US 12,004,218 B2 · Method and apparatus for intra-UE prioritization considering UL grant received in random access response

Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method includes identifying whether a medium access control (MAC) entity of the terminal is configured with a logical channel (LCH)-based prioritization, identifying whether a first uplink grant is associated with a random access, determining the first uplink grant to be a prioritized uplink grant, and transmitting an uplink signal based on the prioritized uplink grant.

Dependent claims

A method performed by a terminal in a wireless communication system, the method comprising:

identifying that a scheduling request (SR) is triggered;
in case that the SR is triggered and a medium access control (MAC) entity of the terminal is configured with a logical channel (LCH)—based prioritization, identifying whether a resource for an SR transmission associated with the triggered SR overlaps with an uplink grant received in a random access response (RAR);
in case that that the resource for the SR transmission does not overlap with the uplink grant received in the RAR:
identifying whether a counter for the SR transmission is less than a threshold, and
in case that the counter for the SR transmission is less than the threshold, transmitting the SR based on the resource for the SR transmission;
and
in case that the resource for the SR transmission overlaps with the uplink grant received in the RAR:
considering the SR transmission as a de-prioritized SR transmission,
considering the uplink grant received in the RAR as a prioritized uplink grant, and
transmitting an uplink signal based on the prioritized uplink grant.

A terminal in a wireless communication system, the terminal comprising:

a transceiver;
and
at least one processor coupled with the transceiver and configured to:
identify that a scheduling request (SR) is triggered,
in case that the SR is triggered and a medium access control (MAC) entity of the terminal is configured with a logical channel (LCH)—based prioritization, identify whether a resource for an SR transmission associated with the triggered SR overlaps with an uplink grant received in a random access response (RAR),
in case that that the resource for the SR transmission does not overlap with the uplink grant received in the RAR:
identify whether a counter for the SR transmission is less than a threshold, and
in case that the counter for the SR transmission is less than the threshold, transmit, via the transceiver, the SR based on the resource for the SR transmission, and
in case that the resource for the SR transmission overlaps with the uplink grant received in the RAR,
consider the SR transmission as a de-prioritized SR transmission,
consider the uplink grant received in the RAR as a prioritized uplink grant, and
transmit, via the transceiver, an uplink signal based on the prioritized uplink grant.
