MEASUREMENT GAP CONFIGURATION METHOD AND DEVICE

Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims a priority to the Chinese patent application No. 201810644192.8 filed in China on Jun. 21, 2018, a disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of communications technologies, and in particular, relates to a method and a device of configuring a measurement gap.

BACKGROUND

Referring to FIG. 1 and FIG. 2, in an Evolved-Universal Terrestrial Radio Access (E-UTRA)-New Radio (NR) Dual Connectivity (EN-DC) scenario, a Master Node (MN) is an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) node eNB (i.e., LTE eNB), and a secondary node is a Radio Access Network (RAN) node gNB in a 5G new radio system.

A measurement gap configuration method in an EN-DC scenario includes the following: 1) for UEs that do not support per Frequency Range (FR) gap but only per UE gap, an MN configures a gap and notifies the gap to a terminal (UE); 2) for UEs that support per FR gap, if a Per UE gap is configured, then an MN (LTE eNB) configures the gap and notifies the UE that the gap is a Per UE gap; if a Per FR gap is configured, then the MN is responsible for configuring a gap of a frequency range 1 (FR1, below 6 GHz) of the NR system, and notifying the UE that the gap is for the FR1. In addition, an SN is responsible for configuring a gap of a frequency range 2 (FR2, above 6 GHz) of the NR system and sending the gap to the UE.

For a configuration of the per UE gap, the SN needs to report, to the MN, frequency information of the FR1 and the FR2 to be measured, so that the MN may configure a suitable gap pattern.

For a configuration of the per FR gap, since the SN (gNB) node may need to perform an inter-frequency measurement of the FR1, the SN needs to report, to the MN, FR1 frequency information to be measured in order to facilitate the MN to configure a gap pattern of the FR1; similarly, the MN sends, to the SN, FR2 frequency information to be measured, so that the SN may configure a gap pattern of the FR2.

As shown in FIG. 3, and FIG. 4, in an NE-DC scenario, the MN is a gNB, and the secondary node is an eNB (i.e., LTE eNB). There is no clear solution for how to configure a measurement gap in the NE-DC scenario.

Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

The terms “first”, “second” and the like in the specification and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a particular order or chronological order. It is to be understood that the data so used may be interchangeable under appropriate circumstances, so that embodiments of the present application described herein may be implemented in a sequence other than those illustrated or described herein. In addition, such terms as “comprise”, “have” and any variants thereof are intended to cover non-exclusive inclusions, for example, a process, a method, a system, a product, or a device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products or devices. The term “and/or” in the specification and claims indicates at least one of objects connected by the term.

The technology described herein is not limited to a Long Time Evolution (LTE)/LTE-Advanced (LTE-A) system, and may also be used in various wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA) and other systems. The terms “system” and “network” are often used interchangeably. The CDMA systems may implement radio technologies such as CDMA2000 and Universal Terrestrial Radio Access (UTRA). The UTRA includes Wideband Code Division Multiple Access (WCDMA) and other CDMA variants. TDMA systems may implement radio technologies such as Global System for Mobile Communication (GSM). OFDM systems may implement radio technologies such as Ultra Mobile Broadband (UMB), Evolution-UTRA (E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, and Flash-OFDM. The UTRA and the E-UTRA are part of a Universal Mobile Telecommunications System (UMTS). The LTE and more advanced LTE (such as LTE-A) are new UMTS versions that use the E-UTRA. The UTRA, the E-UTRA, the UMTS, the LTE, the LTE-A, and the GSM are described in documents from an organization named “3rd Generation Partnership Project” (3GPP). The CDMA2000 and the UMB are described in documents from an organization named “3rd Generation Partnership Project 2” (3GPP2). The technologies described herein may be used for the systems and radio technologies mentioned above, as well as other systems and radio technologies. However, the following description describes an LTE system and an NR system for exemplary purposes, and LTE and NR terminology is used in most of the description below, although these technologies may also be applied to applications other than LTE and NR system applications.

The following description provides examples and does not limit the scope, applicability, or configuration set forth in the claims. Changes may be made to functions and arrangements of the discussed elements without departing from spirit and scope of the present disclosure. Various examples may omit, substitute, or add various procedures or components as appropriate. For example, the described method may be performed in an order different from that described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

In an NE-DC scenario, a master node is a radio access network (RAN) node gNB of a 5G system, and a secondary node is an E-UTRAN node eNB. The secondary node may configure a terminal to perform an inter-frequency measurement under an indication from the secondary node, that is, an inter-frequency measurement is performed within a LTE frequency range. The master node may configure the terminal to perform an inter-frequency measurement on NR frequencies (including FR1 and/or FR2), and may also configure the terminal to perform an inter-frequency measurement on LTE frequencies.

In the NE-DC scenario, since the MN becomes a gNB, a frequency point in an inter-frequency measurement of the gNB may include a LTE frequency point, an FR1 or FR2 frequency point of the NR system, while a frequency point of an inter-frequency measurement of the LTE may only be a LTE frequency point. Therefore, a possible measurement gap configuration scheme is that a MN (gNB) configures all measurement gap schemes, including a per UE measurement gap and a per FR measurement gap.

Table 1 shows applicable scenarios where 24 measurement gap patterns currently supported by the NR system are applied to. Regardless of configurations of the per UE gap or the per FR gap, in a dual-connection scenario, as long as LTE (E-UTRA) appears in a measurement purpose, a measurement gap pattern may only be configured with a pattern having IDs 0 to 3. Based on the above analysis, it may be seen that, for the SN, information of specific frequency points to be measured may not be notified to the MN, however, the MN is needed to be notified through a relevant indication, such as 1-bit indication information, that an inter-frequency measurement also needs to be performed on the SN side (i.e., LTE eNB). In this way, the MN may configure an appropriate measurement gap pattern for the terminal.

Referring to FIG. 5, an embodiment of the present disclosure provides a measurement gap configuration method applied to a secondary node in an NE-DC scenario. As shown in FIG. 5, the method includes Step 51.

Step 51: sending, by a secondary node, first indication information to a master node, wherein the first indication information is used to indicate that the secondary node needs to configure a terminal to perform an E-UTRAN inter-frequency measurement, or is used to request the master node to configure a measurement gap.

Here, the secondary node sends the first indication information to the master node in a case that the terminal needs to be configured to perform the E-UTRAN inter-frequency measurement and further a measurement gap needs to be configured for the terminal. In order to save a signaling overhead between nodes, the first indication information may be indicated by a predetermined 1-bit, for example, the first indication information indicates that the secondary node needs to configure the terminal to perform the E-UTRAN inter-frequency measurement in a case that a value of the 1-bit is 0, or, the first indication information indicates that the secondary node needs to configure the terminal to perform the E-UTRAN inter-frequency measurement in a case that a value of the 1-bit is 1.

Requesting the master node to configure a measurement gap may be caused by a condition that the secondary node needs to configure the terminal to perform the E-UTRAN inter-frequency measurement. Under the condition, the secondary node sends the first indication information to the master node, to request the master node to configure a measurement gap.

Specifically, the secondary node may send the first indication information to the master node through an inter-node interface Xn. The first indication information may be carried in an SCG configuration message (SCG-Config) or a CG configuration message (CG-Config) or other specifically defined messages for transmission.

Through the above step, in embodiments of the present disclosure, a master node may receive an indication from the secondary node in a case that the secondary node needs to configure a terminal to perform an LTE system inter-frequency measurement and further needs to configure a measurement gap for the terminal. In this way, when configuring a measurement gap for the terminal, the master node configures an appropriate measurement gap pattern according to the indication of the secondary node. For example, the measurement gap pattern is configured to be one of measurement gap patterns with IDs 0 to 3.

Optionally, in the method of the embodiment of the present disclosure, the secondary node may also send second indication information to the master node in a case that the secondary node does not need to configure the terminal to perform the Evolved-Universal Terrestrial Radio Access Network (E-UTRAN) inter-frequency measurement, wherein the second indication information is used to indicate that the secondary node does not need to configure the terminal to perform the E-UTRAN inter-frequency measurement, or is used for not requesting the master node to configure the measurement gap. Here, the second indication information may also be indicated by 1 bit of the first indication information, wherein, the second indication information indicates that the secondary node does not need to configure the terminal to perform the E-UTRAN inter-frequency measurement in a case that a value of the 1-bit is 1; or, the second indication information indicates that the secondary node does not need to configure the terminal to perform the E-UTRAN inter-frequency measurement in a case that a value of the 1-bit is 0.

Not requesting the master node to configure a measurement gap may be caused by a condition that the secondary node does not need to configure the terminal to perform the E-UTRAN inter-frequency measurement. Under the condition, the secondary node sends the second indication information to the master node, for not requesting the master node to configure a measurement gap.

Of course, in an embodiment of the present disclosure, the secondary node may also abstain from sending the second indication information to the master node in a case that the secondary node does not need to configure the terminal to perform the E-UTRAN inter-frequency measurement, that is, an indication about whether the secondary node needs to configure the E-UTRAN inter-frequency measurement is not sent. In this case, the master node may decide by itself how to configure a measurement gap pattern of the terminal. Through the above processing, a signaling overhead between nodes may be reduced.

A measurement gap configuration method in an embodiment of the present disclosure is described above from a secondary-node side, and a measurement gap configuration method will be further described from a master-node side with reference to FIG. 6.

Referring to FIG. 6, an embodiment of the present disclosure provides a measurement gap configuration method applied to a master node in a NE-DC scenario. The method specifically includes Step 61.

Step 61: receiving, by a master node, first indication information sent by a secondary node, wherein the first indication information is used to indicate that the secondary node needs to configure a terminal to perform an Evolved-Universal Terrestrial Radio Access Network (E-UTRAN) inter-frequency measurement, or is used to request the master node to configure a measurement gap.

Here, the first indication information is indicated by a predetermined 1-bit, wherein, the first indication information indicates that the secondary node needs to configure the terminal to perform the E-UTRAN inter-frequency measurement in a case that a value of the 1-bit is 0, or, the first indication information indicates that the secondary node needs to configure the terminal to perform the E-UTRAN inter-frequency measurement in a case that a value of the 1-bit is 1.

Through the above step, the master node may obtain the indication information of an inter-frequency measurement configuration of the secondary node, and accordingly configure an appropriate measurement gap pattern for the terminal. For example, the measurement gap pattern is configured to be one of measurement gap patterns with IDs 0 to 3.

Optionally, after Step 61, the method may also include: configuring, by the master node according to the first indication information, a measurement gap pattern of the terminal to be one of measurement gap patterns with identities 0 to 3.

Referring to FIG. 7, an embodiment of the present disclosure provides another measurement gap configuration method applied to a master node in a NE-DC scenario. The method specifically includes Step 71.

Step 71: receiving, by a master node, second indication information sent by a secondary node, wherein the second indication information is used to indicate that the secondary node does not need to configure a terminal to perform an E-UTRAN inter-frequency measurement, or is used for not requesting the master node to configure a measurement gap.

Here, the second indication information is indicated by the 1-bit, wherein, the second indication information indicates that the secondary node does not need to configure the terminal to perform the E-UTRAN inter-frequency measurement in a case that a value of the 1-bit is 1; or, the second indication information indicates that the secondary node does not need to configure the terminal to perform the E-UTRAN inter-frequency measurement in a case that a value of the 1-bit is 1.

Through the above steps, the master node may obtain the indication information of an inter-frequency measurement configuration of the secondary node, and accordingly configure an appropriate measurement gap pattern for the terminal. For example, the measurement gap pattern is configured to be one measurement gap pattern of measurement gap patterns with IDs 0 to 23.

Optionally, subsequent to Step 71, the method may also include: configuring, by the master node, a measurement gap pattern of the terminal according to whether the master node needs to configure the terminal to perform the E-UTRAN inter-frequency measurement, wherein, the measurement gap pattern of the terminal is configured to be one of measurement gap patterns with identities 0 to 3 in a case that the master node needs to configure the terminal to perform the E-UTRAN inter-frequency measurement, and further needs to configure the measure gap for the terminal.
