Description

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on October 10, 2020, with application number 202011078491.3 and application name “A Method for Channel State Measurement”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to a method for measuring channel status and related equipment. Background Art

[0003] Discontinuous reception (DRX) is a mechanism that saves power consumption for terminals. The DRX mechanism allows the terminal to enter a sleep state at certain times. When the terminal is in the sleep state, it does not monitor the physical downlink control channel (PDCCH). When the terminal device needs to monitor the PDCCH, it wakes up from the sleep state. By shortening the time the terminal is in the non-sleep state, the power consumption of the terminal device is saved. After the terminal is configured with DRX, the terminal will monitor the PDCCH during the duration (on duration) of the DRX cycle. If the terminal detects a PDCCH that schedules new data, the terminal will start or restart the inactivity timer. During the running of the inactivity timer, the terminal will still monitor the PDCCH. Therefore, the time when the "on duration timer" and the "inactivity timer" are running is collectively referred to as the active time.

[0004] The terminal receives a channel state information reference signal (CSI-RS) within the activation time, obtains a channel state information (CSI) report based on the CSI-RS, and sends the CSI report to the network device. In the new radio (NR) Rel-16 standard, a secondary DRX mechanism is introduced, that is, the network device can configure two sets of DRX parameters for the terminal. One set of DRX parameters is used to constrain the behavior of the terminal on a first frequency domain resource (for example, a first frequency range (frequency range 1, FR1)), and the other set of DRX parameters is used to constrain the behavior of the terminal on a second frequency domain resource (for example, a second frequency range (frequency range 2, FR2)).

[0005] The current version of the standard only stipulates that when a terminal reports a CSI report, it can report channel state information when the terminal is within the activation time. Before the introduction of secondary DRX, since the terminal's behavior in FR1 and FR2 is constrained by the same set of DRX parameters, the activation times of FR1 and FR2 are aligned, and the terminal can report the channel state information of FR1 and FR2 together or not. However, with the introduction of the secondary DRX mechanism, the activation times corresponding to FR1 and FR2 may not be aligned. Therefore, when reporting a CSI report, the terminal may be within the activation time of FR1, but not within the activation time of the second frequency domain. In this case, how the terminal reports the CSI report has become an urgent problem that needs to be solved. Summary of the Invention

[0006] The embodiments of the present application provide a method for measuring channel status and related devices, which are used to solve the problem of how a terminal measures and reports the channel status when a network device configures two sets of DRX parameters for the terminal.

[0007] In the first aspect, an embodiment of the present application provides a method for measuring a channel state, which is applied to a terminal. First, the terminal sends a channel state information report within a first time unit, and then the terminal sends a channel state information report within a second time unit. The first time unit and the second time unit are adjacent time units for reporting channel state information reports. The first time unit is earlier than the second time unit. The first frequency domain resource corresponds to the first DRX parameter, and the second frequency domain resource corresponds to the second DRX parameter; the activation time of the second frequency domain resource is determined according to the second DRX parameter; in this embodiment, in the period between two consecutive channel state information reports, the terminal determines the channel state information report according to the situation of the CSI-RS resource on the second frequency domain resource. Whether it includes channel state information of the second frequency domain resource; wherein, in the first case, when there is a reference signal between the first time unit and the second time unit, and the reference signal is on the second frequency domain resource and is within the activation time of the second frequency domain resource, the channel state information report includes the channel state information of the second frequency domain resource; in the first case, when there is a reference signal between the first time unit and the second time unit, and the reference signal is on the second frequency domain resource and is within the activation time of the second frequency domain resource, the terminal needs to make a new measurement based on the reference signal, and the channel state information report includes the channel state information of the first frequency domain resource and the channel state information of the second frequency domain resource, so as to ensure that the network device obtains the new channel state information, thereby performing more accurate resource scheduling. In the second case, when there is a reference signal between the first time unit and the second time unit, the reference signal is on the second frequency domain resource and is not within the activation time of the second frequency domain resource; in the third case, when there is no reference signal between the first time unit and the second time unit, the channel state information report does not include the channel state information of the second frequency domain resource; in the second and third cases, the terminal can avoid repeatedly reporting the channel state information of the second frequency domain resource, avoid redundant information transmission, save uplink transmission resources, and improve the transmission performance of uplink transmission resources. In this embodiment, in the period between two consecutive CSI reports, the terminal determines whether the CSI report includes the channel state information of the second frequency domain resource based on the situation of the CSI-RS resource on the second frequency domain resource, and provides a method for the terminal to measure and report the channel state when the terminal is configured with two sets of DRX parameters.

[0008] In an optional implementation, the channel state information of the second frequency domain resource includes at least one of the following measurement items: CQI, PMI, LI, RI, CRI, SSBRI, L1-RSRP, and L1-SINR. In this embodiment, the method can be used for all measurement items or only for certain measurement items. The method in this embodiment can be applied to different scenarios, ensuring performance for different measurement items while maintaining flexibility.

[0009] In an optional implementation, the channel state information of the second frequency domain resource included in the second channel state information report is: the channel state information obtained based on the most recent measurement of the second frequency domain resource from the second time unit, thereby ensuring that the terminal reports the latest channel state information of the second frequency resource and enhancing the real-time performance of the network device in obtaining the channel state information.

[0010] On the second aspect, an embodiment of the present application provides a method for channel state measurement, which is applied to a terminal device. First, the terminal receives first configuration information sent by a network device, and the first configuration information is used to configure a first DRX parameter of a first frequency domain resource and a second DRX parameter of a second frequency domain resource. Then, the terminal sends a third channel state information report in a third time unit; in the first case, when the fourth channel state information report has been sent in a fourth time unit before the third time unit, and the fourth channel state information report has included the channel state information of the second frequency domain resource, the third channel state information report does not include the channel state information of the second frequency domain resource; in the first case, if the channel state information of the second frequency resource has been reported in the same DRX cycle, the channel state information of the second frequency resource will not be included in the CSI report reported this time, thereby avoiding the terminal from repeatedly reporting the channel state information of the second frequency resource, avoiding redundant information sending, saving uplink transmission resources, and improving the transmission performance of uplink transmission resources. In the second case, when the fourth channel state information report has been sent within the fourth time unit, and the fourth channel state information report does not include the channel state information of the second frequency domain resources, it means that the channel state information of the second frequency resource has not been reported before this report, then the CSI report reported this time will include the channel state information of the second frequency resource, thereby ensuring that the network device can obtain the channel state information for the second frequency resource, which is beneficial for the network device to perform scheduling and / or beam management, etc. In the third case, when the third time unit is the first time unit for reporting the channel state information report within the DRX cycle, the third channel state information report needs to include the channel state information of the second frequency domain resources. Thereby ensuring that the network device can obtain the channel state information for the second frequency domain resources, which is beneficial for the network device to perform scheduling and / or beam management, etc.

[0011] In a third aspect, an embodiment of the present application provides a method for channel state measurement, which is applied to a terminal device. First, the terminal receives first configuration information sent by a network device, where the first configuration information is used to configure a first DRX parameter for a first frequency domain resource and a second DRX parameter for a second frequency domain resource. Then, the terminal receives a reference signal in the second frequency domain resource, where the reference signal is within the activation time of the first frequency domain resource and outside the activation time of the second frequency domain resource. The activation time of the first frequency domain resource is determined based on the first DRX parameter, and the activation time of the second frequency domain resource is determined based on the second DRX parameter. It can be understood that in this embodiment, the "union" of the activation time of the first frequency domain resource and the activation time of the second frequency domain resource is used as the activation time of the second frequency domain resource. As long as the reference signal is within the "union", the terminal will receive and measure the reference signal. In this embodiment, an implementation method is provided for determining how to measure the reference signal when the reference signal resource is not within the activation time of the frequency domain resource.

[0012] In an optional implementation, further, the terminal sends a fifth channel state information report in the fifth time unit, and the fifth channel state information report includes the channel state information of the second frequency domain resource obtained according to the reference signal, and the reference signal is: a reference signal before the fifth time unit and closest to the fifth time unit. In this embodiment, the terminal measures the reference signal of the second frequency domain resource to obtain the channel measurement information of the second frequency domain resource. Although the reference signal is not within the activation time of the second frequency domain resource, it is still within the activation time of the first frequency domain resource. In this case, the terminal will still receive and measure the reference signal. At the same time, the fifth channel state information report reported in the fifth time unit includes the channel state information of the first frequency domain resource and the second frequency domain resource. In this embodiment, the terminal can report the latest channel state information, which enhances the real-time performance of the network device in obtaining channel state information, and facilitates the network device to perform scheduling and / or beam management.

In this embodiment, the CSI content contained in the channel state information report is indicated by the configuration information, that is, whether the channel state information report contains the channel state information of the second frequency domain resource is indicated by the configuration information. The network device has greater flexibility. The network device can determine the reporting behavior of the terminal through the second configuration information, thereby reducing the judgment steps of the terminal.

[0057] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. The term "and / or" as used herein can be a description of an association relationship between associated objects, indicating that three relationships can exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exists simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects are in an "or" relationship. The terms "first," "second," and so on in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules that are not explicitly listed or that are inherent to such process, method, product, or device.

[0058] In order to better understand this application, the terms involved in this application are first explained.

[0059] First, a note about DRX:

[0060] The network device can configure DRX for terminals in the connected state. Figure 1 As shown in the figure, in the time domain, time is divided into continuous DRX cycles. Each DRX cycle consists of an on duration and an opportunity for discontinuous reception (DRX). During the on duration, the terminal monitors the PDCCH. During the opportunity for DRX, the terminal does not monitor the PDCCH and is in a dormant state.

[0061] See also Figure 2 As shown, after the terminal is configured with DRX, the terminal starts an on-duration timer according to the DRX parameters configured by the network device (such as long cycle, offset). During the operation of the "on-duration timer", the terminal is in the on-duration period, and the terminal will monitor the PDCCH during the on-duration period within the DRX cycle. If the terminal detects a PDCCH used to schedule new data, the terminal will start an inactivity timer. During the operation of the "inactivity timer", the terminal will still monitor the PDCCH. The time when the on-duration timer and the inactivity timer are running can be collectively referred to as the active time. When the terminal is configured with carrier aggregation (CA), the behavior of the terminal in all cells will be subject to DRX control. The terminal behavior described here is such as "channel state information (CSI) measurement and reporting". All cells include primary cells and secondary cells, or all cells include only primary cells or secondary cells, wherein the primary cell is a cell used to maintain the connection between network equipment and terminals, and the secondary cell is a cell configured to increase the transmission rate or throughput.

[0062] Secondly, the following is an explanation of CSI measurement and reporting:

[0063] The network device sends a CSI-RS to the terminal. The CSI-RS is used by the terminal to measure the channel state. The terminal measures the CSI-RS to obtain a channel state information report (CSI report) and reports the CSI report to the network device. The network device can perform scheduling and / or beam management based on the CSI report reported by the terminal. The method in this application is applicable to periodic and semi-persistent CSI measurement and reporting.

[0064] Again, the CSI measurement and reporting instructions are performed in conjunction with the DRX terminal:

[0065] In the CA scenario, the network device configures CSI-RS resources for each cell. Different cells can be configured with different CSI-RS resources. The CSI-RS resources of each cell are independent of each other and have complementary effects. For periodic and semi-continuous CSI measurement and reporting, the terminal receives CSI-RS and sends CSI reports on multiple cells and within the activation time of DRX. In other words, if the CSI-RS is outside the activation time, the terminal may not receive and measure the CSI-RS. The network device will configure physical uplink control channel (PUCCH) (or physical uplink shared channel, PUSCH) resources for the terminal, and report the CSI report through PUCCH (or PUSCH) resources, where the PUCCH resources are pre-configured through RRC messages. PUSCH resources are scheduled through downlink control information (DCI). In the embodiment of the present application, PUCCH is used as an example of uplink transmission resources.

[0066] When the terminal needs to send a CSI report, it will send the most recently measured channel state information as the content of the CSI report to the network device. Figure 3AAs shown in the figure, the downward arrow represents the CSI-RS, and the upward arrow represents the physical uplink control channel (PUCCH) (or physical uplink shared channel (PUSCH)) that carries the CSI report. If CSI-RS 1 is within the activation period, the terminal receives and measures CSI-RS 1. If CSI-RS 2 is not within the activation period, the terminal does not receive CSI-RS 2. When the terminal needs to send a CSI report on the PUCCH, the content of the CSI report is measured based on CSI-RS 1, and the terminal does not measure CSI-RS 2.

[0067] Furthermore, if the PUCCH (or PUSCH) carrying the CSI report is outside the activation time, the terminal will not send the CSI report. Figure 3B As shown in the figure, since the PUCCH is not within the activation time, the terminal does not send a CSI report to the base station. In this case, although CSI-RS 1 is within the activation time (such as the on duration), the terminal may be able to determine in advance that it will not send a CSI report. If the terminal can determine in advance that it will not send a CSI report, it is not necessary to measure CSI-RS 1. If the terminal cannot determine in advance that it will not send a CSI report, it will usually measure CSI-RS 1 and obtain channel state information.

[0068] In addition, in CA scenarios, network equipment typically configures PUCCH resources in the primary cell (PCell). This means that the terminal receives and measures CSI-RS on multiple cells, but reports the channel state information of each cell to the network equipment through the PCell.

[0069] Finally, the content of the channel state information is explained.

[0070] Channel state information may include the following measurement items: channel quality indicator (CQI), precoding matrix indicator (PMI), CSI-RS resource indicator (CSI-RS resource indicator, CRI), synchronization signal block resource indicator (SSBRI), layer indicator (LI), rank indicator (RI), layer 1 reference signal receiving power (L1-RSRP), layer 1 signal to interference plus noise ratio (L1-SINR). Among them, CQI, PMI, LI and RI are usually used by base stations to schedule data transmission more efficiently. CRI, SSBRI, L1-RSRP and L1-SINR are usually used by base stations to obtain signal strength for beam management.

[0071] In NR Rel-15 and earlier standards, even in a CA scenario, when a terminal is configured with multiple cells, the terminal's behavior in each cell is constrained by the same set of DRX parameters, resulting in consistent behavior across all cells. However, in NR Rel-16, to further reduce terminal power consumption, the standard introduced a secondary DRX mechanism. This allows network equipment to configure two sets of DRX parameters for the same terminal.

[0072] Specific description of the two DRX mechanism configurations:

[0073] 1. Configuration of DRX parameters for frequency domain resources.

[0074] A network device can configure two sets of DRX parameters for a terminal. For example, the network device can send configuration information to the terminal, where the configuration information is used to configure a first DRX parameter for a first frequency domain resource and a second DRX parameter for a second frequency domain resource. The frequency domain resource can be a frequency range, and the first frequency domain resource can also be referred to as a first frequency range (frequency range 1, FR1). The second frequency domain resource can also be referred to as a second frequency range (frequency range 2, FR2). For example, FR1 corresponds to frequencies below 7.225 GHz, and FR2 corresponds to frequencies above 24.250 GHz.

[0075] The two sets of DRX parameters are completely different, or the first DRX parameters and the second DRX parameters are not completely the same. For example, some parameters in the two sets of DRX parameters are the same, and some parameters are different. DRX parameters include but are not limited to an onduration timer, an inactivity timer, a retransmission timer, a short cycle timer, a short cycle, and a long cycle. A long cycle is an integer multiple of a short cycle. For example, the long cycle is the same in the two sets of DRX parameters, but there is no restriction on which parameters are the same and which parameters are different in the other parameters. For example, the "onduration timer" of FR1 and FR2 is different, the "inactivity timer" of FR1 and FR2 is different, and the "short cycle timer" of FR1 and FR2 is different. However, the "retransmission timer" of FR1 and FR2 is the same, and the "long cycle" of FR1 and FR2 is the same.

[0076] The DRX parameters for FR1 and FR2 do not affect each other. For example, the onduration timer and inactivity timer can be configured separately for FR1 and FR2. The activation timer for FR2 can be shorter than that for FR1. Furthermore, the inactivity timer for FR1 and FR2 are triggered separately. That is, when a terminal receives a PDCCH in FR1, only the inactivity timer for FR1 is started (or restarted), without affecting the inactivity timer for FR2. Conversely, when a terminal receives a PDCCH in FR2, only the inactivity timer for FR2 is started (or restarted), without affecting the inactivity timer for FR1. For another example, a short cycle timer can be configured separately for FR1 and FR2. When the short cycle timer expires, the short cycle switches to a long cycle. Network devices can also send a media access control element (MAC CE) to control the transition between the "long cycle" and "short cycle" modes for FR1 (or FR2).

[0077] 2. Regarding the configuration of each cell on frequency domain resources.

[0078] In the CA scenario, the number of cells configured on FR1 and the number of cells configured on FR2 are not limited. For example, taking 4 cells as an example, 1 cell is configured on FR1, that is, 1 cell is within the frequency range corresponding to FR1. 3 cells are configured on FR2, that is, 3 cells are within the frequency range corresponding to FR2; or, 2 cells are configured on FR1 and 2 cells are configured on FR2. As for which frequency domain resource is configured on the primary cell and which frequency domain resource is configured on the secondary cell, there is no limit. For example, a primary cell (such as cell-1) and 1 secondary cell (such as cell-2) can be configured on FR1, and 2 secondary cells (such as cell-3 and cell-4) can be configured on FR2. Cell-1, cell-2, cell-3 and cell-4 are all service cells for the terminal.

[0079] FR1 corresponds to one set of DRX parameters (first DRX parameters), and FR2 corresponds to another set of DRX parameters (second DRX parameters). That is, all cells in FR1 are configured using the first DRX parameters, and all cells in FR2 are configured using the second DRX parameters. Cells in FR1 form a DRX group, or rather, the cells in FR1 belong to the same DRX group, a group of cells that use the first DRX parameters. Similarly, cells in FR2 also form a DRX group, or rather, the cells in FR2 belong to the same DRX group, a group of cells that use the second DRX parameters. The DRX group in FR1 includes cell-1 and cell-2, while the DRX group in FR2 includes cell-3 and cell-4. It can be understood that because the frequency in FR1 is lower than that in FR2, and the attenuation characteristic of electromagnetic waves is that the higher the frequency, the greater the attenuation. Therefore, the signal attenuation in FR1 is weaker than that in FR2, resulting in a larger coverage area for cells in FR1 than in FR2. Typically, the primary cell carries important signaling interactions (such as uplink control information (UCI)) and radio link management functions. To ensure a good connection between the terminal and the network device, the network device generally configures the primary cell in FR1 and configures the PUCCH in the primary cell. The terminal reports the CSI report to the network device through the primary cell to ensure CSI quality.

[0080] In conjunction with the description in point 1 above, the configuration of DRX parameters for FR1 can be understood as the configuration of the DRX group on FR1, and the configuration of DRX parameters for FR2 can be understood as the configuration of the DRX group on FR2. In this application, measurement of FR1 is equivalent to measurement of the DRX group on FR1 or measurement of cells in the DRX group of FR1, and measurement of FR2 is equivalent to measurement of the DRX group on FR2 or measurement of cells in the DRX group of FR2.

[0081] 3. Explanation on the misalignment between the activation time of FR1 and the activation time of FR2:

[0082] For example, since the on duration timer (and / or inactivity timer) of FR1 and FR2 are set to different durations, and the "inactivity timer" of the two FRs is triggered and processed separately, the "inactivity timers" of the two FRs do not affect each other, so the activation time of FR1 and FR2 is likely to be misaligned. Figure 4 and Figure 5 As shown in the figure, the "on duration" of FR1 and FR2 is different in length, and the terminal receives PDCCH in FR1, so the "inactivity timer" in FR1 starts running, while the terminal does not receive PDCCH in FR2, so the "inactivity timer" is not started in FR2, resulting in the misalignment of the "active time" in FR1 and FR2.

[0083] exist Figure 4 In the example including only “long cycle” shown in FIG, “misalignment” of activation time may mean that the start time unit of activation time of FR1 and FR2 is the same, but the end time unit of activation time is different.

[0084] Another example is when one of FR1 and FR2 is started in a "short cycle". Figure 5 As shown, the DRX cycle of FR2 includes a short cycle. The "misalignment" of the activation time can mean that: the starting time unit of the activation time of FR1 and FR2 is the same, but the ending time unit of the activation time is different; or, the starting time unit of the activation time of FR1 and FR2 is different, and the ending time unit of the activation time is also different; or, the starting time unit of the activation time of FR1 and FR2 is different, but the ending time unit of the activation time is the same.

[0085] It should be noted that, for the sake of convenience, Figure 4 Only one "long cycle" is shown, and no "short cycle" is shown. This is mainly to illustrate that due to the existence of two sets of DRX parameters, the activation times of FR1 and FR2 may not be aligned, and whether the DRX cycle includes a "short cycle" is not limited.

[0086] The current standard stipulates that a terminal should only report CSI reports when the PUCCH (or PUSCH) carrying the CSI report falls within the activation period. The current standard does not specify how the terminal should measure and report channel state information for DRX groups without PUCCH resources when the network equipment configures two sets of DRX parameters for the terminal, each corresponding to different frequency resources.

[0087] An embodiment of the present application provides a method for measuring a channel state, which is used to solve the problem of how a terminal measures and reports a channel state when a network device configures two sets of DRX parameters for the terminal.

[0088] The method is applied to a communication system, including but not limited to a fourth generation (4G) communication system, a 5G communication system, a 6G communication system, a system integrating multiple communication systems, or a future evolved communication system, such as a long term evolution (LTE) system, a NR system, and a communication system related to the third generation partnership project (3GPP), as well as other such communication systems.

[0089] See also Figure 6A As shown, the communication system includes a network device 60 and a terminal 61, which are in communication connection with each other. The network device 60 configures two sets of DRX parameters for the terminal 61. The network device 60 sends a CSI-RS to the terminal 61. The CSI-RS is used to trigger the terminal 61 to perform channel state measurement. The terminal 61 performs measurement based on the CSI-RS to obtain a CSI report and reports the CSI report to the network device 60.

[0090] In the present application, network equipment includes but is not limited to: evolved base stations (NodeB or eNB or e-NodeB, evolutionary Node B) in LTE, base stations (gNodeB or gNB) or transmission receiving points (transmission receiving point / transmission reception point, TRP) in NR, base stations of subsequent evolution of 3GPP, wireless relay nodes, wireless backhaul nodes, etc. The base station can be: a macro base station, a micro base station, a relay station, etc. Multiple base stations can support the network of the same technology mentioned above, or they can support the network of different technologies mentioned above. The base station may include one or more co-sited or non-co-sited TRPs. The network device can also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. In the embodiment of the present application, the network device takes a base station as an example.

[0091] In one example, the network device is a base station including a radio frequency unit, a baseband processing unit, and a central processing unit with scheduling processing functions. In a CA scenario, the terminal is connected to one base station. The base station can cover multiple cells.

[0092] In another example, see Figure 6B As shown, the communication system may also include multiple network devices and terminals, where the multiple network devices include a first network device 601 and a second network device 602. The first network device 601 and the second network device 602 may be connected to each other in some manner to coordinate scheduling, allowing multiple cells to coordinate operation in a CA manner. In a CA scenario, the first network device 601 and the second network device 602 are in communication connection, with the first network device 601 performing resource scheduling. The terminal 61 may be in communication connection with multiple network devices, which may cover multiple serving cells.

[0093] In the present application, the terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a terminal in industrial control, a vehicle-mounted terminal device, a terminal in self-driving, a terminal in assisted driving, a terminal in remote medical, a terminal in smart grid, a terminal in transportation safety, a terminal in smart city, a terminal in smart home, etc. The embodiments of the present application do not limit the application scenarios. The terminal can sometimes also be referred to as a terminal device, user equipment (UE), UE unit, UE station, mobile station, mobile station, remote station, remote terminal device, mobile device, UE terminal device, wireless communication device, machine terminal, UE agent or UE device, etc. In the embodiments of the present application, the terminal can be taken as an example of a mobile phone.

[0094] In this application, uplink transmission resources (PUCCH or PUSCH) are configured or indicated on FR1, and the terminal reports CSI to the network device through the PUCCH or PUSCH on FR1. The PUCCH or PUSCH is within the activation time of FR1, and the activation time of FR1 is longer than the activation time of FR2. Since the PUCCH or PUSCH is within the activation time of FR1, the CSI report reported by the terminal will at least include the channel state information of FR1. In the embodiments of this application, more attention is paid to how to report the channel state information of FR2. A method for measuring channel state provided in this application is described below through specific embodiments.

[0095] It should be noted that the "activation time of FR1" described in the embodiment of the present application means: the network device configures the first DRX parameter for FR1, the DRX group using the first DRX parameter is located on FR1, and according to the DRX mechanism, the terminal is in active time on FR1. That is, in the present application, the meaning of "activation time of FR1" is the time when the terminal is in active time on FR1. Similarly, the activation time of "FR2" means: the network device configures the second DRX parameter for FR2, the DRX group using the second DRX parameter is located on FR2, and according to the DRX mechanism, the terminal is in active time on FR2. That is, in the present application, the meaning of "activation time of FR2" is the time when the terminal is in active time on FR2.

[0096] Example 1

[0097] In this embodiment, during a period between two consecutive CSI reports, the terminal determines whether the CSI report includes the channel state information of FR2 according to the conditions of the CSI-RS resources on FR2.

[0098] See also Figure 7 As shown, an embodiment of a channel state measurement method provided by the present application includes:

[0099] Step 701: A network device sends first configuration information to a terminal. Accordingly, the terminal receives the first configuration information sent by the network device. The first configuration information is used to configure a first DRX parameter for a first frequency domain resource and a second DRX parameter for a second frequency domain resource.

[0100] The first configuration information may be carried in a radio resource control (RRC) message. For example, an RRC Connection Setup message; or an RRC Connection Reconfiguration message; or an RRC Connection Reestablishment message. Specifically, the first configuration information may be MAC-CellGroupConfig (including drx-Config and drx-ConfigSecondaryGroup), where drx-Config is used to configure the first DRX parameters and drx-ConfigSecondaryGroup is used to configure the second DRX parameters.

[0101] In this embodiment of the present application, the DRX parameters "on duration timer," "inactivity timer," and "long cycle" are used as examples for explanation. The "long cycle" of FR1 is the same as the "long cycle" of FR2. The terminal can determine the activation time of FR1 based on the "on duration timer" and "inactivity timer" of FR1, and determine the activation time of FR2 based on the "on duration timer" and "inactivity timer" of FR2. In this embodiment of the present application, the example of the activation time of FR1 being longer than the activation time of FR2 is used for explanation.

[0102] It can be understood that, when a network device configures a first DRX parameter for a first frequency resource, it is equivalent to configuring the first DRX parameter for one or more first cells using the first frequency resource, and the one or more first cells are a first DRX group. Configuring a second DRX parameter for a second frequency resource is equivalent to configuring the second DRX parameter for one or more second cells using the second frequency resource, and the one or more second cells are a second DRX group.

[0103] In the embodiment of the present application, for the sake of simplicity of description, the measurement of FR1 herein is the measurement of the first DRX group, which will not be described in detail below, and the measurement of FR2 is the measurement of the second DRX group, which will not be described in detail below.

[0104] Step 702: The terminal sends a first channel state information report within a first time unit. Correspondingly, the network device receives the first channel state information report within the first time unit.

[0105] See also Figure 8A and Figure 8B As shown, the DRX group on FR1 is configured with the first DRX parameter, and the DRX group on FR2 is configured with the second DRX parameter. CSI-RS resources are configured in both DRX groups (in Figure 8A and 8B (indicated by a downward arrow in 8A and 8B), the PUCCH resources (indicated by an upward arrow in 8A and 8B) are configured on the PCell of FR1. There are CSI-RS resources in the "onduration" of FR1 and in the "on duration" of FR2. In this application, in order to distinguish CSI-RS, the CSI-RS of the first frequency domain resources is recorded as "FR1 CSI-RS", and the CSI-RS of the second frequency domain resources is recorded as "FR2 CSI-RS". At the same time, in order to distinguish different CSI-RS on the first frequency domain resources, the different CSI-RS on the first frequency domain resources are recorded as "FR1CSI-RS1" and "FR1 CSI-RS2". Similarly, the different CSI-RS on the second frequency domain resources are recorded as "FR2 CSI-RS1" and "FR2 CSI-RS2". It will not be repeated below.

[0106] There is a "FR1 CSI-RS1" resource within the "on duration" of FR1, and there is a "FR2 CSI-RS 1" resource within the "on duration" of FR2. Before the first time unit, the first reference signal of FR1 (FR1 CSI-RS 1) and the first reference signal of FR2 (FR2 CSI-RS 1) are in the activation time. Therefore, the terminal will receive and measure the first reference signal of FR1 (FR1 CSI-RS 1) and the first reference signal of FR2 (FR2 CSI-RS 1), thereby obtaining the channel state information of FR1 and the channel state information of FR2. PUCCH1 is within the activation time (active time) of FR1, and the terminal sends a first channel state information report through the first uplink resource (such as PUCCH1) within the first time unit. The first channel state information report includes the channel state information of FR1 and the channel state information of FR2.

[0107] Step 703: The terminal sends a second channel state information report within the second time unit. Correspondingly, the network device receives the second channel state information report within the second time unit.

[0108] The terminal sends a second channel state information report via a second uplink resource (such as PUCCH2) in a second time unit, such as Figure 8A and Figure 8B As shown, when the terminal receives PDCCH within the "on duration" of FR1, the terminal starts the "inactivity timer". The running time of the "inactivity timer" is as follows Figure 8A and Figure 8B As shown by the "shading", PUCCH2 is within the "inactivity timer" running time, and PUCCH2 is within the activation time (active time) of FR1. The first time unit and the second time unit are time units for reporting two adjacent (or consecutive) channel state information reports, and the first time unit is earlier than the second time unit. For example, in the same DRX cycle, the first time unit is the time unit for reporting the first CSI report, and the second time unit is the time unit for reporting the second CSI report. The terminal has not performed any reporting behavior between the first time unit and the second time unit. In this example, it is sufficient to ensure that the first time unit and the second time unit are the time units for reporting two adjacent channel state information reports, and it is not limited to which time unit the first time unit is reported.

[0109] In this example, the CSI-RS resources on FR2 are comprehensively considered during the period of two consecutive CSI reports to determine whether the CSI report reported this time includes the channel state information of FR2. Figure 8A As shown, for FR1, during the period between two consecutive CSI reports by the terminal, if there is a "FR1 CSI-RS2" resource and the "FR1 CSI-RS2" resource is within the activation time of FR1, the terminal measures "FR1 CSI-RS2" to obtain the channel state information of FR1. For FR2, if there is a "FR2 CSI-RS2" resource and the "FR2 CSI-RS2" is within the activation time of FR2, the terminal measures "FR1 CSI-RS2" to obtain the channel state information of FR2. In the first case, when there is a reference signal (CSI-RS) between the first time unit and the second time unit, and the reference signal (FR2 CSI-RS2) is on the second frequency domain resource and within the activation time of the second frequency domain resource, the terminal needs to perform a new measurement based on FR2 CSI-RS2. The second channel state information report includes the channel state information of FR1 and FR2. Therefore, the new channel state information of FR1 and FR2 is reported in the second time unit, ensuring that the network device obtains the new channel state information, thereby performing more accurate resource scheduling.

[0110] Between the first time unit and the second time unit, for FR2, if the terminal has not performed any new measurement, the terminal will not report the channel state information of FR2, such as the second and third cases described below.

[0111] Second case: Please refer to Figure 8B As shown in the figure, for FR1, between the first time unit and the second time unit, when there is "FR1 CSI-RS2" and "FR1 CSI-RS2" is within the activation time, the terminal measures "FR1 CSI-RS2" to obtain the channel state information of FR1. For FR2, when there is "FR2 CSI-RS2" resource but "FR2 CSI-RS2" is outside the activation time (i.e., not within the activation time), the CSI report reported by the terminal includes the channel state information of FR1, but does not include the channel state information of FR2.

[0112] The third case: please refer to Figure 8CAs shown, when there is no FR2 reference signal (FR2 CSI-RS2) within the time period between two adjacent (consecutive) CSI reports, that is, the terminal has not performed any new measurements on FR2 between the first time unit and the second time unit, the second channel state information report only includes the channel state information for FR1 and does not include the channel state information for FR2. In the third case, the channel state information for FR2 has already been reported in the first time unit. When the terminal has not performed any new measurements on FR2, the CSI report reported by the terminal does not include the channel state information for FR2. In this embodiment, in the second and third cases, since the terminal has not performed any new measurements on FR2, there is no need to report the channel state information for FR2. Because even if the channel state information for FR2 is reported, the channel state information measured based on FR2 CSI-RS1 is reported again. Therefore, in the second and third cases, the terminal does not report the channel state information for FR2. This avoids the terminal from repeatedly reporting the channel state information for FR2, avoids redundant information transmission, saves uplink transmission resources, and improves the transmission performance of uplink transmission resources.

[0113] Optionally, the channel state information measurement items in the CSI report in this embodiment may include at least one of the following: CQI, PMI, LI, RI, CRI, SSBRI, L1-RSRP, and L1-SINR. The method of this embodiment can be used for all measurement items or only for certain measurement items. The terminal reports the CSI report to the network device, and the network device performs scheduling adjustments and / or beam management and other related tasks based on the reported content.

[0114] Optionally, see Figure 8D As shown, within the same DRX cycle, between the first time unit and the second time unit, there are one or more CSI-RS resources in FR2, such as multiple CSI-RS resources including FR2 CSI-RS2 resources and FR2CSI-RS3 resources, and both FR2 CSI-RS2 resources and FR2 CSI-RS3 resources are in the activation time. Among them, the time domain position of FR2 CSI-RS2 is located before the time domain position of FR2 CSI-RS3. The terminal measures FR2 CSI-RS2 and FR2CSI-RS3 to obtain channel state information, but the channel state information of the second frequency domain resource included in the CSI report reported by the terminal is: the channel state information obtained based on the most recent measurement of the second frequency domain resource from the second time unit (that is, the channel state information obtained based on the measurement of FR2 CSI-RS3). This ensures that the terminal reports the latest channel state information of FR2, and enhances the real-time performance of the network device in obtaining channel state information.

[0115] It is understandable that in this application, the PUCCH may be within the activation time of FR1, but not within the activation time of FR2. For example, the on duration of FR1 and the on duration of FR2 are different in length, resulting in misalignment of the activation time of FR1 and FR2. Alternatively, the terminal receives a PDCCH in FR1, and the corresponding "inactivity timer" of FR1 starts running, but the terminal does not receive a PDCCH in FR2. Therefore, the "inactivity timer" will not be started in FR2, resulting in misalignment of the "active time" of FR1 and FR2.

[0116] In the case where the activation times of FR1 and FR2 are not aligned, the PUCCH may be located within the activation time of FR1 but not within the activation time of FR2. Alternatively, the CSI-RS resources may be located within the activation time of one FR (such as FR1) but not within the activation time of another FR (such as FR2). When the activation times of FR1 and FR2 are not aligned, the embodiments of the present application address how a terminal can measure and report channel state information in a DRX group without PUCCH resources.

[0117] For example, see Figure 9 As shown, the terminal determines whether to report the channel state information of FR2 according to the CSI-RS resource situation on FR2, which may include the following steps:

[0118] S11. Determine whether the second time unit is within the activation time of the second frequency domain resource. If the second time unit is outside the activation time of the second frequency domain resource, execute step S12. If the second time unit is within the activation time of the second frequency domain resource, execute step S14.

[0119] The second time unit is the time unit for reporting the CSI report and is pre-configured by the network device through an RRC message. The terminal can determine the activation time of FR2 based on the second DRX parameter (such as "on duration timer" or "inactivity timer"). Furthermore, the terminal can determine whether the second time unit falls outside the activation time of the second frequency domain resource.

[0120] S12. Determine whether there is a FR2 reference signal (FR2 CSI-RS2) resource between the first time unit and the second time unit. If it is determined that there is a "FR2 CSI-RS 2" resource between the first time unit and the second time unit, execute step S13; if it is determined that there is no "FR2 CSI-RS 2" resource between the first time unit and the second time unit, execute step S15.

[0121] The terminal may pre-receive first indication information sent by a network device, where the first indication information is used to indicate a CSI-RS resource set for FR2 (or the first indication information is used to indicate CSI-RS resource sets for FR1 and FR2). The CSI-RS resource set may include at least one CSI-RS resource, and the time domain position of the "FR2 CSI-RS" in the CSI-RS resource set may be determined based on the first indication information. Then, it is determined whether there are CSI-RS resources for FR2 falling within the time period between the first time unit and the second time unit. If there are CSI-RS resources for FR2 (such as FR2 CSI-RS2) in the CSI-RS resource set located between the first time unit and the second time unit, it is determined that there are second reference signal resources for FR2 between the first time unit and the second time unit.

[0122] S13. When the FR2 CSI-RS 2 resource exists between the first time unit and the second time unit, continue to determine whether the FR2 reference signal FR2 CSI-RS 2 is within the activation period. If FR2 CSI-RS 2 is within the activation period, execute step S14; if FR2 CSI-RS 2 is outside the activation period, execute step S15.

[0123] The activation time of FR2 may be determined according to the second DRX parameter, and the time domain position of FR2 CSI-RS2 may be determined in step S12, and then it is further determined whether "FR2 CSI-RS2" is within the activation time.

[0124] S14. When "FR2 CSI-RS2" is within the activation time, the terminal needs to measure FR2 CSI-RS2 to obtain channel state information of FR2. The second channel state information report includes channel state information (CSI) of FR1 and FR2.

[0125] S15. When "FR2 CSI-RS2" is not within the activation time, the second channel state information report includes the channel state information of FR1 but does not include the channel state information of FR2.

[0126] above Figure 9 The corresponding examples are merely illustrative descriptions for ease of understanding and do not constitute a limitation to the present application. For example, S11, S12, and S13 may also be performed in one step; or, S11 and S12 may be performed in one step; or, S12 and S13 may be performed in one step, etc.

[0127] It will be appreciated that in this embodiment, when a network device receives a CSI report reported by a terminal, it also needs to determine the CSI content contained in the CSI report, such as whether the CSI report contains only channel state information for FR1 or for both FR1 and FR2. The network device must correctly determine the content contained in the CSI report before it can correctly parse the CSI report using the corresponding method. The network device and the terminal maintain the same judgment rules, namely, the network device also determines whether the CSI report contains channel state information for FR2 based on the three aforementioned situations, which will not be further described here.

[0128] Example 2

[0129] See also Figure 10 As shown, an embodiment of the present application provides another embodiment of a method for channel state measurement. In this embodiment, when a terminal reports a CSI report in the current DRX cycle, it confirms whether a report has been made for FR2. If FR2 channel state information has been reported in the current DRX cycle, the current CSI report does not include FR2 channel state information. Otherwise, the CSI report currently to be reported must include FR2 channel state information.

[0130] Step 1001: A network device sends first configuration information to a terminal. Correspondingly, the terminal receives the first configuration information sent by the network device. The first configuration information is used to configure a first DRX parameter for a first frequency domain resource and a second DRX parameter for a second frequency domain resource.

[0131] This step refers to Figure 7 The description of step 701 in the corresponding embodiment is not repeated here.

[0132] Step 1002: The terminal sends a third channel state information report in a third time unit. Correspondingly, the network device receives the third channel state information report in the third time unit.

[0133] The third time unit is within the activation time unit of FR1 and outside the activation time of FR2, and the terminal determines the activation time of the second frequency domain resource according to the second DRX parameter. The terminal determines the activation time of the first frequency domain resource according to the first DRX parameter.

[0134] The CSI content in the third channel information report (CSI report) may include the following situations:

[0135] First case: Please refer to Figure 11AAs shown, within the same DRX cycle, when a fourth channel state information report has been sent via a fourth uplink resource (such as PUCCH4) within a fourth time unit, and the fourth channel state information report includes FR2 channel state information (such as channel state information measured based on FR2 CSI-RS1), when the terminal sends a third channel state information report via a third uplink resource (such as PUCCH3) within a third time unit, the third channel state information report only includes FR1 channel state information, and does not include FR2 channel state information. The fourth time unit is earlier than the third time unit. In the first case, if FR2 channel state information has already been reported within the same DRX cycle, the CSI report reported this time does not include FR2 channel state information, thereby avoiding the terminal from repeatedly reporting FR2 channel state information, avoiding redundant information transmission, saving uplink transmission resources, and improving the transmission performance of uplink transmission resources.

[0136] Second case: when the fourth channel state information report has been sent within the fourth time unit and the fourth channel state information report does not include the channel state information of the second frequency domain resource, the third channel state information report includes the channel state information of FR2. Figure 11B As shown in the example, before the fourth time unit, FR1 CSI-RS1 is received and measured on FR1, but there are no FR2 CSI-RS resources. In this case, the fourth channel state information report only includes FR1 channel state information and does not include FR2 channel state information. That is, no channel state information for FR2 has been reported in the current DRX cycle. However, before the fourth time unit and the third time unit, the terminal receives and measures FR2 CSI-RS1, obtaining FR2 channel state information. Therefore, the currently reported CSI report must include FR2 channel state information (e.g., channel state information measured based on FR2 CSI-RS1). In this embodiment, within the same DRX cycle, if FR2 channel state information has not been reported before the current report, the currently reported CSI report includes FR2 channel state information. This ensures that the network device can obtain FR2 channel state information at least once within a DRX cycle, which facilitates scheduling and beam management.

[0137] The third case: when the third time unit is the first time unit for reporting a channel state information report in the DRX cycle, the third channel state information report includes the channel state information of the second frequency domain resources.

[0138] See also Figure 11CAs shown, before the third time unit, when FR1 CSI-RS1 is within the activation time of FR1 and FR2 CSI-RS1 is within the activation time of FR2, the terminal receives and measures FR1 CSI-RS1 and FR2 CSI-RS1 to obtain channel state information for FR1 and FR2. In this third case, when the third time unit is the time unit for reporting the first CSI report in this DRX cycle, the third channel state information report includes the channel state information for FR1 and FR2. This ensures that the network device can obtain the channel state information for FR2, which is beneficial for the network device to perform scheduling and beam management.

[0139] In this embodiment, compared with the provisions of the existing standards, the UE will report CSI only when the PUCCH (or PUSCH) is within the activation time. As a result, when the PUCCH (or PUSCH) is outside the activation time of FR2, the terminal will not report the channel state information of FR2. Please refer to Figure 11C As shown, when the PUCCH3 (or PUSCH) resource is not within the onduration of FR2, the CSI report does not include channel measurement information for FR2. If no scheduling information (i.e., PDCCH) is received on FR2, the "inactivity timer" will not be started on FR2. Then, the PUCCH resource will not be within the activation time of FR2. At this time, in order to obtain the channel state information of FR2, the network device will deliberately configure the onduration timer of FR2 to be longer, so that the PUCCH resource can be within the onduration of FR2. This will restrict the configuration of the network device. Alternatively, in order to obtain the channel state information of FR2, the network device will specifically send a scheduling information to schedule an empty packet, thereby starting the inactivity timer of FR2 and extending the activation time of FR2 so that the PUCCH resource can be within the onduration of FR2. This will result in unnecessary resource waste. Extending the activation time of FR2 will also increase the power consumption of the terminal in FR2. However, through the method in the embodiment of the present application, the length of the onduration timer of FR2 can be arbitrarily configured, thereby reducing the configuration restrictions on the network device.

[0140] For example, see Figure 12 As shown, in the current DRX cycle, before reporting the CSI report, the terminal determines whether to report the FR2 channel state information according to the reported FR2 channel state information, which may include the following steps:

[0141] S21: Determine whether the third time unit is within the activation time of FR2. If the third time unit is outside the activation time of FR2, execute step S22. If the third time unit is within the activation time of FR2, directly execute step S25.

[0142] S22. Determine whether a CSI report has been reported before the third time unit. If a CSI report has been reported before the third time unit (i.e., the third time unit is not the first reported time unit), execute step S23. If no CSI report has been reported before the third time unit (i.e., the third time unit is the first reported time unit), directly execute step S25.

[0143] S23. When the terminal determines that a CSI report has been reported before the third time unit (the fourth time unit), the terminal continues to determine whether the CSI report reported via PUCCH4 in the fourth time unit includes channel state information for FR2. If it is determined that the CSI report reported in the fourth time unit includes channel state information for FR2 (i.e., channel state information has been reported for FR2), step S24 is executed; if it is determined that the CSI report reported in the fourth time unit does not include channel state information for FR2, step S25 is executed.

[0144] S24. The CSI report reported in the third time unit (this time) does not include the channel state information of FR2.

[0145] S25. The CSI report reported in the third time unit (this time) includes the channel state information of FR2.

[0146] above Figure 12 The corresponding examples are merely exemplary illustrations for ease of understanding and do not limit the present application. For example, S21 and S22 may also be performed in one step.

[0147] Optionally, the channel state information measurement items in the CSI report in this embodiment may include at least one of the following: CQI, PMI, LI, RI, CRI, SSBRI, L1-RSRP, and L1-SINR. The method of this embodiment can be used for all measurement items or only for certain measurement items. The terminal reports CSI to the network device, and the network device performs scheduling adjustments and / or beam management-related tasks based on the reported content. For example, this embodiment may include measurement items for beam management, such as CRI, SSBRI, L1-RSRP, and L1-SINR. In order for the base station to select a beam suitable for communication with the terminal, a CSI report needs to be reported at least once per DRX cycle. According to the method in this embodiment, if the terminal determines that CSI has never been reported for FR2 in the current DRX cycle, it needs to report the channel state information for FR2 to the network device. If the terminal determines that CSI has already been reported for FR2 in the current DRX cycle, it may not report the channel state information for FR2 to reduce redundant information reported.

[0148] Optionally, within the same DRX cycle, before the third time unit, when there are one or more CSI-RS resources on FR2, and one or more CSI-RS resources are all within the activation time, the channel state information of the second frequency domain resources included in the third channel state information report is: the channel state information obtained based on the most recent measurement of the second frequency domain resources from the third time unit.

[0149] It is understandable that in this embodiment, when the network device receives the CSI report reported by the terminal, it also needs to determine the CSI content contained in the CSI report, such as whether the CSI report only contains the channel state information of FR1, or includes the channel state information of FR1 and the channel state information of FR2. The network device can correctly parse the CSI report using the corresponding method only if it correctly determines the content contained in the CSI report. When the network device determines that CSI has never been received for FR2 in the current DRX cycle, the CSI report includes the channel state information of FR1 and FR2. If the network device determines that CSI has been received for FR2 in the current DRX cycle, the CSI report includes the channel state information of FR1 but does not include the channel state information of FR2.

[0150] Example 3:

[0151] See also Figure 13As shown, an embodiment of the present application provides another embodiment of a method for channel state measurement. In this embodiment, as long as the CSI-RS resource is within the activation time of any FR, the terminal will receive and measure the CSI-RS resource. For example, even if the CSI-RS resource of FR2 is outside the activation time of FR2, as long as it is within the activation time of FR1, the terminal will receive and measure the CSI-RS. For another example, even if the CSI-RS resource of FR1 is outside the activation time of FR1, as long as it is within the activation time of FR2, the terminal will receive and measure the CSI-RS.

[0152] Step 1301: The network device sends first configuration information to the terminal. Correspondingly, the terminal receives the first configuration information sent by the network device. The first configuration information is used to configure a first DRX parameter of a first frequency domain resource and a second DRX parameter of a second frequency domain resource.

[0153] This step refers to Figure 7 The description of step 701 in the corresponding embodiment is not repeated here.

[0154] Step 1302: The network device sends a CSI-RS of FR2. Accordingly, the terminal receives a reference signal (CSI-RS) in the second frequency domain resource, which is within the activation time of the first frequency domain resource and outside the activation time of the second frequency domain resource.

[0155] See also Figure 14A As shown, in an example, the activation time of FR1 is longer than the activation time of FR2. Before the fifth time unit, the terminal has reported a CSI report, and the CSI report already contains the channel state information obtained by measuring based on FR2CSI-RS1. The time domain position of FR2 CSI-RS2 is located after the time domain position of FR2 CSI-RS1. It is important to note that when FR2 CSI-RS2 is outside the activation time of FR2, but FR2 CSI-RS2 is within the activation time of FR1, the terminal will still receive and measure FR2 CSI-RS2 to obtain the channel state information of FR2. It should be noted that in Figure 14A In the example, the fifth time unit is described by taking the second reporting time as an example, however, the fifth time unit is not limited to the reporting time unit of the DRX cycle. For example, the fifth time unit may also be the first reporting time unit of the DRX cycle.

[0156] For example, see Figure 15A As shown, the step of the terminal determining whether to receive FR2 CSI-RS2 may include:

[0157] S31. Determine whether the FR2 reference signal (FR2 CSI-RS2) is within the FR2 activation time. If it is determined that the FR2 CSI-RS2 is outside the FR2 activation time, execute step S32. If the terminal determines that the FR2 CSI-RS2 is within the FR2 activation time, directly execute step S33.

[0158] S32, determining whether FR2 CSI-RS2 is within the activation time of FR1. If it is determined that FR2 CSI-RS2 is within the activation time of FR1, executing step S33; if it is determined that FR2 CSI-RS2 is outside the activation time of FR1, executing step S34;

[0159] S33: Receive and measure FR2 CSI-RS2 to obtain channel state information based on FR2 CSI-RS2.

[0160] S34. Execute other steps.

[0161] See also Figure 14B As shown in another example, the activation time of FR2 is longer than the activation time of FR1. When FR1 CSI-RS2 is outside the activation time of FR1 but within the activation time of FR2, the terminal will still receive and measure FR1 CSI-RS2 to obtain the channel state information of FR1. The terminal can report the channel state information of FR1 and FR2 in the next DRX cycle.

[0162] For example, see Figure 15B As shown, the step of the terminal determining whether to receive FR1 CSI-RS2 may include:

[0163] S41. Determine whether the reference signal of FR1 (FR1 CSI-RS2) is within the activation time of FR1. If it is determined that FR1 CSI-RS2 is outside the activation time of FR1, execute step S32. If the terminal determines that FR1 CSI-RS2 is within the activation time of FR1, directly execute step S43.

[0164] S42, determining whether FR1 CSI-RS2 is within the activation time of FR2. If it is determined that FR1 CSI-RS2 is within the activation time of FR2, executing step S43; if it is determined that FR1 CSI-RS2 is outside the activation time of FR2, executing step S44;

[0165] S43: Receive and measure FR1 CSI-RS2 to obtain channel state information based on FR1 CSI-RS2.

[0166] S44. Execute other steps.

[0167] It should be noted that the above Figure 15A and Figure 15B The corresponding examples are merely illustrative for ease of understanding and do not limit the present application. Figure 15A In the corresponding example, S31 and S32 can also be performed in one step. Figure 15B In the corresponding example, S41 and S42 may also be performed in one step, but the specific steps are not limited thereto.

[0168] Step 1303: The terminal sends a fifth channel state information report through a fifth uplink transmission resource (such as PUCCH5) in a fifth time unit. Correspondingly, the network device receives the fifth channel state information report in the fifth time unit.

[0169] The fifth channel state information report includes channel state information of the second frequency domain resource obtained according to a reference signal (such as FR2 CSI-RS2), where the reference signal is a reference signal before the fifth time unit and closest to the fifth time unit.

[0170] It will be understood that in this embodiment, the "union" of the activation time of FR1 and the activation time of FR2 is used as the activation time of FR2. As long as FR2 CSI-RS 2 is within the "union", the terminal will receive and measure FR2 CSI-RS 2 to obtain FR2 channel measurement information. That is, although FR2 CSI-RS 2 is not within the activation time of FR2, it is still within the activation time of FR1, and the terminal will still receive and measure FR2 CSI-RS 2. At the same time, the fifth channel state information report (CSI report) reported in the fifth time unit includes the channel state information of FR1 and FR2.

[0171] In this embodiment, the terminal can report the latest channel state information, which enhances the real-time performance of the network device in acquiring the channel state information and facilitates the network device in performing scheduling and / or beam management.

[0172] Optionally, the channel state information measurement items in the CSI report in this embodiment may include at least one of the following: CQI, PMI, LI, RI, CRI, SSBRI, L1-RSRP, and L1-SINR. The method of this embodiment can be used for all measurement items or only for certain measurement items. The terminal reports CSI to the network device, and the network device performs scheduling adjustments and / or beam management-related tasks based on the reported content.

[0173] It is understandable that in this embodiment, when the network device receives the CSI report reported by the terminal, it also needs to determine the CSI content contained in the CSI report, such as whether the CSI report only contains the channel state information of FR1, or includes the channel state information of FR1 and the channel state information of FR2. The network device can correctly parse the CSI report using the corresponding method only if it correctly determines the content contained in the CSI report. When the network device determines that the FR2 CSI-RS2 is outside the activation time of FR2, it determines whether the FR2 CSI-RS2 is within the activation time of FR1. When the FR2 CSI-RS2 is within the activation time of FR1, the network device determines that the CSI report received in the fifth time unit contains the channel state information of FR1 and FR2.

[0174] Example 4:

[0175] See also Figure 16 As shown, another embodiment of a channel state measurement method is provided in the embodiment of the present application. In this embodiment, the CSI content included in the CSI report is indicated by configuration information, that is, whether the CSI report includes FR2 channel state information is indicated by configuration information.

[0176] Step 1601: A terminal receives first configuration information and second configuration information sent by a network device. Correspondingly, the network device sends the first configuration information and the second configuration information.

[0177] The first configuration information is used to configure a first DRX parameter for the first frequency domain resource and to configure a second DRX parameter for the second frequency domain resource.

[0178] The terminal may determine the activation time of FR2 according to the second DRX parameter.

[0179] For the description of the first configuration information, please refer to Figure 7 The description of step 701 in the corresponding embodiment.

[0180] The second configuration information is used to indicate whether the sixth channel state information report includes the channel state information of the second frequency domain resource. The second configuration information can be configured through RRC parameters or MAC CE.

[0181] The second configuration information includes first information or second information, wherein the first information is used to indicate that the CSI report reported by the terminal needs to carry the channel state information of FR2, and the second information is used to indicate that the CSI report reported by the terminal does not need to carry the channel state information of FR2.

[0182] Step 1602: The terminal sends a sixth channel state information report using a sixth uplink transmission resource in a sixth time unit. Correspondingly, the network device receives the sixth channel state information report in the sixth time unit.

[0183] The sixth time unit is outside the activation time of the second frequency domain resource. Whether the sixth channel state information report includes the channel state information of the second frequency domain resource is indicated based on the second configuration information. For example, when the second configuration information includes the first information, the sixth channel state information report includes the channel state information of FR1 and the channel state information of FR2. When the second configuration information includes the second information, the sixth channel state information report includes the channel state information of FR1 but does not include the channel state information of FR2.

[0184] In this embodiment, the terminal first determines whether the sixth time unit is within the activation time of FR2. When the terminal determines that the sixth time unit is outside the activation time of FR2, the terminal determines the CSI content in the sixth channel state information report based on the second configuration information. In this embodiment, the network device has greater flexibility. The network device can determine the reporting behavior of the terminal through the second configuration information, thereby reducing the judgment steps of the terminal.

[0185] Optionally, the channel state information measurement items in the CSI report in this embodiment may include at least one of the following: CQI, PMI, LI, RI, CRI, SSBRI, L1-RSRP, and L1-SINR. The method of this embodiment can be used for all measurement items or only for certain measurement items. The terminal reports CSI to the network device, and the network device performs scheduling adjustments and / or beam management-related tasks based on the reported content.

[0186] Optionally, when there are one or more CSI-RS resources on FR2, and the one or more CSI-RS resources are within the activation time of FR2, the terminal receives and measures one or more CSI-RS resources, and the terminal determines to use the channel state information obtained by measuring the second frequency domain resource most recently from the sixth time unit as the reported channel state information of FR2, that is, the channel state information of the second frequency domain resource included in the sixth channel state information report is: the channel state information obtained by measuring the second frequency domain resource most recently from the sixth time unit.

[0187] In the embodiments of the present application, the methods in the above different embodiments can be used for different measurement items. For example, for channel state information used to assist base station scheduling, such as PMI, RI, CQI and other measurement items, the method in embodiment 1 can be used for measurement and reporting. For channel state information for beam management, such as CRI, SSBRI, L1-RSRP, L1-SINR and other measurement items, the method in embodiment 3 can be used for measurement and reporting. The methods in different embodiments can be applied for different scenarios, which can ensure the performance of different measurement items and have flexibility.
