Method and apparatus for implementing a space-division-multiplex access method to communicate ( "SDMA") user data and backhaul data with the same wireless time- frequency resources

A method of communicating backhaul data, comprising: Communicating wireless backhaul data between a base station and a central backhaul access point; Communicate wireless user data between the base station and at least one user terminal in a supplied by the base station cell; Assigning a first circumference of time-frequency resources to the wireless user data and the wireless backhaul data, and allocating a second circumference of the time-frequency resources only to the wireless user data and the wireless backhaul data, wherein the same time-frequency resources at least partially encompass the first perimeter for the wireless backhaul data and wireless user data, and include at least a first portion of a data frame at least for wireless backhaul data and wireless user data and a second portion of the data frame for wireless user data OFDM symbols ( "Orthogonal Frequency Division Multiplexing symbols"), the wireless backhaul data and wireless user data via a space-division multiple access method are communicated ( "SDMA"), and the first portion of the data frame, the same time-frequency resources as the second portion of Date Nahmens used, and wherein the first ...
