摘要： An apparatus and method for transmit power savings comprising determining a rate of a previous frame; determining if a current frame is an ALWAYS-ON frame, wherein the current frame temporally succeeds the previous frame; and either ignoring every other reverse link power control (RLPC) bits received on a forward power control subchannel (F-PCSCH) or applying every RLPC bits received on the F-PCSCH. In one aspect, the apparatus and method for transmit power savings comprising using a rate determination algorithm (RDA) to determine a rate of a previous frame; detecting a pilot gating pattern at the end of the previous frame; comparing the rate of the previous frame to a threshold; determining if a current frame is an ALWAYS-ON frame; and declaring the current frame to be a 0 bps frame and puncturing the F-PCSCH to a predetermined frequency.

摘要： A power control mechanism having a number of states and suitable for a communication system in which data transmissions are not continuous (i.e., bursty in nature). In one embodiment, a power control unit includes a data processor, a state machine, and a threshold adjustment element. The data processor receives and processes an input signal to provide states of data frames received from the input signal for a particular data transmission. The state machine receives the frame states and provides a current state for the power control unit. The current state is indicative of a status of a particular communication session that includes the data transmission, and is one of a number of possible states. The threshold adjustment element receives the frame status and the current state and adjusts a power control setpoint in response thereto. The setpoint is used to control the signal quality of the input signal and is adjusted in accordance with a particular adjustment scheme selected from a number of possible adjustment schemes associated with a respective possible state.

摘要： In a disclosed embodiment, signal levels of the active sectors of an access terminal are compared with the signal level of the current serving sector of the access terminal (204). Next, a delta credit is accumulated (206). If a DRC lock bit is available, then an accumulated total credit is authorized to produce an authorized accumulated total credit (208), (210). Afterwards, a new serving sector is identified from a pool of candidate sectors based on the signal levels of the active sectors and the authorized accumulated total credits (212).

摘要： A power allocation value for power control information transmitted from a first station to a plurality of stations is determined by receiving data rate control information from the plurality of stations in a communications system. Supplemental information relating to the data rate control information is then generated, and an improved signal strength value is produced in accordance with the supplemental information. The power allocation value for the power control information transmitted from the first station to the plurality of stations is determined in accordance with the improved signal strength value.

摘要： In a high data rate communication system, a method and apparatus for improved throughput while transmitting data packets within multiple time slots. In order to avoid unnecessary retransmissions of a packet, a subscriber station sends a Stop-Repeat signal to a base station, causing the base station to cease further transmissions of the packet. In order to enable successful decoding of a packet, a subscriber station sends a Continue-Repeat signal to a base station, causing the base station to send retransmissions of the packet during time slots beyond a predetermined default number of time slots.
