receiving, by the UE, the mapping relationship from the network device;
determining, by the UE, according to the mapping relationship, an uplink scheduling request format corresponding to sidelink data needing to be sent; and
sending, by the UE, according to the uplink scheduling request format, an uplink scheduling request to the network device.
2. The method according to claim 1 , wherein the user capability information comprises at least one of:
whether the UE supports use of a short transmission time interval (TTI) based uplink scheduling request format; or
whether the UE supports use of a specific-length TTI based uplink scheduling request format.
3. The method according to claim 2 , wherein the uplink scheduling request formats in the mapping relationship are correspond to a TTI format supported by the UE.
4. The method according to claim 1 , wherein the sidelink data with different QoS attribute values have different ProSePer-Packet Priority (PPPP) values.
5. The method according to claim 1 , wherein the sidelink data with different QoS attribute values have different ProSePer-Packet Reliability (PPPR) values.
6. The method according to claim 1 , wherein the sidelink data with different QoS attribute values have different destination addresses.
7. The method according to claim 1 , wherein the different uplink scheduling request formats comprise uplink scheduling request formats based on different lengths of TTIs.
8. The method according to claim 1 , wherein in the mapping relationship, each type of sidelink data is mapped to a respective uplink scheduling request format.
9. User equipment (UE), comprising:
a memory with computer-executable instructions stored therein; and
a processor, configured to execute the computer-executable instructions so as to perform actions of a method for wireless communication, the actions comprise:
sending user capability information of the UE to a network device; wherein the user capability information is used for the network device to configure a mapping relationship from different sidelink data with different quality of service (QoS) attribute values to different uplink scheduling request formats based on different physical uplink control channel (PUCCH) formats;
receiving the mapping relationship from the network device;
determining, according to the mapping relationship, an uplink scheduling request format corresponding to sidelink data needing to be sent; and
sending, according to the uplink scheduling request format, an uplink scheduling request to the network device.
10. The UE according to claim 9 , wherein the user capability information comprises at least one of:
whether the UE supports use of a short transmission time interval (TTI) based uplink scheduling request format; or
whether the UE supports use of a specific-length TTI based uplink scheduling request format.
11. The UE according to claim 10 , wherein the uplink scheduling request formats in the mapping relationship correspond to a TTI format supported by the UE.
12. The UE according to claim 9 , wherein the sidelink data with different QoS attribute values have different ProSePer-Packet Priority (PPPP) values.
13. The UE according to claim 9 , wherein the sidelink data with different QoS attribute values have different ProSePer-Packet Reliablity (PPPR) values.
14. The UE according to claim 9 , wherein the sidelink data with different QoS attribute values have different destination addresses.
15. The UE according to claim 9 , wherein the different uplink scheduling request formats comprise uplink scheduling request formats based on different lengths of TTIs.
16. The UE according to claim 9 , wherein in the mapping relationship, each type of sidelink data is mapped to a respective uplink scheduling request format.
17. A non-transitory computer-readable storage medium with computer-executable instructions stored therein, wherein the computer-executable instructions, when executed by a processor, cause the processor to perform actions of
sending user capability information of a user equipment (UE) to a network device; wherein the user capability information is used for the network device to configure a mapping relationship from different sidelink data with different quality of service (QoS) attribute values to different uplink scheduling request formats based on different physical uplink control channel (PUCCH) formats;
receiving the mapping relationship from the network device;
determining an uplink scheduling request format corresponding to sidelink data needing to be sent according to the mapping relationship; and
sending an uplink scheduling request to the network device according to the uplink scheduling request format.
18. The non-transitory computer-readable storage medium according to claim 17 , wherein the user capability information comprises at least one of:
whether the UE supports use of a short transmission time interval (TTI) based uplink scheduling request format; or
whether the UE supports use of a specific-length TTI based uplink scheduling request format.
19. The non-transitory computer-readable storage medium according to claim 17 , wherein the sidelink data with different QoS attribute values have different ProSePer-Packet Priority (PPPP) values.
