Abstract
Systems and methods are disclosed for signaling in a point-to-multi-point (PtMP) fixed wireless backhaul network, in which each Hub serves a plurality of Remote Backhaul Modules (RBM). A Hub serves one RBM in each subframe per carrier in TDMA fashion, comprising transmitting a 1 ms TDD frame comprising one DL subframe and one UL subframe and gaps necessary to switch the radio direction and accommodate round trip delay. DL and UL frames may be allocated to different RBMs, with a single RBM in each DL or UL subframe per carrier per antenna beam. Each Hub keeps an independent context for each of its served RBMs. A DL ranging frame carries general information. A UL ranging frame carries a ranging opportunity. RBMs not scheduled in the current timeslot continue to receive a PHY control channel from the serving Hub, and update their parameters or links for link adaptation.
