Problems solved by technology

However, in the prior art, after the network side configures the SCG for the UE, even if the data transmission on the SCG side has ended, the PSCell will always be in the active state, which will cause waste of power consumption when the interruption delay of the service type data transmission is relatively large; However, if the network side notifies the UE to release the SCG after the data transmission is interrupted, when the data transmission is initiated again, the network side needs to reconfigure the SCG for the UE, resulting in a large data transmission delay and increased signaling consumption. Fast recovery of data transfers has become an urgent problem to be solved

Embodiment 1

[0190] figure 1 A schematic diagram of UE access under DC provided by the embodiment of the present invention, as shown in figure 1 As mentioned above, under the DC, the UE accesses the MN, and the MN configures MCG configuration information for the UE. At the same time, the UE accesses the SN, and the MN or SN configures the SCG configuration information for the UE. In this embodiment, the MCG includes PCell, SCellA and SCellB; SCG includes PSCell, SCell1, SCell2 and SCell3, and the PSCell is the primary cell in the SCG. It should be understood that the embodiment of the present application can also be applied to not limited to figure 1 Shown is the UE access architecture.

[0191] figure 2 A schematic diagram of an SCG state control method provided by an embodiment of the present invention, the method includes:

[0192] S201: The UE determines whether there is data transmission in the SCG, if not, proceed to S202, and if yes, proceed to S203.

[0193] S202: Control the...

Embodiment 2

[0322] When the network-side device configures the SCG for the UE and the SCG is in an active state, the network-side device MN or SN may decide that the UE's SCG enters the sleep state, that is, sends an instruction to the UE that the UE's SCG enters the sleep state.

[0323] For the convenience of description, the three bearers that may be involved in the SCG are represented as DRB1, DRB2, and DRB3:

[0324] DRB1: PDCP in MN, RLC bearer in SN bearer (including split bearer and non-split bearer);

[0325] DRB2: PDCP bearer in SN and RLC bearer in SN (including split bearer and non-split bearer);

[0326] DRB3: The bearer of PDCP in SN and RLC bearer in MN (not including split bearer).

[0327] method one:

[0328] The MN determines that the SN enters the SCG sleep state.

[0329] Scenario 1: UE is only configured with DRB1.

[0330] Specifically, the MN determines that the DRB1 data transmission is over (there is no data transmission), the MN decides to put the SCG of the...

Embodiment 3

[0346] When the network-side device configures the SCG for the UE and the SCG is in the sleep state, the network-side device MN or SN may determine that the UE's SCG enters the active state, that is, send an instruction to the UE that the UE's SCG enter the active state.

[0347] For the convenience of description, the three bearers that may be involved in the SCG are represented as DRB1, DRB2, and DRB3:

[0348] DRB1: PDCP in MN, RLC bearer in SN bearer (including split bearer and non-split bearer);

[0349] DRB2: PDCP bearer in SN and RLC bearer in SN (including split bearer and non-split bearer);

[0350] DRB3: The bearer of PDCP in SN and RLC bearer in MN (not including split bearer).

[0351] method one:

[0352] The MN determines that the SN enters the SCG activation state.

[0353] Scenario 1: UE is only configured with DRB1.

[0354] Specifically, the MN determines that there is data transmission in DRB1, the MN decides to switch the SCG of the UE from the sleep st...

Abstract

The invention discloses an SCG state control method and device, UE, an MN, an SN and a medium. The method comprises the steps of: enabling the UE to determine whether data transmission exists in an SCG or not; when it is determined that data transmission does not exist in the SCG, controlling a PSCell in the SCG to enter a sleep state; and when it is determined that data transmission exists in theSCG, controlling a PSCell in the SCG to enter an activated state. According to the embodiment of the invention, when it is determined that data transmission does not exist in the SCG, the UE controlsa PSCell in the SCG to enter a sleep state so as to avoid waste of power consumption, and meanwhile, the SCG does not need to be released, so that the SCG does not need to be configured again when the data transmission is initiated on the SCG side again, and the data transmission is scheduled in time on the SCG according to the CSI measurement result reported in the sleep state, thereby reducingthe data transmission time delay and providing a scheme for quickly recovering the data transmission under the condition of saving energy.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an SCG state control method, device, UE, MN, SN and medium. Background technique [0002] With the continuous development of communication technology, people put forward higher requirements on the transmission rate. In order to increase the transmission rate, a network architecture that can realize cooperation / aggregation between multiple evolved NodeBs (eNBs) is proposed. Under this architecture, a part of radio bearers (RBs) of user equipment (User Equipment, UE) is on a master cell group (Master Cell Group, MCG) managed by a master base station (master node, MN), and this part of RBs includes Control plane bearer (Signaling Radio Bearer, SRB) and user plane bearer (Data Radio Bearer, DRB). Another part of the same UE is borne on a secondary cell group (Secondary Cell Group, SCG) managed by a secondary base station (secondary node, SN). Because the same UE is ...
