Fig. 3 a is a kind of simplification schematic flow sheet of forming the carrier management method that the embodiment of the invention provides, and said method comprises:

S31a: physical downlink control channel commands is sent to subscriber equipment in the base station, with activate one or more composition carrier waves, and indication need to add Physical Downlink Control Channel and monitor the one or more composition carrier waves that collect.

Alternatively; Base station (eNB; ENodeB) can send PDCCH order to UE, think that UE activates one or more composition carrier waves, and in this PDCCH order, indicate whether and should to form carrier wave when forming carrier wave to join the PDCCH monitoring concentrated activating one with one or more bits (Bit).ENB can activate said CC through said one or more CC are added the PDSCH collection, and the CC that is activated can be used in data and transmits.Alternatively, eNB also can indicate in the composition carrier wave of a plurality of new activation each to form carrier wave respectively whether need to add PDCCH and monitor collection, and for example, eNB can use a bit indication respectively, and each is formed carrier wave and whether need add PDCCH and monitor collection; In addition, eNB also can concentrate the composition carrier wave of these new activation of indication whether need join PDCCH and monitor concentrate, and promptly eNB can only use these composition carrier waves that are activated of bit indication whether to be added into PDCCH to monitor and concentrate.If a new composition carrier wave that activates is added into PDCCH and monitors concentrated; Then eNB can further indicate the information of other composition carrier waves that can dispatch at the composition carrier wave of this new adding PDCCH monitoring collection; The said information that other form carrier wave comprises identifier, frequency information or PCI (the Physical Cell Identity that these form carrier wave; Physical Cell Identifier) one or more in the information such as promptly represent composition carrier wave that this new adding PDCCH monitors collection other the composition carrier wave of can which being dispatched.Other of said scheduling are formed carrier wave can comprise other composition carrier wave of new activation or other composition carrier waves that former PDSCH concentrates.If the new composition carrier wave that activates is added into PDCCH and monitors and concentrate, then eNB can further indicate these do not add PDCCH monitor collection new activation the composition carrier wave specifically by PDCCH monitor concentrate which or which form carrier wave and dispatch.In a word; ENB can concern to related (linkage) that UE indicates PDCCH to monitor the CC in CC and the PDSCH collection in the collection; If promptly PDCCH monitors in the collection one and forms carrier wave and have the linkage relation with a carrier wave in the PDSCH collection, show that promptly PDCCH monitors in the collection this and forms carrier wave and can dispatch the interior composition carrier wave of PDSCH collection that has the linkage relation.

In addition; If the new composition carrier wave that activates is an expansion CC (Extension CC) or CC segmentation (CC segment); Said expansion CC or CC segmentation are meant the CC that self can not work alone; Be self not have the PDCCH channel, can not dispatch voluntarily, control and dispatch the CC of use and can only depend on other CC with PDCCH channel.Promptly need have the schedule information of obtaining said expansion CC or CC segmentation on the CC of PDCCH channel at said other, then eNB can be in activating the PDCCH order of forming carrier wave the further composition carrier wave of this expansion CC of indication scheduling or CC segmentation.The composition carrier wave of this expansion CC of said scheduling or CC segmentation can be the interior composition carrier wave of current PDCCH monitoring collection, also can be that the needs of indicating in the PDCCH order of this activation composition carrier wave add the concentrated composition carrier wave of PDCCH monitoring.

Alternatively; The eNB reusable is used for the PDCCH order and the PDCCH order that is used for the renewal of PDCCH monitoring collection of carrier wave activation or deexcitation CC; Promptly in the PDCCH order, can use an indication information, for example a bit; Indicating current PDCCH order is the activation that is used to form carrier wave, still is used for the renewal that PDCCH monitors collection.For example, when said indication bit is 1, can represent that this PDCCH order is used for the activation of CC, indication UE need upgrade PDCCH monitoring collection in the PDCCH order simultaneously; And when said indication bit was 0, then this PDCCH order can be used for the renewal that PDCCH monitors collection.

Alternatively; ENB also can be when activating one or more composition carrier waves for UE; The current PDCCH of UE is monitored the part or all of CC that concentrates to be replaced or removes; Be that eNB uses PDCCH to order when activating new composition carrier wave as UE, need send to UE from the indications of concentrated replacement of PDCCH monitoring or the one or more CC that remove and the indication information of replacing or removing.

Selectively; ENB can be when concentrating current PDCCH monitoring one or more CC to remove from the PDCCH monitoring is concentrated; In this PDCCH order, indicate whether need said CC monitored to concentrate from PDSCH remove, promptly eNB can indicate whether deexcitation these are monitored from PDCCH and concentrate the CC that removes.If a CC is monitored to concentrate from PDSCH and removes, it will promptly no longer be used to transmit data by deexcitation.

S32a: subscriber equipment adds one or more composition carrier waves adding Physical Downlink Control Channel monitoring collection that Physical Downlink Control Channel is monitored collection according to the said indication of base station with needs.

UE is after the PDCCH order that receives the eNB transmission; Can confirm the new CC that activates according to the indication of PDCCH order; And whether need the one or more composition carrier waves that newly activate be added PDCCH monitoring collection; Be that UE determines whether current PDCCH monitoring collection is upgraded, and will add the CC adding PDCCH monitoring collection that PDCCH monitors collection.

S33a: subscriber equipment sends Physical Downlink Control Channel and monitors collection renewal acknowledge message to said base station.Alternatively, UE can send PDCCH monitoring collection renewal affirmation Indication message and give eNB behind renewal PDCCH monitoring collection, and this Indication message can be one or more bits.S33 is optional process in the present embodiment.

The base station needs the adding Physical Downlink Control Channel to monitor one or more composition carrier waves of collection through forming carrier wave activation or configuration messages indication when activating the composition carrier wave in the present embodiment; Make subscriber equipment can upgrade Physical Downlink Control Channel and monitor collection; Realization has reduced the activation time delay of forming carrier wave to the monitoring of PDCCH.

In the present embodiment; In order to reduce the number of times of UE blind Detecting PDCCH; Can come to design again PDCCH DCI form based on PDCCH DCI (Downlink Control Information, the Downlink Control Information) form of existing LTE (Long Term Evolution, Long Term Evolution).In LTE, UE is when detecting PDCCH, and whether the information among the PDCCH that needs to consider to be detected is legal data; For example, indicate PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) RB (Resource Block in the PDCCH information; Resource Block) number can be made as 2,3 or 5 multiple; Be called PUSCH RB allotment,, think that then this PDCCH is invalid PDCCH if UE detects PUSCH RB number when being different from PUSCH RB allotment.For LTE-AUE; Then can in the PDCCH DCI form of design again, use non-PUSCH RB allotment (like the PUSCH RB number of non-2,3 or 5 multiples); Be used for activation or the deexcitation of CC with indication LTE-AUE this PDCCH, perhaps indicate PDCCH monitor the interior CC of collection increase, delete or reshuffle etc.Particularly; Whether the CC of identifier and these new activation that can in the residue bits among the DCI of design again, comprise the CC of the activation of mentioning in the foregoing description is added into PDCCH is monitored the indication information of concentrating; Perhaps, can comprise PDCCH monitors needs to increase, delete the CC that perhaps reshuffles in the collection identifier among the said residue bits.

In addition; Also can in the Physical Downlink Control Channel of inheritance system, increasing new bit indication information, to indicate said physical downlink control channel commands be to be used for activating one or more composition carrier waves and being used for Physical Downlink Control Channel and monitoring collection and upgrade in new system; Whether the CC of identifier and these new activation that comprises the CC of the activation of mentioning in the foregoing description then among the residue bits in DCI is added into PDCCH is monitored the indication information of concentrating; Perhaps, can comprise PDCCH monitors needs to increase, delete the CC that perhaps reshuffles in the collection identifier among the said residue bits.Said new system can be further developing said inheritance system.

Alternatively; It is to be used for activating one or more composition carrier waves and being used for the renewal of Physical Downlink Control Channel monitoring collection in new system that reserved bit indication information in the Physical Downlink Control Channel of inheritance system capable of using is indicated said physical downlink control channel commands; Whether the CC of identifier and these new activation that comprises the CC of the activation of mentioning in the foregoing description then among other in the DCI residues bits is added into PDCCH is monitored the indication information of concentrating; Perhaps, can comprise PDCCH monitors needs to increase, delete the CC that perhaps reshuffles in the collection identifier among the said residue bits.

In addition; In connection procedure; When eNB uses one or more CC of PDCCH order deexcitation; Can monitor collection to PDCCH equally safeguard: promptly when using the PDCCH order with one or more CC deexcitation, the PDCCH of UE is monitored collection and upgrade again, eNB indication UE increases, deletes or replace the CC that PDCCH monitors in the collection.Alternatively; When deexcitation CC; Monitor collection if said CC by deexcitation belongs to PDCCH, eNB can indicate UE that this CC is monitored to concentrate from PDCCH and remove, and according to current CC configuring condition; The CC that PDCCH is monitored in the collection redistributes; The CC that promptly PDCCH is monitored in the collection increases, deletes or replaces, and in the PDCCH of this deexcitation CC order, notifies UE with lastest imformation, and UE increases, deletes or replace the CC that PDCCH monitors in the collection based on the lastest imformation of eNB indication then.
