Communication method, device and storage medium
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on December 8, 2023, with application number 202311691118.9 and application name "A Communication Method, Device and Storage Medium", the entire contents of which are incorporated by reference into this application. Technical Field
[0003] The present application relates to the field of communication technology, and in particular to a communication method, device, and storage medium. Background Art
[0004] The fifth generation mobile communication system (5G) can use high-frequency communication, that is, it uses ultra-high frequency band (such as 28 gigahertz (GHz)) signals to transmit data. A major problem with high-frequency communication is that the signal energy drops sharply with the transmission distance, resulting in a short signal transmission distance. To overcome this problem, high-frequency communication uses analog beam technology. By weighting the antenna array, the signal energy is concentrated within a smaller angle range to form a signal similar to a light beam (called an analog beam, or simply beam), thereby increasing the transmission distance. Both network devices and terminal devices use beams for transmission. When performing uplink and downlink data transmission, the network device and the terminal device need to use specific beams. Due to changes in the external environment or the movement of the terminal device, the quality of the beam used to transmit signals between the terminal device and the network device may decrease. Therefore, the terminal device and the network device need to obtain and readjust the beam for communication in order to improve the communication quality.
[0005] In one embodiment, the network device configures the terminal device with information such as resources for the reference signal to be measured. In a periodic reference signal measurement scheme, the terminal device can measure the reference signal based on the resources and other information configured by the network device when the measurement time arrives in each period, and feed back the measurement result information to the network device. The network device configures the beam for the terminal device based on the measurement result information. In an aperiodic or semi-persistent reference signal measurement scheme, when the network device determines that a reference signal measurement is required, the network device sends a signaling to the terminal device for triggering the reference signal measurement. The terminal device starts the reference signal measurement based on the received signaling. The terminal device feeds back the measurement result information to the network device. The network device configures the beam for the terminal device based on the measurement result information.
[0006] The above solutions show that when channel quality changes, even though the terminal device detects a decrease in the quality of the current serving beam, it still needs to wait for the next reference signal measurement period to arrive before it can begin measuring the reference signal. Alternatively, the terminal device needs to wait for the network device to issue a triggering instruction for reference signal measurement before it can perform reference signal measurement based on that instruction. These current solutions result in untimely reference signal measurement, which in turn leads to slow beam switching and frequent communication interruptions. Summary of the Invention
[0007] The present application provides a communication method, device, and storage medium for enabling a terminal device to more quickly initiate reference signal measurement, thereby reducing the occurrence of communication interruptions.
[0008] In a first aspect, the present application provides a communication method, which is executed by a terminal device, which may be a terminal device or a chip inside the terminal device.
[0009] A terminal device transmits first information via a first cell, the first information being used to instruct the terminal device to request reference signal measurement of a second cell. The terminal device receives at least one reference signal via the second cell. The terminal device measures the at least one reference signal and obtains at least one measurement result information.
[0010] It can be seen from the above scheme that the terminal device can trigger the measurement of the reference signal through the first information. That is to say, in the implementation method provided by the first aspect, the terminal device triggers the measurement of the reference signal, and the measurement result information obtained by the terminal device can also be referred to as: the measurement result information obtained by the measurement of the reference signal triggered by the terminal device. In this scheme, the terminal device does not have to wait for the measurement process of the reference signal triggered by the network device, that is, it does not have to wait for the arrival of the next reference signal measurement cycle before starting to measure the reference signal, or it does not have to wait for the instruction issued by the network device to trigger the reference signal measurement. This can speed up the subsequent beam switching process and thereby reduce the occurrence of communication interruptions.
[0011] The “measurement result information” in this application can be replaced by “reference signal measurement result information” or “measurement result”. For the sake of convenience, it is uniformly referred to as “measurement result information” in this document.
[0012] In one possible implementation of the first aspect, a terminal device determines a cell in which the terminal device transmits measurement result information, where the cell in which the terminal device transmits the measurement result information includes a third cell. The terminal device transmits second information via the third cell, where the second information may include (or may not include) part or all of the at least one measurement result information.
[0013] In another possible implementation, the second information may further include measurement result information obtained from measurement of a reference signal that is not triggered by the terminal device. The measurement result information obtained from measurement of a reference signal that is not triggered by the terminal device includes, for example, measurement result information obtained from a measurement process of a reference signal triggered by a network device, and / or measurement result information obtained from periodic reference signal measurement by the terminal device.
[0014] The reference signal measurement process triggered by the network device of the present application can be understood as follows: in an aperiodic (AP) or semi-persistent (SP) reference signal measurement scheme, when the network device determines that reference signal measurement is required, the network device sends a signaling to the terminal device for triggering reference signal measurement, and the terminal device starts reference signal measurement based on the received signaling and obtains measurement result information. The measurement result information can also be understood as the measurement result information obtained in the reference signal measurement process triggered by the network device.
[0015] The measurement result information obtained by the terminal device of the present application periodically measuring the reference signal can be understood as: information such as the resources of the reference signal configured by the network device for the terminal device to measure. In the periodic reference signal measurement scheme, the terminal device can measure the reference signal based on the resources configured by the network device and other information when the measurement time arrives within each period to obtain measurement result information. This measurement result information can also be understood as measurement result information obtained by the terminal device periodically measuring the reference signal.
[0016] In one possible implementation, the first information indicates that the terminal device requests measurement of a reference signal of the second cell (for example, the first information may include information for indicating that the terminal device requests measurement of a reference signal of the second cell). This implementation may also be understood as: the first information is used to indicate information that the terminal device requests measurement of a reference signal of the second cell, but does not indicate that the terminal device requests sending the measurement result of the reference signal of the second cell. In this case, the terminal device may trigger measurement of the reference signal (for example, subsequently measuring the reference signal), and the terminal device does not trigger sending of measurement result information (for example, not sending measurement result information); or, the terminal device may trigger measurement of the reference signal (for example, subsequently measuring the reference signal), and the terminal device also triggers sending of measurement result information (for example, sending the second information).
[0017] In another possible implementation, the first information is also used to indicate that the terminal device requests to send the measurement result of the reference signal of the second cell (for example, the first information may also include information used to indicate that the terminal device requests to send the measurement result of the reference signal of the second cell). In this case, the terminal device can trigger the measurement of the reference signal (for example, subsequently measure the reference signal), and the terminal device also triggers the sending of measurement result information (for example, sending the second information).
[0018] In a possible implementation provided in the first aspect, the first cell and the second cell may be different. In a possible implementation, when the terminal device determines that the second cell needs to measure the reference signal, the current beam quality of the second cell may be poor. In this case, if the terminal device still sends information for requesting measurement of the reference signal of the second cell through the second cell, the second network device may not receive the information, which in turn causes the reference signal measurement process requested by the terminal device to fail. In the case where the first cell may be different from the second cell, that is, the cell to which the terminal device sends the information for requesting measurement of the reference signal of the second cell may not be the second cell, but other cells, thereby improving the success rate of the terminal device's request for reference signal measurement this time.
[0019] In another possible implementation manner provided by the first aspect, the first cell and the second cell may also be the same, thereby improving solution flexibility.
[0020] In a second aspect, the present application provides a communication method, which is executed by a terminal device, which may be a terminal device or a chip inside the terminal device.
[0021] The terminal device sends first information via the first cell, the first information being used to indicate that the terminal device requests to send measurement result information. The terminal device sends second information via the third cell, the second information including at least one measurement result information.
[0022] In the implementation manner provided by the second aspect, the measurement result information included in the second information may include: measurement result information obtained by reference signal measurement triggered by the terminal device, and / or measurement result information obtained by reference signal measurement triggered by the network device.
[0023] In the implementation provided in the second aspect, the terminal device may trigger a process for transmitting measurement result information using the first information. That is, the terminal device may trigger the transmission of the measurement result information without having to wait for the process for transmitting the measurement result information to be triggered by the network device. The measurement result information included in the second information may include measurement result information obtained in a reference signal measurement process triggered by the network device and / or the terminal device.
[0024] In a possible implementation manner provided in the first aspect and / or the second aspect, the first information includes at least one of the following: information for indicating resources of a reference signal; information for indicating a second cell; information indicating a cell for sending measurement result information; information indicating resources for sending measurement result information; and information indicating a cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs. In this way, the terminal device can actively send some information it needs, thereby informing the network device side of its own needs, so that the network device can subsequently configure a reference signal for the terminal device that better meets the needs of the terminal device. In this application, "indication information of a cell for sending measurement result information" can also be replaced with "information for indicating a cell for sending measurement result information", and in this application, "indication information of resources for sending measurement result information" can also be replaced with "information for indicating resources for sending measurement result information".
[0025] In a possible implementation manner provided in the first aspect and / or the second aspect, the first information further includes information for indicating at least one of the following: the multiple reference signals requested to be measured by the terminal device are sent using the same downlink spatial domain filter; the multiple reference signals requested to be measured by the terminal device can be received simultaneously by the terminal device; the spatial domain filters corresponding to the multiple reference signals requested to be measured by the terminal device can be applied by the terminal device for simultaneous transmission; or, the resource of the reference signal requested to be measured by the terminal device belongs to the reference signal resource associated with N transmission receiving points, where N is a positive integer. In this way, the terminal device can actively send some information it needs, thereby informing the network device side of its own needs, so that the network device can subsequently configure a reference signal for the terminal device that better meets the needs of the terminal device.
[0026] In one possible implementation of the first and / or second aspects, a terminal device determines a first resource. The first resource is used to send information requesting reference signal measurement, and / or the first resource is used to send information requesting the transmission of reference signal measurement result information. The terminal device sends the first information via the first cell using the first resource. In this way, the terminal device can inform the network device of the purpose of the first information using the resources occupied by the first information, and the network device can determine the content indicated by the first information based on the resources occupied by the received first information. In this way, signaling overhead for the first information can be reduced.
[0027] In a possible implementation manner provided in the first aspect and / or the second aspect, the terminal device receives configuration information, and the terminal device determines the first resource based on the configuration information. The configuration information includes at least one of the following: information for indicating the first resource; information for indicating the resource of the reference signal, the resource of the reference signal including the resource occupied by the reference signal requested to be measured by the terminal device; information for indicating the second cell; information indicating the cell for sending the measurement result information; information indicating the resource for sending the measurement result information; and information indicating the cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs. The network device side can configure some information for the terminal device through the configuration information, and this information can be used by the terminal device to trigger the measurement of the reference signal and / or the sending process of the measurement result information. The terminal device can subsequently select from this information in the process of triggering the measurement of the reference signal and / or the sending process of the measurement result information.
[0028] In one possible implementation of the first and / or second aspects, the configuration information further includes information indicating an association between any of the following: the first resource, the second cell, a reference signal resource, a cell for transmitting measurement result information, a resource for transmitting measurement result information, and a cell to which the reference signal corresponding to the measurement result information requested by the terminal device belongs. In this manner, the terminal device can subsequently transmit one of the multiple associated pieces of information, allowing the network device to determine other pieces of information based on the one piece of information, thereby reducing signaling overhead.
[0029] In a possible implementation manner provided in the first aspect and / or the second aspect, the information for indicating the resources of the reference signal includes at least one of the following: information for indicating the trigger state; information for indicating the channel state information report configuration; index information of the synchronization signal block, the reference signal resource belongs to the resource associated with the index information of the synchronization signal block; an identifier of the reference signal resource; an identifier of the resource set corresponding to the reference signal resource; and an identifier of the resource configuration corresponding to the reference signal resource. Among them, the resources of the reference signal belong to the resources associated with the trigger state, the cell corresponding to the resources of the reference signal associated with the trigger state includes the second cell, and the cell corresponding to the trigger state is different from or the same as the second cell. The resources of the reference signal belong to the resources associated with the channel state information report configuration, the cell corresponding to the resources of the reference signal associated with the channel state information report configuration includes the second cell, and the cell corresponding to the channel state information report configuration is different from or the same as the second cell. This can improve the flexibility and compatibility of the solution.
[0030] In an embodiment of the present application, the above-mentioned information for indicating the resources of the reference signal may also indicate other information, and it can also be understood that the multiple information included in the above-mentioned configuration information may be the same information, and the multiple information included in the first information may be the same information. For example, the first information and / or the configuration information includes information for indicating the trigger state, and the information for indicating the trigger state can be understood as information for indicating the resources of the reference signal, and can also be understood as information for indicating the second cell. For another example, the first information and / or the configuration information includes information for indicating the channel state information report configuration, and the information for indicating the channel state information report configuration can be understood as information for indicating the resources of the reference signal, and can also be understood as information for indicating the second cell.
[0031] In a possible implementation provided by the first aspect and / or the second aspect, the terminal device may also receive third information through a fourth cell. The fourth cell is the same as or different from the first cell, and the fourth cell is the same as or different from the second cell. The third information is used to indicate successful or unsuccessful reception of the first information. Alternatively, the third information is used to: trigger the terminal device to measure the reference signal of the second cell, and / or trigger the terminal device to send measurement result information. In this solution, the terminal device may also receive the third information after sending the first information, and may then determine whether the content requested by itself through the first information is agreed to based on the third information. Alternatively, the terminal device determines, based on the third information, what information (or parameters) are associated with the measurement of the reference signal triggered by the terminal device and / or the sending process of the measurement result information.
[0032] In a possible implementation manner provided in the first aspect and / or the second aspect, the third information includes at least one of the following: information for indicating the second cell; information for indicating the trigger state; information for indicating the channel state information report configuration; information indicating the cell for sending the measurement result information; information indicating the resources for sending the measurement result information; information indicating the cell to which the reference signal corresponding to the measurement result information sent by the terminal device belongs. Among them, the cell corresponding to the resources of the reference signal associated with the trigger state includes the second cell, the cell corresponding to the trigger state is different from or the same as the second cell, and the cell corresponding to the trigger state is different from or the same as the fourth cell. The cell corresponding to the resources of the reference signal associated with the channel state information report configuration includes the second cell, the cell corresponding to the channel state information report configuration is different from or the same as the second cell, and the cell corresponding to the channel state information report configuration is different from or the same as the fourth cell. In this way, the terminal device can know what information is recommended by the network device side, and then consider using this information in subsequent processes.
[0033] In a possible implementation manner provided in the first aspect and / or the second aspect, the information used to indicate the trigger state includes: an identifier of the trigger state, and / or an identifier of the cell corresponding to the trigger state. This can improve the flexibility of the solution. For example, since the information used to indicate the trigger state also includes the cell corresponding to the trigger state, the cell that sends the information indicating the trigger state can be different from the cell corresponding to the trigger state. Subsequently, when the communication quality of the cell corresponding to the trigger state decreases, the present application can also improve the success rate of receiving the information indicating the trigger state.
[0034] In a possible implementation manner provided in the first aspect and / or the second aspect, the information used to indicate the channel state information report configuration includes: an identifier of the channel state information report configuration, and / or an identifier of the cell corresponding to the channel state information report configuration. This can improve the flexibility of the solution. For example, since the information used to indicate the channel state information report configuration also includes the cell corresponding to the channel state information report configuration, the cell that sends the information for indicating the channel state information report configuration may be different from the cell corresponding to the channel state information report configuration. Subsequently, when the communication quality of the cell corresponding to the channel state information report configuration decreases, the present application can also improve the success rate of receiving the information used to indicate the channel state information report configuration.
[0035] In a possible implementation provided by the first aspect and / or the second aspect, when the fourth cell is different from the cell corresponding to the trigger status and / or channel status information reporting configuration, the priority of the terminal device in sending the measurement result information is lower than: the measurement result information sending process associated with the trigger status information and / or channel status information reporting configuration corresponding to the fourth cell.
[0036] It can also be understood that the priority of sending the measurement result information associated with the trigger status and / or channel status information of other cells triggered by the terminal device through the fourth cell is lower than the priority of sending the measurement result information associated with the trigger status and / or channel status information of the fourth cell. It can also be understood that the priority of sending the measurement result information associated with the trigger status and / or channel status information of cross-cell scheduling by the terminal device is lower than the priority of sending the measurement result information associated with the trigger status and / or channel status information of the same cell scheduling. In this way, the sending of the measurement result information associated with the cross-cell scheduling will not cause significant interference to the sending of the measurement result information associated with the same cell scheduling.
[0037] In a possible implementation manner provided by the first aspect and / or the second aspect, when the first information is also used to indicate a process for sending measurement result information, the priority of the terminal device sending the measurement result information is lower than the measurement result information sending process triggered by the network device. The measurement result information sending process triggered by the network device may, for example, include a non-periodic and / or semi-continuous measurement result information sending process triggered by the network device. The priority of the terminal device sending the measurement result information is lower than the measurement result information sending process obtained by the terminal device periodically measuring a reference signal.
[0038] It can also be understood that the priority of sending measurement result information associated with the reference signal measurement and / or measurement result information sending process triggered by the terminal device is lower than the priority of sending measurement result information associated with the reference signal measurement and / or measurement result information sending process triggered by the network device. In this way, the sending of measurement result information triggered by the terminal device will not cause significant interference to the sending of measurement result information triggered by the network device.
[0039] In a third aspect, the present application provides a communication method, which is executed by a first network device, which may be a network device or a chip inside the network device.
[0040] In the method, a first network device receives first information via a first cell, the first information being used to indicate that a terminal device requests reference signal measurement of a second cell. The first network device determines based on the first information that the terminal device requests reference signal measurement of the second cell.
[0041] The above solution shows that the terminal device can trigger reference signal measurement using the first information. This means that the terminal device can trigger reference signal measurement without having to wait for the reference signal measurement process to be triggered by the network device. Specifically, the terminal device does not have to wait for the next reference signal measurement period to arrive before starting to measure the reference signal, nor does it have to wait for the network device to issue an instruction to trigger reference signal measurement. This can speed up the subsequent beam switching process and reduce the occurrence of communication interruptions.
[0042] The relevant content of the first information and the information included in the first information, as well as other descriptions and beneficial effects can be found in the relevant descriptions of possible implementation methods of the first and second aspects mentioned above, and will not be repeated here.
[0043] In a fourth aspect, the present application provides a communication method, which is executed by a first network device, which may be a network device or a chip inside the network device.
[0044] In this method, a first network device receives first information via a first cell, the first information being used to indicate a request from a terminal device to transmit measurement result information. The first network device determines, based on the first information, that the terminal device requests transmission of measurement result information. The first information in the fourth aspect and the first information in the third aspect may be two different pieces of first information, or the same piece of first information.
[0045] As can be seen from the above solution, the terminal device can trigger the transmission of measurement result information using the first information. In other words, the terminal device can trigger the transmission of measurement result information without having to wait for the transmission of measurement result information triggered by the network device. The measurement result information included in the second information may include measurement result information obtained during a reference signal measurement process triggered by the network device and / or the terminal device.
[0046] The relevant content of the first information and the information included in the first information, as well as other descriptions and beneficial effects can be found in the relevant descriptions of possible implementation methods of the first and second aspects mentioned above, and will not be repeated here.
[0047] In a fifth aspect, the present application provides a communication method. The method is performed by a second network device, which can be a network device or a chip inside the network device. The second network device can be the same as or different from the first network device.
[0048] In this solution, the second network device receives a second information transmission reference signal through a second cell.
[0049] The cell in which the terminal device sends the first information and the cell in which the reference signal is measured may be the same or different, so that the terminal device may trigger the measurement of the reference signal of the same cell or trigger the measurement of the reference signal across cells.
[0050] The relevant content of the second information, as well as other descriptions and beneficial effects can be found in the relevant descriptions of possible implementation methods of the first and second aspects mentioned above, and will not be repeated here.
[0051] In a sixth aspect, the present application provides a communication method. The method is performed by a third network device, which may be a network device or a chip within the network device. The third network device may be the same as or different from the first network device. The third network device may be the same as or different from the fifth network device. The third network device may be the same as or different from the fourth network device.
[0052] In this solution, the third network device receives the second information through the third cell.
[0053] The second information may include measurement results. The cell used to send the measurement results can be individually configured. For example, a cell with a low load or a cell with high communication quality can be configured to send the measurement results. This can improve the success rate of measurement result reception and balance network load.
[0054] The relevant content of the second information, as well as other descriptions and beneficial effects can be found in the relevant descriptions of possible implementation methods of the first and second aspects mentioned above, and will not be repeated here.
[0055] In a seventh aspect, the present application provides a communication method. The method is performed by a fourth network device, which can be a network device or a chip within the network device. The fourth network device can be the same as or different from the first network device. The fourth network device can be the same as or different from the fifth network device.
[0056] In this solution, the fourth network device sends the third information through the fourth cell.
[0057] During the process of transmitting the reference signal measurement and / or measurement result information triggered by the terminal device, the fourth network device may also transmit information via the fourth cell to indicate information required by the terminal device for subsequent processes. For example, the terminal device determines whether the content requested by the terminal device through the first information is approved based on the third information. Alternatively, the terminal device determines, based on the third information, the information (or parameters) associated with the process of transmitting the reference signal measurement and / or measurement result information triggered by the terminal device.
[0058] The relevant content of the third information, as well as other descriptions and beneficial effects can be found in the relevant descriptions of possible implementation methods of the first and second aspects mentioned above, and will not be repeated here.
[0059] In an eighth aspect, the present application provides a communication method. The method is performed by a fifth network device, which may be a network device or a chip within the network device. The fifth network device may be the same as or different from the first network device.
[0060] In the method, the fifth network device sends configuration information.
[0061] The fifth network device may configure certain information for the terminal device through configuration information. This information may be used by the terminal device to trigger reference signal measurement and / or transmit measurement result information. The terminal device may subsequently select from this information during the process of triggering reference signal measurement and / or transmitting measurement result information.
[0062] The relevant content of the configuration information, as well as other descriptions and beneficial effects can be found in the relevant descriptions of possible implementation methods of the first and second aspects mentioned above, and will not be repeated here.

[0088] Before introducing the present application, some of the terms used in the embodiments of the present application are briefly explained to facilitate understanding by those skilled in the art.
[0089] (1) Reference signal.
[0090] The reference signal in the embodiment of the present application may include (or be) any one or more of a channel state information (CSI) reference signal (RS) (the channel state information reference signal may also be denoted as CSI-RS), a synchronization signal block (SSB), a synchronization signal / physical broadcast channel block (SS / PBCH block), a demodulation reference signal (DMRS), a tracking reference signal (TRS), a phase tracking reference signal (PTRS), a cell reference signal (CRS) and a sounding reference signal (SRS). In the embodiment of the present application, the SSB and the SS / PBCH block may be replaced with each other.
[0091] (2) Resources.
[0092] The protocol does not directly use the term "beam" to represent a beam. Instead, other methods are used to implicitly describe beam-related operations. For example, in beam measurement, there is a corresponding relationship between beams and resources (the network device uses a beam to transmit its corresponding resource). When a terminal device measures the quality of the resource, it is equivalent to measuring the quality of the beam. The resources in the embodiments of the present application may include, for example, reference signal resources.
[0093] The resources in the embodiments of the present application may include at least one of time domain resources or frequency domain resources.
[0094] Time domain resources may include at least one of a radio frame, a subframe, a time slot, a mini slot, or an orthogonal frequency division multiplexing (OFDM) symbol. A radio frame may include multiple subframes, a subframe may include one or more time slots, and a time slot may include at least one symbol. Alternatively, a radio frame may include multiple time slots, and a time slot may include at least one symbol. It should be noted that in the embodiments of the present application, an OFDM symbol may also be referred to as a symbol.
[0095] Frequency domain resources may include at least one of a resource element (RE), a resource block (RB), a channel, a subchannel, a carrier, or a bandwidth part (BWP). In this embodiment of the present application, a channel may be equivalently replaced by a resource block set (RB set), and the frequency domain bandwidth of an RB set may be 20 megahertz (MHz).
[0096] (3) Beam.
[0097] The embodiment of beamforming in the new radio (NR) protocol can be a spatial domain filter, also known as a spatial filter, or also known as a spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, or quasi-colocation (QCL) information, QCL assumption, QCL indication, etc. The beamforming can be indicated by the transmission configuration indicator state (TCI-state) parameter or by the spatial relation parameter.
[0098] Therefore, in this application, beam can be replaced by spatial filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI-state (downlink TCI-state, uplink TCI-state), spatial relationship, etc. The above terms are also equivalent to each other. Beam can also be replaced by other terms representing beams, which are not limited in this application.
[0099] In the embodiment of the present application, any two of the downlink beam, CSI-RS, TCI-state, downlink / joint TCI state (DL or joint TCI state), SSB, and tracking reference signal (TRS) can be replaced with each other.
[0100] The beam used to transmit a signal may be referred to as a transmission beam (Tx beam), or may be referred to as a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, or a spatial transmission parameter, or a spatial domain transmission setting. The downlink transmit beam may be indicated by a TCI-state.
[0101] In the embodiment of the present application, any two of the uplink beam, uplink (UL) TCI state, DL or joint TCI state, SRS, CSI-RS, SSB and TRS can be replaced with each other.
[0102] The beam used to receive signals can be called a reception beam (Rx beam), and can also be called a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, or a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting. The uplink transmit beam can be indicated by a spatial relationship, an uplink TCI-state, or an SRS resource (indicating the transmit beam using the SRS). Therefore, the uplink beam can also be replaced by an SRS resource.
[0103] The transmit beam may refer to the distribution of signal strength in different directions in space after the signal is transmitted by the antenna, and the receive beam may refer to the distribution of signal strength in different directions in space of the wireless signal received from the antenna.
[0104] Furthermore, the beam can be a wide beam, a narrow beam, or other types of beams. The beam forming technology can be beamforming technology or other technologies. The beamforming technology can specifically be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology.
[0105] Beams are generally associated with resources. For example, during beam measurement, network equipment uses different resources to measure different beams. The terminal device then provides feedback on the measured resource quality, allowing the network equipment to determine the quality of the associated beam. During data transmission, beam information is also indicated by its associated resources. For example, the network equipment uses the TCI field in the downlink control information (DCI) to indicate physical downlink shared channel (PDSCH) beam information to the terminal device.
[0106] Optionally, multiple beams with the same or similar communication characteristics can be considered a single beam. A beam can include one or more antenna ports for transmitting data channels, control channels, and sounding signals. The one or more antenna ports forming a beam can also be considered an antenna port set.
[0107] In the embodiments of the present application, unless otherwise specified, a beam refers to a transmission beam of a network device. In beam measurement, each beam of a network device is associated with a resource, so the resource index can be used to uniquely identify the beam associated with the resource.
[0108] (4)TCI-state (used to indicate the downlink beam).
[0109] Network devices can generate different beams pointing in different transmission directions. During downlink data transmission, when a network device uses a specific beam to send data to a terminal device, it must inform the terminal device of the transmit beam information it uses. This allows the terminal device to use the receive beam associated with that transmit beam to receive the data sent by the network device.
[0110] In the 3GPP R15 / R16 protocol, the network device uses the TCI field in the DCI to indicate to the terminal device the relevant information of the transmission beam it adopts. Specifically, the TCI field size is 3 bits, which can specifically represent 8 different field values (codepoints). Each value of the TCI field is associated with a TCI-state index, and the TCI-state index can uniquely identify a TCI-state. The TCI-state in the embodiment of the present application can also be written as TCI state. TCI-state includes several parameters, and the relevant information of the transmission beam can be determined by these parameters. TCI-state is configured by the network device to each terminal device, and the structure of TCI-state is shown in Figure 1. Each TCI-state includes its own index TCI-state identifier, and two QCL information (QCL information, QCL-Info). Each QCL-Info includes a cell field and a bandwidth (bandwidth part, bwp) identifier, which respectively indicate which bandwidth of which cell the TCI-state is applied to, that is, different cells or different bandwidths of the same cell can be configured with different QCL-Info. QCL-Info also includes a reference signal, which is used to indicate which reference signal resource constitutes the QCL relationship.
[0111] In the R15 / R16 protocols, the word "beam" generally does not appear directly; it is usually replaced by other terms. For example, in data transmission and channel measurement, beams are associated with reference signal resources, with one beam associated with one reference signal resource. Therefore, when we say which reference signal resource forms a QCL relationship, we are actually referring to which beam forms a QCL relationship. A QCL relationship means that two reference signal resources (or two antenna ports, where antenna ports and reference signal resources are also associated one-to-one) have certain identical spatial parameters. Which spatial parameters are identical depends on the type of the QCL-Info, i.e., another field of the QCL-Info, qcl-Type. qcl-Type can have four values {typeA, typeB, typeC, typeD}. Taking typeD as an example, typeD indicates that the two reference signal resources have the same spatial reception parameter information, i.e., the two beams have the same receive beam. At most one of the two QCL-Info included in the TCI-state can be TypeD.
[0112] (5) Spatial relation (used to indicate uplink beam).
[0113] In the current protocol, the transmit beam for uplink transmission is indicated by spatial relationships, which functions similarly to TCI-state, and is used to inform the terminal device which transmit beam to use for uplink transmission.
[0114] The spatial relationship also needs to be configured through radio resource control (RRC) signaling first. RRC signaling may include the identification (ID) of the spatial relationship, cell ID, target reference signal resource, path loss measurement reference signal, power control parameters, etc. Among them, the target reference signal resource (which may be one of SRS / SSB / CSI-RS) is used to indicate the associated uplink beam. If the uplink transmission adopts spatial relationship #1, and the spatial relationship #1 includes a target reference signal resource #2, it means that the transmission beam used for the uplink transmission is the transmission / reception beam of the target reference signal. For example, when the target reference signal resource is the uplink resource SRS, it means that the transmission beam used for the uplink transmission is the transmission beam of the SRS (the transmission beam of the SRS is known). For another example, the target reference signal resource is a downlink resource such as SSB / CSI-RS, which means that the transmission beam used for the uplink transmission is the reception beam of the SSB / CSI-RS (the reception beam of the SSB / CSI-RS is known).
[0115] The network device can configure multiple spatial relationships for the terminal device. Then one of them is activated for associated data transmission through the media access control control element (MAC CE). Uplink transmission includes the physical uplink control channel (PUCCH), SRS, physical uplink shared channel (PUSCH), etc., all of which require associated spatial relationships. The spatial relationship of PUCCH is indicated by MAC CE signaling. The spatial relationship of SRS is also indicated by MAC CE signaling. When PUSCH is transmitted, it will be associated with a specific SRS and use the spatial relationship of the SRS for transmission.
[0116] Figure 1 exemplarily shows an architectural diagram of a communication system 1000 applicable to an embodiment of the present application. As shown in Figure 1, Figure 1 is a schematic diagram of the architecture of the communication system 1000 applicable to an embodiment of the present application. As shown in Figure 1, the communication system includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet 300. The RAN 100 includes at least one RAN node (such as 110a and 110b in Figure 1, collectively referred to as 110), and may also include at least one terminal (such as 120a-120j in Figure 1, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). The terminal 120 is connected to the RAN node 110 via a wireless method, and the RAN node 110 is connected to the core network 200 via a wireless or wired method. The core network devices in the core network 200 and the RAN nodes 110 in the RAN 100 may be independent and distinct physical devices, or they may be a single physical device that integrates the logical functions of the core network devices and the logical functions of the RAN nodes. Terminals and RAN nodes may be connected to each other via wired or wireless means.
[0117] RAN100 may be an evolved universal terrestrial radio access (E-UTRA) system, a NR system, or a future radio access system defined in the 3rd Generation Partnership Project (3GPP). RAN100 may also include two or more of the aforementioned different radio access systems. RAN100 may also be an open RAN (O-RAN).
[0118] The network equipment involved in the embodiments of the present application may be a RAN node. A RAN node, also known as a radio access network device, a RAN entity or an access node, is used to help a terminal access a communication system wirelessly. In one application scenario, a RAN node may be a base station, an evolved NodeB (eNodeB), a TRP, a next generation NodeB (gNB) in a fifth generation (5G) mobile communication system, a next generation base station in a sixth generation (6G) mobile communication system, or a base station in a future mobile communication system. A RAN node may be a macro base station (such as 110a in FIG1 ), a micro base station or an indoor station (such as 110b in FIG1 ), or a relay node or a donor node.
[0119] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing portions of the base station's functions. For example, a RAN node can be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The CU implements the base station's radio resource control protocol and packet data convergence protocol (PDCP) functions, as well as the service data adaptation protocol (SDAP) functions. The DU implements the base station's radio link control layer and medium access control (MAC) layer functions, as well as some or all of the physical layer functions. For detailed descriptions of each of the above protocol layers, please refer to the relevant 3GPP technical specifications. The RU can be used to implement the transmission and reception of radio frequency signals. The CU and DU can be two independent RAN nodes, or they can be integrated into the same RAN node, such as in a baseband unit (BBU). The RU can be included in radio frequency equipment, such as a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.
[0120] In different systems, RAN nodes may have different names. For example, in an O-RAN system, CU may be called an open CU (open CU, O-CU), DU may be called an open DU (open DU, O-DU), and RU may be called an open RU (open RU, O-RU). The centralized unit control plane (central unit control panel, CU-CP) may also be called an open centralized unit control plane (open CU-CP, O-CU-CP), and the centralized unit user plane (central unit user panel, CU-UP) may also be called an open centralized unit user plane (open CU-UP, O-CU-UP). The RAN node in the embodiments of the present application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. For example, the RAN node may be a server loaded with the corresponding software module. The embodiments of the present application do not limit the specific technology and specific device form adopted by the RAN node. For the convenience of description, the following description takes a base station as an example of a RAN node.
[0121] A terminal is a device with wireless transceiver capabilities that can send signals to a base station or receive signals from a base station. A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the terminal.
[0122] Base stations and terminals can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.
[0123] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. To terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station. However, to base station 110a, 120i is a terminal, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with base station functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal functionality.
[0124] Communication between base stations and terminals, between base stations, and between terminals can be carried out through authorized spectrum, unauthorized spectrum, or both. Communication can be carried out through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.
[0125] In the embodiments of the present application, the functions of the base station may also be performed by a module (such as a chip) in the base station, or by a control subsystem that includes the base station functions. The control subsystem that includes the base station functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal may also be performed by a module (such as a chip or modem) in the terminal, or by a device that includes the terminal functions.
[0126] In this application, a base station sends downlink signals or downlink information to a terminal, and the downlink information is carried on a downlink channel; the terminal sends uplink signals or uplink information to the base station, and the uplink information is carried on an uplink channel. In order to communicate with the base station, the terminal needs to establish a wireless connection with the cell controlled by the base station. The cell with which the terminal has established a wireless connection is called the serving cell of the terminal. When the terminal communicates with the serving cell, it will also be subject to interference from signals in neighboring cells.
[0127] The communication between the access network device and the terminal device may follow a certain protocol layer structure. Exemplarily, the protocol layer structure may include a control plane protocol layer structure and a user plane protocol layer structure. For example, the control plane protocol layer structure may include at least one of the following: a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a media access control (MAC) layer, or a physical (PHY) layer. For example, the user plane protocol layer structure may include at least one of the following: a service data adaptation protocol (SDAP) layer, a PDCP layer, an RLC layer, a MAC layer, or a physical layer.
[0128] The access network equipment may include a central unit (CU) and a distributed unit (DU). This design may be referred to as CU and DU separation. Multiple DUs may be centrally controlled by one CU. As an example, the interface between the CU and the DU is referred to as the F1 interface. Among them, the control plane (CP) interface may be F1-C, and the user plane (UP) interface may be F1-U. The embodiments of the present application do not limit the specific names of the interfaces. The CU and the DU may be divided according to the protocol layers of the wireless network: for example, the functions of the PDCP layer and the protocol layers above (such as the RRC layer and the SDAP layer, etc.) are set in the CU, and the functions of the protocol layers below the PDCP layer (such as the RLC layer, the MAC layer and the PHY layer, etc.) are set in the DU; for another example, the functions of the protocol layers above the PDCP layer are set in the CU, and the functions of the protocol layers below the PDCP layer are set in the DU, without limitation.
[0129] The above division of the processing functions of CU and DU according to the protocol layer is only an example, and they can also be divided in other ways. For example, the CU or DU can be divided into functions with more protocol layers, and the CU or DU can be divided into partial processing functions with protocol layers. For example, some functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU. For another example, the functions of the CU or DU can be divided according to the service type or other system requirements, such as division by delay, and the functions whose processing time needs to meet the delay requirements are set in the DU, and the functions that do not need to meet the delay requirements are set in the CU.
[0130] Optionally, the CU may have one or more functions of the core network.
[0131] Optionally, the radio unit (RU) of the DU can be remotely located. The RU has radio frequency functions. Exemplarily, the DU and RU can be divided at the PHY layer. For example, the DU can implement high-layer functions in the PHY layer, and the RU can implement low-layer functions in the PHY layer. When used for transmission, the functions of the PHY layer may include at least one of the following: adding cyclic redundancy check (CRC) bits, channel coding, rate matching, scrambling, modulation, layer mapping, precoding, resource mapping, physical antenna mapping, or radio frequency transmission functions. When used for reception, the functions of the PHY layer may include at least one of the following: CRC check, channel decoding, rate matching, descrambling, demodulation, layer demapping, channel detection, resource demapping, physical antenna demapping, or radio frequency reception functions. The high-layer functions in the PHY layer may include a portion of the functions of the PHY layer, which is closer to the MAC layer; the low-layer functions in the PHY layer may include another portion of the functions of the PHY layer, such as a portion closer to the radio frequency functions. For example, the high-level functions in the PHY layer may include adding CRC bits, channel coding, rate matching, scrambling, modulation, and layer mapping, and the low-level functions in the PHY layer may include precoding, resource mapping, physical antenna mapping, and radio frequency transmission functions; or, the high-level functions in the PHY layer may include adding CRC bits, channel coding, rate matching, scrambling, modulation, layer mapping, and precoding, and the low-level functions in the PHY layer may include resource mapping, physical antenna mapping, and radio frequency transmission functions. For example, the high-level functions in the PHY layer may include CRC checking, channel decoding, rate matching, decoding, demodulation, and layer matching, and the low-level functions in the PHY layer may include channel detection, resource demapping, physical antenna demapping, and radio frequency reception functions; or, the high-level functions in the PHY layer may include CRC checking, channel decoding, rate matching, decoding, demodulation, layer matching, and channel detection, and the low-level functions in the PHY layer may include resource demapping, physical antenna demapping, and radio frequency reception functions.
[0132] Optionally, the functions of the CU can be further divided, and the control plane and the user plane can be separated and implemented through different entities. The separated entities are the control plane CU entity (i.e., CU-CP entity) and the user plane CU entity (i.e., CU-UP entity). The CU-CP entity and the CU-UP entity can be connected to the DU respectively. In the embodiment of the present application, the entity can be understood as a module or a unit, and its existence can be a hardware structure, a software module, or a hardware structure plus a software module, without limitation.
[0133] Optionally, any one of the above-mentioned CU, CU-CP, CU-UP, DU and RU can be a software module, a hardware structure, or a software module plus a hardware structure, without limitation. The existence forms of different entities can be the same or different. For example, CU, CU-CP, CU-UP and DU are software modules, and RU is a hardware structure. For the sake of brevity, all possible combinations are no longer listed here. These modules and their execution methods are also within the scope of protection of the embodiments of the present application. For example, when the method of the embodiment of the present application is executed by an access network device, it can be specifically executed by at least one of CU, CU-CP, CU-UP or DU.
[0134] Based on the embodiment shown in FIG1 , FIG2A exemplarily shows a possible flow diagram of a communication method provided in an embodiment of the present application. The terminal device in FIG2A may be the terminal device shown in FIG1 above or a chip inside the terminal device, and the first network device and / or the second network device in FIG2A may be the network device (such as a RAN node, such as a CU or DU) or a chip in a network device (such as a chip in a RAN node, such as a chip in a CU or DU) in FIG1 above.
[0135] As shown in Figure 2A, the method includes step 201, step 202, and step 203. The following is an introduction with reference to Figure 2A.
[0136] Step 201: The terminal device sends first information through a first cell.
[0137] Correspondingly, the first network device receives the first information through the first cell.
[0138] The first information is used to indicate that the terminal device requests reference signal measurement. In the embodiment of the present application, "the terminal device requests reference signal measurement" can be replaced with "the terminal device triggers reference signal measurement" or "the terminal device initiates reference signal measurement". For example, the terminal device may request measurement of a cell (such as the second cell). In this case, it can also be understood that the first information is used to indicate that the terminal device requests reference signal measurement of the second cell.
[0139] Step 202: A second network device sends at least one reference signal via a second cell.
[0140] Correspondingly, the terminal device receives at least one reference signal through the second cell.
[0141] In an embodiment of the present application, the first cell and the second cell may be different or the same, so that the flexibility of the solution can be improved. In one possible implementation, when the terminal device determines that the second cell needs to measure the reference signal, the current beam quality of the second cell may be poor. In this case, if the terminal device still sends information for requesting measurement of the reference signal of the second cell through the second cell, the second network device may not receive the information, which in turn causes the reference signal measurement process requested by the terminal device to fail. In a solution provided by an embodiment of the present application, the first cell may be different from the second cell, that is, the information sent by the terminal device for requesting measurement of the reference signal of the second cell may not be the second cell, thereby improving the success rate of the terminal device's request for reference signal measurement this time.
[0142] The fourth cell and the third cell will be mentioned later in the embodiment of the present application. Any two of the first cell, the second cell, the fourth cell and the third cell in the embodiment of the present application may be the same or different.
[0143] In the embodiment of the present application, the first network device may be a network device corresponding to the first cell. In the embodiment of the present application, the second network device may be a network device corresponding to the second cell. In the embodiment of the present application, the first network device and the second network device may be the same or different. For example, the first network device and the second network device are the same, and the first cell and the second cell are different. For example, the first cell and the second cell are two component carriers (CCs) under the first network device.
[0144] In the embodiments of the present application, a third network device, a fourth network device, and a fifth network device will be involved later. The third network device may be a network device corresponding to the third cell, and the fourth network device may be a network device corresponding to the fourth cell. In the embodiments of the present application, a cell corresponding to any network device can be understood as the network device providing services for the cell, or as belonging to the signal coverage range of the network device. For example, the first network device can provide services for the first cell, the second network device can provide services for the second cell, the third network device can provide services for the third cell, and the fourth network device can provide services for the fourth cell. A network device (such as the first network device, the second network device, the fourth network device, the third network device, or the fifth network device) can correspond to one or more cells.
[0145] In the embodiment of the present application, any one of the first cell, the second cell, the third cell and the fourth cell may be, for example, a serving cell, a neighboring cell of the serving cell (such as a cell corresponding to an additional PCI). Alternatively, any one of the first cell, the second cell, the third cell and the fourth cell may be, for example, a primary cell (Pcell), a secondary cell (Scell), or a primary secondary cell (PScell). In the embodiment of the present application, any one of the first cell, the second cell, the third cell and the fourth cell may be replaced by a candidate cell, such as a cell corresponding to a layer (L) 1 / layer 2 triggered mobility (L1 / L2-triggered mobility, LTM)-candidate ID.
[0146] In the embodiment of the present application, the cell of the primary component carrier (PCC) may be referred to as a Pcell, and the cell of the secondary component carrier (SCC) may be referred to as an Scell. In the inter-cell multiple transmission reception point (inter-cell mTRP) scenario, the serving cell and the non-serving cell are associated with different physical cell identifiers (PCIs). To distinguish them, the PCI of the non-serving cell may be referred to as an additional PCI.
[0147] In the embodiment of the present application, any two of the first network device, the second network device, the fourth network device, the third network device, and the fifth network device may be the same or different. When the two network devices are the same, the two cells corresponding to the two network devices may also be different or the same. In the embodiment of the present application, any two of the first network device, the second network device, the fourth network device, the third network device, and the fifth network device may be located in two different physical devices, or in the same physical device. In the case where any two of the first network device, the second network device, the fourth network device, and the third network device in the embodiment of the present application are located in the same physical device, the two network devices may also be two different network devices or the same network device. For example, any two of the first network device, the second network device, the fourth network device, the third network device, and the fifth network device may correspond to two CCs under the same base station.
[0148] Step 203: The terminal device measures at least one reference signal to obtain at least one measurement result information.
[0149] The measurement result information in the embodiment of the present application may be replaced by the measurement result information, or may be replaced by any one or more information included in the measurement result information, such as channel state information (CSI). The measurement result information may include any one or more of reference signal receiving power (RSRP) (RSRP may also be referred to as layer 1 reference signal received power (L1-RSRP)), signal to interference plus noise ratio (SINR) (SINR may be referred to as layer 1 signal to interference plus noise ratio (L1-SINR)), channel quality indicator (CQI), precoding matrix indicator (PMI), CSI-RS resource indicator (CSI-RS resource indicator, CRI), SSB resource indicator (SS / PBCH block resource indicator, SSBRI), layer indicator (LI), and rank indicator (RI).
[0150] As can be seen from the solution provided in Figure 2A, the terminal device can trigger reference signal measurement using the first information. This means that the terminal device can trigger reference signal measurement without having to wait for the reference signal measurement process to be triggered by the network device. Specifically, the terminal device does not have to wait for the next reference signal measurement period to arrive before starting to measure the reference signal, nor does it have to wait for the network device to issue an instruction to trigger reference signal measurement. This can speed up the subsequent beam switching process and reduce the occurrence of communication interruptions.
[0151] For example, when the channel quality changes and the terminal device discovers that the quality of the current serving beam has deteriorated, the terminal device can proactively send information requesting reference signal measurement, without having to wait for the next reference signal measurement cycle to arrive before starting to measure the reference signal, or without having to wait for the network device to issue an instruction for triggering the reference signal measurement. In the solution provided in the embodiment of the present application, precisely because the terminal device can trigger the measurement of the reference signal, the solution can accelerate the subsequent beam switching process and thereby reduce the occurrence of communication interruptions.
[0152] In one possible implementation provided in FIG2A , the terminal device determines a cell to which the terminal device transmits measurement result information, where the cell to which the terminal device transmits the measurement result information includes a third cell. The terminal device transmits the second information via the third cell. In the implementation provided in FIG2A , the second information may include (or may not include) part or all of the at least one measurement result information obtained by the terminal device in step 203.
[0153] In another possible implementation, the second information may further include (or exclude) measurement result information obtained from the measurement of a reference signal that is not triggered by the terminal device. The measurement result information obtained from the measurement of a reference signal that is not triggered by the terminal device includes, for example, measurement result information obtained in a measurement process of a reference signal triggered by a network device, and / or measurement result information obtained by the terminal device periodically measuring a reference signal.
[0154] The reference signal measurement process triggered by a network device in the present application can be understood as follows: in the reference signal measurement scheme of an AP or SP, when the network device determines that reference signal measurement is required, the network device sends signaling to a terminal device for triggering reference signal measurement. Upon receipt of the signaling, the terminal device begins reference signal measurement and obtains measurement result information. This measurement result information can also be understood as measurement result information obtained in the reference signal measurement process triggered by the network device.
[0155] The measurement result information obtained by the terminal device of the present application periodically measuring the reference signal can be understood as: information such as the resources of the reference signal configured by the network device for the terminal device to measure. In the periodic reference signal measurement scheme, the terminal device can measure the reference signal based on the resources configured by the network device and other information when the measurement time arrives within each period to obtain measurement result information. This measurement result information can also be understood as measurement result information obtained by the terminal device periodically measuring the reference signal.
[0156] In one possible implementation, the first information indicates that the terminal device requests measurement of a reference signal of the second cell (for example, the first information may include information for indicating that the terminal device requests measurement of a reference signal of the second cell). This implementation may also be understood as: the first information is used to indicate information that the terminal device requests measurement of a reference signal of the second cell, but does not indicate that the terminal device requests sending the measurement result of the reference signal of the second cell. In this case, the terminal device may trigger measurement of the reference signal (for example, subsequently measuring the reference signal), and the terminal device does not trigger sending of measurement result information (for example, not sending measurement result information); or, the terminal device may trigger measurement of the reference signal (for example, subsequently measuring the reference signal), and the terminal device also triggers sending of measurement result information (for example, sending the second information).
[0157] In another possible implementation, the first information is also used to indicate that the terminal device requests to send the measurement result of the reference signal of the second cell (for example, the first information may also include information used to indicate that the terminal device requests to send the measurement result of the reference signal of the second cell). In this case, the terminal device can trigger the measurement of the reference signal (for example, subsequently measure the reference signal), and the terminal device also triggers the sending of measurement result information (for example, sending the second information).
[0158] Based on the embodiments shown in Figures 1 and 2A, Figure 2B exemplarily shows a possible flow chart of a communication method provided in an embodiment of the present application. The third network device in Figure 2B can be the network device (such as a RAN node, such as a CU or DU) or a chip in the network device (such as a chip in a RAN node, such as a chip in a CU or DU) in Figure 1. The relevant description of the terminal device, the first network device, and the third network device in Figure 2B can be referred to the relevant description in Figure 2A and will not be repeated here.
[0159] As shown in Figure 2B, the method includes step 211, step 212, and step 213. The following is an introduction with reference to Figure 2B.
[0160] Step 211: The terminal device sends first information through the first cell.
[0161] Correspondingly, the first network device receives the first information through the first cell.
[0162] The first information is used to indicate that the terminal device requests to send measurement result information. In the embodiments of the present application, "the terminal device requests to send measurement result information" can be replaced with "the terminal device triggers the sending of measurement result information", or with "the terminal device triggers the reporting of measurement result information", or with "the terminal device initiates the sending of measurement result information", or with "the terminal device initiates the reporting of measurement result information". In the embodiments of the present application, "report" and "send" can be used interchangeably.
[0163] Step 212: The terminal device sends second information via the third cell.
[0164] Correspondingly, the third network device receives the second information through the third cell.
[0165] The second information includes at least one piece of measurement result information.
[0166] In the embodiment of the present application, the third cell and the first cell may be different or the same, which can improve the flexibility of the solution.
[0167] As shown in the solution provided in Figure 2B, the terminal device can trigger the transmission of measurement result information using the first information. This means that the terminal device can trigger the transmission of measurement result information without having to wait for the network device to trigger the transmission of measurement result information. Specifically, the terminal device does not have to wait for the next measurement result information transmission period to arrive before starting to transmit measurement result information, nor does it have to wait for the network device to issue an instruction to trigger the transmission of measurement result information. This can speed up the subsequent beam switching process and reduce the occurrence of communication interruptions.
[0168] For example, when the channel quality changes and the terminal device discovers that the quality of the current serving beam has deteriorated, the terminal device can proactively send a request to send measurement result information, without having to wait for the next reference signal measurement period to arrive before starting to send the measurement result information, or without having to wait for the network device to issue an instruction to trigger the transmission of the measurement result information. In the solution provided in the embodiment of the present application, precisely because the terminal device can trigger the transmission of the measurement result information, the solution can accelerate the subsequent beam switching process and thereby reduce the occurrence of communication interruptions.
[0169] The "transmission of measurement result information triggered by a terminal device" involved in the embodiments of the present application may also be referred to as the "transmission process of measurement result information triggered by the terminal device," specifically referring to the terminal device sending first information, where the first information is at least used to request the transmission of measurement result information. The "transmission of measurement result information triggered by a network device" also involved in the embodiments of the present application may also be referred to as the "transmission process of measurement result information triggered by a network device," specifically referring to the network device first sending information to the terminal device that instructs the terminal device to send the measurement result information.
[0170] In an embodiment of the present application, the priority of the terminal device in sending the measurement result information is lower than the measurement result information sending process triggered by the network device. The measurement result information sending process triggered by the network device may, for example, include a non-periodic and / or semi-continuous measurement result information sending process triggered by the network device. The priority of the terminal device in sending the measurement result information may also be lower than the sending process of the measurement result information obtained by the terminal device periodically measuring the reference signal. In this way, the sending of the measurement result information triggered by the terminal device will not cause significant interference to the sending of the measurement result information triggered by the network device.
[0171] For example, when the measurement result information report triggered by the terminal device overlaps with the measurement result information report triggered by the non-terminal device (the measurement result information report triggered by the non-terminal device includes, for example: the measurement result information report triggered by the network device or the periodic measurement result information report of the terminal device) on at least one OFDM symbol in the time domain of the same subcarrier, then the measurement result information report triggered by the terminal device is lower than the measurement result information report triggered by the non-terminal device, and the reporting is multiplexed according to the priority rule or the terminal device discards the measurement result information triggered by the terminal device (that is, not reporting). In one possible implementation, the reporting of the measurement result information has the following priority rules: Pri iCSI (x, y, k, c, s) = 3·N cells ·M s ·x+2·N cells ·M s y+N cells ·M s k+M s c+s
[0172] Wherein, x=0 indicates measurement result information reporting triggered by a network device or periodic measurement result information reporting by a terminal device; x=1 indicates measurement result information reporting triggered by a terminal device;
[0173] y=0 indicates aperiodic CSI reporting carried by PUSCH, y=1 indicates semi-persistent CSI reporting carried by PUSCH, y=2 indicates semi-persistent CSI reporting carried by PUCCH, and y=3 indicates periodic CSI reporting carried by PUCCH;
[0174] k=0 indicates that the CSI report of L1-RSRP or L1-SINR is carried, and k=1 indicates that the CSI report of L1-RSRP or L1-SINR is not carried;
[0175] c represents the serving cell index;
[0176] N cellsIndicates the maximum number of serving cells configured by a higher-level parameter (the higher-level parameter may be maxNrofServingCells);
[0177] s is the report configuration identifier (the report configuration identifier can be recorded as reportConfigID);
[0178] M s Indicates the maximum number of CSI report configurations configured by a higher-level parameter (the higher-level parameter may be maxNrofCSI-ReportConfigurations);
[0179] Pri iCSI (x, y, k, c, s) represents the priority, where Pri iCSI The smaller the (x,y,k,c,s) value is, the higher the priority can be.
[0180] In the embodiment provided in FIG2B , the first information sent by the terminal device in step 211 and the first information sent by the terminal device in step 201 may be the same first information or two different first information. The first information in step 201 may also be replaced by information indicating that the terminal device requests measurement of a reference signal. The first information in step 211 may also be replaced by information indicating that the terminal device requests transmission of measurement result information.
[0181] The embodiments shown in FIG2A and FIG2B can be executed separately, that is, the terminal device can independently trigger the measurement of the reference signal, and after obtaining the measurement result information, can send the measurement result information or not. The terminal device can also independently trigger the sending of measurement result information, and the measurement result information sent by the terminal device can be obtained by measuring the reference signal before. The measurement of these reference signals can include the measurement of the reference signal triggered by the terminal device and / or the measurement of the reference signal triggered by the network device.
[0182] In another possible implementation, the solutions provided in Figures 2A and 2B can be used in combination. Based on the embodiments shown in Figures 1, 2A, and 2B, Figure 2C exemplarily illustrates a possible flow diagram of a communication method provided in an embodiment of the present application. Figure 2C can be regarded as an embodiment of the combined use of Figures 2A and 2B. The relevant description of the terminal device, the first network device, the second network device, and the third network device in Figure 2C can be found in the relevant description in Figures 2A or 2B above, and will not be repeated here.
[0183] As shown in Figure 2C, the method includes step 201, step 202, and step 203. The following is an introduction with reference to Figure 2A.
[0184] Step 221 : The terminal device sends information through the first cell indicating that the terminal device requests measurement of a reference signal.
[0185] Correspondingly, the first network device receives, through the first cell, information indicating that the terminal device requests measurement of the reference signal.
[0186] The information for instructing the terminal device to request reference signal measurement may be the first information sent by the terminal device in the aforementioned step 201 .
[0187] The content of step 221 can refer to the relevant description of the aforementioned step 201 and will not be repeated here.
[0188] Step 222: The terminal device sends information through the first cell indicating that the terminal device requests to send measurement result information.
[0189] Correspondingly, the first network device receives, through the first cell, information indicating that the terminal device requests to send measurement result information.
[0190] The information used to instruct the terminal device to request the transmission of measurement result information may be the first information transmitted by the terminal device in the aforementioned step 211. The information used to instruct the terminal device to request the transmission of measurement result information and the information used to instruct the terminal device to request the measurement of the reference signal may be the same message (in which case step 221 and step 222 may be the same step), or two different messages. The order of step 221 and step 222 may also be changed, for example, step 222 may be performed first, and then step 221. The information used to instruct the terminal device to request the transmission of measurement result information and the information used to instruct the terminal device to request the measurement of the reference signal may be carried in the same message or in two separate messages.
[0191] The content of step 222 can refer to the relevant description of the aforementioned step 211 and will not be repeated here.
[0192] In step 223 , the second network device sends at least one reference signal through the second cell.
[0193] Correspondingly, the terminal device receives at least one reference signal through the second cell.
[0194] The content of step 223 can refer to the relevant description of the aforementioned step 202 and will not be repeated here.
[0195] In step 224 , the terminal device measures at least one reference signal and obtains at least one measurement result information.
[0196] The content of step 224 can refer to the relevant description of the aforementioned step 203 and will not be repeated here.
[0197] Step 225: The terminal device sends the second information via the third cell.
[0198] Correspondingly, the third network device receives the second information through the third cell.
[0199] In this embodiment of the present application, the third cell may be the same as or different from the first cell. The third cell may be the same as or different from the second cell. In this embodiment of the present application, the second information includes at least one measurement result information. The second information may include part or all of the at least one measurement result information obtained by the terminal device in step 224. Alternatively, the second information does not include any of the at least one measurement result information obtained by the terminal device in step 224. For example, the measurement result information included in the second information may include measurement result information obtained by a reference signal measurement process triggered by a network device, or measurement result information obtained by a reference signal measurement process previously triggered by the terminal device.
[0200] The content of step 225 can refer to the relevant description of the aforementioned step 212 and will not be repeated here.
[0201] It can be seen from the solution provided in Figure 2C that the terminal device in the embodiment of the present application can trigger the measurement of the reference signal and the sending of the measurement result information through one or more information, which can speed up the subsequent beam switching process and thereby reduce the occurrence of communication interruption.
[0202] Based on the solutions provided in Figures 1, 2A, 2B and 2C, the following is a flow chart of a communication method provided by an embodiment of the present application, which is exemplified by Figure 3. Figure 3 can be regarded as an extended embodiment of Figures 2A, 2B or 2C. The relevant contents of the terminal device, the first network device, the second network device and the third network device involved in Figure 3 can be referred to the relevant introduction of Figures 2A, 2B or 2C, and will not be repeated here. The fourth network device and the fifth network device in Figure 3 can be the network device (such as a RAN node, such as a CU or DU) or a chip in a network device (such as a chip in a RAN node, such as a chip in a CU or DU) in Figure 1.
[0203] The following describes a possible implementation with reference to FIG3 . In one possible implementation, the embodiment shown in FIG3 includes steps 302, 304, and 305. In another possible implementation, the embodiment shown in FIG3 includes steps 302 and 306. Optionally, the embodiment shown in FIG3 may further include one or more of steps 301, 303, and 305.
[0204] Step 301: The fifth network device sends configuration information.
[0205] Correspondingly, the terminal device receives the configuration information.
[0206] In a possible implementation, the configuration information may be sent via a radio resource control (RRC) message.
[0207] The configuration information may include multiple items, for example, the configuration information may include one or more of the following: information for indicating scheduling resources (information A1), information for indicating resources of reference signals (information A2), information for indicating the cell that the terminal device requests to measure (information A3), indication information of the cell used to send measurement result information (information A4), indication information of resources used to send measurement result information (information A5), information for indicating the cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs (information A6), and characteristic information of the reference signal that the terminal device requests to measure (information A7).
[0208] The configuration information can also configure: scheduling resources (such as the first resource), the cell that the terminal device requests to measure (such as the second cell), the resources of the reference signal, the cell used to send the measurement result information, the resources used to send the measurement result information, and the association relationship between any multiple items in the cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs (such as information A8). For example, the configuration information can configure the association relationship between the scheduling resources (such as the first resource) and the trigger state. The trigger state can be understood as information used to indicate the resources of the reference signal (information A2), etc. Please refer to the subsequent detailed introduction. In this way, the terminal device sends the first information through the first resource, and the network device side can determine that the terminal device wants to activate (or trigger, or enable) the trigger state corresponding to the first resource based on the first resource occupied by the first information. The subsequent content will be introduced in detail, so I will not go into details here.
[0209] Information A1 is used to indicate information about scheduling resources.
[0210] For the sake of distinction, in the embodiment of the present application, the resources used to send a request for reference signal measurement and / or a request to send measurement result information are referred to as scheduling resources. The scheduling resources in this article can be replaced by resources, scheduling request resources, dedicated scheduling request resources, PUCCH or PUSCH. The scheduling resources indicated by the information for indicating the scheduling resources included in the configuration information can be understood as: resources that the terminal device can (or is allowed, or is recommended to) use when sending information for requesting reference signal measurement and / or for requesting to send measurement result information, or resources that such information can (or is allowed, or is recommended to) occupy.
[0211] The scheduling resources in the embodiments of the present application may include time domain resources and / or frequency domain resources, for example, the scheduling resources may include a period and an offset in the time domain (and / or frequency domain).
[0212] The information used to indicate the scheduling resources may include, for example, one or more of: a PUCCH identifier, a scheduling request resource identifier (the scheduling request resource identifier may be expressed in English as schedulingRequestResourceId), and a scheduling request identifier (the scheduling request identifier may be expressed in English as schedulingRequestId). The terminal device may determine the scheduling resources based on the information used to indicate the scheduling resources. For example, the terminal device may find the resources associated with the PUCCH identifier based on the PUCCH identifier, and the terminal device may send a scheduling request through the resource to request reference signal measurement and / or request to send measurement result information. The information used to indicate the scheduling resources may also include a resource identifier and / or a resource set identifier.
[0213] The resources for sending information indicating a request for reference signal measurement (scheduling resources) and the resources for sending information indicating a request for sending measurement result information (scheduling resources) may be the same or different. It can also be understood that the fourth network device may configure some resources for the terminal device, and the terminal device may use these resources to send: information indicating a request for reference signal measurement, and / or information indicating a request for sending measurement result information. The network device may determine the purpose of the information by whether the resources occupied by the information are scheduling request resources.
[0214] In one possible implementation, the information used to indicate the scheduled resources includes first resource indication information and second resource indication information. The first resource indication information is used to indicate the resource. The first resource indication information includes a resource identifier and / or a resource set identifier. The resource indicated by the first resource indication information is used to send information indicating a request for reference signal measurement. The second resource indication information is used to indicate the resource. The second resource indication information may include a resource identifier and / or a resource set identifier. The resource indicated by the second resource indication information is used to send information indicating a request for sending measurement result information. The first resource indication information and the second resource indication information are described below using information A1.1 and information A1.2, respectively.
[0215] Information A1.1, first resource indication information.
[0216] For example, if the terminal device sends information through resources and the first network device receives the information, the first network device can determine whether the resources occupied by the information belong to the resources indicated by the first resource indication information. If the first resource belongs to the resources indicated by the first resource indication information, the first network device can determine that the information is used to request reference signal measurement, or it can also be understood that: the first network device determines that the terminal device wants to trigger reference signal measurement based on the information. In another possible implementation, if the first resource does not belong to the resources indicated by the first resource indication information, the first network device can determine that the information is not for requesting reference signal measurement. In this implementation, the information sent by the terminal device may not require additional information to indicate the purpose of the information, thereby saving signaling overhead.
[0217] Information A1.2, second resource indication information.
[0218] For example, if the terminal device sends information through resources and the first network device receives the information, the first network device can determine whether the resources occupied by the information belong to the resources indicated by the second resource indication information. If the first resource belongs to the resource indicated by the second resource indication information, the first network device can determine that the information is used to request the sending of measurement result information, or it can also be understood that: the first network device determines that the terminal device wants to trigger the sending of measurement result information based on the information. In another possible implementation, if the first resource does not belong to the resource indicated by the second resource indication information, the first network device can determine that the information is not information for requesting the sending of measurement result information. In this implementation, the information sent by the terminal device may not require additional information to indicate the purpose of the information, thereby saving signaling overhead.
[0219] The first resource indication information and the second resource indication information can be two different pieces of information, or the same piece of information. For example, if the first resource indication information and the second resource indication information are the same, the resource indicated by the first resource indication information can be used to send information indicating a request for reference signal measurement, or can be used to send information indicating a request for sending measurement result information. Alternatively, the information sent via the first resource can request both reference signal measurement and measurement result information.
[0220] In the embodiments of this application, the information indicating the first resource may include, for example, a resource identifier and / or a resource set identifier of the first resource. The information indicating the first resource may include the first resource indication information and / or the second resource indication information. Alternatively, it can be understood that the first resource is used to send information requesting reference signal measurement and / or that the first resource is used to send information requesting the transmission of reference signal measurement results.
[0221] Information A2 is used to indicate the resource of the reference signal.
[0222] In the embodiment of the present application, the information for indicating the resources of the reference signal included in the configuration information may indicate the resources of the reference signal. These reference signal resources may be understood as the resources that the reference signal requested to be measured by the terminal device can (or is allowed to, or is recommended to) occupy. The terminal device may receive and measure the reference signal on the resources of the reference signal. In the embodiment of the present application, the resources of the reference signal may be replaced by the resources corresponding to the reference signal, or the resources occupied by the reference signal, etc.
[0223] In the embodiment of the present application, the reference signal resource may be indicated by some information. For example, the information used to indicate the reference signal resource may include at least one of: information used to indicate a trigger state, information used to indicate a channel state information report configuration, index information of a synchronization signal block, an identifier of the reference signal resource, an identifier of a resource set corresponding to the reference signal resource, and an identifier of a resource configuration corresponding to the reference signal resource. In this case, the configuration information may further include information indicating an association between the scheduling resource and the information used to indicate the reference signal resource.
[0224] The information used to indicate the reference signal resource may specifically include multiple types, for example, the information used to indicate the reference signal resource may include one or more of information A2.1, information A2.2, information A2.3, information A2.4, information A2.5, or information A2.6. Information A2.1 is information used to indicate the trigger state, information A2.2 is information used to indicate the channel state information report configuration, information A2.3 is index information of the synchronization signal block, information A2.4 is an identifier of the reference signal resource, information A2.5 is an identifier of the resource set corresponding to the reference signal resource, and information A2.6 is an identifier of the resource configuration corresponding to the reference signal resource.
[0225] Information A2.1 is used to indicate the trigger status.
[0226] The trigger state in the embodiment of the present application can be written as trigger state in English. The trigger state in the embodiment of the present application can also be replaced by trigger state information or trigger state configuration information, or replaced by information. In the embodiment of the present application, for the sake of convenience, it is referred to as trigger state.
[0227] In the embodiment of the present application, a trigger state may correspond to a cell, and the cell corresponding to the trigger state involved in the embodiment of the present application may be understood as the cell to which the trigger state belongs. The cell corresponding to the trigger state may include a serving cell, such as an Scell, a Pcell, or a PScell.
[0228] When the cell corresponding to the trigger state is a serving cell, the identifier of the cell corresponding to the trigger state may be carried in a serving cell identifier field in the configuration message, which may be denoted as serving cell ID in English.
[0229] In the embodiment of the present application, the information used to indicate the trigger state may include an identifier of a cell corresponding to the trigger state. The information used to indicate the trigger state may also include other information, such as an identifier of the trigger state.
[0230] For example, the information used to indicate the trigger state is the identifier of the cell (such as the serving cell) corresponding to the trigger state, such as the identifier of CC0. Then the identifier of the cell is used to indicate the trigger state corresponding to CC0. Alternatively, the identifier of the cell is used to indicate that the corresponding cell (such as the serving cell) is in the trigger state of CC0.
[0231] The trigger state in the embodiment of the present application can be associated with a resource or a resource set, and the trigger state can be associated with the resource of the reference signal. Therefore, the information used to indicate the trigger state in the embodiment of the present application can be regarded as information used to indicate the resource of the reference signal.
[0232] The following describes a form of information that may be included in a trigger state.
[0233] For example, the configuration information may configure one or more trigger states. For example, the configuration information may configure a channel state information trigger state list, which may be recorded as CSI-TriggerStateList, and the list may include multiple trigger states.
[0234] A trigger state may include one or more (for example, no more than 16) channel state information associated report configuration information (the channel state information associated report configuration information may be recorded as CSI-AssociatedReportConfigInfo).
[0235] A channel state information associated report configuration information may include a report configuration identifier (which may be recorded as reportConfigId) and channel resource information (which may be recorded as resourcesForChannel). The report configuration identifier in a channel state information associated report configuration information may be associated with the channel resource information.
[0236] Among them, the channel resource information can be associated with a resource set or a resource. For example, the channel resource information can be associated with a CSI-RS resource set, a non-zero power CSI-RS (non-zero power CSI-RS, NZP-CSI-RS) resource set, a zero power CSI-RS (zero power CSI-RS, ZP-CSI-RS) resource set, a CSI interference measurement (CSI interference measurement, CSI-IM) resource set, or a CSI synchronization signal block (CSI signal synchronization signal block, CSI-SSB) resource set. The resource set in the embodiment of the present application can be recorded as a resource set.
[0237] The resources associated with the channel resource information (or the resources in the resource set) can be understood as the resources of the reference signal. Taking the resource set associated with channel resource information as an example, the channel resource information may include the identifier of the resource set. The resource set associated with the channel resource information (which may also be referred to as the configuration information of the resource set) may also include the identifier of the resource set, so that the terminal device or network device can find the resource set associated with the channel resource information based on the channel resource information. A resource set associated with channel resource information may include relevant parameters (or information) of the resource, such as the resource set (which may also be referred to as the configuration information of the resource set) may also include the index of the resource set. The index of the resource set may include, for example, the identifier of the CSI-RS resource set, the identifier of the NZP-CSI-RS resource set, the identifier of the ZP-CSI-RS resource set, the identifier of the CSI-IM resource set, or the identifier of the CSI-SSB resource set.
[0238] A variety of information can be configured in a resource set, such as at least one of the following: one or more resources (such as SSB resources or CSI-RS resources), whether to repeat (repetition can be written as repetition in English, and repetitiong can include two states: enabled and disabled. The enabled state can be expressed in English as on, and the disabled state can be expressed in English as off. The information on whether to repeat can also be understood as whether repetiton is on or off. If repetiton is on, it can also be understood that the resources of the resource set are sent using the same downlink spatial domain filter. If repetiton is off, it can also be understood that the resources of the resource set do not need to be sent using the same downlink spatial domain filter), periodic triggering delay (aperiodicTriggeringOffset in English), the antenna ports corresponding to all NZP-CSI-RS resources in the CSI-RS resource set are the same (this meaning can also be expressed as trs-info), and spatial relationship information (which can be recorded as QCL-info).
[0239] Among them, the report configuration identifier can be understood as an example of information used to indicate the channel state information report configuration. The report configuration identifier can also be called the identifier of the channel state information report configuration. The report configuration identifier can correspond to a channel state information report configuration (the channel state information report configuration in the embodiment of the present application can be recorded as CSI-ReportConfig, and the channel state information report configuration in the implementation of the present application can be replaced with a channel state information report, or replaced with channel state information report information, or replaced with channel state information report configuration information, or replaced with information, etc.). A channel state information report configuration may include an identifier of the report configuration, so that the terminal device or network device can find out the channel state information report configuration corresponding to the report configuration identifier according to the identifier of the report configuration.
[0240] In one possible implementation, a channel state information report configuration may also include information for indicating the cell to which the reference signal resource belongs. The reference signal resource may be the resource of the reference signal indicated in the channel resource information associated with the channel state information report configuration. The information of the cell to which the reference signal resource belongs may be carried in a field of the channel state information report configuration, which may be called a carrier field in English. For example, if the channel state information report configuration indicates that the cell to which the reference signal resource belongs is CC2, then when the channel state information is activated (or triggered, or enabled), the cell to which the reference signal resource requested to be measured by the terminal device belongs is CC2, which can also be understood as the terminal device requesting to measure the reference signal of CC2.
[0241] In another possible implementation, a channel state information report configuration may also include relevant parameters (or information) of the measurement result information sent by the terminal device. For example, the channel state information report configuration may include: at least one of: report configuration type (for example, it can be recorded as reportConfigType), report quantity (for example, it can be recorded as reportQuantity), group-based beam reporting (for example, it can be recorded as groupBaseBeamReporting), or channel measurement resources (for example, it can be recorded as resourceForChannelMeasurement).
[0242] Information A2.2 is used to indicate the channel state information reporting configuration.
[0243] A channel state information report configuration (for example, it can be recorded as CSI-ReportConfig) can correspond to a cell. The cell corresponding to the channel state information report configuration involved in the embodiment of the present application can be understood as the cell to which the channel state information report configuration belongs. The cell corresponding to the channel state information report configuration may include a serving cell, such as an Scell, a Pcell, or a PScell. When the cell corresponding to the channel state information report configuration is a serving cell, the identifier of the cell corresponding to the channel state information report configuration can be carried in the serving cell identifier field in the configuration message, which can be recorded as serving cell ID in English.
[0244] In the embodiment of the present application, the information for indicating the channel state information reporting configuration may include an identifier of a cell corresponding to the channel state information reporting configuration. The information for indicating the channel state information reporting configuration may also include other information, such as an identifier of the channel state information reporting configuration.
[0245] For example, the information used to indicate the channel state information reporting configuration is the identifier of the cell (e.g., serving cell) corresponding to the channel state information reporting configuration, such as the identifier of CC0. The identifier of the cell is used to indicate the channel state information reporting configuration corresponding to CC0. Alternatively, the identifier of the cell is used to indicate that the corresponding cell (e.g., serving cell) is the channel state information reporting configuration of CC0.
[0246] The information used to indicate the channel state information report configuration can be associated with resources or resource sets, and the channel state information report configuration can be associated with the resources of the reference signal. Therefore, the information used to indicate the channel state information report configuration in the embodiment of the present application can be regarded as information used to indicate the resources of the reference signal.
[0247] For example, the channel state information report configuration is associated with the channel resource information (which may be recorded as resourcesForChannel) in the trigger state, and the resources indicated by the channel state information report configuration are the resources indicated by the channel resource information.
[0248] Regarding the channel state report configuration, channel resource information, and trigger state, please refer to the relevant description in the aforementioned information A2.1 and will not be repeated here. The channel state information report configuration in the embodiment of the present application can be configured in the trigger state or can be configured separately, that is, not configured in the trigger state.
[0249] Information A2.3, index information of synchronization signal block.
[0250] The synchronization signal block in the embodiment of the present application may include an SSB. The index information of the synchronization signal block includes information for indicating the synchronization signal block.
[0251] When the index information for the synchronization signal block is used as information for indicating the resource of the reference signal, the resource of the reference signal may be a resource associated with the synchronization signal block. For example, the resource of the reference signal is a resource associated with the SSB. The resources associated with the SSB include the CSI-RS resource set associated with the SSB and / or the resources associated with the SRS resource set. Alternatively, the resources associated with the SSB include the CSI-RS resources and / or SRS resources associated with the SSB. Optionally, the network device side (such as the fifth network device) may further configure the association relationship between the SSB and the CSI-RS resources (and / or SRS resources), and / or the network device may further configure the association relationship between the SSB and the CSI-RS resource set (and / or SRS resource set).
[0252] Information A2.4, identification of reference signal resources.
[0253] The reference signal resource identifier may include, for example, at least one of a CSI-RS resource identifier, an SRS resource identifier, and an SSB resource identifier. The reference signal resource may include the resource indicated by the reference signal resource identifier.
[0254] The identifier of the reference signal resource may be configured in the configuration information.
[0255] Information A2.5: identifier of the resource set corresponding to the reference signal resource.
[0256] In the embodiments of the present application, the resource set in English can be written as resource set. The identifier of the resource set of the reference signal resource may include, for example, at least one of the identifier of the CSI-RS resource set, the identifier of the SRS resource set, and the identifier of the SSB resource set.
[0257] Information A2.6: Identification of the resource configuration corresponding to the reference signal resource.
[0258] In the embodiments of the present application, resource configuration can be written as "resource setting" in English. Resource configuration can be associated with a resource set or a resource. When the resource configuration identifier is used as information indicating a reference signal resource, the reference signal resource can be a resource associated with the resource configuration identifier. The resource associated with the resource configuration identifier can include, for example, at least one of a CSI-RS resource set identifier, an SRS resource set identifier, an SSB resource set identifier, a CSI-RS resource identifier, an SRS resource identifier, and an SSB resource identifier.
[0259] Information A3 is used to indicate information about the cell that the terminal device requests to measure.
[0260] The information in the configuration information used to indicate the cells that the terminal device requests to measure may indicate the cells that the terminal device requests to measure. These cells may also be understood as cells that the terminal device can (or is allowed to, or is recommended to) request to measure.
[0261] The information used to indicate the cell that the terminal device requests to measure may include, for example, an identifier of the cell.
[0262] In the embodiment of the present application, the information used to indicate the cell that the terminal device requests to measure may also include other information, such as information used to indicate a trigger state. The trigger state is associated with the cell that the terminal device requests to measure. For example, the identification information of the cell carried by the carrier field mentioned in the aforementioned information A2.1 may be the identification information of the cell that the terminal device requests to measure associated with the trigger state.
[0263] In the embodiment of the present application, the information used to indicate the cell that the terminal device requests to measure may also include other information, such as information used to indicate a channel state information report configuration. The channel state information report configuration is associated with the cell that the terminal device requests to measure, such as the identification information of the cell carried by the carrier field (see the aforementioned information A2.1) in the trigger state associated with the channel state information report configuration, which may be the identification information of the cell that the terminal device associated with the trigger state requests to measure.
[0264] Information A4 is used to indicate the cell that sends the measurement result information.
[0265] The indication information of the cell for sending the measurement result information in the configuration information may indicate the cell for sending the measurement result information. These cells may also be understood as cells for which the terminal device can (or is allowed to, or is recommended to) request to send the measurement result information. These cells are used by the terminal device to send the measurement result information, but the measurement result information may include the measurement result information of the cell, or may not include the measurement result information of the cell, and may also include the measurement result information of other cells.
[0266] The indication information of the cell used to send the measurement result information may include, for example, the identifier of the cell.
[0267] Information A5: information indicating resources for sending measurement result information.
[0268] The configuration information includes indication information of resources for sending measurement result information, which can indicate the resources used to send measurement result information. These reference signal resources can be understood as resources that can (or are allowed to, or are recommended to) be occupied by the terminal device requesting to send measurement result information (or signaling carrying measurement result information).
[0269] The information indicating the resources used to transmit the measurement result information may include, for example, at least one of a resource identifier, a resource set identifier, and a resource configuration identifier. For example, the resources used to transmit the measurement result information may include PUSCH resources and / or PUCCH resources. The resources used to transmit the measurement result information may be uplink resources, which may include time domain resources and / or frequency domain resources. Another example includes configuring a reporting period and offset.
[0270] Information A6 is used to indicate that the terminal device requests to send information about the cell to which the reference signal corresponding to the measurement result information belongs.
[0271] The information in the configuration information used to indicate the cell to which the reference signal corresponding to the measurement result information requested by the terminal device belongs can indicate the cell to which the reference signal corresponding to the measurement result information requested by the terminal device belongs. These cells can also be understood as: which (one or more) cells corresponding to the measurement result information that the terminal device can (or is allowed, or is recommended) request to send. The measurement result information of these cells can be sent through other cells or this cell.
[0272] The information indicating the cell to which the terminal device requests to send the reference signal corresponding to the measurement result information may include, for example, a cell identifier. In the embodiment of the present application, the reference signal corresponding to the measurement result information may also be understood as: the measurement result information is based on the reference signal measurement of the cell.
[0273] In one possible implementation, the cell that the terminal device requests to measure (the cell indicated by information A3) is the same as or different from the cell to which the reference signal corresponding to the measurement result information requested by the terminal device belongs (the cell indicated by information A6). When the cell that the terminal device requests to measure (the cell indicated by information A3) is the same as the cell to which the reference signal corresponding to the measurement result information requested by the terminal device belongs (the cell indicated by information A6), information A3 and information A6 can be the same information or two pieces of information. In one possible implementation, when the cell that the terminal device requests to measure (the cell indicated by information A3) is the same as the cell to which the reference signal corresponding to the measurement result information requested by the terminal device belongs (the cell indicated by information A6), information A6 can be information for indicating the channel state information report configuration. Specifically, information A6 can be the identification information of the cell carried by the carrier field in the trigger state associated with the channel state information report configuration (see the aforementioned information A2.1).
[0274] Information A7 is used to indicate characteristic information of the reference signal that the terminal device requests to measure.
[0275] The information in the configuration information used to indicate the characteristics of the reference signal requested to be measured by the terminal device can indicate the characteristics of the reference signal requested to be measured by the terminal device. The characteristics of these reference signals can also be understood as: the characteristics of the reference signal that the terminal device can (or is allowed, or is recommended) to request to measure.
[0276] In the embodiment of the present application, the characteristics of the reference signal (information A7) may include one or more of the spatial relationship of the reference signal (such as the following information A7.1), whether the reference signal can be received simultaneously by the terminal device (such as the following information A7.2), whether the spatial relationship corresponding to the reference signal can be applied by the terminal device for simultaneous transmission (such as the following information A7.3), and whether it belongs to a certain number (such as one or more) of transmission receiving points (such as the following information A7.4). For example, the information used to indicate the resource of the reference signal may include information A7.2 and information A7.3, then the characteristics of the reference signal include: whether the reference signal can be received simultaneously by the terminal device (such as information A7.2), and whether the spatial relationship corresponding to the reference signal can be applied by the terminal device for simultaneous transmission (such as information A7.3). These characteristics of the reference signal can make the reference signal sent by the network device side more in line with the actual needs of the terminal device.
[0277] Information A7.1: Multiple reference signals requested by the terminal device for measurement are sent using the same downlink spatial domain filter.
[0278] In one possible implementation, information A7.1 may be understood as indicating that repetition in channel resource information (e.g., channel resource information associated with a trigger state) needs to be set to enabled (e.g., on). If the network device sends multiple reference signal symbols as required by information A7.1, the network device may repeatedly transmit the reference signal using the same beam, and the terminal device may take turns receiving using different receive beams, and then the terminal device may take turns measuring the quality of the different receive beams.
[0279] Multiple reference signals are sent using the same downlink spatial domain filter, which can be written in English as: Resources are transmitted with the same downlink spatial domain transmission filter.
[0280] Information A7.2: The multiple reference signals requested by the terminal device for measurement can be received by the terminal device simultaneously.
[0281] Information A7.2 may also be replaced by "resources of multiple reference signals requested to be measured by the terminal device can be received simultaneously by the terminal device." The corresponding English text may be: resources can be received simultaneously by the UE.
[0282] Information A7.3, the spatial filters corresponding to the multiple reference signals requested to be measured by the terminal device can be applied by the terminal device to be sent simultaneously.
[0283] For example, multiple reference signals correspond to multiple (for example, two) spatial filters, and the terminal device can simultaneously send multiple signals through the multiple spatial filters.
[0284] Information A7.4: The reference signal resources requested to be measured by the terminal device belong to the reference signal resources associated with N transmission reception points (TRPs), where N is a positive integer.
[0285] For example, N can be one, two, or other values.
[0286] Information A7.4 may also be replaced by: the reference signal resources requested to be measured by the terminal device are multiple reference signal resources respectively associated with N control resource set pool indexes (the control resource set pool index may be recorded as coresetpoolindex).
[0287] Information A7.4 may also be replaced by: the reference signal resources requested to be measured by the terminal device are multiple reference signal resources respectively associated with the serving cell and the non-serving cell (a cell whose cell identifier is different from the serving cell, such as additional PCI).
[0288] Information A7.4 may also be replaced by: the reference signal resources requested to be measured by the terminal device are reference signal resources belonging to two SRS resource sets respectively, and the two resource sets are used for codebook measurement or non-codebook measurement.
[0289] Information A7.4 may also be replaced by: the reference signal resources that the terminal device requests to measure are reference signal resources belonging to two CSI / SSB resource sets respectively.
[0290] Information A8 is used to indicate information that is associated with any of the following: scheduling resources (such as the first resource), the cell that the terminal device requests to measure (such as the second cell), the resource of the reference signal, the cell used to send the measurement result information, the resource used to send the measurement result information, and the cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs.
[0291] Information A8 can be understood as information used to indicate the association relationship between any two or more items of information A1, information A2, information A3, information A4, information A5, information A6, and information A7. In this way, the terminal device can indicate some of the multiple items of information that have an association relationship, thereby saving signaling overhead. Several examples are provided below. For other examples of association relationships between any two or more items, please refer to the following examples and will not be repeated here.
[0292] In example 1, the configuration information includes information indicating the association between the scheduling resource and the information indicating the reference signal resource (such as the identifier of the reference signal resource, or the trigger status). These associations can be represented in a table or other form.
[0293] For example, at least one scheduling resource indicated by the configuration information includes a first resource, and the configuration information may also include information indicating the association relationship between the first resource and information for indicating a resource for a reference signal (such as an identifier of a resource for a reference signal, and another example, a trigger state). The terminal device sends the first information through the first resource. The first network device receives the first information, and the first network device can search the configuration information for information for indicating a resource for a reference signal associated with the first resource (such as an identifier of a resource for a reference signal, and another example, a trigger state). The information for indicating a resource for a reference signal is the information for indicating a resource for a reference signal that the terminal device requests to activate (or trigger, or enable) as determined by the first network device (such as an identifier of a resource for a reference signal, and another example, a trigger state). It can also be understood that the resource for a reference signal indicated by the information for indicating a resource for a reference signal is the resource for a reference signal that the terminal device requests to measure as determined by the first network device. It can be seen that in this solution, the terminal device does not need to carry information for indicating a resource for a reference signal in the first information, thereby reducing signaling overhead.
[0294] In the embodiment of the present application, the network device subsequently used to receive the first information is the first network device. The first network device and the fifth network device can be the same network device, or two devices of the same physical device. The first network device can obtain the configuration information, for example, by exchanging signals with the fifth network device, or the first network device can obtain the configuration information without exchanging signals with the fifth network device.
[0295] Example 2: The configuration information further indicates that the scheduling resources are associated with the information used to indicate the resources of the reference signal.
[0296] Taking the example of information indicating a reference signal resource including a trigger state, the configuration information may include information indicating an association between the scheduled resource and the trigger state. The association between the scheduled resource and the trigger state may be indicated explicitly or implicitly. For related solutions, refer to the aforementioned solution where the configuration information indicates an association between the scheduled resource and the reference signal resource. Similar to this solution, no further details will be given.
[0297] For example, at least one scheduling resource indicated by the configuration information includes a first resource, and the configuration information may further include information for indicating a trigger state. In another possible implementation, the configuration information may further include information for indicating an association between the first resource and the trigger state. The terminal device sends the first information through the first resource. The first network device receives the first information, and the first network device can search the trigger state associated with the first resource from the configuration information, and then the first network device can determine the trigger state that the terminal device requests to enable (or activate, or trigger). It can be seen that in this solution, the terminal device does not need to carry information for indicating the trigger state in the first information, thereby reducing signaling overhead.
[0298] In the above example, the correlation between scheduling resources and other information is used as an example to introduce the relationship. In actual applications, there may also be a correlation between any two or more items. For example, there is a correlation between the information for indicating the resources of the reference signal (information A2) and the characteristics of the reference signal for indicating the terminal device to request measurement (information A1). When the terminal device sends the information for indicating the resources of the reference signal, the network device can determine the characteristics of the reference signal requested by the terminal device based on the information. In this solution, the terminal device does not need to send the characteristics of the reference signal for indicating the terminal device to request measurement, thereby saving signaling overhead. For relevant examples of the correlation between any two items of information A1, information A2, information A3, information A4, information A5, information A6 and information A7, please refer to the above examples, as well as the relevant descriptions in the aforementioned information A1, information A2, information A3, information A4, information A5, information A6 and information A7, which will not be repeated here.
[0299] The association relationship between any multiple items of information A1, information A2, information A3, information A4, information A5, information A6 and information A7 may be indicated in an explicit manner or in an implicit manner.
[0300] For example, there is an association relationship between the scheduling resource and the information used to indicate the reference signal resource (such as the identifier of the reference signal resource, or the triggering status).
[0301] In one possible implementation, the configuration information includes at least one piece of information for indicating a scheduling resource and at least one piece of information for indicating a reference signal resource. There is a correspondence between the one scheduling resource and one or more pieces of information for indicating a reference signal resource (such as an identifier of a reference signal resource, and another example, a trigger state), and the correspondence can be specified by a protocol or pre-configured or set to the terminal device. For example, the terminal device determines the information for indicating a reference signal resource corresponding to the scheduling resource by ranking the information for indicating the scheduling resource in at least one piece of information for indicating the scheduling resource in the configuration information (such as ranking first), such as the reference signal resource being the information ranked first in at least one piece of information for indicating a reference signal resource in the configuration information (such as an identifier of a reference signal resource, and another example, a trigger state).
[0302] In another possible implementation, the configuration information includes information indicating an association between scheduling resources and information indicating reference signal resources (such as an identifier of a reference signal resource, or a trigger status).
[0303] For another example, there is an association between the scheduling resources and the information indicating the cell that the terminal device requests to measure.
[0304] In one possible implementation, the configuration information includes information indicating at least one scheduling resource and information indicating at least one cell. The at least one cell is the cell requested to be measured by the terminal device. A corresponding relationship exists between the at least one scheduling resource and the at least one cell. This corresponding relationship can be specified by a protocol or pre-configured or set for the terminal device, such as one scheduling resource corresponding to one or two cells. The terminal device can determine the cell corresponding to a scheduling resource by using the order of the scheduling resources indicated by the information indicating the at least one scheduling resource and the order of the cells indicated by the information indicating the cells.
[0305] In another possible implementation, the configuration information includes information that associates scheduled resources with cells. The cell is the cell for which the terminal device requests measurement. These associations can be represented in a table or other form. Subsequently, the terminal device can send information using the scheduled resources, so that the first network device determines the cell for which the terminal device requests measurement based on the scheduled resources and these associations, thereby reducing signaling overhead.
[0306] In another possible implementation, the configuration information includes at least one channel state information report configuration, wherein the at least one channel state information report configuration includes a channel state report configuration, recorded as channel state information report configuration #1, and channel state information report configuration #1 corresponds to a cell (recorded as cell #1). It can be understood that channel state information report configuration #1 belongs to or comes from cell #1, and can be specifically recorded as: channel state information report configuration #1 of cell #1.
[0307] The channel state information reporting configuration #1 of cell #1 is associated with at least one of the following:
[0308] Reference signal resources of cell #2 (e.g., an identifier of the reference signal resources associated with cell #2, or an identifier of a resource set corresponding to the reference signal resources associated with cell #2, or an identifier of a resource configuration corresponding to the reference signal resources associated with cell #2);
[0309] First resource;
[0310] Information of the cell to which the first resource belongs (e.g., the first cell); or
[0311] Second resource.
[0312] For example, the terminal device sends first information through the first resource of the first cell, where the first information indicates a request to send the measurement result, and then the terminal device sends the measurement result of the reference signal resource of cell #2 through the second resource.
[0313] The related examples of other association relationships in information A1, information A2, information A3, information A4, information A5, information A6 and information A7 are similar and will not be repeated here.
[0314] Step 302: The terminal device sends first information through the first cell.
[0315] Correspondingly, the first network device receives the first information through the first cell.
[0316] The first information is used to instruct the terminal device to request measurement of a reference signal. Alternatively, the first information is used to request transmission of measurement result information. Alternatively, the first information is used to request measurement of a reference signal and transmission of measurement result information.
[0317] In one possible implementation, the first information may include one or more of the following information B1, information B2, information B3, information B4, information B5, information B6, information B7, and information B8. For example, when the first information is at least used to indicate that the terminal device requests to measure a reference signal, the first information may include at least one of information for indicating a resource of the reference signal (information B1), information for indicating a cell (such as a second cell) that the terminal device requests to measure (information B2), information for indicating a characteristic of the reference signal that the terminal device requests to measure (information B3), and information for indicating that the terminal device requests to measure the reference signal (information B7). For another example, when the first information at least indicates that the terminal device requests to send measurement result information, the first information may include at least one of information for indicating a cell for sending the measurement result information (information B4), information for indicating a resource for sending the measurement result information (information B5), information for indicating a cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs (information B6), and information for indicating that the terminal device requests to send the measurement result information (information B8).
[0318] The following introduces these information separately.
[0319] Information B1 is used to indicate information about the resource of the reference signal.
[0320] The information used to indicate the reference signal resource in the first information may indicate the reference signal resource, which may be understood as the resource corresponding to the reference signal requested by the terminal device to measure through the first information. The resource may belong to the reference signal resource indicated by the configuration information. Alternatively, the resource may not belong to the reference signal resource indicated by the configuration information, for example, the configuration information does not indicate the reference signal resource, or step 301 is not performed.
[0321] The information used to indicate the resources of the reference signal may include one or more of information used to indicate the trigger status (see information A2.1), information used to indicate the channel state information report configuration (see information A2.2), index information of the synchronization signal block (see information A2.3), an identifier of the reference signal resource (see information A2.4), an identifier of the resource set corresponding to the reference signal resource (see information A2.5), or an identifier of the resource configuration corresponding to the reference signal resource (see information A2.6).
[0322] When the first information includes information for indicating a trigger state (see information A2.1), the first information also indicates that the resources of the reference signal requested to be measured by the terminal device include: resources associated with the trigger state (such as resources associated with the channel resource information associated with the trigger state).
[0323] When the first information includes information for indicating the channel state information report configuration (see information A2.2), the first information also indicates that the resources of the reference signal requested by the terminal device for measurement include: resources associated with the channel state information report configuration (such as resources associated with the channel resource information associated with the trigger state associated with the channel state information report configuration).
[0324] When the first information includes the index information of the synchronization signal block (see information A2.3), the first information also indicates that the resources of the reference signal requested to be measured by the terminal device include: the resources associated with the synchronization signal block (such as the CSI-RS resource set associated with the SSB, etc.).
[0325] When the first information includes the identifier of the reference signal resource (see information A2.4), the first information also indicates that the reference signal resources requested to be measured by the terminal device include: resources associated with the identifier of the reference signal resource (such as resources associated with the channel resource information associated with the trigger state).
[0326] When the first information includes the identifier of the resource set corresponding to the reference signal resource (see information A2.5), the first information also indicates that the resources of the reference signal requested to be measured by the terminal device include: resources associated with the identifier of the resource set corresponding to the reference signal resource (such as resources associated with the channel resource information associated with the trigger state).
[0327] When the first information includes the identifier of the resource configuration corresponding to the reference signal resource (see information A2.6), the first information also indicates that the resources of the reference signal requested to be measured by the terminal device include: the resources associated with the identifier of the resource configuration (such as the resources associated with the channel resource information associated with the trigger state).
[0328] The relevant content of information B1 is similar to the relevant content in the aforementioned information A2, so you can refer to it and will not repeat it here.
[0329] Information B2 is used to indicate information about the cell (such as the second cell) that the terminal device requests to measure.
[0330] The information in the first information used to indicate the cell requested by the terminal device for measurement may indicate the cell requested by the terminal device for measurement, which may be understood as the cell requested by the terminal device for measurement through the first information. The cell may belong to the cell indicated by the configuration information as being allowed (or recommended) for the terminal device to request measurement. Alternatively, the cell may not belong to the cell indicated by the configuration information as being allowed (or recommended) for the terminal device to request measurement, for example, the configuration information does not indicate the cell requested by the terminal device for measurement, or step 301 is not performed.
[0331] For information B2, please refer to the relevant description of the aforementioned information A3 and will not be repeated here.
[0332] Information B3 is used to indicate the cell that sends the measurement result information.
[0333] The indication information of the cell for sending the measurement result information in the first information may indicate the cell for sending the measurement result information. The cell may be understood as the cell for which the terminal device requests to send the measurement result information through the first information. The cell may belong to the cell indicated by the configuration information as allowing (or suggesting) the terminal device to request measurement. Alternatively, the cell may not belong to the cell indicated by the configuration information as allowing (or suggesting) the terminal device to request measurement, for example, the configuration information does not indicate the cell for which the terminal device requests measurement, or step 301 is not performed.
[0334] For information B3, please refer to the relevant description of the aforementioned information A4, which will not be repeated here.
[0335] Information B4: information indicating resources for sending measurement result information.
[0336] The indication information of the resources used to send the measurement result information in the first information may indicate the resources occupied by sending the measurement result information. The resources may be understood as the resources occupied by the signaling requested by the terminal device through the first information for sending the measurement result information. The resources may belong to the resources indicated by the configuration information for sending the measurement result information. Alternatively, the resources may not belong to the resources indicated by the configuration information for sending the measurement result information, for example, the configuration information does not indicate the resources used to send the measurement result information, or step 301 is not performed.
[0337] For information B4, please refer to the relevant description of the aforementioned information A5 and will not be repeated here.
[0338] Information B5 is used to indicate information of the cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs.
[0339] The information in the first information used to indicate the cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs can indicate the cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs. The cell can be understood as the cell corresponding to the measurement result information requested to be sent by the terminal device through the first information (the measurement result information is obtained by measuring based on the reference signal of the cell). The cell may belong to the cell to which the reference signal corresponding to the measurement result information allowed (or recommended) to be sent by the terminal device as indicated by the configuration information belongs. Alternatively, the cell may not belong to the cell to which the reference signal corresponding to the measurement result information allowed (or recommended) to be sent by the terminal device as indicated by the configuration information belongs, for example, the configuration information does not indicate the cell to which the reference signal corresponding to the measurement result information sent by the terminal device belongs, or step 301 is not executed.
[0340] For information B5, please refer to the relevant description of the aforementioned information A6, which will not be repeated here.
[0341] Information B6 is information indicating characteristics of the reference signal that the terminal device requests to measure.
[0342] The information in the first information for indicating the characteristics of the reference signal requested to be measured by the terminal device may indicate the characteristics of the reference signal requested to be measured by the terminal device, and the characteristics may be understood as the characteristics of the reference signal requested to be measured by the terminal device through the first information. The characteristics may belong to the characteristics of the reference signal indicated by the configuration information as being allowed (or recommended) for the terminal device to measure. Alternatively, the cell may not belong to the characteristics of the reference signal indicated by the configuration information as being allowed (or recommended) for the terminal device to measure, such as the configuration information does not indicate the characteristics of the reference signal measured by the terminal device, or step 301 is not performed.
[0343] In the embodiment of the present application, the characteristics of the reference signal may include one or more of the following: the spatial relationship of the reference signal (see information A7.1), whether the reference signal can be received simultaneously by the terminal device (see information A7.2), whether the spatial relationship corresponding to the reference signal can be applied by the terminal device for simultaneous transmission (see information A7.3), and whether it belongs to a certain number (such as one or more) of transmission receiving points (see information A7.4). For example, the information used to indicate the characteristics of the reference signal may include whether the reference signal can be received simultaneously by the terminal device (see information A7.2) and whether the spatial relationship corresponding to the reference signal can be applied by the terminal device for simultaneous transmission (see information A7.3). The characteristics of these reference signals can make the reference signal sent by the network device side more compatible with the actual needs of the terminal device.
[0344] In one possible implementation, each of information B6.1, information B6.2, information B6.3 and information B6.4 can be set with a characteristic identifier (the characteristic identifier can be replaced by an identifier, index information or number) to indicate that the characteristic of the reference signal requested to be measured by the terminal device can be one or more of these characteristic identifiers. The first network device can pre-configure the association relationship between the characteristic identifier and each information, and then determine the characteristic of the reference signal corresponding to the characteristic identifier based on the characteristic identifier carried in the first information.
[0345] In another possible implementation, the characteristics of the reference signal used to indicate the terminal device's request for measurement may be embodied in the form of a bitmap. For example, a characteristic of a reference signal may correspond to a field in the first information, and a bit in the field may correspond to one of the information. If a bit in the field is 1, it indicates that the reference signal requested by the terminal device to measure satisfies the characteristic corresponding to the bit; if a bit in the field is 0, it indicates that the reference signal requested by the terminal device to measure does not need to meet the characteristic corresponding to the bit.
[0346] For the relevant content of information B6, please refer to the relevant content of the aforementioned information A7 and will not be repeated here.
[0347] Information B7 is used to indicate that the terminal device requests to measure a reference signal.
[0348] The first information includes information for instructing the terminal device to request reference signal measurement. The first network device may determine, based on the information, that the first information is used to trigger the terminal device to request reference signal measurement.
[0349] Information B8 is used to indicate that the terminal device requests to send measurement result information.
[0350] The first information includes indication information of resources used to send the measurement result information. The first network device may determine, based on the information, that the first information is used to trigger the sending of the measurement result information.
[0351] Information B7 and information B8 may be the same information or two pieces of information. If they are the same information, when the first information includes the information, the first network device may determine based on the information that the first information is used to trigger reference signal measurement and trigger the sending of measurement result information.
[0352] In another possible implementation, the terminal device may determine the first resource, and the first resource belongs to the scheduling resource. The first resource may be associated with one or more of information B1, information B2, information B3, information B4, information B5, information B6, information B7, and information B8. In this way, when the terminal device sends the first information through the first resource, the first network device may determine the information associated with the first resource based on the first resource occupied by the first information. For example, the first resource may be associated with one or more of information B1, information B2, information B3, information B4, information B5, information B6, information B7, and information B8. It can be understood that the network device may configure the PUCCH identifier of the first resource, the scheduling request resource identifier (the scheduling request resource identifier in English can be expressed as schedulingRequestResourceId, for example), and the scheduling request identifier (the scheduling request identifier in English can be expressed as schedulingRequestId, for example) to be associated with one or more of information B1, information B2, information B3, information B4, information B5, information B6, information B7, and information B8.
[0353] For example, if the first resource is associated with information (information B7) for indicating that the terminal device requests measurement of a reference signal, it can also be understood that the first resource belongs to the resource indicated by the first resource indication information. When the terminal device sends the first information through the first resource, the first network device determines that the first resource is associated with the information (information B7) for indicating that the terminal device requests measurement of a reference signal (it can also be understood that the first network device determines that the first resource belongs to the resource indicated by the first resource indication information), then the first network device determines that the first information indicates that the terminal device requests measurement of a reference signal.
[0354] To give another example, the first resource is associated with information about resources for indicating a reference signal (such as a trigger state (information B1)). The terminal device sends the first information through the first resource. The first network device receives the first information, and the first network device can search for information about resources for indicating a reference signal associated with the first resource from the configuration information (such as searching for a trigger state associated with the first resource). The information about resources for indicating a reference signal (such as a trigger state) is the information about resources for indicating a reference signal (such as a trigger state) that the terminal device requests to activate (or trigger, or enable) determined by the first network device. It can be seen that in this solution, the terminal device does not need to carry information about resources for indicating a reference signal in the first information, thereby reducing signaling overhead.
[0355] To give another example, the first resource is associated with a cell that the terminal device requests to measure, for example, the cell that the terminal device associated with the first resource requests to measure is the second cell. The association relationship can be configured through the aforementioned configuration information, and the configuration information can also include information for indicating the second cell. In another possible implementation, the configuration information can also include information for indicating the association relationship between the first resource and the second cell. The terminal device sends the first information through the first resource. The first network device receives the first information, and the first network device can search the configuration information for the cell that the terminal device associated with the first resource requests to measure, and find out that the cell that the terminal device associated with the first resource requests to measure is the second cell. The first network device can determine that the first information indicates that the terminal device requests to measure the second cell. It can be seen that in this solution, the terminal device does not need to carry information for indicating the cell that the terminal device requests to measure in the first information, thereby reducing signaling overhead.
[0356] For examples of the association relationship between the first resource and any one or more of information B1, information B2, information B3, information B4, information B5, information B6, information B7 and information B8, please refer to the above examples and the relevant content in step 301, which will not be repeated here.
[0357] In another possible implementation, there may be an association relationship between any multiple of information B1, information B2, information B3, information B4, information B5, information B6, information B7, and information B8, and the terminal device may indicate information #1 (any one or more of information B1, information B2, information B3, information B4, information B5, information B6, information B7, and information B8) to the network device, and the network device may also determine other information associated with the information #1 based on information #1. The above example is introduced using information #1 as the first resource. In actual applications, information #1 may also be other content. For example, information #1 may be information for indicating a resource of a reference signal, and the information associated with information #1 may be any one or more of information B2, information B3, information B4, information B5, information B6, information B7, and information B8. For related examples, please refer to the above description and will not be repeated here.
[0358] Step 303: The fourth network device sends third information via the fourth cell.
[0359] Correspondingly, the terminal device receives the third information through the fourth cell.
[0360] In one possible implementation, the fourth network device sends the third information only after the first network device receives the first information. In this embodiment of the present application, the fourth network device and the first network device can be the same network device, or two devices of the same physical device. The fourth network device can obtain the first information, for example, by exchanging signals with the first network device, or the fourth network device can obtain the first information without exchanging signals with the first network device.
[0361] In the embodiments of the present application, the third information sent by the fourth network device can be understood as a response to the first information, or can also be understood as information configured for the terminal device by the network device based on the reference signal measurement and / or measurement result information reported by the terminal device. The third information sent by the fourth network device via the fourth cell can trigger certain parameters, such as a trigger state, etc. These parameters can be the same as or different from the parameters requested in the first information.
[0362] There are multiple implementation forms of the content indicated by the third information, which are exemplified below by implementation mode C1 and implementation mode C2. In implementation mode C1, the third information is used to indicate the successful reception or unsuccessful reception of the first information. In implementation mode C2, the third information is used to: trigger the terminal device to measure the reference signal of the second cell, and / or trigger the terminal device to send measurement result information. Implementation mode C1 and implementation mode C2 can be executed separately or in combination, for example, the third information is used to indicate the successful reception of the first information, and is used to trigger the terminal device to measure the reference signal of the second cell and / or trigger the terminal device to send measurement result information.
[0363] In implementation mode C1, the third information is used to indicate whether the first information is successfully received or not.
[0364] In implementation C1, in one possible implementation, the third information may carry an acknowledgment (ACK) or a negative acknowledgment (NACK). When the third information carries an ACK, the third information may indicate that the first information was successfully received. When the third information carries a NACK, the third information may indicate that the first information was not successfully received.
[0365] In another possible implementation, the third information may further indicate whether the terminal device is allowed to use the information indicated by the first information. For example, if the first information indicates a cell that the terminal device requests to be measured, and the third information carries an ACK (or the third information is used to indicate successful reception of the first information), then the third information indicates that the terminal device is allowed to use the cell that the terminal device requested to be measured indicated by the first information; if the third information carries a NACK (or the third information is used to indicate unsuccessful reception of the first information), then the third information indicates that the terminal device is not allowed to use the cell that the terminal device requested to be measured indicated by the first information.
[0366] In implementation C2, the third information is used to: trigger the terminal device to measure the reference signal of the second cell, and / or trigger the terminal device to send measurement result information.
[0367] The content of implementation mode C2 may correspond to the first information. For example, when the first information is used to request measurement of the reference signal of the second cell: the third information may trigger the terminal device to measure the reference signal of the second cell; or, the third information may trigger the terminal device to measure the reference signal of the second cell, and trigger the terminal device to send measurement result information. For another example, when the first information is used to request the sending of measurement result information: the third information may trigger the terminal device to send measurement result information; or, the third information may trigger the terminal device to measure the reference signal of the second cell, and trigger the terminal device to send measurement result information.
[0368] The third information may include multiple pieces of information. For example, the third information may include one or more of the following information C2.1, information C2.2, information C2.3, information C2.4, information C2.5, information C2.6, information C2.7, and information C2.8. For example, when the third information is at least used to trigger the terminal device to measure a reference signal, the third information may include at least one of information for indicating a resource of the reference signal (information C2.1), information for indicating a cell (such as a second cell) to be measured by the terminal device (information C2.2), characteristics of the reference signal to be measured by the terminal device (information C2.3), and information for instructing the terminal device to measure the reference signal (information C2.7). For another example, when the third information is at least used to trigger the terminal device to send measurement result information, the third information may include at least one of information for indicating the cell to which the terminal device sends the measurement result information (information C2.4), information for indicating the resources for the terminal device to send the measurement result information (information C2.5), information for indicating the cell to which the reference signal corresponding to the measurement result information sent by the terminal device belongs (information C2.6), and information for indicating the terminal device to send the measurement result information (information C2.8).
[0369] Information C2.1 is used to indicate the resource of the reference signal.
[0370] The information used to indicate the resources of the reference signal included in the third information may indicate the resources of the reference signal, which may be understood as the resources occupied by the reference signal that the fourth network device recommends (or instructs, or allows) the terminal device to measure.
[0371] The information used to indicate the resources of the reference signal may include one or more of information used to indicate the trigger status (see information A2.1), information used to indicate the channel state information report configuration (see information A2.2), index information of the synchronization signal block (see information A2.3), an identifier of the reference signal resource (see information A2.4), an identifier of the resource set corresponding to the reference signal resource (see information A2.5), or an identifier of the resource configuration corresponding to the reference signal resource (see information A2.6).
[0372] The cell corresponding to the trigger state indicated by the information for indicating the trigger state may be the same as or different from the fourth cell. The third information may be a media access control control element (MAC CE) or a DCI. For example, the third information is a DCI, and the DCI carries the identifier of CC#2, and the DCI is used to trigger the trigger state corresponding to CC#2. It can also be understood that CC#2 is the cell corresponding to the trigger state (such as a serving cell). The DCI is sent by the fourth network device through CC#1, and CC#1 and CC#2 may be two different (or the same) cells. It can be seen from this example that the fourth network device can trigger (or activate) the trigger state of another cell through the DCI sent by one cell, thereby improving the flexibility of the solution, and the cell used to transmit the DCI may be a cell with better communication quality or unaffected, thereby improving the success rate of receiving the DCI.
[0373] In another possible implementation, the terminal device may also receive a piece of information for indicating a trigger state. For example, the third information is, for example, DCI, and the terminal device may also receive a MAC CE before receiving the DCI, such as the fourth network device sending the MAC CE to the terminal device. The MAC CE may indicate the cell to which the triggered (or activated) trigger state belongs. For example, the MAC CE includes a cell identifier field, and the cell identifier carried by the field is the cell corresponding to the trigger state indicated in the DCI (such as the CSI request field of the DCI). Similarly, the cell to which the triggered (or activated) trigger state indicated by the MAC CE belongs (such as CC#2) may be different from or the same as the cell that sends the MAC CE (or the cell that sends the DCI) (such as CC#1).
[0374] In one possible implementation, when the fourth cell is different from the cell corresponding to the trigger status and / or channel status information reporting configuration, the priority of the terminal device in sending the measurement result information is lower than: the measurement result information sending process associated with the trigger status information and / or channel status information reporting configuration corresponding to the fourth cell.
[0375] For example, if CC#1 is different from CC#2, the priority of sending the measurement result information associated with the triggering state of CC#2 (or the channel state information reporting configuration of CC#2) triggered by DCI through CC#1 is lower than the priority of sending the measurement result information associated with the triggering state of CC#1 (or the channel state information reporting configuration of CC#1) triggered (or activated, or enabled) by DCI through CC#1.
[0376] It can also be understood that the transmission of measurement result information associated with the triggering status and / or channel state information of other cells triggered (or activated, or enabled) by the fourth network device via the fourth cell has a lower priority than the measurement result information associated with the triggering status and / or channel state information of the fourth cell. "The fourth network device triggers (or activates, or enables) the transmission of measurement result information associated with the triggering status and / or channel state information of other cells via the fourth cell" can also be replaced by: "The fourth network device triggers (or activates, or enables) the transmission of measurement result information associated with the triggering status and / or channel state information across cells," or "The fourth network device schedules the reporting of measurement result information across cells." "The fourth network device triggers (or activates, or enables) the transmission of measurement result information associated with the triggering status and / or channel state information of the fourth cell via the fourth cell" can also be replaced by: "The fourth network device triggers (or activates, or enables) the transmission of measurement result information associated with the triggering status and / or channel state information of the fourth cell in the same cell," or "The fourth network device schedules the reporting of measurement result information in the same cell." In this way, the transmission of measurement result information associated with cross-cell scheduling will not cause significant interference to the transmission of measurement result information associated with intra-cell scheduling.
[0377] For example, when the reporting of the cross-cell scheduling measurement result information of the fourth network device overlaps with the reporting of the same-cell scheduling measurement result information of the fourth network device in at least one OFDM symbol in the time domain of the same subcarrier, then the priority of reporting the cross-cell scheduling measurement result information is lower than the reporting of the same-cell scheduling measurement result information, and the terminal device can multiplex the reporting or discard the cross-cell scheduling measurement result information (i.e., not report) according to the priority rule. In one possible implementation, the reporting of the measurement result information has the following priority rules: iCSI (z,y,k,c,s)=3·N cells ·M s ·z+2·Ncells ·M s y+N cells ·M s k+M s c+s
[0378] Wherein, z=0 indicates that the network device (such as the fourth network device) schedules reporting of measurement result information across cells; z=1 indicates that the network device (such as the fourth network device) schedules reporting of measurement result information within the same cell;
[0379] y=0 indicates aperiodic CSI reporting carried by PUSCH, y=1 indicates semi-persistent CSI reporting carried by PUSCH, y=2 indicates semi-persistent CSI reporting carried by PUCCH, and y=3 indicates periodic CSI reporting carried by PUCCH;
[0380] k=0 indicates that the CSI report of L1-RSRP or L1-SINR is carried, and k=1 indicates that the CSI report of L1-RSRP or L1-SINR is not carried;
[0381] c represents the serving cell index;
[0382] N cells Indicates the maximum number of serving cells configured by a higher-level parameter (the higher-level parameter may be maxNrofServingCells);
[0383] s is the report configuration identifier (the report configuration identifier can be recorded as reportConfigID);
[0384] M s Indicates the maximum number of CSI report configurations configured by a higher-level parameter (the higher-level parameter may be maxNrofCSI-ReportConfigurations);
[0385] Pri iCSI (z,y,k,c,s) represents the priority, where Pri iCSI The smaller the (z,y,k,c,s) value is, the higher the priority can be.
[0386] In an embodiment of the present application, the fourth network device sends the third information through the fourth cell, which can be used to schedule the trigger state and / or channel state information reporting configuration of the fourth cell or the non-fourth cell. Since the third information is sent by the fourth network device based on the first information, the process also belongs to the measurement result information reporting process triggered by the terminal device. In another possible implementation method, the scheme provided in the embodiment of the present application can also be applied to the measurement result information reporting process triggered by the network device. In this scheme, there is no need for the terminal device to first trigger or activate the reporting of the measurement result information. Instead, the network device side first triggers or activates the reporting of the measurement result information. In this scheme, the network device sends the cell used to trigger the measurement result information reporting, and the cell associated with the trigger state and / or channel state information reporting configuration actually activated by the network device through the information can be different (or the same). For example, the network device can send the measurement result information associated with the trigger state of CC#2 (or the channel state information reporting configuration of CC#2) triggered by the DCI sent on CC#1. The DCI is not based on the information sent by the first information of the terminal device, but is sent autonomously by the network device.
[0387] In one possible implementation, when the fourth cell is different from the cell corresponding to the trigger state (or channel state information reporting configuration), the information used to indicate the trigger state (or channel state information reporting configuration) may include an identifier of the cell corresponding to the trigger state (or channel state information reporting configuration), thereby enabling the terminal device to determine that the third information is not what triggers (or activates) the trigger state (or channel state information reporting configuration) corresponding to the fourth cell.
[0388] In another possible implementation, when the fourth cell is different from the cell corresponding to the trigger state (or channel state information reporting configuration), the information used to indicate the trigger state (or channel state information reporting configuration) may not include the identifier of the cell corresponding to the trigger state (or channel state information reporting configuration), and the terminal device can determine that the third information triggers (or activates) the trigger state (or channel state information reporting configuration) corresponding to the fourth cell.
[0389] The relevant content of information C2.1 is similar to the relevant content in the aforementioned information A2 and information B1, so please refer to them and do not repeat them here.
[0390] Information C2.2 is used to indicate information about the cell measured by the terminal device.
[0391] The information included in the third information for indicating the cell measured by the terminal device may indicate the cell measured by the terminal device, which may be understood as the cell that the fourth network device recommends (or instructs, or allows) the terminal device to measure. The cells measured by the terminal device indicated by the third information and the first information may be the same or different. The terminal device may use or not use the cell measured by the terminal device indicated by the third information. The cell measured by the terminal device indicated by the third information may belong to the cell measured by the terminal device indicated by the configuration information.
[0392] For information C2.2, please refer to the relevant descriptions of information A3 and information B2 mentioned above and will not be repeated here.
[0393] Information C2.3 is used to indicate the cell to which the terminal device sends the measurement result information.
[0394] The information included in the third information for indicating the cell in which the terminal device sends the measurement result information can indicate the cell in which the terminal device sends the measurement result information. The cell can be understood as the cell in which the fourth network device recommends (or instructs, or allows) the terminal device to send the measurement result information (it can be understood as: the cell is used to transmit signaling including the measurement result information).
[0395] For information C2.3, please refer to the relevant descriptions of information A4 and information B3 mentioned above and will not be repeated here.
[0396] Information C2.4 is used to indicate the resource for the terminal device to send measurement result information.
[0397] The information included in the third information for indicating the resources for the terminal device to send measurement result information can indicate the resources for the terminal device to send measurement result information. The resources can be understood as the resources that the fourth network device recommends (or instructs, or allows) the terminal device to send measurement result information (it can be understood as: the resources are used to transmit signaling including measurement result information).
[0398] For information C2.4, please refer to the relevant descriptions of information A5 and information B4 mentioned above and will not be repeated here.
[0399] Information C2.5 is used to indicate information of the cell to which the reference signal corresponding to the measurement result information sent by the terminal device belongs.
[0400] The information included in the third information for indicating the cell to which the reference signal corresponding to the measurement result information sent by the terminal device belongs can indicate the cell to which the reference signal corresponding to the measurement result information sent by the terminal device belongs. The cell can be understood as the cell to which the fourth network device recommends (or instructs, or allows) the terminal device to send the reference signal corresponding to the measurement result information to which the terminal device belongs (the measurement result information obtained by the terminal device measuring the reference signal of the cell).
[0401] For information C2.5, please refer to the relevant descriptions of information A6 and information B5 mentioned above, and will not be repeated here.
[0402] Information C2.6 is used to indicate the characteristics of the reference signal measured by the terminal device.
[0403] The information included in the third information for indicating the characteristics of the reference signal measured by the terminal device may indicate the characteristics of the reference signal measured by the terminal device, which may be understood as the characteristics of the reference signal that the fourth network device recommends (or indicates, or allows) the terminal device to measure.
[0404] For information C2.5, please refer to the relevant descriptions of information A7 and information B6 mentioned above, and will not be repeated here.
[0405] Information C2.7 is used to instruct the terminal device to measure the reference signal.
[0406] The third information includes information for instructing the terminal device to measure a reference signal. The terminal device may determine, based on the information, that the third information is at least used to trigger reference signal measurement of the terminal device.
[0407] Information C2.8 is used to instruct the terminal device to send measurement result information.
[0408] The third information includes information for instructing the terminal device to send the measurement result information. The terminal device may determine, based on the information, that the third information is at least used to trigger the sending of the measurement result information.
[0409] Information C2.7 and information C2.8 may be the same information or two pieces of information. If they are the same information, then when the third information includes this information, it can be determined based on this information that the third information is used to trigger reference signal measurement and trigger the sending of measurement result information.
[0410] In an embodiment of the present application, the first information sent by the terminal device may indicate some information, such as one or more of the above-mentioned information B1, information B2, information B3, information B4, information B5, information B6, information B7, and information B8. The fourth network device may respond to the request of the terminal device, such as approving the terminal device to use the information requested by the terminal device. Alternatively, the fourth network device may not approve the terminal device to use the information requested by the terminal device.
[0411] The fourth network device can also reconfigure some information for the terminal device through the third information. The type of information configured by the third information (also referred to as a parameter item) may include part or all of the information type indicated by the first information (also referred to as a parameter item). For the same type of information, the specific value of the information configured by the third information (which can be understood as a parameter value) may be the same as or different from the specific value of the information indicated by the first information. For example, the first information indicates that the terminal device requests to send measurement result information for the use of resource #1, and resource #1 can be understood as the specific value of information B4 indicated by the first information. The third information may indicate that the terminal device requests to send measurement result information for the use of resource #2, and resource #2 can be understood as the specific value of information B4 indicated by the third information. Resource #2 may be the same as or different from resource #1. If the terminal device receives the third information, it may use (or not use) resource #2 to send the measurement result information.
[0412] In another possible implementation, after receiving the first information, the fourth network device may configure certain information for the terminal device using the third information. This information may not be indicated by the first information. For example, if the first information does not indicate the cell indicating the measurement result information (information B3), the fourth network device may indicate this information to the terminal device using the third information.
[0413] In this embodiment of the present application, the information indicated by the third information is information recommended by the fourth network device, and the terminal device may use the information indicated by the third information or not. The information indicated by the third information may or may not belong to the information indicated by the configuration information.
[0414] In one possible implementation, the terminal device may begin measuring the reference signal and / or sending measurement result information after receiving the third information for a period of time (e.g., a period of time specified in a protocol, which may be a specified number of time slots or a specified number of symbols, etc.).

The reference signal may be more closely matched to the reference signal that the terminal device actually needs to measure, for example, the reference signal may have the characteristics of the reference signal that the terminal device requests to measure. In the embodiment of the present application, the second network device and the first network device may be the same network device, or two devices of the same physical device. The second network device may obtain the first information, for example, the second network device may obtain the first information through signaling interaction with the first network device, or the second network device may obtain the first information without signaling interaction with the first network device.

[0420] Step 305: The terminal device measures at least one reference signal and obtains at least one measurement result information.
[0421] The content of step 305 can refer to the content of the aforementioned step 203 and will not be repeated here.
[0422] Step 306: The terminal device sends the second information via the third cell.
[0423] Correspondingly, the third network device receives the second information through the third cell.
[0424] The second information includes at least one piece of measurement result information.
[0425] The content of step 306 can refer to the content of the aforementioned step 212 and will not be repeated here.

For another example, step 306 may not be executed. In this case, it can be understood that the first information is used to trigger the measurement of the reference signal. For another example, steps 304 and 305 are not executed. In this case, the measurement result information included in the second information in step 306 may be measurement result information previously measured by the terminal device, such as measurement result information obtained by the terminal device periodically measuring the reference signal.
