UPLINK PILOT MULTIPLEXING IN SINGLE USER MIMO AND SDMA FOR SINGLE CARRIER FREQUENCY DIVISION MULTIPLE ACCESS SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a system and a method that facilitate an adaptive uplink pilot multiplexing scheme.

SOLUTION: A frequency position and a pilot channel bandwidth can be adaptively varied in a block over time on the basis of uplink channel data such as the number of streams to be multiplexed. Thus, the provided adaptive uplink pilot multiplexing scheme adaptively determines a flexible uplink pilot allocation scheme while maintaining a single carrier waveform for improved transmit power efficiency of pilots and orthogonality of pilots within blocks for improved channel estimation and suppression of interference.
