Problems solved by technology

In practical applications, since the network side is not clear about the ability of the UE to support the configuration of the number of downlink carriers in frequency band I and frequency band VIII in this frequency band combination, the UE is configured with 4 downlink carriers at the same time when the network resources are sufficient. At this time, it is impossible to determine the number of downlink carriers configured in frequency band I and the number of downlink carriers configured in frequency band VIII. If the UE is configured with one carrier in frequency band I and three carriers in frequency band VIII at this time, although the

Example Embodiment

[0089] Example 1

[0090] figure 1 It is a schematic flow chart of the method for transmitting the UE's ability to support dual-band multi-carrier in Embodiment 1 of the present invention, such as figure 1 As shown, in this embodiment, when the UE supports dual-band multi-carrier, the sub-cell Max Multi cell support on each Band is added to the cell radio access capability in the RRCConnection Setup Complete message sent to the RNC, which means that The index of the maximum number of downlink carriers that can be configured on each frequency band. The protocol description is shown in Table 1. The value rule of the newly added Max Multi cell support on each Band in this embodiment is as follows:

[0091] When the UE supports Band I and Band VIII, Band Combination is set to 1, BandA in Table 2 is Band I at this time, and BandB in Table 2 is Band VIII at this time;

[0092] When the UE supports Band II and Band IV, Band Combination is set to 2, Band A in Table 2 is Band II at this time,...

[0103] figure 2 It is a schematic flow chart of the method for transmitting the UE's ability to support dual-band multi-carrier in Embodiment 2 of the present invention, such as figure 2 As shown, in this embodiment, when the UE supports dual-band multi-carrier, Max Multi cell support on each Band is added to the cell radio access capability, and the UE supports dual-band configuration multi-carrier capability, which is different from Embodiment 1. Yes, in the second embodiment, the UE CapabilityInformation message informs the RNC that the UE supports the dual-band configuration multi-carrier capability, that is, if the UE supports multi-carrier capability and dual-band, the UE includes Max Multi cell in the UE Capability Information message sent to the RNC The specific instructions for support on each Band are the same as in Embodiment 1, and will not be repeated here.

[0104] Example 3

[0105] image 3 This is a schematic flow chart of the method for transmitting the UE's ability to support dual-band multi-carrier in Embodiment 3 of the present invention, such as image 3 As shown, in this embodiment, when the UE supports dual-band multi-carrier, the sub-cell Radio Access Capability Multi Cell Band Combination List and Multi Cell are added to the cell radio access capability carried in the RRCConnection Setup Complete message sent to the RNC. The meaning of SupportBand Combination and Radio Access Capability Multi Cell Band Combination List is the total number of downlink carrier combinations that can be configured on two frequency bands in all frequency band combinations supported by the UE. The meaning of Multi Cell Support Band Combination is that each combination is supported on each frequency band. The configured downlink carrier number combination index, and its protocol description is shown in Table 5. The application examples of the ne...

Abstract

The invention discloses a method for a transmission terminal to support double-frequency-band multicarrier capacity; when the terminal UE (user equipment) supports the double-frequency-band multicarrier, the UE enables the supported frequency-band combined information and the capacity of all frequency bands in supporting the configuration of downlink carrier number to be carried in an interactive message of a radio network controller (RNC) to be transmitted to the RNC. The invention also discloses a system for the transmission terminal to support double-frequency-band multicarrier capacity correspondingly. As the RNC can obtain the frequency-band combination supported by the UE and the number of respective supported and configured downlink carriers of two frequency bands in each frequency-band combination after analyzing the interactive message from the UE, so as to provide reference for resource distribution, the method and the system are beneficial to reasonable resource distribution of network side and improve the network resource utilization rate.

Description

technical field [0001] The invention relates to multi-carrier technology in network communication, in particular to a method and system for a transmission terminal supporting dual-band multi-carrier capability. Background technique [0002] In the R8 stage, dual-carrier (DC) was introduced. The terminal (UE) does not support MIMO and DC dual-carrier at the same time, and the two downlink HS carriers must be in the same frequency band; in the R9 stage, the UE can support the downlink two Carriers are separately configured in two different frequency bands (DB-DC-HSDPA); now four downlink carriers are introduced, although this can greatly improve the downlink transmission rate, but currently, for UEs that support downlink multi-carrier configuration in two frequency bands , the network side cannot accurately know the number of downlink carriers supported by the UE on each of the two supported frequency bands, and thus cannot accurately and reasonably utilize network resources a...
