Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and device for delay status reporting. Background Art

[0002] With the continuous development of wireless communication systems, data transmission delays are constantly decreasing, and transmission capacity is increasing. Wireless communication systems are gradually infiltrating some services that require strong real-time performance and large data capacity, such as video transmission, cloud gaming (CG), and extended reality (XR). Among them, XR refers to a combination of real and virtual environments that can interact with humans and machines through computer technology and wearable devices. It is a general term for various forms such as augmented reality (AR), virtual reality (VR), and mixed reality (MR).

[0003] Services such as XR have short latency requirements. For example, for XR services, the latency for one-way data transmission between access network equipment and terminals should be 5-10 milliseconds (ms). To meet latency requirements, the new radio (NR) communication system introduces a delay status report (DSR). The terminal can send a DSR to the access network device, which is used to report information related to data latency. The access network device can schedule resources for the terminal based on the DSR. How to trigger the reporting of the DSR requires further study. Summary of the invention

[0004] The present application provides a communication method and device for triggering DSR reporting.

[0005] In a first aspect, an embodiment of the present application provides a communication method, which can be applied to a first device, and the first device can be a terminal or a module in the terminal (such as a circuit, a chip, a chip system or a processor), and can also be a logical node, a logical module or software that can implement all or part of the terminal functions. Among them, the method may include: triggering the reporting of DSR when a first condition is met, and the DSR can be used to report information related to data delay, and the first condition may at least include: there is data in the logical channel group (logic channel group, LCG) with a remaining scheduling delay less than the delay threshold, and the first timer is not running; start the first timer.

[0006] By using this method, when the reporting of DSR is triggered, the first device can run the first timer. During the operation of the first timer, the reporting of DSR will not be triggered, thereby avoiding repeated reporting of DSR, and further avoiding the waste of uplink resources caused by repeated reporting of DSR, saving uplink resources, and reducing signaling overhead.

[0007] In one possible design, the method further includes: receiving timer configuration information, where the timer configuration information can be used to configure the duration of the first timer. With this design, the first device can quickly and accurately determine the duration of the first timer based on the timer configuration information.

[0008] In one possible design, the method further includes: sending timer indication information, where the timer indication information can be used to indicate the duration of the first timer. With this design, the first device can send timer indication information for indicating the duration of the first timer, so that the second device can know the duration of the first timer and manage the first device accordingly.

[0011] In one possible design, the method further includes: the duration of the first timer is related to the minimum remaining scheduling delay of data in the LCG. Through this design, the first device can determine the appropriate duration of the first timer according to the minimum remaining scheduling delay in the LCG, thereby effectively avoiding repeated reporting of DSR, avoiding waste of uplink resources caused by repeated reporting of DSR, saving uplink resources, and reducing signaling overhead.

[0012] In a possible design, starting the first timer may include: starting the first timer when triggering the reporting of the DSR; or starting the first timer when generating information including the DSR; or starting the first timer when reporting the information including the DSR. With this design, the first device can flexibly start the first timer.

[0013] In one possible design, the method further includes: receiving threshold configuration information, where the threshold configuration information can be used to configure the delay threshold.

[0076] The technical solution in the embodiment of the present application will be described below in conjunction with the accompanying drawings in the embodiment of the present application. The technical solution in the embodiment of the present application can be applied to various communication systems, such as universal mobile telecommunications system (UMTS), wireless local area network (WLAN), wireless fidelity (Wi-Fi) system, fourth generation (4G) mobile communication system (such as long term evolution (LTE) system), fifth generation (5G) mobile communication system (such as NR system), and future evolved communication system (such as sixth generation (6G) mobile communication system).

[0077] The present application will present various aspects, embodiments or features around a system that may include multiple devices, components, modules, etc. It should be understood and appreciated that each system may include additional devices, components, modules, etc., and / or may not include all of the devices, components, modules, etc. discussed in conjunction with the figures. In addition, combinations of these schemes may also be used.

[0078] To facilitate understanding of the embodiments of the present application, Figure 1 A possible, non-limiting system schematic is shown. Figure 1As shown, the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 10 may further include the Internet 300.

[0079] RAN 100 includes at least one RAN node (e.g. Figure 1 110a and 110b, collectively referred to as 110) and at least one terminal (such as Figure 1 RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 1 The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 may be different physical devices, or may be the same physical device that integrates the core network logical function and the radio access network logical function.

[0080] RAN 100 may be a cellular system related to the third generation partnership project (3GPP), for example, a 4G, 5G mobile communication system, or a future evolution system (for example, a 6G mobile communication system). RAN 100 may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (cloud radio access network, CRAN), or a WiFi system. RAN 100 may also be a communication system that integrates two or more of the above systems.

[0081] The RAN node 110, which may also be sometimes referred to as a RAN entity or an access node, constitutes a part of the communication system to help the terminal achieve wireless access. The multiple RAN nodes 110 in the communication system 10 may be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative, for example, Figure 1 The network element 120i may be a helicopter or a drone, which may be configured as a mobile base station. For the terminals 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The RAN node 110 and the terminal 120 are sometimes referred to as communication devices, for example Figure 1The network elements 110a and 110b may be understood as communication devices having base station functions, and the network elements 120a-120j may be understood as communication devices having terminal functions.

[0082] The RAN node may also be expressed in different ways, such as access network equipment. Unless otherwise specified in this application, the access network equipment is used for expression.

[0083] In one possible scenario, the access network device may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. The access network device may be a macro base station (e.g. Figure 1 110a in), micro base stations or indoor stations (such as Figure 1 110b in the example), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the access network device may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the access network device in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The access network device in the present application may also be a logical node, a logical module or software that can implement all or part of the functions of the access network device.

[0084] In another possible scenario, multiple access network devices collaborate to assist the terminal in achieving wireless access, and different access network devices respectively implement part of the functions of the base station. For example, the access network device can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

[0085] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called an open CU (open CU, O-CU), DU may also be called an open DU (open DU, O-DU), CU-CP may also be called an open CU-CP (open CU-CP, O-CU-CP), CU-UP may also be called an open CU-UP (open CU-UP, O-CU-UP), and RU may also be called an open RU (open RU, O-RU). Any unit in the CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0086] The terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely used in various scenarios, for example, device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, etc. The embodiments of the present application do not limit the device form of the terminal.

"Receiving information from a device (such as a terminal)" or "receiving information from a device (such as a terminal)" can be understood as the source of the information being the device, and can include directly or indirectly receiving information from the device. The information may be processed as necessary between the source and destination of the information, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be repeated here.

[0088] The communication system and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person of ordinary skill in the art can appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0089] The following first explains the relevant terms involved in the embodiments of the present application. It should be noted that these explanations are intended to make the embodiments of the present application easier to understand and should not be regarded as limiting the scope of protection claimed by the present application.

[0090] (1)DSR, which can be used to report information related to data delay.

[0091] In some possible ways, the DSR may be used to report the remaining scheduling delay of data in the LCG. Exemplarily, the DSR may be used to report the minimum remaining scheduling delay of data in the LCG. For example, if the remaining scheduling delay of data 1 in the LCG is 5 milliseconds (ms) and the remaining scheduling delay of data 2 in the LCG is 8 ms, then the DSR may be used to report the remaining scheduling delay of data 1 in the LCG, for example, the DSR includes 5 ms.

[0092] In some other possible ways, DSR can be used to report the remaining amount of the third data in the LCG, and the remaining scheduling delay of the third data is less than the delay threshold. The specific content of the delay threshold will be described in Figure 3 The method is described in detail in the following section and will not be expanded here.

[0093] In some examples, if the remaining scheduling delay of data 1 in LCG is 5 ms, the remaining scheduling delay of data 2 in LCG is 8 ms, and the delay threshold is 7 ms, the third data is data 1, and DSR can be used to report the remaining data volume of data 1. For example, the total data volume of data 1 is 50 megabytes (MB). If the remaining data volume of data 1 is 30 MB when generating information including DSR, then DSR can include 30 MB.

[0094] In other examples, if the remaining scheduling delay of data 1 in LCG is 5ms, the remaining scheduling delay of data 2 in LCG is 8ms, the remaining scheduling delay of data 3 in LCG is 6ms, and the delay threshold is 7ms, then the third data includes data 1 and data 3, and DSR can be used to report the remaining data volume of data 1 and data 3. For example, the total data volume of data 1 is 50MB, and the total data volume of data 3 is 30MB. If the remaining data volume of data 1 is 30MB and the remaining data volume of data 3 is 30MB when generating information including DSR, then DSR may include 60MB.

[0095] (2)LCG:

[0096] LCG may include multiple logical channels (logic channels, LCHs). The parameters of LCHs may be configured by the access network device. Exemplarily, the configuration information of LCHs includes parameters such as the index and priority of LCGs. When configuring the parameters of LCHs, the access network device may configure LCHs with the same or similar priorities in one LCG.

[0097] The priority of LCH is related to the quality of service (QoS) of the data transmitted by the LCH. For example, the QoS of the data can be marked by the core network using a QoS flow identifier (QFI). One form of QFI is a 5G QoS identifier (5G QoS identifier, 5QI). A 5QI value may correspond to at least one of the following QoS parameters: priority, packet delay budget (PDB), packet error rate, or default averaging window. The priority of LCH is the same as the priority in the 5QI corresponding to the data transmitted by the LCH.

[0098] (3) Remaining scheduling delay: refers to how long it takes for data to be transmitted. For example, data 1 arrives at the terminal cache at 0 ms, and the PDB of data 1 is 10 ms, which means that data 1 needs to be transmitted within 10 ms. If the current time is 3 ms, the remaining scheduling delay of data 1 is 7 ms.

[0099] It should be understood that the remaining scheduling delay may also have other names, such as remaining scheduling time, remaining packet delay budget or remaining transmission time, etc., as long as they represent the same meaning.

[0100] The reporting of DSR is generally triggered based on the delay threshold. For example, one LCG corresponds to one delay threshold. When there is data in the LCG with a remaining scheduling delay less than or equal to the delay threshold, the terminal can trigger the reporting of DSR. For example, the PDB of data 1 in the LCG is 10ms and the delay threshold is 7ms. Figure 2As shown, data 1 arrives at the terminal's cache at 0ms. Between 0 and 3ms, the remaining scheduling delay of data 1 is greater than the delay threshold, and the terminal does not trigger DSR reporting. At 3ms, the remaining scheduling delay of data 1 is equal to the delay threshold, and the terminal triggers DSR reporting. At 4ms, the terminal can send a media access control (MAC) control element (MAC CE) containing DSR to the access network device through the physical uplink shared channel (PUSCH). Between 4 and 7ms, the remaining scheduling delay of data 1 is less than the delay threshold, and the terminal triggers DSR reporting. At 7ms, the terminal sends a MAC CE containing DSR to the access network device through PUSCH. Between 7 and 9ms, the remaining scheduling delay of data 1 is less than the delay threshold, and the terminal triggers DSR reporting. At 9ms, the terminal sends a MAC CE containing DSR to the access network device through PUSCH.

[0101] It can be seen that when the remaining scheduling delay of data 1 is less than the delay threshold, the terminal will use each available PUSCH to send a MAC CE containing DSR to the access network device, that is, the terminal may send DSR multiple times. The access network device only needs to receive one DSR to obtain the delay information of the terminal data. Therefore, triggering the reporting of DSR by the above method will result in repeated sending of DSR, resulting in a waste of resources.

[0102] In view of this, an embodiment of the present application provides a communication method. Figure 3 A flow chart corresponding to the communication method provided in the embodiment of the present application. Figure 3 The method is illustrated by taking the first device and the second device as the execution subjects of the interaction as an example, but the present application does not limit the execution subjects of the interaction. For example, the first device can be a terminal, or a module applied to the terminal, such as a circuit, a chip, a chip system or a processor, or a logical node, a logical module or software that can realize all or part of the terminal functions; the second device can also be an access network device, or a module applied to the access network device, such as a circuit, a chip, a chip system or a processor, or a logical node, a logical module or software that can realize all or part of the access network device functions. Figure 3 As shown, the method includes:

[0103] S301: When a first condition is met, the first device triggers DSR reporting.

[0104] The first condition at least includes the following condition 1 and condition 2. It should be understood that the first condition may include only condition 1 and condition 2, or may include other conditions in addition to condition 1 and condition 2. Condition 1 and condition 2 are described in detail below.

[0105] Condition 1: There is data in the LCG whose remaining scheduling delay is less than the delay threshold. For example, the delay threshold is 7ms. If the remaining scheduling delay of data 1 in the LCG is 5ms, there is data in the LCG whose remaining scheduling delay is less than the delay threshold, and the first device can determine that condition 1 is met. If the remaining scheduling delay of the data in the LCG is greater than or equal to 7ms, the first device can determine that condition 1 is not met.

[0106] In some implementations, condition 1 may be replaced by: condition 3: data exists in the LCG indicating that the remaining scheduling delay is less than or equal to the delay threshold. That is, the first condition includes at least: condition 3 and condition 2. The specific content of condition 3 can refer to the description of condition 1, except that less than is replaced by less than or equal to, and greater than or equal to is replaced by greater than, which will not be repeated here.

[0107] Optionally, before determining whether condition 1 or condition 3 is met, the first device may determine a delay threshold. The specific content of the determination will be described in the following methods b1 to b4 and will not be expanded here.

[0108] In some other implementations, condition 1 may be replaced by: Condition 4: There is data in the LCG whose remaining scheduling delay belongs to the first delay range. That is, the first condition includes at least: Condition 4 and Condition 2. For example, the first delay range is 2 to 7 ms. If the remaining scheduling delay of data 1 in the LCG is 5 ms, then there is data in the LCG whose remaining scheduling delay belongs to the first delay range, and the first device may determine that condition 4 is satisfied. If the remaining scheduling delay of the data in the LCG is not within 2 to 7 ms, the first device may determine that condition 4 is not satisfied. Among them, the first delay range may be pre-set, for example, specified by the protocol, or included in the factory settings of the first device, or included in the subscriber identity module (SIM) card of the first device; or, the first delay range may also be determined by the first device; or, the first delay range may also be obtained by the first device from other devices (for example, the second device).

[0109] Condition 2: The first timer is not running. In some examples, the first timer is not running when the first timer is not started, that is, the first timer is in a non-running state. In other examples, the first timer is not running when the first timer times out and there is no additional input for determining the state of the first timer.

[0110] In some possible ways, the first timer is associated with the LCG, and one LCG may be associated with one first timer. For example, LCG 1 is associated with first timer 1. When there is data in LCG 1 with a remaining scheduling delay less than a delay threshold, and the first timer 1 is not running, the first device may trigger the reporting of the DSR.

[0111] In some other possible methods, the first timer is associated with the LCH in the LCG, and one LCH can be associated with one first timer.

[0112] In some examples, when the first condition includes condition 1 and condition 2, the first timer in condition 2 is associated with the first LCH in the LCG, and the first LCH is used to transmit data in condition 1 whose remaining scheduling delay is less than the delay threshold; in other words, the first condition at least includes: data whose remaining scheduling delay is less than the delay threshold exists in the first LCH in the LCG, and the first timer associated with the first LCH is not started. For example, LCG 1 includes LCH 1 and LCH 2, LCH 1 is associated with the first timer 2, and LCH 2 is associated with the first timer 3. When data whose remaining scheduling delay is less than the delay threshold exists in LCH 1, and the first timer 2 is not running, the first device can trigger the reporting of the DSR.

[0113] In some other examples, when the first condition includes condition 3 and condition 2, the first timer in condition 2 is associated with the first LCH in the LCG, and the first LCH is used to transmit data in condition 3 whose remaining scheduling delay is less than or equal to the delay threshold; in other words, the first condition at least includes: data whose remaining scheduling delay is less than or equal to the delay threshold exists in the first LCH in the LCG, and the first timer associated with the first LCH is not started. For example, LCG 1 includes LCH 1 and LCH 2, LCH 1 is associated with the first timer 2, and LCH 2 is associated with the first timer 3. When data whose remaining scheduling delay is less than or equal to the delay threshold exists in LCH 1, and the first timer 2 is not running, the first device can trigger the reporting of the DSR.

[0114] In some other examples, when the first condition includes condition 4 and condition 2, the first timer in condition 2 is associated with the first LCH in the LCG, and the first LCH is used to transmit data whose remaining scheduling delay in condition 4 belongs to the first delay range; in other words, the first condition at least includes: data whose remaining scheduling delay belongs to the first delay range exists in the first LCH in the LCG, and the first timer associated with the first LCH is not started. For example, LCG 1 includes LCH 1 and LCH 2, LCH 1 is associated with the first timer 2, and LCH 2 is associated with the first timer 3. When data whose remaining scheduling delay belongs to the first delay range exists in LCH 1, and the first timer 2 is not running, the first device can trigger the reporting of the DSR.

[0115] In this application, DSR can be used to report information related to data delay. The specific content of DSR can be referred to the explanation part of the relevant terms above, which will not be repeated here.

[0116] S302: The first device starts a first timer.

[0117] There may be multiple timings for the first device to start the first timer, for example, timing a1, timing a2 or timing a3.

[0118] Timing a1: When triggering the reporting of DSR, the first device may start the first timer. Figure 4 As shown, the PDB of data 1 in LCG is 10ms, and the delay threshold is 7ms. Data 1 in LCG arrives at the cache of the terminal at 0ms. At 3ms, the remaining scheduling delay of data 1 is less than or equal to the delay threshold, and the first timer is not started. The first device can trigger the reporting of DSR and start the first timer when the reporting of DSR is triggered.

[0119] Timing a2: When generating information including DSR (eg, MAC CE including DSR), the first device may start the first timer. Figure 4 As shown, the PDB of data 1 in LCG is 10ms, and the delay threshold is 7ms. Data 1 in LCG arrives at the cache of the terminal at 0ms. At 3ms, the remaining scheduling delay of data 1 is less than or equal to the delay threshold, and the first timer is not started, and the first device can trigger the reporting of DSR. If the first device has available uplink resources (such as PUSCH) at 4ms, the first device can generate a MAC CE containing DSR between 3 and 4ms, and start the first timer when generating the MAC CE containing DSR.

[0120] Opportunity a3: When reporting information including DSR (eg, MAC CE including DSR), the first device may start the first timer. Figure 4 As shown, the PDB of data 1 in LCG is 10ms, and the delay threshold is 7ms. Data 1 in LCG arrives at the cache of the terminal at 0ms. At 3ms, the remaining scheduling delay of data 1 is less than or equal to the delay threshold, and the first timer is not started, and the first device can trigger the reporting of DSR. If the first device has available uplink resources (such as PUSCH) at 4ms, the first device can report a MAC CE containing DSR at 4ms, and start the first timer when reporting the MAC CE containing DSR.

[0121] Optionally, after the first device starts the first timer, the first timer may work in a variety of ways, which are illustrated below. In some examples, after the first device starts the first timer, the first timer may start timing from 0ms, and the timing time of the first timer gradually increases. When the timing time of the first timer increases to the duration of the first timer, the first timer times out. In other examples, after the first device starts the first timer, the first timer starts timing from the duration of the first timer, and the timing time of the first timer gradually decreases. When the timing time of the first timer is reduced to 0ms, the first timer times out. When using the first timer, the first device needs to determine the duration of the first timer, and the content of the determination will be described in the following methods a1 to a6, which will not be expanded here.

[0122] In some possible ways, the first timer is associated with the LCG. In S302, the first device may start the first timer associated with the LCG.

[0123] In some other possible approaches, the first timer is associated with the LCH within the LCG.

[0124] In some examples, when the first condition at least includes: there is data in the first LCH in the LCG with a remaining scheduling delay less than the delay threshold, and the first timer associated with the first LCH is not started, in S302, the first device may start the first timer associated with the first LCH. For example, LCG 1 includes LCH 1 and LCH 2, LCH 1 is associated with the first timer 2, and LCH2 is associated with the first timer 3. When there is data in LCH 1 with a remaining scheduling delay less than the delay threshold, and the first timer 2 is not running, the first device may trigger the reporting of the DSR and start the first timer 2.

[0125] In some other examples, when the first condition at least includes: data that the remaining scheduling delay is less than or equal to the delay threshold exists in the first LCH in the LCG, and the first timer associated with the first LCH is not started, in S302, the first device may start the first timer associated with the first LCH. For example, LCG 1 includes LCH 1 and LCH 2, LCH 1 is associated with the first timer 2, and LCH 2 is associated with the first timer 3. When data that the remaining scheduling delay is less than or equal to the delay threshold exists in LCH 1, and the first timer 2 is not running, the first device may trigger the reporting of the DSR and start the first timer 2.

[0126] In some other examples, when the first condition at least includes: there is data in the first LCH in the LCG whose remaining scheduling delay belongs to the first delay range, and the first timer associated with the first LCH is not started, in S302, the first device may start the first timer associated with the first LCH. For example, LCG 1 includes LCH 1 and LCH 2, LCH 1 is associated with the first timer 2, and LCH 2 is associated with the first timer 3. When there is data in LCH 1 whose remaining scheduling delay belongs to the first delay range, and the first timer 2 is not running, the first device may trigger the reporting of the DSR and start the first timer 2.

[0127] pass Figure 3 In the method shown, when the reporting of DSR is triggered, the first device can run the first timer. During the operation of the first timer, the reporting of DSR will not be triggered, thereby avoiding repeated reporting of DSR, thereby avoiding the waste of uplink resources caused by repeated reporting of DSR, saving uplink resources, and reducing signaling overhead.

[0128] As mentioned above, the first device may determine the duration of the first timer in various ways, such as way a1, way a2, way a3, way a4, way a5 or way a6.

[0129] Method a1:

[0130] The second device sends timer configuration information; correspondingly, the first device receives the timer configuration information. The timer configuration information is used to configure the duration of the first timer. In this way, the first device can determine the duration of the first timer according to the timer configuration information. Exemplarily, the timer configuration information includes the duration of the first timer. For example, the timer configuration information includes 5ms, indicating that the duration of the first timer is 5ms. According to the timer configuration information, the first device can determine that the duration of the first timer is 5ms.

[0131] The second device may actively send the timer configuration information to the first device, or may send the timer configuration information to the first device based on the request of the first device, and this application does not limit this. The timer configuration information may be carried in a traditional message or in a new message, and this application does not limit this. Exemplarily, the timer configuration information may be carried in a radio resource control (RRC) message.

[0132] Through manner a1, the first device can quickly and accurately determine the duration of the first timer according to the timer configuration information.

[0133] Method a2:

[0134] The first device sends timer indication information; correspondingly, the second device receives the timer indication information. The timer indication information is used to indicate the duration of the first timer. That is, in method a2, the first device can determine the duration of the first timer by itself, and report the determined duration of the first timer to the second device. Exemplarily, the timer indication information includes the duration of the first timer. For example, the timer indication information includes 5ms, indicating that the duration of the first timer is 5ms.

[0135] The first device may actively send the timer indication information to the second device, or may send the timer indication information to the second device based on the request or instruction of the second device, and this application does not limit this. The timer indication information may be carried in a traditional message or in a new message, and this application does not limit this. Exemplarily, the timer indication information may be carried in uplink assistant information (UAI), MAC CE or uplink control information (UCI).

[0136] Through mode a2, the first device can determine the duration of the first timer by itself, so as to quickly and accurately obtain the duration of the first timer. In addition, the first device can send timer indication information indicating the duration of the first timer to the second device, so that the second device can manage the first device accordingly.

[0137] Method a3:

[0138] Method a3 may include steps A1 to A2:

[0139] Step A1: The first device sends timer indication information; correspondingly, the second device receives the timer indication information. The timer indication information is used to indicate the duration of the first timer, and the duration of the first timer indicated by the timer indication information may be the duration of the first timer suggested by the first device. The specific content of step A1 can refer to method a2, and the repeated parts will not be repeated.

[0140] Step A2: The second device sends timer configuration information; correspondingly, the first device receives the timer configuration information. The timer configuration information is used to configure the duration of the first timer. The specific content of step A2 can refer to method a1, and the repeated parts will not be repeated.

[0141] The duration of the first timer configured by the timer configuration information and the duration of the first timer indicated by the timer indication information may be the same as or different from each other. This is described below with an example.

[0142] In some examples, the timer configuration information may be information confirming the duration of the first timer indicated by the timer indication information (e.g., acknowledgement (ACK) information 1). In this case, the duration of the first timer configured by the timer configuration information is the same as the duration of the first timer indicated by the timer indication information. For example, the timer indication information in step A1 includes 5ms, indicating that the duration of the first timer suggested by the first device is 5ms. The timer configuration information in step A2 is ACK information 1, indicating that the second device agrees to configure the duration of the first timer to 5ms.

[0143] In some other examples, the timer configuration information includes the duration of the first timer. In this case, the duration of the first timer in the timer configuration information may be the duration of the first timer indicated by the timer indication information, or may be the duration of the first timer re-determined by the second device; that is, the duration of the first timer configured by the timer configuration information and the duration of the first timer indicated by the timer indication information are the same or different. For example, the timer indication information in step A1 includes 5ms, indicating that the duration of the first timer suggested by the first device is 5ms. If the second device agrees to configure the duration of the first timer to 5ms, the timer configuration information in step A2 may include 5ms. For another example, the timer indication information in step A1 includes 5ms, indicating that the duration of the first timer suggested by the first device is 5ms. If the second device does not agree to configure the duration of the first timer to 5ms, and configures the duration of the first timer to 6ms, the timer configuration information in step A2 may include 6ms.

[0144] Through method a3, the duration of the first timer is determined by negotiation between the first device and the second device, so that a suitable duration of the first timer can be obtained. Further, based on the duration of the first timer, repeated reporting of DSR can be effectively avoided, thereby avoiding waste of uplink resources caused by repeated reporting of DSR, saving uplink resources, and reducing signaling overhead.

[0145] Method a4:

[0146] Method a4 may include steps B1 to B2:

[0147] Step B1: The first device sends timer indication information; correspondingly, the second device receives the timer indication information. The specific content of step B1 can refer to method a2, and the repeated parts will not be repeated.

[0148] The timer indication information is used to indicate multiple candidate durations of the first timer. Exemplarily, the timer indication information includes multiple candidate durations of the first timer. For example, the multiple candidate durations include: 4ms, 5ms, and 6ms.

[0149] Step B2: The second device sends timer configuration information; correspondingly, the first device receives the timer configuration information. The timer configuration information is used to configure the duration of the first timer. The specific content of step B2 can refer to method a1, and the repeated parts will not be repeated.

[0150] The duration of the first timer configured by the timer configuration information is one of multiple candidate durations. For example, the multiple candidate durations include: 4ms, 5ms and 6ms. The timer configuration information includes 5ms, indicating that the duration of the first timer configured by the timer configuration information is 5ms.

[0151] Through method a4, the duration of the first timer is determined by negotiation between the first device and the second device, so that a suitable duration of the first timer can be obtained. Further, based on the duration of the first timer, repeated reporting of DSR can be effectively avoided, thereby avoiding waste of uplink resources caused by repeated reporting of DSR, saving uplink resources, and reducing signaling overhead.

[0152] It should be understood that the timer configuration information and timer indication information in methods a1 to a4 may also have other names as long as they have the same function, and this application does not impose any restrictions on this.

[0153] Mode a5: The duration of the first timer is related to the minimum remaining scheduling delay of the data in the LCG. In this way, the first device can determine the duration of the first timer according to the minimum remaining scheduling delay of the data in the LCG; in other words, the duration of the first timer is determined according to the minimum remaining scheduling delay of the data in the LCG.

[0154] In some implementations, the duration of the first timer is the minimum remaining scheduling delay of the data in the LCG. Exemplarily, the duration of the first timer is the minimum remaining scheduling delay of the data in the LCG when the first timer is started. For example, if the remaining scheduling delay of data 1 in the LCG is 7 ms and the remaining scheduling delay of data 2 in the LCG is 9 ms when the first timer is started, the duration of the first timer is 7 ms.

[0155] In some other implementations, the duration of the first timer is not only related to the minimum remaining scheduling delay of the data in the LCG, but also to other factors (for example, the processing time of the first device). Exemplarily, the duration of the first timer is the difference between the minimum remaining scheduling delay of the data in the LCG when the first timer is started and the processing time of the first device starting the first timer. For example, if when the first timer is started, the remaining scheduling delay of data 1 in the LCG is 7ms, the remaining scheduling delay of data 2 in the LCG is 9ms, and the processing time of the first device starting the first timer is 1ms, then the duration of the first timer is 6ms.

[0156] Optionally, in mode a5, the first timer may be associated with the LCG.

[0157] Through method a5, the first device can determine the appropriate duration of the first timer according to the minimum remaining scheduling delay within the LCG, thereby effectively avoiding repeated reporting of DSR, avoiding waste of uplink resources caused by repeated reporting of DSR, saving uplink resources, and reducing signaling overhead.

[0158] Mode a6: The duration of the first timer is related to the minimum remaining scheduling delay of data in the first LCH in the LCG, wherein the first timer is associated with the first LCH. In this way, the first device can determine the duration of the first timer according to the minimum remaining scheduling delay of data in the first LCH; in other words, the duration of the first timer is determined according to the minimum remaining scheduling delay of data in the first LCH.

[0159] The specific content of method a6 can refer to method a5, except that LCG is replaced by the first LCH, which will not be repeated here.

[0160] Through method a6, the first device can determine the appropriate duration of the first timer according to the minimum remaining scheduling delay in the LCH, thereby effectively avoiding repeated reporting of DSR, avoiding waste of uplink resources caused by repeated reporting of DSR, saving uplink resources, and reducing signaling overhead.

[0161] As mentioned above, the first device may determine the delay threshold in various ways, such as way b1, way b2, way b3 or way b4.

[0162] Method b1:

[0163] The second device sends the threshold configuration information; correspondingly, the first device receives the threshold configuration information. The threshold configuration information is used to configure the delay threshold. In this way, the first device can determine the delay threshold according to the threshold configuration information.

[0164] In some possible ways, for the LCG in S301, the second device may configure a delay threshold, and the threshold configuration information includes the delay threshold configured by the second device. For example, if the delay threshold configured by the second device for the LCG is 7ms, the threshold configuration information includes 7ms. According to the threshold configuration information, the first device may determine that the delay threshold of the LCG is 7ms.

[0165] In some other possible ways, for the LCG in S301, the second device may configure multiple values ​​related to the delay threshold, and the threshold configuration information may include the multiple related values. The delay threshold of the LCG is determined based on the multiple values, for example, the delay threshold of the LCG is the maximum value, minimum value or average value of the multiple values. Exemplarily, if the multiple values ​​configured by the second device for the LCG are 7ms, 5ms and 3ms, the threshold configuration information includes 7ms, 5ms and 3ms. If the delay threshold of the LCG is the maximum value of the multiple values, the first device may determine that the delay threshold of the LCG is 7ms.

[0166] In some other possible ways, for each of the N LCHs in the LCG in S301, the second device may configure a value related to the delay threshold, and a total of N values ​​may be configured, where N is a positive integer. The N LCHs may be part or all of the LCHs in the LCG. The threshold configuration information may include the N values. The delay threshold of the LCG is determined based on the N values, for example, the delay threshold of the LCG is the maximum value, minimum value or average value of the N values. Exemplarily, the LCG includes LCH 1 and LCH 2. If the value related to the delay threshold configured by the second device for LCH 1 is 7ms, and the value related to the delay threshold configured by the second device for LCH 2 is 5ms, the threshold configuration information may include 7ms and 5ms. If the delay threshold of the LCG is the maximum value of the N values, the first device may determine that the delay threshold of the LCG is 7ms.

[0167] The second device may actively send the threshold configuration information to the first device, or may send the threshold configuration information to the first device based on the request of the first device, and this application does not limit this. The threshold configuration information may be carried in a traditional message or in a new message, and this application does not limit this. Exemplarily, the threshold configuration information may be carried in an RRC message, MACCE, or downlink control information (DCI).

[0168] Optionally, before sending the threshold configuration information, the second device may determine the delay threshold. Exemplarily, the second device may determine the delay threshold based on the service information corresponding to the LCG. The service information may be obtained by the second device from at least one of the following: a service request from the first device, a QoS flow establishment request, or auxiliary information reported by the first device. The second device determines the delay threshold by determining the delay information of the data in the LCG based on the service information. For example, the service information includes: the PDB of the service and the data volume of the service. If the PDB of the service is 10ms, and the second device determines that it takes at least 7ms to transmit the service based on the data volume of the service, the first device may determine that the delay threshold is between 7 and 10ms.

[0169] Through manner b1, the first device can quickly and accurately determine the delay threshold according to the threshold configuration information.

[0170] Mode b2: The first device sends the threshold indication information; correspondingly, the second device receives the threshold indication information. The threshold indication information is used to indicate the delay threshold. That is, in mode b2, the first device can determine the delay threshold by itself and report the determined delay threshold to the second device.

[0171] In some possible ways, for the LCG in S301, the first device may determine a delay threshold, and the threshold indication information includes the delay threshold determined by the first device. For example, if the delay threshold determined by the first device for the LCG is 7ms, the threshold indication information includes 7ms.

[0172] In some other possible ways, for the LCG in S301, the first device may determine M values ​​related to the delay threshold, where M is an integer greater than or equal to 2. The threshold indication information may include the M values. The delay threshold of the LCG is related to the M values, for example, the delay threshold of the LCG is the maximum value, minimum value or average value of the M values. Exemplarily, if the M values ​​determined by the first device for the LCG are 7ms, 5ms and 3ms, then the threshold indication information includes 7ms, 5ms and 3ms. If the delay threshold of the LCG is the maximum value of the M values, then the delay threshold of the LCG is 7ms.

[0173] In some other possible ways, for each of the P LCHs in the LCG in S301, the first device may determine a value related to the delay threshold, and determine a total of P values, where P is a positive integer. The P LCHs may be part or all of the LCHs in the LCG. The threshold indication information may include the P values. The delay threshold of the LCG is related to the P values, for example, the delay threshold of the LCG is the maximum value, minimum value or average value of the P values. Exemplarily, the LCG includes LCH 1 and LCH 2. If the value related to the delay threshold determined by the first device for LCH 1 is 7ms, and the value related to the delay threshold determined by the first device for LCH 2 is 5ms, then the threshold indication information may include 7ms and 5ms. If the delay threshold of the LCG is the maximum value of the P values, then the delay threshold of the LCG is 7ms.

[0174] The first device may actively send the threshold indication information to the second device, or may send the threshold indication information to the second device based on the request or instruction of the second device, and this application does not limit this. The threshold indication information may be carried in a traditional message or in a new message, and this application does not limit this. Exemplarily, the threshold indication information may be carried in UAI, MAC CE or UCI.

[0175] Through mode b2, the first device can determine the delay threshold by itself, so as to obtain the delay threshold quickly and accurately. In addition, the first device can send threshold indication information for indicating the delay threshold to the second device, so that the second device can manage the first device accordingly.

[0176] Method b3:

[0177] Method b3 includes steps C1 to C2:

[0178] Step C1: The first device sends threshold indication information; correspondingly, the second device receives the threshold indication information. The threshold indication information is used to indicate the delay threshold. The delay threshold indicated by the threshold indication information is the delay threshold recommended by the first device. The specific content of step C1 can refer to method b2, and the repeated parts will not be repeated.

[0179] Step C2: The second device sends the threshold configuration information; correspondingly, the first device receives the threshold configuration information. The threshold configuration information is used to configure the delay threshold. The specific content of step C2 can refer to method b1, and the repeated parts will not be repeated.

[0180] The delay threshold configured by the threshold configuration information and the delay threshold indicated by the threshold indication information may be the same or different. This is illustrated below with an example.

[0181] In some examples, the threshold configuration information may be information confirming the delay threshold indicated by the threshold indication information (e.g., ACK information 2). In this case, the delay threshold configured by the threshold configuration information is the same as the delay threshold indicated by the threshold indication information. For example, the threshold indication information in step C1 includes 7ms, indicating that the delay threshold recommended by the first device is 7ms. The threshold configuration information in step C2 is ACK information 2, indicating that the second device agrees to configure the delay threshold to 7ms.

[0182] In other examples, the delay threshold configured by the threshold configuration information may be the delay threshold indicated by the threshold indication information, or may be the delay threshold re-determined by the second device; that is, the delay threshold configured by the threshold configuration information and the delay threshold indicated by the threshold indication information are the same or different. For example, the threshold indication information in step C1 includes 7ms, indicating that the delay threshold recommended by the first device is 7ms. If the second device agrees to configure the delay threshold to 7ms, the threshold configuration information in step C2 may include 7ms. For another example, the threshold indication information in step C1 includes 7ms, indicating that the delay threshold recommended by the first device is 7ms. If the second device does not agree to configure the delay threshold to 7ms, and reconfigures the delay threshold to 8ms, the threshold configuration information in step C2 may include 8ms.

[0183] Through mode b3, the delay threshold is determined by negotiation between the first device and the second device, so that a suitable delay threshold can be obtained, and then the reporting of the DSR can be reasonably triggered according to the delay threshold.

[0184] Method b4:

[0185] Mode b4 includes: Steps D1 to D2:

[0186] Step D1: The first device sends threshold indication information; correspondingly, the second device receives the threshold indication information. The specific content of step D1 can refer to mode b2, and the repeated parts will not be repeated.

[0187] The threshold indication information is used to indicate multiple candidate values ​​of the delay threshold. Exemplarily, the threshold indication information includes multiple candidate values ​​of the delay threshold. For example, the multiple candidate values ​​include: 3ms, 5ms and 7ms.

[0188] Step D2: The second device sends the threshold configuration information; correspondingly, the first device receives the threshold configuration information. The specific content of step D2 can refer to method b1, and the repeated parts will not be repeated.

[0189] The delay threshold configured by the threshold configuration information is one of multiple candidate values. For example, the multiple candidate values ​​include: 3ms, 5ms and 7ms. The threshold configuration information includes 7ms, indicating that the delay threshold configured by the threshold configuration information is 7ms.

[0190] Through mode b4, the delay threshold is determined by negotiation between the first device and the second device, so that a suitable delay threshold can be obtained, and then the reporting of the DSR can be reasonably triggered according to the delay threshold.

[0191] It should be understood that the threshold configuration information and threshold indication information in methods b1 to b4 may also have other names as long as they have the same function, and this application does not impose any restrictions on this.

[0192] Some possible ways are Figure 3 The method shown also includes S303:

[0193] S303: The first device sends information including DSR (eg, MAC CE including DSR); correspondingly, the second device receives the information including DSR.

[0194] Optionally, the first device may use available uplink resources to send information including DSR. Figure 4 As shown, at the 4th ms, the first device may use the PUSCH to send information including the DSR.

[0195] In some possible ways, after triggering the reporting of DSR, if the first device has no available uplink resources, the first device may send an SR; accordingly, the second device receives the SR. The SR is used to request scheduling of uplink resources for the first device. Optionally, after receiving the SR, the second device may allocate uplink resources to the first device and notify the first device of the allocated uplink resources. This application does not limit the specific process of allocating resources and notifying resources. Then, the first device may use the allocated uplink resources to report information containing the DSR (e.g., a MAC CE containing the DSR).

[0196] Optionally, within the first time period after the DSR is triggered, if the first device has no available uplink resources, the first device sends an SR. The first time period may be preset, for example, specified by a protocol, or included in the factory settings of the first device, or included in the SIM card of the first device; or, the first time period may be determined by the first device; or, the first time period may be obtained by the first device from other devices (for example, the second device).

[0197] Through this method, the first device can report the DSR in a timely manner, so that the second device can schedule resources for the first device in a timely manner, reduce data transmission delay, and improve communication quality.

[0198] Combine the following Figure 4 and Figure 5 In the example shown, the first condition includes condition 3 and condition 2. Figure 3 The application of the method shown is described.

[0199] like Figure 4As shown, the PDB of data 1 in LCG is 10ms, the delay threshold is 7ms, and the duration of the first timer is 5ms. The duration of the first timer can be determined by any of the methods a1 to a4. Data 1 in LCG arrives at the cache of the first device at 0ms. Between 0 and 3ms, the remaining scheduling delay of data 1 is greater than the delay threshold, and the first device does not trigger the reporting of DSR. At 3ms, the remaining scheduling delay of data 1 is equal to the delay threshold, the first device triggers the reporting of DSR, starts the first timer, and waits for the generation of a MAC CE containing DSR. At 4ms, the first device generates a MAC CE containing DSR, and uses PUSCH to report the MAC CE containing DSR, and the triggering of DSR reporting is cancelled. Between 4 and 8ms, the remaining scheduling delay of data 1 is less than the delay threshold, but because the first timer has been running, the first device does not trigger the reporting of DSR, and will not generate a MAC CE containing DSR. At 8 ms, the remaining scheduling delay of data 1 is less than the delay threshold, and the first timer stops running due to timeout. The first device can trigger the reporting of DSR, start the first timer, and wait for the generation of a MAC CE containing DSR. At 9 ms, the first device generates a MAC CE containing DSR and uses PUSCH to report the MAC CE containing DSR, and the triggering of DSR reporting is canceled. Between 9 and 13 ms, the remaining scheduling delay of data 1 is less than the delay threshold, but because the first timer is already running, the first device does not trigger the reporting of DSR, and does not generate a MAC CE containing DSR.

[0200] like Figure 5 As shown, the PDB of data 1 in LCG is 10ms, and the delay threshold is 7ms. The duration of the first timer can be determined by method a5 or method a6. Data 1 in LCG arrives at the cache of the first device at 0ms. Between 0 and 3ms, the remaining scheduling delay of data 1 is greater than the delay threshold, and the first device does not trigger the reporting of DSR. At 3ms, the remaining scheduling delay of data 1 is equal to the delay threshold, the first device triggers the reporting of DSR, starts the first timer, and waits for the generation of a MAC CE containing DSR. The duration of the first timer is the remaining scheduling delay of data 1, that is, 7ms, so the first device will not trigger the reporting of DSR again between 3 and 10ms. At 4ms, the first device generates a MAC CE containing DSR, and uses PUSCH to report the MAC CE containing DSR, and the triggering of DSR reporting is cancelled. At 7 and 9ms, the first device uses PUSCH to transmit data.

[0201] like Figure 4 and Figure 5 As shown, through Figure 3According to the method shown, when the remaining scheduling delay of the data in the LCG is less than or equal to the delay threshold, the first device reports the DSR only on a partially available PUSCH, thereby avoiding repeated reporting of the DSR, and further avoiding the waste of uplink resources caused by repeated reporting of the DSR, saving uplink resources, and reducing signaling overhead.

[0202] In view of this, an embodiment of the present application provides a communication method. Figure 6 A flow chart corresponding to the communication method provided in the embodiment of the present application. Figure 6 The method is illustrated by taking the first device and the second device as the execution subjects of the interaction as an example, but the present application does not limit the execution subjects of the interaction. For example, the first device can be a terminal, or a module applied to the terminal, such as a circuit, a chip, a chip system or a processor, or a logical node, a logical module or software that can realize all or part of the terminal functions; the second device can also be an access network device, or a module applied to the access network device, such as a circuit, a chip, a chip system or a processor, or a logical node, a logical module or software that can realize all or part of the access network device functions. Figure 6 As shown, the method includes:

[0203] S601: The first device triggers reporting of the first DSR according to the remaining scheduling delay of the first data in the LCG, and starts a second timer.

[0204] Optionally, when the remaining scheduling delay of the first data is less than the delay threshold and the second timer is not running, the first device may trigger the reporting of the first DSR; or, when the remaining scheduling delay of the first data is less than or equal to the delay threshold and the second timer is not running, the first device may trigger the reporting of the first DSR. For the specific content of the first data, please refer to the description of the data in the first condition where the remaining scheduling delay is less than the delay threshold in S301; for the specific content of the second timer, please refer to Figure 3 The description of the first timer in the method shown is just to replace the first timer with the second timer, which is not repeated here. Before triggering the reporting of the first DSR, the first device can determine the delay threshold, and there are many ways to determine it. For example, the first device can determine the delay threshold by any of the above methods b1 to b4, which is not repeated here.

[0205] The specific content of the first device starting the second timer can refer to the description of "the first device starts the first timer" in S302, except that the first timer is replaced by the second timer, which will not be repeated here. When using the second timer, the first device needs to determine the duration of the second timer, and the content of the determination will be described in the following methods d1 to d6, which will not be expanded here.

[0206] There may be multiple timings for the first device to start the second timer, for example, timing b1, timing b2 or timing b3.

[0207] Timing b1: When the reporting of the first DSR is triggered, the first device may start the second timer.

[0208] Timing b2: When generating the information including the first DSR, the first device may start the second timer.

[0209] Timing b3: When reporting the information including the first DSR, the first device may start the second timer.

[0210] The specific contents of the timings b1 to b3 may refer to the timings a1 to a3 in S302 respectively, except that the DSR is replaced by the first DSR and the first timer is replaced by the second timer, which will not be described again here.

[0211] In the present application, the first DSR may be used to report information related to data delay. The specific content of the first DSR may refer to the explanation of DSR in the explanation of related terms above, which will not be repeated here.

[0212] S602: When the second condition is met, the first device triggers reporting of the second DSR.

[0213] The second condition at least includes condition a: the remaining scheduling delay of the second data in the LCG is less than the remaining scheduling delay of the first data. For example, if the remaining scheduling delay of the first data is 5.5 ms and the remaining scheduling delay of the second data is 4.5 ms, the first device may determine that condition a is satisfied. It should be understood that the second condition may include only condition a, or may include other conditions while including condition a.

[0214] It should be understood that in S601, the remaining scheduling delay of the first data is less than or equal to the delay threshold. Therefore, when condition a is met, the remaining scheduling delay of the second data is less than the delay threshold.

[0215] In some possible ways, the second timer is associated with the LCG, and one LCG may be associated with one second timer. In this case, the first data and the second data are data in the same LCG.

[0216] In some other possible ways, the second timer is associated with an LCG within an LCG, and one LCH can be associated with one second timer. In this case, the first data and the second data are data within the same LCH (hereinafter referred to as the second LCH) within the same LCG. That is to say, the second condition also includes at least: the first data and the second data are data within the second LCH. For example, the LCG includes LCH 3 and LCH 4, LCH 3 is associated with the second timer 1, and LCH 4 is associated with the second timer 2. When there is data 1 in LCH 3 whose remaining scheduling delay is less than the delay threshold, and the second timer 1 is not running, the first device can trigger the reporting of the first DSR and start the second timer 1. If there is data 4 in LCH 3 afterwards, and the remaining scheduling delay of data 4 is less than the remaining scheduling delay of data 1, the first device can trigger the reporting of the second DSR.

[0217] In the present application, the second DSR may be used to report information related to data delay. The specific content of the second DSR may refer to the explanation of DSR in the explanation of related terms above, which will not be repeated here.

[0218] S603: The first device restarts the second timer.

[0219] Optionally, when restarting the second timer, the second timer may be in one of the following states: running state, timeout state, paused state or non-running state. The manner in which the first device restarts the second timer is the same as the "manner of starting the first timer" in S601, except that start is replaced by restart, and the first timer is replaced by the second timer, which will not be described in detail here.

[0220] The first device may restart the second timer at various times, for example, time c1, time c2 or time c3.

[0221] Timing c1: when the reporting of the second DSR is triggered, the first device restarts the second timer.

[0222] Timing c2: When generating the information including the second DSR, the first device restarts the second timer.

[0223] Timing c3: When reporting the information including the second DSR, the first device restarts the second timer.

[0224] The specific contents of the moments c1 to c3 may refer to the moments a1 to a3 in S302 respectively, except that DSR is replaced by the second DSR, the first timer is replaced by the second timer, and start is replaced by restart, which will not be repeated here.

[0225] pass Figure 6In the method shown, when the reporting of the first DSR is triggered according to the first data, the first device can run the second timer. During the operation of the second timer, the reporting of the first DSR will not be triggered, thereby avoiding repeated reporting of the DSR, and further avoiding the waste of uplink resources caused by repeated reporting of the DSR, saving uplink resources, and reducing signaling overhead. In the case where the remaining scheduling delay of the second data in the LCG is less than the remaining scheduling delay of the first data, the first device can trigger the reporting of the second DSR regardless of whether the second timer is running, thereby avoiding the failure to trigger the reporting of the DSR when there is data in the LCG that is more urgent than the first data.

[0226] As mentioned above, the first device may determine the duration of the second timer in various ways, such as way d1, way d2, way d3, way d4, way d5 or way d6.

[0227] Mode d1: The second device sends timer configuration information; correspondingly, the first device receives the timer configuration information. The timer configuration information is used to configure the duration of the second timer.

[0228] Mode d2: The first device sends timer indication information; correspondingly, the second device receives the timer indication information. The timer indication information is used to indicate the duration of the second timer. That is, in mode d2, the first device can determine the duration of the second timer by itself, and report the determined duration of the second timer to the second device.

[0229] Method d3:

[0230] Method d3 includes steps E1 to E2:

[0231] Step E1: The first device sends timer indication information; correspondingly, the second device receives the timer indication information. The timer indication information is used to indicate the duration of the second timer. The duration of the second timer indicated by the timer indication information may be the duration of the second timer suggested by the first device.

[0232] Step E2: The second device sends timer configuration information; correspondingly, the first device receives the timer configuration information. The timer configuration information is used to configure the duration of the second timer. The duration of the second timer configured by the timer configuration information is the same as or different from the duration of the second timer indicated by the timer indication information.

[0233] Method d4:

[0234] Method d4 includes steps F1 to F2:

[0235] Step F1: The first device sends timer indication information; correspondingly, the second device receives the timer indication information. The timer indication information is used to indicate multiple candidate durations of the second timer.

[0236] Step F2: The second device sends timer configuration information; correspondingly, the first device receives the timer configuration information. The timer configuration information is used to configure the duration of the second timer. The duration of the second timer configured by the timer configuration information is one of multiple candidate durations.

[0237] Mode d5: The duration of the second timer is related to the minimum remaining scheduling delay of the data in the LCG.

[0238] Mode d6: The duration of the second timer is related to the minimum remaining scheduling delay of data in the second LCH in the LCG, wherein the second timer is associated with the second LCH.

[0239] The specific contents of methods d1 to d6 can refer to methods a1 to a6 respectively, except that the first timer is replaced by the second timer, and the first LCH is replaced by the second LCH, which will not be repeated here. In the case where the duration of the second timer is determined by any of methods d1 to d4, the duration of the second timer started in S601 and the duration of the second timer restarted in S603 can be the same. In the case where the duration of the second timer is determined by methods d5 or d6, the duration of the second timer started in S601 is related to the remaining scheduling delay of the first data, and the duration of the second timer restarted in S603 is related to the remaining scheduling delay of the second data. For example, in S601, when the remaining scheduling delay of the first data is 7ms when the second timer is started, the duration of the second timer is 7ms; in S603, when the remaining scheduling delay of the second data is 5ms when the second timer is restarted, the duration of the second timer is 5ms.

[0240] Some possible ways are Figure 6 The method shown also includes S604:

[0241] S604: The first device sends information including the second DSR (eg, a MAC CE including the second DSR); correspondingly, the second device receives the information including the second DSR.

[0242] The specific content of S604 can refer to S303, except that DSR is replaced by the second DSR, which will not be repeated here.

[0243] Through this method, the first device can report the DSR in a timely manner, so that the second device can schedule resources for the first device in a timely manner, reduce data transmission delay, and improve communication quality.

[0244] Combine the following Figure 7 The example shown is for Figure 6 The application of the method shown is described.

[0245] like Figure 7 As shown, the PDB of data 1 in LCG is 10ms, and the delay threshold is 7ms. The duration of the first timer can be determined by method d5 or d6. Data 1 in LCG arrives at the cache of the first device at 0ms. Between 0 and 3ms, the remaining scheduling delay of data 1 is greater than the delay threshold, and the first device does not trigger the reporting of DSR. At 3ms, the remaining scheduling delay of data 1 is equal to the delay threshold, the first device triggers the reporting of the first DSR, starts the second timer, and waits for the generation of the MAC CE containing the first DSR. The duration of the second timer is the remaining scheduling delay of data 1, that is, 7ms. Between 3 and 10ms, if no data with a remaining scheduling delay smaller than the remaining scheduling delay of data 1 arrives at the cache of the first device, the first device will no longer trigger the reporting of DSR. At 4ms, the first device generates a MAC CE containing the first DSR, and uses PUSCH to report the MAC CE containing the first DSR, and the triggering of the DSR reporting is cancelled. At 4.5ms, data 4 in the LCG arrives at the cache of the first device. The remaining scheduling delay of data 4 is 5ms, which is less than the remaining scheduling delay of data 1, 5.5ms. The first device triggers the reporting of the second DSR, restarts the second timer, and waits for the generation of a MAC CE containing the second DSR. The duration of the second timer is the remaining scheduling delay of data 4, that is, 5ms. From 4.5 to 9.5ms, if no data with a remaining scheduling delay smaller than the remaining scheduling delay of data 4 arrives at the cache of the first device, the first device will not trigger the reporting of the DSR. At 7ms, the first device generates a MAC CE containing the second DSR, and uses PUSCH to report the MAC CE containing the second DSR, and the triggering of the DSR reporting is canceled. At 9ms, the first device uses PUSCH to transmit data.

[0246] like Figure 7 As shown, through Figure 6 In the method shown, when the reporting of the first DSR is triggered according to data 1, the first device can run the second timer. During the operation of the second timer, the reporting of the first DSR will not be triggered, thereby avoiding repeated reporting of the DSR, and further avoiding the waste of uplink resources caused by repeated reporting of the DSR, saving uplink resources, and reducing signaling overhead. When the remaining scheduling delay of data 4 in the LCG is less than the remaining scheduling delay of data 1, the first device can trigger the reporting of the second DSR regardless of whether the second timer is running, thereby avoiding the failure to trigger the reporting of the DSR when there is data in the LCG that is more urgent than data 1.

[0247] Based on the same technical concept as the above method embodiment, the embodiment of the present application provides a corresponding communication device, which can be used to perform the functions of the relevant steps in the above method embodiment. The function can be implemented by hardware, can be implemented by software, or can be implemented by hardware executing the corresponding software. The hardware or software includes one or more modules corresponding to the above functions. The communication device can be a terminal, or can be a module in a terminal (such as a circuit or a chip), or can be a logical node, a logical module or software that can realize all or part of the functions of a terminal or an access network device; or the communication device can be an access network device or a module in an access network device (such as a circuit or a chip), or can be a logical node, a logical module or software that can realize all or part of the functions of an access network device.

[0248] In a possible implementation, the structure of the communication device provided in the embodiment of the present application is as follows: Figure 8 As shown, the communication device 800 includes a processing unit 802. Optionally, the communication device further includes an interface unit 801. The functions of each unit in the communication device 800 are introduced below.

[0249] The interface unit 801 is used to input and / or output information. The input information can be replaced by receiving information, and the output information can be replaced by sending information.
