[0093] The method for indicating validity of a reference signal and the apparatus thereof provided by the present application will be described in detail below with reference to the accompanying drawings.

[0094] Figure 2 A flowchart of a method for indicating validity of a reference signal is provided for the embodiments of the present disclosure. It should be noted that the method of the embodiments of the present disclosure is executed by a network device.

[0095] As shown in Figure 2 , the method for indicating validity of a reference signal comprises the following steps:

[0096] In step 201, validity indication information is sent to a terminal device in a non-connected state, and the validity indication information is used to indicate that the reference signal received by the terminal device in a validity time period corresponding to the validity indication information is valid.

[0097] The non-connected state includes an idle state (IDLE) and an inactive state (INACTIVE). In the related art, the terminal device in the non-connected state can wake up when needed and perform time-frequency synchronization according to the received reference signal for time-frequency tracking, for example, the terminal device wakes up to receive the reference signal for time-frequency synchronization before the PO (Paging Occasion, paging occasion) position. Optionally, the reference signal is a synchronization signal block SSB, a tracking reference signal TRS, or a channel state information reference signal CSI-RS.

[0098] It should be noted that the network device can flexibly configure the reference signal for time-frequency tracking, such as the time domain resource, the frequency domain resource, the period, the window, etc. of the reference signal, or use a fixed pattern to indicate the above information of the reference signal.

[0099] In addition, it should be noted that the validity indication information is information configured by the network device to indicate that the reference signal received by the terminal device is valid, that is, the validity indication information is used to indicate that the reference signal received by the terminal device in the validity time period corresponding to the validity indication information is valid.

[0100] The validity time period is a period of time, and the reference signal received by the terminal device in this period of time is valid. It can be understood that the terminal device can know the validity time period corresponding thereto from the received validity indication information.

[0101] In some embodiments, the validity indication information is used to indicate the validity time period configuration information selected from at least one validity time period configuration information.

[0102] The validity time period configuration information refers to information for configuring the validity time period, that is, information for configuring the length of time of the validity time period.

[0103] Optionally, the effective time period configuration information includes first effective time period configuration information and at least one second effective time period configuration information.

[0104] The first effective time period configuration information is used to indicate that all time periods after the receiving time point of the effective indication information are effective time periods, and the second effective time period configuration information includes a time length configuration value, which is used to indicate that a time period with the time length configuration value after the receiving time point of the effective indication information is an effective time period.

[0105] In the embodiments of the present disclosure, the network device can flexibly configure the effective indication information and the corresponding effective time period according to different terminal devices and network deployments, and can flexibly configure and select the effective time period configuration information.

[0106] In some embodiments, the effective indication information sent by the network device is used to indicate that the first effective time period configuration information is selected, that is, the effective indication information sent by the network device is used to indicate that all time periods after the receiving time point of the effective indication information are effective time periods. In this case, in some embodiments, the network device can also send invalidation indication information to the terminal device, and the invalidation indication information is used to indicate that the reference signal in all time periods after the receiving time point of the invalidation indication information is invalid. That is, the reference signal received by the terminal device in all time periods after the receiving of the invalidation indication information is invalid.

[0107] Optionally, the effective indication information and / or the at least one effective time period configuration information is carried in the reference signal configuration information and sent to the terminal device.

[0108] As a first possible implementation, the network device sends the reference signal configuration information carrying the effective indication information to the terminal device.

[0109] As a second possible implementation, the network device sends the reference signal configuration information carrying the at least one effective time period configuration information to the terminal device.

[0110] As a third possible implementation, the network device sends the reference signal configuration information carrying the effective indication information and the at least one effective time period configuration information to the terminal device.

[0111] In some embodiments, the network device is configured with physical layer indication information, the physical layer indication information carries the effective indication information, and the network device sends the effective indication information by sending the physical layer indication information to the terminal device, wherein the physical layer indication information is configured by a higher layer.

[0112] In some embodiments, the network device is not configured with the physical layer indication information, and the network device sends the effective indication information to the terminal device by sending high layer indication information carrying the effective indication information.

[0113] In some embodiments, the network device can also send window configuration information to the terminal device, the window configuration information being used to indicate that the network device stops sending reference signals in a window corresponding to the window configuration information, wherein the window is located in the effective time period.

[0114] In summary, by sending the effective indication information to the terminal device in the non-connected state by the network device, the effective indication information is used to indicate that the reference signals received by the terminal device in the effective time period corresponding to the effective indication information are effective, so that the terminal device can receive the reference signals in the effective time period according to the configuration information, save the power, save the resources, and the network device can also flexibly configure the effective time period to reduce the system overhead.

[0115] The embodiment of the present disclosure provides another effective indication method of reference signals, Figure 3 The flowchart of another effective indication method of reference signals provided by the embodiment of the present disclosure, the effective indication method of reference signals can be executed by the network device, the effective indication method of reference signals can be executed alone, can be executed in combination with any embodiment or possible implementation manner in the present disclosure, and can be executed in combination with any technical solution in the related art.

[0116] As Figure 3 shown, the effective indication method of reference signals can include the following steps:

[0117] Step 301, sending at least one effective time period configuration information to the terminal device.

[0118] Optionally, the at least one effective time period configuration information includes first effective time period configuration information and at least one second effective time period configuration information.

[0119] The first effective time period configuration information is used to indicate that all time periods after the receiving time point of the effective indication information are effective time periods, and the second effective time period configuration information includes a time length configuration value, which is used to indicate that the time period with the time length configuration value after the receiving time point of the effective indication information is the effective time period.

[0120] In some embodiments, the at least one second validity time period configuration information comprises at least one time length configuration value, and the time length configuration value is related to a discontinuous reception (DRX) cycle of the terminal device. Optionally, the at least one time length configuration value is {2n, 4n, 8n, 16n}, where n is the DRX cycle of the terminal device.

[0121] It can be understood that the DRX cycle described above can also be flexibly configured as needed.

[0122] It should be noted that in the embodiments of the present disclosure, the network device can flexibly configure the validity indication information and the corresponding validity time period according to different terminal devices and network deployments, and can flexibly configure and select the validity time period configuration information.

[0123] In step 302, the validity indication information is sent to the terminal device in the non-connected state, and the validity indication information is used to indicate the validity time period configuration information selected from the at least one validity time period configuration information.

[0124] The reference signal is a synchronization signal block (SSB), a tracking reference signal (TRS), or a channel state information reference signal (CSI-RS).

[0125] In some embodiments, the validity indication information sent by the network device is used to indicate the selection of the first validity time period configuration information, that is, the validity indication information sent by the network device is used to indicate that all time periods after the reception time point of the validity indication information are validity time periods. In this case, in some embodiments, the network device sends invalidation indication information to the terminal device, and the invalidation indication information is used to indicate that the reference signal in all time periods after the reception time point of the invalidation indication information is invalid. That is, the reference signal received by the terminal device in all time periods after the reception of the invalidation indication information is invalid.

[0126] In some embodiments, the validity indication information sent by the network device is used to indicate the selection of one of the at least one second validity time period configuration information, that is, the validity indication information sent by the network device is used to indicate that the time period with the corresponding time length configuration value after the reception time point of the validity indication information is the validity time period. For example, the validity indication information is used to indicate that one of the at least one second validity time period configuration information {2n, 4n, 8n, 16n} is selected, and the time length configuration value included in the second validity time period configuration information 2n is 2n. Then, the validity indication information is used to indicate that the time period of 2n after the reception time point of the validity indication information is the validity time period, where n is the DRX cycle of the terminal device.

[0127] In addition, it should be noted that the effective time period configuration information in step 301 and the effective indication information in step 302 can be sent at the same time in the reference signal configuration information, or can be sent at different times. The signaling carrying the effective indication information can be high-layer indication information or physical-layer indication information.

[0128] In some embodiments, the network device can also send window configuration information to the terminal device, the window configuration information being used to indicate that the network device stops sending reference signals in a window corresponding to the window configuration information, wherein the window is located in the effective time period. By configuring the window, the network device stops sending reference signals in the window, thereby reducing the power consumption of the network device.

[0129] In summary, by sending at least one effective time period configuration information to the terminal device in the non-connected state, sending the effective indication information to the terminal device in the non-connected state, the effective indication information being used to indicate the effective time period configuration information selected from the at least one effective time period configuration information, and indicating the terminal device to activate the reference signal received in the effective time period, the terminal device can receive the reference signal in the effective time period according to the configuration information, thereby saving power, reducing power consumption, saving resources, and the network device can also flexibly configure the effective time period, thereby reducing system overhead.

[0131] As shown in the method for indicating the effectiveness of a reference signal, the method can include the following steps. Figure 4
