Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a communication method and apparatus. Background Technology

[0002] The primary purpose of radio resource management (RRM) measurements is to monitor the communication quality of the serving cell and / or neighboring cells of a terminal device in real time, and it is an indispensable part of the communication process between wireless terminal devices and network devices. When a terminal device needs to perform RRM measurements, and the active bandwidth part (BWP) used by the terminal device for data transmission at the current moment does not include the RRM measurement reference signal to be measured (such as the synchronization signal block (SSB) or channel state information reference signal (CSI-RS)), the terminal device needs to complete the RRM measurement through the measurement gap (MGP).

[0003] Currently, network equipment configures the measurement duration and period of MGP for terminal devices. The terminal devices then perform RRM measurements in the serving cell and multiple neighboring cells according to the configured measurement duration and period. Since the location and period of the RRM measurement reference signal may be different in different cells, performing measurements according to the same measurement duration and period is inefficient and results in power waste. Summary of the Invention

[0004] The purpose of this application is to provide a communication method and apparatus to improve the flexibility of RRM measurement.

[0005] Firstly, this application provides a communication method applicable to scenarios where a terminal device performs RRM measurements. The method is executed by a terminal device or a module within a terminal device; here, the terminal device is used as the executing entity for example. The method includes: determining or acquiring first information and second information; the first information may include a first measurement duration and a first measurement cycle, and the second information may include a second measurement duration and a second measurement cycle; and performing RRM measurements using either the first information or the second information.

[0006] In the above method, by configuring multiple measurement durations and measurement cycles for the terminal device, the terminal device can use different measurement durations and measurement cycles to perform measurements under different circumstances, which can improve the flexibility of RRM measurement.

[0007] In one possible implementation, the first measurement duration is less than the second measurement duration; or, the first measurement cycle is greater than the second measurement cycle; or, the first measurement duration is less than the second measurement duration and the first measurement cycle is greater than the second measurement cycle.

[0008] By implementing the above method, when the terminal device uses the first information for RRM measurement, the interruption for activating the BWP is of the first duration, which is shorter than the second duration caused by using the second information for RRM measurement. This significantly reduces the interruption duration of data transmission and improves data transmission efficiency. Furthermore, since the first measurement period is longer than the second measurement period, it also reduces the frequency of data transmission interruptions, further improving data transmission efficiency.

[0009] In one possible implementation, when performing Radio Resource Management (RRM) measurements on a first type of cell, a first measurement period and / or a first measurement duration are applied; when performing RRM measurements on a second type of cell, a second measurement period and a second measurement duration are applied.

[0010] By implementing the above method, and by setting different measurement durations and / or measurement cycles for different types of cells, RRM measurements can be completed using measurement durations and measurement cycles adapted to different scenarios, thereby reducing measurement overhead. Furthermore, when the activated BWP does not include the SSB to be measured, it is also possible to reduce the impact of data transmission interruption on the activated BWP by configuring shorter measurement durations and / or longer measurement cycles.

[0011] In one implementation, the first information and the second information correspond to different types of reference signals. For example, when performing RRM measurements based on a first type of reference signal, a first measurement period and / or a first measurement duration are applied; when performing RRM measurements based on a second type of reference signal, a second measurement period and / or a second measurement duration are applied.

[0012] In one possible implementation, the first type of reference signal is SSB, and the second type of reference signal is CSI-RS.

[0013] In one possible implementation, the period of the first type of reference signal is shorter than the period of the second type of reference signal.

[0014] In one possible implementation, before performing the RRM measurement, the method further includes: determining that activating the BWP does not include the RRM measurement reference signal.

[0015] In one possible implementation, the first type of cell includes serving cells; the second type of cell includes non-serving cells.

[0016] In one possible implementation, the first type of cell includes the serving cell and the non-serving cell whose timing information has a fixed timing difference with the serving cell; the second type of cell includes the non-serving cell whose timing information does not have a fixed timing difference with the serving cell.

[0017] Based on the above method, the timing information of the first type of cell can be obtained in advance without the need for blind detection, which saves the terminal device time in performing RRM measurements compared to the second type of cell. Therefore, when performing RRM measurements on the first type of cell, the first measurement duration can be shorter than the second measurement duration when performing RRM measurements on the second type of cell; and / or, when performing RRM measurements on the first type of cell, the first measurement cycle can be longer than the second measurement cycle when performing RRM measurements on the second type of cell.

[0018] In one possible implementation, before performing RRM measurements on the second type of cell, the method further includes: determining that the measurement results of performing RRM measurements on the first type of cell meet preset conditions.

[0019] In one possible implementation, the preset condition is that the measurement result obtained within at least one first measurement cycle within a preset time range is less than a preset threshold value.

[0020] In one possible implementation, before performing RRM measurements on the second type of cell, the method further includes receiving third information, which instructs the second information to be used to perform RRM measurements on the second type of cell.

[0021] In one possible implementation, the third information is carried via downlink control information (DCI) or media access control (MAC) control element (CE).

[0022] This allows for the rapid initiation of RRM measurements on more non-serving cells using secondary information when the service quality of the serving cell deteriorates, thereby quickly identifying potential alternative cells.

[0023] In one possible implementation, the first measurement duration includes one or more of a first duration, a second duration, or a third duration; during the first duration, the second duration, and the third duration, no physical uplink channels and physical uplink signals are transmitted to the network device, and no physical downlink channels and downlink signals are received from the network device; wherein, the first duration is the continuous transmission duration of the RRM measurement reference signal to be measured; the second duration is a preset duration before the start symbol of the RRM measurement reference signal; and the third duration is a preset duration after the end symbol of the RRM measurement reference signal.

[0024] This reduces the impact of terminal device behavior on RRM measurement, improves the accuracy of RRM measurement, and increases resource utilization.

[0025] In one possible implementation, the second duration is 140 μs or 500 μs; the third duration is 140 μs or 500 μs.

[0026] In one possible implementation, during the first measurement period, no physical uplink channel and physical uplink signal are sent to the network device, and no physical downlink channel and downlink signal are received from the network device.

[0027] This can reduce the impact of terminal device behavior on RRM measurement and improve the accuracy of RRM measurement.

[0028] In one possible implementation, the first measurement duration is the same as the measurement duration of the Synchronous Information Block Measurement Timing Configuration (SMTC), and / or the first measurement cycle is the same as the measurement cycle of the SMTC.

[0029] Based on this implementation, the SMTC configuration can be reused, thereby saving the signaling overhead of configuring the first measurement duration and / or the first measurement cycle.

[0030] In one possible implementation, the first measurement duration is less than or equal to 1 millisecond, and the first measurement period is greater than or equal to 40 milliseconds.

[0031] This ensures that the first measurement duration is shorter than the second measurement duration, and the first measurement cycle is longer than the second measurement cycle.

[0032] In one possible implementation, the first measurement duration and the first measurement period satisfy any one of the following: the first measurement duration is equal to 1.5 milliseconds and the first measurement period is equal to 20 milliseconds; the first measurement duration is equal to 1.5 milliseconds and the first measurement period is equal to 40 milliseconds; the first measurement duration is equal to 1.5 milliseconds and the first measurement period is equal to 80 milliseconds; or the first measurement duration is equal to 1.5 milliseconds and the first measurement period is equal to 160 milliseconds.

[0033] This ensures that the first measurement interval has the shortest possible duration and also allows for the reuse of existing interval patterns, improving system compatibility.

[0034] In one possible implementation, the frequency range corresponding to the first information is the same as the frequency range corresponding to the second information.

[0035] Secondly, this application provides a communication method applicable to scenarios where a terminal device performs RRM measurements. The method is executed by a network device or a module within a network device; here, a terminal device is used as the executing entity for example. The method includes: determining first information and second information; the first information includes a first measurement duration and a first measurement cycle, and the second information includes a second measurement duration and a second measurement cycle; and indicating the first and second information to the terminal device.

[0036] In one possible implementation, the first measurement duration is shorter than the second measurement duration, and / or the first measurement cycle is longer than the second measurement cycle.

[0037] In one implementation, a first measurement period and / or a first measurement duration are applied to perform RRM measurements on a first type of cell; a second measurement period and a second measurement duration are applied to perform RRM measurements on a second type of cell.

[0038] In one implementation, the first information and the second information correspond to different types of reference signals. For example, when performing RRM measurements based on a first type of reference signal, a first measurement period and / or a first measurement duration are applied; when performing RRM measurements based on a second type of reference signal, a second measurement period and / or a second measurement duration are applied.

[0039] In one possible implementation, the first type of reference signal is SSB, and the second type of reference signal is CSI-RS.

[0040] In one possible implementation, the period of the first type of reference signal is shorter than the period of the second type of reference signal.

[0041] In one possible implementation, the first type of cell includes serving cells; the second type of cell includes non-serving cells.

[0042] In one possible implementation, the first type of cell includes the serving cell and the non-serving cell whose timing information has a fixed timing difference with the serving cell; the second type of cell includes the non-serving cell whose timing information does not have a fixed timing difference with the serving cell.

[0043] In one possible implementation, the method further includes sending third information to the terminal device, the third information being used to instruct the second information to perform RRM measurement on the second type of cell.

[0044] In one possible implementation, the third information is carried via downlink control information (DCI) or media access control (MAC) control element (CE).

[0045] In one possible implementation, the first measurement duration includes one or more of a first duration, a second duration, or a third duration; during the first duration, the second duration, and the third duration, no physical uplink channels and physical uplink signals are received from the terminal device, and no physical downlink channels and downlink signals are sent to the terminal network device.

[0046] The first duration is the continuous transmission duration of the RRM measurement reference signal to be measured; the second duration is the preset duration before the start symbol of the RRM measurement reference signal; and the third duration is the preset duration after the end symbol of the RRM measurement reference signal.

[0047] In one possible implementation, the second duration is 140 μs or 500 μs; the third duration is 140 μs or 500 μs.

[0048] In one possible implementation, during the first measurement period, no physical uplink channel and physical uplink signal are received from the terminal device, and no physical downlink channel and downlink signal are sent to the terminal network device.

[0049] In one possible implementation, the first measurement duration is the same as the measurement duration of the Synchronous Information Block Measurement Timing Configuration (SMTC), and / or the first measurement cycle is the same as the measurement cycle of the SMTC.

[0050] In one possible implementation, the first measurement duration is less than or equal to 1 millisecond, and the first measurement period is greater than or equal to 40 milliseconds.

[0051] In one possible implementation, the first measurement duration and the first measurement period satisfy any one of the following: the first measurement duration is equal to 1.5 milliseconds and the first measurement period is equal to 20 milliseconds; the first measurement duration is equal to 1.5 milliseconds and the first measurement period is equal to 40 milliseconds; the first measurement duration is equal to 1.5 milliseconds and the first measurement period is equal to 80 milliseconds; or the first measurement duration is equal to 1.5 milliseconds and the first measurement period is equal to 160 milliseconds.

[0052] In one possible implementation, the frequency range corresponding to the first information is the same as the frequency range corresponding to the second information.

[0077] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0078] The technical solutions of this application can be applied to various communication systems, such as the Long Term Evolution (LTE) system, NR system, and next-generation communication system developed by the 3rd Generation Partnership Project (3GPP), and are not limited herein.

[0079] In this application embodiment, the terminal device can be a device with wireless transceiver capabilities or a chip that can be installed in any device. It can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user device. The terminal device in this application embodiment can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving vehicles, etc. The network device can be a next-generation node B (gNB) in an NR system, or an evolved Node B (eNB) in an LTE system, etc.

[0080] The terminal device in this application can be a first type of terminal device or a second type of terminal device. The first type of terminal device and the second type of terminal device can have at least one of the following distinguishing features:

[0081] 1. Different bandwidth capabilities. Bandwidth capability can be expressed as the maximum baseband bandwidth processing capacity. For example, the first type of terminal device supports a bandwidth of no more than 40MHz, while the second type of terminal device supports a bandwidth greater than 40MHz. For instance, in NR version 15 (release-15, Rel-15) or NR version 16 (release-16, Rel-16), the second type of terminal device supports a bandwidth capability of 100MHz, while the first type of terminal device supports a bandwidth capability of only 20MHz within frequency range 1 (FR1).

[0082] 2. The number of transmitting and receiving antennas differs. For example, the first type of terminal device can support 2 receive and 1 transmit (2 receiving antennas and 1 transmitting antenna), or 1 receive and 1 transmit (1 receiving antenna and 1 transmitting antenna). The second type of terminal device can support 4 receive and 2 transmit (4 receiving antennas and 2 transmitting antennas).

[0083] 3. The maximum uplink transmit power differs. For example, the maximum uplink transmit power of Type I terminal equipment can be a value between 4 dBm and 20 dBm. The maximum uplink transmit power of Type II terminal equipment can be 23 dBm or 26 dBm.

[0084] 4. Different protocol versions. The first type of terminal device can be a terminal device in NR version 17 (release-17, Rel-17) or NR Rel-17 or later. The second type of terminal device can be a terminal device in NR version 15 (release-15, Rel-15) or NR version 16 (release-16, Rel-16).

[0085] 5. Different carrier aggregation capabilities. For example, type 1 terminal devices do not support carrier aggregation, while type 2 terminal devices do. Alternatively, both type 1 and type 2 terminal devices can support carrier aggregation, but the maximum number of carrier aggregations that type 1 terminal devices can support simultaneously is less than the maximum number of carrier aggregations that type 2 terminal devices can support simultaneously.

[0086] 6. Different duplex capabilities. For example, the first type of terminal equipment supports half-duplex frequency division duplexing (FDD). The second type of terminal equipment supports full-duplex FDD.

[0087] 7. Different data processing time capabilities. For example, the minimum latency between receiving downlink data and sending feedback on that downlink data for a Type 1 terminal device is greater than that between receiving downlink data and sending feedback on that downlink data for a Type 2 terminal device; and / or, the minimum latency between sending uplink data and receiving feedback on that uplink data for a Type 1 terminal device is greater than that between sending uplink data and receiving feedback on that uplink data for a Type 2 terminal device.

[0088] 8. Differences in processing capability. For example, the baseband processing capability of the first type of terminal device is lower than that of the second type of terminal device. Baseband processing capability may include at least one of the following: the maximum number of multiple input multiple output (MIMO) layers supported by the terminal device during data transmission, the number of hybrid automatic repeat request (HARQ) processes supported by the terminal device, and the maximum transmission block size (TBS) supported by the terminal device.

[0089] 9. The uplink and / or downlink peak transmission rates are different. The peak transmission rate refers to the maximum data transmission rate that the terminal device can achieve per unit time (e.g., per second). The uplink peak rate supported by the first type of terminal device may be lower than the uplink peak rate supported by the second type of terminal device, and / or the downlink peak rate supported by the first type of terminal device may be lower than the downlink peak rate supported by the second type of terminal device.

[0090] 10. Different buffer sizes. A buffer can be understood as the total size of the Layer 2 (L2) buffer, or it can be understood as the total number of soft channel bits that HARQ processing can use.

[0091] Optionally, the first type of terminal equipment may refer to a REDCAP terminal equipment, or it may also refer to a low-capability terminal equipment, a reduced-capability terminal equipment, a REDCAP UE, a Reduced Capacity UE, a narrow-band NR (NB-NR) UE, etc. The second type of terminal equipment may refer to a terminal equipment with traditional capability, normal capability, or high capability, and may also be called a legacy terminal equipment or a normal terminal equipment. The second type of terminal equipment has, but is not limited to, the distinguishing features between it and the first type of terminal equipment.

[0092] Figure 1 This is a schematic diagram of a network architecture applicable to this application. For example... Figure 1 As shown, a terminal device can connect to a network device to obtain services from an external network (such as a data network (DN)) or to communicate with other devices, such as other terminal devices.

[0093] by Figure 1 Taking NR systems as an example, network devices can configure multiple bandwidth parts (BWPs) for terminal devices. A BWP can consist of a set of consecutive common resource blocks (CRBs) with a specific carrier and a specific set of parameters. The operating bandwidth of the terminal device can change dynamically, for example... Figure 2 As shown, the terminal device has a large traffic volume, and the network equipment can configure a high-bandwidth BWP for this terminal device. Figure 2 In this context, it's represented by BWP1, for example, with a bandwidth of 40MHz; when the terminal device's traffic is low, the network device can configure a small-bandwidth BWP for that terminal device. Figure 2In this context, it is represented by BWP2, for example, with a bandwidth of 20MHz. This allows resources to be allocated to terminal devices according to actual conditions, thereby improving resource utilization.

[0094] In an NR system, although multiple Backplane View Devices (BWPs) are configured for a terminal device, only one BWP can be active at any given time. The terminal device uses this active BWP to transmit data with the network device. This data transmission includes, but is not limited to, receiving downlink data from the network device and sending uplink data to the network device. Downlink data includes data carried through downlink physical channels, such as data carried through the Physical Downlink Control Channel (PDCCH) and the Physical Downlink Shared Channel (PDSCH), as well as downlink signals. Uplink data includes data carried through physical uplink channels, such as data carried through the Physical Uplink Control Channel (PUCCH) and the Physical Uplink Shared Channel (PUSCH), as well as uplink signals.

[0095] To monitor the communication quality of the serving cell and / or neighboring cells of a terminal device in real time, the network device can instruct the terminal device to perform RRM measurements according to the measurement configuration and report the RRM measurement results. Taking the RRM measurement reference signal as SSB as an example, such as... Figure 3 As shown, Figure 3 In this diagram, BWP 1 is the active BWP and does not include the SSB; BWP 2 includes the SSB. When a terminal device needs to perform RRM measurements, if the active BWP does not include the SSB to be measured, the terminal device needs to interrupt data transmission on the active BWP and switch to BWP 2 to perform RRM measurements via MGP. Performing RRM via MGP can be understood as performing RRM measurements according to the MGP configuration information. Specifically, within the MGP, the terminal device may perform RRM measurements. Performing RRM via MGP can also be understood as, within the MGP, the terminal device does not (expect) send physical uplink channels and physical uplink signals to the network device, and does not (expect) receive physical downlink channels and downlink signals from the network device, and within the MGP, the terminal device may still perform RRM measurements.

[0096] It should be noted that if the activated BWP includes the RRM measurement signal to be measured, such as SSB, the terminal device does not need to interrupt the data transmission on the activated BWP. RRM measurement and data transmission can be performed simultaneously within the activated BWP.

[0097] Since RRM measurement is an indispensable measurement for terminal devices, ensuring service continuity, it needs to be performed frequently on the terminal device side. When the active BWP does not include the RRM measurement reference signal to be measured, the terminal device needs to switch to another BWP for RRM measurement, causing frequent data transmission interruptions on the active BWP. Current estimates suggest that due to these frequent interruptions, approximately 15% of the resources on the active BWP are unavailable for data transmission, thus reducing data transmission continuity and resource utilization. This application provides a method to reduce the resource overhead caused by RRM measurement, ensure data transmission continuity for low-capacity terminal devices, and improve the flexibility of RRM measurement, which will be described in detail below.

[0098] The network architecture and business scenarios described in this application are intended to more clearly illustrate the technical solutions of this application and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0099] In this application, the interaction between a network device and a terminal device is used as an example for explanation. The operation performed by the network device can also be performed by a chip or module inside the network device, and the operation performed by the terminal device can also be performed by a chip or module inside the terminal device.

[0100] Based on the preceding description, such as Figure 4 The diagram shown is a schematic flowchart of a communication method provided in an embodiment of this application. This method can be applied to various scenarios, including but not limited to scenarios where RRM measurement is performed via MGP when the BWP is activated but the RRM measurement reference signal is not included. See [link to relevant documentation]. Figure 4 The method includes:

[0101] Optionally, S401: The network device determines the first information and the second information.

[0102] The first information includes a first measurement duration and a first measurement cycle, and the second information includes a second measurement duration and a second measurement cycle. The first information and the second information can satisfy any of the following relationships:

[0103] The first measurement duration is shorter than the second measurement duration;

[0104] The first measurement cycle is longer than the second measurement cycle;

[0105] The first measurement duration is shorter than the second measurement duration, and the first measurement cycle is longer than the second measurement cycle.

[0106] Optionally, the first measurement duration and the first measurement cycle are configuration parameters of the first measurement interval, and the second measurement duration and the second measurement cycle are configuration parameters of the second measurement interval.

[0107] It should be noted that within the measurement interval, the terminal device is allowed to adjust the radio frequency from the active BWP (Band WP) excluding the RRM measurement reference signal to a BWP that includes the RRM measurement reference signal to be measured, or to a frequency range that includes the RRM measurement reference signal to be measured, through radio frequency tuning (RF tuning), to complete the RRM measurement. For example... Figure 5 As shown, the measurement interval includes parameters such as measurement duration and measurement cycle.

[0108] The BWP or frequency range of the RRM measurement reference signal to be measured can be configured by the network device to the terminal device. For example, the network device can be configured through the measurement objective (MO) to indicate the BWP or frequency range of the RRM measurement reference signal to be measured; or, for example, the network device can configure the frequency information of the RRM measurement reference signal to be measured through the MO, such as through the absolute radio frequency channel number (ARFCN). The RRM measurement reference signal can include, but is not limited to, SSB and CSI-RS.

[0109] Furthermore, if the configuration of measurement intervals at the frequency range (FR) granularity is supported, in this embodiment, the frequency range corresponding to the first information and the frequency range corresponding to the second information are the same. That is, the terminal device can configure different measurement intervals within the same FR. For example, the first information and the second information may both correspond to FR1 (frequency range below 6 GHz), or both correspond to FR2 (frequency range above 6 GHz), or both correspond to another frequency range. For instance, if the terminal device supports the frequency range FR1, then the first information and the second information determined by the terminal device are used for RRM measurements in cells within FR1; if the terminal device supports the frequency range FR2, then the first information and the second information determined by the terminal device are used for RRM measurements in cells within FR2. If the terminal device supports both FR1 and FR2, the network device can configure the first information and the second information for RRM measurements in cells within FR1, and the first information and the second information for RRM measurements in cells within FR2, respectively. Specifically, the first information corresponding to FR1 and the first information corresponding to FR2 can be the same, and the second information corresponding to FR1 and the second information corresponding to FR2 can be the same.

[0110] Furthermore, the first information may also include a first time offset of the first measurement interval. The first time offset can be the time offset of the time domain position of the first measurement interval relative to a reference timing. For example, the reference timing can be the timing information of the serving cell serving the terminal device, such as the system frame number (SFN) of the serving cell. The terminal device can determine the radio frame and time slot where the first measurement interval is located based on the first time offset of the first measurement interval, the first measurement duration, and the first measurement period. Correspondingly, the second information may also include a second time offset of the second measurement interval.

[0111] In this application, the specific method by which the network device determines the second information is not limited. The following examples illustrate how the network device determines the first information, including the first measurement duration and the first measurement period.

[0112] In the first possible implementation, the first measurement duration belongs to a first set of durations, which includes at least one measurement duration. The network device can select one measurement duration from the first set of durations as the first measurement duration based on actual conditions. The first measurement period belongs to a first set of periods, which includes multiple measurement periods. The network device can select one measurement period from the first set of periods as the first measurement period based on actual conditions. Similarly, the second measurement duration can correspond to a second set of durations, and the second measurement period can correspond to a second set of periods.

[0113] The first and second duration sets may or may not intersect; similarly, the first and second period sets may or may not intersect. For example, the first duration set might be {0.5ms, 1ms, 1.5ms}, and the second duration set might be {1.5ms, 3ms, 4ms, 6ms}. The first period set might be {10ms, 20ms, 40ms}, and the second period set might be {20ms, 40ms, 60ms, 80ms}. The first and second duration sets can be identical, meaning they include the same measurement duration; similarly, the first and second period sets can be identical, meaning they include the same measurement period. For example, the first duration set and the second duration set are both {0.5ms, 1ms, 2ms, 3ms, 3.5ms, 4ms, 5.5ms, 6ms} or subsets of such sets, and the first period set and the second period set are both {20ms, 40ms, 80ms, 160ms, 320ms, 640ms} or subsets of such sets.

[0114] Optionally, when the second measurement duration and the second measurement period are configuration parameters of the second measurement interval, since the minimum measurement duration of the current measurement interval is 1.5ms and the minimum measurement period is 20ms, in order to ensure that the first measurement duration is less than the second measurement duration and the first measurement period is greater than the second measurement period, in this embodiment of the application, the first measurement duration can be less than or equal to 1ms and the first measurement period can be greater than or equal to 40ms.

[0115] In the second possible implementation, the first measurement duration or first measurement period included in the first information can reuse the measurement duration and measurement period of other measurement intervals. For example, multiple interval patterns can be predefined, each interval pattern corresponding to an identifier, measurement duration, and measurement period. When configuring the first information, directly indicating the identifier of an interval pattern means configuring the first measurement duration and first measurement period of the first information to the measurement duration and measurement period corresponding to that identifier.

[0116] For example, as shown in Table 1, there are predefined interval patterns. In Table 1, the first column represents the identifier of the interval pattern, the second column represents the measurement duration corresponding to the identifier, and the third column represents the measurement cycle corresponding to the identifier.

[0117] Table 1

[0118] logo Measurement duration (ms) Measurement period (ms) 0 6 40 1 6 80 2 3 40 3 3 80 4 6 20 5 6 160 6 4 20 7 4 40 8 4 80 9 4 160 10 3 20 11 3 160 12 5.5 20 13 5.5 40 14 5.5 80 15 5.5 160 16 3.5 20 17 3.5 40 18 3.5 80 19 3.5 160 20 1.5 20 21 1.5 40 22 1.5 80 23 1.5 160 24 10 80 25 20 160

[0119] In this embodiment of the application, in order to make the first measurement duration less than the second measurement duration, one or more interval patterns with the smallest measurement duration in Table 1 can be used as candidate configurations for the first measurement interval.

[0120] For example, taking the interval patterns marked 20 to 23 in Table 1 as an example, on the one hand, the measurement duration corresponding to patterns marked 20 to 23 is the shortest; on the other hand, the interval patterns marked 20 to 23 are only applied to FR2. Therefore, one or more interval patterns marked 20 to 23 in Table 1 can be used as candidate configurations for the first measurement interval. Moreover, the first measurement interval can correspond to FR1 or FR2, which ensures that the first measurement interval has the shortest duration and also allows for the reuse of existing interval patterns. In this case, the first measurement duration and the first measurement cycle can satisfy any of the following:

[0121] The first measurement duration is 1.5 milliseconds, and the first measurement period is 20 milliseconds;

[0122] The first measurement duration is 1.5 milliseconds, and the first measurement period is 40 milliseconds;

[0123] The first measurement duration is 1.5 milliseconds, and the first measurement period is 80 milliseconds;

[0124] The first measurement duration is 1.5 milliseconds, and the first measurement period is 160 milliseconds.

[0125] Optionally, new interval patterns can be added to the existing table, serving as candidate configurations for the first measurement interval. For example, the measurement duration corresponding to the new interval pattern can be less than or equal to 1 millisecond, and the measurement period can be greater than or equal to 40 milliseconds. The identifier corresponding to the new interval pattern is greater than 25.

[0126] Optionally, the interval pattern used by the terminal device can be all the interval patterns included in Table 1, or a subset of all the interval patterns included in Table 1, or a combination of all or some of the interval patterns included in Table 1 and newly added interval patterns.

[0127] In the third possible implementation, the first measurement duration and the first measurement cycle can be determined based on the Synchronous Information Block Measurement Timing Configuration (SMTC).

[0128] For example, the terminal device can determine the first measurement duration and the first measurement period based on the SMTC corresponding to the frequency information of the RRM measurement reference signal for the serving cell. Specifically, the frequency information of the RRM measurement reference signal can be determined through the ARFCN, and the SMTC corresponding to the ARFCN is used to determine the first measurement duration and the first measurement period. The measurement period of the SMTC is equal to the first measurement period, and the measurement duration (window length) of the SMTC is equal to the first measurement duration. It should be noted that the SMTC is used to search for SSBs. In most cases, SSBs are not continuous in the time domain. When performing measurements, the terminal device does not need to continuously search and measure in the time domain, but only needs to be able to lock the time window where the SSB is located. Therefore, the concept of SMTC is introduced in the measurement configuration. The SMTC appears in the time domain at a certain period, and its duration is a fixed measurement window. The measurement period ranges from 5 to 160 ms, and the window length ranges from 1 to 5 ms. From the measurement perspective, the terminal device will assume that there are no SSBs outside the window. The network device can configure the measurement period and window length of the SMTC through the measurement object (MO). Generally, SMTC configuration is per frequency point, meaning each frequency point corresponds to one SMTC configuration. Based on this, the terminal device can use the SMTC configuration corresponding to a specific frequency point (e.g., the SMTC configuration corresponding to the frequency information of the RRM measurement reference signal for the serving cell) as the configuration for the first measurement interval. Alternatively, it can be understood that, based on this, the terminal device can determine the first measurement duration and the first measurement period. This implementation method can save the signaling overhead of network devices configuring the first measurement interval.

[0129] S402: The network device indicates the first information and the second information to the terminal device.

[0130] The first and second information can be carried by radio resource control (RRC) signaling, and they can reside in the same RRC signaling message. For example, a network device can send RRC signaling message containing the first and second information to a terminal device. The RRC signaling message can be, for example, an information element (IE) named MeasGapConfig.

[0131] It should be noted that, in addition to being configurable via RRC signaling, the first and second information can also be configured via other types of signaling such as DCI, which will not be listed here.

[0132] In one possible implementation, the network device can directly indicate the second measurement duration and the second measurement period included in the second information. For example, the network device can send the second information. Specifically, the second information sent by the network device can be as follows:

[0133]

[0134] Wherein, gapoffset represents the second time offset, which can be the time offset of the time domain position of the second measurement interval relative to the reference timing. For example, the reference timing can be the timing information of the serving cell serving the terminal device, or the timing information of the non-serving cell of the terminal device. The non-serving cell of the terminal device can be the non-serving cell determined by the terminal device through SSB detection, or the non-serving cell configured by the network device, such as a neighboring cell; mgl represents the second measurement duration, indicating the measurement interval length of the second measurement interval, in milliseconds (ms); mgrp represents the second measurement period, used to indicate the measurement interval repetition period of the second measurement interval, in milliseconds.

[0135] In addition to the information mentioned above, GapConfig can also include other information without specific limitations.

[0136] The network device can directly indicate the first measurement duration and the first measurement period, which are included in the first information, or it can indirectly indicate either the first measurement duration or the first measurement period. For the network device to directly indicate the first measurement duration and the first measurement period, refer to the description of the second information. When the network device indirectly indicates the first measurement duration, it can configure the first measurement duration and the second measurement duration to have the same value, but the network device only indicates the second measurement duration; that is, the first measurement duration can reuse the second measurement duration. Similarly, when the network device indirectly indicates the first measurement period, it can configure the first measurement period and the second measurement period to have the same value, but the network device only indicates the second measurement period.

[0137] For example, combining the second piece of information from the example above, when the network device directly indicates the first measurement duration, the first and second pieces of information sent by the network device can be as follows:

[0138]

[0139] In this context, assuming that GapConfig1 corresponds to the first information, then gapoffset included in GapConfig1 represents the first time offset, mgl represents the first measurement duration, and mgrp represents the first measurement period.

[0140] For example, combining the second piece of information from the example above, when the network device indirectly indicates the first measurement duration, the first piece of information sent by the network device can be as follows:

[0141]

[0142]

[0143] That is, it is still assumed that GapConfig1 corresponds to the first information, or that GapConfig1 does not include the IE mg1, or that it includes mg1 but configures an invalid value for mgl.

[0144] In the example above, the first information does not include the first measurement duration. The terminal device can determine the first measurement cycle based on the first information, and then determine the first measurement duration based on the second information.

[0145] To give another example, combining the second piece of information from the example above, when the network device indirectly indicates the first measurement period, the first piece of information sent by the network device can be as follows:

[0146]

[0147] That is, it is still assumed that GapConfig1 corresponds to the first information, or that GapConfig1 does not include the mgrp IE, or it includes mgrp but configures invalid values ​​for mgrp.

[0148] In the example above, the first information does not include the first measurement cycle. The terminal device can determine the first measurement duration based on the first information, and then determine the first measurement cycle based on the second information.

[0149] In another possible implementation, when the first measurement duration is equal to the measurement duration of the SMTC, and / or the first measurement cycle is equal to the measurement cycle of the SMTC, the network device may not send the first information, but instead instruct the terminal device to determine the first information according to the SMTC.

[0150] The above are just examples. Network devices can also indicate the first and second information in other ways, which will not be listed here.

[0151] Optionally, S403: The terminal device determines the first information and the second information.

[0152] The specific methods by which the terminal device determines the second information will not be elaborated here; please refer to existing technologies for details.

[0153] There may be several ways for the terminal device to determine the first information. One approach is that when the network device directly indicates the first information, it can send the first information via RRC signaling or similar methods. In this case, the terminal device can receive the first information from the network device, thereby obtaining the first measurement duration and the first measurement period included in the first information.

[0154] In the second implementation method, when the network device directly indicates the first information, the first information includes the first measurement duration or the first measurement period. The terminal device can determine the first measurement duration based on the received first information, and then determine the first measurement period based on the second information; or, the terminal device can determine the first measurement period based on the received first information, and then determine the first measurement duration based on the second information.

[0155] For example, the first information received by the terminal device includes the first measurement duration but does not include the first measurement cycle; the terminal device may assume that the first measurement cycle is equal to the second measurement cycle in the second information, and thus determine the first measurement cycle based on the second measurement cycle.

[0156] In the third implementation method, when the network device instructs the terminal device to determine the first information based on the SMTC, the terminal device can use the measurement duration (window length) and measurement period of the SMTC corresponding to a specific frequency point, such as the window length and period of the SMTC corresponding to the frequency information of the RRM measurement reference signal corresponding to the serving cell, as the first measurement duration and the first measurement period. The specific frequency point can be a frequency point configured by the network device, a default frequency point, or a frequency point determined autonomously by the terminal device; this embodiment does not limit the specific frequency point.

[0157] S404: The terminal device uses either the first information or the second information to perform RRM measurement.

[0158] Optionally, when the above method is applied to a scenario where RRM measurement is performed via MGP, before the terminal device performs RRM measurement, it can be determined that activating BWP does not include the RRM measurement reference signal. When activating BWP without the RRM measurement reference signal, RRM measurement can be performed using either the first information or the second information. Here, "excluding the RRM measurement reference signal" means excluding the RRM measurement reference signal configured for the terminal device.

[0159] In the above method, by configuring multiple measurement durations and measurement cycles for the terminal device, the terminal device can use different measurement durations and measurement cycles to perform measurements under different circumstances, which can improve the flexibility of RRM measurement.

[0160] In this application embodiment, the specific use of the first information or the second information by the terminal device for RRM measurement is not limited. For example, when performing RRM measurement on a first type of cell, the terminal device uses a first measurement period and / or a first measurement duration; when performing the RRM measurement on a second type of cell, the terminal device uses a second measurement period and a second measurement duration.

[0161] In one possible implementation, the terminal device performs RRM measurements on the serving cell using first information and on the non-serving cell using second information. Specifically, the first type of cell includes the serving cell of the serving terminal device, and the second type of cell includes non-serving cells. Non-serving cells refer to cells other than the serving cell, including but not limited to neighboring cells of the serving cell.

[0162] In another possible implementation, besides using the first information to perform RRM measurements on the serving cell, the first information can also be used to perform RRM measurements on cells in a first set of non-serving cells. This first set of non-serving cells includes at least one non-serving cell. The timing information of all non-serving cells in this first set has a fixed timing difference from the timing information of the serving cell. That is, for a non-serving cell in the first set of non-serving cells, the terminal device can determine the timing information of the non-serving cell based on the timing information of the serving cell, without needing to detect the time position information of the RRM measurement reference signal in the non-serving cell through blind detection. It should be noted that the fixed timing difference with the timing information of the serving cell can be understood as the terminal device being able to determine the timing information of the non-serving cell using the timing information of the serving cell. For example, the terminal device can assume that the SFN of the serving cell is the same as the SFN of the non-serving cell with the fixed timing difference, or the terminal device can assume that the SSB index information of the non-serving cell with the fixed timing difference can be derived from the timing information of the serving cell.

[0163] In addition, the terminal device uses the second information to perform RRM measurements on cells in the second set of non-serving cells. The second set of non-serving cells includes at least one non-serving cell. There is no fixed timing difference between the timing information of all non-serving cells in this set and the timing information of the serving cell. That is, the terminal device is unaware of the timing information of any non-serving cell in the second set of non-serving cells. The terminal device needs to determine the timing information of the non-serving cell by detecting the time position information of the RRM measurement reference signal in that non-serving cell through blind detection.

[0164] Based on the above description, in this implementation, the first type of cell includes the serving cell and the non-serving cell with a fixed timing difference from the timing information of the serving cell, or in other words, the first type of cell includes the serving cell and the non-serving cell that can determine the timing information of its own cell based on the timing information of the serving cell; the second type of cell includes the non-serving cell that does not have a fixed timing difference from the timing information of the serving cell, or in other words, the second type of cell includes the non-serving cell that cannot determine the timing information of its own cell based on the timing information of the serving cell.

[0165] In the above method, since the timing information of the first type of cell can be obtained in advance, it does not need to be obtained through blind detection. Compared with the second type of cell, this saves the time for the terminal device to perform RRM measurement. Therefore, when performing RRM measurement on the first type of cell, the first measurement duration of the RRM measurement can be shorter than the second measurement duration when performing RRM measurement on the second type of cell; and / or, when performing RRM measurement on the first type of cell, the first measurement cycle of the RRM measurement can be longer than the second measurement cycle when performing RRM measurement on the second type of cell.

[0166] Based on this, in the embodiments of this application, by setting different measurement durations and / or measurement cycles for different types of cells, RRM measurements can be completed using measurement durations and measurement cycles adapted to different scenarios, thereby reducing measurement overhead. Furthermore, when the activated BWP does not include the SSB to be measured, the impact of interruptions on data transmission on the activated BWP may also be reduced by configuring shorter measurement durations and / or longer measurement cycles.

[0167] It should be noted that the terminal device can perform RRM measurements on the first type of cell using the first information and on the second type of cell using the second information without additional signaling notification. That is, if the terminal device determines that the first measurement duration is less than the second measurement duration, and / or that the first measurement period is greater than the second measurement period, it can default to performing RRM measurements on the first type of cell within the first measurement duration according to the first measurement period, and performing RRM measurements on the second type of cell within the second measurement duration according to the second measurement period. Where the first type of cell includes non-serving cells, the cell identifiers of the non-serving cells included in the first type of cell can be notified to the terminal device by the network device. For example, the network device can indicate the cell identifiers of the non-serving cells included in the first type of cell to the terminal device via RRC signaling.

[0168] Optionally, the terminal device may prioritize using the first information to perform RRM measurements on the first type of cell. When the terminal device determines that the measurement result of the RRM measurement on the first type of cell meets a preset condition, it then uses the second information to perform RRM measurements on the second type of cell. The preset condition may be that the measurement result obtained within at least one first measurement period within a preset time range is less than a preset threshold. In this case, if the measurement result is from an RRM measurement performed on a serving cell, it can be understood that the service quality of the terminal device in the current serving cell has deteriorated. If the measurement result also includes the measurement result of an RRM measurement performed on a non-serving cell within the first type of cell, it can also be understood that non-serving cells with known timing information are not suitable as alternative serving cells. In this case, the terminal device needs to use the second information to perform RRM measurements on the second type of cell. By detecting the measurement result of the RRM measurement on the second type of cell, it can determine whether there are cells that may serve as alternative serving cells for the terminal device, thus ensuring data transmission continuity.

[0169] It should be noted that, in the embodiments of this application, the measurement results of RRM measurement include one or more of the following: reference signal received power (RSRP) measurement results, reference signal received quality (RSRQ) measurement results, or signal interference noise ratio (SINR) measurement results. The RRM measurement results can be implemented based on SSB or other reference signals such as CSI-RS. When implemented based on SSB, the RRM measurement can be performed based on one or more of the following included in the SSB: primary synchronization signal (PSS), secondary synchronization signal (SSS), or demodulation reference signal (DMRS) used for demodulating the physical broadcast channel (PBCH).

[0170] Optionally, in this embodiment of the application, the terminal device may also report the measurement results of performing RRM measurement on the first type of cell using the first information through non-periodic or periodic measurement reporting, or the terminal device may also directly send trigger request information to the network device, the trigger request information being used to request the use of the second information to perform RRM measurement.

[0171] The network device can send third information to the terminal device, which is used to instruct the second information to be used to perform RRM measurement; further, the third information can instruct the second information to be used to perform RRM measurement on the second type of cell.

[0172] The third information may be sent by the network device when it determines that the measurement result reported by the terminal device through non-periodic or periodic measurement is less than a preset threshold; the third information may also be sent by the network device after receiving a trigger request information from the terminal device; the third information may also be sent under other circumstances, which are not limited in the embodiments of this application.

[0173] The third information can be carried through physical layer signaling, downlink control information (DCI), or medium access control (MAC) control elements (CE). It's important to note that this third information is not carried via RRC reconfiguration messages, but rather through physical layer signaling, DCI, or MAC CE, which is faster than RRC reconfiguration message delivery. This reduces the impact of measurement intervals on BWP data transmission activation and allows for rapid initiation of RRM measurements on more non-serving cells using the second information when the service quality of the serving cell deteriorates, thus quickly identifying potential alternative cells. Optionally, when configuring the first and second information, the timing of the second measurement duration and the second measurement period included in the second information can be indicated by the network device via MAC CE or DCI.

[0174] Optionally, third information can also be indicated via RRC signaling.

[0175] On the other hand, the terminal device can prioritize using the first information to perform RRM measurements on the first type of cell. When the terminal device determines that the measurement result of the RRM measurement on the first type of cell meets the preset conditions, it uses the second information to perform RRM measurements on the second type of cell. It then notifies the network device of the use of the second information for RRM measurement via the uplink data transmission channel with the base station, so that the network device avoids data transmission with the terminal device during the second measurement duration and second measurement period corresponding to the second information. The uplink data transmission channel can be either PUCCH or PUSCH, without specific limitations.

[0176] It should be noted that, in addition to using the second information to perform RRM measurements on the second type of cell, the terminal device can also use the second information to perform RRM measurements on the first type of cell. Thus, when the terminal device determines that the measurement results obtained by performing RRM measurements within the serving cell are better than those obtained by performing RRM measurements within a non-serving cell, it can reuse the first information to perform RRM measurements on the first type of cell.

[0177] The following is a specific application scenario illustrating under what circumstances a terminal device might first use the first information to perform RRM measurement, and then use the second information to perform RRM measurement. For example, such as... Figure 6 As shown, in this example, the network device is configured with first information and second information. The first information may be a first measurement interval (e.g., Figure 6 The measurement duration and measurement cycle configured in GAP1, and the second information can be for the second measurement interval (e.g., Figure 6 The measurement duration and measurement cycle are configured in GAP2. Figure 6 During the process, the terminal device moves from the center of the serving cell to the edge of the serving cell. During this movement, the terminal device performs RRM measurements using different measurement durations and / or measurement cycles. Specifically, when at the center of the serving cell, the terminal device can first perform RRM measurements on the serving cell using initial information. The RRM measurement result can be RSRP, RSRQ, or other measurement results. Figure 6 Within the time range 1 shown, due to the activation of the BWP (such as...) of the terminal device Figure 6 The BWP#Y in the code does not include the RRM measurement reference signal. Therefore, the terminal device needs to interrupt the data transmission on the currently active BWP#Y according to GAP1 and switch to a frequency resource that includes the RRM measurement reference signal (such as...). Figure 6 The RRM measurement is completed using BWP#X. Within time range 1, as the terminal device moves from the center of the serving cell to the edge of the serving cell, the RRM measurement results gradually deteriorate. To ensure the effectiveness of potential cell handovers, starting from time range 2, the terminal device begins using the second information to perform RRM measurements on either non-serving cells or both serving and non-serving cells. Since the second measurement duration corresponding to GAP2 is longer than the first measurement duration corresponding to GAP1, it facilitates the terminal device in detecting more non-serving cells, making it easier to select a suitable cell during subsequent handovers. The terminal device can activate the use of the second information via the network device, or it can directly use the second information and then notify the network device through the uplink data transmission channel to begin performing RRM measurements using the second information.

[0178] Optionally, in this embodiment, the behavior of the terminal device during the first measurement period can be constrained to reduce the impact of the terminal device's behavior on the RRM measurement and improve the accuracy of the RRM measurement. That is, when the terminal device performs the RRM measurement during the first measurement period, it is implemented in the following manner:

[0179] In the first implementation, when the currently active BWP of the terminal device does not include the RRM measurement reference signal to be measured, the first measurement duration may include one or more of a first duration, a second duration, or a third duration. During the first duration, the second duration, and the third duration, the terminal device does not (expect) send physical uplink channels and physical uplink signals to the network device, and does not (expect) receive physical downlink channels and downlink signals from the network device.

[0180] The three durations are defined as follows: the first duration is the continuous transmission duration of the RRM measurement reference signal to be measured; the second duration is the preset duration before the start symbol of the RRM measurement reference signal; and the third duration is the preset duration after the end symbol of the RRM measurement reference signal. The preset duration can be less than or equal to 1 ms, for example, it can be 140 microseconds (μs), 500 μs, or one orthogonal frequency division multiplexing (OFDM) symbol; or the preset duration can be less than or equal to the minimum duration required for the terminal device to perform RF tuning. The specific values ​​of the second and third durations are not limited. For example, the second duration can be 140 μs, 500 μs, or one OFDM symbol; the third duration can also be 140 μs, 500 μs, or one OFDM symbol. The values ​​of the second and third durations can be the same or different. Within a first measurement duration, there may be one or more first durations, one or more second durations, or one or more third durations, without specific limitations.

[0181] The physical uplink channels here include the physical uplink control channel (PUCCH) and the physical uplink shared channel (PUSCH). The physical uplink signals include the sounding reference signal (SRS). The physical downlink channels include the physical downlink control channel (PDCCH), the physical downlink shared channel (PDSCH), the tracking reference signal (TRS), and the CSI-RS used for channel quality information (CQI) measurement.

[0182] In the second implementation, when the terminal device's currently activated BWP does not include the RRM measurement reference signal to be measured, the terminal device does not (expect) send physical uplink channels and physical uplink signals to the network device within the time range corresponding to the first measurement duration, and does not (expect) receive physical downlink channels and downlink signals from the network device.

[0183] Combining the first and second implementation methods described above, the following concrete example illustrates the first, second, and third durations included within the first measurement duration. For example, such as... Figure 7 As shown, it is assumed that within the first measurement duration, there are 4 SSBs used for RRM measurement, and the time distribution of the SSBs satisfies Figure 1 (e.g.) Figure 7 As shown in Figure 1), specifically, the OFDM symbol occupied by SSB1 is... Figure 7 The OFDM symbol indices 4 to 7 included in slot n are as follows: SIB2 occupies the following OFDM symbols: Figure 7 The OFDM symbol indices of 8 to 11 included in slot n are as follows: SIB3 occupies the following OFDM symbols: Figure 7 The OFDM symbol indices 2 to 5 included in slot n+1 are as follows: SIB4 occupies the following OFDM symbols: Figure 7 The OFDM symbol index included in slot n+1 is 6 to 9.

[0184] Combination Figure 7When the first implementation is adopted, when the terminal device performs RRM measurement in time slot n, the terminal device performs the following actions within time slot n: the first duration of OFDM symbol indices 4 to 11, the second duration before the symbol with OFDM symbol index 4, and the third duration after the symbol with OFDM symbol index 11. When the terminal device performs RRM measurement in time slot n+1, the terminal device does not (expect) send physical uplink channels and physical uplink signals to the network device, and does not (expect) receive physical downlink channels and downlink signals from the network device within time slot n+1: the first duration of OFDM symbol indices 2 to 9, the second duration before the symbol with OFDM symbol index 2, and the third duration after the symbol with OFDM symbol index 9.

[0185] When the second implementation is adopted, the terminal device does not (expect) send physical uplink channels and physical uplink signals to the network device on all OFDM symbols included in the first measurement duration (i.e., all OFDM symbols included in time slot n and time slot n+1), and does not (expect) receive physical downlink channels and downlink signals from the network device.

[0186] For example, such as Figure 7 As shown, within the first measurement duration, there are 4 SSBs used for RRM measurement, and the time distribution of the SSBs satisfies Figure 2. In Figure 2, the OFDM symbol occupied by SSB1 is... Figure 7 The OFDM symbol indices 2 to 5 included in slot n are as follows: SIB2 occupies the following OFDM symbols: Figure 7 The OFDM symbol indices of 8 to 11 included in slot n are as follows: SIB3 occupies the following OFDM symbols: Figure 7 The OFDM symbol indices 2 to 5 included in slot n+1 are as follows: SIB4 occupies the following OFDM symbols: Figure 7 The OFDM symbol index included in slot n+1 is 8 to 11.

[0187] Combination Figure 7When using the first implementation method, the terminal device includes the following time slots: OFDM symbol indices 2-5 (first duration), a preset duration before the symbol with OFDM symbol index 2 (second duration), a preset duration after the symbol with OFDM symbol index 5 (third duration), OFDM symbol indices 8-11 (first duration), a preset duration before the symbol with OFDM symbol index 8 (second duration), a preset duration after the symbol with OFDM symbol index 11 (third duration), OFDM symbol indices 2-5 (first duration), a preset duration before the symbol with OFDM symbol index 2 (second duration), a preset duration after the symbol with OFDM symbol index 5 (third duration), and OFDM symbol indices 8-11 (first duration), a preset duration before the symbol with OFDM symbol index 8 (second duration), a preset duration after the symbol with OFDM symbol index 5 (third duration), and so on. Within a preset duration (third duration) following the symbol with OFDM symbol index 11, the terminal device does not (expect) send physical uplink channels and physical uplink signals to the network device, nor does it (expect) receive physical downlink channels and downlink signals from the network device; or, within the preset duration (second duration) before the symbol with OFDM symbol index 2 to 11 included in time slot n, the preset duration (third duration) following the symbol with OFDM symbol index 11, the preset duration (second duration) following the symbol with OFDM symbol index 2 to 11 included in time slot n+1, and the preset duration (third duration) following the symbol with OFDM symbol index 11, the terminal device does not (expect) send physical uplink channels and physical uplink signals to the network device, nor does it (expect) receive physical downlink channels and downlink signals from the network device.

[0188] When the second implementation is adopted, the terminal device does not (expect) send physical uplink channels and physical uplink signals to the network device on all OFDM symbols included in the first measurement duration (i.e., all OFDM symbols included in time slot n and time slot n+1), and does not (expect) receive physical downlink channels and downlink signals from the network device.

[0189] It should be noted that, in the first implementation, the first duration can correspond to the duration of a continuously distributed SSB in time, such as the one mentioned above. Figure 7 When the time distribution of the SSB satisfies Figure 1, the first duration corresponds to time slot n, which includes OFDM symbols with indices 4 to 11. The first duration also corresponds to time slot n+1, which includes OFDM symbols with indices 2 to 9. It can be observed that in this case, the first measurement duration can include multiple first durations. Alternatively, [the following text is incomplete and requires further context]. Figure 7When the time distribution of SSB satisfies Figure 2, the first duration corresponds to OFDM symbols with OFDM symbol indices 2 to 5 included in time slot n, and also corresponds to OFDM symbols with OFDM symbol indices 8 to 11 included in time slot n, and also corresponds to OFDM symbols with OFDM symbol indices 2 to 5 included in time slot n+1, and also corresponds to OFDM symbols with OFDM symbol indices 8 to 11 included in time slot n+1. Alternatively, to simplify the implementation of the terminal device, the first duration can correspond to OFDM symbols with OFDM symbol indices 2 to 11 included in time slot n, and also corresponds to OFDM symbols with OFDM symbol indices 2 to 11 included in time slot n+1.

[0190] As can be seen from the foregoing description, in this embodiment of the application, the terminal device can determine the first information and the second information, and use the first information or the second information to perform RRM measurement.

[0191] In this implementation, the first measurement duration included in the first information is less than the second measurement duration included in the second information, and / or, the first measurement cycle included in the first information is greater than the second measurement cycle included in the second information. Through this implementation, different measurement configurations can be adapted to different measurement scenarios, thereby reducing data transmission discontinuities caused by measurement configurations and ensuring data transmission performance. Optionally, when the first measurement duration included in the first information is located in a first duration set, and the second measurement duration included in the second information is located in a second duration set, one implementation of the first measurement duration being less than the second measurement duration is: the measurement duration selected from the first duration set as the first measurement duration is less than the measurement duration selected from the second duration set as the second measurement duration; another implementation is: at least one measurement duration included in the first measurement duration set is less than all measurement durations included in the second measurement duration set. Optionally, when the first measurement period included in the first information is located in the first period set, and the second measurement period included in the second information is located in the second period set, one way to make the first measurement period greater than the second measurement period is: the measurement period selected from the first period set as the first measurement period is greater than the measurement period selected from the second period set as the second measurement period; another way to make it is: at least one measurement period included in the first period set is greater than all measurement periods included in the second period set.

[0192] In this application embodiment, the first information and the second information can also be applied in other ways. In one implementation, the first information and the second information correspond to different types of reference signals. Specifically, when performing RRM measurement based on the first type of reference signal, the first measurement period and / or the first measurement duration are used; when performing RRM measurement based on the second type of reference signal, the second measurement period and / or the second measurement duration are used.

[0193] In the embodiments of this application, different types of reference signals may include at least one of the following differences:

[0194] (1) The reference signals are different. For example, SSB is a first type of reference signal, and CSI-RS is a second type of reference signal.

[0195] (2) The reference signals are the same, but the time-domain density of the reference signal distribution is different. The time-domain density of the reference signal distribution can be, for example, the distribution period of the reference signal. For example, if the reference signal is CSI-RS and the period is 10ms or 40ms, then the CSI-RS with a period of 10ms is the first type of reference signal; the CSI-RS with a period of 40ms can be the second type of reference signal.

[0196] (3) The reference signals are the same, but the frequency ranges of the reference signal distribution are different. The frequency range of the reference signal distribution may include at least one of the following: the bandwidth of the frequency range corresponding to the reference signal, the density of the reference signal distribution in the frequency domain, and the frequency range corresponding to the reference signal.

[0197] Taking the different reference signals as an example, CSI-RS and SSB generally have different beams. For instance, CSI-RS allows for finer deployment direction compared to SSB. This means that when the terminal device moves, the measurement results based on CSI-RS change more significantly than those based on SSB. To ensure transmission performance, RRM measurements based on CSI-RS can be performed more frequently than those based on SSB. In this case, by introducing different first and second information, different measurement durations and cycles can be adapted for different types of reference signals, allowing for targeted optimization of the measurement process and ensuring the RRM measurement results. Furthermore, if RRM measurements are performed according to the measurement configuration corresponding to CSI-RS, it may lead to frequent interruptions in data transmission on the active BWP. Implementing the measurement configurations corresponding to CSI-RS and SSB separately can reduce the impact of SSB-based RRM measurements on data transmission interruptions.

[0198] In another implementation, in this embodiment, the number of beams measured by the terminal device using the first information differs from the number of beams measured using the second information. For example, when the number of beams is greater than a preset threshold, the second information can be used to perform RRM measurement; when the number of beams is less than or equal to the preset threshold, the first information can be used to perform RRM measurement. Different numbers of beams correspond to different measurement requirements. For example, when the terminal device is at the cell edge, it needs to detect more beams to find a more suitable cell for camping. In this case, the terminal device can use the second information to perform RRM measurement. However, when the terminal device is at the cell center, the probability of handover due to mobility is relatively low. Therefore, in this case, the terminal device only needs to detect a small number of beams. In this case, the terminal device can use the first information to perform RRM measurement. In the above implementation, the first information and the second information respectively satisfy the measurement requirements for measuring different numbers of beams.

[0199] It should be noted that, in the embodiments of this application, the first measurement duration included in the first information includes the RF tuning time. Optionally, the RF tuning time is 140μs, or 500μs, or the duration of one OFDM symbol. The OFDM symbol duration varies depending on the subcarrier spacing (SCS).

[0200] The RF tuning time included in the second measurement duration of the second information can be the same as or greater than the RF tuning time included in the first measurement duration.

[0201] It should be noted that by introducing multiple measurement configurations through the embodiments of this application, different measurement configurations can be used for different measurement needs, thereby improving RRM measurement efficiency and reducing the impact on business data. For example, as Figure 8 As shown, assuming the first information configured by the network device includes a first measurement duration of 2ms and the second information includes a second measurement duration of 6ms, through the embodiments of this application, since the terminal device uses the first information to perform RRM measurement, the interruption for activating BWP is at most 2ms each time. Compared with the interruption duration of 6ms caused by using the second information to perform RRM measurement, the interruption duration of data transmission can be significantly reduced, and the data transmission efficiency can be improved.
