    Abstract: A method and system for improving responsiveness in exchanging management and control frames in a wireless local area network are disclosed. An initiator sends a frame (action frame, management frame, CSI frame, control frame, or data frame) to a responder. Upon correctly receiving the frame, the responder sends a response frame to the initiator instead of directly sending an acknowledgement (ACK) packet. The responder preferably accesses the wireless medium to send the response frame in a short inter-frame spacing (SIFS). With this scheme, a long delay associated with having to contend for the wireless medium to send the response frame is avoided and therefore, the responsiveness and timeliness of the feedback mechanism is significantly enhanced. The response frame may be piggybacked on or aggregated with another packet.

    Abstract: A user equipment (UE) includes circuitry configured to receive control information on a downlink control channel from a base station. The control information indicates an allocation of an uplink channel and the control information is sent in response to the base station determining that the UE is to send an adaptive modulation and coding report. The circuitry is further configured in response to the control information to transmit a communication in the allocated uplink channel in a time interval including at least one time slot. The communication includes an adaptive modulation and coding report, and a transmission power level of the communication is derived from the control information and a pathloss measured by the UE.

    Abstract: A method for downlink power control for use in a spread spectrum time division communication system having time slots for communication, implemented in a user equipment, includes receiving data in a command per coded composite transport channel (CCTrCH) transmitted over a plurality of time slots. An interference power for each time slot of the plurality of time slots is measured and a single power command for the entire CCTrCH is transmitted in response to a signal to interference ratio of the received CCTrCH and the measured interference power measurement for each time slot. A subsequent data is received in the CCTrCH communication having a transmission power level for each downlink communication time slot set individually in response to the interference power measurement for that time slot and the single power command for the entire CCTrCH.

    Abstract: A wireless hybrid time division multiple access/code division multiple access (TDMA/CDMA) user equipment (UE) includes a signaling receiver and a data detection device in communication with the signaling receiver. The signaling receiver is configured to receive and recover signaled information of code and timeslot assignments of the UE to suport an RF communication. The data detection device is configured to recover from the signaling information an identifier of a plurality of assigned timeslots and an indication of a first and last code of a set of consecutive codes. The last code is identified by an identifier associated with the last code.
