Abstract: 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.

Abstract: A method and apparatus may be used in wireless communications. The apparatus may be an access point (AP), and may transmit a power save frame. The power save frame may include one or more Uplink (UL) Transmission Times (ULT)s. The apparatus may determine that a station (STA) did not transmit during its respective ULT. The AP may transmit another power save frame. The other power save frame may include a modified ULT. The modified ULT may be for a STA that did not transmit during its respective ULT. The other power save frame may include an unmodified ULT. The unmodified ULT may be for a STA that did not transmit.

Abstract: A method and apparatus may be used for supporting multiple hybrid automatic repeat request (H-ARQ) processes per transmission time interval (TTI). A transmitter and a receiver may include a plurality of H-ARQ processes. Each H-ARQ process may transmit and receive one TB per TTI. The transmitter may generate a plurality of TBs and assign each TB to a H-ARQ process. The transmitter may send control information for each TB, which may include H-ARQ information associated TBs with the TBs. The transmitter may send the TBs using the associated H-ARQ processes simultaneously per TTI. After receiving the TBs, the receiver may send feedback for each of the H-ARQ processes and associated TBs indicating successful or unsuccessful receipt of each of the TBs to the transmitter. The feedback for multiple TBs may be combined for the simultaneously transmitted H-ARQ processes, (i.e., TBs).
