A transmission scheme for a plurality of transceiver pairs in a multi-user TDD communications system wherein a transmission plan corresponds to one transmission mode, each of said transceiver pair including a first transceiver (316 1 -316 M) and a second transceiver (304 1 -304 M), each transceiver including a transmitter and a receiver, each transmitter including a transmitting port (317 1 -317 M), each of said transceiver pairs defining a downlink between the transmitter of a first transceiver and the receiver of a second transceiver and further defining an uplink between the transmitter of said second transceiver and the receiver of said first transceiver, said transmitter of said first transceiver includes a pre-precoder (315 1 -315 M) coupled with the input of a precoder and a transmitting port coupled with the output of said precoder and with said receiver of said second transceiver, each transceiver pair transmitting data over at least a portion of a data transmission frame, said data transmission frame being partitioned into a downlink transmission portion and an uplink transmission portion, said transmission scheme being characterized by comprising: a partition of at least said downlink transmission portion of said data transmission frame into a plurality of precoding intervals (208 1, 208 2), each precoding interval being associated with a respective active group of transceiver pairs, each active group of transceiver pairs including a plurality of transceiver pairs, each precoding interval terminating no earlier than the end of a respective downlink data transmission period associated with at least one of the transceiver pairs in the respective transceiver active group, wherein, a different respective precoder is associated with each said active groups, wherein, at least said transmitting ports (317 1 -317 M) of the first transceivers, which are not members of an active group, turn off, wherein each said transceiver pair transmitting a residual cancellation signal during said precoding interval if the duration of said respective precoding interval is longer than said respective downlink data transmission period and when said downlink data transmission period and said respective precoding interval do not overlap one with the other. a partition of at least said downlink transmission portion of said data transmission frame into a plurality of precoding intervals (208 1, 208 2), each precoding interval being associated with a respective active group of transceiver pairs, each active group of transceiver pairs including a plurality of transceiver pairs, each precoding interval terminating no earlier than the end of a respective downlink data transmission period associated with at least one of the transceiver pairs in the respective transceiver active group, wherein, a different respective precoder is associated with each said active groups, wherein, at least said transmitting ports (317 1 -317 M) of the first transceivers, which are not members of an active group, turn off, wherein each said transceiver pair transmitting a residual cancellation signal during said precoding interval if the duration of said respective precoding interval is longer than said respective downlink data transmission period and when said downlink data transmission period and said respective precoding interval do not overlap one with the other.
