Problems solved by technology

The RNC configures the UE on the secondary carrier, and there is no corresponding Fast Physical Access Channel (FPACH, Fast Physical Access Channel) on the secondary carrier. Therefore, after the UE sends the Sync UL code on the secondary carrier, it cannot fail to obtain the NodeB Response, which will inevitably lead to uplink synchronization failure
[0012] 2. When the UE is handed over from other cells to this cell, if the main carrier resources in this cell are insufficient and the secondary carrier has resources, it will easily lead to congestion of the main carrier, which greatly weakens the advantages of multiple carrier frequencies
[0013] When the UE is handed over from other cells to this cell, UEs that do not support multiple carrier frequencies cannot be configured on the secondary carrier. , As

Embodiment Construction

[0051] The channel resource allocation method of the present invention is applied in the TD-SCDMA multi-carrier system, and its core is to allow the use of the auxiliary carrier time slot TS0 on the auxiliary carrier frequency, that is, to allow the beamforming channel to be allocated to the auxiliary carrier time slot TS0. For example, allocating the DPCH channel of the UE to the auxiliary carrier time slot TS0 can further improve the capacity of the multi-carrier system.

[0052] The channels that can be allocated on the time slot TS0 in the present invention include downlink DPCH channel, FPACH, etc., which will be described below.

[0053] refer to figure 1 , which is a flowchart of allocating DPCH channels of user equipment in the present invention. It mainly includes the following steps:

[0054] First at step 10, judge whether the system allows the DPCH channel to be allocated to the secondary carrier, if so, proceed to step 11; otherwise perform step 12;

Abstract

This invention discloses a channel resource allocation method in TDM-CDMA multi carrier system, which comprises following steps mainly: a. deciding whether the being allotted channel is shaped-beam channel, if yes, executing step b; or else, executing step c; b. allotting the shaped-beam channel to main carrier time slot, auxiliary carrier time slot or other time slots; c. allotting the channel to main carrier time slot or other time slot in auxiliary carrier. The invention can solve the problem that auxiliary carrier capacity reduces by TSO.

Description

technical field [0001] The present invention relates to code division multiple access communication technology, more specifically, the present invention relates to a kind of channel resource allocation method in Time Division-Synchronization Code Division Multiple Access (TD-SCDMA, Time Division-Synchronization Code Division Multiple Access) multi-carrier system. Background technique [0002] At present, mobile communication has been developed to the third generation of mobile communication (3G, Third Generation). TD-SCDMA is one of the three main standards of the third generation mobile communication approved by the International Telecommunication Union (ITU, International Telecommunication Union) in May 2000 and by 3GPP in March 2001. As a 3G standard of time-division multiplexing, TD-SCDMA is regarded as a time-division multiplexing technical solution with a low chip rate (1.28MCps, 1.28 megachips / second) in the ITU standard. [0003] Like other mobile communication syst...
