Abstract: A control channel detection method and user equipment are disclosed. The control channel detection method includes: determining, by a user equipment, a control channel search interval according to a control channel resource set and/or a control channel type; and performing control channel detection in the search interval, where the control channel resource set includes at least one physical resource block. In embodiments of the present invention, the UE can determine an E-PDCCH search interval according to the control channel resource set and/or the control channel type, thereby implementing control channel detection of the UE. In this way, a solution is provided for the scenario in which multiple control channel resource sets are configured by a network side for the UE.

Abstract: The invention concerns a method for precoding in an open loop transmission communications system, wherein the method includes precoding data at each of M REs with a precoding matrix, precoding each of DM-RSs with one column of a precoding matrix which is same as that used for precoding M data REs. The method is distinguished by using at least L≧2 different precoding matrices from a set of precoding matrices W to precode the M REs and the E allocated REs such that REs precoded with a first precoding matrix are interleaved with REs precoded with at least one additional, different precoding matrix and the number of used precoding matrices L is adapted to the transmission rank r and number N of available DM-RS. The invention further concerns a radio transmitter and a user equipment.

Abstract: In a radio communication system, a number of downlink component carriers can be aggregated for communication between a network node and a User Equipment (UE). A set of downlink component carriers is determined from the number of downlink component carriers. A downlink control channel for the UE is arranged to include information being usable for identifying at least one downlink component carrier of the set of downlink component carriers. A channel quality report is to be provided for each one of the at least one identified downlink component carrier.
