摘要:
According to the teachings presented herein, each base station (14) in a group of base stations (14) is linked to an associated terminal (18) as a receiver-transmitter pair. These receiver-transmitter pairs reuse channelization resources, such that each terminal (18) represents a source of other-cell interference (also referred to as multi-user interference or MUI) for other terminals (18) in neighboring cells that are reusing all or some of the same channelization resources. Accordingly, the base stations (14) implement a gaming- based algorithm to mitigate MLJI for the multiple-input-multiple-output, MIMO, uplink signals received from their associated terminals (18). More particularly, each base station (14) functions as a player in a game, in which the allowed gaming action is the selection of the precoding matrix to be used for MIMO uplink transmissions to the base station (14) from an associated terminal (18).
摘要:
There is provided mechanisms for transmitting reference signals. A method is performed by a first network device. The method comprises transmitting, in a single orthogonal frequency-division multiplexing (OFDM) symbol, a composite reference signal to a second network device. The composite reference signal is a time domain concatenation of at least a first reference signal and a last reference signal. The composite reference signal has a single cyclic prefix. The cyclic prefix is determined according to a last part of the single OFDM symbol. There is also provided mechanisms for receiving such reference signals.
