Methods to handle scheduling requests for ultra-reliable low latency communication (URLLC) in new radio (NR) systems

A user equipment (UE), comprising:

• wireless communication circuitry;
• and
• one or more processors coupled to the wireless communication circuitry, wherein the one or more processors are configured cause the UE to:
• trigger a buffer Status report (BSR), at a medium access control (MAC) entity of the UE, in response to data for a logical channel;
• trigger a scheduling request (SR), at the MAC entity of the UE, in response to the triggered BSR, if:
• the triggered BSR has not been canceled;
• the triggered BSR is a regular BSR and a logical channel SR delay timer is not running;
• and
• available uplink shared channel (UL-SCH) resources do not meet one or more logical channel prioritization (LCP) restrictions configured for the logical channel that triggered the BSR.

A method for operating a user equipment (UE), comprising:

• by the UE:
• triggering a buffer Status report (BSR), at a medium access control (MAC) entity of the UE, in response to data for a logical channel;
• triggering a scheduling request (SR), at the MAC entity of the UE, in response to the triggered BSR, if:
• the triggered BSR has not been canceled;
• the triggered BSR is a regular BSR and a logical channel SR delay timer is not running;
• and
• available uplink shared channel (UL-SCH) resources do not meet one or more logical channel prioritization (LCP) restrictions configured for the logical channel that triggered the BSR.
