AI Technical Summary

Technical Problem

In multi-AP wireless communication networks, existing technologies face challenges in efficiently managing resources for downlink (DL) and uplink (UL) transmissions, particularly in coordinating transmission opportunities (TXOP) across multiple access points (APs).

Method used

The proposed solution involves a method where access points (APs) share information about upcoming DL and UL transmissions, allowing for better resource management in multi-AP mode. This includes exchanging frames that indicate modulation and coding schemes (MCS), transmission opportunities (TXOP), and buffer status reports (BSR) to optimize transmission times and resource allocation.

Benefits of technology

By sharing information on upcoming transmissions, the method enhances the efficiency of resource utilization in multi-AP networks, leading to improved performance in managing DL and UL transmissions and reducing inefficiencies in TXOP allocation.

Abstract

The present invention offers ways to manage sharing transmissions in multi-AP (or BS) situations. There is provided methods, devices and computer program products. In a method there is receiving, by a first access point (AP) from a second AP, a first frame indicating a modulation and coding scheme (MCS) for a downlink (DL) transmission; and transmitting, by the first AP to the second AP, a second frame indicating an allocated time of a transmission opportunity (TXOP) obtained by the first AP; and a time period, within the allocated time, for the DL transmission, wherein the time period is determined based on the MCS. Also there is receiving, by a first access point (AP) from a second AP, a first frame indicating a downlink (DL) transmission parameter for a DL transmission; and transmitting, by the first AP to the second AP, a second frame indicating a time period for the DL transmission, wherein the time period is determined based on the DL transmission parameter.
