Abstract
Method and device for receiving a data unit are disclosed. A method for receiving a PPDU including a PPDU header and a data field of an STA may comprise the step of: an STA receiving the PPDU header from an AP; the STA determining whether the PPDU transfers a scanning frame on the basis of the PPDU header; and the STA determining whether to decode the data field on the basis of whether to perform a scanning procedure and whether the PPDU transfers the scanning frame.
Claims13
A method for receiving a physical layer (PHY) protocol data unit (PPDU), the method comprising:
- transmitting, by a station (STA), a first PPDU to request first association information to associate with an access point (AP) supporting the STA,
- wherein the first PPDU includes a first PPDU header and a first data field which is a remaining part of the first PPDU after the first PPDU header;
- receiving, by the STA, a second PPDU from the AP, the second PPDU including a first scanning indicator indicating whether a first scanning frame including the first association information is included in a second data field of the second PPDU,
- wherein the first scanning indicator is included in a second PPDU header of the second PPDU;
- determining, by the STA, whether to perform decoding the second data field of the second PPDU based on the first scanning indicator;
- and
- performing, by the STA, decoding the second data field if the first scanning indicator indicates that the first scanning frame is included in the second data field.
A STA for receiving a physical layer (PHY) protocol data unit (PPDU), the STA comprising:
- a radio frequency (RF) unit configured to transmit or receive radio signal;
- and
- a processor operatively connected to the RF unit and configured to:
- transmit a first PPDU to request first association information to associate with an access point (AP) supporting the STA, wherein the first PPDU includes a first PPDU header and a first data field which is a remaining part of the first PPDU after the first PPDU header;
- receive a second PPDU including a first scanning indicator indicating whether a first scanning frame including the first association information is included in a second data field of the second PPDU from the AP, wherein the first scanning indicator is included in a second PPDU header of the second PPDU;
- determine whether to perform decoding the second data field of the second PPDU based on the first scanning indicator;
- and
- perform decoding the second data field if the first scanning indicator indicates that the first scanning frame is included in the second data field.

- wherein the first scanning indicator is included in a first PPDU header of the first PPDU, and wherein the first data field which is a remaining part of the first PPDU after the first PPDU header;
- determining, by the STA, whether to perform decoding the first data field of the first PPDU based on the first scanning indicator;
- and
- performing, by the STA, decoding the first data field if the first scanning indicator indicates that the first scanning frame is included in the first data field.
