Description

[Technical Field]

[0001] This application claims priority to Chinese Patent Application No. 202210945494.5, filed with the State Intellectual Property Office of China on August 8, 2022, entitled "Measurement Method, Scheduling Method and Apparatus," which is incorporated herein by reference in its entirety.

[0002] TECHNICAL FIELD Embodiments of the present application relate to the field of communications, and in particular to a measurement method, a scheduling method and an apparatus. [Background technology]

[0003] In wireless communication systems, received signal strength indicator (RSSI) and channel occupancy (CO) measurements are defined. RSSI represents the average power value of each orthogonal frequency division multiplexing (OFDM) symbol in the measurement bandwidth. CO measurements are used to determine the percentage of OFDM symbols whose power exceeds a threshold in the measurement bandwidth.

[0004] In the low frequency band, if the RSSI / CO measurement bandwidth is within the active bandwidth part (BWP) of the terminal device's serving cell, the terminal device may perform RSSI / CO measurement and downlink reception simultaneously.

[0005] However, in high frequency bands, due to the high frequency, downlink reception and RSSI / CO measurement by the terminal device needs to be performed in a specific beam direction, in which case some implementations of RSSI / CO measurement in low frequency bands may no longer be applicable. Summary of the Invention

[0006] The present application provides a measurement method, a scheduling method, and an apparatus, which can reduce the impact of beam switching on measurement results, thereby reducing measurement errors.

[0007] According to a first aspect, there is provided a measurement method. The method can be executed by a first terminal device and can be executed by a component of the first terminal device, such as a processor, chip, or chip system of the first terminal device, or can be implemented by a logic module or software capable of implementing all or part of the functions of the first terminal device. The method includes determining a first time-domain symbol group and determining measurement results of RSSI measurements and / or channel occupancy CO measurements in the first time-domain symbol group. The first time-domain symbol group includes time-domain symbols in an RMTC window other than a second time-domain symbol group. The second time-domain symbol group includes the first N time-domain symbols and / or the last M time-domain symbols in the RMTC window, where N and M are positive integers.

[0008] Based on this solution, when determining the measurement result of the RSSI measurement and / or the measurement result of the CO measurement, the terminal device excludes the first N time domain symbols and / or the last M time domain symbols in the RMTC window. When performing beam switching on the first N time domain symbols and / or the last M time domain symbols, the first N time domain symbols and / or the last M time domain symbols are not involved in the calculation of the measurement result, thereby reducing the impact of beam switching on the measurement result and thereby reducing the measurement error.

[0009] In a possible design, when the first subcarrier spacing is greater than or equal to a first threshold, the second time domain symbol group includes the first N time domain symbols and / or the last M time domain symbols in the RMTC window, the first subcarrier spacing is a subcarrier spacing of an active bandwidth portion BWP of a first carrier, and the first carrier is a carrier in which a measurement bandwidth for RSSI measurement or CO measurement is located; or the first subcarrier spacing is a subcarrier spacing for RSSI measurement or CO measurement.

[0010] Based on a possible design, when the subcarrier spacing is large, the length of the time domain symbol is small. In this case, the time length occupied by beam switching on the time domain symbol cannot be ignored. The time domain symbols in the RMTC window where beam switching may occur are excluded, so that the first N time domain symbols and / or the last M time domain symbols are not involved in the calculation of the measurement result, which can reduce the impact of beam switching on the measurement result and thereby reduce the measurement error.

[0011] In a possible design, if the RSSI measurement resource and the first downlink signal are not quasi-co-located QCL, the second time domain symbol group includes the first N time domain symbols in the RMTC window, where the first downlink signal is a downlink signal on the first time domain symbol before the RMTC window, or the first downlink signal is a downlink signal before the RMTC window and closest to the RMTC window; the RSSI measurement resource is used for RSSI measurement or CO measurement; and / or if the RSSI measurement resource and the second downlink signal are not QCL, the second time domain symbol group includes the last M time domain symbols in the RMTC window, where the second downlink signal is a downlink signal on the first time domain symbol after the RMTC window, or the second downlink signal is a downlink signal after the RMTC window and closest to the RMTC window.

[0012] According to a possible design, when the RSSI measurement resource and the first downlink signal are not QCL, the first terminal device needs to perform beam switching to perform RSSI / CO measurement after receiving the first downlink signal. In this case, if beam switching is performed on the first N time-domain symbols in the RMTC window, the measurement results for the first N time-domain symbols will be affected. In this case, the first N time-domain symbols in the RMTC window can be excluded from the first time-domain symbol group to reduce the impact of beam switching on the measurement results and reduce measurement errors.

[0013] When the RSSI measurement resource and the second downlink signal are not QCL, after RSSI / CO measurement, the first terminal device needs to perform beam switching to receive the second downlink signal. In this case, if beam switching is performed on the last M time-domain symbols in the RMTC window, the measurement results for the last M time-domain symbols will be affected. In this case, the last M time-domain symbols in the RMTC window can be excluded from the first time-domain symbol group to reduce the impact of beam switching on the measurement results and reduce measurement errors.

[0014] In a possible design, the method further comprises transmitting capability information to the network device, wherein the capability information indicates whether the first terminal device supports simultaneously performing RSSI / CO measurement and downlink reception when the RSSI measurement resource and the downlink signal are QCL.

[0015] According to a second aspect, there is provided a scheduling method. The method may be executed by a network device, may be executed by a component of the network device, for example, a processor, chip, or chip system of the network device, or may be implemented by a logic module or software capable of implementing all or part of the functions of the network device. The method includes: determining an RMTC configuration for a first terminal device, where the RMTC configuration is used for RSSI measurements and / or channel occupancy CO measurements; and determining transmission resources available for downlink signals to the first terminal device according to a scheduling rule, where the scheduling rule includes prohibiting the network device from transmitting downlink signals to the first terminal device on a second time-domain symbol group on a first carrier. The first carrier is a carrier on which a measurement bandwidth for RSSI measurements and / or a measurement bandwidth for CO measurements is located; and the second time-domain symbol group includes the first N time-domain symbols and / or the last M time-domain symbols in an RMTC window of the first terminal device, where N and M are positive integers.

[0016] In a scenario in which the first terminal device may perform beam switching on the second time domain symbol group, when the network device transmits a downlink signal to the first terminal device on the second time domain symbol group on the first carrier, the first terminal device may be unable to perform downlink reception, resulting in a transmission failure and wasting resources. Based on this solution, the network device is prohibited from transmitting a downlink signal to the first terminal device on the second time domain symbol group on the first carrier. Therefore, the network device may not transmit a downlink signal to the first terminal device on the second time domain symbol group on the first carrier, thereby reducing resource waste.

[0017] In a possible design, when the first subcarrier spacing is greater than or equal to a first threshold, the second time domain symbol group includes the first N time domain symbols and / or the last M time domain symbols in the RMTC window, the first subcarrier spacing being a subcarrier spacing of an active bandwidth portion BWP of the first carrier, or the first subcarrier spacing being a subcarrier spacing of an RSSI measurement or a CO measurement.

[0018] In a possible design, if the RSSI measurement resource and the first downlink signal are not quasi-co-located QCL, the second time domain symbol group includes the first N time domain symbols in the RMTC window, where the first downlink signal is a downlink signal on the first time domain symbol before the RMTC window, or the first downlink signal is a downlink signal before the RMTC window and closest to the RMTC window; the RSSI measurement resource is used for RSSI measurement or CO measurement; and / or if the RSSI measurement resource and the second downlink signal are not QCL, the second time domain symbol group includes the last M time domain symbols in the RMTC window, where the second downlink signal is a downlink signal on the first time domain symbol after the RMTC window, or the second downlink signal is a downlink signal after the RMTC window and closest to the RMTC window.

[0019] In one possible design, the scheduling rule further includes prohibiting the network device from transmitting a downlink signal that is not an RSSI measurement resource and a QCL to the first terminal device on a first time domain symbol group on the first carrier, the first time domain symbol group including time domain symbols other than the second time domain symbol group in the RMTC window.

[0020] In one possible design, the scheduling rule further includes allowing the network device to transmit a downlink signal, which is the RSSI measurement resource and the QCL, to the first terminal device on a first time domain symbol group on a first carrier, the first time domain symbol group including time domain symbols other than the second time domain symbol group in the RMTC window.

[0021] Based on two possible designs, the network device can transmit a downlink signal, which is an RSSI measurement resource and a QCL, to the first terminal device on a first time-domain symbol group on the first carrier. When the downlink signal and the RSSI measurement resource are QCL, the first terminal device can perform RSSI / CO measurement and downlink reception using the same beam, i.e., the first terminal device can perform downlink reception while performing RSSI / CO measurement, so that the resource is fully utilized, thereby improving resource utilization and network throughput.

[0022] In a possible design, the scheduling rule further includes prohibiting the network device from transmitting downlink signals to the first terminal device on a third time domain symbol group on a second carrier, where the second carrier and the first carrier are in the same frequency band and the time domain symbols in the third time domain symbol group partially or completely overlap with the time domain symbols in the second time domain symbol group.

[0023] According to a possible design, the network device is prohibited from transmitting a downlink signal to the first terminal device on the third time domain symbol group on the second carrier. Thus, the network device may not transmit a downlink signal to the first terminal device on the third time domain symbol group on the second carrier, thereby reducing resource waste.

[0024] In a possible design, the scheduling rule further includes prohibiting the network device from transmitting a downlink signal that is not an RSSI measurement resource and a QCL to the first terminal device on a fourth time domain symbol group on the second carrier, the time domain location of the fourth time domain symbol group including a time domain location in the time domain position of the RMTC window other than the time domain location of the third time domain symbol group.

[0025] In one possible design, the scheduling rule further includes allowing the network device to transmit a downlink signal, the RSSI measurement resource and QCL, to the first terminal device on a fourth time domain symbol group on the second carrier, the time domain location of the fourth time domain symbol group including a time domain location in the time domain position of the RMTC window other than the time domain location of the third time domain symbol group.

[0026] Based on two possible designs, the network device can transmit a downlink signal, which is an RSSI measurement resource and a QCL, to the first terminal device on the fourth time-domain symbol group on the second carrier. When the downlink signal and the RSSI measurement resource are QCL, the first terminal device can perform RSSI / CO measurement and downlink reception using the same beam, that is, the first terminal device can perform downlink reception while performing RSSI / CO measurement, so that the resource is fully utilized, thereby improving resource utilization and network throughput.

[0027] In a possible design, the method further comprises receiving capability information from the first terminal device, the capability information indicating whether the first terminal device supports simultaneously performing RSSI / CO measurement and downlink reception when the RSSI measurement resource and the downlink signal are QCL.

[0028] According to a third aspect, a scheduling method is provided. The method may be executed by a network device, may be executed by a component of the network device, for example, a processor, chip, or chip system of the network device, or may be implemented by a logic module or software capable of implementing all or part of the functions of the network device. The method includes: determining an RMTC configuration for a first terminal device, where the RMTC configuration is used for RSSI measurements and / or channel occupancy CO measurements; and determining transmission resources available for downlink signals to the first terminal device according to a scheduling rule, where the scheduling rule includes prohibiting the network device from transmitting RSSI measurement resources and downlink signals that are not QCL to the first terminal device on a first time domain symbol group on a first carrier. The first time domain symbol group includes time domain symbols in the RMTC window other than those in the second time domain symbol group. The second time domain symbol group includes the first N time domain symbols and / or the last M time domain symbols in the RMTC window of the first terminal device, where N and M are positive integers.

[0029] Based on this design, the network device may transmit a downlink signal, which is an RSSI measurement resource and a QCL, to the first terminal device on a first time-domain symbol group on the first carrier. When the downlink signal and the RSSI measurement resource are QCL, the first terminal device may perform RSSI / CO measurement and downlink reception using the same beam, i.e., the first terminal device may perform downlink reception while performing RSSI / CO measurement, so that the resource is fully utilized, thereby improving resource utilization and network throughput.

[0030] According to a fourth aspect, there is provided a scheduling method. The method may be executed by a network device, may be executed by a component of the network device, for example, a processor, chip, or chip system of the network device, or may be implemented by a logic module or software capable of implementing all or part of the functions of the network device. The method comprises: determining an RMTC configuration for a first terminal device, where the RMTC configuration is used for RSSI measurements and / or channel occupancy CO measurements; and determining transmission resources available for downlink signals to the first terminal device according to a scheduling rule, where the scheduling rule includes prohibiting the network device from transmitting downlink signals to the first terminal device on a fifth time domain symbol group on a first carrier. The first carrier is a carrier on which a measurement bandwidth for RSSI measurements and / or a measurement bandwidth for CO measurements is located; and the fifth time domain symbol group includes X time domain symbols before an RMTC window of the first terminal device and / or Y time domain symbols after the RMTC window, where X and Y are positive integers.

[0031] When beam switching is performed on X time domain symbols before the RMTC window, the first terminal device may be unable to perform downlink reception on the X time domain symbols. In this case, if the network device still transmits downlink signals to the first terminal device on the X time domain symbols on the first carrier, a transmission failure will occur because the first terminal device cannot perform downlink reception, resulting in resource waste. Based on this solution, the network device is prohibited from transmitting downlink signals to the first terminal device on the X time domain symbols on the first carrier, thereby reducing resource waste caused by the network device transmitting downlink signals but the first terminal device being unable to receive the downlink signals.

[0032] Similarly, when beam switching is performed on Y time domain symbols after the RMTC window, based on this solution, the network device is prohibited from transmitting downlink signals to the first terminal device on the Y time domain symbols on the first carrier, thereby reducing the waste of resources caused by the network device transmitting downlink signals but the first terminal device being unable to receive the downlink signals.

[0033] In a possible design, when the first subcarrier spacing is greater than or equal to a first threshold, the fifth time domain symbol group includes X time domain symbols before the RMTC window and / or Y time domain symbols after the RMTC window, and the first subcarrier spacing is a subcarrier spacing of an active bandwidth portion BWP of the first carrier, or the first subcarrier spacing is a subcarrier spacing of an RSSI measurement or a CO measurement.

[0034] In a possible design, if the RSSI measurement resource and the third downlink signal are not quasi-co-located QCL, the fifth time domain symbol group includes X time domain symbols before the RMTC window, where the third downlink signal is a downlink signal on the X time domain symbols, or the third downlink signal is a downlink signal prior to and nearest to the X time domain symbols; the RSSI measurement resource is used for RSSI measurement or CO measurement; if the RSSI measurement resource and the fourth downlink signal are not QCL, the fifth time domain symbol group includes Y time domain symbols after the RMTC window, where the fourth downlink signal is a downlink signal on the Y time domain symbols, or the fourth downlink signal is a downlink signal after and nearest to the Y time domain symbols.

[0035] In a possible design, the scheduling rule further includes: prohibiting the network device from transmitting RSSI measurement resources and downlink signals that are not QCL to the first terminal device in an RMTC window on the first carrier.

[0036] In a possible design, the scheduling rule further includes: allowing the network device to transmit a downlink signal, which is an RSSI measurement resource and a QCL, to the first terminal device in an RMTC window on the first carrier.

[0037] Based on two possible designs, the network device can transmit a downlink signal, which is an RSSI measurement resource and a QCL, to the first terminal device in the RMTC window on the first carrier. When the downlink signal and the RSSI measurement resource are QCL, the first terminal device can perform RSSI / CO measurement and downlink reception using the same beam, that is, the first terminal device can perform downlink reception while performing RSSI / CO measurement, so that the resource is fully utilized, thereby improving resource utilization and network throughput.

[0038] In one possible design, the scheduling rule further includes prohibiting the network device from transmitting downlink signals to the first terminal device on a sixth time domain symbol group on a second carrier, where the second carrier and the first carrier are in the same frequency band, and the time domain symbols in the sixth time domain symbol group partially or completely overlap with the time domain symbols in the fifth time domain symbol group.

[0039] In a possible design, the scheduling rule further includes prohibiting the network device from transmitting a downlink signal that is not an RSSI measurement resource and a QCL to the first terminal device on a seventh time domain symbol group on the second carrier, the time domain location of the seventh time domain symbol group including a time domain location in the time domain position of the RMTC window other than the time domain location of the sixth time domain symbol group.

[0040] In one possible design, the scheduling rule further includes allowing the network device to transmit a downlink signal, the RSSI measurement resource and QCL, to the first terminal device on a seventh time domain symbol group on the second carrier, the time domain location of the seventh time domain symbol group including a time domain location in the time domain position of the RMTC window other than the time domain location of the sixth time domain symbol group.

[0041] In a possible design, the method further comprises receiving capability information from the first terminal device, the capability information indicating whether the first terminal device supports simultaneously performing RSSI / CO measurement and downlink reception when the RSSI measurement resource and the downlink signal are QCL.

[0042] According to a fifth aspect, there is provided a scheduling method. The method may be executed by a network device, may be executed by a component of the network device, for example, a processor, chip, or chip system of the network device, or may be implemented by a logic module or software capable of implementing all or part of the functions of the network device. The method comprises: determining an RMTC configuration for a first terminal device, where the RMTC configuration is used for RSSI measurement and / or channel occupancy CO measurement; and determining transmission resources available for downlink signals to the first terminal device according to a scheduling rule, where the scheduling rule includes prohibiting the network device from transmitting RSSI measurement resources and downlink signals that are not QCL to the first terminal device in an RMTC window on a first carrier. The first carrier is a carrier on which the measurement bandwidth for RSSI measurement and / or the measurement bandwidth for CO measurement are located.

[0043] Based on this design, the network device may transmit an RSSI measurement resource and a downlink signal, which is a QCL, to the first terminal device in the RMTC window on the first carrier. When the downlink signal and the RSSI measurement resource are QCL, the first terminal device may perform RSSI / CO measurement and downlink reception using the same beam, i.e., the first terminal device may perform downlink reception while performing RSSI / CO measurement, so that the resource is fully utilized, thereby improving resource utilization and network throughput.

[0044] According to a sixth aspect, there is provided a communication method. The method can be executed by a first terminal device and can be executed by a component of the first terminal device, such as a processor, chip, or chip system of the first terminal device, or can be implemented by a logic module or software capable of implementing all or part of the functions of the first terminal device. The method comprises: determining capability information; and transmitting the capability information to a network device. The capability information indicates whether the first terminal device supports simultaneously performing RSSI / channel occupancy CO measurements and downlink reception when the received signal strength indicator (RSSI) measurement resource and the downlink signal are quasi-colocated QCL.

[0045] Based on this solution, the first terminal device reports the capability information of the first terminal device to the network device, so that the network device performs scheduling more accurately based on the capability information and improves scheduling efficiency.

[0046] In a possible design, the capability information indicates that the first terminal device does not support simultaneously performing RSSI / CO measurements and downlink reception when the RSSI measurement resource and the downlink signal are QCL, and the method further comprises: when the network device configures the first terminal device to receive the downlink signal while performing RSSI / CO measurements on the RSSI measurement resource, the first terminal device performs RSSI / CO measurements and does not receive the downlink signal.

[0047] According to a seventh aspect, there is provided a communication method. The method may be executed by a network device, and may be executed by a component of the network device, for example, a processor, chip, or chip system of the network device, or may be implemented by a logic module or software capable of implementing all or part of the functions of the network device. The method includes: receiving capability information from a first terminal device; and determining, based on the capability information, transmission resources available for downlink signals to the first terminal device. The capability information indicates whether the first terminal device supports simultaneously performing RSSI / channel occupancy CO measurements and downlink reception when the received signal strength indicator (RSSI) measurement resource and the downlink signal are quasi-colocated QCL. For technical effects provided by the seventh aspect, please refer to the technical effects provided by the sixth aspect. Details will not be described again here.

[0048] In a possible design, when the RSSI measurement resource and the downlink signal are QCL, if the capability information indicates that the first terminal device does not support simultaneously performing RSSI / CO measurement and downlink reception, the transmission resources available for the downlink signal to the first terminal device do not include the RMTC window on the first carrier.

[0049] According to an eighth aspect, there is provided a measurement method. The method can be executed by a first terminal device, and can be executed by a component of the first terminal device, such as a processor, chip, or chip system of the first terminal device, or can be implemented by a logic module or software capable of implementing all or part of the functions of the first terminal device. The method includes: determining an eighth time-domain symbol group; and determining measurement results of received signal strength indicator (RSSI) measurements and / or channel occupancy CO measurements on the eighth time-domain symbol group.

[0050] If the length of the RSSI measurement timing configuration RMTC window is greater than or equal to the second threshold, the eighth time domain symbol group includes time domain symbols other than the ninth time domain symbol group in the RMTC window, and the ninth time domain symbol group includes the first N time domain symbols and / or the last M time domain symbols in the RMTC window, where N and M are positive integers. Alternatively, if the length of the RMTC window is less than the second threshold, the eighth time domain symbol group includes all time domain symbols in the RMTC window.

[0051] Based on this solution, the terminal device can choose to perform beam switching in or outside the RMTC window based on the length of the RMTC window. When the length of the RMTC window is long, beam switching is performed in the RMTC window, so that downlink transmissions can be performed before and after the RMTC window, improving resource utilization and network throughput. When the length of the RMTC window is short, beam switching is performed outside the RMTC window, reducing the impact of beam switching on RSSI / CO measurements and improving the accuracy of the measurement results.

[0052] In a possible design, the length of the RMTC window is the total number of time-domain symbols in the RMTC window, or the length of the RMTC window is the length of time occupied by the RMTC window.

[0053] According to a ninth aspect, there is provided a scheduling method. The method may be executed by a network device, may be executed by a component of the network device, for example, a processor, chip, or chip system of the network device, or may be implemented by a logic module or software capable of implementing all or part of the functions of the network device. The method comprises: determining an RMTC configuration for a first terminal device, where the RMTC configuration is used for RSSI measurements and / or channel occupancy CO measurements; and determining transmission resources available for downlink signals to the first terminal device according to a scheduling rule. The scheduling rule includes: prohibiting the network device from transmitting downlink signals to the first terminal device on a tenth time domain symbol group on a first carrier.

[0054] If the length of the RMTC window is greater than or equal to the second threshold, the tenth time-domain symbol group includes the first N time-domain symbols and / or the last M time-domain symbols in the RMTC window, where N and M are positive integers. Alternatively, if the length of the RMTC window is less than the second threshold, the tenth time-domain symbol group includes X time-domain symbols before the RMTC window and / or Y time-domain symbols after the RMTC window, where X and Y are positive integers.

[0055] According to this solution, the network device determines transmission resources on which it is forbidden to transmit downlink signals to the first terminal device based on the length of the RMTC window, and in a scenario where beam switching is performed on these transmission resources, the network device does not transmit downlink signals to the first terminal device on these transmission resources, thereby reducing resource waste.

[0056] In a possible design, the length of the RMTC window is the total number of time-domain symbols in the RMTC window, or the length of the RMTC window is the length of time occupied by the RMTC window.

[0057] According to a tenth aspect, a communication device is provided, which implements the above-mentioned method.

The following implementations of this application are not intended to limit the protection scope of this application.

[0079] In wireless communication systems, different networks may use the same unlicensed frequency band. Therefore, when operating on the unlicensed spectrum, terminal devices may be interfered with, affecting data transmission and throughput. To reduce interference on the unlicensed spectrum, received signal strength indicator (RSSI) measurement and channel occupancy (CO) measurement are introduced.

[0080] In the low-frequency unlicensed frequency band in frequency range 1 (FR1), a terminal device can perform reception by using an omnidirectional antenna and does not need to align a beam in a specific direction. Therefore, in the low-frequency unlicensed frequency band, if the RSSI / CO measurement bandwidth is within the active bandwidth part (BWP) of the terminal device's serving cell, the terminal device can perform RSSI / CO measurement and downlink reception simultaneously.

[0081] In the high-frequency unlicensed frequency band in frequency range 2 (FR2), narrow beams need to be used to increase coverage due to the high frequency. In this case, the terminal device needs to perform downlink reception in the beam direction by using beamforming technology. In addition, the terminal device needs to perform RSSI / CO measurements in the beam direction.

[0082] The network device may send an RSSI measurement timing configuration (RMTC) to the terminal device to configure the terminal device to perform RSSI / CO measurements. For example, the RMTC configuration may include at least one of the following:

[0083] RMTC Periodicity: Indicates the period of RSSI / CO measurement.

[0084] RMTC Subframe Offset (RMTC-SubFrameOffset): Indicates the start time domain position of the RMTC window. The RMTC window can be understood as a time domain resource for RSSI / CO measurements.

[0085] MeasDurationSymbols: Indicates the duration of time occupied by the RMTC window.

[0086] RMTC Frequency (rmtc-Frequency): Indicates the center frequency of the measurement bandwidth of the RSSI / CO measurement. For example, the indication may be an absolute frequency, such as an absolute radio frequency channel number (ARFCN). The carrier on which the RSSI / CO measurement is performed may be identified based on the absolute frequency.

[0087] Reference subcarrier spacing (ref-SCS-CP): Indicates the reference subcarrier spacing (SCS) and cyclic prefix (CP) used for RSSI measurement.

[0088] For the high frequency band, in addition to at least one of the above, the RMTC configuration may further include at least one of the following:

[0089] RMTC Bandwidth (rmtc-Bandwidth): Indicates the measurement bandwidth for RSSI / CO measurements.

[0090] Transmission configuration indicator state information (tci-StateInfo): indicates the TCI state for RSSI measurement, where the TCI state indicates the downlink (DL) reference signal (RS). The RSSI measurement resource and the downlink reference signal (corresponding reference signal resource) are quasi-colocated (QCL-ed). The RSSI measurement resource is used for RSSI measurement / CO measurement. For example, the RSSI measurement resource may be a time-frequency resource.

[0091] Generally, "QCL-ed" in this application refers to a type D QCL (i.e., a type D QCL). Of course, in various operational variations provided in the embodiments of this application, "QCL-ed" may alternatively refer to a QCL of another type (e.g., type A, type B, or type C). This is not limiting here.

[0092] The fact that multiple resources are QCLs may indicate that the multiple resources have one or more identical or similar communication characteristics. The same or similar communication configuration may be used for multiple resources that are QCLs. For example, reception may be performed on multiple resources by using the same beam. In this case, the TCI status information may be considered to indicate the beam to be used for RSSI / CO measurements.

[0093] A beam may be represented in a protocol as a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, QCL information, QCL assumption, QCL indication, or the like. A beam may be indicated by using a transmission configuration indication (TCI) state (TCI-state) parameter or by using a spatial relation parameter. Therefore, in this application, a beam may be replaced with a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, QCL information, QCL assumption, QCL indication, TCI state, a spatial relation, or the like. The above terms are also equivalent to each other. In this application, a beam may alternatively be replaced with another term representing a beam. This is not a limitation in this application.

[0094] When the RMTC configuration does not include TCI status information, the terminal device may assume that the RSSI measurement resource is the recently received physical downlink shared channel (PDSCH) on the active BWP of the current carrier or the recently monitored control resource set (CORESET) and QCL. The resource being a channel and QCL may be understood as the resource being the time-frequency resource in which the channel is located and the QCL.

[0095] As explained above, the RSSI / CO measurement mechanism and RMTC configuration in the low frequency band are different from those in the high frequency band, so some implementations of RSSI / CO measurement in the low frequency band may no longer be applicable to the high frequency band.

[0096] In one aspect, in a low frequency band, a terminal device may perform RSSI / CO measurement and downlink reception simultaneously. Therefore, a network device may configure the terminal device to perform RSSI / CO measurement and downlink reception simultaneously. However, in a high frequency band, the terminal device may not be able to perform RSSI / CO measurement and downlink reception simultaneously.

[0097] For example, assume that the beam configured by the network device for RSSI / CO measurement on carrier 1 is beam 1, and the beam configured for downlink transmission in the RMTC window on carrier 1 is beam 2. In this case, since the terminal device can only align the beam in one direction at a time, the terminal device cannot simultaneously perform RSSI / CO measurement and downlink reception in the RMTC window on carrier 1.

[0098] In addition, in a carrier aggregation (CA) scenario, the above restriction also exists on Carrier 2, which is in the same frequency band as Carrier 1. During CA, to increase the peak rate of a terminal device, carriers of multiple cells may be aggregated and then provided to the terminal device. Therefore, Carrier 1 and Carrier 2 may be carriers of different cells. In addition, one of Carrier 1 and Carrier 2 may be a primary component carrier, and the other may be a secondary component carrier; or both Carrier 1 and Carrier 2 may be secondary component carriers.

[0099] As shown in Figure 1, when performing RSSI / CO measurement on carrier 1 by using beam 1, the terminal device cannot receive downlink signals on beam 2 on time domain symbols that overlap with the RMTC window on carrier 2. In the above scenario, if the network device still configures the terminal device to perform RSSI / CO measurement and downlink reception simultaneously, downlink reception failure or RSSI / CO measurement failure may occur.

[0100] In another aspect, a new, larger subcarrier spacing, for example, 480 kilohertz (kHz) or 960 kHz, may be introduced in the high frequency band. Compared with a smaller subcarrier spacing (e.g., 120 kHz) at 480 kHz / 960 kHz, the time domain symbol length is significantly reduced and the CP is also very short. Therefore, the beam switching time by the terminal device cannot be ignored. In this scenario, if RSSI / CO measurement is still performed according to the current solution, the measurement result may have a large error.

[0101] For example, as shown in Figure 2a, when the time length occupied by beam switching is the same and the subcarrier spacing is 120 kHz, the proportion of beam switching on one time-domain symbol is very small. In this case, the time for beam switching can be ignored. However, when the subcarrier spacing is 480 kHz or 960 kHz, the length of the time-domain symbol is reduced, so the proportion of beam switching on one time-domain symbol increases significantly, and the time for beam switching can no longer be ignored.

[0102] The beam switching may be adjusting the beam direction, adjusting spatial reception parameters, or the like. The time domain symbol may be the smallest granularity of a time domain resource. For example, the time domain symbol may be an orthogonal frequency division multiplexing (OFDM) symbol or the like.

[0103] For example, as shown in FIG. 2b, the network device configures the terminal device to perform RSSI / CO measurements on carrier 1 by using beam 1, and the beam used for the downlink signal before the RMTC window is assumed to be different from beam 1. In this case, before the measurement, the terminal device needs to perform beam switching to switch to beam 1. If beam switching is performed in the RMTC window, for example, as shown in FIG. 2b, beam switching is performed on the first time-domain symbol in the RMTC window, i.e., part of the time length of the first time-domain symbol is occupied by beam switching, and the power measured by the terminal device on the first time-domain symbol may be smaller than the actual power on the time-domain symbol. As a result, the final measurement result has a large error.

[0104] For example, part of the time of the first time-domain symbol is occupied by beam switching, and the terminal device cannot measure the full power of the entire time-domain symbol (e.g., only 70% of the power on the time-domain symbol is measured). Based on this, the following case may occur: the actual power on the time-domain symbol is greater than the threshold of CO measurement, but only 70% of the power is measured. In this case, the power on the time-domain symbol is determined to be less than the threshold of CO measurement, which will affect the measurement result of CO measurement. In addition, since only 70% of the power on the time-domain symbol is measured, the measurement result of RSSI measurement is small.

[0105] Similarly, if the beam used for the downlink signal on the first time-domain symbol after the RMTC window is different from beam 1, the beam switching performed by the terminal device on the last time-domain symbol in the RMTC window also affects the measurement results.

[0106] In view of this, the present application provides a measurement and scheduling method to reduce measurement errors or reduce resource waste due to downlink reception failure or RSSI / CO measurement failure.

[0107] The technical solutions provided in this application may be applied to various communication systems.

[0115] With reference to the accompanying drawings, the following will describe in detail the method provided in the embodiments of the present application by using the interaction between a terminal device and a network device as an example.

[0116] In the embodiments of the present application, it can be understood that an executing entity can perform some or all of the steps in the embodiments of the present application. These steps or operations are merely examples. The embodiments of the present application may also include performing other operations or various modifications of operations. In addition, steps may be performed in a different order than the order presented in the embodiments of the present application, and all operations in the embodiments of the present application need not be performed.

[0117] 4 shows a measurement and scheduling method according to an embodiment of the present application. The measurement and scheduling method includes the following steps:

[0118] S401: A network device determines an RMTC configuration for a first terminal device.

[0119] The RMTC configuration is used for RSSI measurements and / or CO measurements. For example, the RMTC configuration may be used to configure a first terminal device to perform RSSI measurements and / or CO measurements in an RMTC window on a first carrier.

[0120] Optionally, the RMTC configuration may be used to configure RSSI measurement resources, such as the length and time domain position of the RMTC window, the measurement bandwidth of the RSSI measurement and / or the measurement bandwidth of the CO measurement, and the carrier (referred to as "first carrier" in the following embodiments of the present application) on which the measurement bandwidth of the RSSI measurement and / or the measurement bandwidth of the CO measurement are located. The RMTC measurement resources may be understood to be used for RSSI / CO measurements.

[0121] Furthermore, the RMTC configuration may further include TCI status information, which may indicate an RSSI measurement resource and a reference signal that is a QCL. The terminal device may determine a beam to be used for RSSI measurement and / or CO measurement based on the TCI status information. Of course, the RMTC configuration may not include TCI status information. For details, please refer to the related description of the RMTC configuration. The details will not be described again in this specification.

[0122] S402: The network device sends an RMTC configuration for the first terminal device to the first terminal device. Correspondingly, the first terminal device receives the RMTC configuration from the network device.

[0123] Optionally, after receiving the RMTC configuration, the first terminal device may determine an RSSI measurement resource, for example, an RMTC window and a first carrier, based on the RMTC configuration. When the RMTC configuration includes TCI status information, the beam used for RSSI measurement and / or CO measurement may be further determined based on the RMTC configuration. When the RMTC configuration does not include TCI status information, the first terminal device may determine the RSSI measurement resource to be a recently received PDSCH or a recently monitored CORESET and QCL on the active BWP of the first carrier, and determine the beam used for RSSI measurement and / or CO measurement.

[0124] S403: The first terminal device determines a first time domain symbol group.

[0125] S404: The first terminal device determines the measurement result of the RSSI measurement and / or the measurement result of the CO measurement in the first time-domain symbol group. In other words, the time-domain resource actually used to calculate the measurement result is not the RMTC window but the first time-domain symbol group.

[0126] Optionally, the first terminal device may perform RSSI / CO measurement in the RMTC window and determine the measurement result in the first time domain symbol group. Alternatively, the first terminal device may perform RSSI / CO measurement on the first time domain symbol group and determine the measurement result in the first time domain symbol group. This is not specifically limited in the present application.

[0127] The first time-domain symbol group includes time-domain symbols in the RMTC window other than the second time-domain symbol group. The second time-domain symbol group includes the first N time-domain symbols and / or the last M time-domain symbols in the RMTC window, where N and M are positive integers. In other words, the first time-domain symbol group is located in the RMTC window, and the first time-domain symbol group does not include the first N time-domain symbols and / or the last M time-domain symbols in the RMTC window.

[0128] For example, as shown in Figure 5, the RMTC window constructed by using the RMTC configuration includes 10 time-domain symbols with indices from 0 to 9. Assuming that N and M are equal to 1, i.e., the second time-domain symbol group includes the first and last time-domain symbols in the RMTC window, the first time-domain symbol group includes the time-domain symbols with indices from 1 to 8 in the RMTC window.

[0129] For the second time domain symbol group, in a first possible implementation, if the first subcarrier spacing is greater than or equal to a first threshold, the second time domain symbol group includes the first N time domain symbols and / or the last M time domain symbols in the RMTC window. For example, the first threshold may be 480 kHz. Optionally, if the first subcarrier spacing is less than the first threshold, the first time domain symbol group includes all time domain symbols in the RMTC window, i.e., the first time domain symbol group is identical to the RMTC window (in this case, the second time domain symbol group may be considered not to exist).

[0130] The first subcarrier spacing is the subcarrier spacing of the active BWP of the first carrier, or the first subcarrier spacing is the subcarrier spacing of the RSSI / CO measurement. For example, the subcarrier spacing of the RSSI / CO measurement may be indicated in the RMTC configuration.

[0131] In a second possible implementation, when the first subcarrier spacing is 480 kHz or 960 kHz, the second time domain symbol group includes the first N time domain symbols and / or the last M time domain symbols in the RMTC window. Optionally, when the first subcarrier spacing is 120 kHz, the first time domain symbol group includes all time domain symbols in the RMTC window.

[0132] In a third possible implementation, if the RSSI measurement resource and the first downlink signal are not QCL-ed, the second time domain symbol group includes the first N time domain symbols in the RMTC window; and / or if the RSSI measurement resource and the second downlink signal are not QCL-ed, the second time domain symbol group includes the last M time domain symbols in the RMTC window.

[0133] The fact that a resource and a signal are (or are not) a QCL can be understood as the fact that the resource and the resource carrying the signal are (or are not) a QCL. In addition, in this application, the fact that A and B are not QCLs can also be described as the fact that A and B do not have a QCL relationship. Similarly, the fact that A and B are QCLs can also be described as the fact that A and B have a QCL relationship.

[0134] Optionally, the first downlink signal is a downlink signal on the first time-domain symbol before the RMTC window. For example, the first time-domain symbol before the RMTC window is a time-domain symbol before the RMTC window and adjacent to the first time-domain symbol in the RMTC window. Alternatively, the first downlink signal is a downlink signal before the RMTC window and closest to the RMTC window. When the RSSI measurement resource and the first downlink signal are not QCL, the beam used for the RSSI / CO measurement is different from the beam used for the first downlink signal (e.g., the transmission beam of the first downlink signal), and the first terminal device cannot perform the RSSI / CO measurement and receive the first downlink signal using the same beam. Therefore, the first terminal device needs to perform beam switching to perform the RSSI / CO measurement after receiving the first downlink signal. In this way, "when the RSSI measurement resource and the first downlink signal are not QCL" can also be described as "when beam switching needs to be performed before the RSSI / CO measurement."

[0135] In this case, if beam switching is performed on the first N time-domain symbols in the RMTC window, the measurement results for the first N time-domain symbols will be affected. In this case, the first N time-domain symbols in the RMTC window can be excluded from the first time-domain symbol group to reduce the impact of beam switching on the measurement results and reduce measurement errors.

[0136] For example, as shown in FIG. 6, the RMTC window includes time-domain symbols with indices 10 to 19, and the downlink signals before the RMTC window include downlink signals communicated on time-domain symbols with indices 4 to 6 and downlink signals communicated on time-domain symbols with indices 8 and 9. In this case, the first downlink signals are the downlink signals communicated on time-domain symbols with indices 8 and 9. Assume that the beam used for RSSI / CO measurement is beam 1 and the beam used for the first downlink signals is beam 2. In this case, the second time-domain symbol group includes the first N time-domain symbols in the RMTC window. For example, N is equal to 1. The second time-domain symbol group includes the time-domain symbol with index 10.

[0137] Optionally, the second downlink signal is a downlink signal on the first time domain symbol after the RMTC window, or the second downlink signal is a downlink signal after the RMTC window and closest to the RMTC window. In other words, if the RSSI measurement resource and the resource carrying the second downlink signal are not QCL, the second time domain symbol group includes the last M time domain symbols in the RMTC window. The QCL relationship between the RSSI measurement resource and the resource carrying the second downlink signal may be pre-configured by the network device.

[0138] When the RSSI measurement resource and the second downlink signal are not QCL, the beam used for the RSSI / CO measurement is different from the beam used for the second downlink signal (e.g., the transmission beam of the second downlink signal), and the first terminal device cannot perform the RSSI / CO measurement and receive the second downlink signal using the same beam. Therefore, after the RSSI / CO measurement, the first terminal device needs to perform beam switching to receive the second downlink signal. In this way, "when the RSSI measurement resource and the second downlink signal are not QCL" can also be described as "when beam switching needs to be performed after the RSSI / CO measurement."

[0139] In this case, if beam switching is performed on the last M time-domain symbols in the RMTC window, the measurement results for the last M time-domain symbols will be affected. In this case, the last M time-domain symbols in the RMTC window can be excluded from the first time-domain symbol group to reduce the impact of beam switching on the measurement results and reduce measurement errors.

[0140] For example, as shown in Figure 6, the RMTC window includes time-domain symbols with indices 10 to 19, and the time-domain symbols with indices 20 to 22 are used to carry downlink signals. It is assumed that the beam used for RSSI / CO measurements is beam 1, and the beam used for downlink signals is beam 2. In this case, the second time-domain symbol group includes the last M time-domain symbols in the RMTC window. For example, M is equal to 1. The second time-domain symbol group includes the time-domain symbol with index 19.

[0141] Optionally, if the RSSI measurement resource and the first downlink signal are QCL, the second time domain symbol group does not include the first N time domain symbols in the RMTC window, in other words, the first time domain symbol group also includes the first N time domain symbols in the RMTC window; and / or if the RSSI measurement resource and the second downlink signal are QCL, the second time domain symbol group does not include the last M time domain symbols in the RMTC window, in other words, the first time domain symbol group also includes the last M time domain symbols in the RMTC window, and / or if the first time domain symbol after the RMTC window is not used to carry a downlink signal, the second time domain symbol group does not include the last M time domain symbols in the RMTC window.

[0142] For example, as shown in FIG. 7a, when the RSSI measurement resource and the first downlink signal are QCL and the RSSI measurement resource and the second downlink signal are QCL, the first time-domain symbol group is identical to the RMTC window, and the second time-domain symbol group does not exist. As shown in FIG. 7b, the RSSI measurement resource and the first downlink signal are QCL, and the RSSI measurement resource and the second downlink signal are not QCL. In this case, the second time-domain symbol group includes the last M time-domain symbols in the RMTC window. In FIG. 7b, an example in which M is equal to 1 is used for explanation. As shown in FIG. 7c, the RSSI measurement resource and the first downlink signal are QCL, and the first time-domain symbol after the RMTC window is not used to carry a downlink signal. In this case, the first time-domain symbol group is identical to the RMTC window, and the second time-domain symbol group does not exist. As shown in FIG. 7d, the RSSI measurement resource and the first downlink signal are not QCL, and the first time-domain symbol after the RMTC window is not used to carry a downlink signal. In this case, the second time domain symbol group includes the first N time domain symbols in the RMTC window. In Fig. 7d, an example where N is equal to 1 is used for illustration.

[0143] Optionally, the downlink signal in this application may be at least one of a PDSCH, a physical downlink control channel (PDCCH), a reference signal, and the like. The reference signal may be, for example, a channel state information-reference signal (CSI-RS), a demodulation reference signal (DMRS), or the like, which is not specifically limited in this application.

[0144] When determining the measurement result of the RSSI measurement and / or the measurement result of the CO measurement based on steps S403 and S404, the terminal device excludes the first N time domain symbols and / or the last M time domain symbols in the RMTC window. When performing beam switching on the first N time domain symbols and / or the last M time domain symbols, the first N time domain symbols and / or the last M time domain symbols are not involved in the calculation of the measurement result, thereby reducing the impact of beam switching on the measurement result and thereby reducing the measurement error.

[0145] S405: The network device determines, according to a scheduling rule, transmission resources available for a downlink signal to the first terminal device.

[0146] In a first possible implementation, the scheduling rule includes rule (1): the network device is prohibited from transmitting a downlink signal to the first terminal device on the second time domain symbol group on the first carrier, in other words, the network device does not transmit a downlink signal to the first terminal device on the second time domain symbol group on the first carrier. In other words, the transmission resources available for the downlink signal to the first terminal device do not include the second time domain symbol group on the first carrier. For the first carrier and the second time domain symbol group, please refer to the relevant descriptions of steps S403 and S404. Details will not be described again here.

[0147] From the above analysis, it can be seen that the first terminal device may perform beam switching on the second time domain symbol group. In this scenario, if the network device transmits a downlink signal to the first terminal device on the second time domain symbol group on the first carrier, the first terminal device may be unable to perform downlink reception, resulting in a transmission failure and wasting resources. According to rule (1), the network device is prohibited from transmitting a downlink signal to the first terminal device on the second time domain symbol group on the first carrier. Therefore, the network device may not transmit a downlink signal to the first terminal device on the second time domain symbol group on the first carrier, thereby reducing resource waste.

[0148] In a second possible implementation, the scheduling rule may include rule (2): the network device is prohibited from transmitting a downlink signal that is not an RSSI measurement resource and a QCL to the first terminal device on the first time domain symbol group on the first carrier. In other words, rule (2) can be described as the network being permitted to transmit a downlink signal that is an RSSI measurement resource and a QCL to the first terminal device on the first time domain symbol group on the first carrier. For the first time domain symbol group, please refer to the relevant descriptions of steps S403 and S404. Details will not be described again here.

[0149] In other words, the transmission resources available for the downlink signal to the first terminal device may include a first time domain symbol group on a first carrier, and the downlink signal is an RSSI measurement resource and a QCL.

[0150] Optionally, whether the transmission resources available for the downlink signal to the first terminal device finally include the first time domain symbol group on the first carrier can be determined based on the capability of the terminal device. In this scenario, the method provided in this embodiment of the present application may further include the following steps:

[0151] The first terminal device determines capability information and sends the capability information to the network device. Correspondingly, the network device receives capability information from the terminal device. The capability information indicates whether the first terminal device supports simultaneously performing RSSI / CO measurement and downlink reception when the RSSI measurement resource and the downlink signal are QCL.

[0152] Optionally, after the network device receives the capability information, when the RSSI measurement resource and the downlink signal are QCL, if the capability information indicates that the first terminal device supports simultaneously performing RSSI / CO measurement and downlink reception, the transmission resources available for the downlink signal to the first terminal device may include a first time domain symbol group on a first carrier.If the capability information indicates that the first terminal device does not support simultaneously performing RSSI / CO measurement and downlink reception when the RSSI measurement resource and the downlink signal are QCL, the transmission resources available for the downlink signal to the first terminal device do not include a first time domain symbol group on a first carrier.

[0153] Optionally, when the RSSI measurement resource and the downlink signal are QCL, the first terminal device does not support simultaneously performing RSSI / CO measurement and downlink reception. If the network device still configures the first terminal device to receive the downlink signal while performing RSSI / CO measurement on the RSSI measurement resource, the first terminal device may perform RSSI / CO measurement on the RSSI resource and not receive the downlink signal. In other words, the first terminal device prioritizes performing RSSI / CO measurement, or the priority of RSSI / CO measurement is higher than the priority of downlink reception.

[0154] Optionally, when the RSSI measurement resource and the downlink signal are QCL, the first terminal device supports simultaneously performing RSSI / CO measurement and downlink reception. When the network device configures the first terminal device to receive the downlink signal while performing RSSI / CO measurement on the RSSI measurement resource, the first terminal device may receive the downlink signal while performing RSSI / CO measurement on the RSSI resource.

[0155] According to rule (2), the network device can transmit a downlink signal, which is an RSSI measurement resource and a QCL, to the first terminal device on the first time-domain symbol group on the first carrier. When the downlink signal and the RSSI measurement resource are QCL, the first terminal device can perform RSSI / CO measurement and downlink reception using the same beam, that is, the first terminal device can perform downlink reception while performing RSSI / CO measurement, so that the resource is fully utilized, thereby improving resource utilization and network throughput.

[0156] It should be noted that the scheduling rule in this application may also be referred to as a scheduling constraint, and the scheduling rule and the scheduling constraint may be interchangeable. Of course, the scheduling rule may have another name, for example, the first rule. This is not specifically limited in this application.

[0157] It should be noted that rules (1) and (2) can be used independently; in other words, there is no dependency between rules (1) and (2). Of course, rules (1) and (2) can also be used in combination. For example, a scheduling rule can include both rules (1) and (2).

[0158] Optionally, Rule (1) and Rule (2) may be considered as scheduling constraints of the first carrier or a serving cell on the first carrier. In addition, the scheduling constraint may also be applicable to time domain symbols that fully or partially overlap with the constrained time domain symbol on another carrier in the same frequency band as the first carrier. The constrained time domain symbol in Rule (1) may be a time domain symbol in the second time domain symbol group. The constrained time domain symbol in Rule (2) may be a time domain symbol in the first time domain symbol group. In other words, the scheduling rule may further include Rule (3) and / or Rule (4) below.

[0159] Rule (3) includes: the network device is prohibited from transmitting a downlink signal on the third time domain symbol group on the second carrier to the first terminal device. In other words, the network device does not transmit a downlink signal on the third time domain symbol group on the second carrier to the first terminal device.

[0160] Optionally, the second carrier and the first carrier are in the same frequency band, and further, the second carrier and the first carrier are carriers serving the first terminal device in a carrier aggregation scenario.

[0161] Optionally, the time domain symbols in the third time domain symbol group partially or completely overlap with the time domain symbols in the second time domain symbol group. For example, each time domain symbol in the third time domain symbol group may partially or completely overlap with at least one time domain symbol in the second time domain symbol group; or the time domain position of each time domain symbol in the third time domain symbol group partially or completely overlaps with the time domain position of at least one time domain symbol in the second time domain symbol group. The time domain positions may be absolute time domain positions.

[0162] For example, as shown in Figure 8, the first carrier is carrier 1 and the second carrier is carrier 2. It is assumed that the RMTC window on carrier 1 includes time domain symbols with indices 10 to 19, and the second time domain symbol group includes time domain symbols with indices 10 and 19. In this case, the third time domain symbol group on carrier 2 includes time domain symbols with indices 10, 11, 19, and 20 on carrier 2. The time domain symbols with indices 10 and 11 on carrier 2 partially overlap with the time domain symbol with index 10 on carrier 1; in other words, the time domain position (t3 to t4) of the time domain symbol with index 10 on carrier 2 partially overlaps with the time domain position (t1 to t2) of the time domain symbol with index 10 on carrier 1. The time domain position (t4 to t5) of the time domain symbol with index 11 on carrier 2 partially overlaps with the time domain position (t1 to t2) of the time domain symbol with index 10 on carrier 1.

[0163] According to rule (3), the network device is prohibited from transmitting a downlink signal on the third time domain symbol group on the second carrier to the first terminal device. Therefore, the network device may not transmit a downlink signal on the third time domain symbol group on the second carrier to the first terminal device, thereby reducing resource waste.

[0164] Rule (4) includes: the network device is prohibited from transmitting a downlink signal that is not an RSSI measurement resource and a QCL to the first terminal device on the fourth time domain symbol group on the second carrier. In other words, rule (4) can be explained as the network device is permitted to transmit a downlink signal that is an RSSI measurement resource and a QCL to the first terminal device on the fourth time domain symbol group on the second carrier. For the second carrier, please refer to the relevant explanation in rule (3). Details will not be described again here.

[0165] In other words, the transmission resources available for the downlink signal to the first terminal device may include the fourth time domain symbol group on the second carrier, and the downlink signal is the RSSI measurement resource and the QCL.

[0166] Optionally, the time domain symbols in the fourth time domain symbol group partially or completely overlap with the time domain symbols in the first time domain symbol group. For example, the time domain positions of the fourth time domain symbol group include time domain positions in the RMTC window other than the time domain positions of the third time domain symbol group. The time domain positions may be absolute time domain positions.

[0167] For example, based on the example shown in FIG. 8, the fourth time domain symbol group may include time domain symbols with indices 12-18 on carrier 2.

[0168] Optionally, whether the transmission resource available for the downlink signal to the first terminal device finally includes the fourth time domain symbol group on the second carrier may be determined based on the capability of the terminal device. For details, please refer to the relevant explanation in Rule (2). The details will not be described again in this specification.

[0169] According to rule (4), the network device can transmit a downlink signal, which is an RSSI measurement resource and a QCL, to the first terminal device on the fourth time domain symbol group on the second carrier. When the downlink signal and the RSSI measurement resource are QCL, the first terminal device can perform RSSI / CO measurement and downlink reception using the same beam, that is, the first terminal device can perform downlink reception while performing RSSI / CO measurement, so that the resource is fully utilized, thereby improving resource utilization and network throughput.

[0170] It should be noted that there is no strict execution order between step S405 and step S402. Step S402 can be executed before step S405, or step S405 can be executed before step S402, or step S402 and step S405 can be executed simultaneously, which is not specifically limited in the present application.

[0171] Optionally, after step S405, the method provided in this embodiment of the present application may further include step S406.

[0172] S406: The network device transmits a downlink signal to the first terminal device on the first resource. Correspondingly, the first terminal device receives a downlink signal from the network device on the first resource.

[0173] The first resource is a part or the whole of the transmission resource available for the downlink signal to the first terminal device. When the first resource includes the first time domain symbol group on the first carrier and / or the fourth time domain symbol group on the second carrier, the first resource (or the downlink signal) and the RSSI measurement resource are QCL.

[0174] Based on this solution, when determining the measurement results of the RSSI measurement and / or the CO measurement, the terminal device may exclude the first N time-domain symbols and / or the last M time-domain symbols in the RMTC window. When beam switching is performed on the first N time-domain symbols and / or the last M time-domain symbols, the impact of beam switching on the measurement results can be reduced, thereby reducing measurement errors. In addition, the network device does not transmit downlink signals on the time-domain symbols on which beam switching is performed, thereby avoiding downlink transmission failures caused by beam switching performed by the terminal device, thereby reducing resource waste.

[0175] The method shown in Figure 4 is applicable to a scenario in which beam switching is performed in an RMTC window. In addition, the present application further provides a measurement and scheduling method applicable to a scenario in which beam switching is performed outside an RMTC window. As shown in Figure 9, the measurement and scheduling method comprises the following steps:

[0176] S901: A network device determines an RMTC configuration for a first terminal device.

[0177] S902: The network device sends an RMTC configuration for the first terminal device to the first terminal device. Correspondingly, the first terminal device receives the RMTC configuration from the network device.

[0178] Steps S901 and S902 are the same as steps S401 and S402. For details, please refer to the relevant descriptions of steps S401 and S402. The details will not be described again in this specification.

[0179] S903: The first terminal device determines the measurement result of the RSSI / CO measurement in the RMTC window. In other words, in the method shown in FIG. 9, the time domain resource actually used to calculate the measurement structure is the RMTC window.

[0180] Optionally, the first terminal device may perform RSSI / CO measurement in the RMTC window, and determine the measurement result of the RSSI / CO measurement in the RMTC window.

[0181] S904: The network device determines, according to a scheduling rule, transmission resources available for a downlink signal to the first terminal device.

[0182] In a first possible implementation, the scheduling rule includes rule (5): the network device is prohibited from transmitting a downlink signal to the first terminal device on the fifth time domain symbol group on the first carrier, in other words, the network device does not transmit a downlink signal to the first terminal device on the fifth time domain symbol group on the first carrier. In other words, the transmission resources available for the downlink signal to the first terminal device do not include the fifth time domain symbol group on the first carrier. For the first carrier, please refer to the relevant descriptions of steps S403 and S404. Details will not be described again here.

[0183] The fifth time domain symbol group includes X time domain symbols before the RMTC window of the first terminal device and / or Y time domain symbols after the RMTC window, where X and Y are positive integers. Optionally, the time domain symbols in the fifth time domain symbol group may be used by the first terminal device to perform beam switching, i.e., the first terminal device may perform beam switching on the fifth time domain symbol group.

[0184] When X is equal to 1 and Y is equal to 1, the fifth time domain symbol group includes one time domain symbol before the RMTC window of the first terminal device and / or one time domain symbol after the RMTC window. The one time domain symbol before the RMTC window is adjacent to the first time domain symbol in the RMTC window. The one time domain symbol after the RMTC window is the first time domain symbol after the RMTC window. For example, as shown in FIG. 10, the RMTC window includes time domain symbols with indices 10 to 19. When X is equal to 1 and Y is equal to 1, the fifth time domain symbol group includes time domain symbols with indices 9 and 20.

[0185] When X is greater than 1 and Y is greater than 1, the X time-domain symbols before the RMTC window are X consecutive time-domain symbols, with the last time-domain symbol of the X time-domain symbols adjacent to the first time-domain symbol in the RMTC window. The Y time-domain symbols after the RMTC window are Y consecutive time-domain symbols, with the first time-domain symbol of the Y time-domain symbols adjacent to the last time-domain symbol in the RMTC window. For example, as shown in Figure 11, the RMTC window includes time-domain symbols with indices 10 to 19. When X is equal to 2 and Y is equal to 2, the fifth time-domain symbol group includes time-domain symbols with indices 8, 9, 20, and 21.

[0186] For the fifth time domain symbol group, in a possible implementation, if the first subcarrier spacing is greater than or equal to the first threshold, the fifth time domain symbol group includes X time domain symbols before the RMTC window and / or Y time domain symbols after the RMTC window. For the first subcarrier spacing and the first threshold, please refer to the related description in the method shown in Figure 4. Details will not be described again here. Optionally, if the first subcarrier spacing is smaller than the first threshold, rule (5) may have no effect or may not exist.

[0187] In another possible implementation, when the first subcarrier spacing is 480 kHz or 960 kHz, the fifth time domain symbol group includes X time domain symbols before the RMTC window and / or Y time domain symbols after the RMTC window. Optionally, when the first subcarrier spacing is 120 kHz, rule (5) may have no effect or may not exist.

[0188] In yet another possible implementation, if the RSSI measurement resource and the third downlink signal are not QCL, the fifth time domain symbol group includes X time domain symbols before the RMTC window; and / or if the RSSI measurement resource and the fourth downlink signal are not QCL, the fifth time domain symbol group includes Y time domain symbols after the RMTC window. The resource and signal are (or are not) QCL. For details, please refer to the related description in the method shown in FIG. 4. The details will not be described again in this specification.

[0189] Optionally, the third downlink signal is a downlink signal on X time-domain symbols, or the third downlink signal is a downlink signal that is closest to and X time-domain symbols before the X time-domain symbols. When the RSSI measurement resource and the third downlink signal are not QCLs, the beam used for the RSSI / CO measurement is different from the beam used for the third downlink signal (e.g., the transmission beam of the third downlink signal), and the first terminal device cannot perform the RSSI / CO measurement and receive the third downlink signal using the same beam. Therefore, after receiving the third downlink signal, the first terminal device needs to perform beam switching to perform the RSSI / CO measurement. In this way, "when the RSSI measurement resource and the third downlink signal are not QCLs" can also be described as "when beam switching needs to be performed before the RSSI / CO measurement."

[0190] In this case, if beam switching is performed on X time domain symbols before the RMTC window, the first terminal device may not be able to perform downlink reception on the X time domain symbols. In this scenario, if the network device still transmits downlink signals to the first terminal device on the X time domain symbols on the first carrier, a transmission failure will occur because the first terminal device cannot perform downlink reception, resulting in resource waste. According to rule (5), the network device is prohibited from transmitting downlink signals to the first terminal device on the X time domain symbols on the first carrier, thereby reducing resource waste caused by the network device transmitting downlink signals but the first terminal device not being able to receive the downlink signals.

[0191] For example, as shown in FIG. 11 , the RMTC window includes time-domain symbols with indices 10 to 19, where X is equal to 1. It is assumed that the downlink signals before the RMTC window include downlink signals communicated on time-domain symbols with indices 4 and 5, and downlink signals communicated on time-domain symbols with indices 7 and 8. In this case, the third downlink signal is the downlink signal communicated on the time-domain symbols with indices 7 and 8. It is assumed that the beam used for RSSI / CO measurement is beam 1, and the beam used for the third downlink signal is beam 2. In this case, the fifth time-domain symbol group includes one time-domain symbol before the RMTC window.

[0192] Optionally, the fourth downlink signal is a downlink signal on Y time domain symbols, or the fourth downlink signal is a downlink signal that is closest to Y time domain symbols after Y time domain symbols. In other words, if the RSSI measurement resource and the resource carrying the fourth downlink signal are not QCL, the fifth time domain symbol group includes Y time domain symbols after the RMTC window. A QCL relationship between the RSSI measurement resource and the resource carrying the fourth downlink signal may be pre-configured by the network device.

[0193] When the RSSI measurement resource and the fourth downlink signal are not QCL, the beam used for the RSSI / CO measurement is different from the beam used for the fourth downlink signal (e.g., the transmission beam of the fourth downlink signal), and the first terminal device cannot perform the RSSI / CO measurement and receive the fourth downlink signal using the same beam. Therefore, after the RSSI / CO measurement, the first terminal device needs to perform beam switching to receive the fourth downlink signal. In this way, "when the RSSI measurement resource and the fourth downlink signal are not QCL" can also be described as "when beam switching needs to be performed after the RSSI / CO measurement." In this case, if beam switching is performed on Y time domain symbols after the RMTC window, the first terminal device may not be able to perform downlink reception on the Y time domain symbols. In this scenario, if the network device still transmits downlink signals to the first terminal device on the Y time domain symbols on the first carrier, a transmission failure occurs because the first terminal device cannot perform downlink reception, resulting in wasted resources. According to rule (5), the network device is prohibited from transmitting downlink signals to the first terminal device on Y time domain symbols on the first carrier, thereby reducing the waste of resources caused by the network device transmitting downlink signals but the first terminal device being unable to receive the downlink signals.

[0194] For example, as shown in Figure 11, the RMTC window includes time domain symbols with indices 10 to 19, and the time domain symbols with indices 20 to 22 are used to carry downlink signals. It is assumed that the beam used for RSSI / CO measurements is beam 1, and the beam used for downlink signals is beam 2. In this case, the fifth time domain symbol group includes time domain symbols with indices 20 to 22.

[0195] Optionally, if the RSSI measurement resource and the third downlink signal are QCL, the fifth time domain symbol group does not include X time domain symbols before the RMTC window; and / or if the RSSI measurement resource and the fourth downlink signal are QCL, the fifth time domain symbol group does not include Y time domain symbols after the RMTC window; and / or if the Y time domain symbols after the RMTC window are not used to carry a downlink signal, the fifth time domain symbol group does not include Y time domain symbols after the RMTC window.

[0196] For example, as shown in Figure 12a, if the RSSI measurement resource and the third downlink signal are QCL and the RSSI measurement resource and the fourth downlink signal are QCL, the fifth time domain symbol group does not exist. As shown in Figure 12b, the RSSI measurement resource and the third downlink signal are not QCL, and the RSSI measurement resource and the fourth downlink signal are QCL. In this case, the fifth time domain symbol group includes X time domain symbols before the RMTC window. In Figure 12b, an example where X is equal to 1 is used for explanation.

[0197] In a second possible implementation, the scheduling rule may include rule (6): the network device is prohibited from transmitting a downlink signal that is not an RSSI measurement resource and a QCL to the first terminal device in the RMTC window on the first carrier. In other words, rule (6) may be interpreted as the network device is permitted to transmit a downlink signal that is an RSSI measurement resource and a QCL to the first terminal device in the RMTC window on the first carrier.

[0198] In other words, the transmission resources available for the downlink signal to the first terminal device may include the RMTC window on the first carrier, and the downlink signal is the RSSI measurement resource and the QCL.

[0199] Optionally, whether the transmission resource available for the downlink signal to the first terminal device finally includes the first time domain symbol group on the first carrier can be determined based on the capability of the terminal device. For details, please refer to the relevant description of step S405. The details will not be described again in this specification.

[0200] According to rule (6), the network device may transmit a downlink signal, which is an RSSI measurement resource and a QCL, to the first terminal device in the RMTC window on the first carrier. When the downlink signal and the RSSI measurement resource are QCL, the first terminal device may perform RSSI / CO measurement and downlink reception using the same beam, i.e., the first terminal device may perform downlink reception while performing RSSI / CO measurement, so that the resource is fully utilized, thereby improving resource utilization and network throughput.

[0201] It should be noted that rules (5) and (6) can be used independently; in other words, there is no dependency between rules (5) and (6). Of course, rules (5) and (6) can also be used in combination. For example, a scheduling rule can include both rules (5) and (6).

[0202] Optionally, Rule (5) and Rule (6) are also applicable to time domain symbols that completely or partially overlap with the constrained time domain symbol on another carrier in the same frequency band as the first carrier. The constrained time domain symbol in Rule (5) may be a time domain symbol in the fifth time domain symbol group. The constrained time domain symbol in Rule (6) may be a time domain symbol in the RMTC window. In other words, the scheduling rule may further include Rule (7) and / or Rule (8) below.

[0203] Rule (7): The network device is prohibited from transmitting a downlink signal to the first terminal device on the sixth time domain symbol group on the second carrier, in other words, the network device does not transmit a downlink signal to the first terminal device on the sixth time domain symbol group on the second carrier. For the second carrier, please refer to the relevant explanation in Rule (3). Details will not be described again here.

[0204] Optionally, the time domain symbols in the sixth time domain symbol group partially or completely overlap with the time domain symbols in the fifth time domain symbol group, for example, each time domain symbol in the sixth time domain symbol group may partially or completely overlap with at least one time domain symbol in the fifth time domain symbol group.

[0205] For example, as shown in FIG. 13 , the first carrier is carrier 1 and the second carrier is carrier 2. It is assumed that the RMTC window on carrier 1 includes time domain symbols with indices 10 to 19, and the fifth time domain symbol group includes time domain symbols with indices 9 and 20. In this case, the sixth time domain symbol group on carrier 2 includes time domain symbols with indices 9, 10, 20, and 21 on carrier 2. Rule (8) includes: the network device is prohibited from transmitting a downlink signal that is not an RSSI measurement resource and a QCL to the first terminal device on the seventh time domain symbol group on the second carrier. In other words, rule (8) can be explained as the network device is permitted to transmit a downlink signal that is an RSSI measurement resource and a QCL to the first terminal device on the seventh time domain symbol group on the second carrier.

[0206] In other words, the transmission resources available for the downlink signal to the first terminal device may include the seventh time domain symbol group on the second carrier, and the downlink signal is the RSSI measurement resource and the QCL.

[0207] Optionally, the time domain symbols in the seventh time domain symbol group partially or completely overlap with the time domain symbols in the RMTC window. For example, the time domain positions of the seventh time domain symbol group include time domain positions in the RMTC window other than the time domain positions of the sixth time domain symbol group. The time domain positions may be absolute time domain positions.

[0208] For example, based on the example shown in FIG. 13, the seventh time domain symbol group may include time domain symbols with indices 11-19 on carrier 2.

[0209] Optionally, whether the transmission resource available for the downlink signal to the first terminal device finally includes the seventh time domain symbol group on the second carrier can be determined based on the capability of the terminal device. For details, please refer to the relevant description of step S405. The details will not be described again in this specification.

[0210] It should be noted that there is no strict execution order between step S904 and step S902. Step S902 can be executed before step S904, or step S904 can be executed before step S902, or step S902 and step S904 can be executed simultaneously. This is not specifically limited in the present application.

[0211] Optionally, after step S904, the method provided in this embodiment of the present application may further include step S905.

[0212] S905: The network device transmits a downlink signal to the first terminal device on the second resource. Correspondingly, the first terminal device receives a downlink signal from the network device on the second resource.

[0213] The second resource is a part or the whole of the transmission resource available for the downlink signal to the first terminal device. When the second resource includes the time domain symbols in the RMTC window on the first carrier and / or the seventh time domain symbol group on the second carrier, the second resource (or the downlink signal) and the RSSI measurement resource are QCL.

[0214] Based on the above solution, the network device does not transmit downlink signals on time domain symbols where beam switching is performed, thereby avoiding downlink transmission failures caused by beam switching performed by the terminal device, thereby reducing resource waste.

[0215] The method shown in Figure 4 and the method shown in Figure 9 are applicable to a scenario in which a terminal device performs beam switching in an RMTC window and a scenario in which a terminal device performs beam switching outside an RMTC window, respectively. The two methods may be used separately or in combination. Figure 14 shows an example of a combined method according to the present application. This method may include the following steps:

[0216] Steps S1401 and S1402 are the same as steps S401 and S402. For details, please refer to the relevant descriptions of steps S401 and S402. The details will not be described again in this specification.

[0217] S1403: The first terminal device determines an eighth time domain symbol group.

[0218] When the length of the RMTC window is greater than or equal to the second threshold, the eighth time-domain symbol group includes time-domain symbols other than the ninth time-domain symbol group in the RMTC window. The ninth time-domain symbol group includes the first N time-domain symbols and / or the last M time-domain symbols in the RMTC window, where N and M are positive integers. In other words, when the length of the RMTC window is greater than or equal to the second threshold, the eighth time-domain symbol group may be the first time-domain symbol group, and the ninth time-domain symbol group may be the second time-domain symbol group. In this case, the terminal device may perform the relevant steps of the first terminal device in the method shown in FIG. 4, i.e., the terminal device may perform beam switching in the RMTC window. For details, please refer to the relevant description of the method shown in FIG. 4. The details will not be described again in this specification.

[0219] If the length of the RMTC window is smaller than the second threshold, the eighth time-domain symbol group includes all time-domain symbols in the RMTC window. In other words, when the length of the RMTC window is smaller than the second threshold, the terminal device may execute the relevant steps of the first terminal device in the method shown in Fig. 9, i.e., the terminal device may perform beam switching outside the RMTC window. For details, please refer to the relevant description in the method shown in Fig. 9. Optionally, the length of the RMTC window may be the total number of time-domain symbols in the RMTC window, or may be the time length occupied by the RMTC window.

[0220] S1404: The first terminal device determines the measurement result of the RSSI measurement and / or the measurement result of the CO measurement in the eighth time domain symbol group.

[0221] S1405: The network device determines, according to a scheduling rule, transmission resources available for a downlink signal to the first terminal device.

[0222] The scheduling rule includes: prohibiting the network device from transmitting a downlink signal to the first terminal device on the tenth time domain symbol group on the first carrier.

[0223] When the length of the RMTC window is greater than or equal to the second threshold, the tenth time-domain symbol group includes the first N time-domain symbols and / or the last M time-domain symbols in the RMTC window, where N and M are positive integers. In other words, when the length of the RMTC window is greater than or equal to the second threshold, the tenth time-domain symbol group may be the second time-domain symbol group, and the network device may perform the relevant steps of the network device in the method shown in Figure 4. The scheduling rule includes at least one of rules (1) to (4). For details, please refer to the relevant description in the method shown in Figure 4. The details will not be described again in this specification.

[0224] If the length of the RMTC window is smaller than the second threshold, the 10th time-domain symbol group may include X time-domain symbols before the RMTC window and / or Y time-domain symbols after the RMTC window, where X and Y are positive integers. In other words, when the length of the RMTC window is smaller than the second threshold, the 10th time-domain symbol group may be the 5th time-domain symbol group, and the network device may perform the relevant steps of the network device in the method shown in Figure 9. The scheduling rule includes at least one of rules (5) to (8). For details, please refer to the relevant description in the method shown in Figure 9. The details will not be described again in this specification.

[0225] Optionally, after step S1405, the method provided in this embodiment of the present application may further include step S1406.

[0226] S1406: The network device transmits a downlink signal to the first terminal device on the third resource. Correspondingly, the first terminal device receives a downlink signal from the network device on the third resource.

[0227] Optionally, when the network device and the first terminal device perform related steps in the method shown in Figure 4, the third resource may be the same as the first resource. When the network device and the first terminal device perform related steps in the method shown in Figure 9, the third resource may be the same as the second resource. For details, please refer to the related descriptions. The details will not be described again in this specification.

[0228] Based on this solution, the terminal device can choose to perform beam switching in or outside the RMTC window based on the length of the RMTC window. When the length of the RMTC window is long, beam switching is performed in the RMTC window, so that downlink transmissions can be performed before and after the RMTC window, improving resource utilization and network throughput. When the length of the RMTC window is short, beam switching is performed outside the RMTC window, reducing the impact of beam switching on RSSI / CO measurements and improving the accuracy of the measurement results.
