Title:
BANDWIDTH MODE INDICATION METHOD AND APPARATUS, AND CHANNEL INDICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/242658
Kind Code:
A1
Abstract:
The present application relates to the field of communications and provides a bandwidth mode indication method and apparatus, and a channel indication method and apparatus. The method comprises: if a first device is an EHT station, a second device generates a frame in a first non-HT format or a frame in a first non-HT duplicated format, at least three bits among the first seven bits of a scrambling sequence of the frame in the first non-HT format or the frame in the first non-HT duplicated format indicating a bandwidth mode of a channel; send to the first device the frame in the first non-HT format or the frame in the first non-HT duplicated format; if the first device is a VHT station or an HE station which does not supports EHT, the second device generates a frame in a second non-HT format or a frame in a second non-HT duplicated format, two bits among the first seven bits of a scrambling sequence of the frame in the second non-HT format or the frame in the second non-HT duplicated format indicating the bandwidth mode of the channel; send to the first device the frame in the second non-HT format or the frame in the second non-HT duplicated format. The present application can implement sending a new bandwidth mode to the first device.
