Abstract
A method and apparatus for delaying transmission of at least one of a buffer status report (BSR) and a power headroom report (PHR) in a wireless communication system. A user equipment (UE) triggers at least one of a BSR and a PHR, but delays transmission of the at least one of the BSR and the PHR to a base station if uplink (UL) transmission is not available. In this case, the UE may not trigger a scheduling request (SR).
Claims12
A method for delaying, by a user equipment (UE), transmission of at least one of a buffer status report (BSR) and a power headroom report (PHR) in a wireless communication system, the method comprising:
- triggering at least one of a BSR and a PHR;
- and
- delaying transmission of the at least one of the BSR and the PHR to a base station if an uplink (UL) transmission is not available,
- wherein the UL transmission is not available when in-device coexistence (IDC) interference occurs within the UE,
- wherein the IDC interference occurs within the UE due to an uplink transmission of the UE interfering with the triggering of the at least one of the BSR and the PHR, and
- wherein the uplink transmission of the UE is at least one of an uplink transmission through a dedicated-scheduling request (D-SR) channel during a scheduling request (SR) procedure, an uplink transmission related to a transmission of the BSR through allocated radio resources by the SR procedure, and an uplink transmission through an additional allocated radio resource by the BSR.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a radio frequency (RF) unit configured to transmit or receive a radio signal;
- and
- a processor coupled to the RF unit and configured to:
- trigger at least one of a buffer status report (BSR) and a power headroom report;
- and
- delay transmission of the at least one of the BSR and the PHR to a base station if an uplink (UL) transmission is not available,
- wherein the UL transmission is not available when in-device coexistence (IDC) interference occurs within the UE,
- wherein the IDC interference occurs within the UE due to an uplink transmission of the UE interfering with the triggering of the at least one of the BSR and the PHR, and
- wherein the uplink transmission of the UE is at least one of an uplink transmission through a dedicated-scheduling request (D-SR) channel during a scheduling request (SR) procedure, an uplink transmission related to a transmission of the BSR through allocated radio resources by the SR procedure, and an uplink transmission through an additional allocated radio resource by the BSR.
