Control method for user equipment, control method for base station, and user equipment

1. A control method for a user equipment, the control method comprising:

receiving scheduling request configuration information related to a sidelink;

selecting a scheduling request configuration for a scheduling request related to the sidelink according to at least one of a plurality of criteria based on the received scheduling request configuration information; and

performing the scheduling request related to the sidelink based on the selected scheduling request configuration,

wherein:

the scheduling request configuration information is received from a base station and comprises a scheduling request configuration identity (ID) and a specific scheduling request configuration,

the specific scheduling request configuration comprises one or more scheduling request configurations, and each scheduling request configuration comprises a maximum allowable number of times for sending the scheduling request, a time during which sending the scheduling request is prohibited, scheduling request periodicity and offset information, PUCCH resource information, and bandwidth part (BWP) related information, and

the plurality of criteria comprises:

the selected scheduling request configuration being corresponding to a scheduling request prohibit timer that is not active or running,

the selected scheduling request configuration being corresponding to valid Physical Uplink Control Channel (PUCCH) resources, and

the selected scheduling request configuration being corresponding to a logical channel priority that is equivalent to a sidelink logical channel priority.

2. A user equipment, comprising:

at least one processor; and

at least one memory coupled to the at least one processor and storing one or more instructions,

wherein the one or more instructions, when executed by the at least one processor, cause the at least one processor to perform the control method according to claim 1 .

3. The control method according to claim 1 , wherein:

the scheduling request configuration information comprises the scheduling request configuration ID, and

the scheduling request configuration ID is a scheduling request procedure configuration information ID or a scheduling request resource configuration information ID.

4. A user equipment, comprising:

at least one processor; and

at least one memory coupled to the at least one processor and storing one or more instructions,

wherein the one or more instructions, when executed by the at least one processor, cause the at least one processor to perform the control method according to claim 3 .

5. The control method according to claim 2 , wherein:

when the scheduling request configuration ID is the scheduling request procedure configuration information ID, the scheduling request configuration information further comprises the maximum allowable number of times for sending the scheduling request and the time during which sending the scheduling request is prohibited, and

when the scheduling request configuration ID is the scheduling request resource configuration information ID, the scheduling request configuration information further comprises the maximum allowable number of times for sending the scheduling request, the time during which sending the scheduling request is prohibited, the scheduling request periodicity and offset information, and the PUCCH resource information.

6. A user equipment, comprising:

at least one processor; and

at least one memory coupled to the at least one processor and storing one or more instructions,

wherein the one or more instructions, when executed by the at least one processor, cause the at least one processor to perform the control method according to claim 5 .

7. The control method according to claim 1 , wherein the scheduling request configuration information corresponds to each of a plurality of sidelink logical channel groups, or the scheduling request configuration information is provided according to each of a plurality of priorities included in a corresponding sidelink logical channel group.

8. A user equipment, comprising:

at least one processor, and

at least one memory coupled to the at least one processor and storing one or more instructions,

wherein the one or more instructions, when executed by the at least one processor, cause the at least one processor to perform the control method according to claim 7 .

9. The control method according to claim 1 , further comprising:

applying the selected scheduling request configuration, which is selected based on the scheduling request configuration information, to vehicle-to-everything (V2X) services when the V2X services exist; and

using random access to perform another scheduling request for other services in a sidelink communication mode.

10. A user equipment, comprising:

at least one processor; and

at least one memory coupled to the at least one processor and storing one or more instructions,

wherein the one or more instructions, when executed by the at least one processor, cause the at least one processor to perform the control method according to claim 9 .

11. The control method according to claim 1 , further comprising:

cancelling the scheduling request when the scheduling request is triggered, or prior to the scheduling request being triggered, if there is a pending scheduling request, wherein

selecting the scheduling request configuration comprises selecting the scheduling request configuration if there is no pending scheduling request.

12. A user equipment, comprising:

at least one processor, and

at least one memory coupled to the at least one processor and storing one or more instructions,

wherein the one or more instructions, when executed by the at least one processor, cause the at least one processor to perform the control method according to claim 11 .
