Method for managing a wireless passive optical network

1. A method for managing a wireless passive optical network (WPON) comprising a plurality of access points (APs) and a plurality of customer premises equipments (CPEs) the method comprising:

configuring an AP to CPE association based on a load balancing algorithm such that each CPE of the plurality of CPEs is associated with at least one AP of the plurality of APs; and

configuring, for each AP of the plurality of APs, an AP beamforming codebook based on the configured association,

wherein the AP beamforming codebook comprises entries wherein each entry represents a beam pattern to be transmitted by the AP, and

wherein the AP beamforming codebook comprises, for each CPE associated with the respective AP,

a line of sight (LoS) entry representing a beam pattern to be transmitted to the respective CPE via a LoS path between the AP and the respective CPE, and

at least one back-up entry representing a beam pattern to be transmitted to the respective CPE via a back-up path which is different from the LoS path.

2. The method according to claim 1 , wherein the at least one back-up entry comprises a reflection entry resenting a beam pattern to be transmitted to the respective CPE via a reflected path.

3. The method according to claim 1 ,

wherein the at least one back-up entry comprises a relay entry representing a beam pattern to be transmitted to the respective CPE via a relay path, and

wherein at least one CPE of the plurality of CPEs other than the respective CPE or at least one AP of the plurality of APs other than the respective AP, or both, is used as a relay.

4. The method according to claim 1 , further comprising:

scanning the WPON for at least one of changes in AP configuration or changes in CPE configuration; and

triggering the configuring of the AP to CPE association when at least one of an AP is added to the WPON, an AP is removed from the WPON, a CPE is added to the WPON, or a CPE is removed from the WPON.

5. The method according to claim 1 , wherein the configuring the AP to CPE association is performed periodically.

6. The method according to claim 1 , further comprising:

configuring, for at least one CPE of the plurality of CPEs, a CPE beamforming codebook based on the configured association,

wherein the CPE beamforming codebook comprises entries, and

wherein each entry represents a beam pattern to be transmitted by the at least one CPE.

7. The method according to claim 1 , wherein the configuring the AP to CPE association comprises at least one of de-associating a CPE from an AP, re-associating a CPE to an AP, associating a CPE to an AP, or any combination thereof.

8. The method according to claim 1 , wherein the configuring the AP beamforming codebook comprises associating an identifier of the respective CPE with each entry for a respective CPE.

9. The method according to claim 1 ,

wherein the configuring the AP beamforming codebook comprises configuring multiple AP codebooks per AP, and

wherein each AP codebook corresponds with a subset of CPEs from the plurality of CPEs.

10. A wireless passive optical network (WPON) managing system for managing a WPON comprising a plurality of access points (APs) and a plurality of customer premises equipments (CPEs), the system comprising a controller configured to:

configure an AP to CPE association based on a load balancing algorithm such that each CPE of the plurality of CPEs is associated with at least one AP of the plurality of APs; and

configure, for each AP of the plurality of APs, an AP beamforming codebook based on the configured association,

wherein the AP beamforming codebook comprises entries wherein each entry is representative for a beam pattern to be transmitted by said AP, and

wherein the AP beamforming codebook comprises, for each CPE associated with the respective AP,

a line of sight (LoS) entry representing a beam pattern to be transmitted to the respective CPE via a LoS path between the AP and the respective CPE, and

at least one back-up entry representing a beam pattern to be transmitted to the respective CPE via a back-up path which is different from the LoS path.

11. The managing system according to claim 10 , wherein the at least one back-up entry comprises a reflection entry representing a beam pattern to be transmitted to the respective CPE via a reflected path.

12. The managing system according to claim 10 ,

wherein the at least one back-up entry comprises a relay entry representing a beam pattern to be transmitted to the respective CPE via a relay path, and

wherein at least one CPE of the plurality of CPEs other than the respective CPE or at least one AP of the plurality of APs other than the respective AP, or both, is used as a relay.

13. The managing system according to claim 10 , wherein the controller is configured to:

scan the WPON for changes in at least one of AP configuration or CPE configuration; and

trigger the configuring of the AP to CPE association when at least one of an AP is added from the WPON, an AP is removed from the WPON, a CPE is added from the WPON, and or a CPE is removed from the WPON.

14. The managing system according to claim 10 , wherein the controller is configured to periodically configure the AP to CPE association.

15. A non-transitory computer-readable medium storing instructions, which when executed by a computer, cause the computer to perform the method of claim 1 .
