Description

Communication methods and devices

[0001] This application claims priority to Chinese patent application filed on March 27, 2025, with application number 202510380502.X and entitled "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 cellular communication systems, terminal devices communicate with network devices based on cells. As a terminal device moves, it moves from the signal coverage area of ​​one cell to the signal coverage area of ​​another. For that terminal device, the signal strength of the other cell is stronger, and the network device can instruct the terminal device to switch to the other cell. After the terminal device switches to the other cell, it transmits data with the network device using the transmission parameters of the other cell.

[0004] Therefore, terminal devices need to perform signal measurements on candidate cells and report them. However, how the terminal device should initiate signal measurements on candidate cells and report them is a question worth considering. Summary of the Invention

[0005] This application provides a communication method and apparatus for measuring the reference signal of a first candidate cell and reporting the measurement results. For the receiving device, the measurement results can be used to determine whether to instruct the terminal device to switch from the serving cell to the first candidate cell. This facilitates the selection of a suitable cell for the terminal device and helps ensure communication quality. Alternatively, in scenarios where the terminal device has already switched to or is about to switch to the first candidate cell, the receiving device can determine the transmission parameters of the first candidate cell based on the measurement results. The receiving device can then transmit data with the terminal device using these transmission parameters. This helps ensure communication quality between the terminal device and network devices within the first candidate cell.

[0006] This application provides a communication method, which is applied to a first communication device, which is a terminal device or a device applied to a terminal device. For example, the terminal device may include a chip, chip system, module, processing unit, control unit, or circuit, etc., without specific limitations in this application. It should be noted that, in this application, when referring to a terminal device, it can refer to the terminal device itself, or it can be replaced by a chip, functional module, or integrated circuit in the terminal device that performs the method provided in this application, without specific limitations in this application. The method includes: the first communication device receiving first information, the first information indicating: reporting a measurement result corresponding to a first reporting configuration. Then, the first communication device sends the measurement result corresponding to the first reporting configuration, wherein the measurement result is a measurement result of a reference signal corresponding to one or more measurement resources associated with the first reporting configuration, and the one or more measurement resources are measurement resources corresponding to a first candidate cell.

[0007] In the above technical solution, the first communication device receives first information. This first information is used to instruct the reporting of measurement results corresponding to the first reporting configuration. The first communication device sends the measurement results corresponding to the first reporting configuration. These measurement results are the measurement results of reference signals corresponding to one or more measurement resources associated with the first reporting configuration. These one or more measurement resources are the measurement resources corresponding to the first candidate cell. This enables the first communication device to measure and report the reference signals of the first candidate cell. For the receiving device, the receiving device can determine whether to instruct the terminal device to switch from the serving cell to the first candidate cell based on the measurement results. This is beneficial for selecting a suitable cell for the terminal device and for ensuring communication quality. For example, the measurement results include the signal quality of the first candidate cell, and the network device can determine whether to instruct the terminal device to switch to the first candidate cell based on the signal quality of the first candidate cell. For example, if the signal quality of the first candidate cell is better than the signal quality of the serving cell, the network device can instruct the terminal device to switch to the first candidate cell. Alternatively, in a scenario where the terminal device has already switched to or will switch to the first candidate cell, the receiving device can determine the transmission parameters of the first candidate cell based on the measurement results. The receiving device can then transmit data with the terminal device using the transmission parameters of the first candidate cell. This approach helps ensure communication quality between the terminal device and network device in the first candidate cell. Furthermore, before switching to the first candidate cell, the terminal device measures the reference signal of the first candidate cell to obtain measurement results. These measurement results include channel state information. The terminal device then reports the measurement results. When the terminal device switches to the first candidate cell, the network device can transmit data with the terminal device based on the channel state information indicated by the measurement results. The network device does not need to obtain channel state information through the traditional channel measurement process. The traditional channel measurement process causes a delay in obtaining channel state information. During this delay, the network device lacks the channel state information of the first candidate cell, making efficient data transmission for the terminal device impossible and affecting the data transmission performance between the terminal device and the network device. The technical solution of this application avoids this problem.

[0008] Based on the first aspect, in one possible implementation, the measurement results are carried on a first uplink channel, which is either the uplink channel of the serving cell or the uplink channel of the first candidate cell. Two methods for reporting the above measurement results are provided, facilitating the terminal device to feed back the measurement results to the network device.

[0009] Based on the first aspect, in one possible implementation, the first uplink channel is determined according to the reporting amount configured in the first reporting configuration. In this implementation, the first communication device determines the first uplink channel for reporting measurement results based on the reporting amount configured in the first reporting configuration. This ensures that the terminal device correctly transmits the measurement results, facilitating the network device's reception of the measurement results.

[0010] Based on the first aspect, in one possible implementation, when the reporting quantity configured in the first reporting configuration includes the reference signal received power (RSRP), the first uplink channel is the uplink channel of the serving cell. In this implementation, if the reporting quantity includes RSRP, which is used to characterize the signal quality of the reference signal, then the first communication device can report the measurement results through the uplink channel of the serving cell. It is understood that if the reporting quantity includes RSRP, it indicates that the terminal device is in a beam management process, that is, the network device selects a candidate cell for the terminal device based on the RSRPs of each candidate cell. In other words, the terminal device is still within the serving cell, therefore the terminal device can send the measurement results through the uplink channel of the serving cell.

[0011] Based on the first aspect, in one possible implementation, when the reporting quantity configured in the first reporting configuration includes parameters characterizing the signal quality of the reference signal, the first uplink channel is the uplink channel of the serving cell. In this implementation, if the reporting quantity includes parameters characterizing the signal quality of the reference signal, it can be understood that the terminal device is in a beam management process, and the network device selects a candidate cell for the terminal device during this beam management process. That is, the terminal device is still within the serving cell, and therefore the terminal device can send the measurement result through the uplink channel of the serving cell.

[0012] Based on the first aspect, in one possible implementation, the parameter used to characterize the signal quality of the reference signal includes at least one of the following: RSRP, or signal to interference plus noise ratio (SINR).

[0013] Based on the first aspect, in one possible implementation, the first communication device sends the measurement result corresponding to the first reporting configuration, including: the first communication device sends the measurement result through a first uplink channel in a first time domain unit, where the first time domain unit is the time domain unit for receiving the first information plus the time domain unit corresponding to the time offset. This implementation defines the specific time for the first communication device to report the measurement result, ensuring that the terminal device correctly sends the measurement result, thus facilitating the network device's reception of the measurement result.

[0014] Based on the first aspect, in one possible implementation, when the reporting quantity configured in the first reporting configuration includes at least one of the channel quality indicator (CQI), rank indicator (RI), and precoding matrix indicator (PMI), the first uplink channel is the uplink channel of the first candidate cell. In this implementation, if the reporting quantity includes parameters characterizing the downlink channel state, it can be understood that the terminal device has already switched to or will switch to the first candidate cell. Therefore, after the terminal device switches to the first candidate cell, it can send the measurement result through the uplink channel of the first candidate cell. Then, the network device can transmit with the terminal device based on the channel state information indicated by the measurement result. The network device does not need to obtain channel state information through the traditional channel measurement process. The traditional channel measurement process causes a delay in obtaining channel state information. During this delay, the network device does not have the channel state information of the first candidate cell, and cannot perform efficient data transmission for the terminal device, affecting the data transmission performance between the terminal device and the network device. The technical solution of this application can avoid this problem.

[0015] Based on the first aspect, in one possible implementation, when the reporting quantity configured in the first reporting configuration includes parameters for characterizing the downlink channel state, the first uplink channel is the uplink channel of the first candidate cell.

[0016] Based on the first aspect, in one possible implementation, the first communication device sends the measurement result corresponding to the first reporting configuration, including: the first communication device sending the measurement result through a first uplink channel in a second time domain unit, where the second time domain unit is the time domain unit corresponding to the third time domain unit plus a time offset, the third time domain unit being either the receiving time domain unit of the first signaling, or the time domain unit of the acknowledgment character (ACK) feedback for the first signaling, or the effective time of the first signaling, or the latest effective time of the first signaling, and the first signaling being used to indicate handover to the first candidate cell. In this implementation, the specific time for the first communication device to report the measurement result is defined, ensuring that the terminal device correctly sends the measurement result, facilitating the network device's reception of the measurement result.

[0017] Based on the first aspect, in one possible implementation, the first uplink channel is indicated by the first information. In other words, the transmission parameters of the first uplink channel are indicated by the first information. In this implementation, the network device triggers the terminal device to report the measurement results corresponding to the first reporting configuration through the first information, and the network device schedules the first uplink channel through the first information. This helps to reduce the indication signaling overhead.

[0018] Based on the first aspect, in one possible implementation, the first uplink channel is either the uplink channel used for scheduling the random access response message corresponding to the first candidate cell; or the uplink channel used for the radio resource control (RRC) establishment completion message corresponding to the first candidate cell; or the pre-configured uplink channel corresponding to the first candidate cell; or the Nth uplink channel corresponding to the first candidate cell, where N is an integer greater than or equal to 1. This implementation also illustrates another possible implementation of the first uplink channel, enriching the scheme's implementation possibilities.

[0019] Based on the first aspect, in one possible implementation, the first information is further used to schedule a second uplink channel, and the method further includes: the first communication device ignoring the second uplink channel scheduled by the first information. In this implementation, if the terminal device reports measurement results through the default uplink channel of the first candidate cell, and the first information also schedules a corresponding second uplink channel, then the terminal device can ignore the second uplink channel. This facilitates network devices scheduling the second uplink channel for other terminal devices and avoids resource waste.

[0020] Based on the first aspect, in one possible implementation, the first information is further used to schedule a second uplink channel. The first information also includes a first field indicating whether the second uplink channel is ignored. The method further includes: when the first field indicates that the second uplink channel is ignored, the first communication device does not perform uplink data transmission through the second uplink channel of the serving cell; or, when the first field indicates that the second uplink channel is not ignored, the first communication device performs uplink data transmission through the second uplink channel of the serving cell. In this implementation, if the terminal device reports measurement results through the default uplink channel of the first candidate cell, and the first information also schedules the corresponding second uplink channel, the first information also includes a first field to indicate whether the terminal device can use the first uplink channel for data transmission. On the one hand, this implementation can avoid resource waste. For example, if the terminal device does not use the second uplink channel, but the network device assumes that the second uplink channel has been scheduled for the terminal device, then the network device will not schedule the second uplink channel for other terminal devices, thus leading to resource waste. On the other hand, this implementation can avoid resource conflicts. For example, if the terminal device uses the second uplink channel for data transmission, but the network device schedules the second uplink channel for other terminal devices. This can lead to resource conflicts between multiple terminal devices, affecting communication.

[0021] Based on the first aspect, in one possible implementation, when the first condition is met, the first information further includes a first field. The first condition includes: a reporting configuration for candidate cells is configured, and the reporting quantity configured for the candidate cells includes at least one of CQI, RI, and PMI; the reporting configuration for candidate cells includes a first reporting configuration for the first candidate cell. This implementation limits the scenario where the first information includes the first field. The above first condition can also be alternatively described as: the first condition includes: a reporting configuration for candidate cells is configured, and the reporting quantity configured for the candidate cells includes parameters characterizing the downlink channel state.

[0022] Based on the first aspect, in one possible implementation, before the first communication device receives the first information, the method further includes: the first communication device receiving second information, the second information being used to indicate a first reporting configuration, wherein the reporting quantity configured in the first reporting configuration includes RSRP, or includes at least one of CQI, RI, and PMI. In this implementation, the first communication device receives relevant information about the first reporting configuration, facilitating the first communication device to determine the reporting content in the measurement results of the first candidate cell in conjunction with the first reporting configuration.

[0023] Based on the first aspect, in one possible implementation, the second information is also used to indicate at least one of the following: the triggering status associated with the one or more measurement resources or the first reporting configuration.

[0024] A second aspect of this application provides a communication method applied to a second communication device, which is a network device or a device applied to a network device. For example, the method may include a chip, chip system, module, processing unit, control unit, or circuit within the network device; specific applications are not limited in this application. It should be noted that in this application, the term "network device" can refer to the network device itself or to a chip, functional module, or integrated circuit within the network device that performs the method provided in this application; specific applications are not limited in this application. The method includes: the second communication device sending first information, which instructs the reporting of measurement results corresponding to a first reporting configuration. Then, the second communication device receives the measurement results corresponding to the first reporting configuration, wherein the measurement results are measurement results of reference signals corresponding to one or more measurement resources associated with the first reporting configuration, and these one or more measurement resources are measurement resources corresponding to a first candidate cell.

[0025] In the above technical solution, the second communication device receives first information, which is used to instruct the reporting of measurement results corresponding to the first reporting configuration. The second communication device receives the measurement results corresponding to the first reporting configuration. This facilitates the second communication device in selecting a suitable candidate cell for the first communication device based on the measurement results. Alternatively, it facilitates the second communication device in determining the transmission parameters of the first candidate cell based on the measurement results and transmitting the data with the first communication device through these transmission parameters. This helps ensure the communication quality between the terminal device and the network device in the first candidate cell. For example, after the terminal device switches to the first candidate cell, the terminal device and the network device obtain channel state information through a traditional channel measurement process. The traditional channel measurement process results in a large delay for the network device to obtain channel state information. During the time period corresponding to the traditional channel measurement process, the network device lacks the channel state information of the first candidate cell, making efficient data transmission to the terminal device impossible and affecting the data transmission performance between the terminal device and the network device. The technical solution of this application can avoid this problem.

[0026] Based on the second aspect, in one possible implementation, the measurement results are carried on a first uplink channel, which is either the uplink channel of the serving cell or the uplink channel of the first candidate cell. Two implementation methods for receiving measurement results are provided, facilitating network devices to receive the measurement results.

[0027] Based on the second aspect, in one possible implementation, the first uplink channel is determined according to the reporting amount configured in the first reporting configuration. In this implementation, the uplink channel carrying the measurement result is determined according to the reporting amount corresponding to the first reporting configuration. This ensures that the terminal device correctly transmits the measurement result, facilitating the network device's reception of the measurement result.

[0028] Based on the second aspect, in one possible implementation, when the reporting quantity configured in the first reporting configuration includes RSRP, the first uplink channel is the uplink channel of the serving cell. In this implementation, if the reporting quantity includes RSRP, which is used to characterize the signal quality of the reference signal, then the second communication device can receive the measurement results through the uplink channel of the serving cell. It can be understood that if the reporting quantity includes RSRP, it indicates that the terminal device is in a beam management process, that is, the network device first selects a candidate cell through the RSRPs of each candidate cell. In other words, the terminal device is still within the serving cell, and the network device can receive the measurement results through the uplink channel of the serving cell.

[0029] Based on the second aspect, in one possible implementation, the second communication device receives the measurement result corresponding to the first reporting configuration, including: the second communication device receives the measurement result through a first uplink channel in a first time domain unit, where the first time domain unit is the time domain unit for sending the first information plus the time domain unit corresponding to the time offset. In this implementation, the specific time for the second communication device to receive the measurement result is defined, ensuring that the network device correctly receives the measurement result.

[0030] Based on the second aspect, in one possible implementation, when the reporting quantity configured in the first reporting configuration includes parameters characterizing the signal quality of the reference signal, the first uplink channel is the uplink channel of the serving cell. In this implementation, if the reporting quantity includes parameters characterizing the signal quality of the reference signal, it can be understood that the terminal device is in a beam management process, and the network device selects a candidate cell for the terminal device during this beam management process. That is, the terminal device is still within the serving cell, and the network device can receive the measurement results through the uplink channel of the serving cell.

[0031] Based on the second aspect, in one possible implementation, the parameters used to characterize the signal quality of the reference signal include at least one of the following: RSRP or SINR.

[0032] Based on the second aspect, in one possible implementation, the reporting quantity configured in the first reporting configuration includes at least one of CQI, RI, and PMI, and the first uplink channel is the uplink channel of the first candidate cell. In this implementation, if the reporting quantity includes parameters characterizing the downlink channel state, it can be understood that the terminal device has already switched to or will switch to the first candidate cell. Therefore, after the terminal device switches to the first candidate cell, it can send the measurement result through the uplink channel of the first candidate cell. Correspondingly, the network device can receive the measurement result through the uplink channel of the first candidate cell. Then, the network device can transmit with the terminal device based on the channel state information indicated by the measurement result. The network device does not need to obtain channel state information through the traditional channel measurement process. The traditional channel measurement process causes a delay in obtaining channel state information. During this delay, the network device does not have the channel state information of the first candidate cell, and cannot perform efficient data transmission for the terminal device, affecting the data transmission performance between the terminal device and the network device. The technical solution of this application can avoid this problem.

[0033] Based on the second aspect, in one possible implementation, the second communication device receives the measurement result corresponding to the first reporting configuration, including: the second communication device receives the measurement result through a first uplink channel in a second time domain unit. The second time domain unit is the time domain unit corresponding to the third time domain unit plus a time offset. The third time domain unit is either the time domain unit for sending the first signaling, or the time domain unit for the ACK feedback of the first signaling, or the effective time of the first signaling, or the latest effective time of the first signaling. The first signaling is used to indicate handover to the first candidate cell. In this implementation, the specific time for the second communication device to receive the measurement result is defined, enabling the network device to correctly receive the measurement result.

[0034] Based on the second aspect, in one possible implementation, the first uplink channel is indicated by the first information. In other words, the transmission parameters of the first uplink channel are indicated by the first information. In this implementation, the network device triggers the terminal device to report the measurement results corresponding to the first reporting configuration through the first information, and the network device schedules the first uplink channel through the first information. This helps to reduce the indication signaling overhead.

[0035] Based on the second aspect, in one possible implementation, the first uplink channel is either the uplink channel used for scheduling the random access response message corresponding to the first candidate cell; or the uplink channel used for the RRC establishment completion message corresponding to the first candidate cell; or the pre-configured uplink channel corresponding to the first candidate cell; or the Nth uplink channel corresponding to the first candidate cell, where N is an integer greater than or equal to 1. This implementation also illustrates another possible implementation of the first uplink channel, enriching the scheme's implementation possibilities.

[0036] Based on the second aspect, in one possible implementation, the first information is also used to schedule the second uplink channel. The first information also includes a first field indicating whether the second uplink channel should be ignored. In this implementation, if the terminal device reports measurement results through the default uplink channel of the first candidate cell, and the first information also schedules the corresponding second uplink channel, the first information also includes a first field to indicate whether the terminal device can use the first uplink channel for data transmission. On the one hand, this implementation can avoid resource waste. For example, if the terminal device does not use the second uplink channel, but the network device assumes the second uplink channel has already been scheduled for that terminal device, then the network device will not schedule the second uplink channel for other terminal devices, leading to resource waste. On the other hand, this implementation can avoid resource conflicts. For example, if the terminal device uses the second uplink channel for data transmission, but the network device schedules the same second uplink channel for other terminal devices, this can lead to resource conflicts between multiple terminal devices, affecting communication.

[0037] Based on the second aspect, in one possible implementation, when the first condition is met, the first information further includes a first field.

The first condition includes: a reporting configuration for the candidate cell is configured, and the reporting quantity configured in the reporting configuration for the candidate cell includes parameters characterizing the downlink channel state. This implementation limits the scenario where the first information includes the first field.

[0073] Based on the fourth aspect, in one possible implementation, the second information is also used to indicate at least one of the following: one or more measurement resources, or the triggering status associated with the first reporting configuration.

[0074] A fifth aspect of this application provides a communication device comprising a processor and a memory. The memory stores computer programs or computer instructions, and the processor is configured to call and execute the computer programs or computer instructions stored in the memory, causing the processor to implement any one of the implementation methods of the first to second aspects. The communication device can be a communication equipment or a device applied to a communication equipment. For example, it may be a chip, chip system, module, processing unit, control unit, or circuit in a communication equipment.

[0075] Optionally, the communication device may also include a transceiver, and the processor is used to control the transceiver to send and receive signals.

[0076] A sixth aspect of this application provides a communication device, including a processor and an interface circuit. The processor is configured to communicate with other devices via the interface circuit and to execute the method described in any one of the first to second aspects. The processor may include one or more devices. The communication device may be a communication equipment or a device applied to a communication equipment. For example, a chip, chip system, module, processing unit, control unit, or circuit in a communication equipment.

The memory may be located within or outside the communication device. The processor may include one or more processors.

[0079] The ninth aspect of this application provides a computer-readable storage medium including computer instructions that, when executed on a computer, cause the computer to perform any of the implementations of the first to second aspects.

[0080] The tenth aspect of this application provides a chip device, including a processor for calling a computer program or computer instructions in memory to cause the processor to execute any one of the implementations of the first to second aspects described above.

[0081] Optionally, the processor is coupled to the memory via an interface.

[0082] Optionally, the memory is either built into the chip device or connected to the chip device.

[0083] The eleventh aspect of this application provides a communication system, which includes a first communication device and a second communication device; the first communication device is used to perform the method as shown in the first aspect, and the second communication device is used to perform the method as shown in the second aspect.

[0084] As described in the above technical solution, the first communication device receives first information, which instructs the reporting of measurement results corresponding to the first reporting configuration. Then, the first communication device sends the measurement results corresponding to the first reporting configuration, wherein the measurement results are the measurement results of reference signals corresponding to one or more measurement resources associated with the first reporting configuration, and these one or more measurement resources are the measurement resources corresponding to the first candidate cell. This enables the first communication device to measure and report the reference signals of the first candidate cell. For the receiving device, the receiving device can determine whether to instruct the terminal device to switch from the serving cell to the first candidate cell based on the measurement results. This is beneficial for selecting a suitable cell for the terminal device and for ensuring communication quality. For example, the measurement results include the signal quality of the first candidate cell, and the network device can determine whether to instruct the terminal device to switch to the first candidate cell based on the signal quality of the first candidate cell. For example, if the signal quality of the first candidate cell is better than that of the serving cell, the network device can instruct the terminal device to switch to the first candidate cell. Alternatively, in a scenario where the terminal device has already switched to or will switch to the first candidate cell, the receiving device can determine the transmission parameters of the first candidate cell based on the measurement results. The receiving device can then transmit data with the terminal device using the transmission parameters of the first candidate cell. This approach helps ensure communication quality between the terminal device and network device in the first candidate cell. Furthermore, before switching to the first candidate cell, the terminal device measures the reference signal of the first candidate cell to obtain measurement results. These measurement results include channel state information. The terminal device then reports the measurement results. When the terminal device switches to the first candidate cell, the network device can transmit data with the terminal device based on the channel state information indicated by the measurement results. The network device does not need to obtain channel state information through the traditional channel measurement process. The traditional channel measurement process causes a delay in obtaining channel state information. During this delay, the network device lacks the channel state information of the first candidate cell, making efficient data transmission for the terminal device impossible and affecting the data transmission performance between the terminal device and the network device. The technical solution of this application avoids this problem. Attached Figure Description

This enables the first communication device to measure and report reference signals for a first candidate cell. For the receiving device, the receiving device can determine whether to instruct the terminal device to switch from the serving cell to the first candidate cell based on the measurement results. This is beneficial for selecting a suitable cell for the terminal device and ensuring the communication quality between the terminal device and the network device. Alternatively, the receiving device can determine the transmission parameters of the first candidate cell based on the measurement results and transmit them to the terminal device using these transmission parameters. This is beneficial for ensuring the communication quality between the terminal device and the network device in the first candidate cell.

[0101] The communication systems to which this application applies include terminal equipment and network equipment. Terminal equipment and network equipment are described below.

[0102] Terminal equipment, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), customer premises equipment (CPE), etc., refers to devices that include wireless communication capabilities (providing voice / data connectivity to users). Examples include handheld devices with wireless connectivity, in-vehicle devices, and machine-type communication (MTC) terminals.

For example, wireless terminals in self-driving can be drones, helicopters, or airplanes. For example, wireless terminals in vehicle-to-everything (V2X) can be in-vehicle equipment, vehicle-mounted equipment, in-vehicle modules, vehicles, or ships. Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, robot vacuums, speakers, or set-top boxes. The terminal device can also be a device or module that is connected to the communication system shown above and has corresponding communication functions. The terminal device usually contains a communication module, circuit or chip that performs the corresponding communication function, and the terminal device is also configured with program instructions for performing the corresponding communication function.

[0103] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, chip system, module, or control unit in the device or apparatus shown above; this application does not impose any specific limitation. It should also be noted that in this application, when referring to a terminal device, it can refer to the terminal device itself, or it can be replaced with a chip, functional module, or integrated circuit in the terminal device that performs the method provided in this application; this application does not impose any specific limitation.

[0104] A network device is a device deployed in a radio access network to provide wireless communication functions for terminal devices. Network devices may also be referred to as radio access network (RAN) entities, access nodes, network nodes, access network equipment, or communication devices, etc.

[0105] Specifically, the network equipment can be access network equipment for cellular systems related to the 3rd Generation Partnership Project (3GPP). For example, fourth-generation (4G) mobile communication systems, 5G mobile communication systems, or future mobile communication systems. The network equipment can also be access network equipment in open RAN (O-RAN or ORAN) or cloud radio access network (CRAN). Alternatively, the network equipment can also be access network equipment in a communication system resulting from the integration of two or more of the above communication systems.

[0106] Network equipment includes, but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), access point (AP) in wireless fidelity (WIFI) systems, macro base station, micro base station, wireless relay node, donor node, radio controller in CRAN scenarios, wireless backhaul node, transmission point (TP), or transmission and reception point (or transmit / receive point, TRP). Network equipment can also be access network equipment in 5G mobile communication systems. For example, next-generation Node B (gNB), TRP, TP in new radio (NR) systems, or one or more antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system. Alternatively, network devices can also be network nodes constituting a gNB or transmission point. Examples include centralized units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs). CUs and DUs can be separate entities or included in the same network element, such as a BBU. RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs). Alternatively, network devices can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in V2X technology, network devices can be roadside units (RSUs).

[0107] It should be noted that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open centralized unit (O-CU) or an open CU, DU can also be called an open distributed unit (O-DU), centralized unit control plane (CU-CP) can also be called an open centralized unit control plane (O-CU-CP) or an open CU-CP, centralized unit user plane (CU-UP) can also be called an open centralized unit user plane (O-CU-UP) or an open CU-UP, and RU can also be called an open radio unit (O-RU). This application does not impose any specific limitations. Any of the units CU, CU-CP, CU-UP, DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0108] Figure 1 is a schematic diagram of an ORAN system according to an embodiment of this application. The ORAN system includes a core network, access network equipment, and UE. Optionally, the ORAN system may also include other components besides those shown in Figure 1, which is not limited in this application.

[0109] Access network devices can communicate with the core network (CN) via a backhaul link. Access network devices can also communicate with the UE via an air interface. Specifically, the BBU in the access network device communicates with the core network via a backhaul link. The RU in the access network device communicates with at least one UE via an air interface. The BBU communicates with at least one RU via a fronthaul link; the BBU and RU may or may not be co-located.

[0110] A BBU consists of at least one CU and at least one DU, and the CU and DU can communicate with each other via at least one midhaul link.

[0111] In one possible implementation, as shown in Figure 2, the CU is a logical node carrying the radio resource control (RRC), service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the access network equipment. The CU can connect to network nodes such as the core network through interfaces, such as the E2 interface. Optionally, the CU can have some core network functions. The CU (e.g., the PDCP layer and / or higher) connects to the DU (e.g., the radio link control (RLC) layer and lower layers of the DU) through interfaces, such as the F1 interface. Optionally, the F1 interface can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the signaling procedures of F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0112] Optionally, as shown in Figure 2, the CU can be split into CU-CP and CU-UP. CU-CP is a logical node carrying the control plane (PDCP-C) layer, which carries the RRC layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be access and mobility function (AMF) network elements, such as the access and mobility management (AMF) function in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. CU-UP is a logical node carrying the user plane (PDCP-U) layer, which carries the SDAP layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. In the core network, network elements used to implement user plane functions, such as the user plane function (UPF) in a 5G system, are responsible for forwarding and receiving data in terminal devices. The above configuration of CU and DU is merely an example; in practical applications, the functions of CU and DU can be configured as needed. For example, CU or DU can be configured to have more protocol layer functions, or to have only some protocol layer processing functions. For instance, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of CU or DU can be divided according to service type or other system requirements, such as by latency, placing functions that need to meet low latency requirements in the DU and functions that do not need to meet such latency requirements in the CU.

[0113] In one possible implementation, as shown in Figure 2, the DU is a logical node carrying the RLC layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, the DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0114] In one possible implementation, as shown in Figure 2, the RU is a logical node carrying both lower physical layer (PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP transmission reception point (TRP), a remote radio head (RRH), or other similar entities. In some examples, the Low-PHY includes PHY processing functions such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a wireless link.

[0115] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through the Lower-Layer Split CUS-Plane (LLS-CUS) interface. LLS-CUS may include a Lower-Layer Split control (LLS-C) interface and a Lower-Layer Split user (LLS-U) interface, providing the control plane (C-Plane) and user plane (U-Plane) respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and RU. The DU and RU exchange management information via a Lower-Layer Split management (LLS-M) interface on the fronthaul link; the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0116] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0117] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples.

[0118] It should be noted that network devices can be devices or apparatuses with chips, or devices or apparatuses with integrated circuits, or chips, chip systems, modules, or control units in the devices or apparatuses shown above; this application does not impose any specific limitations. It should also be noted that in this application, when referring to network devices, it can refer to the network device itself, or it can be replaced with the chips, functional modules, or integrated circuits in the network device that implement the methods provided in this application; this application does not impose any specific limitations.

[0119] Please refer to Figure 3, which is a schematic diagram of the architecture of the communication system 10 used in the embodiments of this application. As shown in Figure 3, the communication system includes RAN 100. Optionally, the communication system 10 also includes a core network 200 and an Internet 300. RAN 100 includes at least one RAN node (110a and 110b in Figure 3, collectively referred to as 110), and may also include at least one terminal device (120a-120j in Figure 3, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 3). Terminal device 120 is wirelessly connected to RAN node 110, and RAN node 110 is wirelessly or wired connected to core network 200. The core network device in core network 200 and RAN node 110 in RAN 100 can be independent and different physical devices, or they can be the same physical device integrating the logical functions of the core network device and the logical functions of the RAN node. Terminal devices and RAN nodes can be interconnected via wired or wireless means.

[0120] The technical terms used in this application are described below.

[0121] Beam: A beam is a communication resource. A beam can be wide, narrow, or other types of beam. Beamforming techniques can be beamforming technology or other methods. Beamforming technologies include digital beamforming, analog beamforming, and hybrid digital / analog beamforming. Different beams can be considered different resources.

[0122] In the NR protocol, a beam can be referred to as a spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, quasi-colocation (QCL) information, QCL assumption, or QCL indication, etc. The beam can be indicated by the transmission configuration indicator state (TCI-state) parameter or by the spatial relation parameter. Therefore, in this application, the beam can be replaced by spatial domain filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI-state (where TCI-state includes uplink TCI-state and downlink TCI-state), or spatial relation, etc. The above terms are also equivalent to each other. The beam can also be replaced with other beam-related terms, which are not limited herein.

[0123] The beam used to transmit signals can be called a transmission beam (Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting. The transmission beam can also be called a downlink beam.

[0124] The beam used to receive signals can be called a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting. The reception beam can also be called the uplink beam. The uplink transmission beam can be indicated by any of the following: spatial relation, uplink TCI-state, or sounding reference signal (SRS) resource (indicating the transmission beam using that SRS).

[0125] The transmit beam refers to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna. The receive beam refers to the distribution of signal strength in different directions in space of the wireless signal received from the antenna.

[0126] Beams are generally associated with resources. For example, during beam measurement, network devices measure different beams using different resources, and the terminal devices provide feedback on the measured resource quality, allowing the network devices to determine the quality of the corresponding beam. During data transmission, beam information is also indicated through its corresponding resources. For instance, network devices use the TCI field in downlink control information (DCI) to indicate beam information to the terminal devices.

[0127] Resources: In communication protocols, reference signals are configured as resources. Network devices allocate various reference signals to terminal devices as resources. Resource configuration information can include parameters related to the reference signal, such as its time-frequency resource location, number of ports, and time-domain type. The time-domain type can also be understood as the type of resource. For example, the time-domain type can be periodic, semi-persistent, or aperiodic. Semi-persistent can also be called semi-static.

[0128] Resources can be either uplink or downlink signal resources. Uplink signals include, but are not limited to, sounding reference signals (SRS) and demodulation reference signals (DMRS). Downlink signals include, but are not limited to, channel state information reference signals (CSI-RS), cell specific reference signals (CS-RS), user equipment specific reference signals (US-RS), demodulation reference signals (DMRS), and synchronization signal / physical broadcast channel blocks (SS / PBCH blocks). The SS / PBCH block can be abbreviated as synchronization signal block (SSB). CSI-RS also includes non-zero power CSI-RS (NZP CSI-RS) and zero power CSI-RS (ZP CSI-RS).

[0129] Resources can also be called measurement resources or reference signal resources. In other words, resources, measurement resources, and reference signal resources are interchangeable. The following text will use measurement resources as an example.

[0130] Serving cell: The serving cell can be the primary cell (Pcell), secondary cell (Scell), or primary secondary cell (PScell) of the terminal device. Cells using the primary component carrier (PCC) can be called Pcells, and cells using the secondary component carrier (SCC) can be called Scells.

[0131] Candidate cell: A candidate cell for the terminal device. For example, a candidate cell can be a neighboring cell of the terminal device's serving cell. The physical cell identifier (PCI) of the candidate cell is different from that of the terminal device's serving cell.

[0132] Currently, in cellular network communication systems, terminal devices communicate with network devices based on cells. Each cell has corresponding transmission parameters, such as time-frequency resources, bandwidth, modulation and coding scheme, and subcarrier spacing. When a terminal device is located within the signal coverage area of ​​a cell, the network device transmits data with the terminal device using the transmission parameters of that cell.

[0133] As a terminal device moves, it moves from the signal coverage area of ​​one cell to the signal coverage area of ​​another. The network device can instruct the terminal device to hand over to another cell. Specifically, before the terminal device performs a cell handover, it needs to perform cell measurements. Specifically, the terminal device measures the reference signals corresponding to the measurement resources of one or more candidate cells to obtain the signal quality corresponding to each of the candidate cells. When the terminal device finds that the signal quality of a candidate cell is stronger than that of its serving cell, it can report the measurement results to the network device. Then, the network device sends a cell handover signaling to the terminal device based on the measurement results. The cell handover signaling is used to instruct the terminal device to hand over to a target candidate cell. This target candidate cell is one of the terminal device's candidate cells. The terminal device hands over to the target candidate cell according to the cell handover signaling. The terminal device transmits data with the network device in the target candidate cell. As shown in Figure 4, the terminal device moves from the serving cell to candidate cell #2. The terminal device measures the signal quality corresponding to candidate cells #1 and #2 respectively and reports it to the network device. If the network device finds that the signal quality of candidate cell #2 is better than that of the serving cell based on the measurement results reported by the terminal device, the network device can instruct the terminal device to switch from the serving cell to candidate cell #2.

[0134] It should be noted that the network equipment belonging to the serving cell (i.e., the network equipment managing the serving cell) and the network equipment belonging to the candidate cell can be the same network equipment or different network equipment; this application does not impose any specific restrictions. The following text mainly uses the example of the network equipment belonging to the serving cell and the network equipment belonging to the candidate cell being the same network equipment to introduce the technical solution of this application.

[0135] Therefore, how the terminal device should initiate signal measurement of the candidate cell is a problem worth considering. Further, as shown in Figure 5, after the terminal device switches to the target candidate cell, before data transmission occurs between the terminal device and the network device, the network device sends channel status information (CSI) measurement and reporting configuration to the terminal device. Then, the network device sends a reference signal to the terminal device. The terminal device measures the reference signal of the target candidate cell based on the CSI measurement and reporting configuration and reports the CSI of the target candidate cell. Then, the network device determines the transmission parameters of the target candidate cell based on the CSI of the target candidate cell. The network device then transmits data with the terminal device based on the transmission parameters of the target candidate cell. It can be seen that the process of the network device obtaining the CSI of the target candidate cell introduces a significant delay. During this delay, the network device does not have the CSI of the target candidate cell, and therefore cannot transmit data efficiently with the terminal device, affecting data transmission performance. Therefore, how to improve the data transmission performance of the terminal device after switching to the target candidate cell is one of the problems this application aims to solve. This application provides corresponding technical solutions, which are described in detail in the following embodiments.

[0136] The communication system to which the technical solution provided in this application applies includes a first communication device and a second communication device. The first communication device is a terminal device, or a device applied to a terminal device. For example, it may be a chip, chip system, module, processing unit, control unit, or circuit, etc., and this application does not limit its specific application. The second communication device is a network device, or a device applied to a network device. For example, it may be a chip, chip system, module, processing unit, control unit, or circuit, etc., and this application does not limit its specific application.

[0137] In this application, the time-domain unit can be a time-domain symbol, time slot, subframe, frame, second, millisecond, or other time unit, etc., and this application does not limit the specific unit.

[0141] The first information indicates that the measurement results corresponding to the first reporting configuration (ReportConfig) should be reported. The measurement results corresponding to the first reporting configuration are the measurement results of reference signals corresponding to one or more measurement resources associated with the first reporting configuration. The first reporting configuration specifies reporting quantities. The first communication device can measure the one or more measurement resources according to the first reporting configuration to obtain the measurement results corresponding to the first reporting configuration. The reporting quantities included in the measurement results corresponding to the first reporting configuration can be the same as the reporting quantities configured in the first reporting configuration. For example, if the reporting quantities configured in the first reporting configuration include RSRP, then the measurement results corresponding to the first reporting configuration include RSRP. As another example, if the reporting quantities configured in the first reporting configuration include CQI, then the measurement results corresponding to the first reporting configuration include CQI. For more information about the first reporting configuration, please refer to the relevant descriptions below.

[0142] The one or more measurement resources are the measurement resources corresponding to the first candidate cell of the first communication device. Optionally, the one or more measurement resources belong to the measurement resource configuration.

[0143] In one possible implementation, the measurement resource configuration includes an index of the one or more measurement resources and an identifier of the candidate cell corresponding to each measurement resource.

[0144] In another possible implementation, the measurement resource configuration includes a measurement resource list and a cell identifier list. The measurement resource list includes the indexes of one or more measurement resources, and the cell identifier list includes the identifiers of the candidate cells corresponding to those measurement resources. There is a one-to-one correspondence between the indexes of the measurement resources in the measurement resource list and the cell identifiers in the cell identifier list. For example, the measurement resource list includes indexes A, B, C, and D. Index A is the index of measurement resource 1, index B is the index of measurement resource 2, index C is the index of measurement resource 3, and index D is the index of measurement resource 4. The cell identifier list includes cell identifier 1, cell identifier 2, cell identifier 3, and cell identifier 3. Cell identifier 1 is the identifier of candidate cell 1, cell identifier 2 is the identifier of candidate cell 2, and cell identifier 3 is the identifier of candidate cell 3. Therefore, measurement resources 1 and 2 are the measurement resources of candidate cell 1, and measurement resource 3 is the measurement resource of candidate cell 2. Measurement resource 4 is the measurement resource for candidate cell 3.

[0145] Optionally, the first information is used to indicate a first trigger state, which is associated with a first reporting configuration. This triggers the reporting of the measurement results corresponding to the first reporting configuration associated with the first trigger state.

[0146] Optionally, the first information is carried in downlink control information (DCI) or medium access control element (MAC CE).

[0147] 602. The first communication device measures the reference signal corresponding to one or more measurement resources to obtain the measurement result corresponding to the first reporting configuration.

[0148] The reference signal corresponding to the one or more measurement resources is the reference signal carried on the one or more measurement resources. For example, as shown in Figure 4, the first candidate cell is candidate cell #2, and the one or more measurement resources are the measurement resources of candidate cell #2. The one or more measurement resources are used to measure the signal quality of the first candidate cell, or to measure the downlink channel state between the second communication device and the first communication device in the first candidate cell.

[0149] 603. The first communication device sends the measurement results corresponding to the first reporting configuration. Correspondingly, the second communication device receives the measurement results corresponding to the first reporting configuration.

[0150] The measurement results corresponding to the first reporting configuration are carried on the first uplink channel.

[0151] Optionally, the first uplink channel is determined based on the reporting amount configured in the first reporting configuration. In other words, the first communication device determines the first uplink channel based on the reporting amount configured in the first reporting configuration, and sends the measurement results corresponding to the first reporting configuration through the first reporting channel. This ensures that the terminal device and the network device align the uplink channels for sending measurement results, facilitating the network device's reception of the measurement results.

[0152] The following describes two possible implementations of the first uplink channel.

[0153] Implementation Method 1: The first uplink channel is the uplink channel of the serving cell.

[0154] Optionally, when the reporting quantity configured in the first reporting configuration includes parameters characterizing the signal quality of the reference signal, the first uplink channel is the uplink channel of the serving cell. The parameters characterizing the signal quality of the reference signal include at least one of the following: RSRP or SINR. For example, if the reporting quantity configured in the first reporting configuration includes RSRP, the first uplink channel is the uplink channel of the serving cell.

[0155] If the reporting quantity configured in the first reporting configuration includes parameters characterizing the signal quality of the reference signal, the first communication device transmits the measurement result corresponding to the first reporting configuration through the first uplink channel of the serving cell. For example, if the reporting quantity configured in the first reporting configuration includes at least one of the following: RSRP or SINR, the first communication device transmits the measurement result corresponding to the first reporting configuration through the first uplink channel of the serving cell. It is understood that if the reporting quantity configured in the first reporting configuration is a parameter characterizing the signal quality of the reference signal, it indicates that the terminal device is in a beam management process. The network device selects a candidate cell for the terminal device through the beam management process. The terminal device is located in the serving cell, therefore the terminal device can transmit the measurement result through the uplink channel of the serving cell.

[0156] Optionally, the first uplink channel is scheduled by the first information. In other words, the transmission parameters of the first uplink channel are scheduled by the first information. The transmission parameters include at least one of the following: time-frequency resources, bandwidth, modulation and coding scheme, or subcarrier spacing. For example, the first information is carried in a DCI, which schedules the first uplink channel. That is, if the reporting quantity configured in the first reporting configuration includes parameters characterizing signal quality, then it can be understood that the first uplink channel scheduled by the first information is the uplink channel of the serving cell. It should be noted that this embodiment uses the example of the first uplink channel being scheduled by the first information for illustration. In reality, the second communication device can also schedule the first uplink channel through other information or separate information; this application does not limit the specifics.

[0157] In this implementation, the first piece of information includes the identifier of the serving cell.

[0158] In this implementation, the first communication device transmits the first uplink channel through the transmission parameters of the first uplink channel of the serving cell. This first uplink channel carries the measurement results corresponding to the first reporting configuration. For example, the first uplink channel is a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH). The first uplink channel can also be referred to as first uplink information. The first uplink information is uplink MAC CE or uplink control information (UCI).

[0159] Optionally, step 602 specifically includes: the first communication device sending the measurement result corresponding to the first reporting configuration through the first uplink channel of the serving cell in the first time domain unit. Correspondingly, the second communication device receiving the measurement result corresponding to the first reporting configuration through the first uplink channel of the serving cell in the first time domain unit.

[0160] In this configuration, the first time-domain unit is the time-domain unit for receiving the first information plus the time-domain unit corresponding to the time offset. For example, the first uplink channel of the serving cell occupies time-domain symbols 1 to 4 in each time slot. The time-domain unit for receiving the first information is time slot 0, and the time offset is one time slot; therefore, the first time-domain unit is time slot 1. The first communication device sends the measurement result corresponding to the first reporting configuration through time-domain symbols 1 to 4 in time slot 1 of the serving cell. This ensures that the terminal device correctly sends the measurement result and facilitates the network device's reception of the measurement result.

[0161] For example, the time offset can be 1 time slot, 2 time slots, 3 time slots, 4 time slots, or 5 time slots.

[0162] Optionally, the time offset may be predefined, specified by the communication protocol, or configured by the network device for the terminal device; this application does not impose any specific limitations on this. For example, the first piece of information may carry the time offset. It should be noted that the time offset may also be carried through other information; this application does not impose any specific limitations on this either.

[0163] Implementation Method 2: The first uplink channel is the uplink channel of the first candidate cell.

[0164] Optionally, when the reporting amount configured in the first reporting configuration includes parameters characterizing the downlink channel state, the first uplink channel is the uplink channel of the first candidate cell. The parameters characterizing the downlink channel state include at least one of the following: CQI, RI, or PMI. For example, if the reporting amount configured in the first reporting configuration includes at least one of CQI, RI, and PMI, the first uplink channel is the uplink channel of the first candidate cell.

[0165] The first candidate cell can also be called the target cell. The first candidate cell is the cell to which the first communication device will hand over, or the cell to which the first communication device has already handed over. The first candidate cell is indicated by the first signaling. It should be noted that the first signaling can also be called cell handover signaling. If the first communication device receives multiple cell handover signaling messages, the first signaling message is the last cell handover signaling message received by the first communication device before reporting the measurement results. For more information on the first signaling message, please refer to the relevant description in step 601a below.

[0166] If the reporting quantity configured in the first reporting configuration includes parameters characterizing the downlink channel state, the first communication device transmits the measurement result corresponding to the first reporting configuration through the first uplink channel of the first candidate cell. For example, if the reporting quantity configured in the first reporting configuration includes at least one of the following: CQI, RI, or PMI, the first communication device transmits the measurement result corresponding to the first reporting configuration through the first uplink channel of the first candidate cell. It is understood that if the reporting quantity includes parameters characterizing the downlink channel state, it indicates that the terminal device will switch to or has already switched to the first candidate cell. Therefore, after the terminal device switches to the first candidate cell, it can transmit the measurement result through the first uplink channel of the first candidate cell. Correspondingly, the network device can receive the measurement result through the first uplink channel of the first candidate cell. Then, the network device can transmit data to the terminal device based on the channel state information of the first candidate cell in the measurement result. The network device does not need to obtain the channel state information of the first candidate cell through a traditional channel measurement process. Traditional channel measurement processes result in a delay in acquiring the channel state information of the first candidate cell. During this delay, the network device lacks the channel state information of the first candidate cell, preventing efficient data transmission between the network device and the terminal device and impacting data transmission performance between them. The technical solution of this application avoids this problem.

[0167] In this implementation, the first communication device transmits the measurement results corresponding to the first reporting configuration through the first uplink channel of the first candidate cell. Alternatively, the first communication device transmits the first uplink channel through the time-frequency resources of the first candidate cell. This first uplink channel carries the measurement results corresponding to the first reporting configuration. Or, the first communication device transmits the first uplink channel through the transmission parameters of the first uplink channel of the first candidate cell. This first uplink channel carries the measurement results corresponding to the first reporting configuration.

[0168] Based on implementation method two, optionally, the embodiment shown in Figure 6 further includes step 601a, which can be performed before step 603.

[0169] 601a. ​​The second communication device sends a first signaling message. Correspondingly, the first communication device receives the first signaling message.

[0170] The first signaling instruction is used to instruct the first communication device to switch to the first candidate cell. The first candidate cell is a candidate cell for the first communication device. After receiving the first signaling instruction, the first communication device can switch from the serving cell to the first candidate cell. For example, as shown in Figure 4, the terminal device switches from the serving cell to candidate cell #2.

[0171] Optionally, the first signaling may also be called handover signaling or cell handover signaling; this application does not specify the name of the first signaling. The cell handover signaling may be an L1 / L2 triggered mobility cell switch command media access control (LTM cell switch command MAC CE). Here, L1 refers to layer 1, and L2 refers to layer 2.

[0172] It should be noted that there is no fixed execution order between step 601a and steps 601 to 602, and this application does not impose any specific restrictions. For example, step 601a may be executed first, followed by steps 601 to 602; or steps 601 to 602 may be executed first, followed by step 601a; or, depending on the circumstances, steps 601a and steps 601 to 602 may be executed simultaneously, and this application does not impose any specific restrictions.

[0173] It should be noted that if step 601a is executed after step 601, after the first communication device receives the first information, the first communication device does not know which candidate cell's uplink channel the first uplink channel scheduled by the first information belongs to. In this case, the first communication device can buffer the first information. When the first communication device receives the first signaling, the first communication device can determine that the first uplink channel is the uplink channel of the first candidate cell through the first information. Then, the first communication device sends the measurement results corresponding to the first reporting configuration to the second communication device through the first uplink channel of the first candidate cell.

[0174] In the second implementation described above, this embodiment provides two possible implementation schemes for the first uplink channel. These will be described separately below.

[0175] Option 1: The first uplink channel is the uplink channel of the first information scheduling.

[0176] Optionally, if the reporting quantity configured in the first reporting configuration includes parameters for characterizing the downlink channel state, then it can be understood that the first uplink channel scheduled by the first information is the uplink channel of the first candidate cell. It should be noted that the second communication device may also schedule the first uplink channel for the first communication device through other information, which is not limited in this application.

[0177] Optionally, step 603 specifically includes: the first communication device sending the measurement result corresponding to the first reporting configuration through the first uplink channel of the first candidate cell in the second time domain unit. Correspondingly, the second communication device receiving the measurement result corresponding to the first reporting configuration through the first uplink channel of the first candidate cell in the second time domain unit. Here, the second time domain unit is the time domain unit corresponding to the third time domain unit plus a time offset. For example, if the third time domain unit is time slot 0 and the time offset is two time slots, then the second time domain unit is time slot 2. The first uplink channel is time domain symbol 2 and time domain symbol 3 in the time slot. Therefore, the first communication device sends the measurement result corresponding to the first reporting configuration through time domain symbol 2 and time domain symbol 3 in time slot 2 of the first candidate cell.

[0178] The following section introduces some possible implementations of the third time-domain unit.

[0179] Implementation Method 1: The third time domain unit is the receiving time domain unit for the first signaling. That is, the third time domain unit is the receiving time domain unit for the first communication device to receive the first signaling. For example, the third time domain unit is the time slot for the first communication device to receive the first signaling.

[0180] Implementation Method Two: The third time-domain unit is the time-domain unit for the ACK received in response to the first signaling feedback. That is, the third time-domain unit is the transmission time-domain unit for the first communication device to send the ACK in response to the first signaling feedback. Here, the ACK is used to indicate that the first communication device has received the first signaling. For example, the third time-domain unit is the transmission time-domain symbol for the first communication device to send the ACK in response to the first signaling feedback.

[0181] Implementation Method 3: The third time domain unit is the effective time of the first signaling. The calculation formula for the effective time of the first signaling can be found in Chapter 21 of the TS38.213 protocol version V18.5.0.

[0182] Implementation Method 4: The third time domain unit is the latest effective time of the first signaling. The calculation formula for the latest effective time of the first signaling can be found in Chapter 21 of the TS38.213 protocol version V18.5.0.

[0183] Option 2: The first uplink channel is the uplink channel scheduled by the random access response (RAR) message corresponding to the first candidate cell. That is, the uplink channel scheduled by the random access response message received by the first communication device in the first candidate cell. Alternatively, the first uplink channel is the uplink channel used by the radio resource control (RRC) establishment completion message corresponding to the first candidate cell. That is, the first uplink channel is the uplink channel used by the first communication device to send the RRC establishment completion message in the first candidate cell. Alternatively, the first uplink channel is the pre-configured uplink channel corresponding to the first candidate cell. That is, the uplink channel of the first candidate cell configured by the second communication device for the first communication device. For example, the pre-configured uplink channel is the physical uplink control channel (PUCCH) or the physical uplink shared channel (PUSCH). For example, a schedule-free PUSCH (configured grant PUSCH, CG-PUSCH). Alternatively, the first uplink channel is the Nth uplink channel corresponding to the first candidate cell, where N is an integer greater than or equal to 1. For example, the first uplink channel is the first uplink channel corresponding to the first candidate cell. That is, the Nth uplink channel of the first candidate cell scheduled by the second communication device for the first communication device. For example, the first uplink channel is the first uplink channel of the first candidate cell scheduled by the second communication device for the first communication device. As another example, the first uplink channel is the second uplink channel of the first candidate cell scheduled by the second communication device for the first communication device.

[0184] In this implementation, optionally, the first information is also used to schedule the second uplink channel. The second uplink channel is the uplink channel of the serving cell. For example, the first information includes the transmission parameters of the second uplink channel and the identifier of the serving cell. The following describes some possible behaviors of the first communication device with respect to this implementation.

[0185] Implementation method 1: The first communication device ignores the second uplink channel scheduled by the first information.

[0186] In this implementation, the terminal device reports the measurement results through the first uplink channel of the first candidate cell, while the first information schedules the second uplink channel, which the terminal device can ignore. This facilitates network devices in scheduling the second uplink channel for other terminal devices, avoiding resource waste.

[0187] Implementation Method Two: The first information also includes a first field, which indicates whether the second uplink channel is ignored. When the first field indicates that the second uplink channel is ignored, the first communication device does not perform uplink data transmission through the second uplink channel of the serving cell; or, when the first field indicates that the second uplink channel is not ignored, the first communication device performs uplink data transmission through the second uplink channel of the serving cell.

[0188] In this implementation, the first information also schedules a second uplink channel. The first information also includes a first field to indicate whether the terminal device can use the first uplink channel for data transmission. On one hand, this implementation avoids resource waste. For example, if the terminal device does not use the second uplink channel, but the network device assumes the second uplink channel has already been scheduled for that terminal device, the network device will not schedule the second uplink channel for other terminal devices, leading to resource waste. On the other hand, this implementation avoids resource conflicts. For example, if a terminal device uses the second uplink channel for data transmission, but the network device schedules the same second uplink channel for other terminal devices, this can lead to resource conflicts between multiple terminal devices, affecting communication.

[0189] Optionally, when the first condition is met, the first information further includes a first field. The first condition includes: a reporting configuration for the candidate cell is configured, and the reporting quantity configured for the candidate cell includes at least one of CQI, RI, and PMI; or, the reporting quantity configured for the candidate cell includes parameters used to characterize the downlink channel state. The reporting configuration for the candidate cell includes the first reporting configuration for the first candidate cell.

[0190] It should be noted that if the reporting quantity configured in the first reporting configuration includes at least one of RSRP and SINR, the first communication device sends the measurement results corresponding to the first reporting configuration through the first uplink channel of the serving cell. Optionally, if the first information also includes a first field, the first communication device may ignore the first field in the first information.

[0191] Optionally, the embodiment shown in FIG6 further includes step 600a. Step 600a may be performed before step 601.

[0192] 600a. The second communication device sends the second information. Correspondingly, the first communication device receives the second information.

[0193] The second information is used to indicate the first reporting configuration. The reporting quantity configured in the first reporting configuration includes at least one of the following: RSRP or SINR. Alternatively, the reporting quantity configured in the first reporting configuration includes at least one of CQI, RI, and PMI. Optionally, the first reporting configuration also configures the reporting method. For example, the reporting method is periodic reporting or non-periodic reporting.

[0194] Optionally, the second information is also used to indicate at least one of the following: the one or more measurement resources, or the first trigger state. The first trigger state is the trigger state associated with the first reporting configuration. It should be noted that the one or more measurement resources and the first trigger state can also be indicated by other information, which is not limited in this application.

[0195] Optionally, the one or more measurement resources belong to the measurement resource configuration. The relevant content regarding measurement resource configuration has already been introduced earlier and will not be repeated here.

[0196] Optionally, the first reporting configuration, the one or more measurement resources, and the first triggering state may be carried by the same signaling or different signaling, which is not limited in this application.

[0197] It should be noted that if the embodiment shown in Figure 6 further includes step 601a, step 600a can be performed before step 601a.

[0198] Optionally, the embodiment shown in FIG6 further includes step 600b, which may be performed before step 601.

[0199] 600b. The first communication device transmits capability information. Correspondingly, the second communication device receives the capability information.

[0200] The capability information includes at least one of the following:

[0201] Does the terminal device support measuring and reporting the reference signal of the candidate cell before cell handover? Or,

[0202] Does the terminal device support obtaining the channel state information of the candidate cell before cell handover?

[0203] In this embodiment, a first communication device receives first information. This first information is used to instruct the reporting of measurement results corresponding to a first reporting configuration. The first communication device sends the measurement results corresponding to the first reporting configuration. These measurement results are the measurement results of reference signals corresponding to one or more measurement resources associated with the first reporting configuration. These one or more measurement resources are measurement resources corresponding to a first candidate cell. This enables the first communication device to measure and report the reference signals of the first candidate cell. For the receiving device, the receiving device can determine whether to instruct the terminal device to switch from the serving cell to the first candidate cell based on the measurement results. This is beneficial for selecting a suitable cell for the terminal device and ensuring communication quality. Alternatively, in a scenario where the terminal device has already switched to or will switch to the first candidate cell, the receiving device can determine the transmission parameters of the first candidate cell based on the measurement results. The receiving device can then transmit data with the terminal device using the transmission parameters of the first candidate cell. This is beneficial for ensuring the communication quality between the terminal device and the network device in the first candidate cell. Furthermore, before switching to the first candidate cell, the terminal device measures the reference signals of the first candidate cell to obtain measurement results. These measurement results include channel state information. Then, the terminal device reports the measurement results. When a terminal device switches to the first candidate cell, the network device can transmit data with the terminal device based on the channel state information indicated by the measurement result. The network device does not need to obtain channel state information through the traditional channel measurement process. The traditional channel measurement process introduces a delay in obtaining channel state information. During this delay, the network device lacks the channel state information of the first candidate cell, making efficient data transmission to the terminal device impossible and affecting the data transmission performance between the terminal device and the network device. The technical solution of this application avoids this problem.

[0210] It should be noted that the communication device 700 may include a transmitting module but not a receiving module.

[0216] It should be noted that the communication device 700 may include a transmitting module but not a receiving module.

[0219] It should be understood that the specific procedures for each module to perform the above-mentioned corresponding processes have been described in detail in the above method embodiments, and will not be repeated here for the sake of brevity.

As shown in Figure 9, the terminal device includes a processor, a memory, and a transceiver. The memory can store computer program code, and the transceiver includes a transmitter 931, a receiver 932, radio frequency circuitry (not shown in the figure), an antenna 933, and input / output devices (not shown in the figure).

[0236] When data needs to be transmitted, the processor performs baseband processing on the data to be transmitted and outputs a baseband signal to the radio frequency (RF) circuit. The RF circuit then processes the baseband signal and transmits it outwards as electromagnetic waves via an antenna. When data is sent to the terminal device, the RF circuit receives the RF signal through the antenna. The RF circuit converts the RF signal back into a baseband signal and outputs it to the processor. The processor converts the baseband signal back into data and processes the data. For ease of explanation, Figure 9 only shows one memory, processor, and transceiver. In actual terminal device products, there may be one or more processors and one or more memories.
