    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.

    摘要: In a wireless communication system, an apparatus and a method are provided for controlling reverse link interference among access terminals that are power controlled by a sector of a base station. In an embodiment, the maximum effective noise power spectral density is used as a parameter for controlling the level of reverse link loading, by setting a reverse activity bit (RAB) to signal the access terminals to reduce their data rates in order to minimize interference between the access terminals if the maximum effective noise power spectral density is above a predetermined threshold.

    摘要: Methods and apparatus for a data transmission in a communication system are disclosed. Each of a subset of plural access terminals desiring to transmit user data in an interval transmits a request to transmit in the interval to an access network. The access network makes a decision to schedule at least one of the subset of the plural access terminals to transmit in the interval in accordance with the request. At least one access point of the access network transmits the decision to the plural access terminals.

    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.
