Method and apparatus for notifying a subframe configuration of multicast broadcast single frequency network

摘要

The present invention provides a method for notifying Multicast Broadcast Single Frequency Network (MBSFN) subframe configuration, which comprises the following steps: a first node sends its MBSFN subframe configuration, via an X2 interface, to a second node with which the first node is connected; the first node receives the MBSFN subframe configuration of the second node as a feedback. According to the invention, a serving cell can obtain the MBSFN subframe configurations of the neighboring cells and/or RNs, so that rational utilization of resources is achieved according to the configurations. Therefore, interference between cells is reduced, and system capacity and efficiency are improved.

1. A method for notifying Multicast Broadcast Single Frequency Network (MBSFN) subframe configuration, comprising:
a first node sending its MBSFN subframe configuration, via an X2 interface, to a plurality of second nodes to which the first node is connected, wherein the MBSFN subframe configuration of the first node includes X2 configuration update messages of the first node if the MBSFN subframe configuration of the first node changes; if the first node receives the MBSFN subframe configurations of the respective second nodes as feedback; the first node compares the MBSFN subframe configurations of the respective second nodes with the MBSFN subframe configuration of the first node, and sets system information or a radio resource control (RRC) connection reconfiguration information according to the comparison result, wherein the system information or the RRC connection reconfiguration information includes a first bit sequence, and the first bit sequence is set based on the outcome of the comparison result; and if the first node does not receive the feedback MBSFN subframe configurations of the respective second nodes, the first node sets the system information or the RRC connection reconfiguration information according to a second bit sequence different than the first bit sequence.
