Method and apparatus for performing backoff for scheduling request in wireless communication system
First Claim
1. A method for scheduling uplink (UL) transmission in a wireless communication system, the method comprising:
- receiving, by a User Equipment (UE), a backoff parameter from a network via a radio resource control (RRC) message,wherein the backoff parameter relates to a transmission of a scheduling request (SR);
determining, by the UE, whether or not to apply the received backoff parameter before transmitting the SR to the network via a dedicated channel;
when it is determined that the received backoff parameter applies, transmitting, by the UE, the SR to the network via the dedicated channel according to the received backoff parameter; and
wherein the backoff parameter is configured for a specific logical channel.

Abstract
A method and apparatus for scheduling uplink (UL) transmission in a wireless communication system is provided. A user equipment (UE) receives a backoff parameter from a network, and determines whether or not to apply the received backoff parameter before transmitting a scheduling request (SR) to the network via a dedicated channel. Whether or not to apply the received backoff parameter is determined according to a prioritized access, and the prioritized access corresponds to one of emergency access, high priority access, control element/information in media access control (MAC), radio link control (RLC) or packet data convergence protocol (PDCP), data radio bearer (DRB) for voice/video service, signaling radio bearer (SRB) 0, SRB 1, SRB 2, multimedia telephony service (MMTEL)-voice, MMTEL-video, and voice over long-term evolution (VoLTE).

11. A user equipment (UE) in a wireless communication system, the UE comprising:
-
a transmitter and receiver; and a processor, coupled to the transmitter and receiver, that; controls the receiver to receive a backoff parameter from a network via a radio resource control (RRC) message, wherein the backoff parameter relates to a transmission of a scheduling request (SR); and determines whether or not to apply the received backoff parameter before the SR is transmitted to the network via a dedicated channel; when it is determined that the received backoff parameter applies, controlling the transmitter to transmit the SR to the network via the dedicated channel according to the received backoff parameter; and wherein the backoff parameter is configured for a specific logical channel. - View Dependent Claims (12, 13, 14, 15)
