Abstract
Frame processing for a wireless communication system. The frame processing includes detecting reception of a frame based on a portion of a preamble of a frame, wherein the frame includes a preamble and a data payload. With detecting the reception of a frame, determining a frame type of a plurality of frame types from at least the portion of the preamble. Processing a remaining portion of the preamble in accordance with the frame type to determine payload processing parameters, and processing the data payload based on the payload processing parameters.
Claims16
A method of frame processing comprising:
- detecting reception of a frame based on a portion of a preamble of the frame, wherein the frame includes a preamble and a data payload;
- determining from the portion of the preamble of the frame whether the frame is a legacy frame type that corresponds to an 802.11b frame type;
- if the frame is not an 802.11b frame type, determining, based upon a modulation type, a frame type of a plurality of frame types from other portions of the preamble of the frame, wherein the plurality of frame types include legacy frame types which are not 802.11b frame types, and include non-legacy frame types, each non-legacy frame type having a dissimilar structure from remaining non-legacy frame types and supporting a high-throughput data capability;
- when the determined frame type of the frame is a non-legacy frame type, processing, based upon the determined frame type and structure, a signal field of the other portions of the preamble and a remaining portion of the preamble to determine payload processing parameters for the data payload;
- and
- processing the data payload based on the payload processing parameters.
A baseband receiver comprising:
- a processor;
- and
- memory operably coupled to the processor, wherein the memory includes operational instructions that cause the processor to:
- detect reception of a frame based on a portion of a preamble of the frame, wherein the frame includes a preamble and a data payload;
- determine from the portion of the preamble of the frame whether the frame is a legacy frame type that corresponds to an 802.11b frame type;
- if the frame is not an 802.11b frame type, determine, based upon a modulation type, a frame type of a plurality of frame types from other portions of the preamble, wherein the plurality of frame types include legacy frame types which are not 802.11b frame types, and include non-legacy frame types, each non-legacy frame type having a dissimilar frame structure from remaining non-legacy frame types and supporting a high-throughput data capability;
- when the determined frame type of the frame is a non-legacy frame type, process, based upon the determined frame type and structure, a signal field of the other portions of the preamble and a remaining portion of the preamble to determine payload processing parameters for the data payload;
- and
- process the data payload based on the payload processing parameters.
