Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a transmission method, apparatus and terminal. Background Technology

[0002] There are two resource allocation methods for communication systems: one based on base station scheduling and the other based on terminal autonomous resource selection. For the terminal autonomous resource selection method, the terminal selects available transmission resources from a configured resource pool. Before resource selection, the terminal performs channel listening, selects a set of resources with less interference based on the channel listening results, and then randomly selects resources for transmission from this set. During resource selection, the terminal can use coordination signaling sent by another terminal. The transmission of this coordination signaling can be triggered by preset conditions or by request signaling sent by the terminal. Currently, coordination and request information can be transmitted on the Physical Sidelink Shared Channel (PSSCH). However, transmitting only coordination or request information on the PSSCH results in low transmission efficiency for the communication system. Summary of the Invention

[0047] To better understand, the relevant technologies and concepts that may be involved in the embodiments of this application are explained below.

[0048] New Radio (NR) Sidelink (SL) Resource Selection

[0049] There are two methods for allocating NR sidelink resources: one based on base station scheduling (mode 1) and the other based on UE self-selection (mode 2). For the base station-scheduled resource allocation method, the base station determines the sidelink resources used by the UE for data transmission and notifies the transmitting terminal (Transport UE, TX UE) via downlink signaling. For the UE-selected resource allocation method, the UE selects available transmission resources from a (pre)configured resource pool. Before resource selection, the UE performs channel sensing, selects a set of resources with less interference based on the sensing results, and then randomly selects resources for transmission from this set.

[0050] For mode 2, the specific working method is as follows:

[0051] 1) When the TX UE performs resource selection, the Medium Access Control (MAC) layer provides the physical layer with resource selection-related parameters. These parameters include the resource selection trigger time (e.g., slot_n), remaining packet delay budget (remaining PDB), priority, number of sub-channels, and resource reservation interval. After obtaining the resource selection-related parameters, the physical layer first determines the resource selection window. The lower boundary of the resource selection window is at time T1 after slot_n, and the upper boundary is at time T2 of slot_n. T2 is the value selected by the UE within the remaining PDB transmitted in its transport block (TB). T2 is no earlier than T1.

[0052] 2) Before resource selection, the UE needs to determine a candidate resource set. This is done by comparing the measured Reference Signal Received Power (RSRP) on the resources within the resource selection window with the corresponding RSRP threshold. If the RSRP is higher than the RSRP threshold, the resource is excluded and cannot be included in the candidate resource set. The remaining resources in the resource selection window after this exclusion process constitute the candidate resource set. The proportion of resources in the candidate resource set within the resource selection window must be no less than x%. If it is less than x%, the RSRP threshold needs to be increased in increments (e.g., 3dB) before the resource exclusion operation is repeated until at least x% of the resources can be selected.

[0053] 3) After the set of candidate resources is determined, the UE randomly selects transmission resources from the set. In addition, the UE can reserve transmission resources for subsequent transmissions during this transmission.

[0054] NR sidelink resource selection enhancement

[0055] Rel-17 NR SL enhancement WI is discussing enhancement schemes for resource allocation. The enhancement schemes are divided into scheme 1 and scheme 2.

[0056] For scheme 1, UE-A determines a resource set and sends coordination signaling to recommend this resource set to UE-B. UE-B can consider the resource set recommended by UE-A when making resource selection. The resources in the resource set can be either "preferred resource set" or "non-preferred resource set".

[0057] For coordination signaling transmission, both request-based coordination signaling and condition-based coordination signaling are supported. For request-based coordination signaling, UE-B sends a request signaling message, and UE-A triggers coordination signaling transmission upon receiving the request signaling message. For condition-based coordination signaling, UE-A triggers coordination signaling transmission when preset conditions are met.

[0058] The transmission method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0059] Please refer to Figure 2 , Figure 2 This is a flowchart of a transmission method provided in an embodiment of this application, such as... Figure 2 As shown, the transmission method includes the following steps:

[0060] Step 201: The terminal transmits target information on the PSSCH, or,

[0061] The terminal transmits target information on the PSSCH and multiplexes higher-layer data other than the target information on the PSSCH.

[0062] The number of target information items is at least one, and the target information includes at least one of the following:

[0063] Medium Access Control Element (MAC CE) carrying request information;

[0064] MAC CE carrying coordination information;

[0065] The second-stage sidelink control information (SCI) carries the request information;

[0066] The second phase of SCI carries coordination information;

[0067] Padding data used to trigger request signaling for resource selection;

[0068] Population data used to trigger coordination signaling for resource selection.

[0069] For example, the target information may include a MAC CE carrying request information, meaning the request information and the MAC CE can be multiplexed and transmitted on the Physical Side Link Shared Channel (PSSCH). Terminal A may send the MAC CE carrying the request information as request signaling to terminal B. Alternatively, the target information may include a MAC CE carrying coordination information, meaning the coordination information and the MAC CE can be multiplexed and transmitted on the PSSCH. Terminal A may send the MAC CE carrying the coordination information as coordination signaling to terminal B.

[0070] Optionally, the request or coordination information may also be carried in the second phase (2) nd In stage) SCI, in this case, 2 nd Stage SCI can be sent from terminal A to terminal B on the PSSCH as either request signaling or coordination signaling. Alternatively, the target information can be padding data including resource selection for triggering request signaling, sent from terminal A to terminal B on the PSSCH; or the target information can include padding data including resource selection for triggering coordination signaling, sent from terminal A to terminal B on the PSSCH.

[0071] It should be noted that terminal A and terminal B in this embodiment are merely illustrative examples and not specific examples. In some scenarios, terminal B can also send the aforementioned target information to terminal A. For example, terminal A can send a request signaling to terminal B, and after receiving the request signaling, terminal B sends a coordination signaling to terminal A; in another scenario, terminal B can also send a request signaling to terminal A, and after receiving the request signaling, terminal A sends a coordination signaling to terminal B.

[0072] In this embodiment, the terminal transmits target information on the PSSCH, for example, transmitting one or more target information; and the target information includes at least one of the following: a MAC CE carrying request information, a MAC CE carrying coordination information, and a 2... nd stage SCI, carrying coordination information 2 ndThe stage SCI, the padding data for resource selection used to trigger request signaling, and the padding data for resource selection used to trigger coordination signaling, enable request information or coordination information to be multiplexed with other data on the same PSSCH for transmission. This allows the PSSCH for transmitting request information (or request signaling) and coordination information (or coordination signaling) to also reuse other transmission information, thereby effectively improving the information transmission efficiency in the communication system and increasing the utilization rate of the transmission channel.

[0073] In addition, the terminal transmits at least one target information on the PSSCH and can multiplex higher-layer data other than the target information on the PSSCH. This enables the PSSCH to transmit not only target information but also other higher-layer data, effectively improving transmission efficiency.

[0074] When a terminal transmits multiple target information messages on the PSSCH, these target information messages can be the same or different. For example, one target information message might be a MAC CE message containing request information, while another target information message might be padding data used to trigger coordination signaling. Optionally, the target information messages transmitted by the terminal on the same PSSCH can be determined by protocol agreement, configuration, or pre-configuration.

[0075] It should be noted that the terminal can also transmit the aforementioned target information on the Physical Side Link Control Channel (PSCCH), achieving the same technical effect as transmission on the PSSCH. Subsequent embodiments will only specifically describe the transmission of the target information on the PSSCH; however, all schemes that can be implemented on the PSSCH in subsequent embodiments can also be implemented on the PSCCH. To avoid redundancy, the PSCCH will not be described separately.

[0076] In this embodiment of the disclosure, before transmitting the target information, the terminal may first determine whether the information to be transmitted is target information. If the information to be transmitted is target information, then the transmission of the target information is performed. Optionally, if the information transmitted by the terminal is the target information, the terminal transmits the target information on the PSSCH and does not reuse higher-layer data other than the target information on the PSSCH; that is, the terminal only transmits the target information on the PSSCH. For example, if the target information transmitted on the PSSCH includes a MAC CE carrying request information, then other higher-layer data, such as other MAC CEs, cannot be reused on the PSSCH for transmission, in order to ensure the reliability of the target information transmission.

[0077] Optionally, the terminal transmits target information on the PSSCH, including:

[0078] When the information transmitted by the terminal is the target information, and the target information is only physical layer information, the terminal transmits only the target information on the PSSCH.

[0079] It should be noted that when the target information transmitted by the terminal on the PSSCH is only physical layer information, such as request information 2 nd stage SCI, and / or, including 2 reconciliation information nd In stage SCI, the terminal only transmits the target information on the PSSCH. The terminal cannot multiplex higher-layer data (including the MAC layer and above) other than the target information onto the PSSCH, thereby ensuring that the priority of PSSCH transmission is not lower than the priority of the target information. It should be noted that physical layer data other than the target information may or may not be multiplexed onto the PSSCH.

[0080] Optionally, the priority corresponding to the target information is related to the priority corresponding to the target transport block (TB).

[0081] It should be noted that the target TB is the TB that the terminal will transmit on the preferred resource, or the TB associated with the preferred resource; and / or, the target TB is the TB that triggers the terminal to request the preferred resource.

[0082] The priority corresponding to the target TB is the priority used by another terminal when selecting a preferred resource. For example, if the terminal is terminal B, the target TB can be a TB that terminal B will transmit on the preferred resource, or a TB that triggers terminal B to request the preferred resource. In this case, the priority corresponding to the target TB is the priority used by terminal A when selecting the preferred resource.

[0083] In this embodiment of the disclosure, the priority corresponding to the target information is associated with the priority corresponding to the target TB, that is, there is an association relationship. Optionally, the association relationship includes at least one of the following:

[0084] The priority corresponding to one of the target information is associated with the priority corresponding to one of the target transport blocks;

[0085] The priority corresponding to one of the target information is associated with the priorities corresponding to at least two of the target transport blocks;

[0086] The priorities corresponding to at least two of the target information are associated with the priority corresponding to one of the target transport blocks.

[0087] For example, the priority of the target information and the priority of the target TB can have a one-to-one relationship, such as the target information having a priority of 1 and the target TB having a priority of 1. Alternatively, the priority of the target information and the priority of the target TB can have a one-to-many relationship, such as the target information having a priority of 0, target TB-1 having a priority of 1, and target TB-2 having a priority of 2; the target information can be associated with both target TB-1 and target TB-2. Or, the priority of the target information and the priority of the target TB can also have a many-to-one relationship, such as target information-1 having a priority of 0, target information-2 having a priority of 1, target information-3 having a priority of 2, and a target TB having a priority of 3; target information-1, target information-2, and target information-3 can all be associated with this target TB.

[0088] It should be noted that the priority of the target information can be the same as the priority of the target TB.

[0089] Optionally, if at least two target information items are transmitted on the PSSCH, and higher-layer data other than the target information is not multiplexed on the PSSCH, the first phase (1) of the PSSCH transmission... st The priority of stage)SCI is first priority, which is the highest priority among the at least two target information items. In other words, the highest priority among the priorities corresponding to the at least two target information items is set as 1. st Stage SCI priority.

[0090] Optionally, when multiplexing higher-layer data other than the target information onto the PSSCH, the priority of the first-stage SCI transmitted on the PSSCH is the second priority. The second priority is the highest priority among the higher-layer data other than the target information transmitted on the PSSCH, that is, setting the highest priority among the higher-layer data other than the target information transmitted on the PSSCH to the first priority. st Stage SCI priority.

[0091] It should be noted that when the target information is only physical layer information, and higher-layer data other than the target information is multiplexed on the PSSCH, the priority of the first-stage SCI of the PSSCH transmission is the second priority, that is, the highest priority among the higher-layer data other than the target information transmitted on the PSSCH. This avoids the terminal generating too much target information and carrying low-priority data, thus preventing a decrease in system transmission efficiency.

[0092] Optionally, the terminal transmits target information on the PSSCH and multiplexes higher-layer data other than the target information on the PSSCH, including any one of the following:

[0093] The terminal transmits at least one target information on the PSSCH and multiplexes higher-level data with a priority lower than or equal to the priority corresponding to the at least one target information on the PSSCH.

[0094] The terminal transmits at least one target information on the PSSCH and multiplexes higher-level data with a priority higher than or equal to the priority corresponding to the at least one target information on the PSSCH.

[0095] When the terminal transmits at least one target information on the PSSCH, and the at least one target information is higher-layer information, the higher-layer data other than the at least one target information is multiplexed on the PSSCH.

[0096] If the terminal outputs at least one target information on the PSSCH, and the target transmission end of the higher-layer data other than the at least one target information is the same as the target transmission end of the at least one target information, the higher-layer data other than the at least one target information is multiplexed on the PSSCH.

[0097] For example, the terminal only multiplexes higher-level data with a priority lower than or equal to the target information onto the PSSCH used to transmit the target information, thereby 1 st The priority in stage SCI is directly used to indicate the priority of the target information, without the need for an additional information field to indicate the priority of the target information.

[0098] Alternatively, the terminal can only multiplex higher-level data with a priority higher than or equal to the target information onto the PSSCH that transmits the target information, thus protecting the transmission of the target information and ensuring its effectiveness.

[0099] Alternatively, the terminal may multiplex higher-level data other than the target information onto the PSSCH that transmits the target information only when the target information is higher-level information, so that the higher-level data other than the target information can be demodulated by other terminals.

[0100] Alternatively, the terminal may multiplex the higher-level data other than the target information onto the PSSCH that transmits the target information only when the higher-level data other than the target information is transmitted to the same terminal (target transmission terminal) as the target information, so that the higher-level data other than the target information can be demodulated.

[0101] In this embodiment of the application, when the target information carries request information, or when the target information is used to trigger resource selection for request signaling, the method further includes:

[0102] The terminal selects a first transmission resource corresponding to the target information, and the setting of the first resource reservation interval corresponding to the resource selection of the first transmission resource includes at least one of the following:

[0103] If the coordination information cannot be multiplexed with higher-level data other than the coordination information and transmitted on the same PSSCH, the first resource reservation period is set to 0.

[0104] It is set by the Media Access Control (MAC) layer of the terminal.

[0105] Specifically, when a terminal selects the first transmission resource corresponding to a request signaling, if the coordination information cannot be multiplexed with higher-layer data other than the coordination information on the same PSSCH, the resource reservation interval corresponding to the resource selection of the first transmission resource corresponding to the request signaling is set to 0 to prevent the selection of redundant resources. Alternatively, the resource reservation interval can be determined autonomously by the terminal's MAC layer to improve the flexibility of resource usage.

[0106] Optionally, if the coordination information can be multiplexed with higher-layer data other than the coordination information and transmitted on the same PSSCH, the first resource reservation period is set by the MAC layer of the terminal.

[0107] Optionally, when the terminal determines that there is periodic TB transmission, the terminal can periodically send request signaling, such as sending a MAC CE carrying request information, or sending a second-stage SCI carrying request information, etc.

[0108] In this embodiment of the application, assuming the terminal is a first terminal, the first resource reservation period is indicated by a first-stage SCI associated with the first transmission resource corresponding to the request signaling, and the method may further include:

[0109] The first terminal transmits the first-stage SCI to the second terminal; the second terminal can determine the resource reservation period used when selecting preferred resources based on the first-stage SCI.

[0110] The resource reservation period used when selecting preferred resources is set to be the same as the first resource reservation period indicated by the SCI in the first stage.

[0111] In other words, after receiving the first-stage SCI, the second terminal can also know the first resource reservation period indicated by the first-stage SCI. Based on the first resource reservation period, the second terminal can determine the resource reservation period to be used when selecting the preferred resource. For example, the period of the preferred resource can be set to the first resource reservation period indicated by the first-stage SCI.

[0112] It should be noted that when determining the period of the preferred resource, the first resource reservation period indicated by the first stage SCI can be ignored, and the period can be determined according to the resource reservation period indicated by the second stage SCI or MAC CE.

[0113] In this embodiment of the application, when the target information carries coordination information, or when the target information is used to trigger resource selection for coordination signaling, the method further includes:

[0114] The terminal selects a second transmission resource corresponding to the target information, and the setting of the second resource reservation period corresponding to the resource selection of the second transmission resource includes at least one of the following:

[0115] If the coordination information cannot be multiplexed with higher-layer data other than the coordination information on the same PSSCH for transmission, the second resource reservation period is set to 0.

[0116] The terminal determines this autonomously;

[0117] When the terminal is the first terminal, the resource reservation period is set based on the notification from the second terminal.

[0118] Specifically, when a terminal selects the second transmission resource corresponding to coordination signaling, if the coordination information cannot be multiplexed with higher-layer data other than the coordination information on the same PSSCH, the terminal may set the second resource reservation period corresponding to the resource selection of the second transmission resource corresponding to the coordination signaling to 0. Alternatively, the terminal may independently determine the second resource reservation period corresponding to the resource selection of the second transmission resource; or it may determine it based on the resource reservation period notified by another terminal, in order to improve resource utilization efficiency and the terminal's transmission efficiency.

[0119] Optionally, assuming the terminal is a first terminal, the method may further include:

[0120] The first terminal receives the second resource reservation period from the second terminal.

[0121] In other words, when the first terminal selects the second transmission resource corresponding to the coordination signaling, it can determine the second resource reservation period corresponding to the resource selection of the second transmission resource based on the notification from the second terminal.

[0122] Optionally, the second resource reservation period notified by the second terminal to the first terminal includes at least one of the following:

[0123] The first terminal receives the second resource reservation period notified by the second terminal through a request message;

[0124] The first terminal receives the second resource reservation period notified by the second terminal via specific signaling;

[0125] When the target information carries request information, or when the target information is used to trigger resource selection for request signaling, the first terminal receives the second resource reservation period from the second terminal through the first-stage SCI notification associated with the target information.

[0126] For example, the second terminal may send target information to the first terminal. If the target information includes request information, such as a MAC CE carrying request information or a second-stage SCI carrying request information, the second terminal may notify the second resource reservation period in the request information.

[0127] Alternatively, the second terminal may notify the first terminal of the second resource reservation period through specific signaling, such as through PC5 Radio Resource Control (RRC) signaling, MAC CE signaling, etc.

[0128] Alternatively, the second terminal may notify the second resource reservation period in the first phase of the request signaling association (SCI).

[0129] Optionally, the second resource reservation period in the notification is used for at least one of the following:

[0130] Coordination signaling selects transmission resources;

[0131] The choice of preferred resource;

[0132] The selection of non-preferred resources.

[0133] Optionally, when the second resource reservation period is used to coordinate the selection of signaling transmission resources and the selection of preferred resources, one of the coordinated signaling transmission resources and the preferred resources adopts the second resource reservation period, and the resource reservation period of the other is set to 0.

[0134] In this embodiment of the application, when the terminal is a first terminal and the second resource reservation period is set based on the resource reservation period notified by the second terminal, the method further includes:

[0135] The first terminal receives the resource reselection counter value or C_resel from the second terminal.

[0136] In other words, the resource reselection counter value or C_resel of the first terminal during the resource selection process can be notified by the second terminal, or agreed upon by the protocol, configured, pre-configured, or determined independently by the first terminal.

[0137] Optionally, the terminal is a first terminal, and the method further includes:

[0138] The first terminal notifies the second terminal of the resource reselection counter value or C_resel.

[0139] For example, the resource reselection counter value or C_resel determined autonomously by the first terminal can also be notified to the second terminal.

[0140] In this embodiment of the application, when the terminal selects the second transmission resource corresponding to the coordination signaling, it can also independently determine the second resource reservation period corresponding to the resource selection of the second transmission resource, so as to improve the flexibility of resource use.

[0141] Optionally, when the coordination information and other higher-layer data are multiplexed and transmitted on the same PSSCH, the second resource reservation period corresponding to the second transmission resource is set by the MAC layer of the terminal.

[0142] In this embodiment of the application, when the target information carries coordination information, or when the target information is used to trigger resource selection for coordination signaling, the method further includes at least one of the following:

[0143] The terminal periodically triggers the transmission of the target information based on the target period;

[0144] The terminal periodically triggers the selection of the second transmission resource corresponding to the target information based on the target period.

[0145] It should be noted that the target information carries coordination information. For example, the target information may include a MAC CE carrying coordination information, or a second-stage SCI carrying coordination information, meaning the target information is transmitted as coordination signaling in the PSSCH; or the target information may include padding data for triggering resource selection of coordination signaling, and the target information is also transmitted as coordination signaling in the PSSCH. In this case, the triggering conditions for the terminal to send coordination signaling or the corresponding transmission resource selection include: the terminal periodically triggering the transmission of coordination signaling or the corresponding transmission resource selection based on the target period.

[0146] The target period is determined by at least one of the following:

[0147] The agreement stipulates;

[0148] Network-side device configuration;

[0149] Pre-configured;

[0150] If the terminal is the first terminal, the determination is based on the notification from the second terminal;

[0151] The terminal determines this autonomously.

[0152] Optionally, when the terminal is a first terminal and the target period is determined based on a notification from a second terminal, the method further includes at least one of the following:

[0153] The first terminal receives a notification sent by the second terminal through a request message, the notification being used to indicate that the resource reservation period of the request signaling is used as the target period;

[0154] The first terminal receives the target period notified by the second terminal via specific signaling;

[0155] When the target information carries request information, or when the target information is used to trigger resource selection for request signaling, the first terminal receives a notification sent by the second terminal through the first-stage SCI associated with the target information. The notification is used to indicate that the resource period of the request signaling is used as the target period.

[0156] For example, the second terminal may send target information to the first terminal. If the target information includes request information, such as a MAC CE carrying the request information or a second-stage SCI carrying the request information, the second terminal may send a notification via the request information to notify the first terminal to use the resource reservation period of the request signaling as the period during which the first terminal triggers coordination signaling resource selection, i.e., the target period. Optionally, the resource reservation period notified may be specifically used to trigger coordination signaling transmission or coordination signaling transmission resource selection; or, the resource reservation period notified may be used to trigger coordination signaling transmission or coordination signaling transmission resource selection, or may be used as a resource reservation period for preferred or non-preferred resource selection.

[0157] It should be noted that the resource reservation period mentioned in the notification is used for: a. triggering coordination signaling transmission or coordination signaling transmission resource selection, b. as a resource reservation period for preferred resource or non-preferred resource selection; wherein, the resource reservation period mentioned in the notification can only be used for either a or b, and the resource reservation period for the other is set to 0. For example, if the resource reservation period mentioned in the notification is used to trigger coordination signaling transmission resource selection, then the resource reservation period for preferred resource selection is set to 0.

[0158] Optionally, the second terminal may also notify the first terminal of the period for triggering coordination signaling transmission or coordination signaling transmission resource selection, i.e., the target period, through specific signaling, such as PC5 Radio Resource Control (RRC) signaling, MAC CE signaling, etc.

[0159] Alternatively, the second terminal may notify the target period in the first phase of the request signaling association (SCI).

[0160] Alternatively, the target period can be determined autonomously by the first terminal. In this case, the method further includes:

[0161] The first terminal notifies the second terminal of the target period.

[0162] In other words, the first terminal can also notify the second terminal of the period determined by itself for triggering coordination signaling transmission or coordination signaling transmission resource selection. The second terminal can determine the period for triggering coordination signaling transmission or coordination signaling transmission resource selection, and / or the resource reservation period for preferred resource or non-preferred resource selection based on the received notification.
