If network side sends user class second polymerization transmission information of whole carrier aggregation sub-district correspondence, then user terminal is just received user class second polymerization transmission information of receiving is transmitted information as user class second polymerization of corresponding carrier aggregation sub-district.
In specific implementation process, network side and user terminal can be distinguished user class second polymerization transmission information (such as zone one is user class second polymerization transmission information of carrier aggregation sub-district one, and zone two is that the rest may be inferred for user class second polymerization transmission information of carrier aggregation sub-district two) of carrier aggregation sub-district according to the zones of different of dedicated signaling; Can also before the user class second polymerization transmission information, add that can to distinguish be the sign of which carrier aggregation sub-district by network side, sign of appointing such as cell ID or network side and user terminal etc.
Mode two, network side are in the carrier aggregation sub-district respective user level second polymerization transmission information, have identical with the information type of corresponding user class second polymerization of user terminal place master's Serving cell transmission information, and when information is transmitted in user class second polymerization that the information content is different, the 4th indication information is sent to user terminal as user class second polymerization transmission information, and wherein the 4th indication information is used for user class second polymerization transmission information of the indicating user terminal carrier aggregation sub-district that the last time is definite as current user class second polymerization transmission information.
Under this mode, network side is determining that the information type with corresponding user class second polymerization of user terminal place master's Serving cell transmission information is identical, and after the different user class second polymerization transmission information of the information content, the 4th indication information is sent to user terminal as user class second polymerization transmission information; Accordingly, in the step 503, user terminal is after receiving the 4th indication information, user class second polymerization transmission information of just knowing the carrier aggregation sub-district that the last time is determined does not promptly change user class second polymerization transmission information of existing each carrier aggregation sub-district as current user class second polymerization transmission information.
For user class second polymerization transmission information, can also comprise user class second polymerization transmission information of common configuration and/or user class second polymerization transmission information of specialized configuration.
Network side sends user class second polymerization transmission information of specialized configuration to this user terminal when determining only to need user terminal to upgrade user class second polymerization transmission information; When need to determine each user terminal in the sub-district to upgrade user class second polymerization transmission information, each user terminal in this sub-district sends user class second polymerization transmission information of common configuration.
User terminal is replaced the user class second polymerization transmission information of the specialized configuration received user class second polymerization transmission information of the identical common configuration of paid-in type after the user class second polymerization transmission information of receiving specialized configuration.
The method of embodiment of the invention transmitting system information also can be used as the several steps that carries out in the carrier aggregation transmission, such as the preparation process that can be the carrier aggregation transmission, can be the step of carrying out the carrier aggregation transmission after the step 503 before the step 501.Certainly, the sequential relationship between these steps can change as required.
Be applied under the carrier wave activation scenario with the scheme of the embodiment of the invention below and be elaborated.
As shown in Figure 6, in the embodiment of the invention carrier wave activation scenario schematic diagram, suppose that the UE initialization is in sub-district 1, because traffic carrying capacity increases, UE need carry out CA transmission (being the carrier aggregation transmission), base station 1 decision allows this UE aggregation cell 1 and sub-district 2 carry out the CA transmission, and the base station sends to UE by dedicated signaling with the necessary system information of CA of sub-district 2 then.
The downlink working frequency of sub-district 2 is f2, and is different certainly with the f1 of sub-district 1, and then the base station must send it to UE, and UE is according to this information, and the CA transmission is carried out in the sub-district 2 on f2.
If the downlink bandwidth of sub-district 2 is identical with sub-district 1, then the base station does not send it to UE, and UE thinks that at this moment the downlink bandwidth of two sub-districts is identical, carries out the CA transmission in view of the above; If the downlink bandwidth of sub-district 2 is different with sub-district 1, then the base station sends it to UE, and UE carries out the CA transmission according to this bandwidth.
If the PHICH of sub-district 2 configuration is different with sub-district 1, then the base station sends it to UE, and UE is according to this PHICH configuration carrying out CA transmission.
For UE-TimersAndConstants, T300 is used for the RRC connection to set up process, and T301 and T311 are used for RRC connection reconstruction process, and T310, N310 and N311 all are used for the Radio Link Failure process.Because UE has been in connection status at present, therefore, can not initiate the RRC connection again and set up process, the T300 of sub-district 2 does not need to send to UE.Because RRC connection reconstruction process is based on single sub-district, therefore, T301 and T311 preserve a cover at the UE end and get final product.For T310, N310 and N311, can dispose to UE by dedicated signaling.If UE is current not to have T310, N310 and a N311 of dedicated signaling configuration, when T310, the N310 of sub-district 2 and sub-district 1 is identical with N311, do not send to UE so, UE thinks the identical of sub-district 2 and sub-district 1; If T310, the N310 of sub-district 2 and sub-district 1 and N311 are not simultaneously, T310, N310 and N311 are sent to UE, UE carries out subsequent operation (in the process of CA transmission, can carry out Radio Link Failure to all CC and detect) according to the detailed process of T310, N310 and N311 and Radio Link Failure detection.
Specifically, if the Radio Link Failure process is based on the independent judgement of each member carrier, then UE uses different parameters to different sub-districts, and safeguards respectively; If the Radio Link Failure process is based on the unified judgement of all member carriers, UE can only use set of parameter, and this cover parameter can be that network passes through the signaling configurations shown, also can be that UE and network are made an appointment.
For TimeAlignmentTimer, mainly be (the maintenance uplink synchronous) that is used for random access procedure, the base station can dispose to UE by dedicated signaling, and the base station can dispose same or different TimeAlignmentTimer to the two according to the characteristic of sub-district 1 and sub-district 2.If when the TimeAlignmentTimer of the TimeAlignmentTimer of sub-district 2 and sub-district 1 is identical, do not send to UE, identical with sub-district 1 that UE thinks sub-district 2; If the TimeAlignmentTimer of the TimeAlignmentTimer of sub-district 2 and sub-district 1 is not simultaneously, the TimeAlignmentTimer of sub-district 2 is sent to UE, UE carries out subsequent operation according to TimeAlignmentTimer and the detailed process that inserts at random.
Specifically, if the Radio Link Failure process is based on the independent judgement of each member carrier/member carrier group, then UE uses different parameters to different sub-districts/cell set, and safeguards respectively; If the Radio Link Failure process is based on the unified judgement of all member carriers/member carrier group, UE can only use a TimeAlignmentTimer, and this parameter can be that network passes through the signaling configurations shown, also can be that UE and network are made an appointment.
