Abstract

A method and apparatus for performing device discovery in a wireless communication system is described. In one embodiment, a device discovery process is used in a wireless communication system having an apparatus for communicating with WirelessHD devices in a wireless network, where the apparatus comprises a host processor; a transceiver; a physical interface coupling the host processor and the transceiver; and a memory accessible by the host processor and the transceiver to exchange information between the host processor and the transceiver, and the device discovery process comprises: discovering a remote wireless device in the wireless network; notifying, by the transceiver, the host processor of the remote wireless device; requesting, under control of the transceiver, capability information from the remote wireless device prior to receiving a request from the host processor for the capability information; buffering, under control of the transceiver, the capability information before the capability information is requested by the host processor; receiving a capability request from the host processor; and providing the host processor access to the capability information.
