Abstract:
1. A method for pilot multiplexing in a wireless communication system, the method comprising: determining uplink pilot channel information in a base station, the determining uplink pilot channel information including determining a number of one or more active streams to be multiplexed; transmitting the uplink pilot channel information to one or more wireless terminals to facilitate multiplexing uplink pilots by varying, for each active stream, pilot channel bandwidth and frequency location per resource block over time within a transmission time interval according to a predetermined function of the uplink pilot channel information; and receiving and demultiplexing the multiplexed uplink pilots according to the predetermined function, wherein the frequency location of the multiplexed uplink pilots for each active stream is cyclically shifted across tones of the resource block over time within the transmission time interval to form a contiguous frequency block in each resource block.
