Methods and devices for adaptive scheduling request procedure
A method includes triggering, by a Medium Access Control (MAC) entity of a User Equipment (UE), a first Scheduling Request (SR) procedure for a first logical channel, wherein the first logical channel is not configured with a valid Physical Uplink Control Channel (PUCCH) resource for the first SR procedure; and performing, by the MAC entity of the UE, a plurality of procedures in response to triggering the first SR procedure, wherein the procedures includes: initiating a Random Access (RA) procedure and canceling the first SR 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, the first logical channel being not configured with a valid Physical Uplink Control Channel (PUCCH) resource for the first SR procedure;
triggering, by the MAC entity, a second SR procedure for a second logical channel configured with a valid PUCCH resource for the second SR procedure; 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 cancelling the second SR procedure.
2. 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, the first logical channel being not configured with a valid Physical Uplink Control Channel (PUCCH) resource for the first SR procedure;
trigger a second SR procedure for a second logical channel configured with a valid PUCCH resource for the second SR procedure; and
in response to triggering the first SR procedure,
initiate a Random Access (RA) procedure, and
cancel the first SR procedure without cancelling the second SR procedure.
3. 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.
4. The method of claim 1 , wherein the first logical channel is not configured with the valid PUCCH resource for the first SR procedure on an active Bandwidth Part (BWP).
5. The UE of claim 2 , 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 2 , wherein the first logical channel is not configured with the valid PUCCH resource for the first SR procedure on an active Bandwidth Part (BWP).
