Abstract:
1. A method for determining a transmission resource of a Channel Quality Indicator, CQI, applicable to a Time Division Duplex system and a Half Division-Frequency Division Duplex system using a Discontinuous Reception operation, comprising: determining a position of a downlink sub-frame where monitoring of a Physical layer Downlink Control Channel is started in a Discontinuous Reception cycle; and determining a transmission resource of a CQI as one uplink sub-frame preceding the determined position or one or more uplink sub-frames following the determined position; wherein the determining the transmission resource of the CQI comprises: determining a queue in which uplink and downlink sub-frames are arranged in a predefined period after activation of a receiver of a User Equipment (UE) according to the determined position and a configured mode of downlink and uplink sub-frame configuration in a radio frame of the system; and determining the transmission resource of the CQI based upon the queue; and wherein the determining the transmission resource of the CQI based upon the queue comprises: determining whether the queue comprises an uplink sub-frame; and if so, then determining one or more of the uplink sub-frames in the queue as a transmission resource for the periodical or non-periodical transmission of the CQI; otherwise, determining one of uplink sub-frames preceding the determined position as the transmission resource for the periodical transmission of the CQI.
