Abstract:
1. A method comprising: determining if a previous exchange, during which a previous clear-to-send packet was transmitted to an access point at a previous time, between a station and the access point was successful, wherein the station operates simultaneously using a first protocol and at least a second protocol, wherein communication between the station and the access point occurs in a first protocol, the access point unable to transmit data packets to the station without receiving a poll packet, wherein the station also communicates using the second protocol, and wherein the station uses the first protocol before a first threshold and the second protocol after the first threshold, and wherein a first duration between the second threshold and the first threshold is at least of sufficient length for the station to receive one data packet from the access point and send an acknowledgment; and if there is no previous transmission, transmitting a current clear-to-send packet, to the access point at the second threshold and at a current time during a current exchange based on the determination, wherein the access point is unable to transmit data packets to the station without receiving a poll packet and wherein the second threshold is before the first threshold.
