The embodiment of the application provides a multi-connection management method and a multi-connection management product, wherein a network device indicates a terminal device to enter an SCG deactivation state by sending an SCG deactivation instruction to the terminal device, and at least one function of the terminal device in the SCG is suspended, so that the power consumption of the terminal device is reduced, and the service life of a battery of the terminal device is prolonged. In order to better understand the multi-connection method, the reference signal receiving method, and the communication apparatus disclosed in the embodiments of the present application, a network architecture to which the embodiments of the present application are applicable is described below. The method disclosed by the embodiment of the application can be applied to a 5G New radio access technology (New RAT), NR) system; but also to other communication systems where a presentity needs to transmit a reference signal (e.g., SRS) to another entity. A network architecture to which the method disclosed in the embodiments of the present application is applicable will be described first.

Referring to fig. 1-a, fig. 1-a is a schematic diagram of a network architecture according to an embodiment of the present application. As shown in fig. 1-a, the network architecture is applicable to a scenario in which reference signals are transmitted in multiple time units, i.e., a scenario in which reference signals are transmitted through multiple bundled and consecutive time units. A network device is an entity on the network side, such as a gNB, for transmitting or receiving signals. A terminal device is an entity, such as a mobile phone, on the user side for receiving or transmitting signals. Since the base station and the UE have many application scenarios, the base station is taken as an example of a network device, and a User Equipment (UE) is taken as an example of a terminal device. As shown in fig. 1, the network architecture includes a base station (base station), UE1, UE2, and UE3. In the communication system, a base station can send downlink reference signals to UE 1-UE 3; the UEs 1 to 3 may perform downlink channel estimation, downlink channel quality measurement, cell search, and the like according to the downlink reference signal. In this communication system, UE1 to UE3 may transmit an uplink reference signal (e.g., SRS) to a base station; the base station may perform uplink channel estimation, uplink channel quality measurement, and the like according to the uplink reference signal.

First, DC technology in NR, and MR-DC architecture will be described.

The DC technology is an important technology introduced by 3GPP Release-12 Release. By the dual connectivity technology, the LTE macro station and the LTE small station can utilize the existing non-ideal backhaul (non-ideal backhaul) X2 interface to implement carrier aggregation, thereby providing a higher rate for users, and improving spectral efficiency and load balancing by using macro/micro networking. The terminal supporting double connection can be connected with two LTE base stations simultaneously, and the throughput of a single user is increased. Based on the DC technology in LTE, the 5G/NR system newly introduces a multi-connection (MR-DC) architecture, so that the UE can simultaneously maintain two connections on LTE and/or NR, the advantages of multi-connection are fully utilized, the data throughput is improved, the data/signaling transmission delay is reduced, and the data/signaling transmission reliability is improved. This is important for the requirements of 5G low-latency, high-reliability services, and large capacity requirements. In addition, such a multi-connection architecture is also beneficial for reducing data interruption and delay of the UE at handover. Meanwhile, for scenes such as (ng) EN-DC (enhanced-direct current) and the like which simultaneously keep LTE (long term evolution) and 5G connection, the problem of insufficient coverage in the initial stage of 5G network construction can be effectively solved.

As shown in fig. 1-B, is a MR-DC control plane architecture diagram for connecting to a 5G core network. In the MR-DC control plane architecture of the connected 5G core network, the UE is connected to both RRC of a master base station (MN) and (SN) of a secondary base station. The main base station is connected with the 5G core network through an NG-C interface. And the initial RRC information of the auxiliary base station is forwarded to the main base station by the Xn-C interface and then is sent to the UE by the main base station. After the secondary base station establishes the RRC connection with the UE, the connection re-establishment and other processes may be completed between the secondary base station and the UE, without the participation of the primary base station. The auxiliary base station can independently perform configuration strategy report, initiate switching and the like, and has higher independence. But the secondary base station cannot change the RRC state of the UE. Fig. 1-C is a diagram of MR-DC data plane connections to a 5G core network. MN and SN are connected through Xn-U interface, MN and SN are connected with User Plane Function (UPF) through NG-U interface.

The multi-connection management method provided by the embodiment of the application is described in detail below.

Fig. 2 is a flowchart of a multi-connection management method according to an embodiment of the present disclosure. As shown in fig. 2, the method may include:

201. the network device sends an SCG deactivation instruction.

The SCG deactivation instruction is used to instruct the terminal device to enter an SCG deactivation state, where the SCG deactivation state refers to that the terminal device suspends at least one function in an SCG to which the terminal device belongs. In the MR-DC architecture, cells to which a terminal accesses include an SCG and a Master Cell Group (MCG). The MCG is a set of serving cells associated with a Master Node (MN). The SCG is a set of serving cells associated with a secondary base Station (SN). Under the condition that the terminal equipment does not carry out double connection, the cell group accessed by the terminal equipment is MCG.

It should be noted that at least one function of the terminal device in the SCG to which the terminal device belongs includes at least one of a data bearer function, an uplink and downlink transmission function of a signaling bearer, monitoring of a downlink control channel, receiving of a downlink data channel, measurement and transmission of an uplink reference signal or an uplink feedback signal, measurement of a downlink reference signal, or measurement report feedback of the terminal device in the SCG to which the terminal device belongs. For example, the monitoring of the downlink control channel may be monitoring a Physical Downlink Control Channel (PDCCH); the downlink data channel may be a Physical Downlink Shared Channel (PDSCH); the uplink feedback signal may be Channel Quality Information (CQI).

In an optional implementation manner, the network device sends an SCG deactivation instruction to the terminal device under the first condition. The first condition includes that the network device does not perform data transmission with the terminal device through the SCG within the first time length, the signal quality of the SCG is not greater than a quality threshold value, or the network device receives at least one of an SCG deactivation request of the terminal device. In some embodiments, the network device may further determine whether to send an SCG deactivation instruction to the terminal device according to the reported measurement report of the terminal device, in which in this embodiment, the first condition further includes that a parameter in the reported measurement report received by the network device from the terminal device does not reach a preset threshold value, for example, a signal quality measurement value of the SCG does not reach a preset quality value.

In some embodiments, the SCG deactivation command is sent by the network device to the terminal device via Radio Resource Control (RRC) signaling or Medium Access Control (MAC) Control Element (CE).

In an optional implementation manner, the SCG deactivation instruction includes at least one of a reason why the network device indicates that the terminal device enters the SCG deactivation state, a duration of the terminal device maintaining the SCG deactivation state, and an indication whether the terminal device stores SCG configuration information. The reason why the network device indicates that the terminal device enters the SCG deactivation state may be that there is no data transmission with the terminal device within the first duration, or may be that an SCG deactivation request of the terminal device is received, which is not limited herein. The duration of the terminal device maintaining the SCG deactivation state may also be adjusted according to actual situations, and is not limited herein.

Optionally, the SCG deactivation instruction further includes a time threshold T1, and the SCG deactivation instruction is further used to indicate that the terminal device releases the SCG when the terminal device does not activate the SCG within the time threshold T1. The terminal device releasing the SCG means that the terminal device does not use the resource indicated by the SCG configuration information and deletes the SCG configuration information.

The network device may be a Master Node (MN) in the MR-DC, or a Secondary Node (SN) in the MR-DC. Under the condition that the network device is an SN, after receiving the signaling instruction of the MN, the network device directly sends the SCG deactivation instruction to the terminal device, for example, the network device sends the SCG deactivation instruction to the terminal device through a signaling radio bearer message 3 (SRB 3).

The embodiment of the application provides a multi-connection management method and a product, wherein a network device sends an SCG deactivation instruction to indicate a terminal device to enter an SCG deactivation state, and at least one function of the terminal device in the SCG is suspended, so that the power consumption of the terminal device is reduced, and the battery service life of the terminal device is prolonged.

Fig. 3 is a flowchart of a multi-connection management method according to an embodiment of the present disclosure. As shown in fig. 3, the method is a multi-connection management method on a terminal device side, and the method may include:

301. and the terminal equipment receives the SCG deactivation instruction.

The SCG deactivation instruction is used to instruct the terminal device to enter an SCG deactivation state, where the SCG deactivation state refers to that the terminal device suspends at least one function in an SCG to which the terminal device belongs. After receiving the SCG deactivation instruction sent by the network device, the terminal device enters an SCG deactivation state to reduce the power consumption of the terminal device and increase the battery service life of the terminal device.

In an optional implementation manner, the SCG deactivation instruction further includes a time threshold T4, and the SCG deactivation instruction is further used for instructing the terminal device to execute an SCG release operation when the SCG activation is not performed within the time threshold T4. In some embodiments, time threshold T4 is a time threshold T1 sent by the network device.

Fig. 4 is a flowchart of a multi-connection management method according to an embodiment of the present disclosure. As shown in fig. 4, the method is a multiple connection management method on a network device side, and the method may include:

401. the network device transmits a time threshold T3.

The time threshold T3 is used for the network device to instruct the terminal device to enter an SCG deactivation state when the terminal device does not perform data transmission with the network device through the SCG within the time threshold T3. The SCG deactivated state refers to the terminal device suspending at least one function in the SCG to which the terminal device belongs.

In some embodiments, when the network device does not perform data transmission with the network device through the SCG within the time threshold T3, the network device determines that the terminal device enters the SCG deactivation state. Further, the network device sends an SCG activation instruction to the terminal device in the SCG deactivation state, and instructs the terminal device to switch from the SCG deactivation state to the SCG activation state.

Optionally, the time threshold T3 is carried by at least one of system broadcast information, RRC signaling, or MAC CE. In some embodiments, the time threshold T3 is carried by separate signaling. In other embodiments, the network device multiplexes existing signaling to send time threshold T3 to the terminal device, or entrains time threshold T3 with existing signaling, such as sending time threshold T3 via SCG configuration information.

501. the terminal device receives the time threshold T5.

The time threshold T5 is configured by the network device and is used to indicate that the terminal device enters an SCG deactivation state when the terminal device does not perform data transmission with the network device through the SCG within the time threshold T5. In some embodiments, the time threshold T5 received by the terminal device is the time threshold T3 sent by the network device.

In some embodiments, after receiving a time threshold T5 configured by the network device, the terminal device starts an SCG deactivation timer, and if a timing duration of the SCG deactivation timer exceeds the time threshold T5 and the terminal device does not perform data transmission with the network device through the SCG within the timing duration, the terminal device enters an SCG deactivation state. In the implementation manner, the terminal device enters the SCG deactivation state when not receiving the SCG deactivation instruction and the terminal device does not perform data transmission with the network device through the SCG within the time duration indicated by the time threshold T5, so that the transmission of the signaling and the time duration for activating the SCG are reduced, and the power consumption of the terminal device is further reduced.

Optionally, the time threshold T3 is carried by at least one of system broadcast information, RRC signaling, or MAC CE. In some embodiments, the time threshold T5 is carried by separate signaling. In other embodiments, the network device multiplexes the existing signaling to send the time threshold T5 to the terminal device, or entrains the time threshold T5 in the existing signaling, for example, sends the time threshold T5 through the SCG configuration information.

601. the terminal equipment sends an SCG deactivation request to the network equipment.

The SCG deactivation request is used to request the network device to indicate the terminal device to enter an SCG deactivation state.
