[0021] The information transmission method and terminal provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0022] like Figure 2 As shown, one embodiment of this application provides an information transmission method 200, which can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal, and the method includes the following steps.

[0023] S202: The terminal determines the priority of uplink transmission and sidelink transmission.

[0024] In this embodiment, in the case that the MAC entity of the terminal cannot perform the uplink transmission of the Uu interface and the sidelink transmission of the sidelink interface at the same time within the transmission time, the steps of S202 can be performed.

[0025] Optionally, the uplink transmission includes upper layer information, and the sidelink transmission includes physical layer information; or the uplink transmission includes physical layer information, and the sidelink transmission includes upper layer information. Of course, in other embodiments, the sidelink transmission and the uplink transmission can also be both physical layer information, or the sidelink transmission and the uplink transmission are both upper layer information.

[0026] The physical layer information of the sidelink transmission mentioned above includes at least one of the following: a sidelink synchronization signal and a physical broadcast block (S-SS / PSBCH block), a physical sidelink feedback channel (PSFCH), and a target physical channel. The target physical channel includes, for example, a physical sidelink control channel (PSCCH), a physical sidelink shared channel (PSSCH), a physical channel for transmitting a discovery signal, or other newly defined physical channels.

[0027] The upper layer information of the sidelink transmission mentioned above includes at least one of the following: data, high layer signaling, for example, including Radio Resource Control (RRC) signaling or Media Access Control-Control Element (MAC CE) signaling.

[0028] The physical layer information of the uplink transmission mentioned above includes uplink control information (UCI).

[0029] The upper layer information of the uplink transmission mentioned above includes at least one of the following: MAC CE signaling, a signaling radio bearer (SRB), a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), other uplink data or signaling.

[0030] S204: The terminal transmits the uplink transmission or the sidelink transmission according to the determined priority.

[0031] For example, when the terminal determines that the priority of the sidelink transmission is higher than the priority of the uplink transmission, the terminal transmits the sidelink transmission preferentially; or when the terminal determines that the priority of the uplink transmission is higher than the priority of the sidelink transmission, the terminal transmits the uplink transmission preferentially.

[0032] The information transmission method provided in the embodiments of the present application can determine the priority of the uplink transmission and the sidelink transmission, and transmit the uplink transmission or the sidelink transmission according to the determined priority. The embodiments of the present application can avoid the problem of disorder of the transmission order of the sidelink transmission and the uplink transmission, and improve the communication efficiency. The embodiments of the present application can make the uplink MAC CE or SRB have reasonable priority for transmission, and avoid unnecessary discard.

[0033] For the above-mentioned "avoiding the problem of disorder of the transmission order of the sidelink transmission and the uplink transmission", for example, if the sidelink transmission and the uplink transmission are compared at the physical layer, different thresholds (or thresholds) may be used in the comparison process for URLLC (Ultra-Reliable and Low-Latency Communication) and non-URLLC services. For other upper layer transmissions of non-services (such as signaling), such as uplink MAC CE / SRB, the threshold corresponding to non-URLLC services may be used, and thus when the sidelink transmission and the uplink transmission are compared in priority, the uplink MAC CE / SRB that should have priority is finally reduced in priority and cannot be transmitted. The embodiments of the present application can determine the priority of the uplink transmission and the sidelink transmission, and thus the uplink MAC CE / SRB with priority can be avoided. The problem of disorder of the transmission order of the sidelink transmission and the uplink transmission can be avoided, and the uplink MAC CE or SRB can have reasonable priority for transmission, and unnecessary discard can be avoided.

[0034] To further illustrate the information transmission method provided in the embodiments of the present application, several specific embodiments will be described below. It can be understood that the following several embodiments can also be combined to form new embodiments.

[0106] In the case that the uplink transmission is upper layer information and the sidelink transmission is physical layer information, the embodiment 100 further includes: not mapping the uplink transmission to a low-priority uplink grant.

[0107] Specifically, when the uplink transmission is not URLLC, the terminal will not map the services other than URLLC to a low-priority uplink grant, nor will it map some MAC CEs or SRBs to the low-priority uplink grant, thereby avoiding being discarded when compared with the sidelink transmission.

[0108] The embodiment does not map the uplink transmission to a low-priority uplink grant, and the method further includes: sending request information, the request information being used to request uplink grant resources used by the uplink transmission.

[0109] The method provided by the embodiment further includes: in the case that the priority index corresponding to the uplink grant for the uplink transmission is 0 or the priority index field is vacant, the physical layer of the terminal sends second indication information to the upper layer, the second indication information being used to indicate that the priority index corresponding to the uplink grant for the uplink transmission is 0 or the priority index field is vacant. For example, when the priority index corresponding to the dynamic grant or the configured grant for the uplink transmission is 0 or the priority index field is vacant, the physical layer will instruct the upper layer that the priority index corresponding to the uplink transmission of the dynamic grant or the configured grant is 0.

[0110] Optionally, the not mapping the uplink transmission to the low-priority uplink grant comprises: in a logical channel priority procedure, when a high layer selects a logical channel, the data in the logical channel with a priority index of 1 is not selected to be mapped to the low-priority uplink grant; and the uplink transmission is not mapped to the low-priority uplink grant. For example, in a logical channel priority (LCP) procedure, when a high layer selects a logical channel, the data in the logical channel with an allowedPHY-PriorityIndex of 1 is not selected to be mapped to the dynamic grant or the configured grant, and the uplink transmission of a specific type is also not mapped to the dynamic grant or the configured grant.

[0112] A MAC CE of any priority;

[0113] A MAC CE of a specific type;

[0114] A MAC CE comprising at least one MAC CE with a priority higher than that of target data, the target data being data of any logical channel except data on the UL-CCCH in the uplink transmission;

[0115] An SRB.

[0116] Embodiments five to eight are specific application embodiments.

[0117] Embodiment five

[0118] This embodiment can be a specific application embodiment of embodiment two, in which a terminal (hereinafter referred to as a UE) upper layer additionally indicates to a UE physical layer (corresponding to the first indication information mentioned above) to use a URLLC-related threshold in comparing uplink transmission (UL) and sidelink transmission (SL). This embodiment comprises the following steps:

[0119] Step 0: Optionally, a base station configures a UE with a threshold for comparing uplink transmission and sidelink transmission for UL URLLC service.

[0120] Step 1: The base station schedules the UE to perform uplink transmission through DCI, and the DCI indicates a priority index of 0 or does not carry a priority index (i.e., a non-URLLC service).

[0121] Step 2: For the scheduled uplink transmission, the physical layer of the UE indicates the priority index to the upper layer.

[0122] Step 3: MAC layer performs LCP procedure, selects logical channel according to LCP procedure and performs packet assembly. If high priority MAC CE or certain specific MAC CE is put into MAC PDU during packet assembly, MAC layer indicates when delivering MAC PDU to physical layer for transmission, the indication can be 1 bit indication or other type of indication.

[0123] Step 4: After receiving the indication from upper layer, physical layer uses sl-PriorityThresholdULURLLC threshold (corresponding to the first threshold in the foregoing) as the comparison threshold of UL / SL transmission when comparing uplink transmission and sidelink transmission. Namely:

[0124] 1. If the threshold sl-PriorityThresholdULURLLC is configured by high layer:

[0125] If the minimum priority value in SL transmission is less than the threshold sl-PriorityThresholdULURLLC, SL transmission is preferred, otherwise UL transmission is preferred.

[0126] 2. If the threshold sl-PriorityThresholdULURLLC is not configured by high layer: UL transmission is preferred.

[0127] Embodiment Six

[0128] This embodiment can be a specific application embodiment of embodiment three, and the UE upper layer additionally indicates (corresponding to the first indication information in the foregoing) to the UE physical layer to use the dedicated threshold (corresponding to the second threshold in the foregoing) configured by the base station when comparing UL / SL, and this embodiment includes the following steps:

[0129] Step 0: Optionally, the base station configures a dedicated threshold for comparing uplink transmission and sidelink transmission to the UE, and the threshold is used when UL is MAC CE or SRB.

[0130] Steps 1-3: Same as steps 1-3 of embodiment five.

[0131] Step 4: After receiving the indication from upper layer, physical layer uses the dedicated threshold in step 0 as the comparison threshold of UL / SL transmission when comparing uplink transmission and sidelink transmission. Namely:

[0132] 1. If the dedicated threshold in step 0 is configured by high layer:

[0133] If the minimum priority value in SL transmission is less than the dedicated threshold in step 0, the SL transmission is prioritized, otherwise the UL transmission is prioritized

[0134] 2. If the dedicated threshold in step 0 is not configured by the higher layer: the UL transmission is prioritized

[0135] Embodiment Seven

[0136] This embodiment can be a combined application of Embodiment Two and Embodiment Three, the UE upper layer additionally indicates to the UE physical layer to use the dedicated threshold and / or the URLLC threshold configured by the base station when comparing the UL / SL. This embodiment includes the following steps:

[0137] Step 0: The base station configures the UE with a threshold for comparing uplink transmission and sidelink transmission for URLLC traffic, and / or a dedicated threshold for comparing uplink transmission and sidelink transmission, which is used when the UL is MAC CE or SRB.

[0138] Step 1: The base station schedules the UE for uplink transmission through DCI, and the DCI indicates that the priority index is 1.

[0139] Steps 2-3: Same as steps 2-3 of Embodiment Five.

[0140] Step 4: After the physical layer receives the indication from the upper layer, when it is necessary to compare uplink transmission and sidelink transmission, it compares through the two thresholds, and the specific way is shown in Embodiment Three, way 2+way 3.

[0141] Embodiment Eight

[0142] This embodiment can be a specific application of Embodiment Four, when the uplink transmission is not URLLC, the UE will not map the URLLC traffic to this grant, nor will it map some MAC CE or SRB to this grant. This embodiment includes the following steps:

[0143] Steps 0-2: Same as steps 0-2 of Embodiment Five.

[0144] Step 3: The MAC layer performs the LCP process, selects the logical channel according to the LCP process, and performs packet assembly. At this time, if there are high-priority MAC CEs or specific MAC CEs or signaling to be sent, then this grant will be skipped.

[0145] Step 4: After the physical layer receives the indication from the upper layer, when it is necessary to compare the uplink transmission and the sidelink transmission, the sl-PriorityThresholdULURLLC threshold will be used as the comparison threshold of UL / SL transmission. That is:

[0146] 1. If the upper layer configures the threshold sl-PriorityThresholdULURLLC:
