Method and apparatus for configuring signal field used for multiple resource units in wireless LAN system
First Claim
1. A method for transmitting a signal including control information in a wireless LAN system, the method performed by a transmitting station and comprising:
- configuring a first signal field;
configuring a second signal field indicating allocation information related to a plurality of resource units (RUs) including a first resource unit (RU) and a second RU; and
transmitting a physical layer protocol data unit (PPDU) including the first signal field, the second signal field, and a data field,wherein a number of tones corresponding to the first RU is larger than a number of tones corresponding to the second RU,wherein the first signal field includes information for demodulating the second signal field, andwherein the second signal field includes bitmap information indicating an RU positioned in units of the first RU within an entire band, MU-MIMO indication information indicating whether part of an entire band is allocated for a plurality of receiving stations through a MU-MIMO scheme, and RU allocation information indicating in units of the second RU remaining RUs excluding the RU indicated by the bitmap information.

Abstract
The present specification suggests a method and an apparatus regarding first and/or second signal fields used in a wireless LAN system. When multiple resource units are used for a specific band, a bit map field may be configured first by a resource unit having a first size, and for the remaining bands, allocation information may be configured by a resource unit having a second size. Also, a bit map field which indicates whether MU-MIMO technique is applied to the specific band or not can be further included. For example, the resource unit having the first size may comprise 242-RU and the resource unit having the second size may comprise 26-RU. A specific resource unit to which the MU-MIMO technique is applied may be 106-RU or more. When discontinuous channel bonding is an issue, additional changes can be made to the first/second signal fields of the present specification.
