METHOD AND SYSTEM FOR DETECTING RELAY PHYSICAL DOWNLINK CONTROL CHANNEL

摘要

The present invention discloses a method for detecting relay physical downlink control channel. The method includes the following steps: the network side divides available resources of relay physical downlink control channel (R-PDCCH) into subsets, and assigns at least one of the subsets to a relay node (RN); the RN determines its R-PDCCH in the assigned subset. The present invention also discloses a system for detecting relay physical downlink control channel, which is applied in the communication network including an RN. The system includes: a division unit, an assignment unit and a determination unit, wherein the division unit and the assignment unit are set at the network side, and the determination unit is set at the RN. The division unit is used for dividing the available resources of R-PDCCH at the network side into subsets; the assignment unit is used for assigning at least one of the subsets to the RN; and the determination unit is used for determining the R-PDCCH of the RN in the assigned subset. The present invention ensures that the relay node can detect the R-PDCCH correctly, reduces the complexity of blindly detecting the physical downlink control channel to a certain extent, and improves the processing efficiency.
