    摘要: An access terminal (206) configured for wireless communication with an access 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 network (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.

Instructions stored in the memory (2604) implement, for each flow (1216) of a plurality of flows on the access terminal (206), determining the flow's total available power (1238). The access terminal's total available power (1234) is determined by summing each flow's total available power (1238). A packet is transmitted to the access network (204) at a power level that does not exceed the access terminal's total available power (1234).

    摘要: A communication system (100) transmits data packets from a sender (120A) to a receiver (130A) using hybrid automatic repeat request processes. The sender redundantly encodes each packet, divides the packet into subpackets, and sends the subpackets to the receiver in a time-interlaced manner. When the receiver returns a positive acknowledgement of a subpacket using an acknowledgement channel, the sender terminates transmission of the subpackets. The sender interprets the signals on the acknowledgement channel using a metric resulting from correlation of the signals with positive and negative acknowledgement symbols. The sender interprets low correlation of the acknowledgement channel signal with both positive and negative acknowledgement symbols as a preamble miss, and terminates transmission of the subpackets. After termination, the packet may be rescheduled for transmission. Early termination of packet transmission after a preamble miss improves bandwidth utilization and decreases latency of the packet with the missed preamble.

    摘要: A communication system includes a plurality of access terminals, and an access network. The access network schedules a transmission of data in a time interval from one of the access terminals. The access network selects a multiple access transmission mode from a plurality of multiple access transmission modes, and broadcasts the selected multiple access transmission mode to the access terminals. The selected mode may include a mode in which data is code-division-multiplexed during the time interval, and modes in which data is code-division-multiplexed during a first portion of the time interval, and data is either time-division-multiplexed or orthogonal-frequency-division-multiplexed during a second portion of the time interval.

    摘要: Disclosed are methods and apparatus for interference cancellation in a wireless communication system. In particular, the disclosed methods and apparatus provide for interference cancellation in a wireless device, including extending linear interference cancellation techniques, such as quasi-linear interference cancellation (QLIC), in the wireless device to a first orthogonal set, which may be a first quasi orthogonal function (QOF) set for a cdma2000 system to cancel interference from that set upon another desired QOF set. QLIC may also be extended to cancellation of signals from non-intended base stations as well. Accordingly, the present methods and apparatus afford reduced interference through QLIC by canceling signals due to either undesired QOF sets or non-intended base stations, which in turn results in an increase in forward link capacity.

    摘要: Methods, apparatus and media for receiving emergency broadcast information in a broadcast-multicast service of a communication system. The methods, apparatus and media include scheduling a broadcast of emergency broadcast information in designated control channel cycles for designated subscriber stations. The control channel cycles are transmitted with the designated control channel cycles including the emergency broadcast information. Subscriber stations awake according to their designated control channel cycle and receive the transmission of their designated control channel cycle on a broadcast-multicast service. The subscriber station determines if emergency broadcast information is in the control channel cycle assigned to the subscriber station and responds accordingly.
