Title:
BANDWIDTH ALLOCATION REQUEST IN CELLULAR MESH NETWORKS
Document Type and Number:
WIPO Patent Application WO/2020/162701
Kind Code:
A1
Abstract:
A base station (BS) in a wireless communication network for bandwidth allocation requests (BARs) and method of operating the BS. The method includes receiving an uplink (UL) BAR for an amount of UL resources for transmission of UL data to the BS and determining, based at least in part on the UL BAR, an amount of backhaul resources for transmission of backhaul data from the BS to a parent BS of the BS via a wireless backhaul connection. The method further includes receiving the UL data; transmitting, to the parent BS at least before reception of the UL data is complete, a first BAR indicating the determined amount of the backhaul resources; and transmitting the received UL data to the parent BS via the wireless backhaul connection based on the first BAR.
