Abstract

Base station simulcast controller module apparatuses are adapted to send a message to the base station controller to direct the base station controller to send downlink packets across each of the plurality of base stations for simulcast with a common sector identity (ID). One or more simulcasting control instructions may be sent to the plurality of base stations to facilitate simulcasting with the sector ID from the plurality of base stations. Methods for facilitating simulcasting and de-simulcasting at a plurality of base stations include sending a message to a base station controller to direct the base station controller to send downlink packets across each of a plurality of base stations for simulcast with a common sector identity (ID). One or more simulcasting control instructions are also sent to the plurality of base stations to facilitate simulcasting with the sector ID from the plurality of base stations.
