METHOD AND DEVICE FOR RELAY NODE ACCESS

摘要

The present invention provides a method and device for relay node (RN) access, wherein the method includes the following steps: a base station sends a downlink message to a RN to trigger the RN to switch from listening in a physical downlink control channel (PDCCH) to listening in a RN-dedicated physical downlink control channel (R-PDCCH); and said RN acquires time-frequency resources of the R-PDCCH from said base station, before or while receiving said downlink message. The present invention enables a RN to switch from transmitting according to indications on a PDCCH to transmitting according to indications on a R-PDCCH, that is, the RN switches from being in a connection state as a terminal to being in a connection state as a RN. The present invention makes less change to existing flows, offering advantages of easy implementation, flexible configuration, etc.
