Description

Reference signal measurement method, device and storage medium

[0002] The present disclosure relates to the field of communication technology, and more particularly, to a reference signal measurement method, device and storage medium. BACKGROUND

[0003] In a layer 1 / layer 2 triggered mobility (L1 / L2-Triggered Mobility, LTM) process, a network device can configure a measurement gap (GAP) pattern for a terminal, and the terminal performs L1 measurement on a reference signal of a neighbor cell based on the measurement GAP pattern.

[0004] Currently, in the LTM process, the terminal supports L1 measurement based on a synchronization signal block (Synchronization Signal Block, SSB), and the network device can configure a corresponding measurement GAP pattern according to related information of SSB transmission. The terminal performs measurement on the SSB of the neighbor cell based on the measurement GAP resource indicated by the measurement GAP pattern.

[0005] However, the above measurement method is mainly for measuring SSB, and when other types of reference signals need to be measured, the flexibility of the above measurement method is low, which may cause problems such as too long terminal measurement delay, waste of GAP resources, and low system throughput.

For example, the network device according to the embodiments of the present disclosure can be an evolved network device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture, etc., and can also be a home evolved base station (HeNB), a relay node, a femto, a pico, a network test device, etc., which is not limited in the embodiments of the present disclosure. In some network structures, the network device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be arranged geographically apart.

[0161] The network device and the terminal device can each use one or more antennas for Multi Input Multi Output (MIMO) transmission, which can be Single User MIMO (SU-MIMO) or Multiple User MIMO (MU-MIMO). According to the shape and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or can be diversity transmission or precoding transmission or beamforming transmission, etc.

[0162] First, an application scenario suitable for the embodiments of the present disclosure is introduced in combination with FIG. 1.

[0163] FIG. 1 is a schematic diagram of an application scenario provided by the embodiments of the present disclosure, as shown in FIG. 1, the current serving cell of the terminal 11 is cell A, and cell B is a neighboring cell of cell A. The terminal 11 can measure the reference signal of cell B, and then decide whether to switch from cell A to cell B based on the measurement result.

[0164] In FIG. 1, a bandwidth part (BWP) of cell A and a BWP of cell B are respectively illustrated. The cell A is a current serving cell of the terminal 11, and a current active downlink BWP of the terminal 11 belongs to the BWP of the cell A. A frequency domain range corresponding to a reference signal of the cell B is within the BWP of the cell B.

[0165] Since the terminal 11 works in the current active downlink BWP, when the frequency domain range of the reference signal of the cell B is not within the range of the current active downlink BWP of the terminal 11, the terminal 11 needs to measure the reference signal of the cell B based on a measurement GAP. That is, the terminal 11 needs to reserve a period of time in which the terminal 11 cannot perform any data transmission or reception, and the terminal 11 can switch the receiver to the frequency point of the reference signal of the cell B to measure the reference signal of the cell B.

[0166] The network device 12 configures the measurement GAP and a measurement GAP pattern for the terminal 11. The measurement GAP pattern is a time mode configured by the network device 12 for the terminal 11, which specifies time periods in which the terminal 11 can perform measurement operations, i.e., time periods in which the terminal 11 is allowed to temporarily leave the current serving frequency point and switch to the frequency point of the cell B to measure the reference signal of the cell B.

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

[0168] In the related art, two types of measurement GAPs are defined, i.e., a per-UE GAP and a per-FR GAP, and 24 measurement GAP patterns are given, each of which has a corresponding MGL and MGRP. In addition, new measurement GAP patterns are introduced for positioning functions, and these two measurement GAP patterns are only configured when positioning measurement is configured, and can only be per-UE GAPs.

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

[0170] Table 1

[0171] As shown in Table 1, all measurement GAPS are periodically configured, the MGL is maximally 6 ms, and the MGRP is minimally 20 ms. In addition, for per-UE Gap, only one measurement GAP pattern can be configured by the network device for the terminal. For per-FR GAP, the network device can simultaneously configure the terminal with independent measurement GAP patterns for FR1 and FR2.

[0172] Further enhancements are made for measurement GAPS, and the types of enhanced GAPS of pre-configured measurement intervals (Pre-configured MG, Pre-MG), concurrent measurement intervals (concurrent MG(s)), and network-controlled small intervals (Network Controlled Small Gap, NCSG) are introduced for standalone (SA) scenarios. For terminals supporting Pre-MG, the network device can pre-configure one or more measurement GAP patterns for the terminal, and only need to activate or deactivate the pre-configured measurement GAP pattern when the network device indicates or a specific trigger event occurs. For terminals supporting concurrent MG(s), the network device can configure multiple measurement GAP patterns for the terminal, and the terminal can apply different measurement GAP patterns to different measurements. For terminals supporting NCSG, when there is an idle radio frequency (RF) link, the terminal can not use the measurement GAP for measurement by configuring the NCSG, thereby reducing network load and improving terminal throughput. The NCSG pattern contains a measurement length (ML) and a visible interruption repetition period (VIRP), the ML represents the time length for measuring the same frequency / different frequency / different system, and the terminal can simultaneously perform uplink and downlink service transmission during this period, and the VIRP represents the period of the occurrence of the visible interruption length (VIL), and the VIL represents the time period during which there will be an interruption impact on the service.

[0173] The following Table 2 shows the ML and VIRP corresponding to the NCSG pattern:

[0174] Table 2

[0175] However, the L1 measurement for the neighbor cell in the current LTM only supports SSB-based measurement, and an optional L1 measurement capability based on measurement GAP is introduced. For the L1 measurement based on the measurement GAP, only one GAP pattern is configured for the terminal by the network device. In the subsequent LTM, the measurement of different types of reference signals can be introduced, the flexibility of the L1 measurement for the neighbor cell in the current LTM is low, and the transmission mode of different types of reference signals can cause certain GAP resource waste, system throughput reduction, and longer terminal measurement delay problems, especially for the measurement of reference signals based on the semi-persistent transmission mode / non-periodic transmission mode.

[0176] Taking an example for illustration: the channel state information reference signal (CSI-RS) for mobility only supports periodic transmission, while the CSI-RS for beam management supports periodic, semi-persistent, and non-periodic transmission. If the system supports the transmission of reference signals in semi-persistent transmission mode and non-periodic transmission mode by the network device, the measurement GAP is still used periodically, which can cause the terminal to be unable to perform data transmission in the case that some reference signals are not activated or transmitted, and other measurements do not require GAP, thereby causing GAP resource waste and affecting the throughput of the entire system.

[0177] Secondly, the configurable period of the CSI-RS for mobility is 4 / 5 / 10 / 20 / 40 ms, while the configurable period of the CSI-RS for beam management is 4 / 5 / 8 / 10 / 16 / 20 / 32 / 40 / 64 / 80 / 160 / 320 / 640 slots. The configurable period in the measurement GAP pattern cannot well cover the configurable period of different types of reference signal resources, especially when the period of some reference signal resources is 8 / 16 / 32 / 64 ms, the current GAP period and the period of the reference signal do not have a multiple relationship, which will cause part of the measurement GAP and the to-be-measured reference signal to be unable to overlap, also causing resource waste and throughput reduction problems, and also causing longer terminal measurement delay. For the design of the NCSG pattern, the same problem as the measurement GAP also exists.

[0178] Based on this, the embodiments of the present disclosure provide a reference signal measurement method, which supports the network device to configure one or more GAPs and GAP patterns for the terminal at a time, to support the measurement of different types of reference signals, and the GAP configured by the network device includes a Pre-MG, which is only used when activated, thereby further improving the flexibility of the measurement. The scheme of the embodiments of the present disclosure will be introduced below in combination with the drawings.

[0179] FIG. 2 is a flowchart of a reference signal measurement method provided by an embodiment of the present disclosure, which is applied to a terminal. As shown in FIG. 2, the method comprises the following steps.

[0180] S21, measuring the reference signal of the neighbor cell based on one or more GAPs and a GAP pattern of the one or more GAPs; wherein the one or more GAPs comprise a Pre-MG, and the other GAPs in the one or more GAPs other than the Pre-MG comprise a measurement GAP or a NCSG.

[0181] The network device can configure one or more GAPs and a GAP pattern of each GAP for the terminal. The GAP pattern is used to indicate the time pattern of the corresponding GAP, that is, the period in which the terminal is allowed to temporarily leave the current serving frequency point and switch to the frequency point of the reference signal of the neighbor cell to measure the reference signal of the neighbor cell.

[0182] If the frequency domain range corresponding to the reference signal of the neighbor cell is not within the current active downlink BWP of the terminal, the terminal can measure the reference signal of the neighbor cell based on the GAP and the GAP pattern configured by the network device. Since the terminal supports the network device to configure one or more GAPs and a GAP pattern, when different reference signals of the neighbor cell need to be measured, the network device can configure the GAP and the GAP pattern according to the transmission period, the transmission time length and other information of different reference signals.

[0183] Among the one or more GAPs configured by the network device for the terminal, the Pre-MG is used only in the active state, and the Pre-MG can be deactivated in the case where the reference signal does not need to be measured, thereby reducing the waste of GAP resources.

[0184] Among the one or more GAPs configured by the network device for the terminal, if there are other GAPs other than the Pre-MG, the other GAPs can include a measurement GAP or a NCSG. The measurement GAP can be, for example, a per-UE GAP, a per-FR GAP, and the like, and the measurement GAP pattern of the measurement GAP can be, for example, the pattern shown in Table 1. The NCSG represents a network-controlled small interval when there is an idle RF link, and the NCSG pattern of the NCSG can be, for example, the pattern shown in Table 2.

[0185] The reference signal measurement method provided by the embodiments of the present disclosure is as follows: after the network device configures one or more GAPS and a GAP pattern for the terminal, the terminal measures the reference signals of the neighboring cells based on the one or more GAPS and the GAP pattern. The one or more GAPS include a Pre-MG, and the other GAPS in the one or more GAPS include a measurement GAP or a NCSG. Since the terminal supports the network device to configure one or more GAPS and a GAP pattern, after introducing different reference signals, the terminal can use different GAPS and GAP patterns to measure different reference signals, which can reduce the measurement delay of the terminal compared with the current use of a single measurement GAP to measure each reference signal. Since the one or more GAPS include a Pre-MG, the Pre-MG is only used in the active state, thereby reducing the waste of GAP resources and improving the flexibility of reference signal measurement.

[0186] The schemes of the embodiments of the present disclosure are described in detail below with reference to the drawings.

[0187] Optionally, if the one or more GAPS configured by the network device for the terminal only include a Pre-MG, the Pre-MG is used for measuring all reference signals of the neighboring cells.

[0188] Optionally, if the one or more GAPS configured by the network device for the terminal include a Pre-MG and other GAPS, the Pre-MG is used for measuring a first reference signal of the neighboring cells, and the transmission mode of the first reference signal is aperiodic transmission mode or semi-persistent transmission mode. The other GAPS can include a measurement GAP or a NCSG, and the other GAPS and the GAP pattern of the other GAPS are used for measuring other reference signals (such as SSB) other than the first reference signal.

[0189] Since the Pre-MG is used after being activated, the terminal needs to activate the Pre-MG at a first time to make the Pre-MG in the active state for the Pre-MG. In the case that the Pre-MG is in the active state, the terminal measures the first reference signal based on the GAP pattern of the Pre-MG.

[0190] Optionally, the terminal determines the first time to activate the Pre-MG based on the transmission time information of the first reference signal, that is, the first time and the transmission time information of the first reference signal have a correlation in the time sequence. The transmission time information of the first reference signal is used to indicate the time related to the transmission of the first reference signal, which can include the start time of the transmission of the first reference signal.

[0191] The transmission manner of the first reference signal is different, and the transmission time information of the first reference signal can also be different. The content of the transmission time information of the first reference signal and the association relationship between the first time and the transmission time information of the first reference signal in time sequence will be introduced below in combination with the drawings in the case that the transmission manner of the first reference signal is aperiodic transmission manner and semi-persistent transmission manner.

[0192] If the transmission manner of the first reference signal is aperiodic transmission manner, the network device will send the first signaling to the terminal, and the first signaling is used to indicate the transmission of the first reference signal. The network device indicates the terminal that the first reference signal will be sent out soon through the first signaling. Optionally, the first signaling is downlink control information (DCI).

[0193] FIG. 3 is a schematic diagram for determining the first time in the aperiodic transmission manner provided by the embodiment of the present disclosure. As shown in FIG. 3, the time when the terminal receives the first signaling sent by the network device is t a , 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 the Pre-MG.

[0194] If the first signaling is used to indicate the transmission of the first reference signal and the activation of the Pre-MG, the terminal can activate the Pre-MG after receiving the first signaling, and the first time is the time when the terminal receives the first signaling, that is, t a in FIG. 3. In this case, the time when the Pre-MG is activated and the time when the first reference signal is sent out are consistent.

[0195] If the first signaling is used to indicate the transmission of the first reference signal, the network device also needs to send the radio resource control (RRC) signaling, and the RRC signaling is used to indicate the activation of the Pre-MG. The first time when the Pre-MG is activated is later than the time when the terminal receives the first signaling (that is, t a in FIG. 3), and is not later than the second time (that is, t b in FIG. 3). The second time is earlier than the first starting time of the transmission of the first reference signal, and the time length between the second time and the first starting time is greater than or equal to the time length required for the RF link switching of the terminal.

[0196] As shown in FIG. 3, the first starting time is t c , the time t cThe time domain starting point of the first reference signal needs to be ensured by the terminal to start measuring the first reference signal from the first starting time. Because the terminal needs to switch the RF link during the measurement of the first reference signal, so that the receiver is directed to the frequency point of the first reference signal, therefore, at least the time required for the terminal to switch the RF link needs to be reserved before the first starting time, and therefore the first time cannot be later than the second time.

[0197] In summary, for the case that the transmission mode of the first reference signal is the aperiodic 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 starting time of the transmission of the first reference signal. The association 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, and is not later than the second time.

[0198] In the case that the transmission mode of the first reference signal is the aperiodic transmission mode and the transmission of the first reference signal is completed, the terminal can deactivate the Pre-MG. As shown in FIG. 3, the time when the transmission of the first reference signal is completed is t d , the terminal can deactivate the Pre-MG at time t d , or deactivate the Pre-MG after time t d (For example, at time t e in FIG. 3).

[0199] The scheme of the embodiment of the present disclosure, for the case that the transmission mode of the first reference signal is the aperiodic transmission mode, the first time of activating the Pre-MG is associated with the transmission time information of the first reference signal in the time sequence, to activate the Pre-MG, so that the GAP pattern of the Pre-MG can be used to measure the first reference signal during the transmission of the first reference signal, and the Pre-MG is deactivated after the transmission of the first reference signal is completed, thereby reducing the waste of GAP resources.

[0200] If the transmission mode of the first reference signal is the semi-persistent transmission mode, the network device will send the second signaling to the terminal. Optionally, the second signaling is a media access control-control element (MAC CE).

[0201] FIG. 4 is a schematic diagram for determining the first time in the semi-persistent transmission mode provided by the embodiment of the present disclosure, as shown in FIG. 4, the time when the terminal receives the second signaling sent by the network device is t a , wherein the second signaling is used to indicate to activate the first reference signal, or the second signaling is used to indicate to activate the first reference signal and activate the Pre-MG.

[0202] If the second signaling is used to indicate to activate the first reference signal and activate the Pre-MG, the terminal can activate the Pre-MG after receiving the second signaling, and the first time point is the time point at which the terminal receives the second signaling, that is, t a in FIG. 4. In this case, the time point of activating the Pre-MG and the time point of activating the first reference signal are consistent.

[0203] If the second signaling is used to indicate to activate the first reference signal, the network device also needs to issue RRC signaling to indicate to activate the Pre-MG. The first time point of activating the Pre-MG is later than the time point at which the terminal receives the second signaling (that is, t a in FIG. 4), and is not later than a third time point (that is, t b in FIG. 4). The third time point is earlier than a second starting time point of the first transmission of the first reference signal, and the time length between the third time point and the second starting time point is greater than or equal to the time length required for RF link switching of the terminal.

[0204] As shown in FIG. 4, the second starting time point is t c , and t c is the time domain starting point of the first activated first reference signal. The terminal needs to ensure that the measurement on the first reference signal is started at least from the second starting time point. Since the terminal needs to perform RF link switching during the measurement on the first reference signal, so that the receiver is directed to the frequency point of the first reference signal, at least the time length required for RF link switching of the terminal needs to be reserved before the second starting time point, and therefore the first time point cannot be later than the third time point.

[0205] In summary, for the case where the transmission mode of the first reference signal is a semi-persistent transmission mode, the transmission time information of the first reference signal includes the time point at which the terminal receives the second signaling, and / or the second starting time point of the first transmission of the first reference signal. The association relationship between the first time point and the transmission time information is used to indicate that the first time point is the time point at which the terminal receives the second signaling, or the first time point is later than the time point at which the terminal receives the second signaling, and is not later than the third time point.

[0206] Optionally, in the case where the transmission mode of the first reference signal is a semi-persistent transmission mode and the state of the first reference signal is a deactivated state, the terminal can deactivate the Pre-MG.

[0207] Optionally, in the case that the transmission mode of the first reference signal is a semi-persistent transmission mode, the network device can send indication information to the terminal, and correspondingly, the terminal receives the indication information sent by the network device, the indication information being used to indicate to deactivate the first reference signal and the Pre-MG, and the terminal deactivates the first reference signal and the Pre-MG based on the indication information. In this case, the time points of deactivating the first reference signal and the Pre-MG are the same.

[0208] As shown in FIG. 4, the time point of switching the state of the first reference signal to the deactivated state is t d , the terminal can deactivate the Pre-MG at the time point t d , or can deactivate the Pre-MG after the time point t d ( e.g., the time point t e in FIG. 4).

[0209] The scheme of the embodiments of the present disclosure, in the case that the transmission mode of the first reference signal is a semi-persistent transmission mode, activates the Pre-MG by associating the first time point of activating the Pre-MG with the transmission time information of the first reference signal in the time sequence, so that the first reference signal can be measured by using the GAP pattern of the Pre-MG during the transmission of the first reference signal, and the Pre-MG is deactivated after the first reference signal is deactivated, thereby reducing the waste of GAP resources.

[0210] In the above embodiments, the activation and deactivation of the Pre-MG are introduced, and the GAP pattern of the Pre-MG will be introduced below.

[0211] In a possible implementation, the GAP pattern of the Pre-MG can be a first measurement GAP pattern, the first measurement GAP pattern being used to indicate the measurement interval length of the Pre-MG and the measurement interval repetition period of the Pre-MG.

[0212] Optionally, the first measurement GAP pattern can be any one of the 25 measurement GAP patterns shown in Table 1, and correspondingly, the measurement interval length of the Pre-MG can be any one of the plurality of measurement interval lengths shown in Table 1, and the measurement interval repetition period of the Pre-MG can be any one of the plurality of measurement interval repetition periods shown in Table 1.

[0213] Optionally, the measurement interval length of the Pre-MG belongs to at least one first measurement interval length, and / or the measurement interval repetition period of the Pre-MG belongs to at least one first measurement interval repetition period; wherein the at least one first measurement interval length includes at least one of the following: 10 ms, 20 ms; and the at least one first measurement interval repetition period includes at least one of the following: 8 ms, 16 ms, 32 ms, 64 ms.

[0214] Optionally, the at least one first measurement gap length and the plurality of measurement gap lengths exemplified in Table 1 can constitute a measurement gap length set, and the measurement gap length of the Pre-MG can be any one of the measurement gap length set.

[0215] Optionally, the at least one first measurement gap repetition period and the plurality of measurement gap repetition periods exemplified in Table 1 can constitute a measurement gap repetition period set, and the measurement gap repetition period of the Pre-MG can be any one of the measurement gap repetition period set.

[0216] That is, the at least one first measurement gap length and the at least one first measurement gap repetition period can be combined with the plurality of measurement gap lengths and the plurality of measurement gap repetition periods in Table 1 to obtain a new measurement GAP pattern (i.e., a measurement GAP pattern different from Table 1) as the GAP pattern of the Pre-MG.

[0217] For example, the measurement gap length of the Pre-MG is 6 ms (belonging to the measurement gap length exemplified in Table 1), and the measurement gap repetition period of the Pre-MG is 32 ms (belonging to the at least one first measurement gap repetition period); for example, the measurement gap length of the Pre-MG is 10 ms (belonging to the at least one first measurement gap length), and the measurement gap repetition period of the Pre-MG is 40 ms (belonging to the plurality of measurement gap repetition periods exemplified in Table 1); for example, the measurement gap length of the Pre-MG is 6 ms (belonging to the measurement gap length exemplified in Table 1), and the measurement gap repetition period of the Pre-MG is 80 ms (belonging to the plurality of measurement gap repetition periods exemplified in Table 1); for example, the measurement gap length of the Pre-MG is 10 ms (belonging to the at least one first measurement gap length), and the measurement gap repetition period of the Pre-MG is 64 ms (belonging to the at least one first measurement gap repetition period), and so on.

[0218] By adding the at least one first measurement gap length and the at least one first measurement gap repetition period, and combining them with the measurement gap length and the measurement gap repetition period in the current measurement GAP pattern, more diverse measurement GAP patterns can be provided, thereby adapting to various types, various transmission times, and various transmission periods of the reference signal, and improving the flexibility of the reference signal measurement.

[0219] In a possible implementation, the GAP pattern of the Pre-MG can be a first NCSG pattern, and the first NCSG pattern is used to indicate the measurement length of the Pre-MG and the visible interruption repetition period of the Pre-MG.

[0220] Optionally, the first NCSG pattern can be any one of the 24 NCSG patterns shown in Table 2, and correspondingly, the measurement length of the Pre-MG can be any one of the measurement lengths shown in Table 2, and the visible interruption repetition period of the Pre-MG can be any one of the visible interruption repetition periods shown in Table 2.

[0221] Optionally, 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; wherein the at least one first measurement length comprises at least one of the following: 9ms, 9.5ms, 19ms, 19.5ms; and the at least one first visible interruption repetition period comprises at least one of the following: 8ms, 16ms, 32ms, 64ms.

[0222] Optionally, the at least one first measurement length and the measurement lengths shown in Table 2 can constitute a measurement length set, and the measurement length of the Pre-MG can be any one of the measurement length set.

[0223] Optionally, the at least one first visible interruption repetition period and the visible interruption repetition periods shown in Table 2 can constitute a visible interruption repetition period set, and the visible interruption repetition period of the Pre-MG can be any one of the visible interruption repetition period set.

[0224] That is, the at least one first measurement length and the at least one first visible interruption repetition period can be combined with the measurement lengths and the visible interruption repetition periods in Table 2 to obtain a new NCSG pattern (i.e., an NCSG pattern different from Table 2) as the GAP pattern of the Pre-MG.

[0225] For example, the measurement length of the Pre-MG is 5ms (belongs to the measurement interval length shown in Table 2), and the visible interruption repetition period of the Pre-MG is 32ms (belongs to the at least one first visible interruption repetition period); for example, the measurement length of the Pre-MG is 9ms (belongs to the at least one first measurement length), and the visible interruption repetition period of the Pre-MG is 40ms (belongs to the measurement interval repetition period shown in Table 2); for example, the measurement length of the Pre-MG is 2ms (belongs to the measurement length shown in Table 2), and the visible interruption repetition period of the Pre-MG is 80ms (belongs to the visible interruption repetition period shown in Table 2); the measurement length of the Pre-MG is 19ms (belongs to the at least one first measurement length), and the visible interruption repetition period of the Pre-MG is 64ms (belongs to the at least one first visible interruption repetition period), and so on.

[0226] By adding at least one first measurement length and at least one first visible interruption repetition period, which are combined with the measurement length and the visible interruption repetition period in the current NCSG pattern, more diverse NCSG patterns can be provided, thereby adapting to reference signals of various types, various transmission times, and various transmission periods, and improving the flexibility of reference signal measurement.

[0227] In the above embodiment, the GAP pattern of the Pre-MG is introduced, and the measurement scheme in the case where the network device configures multiple frequency point measurements for the first reference signal will be introduced.

[0228] FIG. 5 is a schematic diagram of a reference signal set provided by the embodiment of the present disclosure, as shown in FIG. 5, in the case where the network device configures multiple frequency point measurements for the first reference signal, the first reference signal includes multiple frequency point reference signals, that is, the first reference signal is a reference signal set. In FIG. 5, taking the first reference signal as a CSI-RS set as an example, a total of 6 CSI-RS signals are included, wherein the frequency points of CSI-RS1, CSI-RS2, and CSI-RS3 are frequency point 1 (f1), the frequency points of CSI-RS4 and CSI-RS5 are frequency point 2 (f2), and the frequency point of CSI-RS6 is frequency point 3 (f3).

[0229] In the related art, only one frequency point can be measured in one measurement GAP, and the measurement interval length is also limited. FIG. 6 is a schematic diagram of measurement of a reference signal set provided by the embodiment of the present disclosure, as shown in FIG. 6, according to the current measurement GAP, only the measurement of CSI-RS1, CSI-RS2, and CSI-RS3 is supported within the measurement interval length, and the measurement of CSI-RS4, CSI-RS5, and CSI-RS6 cannot be performed.

[0230] If the terminal cannot complete the measurement of multiple frequency points in one measurement interval length when measuring based on the measurement GAP, a longer measurement delay will be caused. Especially for the reference signal in the aperiodic transmission mode / semi-persistent transmission mode, there is only one opportunity for transmission of the resource, and therefore the terminal needs to wait until all the reference signals in the reference signal set are measured before reporting. Therefore, the measurement mode in the example of FIG. 6 can cause the terminal to be unable to complete the measurement of all the frequency points, and therefore cannot successfully report, thereby affecting the system throughput.

[0231] Based on this, the embodiment of the present disclosure provides a measurement scheme to realize the measurement of all the frequency points of the reference signal in the reference signal set at one time.

[0232] In a possible implementation, in a case where the network device configures measurement of 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 time length and the second time length.

[0233] Or,

[0234] In a case where the network device configures measurement of 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 time length and the second time length.

[0235] The first time length is a time length required for transmitting the reference signals of the multiple frequency points, and the second time length is a total time length required for performing RF link switching multiple times in the process of measuring the reference signals of the multiple frequency points.

[0236] Taking FIG. 6 as an example, the first time length is a time length required for transmitting the CSI-RS1, the CSI-RS2, the CSI-RS3, the CSI-RS4, the CSI-RS5, and the CSI-RS6, and the second time length is determined by the number of times of RF link switching required for transmitting the reference signals of the multiple frequency points and the time length of each time of RF link switching.

[0237] If the first reference signal includes n reference signals of frequency points, one RF link switching needs to be performed when starting measurement, (n-1) RF link switchings need to be performed in the process of measuring the n reference signals of frequency points, and one RF link switching needs to be performed after completing measurement, so a total of (n+1) RF link switchings need to be performed. Therefore, the measurement interval length of the Pre-MG or the measurement length of the Pre-MG satisfies the following formula (1): T resourceset +T RF_switch *(n+1)≤T0 (1)

[0238] The first time length is represented by T resourceset The time length required for performing one RF link switching is represented by T RF_switch n represents that the first reference signal includes n reference signals of frequency points, and T0 represents the measurement interval length of the Pre-MG (in a case where the GAP pattern of the Pre-MG is the first measurement GAP pattern) or the measurement length of the Pre-MG (in a case where the GAP pattern of the Pre-MG is the first NCSG pattern).

[0239] It can be seen that, by the above manner, the measurement of the reference signals of the multiple frequency points can be completed in one measurement interval length or one measurement length, so that the probability of successful reporting of the terminal can be improved, and thus the system throughput can be improved.

[0240] The scheme of the embodiments of the present disclosure is further introduced below with several specific examples.

[0241] In the following examples, the terminal performs CSI-RS-based L1 measurement in TLM is taken as an example. FIG. 7 is a schematic diagram of inter-frequency measurement based on CSI-RS of a neighbor cell provided by the embodiments of the present disclosure, as shown in FIG. 7, the serving cell BWP, the serving cell CSI-RS, the current active downlink BWP of the terminal, the neighbor cell BWP and the neighbor cell CSI-RS are respectively illustrated. When the terminal performs CSI-RS-based L1 measurement in TLM, the terminal supports the network device to configure the to-be-measured frequency not in the range of the current active downlink BWP of the terminal, and supports the terminal to perform L1 measurement by using the measurement GAP.

[0242] Example one: the transmission mode of the CSI-RS is periodic transmission, and the GAP pattern of the CSI-RS is a new measurement GAP pattern (i.e., a GAP pattern different from the measurement GAP pattern in Table 1).

[0243] The related parameter configuration in example one is shown in Table 3 as follows:

[0244] Table 3

[0245] Based on Table 3, the network device configures two GAPs and GAP patterns for the terminal. The GAP pattern 1 of the first GAP is used for measurement of other types of reference signals (such as SSB), and the GAP pattern 2 (a new measurement GAP pattern, i.e., a measurement GAP pattern different from the measurement GAP pattern in Table 1) of the second GAP is used for measurement of the CSI-RS.

[0246] The GAP pattern 1 (including MGL and MGRP) of the first GAP configured by the network device for the terminal adopts the measurement GAP pattern in Table 1. Taking the MGL and MGRP of the first GAP as 6 ms and 20 ms respectively as an example. The MGL and MGRP in the GAP pattern 2 of the second GAP configured by the network device for the terminal are 6 ms and 32 ms respectively. In addition, the network device configures priorities for the two GAPs, and when collision of different measurements occurs, the terminal only needs to perform measurement in the GAP pattern with high priority.

[0247] When the terminal performs measurement, it will use the new GAP pattern for CSI-RS-based L1 measurement, and at the same time, the terminal will use the existing GAP pattern for other types of measurement. For details, refer to the example of FIG. 8.

[0248] FIG. 8 is a schematic diagram of reference signal measurement according to an embodiment of the present disclosure. As shown in FIG. 8, for example one, the terminal measures the SSB of the neighboring cell based on the GAP pattern 1. In FIG. 8, the MGL of the GAP pattern 1 is 6 ms and the MGRP is 20 ms. The terminal measures the CSI-RS of the neighboring cell based on the GAP pattern 2. In FIG. 8, the MGL of the GAP pattern 2 is 6 ms and the MGRP is 32 ms.

[0249] As shown in FIG. 8, the measurement of the SSB and the measurement of the CSI-RS collide in the first measurement period. The terminal can select the GAP pattern with higher priority to perform measurement according to the configured priority. For example, if the priority of the GAP pattern 2 is higher than the priority of the GAP pattern 1, the terminal can perform measurement on the CSI-RS when collision occurs and does not perform measurement on the SSB. When no collision occurs, the terminal performs measurement on the SSB and the CSI-RS respectively.

[0250] According to example one, by configuring multiple GAP patterns for the terminal, the terminal can adapt to the measurement of reference signals with different transmission periods and reduce the waste of GAP resources.

[0251] Example two: the transmission mode of the CSI-RS is the aperiodic transmission mode or the semi-persistent transmission mode, and the GAP pattern of the CSI-RS is a new measurement GAP pattern (i.e., a GAP pattern different from the measurement GAP pattern in Table 1).

[0252] The related parameter configuration in example two is shown in Table 4.

[0253] Table 4

[0254] According to Table 4, the network device configures two GAPs and GAP patterns for the terminal. The GAP pattern 1 of the first GAP is used for measurement of other types of reference signals (e.g., SSB), and the GAP pattern 2 (a new measurement GAP pattern, i.e., a measurement GAP pattern different from the measurement GAP pattern in Table 1) of the second GAP (a Pre-MG) is used for measurement of the CSI-RS.

[0255] The GAP pattern 1 (including MGL and MGRP) of the first GAP configured by the network device for the terminal adopts the measurement GAP pattern in Table 1. For example, the MGL and MGRP of the first GAP are 6 ms and 20 ms respectively. The MGL and MGRP in the GAP pattern 2 of the Pre-MG configured by the network device for the terminal are 10 ms and 80 ms respectively. In addition, the network device configures a priority for each of the two GAPs. When collision of different measurements occurs, the terminal only needs to perform measurement in the GAP pattern with higher priority.

[0256] When the terminal performs the measurement, the new GAP pattern is used for the CSI-RS-based L1 measurement, and the terminal uses the existing GAP pattern for other types of measurement. For details, refer to the examples in FIGS. 9-11.

[0257] The first reference signal is a CSI-RS set. For details, refer to the example in FIG. 5. The CSI-RS set includes CSI-RS1, CSI-RS2, CSI-RS3, CSI-RS4, CSI-RS5, and CSI-RS6.

[0258] FIG. 9 is a schematic diagram of CSI-RS measurement based on Pre-MG according to an embodiment of the present disclosure. As shown in FIG. 9, taking the aperiodic transmission of CSI-RS as an example, the trigger of activation / deactivation of Pre-MG can have a correlation in time sequence with the transmission time information of the first reference signal, that is, the Pre-MG can be triggered to be activated after the network device notifies the terminal of the upcoming CSI-RS through the first signaling (such as DCI signaling). The first time of activating the Pre-MG can be the time when the terminal receives the first signaling, or can be later than the time when the terminal receives the first signaling, but cannot be later than the second time, that is, 0.5 ms before the time domain starting point of the first CSI-RS in the CSI-RS set (0.5 ms is the time length required for the RF link switching of the terminal).

[0259] To complete the measurement of multiple frequency points within one measurement gap, based on the above formula (1), the measurement interval length of the Pre-MG satisfies: T CSI-RSresourceset +T RF_switch *4≤T0 (2)

[0260] Wherein, T CSI-RSresourceset is the total transmission time length (i.e., the first time length) required for transmitting the CSI-RS set, T RF_switch represents the time length required for performing one RF link switching, the CSI-RS set includes reference signals of 3 frequency points, and T0 represents the measurement interval length of the Pre-MG.

[0261] After the transmission of the CSI-RS ends, the terminal can trigger the deactivation of the Pre-MG. As shown in FIG. 9, within the time when the Pre-MG is activated, a new 10 ms MGL is applied for the CSI-RS-based L1 measurement. As can be seen from the example in FIG. 9, the MGL of the Pre-MG is greater than or equal to the sum of the first time length and the second time length.

[0262] If the resource configuration in the CSI-RS resource set is relatively dense, a shorter MGL can also be applied to it. The configuration in Table 4 is only an example.

[0263] When the terminal performs measurement, the terminal will use the Pre-MG and the new Gap pattern to perform CSI-RS-based L1 measurement for LTM candidate cells, while the terminal will use the existing Gap pattern to perform other types of measurement, which can be seen from the examples of FIG. 10 and FIG. 11.

[0264] FIG. 10 is a schematic diagram of reference signal measurement two provided by an embodiment of the present disclosure, as shown in FIG. 10, for the non-periodic transmission CSI-RS in example two, the terminal measures the SSB of the neighbor cell based on the GAP pattern 1, and in FIG. 10, the MGL of the GAP pattern 1 is 6 ms and the MGRP is 20 ms.

[0265] The terminal measures the CSI-RS of the neighbor cell based on the GAP pattern 2, and in FIG. 10, the MGL of the GAP pattern 2 is 10 ms and the MGRP is 80 ms. As shown in FIG. 10, in the first MGL of the GAP pattern 2, since the Pre-MG is not activated, the non-activated Pre-MG is not used for measurement, so the CSI-RS is not measured in the first MGL.

[0266] After the network device informs the terminal through the DCI that the CSI-RS will be issued soon, the terminal activates the Pre-MG, so in the second MGL of the GAP pattern 2, the terminal can measure the CSI-RS. After the transmission of the CSI-RS is completed, the terminal can deactivate the Pre-MG, and the deactivated Pre-MG is not used for measurement.

[0267] FIG. 11 is a schematic diagram of reference signal measurement three provided by an embodiment of the present disclosure, as shown in FIG. 11, for the semi-persistent transmission CSI-RS in example two, the terminal measures the SSB of the neighbor cell based on the GAP pattern 1, and in FIG. 11, the MGL of the GAP pattern 1 is 6 ms and the MGRP is 20 ms.

[0268] The terminal measures the CSI-RS of the neighboring cell based on the GAP pattern 2. The MGL of the GAP pattern 2 is 10 ms and the MGRP is 80 ms, as shown in FIG. 11. As shown in FIG. 11, after the network device instructs the terminal to activate the CSI-RS through the second signaling, the terminal activates the Pre-MG, and thus the terminal can measure the first activated CSI-RS within the first MGL of the GAP pattern 2. Since the period of the CSI-RS is 40 ms, the second activated CSI-RS does not have a corresponding GAP, and thus the second activated CSI-RS is not measured. Within the second MGL of the GAP pattern 2, the terminal can measure the third activated CSI-RS, as shown in FIG. 11. After the transmission of the third CSI-RS is completed, the CSI-RS is deactivated, and thus the terminal can also deactivate the Pre-MG.

[0269] It can be learned from Example Two that by configuring multiple GAP patterns for the terminal, the measurement of reference signals with different transmission periods can be adapted, and the waste of GAP resources is reduced. Meanwhile, by activating and deactivating the Pre-MG, the flexibility of reference signal measurement is improved. By supporting the measurement of multiple frequency points, the problem that all frequency point measurements cannot be completed when multiple frequency point aperiodic or semi-persistent transmission reference signals are transmitted within one MGL or ML can be solved, and the terminal measurement efficiency and system throughput are improved.

[0270] Example Three: The transmission mode of the CSI-RS is an aperiodic transmission mode or a semi-persistent transmission mode, and the network device only configures one GAP (i.e., the Pre-MG) and a GAP pattern for the terminal.

[0271] The related parameter configuration in Example Three is shown in Table 5.

[0272] Table 5

[0273] It can be learned from Table 5 that the network device only configures the Pre-MG and the GAP pattern for the terminal, and thus the Pre-MG and the GAP pattern are used for the measurement of all reference signals of the neighboring cell. In this case, the activation / deactivation rule of the Pre-MG is that the Pre-MG is activated when there is any measurement type in the entire system that needs a GAP. The Pre-MG is deactivated only when all types of measurements in the entire system do not need a measurement GAP. The first time point of activating the Pre-MG still needs to reserve at least 0.5 ms of RF link switching time after the time domain starting point of the reference signal that needs a Gap measurement.

[0274] The measurement of the reference signal based on the Pre-MG and the GAP pattern can be referred to the examples shown in FIG. 12 and FIG. 13.

[0275] FIG. 12 is a schematic diagram four of reference signal measurement provided by the embodiment of the present disclosure, as shown in FIG. 12, for the CSI-RS of the semi-persistent transmission in example three, the terminal measures the CSI-RS of the semi-persistent transmission based on the Pre-MG and the GAP pattern, and measures the SSB.

[0276] In FIG. 12, the MGL of the GAP pattern is 6 ms, and the MGRP is 20 ms. As shown in FIG. 12, in the first MGL of the GAP pattern, since neither SSB transmission nor CSI-RS is activated, the Pre-MG does not need to be activated, and the unactivated Pre-MG will not be used for measurement.

[0277] In the second MGL of the GAP pattern, although the CSI-RS is not activated, there is SSB transmission, so the Pre-MG needs to be activated, and the SSB needs to be measured.

[0278] In the third MGL and the fourth MGL of the GAP pattern, the CSI-RS is activated, and there is also SSB transmission, so the terminal measures the SSB and the CSI-RS based on the Pre-MG.

[0279] As shown in FIG. 12, after the completion of the third CSI-RS transmission, the CSI-RS is deactivated, and there is also no SSB transmission. Therefore, the terminal can also deactivate the Pre-MG.

[0280] FIG. 13 is a schematic diagram five of reference signal measurement provided by the embodiment of the present disclosure, as shown in FIG. 13, for the CSI-RS of the aperiodic transmission in example three, the terminal measures the CSI-RS based on the Pre-MG and the GAP pattern, and measures the SSB.

[0281] In FIG. 13, the MGL of the GAP pattern is 6 ms, and the MGRP is 20 ms. As shown in FIG. 13, in the first MGL of the GAP pattern, since neither SSB transmission nor CSI-RS is activated, the Pre-MG does not need to be activated, and the unactivated Pre-MG will not be used for measurement.

[0282] In the second MGL of the GAP pattern, although the CSI-RS is not activated, there is SSB transmission, so the Pre-MG needs to be activated, and the SSB needs to be measured.

[0283] In the third MGL of the GAP pattern, after the network device informs the terminal through the DCI that the CSI-RS will be activated, since there is CSI-RS activation, and there is also SSB transmission, the terminal measures the SSB and the CSI-RS based on the Pre-MG.

[0284] In the fourth MGL of the GAP pattern, although the CSI-RS transmission ends, the transmission of the SSB exists, and therefore the terminal measures the SSB based on the Pre-MG. As shown in FIG. 13, after the SSB transmission is completed, the terminal can deactivate the Pre-MG.

[0285] It can be known in combination with Example Three that the flexibility of the reference signal measurement can be improved through the activation and deactivation of the Pre-MG.

[0286] Example Four: The transmission mode of the CSI-RS is the aperiodic transmission mode or the semi-persistent transmission mode, and the GAP pattern of the CSI-RS is a new measurement GAP pattern (that is, a GAP pattern different from the measurement GAP pattern in Example of Table 1).

[0287] The related parameter configuration cases in Example Four are shown in Table 6 as follows:

[0288] Table 6

[0289] It can be known based on Table 6 that the network device configures two GAPs and GAP patterns for the terminal, the first GAP has a GAP pattern 1 for measuring other types of reference signals (such as SSB), and the second GAP (Pre-MG) has a GAP pattern 2 (new measurement GAP pattern, that is, a measurement GAP pattern different from the measurement GAP pattern in Table 1) for measuring the CSI-RS.

[0290] The GAP pattern 1 (including MGL and MGRP) of the first GAP configured by the network device for the terminal adopts the measurement GAP pattern in Example of Table 1, and taking the first GAP MGL and MGRP as 6 ms and 20 ms respectively as an example. The MGL and MGRP in the GAP pattern 2 of the Pre-MG configured by the network device for the terminal are 6 ms and 32 ms respectively. In addition, the network device configures priorities for the two GAPs, and when collision of different measurements occurs, the terminal only needs to measure in the GAP pattern with high priority.

[0291] When the terminal measures, the new GAP pattern is used for the L1 measurement based on the CSI-RS, and the existing GAP pattern is used for other types of measurements by the terminal, which can be referred to Examples of FIG. 14-FIG. 15.

[0292] FIG. 14 is a schematic diagram of reference signal measurement six provided by the embodiment of the disclosure, as shown in FIG. 14, the terminal measures the SSB of the neighboring cell based on the GAP pattern 1, and for the semi-persistent CSI-RS in Example Four, the terminal measures the semi-persistent CSI-RS based on the Pre-MG and the GAP pattern 2.

[0293] The MGL=6 ms and the MGRP=20 ms of the GAP pattern 2 are illustrated in FIG. 14. As shown in FIG. 14, in the first MGL of the GAP pattern, since no CSI-RS is activated, the Pre-MG does not need to be activated, and the Pre-MG that is not activated is not used for measurement.

[0294] After the network device indicates the terminal to activate the CSI-RS through the second signaling, the terminal activates the Pre-MG, and therefore, in the second MGL of the GAP pattern 2, the terminal can perform measurement on the activated first CSI-RS, and in the third MGL of the GAP pattern 2, the terminal can perform measurement on the activated second CSI-RS. As shown in FIG. 14, after the transmission of the second CSI-RS is completed, the CSI-RS is deactivated, and therefore, the terminal can also deactivate the Pre-MG.

[0295] FIG. 15 is a schematic diagram of reference signal measurement provided by an embodiment of the present disclosure, as shown in FIG. 15, the terminal performs measurement on the SSB of the neighboring cell based on the GAP pattern 1, and performs measurement on the aperiodic CSI-RS based on the Pre-MG and the GAP pattern 2 for the aperiodic CSI-RS in example four.

[0296] As shown in FIG. 15, in the first MGL of the GAP pattern 2, since no CSI-RS is delivered, the Pre-MG does not need to be activated, and the Pre-MG that is not activated is not used for measurement.

[0297] After the network device informs the terminal through the DCI that the CSI-RS is about to be delivered, the terminal activates the Pre-MG, and therefore, in the second MGL of the GAP pattern 2, the terminal can perform measurement on the CSI-RS. After the transmission of the CSI-RS is completed, the terminal can deactivate the Pre-MG, and the deactivated Pre-MG is not used for measurement.

[0298] It can be known from example four that, by configuring multiple GAP patterns for the terminal, the measurement of reference signals with different transmission periods can be adapted, and the waste of GAP resources is reduced. Meanwhile, by activating and deactivating the Pre-MG, the flexibility of reference signal measurement is improved, and the terminal measurement efficiency and system throughput are improved.

[0299] Example five: the transmission mode of the CSI-RS is aperiodic transmission mode or semi-persistent transmission mode, and the GAP pattern of the CSI-RS is a new NCSG pattern (i.e., a GAP pattern different from the NCSG pattern in example of Table 2).

[0300] The related parameter configuration in example five is shown in Table 7.

[0301] Table 7

[0302] Based on Table 7, the network device configures two GAPs and GAP patterns for the terminal, the first GAP has GAP pattern 1 for measuring other types of reference signals (such as SSB), and the second GAP (Pre-MG) has GAP pattern 2 which is a new NCSG pattern (i.e. different from the NCSG pattern in Table 2) for measuring CSI-RS.

[0303] The first GAP pattern 1 (including MGL and MGRP) configured by the network device for the terminal uses the measurement GAP pattern in Table 1 as an example, and the MGL and MGRP of the first GAP are 3.5 ms and 20 ms respectively as an example. The ML and VIRP in the GAP pattern 2 of the Pre-MG configured by the network device for the terminal are 5 ms and 32 ms respectively. In addition, the network device will configure priorities for the two GAPs, and when collision of different measurements occurs, the terminal only needs to perform measurement in the GAP pattern with high priority.

[0304] When the terminal performs measurement, the new GAP pattern will be used for CSI-RS-based L1 measurement, and the existing GAP pattern will be used for other types of measurement, which can be seen from the examples of FIGS. 16-17.

[0305] FIG. 16 is a schematic diagram of reference signal measurement provided by an embodiment of the present disclosure. As shown in FIG. 16, the terminal measures the SSB of the neighboring cell based on the GAP pattern 1, and measures the semi-persistent transmission CSI-RS based on the Pre-MG and the GAP pattern 2 for the example of the semi-persistent transmission CSI-RS in Example Five.

[0306] In FIG. 16, the ML=5 ms and MGRP=32 ms of the GAP pattern 2 are shown. As shown in FIG. 16, in the first ML of the GAP pattern 2, since the CSI-RS is also not activated, the Pre-MG does not need to be activated, and the unactivated Pre-MG will not be used for measurement.

[0307] After the network device activates the CSI-RS by the second signaling, the terminal activates the Pre-MG, so in the second ML of the GAP pattern 2, the terminal can measure the first activated CSI-RS, and in the third ML of the GAP pattern 2, the terminal can measure the second activated CSI-RS. As shown in FIG. 16, after the transmission of the second CSI-RS is completed, the CSI-RS is deactivated, and therefore the terminal can also deactivate the Pre-MG.

[0308] FIG. 17 is a schematic diagram nine of reference signal measurement provided by the embodiments of the present disclosure, as shown in FIG. 17, the terminal measures the SSB of the neighboring cell based on the GAP pattern 1, and for the CSI-RS of the aperiodic transmission in example four, the terminal measures the CSI-RS of the aperiodic transmission based on the Pre-MG and the GAP pattern 2.

[0309] As shown in FIG. 17, in the first ML of the GAP pattern 2, since there is no CSI-RS to be delivered, the Pre-MG does not need to be activated, and the Pre-MG that is not activated will not be used for measurement.

[0310] After the network device informs the terminal that the CSI-RS will be delivered through the DCI, the terminal activates the Pre-MG, so in the second ML of the GAP pattern 2, the terminal can measure the CSI-RS. After the transmission of the CSI-RS is completed, the terminal can deactivate the Pre-MG, and the Pre-MG that is deactivated will not be used for measurement.

[0311] It can be known from example five that by configuring the terminal with multiple NCSG patterns, the measurement of reference signals with different transmission periods can be adapted, and the waste of GAP resources is reduced. At the same time, by activating and deactivating the Pre-MG, the flexibility of the reference signal measurement is improved, and the terminal measurement efficiency and system throughput are improved.

[0312] In summary, the scheme of the embodiments of the present disclosure provides a scheme for a terminal to support L1 measurement based on Pre-MG for a neighbor cell. The network device can configure one or more measurement GAPS for the terminal, so that the terminal can support L1 measurement based on a plurality of different types and configurations of reference signals. When the first reference signal is configured in a semi-persistent transmission mode or an aperiodic transmission mode, the terminal can activate the Pre-MG by activating the first time of the Pre-MG and the association between the transmission time information of the first reference signal in the time sequence, so that the terminal performs L1 measurement of the neighbor cell only in the activated MGL or ML, thereby improving the flexibility of network configuration, reducing the waste of GAP resources, and improving the throughput of the system. Further, the embodiments of the present disclosure also provide a new measurement GAP pattern and a new NCSG pattern, so that the scheme of the embodiments of the present disclosure can adapt to reference signal resources in a plurality of transmission modes and configuration modes. By introducing a new MGRP and VIRP, the problem of too long terminal measurement delay and resource waste caused by the fact that the configuration period of the reference signal is not a multiple of the measurement GAP period is solved, and the flexibility of network configuration and the system throughput are improved. The new MGL and ML are introduced, and the terminal is supported to complete the measurement of a plurality of frequency points in one MGL or ML, so that the problem that all frequency point measurements cannot be completed when a plurality of frequency point aperiodic or semi-persistent transmission reference signal sets are transmitted in one MGL or ML is solved, and the terminal measurement efficiency and the system throughput are improved.

[0313] FIG. 18 is a structural schematic diagram of a reference signal measurement device provided by the embodiments of the present disclosure. As shown in FIG. 18, the device includes a memory 1820, a transceiver 1800, and a processor 1810.

[0336] The third time is earlier than the second start time, and a length of time between the third time and the second start time is greater than or equal to a length of time required for RF link switching of the terminal.

[0337] In some embodiments, the GAP pattern of the Pre-MG is a first measurement GAP pattern, and the first measurement GAP pattern is used to indicate a measurement gap length of the Pre-MG and a measurement gap repetition period of the Pre-MG.

[0338] or

[0339] The GAP pattern of the Pre-MG is a first NCSG pattern, and the first NCSG pattern is used to indicate a measurement length of the Pre-MG and a visible break repetition period of the Pre-MG.
