PCP handover in a mesh network after a change of role of a station associated with a first node receiving from another node an indication of association
A station (STA) may include an antenna and a processor operatively coupled to the antenna. The antenna and the processor may be configured to receive a request message from an access point (AP). The request message may include identity information of one or more other STAs and an indication to perform measurements of the one or more other STAs. The antenna and the processor may be further configured to perform the measurements of the one or more STAs to determine a link metric associated with each STA of the one or more other STAs. The antenna and the processor may be further configured to send a reply message to the AP after the link metric associated with each STA of the one or more STAs is determined. The reply message may include results of the determination.
1. A station (STA) for use in a wireless network, the STA comprising:
an antenna; and
a processor operatively coupled to the antenna;
the antenna and the processor configured to receive a first request message from an access point (AP), the first request message comprising identity information of one or more other STAs, an indication to perform beamforming measurements of the one or more other STAs, and an indication to request measurement feedback from the STA;
the antenna and the processor further configured to perform, based on the identity information, the beamforming measurements of the one or more other STAs by:
transmitting, to the one or more other STAs, one or more second request messages, wherein each of the one or more second request messages includes an indication to perform beamforming measurements of the one or more other STAs and an indication to request measurement feedback from the one or more other STAs; and
receiving, from the one or more other STAs, one or more first reply messages, wherein each of the one or more first reply messages includes first link metric information associated with each STA of the one or more other STAs, wherein the first link metric information includes the measurement feedback from the one or more other STAs; and
the antenna and the processor further configured to send, to the AP, a second reply message including the first link metric information and second link metric information associated with the STA, wherein the second link metric information includes the measurement feedback from the STA.
2. The STA of claim 1 , wherein the beamforming measurements comprise directional measurements.
3. The STA of claim 1 , wherein the first link metric information further comprises route information.
4. The STA of claim 1 , wherein the first request message further comprises medium access control (MAC) addresses of the one or more other STAs.
5. The STA of claim 1 , wherein the STA and the one or more other STAs are in a same personal basic service set (PBSS).
6. The STA of claim 1 , wherein a STA of the one or more other STAs is in a different PBSS than the STA.
7. The STA of claim 1 , wherein the first request message further comprises a number of the one or more other STAs.
8. The STA of claim 1 , wherein the first link metric information further comprises as signal-to-noise ratio (SNR).
9. A method for use in a station (STA) of a wireless network, the method comprising:
receiving a first request message from an access point (AP), the first request message comprising identity information of one or more other STAs, an indication to perform beamforming measurements of the one or more other STAs, and an indication to request measurement feedback from the STA;
transmitting, to the one or more other STAs, one or more second request messages, wherein each of the one or more second request messages includes an indication to perform beamforming measurements of the one or more other STAs and an indication to request measurement feedback from the one or more other STAs;
receiving, from the one or more other STAs, one or more first reply messages, wherein each of the one or more first reply messages includes first link metric information associated with each STA of the one or more other STAs, wherein the first link metric information includes the measurement feedback from the one or more other STAs; and
sending, to the AP, a second reply message including the first link metric information and second link metric information associated with the STA, wherein the second link metric information includes the measurement feedback from the STA.
10. The method of claim 9 , wherein the beamforming measurements comprise directional measurements.
11. The method of claim 9 , wherein the first link metric information comprises route information.
12. The method of claim 9 , wherein the first request message further comprises medium access control (MAC) addresses of the one or more other STAs.
13. The method of claim 9 , wherein the STA and the one or more other STAs are in a same personal basic service set (PBSS).
14. The method of claim 9 , wherein a STA of the one or more other STAs is in a different PBSS than the STA.
15. The method of claim 9 , wherein the first request message further comprises a number of the one or more other STAs.
16. The method of claim 9 , wherein the first link metric information further comprises as signal-to-noise ratio (SNR).
