The activation of supplementary cell (SCell)/deactivate

If MAC entity is configured with one or more SCell, network can activate and deactivate configured SCell. SpCell is active always.Network activates and deactivates SCell by sending activation/deactivated MAC control element.This Outside, MAC entity is that each configured SCell (SCell in addition to being configured with PUCCH, if any) is maintained SCellDeactivationTimer timer, and associated SCell is deactivated when it expires.Identical initial timer value is suitable For each example of sCellDeactivationTimer, and configured by RRC.It is first in addition and after the handover First deactivate configured SCell.After SCG change, configured SCG SCell is initially deactivated.

For the SCell of each TTI and each configuration, MAC entity is answered:

For being grouped the agreement of duplication

Whether first problem is that grouping should be supported to replicate in the new radio-dual link (EN-DC) of E-UTRAN.For band Having the EN-DC of NR main website, PDCP is NR PDCP, and agrees to support grouping duplication.But for the EN- with LTE main website DC, PDCP are LTE PDCP, and we must discuss whether this can be supported.

For downlink, there is no this feature is supported, because LTE PDCP has been carried out duplication and eliminates function. As long as PDCP PDU is copied to LTE RLC and NR RLC by the LTE PDCP in main eNB, there is no hold this feature UE is collateral The problem of.This depends entirely on the implementation of eNB.

However, for uplink, in order to support grouping to replicate, it is necessary to upgrade LTE PDCP in UE.This is possible to , but it is considered that this range beyond NR WI.This problem can be discussed in other WI of such as URLLC.

Propose 1: the application proposes that the grouping duplication in LTE PDCP should discuss in LTE version -15URLLC WI.

It is compulsory that Second Problem, which is for NR PDCP grouping copy function,.

Only just need to be grouped duplication in special circumstances during such as URLLC is transmitted or is switched.Because simultaneously not always needing It wants, so need not forcibly support.Grouping copy function whether should be supported according to each PDCP configuration of radio bearer characteristic.

Propose 2: the application proposes that the support to grouping copy function should be configured by each radio bearer.

Even if radio bearer is configured as supporting grouping duplication, PDCP transmitter is also not necessarily all PDCP PDU and executes Grouping duplication.Because only the useful such as severe radio condition of, important grouping are transmitted under specific condition for grouping duplication Deng the expectation only just execution grouping duplication when needing really.UE, which can be decided in its sole discretion, is switched on/off grouping copy function, or GNB can order UE with open/close copy function.

Propose 3: the radio bearer for supporting grouping copy function, the application propose, it should which dynamically control enables/stops With grouping copy function.

MAC CE is for being grouped the dynamic ON/OFF of duplication in PDCP.If PDCP duplication has been turned on, PDCP is sent Entity will replicate PDCP PDU, and be submitted to two different RLC entities.Two RLC entities are mapped to two differences Cell, in order to avoid sending the grouping of duplication on single subdistrict.In carrier wave polymerization (CA), it is possible to, when for example Corresponding Ci by being arranged to 0 receives activation/deactivated MAC CE or associated When sCellDeactivationTimer expires, SCell can be deactivated.Then, when the grouping that will send duplication on it When cell is deactivated, how UE goes if UE is received and had duplication=ON duplication activation command (for example, duplication MAC CE) It is to have a question.

When eNB not can know that the dead status of UE, suggestion according to the present invention can be applied.

The present invention proposes, when UE is received with duplication=ON duplication activation command (for example, duplication MAC CE (Dup MAC CE)) when, the deactivated SCell of the one or more of the UE activation grouping that UE will send duplication on it.

UE can receive information related with the duplication configuration of RB from eNB (or gNB).Replicate RB by a PDCP entity and Two RLC entity compositions.Replicating RB can be associated with two RLC entities.The configuration for replicating RB includes that RB is able to carry out grouping The instruction of duplication.Each RLC entity of duplication RB is mapped to different cells, that is, the data of two RLC entities are different It is sent in cell.

When UE receives duplication activation command (for example, having duplication=ON duplication from eNB via cell (serving cell) MAC CE) when, duplication of the UE based on duplication MAC CE activation duplication RB.UE starts to replicate RB, that is, is configured to execute Grouping duplication RB, executes grouping duplication.For example, duplication MAC CE can be with via LCID the or RB ID for including in duplication MAC CE The specific duplication RB of instruction.In this case, UE starts to execute grouping duplication for indicated particular copy RB.

When receiving with duplication=ON duplication MAC CE, UE checks the small of the RLC entity for being mapped to duplication RB Area is activated or is deactivated.If the cell for being mapped to the RLC entity of duplication RB is deactivated, UE automatically activates this small Area, that is, activate the cell in the case where not receiving activation/deactivated MAC CE.If cell has been activated, UE can be weighed Newly activate the cell.

If there is multiple duplication RB and multiple duplication RB are mapped to different cells, then UE can activate one simultaneously A or multiple cells.

When PCell or PSCell are always activated, the present invention can be only applied to SCell.

The activation of cell means using normal cell operation, it may be assumed that

SRS transmission in cell；

CQI/PMI/RI/PTI/CRI for cell is reported；

PDCCH monitoring in cell；

PDCCH monitoring to cell；

PUCCH transmission in cell, if be configured.

Start or restart cellDeactivationTimer associated with the cell；

Trigger PHR.

After activating one or more cells associated with one or more duplication RB, (transmission) of each duplication RB PDCP physical replication PDCP PDU, and the PDCP PDU of each duplication is submitted into each RLC reality relevant to PDCP entity Body.

Fig. 6 is the exemplary figure for being shown in cell activation when receiving duplication MAC CE.

1.UE can be configured there are four cell as example.In other words, as an example, can be configured for UE four small Area.As shown in Figure 6, cell 2 is activated, and other cells, that is, cell 1, cell 3 and cell 4 are deactivated.

2. as an example, UE can be configured, there are three RB.RB1 and RB2 is duplication RB, and RB3 is not replicated RB.Duplication RB1 is made of PDCP1 entity, RLC11 entity and RLC12 entity, replicates RB 2 by PDCP2 entity, RLC21 entity and RLC22 Entity composition, and RB3 is made of PDCP3 entity and RLC3 entity.MAC entity is independently of RB, that is, identical or different MAC Entity can be used for different RB.

3. RLC entity is mapped to cell using following relationship.RLC11 entity is mapped to cell 1 and cell 3, and RLC12 is real Body is mapped to cell 2, and RLC21 entity is mapped to cell 1 and cell 2, and RLC22 entity is mapped to cell 3, and RLC3 entity reflects It is mapped to cell 3 and cell 4.

4. duplication RB1 only sends PDCP PDU in cell 2, and replicates RB2 because deactivating cell 1 and cell 3 Also PDCP PDU is only sent in cell 2.Because cell 3 and cell 4 are deactivated, not replicated RB3 does not send any PDCP PDU。

5.MAC1 via activation cell, that is, cell 2, receive duplication activation command (for example, have duplication=ON answer MAC CE processed).UE can activate the duplication for replicating RB based on duplication MAC CE.

6.UE checks the state of activation for being mapped to the cell of duplication RB.UE discovery is mapped to the cell 1 and cell 3 of duplication RB It is deactivated.

7.UE activation is mapped to the cell 1 and cell 3 of duplication RB.However, UE, which is not activated, is mapped to the small of not replicated RB Area 4.In this case, UE can automatic activation cell 1 and cell 3, that is, in no feelings for receiving activation/deactivate MAC CE Activation cell 1 and cell 3 under condition.If cell 1 and cell 3 have been activated, UE can reactivate cell 1 and cell 3.

8. PDCP1 entity starts to execute grouping duplication after activation cell 1.And after having activated cell 3, PDCP2 entity starts to execute grouping duplication.Then, the PDCP PDU for replicating the duplication of RB1 is sent in cell 1 and cell 2, And the PDCP PDU for replicating the duplication of RB2 is sent in cell 3 and cell 2.Before activation cell 1, PDCP1 entity can The PDCP PDU of duplication can will not be submitted to RLC11 entity, and PDCP2 entity may not be submitted to RLC22 entity and be replicated PDCP PDU, until cell 3 is activated.

9. not replicated RB3 can send PDCP PDU in cell 3 after activation cell 3.PDCP3 entity can not PDCP PDU is submitted to RLC3 entity until activation cell 3.

10. UE stops then, when receiving duplication deactivation command (for example, having duplication=OFF duplication MAC CE) Execute the grouping duplication of duplication RB.However, UE does not change the state of activation of cell.In other words, UE maintenance is mapped to duplication RB Cell state of activation cell.Therefore, cell 1, cell 2 and cell 3 keep state of activation, and cell 4 keeps deactivating.
