Abstract
The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system, such as long term evolution (LTE). A method for operating a terminal in wireless communication system is provided. The method includes receiving, from a base station, system information including at least one parameter associated a paging operation, and monitoring a paging occasion (PO) that is determined based on the at least one parameter, during a discontinuous reception (DRX) operation.
Claims20
A method performed by a terminal in wireless communication system, the method comprising:
- transmitting, to a base station, a physical random access channel (PRACH) associated with a contention-based random access (CBRA) procedure, based on a PRACH format and a PRACH resource;
- receiving, from the base station, a random access response message in response to PRACH transmission, wherein the random access response message includes an uplink grant;
- identifying whether the random access procedure is initiated by beam failure recovery and whether the UE is configured to transmit beam failure recovery (BFR) media access control (MAC) control element (CE) in an uplink message;
- and
- in case that the random access procedure is identified to be initiated by beam failure recovery and the UE is identified to be configured to transmit the BFR MAC CE in the uplink message, transmitting, to the base station, the uplink message including the BFR MAC CE based on the uplink grant.

- receiving, from the terminal, an uplink message including beam failure recovery (BFR) media access control (MAC) control element (CE) based on the uplink grant in case that the random access procedure is initiated by beam failure recovery and the UE is configured to transmit the BFR MAC CE in the uplink message.
A terminal in wireless communication system, the terminal comprising:
- a transceiver;
- and
- a controller coupled to the transceiver and configured to:
- transmit, to a base station, a physical random access channel (PRACH) associated with a contention-based random access (CBRA) procedure, based on a PRACH format and a PRACH resource,
- receive, from the base station, a random access response message in response to a PRACH transmission, wherein the random access response message includes an uplink grant,
- identify whether the random access procedure is initiated by beam failure recovery and whether the UE is configured to transmit beam failure recovery (BFR) media access control (MAC) control element (CE) in an uplink message, and
- in case that the random access procedure is identified to be initiated by beam failure recovery and the UE is identified to be configured to transmit the BFR MAC CE in the uplink message, transmitting, to the base station, the uplink message including the BFR MAC CE based on the uplink grant.
