[0001] The embodiments of the present application relate to the field of communications, and more specifically, to wireless communication methods and devices. Background Art

[0002] In the New Radio (NR), the signal transmission delay between the terminal device and the network device is very small.

[0049] The wireless communication system 100 may also include a core network device 130 for communicating with the base station, and the core network device 130 may be a 5G core network (5G Core, 5GC) device, for example, an access and mobility management function (Access and Mobility Management Function, AMF), and for example, an authentication server function (Authentication Server Function, AUSF), and for example, a user plane function (User Plane Function, UPF), and for example, a session management function (Session Management Function, SMF). Optionally, the core network device 130 may also be an evolved packet core (Evolved Packet Core, EPC) device of the LTE network, for example, a session management function + a data gateway (Session Management Function + Core Packet Gateway, SMF + PGW-C) device of the core network. It should be understood that SMF + PGW-C can simultaneously implement the functions that SMF and PGW-C can implement. In the process of network evolution, the above-mentioned core network device may also be called other names, or a new network entity may be formed by dividing the functions of the core network, which is not limited to the embodiments of the present application.

[0050] The functional units in the communication system 100 may also establish connections through next generation (NG) network interfaces to achieve communication.

[0053] Figure 2 A schematic diagram of the architecture of another communication system provided in an embodiment of the present application.

[0054] like Figure 2 As shown, it includes a terminal device 1101 and a satellite 1102, and wireless communication can be performed between the terminal device 1101 and the satellite 1102. The network formed between the terminal device 1101 and the satellite 1102 can also be called NTN. Figure 2 In the architecture of the communication system shown, the satellite 1102 may have the function of a base station, and the terminal device 1101 and the satellite 1102 may communicate directly. In the system architecture, the satellite 1102 may be referred to as a network device. In some embodiments of the present application, the communication system may include multiple network devices 1102, and each network device 1102 may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0055] Figure 3 A schematic diagram of the architecture of another communication system provided in an embodiment of the present application.

[0056] like Figure 3 As shown, it includes terminal device 1201, satellite 1202 and base station 1203. Wireless communication can be performed between terminal device 1201 and satellite 1202, and satellite 1202 and base station 1203 can communicate with each other. The network formed by terminal device 1201, satellite 1202 and base station 1203 can also be called NTN. Figure 3 In the architecture of the communication system shown in FIG. 1 , the satellite 1202 may not have the function of a base station, and the communication between the terminal device 1201 and the base station 1203 needs to be transferred through the satellite 1202. In this system architecture, the base station 1203 can be called a network device. In some embodiments of the present application, the communication system may include multiple network devices 1203, and each network device 1203 may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application. The network device 1203 may be Figure 1 The network device 120 in.

[0057] It should be understood that the satellite 1102 or satellite 1202 includes but is not limited to:

[0058] Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, High Elliptical Orbit (HEO) satellites, etc. Satellites can use multiple beams to cover the ground. For example, a satellite can form dozens or even hundreds of beams to cover the ground. In other words, a satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers to ensure satellite coverage and improve the system capacity of the entire satellite communication system.

[0059] As an example, the altitude range of LEO can be 500km~1500km, the corresponding orbital period can be about 1.5 hours~2 hours, the signal propagation delay of single-hop communication between users can generally be less than 20ms, the maximum satellite visible time can be 20 minutes, the signal propagation distance of LEO is short and the link loss is small, and the transmission power requirement of user terminals is not high. The orbital altitude of GEO can be 35786km, the rotation period around the earth can be 24 hours, and the signal propagation delay of single-hop communication between users can generally be 250ms.

[0060] It should be noted that Figures 1 to 3 It is only to illustrate the system to which the present application is applicable in the form of an example. Of course, the method shown in the embodiment of the present application can also be applied to other systems. In addition, the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship. It should also be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0061] To facilitate understanding of the present application, the fifth generation mobile communication technology (5-Generation, 5G) new radio (New Radio, NR) buffer status report (Buffer Status Report, BSR) process is described below.

[0062] In NR, the UE informs the serving network device of the UE's uplink buffer data volume through BSR, so that the network device can schedule the UE according to the data volume information provided by the UE.

[0063] Optionally, in order to save BSR reporting overhead, a group reporting method is adopted. For example, the UE reports the BSR based on the LCG.

[0064] Optionally, each uplink logical channel corresponds to a logical channel group (Logical Channel Group, LCG), and multiple uplink logical channels can correspond to the same LCG.

[0065] Optionally, the correspondence between the logical channel and the LCG is configured by the network device through RRC signaling.

[0066] Optionally, each UE in NR can support up to 8 LCGs.

[0067] Optionally, the BSR is carried by a BSR media access control (MAC) control element (CE).

[0068] BSR triggering conditions include but are not limited to the following:

[0069] 1. Uplink data arrives on a logical channel with a higher priority of the UE. In this case, a regular BSR is triggered.

[0070] 2. The padding part of the uplink resources allocated to the UE after carrying other uplink data can carry the BSR MAC CE. In this case, a padding BSR will be issued.

[0071] 3. The retransmission BSR timer retxBSR-Timer times out, and there is currently at least one uplink logical channel with uplink data to be sent, then a regular BSR will be triggered.

[0072] 4. When the periodicBSR-Timer times out, a periodic BSR (Periodic BSR) is triggered.

[0073] If multiple logical channels trigger a Regular BSR simultaneously, each of these logical channels triggers a separate Regular BSR.

[0074] If the terminal device triggers a regular BSR, but the terminal device has no uplink resources for transmitting new data or the uplink resources allocated to the terminal device for transmitting new data cannot carry the data of the uplink logical channel that triggers the regular BSR, the terminal device triggers an SR.

[0075] In other words, when uplink data arrives at the UE but the UE has no uplink resources for data transmission, the UE needs to send the data to the network device by requesting uplink scheduling.

[0076] Figure 4 A schematic flow chart of a method 200 for requesting uplink scheduling according to an embodiment of the present application is shown. The method 200 can be interactively executed by a terminal device and a network device. Figure 4 The terminal device shown in FIG. 1 may be a terminal device such as Figures 1 to 3 The terminal equipment shown in Figure 4 The network devices shown in can be Figures 1 to 3 The access network equipment shown in .

[0077] like Figure 4 As shown, the method 200 may include:

[0078] S210, User Equipment (UE) sends a Scheduling Request (SR) to request uplink resources from a network device.

[0079] S220, the network device receives the SR and determines that the UE needs uplink resources for transmitting uplink data, but the network device does not know how much uplink data the UE needs to send. Therefore, the network device can allocate enough physical uplink shared channel (PUSCH) resources to the UE for the UE to send a buffer status report (BSR).

[0080] S230, the UE sends a BSR on the PUSCH resources allocated by the network device to inform the network device of the amount of data that the UE needs to send.

[0081] S240: The network device allocates appropriate PUSCH resources for uplink data transmission to the UE according to the BSR reported by the UE.

[0082] S220, the UE transmits uplink data on the PUSCH resources allocated by the network device.

[0083] In the New Radio (NR), the signal transmission delay between the terminal device and the network device is very small. The waiting time from the time the terminal device has uplink data to the time the terminal device sends this data to the network device is generally short, which has little impact on service delay.

[0084] Compared with the cellular network used by traditional NR, the signal propagation delay between the terminal device and the satellite in the non-terrestrial communication network (NTN) is greatly increased. Therefore, when uplink data arrives at the terminal device, but the terminal device does not have uplink resources for data transmission, it takes a relatively long time to send this data to the network, which causes the service delay to increase significantly and affects the user experience.

[0085] In the embodiment of the present application, the uplink scheduling delay can be reduced by studying the uplink configuration authorization.

[0086] Among them, the main idea of ​​using uplink configuration grant to reduce uplink scheduling delay is to configure uplink configuration grant (Configured Grant, CG) for UE. When UE triggers BSR, BSR report can be performed through CG. Based on this, the time of UE sending SR and waiting for network equipment to respond to uplink grant can be saved. However, when using CG to achieve timely BSR reporting, when UE has no uplink data transmission resources, it will cause waste of system resources.

[0087] To facilitate the understanding of this application, the uplink CG is explained below.

[0088] For each uplink CG configuration, the network device configures a limited number of HARQ process numbers for it, and the UE uses these uplink HARQ processes in a polling manner to perform uplink transmission on the uplink CG resources.

[0089] For example, the following two types of CGs can be included:

[0090] Configured grant Type 1:

[0091] The network equipment RRC configures all transmission resources and transmission parameters including time domain resources, frequency domain resources, the period of time domain resources, modulation and coding scheme (MCS), number of repetitions, frequency hopping, number of hybrid automatic repeat request (HARQ) processes, etc. After receiving the Radio Resource Control (RRC) configuration, the terminal device can immediately use the configured transmission parameters to perform PUSCH transmission on the configured time and frequency resources.

[0092] Configured grant Type 2 (CG):

[0093] A two-step resource configuration method is adopted. First, the network device RRC configures the transmission resources and transmission parameters including the period, number of repetitions, frequency hopping, number of HARQ processes, etc. of the time domain resources; then the Physical Downlink Control Channel (PDCCH) scrambled by the Configured Scheduling Radio Network Temporary Identifier (CS-RNTI) activates the second type of PUSCH transmission based on the configuration authorization, and configures other transmission resources and transmission parameters including time domain resources, frequency domain resources, MCS, etc. at the same time. When the UE receives the RRC configuration parameters, it cannot immediately use the resources and parameters configured by the configuration parameters for PUSCH transmission, but must wait until the corresponding PDCCH is received to activate and configure other resources and parameters before PUSCH transmission can be performed.

[0094] If the UE has no data to be sent on the PUSCH resources of the first and second CG types, the UE will not send anything on the CG resources.

[0095] The present application further provides a wireless communication method, which can not only reduce the uplink scheduling delay, but also improve the utilization efficiency of system resources.

[0096] Figure 5 A schematic flow chart of a wireless communication method 300 according to an embodiment of the present application is shown, and the method 300 can be executed by a terminal device or a network device. Figure 5 The terminal device shown in FIG. 1 may be a terminal device such as Figures 1 to 3 The terminal equipment shown in Figure 5 The network devices shown in can be Figures 1 to 3 The access network device shown in FIG. 3 is a terminal device. The method 300 is described below by taking the terminal device as an example.

[0097] like Figure 5 As shown, the method 300 may include:

[0098] S310, when the first timer times out, the terminal device activates the uplink configuration authorization CG.

[0099] In other words, the terminal device can implicitly activate or deactivate the uplink CG.

[0100] In other words, only when the uplink CG is in an activated state can the UE use the uplink CG for PUSCH transmission. For example, the UE uses the uplink CG for BSR transmission.

[0101] Based on the above technical solutions, on the one hand, transmitting data through the uplink CG can reduce the uplink scheduling delay; on the other hand, controlling whether to activate the uplink CG through the first timer can improve the utilization efficiency of system resources.

[0102] That is, the wireless communication method provided in the embodiment of the present application can not only reduce the uplink scheduling delay, but also improve the utilization efficiency of system resources.

[0103] In some embodiments of the present application, the method 300 may further include:

[0104] Starting or restarting the first timer;

[0105] During the operation of the first timer, the uplink CG is in a deactivated state.

[0106] For example, when the terminal device receives a dynamically scheduled uplink grant (UL grant), the first timer is started or restarted.

[0107] For another example, when the terminal device receives a dynamically scheduled uplink grant (UL grant) during the operation of the first timer, the first timer is started or restarted. In other words, when the uplink CG is in a deactivated state and the terminal device receives a dynamically scheduled uplink grant (UL grant), the first timer is started or restarted.

[0108] For another example, when the uplink CG is in an activated state and the terminal device receives a dynamically scheduled uplink authorization (UL grant), the first timer is started or restarted.

[0109] For another example, when the uplink CG is in an activated state, the terminal device receives the uplink authorization, and the uplink authorization can carry all the data to be transmitted by the terminal device, the uplink CG is deactivated and the first timer is started or restarted.

[0110] For another example, when the uplink CG is in an activated state, if the UE receives a UL grant indicating dynamic scheduling from a network device, and the UL grant can carry all data to be transmitted by the UE, the UE deactivates the CG. At the same time, the UE starts or restarts the first timer.

[0111] For another example, the initial state of the uplink CG is a deactivated state; upon receiving the first configuration information for the uplink CG, the first timer is started or restarted. Optionally, the uplink CG is a first type CG, and the first configuration information is a radio resource control RRC configuration for the uplink CG. Optionally, the uplink CG is a second type CG, and the first configuration information is a physical downlink control channel PDCCH configured by the radio resource control RRC for the uplink CG.

[0112] In other words, the UE may maintain the first timer in the following manner:

[0113] Mode 1: If the initial state of the uplink CG is deactivated, the first timer is started when the UE obtains the CG resource configuration. For type 1 CG, when the UE receives the RRC signaling for the CG configuration, the UE starts the first timer. For type 2 CG, when the UE receives the PDCCH for the CG time-frequency resource configuration, the UE starts the first timer.

[0114] Mode 2: When the UE receives an uplink grant scheduled by the PDCCH, the UE starts or restarts the first timer.

[0115] In some embodiments of the present application, the method 300 may further include:

[0116] The terminal device receives second configuration information sent by the network device, where the second configuration information is used to configure the duration of the first timer.

[0117] For example, the uplink CG is a first type CG, and the second configuration information is carried in the radio resource control RRC configuration for the uplink CG. For another example, the uplink CG is a second type CG; the second configuration information is carried in the radio resource control RRC configuration for the uplink CG, or the second configuration information is carried in the physical downlink control channel PDCCH of the RRC configuration for the uplink CG.

[0118] For example, the UE receives configuration information for configuring CG-related parameters sent by the network device, where the configuration information for configuring CG-related parameters includes at least one of the following information:

[0119] The resource periodicity of the uplink CG;

[0120] The number of uplink HARQ processes reserved for the uplink CG (nrofHARQ-Processes);

[0121] The time-frequency resource configuration of the uplink CG; or

[0122] Second configuration information used to configure the first timer.

[0123] Among them, for type1 CG, the time and frequency resource configuration of the uplink CG is configured by RRC signaling; for type2 CG, the time and frequency resource configuration of the uplink CG is indicated by PDCCH; the first timer is used to activate the uplink CG.

[0124] In some embodiments of the present application, the method 300 may further include:

[0125] Receive first indication information sent by a network device, where the first indication information is used to indicate the initial state of the uplink CG.

[0126] For example, the uplink CG is a first type CG, and the first indication information is carried in the radio resource control RRC configuration for the uplink CG. For another example, the uplink CG is a second type CG; the first indication information is carried in the radio resource control RRC configuration for the uplink CG, or the first indication information is carried in the physical downlink control channel PDCCH of the RRC configuration for the uplink CG.

[0127] In some embodiments of the present application, the initial state of the uplink CG is a predefined default state.

[0128] In other words, the UE can determine the initial state of the uplink CG in the following manner:

[0129] Method 1: The network device displays the instructions.

[0130] For example, if it is a type1 CG, the network device indicates in the CG configuration of RRC whether the initial state of the CG is an activated state or a deactivated state; for another example, if it is a type2 CG, the network device indicates in the CG configuration of RRC or in the PDCCH that configures the CG time and frequency resources whether the initial state of the CG is an activated state or a deactivated state.

[0131] Method 2: Define the default state.

[0132] In some embodiments of the present application, the initial state is an activated state or a deactivated state.

[0133] Figure 6 It is a schematic timing diagram of activating or deactivating the uplink CG provided in an embodiment of the present application.

[0134] like Figure 6As shown, the initial state of the uplink CG is a deactivated state. If the terminal device receives the first configuration information for the uplink CG, the terminal device starts the first timer. If the terminal device receives a PDCCH indicating dynamic scheduling, the terminal device restarts the first timer. If the first timer times out, the terminal device activates the uplink CG.

Optionally, the uplink CG is a second type CG, and the first configuration information is a physical downlink control channel PDCCH configured for the radio resource control RRC for the uplink CG.

[0157] In other words, the terminal device can explicitly activate or deactivate the uplink CG.

[0158] That is, the UE performs activation / deactivation operations on the CG according to the instructions of the network device.

[0159] For example, if the network device instructs to activate the first type of CG, the UE activates the first type of CG, and the UE can use the first type of CG for PUSCH transmission. For another example, if the network device instructs to deactivate the first type of CG, the UE deactivates the first type of CG, and the UE cannot use the first type of CG for PUSCH transmission.

[0160] In other words, the network device sends second indication information to the terminal device, where the second indication information is used to indicate activation or deactivation of the first type of configuration authorization CG.

[0167] In some embodiments of the present application, the second indication information is carried in at least one of the following: radio resource control RRC signaling, media access control element MAC CE or physical downlink control channel PDCCH.

[0168] In other words, the UE can determine the initial state of the uplink CG in the following manner:

[0169] Method 1: The network device displays the instructions.

[0170] For example, the network device indicates in the CG configuration of RRC that the initial state of the CG is an activated state or a deactivated state.

[0171] Method 2: Define the default state as activated or deactivated.

[0172] In some embodiments of the present application, the terminal device receives configuration information for configuring the first type CG sent by the network device, and the configuration information for configuring the first type CG includes at least one of the following information:
