Description
Technical field
The present invention relates to wireless communication technology fields, are more specifically to supporting across eNB carrier wave polymerization（Inter-
ENBCA, Inter-eNB Carrier Aggregation）In system, the configuration and activation of SCell (Secondary Cell)
Method and terminal.
Background technique
LTE at present（Long Term Evolution）In system, the maximum bandwidth that each cell is supported is 20MHz, in order to
The peak rate of UE is improved, LTE-Advanced system introduces carrier aggregation technology.By carrier aggregation technology, UE can be same
When and the work that is controlled by the same eNB communicated in the cell of different carrier frequencies, so that transmission bandwidth is up to 100MHz, from
And the uplink and downlink peak rate for the UE that can be multiplied.
For working in the UE under carrier wave polymerization, the small of polymerization divides into PCell（Primary Cell）And SCell
（Secondary Cell）.
PCell has been merely able to one, and is constantly in state of activation, and PCell can only be changed by handoff procedure,
And UE can only send and receive NAS information in PCell, and PUCCH can only also be sent in PCell.
According to the ability of UE, eNB can be reconfigured by RRC（RRC Reconfigurarion）Process to UE configure one or
Multiple SCell.The configuration process of SCell is as shown in Figure 1, the configuration information of each SCell is included in
In SCellToAddModList-r10 message in RRCConnectionReconfiguration message,
SCellToAddModList-r10 message includes the index of each SCell（SCelllIndex）, the physics ID of SCell, downlink
Carrier frequency, the specific radio resource configuration parameters of cell and the specific radio resource configuration parameters of UE etc..Wherein cell is specific
Radio resource configuration parameters include system broadcast message in SCell needed for all UE content, to ensure UE without passing through
Read the specific wireless resource configuration of SCell cell needed for the system broadcast message in SCell obtains.
In order to reduce the power consumption of UE, SCell after configuring, is in unactivated state（Deactivated）.ENB is logical
It crosses the MAC Control Element activation of MAC layer and deactivates a SCell, the MAC Control Element of activation/deactivation SCell occupies one
A byte, as shown in Fig. 2, the corresponding logic channel ID of the MAC Control Element is 11011.Wherein R is reservation bit, is set as 0；
CiThe state for the SCell that corresponding SCellIndex is i, i.e., if CiIt is 1, then the SCell of SCellIndex=i is state of activation；
If CiIt is 0, then the SCell of SCellIndex=i is unactivated state.
After each SCell activation, UE can start a corresponding packet data inactivity timer.If UE is on the SCell
It detects PDCCH or detects the PDCCH for the SCell on other serving cells, this will be restarted and deactivated
Active timer.If packet data inactivity timer is overtime, UE thinks that the SCell enters unactivated state.In addition, if UE receives band
The RRC reallocation message of switching command, then UE thinks that the SCell of all configurations enters unactivated state.SCell from state of activation into
Enter unactivated state, UE will empty the corresponding all HARQ cachings of the SCell.
If a SCell is in unactivated state, or enters unactivated state from state of activation, UE should：
PDCCH is not monitored on the SCell；
It is not listening to the PDCCH for the SCell；
SRS and UL-SCH is sent not on the SCell；
The CQI/PMI/RI of the SCell is not reported；
On the contrary, UE needs if a SCell is active：
PDCCH is monitored on the SCell（In self scheduling）；
Monitor the PDCCH for being directed to the SCell；
SRS is sent on the SCell according to the configuration of eNB
Report the CQI/PMI/RI etc. of the SCell.
In order to keep the behavior between eNB and UE consistent in time, if UE receives SCell activation life on subframe n
It enables, UE should be executed in the operation under SCell state of activation since subframe n+8；If UE receives SCell on subframe n and goes
Activation command, operation UE unrelated with CSI in the operation under SCell unactivated state should execute before subframe n+8, UE
Operation relevant to CSI should be executed in subframe n+8 in the operation under SCell unactivated state.
According to the regulation of current LTE-Advanced agreement, UE in SCell the Timing Advance of PUSCH and SRS and
It is identical in PCell.
In order to extend the application range of carrier aggregation technology, the peak rate of UE is further increased, the carrier wave polymerization across eNB
Technology is likely to become the developing direction of LTE-Advanced.So-called across eNB carrier aggregation technology refer to the same UE simultaneously into
The cell of row data transmission be not confined to the same eNB, i.e. these cells can be subordinated to different eNB, as shown in Figure 3.
In this way, can still increase the work belt of UE by carrier aggregation technology under the network environment by different eNB overlapping covering
It is wide.
But across eNB carrier aggregation technology is different from the characteristics of existing same eNB carrier aggregation technology, also gives carrier aggregation technology
Application bring new problem, such as in the configuration process of SCell, SCell needs to configure dedicated radio resource to UE
Parameter, and the specific radio resource configuration parameters of these parameters and cell are different, the former is dynamic, and the latter is semi-static
's.This requires the eNB of PCell subordinate to interact before configuring SCell to UE with the eNB of SCell subordinate, obtains
The eNB of SCell subordinate is the private radio configuration parameter of UE configuration.In addition, in the polymerization of across eNB carrier wave, the geographical location eNB
Difference will lead to the distance of UE and different eNB there are larger difference, therefore UE sends time of upstream data in SCell and mentions
Preceding amount cannot be equal to its Timing Advance that data are sent in PCell, this will have an impact the Activiation method of SCell.
As it can be seen that the configuration of SCell and activation will face many new problems in the carrier aggregation technology across eNB,
It cannot be simply multiplexed method described in existing LTE-Advanced agreement, and for current research achievement, not yet
For the solution of these problems.

It manages layer resource and SCell eNB scheduler is the foundation that UE selects uplink and downlink data and signalling mode.
Step 402：SCell eNB replys SCell configuring request feedback message, is UE distribution including SCell eNB
New C-RNTI, the dedicated physical layer configuration parameter of UE, etc..
SCell eNB is that UE distributes a new C-RNTI, is existed as physical label of the UE in SCell, and for UE
The scrambling of the decoding of down physical channel and uplink physical channel in SCell.The C-RNTI can be with C- of the UE in PCell
RNTI is identical, can also be different with C-RNTI of the UE in PCell.
The SCell configuring request feedback message that SCell eNB is replied includes the C-RNTI that above-mentioned SCell eNB is UE distribution
With dedicated physical layer configuration parameter of the UE in SCell, such as PDSCH configuration parameter, PUSCH configuration parameter of the UE in SCell
With uplink power control parameter etc..
Step 403：Information in SCell configuring request feedback is notified UE by RRC reconfiguration message by Pcell eNB.
The configuration of SCell is realized by RRC reconfiguration course, will be carried in RRC reconfiguration message and be believed needed for SCell configuration
Breath.It should include the index of the SCell, SCell cell needed for UE general physical layer configuration parameter and step in these information

Parameter and the specific physical layer configuration parameter of UE save C-RNTI of the UE in the SCell.
In addition, the application also proposed the Activiation method of SCell in across eNB carrier aggregation system a kind of, as shown in figure 5,
Specific step is as follows：
Step 501：PCell eNB sends SCell to SCell eNB and activates request message.
It should include UE ID that SCell, which activates request message, which can be UE in the S- of C-RNTI, UE of SCell
The C-RNTI and UE of TMSI, UE in PCell are used for one or more of the random value of contention resolved.
In addition, if the activation of SCell is since it is desired that SCell supports the new service request of UE, or SCell is needed to share
PCell partial service and the corresponding RB of this partial service（Radio Bearer）There is no establish in SCell, that is to say, that swashs
RB corresponding to the business demand of SCell living is not established in the SCell, then SCell is activated in request message and should be established comprising RB
Information.
Step 502：SCell eNB, which replys SCell activation, receives the response, and whether notice PCell eNB allows swashing for SCell
It is living, when permitted, step 503 is executed, it is no to then follow the steps 504.
SCell activates the content in receiveing the response to can be " SCell is allowed to activate " or " refusal SCell is activated ", if
" refusal SCell activation ", then SCell activation receive the response in can additionally include " Reason For Denial " and/or " retardation time ".
Step 503：If the content that the SCell activation request that PCell eNB is received is receiveed the response is " SCell to be allowed to swash
It is living ", then SCell activation instruction is sent to UE, and execute step 505.
If SCell activation request is receiveed the response, the content of middle message is to carry in " SCell is allowed to activate " and message
SCell eNB is the dedicated PRACH resource information of UE distribution, then PCell eNB notifies UE that activation should by PDCCH Order
SCell.Specifically, the dedicated PRACH resource information and SCell that SCell eNB is UE distribution are carried in PDCCH Order
Mark, such as the index of SCell.After UE receives the PDCCHOrder, i.e., carried out using the dedicated PRACH resource of carrying
Row synchronizes.
If SCell activation request is receiveed the response, the content of middle message is " SCell is allowed to activate ", but does not include in message
SCell eNB is the dedicated PRACH resource information of UE distribution, then SCell active mode and existing specification define identical, i.e., logical
It crosses MAC layer SCell activation/deactivation control unit and neutralizes the corresponding bit notification UE of the SCell index and activate the SCell.
In addition, after determining allows SCell to activate, needing to decide whether to distribute for UE dedicated for SCell eNB
PRACH resource, in general, can adjudicate UE and itself will uplink loss when, distribute dedicated PRACH resource for the UE,
And it is sent to PCell eNB, and when adjudicating UE and itself keeps uplink synchronous, no longer dedicated PRACH resource is distributed for UE.When
So, other feasible judgement modes can also be used, the application is not construed as limiting this.
Step 504：If the content that the SCell activation request that PCell eNB is received is receiveed the response is that " refusal SCell swashs
It is living ", then PCell eNB saves " Reason For Denial ".
Further, if in message including " retardation time ", PCell eNB should be at least somebody's turn to do in the backward of " retardation time "
SCell eNB sends the request of SCell activation next time.
Step 505：UE starts the communication between SCell eNB according to the SCell activation instruction received.
If SCell activation instruction is PDCCH Order, usual SCell eNB has discharged the dedicated uplink money of the UE
Source, such as PUCCH and SRS resource etc., therefore the dedicated PRACH resource initiation that UE needs to indicate by PDCCH Order is non-competing
The PRACH process and SCell eNB striven obtain uplink synchronous, and obtain PUCCH and SRS configuration, then execute it is subsequent handle into
Communication between capable and SCell eNB.
If SCell activation instruction is sent by the activation/deactivation control unit of MAC layer, need UE into one
Step judges itself and SCell eNB currently whether in uplink sync status, if it is not, then RACH of the UE according to the SCell
It is configured with PRACH, uplink synchronous is obtained by the PRACH process and SCell eNB of competitive mode, and obtain PUCCH and SRS matches
It sets, then executes following processing progress and the communication between SCell eNB；It is carried out if it is, UE directly executes following processing
With the communication between SCell eNB.
Specifically, after UE and SCell eNB obtains uplink synchronous and obtains UE specific PUCCH and SRS configuration, or
UE and certain SCell receives the activation sent by the activation/deactivation control unit of MAC layer in the case where being in uplink synchronous
Instruction, the behavior of UE are as follows：
PDCCH is monitored on the SCell（It is decoded by UE in the C-RNTI of SCell）；
SRS is sent on the SCell according to the configuration of SCell eNB；
Report the CQI/PMI/RI of the SCell（It is scrambled by UE in the C-RNTI of SCell）Deng.
Above-mentioned is the overall procedure of SCell configuration and Activiation method in the application.In addition, in above-mentioned treatment process, when
When PCell eNB notifies UE to carry out the activation of SCell by PDCCH Order mode, the processing of the side UE and existing processing mode
Also different.Based on this, a kind of method that the application gives UE activation SCell, as shown in fig. 6, this method process includes：
Step 601, the UE of across eNB carrier wave polymerization is supported to receive the activation that PCell eNB is sent by PDCCH Order
The notice of SCell.
Wherein, UE determines that received PDCCH Order is that the concrete mode of the notice of activation SCell can be：UE is received
The domain Carrier Indicator is checked after PDCCH Order, if the domain the CarrierIndicator value is the mark of SCell,
Then it is determined as activating the notice of SCell.
Step 602, UE initiates non-competing PRACH mistake by dedicated PRACH resource indicated by the PDCCH Order
Journey, with SCell eNB obtain uplink synchronous, obtain PUCCH and SRS configuration, and according to the PUCCH and SRS configuration carry out with
Communication between SCell eNB.
It correspondingly with above-mentioned process shown in fig. 6, can be with present invention also provides the terminal for supporting the polymerization of across eNB carrier wave
For implementing above-mentioned method shown in fig. 6.Fig. 7 is terminal structure schematic diagram provided by the present application.As shown in fig. 7, the terminal packet
It includes：Interface unit activates communication unit.
Wherein, interface unit, the notice for activating SCell sent for receiving PCell eNB by PDCCH Order,
And notifying activation communication unit, the dedicated PRACH resource that PDCCH Order is indicated is sent to the activation communication unit.Swash
