Abstract
A wireless communication method and apparatus in a wireless local area network (WLAN) system are disclosed. A wireless communication method according to one embodiment may include generating a high-efficiency Wi-Fi (HEW) frame including at least one of an HEW-SIG-A field and an HEW-SIG-B field which include channel information for communications according to an Orthogonal Frequency-Division Multiple Access (OFDMA) mode, and transmitting the generated HEW frame to a reception apparatus.
Claims12
A wireless communication method performed by a wireless communication apparatus in a wireless local area network (WLAN) system, the wireless communication method comprising:
- generating a frame comprising an SIG-A field and an SIG-B field, wherein the SIG-B field comprises bit information that comprises subchannel allocation information in an Orthogonal Frequency-Division Multiple Access (OFDMA) mode where different subchannels are allocated to different users and simultaneous data transmission to multiple users is allowed;
- and
- transmitting the generated frame to the multiple users,
- wherein the subchannel allocation information in the OFDMA mode comprises allocation information on subchannels not adjacent.
A wireless communication method performed by a wireless communication apparatus in a wireless local area network (WLAN) system, the wireless communication method comprising:
- receiving, by the wireless communication apparatus corresponding to one of multiple users from a transmission apparatus, a frame comprising an SIG-A field and an SIG-B field, wherein the SIG-B field comprises bit information that comprises subchannel allocation information in an Orthogonal Frequency-Division Multiple Access (OFDMA) mode where different subchannels are allocated to different users and simultaneous data transmission to the multiple users is allowed;
- and
- determining each of subchannels to be used for communications based on at least the subchannel allocation information,
- wherein the subchannel allocation information in the OFDMA mode comprises allocation information on subchannels not adjacent.
A wireless communication apparatus comprising:
- a processor to generate a frame comprising an SIG-A field and an SIG-B field, wherein the SIG-B field comprises bit information comprising subchannel allocation information in an Orthogonal Frequency-Division Multiple Access (OFDMA) mode where different subchannels are allocated to different users and simultaneous data transmission to multiple users is allowed;
- and
- a transmitter to transmit the generated frame to the multiple users,
- wherein the subchannel allocation information in the OFDMA mode comprises allocation information on subchannels not adjacent.
