Abstract:
Cooperative Autonomous And Scheduled Resource Allocation For A Distributed Communication System An access terminal (206) configured for wireless communication with an access network (204) with 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 form 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. Figure 13
Abstract:
An access terminal (206) is 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 are stored in the memo ry (2604). The instructions are arranged to estimate a current value of a rever se activity bit (1444) transmitted by the access network (204). Per flow power allocation may be decreased on increased based on an estimated current value of the reverse activity bit.
Abstract:
An access network that is configured for wireless communication with an access terminal that comprises a flow. The access network comprises means for determining whether the flow is meeting at least one quality of service requirement, means for sending a grant message to the access terminal if the flow is not meeting the at least one quality of service requirement, and means for allowing the flow to autonomously set its own power allocation if the flow is meeting the at least one quality of service requirement. The grant message comprises a current power allocation grant or an accumulated power allocation grant for the flow.
Abstract:
Techniques for selecting a serving sector for a terminal based on server selection information in order to balance the load of sectors in a wireless communication system are described. The server selection information for each sector may be set based on the load of the sector and may be used to rank the sector for selection as a serving sector. In one design, a terminal may receive server selection information for multiple sectors. The server selection information for each sector may include an offset used to adjust a measurement made by the terminal for the sector, a priority of the sector for selection as a serving sector, a DRCLock set based on the load of the sector, etc. The terminal may determine received signal qualities of the sectors. The terminal may then select one of the sectors as a serving sector based on the server selection information and the received signal qualities of the sectors.
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.

In a wireless communication system where different frequency bands Fl, F2) are deployed to generate various communication zones (22,24), pilot signal set management for a plurality of pilot.Signals generated from an additional coverage zone (24) is based on identifying a preselected signal set from the plurality of pilot signals and determining whether a predetermined criterion is met.
Abstract:
A method for real-time information encoding in wireless communications is disclosed. The method includes receiving at an access terminal feedback information associated with data transmission from a wireless access module and encoding real-time information in accordance with the feedback information. The feedback information includes local feedback information available without delay from within the access terminal and end-to-end feedback information transmitted from a second receiving terminal through a wireless communications network.
