[0002] With the proposal of the 5th Generation Mobile Communication Technology (5G), 5G communication technologies have become increasingly mature, and the versions of 5G communication technologies are constantly updated and iterated. To support services with higher data rates (Gbps), such as Augmented Reality (AR) / Virtual Reality (VR), real-time video sharing, etc., the new version technology of 5G communication proposes an R18 sidelink technology standard for extended commercial use cases. In the process of implementing the R18 sidelink technology, a beam-based directional transceiver resource is proposed. That is, when a beam-based directional transmission resource is adopted, the degrees of freedom in space are provided, making it possible for user equipment (UE) with different beam directions to use the same time-frequency domain resources for transmission.

[0003] However, when the R18 sidelink unicast service supports beam-based directional transceiver, it will bring more restrictions to the resource allocation of the base station, such as restrictions in the time domain and / or frequency domain resources, to ensure that there are no resource conflicts in the time domain resources or frequency domain resources when the transmitting user equipment (UE) communicates with the receiving UE that can communicate with it.

[0058] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application.

[0059] An embodiment of the present application provides a reporting method. The method is applied to a terminal, and the method includes step 101 or step 102:

[0060] Step 101: Report first information.

[0061] The first information is used to provide direct link transmission information to a node, and the first information includes at least one of the following:

[0062] At least one first reference signal resource index;

[0063] A first resource or a resource set.

[0064] In the embodiments of the present application, the terminal is a terminal network communication device, such as a smart mobile phone, or other intelligent vehicles that can perform Internet communication. The first information is determined according to the initial beam matching result after the initial beam matching between the terminal and at least one other terminal, and is used to request beam-based unicast service resource information. The first reference signal resource index is used to indicate the beam direction to the node, and the first resource or resource set is the time-domain and frequency-domain resources available to the terminal.

[0065] Step 102: Report second information.

[0066] The second information is used to provide an authorization index for physical direct link control channel / physical direct link shared channel PSCCH / PSSCH transmission.

[0067] In the embodiments of the present application, the second information is feedback information that the terminal feeds back to the node about the resources actually used by the terminal after the terminal requests resource allocation from the node and the node allocates multiple sets of quasi-orthogonal resources to the terminal.

[0068] The reporting method provided by the embodiments of the present application is such that the terminal reports first information for providing sidelink transmission information to a node or second information for providing an authorization index used for physical sidelink control channel / physical sidelink shared channel PSCCH / PSSCH transmission. In this way, the terminal reports at least one first reference signal resource index or first resource or resource set for providing sidelink transmission information to the node, or an authorization index for providing an authorization index used for physical sidelink control channel / physical sidelink shared channel PSCCH / PSSCH transmission, so that after the node receives at least one first reference signal resource index or first resource or resource set, or the authorization index reported by the terminal, the node schedules corresponding resources for the terminal, solves the limitation brought by sidelink support beam management to Mode 1 resource allocation, further improves resource utilization rate, and ensures that the base station schedules reliable communication resources for the transmitting UE.

[0069] Based on the foregoing embodiments, an embodiment of the present application provides a resource allocation method, which is applied to a node. The method includes step 201 or step 202:

[0070] Step 201: Receive first information.

[0071] The first information is used to provide sidelink transmission information to the node, and the first information includes at least one of the following:

[0072] At least one first reference signal resource index;

[0073] A first resource or a resource set.

[0074] In the embodiments of the present application, the node may be a service node for providing communication network services to the terminal, such as a base station or other service nodes. The node receives the first information reported by the terminal having a communication connection.

[0075] Step 202: Receive second information.

[0076] The second information is used to provide an authorization index used for physical sidelink control channel / physical sidelink shared channel PSCCH / PSSCH transmission.

[0077] In the embodiments of the present application, when the node provides transmission resources for the terminal and the terminal selects a resource from the received transmission resources for transmission, the terminal feeds back the second information of the selected resource to the node to assist the node in further improving resource utilization rate.

[0078] In the resource allocation method provided by the embodiments of the present application, a node receives first information for providing sidelink transmission information to the node or second information for providing an authorization index for physical sidelink control channel / physical sidelink shared channel PSCCH / PSSCH transmission from a terminal. In this way, the terminal reports at least one first reference signal resource index or first resource or resource set for providing sidelink transmission information to the node, or an authorization index for providing physical sidelink control channel / physical sidelink shared channel PSCCH / PSSCH transmission, so that after the node receives the at least one first reference signal resource index or first resource or resource set, or the authorization index reported by the terminal, the node schedules corresponding resources for the terminal, solves the limitation of sidelink support for beam management on Mode 1 resource allocation, further improves resource utilization, and ensures that the base station schedules reliable communication resources for the transmitting UE.

[0079] Based on the foregoing embodiments, an embodiment of the present application provides a method. As shown in Figure 1 the following, the method includes the following steps:

[0080] Step 301, the terminal reports first information.

[0081] The first information is used to provide sidelink transmission information to the node, and the first information includes at least one of the following:

[0082] At least one first reference signal resource index;

[0083] First resource or resource set.

[0084] In the embodiments of the present application, after the initial beam matching between the terminal and at least one other terminal ends, first information for requesting beam-based unicast service resources is generated based on the service resources between the terminal and at least one other terminal; the first information is sent to the base station.

[0085] Step 302, the node receives the first information.

[0086] The first information is used to provide sidelink transmission information to the node, and the first information includes at least one of the following:

[0087] At least one first reference signal resource index;

[0088] First resource or resource set.

[0089] In the embodiments of the present application, the node receives the first information reported by the terminal, and determines unicast service resources corresponding to the first information for the terminal based on the first information; so as to send the unicast service resources to the terminal subsequently. In this way, the terminal can perform resource transmission according to the unicast service resources sent by the node, ensuring resource utilization and practical reliability.

[0090] Based on the foregoing embodiments, in other embodiments of the present application, when the first information includes a first reference signal resource index, it includes:

[0091] At least one reported target group corresponds to a first reference signal resource index.

[0092] In an embodiment of the present application, after the initial beam matching between the terminal and at least one other terminal ends, receive at least one destination index sent by at least one other terminal to obtain at least one destination index; based on the at least one destination index, generate first information for requesting beam-based unicast service resources; send the first information to the base station; wherein, classify the at least one destination index according to the same reference signal resource index to obtain at least one set of classified indexes, that is, at least one reported target group, and each set of classified indexes corresponds to a first reference signal resource index; store each set of classified indexes in the first buffer status report (BSR), and store the corresponding first reference signal resource index in the index indication field where the first BSR increases, to obtain the first information.

[0093] Exemplarily, the sidelink proposed in the new radio (NR) standard R18 is for extended commercial use cases, such as applications in the implementation of virtual reality (VR) and augmented reality (AR), real-time video sharing, etc., to support services with higher data rates (Gbps). To support services with higher data rates, the R18 sidelink will study the enhancement on the authorized spectrum of frequency range 2 (FR2). The specific content is to support the beam management enhancement of unicast services in the FR2 authorized frequency band, including scenarios such as initial beam pairing, beam maintenance, and beam failure recovery. After the sidelink beam management, it will affect the existing Mode 1 resource selection mode.

[0094] The Mode 1 resource allocation mechanism is a base station-controlled resource allocation mode, where: it can be divided into Mode 1 dynamic resource allocation and Mode 1 grant-free resource allocation.

[0095] The specific time process of Mode 1 dynamic resource allocation can be as follows: The network dynamically allocates sidelink transmission resources for the terminal through Downlink Control Information (DCI). In the dynamic resource allocation mode, the terminal sends a Scheduling Request (SR) and a Buffer Status Report (BSR) to the network, and the network allocates sidelink transmission resources for the terminal according to the buffer status of the terminal.

[0096] Furthermore, to support the system transmission reliability requirements, the R16 sidelink introduces a Physical sidelink feedback channel (PSFCH), that is, the receiving end feeds back the reception of the Physical sidelink control channel / Physical sidelink shared channel (PSCCH / PSSCH) to the sending end. In the Mode 1 resource allocation mode, it supports the sidelink sending end to report the Hybrid Automatic Repeat request-ACKnowledgement (HARQ-ACK) information fed back by the receiving end to the network, so that the network can better schedule the retransmission resources.

[0097] To support dynamic resource allocation, the R16 sidelink designs a DCI format (DCI format 3_0), which can be used for dynamic resource allocation and can also be used for the activation or deactivation of grant-free resources. DCI format 3_0 mainly includes the following information:

[0098] Resource pool index: If the network configures multiple Mode 1 resource pools, this indication field is used to indicate the resource pool to which the scheduled sidelink transmission resources belong;

[0099] Sidelink resource indication information: The network can allocate N (1 ≤ N ≤ Nmax) sidelink transmission resources to the terminal, where Nmax = 2 or 3; specifically, it includes the following indication information: Time gap: The time slot interval between the first sidelink transmission resource and the time slot where the DCI is located; Lowest index of the subchannel allocation to the initial transmission: The lowest subchannel index occupied by the first sidelink transmission resource; FRIV: The same as the sidelink control information (SCI) format 1-A; It indicates the number of subchannels occupied by the sidelink transmission resources and the lowest subchannel index of the N - 1 resources other than the first sidelink transmission resource; TRIV: The same as the SCI format 1-A; It indicates the time slot interval of the N - 1 resources other than the first sidelink transmission resource relative to the first sidelink transmission resource.

[0100] PUCCH transmission resource indication information: The PUCCH resources used to configure the terminal to report sidelink HARQ-ACK information to the network.

[0101] HARQ process number: Used to indicate the HARQ process number corresponding to the sidelink transmission resources allocated by the network to the terminal.

[0102] NDI: Used to indicate new transmission or retransmission.

[0103] Configuration index: When DCI format 3_0 is used to activate or deactivate grant-free resources, this index is used to indicate the grant-free configuration activated or deactivated by this DCI.

[0104] Counter sidelink assignment index: Used to indicate the number of DCIs transmitted cumulatively by the network for scheduling sidelink transmission resources. The terminal determines the number of information bits when generating the HARQ-ACK codebook based on this information.

[0105] The structural schematic of the sidelink BSR can refer to Figure 2 As shown, for each target group, the carried content includes at least one destination index, one logical channel group (LCG) ID, and one buffer size.

[0106] The specific implementation process of Mode 1 license-free resource allocation can be as follows: When the terminal is configured with license-free resources, when sidelink data arrives, the terminal can use the license-free resources for transmission without re-applying for transmission resources from the network. Sidelink license-free resources are divided into two types: Type-I and Type-II. Among them: Type-I is used for the network to configure sidelink license-free transmission resources and parameters for the terminal through RRC signaling; Type-II is used for the network to configure partial sidelink license-free transmission parameters for the terminal, and activate or deactivate the sidelink license-free resources through DCI.

[0107] Correspondingly, when the R18 sidelink unicast service supports beam-based directional transceiver, as Figure 3 shown in the four application scenarios provided by the embodiments of the present application, including: Scenario a, UE1 transmits sidelink data to multiple UEs such as UE2 and UE3 using different beam directions; Scenario b, UE1 transmits sidelink data to multiple UEs such as UE2 and UE3 using the same beam direction; Scenario c, multiple adjacent UEs such as UE1 and UE2 transmit sidelink data using different beam directions respectively; Scenario d, multiple UEs such as UE1 and UE2 directionally transmit sidelink data to a UE such as UE3 or UE4, where UE UE3 receives data using different beams, and UE4 receives data using the same beam.

[0108] For scenarios a and b: After the sidelink transceiver UE completes the initial beam pairing, if the first terminal requests multicast or broadcast service resources from the base station as the transmitting terminal (Tx UE), the existing mechanism is reused; if the first terminal requests beam-based unicast service resources from the base station, Implementation Option 1 can be adopted: The first terminal classifies and reports the BSR according to the reference signal resource index, that is, the first terminal classifies the destination index fed back by other terminals according to the result of the initial beam pairing with other terminals, places the destination indexes belonging to the same reference signal resource index in a BSR for reporting, and adds a reference signal resource index indication field in the BSR. Correspondingly, the reference signal resource index is used for the receiving terminal (Rx UE) to measure the layer 1 reference signal receiving power (L1 Reference Signal Receiving Power / Reference Signal Received Power, L1-RSRP) or the layer 1 signal interference noise ratio (L1 Signal Interference Noise Ratio, L1-SINR). The reference signal can be the sidelink synchronization signal block (Sidelink-Synchronization Signal Block, S-SSB) or the direct link channel state information reference symbol (SideLink Channel State Information Reference Symbol, SL CSI-RS). Example 1: Suppose the first terminal (Tx UE) communicates with the second, third, and fourth terminals (receiving terminals, Rx UE) respectively in unicast. According to the beam pairing, the SL CSI-RS resource indexes (CSI-RS resource indicator, CRI) fed back by the second and fourth terminals are index 1, and the CRI fed back by the third terminal is index 4. When the first terminal requests transmission resources for the second, third, and fourth terminals from the base station, it reports the destination indexes of the second and fourth terminals in one BSR and carries CRI index 1, and reports the BSR of the third terminal separately and carries CRI index 4.

[0109] Based on the foregoing embodiments, in other embodiments of the present application, when the first information includes multiple first reference signal resource indexes, it includes:

[0110] Each reported target group contains a reference signal resource index field, and the reference signal resource index field is used to indicate the first reference signal resource index.

[0111] In an embodiment of the present application, after the initial beam matching between a terminal and at least one other terminal ends, a destination index sent by at least one other terminal is received to obtain at least one destination index. A corresponding reference signal resource index is obtained from each destination index, and the reference signal resource indexes corresponding to at least one destination index are stored in a corresponding BSR to obtain first information.

[0112] Exemplarily, for Figure 3 scenarios a and b in

[0113]

[0114] Based on the foregoing embodiments, in other embodiments of the present application, when the first information includes a first resource or a resource set, it includes:

[0115] Each reported target group includes at least: a type field and a resource field. The type field is used to indicate the type of the first resource or the type of the resource set, and the resource field is used to indicate the first resource or the resource set;

[0116] The type of the first resource is a recommended type or a non-recommended type, or the type of the resource set is a recommended type or a non-recommended type.

[0117] ​In an embodiment of the present application, after the initial beam matching between a first terminal and at least one other terminal ends, a candidate resource or a set of candidate resources sent by the at least one other terminal is received; wherein, the candidate resource of each other terminal is a recommended resource or a non-recommended resource, and similarly, each set of candidate resources may also belong to the recommended resource type or the non-recommended resource type; determine the resource type of each set of candidate resources; generate a BSR corresponding to each other terminal; store the resource type and the set of candidate resources corresponding to each other terminal into the corresponding BSR to obtain first information; send the first information to a node.

[0118] Exemplarily, for Figure 3 the scenarios a, b, c, and d shown in, the Rx UE provides the Tx UE with a recommended set of candidate resources S1 or a non-recommended set of candidate resources S2 based on the beam perception result. The Tx UE reports the recommended set of candidate resources or the non-recommended set of candidate resources to the base station based on the feedback of each target, that is, each Rx UE. That is to say, for each target, the Tx UE reports the following: a target index, an LCG ID, a buffer size, a candidate resource type indication (used to indicate a recommended candidate resource or a non-recommended candidate resource), and a set of candidate resources, etc. It should be noted that since the Rx UE needs to blindly detect PSCCH and SCI format2-A / B / C on all Rx resource pools, the reserved resource situation of other UEs in the receiving direction can be obtained. Thus, the Rx UE can provide the Tx UE with a recommended set of candidate resources S1 or a non-recommended set of candidate resources S2. Among them, when the Rx UE provides the Tx UE with a recommended set of candidate resources S1 or a non-recommended set of candidate resources S2, it can be provided actively by the Rx UE or passively provided by the Rx UE, that is, the Rx UE provides it after receiving a request sent by the Tx UE for the Rx UE to provide a recommended or non-recommended resource set. Example 3: The first terminal and the second terminal perform unicast communication, and the third terminal and the fourth terminal perform unicast communication. The first terminal and the third terminal respectively report the recommended set of candidate resources to the base station. If there are many overlapping resources in the recommended sets of candidate resources reported by the first terminal and the third terminal to the base station, the base station can determine the time-frequency domain resources that the first terminal and the third terminal can perform spatial division multiplexing on and preferentially provide the same time-frequency domain resources for the two to improve resource utilization.

[0119] It should be noted that the descriptions of the same steps and the same content in this embodiment and other embodiments can refer to the descriptions in other embodiments and will not be repeated here.

[0120] In the method provided by the embodiment of the present application, the terminal reports first information for providing direct link transmission information to the node, and the node receives the first information. In this way, the terminal processes the reporting of at least one first reference signal resource index or first resource or resource set for providing direct link transmission information to the node, so that after the node receives the at least one first reference signal resource index or first resource or resource set reported by the terminal, the node schedules corresponding resources for the terminal, solves the limitation of sidelink support for beam management on Mode 1 resource allocation, further improves resource utilization rate, and ensures that the base station schedules reliable communication resources for the sending UE.

[0121] Based on the foregoing embodiment, the embodiment of the present application provides a method. Referring to Figure 4 as shown, the method includes the following steps:

[0122] Step 401: The terminal reports second information.

[0123] The second information is used to provide an authorization index for physical direct link control channel / physical direct link shared channel PSCCH / PSSCH transmission.

[0124] In the embodiment of the present application, the second information reported by the terminal is information of the transmission resource of the resource selected by the terminal from the resources allocated by the node for transmitting the resource to other terminals.

[0125] Step 402: The node receives the second information.

[0126] The second information is used to provide an authorization index for physical direct link control channel / physical direct link shared channel PSCCH / PSSCH transmission.

[0127] In the embodiment of the present application, the node receives the second information reported by the terminal for subsequent management of the resources corresponding to the second information, and improves the utilization rate of the resources corresponding to the second information.

[0128] Based on the foregoing embodiment, in other embodiments of the present application, referring to Figure 5 as shown, before the node executes step 402, it is further used to execute step 403:

[0129] Step 403: The node allocates at least one set of type 1 configured grant, type 2 configured grant, and dynamic grant resources.

[0130] In the embodiments of the present application, the type 1 configured grant is used to indicate that it takes effect immediately after configuration, and can be denoted as type 1 resource; the type 2 configured grant is used to indicate that after configuration, the node sends an activation message through DCI format 3_0 and it takes effect after activation, and can be denoted as type 2 resource; the dynamic grant resource is multiple sets of periodic resources configured by the node for the terminal, which can be denoted as dynamic grant, or can also be referred to as multiple sets of orthogonal transmission resources.

[0131] The node performs configured grant for the terminal and allocates at least one set of resources to the terminal, where the resources at least include type 1 configured grant, type 2 configured grant, and dynamic grant resource.

[0132] Among them, for the dynamic grant, it can be that after the first terminal sends a scheduling request and a buffer status report to the base station, the base station dynamically schedules resources for the terminal.

[0133] Correspondingly, before the terminal executes step 401, it is also used to execute step 404:

[0134] Step 404: The terminal receives at least one set of type 1 configured grant, type 2 configured grant, and dynamic grant resource.

[0135] In the embodiments of the present application, the terminal receives at least one set of type 1 configured grant, type 2 configured grant, and dynamic grant resource allocated by the node for it, and determines a set of resources for resource transmission according to the at least one set of type 1 configured grant, type 2 configured grant, and dynamic grant resource.

[0136] Based on the foregoing embodiments, the embodiments of the present application provide an implementation method. For Figure 3 the scenarios a, b, c, and d shown in, after the initial beam matching ends between the terminal and at least one other terminal, the terminal sends request information for requesting transmission resources to the base station; after receiving the request information, the base station allocates multiple sets of orthogonal transmission resources including at least type 1 resources, type 2 resources, and dynamic grant resources to the terminal.
