To describe technical solutions in examples of the disclosure more clearly, the following briefly introduces accompanying drawings needed for describing the examples. Apparently, the accompanying drawings in the following description show merely some examples of the disclosure, and those ordinarily skilled in the art may still derive other accompanying drawings from these accompanying drawings without creative efforts.
In order to make the objective, technical solutions and advantages of the disclosure clear, the implementations of the disclosure will be described further in detail below with reference to accompanying drawings.
Examples will be illustrated in detail here, and instances of which are represented in the accompanying drawings. When the following description refers to the accompanying drawings, the same number in the different accompanying drawings represents the same or similar elements unless otherwise indicated. The implementations described in the following examples do not represent all implementations consistent with the disclosure. On the contrary, they are merely examples of an apparatus and method consistent with some aspects of the disclosure as detailed in the appended claims.
Terms used in the disclosure are merely for the purpose of describing the particular examples, and are not intended to limit the disclosure. The singular forms “a”, “the” and “this” used in the disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It is to be further understood that a term “and/or” used in this text refers to and contains any or all possible combinations of one or more associated listed items.
It is to be understood that terms “first”, “second”, “third” and the like may be employed in the disclosure to describe various information, but these pieces of information should not be limited to these terms. These terms are merely used to distinguish the same type of information from one another. For example, in a case of not departing from the scope of the disclosure, first information may also be called second information, and similarly, the second information may also be called the first information. Depending on the context, for example, the word “if” as used here may be interpreted as “at the time of” or “when” or “in response to determining”.
Since the RTT information corresponds to a valid duration, and the RTT information is valid within the valid duration, the terminal starts to count the valid duration of the RTT information by taking an ending moment of a window corresponding to the system information as a starting moment (namely, an epoch time) from which the RTT information is valid. However, the network device cannot determine the starting moment of the RTT information received by the terminal, which causes that data cannot be transmitted normally.
Examples of the disclosure provide a method and an apparatus for reporting information, a device, and a storage medium, so as to facilitate a network device in determining a starting moment of a valid duration of RTT information received by a terminal, and ensuring accuracy of information reported by the terminal.
An example of the disclosure provides an information reporting manner, and the terminal reports the timing information of the RTT information to the network device, so as to facilitate the network device in determining the starting moment of the valid duration of the RTT information received by the terminal, and ensuring accuracy of the information reported by the terminal. Additionally, the timing information can indicate the valid duration of the RTT information to the network device, so as to facilitate the network device in executing subsequent data transmission based on the timing information, and ensuring the reliability of data transmission.
The following describes an application scenario of the disclosure.
The number of the terminals 10 is generally multiple, and one or more terminals 10 may be distributed in a cell managed by each network device 20. The terminal 10 may include various handheld devices, vehicle-mounted devices, wearable devices and computing devices with wireless communication functions, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), and so on. For the convenience of description, the devices mentioned above are collectively referred to as the terminal in the example of the disclosure.
The network device 20 is an apparatus deployed in an access network to provide a wireless communication function for the terminal 10. The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points and the like. In systems using different wireless access technologies, names of devices with network device functions may be different. For example, in a 5G new radio (NR) system, the device is called gNodeB or gNB. With evolution of a communication technology, the name “network device” may be changed. To facilitate the description, the above apparatuses that provide the wireless communication function for the terminal 10 are collectively referred to as the network device in the example of the disclosure. A connection may be established between the network device 20 and the terminal 10 through an air interface, so as to perform communication through the connection, including interaction of a signaling and data. The number of the network devices 20 may be multiple, and two adjacent network devices 20 may also communicate with each other in a wired or wireless manner. The terminal 10 may perform switching between the different network devices 20, that is, establish a connection with the different network devices 20.
In some examples, the transit device 30 may be a satellite, an unmanned aerial vehicle, or other devices having a transit function, which is not limited in the example of the disclosure.
In some examples, if the transit device 30 is the satellite, the communication system further includes a ground station, and the ground station performs wireless communication with the transit device 30 and the network device 20 respectively.
In the example of the disclosure, if the network device 20 needs to send a signal to the terminal 10, the network device first sends the signal to the transit device 30, and then the transit device 30 forwards the received signal to the terminal 10.
In some examples, the transit device 30 may use two transit modes, a transparent payload mode and a regenerative payload mode, respectively.
For example, if the transit mode of the transit device 30 is the transparent payload mode, after the network device 20 sends the signal to the transit device 30, the transit device 30 converts the frequency of the signal and then sends the signal to the terminal 10 without demodulating the signal.
For another example, if the transit mode of the transit device 30 is the regenerative payload mode, after the network device sends the signal to the transit device 30, the transit device 30 first demodulates the received signal, then encodes and modulates the signal again to obtain a regenerated signal, and sends the regenerated signal to the terminal 10.
In the example of the disclosure, transmission needs to be performed between the terminal 10 and the network device 20 via the transit device 30, while transmission between the terminal 10 and the network device 20 via the transit device 30 needs to consume a duration, and the duration is an RTT. For the RTT, the RTT includes two parts: a duration from the terminal 10 to the transit device 30 and a duration from the transit device 30 to the network device 20, respectively.
In some examples, the network device 20 sends RTT information to the terminal 10, and the RTT information indicates the RTT from the terminal 10 to the network device 20 via the transit device 30.
In some examples, the network device 20 sends the RTT information through system information.
In some examples, the RTT information includes first information and second information. The first information indicates the RTT from the transit device 30 to the network device 20, and the second information indicates an RTT from the terminal 10 to the transit device 30.
After acquiring the second information, the terminal 10 may determine a location of the transit device 30 according to the second information, and may calculate and determine the RTT from the terminal 10 to the transit device 30.
For example, the first information is common timing advance (TA), and the second information is ephemeris information.
The RTT information further has a valid duration, and the RTT information is valid within the valid duration of the RTT information.
In some examples, the valid duration is represented by a timing duration of a timer.
For example, the timer is a validity timer, or another timer, which is not limited in the example of the disclosure.
In the examples of the disclosure, the system information may further indicate a starting moment of the valid duration of the RTT information in an implicit indication manner, and the implicit indication manner is to take an ending moment of a time window for sending the RTT information as the starting moment of the valid duration of the RTT information. That is to say, the system information sent to the terminal by the network device implicitly indicates the starting moment of the valid duration of the RTT information, and specifically, the network device may take an ending location of a system information window (SI window) of the system information containing the ephemeris information and the common TA information as an epoch time (namely, a validity starting moment).
If the valid duration is represented by the timing duration of the timer, the ending moment of the window for sending the RTT information is taken as a starting moment of the timer.
In some examples, the terminal in the above examples is an Internet of Things (IOT) terminal, and the IOT device is a bandwidth reduction and low complexity UE (BL UE), a UE in a coverage enhancement (CE) mode, and a narrow band Internet of Things (NB-IOT) UE.
The “5G NR system” in the examples of the disclosure may also be referred to as a 5G system or an NR system, but a person skilled in the art may understand its meaning. The technical solutions described in the examples of the disclosure may be applicable to the 5G NR system, and may also be applicable to a subsequent evolution system of the 5G NR system.
Step 301: the terminal sends timing information to the network device, the timing information indicating a valid duration of RTT information, and the RTT information indicating a duration from the terminal to the network device via a transit device.
Step 302: the network device receives the timing information sent by the terminal.
In the example of the disclosure, the terminal actively sends the timing information to the network device, and informs the network device of the valid duration of the RTT information through the timing information; and after receiving the timing information, the network device may determine the valid duration of the RTT information indicated by the timing information.
After determining the valid duration of the RTT information of the terminal according to the timing information, the network device may reconfigure the RTT information for the terminal before the valid duration of the RTT information expires, so that the terminal continues to perform uplink transmission.
In the example of the disclosure, the network device carries the RTT information in system information, and broadcasts the system information; after receiving the RTT information, the terminal may determine the RTT information; and the system information further includes the valid duration of the RTT information, and the terminal determines the valid duration of the RTT information according to the system information.
In addition, the network device may further complete scheduling and release the terminal before the valid duration of the RTT information expires. In some examples, the terminal may be an IOT terminal.
In some examples, the timing information includes at least one of: a remaining duration within the valid duration, a duration that has lasted within the valid duration; or the valid duration.
(1) A remaining duration within the valid duration.
In the example of the disclosure, the terminal reports the timing information of the RTT information to the network device. When the terminal reports the timing information, the valid duration of the RTT information may have passed a certain duration. Thus, the timing information includes the remaining duration within the valid duration, so that the network device determines the remaining duration within the valid duration of the RTT information.
In some examples, the remaining duration within the valid duration may be seconds, milliseconds, the number of frames, the number of subframes, the number of time slots, or other numeric values.
If the valid duration is a non-integer, the remaining duration within the valid duration is rounded off, and the rounded-off duration is taken as the remaining duration within the valid duration. For example, during reporting, the duration may be rounded off by using a floor manner (a round down manner), and if the duration is 5.8 seconds, 5 seconds is reported.
In some other examples, the remaining duration within the valid duration may be represented as a combination of the seconds and the number of frames, or a combination of the seconds and the number of subframes, or a combination of the seconds and the number of time slots.
The integer part of the remaining duration within the valid duration is represented in seconds, and the non-integer part is represented in the number of frames, the number of subframes or the number of time slots.
It is to be noted that if a timer is used to represent the valid duration of the RTT information in the disclosure, the remaining duration within the valid duration is a remaining duration from the timer expires.
(2) A duration that has lasted within the valid duration.
In the example of the disclosure, the terminal reports the timing information of the RTT information to the network device. When the terminal reports the timing information, the valid duration of the RTT information may have passed a certain duration. Thus, the timing information includes the duration that has lasted within the valid duration, so that the network device determines the remaining duration within the valid duration of the RTT information according to a difference value between the configured valid duration and the duration that has lasted within the valid duration.
In some examples, the duration that has lasted within the valid duration may be seconds, milliseconds, the number of frames, the number of subframes, the number of time slots, or other numeric values.
In some other examples, the duration that has lasted within the valid duration may be represented as a combination of the seconds and the number of frames, or a combination of the seconds and the number of subframes, or a combination of the seconds and the number of time slots.
It is to be noted that if a timer is used to represent the valid duration of the RTT information in the disclosure, the duration that has lasted within the valid duration is a duration timed after the timer is started.
(3) The valid duration.
In the example of the disclosure, the terminal further reports the valid duration of the RTT information to the network device, so that the network device determines the valid duration of the RTT information used by the terminal, thus ensuring that the network device may determine the remaining duration of the RTT information based on the valid duration, and improving accuracy of the timing information reported by the terminal. By reporting the valid duration of the RTT information, it may be avoided that when the configured valid duration of the RTT information is changed in a network, the network device cannot determine the valid duration configuration of the RTT information adopted by the terminal.
It is to be understood that for reporting contents, the solution of reporting the valid duration may be implemented separately, and may be implemented in combination with the solution of reporting the remaining duration within the valid duration and the solution of reporting the duration that has lasted within the valid duration.
It is to be noted that the example of the disclosure is illustrated merely by taking an example that the terminal sends the timing information to the network device, but in another example, the terminal sends the timing information to a transit device, and then the transit device sends the received timing information to the network device.
It is to be noted that the steps performed by the terminal in the example of the disclosure may be separately implemented to form a new example, and the steps performed by the network device may be separately implemented to form a new example.
An example of the disclosure provides a method for reporting information, and a terminal reports timing information of RTT information to a network device, so as to facilitate the network device in determining a starting moment of a valid duration of the RTT information received by the terminal, and ensuring accuracy of information reported by the terminal. Additionally, the timing information can indicate the valid duration of the RTT information to the network device, so as to facilitate the network device in executing subsequent data transmission based on the timing information, and ensuring reliability of data transmission.
In some examples, based on the example shown in
Step 401: the terminal sends the timing information to the network device in a case that the network device indicates the starting moment of the RTT information in the implicit indication manner.
In the example of the disclosure, if the network device indicates the starting moment of the valid duration of the RTT information in the implicit indication manner, the terminal determines that the network device cannot accurately obtain the starting moment of the RTT information of the terminal at this moment, and at this moment, the terminal needs to send the timing information to the network device, so that the terminal informs the network device of the starting moment of the RTT information. For example, when the network device does not explicitly provide an epoch time (namely, the starting moment of the valid duration of the RTT information) in a system message, that is, the network device does not provide an SFN and subframe number corresponding to the epoch time, the terminal needs to send the timing information to the network device, so as to inform the network device.
In some examples, the starting moment is represented by adopting the epoch time (validity starting moment), or represented by adopting other manners, which is not limited in the example of the disclosure.
In some examples, the implicit indication manner is to determine an ending moment of a time window for sending the RTT information as the starting moment of the RTT information.
The network device sends the RTT information by means of system information (SI), the SI corresponds to the time window, and the implicit indication manner is to determine the ending moment of the time window corresponding to the SI for sending the RTT information as the starting moment of the valid duration of the RTT information.
In the example of the disclosure, the network device further receives the timing information sent by the terminal, and the timing information received by the network device is sent by the terminal to the network device in a case that the network device indicates the starting moment of the RTT information in the implicit indication manner.
In some examples, the terminal sends the timing information to the network device through a random access procedure.
In the example of the disclosure, the terminal is in a non-connected status, and at this time, the terminal needs to perform random access. At this time, the terminal needs to send the timing information to the network device, and thus the terminal may directly send the timing information to the network device through the random access procedure.
The random access procedure performed by the terminal may include any one of msgA (a random access message), msg3 (a random access message) or msg5 (a random access message), and thus, when sending the msgA, the msg3 or the msg5, the terminal may carry the timing information in the msgA, the msg3 or the msg5.
In some examples, the timing information is carried in a radio resource control (RRC) signaling, or the timing information is carried in a media access control control element (MAC CE) signaling.
In some examples, the timing information is carried in at least one of a connection establishment request, a connection restoration request or a connection reestablishment request in the random access procedure.
If the timing information is carried in the RRC signaling, the timing information is carried in at least one of the connection establishment request, the connection restoration request or the connection reestablishment request in the random access procedure.
In some examples, if the timing information is carried in the MAC CE signaling, a logical channel prioritizationn (LCP) of the MAC CE signaling carrying the timing information is higher than that of logical channel data, and is lower than that of up link common control channel (UL-CCCH) data or that of the MAC CE signaling carrying a cell-radio network temporary identifier (C-RNTI).
The LCP of the MAC CE signaling carrying the timing information is higher than a priority of a buffer status report (BSR) or lower than a priority of a power headroom report (PHR).
It is to be noted that, when the terminal sends the timing information to the network device through the random access procedure, a random access procedure triggered through an on-demand SI request is not included.
In addition, in the example of the disclosure, the network device may further send, to the terminal, indication information for indicating whether the terminal is allowed to send the timing information through the random access procedure. If the indication information indicates that the terminal is allowed to send the timing information through the random access procedure, the terminal may perform the foregoing procedure of sending the timing information through the random access procedure. However, if the indication information indicates that the terminal is prohibited from sending the timing information through the random access procedure, the terminal cannot execute the foregoing procedure of sending the timing information through the random access procedure.
In some other examples, the terminal may further send the timing information in the following cases.
(1) The terminal sends the timing information to the network device in a case that the timing information is not sent through the random access procedure.
In the example of the disclosure, if the terminal does not send the timing information through the random access procedure, the terminal sends the timing information to the network device after being in a connected status subsequently.
(2) The terminal sends the timing information to the network device in a case that new RTT information configured by the network device is acquired.
In the example of the disclosure, the network device may further re-configure the new RTT information for the terminal, and if the terminal acquires the new RTT information configured by the network device, the terminal needs to send the timing information to the network device.
In some examples, the network device configures the new RTT information for the terminal by broadcast.
(3) The terminal sends the timing information to the network device in a case that the valid duration is reset.
In the example of the disclosure, the valid duration of the RTT information received by the terminal is reset, that is, the terminal re-times the valid duration of the RTT information, and in a case of determining that the valid duration is reset, the terminal sends the timing information to the network device.
It is to be noted that the example of the disclosure is illustrated merely by taking an example of sending the timing information to the terminal in the foregoing three situations. In another example, a specific moment when the terminal sends the timing information is illustrated.
In some examples, the terminal sends the timing information to the network device at any moment within the valid duration.
In the example of the disclosure, after determining in the above manner that the timing information needs to be sent to the network device, the terminal sends the timing information to the network device at any moment within the valid duration of the RTT information.
In some examples, if the valid duration is timed by using a timer, the timing information is sent to the network device at any moment before the timer expires.
In some other examples, the terminal sends the timing information to the network device within a preset duration before the valid duration expires, where the preset duration is less than the valid duration.
In the example of the disclosure, the preset duration is set in the terminal, and the terminal may send the timing information to the network device within the preset duration before the valid duration expires.
In some examples, the terminal sends the timing information to the network device at a preset moment within the preset duration before the valid duration expires.
In some examples, the preset duration is configured by the network device, or configured in other manners.
For example, the network device may configure a threshold, and reporting may be triggered within the threshold before the valid duration expires.
According to the method provided by the example of the disclosure, the terminal reports the timing information of the RTT information to the network device, so as to facilitate the network device in determining the starting moment of the valid duration of the RTT information received by the terminal, and ensuring accuracy of the information reported by the terminal. Additionally, the timing information can indicate the valid duration of the RTT information to the network device, so as to facilitate the network device in executing subsequent data transmission based on the timing information, and ensuring reliability of data transmission.
In some examples, based on the example shown in
Step 501: the network device sends the indication information to the terminal, the indication information instructing the terminal to send the timing information to the network device.
Step 502: the terminal receives the indication information sent by the network device.
Step 503: the terminal sends the timing information to the network device in response to the indication information.
Step 504: the network device receives the timing information sent by the terminal in response to the indication information.
In the example of the disclosure, the terminal receives the indication information sent by the network device, the indication information instructing the terminal to send the timing information to the network device, the terminal sends the timing information to the network device in response to the indication information, and then the network device receives the timing information sent by the terminal.
In some examples, the indication information is carried in system information. That is, the network device carries the indication information in the system information, and the indication information may be sent to the terminal in a process that the network device broadcasts the system information.
It is to be noted that, in the foregoing example, the terminal sends the timing information to the network device when being in the connected status. If the terminal sends the timing information without an uplink resource, the terminal needs to trigger SR or RACH first, and then sends the timing information after acquiring the uplink resource.
The time when the terminal sends the timing information and the content of the timing information are already described in the aforementioned examples, and are not repeated here.
According to the method provided by the example of the disclosure, the terminal reports the timing information of the RTT information to the network device, so as to facilitate the network device in determining the starting moment of the valid duration of the RTT information received by the terminal, and ensuring accuracy of the information reported by the terminal. Additionally, the timing information can indicate the valid duration of the RTT information to the network device, so as to facilitate the network device in executing subsequent data transmission based on the timing information, and ensuring reliability of data transmission.
In some examples, the terminal may send the timing information according to request information sent by the network device. Referring to
Step 601: the network device sends the request information to the terminal.
Step 602: the terminal receives the request information sent by the network device, the request information being configured to request the terminal to send the timing information.
In the example of the disclosure, if the network device needs to acquire the timing information of the terminal, the network device sends the request information to the terminal, and after receiving the request information, the terminal determines that the network device needs to acquire the timing information.
In some examples, the request information is carried in a terminal dedicated signaling.
Step 603: the terminal sends response information to the network device in response to the request information, the response information including the timing information.
In the example of the disclosure, after receiving the request information, the terminal sends the response information including the timing information to the network device in response to the request information, which may also be understood as follows: after receiving the request information sent by the network device, the terminal returns the timing information to the network device by means of feedback information of the request information.
In some examples, the request information is RRC information, MAC CE information or PDCCH information. Correspondingly, the response information returned by the terminal is RRC information or MAC CE information.
It is to be noted that the example of the disclosure is illustrated merely by taking an example that the network device sends the request information to the terminal. In another example, the network device may further determine whether to send the request information based on capability information sent by the terminal.
In the example of the disclosure, the terminal sends the capability information to the network device, the capability information indicating whether the terminal supports sending the timing information; and the network device receives the capability information sent by the terminal, and sends the request information based on the capability information.
If the capability information returned by the terminal indicates that the terminal does not support sending the timing information, the network device does not execute step 601 above and the terminal does not execute the subsequent steps. If the capability information returned by the terminal indicates that the terminal supports sending the timing information, the network device may execute step 601, and the terminal may also execute the subsequent steps 602-603.
The content of the timing information has already been described in the aforementioned examples, and is not repeated here.
According to the method provided by the example of the disclosure, the terminal informs, by means of the capability information, the network device whether the terminal supports sending the timing information, so that the network device may determine whether to actively request to acquire the timing information of the terminal, thus improving communication efficiency.
Based on the example shown in
Step 701: the network device configures a target period to the terminal.
Step 702: the terminal receives the target period configured by the network device.
Step 703: the terminal sends the timing information to the network device according to the target period.
In the example of the disclosure, the network device may configure the target period for the terminal; after receiving the target period, the terminal may determine that the timing information needs to be periodically sent to the network device; and thus, the terminal periodically sends the timing information to the network device according to the target period.
The target period is 10 milliseconds (ms), 20 ms, or other numeric values.
It is to be noted that the example of the disclosure is merely illustrated by taking an example that the network device configures the target period for the terminal. Steps 701-702 above are optional steps. In another example, steps 701-702 may not be performed, and the terminal directly sends the timing information to the network device according to the target period.
In the example of the disclosure, the target period may be appointed by a communication protocol, or determined by the terminal, which is not limited in the example of the disclosure.
The content of the timing information has already been described in the aforementioned examples, and is not repeated here.
Based on the example shown in
Step 801: the network device sends the preset duration to the terminal, the preset duration being less than the valid duration.
Step 802: the terminal receives the preset duration sent by the network device.
Step 803: the terminal sends a timing duration to the network device within the preset duration before the valid duration expires.
In the example of the disclosure, the network device configures the preset duration for the terminal, and instructs the terminal, through the preset duration, to send the timing information within the preset duration before the valid duration expires. Thus, after receiving the preset duration sent by the network device, the terminal sends the timing duration to the network device within the preset duration before the valid duration expires. It may also be understood that the network device configures a trigger event for the terminal by means of the preset duration, if the terminal determines to reach the preset duration before the valid duration expires, event triggering is determined, and the timing information needs to be sent to the network device.
It is to be noted that the example of the disclosure is merely illustrated by taking an example that the network device configures the preset duration for the terminal. Steps 801-802 above are optional steps. In another example, steps 801-802 may not be performed, and the terminal directly sends the timing information to the network device according to the preset duration.
In the example of the disclosure, a target period may be appointed by a communication protocol, or determined by the terminal, which is not limited in the example of the disclosure.
The content of the timing information has already been described in the aforementioned examples, and is not repeated here.
Based on the example shown in
Step 901: the network device sends the terminal dedicated signaling to the terminal.
Step 902: the terminal receives the terminal dedicated signaling sent by the network device, and sends the timing information to the network device.
In the example of the disclosure, the network device sends the terminal dedicated signaling to the terminal, and instructs the terminal, through the terminal dedicated signaling, to send the timing information to the network device. Thus, after receiving the terminal dedicated signaling, the terminal determines that the timing information needs to be sent to the network device.
In some examples, the terminal sends the timing information through a UE assistance information message.
In some examples, the terminal receives the terminal dedicated signaling sent by the network device, and sends the timing information in the following cases.
(1) The timing information is sent to the network device in a case that the timing information is not sent through a random access procedure.
(2) The timing information is sent to the network device in a case that new RTT information configured by the network device is acquired.
(3) The timing information is sent to the network device in a case that the valid duration is reset.
In some examples, the terminal sends the timing information to the network device at any moment within the valid duration.
In some other examples, the terminal sends the timing information to the network device within the preset duration before the valid duration expires.
The steps performed in the example of the disclosure are similar to the steps performed in the example shown in
It is to be noted that the example of the disclosure is illustrated merely by taking an example that the network device sends the terminal dedicated signaling to the terminal. In another example, the network device may determine whether to send the terminal dedicated signaling based on capability information sent by the terminal.
In the example of the disclosure, the terminal sends the capability information to the network device, the capability information indicating whether the terminal supports sending the timing information; and the network device receives the capability information sent by the terminal, and sends the terminal dedicated signaling based on the capability information.
If the capability information returned by the terminal indicates that the terminal does not support sending the timing information, the network device does not execute step 901 above and the terminal does not execute the subsequent steps performed by the terminal. If the capability information returned by the terminal indicates that the terminal supports sending the timing information, the network device may execute step 901, and the terminal may also execute the subsequent steps 902-903.
The content of the timing information has already been described in the aforementioned examples, and is not repeated here.
According to the method provided by the example of the disclosure, the terminal informs, by means of the capability information, the network device whether the terminal supports sending the timing information, so that the network device may determine whether to actively request to acquire the timing information of the terminal, thus improving communication efficiency.
Based on the example shown in
In some examples, the terminal sends the timing information to the network device in the case that the new RTT information configured by the network device is acquired.
In the example of the disclosure, in the case that the terminal acquires the new RTT information configured by the network device, the terminal determines that the timing information needs to be sent to the network device, and the network device may receive the timing information sent by the terminal.
In some other examples, the terminal sends the timing information to the network device in the case that the valid duration is reset.
In the example of the disclosure, the valid duration of the RTT information received by the terminal is reset, that is, the terminal re-times the valid duration of the RTT information, and in a case of determining that the valid duration is reset, the terminal sends the timing information to the network device.
As mentioned above, the terminal may send the timing information to the network device. In addition, the terminal may further cancel reporting of the timing information to the network device, that is, the terminal may cancel sending of the timing information, which specifically includes any one of the following cases.
(1) Sending of the timing information to the network device is canceled in a case that the RTT information is acquired through the terminal dedicated signaling.
In the example of the disclosure, after acquiring the RTT information through the terminal dedicated signaling, the terminal may further determine the starting moment of the valid duration of the RTT information according to the terminal dedicated signaling. Since the terminal dedicated signaling is sent by the network device, the network device also learns the starting moment of the valid duration of the RTT information, and thus, the terminal does not need to send the timing information, and cancels sending of the timing information to the network device.
(2) The timing information is not sent to the network device after the RTT information is acquired through the terminal dedicated signaling.
In the example of the disclosure, after acquiring the RTT information through the terminal dedicated signaling, the terminal may further determine the starting moment of the valid duration of the RTT information according to the terminal dedicated signaling. Since the terminal dedicated signaling is sent by the network device, the network device also learns the starting moment of the valid duration of the RTT information, and thus, the terminal does not send the timing information to the network device subsequently.
(3) The timing information is not sent to the network device after the RTT information is acquired through the terminal dedicated signaling and before the new RTT information configured by the network device is acquired.
In the example of the disclosure, after acquiring the RTT information through the terminal dedicated signaling, the terminal may further determine the starting moment of the valid duration of the RTT information according to the terminal dedicated signaling. Since the terminal dedicated signaling is sent by the network device, the network device also learns the starting moment of the valid duration of the RTT information, and thus, the timing information is not sent to the network device after the RTT information is acquired through the terminal dedicated signaling and before the new RTT information configured by the network device is acquired.
(4) Sending of the timing information to the network device is canceled in a case that a canceling instruction sent by the network device is received.
In the example of the disclosure, the network device may further send the canceling instruction to the terminal to inform the terminal to cancel sending of the timing information, and thus, the terminal cancels sending of the timing information to the network device in the case of receiving the canceling instruction.
(5) Sending of the timing information to the network device is canceled in a case that the RTT information is acquired in an on-demand manner.
In the example of the disclosure, the terminal may request to acquire the RTT information configured by the network device in the on-demand manner. In this case, the network device may determine the starting moment of the valid duration of the RTT information of the terminal, and thus, the terminal does not need to send the timing information to the network device, and cancels the determined sending of the timing information to the network device.
According to the method provided by the example of the disclosure, the terminal may cancel sending of the timing information to the network device, so as to ensure that the terminal does not send the timing information in a case of not sending the timing information to the network device, thus saving signaling overheads and improving transmission efficiency.
