[0037] The resource selection method provided by the embodiments of the present application will be described in detail below in combination with some embodiments and application scenarios thereof with reference to the accompanying drawings.

[0038] As shown in the embodiments of the present application, a resource selection method is provided, comprising: Figure 2

[0039] Step 201: A first terminal sends a first request signal, wherein the first request signal is used to request to obtain resource selection information of a target transmission.

[0040] The resource selection method of the embodiments of the present application is applicable to an enhancement scheme for resource allocation mode in a related protocol, in which the UE-B sends a request signaling to the UE-A, the UE-A feeds back a coordination signaling to the UE-B after receiving the request signaling, and the UE-B selects resources for TB transmission based on the coordination signaling.

[0041] At least one of the request signaling and the coordination signaling can be carried by a second-stage Sidelink Control Information (2nd-stage SCI) or a Medium Access Control Control Element (MAC CE). The coordination information can be used to indicate resources preferred by the UE-A for use by the UE-B (i.e., preferred resources), and / or to indicate resources not preferred by the UE-A for use by the UE-B (i.e., non-preferred resources).

[0042] In this step, the above-mentioned first request signal can be specifically a request signaling, and the above-mentioned target transmission can be a transmission performed for one resource selection. For example, the target transmission can be at least one TB transmission. The above-mentioned resource selection information can include at least one of the following: resource information preferred by the second terminal for use by the first terminal; and resource information not preferred by the second terminal for use by the first terminal.

[0043] Step 202: The first terminal obtains a first coordination signal associated with the first request signal, wherein the first coordination signal carries the resource selection information of the target transmission.

[0044] ​In the embodiments of the present application, the first terminal can receive multiple first coordination signaling. Here, the first coordination signaling associated with the first request signaling can be acquired in an implicit manner (e.g., predetermined by protocol) or an explicit manner (e.g., indicated by indication information), and then subsequent resource selection for the target transmission can be performed based on resource selection information carried by the first coordination signaling.

[0045] Step 203: The first terminal performs resource selection according to the resource selection information of the target transmission indicated by the first coordination signaling.

[0046] In the embodiments of the present application, the first terminal sends the first request signaling, acquires the first coordination signaling associated with the first request signaling, and performs resource selection based on the resource selection information of the target transmission indicated by the first coordination signaling. Since the first coordination signaling is the coordination signaling corresponding to the first request signaling, i.e., the resource selection information carried by the first coordination signaling is the resource selection information for the target transmission indicated by the first request signaling, the appropriate resource for the target transmission can be accurately selected based on the first coordination signaling.

[0047] Optionally, the first terminal acquires the first coordination signaling associated with the first request signaling, including:

[0048] The first terminal acquires the first coordination signaling associated with the first request signaling according to target information carried by at least one coordination signaling.

[0049] The target information is used to indicate at least one of the following:

[0050] Transmission resource information of the request signaling;

[0051] Control information associated with the request signaling;

[0052] Target identification.

[0053] In the specific embodiments of the present application, the transmission resource information includes at least one of time domain resource and frequency domain resource. When the target information indicates the transmission resource information of the request signaling, it can indicate index information of the time domain resource and / or the frequency domain resource, for example, slot index of the request signaling, or starting (Physical Resource Block, PRB) index of the request signaling.

[0054] The control information includes transmission parameters or HARQ related parameters (e.g., HARQ process ID, etc.).

[0055] The target identifier can be at least one of a request ID, a coordination ID, and a logical channel ID. For example, the target identifier is a logical channel ID.

[0056] The target information can be indicated by a 2nd-stage SCI.

[0057] Optionally, the first terminal obtains the first coordination signal associated with the first request signal according to target information carried in the at least one coordination signal, including:

[0058] In the target information carried in the at least one coordination signal, the first target information associated with the first request signal is determined, and the target information includes at least one of the transmission resource information and the control information.

[0059] The coordination signal carrying the first target information is taken as the first coordination signal associated with the first request signal.

[0060] In an embodiment of the present application, the target information is used to indicate the transmission resource information of the request signal and / or the control information associated with the request signal. Then, the first terminal obtains the first target information associated with the first request signal according to the target information. That is, the transmission resource information indicated by the first target information is the transmission resource information of the first request signal, or the control information indicated by the first target information is the control information associated with the first request signal. The coordination signal carrying the first target information is taken as the first coordination signal. This is an explicit indication of the first coordination signal associated with the first request signal.

[0061] Optionally, the first terminal obtains the first coordination signal associated with the first request signal according to target information carried in the at least one coordination signal, including:

[0062] The coordination signal carrying the same target identifier as the first request signal is taken as the first coordination signal.

[0063] Here, the target information is used to indicate the target identifier carried by the coordination signal. In this way, the first coordination signal associated with the first request signal is indicated by the target information indicating the target identifier, which is an explicit indication.

[0064] Optionally, the first terminal obtains the first coordination signal associated with the first request signal, including:

[0065] The coordination signal received in the target time period is taken as the first coordination signal associated with the first request signal.

[0066] The target time period refers to a time period between the first time and the second time.

[0067] The first time is the sending time of the first request signal, and the second time is T1+ a preset time interval, T1 being associated with the sending time of the first request signal.

[0068] For example, T1 is the time of the first transmission of the first request signal, or the time of the nth transmission of the first request signal, or the time of the last transmission of the first request signal, or the time when the Physical SideLink Shared Channel (PSSCH) associated with the Physical SideLink Feedback Channel (PSFCH) of the request signal transmission is located; the preset time interval is predetermined by the protocol, or (pre)configured, or indicated by the first terminal. The preset time interval can be determined according to the Packet Delay Budget (PDB). The preset time interval can be the Packet Delay Budget (PDB) used when the second terminal selects the first cooperative signal transmission resource, the second terminal receives the first request signal, and feeds back the first cooperative signal to the first terminal according to the first request signal.

[0069] In the embodiments of the present application, the second time is set to ensure that the cooperative signal received by the first terminal in the target time period is the first cooperative signal. In this way, only one cooperative signal is received in the target time period. This is an implicit indication of the first cooperative signal.

[0070] Optionally, after the first terminal sends the first request signal, the method further comprises:

[0071] The first terminal sends a second request signal, and the sending time of the second request signal is after the second time, or the sending time of the second request signal is after the receiving time of the first cooperative signal.

[0072] The first request signal can be specifically the next request signal sent after the first terminal sends the first request signal.

[0073] In the embodiments of the present application, the first terminal can send a new request signal after receiving the previous cooperation signal or after the transmission of the previous cooperation signal exceeds a preset packet delay budget (PDB), so that the request signal and the cooperation signal always have a one-to-one correspondence. This is also an implicit determination of the first cooperation signal. The typical value of the delay budget is equivalent to the delay budget used by the second terminal when selecting the transmission resource of the first cooperation signal.

[0074] Optionally, the first terminal acquires the first cooperation signal associated with the first request signal, comprising:

[0075] According to the association relationship between the first resource number of the cooperation signal and the second resource number of the request signal, the target first resource number associated with the target second resource number of the first request signal is acquired;

[0076] The cooperation signal corresponding to the target first resource number is taken as the first cooperation signal associated with the first request signal.

[0077] For example, when the first terminal receives multiple cooperation signals, the cooperation signal with a smaller resource number (time domain resource number or frequency domain resource number) is associated with the request signal with a smaller resource number (time domain resource number or frequency domain resource number). This is also an implicit determination of the first cooperation signal.

[0078] Optionally, the first terminal acquires the first cooperation signal associated with the first request signal, comprising:

[0079] The cooperation signal meeting the preset condition is taken as the first cooperation signal associated with the first request signal;

[0080] The preset condition includes at least one of the following:

[0081] The reception delay is less than or equal to a preset reception delay, for example, the cooperation signal received within the preset reception delay is the first cooperation signal;

[0082] The selection resource corresponding to the resource selection information carried meets the requirement indicated by the first terminal (the first request signal), for example, the sub-channel size meets the requirement indicated by the first request signal, the time domain position meets the requirement indicated by the first request signal;

[0083] The first request signal is transmitted in the same resource pool or carrier;

[0084] The first request signal takes effect in the same resource pool or carrier.

[0085] The above manner of taking the cooperation signal satisfying the preset condition as the first cooperation signal associated with the first request signal belongs to a manner of implicitly determining the first cooperation signal.

[0086] Optionally, in the embodiments of the present application, the request signal and / or the cooperation signal carries at least one of the following:

[0087] resource pool information;

[0088] carrier information.

[0089] In the embodiments of the present application, the first terminal sends a first request signal, acquires a first cooperation signal associated with the first request signal, and performs resource selection based on resource selection information of a target transmission indicated by the first cooperation signal. Since the first cooperation signal is the cooperation signal corresponding to the first request signal, that is, the resource selection information carried by the first cooperation signal is the resource selection information for the target transmission indicated by the first request signal, the first terminal can accurately select appropriate resources for the target transmission based on the first cooperation signal.

[0090] As shown in Figure 3 The embodiments of the present application also provide a resource selection method, which comprises:

[0091] Step 301: A second terminal receives a request signal sent by at least one first terminal, and each request signal is used for requesting to acquire resource selection information of a target transmission.

[0092] Step 302: The second terminal sends at least one cooperation signal according to the at least one request signal, wherein the cooperation signal carries target information and resource selection information of the target transmission, and the target information is used for indicating an association relationship between the cooperation signal and the request signal.

[0093] The request signal and the cooperation signal have been described in detail in the method embodiments on the first terminal side, and will not be described here again.

[0094] In the embodiments of the present application, the second terminal sends a cooperation signal according to at least one request signal, and the cooperation signal carries target information used for indicating an association relationship between the cooperation signal and the request signal and resource selection information of the target transmission. In this way, the first terminal can select a first cooperation signal associated with a first request signal sent by the first terminal through the target information, and perform resource selection based on the resource selection information carried by the first cooperation signal, thereby ensuring that the first terminal can accurately select appropriate resources for the target transmission.

[0095] Optionally, the target information comprises at least one of the following:

[0096] transmission resource information of the request signal;

[0097] control information associated with the request signal;

[0098] target identity.

[0099] The target information has been described in the above-mentioned method embodiment at the first terminal side, and will not be described here again.

[0100] Optionally, before the second terminal sends the at least one cooperation signal, the method further comprises:

[0101] determining position information of a first resource selection window, the position information comprising at least one of a first time point associated with a start position and a second time point associated with an end position, the first resource selection window being used for selecting a transmission resource for sending the cooperation signal.

[0102] In the embodiments of the present application, the first resource selection window described above can also be described as a resource selection window of the cooperation signal.

[0103] Optionally, the first time point comprises at least one of:

[0104] a time point corresponding to the start position of the first resource selection window;

[0105] an earliest time point corresponding to the start position of the first resource selection window, wherein the start position of the first resource selection window corresponds to multiple time points, and the earliest time point is selected as the first time point.

[0106] a time point at which the MAC layer of the first terminal triggers resource selection (which can be equivalent to the position of slot n in a related protocol such as 38.214);

[0107] an earliest time point at which the MAC layer of the first terminal triggers resource selection, wherein the time point at which the MAC layer triggers resource selection corresponds to multiple time points, and the earliest time point is selected as the first time point.

[0108] Optionally, the type of the first time point (the above-mentioned four types correspond to four types) can be determined based on a manner in which the second terminal acquires the request signal, and the manner in which the second terminal acquires the request signal comprises at least one of acquiring through demodulating 2nd SCI and / or acquiring through demodulating a MAC CE. In this way, more flexibility is provided for the MAC layer to determine the resource selection window.

[0109] For example, if the second terminal acquires the request signal by demodulating the 2nd SCI, the physical layer (PHY layer) directly determines the starting position of the first resource selection window; if the second terminal acquires the request signal by demodulating the MAC CE, the MAC layer determines the earliest time of slot n, the MAC layer autonomously determines the time of slot n and notifies the PHY layer, and the PHY layer determines the starting position of the first resource selection window according to slot n.

[0110] Optionally, the first time is determined according to at least one of the following:

[0111] The first item: the transmission time of the request signal, for example, the time after x time units of the request signal transmission time is the first time, x time units are determined based on the decoding process time of the request signal of the second terminal or based on the preset decoding process time of the request signal, and / or the x time units are based on the preparation time of resource selection (resource selection preparation time);

[0112] The second item: the first starting time indicated by the request signal.

[0113] For example, the latest or earliest time in the above-mentioned first item and second item can be determined as the first time.

[0114] The first starting time here can be specifically the specific starting time of the resource selection indication of the request signal as the cooperation signal, or the unified starting time of the resource selection indication of the cooperation signal and the preferred resource.

[0115] Optionally, a fixed code point is set in the first starting time, which is used to indicate that the transmission time of the request signal is the first time.

[0116] The determination mode of the above-mentioned first time is associated with the type of the above-mentioned first time.

[0117] Optionally, the second time includes at least one of the following:

[0118] The first item: the time corresponding to the end position of the first resource selection window;

[0119] The second item: the latest time corresponding to the end position of the first resource selection window (equivalent to the position of slot n+remaining PDB in the related protocol such as 38.214), here, the end position of the first resource selection window corresponds to multiple times, and the latest time is selected as the above-mentioned second time.

[0120] The third item: a target time after the time when the resource reselection is triggered;

[0121] The fourth item: a maximum value of the target time after the time when the resource reselection is triggered;

[0122] The target time is a time corresponding to a time after n time units of the time when the resource selection is triggered at the MAC layer, and the n time units are determined according to the length of the remaining PDB, for example, the maximum value of the target time is determined according to the upper limit value of the remaining PDB.

[0123] Optionally, the type of the second time (the four types correspond to the four items) is determined based on the way in which the second terminal acquires the request signal, and the way in which the second terminal acquires the request signal at least includes acquiring through demodulating the 2nd SCI and / or acquiring through demodulating the MAC CE.

[0124] Optionally, the second time is determined according to at least one of the following:

[0125] The first item: the transmission time of the request signal, for example, the time after y time units of the transmission time of the request signal is the second time, and the y time units are determined based on at least one of the following: the request signaling decoding processing time of the second terminal, the determination based on the preset request signaling decoding processing time, the determination based on the resource selection preparation time, the length of the first resource selection window, and the delay requirement of the cooperation signal feedback; the delay requirement is agreed by the protocol, or is (pre)configured, or is determined based on the rules agreed by the protocol, or is indicated by the first terminal;

[0126] The second item: the first start time or the first end time indicated by the request signal, and the first end time is the end time of the resource selection indication of the request signal as the cooperation signal and / or the preferred resource; optionally, a fixed code point is set in the first end time, which is used to indicate that the first end time is the second time. For example, the time after y2 time units of the first start time is the second time, and the y2 time units are determined based on at least one of the following: the length of the cooperation signal resource selection window, and the delay requirement of the cooperation signal feedback.

[0127] The third item is a position of a selected resource corresponding to the resource selection information, for example, a second time point is determined based on a position of a preferred resource, for example, a time point of a first time unit before a time point at which the first preferred resource is located is the second time point, the first time unit is determined based on a cooperative signal decoding time of the first terminal or a preset cooperative signal decoding time, for example, a time point of a second resource selection window corresponding to a start position of the second resource selection window is the second time point.

[0128] The fourth item is a start position of a second resource selection window of a selected resource corresponding to the resource selection information.
