Apparatus and method for providing relay backhaul communications in a wireless communication system

摘要

An apparatus and method for designing a relay backhaul channel in a wireless communication system are provided. At least one relay node utilized for communication with respective user devices and at least one relay backhaul channel for conducting in-band half-duplex communication with the at least one relay node are identified. The relay backhaul channel may be an FDM channel, a TDM/FDM channel, or a joint R-PDCCH/R-PDSCH channel. The relay channel is used for communicating with the at least one relay node. The supportable ranks of the R-PDSCH channel may depend on the number of resources reserved for demodulation reference signals in the R-PDCCH region.

1. A method for facilitating relay backhaul communication in a wireless communication system using at least one relay node, the method comprising:
identifying at least one relay node utilized for communication with respective user devices; identifying at least one relay backhaul control channel for conducting communication with the at least one relay node, wherein the at least one relay backhaul control channel comprises a control portion of a first set of resource blocks (RBs); identifying, in the control portion of the first set of RBs, a first set of resources providing reference signals configured for demodulation of the at least one relay backhaul control channel; identifying, in the control portion of the first set of RBs, a second set of resources providing reference signals configured for demodulation of at least one relay backhaul data channel, the second set of resources including at least the first set of resources; and communicating with the at least one relay node using the at least one relay backhaul control channel.
