MULTI-USER POWER CONTROL METHODS AND PROCEDURES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18233940 titled 'MULTI-USER POWER CONTROL METHODS AND PROCEDURES
Simplified Explanation
This patent application describes methods and systems for operating in a WLAN, specifically focusing on a transmit power control (TPC) scheme. The goal is to improve the synchronization and scheduling of uplink multi-user transmissions.
- The access point (AP) sends a trigger frame to one or more stations (STAs) to coordinate their transmissions.
- The trigger frame includes an open-loop power control index 1 and a power adjustment index 2.
- The STAs use the indicated AP transmit power and received power to estimate pathloss and set a baseline transmit power.
- During the uplink transmission period, the STAs adjust their transmit power to match the indicated target receive power at the AP.
Original Abstract Submitted
Methods and systems for operation in a WLAN are provided. Methods and systems for a transmit power control (TPC) scheme are disclosed. In an embodiment, an access point (AP) may send a trigger frame to one or more stations (STAs) for synchronizing and scheduling uplink (UL) multi-user (MU) transmissions. The trigger frame may contain an open-loop power control index 1 and a power adjustment index 2. The one or more STAs may estimate pathloss using an indicated AP transmit power and received power to set a baseline transmit power. The one or more STAs may adjust their transmit power in the UL transmission period to be the indicated target receive power at the AP.
