Abstract
An apparatus implemented in an access point (AP) participates in joint soundings together with one or more other APs in a joint multi-AP (JMAP) configuration to receive joint feedbacks from a plurality of stations (STAs) responding to the joint soundings. The apparatus then performs transmissions in a coordinated multi-AP (CMAP) configuration with the one or more other APs or in a single-AP configuration with no other AP based on the joint feedbacks received while in the JMAP configuration.
Claims18
A method implemented in an access point (AP), comprising:
- participating in joint soundings together with one or more other APs in a joint multi-AP (JMAP) configuration to receive joint feedbacks from a plurality of stations (STAs) responding to the joint soundings;
- and
- performing transmissions in a coordinated multi-AP (CMAP) configuration with the one or more other APs or in a single-AP configuration with no other AP based on the joint feedbacks received while in the JMAP configuration,
- wherein the performing of transmissions in the CMAP configuration or in the single-AP configuration comprises reconfiguring to perform the transmissions in the CMAP configuration or in the single-AP configuration using the joint feedbacks received from the plurality of STAs while in the JMAP configuration with no extra information.
A method implemented in an access point (AP), comprising:
- participating in sequential or joint soundings together with one or more other APs in a coordinated multi-AP (CMAP) configuration to receive feedbacks from a plurality of stations (STAs) responding to the sequential or joint soundings;
- and
- performing transmissions in a joint multi-AP (JMAP) configuration with the one or more other APs or in a single-AP configuration with no other AP based at least in part on the feedbacks received while in the CMAP configuration,
- wherein the participating comprises participating in sequential soundings, and
- wherein the performing of transmissions in the JMAP configuration or in the single-AP configuration comprises reconfiguring to perform the transmissions in the JMAP configuration or in the single-AP configuration using joint feedbacks received from the plurality of STAs while in the CMAP configuration with no extra information.
A method, comprising:
- participating, by an apparatus implemented in an access point (AP), in joint soundings together with a first set of APs in a joint multi-AP (JMAP) configuration to receive joint feedbacks from a plurality of stations (STAs) responding to the joint soundings;
- and
- performing, by the apparatus, transmissions in a reduced JMAP configuration with a second set of APs based on the joint feedbacks received while in the JMAP configuration with no additional feedback information,
- wherein the first set of APs has more APs than the second set of APs, and
- wherein the joint feedbacks received from the plurality of STAs comprise joint channel state information (CSI) from the plurality of STAs.
