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.

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： Systems and methodologies are described that facilitate communicating reverse link control information over OFDMA control channel(s) and CDMA control channel(s). Dedicated OFDMA control channel resources can be assigned to mobile device(s). Control information related to one or more logical control channels can be generated by a mobile device. Further, a physical control channel type (e.g., OFDMA control channel or a CDMA control channel) can be selected for sending the control information via the reverse link. For example, control information associated with periodic, logical control channels can be multiplexed and sent over the OFDMA control channel (e.g., utilizing the dedicated OFDMA control channel resources) while control information related to non-periodic, logical control channels can be transmitted over the CDMA control channel.

摘要： Methods and apparatus are described where loading information regarding loading conditions at a neighboring base station is received at a first base station and then communicated, e.g., broadcast, by the first base station to mobiles within the cell in which the first base station is located. Since the neighbor base station's loading information is being communicated to a mobile currently connected to the first base station via a reliable communications channel of the first base station, the mobile can be expected to be able to reliably recover loading factor information corresponding to not only the first base station but to the neighboring base station. By utilizing such loading factor information, the mobile can generate an improved uplink interference report. The first base station receives such interference reports from wireless terminals in its cell, facilitating efficient resource allocation and interference control.

摘要： Aspect of the present disclosure include A Mobile Ad Hoc Network (MANET) in which an intermediate relay node may engage in discreet packet-dropping practices for selfish (e.g., to conserve power) or other reasons. Each node in such a MANET has a dynamic reputation level known to all other nodes. Embodiments include improving the overall performance or robustness of such a MANET by adopting a routing strategy (e.g. routing protocol) which considers the reputation levels of intermediate relaying nodes in determining the best route from a source to a destination. Embodiments of the present disclosure also include a system for discovering a route between two nodes in a communication network. One or more nodes: (i) determine a reputation level of each neighboring node; (ii) sending a route discovery message that is addressed to the destination node to one neighboring node having a highest reputation level.

摘要： A wireless terminal measures the received power of a tone corresponding to an intention base station null output, measures the received power of pilot signals, and determines a signal to noise ratio of the received pilot signal. The wireless terminal calculates a downlink signal to noise ratio saturation level representative of the SNR of a received downlink signal that the wireless terminal would measure on a received signal transmitted by the base station at infinite power. The calculated downlink signal to noise ratio saturation level is a function of the determined interference power, the measured received pilot signal power, and the determined pilot signal SNR. A report is generated corresponding to one of a plurality of quantized levels, the selected quantized level being the closest representation to the calculated downlink signal to noise ratio saturation level. The generated report is communicated using a dedicated control channel segment in a predetermined uplink timing structure.
