摘要： A method and apparatus for determining the data rate of a reverse link communication of an access terminal includes receiving a reverse activity bit (RAB) from an access network in the communication system, and passing the RAB to multiple digital filters to produce filtered RABs. The reverse link data rate is determined based on these filtered values of the RABs. From the filtered RAB values a continuous fluid power level is determined each rate update. The access terminal maps the continuous fluid power level to actual physical transmissions by dithering among discrete power levels allowed by the physical layer.

摘要： An access terminal (AT) and a data-optimized cellular communication radio network (RN) negotiate a set of packet sizes for use on a reverse link between the AT and the RN. The negotiated set of packet sizes may differ from the default set of packet sizes defined in an existing standard, such as 1xEV-DO Revisions A and B. The packet sizes in the negotiated set may be tailored to provide a good fit with an application transmitting data on the reverse link, such as a voice encoder of a voice over Internet Protocol (VoIP) application. The AT and the RN communicate using the negotiated set of packet sizes. The packet sizes of the negotiated set may be mapped to the same reverse rate indicator (RRI) channel codewords as are defined in systems operating under the standard. Packing efficiency is thus increased, and higher capacity for delay-sensitive applications is achieved.

摘要： Methods and apparatus for selecting a serving sector in a high rate data (HDR) communication system are disclosed. An exemplary HDR communication system defines a set of data rates, at which a sector of an Access Point may send data packets to an Access Terminal. The sector is selected by the Access Terminal to achieve the highest data throughput while maintaining a targeted packet error rate. The Access Terminal employs various methods to evaluate quality metrics of forward and reverse links from and to different sectors, and uses the quality metrics to select the sector to send data packets to the Access Terminal.
