Abstract  Abstract

The present invention relates to a method for transmitting a periodic channel quality report (CSI) and / or a sounding reference signal from a user equipment to a base station. In order to avoid duplicate decoding at the eNodeB in the transition phase, the present invention defines the deterministic behavior of the user equipment, and according to this behavior, the eNodeB determines whether the user equipment sends CSI / SRS. Can be determined. According to one embodiment, only uplink grants and / or downlink assignments received by subframe N-4 (including subframe N-4) are considered. Any uplink grants and / or downlink assignments received by the user equipment after subframe N-4 are discarded in the decision / determination. Further, in the determination / determination, a DRX related timer in subframe N-4 is also considered. In the second embodiment, the DRX MAC control element from the eNodeB, which instructs the user equipment to enter DRX (ie become inactive), is prior to subframe N-4, ie, subframe N− (4 + k). ) Considers its DRX MAC control element in decision / determination only if received by (including subframe N- (4 + k)).
