[0039] To facilitate understanding, the concepts involved in this application are first explained.

[0040] 3GPP: 3rd Generation Partnership, third generation partnership project.

[0041] Terminal device: It can be a device that includes wireless transceiver functions and can cooperate with network devices to provide communication services to users. Specifically, terminal device can refer to user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. For example, the terminal device can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network or a network after 5G, etc.

[0042] Network equipment: A network equipment may be a device used to communicate with a terminal device, for example, it may be a base station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) communication system, a base station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) system, or an evolved base station (eNB or eNodeB) in an LTE system, or the network equipment may be a relay station, an access point, an in-vehicle device, a wearable device, a network-side device in a future 5G network or a network after 5G, or a network device in a future evolved Public Land Mobile Network (PLMN) network, etc.

[0043] The network devices involved in the embodiments of the present application may also be referred to as radio access network (RAN) devices. The RAN device is connected to the terminal device, and is used to receive data from the terminal device and send it to the core network device. The RAN device corresponds to different devices in different communication systems. For example, in the second-generation mobile communication (2th-Generation, 2G) system, it corresponds to the base station and the base station controller, in the third-generation mobile communication (3rd-Generation, 3G) system, it corresponds to the base station and the radio network controller (Radio Network Controller, RNC), in the fourth-generation mobile communication (4th-Generation, referred to as 4G) system, it corresponds to the evolved base station (Evolutional Node B, eNB), and in the 5G system, it corresponds to the 5G system, such as the access network equipment in NR (for example, the next generation Node B (gNB), the centralized unit (CU), and the distributed unit (DU)).

[0044] Mobility measurement: Mobility measurement is an important part of wireless communication networks. Terminal devices can obtain the signal quality of their own cell and neighboring cells by performing mobility measurements and report the relevant measurement results to network equipment. The network equipment determines whether the terminal device should perform cell switching based on the measurement results reported by the terminal device. Among them, mobility measurement can better support the mobility of terminal devices, perform switching and cell reselection in a timely manner, and ensure the reliability and continuity of user services.

[0045] Frequency: Refers to a specific absolute frequency value, generally the center frequency of the modulating signal. Frequency is a number given to a fixed frequency.

[0046] Intra-frequency measurement: The frequency of the target cell to be measured is the same as the frequency of the current serving cell.

[0047] Inter-frequency measurement: The frequency of the target cell to be measured is different from the frequency of the current serving cell.

[0048] Inter-RAT measurement: The network standard of the target cell to be measured is different from the network standard of the current serving cell.

[0049] In addition, it should be understood that in the description of this application, words such as "first" and "second" are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying the order, nor can they be understood as indicating or implying the relationship between similar nouns.

[0051] Figure 1 This is a schematic diagram of a communication scenario provided by an embodiment of this application. Figure 1 , including a network device 101 and a terminal device 102, and wireless communication can be performed between the network device 101 and the terminal device 102, wherein the terminal device 102 can communicate with at least one core network via a radio access network (Radio Access Network, RAN).

[0052] The communication system may be a Global System of Mobilecommunication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a Long Term Evolution (LTE) system or a fifth-generation mobile communication (5G) system.

[0053] Correspondingly, the base station can be a base station (Base Transceiver Station, BTS) in a GSM system or a CDMA system, a base station (NodeB, NB) in a WCDMA system, an evolved NodeB (eNB), an access point (AP) or a relay station in an LTE system, or a base station in a 5G system, etc., without limitation here.

[0054] The 5G mobile communication system described in this application includes a non-standalone (NSA) 5G mobile communication system and / or a standalone (SA) 5G mobile communication system. The technical solution provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system. The communication system can also be a PLMN network, a device-to-device (D2D) network, a machine-to-machine (M2M) network, an IoT network, or other networks.

[0055] It is understandable that if the technical solutions of the embodiments of the present application are applied to other wireless communication networks, the corresponding names can also be replaced by the names of corresponding functions in other wireless communication networks.

[0056] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems.

[0057] Based on the above introduction, the following Figure 2 A detailed introduction to mobility measurement is given. Figure 2 Schematic diagram of mobility measurement provided in an embodiment of the present application:

[0058] like Figure 2 As shown, the current system includes a terminal device 110 and multiple network devices 120-124, wherein it is assumed that the terminal device is currently connected to the network device 120 (for example, in radio resource control (RRC) connection mode) and operates in a service cell 130 provided by the network device 120, and the terminal device 110 can also be within the coverage area of ​​a group of adjacent cells 131-134 provided by the network devices 121-124 respectively.

[0059] In various embodiments, the network devices 120-124 may implement the same or different radio access technologies, such as NR air interface, Evolved Universal Terrestrial Radio Access (E-UTRA) air interface, Universal Terrestrial Radio Access Network (UTRAN) air interface, Global System for Mobile Communication (GSM) Enhanced Data Rate for GSM Evolution (EDGE) Radio Access Network (GERAN) air interface, and the like.

[0060] Among them, each of the network devices 120-124 can implement the functions of the next generation NodeB (gNB), evolved NodeB (eNodeB), NodeB, etc. specified by the corresponding standards developed or maintained by the 3rd Generation Partnership Project (3GPP).

[0061] Therefore, in one embodiment, the terminal device 110 may be a device that communicates with the network devices 120 - 124 according to corresponding communication protocols corresponding to the wireless access technologies used by the corresponding network devices.

[0062] In one possible implementation, the terminal device may receive a set of measurement configurations from the serving cell 130 , and the terminal device 110 performs a measurement process to measure the serving cell 130 and the neighboring cells 121 - 124 , and sends a measurement report to the network device 120 .

[0063] For example, the network device 120 may send the measurement configuration to the terminal device 110 via RRC signaling. For example, the measurement may be performed based on reference signals (RS) sent by the network devices 121-124, or may also be performed based on a reference signal sent by the network device 120.

[0064] In one possible implementation, the reference signal may be a synchronization signal block SSB or CSI-RS, etc., where the synchronization signal block is also called a synchronization signal / physical broadcast channel (PBCH), which may include one or more of PBCH, primary synchronization signal (PSS) and secondary synchronization signal (SSS).

[0065] In this embodiment, the measurement configuration 141 may specify a set of measurement objects (MO). In one possible implementation, the measurement objects may be in units of frequency points, and each configured measurement object is a separate frequency point with a separate measurement object identifier. For example, for E-UTRA intra-frequency measurement and inter-frequency measurement, the measurement object may be a separate E-UTRA carrier frequency.

[0066] Among them, the type of MO can be, for example, CSI-RS measurement, then the CSI-RS measurement can be configured in the MO, for example, a series of measurement-related parameters are configured in the MO, or the measurement object can also be the type of SSB measurement, then the SSB measurement can be configured in the MO, for example, a series of measurement-related parameters are configured in the MO.

[0067] The measurement configuration 141 may also specify a set of qualities to be measured corresponding to the MO. For example, the measured qualities include reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-noise and interference ratio (SINR), reference signal time difference (RSTD), etc.

[0068] The following combination Figure 2 Taking the reference signal SSB as an example, the same-frequency measurement, different-frequency measurement and different-standard measurement are explained. In a possible implementation method, according to the 3GPP NR standard, in the NR system, if the center frequency of the SSB of the serving cell indicated for measurement is the same as the center frequency of the SSB of the target cell, and the subcarrier spacing of the two SSBs is also the same, the measurement can be defined as a same-frequency measurement based on SSB. For example, the measurement of the adjacent cell 131 can be determined as a same-frequency measurement.

[0069] On the contrary, if the center frequency of the SSB of the serving cell indicated for measurement is different from the center frequency of the SSB of the target cell, the measurement can be defined as an inter-frequency measurement based on SSB. For example, the measurement of the neighboring cell 133 can be determined as an inter-frequency measurement.

[0070] In addition, see Figure 2 When the neighboring cell 134 implements a RAT different from that of the serving cell 130 , the measurement performed on the neighboring cell 134 may be determined as a heterogeneous measurement.

[0071] Those skilled in the art will understand that, under normal circumstances, a terminal device has only one receiver, and therefore can only receive signals at one frequency at the same time. In order to ensure that the terminal device can perform mobility measurement, a measurement GAP can be configured for the terminal device, where the measurement GAP is the time period for the terminal device to leave the current frequency and measure at other frequencies.

[0072] During the GAP measurement, the terminal device can tune its radio frequency (RF) circuit from the frequency of the serving cell to the frequency of the target cell to perform cell search or measurement, and stop normal uplink and downlink data transmission on the serving cell in the corresponding frequency domain until the GAP measurement is completed.

[0073] In the NR system, the operating frequency range of terminal devices not only extends below 6 GHz but also includes millimeter wave frequency bands above 6 GHz. Therefore, RAN4 defines per-UE and per-FR measurement gaps, namely gapFR1, gapFR2, and gapUE, based on whether the terminal device supports the FR1 / FR2 frequency range. Correspondingly, the terminal device also introduces an independent measurement gap configuration (independentGapConfig), which is used to indicate whether the terminal device can configure the perFR1 / 2 measurement gap.

[0074] gapFR1: This measurement gap configuration applies only to FR1. GapFR1 and gapUE cannot be configured simultaneously. In addition, in EN-DC mode, gapFR1 does not support NR RRC configuration; only LTE RRC can configure FR1 gap.

[0075] gapFR2: This measurement interval configuration applies only to FR2. gapFR2 and gapUE cannot be configured simultaneously.

[0076] gapUE: This measurement gap configuration applies to all frequency bands, including FR1 and FR2. In EN-DC mode, only LTERRC can be configured with gapUE; NR RRC configuration is not supported. If gapUE is configured, gapFR1 or gapFR2 cannot be configured.

[0077] For a per-UE gap, the terminal device is not allowed to send any data and is not expected to adjust the receiver of the primary and secondary carriers. If the terminal device supports the independent gap capability, that is, the FR1 and FR2 measurements can be independent and unaffected, then the terminal device can configure a per-FR measurement gap.

[0078] In the embodiment of the present application, the parameter configuration of the measurement gap includes measurement gap length (MGL), measurement gap repetition period (MGRP), measurement gap offset (measurement gap offset), and measurement gap timing advance (MGTA).

[0079] MGL can be 1.5ms, 3ms, 3.5ms, 4ms, 5.5ms, or 6ms. MGRP can be 20ms, 40ms, 80ms, or 160ms. MGTA can be 0ms, 0.25ms (FR2), or 0.5ms (FR1). MG offset can be any value in the set {0, 1, ..., MGRP-1}, where the unit of the value in the set {} is milliseconds.

[0080] In one possible implementation, the terminal device may determine the starting position of the measurement interval according to the following formula:

[0081] SFN mod T=FLOOR(gapOffset / 10);

[0082] subframe=gapOffset mod 10;

[0083] with T=MGRP / 10.

[0084] Wherein, SFN represents the system frame number, FLOOR represents rounding down, mod represents the modulo function, and subframe represents the subframe number.

[0085] Currently, the protocol supports 24 measurement gap patterns, see Table 1.

[0086] Table 1

[0087]

[0088]

[0089] The MO in the measurement configuration includes the same-frequency MO, different-frequency MO, or different-network MO. The measurement configuration can specify a set of parameters to be measured corresponding to the MO. For example, the parameters to be measured include reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-noise and interference ratio (SINR), reference signal time difference (RSTD), etc.

[0090] In the NR system, network equipment can configure SMTC for terminal devices. SMTC is used to instruct the terminal device to measure SSB information. SMTC includes one or more of the SMTC period, SMTC duration (also known as window length), and SMTC time offset.

[0091] The SMTC period can be 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms. The SMTC length, also known as the SMTC duration, can be 1ms, 2ms, 3ms, 4ms, or 5ms. The SMTC time offset can be any value in the set {0, 1, ..., SMTC period - 1}, where the unit of the value in the set {} is milliseconds (ms).

[0092] In one possible implementation, the terminal device may determine the starting position of the SMTC according to the following formula:

[0093] SFN mod T=(FLOOR(Offset / 10));

[0094] If the period of SMTC is greater than sf5: subframe = Offset mod 10,

[0095] Otherwise subframe=Offset or(Offset+5);

[0096] with T=CEIL(Periodicity / 10).

[0097] Wherein, SFN represents the system frame number, FLOOR represents rounding down, subframe represents the subframe number, CEIL represents the rounding function, and Periodicity represents the period of SMTC.

[0098] One or more SMTCs can be configured for an MO. In one possible implementation, for intra-frequency measurements in a connected state, a same-frequency MO can be configured with two SMTCs (SMTC1 and SMTC2). These two SMTCs can have the same time offset and different periods (for example, the period of SMTC2 is smaller than the period of SMTC1); for inter-frequency measurements, only one SMTC (SMTC1) is configured.

[0099] The period of SMTC2 is shorter than that of SMTC1. The timing offset of SMTC2 follows that of SMTC1 and is equal to periodicityAndOffset mod periodicity. SMTC2 currently supports only co-frequency measurement configuration.

[0100] The following combination Figure 3 An example of how to configure two SMTCs is given below. Figure 3 A schematic diagram of the configuration of two SMTCs of the measurement interval and the measurement object provided in an embodiment of the present application.

[0101] As an example, Figure 3 As shown in the figure, assume that the network device configures two SMTCs for the same MO, namely SMTC1 and SMTC2, with the same SMTC offset and length (e.g. 5ms), SMTC1 period is 20ms, and SMTC2 period is 10ms. The network configures the MG period to be 20ms and the MG length to be 6ms.

[0102] Combined with the above Figure 3 It is certain that the SMTC partially overlaps with the measurement interval, that is, Figure 3 The measurement interval in can only cover part of SMTC2 of the MO.

[0103] In other possible implementations, it is also possible that all SMTCs are within the measurement interval, or that all SMTCs are outside the measurement interval. Figure 4 and Figure 5 Explain them separately. Figure 4 This is a schematic diagram of the implementation of SMTC within the measurement interval provided in the embodiment of the present application. Figure 5 This is a schematic diagram of the implementation of SMTC provided in an embodiment of the present application that is entirely outside the measurement interval.

[0104] See also Figure 4, assuming that the network device configures two SMTCs for the same-frequency MO, namely SMTC1 and SMTC2, with the same SMTC offset and length (for example, 5ms), the period of SMTC1 is 20ms, the period of SMTC2 is 10ms, and only one SMTC is configured for the different-frequency MO. For the specific configuration, see Figure 4 Assume that the network configures the MG period to be 20ms and the MG length to be 6ms.

[0105] Combined with the above Figure 4 It is certain that the current SMTC is all within the measurement interval, that is, Figure 4 The measurement interval in can cover all SMTCs.

[0106] See also Figure 5 , assuming that the network device configures two SMTCs for the same-frequency MO, namely SMTC1 and SMTC2, with the same SMTC offset and length (for example, 5ms), the period of SMTC1 is 20ms, the period of SMTC2 is 10ms, and only one SMTC is configured for the different-frequency MO. For the specific configuration, see Figure 5 Assume that the network configures the MG period to be 20ms and the MG length to be 6ms.

[0107] Combined with the above Figure 5 It is certain that the current SMTC is all outside the measurement interval, that is, Figure 5 The measurement interval in does not cover any SMTC.

[0108] Based on the relevant content of SMTC introduced above, it can be determined that in order to limit the configuration used to measure SSB from the time domain, the SSB measurement time configuration window SMTC is defined. In the process of mobility measurement, in addition to SSB, the reference signal also includes CSI-RS. However, there is currently no time domain position constraint for CSI-RS measurement. Since the CSI-RS resource itself is more flexible, including periodic and non-periodic, if the measurement time domain of CSI-RS is not constrained, the implementation of mobility measurement will be complicated, thereby reducing the efficiency of mobility measurement.

[0109] In response to the problems in the prior art, the present application provides a measurement method to implement time domain constraints on CSI-RS measurements, thereby effectively reducing the implementation complexity of mobility measurements and improving the efficiency of mobility measurements.

[0110] The following describes the measurement method provided by this application in conjunction with specific embodiments. Figure 6 Make an introduction, Figure 6 This is a flow chart of a measurement method provided in one embodiment of the present application.

[0111] like Figure 6 As shown, the method includes:

[0112] S601. Acquire first time domain information, where the first time domain information is used to indicate a time domain for measuring a channel state information reference signal CSI-RS.

[0113] In this embodiment, the terminal device can perform mobility measurement based on CSI-RS, and the first time domain information in this embodiment is used to indicate the time domain position of CSI-RS, so the terminal device can quickly determine at which time domain positions to measure CSI-RS based on the first time domain information.

[0114] In one possible implementation, the first time domain information can be used to indicate at least one of the following information: measurement period, measurement length, and measurement starting position. It can be understood that the period of the time domain range can be determined according to the measurement period, the length of the time domain range can be determined according to the measurement length, and the position from which to start the measurement can be determined according to the measurement starting position. Therefore, the periodic time domain range can be accurately determined based on the above information. Therefore, by obtaining the first time domain information, it can be determined on which time domain ranges to measure the CSI-RS.

[0115] In one possible implementation, for example, the first time domain information can be obtained by receiving time domain related information sent from a network device; or, the first time domain information can be agreed upon with the network device in advance, and the first time domain information can be obtained locally from the terminal device when needed; or, the first time domain information can be predefined by a protocol to obtain the first time domain information. This embodiment does not limit the specific implementation method for obtaining the first time domain information. It can be any of the above implementation methods, or it can also be any scalable implementation method, as long as the first time domain information indicating the time domain position of the measurement object can be obtained.

[0116] S602: Perform mobility measurement according to the first time domain information.

[0117] Among them, according to the first time domain information, it can be determined in which time domain ranges the CSI-RS is measured, and the terminal device can measure the CSI-RS within the time domain range indicated by the first time domain information. The specific implementation method of the mobility measurement has been introduced in the above embodiment and will not be repeated here.

[0118] The measurement method provided in an embodiment of the present application includes: obtaining first time domain information, wherein the first time domain information is used to indicate a time domain for measuring a channel state information reference signal (CSI-RS). Performing mobility measurement based on the first time domain information. By obtaining the first time domain information indicating a time domain position for measuring the CSI-RS, mobility measurement can be performed on the CSI-RS at the time domain position indicated by the first time domain information, thereby constraining the measurement time domain of the CSI-RS, thereby reducing the implementation complexity of the mobility measurement and improving the efficiency of the mobility measurement.

[0119] Based on the above embodiments, various possible implementations of the first time domain information are described below.

[0120] In one possible implementation, a set of measurement time window configurations dedicated to CSI-RS measurement may be newly introduced, and the first time domain information may include the newly introduced at least one measurement time configuration information. A possible implementation of obtaining the first time domain information may be:

[0121] At least one measurement time configuration information sent from a network device is received.

[0122] The measurement time configuration information sent by the network device may be defined as, for example, channel state information reference signal measurement timing configuration information (CSI-RS measurement timing configuration, CMTC), or it may be other names. As long as the measurement time configuration information is used to indicate the time domain position for measuring the CSI-RS, other possible implementation names may be used as the measurement time configuration information in this embodiment.

[0123] For ease of description, the measurement time configuration information is CMTC as an example for introduction below. The implementation methods of other possible names are similar.

[0124] Based on the above introduction, it can be determined that the first time domain information in this embodiment is used to indicate at least one of the measurement period, measurement length, and measurement starting position. In a possible implementation of this embodiment, the measurement time configuration information includes at least one of the following information: the first measurement period, the first measurement length, and the first measurement starting position.

[0125] Furthermore, the measurement time configuration information in this embodiment may further include a first measurement offset (Offset). In a possible implementation, the first measurement start position may be determined according to the first measurement period and the first measurement offset.

[0126] The terminal device may determine the first measurement starting position of the CMTC according to the following formula, for example:

[0127] SFN mod T=(FLOOR(Offset / 10));

[0128] If the CMTC period is greater than sf5: subframe = Offset mod 10,

[0129] Otherwise subframe=Offset or(Offset+5);

[0130] with T=CEIL(Periodicity / 10).

[0131] SFN represents the system frame number, FLOOR represents rounding down, subframe represents the subframe number, CEIL represents the rounding function, Periodicity represents the first measurement period, and Offset represents the first measurement offset.

[0132] In a possible implementation, the first measurement period is any one of the first period set;

[0133] Among them, the first period set is the set {5×2 0 , 5×2 1 , 5×2 2 , 5×2 3 ,…,5×2 Z} a subset of milliseconds, where Z is an integer greater than or equal to 0.

[0134] In a possible implementation, the first measured length is any one of a first length set;

[0135] The first length set is a subset of the set {1, 2, 3, 4, 5, ..., 10} milliseconds.

[0136] In a possible implementation, the first measurement offset is a positive integer less than or equal to the first measurement period.

[0137] The following is an explanation with specific examples:

[0138] For example, the first measurement period may be any one of the set {5, 10, 20, 40}, or the first measurement period may be any one of the set {10, 20, 40};

[0139] For example, the first measurement length may be any one of the set {1, 2, 3, 4, 5};

[0140] For example, the first measurement bias may be any one of the set {10, 20, 40}.

[0141] The unit of the values ​​in each set {} introduced above is milliseconds (ms).

[0142] In an actual implementation process, various possible implementations of the first measurement period, the first measurement length, and the first measurement offset may be selected according to actual needs.

[0143] In this embodiment, at least one measurement time configuration information sent from a network device may be received, and thus at least one CMTC may be set for the MO:

[0144] In one possible implementation method, the number of SMTCs for the current same-frequency MO and different-frequency MO can be set with reference to the same-frequency MO. Two measurement time configuration information out of at least one measurement time configuration information can be configured for the same-frequency MO, and one measurement time configuration information out of at least one measurement time configuration information can be configured for the different-frequency MO.

[0145] Alternatively, in another possible implementation method, one measurement time configuration information out of at least one measurement time configuration information can be configured for the same-frequency MO, and one measurement time configuration information out of at least one measurement time configuration information can be configured for the different-frequency MO. This setting can effectively reduce the difficulty of implementation.

[0146] Alternatively, in another possible implementation, X measurement time configuration information in at least one measurement time configuration information may be set for the same-frequency MO, and Y measurement time configuration information in at least one measurement time configuration information may be configured for the inter-frequency MO, where X is an integer greater than or equal to 2, and Y is an integer greater than or equal to 2. The specific configuration numbers of X and Y may depend on the capabilities of the terminal device.

[0147] In this embodiment, CSI-RS measurement can be configured in the MO. For an MO configured with multiple CMTCs, the terminal device can select one of the multiple CMTCs, thereby performing mobility measurement according to the selected CMTC. The following describes possible implementation methods for selecting the CMTC:

[0148] Specifically, if the MO is configured with at least two measurement time configuration information, the second measurement time configuration information among the at least two measurement time configuration information is selected, wherein the second measurement time configuration information is used to perform mobility measurement.

[0149] In a possible implementation, the second measurement time configuration information is the one with the smallest first measurement period among the at least two measurement time configuration information.

[0150] That is, the selection is prioritized according to the period, and the time configuration information with the smallest first measurement period is selected for mobility measurement. In this possible implementation, at least two measurement time configuration information may have the same length, or there may be no limit on the length of the measurement time configuration information. In either case, the one with the smallest first measurement period is preferably selected.

[0151] In another possible implementation, if the first measurement periods of at least two pieces of measurement time configuration information are the same, the second measurement time configuration information is the one with the shortest first measurement length among the at least two pieces of measurement time configuration information.

[0152] The selection is preferably made according to the period. When the first measurement periods are the same, the selection is made according to the first measurement lengths, and the one with the shortest first measurement length is selected as the second measurement time configuration information.

[0153] In another possible implementation manner, the second measurement time configuration information may be determined by the terminal device.

[0154] Any one of the plurality of CMTCs may be determined based on the selection of the terminal device.

[0155] In this embodiment, the basic unit of measurement time may be CMTC and / or MGRP itself.

[0156] Based on the above introduction, the following takes the measurement time configuration information as CMTC as an example, combined with Figure 7 A possible implementation of the measurement time configuration information is described. Figure 7 A schematic diagram of a possible configuration of the measurement time configuration information provided in an embodiment of the present application.

[0157] As an example, Figure 7 As shown, it is assumed that the network device configures two CMTCs for the same MO, namely CMTC1 and CMTC2, with the same CMTC offset and length (for example, 5ms), CMTC1's period is 20ms, and CMTC2's period is 10ms. It is also assumed that the network configures the MG's period to be 20ms and the MG's length to be 6ms.

[0158] Combined with the above Figure 7 It is certain that the CMTC partially overlaps with the measurement interval, that is, Figure 7 The measurement interval in can only cover part of the CMTC2 of the MO.

[0159] Alternatively, in other possible implementations, it is also possible that all CMTCs are within the measurement interval, or that all CMTCs are outside the measurement interval. The implementation method is similar to the implementation method of the SMTC described above, and can refer to the above-described Figure 7 The implementation method of SMTC is the same as that described above and will not be repeated here.

[0160] In the embodiments of this application, a new set of measurement time window configurations dedicated to CSI-RS measurements is introduced, thereby retaining the time domain configuration restrictions of SSB measurements. This implements the CSI-RS resource configuration restrictions and avoids the increased complexity of terminal device implementation due to excessive configuration types and excessive time domain flexibility. At the same time, the SMTC framework is referenced to introduce new measurement time configuration information, thereby ensuring good compatibility with the signaling structure and MG configuration of existing measurement configurations, with minimal changes.

[0161] Based on the above embodiment, in another possible implementation, CMTC may not be introduced, but SMTC may be reused during CSI-RS measurement. This implementation is described below:

[0162] If the CSI-RS measurement and SSB measurement are configured in the same MO, the first time domain information is obtained, including:

[0163] Acquire the SMTC of the MO, wherein the first time domain information includes at least one of the following information: a second measurement period of the SMTC, a second measurement length of the SMTC, and a second measurement start position of the SMTC.

[0164] In one possible implementation, the first time domain information may also include a second measurement offset of the SMTC, wherein the second measurement start position is determined based on the second measurement period and the second measurement offset. The determination method is the same as the implementation method of determining the measurement start position of the SMTC described above, and will not be repeated here.

[0165] Specifically, when CSI-RS measurement and SSB measurement are configured in the same MO, for the measurement of this MO, the reference signal follows the constraints and configuration of SMTC in the time domain, that is, the terminal device is required to perform measurement only for CSI-RS or SSB within the SMTC window.

[0166] The CSI-RS measurement reuses the existing SMTC configuration, and the definition requirements of the gap configuration and measurement time in this embodiment also follow the current SMTC and Gap existing solutions. At the same time, the basic unit of measurement time is SMTC and / or MGRP itself.

[0167] The above description describes the case where MO includes both CSI-RS measurement and SSB measurement. However, when MO only includes CSI-RS measurement, the terminal device cannot refer to SMTC. In this case, CSI-RS can be measured based on its own period and length.

[0168] In a possible implementation manner, the terminal device may receive first indication information sent from the network device, where the first indication information is used to indicate a third measurement starting position.

[0169] And the terminal device can obtain the period of CSI-RS and the length of CSI-RS, wherein the first time domain information includes at least one of the following information: the period of CSI-RS, the length of CSI-RS, and the third measurement starting position.

[0170] Specifically, when the network device sends CSI-RS, the CSI-RS itself has its own period and length, so the terminal device can also determine the period of the CSI-RS and the length of the CSI-RS. Therefore, the first time domain information in this embodiment can include the period of the CSI-RS and the length of the CSI-RS.

[0171] The terminal device in this embodiment can also obtain the first indication information sent by the network device, thereby obtaining the third measurement starting position. Therefore, the measurement period in this embodiment is the CSI-RS period, the measurement length is the length of the CSI-RS, and the measurement starting position is the third measurement starting position.

[0172] And in this embodiment, the basic unit of measurement time is the CSI-RS period itself.

[0173] The following combination Figure 8 Describe the current implementation. Figure 8 A schematic diagram of a measurement window determined based on CSI-RS provided in an embodiment of the present application.

[0174] As an example, Figure 8 As shown, assuming that the current CSI-RS period is 10ms and the CSI-RS length is 5ms, then see Figure 8 , at this time, the first time domain information includes the period of CSI-RS, the length of CSI-RS, and the third measurement starting position, then the period of MO's measurement window is 10ms, and the length of the measurement window is 5ms. For the implementation method, see Figure 8 .

[0175] Figure 8The description is about the case where all measurement windows are within the measurement interval. In other possible implementations, there may also be partial overlap or all measurement windows are outside the measurement interval. The implementation method is similar to the above description and will not be repeated here.

[0176] The above introduction directly performs CSI-RS mobility measurement based on the CSI-RS period and the CSI-RS length, without limiting the measurement period and length. In other possible implementations, the first indication information sent by the network device may further limit the period and / or length of the CSI-RS measurement based on the CSI-RS period and the CSI-RS length.

[0177] In a possible implementation manner, the first indication information is further used to indicate that the length of the measurement window for measuring the CSI-RS does not exceed a first length threshold.

[0178] For example, it is indicated that the length of the measurement window for measuring the CSI-RS does not exceed 5 ms, while there is no restriction on the period for measuring the CSI-RS.

[0179] In another possible implementation manner, the first indication information is further used to indicate that a measurement period for measuring the CSI-RS is not greater than a first period threshold.

[0180] For example, it is indicated that the period of measuring CSI-RS is not greater than 40 ms, while there is no restriction on the length of the measurement window for measuring CSI-RS.

[0181] In another possible implementation, the first indication information is further used to indicate that the length of the measurement window for measuring the CSI-RS does not exceed a first length threshold, and the first indication information is further used to indicate that the measurement period for measuring the CSI-RS is not greater than a first period threshold.

[0182] For example, it indicates that the period of measuring CSI-RS is not greater than 40 ms, and it indicates that the length of the measurement window of measuring CSI-RS is not greater than 5 ms.

[0183] Which of the above implementations is specifically adopted can be determined according to the first indication information of the network device, and the first length threshold and the first period threshold introduced above are also indicated by the network device.

[0184] In this embodiment, the network device may directly or indirectly indicate the third measurement starting position. The above description is an implementation method of directly indicating the third measurement starting position through the first indication information. In another possible implementation method, the third measurement starting position may also be obtained indirectly by decoding a reference sequence sent by the network device.

[0185] In this embodiment, by reusing the SMTC of the existing SSB measurement configuration, the problem of CSI-RS measurement time domain configuration constraint is solved, so as to reduce the problem of overly flexible CSI-RS resource configuration, reduce the implementation complexity of mobility measurement, and improve measurement efficiency.

[0186] Based on the above embodiments, the present application can also use the CSI-RS period and CSI-RS length for mobility measurement through protocol pre-configuration, and impose certain restrictions or constraints on the CSI-RS period and length to determine the time domain position and starting position of the CSI-RS.

[0187] The first time domain information is configured by the protocol, and the first time domain information includes the period of the CSI-RS, the length of the CSI-RS, and the fourth measurement starting position.

[0188] Its implementation is similar to the implementation of the first indication information described in the above embodiment, except that the first time domain information in this embodiment is pre-configured by the protocol and does not require indication by the network device.

[0189] In a possible implementation, the first time domain information further includes that the length of the measurement window for measuring the CSI-RS does not exceed a second length threshold.

[0190] For example, the length of the measurement window for measuring the CSI-RS does not exceed 5 ms, and there is no restriction on the period for measuring the CSI-RS.

[0191] In another possible implementation, the first time domain information further includes that a measurement period for measuring the CSI-RS is not greater than a second period threshold.

[0192] For example, the period for measuring the CSI-RS is no more than 40 ms, and there is no restriction on the length of the measurement window for measuring the CSI-RS.

[0193] In another possible implementation, the first time domain information further includes that the length of the measurement window for measuring the CSI-RS does not exceed the second length threshold, and the first time domain information further includes that the measurement period for measuring the CSI-RS is not greater than the second period threshold.

[0194] For example, it indicates that the period of measuring CSI-RS is not greater than 40 ms, and it indicates that the length of the measurement window of measuring CSI-RS is not greater than 5 ms.

[0195] In this embodiment, the fourth measurement starting position may be directly indicated by the network device through the second indication information; or

[0196] The fourth measurement starting position is indirectly indicated by the network device through a reference sequence.

[0197] In this embodiment, the basic unit of measurement time may be the CSI-RS period itself.

[0198] In this embodiment, constraints are imposed on the CSI-RS measurement time domain configuration to reduce the problem of overly flexible CSI-RS resource configuration, thereby improving measurement efficiency. Furthermore, by means of protocol pre-configuration, no additional signaling configuration and overhead are introduced.

[0199] On the basis of the above embodiment, in the measurement method provided by the present application, the network device can also obtain the first time domain information and send the CSI-RS according to the first time domain information. Figure 9 This section introduces the measurement methods on the network device side.

[0200] Figure 9 This is a flow chart of a measurement method provided in another embodiment of the present application.

[0201] like Figure 9 As shown, the method includes:

[0202] S901. Acquire first time domain information, where the first time domain information is used to indicate a time domain position for measuring a channel state information reference signal CSI-RS.

[0203] In this embodiment, the implementation method of the network device obtaining the first time domain information is similar to the above-mentioned description. For example, it can be the measurement time configuration information determined by the network device; or it can be the time domain information of the multiplexed SMTC; or it can be the information configured by the protocol. The specific implementation method can refer to the description in the above-mentioned embodiment.

[0204] S902: Send CSI-RS according to the first time domain information.

[0205] The network device sends the CSI-RS according to the first time domain information, so that the terminal device can measure the CSI-RS within the time domain range indicated by the first time domain information, thereby effectively reducing the complexity of mobility measurement and improving measurement efficiency.

[0206] The remaining implementation methods are similar to those on the terminal device side described above and will not be repeated here.
