[0002] The network side can configure one or more dedicated bandwidth parts (Band Width Part, BWP) of the serving cell for the terminal device. For each serving cell, one or more dedicated BWPs can be configured for the serving cell, and only one dedicated BWP can be activated at the same time. For a serving cell, if the serving cell is configured with multiple dedicated BWPs, the activated dedicated BWP can be switched between multiple dedicated BWPs.

[0003] However, different dedicated BWPs activated in the serving cell may change whether the measurement interval is required for a certain frequency point. In other words, the number of frequencies measured using a certain measurement interval may also change. Therefore, configuring the measurement interval according to the granularity of the user equipment (UE) will result in poor flexibility. How to configure the measurement interval and how to use the measurement interval need to be further improved. Summary of the invention

[0037] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, 5G communication system or future communication system, etc.

[0039] For example, the communication system 100 used in the embodiment of the present application is as follows: Figure 1 As shown. The communication system 100 may include a network device 110, which may be a device that communicates with a terminal 120 (or referred to as a communication terminal, terminal). The network device 110 may provide communication coverage for a specific geographical area, and may communicate with terminals located within the coverage area. Optionally, the network device 110 may be an evolved base station (eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN), or the network device may be a mobile switching center, a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, a network-side device in a 5G network, or a network device in a future communication system, etc.

[0040] The communication system 100 also includes at least one terminal 120 located within the coverage of the network device 110. As used herein, "terminal" includes but is not limited to connecting via a wired line, such as via a Public Switched Telephone Networks (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection; and / or another data connection / network; and / or via a wireless interface, such as, for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter; and / or another terminal configured to receive / send communication signals; and / or an Internet of Things (IoT) device. A terminal configured to communicate via a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; Personal Communications System (PCS) terminals that may combine cellular radiotelephones with data processing, fax, and data communications capabilities; PDAs that may include radiotelephones, pagers, Internet / Intranet access, Web browsers, notepads, calendars, and / or Global Positioning System (GPS) receivers; and conventional laptop and / or palmtop receivers or other electronic devices that include radiotelephone transceivers. A terminal may refer to an access terminal, User Equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device.

[0041] Optionally, the terminals 120 may perform device-to-device (D2D) communication.

[0042] Optionally, the 5G communication system or 5G network may also be referred to as a New Radio (NR) system or NR network.

[0043] Figure 1 One network device and two terminals are shown exemplarily. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminals within its coverage area, which is not limited in the embodiments of the present application.

[0044] Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0045] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be referred to as a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal 120 with communication functions. The network device 110 and the terminal 120 may be the specific devices described above and will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0046] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0047] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

[0048] As people pursue higher speed, lower latency, high-speed mobility, and higher energy efficiency, as well as the diversity and complexity of services in future life, the 3rd Generation Partnership Project (3GPP) international standard organization has begun to develop 5G. The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra Reliable Low Latency Communication (URLLC), and massive Machine Type Communication (mMTC).

[0049] On the one hand, eMBB still aims at users to obtain 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, in urban areas, and in rural areas, its 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, power automation, remote medical operations (surgery), traffic safety, etc. Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of modules, etc.

[0050] In the early days of NR deployment, complete NR coverage was difficult to obtain, so the typical network coverage was wide-area LTE coverage and NR island coverage mode. In addition, a large number of LTEs are deployed below 6GHz, and there is little spectrum below 6GHz available for 5G. Therefore, NR must study spectrum applications above 6GHz, but high-frequency bands have limited coverage and fast signal fading. At the same time, in order to protect mobile operators' early investments in LTE, a tight interworking working mode between LTE and NR was proposed.

[0051] In order to realize 5G network deployment and commercial applications as soon as possible, 3GPP first completed the first 5G version, namely EN-DC (LTE-NR Dual Connectivity). In EN-DC, the LTE base station (eNB) serves as the master node (Master Node, MN), and the NR base station (gNB or en-gNB) serves as the secondary node (Secondary Node, SN), connected to the EPC core network. In the later stage of R15, other DC modes will be supported, namely NE-DC, 5GC-EN-DC, and NR DC. In NE-DC, the NR base station serves as the MN and the eLTE base station serves as the SN, connected to the 5GC core network. In 5GC-EN-DC, the eLTE base station serves as the MN and the NR base station serves as the SN, connected to the 5GC core network. In NR DC, the NR base station serves as the MN and the NR base station serves as the SN, connected to the 5GC core network.

[0052] NR can also be deployed independently. NR will be deployed on high frequencies in the future. In order to improve coverage, in 5G, a beam sweeping mechanism is introduced to meet coverage requirements (exchanging space for coverage and time for space). Figure 2After the introduction of beam sweeping, synchronization signals need to be sent in each beam direction. The synchronization signals of 5G are given in the form of synchronization signal blocks (SS / PBCH blocks, SSB), including primary synchronization signals (Primary Synchronisation Signal, PSS), secondary synchronization signals (Secondary Synchronisation Signal, SSS), and physical broadcast channels (Physical Broadcast Channel, PBCH), as shown in Figure 1. Figure 3 The 5G synchronization signal appears periodically in the time domain in the form of a synchronization signal burst set (SSburst set), as shown in Figure 4 shown.

[0053] The actual number of beams transmitted by each cell is determined by the network configuration, but the frequency of the cell determines the maximum number of beams that can be configured, as shown in Table 1 below.

[0054] Frequency range L (maximum number of beams) Greater than 3(2.4)GHz 4 3(2.4)GHz-6GHz 8 6GHz-52.6GHz 64

[0055] Table 1

[0056] In the Radio Resource Management (RRM) measurement, the measurement signal can be SSB measurement, that is, measuring the SSS signal in the SSB or the demodulation reference signal (DMRS) signal of the PBCH to obtain the beam measurement result and the cell measurement result. In addition, the terminal device in the Radio Resource Control (RRC) connection state can also configure the Channel Status Indicator Reference Signal (CSI-RS) as the reference signal for cell measurement.

[0057] For SSB-based measurements, the actual transmission position of SSB in each cell may be different, and the SS burst set period may also be different. Therefore, in order to save energy during the measurement process, the network side configures the SSB measurement timing configuration (SS / PBCH block measurement timing configuration, SMTC) for the terminal device. The terminal device only needs to perform measurements within the SMTC window, such as Figure 5 shown.

[0058] Since the position of the SSB actually transmitted in each cell may be different, in order to enable the terminal device to find the position of the actually transmitted SSB as soon as possible, the network side will also configure the terminal device with the actual SSB transmission position measured by the UE, such as the union of the actual SSB transmission positions of all measured cells. For example, at 3-6GHz, the network side indicates the bitmap: 10100110, which notifies the terminal device to measure only the SSBs with SSB index (SSBindex) of 0, 2, 5, and 6 among the candidate positions of the 8 SSBs.

[0059] Radio Resource Management (RRM) measurements are divided into two types: intra-frequency measurements and inter-frequency measurements. For inter-frequency measurements, measurement interval configuration may be required. As shown in Table 2 below, the measurement interval configuration includes the following information: measurement interval period (MGRP), measurement interval offset (GapOffset), measurement interval length (MGL), timing reference (MGTA), etc.

[0060]

[0061] Table 2

[0062] The various information in the measurement interval configuration can be referred to Figure 6 As shown, MGRP represents the period of measurement interval repetition, GapOffset represents the offset of the starting position of the measurement interval relative to the starting position of an MGRP, MGL represents the duration of the measurement interval, and MGTA is used to determine the timing of the measurement interval.

[0063] For a terminal device in the RRC connected state, if it is to perform inter-frequency or inter-system measurements, the network side needs to configure a measurement interval, during which the terminal device stops measuring all services and service cells. In addition, intra-frequency measurements may also require a measurement interval.

[0064] NR supports measurement intervals configured at UE granularity (per UE) and measurement intervals configured at FR granularity (per FR), where the relevant configuration of the measurement interval configured at per UE may also be referred to as per-UE gap configuration, and the relevant configuration of the measurement interval configured at per FR may also be referred to as per-FR gap configuration.

[0065] For per-UE gap configuration:

[0066] MN determines the per UE gap configuration and the related gap sharing configuration. Further, MN sends the per UE gap configuration to the terminal device, and MN also notifies SN about the per UE gap configuration and gap purpose (such as per-UE). Further, SN notifies MN about the FR1 frequency list and FR2 frequency list to be configured by SN as gap configuration auxiliary information.

[0067] For per-FR gap configuration:

[0068] 1) For NG-DC or EN-DC: MN determines the FR1 gap configuration and related gap sharing configuration; SN determines the FR2 gap configuration and related gap sharing configuration. Further, MN will configure the per FR1 gap to the terminal device, and MN will also notify SN about the per FR1 gap configuration and gap purpose (such as per-FR1). Further, MN notifies SN about the FR2 frequency list to be configured by MN as gap configuration auxiliary information, and SN notifies MN about the FR1 frequency list to be configured by SN as gap configuration auxiliary information.

[0069] 2) For NE-DC and NR-DC, MN determines the FR1 gap configuration and related gap sharing configuration, as well as the FR2 gap configuration and related gap sharing. Further, for NE-DC, MN notifies SN about the per FR1 gap configuration, and SN provides gap demand request to MN, but does not require any frequency list; for NR-DC, MN notifies SN about the per FR1 gap configuration, per FR2 gap configuration and gap purpose, and SN can indicate to MN about the FR1 frequency list and FR2 frequency list to be configured by SN.

[0070] There are many types of measurement intervals. The following Table 3 shows the configuration of 24 interval patterns. Different interval patterns correspond to different measurement periods (MGRP) and measurement durations (MGL). Some interval patterns are used for FR1 frequency point measurements, and some interval patterns are used for FR2 frequency point measurements.

[0071]

[0072] Table 3

[0073] In NR, the measurement interval is configured to the terminal device through RRC dedicated signaling and is a per UE configuration parameter.

[0074] In 5G, the maximum channel bandwidth can be 400MHZ (called wideband carrier), which is very large compared to the maximum 20M bandwidth of LTE. If the terminal device keeps working on the wideband carrier, the power consumption of the terminal device is very large. Therefore, it is recommended that the radio frequency (RF) bandwidth of the terminal device can be adjusted according to the actual throughput of the terminal device. To this end, the concept of BWP is introduced, and the motivation of BWP is to optimize the power consumption of the terminal device. For example, if the rate of the terminal device is very low, a smaller BWP can be configured for the terminal device. If the rate requirement of the terminal device is very high, a larger BWP can be configured for the terminal device. If the terminal device supports high speed, or works in carrier aggregation (CA) mode, multiple BWPs can be configured for the terminal device. Another purpose of BWP is to trigger the coexistence of multiple basic parameter sets (numerology) in a cell, for example, BWP1 corresponds to numerology1, and BWP2 corresponds to numerology2.

[0075] Terminal devices in idle or inactive states reside on the initial BWP. The initial BWP is visible to terminal devices in idle or inactive states. Terminal devices can obtain information such as the Master Information Block (MIB), Remaining Minimum System Information (RMSI), Other System Information (OSI) and paging from the initial BWP.

[0076] For terminal devices in the RRC connected state, up to 4 uplink BWPs and up to 4 downlink BWPs can be configured for a terminal through RRC dedicated signaling, but only one uplink BWP and downlink BWP can be activated at the same time. In the RRC dedicated signaling, the first activated BWP among the configured BWPs can be indicated. At the same time, while the terminal device is in the RRC connected state, it can also switch between different BWPs through downlink control information (Downlink Control Information, DCI). When a carrier in an inactive state enters an activated state, the first activated BWP is the first activated BWP configured in the RRC dedicated signaling.

[0077] The configuration of BWP is based on the granularity of the service cell. The network side can configure one or more dedicated BWPs for the service cell for the terminal device. For each service cell, one or more dedicated BWPs can be configured for the service cell (such as up to 4 uplink BWPs and up to 4 downlink BWPs). Only one dedicated BWP can be activated at the same time (such as one uplink BWP and / or one downlink BWP is activated). For a service cell, if the service cell is configured with multiple dedicated BWPs, the activated dedicated BWP can be switched between multiple dedicated BWPs.

[0078] However, different dedicated BWPs activated in the serving cell may change whether the measurement interval is required for a certain frequency point. In other words, the number of frequencies measured using a certain measurement interval may also change. Therefore, configuring the measurement interval according to the UE granularity will result in poor flexibility. How to configure the measurement interval and how to use the measurement interval need to be further improved.

[0079] To this end, the following technical solution of the embodiment of the present application is proposed. In the technical solution of the embodiment of the present application, the measurement interval is configured according to the BWP granularity, so that the measurement interval used can be changed according to the current wireless resource usage status of the terminal device (that is, the BWP currently located by the terminal device).

[0080] It should be noted that the network device in the embodiment of the present application may be a base station, but is not limited to this. The network device may also be other devices with control functions.

[0081] Figure 7 is a flow chart of a method for determining a measurement interval provided in an embodiment of the present application, such as Figure 7 As shown, the method for determining the measurement interval includes the following steps:

[0082] Step 701: The terminal device determines that a switch from a source BWP to a target BWP is triggered, the source BWP switch is associated with a first measurement interval configuration, and the target BWP is associated with a second measurement interval configuration.

[0083] In an embodiment of the present application, the network device may pre-configure at least one measurement interval configuration for the terminal device. Specifically, the terminal device receives first configuration information sent by the network device, the first configuration information includes at least one measurement interval configuration, and each measurement interval configuration in the at least one measurement interval configuration is associated with a measurement interval index. In some optional implementations, the first configuration information is carried in RRC dedicated signaling.

[0084] In some optional implementations, each measurement interval configuration is associated with a priority, which may also be referred to as a measurement interval usage priority, and the priority is used to determine whether the measurement interval configuration is preferentially activated or enabled.

[0085] For example: the network device configures at least one measurement interval configuration to the terminal device through RRC dedicated signaling. Each measurement interval configuration is used to determine a type of measurement interval (or interval pattern), and each measurement interval configuration is associated with a measurement interval index. It can also be understood that each measurement interval (or interval pattern) is associated with a measurement interval index. Here, the measurement interval index can be a gap index or a gap pattern identifier (gappattern id), etc.

[0086] In an embodiment of the present application, the measurement interval configuration is configured according to the BWP granularity. In order to configure the measurement interval configuration according to the BWP granularity, each BWP configuration can be associated with a measurement interval index. Specifically, the terminal device receives the second configuration information sent by the network device, the second configuration information includes at least one service cell configuration, each service cell configuration in the at least one service cell configuration includes at least one BWP configuration, and each BWP configuration in the at least one BWP configuration is associated with a measurement interval index. In some optional implementations, the second configuration information is carried in RRC dedicated signaling.

[0087] For example: the network device configures at least one service cell configuration to the terminal device through RRC dedicated signaling. Each service cell configuration includes at least one BWP configuration, and each BWP configuration is associated with a measurement interval index. Here, the measurement interval index can be a gap index or a gap pattern id, etc. For example: the network device configures 4 service cell configurations to the terminal device through RRC dedicated signaling, and each service cell configuration includes 4 BWP configurations. Then, there are a total of 16 BWP configurations, and each of the 16 BWP configurations is associated with a measurement interval index.

[0088] In the above solution, optionally, the BWP may be a dedicated BWP.

[0089] In the above solution, optionally, the BWP may be a downlink BWP or an uplink BWP.

[0090] In the embodiment of the present application, in the case where a service cell is configured with multiple BWPs, only one BWP can be in an activated state, and the terminal device communicates on the activated BWP. Since different BWPs represent different spectrum ranges, the wireless resource usage state of the terminal device is different when the terminal device is in different BWPs. The activated BWP of the service cell can be switched between multiple BWPs. Since the BWP configuration is associated with the measurement interval index, BWP switching (BWP switching) will lead to measurement interval switching (gap switching). It should be noted that BWP switching refers to the switching that occurs when the BWP is activated, and the measurement interval switching refers to the switching that occurs when the gap is activated.

[0091] In the embodiment of the present application, the terminal device determines that a switch from a source BWP to a target BWP is triggered, which can be done in the following ways:

[0092] Mode 1: The terminal device determines that a switch from a source BWP to a target BWP is triggered based on a BWP switch command.

[0093] Specifically, after receiving the BWP switching command, the terminal device switches to the target BWP.

[0094] In some optional implementations, the BWP switching command is carried in the DCI.

[0095] In some optional implementations, the BWP switching command is carried in RRC signaling.

[0096] Mode 2: The terminal device determines, based on the first timer, that a switch from a source BWP to a target BWP is triggered.

[0097] Specifically, after the terminal device enters the source BWP, it starts a first timer, and switches to the target BWP when the first timer times out.

[0098] In the embodiment of the present application, since the source BWP switch is associated with the first measurement interval configuration and the target BWP is associated with the second measurement interval configuration, the terminal device determines that the switch from the source BWP to the target BWP is triggered. It can also be understood that the terminal device determines that the switch from the first measurement interval configuration to the second measurement interval configuration is triggered.

[0099] Step 702: The terminal device determines an activated or enabled measurement interval configuration from the first measurement interval configuration and the second measurement interval configuration, and uses the activated or enabled measurement interval configuration to perform measurement.

[0100] In the embodiment of the present application, after the terminal device determines that a switch from a source BWP to a target BWP is triggered, it is necessary to clarify how to use the pre-configured measurement interval configuration.

[0101] Solution 1

[0102] If the first condition is met, the terminal device immediately activates or enables the second measurement interval configuration after determining that the switching from the source BWP to the target BWP is triggered, and determines that the activated or enabled measurement interval configuration is the second measurement interval configuration.

[0103] In some optional implementations, after determining that a handover from a source BWP to a target BWP is triggered, the terminal device deactivates or abandons the first measurement interval configuration.

[0104] The first condition in the above scheme is explained below. For the convenience of description, the concept of the first moment is introduced. Here, the switching from the source BWP to the target BWP is triggered at the first moment. In addition, it should be noted that in the following description, the duration of the measurement interval may also be referred to as gap duration, and the duration of the measurement interval is determined based on the MGL.

[0105] Solution 1-1): In some optional implementations, the first condition includes: the first moment is not within the duration of the first measurement interval and is within the duration of the second measurement interval.

[0106] Solution 1-2): In some optional implementations, the first condition includes: the first moment is within the duration of the first measurement interval and within the duration of the second measurement interval.

[0107] Solution 1-3): In some optional implementations, the first condition includes: the priority of the second measurement interval configuration is higher than the priority of the first measurement interval configuration.

[0108] Scheme 1-4): In some optional implementations, the first condition includes: the terminal device receives the first indication information sent by the network device, and the first indication information is used to instruct the terminal device to immediately activate or enable the second measurement interval configuration after determining that the switch from the source BWP to the target BWP is triggered.

[0109] It should be noted that the above scheme 1-4) can be implemented in combination with scheme 1-2).

[0110] Solution 2

[0111] If the second condition is met, after determining that the switch from the source BWP to the target BWP is triggered, the terminal device waits for the first time length and then activates or enables the second measurement interval configuration, and determines that the activated or enabled measurement interval configuration is the second measurement interval configuration.

[0112] Here, optionally, the end time of the first duration is the end time of the duration of the first measurement interval. Alternatively, the first duration is determined based on the BWP switching delay, for example, the first duration is equal to the BWP switching delay.
