The disclosure claims a method and a device for configuring cell parameters of a Relay Node (RN), which can solve the technical problem that the cell parameters cannot be reasonably configured as a Donor eNB (DeNB) does not know the cell amount of the RN. In the disclosure, the RN sends the cell amount of cells which are managed by the RN to the DeNB via a control signaling, so as to make the DeNB more reasonably configure the cell parameters of the RN. The disclosure solves the problem that the DeNB cannot reasonably allocate resources according to the cell amount of the RN, and avoids resources conflicts, wherein the resources contain an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Cell Global Identifier (ECGI), a Physical Cell ID (PCI) and the like. |

1. A method for configuring cell parameters of a Relay Node, RN, comprising:
sending, by a RN, a control signaling which carries a number representing how many cells that the RN is serving to a Donor eNB, DeNB; and configuring, by the DeNB, cell parameters for the cells that the RN is serving according to the number contained in the control signaling; wherein the cell parameters configured by the DeNB comprise an Evolved Universal Terrestrial Radio Access Network Cell Global Identifier, ECGI, and a Physical Cell ID, PCI; wherein sending, by the RN, the control signaling which carries the number representing how many cells the RN is serving to the DeNB comprises: before the RN establishes a Radio Resource Control, RRC, connection, or re-establishes a RRC connection, or performs a RRC connection reconfiguration, or establishes an S1 connection with the DeNB, sending by the RN the control signaling which carries the number representing how many cells the RN is serving to the DeNB; and when the RN has a RRC connection, or an S1 connection, or an X2 connection with the DeNB, and the number representing how many cells the RN is serving is increased, sending, by the RN, the control signaling which carries the number representing how many cells the RN is serving to the DeNB. |
