Abstract
Description
Technical Field
[0001] The present application relates to the field of communication technologies, and in particular, to a communication method, apparatus, and storage medium. Background Art
[0002] The fifth-generation mobile communication system (5G) can adopt high-frequency communication, that is, use signals in the ultra-high frequency band (such as 28 gigahertz (GHz)) to transmit data. A main problem of 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 adopts analog beamforming technology. By weighting the antenna array, the signal energy is concentrated within a small angular range, forming a signal similar to a light beam (referred to as an analog beam, simply beam), thereby increasing the transmission distance. Both the network device and the terminal device need to use beams for transmission. When performing uplink and downlink data transmission, the network device and the terminal device need to use specific beams for transmission. Due to reasons such as changes in the external environment or the movement of the terminal device, the quality of the beam used for signal transmission between the terminal device and the network device may decline. Therefore, the terminal device and the network device need to obtain a beam for re-adjustment for communication in order to improve the communication quality.
[0003] In one implementation, the network device configures information such as the resources of the reference signal for measurement for the terminal device. In the periodic reference signal measurement scheme, the terminal device can measure the reference signal based on the information such as the resources configured by the network device when the measurement time in each period arrives, and feedback the measurement result information to the network device. The network device configures the beam for the terminal device according to the measurement result information. In the 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 for triggering the reference signal measurement to the terminal device. The terminal device starts to perform the reference signal measurement based on the received signaling, the terminal device feedbacks the measurement result information to the network device, and the network device configures the beam for the terminal device according to the measurement result information.
[0004] It can be seen from the above solutions that when the channel quality changes, although the terminal device finds that the quality of the current serving beam has declined, the terminal device still needs to wait until the next reference signal measurement period arrives before it can start measuring the reference signal, or the terminal device needs to wait for the network device to send an instruction for triggering the reference signal measurement before it can measure the reference signal based on this instruction. Currently, these solutions will cause untimely reference signal measurement, resulting in slow beam switching, and then frequent occurrences of communication interruption. Summary of the Invention
[0005] The present application provides a communication method, apparatus, and storage medium, which are used to enable a terminal device to start measuring a reference signal more quickly, thereby reducing the occurrence of communication interruption situations.
[0006] In a first aspect, the present application provides a communication method. This method is executed by a terminal device, which can be a terminal equipment or a chip inside the terminal equipment.
[0007] The terminal device sends first information through a first cell, and the first information is used to indicate that the terminal device requests to measure the reference signal of a second cell. The terminal device receives at least one reference signal through the second cell. The terminal device measures the at least one reference signal to obtain at least one measurement result information.
[0008] It can be seen from the above solution that the terminal device can trigger the measurement of the reference signal through the first information. That is to say, in the embodiment provided in 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 solution, the terminal device does not have to wait for the reference signal measurement process triggered by the network device, that is, it does not have to wait until the next reference signal measurement period arrives to start measuring the reference signal, or it does not have to wait for the instruction sent by the network device to trigger the reference signal measurement. In this way, the subsequent beam switching process can be accelerated, thereby reducing the occurrence of communication interruption situations.
[0009] The "measurement result information" in the present application can be replaced by "reference signal measurement result information" or "measurement result". For the convenience of introduction, it is uniformly referred to as "measurement result information" in this article.
[0010] In a possible implementation manner provided in the first aspect, the terminal device determines the cell through which the terminal device sends the measurement result information, and the cell through which the terminal device sends the measurement result information includes a third cell. The terminal device sends second information through the third cell, and the second information may (or may not) include some or all of the at least one measurement result information.
[0011] In another possible implementation manner, the second information may further include measurement result information that is not obtained by the measurement of the reference signal triggered by the terminal device. The measurement result information that is not obtained by the measurement of the reference signal triggered by the terminal device includes, for example: the measurement result information obtained in the reference signal measurement process triggered by the network device, and / or, the measurement result information obtained by the terminal device periodically measuring the reference signal.
[0012] The measurement process of the reference signal triggered by the network device in this 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 for triggering reference signal measurement to the terminal device. The terminal device starts to perform reference signal measurement based on the received signaling and obtains measurement result information. This measurement result information can also be understood as the measurement result information obtained in the measurement process of the reference signal triggered by the network device.
[0013] The measurement result information obtained by the terminal device in this application through periodic measurement of the reference signal can be understood as follows: The network device configures information such as resources of the reference signal for the terminal device to measure. In a periodic reference signal measurement scheme, the terminal device can measure the reference signal based on the information such as resources configured by the network device when the measurement time in each period arrives, and obtain measurement result information. This measurement result information can also be understood as the measurement result information obtained by the terminal device through periodic measurement of the reference signal.
[0014] In a possible implementation, the first information instructs the terminal device to request measurement of the reference signal of the second cell (for example, the first information may include information for instructing the terminal device to request measurement of the reference signal of the second cell). This implementation can also be understood as: The first information is used to instruct the terminal device to request information for measuring the reference signal of the second cell, but does not instruct the terminal device to request sending the measurement result of the reference signal of the second cell. In this case, the terminal device can trigger measurement of the reference signal (for example, perform subsequent measurement of the reference signal), and the terminal device does not trigger sending of the measurement result information (for example, does not send the measurement result information); or, the terminal device can trigger measurement of the reference signal (for example, perform subsequent measurement of the reference signal), and the terminal device also triggers sending of the measurement result information (for example, sends the second information).
[0015] In another possible implementation, the first information is further used to instruct the terminal device to request sending the measurement result of the reference signal of the second cell (for example, the first information may further include information for instructing the terminal device to request sending the measurement result of the reference signal of the second cell). In this case, the terminal device can trigger measurement of the reference signal (for example, perform subsequent measurement of the reference signal), and the terminal device also triggers sending of the measurement result information (for example, sends the second information).
[0016] 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 a reference signal, it is possible that the current beam quality of the second cell is already 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, it is very likely that the second network device will not receive this information, resulting in the failure of the reference signal measurement process requested by the terminal device. When the first cell can be different from the second cell, that is, the cell through which the terminal device sends information for requesting measurement of the reference signal of the second cell can be a cell other than the second cell, thereby improving the success rate of the terminal device's request for reference signal measurement this time.
[0017] In another possible implementation provided in the first aspect, the first cell and the second cell may also be the same, thereby improving the flexibility of the solution.
[0018] In a second aspect, the present application provides a communication method. This method is executed by a terminal device, which can be a terminal device or a chip inside the terminal device.
[0019] The terminal device sends first information through the first cell, and the first information is used to indicate that the terminal device requests to send measurement result information. The second information is sent through the third cell, and the second information includes at least one measurement result information.
[0020] In the implementation provided in the second aspect, the measurement result information included in the second information may include: measurement result information obtained from reference signal measurement triggered by the terminal device, and / or measurement result information obtained from reference signal measurement triggered by the network device.
[0021] In the implementation provided in the second aspect, the terminal device may trigger the sending process of the measurement result information through the first information. That is to say, the terminal device can trigger the sending of the measurement result information, and the terminal device does not have to wait for the sending process of the measurement result information triggered by the network device. The measurement result information included in the second information may include measurement result information obtained during the measurement process of the reference signal triggered by the network device and / or the terminal device.
[0022] In a possible implementation provided in the first aspect and / or the second aspect, the first information includes at least one of the following: information for indicating the resource of a reference signal; information for indicating a second cell; indication information of a cell for sending measurement result information; indication information of a resource for sending measurement result information; and 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. In this way, the terminal device can actively send some information it needs, so as to inform the network device side of its own requirements, so that the network device can subsequently configure a reference signal that better meets the requirements of the terminal device. In this application, the "indication information of a cell for sending measurement result information" can also be replaced with the "information for indicating the cell for sending measurement result information", and the "indication information of a resource for sending measurement result information" in this application can also be replaced with the "information for indicating the resource for sending measurement result information".
[0023] In a possible implementation 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 by the terminal device simultaneously; 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 resources associated with N transmission and reception points, where N is a positive integer. In this way, the terminal device can actively send some information it needs, so as to inform the network device side of its own requirements, so that the network device can subsequently configure a reference signal that better meets the requirements of the terminal device.
[0024] In a possible implementation provided in the first aspect and / or the second aspect, the terminal device determines a first resource. The first resource is used for sending information requesting measurement of a reference signal, and / or, the first resource is used for sending information requesting to send measurement result information of a reference signal. The terminal device sends the first information through a first cell on the first resource. In this way, the terminal device can inform the network device side of the purpose of the first information through the resource occupied by the first information, and the network device side can determine the content indicated by the first information through the resource occupied by the received first information. In this way, the signaling overhead of the first information can be saved.
[0025] In a possible implementation provided by the first aspect and / or the second aspect, the terminal device receives configuration information, and the terminal device determines a first resource according to 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, where the resource of the reference signal includes the resource occupied by the reference signal that the terminal device requests to measure; information for indicating the second cell; indication information of the cell for sending the measurement result information; indication information of the resource for sending the measurement result information; and 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. The network device side can configure some information for the terminal device through the configuration information, and these information can be used for the terminal device to trigger the measurement of the reference signal and / or the sending process of the measurement result information. Subsequently, the terminal device can select from these information in the process of triggering the measurement of the reference signal and / or the sending process of the measurement result information.
[0026] In a possible implementation provided by the first aspect and / or the second aspect, the configuration information further includes information for indicating an association relationship between any of the following: the first resource, the second cell, the resource of the reference signal, the cell for sending the measurement result information, the resource for sending 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. In this way, the terminal device can subsequently send one of the multiple associated information, so that the network device side can determine other information based on one piece of information, thereby achieving the effect of saving signaling overhead.
[0027] In a possible implementation provided by the first aspect and / or the second aspect, the information for indicating the resource of the reference signal includes at least one of the following: information for indicating the trigger state; information for indicating the channel state information reporting configuration; index information of the synchronization signal block, where the reference signal resource belongs to the resource associated with the index information of the synchronization signal block; identification of the reference signal resource; identification of the resource set corresponding to the reference signal resource; and identification of the resource configuration corresponding to the reference signal resource. The resource of the reference signal belongs to the resource associated with the trigger state, and the cell corresponding to the reference signal resource 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 resource of the reference signal belongs to the resource associated with the channel state information reporting configuration, and the cell corresponding to the reference signal resource associated with the channel state information reporting configuration includes the second cell, and the cell corresponding to the channel state information reporting configuration is different from or the same as the second cell. This can improve the flexibility and compatibility of the solution.
[0028] In the embodiments of the present application, the information for indicating the resources of the reference signal may further indicate other information. It can also be understood that the multiple pieces of information included in the above configuration information may be the same piece of information, and the multiple pieces of information included in the first information may be the same piece of information. For example, the first information and / or the configuration information includes information for indicating the trigger state, and this information for indicating the trigger state can be understood as the information for indicating the resources of the reference signal, or can be understood as the information for indicating the second cell. Another example, the first information and / or the configuration information includes information for indicating the channel state information reporting configuration, and this information for indicating the channel state information reporting configuration can be understood as the information for indicating the resources of the reference signal, or can be understood as the information for indicating the second cell.
[0029] In a possible implementation manner provided in the first aspect and / or the second aspect, the terminal device may further receive the third information through the 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. Among them, the third information is used to indicate successful reception 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 the measurement result information. In this solution, after the terminal device sends the first information, it may further receive the third information, and then can determine whether the content requested by the first information is agreed according to the third information. Or, the terminal device determines, based on the third information, what information (or parameters) associated with the measurement of the reference signal triggered by the terminal device and / or the sending process of the measurement result information are.
[0030] 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 reporting configuration; indication information of the cell for sending the measurement result information; indication information of the resources for sending the measurement result information; information for 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 reporting configuration includes the second cell, the cell corresponding to the channel state information reporting configuration is different from or the same as the second cell, and the cell corresponding to the channel state information reporting 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 can consider using this information in the subsequent process.
[0031] In a possible implementation manner provided in the first aspect and / or the second aspect, the information for indicating the trigger state includes: an identifier of the trigger state, and / or, an identifier of a cell corresponding to the trigger state. This can improve the flexibility of the solution. For example, since the information for indicating the trigger state further includes the cell corresponding to the trigger state, the cell for sending the information for 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 deteriorates, the present application can also improve the reception success rate of the information for indicating the trigger state.
[0032] In a possible implementation manner provided in the first aspect and / or the second aspect, the information for indicating the channel state information reporting configuration includes: an identifier of the channel state information reporting configuration, and / or, an identifier of a cell corresponding to the channel state information reporting configuration. This can improve the flexibility of the solution. For example, since the information for indicating the channel state information reporting configuration further includes the cell corresponding to the channel state information reporting configuration, the cell for sending the information for indicating the channel state information reporting configuration can be different from the cell corresponding to the channel state information reporting configuration. Subsequently, when the communication quality of the cell corresponding to the channel state information reporting configuration deteriorates, the present application can also improve the reception success rate of the information for indicating the channel state information reporting configuration.
[0033] In a possible implementation manner provided in the first aspect and / or the second aspect, when the fourth cell is different from the cell corresponding to the trigger state and / or the channel state information reporting configuration, the priority of the terminal device for sending the measurement result information is lower than that of the measurement result information sending process associated with the trigger state information and / or the channel state information reporting configuration corresponding to the fourth cell.
[0034] It can also be understood that the priority of the terminal device for sending the measurement result information associated with the trigger state and / or the channel state information of other cells triggered by the fourth cell is lower than that of the measurement result information associated with the trigger state and / or the channel state information of the fourth cell. It can also be understood that the priority of the terminal device for sending the measurement result information associated with the trigger state and / or the channel state information for cross-cell scheduling is lower than that of the measurement result information associated with the trigger state and / or the channel state information for intra-cell scheduling. In this way, the sending of the measurement result information associated with cross-cell scheduling will not cause significant interference to the sending of the measurement result information associated with intra-cell scheduling.
[0035] In a possible implementation provided in the first aspect and / or the second aspect, when the first information is further used to indicate the measurement result information to be sent, the priority of the terminal device to send 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 include, for example, the aperiodic and / or semi-persistent measurement result information sending processes triggered by the network device. The priority of the terminal device to send the measurement result information is lower than the sending process of the measurement result information obtained by the terminal device through periodic measurement of the reference signal.
[0036] It can also be understood that the priority of sending the measurement result information associated with the reference signal measurement and / or the measurement result information sending process triggered by the terminal device is lower than: the sending of the measurement result information associated with the reference signal measurement and / or the measurement result information sending process triggered by the network device. 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.
[0037] In a third aspect, the present application provides a communication method. This method is executed by a first network device, and the first network device may be a network device or a chip inside the network device.
[0038] In this method, the first network device receives first information through a first cell, and the first information is used to indicate that the terminal device requests to measure the reference signal of a second cell. The first network device determines that the terminal device requests to measure the reference signal of the second cell based on the first information.
[0039] It can be seen from the above solution that the terminal device can trigger the measurement of the reference signal through the first information. That is to say, the terminal device can trigger the measurement of the reference signal. The terminal device does not have to wait for the reference signal measurement process triggered by the network device, that is, it does not have to wait until the next reference signal measurement period arrives to start measuring the reference signal, or it does not have to wait for the instruction issued by the network device to trigger the reference signal measurement. In this way, the subsequent beam switching process can be accelerated, and then the occurrence of communication interruption can be reduced.
[0040] For the relevant content of the first information and the information included in the first information, as well as other descriptions and beneficial effects, reference can be made to the relevant descriptions of the possible implementations of the foregoing first aspect and second aspect, and details will not be repeated here.

[0042] In this method, a first network device receives first information through a first cell, and the first information is used to instruct a terminal device to request to send measurement result information. The first network device determines that the terminal device requests to send measurement result information based on the first information. The first information in the fourth aspect and the first information in the foregoing third aspect may be two different first information, or the same first information.
[0043] It can be seen from the above solution that the terminal device can trigger the sending process of measurement result information through the first information. That is to say, the terminal device can trigger the sending of measurement result information, and the terminal device does not have to wait for the sending process of measurement result information triggered by the network device. The measurement result information included in the second information may include the measurement result information obtained in the measurement process of the reference signal triggered by the network device and / or the terminal device.

[0046] In this solution, the second network device receives second information through a second cell to send a reference signal.
[0047] The cell where the terminal device sends the first information and the cell where the reference signal is measured may be the same or different. In this way, the terminal device can trigger the measurement of the reference signal in the same cell or trigger the measurement of the reference signal across cells.
[0048] For the relevant content of the second information, as well as other descriptions and beneficial effects, reference can be made to the relevant descriptions of the possible implementation manners in the foregoing first aspect and second aspect, and details are not described herein again.

[0050] In this solution, the third network device receives second information through a third cell.
[0051] The second information may include measurement result information, and the cell for sending the measurement result information can be set separately. For example, a cell with less load can be set, or a cell with better communication quality can be set to send the measurement result information. This can improve the success rate of receiving the measurement result information and also balance the network load.
[0052] For the related content of the second information, as well as other descriptions and beneficial effects, reference can be made to the related descriptions of the possible implementation manners of the foregoing first aspect and second aspect, which will not be elaborated herein.

The fourth network device may be the same as or different from the first network device. The fourth network device may be the same as or different from the fifth network device.
[0054] In this solution, the fourth network device sends the third information through a fourth cell.
[0055] During the measurement of the reference signal triggered by the terminal device and / or the process of sending the measurement result information, the fourth network device may also send information through the fourth cell to indicate the information required by the terminal device in subsequent processes. For example, the terminal device determines whether the content requested by itself through the first information is approved according to the third information. Or, the terminal device determines, based on the third information, what information (or parameters) associated with the process of measuring the reference signal triggered by the terminal device and / or sending the measurement result information are.
[0056] For the related content of the third information, as well as other descriptions and beneficial effects, reference can be made to the related descriptions of the possible implementation manners of the foregoing first aspect and second aspect, which will not be elaborated herein.

[0086] Before introducing the present application, some terms in the embodiments of the present application are briefly explained to facilitate the understanding of those skilled in the art.
[0087] (1) Reference signal.
[0088] The reference signal in the embodiment of the present application may include (or be) any one or more of channel state information (CSI) reference signal (RS) (the channel state information reference signal may also be denoted as CSI-RS), synchronization signal block (SSB), synchronization signal / physical layer broadcast channel block (SS / PBCH block), demodulation reference signal (DMRS), tracking reference signal (TRS), phase tracking reference signal (PTRS), cell reference signal (CRS), and sounding reference signal (SRS). In the embodiment of the present application, SSB and SS / PBCH block can be replaced with each other.
[0089] (2) Resource.
[0090] In the protocol, the term "beam" is not directly used to characterize the beam, but other ways are used to implicitly describe the operations related to the beam. For example, in beam measurement, there is a corresponding relationship between the beam and the resource (the network device uses a beam to send its corresponding resource), and the terminal device measuring the quality of the resource is equivalent to measuring the quality of the beam. The resource in the embodiment of the present application may include, for example, the resource of the reference signal.
[0091] The resource in the embodiment of the present application may include at least one of time domain resource or frequency domain resource, etc.
[0092] Time domain resources may include at least one of a radio frame, a subframe, a slot, a mini slot, or an orthogonal frequency division multiplexing (OFDM) symbol. Among them, one radio frame may include multiple subframes, one subframe may include one or more slots, and one slot may include at least one symbol. Alternatively, one radio frame may include multiple slots, and one slot may include at least one symbol. It should be noted that in the embodiments of this application, an OFDM symbol may also be simply referred to as a symbol.
[0093] Frequency domain resources may include at least one of a resource element (RE), a resource block (RB), a channel, a sub channel, a carrier, or a bandwidth part (BWP). In the embodiments of this application, a channel may also be equivalently replaced by a resource block set (RBset), and the frequency domain bandwidth of an RB set may be 20 megahertz (MHz).
[0094] (3) Beam.
[0095] The manifestation of a beam in the new radio (NR) protocol may be a spatial domain filter, or a spatial filter, or a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, or quasi-colocation (QCL) information, a QCL assumption, a QCL indication, etc. A beam may be indicated by a transmission configuration indicator state (TCI-state) parameter or by a spatial relationship parameter.
[0096] Therefore, in the present application, the beam can be replaced with an airspace filter, a spatial filter, an airspace parameter, a spatial parameter, an airspace setting, a spatial setting, QCL information, a QCL hypothesis, a QCL indication, a TCI-state (downlink TCI-state, uplink TCI-state), a spatial relationship, etc. The above terms are also equivalent to each other. The beam can also be replaced with other terms representing a beam, which is not limited in the present application.
[0097] The beam for transmitting a signal can be referred to as a transmission beam (Tx beam), or can also be referred to as a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, or a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting. The downlink transmission beam can be indicated by the TCI-state.
[0098] The beam for receiving a signal can be referred to as a reception beam (Rx beam), or can also be referred to as 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 transmission beam can be indicated by a spatial relationship, or an uplink TCI-state, or an SRS resource (indicating the transmission beam using the SRS). Therefore, the uplink beam can also be replaced with an SRS resource.
[0099] The transmission beam can refer to the distribution of signal strength formed in different directions in space after the signal is transmitted by the antenna, and the reception beam can refer to the signal strength distribution of the wireless signal received by the antenna in different directions in space.
[0100] In addition, the beam can be a wide beam, a narrow beam, or other types of beams. The technology for forming the beam can be beamforming technology or other technologies. Specifically, the beamforming technology can be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology, etc.
[0101] Generally, a beam is associated with a resource. For example, when performing beam measurement, the network device measures different beams through different resources, and the terminal device feeds back the measured resource quality, so that the network device knows the quality of the associated beam. During data transmission, the beam information is also indicated through its associated resource. For example, the network device uses the TCI field in the downlink control information (DCI) to indicate the beam information of the physical downlink sharing channel (PDSCH) of the terminal device.
[0102] Optionally, multiple beams with the same or similar communication characteristics are regarded as one beam. One beam can include one or more antenna ports for transmitting data channels, control channels, sounding signals, etc. One or more antenna ports forming one beam can also be regarded as an antenna port set.
[0103] In the embodiments of this application, if not otherwise specified, the beam refers to the transmission beam of the network device. In beam measurement, each beam of the network device is associated with a resource, so the beam associated with the resource can be uniquely identified by the index of the resource.
[0104] (4) TCI-state (used to indicate the downlink beam).
[0105] The network device can generate different beams pointing to different transmission directions. During downlink data transmission, when the network device sends data to the terminal device using a specific beam, it needs to inform the terminal device of the transmission beam information it uses, so that the terminal device can use the receiving beam associated with the transmission beam to receive the data sent by the network device.
[0106] In the 3GPP R15 / R16 protocol, the network device uses the TCI field in DCI to indicate the relevant information of the transmission beam it adopts to the terminal device. Specifically, the size of the TCI field is 3 bits, which can specifically represent 8 different field values (codepoints). Each value of the TCI field is associated with an index of a TCI-state, and this TCI-state index can uniquely identify a TCI-state. The TCI-state in the embodiments of this application can also be written as TCI state. The TCI-state includes several parameters, and the relevant information of the transmission beam can be determined through these parameters. The TCI-state is configured by the network device for each terminal device, and the structure of the TCI-state is as Figure 1 shown. Each TCI-state includes an index TCI-state identifier of itself and two QCL information (QCL information, QCL-Info). Each QCL-Info includes a cell field and a bandwidth part (bwp) identifier, which respectively indicate which cell's which bandwidth this TCI-state is applied to, that is, different cells or different bandwidths of the same cell can be configured with different QCL-Info. The QCL-Info also includes a reference signal, which is used to indicate which reference signal resource forms a QCL relationship with.
[0107] In the R15 / R16 protocol, the term "beam" generally does not appear directly, and the beam is generally replaced by other terms. For example, in data transmission and channel measurement, the beam is associated with the reference signal resource, and one beam is associated with one reference signal resource. Therefore, when it is said here which reference signal resource forms a QCL relationship, it actually means which beam forms a QCL relationship. The QCL relationship means that two reference signal resources (or two antenna ports, and the antenna port and the reference signal resource are also in one-to-one association) have some same spatial parameters. Specifically, which spatial parameters are the same depends on the type of this QCL-Info, that is, another field qcl-Type of the QCL-Info. The qcl-Type can have four values {typeA, typeB, typeC, typeD}. Taking typeD as an example, typeD means that two reference signal resources have the same spatial reception parameter information, that is, two beams have the same reception beam. At most only one of the two QCL-Info included in the TCI-state can be of TypeD.
[0108] (5) Spatial relation (for indicating the uplink beam).
[0109] In the current protocol, the transmission beam for uplink transmission is indicated by a spatial relationship, whose function is similar to that of the TCI-state and is used to inform the terminal device which transmission beam to use for uplink transmission.
[0110] The spatial relationship also needs to be configured first through radio resource control (RRC) signaling. The RRC signaling can include the id of the spatial relationship, the cell id, the target reference signal resource, the path loss measurement reference signal, the power control parameter, etc. Among them, the target reference signal resource (which can be one of SRS / SSB / CSI-RS) is used to indicate the associated uplink beam. If the uplink transmission uses spatial relationship #1 and this spatial relationship #1 includes a target reference signal resource #2, it means that the transmission beam used for this uplink transmission is the transmission / reception beam of this target reference signal. For example, when the target reference signal resource is the uplink resource SRS, it means that the transmission beam used for uplink transmission is the transmission beam of this SRS (the transmission beam of this SRS is known). Another example is that when the target reference signal resource is a downlink resource such as SSB / CSI-RS, it means that the transmission beam used for uplink transmission is the reception beam of this SSB / CSI-RS (the reception beam of this SSB / CSI-RS is known).
[0111] The network device can configure multiple spatial relationships for the terminal device. Then, one of them is activated through a media access control control element (MAC CE) for the associated data transmission. Uplink transmission includes the physical uplink control channel (PUCCH), SRS, the physical uplink shared channel (PUSCH), etc., all of which require an associated spatial relationship. The spatial relationship of the PUCCH is indicated by MAC CE signaling. The spatial relationship of the SRS is also indicated by MAC CE signaling. When the PUSCH is transmitted, it is associated with a specific SRS and is transmitted using the spatial relationship of this SRS.
[0112] Figure 1 An exemplary schematic diagram of the architecture of a communication system 1000 to which the embodiments of the present application are applicable is shown. As Figure 1 shown, Figure 1 is a schematic diagram of the architecture of the communication system 1000 to which the embodiments of the present application are applied. As Figure 1As shown in the figure, the communication system includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 1000 may further include the Internet 300. Among them, the RAN 100 includes at least one RAN node (such as 110a and 110b in Figure 1 , collectively referred to as 110), and may further include at least one terminal (such as 120a - 120j in Figure 1 , collectively referred to as 120). The RAN 100 may further include other RAN nodes. For example, wireless relay devices and / or wireless backhaul devices ( Figure 1 not shown in the figure). The terminal 120 is connected to the RAN node 110 wirelessly, and the RAN node 110 is connected to the core network 200 wirelessly or wiredly. The core network devices in the core network 200 and the RAN nodes 110 in the RAN 100 may be independent different physical devices, or the same physical device integrating the logical functions of the core network devices and the logical functions of the RAN nodes. Terminals can be connected to each other, and RAN nodes can be connected to each other, either wiredly or wirelessly.
[0113] The RAN 100 may be an evolved universal terrestrial radio access (E-UTRA) system, an NR system, and a future wireless access system defined in the 3rd generation partnership project (3GPP). The RAN 100 may also include two or more different wireless access systems as described above. The RAN 100 may also be an open RAN (O-RAN).
[0114] In the embodiments of the present application, the network devices involved may be RAN nodes. An RAN node, also known as a radio access network device, an RAN entity, or an access node, is used to help terminals access the communication system wirelessly. In one application scenario, the RAN node may be a base station, an evolved NodeB (eNodeB), a TRP, a next generation NodeB (gNB) in the 5th generation (5G) mobile communication system, a next generation NodeB in the 6th generation (6G) mobile communication system, or a base station in a future mobile communication system. The RAN node may be a macro base station (such as 110a in Figure 1 ), or a micro base station or an indoor station (such as 110b in Figure 1 ), or a relay node or a donor node.
[0115] In another application scenario, the wireless access of a terminal can be assisted by the cooperation of multiple RAN nodes, and different RAN nodes respectively implement some functions of the base station. For example, the RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). Here, the CU completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete some or all of the functions of the physical layer. For the specific descriptions of the above respective protocol layers, reference can be made to the relevant technical specifications of 3GPP. The RU can be used to implement the functions of receiving and transmitting radio frequency signals. The CU and the DU can be two independent RAN nodes, or can be integrated in the same RAN node, for example, integrated in the baseband unit (BBU). The RU can be included in the radio frequency device, for example, included in the remote radio unit (RRU) or the active antenna unit (AAU). The CU can be further divided into two types of RAN nodes, namely CU-control plane and CU-user plane.
[0116] In different systems, RAN nodes may have different names. For example, in the O-RAN system, the CU can be called an open CU (O-CU), the DU can be called an open DU (O-DU), and the RU can be called an open RU (O-RU). The central unit control plane (CU-CP) can also be called an open central unit control plane (O-CU-CP), and the central unit user plane (CU-UP) can also be called an open central unit user plane (O-CU-UP). The RAN nodes in the embodiments of this application can be implemented in the form of software modules, hardware modules, or a combination of software modules and hardware modules. For example, an RAN node can be a server loaded with the corresponding software module. The embodiments of this application do not limit the specific technologies and specific device forms adopted by the RAN nodes. For the convenience of description, in the following text, a base station is used as an example of an RAN node for description.
[0117] A terminal is a device with wireless transceiver functions that can send signals to a base station or receive signals from a base station. A terminal can also be called 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, remote medical treatment, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, etc. A terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver functions, a wearable device, a vehicle, an airplane, a ship, a robot, a robotic arm, a smart home device, etc. The embodiments of this application do not limit the specific technologies and specific device forms adopted by the terminals.
[0118] Base stations and terminals can be fixed in position or movable. Base stations and terminals can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed on airplanes, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.
[0119] The roles of base stations and terminals can be relative. For example, Figure 1The helicopter or drone 120i in it can be configured as a mobile base station. For the terminals 120j accessing the radio access network 100 through 120i, 120i is the base station; but for the base station 110a, 120i is the terminal, that is, the communication between 110a and 120i is through the radio air interface protocol. Of course, the communication between 110a and 120i can also be through the interface protocol between base stations. At this time, relative to 110a, 120i is also the base station. Therefore, both the base station and the terminal can be uniformly referred to as communication devices. Figure 1 110a and 110b in it can be referred to as communication devices with base station functions. Figure 1 120a - 120j in it can be referred to as communication devices with terminal functions.
[0120] The communication between the base station and the terminal, between the base station and the base station, and between the terminal and the terminal can be carried out through the authorized spectrum, or through the unlicensed spectrum, or through both the authorized spectrum and the unlicensed spectrum at the same time; it can communicate through the spectrum below 6 gigahertz (GHz), or through the spectrum above 6 GHz, or can also use the spectrum below 6 GHz and the spectrum above 6 GHz at the same time. The embodiments of this application do not limit the spectrum resources used for wireless communication.
[0121] In the embodiments of this application, the functions of the base station can also be executed by modules (such as chips) in the base station, or by a control subsystem including base station functions. The control subsystem including base station functions here can be the control center in the above application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal can also be executed by modules (such as chips or modems) in the terminal, or by a device including terminal functions.
[0122] In this application, the base station sends downlink signals or downlink information to the terminal, and the downlink information is carried on the downlink channel; the terminal sends uplink signals or uplink information to the base station, and the uplink information is carried on the 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 that has established a wireless connection with the terminal is called the serving cell of this terminal. When the terminal communicates with this serving cell, it will also be interfered by the signals from neighboring cells.
[0123] The communication between the access network device and the terminal device can follow a certain protocol layer structure. Exemplarily, the protocol layer structure can include a control plane protocol layer structure and a user plane protocol layer structure. For example, the control plane protocol layer structure can include at least one of the following: radio resource control (RRC) layer, packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, media access control (MAC) layer, or physical (PHY) layer, etc. For example, the user plane protocol layer structure can include at least one of the following: service data adaptation protocol (SDAP) layer, PDCP layer, RLC layer, MAC layer, or physical layer, etc.
[0124] The access network device can include a central unit (CU) and a distribute unit (DU). This design can be referred to as the separation of CU and DU. Multiple DUs can be centrally controlled by one CU. As an example, the interface between the CU and the DU is called the F1 interface. Among them, the control plane (CP) interface can be F1-C, and the user plane (UP) interface can be F1-U. The embodiments of this application do not limit the specific names of each interface. The CU and the DU can be divided according to the protocol layers of the wireless network: for example, the functions of the PDCP layer and the protocol layers above it (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; or for another example, the functions of the protocol layers above the PDCP layer are set in the CU, and the functions of the PDCP layer and the protocol layers below it are set in the DU, without limitation.
[0125] The above division of the processing functions of the CU and the DU according to the protocol layers is only an example, and it can also be divided in other ways. For example, the CU or the DU can be divided into functions with more protocol layers, or for another example, the CU or the DU can be divided into partial processing functions of the protocol layers. For example, some functions of the RLC layer and the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the protocol layers below the RLC layer are set in the DU. For another example, the functions of the CU or the DU can be divided according to the service type or other system requirements, such as dividing by delay, setting the functions that need to meet the delay requirements in the DU, and setting the functions that do not need to meet the delay requirements in the CU.
[0126] Optionally, the CU may have one or more functions of the core network.
[0127] Optionally, the radio unit (RU) of the DU can be remotely deployed. The RU has radio frequency functions. Exemplarily, the DU and the RU can be divided at the PHY layer. For example, the DU can implement the high-layer functions in the PHY layer, and the RU can implement the 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 function. When used for reception, the functions of the PHY layer may include at least one of the following: CRC check, channel decoding, descrambling, demodulation, de-layer mapping, channel detection, resource demapping, physical antenna demapping, or radio frequency reception function. The high-layer functions in the PHY layer may include a part of the functions of the PHY layer, and this part of the functions is closer to the MAC layer; the low-layer functions in the PHY layer may include another part of the functions of the PHY layer, for example, this part of the functions is closer to the radio frequency function. For example, the high-layer functions in the PHY layer may include adding CRC bits, channel coding, rate matching, scrambling, modulation, and layer mapping, and the low-layer functions in the PHY layer may include precoding, resource mapping, physical antenna mapping, and radio frequency transmission function; or, the high-layer functions in the PHY layer may include adding CRC bits, channel coding, rate matching, scrambling, modulation, layer mapping, and precoding, and the low-layer functions in the PHY layer may include resource mapping, physical antenna mapping, and radio frequency transmission function. For example, the high-layer functions in the PHY layer may include CRC check, channel decoding, descrambling, decoding, demodulation, and de-layer mapping, and the low-layer functions in the PHY layer may include channel detection, resource demapping, physical antenna demapping, and radio frequency reception function; or, the high-layer functions in the PHY layer may include CRC check, channel decoding, descrambling, decoding, demodulation, de-layer mapping, and channel detection, and the low-layer functions in the PHY layer may include resource demapping, physical antenna demapping, and radio frequency reception function.
[0128] Optionally, the functions of the CU can be further divided to separate the control plane and the user plane and implement them through different entities. The separated entities are the control plane CU entity (i.e., the CU-CP entity) and the user plane CU entity (i.e., the CU-UP entity). The CU-CP entity and the CU-UP entity can be respectively connected to the DU. In the embodiments of the present application, an entity can be understood as a module or a unit, and its existence form can be a hardware structure, a software module, or a combination of a hardware structure and a software module, without limitation.
[0129] Optionally, any one of the foregoing CU, CU-CP, CU-UP, DU, and RU may be a software module, a hardware structure, or a combination of a software module and a hardware structure, without limitation. Among them, the forms of existence of different entities may 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 of description, all possible combination forms will not be listed one by one here. These modules and the methods they execute are also within the protection scope of the embodiments of the present application. For example, when the method of the embodiments of the present application is executed by an access network device, it may be specifically executed by at least one of CU, CU-CP, CU-UP, or DU.
[0130] Based on Figure 1 the embodiments shown, Figure 2A FIG. exemplarily shows a possible schematic flow diagram of a communication method provided by the embodiments of the present application. Figure 2A The terminal device in Figure 1 may be the terminal device shown in the foregoing Figure 2A or a chip inside the terminal device, Figure 1 The first network device and / or the second network device in
[0131] may be the network device (such as a RAN node, such as CU or DU) shown in the foregoing Figure 2A or a chip in the network device (such as a chip in a RAN node, such as a chip in CU or DU). Figure 2A is introduced below in conjunction with the accompanying
[0132] Step 201, the terminal device sends first information through a first cell.
[0133] Correspondingly, the first network device receives the first information through the first cell.
[0134] The first information is used to instruct the terminal device to request a measurement of a reference signal. In the embodiments of the present application, "the terminal device requests a measurement of a reference signal" may be replaced by "the terminal device triggers a reference signal measurement" or "the terminal device initiates a reference signal measurement". For example, the terminal device may request a measurement of a cell (such as a second cell). In this case, it may also be understood that the first information is used to instruct the terminal device to request a measurement of the reference signal of the second cell.
[0135] Step 202, the second network device sends at least one reference signal through a second cell.
[0136] Correspondingly, the terminal device receives at least one reference signal through the second cell.
[0137] In the embodiments of the present application, the first cell and the second cell may be different or the same, which can improve the flexibility of the solution. In a possible implementation, when the terminal device determines that the second cell needs to measure the reference signal, it is possible that the current beam quality of the second cell is already poor. In this case, if the terminal device still sends the information for requesting the measurement of the reference signal of the second cell through the second cell, it is very likely that the second network device will not receive this information, resulting in the failure of the reference signal measurement process requested by the terminal device. However, in a solution provided by the embodiments 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 the 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.
[0138] The fourth cell and the third cell that will be involved later in the embodiments of the present application. Any two of the first cell, the second cell, the fourth cell, and the third cell in the embodiments of the present application may be the same or different.
[0139] In the embodiments of the present application, the first network device may be the network device corresponding to the first cell. In the embodiments of the present application, the second network device may be the network device corresponding to the second cell. The first network device and the second network device in the embodiments of the present application 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 (CC) under the first network device respectively.
[0140] The third network device, the fourth network device, and the fifth network device that will be involved later in the embodiments of the present application. The third network device may be the network device corresponding to the third cell, and the fourth network device may be the network device corresponding to the fourth cell. The cell corresponding to any network device in the embodiments of the present application can be understood as that the network device can provide services for the cell, or it can be understood that the cell belongs 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) may correspond to one or more cells.
[0141] Any one of the first cell, the second cell, the third cell, and the fourth cell in the embodiments of the present application may be, for example: a serving cell, a neighboring cell of the serving cell (such as a cell corresponding to an additional physical cell identifier (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).
[0142] In the embodiments 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 respectively associated with different physical cell identifiers (PCIs). For the sake of distinction, the PCI of the non-serving cell may be referred to as an additional PCI.
[0143] Any two of the first network device, the second network device, the fourth network device, the third network device, and the fifth network device in the embodiments of the present application 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. Any two of the first network device, the second network device, the fourth network device, the third network device, and the fifth network device in the embodiments of the present application may be respectively located in two different physical devices, or may be located in the same physical device. When any two of the first network device, the second network device, the fourth network device, and the third network device in the embodiments 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 component carriers (CCs) under the same base station.
[0144] Step 203: The terminal device measures at least one reference signal to obtain at least one measurement result information.
[0145] The measurement result information in the embodiments of this application can be replaced with measurement result information, or can be replaced with any one or more pieces of information included in the measurement result information. For example, it can be replaced with channel state information (CSI), etc. The measurement result information can include reference signal receiving power (RSRP) (RSRP can also be referred to as layer 1 reference signal received power (L1-RSRP)), signal to interference plus noise ratio (SINR) (SINR can be referred to as layer 1 signal to interference plus noise ratio (L1-SINR)), channel quality indicator (CQI), precoding matrix indicator (PMI), CSI reference signal resource indicator (CRI), SSB resource indicator (SS / PBCH block resource indicator, SSBRI), layer indicator (LI), and any one or more of rank indicator (RI).
[0146] Through Figure 2A It can be seen from the provided solution that the terminal device can trigger the measurement of the reference signal through the first information. That is to say, the terminal device can trigger the measurement of the reference signal. 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 until the next reference signal measurement period arrives to start measuring the reference signal, or it does not have to wait for the instruction for triggering the reference signal measurement sent by the network device. In this way, the subsequent beam switching process can be accelerated, and then the occurrence of communication interruption can be reduced.
[0147] For example, when the channel quality changes and the terminal device finds that the quality of the current serving beam has deteriorated, the terminal device can actively send information requesting the measurement of the reference signal, without having to wait until the next reference signal measurement period arrives to start measuring the reference signal, or without having to wait for the instruction for triggering the reference signal measurement sent by the network device. In the solution provided by the embodiments of this application, since the terminal device can trigger the measurement of the reference signal, this solution can accelerate the subsequent beam switching process, and then reduce the occurrence of communication interruption.
[0148] In Figure 2A In a possible implementation provided, the terminal device determines the cell for the terminal device to send measurement result information, and the cell for the terminal device to send measurement result information includes a third cell. The terminal device sends a second piece of information through the third cell. In Figure 2A In the provided implementation, the second piece of information may (or may not) include some or all of at least one measurement result information obtained by the terminal device in step 203.
[0149] In another possible implementation, the second piece of information may also (or may not) include measurement result information obtained from measurements of reference signals not triggered by the terminal device. Measurement result information obtained from measurements of reference signals not triggered by the terminal device includes, for example: measurement result information obtained during the measurement process of reference signals triggered by the network device, and / or measurement result information obtained by the terminal device periodically measuring reference signals.
[0150] The measurement process of the reference signal triggered by the network device in this application can be understood as follows: In the reference signal measurement scheme of the AP or SP, when the network device determines that a reference signal measurement needs to be performed, the network device sends a signaling for triggering the reference signal measurement to the terminal device. The terminal device starts to perform the reference signal measurement based on the received signaling and obtains measurement result information. This measurement result information can also be understood as: measurement result information obtained during the measurement process of the reference signal triggered by the network device.
[0151] The measurement result information obtained by the terminal device periodically measuring the reference signal in this application can be understood as follows: The network device configures information such as resources of the reference signal for measurement for the terminal device. In the periodic reference signal measurement scheme, the terminal device can perform the measurement of the reference signal based on the information such as resources configured by the network device when the measurement time in each period arrives, and 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.
[0152] In a possible implementation, the first information instructs the terminal device to request a reference signal measurement of a second cell (for example, the first information may include information for instructing the terminal device to request a reference signal measurement of the second cell). This implementation can also be understood as follows: The first information is used to indicate the information for the terminal device to request a reference signal measurement of the second cell, but does not 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 does not trigger the sending of the measurement result information (for example, does not send the measurement result information); or, 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 the measurement result information (for example, sends the second information).
[0153] In another possible implementation, the first information is further used to instruct the terminal device to request to send the measurement result of the reference signal of the second cell (for example, the first information may further include information for instructing the terminal device to request 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 the measurement result information (for example, sends the second information).
[0154] Based on Figure 1 and Figure 2A the embodiments shown, Figure 2B an exemplary schematic flow diagram of a possible communication method provided by an embodiment of the present application is shown. Figure 2B The third network device in Figure 1 may be the aforementioned network device (such as a RAN node, such as a CU or a DU) or a chip in the network device (such as a chip in a RAN node, such as a chip in a CU or a DU). Figure 2B For the relevant descriptions of the terminal device, the first network device, and the third network device in Figure 2A reference may be made to the relevant descriptions in
[0155] As Figure 2B shown, the method includes step 211, step 212, and step 213. The following will be introduced in conjunction with the attached Figure 2B drawings.
[0156] Step 211, the terminal device sends the first information through the first cell.
[0157] Correspondingly, the first network device receives the first information through the first cell.
[0158] The first piece of information is used to instruct the terminal device to request the transmission of measurement result information. In the embodiments of the present application, "the terminal device requests the transmission of measurement result information" can be replaced with "the terminal device triggers the transmission of measurement result information", or replaced with "the terminal device triggers the reporting of measurement result information", or replaced with "the terminal device initiates the transmission of measurement result information", or replaced with "the terminal device initiates the reporting of measurement result information". In the embodiments of the present application, "report" and "transmit" can be replaced with each other.
[0159] Step 212, the terminal device transmits the second piece of information through the third cell.
[0160] Correspondingly, the third network device receives the second piece of information through the third cell.
[0161] The second piece of information includes at least one piece of measurement result information.
[0162] In the embodiments of the present application, the third cell and the first cell can be different or the same, which can improve the flexibility of the solution.
[0163] Through Figure 2B It can be seen from the provided solution that the terminal device can trigger the transmission process of the measurement result information through the first piece of information. That is to say, the terminal device can trigger the transmission of the measurement result information. The terminal device does not have to wait for the transmission process of the measurement result information triggered by the network device, that is, it does not have to wait until the next measurement result information transmission period arrives to start transmitting the measurement result information, or it does not have to wait for the instruction issued by the network device to trigger the transmission of the measurement result information. In this way, the subsequent beam switching process can be accelerated, and then the occurrence of communication interruption can be reduced.
[0164] For example, when the channel quality changes and the terminal device finds that the quality of the current serving beam has deteriorated, the terminal device can actively send information requesting the transmission of measurement result information, without having to wait until the next reference signal measurement period arrives to start transmitting the measurement result information, or without having to wait for the instruction issued by the network device to trigger the transmission of the measurement result information. In the solution provided by the embodiments of the present application, since the terminal device can trigger the transmission of the measurement result information, this solution can accelerate the subsequent beam switching process, and then reduce the occurrence of communication interruption.
[0165] The "transmission of measurement result information triggered by the 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", which specifically refers to the terminal device sending a first piece of information, and the first piece of information is at least used to request the transmission of measurement result information. The "transmission of measurement result information triggered by the network 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 network device", which specifically refers to the network device first sending information to the terminal device for indicating the transmission of measurement result information.
[0166] In the embodiments of the present application, the priority of the terminal device to send measurement result information is lower than that of the transmission process of measurement result information triggered by the network device. The transmission process of measurement result information triggered by the network device may include, for example, the aperiodic and / or semi-persistent transmission process of measurement result information triggered by the network device. The priority of the terminal device to send measurement result information may also be lower than that of the transmission process of measurement result information obtained by the terminal device periodically measuring the reference signal. In this way, the transmission of measurement result information triggered by the terminal device will not cause great interference to the transmission of measurement result information triggered by the network device.
[0167] For example, when the reporting of measurement result information triggered by the terminal device overlaps with the reporting of measurement result information not triggered by the terminal device (the reporting of measurement result information not triggered by the terminal device includes, for example, the reporting of measurement result information triggered by the network device or the reporting of measurement result information obtained by the terminal device periodically) on at least one OFDM symbol in the time domain of the same subcarrier, then the reporting of measurement result information triggered by the terminal device is lower than the reporting of measurement result information not triggered by the terminal device, and the multiplexing of the reporting is performed according to this priority rule or the terminal device discards the measurement result information triggered by the terminal device (that is, does not report). In a possible implementation manner, there are the following priority rules for the reporting of measurement result information:
[0168] 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
[0169] where x = 0 represents the reporting of measurement result information triggered by the network device or the reporting of measurement result information obtained by the terminal device periodically; x = 1 represents the reporting of measurement result information triggered by the terminal device.
[0170] y = 0 represents an aperiodic CSI report carried by PUSCH, y = 1 represents a semi-persistent CSI report carried by PUSCH, y = 2 represents a semi-persistent CSI report carried by PUCCH, and y = 3 represents a periodic CSI report carried by PUCCH;
[0171] k = 0 represents a CSI report carrying L1-RSRP or L1-SINR, and k = 1 represents a CSI report not carrying L1-RSRP or L1-SINR;
[0172] c represents the serving cell index;
[0173] N cells represents the maximum number of serving cells configured by a higher layer parameter (this higher layer parameter can be maxNrofServingCells);
[0174] s is the report configuration identifier (the report configuration identifier can be denoted as reportConfigID);
[0175] M s represents the maximum number of CSI report configurations configured by a higher layer parameter (this higher layer parameter can be maxNrofCSI-ReportConfigurations);
[0176] Pri iCSI (x, y, k, c, s) represents the priority, where Pri iCSI (x, y, k, c, s) the smaller the value, the higher the priority can be.
[0177] In Figure 2B the provided implementation, the first information sent by the terminal device in step 211 and the first information sent by the terminal device in step 201 can be the same first information, or can be two different first information. The first information in step 201 can also be replaced with: information for instructing the terminal device to request measurement of the reference signal. The first information in step 211 can also be replaced with: information for instructing the terminal device to request to send measurement result information.
[0178] Figure 2A and Figure 2B the implementation shown can be executed separately, that is, the terminal device can trigger the measurement of the reference signal alone. After obtaining the measurement result information, it can send the measurement result information or can not send the measurement result information. The terminal device can also trigger the sending of the measurement result information alone. 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.
[0179] In another possible implementation, Figure 2A and Figure 2B The solutions provided can be used in combination. Figure 1 , Figure 2A and Figure 2B The embodiment shown, Figure 2C A possible flow chart of a communication method provided in an embodiment of the present application is exemplified. Figure 2C Can be regarded as Figure 2A and Figure 2B In combination with the embodiment of the invention, Figure 2C For the description of the terminal device, the first network device, the second network device and the third network device, please refer to the aforementioned Figure 2A or Figure 2B The relevant description in will not be repeated here.
[0180] like Figure 2C As shown, the method includes step 201, step 202 and step 203. Figure 2A Make an introduction.
[0181] Step 221: The terminal device sends, through the first cell, information indicating that the terminal device requests measurement of a reference signal.
[0182] Correspondingly, the first network device receives, through the first cell, information indicating that the terminal device requests measurement of the reference signal.
[0183] The information for indicating that the terminal device requests measurement of a reference signal for measurement of a reference signal may be the first information sent by the terminal device in the aforementioned step 201 .
[0184] The content of step 221 can refer to the relevant description of the aforementioned step 201 and will not be repeated here.
[0185] Step 222: The terminal device sends, through the first cell, information indicating that the terminal device requests to send measurement result information.
[0186] Correspondingly, the first network device receives, through the first cell, information indicating that the terminal device requests to send measurement result information.
[0187] The information used to instruct the terminal device to request to send measurement result information may be the first information sent by the terminal device in the foregoing step 211. The information used to instruct the terminal device to request to send measurement result information and the information used to instruct the terminal device to request to measure a reference signal may be the same piece of information (in this case, step 221 and step 222 may be the same step), or two different pieces of information. The order of step 221 and step 222 may also be changed. For example, step 222 may be executed first, and then step 221. The information used to instruct the terminal device to request to send measurement result information and the information used to instruct the terminal device to request to measure a reference signal may be carried in the same message or carried in two different messages respectively.
[0188] For the content of step 222, reference may be made to the relevant description of the foregoing step 211, and details are not described herein again.
[0189] Step 223, the second network device sends at least one reference signal through the second cell.
[0190] Correspondingly, the terminal device receives at least one reference signal through the second cell.
[0191] For the content of step 223, reference may be made to the relevant description of the foregoing step 202, and details are not described herein again.
[0192] Step 224, the terminal device measures at least one reference signal to obtain at least one piece of measurement result information.
[0193] For the content of step 224, reference may be made to the relevant description of the foregoing step 203, and details are not described herein again.
[0194] Step 225, the terminal device sends the second information through the third cell.
[0195] Correspondingly, the third network device receives the second information through the third cell.
[0196] In the embodiments 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 the embodiments of the present application, the second information includes at least one piece of measurement result information. The second information may include some or all of the at least one piece of measurement result information obtained by the terminal device in step 224. Alternatively, the second information does not include any of the at least one piece of measurement result information obtained by the terminal device in step 224. For example, the measurement result information included in the second information may include the measurement result information obtained by the reference signal measurement process triggered by the network device, or the measurement result information obtained by the reference signal measurement process triggered by the terminal device before, etc.
[0197] For the content of step 225, reference may be made to the relevant description of the foregoing step 212, and details are not described herein again.
[0198] Through Figure 2C From the provided solution, it can be seen that in the embodiments of the present application, the terminal device can trigger the measurement of the reference signal and the transmission of the measurement result information through one piece of information or multiple pieces of information. In this way, the subsequent beam switching process can be accelerated, and then the occurrence of communication interruption can be reduced.
[0199] Based on Figure 1 , Figure 2A , Figure 2B and Figure 2C the provided solution, the following respectively uses Figure 3 an exemplary flowchart of a communication method provided by the embodiments of the present application is introduced. Figure 3 It can be regarded as Figure 2A , Figure 2B or Figure 2C an extended embodiment. Figure 3 For the relevant content of the terminal device, the first network device, the second network device, and the third network device involved in Figure 2A , Figure 2B or Figure 2C , reference can be made to the relevant introduction above, and details will not be repeated. Figure 3 The fourth network device and the fifth network device in Figure 1 can be the network devices (such as RAN nodes, such as CU or DU) or the chips in the network devices (such as the chips in RAN nodes, such as the chips in CU or DU) in the foregoing
[0200] The following is introduced in combination with Figure 3 . In one possible implementation manner, Figure 3 the embodiment shown in Figure 3 includes step 302, step 304, and step 305. In another possible implementation manner, Figure 3 the embodiment shown in
[0201] Step 301, the fifth network device sends configuration information.
[0202] Correspondingly, the terminal device receives the configuration information.
[0203] In one possible implementation manner, the configuration information can be sent through a Radio Resource Control (RRC) message.
[0204] 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 the resources of reference signals (information A2), information for indicating the cells that the terminal device requests to measure (information A3), indication information of the cell for sending measurement result information (information A4), indication information of the resources for sending 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).
[0205] The configuration information may also configure the association relationship (such as information A8) between any multiple of the following: scheduling resources (such as the first resource), the cells that the terminal device requests to measure (such as the second cell), the resources of reference signals, the cells for sending measurement result information, the resources for sending 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. For example, the configuration information may configure the association relationship between the scheduling resource (such as the first resource) and the trigger state. The trigger state can be understood as the information for indicating the resources of reference signals (information A2), etc., and the subsequent detailed introduction can be referred to. In this way, when the terminal device sends the first information through the first resource, 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 and will not be elaborated here for the time being.
[0206] Information A1, the information for indicating scheduling resources.
[0207] For the sake of distinction, in the embodiments of the present application, the resources for sending requests for reference signal measurement and / or requests for sending measurement result information are referred to as scheduling resources. The scheduling resources in this article can be replaced with resources, scheduling request resources, dedicated scheduling request resources, PUCCH, or PUSCH. The scheduling resources indicated by the information for indicating scheduling resources included in the configuration information can be understood as: the 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 the resources that such information can (or is allowed, or is recommended) to occupy.
[0208] The scheduling resources in the embodiments of the present application may include time domain resources and / or frequency domain resources. For example, it may include the period and offset of the scheduling resources in the time domain (and / or frequency domain).
[0209] The information for indicating scheduling resources may include, for example, one or more of the identifier of the PUCCH, the scheduling request resource identifier (which may be expressed in English as "schedulingRequestResourceId" for example), and the scheduling request identifier (which may be expressed in English as "schedulingRequestId" for example). The terminal device may determine the scheduling resources based on the information for indicating scheduling resources. For example, the terminal device may find the resources associated with the identifier of the PUCCH according to the identifier of the PUCCH, and the terminal device sends a scheduling request through this resource to request reference signal measurement and / or request to send measurement result information. The information for indicating scheduling resources may also include the identifier of the resource and / or the identifier of the resource set.
[0210] The resources (scheduling resources) for sending the information for indicating a request for reference signal measurement and the resources (scheduling resources) for sending the information for indicating a request to send measurement result information 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: the information for indicating a request for reference signal measurement, and / or, the information for indicating a request to send measurement result information. The network device may determine the purpose of the information based on whether the resources occupied by the information are scheduling request resources.
[0211] In a possible implementation, the information for indicating scheduling resources includes first resource indication information and second resource indication information. The first resource indication information is used to indicate a resource. The first resource indication information includes the identifier of the resource and / or the identifier of the resource set. The resource indicated by the first resource indication information is used to send: the information for indicating a request for reference signal measurement. The second resource indication information is used to indicate a resource. The second resource indication information may include the identifier of the resource and / or the identifier of the resource set. The resource indicated by the second resource indication information is used to send: the information for indicating a request to send measurement result information. The first resource indication information and the second resource indication information are introduced below through information A1.1 and information A1.2 respectively.
[0212] Information A1.1, the first resource indication information.
[0213] For example, if the terminal device sends information through a resource and the first network device receives the information, the first network device can determine whether the resource occupied by the information belongs to the resource indicated by the first resource indication information. If the first resource belongs to the resource indicated by the first resource indication information, the first network device can determine that the information is used to request measurement of the reference signal, or it can also be understood that: the first network device determines based on the information that the terminal device wants to trigger the measurement of the reference signal. In another possible implementation, if the first resource does not belong to the resource indicated by the first resource indication information, the first network device can determine that the information is not an information used to request measurement of the reference signal. In this implementation, the information sent by the terminal device may not require additional information to indicate the use of the information, thereby saving signaling overhead.
[0214] Information A1.2, the second resource indication information.
[0215] For example, if the terminal device sends information through a resource and the first network device receives the information, the first network device can determine whether the resource occupied by the information belongs to the resource 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 sending measurement result information, or it can also be understood that: the first network device determines based on the information that the terminal device wants to trigger the sending of measurement result 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 an information used to request sending measurement result information. In this implementation, the information sent by the terminal device may not require additional information to indicate the use of the information, thereby saving signaling overhead.
[0216] 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 measurement of the reference signal, or can also be used to send information indicating a request for sending measurement result information. Or, the information sent through the first resource requests both measurement of the reference signal and sending of measurement result information.
[0217] In the embodiments of the present application, when the first resource is subsequently involved, the information used to indicate the first resource may include, for example, the resource identifier and / or resource set identifier of the first resource. The information used to indicate the first resource may belong to the first resource indication information and / or belong to the second resource indication information. Or, it can also be understood that: the first resource is used to send information requesting measurement of the reference signal, and / or, the first resource is used to send information requesting sending of reference signal measurement result information.
[0218] Information A2, information for indicating the resources of the reference signal.
[0219] In the embodiments of the present application, the information included in the configuration information for indicating the resources of the reference signal can indicate the resources of the reference signal. These resources of the reference signal can be understood as: the resources that the reference signal requested to be measured by the terminal device can (or is allowed, or is recommended to) occupy. The terminal device can receive and measure the reference signal on the resources of the reference signal. In the embodiments of the present application, the resources of the reference signal can be replaced with the resources corresponding to the reference signal, or the resources occupied by the reference signal, etc.
[0220] In the embodiments of the present application, the resources of the reference signal can be indicated by some information. For example, the information for indicating the resources of the reference signal can include at least one of: the information for indicating the trigger state, the information for indicating the channel state information reporting configuration, the index information of the synchronization signal block, the identifier of the reference signal resource, the identifier of the resource set corresponding to the reference signal resource, and the identifier of the resource configuration corresponding to the reference signal resource. In this case, the configuration information can further include an indication of the association relationship between the scheduling resources and the information for indicating the resources of the reference signal.
[0221] The information for indicating the resources of the reference signal can specifically include various types. For example, the information for indicating the resources of the reference signal can include one or more of information A2.1, information A2.2, information A2.3, information A2.4, information A2.5, or information A2.6. Among them, information A2.1 is the information for indicating the trigger state, information A2.2 is the information for indicating the channel state information reporting configuration, information A2.3 is the index information of the synchronization signal block, information A2.4 is the identifier of the reference signal resource, information A2.5 is the identifier of the resource set corresponding to the reference signal resource, and information A2.6 is the identifier of the resource configuration corresponding to the reference signal resource.
[0222] Information A2.1, information for indicating the trigger state.
[0223] In the embodiments of the present application, the English of the trigger state can be written as "trigger state". In the embodiments of the present application, the trigger state can also be replaced with the trigger state information or the trigger state configuration information, or replaced with information. In the embodiments of the present application, for the sake of distinction, it is referred to as the trigger state.
[0224] In the embodiments of the present application, one trigger state can correspond to one cell. The cell corresponding to the trigger state involved in the embodiments of the present application can be understood as the cell to which the trigger state belongs. The cell corresponding to the trigger state can include the serving cell, such as Scell, Pcell, or PScell.
[0225] When the cell corresponding to the trigger state is the serving cell, the identifier of the cell corresponding to the trigger state can be carried in the serving cell identifier field in the configuration message, and the English name of this field can be denoted as serving cell ID.
[0226] In the embodiments of this application, the information used to indicate the trigger state may include the identifier of the cell corresponding to the trigger state. The information used to indicate the trigger state may also include other information, such as the identifier of the trigger state, etc.
[0227] For example, the information used to indicate the trigger state is the identifier of the cell corresponding to the trigger state (such as the serving cell), for example, the identifier of CC0. Then the identifier of this cell is used to indicate the trigger state corresponding to CC0. Or the identifier of this cell is used to indicate the trigger state where the corresponding cell (such as the serving cell) is CC0.
[0228] In the embodiments of this application, the trigger state can be associated with a resource or a resource set. The trigger state can be associated with the resource of the reference signal. Therefore, the information used to indicate the trigger state in the embodiments of this application can be regarded as the information used to indicate the resource of the reference signal.
[0229] Next, a form of the information that may be included in a trigger state is introduced.
[0230] For example, the configuration information may configure one or more trigger states. For example, the configuration information may configure a list of channel state information trigger states, which can be denoted as CSI-TriggerStateList, and this list may include multiple trigger states.
[0231] A trigger state may include one or more (such as no more than 16) pieces of channel state information associated report configuration information (the channel state information associated report configuration information can be denoted as CSI-AssociatedReportConfigInfo).
[0232] Among them, a piece of channel state information associated report configuration information may include a report configuration identifier (this information can be denoted as reportConfigId) and a channel resource information (the channel resource information can be denoted as resourcesForChannel). The report configuration identifier and the channel resource information in a piece of channel state information associated report configuration information can be associated.
[0233] Among them, the channel resource information may be associated with a resource set or a resource. For example, the channel resource information may be associated with a CSI-RS resource set, a non-zero power CSI-RS (NZP-CSI-RS) resource set, a zero power CSI-RS (ZP-CSI-RS) resource set, a CSI interference measurement (CSI-IM) resource set, or a CSI signal synchronization signal block (CSI-SSB) resource set. The resource set in the embodiments of the present application may be denoted as resource set.
[0234] The resource (or the resource in the resource set) associated with the channel resource information may be understood as the resource of the reference signal. Taking the example that the channel resource information is associated with a resource set, 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 the network device can find out the resource set associated with the channel resource information according to the channel resource information. The resource set associated with a piece of channel resource information may include the relevant parameters (or information) of the resource. For example, the resource set (which may also be referred to as the configuration information of the resource set) may further 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.
[0235] Multiple types of information can be configured in a resource set. For example, at least one of the following can be configured: one or more resources (such as SSB resources or CSI-RS resources), whether to repeat (the English for repetition can be written as "repetition", and "repetition" can include two states: enabled and disabled. The enabled state can be represented by the English word "on", and the disabled state can be represented by the English word "off". Whether to repeat can also be understood as whether "repetition" is in the "on" or "off" state. When "repetition" is in the "on" state, it can also be understood that the resources in the resource set are transmitted using the same downlink spatial filter. When "repetition" is in the "off" state, it can also be understood that the resources in the resource set do not need to be transmitted using the same downlink spatial filter), aperiodic triggering offset (which can be denoted in English as "aperiodicTriggeringOffset"), all NZP-CSI-RS resources in the CSI-RS resource set have the same antenna port (this meaning can also be expressed as "trs-info"), and spatial relationship information (which can be denoted as "QCL-info").
[0236] Among them, the reporting configuration identifier can be understood as an example of information used to indicate the channel state information reporting configuration. The reporting configuration identifier can also be referred to as the identifier of the channel state information reporting configuration. The reporting configuration identifier can correspond to a channel state information reporting configuration (in the embodiments of this application, the channel state information reporting configuration can be denoted as "CSI-ReportConfig". In this application, the channel state information reporting configuration can be replaced with channel state information reporting, or replaced with channel state information reporting information, or replaced with channel state information reporting configuration information, or replaced with information, etc.). A channel state information reporting configuration can include the identifier of the reporting configuration so that the terminal device or the network device can find the corresponding channel state information reporting configuration according to the identifier of the reporting configuration.
[0237] In a possible implementation, a channel state information reporting configuration may further include information indicating the cell to which the reference signal resource belongs. The reference signal resource can be the resource of the reference signal indicated in the channel resource information associated with the channel state information reporting configuration. The information indicating the cell to which the reference signal resource belongs can be carried in a field of the channel state information reporting configuration. The English name of this field can be, for example, the "carrier" field. For example, if the channel state information reporting 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 resource of the reference signal requested to be measured by the terminal device belongs is CC2. It can also be understood that the terminal device requests to measure the reference signal of CC2.
[0238] In yet another possible implementation, a channel state information reporting configuration may further include relevant parameters (or information) of measurement result information sent by a terminal device. For example, the channel state information reporting configuration may include at least one of: a reporting configuration type (which may be denoted as reportConfigType for example), a reporting quantity (which may be denoted as reportQuantity for example), group-based beam reporting (which may be denoted as groupBaseBeamReporting for example), or a channel measurement resource (which may be denoted as resourceForChannelMeasurement for example).
[0239] Information A2.2, which is used to indicate the channel state information reporting configuration.
[0240] A channel state information reporting configuration (which may be denoted as CSI-ReportConfig for example) may correspond to a cell. In the embodiments of the present application, the cell corresponding to the channel state information reporting configuration can be understood as the cell to which the channel state information reporting configuration belongs. The cell corresponding to the channel state information reporting configuration may include a serving cell, such as an Scell, a Pcell, or a PScell. When the cell corresponding to the channel state information reporting configuration is a serving cell, the identifier of the cell corresponding to the channel state information reporting configuration may be carried in the serving cell identifier field in the configuration message, and this field may be denoted as serving cell ID in English.
[0241] In the embodiments of the present application, the information used to indicate the channel state information reporting configuration may include the identifier of the cell corresponding to the channel state information reporting configuration. The information used to indicate the channel state information reporting configuration may further include other information, such as the identifier of the channel state information reporting configuration, etc.
[0242] For example, the information used to indicate the channel state information reporting configuration is the identifier of the cell corresponding to the channel state information reporting configuration (such as a serving cell), for example, the identifier of CC0. Then the identifier of this cell is used to indicate the channel state information reporting configuration corresponding to CC0. Or the identifier of this cell is used to indicate the channel state information reporting configuration corresponding to the corresponding cell (such as a serving cell) being CC0.
[0243] The information used to indicate the channel state information reporting configuration may be associated with a resource or a resource set. The channel state information reporting configuration may be associated with the resource of a reference signal. Therefore, in the embodiments of the present application, the information used to indicate the channel state information reporting configuration can be regarded as the information used to indicate the resource of the reference signal.
[0244] For example, the channel state information reporting configuration is associated with the channel resource information (which can be denoted as resourcesForChannel) in the triggering state, and the resources indicated by the channel state information reporting configuration are the resources indicated by the channel resource information.
[0245] For the relevant content of the channel state reporting configuration, channel resource information, and triggering state, refer to the relevant description in the foregoing information A2.1, which will not be elaborated here. The channel state information reporting configuration in the embodiments of the present application can be configured in the triggering state or can be configured separately, that is, not configured in the triggering state.
[0246] Information A2.3, the index information of the synchronization signal block.
[0247] The synchronization signal block in the embodiments of the present application may include an SSB. The index information of the synchronization signal block includes information for indicating the synchronization signal block.
[0248] When the index information for the synchronization signal block is used as the information for indicating the resource of the reference signal, the resource of the reference signal can be the resource associated with the synchronization signal block. For example, the resource of the reference signal is the resource associated with the SSB. The resource associated with the SSB includes the resource associated with the CSI-RS resource set and / or SRS resource set associated with the SSB. Or, the resource associated with the SSB includes the CSI-RS resource and / or SRS resource associated with the SSB. Optionally, the network device side (such as the fifth network device) can also configure the association relationship between the SSB and the CSI-RS resource (and / or SRS resource), and / or the network device can also configure the association relationship between the SSB and the CSI-RS resource set (and / or SRS resource set).
[0249] Information A2.4, the identifier of the reference signal resource.
[0250] The identifier of the reference signal resource can include at least one of the identifier of the CSI-RS resource, the identifier of the SRS resource, and the identifier of the SSB resource. The resource of the reference signal can include the resource indicated by the identifier of the resource of the reference signal.
[0251] The identifier of the reference signal resource can be configured in the configuration information.
[0252] Information A2.5, the identifier of the resource set corresponding to the reference signal resource.
[0253] The resource set in the embodiments of the present application can be written as resource set in English. The identifier of the resource set of the reference signal resource can include 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.
[0254] Information A2.6, the identifier of the resource configuration corresponding to the reference signal resource.
[0255] In the embodiments of the present application, the English of resource configuration can be written as resource setting. The resource configuration can be associated with a resource set or a resource. When the identifier of the resource configuration is used as the information for indicating the resource of the reference signal, the resource of the reference signal can be the resource associated with the identifier of the resource configuration. The resources associated with the identifier of the resource configuration can include, for example, at least one of the identifier of the CSI-RS resource set, the identifier of the SRS resource set, the identifier of the SSB resource set, the identifier of the CSI-RS resource, the identifier of the SRS resource, and the identifier of the SSB resource.
[0256] Information A3, the information for indicating the cell that the terminal device requests to measure.
[0257] The information for indicating the cell that the terminal device requests to measure in the configuration information can indicate the cell that the terminal device requests to measure. These cells can also be understood as: the cells that the terminal device can (or is allowed, or is recommended) to request to measure.
[0258] The information for indicating the cell that the terminal device requests to measure can include, for example, the identifier of the cell.
[0259] In the embodiments of the present application, the information for indicating the cell that the terminal device requests to measure can also include other information, such as the information for indicating the trigger state. The trigger state is associated with the cell that the terminal device requests to measure. For example, the cell identifier information carried in the carrier field mentioned in the foregoing Information A2.1 can be the cell identifier information of the cell that the trigger state is associated with and the terminal device requests to measure.
[0260] In the embodiments of the present application, the information for indicating the cell that the terminal device requests to measure can also include other information, such as the information for indicating the channel state information reporting configuration. The channel state information reporting configuration is associated with the cell that the terminal device requests to measure. For example, the cell identifier information carried in the carrier field in the trigger state associated with the channel state information reporting configuration (see the foregoing Information A2.1) can be the cell identifier information of the cell that the trigger state is associated with and the terminal device requests to measure.
[0261] Information A4, the indication information of the cell for sending the measurement result information.
[0262] The indication information of the cell for sending measurement result information in the configuration information can indicate the cells for sending measurement result information. These cells can also be understood as: the cells where the terminal device can (or is allowed, or is recommended) to request to send measurement result information. These cells are used for the terminal device to send measurement result information, but these measurement result information can include the measurement result information of this cell, can also not include the measurement result information of this cell, or can include the measurement result information of other cells.
[0263] The indication information of the cell for sending measurement result information can include, for example, the identifier of the cell.
[0264] Information A5, the indication information of the resource for sending measurement result information.
[0265] The indication information of the resource for sending measurement result information included in the configuration information can indicate the resource for sending measurement result information. These resources of the reference signals can be understood as: the resources that the terminal device can (or is allowed, or is recommended) to occupy when requesting to send measurement result information (or the signaling carrying the measurement result information).
[0266] The indication information of the resource for sending measurement result information can include, for example, at least one of the identifier of the resource, the identifier of the resource set, and the identifier of the resource configuration. For example, the resource for sending measurement result information can be the resource of PUSCH and / or the resource of PUCCH. The resource for sending measurement result information can be an uplink resource, and this resource can include time domain resources and / or frequency domain resources. For another example, configure the reporting period and offset.
[0267] Information A6, the information indicating the cell to which the reference signal corresponding to the terminal device's request to send measurement result information belongs.
[0268] The information in the configuration information indicating the cell to which the reference signal corresponding to the terminal device's request to send measurement result information belongs can indicate the cell to which the reference signal corresponding to the terminal device's request to send measurement result information belongs. These cells can also be understood as: which (one or more) cells' measurement result information the terminal device can (or is allowed, or is recommended) to request to send. The measurement result information of these cells can be sent by other cells or this cell.
[0269] The information indicating the cell to which the reference signal corresponding to the terminal device's request to send measurement result information belongs can include, for example, the identifier of the cell. In the embodiments of the present application, the cell to which the reference signal corresponding to the measurement result information belongs can also be understood as: the measurement result information is measured based on the reference signal of this cell.
[0270] In a possible implementation, the cell requested by the terminal device for measurement (the cell indicated by Information A3) may be the same as or different from the cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs (the cell indicated by Information A6). When the cell requested by the terminal device for measurement (the cell indicated by Information A3) is the same as the cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs (the cell indicated by Information A6), Information A3 and Information A6 may be the same information or two pieces of information. In a possible implementation, when the cell requested by the terminal device for measurement (the cell indicated by Information A3) is the same as the cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs (the cell indicated by Information A6), Information A6 may be the information used to indicate the channel state information reporting configuration. Specifically, Information A6 may be the identification information of the cell carried in the carrier field (refer to the aforementioned Information A2.1) in the triggering state associated with the channel state information reporting configuration.
[0271] Information A7, which is used to indicate the characteristic information of the reference signal requested to be measured by the terminal device.
[0272] 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. These characteristics of the reference signal can also be understood as: the characteristics of the reference signal that the terminal device can (or is allowed to, or is recommended to) request to measure.
[0273] In the embodiments of the present application, the characteristics of the reference signal (Information A7) may include the spatial relationship of the reference signal (such as the following Information A7.1), whether the reference signal can be received by the terminal device simultaneously (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 and reception points (such as the following Information A7.4), etc., one or more of them. For example, if the information used to indicate the resources of the reference signal includes Information A7.2 and Information A7.3, then the characteristics of the reference signal include: whether the reference signal can be received by the terminal device simultaneously (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 match the actual needs of the terminal device.
[0274] Information A7.1, the multiple reference signals requested to be measured by the terminal device are sent using the same downlink spatial domain filter.
[0275] In a possible implementation, information A7.1 can be understood as the state in which the repetition in the channel resource information (such as the channel resource information associated with the trigger state) needs to be set to enabled (such as on). If the requirements for multiple reference signal symbol information A7.1 are sent from the network device side, the network device side can repeatedly send the reference signal using the same beam, and the terminal device can alternately use different receiving beams to receive, and then the terminal device can alternately measure the quality of different receiving beams.
[0276] The corresponding English for "Multiple reference signals are transmitted using the same downlink spatial domain filter" can be written as: Resources are transmitted with the same downlink spatial domain transmission filter.
[0277] For information A7.2, multiple reference signals requested by the terminal device to be measured can be received simultaneously by the terminal device.
[0278] Information A7.2 can also be replaced by "resources of multiple reference signals requested by the terminal device to be measured can be received simultaneously by the terminal device", and the corresponding English can be written as: resources can be received simultaneously by the UE.
[0279] For information A7.3, the spatial domain filters corresponding to multiple reference signals requested by the terminal device to be measured can be applied by the terminal device for simultaneous transmission.
[0280] For example, multiple reference signals correspond to multiple (such as two) spatial domain filters. The terminal device can simultaneously send multiple signals through the multiple spatial domain filters.
[0281] For information A7.4, the resources of the reference signals requested by the terminal device to be measured belong to the reference signal resources associated with N transmission reception points (TRPs), where N is a positive integer.
[0282] N can be, for example, one, or two, or other values.
[0283] Information A7.4 can also be replaced by: The resources of the reference signals requested by the terminal device to be measured are multiple reference signal resources respectively associated with N control resource set pool indices (the control resource set pool index can be denoted as coresetpoolindex).
[0284] The information A7.4 can also be replaced with: The resources of the reference signals requested by the terminal device for measurement are respectively the reference signal resources associated with the serving cell and the non-serving cell (a cell with a cell identifier different from that of the serving cell, such as multiple reference signal resources of additional PCI).
[0285] The information A7.4 can also be replaced with: The resources of the reference signals requested by the terminal device for measurement are respectively the reference signal resources belonging to two SRS resource sets, and the two resource sets are used for codebook or non-codebook measurement.
[0286] The information A7.4 can also be replaced with: The resources of the reference signals requested by the terminal device for measurement are respectively the reference signal resources belonging to two CSI / SSB resource sets.
[0287] The information A8 is used to indicate the information having an association relationship among any of the following: scheduling resources (such as the first resource), the cell requested by the terminal device for measurement (such as the second cell), the resources of the reference signals, the cell for sending the measurement result information, the resources for sending 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.
[0288] The information A8 can be understood as: The information used to indicate the association relationship among any of the 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 pieces of information having an association relationship to achieve the effect of saving signaling overhead. The following are several exemplary examples. Examples of the association relationship among any other two or more pieces of information can refer to these examples below and will not be elaborated.
[0289] Example 1, the configuration information includes the information indicating the association between the scheduling resources and the information indicating the resources of the reference signals (such as the identifier of the resources of the reference signals, or the trigger state). These association relationships can be represented in the form of a table or other forms.
[0290] For example, among at least one scheduling resource indicated by the configuration information, there is a first resource. The configuration information may further include information indicating the association relationship between the first resource and the resource for indicating the reference signal (such as the identifier of the resource for the reference signal, or the triggering state). The terminal device sends the first information through the first resource. The first network device receives the first information. The first network device can look up in the configuration information the information about the resource for indicating the reference signal associated with the first resource (such as the identifier of the resource for the reference signal, or the triggering state). The information about the resource for indicating the reference signal is the information about the resource for indicating the reference signal that the first network device determines that the terminal device requests to activate (or trigger, or enable) (such as the identifier of the resource for the reference signal, or the triggering state). It can also be understood that the resource for the reference signal indicated by the information about the resource for indicating the reference signal is the resource for the reference signal that the first network device determines that the terminal device requests to measure. It can be seen that in this solution, the terminal device does not have to carry the information about the resource for indicating the reference signal in the first information, thus reducing the signaling overhead.
[0291] In the embodiments of this application, the network device for receiving the first information subsequently is the first network device. The first network device and the fifth network device may be the same network device, or two devices of the same physical device. The first network device can obtain the configuration information. For example, the first network device can obtain the configuration information through signaling interaction with the fifth network device, or the first network device can obtain the configuration information without signaling interaction with the fifth network device.
[0292] Example 2, there is an association relationship between the scheduling resource further indicated by the configuration information and the information about the resource for indicating the reference signal.
[0293] Taking the information about the resource for indicating the reference signal including the triggering state as an example, the configuration information may include information indicating the association relationship between the scheduling resource and the triggering state. The association relationship between the scheduling resource and the triggering state can be indicated in an explicit manner or in an implicit manner. For the relevant solutions, refer to the foregoing solution of the configuration information indicating the association relationship between the scheduling resource and the resource for the reference signal. Similarly, it will not be elaborated here.
[0294] For example, among at least one scheduling resource indicated by configuration information, there is a first resource, and the configuration information may further include information for indicating a trigger state. In another possible implementation manner, the configuration information may further include information for indicating the association relationship between the first resource and the trigger state. The terminal device sends a first piece of information through the first resource. The first network device receives the first piece of information. The first network device may look up the trigger state associated with the first resource from the configuration information, and then the first network device may 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 piece of information, thereby reducing signaling overhead.
[0295] In the above example, the association relationship between the scheduling resource and other information is taken as an example for introduction. In practical applications, there may also be an association relationship between any other two or more items. For example, there is an association relationship between the information for indicating the resource of the reference signal (information A2) and the characteristics of the reference signal that the terminal device requests to measure (information A1). When the terminal device sends the information for indicating the resource of the reference signal, the network device can determine the characteristics of the reference signal that the terminal device requests to measure according to this information. In this solution, the terminal device does not need to send the information for indicating the characteristics of the reference signal that the terminal device requests to measure, thereby saving signaling overhead. For relevant examples of the association relationship between any of the information A1, information A2, information A3, information A4, information A5, information A6, and information A7, reference can be made to the above example and the relevant descriptions of the foregoing information A1, information A2, information A3, information A4, information A5, information A6, and information A7, which will not be elaborated here.
[0296] The association relationship between any of the information A1, information A2, information A3, information A4, information A5, information A6, and information A7 can be indicated in an explicit manner or in an implicit manner.
[0297] For example, there is an association relationship between the scheduling resource and the information for indicating the resource of the reference signal (such as the identifier of the resource of the reference signal, or the trigger state for another example).
[0298] In a possible implementation manner, 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 resource of a reference signal. There is a corresponding relationship between the one scheduling resource and the information of one or more resources for indicating a reference signal (such as the identifier of the resource of the reference signal, or the triggering state for example), and this corresponding relationship can be specified by a protocol or pre-configured or set for the terminal device. For example, the terminal device determines the information of the resource for indicating the reference signal corresponding to the scheduling resource through the sorting of at least one piece of information for indicating a scheduling resource in the configuration information (such as being sorted first), for example, the resource of the reference signal is the information sorted first in at least one piece of information for indicating a resource of the reference signal in the configuration information (such as the identifier of the resource of the reference signal, or the triggering state for example).
[0299] In another possible implementation manner, the configuration information includes information indicating an association relationship between a scheduling resource and the information of a resource for indicating a reference signal (such as the identifier of the resource of the reference signal, or the triggering state for example).
[0300] For another example, there is an association relationship between the scheduling resource and the information of the cell for which the terminal device requests measurement.
[0301] In a possible implementation manner, the configuration information includes information for indicating at least one scheduling resource and information for indicating at least one cell. The at least one cell is the cell for which the terminal device requests measurement. There is a corresponding relationship between the at least one scheduling resource and the at least one cell, and this corresponding relationship can be specified by a protocol or pre-configured or set for the terminal device. For example, one scheduling resource corresponds to one or two cells. The terminal device can determine the cell corresponding to a scheduling resource through the sorting of the scheduling resource indicated by the information for indicating at least one scheduling resource and the sorting of the cell indicated by the information for indicating the cell.
[0302] In another possible implementation manner, the configuration information includes some information that associates the scheduling resource with the cell. The cell is the cell for which the terminal device requests measurement. These association relationships can be represented in the form of a table or other forms. Subsequently, the terminal device can send information through the scheduling resource, so that the first network device determines the cell for which the terminal device requests measurement according to the scheduling resource and these association relationships, thereby saving signaling overhead.
[0303] 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 elaborated here.
[0304] Step 302, the terminal device sends the first information through the first cell.
[0305] Correspondingly, the first network device receives the first information through the first cell.
[0306] The first information is used to instruct the terminal device to request measurement of a reference signal. Or the first information is used to request sending measurement result information. Or the first information is used to request measurement of a reference signal and send measurement result information.
[0307] In a possible implementation manner, 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 instruct the terminal device to request measurement of a reference signal, the first information may include at least one of the information (information B1) for indicating the resource of the reference signal, the information (information B2) for indicating the cell (such as the second cell) for which the terminal device requests measurement, the feature (information B3) of the reference signal for which the terminal device requests measurement, and the information (information B7) for indicating that the terminal device requests to measure the reference signal. 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 the indication information (information B4) of the cell for sending the measurement result information, the indication information (information B5) of the resource for sending the measurement result information, the information (information B6) for indicating the cell to which the reference signal corresponding to the measurement result information requested to be sent by the terminal device belongs, and the information (information B8) for indicating that the terminal device requests to send the measurement result information.
[0308] The following separately introduces these several pieces of information.
[0309] Information B1, the information for indicating the resource of the reference signal.
[0310] The information for indicating the resource of the reference signal in the first information can indicate the resource of the reference signal, and this resource can be understood as the resource corresponding to the reference signal that the terminal device requests to measure through this first information. This resource may belong to the resource of the reference signal indicated by the configuration information. Or, this resource may not belong to the resource of the reference signal indicated by the configuration information. For example, the configuration information does not indicate the resource of the reference signal, or step 301 is not executed.
[0311] The information for indicating the resources of the reference signal may include one or more of the information for indicating the triggering state (see Information A2.1), the information for indicating the channel state information reporting configuration (see Information A2.2), the index information of the synchronization signal block (see Information A2.3), the identifier of the reference signal resource (see Information A2.4), the identifier of the resource set corresponding to the reference signal resource (see Information A2.5), or the identifier of the resource configuration corresponding to the reference signal resource (see Information A2.6).
[0312] When the first information includes the information for indicating the triggering state (see Information A2.1), the first information further indicates that the resources of the reference signal requested by the terminal device for measurement include: the resources associated with this triggering state (such as the resources associated with the channel resource information associated with the triggering state).
[0313] When the first information includes the information for indicating the channel state information reporting configuration (see Information A2.2), the first information further indicates that the resources of the reference signal requested by the terminal device for measurement include: the resources associated with this channel state information reporting configuration (such as the resources associated with the channel resource information associated with the triggering state associated with the channel state information reporting configuration).
[0314] When the first information includes the index information of the synchronization signal block (see Information A2.3), the first information further indicates that the resources of the reference signal requested by the terminal device for measurement include: the resources associated with this synchronization signal block (such as the CSI-RS resource set associated with the SSB, etc.).
[0315] When the first information includes the identifier of the reference signal resource (see Information A2.4), the first information further indicates that the resources of the reference signal requested by the terminal device for measurement include: the resources associated with the identifier of this reference signal resource (such as the resources associated with the channel resource information associated with the triggering state).
[0316] When the first information includes the identifier of the resource set corresponding to the reference signal resource (see Information A2.5), the first information further indicates that the resources of the reference signal requested by the terminal device for measurement include: the resources associated with the identifier of the resource set corresponding to this reference signal resource (such as the resources associated with the channel resource information associated with the triggering state).
[0317] When the first information includes the identifier of the resource configuration corresponding to the reference signal resource (see Information A2.6), the first information further indicates that the resources of the reference signal requested by the terminal device for measurement include: the resources associated with the identifier of this resource configuration (such as the resources associated with the channel resource information associated with the triggering state).
[0318] The relevant content of Information B1 is similar to the relevant content in the foregoing Information A2, which can be referred to and will not be elaborated here.
[0319] Information B2, which is information for indicating the cell (such as the second cell) for which the terminal device requests measurement.
[0320] The information in the first information for indicating the cell for which the terminal device requests measurement can indicate the cell for which the terminal device requests measurement. This cell can be understood as the cell for which the terminal device requests measurement through this first information. This cell can belong to the cells that the configuration information indicates are allowed (or recommended) for the terminal device to request measurement. Or, this cell may not belong to the cells that the configuration information indicates are allowed (or recommended) for the terminal device to request measurement. For example, the configuration information does not indicate the cells for which the terminal device requests measurement, or step 301 is not executed.
[0321] For information B2, reference can be made to the relevant description of the foregoing information A3, and details will not be elaborated here.
[0322] Information B3, which is the indication information of the cell for sending measurement result information.
[0323] The indication information of the cell for sending measurement result information in the first information can indicate the cell for sending measurement result information. This cell can be understood as the cell for which the terminal device requests to send measurement result information through this first information. This cell can belong to the cells that the configuration information indicates are allowed (or recommended) for the terminal device to request measurement. Or, this cell may not belong to the cells that the configuration information indicates are allowed (or recommended) for the terminal device to request measurement. For example, the configuration information does not indicate the cells for which the terminal device requests measurement, or step 301 is not executed.
[0324] For information B3, reference can be made to the relevant description of the foregoing information A4, and details will not be elaborated here.
[0325] Information B4, which is the indication information of the resource for sending measurement result information.
[0326] The indication information of the resource for sending measurement result information in the first information can indicate the resource occupied for sending measurement result information. This resource can be understood as the resource occupied by the signaling for which the terminal device requests to send measurement result information through this first information. This resource can belong to the resources that the configuration information indicates are for sending measurement result information. Or, this resource may not belong to the resources that the configuration information indicates are for sending measurement result information. For example, the configuration information does not indicate the resources for sending measurement result information, or step 301 is not executed.
[0327] For information B4, reference can be made to the relevant description of the foregoing information A5, and details will not be elaborated here.
[0328] Information B5, which is information for indicating the cell to which the reference signal corresponding to the measurement result information requested by the terminal device belongs.
[0329] The information in the first piece of information indicating 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. This cell can be understood as the cell corresponding to the measurement result information requested to be sent by the terminal device through this first piece of information (the measurement result information is obtained by measuring based on the reference signal of this cell). This cell can belong to the cell to which the reference signal corresponding to the measurement result information that the configuration information indicates is allowed (or recommended) for the terminal device to send. Or, this cell may not belong to the cell to which the reference signal corresponding to the measurement result information that the configuration information indicates is allowed (or recommended) for the terminal device to send. 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.
[0330] For information B5, reference can be made to the relevant description of the foregoing information A6, and details will not be repeated.
[0331] Information B6, which is used to indicate the characteristics of the reference signal requested to be measured by the terminal device.
[0332] The information in the first piece of information indicating 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. These characteristics can be understood as the characteristics of the reference signal requested to be measured by the terminal device through this first piece of information. These characteristics can belong to the characteristics of the reference signal that the configuration information indicates is allowed (or recommended) for the terminal device to measure. Or, this cell may not belong to the characteristics of the reference signal that the configuration information indicates is allowed (or recommended) for the terminal device to measure. For example, the configuration information does not indicate the characteristics of the reference signal measured by the terminal device, or step 301 is not executed.
[0333] In the embodiments of this application, the characteristics of the reference signal can include the spatial relationship of the reference signal (reference can be made to information A7.1), whether the reference signal can be received by the terminal device simultaneously (reference can be made to information A7.2), whether the spatial relationship corresponding to the reference signal can be applied by the terminal device for simultaneous transmission (reference can be made to information A7.3), and whether it belongs to a certain number (such as one or more) of transmission and reception points (reference can be made to information A7.4), etc., one or more of them. For example, the information used to indicate the characteristics of the reference signal can include whether the reference signal can be received by the terminal device simultaneously (reference can be made to information A7.2) and whether the spatial relationship corresponding to the reference signal can be applied by the terminal device for simultaneous transmission (reference can be made to information A7.3). These characteristics of the reference signal can make the reference signal sent by the network device side more matched with the actual needs of the terminal device.
[0334] In a possible implementation, a feature identifier (the feature identifier can be replaced with an identifier, index information, or number) can be set for each of information B6.1, information B6.2, information B6.3, and information B6.4. The feature for indicating the reference signal requested to be measured by the terminal device can be one or more of these feature identifiers. The first network device can pre-configure the association relationship between the feature identifier and each piece of information, and then determine the feature of the reference signal corresponding to the feature identifier according to the feature identifier carried in the first information.
[0335] In another possible implementation, the feature for indicating the reference signal requested to be measured by the terminal device can be reflected in the form of a bitmap. For example, a feature of a reference signal can correspond to a field in the first information, and a bit in this field corresponds to one of these pieces of information. If the bit is 1, it means that the reference signal requested to be measured by the terminal device satisfies the feature corresponding to this bit; if the bit is 0, it means that the reference signal requested to be measured by the terminal device does not need to satisfy the feature corresponding to this bit.
[0336] For the relevant content of information B6, refer to the relevant content in the foregoing information A7, and details are not repeated here.
[0337] Information B7, which is used to indicate the information for the terminal device to request to measure a reference signal.
[0338] The first information includes the information for indicating the terminal device to request to measure a reference signal. The first network device can determine based on this information that the first information is used to trigger the terminal device to request reference signal measurement.
[0339] Information B8, which is used to indicate the information for the terminal device to request to send measurement result information.
[0340] The first information includes the indication information of the resource for sending measurement result information. The first network device can determine based on this information that the first information is used to trigger the sending of measurement result information.
[0341] Information B7 and information B8 can be the same information or two pieces of information. If they are the same information, when the first information includes this information, the first network device can determine based on this information that the first information is used to trigger the measurement of the reference signal and trigger the sending of measurement result information.
[0342] In another possible implementation, the terminal device may determine a first resource, where the first resource belongs to the scheduled resources. 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. Thus, when the terminal device sends a first piece of information through the first resource, the first network device may determine, based on the first resource occupied by the first piece of information, the information associated with the first resource. 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 one or more of the PUCCH identifier of the first resource, the scheduling request resource identifier (the English name of the scheduling request resource identifier may be expressed as schedulingRequestResourceId), and the scheduling request identifier (the English name of the scheduling request identifier may be expressed as schedulingRequestId) 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.
[0343] For example, if the first resource is associated with the information (information B7) for indicating that the terminal device requests a measurement 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 a first piece of information through the first resource, and the first network device determines that the first resource is associated with the information (information B7) for indicating that the terminal device requests a measurement 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 piece of information indicates that the terminal device requests a measurement reference signal.
[0344] Another example is that the first resource is associated with the information for indicating the resource of the reference signal (such as the trigger state (information B1)). The terminal device sends a first piece of information through the first resource. The first network device receives the first piece of information. The first network device may search in the configuration information for the information for indicating the resource of the reference signal associated with the first resource (such as searching for the trigger state associated with the first resource). The information for indicating the resource of the reference signal (such as the trigger state) is the information for indicating the resource of the reference signal (such as the trigger state) that the first network device determines the terminal device requests to activate (or trigger, or enable). It can be seen that in this solution, the terminal device does not have to carry the information for indicating the resource of the reference signal in the first piece of information, thereby reducing the signaling overhead.
[0345] For another example, the first resource is associated with the cell requested to be measured by the terminal device. For example, the cell requested to be measured by the terminal device associated with the first resource is the second cell. This association relationship can be configured through the foregoing configuration information, and the configuration information may further include information for indicating the second cell. In another possible implementation, the configuration information may further 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. The first network device may look up, from the configuration information, the cell requested to be measured by the terminal device associated with the first resource, and finds that the cell requested to be measured by the terminal device associated with the first resource is the second cell. Then, the first network device may 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 have to carry, in the first information, the information for indicating the cell requested to be measured by the terminal device, thereby reducing signaling overhead.
[0346] 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 may refer to the foregoing examples and the relevant content in step 301, and will not be elaborated here.
[0347] 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. 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, according to information #1, the other information associated with information #1. The foregoing example is introduced by taking information #1 as the first resource. In practical applications, information #1 may also be other content. For example, information #1 may be information for indicating the resource of the 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. Relevant examples refer to the foregoing description and will not be elaborated here.
[0348] Step 303: The fourth network device sends the third information through the fourth cell.
[0349] Correspondingly, the terminal device receives the third information through the fourth cell.
[0350] In a possible implementation, the fourth network device sends the third information only after the first network device receives the first information. In the embodiments of the present application, the fourth network device and the first network device may be the same network device, or two devices of the same physical device. The fourth network device may obtain the first information. For example, the fourth network device may obtain the first information through signaling interaction with the first network device, or the fourth network device may obtain the first information without signaling interaction with the first network device.
[0351] In the embodiments of the present application, the third information sent by the fourth network device may be understood as the response information of the first information, or it may also be understood as the information configured by the network device for the terminal 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 through the fourth cell may trigger some parameters, such as trigger status, etc. These parameters may be the same as or different from the parameters requested by the first information.
[0352] There are various implementation forms for the content indicated by the third information. The following is an exemplary introduction through Embodiment C1 and Embodiment C2. In Embodiment C1, the third information is used to indicate successful reception or unsuccessful reception of the first information. In Embodiment 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. Embodiment C1 and Embodiment C2 may be executed separately or in combination. For example, the third information is used to indicate 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.
[0353] In Embodiment C1, the third information is used to indicate successful reception or unsuccessful reception of the first information.
[0354] In Embodiment C1, in a possible implementation, the third information may carry an acknowledgement (ACK) or a negative-acknowledgement (NACK). When the third information carries an ACK, the third information may indicate successful reception of the first information. When the third information carries an NACK, the third information may indicate unsuccessful reception of the first information.
[0355] 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 the cell that the terminal device requests to measure, and the ACK is carried in the third information (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 requests to measure as indicated by the first information; if the NACK is carried in the third information (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 requests to measure as indicated by the first information.
[0356] In Embodiment 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.
[0357] The content of Embodiment 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. Another example is when the first information is used to request sending 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.
[0358] 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 the reference signal, the third information may include at least one of the information for indicating the resource of the reference signal (information C2.1), the information for indicating the cell that the terminal device measures (such as the second cell) (information C2.2), the information for indicating the characteristics of the reference signal that the terminal device measures (information C2.3), and the information for indicating that the terminal device measures the reference signal (information C2.7). Another example is 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 the information for indicating the cell for the terminal device to send measurement result information (information C2.4), the information for indicating the resource for the terminal device to send measurement result information (information C2.5), the 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 the information for indicating that the terminal device sends measurement result information (information C2.8).
[0359] Information C2.1, information for indicating the resource of the reference signal.
[0360] The information included in the third information for indicating the resource of the reference signal may indicate the resource of the reference signal, and this resource can be understood as the resource occupied by the reference signal that the fourth network device recommends (or indicates, or allows) the terminal device to measure.
[0361] The information for indicating the resource of the reference signal may include one or more of the information for indicating the trigger state (see Information A2.1), the information for indicating the channel state information reporting configuration (see Information A2.2), the index information of the synchronization signal block (see Information A2.3), the identifier of the reference signal resource (see Information A2.4), the identifier of the resource set corresponding to the reference signal resource (see Information A2.5), or the identifier of the resource configuration corresponding to the reference signal resource (see Information A2.6).
[0362] 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 DCI. For example, the third information is DCI, and this DCI carries the identifier of CC#2, and this 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 the serving cell). This 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 use the DCI sent by one cell to trigger (or activate) the trigger state of another cell, thereby improving the flexibility of the solution, and the cell for transmitting the DCI can be a cell with better communication quality or unaffected, thereby improving the reception success rate of the DCI.
[0363] In another possible implementation manner, the terminal device may also receive a piece of information for indicating the trigger state. For example, the third information is DCI, and the terminal device may also receive a MAC CE before receiving the DCI. For example, the fourth network device sends this 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 field of a cell identifier, and the cell identifier carried in this field is the cell corresponding to the trigger state indicated in the DCI (such as the CSIrequest field of the DCI). Similarly, the cell to which the triggered (or activated) trigger state indicated by this MAC CE belongs (such as CC#2) may be different from or the same as the cell sending the MAC CE (or the cell sending the DCI) (such as CC#1).
[0364] In a possible implementation, when the fourth cell is different from the cell corresponding to the triggering state and / or channel state information reporting configuration, the priority of the terminal device to send measurement result information is lower than that of the measurement result information sending process associated with the triggering state information and / or channel state information reporting configuration corresponding to the fourth cell.
[0365] 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 that 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.
[0366] It can also be understood that the priority of sending the measurement result information associated with the triggering state and / or channel state information of other cells triggered (or activated, or enabled) by the fourth network device through the fourth cell is lower than that of the measurement result information associated with the triggering state and / or channel state information of the fourth cell. "The sending of the measurement result information associated with the triggering state and / or channel state information of other cells triggered (or activated, or enabled) by the fourth network device through the fourth cell" can also be replaced by: "The fourth network device triggers (or activates, or enables) across cells the sending of the measurement result information associated with the triggering state and / or channel state information", or replaced by "The fourth network device schedules across cells the reporting of the measurement result information". "The sending of the measurement result information associated with the triggering state and / or channel state information of the fourth cell triggered (or activated, or enabled) by the fourth network device through the fourth cell" can also be replaced by: "The fourth network device triggers (or activates, or enables) within the same cell the sending of the measurement result information associated with the triggering state and / or channel state information", or replaced by "The fourth network device schedules within the same cell the reporting of the measurement result information". In this way, the sending of the measurement result information associated with cross-cell scheduling will not cause significant interference to the sending of the measurement result information associated with in-cell scheduling.
[0367] For example, when the reporting of the measurement result information scheduled by the fourth network device across cells and the reporting of the measurement result information scheduled by the fourth network device within the same cell overlap on at least one OFDM symbol in the time domain of the same subcarrier, then the priority of the reporting of the measurement result information scheduled across cells is lower than that of the reporting of the measurement result information scheduled within the same cell, and the terminal device can multiplex or discard (i.e., not report) the measurement result information scheduled across cells according to this priority rule. In a possible implementation, there are the following priority rules for the reporting of the measurement result information:
[0368] Pri iCSI (z,y,k,c,s)=3·N cells·M s ·z + 2·N cells ·M s ·y + N cells ·M s ·k + M s ·c + s
[0369] Among them, z = 0 indicates the reporting of cross - cell scheduling measurement result information by the network device (such as the fourth network device); z = 1 indicates the reporting of in - cell scheduling measurement result information by the network device (such as the fourth network device).
[0370] y = 0 indicates the aperiodic CSI report carried by PUSCH, y = 1 indicates the semi - persistent CSI report carried by PUSCH, y = 2 indicates the semi - persistent CSI report carried by PUCCH, and y = 3 indicates the periodic CSI report carried by PUCCH.
[0371] k = 0 indicates the CSI report carrying L1 - RSRP or L1 - SINR, and k = 1 indicates the CSI report not carrying L1 - RSRP or L1 - SINR.
[0372] c represents the serving cell index.
[0373] N cells represents the maximum number of serving cells configured by a higher - layer parameter (this higher - layer parameter can be maxNrofServingCells).
[0374] s is the reporting configuration identifier (the reporting configuration identifier can be denoted as reportConfigID).
[0375] M s represents the maximum number of CSI reporting configurations configured by a higher - layer parameter (this higher - layer parameter can be maxNrofCSI - ReportConfigurations).
[0376] Pri iCSI (z, y, k, c, s) represents the priority, where Pri iCSI (z, y, k, c, s) The smaller the value, the higher the priority can be.
[0377] In an embodiment of the present application, the fourth network device sending the third information through the fourth cell can be used to schedule the triggering status and / or channel status information reporting configuration of the fourth cell or a non-fourth cell. Since the third information is sent by the fourth network device based on the first information, this process also belongs to the reporting process of measurement result information triggered by the terminal device. In another possible implementation manner, the solution provided in the embodiment of the present application can also be applied to the reporting process of measurement result information triggered by the network device. In this solution, it is not necessary for the terminal device to first trigger or activate the reporting of measurement result information. Instead, the network device side first triggers or activates the reporting of measurement result information. In this solution, the cell sent by the network device for triggering the reporting of measurement result information may be different (or the same) from the cell associated with the triggering status and / or channel status information reporting configuration actually activated by the network device through this information. For example, the network device can send the measurement result information associated with the triggering status of CC#2 (or the channel status information reporting configuration of CC#2) triggered by the DCI sent on CC#1. This DCI is not the information sent based on the first information of the terminal device, but is sent independently by the network device.
[0378] In a possible implementation manner, when the fourth cell is different from the cell corresponding to the triggering status (or channel status information reporting configuration), the information for indicating the triggering status (or channel status information reporting configuration) may include the identifier of the cell corresponding to the triggering status (or channel status information reporting configuration), so that the terminal device can determine that the third information does not trigger (or activate) the triggering status (or channel status information reporting configuration) corresponding to the fourth cell.
[0379] In another possible implementation manner, when the fourth cell is different from the cell corresponding to the triggering status (or channel status information reporting configuration), the information for indicating the triggering status (or channel status information reporting configuration) may not include the identifier of the cell corresponding to the triggering status (or channel status information reporting configuration), and the terminal device can determine that the third information triggers (or activates) the triggering status (or channel status information reporting configuration) corresponding to the fourth cell.

[0381] Information C2.2, which is used to indicate the information of the cell measured by the terminal device.

The cells indicated by the third information and the first information respectively can be the same or different. The terminal device may or may not use the cell indicated by the third information for measurement. The cell indicated by the third information for measurement by the terminal device may belong to the cells indicated by the configuration information for measurement by the terminal device.

[0392] For information C2.5, reference may be made to the relevant descriptions of the foregoing information A6 and information B5, which will not be elaborated herein.

[0399] The third information includes information used to indicate the information of the measurement result sent by the terminal device, and the terminal device can determine based on this information that the third information is at least used to trigger the sending of the measurement result information.
[0400] Information C2.7 and information C2.8 can 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 at least based on this information that the third information is used to trigger the measurement of the reference signal and the sending of the measurement result information.
[0401] In the embodiments of the present application, the first information sent by the terminal device can indicate some information, such as one or more of the foregoing information B1, information B2, information B3, information B4, information B5, information B6, information B7, and information B8. The fourth network device can, in response to the request of the terminal device, for example, agree to the terminal device to use the information requested by the terminal device. Or, the fourth network device can also disagree with the terminal device to use the information requested by the terminal device.
[0402] The fourth network device may also reconfigure some information for the terminal device through the third information. The types of information configured by the third information (which may also be referred to as parameter items) may include some or all of the information types (which may also be referred to as parameter items) indicated by the first information. For the same information type, the specific value of this 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 this information indicated by the first information. For example, the first information indicates that the terminal device requests to send measurement result information using Resource #1. 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 using Resource #2. Resource #2 can be understood as the specific value of Information B4 indicated by the third information, and Resource #2 may be the same as or different from Resource #1. If the terminal device receives this third information, it may (or may not) use Resource #2 to send measurement result information.
[0403] In another possible implementation, after the fourth network device receives the first information, it may configure some information for the terminal device through the third information, and these information may not be indicated by the first information. For example, the first information does not indicate the indication information (Information B3) of the cell for sending measurement result information. The fourth network device may indicate this information to the terminal device through the third information.
[0404] In the embodiments of the present application, the information indicated by the third information is the information recommended by the fourth network device. The terminal device may use the information indicated by the third information or may not use it. The information indicated by the third information may belong to the information indicated by the configuration information or may not belong to the information indicated by the configuration information.
[0405] In a possible implementation, the terminal device may start measuring the reference signal and / or sending measurement result information after a period of time (such as a period of time specified by the protocol, and this period of time may be a specified number of time slots or a specified number of symbols, etc.) after receiving the third information. The third information may indicate that the first information has been successfully received, or indicate acceptance of the content indicated by the first information, or indicate one or more of Information C2.1, Information C2.2, Information C2.3, Information C2.4, Information C2.5, Information C2.6.
[0406] Step 304, the second network device sends at least one reference signal through the second cell.
[0407] Correspondingly, the terminal device receives at least one reference signal through the second cell.
[0408] In a possible implementation, the second network device sends reference signals frequently, such as sending reference signals periodically, etc., and the terminal device may measure these reference signals.
[0409] In yet another possible implementation, the second network device sends a reference signal after the first network device receives the first information. This reference signal can be more matched with the reference signal that the terminal device actually needs to measure. For example, this reference signal can have the characteristics of the reference signal requested by the terminal device to measure. In the embodiments of the present application, the second network device and the first network device can be the same network device, or two devices of the same physical device. The second network device can obtain the first information. For example, the second network device can obtain the first information through signaling interaction with the first network device, or the second network device can obtain the first information without signaling interaction with the first network device.
[0410] For the content of step 304, reference can be made to the content of the foregoing step 202, which will not be elaborated herein.
[0411] Step 305, the terminal device measures at least one reference signal to obtain at least one measurement result information.
[0412] For the content of step 305, reference can be made to the content of the foregoing step 203, which will not be elaborated herein.
[0413] Step 306, the terminal device sends the second information through the third cell.
[0414] Correspondingly, the third network device receives the second information through the third cell.
[0415] The second information includes at least one measurement result information.
[0416] For the content of step 306, reference can be made to the content of the foregoing step 212, which will not be elaborated herein.
[0417] The above Figure 3 Some steps in the provided solutions can be not executed. For example, step 301 can be not executed, and for another example, step 303 can be not executed. For another example, step 306 can be not 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, if steps 304 and 305 are not executed, in this case, the measurement result information included in the second information in step 306 can be the measurement result information measured by the terminal device before, such as the measurement result information obtained by the terminal device measuring the reference signal periodically.
[0418] The information (such as the first information and / or the second information) sent by the terminal device in the embodiments of the present application can be sent through uplink control information (UCI) and MAC CE, and these information can be carried on the physical uplink control channel (PUCCH) and / or the physical uplink shared channel (PUSCH). The information received by the terminal device (such as configuration information and / or the third information) can be sent through DCI and MAC CE, and these information can be carried on the physical downlink control channel (PUCCH) and / or the physical downlink shared channel (PUSCH).
