The method comprises: if a sidelink (SL) Buffer Status Report (BSR) is triggered by an event, and if a first condition is met, executing at least one of the following: triggering a scheduling request (SR); transmitting a first uplink channel comprising the SR; packeting a BSR, wherein the BSR at least comprises the SL BSR; or performing transmission of a second uplink channel comprising the packeted BSR. ## Claims ### Claim 1 A method for information transmission, applied to a terminal device, the method comprising: when a sidelink (SL) Buffer Status Report (BSR) is triggered by an event, and when a first condition is met, performing the following: triggering a scheduling request (SR); transmitting a first uplink channel comprising the SR; wherein the first condition comprises SL data that triggers the SR meets a second preset condition, and the second preset condition comprises a priority of the SL data that triggers the SR is higher than a threshold; wherein the method further comprises: when there is a conflicting UL transmission, determining whether to transmit the first uplink channel comprising the SR based on an attribute of a logical channel that triggers the SL BSR and an attribute of the conflicting UL transmission, the attribute being determined based on an attribute of a logical channel of a data Radio Link Control Protocol Data Unit (RLC PDU) included in the conflicting UL transmission. ### Claim 2 (depends on 1) The method according to claim 1, further comprising: determining whether to transmit the first uplink channel comprising the SR based on whether there is conflicting SL data. ### Claim 3 (depends on 2) The method according to claim 2, wherein determining whether to transmit the first uplink channel comprising the SR based on whether there is conflicting SL data comprises at least one of the following: triggering transmission of the first uplink channel comprising the SR when there is no conflicting SL data; or determining, when there is conflicting SL data, whether to transmit the first uplink channel comprising the SR based on a Quality of Service (QOS) attribute corresponding to the SL data. ### Claim 4 (depends on 2) The method according to claim 2, wherein when a priority of QoS corresponding to the SL data is low, it is determined to transmit the SR, and when the priority of the QoS corresponding to the SL data is high, it is determined to transmit the SL data. ### Claim 5 (depends on 4) The method according to claim 4, wherein the low priority of the QoS indicates that the priority of the QoS is lower than a threshold. ### Claim 6 A terminal device, comprising: a processor, configured to, when a sidelink (SL) Buffer Status Report (BSR) is triggered by an event, and when a first condition is met, perform the following: triggering a scheduling request (SR); transmitting a first uplink channel comprising the SR; wherein the first condition comprises SL data that triggers the SR meets a second preset condition, and the second preset condition comprises a priority of the SL data that triggers the SR is higher than a threshold; wherein the processor is configured to: when there is a conflicting UL transmission, determine whether to transmit the first uplink channel comprising the SR based on an attribute of a logical channel that triggers the SL BSR and an attribute of the conflicting UL transmission, the attribute being determined based on an attribute of a logical channel of a data Radio Link Control Protocol Data Unit (RLC PDU) included in the conflicting UL transmission. ### Claim 7 (depends on 6) The terminal device according to claim 6, wherein the processor is configured to: determine whether to transmit the first uplink channel comprising the SR based on whether there is conflicting SL data. ### Claim 8 (depends on 7) The terminal device according to claim 7, wherein the processor is configured to perform at least one of the following: triggering transmission of the first uplink channel comprising the SR when there is no conflicting SL data; or determining, when there is conflicting SL data, whether to transmit the first uplink channel comprising the SR based on a Quality of Service (QOS) attribute corresponding to the SL data. ### Claim 9 (depends on 7) The terminal device according to claim 7, wherein the processor is configured to determine to transmit the SR when a priority of QoS corresponding to the SL data is low, and determine to transmit the SL data when the priority of the QoS corresponding to the SL data is high. ### Claim 10 (depends on 9) The terminal device according to claim 9, wherein the low priority of the QoS indicates that the priority of the QoS is lower than a threshold.
