摘要:
Wireless communications devices, e.g., peer to peer mobile wireless terminals in and ad-hoc peer to peer communications network, support multiple modes of peer discovery operation. In different peer discovery transmit modes peer discovery information is transmitted at different rates. In different peer discovery receive modes peer discovery information is monitored at different rates. Performing peer discovery operations at a higher rate has the benefit of reducing discovery latency at the cost of utilizing more communications resources and expending more power. A communications device dynamically changes its mode in response to changing conditions and/or needs. Transitions between modes are in response to a determined change condition trigger occurrence. Various change condition triggers include, e.g., a user event, an application event, information received over the air interface, information derived from information received over the air interface and/or temporal information.
