Title:

METHOD, BASE STATION AND USER EQUIPMENT FOR RADIO COMMUNICATION IN RADIO COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2015/113484

Kind Code:

A1

Abstract:

The present disclosure relates to a method, base station and user equipment (UE) for radio communication in a radio communication system, the radio communication system comprising a base station and a UE, the UE communicating with the base station in carrier aggregation mode over a plurality of component carriers. The method comprises: the base station assigns a priority to each component carrier according to at least one of the following rules to enable the UE to select, on the overlapped uplink subframes, the component carrier having the highest priority for uplink signal transmission, the rules comprising: desired power loss of uplink signal transmission over the component carrier, burden of uplink signal transmission over the component carrier, number of uplink subframes of the component carrier, and primary/secondary attributes of the component carrier for transmission of a downlink signal corresponding to the uplink signal transmitted over the component carrier. The method, base station and UE of the present disclosure can flexibly adjust the transmission carrier of a PUCCH, and optimize transmission performance of downlink data and PUCCH.
