[0013] In some embodiments, after executing the layer three-part correlation process, performing a layer one reference signal received power measurement according to the reduced receive beam scanning coefficient includes: when the layer one reference signal received power measurement is a reference signal received power measurement based on the channel state information reference signal CSI-RS, and when the synchronization signal and physical broadcast channel block SSB in the layer three-part correlation process have a quasi-co-location type D relationship with the channel state information reference signal CSI-RS, after executing the layer three-part correlation process, performing a layer one reference signal received power measurement according to the reduced receive beam scanning coefficient.

[0027] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0028] This disclosure proposes a measurement method, as follows Figures 1-2 Give a description.

[0029] Figure 1 Flow charts of some embodiments of the measurement method disclosed herein. Figure 1 As shown, the method of this embodiment is executed by a terminal and includes steps S102 to S104.

[0030] In step S102, during the secondary cell activation process, layer 3 related processes are executed.

[0031] Layer 3 is the RRC (Radio Resource Control) layer. During the activation of the secondary cell (SCell), the L3 Part Related Procedure can be executed first. For example, the secondary cell activation process includes: automatic gain control (AGC) adjustment, cell search and time-frequency tracking and beam information acquisition, layer 1 reference signal received power measurement (L1-RSRP Measurement), layer 1 reference signal received power report, transmission configuration indication activation, fine time tracking, etc. Automatic gain control adjustment, cell search and time-frequency tracking and beam information acquisition belong to the layer 3 part related procedures, and other procedures are layer 1 part related procedures.

[0032] The standard defines the activation delay of an unknown secondary cell as: 6ms+T FirstSSB_MAX +15*T SMTC_MAX +8*T rs +T L1-RSRP,measure +T L1-RSRP,report +T HARQ +max(T uncertainty_MAC +T FineTiming +2ms,T uncertainty_SP ), when the primary and secondary cells are configured as FR1-FR2-1 CA or the primary and secondary cells are FR2-1 band pairs with independent beam management, and semi-persistent CSI-RS is configured for CSI reporting

[0033] Among them, T FirstSSB_MAX It is indicated by SMTC (SSB (Synchronization Signal / PBCH Block, Synchronization Signal / Physical Broadcast Channel Block) Measurement Timing Configuration) in time slot n+(T HARQ +3ms) / time slot length and continues until the end of the first complete SSB burst, or 5ms when SMTC is not configured. SMTC_MAX It is the longer SMTC period between the activated secondary cell and the activated serving cell. rs is the SMTC period of the activated SCell or T rs Set to 5ms. L1-RSRP，measure is the L1-RSRP measurement delay. L1-RSRP，report is the delay in obtaining CSI (Channel State Information) report resources. uncertainty_MAC It is the time period from the first valid L1-RSRP report until the terminal (UE) receives the last activation command of the activation commands of PDCCH TCI and PDSCH TCI. FineTiming It is the time period from the time when the terminal completes the processing of the last activation command in the activation commands of PDCCH (Physical Downlink Control Channel) TCI (Transmission Configuration Indicator) and PDSCH (Physical Downlink Shared Channel) TCI until the time of the first complete available SSB corresponding to the TCI (PDCCH TCI or PDSCH TCI) state. uncertainty_SP It is the time period from the first valid L1-RSRP report until the activation command for activating the semi-persistent CSI-RS (Channel State Information Reference Signal) resource set for performing CQI (Channel Quality Indicator) reporting is received. The specific definition of each parameter in the above formula can refer to the existing standards and will not be repeated here.

[0034] T FirstSSB_MAX +15*T SMTC_MAX is the delay of the automatic gain control adjustment process, 8*Trs It is the delay of the cell search, frequency tracking and beam information acquisition process, which belongs to the relevant process of layer 3; T L1-RSRP,measure is the delay of the layer 1 reference signal receiving power measurement process, T L1-RSRP,report is the delay of the layer 1 reference signal received power reporting process, T HARQ +max(T uncertainty_MAC +T FineTiming +2ms,T uncertainty_SP ) is the delay of the transmission configuration indication activation, fine time tracking and other processes, which is part of the layer related process.

[0035] The executed layer 3 related process can be a non-enhanced layer 3 related process or an enhanced layer 3 related process. The receiving beam scanning coefficient (Rx Beam Sweeping Factor) used in the enhanced layer 3 related process is smaller than the receiving beam scanning coefficient used in the non-enhanced layer 3 related process. For example, the receiving beam scanning coefficient used in the enhanced layer 3 related process is an integer less than 8. As shown in the above formula, the 8 in 8*Trs represents the receiving beam scanning coefficient. The standard defines that the receiving beam scanning coefficient of 8 corresponds to the non-enhanced layer 3 related process, while the enhanced layer 3 related process uses a receiving beam scanning coefficient less than 8, which can reduce the delay of the layer 3 related process, thereby reducing the delay of the secondary cell activation process.

[0036] In step S104, layer 1 reference signal received power measurement is performed according to the reduced receive beam scanning coefficient.

[0037] According to the reduced receive beam scanning coefficient, layer 1 reference signal received power measurement is performed to enhance the existing layer 1 reference signal received power measurement.

[0038] In some embodiments, if the terminal has the capability to support the reduced receive beam scanning coefficient, the layer 1 reference signal received power measurement is performed according to the reduced receive beam scanning coefficient. If the terminal does not have the capability to support the reduced receive beam scanning coefficient, the layer 1 reference signal received power measurement is performed according to the receive beam scanning coefficient defined in the standard.

[0039] In some embodiments, the reduced receive beam scanning coefficient is less than the configured maximum number of receive beams. The reduced receive beam scanning coefficient is an integer less than 8, that is, the maximum number of receive beams can be 8. In some embodiments, the reduced receive beam scanning coefficient is 0 or the reduced receive beam scanning coefficient is an integer greater than 0 and less than 8. The reduced receive beam scanning coefficient is 0, which means that the layer 1 reference signal received power measurement is skipped (not performed). The delay of the secondary cell activation does not include the layer 1 reference signal received power measurement part.

[0040] As shown in the above formula, T L1-RSRP,measure is the delay of the layer 1 reference signal receiving power measurement process, T L1-RSRP,measure It is positively correlated with the receive beam scanning coefficient. For details, please refer to the existing standards. By reducing the receive beam scanning coefficient, T L1-RSRP,measure , thereby reducing the delay of the secondary cell activation process.

[0041] In some embodiments, layer one reference signal received power measurements are performed in frequency range 2 (FR2).

[0042] In some embodiments, when the layer one reference signal received power measurement is an SSB-based reference signal received power measurement and the SSB has been measured in the layer three partial correlation process, after executing the layer three partial correlation process, the layer one reference signal received power measurement is performed according to the reduced receive beam scanning coefficient.

[0043] In some embodiments, when the layer one reference signal received power measurement is a reference signal received power measurement based on CSI-RS, and the SSB and CSI-RS in the layer three part correlation process have a QCL (Quasi Co-Location) Type D relationship, after executing the layer three part correlation process, the layer one reference signal received power measurement is performed according to the reduced receiving beam scanning coefficient.

[0044] The QCL TypeD relationship describes the spatial receiver parameters, which refer to the beamforming characteristics of the downlink received signal, such as the main arrival angle, average arrival angle and other parameters. It is generally understood that the beam information is quasi-co-located, that is, it has similar beam information. For the CSI-RS-based layer 1 reference signal received power measurement, the CSI-RS configured for the layer 1 reference signal received power measurement has a QCL TypeD relationship with the reference signal (SSB) used in the layer 3 related process, that is, the layer 1 CSI-RS and the layer 3 SSB have quasi-co-located spatial receiver parameters, that is, they have similar beam information.

[0045] In some embodiments, when the CSI-RS resource type is configured as periodic CSI-RS resources or semi-persistent CSI-RS resources, and when the high-level parameter repetition corresponding to the resource set to which the CSI-RS resources belong is set to ON, the terminal uses a receive beam scanning coefficient less than 8 to perform receive beam scanning. The high-level parameter repetition corresponding to a resource set is set to ON to indicate that the terminal assumes that multiple CSI-RS resources in a resource set are transmitted using the same downlink spatial domain transmission filter, that is, multiple CSI-RS resources in a resource set are used for measurement of the same beam.

[0046] The above embodiment describes the relationship between the layer 1 reference signal and the layer 3 reference signal, which is more suitable for the case where the reduced receiving beam scanning coefficient is 0. For the case where the reduced receiving beam scanning coefficient is greater than 0 and less than 8, the relationship between the layer 1 reference signal and the layer 3 reference signal may not be limited.

[0047] In some embodiments, the number and width of the receiving beams are determined according to the reduced receiving beam scanning coefficient. According to the number and width of the receiving beams, the receiving beams are configured to measure the reference signal received power.

[0048] By using a reduced receive beam scanning coefficient, the width of the receive beam can be wider. For example, when the maximum number of receive beams is 8, when the terminal uses a reduced receive beam scanning coefficient of 4, 4 receive beams are used for measurement. When 8 receive beams are used for measurement to cover a 360-degree range, 4 receive beams can also be used for measurement to cover a 360-degree range, that is, the width of the receive beam is increased. The terminal can determine the number of receive beams and the width of the beam according to its own capabilities.

[0049] In the method of the above embodiment, the terminal performs layer 1 reference signal received power measurement according to the reduced receive beam scanning coefficient during the secondary cell activation process. Since the delay of the secondary cell activation process is positively correlated with the receive beam scanning coefficient, the reduced receive beam scanning coefficient can reduce the delay of the secondary cell activation process, and can reduce the energy consumption of the terminal, thereby improving the user experience.

[0050] Figure 2 Flow charts of other embodiments of the measurement method disclosed herein. Figure 2 As shown, the method of this embodiment is executed by the terminal and includes: steps S202 to S208.

[0051] In step S202, the terminal capability information is reported to the base station.

[0052] The terminal capability information includes: the receiving beam scanning coefficients supported by the terminal. The terminal can report the supported receiving beam scanning coefficients to the base station in the form of enumerated values ​​or value ranges.

[0053] For example, the enumeration value is in the form of {2, 4, 6} or {1, 2, 4, 6} or {0, 1, 2, 3, 4, 5, 6, 7} or other possible values ​​within the combination of integers less than 8. The value range is in the form of, for example, defining the maximum receive beam scanning coefficient as 8, and the reduced receive beam scanning coefficient as a range less than the maximum receive beam scanning coefficient.

[0054] The base station can instruct the terminal to report the supported receive beam scanning coefficients, or the terminal can actively report the supported receive beam scanning coefficients. The base station configures the corresponding transmit beams, etc. according to the receive beam scanning coefficients supported by the terminal. If the receive beam scanning coefficients supported by the terminal contain multiple values, the base station can determine a value and send it to the terminal, or the terminal can select a value and report it again or not.

[0055] In step S204, during the secondary cell activation process, layer 3 related processes are executed.

[0056] In step S206, layer 1 reference signal received power measurement is performed according to the reduced receive beam scanning coefficient.

[0057] The terminal may determine a value from the reported supported receive beam scanning coefficients as the reduced receive beam scanning coefficient.

[0058] In step S208, layer 1 reference signal received power reporting and subsequent processes are performed.

[0059] For example, the terminal performs layer 1 reference signal received power reporting, transmission configuration indication activation, fine time tracking, etc. to complete the secondary cell activation.

[0060] In the method of the above embodiment, the terminal reports the supported receiving beam scanning coefficient, and the base station can perform corresponding configuration. During the secondary cell activation process, the terminal performs layer 1 reference signal receiving power measurement according to the reduced receiving beam scanning coefficient, thereby reducing the delay of the secondary cell activation process and reducing the energy consumption of the terminal.
