Abstract
Embodiments of an access point (AP) station (STA) configured for operating in a next-generation (NG) wireless local area network (WLAN) (i.e., EHT) are generally described herein. In some embodiments, a comb resource unit (RU) structure may be used to distribute tones of an RU across a wider bandwidth for narrow RU power spectral density (PSD) boosting for longer-range transmission in EHT to meet ETSI and/or FCC limitations.
Claims20
An apparatus for an access point (AP) station (STA) configured for operating in a next-generation (NG) wireless local area network (WLAN), the apparatus comprising:
- transmitter circuitry, including processing circuitry;
- and memory,
- wherein for standard range communication with a non-AP STA, the processing circuitry is configured to:
- map tones to a standard resource unit (RU);
- and allocate the standard RU to the non-AP STA, and
- wherein for increased range communication with the non-AP STA, the processing circuitry is configured to:
- map tones to a comb RU;
- and allocate the comb RU to the non-AP STA,
- wherein the standard RU comprises a tone set having a predetermined number of adjacent tones within a portion of a channel bandwidth, and
- wherein the comb RU comprises a tone set having a predetermined number of non-adjacent tones distributed across the channel bandwidth,
- encode a frame comprising an Extremely High Throughput (EHT) long training field (LTF) (EHT-LTF) for transmission to the non-AP STA, wherein tones of the EHT-LTF are transmitted in accordance with the mapping of one of the standard RU and the comb RU.
A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of an access point (AP) station (STA) configured for operating in a next-generation (NG) wireless local area network (WLAN), wherein the instructions configure the processing circuitry to:
- wherein for standard range communication with a non-AP STA, the processing circuitry is configured to:
- map tones to a standard resource unit (RU);
- and allocate the standard RU to the non-AP STA, and
- wherein for increased range communication with the non-AP STA, the processing circuitry is configured to:
- map tones to a comb RU;
- and allocate the comb RU to the non-AP STA,
- wherein the standard RU comprises a tone set having a predetermined number of adjacent tones within a portion of a channel bandwidth, and
- wherein the comb RU comprises a tone set having a predetermined number of non-adjacent tones distributed across the channel bandwidth,
- encode a frame comprising an Extremely High Throughput (EHT) long training field (LTF) (EHT-LTF) for transmission to the non-AP STA, wherein tones of the EHT-LTF are transmitted in accordance with the mapping of one of the standard RU and the comb RU.
An apparatus for an access point (AP) station (STA) configured for operating in a next-generation (NG) wireless local area network (WLAN), the apparatus comprising:
- transmitter circuitry, including processing circuitry;
- and memory,
- wherein for standard range communication with a non-AP STA, the processing circuitry is configured to:
- map tones to a standard resource unit (RU) within a channel;
- and allocate the standard RU to the non-AP STA, and
- wherein for increased range communication with the non-AP STA, the processing circuitry is configured to allocate one or more additional standard RUs (duplicated RUs) within the channel to the STA,
- wherein the processing circuitry is configured to encode a frame for transmission to the non-AP STA comprising:
- the standard RU;
- and the one or more additional standard RUs when allocated to the non-AP station for increased range communication.
