Receiver and TRANSMITTER IN WIRELESS COMMUNICATION SYSTEMS WITH HIERARCHICAL PILOT STRUCTURE

摘要

A wireless terminal comprises receiver and a controller coupled to the receiver. The controller is configured to control the receiver to perform steps comprising receiving, from a base station, a time-frequency resource block comprising a first dedicated pilot signal, a second dedicated pilot signal, an allocation control channel that includes control information, a data channel that includes data. The controller is configured to control the receiver to receive, from the base station, signaling that includes information indicating a number of antenna ports of the base station, to decode the allocation control channel using the first dedicated pilot signal and to decode the data channel based on the signaled information, the control information of the decoded allocation control channel, the second dedicated pilot signal.
