[0037] It should be noted that traditional wireless communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, wireless communication systems can support not only traditional wireless communication systems, but also communication such as device-to-device (D2D), machine-to-machine (M2M), machine-type communication (MTC), vehicle-to-vehicle (V2V), vehicle-to-everything (V2X), and narrowband internet of things (NB-IoT).

Alternatively, the wireless communication system of this embodiment can also be applied to licensed spectrum. Licensed spectrum can also be considered as non-shared spectrum.

[0040] Since the embodiments of this application may be described in conjunction with terminals and network devices, the terminals and network devices involved will be described in detail below.

[0041] Specifically, a terminal can be user equipment (UE), a remote UE, a relay UE, an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a mobile device, a user terminal, a smart terminal, a wireless communication device, a user agent, or a user device. It should be noted that a relay device is a terminal capable of providing relay forwarding services to other terminals (including remote terminals). Additionally, a terminal can also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a next-generation communication system (such as an NR communication system), or a terminal in a future public land mobile network (PLMN), etc., without specific limitations.

[0042] Furthermore, the terminals can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; they can be deployed on water (such as ships); and they can also be deployed in the air (such as airplanes, balloons, and satellites).

[0043] Furthermore, the terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in autonomous driving, a wireless terminal device in remote medical care, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc.

[0044] Furthermore, the terminal may include a device with transceiver capabilities, such as a chip system. The chip system may include a chip, and may also include other discrete components.

[0045] Specifically, network equipment can be devices used for communication with terminals, responsible for radio resource management (RRM), quality of service (QoS) management, data compression and encryption, and data transmission and reception on the air interface side. Network equipment can be a base station (BS) in a communication system or a device deployed in a radio access network (RAN) to provide wireless communication functions. Examples include base stations (BTS) in GSM or CDMA communication systems, node Bs (NBs) in WCDMA communication systems, evolved node Bs (eNBs or eNodeBs) in LTE communication systems, next-generation evolved node Bs (ng-eNBs) in NR communication systems, next-generation node Bs (gNBs) in NR communication systems, master nodes (MNs) in dual-link architectures, and secondary nodes (SNs) in dual-link architectures, without specific limitations.

[0046] Furthermore, network devices can also be other devices in the core network (CN), such as access and mobility management function (AMF), user plan function (UPF), etc.; they can also be access points (APs) and relay stations in wireless local area networks (WLANs), communication devices in future PLMN networks, and communication devices in NTN networks, etc.

[0047] Furthermore, network devices may include means for providing wireless communication capabilities to terminals, such as a chip system. For example, a chip system may include a chip, and may also include other discrete components.

[0048] Furthermore, network devices can communicate with Internet Protocol (IP) networks, such as the Internet, private IP networks, or other data networks.

[0049] It should be noted that in some network deployments, a network device can be a standalone node to implement all the functions of the aforementioned base station. This can include centralized units (CUs) and distributed units (DUs), such as gNB-CU and gNB-DU; it can also include active antenna units (AAUs). The CU can implement some of the network device's functions, and so can the DU. For example, the CU is responsible for handling non-real-time protocols and services, implementing the functions of the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, and packet data convergence protocol (PDCP) layer. The DU is responsible for handling physical layer protocols and real-time services, implementing the functions of the radio link control (RLC) layer, medium access control (MAC) layer, and physical (PHY) layer. Additionally, the AAU can implement some physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this network deployment, higher-layer signaling (such as RRC layer signaling) can be considered to be sent by the DU, or jointly by the DU and AAU. It is understood that network devices can include at least one of CU, DU, and AAU. Furthermore, the CU can be classified as a network device in the radio access network (RAN), or it can be classified as a network device in the core network; no specific limitation is made in this regard.

[0050] Furthermore, the network equipment can possess mobility characteristics; for example, the network equipment can be a mobile device. Optionally, the network equipment can be a satellite or a balloon station. For example, the satellite can be a low Earth orbit (LEO) satellite, a medium Earth orbit (MEO) satellite, a geostationary earthorbit (GEO) satellite, or a high elliptical orbit (HEO) satellite. Optionally, the network equipment can also be a base station located on land, water, or other similar locations.

[0051] Furthermore, network devices can provide services to a cell, and terminals within that cell can communicate with the network devices through transmission resources (such as spectrum resources). This cell can include macro cells, small cells, metro cells, micro cells, pico cells, and femto cells, among others.

[0052] Based on the above description, the wireless communication system of this application embodiment will be described below as an example.

[0053] For an example, see the wireless communication system of this application embodiment. Figure 1 The wireless communication system 10 may include a terminal 110 and a network device 120, wherein the network device 120 may be a device that communicates with the terminal 110. Simultaneously, the network device 120 may provide communication coverage for a specific geographical area and may communicate with the terminal 110 located within that coverage area.

[0054] Optionally, the wireless communication system 10 may also include multiple network devices, and each network device may include a certain number of terminals within its coverage area, without specific limitations.

[0055] Optionally, the wireless communication system 10 may also include other network entities such as a network controller and a mobility management entity, without specific limitations.

[0056] Optionally, the communication between the network device and the terminal in the wireless communication system 10 can be wireless or wired communication, without specific restrictions.

[0057] First, some of the technical solutions involved in the embodiments of this application will be described to facilitate understanding by those skilled in the art.

[0058] 1. Unlicensed spectrum

[0059] The 3GPP standards organization has studied how to deploy NR networks on unlicensed spectrum in order to achieve fair and efficient use of unlicensed spectrum and improve the data transmission rate of communication systems.

[0060] In LTE communication systems, a listen-before-talk (LBT) mechanism is used to enable the coexistence of licensed assisted access (LAA) from different operators and other communication systems in unlicensed spectrum. Specifically, the LBT mechanism involves a clear channel assessment (CCA) performed on a terminal in unlicensed spectrum before it needs to transmit data. This CCA determines whether the current channel (in 20MHz units) is available. For example, an energy detection threshold can be used to determine if the channel is occupied. If the energy of the signal received by the terminal exceeds this threshold, the channel is considered occupied.

[0061] In the frequency domain resource allocation of unlicensed NR spectrum, the frequency domain resource allocation unit used for channel transmission (such as PUSCH transmission, PUCCH transmission, etc.) is an interlace, which can contain multiple uniformly distributed RBs. For example, for a bandwidth of 20MHz, the interlace can contain 10 or 11 uniformly distributed RBs.

[0062] For example, taking an interlace of 0 to 9 that contains 11 evenly distributed RBs as an example, such as Figure 2 As shown, interlace 0 consists of 11 RBs with RB indices of 0, 10, 20, ..., 90, 100, and interlace 1 consists of 11 RBs with RB indices of 1, 11, 21, ..., 91, 101, and so on.

[0063] 2. NR sidechain communication

[0064] In 2018, the 80th plenary session of the 3rd Generation Partnership Project (3GPP) approved the research project on 5G New Radio (NR) Vehicle to Everything (V2X), also known as NR sidechain communication.

[0065] V2X technology uses wireless communication, sensing, and other technologies to collect road traffic environment information. Through real-time, efficient, and bidirectional information exchange and sharing between vehicles, pedestrians, and infrastructure, it provides reliable traffic information to drivers and pedestrians, thereby effectively improving road system safety and the traffic environment. V2X technology can include vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P), vehicle-to-network (V2N), and vehicle-to-infrastructure (V2I) technologies.

[0066] The sidelink channel mainly consists of the physical sidelink control channel (PSCCH), the physical sidelink shared channel (PSSCH), the physical sidelink broadcast channel (PSBCH), and the physical sidelink feedback channel (PSFCH). The PSCCH can carry sidelink control information (SCI), which includes modulation and coding, time-domain and frequency-domain information, group identifiers, etc. The resources used to transmit the PSCCH can be located in a finite number of RBs within the starting sub-channel of the multiple sub-channels used to transmit the PSSCH, and the number of RBs is configured by higher-layer parameters.

[0067] In NR sidelink communication, the terminal can be configured by a higher layer to have one or more sidelink resource pools, which can be used to transmit PSSCH and can be composed of multiple RBs.

[0068] Furthermore, in the frequency domain resource allocation for NR sidelink communication, the unit of frequency domain resource used for sidelink transmission is a sub-channel, which can contain multiple continuously distributed and non-overlapping redundancies (RBs). The number of RBs contained in a sub-channel can be configured by the higher-layer parameter sl-SubchannelSize, while the starting RB contained in a sub-channel can be configured by the higher-layer parameter sl-StartRB-Subchannel.

[0069] For example, subchannel m (m = 0, 1, 2, ...) contains n subCHsize There are n RBs, and the encoding of each RB is n. RB =n subCHRBstart +m*n subCHsize +j(j=0,1,…,n subCHsize -1). Where, n subCHsize Configured by the higher-level parameter sl-SubchannelSize, n subCHRBstart Configured by the high-level parameter sl-StartRB-Subchannel.

[0070] It should be noted that the higher-level parameters sl-SubchannelSize and sl-StartRB-Subchannel can be carried by the higher-level parameter SL-ResourcePool, which specifies the configuration information of the resource pool for NR sidechain communication.

[0071] For example, the high-level parameter SL-ResourcePool can carry the following configuration information:

[0072]

[0073]

[0074] The following is a detailed description of a resource mapping configuration method according to an embodiment of this application, with reference to the accompanying drawings.

[0075] like Figure 3 The diagram shown is a flowchart illustrating a resource mapping configuration method according to an embodiment of this application, specifically including the following steps:

[0076] S310, network devices send configuration information.

[0077] Correspondingly, the terminal obtains this configuration information.

[0078] This configuration information can be used to determine the resource mapping relationship between M (M≥1) sub-channels and N (N≥1) interleaved sets, where M is an integer greater than or equal to 1 and N is an integer greater than or equal to 1.

[0079] It should be noted that, in the embodiments of this application, the sub-channel is a frequency domain resource allocation unit used for sidechain transmission, while the interlace is a frequency domain resource allocation unit used for channel transmission in unlicensed spectrum.

[0080] In addition, each of the M sub-channels can contain the same number of consecutive RBs, and each of the N interlaces can contain the same number of RBs.

[0081] S320. The terminal determines the resource mapping relationship between the M sub-channels and the N interleaved sets based on the configuration information.

[0082] It should be noted that, in the embodiments of this application, since the sub-channel is a frequency domain resource allocation unit used for side-chain transmission, and the interleaved set is a frequency domain resource allocation unit used for channel transmission in the unlicensed spectrum, in order to realize side-chain transmission in the unlicensed spectrum, the network device can send configuration information to the terminal, so that the terminal can determine the resource mapping relationship between M sub-channels and N interleaved sets according to the configuration information, thereby realizing the possibility of side-chain transmission in the unlicensed spectrum by configuring the resource mapping relationship between the sub-channels and the interleaved sets.

[0083] The following provides a detailed description of the M (M≥1) sub-channels and N (N≥1) interleaved sets in the embodiments of this application.

[0084] 1. The value of M

[0085] (1) Relationship between sidechain resource pool and sub-channel

[0086] In NR sidechain communication, network devices can configure one or more sidechain resource pools for the terminal through higher-level parameters (such as SL-BWP-PoolConfig, SL-BWP-PoolConfigCommon, etc.), or through pre-configuration. The sidechain resource pool can be used for sidechain transmission (such as PSSCH transmission), and can consist of multiple Resource Blocks (RBs).

[0087] In addition, in the frequency domain resource allocation of NR sidechain communication, network devices can also configure the number of continuously distributed and non-overlapping RBs contained in the sub-channel to the terminal through higher-layer parameters (such as sl-SubchannelSize), or through pre-configuration.

[0088] Therefore, the terminal can determine the number of sub-channels in the sidechain resource pool by the number of RBs contained in the sidechain resource pool and the number of consecutive RBs contained in the sub-channel, i.e., the value of M in the embodiments of this application.

[0089] In other words, the value of M can be determined by the number of RBs contained in the sidechain resource pool used for sidechain transmission and the number of consecutive RBs contained in the sub-channel.

[0090] 2. The value of N

[0091] (1) Relationship between sidechain resource pool and RB-sets

[0092] In NR communication, the bandwidth of a single carrier / BWP can vary considerably, potentially exceeding or falling below 20MHz. To support flexible carrier / BWP bandwidth allocation without restricting bandwidth allocation, either a bandwidth-limited bitwise Batch (LBT) approach or a narrowband approach can be used, as follows:

[0093] When the carrier / BWP is greater than 20MHz, the broadband LBT method is to perform LBT uniformly on the carrier / BWP;

[0094] When the carrier / BWP is greater than 20MHz, the narrowband approach is to divide the carrier / BWP into one or more resource block sets (RB-sets). That is, at least one RB-set is configured for the carrier / BWP. Each RB-set is a collection of multiple RBs, and each RB-set occupies a consecutive 20MHz or an integer multiple of 20MHz in the frequency domain.

[0095] In addition, in the embodiments of this application, configuring at least one RB-set to the carrier / BWP can be understood as the carrier / BWP associating or mapping at least one RB-sets, without any specific limitation.

[0096] For example, if the bandwidth of a carrier / BWP is 20MHz, then the carrier / BWP may be configured (or associated / mapped) with one RB-sets; if the bandwidth of a carrier / BWP is 40MHz, then the carrier / BWP may be configured (or associated / mapped) with two RB-sets, and so on.

[0097] Based on this, when the bandwidth range of the sidechain resource pool used for sidechain transmission is greater than or equal to 20MHz in the frequency domain, the embodiments of this application can configure L (L≥1) RB-sets to the sidechain resource pool through network configuration or pre-configuration, and each RB-sets contains multiple RBs, and the number of RBs contained in each RB-sets needs to be determined by the subcarrier spacing.

[0098] Similarly, configuring L RB-sets to a sidechain resource pool can be understood as the sidechain resource pool being associated with (or mapped to) L RB-sets.

[0099] For example, taking a sidechain resource pool with a bandwidth of 40MHz, a subcarrier spacing of 15kHz, and an RB occupying 12 consecutive subcarriers in the frequency domain as an example, since each RB-set occupies a consecutive 20MHz in the frequency domain, this sidechain resource pool may be configured (or associated / mapped) with 2 RB-sets. The indices (or numbers) of these 2 RB-sets in the sidechain resource pool are 0 and 1, respectively, and each RB-set may contain 100 RBs. The indices (or numbers) of these 100 RBs in the RB-sets can be from 0 to 99.

[0100] (2) Relationship between RB-sets and interlace

[0101] In the allocation of frequency domain resources in unlicensed NR spectrum, network devices can configure the number of uniformly distributed RBs included in the interlace to the terminal through higher-layer parameters, or through pre-configuration.

[0102] For example, for RB-sets occupying 20MHz, interlace 0 in the RB-sets can contain 11 RBs with RB indices (or numbers) of 0, 10, 20, ..., 90, 100.

[0103] Therefore, the terminal can determine the number of interlaces in the at least one RB-sets by the number of RBs contained in the at least one RB-sets configured to the sidechain resource pool and the number of RBs contained in the interlace, i.e., the value of N in the embodiments of this application.

[0104] The N interlaces can be in one RB-sets configured for the sidechain resource pool used for sidechain transmission, or in multiple RB-sets configured for the sidechain resource pool used for sidechain transmission.

[0105] It should be noted that for N interlaces in one RB-sets, it can be understood that one RB-sets configuration (or association / mapping) has N interlaces.

[0106] For N interlaces in multiple RB-sets, it can be understood that the multiple RB-sets configuration (or association / mapping) has N interlaces.

[0107] In other words, in the embodiments of this application, the total number of interlaces configured (or associated / mapped) by one RB-sets can be N, or the total number of interlaces configured (or associated / mapped) by multiple RB-sets can be N, and there is no specific limitation on this.

[0108] In summary, the value of N can be determined by the number of RBs contained in at least one RB-sets configured for the sidechain resource pool used for sidechain transmission and the number of RBs contained in the interlace.

[0109] For example, with a subcarrier spacing of 15 kHz, an RB-set may contain 100 consecutively distributed RBs, and an interlace may contain 10 evenly distributed RBs. Therefore, the RB-set may be configured (or associated / mapped) with 10 interlaces. The indices (or numbers) of these 10 interlaces in the RB-set can be 0 to 9, i.e., interlace 0, interlace 1, ..., interlace 9.

[0110] Since N interlaces can be in one RB-set (i.e., case one) or multiple RB-sets (i.e., case two), the resource mapping relationship between M sub-channels and N interlaced sets will be specifically described in the following embodiments of this application.

[0111] Scenario 1:

[0112] For N interlaces configured in one RB-sets for a sidechain resource pool used for sidechain transfer, the embodiments of this application can achieve the following resource mapping relationship through configuration information:

[0113] M sub-channels are mapped according to the index (or number) of N interlaces in a single RB-set.

[0114] It should be noted that the sidechain resource pool used for sidechain transmission may be configured (associated or mapped) with L (L≥1) RB-sets, and each of these L RB-sets may be configured (associated or mapped) with N interlaces.

[0115] Each of the L RB-sets has an index (or number) from low to high, such as RB-sets0, RB-sets 1, ..., RB-sets L-1, etc.

[0116] Similarly, each of the N interlaces has an index (or number) in the same RB-sets from low to high, such as interlace 0, interlace 1, ..., interlace N-1.

[0117] Similarly, each of the M sub-channels has an index (or number) from low to high, such as sub-channel 0, sub-channel 1, ..., sub-channel M-1.

[0118] Therefore, in "Scenario 1", each of the M sub-channels is mapped to the RBs contained in the N interlaces in the same RB-sets, meaning that the RBs contained in the interlaces mapped by the M sub-channels do not cross RB-sets.

[0119] In addition, through the configuration information, each of the M sub-channels is mapped sequentially according to the index (or number) order of the N interlaces in the same RB-sets.

[0120] In this context, sequential mapping can be understood as follows: the sub-channel with the lowest index (or number) is mapped starting from the interlace of the lowest index (or number); the sub-channel with the second lowest index (or number) is mapped starting from the interlace of the unmapped lowest index (or number); and so on.

[0121] For example, taking sub-channels with indices (or numbers) of 0 and 1 and interlaces with indices (or numbers) of 0 to 10 in a certain RB-sets as examples, sub-channel 0 is first mapped sequentially starting from interlace 0, and after sub-channel 0 is mapped, sub-channel 1 is then mapped sequentially starting from the lowest unmapped interlace with the lowest index (or number).

[0122] To map M sub-channels according to the index (or number) order of N interlaces in a single RB-set, the following methods can be used:

[0123] 1) M sub-channels are mapped sequentially to K continuously distributed interleaved sets according to the index order of N interlaces in a single RB-sets, where the value of K is less than or equal to the value of N (i.e., "Method 1");

[0124] 2) M sub-channels are mapped sequentially to K uniformly distributed interleaved sets according to the index order of N interlaces in a single RB-sets, where the value of K is less than or equal to the value of N (i.e., “Method 2”).

[0125] 3) M sub-channels are mapped sequentially to K interleaved sets of random or arbitrary distribution according to the index order of N interlaces in a single RB-set, where the value of K is less than or equal to the value of N (i.e., “Method 3”).

[0126] Method 1:

[0127] It should be noted that in "Method 1", if the sidechain resource pool is configured (or associated / mapped) with L (L≥1) RB-sets, and each of these L RB-sets is configured (or associated / mapped) with N (N≥1) interlaces, and the indices (or numbers) of these N interlaces are 0 to N-1 respectively, then

[0128] When the indices (or numbers) of the M (M≥1) sub-channels are 0 to M-1 respectively, the interlace mapped to sub-channel i (i=0,1,…,M-1) satisfies the following relationship:

[0129] sub-channel 0={interlace 0,interlace 1,…,interlace K-1};

[0130] sub-channel i={interlace i*K, interlace i*K+1,…, interlace i*K+K-1}, K≤N;

[0131] sub-channel M-1={interlace(M-1)*K, interlace(M-1)*K+1,…,interlace N-1}.

[0132] The value of K can be configured by the configuration information issued by the network device; or, the value of K can satisfy the following relationship: K = N / M.

[0133] For example, taking a sidechain resource pool with a bandwidth of 40MHz, a subcarrier spacing of 15kHz, and an RB occupying 12 consecutive subcarriers in the frequency domain, the sidechain resource pool is configured (or associated / mapped) with 2 (i.e., L=2) RB-sets. The indices (or numbers) of these two RB-sets in the sidechain resource pool are 0 and 1, respectively, and each RB-set contains 100 RBs. The indices (or numbers) of these 100 RBs in the RB-set can be from 0 to 99.

[0134] When an interlace contains 10 evenly distributed RBs, the RB-sets are configured (or associated / mapped) with 10 (i.e., N=10) interlaces. The indices (or numbers) of these 10 interlaces in the RB-sets are 0 to 9, namely interlace 0, interlace 1, ..., interlace 9. The indices (or numbers) of the RBs contained in interlace 0 are 0, 10, 20, ..., 90, the indices (or numbers) of the RBs contained in interlace 1 are 1, 11, 21, ..., 91, the indices (or numbers) of the RBs contained in interlace 2 are 2, 12, 22, ..., 92, and so on.

[0135] When the indices (or numbers) of the 2 (i.e., M=2) sub-channels are 0 to 2 respectively, K=N / M=5, and the following resource mapping relationship is satisfied:

[0136] Sub-channel 0 is mapped to the RBs contained in interlaces 0 to 4, i.e., sub-channel 0 = {interlace 0, interlace 1, interlace 2, interlace 3, interlace 4};

[0137] Sub-channel 1 is mapped to the RBs contained in interlaces 5 to 9, i.e., sub-channel 1 = {interlace 5, interlace 6, interlace 7, interlace 8, interlace 9}.

[0138] Method 2:

[0139] It should be noted that in "Method Two", if the sidechain resource pool is configured (or associated / mapped) with L (L≥1) RB-sets, and each of these L RB-sets is configured (or associated / mapped) with N (N≥1) interlaces, and the indices (or numbers) of these N interlaces are 0 to N-1 respectively, then

[0140] When the indices (or numbers) of the M (M≥1) sub-channels are 0 to M-1 respectively, the interlace mapped to sub-channel i (i=0,1,…,M-1) satisfies the following relationship:

[0141] sub-channel 0={interlace 0,interlace floor(N / K),…,interlace(K-1)*floor(N / K)};

[0142] sub-channel i={interlace i,interlace i+floor(N / K),…,interlace i+(K-1)*floor(N / K)}, K≤N;

[0143] sub-channel M-1={interlace M-1, interlace(M-1)+floor(N / K),…,interlace N-1}.

[0144] The value of K can be configured by the configuration information issued by the network device; or, the value of K can satisfy the following relationship: K = N / M.

[0145] For example, taking a sidechain resource pool with a bandwidth of 40MHz, a subcarrier spacing of 15kHz, and an RB occupying 12 consecutive subcarriers in the frequency domain, the sidechain resource pool is configured (or associated / mapped) with 2 (i.e., L=2) RB-sets. The indices (or numbers) of these two RB-sets in the sidechain resource pool are 0 and 1, respectively, and each RB-set contains 100 RBs. The indices (or numbers) of these 100 RBs in the RB-set can be from 0 to 99.

[0146] When an interlace contains 10 evenly distributed RBs, the RB-sets configuration (or association / mapping) has 10 (i.e., N=10) interlaces. The indices (or numbers) of these 10 interlaces in the RB-sets can be 0 to 9, i.e., interlace 0, interlace 1, ..., interlace 9. The indices (or numbers) of the RBs contained in interlace 0 are 0, 10, 20, ..., 90, the indices (or numbers) of the RBs contained in interlace 1 are 1, 11, 21, ..., 91, the indices (or numbers) of the RBs contained in interlace 2 are 2, 12, 22, ..., 92, and so on.

[0147] When the indices (or numbers) of the 2 (i.e., M=2) sub-channels are 0 to 2 respectively, K=N / M=5, and the following resource mapping relationship is satisfied:

[0148] Sub-channel 0 is mapped to the RBs contained in interlace 0, interlace 2, interlace 4, interlace 6, and interlace 8, i.e., sub-channel 0 = {interlace 0, interlace 2, interlace 4, interlace 6, interlace 8}.

[0149] Sub-channel 1 is mapped to the RBs contained in interlace 1, interlace 3, interlace 5, interlace 7, and interlace 9, i.e., sub-channel 1 = {interlace 1, interlace 3, interlace 5, interlace 7, interlace 9}.

[0150] Method 3:

[0151] It should be noted that in "Method 3", if the sidechain resource pool is configured (or associated / mapped) with L (L≥1) RB-sets, and each of these L RB-sets is configured (or associated / mapped) with N (N≥1) interlaces, and the indices (or numbers) of these N interlaces are 0 to N-1 respectively, then

[0152] When the indices (or numbers) of the M (M≥1) sub-channels are 0 to M-1 respectively, the interlace mapped to sub-channel i (i=0,1,…,M-1) is a random distribution or K interlaces with arbitrary distribution.

[0153] For example, taking a sidechain resource pool with a bandwidth of 40MHz, a subcarrier spacing of 15kHz, and an RB occupying 12 consecutive subcarriers in the frequency domain, the sidechain resource pool is configured (or associated / mapped) with 2 (i.e., L=2) RB-sets. The indices (or numbers) of these two RB-sets in the sidechain resource pool are 0 and 1, respectively, and each RB-set contains 100 RBs. The indices (or numbers) of these 100 RBs in the RB-set can be from 0 to 99.

[0154] When an interlace contains 10 evenly distributed RBs, the RB-sets configuration (or association / mapping) has 10 (i.e., N=10) interlaces. The indices (or numbers) of these 10 interlaces in the RB-sets can be 0 to 9, i.e., interlace 0, interlace 1, ..., interlace 9. The indices (or numbers) of the RBs contained in interlace 0 are 0, 10, 20, ..., 90, the indices (or numbers) of the RBs contained in interlace 1 are 1, 11, 21, ..., 91, the indices (or numbers) of the RBs contained in interlace 2 are 2, 12, 22, ..., 92, and so on.

[0155] When the indices (or numbers) of the 2 (i.e., M=2) sub-channels are 0 to 2 respectively, K=5, and the following resource mapping relationship is satisfied:

[0156] Sub-channel 0 is mapped to the RBs contained in interlace 0, interlace 1, interlace 5, interlace 6, and interlace 8, i.e., sub-channel 0 = {interlace 0, interlace 1, interlace 5, interlace 6, interlace 8}.

[0157] Sub-channel 1 is mapped to the RBs contained in interlace 2, interlace 3, interlace 4, interlace 7, and interlace 9, i.e., sub-channel 1 = {interlace 2, interlace 3, interlace 4, interlace 7, interlace 9}.

[0158] Scenario 2:

[0159] For N interlaces configured in multiple RB-sets for the sidechain resource pool used for sidechain transfer, the embodiments of this application can achieve the following resource mapping relationship through configuration information:

[0160] M sub-channels are mapped according to the index order of the multiple RB-sets in the sidechain resource pool and the index order of the N interlaces in the multiple RB-sets.

[0161] It should be noted that, unlike "Scenario 1" above, the sidechain resource pool used for sidechain transmission may be configured (or associated / mapped) with L (L≥1) RB-sets, and these L RB-sets may be configured (associated or mapped) with a total of N interlaces. The number of interlaces configured (associated or mapped) in each RB-set can be the same or different; there is no specific restriction on this.

[0162] Therefore, in "Scenario 2", each of the M sub-channels is mapped to the RBs contained in the N interlaces of the L RB-sets, that is, the RBs of the interlaces mapped by the M sub-channels can cross RB-sets.

[0163] In addition, through the configuration information, each of the M sub-channels is mapped sequentially according to the index (or number) order of the N interlaces in their respective configured (or associated / mapped) RB-sets.

[0164] In this context, sequential mapping can be understood as follows: the sub-channel with the lowest index (or number) starts mapping from the lowest index (or number) interlace in the RB-sets of the lowest index (or number); the sub-channel with the second lowest index (or number) starts mapping from the unmapped lowest index (or number) interlace in the RB-sets of the lowest index (or number), and so on.

[0165] For example, taking sub-channels with indices (or numbers) 0 and 1, RB-sets with indices (or numbers) 0 to 1, and interlaces with indices (or numbers) 0 to 4 in each RB-set as an example, sub-channel 0 first starts mapping sequentially from interlace 0 in RB-sets 0, and after sub-channel 0 is mapped, sub-channel 1 starts mapping sequentially from the unmapped interlace in the lowest index (or number) of the RB-sets.

[0166] To map M sub-channels according to the index order of the multiple RB-sets in the sidechain resource pool and the index order of N interlaces in the multiple RB-sets, the following methods can be used:

[0167] 1) M sub-channels are mapped sequentially to T consecutively distributed interlaces according to the index order of the multiple RB-sets in the sidechain resource pool and the index order of N interlaces in the multiple RB-sets, where the value of T is less than the value of N (i.e., method 1).

[0168] 2) M sub-channels are mapped sequentially to T uniformly distributed interlaces according to the index order of the multiple RB-sets in the sidechain resource pool and the index order of N interlaces in the multiple RB-sets, where the value of T is less than the value of N (i.e., method 2).

[0169] 3) M sub-channels are mapped sequentially to T interlaces of random or arbitrary distribution according to the index order of the multiple RB-sets in the sidechain resource pool and the index order of N interlaces in the multiple RB-sets, where the value of T is less than the value of N (i.e., method 3).

[0170] Method 1:

[0171] It should be noted that in "Method 1", if the sidechain resource pool is configured (or associated / mapped) with L (L≥1) RB-sets, and the indices (or numbers) of these L RB-sets are 0 to L-1 respectively, and these L RB-sets are configured (or associated / mapped) with a total of N (N≥1) interlaces, and the number of interlaces configured (or associated / mapped) in each RB-set is the same, that is, each RB-set is configured (or associated / mapped) with N / L interlaces, and the indices (or numbers) of these N interlaces are 0 to N-1 respectively, then

[0172] When the indices (or numbers) of the M (M≥1) sub-channels are 0 to M-1 respectively, the interlace mapped to sub-channel i (i=0,1,…,M-1) satisfies the following relationship:

[0173] 1) If 2*N / L>T>N / L, then

[0174] sub-channel 0 = {interlace 0 in RB-sets 0, ..., interlac TN / L-1 in RB-sets 1};

[0175] sub-channel 1 = {interlace TN / L in RB-sets 1, ...};

[0176] …;

[0177] sub-channel M-1 = {…, interlace N / L-1 in RB-sets L-1};

[0178] 2) If T≤N / L, then

[0179] sub-channel 0 = {interlace 0 in RB-sets 0, ..., interlace T-1 in RB-sets 0};

[0180] sub-channel 1 = {interlace T, ...} in RB-sets 0;

[0181] …;

[0182] sub-channel M-1 = {…, interlace N / L-1 in RB-sets L-1};

[0183] The value of T can be configured by the configuration information issued by the network device; or, the value of T can satisfy the following relationship: T = N / M.

[0184] For example, taking a sidechain resource pool with a bandwidth of 40MHz, a subcarrier spacing of 15kHz, and an RB occupying 12 consecutive subcarriers in the frequency domain, the sidechain resource pool is configured (or associated / mapped) with 2 (i.e., L=2) RB-sets. The indices (or numbers) of these two RB-sets in the sidechain resource pool are 0 and 1, respectively, and each RB-set contains 100 RBs. The indices (or numbers) of these 100 RBs in the RB-set can be from 0 to 99.

[0185] When an interlace contains 10 evenly distributed RBs, the two RB-sets configuration (or association / mapping) have 20 (i.e., N=20) interlaces. The indices (or numbers) of these 20 interlaces in the two RB-sets are 0 to 9, namely interlace 0 in RB-sets 0, interlace 1 in RB-sets 0, ..., interlace 9 in RB-sets 0, and interlace 0 in RB-sets 1, ..., interlace 9 in RB-sets 1. Furthermore, the indices (or numbers) of the RBs contained in interlace 0 of RB-sets 0 are 0, 10, 20, ..., 90; the indices (or numbers) of the RBs contained in interlace 1 of RB-sets 0 are 1, 11, 21, ..., 91; the indices (or numbers) of the RBs contained in interlace 0 of RB-sets 1 are 0, 10, 20, ..., 90, and so on.

[0186] When the indices (or numbers) of the 5 (i.e., M=5) sub-channels are 0 to 2 respectively, T=N / M=4, and the following resource mapping relationship is satisfied:

[0187] Sub-channel 0 is mapped to the RBs contained in interlaces 0 to 3 in RB-sets 0, that is, sub-channel 0 = {interlace 0 in RB-sets 0, interlace 1 in RB-sets 0, interlace 2 in RB-sets 0, interlace 3 in RB-sets 0};

[0188] Sub-channel 1 is mapped to the RBs contained in interlaces 4 to 7 in RB-sets 0, that is, sub-channel 1 = {interlace 4 in RB-sets 0, interlace 5 in RB-sets 0, interlace 6 in RB-sets 0, interlace 7 in RB-sets 0};

[0189] Sub-channel 2 is mapped to the RBs contained in interlaces 8-9 in RB-sets 0 and the RBs contained in interlaces 0-1 in RB-sets 1, that is, sub-channel 2 = {interlace 8 in RB-sets 0, interlace 9 in RB-sets 0, interlace 0 in RB-sets 1, interlace 1 in RB-sets 1};

[0190] Sub-channel 3 is mapped to the RBs contained in interlaces 2 to 5 in RB-sets 1, that is, sub-channel 3 = {interlace 2 in RB-sets 1, interlace 3 in RB-sets 1, interlace 4 in RB-sets 1, interlace 5 in RB-sets 1};

[0191] Sub-channel 4 is mapped to the RBs contained in interlaces 6 to 9 in RB-sets 1, that is, sub-channel 4 = {interlace 6 in RB-sets 1, interlace 7 in RB-sets 1, interlace 8 in RB-sets 1, interlace 9 in RB-sets 1}.

[0192] Method 2:

[0193] It should be noted that in "Method 2", if the sidechain resource pool is configured (or associated / mapped) with L (L≥1) RB-sets, and the indices (or numbers) of these L RB-sets are 0 to L-1 respectively, and these L RB-sets are configured (or associated / mapped) with a total of N (N≥1) interlaces, and each RB-set has the same number of interlaces configured (or associated / mapped), that is, each RB-set has N / L interlaces configured (or associated / mapped), and the indices (or numbers) of these N interlaces are 0 to N-1 respectively, then

[0194] When the indices (or numbers) of the M (M≥1) sub-channels are 0 to M-1 respectively, the interlace mapped to sub-channel i (i=0,1,…,M-1) satisfies the following relationship:

[0195] 1) If 2*L>T>L, then

[0196] sub-channel 0 = {interlace 0 in RB-sets 0, interlace floor(N / T) in RB-sets 0, interlace N / L-2*floor(N / T)-2 in RB-sets 1, ...};

[0197] sub-channel 1 = {interlace 1 in RB-sets 0, interlace floor(N / T)+1 in RB-sets 0, interlace N / L-2*floor(N / T)-1 in RB-sets 1, ...};

[0198] …;

[0199] sub-channel M-1 = {…, interlace N / L-1 in RB-sets L-1}.

[0200] The value of T can be configured by the configuration information issued by the network device; or, the value of T can satisfy the following relationship: T = N / M.

[0201] For example, taking a sidechain resource pool with a bandwidth of 40MHz, a subcarrier spacing of 15kHz, and an RB occupying 12 consecutive subcarriers in the frequency domain, the sidechain resource pool is configured (or associated / mapped) with 2 (i.e., L=2) RB-sets. The indices (or numbers) of these two RB-sets in the sidechain resource pool are 0 and 1, respectively, and each RB-set contains 100 RBs. The indices (or numbers) of these 100 RBs in the RB-set can be from 0 to 99.

[0202] When an interlace contains 10 evenly distributed RBs, the two RB-sets configuration (or association / mapping) have 20 (i.e., N=20) interlaces. The indices (or numbers) of these 20 interlaces in the two RB-sets are 0 to 9, namely interlace 0 in RB-sets 0, interlace 1 in RB-sets 0, ..., interlace 9 in RB-sets 0, and interlace 0 in RB-sets 1, ..., interlace 9 in RB-sets 1. Furthermore, the indices (or numbers) of the RBs contained in interlace 0 of RB-sets 0 are 0, 10, 20, ..., 90; the indices (or numbers) of the RBs contained in interlace 1 of RB-sets 0 are 1, 11, 21, ..., 91; the indices (or numbers) of the RBs contained in interlace 0 of RB-sets 1 are 0, 10, 20, ..., 90, and so on.

[0203] When the indices (or numbers) of the 5 (i.e., M=5) sub-channels are 0 to 2 respectively, T=N / M=4, and the following resource mapping relationship is satisfied:

[0204] Sub-channel 0 is mapped to the RBs contained in interlaces 0 and 5 in RB-sets 0 and the RBs contained in interlaces 0 and 5 in RB-sets 1, i.e., sub-channel 0 = {interlace 0 in RB-sets 0, interlace 5 in RB-sets 0, interlace 0 in RB-sets 1, interlace 5 in RB-sets 1};

[0205] Sub-channel 1 is mapped to the RBs contained in interlaces 1 and 6 in RB-sets 0 and the RBs contained in interlaces 1 and 6 in RB-sets 1, i.e., sub-channel 0 = {interlace 1 in RB-sets 0, interlace 6 in RB-sets 0, interlace 1 in RB-sets 1, interlace 6 in RB-sets 1};

[0206] Sub-channel 2 is mapped to the RBs contained in interlaces 2 and 7 in RB-sets 0 and the RBs contained in interlaces 2 and 7 in RB-sets 1, i.e., sub-channel 0 = {interlace 2 in RB-sets 0, interlace 7 in RB-sets 0, interlace 2 in RB-sets 1, interlace 7 in RB-sets 1};

[0207] Sub-channel 3 is mapped to the RBs contained in interlaces 3 and 8 in RB-sets 0 and the RBs contained in interlaces 3 and 8 in RB-sets 1, i.e., sub-channel 0 = {interlace 3 in RB-sets 0, interlace 8 in RB-sets 0, interlace 3 in RB-sets 1, interlace 8 in RB-sets 1};

[0208] Sub-channel 4 is mapped to the RBs contained in interlaces 4 and 9 in RB-sets 0 and the RBs contained in interlaces 4 and 9 in RB-sets 1, i.e., sub-channel 0 = {interlace 4 in RB-sets 0, interlace 9 in RB-sets 0, interlace 4 in RB-sets 1, interlace 9 in RB-sets 1}.

[0209] Method 3:

[0210] It should be noted that in "Method 3", if the sidechain resource pool is configured (or associated / mapped) with L (L≥1) RB-sets, and the indices (or numbers) of these L RB-sets are 0 to L-1 respectively, and these L RB-sets are configured (or associated / mapped) with a total of N (N≥1) interlaces, and the number of interlaces configured (or associated / mapped) in each RB-set is the same, that is, each RB-set is configured (or associated / mapped) with N / L interlaces, and the indices (or numbers) of these N interlaces are 0 to N-1 respectively, then

[0211] When the indices (or numbers) of the M (M≥1) sub-channels are 0 to M-1 respectively, the interlace mapped to sub-channel i (i=0,1,…,M-1) is a random distribution or an arbitrary distribution of T interlaces, which is similar to the above and will not be repeated here.

[0212] The above analysis mainly explored the resource mapping relationship between M sub-channels and N interlaces. The following section will provide a detailed explanation of the association (or mapping) relationship between the resources used for transmitting PSCCH and the N interlaces.

[0213] It should be noted that, in the embodiments of this application, the network device can configure the association (or mapping) relationship between the resources used for transmitting PSCCH and N interlaces through configuration information.

[0214] For example, after configuring the resource mapping relationship between M sub-channels and N interlaces through configuration information, the terminal then determines the association (or mapping) relationship between the resources used to transmit PSCCH and the N interlaces based on the configuration information and the resource mapping relationship.

[0215] 1. Resources used for transmitting PSCCH

[0216] It should be noted that the resources used to transmit PSSCH can be associated with at least one of the M sub-channels, so that PSSCH can be transmitted through the associated sub-channel, and this association can be configured by the network or pre-configured.

[0217] For example, a finite number of RBs within the lowest index (or highest index / any index) of the M sub-channels can be associated with resources for transmitting PSSCH via higher-layer signaling; or, a finite number of RBs within multiple sub-channels of the M sub-channels can be associated with resources for transmitting PSSCH via higher-layer signaling, without any specific restrictions.

[0218] Since the resources used for transmitting PSSCH are associated with the sub-channels of M sub-channels, and the sub-channels of M sub-channels are mapped to N interlaces, in order to associate (or map) the resources used for transmitting PSSCH with the N interlaces, this embodiment of the application needs to determine the association (or mapping) relationship between the resources used for transmitting PSSCH and the N interlaces based on the configuration information and the above-mentioned resource mapping relationship.

[0219] For the case where the resource used to transmit PSCCH is associated with the first sub-channel among M sub-channels (the first sub-channel can be one or more sub-channels), the embodiments of this application can achieve the following association (or mapping) relationship through configuration information and the above-mentioned resource mapping relationship:

[0220] The resources used to transmit PSCCH are associated according to the index order of the RBs in the interlace mapped by the first sub-channel.

[0221] It should be noted that the interlace mapped to the first sub-channel can be determined through the descriptions in "Scenario 1" or "Scenario 2" above, and will not be repeated here.

[0222] For example, in "Situation 1" "Method 1", if the first sub-channel is sub-channel 0, then the interlace mapped by the first sub-channel is interlace 0, interlace 1, interlace 2, interlace 3, and interlace 4.

[0223] The resources used for transmitting PSCCH can be associated according to the index order of the RBs in the interlace mapped by the first sub-channel, as follows:

[0224] 1) The resources used to transmit PSCCH are associated in the order of the index of all RBs contained in all interlaces mapped by the first sub-channel (i.e., “method a”);

[0225] 2) The resources used to transmit PSCCH are associated in the order of the indexes of all RBs contained in the lowest index of the interlace mapped by the first sub-channel (i.e., “method b”);

[0226] 3) Resources used for transmitting PSCCH are associated in an index order starting with the lowest index of the RB contained in the interlace mapped by the lowest index of the first sub-channel (i.e., “method c”).

[0227] Method a:

[0228] It should be noted that in "Method a", the RB associated with the resource used to transmit PSCCH may have interlace issues.

[0229] Specifically, the resources used for transmitting PSCCH and the N interlaces can satisfy the following association (or mapping) relationship:

[0230] 1) The resources used to transmit PSCCH are associated with the lowest index of P RBs among all RBs contained in all interlaces mapped by the first sub-channel, and the value of P is determined by the configuration information.

[0231] 2) The resources used to transmit PSCCH are associated with the P RBs with the highest index among all RBs contained in all interlaces mapped by the first sub-channel, and the value of P is determined by the configuration information.

[0232] 3) The resources used to transmit PSCCH are associated with any P RBs among all RBs contained in all interlaces mapped by the first sub-channel, and the value of P is determined by the configuration information.

[0233] For example, if the first sub-channel is sub-channel 0, sub-channel 0 = {interlace0, interlace 1}, the indices (or numbers) of the RBs contained in interlace 0 are 0, 10, 20, ..., 90, and the indices (or numbers) of the RBs contained in interlace 1 are 1, 11, 21, ..., 91, and the configuration information is configured as P = 5, then...

[0246] When the resources used to transmit PSCCH are associated with Q (Q=5) RBs of the lowest index among all RBs contained in the lowest index interlace mapped by the first sub-channel, the resources used to transmit PSCCH are associated with (or mapped) to RB0, RB10, RB20, RB30, and RB40, that is, the 5 RBs RB0, RB10, RB20, RB30, and RB40 are used to transmit PSCCH;

[0247] When the resources used to transmit PSCCH are associated with the Q RBs of the highest index among all RBs contained in the lowest index interlace mapped by the first sub-channel, the resources used to transmit PSCCH are associated with (or mapped) to RB 50, RB60, RB 70, RB 80, and RB 90.

[0248] When the resources used to transmit PSCCH are associated with the Q RBs of the lowest index among all RBs contained in the highest index interlace mapped by the first sub-channel, the resources used to transmit PSCCH are associated with (or mapped) to RB 1, RB11, RB 21, RB 31, RB 41.

[0256] 4) The resources used to transmit PSCCH are associated with S RBs starting from any index of any interlace mapped by the first sub-channel, and the value of S is determined by the configuration information.

[0257] For example, if the first sub-channel is sub-channel 0, sub-channel 0 = {interlace0, interlace 1}, the indices (or numbers) of the RBs contained in interlace 0 are 0, 10, 20, ..., 90, and the indices (or numbers) of the RBs contained in interlace 1 are 1, 11, 21, ..., 91, and the configuration information is configured as S = 11, then...

[0258] When the resources used to transmit PSCCH are associated with S (S=11) RBs starting with the lowest index of the RB contained in the interlace mapped by the first sub-channel, the resources used to transmit PSCCH are associated with (or mapped) to RB 0, RB 10, RB 20, RB 30, RB 40, RB 50, RB 60, RB 70, RB 80, RB 90, RB 1;

[0259] When the resources used for transmitting PSCCH are associated with S RBs starting with an RB of any index contained in the interlace of the lowest index mapped by the first sub-channel, and the RB of that arbitrary index is RB 20, the resources used for transmitting PSCCH are associated with (or mapped to) RB 20, RB 30, RB 40, RB 50, RB 60, RB 70, RB 80, RB 90, RB1, RB 21, and RB 31.
