Control channel design to support one-to-one, many-to-one, and one-to-many peer-to-peer communications
A protocol is provided that facilitates downlink concurrent peer-to-peer communications (within a time slot or traffic slot) between one device and many terminals as well as uplink concurrent peer-to-peer communications (within a time slot or traffic slot) between a plurality of terminals and one device. The concurrent peer-to-peer communications may take place within an ad hoc network of devices. To facilitate such operation, a time-frequency structure is provided within a control channel that allows the device and terminals to identify the peer-to-peer connections. This time-frequency structure also allows terminals to identify other sibling terminals that have a connection with the same device, thereby allowing to more efficiently performing interference mitigation. That is, sibling peer-to-peer connections with the same device may be treated different from other non-related peer-to-peer connects for purposes of interference mitigation in a wireless network.
