 bits for an 805 resource block having a PUCCH format 2 and 120 bits for a resource block 805 having a PUCCH 3 format. The interleaving payload capacity (e.g., per ten resource blocks in the context of one of the interleavings 605, 610 or 615 described with reference to FIG. 6 and using all discrete dimensions), assuming that information is not repeated across all interleaving resource blocks (e.g., transmitted in one interleaving resource block), is 10 * 36 = 360 bits for a 705 resource block having a PUCCH 1b format, 10 * 60 = 600 bits for an 805 resource block having a PUCCH 2 format and 10 * 120 = 1200 bits for an 805 resource block having a PUCCH 3 format.

[0127] In a first example of allocating and/or selecting resources for use in transmitting an uplink control channel (e.g., an ePUCCH) across an unlicensed radio frequency spectrum band, PUCCH 1b format may be allocated and/or selected in a first dimension, the mapping from block of information to individual resource can be allocated and/or selected in a second dimension, the use of transport block level acknowledgment information can be allocated and /or selected in a third dimension, and the use of individual transport block acknowledgment information through the HARQ processes may be allocated and/or selected in a fourth dimension. Assuming that a wireless device (e.g., a UE such as one of the UEs 115, 215, 216, 217 and/or 218 described with reference to Figure 1 and/or 2) receives an interleaving of ten resource blocks, interleaving and resource blocks which are configured as described, for example, with reference to Figures 6 and 7, the resource allocation and/or resource selection example described in that paragraph may allow eighteen wireless devices to share resources within an interleaving, with each user using one ZC resource per resource block. The resource allocation and/or selection example described in this paragraph may also allow each of the eighteen wireless devices to transmit twenty bits of information. Alternatively, and by way of example, if the number of wireless devices sharing the interleaving is reduced to seventeen, each of the sixteen wireless devices can utilize one ZC resource per resource block and transmit twenty bits of information, and a wireless device wire can utilize two ZC resources per resource block and transmit forty bits of information.

[0128] In a second example of allocating and/or selecting resources for use in transmitting an uplink control channel (e.g., an ePUCCH) across an unlicensed radio frequency spectrum band, PUCCH format 2 may be allocated and/or selected in a first dimension, the mapping from block of information to individual resource can be allocated and/or selected in a second dimension, the use of transport block level acknowledgment information can be allocated and /or selected in a third dimension, and the use of individual transport block acknowledgment information through the HARQ processes may be allocated and/or selected in a fourth dimension. Assuming that a wireless device (e.g., a UE such as one of the UEs 115, 215, 216, 217 and/or 218 described with reference to Figure 1 and/or 2) receives an interleaving of ten resource blocks, interleaving and resource blocks which are configured as described, for example, with reference to Figures 6 and 8, the example of resource location and/or selection described in that paragraph may allow six wireless devices to share resources within a intertwining. The resource allocation and/or selection example described in this paragraph may also allow each of the six wireless devices to share resources within an interlock. The resource allocation and/or selection example described in this paragraph may also allow each of the six wireless devices to transmit 100 bits of information. Alternatively, and by way of example, if the number of wireless devices sharing the interleave is reduced to five, each of the four wireless devices can transmit 100 bits of information and one wireless device can transmit 200 bits of information.

[0129] In a third example of allocating and/or selecting resources for use in transmitting an uplink control channel (e.g., an ePUCCH) across an unlicensed radio frequency spectrum band, the PUCCH format 2 can be allocated and/or selected in a first dimension, the mapping from information block to individual resource can be allocated and/or selected in a second dimension, the use of transport block level acknowledgment information can be allocated and/or selected in a third dimension, and the use of individual transport block acknowledgment information through the HARQ processes may be allocated and/or selected in a fourth dimension. The acknowledgment information in this third example may include acknowledgment bits in which a joint encoding is performed, where, in some examples, the joint encoding may be a joint convoluted encoding. Assuming that a wireless device (e.g., a UE such as one of the UEs 115, 215, 216, 217 and/or 218 described with reference to Figure 1 and/or 2) receives an interleaving of ten resource blocks, which interleaving and resource blocks are configured as described, for example, with reference to Figures 6 and 8, the example resource allocation and/or selection described in that paragraph may allow six wireless devices to share resources within an interleaving. . The resource allocation and/or selection example described in this paragraph may also allow each of the six wireless devices to transmit 100 bits of information, or 50 bits of acknowledgment on which a joint encoding is performed.

[0130] In a fourth example of allocating and/or selecting resources for use in transmitting an uplink control channel (e.g., an ePUCCH) across an unlicensed radio frequency spectrum band, PUCCH format 3 may be allocated and/or selected in a first dimension, the mapping from block of information to individual resource can be allocated and/or selected in a second dimension, the use of transport block level acknowledgment information can be allocated and /or selected in a third dimension, and the use of individual transport block acknowledgment information through HARQ processes may be allocated and/or selected in a fourth dimension. Assuming that a wireless device (e.g., a UE such as one of the UEs 115, 215, 216, 217 and/or 218 described with reference to Figure 1 and/or 2) receives an interleaving of ten resource blocks, interleaving and resource blocks which are configured as described, for example, with reference to Figures 6 and 8, the resource allocation and/or selection example described in that paragraph may allow five wireless devices to share resources within an interleaving , with each user using one code division multiplexed (CDM) resource per resource block. The resource allocation and/or selection example described in this paragraph may also allow each of the five wireless devices to transmit 240 bits of information. Alternatively, and by way of example, if the number of wireless devices sharing the interleaving is reduced to four, each of the three wireless devices can utilize one CDM resource per resource block and transmit 240 bits of information, and a device without wire can utilize two CDM resources per resource block and transmit 480 bits of information.

[0131] In a fifth example of allocating and/or selecting resources for use in transmitting an uplink control channel (e.g., an ePUCCH) across an unlicensed radio frequency spectrum band, the PUCCH format 2 can be allocated and/or selected in a first dimension, the mapping from block of information to individual resource can be allocated and/or selected in a second dimension, the use of a code block level acknowledgment information can be allocated and/or selected in a third dimension, and the use of individual code block acknowledgment information through HARQ processes may be allocated and/or selected in a fourth dimension. Assuming that a wireless device (e.g., a UE such as one of the UEs 115, 215, 216, 217, and/or 218 described with reference to Figure 1 and/or 2) receives an interleaving of ten resource blocks , interleaving and resource blocks which are configured as described, for example, with reference to Figures 6 and 8, the example of resource allocation and/or selection described in that paragraph may allow six wireless devices to share resources within a intertwining. The resource allocation and/or selection example described in this paragraph may also allow each of the six wireless devices to transmit 100 bits of information. For a 20 Megahertz (MHz) component carrier in the unlicensed radio frequency spectrum band with four spatial layers, the maximum number of code blocks for which acknowledgment information may be transmitted may be less to or equal to fifty. Additionally, code block-level HARQ can be employed.

[0132] In a sixth example of allocating and/or selecting resources for use in transmitting an uplink control channel (e.g., an ePUCCH) across an unlicensed radio frequency spectrum band, PUCCH format 3 may be allocated and/or selected in a first dimension, the mapping from block of information to individual resource can be allocated and/or selected in a second dimension, the use of code block level acknowledgment information can be allocated and /or selected in a third dimension, and the use of individual code block acknowledgment information through HARQ processes may be allocated and/or selected in a fourth dimension.

The resource allocation and/or selection example described in this paragraph may also allow each of the five wireless devices to transmit 240 bits of information. For a 20 Megahertz (MHz) component carrier in the unlicensed radio frequency spectrum band with four spatial layers, the maximum number of code blocks for which acknowledgment information may be transmitted may be less than or equal to fifty. Additionally, code block level HARQ can be employed.

Alternatively, the functions may be performed by one or more other processing units (or cores) on one or more integrated circuits. In other examples, other types of integrated circuits may be used (e.g., Structured/Platform ASICs, Field Programmable Gate Assemblies (FPGAs), and other semi-custom ICs) that may be programmed in any manner known in the art.

A CDMA system may implement a radio technology such as CDMA2000, Universal Terrestrial Radio Access (UTRA), etc. CDMA2000 covers IS-2000, IS-95 and IS-856 standards. IS-2000 Version 0 and A is commonly referred to as CDMA2000 1X, 1X, etc. IS-856 (TIA-856) is commonly referred to as CDMA2000 1xEV-DO), High Rate Packet Data (HRPD), etc. UTRA includes Broadband CDMA (WCDMA) and other variations of CDMA. A TDMA system can implement a radio technology such as Global System for Mobile Communications (GSM). An OFDMA system can implement radio technology such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA), IEEE 802.11 (WiFi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM™, etc. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and LTE-Advanced (LTE-A) are new versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A and GSM are described in documents from an organization called the "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization called the "3rd Generation Partnership Project 2" (3GPP2). The techniques described here can be used for radio systems and technologies mentioned above in addition to other radio systems and technologies, including cellular communications (e.g., LTE) over unlicensed and/or shared bandwidth. The above description, however, describes an LTE/LTE-A system for example purposes, and the LTE terminology is used in much of the above description, although the techniques are applicable beyond LTE/LTE-A applications.

[0317] The detailed description presented above with respect to the attached drawings describes examples and does not represent all examples that can be implemented or that are within the scope of the claims. The terms "example" and "illustrative" when used in this description mean "serving as an example, case or illustration" and not "preferred" or "advantageous over other examples." The detailed description includes specific details for the purpose of providing an understanding of the techniques described. These techniques, however, can be practiced without these specific details. In some cases, well-known structures and apparatus are illustrated in block diagram form to avoid obscuring the concepts of the examples described.

[0318] Information and signals can be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols and chips that may be referred to throughout the above description may be represented by voltages, currents, electromagnetic waves, magnetic particles or fields, optical particles or fields or any combination of the same.

A general-purpose processor may be a microprocessor, but in the alternative, the processor may be any conventional processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices, for example, a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other similar configuration.

[0320] The functions described here can be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions may be stored in or transmitted as one or more instructions or code on a non-transitory computer-readable medium. Other examples and implementations are within the scope and spirit of the attached description and claims. For example, due to the nature of software, the functions described above may be implemented using software executed by a processor, hardware, firmware, wiring, or combinations thereof. Accessories implementing functions may also be physically located in various positions, including distributed so that parts of the functions are implemented in different physical locations. As used herein, including in the claims, the term "and/or" when used in a list of two or more items, means that any one of the items listed may be employed alone, or any combination of two or more of the items listed may be employee. For example, if a composition is described as containing components A, B and/or C, the composition may contain A only, B only, C only, A and B in combination, A and C in combination, B and C in combination, or A, B and C in combination. Furthermore, as used herein, including in the claims, "or" as used in a list of items (e.g., a list of items introduced by a phrase such as "at least one of" or "one or more of") indicates a separate list so that, for example, a list of "at least one of A, B, or C" means A or B or C or AB or AC or BC or ABC (that is, A and B and C).

[0321] Computer-readable medium includes both storage medium and communication medium including any medium that facilitates the transfer of a computer program from one place to another. A storage medium can be any available medium that can be accessed by a general purpose or special purpose computer. By way of example, and not limitation, the computer-readable medium may comprise RAM, ROM, EEPROM, flash memory, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other a medium that can be used to carry or store desired program code media in the form of instructions or data structures and that can be accessed by a general purpose or special purpose computer, or a general purpose or special purpose processor. Furthermore, any connection is properly called a computer-readable medium. For example, if the software is transmitted from a network site, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL or wireless technologies such as infrared, radio and microwave are included in the definition of medium. Floppy disk and disc, as used herein, include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk, and Blu-ray disc where floppy disks typically reproduce data magnetically, while discs reproduce data optically with lasers. The above combinations are also included in the scope of computer-readable medium.
