Detailed ways

Before describing the technical solutions of the embodiments of the present invention in detail, a configuration solution of a measurement interval (gap) in a dual connectivity scenario is briefly described first.

The data transmission scheme of the embodiment of the present invention is applied to DC scenarios, including E-UTRA and NR dual connectivity (EN-DC, E-UTRA-NR Dual Connectivity), next-generation E-UTRA and NR dual connectivity (NG-EN DC , NG-RAN E-UTRA-NRDual Connectivity), NR and E-UTRA dual connectivity (NE-DC, NR-E-UTRA Dual Connectivity) and NR dual connectivity (NR-DC, NR Dual Connectivity). Among them, E-UTRA means Evolved Universal Terrestrial Radio Access (Evolved Universal Terrestrial Radio Access), which means Long Term Evolution (LTE, Long Term Evolution) system or 4G system; NR means New Radio Access (New Radio Access), means NR system or 5G system.

Among them, Fig. 1a and Fig. 1b are schematic diagrams of an application scenario of the data transmission method according to an embodiment of the present invention; Fig. 1a and Fig. 1b are specifically EN-DC scenarios. In this application scenario, user equipment (UE, User Equipment) respectively Connect with the evolved base station (eNB, Evolved Node B) of the LTE system and the base station (gNB) of the NR system; the difference lies in whether the user plane of the gNB is connected to the evolved packet (EPC, Evolved Packet Core) network. For the EN-DC scenario shown in Figure 1a, the user plane offload is only performed by the eNB, and the user plane of the gNB is connected to the eNB; for the EN-DC scenario shown in Figure 1b, the gNB is directly connected to the EPC network, which is performed by the EPC network Business diversion. In this scenario, the LTE eNB acts as a master node (MN, Master Node), and the gNB acts as a secondary node (SN, Secondary Node).

For NG-EN DC scenarios, NE-DC scenarios, and NR-DC scenarios, refer to the existing dual-connection connection methods.

It can be understood that the applicable scenarios of the embodiments of the present invention include the first scenario and the second scenario; wherein, the first scenario is a scenario based on a 5G core network where the MN and the SN are connected, and there is a control plane between the MN and the 5G core network Connection and user plane connection, there is only a user plane connection between the SN and the 5G core network. The gNB can serve as the MN, and the gNB or eNB can serve as the SN node. The second scenario is an EPC-based scenario where the MN and the SN are connected. A control plane connection and a user plane connection exist between the MN and the EPC core network, and a user plane connection exists between the SN and the EPC core network. The eNB may serve as the MN, and both the eNB and the gNB may serve as the SN.

The measurement interval (gap) configuration method for the above scenario includes the measurement gap configuration method according to the UE, that is, the measurement gap is configured for different UEs, which is recorded as the per UE measurement gap, and the measurement gap configuration according to the spectrum range (FR, FrequencyRange) The mode, that is, the configurable measurement interval for different RFs of the same UE, is recorded as the per FR measurement interval.

The interval configuration of EN-DC and NG-EN DC scenarios includes the following situations:

For UEs that only support per UE measurement intervals and do not support per FR measurement intervals, the MN configures the gap type (gap type) and gap pattern (gap pattern), and notifies the UE; the SN needs to configure the FR1 and FR2 frequency The point information is reported to the MN so that the MN can configure a suitable gap pattern;

For a UE that supports per FR measurement intervals, the gap pattern configured by the MN decides whether the gap pattern is a per UE measurement interval or a per FR measurement interval, that is, the MN selects the UE's interval configuration method;

If the MN decides to configure the Per FR measurement interval, the MN is responsible for configuring the measurement interval corresponding to FR1 (for example, below 6 GHz), and notifies the UE whether the measurement interval corresponds to FR1 in the per FR measurement interval configuration mode or corresponds to the per UE measurement interval Configuration mode: SN is responsible for configuring the measurement interval corresponding to FR2 (for example, above 6 GHz), and notifying UE. To this end, the SN reports the FR1 frequency point information to be measured to the MN, and the MN sends the FR2 frequency point information to be measured to the SN;

If the MN decides to configure the per UE measurement interval, the MN (ie LTE eNB) configures the corresponding measurement interval for the UE, and notifies the UE that the measurement interval corresponds to the per UE measurement interval configuration method; the SN needs to set the FR1 to be measured , FR2 frequency point information is reported to the MN, so that the MN configures a suitable gap pattern for the UE.

For the gap configuration in the NE-DC scenario, regardless of the per UE measurement gap or per FR measurement gap configuration mode, the MN configures the gap type and gap pattern; the SN only needs to inform the MN whether the measurement gap is required for its own measurement.

For the gap configuration in the NR-DC scenario, regardless of the per UE measurement interval or per FR measurement interval configuration mode, the gap type and gap pattern are configured by the MN; the SN needs to report the FR1 and FR2 frequency point information to be measured to the MN, so that The MN configures a suitable gap pattern for the UE.

To sum up, the per UE measurement interval is always configured by the MN, and the SN informs the MN of the frequency point information it needs to measure; the configuration method of the per FR measurement interval is only in the EN-DC scenario, and the FR2 measurement interval is configured by the SN configuration, and other scenarios are configured by the MN.

Based on the above description, regardless of the per UE measurement interval or per FR measurement interval configuration scheme, the MN or SN only needs to inform the node that configures the corresponding gap pattern of the frequency point information that it wants to measure; even, in the NE-DC scenario , the SN only needs to inform the MN that inter-frequency measurement or measurement interval is required. In fact, the configuration of the gap pattern is also related to the working frequency of the MN or SN, including the frequency information of the primary cell (Pcell) and the secondary cell (Scell).

For example, for the measurement interval configuration per UE in the NR-DC scenario, when the MN needs to measure a certain inter-frequency point f1, since there is no f1 in the MN's working frequency point, the MN will consider that the UE configuration measurement interval needs to be measured; and In fact, a certain Scell of the SN works on the frequency point f1, and the UE does not need to configure a measurement interval when measuring the frequency point f1. If the MN can know the working frequency of the Scell related to the SN, it can configure the measurement interval more accurately, and at the same time make reasonable use of the inter-frequency measurement capability of the terminal. However, at present, the SN only sends the frequency point range of the serving cell to the MN, but does not have a specific working frequency point. Therefore, the MN cannot configure a reasonable measurement interval, and it is very likely that the measurement interval is configured instead of the original measurement interval.

Based on the above application scenarios and practical problems, the following embodiments of the present invention are proposed.

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
