Abstract
Methods and systems are provided for use with wireless networks having one or more cell in which each cell includes a base station (BS) at least one relay station (RS) and at least one mobile station (MS). The at least one relay station can be used as an intermediate station for providing communication between the BS and MS. Methods are provided for an RS to initially access the network access of the RS by MSs initially accessing the network methods of allocating OFDM resources for communicating between the BS RS and/or MS for example dividing transmission resources into uplink and downlink transmissions and methods of inserting pilot symbols into transmission resources used by the RS. In some embodiments on the invention the methods are consistent and/or can be used in conjunction with existing standards such as 802.16e.

16. The method of claim 5, further comprising performing interference cancellation techniques to improve detection performance.
17. The method of claim 15, wherein performing interference cancellation techniques is performed by one or both of the RS and the BS.
18. A method for inserting OFDM (orthogonal frequency division multiplexed) pilot symbols in a time-frequency resource in a system using relay stations (RSs), at least one RS having N transmitting antennas, where N>=1, comprising:
inserting pilot symbols in time and frequency for each of the N transmitting antennas in a given relay station in symbol locations that are not assigned to pilot symbols used by a base station (BS) serving a cell in which the given RS is currently located or mobile stations (MSs) located in the cell served by the BS; and
transmitting from a first MS to one of the BS and the given RS using a first sub-channel, wherein an antenna configuration of the first MS includes multiple antennas; and
