The present invention provides a space-time-frequency encoding and decoding method and apparatus used in a wireless communication system. With the encoding method provided in the invention, transmission code words and their redundant elements are properly allocated on space-time-frequency units, so that the transmission codes and their partial redundancies can be transmitted via different antennas. Accordingly, at the receiving side, the redundant elements and the corresponding code word elements can be combined, so as to enhance the SNR and diversity gains for a part of the elements in the code words, and hence enhance the reception quality for the overall data stream.

The present invention relates to a control method for a communication network that has a transmitter with an array of transmit antennas and that has at least one receiver communicating with the transmitter. The receiver performs a channel measurement for a receive antenna of the receiver using a signal transmitted from the transmitter to the receiver. The receiver further determines channel coefficients for each of an array of transmit antennas at the transmitter from an output of the channel measurement, and then applies a linear, reversible and orthogonal transform to the channel coefficients, thus ascertaining channel component coefficients indicative of the individual weight of respective channel components in a transform domain. The receiver then selects one or more channel components in the transform domain and communicates to the transmitter a control signal indicative of one or more preferred channel components or a magnitude of one or more channel component coefficients, or both, in quantized form. The transmitter receives the control signal and constructs a beam pattern in the transform domain using the information received from the receiver.

According to one embodiment, a method includes establishing a plurality of wired connections between a base station and a plurality of geographically distributed remote transceivers. Each remote transceiver of the plurality of remote transceivers has one or more physical antenna ports. The plurality of remote transceivers are assigned to a plurality of sets where each set has one or more of the plurality of remote transceivers. One or more logical ports is assigned to each set of the plurality of sets. Each logical port of a set corresponds to at least one physical antenna port of the one or more remote transceivers of the respective set. Data traffic is sent from the base station to the endpoint using at least one wireless connection between the endpoint and at least one physical antenna port of the one or more remote transceivers of a first set of the plurality of sets.
