Abstract: Method for managing a wireless passive optical network, including a plurality of access points, APs, and a plurality of customer premises equipments, CPEs. The method includes configuring an AP to CPE association based on a load balancing algorithm such that each CPE is associated with at least one AP; configuring for each AP an AP beamforming codebook based on the configured association, wherein the AP beamforming codebook includes entries, wherein each entry is representative for a beam pattern to be transmitted by the AP, and wherein the AP beamforming codebook includes for each CPE associated with the AP—a line of sight, LoS, entry representative for a beam pattern to be transmitted to the respective CPE via a LoS path; and at least one back-up entry representative for a beam pattern to be transmitted to the respective CPE via a back-up path different from the LoS path.

Abstract: Embodiments of the present disclosure relate to device, method, apparatus and computer readable storage medium of power control of spatial reuse for supporting TSC in the unlicensed band. The method comprises in accordance with a determination that a sounding packet is transmitted from a second device, determining CSI of channels between the second device and the third device; determining, at least partially based on the CSI, an applicable transmitting power for a first transmission from the first device to a fourth device during a second transmission for a reception of the feedback of the at least one packet sent from a third device to the second device; and performing the first transmission based on the applicable transmitting power during the second transmission. In this way, a transmission of DL TSC packets that has a time scheduling requirement in contrast with the spatial reuse time window can be achieved. Meanwhile, the harmful interference to NOTSN AP during the Block Acknowledgement reception can be avoid.
