[0002] Currently, it is proposed to use additional tracking reference signals (TRS) or channel state information-reference signals (CSI-RS) in the idle state to assist users in acquiring and network time-frequency domain synchronization.

[0036] Reference is made to Figure 1 which shows a structure diagram of a wireless communication system provided by the embodiments of the disclosure. As shown in Figure 1 , the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system can include a plurality of user equipment 110 and a plurality of base stations 120.

[0037] The user equipment 110 can be a device that provides voice and / or data connectivity to a user. The user equipment 110 can communicate with one or more core networks via a Radio Access Network (RAN), and the user equipment 110 can be an Internet of Things user equipment, such as a sensor device, a mobile phone (also known as a "cellular" phone), and a computer with an Internet of Things user equipment, for example, which can be fixed, portable, pocket, hand-held, computer-embedded, or vehicle-mounted. For example, a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment. Alternatively, the user equipment 110 can also be a device of an unmanned aerial vehicle. Alternatively, the user equipment 110 can also be a vehicle-mounted device, for example, it can be a vehicle-mounted computer with wireless communication function or a wireless user equipment externally connected to the vehicle-mounted computer. Alternatively, the user equipment 110 can also be a roadside device, for example, it can be a street lamp, a signal lamp, or other roadside devices with wireless communication function, etc.

[0038] The base station 120 can be a network-side device in a wireless communication system. The wireless communication system can be a 4th generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system, or the wireless communication system can also be a 5G system, also known as a New Radio system or a 5G NR system. Alternatively, the wireless communication system can also be a next generation of 5G system. In the 5G system, the access network can be referred to as a New Generation-Radio Access Network (NG-RAN).

[0039] The base station 120 can be an evolved NodeB (eNB) used in a 4G system. Alternatively, the base station 120 can also be a base station (gNB) using a centralized and distributed architecture in a 5G system. When the base station 120 uses a centralized and distributed architecture, it usually includes a central unit (CU) and at least two distributed units (DUs). The central unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer; and the distributed unit is provided with a protocol stack of a physical (PHY) layer. The specific implementation of the base station 120 is not limited in the embodiments of the present disclosure.

[0040] The base station 120 and the user equipment 110 can establish a wireless connection through a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on a fourth generation mobile communication network technology (4G) standard; or the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, such as a new radio (NR); or the wireless air interface can also be a wireless air interface based on a more next generation mobile communication network technology standard of 5G.

[0041] In some embodiments, the user equipment 110 can also establish an E2E (End to End) connection. For example, vehicle to vehicle (V2V) communication, vehicle to infrastructure (V2I) communication, and vehicle to pedestrian (V2P) communication in vehicle to everything (V2X) communication, and the like.

[0042] Here, the user equipment described above can be considered as a terminal device in the following embodiments.

[0043] In some embodiments, the wireless communication system can also include a network management device 130.

[0044] Several base stations 120 are connected to network management device 130. Network management device 130 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 130 is not limited in this embodiment.

[0045] To better understand the technical solutions described in any embodiment of this disclosure, the synchronization of TRS and / or CSI-RS between the base station and the UE will be partially explained first:

[0046] like Figure 2 As shown, in one embodiment, the availability indication update cycle of the TRS and / or CSI-RS configuration reuses the system message update cycle; for example, time T2 is the update time of a system message update cycle. If a connected UE user leaves at time T1 before the system message update time (T2); for example, UE1, UE2, and UE3 all leave; then the base station will not send TRS and / or CSI-RS from time T1, meaning there are no TRS and / or CSI-RS resources from time T1 onwards. If the availability indication of the TRS and / or CSI-RS configuration configured for UE1, UE2, and UE3 needs to be updated at time T2, then the disconnected UE will still use the original TRS and / or CSI-RS configuration for synchronization to obtain paging DCI; the disconnected UE will still use the TRS and / or CSI-RS configuration before the update for synchronization, but at this time the disconnected UE can no longer listen to TRS and / or CSI-RS after T1. In other words, the non-connected UE will use an incorrect TRS and / or CSI-RS configuration for synchronization between time T1 and time T2, thereby reducing the accuracy of synchronization between the UE and the base station.

[0047] In the embodiment, when the TRS and / or CSI-RS is turned from on to off at the T1 moment, the case that the non-connected state UE uses the wrong configuration of the TRS and / or CSI-RS to synchronize occurs; and when the TRS and / or CSI-RS is turned from off to on at the T1 moment, the case that the non-connected state UE uses the wrong configuration of the TRS and / or CSI-RS to synchronize does not occur.

[0048] As shown in Figure 3 The embodiment of the present disclosure provides a reference signal processing method, which is executed by a base station and includes the following steps:

[0049] Step S31: in response to the connected state UE leaving at the first moment, continuing 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.

[0050] In an embodiment, the base station can be an interface device for the UE to access the Internet. The base station can be various types of base stations; for example, a 3G base station, a 4G base station, a 5G base station, or other evolved base stations.

[0051] In an embodiment, the UE can be various mobile terminals or fixed terminals. For example, the UE can be, but is not limited to, a mobile phone, a computer, a server, a wearable device, a game control platform, a multimedia device, etc.

[0052] In an embodiment, the UE includes a connected state UE and a non-connected state UE; wherein the non-connected state UE includes a radio resource control (RRC) idle state UE and / or an RRC inactive state UE. When the connected state UE switches the target cell connection and / or the wireless link is disconnected, etc., it can cause the connected state UE to leave; of course, in other embodiments, the connected state UE leaving can also be caused by other trigger events.

[0053] In an embodiment, the reference signal includes a TRS and / or a CSI-RS.

[0054] In an embodiment, the second moment can include a valid time agreed by the base station and the terminal in advance.

[0055] As an embodiment, the second time is a system message update time or a receiving time of the system message. In this way, in the embodiments of the present disclosure, the base station can continue to send the TRS and / or the CSI-RS according to the connected state UE from the time when the connected state UE leaves to the system message update time, so that the non-connected state UE can still receive the reference signal at the original position of the reference signal of the connected state UE before the system message update time. In this way, the situation that the non-connected state UE cannot receive the TRS and / or the CSI-RS due to the leaving of the connected state UE can be greatly reduced, and the synchronization accuracy of the reference signal between the base station and the UE can be improved.

[0056] 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 the TRS and / or the CSI-RS. In this way, when the system message is updated, the availability indication is also updated; and if the availability indication of the TRS and / or the CSI-RS is carried in the system message, the system message and the availability indication of the TRS and / or the CSI-RS can be updated synchronously.

[0057] In an embodiment, the availability indication of the reference signal is at least used to determine the availability state of the configuration of the reference signal.

[0058] In an embodiment, the availability indication includes one of the following:

[0059] The state indication indicates the availability state of the configuration of the reference signal; wherein the availability state includes: an available state and / or an unavailable state;

[0060] 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 is changed from the available state to the unavailable state; or, the configuration of the reference signal is changed from the unavailable state to the available state.

[0061] In an embodiment, the availability indication can also be that the change of the configuration of the reference signal causes the change of the availability 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.

[0062] In one embodiment, if the UE successfully receives the configuration of the reference signal allocated by the base station for the UE, the configuration of the reference signal is in the available state; if the UE does not successfully receive the configuration of the reference signal allocated by the base station for the UE, the configuration of the reference signal is in the unavailable state. Here, the UE successfully receiving the configuration of the reference signal allocated by the base station for the UE can mean that the base station allocates the configuration of the reference signal for the UE, and the UE successfully receives the allocated configuration of the reference signal. Here, the UE not successfully receiving the configuration of the reference signal allocated by the base station for the UE can mean that the base station allocates the configuration of the reference signal for the UE, but the UE does not successfully receive the allocated configuration of the reference signal; or can also mean that the base station does not allocate the configuration of the reference signal for the UE.

[0063] In the embodiments of the present disclosure, if the update period of the availability indication of the reference signal multiplexes the update period of the system message, the transmission of the reference signal between the UE and the base station can be ensured to be synchronized before the update time of the system message; and the availability indication of the reference signal can be updated at the same time as the update of the system message, so that the UE can know the availability state of the configuration of the reference signal in time, and the synchronization accuracy of the transmission of the reference signal between the UE and the base station can be further improved.

[0064] Of course, in other embodiments, if the update period of the availability indication of the reference signal does not multiplex 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 an integer multiple of the update period of the system message. In this way, the transmission of the reference signal between the UE and the base station can also be ensured to be synchronized before the update of the system message; and the base station can also send the availability indication through the system message, so that the UE can know whether the availability state of the configuration of the reference signal is updated after the update time of the system message, and the resources of the base station and the UE are saved.

[0065] In one embodiment, the second time is the update time of the availability indication of the reference signal. In this way, in the embodiments of the present disclosure, the base station can send the TRS and / or the CSI-RS before the update of the availability indication of the reference signal, so that the transmission of the TRS and / or the CSI-RS between the UE and the base station can be ensured to be synchronized before the update of the availability state of the configuration of the TRS and / or the CSI-RS; and the situation that the non-connected state UE cannot receive the reference signal before the update of the availability state of the configuration of the TRS and / or the CSI-RS due to the disconnection of the connected state UE can be greatly reduced. The embodiments of the present disclosure can also improve the synchronization accuracy of the transmission of the reference signal between the base station and the UE.

[0066] In one embodiment, the update time of the system message is the boundary time of the update period of the system message; and 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, the update period of the system message is 160 ms, and the update period of the availability indication is 320 ms. The update time of the system message is the boundary time of the update period of the system message, and the update time of the availability indication is the boundary time of the update period of the availability.Figure 2 In one embodiment, the system message update time and the update time of availability are both T2.

[0067] Of course, in other embodiments, the second time can also be other specific times later than the first time. For example, the system message update time is later than the first time; the non-connected state UE has a paging occasion at a third time between the first time and the system message update time, then the second time can also be any time after the third time. Thus, in the embodiments of the present disclosure, the second time can also be other times, for example, can be any time after T1 and after the paging occasion of the UE.

[0068] Of course, in other embodiments, the second time can also be other arbitrary times later than the first time. Thus, at least between the first time and the second time, the base station will send TRS and / or CSI-RS, so that the non-connected state UE can receive the TRS and / or CSI-RS.

[0069] In one embodiment, the configuration of the reference signal of the connected state UE includes the configuration of the time-frequency domain resource of the reference signal of the connected state UE. For example, as Figure 2 In the UE1 in the embodiment of the present disclosure, if the UE1 does not leave at the first time, the UE1 will receive the reference signal at the third time (T3); when the UE1 leaves at the first time, the base station sends the reference signal at T3.

[0070] The embodiments of the present disclosure can make the base station continue to send the reference signal according to the configuration of the reference signal of the connected state UE between the first time and the second time in response to the connected state UE leaving at the first time; wherein the second time is later than the first time. Thus, the base station can continue to send the reference signal according to the connected state UE between the time when the connected state UE leaves and the second time, so that the non-connected state UE can still receive the reference signal before the second time; thus, the situation that the non-connected state UE cannot receive the reference signal due to the connected state UE leaving can be greatly reduced. Moreover, the embodiments of the present disclosure can make the non-connected state UE receive the reference signal between the first time and the second time, so as to also improve the accuracy of synchronization between the UE and the base station and be beneficial to the radio resource management (RRM) measurement of the UE, etc.

[0071] If the connected state UE leaves and becomes a non-connected state UE, the non-connected state UE can also receive the reference signal between the second time.

[0072] It should be noted that those skilled in the art can understand that the method provided by the embodiments of the present disclosure can be executed alone or together with some methods in some methods or related technologies in the embodiments of the present disclosure.

[0073] AsFigure 4 The embodiment of the present disclosure provides a processing method of a reference signal, executed by a base station, including:

[0074] Step S41: sending an availability indication of the reference signal at the second time or any time after the second time; wherein the availability indication is used for determining at least an availability state of a configuration of the reference signal.

[0075] In some embodiments of the present disclosure, the second time can be the second time in step S41; the reference signal can be the reference signal in step S41; and the availability indication can be the availability indication in step S41.

[0076] Here, the availability indication of the reference signal at the second time or any time after the second time can be considered as that the availability indication of the reference signal at the second time or any time after the second time is determined to take effect.

[0077] In the embodiment of the present disclosure, the availability indication of the reference signal can be sent by the base station at a specific time, i.e., the second time or any time after the second time, so that the UE can know the availability state of the configuration of the TRS and / or the CSI-RS at the specific time. In this way, the non-connected state UE can know the accurate availability state of the configuration of the TRS and / or the CSI-RS at the second time or after the second time, so that the non-connected state UE can not use the incorrect configuration of the TRS and / or the CSI-RS for synchronization, thereby improving the synchronization accuracy of the transmission of the reference signal between the UE and the base station.

[0078] If the base station continues to send the reference signal between the first time and the second time, the non-connected state UE can receive the reference signal before the second time and know the accurate availability indication of the configuration of the reference signal after the second time, thereby greatly improving the accuracy of the transmission of the reference signal between the base station and the UE.

[0079] The embodiment of the present disclosure provides a processing method of a reference signal, executed by a base station, including: in response to sending a paging message at the second time or any time after the second time, sending an availability indication of the reference signal at the second time or any time after the second time.

[0080] In one embodiment, the paging message includes but is not limited to a paging DCI, a PEI, and a short message.

[0081] In some embodiments, step S41 includes: in response to sending a paging message at the second time or any time after the second time, sending an availability indication of the reference signal at the second time or any time after the second time.

[0082] In the embodiments of the present disclosure, the base station sends the indication of availability of the reference signal at the second time or any time after the second time only when the base station estimates that the base station will send a paging message at the second time or any time after the second time. In this way, on the one hand, the UE can know the accurate availability state of the configuration of the TRS and / or the CSI-RS; on the other hand, since the base station sends the indication of availability of the reference signal only when the base station estimates that the base station will send a paging message later, the transmission resources, power consumption, and the like of the base station and the UE can be saved.

[0083] The embodiments of the present disclosure provide a method for processing a reference signal, performed by a base station, comprising: in response to the base station not sending a paging message at a second time or any time after the second time, the base station not sending an indication of availability of the reference signal at the second time or any time after the second time.

[0084] In the embodiments of the present disclosure, when the base station estimates that the base station will not send a paging message at the second time or any time after the second time, the base station will not send an indication of availability of the reference signal at the second time or any time after the second time; in this way, the availability state of the configuration of the reference signal can be timely notified to the UE without affecting the transmission resources, power consumption, and the like of the base station and the UE can be greatly saved.

[0085] In the embodiments of the present disclosure, the base station is recommended to send an indication of availability of the reference signal at the second time or any time after the second time, that is, the time point at which the base station sends the indication of availability of the reference signal is limited to a specific time point agreed by the base station and the terminal in advance.

[0086] In the embodiments of the present disclosure, the base station is recommended to send an indication of availability of the reference signal at the second time or any time after the second time, which is not a mandatory behavior of the base station.

[0087] It should be noted that those skilled in the art can understand that the method provided by the embodiments of the present disclosure can be executed alone or together with some methods in some methods or related technologies in the embodiments of the present disclosure.

[0088] As shown in FIG. 1, Figure 5 The embodiments of the present disclosure provide a method for processing a reference signal, performed by a base station, comprising:

[0089] Step S51: in response to receiving the connection release request message, performing the processing of releasing the connection of the UE, and continuing to send the reference signal according to the configuration of the reference signal of the connected state UE between the first time and the second time; or, in response to triggering the reconfiguration processing, performing the processing of reconfiguring the UE, and continuing to send the reference signal according to the configuration of the reference signal of the connected state UE before a predetermined time between the first time and the second time; or, in response to receiving the reestablishment request message sent by the UE, performing the processing of reestablishing the connection of the UE, and continuing to send the reference signal according to the configuration of the reference signal of the connected state UE between the first time and the second time.

[0090] The embodiment of the present disclosure provides a processing method of a reference signal, executed by a base station, comprising: in response to receiving a connection release request message, performing the processing of releasing the connection of the UE, and continuing to send the reference signal according to the configuration of the reference signal of the connected state UE between the first time and the second time.

[0091] Here, the base station does not release the connection in response to receiving the connection release request message. Here, the base station not releasing the connection can mean that the base station does not release the uplink and downlink information, for example, does not release the TRS and / or CSI-RS.

[0092] The embodiment of the present disclosure provides a processing method of a reference signal, executed by a base station, comprising: in response to receiving a connection release request message sent by a core network, performing the processing of releasing the connection of the UE, and continuing to send the reference signal according to the configuration of the reference signal of the connected state UE between the first time and the second time. In this way, the embodiment of the present disclosure can perform the processing of releasing the connection of the UE and not release the connection of the base station by receiving the connection release request message sent by the core network.

[0093] The embodiment of the present disclosure provides a processing method of a reference signal, executed by a base station of a first cell, comprising: in response to receiving a connection release request message sent by a base station where a second cell is located, performing the processing of releasing the connection of the UE, and continuing to send the reference signal according to the configuration of the reference signal of the connected state UE between the first time and the second time. In this way, the embodiment of the present disclosure can perform the processing of releasing the connection of the UE and not release the connection of the base station by receiving the connection release request sent by the base station where another cell is located.

[0094] In one embodiment, the processing of releasing the connection of the UE comprises one of the following but is not limited to:

[0095] sending a connection release message to the UE, wherein the connection release message indicates the UE to release the connection;

[0096] delaying sending a connection release message to the UE, wherein the connection release message indicates the UE to release the connection.

[0097] In an embodiment, the delaying of sending the release connection message to the UE can be: delaying until after the base station sends the availability indication of the reference signal.

[0098] An embodiment of the present disclosure provides a method for processing a reference signal, performed by a base station, comprising: in response to receiving a connection release request message sent by a core network, sending a release connection message to a UE after sending an availability indication of a reference signal.

[0099] For example, the base station receives a connection release request message sent by the core network, the connection release request message indicating that the base station releases the connection; then the base station does not release the connection of the base station; and the base station still continues to send the reference signal according to the configuration of the reference signal of the connected UE between the first time and the second time. In this embodiment, even if the UE has released the connection between the first time and the second time; but the base station does not release the connection, and can continue to send the reference signal in the original time-frequency domain position of sending the reference signal, until the base station notifies the UE of the availability indication of the reference signal and then releases the connection.

[0100] Thus, in the embodiments of the present disclosure, even if the UE has released the connection between the first time and the second time; but since the base station still does not release the connection between the first time and the second time, the base station can ensure the delivery of the air interface message such as the reference signal between the first time and the second time, so as to realize the synchronization of the transmission of the reference signal between the base station and the UE.

[0101] An embodiment of the present disclosure provides a method for processing a reference signal, performed by a base station, comprising: in response to triggering a reconfiguration process, performing a process of reconfiguring the UE, and continuing to send the reference signal according to the configuration of the reference signal of the connected UE between the first time and the second time.

[0102] Here, when the base station responds to the triggering of the reconfiguration process, the base station can not release the context message; for example, the base station does not release the TRS and / or CSI-RS.

[0103] In an embodiment, the reconfiguration process can be, but is not limited to, at least one of the following: reconfiguration process of a radio bearer, measurement, serving cell, and serving cell group.

[0104] In an embodiment, the performing of the process of reconfiguring the UE includes, but is not limited to, one of the following:

[0105] sending a reconfiguration message to the UE; wherein the reconfiguration message indicates that the UE reconfigures according to the reconfiguration message;

[0106] delaying sending the reconfiguration message to the UE, wherein the reconfiguration message indicates that the UE reconfigures according to the reconfiguration message.

[0107] In an embodiment, the delaying of sending the reconfiguration message to the UE can be: delaying until the base station sends the availability indication, and then sending the reconfiguration message to the UE.

[0108] For example, the base station triggers the reconfiguration process, and then the base station sends a reconfiguration message to the terminal, where the reconfiguration message indicates that the UE performs reconfiguration according to the content carried in the reconfiguration message; and the base station still continues to send the reference signal according to the configuration of the reference signal of the connected UE between the first time and the second time.

[0109] In this way, in the embodiments of the present disclosure, even if the UE releases the connection between the first time and the second time; but since the base station can still not release the connection between the first time and the second time, the base station can ensure the delivery of the reference signal between the first time and the second time, until the base station notifies the UE of the availability indication of the reference signal and then releases the reference signal. In this way, the synchronization of the reference signal transmission between the base station and the UE can be realized.

[0110] The method for processing the reference signal provided by the embodiments of the present disclosure is executed by the base station, and includes: in response to receiving a reestablishment request message sent by the UE, performing a process of reestablishing the connection of the UE, and continuing to send the reference signal according to the configuration of the reference signal of the connected UE between the first time and the second time.

[0111] 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 not releasing the connection can mean that the base station does not release the uplink and downlink information, for example, does not release the TRS and / or CSI-RS.

[0112] In an embodiment, the process of reestablishing the connection of the UE includes but is not limited to one of the following:

[0113] sending a reestablishment connection message to the UE; wherein the reestablishment connection message indicates that the UE reestablishes the connection;

[0114] delaying to send the reestablishment connection message to the UE, wherein the reestablishment connection message indicates that the UE reestablishes the connection.

[0115] In an embodiment, the delaying of sending the reestablishment connection message to the UE can be: delaying until the base station sends the availability indication, and then sending the reestablishment connection message to the UE.

[0116] The method for processing the reference signal provided by the embodiments of the present disclosure is executed by the base station, and includes: in response to receiving a reestablishment request message sent by the UE, sending a reestablishment connection message to the UE after sending an availability indication of the reference signal.

[0117] For example, the base station receives the reestablishment connection request sent by the UE, and the base station does not release the connection of the base station; the base station continues to send the reference signal according to the configuration of the reference signal of the connected UE between the first time and the second time. In this embodiment, the base station does not release the connection and does not perform the reestablishment connection. Although the UE has released the connection, the base station can continue to send the reference signal at the time-frequency domain position where the connected UE originally sends the reference signal until the base station notifies the UE of the availability indication of the reference signal, and then releases the connection and performs the reestablishment connection.

[0118] Therefore, in the embodiments of the present disclosure, even if the base station performs the reestablishment connection processing on the UE between the first time and the second time, and the UE has released the connection; since the base station does not release the connection between the first time and the second time, the base station can ensure the delivery of the reference signal, thereby realizing the synchronization of the reference signal transmission between the base station and the UE.

[0119] In some embodiments, the step S51 comprises one of the following:

[0120] In response to receiving the connection release request message, performing the processing of releasing the connection of the UE, and continuing to send the reference signal according to the configuration of the reference signal of the connected UE between the first time and the second time;

[0121] In response to triggering the reconfiguration processing, performing the processing of reconfiguring the UE, and continuing to send the reference signal according to the configuration of the reference signal of the connected UE before the predetermined time between the first time and the second time;

[0122] In response to receiving the reestablishment request message sent by the UE, performing the processing of reestablishing the connection of the UE, and continuing to send the reference signal according to the configuration of the reference signal of the connected UE between the first time and the second time.

[0123] In the embodiments of the present disclosure, when the base station receives the connection release request message sent by the core network or the base station of another cell, the base station can send the connection release message to the UE or delay sending the connection release message to the UE, so that the UE releases the connection. The base station can not release the connection between the first time and the second time, and the base station can continue to send the reference signal according to the configuration of the reference signal of the connected UE between the first time and the second time. Therefore, after the base station receives the connection release request message, the base station can ensure the delivery of the reference signal between the first time and the second time, and realize the synchronization of the reference signal between the base station and the UE. If the base station delays sending the connection release message to the UE until after sending the availability indication, the probability that the UE can receive the reference signal can be further ensured, and the synchronization accuracy between the base station and the UE is further improved.

[0124] Or, when the base station triggers reconfiguration, the base station can also send a reconfiguration message to the UE to make the UE perform reconfiguration processing; the base station can not release the connection between the first time and the second time, and the base station can continue to send the reference signal according to the configuration of the reference signal of the connected UE between the first time and the second time. In this way, even when the UE performs reconfiguration processing or has released the connection, the reference signal can still be received at the first time and the second time, and the synchronization of the reference signal between the base station and the UE is realized.

[0125] Or, when the base station receives the reconnection request message sent by the UE, the base station can send a reconnection message to the UE or delay sending the reconnection message to the UE to make the UE release the connection. The base station can not release the connection or reestablish the connection between the first time and the second time; the base station can continue to send the reference signal according to the configuration of the reference signal of the connected UE between the first time and the second time. In this way, after the base station receives the reconnection message, the reference signal can still be ensured to be sent between the first time and the second time, and the synchronization of the reference signal between the base station and the UE is realized. Moreover, if the base station delays sending the reconnection message to the UE until after the availability indication is sent, the probability that the UE can receive the reference signal can be further ensured, and the synchronization accuracy between the base station and the UE is improved.

[0126] It should be noted that those skilled in the art can understand that the method provided by the embodiments of the present disclosure can be executed alone or together with some methods in some methods or related technologies in the embodiments of the present disclosure.

[0127] The following method for processing a reference signal is applied to a UE, which is similar to the description of the method for processing a reference signal applied to a base station. For technical details not disclosed in the method for processing a reference signal applied to a UE, please refer to the description of the method for processing a reference signal applied to a base station, which will not be described in detail here.

[0128] As shown in Figure 6 , a method for processing a reference signal is provided, which is executed by a UE and includes:

[0129] Step S61: receiving a reference signal; wherein the reference signal is continuously sent by the base station according to the configuration of the reference signal of the connected UE before the second time.

[0130] In one embodiment, the reference signal is continuously sent by the base station according to the configuration of the reference signal of the connected UE between the first time and the second time. The first time is the time when the connected UE leaves; the first time is earlier than the second time.

[0131] In an embodiment, the reference signal comprises: a TRS and / or a CSI-RS.

[0132] In an embodiment, the second time is: a system message update time. In another embodiment, the second time is: a reference signal availability indication update time. Of course, in other embodiments, the second time can also be other specific times later than the first time; for example, the second time can also be a certain paging occasion of the non-connected state UE after the first time.

[0133] In an embodiment, the update period of the availability indication of the reference signal is multiplexed with the update period of the system message, i.e., the update period of the availability indication of the reference signal is the same as the update period of the system message.

[0134] In an embodiment, the availability indication comprises one of the following:

[0135] a state indication indicating an availability state of the configuration of the reference signal; wherein the availability state comprises: an available state and / or an unavailable state;

[0136] a state change indication indicating a change of the availability state of the configuration of the reference signal; wherein the state change indication comprises: the configuration of the reference signal is changed from the available state to the unavailable state; or, the configuration of the reference signal is changed from the unavailable state to the available state.

[0137] An embodiment of the present disclosure provides a reference signal processing method, executed by a UE, comprising: receiving an availability indication of a reference signal; wherein the availability indication is sent by a base station at a second time or any time after the second time; and the availability indication is used at least to determine an availability state of a configuration of the reference signal.

[0138] As shown in Figure 7 An embodiment of the present disclosure provides a reference signal processing method, executed by a UE, comprising:

[0139] Step S71: in response to listening to a signal strength of the reference signal being less than a strength threshold, listening to a synchronization signal block (SSB) for synchronization.

[0140] An embodiment of the present disclosure provides a reference signal processing method, executed by a UE, comprising: listening to a reference signal before a second time; and in response to listening to a signal strength of the reference signal being less than a strength threshold, listening to a synchronization signal block (SSB) for synchronization.

[0141] In an embodiment of the present disclosure, if the signal strength of the reference signal listened to by the UE is less than the strength threshold, it can be considered that the UE has not listened to the reference signal or has listened to a very weak reference signal; at this time, it can be fallen back to using the SSB for synchronization. In this way, the transmission synchronization between the UE and the base station between the first time and the second time can also be realized.

[0142] As Figure 8 shown, the embodiment of the present disclosure provides a reference signal processing method, executed by a UE, comprising:

[0143] Step S81: in response to determining that the availability state of the configuration of the reference signal is the unavailable state based on the system message, listening to the SSB for synchronization; or, in response to determining that the availability state of the configuration of the reference signal is changed from the available state to the unavailable state based on the system message, listening to the SSB for synchronization.

[0144] In the embodiment of the present disclosure, the availability indication of the reference signal can be carried in the system message; in this way, the availability state of the configuration of the reference signal can be determined to be the available state or the unavailable state by the UE checking the availability indication in the system message. For example, when the availability indication indicates that the configuration of the reference signal is in the available state or is changed from the available state to the unavailable state, the UE can also fallback to the way of using the SSB for synchronization. In this way, the transmission synchronization between the UE and the base station between the first time and the second time can also be achieved.

[0145] It should be noted that those skilled in the art can understand that the method provided by the embodiment of the present disclosure can be executed alone or together with some methods in some methods or related technologies in the embodiment of the present disclosure.
