Abstract:
1. A method comprising, establishing a peer-to-peer bi-directional service period between a pair of peer-to-peer wireless communication devices neither of which is an access point, wherein the pair of peer-to-peer wireless communication devices comprise a first wireless communication device and a second wireless communication device communicating directly with each other in an ad hoc wireless communication network; receiving at the second wireless communication device a first end of service period indication from the first wireless communication device, said first end of service period indication being effective to indicate to the second wireless communication device that the first wireless communication device does not have data left to transmit during the bi-directional service period; keeping the bi-directional service period open for communication of data between the first wireless communication device and the second wireless communication device until a second end of service period indication is transmitted from the second wireless communication device to the first wireless communication device, the second end of service period indication being effective to indicate to the first wireless communication device that the second wireless communication device does not have data left to transmit during the bi-directional service period; and terminating the bi-directional service period in response to transmitting the second end of service period indication to the first wireless communication device so that the peer-to-peer bi-directional service period does not end and communication of data is kept open until a first end of service period indication is received by the second wireless communication device from the first wireless communication device and the second end of service period indication is transmitted from the second wireless communication device to the first wireless communication device.
