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] In the Internet of Vehicles (IoV), terminal devices communicate with each other via sidelinks (SL). A sidelink includes the Physical Sidelink Control Channel (PSCCH) and the Physical Sidelink Share Channel (PSSCH). The sidelink control information (SCI) in the PSCCH indicates the information needed to receive the PSSCH, such as PSSCH channel resources and transmission parameters. The PSSCH carries the data for sidelink communication. With the continuous emergence of various new services and applications, the performance requirements for sidelink communication between terminal devices will become increasingly stringent in terms of transmission bandwidth, communication speed range, communication latency, reliability, and scalability. Relying solely on the limited licensed frequency bands of operators cannot meet the potential diverse application scenarios and needs of the future. Therefore, it is necessary to research 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 a lack of effective methods for resource allocation of subchannels at the granularity of comb-scale resource blocks 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, vehicle-to-vehicle (V2V) communication, or intelligent driving, intelligent connected vehicles, and other fields. By designing the mapping method between sub-channels and IRB indexes, sub-channel configuration can be achieved, which 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.

[0006] In a first aspect, embodiments of this application provide a method for resource allocation, the method being executed by a network device, the method comprising:

[0007] Determine the size of the resource granularity;

[0008] Based on the size of the resource granularity and the mapping rules between the sub-channel and the comb ruler resource block index, determine the configuration information of at least one sub-channel;

[0009] The configuration information for each sub-channel indicates the number and location of the comb ruler resource block indexes configured for the corresponding sub-channel; the resource block value between two consecutive comb ruler resource blocks in the same comb ruler resource block index is M, and M is determined by the size of the subcarrier interval.

[0010] In this technical solution, the comb ruler resource block is divided into sub-channels to form sub-channel configuration information. This configuration information indicates the number and location of the comb ruler resource block indices configured for the corresponding sub-channel. Therefore, this application provides a mapping method between sub-channels and comb ruler resource block indices to achieve sub-channel configuration. This can meet the OCB requirements on the terminal-side downlink unlicensed frequency band, thereby satisfying potential diverse application scenarios and needs in the future.

[0011] In one implementation, determining the configuration information of at least one sub-channel based on the resource granularity and the mapping rule between the sub-channel and the comb ruler resource block index includes: determining the number of comb ruler resource block indices contained in each sub-channel based on the resource granularity; and determining the position of the comb ruler resource block index mapped to each sub-channel based on the mapping rule between the sub-channel and the comb ruler resource block index.

[0012] In one implementation, determining the size of the resource granularity includes: determining the size of the resource granularity based on the number of comb block indexes contained in a subchannel; or, determining the size of the resource granularity based on the number of subchannels contained in a Listen-Before-Speak LBT subband.

[0013] In one implementation, the mapping rule between the sub-channel and the comb ruler resource block index is as follows: starting from the first comb ruler resource block index in an LBT sub-band, one or more comb ruler resource blocks are mapped to a sub-channel according to the comb ruler resource block index number from smallest to largest.

[0014] In one possible implementation, the mapping rule between the sub-channel and the comb ruler resource block index is as follows: a sub-channel contains m1 comb ruler resource block indices, and the sub-channel is mapped to a continuous set of m1 comb ruler resource block indices; wherein, the number of comb ruler resource block indices contained in a LBT sub-band is m1 times the number of sub-channels contained therein, and m1 is a positive integer greater than 1 and less than or equal to M.

[0015] In one possible implementation, the mapping rule between the sub-channel and the comb ruler resource block index is as follows: a sub-channel contains m1 comb ruler resource block indices, and the sub-channel is mapped to the m1 non-contiguous comb ruler resource block indices; wherein, the number of comb ruler resource block indices contained in a LBT sub-band is m1 times the number of sub-channels contained therein, and m1 is a positive integer greater than 1 and less than M.

[0016] Optionally, mapping a sub-channel to the non-contiguous m1 comb ruler resource block indices includes: mapping the sub-channel to the m1 comb ruler resource block indices with odd-numbered indices; or, mapping the sub-channel to the m1 comb ruler resource block indices with even-numbered indices; or, mapping the sub-channel to the m1 comb ruler resource block indices, wherein the difference in index between adjacent comb ruler resource block indices among the m1 comb ruler resource block indices is x1, where x1 is the number of sub-channels included in the LBT subband, and x1 is an integer less than M.

[0017] In one possible implementation, the mapping rule between the sub-channel and the comb ruler resource block index is as follows: a sub-channel contains a+1 comb ruler resource block indices, and the sub-channel is mapped to all resource blocks in the a comb ruler resource block indices, either consecutively or non-consecutively, and to a portion of the comb ruler resource blocks in the remaining one of the a+1 comb ruler resource block indices; wherein, the number of comb ruler resource block indices contained in an LBT sub-band is m² times the number of sub-channels contained therein, where m² is a non-integer greater than 1 and less than M, and a is the value obtained by rounding down m².

[0018] In one possible implementation, the mapping rule between the sub-channel and the comb ruler resource block index is as follows: a sub-channel contains a+1 comb ruler resource block indices, and the sub-channel is mapped to all resource blocks in the a comb ruler resource block indices, either consecutively or non-consecutively, and the remaining one comb ruler resource block index in the a+1 indices is not mapped to the sub-channel; wherein, the number of comb ruler resource block indices contained in a LBT sub-band is m2 times the number of sub-channels contained therein, where m2 is a non-integer greater than 1 and less than M, and a is the value obtained by rounding down m2.

[0019] In one possible implementation, the mapping rule between the subchannel and the comb ruler resource block index is as follows: the remaining comb ruler resource blocks in one LBT subband that cannot form a complete subchannel are combined with the remaining comb ruler resource blocks in other LBT subbands to form a complete subchannel.

[0020] Optionally, the step of combining the remaining comb ruler resource blocks in one LBT subband that cannot form a complete subchannel with the remaining comb ruler resource blocks in other LBT subbands to form a complete subchannel includes: combining the remaining comb ruler resource blocks in one LBT subband that cannot form a complete subchannel with the comb ruler resource blocks in adjacent LBT subbands to form a complete subchannel; or, combining the remaining comb ruler resource blocks in multiple LBT subbands to form a complete subchannel, wherein each of the multiple LBT subbands contains at least one complete subchannel.

[0021] Secondly, embodiments of this application provide another method for resource allocation, the method being executed by a terminal device, the method comprising:

[0022] Receive sub-channel configuration information sent by network devices;

[0023] The configuration information of the sub-channel indicates the number and position of the comb ruler resource block indexes configured for the corresponding sub-channel; the resource block value between two consecutive comb ruler resource blocks in the same comb ruler resource block index is M, and M is determined by the size of the subcarrier interval.

[0024] In this technical solution, the sub-channel configuration is achieved by mapping the sub-channel to the comb ruler resource block index. This can meet the OCB requirements on the unlicensed frequency band of the terminal-side walkway, thereby satisfying potential diverse application scenarios and needs in the future.

[0070] 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.

[0071] Currently, with the continuous emergence of various new services and applications, the performance requirements of the sidelink (SL) in terms of transmission bandwidth, communication speed range, communication latency, reliability, and scalability are becoming increasingly higher. If we rely solely on the limited licensed spectrum of operators, we cannot meet the potential diverse application scenarios and needs in the future. Therefore, it is necessary to study sidelink-unlicensed (SL-U) technology that can be applied to unlicensed frequency bands.

[0072] In unlicensed frequency bands, the OCC (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). In related technologies, in SL-U systems, resource allocation is granular at the subchannel level, where each subchannel contains consecutive resource blocks (RBs). Subchannel configuration is achieved based on the mapping rules between subchannels and RBs. However, this configuration scheme typically incurs significant overhead to indicate the configured frequency domain resources in order to provide sufficiently flexible resource indication. Therefore, currently, there is a lack of effective methods for resource configuration at the subchannel level using resource blocks in SL-U systems.

[0073] 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 sub-channels and comb ruler resource block indices, the resource allocation of sub-channels can be realized. 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.

[0074] 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.

[0075] 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. Figure 1 The communication system shown is exemplified by a network device 101 and a terminal device 102.

[0076] 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.

[0077] 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.

[0078] 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 first and second terminal devices can also be referred to as terminal devices, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. Terminal devices can be communication-enabled vehicles, smart cars, mobile phones, wearable devices, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminal devices in industrial control, wireless terminal devices in self-driving, wireless terminal devices in remote medical surgery, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, wireless terminal devices in smart homes, and so on. The embodiments of this application do not limit the specific technology or device form used in the terminal devices.

[0079] 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.

[0080] The method and apparatus for resource allocation provided in this application will now be described in detail with reference to the accompanying drawings.

[0081] 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.

[0082] In step 201, the size of the resource granularity is determined.

[0083] In step 202, configuration information for at least one sub-channel is determined based on the resource granularity and the mapping rules between the sub-channel and the comb ruler resource block index.

[0084] In the embodiments of this application, the configuration information of each sub-channel indicates the number and position of the comb ruler resource block indexes configured for the corresponding sub-channel; the resource block value between two consecutive comb ruler resource blocks in the same comb ruler resource block index is M, and M is determined by the size of the subcarrier interval.

[0085] 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.

[0086] Table 4.4.4.6-1: Number of resource block interleavings

[0087] μ M 0 10 1 5

[0088] 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 4 As 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.

[0089] In embodiments of this application, when configuring sub-channels, network devices can map comb ruler resource blocks in the system to one or more sub-channels. That is, the comb ruler resource blocks in the system can be divided into one or more sub-channels to form a sub-channel configuration. This sub-channel configuration can include configuration information for each configured sub-channel. The configuration information for each configured sub-channel indicates the number and location of the comb ruler resource block indexes configured for the corresponding sub-channel, thereby realizing the sub-channel configuration. Optionally, each sub-channel can correspond to a unique sub-channel index number, which indicates the use of the comb ruler resource blocks contained in the corresponding sub-channel to carry control information and / or data information of the terminal device.

[0090] By implementing the embodiments of this application, one or more comb ruler resource block indices are divided into one or more sub-channels to form configuration information for each sub-channel. The configuration information for each sub-channel indicates the number and location of the comb ruler resource block indices configured for that sub-channel. Therefore, this application, by providing a mapping method between sub-channels and comb ruler resource block indices to achieve resource configuration for sub-channels, can solve the problem of high overhead in indicating configured frequency domain resources in the system, reduce the overhead of indicating configured frequency domain resources, and simultaneously meet OCB requirements on unlicensed downlink frequency bands on the terminal side, thereby satisfying potential diverse application scenarios and needs in the future.

[0091] In some embodiments of this application, the number of comb ruler resource block indices contained in each sub-channel can be determined according to the size of the resource granularity, and the position of the comb ruler resource block index mapped to each sub-channel can be determined according to the mapping rules between the sub-channel and the comb ruler resource block index.

[0092] Optionally, the size of the resource granularity can be understood as the granularity relationship between sub-channels and comb ruler resource block indexes. This application defines the granularity relationship between sub-channels and comb ruler resource block indexes. Based on this granularity relationship, the number of comb ruler resource block indexes contained in a sub-channel is determined. According to the mapping rules between sub-channels and comb ruler resource block indexes, the position of the comb ruler resource block indexes mapped to a sub-channel can be determined. In this way, based on the granularity relationship and mapping rules, the configuration information of the sub-channels configured by the network device can be determined.

[0093] In some embodiments of this application, the size of the resource granularity can be determined based on the number of comb block indexes contained in a subchannel; or, the size of the resource granularity can be determined based on the number of subchannels contained in a Listen-Before-Speak LBT subband.

[0094] In one implementation, the size of a subchannel, i.e., the resource granularity, can be determined by the number n of comb ruler resource block indices contained within it. Here, n can be understood as n comb ruler resource block indices contained in one subchannel. As an example, these n comb ruler resource block indices can be consecutive, or they can be non-consecutive. This number n can be predefined; or it can be preconfigured; or it can be determined in other ways, which will not be elaborated upon here.

[0095] In another implementation, the size of a subchannel, i.e., the resource granularity, can be determined by the number of subchannels contained in a subband. As an example, the number *m* of subchannels in a subband can be determined through predefinition or preconfiguration. Then, the number of comb ruler resource block indices contained in one subchannel is M / m, where M / m can be an integer or a non-integer. Here, M is the number of comb ruler resource block indices contained in a subband.

[0096] Optionally, the aforementioned number m can be a pre-configured set of values ​​by the network device (such as a base station), such as m = {1, 2, 5, 10}, and the specific value selected is indicated by the downlink signaling of the network device (such as the base station). For example, taking a subcarrier spacing (SCS) of 15 kHz and an LBT bandwidth of 20 MHz as an example, M = 10 represents the number of comb ruler resource block indices contained in one LBT subband. If one LBT subband contains two subchannels, then one subchannel contains five comb ruler resource block indices.

[0097] In other words, the number of comb ruler resource block indexes contained in each sub-channel can be determined based on the size of the resource granularity. Then, based on the mapping rules between sub-channels and comb ruler resource block indexes, the position of the comb ruler resource block indexes mapped to each sub-channel can be determined. This allows the configuration information of each sub-channel to be determined, which indicates the number and position of the comb ruler resource block indexes configured for the corresponding sub-channel.

[0098] It should be noted that, in the embodiments of this application, one subchannel can be mapped to one LBT subband, or one subchannel can be mapped to multiple LBT subbands. Different mapping methods correspond to different mapping rules. The following will describe the mapping rules between the subchannel and the comb ruler resource block index, taking into account the embodiments of mapping one subchannel to one LBT subband and mapping one subchannel to multiple LBT subbands.

[0099] For the case where one subchannel is mapped to one LBT subband:

[0100] In one implementation, the mapping rule between the subchannel and the comb ruler resource block index is as follows: starting from the first comb ruler resource block index in an LBT subband, one or more comb ruler resource blocks are mapped to a subchannel according to their comb ruler resource block index numbers in ascending order. That is, when one subchannel is mapped to one LBT subband, if the index number of the first comb ruler resource block in an LBT subband is 0, then starting from the comb ruler resource block index with index number 0 in that LBT subband, one or more comb ruler resource blocks are mapped to a subchannel according to their comb ruler resource block index numbers in ascending order.

[0101] In one possible implementation, the mapping rule between the subchannel and the comb ruler resource block index is as follows: a subchannel contains m1 comb ruler resource block indices, and a subchannel is mapped to m1 consecutive comb ruler resource block indices; wherein, the number of comb ruler resource block indices contained in an LBT subband is m1 times the number of subchannels contained therein, and m1 is a positive integer greater than 1 and less than or equal to M.

[0102] As an example, an LBT subband contains an integer x subchannels and an integer y comb ruler resource block indices, where y = m1 * x. Therefore, a subchannel can contain m1 comb ruler resource block indices, and a subchannel maps to a consecutive set of m1 comb ruler resource block indices. Optionally, when m1 = M, a subchannel can map to all M comb ruler resource block indices in an LBT subband, meaning a subchannel contains all M comb ruler resource block indices in an LBT subband.

[0103] For example, with a subcarrier spacing (SCS) of 15 kHz and an LBT bandwidth of 20 MHz, containing 5 sub-channels, and each LBT bandwidth containing 10 comb ruler resource block indices (e.g., IRB indices 0-9), and each sub-channel containing 20 resource blocks (RBs), then each sub-channel contains 2 comb ruler resource block indices. The sub-channel with index 0 (the first sub-channel among the 5 sub-channels) is mapped to consecutive IRB index 0 (comb ruler resource block index with index 0) and IRB index 1 (comb ruler resource block index with index 1). The sub-channel with index 1 (the second sub-channel among the 5 sub-channels) is mapped to consecutive IRB index 2 (comb ruler resource block index with index 2) and IRB index 3 (comb ruler resource block index with index 3). The sub-channel with index 2 (the third sub-channel among the 5 sub-channels) is mapped to consecutive IRB index 4 (comb ruler resource block index with index 4) and IRB index 2 (comb ruler resource block index with index 3). 5 (the comb block index with sequence number 5), the sub-channel with sequence number 3 (the fourth sub-channel among the 5 sub-channels) is mapped to the consecutive IRB index 6 (the comb block index with sequence number 6) and IRB index 7 (the comb block index with sequence number 7), and the sub-channel with sequence number 4 (the fifth sub-channel among the 5 sub-channels) is mapped to the consecutive IRB index 8 (the comb block index with sequence number 8) and IRB index 9 (the comb block index with sequence number 9).

[0104] In one possible implementation, the mapping rule between the subchannel and the comb ruler resource block index is as follows: a subchannel contains m1 comb ruler resource block indices, and a subchannel is mapped to m1 non-contiguous comb ruler resource block indices; wherein, the number of comb ruler resource block indices contained in an LBT subband is m1 times the number of subchannels contained therein, and m1 is a positive integer greater than 1 and less than M.

[0105] As an example, an LBT subband contains an integer x subchannels and an integer y comb ruler resource block indices, where y = m1 * x. Then, one subchannel contains m1 comb ruler resource block indices, and one subchannel is mapped to a non-contiguous set of m1 comb ruler resource block indices. For example, one subchannel can be mapped to m1 comb ruler resource block indices with odd-numbered indices; or, one subchannel can be mapped to m1 comb ruler resource block indices with even-numbered indices; or, one subchannel can be mapped to m1 comb ruler resource block indices, where the difference in index between adjacent comb ruler resource block indices is x1, where x1 is the number of subchannels contained in one LBT subband, and x1 is an integer less than M.

[0106] For example, with a subcarrier spacing (SCS) of 15 kHz and an LBT bandwidth of 20 MHz, this 20 MHz bandwidth contains 2 sub-channels, 1 LBT bandwidth contains 10 comb ruler resource block indices (such as IRB indexes 0-9), and 1 sub-channel contains 50 resource blocks (RBs). Thus, 1 sub-channel contains 5 comb ruler resource block indices. For example, sub-channel 0 is mapped to the even-numbered comb ruler resource block indices {0, 2, 4, 6, 8}, and sub-channel 1 is mapped to the odd-numbered comb ruler resource block indices {1, 3, 5, 7, 9}.

[0107] In one implementation, the mapping rule between the subchannel and the comb ruler resource block index is as follows: a subchannel contains a+1 comb ruler resource block indices, and a subchannel is mapped to all resource blocks in a consecutive or non-consecutive comb ruler resource block indices, as well as to a portion of the comb ruler resource blocks in the remaining one of the a+1 comb ruler resource block indices; wherein, the number of comb ruler resource block indices contained in an LBT subband is m2 times the number of subchannels contained therein, where m2 is a non-integer greater than 1 and less than M, and a is the value obtained by rounding down m2.

[0108] As an example, if a sub-band contains a number of comb ruler resource block indices that are m² times the number of sub-channels, where m² is a non-integer greater than 1 and less than M, the granularity of the sub-channel can be as follows: a sub-channel contains a+1 comb ruler resource block indices. The mapping relationship between the sub-channel and the comb ruler resource block indices can be that a sub-channel is mapped to all resource blocks in a consecutive or non-consecutive comb ruler resource block indices, and then further mapped to a portion of the comb ruler resource blocks in the remaining one comb ruler resource block index of the a+1 indices. For example, this portion of the comb ruler resource blocks could be the first 5 physical resource blocks in a comb ruler resource block index, or the last 5 physical resource blocks in a comb ruler resource block index, or all 5 physical resource blocks with odd numbers in a comb ruler resource block index, or all 5 physical resource blocks with even numbers in a comb ruler resource block index.

[0109] For example, such as Figure 5As shown, one LBT subband contains 5 comb ruler resource block indices (i.e., the comb ruler resource block index numbers are {0,1,2,3,4}), a total of 50 physical resource blocks (PRBs), and 2 sub-channels. Then, one sub-channel contains 3 comb ruler resource block indices. Sub-channel 0 (i.e., the first sub-channel of the 2 sub-channels) is mapped to the comb ruler resource block index with consecutive indexes {0,1}. Sub-channel 0 is also mapped to the 5 physical resource blocks with even indexes in the comb ruler resource block index with index number 2, i.e., physical resource blocks with indexes {2,12,22,32,42}. Subchannel 1 (i.e., the second of the two subchannels) is mapped to the five physical resource blocks with odd-numbered indices in the comb-scale resource block index with index number 2, namely the physical resource blocks PRB with indices {7, 17, 27, 37, 47}. Subchannel 1 is also mapped to all physical resource blocks in the comb-scale resource block index with indices {3, 4}.

[0110] For example, such as Figure 6 As shown, one LBT subband contains 5 comb ruler resource block indices (i.e., the sequence numbers of the comb ruler resource block indices are {0,1,2,3,4}), a total of 50 physical resource blocks (PRBs), and 2 sub-channels. Then, one sub-channel contains 3 comb ruler resource block indices. Sub-channel 0 (i.e., the first sub-channel of the 2 sub-channels) is mapped to the consecutive comb ruler resource block indices with sequence numbers {0,1}. Sub-channel 0 is also mapped to the first half of the 5 physical resource blocks in the comb ruler resource block index with sequence number 2, i.e., the physical resource blocks (PRBs) with sequence numbers {2,7,12,17,22}. Subchannel 1 (i.e., the second of the two subchannels) is mapped to the last half of the five physical resource blocks in the comb resource block index with sequence number 2, namely the physical resource blocks PRB with sequence numbers {27,32,37,42,47}. Subchannel 1 is also mapped to all physical resource blocks in the comb resource block index with sequence numbers {3,4}.

[0111] In one implementation, the mapping rule between the subchannel and the comb ruler resource block index is as follows: a subchannel contains a+1 comb ruler resource block indices, and a subchannel is mapped to all resource blocks in a consecutive or non-consecutive comb ruler resource block indices, and the remaining comb ruler resource block index in a+1 is not mapped to a subchannel; wherein, the number of comb ruler resource block indices contained in an LBT subband is m2 times the number of subchannels contained, where m2 is a non-integer greater than 1 and less than M, and a is the value obtained by rounding down m2.

[0112] As an example, if the comb ruler resource block indices in one LBT subband cannot form a complete subchannel, the remaining comb ruler resource block indices in that LBT subband can be left unmapped to that subchannel. That is, when the comb ruler resource block indices in one LBT subband cannot form a complete subchannel, no mapping relationship is established between the remaining comb ruler resource block indices and the subchannel. For example, assuming a subchannel length of 15 physical resource blocks and one LBT subband containing 100 physical resource blocks, then that LBT subband can contain 6 subchannels. These 6 subchannels are mapped to the comb ruler resource block indices numbered 0-8, and the remaining 10 physical resource blocks are not mapped to the comb ruler resource block index numbered 9. In other words, the remaining 10 physical resource blocks in the comb ruler resource block index numbered 9 are not mapped to the subchannel.

[0113] For the case where one subchannel is mapped to multiple LBT subbands:

[0114] In one implementation, the mapping rule between the subchannel and the comb ruler resource block index is as follows: the remaining comb ruler resource blocks in an LBT subband that cannot form a complete subchannel are combined with the remaining comb ruler resource blocks in other LBT subbands to form a complete subchannel.

[0115] In other words, if there are remaining comb ruler resource blocks in an LBT subband that cannot form a complete subchannel, these remaining comb ruler resource blocks can be combined with the remaining comb ruler resource blocks in other LBT subbands to form a complete subchannel, so as to support one subchannel being mapped to multiple LBT subbands.

[0116] In one possible implementation, such as Figure 7 As shown, the remaining comb ruler resource blocks in one LBT subband that cannot form a complete subchannel can form a complete subchannel with the comb ruler resource blocks in the adjacent LBT subband.

[0117] In one possible implementation, such as Figure 8 As shown, if there are remaining comb-scale resource blocks in each LBT subband that cannot form a complete subchannel, then the remaining comb-scale resource blocks in multiple LBT subbands are combined to form a complete subchannel. Each LBT subband must contain at least one complete subchannel. For example, taking a subchannel length of 75 physical resource blocks, a subcarrier spacing (SCS) of 15 kHz, and an LBT bandwidth of 20 MHz containing 100 physical resource blocks, then subband 0 contains a complete subchannel 0, subband 1 contains a complete subchannel 1, subband 2 contains a complete subchannel 2, and the remaining physical resource blocks in subband 0, subband 1, and subband 2 form a complete subchannel 3.

[0118] It should be noted that, in some embodiments of this application, the sub-channel configuration information, which maps comb resource blocks in the system to multiple sub-channels, needs to be communicated to the terminal devices of the system through a certain method. The sub-channel 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-layer signaling, such as radio resource control messages. The network device or a terminal device with the authority to send sub-channel configuration information can indicate the adopted sub-channel configuration through corresponding signaling.

[0119] By implementing the embodiments of this application, sub-channel configuration is performed using the predefined mapping rules between sub-channels and comb ruler resource block indices. This allows the determination of the number and location of comb ruler resource block indices contained in a sub-channel, enabling the sub-channel configuration to meet OCB requirements on the unlicensed SL-U band of the terminal-side walkway. This, in turn, can meet the potential diverse application scenarios and needs in the future.

[0120] 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 9 , Figure 9 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 9 As shown, the method for configuring this resource may include, but is not limited to, the following steps.

[0121] In step 901, the configuration information of the sub-channel sent by the network device is received.

[0122] In the embodiments of this application, the configuration information of the sub-channel indicates the number and position of the comb ruler resource block indexes configured for the corresponding sub-channel; the resource block value between two consecutive comb ruler resource blocks in the same comb ruler resource block index is M, and M is determined by the size of the subcarrier interval.

[0123] It should be noted that the subchannel configuration information, which maps the comb resource blocks in the system to multiple subchannels, needs to be communicated to the terminal devices of the system through a certain method. Optionally, based on the subchannel configuration, the network device can indicate the scheduled subchannel resources to the sending UE and / or receiving UE by indicating the subchannel index, for carrying the UE's control information and / or data information. The UE can also select one or more subchannels on the available subchannel resources for carrying and transmitting control information and / or data information.

[0124] Optionally, in embodiments of this application, when a terminal device accesses a network device, it can receive sub-channel configuration information sent by the network device. Based on this sub-channel configuration information and the mapping rules between the sub-channel and the comb ruler resource block index, the number and location of the comb ruler resource block indexes configured for the sub-channel scheduled by the terminal device can be determined at the sub-channel granularity. For a description of the mapping rules between the sub-channel and the comb ruler resource block index at the sub-channel granularity, please refer to the preceding description of the mapping rules and sub-channel granularity, which will not be repeated here.

[0125] By implementing the embodiments of this application, a mapping method between sub-channels and comb ruler resource block indexes is provided to realize the resource configuration of sub-channels. 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.
