Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method, apparatus, device, and storage medium for triggering TAR. Background Technology

[0002] In a communication system, after receiving a handover command, the terminal device executes a handover process. During the downlink synchronization step with the target cell, the terminal device instructs the Media Access Control (MAC) layer to trigger a Timing Advance Reporting (TAR) to subsequently report the TAR to the network device. However, the terminal device also performs a MAC reset during the handover process. Since the triggered TAR is canceled when the UE performs a MAC reset, the TAR may fail to be transmitted successfully. Summary of the Invention

[0003] The present disclosure provides a method, apparatus, device, and storage medium for triggering TARs, in order to solve the technical problem that related technologies often accidentally cancel the triggered TARs, resulting in the failure of TARs to be successfully transmitted.

[0004] In a first aspect, embodiments of this disclosure provide a method for triggering a TAR (Temporary Asynchronous Response), which is executed by a terminal device, including:

[0005] Upon receiving a connection reconfiguration message indicating a handover command, the handover process is executed.

[0006] At a specific moment during the handover process, the media access control (MAC) layer of the terminal device is instructed to trigger TAR.

[0007] This disclosure provides a method for triggering a TAR (Connection Reconfiguration Message). In response to receiving a connection reconfiguration message indicating a handover command, a terminal device performs a handover process. The terminal device instructs the MAC layer to trigger the TAR at a specific moment during the handover process. This specific moment can be at least one of the following: after a MAC reset is completed, after MAC layer configuration is completed, after connection reconfiguration is completed, or after a connection reconfiguration completion message is generated. Therefore, by triggering the TAR after a MAC reset or after MAC layer configuration, this method avoids the situation where a triggered TAR is mistakenly canceled due to a MAC reset, ensuring successful TAR reporting. Furthermore, by triggering the TAR after connection reconfiguration is completed or after a connection reconfiguration completion message is generated, the reconfiguration completion message is generated and sent promptly, preventing the network device from mistakenly believing the reconfiguration has failed and rescheduling resources for the terminal device due to the connection reconfiguration completion message not being sent in time, thus preventing unnecessary waste of resources.

[0023] The terminal device is in the moment before the wireless resource control connection reconfiguration is completed;

[0024] The terminal device at the moment after the wireless resource control connection reconfiguration is completed;

[0025] The moment before the terminal device submits the Radio Resource Control Connection Reconfiguration Complete message to the lower layer of the terminal device;

[0026] The time after the terminal device submits the Radio Resource Control Connection Reconfiguration Complete message to the lower layer of the terminal device.

[0027] Optionally, instructing the MAC layer of the terminal device to trigger TAR includes:

[0080] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0081] To facilitate understanding, the terminology used in this application will be introduced first.

[0082] 1. Timing Advance (TA) value

[0083] Used for uplink transmission on terminal devices, it refers to the terminal device sending data packets in advance according to the corresponding instructions.

[0084] 2. Timely advance reporting (TAR)

[0085] The terminal device needs to report the TAR to the network device so that the network device knows the UE-gNB Round Trip Time (RTT) so that the network device can determine the uplink scheduling timing or UL ACK / NACK feedback timing based on the RTT.

[0086] To better understand the method for determining sidelink duration disclosed in the embodiments of this application, the communication system to which the embodiments of this application are applicable is first described below.

[0087] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. The communication system may include, but is not limited to, a network device and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, two or more network devices and two or more terminal devices may be included. Figure 1 The communication system shown is an example including a network device 11 and a terminal device 12.

[0088] It should be noted that the technical solutions of this disclosure can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, 5th Generation (5G) mobile communication systems, 5G New Radio (NR) systems, or other future new mobile communication systems.

[0089] The network device 11 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 11 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This disclosure does not limit the specific technology or device form used in the network device. The network device provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0090] The terminal device 12 in this disclosure is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of this disclosure do not limit the specific technology or device form used in the terminal device.

[0091] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0092] The triggering method, apparatus, device, and storage medium of TAR provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0093] Figure 2 This is a flowchart illustrating a TAR triggering method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 2 As shown, the triggering method for this TAR may include the following steps:

[0094] Step 201: In response to receiving a connection reconfiguration message indicating a handover command, perform the handover process.

[0095] For a detailed description of the connection reconfiguration message and handover process, please refer to the existing technical description.

[0096] Step 202: At a specific moment during the handover process, instruct the MAC layer of the terminal device to trigger TAR.

[0097] In one embodiment of this disclosure, the specific moment can be at least one of the following:

[0098] The moment immediately after a MAC reset is executed;

[0099] The moment after the MAC layer configuration is completed;

[0100] The moment after connection reconfiguration is completed;

[0101] The moment after the connection reconfiguration completion message is generated.

[0102] As can be seen from the above, in one embodiment of this disclosure, the terminal device's MAC layer is instructed to trigger TAR after MAC reset is executed or after MAC layer configuration is executed. That is, TAR will not be triggered before MAC reset is executed or before MAC layer configuration is executed, thereby avoiding the situation where "the triggered TAR is mistakenly canceled due to the execution of MAC reset" and ensuring that TAR can be successfully reported.

[0103] Furthermore, in another embodiment of this disclosure, the MAC layer of the terminal device is instructed to trigger TAR after the connection reconfiguration is completed or after the connection reconfiguration completion message is generated. That is, TAR is not triggered before the connection reconfiguration is performed or before the connection reconfiguration completion message is generated. This reduces the process required before the connection reconfiguration is performed or before the connection reconfiguration completion message is generated, so that the reconfiguration completion message can be generated and sent in a timely manner. This avoids the situation where "the network device mistakenly believes that the reconfiguration has failed and reschedules resources for the terminal device because the connection reconfiguration completion message is not sent in a timely manner," thus preventing unnecessary waste of resources.

[0104] Furthermore, in one embodiment of this disclosure, the method for instructing the MAC layer of the terminal device to trigger TAR can specifically be: the terminal device instructs its MAC layer to trigger TAR through its Radio Resource Control (RRC) layer.

[0105] In summary, the TAR triggering method provided in this disclosure, in response to receiving a connection reconfiguration message indicating a handover command, the terminal device executes a handover process. The terminal device instructs the MAC layer to trigger the TAR at a specific moment during the handover process. This specific moment can be at least one of the following: after MAC reset is completed, after MAC layer configuration is completed, after connection reconfiguration is completed, or after a connection reconfiguration completion message is generated. Therefore, by triggering the TAR after MAC reset or after MAC layer configuration, this method avoids the situation where the triggered TAR is mistakenly canceled due to MAC reset, ensuring successful TAR reporting. Furthermore, by triggering the TAR after connection reconfiguration is completed or after a connection reconfiguration completion message is generated, the reconfiguration completion message is generated and sent promptly, preventing the network device from mistakenly believing the reconfiguration has failed and rescheduling resources for the terminal device due to the connection reconfiguration completion message not being sent in time, thus preventing unnecessary waste of resources.

[0106] Figure 3 This is a flowchart illustrating a TAR triggering method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 3 As shown, the triggering method for this TAR may include the following steps:

[0107] Step 301: In response to receiving a connection reconfiguration message indicating a handover command, execute the handover process.

[0108] Step 302: After performing MAC reset, instruct the MAC layer of the terminal device to trigger TAR.

[0109] For a detailed description of steps 301-302, please refer to the above embodiment description.

[0110] In summary, the TAR triggering method provided in this disclosure triggers the TAR after a MAC reset, which avoids the situation where "the triggered TAR is mistakenly canceled due to the execution of a MAC reset" and ensures that the TAR can be successfully reported.

[0111] Figure 4 This is a flowchart illustrating a TAR triggering method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 4 As shown, the triggering method for this TAR may include the following steps:

[0112] Step 401: In response to receiving a connection reconfiguration message indicating a handover command, perform the handover process.

[0113] Step 402: After completing the MAC layer configuration, instruct the MAC layer of the terminal device to trigger TAR.

[0114] For a detailed description of steps 401-402, please refer to the above embodiment description.

[0115] In summary, the TAR triggering method provided in this disclosure triggers the TAR after the MAC layer configuration is completed, which avoids the situation where "the triggered TAR is accidentally canceled due to the execution of MAC reset" and ensures that the TAR can be successfully reported.

[0116] Figure 5 This is a flowchart illustrating a TAR triggering method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 5 As shown, the triggering method for this TAR may include the following steps:

[0117] Step 501: In response to receiving a connection reconfiguration message indicating a handover command, perform the handover process.

[0118] Step 502: After completing the connection reconfiguration, instruct the MAC layer of the terminal device to trigger TAR.

[0119] For a detailed description of steps 501-502, please refer to the above embodiment.

[0120] In summary, the TAR triggering method provided in this disclosure triggers TAR after the connection reconfiguration is completed, which can generate and send a reconfiguration completion message in a timely manner, avoiding the situation where "the network device mistakenly believes that the reconfiguration has failed and reschedules resources for the terminal device because the connection reconfiguration completion message is not sent in a timely manner," thus preventing unnecessary waste of resources.

[0123] Step 602: After generating the connection reconfiguration complete message, instruct the MAC layer of the terminal device to trigger TAR.

[0124] For a detailed description of steps 601-602, please refer to the above embodiment description.

[0125] In summary, the TAR triggering method provided in this disclosure triggers TAR after generating the connection reconfiguration completion message, which can generate and send the reconfiguration completion message in a timely manner, avoiding the situation where "the network device mistakenly believes that the reconfiguration has failed and reschedules resources for the terminal device because the connection reconfiguration completion message is not sent in a timely manner," thus preventing unnecessary waste of resources.

[0126] Figure 7 This is a flowchart illustrating a TAR triggering method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 7 As shown, the triggering method for this TAR may include the following steps:

[0127] Step 701: In response to receiving a connection reconfiguration message indicating a handover command, perform the handover process.

[0128] Step 702: In response to the connection reconfiguration message containing Reconfiguration With Sync and the TAR being configured (TA-Report is configured), after the MAC reset is completed during the Reconfiguration withsync process, the MAC layer of the terminal device is instructed to trigger TAR.

[0129] In one embodiment of this disclosure, the connection reconfiguration message may be an RRCReconfiguration (Radio Resource Control Reconfiguration) message.

[0130] Furthermore, for a detailed description of steps 701-702, please refer to the above embodiments.

[0131] In summary, the TAR triggering method provided in this disclosure triggers the TAR after a MAC reset, which avoids the situation where "the triggered TAR is mistakenly canceled due to the execution of a MAC reset" and ensures that the TAR can be successfully reported.

[0133] Step 801: In response to receiving a connection reconfiguration message indicating a handover command, perform the handover process.

[0134] Step 802: In response to the connection reconfiguration message containing Reconfiguration With Sync and TAR being configured, during the execution of the Reconfiguration with sync process, after the low-level configuration of the terminal device is completed according to spCellConfigCommon (special cell general configuration), the MAC layer of the terminal device is instructed to trigger TAR.

[0135] The underlying layer of the terminal device can be the MAC layer.

[0136] For a detailed description of steps 801-802, please refer to the above embodiment description.

[0137] In summary, the TAR triggering method provided in this disclosure triggers the TAR after the MAC layer configuration is completed, which avoids the situation where "the triggered TAR is accidentally canceled due to the execution of MAC reset" and ensures that the TAR can be successfully reported.
