A system (25) and method (52) in which two base stations- a. Primary Base Station, PBS, (34) and a Secondary Base Station, SBS, (36)- -are used to accomplish a Virtual 2-antemia Receiver, V2RX, scheme, 'fhe PBS may perform the initial transmissions of symbols, but, instead of the PBS, the SBS may handle the subsequent reception of terminal -specific Channel State Information, CSI, and the broadcast of an additional signal. The SBS can be much simpler in design than the PBS, and. can be located physically closer to the terminals (28, 29), requiring less power for the feedback signals.from the terminals and also for the SBS's own broadcast of the additional signal to the terminals. The reception and usage of stale CSI using a secondary base station can be important for dense networks with a large number of simple terminals. |
