Abstract
A method for multiplexing a broadcast service channel and a non-broadcast service channel includes: reserving TF resources for carrying non-broadcast service data on a sub-frame for carrying broadcast service data and multiplexing the broadcast service data and the non-broadcast service data to the sub-frame for carrying the broadcast service data. Correspondingly a device for multiplexing a broadcast service channel and a non-broadcast service channel is disclosed. Hence the system signaling overhead occupied during a TDM process between broadcast service and Unicast service is reduced and the transmission delay of Unicast service is reduced.
