Initializing a transceiver in a wireless communication system

摘要

A method and apparatus for initializing a transceiver in a wireless communication system. In one embodiment, a method for initializing a transceiver that is part of an apparatus for use in a wireless communication system 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, the initialization method comprising resetting the transceiver by initializing internal hardware and software subsystems of the transceiver; after resetting the transceiver, the transceiver entering a configuration state to configure the transceiver; configuring the transceiver, such that the transceiver is configured as part of initialization; and after configuration, the transceiver entering a wait enable state during which the transceiver waits for its wireless interface to be enabled before wireless operation of the transceiver becomes active.

1. A method for initializing a transceiver that is part of an apparatus for use in a wireless communication system 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 via the interface to exchange information between the host processor and the transceiver via the interface, the initialization method comprising:
resetting the transceiver by initializing internal hardware and software subsystems of the transceiver; determining if the transceiver is ready for use after resetting based on a status of a register within the memory; the transceiver entering a configuration state to configure the transceiver if determined ready for use; configuring the transceiver, such that the transceiver is configured as part of initialization; and after configuration, the transceiver entering a wait enable state during which the transceiver waits for its wireless interface to be enabled before wireless operation of the transceiver becomes active; prior to the transceiver being visible on the wireless network, the transceiver receiving an indication that host processor capabilities information is available in the memory; responsive to receiving the indication that the host processor capabilities information is available, the transceiver accessing the memory to obtain the host processor capabilities information; and the transceiver parsing fields in the host processor capabilities information; and the transceiver making itself visible on the wireless network by advertising the host process capabilities.
