1. A method, comprising:
- transmitting first communication signals from a relay node to a base station of a donor macro cell over a wireless backhaul communication link; and
receiving second communication signals by the relay node from one or more mobile stations in the donor macro cell over a radio access link,wherein the base station is allocated a frequency bandwidth for receiving communications from mobile stations, the first communication signals are transmitted over a first portion of the frequency bandwidth and the second communication signals are transmitted over a second portion of the frequency bandwidth, wherein the first and second portions are different portions of the frequency bandwidth.
