摘要： A method and apparatus for uplink power control in multiple-input multiple-output (MIMO) includes adjusting a total uplink transmit power level with a power offset based on a number of antennas via which an uplink subframe is transmitted. The uplink power control formula may be altered to include an additional power offset term to compensate for a MIMO mode or an existing term may be adjusted to compensate for the MIMO mode.

摘要： A power control scheme for an enhanced Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (E-UTRA) physical uplink shared channel (PUSCH) is disclosed. In a first embodiment, when an uplink grant is configured for accumulation commands, the wireless transmit/receive unit (WTRU) combines the accumulation commands received in both the scheduling grant and the transmit power control physical downlink control channel. In a second embodiment, when an uplink grant is configured for absolute commands, the WTRU resets the accumulation control function immediately after receiving each absolute transmit power control command and then combines the absolute power control with the accumulation power control.

摘要： A method and system for implementing multi-user virtual multiple-input multiple-output (MIMO) techniques for wireless transmit/receive units (WTRUs) having one or more antennas are disclosed. The system includes a base station and at least one WTRU having at least two antennas. The number of antennas of the base station is not less than the number of antennas of any of the WTRUs. The base station generates a channel matrix for the WTRUs and processes received signals from the WTRUs based on a measurement of the channel matrix. The WTRUs may perform transmit precoding or eigen-beamforming using the channel matrix information. The WTRUs may also perform transmit diversity.

摘要： A combined open loop and closed loop (channel quality indicator (CQI)-based) transmit power control (TPC) scheme with interference mitigation for a long term evolution (LTE) wireless transmit/receive unit (WTRU) is disclosed. The transmit power of the WTRU is derived based on a target signal-to-interference noise ratio (SINR) and a pathloss value. The pathloss value pertains to the downlink signal from a serving evolved Node-B (eNodeB) and includes shadowing. An interference and noise value of the serving eNodeB is included in the transmit power derivation, along with an offset constant value to adjust for downlink (DL) reference signal power and actual transmit power. A weighting factor is also used based on the availability of CQI feedback.

摘要： A method and apparatus for implementing hybrid automatic repeat request (H-ARQ) in a multiple-input multiple-output (MIMO) wireless communication system are disclosed. A transmitter transmits at least two data packets via two or more antennas. If at least one of the data packets is not successfully transmitted, the transmitter retransmits the data packets while rearranging the data packets in an orthogonal spreading manner. Alternatively, the transmitter may retransmit only the unsuccessfully transmitted data packet along with a new data packet which replaces a successfully transmitted data packet. The unsuccessfully transmitted data packet may simply be repeated without changing its format. When only the unsuccessfully transmitted data packet is retransmitted along with the new data packet, the transmissions may be combined to recover the retransmitted data packet and the new data packet simultaneously.

摘要： A code division multiple access communication system transmits a pilot and traffic signal over a shared spectrum. The pilot and traffic signal have an associated code and are received over the shared spectrum. The received signals are sampled and the samples are delayed to produce a window. A weighted value for each despread pilot code window sample is determined using an adaptive algorithm. Each window sample is despread with a traffic code. Each despread traffic code window sample is weighted according to a weight corresponding to its respective pilot code sample.

摘要： A wireless communication system, method and apparatus are provided for soft and softer handover of a mobile wireless transmit/receive unit (WTRU) between two or more base stations and/or base station sectors. A network control unit assigns selected base stations to transmit communication data to the WTRU based on the WTRU being disposed in base station or base station sector geographic range of service. A joint detector (JD) receiver is configured to receive and process one or more wireless data signals in each of a series of timeframes where each signal received within a common timeslot has a unique channel encoding of the same communication data. The JD receiver has a plurality of channel estimators that estimate received signals within a common timeslot and a combiner configured to decode and combine the channel estimates to derive a resultant data signal.

摘要： A method and apparatus for measuring and reporting a rank and/or a precoding matrix for multiple-input multiple-output (MIMO) communication are disclosed. A metric indicating a channel condition is measured and a rank is selected based on the metric. The metric may be a signal-to-interference and noise ratio (SINR), throughput, a block error rate (BLER), system capacity, a sum rate, or the like. An SINR for each radio block group (RBG) for each rank is calculated. A data rate is calculated for each RBG based on the SINR for each rank. An overall rate for all RBGs is calculated for each rank. At least one rank is selected based on the overall rate. At least one precoding matrix may be selected jointly with or separately from the at least one rank.
