摘要： Techniques for localized dynamic channel allocation help meet the challenges of latency, memory size, and channel time optimization for wireless communication systems. As examples, advanced communication standards, such as the WiGig standard, may support wireless docking station capability and wireless streaming of high definition video content between transmitting and receiving stations, or engage in other very high throughput tasks. The techniques help to deliver the desired user experience in such an environment and address the need to meet latency and throughput requirements while limiting memory footprint.

摘要： A responder endpoint establishes a reverse direction communication channel from the responder to an initiator. To that end, the responder endpoint receives a reverse direction grant indicator and determines when primary data is not ready to be sent to the initiator. In response, the responder transmits to the initiator, within a predetermined response time for establishing the reverse direction communication channel, a continuation frame comprising a continuation indicator that indicates that reverse direction communication channel should persist. In one implementation, the continuation frame includes at least one control field including the continuation indicator, but no data payload field.

摘要： A technique for securing transmit opening helps enhance the operation of a station that employs the technique. The technique may facilitate low latency response to a protocol data requester, for instance. In one aspect, the technique provides a way for the protocol data responder to hold its transmit opening to transmit the protocol response data to the protocol data requester. The technique may allow the protocol data responder to hold the transmit opening until the protocol response data is ready and available for the protocol data responder to send.

摘要： A technique to provide frequency offset estimation for packets transmitted during a service period allocated strictly for designated source and destination devices. The destination device obtains coarse and fine frequency offset estimation from the short and long preambles. A residual frequency offset is tracked for the data blocks and combined with the coarse and fine frequency offset to obtain a total frequency offset to apply to the data blocks. The total frequency offset value at the end of the first packet is saved and, instead of again estimating the coarse and fine frequency offset values with the short and long preambles of the second packet, the saved total frequency offset value is used as the initialization value to add to the residual frequency offset in the second packet. The saved offset value at the end of each packet becomes the initialization value for the subsequent packet.
