Background technology
Move the developing direction that becomes modern communication technology with the broadband, 3GPP (3rd Generation Partnership Project, third generation partner program) is devoted to LTE (Long Term Evolution, Long Term Evolution) system is as the evolution of 3G system, and target is that development 3GPP wireless access technology is towards high data rate, the low delay and the evolution of optimization packet data application direction.In the mobile communication system in future, for example among back three generations (B3G:Beyond three Generation) or the LTE-A, system will provide higher peak data rate and cell data throughput, so system also needs wideer transmission bandwidth.
The development of present mobile communication, also increasing for the demand of frequency spectrum resource.Because the rare and modern communication technology of frequency spectrum resource is to the pursuit of broadband high-speed rate communication, the two has formed a pair of contradiction.For example, for the LTE-A system of the above-mentioned frequency spectrum of mentioning that needs the 100M bandwidth, under the condition that has the idle frequency spectrum resource, can be the frequency spectrum that directly distributes the 100M bandwidth for this system.Yet,, be difficult to find wide so blank untapped frequency spectrum resource usually for the rare present mobile communication of frequency spectrum resource.
For the LTE-A system, for supporting the system bandwidth wideer,, need be called member carrier again by with a plurality of LTE carrier waves such as 100MHz than LTE system, couple together use, specific implementation has dual mode:
A plurality of continuous LTE carrier waves are carried out polymerization, for LTE-A provides bigger transmission bandwidth; A plurality of discontinuous LTE carrier waves are carried out polymerization, for LTE-A provides bigger transmission bandwidth.As shown in Figure 1, be the schematic diagram of discontinuous carrier aggregation.
The research of standardization body is at present tended to, be that the design on each carrier wave is kept being consistent with LTE Release 8 as far as possible for carrier aggregation system design, thus guarantee the terminal of LTE R8 can each member carrier in carrier aggregation system on operate as normal.
For the ease of member carrier is managed, member carrier can be divided into different carrier set.For example, as shown in Figure 2, be a kind of controlling schemes of the member carrier collection that detects based on PDCCH.In Fig. 2, be the set of two downlink member carriers of terminal configuration of being in the RRC connection status: the member carrier collection S of activation
ActiveMember carrier collection S with the PDCCH detection
PDCCH, set wherein meets following relation:
S wherein
AllExpression be the set of all downlink member carrier.
Yet, at present for the set of the member carrier of terminal monitoring, also there is not effective message informing scheme, allow the base station in time notify the set of its member carrier that need monitor of terminal, especially member carrier collection is after configuration or upgrading, therefore, be necessary to propose a kind of effective control signaling send mode, be used for the member carrier collection configuration and the renewal of indicating terminal.

Aspect that the present invention adds and advantage part in the following description provide, and part will become obviously from the following description, or recognize by practice of the present invention.
Embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Below by the embodiment that is described with reference to the drawings is exemplary, only is used to explain the present invention, and can not be interpreted as limitation of the present invention.
In order to realize the present invention's purpose, embodiments of the invention have proposed a kind of method of member carrier collection indication, may further comprise the steps: terminal receives the signaling information that the base station sends; Described terminal is obtained the aggregate information of corresponding member carrier according to described signaling information, monitors corresponding member carrier.
As shown in Figure 3, the method flow diagram for the member carrier collection of embodiment of the invention proposition is indicated may further comprise the steps:
Step S101: terminal receives the signaling information that the base station sends.
In order to realize the set of the member carrier that indicating terminal is monitored, the embodiment that the present invention proposes can control by the control signaling of high-level signaling or L1/L2 layer, the above-mentioned information of notice terminal, promptly above-mentioned signaling information comprises the control signaling of high-level signaling or L1/L2 layer.
More specifically, high-level signaling for example is the RRC signaling, and the RRC signaling that affirmation mechanism is arranged that terminal reception base station sends is indicated the aggregate information of described member carrier; Perhaps
The L1/L2 that terminal receives the employing ACK affirmation of base station transmission controls the aggregate information that signaling is indicated member carrier.As shown in Figure 4, control the schematic diagram of signaling for employing has the L1/L2 of ACK affirmation, terminal UE is confirmed the L1/L2 control signaling of receiving base station eNodeB by feeding back ACK.
Step S102: terminal is obtained the aggregate information of member carrier according to signaling information, monitors corresponding member carrier.
In step S102, the aggregate information of member carrier can embody by the multiple form of expression.
For example, the aggregate information of member carrier is indicated by the mode of bit mapping bitmap.
In conjunction with the accompanying drawings 2, be illustrated: the set of the form indication member carrier of the member carrier by physics, the indication of the set of different member carriers can be combined, and also can transmit separately.For example as shown in Figure 2,5 member carriers are arranged in the system, be used in reference to informational needs 5 bits of the person's of being shown as carrier set so, the member carrier collection S in describing with background
ActiveMember carrier collection S with the PDCCH detection
PDCCHFor example describes, the member carrier collection S of activation
ActiveMember carrier collection S with the PDCCH detection
PDCCHAdopt independently 5 bits indications, wherein the corresponding member carrier of 1 expression belongs to current set, for example: 11001 expressions be the member carrier collection S that activates

PDCCHInformation be 011, the implication of its expression is S
PDCCHSet in member carrier be member carrier 2 and 5.
In addition, the aggregate information of member carrier can also be by the ID indication of member carrier.For example,, a member carrier can only be arranged in certain member carrier collection if for each terminal, so can be by the current member carrier collection of member carrier ID indication of physics.For example: 5 member carriers are arranged, in the current carrier aggregation system if the S of terminal
PDCCHThe set of member carrier has only 1 member carrier, needs the information of one 3 bit to be used to indicate current S so
PDCCHThe set of member carrier.
In the concrete signaling message that terminal receives, for example, when the message signaling is L1/L2 control signaling, by L1/L2 control signaling configuration member carrier set, with member's carrier wave number is that 5 situation is an example, adopt the indicating means of bit mapping bitmap, in the information field of Downlink Control Information DCI, need to comprise the information field in the following form
Information field |
The mode of Bitmap |
Member carrier collection 1 |
5 bits |
Member carrier collection 2 |
5 bits |
Member carrier collection 3 |
5 bits |
...... |
...... |
For the indication of member carrier collection, can be by a member carrier collection that the DCI joint instructions are all, member carrier collection that also can an indicating section, for example indication of the set by keeping some member carrier of reserve, as adopt 0 to fill.
In addition, for the indication of member carrier collection, also can each member carrier collection indicate by a DCI separately.
Member carrier collection can be the member carrier collection S that activates
Active, the member carrier collection S that detects of PDCCH
PDCCH, and the member carrier collection that activates of PUSCH etc.
