Method and device division multiplexing service time

A method for transmitting a service, comprising: receiving a specific service sent in subframes specific, wherein the specific service is a service broadcast multimedia multicast or unicast service, or one or more than one type of service broadcast mode broadcast or multicast, being specific subframes selected from specific radio frames, with the specific radio frames selected in a unit of time, where the time unit comprises 2M radio frames containing each of the radio frames a number of R subframes to be assigned to transmit the service, where R is a natural number and M is a nonnegative integer; and receive position information of specific radio frames; and characterized in that the time unit comprises 2M radio frames, each of which contains R subframes that can be assigned to specific service, where R is a natural number and where M is a nonnegative integer; wherein the position information of specific radio frames is an interval of the specific radio frames whose range of specific radio frames in the time unit is 2m, 0 <= m <= M.
