摘要： Techniques for encoding a phase adjustment for a feedback signal in a closed-loop transmit diversity system. In an aspect, codewords for the phase adjustments are chosen according to a variable-length prefix code. The prefix code aspect allows the codewords to be transmitted in sequence on the feedback channel without being separated by “commas” or demarcation symbols. The variable-length aspect provides a variety of coarse and fine phase adjustment quantization step sizes to accommodate multiple different channel scenarios. In an aspect, the length of the codewords may be further optimized according to the Huffman encoding algorithm.

摘要： Techniques for efficiently decoding packets sent with H-ARQ are described. Packet decoding for H-ARQ may be performed based on local search around a start of packet (SOP) decision for a packet. The SOP decision for the packet may be made based on traffic detection results for received transmissions. At least one SOP hypothesis may be determined for the packet based on the SOP decision, and the received transmissions may be decoded based on the at least one SOP hypothesis. A sliding SOP window may be used to keep track of SOP hypotheses for the packet. The sliding window may be initialized at an earliest received transmission, moved forward for each subsequent received transmission with no detected packet data, and maintained at the first received transmission with detected traffic. Rotating buffers may be used to store received transmissions for packets for decoding.
摘要翻译：描述了用H-ARQ发送的分组的有效解码技术。可以基于关于分组的分组开始（SOP）决定的本地搜索来执行用于H-ARQ的分组解码。可以基于接收到的传输的业务检测结果来对分组进行SOP决定。可以基于SOP决定为分组确定至少一个SOP假设，并且可以基于至少一个SOP假设来解码所接收的传输。可以使用滑动SOP窗口来跟踪分组的SOP假设。滑动窗口可以在最早接收到的传输下被初始化，对于每个随后的接收到的传输而向前移动，没有检测到的分组数据，并且在检测到的业务量下保持在第一个接收到的传输。旋转缓冲器可以用于存储用于解码的分组的接收的传输。

摘要： Aspects described a low receiver complexity approach for reliable packet decoding when Hybrid ARQ protocol is employed with persistent assignment and potentially an erasure sequence transmission. Multiple hypotheses packet decoding performance is achieved while mitigating multiple hypotheses receiver complexity. A reference number is utilized to perform hypotheses. The reference number is independent of a start of packet. A sequence of reference numbers can be utilized, which may not necessarily be sequential numbers. The reference numbers are pre-defined.

摘要： Techniques for dynamically managing receiver resources to achieve good latency and throughput performance are described. A receiver may have various types of receiver resources such as demod resources for demodulating packets, decode resources for decoding packets, packet processing resources, etc. These various types of receiver resources may be dynamically assigned to packets. In one design, receiver resource usage by each packet to be processed by the receiver may be estimated. The available receiver resources may be assigned to packets based on the estimated receiver resource usage by each packet and one or more assignment criteria such as priority, latency requirements, etc. The latency of each packet may be determined based on the receiver resource assignment. If the latency requirements of any packet are not met, then receiver processing may be skipped or deferred for one or more packets such that the latency requirements of each packet to be processed can be met.
摘要翻译：描述了用于动态管理接收机资源以实现良好延迟和吞吐量性能的技术。接收机可以具有各种类型的接收机资源，例如用于解调分组的解调资源，用于解码分组的解码资源，分组处理资源等。这些各种类型的接收机资源可以动态地分配给分组。在一种设计中，可以估计由接收机处理的每个分组的接收机资源使用。可以基于每个分组的估计的接收机资源使用和一个或多个分配标准（例如优先级，等待时间要求等）将可用接收机资源分配给分组。可以基于接收机资源分配来确定每个分组的等待时间。如果不满足任何分组的等待时间要求，则可以针对一个或多个分组跳过或延迟接收机处理，从而可以满足要处理的每个分组的等待时间要求。

摘要： Systems and methodologies are described that facilitate reliably receiving a sequence of data packets in a wireless communications environment. In particular, mechanisms are provided that enhance hybrid automatic repeat request protocols through validation of acknowledgment message detection by re-decoding. A transmitter sends a data packet from a sequence of packets in one or more data transmissions. A receiver acknowledges the data packet upon obtaining sufficient transmissions to decode the packet. The receiver re-decodes a successive data transmission in combination with previously received transmissions to validate if the transmitter detected the acknowledgment.
