Abstract

Various methods and systems are provided for time domain coexistence of RF signals. In one example, among others, a method includes obtaining access to a WLAN channel during a free period of a coexisting cellular connection, providing a RDG to allow another device to transmit for a duration corresponding to at least a portion of a TXOP, and receiving a transmission during the duration. In another example, a method includes obtaining access to a WLAN channel during a transmission period of a coexisting cellular connection and providing a protection frame to defer transmissions from another device for a duration corresponding to at least a portion of a TXOP. In another example, a method includes determining a shift of a BT transaction based at least in part upon a schedule of cellular communications and shifting at least a portion of the BT transaction based upon the determined shift.

Dependent claims

A method, comprising:

obtaining, by a communication device supporting coexisting wireless local area network (WLAN) and cellular communications, contention free access to a WLAN channel during a traffic free period of a coexisting cellular connection;
providing, by the communication device, a reverse direction grant (RDG) to another device of the WLAN allowing the other device to transmit over the WLAN channel for a duration corresponding to at least a portion of a transmit opportunity (TXOP) of the traffic free period of the coexisting cellular connection;
and
receiving, by the communication device, a transmission from the other device of the WLAN for at least a portion of the duration.
