Claim Text:
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.
