The network device sends an SCG deactivation instruction to the terminal device to instruct the terminal device to enter the SCG deactivation state, and suspend at least one function of the terminal device in the SCG to reduce The power consumption of the terminal equipment increases the battery life of the terminal equipment. In order to better understand the multi-connection method, the reference signal receiving method, and the communication device disclosed in the embodiments of the present application, the following describes the network architecture to which the embodiments of the present application are applicable. The method disclosed in the embodiments of this application can be applied to 5G new radio access technology (New RAT (radio access technology), NR) system; it can also be applied to other communication systems, as long as there is an entity in the communication system that needs to send to another entity Reference signal (e.g. SRS). The following first introduces a network architecture to which the method disclosed in the embodiment of the present application is applicable.

Please refer to FIG. 1-A. FIG. 1-A is a schematic diagram of a network architecture disclosed in an embodiment of the present application. As shown in Figure 1-A, this network architecture is suitable for scenarios where reference signals are transmitted in multiple time units, that is, a scenario where reference signals are transmitted through multiple bound and continuous time units. A network device is an entity on the network side that is used to transmit or receive signals, such as gNB. A terminal device is an entity on the user side that is used to receive or transmit signals, such as a mobile phone. Since there are many application scenarios for base stations and UEs, the base station is used as an example of network equipment in the following, and user equipment (UE) is used as an example of terminal equipment. As shown in Figure 1, the network architecture includes a base station, UE1, UE2, and UE3. In this communication system, the base station can send downlink reference signals to UE1 to UE3; UE1 to UE3 can perform downlink channel estimation, downlink channel quality measurement, cell search, etc. according to the downlink reference signal. In this communication system, UE1 to UE3 can send uplink reference signals (such as SRS) to the base station; the base station can perform uplink channel estimation, uplink channel quality measurement, etc. according to the uplink reference signal.

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

DC technology is an important technology introduced in 3GPP Release-12. Through dual connectivity technology, LTE macro stations and small stations can use the existing non-ideal backhaul X2 interface to achieve carrier aggregation, thereby providing users with higher speeds, and using macro/micro networking to improve Spectrum efficiency and load balance. A terminal that supports dual connectivity can connect to two LTE base stations at the same time, increasing the throughput of a single user. Based on the DC technology in LTE, the 5G/NR system newly introduces a multi-connection (MR-DC) architecture, which enables the UE to maintain two connections on LTE and/or NR at the same time, making full use of the advantages of multi-connection and increasing data throughput Reduce data/signaling transmission delay and improve the reliability of data/signaling transmission. This is important for 5G low-latency, high-reliability services, and large-capacity requirements. In addition, this multi-connection architecture is also beneficial for reducing the data interruption and delay of the UE during handover. At the same time, for scenarios such as (ng)EN-DC that maintain LTE and 5G connections at the same time, it can effectively compensate for insufficient coverage in the initial stage of 5G network construction.

As shown in Figure 1-B, it is the MR-DC control plane architecture diagram connected to the 5G core network. In the MR-DC control plane architecture connected to the 5G core network, the UE is connected to both the RRC (master node, MN) and the secondary node (SN) of the secondary base station. The main base station is connected to the 5G core network through the NG-C interface. The initial RRC information of the secondary base station is forwarded to the primary base station by the Xn-C interface, and then sent by the primary base station to the UE. After the secondary base station establishes an RRC connection with the UE, processes such as re-establishing the connection can be completed between the secondary base station and the UE, and the participation of the primary base station is no longer required. The secondary base station can independently perform configuration policy reports, initiate handovers, etc., with high independence. But the secondary base station cannot change the RRC state of the UE. Figure 1-C is a connection diagram of the MR-DC data plane connected to the 5G core network. MN and SN are connected through an Xn-U interface, and MN and SN are connected with a user plane function (User Plane Function, UPF) through an NG-U interface.

The following describes in detail the multi-connection management method provided by the embodiment of the present application.

Fig. 2 is a flowchart of a multi-connection management method provided by an embodiment of the application. As shown in Figure 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 the SCG deactivation state, and the SCG deactivation state means that the terminal device suspends at least one function in the SCG to which the terminal device belongs. In the MR-DC architecture, the cells accessed by the terminal include SCG and master cell group (MCG). The MCG is a group of serving cells associated with a master node (master node, MN). SCG is a group of serving cells associated with a secondary base station (secondary node, SN). In the case that the terminal device is not dual-connected, the cell group that the terminal device accesses is the MCG.

It should be noted that at least one function of the terminal equipment in the SCG to which the terminal equipment belongs includes the data bearing function of the terminal equipment in the SCG to which it belongs, the uplink and downlink transmission function of the signaling bearer, the monitoring of the downlink control channel, and the monitoring of the downlink data channel. At least one of receiving, measurement and transmission of uplink reference signals or uplink feedback signals, measurement of downlink reference signals, or measurement report feedback. For example, the monitoring of the downlink control channel can be the monitoring of the physical downlink control channel (PDCCH); the reception of the downlink data channel can be the reception of the physical downlink shared channel (PDSCH); the uplink feedback signal , Can be channel quality indicator (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 at least one of the network device not performing data transmission with the terminal device through the SCG within the first time period, the signal quality of the SCG is not greater than the quality threshold, or the network device receives the SCG deactivation request of the terminal device.

In this embodiment, the first condition further includes that the network device receives the measurement report reported by the terminal device. The parameter does not reach the preset threshold value, for example, the signal quality measurement value of the SCG does not reach the preset quality value.

In some embodiments, the SCG deactivation instruction is sent to the terminal by the network device through radio resource control (radio resources control, RRC) signaling or medium access control layer (medium access control, MAC) control element (CE) equipment.

In an optional implementation manner, the SCG deactivation instruction includes the SCG deactivation instruction and also includes the reason why the network device instructs the terminal device to enter the SCG deactivation state, the duration of the terminal device maintaining the SCG deactivation state, and whether the terminal device saves the SCG At least one of the indications of the configuration information. The reason why the network device instructs the terminal device to enter the SCG deactivation state may be that there is no data transmission with the terminal device within the first time period, or it may be that the SCG deactivation request of the terminal device is received, which is not limited here. The duration for the terminal device to maintain the SCG deactivated state can also be adjusted according to the actual situation, and there is no limitation here.

Optionally, the SCG deactivation instruction further includes a time threshold T1, and the SCG deactivation instruction is also used to instruct the terminal device to release the SCG when the terminal device does not activate the SCG within the time threshold T1. Wherein, 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 (master node, MN) in MR-DC, or a secondary base station (secondary node, SN) in MR-DC. In the case that the network device is an SN, after the network device receives the signaling instruction from the MN, it sends the SCG deactivation instruction directly to the terminal device. For example, the network device sends a signaling radio bearer (SRB3) message to the terminal device. The SCG deactivation command is sent to the terminal device.

The embodiment of the application provides a method and product for multi-connection management. The network device sends an SCG deactivation instruction to instruct the terminal device to enter the SCG deactivation state, and suspend at least one function of the terminal device in the SCG to reduce the function of the terminal device.

After receiving the SCG deactivation instruction sent by the network device, the terminal device enters the SCG deactivation state to reduce the power consumption of the terminal device and increase the battery 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 also used to instruct the terminal device to perform the SCG release operation without activating the SCG within the time threshold T4. In some embodiments, the time threshold T4 is the time threshold T1 sent by the network device.

401. The network device sending time threshold T3.

The time threshold T3 is used by the network device to instruct the terminal device to enter the SCG deactivation state when the terminal device does not transmit data with the network device through the SCG within the time threshold T3. The SCG deactivated state means that the terminal device suspends at least one function in the SCG to which the terminal device belongs.

In some embodiments, if 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 deactivated state. Further, the network device sends an SCG activation instruction to the terminal device in the SCG deactivated state, instructing the terminal device to switch from the SCG deactivated state to the SCG activated 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 reuses existing signaling to send the time threshold T3 to the terminal device, or entrains the time threshold T3 in the existing signaling, for example, sending the time threshold T3 through SCG configuration information.

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, the terminal device starts the SCG deactivation timer after receiving the time threshold T5 configured by the network device. If the time duration of the SCG deactivation timer exceeds the time threshold T5, and the terminal device has not When data is transmitted between the SCG and the network device, the terminal device enters the SCG deactivated state. In this implementation, the terminal device enters the SCG deactivation state when it does not receive the SCG deactivation instruction and the terminal device does not transmit data to the network device through the SCG within the time period indicated by the time threshold T5, thereby reducing signaling The duration of transmission and activation of SCG further reduces the power consumption of terminal equipment.

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 reuses existing signaling to send the time threshold T5 to the terminal device, or entrains the time threshold T5 in the existing signaling, for example, sending the time threshold T5 through SCG configuration information.

The temperature threshold can be determined according to specific conditions, and there is no limitation here.
