Communication between wireless devices capable of communicating using multiple mac protocols

A method by which a second wireless device communicates with a first wireless device, both of said first wireless device and said second wireless device being enabled to communicate with each other using a first MAC protocol and a second MAC protocol, said method comprising:

• receiving, at a first time instance, an indication that said first wireless device is transitioning to a power savings mode in the operation of a first receiver corresponding to said first MAC protocol, wherein said first receiver is incapable of receiving data in said power savings mode;
• receiving a data unit for transmission to said first wireless device;
• sending, at a second time instance, an indication using said second MAC protocol to said first wireless device, wherein said indication indicates that data is available to be transmitted to said first wireless device from said second wireless device;
• after sending of said indication, transmitting said data unit to said first wireless device using said first MAC protocol.

A wireless device comprising:

• a first transceiver block comprising a first transmitter and a first receiver, each operating according to a first MAC protocol;
• a second transceiver block comprising a second transmitter and a second receiver, each operating to a second MAC protocol;
• a processor operable to perform the actions of:
• receiving at a first time instance, via said first receiver, an indication that a third receiver of another wireless device is transitioning to a power savings mode, wherein said third receiver operates according to said first MAC protocol, wherein said third receiver is incapable of receiving data in said power savings mode;
• receiving a data unit for transmission to said another wireless device;
• sending at a second time instance, via said second transmitter, an indication to a fourth receiver of said another wireless device, wherein said indication indicates that data is available to be transmitted to said another wireless device from said wireless device, wherein said fourth receiver operates according to said second MAC protocol;
• and
• after sending of said indication, transmitting via said first transmitter, said data unit to said another wireless device, wherein said another wireless device receives said data unit via said third receiver.
