Description

Transmission resource configuration method, access device and terminal

Technical Field

The present invention relates to data transmission technologies, and in particular, to a transmission resource configuration method, an access device, and a terminal.

Background

Currently, the International Telecommunications Union (ITU) proposes three broad classes of communication scenarios: the method enhances the mobile broadband communication scene, the massive machine communication scene and the high-reliability low-delay communication scene. In a massive machine communication scene, various terminals with battery modules perform information interaction with a network. In the communication process, in order to save power, the terminal is in a dormant state most of the time, and enters an active state to transmit uplink information only when the service needs to be transmitted.

Generally, a terminal may transmit uplink information in two ways: the method comprises the steps of firstly, transmitting uplink information by adopting resources based on scheduling; and the second mode is that the uplink information is transmitted by adopting the resource based on the competition. In the first mode, when the terminal needs to send the uplink information, the terminal enters the active state from the dormant state, requests the access device to allocate scheduling resources for the terminal, and then transmits the uplink information on the allocated scheduling resources. In this process, multiple information interactions are required to allocate scheduling resources, resulting in large power consumption and transmission delay of the terminal. Compared with the first and second methods, in consideration of the fact that multiple services have multiple data packets, and meanwhile, to combat the fading of the wireless channel between the terminal and the access device, one data packet has multiple modulation and coding methods, the access device allocates one or more orthogonal contention resource blocks of the same or different sizes to the terminal, and notifies the terminal of the allocation, so that the data packets of different sizes or different modulation and coding methods are transmitted on the most suitable contention resource block. In the process, the terminal does not need to send a scheduling request to the access equipment to allocate scheduling resources, so that the conversion delay of the terminal between the dormant state and the activated state and the power consumption of the terminal are reduced to a certain extent.

However, in the second embodiment, when the penetration rate of the terminal is low, for example, when the number of terminals accessing the same access device is small or the traffic of the terminal is small, the access device still allocates a large number of contention resource blocks, which results in low contention resource block utilization and resource waste.

Disclosure of Invention

Embodiments of the present invention provide a transmission resource allocation method, an access device, and a terminal, in which a CBB for transmitting uplink information is divided into one or more sub-CBBs, so that the terminal selects a target sub-CBB from the sub-CBBs to transmit the uplink information, thereby saving contention resources when the permeability of the terminal is low.

In one aspect, the present invention provides a transmission resource allocation method, including:

the access device configures a first CBB set for the terminal, each CBB in the first CBB set is divided into one or more sub-CBBs, and then the access device sends first indication information comprising information of each CBB in the first CBB set and information of each sub-CBB to the terminal, so that the terminal selects a target sub-CBB from the first CBB set according to the first indication information and transmits uplink information.

In the above method, compared with the first CBB that can only transmit one modulation and coding scheme and one fixed size of uplink information, by dividing the first CBB in the first CBB set into one or more sub-CBBs, each CBB or sub-CBB can be used to transmit uplink information of different modulation and coding schemes and different sizes, thereby saving contention resources when the permeability of the terminal is low.

In one possible design, the uplink information may include control information and data information.

In one possible design, after the sending, by the access device, the first indication information to the terminal, the method further includes:

In one possible design, the uplink information includes data information, and the method further includes:

Detailed Description

Currently, in the process of transmitting uplink information by using contention-based resources, an access device determines the number of contention-based resources and the size of each contention-based resource according to a system load, an expected data packet size, channel characteristics, the number of machine users, a past collision situation, and the like, and allocates one modulation and coding scheme to each contention-based resource. Specifically, referring to fig. 1, fig. 1 is a schematic diagram illustrating a configuration of a current contention-based resource. Referring to fig. 1, an access device configures three Contention Based Blocks (CBBs), where the CBB1 has a size of 20 bytes (byte), a modulation and coding scheme of Quadrature Phase Shift Keying (QPSK), and a code rate of 1/3; the size of the CBB2 is 60 bytes, the modulation coding mode is QPSK, and the code rate is 1/2 code rate; the size of the CBB3 is 80 bytes, the modulation coding mode is QPSK, and the code rate is 1/3 code rate.

After configuring the resources based on contention, the access device notifies the terminal of the related information of the resources based on contention by using a control signaling in a semi-static or dynamic manner, including: the size and location of each contention-based resource, the modulation coding scheme, and the minimum power headroom value. And if the power clear value of the terminal is less than the minimum power clear value of a certain contention-based resource, the terminal does not select the contention-based resource to transmit uplink information.

The access device calculates the possibility factor according to the system load, the available resources, the number of the supported terminals, the data size of the terminal and other factors, and sends the possibility factor to the terminal, so that the terminal can feel whether the terminal can transmit the uplink information by using the resource based on competition. Generally, in a light load condition, a terminal has a relatively high possibility of transmitting uplink information using a contention based resource, and in a high load condition, a terminal has a lower possibility of transmitting uplink information using a contention based resource, thereby reducing the possibility of collision.

In the above transmission resource allocation method, it is considered that multiple services have data packets of multiple sizes, and meanwhile, to combat fading of a wireless channel between a terminal and an access device, one data packet has multiple modulation and coding schemes, and the access device allocates one or more orthogonal contention resource blocks of the same or different sizes to the terminal and notifies the terminal, so that the data packets of different sizes or different modulation and coding schemes are transmitted on the most suitable contention resource block. In the process, different data packets and different modulation and coding modes need mutually orthogonal competitive resource blocks, and when the permeability of the terminal is low, the access equipment still distributes a large number of competitive resource blocks, so that the utilization rate of the competitive resource blocks is low, and resource waste is caused.

In view of the above, the present invention provides a transmission resource allocation method, which divides a CBB for transmitting uplink information into one or more sub-CBBs, so that a terminal selects a target sub-CBB from the sub-CBBs to transmit uplink information, thereby saving contention resources when the permeability of the terminal is low.

The techniques described herein may be used in various communication systems, such as current 2G, 3G communication systems and next generation communication systems, such as Global System for Mobile communications (GSM), Code Division Multiple Access (Code Division Multiple Access, CDMA) systems, Time Division Multiple Access (TDMA) systems, Wideband Code Division Multiple Access (WCDMA), Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, FDMA (SC-FDMA) systems, General Packet Radio Service (GPRS, Radio) systems, Long Term Evolution (Long Term Evolution, LTE) systems, and other single carrier communication systems.

The terminal referred to in this application, specifically the terminal supporting contention-based resource transmission uplink information, may be a wireless terminal, which may be a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or other processing device connected to a wireless modem. Wireless terminals, which may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers having mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, may communicate with one or more core networks via a Radio Access Network (e.g., RAN). Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. A wireless Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), a User Device (User Device), or a User Equipment (User Equipment).

The Access device referred to in this application may be a base station, an Access Point (AP), or the like. A base station may refer to a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminals. The base station may be configured to interconvert received air frames and IP packets as a router between the wireless terminal and the rest of the access network, which may include an Internet Protocol (IP) network. The base station may also coordinate management of attributes for the air interface. For example, the Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, or an evolved Node B (NodeB or eNB or e-NodeB) in LTE, which is not limited in this application.

For convenience and clarity of description, the technical solution of the present invention is described in detail below by taking an example that a system architecture is specifically an OFDM system and an example that an access device is specifically a base station. Specifically, please refer to fig. 2.

Fig. 2 is a schematic diagram of a wireless communication system to which the transmission resource allocation method of the present invention is applied. The wireless communication system may be a CDMA based UMTS system or an OFDM based LTE system. As shown in fig. 2, in the embodiment of the present invention, an access device configures a first CBB set for a terminal, divides a first CBB in the first CBB set into one or more sub-CBBs and notifies the terminal, so that the terminal selects an appropriate target sub-CBB from the first CBB set to transmit uplink information. The following describes the notification method of the present invention in detail on the basis of fig. 2.

Fig. 3 is a signaling diagram of a first embodiment of a transmission resource allocation method according to the present invention, where in this embodiment, an access device interacts with a terminal and is suitable for a scenario where the access device allocates transmission resources for the terminal. Specifically, the present embodiment includes the following steps:

101. the access equipment configures a first competition resource block CBB set for the terminal.

Wherein the first CBB set comprises at least one CBB, each CBB is divided into one or more sub-CBBs, and when the first CBB set comprises at least two CBBs, the CBBs are orthogonal to each other. Generally, uplink data is transmitted through a dedicated uplink transmission resource. However, when there is no dedicated uplink transmission resource, Contention resources are required to transmit uplink information, and the resources obtained through Contention are Contention-Based (CB) resources. The CB resources are divided in a time domain and a frequency domain to obtain different resource blocks, which are Contention Based Blocks (CBBs).

In the embodiment of the present invention, the CBBs are orthogonal to each other means that the CBBs do not overlap with each other, for example, for an LTE system based on OFDM, the CBBs are orthogonal to each other, which means that the CBBs do not overlap in the time domain and the frequency domain; for another example, for a CDMA-based UMTS system, the CBBs are orthogonal to each other, which means that the CBBs do not overlap in the time domain and the code domain; for example, in other communication systems, the CBBs may not overlap each other in the spatial domain or the like, or the CBBs may not overlap each other in a single domain or a plurality of combined domains such as the time domain, the frequency domain, the codeword domain, and the spatial domain.

In this step, the access device divides each CBB in the first CBB set into one or more sub-CBBs, and the sub-CBBs may be orthogonal or non-orthogonal to each other. For example, the first CBB set includes 3 CBBs, and each (or part of) CBBs may be partitioned into 2 mutually orthogonal sub-CBBs or non-orthogonal sub-CBBs. In the division process, the division can be performed in a frequency domain orthogonal or non-orthogonal mode, a time domain orthogonal or non-orthogonal mode and the like. Taking the frequency domain division as an example, assuming that one CBB occupies 10 subcarriers in the frequency domain, and the numbers of the subcarriers are 1 to 10, the division process can divide all frequency domain resources of the CBB, that is, all subcarriers, to obtain two sub-CBBs, for example, when the two sub-CBBs occupy subcarriers 1 to 5, 6 to 10, or 1 to 3, 4 to 10, etc. in the time domain, the two sub-CBBs are orthogonal sub-CBBs; for another example, when the two sub-CBBs respectively occupy sub-carriers 1 to 6, 5 to 10, or 1 to 7, 4 to 10, etc. in the frequency domain, the two sub-CBBs are non-orthogonal sub-CBBs; in addition, partial frequency domain resources of the CBB, that is, partial subcarriers, may also be divided to obtain two sub-CBBs, for example, when the two sub-CBBs occupy subcarriers 1 to 4, 5 to 8, or 1 to 5, 7 to 10, etc. in the time domain, the two sub-CBBs are orthogonal sub-CBBs.

102. And the access equipment sends first indication information to the terminal.

The first indication information includes information of each CBB and information of each sub-CBB in the first CBB set, and is used by the terminal to select a target CBB or sub-CBB from the first CBB set according to the first indication information to transmit uplink information.

Specifically, after configuring a first CBB set for a terminal, an access device sends first indication information to the terminal when the terminal accesses and exits, or in each adjustment period, so as to notify the terminal of information of each CBB and information of each sub-CBB in the first CBB set, where the information of each CBB includes a size, a position, a load, and the like of the CBB; the information of each sub-CBB includes the size, location, and load of the sub-CBB, etc. In the notification process, the first indication information may be transmitted by using broadcast, dedicated signaling, or multicast signaling.

For clarity, in the embodiment of the present invention, each CBB in the first CBB set is taken as a first Layer CBB, the first Layer is taken as L1(Layer1), each sub-CBB obtained by dividing the first CBB in the first CBB set is taken as a second Layer sub-CBB, and the second Layer is taken as L2(Layer 2).

103. And the terminal selects a target sub-CBB from the first CBB set according to the first indication information.

Since the first indication information carries information such as the size and the load of each CBB or each sub-CBB, after receiving the first indication information, the terminal may select a sub-CBB capable of transmitting the uplink information according to the size of the uplink information to be uploaded, and when there are a plurality of sub-CBBs, further select a sub-CBB with a lighter load from the plurality of sub-CBBs as a target sub-CBB.

104. And the terminal transmits uplink information through the target sub CBB.

In the above steps 103 and 104, after receiving the first indication information, the terminal selects a suitable target sub-CBB from the first CBB set according to its own capability, service requirement, and the like, to transmit the uplink information.

In steps 103 and 104, after receiving the first indication information, the terminal may select one CBB from the first CBB set to transmit the uplink information.

According to the transmission resource allocation method provided by the embodiment of the invention, the access equipment allocates a first CBB set for the terminal, the CBB in the first CBB set is divided into one or more sub-CBBs, then, the access equipment sends first indication information comprising information of each CBB in the first CBB set and information of each sub-CBB to the terminal, so that the terminal selects a target sub-CBB from the first CBB set according to the first indication information and transmits uplink information, only one modulation coding mode and uplink information with a fixed size can be transmitted compared with the first CBB, and each CBB or sub-CBB can be used for transmitting uplink information with different modulation coding modes and different sizes by dividing the first CBB in the first CBB set into one or more sub-CBBs, so that contention resources are saved when the permeability of the terminal is low.

Generally, the uplink information includes control information and data information. In the embodiment of the present invention, the control information and the data information may be transmitted on the same sub-CBB, and at this time, the control information and the data information may be transmitted on the same contention resource, or the data information may be transmitted on a sub-CBB divided by a certain CBB in the sub-first CBB set, and the control information may be transmitted on a CBB in the second CBB set, and at this time, the control information and the data information may be transmitted on different contention resources. The present invention will be described in detail below in terms of two cases, namely, transmission of control information and data information on the same contention resource, and transmission of control information and data information on different contention resources.

The first case, control information and data information are transmitted on the same contention resource. At this time, in the first embodiment, the uplink information includes control information and data information. In this case, when the control information and the data information are transmitted in the same CBB or sub-CBBs, the control information and the data information may be combined and then encoded or separately encoded and then combined and combined, thereby reducing the complexity of the terminal implementation.

First, initial conditions.

It is assumed that the control information and the data information sent by the terminal may have the same or different modulation and coding schemes, and the control information and the data information of the terminal may be configured as a combined coding scheme or a combined coding scheme after being respectively coded by an indication, and are transmitted on one uplink contention resource, that is, the same sub-CBB. After the control information and the data information sent by the terminal are supposed to be combinedCoding or respectively coding and then combining, wherein the sizes of the required uplink transmission resource blocks are N types in total and are defined as follows: { CBB₁，CBB₂，，，CB_B，，，CBB_NTherein of

For example, CBB₁Can represent 20byte data packet, 1/2 code rate, QPSK modulation; CBB₂Can represent 20byte data packet, 1/3 code rate, QPSK modulation; CBB₃May represent a 40byte packet, 1/2 code rate, QPSK modulation, etc.

Second, the CBB configuration process.

When a terminal initially accesses a network, an access device allocates a first CBB set for the terminal; when the service requirement of the terminal accessed to the network changes or the load of the competitive resource block changes, the access equipment can adjust the first CBB set of the terminal. In the initial allocation or adjustment, the base station configures a first CBB set including one or more orthogonal CBBs for the terminal, and the CBBs may be the same or different in size. Specifically, referring to fig. 4, fig. 4 is a schematic diagram of a first CBB set in the transmission resource allocation method of the present invention. Further, one or more orthogonal or non-orthogonal sub-cbs are divided from the interior of one or more CBBs in the first CBB set, and the sub-cbs have the same or different sizes, specifically, refer to fig. 5A to 5H, where fig. 5A is a schematic diagram of dividing one CBB into two orthogonal sub-CBBs from the time domain in the transmission resource allocation method of the present invention, fig. 5B is a schematic diagram of dividing one CBB into two orthogonal sub-CBBs from the frequency domain in the transmission resource allocation method of the present invention, fig. 5C is a schematic diagram of dividing one CBB into 8 orthogonal sub-CBBs from the time domain and the frequency domain in the transmission resource allocation method of the present invention, fig. 5D is a schematic diagram of dividing one CBB into 4 orthogonal sub-CBBs from the time domain and the frequency domain in the transmission resource allocation method of the present invention, fig. 5E is a schematic diagram of dividing one CBB into two non-orthogonal sub-CBBs from the frequency domain in the transmission resource allocation method of the present invention, fig. 5F is a schematic diagram of dividing a CBB into 4 non-orthogonal sub-CBBs from the frequency domain and the time domain in the transmission resource allocation method of the present invention, and fig. 5G is a schematic diagram of dividing a sub-CBB from a CBB resource in the transmission resource allocation method of the present invention; fig. 5H is a schematic diagram illustrating a transmission resource allocation method according to the present invention, in which partial resources of a CBB are divided.

Referring to FIG. 4, the first CBB set includes L1-CBB1, L1-CBB2 and L1-CBB3, which are orthogonal to each other. The L1-CBB1 is divided, and the sub-CBBs obtained by the division include, but are not limited to, the cases shown in FIGS. 5A to 5F. For example, in FIG. 5A, L1-CBB2 is divided into orthogonal L2-sub-CBB 1 and L2-sub-CBB 2; for another example, in FIG. 5C, L1-CBB2 is divided into orthogonal L2-sub-CBB 1-L2-sub-CBB 8; for another example, in FIG. 5F, L1-CBB2 is divided into non-orthogonal L2-sub-CBB 1-L2-sub-CBB 6.

In the above FIG. 5A to FIG. 5F, the sub CBB is obtained by dividing the resources of the entire L1-CBB 2. However, the present invention is not limited thereto, and in other possible implementations, the partial resources of L1-CBB2 may be divided into orthogonal or non-orthogonal sub-CBBs, which is shown in fig. 5G as non-orthogonal.

In the above fig. 5A to 5G, one L1-CBB2 is divided into a plurality of sub-CBBs, however, the present invention is not limited thereto, and in other possible implementations, only one sub-CBB may be divided into L1-CBB2, as shown in fig. 5H, where the resources of L1-CBB2 are left.

In fig. 4 and 5A to 5F, the CBBs are orthogonal to each other, which means that the CBBs are contention resource blocks orthogonal to each other in at least one of the time domain, the frequency domain, the codeword domain, the space domain, and the like, and similarly, the sub-CBBs are orthogonal to each other, which means that the sub-CBBs are contention resource blocks orthogonal to each other in at least one of the time domain, the frequency domain, the codeword domain, the space domain, and the like. Obviously, since the sub-CBBs of the second layer exist inside the first layer CBB, the sub-CBBs of the second layer are not orthogonal to the CBBs of the first layer to which they belong.

Note that, in fig. 5A to 5H, the sub-CBBs of the second layer are drawn on top of the CBBs of the first layer for clarity of drawing. In practice, however, the sub-CBBs of the second layer are located inside the CBBs of the first layer.

Thirdly, the CBB indicates a procedure that the access device sends the first indication information to the terminal.

The access equipment collects the capability level information of the terminal, wherein the capability level information comprises the size, modulation coding mode, maximum transmission power and the like of a service data packet supported by the terminal, and according to the information, the access equipment configures a first CBB set for the terminal, divides the CBB in the first CBB set into one or more sub-CBBs which are orthogonal or not orthogonal with each other, and then informs the terminal of the information of each CBB and the information of each sub-CBB included in the first CBB set, so that the terminal selects a target sub-CBB in the first CBB set to transmit control information and data information.

Next, the configuration of the first indication information will be described by taking an OFDM-based wireless communication system as an example. The first indication information includes information of each CBB and information of each sub-CBB in the first CBB set. Specifically, the information of each first layer CBB, i.e., each L1-CBB, includes: specifically, refer to fig. 6A, where fig. 6A is an information schematic diagram of L1-CBB in the transmission resource configuration method of the present invention.

Referring to fig. 6A, the starting carrier position, the number of carriers, the frame interval, and the number of continuous frames represent the size and position of the L1-CBB, the frame interval is used to determine the starting frame number of the L1-CBB, the current frame number can be used to modulo the frame interval, and the frame number with the modulo result being a fixed positive integer or 0 can be defined as the starting frame number; if the control information and the data information are jointly encoded, the control information and data information joint modulation encoding mode field in fig. 6A is valid, otherwise, the control information modulation encoding mode and the data information modulation encoding mode are respectively indicated; the number of L2-sub-CBB species is used to characterize how many sizes of L2-sub-CBBs can exist within each L1-CBB, if the number of species is 0, then there is no L2-sub-CBB, at which time the L1-CBB load status field exists; otherwise, it is not present; the load condition indicates the load information of the current L1-CBB, and the load information may be a user number, an error rate, a demodulated Signal to Interference Ratio (SIR), a service arrival rate, and the like.

The information of L1-CBB may indicate that there are many L2-sub-CBBs, and the information of each L2-sub-CBB includes: specifically, refer to fig. 6B, where fig. 6B is an information schematic diagram of L2-sub CBB in the transmission resource allocation method of the present invention.

Referring to fig. 6B, the start carrier position, the number of carriers, the frame interval, and the number of continuous frames represent the size and position of the L2-sub-CBB, the start carrier position is used to determine which L1-CBB the L2-sub-CBB belongs to, in particular, which L1-CBB the start carrier position belongs to, and which L1-CBB the L2-CBB belongs to, in addition to determining the frequency domain real position of the L2-sub-CBB; the number of overlapped carriers exists only if the L2-sub-CBBs are allowed to overlap to "yes" in fig. 6A, which can be used to determine the starting position of the next L2-sub-CBB of the same size, since the above information can calculate how many L2-sub-CBBs of the size and their positions are included in the L1-CBB; if the control information and the data information of the L1-CBB stated in the L2-sub CBB are jointly coded, the control information and the data information joint modulation coding mode domain of the L2-sub CBB is valid, otherwise, the control information modulation coding mode and the data information modulation coding mode of the L2-sub CBB are respectively indicated; the load condition indicates the load information of the current L2-sub CBB, and the load information can be the number of users, the error rate, the demodulated SIR, the service reaching rate and the like.

And finally, carrying out an uplink information transmission process.

The terminal selects the target sub-CBB to send uplink information according to the capability of the terminal, the service requirement and the first indication information sent by the access equipment, the access equipment demodulates at all possible configured CBB positions, and the access equipment can simultaneously demodulate the uplink information transmitted on a plurality of non-orthogonal sub-CBBs by using advanced receivers such as interference cancellation, joint detection and the like. The uplink information includes control information and data information.

Taking an OFDM-based wireless communication system as an example, the content of the control information includes: specifically, refer to fig. 6C, where fig. 6C is a schematic diagram of control information when data information and control information are transmitted on the same transmission resource in the transmission resource configuration method of the present invention.

Referring to fig. 6C, the control information includes the terminal identity and the retransmission times of the data packet.

The access equipment determines that the control information and the data information are respectively coded according to the information whether the control information and the data information are jointly coded; further determining whether to execute hybrid automatic repeat request (HARQ) combination according to the identity and the retransmission times; or, determining whether to execute automatic repeat request ARQ combination according to the identity and the retransmission times.

In addition, the access equipment determines the joint coding of the control information and the data information according to the information about whether the control information and the data information are jointly coded; whether automatic repeat request ARQ combination is executed is further determined according to the identity and the retransmission times.

In the transmission resource configuration method, the control information and the data information are transmitted on the same competition resource, when the permeability of the terminal is low, even if the terminal has multiple capability levels, the capability levels comprise information such as a modulation coding mode, a data packet size and maximum transmission power, the access equipment only needs to allocate fewer competition-based resources to support multiple requirements of the terminal, the competition-based resources are saved, and along with the improvement of the permeability of the terminal, the access equipment can adjust uplink transmission competition resources according to the load information of each competition resource block, so that the utilization rate and the allocation flexibility of the competition-based resources are improved.

The second case, control information and data information are transmitted on different contention resources. At this time, in the first embodiment, the uplink information includes data information. In this case, when the CBB for transmitting the control information and the CBB to which the sub-CCB for transmitting the data information belongs are different, the control information and the data information may independently adopt respective modulation and coding modes, the base station side may adjust and control the loads of the CBB for data information and the CBB for control information, and simultaneously, the base station may be supported to perform HARQ combining and receiving of the CBB for data information, thereby improving the receiving performance of the base station.

First, initial conditions.

It is assumed that the control information and the data information transmitted by the terminal may have the same or different modulation and coding schemes, and the control information and the data information of the terminal are transmitted on different contention resources, respectively. Assuming that the sizes of uplink transmission resource blocks required by control information sent by a terminal share M classes, the definitions are:

wherein

Assuming that the sizes of uplink resource blocks required by data information transmitted by a terminal are N types, the sizes are defined as: { CBB₁，CBB₂，，，CBB_n，，，CBB_NTherein of

Second, the CBB configuration process.

When a terminal initially accesses a network, an access device allocates a first CBB set and a second CBB set for the terminal; when the service requirement of the terminal accessed to the network changes or the load of the competitive resource block changes, the access device adjusts the first CBB set and the second CBB set of the terminal. The first CBB set is used for transmitting data information, the second CBB set is used for transmitting control information, the second CBB set includes at least one CBB, each CCB included in the second CBB set is orthogonal to each CBB included in the first CBB set, and when at least two CBBs are included in the second CBB set, each CBB is orthogonal to each other. Specifically, referring to fig. 7, fig. 7 is a schematic diagram of a first CBB set and a second CBB set in the transmission resource allocation method of the present invention. Where the right superscript d of the CBB represents for data information transmission and the right superscript c represents for control information transmission.

The configuration of the first CBB set has already been done due to the first scenario described aboveThe configuration of the second CBB set is therefore explained in detail here. Specifically, in the initial allocation or adjustment, the base station configures a second CBB set including one or more orthogonal CBBs for the terminal, and the CBBs may be the same or different in size. Referring to FIG. 7, the second CBB set includes

The CBBs in the first CBB set may or may not be mapped one-to-one with the CBBs in the second CBB set, that is, one CBB in the second CBB set may correspond to multiple CBBs in the first CBB set, but the CBBs in the first CBB set are aligned with the corresponding CBBs in the second CBB set in time. For example, in FIG. 7,

can map

Can also map

But cannot map

While

Can only map

In the second case, the CBBs in the first CBB set may be referred to as CBBs for data information, and the CBBs in the second CBB set may be referred to as CBBs for control information.

Thirdly, the CBB indicates a procedure that the access device sends second indication information to the middle terminal.

The access device may adjust the second CBB set when the terminal accesses and exits, or periodically adjust the second CBB set, and notify the adjusted information of each CBB in the second CBB set to the terminal, that is, send the second indication message to the terminal. In the notification process, a second indication message may be sent by using broadcast, dedicated signaling, or multicast signaling, so as to notify the terminal of the information of each CBB included in the second CBB set, so that the terminal selects a target CBB from the second CBB set to transmit the control information.

It should be noted that, in the above embodiment, the first indication message includes information of each CBB in the first CBB set and information of each sub-CBB, and the second indication message includes information of each CBB in the second CBB set. However, in an actual implementation process, the first indication message and the second indication message may be combined into one message and sent to the terminal through broadcasting, dedicated signaling, or the like, at the same time or at different times, so that when the control information and the data information are transmitted on different contention resource blocks, the terminal may select the target sub-CBB to transmit the data information and select the target CBB to transmit the control information.

Next, the configuration of the second instruction information will be described by taking an OFDM-based wireless communication system as an example. The second indication information includes information of each CBB in the second CBB set. Specifically, the information of each CBB in the second CBB set includes: specifically, refer to fig. 8A, where fig. 8A is a schematic diagram of information of each CBB in the second CBB set in the transmission resource allocation method of the present invention.

Referring to fig. 8A, for a specific CBB in the second CBB set, the starting carrier position, the number of carriers, the frame interval, and the number of continuous frames represent the size and position of the CBB, the frame interval is used to determine the starting frame number of the CBB, the current frame number may be used to modulo the frame interval, and the result of the modulo may be defined as a certain fixed positive integer or a frame number of 0 as the starting frame number; the load condition indicates the load information of the CBB, and the load information may be the number of users, the error rate, the demodulated SIR, the service arrival rate, and the like.

And finally, carrying out an uplink information transmission process.

The terminal selects a target sub CBB to send data information according to the capability of the terminal, the service requirement and the first indication information sent by the access equipment; and the terminal selects the target CBB to send the control information according to the capability of the terminal, the service requirement and the second indication information sent by the access equipment.

Taking an OFDM-based wireless communication system as an example, the content of the control information includes: the terminal identity identification, the retransmission times, the CBB initial carrier position of the data information and the CBB carrier number of the data information. Specifically, referring to fig. 8B, fig. 8B is a schematic diagram of control information when data information and control information are transmitted on different transmission resources in the transmission resource allocation method of the present invention.

Referring to fig. 8B, the control information includes the terminal identity, the retransmission times, the CBB start carrier position of the data information, and the CBB carrier number of the data information. The access equipment determines whether to execute hybrid automatic repeat request (HARQ) combination according to the identity and the retransmission times; or, determining whether to execute automatic repeat request ARQ merging according to the identity and the retransmission times; and determining the size and the position of the first CBB according to the initial carrier position of the first CBB and the number of the carriers of the first CBB.

When the data information and the control information are transmitted on different transmission resources, because the CBBs in the first CBB set are aligned with the CBBs in the corresponding second CBB set in time, the information of the CBBs in the CBB set of the control information does not need to carry the position information of the CBBs of the corresponding data information in the time domain, and only needs to carry frequency domain information, that is, the position of the actual carrier of the data information CBB and the number of carriers of the CBBs of the data information CBB.

After the access device sends second indication information to the terminal, demodulating the position of at least one CBB in each CBB in the second CBB set to demodulate the control information, wherein the control information carries the information of the target sub-CBB; and the access equipment demodulates the position of the target sub-CBB according to the information of the target sub-CBB so as to demodulate the data information. Specifically, the access device demodulates the configured positions of all possible control information CBBs to demodulate the content of the corresponding control information, and then demodulates the corresponding data information CBBs at the corresponding positions according to the content of the control information, thereby demodulating the data information. The access device can simultaneously demodulate data information transmitted on a plurality of non-orthogonal sub-CBBs using advanced receivers such as interference cancellation, joint detection, and the like.

In the transmission resource configuration method, the control information and the data information are respectively transmitted on different competition resources, when the permeability of the terminal is low, even if the terminal has multiple capability levels, the capability levels comprise information such as a modulation coding mode, a data packet size and maximum transmission power supported by the terminal, the access equipment only needs to allocate fewer competition-based resources to support multiple requirements of the terminal, so that the competition-based resources are saved, and along with the improvement of the permeability of the terminal, the access equipment can adjust uplink transmission competition resources according to the load information of each competition resource block, so that the utilization rate and the allocation flexibility of the competition-based resources are improved. Meanwhile, the access device analyzes the load of the control information and the load of the data information respectively, and the load of the control information and the load of the data information can be adjusted independently by setting different load thresholds. Compared with the situation that the data information and the control information are transmitted on the same transmission resource, the method has better flexibility, can improve the overall demodulation performance of the control information and the data information, and improves the resource utilization rate.

In the first case, the first CBB set configured by the access device for the terminal is not a uniform but may be adjustable; similarly, in the second case, the second set of CBBs may also be adjusted. Specifically, referring to fig. 9, fig. 9 is a schematic diagram of an adjustment process of a CBB in the transmission resource allocation method of the present invention, including:

201. and the access equipment distributes or adjusts the CBB set according to the service requirement and the load condition of the terminal.

The access equipment periodically performs statistical analysis on the load information of each CBB and each sub-CBB in the CBB set, wherein the load information comprises the number of users, the error rate, the demodulated SIR, the service achievement rate and the like. Based on the information, the access device adjusts the CBB set.

202. The access device informs the information of each CBB and each sub-CBB in the CBB set of the terminal through broadcasting, multicasting or special signaling.

Specifically, the access device notifies the terminal of information of each CBB, information of each sub-CBB, load information, and the like in the adjusted CBB set, and the terminal selects a target sub-CBB in the adjusted CBB set to transmit uplink information. For example, the access device may adjust the CBB set when the terminal accesses and exits, or periodically adjust the CBB set, and notify the information of each CBB and each sub-CBB in the adjusted CBB set to the terminal.

203. And the access equipment analyzes and counts the load condition of each CBB in the CBB set and the load condition of each sub CBB.

In this step, the access device analyzes the load status of each CBB and the load status of each sub-CBB in the CBB set, and returns to 201 to form a closed-loop process.

In steps 201 to 203, the CBB set may refer to a first CBB set, may refer to a second CBB set, and may also include both the first CBB set and the second CBB set, where for the first CBB set, closed-loop adjustment is performed according to the load conditions of the sub-CBBs in the set, and for the second CBB set, closed-loop adjustment is performed according to the load conditions of the sub-CBBs in the set.

The present invention has been described in detail above from the perspective of resource configuration. The present invention is described in detail below from the perspective of data transmission and the perspective of transmission resource indication, respectively.

First, the angle of data transmission.

Specifically, the access device receives uplink information sent by a terminal through a target sub-CBB, where the target sub-CBB is selected by the terminal from a first CBB set, the CBBs included in the first CBB set are orthogonal to each other, and each CBB is divided into one or more sub-CBBs; and demodulating the position of each sub CBB in the first CBB set to demodulate the uplink information.

When the control information and the data information are transmitted in the same CBB, the terminal selects a target sub-CBB from the first CBB set according to the capability of the terminal, the service requirement and the first indication information sent by the base station to send the data information and the control information; the access network equipment demodulates the position of all possible sub-CBBs in the configured first CBB set to demodulate control information and data information, and the access network equipment can also simultaneously demodulate data transmission on a plurality of non-orthogonal CBBs by using advanced receivers such as interference cancellation and joint detection, and perform HARQ (hybrid automatic repeat request) combination or non-combination. In the process, before receiving uplink information sent by a terminal through a target sub-CBB, the access equipment also configures the first CBB set for the terminal; and sending first indication information to the terminal, wherein the first indication information comprises information of each CBB and information of each sub-CBB in the first CBB set, and is used for enabling the terminal to select the target sub-CBB from the first CBB set according to the first indication information so as to transmit the control information and the data information.

When the control information and the data information are transmitted in different CBBs, the terminal selects a target CBB from the second CBB set to transmit the control information according to the capability of the terminal, the service requirement and the second indication information transmitted by the base station, and selects a target sub-CBB from the first CBB set to transmit the data information according to the capability of the terminal, the service requirement and the first indication information transmitted by the base station. And the access network equipment demodulates at the positions of all the possible second CBBs configured so as to demodulate the control information, and demodulates at the position of the target sub-CBB according to the control information so as to demodulate the data information. The access network device may also simultaneously demodulate data transmissions on multiple non-orthogonal CBBs using advanced receivers such as interference cancellation, joint detection, and the like, and perform HARQ combining or non-combining. In the process, the access equipment configures the second CBB set for the terminal; sending second indication information to the terminal, wherein the second indication information comprises information of each CBB in the second CBB set, and is used for enabling the terminal to select the target CBB from the second CBB set according to the first indication information so as to transmit the control information; then, receiving control information sent by the terminal through a target CBB, wherein the target CBB is selected by the terminal from a second CBB set, and CBBs included in the second CBB set are mutually orthogonal; demodulating a position of each of the CBBs in the second set of CBBs to demodulate the control information.

Optionally, in the foregoing embodiment, the CBBs are orthogonal to each other, and include at least one of the following cases: time domain orthogonality, frequency domain orthogonality, code domain orthogonality and space domain orthogonality.

Optionally, in the above embodiment, each of the sub-CBBs is orthogonal or non-orthogonal to each other.

Optionally, in the foregoing embodiment, the first CBB set configured by the access device for the terminal is not a uniform set, but may be adjustable; similarly, in the second case, the second set of CBBs may also be adjusted. Specifically, the access device determines a load of each CBB and a load of each sub-CBB in the first CBB set; and adjusting the first CBB set according to the load of each CBB in the first CBB set and the load of each sub CBB.
