Resource scheduling methods, terminals, and base stations for direct links

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411213570.9, filed in China on August 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of communication technology, specifically relating to a resource scheduling method, terminal, and base station for a direct link. Background Technology

[0004] Currently, the New Radio (NR) Sidelink (SL) supports two resource allocation methods: Mode 1, based on base station scheduling, and Mode 2, autonomous resource selection. Regardless of the method, both rely on the SL user equipment (UE) operating in Frequency Range 1 (FR1). SL UE transmission and reception are omnidirectional. Therefore, in Mode 1, the base station allocates transmission resources to the transmitting UE, which then uses omnidirectional beams to transmit. The receiving UE simply uses omnidirectional beams to receive; the receiving UE does not need to know the transmitting UE's transmission time in advance. However, in the FR2 band, due to the millimeter-wave channel characteristics of high-frequency carriers, signal transmission loss is high and penetration is poor. To improve signal transmission distance, beamforming technology is required. This means the UE can only perform sensing, receiving, and transmitting in a specific beam direction, and can only use one specific beam for sensing, receiving, or transmitting at a time. However, based on beamforming, if the receiving UE does not know the location of the transmission resources allocated to the transmitting UE by the base station, it will not know which transmission resource to use for reception, making normal communication with the transmitting UE impossible. Summary of the Invention

[0005] This application provides a resource scheduling method, terminal, and base station for a direct link, which can solve the problem that the receiving terminal cannot communicate normally with the sending terminal because the receiving terminal does not know the time and location of the transmission resources allocated by the base station to the sending terminal.

[0052] The resource scheduling of the direct link provided in this application embodiment will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0053] As shown in Figure 2, this application embodiment provides a resource scheduling method for a direct link, applied to a base station. The method specifically includes the following steps:

[0054] Step 201: Determine the scheduling information of the direct link SL transmission resources, and send the scheduling information to the first terminal and the second terminal;

[0055] The scheduling information includes first scheduling information, which is sent to the first terminal and the second terminal. The first scheduling information is used to indicate the target SL transmission resources allocated to the first terminal and to indicate to the second terminal the target SL transmission resources used by the target information sent by the first terminal.

[0056] Alternatively, the scheduling information includes the first scheduling information and the second scheduling information. The first scheduling information is sent to the first terminal, and the second scheduling information is sent to the second terminal. The first scheduling information is used to indicate the target SL transmission resources allocated to the first terminal, and the second scheduling information is used to indicate to the second terminal the target SL transmission resources used by the target information sent by the first terminal.

[0057] It should be noted that both the first terminal and the second terminal are in Radio Resource Control (RRC) connection mode, and the first terminal and the second terminal have exchanged their respective terminal identification information. When the terminal identification information of one of them is updated, the first terminal and the second terminal need to exchange their respective terminal identification information again.

[0058] The target SL transport resource can be a one-time transport resource or a transport resource with multiple periods of configured authorization.

[0059] In this embodiment, the base station determines the scheduling information of the direct link SL transmission resources. The scheduling information includes first scheduling information. The base station then sends the first scheduling information to the first terminal and the second terminal. The first scheduling information is used to indicate the target SL transmission resources allocated to the first terminal and to indicate to the second terminal the target SL transmission resources used by the target information sent by the first terminal. That is, the first terminal acts as the sending terminal and the second terminal acts as the receiving terminal. The base station sends the first scheduling information of the SL transmission resources to the sending terminal and the receiving terminal. Thus, the sending terminal knows the target SL transmission resources allocated by the base station for sending target information, and the receiving terminal knows the target SL transmission resources used by the sending terminal to transmit target information. The sending terminal transmits target information on the target SL transmission resources, and the receiving terminal receives target information on the target SL transmission resources, ensuring the reliability of communication between the sending terminal and the receiving terminal.

[0060] Alternatively, the base station determines the scheduling information for the direct link SL transmission resources. This scheduling information includes the first scheduling information and the second scheduling information. The base station then sends the first scheduling information to the first terminal and the second scheduling information to the second terminal. The first scheduling information indicates the target SL transmission resource allocated to the first terminal, and the second scheduling information indicates to the second terminal the target SL transmission resource used by the target information sent by the first terminal. That is, the first terminal acts as the sending terminal, and the second terminal acts as the receiving terminal. The base station sends the first scheduling information for the SL transmission resources to the sending terminal and the second scheduling information to the receiving terminal. Thus, the sending terminal learns about the target SL transmission resource allocated by the base station for sending target information through the first scheduling information, and the receiving terminal learns about the target SL transmission resource for transmitting target information through the second scheduling information. The sending terminal transmits target information on the target SL transmission resource, and the receiving terminal receives target information on the target SL transmission resource, ensuring the reliability of communication between the sending terminal and the receiving terminal.

[0061] The resource scheduling method for the above-mentioned direct link will be described in detail below through specific embodiments:

[0062] Example 1

[0063] Step 201, which determines the scheduling information for the direct link SL transmission resources and sends the scheduling information to the first terminal and the second terminal, specifically includes:

[0064] Upon receiving a resource scheduling request and / or cache status report sent by the first terminal, the first scheduling information is determined based on the resource scheduling request and / or the cache status report;

[0065] Based on the terminal identification information of the first terminal, the first scheduling information is sent to the first terminal and the second terminal.

[0066] Specifically, the first terminal sends a resource scheduling request and / or cache status report to the base station, requesting the scheduling of SL transmission resources through the resource scheduling request and / or cache status report. The base station determines the first scheduling information based on the received resource scheduling request and / or cache status report. Since both the first and second terminals are in RRC connected state, and the first and second terminals have exchanged their respective terminal identification information, the base station sends the first scheduling information to both the first and second terminals based on the first terminal's terminal identification information. Thus, the first terminal learns from the first scheduling information the target SL transmission resources allocated by the base station for transmitting target information, and the second terminal learns from the first scheduling information the target SL transmission resources for transmitting target information. The first terminal transmits the target information on the target SL transmission resources, and the second terminal receives the target information on the target SL transmission resources, ensuring the reliability of communication between the first and second terminals.

[0067] It should be noted that the first scheduling information can be carried through downlink control information (DCI) signaling.

[0068] Example 1: The first terminal sends a resource scheduling request to the base station, requesting the scheduling of SL transmission resources. The base station determines the first scheduling information based on the received resource scheduling request, and sends the first scheduling information to the first terminal and the second terminal based on the terminal identification information of the first terminal.

[0069] Example 2: The first terminal sends a resource scheduling request and a buffer status report to the base station. The first terminal requests the base station to schedule SL transmission resources based on the resource scheduling request and buffer status report. The base station determines the first scheduling information based on the received resource scheduling request and buffer status report, and then sends the first scheduling information to both the first terminal and the second terminal based on the terminal identification information of the first terminal.

[0070] Furthermore, the first scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, first physical uplink control channel (PUCCH) resource indication information, Hybrid Automatic Repeat reQuest (HARQ) process number, new data indication, configuration index, and cumulative sideline authorization index.

[0071] The SL transmission resource indication includes, but is not limited to, at least one of the following: time-domain resource offset, time-domain resource allocation, frequency-domain resource allocation, and starting sub-channel index.

[0072] The first PUCCH resource indication information is the PUCCH resource index.

[0073] Furthermore, the first scheduling information may also include: second PUCCH resource indication information and third PUCCH resource indication information. After decoding the first scheduling information, the first terminal sends an acknowledgment (ACK) feedback to the base station on the resource indicated by the second PUCCH resource indication information. After decoding the first scheduling information, the second terminal sends an ACK feedback to the base station on the resource indicated by the third PUCCH resource indication information. Then, the base station sends an acknowledgment message to the first terminal. After receiving the acknowledgment message, the first terminal sends the target information on the target SL transmission resource confirmed according to the decoded first scheduling information.

[0074] Example 2

[0075] Step 201, which determines the scheduling information for the direct link SL transmission resources and sends the scheduling information to the first terminal and the second terminal, specifically includes:

[0076] Upon receiving a resource scheduling request and / or cache status report sent by the first terminal, the first scheduling information and the second scheduling information are determined based on the resource scheduling request and / or the cache status report.

[0077] Based on the terminal identification information of the first terminal, the first scheduling information is sent to the first terminal;

[0078] The second scheduling information is sent to the second terminal based on the terminal identification information of the second terminal, where the terminal identification information of the second terminal is sent by the first terminal.

[0079] Specifically, the first terminal sends the resource scheduling request and / or the cache status report to the base station. The base station determines first scheduling information and second scheduling information based on the received resource scheduling request and / or cache status report. The base station sends the first scheduling information to the first terminal based on its terminal identification information, and the first terminal decodes the first scheduling information based on its terminal identification information. Furthermore, the first terminal also sends the terminal identification information of the second terminal to the base station. The base station sends the second scheduling information to the second terminal based on the received second terminal identification information, and the second terminal decodes the second scheduling information based on its terminal identification information. Thus, the first terminal learns from the decoded first scheduling information the target SL transmission resource allocated by the base station for transmitting target information, and the second terminal learns from the decoded second scheduling information the target SL transmission resource for transmitting target information. The first terminal transmits target information on the target SL transmission resource, and the second terminal receives target information on the target SL transmission resource, ensuring reliable communication between the first and second terminals.

[0080] It should be noted that the first and second scheduling information can be carried through DCI signaling.

[0081] Furthermore, the first scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, first PUCCH resource indication information, HARQ process number, new data indication, configuration index, and cumulative sideline authorization index.

[0082] The SL transmission resource indication includes, but is not limited to, at least one of the following: time-domain resource offset, time-domain resource allocation, frequency-domain resource allocation, and starting sub-channel index.

[0083] The first PUCCH resource indication information is the PUCCH resource index.

[0084] Furthermore, the second scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, configuration index, and receive resource indication.

[0085] Furthermore, the first scheduling information may also include second PUCCH resource indication information. After decoding the first scheduling information, the first terminal sends an ACK feedback to the base station on the resource indicated by the second PUCCH resource indication information.

[0086] The second scheduling information may further include: third PUCCH resource indication information. After decoding the second scheduling information, the second terminal sends an ACK feedback to the base station on the resource indicated by the third PUCCH resource indication information. Then, the base station sends an acknowledgment message to the first terminal. After receiving the acknowledgment message, the first terminal sends the target information on the target SL transmission resource confirmed according to the decoded first scheduling information.

[0087] Example 3

[0088] After determining the scheduling information of the direct link SL transmission resources in step 201 and sending the scheduling information to the first terminal and the second terminal, the method further includes:

[0089] If a Transmission Configuration Indicator (TCI) status information sent by the first terminal is received before the first SL transmission resource, then the TCI status information and / or the terminal identification information of the first terminal are sent to the second terminal.

[0090] Specifically, based on the above embodiments one and two, after the first terminal decodes the first scheduling information, it sends TCI status information to the base station. If the base station receives the TCI status information sent by the first terminal before the first SL transmission resource, it sends the TCI status information and / or the terminal identification information of the first terminal to the second terminal.

[0091] The TCI status information includes, but is not limited to: Quasi Co-Location (QCL) type configuration and reference signal resource indication.

[0092] Example 4

[0093] Step 201, which determines the scheduling information for the direct link SL transmission resources and sends the scheduling information to the first terminal and the second terminal, specifically includes:

[0094] Step 2011: Determine the first scheduling information and send the first scheduling information to the first terminal;

[0095] Step 2012: Upon receiving the configuration authorization index used by the first terminal for communication between the first terminal and the second terminal from the first terminal, determine the second scheduling information based on the configuration authorization index used by the first terminal for communication between the second terminal;

[0096] Based on the terminal identification information of the second terminal, the second scheduling information and / or the terminal identification information of the first terminal are sent to the second terminal, wherein the terminal identification information of the second terminal is sent by the first terminal.

[0097] Specifically, the base station determines first scheduling information and sends it to the first terminal. The first terminal then uses this information to determine the target SL transmission resources (i.e., target configuration authorization resources) allocated by the base station for transmitting target information within each configuration authorization period. Upon receiving the first scheduling information, the first terminal sends the configuration authorization index used for communication between itself and the second terminal to the base station. The base station determines second scheduling information based on this index. Furthermore, the first terminal sends the terminal identification information of the second terminal to the base station. The base station then sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal based on the received terminal identification information. The second terminal decodes the second scheduling information based on its terminal identification information and determines the target SL transmission resources used by the first terminal to transmit target information within each configuration authorization period. Thus, the first terminal transmits target information on the target SL transmission resources within each configuration authorization period, and the second terminal receives target information on the target SL transmission resources within each configuration authorization period, ensuring reliable communication between the first and second terminals.

[0098] It should be noted that the first and second scheduling information can be carried through RRC signaling.

[0099] Furthermore, the first scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, configuration authorization index, configuration authorization period, number of HARQ processes, HARQ process number offset, maximum number of transmissions using configuration authorization, and second PUCCH resource indication information;

[0100] The second PUCCH resource indication information includes, but is not limited to, at least one of the following: PUCCH resource index, the time interval between the physical side link feedback channel PSFCH and PUCCH.

[0101] The SL transmission resource indication includes, but is not limited to, at least one of the following: time-domain resource offset, time-domain resource allocation, frequency-domain resource allocation, and starting sub-channel index.

[0102] Furthermore, the second scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, and configuration authorization period.

[0103] Furthermore, the second scheduling information may also include third PUCCH resource indication information. After the base station sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal, the second terminal sends an ACK feedback to the base station on the resource indicated by the third PUCCH resource indication information. Then the base station sends an acknowledgment message to the first terminal. After receiving the acknowledgment message, the first terminal sends the target information on the target SL transmission resource (i.e., the target configuration authorized resource) confirmed according to the first scheduling information.

[0104] Example 5

[0105] Before determining the second scheduling information based on the configuration authorization index used for communication between the first terminal and the second terminal, upon receiving the configuration authorization index sent by the first terminal, step 2012 further includes:

[0106] Downlink Control Information (DCI) activation signaling is sent to the first terminal, and the DCI activation signaling is used to activate the target SL transmission resource.

[0107] Specifically, the base station determines first scheduling information and sends it to the first terminal. The first terminal then uses this first scheduling information to determine the target SL transmission resources (i.e., target configuration authorization resources) allocated by the base station for transmitting target information within each configuration authorization period. After sending the first scheduling information to the first terminal, the base station sends a DCI activation signaling message to the first terminal. This DCI activation signaling message is used to activate the target SL transmission resources (i.e., target configuration authorization resources). After receiving the DCI activation signaling message, the first terminal sends the configuration authorization index used for communication between the first terminal and the second terminal to the base station. The base station determines second scheduling information based on the configuration authorization index used for communication between the first terminal and the second terminal. The first terminal also sends the terminal identification information of the second terminal to the base station. The base station sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal based on the received terminal identification information of the second terminal. The second terminal decodes the second scheduling information based on its terminal identification information and determines the target SL transmission resources used by the first terminal for transmitting target information within each configuration authorization period based on the decoded second scheduling information. Thus, the first terminal transmits target information on the target SL transmission resources within each configuration authorization period, and the second terminal receives target information on the target SL transmission resources within each configuration authorization period, ensuring the reliability of communication between the first terminal and the second terminal.

[0108] It should be noted that the first and second scheduling information can be carried through RRC signaling.

[0109] Furthermore, the first scheduling information includes, but is not limited to, at least one of the following: resource pool index, configuration authorization index, configuration authorization period, number of HARQ processes, HARQ process number offset, and maximum number of transmissions using configuration authorization.

[0110] The second scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, and configuration authorization period.

[0111] DCI activation signaling includes, but is not limited to: resource pool index, SL transport resource indication, second PUCCH resource indication information, HARQ process number, new data indication, configuration authorization index, and cumulative sideline authorization index.

[0112] The SL transmission resource indication includes, but is not limited to, at least one of the following: time-domain resource offset, time-domain resource allocation, frequency-domain resource allocation, and starting sub-channel index.

[0113] Furthermore, the second scheduling information may also include third PUCCH resource indication information. After the base station sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal, the second terminal sends an ACK feedback to the base station on the resource indicated by the third PUCCH resource indication information. Then the base station sends an acknowledgment message to the first terminal, and after receiving the acknowledgment message, the first terminal sends the target information on the target SL transmission resource (i.e., the target configuration authorized resource) confirmed according to the first scheduling information.

[0114] Example 6

[0115] After determining the scheduling information of the direct link SL transmission resources in step 201 and sending the scheduling information to the first terminal and the second terminal, the method further includes:

[0116] If the TCI status information sent by the first terminal is received before the first SL transmission resource in each configuration authorization cycle, then the TCI status information and / or the terminal identification information of the first terminal are sent to the second terminal.

[0117] The TCI status information includes at least one of the following: quasi-co-address QCL type configuration and reference signal resource indication.

[0118] Specifically, based on the above embodiments four and five, before determining the target SL transmission resource in each configuration authorization period according to the first scheduling information, the first terminal sends TCI status information to the base station in each configuration authorization period. If the base station receives the TCI status information sent by the first terminal before the first SL transmission resource in each configuration authorization period, it sends the TCI status information and / or the terminal identification information of the first terminal to the second terminal, so that the second terminal determines the target beam used to receive the target information on the target SL transmission resource in each configuration authorization period according to the TCI status information.

[0119] The TCI status information includes, but is not limited to: QCL type configuration and reference signal resource indication.

[0120] Example: As shown in Figure 3, each configuration grant period has configuration grant resources (i.e., SL transmission resources) R1, R2, and R3. Before the first configuration grant resource R1 in each configuration grant period, the first terminal sends TCI status information to the base station through PUCCH1. Then, the base station sends TCI status information to the second terminal through the Physical Downlink Control Channel (PDCCH). For example, in the first configuration grant period, the first terminal sends TCI status information to the base station through PUCCH1, and then the base station sends TCI status information to the second terminal through PDCCH1.

[0121] TCI status information can also be carried using other channels, and no specific restrictions are made here.

[0122] In summary, in this embodiment, the base station determines the scheduling information of the direct link (SL) transmission resources and sends the scheduling information to the first terminal and the second terminal. The first terminal learns from the scheduling information the target SL transmission resources allocated by the base station for transmitting target information, and the second terminal learns from the scheduling information the target SL transmission resources for transmitting target information by the first terminal. The first terminal transmits target information on the target SL transmission resources, and the second terminal receives target information on the target SL transmission resources, ensuring the communication reliability between the first and second terminals. In addition, the first terminal also sends beam-related TCI status information to the base station, and the base station forwards the TCI status information to the second terminal, so that the second terminal can determine the appropriate target beam to receive the target message based on the TCI status information, further improving the communication reliability between the first and second terminals.

[0123] The resource scheduling method for direct links in a base station provided in this application can be executed by a resource scheduling device for direct links in a base station.

[0124] As shown in Figure 4, this application embodiment also provides a resource scheduling device 400 for a direct link, applied to a base station, including:

[0125] The first processing module 401 is used to determine the scheduling information of the direct link SL transmission resources and send the scheduling information to the first terminal and the second terminal.

[0126] The scheduling information includes first scheduling information, which is sent to the first terminal and the second terminal.

[0138] Based on the terminal identification information of the second terminal, the second scheduling information and / or the terminal identification information of the first terminal are sent to the second terminal, wherein the terminal identification information of the second terminal is sent by the first terminal.

[0139] Optionally, before the first processing module 401 determines the second scheduling information based on the configuration authorization index used for communication between the first terminal and the second terminal, upon receiving the configuration authorization index sent by the first terminal, it is further configured to:

[0140] Downlink Control Information (DCI) activation signaling is sent to the first terminal, and the DCI activation signaling is used to activate the target SL transmission resource.

[0141] Optionally, the device further includes:

[0142] The first sending module is configured to, if it receives Transmission Configuration Indication (TCI) status information from the first terminal before the first SL transmission resource, send the TCI status information and / or the terminal identification information of the first terminal to the second terminal; or,

[0143] If the TCI status information sent by the first terminal is received before the first SL transmission resource in each configuration authorization cycle, then the TCI status information and / or the terminal identification information of the first terminal are sent to the second terminal.

[0148] In summary, in this embodiment, the base station determines the scheduling information of the direct link (SL) transmission resources and sends the scheduling information to the first terminal and the second terminal. The first terminal learns from the scheduling information the target SL transmission resources allocated by the base station for transmitting target information, and the second terminal learns from the scheduling information the target SL transmission resources for transmitting target information by the first terminal. The first terminal transmits target information on the target SL transmission resources, and the second terminal receives target information on the target SL transmission resources, ensuring the communication reliability between the first and second terminals. In addition, the first terminal also sends beam-related TCI status information to the base station, and the base station forwards the TCI status information to the second terminal, so that the second terminal can determine the appropriate target beam to receive the target message based on the TCI status information, further improving the communication reliability between the first and second terminals.

[0149] The resource scheduling device for direct links in base stations provided in this application embodiment can implement the various processes implemented in the method embodiments of Figures 1 to 3 and achieve the same technical effect. To avoid repetition, it will not be described again here.

[0150] As shown in Figure 5, this application embodiment also provides a resource scheduling method for a direct link, applied to a first terminal. The method specifically includes the following steps:

[0151] Step 501: Receive the first scheduling information sent by the base station;

[0152] Step 502: Determine the target SL transmission resource based on the first scheduling information, and send the target information on the target SL transmission resource; or, determine the target SL transmission resource within each configuration authorization period based on the first scheduling information, and send the target information on the target SL transmission resource within each configuration authorization period.

[0153] In this embodiment of the application, the base station sends first scheduling information to the first terminal. The first scheduling information is used by the base station to allocate target SL transmission resources to the first terminal. The first terminal can know the target SL transmission resources allocated by the base station for sending target information according to the received first scheduling information. Then, the first terminal sends the target message on the target SL transmission resources to ensure the reliability of communication between the first terminal and other receiving terminals.

[0154] Alternatively, the base station sends first scheduling information to the first terminal. This first scheduling information is used by the base station to allocate target SL transmission resources to the first terminal within each configuration authorization period. The first terminal can know the target SL transmission resources allocated by the base station within each configuration authorization period based on the received first scheduling information. Then, the first terminal sends target messages on the target SL transmission resources within each configuration authorization period to ensure the reliability of communication between the first terminal and other receiving terminals.

[0155] The resource scheduling method for the above-mentioned direct link will be described in detail below through specific embodiments:

[0156] Example 1

[0157] Before receiving the first scheduling information sent by the base station in step 501, the method further includes:

[0158] Send resource scheduling requests and / or cache status reports to the base station.

[0159] Specifically, the first terminal sends a resource scheduling request and / or cache status report to the base station, requesting the scheduling of SL transmission resources through the resource scheduling request and / or cache status report. This allows the base station to determine first scheduling information based on the received resource scheduling request and / or cache status report. Since both the first and second terminals are in RRC connected state and have exchanged their respective terminal identification information, the base station sends the first scheduling information to the first terminal based on the first terminal's terminal identification information. The first terminal decodes the first scheduling information based on its own terminal identification information and determines the target SL transmission resource or the target SL transmission resource within each configuration authorization period based on the decoded first scheduling information.

[0160] It should be noted that the first scheduling information can be carried through DCI signaling.

[0161] Example 1: The first terminal sends a resource scheduling request to the base station. The first terminal requests the base station to schedule SL transmission resources through the resource scheduling request, so that the base station determines the first scheduling information based on the received resource scheduling request. The base station sends the first scheduling information to the first terminal based on the terminal identification information of the first terminal.

[0162] Example 2: The first terminal sends a resource scheduling request and a cache status report to the base station. The first terminal requests the base station to schedule SL transmission resources through the resource scheduling request and cache status report, so that the base station determines the first scheduling information based on the received resource scheduling request and cache status report. The base station sends the first scheduling information to the first terminal based on the terminal identification information of the first terminal.

[0163] Furthermore, the first scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, first PUCCH resource indication information, HARQ process number, new data indication, configuration index, and cumulative sideline authorization index.

[0164] The SL transmission resource indication includes, but is not limited to, at least one of the following: time-domain resource offset, time-domain resource allocation, frequency-domain resource allocation, and starting sub-channel index.

[0165] The first PUCCH resource indication information is the PUCCH resource index.

[0166] Furthermore, the first scheduling information may also include: second PUCCH resource indication information and third PUCCH resource indication information. After decoding the first scheduling information, the first terminal sends an ACK feedback to the base station on the resource indicated by the second PUCCH resource indication information. After decoding the first scheduling information, the second terminal sends an ACK feedback to the base station on the resource indicated by the third PUCCH resource indication information. Then, the base station sends an acknowledgment message to the first terminal. After receiving the acknowledgment message, the first terminal sends the target information on the target SL transmission resource confirmed according to the decoded first scheduling information.

[0167] Example 2

[0168] The method further includes:

[0169] Send the terminal identification information of the second terminal to the base station, and send a resource scheduling request and / or a cache status report to the base station.

[0170] Specifically, the first terminal sends the terminal identification information of the second terminal to the base station, as well as the resource scheduling request and / or the cache status report, so that the base station determines the second scheduling information based on the received resource scheduling request and / or cache status report. The base station sends the second scheduling information to the second terminal based on the terminal identification information of the second terminal, and the second terminal decodes the second scheduling information based on the terminal identification information of the second terminal. Thus, the second terminal knows the target SL transmission resource for transmitting target information by the first terminal through the decoded second scheduling information. The first terminal transmits the target information on the target SL transmission resource, and the second terminal receives the target information on the target SL transmission resource, ensuring the reliability of communication between the first terminal and the second terminal.

[0171] It should be noted that before receiving the first scheduling information sent by the base station, the first terminal sends a resource scheduling request and a cache status report to the base station. Before or after receiving the first scheduling information sent by the base station, the second terminal sends its terminal identification information to the base station.

[0172] It should be noted that the first and second scheduling information can be carried through DCI signaling.

[0173] Furthermore, the first scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, first PUCCH resource indication information, HARQ process number, new data indication, configuration index, and cumulative sideline authorization index.

[0174] The SL transmission resource indication includes, but is not limited to, at least one of the following: time-domain resource offset, time-domain resource allocation, frequency-domain resource allocation, and starting sub-channel index.

[0175] The first PUCCH resource indication information is the PUCCH resource index.

[0176] Furthermore, the second scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, configuration index, and receive resource indication.

[0177] Furthermore, the first scheduling information may also include second PUCCH resource indication information. After decoding the first scheduling information, the first terminal sends an ACK feedback to the base station on the resource indicated by the second PUCCH resource indication information.

[0178] The second scheduling information may further include: third PUCCH resource indication information. After decoding the second scheduling information, the second terminal sends an ACK feedback to the base station on the resource indicated by the third PUCCH resource indication information. Then, the base station sends an acknowledgment message to the first terminal. After receiving the acknowledgment message, the first terminal sends the target information on the target SL transmission resource confirmed according to the decoded first scheduling information.

[0179] Example 3

[0180] Before step 502, which determines the target SL transmission resource based on the first scheduling information and sends the target information on the target SL transmission resource, the method further includes:

[0181] Before the first SL transmission resource, TCI status information is sent to the base station, and the TCI status information includes at least one of the following: QCL type configuration and reference signal resource indication.

[0182] Specifically, based on the above embodiments one and two, after the first terminal decodes the first scheduling information, the first terminal sends TCI status information to the base station before the first SL transmission resource. After the base station receives the TCI status information sent by the first terminal before the first SL transmission resource, the base station sends the TCI status information and / or the terminal identification information of the first terminal to the second terminal.

[0183] The TCI status information includes, but is not limited to: QCL type configuration and reference signal resource indication.

[0184] Example 4

[0185] After receiving the first scheduling information sent by the base station in step 501, the method further includes:

[0186] Step 503: Send the terminal identification information of the second terminal and / or the configuration authorization index used by the first terminal to communicate with the second terminal to the base station.

[0187] Specifically, the base station determines first scheduling information and sends it to the first terminal. The first terminal then uses this information to determine the target SL transmission resources (i.e., target configuration authorization resources) allocated by the base station for transmitting target information within each configuration authorization period. Upon receiving the first scheduling information, the first terminal sends the terminal identification information of the second terminal and / or the configuration authorization index used by the first terminal for communication with the second terminal to the base station. This allows the base station to determine second scheduling information based on the configuration authorization index used by the first terminal for communication with the second terminal. The base station then sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal based on the terminal identification information of the second terminal. This allows the second terminal to decode the second scheduling information based on its own terminal identification information and determine the target SL transmission resources used by the first terminal for transmitting target information within each configuration authorization period based on the decoded second scheduling information. Thus, the first terminal transmits target information on the target SL transmission resources within each configuration authorization period, and the second terminal receives target information on the target SL transmission resources within each configuration authorization period, ensuring reliable communication between the first and second terminals.

[0188] It should be noted that the first and second scheduling information can be carried through RRC signaling.

[0189] Furthermore, the first scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, configuration authorization index, configuration authorization period, number of HARQ processes, HARQ process number offset, maximum number of transmissions using configuration authorization, and second PUCCH resource indication information;

[0190] The second PUCCH resource indication information includes, but is not limited to, at least one of the following: PUCCH resource index, the time interval between the physical side link feedback channel PSFCH and PUCCH.

[0191] The SL transmission resource indication includes, but is not limited to, at least one of the following: time-domain resource offset, time-domain resource allocation, frequency-domain resource allocation, and starting sub-channel index.

[0192] Furthermore, the second scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, and configuration authorization period.

[0193] Furthermore, the second scheduling information may also include third PUCCH resource indication information. After the base station sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal, the second terminal sends an ACK feedback to the base station on the resource indicated by the third PUCCH resource indication information. Then the base station sends an acknowledgment message to the first terminal, and after receiving the acknowledgment message, the first terminal sends the target information on the target SL transmission resource (i.e., the target configuration authorized resource) confirmed according to the first scheduling information.

[0194] Example 5

[0195] Before step 503, which sends the terminal identification information of the second terminal and / or the configuration authorization index used by the first terminal to communicate with the second terminal to the base station, the method further includes:

[0196] The base station sends a DCI activation signaling message, which is used to activate the target SL transmission resource.

[0197] Specifically, the base station determines first scheduling information and sends it to the first terminal. The first terminal then uses this first scheduling information to determine the target SL transmission resources (i.e., target configuration authorization resources) allocated by the base station for transmitting target information within each configuration authorization period. After sending the first scheduling information to the first terminal, the base station sends a DCI activation signaling message to the first terminal. This DCI activation signaling message is used to activate the target SL transmission resources (i.e., target configuration authorization resources). Upon receiving the DCI activation signaling message, the first terminal sends the terminal identification information of the second terminal and / or the configuration authorization index used by the first terminal for communication with the second terminal to the base station. This allows the base station to determine second scheduling information based on the configuration authorization index used by the first terminal for communication with the second terminal. The base station then sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal based on the terminal identification information of the second terminal. The second terminal decodes the second scheduling information based on its own terminal identification information and determines the target SL transmission resources used by the first terminal for transmitting target information within each configuration authorization period based on the decoded second scheduling information. Thus, the first terminal transmits target information on the target SL transmission resources within each configuration authorization period, and the second terminal receives target information on the target SL transmission resources within each configuration authorization period, ensuring the reliability of communication between the first terminal and the second terminal.

[0198] It should be noted that the first and second scheduling information can be carried through RRC signaling.

[0199] Furthermore, the first scheduling information includes, but is not limited to, at least one of the following: resource pool index, configuration authorization index, configuration authorization period, number of HARQ processes, HARQ process number offset, and maximum number of transmissions using configuration authorization.

[0200] The second scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, and configuration authorization period.

[0201] DCI activation signaling includes, but is not limited to: resource pool index, SL transport resource indication, second PUCCH resource indication information, HARQ process number, new data indication, configuration authorization index, and cumulative sideline authorization index.

[0202] The SL transmission resource indication includes, but is not limited to, at least one of the following: time-domain resource offset, time-domain resource allocation, frequency-domain resource allocation, and starting sub-channel index.

[0203] Furthermore, the second scheduling information may also include third PUCCH resource indication information. After the base station sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal, the second terminal sends an ACK feedback to the base station on the resource indicated by the third PUCCH resource indication information. Then the base station sends an acknowledgment message to the first terminal, and after receiving the acknowledgment message, the first terminal sends the target information on the target SL transmission resource (i.e., the target configuration authorized resource) confirmed according to the first scheduling information.

[0204] Example 6

[0205] Before step 502, which determines the target SL transmission resource for each configuration authorization period based on the first scheduling information, and before sending the target information on the target SL transmission resource for each configuration authorization period, the method further includes:

[0206] Before the first SL transmission resource in each configuration authorization period, TCI status information is sent to the base station, and the TCI status information includes at least one of the following: QCL type configuration and reference signal resource indication.

[0207] Specifically, based on the above embodiments four and five, before determining the target SL transmission resource in each configuration authorization period according to the first scheduling information, the first terminal sends TCI status information to the base station in each configuration authorization period. If the base station receives the TCI status information sent by the first terminal before the first SL transmission resource in each configuration authorization period, it sends the TCI status information and / or the terminal identification information of the first terminal to the second terminal, so that the second terminal determines the target beam used to receive the target information on the target SL transmission resource in each configuration authorization period according to the TCI status information.

[0208] The TCI status information includes, but is not limited to: QCL type configuration and reference signal resource indication.

[0209] Example: As shown in Figure 3, each configuration authorization period has configuration authorization resources (i.e., SL transmission resources) R1, R2, and R3. Before the first configuration authorization resource R1 in each configuration authorization period, the first terminal sends TCI status information to the base station via PUCCH. Then, the base station sends TCI status information to the second terminal via PDCCH. For example, in the first configuration authorization period, the first terminal sends TCI status information to the base station via PUCCH1. Then, the base station sends TCI status information to the second terminal via PDCCH1.

[0210] TCI status information can be carried using other channels, and no specific restrictions are made here.

[0211] In summary, in this embodiment, the base station sends first scheduling information to the first terminal. The first terminal can learn about the target SL transmission resources allocated by the base station for sending target information based on the received first scheduling information. Then, the first terminal sends the target message on the target SL transmission resources. In addition, the first terminal also sends the beam-related TCI status information to the base station. The base station forwards the TCI status information to the second terminal so that the second terminal can determine the appropriate target beam to receive the target message based on the TCI status information, thereby improving the communication reliability between the first terminal and the second terminal.

[0212] The resource scheduling method for a direct link applied to a first terminal provided in this application embodiment can be executed by a resource scheduling device for a direct link applied to a first terminal. This application embodiment uses the execution of the direct link resource scheduling method by a direct link resource scheduling device as an example to illustrate the direct link resource scheduling device provided in this application embodiment.

[0213] As shown in Figure 6, this application embodiment also provides a resource scheduling device 600 for a direct link, applied to a first terminal, including:

[0214] The first receiving module 601 is used to receive the first scheduling information sent by the base station;

[0215] The second processing module 602 is configured to determine the target SL transmission resource based on the first scheduling information, and send the target information on the target SL transmission resource; or...

[0216] The target SL transmission resources for each configuration authorization period are determined based on the first scheduling information, and the target information is sent on the target SL transmission resources for each configuration authorization period.

[0217] Optionally, the device further includes:

[0218] The third sending module is used to send the terminal identification information of the second terminal to the base station, and to send a resource scheduling request and / or a cache status report to the base station.

[0219] Optionally, the device further includes:

[0220] The fourth sending module is used to send the terminal identification information of the second terminal and / or the configuration authorization index used by the first terminal and the second terminal for communication to the base station.

[0222] The second receiving module is used to receive the DCI activation signaling sent by the base station, the DCI activation signaling being used to activate the target SL transmission resource.

[0223] Optionally, the device further includes:

[0224] The fifth transmission module is used to send TCI status information to the base station before the first SL transmission resource. The TCI status information includes at least one of the following: QCL type configuration and reference signal resource indication.

[0225] Optionally, the device further includes:

[0226] The sixth sending module is used to send TCI status information to the base station before the first SL transmission resource in each configuration authorization period. The TCI status information includes at least one of the following: QCL type configuration and reference signal resource indication.

[0227] Optionally, the first scheduling information includes at least one of the following: resource pool index, SL transmission resource indication, first physical uplink control channel (PUCCH) resource indication information, hybrid automatic repeat request (HARQ) process number, new data indication, configuration index, cumulative sidelink grant index, configuration grant index, configuration grant period, number of HARQ processes, HARQ process number offset, maximum number of transmissions using configuration grant, and second PUCCH resource indication information;

[0228] The second PUCCH resource indication information includes at least one of the following: PUCCH resource index, physical side link feedback channel PSFCH, and the time interval between PUCCH.

[0229] In summary, in this embodiment, the base station sends first scheduling information to the first terminal. The first terminal can learn about the target SL transmission resources allocated by the base station for sending target information based on the received first scheduling information. Then, the first terminal sends the target message on the target SL transmission resources. In addition, the first terminal also sends the beam-related TCI status information to the base station. The base station forwards the TCI status information to the second terminal so that the second terminal can determine the appropriate target beam to receive the target message based on the TCI status information, thereby improving the communication reliability between the first terminal and the second terminal.

[0230] The resource scheduling device for the direct link in this embodiment can be an electronic device, such as an electronic device with an operating system, or a component in an electronic device, such as an integrated circuit or a chip. The electronic device can be a terminal, or other devices besides a terminal.

[0231] The resource scheduling device for the direct link of the first terminal provided in this application embodiment can realize the various processes implemented in the method embodiments of Figures 1, 3 and 5, and achieve the same technical effect. To avoid repetition, it will not be described again here.

[0232] As shown in Figure 7, this application embodiment also provides a resource scheduling method for a direct link, applied to a second terminal. The method specifically includes the following steps:

[0233] Step 701: Receive scheduling information sent by the base station, the scheduling information including first scheduling information and / or second scheduling information;

[0234] Step 702: Determine the target SL transmission resource according to the scheduling information, and receive the target information sent by the first terminal on the target SL transmission resource; or, determine the target SL transmission resource within each configuration authorization period according to the scheduling information, and receive the target information sent by the first terminal on the target SL transmission resource within each configuration authorization period.

[0235] It should be noted that both the first terminal and the second terminal are in Radio Resource Control (RRC) connection mode, and the first terminal and the second terminal have exchanged their respective terminal identification information. When the terminal identification information of one of them is updated, the first terminal and the second terminal need to exchange their respective terminal identification information again.

[0236] In the above embodiments of this application, the base station determines the scheduling information of the direct link SL transmission resource. The scheduling information includes first scheduling information. The base station sends the first scheduling information to the second terminal. The second terminal decodes the first scheduling information according to the terminal identification information of the first terminal, and determines the target SL transmission resource used by the first terminal to transmit the target message according to the decoded first scheduling information. The second terminal receives the target message sent by the first terminal on the target SL transmission resource.

[0237] Alternatively, the base station determines the scheduling information of the direct link SL transmission resource, the scheduling information including the first scheduling information and the second scheduling information. Then, the base station sends the first scheduling information to the first terminal and the second scheduling information to the second terminal. The second terminal decodes the second scheduling information according to the terminal identification information of the second terminal, and determines the target SL transmission resource used by the target information sent by the first terminal according to the decoded second scheduling information. The second terminal receives the target message sent by the first terminal on the target SL transmission resource.

[0238] Alternatively, the base station determines scheduling information for the direct link SL transmission resources. This scheduling information includes first scheduling information, which the base station sends to the first terminal. The first terminal then uses this first scheduling information to determine the target SL transmission resources (i.e., target configuration authorization resources) allocated by the base station for sending target information within each configuration authorization period. Upon receiving the first scheduling information, the first terminal sends the terminal identification information of the second terminal and / or the configuration authorization index used by the first terminal for communication with the second terminal to the base station. The base station determines second scheduling information based on the configuration authorization index used by the first terminal for communication with the second terminal. The base station then sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal based on the terminal identification information of the second terminal. The second terminal decodes the second scheduling information based on its own terminal identification information and determines the target SL transmission resources used by the first terminal for sending target information within each configuration authorization period based on the decoded second scheduling information. The second terminal then receives the target message sent by the first terminal on the target SL transmission resources within each configuration authorization period.

[0239] Alternatively, the base station determines the scheduling information of the direct link SL transmission resources, the scheduling information including the first scheduling information and the second scheduling information. Then, the base station sends the first scheduling information to the first terminal and the second scheduling information to the second terminal. The second terminal decodes the second scheduling information according to the terminal identification information of the second terminal, and determines the target SL transmission resources used by the target information sent by the first terminal in each configuration authorization period according to the decoded second scheduling information. The second terminal receives the target message sent by the first terminal on the target SL transmission resources in each configuration authorization period.

[0240] In summary, the first terminal acts as the transmitting terminal, and the second terminal acts as the receiving terminal. The base station sends scheduling information to the receiving terminal, thereby allowing the receiving terminal to determine the target SL transmission resource used by the transmitting terminal to transmit target information or the target SL transmission resource used by the transmitting terminal to transmit target information within each configuration authorization period. The transmitting terminal transmits target information on the target SL transmission resource or transmits target information on the target SL transmission resource within each configuration authorization period, and the receiving terminal transmits target information on the target SL transmission resource or receives target information on the target SL transmission resource within each configuration authorization period, thus ensuring the reliability of communication between the transmitting and receiving terminals.

[0241] The resource scheduling method for the above-mentioned direct link will be described in detail below through specific embodiments:

[0242] Example 1

[0243] The base station determines the scheduling information of the direct link SL transmission resources. This scheduling information includes first scheduling information. The base station then sends the first scheduling information to the second terminal. The second terminal decodes the first scheduling information based on the terminal identification information of the first terminal and determines the target SL transmission resource used by the first terminal to transmit the target message based on the decoded first scheduling information. That is, the first terminal acts as the sending terminal, and the second terminal acts as the receiving terminal. The base station sends the first scheduling information of the SL transmission resources to the receiving terminal, thereby informing the receiving terminal of the target SL transmission resource used by the sending terminal to transmit the target information. The sending terminal transmits the target information on the target SL transmission resource, and the receiving terminal receives the target information on the target SL transmission resource, ensuring the reliability of communication between the sending and receiving terminals.

[0244] It should be noted that the first scheduling information can be carried through DCI signaling.

[0245] Furthermore, the first scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, first PUCCH resource indication information, HARQ process number, new data indication, configuration index, and cumulative sideline authorization index.

[0246] The SL transmission resource indication includes, but is not limited to, at least one of the following: time-domain resource offset, time-domain resource allocation, frequency-domain resource allocation, and starting sub-channel index.

[0247] The first PUCCH resource indication information is the PUCCH resource index.

[0248] Furthermore, the first scheduling information may also include: second PUCCH resource indication information and third PUCCH resource indication information. After decoding the first scheduling information, the first terminal sends an ACK feedback to the base station on the resource indicated by the second PUCCH resource indication information. After decoding the first scheduling information, the second terminal sends an ACK feedback to the base station on the resource indicated by the third PUCCH resource indication information. Then, the base station sends an acknowledgment message to the first terminal. After receiving the acknowledgment message, the first terminal sends the target information on the target SL transmission resource confirmed according to the decoded first scheduling information.

[0249] Example 2

[0250] The base station determines the scheduling information of the direct link SL transmission resource. The scheduling information includes the first scheduling information and the second scheduling information. The base station sends the first scheduling information to the first terminal and the second scheduling information to the second terminal. The second terminal decodes the second scheduling information according to its terminal identification information and determines the target SL transmission resource used by the target information sent by the first terminal based on the decoded second scheduling information. That is, the first terminal acts as the sending terminal and the second terminal acts as the receiving terminal. The base station sends the second scheduling information to the receiving terminal, thereby the receiving terminal learns the target SL transmission resource for the sending terminal to transmit the target information through the second scheduling information. The sending terminal transmits the target information on the target SL transmission resource, and the receiving terminal receives the target information on the target SL transmission resource, ensuring the reliability of communication between the sending terminal and the receiving terminal.

[0251] It should be noted that the first and second scheduling information can be carried through DCI signaling.

[0252] Furthermore, the first scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, first PUCCH resource indication information, HARQ process number, new data indication, configuration index, and cumulative sideline authorization index.

[0256] Furthermore, the first scheduling information may also include second PUCCH resource indication information. After decoding the first scheduling information, the first terminal sends an ACK feedback to the base station on the resource indicated by the second PUCCH resource indication information.

[0257] The second scheduling information may further include: third PUCCH resource indication information. After decoding the second scheduling information, the second terminal sends an ACK feedback to the base station on the resource indicated by the third PUCCH resource indication information. Then, the base station sends an acknowledgment message to the first terminal. After receiving the acknowledgment message, the first terminal sends the target information on the target SL transmission resource confirmed according to the decoded first scheduling information.

[0258] Example 3

[0259] Before step 702, which determines the target SL transmission resource based on the scheduling information and receives the target information sent by the first terminal on the target SL transmission resource, the method further includes:

[0260] If TCI status information is received before the first SL transmission resource, the target beam used to receive the target information on the target SL transmission resource is determined based on the TCI status information.

[0261] If the TCI status information is not received before the first configured authorized resource, the target beam is determined by the previously received TCI status information or beam pairing.

[0262] The TCI status information includes at least one of the following: QCL type configuration, reference signal resource indication.

[0263] Specifically, based on Embodiments 1 and 2 above, after decoding the first scheduling information, the first terminal sends TCI status information to the base station. The base station then sends the TCI status information and / or the terminal identification information of the first terminal to the second terminal. If the second terminal receives the TCI status information before the first SL transmission resource, it determines the target beam to use for receiving the target information sent by the first terminal on the target SL transmission resource based on the TCI status information. If the second terminal does not receive the TCI status information before the first SL transmission resource, it determines the target beam using the previously received TCI status information; or if the second terminal does not receive the TCI status information before the first SL transmission resource, it determines the target beam through beam pairing.

[0264] The TCI status information includes, but is not limited to: QCL type configuration and reference signal resource indication.

[0265] Example 4

[0266] The base station determines the scheduling information for the direct link (SL) transmission resources. This scheduling information includes first scheduling information, which the base station sends to the first terminal. The first terminal then uses this first scheduling information to determine the target SL transmission resources (i.e., target configuration authorization resources) allocated by the base station for transmitting target information within each configuration authorization period. Upon receiving the first scheduling information, the first terminal sends the terminal identification information of the second terminal and the configuration authorization index used for communication between the first terminal and / or the second terminal to the base station. The base station determines second scheduling information based on the configuration authorization index used for communication between the first terminal and the second terminal. The base station then sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal based on the terminal identification information of the second terminal. The second terminal decodes the second scheduling information based on its own terminal identification information and determines the target SL transmission resources used by the first terminal for transmitting target information within each configuration authorization period based on the decoded second scheduling information. Thus, the first terminal transmits target information on the target SL transmission resources within each configuration authorization period, and the second terminal receives target information on the target SL transmission resources within each configuration authorization period, ensuring reliable communication between the first and second terminals.

[0267] The first and second scheduling information can be carried through RRC signaling.

[0268] Furthermore, the first scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, configuration authorization index, configuration authorization period, number of HARQ processes, HARQ process number offset, maximum number of transmissions using configuration authorization, and second PUCCH resource indication information;

[0269] The second PUCCH resource indication information includes, but is not limited to, at least one of the following: PUCCH resource index, the time interval between the physical side link feedback channel PSFCH and PUCCH.

[0270] The SL transmission resource indication includes, but is not limited to, at least one of the following: time-domain resource offset, time-domain resource allocation, frequency-domain resource allocation, and starting sub-channel index.

[0271] Furthermore, the second scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, and configuration authorization period.

[0272] Furthermore, the second scheduling information may also include third PUCCH resource indication information. After the base station sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal, the second terminal sends an ACK feedback to the base station on the resource indicated by the third PUCCH resource indication information. Then the base station sends an acknowledgment message to the first terminal, and after receiving the acknowledgment message, the first terminal sends the target information on the target SL transmission resource (i.e., the target configuration authorized resource) confirmed according to the first scheduling information.

[0273] Example 5

[0274] The base station determines first scheduling information and sends it to the first terminal. The first terminal then uses this information to determine the target SL transmission resources (i.e., target configuration authorization resources) allocated by the base station for transmitting target information within each configuration authorization period. After sending the first scheduling information to the first terminal, the base station sends a DCI activation signaling message to the first terminal. This DCI activation signaling message is used to activate the target SL transmission resources (i.e., target configuration authorization resources). Upon receiving the DCI activation signaling message, the first terminal sends the terminal identification information of the second terminal and / or the configuration authorization index used by the first terminal for communication with the second terminal to the base station. The base station determines second scheduling information based on the configuration authorization index used by the first terminal for communication with the second terminal. The base station then sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal based on the terminal identification information of the second terminal. The second terminal decodes the second scheduling information based on its own terminal identification information and determines the target SL transmission resources used by the first terminal for transmitting target information within each configuration authorization period based on the decoded second scheduling information. Thus, the first terminal transmits target information on the target SL transmission resources within each configuration authorization period, and the second terminal receives target information on the target SL transmission resources within each configuration authorization period, ensuring the reliability of communication between the first terminal and the second terminal.

[0275] It should be noted that the first and second scheduling information can be carried through RRC signaling.

[0276] Furthermore, the first scheduling information includes, but is not limited to, at least one of the following: resource pool index, configuration authorization index, configuration authorization period, number of HARQ processes, HARQ process number offset, and maximum number of transmissions using configuration authorization.

[0277] The second scheduling information includes, but is not limited to, at least one of the following: resource pool index, SL transmission resource indication, and configuration authorization period.

[0278] DCI activation signaling includes, but is not limited to: resource pool index, SL transport resource indication, second PUCCH resource indication information, HARQ process number, new data indication, configuration authorization index, and cumulative sideline authorization index.

[0279] The SL transmission resource indication includes, but is not limited to, at least one of the following: time-domain resource offset, time-domain resource allocation, frequency-domain resource allocation, and starting sub-channel index.

[0280] Furthermore, the second scheduling information may also include third PUCCH resource indication information. After the base station sends the second scheduling information and / or the terminal identification information of the first terminal to the second terminal, the second terminal sends an ACK feedback to the base station on the resource indicated by the third PUCCH resource indication information. Then the base station sends an acknowledgment message to the first terminal, and after receiving the acknowledgment message, the first terminal sends the target information on the target SL transmission resource (i.e., the target configuration authorized resource) confirmed according to the first scheduling information.

[0281] Example 6

[0282] Before step 702 determines the target SL transmission resource for each configuration authorization period based on the scheduling information, and before receiving the target information sent by the first terminal on the target SL transmission resource for each configuration authorization period, the method further includes:

[0283] If TCI status information is received before the first SL transmission resource in each configuration authorization period, then the target beam used to receive the target information on the target SL transmission resource in each configuration authorization period is determined based on the TCI status information.

[0284] If the TCI status information is not received before the first SL transmission resource in each configuration authorization cycle, the target beam is determined by the previously received TCI status information or beam pairing.

[0285] The TCI status information includes at least one of the following: QCL type configuration, reference signal resource indication.

[0286] Specifically, based on the above embodiments four and five, the first terminal sends TCI status information to the base station in each configuration authorization period. The base station sends the TCI status information and / or the terminal identification information of the first terminal to the second terminal. If the second terminal receives the TCI status information before the first SL transmission resource in each configuration authorization period, it determines the target beam used to receive the target information on the target SL transmission resource in each configuration authorization period according to the TCI status information, and uses the target beam to receive the target information sent by the first terminal on the target SL transmission resource in each configuration authorization period. If the second terminal has not received TCI status information before the first SL transmission resource in each configuration authorization period, the second terminal determines the target beam used to receive target information on the target SL transmission resource in each configuration authorization period based on the previously received TCI status information, and uses the target beam to receive the target information sent by the first terminal on the target SL transmission resource in each configuration authorization period; or, if the second terminal has not received TCI status information before the first SL transmission resource in each configuration authorization period, the second terminal determines the target beam used to receive target information on the target SL transmission resource in each configuration authorization period through beam pairing, and uses the target beam to receive the target information sent by the first terminal on the target SL transmission resource in each configuration authorization period.

[0287] The TCI status information includes, but is not limited to: QCL type configuration and reference signal resource indication.

[0288] Example: As shown in Figure 3, each configuration authorization period has configuration authorization resources (i.e., SL transmission resources) R1, R2, and R3. Before the first configuration authorization resource R1 in each configuration authorization period, the first terminal sends TCI status information to the base station via PUCCH. Then, the base station sends TCI status information to the second terminal via PDCCH1. For example, in the first configuration authorization period, the first terminal sends TCI status information to the base station via PUCCH, and then the base station sends TCI status information to the second terminal via PDCCH1.

[0289] If the second terminal has not received TCI status information before the configuration authorization resource R1 of each configuration authorization cycle, the target beam is determined based on the latest TCI status information received previously, or the communication beam determined by beam pairing is used as the target beam.

[0290] TCI status information can be carried using other channels, and no specific restrictions are made here.

[0291] In summary, in the embodiments described above, the base station sends scheduling information to the second terminal, thereby enabling the second terminal to obtain the target SL transmission resource for transmitting target information from the first terminal. The first terminal transmits the target information on the target SL transmission resource, and the second terminal also transmits the target information on the target SL transmission resource, ensuring the communication reliability between the sending terminal and the receiving terminal. Furthermore, the first terminal also sends beam-related TCI status information to the base station, which forwards the TCI status information to the second terminal, enabling the second terminal to determine the appropriate target beam to receive the target message based on the TCI status information, further improving the communication reliability between the first terminal and the second terminal.
