Abstract:
The present invention provides for an improved application of signal strength weightings in a SDMA sectorized cellular network. The improved signal strength weightings application is conducted through the improved selection of weightings from a new codebook subset or by the selection of weightings from a larger codebook subset. In a further embodiment, an antenna beam index or bit map can be used to select the best beam(s) in a SDMA sectorized cellular network. In another embodiment, a field or factor in an uplink or downlink transmission packet can designate which directional transmission beam is best suited for the transmission or when the directional transmission beam should be activated.

Claim (Index 7):
A method for operating a user equipment (UE) device, to facilitate communication with a base station, the method comprising:\n transmitting, by a transmitter of the UE device, a codeword index to the base station, wherein the codeword index identifies, for a particular number of layers, a first codebook weighting matrix from within a designated subset of a codebook, wherein the codebook includes at least six codebook weighting matrices including constant modulus codebook weighting matrices and one or more antenna selection codebook weighting matrices, wherein the one or more antenna selection codebook weighting matrices include a scaled identity matrix, wherein the scaled identity matrix is defined as: 1 2 \ue8a0 [ 1 0 0 1 ] wherein each of the codebook weighting matrices includes one or more layer-related columns, wherein each of the layer-related columns includes a plurality of complex weight values having absolute value less than or equal to one, wherein said transmitting is constrained to be from within said designated subset for all closed-loop 2TX-enabled UE devices in a first sector served by the base station;\n receiving, by a receiver of the UE device, signals from the base station, wherein the signals have been generated by a precoding operation based on a particular codebook weighting matrix from the designated subset; \n recovering, by the receiver, information from the received signals; \n receiving at a subsequent time, by the receiver of the UE device, second signals from a second base station, wherein the signals have been generated by a second precoding operation based on the scaled identity matrix of the codebook; and \n recovering, by the receiver, information from the received second signals.
