Title:
METHOD AND APPARATUS FOR CONTROLLING UPLINK TRANSMISSION ON DISCONTINUOUS RECEPTION OPERATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/010903
Kind Code:
A1
Abstract:
A method and apparatus for controlling uplink transmissions on Discontinuous reception (DRX) operation are provided. A wireless device chooses that a Channel Quality Indicator (CQI)/ Precoding Matrix Index (PMI)/Rank Indicator(RI)/ Precoding Type Indicator (PTI) on a Physical Uplink Control Channel (PUCCH) are not reported at a subframe n if an onDurationTimer is determined to be not active at the sub-frame n. An uncertainty about the uplink control information during the On Duration occurred by previous DRX operation can be resolved.
