摘要： Systems and methodologies are described that facilitate scheduling via a power control algorithm that dynamically update a scheduling metric (e.g., adjusting transmission power for sub-carriers) based on a prediction function and/or inference model of expected power requirements. In one aspect, the power prediction component can include two further components, namely: the data channel component and the control channel component—wherein a carrier to interference ratio (C/I) information is being transmitted on such control channel and the power is adjusted to obtain performance requirements. Accordingly, an efficient scheduling of users on a reverse link in an orthogonal manner can be provided, to optimally use system resources, while simultaneously: maintaining a predetermined and/or arbitrary fairness metrics, maintaining quality of service and maximizing throughput.

摘要： In a channel switching scheme for wireless communication, when a wireless device transmitting and/or receiving user data of a first type via a first channel needs to switch to transmitting and/or receiving user data of a second type, a second channel is established for the second type of user data. To reduce latency and interference that may otherwise be associated with such a switch, at least one parameter for communicating on the second channel is sent over the first channel. The wireless device that receives the parameters(s) may immediately commence taking action to switch to the second channel. In addition, the wireless device that sent the parameter(s) may concurrently tear down the first channel while establishing the second channel.

摘要： Systems and methodologies are described that facilitate mitigating a hidden node condition in a wireless mesh network wherein nodes utilize a request-to-send/clear-to-send (RTS/CTS) protocol in conjunction with an asynchronous hybrid automatic repeat request protocol. For instance, a node may contend for a set of subcarriers by sending an RTS signal over the desired subcarriers, and may receive a CTS signal over the contended subcarriers, wherein the CTS signal indicates which subcarriers the node may transmit data over. If another node has won the contention for a particular subcarrier, requesting node may adjust a power level at which it transmits an RTS or a data packet in order to permit the requesting node to utilize the subcarrier without interfering with the winning node.

摘要： Techniques for adjusting transmit power to mitigate both intra-sector interference to a serving base station and inter-sector interference to neighbor base stations are described. The amount of inter-sector interference that a terminal may cause may be roughly estimated based on the total interference observed by each neighbor base station, channel gains for the serving and neighbor base stations, and the current transmit power level. The transmit power may be decreased if high interference is observed by a neighbor base station and increased otherwise. The transmit power may be adjusted by a larger amount and/or more frequently if the terminal is located closer to the neighbor base station observing high interference and/or if the current transmit power level is higher, and vice versa. The intra-sector interference is maintained within an acceptable level by limiting a received SNR for the terminal to be within a range of allowable SNRs.

摘要： Systems and methods are disclosed that facilitate wireless communication using resource utilization messages (RUMs), in accordance with various aspects. A RUM may be generated for a first node, such as an access point or an access terminal, to indicate that a first predetermined threshold has been met or exceeded. The RUM may be weighted to indicate a degree to which a second predetermined threshold has been exceeded. The first and/or second predetermined thresholds may be associated with various parameters associated with the node, such as latency, throughput, data rate, spectral efficiency, carrier-to-interference ratio, interference-over-thermal level, etc. The RUM may then be transmitted to one or more other nodes to indicate a level of disadvantage experienced by the first node.

摘要： Disclosed is a method for verifying data packet integrity in a streaming-data channel. In the method, data packets are received from the streaming-data channel. Each data packet includes a data payload and a corresponding message integrity code. The received data packets are processed in a first processing mode, wherein the received data packets are forwarded to an application module before checking the integrity of the data packets using the respective message integrity codes. An integrity-check-failure measurement is generated for monitoring an integrity-check-failure rate in the first processing mode. If the integrity-check-failure measurement exceeds an integrity-check threshold, then the method transitions to a second processing mode. A received data packet is forwarded to the application module in the second processing mode only after passing the integrity check.

摘要： An apparatus for data communication that receives a plurality of pulses from a remote communications device, determines a pulse puncturing rate based on the pulses, and punctures or discards subsequent pulses based on the pulse puncturing rate. During intervals when punctured pulses are expected, the apparatus operates in a lower power consumption mode for the purpose of conserving power. In another aspect, a receiving apparatus determines the pulse puncturing rate based on received pulses, and transmits the pulse puncturing rate information to a transmitting apparatus. In response, the transmitting apparatus sends a subset of the pulses it would have transmitted based on the pulse puncturing rate. Because the receiving apparatus receives fewer pulses (e.g., a subset), the receiving apparatus may operate in a lower power consumption mode for longer periods in order to conserve power. Similarly, because the transmitting apparatus sends fewer pulses, it may also operate in a lower power consumption mode for longer periods.

摘要： In a pulse-based communication system a transmitting device may generate a series of pulses to convey information via a communication medium to a receiving device. In some situations, interference from one or more interfering devices may alter the pulse energy as it is transmitted through the communication medium. To mitigate the effect of such interference, a receiving device may mark certain received pulses as erasures. In this way, such pulses may be ignored during the decoding operation of the receiver.
