摘要： A system and method for MIMO communications is provided. A method includes receiving a data block of P matrices from a transmitter, and determining if operating conditions are met. The method also includes if operating conditions are not met, computing a test position, selecting a codeword based on the test position, and computing a metric. The metric may then be compared with an error radius to determine a validity of the codeword. If the codeword is invalid, another codeword is selected. If the codeword is valid, then the codeword is stored if all matrices have been evaluated, else another matrix is selected for evaluation. If matrices earlier in the data block have untested codewords while all codewords for a matrix being evaluated have been tested, backtracking may be performed. After the codewords for the data block have been found, the stored data may be outputted and processed.

摘要： A system and method for enabling coordinated beam switching and scheduling in a wireless communications system. A method for controller operation includes indicating that the controller is operating in a cooperative beam switching mode, transmitting a beam formed reference signal (BFRS), from each communications device being served by the controller, receiving a measurement of a communications channel between the controller and the communications device and an indicator indicating a transmission unit corresponding to the measurement of the communications channel, receiving a transmission intended for a communications device, and causing the transmission to be transmitted to the communications device.

摘要： A base station for communicating with mobile stations in a coverage area of a wireless network. The base station comprises a first transmit antenna, a second transmit antenna, and an RF transceiver for generating an outgoing RF signal to be transmitted via the first and second transmit antennas to the mobile stations. The base station also comprises a switch coupling the RF transceiver to the first and second transmit antennas. The switch alternately directs the outgoing RF signal to the first transmit antenna during a first portion of a forward channel data frame and directs the outgoing RF signal to the second transmit antenna during a remaining portion of the forward channel data frame.
