Method and device for service time division multiplexing

A method for transmitting a service by a base station, wherein a time unit is divided into a plurality of Type 1 subunits, a Type 1 subunit is divided into a plurality of Type 2 subunits, and so on, that a Type n subunit is divided into a plurality of Type n +1 subunits, where 1≦n≦N and N is a nonnegative integer, the method comprising:

• selecting at least one Type 1 subunit as a specific Type 1 subunit for carrying the service, selecting at least one Type 2 subunit in the selected specific Type 1 subunit as a specific Type 2 subunit for carrying the service, and so on, that at least one Type n+1 subunit is selected in a specific Type n subunit as a specific Type n+1 subunit for carrying the service;
• and
• sending position information of the Type 1 to Type n+1 specific subunits, wherein the position information of the Type 1 to Type n+1 specific subunits is represented, at each level, by a bitmap or a number or an interval of the specific subunit in the specific subunit of the level above;
• when the number of the specific Type N′ subunit in the time unit is more than or equal to a threshold, determining a value n0, where 1≦N′≦N, 1≦n0≦N, n0 has at least one value, which represents that all of the Type n0 subunits in a specific Type n0−1 subunit are specific Type n0 subunits, and the position information of the specific Type n0 subunits is not sent;
• and
• when the number of the specific Type N′ subunit in the time unit is less than the threshold, determining a value of n0′, where 1≦n0′≦N, n0 ′ has at least one value, which represents that dividing directly the Type n0′−1 subunit into at least one Type n0′+1 subunit, and the position information of the specific Type n0′ subunit is not sent.

A method for transmitting service, comprising:

• selecting a part or all of the radio frames in one time unit as specific radio frames;
• selecting a part or all of subframes in the specific radio frames as specific subframes for sending a specific service;
• sending the service according to the selecting steps;
• and
• sending position information of the specific radio frames and/or position information of the specific subframes;
• wherein the time unit comprises several radio frames, each of which contains R subframes that can be allocated to the specific service, where R is a natural number,
• wherein the position information of the specific radio frames or the position information of the specific subframes are/is transmitted on broadcast channels,
• wherein the position information of the specific radio frames is transmitted on any one of a primary broadcast channel, a secondary broadcast channel or a dynamic broadcast channel, and the position information of the specific subframes is transmitted on any one of the primary broadcast channel, the secondary broadcast channel or the dynamic broadcast channel.
