The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings by using some embodiments and application scenarios thereof.

As shown in fig. 2, a flow chart of a data transmission method 200 provided in an exemplary embodiment of the present application is illustrated, and the method 200 may be executed by, but not limited to, a terminal, and specifically may be executed by hardware and/or software installed in the terminal. In this embodiment, the method may include at least the following steps.

S210, in the positioning measurement process, the first terminal starts a target timer when receiving uplink scheduling information sent by the network side device.

The network side equipment comprises a base station and/or a core network node. The uplink scheduling information is used for the network side device (e.g., the base station) to notify a target Configuration Grant (CG) to the first terminal, that is, the uplink scheduling information will be valid at the first time. In other words, after the network side device performs the authorization-free configuration (that is, the target CG configuration) according to the first time, the effective time of the target CG is notified to the first terminal through the uplink scheduling information, so that the first terminal can transmit the positioning data and the like within the effective time of the authorization-free configuration, and thus, the authorization-free configuration can be performed for a specific service type (for example, a positioning measurement service, a service requiring an ultrafast response time, and the like) by accurately obtaining different service types on the first terminal, so that the first terminal can report the service data according to the authorization configuration corresponding to the specific service type, thereby avoiding the occurrence of problems of service transmission failure and the like caused by that the first terminal can only perform data transmission according to the preconfigured scheduling resources, and improving the wireless communication performance.

The target CG may be a configuration grant Type 1 (CG Type 1, cg1), a configuration grant Type 2 (CG Type 2, cg2), or the like, wherein the CG1 may be configured by a Radio Resource Control (RRC) layer through higher layer signaling, such as ConfiguredGrantConfig; the CG2 may indicate activation and deactivation of the uplink unlicensed by Downlink Control Information (DCI), and a required parameter of the CG2 is configured by IE ConfiguredGrantConfig.

The first terminal starts the target timer to ensure that the positioning data can be sent at the effective time of the target CG, and based on this, the timing length of the target timer is determined based on the first time, for example, the timing length of the target timer may be the first time, or may be smaller than the first time, which is not limited herein.

And S220, when the target timer is overtime, the first terminal uses the uplink scheduling resource configured by the target CG to send positioning data.

In this embodiment, in the positioning measurement process, the network side device notifies the first terminal of the effective time of the CG, so that the first terminal can send the positioning data based on the scheduling resource configured by the CG. Therefore, on the one hand, compared with the problems of service processing failure and large data transmission delay caused by that the preconfigured scheduling resources in the related art are directed to all services on the terminal and the service types are not distinguished, the technical scheme provided by the embodiment can accurately perform corresponding authorization-free configuration on the service types, thereby avoiding the problems of service transmission failure and the like caused by that the first terminal can only perform data transmission according to the preconfigured scheduling resources, reducing data transmission delay and improving wireless communication performance.

On the other hand, in this embodiment, the effective time of the target CG is further notified to the first terminal in advance, so that the first terminal may send uplink data based on the uplink scheduling resource configured by the target CG, and therefore, a delayed uplink (delayed-MO) is introduced into the positioning measurement procedure to provide sufficient response time for the positioning measurement service, thereby reducing the positioning data transmission delay and improving the wireless communication performance.

As shown in fig. 3a, a flow chart of a data transmission method 300 provided for an exemplary embodiment of the present application is schematic, and the method 300 may be, but is not limited to be, executed by a terminal, and in particular may be executed by hardware and/or software installed in the terminal. In this embodiment, the method may include at least the following steps.

S310, in the positioning measurement process, the first terminal starts a target timer when receiving uplink scheduling information sent by the network side device.

The uplink scheduling information is used for notifying the first terminal that a target CG is about to take effect at a first time, and the timing length of the target timer is determined based on the first time.

It can be understood that, as a possible implementation manner, in addition to the implementation process of S310 with reference to the related description in the foregoing method embodiment 200, in order to ensure that the first terminal and the network-side device understand the first time consistently and reduce the data transmission delay, before receiving the uplink scheduling information sent by the network-side device, the first terminal may further perform any one of the following (1) or (2).

(1) A first terminal sends a first positioning request (LCS MO request) to network side equipment; the first positioning request carries the first time, and the first time is used for indicating relevant time information during positioning measurement. In this case, the network side device may immediately initiate an authorization-exempt configuration (grant) based on the first time when receiving the first positioning request, or carry the uplink scheduling information in an RRC reconfiguration (RRC reconfiguration) message, so that the authorization-exempt configuration becomes effective at the first time through the first terminal.

(2) The first terminal receives a second positioning request sent by the network side equipment; the second positioning requests respectively carry the first time, and the first time is used for indicating relevant time information during positioning measurement. The manner of acquiring the first time by the network side device may be directly reported by the terminal, issued by the core network node through signaling, agreed by a protocol, and the like, which is not limited herein.

In the two foregoing manners, (1) a first terminal initiates a positioning measurement procedure, and notifies the network side device of the first time, where for the first terminal, the first time may be agreed by a protocol, issued by a base station, configured by a higher layer, and the like. (2) The network side device initiates a positioning measurement procedure and notifies the first terminal of the first time. That is, in this embodiment, the first terminal and the network side device are mutual.

It should be noted that, in this embodiment, the first time may be used to indicate relevant time information in positioning measurement, in addition to being an effective time of the target CG. For example, the relevant time information indicated by the first time may include at least one of the following (1) - (11).

(1) And the first terminal acquires the moment of the positioning result.

(2) The first terminal acquires a time of a positioning measurement interval (gap).

(3) And the first terminal starts the time of the positioning measurement process. Also understood as the time when the first terminal sends a positioning request, etc.

(4) And the network side equipment informs the first terminal of the time of positioning measurement.

(5) And the network side equipment acquires the positioning result from the first terminal.

(6) And the first terminal acquires the latest moment of the positioning result.

(7) The first terminal obtains the latest moment of a positioning measurement interval.

(8) And the first terminal starts the latest moment of the positioning measurement process.

(9) And the network side equipment informs the first terminal of the latest moment for positioning measurement.

(10) And the network side equipment acquires the latest moment of the positioning result from the first terminal.

(11) And the first terminal reports the period (or frequency) of the positioning result or the measurement result. For example, the positioning result or measurement result is reported every two hours.

As described in the foregoing (1) to (11), the first time may be a time point, or may also be a time period, for example, when the first time is the time period, the first terminal needs to obtain a positioning result before the first time, obtain a positioning measurement interval, and report the positioning result or the measurement result, that is, as described in the foregoing (6) to (11).

In another possible implementation manner, the Uplink scheduling information may further include a Radio Bearer (RB) identifier and a logical Channel identifier, where a logical Channel corresponding to the logical Channel identifier has a specified priority, such as a high priority, and the logical Channel may be a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), and the like. Therefore, the first terminal can report the positioning data directly based on the RB identifier and the logical channel identifier under the condition of not sending the positioning request. For example, other NAS messages are sent using a Radio signaling Bearer (SRB) 2, and positioning messages are sent using an SRB 4. Wherein, a cause of uplink transmission of a Non Access Stratum (NAS) through the RRC increases a cause value as positioning, and then the SRB4 bearer can be adopted based on the RRC determination.

As another possible implementation manner, for a first terminal in an inactive (inactive) state, the network side device may send a specified preamble (preamble index) to the first terminal, so that the first terminal may send a first positioning request to the network side device based on the specified preamble, where the specified preamble is dedicated for reporting a positioning measurement result, and the specified preamble is used to apply for a logical channel identifier and an RB identifier having an association relationship with the specified preamble to the network side device, then, the network side device may find the logical channel identifier and the RB identifier corresponding to the specified preamble based on the association relationship when receiving the specified preamble, and send the logical channel identifier and the RB identifier to the first terminal through uplink scheduling information for the first terminal to perform positioning data reporting, so that by introducing a new SRB and a processing procedure in a positioning measurement procedure, transmission delay can be effectively reduced, and positioning data reporting performance can be improved.

Optionally, the aforementioned designated preamble may be transmitted through DCI (such as DCI format 1A or DCI) and/or RRC (RACH-configdetermined) signaling. Therefore, even for the first terminal in the inactive state, the network side device can use the designated preamble, so that the first terminal in the inactive state can notify the network side device through the designated preamble to apply for the RB identifier and the logical channel identifier associated with the designated preamble, and report the positioning data based on the RB identifier and the logical channel identifier.

It will be appreciated that the association relationship with respect to the foregoing may be: the network side equipment associates the positioning service, the designated lead code, the RB identifier and the logic channel identifier in advance, so that the designated lead code can be used for a special positioning reporting process of a single terminal.

In addition, the aforementioned RB identity is a location specific identifier that can be used for high priority processing of uplink location data. In other words, the first terminal and/or the network side device may determine whether the data (or information) to be transmitted is the positioning data based on the RB identifier, for example, in a case that the data to be transmitted includes the RB identifier, the data to be transmitted is the positioning data.

In one implementation, the RB identity may be associated with the target CG for preferential transmission of positioning data.

S320, when the target timer is overtime, the first terminal sends the positioning data using the uplink scheduling resource configured by the target CG.

As a possible implementation manner, in addition to referring to the related description in the foregoing method embodiment 200, when the uplink scheduling information includes an RB identifier and a logical channel identifier, the first terminal may send uplink positioning data in the uplink scheduling resource configured based on the CG target, and the radio bearer corresponding to the RB identifier and the logical channel corresponding to the logical channel identifier.

And S330, preferentially sending the positioning data under the condition that the positioning data and the first uplink data have resource conflict.

The priority of the first uplink data is lower than that of the positioning data, and the first uplink data is other uplink data except the positioning data. The first uplink data may be Enhanced Mobile Broadband (eMBB) data or other services without ultra-reliable and low latency (URLLC) requirements, which is not limited herein.

Further, in consideration of reasonable configuration of resources, when performing positioning procedure configuration non-periodically or non-immediately, the network side device may transmit the positioning data when the second uplink data and the positioning data are preempted by resources, and simultaneously notify the second terminal to cancel transmission of the second uplink data (similar to a URLLC procedure).

That is, when the network-side device (e.g., a base station) schedules the positioning data and the second uplink data at the same time and the second uplink data and the positioning data are preempted by resources, the positioning data is transmitted, and the second terminal is notified to cancel the transmission of the second uplink data. Optionally, the second uplink data may be eMBB data or other services without URLLC requirements, and correspondingly, the second terminal may be an eMBB terminal or a terminal carrying other services without URLLC requirements.

Based on the foregoing description of the method embodiment 300, the data transmission method 300 provided in the embodiment of the present application is further described below with reference to fig. 3b, fig. 3c, example 1, and example 2. Wherein, the network side device is assumed to comprise a base station (gNB) and a core network node (LMF).

Example 1

(1) As shown in fig. 3b, in the case that the UE is in the connected state, the UE sends a location request carrying the first time T to the LMF to notify the LMF to initiate a location procedure.

(2) The LMF informs the gNB of T through a positioning request.

(3) The gNB sends T to the UE through the RRC reconfiguration message, and notifies the UE that the uplink scheduling resource configured with the CG1 is in effect at a specific time (that is, the uplink scheduling resource configured by the CGI is in effect at time T).

(4) And the UE starts a target timer and transmits the positioning data on the configured uplink resource under the condition that the target timer is overtime.

In this example 1, for the positioning measurement procedure sent by the terminal, the terminal notifies the network side device of the first time, notifies the network side of the relevant time information during positioning measurement, and then the network side device allocates uplink non-authorization to the terminal at a specific time, so that the terminal can send positioning data in the uplink scheduling resource configured without authorization, thereby ensuring smooth operation of the positioning measurement service and ensuring wireless communication performance.

Example 2

(1) As shown in fig. 3c, when the UE is in the inactive state, the gNB notifies the UE of the location-specific preamble under inactive (i.e. the aforementioned designated preamble) through DCI 1A or RRC signaling RACH-configDedicated.

(2) And the UE initiates a positioning process by using the positioning dedicated preamble index, and carries the first time T in a positioning communication protocol (LPP) message to the LMF.

(3) LMF gives T to gNB.

(4) The base station associates and positions the UE, the logical channel ID and the RB identification, and informs the UE of using the uplink scheduling resource CG1 at a specific moment together with the uplink scheduling information, meanwhile, the base station informs other UEs that the uplink scheduling resource is used by the positioned UE, and other UEs cancel the uplink scheduling.

(5) And the UE receives the CG1 and the T, starts a positioning process and reports positioning data by using the CG1 at the moment T.

In this example 2, for a terminal in an inactive state, a network-side device directly issues a dedicated designated preamble for positioning, the terminal initiates a positioning process based on the designated preamble to notify the network-side of relevant time information during positioning measurement, and the network-side device allocates uplink non-authorization to the terminal at a specific time, so that the terminal can send positioning data in an uplink scheduling resource configured without authorization.

As shown in fig. 4, a flow chart of a data transmission method 400 provided in an exemplary embodiment of the present application is illustrated, where the method 400 may be executed by, but not limited to, a network-side device, and specifically may be executed by hardware and/or software installed in the network-side device. In this embodiment, the method may include at least the following steps.

S410, in the positioning measurement process, the network side equipment sends uplink scheduling information to a first terminal, wherein the uplink scheduling information is used for informing the first terminal that a target CG is about to take effect at a first time;

s420, the network side device receives positioning data, where the positioning data is sent by using an uplink scheduling resource configured by the target CG by the first terminal after a target timer expires, and a timing length of the target timer is determined based on the first time.

In a possible implementation manner, before the step of sending the uplink scheduling information to the first terminal, the method further includes any one of the following: the network side equipment receives a first positioning request sent by the first terminal; the network side equipment sends a second positioning request to the first terminal; the first positioning request and the second positioning request carry first time, and the first time is used for indicating relevant time information during positioning measurement.

In another possible implementation manner, the relevant time information includes at least one of the following: the first terminal acquires the moment of a positioning result; the first terminal acquires the time of a positioning measurement interval; the time when the first terminal starts a positioning measurement process; the network side equipment informs the first terminal of the time of positioning measurement; the time when the network side equipment acquires the positioning result from the first terminal; the first terminal acquires the latest moment of a positioning result; the first terminal acquires the latest moment of a positioning measurement interval; the first terminal starts to position the latest moment of the measurement process; the network side equipment informs the first terminal of the latest moment of positioning measurement; the network side equipment acquires the latest moment of a positioning result from the first terminal; and the first terminal reports the positioning result or the period of the measurement result.

In another possible implementation manner, before the step of sending the uplink scheduling information to the first terminal, the method further includes: sending a designated lead code to the first terminal, wherein the designated lead code is specially used for reporting a positioning measurement result; when the first positioning request is sent based on the specified preamble, or when the network side device sends a second positioning request to a first terminal, the step of sending uplink scheduling information to the first terminal includes: and sending uplink scheduling information containing a logical channel identifier and an RB identifier to the first terminal, wherein the logical channel identifier and the RB identifier have an association relation with the appointed lead code.

In another possible implementation, the designated preamble is transmitted through DCI and/or RRC signaling.

In another possible implementation manner, the first terminal is in an inactive state.

In another possible implementation manner, after the step of sending the uplink scheduling information to the first terminal, the method further includes: under the condition that the positioning data and second uplink data are scheduled simultaneously and the second uplink data and the positioning data are preempted, transmitting the positioning data and informing a second terminal to cancel the transmission of the second uplink data; the second terminal is another terminal except the first terminal, and the second uplink data is another uplink data except the positioning data.

It should be noted that, for the specific implementation process of each implementation manner in this embodiment, reference may be made to the related description in the foregoing method embodiments 200 and/or 300, and for avoiding repetition, no further description is provided herein.

In this embodiment, in the positioning measurement process, the network side device notifies the first terminal of the effective time of the CG, so that the first terminal can send the positioning data based on the scheduling resource configured by the CG. Therefore, on the one hand, compared with the prior art that the pre-configured scheduling resources are for all services on the terminal and the problems of service processing failure and large data transmission delay caused by service type differentiation are avoided, the technical scheme provided by the embodiment can accurately perform corresponding authorization-free configuration on the service type, thereby avoiding the problems of service transmission failure and the like caused by that the first terminal can only perform data transmission according to the pre-configured scheduling resources, reducing data transmission delay and improving wireless communication performance.
