Securing transmit openings

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.

主权项

1. A method comprising:
determining, at a reverse-direction responder, when a transmit opening exists in a contention-based wireless communication session; determining that response data is not yet ready to send during the transmit opening; responsive to the determination that the response data is not yet ready, determining a response length, the response length accounting for an expected amount of the response data and a holding duration to obtain the response data for sending; holding, at the reverse-direction responder, the transmit opening by transmitting a holding transmission with a transmission length determined responsive to the holding duration, instead of the response data, the holding transmission comprising a header indicating the transmission length; and when the response data is available, transmitting, during the contention-based wireless communication session, the response data instead of the holding information.
