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 It makes full use of the UE's ability to support 4 carriers, but it does not meet the condition that the maximum number of downlink carriers supported by the UE in frequency band VIII is 2, which will cause the configuration to fail
In addition, if one carrier is configured for this UE in frequency band I and one carrier is configured in frequency band VIII, the configuration at this time meets the support capability of the UE, but obviously does not make full use of network resources and UE capabilities, making the UE's downlink rate Unable to reach the maximum rate it supports, thus unable to make full and reasonable use of network resources

Embodiment 1

[0090] figure 1 It is a schematic flowchart of a method for transmitting UE's dual-band multi-carrier capability in Embodiment 1 of the present invention, as shown in 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 in the cell radio access capability in the RRCConnection Setup Complete message sent to the RNC, which means that in The index of the maximum number of downlink carriers configured on each frequency band is described in Table 1. The value rules for the newly added Max Multi cell support on each Band in this embodiment are as follows:

[0091] When the UE supports frequency band I and frequency band VIII, when the value of Band Combination is 1, BandA in Table 2 is frequency band I at this time, and BandB in Table 2 is frequency band VIII at this time;

[0092] When the UE supports frequency band II and frequency band IV, when the value of Band Combination is 2, Band A in ...

Embodiment 2

[0103] figure 2 It is a schematic flowchart of a method for transmitting UE's dual-band multi-carrier capability in Embodiment 2 of the present invention, as shown in 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 accesscapability, and the UE supports dual-band multi-carrier configuration, which is different from Embodiment 1 Yes, in Embodiment 2, the RNC is notified of the UE's ability to support dual-band configuration and multi-carrier through the UE CapabilityInformation message, that is, if the UE supports multi-carrier capability and dual-band, the UE sends the UE Capability Information message to the RNC. Include Max Multi cell Support on each Band, how to indicate specifically is the same as that in Embodiment 1, and will not be repeated here.

Embodiment 3

[0105] image 3 It is a schematic flowchart of a method for transmitting UE's dual-band multi-carrier capability in Embodiment 3 of the present invention, as shown in image 3 As shown, in this embodiment, when the UE supports dual-band multi-carrier, sub-cells 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, Radio Access Capability Multi Cell Band Combination List is the total number of downlink carrier combinations supported on two frequency bands in all frequency band combinations supported by the UE, and the meaning of Multi Cell Support Band Combination is that each combination is supported on each frequency band The combination index of the configured downlink carrier number, and its protocol description are shown in Table 5. The application example of the new sub-cell Radio AccessCapability Mult...

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...
