Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.

Embodiment 1

Referring to Fig. 1, present embodiment provides a kind of method of forming carrier wave of upgrading, and comprising:

101: receive the CC renewal Indication message that the base station sends, perhaps send CC to terminal and upgrade Indication message, this CC upgrades Indication message and is: CC increases Indication message, CC activation Indication message, CC configuration Indication message or CC and replaces Indication message;

Wherein, CC upgrade Indication message can also for: CC is removed Indication message, CC deexcitation Indication message or CC and separates the configuration Indication message;

102: as CC when to upgrade Indication message be CC increase/activation/configuration Indication message, frequency or C-CI (Cell Specific Component Carrier Indicator according to the CC of increase/activation/configuration, sub-district particular carrier wave identifier) Zhi size, the idle carrier identifiers CI value beginning from current minimum distributes the CI value to the CC of increase/activation/configuration successively;

When CC upgrades Indication message is CC when replacing Indication message, be removed/the CI value of deexcitation/separate the CC of configuration distributes to the CC of increase/activation/configuration; Perhaps, discharge and to be removed/deexcitation/the separate CI value of the CC of configuration, according to the frequency of the CC of increases/activation/configuration or the size of C-CI value, the idle CI value from current minimum begins the value to the CC of increase/activation/configuration distribution CI successively;

Wherein, the CI value is the specific CI value of this terminal.

When CC upgrades Indication message is that CC is removed/deexcitation/when separating the configuration Indication message, discharges to be removed/deexcitation/separate the CI value of the CC of configuration;

Wherein, the expression of "/" in the present embodiment " or ".

The method that present embodiment provides, by according to the frequency of the CC of increase/activation/configuration or the size of C-CI value, successively from the idle CI value of current minimum, CC to described increase/activation/configuration distributes the CI value, the CI value that perhaps will be removed/deexcitation/separate the CC of configuration is distributed to the CC of increase/activation/configuration, perhaps discharge and be removed/deexcitation/the separate CI value of the CC of configuration, according to the frequency of the CC of increase/activation/configuration or the size of C-CI value, idle CI value beginning from current minimum distributes the CI value to the CC of increase/activation/configuration successively, perhaps discharge and be removed/deexcitation/the separate CI value of the CC of configuration, thereby realized CI value at CC reproducting periods reasonable distribution CC, it is chaotic to avoid the CI value to distribute, successfully to realize striding carrier dispatching.

For example, when increase/activation/2 CC of configuration, if the C-CI value of CC1 less than CC2, CC1 then can be distributed to little CI value 001 in and 2 idle CI values 001 of current existence and 010, and big CI value 010 is distributed to CC2; If perhaps the frequency of CC1 is less than CC2, then little CI value 001 can be distributed to CC1, big CI value 010 is distributed to CC2.

It will be appreciated by those skilled in the art that increase/activation/configuration CC process, replace CC process be removed/there is not positive connection in the interprocedual of deexcitation/separate configuration CC, each can constitute an independent embodiment 3 processes.For example, can there be an embodiment, only the CC that increases, activates or dispose be adopted and embodiment one similar processing procedure in this embodiment, and when replacing CC, can adopt method same as the prior art, the method that promptly adopts the CI value to reconfigure fully.Also can when replacing CC, adopt processing method similar to Example 1, and in the method that increases, activates or adopt during configuration CC prior art, i.e. the method that reconfigures fully of CI value.The described method that reconfigures fully is no matter which kind of CC to take place upgrade, and all CC after upgrading are all redistributed the CI value, and present embodiment does not limit.

Embodiment 2

Referring to Fig. 2, present embodiment provides a kind of method of forming carrier wave of upgrading, and concrete steps are as follows:

200: base station and terminal are that the CC of designated state distributes the CI value;

Wherein, designated state is state of activation or configuration status, and configuration status comprises " be configured and be activated " and " being configured but un-activation ".

Wherein, the base station is specifically as follows eNodeB (evolved Node B, evolved base station), and terminal specifically can be UE (User Equipment, a subscriber equipment), and present embodiment does not limit.In addition, the CI value that relates to of this enforcement is the specific CI value of terminal.

Wherein, this step is optional, and present embodiment do not limit the specific implementation method of this step, introduces the implementation method of a kind of step below, referring to Fig. 3.

200a: when terminal RRC initially connect set up finish after, stride carrier dispatching if the base station need start, then the base station sends to terminal and strides the carrier dispatching indication information, the CC that is used for indicating terminal and is designated state distributes the CI value;

Wherein, stride the carrier dispatching indication information and can also carry PDCCH (Physical Downlink ControlChannel, Physical Downlink Control Channel) monitors collection, be used for the PDCCH channel that indicating terminal need be monitored CC, to obtain the schedule information of current all designated state CC.

Wherein, striding the carrier dispatching Indication message can be RRC (Radio Resource Control, Radio Resource control) message, MAC (MediaAccess Control, media interviews control) PDU (Protocol DataUnit, protocol Data Unit) or physical layer signaling send.If RRC message, stride the carrier dispatching Indication message and can be carried at RRC and connect in the reconfiguration message and send.In addition, under the situation about between terminal is carried out the base station, switching, stride the carrier dispatching Indication message and can be carried in the switching command message and send.

200b: after the base station sent and to stride the carrier dispatching Indication message, the base station was according to the frequency of the CC of designated state or the preset order of C-CI value institute foundation (from small to large or from big to small), and the CC that is followed successively by designated state begins to distribute the CI value from designated value;

Wherein, this designated value can be the value of zero or non-zero.In the CC of designated state, there are one or more CI values of not using, perhaps there is not the CI value, the CC that perhaps has the special designated state of static changeless CI value, then when the CC to designated state distributes the CI value not to the CC distribution CI value of these special designated states.If it is 0 that the CC of special designated state has changeless CI value, then designated value can be the value of a non-zero, is not 0 if the CC of this special designated state has changeless CI value, and then designated value can be zero.

200c: terminal receives that the base station sends stride the carrier dispatching Indication message after, terminal is distributed the CI value according to the method identical with the base station, sees step 200b for details, repeats no more here;

Wherein, in the primary distribution process, the preset order of terminal and base station is identical.

200d: optionally, after terminal was finished and striden carrier dispatching preparation, the carrier dispatching acknowledge message was striden in transmission to the base station.

Wherein, striding the carrier dispatching acknowledge message can be RRC message equally, MAC PDU or physical layer signaling.If RRC message, stride the carrier dispatching Indication message and can be carried at RRC and connect in the reconfiguration message and send.In addition, under the situation about between terminal is carried out the base station, switching, stride the carrier dispatching Indication message and can be carried in the switching command message and send.

The assigning process of CI value is as follows during 201:CC increase/activation/configuration, referring to Fig. 4:

201a: the base station sends CC increase/activation/configuration Indication message to terminal;

Wherein, the base station can send CC increase/activation/configuration Indication message to terminal according to factors such as terminal traffic needs or CC variations, thereby for terminal increases new CC, needs to satisfy terminal QoS (Qualityof Service, service quality).

Wherein, CC increase/activation/configuration Indication message can be a RRC message, MAC PDU or physical layer signaling.If RRC message, stride the carrier dispatching Indication message and can be carried at RRC and connect in the reconfiguration message and send.In addition, under the situation about between terminal is carried out the base station, switching, stride the carrier dispatching Indication message and can be carried in the switching command message and send.

201b: the base station is according to the frequency of the CC of increase/activation/configuration or the size of C-CI value, successively from the idle CI value of current minimum, for increase newly/activate/CC that disposes distributes the CI value;

201c: after terminal received CC increase/activation/configuration Indication message, terminal was distributed the CI value according to the method identical with the base station, sees step 201b for details, repeats no more here;

201d: optionally, after terminal is finished the work of increase/activation/configuration, send CC increase/activation/configure-ack message to the base station.

Wherein, CC increase/activation/configure-ack message can be RRC message, MAC PDU or physical layer signaling.If RRC message, stride the carrier dispatching Indication message and can be carried at RRC and connect in the reconfiguration message and send.In addition, under the situation about between terminal is carried out the base station, switching, stride the carrier dispatching Indication message and can be carried in the switching command message and send.

For example, before terminal received CC increase/activation/configuration Indication message that the base station sends, the CC that terminal is being used was CC1, CC3, and CC1 described here and CC3, promptly the C-CI value of the composition carrier wave that takies of terminal is 1 and 3.Simultaneously, from the specific CI value angle of terminal, we can suppose that CC1 and the current specific CI value of terminal of CC3 are respectively 010 and 011, and the operable CI value of terminal free time this moment has so: 000,001,100,101,110,111.Send CC increases/activations/configuration Indication message when the base station to terminal then, during with new CC2 of indicating terminal use and CC4, then terminal should begin to be followed successively by the CC distribution CI value that increases newly according to the size of C-CI value from the CI value of the minimum of current free time.Be that current minimum idle CI value is 000, the CI value of then new composition carrier wave CC2 should be composed with 000, and the CI value of new composition carrier wave CC4 is the next one CI value of free time, and promptly 001.

By above-mentioned example as can be seen, during carrying out CC increase/activation/configuration, realized the reasonable distribution of the CI value of CC, it is chaotic to avoid the CI value to distribute, successfully to realize striding carrier dispatching.

In addition, the base station also can send to terminal at CC increase/activation/configuration Indication message with the CI value explicitly that is distributed then for the CC that increases newly distributes the CI value before sending CC increase/activation/configuration Indication message.That is, in this CC increase/activation/configuration Indication message, need to comprise simultaneously following information:

1) frequency information of the CC that, increases newly/activate/dispose (perhaps C-CI value);

2), this that is distributed corresponding to above-mentioned each frequency information (or C-CI value) increases newly/activates/the CI value of the CC that disposes;

After terminal receives above-mentioned CC increase/activation/configuration Indication message, distribute CI value according to the CC of being designated as these and increasing newly/activate of base station/dispose, under this method, terminal does not then need own to increasing newly/activate/the CC generation CI value that disposes.

The assigning process of CI value was as follows when 202:CC replaced, referring to Fig. 5:

202a: the base station sends CC to terminal and replaces Indication message;

Wherein, the base station can send CC to terminal and replace Indication message, thereby satisfy terminal QoS needs according to factors such as terminal traffic needs or CC variations.

Wherein, it can be RRC message that CC replaces Indication message, MAC PDU or physical layer signaling.If RRC message, stride the carrier dispatching Indication message and can be carried at RRC and connect in the reconfiguration message and send.In addition, under the situation about between terminal is carried out the base station, switching, stride the carrier dispatching Indication message and can be carried in the switching command message and send.

Wherein, " replacement " here refers to specifically that the CC of increase/activation/configuration replaces and is removed/deexcitation/the separate CC of configuration.

202b: the base station will be removed/deexcitation/and the CI value of separating the CC of configuration distributes to the CC of increase/activation/configuration; Perhaps, discharge and to be removed/deexcitation/the separate CI value of the CC of configuration, according to the frequency of the CC of increases/activation/configuration or the size of C-CI value, the idle CI value from current minimum begins the value to the CC of increase/activation/configuration distribution CI successively;

Wherein, the base station will be removed/CC that the CI value of deexcitation/the separate CC of configuration is distributed to increase/activation/configuration specifically comprises: be removed/deexcitation/separate the frequency of the CC of configuration and the CC of increase/activation/configuration or C-CI value according to identical preset order (from small to large or from big to small), be removed/the CI value of deexcitation/separate the CC of configuration distributes to the CC of increase/activation/configuration.

Further, if the CC of increase/activation/configuration is more than being removed/deexcitation/the separate CC of configuration, according to the frequency of the CC of unnecessary increase/activation/configuration or the size of C-CI value, from the idle CI value of current minimum, distribute the CI value successively to the CC of unnecessary increase/activation/configuration;

If be removed/deexcitation/separate the CC of the CC of configuration, discharge (or take by weighing disappear) unnecessary being removed/deexcitation/separate CI value of the CC of configuration more than increase/activation/configuration.

202c: after terminal received CC replacement Indication message, terminal was distributed the CI value according to the method identical with the base station, sees step 202b for details, repeats no more here;

202d: optionally, after terminal is finished the work of CC replacement, send CC to the base station and replace acknowledge message.

Wherein, it can be RRC message that CC replaces acknowledge message, MAC PDU or physical layer signaling.If RRC message, stride the carrier dispatching Indication message and can be carried at RRC and connect in the reconfiguration message and send.In addition, under the situation about between terminal is carried out the base station, switching, stride the carrier dispatching Indication message and can be carried in the switching command message and send.

For example, receive before CC that the base station sends replaces message in terminal, the CC that terminal is being used is CC1, CC3, and the CC1 that CC5 is described here, CC3 and CC5, promptly the composition carrier wave that takies of the terminal C-CI value that is is 1,3 and 5.Simultaneously, from the specific CI value angle of terminal, we can suppose CC1, the current specific CI value of terminal of CC3 and CC5 is respectively 010,011 and 101, then replace message, when CC3 that uses new CC2 and CC4 to replace to use with indicating terminal and CC5, two kinds of implementations then can be arranged: promptly at first discharge CC3 and the shared CI value of CC5 that is replaced when the base station sends CC to terminal, then discharge after the CI value that CC3 and CC5 take, this moment, idle operable CI value had: 000,001,011,100,101,110,111.Then terminal and base station can be followed successively by CC2 and the CC4 distribution CI value that increases newly according to the size of C-CI value from the CI value beginning of the minimum of current free time.Be that current minimum idle CI value is 000, the CI value of then new composition carrier wave CC2 should be 000, and the CI value of new composition carrier wave CC4 is the next one CI value of free time, and promptly 001.Perhaps, more directly, terminal and base station also can be directly with the CC3 that is replaced and CC5 according to the ordering of C-CI value, with its CI value (promptly 011 and 101), pay initiate CC2 and CC4 according to the size of C-CI value successively.As long as it is base station and terminal as according to principle from small to large above-mentioned or from big to small, can guarantee then that base station and terminal are respectively the CCs that increases newly and give identical CI value according to same rule, consistent with the CI value that keeps base station and terminal.

By above-mentioned example as can be seen, carrying out CC between replacement period, realizing the reasonable distribution of the CI value of CC, it is chaotic to avoid the CI value to distribute, successfully to realize striding carrier dispatching.

In addition, also can replace message at CC the CI value explicitly that is distributed is sent to terminal then for the CC that increases newly distributes the CI value before sending CC to replace message the base station.That is, in this CC replacement Indication message, need to comprise simultaneously following information:

1) frequency information of the CC that, increases newly/activate/dispose (perhaps C-CI value)

After terminal receives above-mentioned CC replacement message, terminal discharges those and is removed/deexcitation/the separate CI value of the CC of configuration, simultaneously according to the CC distribution CI value of being designated as these and increasing newly/activates of base station/dispose, under this method, terminal then do not need own to increase newly/activate/CC that disposes generates the CI value automatically.

203:CC is removed/and deexcitation/assigning process of CI value is as follows when separating configuration, referring to Fig. 6:

203a: the base station sends CC to terminal and is removed/deexcitation/separate the configuration Indication message;

Wherein, the base station can send CC to terminal to be removed/deexcitation/separate the configuration Indication message, thereby satisfy terminal QoS needs according to factors such as terminal traffic needs or CC variations.

Wherein, CC is removed/deexcitation/and to separate the configuration Indication message can be RRC message, MAC PDU or physical layer signaling.If RRC message, stride the carrier dispatching Indication message and can be carried at RRC and connect in the reconfiguration message and send.In addition, under the situation about between terminal is carried out the base station, switching, stride the carrier dispatching Indication message and can be carried in the switching command message and send.

203b: the base station discharges the CI value that (or take by weighing disappear) was removed/deexcitation/separated the CC of configuration, and the CI value of other CC remains unchanged;

Wherein, " other CC " is meant except that being removed/CC of designated state the CC of deexcitation/separate configuration.

203c: terminal is distributed the CI value according to the method identical with the base station, sees step 203b for details, repeats no more here;

203d: optionally, terminal finishes CC and removes/deexcitation/separate the work of configuration after, send CC to the base station to be removed/deexcitation/separate configure-ack message.

Wherein, CC is removed/deexcitation/and to separate configure-ack message can be RRC message, MAC PDU or physical layer signaling.If RRC message, stride the carrier dispatching Indication message and can be carried at RRC and connect in the reconfiguration message and send.In addition, under the situation about between terminal is carried out the base station, switching, stride the carrier dispatching Indication message and can be carried in the switching command message and send.

In addition, some CC are removed/deexcitation/separate configuration after, after the CC of perhaps some being removed/deexcitation/separate configuration is replaced by the CC of some increase/activation/configuration,, then may bring certain negative effect to CI value multiplexing if the CI value of the CC of current designated state always remains unchanged." the CI value is multiplexing ", when being meant that the CI value used when terminal is only as the 1-2 bit, agreement regulation CI value takies 3 bits at present, then remaining 1 or 2 bits can be used to other indications, for example when the CI value only took 2 bits, it was 2 symbols or 3 symbols that then remaining 1 bit can be used for indicating the symbolic number of current PDCCH channel occupancy to terminal.Therefore, in order to guarantee the flexibility of physical layer multiplex CI value remaining bits, avoid reshuffling/resetting of unnecessary CI value simultaneously, present embodiment can be reshuffled the CI value/reset and be carried out following restriction:

The quantity of the CC of current designated state is smaller or equal to 2 N power, and the maximum CI value of current use is carried out reshuffling/resetting of CI value during greater than N power of 2; Wherein, N=1,2 ..., a-1, the bit number that a takies for default CI value, LTE (Long Term Evolution, Long Term Evolution) stipulates a=3 at present.

Wherein, the reshuffling/reset of CI value, being meant can be according to the frequency of the CC of designated state or the preset order of C-CI value institute foundation (from small to large or from big to small), and the CC that is followed successively by designated state begins to distribute the CI value from designated value, and designated state is state of activation or configuration status.Wherein, this designated value can be the value of zero or non-zero.In the CC of designated state, there are one or more CI values of not using, perhaps there is not the CI value, the CC that perhaps has the special designated state of static changeless CI value, then when the CC to designated state distributes the CI value not to the CC distribution CI value of these special designated states.If it is 0 that the CC of special designated state has changeless CI value, then designated value can be the value of a non-zero, is not 0 if the CC of this special designated state has changeless CI value, and then designated value can be zero.

Perhaps, when the base station sends CC renewal Indication message to terminal, according to the pre-conditioned Indication message of reshuffling/resetting of the CC of expection designated state being carried out the CI value that sends to terminal; Reshuffling/resetting of CI value carried out to the CC of expection designated state in the base station.Accordingly, terminal receives CC that the base station sends when upgrading Indication message, receives the Indication message of reshuffling/resetting that the CC to the expection designated state that the base station sends carries out CI value, reshuffling/resetting the CC execution CI value of described expection designated state.

Wherein, the CC of expection designated state be meant terminal or base station upgrade Indication message according to CC and carried out corresponding C C increases/activation/configuration, CC and be removed/deexcitation/separate dispose or the CC replacement operation after, the CC of the designated state that terminal or base station should be used.

Wherein, pre-conditioned at least one that comprises in pre-conditioned one and pre-conditioned two;

Pre-conditioned one is: the base station needs multiplexing CI value;

Pre-conditioned two are: the quantity of the CC of expection designated state is smaller or equal to 2 N power, and the maximum CI value of current use is greater than 2 N power; Wherein, N=1,2 ..., a-1, the bit number that a takies for default CI value, LTE stipulates a=3 at present.

In addition, consider that the scene of RRC connection re-establishment takes place terminal, so-called RRC connection re-establishment, be meant that terminal is under the situation that Radio Link Failure or handoff failure take place, terminal can be selected to rebulid RRC with original serving BS/Serving cell and be connected, therefore, terminal also can be carried out reshuffling/reset process of CI value in following situation, that is:

When receiving the RRC connection re-establishment message that the base station sends or when receiving article one RRC after the base station is sending RRC connection re-establishment message when connecting reconfiguration message, execution CI value is reshuffled/reset.
