Communication methods and communication devices

[0001] This application claims priority to Chinese Patent Application No. 202411600505.1, filed with the State Intellectual Property Office of China on November 8, 2024, entitled "Communication Method and Communication Device", the entire contents of which are incorporated herein by reference. Technical Field

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

[0003] To meet the needs of emerging services, a subband full duplex (SBFD) scheme has been proposed. After the introduction of SBFD, the subband configuration of SBFD involves multiple non-contiguous downlink subbands. For this scenario, a specific solution for handling the processing delay of channel state information (CSI) reports has not yet been provided. Summary of the Invention

[0004] This application provides a communication method and a communication device, and provides a specific scheme for the processing latency of CSI reports in SBFD scenarios. Furthermore, the terminal device can perform corresponding processing based on the processing latency of the CSI report, thereby improving the performance of the terminal device.

[0005] Firstly, this application provides a communication method that can be applied to the network side, such as a network or a communication module within a network, or a circuit or chip (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip or system-in-package (SIP) chip containing a modem core) responsible for communication functions within the network. Taking the application of this method to a network device as an example, in this method, the network device generates first information, which includes configuration information for a first channel state information (CSI) report. The first CSI report is associated with a first measurement resource, which is continuous in the frequency domain and spans multiple non-contiguous sub-bands of full-duplex downlink (SBFD) DL sub-bands. The processing delay of the first CSI report includes a first delay and a second delay, where the first delay is Y1 times the third delay, the second delay is Y2 times the fourth delay, and the third and fourth delays constitute the processing delay of the second CSI report. The second CSI report is associated with a second measurement resource, which is continuous in the frequency domain and occupies one SBFD. The DL subband or the second measurement resource is located in a non-SBFD symbol. The first delay is the minimum time interval between the last symbol of the physical downlink control channel (PDCCH) that triggers the first CSI report and the first symbol of the physical uplink shared channel (PUSCH) that carries the first CSI report. The second delay is the minimum time interval between the last symbol of the last measurement resource associated with the first CSI report and the first symbol of the PUSCH that carries the first CSI report. The third delay is the minimum time interval between the last symbol of the PDCCH that triggers the second CSI report and the first symbol of the PUSCH that carries the second CSI report. The fourth delay is the minimum time interval between the last symbol of the last measurement resource associated with the second CSI report and the first symbol of the PUSCH that carries the second CSI report. Here, Y1 and Y2 are values ​​greater than or equal to 1. The first information is then transmitted.

[0006] In this embodiment, after the network device sends the first information to the terminal device, since the first information includes the configuration information of the CSI report, the first CSI report is associated with the first measurement resource, which is continuous in the frequency domain and spans multiple non-contiguous SBFD DL subbands, and the processing delay of the first CSI report includes a first delay that is Y1 times the third delay and a second delay that is Y2 times the fourth delay, it is beneficial for the terminal device to have enough time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0007] In conjunction with the first aspect, in one possible implementation, the first measurement resource includes either Channel State Information-Reference Signal (CSI-RS) resource or Cross-Link Interference-Received Signal Strength Indicator (CLI-RSSI) resource. When the first measurement resource includes CSI-RS resource, Y1 and Y2 are greater than 1; or, when the first measurement resource includes CLI-RSSI resource, Y1 and Y2 are equal to 1.

[0008] In this embodiment, if the first measurement resource includes CSI-RS resources, then Y1 and Y2 are greater than 1. The processing latency configured by the network device for processing the first CSI report to the terminal device is longer than the processing latency for processing the second CSI report. This allows the terminal device sufficient time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting. If the first measurement resource includes CLI-RSSI resources, then Y1 and Y2 are equal to 1. That is, the processing latency configured by the network device for processing the first CSI report to the terminal device can reuse the processing latency for processing the second CSI report. This also allows the terminal device sufficient time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0009] In conjunction with the first aspect, in one possible implementation, when the first measurement resource includes CSI-RS resources, and when the value of the first parameter belongs to the first candidate value and the first CSI report is used for beam measurement reporting, the first delay is the smaller of the first value and the second value, and the second value satisfies the sum of Y2 times the value of the second parameter and the value of the third parameter. Here, the first parameter is μ corresponding to the first subcarrier spacing, the second parameter is related to the beam reporting timing capability of the terminal device, and the third parameter is related to the beam switching timing capability of the terminal device.

[0010] In this embodiment of the application, if the first measurement resource includes CSI-RS resources, when the value of the first parameter belongs to the first candidate value and the first CSI report is used for beam measurement reporting, the first delay is the smaller value of the first value and the second value. The second value satisfies the sum of Y2 times the value of the second parameter and the value of the third parameter, which is beneficial for the terminal device to have enough time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0011] In conjunction with the first aspect, in one possible implementation, when the first measurement resource includes CSI-RS resources, and when the value of the first parameter belongs to the first candidate value and the first CSI report is used for beam measurement reporting, the second delay is Y2 times the value of the second parameter. Here, the first parameter is μ corresponding to the first subcarrier spacing, and the second parameter is related to the beam reporting timing capability of the terminal device.

[0012] In this embodiment of the application, if the first measurement resource includes CSI-RS resources, when the value of the first parameter belongs to the first candidate value and the first CSI report is used for beam measurement reporting, the second delay is Y2 times the value of the second parameter, which is beneficial for the terminal device to have enough time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0013] In conjunction with the first aspect, in one possible implementation, the first candidate value includes at least one of {2, 3, 5, 6}.

[0014] In the embodiments of this application, the first candidate value may include at least one of {2, 3, 5, 6}, which are consistent with the values ​​in the current protocol. This design can provide the value of the first parameter without changing the current protocol, which is conducive to the reliable provision of the processing latency of the first CSI report, thereby giving the terminal device enough time to process the first CSI report, and thus improving the performance of the terminal device's measurement reporting.

[0015] In conjunction with the first aspect, in one possible implementation, if the value of the first parameter is 2, the candidate values ​​of the second parameter include at least one of {8, 14, 28} symbols; or, if the value of the first parameter is 3, the candidate values ​​of the second parameter include at least one of {14, 28, 56} symbols; or, if the value of the first parameter is 5, the candidate values ​​of the second parameter include at least one of {56, 112, 224} symbols; or, if the value of the first parameter is 6, the candidate values ​​of the second parameter include at least one of {112, 224, 448} symbols.

[0016] In this embodiment of the application, the number of symbols included in the candidate values ​​of the second parameter is different for different values ​​of the first parameter. These values ​​are consistent with the values ​​in the current protocol. This design can provide the value of the second parameter without changing the current protocol, which is conducive to the reliable provision of the processing latency of the first CSI report. This allows the terminal device to have enough time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0017] In conjunction with the first aspect, in one possible implementation, if the value of the first parameter is 2 or 3, the candidate values ​​of the third parameter include at least one of the following symbols: {14, 28, 48, 224, 336}; or, if the value of the first parameter is 5, the candidate values ​​of the third parameter include at least one of the following symbols: {56, 112, 192, 896, 1344}; or, if the value of the first parameter is 6, the candidate values ​​of the third parameter include at least one of the following symbols: {112, 224, 384, 1792, 2688}.

[0018] In this embodiment, the number of symbols included in the candidate values ​​of the third parameter varies for different values ​​of the first parameter. These values ​​are consistent with the values ​​in the current protocol. This design can provide the value of the third parameter without changing the current protocol, which is beneficial to the reliable provision of the processing latency of the first CSI report. This allows the terminal device to have enough time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0019] In conjunction with the first aspect, in one possible implementation, the first value is Y2 times the third value, wherein if the value of the first parameter is 2, the third value is 44; or, if the value of the first parameter is 3, the third value is 97; or, if the value of the first parameter is 5, the third value is 388; or, if the value of the first parameter is 6, the third value is 776.

[0020] In this embodiment, if the value of the first parameter is 2, the third value is 44; or, if the value of the first parameter is 3, the third value is 97; or, if the value of the first parameter is 5, the third value is 388; or, if the value of the first parameter is 6, the third value is 776. These values ​​are consistent with those in the current protocol. This design allows the third value to be provided without changing the current protocol, which is beneficial for reliably providing the processing latency of the first CSI report. This gives the terminal device sufficient time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0021] In conjunction with the first aspect, in one possible implementation, Y2 takes the value 2.

[0022] In conjunction with the first aspect, in one possible implementation, the number of channel state information processing units (CPUs) for the first CSI report is 1.

[0023] This application provides the number of CPUs in the first CSI report, that is, the number of CPUs in the first CSI report can be set to 1, which is consistent with the number of CPUs in the current second CSI report. This design can give the number of CPUs in the first CSI report without changing the current protocol, which is simple and reliable.

[0024] Secondly, this application provides a communication method that can be applied to a terminal side, such as a terminal or a communication module within a terminal, or a circuit or chip (such as a modem chip, also known as a baseband chip, or a system-on-a-chip or system-in-package chip containing a modem core) responsible for communication functions within the terminal. Taking the application of this method to a terminal device as an example, in this method, the terminal device receives first information, which includes configuration information for a first Channel State Information (CSI) report. The first CSI report is associated with a first measurement resource, which is continuous in the frequency domain and spans multiple non-contiguous sub-bands of full-duplex downlink (SBFD) DL sub-bands. The processing delay of the first CSI report includes a first delay and a second delay, where the first delay is Y1 times the third delay, the second delay is Y2 times the fourth delay, and the third and fourth delays constitute the processing delay of the second CSI report. The second CSI report is associated with a second measurement resource, which is continuous in the frequency domain and occupies one SBFD. The DL subband or the second measurement resource is located in a non-SBFD symbol. The first delay is the minimum time interval between the last symbol of the physical downlink control channel (PDCCH) that triggers the first CSI report and the first symbol of the physical uplink shared channel (PUSCH) carrying the first CSI report. The second delay is the minimum time interval between the last symbol of the last measurement resource associated with the first CSI report and the first symbol of the PUSCH carrying the first CSI report. The third delay is the minimum time interval between the last symbol of the PDCCH that triggers the second CSI report and the first symbol of the PUSCH carrying the second CSI report. The fourth delay is the minimum time interval between the last symbol of the last measurement resource associated with the second CSI report and the first symbol of the PUSCH carrying the second CSI report. Here, Y1 and Y2 are values ​​greater than or equal to 1. Measurements are performed based on the first information.

[0025] In this embodiment, when the terminal device receives the first information, since the first information includes configuration information for the CSI report and the first CSI report is associated with the first measurement resource, the terminal device can perform measurements based on the first measurement resource. Furthermore, since the first measurement resource is continuous in the frequency domain and spans multiple non-contiguous SBFD DL subbands, and the processing delay of the first CSI report includes a first delay that is Y1 times the third delay and a second delay that is Y2 times the fourth delay, the terminal device can be guaranteed to have sufficient time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0026] In conjunction with the second aspect, in one possible implementation, the first measurement resource includes either Channel State Information-Reference Signal (CSI-RS) resource or Cross-Link Interference-Received Signal Strength Indicator (CLI-RSSI) resource. When the first measurement resource includes CSI-RS resource, Y1 and Y2 are greater than 1; or, when the first measurement resource includes CLI-RSSI resource, Y1 and Y2 are equal to 1.

[0027] In this embodiment, if the first measurement resource includes CSI-RS resources, then Y1 and Y2 are greater than 1. This means the processing latency of the terminal device for processing the first CSI report is longer than the processing latency for processing the second CSI report, allowing the terminal device sufficient time to process the first CSI report and thus improving the measurement reporting performance. If the first measurement resource includes CLI-RSSI resources, then Y1 and Y2 are equal to 1. This means the processing latency of the terminal device for processing the first CSI report can reuse the processing latency for processing the second CSI report, allowing the terminal device sufficient time to process the first CSI report and further improving the measurement reporting performance.

[0028] In conjunction with the second aspect, in one possible implementation, when the first measurement resource includes CSI-RS resources, and when the value of the first parameter belongs to the first candidate value and the first CSI report is used for beam measurement reporting, the first delay is the smaller of the first value and the second value, and the second value satisfies the sum of Y2 times the value of the second parameter and the value of the third parameter. Here, the first parameter is μ corresponding to the first subcarrier spacing, the second parameter is related to the beam reporting timing capability of the terminal device, and the third parameter is related to the beam switching timing capability of the terminal device.

[0029] In this embodiment of the application, if the first measurement resource includes CSI-RS resources, when the value of the first parameter belongs to the first candidate value and the first CSI report is used for beam measurement reporting, the first delay is the smaller value of the first value and the second value. The second value satisfies the sum of Y2 times the value of the second parameter and the value of the third parameter, so that the terminal device has enough time to process the first CSI report, thereby improving the measurement reporting performance of the terminal device.

[0030] In conjunction with the second aspect, in one possible implementation, when the first measurement resource includes CSI-RS resources, when the value of the first parameter belongs to the first candidate value and the first CSI report is used for beam measurement reporting, the second delay is Y2 times the value of the second parameter; wherein, the first parameter is μ corresponding to the first subcarrier spacing, and the second parameter is related to the beam reporting timing capability of the terminal device.

[0031] In this embodiment of the application, if the first measurement resource includes CSI-RS resources, when the value of the first parameter belongs to the first candidate value and the first CSI report is used for beam measurement reporting, the second delay is Y2 times the value of the second parameter, so that the terminal device has enough time to process the first CSI report, thereby improving the performance of the terminal device measurement reporting.

[0032] In conjunction with the second aspect, in one possible implementation, the first candidate value includes at least one of {2, 3, 5, 6}.

[0033] In the embodiments of this application, the first candidate value may include at least one of {2, 3, 5, 6}, which are consistent with the values ​​in the current protocol. This design can provide the value of the first parameter without changing the current protocol, which is beneficial to the reliable provision of the processing latency of the first CSI report. As a result, the terminal device has enough time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0034] In conjunction with the second aspect, in one possible implementation, if the value of the first parameter is 2, the candidate values ​​of the second parameter include at least one of {8, 14, 28} symbols; or, if the value of the first parameter is 3, the candidate values ​​of the second parameter include at least one of {14, 28, 56} symbols; or, if the value of the first parameter is 5, the candidate values ​​of the second parameter include at least one of {56, 112, 224} symbols; or, if the value of the first parameter is 6, the candidate values ​​of the second parameter include at least one of {112, 224, 448} symbols.

[0035] In this embodiment of the application, the number of symbols included in the candidate values ​​of the second parameter is different for different values ​​of the first parameter. These values ​​are consistent with the values ​​in the current protocol. This design can provide the value of the second parameter without changing the current protocol, which is conducive to the reliable provision of the processing latency of the first CSI report. As a result, the terminal device has enough time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0036] In conjunction with the second aspect, in one possible implementation, if the value of the first parameter is 2 or 3, the candidate values ​​of the third parameter include at least one of the following symbols: {14, 28, 48, 224, 336}; or, if the value of the first parameter is 5, the candidate values ​​of the third parameter include at least one of the following symbols: {56, 112, 192, 896, 1344}; or, if the value of the first parameter is 6, the candidate values ​​of the third parameter include at least one of the following symbols: {112, 224, 384, 1792, 2688}.

[0037] In this embodiment of the application, the number of symbols included in the candidate values ​​of the third parameter is different for different values ​​of the first parameter. These values ​​are consistent with the values ​​in the current protocol. This design can provide the value of the third parameter without changing the current protocol, which is conducive to the reliable provision of the processing latency of the first CSI report. As a result, the terminal device has enough time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0038] In conjunction with the second aspect, in one possible implementation, the first value is Y2 times the third value, wherein if the value of the first parameter is 2, the third value is 44; or, if the value of the first parameter is 3, the third value is 97; or, if the value of the first parameter is 5, the third value is 388; or, if the value of the first parameter is 6, the third value is 776.

[0039] In this embodiment, if the value of the first parameter is 2, the third value is 44; or, if the value of the first parameter is 3, the third value is 97; or, if the value of the first parameter is 5, the third value is 388; or, if the value of the first parameter is 6, the third value is 776. These values ​​are consistent with those in the current protocol. This design allows the third value to be provided without changing the current protocol, which is beneficial for reliably providing the processing latency of the first CSI report. This gives the terminal device sufficient time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0040] In conjunction with the second aspect, in one possible implementation, Y2 takes the value 2.

[0041] In conjunction with the second aspect, in one possible implementation, the number of channel state information processing units (CPUs) for the first CSI report is 1.

[0042] This application provides the number of CPUs in the first CSI report, that is, the number of CPUs in the first CSI report can be set to 1, which is consistent with the number of CPUs in the current second CSI report. This design can give the number of CPUs in the first CSI report without changing the current protocol, which is simple and reliable.

[0043] Thirdly, this application provides a communication method that can be applied to the network side, such as a network or a communication module within a network, or a circuit or chip (such as a modem chip, also known as a baseband chip, or a system-on-a-chip or system-in-package chip containing a modem core) responsible for communication functions within the network. Taking the application of this method to a network device as an example, in this method, the network device sends second information, which includes configuration information of a first measurement report. The first measurement report is associated with a third measurement resource, which is continuous in the frequency domain and spans K1 sub-bands of full-duplex downlink SBFD DL sub-bands and K2 sub-bands of full-duplex uplink SBFD UL sub-bands, where K1 and K2 are both positive integers. The device also receives a first measurement report sent by a terminal device, wherein the first measurement report is associated with a portion of the third measurement resource located in at least one SBFD DL sub-band among the K1 SBFD DL sub-bands and / or at least one SBFD UL sub-band among the K2 SBFD UL sub-bands.

[0044] In this embodiment of the application, the network device can send second information including configuration information of a first measurement report to the terminal device. The first measurement report is associated with a third measurement resource. Since the third measurement resource is continuous in the frequency domain and spans K1 SBFD DL subbands and K2 SBFD UL subbands, it is beneficial for the terminal device to perform measurements and report in any one of the SBFD DL subbands, SBFD UL subbands, or SBFD DL and SBFD UL subbands, thereby improving the measurement performance and flexibility of the terminal device.

[0045] In conjunction with the third aspect, in one possible implementation, the first measurement report is associated with at least one of the first measurement method, the second measurement method, and the third measurement method, wherein the first measurement method includes measurement within at least one SBFD DL sub-band among K1 SBFD DL sub-bands, the second measurement method includes measurement within at least one SBFD UL sub-band among K2 SBFD UL sub-bands, and the third measurement method includes measurement within at least one SBFD DL sub-band among K1 SBFD DL sub-bands and at least one SBFD UL sub-band among K2 SBFD UL sub-bands.

[0046] In this embodiment, the first measurement report is associated with at least one of the three measurement methods mentioned above. This is beneficial for the terminal device to perform measurements and report them in the corresponding sub-band based on the measurement method associated with the first measurement report. For example, if the first measurement report is associated with the first measurement method, the terminal device can perform measurements in at least one SBFD DL sub-band among K1 SBFD DL sub-bands. Alternatively, if the first measurement report is associated with the first measurement method and the second measurement method, the terminal device can perform measurements in at least one SBFD DL sub-band among K1 SBFD DL sub-bands, or in at least one SBFD UL sub-band among K2 SBFD UL sub-bands. Or, if the first measurement report is associated with the first measurement method, the second measurement method, and the third measurement method, the terminal device can perform measurements in at least one SBFD DL sub-band among K1 SBFD DL sub-bands, or in at least one SBFD UL sub-band among K2 SBFD UL sub-bands, or simultaneously perform measurements in at least one SBFD DL sub-band among K1 SBFD DL sub-bands and at least one SBFD UL sub-band among K2 SBFD UL sub-bands. This is beneficial for improving the measurement performance and flexibility of the terminal device.

[0047] In conjunction with the third aspect, in one possible implementation, the first measurement report is associated with a first reporting method and / or a second reporting method, wherein the first reporting method corresponds to the first measurement report including a broadband measurement report, and the second reporting method corresponds to the first measurement report including multiple broadband measurement reports.

[0048] In the embodiments of this application, the first measurement report is associated with a first reporting method and / or a second reporting method, which is beneficial for the terminal device to report based on the reporting method associated with the first measurement report. For example, if the first measurement report is associated with the first reporting method, the terminal device can send a broadband measurement report to the network device; or if the first measurement report is associated with the second reporting method, the terminal device can send multiple broadband measurement reports to the network device; or if the first measurement report is associated with the first reporting method and the second reporting method, the terminal device can send one or more broadband measurement reports to the network device, thereby improving the reporting performance and flexibility of the terminal device.

[0049] In conjunction with the third aspect, in one possible implementation, the first measurement method includes measurement within M SBFD DL subbands out of K1 SBFD DL subbands, where M is an integer less than or equal to K1. One broadband measurement report corresponds to M SBFD DL subbands; or, multiple broadband measurement reports include M broadband measurement reports, with each of the M broadband measurement reports corresponding one-to-one with one of the M SBFD DL subbands.

[0050] In this embodiment, the first measurement method includes measurement within M SBFD DL subbands out of K1 SBFD DL subbands. Therefore, for the first reporting method, the first measurement report includes one broadband measurement report corresponding to the M SBFD DL subbands. For the second reporting method, the first measurement report includes multiple broadband measurement reports, including M broadband measurement reports, and each of the M broadband measurement reports corresponds one-to-one with one of the M SBFD DL subbands. This allows the terminal device to send broadband measurement reports of M SBFD DL subbands to the network device based on different reporting methods, thereby improving the reporting performance and flexibility of the terminal device.

[0051] In conjunction with the third aspect, in one possible implementation, the second measurement method includes measurements within N SBFD UL subbands out of K2 SBFD UL subbands, where N is an integer less than or equal to K2. One broadband measurement report corresponds to N SBFD UL subbands; alternatively, multiple broadband measurements include N broadband measurement reports, with each of the N broadband measurement reports corresponding one-to-one with one of the N SBFD UL subbands.

[0052] In this embodiment, the second measurement method includes measurement within N SBFD UL subbands out of K2 SBFD UL subbands. For the first reporting method, the broadband measurement report included in the first measurement report corresponds to N SBFD UL subbands. For the second reporting method, the multiple broadband measurement reports included in the first measurement report include N broadband measurement reports, and the N broadband measurement reports correspond one-to-one with the N SBFD UL subbands. Since the terminal device can send broadband measurement reports of N SBFD UL subbands to the network device based on different reporting methods, it is beneficial to improve the reporting performance and flexibility of the terminal device.

[0053] In conjunction with the third aspect, in one possible implementation, the third measurement method includes measurements within P SBFD DL subbands out of K1 SBFD DL subbands and Q SBFD UL subbands out of K2 SBFD UL subbands, where P is an integer less than or equal to K1 and Q is an integer less than or equal to K2. One broadband measurement report corresponds to P SBFD DL subbands and Q SBFD UL subbands; or, multiple broadband measurement reports include (P+1) broadband measurement reports, where P broadband measurement reports among the (P+1) broadband measurement reports correspond one-to-one with P SBFD DL subbands, and the other broadband measurement report among the (P+1) broadband measurement reports corresponds to Q SBFD UL subbands; or, multiple broadband measurement reports include (Q+1) broadband measurement reports, where Q broadband measurement reports among the (Q+1) broadband measurement reports correspond one-to-one with Q SBFD UL subbands, and the other broadband measurement report among the (Q+1) broadband measurement reports corresponds to P SBFD DL subbands.

[0054] In this embodiment, the third measurement method includes measurements within P SBFD DL subbands out of K1 SBFD DL subbands and Q SBFD UL subbands out of K2 SBFD UL subbands. For the first reporting method, the first measurement report includes one broadband measurement report corresponding to P SBFD DL subbands and Q SBFD UL subbands. For the second reporting method, the first measurement report includes either (P+1) broadband measurement reports or (Q+1) broadband measurement reports. For the (P+1) broadband measurement reports, P broadband measurement reports correspond one-to-one with P SBFD DL subbands, and the remaining broadband measurement report corresponds to Q SBFD UL subbands; for the (Q+1) broadband measurement reports, Q broadband measurement reports correspond one-to-one with Q SBFD UL subbands, and the remaining broadband measurement report corresponds to P SBFD DL subbands. This allows terminal devices to send broadband measurement reports of P SBFD DL subbands and Q SBFD UL subbands to network devices based on different reporting methods, thereby improving the reporting performance and flexibility of terminal devices.

[0055] In conjunction with the third aspect, in one possible implementation, the method further includes: sending first instruction information, the first instruction information being used to instruct the first measurement report to be associated with one of a first measurement method, a second measurement method, and a third measurement method; and / or sending second instruction information, the second instruction information being used to instruct the first measurement report to be associated with a first reporting method or a second reporting method.

[0056] In conjunction with the third aspect, in one possible implementation, the first indication information and / or the second indication information are carried on the second information; or, the first indication information and / or the second indication information are carried on the third information, the third information being used to trigger the measurement reporting corresponding to the first measurement report, wherein the measurement reporting is periodic channel state information (CSI) reporting or semi-persistent CSI reporting.

[0057] In this embodiment of the application, the first indication information and / or the second indication information can be carried in the second information. In other words, the second information sent by the network device to the terminal device includes not only the configuration information of the first measurement report, but also the measurement method used by the terminal device for measurement and / or the reporting method used by the terminal device for reporting, which can save bit overhead.

[0058] The first indication information and / or the second indication information can be carried in the third information, which is used to trigger the measurement reporting corresponding to the first measurement report. In other words, the third information sent by the network device to the terminal device is used to trigger the measurement reporting corresponding to the first measurement report, and also includes the measurement method used by the terminal device for measurement and / or the reporting method used by the terminal device for reporting. This can save bit overhead.

[0059] In conjunction with the third aspect, in one possible implementation, the first measurement report is an aperiodic CSI report, and the processing delay of the first measurement report includes a third delay and a fourth delay. The third delay is the minimum time interval between the last symbol of the physical downlink control channel (PDCCH) that triggers the first measurement report and the first symbol of the physical uplink shared channel (PUSCH) that carries the first measurement report. The fourth delay is the minimum time interval between the last symbol of the last measurement resource associated with the first measurement report and the first symbol of the PUSCH that carries the first measurement report.

[0060] In conjunction with the third aspect, in one possible implementation, the third measurement resource is a Cross-Link Interference-Received Signal Strength Indicator (CLI-RSSI) resource, which is used to measure CLI-RSSI.

[0061] Fourthly, this application provides a communication method that can be applied to the terminal side, such as a terminal or a communication module within a terminal, or a circuit or chip (such as a modem chip, also known as a baseband chip, or a system-on-a-chip or system-in-package chip containing a modem core) responsible for communication functions within the terminal. Taking the application of this method to a terminal device as an example, in this method, the terminal device receives second information, which includes configuration information of a first measurement report. The first measurement report is associated with a third measurement resource, which is continuous in the frequency domain and spans K1 sub-bands of full-duplex downlink SBFD DL sub-bands and K2 sub-bands of full-duplex uplink SBFD UL sub-bands, where K1 and K2 are both positive integers. Based on the second information, the terminal device sends a first measurement report to a network device, wherein the first measurement report is associated with a portion of the third measurement resource located in at least one SBFD DL sub-band among the K1 SBFD DL sub-bands and / or at least one SBFD UL sub-band among the K2 SBFD UL sub-bands.

[0062] In this embodiment, the terminal device receives second information from the network device, including configuration information of a first measurement report. The first measurement report is associated with a third measurement resource, so the terminal device can perform measurements based on the third measurement resource. Since the third measurement resource is continuous in the frequency domain and spans K1 SBFD DL subbands and K2 SBFD UL subbands, the terminal device can perform measurements and report in any one of the SBFD DL subbands, SBFD UL subbands, or SBFD DL and SBFD UL subbands, thereby improving the measurement performance and flexibility of the terminal device.

[0063] In conjunction with the fourth aspect, in one possible implementation, the first measurement report is associated with at least one of the first measurement method, the second measurement method, and the third measurement method, wherein the first measurement method includes measurement within at least one SBFD DL sub-band of K1 SBFD DL sub-bands, the second measurement method includes measurement within at least one SBFD UL sub-band of K2 SBFD UL sub-bands, and the third measurement method includes measurement within at least one SBFD DL sub-band of K1 SBFD DL sub-bands and at least one SBFD UL sub-band of K2 SBFD UL sub-bands.

[0064] In this embodiment, the first measurement report is associated with at least one of the three measurement methods. After receiving the first measurement report, the terminal device can perform measurements and report them in the corresponding sub-band based on the measurement method associated with the first measurement report. For example, if the first measurement report is associated with the first measurement method, the terminal device can perform measurements in at least one SBFD DL sub-band among K1 SBFD DL sub-bands. Alternatively, if the first measurement report is associated with the first measurement method and the second measurement method, the terminal device can perform measurements in at least one SBFD DL sub-band among K1 SBFD DL sub-bands, or in at least one SBFD UL sub-band among K2 SBFD UL sub-bands. Or, if the first measurement report is associated with the first measurement method, the second measurement method, and the third measurement method, the terminal device can perform measurements in at least one SBFD DL sub-band among K1 SBFD DL sub-bands, or in at least one SBFD UL sub-band among K2 SBFD UL sub-bands, or in at least one SBFD DL sub-band among K1 SBFD DL sub-bands and at least one SBFD UL sub-band among K2 SBFD UL sub-bands. Simultaneous measurement within the UL sub-band can improve the measurement performance and flexibility of the terminal equipment.

[0066] In this embodiment, the first measurement report is associated with a first reporting method and / or a second reporting method. After receiving the first measurement report, the terminal device can report based on the reporting method associated with the first measurement report. For example, if the first measurement report is associated with the first reporting method, the terminal device can send a broadband measurement report to the network device. Alternatively, if the first measurement report is associated with the second reporting method, the terminal device can send multiple broadband measurement reports to the network device. Or, if the first measurement report is associated with the first reporting method and the second reporting method, the terminal device can send one or more broadband measurement reports to the network device, thereby improving the reporting performance and flexibility of the terminal device.

For the second reporting method, the multiple broadband measurement reports included in the first measurement report include M broadband measurement reports, and the M broadband measurement reports correspond one-to-one with the M SBFD DL subbands. That is, the terminal device can send broadband measurement reports of M SBFD DL subbands to the network device based on different reporting methods, thereby improving the reporting performance and flexibility of the terminal device.

For the first reporting method, the broadband measurement report included in the first measurement report corresponds to N SBFD UL subbands. For the second reporting method, the multiple broadband measurement reports included in the first measurement report include N broadband measurement reports, and the N broadband measurement reports correspond one-to-one with the N SBFD UL subbands. That is, the terminal device can send broadband measurement reports of N SBFD UL subbands to the network device based on different reporting methods, thereby improving the reporting performance and flexibility of the terminal device.

One broadband measurement report corresponds to P SBFD DL subbands and Q SBFD UL subbands; or, multiple broadband measurement reports include (P+1) broadband measurement reports, where P broadband measurement reports among the (P+1) broadband measurement reports correspond one-to-one with P SBFD DL subbands, and another broadband measurement report among the (P+1) broadband measurement reports corresponds to Q SBFD UL subbands; or, multiple broadband measurement reports include (Q+1) broadband measurement reports, where Q broadband measurement reports among the (Q+1) broadband measurement reports correspond one-to-one with Q SBFD UL subbands, and another broadband measurement report among the (Q+1) broadband measurement reports corresponds to P SBFD DL subbands.

[0072] In this embodiment, the third measurement method includes measurements within P SBFD DL subbands out of K1 SBFD DL subbands and Q SBFD UL subbands out of K2 SBFD UL subbands. For the first reporting method, the first measurement report includes one broadband measurement report corresponding to P SBFD DL subbands and Q SBFD UL subbands. For the second reporting method, the first measurement report includes either (P+1) broadband measurement reports or (Q+1) broadband measurement reports. For the (P+1) broadband measurement reports, P broadband measurement reports correspond one-to-one with P SBFD DL subbands, and the remaining broadband measurement report corresponds to Q SBFD UL subbands; for the (Q+1) broadband measurement reports, Q broadband measurement reports correspond one-to-one with Q SBFD UL subbands, and the remaining broadband measurement report corresponds to P SBFD DL subbands. That is, the terminal device can send broadband measurement reports of P SBFD DL subbands and Q SBFD UL subbands to the network device based on different reporting methods, thereby improving the reporting performance and flexibility of the terminal device.

[0109] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0110] The technical solutions of this application embodiment can be applied to various communication systems, such as: Universal Mobile Telecommunications System (UMTS), Wireless Local Area Network (WLAN), Wireless Fidelity (Wi-Fi) system, 4th generation (4G) mobile communication system, such as Long Term Evolution (LTE) system, 5th generation (5G) mobile communication system, such as New Radio (NR) system, and future evolution communication systems, etc.

[0111] In the embodiments of this application, words such as "exemplarily" and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design scheme described as an "example" in this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the term "example" is intended to present concepts in a concrete manner. In the embodiments of this application, "of," "corresponding, relevant," and "corresponding" may sometimes be used interchangeably, and it should be noted that their intended meanings are consistent unless their distinction is emphasized.

[0112] The communication systems and service scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0113] Figure 1(a) illustrates a possible, non-limiting system diagram. As shown in Figure 1(a), the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. RAN 100 includes at least one RAN node (110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal (120a-120j in Figure 1, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in the figure). Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wired connected to core network 200. The core network devices in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

[0114] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as 4G, 5G mobile communication systems, or future-oriented evolution systems. RAN 100 can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0115] RAN node 110, sometimes also referred to as access network equipment, RAN entity, access node, or network device, constitutes part of the communication system and is used to help terminals achieve wireless access. Multiple RAN nodes 110 in communication system 10 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative. For example, in Figure 1(a), network element 120i can be a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing RAN 100 through network element 120i, network element 120i is a base station; but for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes both referred to as communication devices. For example, in Figure 1(a), network elements 110a and 110b can be understood as communication devices with base station functions, and network elements 120a-120j can be understood as communication devices with terminal functions.

[0116] In one possible scenario, the RAN node can be a device or module located on the network side of the aforementioned communication system 10, possessing corresponding communication functions. The RAN node typically contains communication modules, circuits, or chips that perform the corresponding communication functions. The RAN node is also configured with program instructions for performing the corresponding communication functions, as well as the corresponding program instructions. The RAN node can be a RAN device or network element deployed within the RAN. For example, the RAN node can be a RAN device or a device capable of supporting the RAN device in achieving this function, such as a chip system or a combination device or component capable of implementing access network device functions; this device can be installed within the RAN device. RAN nodes can be access points (APs) in Wi-Fi systems, such as home gateways, routers, servers, switches, and bridges; base stations, base station controllers (BSCs), base transceiver stations (BTSs), home base stations, baseband units (BBUs); wireless relay nodes; wireless backhaul nodes; evolved node Bs (eNBs) in 4G systems; next-generation eNBs (ng-eNBs) during the transition from 4G to 5G systems; next-generation NodeBs (gNBs) in 5G systems; or RAN nodes that implement (partial) gNB functions. RAN nodes can be macro base stations (e.g., 110a in Figure 1(a)), micro base stations or indoor stations (e.g., 110b in Figure 1), relay nodes or donor nodes (also called host nodes), or wireless controllers in CRAN scenarios. Optionally, RAN nodes can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU). All or part of the functions of the RAN node in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform). The RAN node in this application can also be a logical node, logical module, or software capable of implementing all or part of the RAN node functions.

[0117] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with each RAN node performing a portion of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be separate entities or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0118] In some examples, the CU is a logical node carrying the Radio Resource Control (RRC) layer, Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, and other control functions of the access network equipment. The CU connects to network nodes such as the core network through interfaces, which can be interfaces like the E2 interface. Optionally, the CU may possess some core network functions. The CU (e.g., the PDCP layer and higher layers) connects to the DU (e.g., Radio Link Control (RLC) and lower layers) through interfaces, which can be interfaces like the F1 interface. In some examples, these interfaces (e.g., the F1 interface) can provide control plane and user plane functions (e.g., interface management, system information management, user equipment (UE) context management, RRC message transmission, etc.). F1AP is the application protocol for the F1 interface, defining the F1 signaling procedures in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0119] In some examples, the CU can be split into a centralized unit-control plane (CU-CP) and a centralized unit-user plane (CU-UP). The CU-CP is a logical node carrying the control plane part of PDCP (PDCP-C) layer, implementing the CU's control plane functions. The CU-CP can interact with network elements in the core network used to implement control plane functions. The CU-UP is a logical node carrying the user plane part of PDCP (PDCP-U) layer, implementing the CU's user plane functions. The CU-UP can interact with network elements in the core network used to implement user plane functions. The above CU and DU configurations are merely examples; the functions of the CU and DU can be configured as needed. For example, the CU or DU can be configured to have more protocol layer functions, or it can be configured to have only partial protocol layer processing functions. For instance, some functions of the RLC layer and the protocol layer functions above the RLC layer can be set in the CU, while the remaining functions of the RLC layer and the protocol layer functions below the RLC layer can be set in the DU. For example, the functions of CU or DU can be divided according to business type or other system requirements. For instance, based on latency, functions that need to meet the minimum latency requirement can be set in DU, while functions that do not need to meet the latency requirement can be set in CU.

[0120] In some examples, a DU is a logical node that carries the RLC layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0121] In some examples, the RU is a logical node carrying both lower physical layer (PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP transmission reception point (TRP), a remote radio head (RRH), or other similar entities. In some examples, the Low-PHY includes PHY processing functions such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link.

[0122] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through a lower-layer split-control, user, and synchronization (LLS-CUS) interface. LLS-CUS may include interfaces providing control plane (C-plane) and user plane (U-plane) information, respectively. In some examples, the control plane refers to real-time control between the DU and RU. The DU and RU exchange management information via a fronthaul link interface (such as a lower-layer split-management (LLS-M) interface); the user plane refers to non-real-time management operations between the DU and RU.

[0123] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0124] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, a radio access network may also be an open-RAN (O-RAN) architecture. In an O-RAN system, CU may also be called an open CU (open CU, O-CU), DU may also be called an open DU (open DU, O-DU), CU-CP may also be called an open CU-CP (open CU-CP, O-CU-CP), CU-UP may also be called an open CU-UP (open CU-UP, O-CU-UP), and RU may also be called an open RU (open RU, O-RU). Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application may be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0125] The CU is a platform that performs upper-layer L2 and L3 functions. Midhaul and Backhaul interfaces carry traffic between the CU and DU, as well as between the CU and the core network. The DU performs L1 and some L2 functions, while the RU performs L1 computation and RF digital functions; the Fronthaul and Backhaul interfaces carry traffic between the RU and DU, as well as between the CU and DU. An integrated DU includes the functions of both the DU and RU.

[0126] The CU / DU hardware includes a chassis platform, motherboard, peripherals, and cooling system. The motherboard contains processing units, memory, internal I / O interfaces, and external connection ports. Its hardware accelerator is designed with interfaces, and hardware functional components include: storage for software, hardware, and system debugging interfaces, and a single-board management controller.

[0127] DU systems are typically implemented using multi-core processors and one or more hardware accelerators. Parts of the DU protocol stack can be implemented in software running on the multi-core processor, while computationally intensive L1 and L2 functions can be offloaded to a field-programmable gate array (FPGA) / graphics processing unit (GPU)-based hardware accelerator; alternatively, all L1 functions can be offloaded to an FPGA / GPU-based hardware accelerator, while other protocol stack components are implemented in software running on the processor; or the entire protocol stack can be implemented in software running on the processor. The hardware accelerator supports interconnection with x86 or non-x86 processors. Similarly, the accelerator has a multi-channel peripheral component interconnect (PCIe) interface pointing to the CPU and external connections via gigabit Ethernet (GbE) connectivity.

[0128] The RU comprises three parts: the Open Radio Access Network Processing Unit (OPU), the Digital Processing Unit (DPU) of the Open Radio Unit, and the Open-RU (O-RU). The OPU receives Enhanced Common Public Radio Interface (eCPRI) frames from the O-RAN fronthaul and performs fronthaul interface operations, the lowest level L1 layer (coding, scrambling, modulation, layer mapping, precoding), synchronization, beamforming, and resource unit mapping. The OPU can be implemented as a CPU, FPGA, or application-specific integrated circuit (ASIC). The DPU performs synchronization, digital downconversion (DDC), digital upconversion (DUC), crest factor reduction (CFR), and digital pre-distortion (DPD), improving power amplifier efficiency by reducing the peak-to-average power ratio (PAPR) / adjacent channel leakage ratio (ACLR) of the RF front-end. The O-RU's RF processing unit includes a transceiver module, up / down converters, power amplifiers, low-noise amplifiers, and transmit / receive filters. All conversions between the analog and digital domains, including digital-to-analog converters (DACs) and analog-to-digital converters (ADCs), such as RF sampling, the use of RF in up-conversion and down-conversion, and frequency conversion using intermediate frequency (IF) and local oscillator (LO) mixing, are performed within the transceiver module. Note that physical and logical partitioning within the RF processing unit does not require specific boundaries.

[0129] As mentioned above, RAN nodes are sometimes also referred to as network devices. Unless otherwise specified, this application will use the term "network device" to describe them.

[0130] A terminal can be a device or module that accesses the aforementioned communication system 10 and has corresponding communication functions.

A terminal typically contains a communication module, circuit, or chip that performs the corresponding communication functions. The terminal may also be configured with program instructions for performing these communication functions.

[0131] Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart cities, etc. The terminal can be a mobile phone, a personal digital assistant (PDA) computer, a laptop computer, a tablet computer, a drone, a computer with wireless transceiver capabilities, a machine-type communication (MTC) terminal, a virtual reality (VR) terminal, an augmented reality (AR) terminal, an Internet of Things (IoT) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home (e.g., game consoles, smart TVs, smart speakers, smart refrigerators, and fitness equipment), a transportation vehicle with wireless communication capabilities, a communication module, or a roadside unit (RSU) with terminal functionality. The embodiments of this application do not limit the device form of the terminal.

[0132] It should be understood that, in the embodiments of this application, the terminal device or access network device includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, such as Linux, Unix, Android, iOS, or Windows. The application layer includes applications such as browsers, address books, word processing software, and instant messaging software. Furthermore, the embodiments of this application do not particularly limit the specific structure of the execution subject of the method provided in the embodiments of this application, as long as it can communicate according to the method provided in the embodiments of this application by running a program that records the code of the method provided in the embodiments of this application. For example, the execution subject of the method provided in the embodiments of this application can be a terminal device, or a functional module in the terminal device that can call and execute a program.

[0133] Furthermore, various aspects or features of this application can be implemented as methods, apparatus, or articles of manufacture using standard programming and / or engineering techniques. The term "article of manufacture" as used in this application encompasses a computer program accessible from any computer-readable device, carrier, or medium.

[0136] It is understood that Figure 1(a) is a simplified schematic diagram for ease of understanding only. Other possible devices may be included in the communication system, and each device may contain different functional units, which are not shown in Figure 1(a).

[0137] For example, the communication system 10 may further include an application function (AF) network element, which is a control plane network function provided by the operator network for providing application layer information; the communication system 10 may also include a session management function (SMF) network element, which is a control plane network function provided by the operator network. In this embodiment, when the communication system 10 includes both AF and SMF network elements, the AF can send service-related information to the network device through the SMF.

[0138] Figure 1(b) is a schematic diagram of another communication system. This system includes core network equipment, access network equipment, and user equipment.

[0139] Specifically, the BBU in the access network equipment communicates with the core network equipment via the backhaul link, and the RU in the access network equipment communicates with at least one user equipment via the air interface. The BBU communicates with at least one RU via the fronthaul link. The BBU and RU may or may not be co-located. The BBU includes at least one CU and at least one DU, which can communicate via at least one midhaul link.

[0140] To facilitate understanding of the embodiments of this application, the basic concepts involved in this application will be explained first.

[0141] 1. Time Division Duplex (TDD): In a TDD system, time-domain resources are divided into uplink and downlink. For example, one possible uplink / downlink configuration in a TDD system is DDDSU, where D represents a downlink (DL) slot, where each symbol in the downlink slot is a downlink symbol; U represents an uplink (UL) slot, where each symbol in the uplink slot is an uplink symbol; and S represents a special slot, which includes at least flexible symbols.

[0142] In widely used TDD systems, the downlink typically occupies most of the time resources, resulting in poor uplink coverage and high latency, which cannot meet the needs of emerging services (such as VR and AR).

[0143] For example, as shown in Figure 2, the horizontal direction represents the time domain and the vertical direction represents the frequency domain. It includes a set of time-frequency resources for downlink (e.g., downlink data or downlink control information) transmission and a set of time-frequency resources for uplink (e.g., uplink data or uplink control information) transmission. The time domain range occupied by the time-frequency resources for downlink transmission is called the downlink time slot (DL slot), and the time domain range occupied by the time-frequency resources for uplink transmission is called the uplink time slot (UL slot).

[0144] 2. SBFD: To meet the needs of emerging services, the SBFD scheme was proposed. In the SBFD scheme, a carrier (e.g., a component carrier (CC)) is divided into multiple overlapping or non-overlapping subbands, and the transmission directions of different subbands can be different. For example, a carrier may include a non-overlapping first subband and a second subband, and the first and second subbands may have different transmission directions.

[0145] It should be noted that the first subband and the second subband refer to two types of subbands with different transmission directions, and do not mean that a carrier contains only two subbands. For example, a carrier may include subband #1 and subband #2, where subband #1 and subband #2 have different transmission directions. Alternatively, a carrier may include subband #1, subband #2, and subband #3, where subband #1 and subband #3 have the same transmission direction, and subband #1 and subband #2 have different transmission directions.

[0146] In this application, SBFD includes subband overlapping full duplex and subband non-overlapping full duplex.

[0147] To facilitate understanding, the time-frequency division method in the SBFD scheme will be briefly introduced below with reference to Figure 3(a) and (b).

[0148] As shown in Figures 3(a) and (b), the horizontal direction represents the time domain, the vertical direction represents the frequency domain, DL represents downlink resources used for downlink data or control information transmission, and UL represents uplink resources used for uplink data or control information transmission. A time period that includes only downlink resources is called a downlink time slot or downlink symbol; a time period that includes only uplink resources is called an uplink time slot or uplink symbol; and a time period that includes both downlink and uplink resources is called an SBFD time slot or SBFD symbol. In this application, an SBFD time slot, SBFD symbol, or time period representing both downlink and uplink resources can be referred to as an SBFD time unit.

[0149] 3. SBFD Time Unit: This includes uplink frequency resources and downlink frequency resources. The uplink frequency resources are used for uplink transmission, and the downlink frequency resources are used for downlink transmission. It can be understood that the SBFD time unit includes subbands for uplink and downlink transmission, and the base station can use these subbands to perform SBFD operations. In this embodiment, when the time unit is a symbol, the SBFD time unit is an SBFD symbol. When the time unit is a time slot, subframe, half-frame, frame, mini-subframe, mini-time slot, or transmission occasion (TO), the SBFD time unit can refer to a time unit containing an SBFD symbol.

[0150] It should be noted that the frequency domain resources on the SBFD time unit of this application may include downlink (DL) subbands and uplink (UL) subbands. To avoid cross-link interference between downlink transmissions on the DL subband and uplink transmissions on the UL subband, a guard band may be defined between the DL subband and the UL subband. This application does not limit whether a guard band exists between the DL subband and the UL subband, or whether transmission can be performed on the guard band if it exists. Furthermore, this application does not limit whether the DL subband and the UL subband can overlap (e.g., they may not overlap at all, or they may partially overlap, or they may completely overlap).

[0151] For example, regarding the configuration of SBFD, depending on whether a time slot contains both SBFD symbols and non-SBFD symbols, there are two possible configuration methods:

[0152] 1) SBFD configuration is at the time slot level, meaning that the symbols contained in a time slot are either all configured as SBFD symbols or all configured as non-SBFD symbols.

[0153] 2) SBFD configuration is symbol-level, meaning that some of the symbols contained in a time slot can be configured as SBFD symbols, while others can be configured as non-SBFD symbols.

[0154] In this context, the SBFD symbol can be considered as a symbol configured with SBFD, and the non-SBFD symbol can be considered as a symbol without SBFD. This application does not impose any limitations on the configuration of SBFD.

[0155] 4. Subband: A subband is a portion of a carrier frequency band, i.e., one or more consecutive PRBs in the frequency domain. In this application, the subband used for uplink transmission is called the uplink subband, and the subband used for downlink transmission is called the downlink subband. Subband can also be understood as frequency resource. Currently, base stations support FD (e.g., SBFD and SFFD mentioned above), meaning that in a single time slot, transmission can occur simultaneously on the uplink subband and reception on the downlink subband. Terminal equipment only supports half-duplex (HF) SBFD, meaning that in a single time slot, transmission can only occur on the uplink subband, or reception can only occur on the downlink subband.

[0156] 5. Time-frequency resources: In this embodiment, data or information can be carried by time-frequency resources. These time-frequency resources may include resources in the time domain (i.e., time-domain resources) and resources in the frequency domain (i.e., frequency-domain resources).

[0157] In the time domain, time-domain resources can include one or more time-domain units (or time units), and a time unit can include several time-domain resources. A time-domain unit is, for example, a radio frame (RF). The time-domain resources included within a time-domain unit can be, for example, a subframe, a frame, a half-subframe or half-frame, a slot, a mini-slot, a partial slot, or an OFDM symbol; alternatively, a time-domain unit may also be a collection of one or more time-domain resources, such as one or more OFDM symbols within a time slot, for example, the number of such one or more might be 6, 7, 12, or 14. One or more time units can be continuous or discrete in time. Furthermore, the duration of a time slot can be related to the sub-carrier space (SCS) interval. For example, when the subcarrier spacing is 15kHz, the duration of one time slot is 1 millisecond (ms); when the subcarrier spacing is 30kHz, the duration of one time slot is 0.5ms; and when the subcarrier spacing is 60kHz, the duration of one time slot is 0.25ms. Similarly, it can be deduced that when the subcarrier spacing is 15×2... μ At kHz, the duration of one time slot is 2. μ ms, μ = 0, 1, 2, ..., μ is a non-negative integer.

[0158] In the frequency domain, frequency domain resources can include one or more frequency domain units. A frequency domain unit can be a resource element (RE), a resource block (RB), a subchannel, a resource pool, a bandwidth, a bandwidth part (BWP), a carrier (CC), a channel, or an interlaced RB, etc.

[0159] Currently, UEs support CSI measurement and reporting. The basic principle is that the base station sends measurement signals, such as channel state information reference signals (CSI-RS), and the UE performs measurements based on these signals and reports the results to the base station. Depending on the triggering method for CSI measurement reporting, existing CSI measurement reporting includes aperiodic reporting, periodic reporting, and semi-persistent reporting.

[0160] For CSI measurement and reporting, the protocol defines the UE's processing capacity and processing latency. Regarding the processing latency of the CSI report, the current protocol primarily defines the minimum processing latency (Z, Z') for aperiodic CSI reports triggered via the physical uplink control channel (PDCCH) and performed on the physical uplink share channel (PUSCH), as shown in Figure 5.

[0161] Where Z is the minimum time interval from the end of the last symbol of the PDCCH to the beginning of the first symbol of the PUSCH. Z' is the minimum time interval from the end of the last symbol of the aperiodic CSI-RS resource used for channel measurement, the aperiodic channel state information interference measurement (CSI-IM) used for interference measurement, and the aperiodic non-zero power channel state information-reference signal (NZP CSI-RS) used for interference measurement to the beginning of the first symbol of the PUSCH.

[0162] in, M represents the number of CSI reports to be updated. Z(m) and Z'(m) correspond to the m-th CSI report to be updated, and their values ​​can be determined from Table 1 or Table 2 below based on the content carried in the SCS and CSI report.

[0163] Table 1

[0164] Table 2

[0165] In Tables 1 and 2, μ represents the minimum value of {μPDCCH, μCSI-RS, μUL}. μPDCCH corresponds to the subcarrier spacing of PDCCH, μCSI-RS corresponds to the minimum subcarrier spacing of CSI-RS triggered by downlink control information (DCI), and μUL corresponds to the subcarrier spacing of PUSCH carrying CSI report.

[0166] 1) If max{μPDCCH,μCSI-RS,μUL}≤3, and the CSI report is non-periodic, and the PUSCH carrying the CSI report has neither a transport block (TB) nor a hybrid automatic repeat request-acknowledgement (HARQ-ACK) transmission, and 0 channel state information processing units (CPUs) are occupied, and the CSI to be transmitted corresponds to only one CSI, and the CSI is wideband granular, and the corresponding CSI-RS resource has at most 4 CSI-RS ports and no channel state information resource index (CRI) is reported, and the codebook type is set to type I single panel or the reporting quantity is set to CRI-rank-indication-channel quality. If indicator, cri-RI-CQI', then (Z(m),Z'(m)) takes the value (Z1,Z'1) in Table 1.

[0167] 2) If the CSI to be transmitted is wideband granularity, where the CSI corresponds to a unique resource with no more than 4 ports and no CRI is reported, and the codebook type is set to 'typeI-SinglePanel' or the reporting quantity is set to 'cri-RI-CQI', then (Z(m),Z'(m)) takes the value (Z1,Z'1) in Table 2.

[0168] 3) If the CSI to be transmitted is wideband granularity, and the reporting quantity is set to single-sideband modulation-index-signal to interference plus noise ratio (ssb-Index-SINR), channel state information resource index-signal to interference plus noise ratio (cri-SINR), single-sideband modulation-index-signal to interference plus noise ratio-index (ssb-Index-SINR-Index), or (cri-signal to interference plus noise ratio'cri-SINR-Index', then (Z(m),Z'(m)) takes the value (Z1,Z'1) in Table 2.

[0169] 4) If the reported quantity is set to Channel State Information Resource Index - Reference Signal Received Power (CSI - CRI - RSRP), 'SSB - Index - RSRP', 'CRI - RSRP - Index' or 'SSB - Index - RSRP - Index', that is, when the CSI report is used for beam measurement reporting, then (Z(m), Z'(m)) takes the value (Z3, Z'3) in Table 2. In Table 2, KB1, KB2, KB3, and KB4 are determined based on the beam switching timing capability reported by the UE, and X0, X1, X2, X3, X4, X5, and X6 are determined based on the beam reporting timing capability reported by the UE.

[0170] 5) Otherwise, (Z(m),Z'(m)) takes the value (Z2,Z'2) in Table 2.

[0171] After the introduction of SBFD, if the SBFD subband is configured as shown in Figure 3(a) above, there are two non-contiguous SBFD downlink subbands. Therefore, for the existing CSI measurement process, the base station needs to send measurement signals such as CSI-RS in two non-contiguous downlink subbands. Similarly, the UE also needs to receive and measure measurement signals such as CSI-RS in two non-contiguous downlink subbands. For this scenario, no specific solution has yet been provided for the CSI report processing latency.

[0172] Furthermore, in SBFD, the signal power within a sub-band leaks into adjacent sub-bands, causing interference between the uplink and downlink, known as cross-link interference (CLI).

[0173] Figure 4 is a schematic diagram of CLI in the SBFD scenario. According to the source of interference, cross-link interference includes two main categories: (1) one is cross-link interference between UEs (UE-to-UE CLI), which mainly refers to the interference caused by the uplink signal sent by one UE in the same cell to the downlink signal received by another UE in the same cell or a neighboring cell; (2) the other is cross-link interference between base stations (gNB-to-gNB CLI), which mainly refers to the interference caused by the downlink signal sent by one base station to the uplink signal received by another base station.

[0174] For the newly introduced UE-to-UE CLI in subband duplex scenarios, the industry is discussing the introduction of a Layer 1 (L1) UE-to-UE CLI measurement and reporting mechanism. L1 level UE-to-UE CLI measurement and reporting refers to UE-to-UE CLI measurement and reporting performed at the NR protocol physical layer or data link layer level. Its basic principle is that one UE transmits a signal, another UE measures the signal transmitted by the former, and sends the corresponding measurement results to the base station. Currently, there are three specific measurement methods:

[0175] Method 1: The UE measures SRS-RSRP based on SRS resources within the SBFD UL subband range.

[0176] Method 2: The UE measures CLI-RSSI based on the cross-link interference-received signal strength indicator (CLI-RSSI) measurement resource within the SBFD DL subband(s) range.

[0177] Method 3: The UE measures CLI-RSSI based on CLI-RSSI measurement resources within the SBFD UL subband range.

[0178] Currently, industry discussions focus on reusing existing CSI measurement and reporting mechanisms for L1-level UE-to-UE CLI measurement and reporting. This involves configuring measurement resources for UE-to-UE CLI measurements within a single CSI measurement report. The UE then performs UE-to-UE CLI measurements and reports based on this CSI measurement, instead of relying on CSI-RS transmitted by the base station for measurement and reporting. Therefore, it can be argued that after the introduction of SBFD, CSI measurement reporting can be divided into two categories: one is channel state information measurement and reporting based on reference signals such as CSI-RS, and the other is UE-to-UE CLI measurement and reporting based on UE-to-UE CLI measurement resources.

[0179] If a CSI report is used for UE-to-UE CLI measurement, and the measurement method is Method 2 mentioned above, that is, the UE measures CLI-RSSI based on CLI-RSSI measurement resources within the SBFD DL subband(s), and the CLI-RSSI measurement resources span two non-contiguous SBFD DL subband(s), no specific solution has been given for the processing latency of CSI reports in this scenario.

[0180] Based on this, this application provides a communication method that provides a specific solution for the processing latency of CSI reports in the above two scenarios. Furthermore, the terminal device can perform corresponding processing based on the processing latency of the CSI report, thereby improving the performance of the terminal device.

[0181] It should be understood that the communication method provided in this application embodiment can be applied to systems that communicate using multi-antenna technology, such as the communication system 10 shown in Figure 1(a) or the communication system shown in Figure 1(b). The communication system may include at least one network device and at least one terminal device.

[0182] The communication between different devices involved in the embodiments of this application can refer to direct communication between different devices (i.e., without the need for relaying or forwarding by other devices), or communication between different devices through other devices (i.e., requiring relaying or forwarding by other devices), or communication between a functional unit within a device and other devices through another functional unit. In other words, "sending information to a terminal device" in this application can be understood as the destination of the information being the terminal device. This can include sending information directly or indirectly to the terminal device. "Receiving information from a network device" can be understood as the source of the information being the network device, and can include receiving information directly or indirectly from the network device. Information may undergo necessary processing between the source and destination, such as format changes, digital-to-analog conversion, amplification, filtering, etc., but the destination can understand the valid information from the source. Similar expressions in this application can be understood in a similar way, and will not be elaborated further here.

[0183] Figure 5 is a schematic diagram of a communication method 500 provided in an embodiment of this application. The communication method may include steps 510 to 540.

[0184] 510. Generate first information, which includes configuration information for a first CSI report. The first CSI report is associated with a first measurement resource, which is continuous in the frequency domain and spans multiple non-contiguous SBFD DL subbands. The processing delay of the first CSI report includes a first delay and a second delay. The first delay is Y1 times the third delay, and the second delay is Y2 times the fourth delay. The third and fourth delays constitute the processing delay of the second CSI report. The second CSI report is associated with a second measurement resource, which is continuous in the frequency domain and occupies one SBFD. The DL subband or the second measurement resource is located on a non-SBFD symbol. The first delay is the minimum time interval between the last symbol of the PDCCH that triggers the first CSI report and the first symbol of the PUSCH that carries the first CSI report. The second delay is the minimum time interval between the last symbol of the last measurement resource associated with the first CSI report and the first symbol of the PUSCH that carries the first CSI report. The third delay is the minimum time interval between the last symbol of the PDCCH that triggers the second CSI report and the first symbol of the PUSCH that carries the second CSI report. The fourth delay is the minimum time interval between the last symbol of the last measurement resource associated with the second CSI report and the first symbol of the PUSCH that carries the second CSI report. Here, Y1 and Y2 are values ​​greater than or equal to 1.

[0185] 520, send the first message.

[0186] In this embodiment, steps 510-520 can be executed by a network device, a module of the network device (e.g., a chip, chip system, or processor), or a logical node, logical module, or software capable of implementing all or part of the functions of the network device. For ease of description, the following will uniformly use a network device as an example.

[0187] In this embodiment, the first CSI report is associated with a first measurement resource. The first measurement resource is continuous in the frequency domain and spans multiple non-contiguous SBFD DL sub-bands. This can be understood as the first measurement resource simultaneously falling within multiple non-contiguous SBFD DL sub-bands in the frequency domain; or it can be understood as the first measurement resource comprising a first part and a second part, the first part being located in the first SBFD DL sub-band in the frequency domain, and the second part being located in the second SBFD DL sub-band in the frequency domain. The first SBFD DL and the second SBFD DL sub-bands are non-contiguous in the frequency domain. See Figure 6 for details. Referring to Figure 6, it can be seen that the first measurement resource is continuous in the frequency domain and spans two non-contiguous SBFD DL sub-bands, which are DL1 sub-band 1 and DL2 sub-band in Figure 6.

[0188] In this embodiment, the second CSI report is associated with a second measurement resource. The second measurement resource is continuous in the frequency domain and occupies one SBFD DL sub-band. This can be understood as the second measurement resource falling within a continuous SBFD DL sub-band in the frequency domain, as shown in Figure 7(a). Referring to Figure 7(a), it can be seen that the second measurement resource is continuous in the frequency domain and occupies one SBFD DL sub-band, which is the DL1 sub-band in Figure 7(a).

[0189] Alternatively, the second measurement resource may be located in a non-SBFD symbol. This can be understood as the second measurement falling within a subband of the non-SBFD symbol in the frequency domain, as shown in Figure 7(b). Referring to Figure 7(b), it can be seen that the second measurement resource is located in a non-SBFD symbol, that is, the second measurement resource is located in the DL subband of TDD in the frequency domain.

[0190] In this embodiment, the third delay and the fourth delay are the processing delays of the second CSI report. The third delay is the minimum time interval between the last symbol of the PDCCH that triggers the second CSI report and the first symbol of the PUSCH carrying the second CSI report. Here, the third delay can be Z1 in Table 1 above, or Z1, Z2, and Z3 in Table 2. The fourth delay is the minimum time interval between the last symbol of the last measurement resource associated with the second CSI report and the first symbol of the PUSCH carrying the second CSI report. Here, the fourth delay can be Z1' in Table 1 above, or Z1', Z2', and Z3' in Table 2.

[0191] In this embodiment, the processing latency of the first CSI report includes a first latency and a second latency. The first latency is Y1 times the third latency, and the second latency is Y2 times the fourth latency. Referring to Table 2 above, taking μ as an example, the first latency is Y1 times min(44,X2+KB1), and the second latency is Y2 times X2.

[0192] 530, receiving the first message.

[0193] 540, Measurement based on the first information.

[0194] In this embodiment, steps 530-540 can be executed by the terminal device, or by a module of the terminal device (e.g., a chip, chip system, or processor), or by a logic node, logic module, or software capable of implementing all or part of the terminal device's functions. For ease of description, the terminal device will be used as an example throughout this document.

[0195] In this embodiment, when the terminal device receives the first information, since the first information includes configuration information for the CSI report and the first CSI report is associated with the first measurement resource, the terminal device can perform measurements based on the first measurement resource. Furthermore, since the first measurement resource is continuous in the frequency domain and spans multiple non-contiguous SBFD DL subbands, and the processing delay of the first CSI report includes a first delay that is Y1 times the third delay and a second delay that is Y2 times the fourth delay, the terminal device can be guaranteed to have sufficient time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0196] Optionally, in one embodiment, the first measurement resource includes a CSI-RS resource or a CLI-RSSI resource. When the first measurement resource includes a CSI-RS resource, Y1 and Y2 are greater than 1; or, when the first measurement resource includes a CLI-RSSI resource, Y1 and Y2 are equal to 1.

[0197] In this embodiment, if the first measurement resource includes CSI-RS resources, then Y1 and Y2 are greater than 1, meaning the first delay is greater than the third delay, and the second delay is greater than the fourth delay. In this case, when the terminal device performs measurements based on the first measurement resource, the processing delay for processing the first CSI report is longer than the processing delay for processing the second CSI report, thus ensuring that the terminal device has sufficient time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0198] If the first measurement resource includes CSI-RS resources, then Y1 and Y2 equal 1, meaning the first delay equals the third delay, and the second delay equals the fourth delay. In other words, in this case, when the terminal device performs measurements based on the first measurement resource, the processing delay of the terminal device for processing the first CSI report can reuse the current (Z, Z'). That is, the processing delay of the first CSI report at this time is consistent with (Z, Z') in Table 1 or Table 2 above, thereby ensuring that the terminal device has sufficient time to process the first CSI report, and thus improving the performance of the terminal device's measurement reporting.

[0199] As mentioned above, the third delay can be Z3 in Table 2, and the fourth delay can be Z3' in Table 2. When μ in Table 2 is a value greater than or equal to 2, Z3 takes the smaller of the two values. In this case, the first and second delays are explained in detail.

[0200] Optionally, in one embodiment, when the first measurement resource includes CSI-RS resources, when the value of the first parameter belongs to the first candidate value and the first CSI report is used for beam measurement reporting, the first delay is the smaller value of the first value and the second value, and the second value satisfies the sum of Y2 times the value of the second parameter and the value of the third parameter. Here, the first parameter is μ corresponding to the first subcarrier spacing, the second parameter is related to the beam reporting timing capability of the terminal device, and the third parameter is related to the beam switching timing capability of the terminal device.

[0201] Optionally, in one embodiment, when the first measurement resource includes CSI-RS resources, when the value of the first parameter belongs to the first candidate value and the first CSI report is used for beam measurement reporting, the second delay is Y2 times the value of the second parameter. Here, the first parameter is μ corresponding to the first subcarrier spacing, and the second parameter is related to the beam reporting timing capability of the terminal device.

[0202] Optionally, in one embodiment, the first candidate value includes at least one of {2, 3, 5, 6}.

[0203] When the value of the first parameter belongs to one of {2, 3, 5, 6} and the first CSI report is used for beam measurement reporting, the first delay and the second delay are shown in Table 3.

[0204] Table 3

[0205] Referring to Table 3, the first parameter is μ in Table 3 above, the second parameter is X (including X2, X3, X5, X6) in Table 3 above, and the third parameter is KB (including KB1, KB2, KB3, KB4) in Table 3 above. Among them, when the value of μ is different, the values of the first delay and the second delay may change. For example, when μ is 2, the first delay is the smaller value between Y2 * 44 and Y2 * X2 + KB1, and the second delay is Y2 * X2. When μ is 3, the first delay is the smaller value between Y2 * 97 and Y2 * X3 + KB2, and the second delay is Y2 * X3.

[0206] In the embodiments of the present application, Y1 and Y2 may be equal or unequal, which is not limited.

[0207] For example, when μ is 2, the first delay is the smaller value between Y2 * 44 and Y2 * X2 + KB1. If Y2 * 44 < Y2 * X2 + KB1, the first delay is Y2 * 44, that is, it is Y2 times larger than in the same case in Table 2, so Y1 * 44 = Y2 * 44, and at this time Y1 = Y2; if Y2 * 44 > Y2 * X2 + KB1, the first delay is Y2 * X2 + KB1, so Y1 * (X2 + KB1) = Y2 * X2 + KB1. At this time, if Y2 = 1, then Y1 = Y2; if Y2 > 1, then Y1 ≠ Y2.

[0208] It should be noted that in some possible embodiments, the network device may directly send the specific value of the processing delay of the first CSI report to the terminal device. For example, when μ is 2 and Y2 = 2, the network device may send the processing delay of the first CSI report to the terminal device as (min(2 * 44, 2 * X2 + KB1), 2 * X2).

[0209] In the embodiments of the present application, if the first measurement resource includes CSI-RS resources, when the value of the first parameter belongs to the first candidate value and the first CSI report is used for beam measurement reporting, the first delay is the smaller value between the first value and the second value, and the second value satisfies the sum of Y2 times the value of the second parameter and the value of the third parameter. The second delay is Y2 times the value of the second parameter, so that the terminal device can have enough time to process the first CSI report, and thus the measurement reporting performance of the terminal device can be improved.

[0210] The candidate values of the second parameter and the third parameter will be introduced below.

[0211] Optionally, in one embodiment, if the value of the first parameter is 2, the candidate values ​​of the second parameter include at least one of {8, 14, 28} symbols; or, if the value of the first parameter is 3, the candidate values ​​of the second parameter include at least one of {14, 28, 56} symbols; or, if the value of the first parameter is 5, the candidate values ​​of the second parameter include at least one of {56, 112, 224} symbols; or, if the value of the first parameter is 6, the candidate values ​​of the second parameter include at least one of {112, 224, 448} symbols.

[0212] In this embodiment, if the value of the first parameter is 2, the candidate values ​​of the second parameter include at least one of the following {8, 14, 28} symbols. That is, if μ in Table 3 is 2, then the candidate values ​​of X (such as X2, X3, X5, X6) in Table 3 include at least one of the following {8, 14, 28} symbols. If the value of the first parameter is 3, the candidate values ​​of the second parameter include at least one of the following {14, 28, 56} symbols. That is, if μ in Table 3 is 3, then the candidate values ​​of X (such as X2, X3, X5, X6) in Table 3 include at least one of the following {14, 28, 56} symbols. If the value of the first parameter is 5, the candidate values ​​of the second parameter include at least one of the following {56, 112, 224} symbols. That is, if μ in Table 3 is 5, then the candidate values ​​of X (such as X2, X3, X5, X6) in Table 3 include at least one of the following {56, 112, 224} symbols. If the value of the first parameter is 6, the candidate values ​​of the second parameter include at least one of the symbols {112, 224, 448}. That is, if μ in Table 3 above is 3, then the candidate values ​​of X (such as X2, X3, X5, X6) in Table 3 above include at least one of the symbols {112, 224, 448}.

[0213] In other words, taking μ as an example, if μ in Table 3 above is 2, then the candidate values ​​for X (such as X2, X3, X5, X6) in Table 3 include one or more of the {8, 14, 28} symbols. When the candidate values ​​for X in Table 3 include one value from the {8, 14, 28} symbols, that value can be, for example, {8}; when the candidate values ​​for X in Table 3 include two values ​​from the {8, 14, 28} symbols, those two values ​​can be, for example, {8, 14}; when the candidate values ​​for X in Table 3 include three values ​​from the {8, 14, 28} symbols, those three values ​​can be, for example, {8, 14, 28}. Other possible cases will not be detailed further.

[0214] In this embodiment, if the value of the first parameter is 2, the candidate values ​​of the second parameter include at least one of {8, 14, 28}; or, if the value of the first parameter is 3, the candidate values ​​of the second parameter include at least one of {14, 28, 56}; or, if the value of the first parameter is 5, the candidate values ​​of the second parameter include at least one of {56, 112, 224} symbols; or, if the value of the first parameter is 6, the candidate values ​​of the second parameter include at least one of {112, 224, 448} symbols. These values ​​are consistent with those in the current protocol. This design allows the second parameter value to be provided without changing the current protocol, which is beneficial for reliably providing the processing latency of the first CSI report. This gives the terminal device sufficient time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0215] Optionally, in one embodiment, if the value of the first parameter is 2 or 3, the candidate values ​​of the third parameter include at least one of the following symbols: {14, 28, 48, 224, 336}; or, if the value of the first parameter is 5, the candidate values ​​of the third parameter include at least one of the following symbols: {56, 112, 192, 896, 1344}; or, if the value of the first parameter is 6, the candidate values ​​of the third parameter include at least one of the following symbols: {112, 224, 384, 1792, 2688}.

[0216] In this embodiment of the application, if the value of the first parameter is 2 or 3, the candidate values ​​of the third parameter include at least one of the following symbols: {14, 28, 48, 224, 336}. That is, if μ in Table 3 is 2 or 3, then the candidate values ​​of KB (such as KB1, KB2, KB3, KB4) in Table 3 include at least one of the following symbols: {14, 28, 48, 224, 336}. If the value of the first parameter is 5, the candidate values ​​of the third parameter include at least one of the following symbols: {56, 112, 192, 896, 1344}. That is, if μ in Table 3 is 5, then the candidate values ​​of KB (such as KB1, KB2, KB3, KB4) in Table 3 include at least one of the following symbols: {56, 112, 192, 896, 1344}. If the value of the first parameter is 6, the candidate values ​​of the third parameter include at least one of the symbols {112, 224, 384, 1792, 2688}. That is, if μ in Table 3 above is 6, then the candidate values ​​of KB (such as KB1, KB2, KB3, KB4) in Table 3 above include at least one of the symbols {112, 224, 384, 1792, 2688}.

[0217] In other words, taking μ as 2 or 3 as an example, if μ in Table 3 above is 2 or 3, then the candidate values ​​of KB (such as KB1, KB2, KB3, KB4) in Table 3 include one or more of the symbols {14, 28, 48, 224, 336}. When the candidate values ​​of KB in Table 3 include one value from the symbols {14, 28, 48, 224, 336}, that one value can be, for example, {14}; when the candidate values ​​of KB in Table 3 include two values ​​from the symbols {14, 28, 48, 224, 336}, those two values ​​can be, for example, {14, 28}; when the candidate values ​​of KB in Table 3 include three values ​​from the symbols {14, 28, 48, 224, 336}... For example, these three values ​​could be {14, 28, 48}; when the candidate values ​​for KB in Table 3 include four values ​​from the symbols {14, 28, 48, 224, 336}, these four values ​​could be {14, 28, 48, 224}; when the candidate values ​​for KB in Table 3 include five values ​​from the symbols {14, 28, 48, 224, 336}, these five values ​​could be {14, 28, 48, 224, 336}. Other possible cases will not be detailed further.

[0218] In this embodiment, if the value of the first parameter is 2 or 3, the candidate values ​​of the third parameter include at least one of {14, 28, 48, 224, 336} symbols; or, if the value of the first parameter is 5, the candidate values ​​of the third parameter include at least one of {56, 112, 192, 896, 1344} symbols; or, if the value of the first parameter is 6, the candidate values ​​of the third parameter include at least one of {112, 224, 384, 1792, 2688} symbols. These values ​​are consistent with those in the current protocol. This design allows the third parameter value to be provided without changing the current protocol, which is beneficial for reliably providing the processing latency of the first CSI report. This gives the terminal device sufficient time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0219] It should be noted that if the value of the first parameter is 2, the candidate values ​​of the second parameter include at least one of the following 8, 14, and 28 symbols. This can be understood as, if the value of the first parameter is 2, the candidate values ​​of the second parameter include at least one of 8, 14, and 28 symbols. Other parameters are similar and will not be elaborated here.

[0220] Optionally, in one embodiment, the first value is Y2 times the third value, wherein if the value of the first parameter is 2, the third value is 44; or if the value of the first parameter is 3, the third value is 97; or if the value of the first parameter is 5, the third value is 388; or if the value of the first parameter is 6, the third value is 776.

[0221] Referring to Table 3 above, the third value in the embodiments of this application is a value in {44, 97, 388, 776}, and the third value is different for different values ​​of the first parameter.

[0222] Specifically, if the value of the first parameter is 2, that is, μ is 2 in Table 3 above and the third value is 44, then the first value is Y2*44; if the value of the first parameter is 3, that is, μ is 3 in Table 3 above and the third value is 97, then the first value is Y2*97; if the value of the first parameter is 5, that is, μ is 5 in Table 3 above and the third value is 388, then the first value is Y2*388; or, if the value of the first parameter is 6, that is, μ is 6 in Table 3 above and the third value is 776, then the first value is Y2*776.

[0223] In this embodiment, if the value of the first parameter is 2, the third value is 44; or, if the value of the first parameter is 3, the third value is 97; or, if the value of the first parameter is 5, the third value is 388; or, if the value of the first parameter is 6, the third value is 776. These values ​​are consistent with those in the current protocol. This design allows the third value to be provided without changing the current protocol, which is beneficial for reliably providing the processing latency of the first CSI report. This gives the terminal device sufficient time to process the first CSI report, thereby improving the performance of the terminal device's measurement reporting.

[0224] Optionally, in one embodiment, the value of Y is 2.

[0225] Optionally, in one embodiment, the number of CPUs reported by the first CSI is 1.

[0226] This application provides the number of CPUs in the first CSI report, that is, the number of CPUs in the first CSI report can be set to 1, which is consistent with the number of CPUs in the current second CSI report. This design can give the number of CPUs in the first CSI report without changing the current protocol, which is simple and reliable.

[0227] It should be understood that in some possible embodiments, the number of CPUs reported by the first CSI may also be other values, such as 2, 3, etc., without limitation.

[0228] The following section uses the first measurement resource, CSI-RS resource, to illustrate the specific interaction process between network devices and terminal devices.

[0229] Step 1: The network device configures R CSI report configurations to the terminal device via a first signaling. Each CSI report configuration corresponds to one CSI report. The R CSI reports include the first CSI report in method 500 above. The first CSI report is associated with a first measurement resource, which is continuous in the frequency domain and spans multiple non-contiguous SBFD DL subbands. Accordingly, the terminal device receives the first signaling.

[0230] Step 2: The network device triggers the terminal device to report S CSI reports on the PUSCH via the DCI carried by the PDCCH, and these S CSI reports include the first CSI report. Accordingly, the terminal device receives the DCI.

[0231] Step 3: The terminal device reports measurements based on the first signaling and DCI, and the measurement report reported by the terminal device includes the first CSI report.

[0232] Step 1 can be executed in the CU, DU, or RU. Specifically, within the CU, it can be executed in the CU-CP. The CU-CP is a logical node carrying the RRC layer and PDCP-C layer, used to implement the CU's control plane functions. In this technical solution, step 1 can be executed by the CU-CP to generate RRC signaling for configuring aperiodic CSI-RS measurement reports. The DU is a logical node carrying the RLC layer, MAC layer, Higher PHY, and other functions. In this technical solution, the DU can perform RLC layer, MAC layer, and Higher PHY layer processing on the RRC signaling generated in the CU-CP. The RU is a logical node carrying Lower PHY and RF processing. In this technical solution, the RU can further process the RRC signaling generated in the CU-CP using Lower PHY and RF processing, and then send the RRC signaling to the UE via the air interface.

[0233] Step 2 can be performed in both the DU and RU. In this technical solution, the DU can generate a DCI for triggering aperiodic CSI-RS measurement reports, which, after being processed by the RU, is sent to the UE via the air interface.

[0234] Step 3 can be performed in both the DU and RU. In this technical solution, the RU can receive the PUSCH carrying the aperiodic CSI-RS measurement report sent by the UE. The DU can process the received PUSCH to obtain the carried aperiodic CSI-RS measurement report.

[0235] Figure 8 is a schematic diagram of another communication method 800 provided in an embodiment of this application. The communication method 800 may include steps 810 to 840.

[0236] 810, Send the second information, which includes the configuration information of the first measurement report. The first measurement report is associated with the third measurement resource. The third measurement resource is continuous in the frequency domain and spans K1 SBFD DL subbands and K2 SBFD UL subbands, where K1 and K2 are both positive integers.

[0237] In this embodiment, the first measurement report is associated with a third measurement resource. The third measurement resource is continuous in the frequency domain and spans K1 SBFD DL sub-bands and K2 SBFD UL sub-bands. This can be understood as the third measurement resource falling within both K1 SBFD DL sub-bands and K2 SBFD UL sub-bands in the frequency domain. Alternatively, the third measurement resource can be understood as including a first part and a second part. The first part is located in the first SBFD DL sub-band in the frequency domain, and the second part is located in the first SBFD UL sub-band in the frequency domain. The first SBFD DL sub-band and the first SBFD UL sub-band are continuous. For details, please refer to Figure 9.

[0238] Referring to Figure 9, it can be seen that the third measurement resource is continuous in the frequency domain and spans two SBFD DL subbands and one SBFD UL subband. These two SBFD DL subbands are the DL1 subband and DL2 subband in Figure 9.

[0239] It should be noted that if the SBFD DL subband and the SBFD UL subband are not continuous, that is, there is a frequency gap between these two subbands, the terminal equipment can also perform measurements on the frequency resources of the gap.

[0240] 820, Receive the second message.

[0241] 830, based on the second information, a first measurement report is sent to the network device, the first measurement report being associated with a portion of the third measurement resource located in at least one SBFD DL subband in K1 SBFD DL subbands and / or at least one SBFD UL subband in K2 SBFD UL subbands.

[0242] In this embodiment, steps 820-830 can be executed by the terminal device, by a module of the terminal device (e.g., a chip, chip system, or processor), or by a logic node, logic module, or software capable of implementing all or part of the terminal device's functions. For ease of description, the terminal device will be used as an example throughout this document.

[0243] In this embodiment of the application, after the terminal device receives the second information from the network device, the second information includes the configuration information of the first measurement report. The first measurement report is associated with the third measurement resource, so that the terminal device can perform measurements based on the third measurement resource and send the measurement results to the network device, i.e., the aforementioned first measurement report.

[0244] During the measurement process based on the third measurement resource, the terminal device can perform measurements within different subbands. Correspondingly, the subband associated with the first measurement report will also be different. Specifically, if the terminal device performs measurements based on the third measurement resource within at least one SBFD DL subband of K1 SBFD DL subbands, then the first measurement report will be associated with a portion of the third measurement resource located within at least one SBFD DL subband of K1 SBFD DL subbands. If the terminal device performs measurements based on the third measurement resource within at least one SBFD UL subband of K2 SBFD UL subbands, then the first measurement report will be associated with a portion of the third measurement resource located within at least one SBFD UL subband of K2 SBFD UL subbands. If the terminal device performs measurements based on a third measurement resource in at least one SBFD DL subband of K1 SBFD DL subbands and at least one SBFD UL subband of K2 SBFD UL subbands, then the first measurement report associates the portion of the third measurement resource located in at least one SBFD DL subband of K1 SBFD DL subbands and at least one SBFD UL subband of K2 SBFD UL subbands.

[0245] 840, Received the first measurement report.

[0246] In this embodiment, steps 810 and 840 can be executed by a network device, a module of the network device (e.g., a chip, chip system, or processor), or a logical node, logical module, or software capable of implementing all or part of the functions of the network device. For ease of description, the following will consistently use a network device as an example.

[0247] In this embodiment, the network device can send second information, including configuration information of a first measurement report, to the terminal device. The first measurement report is associated with a third measurement resource. After receiving the second information from the network device, the terminal device can perform measurements based on the third measurement resource. Since the third measurement resource is continuous in the frequency domain and spans K1 SBFD DL subbands and K2 SBFD UL subbands, the terminal device can perform measurements and report them in any one of the SBFD DL subbands, SBFD UL subbands, or SBFD DL and SBFD UL subbands. This can improve the measurement performance and flexibility of the terminal device.

[0248] Optionally, in one embodiment, the first measurement report is associated with at least one of a first measurement method, a second measurement method, and a third measurement method. The first measurement method includes measurement within at least one SBFD DL sub-band among K1 SBFD DL sub-bands, the second measurement method includes measurement within at least one SBFD UL sub-band among K2 SBFD UL sub-bands, and the third measurement method includes measurement within at least one SBFD DL sub-band among K1 SBFD DL sub-bands and at least one SBFD UL sub-band among K2 SBFD UL sub-bands.

[0249] In the embodiments of this application, the first measurement report may be associated with at least one measurement method. For example, the first measurement report may be associated with one measurement method, such as the first measurement method; or, the first measurement report may be associated with two measurement methods, such as the first measurement method and the second measurement method; or, the first measurement report may be associated with three measurement methods, such as the first measurement method, the second measurement method, and the third measurement method.

[0250] The first measurement method includes measurement within at least one SBFD DL sub-band among K1 SBFD DL sub-bands. Specifically, the first measurement method can be understood as performing measurement based on a third measurement resource within at least one SBFD DL sub-band among K1 SBFD DL sub-bands. For example, if the third measurement resource includes two SBFD DL sub-bands, then the first measurement method is to perform measurement based on the third measurement resource within at least one SBFD DL sub-band among the two SBFD DL sub-bands. In other words, the terminal device can perform measurement based on the third measurement resource within one or more SBFD DL sub-bands among the two SBFD DL sub-bands.

[0251] The second measurement method involves measurement within at least one SBFD UL sub-band among the K2 SBFD UL sub-bands. In other words, the second measurement method can be understood as performing measurements based on a third measurement resource within at least one SBFD UL sub-band among the K2 SBFD UL sub-bands. For example, if the third measurement resource includes two SBFD UL sub-bands, then the second measurement method involves measurement within at least one SBFD UL sub-band among the two SBFD UL sub-bands. In other words, the terminal device can perform measurements based on the third measurement resource within one or more SBFD UL sub-bands among the two SBFD UL sub-bands.

[0252] The third measurement method includes measurement within at least one SBFD DL subband among K1 SBFD DL subbands and at least one SBFD UL subband among K2 SBFD UL subbands. That is, the third measurement method can be understood as performing measurements based on a third measurement resource within at least one SBFD DL subband among K1 SBFD DL subbands and at least one SBFD UL subband among K2 SBFD UL subbands. For example, if the third measurement resource includes two SBFD DL subbands and two SBFD UL subbands, then the third measurement method is to perform measurements within at least one SBFD DL subband among the two SBFD DL subbands and at least one SBFD UL subband among the two SBFD UL subbands. In other words, the terminal device can perform measurements based on the third measurement resource within one or more SBFD DL subbands among the two SBFD DL subbands and at least one SBFD UL subband among the two SBFD UL subbands.

[0253] In this embodiment, the first measurement report is associated with at least one of the three measurement methods. After receiving the first measurement report, the terminal device can perform measurements and report them in the corresponding sub-band based on the measurement method associated with the first measurement report. For example, if the first measurement report is associated with the first measurement method, the terminal device can perform measurements in at least one SBFD DL sub-band among K1 SBFD DL sub-bands. Alternatively, if the first measurement report is associated with the first measurement method and the second measurement method, the terminal device can perform measurements in at least one SBFD DL sub-band among K1 SBFD DL sub-bands, or in at least one SBFD UL sub-band among K2 SBFD UL sub-bands. Or, if the first measurement report is associated with the first measurement method, the second measurement method, and the third measurement method, the terminal device can perform measurements in at least one SBFD DL sub-band among K1 SBFD DL sub-bands, or in at least one SBFD UL sub-band among K2 SBFD UL sub-bands, or in at least one SBFD DL sub-band among K1 SBFD DL sub-bands and at least one SBFD UL sub-band among K2 SBFD UL sub-bands. Simultaneous measurement within the UL sub-band can improve the measurement performance and flexibility of the terminal equipment.

[0254] Optionally, in one embodiment, the first measurement report is associated with a first reporting method and / or a second reporting method, wherein the first reporting method corresponds to the first measurement report including a broadband measurement report, and the second reporting method corresponds to the first measurement report including multiple broadband measurement reports.

[0255] In the embodiments of this application, the first measurement report is associated with a first reporting method and / or a second reporting method. For example, the first measurement report may be associated with one reporting method, such as the first reporting method; or, the first measurement report may be associated with two reporting methods, such as the first reporting method and the second reporting method.

[0256] The first reporting method corresponds to a first measurement report including a broadband measurement report. That is, if the terminal device reports through the first reporting method, the terminal device sends a broadband measurement report to the network device. The broadband measurement report includes the measurement results of the terminal device based on the third measurement resources in one or more subbands.

[0257] The second reporting method corresponds to the first measurement report, which includes multiple broadband measurement reports. That is, if the terminal device reports through the second reporting method, the terminal device sends multiple broadband measurement reports to the network device. These multiple broadband measurement reports include the measurement results of the terminal device based on the third measurement resources in multiple subbands, and these multiple broadband measurement reports correspond one-to-one with multiple subbands.

[0258] In this embodiment, the first measurement report is associated with a first reporting method and / or a second reporting method. After receiving the first measurement report, the terminal device can report based on the reporting method associated with the first measurement report. For example, if the first measurement report is associated with the first reporting method, the terminal device can send a broadband measurement report to the network device. Alternatively, if the first measurement report is associated with the second reporting method, the terminal device can send multiple broadband measurement reports to the network device. Or, if the first measurement report is associated with the first reporting method and the second reporting method, the terminal device can send one or more broadband measurement reports to the network device, thereby improving the reporting performance and flexibility of the terminal device.

[0259] The preceding text introduced the measurement methods and reporting methods associated with the first measurement report. The following text will explain the relationship between the measurement methods and reporting methods in detail according to different situations.

[0260] Scenario 1:

[0261] In one embodiment, the first measurement method includes measurement within M SBFD DL subbands out of K1 SBFD DL subbands, where M is an integer less than or equal to K1. One broadband measurement report corresponds to M SBFD DL subbands; or, multiple broadband measurement reports include M broadband measurement reports, with each of the M broadband measurement reports corresponding one-to-one with one of the M SBFD DL subbands.

[0262] In this embodiment of the application, taking K1 as 2 as an example, and assuming M = 1, the terminal device can perform measurements based on the third measurement resource within one SBFD DL subband. The first measurement report can then include one broadband measurement report, which corresponds to this one SBFD DL subband. That is, the first measurement report includes the measurement results of the terminal device performing measurements based on the third measurement resource within this one SBFD DL subband, thus allowing the terminal device to report based on the first reporting method.

[0263] Taking K1 as 2 as an example, assuming M = 2, the terminal device can perform measurements based on the third measurement resource within two SBFD DL subbands (including SBFD DL1 and SBFD DL2 subbands). The first measurement report can then include one broadband measurement report or two broadband measurement reports. If the first measurement report includes one broadband measurement report, this report corresponds to the two SBFD DL subbands; that is, the first measurement report includes the measurement results of the terminal device performing measurements based on the third measurement resource within these two SBFD DL subbands. Therefore, the terminal device can report based on the first reporting method. If the first measurement report includes two broadband measurement reports, then these two broadband measurement reports correspond to these two SBFD DL subbands. Assuming that these two broadband measurement reports are broadband measurement report 1 and broadband measurement report 2, then broadband measurement report 1 can correspond to SBFD DL1 subband, and broadband measurement report 2 can correspond to SBFD DL2 subband. That is, these two broadband measurement reports respectively include the measurement results of the terminal device based on the third measurement resource in these two SBFD DL subbands, so that the terminal device can report based on the second reporting method.

[0264] In this embodiment, the first measurement method includes measurement within M SBFD DL subbands out of K1 SBFD DL subbands. For the first reporting method, the broadband measurement report included in the first measurement report corresponds to one of the M SBFD DL subbands. For the second reporting method, the multiple broadband measurement reports included in the first measurement report include M broadband measurement reports, and the M broadband measurement reports correspond one-to-one with the M SBFD DL subbands. That is, the terminal device can send broadband measurement reports of M SBFD DL subbands to the network device based on different reporting methods, thereby improving the reporting performance and flexibility of the terminal device.

[0265] Scenario 2:

[0266] In one embodiment, the second measurement method includes measurement within N SBFD UL subbands out of K2 SBFD UL subbands, where N is an integer less than or equal to K2. One broadband measurement report corresponds to N SBFD UL subbands; or, multiple broadband measurements include N broadband measurement reports, with each of the N broadband measurement reports corresponding one-to-one with one of the N SBFD UL subbands.

[0267] In this embodiment of the application, taking K2 as 2 as an example, and assuming N=1, the terminal device can perform measurements based on the third measurement resource within one SBFD UL subband. The first measurement report can then report one broadband measurement report, which corresponds to this one SBFD UL subband. That is, the first measurement report includes the measurement results of the terminal device performing measurements based on the third measurement resource within this one SBFD UL subband, thus allowing the terminal device to report based on the first reporting method.

[0268] Taking K2 as 2 as an example, assuming N=2, the terminal device can perform measurements based on the third measurement resource within two SBFD UL subbands (including SBFD UL1 and SBFD UL2 subbands). The first measurement report can then report one broadband measurement report or two broadband measurement reports. If the first measurement report includes one broadband measurement report, this report corresponds to the two SBFD UL subbands; that is, the first measurement report includes the measurement results of the terminal device performing measurements based on the third measurement resource within these two SBFD UL subbands. Therefore, the terminal device can report based on the first reporting method. If the first measurement report includes two broadband measurement reports, then these two broadband measurement reports correspond to these two SBFD UL subbands. Assuming that these two broadband measurement reports are broadband measurement report 1 and broadband measurement report 2, then broadband measurement report 1 can correspond to SBFD UL1 subband, and broadband measurement report 2 can correspond to SBFD UL2 subband. That is, these two broadband measurement reports respectively include the measurement results of the terminal device based on the third measurement resource in these two SBFD UL subbands, so that the terminal device can report based on the second reporting method.

[0269] In this embodiment, the second measurement method includes measurement within N SBFD UL subbands out of K2 SBFD UL subbands. For the first reporting method, the broadband measurement report included in the first measurement report corresponds to N SBFD UL subbands. For the second reporting method, the multiple broadband measurement reports included in the first measurement report include N broadband measurement reports, and the N broadband measurement reports correspond one-to-one with the N SBFD UL subbands. That is, the terminal device can send broadband measurement reports of N SBFD UL subbands to the network device based on different reporting methods, thereby improving the reporting performance and flexibility of the terminal device.

[0270] Scenario 3:

[0271] In one embodiment, the third measurement method includes measurements within P SBFD DL subbands out of K1 SBFD DL subbands and Q SBFD UL subbands out of K2 SBFD UL subbands, where P is an integer less than or equal to K1 and Q is an integer less than or equal to K2. One broadband measurement report corresponds to P SBFD DL subbands and Q SBFD UL subbands; or, multiple broadband measurement reports include (P+1) broadband measurement reports, where P broadband measurement reports among the (P+1) broadband measurement reports correspond one-to-one with P SBFD DL subbands, and the other broadband measurement report among the (P+1) broadband measurement reports corresponds to Q SBFD UL subbands; or, multiple broadband measurement reports include (Q+1) broadband measurement reports, where Q broadband measurement reports among the (Q+1) broadband measurement reports correspond one-to-one with Q SBFD UL subbands, and the other broadband measurement report among the (Q+1) broadband measurement reports corresponds to P SBFD DL subbands.

[0272] In this embodiment of the application, taking K1=K2=2 as an example, and assuming P=Q=1, the terminal device can perform measurements based on the third measurement resource within one SBFD DL subband and one SBFD UL subband. The first measurement report can then include one broadband measurement report or two broadband measurement reports. If the first measurement report is one broadband measurement report, this one broadband measurement report corresponds to the one SBFD DL subband and one SBFD UL subband, that is, the first measurement report includes the measurement results of the terminal device performing measurements based on the third measurement resource within the one SBFD DL subband and one SBFD UL subband, thereby allowing the terminal device to report based on the first reporting method. If the first measurement report contains two broadband measurement reports, then these two broadband measurement reports correspond to one SBFD DL subband and one SBFD UL subband. Assuming these two broadband measurement reports are Broadband Measurement Report 1 and Broadband Measurement Report 2, then Broadband Measurement Report 1 can correspond to the SBFD DL subband, and Broadband Measurement Report 2 can correspond to the SBFD UL subband. That is, these two broadband measurement reports respectively include the measurement results of the terminal device based on the third measurement resource in this one SBFD DL subband and one SBFD UL subband, so that the terminal device can report based on the second reporting method.

[0273] In this embodiment of the application, taking K1=K2=4 as an example, and assuming P=Q=2, the terminal device can perform measurements based on the third measurement resource within two SBFD DL subbands (including SBFD DL1 and SBFD DL2 subbands) and two SBFD UL subbands (including SBFD UL1 and SBFD UL2 subbands). The first measurement report can include one broadband measurement report or three broadband measurement reports. If the first measurement report is one broadband measurement report, this one broadband measurement report corresponds to the two SBFD DL subbands and two SBFD UL subbands. That is, the first measurement report includes the measurement results of the terminal device performing measurements based on the third measurement resource within these two SBFD DL subbands and two SBFD UL subbands, thus the terminal device can report based on the first reporting method. If the first measurement report is three broadband measurement reports, these three broadband measurement reports correspond to the two SBFD DL subbands and two SBFD UL subbands. There are two specific implementation methods for the broadband measurement report corresponding to the subband.

[0274] In one implementation, assuming the three broadband measurement reports are Broadband Measurement Report 1, Broadband Measurement Report 2, and Broadband Measurement Report 3, then Broadband Measurement Report 1 and Broadband Measurement Report 2 can each correspond to two SBFD DL subbands, and Broadband Measurement Report 3 can correspond to two SBFD UL subbands. For example, Broadband Measurement Report 1 corresponds to SBFD DL1 subband, Broadband Measurement Report 2 corresponds to SBFD DL2 subband, and Broadband Measurement Report 3 corresponds to SBFD UL1 and SBFD UL2 subbands. That is, two of the broadband measurement reports include the measurement results of the terminal device performing measurements based on the third measurement resource within these two SBFD DL subbands, and the other broadband measurement report includes the measurement results of the terminal device performing measurements based on the third measurement resource within these two SBFD UL subbands. Therefore, the terminal device can report based on the second reporting method.

[0275] In another implementation, assuming the three broadband measurement reports are Broadband Measurement Report 1, Broadband Measurement Report 2, and Broadband Measurement Report 3, then Broadband Measurement Report 1 can correspond to two SBFD DL subbands, and Broadband Measurement Report 2 and Broadband Measurement Report 3 can each correspond to two SBFD UL subbands. For example, Broadband Measurement Report 1 corresponds to SBFD DL1 and SBFD DL2 subbands, Broadband Measurement Report 2 corresponds to SBFD UL1 subband, and Broadband Measurement Report 3 corresponds to SBFD UL2 subband. That is, two of the broadband measurement reports include the measurement results of the terminal device performing measurements based on the third measurement resource within these two SBFD UL subbands, and the other broadband measurement report includes the measurement results of the terminal device performing measurements based on the third measurement resource within these two SBFD DL subbands. Therefore, the terminal device can report based on the second reporting method.

[0276] In this embodiment, the third measurement method includes measurements within P SBFD DL subbands out of K1 SBFD DL subbands and Q SBFD UL subbands out of K2 SBFD UL subbands. For the first reporting method, the first measurement report includes one broadband measurement report corresponding to P SBFD DL subbands and Q SBFD UL subbands. For the second reporting method, the first measurement report includes either (P+1) broadband measurement reports or (Q+1) broadband measurement reports. For the (P+1) broadband measurement reports, P broadband measurement reports correspond one-to-one with P SBFD DL subbands, and the remaining broadband measurement report corresponds to Q SBFD UL subbands; for the (Q+1) broadband measurement reports, Q broadband measurement reports correspond one-to-one with Q SBFD UL subbands, and the remaining broadband measurement report corresponds to P SBFD DL subbands. That is, the terminal device can send broadband measurement reports of P SBFD DL subbands and Q SBFD UL subbands to the network device based on different reporting methods, thereby improving the reporting performance and flexibility of the terminal device.

[0277] Optionally, in one embodiment, the communication method 800 further includes: a network device sending first indication information, the first indication information being used to indicate that a first measurement report is associated with one of a first measurement method, a second measurement method, and a third measurement method; and / or sending second indication information, the second indication information being used to indicate that the first measurement report is associated with a first reporting method or a second reporting method. Accordingly, a terminal device receives the first indication information and / or the second indication information.

[0278] In this embodiment, the network device can send first indication information to the terminal device. This first indication information is used to indicate that the first measurement report is associated with one of a first measurement method, a second measurement method, or a third measurement method. For example, the first indication information may indicate that the first measurement report is associated with the first measurement method, the second measurement method, or the third measurement method. When the first indication information indicates that the first measurement report is associated with the first measurement method, the terminal device can perform measurements within at least one of the K1 SBFD DL subbands and report the measurement results of that at least one SBFD DL subband to the network device.

[0279] The network device can send a second indication message to the terminal device. This second indication message is used to indicate whether the first measurement report is associated with a first reporting method or a second reporting method, such as the first measurement report being associated with the first reporting method. When the first indication message indicates that the first measurement report is associated with the first reporting method, the terminal device can send a broadband measurement report to the network device. This broadband measurement report includes the measurement results of the measurements performed by the terminal device in the corresponding subband according to the measurement method indicated by the first indication message.

[0280] It should be understood that in some possible implementations, the measurement method and reporting method associated with the first measurement report can also be indicated by an instruction message, without limitation.

[0281] Optionally, in one embodiment, the first indication information and / or the second indication information are carried on the second information; or, the first indication information and / or the second indication information are carried on the third information, the third information being used to trigger the measurement reporting corresponding to the first measurement report, wherein the measurement reporting is a CSI reporting or a semi-continuous CSI reporting.

[0282] In this embodiment of the application, the first indication information and / or the second indication information can be carried in the second information. In other words, the second information sent by the network device to the terminal device includes not only the configuration information of the first measurement report, but also the measurement method used by the terminal device for measurement and / or the reporting method used by the terminal device for reporting, which can save bit overhead.

[0283] Alternatively, the first indication information and / or the second indication information can be carried in the third information, which is used to trigger the measurement reporting corresponding to the first measurement report. In other words, the third information sent by the network device to the terminal device is used to trigger the measurement reporting corresponding to the first measurement report, and also includes the measurement method used by the terminal device for measurement and / or the reporting method used by the terminal device for reporting. This can save bit overhead.

[0284] The third information in the embodiments of this application can be DCI or MAC CE, etc., and is not limited thereto.

[0285] Optionally, in one embodiment, the first measurement report is an aperiodic CSI report, and the processing delay of the first measurement report includes a third delay and a fourth delay. The third delay is the minimum time interval between the last symbol of the PDCCH that triggers the first measurement report and the first symbol of the PUSCH that carries the first measurement report, and the fourth delay is the minimum time interval between the last symbol of the last measurement resource in the measurement resources associated with the first measurement report and the first symbol of the PUSCH that carries the first measurement report.

[0286] Optionally, in one embodiment, the third measurement resource is a CLI-RSSI resource, which is used to measure CLI-RSSI.

[0287] In this embodiment of the application, if the first measurement report is a non-periodic CSI report, the processing delay of the first measurement report may include a third delay and a fourth delay. The relevant content of the third delay can be referred to Z in Table 1 or Table 2 above, and the relevant content of the fourth delay can be referred to Z' in Table 1 or Table 2 above.

[0288] The following section uses CLI-RSSI resources as an example to illustrate the interaction process between network devices and terminal devices.

[0289] Step 1: The network device configures T CSI report configurations to the terminal device via a first signaling. Each CSI report configuration corresponds to one CSI report. The T CSI reports include the first measurement report from method 800 above. The first measurement report is associated with a third measurement resource, which is continuous in the frequency domain and spans K1 SBFD DL subbands and K2 SBFD UL subbands. Accordingly, the terminal device receives the first signaling.

[0290] Step 2: The terminal device reports measurements based on the first signaling and DCI, and the measurement report reported by the terminal device includes the first measurement report.

[0291] Step 1 can be executed in the CU, DU, or RU. Specifically, within the CU, it can be executed in the CU-CP. The CU-CP is a logical node carrying the RRC layer and PDCP-C layer, used to implement the CU's control plane functions. In this technical solution, step 1 can be executed by the CU-CP to generate RRC signaling for configuring aperiodic CLI-RSSI measurement reports. The DU is a logical node carrying the RLC layer, MAC layer, Higher PHY, and other functions. In this technical solution, the DU can perform RLC layer, MAC layer, and Higher PHY layer processing on the RRC signaling generated in the CU-CP. The RU is a logical node carrying Lower PHY and RF processing. In this technical solution, the RU can further process the RRC signaling generated in the CU-CP using Lower PHY and RF processing, and then send the RRC signaling to the UE via the air interface.

[0292] Step 2 can be performed in both the DU and RU. In this technical solution, the RU can receive the PUSCH sent by the UE carrying an aperiodic CLI-RSSI measurement report. The DU can process the received PUSCH to obtain the carried aperiodic CLI-RSSI measurement report.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
