Wherein, main Serving cell is user terminal access, and the community of fail safe input and NAS (Non Access Stratum, Non-Access Stratum) mobility information can be provided.
The scheme of the embodiment of the present invention can be applied under a plurality of scenes, such as carrier activation scene, multicarrier handoff scenario etc.
If be applied in carrier activation scene, main Serving cell, user terminal place is the main Serving cell of the current access of user terminal;
Accordingly, carrier aggregation subdistrict is can carry out the community of carrier aggregation transmission with the main Serving cell of the current access of user terminal.
If be applied in multicarrier handoff scenario, main Serving cell, user terminal place is the main Serving cell of access before user terminal switches or the main Serving cell of switching rear access;
Accordingly, carrier aggregation subdistrict is the community that after can switching with user terminal, carrier aggregation transmission can be carried out in the main Serving cell of access.
MIB, SIB1 and SIB2 that community is corresponding comprise multiple systems information, but are not that every kind of system information is all relevant to carrier aggregation transmission.
The embodiment of the present invention will be transmitted relevant system information as polymerization transmission information to carrier aggregation; The set that the information of using when carrier aggregation is transmitted in system information corresponding to community forms is as the set of polymerization transmission information.
Further, to polymerization transmission information, set is divided, and is divided into the first polymerization transmission information and the second polymerization transmission information.
Wherein, the first polymerization transmission information be the information content of polymerization transmission information corresponding to any Liang Ge community when changing, the information content before and after changing is identical polymerization transmission information all, and not identical polymerization transmission informations.That is to say, the polymerization transmission information that minizone must be identical and minizone affirm that different polymerization transmission informations is as the first polymerization transmission information.
Minizone must be identical polymerization transmission information comprise but be not limited to one or more in following message: SFN (SystemFrameNumber, System Frame Number), TDD configuration.

Preferably, user terminal for different conditions, the second polymerization transmission information also can be different, such as T300 connects process of establishing for RRC, and for the user terminal in connection status, can not initiate again RRC (Radio Resource Control, radio resource control) and connect process of establishing, therefore for can not comprising T300 in the second polymerization transmission information corresponding to the user terminal in connection status.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As shown in Figure 2, the system of embodiment of the present invention transmitting system information comprises: network equipment 10 and user terminal 20.
Network equipment 10, for the polymerization transmission information set corresponding from each carrier aggregation subdistrict, determine that in the polymerization transmission information set corresponding with main Serving cell, user terminal place, information type is identical, and the polymerization transmission information that the information content is different, send definite polymerization transmission information, wherein the set of polymerization transmission information is the set that in system information corresponding to carrier aggregation subdistrict, the information of use forms when carrier aggregation is transmitted.
User terminal 20, for receiving the polymerization transmission information from network equipment 10.
Owing to there being a plurality of polymerization transmission informations in the set of polymerization transmission information, 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 from main Serving cell, the polymerization transmission information identical with main Serving cell do not need to send, and can further pare down expenses like this;
Accordingly, user terminal 20 is after receiving polymerization transmission information, polymerization transmission information using the polymerization transmission information of receiving as corresponding carrier aggregation subdistrict, for the polymerization transmission information of not receiving, the polymerization transmission information using the polymerization transmission information of main Serving cell as carrier aggregation subdistrict.
Such as: there are carrier aggregation subdistrict A, B and C, wherein carrier aggregation subdistrict A is main Serving cell, and the downlink bandwidth of carrier aggregation subdistrict B is identical with main Serving cell, the maximum transmission power of carrier aggregation subdistrict C is identical with main Serving cell, network equipment 10 does not just send the downlink bandwidth that carrier aggregation subdistrict B is corresponding, and does not send the maximum transmission power that carrier aggregation subdistrict C is corresponding; The discovery that user terminal 20 is received does not have downlink bandwidth and maximum transmission power corresponding to carrier aggregation subdistrict C that carrier aggregation subdistrict B is corresponding, user terminal 20 is just known the downlink bandwidth using the downlink bandwidth of main Serving cell as carrier aggregation subdistrict B, the maximum transmission power using the maximum transmission power of main Serving cell as carrier aggregation subdistrict C.
Introduce the set of polymerization transmission information above and comprised the first polymerization transmission information and the second polymerization transmission information, network equipment 10 need to be determined the first not identical polymerization transmission information of the information content that changes front and back in the first polymerization transmission information corresponding to each carrier aggregation subdistrict, and determine in the second polymerization transmission information corresponding to current each carrier aggregation subdistrict, the information type of the second polymerization transmission information corresponding with current main Serving cell is identical, and the second polymerization transmission information that the information content is different, using the first polymerization transmission information of determining and the second polymerization transmission information as definite polymerization transmission information.
Due to the information content before and after changing in the first polymerization transmission information not identical the first polymerization transmission information be each minizone different polymerization transmission information certainly, so this part polymerization transmission information must send; And the second polymerization transmission information just likely has the information type of the second polymerization transmission information corresponding with current main Serving cell identical, and the second different polymerization transmission information of the information content.The information type of the second polymerization transmission information that certainly also may be not corresponding with current main Serving cell is identical, and the second different polymerization transmission information of the information content.
For the second polymerization transmission information, can adopt the mode informing user terminal 20 of increment (delta) signaling,, when polymerization transmission information is identical, informing user terminal 20 polymerization transmission informations, only do not notify indication information; When polymerization transmission information is different, informing user terminal 20 polymerization transmission informations.
Concrete, if there is the information type of the second polymerization transmission information corresponding with current main Serving cell identical, and the second different polymerization transmission information of the information content, the second polymerization transmission information that network equipment 10 transmissions are determined just can; If the information type of the second not corresponding with current main Serving cell polymerization transmission information is identical, and the second polymerization transmission information that the information content is different, network equipment 10 need to be using the first indication information as the second polymerization transmission information of determining, and wherein the first indication information is used to indicate the second polymerization transmission information second polymerization transmission information corresponding as carrier aggregation subdistrict that user terminal is corresponding using main Serving cell.Accordingly, user terminal 20 after receiving the first indication information, the second polymerization transmission information that will be using the second polymerization transmission information of main Serving cell as carrier aggregation subdistrict.
The first indication information can be 1bit data, such as being 0, can be also one group of special bit, such as 01010101.......(the second indication information～four indication information and the first indication information introduced are below similar, if different indication informations adopts same numeral, can distinguish by different dedicated signalings, also can distinguish by the zones of different at same dedicated signaling.)
In specific implementation process, network equipment 10 can be placed in a dedicated signaling by the first polymerization transmission information and the second polymerization transmission information and send, and also can be placed in two dedicated signalings and send.
If application scenarios is carrier activation scene, dedicated signaling can be:
RRC connects reallocation message, and carrier aggregation activates message etc.
If application scenarios is multicarrier handoff scenario, dedicated signaling can be:
RRC connects reallocation message, switching command etc.
Wherein, the second polymerization transmission information can also comprise cell-level the second polymerization transmission information and user class the second polymerization transmission information, cell-level the second polymerization transmission information is effective in Yi Ge community, be applied to the configuration information of community itself, include but not limited to one or more in following message:
Cell downlink bandwidth (dl-Bandwidth) in MIB, PHICH configuration.UE uplink transmit power restriction (P-max) in SIB1, place, community frequency band (freqBandIndicator).Radio Resource common configuration (radioResourceConfigCommon) in SIB2, the upstream frequency (ul-CarrierFreq) in frequency information (freqInfo), upstream bandwidth (ul-Bandwidth) and additional frequency diffusion (additionalSpectrumEmission).
User class the second polymerization transmission information is effective in Yi Ge community, is applied to the configuration information of all users in community, includes but not limited to one or more in following message:
UE timer and constant (ue-TimersAndConstants comprises T300, T301, T310, T311, N310, N311 etc.), timing advance timer (TimeAlignmentTimer).
Network equipment 10 can send cell-level the second polymerization transmission information, user class the second polymerization transmission information and the first polymerization transmission information to user terminal by least one dedicated signaling.Such as network equipment 10 can send by three dedicated signalings, (a dedicated signaling carries cell-level the second polymerization transmission information, a dedicated signaling carrying user class second polymerization transmission information, a dedicated signaling carries the first polymerization transmission information); Also can send by two dedicated signalings (a dedicated signaling carries the first polymerization transmission information, another dedicated signaling carrying cell-level the second polymerization transmission information and user class second polymerization transmission information); Can also send by a dedicated signaling.
In specific implementation process, if determined in cell-level the second polymerization transmission information corresponding to each carrier aggregation subdistrict, the information type of not corresponding with main Serving cell cell-level the second polymerization transmission information is identical, and cell-level the second polymerization transmission information that the information content is different, network equipment 10 can be using the second indication information as definite cell-level the second polymerization transmission information, wherein the second indication information is used to indicate cell-level the second polymerization transmission information cell-level second polymerization transmission information corresponding as carrier aggregation subdistrict that user terminal is corresponding using main Serving cell,
If determined in user class the second polymerization transmission information corresponding to each carrier aggregation subdistrict, the information type of not corresponding with main Serving cell user class the second polymerization transmission information is identical, and user class the second polymerization transmission information that the information content is different, network equipment 10 can be using the 3rd indication information as definite user class the second polymerization transmission information, and wherein the 3rd indication information is used to indicate user class the second polymerization transmission information user class second polymerization transmission information corresponding as carrier aggregation subdistrict that user terminal is corresponding using main Serving cell.
The mode that sends user class the 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 subdistrict from carrier aggregation subdistrict, and user class the second polymerization transmission information corresponding to the carrier aggregation subdistrict of selection sent to user terminal, user class the second polymerization transmission information that wherein sends to user terminal is that the information type of the user class second polymerization transmission information corresponding with main Serving cell, user terminal place is identical, and different user class the second polymerization transmission information of the information content;
Accordingly, user terminal 20, according to the user class second polymerization transmission information of at least one carrier aggregation subdistrict of receiving, is determined user class the second polymerization transmission information corresponding to all carrier aggregation subdistricts that carries out carrier aggregation transmission.
Under this mode, network equipment 10 is identical in the information type of having determined the user class second polymerization transmission information corresponding with main Serving cell, user terminal place, and after different user class the second polymerization transmission information of the information content, can only send the user class second polymerization transmission information of a carrier aggregation subdistrict of determining; Also can send the user class second polymerization transmission information of definite a plurality of carrier aggregation subdistricts; Can also send the user class second polymerization transmission information (this situation is identical with transmission cell-level the second polymerization transmission information) of definite whole carrier aggregation subdistricts.
The user class second polymerization transmission information of concrete network equipment 10 transmission which or which carrier aggregation subdistricts, can according to community self-characteristic, be determined by network equipment 10 or user terminal 10, also can be definite by holding consultation between network equipment 10 and user terminal 20.
Such as determining according to community self-characteristic, depend primarily on the channel transfer characteristic of the corresponding member carrier in community, suppose that two the member carrier characteristics of channel corresponding to carrier aggregation subdistrict differ larger, timer (T310) sum counter (N310 that user can not use identical Radio Link Failure to detect, N311) member carrier of Dui Zheliangge community carries out wireless link channel quality-monitoring, timer (T310) sum counter (N310 that the Radio Link Failure of Zhe Liangge community detects so, N311) just need to all send to user, otherwise, select one of them to send to user.
If user class the second polymerization transmission information that network equipment 10 transmitting portion carrier aggregation subdistricts are corresponding, network equipment 10 can informing user terminal in the 20 partial carrier wave aggregation cell that send which carrier aggregation subdistrict identical with the user class second polymerization transmission information of which carrier aggregation subdistrict of remainder.Such as having four carrier aggregation subdistrict A, B, C and D, wherein user class the second polymerization transmission information of carrier aggregation subdistrict A and carrier aggregation subdistrict B is identical, 10 of network equipments need to send user class the second polymerization transmission information of carrier aggregation subdistrict A, C and D, then informing user terminal 20 carrier aggregation subdistrict A are identical with B, and user terminal 20 is received user class the second polymerization transmission information of just knowing carrier aggregation subdistrict B after user class the second polymerization transmission information of carrier aggregation subdistrict A.
If network equipment 10 sends user class the second polymerization transmission information corresponding to whole carrier aggregation subdistricts, user terminal 20 is received just user class the second polymerization transmission information using the user class of receiving the second polymerization transmission information as corresponding carrier aggregation subdistrict.
In specific implementation process, network equipment 10 and user terminal 20 can be distinguished according to the zones of different of dedicated signaling the user class second polymerization transmission information (such as the user class second polymerization transmission information of Yi Shi carrier aggregation subdistrict, region one, the rest may be inferred for the user class second polymerization transmission information of Er Shi carrier aggregation subdistrict, region two) of carrier aggregation subdistrict; Can also before user class the second polymerization transmission information, be added by network equipment 10 that can to distinguish be the sign of which carrier aggregation subdistrict, sign of appointing such as cell ID or network equipment 10 and user terminal 20 etc.
Mode two, network equipment 10 is in carrier aggregation subdistrict respective user level the second polymerization transmission information, there is the information type of the user class second polymerization transmission information corresponding with main Serving cell, user terminal place identical, and during different user class the second polymerization transmission information of the information content, the 4th indication information is sent to user terminal as user class the second polymerization transmission information, wherein the 4th indication information is used to indicate user terminal using the user class second polymerization transmission information of definite carrier aggregation subdistrict of the last time as current user class the second polymerization transmission information.
Under this mode, network equipment 10 is identical in the information type of having determined the user class second polymerization transmission information corresponding with main Serving cell, user terminal place, and after different user class the second polymerization transmission information of the information content, the 4th indication information is sent to user terminal as user class the second polymerization transmission information; Accordingly, user terminal 20 is after receiving the 4th indication information, just know using the user class second polymerization transmission information of definite carrier aggregation subdistrict of the last time as current user class the second polymerization transmission information, do not change the user class second polymerization transmission information of existing each carrier aggregation subdistrict.
For user class the second polymerization transmission information, can also comprise the user class second polymerization transmission information of common configuration and/or the user class second polymerization transmission information of specialized configuration.
The user class second polymerization transmission information of common configuration is effective in Yi Ge community, is applied to the configuration information of all users in community, includes but not limited to one or more in following message:

As shown in Figure 5, the method for embodiment of the present invention transmitting system information comprises the following steps:
Step 501, network side are from polymerization transmission information set corresponding to each carrier aggregation subdistrict, determine that in the polymerization transmission information set corresponding with main Serving cell, user terminal place, information type is identical, and the polymerization transmission information that the information content is different, wherein the set of polymerization transmission information is the set that in system information corresponding to carrier aggregation subdistrict, the information of use forms when carrier aggregation is transmitted.
Step 502, network side send definite polymerization transmission information to user terminal.
Wherein, after step 502, can further include:
Step 503, user terminal are determined the polymerization transmission information of carrier aggregation subdistrict according to the polymerization transmission information of receiving.
Owing to there being a plurality of polymerization transmission informations in the set of polymerization transmission information, user terminal is known each polymerization transmission information of main Serving cell, so it is just passable that network side only need to send the polymerization transmission information different from main Serving cell, the polymerization transmission information identical with main Serving cell do not need to send, and can further pare down expenses like this;
Accordingly, in step 503, user terminal is after receiving polymerization transmission information, polymerization transmission information using the polymerization transmission information of receiving as corresponding carrier aggregation subdistrict, for the polymerization transmission information of not receiving, the polymerization transmission information using the polymerization transmission information of main Serving cell as carrier aggregation subdistrict.
Such as: there are carrier aggregation subdistrict A, B and C, wherein carrier aggregation subdistrict A is main Serving cell, and the downlink bandwidth of carrier aggregation subdistrict B is identical with main Serving cell, the maximum transmission power of carrier aggregation subdistrict C is identical with main Serving cell, network equipment 10 does not just send the downlink bandwidth that carrier aggregation subdistrict B is corresponding, and does not send the maximum transmission power that carrier aggregation subdistrict C is corresponding; The discovery that user terminal 20 is received does not have downlink bandwidth and maximum transmission power corresponding to carrier aggregation subdistrict C that carrier aggregation subdistrict B is corresponding, user terminal 20 is just known the downlink bandwidth using the downlink bandwidth of main Serving cell as carrier aggregation subdistrict B, the maximum transmission power using the maximum transmission power of main Serving cell as carrier aggregation subdistrict C.
Introduce the set of polymerization transmission information above and comprised the first polymerization transmission information and the second polymerization transmission information, in step 501, network side need to be determined the first not identical polymerization transmission information of the information content that changes front and back in the first polymerization transmission information corresponding to each carrier aggregation subdistrict, and determine in the second polymerization transmission information corresponding to current each carrier aggregation subdistrict, the information type of the second polymerization transmission information corresponding with current main Serving cell is identical, and the second polymerization transmission information that the information content is different, using the first polymerization transmission information of determining and the second polymerization transmission information as definite polymerization transmission information.
Due to the information content before and after changing in the first polymerization transmission information not identical the first polymerization transmission information be each minizone different polymerization transmission information certainly, so this part polymerization transmission information must send; And the second polymerization transmission information just likely has the information type of the second polymerization transmission information corresponding with current main Serving cell identical, and the second different polymerization transmission information of the information content.The information type of the second polymerization transmission information that certainly also may be not corresponding with current main Serving cell is identical, and the second different polymerization transmission information of the information content.
For the second polymerization transmission information, can adopt the mode informing user terminal of increment signaling,, when polymerization transmission information is identical, informing user terminal polymerization transmission information, does not only notify indication information; When polymerization transmission information is different, informing user terminal polymerization transmission information.
Concrete, if there is the information type of the second polymerization transmission information corresponding with current main Serving cell identical, and the second different polymerization transmission information of the information content,, in step 502, network side sends the second polymerization transmission information of determining and just can; If the information type of the second not corresponding with current main Serving cell polymerization transmission information is identical, and the second polymerization transmission information that the information content is different, in step 502, network side need to be using the first indication information as the second polymerization transmission information of determining, and wherein the first indication information is used to indicate the second polymerization transmission information second polymerization transmission information corresponding as carrier aggregation subdistrict that user terminal is corresponding using main Serving cell.Accordingly, in step 503 user terminal after receiving the first indication information, the second polymerization transmission information that will be using the second polymerization transmission information of main Serving cell as carrier aggregation subdistrict.
The first indication information can be 1bit data, such as being 0, can be also one group of special bit, such as 01010101.......(the second indication information～four indication information and the first indication information introduced are below similar, if different indication informations adopts same numeral, can distinguish by different dedicated signalings, also can distinguish by the zones of different at same dedicated signaling.)
In step 502, network side can be placed in a dedicated signaling by the first polymerization transmission information and the second polymerization transmission information and send, and also can be placed in two dedicated signalings and send.
Wherein, the second polymerization transmission information can also comprise cell-level the second polymerization transmission information and user class the second polymerization transmission information.
In step 502, network side can send cell-level the second polymerization transmission information, user class the second polymerization transmission information and the first polymerization transmission information to user terminal by least one dedicated signaling.Such as network side can send by three dedicated signalings (a dedicated signaling carries cell-level the second polymerization transmission information, and a dedicated signaling carries user class the second polymerization transmission information, and a dedicated signaling carries the first polymerization transmission information); Also can send by two dedicated signalings (a dedicated signaling carries the first polymerization transmission information, another dedicated signaling carrying cell-level the second polymerization transmission information and user class second polymerization transmission information); Can also send by a dedicated signaling.
In step 501, if determined in cell-level the second polymerization transmission information corresponding to each carrier aggregation subdistrict, the information type of not corresponding with main Serving cell cell-level the second polymerization transmission information is identical, and cell-level the second polymerization transmission information that the information content is different, network side can be using the second indication information as definite cell-level the second polymerization transmission information, and wherein the second indication information is used to indicate cell-level the second polymerization transmission information cell-level second polymerization transmission information corresponding as carrier aggregation subdistrict that user terminal is corresponding using main Serving cell;
If determined in user class the second polymerization transmission information corresponding to each carrier aggregation subdistrict, the information type of not corresponding with main Serving cell user class the second polymerization transmission information is identical, and user class the second polymerization transmission information that the information content is different, network side can be using the 3rd indication information as definite user class the second polymerization transmission information, and wherein the 3rd indication information is used to indicate user class the second polymerization transmission information user class second polymerization transmission information corresponding as carrier aggregation subdistrict that user terminal is corresponding using main Serving cell.
In step 502, the mode that sends user class the 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 subdistrict from carrier aggregation subdistrict, and user class the second polymerization transmission information corresponding to the carrier aggregation subdistrict of selection sent to user terminal, user class the second polymerization transmission information that wherein sends to user terminal is that the information type of the user class second polymerization transmission information corresponding with main Serving cell, user terminal place is identical, and different user class the second polymerization transmission information of the information content;
Accordingly, in step 503, user terminal, according to the user class second polymerization transmission information of at least one carrier aggregation subdistrict of receiving, is determined user class the second polymerization transmission information corresponding to all carrier aggregation subdistricts that carries out carrier aggregation transmission.
Under this mode, network side is identical in the information type of having determined the user class second polymerization transmission information corresponding with main Serving cell, user terminal place, and after different user class the second polymerization transmission information of the information content, can only send the user class second polymerization transmission information of a carrier aggregation subdistrict of determining; Also can send the user class second polymerization transmission information of definite a plurality of carrier aggregation subdistricts; Can also send the user class second polymerization transmission information (this situation is identical with transmission cell-level the second polymerization transmission information) of definite whole carrier aggregation subdistricts.
Concrete network side sends the user class second polymerization transmission information of which or which carrier aggregation subdistrict, can according to community self-characteristic, be determined by network side or user terminal, also can be definite by holding consultation between network side and user terminal.
If user class the second polymerization transmission information that network side transmitting portion carrier aggregation subdistrict is corresponding, in the partial carrier wave aggregation cell that network side can informing user terminal sends, which carrier aggregation subdistrict is identical with the user class second polymerization transmission information of which carrier aggregation subdistrict of remainder.Such as having four carrier aggregation subdistrict A, B, C and D, wherein user class the second polymerization transmission information of carrier aggregation subdistrict A and carrier aggregation subdistrict B is identical, network side only need to send user class the second polymerization transmission information of carrier aggregation subdistrict A, C and D, then informing user terminal carrier aggregation subdistrict A is identical with B, and user terminal is received user class the second polymerization transmission information of just knowing carrier aggregation subdistrict B after user class the second polymerization transmission information of carrier aggregation subdistrict A.
If network side sends user class corresponding to whole carrier aggregation subdistricts the second polymerization transmission information, user terminal is received just user class the second polymerization transmission information using the user class of receiving the second polymerization transmission information as corresponding carrier aggregation subdistrict.
In specific implementation process, network side and user terminal can be distinguished according to the zones of different of dedicated signaling the user class second polymerization transmission information (such as the user class second polymerization transmission information of Yi Shi carrier aggregation subdistrict, region one, the rest may be inferred for the user class second polymerization transmission information of Er Shi carrier aggregation subdistrict, region two) of carrier aggregation subdistrict; Can also before user class the second polymerization transmission information, be added by network side that can to distinguish be the sign of which carrier aggregation subdistrict, sign of appointing such as cell ID or network side and user terminal etc.
Mode two, network side are in carrier aggregation subdistrict respective user level the second polymerization transmission information, there is the information type of the user class second polymerization transmission information corresponding with main Serving cell, user terminal place identical, and during different user class the second polymerization transmission information of the information content, the 4th indication information is sent to user terminal as user class the second polymerization transmission information, and wherein the 4th indication information is used to indicate user terminal using the user class second polymerization transmission information of definite carrier aggregation subdistrict of the last time as current user class the second polymerization transmission information.
Under this mode, network side is identical in the information type of having determined the user class second polymerization transmission information corresponding with main Serving cell, user terminal place, and after different user class the second polymerization transmission information of the information content, the 4th indication information is sent to user terminal as user class the second polymerization transmission information; Accordingly, in step 503, user terminal is after receiving the 4th indication information, just know using the user class second polymerization transmission information of definite carrier aggregation subdistrict of the last time as current user class the second polymerization transmission information, do not change the user class second polymerization transmission information of existing each carrier aggregation subdistrict.
For user class the second polymerization transmission information, can also comprise the user class second polymerization transmission information of common configuration and/or the user class second polymerization transmission information of specialized configuration.
Network side is being determined while only needing user terminal to upgrade user class the second polymerization transmission information, is being sent the user class second polymerization transmission information of specialized configuration to this user terminal; When determining that each user terminal needing in community upgrades user class the second polymerization transmission information, each user terminal in Xiang Gai community sends the user class second polymerization transmission information of common configuration.
User terminal, after receiving the user class second polymerization transmission information of specialized configuration, is replaced the user class of the specialized configuration of receiving the second polymerization transmission information the user class second polymerization transmission information of the common configuration that paid-in type is identical.
The method of embodiment of the present invention transmitting system information also can be used as several steps of carrying out in carrier aggregation transmission, such as being the preparation process of carrier aggregation transmission, after step 503, can be the step of carrying out carrier aggregation transmission before step 501.Certainly, the sequential relationship between these steps can change as required.
With the scheme of the embodiment of the present invention, be applied under carrier activation scene and be elaborated below.
As shown in Figure 6, in embodiment of the present invention carrier activation scene schematic diagram, suppose that UE initialization is in community 1, because traffic carrying capacity increases, UE need to carry out CA transmission (being carrier aggregation transmission), base station 1 determines to allow this UE aggregation cell 1 and community 2 carry out CA transmission, and then base station sends to UE by dedicated signaling by the necessary system information of the CA of community 2.
The downlink working frequency of community 2 is f2, certainly different from the f1 of community 1, and base station must send it to UE, and UE is according to this information, and CA transmission is carried out in f2Shang community 2.
If the downlink bandwidth of community 2 is identical with community 1, base station does not send it to UE, and UE now thinks that the downlink bandwidth of Liang Ge community is identical, carries out accordingly CA transmission; If the downlink bandwidth of community 2 is different from community 1, base station sends it to UE, and UE carries out CA transmission according to this bandwidth.
If the PHICH of community 2 configuration is different from community 1, base station sends it to UE, and UE carries out CA transmission according to this PHICH configuration.
For UE-TimersAndConstants, T300 connects process of establishing for RRC, and T301 and T311 are for RRC connection reconstruction process, and T310, N310 and N311 are all for Radio Link Failure process.Because UE is at present in connection status, therefore, can not initiate again RRC and connect process of establishing, the T300 of community 2 does not need to send to UE.Because RRC connection reconstruction process is based on single community, therefore, T301 and T311 preserve a set of at UE end.For T310, N310 and N311, can configure to UE by dedicated signaling.If UE is current does not have T310, N310 and a N311 of dedicated signaling configuration, when T310, the N310 of community 2 and community 1 is identical with N311, do not send to UE so, UE thinks the identical of community 2 and community 1; When if T310, the N310 of community 2 and community 1 are different with N311, 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 detection to all CC) according to the detailed process of T310, N310 and N311 and Radio Link Failure detection.
Specifically, if Radio Link Failure process based on the separately judgement of each member carrier, UE is used different parameters to different communities, and safeguards respectively; If Radio Link Failure process is based on the unified judgement of all member carriers, UE can only be used set of parameter, and this cover parameter can be that network shows configuration by signaling, can be also that UE and network are made an appointment.
For TimeAlignmentTimer, be mainly used for (the maintenance uplink synchronous) of random access procedure, base station can configure to UE by dedicated signaling, and base station can, according to the characteristic of community 1 and community 2, configure same or different TimeAlignmentTimer to the two.If when the TimeAlignmentTimer of the TimeAlignmentTimer of community 2 and community 1 is identical, do not send to UE, UE thinks the identical of 2 Yu communities 1, community; If when the TimeAlignmentTimer of the TimeAlignmentTimer of community 2 and community 1 is different, the TimeAlignmentTimer of community 2 is sent to UE, UE carries out subsequent operation according to the detailed process of TimeAlignmentTimer and random access.
Specifically, if Radio Link Failure process based on the separately judgement of each member carrier/member carrier group, UE is used different parameters to different community/cell set, and safeguards respectively; If Radio Link Failure process is based on the unified judgement of all member carrier/member carrier groups, UE can only be used a TimeAlignmentTimer, and this parameter can be that network shows configuration by signaling, can be also that UE and network are made an appointment.
