Abstract:
1. A method for mapping a control channel of a relay link, said method comprising: mapping, by an eNode-B, a control channel of a relay link based on an availability of a control channel through a Frequency Division Multiplex (FDM) mode, a Time Division and Frequency Division Multiplex (TDM-FDM) mode, or a Time Division Multiplex (TDM) mode; transmitting, by the eNode-B, the control channel over the relay link between the eNode-B and a relay node; wherein when the FDM mode is available, the control information of the relay link from the eNode-B to the relay node is carried by one or more resource blocks in the frequency direction and a universal set of Orthogonal Frequency Division Multiplexing (OFDM) symbols in a subframe available to the relay link in the time direction; when the TDM-FDM mode is available, the control information of the relay link from the eNode-B to the relay node is carried by one or more resource blocks in the frequency direction and a subset of OFDM symbols in the subframe available to the relay link in the time direction; when the TDM mode is available, the control information of the relay link from the eNode-B to the relay node is carried by all the resource blocks in the frequency direction and a subset of OFDM symbols in the subframe available to the relay link in the time direction; and the mapping of the control channel comprises mapping in the time direction and/or the frequency direction.
