摘要： Precoding information is provided (implicitly or explicitly) to a particular user equipment UE. Closed-loop spatial coding for a control channel is selected for the particular user equipment, and at least one control channel element CCE is determined within the particular user equipment's search space of the control channel that is associated with the provided precoding information. The determined at least one CCE is spatially encoded using the provided precoding information to schedule radio resources for the particular user equipment. The UE determines a search space for a control channel, and from received radio resource control signaling determines at least one CCE within the search space that is to be encoded with closed-loop spatial coding. The UE decodes the determined at least one CCE within the search space using a closed-loop spatial decoding with precoding information associated with the at least one CCE to find radio resources scheduled for the particular UE.

摘要： A signal vector is received over a plurality of channels. A channel matrix H is determined that represents at least one of the plurality of channels. An iterative algorithm such as Lenstra-Lenstra-Lovasz is used to determining a change of basis matrix T that when multiplied with the channel matrix H converges to a matrix H*T that is more orthogonal than the channel matrix H. In one aspect the iterative algorithm is upwardly bounded in the number of iterations (e.g., 20 or 30 iterations) that it may perform for any specific channel realization to determine the change of basis matrix T. In another aspect the algorithm is initiated with a matrix derived from a previously determined change of basis matrix. Both aspects may be combined in a single method or device, or either employed separately.

摘要： The present invention relates to a method, system, apparatus, receiver module and computer program product for providing a power-efficient reception, wherein a transmission signal is initially received via at least one selected or default receiving branch. Then, it is checked whether the transmission signal has been received successfully, and at least one additional receiving branch is added to the at least one selected receiving branch for retransmission, if the transmission signal has not been received successfully. Thereby, a trade-off between savings in power consumption and reduction in network capacity can be achieved.
