Technical Field

[0002] With people's pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of business in future life.

[0003] To this end, the 3rd Generation Partnership Project (3GPP) international standards organization began to develop the fifth generation of mobile communication technology (5-Generation, 5G). The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low Latency Communication (URLLC), and massive machine type of communication (mMTC).

[0004] In the early deployment of New Radio (NR), complete NR coverage was difficult to obtain, so the typical network coverage was wide-area Long Term Evolution (LTE) coverage and NR island coverage mode. And because a large number of LTEs are deployed below 6 GHz, there is little spectrum below 6 GHz available for 5G. Therefore, NR must study spectrum applications above 6 GHz, but high-frequency bands have limited coverage and fast signal fading.

[0005] In the prior art, in order to protect the initial investment of mobile operators in LTE, a tight interworking working mode between LTE and NR is proposed. Specifically, the bandwidth combination is used to support LTE-NR dual connection (DC) data transmission to improve system throughput.

[0006] However, for the above-mentioned tight interworking working mode between LTE and NR, the measurement initiator (such as LTE) does not know whether the measured end (such as NR) is configured with a measurement interval for the terminal device, which may cause the measurement initiator to affect the system operation when measuring the measured end.

[0068] Figure 1 It is a schematic diagram of an application scenario of an embodiment of the present invention.

[0069] like Figure 1 As shown, the terminal device 110 is connected to a first network device 130 under a first communication system and a second network device 120 under a second communication system. For example, the first network device 130 is a network device under Long Term Evolution (LTE), and the second network device 120 is a network device under New Radio (NR).

[0070] The first network device 130 and the second network device 120 may include multiple cells.

[0071] However, before the terminal device 110 performs cell switching, the terminal device 110 normally measures the power (signal quality) of the target cell and reports it to the first network device 130, and the first network device 130 decides whether to allow the terminal device 110 to switch to the target cell.

[0072] It can be found that if the target cell and the current cell have the same frequency (same-frequency measurement), the terminal device 110 can easily measure the signal quality of the target cell; but if they have different frequencies (different-frequency measurement), it is difficult for the terminal device 110 to measure the signal quality of the target cell.

[0073] From a logical point of view, the simplest solution for inter-frequency measurement is to implement two sets of radio frequency (RF) transceivers on the UE. However, there are practical difficulties in the dual RF transceiver solution. One problem is that the cost is too high due to the additional cost required to implement the additional transceiver. Another problem is the possible interference between the current frequency and the target frequency, especially when the two are close, especially for dual-link scenarios.

[0074] In order to solve the above problem, in an embodiment of the present invention, a method for a network device to configure a measurement interval for a terminal device is proposed. In a dual-link scenario, a measurement gap is configured for the terminal device 110. Thus, the measurement gap configured for the terminal device 110 can be used for heterofrequency measurement or intra-frequency measurement. Specifically, the terminal device 110 can switch to a target cell and perform signal quality measurement, and then switch back to the current cell (continue normal transmission and reception).

[0075] In other words, the measurement interval configured by the terminal device (current cell) is neither used for sending data nor for receiving data.

[0076] Furthermore, in the embodiment of the present invention, when the first network device 130 requires the terminal device 110 to perform frequency measurement on the second network device 120, it is possible that the terminal device 110 requires a group of gap values, that is, the network device requires a gap.

[0077] For example, the radio frequency (FR1) supporting LTE and the FR2 supporting NR are independent. That is, the terminal device 110 works with the first network device 130 and the second network device 110 at different frequencies, respectively, so that the gap configured by the terminal device 110 for FR1 and the gap configured by the terminal device 110 for FR2 are independent.

[0078] At this time, in the LTE-NR scenario, for the NR side, which frequencies are configured as secondary cells (SCell) is determined by the second network device 120. Therefore, if the first network device 130 wants to measure the frequency FR2 where the second network device 120 is located through the terminal device 110, the first network device 130 does not know whether the second network device 120 needs to configure a gap. This may cause the measurement initiator to affect the system operation when measuring the measured end.

[0079] For example, if the second network device 120 also configures the terminal device 110 to work in a FR2 that is not equal to FR1, and the second network device 120 does not configure a gap for the terminal 110, the terminal device 110 needs to configure a gap.

[0080] For another example, if the second network device 120 has already configured a gap for the terminal device 110 at this time, the terminal device 110 does not need to reconfigure the gap.

[0081] For another example, if the second network device 120 also configures the terminal device 110 to work at FR2 equal to FR1, the terminal device 110 does not need to configure a gap.

[0082] In order to solve the above problem, an embodiment of the present invention provides a method for configuring a measurement interval. When the first network device 130 requires the terminal device 110 to measure the frequency of the second network device 120, the first network device 130 can be informed that the second network device 120 configures the measurement interval for the terminal device 110, thereby avoiding the possible impact of the measurement initiator on the system operation when measuring the measured end.

[0083] It should be understood that Figure 1 This is an example of the scenario of the embodiment of the present invention, and the embodiment of the present invention is not limited to Figure 1 shown.

[0084] For example, the communication system to which the embodiment of the present invention is applicable may include at least a plurality of network devices under the first communication system and / or a plurality of network devices under the second communication system.

[0085] For another example, the first communication system and the second communication system in the embodiment of the present invention are different, but the specific categories of the first communication system and the second communication system are not limited. For example, the first communication system and the second communication system can be various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), etc.

[0086] Furthermore, the present invention describes various embodiments in conjunction with the network devices (the first to fourth network devices) and the terminal devices.

[0087] The network device may refer to any entity on the network side that is used to send or receive signals. For example, it may be a user equipment of machine type communication (MTC), a base transceiver station (BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolutionary Node B (eNB or eNodeB) in LTE, a base station device in a 5G network, etc.

[0088] The terminal device 110 may be any terminal device. Specifically, the terminal device may communicate with one or more core networks via a radio access network (RAN), and may also be referred to as an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. For example, it may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, and a terminal device in a 5G network.

[0089] Figure 2 is a schematic flow chart of a configuration measurement detection method according to an embodiment of the present invention.

[0090] like Figure 2 As shown, the method includes:

[0091] 210. The first network device generates indication information.

[0092] 220. The first network device sends the indication information to the terminal device.

[0093] 230. The terminal device measures the signal quality according to the indication information.

[0094] Specifically, when the first network device determines that the terminal device needs to measure the first frequency where the second network device is located, it generates indication information, where the indication information is used to instruct the terminal device to measure the first frequency; the first network device sends the indication information to the terminal device. Correspondingly, for the terminal device, the terminal device receives the indication information sent by the first network device; and measures the first frequency according to the indication information.

[0095] It should be noted that, in the embodiment of the present invention, the first network device may instruct the terminal device to measure the first frequency without knowing whether the second network device needs to configure a measurement interval for the terminal device.

[0096] That is to say, after receiving the indication information, the terminal device can determine whether the second network device needs to allocate a measurement interval when measuring the first frequency.

[0097] Specifically, if the second network device does not configure a measurement interval for the terminal device, and the second frequency is different from the first frequency at which the terminal device operates, in this case the terminal device can request the first network device or the second network device to configure a measurement interval for measuring the first frequency.

[0098] It should be understood that the first frequency in the embodiment of the present invention may include the central frequency point and / or bandwidth of the second network device, and the embodiment of the present invention does not specifically limit this.

[0099] The following describes a method for implementing the terminal device obtaining the measurement interval in the case where the terminal device needs the second network device to allocate the measurement interval.

[0100] In one embodiment, the terminal device may send a first message to the first network device, the first message including a message for requesting the first network device to configure a first measurement interval for the terminal device, so that the first network device sends a second message to the second network device according to the first message, the second message including a message for requesting the second network device to configure the first measurement interval for the terminal device; the terminal device receives a response message to the first message sent by the first network device or the second network device, and the response message to the first message includes the first measurement interval.

[0101] For the first network device, the first network device receives a first message sent by the terminal device; and the first network device sends a second message to the second network device according to the first message.

[0102] In short, the terminal device may first request the first measurement interval from the first network device, and then the first network device may request the first measurement interval from the second network device. Thus, the first network device or the second network device sends a response message carrying the first measurement interval to the terminal device.

[0103] Specifically, the first network device receives a response message to the second message sent by the second network device, and the response message to the second message includes the first measurement interval; the first network device sends a response message to the first message to the terminal device based on the response message to the second message, and the response message to the first message includes the first measurement interval, so that the terminal device measures the first frequency according to the first measurement interval.

[0104] In another embodiment, the terminal device sends a fourth message to the second network device, and the fourth message includes a message for requesting the second network device to configure a first measurement interval for the terminal device; the terminal device receives a response message to the fourth message sent by the first network device or the second network device, and the response message to the fourth message includes the first measurement interval.

[0105] In other words, after receiving the fourth message sent by the terminal device, the second network device sends a response message of the fourth message to the terminal device.

[0106] It should be understood that in the embodiment of the present invention, the first network device may directly instruct the terminal device to measure the first frequency, or may directly instruct the terminal device to measure the first frequency according to a measurement interval.

[0107] The following is an implementation manner in which the first network device instructs the terminal device to measure the first frequency where the first network device is located when knowing whether the second network device needs to allocate a measurement interval for the terminal device.

[0108] Specifically, when the first network device determines that the terminal device needs to measure the first frequency where the second network device is located, it generates indication information, and the indication information is more specifically used to instruct the terminal device to measure the first frequency according to the second measurement interval.

[0109] In one embodiment, the first network device may determine whether the second network device needs to allocate a measurement interval for the terminal device before generating the indication information.

[0110] Specifically, Figure 3 As shown, the process of the first network device determining whether the second network device needs to allocate a measurement interval for the terminal device includes:

[0111] 201, the first network device sends a third message to the second network device;

[0112] 202. The second network device sends a response message of the third message to the first network device.

[0113] 203. The first network device generates indication information according to the response message of the third message.

[0114] Specifically, the first network device may send a third message to the second network device before generating the indication information, and the third message includes a message for requesting the second network device to configure the second measurement interval for the terminal device; the first network device receives a response message to the third message sent by the second network device, and the response message to the third message includes the configuration result of the second measurement interval and / or the second measurement interval; and then, the first network device may generate the indication information based on the response message to the third message.

[0115] It should be understood that the second measurement interval is a measurement interval configured by the second network device for the terminal device before or after receiving the third message. This embodiment of the present invention does not specifically limit this.

[0116] That is to say, if the second network device has configured the second measurement interval for the terminal device, the first network device can instruct the terminal to use the existing second measurement interval to measure the first frequency; if the second network device has not configured the second measurement interval for the terminal device, the second network device configures the second measurement interval for the terminal device, and the first network device or the second network device instructs the terminal device to use the configured second measurement interval to measure the first frequency.

[0117] In addition, an embodiment of the present invention further provides a network device, such as Figure 4 As shown, the network device 300 includes:

[0118] The processing unit 310 is configured to generate indication information when determining that the terminal device needs to measure the first frequency where the second network device is located, where the indication information is used to instruct the terminal device to measure the first frequency;

[0120] Optionally, the transceiver unit 320 is further configured to:

[0121] Receive a first message sent by the terminal device, the first message including a message for requesting the network device to configure a first measurement interval for the terminal device, the first measurement interval being used for the terminal device to measure the first frequency; send a second message to the second network device according to the first message, the second message including a message for requesting the second network device to configure the first measurement interval for the terminal device.

[0125] Optionally, the transceiver unit 320 is further configured to:

[0127] The indication information is generated according to a response message to the third message.

[0128] Optionally, the second measurement interval is a measurement interval configured by the second network device for the terminal device before or after receiving the third message.

[0132] A response message to the third message is sent to the first network device, wherein the response message to the third message includes the configuration result of the second measurement interval and / or the second measurement interval, so that the first network device generates indication information according to the response message to the third message, and the indication information is used to instruct the terminal device to measure the first frequency where the second network device is located according to the second measurement interval.

[0133] Optionally, the second measurement interval is a measurement interval configured by the second network device for the terminal device before or after receiving the third message.
