Problems solved by technology

[0004] However, the above method of using SC-PTM to send MBMS services can only be realized in each cell under one base station, and there is no corresponding protocol to support the area range across base stations, so this method cannot be used between different base stations to send MBMS services, resulting in the failure of simulcast between cells of different base stations, so that users cannot obtain diversity gain

Abstract

The present invention provides a SC-PTM-based simulcast method and device, the method comprising: a cell / multicast coordination entity MCE establishes a connection with each base station; the MCE configures SC-PTM simulcast for each cell corresponding to the base station Resource pool; the MCE sends the list information of the SC-PTM simulcast resource pool to each of the base stations; the list information includes a cell identifier, a service type, and the identifier of the SC-PTM simulcast resource pool corresponding relationship, and is used to instruct each base station to perform resource scheduling for the services of each cell according to the list information, so that cells corresponding to different base stations can also use SC-PTM to send MBMS services, realizing cross-base station SC‑PTM simulcast between cells ensures that users can obtain diversity gain.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a SC-PTM-based simulcast method and device. Background technique [0002] Multimedia Broadcast / Multicast Service (Multimedia Broadcast Multicast Service, referred to as MBMS) is an important feature introduced by the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) in the R6 version. A point-to-multipoint service in which multiple users transmit data simultaneously. [0003] In a long term evolution (Long Term Evolution, LTE for short) system, the MBMS service is usually sent in a Single Cell Point To Multipoint (Single Cell Point To Mulipoints, SC-PTM for short) manner. In the SC-PTM method, the simulcast area, simulcast subframe, and simulcast bandwidth are introduced in the downlink. In order to enable users to obtain diversity gain, each cell in the entire simulcast area is within the simulcast bandwidth of a ...
