technical field

The present disclosure relates to but not limited to the technical field of communication, and in particular, relates to a reference signal processing method, device, communication device, and storage medium.

Background technique

At present, it is proposed to use an additional tracking reference signal (Tracking Refernece Signal, TRS) or channel state information reference signal (Channel State Information-Reference Signal, CSI-RS) in the idle state to assist the user in acquiring and synchronizing the time-frequency domain of the network. Compared with the original synchronization signal block (Synchronization Signal Block, SSB) synchronization, using TRS and/or CSI-RS for synchronization can make the UE wake up later, so it can save more power.

At present, TRS and/or CSI-RS are mainly used for connected state user equipment (User Equipment, UE), and non-connected state UE can also use the TRS and/or CSI-RS when it needs to perform connection and other processing. However, when the UE in the connected state withdraws, the base station usually turns off the transmission of TRS and/or CSI-RS, so that the UE in the non-connected state cannot receive reference signals such as TRS and/or CSI-RS to process related services.

In order to better understand the technical solution described in any embodiment of the present disclosure, first, a partial explanation is given for the synchronization of the TRS and/or CSI-RS between the base station and the UE:

As shown in FIG. 2 , in one embodiment, the availability indication of TRS and/or CSI-RS configurations indicates that the update period is multiplexed with the system information update period; for example, T2 is an update time of a system information update period. If at T1 time before the update time (T2) of the system message, the connected UE withdraws; for example, UE1, UE2, and UE3 all withdraw; then the base station will not send TRS and/or CSI-RS from T1, that is, from T1 There are no TRS and/or CSI-RS resources at the beginning of time. If the availability indication of the TRS and/or CSI-RS configuration configured by UE1, UE2 and UE3 needs to be updated at T2, the UE in the unconnected state will also use the original TRS and/or CSI-RS configuration to obtain paging synchronously DCI; then the unconnected UE will still use the TRS and/or CSI-RS configuration before updating to synchronize, but at this time the unconnected UE has not been able to listen to the TRS and/or CSI-RS after T1. That is to say, the UE in the non-connected state will use wrong TRS and/or CSI-RS configurations for synchronization between time T1 and time T2, thereby reducing the accuracy of synchronization between the UE and the base station.

In this embodiment, when TRS and/or CSI-RS are changed from sending (on) to not sending (off) at time T1, the configuration of wrong TRS and/or CSI-RS for UE in non-connected state will occur. In the case of synchronization; when the TRS and/or CSI-RS are changed from not sending (off) to sending (off) at T1, there will be no wrong TRS and/or CSI-RS configuration for the UE in the non-connected state The case where the synchronization takes place.

As shown in FIG. 3, an embodiment of the present disclosure provides a reference signal processing method, which is executed by a base station, including:

Step S31: In response to the connected state UE evacuating at the first moment, continue to send the reference signal according to the configuration of the reference signal of the connected state UE between the first moment and the second moment; the second moment is later than the first moment.

In an embodiment, the base station may be an interface device for the UE to access the Internet. The base station may be various types of base stations; for example, 3G base stations, 4G base stations, 5G base stations or other evolved base stations.

In one embodiment, the UE may be various mobile terminals or fixed terminals. For example, the UE may be, but not limited to, a mobile phone, a computer, a server, a wearable device, a game control platform, or a multimedia device.

In one embodiment, the UE includes a UE in a connected state and a UE in a non-connected state; wherein, the UE in a non-connected state includes: a radio resource control (Radio Resource Control, RRC) idle state UE and/or an RRC inactive state UE. When events such as the UE handover target cell connection and/or radio link disconnection occur, the UE in the connected state may evacuate; of course, in other embodiments, the UE in the connected state may also evacuate caused by other triggering events.

In one embodiment, the reference signal includes: TRS and/or CSI-RS.

In an embodiment, the second moment may include an effective time agreed in advance by the base station and the terminal.

As an embodiment, the second time is the time when the system message is updated or the time when the system message is received. In this way, in the embodiment of the present disclosure, the base station can continue to send TRS and/or CSI-RS according to the UE in the connected state between the time when the UE in the connected state withdraws and the time when the system information is updated, so that the UE in the unconnected state can still Receive the reference signal at the position of the reference signal of the original connected UE before the system message update time; this can greatly reduce the situation that the non-connected UE cannot receive TRS and/or CSI-RS due to the evacuation of the connected UE ; In turn, the accuracy of reference signal synchronization between the base station and the UE can be improved.

In an embodiment, the update period of the availability indication of the reference signal is multiplexed with the update period of the system message, that is, the update period of the availability indication of the reference signal is the same as the update period of the system message; wherein the reference signal includes TRS and/or CSI -RS. In this way, when the system information is updated, the availability indication will also be updated; and if the system information carries the availability indication of TRS and/or CSI-RS, the system information and the availability indication of TRS and/or CSI-RS can be updated synchronously .

In one embodiment, the availability indication of the reference signal is at least used for determining the availability status of the configuration of the reference signal.

In one embodiment, the availability indication includes one of the following:

Status indication, indicating the availability status of the configuration of the reference signal; wherein, the availability status includes: available status and/or unavailable status;

The state change indication indicates the change of the availability state of the configuration of the reference signal; wherein, the state change indication includes: the configuration of the reference signal changes from an available state to an unavailable state; or, the configuration of the reference signal changes from an unavailable state to available status.

In an embodiment, the availability indication may also be: a change in the configuration of the reference signal results in a change in the available state. For example, the deletion of the configuration of the reference signal causes the availability state of the reference signal to change from the available state to the unavailable state.

In one embodiment, if the UE successfully receives the configuration of the reference signal assigned by the base station for the UE, the configuration of the reference signal is available; if the UE fails to receive the configuration of the reference signal assigned by the base station for the UE, the configuration of the reference signal is unavailable state. Here, the UE successfully receives the configuration of the reference signal allocated by the base station to the UE, which may refer to: the base station allocates the configuration of the reference signal to the UE, and the UE successfully receives the configuration of the reference signal allocated by the UE. Here, the UE fails to receive the configuration of the reference signal assigned by the base station to the UE, which may refer to: the configuration of the reference signal assigned by the base station to the UE, but the UE fails to receive the configuration of the reference signal assigned by the UE; or it may refer to : The base station does not allocate the configuration of the reference signal to the UE.

In the embodiment of the present disclosure, if the update cycle of the availability indication of the reference signal is multiplexed with the update cycle of the system message; then it is possible to ensure that the transmission of the reference signal between the UE and the base station is synchronized before the update time of the system message; and when the system message is updated The availability indication of the reference signal is updated synchronously from time to time, so that the UE knows the configuration availability status of the reference signal in time, and further improves the synchronization accuracy of the reference signal transmission between the UE and the base station.

Of course, in other embodiments, if the update period of the availability indication of the reference signal does not reuse the update period of the system message, for example, the update period of the availability indication is greater than the update period of the system message, or the update period of the availability indication is the system message Integer multiples of the update period. In this way, it is also possible to ensure that the reference signal transmission between the UE and the base station is synchronized before the system message is updated; and it is also convenient for the base station to send an availability indication by means of the system message, so that the UE can know the availability status of the reference signal configuration after the system message update time Whether to update, to save resources of the base station and UE, etc.

In an embodiment, the second moment is: the update moment of the availability indication of the reference signal. In this way, in the embodiments of the present disclosure, the base station can be made to send the TRS and/or CSI-RS before the update of the availability indication of the reference signal, so as to ensure that the UE and Synchronization of TRS and/or CSI-RS transmission between base stations; thereby greatly reducing the possibility that the UE in the non-connected state cannot receive the reference signal before the availability state of the TRS and/or CSI-RS configuration is updated due to the evacuation of the UE in the connected state The situation arises. Moreover, the embodiments of the present disclosure can also improve the synchronization accuracy of the reference signal transmitted between the base station and the UE.

In one embodiment, the update time of the system message is: the boundary time of the update period of the system message; the update time of the availability indication is: the boundary time of the update period of the availability. For example, as shown in FIG. 2 , in an embodiment, both the system message update time and the availability update time are T2.

Certainly, in other embodiments, the second moment may also be other specific moments later than the first moment. For example, the system information update time is later than the first time; if the UE in the unconnected state has a paging opportunity at the third time between the first time and the system information update time, the second time may also be any time after the third time . In this way, in the embodiment of the present disclosure, the second time may also be other time, for example, it may be any time after T1 and after the paging occasion of the UE.

Certainly, in other embodiments, the second moment may also be any other moment later than the first moment. In this way, the base station will send the TRS and/or CSI-RS at least between the first moment and the second moment, so that the UE in the unconnected state can receive the TRS and/or CSI-RS.

In an embodiment, the configuration of the reference signal of the UE in the connected state includes: configuration of time-frequency domain resources of the reference signal of the UE in the connected state. For example, as shown in UE1 in Figure 2, if UE1 does not evacuate at the first moment, UE1 will receive the reference signal at the third moment (T3); when UE1 evacuates at the first moment, the base station will send the reference signal at T3.

In the embodiment of the present disclosure, the base station responds to the evacuation of the UE in the connected state at the first moment, and continues to send the reference signal according to the configuration of the reference signal of the UE in the connected state between the first moment and the second moment; wherein, the second moment is later than the second moment moment. In this way, the base station can continue to send the reference signal according to the UE in the connected state between the moment when the UE in the connected state withdraws and the second moment, so that the UE in the unconnected state can still receive the reference signal before the second moment; The unconnected UE fails to receive the reference signal due to the evacuation of the UE in the connected state. Moreover, the embodiment of the present disclosure can enable the UE in the non-connected state to receive the reference signal between the first moment and the second moment, thereby also improving the synchronization accuracy between the UE and the base station and facilitating the radio resource management (RRM) of the UE. ) measurement, etc.

If the UE in the connected state withdraws and becomes a UE in the unconnected state, the UE in the unconnected state may also receive the reference signal during the second time.

In some embodiments of the present disclosure, the second moment may be the second moment in step S21; the reference signal is the reference signal in step S21; and the availability indication is the availability indication in step S21.

Here, sending the availability indication of the reference signal at the second moment or at any time after the second moment may be considered as: determining that the availability indication of the reference signal takes effect at the second moment or at any time after the second moment.

In the embodiment of the present disclosure, the base station may send the availability indication of the reference signal at a specific time, that is, the second time or any time after the second time, so that the UE can know the TRS and/or CSI-RS at the specific time. The availability status of the configuration. In this way, the unconnected UE can know the availability status of the accurate TRS and/or CSI-RS configuration at or after the second moment, so that the unconnected UE will not use the wrong TRS and/or CSI - The configuration of the RS is synchronized, thereby improving the synchronization accuracy of the reference signal transmitted between the UE and the base station.

If the base station continues to send the reference signal between the first moment and the second moment, it can enable the UE in the non-connected state to receive the reference signal before the second moment and know the exact configuration of the reference signal after the second moment Availability indication; thereby greatly improving the accuracy of the reference signal transmission between the base station and the UE.

In this way, in this embodiment of the disclosure, even if the UE releases the connection between the first moment and the second time; but since the base station may not release the connection between the first moment and the second time, the base station may The delivery of the reference signal is ensured between the second moments, and the reference signal is not released until the base station notifies the UE of the availability indication of the reference signal. In this way, the synchronization of reference signal transmission between the base station and the UE can be realized.

A reference signal processing method provided by an embodiment of the present disclosure is executed by a base station, including: in response to receiving a reestablishment request message sent by a UE, performing a process of reestablishing a connection for the UE, and between the first moment and the second moment Continue to send the reference signal according to the configuration of the reference signal of the UE in the connected state.

Here, the base station does not release the connection in response to receiving the reestablishment request message sent by the UE. Here, the base station does not release the connection, which may mean that the base station does not release context information, for example, does not release TRS and/or CSI-RS.

In one embodiment, the process of reestablishing the connection of the UE is performed, including but not limited to one of the following:

Sending a connection re-establishment message to the UE; wherein, the connection re-establishment message instructs the UE to re-establish the connection;

Exemplarily, the base station receives the connection reestablishment request sent by the UE, and the base station does not release the connection of the base station; the base station still continues to send the reference signal according to the reference signal configuration of the UE in the connected state between the first moment and the second moment. In this embodiment, the base station does not release the connection and does not reestablish the connection. Although the UE has released the connection, the base station can still continue to send the reference signal at the time-frequency domain position where the UE originally sent the reference signal in the connected state, until the base station notifies the UE of the availability indication of the reference signal before releasing the connection and reestablishing the connection.

In this way, in the embodiment of the present disclosure, even if the base station performs connection re-establishment processing on the UE between the first moment and the second moment, the UE has released the connection; connection, the base station can also ensure the delivery of the production test signal, so as to realize the synchronization of reference signal transmission between the base station and the UE.

In response to receiving the connection release request message, perform the process of releasing the connection to the UE, and continue to send the reference signal according to the configuration of the reference signal of the UE in the connected state between the first moment and the second moment;

In response to triggering reconfiguration processing, perform UE reconfiguration processing, and continue to send reference signals before a predetermined time according to the configuration of the reference signal of the UE in the connected state between the first moment and the second moment;

In response to receiving the re-establishment request message sent by the UE, perform the process of re-establishing the connection of the UE, and continue to send the reference signal according to the configuration of the reference signal of the UE in the connected state between the first moment and the second moment.

In the embodiment of the present disclosure, when the base station receives the connection release request message sent by the base station of the core network or other cells, it may send a connection release message to the UE or delay sending the connection release message to the UE, so that the UE releases the connection. However, the base station may not release the connection between the first moment and the second moment, and the base station may continue to send the reference signal according to the reference signal configuration of the UE in the connected state between the first moment and the second moment. In this way, after the base station receives the connection release request message, it can still ensure the sending of the reference signal between the first moment and the second moment, so as to realize the synchronization of the reference signal between the base station and the UE. Moreover, if the base station delays sending the connection release message to the UE until after the base station sends the availability indication, it can further ensure the probability that the UE can receive the reference signal, thereby improving the synchronization accuracy between the base station and the UE.

Alternatively, when the base station triggers reconfiguration, it may also send a reconfiguration message to the UE, so that the UE performs reconfiguration processing; the second base station may not release the connection between the first moment and the second moment, and the base station may From the time to the second time, the reference signal is continued to be sent according to the configuration of the reference signal of the UE in the connected state. In this way, even when the UE performs reconfiguration processing or releases the connection, it can still receive the reference signal at the first moment and the second moment, so as to realize the synchronization of the reference signal between the base station and the UE.

Or, when the base station receives the reestablishment request message sent by the UE, it may send a reconnection message to the UE or delay sending the reconnection message to the UE, so that the UE can release the connection. However, the base station may not release or re-establish the connection between the first moment and the second moment; then the base station may continue to send reference signals according to the reference signal configuration of the UE in the connected state between the first moment and the second moment. In this way, after the base station receives the connection reestablishment message, it can still ensure the delivery of the reference signal between the first moment and the second moment, so as to realize the synchronization of the reference signal between the base station and the UE. Moreover, if the base station delays sending the connection reestablishment message to the UE until the base station sends the availability indication before sending the reconnection message, it can further ensure the probability that the UE can receive the reference signal, thereby improving the synchronization accuracy between the base station and the UE.
