摘要： Methods and apparatus for communicating transmission backlog information are described. Reporting control factors are utilized to expand reporting possibilities for a fixed bit size request report. At least one report control factor is determined as a function of channel quality information, power information, device capability information, and/or quality of service information. A transmission backlog report value is interpreted as a function of a reporting control factor. A wide range of quantization schemes for reporting transmission backlog information are facilitated corresponding to a small bit size report. A communications device can adaptively select a quantization request level closely matched to its current needs such as to provide an accurate representation of its current traffic channel resource needs. A communications device may request a number of frames in a request report and the same report may be indirectly requesting a number of communications segments needed to clear its transmission backlog.

摘要： A method for reliably transmitting signaling information is provided. One type of signaling information is transmitted over a primary control channel. The signaling information that is to be transmitted over the primary control channel is defined as a set of particular information. Other signaling information are conveyed over a secondary control channel. Prior to transmission, the information to be conveyed over the secondary channel is scrambled in accordance with a particular scrambling procedure that indicates the information that is to be sent over the primary control channel. The scrambling is thus used to encode the information content of the primary control channel into the information of the secondary control channel thereby further protecting the integrity of the information being conveyed over both control channels.

摘要： In a method of tracking a user in a communication network supporting a broadcast-multicast service, the network classifies groups of users into tracking areas. Movement of a user may be tracked as the user crosses a boundary between two tracking areas in the network. The method may enable a balance to be achieved between use of uplink overhead and the level or granularity of tracking desired, so as to conserve radio resources.

摘要： In a system having a base station transmitter for transmitting data blocks to one or more mobile stations over a radio link, a method for determining a transmit power level at which to transmit a current block. A quality measurement is received from a mobile station indicating an average radio link quality over a previous group of blocks, wherein not all of the blocks of the previous group of blocks were necessarily transmitted at the same transmit power level. A transmit power attenuation level is determined for the current block based on the quality measurement. The transmit power attenuation level is subtracted from the initial transmit power level to determine the transmit power level for the current block.
