Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a reference signal measurement method, apparatus and storage medium. Background Technology

[0002] During Layer 1 / Layer 2 Triggered Mobility (LTM), network devices can configure measurement interval (GAP) patterns for terminals. Based on the measurement GAP patterns, the terminals perform L1 measurements on reference signals from neighboring cells.

[0003] Currently, during LTM (Low-Terminal Measurement), the terminal supports L1 measurement based on the Synchronization Signal Block (SSB). Network devices can configure corresponding measurement gap patterns based on the relevant information transmitted by the SSB. The terminal then measures the SSBs of neighboring cells based on the measurement gap resources indicated by the measurement gap pattern.

[0004] However, the above measurement methods are mainly for SSB measurement. When other types of reference signals need to be measured, the above measurement methods are less flexible and may lead to problems such as excessive terminal measurement delay, waste of GAP resources and low system throughput.

[0165] Since terminal 11 operates in the current active downlink BWP, when the frequency range of the reference signal of cell B is outside the current active downlink BWP range of terminal 11, terminal 11 needs to measure the reference signal of cell B based on the measurement gap. That is, terminal 11 needs to reserve a period of time during which it cannot transmit or receive any data. During this period, terminal 11 can tune its receiver to the frequency point where the reference signal of cell B is located, thereby measuring the reference signal of cell B.

[0166] Network device 12 configures measurement gap and measurement gap pattern for terminal 11. Measurement gap pattern is a time mode configured by network device 12 for terminal 11. This time mode specifies the time periods during which terminal 11 can perform measurement operations, that is, the time periods during which terminal 11 is allowed to temporarily leave the current service frequency and switch to the frequency of cell B to measure the reference signal of cell B.

[0167] Measurement gaps are configured periodically. The parameters involved in the measurement gap pattern mainly include the measurement gap length (MGL) and the measurement gap repetition period (MGPR). For example, a measurement gap pattern is configured for a periodically transmitted synchronization signal block (SSB), where MGL = 6ms and MGPR = 40ms, indicating that each period is 40ms, and there is a 6ms duration within each period, which can be used to measure the SSB of cell B.

[0168] The relevant technologies define two types of measurement gaps: terminal-based measurement gaps (per-UE GAP) and frequency band-based measurement gaps (per-FR GAP), and provide 24 measurement gap patterns, each with corresponding MGL and MGRP. Furthermore, new measurement gap patterns are introduced for positioning functions. These two types of measurement gap patterns are only configured when positioning measurements are set, and can only be per-UE gaps.

[0169] Table 1 below shows the MGL and MGRP corresponding to each measurement GAP pattern:

[0170] Table 1

[0171]

[0172] As shown in Table 1, all measurement gaps are configured periodically, with a maximum of 6ms for MGL and a minimum of 20ms for MGRP. Furthermore, for per-UE gaps, only one measurement gap pattern can be configured for the terminal by the network device. For per-FR gaps, the network device can simultaneously configure independent measurement gap patterns for FR1 and FR2 for the terminal.

[0173] Further enhancements to the measurement gaps have been made, introducing three enhanced gap types for standalone (SA) scenarios: pre-configured measurement intervals (Pre-MG), concurrent measurement intervals (concurrent MG(s)), and network-controlled small gaps (NCSG). For terminals supporting Pre-MG, network devices can pre-configure one or more measurement gap patterns. When indicated by the network device or a specific trigger event occurs, the terminal only needs to activate or deactivate the pre-configured measurement gap pattern. For terminals supporting concurrent MG(s), network devices can configure multiple measurement gap patterns for the terminal, allowing the terminal to apply different measurement gap patterns to different measurements. For terminals supporting NCSG, when an idle radio frequency (RF) link is available, by configuring NCSG, the terminal can perform measurements without using the measurement gap, thereby reducing network load and increasing terminal throughput. The NCSG pattern includes Measurement Length (ML) and Visible Interruption Repetition Period (VIRP). ML represents the length of time for measuring within the same frequency / different frequency / different system. During this time, the terminal can simultaneously transmit uplink and downlink services. VIRP represents the period during which the Visible Interruption Length (VIL) occurs. VIL indicates that there will be an interruption to services during this period.

[0174] Table 2 below shows the ML and VIRP corresponding to NCSG patterns:

[0175] Table 2

[0176] NCSG graphic logo Length measurement (ML, in milliseconds) The interrupt repetition period (VIRP, in milliseconds) is as follows. 0 5 40 1 5 80 2 2 40 3 2 80 4 5 20 5 5 160 6 3 20 7 3 40 8 3 80 9 3 160 10 2 20 11 2 160 12 5 20 13 5 40 14 5 80 15 5 160 16 3 20 17 3 40 18 3 80 19 3 160 20 1 20 21 1 40 22 1 80 23 1 160

[0177] However, currently, L1 measurements for neighboring cells in LTM only support SSB-based measurements, and an optional L1 measurement capability based on measurement gaps has been introduced. For L1 measurements based on measurement gaps, only one gap pattern can be configured for each terminal by the network device at a time. Future LTM implementations may introduce measurements of different types of reference signals. Currently, L1 measurements for neighboring cells in LTM have low flexibility, and different transmission methods for reference signals may lead to wasted gap resources, reduced system throughput, and longer terminal measurement latency, especially for measurements of reference signals based on semi-persistent / aperiodic transmission methods, where these problems are more pronounced.

[0178] To illustrate with an example: Channel State Information Reference Signal (CSI-RS) used for mobility only supports periodic transmission, while CSI-RS used for beam management supports periodic, semi-persistent, and aperiodic transmission. If the system supports network devices configured to transmit reference signals in semi-persistent and aperiodic modes, but still uses measurement gaps periodically, the terminal will be unable to transmit data when some reference signals are not activated or transmitted, or when other measurements do not require gaps. This wastes gap resources and affects the overall system throughput.

[0179] Secondly, the configurable period for CSI-RS used for mobility is 4 / 5 / 10 / 20 / 40ms, while the configurable period for CSI-RS used for beam management is 4 / 5 / 8 / 10 / 16 / 20 / 32 / 40 / 64 / 80 / 160 / 320 / 640 time slots. Currently, the configurable periods in the measurement gap pattern do not adequately cover the configurable periods of different types of reference signal resources. Especially when some reference signal resources have periods of 8 / 16 / 32 / 64ms, the current gap period is not a multiple of the reference signal period. This results in some measurement gaps and the reference signal under test not overlapping, leading to resource waste, reduced throughput, and longer terminal measurement delays. The design of the NCSG pattern also faces the same problems as the measurement gap.

[0180] Based on this, embodiments of this application provide a reference signal measurement method that supports network devices configuring one or more GAPs and GAP patterns for terminals at a time to support the measurement of different types of reference signals. Furthermore, the GAPs configured by the network device include Pre-MG, which is only used when activated, thereby further improving the flexibility of the measurement. The solutions of embodiments of this application will be described below with reference to the accompanying drawings.

[0181] Figure 2 This is a flowchart of a reference signal measurement method provided in an embodiment of this application. The method is applied to a terminal, such as... Figure 2 As shown, the method includes:

[0182] S21, based on one or more GAPs and GAP patterns, measure the reference signals of neighboring cells; wherein, one or more GAPs include Pre-MG, and other GAPs besides Pre-MG in one or more GAPs include measurement GAPs or NCSGs.

[0183] Network devices can configure one or more GAPs for a terminal, as well as the GAP pattern for each GAP. The GAP pattern is used to indicate the time mode of the corresponding GAP, that is, the period during which the terminal is allowed to temporarily leave the current service frequency and switch to the frequency of the reference signal of the neighboring cell to measure the reference signal of the neighboring cell.

[0184] If the frequency range corresponding to the reference signal of a neighboring cell is not within the terminal's currently active downlink BWP, the terminal can measure the reference signal of the neighboring cell based on the GAP and GAP pattern configured by the network device. Since the terminal supports the network device to configure one or more GAPs and GAP patterns, when it is necessary to measure different reference signals of neighboring cells, the network device can configure GAPs and GAP patterns respectively according to information such as the transmission period and transmission duration of different reference signals.

[0185] Among them, the network device configures one or more GAPs for the terminal, including Pre-MG. Pre-MG is only used in the active state. When there is no need to measure the reference signal, Pre-MG can be deactivated, thereby reducing the waste of GAP resources.

[0186] Among the one or more GAPs configured by the network device for the terminal, if there are other GAPs besides Pre-MG, these other GAPs may include measurement GAPs or NCSGs. Measurement GAPs can be, for example, per-UE GAPs, per-FR GAPs, etc., and the measurement GAP pattern can be, for example, the pattern shown in Table 1. NCSG represents a small interval of network control when there is an idle RF link, and the NCSG pattern can be, for example, the pattern shown in Table 2.

[0187] The reference signal measurement method provided in this application involves the terminal measuring reference signals of neighboring cells based on one or more GAPs and GAP patterns configured by the network device for the terminal. The one or more GAPs include Pre-MG, and the other GAPs besides Pre-MG include measurement GAPs or NCSGs. Since the terminal supports configuring one or more GAPs and GAP patterns by the network device, it can use different GAPs and GAP patterns to measure different reference signals after introducing different reference signals. Compared to the current method of using a single measurement GAP to measure each reference signal, this reduces the terminal's measurement latency. Because the one or more GAPs include Pre-MG, which is only used in the active state, this reduces the waste of GAP resources and improves the flexibility of reference signal measurement.

[0188] Based on any of the above embodiments, the solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0189] Optionally, if the network device configures one or more GAPs for the terminal that only include Pre-MG, then Pre-MG is used to measure all reference signals of neighboring cells.

[0190] Optionally, if the network device configures one or more GAPs for the terminal, including Pre-MG and other GAPs, then Pre-MG is used to measure a first reference signal of a neighboring cell. The first reference signal is transmitted in an aperiodic transmission mode or a semi-persistent transmission mode. Other GAPs may include measurement GAPs or NCSGs, and the GAP patterns of other GAPs and other GAPs are used to measure other reference signals (e.g., SSB) besides the first reference signal.

[0191] Since the Pre-MG is used after activation, the terminal needs to activate the Pre-MG immediately to ensure it is in an active state. With the Pre-MG active, the terminal measures the first reference signal based on the Pre-MG's gap pattern.

[0192] Optionally, the terminal determines the first moment to activate Pre-MG based on the transmission time information of the first reference signal, meaning that the first moment and the transmission time information of the first reference signal are related in chronological order. The transmission time information of the first reference signal is used to indicate the time related to the transmission of the first reference signal, and may include, for example, the start time of the transmission of the first reference signal.

[0193] The transmission time information of the first reference signal may also be different depending on the transmission method of the first reference signal. The following will introduce the content of the transmission time information of the first reference signal when the transmission method of the first reference signal is a non-periodic transmission method and a semi-continuous transmission method, and the correlation between the transmission time information of the first moment and the first reference signal in the time signal sequence, with reference to the accompanying drawings.

[0194] If the first reference signal is transmitted in an aperiodic manner, the network device will send a first signaling message to the terminal. This first signaling message indicates that the first reference signal is about to be transmitted. Optionally, the first signaling message is downlink control information (DCI).

[0195] Figure 3 This is a schematic diagram illustrating the determination of the first moment under the aperiodic transmission mode provided in the embodiments of this application, as shown below. Figure 3As shown, the time when the terminal receives the first signaling sent by the network device is ta, wherein the first signaling is used to indicate the transmission of the first reference signal, or the first signaling is used to indicate the transmission of the first reference signal and the activation of Pre-MG.

[0196] If the first signaling is used to indicate the transmission of the first reference signal and the activation of Pre-MG, the terminal can activate Pre-MG after receiving the first signaling. The first moment is the moment when the terminal receives the first signaling, i.e. Figure 3 t in a Timing. In this case, the activation of Pre-MG and the start of transmitting the first reference signal coincide.

[0197] If the first signaling is used to indicate the transmission of the first reference signal, the network device also needs to issue Radio Resource Control (RRC) signaling, which is used to indicate the activation of Pre-MG. The first moment of activating Pre-MG is later than the moment the terminal receives the first signaling (i.e.,...). Figure 3 t in a The time is no later than the second time (i.e., the time of the second time). Figure 3 t in b The second time point is earlier than the first start time point of the first reference signal transmission, and the duration between the second time point and the first start time point is greater than or equal to the duration required for the RF link switching of the terminal.

[0198] like Figure 3 As shown, the first starting time is time t. c , time t c As the time-domain starting point of the first reference signal, the terminal needs to ensure that the measurement of the first reference signal begins at least from the first starting time. Since the terminal needs to perform RF link switching during the measurement of the first reference signal so that the receiver can tune to the frequency of the first reference signal, at least the time required for the terminal's RF link switching must be reserved before the first starting time. Therefore, the first time cannot be later than the second time.

[0199] In summary, when the transmission mode of the first reference signal is a non-periodic transmission mode, the transmission time information of the first reference signal includes the time when the terminal receives the first signaling, and / or the first start time of the transmission of the first reference signal. The correlation between the first time and the transmission time information is used to indicate that: the first time is the time when the terminal receives the first signaling; or, the first time is later than the time when the terminal receives the first signaling, but not later than the second time.

[0200] When the first reference signal is transmitted in an aperiodic transmission mode and the transmission of the first reference signal is complete, the terminal can deactivate Pre-MG. For example... Figure 3As shown, the time when the first reference signal transmission is completed is t. d The terminal can be at time t d To activate Pre-MG, you can also do so at time t. d Then activate Pre-MG (e.g.) Figure 3 t in e time).

[0201] The solution in this application embodiment addresses the case where the transmission mode of the first reference signal is a non-periodic transmission mode. By associating the first moment of activating Pre-MG with the transmission time information of the first reference signal in chronological order, Pre-MG is activated. Therefore, during the transmission of the first reference signal, the GAP pattern of Pre-MG can be used to measure the first reference signal. After the transmission of the first reference signal is completed, Pre-MG is activated, reducing the waste of GAP resources.

[0202] If the first reference signal is transmitted in a semi-persistent mode, the network device will send a second signaling message to the terminal. Optionally, the second signaling message is a Media Access Control-Control Element (MAC CE).

[0203] Figure 4 This is a schematic diagram illustrating the determination of the first moment under the semi-persistent transmission mode provided in the embodiments of this application, as shown below. Figure 4 As shown, the time when the terminal receives the second signaling sent by the network device is ta, wherein the second signaling is used to indicate the activation of the first reference signal, or the second signaling is used to indicate the activation of the first reference signal and the activation of Pre-MG.

[0204] If the second signaling is used to instruct the activation of the first reference signal and the activation of Pre-MG, the terminal can activate Pre-MG upon receiving the second signaling. The first moment is the moment the terminal receives the second signaling, i.e. Figure 4 t in a Timing. In this case, the timing of activating Pre-MG coincides with the timing of activating the first reference signal.

[0205] If the second signaling is used to indicate the activation of the first reference signal, the network device also needs to issue RRC signaling, which is used to indicate the activation of Pre-MG. The first moment of activating Pre-MG is later than the moment the terminal receives the second signaling (i.e., ...). Figure 4 t in a (time), and no later than the third time (i.e.) Figure 4 t in bThe third time point is earlier than the second start time point of the first activated first reference signal transmission, and the duration between the third time point and the second start time point is greater than or equal to the duration required for the terminal's RF link switching.

[0206] like Figure 4 As shown, the second starting time is time t. c , time t c As the time-domain starting point for the first activated reference signal, the terminal needs to ensure that it starts measuring the first reference signal at least from the second starting time. Since the terminal needs to switch the RF link during the measurement of the first reference signal so that the receiver can tune to the frequency of the first reference signal, at least the time required for the terminal's RF link switching needs to be reserved before the second starting time. Therefore, the first time cannot be later than the third time.

[0207] In summary, when the transmission mode of the first reference signal is semi-persistent, the transmission time information of the first reference signal includes the time when the terminal receives the second signaling, and / or the second start time of the first activated first reference signal transmission. The correlation between the first time and the transmission time information is used to indicate that: the first time is the time when the terminal receives the second signaling; or, the first time is later than the time when the terminal receives the second signaling, but not later than the third time.

[0208] Optionally, if the transmission mode of the first reference signal is semi-continuous transmission mode and the state of the first reference signal is deactivated, the terminal may deactivate Pre-MG.

[0209] Optionally, if the first reference signal is transmitted in a semi-persistent transmission mode, the network device can send indication information to the terminal. The terminal receives the indication information sent by the network device, which instructs the deactivation of the first reference signal and Pre-MG. Based on the indication information, the terminal deactivates the first reference signal and Pre-MG. In this case, the deactivation times of the first reference signal and Pre-MG are the same.

[0210] like Figure 4 As shown, the time when the state of the first reference signal switches to the deactivation state is t. d The terminal can be at time t d To activate Pre-MG, you can also do so at time t. d Then activate Pre-MG (e.g.) Figure 4 t in e time).

[0211] The solution in this application embodiment addresses the case where the transmission mode of the first reference signal is a semi-continuous transmission mode. By associating the first moment of activating Pre-MG with the transmission time information of the first reference signal in chronological order, Pre-MG is activated. Therefore, during the transmission of the first reference signal, the GAP pattern of Pre-MG can be used to measure the first reference signal. After the first reference signal is deactivated, Pre-MG is activated, reducing the waste of GAP resources.

[0212] In the above embodiments, the activation and deactivation of Pre-MG were described. The GAP pattern of Pre-MG will be described below.

[0213] In one possible implementation, the GAP pattern of the Pre-MG can be a first measurement GAP pattern, which is used to indicate the measurement interval length of the Pre-MG and the measurement interval repetition period of the Pre-MG.

[0214] Optionally, the first measurement GAP pattern can be any one of the 25 measurement GAP patterns exemplified in Table 1. Correspondingly, the measurement interval length of Pre-MG can be any one of the multiple measurement interval lengths exemplified in Table 1, and the measurement interval repetition period of Pre-MG can be any one of the multiple measurement interval repetition periods exemplified in Table 1.

[0215] Optionally, the measurement interval length of Pre-MG belongs to at least one first measurement interval length, and / or, the measurement interval repetition period of Pre-MG belongs to at least one first measurement interval repetition period; wherein, at least one first measurement interval length includes at least one of the following: 10ms, 20ms; at least one first measurement interval repetition period includes at least one of the following: 8ms, 16ms, 32ms, 64ms.

[0216] Optionally, at least one first measurement interval length and the multiple measurement interval lengths exemplified in Table 1 can constitute a set of measurement interval lengths, and the measurement interval length of Pre-MG can be any one of this set of measurement interval lengths.

[0217] Optionally, at least one first measurement interval repetition period and multiple measurement interval repetition periods exemplified in Table 1 can constitute a set of measurement interval repetition periods, and the measurement interval repetition period of Pre-MG can be any one of this set of measurement interval repetition periods.

[0218] In other words, at least one first measurement interval length and at least one first measurement interval repetition period can be combined with multiple measurement interval lengths and multiple measurement interval repetition periods in Table 1 to obtain a new measurement GAP pattern (i.e. a measurement GAP pattern different from that in Table 1), which serves as the GAP pattern for Pre-MG.

[0219] For example, the measurement interval length of Pre-MG is 6ms (belonging to the measurement interval lengths exemplified in Table 1), and the measurement interval repetition period of Pre-MG is 32ms (belonging to at least one first measurement interval repetition period); for example, the measurement interval length of Pre-MG is 10ms (belonging to at least one first measurement interval length), and the measurement interval repetition period of Pre-MG is 40ms (belonging to the measurement interval repetition period exemplified in Table 1); for example, the measurement interval length of Pre-MG is 6ms (belonging to the measurement interval lengths exemplified in Table 1), and the measurement interval repetition period of Pre-MG is 80ms (belonging to the measurement interval repetition period exemplified in Table 1); the measurement interval length of Pre-MG is 10ms (belonging to at least one first measurement interval length), and the measurement interval repetition period of Pre-MG is 64ms (belonging to at least one first measurement interval repetition period), and so on.

[0220] By adding at least one first measurement interval length and at least one first measurement interval repetition period, and combining them with the measurement interval length and measurement interval repetition period in the current measurement GAP pattern, a richer and more diverse range of measurement GAP patterns can be provided, thereby adapting to various types, transmission times, and transmission periods of reference signals and improving the flexibility of reference signal measurement.

[0221] In one possible implementation, the GAP pattern of the Pre-MG can be a first NCSG pattern, which is used to indicate the measurement length of the Pre-MG and the visible interruption repetition period of the Pre-MG.

[0222] Optionally, the first NCSG pattern can be any one of the 24 NCSG patterns shown in Table 2. Correspondingly, the measurement length of Pre-MG can be any one of the multiple measurement lengths shown in Table 2, and the visible interruption repetition period of Pre-MG can be any one of the multiple visible interruption repetition periods shown in Table 2.

[0223] Optionally, the measurement length of Pre-MG belongs to at least one first measurement length, and / or the visible interruption repetition period of Pre-MG belongs to at least one first visible interruption repetition period; wherein, at least one first measurement length includes at least one of the following: 9ms, 9.5ms, 19ms, 19.5ms; at least one first visible interruption repetition period includes at least one of the following: 8ms, 16ms, 32ms, 64ms.

[0224] Optionally, at least one first measurement length and multiple measurement lengths exemplified in Table 2 can constitute a set of measurement lengths, and the measurement length of Pre-MG can be any one of these measurement lengths.

[0225] Optionally, at least one first visible interrupt repeat cycle and multiple visible interrupt repeat cycles exemplified in Table 2 can constitute a set of visible interrupt repeat cycles, and the visible interrupt repeat cycle of Pre-MG can be any one of this set of visible interrupt repeat cycles.

[0226] In other words, at least one first measurement length and at least one first visible interruption repetition period can be combined with multiple measurement lengths and multiple visible interruption repetition periods in Table 2 to obtain a new NCSG pattern (i.e., a different NCSG pattern from that in Table 2) as the GAP pattern of Pre-MG.

[0227] For example, the measurement length of Pre-MG is 5ms (belonging to the measurement interval lengths exemplified in Table 2), and the visible interruption repetition period of Pre-MG is 32ms (belonging to at least one first visible interruption repetition period); for example, the measurement length of Pre-MG is 9ms (belonging to at least one first measurement length), and the visible interruption repetition period of Pre-MG is 40ms (belonging to the measurement interval repetition period exemplified in Table 2); for example, the measurement length of Pre-MG is 2ms (belonging to the measurement lengths exemplified in Table 2), and the visible interruption repetition period of Pre-MG is 80ms (belonging to the visible interruption repetition period exemplified in Table 2); the measurement length of Pre-MG is 19ms (belonging to at least one first measurement length), and the visible interruption repetition period of Pre-MG is 64ms (belonging to at least one first visible interruption repetition period), and so on.

[0228] By adding at least one first measurement length and at least one first visible interruption repetition period, and combining them with the measurement length and visible interruption repetition period in the current NCSG pattern, a richer variety of NCSG patterns can be provided, thereby adapting to various types, transmission times, and transmission periods of reference signals and improving the flexibility of reference signal measurement.

[0229] In the above embodiments, the GAP pattern of Pre-MG was introduced. The measurement scheme for the case where the network device is configured with multiple frequency points for the first reference signal will be introduced below.

[0230] Figure 5 A schematic diagram of the reference signal set provided in the embodiments of this application, as shown below. Figure 5 As shown, when the network device is configured to measure multiple frequency points for the first reference signal, the first reference signal includes reference signals at multiple frequency points, that is, the first reference signal is a set of reference signals. Figure 5 In the example of the first reference signal being the CSI-RS set, there are a total of 6 CSI-RS signals. The frequency points of CSI-RS1, CSI-RS2 and CSI-RS3 are frequency points 1 (f1), the frequency points of CSI-RS4 and CSI-RS5 are frequency points 2 (f2), and the frequency point of CSI-RS6 is frequency point 3 (f3).

[0231] In related technologies, only one frequency point can be measured within a single measurement gap, and the measurement interval length is also limited. Figure 6 A measurement schematic diagram of the reference signal set provided in the embodiments of this application, as shown below. Figure 6 As shown, according to the current measurement gap, only CSI-RS1, CSI-RS2 and CSI-RS3 measurements are supported within the measurement interval length, while CSI-RS4, CSI-RS5 and CSI-RS6 measurements cannot be performed.

[0232] If measurements are performed based on a measurement gap, and the terminal cannot complete measurements of multiple frequency points within a single measurement interval, it will result in a long measurement delay. This is especially true for reference signals using aperiodic / semi-persistent transmission methods, where resource transmission only occurs once; therefore, the terminal must wait until all reference signals in the reference signal set have been measured before it can report its findings. Figure 6 The example measurement method may prevent the terminal from completing measurements at all frequency points, thus failing to report successfully and affecting system throughput.

[0233] Based on this, embodiments of this application provide a measurement scheme to achieve the measurement of reference signals at all frequency points in the reference signal set in one operation.

[0234] In one possible implementation, when the network device is configured to measure multiple frequency points for the first reference signal, and the GAP pattern of the Pre-MG is the first measurement GAP pattern, the measurement interval length of the Pre-MG is greater than or equal to the sum of the first duration and the second duration.

[0235] or,

[0236] When the network device is configured to measure multiple frequency points for the first reference signal, and the GAP pattern of the Pre-MG is the first NCSG pattern, the measurement length of the Pre-MG is greater than or equal to the sum of the first duration and the second duration.

[0237] The first duration is the duration required to transmit reference signals at multiple frequency points, and the second duration is the total duration required for multiple RF link switching during the measurement of reference signals at multiple frequency points.

[0238] by Figure 6 For example, the first duration is the duration required to transmit CSI-RS1, CSI-RS2, CSI-RS3, CSI-RS4, CSI-RS5, and CSI-RS6, while the second duration is determined by the number of RF link switching required to transmit these multiple frequency reference signals and the duration of each RF link switching.

[0239] If the first reference signal includes reference signals at n frequencies, then an RF link switch needs to be performed once when the measurement is started, (n-1) RF link switches need to be performed during the measurement of the reference signals at n frequencies, and an RF link switch needs to be performed once after the measurement is completed. Therefore, a total of (n+1) RF link switches are required. Thus, the measurement interval length or measurement length of the Pre-MG satisfies the following equation (1):

[0240] T resource set + T RF_switch *(n+1) ≤ T0 (1)

[0241] Among them, T resource set T represents the first duration. RF_switch This indicates the time required to perform one RF link handover, where n represents the first reference signal including n frequency points, and T0 represents the measurement interval length of the Pre-MG (for the case where the GAP pattern of the Pre-MG is the first measurement GAP pattern) or the measurement length of the Pre-MG (for the case where the GAP pattern of the Pre-MG is the first NCSG pattern).

[0242] As can be seen, by using the above method, the measurement of reference signals at multiple frequency points can be completed within a measurement interval or a measurement length, thereby increasing the probability of the terminal successfully reporting and thus increasing the system throughput.

[0243] The following examples will further illustrate the solutions of the embodiments of this application.

[0244] In the following examples, the terminal is performing CSI-RS-based L1 measurements in TLM. Figure 7 This application provides a schematic diagram of inter-frequency measurement based on CSI-RS for neighboring cells, as shown in the embodiments. Figure 7 As shown, the serving cell BWP, serving cell CSI-RS, the terminal's current active downlink BWP, neighboring cell BWP, and neighboring cell CSI-RS are illustrated respectively. When the terminal performs L1 measurement based on CSI-RS in LTM, the frequency to be measured configured by the network device is not within the range of the terminal's current active downlink BWP, and the terminal can use the measurement GAP to perform L1 measurement.

[0245] Example 1: The CSI-RS transmission method is periodic transmission, and the CSI-RS GAP pattern is a new measurement GAP pattern (i.e., a GAP pattern different from the measurement GAP pattern in the example in Table 1).

[0246] The relevant parameter configurations in Example 1 are shown in Table 3 below:

[0247] Table 3

[0248]

[0249] As shown in Table 3, the network device is configured with two GAPs and GAP patterns for the terminal. The first GAP pattern 1 is used for measuring other types of reference signals (such as SSB), and the second GAP pattern 2 (a new measurement GAP pattern, which is different from the measurement GAP pattern in Table 1) is used for measuring CSI-RS.

[0250] The network device configures the first GAP (Gap Area) for the terminal using GAP pattern 1 (containing MGL and MGRP), which follows the measurement GAP pattern example in Table 1, with MGL and MGRP values ​​of 6ms and 20ms respectively. The network device configures the second GAP (Gap Area) for the terminal using GAP pattern 2, with MGL and MGRP values ​​of 6ms and 32ms respectively. Furthermore, the network device assigns priorities to the two GAPs separately; when a collision occurs between different measurements, the terminal only needs to perform the measurement using the higher-priority GAP pattern.

[0251] When performing measurements, the terminal will use the new GAP pattern for CSI-RS-based L1 measurements, while simultaneously using existing GAP patterns for other types of measurements. For details, please refer to [link to relevant documentation]. Figure 8 Examples.

[0252] Figure 8 A schematic diagram of reference signal measurement provided for embodiments of this application. Figure 1 ,like Figure 8As shown, in Example 1, the terminal measures the SSB of the neighboring cell based on GAP pattern 1. Figure 8 The example shows MGL = 6ms and MGRP = 20ms for GAP pattern 1. The terminal, based on GAP pattern 2, measures the CSI-RS of neighboring cells. Figure 8 The example shows that MGL=6ms and MGRP=32ms for GAP pattern 2.

[0253] like Figure 8 As shown, during the first measurement cycle, if a collision occurs between the measurement of SSB and the measurement of CSI-RS, the terminal can select the higher-priority GAP pattern for measurement based on the configured priority. For example, if the priority of GAP pattern 2 is higher than that of GAP pattern 1, the terminal can measure CSI-RS when a collision occurs, but not the SSB. When no collision occurs, the terminal measures both SSB and CSI-RS separately.

[0254] As can be seen from Example 1, by configuring multiple GAP patterns for the terminal, it is possible to adapt to the measurement of reference signals with different transmission cycles, thereby reducing the waste of GAP resources.

[0255] Example 2: The CSI-RS transmission mode is either aperiodic or semi-continuous transmission mode, and the CSI-RS GAP pattern is a new measurement GAP pattern (i.e., a GAP pattern different from the measurement GAP pattern in the example in Table 1).

[0256] The relevant parameter configurations in Example 2 are shown in Table 4 below:

[0257] Table 4

[0258]

[0259] As shown in Table 4, the network device configures two GAPs and GAP patterns for the terminal. The first GAP pattern 1 is used for measuring other types of reference signals (such as SSB), and the second GAP pattern 2 (Pre-MG) (a new measurement GAP pattern, which is different from the measurement GAP patterns in Table 1) is used for measuring CSI-RS.

[0260] The network device configures the first GAP (Gap) pattern 1 (containing MGL and MGRP) for the terminal using the measurement GAP pattern exemplified in Table 1, with MGL and MGRP of 6ms and 20ms respectively as an example. The Pre-MG GAP pattern 2 configured by the network device for the terminal has MGL and MGRP of 10ms and 80ms respectively. Furthermore, the network device will configure priorities for the two GAPs separately; when a collision occurs between different measurements, the terminal only needs to perform the measurement in the higher-priority GAP pattern.

[0261] When performing measurements, the terminal will use the new GAP pattern for CSI-RS-based L1 measurements, while simultaneously using existing GAP patterns for other types of measurements. For details, please refer to [link to relevant documentation]. Figures 9-11 Examples.

[0262] The first reference signal is a CSI-RS set, please refer to [link / reference]. Figure 5 For example, the CSI-RS set includes CSI-RS1, CSI-RS2, CSI-RS3, CSI-RS4, CSI-RS5, and CSI-RS6.

[0263] Figure 9 A schematic diagram of CSI-RS measurement based on Pre-MG provided for an embodiment of this application is shown below. Figure 9 As shown, taking non-periodic CSI-RS transmission as an example, the activation / deactivation of Pre-MG can be related to the transmission time information of the first reference signal in terms of time sequence. That is, when the network device notifies the terminal that it is about to send a CSI-RS via the first signaling (such as DCI signaling), the activation of Pre-MG can be triggered. The first moment of activating Pre-MG can be the moment when the terminal receives the first signaling, or it can be later than the moment when the first signaling is received, but it must not be later than the second moment, that is, 0.5ms before the time domain start point of the first CSI-RS in the CSI-RS set (0.5ms is the duration required for the terminal's RF link switching).

[0264] To enable measurements at multiple frequency points to be completed within a single measurement gap, based on equation (1) above, the measurement interval length of the Pre-MG must satisfy:

[0265] T CSI-RS resource set +T RF_switch *4≤T0 (2)

[0266] Among them, T CSI-RS resource set T is the total transmission time required to transmit the CSI-RS set (i.e., the first duration). RF_switchThis indicates the time required to perform one RF link handover. The CSI-RS set includes reference signals at three frequencies, and T0 represents the measurement interval length of the Pre-MG.

[0267] After the current CSI-RS transmission ends, the terminal can trigger the deactivation of Pre-MG. For example... Figure 9 As shown, during the time Pre-MG is activated, the MGL for CSI-RS-based L1 measurements is increased by 10 ms in the application. Figure 9 As can be seen from the example, the MGL of Pre-MG is greater than or equal to the sum of the first duration and the second duration.

[0268] If the resource configuration of the CSI-RS resource set is relatively dense, a shorter MGL can also be applied to it. The configuration in Table 4 is just one example.

[0269] During the measurement process, the terminal will use Pre-MG and the new Gap pattern to perform CSI-RS-based L1 measurements for LTM candidate cells. Simultaneously, the terminal will use existing Gap patterns for other types of measurements; details can be found in [link to relevant documentation]. Figure 10 and Figure 11 Examples.

[0270] Figure 10 A schematic diagram of reference signal measurement provided for embodiments of this application. Figure 2 ,like Figure 10 As shown, for the non-periodic transmission CSI-RS in Example 2, the terminal measures the SSB of neighboring cells based on GAP pattern 1. Figure 10 The example shows that MGL=6ms and MGRP=20ms for GAP pattern 1.

[0271] The terminal measures the CSI-RS of neighboring cells based on GAP pattern 2. Figure 10 The example shows MGL=10ms and MGRP=80ms for GAP pattern 2. Figure 10 As shown, in the first MGL of GAP pattern 2, since the Pre-MG is not activated, the inactive Pre-MG is not used for measurement, so CSI-RS is not measured in the first MGL.

[0272] After the network device notifies the terminal via DCI that a CSI-RS transmission is about to be sent, the terminal activates the Pre-MG. Therefore, within the second MGL of GAP pattern 2, the terminal can perform CSI-RS measurements. After the CSI-RS transmission is complete, the terminal can deactivate the Pre-MG, and the deactivated Pre-MG is no longer used for measurement.

[0273] Figure 11A schematic diagram of reference signal measurement provided for embodiments of this application. Figure 3 ,like Figure 11 As shown, for the semi-persistent transmission CSI-RS in Example 2, the terminal measures the SSB of neighboring cells based on GAP pattern 1. Figure 11 The example shows that MGL=6ms and MGRP=20ms for GAP pattern 1.

[0274] The terminal measures the CSI-RS of neighboring cells based on GAP pattern 2. Figure 11 The example shows MGL=10ms and MGRP=80ms for GAP pattern 2. Figure 11 As shown, after the network device instructs the terminal to activate CSI-RS via the second signaling, the terminal activates Pre-MG. Therefore, within the first MGL of GAP pattern 2, the terminal can measure the first activated CSI-RS. Since the period of CSI-RS is 40ms, the second activated CSI-RS does not have a corresponding GAP, so it is not measured. Within the second MGL of GAP pattern 2, the terminal can measure the third activated CSI-RS, as shown below. Figure 11 As shown, after the third CSI-RS transmission is completed, CSI-RS is deactivated, so the terminal can also deactivate Pre-MG.

[0275] As illustrated in Example 2, configuring multiple GAP patterns for the terminal allows for the measurement of reference signals with different transmission periods, reducing the waste of GAP resources. Simultaneously, the activation and deactivation of the Pre-MG improves the flexibility of reference signal measurement. By supporting measurements at multiple frequencies, it addresses the potential problem of not being able to complete measurements at all frequencies when multiple aperiodic or semi-continuous transmission reference signals are transmitted within a single MGL or ML, thereby improving terminal measurement efficiency and system throughput.

[0276] Example 3: CSI-RS uses a non-periodic or semi-persistent transmission mode. The network device only configures a GAP (i.e., Pre-MG) and GAP pattern for the terminal.

[0277] The relevant parameter configurations in Example 3 are shown in Table 5 below:

[0278] Table 5

[0279]

[0280] As shown in Table 5, the network equipment only configures Pre-MG and GAP patterns for the terminals. Therefore, Pre-MG and GAP patterns are used for measuring all reference signals in neighboring cells. In this case, the activation / deactivation rule for Pre-MG is as follows: Pre-MG is activated when any measurement type requiring GAP exists in the entire system. Pre-MG is deactivated only when no measurement type in the entire system requires GAP measurement. Specifically, the first moment of Pre-MG activation still needs to reserve at least 0.5ms of RF link switching time after the time domain start point of the reference signal requiring GAP measurement.

[0281] For reference signal measurements based on Pre-MG and GAP patterns, please refer to [reference needed]. Figure 12 and Figure 13 Examples.

[0282] Figure 12 A schematic diagram of reference signal measurement provided for embodiments of this application. Figure 4 ,like Figure 12 As shown, for the semi-persistent CSI-RS in Example 3, the terminal measures the semi-persistent CSI-RS based on the Pre-MG and GAP patterns, and also measures the SSB.

[0283] exist Figure 12 The example shows MGL=6ms and MGRP=20ms for the GAP pattern. Figure 12 As shown, in the first MGL of the GAP pattern, since there is no SSB transmission and CSI-RS is not activated, there is no need to activate Pre-MG, and the inactive Pre-MG will not be used for measurement.

[0284] Within the second MGL of the GAP pattern, although CSI-RS is not activated, SSB transmission exists, so Pre-MG needs to be activated and SSB measured.

[0285] Within the third and fourth MGLs of the GAP pattern, CSI-RS is activated, and SSB transmission also occurs. Therefore, the terminal measures SSB and CSI-RS based on Pre-MG.

[0286] like Figure 12 As shown, after the third CSI-RS transmission is completed, CSI-RS is deactivated, and there is no SSB transmission. Therefore, the terminal can also deactivate Pre-MG.

[0287] Figure 13 A schematic diagram of reference signal measurement provided for embodiments of this application. Figure 5 ,like Figure 13As shown, for the non-periodic transmission CSI-RS in Example 3, the terminal measures the CSI-RS based on the Pre-MG and GAP patterns, and also measures the SSB.

[0288] exist Figure 13 The example shows MGL=6ms and MGRP=20ms for the GAP pattern. Figure 13 As shown, in the first MGL of the GAP pattern, since there is neither SSB transmission nor CSI-RS distribution, there is no need to activate Pre-MG, and the inactive Pre-MG will not be used for measurement.

[0289] In the second MGL of the GAP pattern, although no CSI-RS is issued, there is SSB transmission, so Pre-MG needs to be activated and SSB needs to be measured.

[0290] Within the third MGL of the GAP pattern, after the network device notifies the terminal via DCI that CSI-RS is about to be sent, the terminal measures SSB and CSI-RS based on Pre-MG because of the sending of CSI-RS and the transmission of SSB.

[0291] Within the fourth MGL of the GAP pattern, although the CSI-RS transmission ends, the SSB transmission still occurs; therefore, the terminal measures the SSB based on the Pre-MG. For example... Figure 13 As shown, after the SSB transmission is completed, the terminal can deactivate Pre-MG.

[0292] As can be seen from Example 3, the activation and deactivation of Pre-MG can improve the flexibility of reference signal measurement.

[0293] Example 4: The CSI-RS transmission mode is either aperiodic or semi-continuous, and the CSI-RS GAP pattern is a new measurement GAP pattern (i.e., a GAP pattern different from the measurement GAP pattern in the example in Table 1).

[0294] The relevant parameter configurations in Example 4 are shown in Table 6 below:

[0295] Table 6

[0296]

[0297] As shown in Table 6, the network device configures two GAPs and GAP patterns for the terminal. The first GAP pattern 1 is used for measuring other types of reference signals (such as SSB), and the second GAP pattern 2 (Pre-MG) (a new measurement GAP pattern, which is different from the measurement GAP pattern in Table 1) is used for measuring CSI-RS.

[0298] The network device configures the first GAP (Gap) pattern 1 (containing MGL and MGRP) for the terminal using the measurement GAP pattern exemplified in Table 1, with MGL and MGRP values ​​of 6ms and 20ms respectively. The network device configures the Pre-MG (Gap for Memory Access) pattern 2 for the terminal with MGL and MGRP values ​​of 6ms and 32ms respectively. Furthermore, the network device assigns priorities to the two GAPs separately; when a collision occurs between different measurements, the terminal only needs to perform the measurement using the higher-priority GAP pattern.

[0299] When performing measurements, the terminal will use the new GAP pattern for CSI-RS-based L1 measurements, while simultaneously using existing GAP patterns for other types of measurements. For details, please refer to [link to relevant documentation]. Figures 14-15 Examples.

[0300] Figure 14 A schematic diagram of reference signal measurement provided for embodiments of this application. Figure 6 ,like Figure 14 As shown, the terminal measures the SSB of the neighboring cell based on GAP pattern 1. For the CSI-RS of semi-persistent transmission in Example 4, the terminal measures the CSI-RS of semi-persistent transmission based on Pre-MG and GAP pattern 2.

[0301] exist Figure 14 The example shows MGL=6ms and MGRP=20ms for GAP pattern 2. Figure 14 As shown, in the first MGL of the GAP pattern, since CSI-RS is not activated, there is no need to activate Pre-MG, and the unactivated Pre-MG will not be used for measurement.

[0302] After the network device instructs the terminal to activate CSI-RS via the second signaling, the terminal activates Pre-MG. Therefore, within the second MGL of GAP pattern 2, the terminal can measure the first activated CSI-RS, and within the third MGL of GAP pattern 2, the terminal can measure the second activated CSI-RS. For example... Figure 14 As shown, after the second CSI-RS transmission is completed, CSI-RS is deactivated, so the terminal can also deactivate Pre-MG.

[0303] Figure 15 A schematic diagram of reference signal measurement provided for embodiments of this application. Figure 7 ,like Figure 15As shown, the terminal measures the SSB of the neighboring cell based on GAP pattern 1. For the non-periodic transmission CSI-RS in Example 4, the terminal measures the non-periodic transmission CSI-RS based on Pre-MG and GAP pattern 2.

[0304] like Figure 15 As shown, in the first MGL of GAP pattern 2, since there is no CSI-RS issued, there is no need to activate Pre-MG, and the inactive Pre-MG will not be used for measurement.

[0305] After the network device notifies the terminal via DCI that a CSI-RS transmission is about to be sent, the terminal activates the Pre-MG. Therefore, within the second MGL of GAP pattern 2, the terminal can perform CSI-RS measurements. After the CSI-RS transmission is complete, the terminal can deactivate the Pre-MG, and the deactivated Pre-MG is no longer used for measurement.

[0306] As shown in Example 4, by configuring multiple GAP patterns for the terminal, it is possible to adapt to the measurement of reference signals with different transmission periods, thus reducing the waste of GAP resources. Simultaneously, by activating and deactivating Pre-MG, the flexibility of reference signal measurement is improved, thereby increasing terminal measurement efficiency and system throughput.

[0307] Example 5: The CSI-RS transmission mode is either aperiodic or semi-persistent, and the CSI-RS GAP pattern is a new NCSG pattern (i.e., a GAP pattern different from the NCSG pattern in the example in Table 2).

[0308] The relevant parameter configurations in Example 5 are shown in Table 7 below:

[0309] Table 7

[0310]

[0311]

[0312] As shown in Table 7, the network device configures two GAPs and GAP patterns for the terminal. The first GAP pattern 1 is used for measuring other types of reference signals (such as SSB). The second GAP (Pre-MG) pattern 2 is a new NCSG pattern (i.e., a different NCSG pattern from the NCSG pattern in Table 2) used for measuring CSI-RS.

[0313] The network device configures the first GAP (Gap) pattern 1 (containing MGL and MGRP) for the terminal using the measurement GAP pattern exemplified in Table 1, with MGL and MGRP values ​​of 3.5ms and 20ms respectively. In the Pre-MG GAP pattern 2 configured by the network device for the terminal, ML and VIRP values ​​are 5ms and 32ms respectively. Furthermore, the network device will configure priorities for the two GAPs separately; when a collision occurs between different measurements, the terminal only needs to perform the measurement using the higher-priority GAP pattern.

[0314] When performing measurements, the terminal will use the new GAP pattern for CSI-RS-based L1 measurements, while simultaneously using existing GAP patterns for other types of measurements. For details, please refer to [link to relevant documentation]. Figures 16-17 Examples.

[0315] Figure 16 A schematic diagram of reference signal measurement provided for embodiments of this application. Figure 8 ,like Figure 16 As shown, the terminal measures the SSB of the neighboring cell based on GAP pattern 1. For the CSI-RS of semi-persistent transmission in Example 5, the terminal measures the CSI-RS of semi-persistent transmission based on Pre-MG and GAP pattern 2.

[0316] exist Figure 16 The example shows GAP pattern 2 with ML = 5ms and MGRP = 32ms. For example... Figure 16 As shown, in the first ML of GAP pattern 2, since CSI-RS is not activated, there is no need to activate Pre-MG, and the unactivated Pre-MG will not be used for measurement.

[0317] After the network device instructs the terminal to activate CSI-RS via the second signaling, the terminal activates Pre-MG. Therefore, within the second ML of GAP pattern 2, the terminal can measure the first activated CSI-RS, and within the third ML of GAP pattern 2, the terminal can measure the second activated CSI-RS. For example... Figure 16 As shown, after the second CSI-RS transmission is completed, CSI-RS is deactivated, so the terminal can also deactivate Pre-MG.

[0318] Figure 17 A schematic diagram of reference signal measurement provided for embodiments of this application. Figure 9 ,like Figure 17 As shown, the terminal measures the SSB of the neighboring cell based on GAP pattern 1. For the non-periodic transmission CSI-RS in Example 4, the terminal measures the non-periodic transmission CSI-RS based on Pre-MG and GAP pattern 2.

[0319] like Figure 17 As shown, in the first ML of GAP pattern 2, since there is no CSI-RS issued, there is no need to activate Pre-MG, and the unactivated Pre-MG will not be used for measurement.

[0320] After the network device notifies the terminal via DCI that CSI-RS is about to be transmitted, the terminal activates Pre-MG. Therefore, within the second ML of GAP pattern 2, the terminal can perform CSI-RS measurements. After the CSI-RS transmission is complete, the terminal can deactivate Pre-MG, and the deactivated Pre-MG is no longer used for measurement.

[0321] As shown in Example 5, by configuring multiple NCSG patterns for the terminal, it is possible to adapt to the measurement of reference signals with different transmission periods, reducing the waste of GAP resources. Simultaneously, by activating and deactivating Pre-MG, the flexibility of reference signal measurement is improved, thereby increasing terminal measurement efficiency and system throughput.

[0322] In summary, the solutions of this application provide a method for a terminal to support L1 measurements based on Pre-MG for neighboring cells. The network device can configure one or more measurement gaps (GAPs) for the terminal, enabling the terminal to support L1 measurements based on various types and configurations of reference signals. When the first reference signal is configured as a semi-persistent transmission mode / aperiodic transmission, the terminal can activate the Pre-MG by activating the correlation between the first moment of the Pre-MG and the transmission time information of the first reference signal in terms of temporal order. This allows the terminal to perform L1 measurements of neighboring cells only in the activated MGL or ML, thereby improving network configuration flexibility, reducing GAP resource waste, and increasing system throughput. Furthermore, this application also provides new measurement gap patterns and new NCSG patterns, enabling the solution to adapt to reference signal resources of various transmission modes and configurations. By introducing new MGRP and VIRP, the problem of excessive terminal measurement delay and resource waste caused by the configuration period of the reference signal not being a multiple of the measurement gap period is solved, improving network configuration flexibility and system throughput. The introduction of new MGL and ML, and the support for terminals to complete measurements of multiple frequency points within one MGL or ML, solves the problem that it may be impossible to complete measurements of all frequency points when a set of reference signals with non-periodic or semi-continuous transmission of multiple frequency points is transmitted within one MGL or ML, thereby improving terminal measurement efficiency and system throughput.

[0323] Figure 18 Schematic diagram of the reference signal measuring device provided in the embodiments of this application Figure 1 ,like Figure 18As shown, the device includes: a memory 1820, a transceiver 1800, and a processor 1810.

[0324] The memory 1820 is used to store computer programs; the transceiver 1800 is used to send and receive data under the control of the processor 1810; the processor 1810 is used to read the computer program stored in the memory 1820 and perform the following operations:

[0325] Based on one or more GAPs and GAP patterns, the reference signals of neighboring cells are measured;

[0326] One or more GAPs include Pre-MG, and other GAPs besides Pre-MG include Measurement GAPs or NCSGs.

[0327] In one possible implementation, Pre-MG is used to measure a first reference signal of a neighboring cell, the first reference signal being transmitted in an aperiodic transmission mode or a semi-persistent transmission mode.

[0328] In one possible implementation, for Pre-MG, reference signals of neighboring cells are measured based on one or more GAPs and GAP patterns, including:

[0329] Pre-MG is activated at the first moment, wherein the transmission time information of the first moment and the first reference signal are related in terms of time sequence;

[0330] With the Pre-MG active, the first reference signal is measured based on the GAP pattern of the Pre-MG.

[0331] In one possible implementation, the first reference signal is transmitted in an aperiodic transmission mode, and the processor is further configured to perform the following operations:

[0332] Receive a first signaling message sent by a network device, the first signaling message being used to indicate the transmission of a first reference signal, or the first signaling message being used to indicate the transmission of a first reference signal and activation of Pre-MG;

[0333] The transmission time information includes the time when the terminal receives the first signaling and / or the first start time of the transmission of the first reference signal.

[0334] In one possible implementation, the association is used to indicate:

[0335] The first moment is the moment when the terminal receives the first signaling;

[0336] or,

[0337] The first moment is later than the moment when the terminal receives the first signaling, but no later than the second moment;

[0338] The second time point is earlier than the first start time point, and the duration between the second time point and the first start time point is greater than or equal to the duration required for the terminal's RF link to switch.

[0339] In one possible implementation, the first reference signal is transmitted in a semi-persistent transmission mode, and the processor is further configured to perform the following operations:

[0340] The receiver receives a second signaling message sent by the network device, the second signaling message being used to indicate the activation of the first reference signal, or the second signaling message being used to indicate the activation of both the first reference signal and the Pre-MG;

[0341] The transmission time information includes the time when the terminal receives the second signaling, and / or the second start time of the transmission of the first activated first reference signal.

[0342] In one possible implementation, the association is used to indicate:

[0343] The first moment is the moment when the terminal receives the second signaling;

[0344] or,

[0345] The first moment is later than the moment when the terminal receives the second signaling, but no later than the third moment;

[0346] The third time point is earlier than the second start time point, and the duration between the third time point and the second start time point is greater than or equal to the duration required for the terminal's RF link to switch.

[0347] In one possible implementation, the GAP pattern of the Pre-MG is a first measurement GAP pattern, which is used to indicate the measurement interval length of the Pre-MG and the measurement interval repetition period of the Pre-MG.

[0348] or,

[0349] The GAP pattern of the Pre-MG is the first NCSG pattern, which is used to indicate the measurement length of the Pre-MG and the visible interruption repetition period of the Pre-MG.

[0350] In one possible implementation, the measurement interval length of Pre-MG belongs to at least one first measurement interval length, and / or, the measurement interval repetition period of Pre-MG belongs to at least one first measurement interval repetition period;

[0351] Wherein, at least one first measurement interval length includes at least one of the following: 10ms, 20ms; at least one first measurement interval repetition period includes at least one of the following: 8ms, 16ms, 32ms, 64ms.

[0352] In one possible implementation, the measurement length of the Pre-MG belongs to at least one first measurement length, and / or, the visible interruption repetition period of the Pre-MG belongs to at least one first visible interruption repetition period;

[0353] Wherein, at least one first measurement length includes at least one of the following: 9ms, 9.5ms, 19ms, 19.5ms; at least one first visible interruption repetition period includes at least one of the following: 8ms, 16ms, 32ms, 64ms.

[0354] In one possible implementation, when the network device is configured to measure multiple frequency points for the first reference signal, and the GAP pattern of the Pre-MG is the first measurement GAP pattern, the measurement interval length of the Pre-MG is greater than or equal to the sum of the first duration and the second duration.

[0355] or,

[0356] When the network device is configured to measure multiple frequency points for the first reference signal, and the GAP pattern of the Pre-MG is the first NCSG pattern, the measurement length of the Pre-MG is greater than or equal to the sum of the first duration and the second duration.

[0357] The first duration is the duration required to transmit reference signals at multiple frequency points, and the second duration is the total duration required for multiple RF link switching during the measurement of reference signals at multiple frequency points.

[0358] In one possible implementation, the processor is also configured to perform one of the following operations:

[0359] If the transmission mode of the first reference signal is aperiodic and the transmission of the first reference signal is complete, then activate Pre-MG.

[0360] When the transmission mode of the first reference signal is semi-continuous transmission mode and the state of the first reference signal is deactivated, the Pre-MG is deactivated;

[0361] When the transmission mode of the first reference signal is semi-persistent transmission mode, the system receives the indication information sent by the network device; based on the indication information, the system deactivates the first reference signal and Pre-MG.

[0362] Among them, Figure 18In this context, the bus architecture can include any number of interconnected buses and bridges, specifically linking various circuits together, such as one or more processors represented by processor 1810 and memory represented by memory 1820. The bus architecture can also link together various other circuits, such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. The bus interface provides an interface. The transceiver 1800 can be multiple components, including transmitters and receivers, providing a unit for communicating with various other devices over a transmission medium, including wireless channels, wired channels, optical fibers, etc. For different user equipment, the user interface 1830 can also be an interface capable of connecting external or internal devices, including but not limited to keypads, displays, speakers, microphones, joysticks, etc.

[0363] The processor 1810 is responsible for managing the bus architecture and general processing, while the memory 1820 can store the data used by the processor 1810 during operation.

[0366] It should be noted that the reference signal measuring device provided in this application embodiment can implement all the method steps implemented by the method embodiment with the execution subject as a terminal, and can achieve the same technical effect. Here, the parts that are the same as those in the method embodiment and the beneficial effects will not be described in detail.
