摘要： Techniques for performing erasure detection and power control for a transmission without error detection coding are described. For erasure detection, a transmitter transmits codewords via a wireless channel. A receiver computes a metric for each received codeword, compares the computed metric against an erasure threshold, and declares the received codeword to be “erased” or “non-erased”. The receiver dynamically adjusts the erasure threshold based on received known codewords to achieve a target level of performance. For power control, an inner loop adjusts the transmit power to maintain a received signal quality (SNR) at a target SNR. An outer loop adjusts the target SNR based on the status of received codewords (erased or non-erased) to achieve a target erasure rate. A third loop adjusts the erasure threshold based on the status of received known codewords (“good”, “bad”, or erased) to achieve a target conditional error rate.
摘要翻译：描述了用于对没有错误检测编码的传输进行擦除检测和功率控制的技术。为了擦除检测，发射机经由无线信道发送码字。接收机计算每个接收到的码字的度量，将所计算的度量与擦除阈值进行比较，并将接收的码字声明为“擦除”或“未擦除”。接收机基于接收到的已知码字来动态地调整擦除阈值，以实现目标性能水平。对于功率控制，内部环路调整发射功率以将接收信号质量（SNR）保持在目标SNR。外部环路基于接收到的码字（擦除或未擦除）的状态来调整目标SNR以实现目标擦除率。第三循环基于接收的已知码字的状态（“好”，“坏”或被擦除）来调整擦除阈值，以实现目标条件错误率。

摘要： In a signal-based gain control scheme, one or more gain levels used for processing signals are selected based on characteristics of previously received signals. For example, different gain levels may be used to receive sets of signals whereupon certain characteristics of the received sets of signals are determined. One or more gain levels are then selected based on these characteristics whereby another signal is processed based on the selected gain level(s). In some aspects, the signal-based gain control scheme may be employed to facilitate two-way ranging operations between two devices. For example, leading edge detection may involve determining a characteristic of a received signal, determining a threshold based on the characteristic, and identifying a leading edge associated with the received signal based on the threshold. In some aspects, the signal-based gain control scheme may be employed in an ultra-low power pulse-based communication system (e.g., in ultra-wideband communication devices).

摘要： Systems and methods are described that facilitate controlling transmission/reception time slots in a wireless multi-hop ad hoc network. A node, such as an access terminal or an access point, may select an identifier that corresponds to specific time slots during which nodes with that particular identifier may transmit and/or receive. Nodes that are one hop away from each other may select different identifiers in order to ensure that neighboring nodes do not transmit and/or receive during the same time slots. In this manner, interference caused and/or experienced by a given node may be reduced.

摘要： Techniques for selecting a reverse link (RL) serving base station for a terminal are described. The terminal sends a transmission on the reverse link to multiple base stations in a wireless communication system. The transmission may be for signaling sent on a control channel. The terminal receives feedback (e.g., power control (PC) commands and/or erasure indications) from the multiple base stations. Each base station may generate feedback based on the control channel and/or some other transmission received from the terminal. The terminal performs reverse link power control and further selects an RL serving base station based on the received feedback. For example, the terminal may select the base station with the lowest transmit power level, the largest percentage of power down commands, or the lowest erasure rate as the RL serving base station.

摘要： Techniques to enhance the performance in a wireless communication system using CQI feedback optimized to support different scenarios. According to one aspect, an access terminal may select a CQI feedback table based on the access terminals capability. According to another aspect, an access point may select a CQI feedback table based on an access terminals capability, system loading and the type of service provided by the access point. An access point which provides services that require high data rates may select a larger CQI feedback table to support the high data rates for access terminals which support the larger CQI feedback table. The same access point may select a smaller CQI feedback table for access terminals which do not have the capability or need for the high data rate services.

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.
