Description

PRIORITY CLAIM [0001] The present application claims priority over US patent application serial number 14 / 318,076, filed on June 27, 2014, which claims priority over US provisional patent application no. Serial No. 61 / 924,194, filed on January 6, 2014, each of which is incorporated in this document by reference in its entirety.

FIELD OF THE INVENTION [0002] The embodiments refer to wireless communications. Some embodiments refer to the collection of geographic bin data on wireless networks. Some embodiments refer to Unit Test Minimization messages on a 3GPP network.

HISTORY [0003] A wireless network can be designed and implemented with the aim of supporting communication services between base stations and mobile devices during the most typical scenarios and use cases. These scenarios can be characterized by large variations in parameters that are significant for the network design, such as the load or the number of mobile devices that are expected to be active during

Petition 870160051065, of 9/13/2016, p. 9/188

2/41 different time periods. The initial design of the network can use statistical models of these parameters and this approach can provide a good starting point for the implementation of the network. However, the performance of an implemented network, even a well designed one, can be further optimized or improved based on current data collected in the field. As an example, the number of mobile devices operating in a specific geographic region at a given time of day or the typical signal strength received on these mobile devices may differ from what was initially predicted or modeled in the network design.

[0004] The collection of data of this nature can assist network designers or processes of self-organization or self-optimization that operate on the network. However, the amount of data collected for a typical geographic coverage region can be relatively large, particularly in occupied regions. The transmission of data via a backhaul from a base station to other components on the network for further processing may be impossible in these cases. In addition, a significant amount of data may not even be particularly useful and the transmission may cause congestion on the network or may hamper the processing of data that is useful.

Thus, there is a general need for systems and methods to collect, filter and send geographic bin data to other components for processing.

5/41 mobile device. The display screen can be an LCD screen including a touch screen.

[0014] FIG. 1 shows a portion of an end-to-end network architecture of an LTE network with various components of the network according to some embodiments. Network 100 comprises a radio access network (RAN) (eg, as shown, E-UTRAN or Evolved Universal Terrestrial Radio Access Network) 100 and nuclear network 120 (eg, presented as a core of evolved package (EPC)) coupled to each other through an S1 115 interface. For convenience and briefly, only a portion of the core network 120 is shown, as well as the RAN 100.

[0015] Core network 120 includes a mobility management entity (MME) 122, a service gateway (service GW) 124 and a packet data network port (PDN GW) 126. RAN 100 includes evolved B nodes (eNBs) 104 (which can be operated as base stations) to communicate with UE 102. eNBs 104 may include macro eNBs and reduced power (LP) eNBs.

[0016] The MME is similar, in function, to the control plan of Legacy Service GPRS Support Nodes (SGSN). MME manages aspects of access mobility such as selecting gateways and managing the crawl region list. Service GW 124 ends the interface in the direction of RAN 100 and serves data packets between RAN 100 and core network 120. In addition, it can be a local mobility anchor point for inter-eNB transmissions and

Petition 870160051065, of 9/13/2016, p. 13/188

6/41 can also provide an anchor for inter-3GPP mobility. Other responsibilities may include legal interception, loading and enforcement of some policies. Service GW 124 and MME 122 can be implemented on a physical node or on separate physical nodes. The GW PDN 126 terminates an SGi interface in the direction of the packet data network (PDN). The GW PDN 126 serves data packets between the EPC 120 and the external PDN and can be a key node for the execution of some policies and for loading data collection. It can also provide an anchorage point for mobility in non-LTE accesses. The external PDN can be any type of IP network, as well as an IP Multimedia Subsystem (IMS) domain. GW PDN 126 and service GW 124 can be implemented on a physical node or on separate physical nodes.

[0017] eNBs 104 (macro and micro) terminate the air interface protocol and can be the first point of contact for an UE 102. In some embodiments, an eNB 104 can fulfill several logical functions for RAN 100 including but not limited to RNC (radio network controller functionality) such as radio bearer management, management of dynamic uplink and downlink radio resources and scheduling of

packages in data and mobility management. In wake up with some forms in realization, the UEs 102 can to be configured for to communicate signals in Communication OFDM a an eNB 104 through a channel in

multiport communication according to a technique

Petition 870160051065, of 9/13/2016, p. 14/188

7/41 OFDMA communication. OFDM signals can comprise a plurality of orthogonal supports.

[0018] The S1 115 interface is the interface that separates RAN 100 and EPC 120. It is divided into two parts: S1-U, which supports data traffic between eNBs 104 and service GW 124, and, the S1-MME, which is a signaling interface between eNBs 104 and MME 122. The X2 interface is an interface between eNBs 104. The X2 interface comprises two parts, the X2-C and the X2-U. X2-C is the control plane interface between eNBs 104, while X2-U is the user plane interface between eNBs 104.

[0019] In cellular networks, LP cells are typically used to increase coverage for indoor regions that outside signals do not reach well or to add network capacity in regions where there is a very dense network usage, such as train stations. As used herein, the term low power eNB (LP) refers to any relatively low power eNB suitable for implementing a narrower cell (narrower than a macrocell) such as femtocell, picocell or a microcell. Femtocell eNBs are typically provided by a mobile network operator for their home or business customers. A femtocell is typically the size of a door

binding domestic or bottom and generally is connected to band line wide of user. An turn connected, the femtocell is connected to the mobile network of operator and providence extra coverage in a range in

Petition 870160051065, of 9/13/2016, p. 15/188

8/41 typically 30 meters to 50 meters in the case of domestic femtocells. Thus, an eNB LP can be a femtocell eNB as long as it is coupled via GW PDN 126. Similarly, a picocell is a wireless communication system typically covering a small region, such as building interiors (offices, shopping centers, train stations, etc.) or more recently aircraft interiors. An eNB picocell is usually connected via the X2 link to another eNB such as an eNB macro via its base station controller (BSC) functionality. Thus, eNB LP can be implemented with an eNB picocell as long as it is coupled to an eNB macro through an X2 interface. Picocell eNBs or other LP eNBs can incorporate some or all of the functionality of an eNB macro. In some cases, this can be referred to as an access point base station or a corporate femtocell.

[0020] In some embodiments, a downlink resource grid can be used for downlink transmissions from an eNB 104 to an UE 102. The grid can be a temperature-frequency grid, called the resource grid, which is the physical resource on the downlink in each slot. This representation of the time-frequency plan is a common practice for OFDM systems, which makes it intuitive for the allocation of radio resources. Each column and each row of the resource grid corresponds to an OFDM symbol and an OFDM subcarrier, respectively. The duration of the resource grid in the time domain corresponds to a

Petition 870160051065, of 9/13/2016, p. 16/188

9/41 slot in a radio structure. The smallest frequency-frequency unit in a resource grid is called a resource element. Each resource grid comprises a number of resource blocks, which describe the mapping of certain physical channels to resource elements. Each resource block comprises a set of resource elements and in the frequency domain it represents the smallest amount of resources that can currently be allocated. There are several different physical downlink channels that are transported using these resource blocks. Of particular relevance to this disclosure, two of these physical downlink channels are the physical downlink shared channel and the physical downlink control channel.

[0021] The physical downlink shared channel (PDSCH) carries user data and high layer signals to an UE 102 (FIG. 1). The physical downlink control channel (PDCCH) carries information relating to the transport format and resource allocations related to the PDSCH channel, among others. It also informs UE 102 regarding the transport format, resource allocation and H-ARQ information related to the uplink shared channel. Typically, downlink scheduling (assigning shared and control channel resource blocks to UEs 102 in a cell) is performed on eNB 104 based on the channel quality information returned from UEs 102 to eNB 104 and subsequently the relative information

Petition 870160051065, of 9/13/2016, p. 17/188

10/41 the downlink resource assignment is sent to a UE 102 on the control channel (PDCCH) used for (assigned to) the UE 102.

[0022] The PDCCH uses CCEs (control channel elements) to carry the control information. Before being mapped into resource elements, PDCCH complex value symbols are first organized into quadruples, which are subsequently exchanged using sub-block interleavers for rate matching. Each PDCCH is transmitted using one or more of these control channel elements (CCEs), where each CCE corresponds to nine sets of four physical resource elements known as resource element groups (REGs). Four QPSK symbols are mapped to each REG. The PDCCH can be transmitted using one or more CCEs, depending on the size of the DCI and the channel condition. There may be four or more different PDCCH formats defined in LTE with different numbers of CCEs (eg, aggregation level L = 1, 2, 4 or 8).

[0023] FIG. 2 shows a block diagram of an UE 200 according to some embodiments, while FIG. 3 shows a block diagram of an eNB 300 according to some embodiments. It should be noted that, in some embodiments, the eNB 300 can be a stationary non-mobile device. The UE 200 can be a UE 102 as shown in FIG. 1, while the eNB 300 can be an eNB 104 as shown in FIG. 1. UE 200 may include physical layer circuits 202 for transmitting and receiving

Petition 870160051065, of 9/13/2016, p. 18/188

11/41 signals to and from eNB 300, other eNBs, other UEs or other devices using one or more antennas 201, while eNB 300 may include physical layer circuits 302 to transmit and receive signals to and from UE 200, other eNBs, other UEs or other devices using one or more antennas 301. The UE 200 may further include media access control (MAC) layer circuits 204 to control access to the wireless medium, while the eNB 300 may further include medium access control layer (MAC) circuits 304 to control access to the wireless medium. The UE 200 may further include processing circuits 206 and memory 208 arranged to perform the operations described herein and the eNB 300 may further include processing circuits 306 and memory 308 arranged to perform the operations described herein.

[0024] Antennas 201, 301 may comprise one or more directional or omnidirectional antennas, including, for example, bipolar antennas, monopoly antennas, panel antennas, microwaveable antennas or other types of RF signal transmission.

realization of the type of frame scheme, antenna antennas suitable for the

In some forms of multiple input / multiple output (MIMO) communication, the 201, 301 antennas can be separated to take advantage of the spatial diversity and the resulting different channel characteristics.

[0025] Although the UE 200 and eNB 300, respectively, are illustrated as having several elements

Petition 870160051065, of 9/13/2016, p. 19/188

12/41 separate functional elements, one or more of the functional elements can be combined and can be implemented by combinations of software-configured elements, such as processing elements including digital signal processors (DSPs) and / or other hardware elements. For example, some elements may comprise one or more microprocessors, DSPs, programmable logic gate networks (FPGAs), application-specific integrated circuits (ASICs), radio frequency integrated circuits (RFICs) and combinations of various hardware and logic circuits to perform at least the functions described in this document. In some embodiments, the functional elements may refer to one or more processes operating on one or more processing elements.

[0026] The embodiments can be implemented in one or a combination of hardware, firmware and software. The embodiments can also be implemented as instructions stored on a computer-readable storage device, which can be read and executed by at least one processor to perform the operations described in this document. A computer-readable storage device can include any non-transitory mechanism for storing information in a machine-readable format (eg, a computer). For example, a computer-readable storage device may include read-only memory (ROM), random access memory (RAM),

Petition 870160051065, of 9/13/2016, p. 20/188

13/41 magnetic disk storage, optical storage media and other storage devices and media. Some embodiments can include one or more processors and can be configured with instructions stored on a computer-readable storage device.

[0027] According to some embodiments, eNB 104 can be configured to track geographic bin information for one or more UEs 102. eNB 104 can comprise hardware processing circuits for each of UEs 102, with based on a receipt of one or more packets from the UE 102, measure an arrival angle for the UE 102 and a propagation delay for the UE 102. The hardware processing circuits can be further configured to select, for each one of UEs 102, a geographical bin for UE 102 from a set of candidate geographical bins. In some embodiments, the selection may be based at least partially on the measurements of the angle of arrival and propagation delay. The hardware processing circuits can be further configured to send, for each of the candidate geographic bins, performance data to the candidate geographic bin to a Tracking Collection Entity (TCE) when a number of UEs 102 for which the bin candidate geographic is selected is not below the EU distribution threshold. These embodiments are described in more detail below.

[0028] According to FIG. 4, a 400 method for collecting and reporting geographic bin data is presented. IS

Petition 870160051065, of 9/13/2016, p. 21/188

14/41 it should be noted that embodiments of method 400 may include additional or even less operations or processes compared to what is illustrated in FIG. 4. Furthermore, embodiments of method 400 are not necessarily limited to the chronological order that is shown in FIG. 4. In describing method 400, reference can be made to FIGs. 1-3 and 5-7, although it is clear that method 400 can be practiced with any other suitable systems, interfaces and components. In addition, while method 400 and the other methods described in this document refer to UEs

102 operating in accordance with 3GPP standards and other standards, the embodiments of these methods are not limited to only those UEs 102 and can also be practiced on other mobile devices. In addition, method 400 and other methods described in this document can be practiced by wireless devices that are configured to operate on other suitable types of wireless communications systems, including systems that are configured to operate in accordance with various IEEE standards such as such as IEEE 802.11. [0029] In operation 405 of method 400, in an eNB 104, a geographic bin control message can be received from an MME, while in operation 410, a Control Test Minimization message

Unit (MDT) that includes an MDT activation parameter and a geographic bin information element (IE) can be received in eNB 104 from the MME. It is evident that the geographic bin control message and the geographic bin IE can be stand-alone messages or

Petition 870160051065, of 9/13/2016, p. 22/188

15/41 can be included as part of another control message or another message and, in some embodiments, the geographic bin control message

Geographic bin IE can even be the same entity.

In addition, the geographic bin control message or the geographic bin IE can be included as part of another control message designed or designed to support the collection and reporting of geographic bin data, but they can also be carried as part of existing and established control message. As an example, the geographic bin IE can be included as part of a

Unit Test Minimization (MDT), as known in the 3GPP technique and may or may not be related to the system's MDT functionality.

In these cases, the MDT message can carry or enter the geographic bin IE through the horse's door.

According to FIG. 5 an example of a geographic bin IE 500 is shown. It is evident that the geographic bin IE 500 or the geographic bin control message may include some or all of the parameters shown in FIG. 5 may include additional parameters not shown in FIG.

While some of the parameters in the

Geographic bin IE

500 may be related to the collection and reporting of geographic bin data, the geographic bin IE 500 may include other parameters or information 505, which may be related to other aspects of the system or eNBs

104 or 102 UEs that are configured to operate on the system.

Petition 870160051065, of 9/13/2016, p. 23/188

16/41 [0031] The geographic bin IE 500 can also include an arrival angle scale parameter 510, which can be called RangeForAoA or similar. The arrival angle scale parameter 510 can be used to configure a region of coverage of an eNB 104 in geographic bin, where each geographic bin is characterized by an angle of arrival of a wireless signal transmitted to eNB 104 from UE 102 located in the bin. The value of the arrival angle scale parameter 510 can be enumerated and can include, for example, an angle scale or an angle resolution to divide the coverage region into geographic bins or a number of angles at which the coverage region must be divided. The value of the arrival angle scale parameter 510 is not limited to these values, considering that any suitable parameter can be used that allows eNB 104 to divide the coverage region into geographic bins.

[0032] The geographic bin IE 500 can also include a propagation delay scale parameter 520, which can be called RangeForTadv or similar. The propagation delay scale parameter 520 can also be used to configure the region of coverage of eNB 104 in geographical bins, where each geographical bin is characterized by a propagation delay of a wireless signal transmitted to eNB 104 from UE 102 located in the bin. It is evident that, as known in the prior art, there is a relationship between propagation delay and distance. Therefore, a propagation delay associated with a geographical bin

Petition 870160051065, of 9/13/2016, p. 24/188

17/41 can also serve to characterize (exactly or approximately) the distance between the geographic bin and the eNB 104. It is also known in the art that, in some systems, measurements of propagation delay, whether unidirectional or bidirectional, can be collected on a base station or eNB 104 and communicated to the UE 102 in a control message or other message. Correspondingly, UE 102 can adjust or advance its transmission timing so that signals transmitted from UE 102 arrive at eNB 104 with the appearance of no propagation delay.

[0033] It is evident that the propagation delay scale parameter 520 can be used in conjunction with the arrival angle scale parameter 510 to divide the coverage region into two-dimensional geographic bins, as described above. In some embodiments, however, the propagation delay scale parameter 520 or the arrival angle scale parameter 510 can be used separately or in combination with other parameters to divide the coverage region into geographical bins. The value of the propagation delay scale parameter 520 can be enumerated and can include, for example, a propagation delay or a distance scale or a resolution to divide the coverage region into geographical bins. The value of the propagation delay scale parameter 520 is not limited to these values, considering that any suitable parameter that allows

Petition 870160051065, of 9/13/2016, p. 25/188

18/41 to eNB 104 divide the coverage region into geographic bins.

[0034] The geographic bin IE 500 can also include an average arrival angle window parameter 515, which can be called AoAGranularity or similar. In addition, the geographic bin IE 500 can also include an average propagation delay window parameter 525, which can be called

TadvGranularity or similar.

To allow a minimizing functionality for measurements made on geographic bins, measurements made on one or more adjacent geographic bins can be translated into averages in some way. For example, individual bin averages for each of the geographic bins can be formed by averaging the received signal strength indicators for the

UEs

102 located in the bin, as a first operation. A minimized moving average for each of the geographical bins can be performed by averaging the individual bin averages of the geographical bins and one or more adjacent geographical bins. As such, moving average data may be lighter than individual bin averages, particularly when some of the bins do not have sufficient sample sizes (such as

UEs 102 present in the bins) for measurements.

[0035] According to the moving average process described above, the average arrival angle window parameter 515 and the propagation delay window average parameter 525 can be used to specify or to determine the number of geographic bins adjacent to

Petition 870160051065, of 9/13/2016, p. 26/188

19/41

be used on average minimized or one size gives window in moving average . O parameter medium in window in angle in arrival 515 it's the parameter medium in window in delay in propagation 525 can be listed and can

include an angle scale, an angle resolution, a delay scale, a delay resolution, numbers that specify a window size in an angular or radial direction or any suitable quantity that allows the eNB 104 to perform the minimized moving averages of measurements .

[0036] The geographic bin IE 500 can also include a distribution calculation parameter of the UE 530, which can be called the UE distribution or similar. The UE 530 distribution calculation parameter can specify or direct the eNB 104 in order to measure or not perform calculations that are related to the UE distribution in the geographic bins. As an example, for each UE 102 operating in the coverage region, eNB 104 can assign UE 102 to a geographic bin and can also calculate the UE distributions that are related to each geographic bin. The UE distribution for a geographic bin can be a count of the number of

UEs 102 located in the bin.

Correspondingly, the UE 530 distribution calculation parameter can be Boolean, including values such as yes / no, similar and can refer to whether true / false or eNB 104 should or should not perform measurements or calculations of the UE distribution.

[0037] It is evident that the UE 102 can comprise one or more measurements of the received signal strength and / or the

Petition 870160051065, of 9/13/2016, p. 27/188

20/41 signal quality received at UE 102 based on a signal reception from eNB 104. In some embodiments, the received signal strength may be a received signal level (for example, in Watts), a received signal strength indicator (RSSI) or any suitable quantity that characterizes the received signal strength in the UE 102. In some embodiments, the quality of the received signal may be a signal-to-noise ratio (SNR), a carrier-to-interference ratio (C / I) or any suitable quantity that characterizes the signal quality received at UE 102. Correspondingly, measurement of received power or signal quality can be performed at any suitable location on UE 102. For example , the measurement can be performed at the front end of the UE 102 or it can be performed at the output of a demodulator at the UE 102. In addition, the received signal power or quality can be referred to in step terms or logarithmic (dB).

[0038] UE 102 can process or convert measurements into suitable indicators for communication to eNB 104. Indicators can include individual measurements, multiple measurements, average measurements or any suitable indicator of signal strength or quality received at UE 102. As for example, an average received signal strength indicator may be an average of the dB values of multiple individual measurements of received signal strength, such as RSSI. As such, packets sent from UE 102 to eNB 104 may include one or more indicators of

Petition 870160051065, of 9/13/2016, p. 28/188

21/41 received signal strength or received signal quality indicators. In addition, the use of thresholds, comparisons or averages of the received signal strength indicators or the received signal quality indicators described above can use these techniques and the thresholds and results can also be reported in similar units, such as staggered, logarithmic or dB.

[0039] The geographic bin IE 500 may also include a parameter for calculating the signal strength indicator bin 535, which can be called RSRP or similar. In addition, geographic bin IE 500 may further include a signal quality indicator bin calculation parameter 540, which may be referred to as RSRQ or the like. Both parameters can be Boolean, considering values such as yes / no, true / false or similar and can refer to whether or not eNB 104 should perform average calculations for the received signal strength indicator or the received signal quality indicator. of UEs 102 in each geographic bin.

[0040] The geographic bin IE 500 can also include a distribution threshold of UE 545, which can be called “Rep Trig UE Distribution or similar. The distribution threshold of UE 545 can specify a threshold in terms of the number of UEs 102, the percentage of UEs 102 or other suitable quantity. ENB 104 can use the UE 545 distribution threshold as part of a decision-making process to send or not report data to other components on the network (such as the

Petition 870160051065, of 9/13/2016, p. 29/188

22/41

TCE described above). As an example, when the number of UEs 102 determined to be operational in a specific geographic bin is less than the threshold specified by the UE 545 distribution threshold, that bin can be considered as sparsely populated. The data for that bin, such as the average received signal indicator or the UEs 102 quality indicator in that bin, can be considered irrelevant or useless. In these cases it can be determined that the data for that bin should not be sent or reported to the TCE or other network components.

[0041]

The geographic bin IE

500 can also include a signal strength indicator bin threshold 550, which can be referred to as “Rep

RSRP Trig or similar

The geographic bin IE

500 can also include a signal quality indicator bin threshold 555, which can be referred to as “Rep

RSRQ Trig or similar.

These two thresholds

550, 555 can be used in a similar or analogous way to the threshold of distribution of

UE 545. For a specific geographic bin, the power or signal quality indicators received from UEs 102 determined to be located in that bin can be translated into averages compared to the appropriate threshold 550 or 555. As an example, when the average of signal strength indicators received from UEs 102 in the bin is below the threshold

550, the data for that bin can be considered irrelevant or useless and therefore not be sent or reported to the TCE or other network components. Similar operations can be performed to

Petition 870160051065, of 9/13/2016, p. 30/188

23/41 the signal quality indicators received from the UEs

102 with the 555 threshold. It is clear that those regarding the relevance and usefulness of data for a specific geographic bin can be based on comparisons using any or all of the distribution thresholds of the

HUH

545, signal strength indicator bin threshold

550, signal quality indicator bin threshold

555 or other thresholds.

[0042]

The geographic bin IE 500 can also include a periodicity report parameter to be called PeriodicReporting or

560, which can similar. The periodicity report parameter 560 can inform or request that the UE 102 periodically report data to the TCE or other component on the network. The periodicity parameter 560 can also include a period of time that can define how often the data is reported, such as a second.

[0043] The geographic bin IE 500 can also include a zoom function container 565, which can be called ZoomFunction or similar. The zoom function container 565 can include information that informs eNB 104 to maximize or minimize geographic bins. Correspondingly, geographic bins can be reconfigured in response. As an example, reconfiguration can be performed according to the values currently in use for the arrival angle scale parameter 510 or the propagation delay scale parameter 520. A factor 2 minimization, for example, can be performed by dividing both the parameter

Petition 870160051065, of 9/13/2016, p. 31/188

24/41 arrival angle scale 510 as the propagation delay scale parameter 520 by two.

[0044]

The geographic bin IE 500 can also include a 570 detailed location reporting parameter, which can be called “Detailed Location

Information per

Geo Bin ”or similar.

The detailed location reporting parameter

570 can be boolean, considering values such as yes / no, true / false or similar and can refer if the eNB

104 should or should not include detailed location information, such as the coordinates of the Global

Browsing by

Satellite (GNSS), when sending or reporting data to the

TCE or other network component. As an example, for a specific geographic bin for which data is reported, the coordinates

GNSS determined to be the center of that bin can be included in the data.

As another example, the coordinates

GNSS of

UEs

102 determined to be located in that bin can be reported to the eNB

4 from each UE 102, such as in a control portion of a package. ENB 104 can average the coordinates

GNSS for UEs 102 in that bin and include that information as part of the data.

[0045]

Returning to method 400, in operation 415, a set of candidate geographical bins can be determined.

The determination can be based on the parameters described above received in the

Geographic bin IE

500, such as the arrival angle scale parameter 510 or the propagation delay scale parameter 520, but is not limited to these. Others

Petition 870160051065, of 9/13/2016, p. 32/188

25/41 parameters describing similar concepts can be communicated to eNB 104 in other messages or can be predefined or part of a standard. In either case, a non-limiting example for determining the set of candidate geographical bins is presented in FIG. 6 for an eNB 605, which may be the eNB 104 that supports UEs 102 operating in or located in coverage region 610. It should be noted that for purposes of illustration, the division of coverage region 610 into sectors is not shown, but it is well known in the art. In this example, several geographical bins 615-655 are shown, respectively with an angular coverage of approximately 30 degrees, which can be the value for the arrival angle scale parameter 510. The division of the coverage region 610 into 615-655 bins in the radial direction (on an axis approaching or moving away from the eNB 605) it is also carried out in such a way that the beginning and end of one of the 615-655 bins covers a certain distance in the radial direction. The distance, or a propagation delay difference that is related to this distance, can be the value for the propagation delay scale parameter 520. It is equally evident that although the example in FIG. 6 show what appears to be uniformly staggered geographic bins 615-655, the division of coverage region 610 is not limited to this division and non-uniform scales can be used. As an example, bins 625, 640, 655 located furthest from eNB 605 in FIG. 6 are larger than bins 615, 630, 645 located closer to eNB 605,

Petition 870160051065, of 9/13/2016, p. 33/188

26/41 an inherent result of geometry. A non-uniform scaling approach may use a lower value for angular coverage in regions further from eNB 605.

[0046] In operation 420 of method 400, eNB 104 can receive one or more packets from each of the UEs 102 in the system and based on the reception an arrival angle for the UE 102 and a

delay in spread to the UE 102 in the operation 425 . O angle in current arrival or determined can to be one angle in that signals tr allowed to from the HUH 102 arrive to eNB 104 and, for therefore, can indicate or

be related to an angle at which the UE 102 is physically located in relation to the eNB 104 or a suitable reference point. The determination of the arrival angle can be carried out using any suitable technique known in the prior art such as beam formation or other directional antenna techniques. The propagation delay can be determined using any suitable technique known in the prior art that is related to reception, including the correlation of a known sequence included in the packets to determine the delay as a difference between the sequence arrival time and a time of reference. As described above, the propagation delays associated with the transmission of signals between the UE 102 and the eNB 104 or the measurements or estimates of these delays, may indicate or may be related to a distance between the UE 102 and the eNB 104. As such , the arrival angle and propagation delay determined

Petition 870160051065, of 9/13/2016, p. 34/188

27/41 or estimated can be used to estimate a location of UE 102 in relation to eNB 104 and can be used to determine a geographic bin for UE 102. The angle of arrival and propagation delay and the location of UEs 102 can also be determined using location services such as GPS or GNSS.

[0047] In operation 430 of method 400, a geographical bin of the set of candidate geographical bins can be determined for each EU 102. The determination can be based on any or all of the arrival angle, propagation delay or others parameters or measurements. As an example, eNB 104 can determine, for each of the candidate sets of geographic bins, an angle associated with a bin center and an expected propagation delay based on the distance between the bin center and eNB 104. This information can be compared to the determined arrival angle and propagation delay of a specific UE 102 to determine a geographical bin for the UE 102. That is, the UE 102 can be assigned to that bin or can be considered to be located in that bin.

[0048] In operation 435 of method 400, for each candidate geographic bin, an average of bin of the signal quality indicators received for UEs 102 for which the candidate geographic bin is selected can be determined. The average bin can be an average value or a weighted average value. In operation 440, a minimized average of the bin averages for each candidate geographic bin can be determined. According to the example

Petition 870160051065, of 9/13/2016, p. 35/188

28/41 in FIG. 6, a minimized average for geographic bin 635 can be an average of the bin averages of geographic bin 635 and any or all adjacent bins 615-655 shown or other bins not shown. As an example, the bin averages for the nine geographic bins 615-655 can be translated into averages to produce the minimized average for bin 635. As another example, the minimized average can be performed only in the radial direction so that the minimized average for bin 635 is the average of bin averages for bins 630, 635 and 640. As another example, the minimized average can be performed only in the angular direction so that the minimized average for bin 635 is the average of the bin averages for bins 620, 635 and 650. The number of adjacent bins based on which the minimized average is to be performed can be specified, as noted above, by parameters such as the average arrival angle window parameter 515 , the propagation delay window average parameter 525 or other similar or predefined parameters.

In addition, while operations 435 and

440 are related to the quality of service indicators

102, signal received from the UEs may be performed similar operations related to other quantities in relation to the UEs 102, such as the signal strength indicators received from those UEs 102.

[0049] In operation 445 for any or all of the candidate geographic bins, geographic bin performance data can be sent to the TCE. In operation 450, the sending of geographic bin performance data

Petition 870160051065, of 9/13/2016, p. 36/188

29/41 can be restricted to any or all candidate geographic bins. As such, for a bin to which shipping is restricted, performance data from geographic bin to bin may be sent at a reduced frequency or may not be sent. As noted above, the decision to send or not geographic bin performance data to a specific candidate geographic bin can be based on comparisons of determined bin statistics with any or all of the EU 545 distribution thresholds, the signal strength indicator bin threshold 550, signal quality indicator bin threshold 555 or other thresholds. As an example, when the number of UEs 102 determined to be located in the bin is below the distribution threshold of UE 545, the sending of

performance in bin geographic to TCE can to be restricted or no accomplished. As a other example, when the average in bin or an average minimized From indicators in pot frequency of received signal or From indicators in signal quality received from these UEs 102 is lower at l imitate suitable 550 or 555 sending of the data in bin geographic to TCE can to be restricted or not accomplished. [0050] Yeah evident that transmission From Dice in

TCE can be performed directly or indirectly. In some embodiments, the eNB 104 can be configured to communicate directly with the TCE.

In some embodiments, the eNB 104 can be configured to communicate with the TCE via a

In some embodiments, geographic bin performance data can even be sent from the TCE to other network components or can be deposited or stored in any suitable location for future processing such as a historical model.

[0051] According to FIG. 7, a Track Log (TR) 700 message is displayed. A TR 700 message, or other message, can be used to report geographic bin performance data from eNB 104 to the TCE or other network component. It is evident that the TR 700 message may include some or all of the parameters shown in FIG. 7 and may include additional parameters not shown in FIG. 7. In addition, geographic bin performance data can be included as part of another control message designed or designed to support the collection and reporting of geographic bin data, but can also be carried as part of a control message existing and established. As an example, geographic bin performance data may be included as part of the TR 700 message and may or may not be related to other system's Trace Log or Trace Collection features. In these cases, the TR 700 message can carry or input geographic bin performance data “through the horse's door.

Petition 870160051065, of 9/13/2016, p. 38/188

Container 710 may further include any or all of an average number of UEs 102, an average signal strength indicator of UEs 102 in the geographical bin and an average signal quality indicator of UEs 102 in the geographical bin, as indicated by fields 720, 725 and 730, respectively, in FIG. 7.
