Abstract: An access terminal (206) configured for wireless communication with an acces s network (204) within a sector (1032). The access terminal (206) includes a transmitter (2608) for transmitting a reverse traffic channel to the access network (204), an antenna (2614) for receiving signals from the access netwo rk (204), a processor (2602) and memory (2604) in electronic communication with the processor (2602). Instructions stored in the memory (2604) implement a method of determining whether a current power allocation grant (1374) for a flow (1216) on the access terminal (206) has been received from the access network (204). If the current power allocation grant (1374) is still active, a current power allocation (1338a) for the flow is set equal to the current power allocation grant (1374). If the current power allocation grant (1374) has not been received, the current power allocation (1338a) for the flow is determined.

Abstract: An apparatus for selecting a best serving sector in a code division multiple access (CDMA) communication system. A comparator compares a plurality of signal levels received from a plurality of active sectors with a signal level of a current serving sector to produce a difference. A delta generator is coupled to the comparator that generates a delta credit for each of the plurality of active sectors based on the difference. An accumulator is coupled to the delta generator and accumulates a plurality of delta credits to produce an accumulated total credit. A best sector identifier that is coupled to the accumulator identifies the best serving sector from the accumulated total credit.

Abstract: Reverse Link (RL) data rate allocation in a High Data Rate (such as 1xEV-DO) system as a function of Forward Link (FL) channel quality. Rate shaping of a throughput profile for multiple Access Terminals (ATs) is performed by adjusting transition probabilities associated with a data rate allocation algorithm. The RL maximum data rate per AT is adjusted to reduce the loading in a designated area and result in rate shaping of the cell and/or sector. In one embodiment, the maximum data rates are adjusted as a function of the FL Signal to Interference and Noise Ratio (SINR), such as measured per serving sector or as a captured sum total of FL SINR. In still another embodiment, the maximum data rates are adjusted as a function of differences in riseover-thermal values between neighboring sectors.

Abstract: In a method for packet data transmission from at least one Access Point to an Access Terminal, data request messages are received from a plurality of Access Terminals. A transmission of data from the Access Terminal having the highest ratio of requested data rate to average served rate is scheduled, and an Access Point transmits data at a randomly varying transmit power, or at a transmit power in synchronism with neighbouring Access Points, in accordance with the data request message.

Abstract: In a data communication system capable of variable rate transmission, the da ta rate is determined by the largest C/I measurement of the forward link signal s as measured at the Access Terminal (6). In one embodiment, the date transmission is scheduled based on an Access Terminal (6) initiated forward power control, which reduces forward link rate quantization loss due to exce ss transmit power. The Access Terminal (6) reports to the Access Point (4) the excess C/I estimate for the selected rate. The Access Point (4) then reduces its transmit power by an appropriate amount when serving that Access Termina l (6). In another embodiment, the data transmission is scheduled based on an Access Point (4) initiated forward power control. The Access Point (4) varie s its transmit power over time either randomly or in synchronism with neighboring Access Point (4) in the communication system, which enables an increase in the throughput achieved by users that receive a significant amou nt of interference.

Abstract: In a high data rate communication system capable of variable rate transmission, an open loop rate control can be adjusted with a closed loop rate control to maximize throughput. An access point generates interleaved multi-slot packets that allow an access terminal to transmit indicator messages to the access point in accordance with recently received data carried within slots of the multi-slot packets.
