Methods and devices for adaptive scheduling request procedure

1. A method performed by a User Equipment (UE), the method comprising:

triggering, by a Medium Access Control (MAC) entity, a first Scheduling Request (SR) procedure for a first logical channel;

triggering, by the MAC entity, a second SR procedure for a second logical channel; and

in response to triggering the first SR procedure,

initiating, by the MAC entity, a Random Access (RA) procedure, and

canceling, by the MAC entity, the first SR procedure without canceling the second SR procedure.

2. The method of claim 1 , wherein the first logical channel is not mapped to any SR configuration received by the UE from a base station through a downlink Radio Resource Control (RRC) message.

3. The method of claim 1 , wherein the first logical channel is not configured with a valid Physical Uplink Control Channel (PUCCH) resource for the first SR procedure on an active Bandwidth Part (BWP).

4. A User Equipment (UE) comprising:

one or more non-transitory computer-readable media having computer-executable instructions embodied thereon; and

at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to:

trigger a first Scheduling Request (SR) procedure for a first logical channel;

trigger a second SR procedure for a second logical channel; and

in response to triggering the first SR procedure,

initiate a Random Access (RA) procedure, and

cancel the first SR procedure without canceling the second SR procedure.

5. The UE of claim 4 , wherein the first logical channel is not mapped to any SR configuration received by the UE from a base station through a downlink Radio Resource Control (RRC) message.

6. The UE of claim 4 , wherein the first logical channel is not configured with a valid Physical Uplink Control Channel (PUCCH) resource for the first SR procedure on an active Bandwidth Part (BWP).
