Abstract
Described method and apparatus for providing the compatibility of backhaul control channel to map, preferentially mapping the frequency that control channel element (CCE) carries out in order to avoid relaying physical control format indicator channel (R-PCFICH), and in order to minimized resource assignment bit map bit, based on the relay resource distribution of tree.Be described herein method and apparatus (the such as via node (RN evolved node B (eNB)) mapping Un down link (DL) control signal, Un DL affirmative acknowledgement (ACK)/negative response (NACK) and/or relaying physical downlink control channel (R-PDCCH) (or similar channel) on the DL direction at eNB to RN (Un interface).This is comprising the process above-mentioned control signal be mapped on time/frequency in RN community in the subframe remaining multicast broadcast multimedia service (MFJMS) Single Frequency Network (MBSFN) and cataloged procedure thereof.In addition, here also describe by avoiding R-PCFICH and the bit of Resourse Distribute being needed reduce to the minimum method and apparatus optimizing signaling consumption.
