PHYSICAL LAYER (PHY) DESIGN FOR A LOW LATENCY MILLIMETER WAVE (MMW) BACKHAUL SYSTEM
First Claim
1. A method for use in a base station for establishing a low latency millimeter wave (mmW) backhaul connection, the method comprising:
- receiving a mmW relay schedule from an evolved Node B (eNB) within one Long Term Evolution (LTE) scheduling interval;
decoding the mmW relay schedule;
steering a receive beam and a transmit beam according to the mmW relay schedule;
receiving a data packet from a second base station in a mmW transmission time interval (TTI) based on the mmW relay schedule using the receive beam; and
transmitting the data packet to a third base station based on the mmW relay schedule using the transmit beam, wherein the transmitting begins before reception of the data packet is complete.

Abstract
A method and apparatus are disclosed for establishing a low latency millimeter wave (mmW) backhaul connection. A base station may receive a mmW relay schedule from an evolved Node B (eNB) within one Long Term Evolution (LTE) scheduling interval. The base station may decode the mmW relay schedule, and initialize a mmW radio transmission resource according to the mmW relay schedule. The base station may receive a data packet from a second base station in a mmW transmission time interval (TTI) based on the mmW relay schedule using the initialized mmW radio transmission resource, and may transmit the data packet to a third base station based on the mmW relay schedule using the initialized mmW radio transmission resource. The transmitting may begin before the reception of the data packet is complete.
