The following describes in detail, with reference to the attached drawings, a status indication method, a device, a network side device and a readable storage medium provided by the embodiments of the present application through some embodiments and application scenarios thereof.
Referring to fig. 2, fig. 2 is a flowchart of a status indication method provided in an embodiment of the present application, where the method is performed by a first network side device, and the first network side device may be an access network device, such as a serving base station, a service Transmission-Reception Point (TRP), or the like. As shown in fig. 2, the method comprises the steps of:
step 21: the first network side equipment determines the sending state of the uplink positioning reference signal of the terminal.
Optionally, the sending state of the uplink positioning reference signal of the terminal may include suspending sending or resuming sending.
In some embodiments, the uplink positioning reference signal of the terminal may include, but is not limited to, a sounding reference signal (Sounding Reference Signal, SRS), and the like.
Step 22: the first network side equipment sends first indication information to the second network side equipment.
The first indication information is used for indicating the sending state of the uplink positioning reference signal of the terminal. For example, the first indication information may indicate that the transmission state of the uplink positioning reference signal of the terminal is suspension transmission, or the first indication information may indicate that the transmission state of the uplink positioning reference signal of the terminal is resumption transmission.
In some embodiments, the second network side device may be selected as a core network device, such as a location management function (Location Management Function, LMF), or the like. For example, after determining that the transmission state of the uplink positioning reference signal of the terminal is suspension transmission or restoration transmission, the serving base station/TRP may transmit first indication information to the LMF to indicate the transmission state of the uplink positioning reference signal of the terminal.
According to the state indication method, after the first network side device determines the sending state of the uplink positioning reference signal of the terminal, first indication information can be sent to the second network side device, and the first indication information is used for indicating the sending state of the uplink positioning reference signal of the terminal, wherein the sending state comprises sending suspension or sending resumption. Therefore, the related network side equipment can acquire the sending state of the uplink positioning reference signal of the terminal, so that the measurement failure of the uplink positioning reference signal caused by the fact that the second network side equipment sends a new measurement configuration when the terminal pauses to send the uplink positioning reference signal can be avoided, the reconfiguration of the uplink positioning reference signal caused by the measurement failure of the uplink positioning reference signal can be avoided, and the signaling overhead is reduced.
In this embodiment of the present application, the first network side device may determine a transmission state of an uplink positioning reference signal of the terminal according to configuration of the uplink positioning reference signal of the terminal and an uplink service state of the terminal.
Optionally, the first network side device may determine that the transmission state of the uplink positioning reference signal of the terminal is suspension transmission when the configuration of the uplink positioning reference signal of the terminal is that the uplink positioning reference signal is transmitted on a non-initial bandwidth and the uplink service state of the terminal is that the terminal initiates uplink data transmission. Or, the first network side device may determine that the transmission state of the uplink positioning reference signal of the terminal is resume transmission when the configuration of the uplink positioning reference signal of the terminal is that the uplink positioning reference signal is transmitted on a non-initial bandwidth and the uplink service state of the terminal is that the terminal completes the initiated uplink data transmission. In this way, when the terminal needs to initiate uplink data transmission, in order to ensure uplink data transmission, the terminal will suspend sending the uplink positioning reference signal on the non-initial bandwidth, and after the uplink data transmission is completed, the terminal will resume sending the uplink positioning reference signal on the non-initial bandwidth, so that the sending state of the uplink positioning reference signal of the terminal can be accurately determined by means of the configuration of the uplink positioning reference signal of the terminal and the uplink service state of the terminal.
In some embodiments, if the terminal configures an initial resource for uplink data transmission, the terminal may directly send uplink data on the initial resource, and in this case, after receiving the uplink data, the first network side device may learn that an uplink traffic state of the terminal is that uplink data transmission is initiated, and further determine that a sending state of an uplink positioning reference signal of the terminal is suspension sending.
In other embodiments, if the terminal does not configure the initial resource for uplink data transmission, the terminal may request the resource through a random access RA procedure and send uplink data based on the requested resource, and in this case, after receiving the resource request, the first network side device may learn that the uplink traffic state of the terminal is that uplink data transmission is initiated, and further determine that the sending state of the uplink positioning reference signal of the terminal is suspension sending.
Optionally, since the terminal generally needs a period of time to resume sending the uplink positioning reference signal after completing the initiated uplink data transmission, determining that the sending state of the uplink positioning reference signal of the terminal is resume sending may include: the method comprises the steps that under the condition that the first network side equipment configures uplink positioning reference signals of a terminal to be transmitted on a non-initial bandwidth, and the uplink service state of the terminal is that the terminal finishes initiated uplink data transmission, the transmission state of the uplink positioning reference signals of the terminal is determined to be recovery transmission at a first moment. The method comprises the steps of enabling a terminal to finish initiated uplink data transmission, wherein a time window with a preset length is arranged between a first time and a second time, and the second time is the time when the terminal finishes initiated uplink data transmission. The time window of the preset length can be set based on actual requirements, which is not limited.
Optionally, the uplink data transmission may include, but is not limited to, small data transmission (Small Data Transmission, SDT), and the like. For example, if the terminal sends uplink data through Configured Grant (CG) SDT, the terminal may send uplink data through preconfigured CG-SDT resources, and CG termination may be regarded as SDT transmission completion. Or if the terminal sends uplink data through RA-SDT, SDT may be initiated by sending a random access request message such as Msg1 on a preconfigured random access resource, and the base station sends rrc_inactive configuration (such as suspend) to the UE through RRCRelease message, which may be regarded as SDT transmission completion.
In some embodiments, the terminal in the rrc_inactive state may be configured to transmit the uplink positioning reference signal in a non-initial (non-initial) Bandwidth of the currently camping cell, such as a non-initial partial Bandwidth (BWP). After entering the rrc_inactive state, if the terminal needs to initiate SDT uplink service when sending an uplink positioning reference signal on the non-initial BWP, in order to ensure uplink data transmission, the terminal will suspend sending the uplink positioning reference signal and switch to initiate SDT on the initial BWP. After the uplink data transmission is completed, the terminal resumes sending the uplink positioning reference signal on the non-initial BWP.
In some embodiments, if the uplink positioning reference signal of the configured terminal is sent on the non-initial BWP, and the base station determines that the terminal initiates SDT on the initial BWP, the base station may determine that the sending status of the uplink positioning reference signal of the terminal is suspension. Further, if the base station determines that the terminal completes the SDT initiated, the base station may determine that the transmission state of the uplink positioning reference signal of the terminal is resume transmission, or determine that the transmission state of the uplink positioning reference signal of the terminal is resume transmission after a time window with a preset length, where the length of the time window may be set to, for example, a time (BWP switch time) required for switching BWP.
It should be noted that, the above-mentioned determining the sending state of the uplink positioning reference signal of the terminal and the indicated time are real-time, that is, the sending state of the uplink positioning reference signal of the terminal is determined in real time, and the indication is performed after the sending state is determined to be the suspension of sending or the resumption of sending. However, in addition to this, when the measurement request is received, the transmission state of the uplink positioning reference signal of the terminal may be determined, and the instruction may be made after the transmission state is determined to be the suspension transmission or the resumption of the transmission.
Optionally, before determining the transmission state of the uplink positioning reference signal of the terminal, the first network side device may receive a measurement request of the uplink positioning reference signal from the second network side device, so as to determine the transmission state of the uplink positioning reference signal of the terminal based on the measurement request, and instruct after determining that the transmission state is to suspend transmission or resume transmission.
Optionally, after the first indication information is sent to the second network side device, the first network side device may receive second indication information from the second network side device, where the second indication information is used to instruct the first network side device to suspend measurement of the uplink positioning reference signal, or instruct the first network side device to resume measurement of the uplink positioning reference signal, so as to perform a measurement operation under a condition that the terminal sends the uplink positioning reference signal. If the first indication information indicates that the sending state of the uplink positioning reference signal of the terminal is suspension sending, the corresponding second indication information indicates that the first network side equipment suspends measuring the uplink positioning reference signal; and if the first indication information indicates that the sending state of the uplink positioning reference signal of the terminal is restoration sending, the corresponding second indication information indicates that the first network side equipment restores to measure the uplink positioning reference signal.
Optionally, in the case that the transmission state of the uplink positioning reference signal of the terminal is suspension transmission, the first indication information may indicate that the transmission state of the uplink positioning reference signal of the terminal is suspension transmission, or the first indication information may indicate that suspension transmission of the uplink positioning reference signal of the terminal is true.
Optionally, when the sending state of the uplink positioning reference signal of the terminal is suspension sending, and the first indication information is sent through the first Message, the first indication information may be carried in a Message Type field of the first Message. Wherein the first message may be selected as the new message introduced in the present embodiment.
Optionally, in the case that the transmission state of the uplink positioning reference signal of the terminal is resume transmission, the first indication information may indicate that the transmission state of the uplink positioning reference signal of the terminal is resume transmission, or the first indication information may indicate that the resume transmission of the uplink positioning reference signal of the terminal is true.
Optionally, when the sending state of the uplink positioning reference signal of the terminal is resume sending and the first indication information is sent through the second Message, the first indication information may be carried in a Message Type field of the second Message. Wherein the second message may be selected as the new message introduced in the present embodiment.
In this embodiment of the present application, the manner in which the first network side device sends the first indication information may be multiplexing an existing message, or may be introducing a new message, such as an NRPPa message, which is not limited.
Optionally, in the case that the sending state of the uplink positioning reference signal of the terminal is suspension sending, the first network side device may send the first indication information to the second network side device through at least one of the following messages:
a positioning information failure (POSITIONING INFORMATION FAILURE) message;
a positioning information update (POSITIONING INFORMATION UPDATE) message;
the positioning information pauses (POSITIONING INFORMATION PAUSED) the message.
In some embodiments, a POSITIONING INFORMATION FAILURE/UPDATE message may be multiplexed, introducing first indication information indicating that the terminal's uplink positioning reference signal transmission is suspended, such as SRS transmission paused. The first indication information may indicate that the sending state of the uplink positioning reference signal of the terminal is suspension sending, for example, indication SRS transmission state: used. Alternatively, the first indication information may indicate that the suspension of the uplink positioning reference signal of the terminal is TRUE, such as indication SRS transmission paused: TRUE.
In some embodiments, a new POSITIONING INFORMATION PAUSED message may be introduced to send the first indication information. The first indication information may be carried in a Message Type field of the POSITIONING INFORMATION PAUSED Message, that is, the Message Type field in the POSITIONING INFORMATION PAUSED Message indicates that the sending state of the uplink positioning reference signal of the terminal is suspension sending. In addition, NRPPa Transaction ID fields may be included in the POSITIONING INFORMATION PAUSED message to indicate configuration information of the corresponding uplink positioning reference signals.
Optionally, in the case that the transmission state of the uplink positioning reference signal of the terminal is resume transmission, the first network side device may send the first indication information to the second network side device through at least one of the following messages:
a positioning information update (POSITIONING INFORMATION UPDATE) message;
location information recovery (POSITIONING INFORMATION RESUMED) message.
In some embodiments, POSITIONING INFORMATION UPDATE messages may be multiplexed, introducing first indication information indicating that the uplink positioning reference signal transmission of the terminal resumes, e.g., SRS transmission resumed. The first indication information may indicate that the transmission state of the uplink positioning reference signal of the terminal is recovery transmission, for example, indicated SRS transmission state: recovered. Alternatively, the first indication information may indicate that the recovery transmission of the uplink positioning reference signal of the terminal is TRUE, such as indication SRS transmission resumed: TRUE.
In some embodiments, a new POSITIONING INFORMATION RESUMED message may be introduced to send the first indication information. The first indication information may be carried in a Message Type field of the POSITIONING INFORMATION RESUMED Message, that is, the Message Type field in the POSITIONING INFORMATION RESUMED Message indicates that the sending state of the uplink positioning reference signal of the terminal is restoration sending. In addition, NRPPa Transaction ID fields may be included in the POSITIONING INFORMATION RESUMED message to indicate configuration information of the corresponding uplink positioning reference signals.
Referring to fig. 3, fig. 3 is a flowchart of a method for indicating a state according to an embodiment of the present application, where the method is performed by a second network side device, and the second network side device may be a core network device, such as an LMF. As shown in fig. 3, the method comprises the steps of:
step 31: the second network side equipment receives first indication information from the first network side equipment.
The first indication information is used for indicating a sending state of an uplink positioning reference signal of the terminal, and the sending state comprises sending suspension or sending resumption.
According to the state indication method, the second network side device can receive first indication information from the first network side device, wherein the first indication information is used for indicating the sending state of the uplink positioning reference signal of the terminal, and the sending state comprises sending suspension or sending resumption. Therefore, the related network side equipment can acquire the sending state of the uplink positioning reference signal of the terminal, so that the measurement failure of the uplink positioning reference signal caused by the fact that the second network side equipment sends a new measurement configuration when the terminal pauses to send the uplink positioning reference signal can be avoided, the reconfiguration of the uplink positioning reference signal caused by the measurement failure of the uplink positioning reference signal can be avoided, and the signaling overhead is reduced.
Optionally, after receiving the first indication information from the first network side device, the second network side device may perform a first operation, where the first operation may include at least one of:
transmitting measurement configuration information of an uplink positioning reference signal to third network side equipment;
measurement configuration information of the uplink positioning reference signal is not sent to the third network side equipment;
transmitting second indication information to third network side equipment; the second indication information is used for indicating the third network side equipment to suspend the measurement of the uplink positioning reference signal or indicating the third network side equipment to resume the measurement of the uplink positioning reference signal.
It should be noted that the third network side device is a relevant network side device for measuring the uplink positioning reference signal, for example, is a relevant base station/TRP for measuring the uplink positioning reference signal.

Example 1
In the first embodiment, the first network side device is taken as a service gNB/TRP, the second network side device is taken as an LMF, the third network side device includes the service gNB/TRP and an adjacent gNB/TRP, as shown in fig. 4, the corresponding status indication process may include:
step 401: the LMF obtains relevant information of the serving gNB/TRP and the adjacent gNB/TRP, obtains the positioning capability of the UE, and sends an NRPPa message such as a positioning information request (e.g. POSITIONING INFORMATION REQUEST) to the serving gNB/TRP to request SRS configuration information of the UE.
Step 402: the service gNB/TRP determines SRS configuration information.
Step 403: the serving gNB/TRP transmits SRS configuration information to the UE.
Step 404: the serving gNB/TRP transmits SRS configuration information to the LMF via an NRPPa message such as a location information response (e.g., POSITIONING INFORMATION RESPONSE).
Step 405: the UE enters the rrc_inactive state. Wherein, based on UE capabilities, the serving gNB/TRP may configure uplink positioning reference signals such as SRS to be transmitted on Non-initial bandwidth BWP.
Step 406: the UE initiates SDT in rrc_inactive state. If the UE transmits uplink data through the CG-SDT, the uplink data can be transmitted through pre-configuring CG-SDT resources; if the UE transmits uplink data through RA-SDT, SDT may be initiated by transmitting Msg1 on a preconfigured random access resource.
Step 407: if the uplink positioning reference signal of the UE is configured by the serving gNB/TRP, for example, SRS is sent on the Non-initial BWP, after the UE initiates SDT, it may be determined that the sending state of the uplink positioning reference signal of the current UE is suspension sending, and first indication information is sent to the LMF, where the first indication information is used to indicate that the sending state of the uplink positioning reference signal of the current UE is suspension sending. The sending manner of the first indication information may be shown in the foregoing, which is not described herein.
Step 408: if the LMF has transmitted the measurement configuration information and has not received the measurement report, transmitting second indication information to the relevant gNB/TRP, namely the serving gNB/TRP and the adjacent gNB/TRP, wherein the second indication information is used for indicating to suspend the measurement of the uplink positioning reference signal, and measuring after receiving first indication information indicating that the transmission state of the uplink positioning reference signal of the UE is the restoration transmission. The sending manner of the second indication information may be shown in the foregoing, which is not described herein.
If the LMF does not send the measurement configuration information, the LMF does not send new measurement configuration information until receiving the first indication information indicating that the sending state of the uplink positioning reference signal of the UE is to resume sending.
Step 409: the service gNB/TRP judges that the UE completes SDT and resumes the transmission of the uplink positioning reference signal. If the UE sends uplink data through the CG-SDT, the CG end can be regarded as the completion of SDT transmission; alternatively, if the UE sends uplink data through RA-SDT, the base station sends rrc_inactive configuration (e.g. suspend) to the UE through RRCRelease message, which may be regarded as SDT transmission completion.
Step 410: after the SDT transmission is completed, the service gNB/TRP may determine that the transmission state of the uplink positioning reference signal of the current UE is resume transmission, and send first indication information to the LMF for indicating that the transmission state of the uplink positioning reference signal of the current UE is resume transmission. The sending manner of the first indication information may be shown in the foregoing, which is not described herein.
Step 411: the LMF transmits second indication information to the relevant gNB/TRP, namely the serving gNB/TRP and the adjacent gNB/TRP, and the second indication information is used for indicating to resume measurement of the uplink positioning reference signals. The sending manner of the second indication information may be shown in the foregoing, which is not described herein.
If the LMF does not send the measurement configuration information, after receiving the first indication information indicating that the sending state of the uplink positioning reference signal of the UE is to resume sending, new measurement configuration information may be issued.

step 501: the LMF obtains relevant information of the serving gNB/TRP and the adjacent gNB/TRP, obtains the positioning capability of the UE, and sends an NRPPa message such as a positioning information request (e.g. POSITIONING INFORMATION REQUEST) to the serving gNB/TRP to request SRS configuration information of the UE.
Step 502: the service gNB/TRP determines SRS configuration information.
Step 503: the serving gNB/TRP transmits SRS configuration information to the UE.
Step 504: the serving gNB/TRP transmits SRS configuration information to the LMF via an NRPPa message such as a location information response (e.g., POSITIONING INFORMATION RESPONSE).
Step 505: the UE enters the rrc_inactive state. Wherein, based on UE capabilities, the serving gNB/TRP may configure uplink positioning reference signals such as SRS to be transmitted on Non-initial bandwidth BWP.
Step 506: the UE initiates SDT in rrc_inactive state. If the UE transmits uplink data through the CG-SDT, the uplink data can be transmitted through pre-configuring CG-SDT resources; if the UE transmits uplink data through RA-SDT, SDT may be initiated by transmitting Msg1 on a preconfigured random access resource.
Step 507: the LMF transmits NRPPa messages, such as measurement request (e.g., MEASUREMENT REQUEST) messages, including SRS configuration information, etc., to the relevant gNB/TRP, i.e., serving and neighbor gNB/TRP.
Step 508: if the uplink positioning reference signal of the UE configured by the serving gNB/TRP, such as SRS, is sent on the Non-initial BWP, it may be determined that the sending state of the uplink positioning reference signal of the current UE is suspension, and first indication information is sent to the LMF, where the first indication information is used to indicate that the sending state of the uplink positioning reference signal of the current UE is suspension. The sending manner of the first indication information may be shown in the foregoing, which is not described herein.
Step 509: the LMF transmits second indication information to the related gNB/TRP, namely the serving gNB/TRP and the adjacent gNB/TRP, and is used for indicating to suspend to measure the uplink positioning reference signal, and measuring after receiving the first indication information indicating that the transmission state of the uplink positioning reference signal of the UE is the restoration transmission. The sending manner of the second indication information may be shown in the foregoing, which is not described herein.
Step 510: the service gNB/TRP judges that the UE completes SDT and resumes the transmission of the uplink positioning reference signal. If the UE sends uplink data through the CG-SDT, the CG end can be regarded as the completion of SDT transmission; alternatively, if the UE sends uplink data through RA-SDT, the base station sends rrc_inactive configuration (e.g. suspend) to the UE through RRCRelease message, which may be regarded as SDT transmission completion.
Step 511: after the SDT transmission is completed, the service gNB/TRP may determine that the transmission state of the uplink positioning reference signal of the current UE is resume transmission, and send first indication information to the LMF for indicating that the transmission state of the uplink positioning reference signal of the current UE is resume transmission. The sending manner of the first indication information may be shown in the foregoing, which is not described herein.
Step 512: the LMF transmits second indication information to the relevant gNB/TRP, namely the serving gNB/TRP and the adjacent gNB/TRP, and the second indication information is used for indicating to resume measurement of the uplink positioning reference signals. The sending manner of the second indication information may be shown in the foregoing, which is not described herein.
