[0002] With the continuous evolution of the network, the use of spectrum is becoming more and more abundant. The coordinated deployment of high, medium and low frequency bands is conducive to improving the coverage and capacity of the network. Carrier aggregation technology better realizes the coordinated deployment of high, medium and low frequency bands. At present, the more common carrier aggregation FR1 frequency band combinations in the network include 2.1G+1.8G CA, 900M+800M CA, etc., and FR2 frequency band combinations include 26G+28GCA, 26G+39G CA, etc. Carrier aggregation technology improves the flexibility of frequency band use and improves the overall performance of the communication network.

[0046] In order to solve the above problems, the embodiments of the present disclosure provide a method, apparatus, device and storage medium for activating a secondary cell.

[0047] For ease of understanding, the embodiment of the present disclosure will first introduce a method for activating a secondary cell.

[0048] It should be noted that the secondary cell activation method in the embodiment of the present disclosure is applied to a terminal.

[0049] Figure 1 A flow chart of a secondary cell activation method in an embodiment of the present disclosure is shown.

[0050] like Figure 1 As shown, the secondary cell activation method may include:

[0051] S110, determining whether the primary cell and the secondary cell in the inter-band carrier aggregation meet the secondary cell rapid activation conditions, which include that the primary cell and the secondary cell are co-located, that the time alignment error TAE index requirement is met, that the secondary cell is not configured with a transmission synchronization signal and a physical broadcast channel block SSB, and at least one of the boundary condition configurations.

[0052] In some embodiments, the carriers corresponding to the primary cell and the secondary cell are inter-band carrier aggregation, which may include: the carriers corresponding to the primary cell and the secondary cell may be FR1+FR1 CA, or FR1+FR2 CA, or FR2+FR2 CA.

[0053] In some embodiments, the quick activation conditions may include satisfying the quick activation conditions for the secondary cell, including co-location of the primary cell and the secondary cell, meeting the time alignment error TAE indicator requirements, the secondary cell not being configured with a transmission synchronization signal and a physical broadcast channel block SSB, and one or any combination of boundary condition configurations.

[0054] Exemplarily, the quick activation condition may include satisfying the quick activation condition of the secondary cell, including that the primary cell and the secondary cell are co-located, the secondary cell is not configured to transmit a synchronization signal and a physical broadcast channel block SSB, and boundary condition configuration.

[0055] In some embodiments, the quick activation conditions may include the above multiple situations, which will not be described one by one here.

[0056] In some embodiments, the terminal may include a terminal device, which may be various electronic devices, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, wearable devices, augmented reality devices, virtual reality devices, etc.

[0057] In some embodiments, the terminal may include a terminal with non-SSB configuration capability.

[0058] In some embodiments, the terminal without SSB configuration capability is used in the case where the terminal is not provided with SSB configuration and / or SMTC configuration of the secondary cell.

[0059] Exemplarily, the secondary cell is not configured to transmit SS / PBCH blocks, that is, the SSB configuration of the secondary cell is missing, for example, the absoluteFrequencySSB parameter is absent, so the terminal is not provided with the SSB configuration and / or SMTC configuration of the secondary cell.

[0060] In some embodiments, the carrier frequency band corresponding to the primary cell and the secondary cell is a 5G / 6G frequency band.

[0061] Exemplarily, the carrier frequency band corresponding to the primary cell and the secondary cell is a 4G refarmed to 5G / 6G frequency band, or a 5G / 6G new frequency band.

[0062] Exemplarily, the carrier frequency bands corresponding to the primary cell and the secondary cell are 4G refarmed to 5G / 6G bands, such as 2.1G+1.8G CA or 900M+800M CA. The medium and low frequency bands are deployed in LTE, and the hardware conditions, that is, the base station equipment meets the LTE inter-band TAE requirement of less than 260ns. After refarming to 5G / 6G, it naturally supports inter-band TAE of less than 260ns.

[0063] The carrier frequency bands corresponding to the primary cell and the secondary cell are the new 5G / 6G frequency bands. If the frequency domain interval between the two frequency bands in the inter-band CA frequency band combination is small, the requirement of inter-band TAE being within 260ns can also be met.

[0064] In some embodiments, the terminal may include the capability to support a non-SSB configuration.

[0065] Exemplarily, the terminal capability can be extended by the existing terminal capability to support the activation of secondary cells without SSB configuration for inter-band carrier aggregation, for example, the terminal supports the scellWithoutSSB configuration, and the scellWithoutSSB configuration is extended to the inter-band situation. Or the new terminal capability can be used to support the activation of secondary cells without SSB configuration for inter-band carrier aggregation, for example, a new terminal capability is defined to support the activation of secondary cells without SSB configuration for inter-band carrier aggregation, such as scellWithoutSSB_inter, which is used to support the terminal capability without SSB configuration in the inter-band CA scenario.

[0066] In some embodiments, the boundary conditions include: the reception time difference of the terminal between the secondary cell and the service cell with active inter-band carrier aggregation is within the second preset range, the reception power difference of the terminal between the secondary cell and the service cell with active inter-band carrier aggregation is within the third preset range, there is a quasi-co-site QCL relationship between the reference signals of the secondary cell and the service cell with active inter-band carrier aggregation, and at least one of the frequency domain intervals of two frequency bands in the frequency band combination of inter-band carrier aggregation is within the fourth preset range.

[0067] In some embodiments, the boundary conditions include: the reception time difference of the terminal between the secondary cell and the service cell with active inter-band carrier aggregation is within the second preset range, the reception power difference of the terminal between the secondary cell and the service cell with active inter-band carrier aggregation is within the third preset range, there is a quasi-co-location QCL relationship between the reference signals of the secondary cell and the service cell with active inter-band carrier aggregation, and the frequency domain interval between two frequency bands in the frequency band combination of inter-band carrier aggregation is within the fourth preset range, one or any combination of these.

[0068] In some embodiments, the reference signals of the secondary cell and the serving cell in which inter-band carrier aggregation is active have a quasi co-location QCL relationship including:

[0069] The reference signal of the secondary cell that is not configured with SSB has a QCL-TypeA relationship with the TRS of the secondary cell, and the TRS of the secondary cell further has a QCL-TypeC relationship with the SSB of the serving cell where inter-band carrier aggregation is active.

[0070] Exemplarily, the network configures the QCL type (QCL Type) through the TCI state (TCI state), and the QCL-TypeA type describes the Doppler shift, Doppler spread, average delay and delay spread, and the QCL-TypeC describes the Doppler shift and average delay. The reference signal of the secondary cell that is not configured with SSB has a QCL-TypeA relationship with the TRS of the secondary cell. For example, the CSI-RS signal of the secondary cell that is not configured with SSB has a QCL-TypeA relationship with the TRS of the secondary cell. Then the terminal considers that the Doppler shift, Doppler spread, average delay and delay spread of the two reference signals are the same, that is, the time / frequency information is the same. The TRS of the secondary cell is further in a QCL-TypeC relationship with the SSB of the service cell where inter-band carrier aggregation is active. The terminal considers that the Doppler shift and average delay of the two reference signals are the same, that is, the time / frequency information is the same.

[0071] In some embodiments, the frequency domain interval between two frequency bands in the frequency band combination of inter-band carrier aggregation is within a fourth preset range, wherein the fourth preset range may include a user-defined range. Exemplarily, the fourth preset range includes less than 1 GHz, less than 2 GHz, or a specific frequency band combination may be applicable, such as CA_n5-n8 (800M+900M CA), CA_n1-n3 (2.1G+1.8GCA).

[0072] S120: When the primary cell and the secondary cell meet the secondary cell fast activation condition, complete activation of the secondary cell.

[0073] In some embodiments, the receiving power difference of the terminal between the secondary cell and the serving cell where inter-band carrier aggregation is active is within a third preset range, wherein the third preset range may include a user-defined range, and an exemplary third preset range may be a range less than 6dB.

[0074] For example, when the two frequency bands in the inter-band CA frequency band combination share the same RU, the power spectrum density (PSD) of the transmission power is the same or close. Since the two frequency bands are close and the path loss (PL) is similar, the receiving power difference of the terminal between the secondary cell and the service cell where the inter-band carrier aggregation is active can be controlled within a certain range.

[0075] In some embodiments, the second preset range may be a range defined by a user. For example, the second preset range may include less than 260 ns.

[0076] In some embodiments, when the fast activation condition is determined, the terminal can complete the activation of the secondary cell only when the primary cell and the secondary cell meet all conditions included in the fast activation condition.

[0077] In some embodiments, the secondary cell activation method based on the embodiments of the present disclosure can avoid the need for automatic gain control adjustment, cell search, layer 1 reference signal received power measurement and reporting, transmission configuration indication activation, fine time tracking and other processes in conventional secondary cell activation.

[0078] Exemplarily, the secondary cell activation method in the embodiment of the present disclosure can avoid the above process, thereby reducing the delay of secondary cell activation to 3 ms.

[0079] The secondary cell activation method provided in the embodiment of the present disclosure determines the rapid activation conditions of the primary cell and the secondary cell in the inter-band carrier aggregation, and completes the activation of the secondary cell when the primary cell and the secondary cell meet the rapid activation conditions of the secondary cell, thereby avoiding the problem of complicated steps and long delay of conventional secondary cell activation.

[0080] Figure 2 A flow chart of another secondary cell activation method in an embodiment of the present disclosure is shown.

[0081] like Figure 2 As shown, the secondary cell activation method may include:

[0082] S210, determining whether the primary cell and the secondary cell in the inter-band carrier aggregation meet the secondary cell rapid activation conditions, and meeting the secondary cell rapid activation conditions includes that the carrier frequency bands corresponding to the primary cell and the secondary cell are implemented on the same baseband and / or the same radio frequency, the time alignment error TAE indicator requirements are met, the secondary cell is not configured with a transmission synchronization signal and a physical broadcast channel block SSB, and at least one of the boundary condition configurations.

[0083] In some embodiments, whether the primary cell and the secondary cell are co-deployed may be determined based on whether carrier frequency bands corresponding to the primary cell and the secondary cell are implemented on the same baseband and / or the same radio frequency.

[0084] S220: When the primary cell and the secondary cell meet the secondary cell fast activation condition, complete activation of the secondary cell.

[0085] The secondary cell activation method provided in the embodiment of the present disclosure determines the rapid activation conditions of the primary cell and the secondary cell in the inter-band carrier aggregation, and completes the activation of the secondary cell when the primary cell and the secondary cell meet the rapid activation conditions of the secondary cell, thereby avoiding the problem of complicated steps and long delay of conventional secondary cell activation.

[0086] Figure 3 A flow chart of another secondary cell activation method in an embodiment of the present disclosure is shown.

[0087] like Figure 3 As shown, the secondary cell activation method may include:

[0088] S310, determining whether the primary cell and the secondary cell in the inter-band carrier aggregation meet the secondary cell quick activation conditions, and meeting the secondary cell quick activation conditions includes that the primary cell and the secondary cell are co-located, the inter-band carrier aggregation time alignment error between the primary cell and the secondary cell is within a first preset range, the secondary cell is not configured with a transmission synchronization signal and a physical broadcast channel block SSB, and at least one of the boundary condition configurations.

[0089] In some embodiments, whether the primary cell and the secondary cell meet the TEA indicator requirement can be determined based on determining whether the inter-band carrier aggregation time alignment error of the primary cell and the secondary cell is within a first preset range.

[0090] In some embodiments, the first preset range may be a value less than 3 us. For example, the first preset range may be 260 ns, 2.34 us, or 65 ns.

[0091] S320: When the primary cell and the secondary cell meet the secondary cell fast activation condition, activation of the secondary cell is completed.

[0092] In some embodiments, the TAE indicator can be used as an optional TAE indicator, applicable to the above scenario. For example, for inter-band carrier aggregation, TAE not exceeding 3us is a requirement that must be met, and TAE not exceeding 260ns is an optional indicator requirement. Or the TAE indicator can be an optional value based on the manufacturer's declaration. For example, the value can be taken based on the table declared by the manufacturer.

[0093] The secondary cell activation method provided in the embodiment of the present disclosure determines the rapid activation conditions of the primary cell and the secondary cell in the inter-band carrier aggregation, and completes the activation of the secondary cell when the primary cell and the secondary cell meet the rapid activation conditions of the secondary cell, thereby avoiding the problem of complicated steps and long delay of conventional secondary cell activation.

[0094] Figure 4 A flow chart of another secondary cell activation method in an embodiment of the present disclosure is shown.

[0095] like Figure 4 As shown, the secondary cell activation method may include:

[0096] S410, determining a second preset range based on the TAE indicator requirement.

[0097] In some embodiments, the active serving cell may be a primary cell or other active secondary cells.

[0098] In some embodiments, the RTD value between the secondary cell and the serving cell where inter-band carrier aggregation is active is associated with the TAE value.

[0099] Exemplarily, RTD is composed of TAE, propagation delay, processing delay, etc. In scenarios where propagation delay and processing delay can be ignored, RTD mainly depends on TAE. For example, if the optional TAE requirement is 260ns, then RTD is controlled within 260ns. Exemplarily, the primary cell and the secondary cell are carrier aggregation between frequency bands, and the frequency domain interval between the two frequency bands is small, which can be implemented in the same baseband and / or the same radio frequency, then the propagation delay in the air interface and the delay in terminal processing can be ignored.

[0100] S420, determining whether the primary cell and the secondary cell in the inter-band carrier aggregation meet the secondary cell rapid activation conditions, which include that the primary cell and the secondary cell are co-located, that the time alignment error TAE index requirement is met, that the secondary cell is not configured with a transmission synchronization signal and a physical broadcast channel block SSB, and at least one of the boundary condition configurations.

[0101] S430: When the primary cell and the secondary cell meet the secondary cell fast activation condition, activation of the secondary cell is completed.

[0102] The secondary cell activation method provided in the embodiment of the present disclosure determines the rapid activation conditions of the primary cell and the secondary cell in the inter-band carrier aggregation, and completes the activation of the secondary cell when the primary cell and the secondary cell meet the rapid activation conditions of the secondary cell, thereby avoiding the problem of complicated steps and long delay of conventional secondary cell activation.

[0103] Based on the same inventive concept, the present disclosure also provides a secondary cell activation device, such as the following embodiment. Since the principle of solving the problem in the device embodiment is similar to that in the above method embodiment, the implementation of the device embodiment can refer to the implementation of the above method embodiment, and the repeated parts will not be repeated.
