[0029] Figure 1 It is a flowchart of a method for adjusting uplink transmission time provided in an embodiment of the present disclosure.

[0030] Such as Figure 1As shown, the method for adjusting the uplink transmission time is executed by a terminal device, and the method includes the following steps:

[0031] S101, receiving indication information sent by a network device, where the indication information is used to determine the TA adjustment time of the terminal device.

[0034] In some embodiments, the network device may send indication information to the terminal device. Optionally, the terminal device may receive the indication information sent by the network device.

[0035] In some embodiments, the network device may send first indication information to the terminal device through downlink control information. Optionally, the network device may send indication information to the terminal device through Media Access Control Control Element (MAC CE) signaling. That is to say, the indication information may be carried in the MAC CE signaling. Optionally, the terminal device may receive the MAC CE signaling and extract the indication information from the MAC CE signaling.

[0036] In some embodiments, the indication information may directly carry the TA adjustment time.

[0037] In some embodiments, the indication information may carry an adjustment amount for TA adjustment. After obtaining the adjustment amount for TA adjustment, the TA adjustment time determined by the network device for the terminal device may be determined based on the TA adjustment time determination formula.

[0038] In some embodiments, the network device may send the indication information periodically or aperiodically.

[0039] Optionally, the terminal device may send request information to the network device, and based on the request information, the network device may send indication information to the terminal device.

[0040] In some embodiments, the indication information is used to determine the TA adjustment time of the terminal device.

[0041] In some embodiments, the indication information is used to indicate the TA adjustment time of the terminal device.

[0042] In some embodiments, the indication information is used to configure the TA adjustment time of the terminal device.

[0044] S102, determine the TA adjustment time range of the terminal device.

[0045] In the embodiments of the present application, determine the moving speed of the terminal device itself, and determine the time interval between the current indication information and the previous indication information adjacent thereto. According to the moving speed and the time interval, determine the TA adjustment time range.

[0046] In some embodiments, the terminal device may determine its own movement data through a speed sensor.

[0047] In some embodiments, the terminal device may determine its own movement data based on its positioning information within a set time.

[0048] In some embodiments, after receiving the indication information, the time interval between the current indication information and the previous indication information adjacent thereto may be determined. For example, the terminal device may record the reception time (or arrival time) of each indication information, and further, based on the reception times of two adjacent indication information, determine the time interval.

[0049] In some embodiments, the TA adjustment time range of the terminal device may be determined based on the moving speed and the time interval. Optionally, the terminal device may determine the moving distance of the terminal device according to the moving speed and the time interval, and further, determine the TA adjustment time range according to the moving distance and the speed of light.

[0050] S103, adjust the uplink transmission time of the terminal device according to the TA adjustment time range and the TA adjustment time.

[0051] After obtaining the TA adjustment time and the TA adjustment time range, it may be determined whether to adjust the uplink transmission time of the terminal device according to the TA adjustment time range and the TA adjustment time.

[0052] Optionally, in response to the TA adjustment time being within the TA adjustment time range, adjust the current uplink transmission time of the terminal device according to the TA adjustment time; in response to the TA adjustment time not being within the TA adjustment time range, discard the TA adjustment time, that is, do not adjust the uplink transmission time of the terminal device, and the current uplink transmission time of the terminal device can be maintained.

[0053] In the embodiments of the present application, after obtaining the indication information, the uplink transmission time of the terminal device is not directly adjusted based on the TA adjustment time indicated by the indication information, but in combination with the situation of the terminal device itself, a TA adjustment time range suitable for itself is determined. When the TA adjustment time indicated or configured by the network device is within the TA adjustment time range, the uplink transmission time of the terminal device can be adjusted, making the adjustment of the uplink transmission time of the terminal device more accurate and improving the security of the upload transmission. When the TA adjustment time indicated or configured by the network device is not within the TA adjustment time range, the uplink transmission time of the terminal device is not adjusted, which can avoid problems such as call drops, network disconnections, or data link disconnections caused by abnormal TA adjustments, thereby reducing the loss of uplink transmission.

[0054] Figure 2 It is a schematic flowchart of another method for adjusting the uplink transmission time provided by the embodiments of the present disclosure.

[0055] As Figure 2 shown, this method for adjusting the uplink transmission time is executed by the terminal device, and the method includes the following steps:

[0056] S201, send a sounding reference signal (SRS) to the network device, and the SRS is used to determine the adjustment amount for Ta adjustment of the terminal device.

[0057] In some embodiments, the terminal device may send a sounding reference signal (SRS) to the network device based on the reference signal resources configured by the network device, and the quality of the uplink channel can be evaluated based on the SRS. Then, according to the quality evaluation result of the uplink channel, the adjustment amount for the TA adjustment of the terminal device can be accurately determined for the terminal device.

[0058] S202, receive the MAC CE signaling sent by the network device, and the MAC CE signaling includes indication information, and the indication information carries the adjustment amount for TA adjustment.

[0059] S203, determine the TA adjustment time according to the adjustment amount of TA adjustment in the indication information.

[0060] In the embodiments of the present application, the indication information carries an adjustment amount for TA adjustment. After receiving the indication information, the terminal device may determine the TA adjustment time configured by the network device for the terminal device based on the adjustment amount for TA adjustment and in combination with the determination formula of the TA adjustment time.

[0061] For the optional implementation manners of steps S202 to S203, reference may be made to Figure 1 the optional implementation manner of step S101 in Figure 1 and other related parts in the involved embodiments, which will not be elaborated here.

[0062] S204. Determine the moving speed of the terminal device.

[0063] In some embodiments, based on the positioning information of the terminal device, the moving trajectory of the terminal device within a set time may be determined, and then the moving scenario of the terminal device may be determined. The moving scenario may include a high-speed rail moving scenario, a walking scenario, a moving scenario relying on ordinary means of transportation, etc. Further, according to the moving scenario of the terminal device, the moving speed of the terminal device is determined. For example, the moving trajectory may be matched with the trajectory of the high-speed rail line to determine whether it is in the high-speed rail moving scenario. For another example, the moving distance of the terminal device within a unit time may be obtained based on the moving trajectory, and the moving scenario may be determined based on the moving distance.

[0064] In some embodiments, various moving scenarios may be calibrated in advance to obtain the general moving speeds in various moving scenarios. Optionally, a correlation relationship list between the moving scenario and the moving speed is constructed in advance. After determining the current moving scenario of the terminal device, the moving speed associated with the current moving scenario may be determined from the pre-constructed correlation relationship list.

[0065] S205. Determine the time interval between the indication information and the previous adjacent indication information.

[0066] S206. Determine the TA adjustment time range according to the moving speed and the time interval.

[0067] For the optional implementation manners of steps S205 to S206, reference may be made to Figure 1 the optional implementation manner of step S102 in Figure 1 and other related parts in the involved embodiments, which will not be elaborated here.

[0068] S207. In response to the TA adjustment time being within the TA adjustment time range, adjust the uplink transmission time of the terminal device according to the TA adjustment time.

[0069] In some embodiments, in response to the TA adjustment time being within the TA adjustment time range, the current uplink transmission time of the terminal device can be determined, and the current uplink transmission time can be adjusted based on the TA adjustment time. Optionally, the sum of the current uplink transmission time and the TA adjustment time is obtained as the adjusted uplink transmission time of the terminal device. Further, the terminal device performs uplink transmission according to the adjusted uplink transmission time.

[0070] Optionally, the following formula can be used to adjust the uplink transmission time of the terminal device according to the TA adjustment time:

[0071] N TA_new = N TA_old +(T A - 31)·16·64 / 2 u

[0072] where N TA_new represents the adjusted uplink transmission time of the terminal device, and N TA_old represents the current uplink transmission time of the terminal device; T A represents the adjustment amount for TA adjustment indicated by the network device.

[0073] S208, in response to the TA adjustment time not being within the TA adjustment time range, discard the TA adjustment time and maintain the current uplink transmission time of the terminal device.

[0074] In some embodiments, in response to the TA adjustment time not being within the TA adjustment time range, discard the TA adjustment time. In order to enable the terminal device to perform uplink transmission, the current uplink transmission time of the terminal device can be maintained, that is, the terminal device can continue to send uplink transmission according to the current uplink transmission time.

[0075] Exemplarily, the adjustment amount for TA adjustment indicated by the indication information is 45. Further, based on the determination formula of the adjustment time, the TA adjustment time can be obtained as (45 - 31)*0.26 = 3.64 us.

[0076] For example, the terminal device can move at a speed of 99 km / h, and the time interval between two adjacent indication information is 190 ms. Further, the maximum moving distance of the terminal device within the time interval is 5.225 m, that is, 99 km / h * 190 ms = 5.225 m. Further, according to the moving distance and the speed of light, the adjustment time should be 0.035 us, that is, 5.225 / speed of light * 2 = 0.035 us. Based on 0.035 us, the TA adjustment time range of the terminal device can be determined as (0 - 0.035 us).

[0077] Optionally, the TA adjustment time directly indicated by the indication information is 3.64 us. The terminal device can move at a speed of 99 km / h, and the time interval between two adjacent indication information is 190 ms. Further, within the time interval, the maximum moving distance of the terminal device is 5.225 m. According to the moving distance and the speed of light, it is determined that the adjustment time amount should be 0.035 us. Based on 0.035 us, the TA adjustment time amount range of the terminal device can be determined as (0 to 0.035 us).

[0078] The TA adjustment time determined based on the indication information is 3.64 us, which is much larger than 0.035 us. In the embodiments of the present application, the uplink transmission time of the terminal device will not be adjusted based on the TA adjustment time indicated by the network device, and the TA adjustment time indicated by the network device can be discarded to maintain the uplink transmission time of the terminal device.

[0079] In the embodiments of the present application, the scenario where the terminal device is located can be determined by combining the moving speed of the terminal device itself. Different scenarios correspond to different TA adjustment time ranges, making the TA adjustment time range more in line with the actual situation of the terminal device, so as to ensure that the adjustment of the uplink transmission time of the terminal device is more accurate. After obtaining the indication information, the uplink transmission time of the terminal device is not directly adjusted based on the TA adjustment time indicated by the indication information. Instead, the TA adjustment time range suitable for itself is determined by combining the situation of the terminal device itself. When the TA adjustment time indicated or configured by the network device is within the TA adjustment time range, the uplink transmission time of the terminal device can be adjusted, making the adjustment of the uplink transmission time of the terminal device more accurate and improving the security of the upload transmission. When the TA adjustment time indicated or configured by the network device is not within the TA adjustment time range, the uplink transmission time of the terminal device is not adjusted, which can avoid problems such as call drop, network disconnection, or data link disconnection caused by abnormal TA adjustment, thereby reducing the loss of uplink transmission.

[0080] Figure 3 It is an interaction schematic diagram of a method for adjusting uplink transmission time provided by an embodiment of the present disclosure.

[0081] As Figure 3 shown, the method for adjusting uplink transmission time includes the following steps:

[0082] S301, the terminal device sends SRS to the base station.

[0083] S302, the base station determines the adjustment amount for TA adjustment based on SRS.

[0084] S303, the base station sends MACCE to the terminal device.

[0085] Among them, MACCE includes indication information, and the indication information carries an adjustment amount for TA adjustment.

[0086] S304. The terminal device determines the TA adjustment time based on the adjustment amount of the TA adjustment.

[0087] S305. The terminal device determines the TA adjustment time range.

[0088] In some embodiments, steps S304 and S305 can be executed simultaneously or the execution order can be exchanged, and this application does not limit this. S3061. In response to the TA adjustment time being within the TA adjustment time range, the uplink transmission time of the terminal device is adjusted according to the TA adjustment time.

[0089] S3062. In response to the TA adjustment time not being within the TA adjustment time range, the TA adjustment time is discarded, and the current uplink transmission time of the terminal device is maintained.

[0090] It can be understood that steps S3061 and S3062 are executed alternatively.

[0091] In the embodiments of this application, the scenario where the terminal device is located can be determined in combination with the moving speed of the terminal device itself. Different scenarios correspond to different TA adjustment time ranges, making the TA adjustment time range more in line with the actual situation of the terminal device, so as to ensure that the adjustment of the uplink transmission time of the terminal device is more accurate. After obtaining the indication information, the uplink transmission time of the terminal device is not directly adjusted based on the TA adjustment time indicated by the indication information, but the TA adjustment time range suitable for itself is determined in combination with the situation of the terminal device itself. When the TA adjustment time indicated or configured by the network device is within the TA adjustment time range, the uplink transmission time of the terminal device can be adjusted, making the adjustment of the uplink transmission time of the terminal device more accurate and improving the security of the upload transmission. When the TA adjustment time indicated or configured by the network device is not within the TA adjustment time range, the uplink transmission time of the terminal device is not adjusted, which can avoid problems such as call drop, network disconnection or data link disconnection caused by abnormal TA adjustment, thereby reducing the loss of uplink transmission.

[0094] In some embodiments, terms such as "component carrier", "cell", "frequency carrier", "carrier frequency" can be used interchangeably.

[0124] In the embodiments of the present application, the scenario where the terminal device is located can be determined in combination with the moving speed of the terminal device itself. Different scenarios correspond to different TA adjustment time ranges, making the TA adjustment time range more in line with the actual situation of the terminal device, so as to ensure more accurate adjustment of the uplink transmission time of the terminal device. After obtaining the indication information, the uplink transmission time of the terminal device is not directly adjusted based on the TA adjustment time indicated by the indication information.
