COORDINATED SPATIAL REUSE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18465752 titled 'COORDINATED SPATIAL REUSE

Simplified Explanation

The patent application describes a system where a first access point (AP) selects other APs to participate in a coordinated transmission session. The first AP transmits scheduling information to the selected APs, indicating the start times for uplink (UL) or downlink (DL) transmissions. The start times are offset from each other by a time period associated with decoding a preamble of a wireless packet. The first AP can transmit or receive wireless packets concurrently with the selected APs, based on the scheduling information.

• The first access point (AP) selects other APs to participate in a coordinated transmission session.
• The first AP transmits scheduling information to the selected APs, indicating start times for UL or DL transmissions.
• The start times are offset from each other by a time period associated with decoding a preamble of a wireless packet.
• The first AP can transmit or receive wireless packets concurrently with the selected APs, based on the scheduling information.

Potential Applications

• Improved wireless network performance and efficiency.
• Enhanced coordination between access points in a wireless network.
• Increased capacity and throughput in multi-AP environments.
• Better management of simultaneous transmissions in dense wireless networks.

Problems Solved

• Addressing interference and collisions between access points in a wireless network.
• Optimizing the use of available wireless spectrum.
• Coordinating transmissions to minimize delays and improve network performance.
• Managing concurrent transmissions in multi-AP environments.

Benefits

• Improved overall network performance and throughput.
• Enhanced reliability and reduced packet loss.
• Increased capacity and scalability in wireless networks.
• Better utilization of available wireless spectrum.

Original Abstract Submitted

In some implementations, a first access point (AP) selects one or more other APs for participation with the first AP in a coordinated access point transmission session. The first AP obtains a transmission opportunity (TXOP), and transmits a frame indicating scheduling information for uplink (UL) or downlink (DL) transmissions to or from the selected APs, the scheduling information indicating a respective start time for the UL or DL transmissions to or from the selected APs, at least two of the start times being offset from one another by a time period associated with decoding a preamble of a wireless packet. The first AP transmits or receives wireless packets to or from one or more associated stations (STAs) at least partially concurrently with the transmission or reception of wireless packets by the selected APs to or from their respective associated STAs based on the scheduling information.
