Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method and apparatus for resource allocation. Background Technology

[0002] Currently, with the continuous emergence of various new business and application demands, the performance requirements of terminal direct communication (also known as sidelink, SL) will become increasingly higher in terms of transmission bandwidth, communication speed range, communication latency, reliability, and scalability. If we rely solely on the limited licensed spectrum of operators, we cannot meet the potential diverse application scenarios and demands in the future. Therefore, it is necessary to study terminal sidelink-unlicensed (SL-U) technology that can be applied to unlicensed frequency bands.

[0003] On unlicensed frequency bands, the OCB (Occupied Channel Bandwidth) requirement must be met, meaning that each transmission must occupy 80% of the bandwidth of each LBT (Listen before Talk) subband (e.g., 20MHz).

[0004] However, there is currently no effective means to configure resource pools on LBT subbands in the SL-U system. Summary of the Invention

[0005] This application provides a resource allocation method and apparatus that can be applied to vehicle-to-everything (V2X) communication, long term evolution-vehicle (LTE-V) communication, and vehicle-to-vehicle (V2V) communication. It can also be used in fields such as intelligent driving and intelligent connected vehicles. By designing a mapping method between the resource pool and the IRB index of the comb-scale resource block, the resource pool resources can be configured. This can meet the OCB requirements on the unlicensed frequency band of the terminal-side travel link, thereby meeting the potential diverse application scenarios and needs in the future.

[0009] In this technical solution, the comb ruler resource block is divided into one or more resource pools to form configuration information for each resource pool. The configuration information for each resource pool indicates the number and location of the comb ruler resource block indexes configured within that resource pool.

[0079] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0080] Currently, with the continuous emergence of various new business and application demands, the performance requirements of terminal direct communication (also known as sidelink, SL) will become increasingly higher in terms of transmission bandwidth, communication speed range, communication latency, reliability, and scalability. If we rely solely on the limited licensed spectrum of operators, we cannot meet the potential diverse application scenarios and demands in the future. Therefore, it is necessary to study terminal sidelink-unlicensed (SL-U) technology that can be applied to unlicensed frequency bands.

[0081] On unlicensed frequency bands, the OCB (Occupied Channel Bandwidth) requirement must be met, meaning that each transmission must occupy 80% of the bandwidth of each LBT (Listen before Talk) subband (e.g., 20MHz). The SL-U system includes the following two resource allocation methods:

[0082] The first method is a resource allocation method that uses comb-scale resource blocks (also called interlaced resource blocks, IRBs) as the granularity. In order to satisfy OCB, a mapping relationship between the resource pool and the IRB index needs to be designed.

[0083] The second approach is a resource allocation method based on sub-channels. This requires defining resource pools on the LBT subbands and designing a mapping relationship between resource pools and IRB indices. Within the IRB indices mapped to the resource pools, the mapping between sub-channels and IRB indices is determined. Therefore, to meet OCB requirements, a mapping between resource pools and IRB indices needs to be designed to achieve resource pool allocation. However, regardless of whether the first or second resource allocation method is used in the SL-U system, there is currently a lack of effective means to configure resource pools on the LBT subbands.

[0084] To this end, this application proposes a resource allocation method and apparatus that can be applied to the SL-U system. By providing a mapping method between a resource pool and a comb ruler resource block index, the resource pool can be allocated. This method can meet the OCB requirements on the unlicensed frequency band of the terminal-side walkway, thereby meeting the potential diverse application scenarios and needs in the future.

[0085] To better understand the resource allocation method and apparatus disclosed in the embodiments of this application, the communication system used in the embodiments of this application will be described first.

[0086] Please see Figure 1 , Figure 1 This application provides a schematic diagram of the architecture of a communication system. The communication system may include, but is not limited to, a network device and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and constitute a limitation on the embodiments of this application. In actual applications, they may include two or more network devices and two or more terminal devices.

[0087] It should be noted that the technical solutions of this application embodiment can be applied to various communication systems. For example, long term evolution (LTE) systems, 5th generation (5G) mobile communication systems, 5G new radio (NR) systems, SL-U systems, or other future new mobile communication systems, etc.

[0088] The network device 101 in this application embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of this application do not limit the specific technology or device form used in the network device. The network device provided in this application embodiment can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure, the protocol layer of the network device, such as a base station, can be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining part or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0089] In this application's embodiments, the terminal device is a user-side entity used to receive or transmit signals, such as a mobile phone.

The embodiments of this application do not limit the specific technology or device form used in the terminal devices.

[0090] It is understood that the communication system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0091] The method and apparatus for resource allocation provided in this application will now be described in detail with reference to the accompanying drawings.

[0092] Please see Figure 2 , Figure 2 This is a flowchart illustrating a resource configuration method provided in an embodiment of this application. It should be noted that the resource configuration method of this embodiment can be applied to unlicensed frequency band systems on the terminal side, and this method can be executed by a network device. Figure 2 As shown, the method for configuring this resource may include, but is not limited to, the following steps.

[0093] In step 201, the comb resource block is mapped to at least one resource pool.

[0094] In the embodiments of this application, the configuration information of each resource pool indicates the number and position of the comb-scale resource block indexes configured for the corresponding resource pool; the resource block value between two consecutive comb-scale resource blocks in the same comb-scale resource block index is M, and M is determined by the size of the subcarrier interval.

[0095] It should be noted that the NR-U system introduces comb-scale resource blocks (also called interlaced resource blocks, IRBs). These are two consecutive comb-scale resource blocks spaced M resource blocks apart. For a comb-scale resource block index m, its included physical resource blocks (PRBs) are {m, M+m, 2M+m, 3M+m, ...}, where m ∈ {0, 1, ..., M-1}. In the NR-U system, IRB structures are defined for 15kHz and 30kHz subcarrier spacings, as shown in the table below.

[0096] Table 4.4.4.6-1: Number of resource block interleavings

[0097] μ M 0 10 1 5

[0098] For example, such as Figure 3 As shown, when the subcarrier spacing SCS = 30kHz and M = 5, there are a total of 5 comb ruler resource block indices. For a single comb ruler resource block index, such as comb ruler resource block index 0, the comb ruler resource block index contains the comb ruler resource block PRB{0,5,10,15,20,25,30,35,40,45}. For example, ... Figure 4As shown, when the subcarrier spacing SCS = 15kHz and M = 10, there are 10 comb ruler resource block indices and a total of 100 PRBs. For each comb ruler resource block index, such as index 0, the comb ruler resource block index contains PRBs {0, 10, 20, 30, 40, 50, 60, 70, 80, 90}. This application further introduces comb ruler resource blocks, thereby reducing the overhead of frequency domain resources specified in the configuration instructions in the SL-U system.

[0099] In embodiments of this application, when configuring resource pools, network devices can map comb ruler resource blocks in the system to one or more resource pools. As an example, comb ruler resource blocks can be mapped to one or more resource pools based on a mapping rule between resource pools and comb ruler resource block indexes. This mapping rule can be agreed upon by a protocol.

[0100] In step 202, the configuration information of each resource pool in at least one resource pool is determined.

[0101] In the embodiments of this application, when configuring resource pools, network devices can map the comb resource blocks in the system to one or more resource pools. That is, the comb resource blocks in the system can be divided into one or more resource pools to form system resource pool configuration information. This resource pool configuration information includes the configuration information of each resource pool. The configuration information of each resource pool indicates the number and location of the comb resource block indexes configured in the corresponding resource pool, thereby realizing resource pool resource configuration. Optionally, each resource pool can correspond to a unique resource pool index number, which indicates the use of the comb resource blocks contained in the corresponding resource pool to carry the control information and / or data information of the terminal device.

[0102] By implementing the embodiments of this application, the comb ruler resource block is divided into one or more resource pools to form configuration information for each resource pool. The configuration information for each resource pool indicates the number and location of the comb ruler resource block indexes configured in the corresponding resource pool. Therefore, this application provides a mapping method between resource pools and comb ruler resource block indexes to achieve resource pool resource configuration. This can meet the OCB requirements on the terminal-side unlicensed downlink frequency band, thereby satisfying potential diverse application scenarios and needs in the future.

[0103] To implement the above embodiments, this application also provides another method for resource allocation. In some embodiments of this application, such as... Figure 5 As shown, the method for configuring this resource may include, but is not limited to, the following steps.

[0104] In step 501, the number of comb-ruler resource block indexes and the location of the comb-ruler resource block indexes in a resource pool are determined according to the mapping rules between the resource pool and the comb-ruler resource block indexes.

[0105] It is understood that in the embodiments of this application, the mapping rule between the resource pool and the comb ruler resource block index can be agreed upon by a protocol. For example, the mapping rule between the resource pool and the comb ruler resource block index can be agreed upon by a protocol. In this way, the number of comb ruler resource block indexes contained in a resource pool and the location of the comb ruler resource block indexes can be determined according to the mapping rule between the resource pool and the comb ruler resource block index, so as to use the mapping rule to determine the configuration information of the resource pool configured by the network device.

[0106] In step 502, based on the number and location of the comb ruler resource block indexes contained in a resource pool, the comb ruler resource blocks are mapped to at least one resource pool, and the configuration information of each resource pool in the at least one resource pool is determined.

[0107] In other words, the system's comb ruler resource blocks can be mapped to at least one resource pool based on the number and location of the comb ruler resource block indexes that a resource pool should contain. This allows the configuration information of the resource pool configured by the network device to be determined, which indicates the number and location of the comb ruler resource block indexes configured for the corresponding resource pool.

[0108] It should be noted that, in the embodiments of this application, one resource pool can be mapped to one LBT sub-band, or one resource pool can be mapped to multiple LBT sub-bands. Different mapping methods correspond to different mapping rules. The mapping rules between the resource pool and the comb ruler resource block index will be described below in conjunction with the embodiments of mapping one resource pool to one LBT sub-band and mapping one resource pool to multiple LBT sub-bands, respectively.

[0109] For the case where one resource pool is mapped to one LBT subband:

[0110] In one implementation, the mapping rule between the resource pool and the comb block index is as follows: a resource pool is mapped to N1 consecutive or non-consecutive comb block indices in a Listen-The-After-Speak LBT subband; where N1 is a positive integer less than or equal to M.

[0111] In other words, when one resource pool is mapped to one LBT subband, within one LBT subband, one resource pool can be mapped to N1 consecutive or non-consecutive comb ruler resource block indices, where 1≤N1≤M.

[0112] Optionally, the implementation of mapping a resource pool to a consecutive or non-consecutive integer N1 comb block indexes in a Listen-After-Speak LBT subband can be as follows: starting from the first comb block index in an LBT subband, the consecutive or non-consecutive integer N1 IRB indices are mapped to the corresponding resource pools according to the logical number of the comb block index; where N1 is less than M.

[0113] For example, when 1 ≤ N1 < M, when mapping a resource pool to a comb ruler resource block index, the resource pool can start from the first comb ruler resource block index in the first LBT sub-band and map consecutive or non-consecutive integers N1 IRB indices to the corresponding resource pools according to the logical number of the comb ruler resource block index. For instance, when mapping a resource pool to a comb ruler resource block index, the resource pool can start mapping from the comb ruler resource block index with sequence number 0 in the first LBT sub-band and map consecutive or non-consecutive integers N1 IRB indices to the corresponding resource pools according to the logical number of the comb ruler resource block index.

[0114] As an example, taking an LBT subband with a subcarrier spacing SCS = 15kHz, M = 10, and N1 = 8 (N1 < M), the mapping rule between the resource pool and the comb ruler resource block index can be understood as follows: one resource pool is mapped to eight consecutive or non-consecutive comb ruler resource block indices in one LBT subband. For example, one resource pool can be mapped to comb ruler resource block indices numbered 0 to 7 in one LBT subband, meaning one resource pool can be mapped to eight consecutive comb ruler resource block indices in one LBT subband; another example is that one resource pool can be mapped to eight non-consecutive comb ruler resource block indices in one LBT subband, such as indices numbered 0, 1, 2, 3, 5, 6, 7, and 8. For example, taking two resource pools (including resource pool 0 and resource pool 1) as an example, resource pool 0 is mapped to the comb ruler resource block index with the sequence number 0 to 7 in the first LBT sub-band (such as sub-band 0), and resource pool 1 is mapped to the comb ruler resource block index with the sequence number 0 to 7 in the second LBT sub-band (such as sub-band 1). That is, one resource pool is mapped to N1 consecutive comb ruler resource block indices in one LBT sub-band.

[0115] In this embodiment, when mapping resource pools to comb ruler resource block indexes using the mapping rules between the resource pools and the comb ruler resource block indexes, a bitmap can be used for indication. In one implementation, the configuration information of each resource pool is in the form of a bitmap, the length of which is M. Each bit in the bitmap corresponds to a comb ruler resource block index. A bit value of 1 in the bitmap indicates mapping to the corresponding resource pool, and a bit value of 0 in the bitmap indicates not mapping to the corresponding resource pool.

[0116] For example, a bitmap can be used to indicate 10 comb block indices in an LBT subband. Each bit in the bitmap corresponds to a comb block index. A bit value of 1 indicates that the corresponding comb block index is mapped to that resource pool, while a bit value of 0 indicates that the corresponding comb block index is not mapped to that resource pool. It should be noted that the least significant bit of the bitmap corresponds to the comb block index with sequence number 0 in the LBT subband. For instance, if a resource pool is mapped to 5 non-contiguous comb block indices in an LBT subband, and the bitmap is 0101010101, then comb block indices 1, 3, 5, 7, and 9 are mapped to that resource pool.

[0117] In this embodiment, when a resource pool can map consecutive comb ruler resource block indices, the mapping can be indicated by the starting comb ruler resource block index and the number of consecutive comb ruler resource block indices. In one implementation, the mapping rule between the resource pool and the comb ruler resource block index is as follows: a resource pool is mapped to N1 consecutive integer comb ruler resource block indices in an LBT subband; wherein, the configuration information of each resource pool includes indication information for indicating the starting comb ruler resource block index and the number of consecutive comb ruler resource block indices configured for the corresponding resource pool.

[0118] In other words, when the mapping rule between resource pools and comb ruler resource block indices is that a resource pool is mapped to N1 consecutive integer comb ruler resource block indices in an LBT subband, the configuration information of the resource pools configured by the network device can include indication information indicating the starting comb ruler resource block index and the number of consecutive comb ruler resource block indices configured for the corresponding resource pool. Thus, the resource pool configuration can be indicated through this indication method.

[0119] In one implementation, a resource pool includes X sub-channels, where X is a positive integer. The implementation of mapping the resource pool to N1 consecutive or non-consecutive comb ruler resource block indices in a Listen-After-Speak LBT subband can be as follows: X sub-channels in a resource pool are mapped to N1 comb ruler resource block indices, wherein the mapping rule between sub-channels and comb ruler resource block indices is: starting with the first comb ruler resource block index mapped by a resource pool, N1 comb ruler resource block indices are mapped to sub-channels in a resource pool according to the logical number of the comb ruler resource block index.

[0120] For example, if a resource pool is mapped to only a portion of the comb ruler resource block indices in one LBT subband, the mapping of X subchannels in the resource pool to the comb ruler resource block indices can be as follows: X subchannels are mapped to N1 comb ruler resource block indices, and the mapping starts with the first comb ruler resource block index mapped to the resource pool, and is mapped to the subchannels in the resource pool according to the logical number of the comb ruler resource block index. As an example, if a resource pool contains 2 subchannels, and these 2 subchannels are mapped to 12 comb ruler resource block indices, the 12 comb ruler resource block indices start from the comb ruler resource block index with sequence number 0 in the first LBT subband (e.g., IRB index 0), and are mapped according to the logical number of the comb ruler resource block index. Subchannel 0 is mapped to logical numbers comb ruler resource block indices 0 to 5, and subchannel 1 is mapped to logical numbers comb ruler resource block indices 6 to 11.

[0121] Optionally, the implementation of mapping a resource pool to a consecutive or non-consecutive integer N1 comb ruler resource block indices in a Listen-After-Speak LBT subband can be as follows: a resource pool is mapped to M IRB indices in an LBT subband; where N1 equals M. That is, when N1 equals M, when mapping a resource pool to comb ruler resource block indices, one resource pool can be mapped to all M comb ruler resource block indices in one LBT subband.

[0122] In one implementation, the mapping rule between the resource pool and the comb ruler resource block index is as follows: a resource pool is mapped to N2 consecutive or non-consecutive comb ruler resource block indices in an LBT subband; where N2 is a non-integer greater than 1 and less than M.

[0123] It should be noted that, optionally, during resource pool mapping, starting from the first comb ruler resource block index in an LBT subband, N2 consecutive or non-consecutive comb ruler resource block indices can be mapped to the corresponding resource pool one by one according to the logical number of the comb ruler resource block index. The N2 comb ruler resource block indices include: the first comb ruler resource block index to the Lth comb ruler resource block index, and l comb ruler resource blocks in the (L+1)th comb ruler resource block index; L is the integer obtained by rounding down N2, and the value of l is based on the relationship between the decimal part of N2 and M. That is, the value of l can be determined by the relationship between the decimal part of N2 and M. For example, if M = 10 and N2 = 2.5, then the value of l is 5; if M = 5 and N2 = 2.5, then the value of l is 2; and if M = 10 and N2 = 2.3, then the value of l is 3.

[0124] For example, during resource pool mapping, the mapping can begin with the first comb ruler resource block index in the first LBT subband, such as starting with the comb ruler resource block index with sequence number 0 in the first LBT subband. The N2 consecutive or non-consecutive comb ruler resource block indices are mapped to their corresponding resource pools according to their logical numbers. For instance, with N2 = 2.5, one resource pool is mapped to 2.5 consecutive comb ruler resource block indices, such as comb ruler resource block indices 0, 1, and 2. This resource pool can be mapped to the comb ruler resource block index with sequence number 0, the comb ruler resource block index with sequence number 1, and a portion of the comb ruler resource blocks in the comb ruler resource block index with sequence number 2. For example, in the comb ruler resource block index with sequence number 2, this resource pool only maps to the 5 comb ruler resource blocks in that index. The five comb ruler resource blocks can be the first five comb ruler resource blocks in the comb ruler resource block index with the sequence number 2, or the five comb ruler resource blocks can be the five comb ruler resource blocks with odd-numbered sequences in the comb ruler resource block index with the sequence number 2, or the five comb ruler resource blocks can be the five comb ruler resource blocks with even-numbered sequences in the comb ruler resource block index with the sequence number 2. The specific choice can be determined based on the actual application, and no specific limitation is made.

[0125] In one implementation, a resource pool includes X sub-channels, where X is a positive integer. The implementation of mapping a resource pool to N2 consecutive or non-consecutive comb ruler resource block indices in an LBT subband can be as follows: X sub-channels in a resource pool are mapped to N2 comb ruler resource block indices, wherein the mapping rule between sub-channels and comb ruler resource block indices is: starting from the first comb ruler resource block index mapped by a resource pool, N2 comb ruler resource block indices are mapped to sub-channels in a resource pool according to the logical number of the comb ruler resource block index.

[0126] For example, if a resource pool is mapped to only N2 comb ruler resource block indices in a portion of an LBT subband, the mapping of X sub-channels in the resource pool to the comb ruler resource block indices can be as follows: X sub-channels are mapped to N2 comb ruler resource block indices, and the mapping of sub-channels to comb ruler resource block indices starts with the first comb ruler resource block index mapped by the resource pool, and is mapped to the sub-channels in the resource pool according to the logical number of the comb ruler resource block index.

[0127] As an example, consider a resource pool containing two sub-channels, which are mapped to 12.5 comb ruler resource block indices. The 12.5 comb ruler resource block indices start from the comb ruler resource block index with sequence number 0 in the first LBT subband (e.g., IRBindex 0), and are mapped according to the logical number of the comb ruler resource block index. Sub-channel 0 is mapped to logical numbers comb ruler resource block indices 0 to 5, and sub-channel 1 is mapped to logical numbers comb ruler resource block indices 6 to 11. Sub-channel 1 is also mapped to 5 comb ruler resource blocks in logical number comb ruler resource block index 12.

[0128] For the case where one resource pool is mapped to multiple LBT subbands:

[0129] In one implementation, the mapping rule between the resource pool and the comb ruler resource block index is as follows: one resource pool is mapped to N3 comb ruler resource block indices in multiple LBT subbands; where N3 is an integer greater than M, and one resource pool is mapped to comb ruler resource block indices with the same sequence number in each LBT subband, either consecutively or non-consecutively.

[0130] For example, one resource pool is mapped to N comb ruler resource block indices. This one resource pool is mapped to comb ruler resource block indices with the same sequence number in each LBT subband, either consecutively or non-consecutively. As an example, if one resource pool needs to be mapped to 16 comb ruler resource block indices, then the resource pool can be mapped to the 8 comb ruler resource block indices with sequence numbers 0 to 7 in subband 0, and then further mapped to the 8 comb ruler resource block indices with sequence numbers 0 to 7 in subband 1.

[0131] Optionally, the configuration information for each resource pool includes subband indication information and comb ruler resource block index indication information. The subband indication information indicates the multiple LBT subbands mapped to the corresponding resource pool, and the comb ruler resource block index indication information indicates the comb ruler resource block index mapped to the corresponding resource pool in each LBT subband. That is, when the mapping rule between the resource pool and the comb ruler resource block index is: if a resource pool is mapped consecutively or non-consecutively to the same sequence number of comb ruler resource block index in each LBT subband, the configuration information of the resource pool configured by the network device can include subband indication information and comb ruler resource block index indication information. The subband indication information and the comb ruler resource block index indication information can be encoded independently, or they can be jointly encoded.

[0132] In one implementation, the mapping rule between the resource pool and the comb ruler resource block index is as follows: one resource pool is mapped to N3 comb ruler resource block indices in multiple LBT subbands; where N3 is an integer greater than M, and the comb ruler resource block index number mapped by one resource pool is different in each LBT subband.

[0133] In other words, one resource pool can be mapped to N3 comb block indices in multiple LBT subbands. The comb block index number mapped by one resource pool is different in each LBT subband and is configured independently. The configuration methods are as follows:

[0134] Method 1: One resource pool is mapped to N3 comb ruler resource block indices. The comb ruler resource blocks in the subbands are numbered according to their frequency position. For example, the physical numbers of the comb ruler resource blocks in subband 0 with the lowest starting frequency are 0-9, and the logical numbers are 0-9; the physical numbers of the comb ruler resource blocks in subband 1 with the second lowest starting frequency are 0-9, and the logical numbers are 10-19, and so on. During (pre)configuration, the logical numbers of the comb ruler resource blocks mapped to the resource pool are indicated. Based on this configuration method, the configuration information of the resource pool configured by the network device can include indication information, which is used to indicate the logical number of the comb ruler resource block index mapped to the corresponding resource pool.

[0135] For example, such as Figure 6 As shown, N3 = 12, one resource pool is mapped to 12 comb ruler resource block indices. For resource pool 0, it is mapped to the first LBT subband (e.g., Figure 6 In the sub-band 0), the index of the comb ruler resource block with sequence number 0-9 is mapped to the second LBT sub-band (e.g., Figure 6 In subband 1), the two comb block indexes with logical numbers 10-11 are located on the two comb block indexes with physical numbers 0-1 in the second LBT subband.

[0136] Method 2: First, indicate the subband mapped to the resource pool, then indicate the comb ruler resource block index mapped to the corresponding subband. In this example, the configuration information for each resource pool includes subband indication information and comb ruler resource block index indication information. The subband indication information is used to indicate the multiple LBT subbands mapped to the corresponding resource pool, and the comb ruler resource block index indication information is used to indicate the comb ruler resource block index mapped by the corresponding resource pool in each LBT subband.

[0137] In other words, when a resource pool maps different comb ruler resource block index numbers in each LBT subband, two indicator fields can be used to indicate the number and location of the comb ruler resource block indexes configured for the corresponding resource pool. For example, the configuration information of each resource pool includes subband indicator information and comb ruler resource block index indicator information. The subband indicator information is used to indicate the multiple LBT subbands mapped by the corresponding resource pool, and the comb ruler resource block index indicator information is used to indicate the comb ruler resource block indexes mapped by the corresponding resource pool in each LBT subband.

[0138] It should be noted that, in some embodiments of this application, the resource pool configuration information for mapping comb resource blocks in the system to multiple resource pools needs to be communicated to the terminal devices of the system through a certain method. The resource pool configuration information configured by the network device is public information and should be known to all available terminal devices. It can be indicated using system predefined methods, system broadcast messages, or higher-level signaling, such as radio resource control messages. The network device or a terminal device with the authority to send resource pool configuration information can indicate the adopted resource pool configuration through corresponding signaling.

[0139] By implementing the embodiments of this application, the resource pool is configured using the predefined mapping rules between the resource pool and the comb-ruler resource block index. This allows the determination of the number and location of the comb-ruler resource block indexes contained in a resource pool. The resource pool can then be configured using these mapping rules, which can meet the OCB requirements on the unlicensed SL-U band of the terminal-side downlink. This will satisfy the potential diverse application scenarios and needs in the future.

[0140] It is understood that the above embodiments describe the implementation of the resource configuration method of this application from the network device side. This application also proposes a resource configuration method, which will be described below from the terminal device side. Please refer to... Figure 7 , Figure 7 This is a flowchart illustrating another resource allocation method provided in this application. It should be noted that the resource allocation method in this application can be applied to unlicensed frequency bands on the downlink side of the terminal device and can be executed by the terminal device. Figure 7 As shown, the method for configuring this resource may include, but is not limited to, the following steps.

[0141] In step 701, the configuration information of the resource pool sent by the network device is received.

[0142] In the embodiments of this application, the configuration information of the resource pool indicates the number and position of the comb-scale resource block indexes configured for the corresponding resource pool; the resource block value between two consecutive comb-scale resource blocks in the same comb-scale resource block index is defined as M, and M is determined by the size of the subcarrier interval.

[0143] The network device needs to notify the terminal devices of the system of the resource pool configuration information, which maps the comb resource blocks in the system to multiple resource pools, through a certain method. Optionally, based on the resource pool configuration, the network device can indicate the scheduled resource pool resources to the sending UE and / or receiving UE by indicating the resource pool index, which are used to carry the UE's control information and / or data information. The UE can also select one or more resource pools on the available resource pool resources for carrying and transmitting control information and / or data information.

[0144] Optionally, in the embodiments of this application, when a terminal device accesses a network device, it can receive configuration information of a resource pool sent by the network device. Based on the configuration information of the resource pool and the mapping rules between the resource pool and the comb block index, the number and location of the comb block indexes configured in the resource pool scheduled by the terminal device can be determined. For a description of the mapping rules between the resource pool and the comb block index, please refer to the preceding description of the mapping rules, which will not be repeated here.

[0145] By implementing the embodiments of this application, a mapping method between a resource pool and a comb block index is provided to realize the resource configuration of the resource pool. This can meet the OCB requirements on the unlicensed frequency band of the terminal-side walkway, thereby meeting the potential diverse application scenarios and needs in the future.

Figure 8 The communication device 80 shown may include a transceiver module 801 and a processing module 802. The transceiver module 801 may include a sending module and / or a receiving module. The sending module is used to implement the sending function, and the receiving module is used to implement the receiving function. The transceiver module 801 can implement both sending and / or receiving functions.

[0150] In one implementation, the processing module 802 includes a determining unit and a mapping unit. The determining unit is used to determine the number and location of comb-ruler resource block indexes contained in a resource pool according to the mapping rules between resource pools and comb-ruler resource block indexes. The mapping unit is used to map comb-ruler resource blocks to at least one resource pool according to the number and location of comb-ruler resource block indexes contained in a resource pool.

[0153] In one possible implementation, the configuration information for each resource pool includes a bitmap of length M, wherein each bit in the bitmap corresponds to a comb resource block index, and a bit value of 1 in the bitmap indicates mapping to the corresponding resource pool, while a bit value of 0 in the bitmap indicates not mapping to the corresponding resource pool.

[0154] In one possible implementation, the determining unit is specifically used to: determine a resource pool mapped to a consecutive integer N1 comb block indexes in an LBT subband; wherein the configuration information of each resource pool includes indication information for indicating the starting comb block index and the number of consecutive comb block indexes configured for the corresponding resource pool.

[0156] In one possible implementation, the determining unit is specifically used to: determine a resource pool mapped to M IRB indices in an LBT subband; where N1 equals M.

[0157] In one possible implementation, the determining unit is specifically used to: determine a resource pool mapped to N2 consecutive or non-consecutive comb block indices in an LBT subband; wherein N2 is a non-integer greater than 1 and less than M.

[0158] In one possible implementation, the determining unit is specifically used to: starting from the first comb ruler resource block index in an LBT subband, map consecutive or non-consecutive N2 comb ruler resource block indices to the corresponding resource pools according to the logical number of the comb ruler resource block index; wherein, the N2 comb ruler resource block indices include: the first comb ruler resource block index to the Lth comb ruler resource block index, and l comb ruler resource blocks in the L+1th comb ruler resource block index; L is the integer obtained by rounding down N2, and the value of l is based on the relationship between the fractional part of N2 and M.

The subband indication information is used to indicate the multiple LBT subbands mapped to the corresponding resource pool, and the comb ruler resource block index indication information is used to indicate the comb ruler resource block index mapped to the corresponding resource pool in each LBT subband.

The configuration information for each resource pool indicates the number and location of the comb ruler resource block indexes configured in the corresponding resource pool. Therefore, this application provides a mapping method between resource pools and comb ruler resource block indexes to achieve resource pool resource configuration. This can meet the OCB requirements on the terminal-side unlicensed downlink frequency band, thereby satisfying potential diverse application scenarios and needs in the future.
