Abstract

A transmission method of multiple services combination is as follow. During service initialization of both communication sides, an identical TFCS (Transport Format Combination Set), containing all TFC (Transport Format Combination), is created in both sides. When a data is transmitted according to specific TFC at the transmitting end, a corresponding TFCI (Transport Format Combination Indicator) of the TFC is transmitted simultaneously. At the receiving end, the TFCI is used to look for the TFC in the TFCS. The TFCS is divided into no less than one sub-sets according to the specific channel characteristics of the service. TFCI is only used for looking for TFC in a sub-set, but not used to indicate the sub-set where the TFC is located. When data of services are transmitted with TFC at the transmitting end, the service specific channel characteristics are used to define a sub-set where the TFC is located at the receiving end, and the TFCI is used to look for the TFC in the sub-set.

Claims

1. A transmission method of multiple services combination, comprising:

during services initialization of communication, creating an identical transport format combination set (TFCS) which contains all transport format combination (TFC) at both transmitting end and receiving end;

dividing the TFCS into no less than one sub-sets according to specific channel characteristics of services, and using transport format combination indicator (TFCI) to indicate TFC in a sub-set where the TFC is located;

transmitting services according to the specific TFC in the sub-set, and transmitting the corresponding TFCI of the TFC simultaneously;

defining the sub-set where the TFC is located according the services specific channel characteristics of this time, looking for the TFC in the sub-set by TFCI, and receiving services according to the found TFC.

2. The transmission method according to claim 1, wherein TFCI transmission mode of every sub-set is identical or different, which is bits mode, and/or code mode, and/or physical time-slot mapping mode.

3. The transmission method according to claim 2, further comprising:

defining corresponding TFCI transmission mode according to specific channel characteristics of the services.

4. The transmission method according to claim 1, wherein the different sub-sets of TFCS have overlap part or have not overlap part.

5. The transmission method according to claim 1, wherein the specific channel characteristics of services that are used to divide TFCS into no less than one sub-set and the specific channel characteristics of services that are used to define a sub-set where the TFC is located at receiving end, are identical or different, but they essentially define to a same sub-set.

6. The transmission method according to claim 1, wherein the specific channel characteristics of services, which are used to divide said TFCS into no less than one sub-set, are number of time-slots, and/or number of channels, and/or spreading factor, and/or data transmission rate.

7. The transmission method according to claim 1, wherein the specific channel characteristics of services, which are used to define a sub-set where the TFC is located at the receiving end, are number of time-slots, and/or number of channels, and/or spreading factor, and/or data transmission rate.
