[0099] Figure 1A is a schematic diagram of the architecture of a communication system according to an embodiment of this application.
[0100] As shown in Figure 1A, the communication system 100 includes a terminal 101 and a network device 102.
[0101] In some embodiments, terminal 101 includes, for example, at least one of the following: mobile phone, wearable device, Internet of Things (IoT) device, narrowband Internet of Things (NB-IoT) device, satellite communication device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, wireless terminal device in smart home, and red-capped terminal, but is not limited thereto.

[0103] In some embodiments, the technical solutions of this application can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this application can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.
[0104] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.
[0105] It is understood that the communication system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions proposed in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in the embodiments of this application are also applicable to similar technical problems.
[0106] The following embodiments of this application can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.
[0107] The embodiments of this application can be applied to 4G and 5G NR dual connectivity (E-UTRAN-NR Dual Connectivity, EN-DC), standalone NR carrier aggregation, 5G NR and 4G dual connectivity (NR-E-UTRANDual Connectivity, NE-DC), NR-NRDual Connectivity, NR-DC, Non-terrestrial Network (NTN), Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), 6G new radio (NR), Future Radio Access (FRA), and New-Radio Access technologies. Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20. Ultra-Wideband (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Narrow Band IoT (NB-IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G / 6G).
[0108] In some embodiments of a wireless communication system, carrier aggregation (CA) technology can be used to improve data transmission rate and system capacity. This technology combines multiple carriers to form a wider transmission bandwidth, thereby increasing data transmission rate, spectral efficiency, and system capacity. These carriers can be different carriers within the same frequency band or carriers from different frequency bands.
[0109] In some embodiments, terminal 101 may be allowed to connect simultaneously to two different network devices 102 or different cells of the same network device 102, and perform data transmission and signaling interaction through two connection paths. This allows the resources of two connections to be utilized, thereby improving the reliability and efficiency of data transmission. In a dual-connectivity system, terminal 101 is configured with a primary cell (PCell) and at least one secondary cell (SCell).
[0110] In some embodiments, as network conditions and service requirements may change continuously, an adaptive approach to general signal / channel transmission may be proposed. Examples include: a time-domain adaptive Synchronization Signal Block (SSB), such as adjusting its periodicity; a time-domain adaptive Physical Random Access Channel (PRACH), etc.
[0111] In some embodiments, the SSB includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH).
[0112] In some embodiments, network device 102 can trigger both a SCell activation command and an SSB adaptation command. As shown in FIG1B, terminal 101 receives the aforementioned SCell activation command in slot n and the SSB adaptation command in slot k. After network device 102 sends the adaptive SSB, terminal 101 may miss one of the SSBs. These undetected SSBs should be considered valid samples for SCell activation, resulting in terminal 101 using actually fewer valid SSBs during the SCell activation process. If current requirements regarding SCell activation are followed, the corresponding test cases may fail.
[0113] Regarding Figure 1B, it should be noted that after network device 102 triggers the SSB adaptation command, it can adjust the SSB period and send SSBs according to the new period. SSBs that should have been sent according to the original period after this adaptation command will not be sent. For terminal 101, since it has not received the SSB adaptation command from the network before time slot k, it cannot receive the SSBs sent according to the adapted period.
[0114] The communication method, communication equipment, communication system, storage medium, and program products provided in this application will be described in detail below with reference to the accompanying drawings.

[0181] Figure 3A is an interactive schematic diagram of a communication method according to an embodiment of this application. As shown in Figure 3A, the embodiment of this application relates to a communication method, which includes:
[0182] In step S3101, network device 102 sends first information and second information.
[0183] In some embodiments, the first information described above is used to instruct terminal 101 to activate secondary cell SCell.
[0184] In some embodiments, the second information described above is used to configure the first synchronization signal block (SSB).
[0185] The first SSB mentioned above is used for the activation of the SCell mentioned above.
[0186] In some embodiments, terminal 101 can correctly activate the aforementioned SCell based on the first SSB.
[0187] In some embodiments, terminal 101 receives the first information at a first time point and receives the second information at a second time point. The second time point is no later than the first time point. As an example, it can be shown in FIG2B.
[0188] In some embodiments, the first information and the second information are sent simultaneously by the network device, and the first information is received at a first time point, and the second information is received at a second time point. The second time point is no later than the first time point. As an example, it can be shown in Figure 2C.
[0189] In some embodiments, the first time point mentioned above is the starting point of the SCell activation delay of terminal 101.
[0190] In some embodiments, the first time point mentioned above is the starting point at which terminal 101 activates SCell.
[0191] In some embodiments, the method further includes: receiving a second SSB sent by a network device before the terminal receives the second information. The period corresponding to the second SSB is different from the period corresponding to the first SSB.
[0192] In some embodiments, the first SSB described above is an adaptive SSB.
[0193] In some embodiments, the method further includes: the terminal 101 may send a Channel State Information (CSI) report to the network device based on the first SSB.
[0194] In some embodiments, network device 102 may readjust the period corresponding to the first SSB. Network device 102 may also send third information to the terminal, the third information being used to instruct network device 102 to readjust the period corresponding to the first SSB.
[0195] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
[0196] The following is an exemplary description of the methods described in the above embodiments.
[0197] In some embodiments, network device 102 can trigger both a SCell activation command and an SSB adaptation command. As shown in FIG1B, terminal 101 may receive the aforementioned SCell activation command in time slot n and the SSB adaptation command in time slot k. The processing time of the SSB adaptation command (MAC) is longer than the processing time of the secondary cell activation command. Therefore, after network device 102 sends the adaptive SSB, terminal 101 may miss one of the SSBs. Terminal 101 needs to complete the secondary cell activation based on the adaptively adjusted SSB, given the limited measurement opportunities. These undetected SSBs should be considered valid samples for SCell activation, resulting in terminal 101 using effectively fewer valid SSBs during the SCell activation process. If current requirements regarding SCell activation are followed, the corresponding test cases may fail.
[0198] In some embodiments, in order to solve the problems that may occur in the above embodiments, the requirement for SCell activation delay can be defined based on the SSB period after SSB adaptation: if the UE receives the SSB adaptation command (MAC) no later than the start point of the SCell delay, the start point of the SCell delay can be the time slot in which the UE receives the SCell activation command.
[0199] In other words, in some embodiments, for SSB-based adaptive SCell activation, the UE should receive the adaptive SSB command in slot k earlier than it receives the SCell activation command in slot n. Otherwise, a longer activation delay is expected due to missed SSB opportunities. As an example, this can be illustrated in Figure 2B.
[0200] In some embodiments, to address potential issues in the above embodiments, the SSB adaptive command and the SCell activation command can be combined. That is, in some embodiments, for SSB adaptive SCell activation, where the network expects the SCell activation MAC command and the SSB adaptive MAC command to be together, the starting point of the SCell delay can be the time slot n when the UE receives the SCell activation command. As an example, this can be illustrated in Figure 2C.
[0201] In some embodiments, unless contradictory, the optional implementations in this embodiment can be implemented as independent embodiments, and the optional implementations in this embodiment can also be combined arbitrarily. The technical features of different feasible implementations in this embodiment can be combined to form new optional implementations based on their inherent logical relationships.
[0202] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
[0203] This application also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed, which includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed, which includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.
[0204] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.
[0205] In this application embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
