Description

Method and device for coordinating measurement configuration, network equipment and terminal

Technical Field

The embodiment of the application relates to the technical field of mobile communication, in particular to a method and a device for coordinating measurement configuration, network equipment and a terminal.

Background

In Multi-RAT dual connectivity (Multi-RAT Dual Connectivity, MR-DC), the primary Node (MN) and Secondary Node (SN) may be unsynchronized, so the MN may configure a system frame and radio frame timing offset (SFN and Frame Timing Difference, SFTD) measurement configuration for the terminal to make SFTD measurements and report SFTD measurements. The target node of the SFTD measurement configuration is a Primary cell (Primary Secondary cell, PScell) of an SN side.

During the PScell change on the SN side, the SN does not need to inform the MN about the change of the PScell if there is no change of the SN side key and no configuration of the secondary cell group (Secondary cell Group, SCG) bearer and secondary cell group split (SCG split) bearer terminated by the MN is involved. In this case, since the MN does not know which cell the PScell on the SN side changes to, the SFTD measurement configuration configured by the MN is not for the changed PScell, and if the SFTD measurement configuration exists before the PScell change, the SFTD measurement result obtained by the SFTD measurement performed by the terminal is not for the changed PScell.

With the pursuit of speed, delay, high speed mobility, energy efficiency and diversity and complexity of future life business, the third generation partnership project (3 ^rd Generation Partnership Project,3 GPP) international standards organization began developing 5G. The main application scenario of 5G is: enhanced mobile Ultra-wideband (enhanced Mobile Broadband, emmbb), low latency high reliability communication (URLLC), large-scale Machine-based communication (mctc).

On the one hand, embbs still target users to obtain multimedia content, services and data, and their demand is growing very rapidly. On the other hand, since an eMBB may be deployed in different scenarios, such as indoors, urban, rural, etc., its capabilities and requirements are also quite different, so that detailed analysis must be performed in connection with a specific deployment scenario, not in general. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical characteristics of mctc include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

At early deployment of NRs, full NR coverage is difficult to acquire, so typical network coverage is wide area LTE coverage and island coverage mode of NRs. And a large amount of LTE is deployed below 6GHz, and the frequency spectrum below 6GHz which can be used for 5G is few. NR must study spectral applications above 6GHz while high-band coverage is limited and signal fading is fast. Meanwhile, in order to protect the mobile operators from early investment in LTE, a working mode of close cooperation (tight interworking) between LTE and NR is proposed.

To enable 5G network deployment and commercial applications as soon as possible, 3GPP first completed the first 5G release, namely EN-DC (LTE-NR Dual Connectivity), before 2017, 12. In EN-DC, LTE base stations (enbs) as MNs, NR base stations (gnbs or EN-gnbs) as SNs, network deployment and networking of EN-DC is shown in fig. 2, wherein an evolved universal radio access network (Evolved Universal Terrestrial Radio Access Networ, E-UTRAN) represents an access network part, an evolved packet core network (Evolved Packet Core network, EPC) represents a core network part, the access network part being composed of at least one eNB (two enbs are illustrated in fig. 2) and at least one EN-gNB (two EN-gnbs are illustrated in fig. 2), wherein enbs as MNs, EN-gnbs as SNs, both MNs and SNs being connected to the EPC.

In the late stage of R15, other DC modes, namely NE-DC,5GC-EN-DC, NR DC, will be supported, both of which belong to MR-DC. For EN-DC, the core network to which the access network is connected is EPC, while the core network to which the other DC mode is connected is a 5G core network (5 GC). The technical solution of the embodiment of the present application may be applied to any of the above DC modes, but is not limited to the application.

Fig. 3 is a flowchart of a method for coordinating measurement configuration according to an embodiment of the present application, as shown in fig. 3, where the method for coordinating measurement configuration includes the following steps:

step 301: the auxiliary node receives capability information of a terminal sent by the main node, wherein the capability information of the terminal is used for indicating whether the terminal supports SFTD measurement or not.

The technical solution of the embodiment of the application is applied to a DC architecture, for example: EN-DC, NE-DC,5GC-EN-DC, NR DC, and the like. The access network part of the DC architecture consists of MN and SN, where the MN-side cell includes a Pcell and a Secondary cell (Scell), and the SN-side cell includes a PScell and a Scell.

In this embodiment of the present application, the terminal may be any device capable of communicating with a network, such as a mobile phone, a tablet computer, a notebook, and a vehicle-mounted terminal.

Considering that the MN node and the SN node may be unsynchronized, the MN may configure SFTD measurement configuration for the terminal, and the SFTD measurement result reported by the terminal may be applied to synchronization between the MN node and the SN node, and in one application, the SFTD measurement result may be used to assist in MN configuration measurement Gap configuration.

Specifically, in SFTD measurement configuration, one measurement is configured, which is identified by one measurement identification (id), each measurement being associated with a configuration of a measurement object and a configuration of a measurement report. In MR-DC, the measurement object is a PScell, and table 1 illustrates the configuration of measurement reports concerning the PScell:

TABLE 1

On the other hand, the configuration of the measurement object in the SFTD measurement configuration includes any one or more of frequency point information, PCI information, and serving cell index information of the measurement object, and in MR-DC, the measurement object is a PScell, and table 2 illustrates the configuration of the measurement object with respect to the PScell:

TABLE 2

The measurement object in table 2 is a PScell, and the configuration of the measurement object includes any one or more of frequency points, PCI and serving cell index information of the PScell. If the measurement object is neighbor cells (neighbor cells), the PCI list needs to be given in the cell ForWhichToportSFTD information field in the configuration of the measurement object; if PCI list is not configured in the configuration of the measurement object, the terminal measures SFTD measurement on the first 3 adjacent cells with the best signal quality.

In this embodiment of the present application, the master node obtains capability information of a terminal from the terminal or a core network, where the capability information of the terminal includes at least one of the following:

First capability information, wherein the first capability information is used for indicating whether the terminal supports SFTD measurement between a Pcell and a PScell; here, the measurement object refers to a PScell;

and second capability information, where the second capability information is used to indicate whether the terminal supports SFTD measurement between the Pcell and the neighboring cell. Then, the main node forwards the capability information of the terminal to the auxiliary node; here, the measurement object indicates a neighbor cell.

The master node forwards the capability information of the terminal to the auxiliary node, and the auxiliary node determines whether the terminal supports SFTD measurement or not based on the capability information of the terminal.

Step 302: under the condition that the terminal supports SFTD measurement, responding to PScell change of the auxiliary node, the auxiliary node sends a first notification message to the main node, wherein the first notification message is used for notifying the main node of PScell change and/or notifying attribute information of a new PScell after the main node change, and the attribute information comprises at least one of the following: frequency point information, PCI information and service cell index information.

In this embodiment of the present application, when the secondary node generates a PScell change, a radio resource control RRC reconfiguration message is sent to the terminal through the SRB3, so as to trigger the terminal to perform the PScell change; and after the terminal changes the PScell, the auxiliary node receives the RRC reconfiguration completion message sent by the terminal. And then, the auxiliary node judges that if the terminal supports SFTD measurement, a first notification message is sent to the main node, wherein the first notification message is used for notifying the main node that PScell is changed and/or notifying the attribute information of the new PScell after the change of the main node, and the attribute information comprises at least one of the following components: frequency point information, PCI information and service cell index information.

The following is an example of the technical solution of the embodiment of the present application with reference to fig. 4, as shown in fig. 4:

1. after the UE enters the RRC connected state, the MN acquires UE capability information from the UE.

Here, the MN obtains the UE capability information from the UE, but the MN is not limited to this and may obtain the UE capability information from the core network.

Specifically, the UE capability information includes capability information that the UE supports SFTD measurement, for example, the UE capability information includes an SFTD-MeasPScell information field and an SFTD-MeasNR-Cell information field, where the SFTD-MeasPScell information field is used to indicate whether the UE supports SFTD measurement between PCell and PScell; the SFTD-MeasNR-Cell information field is used to indicate whether the UE supports SFTD measurements between the PCell and the NR neighbor cells.

2. The MN forwards the UE capability information to the SN.

3. When the SN node triggers a PScell change, the SN sends an RRC reconfiguration (RRCRECONfigure) message to the UE through the SRB3, and triggers the UE to perform the PScell change.

Here, it should be noted that when the SN node triggers a PScell change, if there is no change in SN side key and no configuration of SCG bearer and SCG split bearer determined by the MN is involved, the SN does not need to coordinate with the MN.

4. After the UE has changed PScell, it sends an RRC reconfiguration complete (rrcrecon configuration complete) message to the SN.

Here, the UE performs the following operations after receiving the RRC reconfiguration message or after transmitting the RRC reconfiguration complete message:

1) If the UE has the SFTD measurement configuration for the original PScell before the change, the UE releases the SFTD measurement configuration of the original PScell before or after the PScell change is completed; or hanging the SFTD measurement configuration of the original PScell; or the SFTD measurement configuration of the original PScell is considered invalid; or consider the SFTD measurement delay timer to time out.

2) If the UE has a measurement result corresponding to the SFTD measurement configuration of the original PScell before modification, the UE does not report the measurement result or considers the measurement result invalid, and the measurement result is deleted.

5. The SN detects UE capability information, and if the UE supports SFTD measurement, the SN informs the MN of the change of the PScell and one or more of frequency point information, PCI information and service cell index information of the new PScell after the change.

The access network part of the DC architecture consists of MN and SN, where the MN-side cell includes Pcell and Scell, and the SN-side cell includes PScell and Scell.

Step 502: and the auxiliary node receives an RRC reconfiguration completion message sent by the terminal, wherein the RRC reconfiguration completion message carries first indication information.

Here, after the terminal changes the PScell, the auxiliary node receives the RRC reconfiguration complete message sent by the terminal.

In an embodiment, the first indication information is used for indicating the secondary node to notify the primary node that the PScell is changed and/or notify the primary node of the attribute information of the new PScell after the change.

In another embodiment, the first indication information is used for indicating that the terminal has an SFTD measurement configuration or an SFTD measurement configuration of an original PScell before modification.

Step 503: the auxiliary node sends a first notification message to the main node based on the first indication information, wherein the first notification message is used for notifying the main node that PScell is changed and/or notifying the attribute information of the new PScell after the change of the main node, and the attribute information comprises at least one of the following: frequency point information, PCI information and service cell index information.

Here, the MN acquires UE capability information from the UE after entering the RRC connected state. Here, the MN obtains the UE capability information from the UE, but the MN is not limited to this and may obtain the UE capability information from the core network.

2. When the SN node triggers a PScell change, the SN sends an RRC reconfiguration (RRCRECONfigure) message to the UE through the SRB3, and triggers the UE to perform the PScell change.

3. After the UE changes the PScell, an RRC reconfiguration complete (rrcrecon configuration complete) message is sent to the SN, where the RRC reconfiguration complete message carries the first indication information.

4. The SN informs the MN of one or more of frequency point information, PCI information and service cell index information of the new PScell after the change of the PScell according to the first indication information.
