Method and apparatus for changing discontinuous reception cycle in wireless communication system

摘要

A method and apparatus for changing Discontinuous Reception (DRX) cycle in a wireless communication system is provided. A wireless device configures a short DRX cycle and a long DRX cycle. When a drx-ShortCycle timer expires, it is determined whether a drxInactivityTimer is run or not. Therefore, the wireless device uses one of the short DRX cycle and the long DRX cycle according to the determination. Discontinuous reception (DRX) cycle can be configured flexibly and a CSI report between the UE and the eNB can be complied with accurately.

1. A method for a user equipment (UE) determining a Discontinuous Reception (DRX) cycle in a wireless communication system, the method comprising:
utilizing a short DRX cycle while a DRX short cycle timer is running, the short DRX cycle shorter than a long DRX cycle; determining whether a DRX inactivity timer is running when the DRX short cycle timer expires; and transmitting data to a base station (BS) based on the short DRX cycle when it is determined that the DRX inactivity timer is running even when the DRX short cycle timer expires.
