Abstract
A baseband circuit in a transmitting device of a WLAN may include at least one processor configured to generate a PPDU comprising a preamble and a payload. The preamble includes training fields and signaling fields, and the payload includes a data field. A first one of the signaling fields includes a compression mode field indicating whether resource unit (RU) allocation information designated for at least one receiving device is included in a second one of the signaling fields. A binary value of the compression mode field represents whether the RU allocation information is included and size information associated with the RU allocated to the at least one receiving device.
Claims21
A baseband circuit in a transmitting device of a wireless local area network (WLAN), the baseband circuit comprising:
- a storage;
- at least one processor coupled to the storage and configured to generate a physical layer convergence protocol (PLCP) protocol data unit (PPDU) comprising a preamble and a payload,
- wherein,
- the preamble comprises a plurality of training fields and a plurality of signaling fields,
- the payload comprises a data field,
- a first signaling field among the plurality of signaling fields comprises a compression mode field indicating whether resource unit (RU) allocation information designated for at least one receiving device is included in a second signaling field among the plurality of signaling fields, and
- a binary value of the compression mode field represents whether the RU allocation information is included and size information relating to a number of subcarriers associated with an RU allocated to the at least one receiving device.
A baseband circuit in a receiving device of a wireless local area network (WLAN), the baseband circuit comprising:
- a storage;
- at least one processor coupled to the storage and configured to decode a physical layer convergence protocol (PLCP) protocol data unit (PPDU) transmitted from a transmitting device to the receiving device,
- wherein,
- the PPDU comprises a preamble and a payload,
- the preamble comprises a plurality of training fields and a plurality of signaling fields,
- the payload comprises a data field,
- a first signaling field among the plurality of signaling fields comprises a compression mode field indicating whether resource unit (RU) allocation information designated for the receiving device is included in a second signaling field among the plurality of signaling fields, and
- a binary value of the compression mode field represents whether the RU allocation information is included and size information relating to a number of subcarriers associated with an RU allocated to the receiving device.
A method of wirelessly communicating in a wireless local area network (WLAN), the method comprising:
- generating, at a transmitting device, a physical layer convergence protocol (PLCP) protocol data unit (PPDU) comprising a preamble and a payload, wherein:
- (i) a first signaling field in the preamble includes a compression mode field indicating whether resource unit (RU) allocation information designated for at least one receiving device is included in a second signaling field in the preamble;
- and (ii) a binary value of the compression mode field represents whether the RU allocation information is included and, when the RU allocation information is included, size information relating to a number of subcarriers associated with an RU allocated to the at least one receiving device;
- and
- transmitting the PPDU to the at least one receiving device.
