Title:
CLASSIFICATION AND SILENCING FOR UPLINK MULTI-USER TRANSMISSION IN WLAN
Document Type and Number:
Japanese Patent JP2020092465
Kind Code:
A
Abstract:
To solve a problem in which a WTRU involved in multi-user multiple input multiple output (MU-MIMO) transmission with an access point (AP) limit their operating bandwidth to the minimum channel bandwidth supported by the WTRUs included in MU-MIMO transmissions with the AP, which may result in poor uplink MU transmission.SOLUTION: There are provided a method, a device, and a system for MU transmission which includes scheduling an uplink (UL) MU transmission for a group of WTRUs in which there is an indication indicating that at least one of multiple resource units (RUs) has been silenced by an AP. Silencing can be based on making coordination with one or more overlapping access points, or performed by analyzing the condition of a channel associated with the AP.SELECTED DRAWING: Figure 2
