Wherein, main Serving cell is that user terminal inserts, and the sub-district of fail safe input and NAS (Non Access Stratum, Non-Access Stratum) mobility information can be provided.

The scheme of the embodiment of the invention can be applied under a plurality of scenes, such as carrier wave activation scenario, multicarrier handoff scenario etc.

If be applied in the carrier wave activation scenario, user terminal place master's Serving cell is the main Serving cell of the current access of user terminal;

Accordingly, the carrier aggregation sub-district is the sub-district that can carry out the carrier aggregation transmission with the main Serving cell of the current access of user terminal.

If be applied in the multicarrier handoff scenario, user terminal place master's Serving cell is the main Serving cell that inserts before user terminal switches or switches the main Serving cell that the back is inserted;

Accordingly, the carrier aggregation sub-district is to switch the sub-district that the main Serving cell that inserts the back can carry out the carrier aggregation transmission with user terminal.

Comprise multiple systems information among the MIB of sub-district correspondence, SIB1 and the SIB2, but be not that every kind of system information is all relevant with the carrier aggregation transmission.

The embodiment of the invention is transmitted information with the system information relevant with the carrier aggregation transmission as polymerization; The set that the information of using when carrier aggregation is transmitted in the system information of sub-district correspondence is formed is transmitted ensemble of communication as polymerization.

Further, polymerization transmission ensemble of communication is divided, be divided into first polymerization transmission information and second polymerization transmission information.

Wherein, the first polymerization transmission information be the information content of polymerization transmission information of any two sub-district correspondences when changing, the polymerization transmission information that the information content before and after changing is all identical, and polymerization all inequality transmission information.That is to say that the polymerization transmission information that the polymerization transmission information that the minizone must be identical is different certainly with the minizone is transmitted information as first polymerization.

The minizone must identical polymerization transport packet be drawn together but is not limited in the following message one or more: SFN (SystemFrameNumber, System Frame Number), TDD configuration.

Minizone certainly different polymerization transport packet is drawn together but is not limited in the following message one or more: cell downlink working frequency points (dl-freq), ECGI (E-UTRAN Cell Global ID, cellular global identity).

The second polymerization transmission information is the polymerization transmission information except that the first polymerization transmission information in the polymerization transmission ensemble of communication.That is to say, the second polymerization transmission information is that intercarrier may be identical, also may be different polymerization transmission information, the information content of the polymerization transmission information of promptly any two sub-district correspondences is when changing, difference after the identical change before changing is identical behind different the variation before perhaps changing.

Intercarrier may be identical, also may be different the polymerization transport packet draw together but be not limited in the following message one or more:

Preferable, user terminal at different conditions, second polymerization transmission information also can be different, such as T300 is to be used for RRC to connect the process of setting up, and for the user terminal that is in connection status, can not initiate RRC (Radio Resource Control, radio resource control) again and connect the process of setting up, therefore can not comprise T300 in the second polymerization transmission information for the user terminal correspondence that is in connection status.

Below in conjunction with Figure of description the embodiment of the invention is described in further detail.

As shown in Figure 2, the system of embodiment of the invention transmitting system information comprises: network equipment 10 and user terminal 20.

Network equipment 10, be used for polymerization transmission ensemble of communication from each carrier aggregation sub-district correspondence, determine identical with information type in the corresponding polymerization transmission ensemble of communication of user terminal place master's Serving cell, and the polymerization transmission information that the information content is different, the polymerization transmission information that transmission is determined, wherein the set of the information composition that uses in the system information that ensemble of communication is a carrier aggregation sub-district correspondence is transmitted in polymerization when carrier aggregation is transmitted.

User terminal 20 is used to receive the polymerization transmission information from network equipment 10.

Because a plurality of polymerization transmission information are arranged in the polymerization transmission ensemble of communication, user terminal 20 is known each polymerization transmission information of main Serving cell, so it is just passable that 10 of network equipments need to send the polymerization transmission information different with main Serving cell, the polymerization transmission information identical with main Serving cell does not need to send, and can further pare down expenses like this;

Accordingly, user terminal 20 is after receiving polymerization transmission information, the polymerization transmission information of receiving is transmitted information as the polymerization of corresponding carrier aggregation sub-district,, the polymerization transmission information of main Serving cell is transmitted information as the polymerization of carrier aggregation sub-district for the polymerization transmission information of not receiving.

Such as: carrier aggregation sub-district A, B and C are arranged, wherein carrier aggregation sub-district A is main Serving cell, and the downlink bandwidth of carrier aggregation sub-district B is identical with main Serving cell, the maximum transmission power of carrier aggregation sub-district C is identical with main Serving cell, then network equipment 10 does not just send the downlink bandwidth of carrier aggregation sub-district B correspondence, and the maximum transmission power that does not send carrier aggregation sub-district C correspondence; The discovery that user terminal 20 is received does not have the downlink bandwidth of carrier aggregation sub-district B correspondence and the maximum transmission power of carrier aggregation sub-district C correspondence, then user terminal 20 is just known the downlink bandwidth of the main Serving cell downlink bandwidth as carrier aggregation sub-district B, with the maximum transmission power of the main Serving cell maximum transmission power as carrier aggregation sub-district C.

Introduce polymerization transmission ensemble of communication above and comprised first polymerization transmission information and second polymerization transmission information, the information content first polymerization transmission information all inequality before and after then network equipment 10 needs to determine to change in the first polymerization transmission information of each carrier aggregation sub-district correspondence, and determine in the second polymerization transmission information of current each carrier aggregation sub-district correspondence, identical with the information type of corresponding second polymerization of current main Serving cell transmission information, and second polymerization transmission information that the information content is different is transmitted information as the polymerization transmission information of determining with first polymerization transmission information and second polymerization determined.

Because being the different certainly polymerization in each minizone, the information content first polymerization transmission information all inequality before and after changing in the first polymerization transmission information transmits information, so this part polymerization transmission information must send; And that second polymerization transmission information just might have is identical with the information type of corresponding second polymerization transmission information of current main Serving cell, and information is transmitted in the second different polymerization of the information content.Certainly may be not identical with the information type of corresponding second polymerization transmission information of current main Serving cell yet, and different second polymerization transmission information of the information content.

Can adopt increment (delta) means of signaling informing user terminal 20 for second polymerization transmission information, promptly when polymerization transmission information was identical, informing user terminal 20 polymerizations transmission information was not only notified indication information; Transmit information not simultaneously when polymerization, information is transmitted in informing user terminal 20 polymerizations.

Concrete, if having identical with the information type of corresponding second polymerization transmission information of current main Serving cell, and different second polymerization transmission information of the information content, then network equipment 10 sends second polymerization transmission information of determining and just can; If the information type with corresponding second polymerization transmission information of current main Serving cell is not identical, and second polymerization transmission information that the information content is different, then network equipment 10 need be with first indication information as second polymerization transmission information of determining, wherein first indication information is used for indicating user terminal with second polymerization transmission information of main Serving cell correspondence, second polymerization transmission information as carrier aggregation sub-district correspondence.Accordingly, user terminal 20 will transmit information as second polymerization of carrier aggregation sub-district with second polymerization transmission information of main Serving cell after receiving first indication information.

First indication information can be the 1bit data, such as being 0, also can be one group of special bit, such as 01010101.......(second indication information of introducing below～the 4th indication information and first indication information are similar, if different indication informations adopts same numeral, then can distinguish, also can distinguish by zones of different at same dedicated signaling by different dedicated signalings.)

In specific implementation process, network equipment 10 can place a dedicated signaling to send first polymerization transmission information and the second polymerization transmission information, also can place two dedicated signalings to send.

If application scenarios is the carrier wave activation scenario, then dedicated signaling can be:

RRC connects reallocation message, and carrier aggregation activates message etc.

If application scenarios is the multicarrier handoff scenario, then dedicated signaling can be:

RRC connects reallocation message, switching command etc.

Wherein, second polymerization transmission information can also comprise cell-level second polymerization transmission information and user class second polymerization transmission information, the cell-level second polymerization transmission information is effective in a sub-district, be applied to the configuration information of sub-district itself, include but not limited in the following message one or more:

In specific implementation process, if determine in each carrier aggregation sub-district corresponding district level second polymerization transmission information, the information type with main Serving cell corresponding district level second polymerization transmission information is not identical, and cell-level second polymerization transmission information that the information content is different, network equipment 10 can be with second indication information as cell-level second polymerization transmission information of determining, wherein second indication information be used for indicating user terminal with main Serving cell corresponding district level second polymerization transmission information as carrier aggregation sub-district corresponding district level second polymerization transmission information;

If determine in the user class second polymerization transmission information of each carrier aggregation sub-district correspondence, the information type with corresponding user class second polymerization transmission information of main Serving cell is not identical, and user class second polymerization transmission information that the information content is different, network equipment 10 can be with the 3rd indication information as user class second polymerization transmission information of determining, wherein the 3rd indication information is used for indicating user terminal with user class second polymerization transmission information of main Serving cell correspondence user class second polymerization transmission information as carrier aggregation sub-district correspondence.

The mode that sends user classes second polymerization transmission information for network equipment 10 has a variety of, enumerates several below:

Mode one, network equipment 10 are selected at least one carrier aggregation sub-district from the carrier aggregation sub-district, and the user class second polymerization transmission information of the carrier aggregation sub-district correspondence selected sent to user terminal, the user class second polymerization transmission information that wherein sends to user terminal is identical with the information type of corresponding user class second polymerization of user terminal place master's Serving cell transmission information, and different user class second polymerization transmission information of the information content;

Accordingly, user terminal 20 is according to user class second polymerization transmission information of at least one carrier aggregation sub-district of receiving, determines to carry out user class second polymerization transmission information of all carrier aggregation sub-district correspondences of carrier aggregation transmission.

Under this mode, network equipment 10 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, can only send user class second polymerization transmission information of a carrier aggregation sub-district of determining; Also can send user class second polymerization transmission information of definite a plurality of carrier aggregation sub-district; Can also send user class second polymerization transmission information (this situation is identical with transmission cell-level second polymerization transmission information) of definite whole carrier aggregation sub-district.

Concrete, if having identical with the information type of corresponding second polymerization transmission information of current main Serving cell, and different second polymerization transmission information of the information content, then in the step 502, network side sends second polymerization transmission information of determining and just can; If the information type with corresponding second polymerization transmission information of current main Serving cell is not identical, and second polymerization transmission information that the information content is different, then in the step 502, network side need be with first indication information as second polymerization transmission information of determining, wherein first indication information is used for indicating user terminal with second polymerization transmission information of main Serving cell correspondence, second polymerization transmission information as carrier aggregation sub-district correspondence.Accordingly, user terminal will transmit information as second polymerization of carrier aggregation sub-district with second polymerization transmission information of main Serving cell in the step 503 after receiving first indication information.

In the step 502, network side can place a dedicated signaling to send first polymerization transmission information and the second polymerization transmission information, also can place two dedicated signalings to send.

Wherein, second polymerization transmission information can also comprise cell-level second polymerization transmission information and user class second polymerization transmission information.

In the step 502, network side can send cell-level second polymerization transmission information, user class second polymerization transmission information and first polymerization transmission information to user terminal by at least one dedicated signaling.Can send (i.e. information is transmitted in a dedicated signaling carrying cell-level second polymerization, and a dedicated signaling carries user class second polymerization transmission information, and a dedicated signaling carries first polymerization transmission information) by three dedicated signalings such as network side; Also can send (promptly a dedicated signaling carries first polymerization transmission information, another dedicated signaling carrying cell-level second polymerization transmission information and user class second polymerization transmission information) by two dedicated signalings; Can also send by a dedicated signaling.

In the step 501, if determine in each carrier aggregation sub-district corresponding district level second polymerization transmission information, the information type with main Serving cell corresponding district level second polymerization transmission information is not identical, and cell-level second polymerization transmission information that the information content is different, network side can be with second indication information as cell-level second polymerization transmission information of determining, wherein second indication information be used for indicating user terminal with main Serving cell corresponding district level second polymerization transmission information as carrier aggregation sub-district corresponding district level second polymerization transmission information;

If determine in the user class second polymerization transmission information of each carrier aggregation sub-district correspondence, the information type with corresponding user class second polymerization transmission information of main Serving cell is not identical, and user class second polymerization transmission information that the information content is different, network side can be with the 3rd indication information as user class second polymerization transmission information of determining, wherein the 3rd indication information is used for indicating user terminal with user class second polymerization transmission information of main Serving cell correspondence user class second polymerization transmission information as carrier aggregation sub-district correspondence.

In the step 502, the mode that sends user class second polymerization transmission information for network side has a variety of, enumerates several below:

Mode one, network side are selected at least one carrier aggregation sub-district from the carrier aggregation sub-district, and the user class second polymerization transmission information of the carrier aggregation sub-district correspondence selected sent to user terminal, the user class second polymerization transmission information that wherein sends to user terminal is identical with the information type of corresponding user class second polymerization of user terminal place master's Serving cell transmission information, and different user class second polymerization transmission information of the information content;

Accordingly, user terminal determines to carry out user class second polymerization transmission information of all carrier aggregation sub-district correspondences of carrier aggregation transmission according to user class second polymerization transmission information of at least one carrier aggregation sub-district of receiving in the step 503.

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, can only send user class second polymerization transmission information of a carrier aggregation sub-district of determining; Also can send user class second polymerization transmission information of definite a plurality of carrier aggregation sub-district; Can also send user class second polymerization transmission information (this situation is identical with transmission cell-level second polymerization transmission information) of definite whole carrier aggregation sub-district.

Concrete network side sends user class second polymerization transmission information of which or which carrier aggregation sub-district, can be determined according to the sub-district self-characteristic by network side or user terminal, also can be definite by holding consultation between network side and the user terminal.

If user class second polymerization of network side sending part sub-carrier aggregation cell correspondence transmission information, then in the part carrier aggregation sub-district that can informing user terminal sends of network side which carrier aggregation sub-district and user class second polymerization of which carrier aggregation sub-district of remainder to transmit information identical.Such as four carrier aggregation sub-district A, B, C and D are arranged, wherein user class second polymerization of carrier aggregation sub-district A and carrier aggregation sub-district B transmission information is identical, then network side only need send user class second polymerization transmission information of carrier aggregation sub-district A, C and D, informing user terminal carrier aggregation sub-district A is identical with B then, and then user terminal is received user class second polymerization transmission information of just knowing carrier aggregation sub-district B after the user class second polymerization transmission information of carrier aggregation sub-district A.

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.

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.
