摘要： The present invention is related to a method and apparatus for reducing antenna correlation between multiple antennas. A transmitter generates at least two beams with a plurality of antennas. The generated beams are spatially separated to point away each other. Therefore, the transmitted signals travel through different channel conditions and arrive at a receiver mutually uncorrelated. The beams may be generated by antennas having different antenna pattern, or by an array antenna. The beams may be polarized differently. The schemes may be implemented on a subcarrier basis in an orthogonal frequency division multiplexing (OFDM) system. Trellis coded mapping may be utilized for adjacent symbols to be mapped to antennas with low correlation.

摘要： A method and apparatus for radio resources control in a multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) communication system are disclosed. Channel metric is calculated for each of a plurality of transmit antennas. Sub-carriers are allocated to each transmit antenna in accordance with the channel metric of each transmit antenna. Signals are transmitted using the allocated sub-carriers at each antenna. Adaptive modulation and coding and transmit power control of each sub-carrier may be further implemented in accordance with the channel metric. Power control may be implemented per antenna basis or per sub-carrier basis. In performing power control, a subset of transmit antennas may be selected and waterpouring may be applied only to the selected antennas. Waterpouring may be based on SNR instead of channel response.

摘要： Splitting data in a wireless communications network. Data may be split to use multiple base stations for transmission to user equipment in order to improve the bandwith if a UE is on a cell edge, or may be split by user equipment for transmission to multiple base stations in order to improve handover. Data splitting may be performed at the Packet Data Convergence Protocol layer, at the Radio Link Control layer, or at the Media Access Control layer on user equipment or on a base station. Data may instead be split in a network node, such as in a serving gateway, in order to reduce X2 interface load or delay carrier aggregation.

摘要： Techniques for inter-cell interference cancellation are disclosed. At each transmitter, the data (message) may split into two or more layers, (e.g., common and private parts), and may be encoded in different rates, allocated with different powers, possibly beamformed using different precoders, and transmitted through the same physical channels. The common part is to be decoded at both the intended and unintended users, while the private part is to be decoded at the intended user.

摘要： A method and apparatus for correcting symbols of a common pilot channel (CPICH) to generate an accurate signal-to-interference ratio (SIR) estimate in a wireless communication system are disclosed. In one embodiment, a non-stationary mean of a group of the CPICH symbols is estimated, the CPICH symbols are delayed, and the CPICH symbols are corrected by dividing the delayed CPICH symbols by the estimated non-stationary mean of the group of CPICH symbols. In another embodiment, a signal power estimate is generated based on the magnitude of CPICH symbols, a noise power estimate is generated by subtracting the signal power estimate from a total power estimate based on the magnitude of the CPICH symbols, and a SIR estimate is generated for symbols that have undergone a time varying gain by dividing the signal power estimate by the noise power estimate.

摘要： A method and apparatus for signaling information indicating performance requirements that a WTRU commits to satisfying from the WTRU to permit a more efficient allocation of radio resources and increase network capacity. The WTRU may signal information to the base station that includes performance requirements that the WTRU commits to satisfying, that includes a code or a field associated with at least one performance requirement. In another embodiment, the signaled information indicates a change in performance requirements committed to by the WTRU. In yet another embodiment, the WTRU signals channel quality measurements, such as channel quality indicator (CQI) report messages, to the base station, which in turn infers certain information regarding receiver performance based on the channel quality measurements.

摘要： A wireless communication apparatus which uses fast Fourier transforms (FFTs) in an orthogonal frequency division multiplexing (OFDM) receiver which incorporates a beam space antenna array. The beam space antenna array may be implemented with a Butler matrix array. The beam space antenna array may be a circular array, vertical array, or a combination of both circular and vertical arrays, for providing the desired angular antenna coverage. In one embodiment, the antenna array is optimized because the FFTs are linear invariant transform operators, whereby the order of operations in the OFDM receiver can be interchanged.

摘要： A method and apparatus for providing fast detection of a high speed shared control channel (HS-SCCH). The HS-SCCH carries information necessary for receiving data via a high speed downlink shared channel (HS-DSCH). The apparatus receives messages transmitted via a plurality of HS-SCCHs. The apparatus measures a channel quality for the messages received via each HS-SCCH. The apparatus performs a threshold test by comparing the channel quality with a predetermined threshold. The apparatus then selects a HS-SCCH having the best channel quality among the HS-SCCHs.
