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： In an orthogonal frequency division multiple access (OFDMA) system including at least one base station and at least one wireless transmit/receive unit (WTRU), sub-carriers are allocated for data transmissions to multiple access WTRUs, where sub-carriers are allocated according to a consecutive sub-carrier allocation (CSA) type and a distributed sub-carrier allocation (DSA) type. Pilot signals with distributed pilot sub-carriers are transmitted and measured at each WTRU to obtain a channel quality metric for each pilot sub-carrier. Each WTRU sends feedback to the base station reporting channel quality based on the measured channel quality metrics. An allocation type is selected and adaptively switched according to channel variations in time and frequency domain.

摘要： Systems and methods for generating a demodulation reference signal for use by user equipment configured with multiple antennas based on a rank of an antenna or an antenna port are disclosed. A rank for a user equipment device is determined indicating the number of spatial layers or antenna ports in use, and the value of the rank is used to generate a cyclic shift offset and a cyclic shift, that can then be used to generate a demodulation reference signal to be used in timeslots within each spatial layer of an uplink transmission. Orthogonal cover codes may be used in conjunction with a determined cyclic shift to generate a demodulation reference signal.

摘要： Techniques for component carrier-specific reconfiguration are disclosed. A wireless transmit/receive unit (WTRU) is capable of transmitting or receiving via multiple component carriers. The WTRU may perform component carrier reconfiguration on a component carrier basis to add, remove or replace a component carrier. Discontinuous reception (DRX) and/or discontinuous transmission (DTX) may be performed on at least one component carrier, wherein DRX and/or DTX patterns on the component carriers may not overlap each other. A random access procedure may be performed at the target cell on one component carrier while other component carriers are inactive. The component carrier-specific reconfiguration or handover of a component carrier or a channel may be implemented in coordinated multiple point transmission (CoMP), wherein a handover of a control channel, not a traffic channel, may be performed. Alternatively, a handover of a traffic channel may be performed.

摘要： A criterion for biasing a binary decision requiring an unequal protection which utilizes a measured signal to interference ratio (SIR). The SIR may be derived from a determination of channel estimation. The SIR is compared against a threshold, the threshold being selected to bias the decision toward a not acknowledge (NACK) as opposed to an acknowledge (ACK) determination. The technique is advantageous for providing biased binary decisions for high speed downlink packets (HSDP) but may be utilized for both uplink and downlink applications.

摘要： Power control for devices having multiple transmit antennas are disclosed, including power control methods for Physical Uplink Control Channel (PUCCH) and Sounding Reference Signal (SRS) transmissions for a wireless transmit/receive unit (WTRU). The PUCCH and SRS power control methods include selecting a multiple input multiple output (MIMO) mode and changing the power of the PUCCH or SRS transmission based on the selected MIMO mode. Another power control method estimates an antenna gain imbalance (AGI) for a WTRU having at least two transmit antennas. The AGI is based on measuring a Reference Signal Received Power (RSRP) on each transmit antenna. Each transmit antenna is then scaled by an AGI scaling factor based on the estimated AGI.

摘要： A wireless transmit/receive unit (WTRU) receives a downlink subframe having multiple component carriers, each component carrier having control information encoded in a physical data control channel (PDCCH). The WTRU performs a blind decoding of control information in a first PDCCH located within a first component carrier to obtain a location of a second PDCCH located within a second component carrier, where the location of the second PDCCH is relative to a location of the first PDCCH as control channel element offset. The WTRU decodes the second PDCCH at the obtained location.
