Abstract:
1. A method, comprising: communicating wireless backhaul data between a base station and a central backhaul access point; communicating wireless data between the base station and at least one user terminal within a cell serviced by the base station; allocating a first amount of time-frequency resources for both the wireless data and the wireless backhaul data, and allocating a second amount of the time-frequency resources for only one of the wireless data and the wireless backhaul data, wherein the at least some same time-frequency resources comprise at least part of the first amount; and wherein at least a first portion of a data frame including Orthogonal Frequency-Division Multiplexing (“OFDM”) symbols for at least wireless backhaul data and a second portion of the data frame for the wireless data is communicated via Spatial Division Multiple Access (“SDMA”), and the first portion of the data frame utilizes at least some same time-frequency resources as the second portion of the data frame and wherein the first amount and the second amount of the time-frequency resources are contiguous sets of OFDM symbols.
