Example Embodiment

[0066] figure 2 Describes the technical solution process of the present invention, including:

[0067] 1.1 Fully arrange the TFS of all transmission channels to obtain the TFCS, as shown in 101 in the figure;

[0068] 1.2 Determine whether the number of TFCs in the complete set exceeds the number that the UE can support, as shown in the figure 102; if yes, go to the next step; if not, output the current TFCS as the result, as shown in the figure 105;

[0069] 1.3 Obtain the smallest TTI value in the transmission channel with non-OTF in the current TFCS, as shown in the figure 103;

[0070] 1.4 Select a TFC with a non-zero TF corresponding to the TTI value from the current TFCS and delete it, as shown in the figure 104; then, go to step 1.2.

[0071] image 3 It is a flowchart of an embodiment of the present invention. Such as image 3 Shown:

[0072] 1. Fully arrange the TFS of all transmission channels to obtain the complete set of TFCS;

Abstract

The present invention relates to the transmission format combination set (TFCS) configuration method of distributing transmission to UE in WCDMA system. The present invention first obtains TFCS set via completely arranging all the transmission channels and then deletes or decreases the set in case that the TFC amount in the set exceeds that the UE can support. Each time, one TFC is deleted, which is ensured to be not one part of 'TTI restriction' of any other TFC. The present invention makes it possible to obtain optimal TFCS configuration, which can meet the limitation in maximum TFC number of TTI restriction and UE radio access capacity and has maximum TFC number, resulting in maximum possibility of obtaining highest transmission efficiency.

Description

technical field [0001] The present invention relates to the field of WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) communication, and specifically relates to assigning a transmission channel to a UE (User Equipment, user equipment) in a WCDMA system related to TFCS (Transport Format Combination Set , method for transport format combination sets). Background technique [0002] In a WCDMA system, communication between a UTRAN (Universal Terrestrial Radio Access Network, Universal Terrestrial Radio Access Network) and a UE is performed on a transport channel, and the transport channel is finally mapped to a physical channel. A UE may have multiple transmission channels at the same time. For a transmission channel, the data bits transmitted thereon are transmission blocks or transmission block sets arriving at a period of a Transmission Timing Interval (TTI, Transmission Timing Interval). [0003] A transport format (TF, Transport Forma...
