FIG. 2 is a schematic flowchart of a window configuration method for tracking reference signals provided by an embodiment of the present disclosure. It should be noted that the method in the embodiment of the present disclosure is executed by a network device.

As shown in Figure 2, the window configuration method for tracking the reference signal includes the following steps:

Step 201, sending window configuration information to a terminal device in an unconnected state, where the window configuration information is used to indicate that the tracking reference signal TRS of the terminal device in the window corresponding to the window configuration information is not valid.

Wherein, the unconnected state includes an idle state (IDLE) and an inactive state (INACTIVE). In related technologies, in order to save power consumption, the terminal device in the non-connected state will periodically enter the sleep state, and then wake up at a designated PO position to receive paging. A terminal device in a non-connected state can wake up when needed, and perform time-frequency synchronization according to the received TRS. For example, a terminal device wakes up before the PO position to receive a TRS for time-frequency synchronization.

It should be noted that the network device can flexibly configure the TRS, such as time domain resources, frequency domain resources, periods, windows, etc. of the TRS, or use a fixed pattern to indicate the above information of the TRS.

In addition, it should be noted that the window configuration information is the information of the window where the network device configures the TRS.

Wherein, the windows may be fixedly configured, or flexibly configured as required. For example, the length and position of the configuration window may be fixed, or the length and position of the window may be configured as required. The periodic window can also flexibly configure the period according to the needs. The above information can be configured or indicated in the window configuration information, or the network device can notify the terminal device before sending the window configuration information, or there can be a pre-set agreement between the network device and the terminal device.

In some embodiments, the foregoing network device may choose to send the TRS within the window, and correspondingly not send the TRS outside the window. In some other embodiments, the foregoing network device may choose not to send the TRS within the window, and correspondingly send the TRS outside the window.

In some embodiments, the network device may also indicate the validity of the TRS through signaling, that is, the network device may indicate through signaling whether the TRS received by the terminal device is valid. Wherein, the foregoing signaling may be physical layer signaling, and may also be high layer signaling.

In the embodiments of the present disclosure, the window configuration information is used to indicate that the TRS of the terminal device in the window corresponding to the window configuration information is not valid, which means that the terminal device is in the window corresponding to the window configuration information The received TRS is invalid, that is, the terminal device does not use the TRS received within the window to perform time-frequency synchronization.

It can be understood that, in the window, the terminal device may or may not receive the TRS. That is to say, in the window, the network device can choose whether to share the TRS with the terminal device.

To sum up, the window configuration information is sent to the terminal device in the non-connected state through the network device, and the window configuration information is used to indicate that the tracking reference signal TRS of the terminal device in the window corresponding to the window configuration information does not take effect, so that the network device can It is selected whether to send TRS in the window without causing abnormal behavior of the terminal device, thereby saving power consumption of the terminal, reducing energy consumption of the network device, saving power, and saving resources.

Based on the above-mentioned embodiments, in some embodiments, the above-mentioned window configuration information includes first window length indication information, and the first window length indication information is used to indicate to select the selected window length from at least one window length configuration value. The window length configuration value of the window, each of the at least one window length configuration value is determined according to the period of the TRS and is smaller than the period of the TRS.

Among them, the window length can have multiple configurations, including a configuration with a window length of 0, and generally no more than four length configuration values. The window length configuration information is used to configure the at least one window length configuration value.

Optionally, the window length configuration information further configures the correspondence between the first window length indication information and the at least one window length configuration value, that is, according to the first window length indication information, the at least one window length configuration value Select the corresponding configuration value as the window length.

Further, the window length configuration value is determined according to the period of the TRS. For example, if the TRS period is T, then the window length configuration information configuration: 00 indicates the window length is T/2, 01 indicates the window length is T/4, 10 indicates the window length is T/8, and 11 indicates the window length is 0.

It can be understood that the network device needs to send the flexibly configured window length to the terminal device, so that the terminal device can find the corresponding window according to the indication of the window configuration information, and determine that the TRS received in the corresponding window is not valid.

In some other embodiments, the above window length configuration information may be sent to the terminal device together with the window configuration information. In some other embodiments, the above window length configuration information may be specified by a preset protocol between the network device and the terminal device.

In some other embodiments, the above window configuration information includes second window length indication information, and the second window length indication information is used to indicate the association relationship between the window length configuration value of the window and the period of the TRS.

For example, 2 bits are still used to represent the four window length configuration values, assuming that the second window length indication information is 00, 00 is used to indicate the relationship between the window length configuration value of the window and the TRS cycle, further, 00 can indicate the length of the window It is 1/2 of the TRS period.

The embodiment of the present disclosure provides another window configuration method for tracking reference signals. FIG. 3 is a schematic flowchart of another window configuration method for tracking reference signals provided by the embodiment of the present disclosure. The window configuration method for tracking reference signals can be configured by the network device, the window configuration method for tracking reference signals can be executed alone, or in combination with any embodiment in the present disclosure or a possible implementation in the embodiment, or in combination with any of the related technologies The technical solutions are implemented together.

As shown in Figure 3, the window configuration method for tracking the reference signal may include the following steps:

Step 301, sending window length configuration information to a terminal device, where the window length configuration information is used to configure at least one window length configuration value.

Optionally, the window length configuration information also configures the correspondence between the first and/or second window length indication information and the at least one window length configuration value, for example, using 2-bit indication information to indicate four kinds of window lengths, Configure the corresponding relationship between the indication information "00 01 10 11" and the four window lengths in the window length configuration information, for example, 00 indicates the first window length, 01 indicates the second window length, and 10 indicates the third window length. 11 indicates a fourth window length.

In some embodiments, the network device may send the window length configuration information through the first high layer signaling. Wherein, the above-mentioned first high-layer signaling may include radio resource control (Radio Resource Control, RRC) signaling and/or medium access control (Medium Access Control, MAC) control element (Control Element, CE) MAC-CE signaling.

In some other embodiments, the network device may send the window length configuration information through the first physical information.

Step 302, sending window configuration information to a terminal device in an unconnected state, where the window configuration information is used to indicate that the tracking reference signal TRS of the terminal device in the window corresponding to the window configuration information is not valid.

Optionally, the window configuration information includes first window length indication information, and the first window length indication information is used to indicate to select a window length configuration value of the window from at least one window length configuration value, and the at least one Each of the window length configuration values is determined according to the period of the TRS and is smaller than the period of the TRS.

As described in step 301, the window length can have multiple configurations, and the first window length indication information is used to select the configuration value of the window from at least one configured window length, for example, 2 bits are used to represent 4 window length configurations Assuming that the first window length indication information is 01, 01 is used to indicate that the length of the window is the corresponding window length configuration value, that is, select the length of the window from the 4 window length configuration values.

Further, each window length configuration is determined according to the period of the TRS and is smaller than the period of the TRS. For example, if the TRS period is T, then the window length configuration value may be T/2, T/4, and so on.

As mentioned above, the window length configuration value is determined according to the period of the TRS. Still use 2bit to represent four kinds of window length configuration values, assuming that the second window length indication information is 00, 00 is used to indicate the relationship between the window length configuration value of the window and the TRS cycle, further, 00 can indicate that the window length is TRS 1/2 of the cycle.

In an embodiment, the network device sends the window configuration information through the second physical layer signaling or the second high layer signaling indicating that the TRS takes effect.

Wherein, the second high-level signaling may be RRC (Radio Resource Control, radio resource control) signaling, that is, the network device may send window configuration information through the RRC signaling.

Further, the indication information is sent to the terminal device through third high layer signaling, where the indication information is used to indicate whether the second physical layer signaling takes effect. That is to say, the network device can also indicate whether the second physical layer signaling takes effect through the third high-level signaling, and whether the second physical layer signaling takes effect depends on the high-level configuration.

It should be noted that if the third high-level signaling indicates that the second physical layer signaling takes effect, the window configuration information included in the second physical layer signaling takes effect, that is, according to the foregoing method, the window configuration information indicates that the The TRS within the window does not take effect, and the length of the window is selected from at least one length configuration value by the first or second window length indication information. If the third high-level signaling indicates that the second physical layer signaling does not take effect, the window configuration information included in the second physical layer signaling does not take effect, that is, the corresponding window is not configured, or the length of the window is set to 0, that is, the terminal TRS information can be tracked throughout the TRS cycle.

In addition, it should be noted that the window length configuration information in step 301 and the window configuration information in step 302 may be sent in the same signaling, or may be sent in different signalings. That is to say, the window length configuration information and the window configuration information may be sent through the same high-layer signaling or physical layer signaling, or the window length configuration information and the window configuration information may be sent through different signaling . The signaling carrying the window length configuration information and the window configuration information may be high-layer signaling or physical layer signaling.

Step 401, receiving window configuration information.

In related technologies, in order to save power consumption, the terminal device in the non-connected state will periodically enter the sleep state, and then wake up at a designated PO position to receive paging. A terminal device in a non-connected state can wake up when needed and perform time-frequency synchronization according to the received TRS. For example, a terminal device wakes up before the PO position to receive a TRS for time-frequency synchronization.

In addition, it should be noted that the window configuration information is the information of the window in which the network device configures the TRS, where the window may be fixedly configured or flexibly configured as required. For example, the length and position of the window can be configured fixedly, or the length and position of the window can be configured according to the needs, and the period of the periodic window can also be flexibly configured according to the needs. The above information can be configured or indicated in the window configuration information, or the network device can notify the terminal device before sending the window configuration information, or there can be a pre-set agreement between the network device and the terminal device.

It can be understood that the TRS received by the terminal device outside the window is valid, that is, the terminal device can use the TRS received outside the window to perform time-frequency synchronization according to its own needs.

It can also be understood that, in the window, the terminal device may or may not receive the TRS, that is to say, in the window, in some embodiments, the above-mentioned network device may choose to be in the window Send, corresponding to not send TRS outside the window. In some other embodiments, the foregoing network device may choose not to send the TRS within the window, and correspondingly send the TRS outside the window.
