Embodiment

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

Embodiment 1

Referring to Fig. 1, the present embodiment provides a kind of method of upgrading component carrier, comprising:

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

Wherein, CC renewal Indication message can also be: CC is removed Indication message, CC deexcitation Indication message or CC and separates configuration Indication message;

102: in the time that CC renewal Indication message is increase/activation/configuration of CC Indication message, according to frequency or C-CI (the Cell Specific Component Carrier Indicator of the CC of increase/activation/configuration, the specific carrier identifiers in community) size of value, successively from the CC distribution CI value of start to increasing/activate/configuration of the idle carrier identifiers CI value of current minimum;

In the time that CC renewal Indication message is CC replacement Indication message, the CI value of the CC of be removed/deexcitation/solution configuration is distributed to the CC of increase/activation/configuration; Or the CI value of the CC of be removed/deexcitation of release/solution configuration, according to the frequency of CC or the size of C-CI value of increase/activate/configuration, distributes CI value from the idle CI value beginning of current minimum to the CC of increase/activation/configuration successively;

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

In the time that CC renewal Indication message is be removed/deexcitation of CC/solution configuration Indication message, discharge the CI value of the CC of be removed/deexcitation/solution configuration;

Wherein, the "/" in the present embodiment represents "or".

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

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

It will be appreciated by those skilled in the art that increase/activation/configuration CC process, replace the interprocedual that process and the be removed/deexcitation of CC/solutions configure CC and do not have positive connection, 3 processes are each forms an independent embodiment.For example, can there is an embodiment, only the CC that increases, activates or configure be adopted and the similar processing procedure of embodiment mono-in this embodiment, and can adopt method same as the prior art, the method that adopts CI value to reconfigure completely in the time replacing CC.Also can in the time replacing CC, adopt processing method similar to Example 1, and in the time increasing, activate or configure CC, adopt the method for prior art, the method that CI value reconfigures completely.The described method reconfiguring is completely no matter which kind of CC to occur upgrade, and all CC after upgrading are all redistributed to CI value, and the present embodiment does not limit.

Embodiment 2

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

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

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

200a: after terminal RRC initially connects and set up, if base station need to start across carrier dispatching, base station sends across carrier dispatching indication information to terminal, the CC that is used to indicate terminal and is designated state distributes CI value;

Wherein, can also carry PDCCH (Physical Downlink ControlChannel across carrier dispatching indication information, Physical Downlink Control Channel) monitor set, be used to indicate terminal and need to monitor the PDCCH channel of CC, to obtain the schedule information of current all designated state CC.

Wherein, can be RRC (Radio Resource Control across carrier dispatching Indication message, Radio Resource control) message, MAC (MediaAccess Control, media interviews control) PDU (Protocol DataUnit, protocol Data Unit) or physical layer signaling transmission.If RRC message can be carried in RRC connection reconfiguration message and send across carrier dispatching Indication message.In addition, in the situation that switching between terminal execution base station, can be carried in switching command message and send across carrier dispatching Indication message.

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

Wherein, this designated value can be zero or the value of non-zero.When there being one or more CI values that do not use in the CC of designated state, or there is no CI value, or have the CC of the special designated state of static changeless CI value, in the time that the CC to designated state distributes CI value, the CC of these special designated states is not distributed to CI value.If it is 0 that the CC of special designated state has changeless CI value, 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 designated value can be zero.

200c: terminal receive that base station sends across after carrier dispatching Indication message, terminal is distributed CI value according to the method identical with base station, refers to step 200b, repeats no more here;

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

200d: optional, terminal completes across after carrier dispatching preparation, sends across carrier dispatching acknowledge message to base station.

Wherein, can be RRC message equally across carrier dispatching acknowledge message, MAC PDU or physical layer signaling.If RRC message can be carried in RRC connection reconfiguration message and send across carrier dispatching Indication message.In addition, in the situation that switching between terminal execution base station, can be carried in switching command message and send across carrier dispatching Indication message.

201:CC increases/activates/when configuration CI value assigning process as follows, referring to Fig. 4:

201a: base station sends CC to terminal to be increased/activates/configuration Indication message;

Wherein, base station can need or the factor such as CC variations according to terminal traffic, and sending CC to terminal increases/activate/configuration Indication message, thereby increases new CC for terminal, need to meet terminal QoS (Qualityof Service, service quality).

Wherein, increase/activation/configuration of CC Indication message can be RRC message, MAC PDU or physical layer signaling.If RRC message can be carried in RRC connection reconfiguration message and send across carrier dispatching Indication message.In addition, in the situation that switching between terminal execution base station, can be carried in switching command message and send across carrier dispatching Indication message.

201b: base station according to increasing/activate/frequency of CC or the size of C-CI value of configuration, successively from the idle CI value of current minimum, for newly increasing/activate/the CC distribution CI value that configures;

201c: terminal receives CC to be increased/activates/configure after Indication message, terminal is distributed CI value according to the method identical with base station, refers to step 201b, repeats no more here;

201d: optional, terminal completes after the work of increase/activation/configuration, sends CC increase/activation/configure-ack message to base station.

Wherein, CC increase/activation/configure-ack message can be RRC message, MAC PDU or physical layer signaling.If RRC message can be carried in RRC connection reconfiguration message and send across carrier dispatching Indication message.In addition, in the situation that switching between terminal execution base station, can be carried in switching command message and send across carrier dispatching Indication message.

For example, before terminal receives increase/activation/configuration of CC Indication message of base station transmission, the CC that terminal is being used is CC1, CC3, and CC1 described here and CC3, the C-CI value of the component carrier that terminal takies is 1 and 3.Meanwhile, from the specific CI value of terminal angle, we can suppose that CC1 and the current specific CI value of terminal of CC3 are respectively 010 and 011, and so now the operable CI value of terminal free time has: 000,001,100,101,110,111.Then when base station increases/activates/configuration Indication message to terminal transmission CC, while using new CC2 and CC4 with indicating terminal, terminal should start to be followed successively by according to the size of C-CI value the CC distribution CI value newly increasing from the minimum CI value of current free time.Be that current minimum idle CI value is 000, the CI value of new component carrier CC2 should be composed with 000, and the CI value of new component carrier CC4 is the next one CI value of free time, and 001.

Can be found out by above-mentioned example, during carrying out CC increase/activation/configuration, realize the reasonable distribution of the CI value of CC, avoid CI value to distribute chaotic, successfully to realize across carrier dispatching.

In addition, base station can be also that the CC newly increasing distributes CI value sending before CC increase/activate/configuration Indication message, then at CC increase/activate/configuration Indication message, distributed CI value explicitly is sent to terminal.In, increase at this CC/activation/configuration Indication message, need to comprise following information simultaneously:

1), newly increase/activate/frequency information (or C-CI value) of the CC that configures;

2) this, distribution corresponding to above-mentioned each frequency information (or C-CI value) newly increase/activate/the CI value of the CC that configures;

Terminal receives above-mentioned CC to be increased/activates/configuration Indication message after, distribute CI value according to the CC of being designated as these and newly increasing/activates of base station/configure, under this method, terminal do not need oneself to newly increasing/activate/the CC generation CI value that configures.

When 202:CC replaces, the assigning process of CI value is as follows, referring to Fig. 5:

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

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

Wherein, it can be RRC message that CC replaces Indication message, MAC PDU or physical layer signaling.If RRC message can be carried in RRC connection reconfiguration message and send across carrier dispatching Indication message.In addition, in the situation that switching between terminal execution base station, can be carried in switching command message and send across carrier dispatching Indication message.

Wherein, " replacement " here specifically refer to increase/activate/CC of configuration replaces the CC that be removed/deexcitation/solutions configures.

202b: the CI value of the CC of be removed/deexcitation/solution configuration is distributed to the CC of increase/activation/configuration in base station; Or the CI value of the CC of be removed/deexcitation of release/solution configuration, according to the frequency of CC or the size of C-CI value of increase/activate/configuration, distributes CI value from the idle CI value beginning of current minimum to the CC of increase/activation/configuration successively;

Wherein, the CC that the CI value of the CC of be removed/deexcitation/solution configuration is distributed to increases/activations/configuration by base station specifically comprises: preset order that the CC that be removed/deexcitation/solution configures and the frequency of the CC of increase/activation/configuration or C-CI value foundation are identical (from small to large or from big to small), the CI value of the CC that be removed/deexcitation/solution is configured is distributed to the CC of increase/activation/configuration.

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

If the CC of be removed/deexcitation/solution configuration more than increasing/activate/CC of configuration, discharge the CI value of the CC that (or take disappear) unnecessary being removed/deexcitation/solutions configure.

202c: terminal receives CC and replaces after Indication message, and terminal is distributed CI value according to the method identical with base station, refers to step 202b, repeats no more here;

202d: optional, terminal completes after the work of CC replacement, sends CC replace acknowledge message to base station.

Wherein, it can be RRC message that CC replaces acknowledge message, MAC PDU or physical layer signaling.If RRC message can be carried in RRC connection reconfiguration message and send across carrier dispatching Indication message.In addition, in the situation that switching between terminal execution base station, can be carried in switching command message and send across carrier dispatching Indication message.

For example, the CC that receives base station transmission in terminal replaces before message, and the CC that terminal is being used is CC1, CC3, and the CC1 that CC5 is described here, CC3 and CC5, the C-CI value that the component carrier that terminal takies is is 1,3 and 5.Simultaneously, from the specific CI value of terminal angle, we can suppose CC1, the current specific CI value of terminal of CC3 and CC5 is respectively 010,011 and 101, replace message when base station sends CC to terminal, when the CC3 that uses new CC2 and CC4 to replace to use with indicating terminal and CC5, can have two kinds of implementations: CC3 and the shared CI value of CC5 that first release is replaced, after discharging the CI value that CC3 and CC5 take, now idle operable CI value has: 000,001,011,100,101,110,111.Terminal and base station can start to be followed successively by according to the size of C-CI value the CC2 and the CC4 distribution CI value that newly increase from the minimum CI value of current free time.Be that current minimum idle CI value is 000, the CI value of new component carrier CC2 should be 000, and the CI value of new component carrier CC4 is the next one CI value of free time, and 001.Or, more directly, terminal and base station also can be directly by the CC3 being replaced and CC5 according to the sequence of C-CI value, by its CI value (011 and 101), pay according to the size of C-CI value the CC2 and the CC4 that newly add successively.As long as base station and terminal, according to same rule, as according to principle from small to large above-mentioned or from big to small, can guarantee that base station and terminal are respectively the CCs newly increasing and give identical CI value, to keep the CI value of base station and terminal consistent.

Can be found out by above-mentioned example, carry out between CC replacement period, realize the reasonable distribution of the CI value of CC, avoid CI value to distribute chaotic, successfully to realize across carrier dispatching.

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

1), newly increase/activate/frequency information (or C-CI value) of the CC that configures

Terminal receives above-mentioned CC and replaces after message, terminal discharges those and is removed/the CI value of the CC of deexcitation/solution configuration, simultaneously according to the CC distribution CI value of being designated as these and newly increasing/activates of base station/configure, under this method, terminal do not need own to newly increasing/activate/CC that configures generates CI value automatically.

When be removed/deexcitation of 203:CC/solution configuration, the assigning process of CI value is as follows, referring to Fig. 6:

203a: base station sends be removed/deexcitation of CC/solution configuration Indication message to terminal;

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

Wherein, be removed/deexcitation of CC/solution configuration Indication message can be RRC message, MAC PDU or physical layer signaling.If RRC message can be carried in RRC connection reconfiguration message and send across carrier dispatching Indication message.In addition, in the situation that switching between terminal execution base station, can be carried in switching command message and send across carrier dispatching Indication message.

203b: base station discharges the CI value of the CC that (or take disappear) be removed/deexcitation/solutions configure, and the CI value of other CC remains unchanged;

Wherein, " other CC " refers to the CC of the designated state except the CC of be removed/deexcitation/solution configuration.

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

203d: optional, terminal completes CC and removes/work of deexcitation/solutions configuration after, to be removed/deexcitation/solution of base station transmission CC configure-ack message.

Wherein, be removed/deexcitation/solution of CC configure-ack message can be RRC message, MAC PDU or physical layer signaling.If RRC message can be carried in RRC connection reconfiguration message and send across carrier dispatching Indication message.In addition, in the situation that switching between terminal execution base station, can be carried in switching command message and send across carrier dispatching Indication message.

In addition, after the configuration of be removed/deexcitation of some CC/solution, or the CC of some being removed/deexcitation/solution configuration by the CC of some increase/activations/configurations replacement after, if the CI value of the CC of current designated state always remains unchanged, may bring certain negative effect to CI value multiplexing." CI value is multiplexing ", while referring to the CI value using when terminal only for 1-2 bit, agreement regulation CI value takies 3 bits at present, remaining 1 or 2 bits can be used to other indications, for example, in the time that CI value only takies 2 bits, remaining 1 bit can be 2 symbols or 3 symbols for indicate 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, the present embodiment can be reshuffled CI value/reset and be limited as follows simultaneously:

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

Wherein, the reshuffling/reset of CI value, referring to can be according to the preset order of the frequency of the CC of designated state or C-CI value institute foundation (from small to large or from big to small), and the CC that is followed successively by designated state starts to distribute CI value from designated value, and designated state is state of activation or configuration status.Wherein, this designated value can be zero or the value of non-zero.When there being one or more CI values that do not use in the CC of designated state, or there is no CI value, or have the CC of the special designated state of static changeless CI value, in the time that the CC to designated state distributes CI value, the CC of these special designated states is not distributed to CI value.If it is 0 that the CC of special designated state has changeless CI value, 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 designated value can be zero.

Or, when 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 to CI value that sends to terminal; Reshuffling/resetting of CI value carried out to the CC of expection designated state in base station.Accordingly, terminal receives the CC that base station sends and upgrades when Indication message, receives the CC to expection designated state that base station sends and carry out the Indication message of reshuffling/resetting of CI value, the reshuffling/reset of the CC execution CI value to described expection designated state.

Wherein, the CC of expection designated state refer to terminal or base station upgrade Indication message according to CC and carried out corresponding CC and increase/activate/configuration, be removed/deexcitation of CC/solutions configure or CC replacement operation after, the CC of the designated state that terminal or base station should be used.

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

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

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

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

In the time receiving the RRC connection re-establishment message that base station sends or in the time receiving base station and sending Article 1 RRC after RRC connection re-establishment message and connect reconfiguration message, execution CI value is reshuffled/reset.
