Abstract

The invention discloses a method and a device for increasing the MBMS capacity. The method includes: S101, configuring a dedicated subframe for sending synchronization signals and / or measurement signals in the wireless subframe; the dedicated subframe is one of the following: unicast subframe, MBSFN subframe including unicast part frame and an MBSFN subframe with a preconfigured synchronization signal sequence; S102, sending a downlink synchronization signal or channel on the dedicated subframe according to preconfigured configuration information. The method and device in the present invention realize the transmission of synchronization signals and / or measurement signals in the MBSFN scene by improving the configuration of the frame structure, thereby effectively solving the downlink synchronization and measurement problems in the MBSFN scene, thereby improving the capacity of the MBMS system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for increasing MBMS capacity. Background technique [0002] Multicast / Multicast Single Frequency Network (MBSFN, Multicast-Broadcast Single Frequency Network) requires simultaneous reception of identical waveforms sent from multiple cells, and UE (User Equipment, user terminal) receivers can view multiple MBSFN cells as for a large community. In addition, the UE will not only suffer from inter-cell interference transmitted by adjacent cells, but also benefit from the superposition of signals from multiple MBSFN cells. Not only that, advanced UE receiver technologies such as G-RAKE can also solve the time difference problem of multipath propagation, thereby eliminating intra-cell interference. [0003] MBSFN is divided into two types: MBSFN of dedicated carrier and MBSFN of mixed carrier with unicast (Unicast). At present, the LTE (Long Term Evolution, long...
