Detailed ways

In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

Before describing the embodiments of the present invention in detail, a dual connectivity (Dual Connectivity, DC) technology is briefly described first.

At present, with people's pursuit of speed, delay, high-speed mobility, and energy efficiency, as well as the diversity and complexity of services in future life, the 3GPP international standards organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile ultra-broadband (eMBB), low-latency highly reliable communication (URLLC), and massive machine-type communication (mMTC).

eMBB still aims at users' access to multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, the capabilities and requirements vary greatly, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, electric power automation, telemedicine operations (surgery), traffic safety guarantee, etc. The typical characteristics of mMTC include: high connection density, small data volume, delay-insensitive services, low cost and long service life of modules, etc.

In the early deployment of NR, it is difficult to obtain complete NR coverage, so typical network coverage is wide-area Long Term Evolution (LTE) coverage and New Radio (New Ration, NR) island coverage mode. Moreover, a large number of LTE deployments are below 6GHz, and there is very little spectrum below 6GHz that can be used for 5G. Therefore, NR must study the spectrum application above 6GHz, while the coverage of high frequency bands is limited and the signal fades quickly. At the same time, in order to protect the mobile operators' investment in LTE in the early stage, the working mode of tight interworking between LTE and NR is proposed.

In order to realize 5G network deployment and commercial application as soon as possible, 3GPP completed the first 5G version, LTE-NR Dual Connectivity, or EN-DC for short, before the end of December 2017. The network deployment and networking architecture of the EN-DC is shown in Figure 1: Here, LTE serves as the master node (Master Node, MN), and NR serves as the secondary node (Secondary Node, SN). Wherein, the communication scenarios of the EN-DC include scenario 3A as shown in FIG. 2a and scenario 3 as shown in FIG. 2b.

Step S201, the terminal device receives first configuration information, where the first configuration information is used to indicate that the terminal device is configured with one first access network node and at least two second access network nodes.

In some embodiments, the terminal device receives radio resource control (Radio Resource Control, RRC) signaling sent by the network device, where the RRC signaling carries first configuration information, and the first configuration information is used to indicate that the terminal device is in Multi-connection mode, that is, the terminal device is configured with one first access network node and at least two second access network nodes.

In the embodiment of the present invention, the scenario in which the terminal device is configured with one first access network node and at least two second access network nodes includes at least the following two. The network architecture of the first scenario, as shown in Figure 5, the first access network node and at least two second access network nodes are connected to the first core network; in this scenario, the first access network node and the first There is a control plane connection between the core networks; the first access network node is an eLTE eNB, and the second access network node is a gNB; or the first access network node is a gNB, and the second access network node is an eLTE eNB; at least two The coverage of the second access network node may or may not overlap; the coverage of the first access network node and the second access network node overlap; in the first scenario, the first core network is 5G core network.

In some embodiments, the first configuration information is also used to indicate the unique identification (identity, ID) of the second access network node for the terminal device; that is, each second access network node is assigned a The unique identifier in the terminal device is the SN ID. The value of the SN ID can be allocated from 0 or 1; when the value of the SN ID is allocated from 1, the ID of the first access network node can be 0 by default.

In some embodiments, the state of the second access network node includes: a first state, a second state and a third state. When the second access network node is in the first state, the state of the cell served by the second access network node includes: a first state, a second state, and a third state. When the second access network node is in the second state, the state of the cell served by the second access network node includes: the second state. When the second access network node is in the third state, the state of the cell served by the second access network node includes: a second state and a third state. Optionally, when the cell served by the second access network node is in the third state, the terminal device performs RRM measurement and CQI measurement in the cell, but does not perform data transmission and data reception. In the embodiment of the present invention, the data transmission refers to sending data.

When the second access network node is in the first state, the terminal device is capable of performing at least one of the following: receiving and/or transmitting data of a cell in the first state, measuring a cell in the first state Radio resource management (Radio Resource Management, RRM), measure the RRM of the cell in the second state, measure the RRM of the cell in the third state, measure the channel quality indication of the cell in the first state and the cell in the third state (Channel Quality Indication, CQI), monitor and/or receive the physical downlink control channel (Physical Downlink Control Channel, PDCCH) of the cell in the first state, send the PDCCH of the cell in the first state, send the cell in the first state A channel sounding reference signal (Sounding Reference Signal, SRS), and a scheduling request (Scheduling Request, SR) of the cell in the first state is sent.

When the second access network node is in the second state, the terminal device can perform at least one of the following: stop receiving and/or transmitting data of the cell in the second state, measure the cell in the second state The RRM of the cell, stop measuring the CQI of the cell in the second state, stop monitoring and/or receiving the PDCCH of the cell in the second state, stop sending the PDCCH of the cell in the second state, and stop sending the PDCCH of the cell in the second state SRS, stop sending the SR of the cell in the second state.

When the second access network node is in the third state, the terminal device can perform at least one of the following: stop receiving and/or sending data of cells in the second state and in the third state, measure RRM of the cell in the second state, measure the CQI of the cell in the second state, measure the RRM of the cell in the third state, measure the CQI of the cell in the third state, stop listening and/or receive the cell in the second state and Stop sending the PDCCH of the cell in the third state, stop sending the PDCCH of the cell in the second state, stop sending the SRS of the cell in the second state, stop sending the SR of the cell in the second state, stop sending the cell in the third state stop sending the SRS of the cell in the third state, and stop sending the SR of the cell in the third state.

In some embodiments, the terminal device determines the first state or the second state of the second access network node according to the first signaling; optionally, the first signaling is PDCCH and/or MAC CE. For example, when the first signaling indicates that the second access network node whose ID is S1 switches from the second state to the first state, the bit value corresponding to S1 in the first signaling is 0 or 1, for Indicates that the second access network node whose ID is S1 is in the first state. When the first signaling instructs the second access network node to switch from the second state to the first state, the first signaling carries a random access channel (RandomAccess Channel, RACH) resource configuration; the RACH The resource configuration is the RACH resource configuration dedicated to the random access procedure initiated by Spcel1 in the second access network node; optionally, the RACH resource configuration includes preamble code and RACHoccasion configuration. When the first signaling instructs the second access network node to switch from the first state to the second state or the third state, no RACH resource is configured. As shown in Figure 7, the configured RACH resources can correspond to the SN IDs of the second access network nodes that need RACH resources in order, such as one-to-one correspondence with RACHs in the order of SN IDs from small to large, or according to the order of SN IDs from large to large. The small order corresponds to RACH one by one; when more than two SNs are activated at the same time, S1 to S7 correspond one to one according to the order of SNID from small to large. During specific implementation, the state of the second access network node may also be controlled separately. At this time, the format of the MAC CE is as shown in FIG. 8; optionally, the MAC CE controls the second access network node to switch from the second state to the first state, or switch from the third state to the first state.

In some other embodiments, the terminal device determines the third state of the second access network node according to the first signaling. Optionally, the first signaling is PDCCH and/or MAC CE. When the MAC CE is used to indicate that the second access network node is in the second state or the third state, the first format diagram of the MAC CE is shown in FIG. 9; it is used to indicate that the second access network node is in the second state The MAC CEs in the state and the third state are two different MAC CEs. The two different MAC CEs have the same format and correspond to two different logical channels (Logical Channel, LC). The MAC CEs are identified by different LC IDs; for example For example, if the MAC CE is used to indicate that the second access network node is in the second state, the LCID corresponding to the MAC CE is 1; if the MAC CE is used to indicate that the second access network node is in the third state, Then the LC ID corresponding to the MAC CE is 0. Or, if the MAC CE is used to indicate that the second access network node is in the second state, the LC ID corresponding to the MAC CE is 0; if the MAC CE is used to indicate that the second access network node is in the third state, Then the LC ID corresponding to the MAC CE is 1; S1 to S7 correspond to each other according to the order of SN ID from small to large. Or, when the MAC CE is used to indicate that the second access network node is in the second state or the third state, the second format schematic diagram of the MAC CE is shown in FIG. 10; it is used to indicate that the second access network node is in the The MAC CEs in the second state and the third state are the same MAC CE and correspond to an LC ID; optionally, the value of Flag is 0 or 1; wherein, when the value of Flag is 0, it is used to indicate that the The second access network node is in the third state, when the value of Flag is 1, it is used to indicate that the second access network node is in the second state; or, when the value of Flag is 1, it is used to indicate that the The second access network node is in the third state, and when the value of Flag is 0, it is used to indicate that the second access network node is in the second state. S1 to S7 correspond to each other in ascending order of SN ID.

In still some embodiments, the terminal device determines the state of the second access network node according to a timer. For example, the terminal device determines that the second access network node switches from the first state to the second state based on a timer; in specific implementation, when the second access network node enters the first state, the terminal device starts the second state. A second timer, when the second timer expires, the terminal device confirms that the state of the second access network node needs to be updated from the first state to the second state. For another example, the terminal device determines that the second access network node switches from the first state to the third state based on the timer; in specific implementation, when the second access network node enters the first state, the terminal device starts the third state. A timer, when the third timer expires, the terminal device confirms that the state of the second access network node needs to be updated from the first state to the third state. As another example, the terminal device determines that the second access network node switches from the third state to the second state based on the timer; in specific implementation, when the second access network node enters the third state, the terminal device starts the fourth timer, when the fourth timer expires, the terminal device confirms that the state of the second access network node needs to be updated from the third state to the second state.

The conversion relationship between the three states of the second network node, as shown in Figure 11, the first state and the second state can be converted to each other, mutual conversion means that the first state can be switched to the second state, It can also be switched from the second state to the first state; the first state and the third state can be switched to each other, that is, the first state can be switched to the third state, and the third state can also be switched to the first state. The third state can only be switched to the second state, and the second state cannot be switched to the third state, that is, when the second access network node is in the second state, it cannot be switched to the third state.

In the embodiment of the present invention, the state of the second access network node can be initially configured through RRC signaling; for example, the state of the second access network node is initially configured as the first state or the second state through RRC signaling , or the third state. Or the second access network node is in the first state, or the second state, or the third state by default through RRC signaling. When the second access network node is in the second state, the path corresponding to the second access network node does not transmit and/or does not receive data.

In the embodiment of the present invention, when the terminal device indicates configuration of more than two second access network nodes through the first configuration information, the first configuration information is also used to indicate grouping information of the at least two second access network nodes. The at least second access network node is grouped based on at least one of the following: the radio frequency range where the second access network node is located, and whether the second access network node exists The first connection between. The grouping information includes at least one of: a group ID of the second access network node group, and a specific second access network node within the second access network node group. During specific implementation, a group ID is configured for each second access network node group, and each second access network node group is assigned a second access network node as a specific second access network node; optional Specifically, the specific second access network node is called a Special SN (SPSN), or a Primary SN (PSN). The specific second access network node establishes a control plane connection with the first access network node; optionally, the specific second access network node establishes an Xn or X2 connection with the first access network node The control plane connection is responsible for receiving core network configuration parameters forwarded from the first access network node, such as QoS parameters. Said specific second access network node is used for establishment (SRB3). The specific second access network node is used to manage the information of the second access network group; optionally, the specific second access network node is used to allocate the DRB ID of the second access network group , allocating a serving cell index (serving cell index), allocating LCID, measurement ID, measurement object ID, allocating measurement report ID, the specific second access network node is used to be in the second access network group, except for the A second access network node other than the specific second access network node generates keys and/or manages keys.

The status and management of the at least two second access network nodes have been described above, and the bearers of the at least two second access network nodes will be described below.

A schematic diagram of the bearer configuration of the first access network node and the second access network node, as shown in FIG. 12 , the first configuration information is also used to indicate that the split bearer includes at least three paths; wherein, the One of the at least three paths corresponds to the first access network node, and at least two of the at least three paths (legs) respectively correspond to different second access network nodes. Alternatively, the first configuration information is further used to indicate that the split bearer includes two paths; the two paths respectively correspond to two different second access network nodes. Alternatively, the first configuration information is also used to indicate the SCG bearer, and the PDCP entity and the radio link layer control protocol (Radio Link Control, RLC) entity of the SCG bearer correspond to different second access network nodes. Alternatively, the first configuration information is further used to indicate that the split bearer includes two paths, the first path of the two paths corresponds to the first access network node, and the second path of the two paths corresponds to A second access network node. Alternatively, the first configuration information is also used to indicate a master cell group (Master CellGroup, MCG) bearer, and the PDCP entity and the RLC entity carried by the MCG correspond to the first access network node. Alternatively, the first configuration information is also used to indicate the SCG bearer, and the PDCP entity and the RLC entity carried by the SCG are located in the same second access network node.

In the embodiment of the present invention, the path includes two states, namely the first state and the second state. When configuring more than two paths, configure a leg ID for each path. The leg ID can be configured starting from 1, and the leg ID can also be configured starting from 0. During specific implementation, the terminal device updates the state of the path corresponding to the second access network node according to the second signaling sent by the network device. Optionally, the second signaling includes at least one of the following: PDCCH and MACCE. The terminal device updates the state of the path to the first state or the second state by using the bit value corresponding to the path identifier in the second signaling. For example, when the bit value corresponding to the path ID carried by the second signaling is the first value, the terminal device updates the state of the path to the first state; the path ID carried by the second signaling corresponds to When the bit value of is the second value, the terminal device updates the state of the path to the second state. Optionally, the first value is 0, and the second value is 1. In FIG. 13 and FIG. 14 , L1 to L8 indicate that the index numbers of the path corresponding to the DRB ID are 1 to 8; the bit value corresponding to Li represents the state of the path. Optionally, the number of bits identifying the DRB ID can be flexibly configured; as shown in Figure 13, the number of bits identifying the DRB ID is 6 bits, and as shown in Figure 14, the number of bits identifying the DRB ID is 5 bits. In this way, the number of bits identifying the DRB ID can be flexibly configured according to needs, reducing signaling overhead.
