Patent ID: 8780771

Claim:
An apparatus for wireless communication, comprising: at least one processor configured to: determine, from among a plurality of delays for cyclic delay diversity for a multiple-input multiple-output (MIMO) transmission, a subset of delays, each of the subset of delays comprising a delay for each of a plurality of ranks, each of the plurality of ranks corresponding to a different number of virtual antennas, send, by a node of a wireless network, information associated with the determined subset of delays to a user equipment (UE), receive, from the UE, a report based on an evaluation of the subset of delays over the plurality of ranks, select, at the node, a rank from among the plurality of ranks and a delay from among the plurality of delays for cyclic delay diversity for the MIMO transmission based at least in part on the report, and exchange data with the UE based on the selected rank and with cyclic delay diversity based on the selected delay; and a memory coupled to the at least one processor.
