Abstract
The present disclosure provides a method and device for Relay Node (RN) access, wherein the method comprises the following steps: a base station sends a downlink message to trigger the RN to switch from monitoring a Physical Downlink Control Channel (PDCCH) to monitoring an RN-dedicated Physical Downlink Control Channel (R-PDCCH), and the RN acquires time-frequency resources for an R-PDCCH from the base station, before or while receiving the downlink message. The present disclosure enables an RN to switch from transmitting according to indication on the PDCCH to transmitting according to indication on the R-PDCCH, i.e., the RN switches from being in a connection state as the UE to being in a connection state as an RN. The present disclosure makes less change to the existing flows, offering advantages of easy implementation, flexible configuration, etc.
