Abstract
A system and method for maintaining timing compatibility for high rate wireless transceivers employs a cycle stealing technique so that latencies introduced by multi-antenna signal processors in an access point can be masked. A speculative pre-stored, predetermined preamble is issued in response to a data transmission initiation from another access point, so that a responsive packet is sent within an acceptable protocol timing interval.
Claims29
A latency compensation circuit for use in a first wireless access point operating in accordance with a communications protocol comprising:
- a first acquisition circuit configured to identify receipt of a first data packet from a second wireless access point;
- and
- a speculative response circuit configured to issue a speculative response to said first data packet to said second wireless access point,
- wherein said first wireless access point is configured to transmit said speculative response before said first wireless access point has completed a packet decoding operation on said first data packet.
A circuit for use in a first access point comprising:
- a first circuit configured to identify receipt of a first data packet;
- a second circuit configured to issue a response to the first data packet;
- and
- wherein the first access point is configured to transmit the response before the first access point has completed a packet decoding operation on the first data packet.
A system for use in a first access point comprising:
- a terminal configured to communicate with at least a second access point;
- a first circuit configured to identify receipt of a first data packet;
- a second circuit configured to issue a response to the first data packet;
- and
- wherein the terminal is configured to transmit the before the first access point has completed a packet decoding operation on the first data packet.
An apparatus comprising:
- means for identifying receipt of a first data packet;
- means for issuing a response to the first data packet;
- and
- means for transmitting a response before decoding the first data packet.
An apparatus for use in a first access point comprising:

- means for identifying receipt of a first data packet;
- means for issuing a response to the first data packet;
- and
- means for transmitting a response before decoding the first data packet.
A method comprising:
- identifying receipt of a first data packet;
- issuing a response to the first data packet;
- and
- transmitting a response before decoding the first data packet.
