Description

A communication method and apparatus

[0001] This application claims priority to Chinese Patent Application No. 202510020467.0, filed on January 3, 2025, entitled "A Communication Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method and apparatus. Background Technology

[0003] In the field of communications, carrier aggregation (CA) technology can be used to aggregate spectrum resources of the same or different frequency bands to improve network resource utilization.

[0004] In one scenario, when the terminal does not have a receive (RX) capability that matches the number of carriers, the terminal can switch RX radio frequency channels to achieve the effect of switching transmissions on multiple carriers.

[0005] However, since a terminal can only transmit data on one carrier at a time, and different carriers may interfere with each other, the data transmission performance of the communication system is reduced. Summary of the Invention

[0006] This application provides a communication method and apparatus that can effectively determine that the terminal should transmit data on the second carrier to be switched at this moment, thereby improving the data transmission performance of the communication system.

[0007] Firstly, a communication method is provided. This method can be executed by a terminal, or by a component of the terminal, such as a processor, chip, or chip system. It can also be implemented by a logic module or software capable of performing all or part of the terminal's functions. The following description uses the example of the communication method being executed by a terminal. The communication method includes:

[0008] The priority of the first information transmitted by the terminal and the network device on the first carrier is determined, as well as the priority of the second information transmitted by the network device on the second carrier to which the terminal needs to switch; based on the priority of the first information and the priority of the second information, the switch from the first carrier to the second carrier is determined; and the second information is transmitted with the network device on the second carrier.

[0009] In this application, regarding the first information transmitted by the terminal and network equipment on the first carrier, and the second information that the terminal needs to switch to on the second carrier to transmit with the network equipment, the terminal can determine the priority of the first information and the priority of the second information. Based on the priorities of the first and second information, the terminal can determine to prioritize the transmission of the second information; that is, the terminal can determine to switch from the first carrier to the second carrier and transmit the second information with the network equipment on the second carrier. This effectively determines that data should be transmitted on the second carrier to be switched to at that moment, improving the data transmission performance of the communication system.

[0010] In one possible design, determining the switch from the first carrier to the second carrier based on the priority of the first information and the priority of the second information specifically includes: determining the switch from the first carrier to the second carrier when the priority of the second information is higher than or equal to the priority of the first information.

[0011] Based on this possible design, when the priority of the second information is higher than that of the first information, it indicates that the second information has a higher priority, and the terminal can prioritize transmitting the second information. When the priority of the second information is equal to that of the first information, it indicates that the priority of the second information is the same as that of the first information. Since the terminal needs to switch to the second carrier to transmit the second information with the network device, the terminal can also prioritize transmitting the second information. In this way, when the terminal determines to switch from the first carrier to the second carrier, it can ensure that the terminal prioritizes transmitting the information with higher priority / importance after the carrier switch (i.e., the second information), thus improving the reliability of the communication system.

[0012] In one possible design, the determination of the priority of the first information transmitted by the terminal and the network device on the first carrier, and the priority of the second information transmitted by the network device on the second carrier that the terminal needs to switch to, specifically includes: when the terminal needs to transmit the second information on the second carrier, and the first information has not been fully transmitted on the first carrier, determining the priority of the first information and the priority of the second information.

[0013] Based on this possible design, when a terminal needs to transmit second information on a second carrier, and the first information has not been fully transmitted on the first carrier, it means that the terminal needs to transmit both the first and second information on the first and second carriers. Since the terminal can only transmit data on one carrier at a time, it needs to determine the priority of the first and second information to decide whether to prioritize transmitting the second information or the untransmitted portion of the first information. Furthermore, since some of the first information has already been transmitted, even if the priority of the second information is the same as that of the first information, the terminal can still prioritize transmitting the untransmitted second information, avoiding information loss between the terminal and network equipment and ensuring that more important information is transmitted.

[0014] In one possible design, determining the priority of the first information transmitted by the terminal and network device on the first carrier specifically includes: obtaining the type of the first information; and determining the priority of the first information based on the type of the first information.

[0015] Based on this possible design, since different types of information often imply different levels of importance, for example, control plane information is more important than user plane information, and therefore has a higher priority. Thus, the terminal can accurately determine the priority of the first piece of information based on its type.

[0016] In one possible design, the type of the aforementioned first information includes at least one of the following: a type of periodic information, a type of user information, a type of non-periodic information, a type of on-demand triggered information, a type of control information, or a type of network access information.

[0017] Based on this possible design, since different types of information often imply varying degrees of importance, for example, the fixed transmission period of periodic information is predefined or configured via RRC signaling, while aperiodic information is triggered on demand / actively by network devices. Aperiodic information is more important than periodic information, and therefore has a higher priority. Thus, for the first piece of information, the terminal can accurately determine its priority based on the different types it includes.

[0018] In one possible design, determining the priority of the first information based on its type specifically includes: when the type of the first information is periodic information or user information, the priority of the first information is determined to be the first priority; when the type of the first information is non-periodic information, on-demand triggered information, control information, or network access information, the priority of the first information is determined to be the second priority, which is higher than the first priority.

[0019] Based on this possible design, when the type of the first information is periodic information, it indicates that the first information is predefined or configured, and the terminal can determine that the first information has a low priority, specifically the first priority. When the type of the first information is user information, it indicates that the first information has a low latency requirement, and the terminal can also determine that the first information has a low priority. However, when the type of the first information is non-periodic information or on-demand triggered information, it indicates that the first information is triggered on-demand / actively by the network device, and the terminal can determine that the first information has a high priority, specifically the second priority. When the type of the first information is control information, it indicates that the first information carries network scheduling commands, and the terminal can also determine that the first information has a high priority. When the type of the first information is network access information, it indicates that the first information is key information for the terminal to access the network, and the terminal can determine that the first information has a high priority. In other words, according to the different types of the first information, the terminal can accurately and effectively determine the priority of the first information.

[0020] In one possible design, the communication method further includes: when the type of the first information is periodic information or user information, the terminal determines that the priority of the second information is higher than or equal to the priority of the first information; when the type of the first information is non-periodic information, on-demand triggered information, control information, or network access information, the terminal determines that the priority of the second information is lower than the priority of the first information.

[0021] Based on this possible design, when the first information is of a periodic type, it indicates that the first information is predefined or configured and has a low priority. The terminal can determine that the second information has a higher or equal priority than the first information, meaning the second information has a higher priority. When the first information is of a user information type, it indicates that the first information has a lower latency requirement and also has a lower priority. The terminal can also determine that the second information has a higher or equal priority than the first information. When the first information is of a non-periodic type or an on-demand triggered type, it indicates that the first information is triggered on-demand / actively by the network device and has a higher priority. The terminal can determine that the second information has a lower priority than the first information, meaning the second information has a lower priority. When the first information is of a control information type, it indicates that the first information carries network scheduling commands, and the terminal can also determine that the second information has a lower priority than the first information. When the first information is of a network access information type, it indicates that the first information is critical for the terminal to access the network, and the terminal can also determine that the second information has a lower priority than the first information. By using different types of first information, the terminal can determine the priority of the second information relative to the first information, thereby ensuring that information of higher importance is transmitted first.

[0022] In one possible design, the aforementioned periodic information is any one of the following signals with a fixed transmission period: SSB signal, SIB1 signal, CSI-RS signal, TRS signal, or SRS signal.

[0023] Based on this possible design, since the fixed transmission periods of SSB, SIB1, CSI-RS, TRS, and SRS signals are predefined by the protocol between the terminal and the network device or configured via RRC signaling, these signals have lower priority. When these signals are being transmitted on the first carrier, the terminal can switch from the first carrier to the second carrier to transmit the second information with the network device on the second carrier, ensuring that information of higher importance is transmitted first.

[0024] In one possible design, the aforementioned user information is either a PDSCH signal or a PUSCH signal.

[0025] Based on this possible design, since the PDSCH signal and PUSCH signal represent user information transmitted from the base station to the terminal and from the terminal to the base station, respectively, and this user information has low latency requirements, it has a low priority. When this user information is being transmitted on the first carrier, the terminal can switch from the first carrier to the second carrier to transmit the second information with the network equipment on the second carrier, thus ensuring the effective transmission of more important information.

[0026] In one possible design, the aforementioned non-periodic information is any one of the following information with a non-fixed transmission period: CSI-RS signal, TRS signal, or SRS signal.

[0027] Based on this possible design, since the CSI-RS, TRS, and SRS signals, which have non-fixed transmission periods, are information triggered on demand / actively by network devices, these signals have high priority. When these signals are being transmitted on the first carrier, the terminal does not need to switch from the first carrier to the second carrier, but continues to transmit these high-priority signals with the network device on the first carrier, thus ensuring the priority transmission of important, on-demand triggered information.

[0028] In one possible design, the aforementioned on-demand triggering information is any one of the following on-demand triggering information: the SSB signal or the SIB1 signal.

[0029] Based on this possible design, since the on-demand triggered SSB and SIB1 signals are information triggered on demand / actively by the network device, these signals have relatively high priority. When these signals are being transmitted on the first carrier, the terminal does not need to switch from the first carrier to the second carrier, but continues to transmit these high-priority signals with the network device on the first carrier, thereby ensuring that the most important, on-demand triggered information is transmitted first.

[0030] In one possible design, the aforementioned control information is either a PDCCH signal or a PUCCH signal.

[0031] Based on this possible design, since the PDCCH and PUCCH signals represent control information transmitted from the base station to the terminal and from the terminal to the base station, respectively, and the control information carries network scheduling commands, it is of high importance to the terminal. Therefore, this control information has a high priority. When this control information is being transmitted on the first carrier, the terminal does not need to switch from the first carrier to the second carrier, but continues to transmit this high-priority / high-importance control information with the network equipment on the first carrier, ensuring the effective transmission of high-importance information.

[0032] In one possible design, the aforementioned network access information is a PRACH signal.

[0033] Based on this possible design, since the PRACH signal is used to assist the terminal in establishing a connection with the network during initial access, it is crucial information for the terminal's network access and therefore has a high priority. When a PRACH signal is being transmitted on the first carrier, the terminal does not need to switch from the first carrier to the second carrier; instead, it continues to transmit higher-priority / more important PRACH signals with the network device on the first carrier. This ensures the communication connection between the terminal and the network and improves the terminal's communication stability.

[0034] In one possible design, the aforementioned second information is information used to measure the channel state.

[0035] Based on this possible design, after the terminal switches from the first carrier to the second carrier, it indicates that the priority of the information used to measure the channel state (i.e., the second information) is higher than or equal to the priority of the first information. In other words, the information used to measure the channel state has a higher priority / importance. The terminal can prioritize transmitting the information used to measure the channel state on the second carrier, thereby enabling the terminal to prioritize the channel state measurement process to ensure the stability of the channel state.

[0036] In one possible design, the information used to measure the channel state is a CSI-RS signal.

[0037] Based on this possible design, after the terminal switches from the first carrier to the second carrier, it indicates that the priority of the CSI-RS signal is higher than or equal to the priority of the first information. That is, the CSI-RS signal has a higher priority / importance. The terminal can prioritize transmitting the CSI-RS signal on the second carrier, thereby enabling the terminal to prioritize the downlink channel state measurement operation, so as to prioritize the downlink synchronization / measurement process and improve the stability of the communication system.

[0038] In one possible design, the frequency band corresponding to the first carrier is different from the frequency band corresponding to the second carrier.

[0039] Based on this possible design, since different carriers correspond to different frequency bands, the terminal can switch from the frequency band corresponding to the first carrier to the frequency band corresponding to the second carrier by switching from the first carrier to the second carrier. Thus, the terminal can transmit relevant data through the corresponding frequency band, ensuring the effective transmission of important data.

[0040] Secondly, a communication method is provided. This communication method can be executed by a terminal, or by a component of the terminal, such as the terminal's processor, chip, or chip system, or by a logic module or software capable of implementing all or part of the terminal's functions. The following description uses the example of the communication method being executed by a terminal. The communication method includes:

[0041] The terminal receives a first instruction from a network device, the first instruction being used to instruct the terminal to switch from a first carrier to a second carrier, the first carrier being used to transmit first information; based on the first instruction and a second instruction, the terminal switches from the first carrier to the second carrier, the second instruction being an instruction to instruct the terminal to transmit the first information; and transmits second information with the network device on the second carrier.

[0042] In this application, after receiving a first instruction from a network device, the terminal can switch from a first carrier to a second carrier based on the first and second instructions, thereby transmitting second information with the network device on the second carrier. This ensures that more important data can be effectively transmitted and improves the stability of the communication system.

[0043] In one possible design, the above-mentioned switching from the first carrier to the second carrier based on the first instruction and the second instruction specifically includes: when the transmission direction of the first information is uplink transmission, determining the configuration type of the first instruction and the configuration type of the second instruction; and switching from the first carrier to the second carrier based on the configuration type of the first instruction and / or the configuration type of the second instruction.

[0044] Based on this possible design, when the transmission direction of the first information is uplink, it indicates that the first information is information sent by the terminal to the network device. Since the terminal may not expect to receive downlink transmission instructions from the network device while simultaneously sending information to it, the terminal needs to determine the configuration type of both the first and second instructions. Because the priority / importance of the first and second instructions can be determined based on their configuration types, the terminal can execute operations related to the higher-priority / important first instruction, i.e., switching from the first carrier to the second carrier, ensuring the effective transmission of more important data.

[0045] In one possible design, the configuration type is either static or dynamic.

[0046] Based on this possible design, different configuration types often imply varying degrees of importance for instructions. For example, regarding a dynamically configured first instruction and a statically configured second instruction, the dynamically configured first instruction is more important than the statically configured second instruction; therefore, the dynamically configured first instruction has a higher priority than the statically configured second instruction. Thus, for both the first and second instructions, the terminal can determine their importance / priority based on their specific configuration types, and switch from the first carrier to the second carrier according to the higher-priority first instruction, ensuring that information with higher priority is transmitted first.

[0047] In one possible design, the switching from the first carrier to the second carrier based on the configuration type of the first instruction and / or the configuration type of the second instruction specifically includes: when the configuration type of the second instruction is static configuration, switching from the first carrier to the second carrier.

[0048] Based on this possible design, when the configuration type of the second instruction is static configuration, it means that the second instruction is pre-configured by the network device. In this case, regardless of whether the configuration type of the first instruction is static or dynamic configuration, the priority of the second instruction is lower than that of the first instruction. Thus, the terminal can switch from the first carrier to the second carrier based on the first instruction, ensuring that the second information with higher priority / importance is transmitted first.

[0049] In one possible design, the switching from the first carrier to the second carrier based on the configuration type of the first instruction and / or the configuration type of the second instruction specifically includes: when the configuration type of the second instruction is dynamic configuration and the configuration type of the first instruction is dynamic configuration, obtaining a first time and a second time, wherein the first time is the time when the terminal receives the first instruction and the second time is the time when the terminal receives the second instruction; and when the first time is before the second time, switching from the first carrier to the second carrier.

[0050] Based on this possible design, since dynamic configuration is performed on demand / actively by network devices, when both the configuration type of the second instruction and the configuration type of the first instruction are dynamic configurations, it indicates that both the second and first instructions have higher priorities. The terminal can prioritize the first instruction received / detected and thus perform the relevant operations. At this time, the terminal can obtain the times at which it received the two instructions, i.e., the first moment and the second moment. When the first moment occurs before the second moment, it indicates that the terminal received the first instruction first, and therefore can execute the instructions in the first instruction, i.e., switching from the first carrier to the second carrier. This ensures that the terminal executes the network device's dynamic configuration instructions in chronological order, improving the reliability of the communication system.

[0051] In one possible design, the type of the aforementioned first information includes at least one of the following: a type of periodic information or a type of user information.

[0052] In one possible design, the aforementioned periodic information is any one of the following signals with a fixed transmission period: SSB signal, SIB1 signal, CSI-RS signal, TRS signal, or SRS signal.

[0053] In one possible design, the aforementioned user information is either a PDSCH signal or a PUSCH signal.

[0054] In one possible design, the aforementioned second information is information used to measure the channel state.

[0055] In one possible design, the information used to measure the channel state is a CSI-RS signal.

[0056] In one possible design, the frequency band corresponding to the first carrier is different from the frequency band corresponding to the second carrier.

[0057] The technical effects of some design methods in the second aspect can be seen in the technical effects of the corresponding design methods in the first aspect above, and will not be repeated here.

[0058] Thirdly, a communication method is provided. This method can be executed by a network device, or by a component of the network device, such as the network device's processor, chip, or chip system, or by a logic module or software capable of implementing all or part of the network device. The following description uses the execution of this communication method by a network device as an example. This communication method includes:

[0059] The priority of the first information transmitted by the terminal and the network device on the first carrier is determined, as well as the priority of the second information transmitted by the network device on the second carrier to which the terminal needs to switch. Based on the priority of the first information and the priority of the second information, a first instruction is sent to the terminal, which instructs the terminal to switch from the first carrier to the second carrier.

[0060] In this application, regarding the first information transmitted by the terminal and network device on the first carrier, and the second information that the terminal needs to switch to for transmission on the second carrier, the network device can determine the priority of the first information and the priority of the second information. Based on the priorities of the first and second information, it can determine the priority for transmitting the second information. That is, the network device can send a first instruction to the terminal to instruct it to switch from the first carrier to the second carrier. This effectively determines that the terminal should transmit data on the second carrier to be switched at that moment, improving the data transmission performance of the communication system.

[0061] In one possible design, sending a first instruction to the terminal based on the priority of the first information and the priority of the second information specifically includes: sending the first instruction to the terminal when the priority of the second information is higher than or equal to the priority of the first information.

[0062] Based on this possible design, when the priority of the second information is higher than that of the first information, it means the second information has a higher priority, and the terminal can prioritize transmitting the second information. When the priority of the second information is equal to that of the first information, it means the priority of the second information is the same as that of the first information. Since the terminal needs to switch to the second carrier to transmit the second information with the network device, the terminal can also prioritize transmitting the second information. In this case, the network device can send a first instruction to the terminal to instruct the terminal to switch from the first carrier to the second carrier, which can ensure that the terminal prioritizes transmitting the higher-priority information, i.e., the second information, after the carrier switch, thus improving the reliability of data transmission.

[0063] In one possible design, the determination of the priority of the first information transmitted by the terminal and the network device on the first carrier, and the priority of the second information transmitted by the network device on the second carrier that the terminal needs to switch to, specifically includes: when the terminal needs to transmit the second information on the second carrier, and the first information has not been fully transmitted on the first carrier, determining the priority of the first information and the priority of the second information.

[0064] In one possible design, determining the priority of the first information transmitted by the terminal and network device on the first carrier specifically includes: obtaining the type of the first information; and determining the priority of the first information based on the type of the first information.

[0065] In one possible design, the type of the aforementioned first information includes at least one of the following: a type of periodic information, a type of user information, a type of non-periodic information, a type of on-demand triggered information, a type of control information, or a type of network access information.

[0066] In one possible design, the communication method further includes: when the type of the first information is periodic information or user information, the network device determines that the priority of the second information is higher than or equal to the priority of the first information; when the type of the first information is non-periodic information, on-demand triggered information, control information, or network access information, the network device determines that the priority of the second information is lower than the priority of the first information.

[0067] In one possible design, determining the priority of the first information based on its type specifically includes: when the type of the first information is periodic information or user information, the priority of the first information is determined to be the first priority; when the type of the first information is non-periodic information, on-demand triggered information, control information, or network access information, the priority of the first information is determined to be the second priority, which is higher than the first priority.

[0068] In one possible design, the aforementioned periodic information is any one of the following signals with a fixed transmission period: SSB signal, SIB1 signal, CSI-RS signal, TRS signal, or SRS signal.

[0069] In one possible design, the aforementioned user information is either a PDSCH signal or a PUSCH signal.

[0070] In one possible design, the aforementioned non-periodic information is any one of the following information with a non-fixed transmission period: CSI-RS signal, TRS signal, or SRS signal.

[0071] In one possible design, the aforementioned on-demand triggering information is any one of the following on-demand triggering information: the SSB signal or the SIB1 signal.

[0072] In one possible design, the aforementioned control information is either a PDCCH signal or a PUCCH signal.

[0073] In one possible design, the aforementioned network access information is a PRACH signal.

[0074] In one possible design, the aforementioned second information is information used to measure the channel state.

[0075] In one possible design, the information used to measure the channel state is a CSI-RS signal.

[0076] In one possible design, the frequency band corresponding to the first carrier is different from the frequency band corresponding to the second carrier.

[0077] The technical effects of some design methods in the third aspect can be seen in the technical effects of the corresponding design methods in the first aspect above, and will not be repeated here.

[0078] Fourthly, a communication device is provided for implementing the various methods described above.

The transceiver module may consist of transceiver circuits, transceivers, transceivers, or communication interfaces. The processing module can be used to implement the processing functions in any of the above aspects and their possible implementations.

[0080] In some possible designs, the transceiver module includes a sending module and a receiving module, which are used to implement the sending and receiving functions in any of the above aspects and any possible implementation methods.

[0105] To facilitate understanding of the solutions provided in the embodiments of this application, some concepts involved in this application will be explained first.

[0106] 1. Carrier aggregation:

[0107] Carrier aggregation is a technology that integrates wireless channel resources within or between frequency bands to improve data transmission rates and reduce latency for users. In the field of communications, carrier aggregation technology can be used to combine spectrum resources in the same or different frequency bands to improve network resource utilization and enhance user experience. Specifically, carrier aggregation technology can combine two or more component carriers (CCs) together to support greater transmission bandwidth.

[0108] In carrier aggregation technology, the primary cell (PCell) is the cell where the terminal establishes an initial connection, or the cell where radio resource control (RRC) connection reconstruction is performed, or the primary cell designated during handover. The primary cell is responsible for RRC communication with the terminal. The carrier element corresponding to the primary cell is called the primary component carrier (PCC). Specifically, the downlink carrier of the primary cell can be called the downlink (DL) PCC, and the uplink carrier can be called the uplink (UL) PCC.

[0109] A secondary cell (SCell) is a cell added by the terminal during RRC reconfiguration to provide additional radio resources. There is no RRC communication between the secondary cell and the terminal. The carrier element corresponding to the secondary cell is called the secondary component carrier (SCC). Specifically, the downlink carrier of the secondary cell can be called a DL SCC, and the uplink carrier can be called a UL SCC.

[0110] For example, as shown in Figure 1, the communication system includes a base station 101 and a terminal 102. The cells covered by the base station 101 include cell A, cell B, and cell C. Cell A is the primary cell of the terminal 102, and the terminal 102 can perform RRC communication with cell A based on the primary carrier (i.e., the carrier unit corresponding to cell A). Cell B is a secondary cell of the terminal 102, and the terminal 102 can communicate with cell B based on secondary carrier 1 (i.e., the carrier unit corresponding to cell B). Cell C is another secondary cell of the terminal 102, and the terminal 102 can communicate with cell C based on secondary carrier 2 (i.e., the carrier unit corresponding to cell C).

[0111] In this example, one cell (or one carrier) can correspond to one frequency band. That is, in the communication system shown in Figure 1, the frequency bands corresponding to cells A, B, and C are F1, F2, and F3, respectively.

[0112] 2. Synchronization signal block (SSB):

[0113] The SSB consists of primary synchronization signals (PSS), secondary synchronization signals (SSS), and the physical broadcast channel (PBCH). It plays an important role in the 5G new radio (NR) network, providing stable and reliable communication services to terminals.

[0114] 3. System Information Block 1 (SIB1):

[0115] SIB1 is the first information block in the system information block, carrying the key information required for the terminal to access the cell.

[0116] 4. Channel State Information Reference Signal (CSI-RS):

[0117] CSI-RS is used to measure channel state information (CSI), including the rank indicator (RI), precoding matrix indicator (PMI), and channel quality indicator (CQI). This information helps the base station determine the current channel state, thereby optimizing the efficiency and reliability of data transmission.

[0118] 5. Tracking reference signal (TRS):

[0119] TRS is a reference signal used for tracking and measurement.

[0120] 6. Channel sounding reference signal (SRS):

[0121] SRS is used to estimate uplink channel frequency domain information and supports frequency-selective scheduling and downlink beamforming.

[0122] 7. Physical downlink shared channel (PDSCH):

[0123] PDSCH is the downlink physical channel for transmitting user data from the base station to the terminal.

[0124] 8. Physical uplink shared channel (PUSCH):

[0125] PUSCH is the uplink physical channel for transmitting user data from the terminal to the base station.

[0126] 9. Physical downlink control channel (PDCCH):

[0127] The PDCCH is mainly used to transmit downlink control information (DCI), including resource allocation, transmission format, and power control.

[0128] 10. Physical uplink control channel (PUCCH):

[0129] PUCCH is mainly used to transmit uplink control information (UCI).

[0130] 11. Physical Random Access Channel (PRACH):

[0131] PRACH is a channel used by a terminal in a communication system when initially accessing the network, to assist the terminal in establishing a connection with the network during initial access.

[0132] Based on the description of the above embodiments, when configuring the addition of a secondary cell, the base station manually configures and establishes a CA frequency point set. This CA frequency point set includes one or more frequency bands, and the cells corresponding to these frequency points are candidate secondary cells. After the terminal establishes an RRC connection with the primary cell, the primary cell combines the candidate secondary cells and the terminal's capabilities (including the CA capabilities supported by the terminal, such as the terminal supporting CA capabilities of two CCs) to determine the secondary cell that the terminal needs to add. Then, through an RRC reconfiguration message, the relevant information of the secondary cell that the terminal needs to add (including the configuration information of the secondary cell, such as the frequency band corresponding to the secondary cell, the signal location on the secondary cell, etc.) is sent to the terminal, so that the terminal can add the secondary cell according to the relevant information of the secondary cell.

[0133] Currently, there are two methods for adding secondary cells to a terminal: blind configuration and measurement-based configuration. For blind configuration, as shown in Figure 2, the base station can send an RRC reconfiguration message to the terminal, which includes information about the secondary cell. After receiving this RRC reconfiguration message, the terminal can complete the configuration of the secondary cell based on this information and then send an RRC reconfiguration complete message to the base station. For measurement-based configuration, the terminal not only needs to consider the information about the secondary cell but also needs to determine the signal quality of each cell included in the RRC reconfiguration message. Only when the signal quality of a cell meets certain conditions can that cell be configured as a secondary cell for the terminal.

[0134] In the first phase of the 5G standard (Release 15), NR defines two states for secondary cells: active and deactivated. When a secondary cell is active and has a PDCCH configured, the terminal needs to acquire the PDCCH of that secondary cell and transmit signals based on network configuration and uplink / downlink scheduling information. When a secondary cell is deactivated, the terminal does not need to transmit any uplink or downlink signals in that secondary cell. Once a secondary cell is added, its default state is deactivated.

[0135] As shown in Figure 3, the network can instruct the terminal to activate or deactivate the secondary cell via activation or deactivation of the Media Access Control (MAC) layer control element (MAC-CE) signaling. When the secondary cell is active, the terminal performs corresponding signal transmissions in that secondary cell. Additionally, the network can configure a deactivation timer for the terminal. When the deactivation timer expires, the terminal determines that the secondary cell's state has transitioned from active to deactivated.

[0136] In related technologies, when a terminal supports carrier aggregation capability and has corresponding RX filtering capability, the network side can configure multiple carriers for the terminal, so that the terminal can use these multiple carriers for data transmission.

[0137] When a terminal does not have RX capability that matches the number of carriers, i.e., in scenarios where the terminal capability is less than the network capability, the terminal can switch RX radio frequency channels to achieve the effect of switching transmission on multiple carriers.

[0138] Specifically, since the terminal only has the ability to receive downlink data on one carrier, in order to optimize the use of network spectrum resources, the terminal can switch between multiple carriers to achieve the effect of receiving downlink resources in every time slot.

[0139] For example, as shown in Figure 4, the network side has the n12 band and the n29 band. The terminal can receive downlink data in the first three downlink time slots and the last four downlink time slots in the n12 band, and receive downlink data in the middle three downlink time slots (including the fourth, fifth and sixth downlink time slots) in the n29 band.

[0140] In one scenario, when a terminal achieves efficient utilization of network resources through RX switching, it needs to periodically switch to another frequency band during measurement gaps to obtain reliable synchronization / measurement information transmitted on a carrier in another frequency band. During this time, the measurement signal transmitted on the other frequency band conflicts with the downlink signal on the source frequency band, thus affecting the link performance of the communication system.

[0141] In addition, given that there is only a 1MHz isolation bandwidth between the uplink of the n12 band and the downlink of the n29 band, and limited by the capabilities of the terminal duplexer, when the terminal switches to the n29 band to transmit data, the UE cannot send uplink information on the n12 band. Some uplink information on the n12 band is easily interrupted, thus affecting the transmission performance of the communication system.

[0142] As shown in Figure 5, the uplink frequency band of n12 includes 669MHz-716MHz, the downlink frequency band of n12 includes 729MHz-746MHz, and the downlink frequency band of n29 includes 717MHz-728MHz. When the terminal receives downlink information in the n29 frequency band, the terminal cannot receive downlink information in the n12 frequency band, nor can it send uplink information in the n12 frequency band.

[0143] In summary, since a terminal can only transmit data on one carrier at a time, and different carriers may interfere with each other, the data transmission performance of the communication system is reduced.

[0163] Optionally, the network device involved in this application (also referred to as access network device or access node, etc.) can be a device used to communicate with a terminal. This network device can be, for example, a network device in a 3GPP-related cellular system, such as a 4G, 5G mobile communication system, or a network device in a future-oriented evolution system.

[0165] In another possible scenario, multiple network devices collaborate to assist the terminal in achieving wireless access, with different network nodes each performing some of the base station's functions. For example, network devices can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU).

[0170] In one possible implementation, FIG7 is a schematic diagram of the composition of a communication device 700 provided in an embodiment of this application. The network device and terminal shown in FIG6 can both adopt the composition structure shown in FIG7, or include the components shown in FIG7; or, the network device, terminal and components (e.g., chips) in the terminal shown in FIG6 can all adopt the composition structure shown in FIG7, or include the components shown in FIG7. It is understood that the communication device 700 includes means of the necessary form, such as modules, units, elements, circuits or interfaces, to be appropriately configured together to implement this solution.

[0179] The communication method provided in the embodiments of this application will be described below with reference to Figures 8 to 10.

[0180] It should be noted that in the following embodiments of this application, the message names, parameter names, or information names between network elements are just examples. Other names may also be used in other embodiments. The communication method provided in this application does not specifically limit these names.

[0181] It is understood that in the embodiments of this application, each network element may execute some or all of the steps in the embodiments of this application. These steps or operations are merely examples, and the embodiments of this application may also execute other operations or variations thereof. Furthermore, the steps may be executed in different orders as presented in the embodiments of this application, and it is not necessary to execute all the operations in the embodiments of this application.

[0182] As shown in Figure 8, the communication method provided in this application embodiment includes S801-S803.

[0183] S801. The terminal determines the priority of the first information transmitted by the terminal and the network device on the first carrier, and the priority of the second information transmitted by the network device on the second carrier that the terminal needs to switch to.

[0184] The first carrier is the carrier used by the terminal when it is currently transmitting information with the network device. It can also be understood as the source carrier of the terminal. The first carrier is one of the multiple carriers corresponding to the terminal.

[0185] The first piece of information can be any data / signal that may be used in the interaction between the terminal and the network device. It can be system information (e.g., SSB signal, SIB1 signal), measurement information (e.g., CSI-RS signal, TRS signal, or SRS signal), control information (e.g., PDCCH signal, PUCCH signal), user information (e.g., PDSCH signal, PUSCH signal), or network information (e.g., PRACH signal), etc.

[0186] The priority of the first information is used to characterize the importance of the first information or the order in which the first information is transmitted. When the priority of the first information is higher, it means that the first information is more important, and the terminal and network device can transmit the first information first.

[0187] Optionally, the priority of the first piece of information can be an indicator that carries level information. A lower level can be defined as indicating higher priority, for example, level 1, level 2, and level 3 indicate decreasing priority in that order; or a higher level can be defined as indicating higher priority, for example, level 1, level 2, and level 3 indicate increasing priority in that order.

[0188] Optionally, the priority of the first piece of information can also be a numerical value, also known as the priority value. A higher priority value can be defined as indicating a higher priority; for example, a priority value of 0, 1, or 2 indicates an increasing priority. Alternatively, a lower priority value can be defined as indicating a higher priority; for example, a priority value of 0, 1, or 2 indicates a decreasing priority.

[0189] It should be understood that the second carrier is the carrier other than the first carrier among the multiple carriers corresponding to the terminal. This second carrier is the carrier that the terminal needs to switch to or is about to switch to, and can also be understood as the target carrier of the terminal.

[0190] The second piece of information can be any data / signals that may be used in the interaction between the terminal and the network device. This could be measurement information (e.g., CSI-RS signal) or user information (e.g., PDSCH signal), etc.

[0191] It is understandable that the explanation of the priority of the second information is the same as or similar to the explanation of the priority of the first information, and will not be repeated here.

[0192] Optionally, the transmission direction of the first and second information can be uplink transmission, i.e., the terminal sends the first and second information to the network device. Alternatively, the transmission direction of the first and second information can be downlink transmission, i.e., the network device sends the first and second information to the terminal. This application embodiment does not specifically limit the transmission direction of the first and second information.

[0193] In this embodiment of the application, when the terminal needs to transmit second information, the priority of the first information and the priority of the second information can be determined. The terminal needing to transmit second information can be understood as the current time being the start time for the transmission of the second information.

[0194] In one scenario, when the first information has been completely transmitted, it means that there is no remaining first information that the terminal and network device need to transmit on the first carrier. At this time, the terminal can determine the priority of the first information and the priority of the second information, thereby determining whether the terminal should prioritize transmitting the second information or prioritize transmitting the first information (specifically, waiting to execute the next round of first information transmission).

[0195] In another scenario, if the first information is not fully transmitted, it indicates that some of the first information has not been transmitted. In this case, the terminal can determine the priority of the first information and the priority of the second information, thereby determining whether the terminal should prioritize transmitting the second information or prioritize transmitting the missing portion of the first information.

[0196] Based on this situation, the terminal determines the priority of the first information transmitted by the terminal and the network device on the first carrier, and the priority of the second information transmitted by the terminal and the network device on the second carrier that the terminal needs to switch to, which may specifically include S8011.

[0197] S8011. When the terminal needs to transmit second information on the second carrier, and the first information has not been transmitted on the first carrier, the terminal determines the priority of the first information and the priority of the second information.

[0198] It should be understood that when a terminal needs to transmit second information on a second carrier, and the first information has not been fully transmitted on the first carrier, it means that the terminal needs to transmit both the first and second information on the first and second carriers. Since a terminal can only transmit data on one carrier at a time, it needs to determine the priority of the first and second information to decide whether to prioritize transmitting the second information or the untransmitted portion of the first information. Furthermore, since some of the first information has already been transmitted, even if the priority of the second information is the same as that of the first information, the terminal can still prioritize transmitting the untransmitted second information, avoiding information loss between the terminal and network equipment and ensuring that more important information is transmitted.

[0199] In some embodiments, different types of information may have different priorities. Based on this, the terminal determines the priority of the first information transmitted on the first carrier by the terminal and the network device, which can be achieved through the following S8012-S8013.

[0200] S8012, The type of first information acquired by the terminal.

[0201] S8013. The terminal determines the priority of the first information based on the type of the first information.

[0202] In this embodiment, different types of information often imply different levels of importance. For example, control plane information is more important than user plane information, and therefore has a higher priority. Thus, the terminal can accurately determine the priority of the first information based on its type.

[0203] In one optional implementation, the type of the first information mentioned above includes at least one of the following: a type of periodic information, a type of user information, a type of non-periodic information, a type of on-demand triggered information, a type of control information, or a type of network access information.

[0204] Periodic information refers to information with a fixed transmission period. This fixed transmission period can be predefined by the protocol between the terminal and the network device or configured by the network device through RRC signaling. Therefore, periodic information has a lower priority.

[0205] User information is user plane information in the network, and the type of user information can also be understood as user plane type. Because the network allocates more resources to user information, and user information has lower latency requirements, its priority is also lower.

[0206] Non-periodic information refers to information with a non-fixed transmission period, which is triggered on demand by network devices. In other words, both non-periodic information and the aforementioned on-demand triggered information are triggered on demand / actively by network devices, therefore, non-periodic information and on-demand triggered information have higher priority.

[0207] Control information refers to control plane information within the network, and its type is also understood as control plane type. Because control information carries network scheduling commands, it has a high priority. Network access information is crucial for terminal access to the network, and therefore also has a high priority.

[0208] In this implementation, different types of information often imply varying degrees of importance. For example, regarding periodic and aperiodic information, the fixed transmission period of periodic information is predefined or configured via RRC signaling, while aperiodic information is triggered on demand / actively by network devices. Aperiodic information is more important than periodic information, and therefore has a higher priority. Thus, for the first piece of information, the terminal can accurately determine its priority based on the different types it includes.

[0209] In one implementation of this application embodiment, the terminal determines the priority of the first information according to the type of the first information, specifically including S8013a-S8013b.

[0210] S8013a. When the type of the first information is periodic information or user information, the terminal determines the priority of the first information as the first priority.

[0211] S8013b: When the type of the first information is a non-periodic information type, an on-demand trigger information type, a control information type, or a network access information type, the terminal determines the priority of the first information as the second priority.

[0212] Among them, the second priority is higher than the first priority.

[0213] It should be understood that explanations of periodic information, user information, non-periodic information, on-demand triggered information, control information, and network access information can be found in the description in S8013 above, and will not be repeated here.

[0214] In this embodiment, when the type of the first information is periodic information, it indicates that the first information is predefined or configured, and the terminal can determine that the first information has a low priority, specifically the first priority. When the type of the first information is user information, it indicates that the first information has a low latency requirement, and the terminal can also determine that the first information has a low priority. However, when the type of the first information is non-periodic information or on-demand triggered information, it indicates that the first information is triggered on-demand / actively by the network device, and the terminal can determine that the first information has a high priority, specifically the second priority. When the type of the first information is control information, it indicates that the first information carries network scheduling commands, and the terminal can also determine that the first information has a high priority. When the type of the first information is network access information, it indicates that the first information is key information for the terminal to access the network, and the terminal can determine that the first information has a high priority. That is, based on the different types of the first information, the terminal can accurately and effectively determine the priority of the first information.

[0215] It is understandable that the specific implementation of the terminal determining the priority of the second information is the same as or similar to the specific implementation of the terminal determining the priority of the first information, and will not be elaborated here.

[0216] In one implementation of this application, after the terminal obtains the type of the first information, the communication method provided in this application may further include steps A-B.

[0217] Step A: When the type of the first information is periodic information or user information, the terminal determines that the priority of the second information is higher than or equal to the priority of the first information.

[0218] Step B: When the type of the first information is non-periodic information, on-demand triggered information, control information, or network access information, the terminal determines that the priority of the second information is lower than the priority of the first information.

[0219] In this implementation, when the first information is of periodic type, it indicates that the first information is predefined or configured and has a low priority. The terminal can determine that the priority of the second information is higher than or equal to the priority of the first information, meaning the second information has a higher priority. When the first information is of user information type, it indicates that the first information has low latency requirements and also has a low priority. The terminal can also determine that the priority of the second information is higher than or equal to the priority of the first information. When the first information is of non-periodic type or on-demand triggered type, it indicates that the first information is triggered on-demand / actively by the network device and has a high priority. The terminal can determine that the priority of the second information is lower than the priority of the first information, meaning the second information has a lower priority. When the first information is of control information type, it indicates that the first information carries network scheduling commands, and the terminal can also determine that the priority of the second information is lower than the priority of the first information. When the first information is of network access information type, it indicates that the first information is key information for the terminal to access the network, and the terminal can also determine that the priority of the second information is lower than the priority of the first information. By using different types of first information, the terminal can determine the priority of the second information relative to the first information, thereby ensuring that information of higher importance is transmitted first.

[0220] In one implementation of this application, the aforementioned periodic information is any one of the following information with a fixed transmission period: SSB signal, SIB1 signal, CSI-RS signal, TRS signal, or SRS signal.

[0221] It should be understood that since the fixed transmission periods of SSB, SIB1, CSI-RS, TRS, and SRS signals are predefined by the protocol between the terminal and the network device or configured via RRC signaling, these signals have lower priority. When these signals are being transmitted on the first carrier, the terminal can switch from the first carrier to the second carrier to transmit the second information with the network device on the second carrier, thus ensuring that information of higher importance is transmitted first.

[0222] In this embodiment of the application, the SSB signal and SIB1 signal with a fixed transmission period can also be understood as periodic common signals.

[0223] In another implementation of this application, the aforementioned user information is a PDSCH signal or a PUSCH signal.

[0224] It should be understood that since the PDSCH signal and PUSCH signal are user information transmitted from the base station to the terminal and from the terminal to the base station, respectively, and this user information has low latency requirements, its priority is low. When this user information is being transmitted on the first carrier, the terminal can switch from the first carrier to the second carrier to transmit the second information with the network equipment on the second carrier, thus ensuring the effective transmission of more important information.

[0225] In one alternative implementation, the aforementioned aperiodic information is any one of the following information with a non-fixed transmission period: CSI-RS signal, TRS signal, or SRS signal.

[0226] Optionally, the CSI-RS signal, TRS signal, and SRS signal with non-fixed transmission period can be information triggered by the network device through MAC-CE signaling or DCI.

[0227] In this implementation, since the CSI-RS, TRS, and SRS signals, which have non-fixed transmission periods, are information triggered on demand / actively by the network device, these signals have a higher priority. When these signals are being transmitted on the first carrier, the terminal does not need to switch from the first carrier to the second carrier, but continues to transmit these high-priority signals with the network device on the first carrier, thereby ensuring the priority transmission of important, on-demand triggered information.

[0228] In another alternative implementation, the aforementioned on-demand triggering information is any one of the following on-demand triggering information: the SSB signal or the SIB1 signal.

[0229] In this embodiment of the application, the SSB signal and SIB1 signal triggered on demand can also be understood as on-demand (OD) common signals.

[0230] Optionally, the SSB and SIB1 signals triggered on demand can also be information triggered by network devices via MAC-CE signaling or DCI.

[0231] In this implementation, since the SSB and SIB1 signals triggered on demand are information triggered / actively by the network device, their priority is relatively high. When this information is being transmitted on the first carrier, the terminal does not need to switch from the first carrier to the second carrier, but continues to transmit this high-priority information with the network device on the first carrier, thereby ensuring that the more important, on-demand triggered information is transmitted first.

[0232] In another alternative implementation, the aforementioned control information is either a PDCCH signal or a PUCCH signal.

[0233] It should be understood that since the PDCCH and PUCCH signals are control information transmitted from the base station to the terminal and from the terminal to the base station, respectively, and the control information carries network scheduling commands, it is of high importance to the terminal. Therefore, this control information has a high priority. When this control information is being transmitted on the first carrier, the terminal does not need to switch from the first carrier to the second carrier, but continues to transmit this high-priority / high-importance control information with the network equipment on the first carrier, which can ensure the effective transmission of the high-importance information.

[0234] Optionally, the aforementioned network access information is a PRACH signal.

[0235] It should be understood that because the PRACH signal is used to assist the terminal in establishing a connection with the network during initial access, it is crucial information for the terminal's network access and therefore has a high priority. When a PRACH signal is being transmitted on the first carrier, the terminal does not need to switch from the first carrier to the second carrier; instead, it continues to transmit higher-priority / more important PRACH signals with the network device on the first carrier. This ensures the communication connection between the terminal and the network and improves the terminal's communication stability.

[0236] S802. The terminal determines to switch from the first carrier to the second carrier based on the priority of the first information and the priority of the second information.

[0237] In one scenario, when the priority of the second piece of information is higher than that of the first piece of information, it indicates that the second piece of information has a higher priority, and the terminal can prioritize transmitting the second piece of information. In this case, the terminal determines to switch from the first carrier to the second carrier, ensuring that the terminal prioritizes the transmission of information with higher priority / importance, thus improving the reliability of the communication system.

[0238] In another scenario, when the priority of the second information is equal to the priority of the first information, it means that the priority of the second information is the same as that of the first information. Since the terminal needs to switch to the second carrier to transmit the second information with the network device, the terminal can also prioritize transmitting the second information. In this case, the terminal determines to switch from the first carrier to the second carrier and can prioritize transmitting the information after the carrier switch (i.e., the second information), which can improve the effectiveness of the carrier switch.

[0239] Optionally, when the priority of the second information is lower than that of the first information, it indicates that the second information has a lower priority, and the terminal can prioritize transmitting the first information. In this case, the terminal determines that its data transmission carrier remains unchanged, stops switching from the first carrier to the second carrier, and continues to transmit the first information with the network device on the first carrier, thus ensuring the effective transmission of information with higher priority / importance.

[0240] S803, The terminal transmits second information with the network device on the second carrier.

[0241] In this embodiment, regarding the first information transmitted by the terminal and network device on the first carrier, and the second information that the terminal needs to switch to on the second carrier to transmit with the network device, the terminal can determine the priority of the first information and the priority of the second information. Based on the priority of the first information and the priority of the second information, the terminal can determine to prioritize the transmission of the second information. That is, the terminal can determine to switch from the first carrier to the second carrier, and thus transmit the second information with the network device on the second carrier. This effectively determines that data should be transmitted on the second carrier to be switched at that moment, improving the data transmission performance of the communication system.

[0242] In one implementation of this application, the second information is information used to measure the channel state.

[0243] In this implementation, after the terminal switches from the first carrier to the second carrier, it indicates that the priority of the information used to measure the channel state (i.e., the second information) is higher than or equal to the priority of the first information. In other words, the information used to measure the channel state has a higher priority / importance. The terminal can preferentially transmit the information used to measure the channel state on the second carrier, so that the terminal can preferentially perform the channel state measurement process to ensure the stability of the channel state.

[0244] Optionally, the information used to measure the channel state is a CSI-RS signal.

[0245] It should be understood that after the terminal switches from the first carrier to the second carrier, it indicates that the priority of the CSI-RS signal is higher than or equal to the priority of the first information. That is, the CSI-RS signal has a higher priority / importance. The terminal can preferentially transmit the CSI-RS signal on the second carrier, thereby enabling the terminal to preferentially perform downlink channel state measurement operations, so as to prioritize the downlink synchronization / measurement process and improve the stability of the communication system.

[0246] In one alternative implementation, the frequency band corresponding to the first carrier is different from the frequency band corresponding to the second carrier.

[0247] It should be understood that one carrier can correspond to one or more frequency bands, and one frequency band corresponds to one carrier. The first information transmitted by the terminal and network device on the first carrier specifically includes the transmission of the first information by the terminal and network device on the frequency band corresponding to the first carrier; the transmission of the second information by the terminal and network device on the second carrier specifically includes the transmission of the second information by the terminal and network device on the frequency band corresponding to the second carrier.

[0248] In this embodiment, the frequency band corresponding to the first carrier can be understood as the source frequency band of the terminal, and the frequency band corresponding to the second carrier can be understood as the target frequency band of the terminal. Switching from the first carrier to the second carrier can also be understood as switching from the source frequency band to the target frequency band.

[0249] In this implementation, since different carriers correspond to different frequency bands, the terminal switches from the frequency band corresponding to the first carrier to the frequency band corresponding to the second carrier by switching from the first carrier to the second carrier. Thus, the terminal can transmit data through the corresponding frequency band, ensuring the effective transmission of important data.

[0250] For example, the frequency band corresponding to the first carrier can be the n12 frequency band, and the frequency band corresponding to the second carrier can be the n29 frequency band. The frequency bands corresponding to the first carrier and the second carrier can also be any combination of the following frequency bands: 1.8 GHz, 2.1 GHz, 2.6 GHz, 3.5 GHz, and 4.9 GHz.

[0251] Optionally, when the terminal is transmitting second information with the network device on the second carrier, the terminal may pause / interrupt the transmission of the first information. After the transmission of the second information is completed, the terminal may switch from the second carrier to the first carrier and continue transmitting the first information with the network device on the first carrier.

[0252] For example, as shown in Figure 9, assume that carrier a is the first carrier and carrier b is the second carrier.

[0253] The terminal first transmits first information with the network device on carrier a. Then, the terminal switches from carrier a to carrier b at times t1, t3, and t5, and transmits second information with the network device on carrier b during the time intervals formed by t1 and t2, t3 and t4, and t5 and t6.

[0254] Furthermore, the terminal switches from carrier b to carrier a at times t2, t4, and t5, respectively, and transmits the first information with the network device on carrier a during the time intervals formed by t2 and t3, t4 and t5, and t6 and t7.

[0255] It should be understood that the terminal interrupts the transmission of the first information during the time intervals formed by t1 and t2, t3 and t4, and t5 and t6.

[0256] Assuming the second information mentioned above is a CSI-RS signal, the following uses different types of first information as examples to illustrate the process by which the terminal performs different operations based on the communication method provided in the embodiments of this application.

[0257] Table 1

[0258] As shown in Table 1, if the first information is an SSB signal, SIB1 signal, CSI-RS signal, TRS signal, or SRS signal with a fixed transmission period; or if the first information is a PDSCH signal or PUSCH signal, then the terminal switches from the first carrier to the second carrier and transmits the CSI-RS signal with the network device on the second carrier. If the first information is a CSI-RS signal, TRS signal, or SRS signal with a non-fixed transmission period; or if the first information is an SSB signal or SIB1 signal triggered on demand; or if the first information is a PDCCH signal, PUCCH signal, or PRACH signal, then the terminal continues to transmit the first information on the first carrier, i.e., no carrier switching operation is performed.

[0259] In some embodiments, whether the terminal switches from the first carrier to the second carrier can be determined by the network device. The terminal switches from the first carrier to the second carrier by receiving relevant instructions sent by the network device. Based on this, as shown in FIG10, the communication method provided in this application embodiment includes S1001-S1004.

[0260] S1001, The network device determines the priority of the first information transmitted by the terminal and the network device on the first carrier, and the priority of the second information transmitted by the network device on the second carrier that the terminal needs to switch to.

[0261] It should be understood that the explanation of S1001 is the same as or similar to the explanation of S801 in the above embodiments. For the explanation of S1001, please refer to S801 in the above embodiments, and it will not be repeated here.

[0262] In one implementation of this application, the network device determines the priority of the first information transmitted by the terminal and the network device on the first carrier, and the priority of the second information transmitted by the terminal and the network device on the second carrier that the terminal needs to switch to, specifically including S10011.

[0263] S10011 When the terminal needs to transmit second information on the second carrier, and the first information has not been transmitted on the first carrier, the network device determines the priority of the first information and the priority of the second information.

[0264] It should be understood that the explanation of S10011 is the same as or similar to the explanation of S8011 in the above embodiments. For the explanation of S10011, please refer to S8011 in the above embodiments, which will not be repeated here.

[0265] In another implementation of the embodiments of this application, the network device determines the priority of the first information transmitted by the terminal and the network device on the first carrier, specifically including S10012-S10013.

[0266] S10012, The type of first information obtained by the network device.

[0267] S10013. The network device determines the priority of the first information based on the type of the first information.

[0268] Optionally, the type of the first information includes at least one of the following: a type of periodic information, a type of user information, a type of non-periodic information, a type of on-demand triggered information, a type of control information, or a type of network access information.

[0269] It should be understood that the explanations of S10012-S10013 are the same as or similar to the explanations of S8012-S8013 in the above embodiments. For explanations of S10012-S10013, please refer to S8012-S8013 in the above embodiments, and will not be repeated here.

[0270] In one implementation of this application embodiment, the network device determines the priority of the first information according to the type of the first information, specifically including S10013a-S10013b.

[0271] S10013a. When the type of the first information is periodic information or user information, the terminal determines the priority of the first information as the first priority.

[0272] S10013b: When the type of the first information is non-periodic information, on-demand triggering information, control information, or network access information, the terminal determines the priority of the first information as the second priority.

[0273] Among them, the second priority is higher than the first priority.

[0274] In one implementation of this application embodiment, after the network device obtains the type of the first information, the communication method provided in this application embodiment may further include steps C-D.

[0275] Step C: When the type of the first information is periodic information or user information, the network device determines that the priority of the second information is higher than or equal to the priority of the first information.

[0276] Step D: When the type of the first information is non-periodic information, on-demand triggered information, control information, or network access information, the network device determines that the priority of the second information is lower than the priority of the first information.

[0277] It should be understood that the explanations of steps C-D are the same as or similar to those of steps A-B in the above embodiments. For explanations of steps C-D, please refer to steps A-B in the above embodiments, and they will not be repeated here.

[0278] In one implementation of this application, the aforementioned periodic information is any one of the following information with a fixed transmission period: SSB signal, SIB1 signal, CSI-RS signal, TRS signal, or SRS signal.

[0279] In another implementation of this application, the aforementioned user information is a PDSCH signal or a PUSCH signal.

[0280] In one alternative implementation, the aforementioned aperiodic information is any one of the following information with a non-fixed transmission period: CSI-RS signal, TRS signal, or SRS signal.

[0281] Optionally, the above-mentioned on-demand triggering information is any one of the following on-demand triggering information: SSB signal or SIB1 signal.

[0282] In another alternative implementation, the control information mentioned above is either a PDCCH signal or a PUCCH signal.

[0283] In another alternative implementation, the aforementioned network access information is the PRACH signal.

[0284] It should be understood that the explanations of S10013a-S10013b are the same as or similar to the explanations of S8013a-S8013b in the above embodiments. For explanations of S10013a-S10013b, please refer to S8013a-S8013b in the above embodiments, and will not be repeated here.

[0285] S1002, the network device sends a first instruction to the terminal according to the priority of the first information and the priority of the second information. Correspondingly, the terminal receives the first instruction from the network device.

[0286] The first instruction is used to instruct the terminal to switch from the first carrier to the second carrier.

[0287] In one scenario, when the priority of the second piece of information is higher than that of the first piece of information, it indicates that the second piece of information has a higher priority, and the terminal can prioritize transmitting the second piece of information. In this case, the network device can send a first instruction to the terminal to instruct the terminal to switch from the first carrier to the second carrier, ensuring that the terminal prioritizes the transmission of higher-priority data and improving the reliability of data transmission.

[0288] In another scenario, when the priority of the second information is equal to the priority of the first information, it means that the priority of the second information is the same as that of the first information. Since the terminal needs to switch to the second carrier to transmit the second information with the network device, the terminal can also prioritize transmitting the second information. In this case, the network device can also send a first instruction to the terminal to instruct the terminal to switch from the first carrier to the second carrier, so that the data after the carrier switch (i.e., the second information) can be transmitted first, which can improve the effectiveness of the carrier switch.

[0289] Optionally, when the priority of the second information is lower than that of the first information, it indicates that the second information has a lower priority, and the terminal can prioritize transmitting the first information. In this case, the network device can determine that the terminal's data transmission carrier remains unchanged, that is, the network device does not send the first instruction to the terminal, and the terminal continues to transmit the first information with the network device on the first carrier.

[0290] S1003. The terminal switches from the first carrier to the second carrier based on the first instruction and the second instruction.

[0291] The second instruction is an instruction that instructs the terminal to transmit the aforementioned first information.

[0292] It should be understood that network devices can also send a second instruction to the terminal to instruct the terminal to transmit the first information.

[0293] In some embodiments, the terminal switches from the first carrier to the second carrier based on the first instruction and the second instruction, which may specifically include S10031-S10032.

[0294] S10031. When the transmission direction of the first information is uplink transmission, the terminal determines the configuration type of the first instruction and the configuration type of the second instruction.

[0295] S10032. The terminal switches from the first carrier to the second carrier based on the configuration type of the first instruction and / or the configuration type of the second instruction.

[0296] It should be understood that when the transmission direction of the first information is uplink, it means that the first information is information sent by the terminal to the network device. Since the terminal may not expect to receive downlink transmission instructions from the network device while simultaneously sending information to it, the terminal needs to determine the configuration type of the first instruction and the configuration type of the second instruction. Based on the configuration types of the first and / or second instructions, their priority / importance can be determined, allowing the terminal to execute operations related to the higher-priority / important first instruction, such as switching from the first carrier to the second carrier, thus ensuring the effective transmission of more important data.

[0297] Optionally, when the transmission direction of the first information is downlink transmission, it indicates that the first information is information sent by the network device to the terminal. In this case, the first instruction received by the terminal has little impact on the first information, and the terminal can directly perform related operations according to the terminal's first instruction, specifically switching from the first carrier to the second carrier.

[0298] In one alternative implementation, the above configuration type can be either static or dynamic.

[0299] It should be understood that static configuration is a pre-configured configuration type for network devices, while dynamic configuration is a configuration type for network devices that are configured on demand or proactively.

[0300] In this implementation, different configuration types often imply varying degrees of importance for instructions. For example, regarding a dynamically configured first instruction and a statically configured second instruction, the dynamically configured first instruction is more important than the statically configured second instruction, and therefore has a higher priority. Thus, for both the first and second instructions, the terminal can determine their importance / priority based on their specific configuration types, and switch from the first carrier to the second carrier according to the higher-priority first instruction, ensuring that information with higher priority is transmitted first.

[0301] Optionally, the above static configuration may specifically include semi-static RRC configuration, and the above dynamic configuration may specifically include dynamic DCI indication.

[0302] In one implementation of this application, the terminal switches from the first carrier to the second carrier based on the configuration type of the first instruction and / or the configuration type of the second instruction, which may specifically include S10032a.

[0303] S10032a When the configuration type of the second instruction is static configuration, the terminal switches from the first carrier to the second carrier.

[0304] It should be understood that when the configuration type of the second instruction is static configuration, it means that the second instruction is pre-configured by the network device. In this case, regardless of whether the configuration type of the first instruction is static or dynamic configuration, the priority of the second instruction is lower than that of the first instruction. Thus, the terminal can switch from the first carrier to the second carrier based on the first instruction, ensuring that the second information with higher priority / importance is transmitted first.

[0305] In one implementation of this application, the terminal switches from the first carrier to the second carrier based on the configuration type of the first instruction and / or the configuration type of the second instruction, which may specifically include S10032b-S10032c.

[0306] S10032b: When the configuration type of the second instruction is dynamic configuration and the configuration type of the first instruction is dynamic configuration, obtain the first time point and the second time point.

[0307] The first moment is the moment when the terminal receives the first instruction, and the second moment is the moment when the terminal receives the second instruction.

[0308] S10032c: When the first time point is before the second time point, the terminal switches from the first carrier to the second carrier.

[0309] In this embodiment, since dynamic configuration is performed on demand / actively by the network device, when both the configuration type of the second instruction and the configuration type of the first instruction are dynamic configurations, it indicates that the priority of both the second and first instructions is higher. The terminal can prioritize the first instruction received / detected between the two instructions and perform relevant operations accordingly. At this time, the terminal can obtain the times at which it receives the two instructions, namely the first moment and the second moment. When the first moment is before the second moment, it indicates that the terminal receives the first instruction first, and thus the terminal can execute the instruction in the first instruction, i.e., switch from the first carrier to the second carrier. This ensures that the terminal executes the network device's dynamically configured instructions in chronological order, improving the reliability of the communication system.

[0310] In one alternative implementation, when the first moment occurs after the second moment, it indicates that the terminal has received the second instruction first. At this time, the terminal can execute the instructions in the second instruction, i.e., transmit the first information. Thus, the terminal determines that its data transmission carrier remains unchanged, and the terminal does not perform a carrier switching operation, i.e., it does not switch from the first carrier to the second carrier, and continues to transmit the first information with the network device on the first carrier.

[0311] In another optional implementation, when the configuration type of the second instruction is dynamic configuration and the configuration type of the first instruction is static configuration, since dynamic configuration is a configuration type triggered on demand / actively by the network device, while static configuration is a pre-configured configuration type of the network device, the priority of the dynamic configuration instruction is higher than that of the static configuration instruction. That is, the terminal can determine that the priority of the second instruction is higher than that of the first instruction. In this case, the terminal can also execute the instruction in the second instruction, i.e., transmit the first information. Thus, the terminal determines that its data transmission carrier remains unchanged, and the terminal does not perform a carrier switching operation, i.e., it does not switch from the first carrier to the second carrier, and continues to transmit the first information with the network device on the first carrier.

[0312] S1004. The terminal transmits second information to the network device on the second carrier.

[0313] It should be understood that the explanation of S1004 is the same as or similar to the explanation of S803 in the above embodiments. For the explanation of S1004, please refer to S803 in the above embodiments, and it will not be repeated here.

[0314] In this embodiment, regarding the first information transmitted by the terminal and network device on the first carrier, and the second information that the terminal needs to switch to for transmission on the second carrier, the network device can determine the priority of the first information and the priority of the second information. Based on these priorities, the network device can prioritize the transmission of the second information; that is, the network device can send a first instruction to the terminal to instruct it to switch from the first carrier to the second carrier. This effectively determines that the terminal should transmit data on the second carrier at the moment of switching, improving the data transmission performance of the communication system.

[0315] Furthermore, after receiving the first instruction from the network device, the terminal can switch from the first carrier to the second carrier based on the first and second instructions, thereby transmitting second information with the network device on the second carrier. This ensures that more important data can be effectively transmitted and improves the stability of the communication system.

[0316] Assuming the transmission direction of the first information is uplink transmission, the following first and second instructions of different configuration types are examples illustrating the process of different operations performed by the terminal based on the communication method provided in the embodiments of this application.

[0317] Table 2

[0318] As shown in Table 2, if the configuration type of the second instruction is static, regardless of whether the configuration type of the first instruction is static or dynamic, the terminal can switch from the first carrier to the second carrier and transmit the second information with the network device on the second carrier. If the configuration type of the second instruction is dynamic and the configuration type of the first instruction is static, the terminal continues to transmit the first information on the first carrier, i.e., no carrier switching operation is performed. If the configuration type of the second instruction is dynamic and the configuration type of the first instruction is dynamic, the terminal takes the first instruction received as the standard. Specifically, if the first instruction received by the terminal is the first instruction, the terminal switches from the first carrier to the second carrier and transmits the second information with the network device on the second carrier; if the first instruction received by the terminal is the second instruction, the terminal continues to transmit the first information on the first carrier and no carrier switching operation is performed.
