摘要： A method and apparatus for processing multiple signals at a common frequency combined into a single radio frequency cable and subsequently recovering the signals without significant losses, distortion, or cross-talk. The method and apparatus includes processing multiple signals at a common frequency fed through a single radio frequency (RF) cable with or without one or more amplifiers and utilized for either forward or reverse link transmissions. The invention enables a single power amplifier to amplify multiple RF signals that occupy a common frequency channel and after amplification splitting these signals into amplified copies of the originals. The amplified signals may be sent to different antenna ports to illuminate different base station sectors if required. The signal splitting function is performed at the antenna masthead such that this method reduces the number of feeder cables running up the antenna tower by a factor of N, where N is the number of common frequency signals (e.g., the number of sectors) amplified by the single power amplifier. This invention enables a single power amplifier to simultaneously provide all the radio frequency signals necessary to feed a general N input phased array antenna system and form multiple antenna beams uniquely for several individual users simultaneously.

摘要： Techniques are provided to enable computation of beamforming weights for beamforming MIMO wireless communication between first and second wireless communication devices. At the first device comprising a first plurality of antennas, signals are received that are wirelessly transmitted from a different one of a second plurality of antennas of the second device during a corresponding one of a plurality of time slots. The first device computes beamforming weights from the received signals. When signals are to be transmitted from the first device to the second device, the first device applies the beamforming weights to signals to be transmitted from the first plurality of antennas of the first device to the second plurality of antennas of the second device.

摘要： A method and apparatus for selecting an antenna mapping in multiple-in/multiple-out (MIMO) enabled wireless communication networks. A candidate set of currently available antenna mappings is determined based upon measured long term channel conditions. An antenna mapping is selected from the candidate set, and the mapping is calibrated with a selected antenna mapping of a receiving wireless transmit/receive unit (WTRU). When the selected mappings are calibrated, packet data transmission begins. In an alternative embodiment, a calibration training frame (CTF) is used to calibrate multiple antenna mappings simultaneously or sequentially. Also disclosed are physical layer and medium access control layer frame formats for implementing antenna mapping selection according to the invention.

摘要： A base station apparatus switches between a communication mode for performing communication with a communication party and a calibration mode for performing a calibration process. In the calibration mode, a weight vector in accordance with a first algorithm for performing a null steering directivity control for orienting an area of drastically-lowered antenna gain in the direction of arrival of a reception signal. Furthermore, multiple transmission signals weighted by the acquired weight vector are output, and a correction value for readjusting the result of the null steering directivity control is acquired from a control PC. In the communication mode, multiple transmission signals are corrected by using the correction value acquired in a calibration mode, and the corrected signals are output.

摘要： The present invention relates to radio communications, and discloses a method and apparatus for feeding back and receiving acknowledgment (ACK) information of semi-persistent scheduling (SPS) data packets. The method for feeding back ACK information of SPS data packets includes: receiving an uplink downlink assignment index (UL DAI) from a base station (BS), where the value of the UL DAI indicates the number of downlink data packets (N); mapping ACKs/NAKs of k SPS data packets of the downlink data packets to positions from the (N−k+1)th ACK/NAK to the Nth ACK/NAK; and feeding back N ACKs/NAKs to the BS. This method can guarantee that N ACKs/NAKs are arranged correctly.
