Bandwidth allocation request in cellular mesh networks

A base station (BS) in a wireless communication network, the BS comprising:

• a transceiver configured to receive an uplink (UL) bandwidth allocation request (BAR) for an amount of UL resources for transmission of UL data to the BS;
• and
• a processor operably connected to the transceiver, the processor configured to determine, 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,
• wherein the transceiver is further configured to:
• receive the UL data;
• transmit, 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
• transmit the received UL data to the parent BS via the wireless backhaul connection based on the first BAR.
