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： 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： This disclosure provides systems, methods and apparatuses for pre- and post-packet detection interference nulling. In some implementations, a method includes detecting at least a first part of an unscheduled Wi-Fi packet and performing a channel estimation. The method also may include estimating an interference on the Wi-Fi channel based on a known non-zero portion of the preamble of the Wi-Fi packet and nulling interference from the Wi-Fi channel during reception of at least a second part of the Wi-Fi packet. In some implementations, the method can determine an interference estimate based on at least one of a previously received packet or channel sampling for a Wi-Fi channel and computer a filter based at least in part on the interference estimate. The method also includes applying the filter to a received signal to null interference on the Wi-Fi channel at least before detection of a Wi-Fi packet.
