Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, but is not limited thereto, and particularly relates to communication methods, communication devices, communication apparatuses, and storage media.

Background Art

[0002] Currently, the continuous emergence of new Internet applications such as next-generation augmented reality (AR) or virtual reality (VR) places higher demands on wireless communication technologies, promoting the continuous evolution of wireless communication technologies to meet the needs of applications. Currently, cellular mobile communication technology is in the stage of evolution of next-generation technologies. One important feature of the new generation of technologies is to support flexible configurations of various business types. Different business types have different requirements for wireless communication technologies. For example, the enhanced Mobile Broad Band (eMBB) service type focuses on aspects such as large bandwidth and high rate, the Ultra Reliable Low Latency Communication (URLLC) service type focuses on aspects such as high reliability and low latency, and the massive Machine Type Communication (mMTC) service type focuses on the aspect of big data. Therefore, the new wireless communication system requires a flexible and configurable design to support the transmission of various business types.

[0003] In the research of wireless communication technologies, satellite communication is an important aspect of the future development of wireless communication technologies. Satellite communication is communication in which a terrestrial wireless communication device uses a satellite as a relay. A satellite communication system consists of a satellite part and a ground part. The characteristics of satellite communication are that the communication range is wide, and communication is possible between any two points within the coverage of the radio waves transmitted by the satellite, and it is less affected by terrestrial disasters (high reliability). Satellite communication has the following advantages as a supplement to the current terrestrial cellular communication system.

[0004] Coverage expansion: In areas that cannot be covered by current cellular communication systems, or where coverage costs are high, such as the ocean, deserts, and remote areas, satellite communication can solve communication problems. Emergency communications: In extreme situations such as earthquakes or other disasters where cellular communication infrastructure is unavailable, satellite communications can be used to quickly establish communication connections. Providing industry applications: For example, for services sensitive to long-distance transmission delays, satellite communication can reduce service transmission delays.

[0005] In future wireless communication systems, it is expected that satellite communication systems and terrestrial cellular communication systems will achieve deep convergence, enabling intelligent connectivity between all things. However, the high speed of satellite movement makes it difficult to effectively ensure the reliability of data exchange in satellite communication scenarios.

[0044] Referring to Figure 1, this is a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include a plurality of user equipment 110 and a plurality of base stations 120.

[0045] Here, user equipment 110 may refer to a device that provides voice and / or data communication to the user. User equipment 110 is capable of communicating with one or more core networks via a Radio Access Network (RAN), and user equipment 110 may be a UE such as a sensor device, a mobile phone (also called a "cellular" phone), and a computer Internet of Things UE, and may be, for example, a fixed, portable, pocket, handheld, computer-integrated, or vehicle-mounted device.

[0046] The base station 120 may be a network-side device in a wireless communication system. Here, the wireless communication system may be a 4th generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system, or it may be a 5G system, also known as a new wireless system or a 5G NR system. Alternatively, the wireless communication system may be a system of the next generation after the 5G system. Here, the access network in the 5G system may be called an NG-RAN (New Generation-Radio Access Network).

[0047] Here, base station 120 may be an evolved base station (eNB) used in a 4G system. Alternatively, base station 120 may be a base station (gNB) using a centralized-distributed architecture in a 5G system.

The central unit is configured with a protocol stack for the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer, while the distributed units are configured with a physical (PHY) layer protocol stack. Embodiments of this disclosure do not limit the specific implementation of base station 120.

[0048] A wireless connection can be established between the base station 120 and the user equipment 110 via a wireless interface. In different embodiments, the wireless interface may be a wireless interface based on fourth-generation mobile communication network technology (4G) standards, or a wireless interface based on fifth-generation mobile communication network technology (5G) standards, for example, the wireless interface may be a new wireless, or the wireless interface may be a wireless interface based on the next-generation mobile communication network technology standards after 5G.

[0050] Here, the above-mentioned user equipment can be considered as the terminal device in the following embodiment.

[0051] In some embodiments, the wireless communication system may further include a network management device 130.

[0052] Each of the multiple base stations 120 is connected to a network management device 130. Here, the network management device 130 may be a core network device in a wireless communication system, for example, a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the network management device may be another core network device, such as a Serving Gateway (SGW), Public Data Network Gateway (PGW), Policy and Charging Rules Function (PCRF), or Home Subscriber Server (HSS). The embodiments of the network management device 130 are not limited to those of the embodiments of this disclosure.

[0053] To better understand the technical concepts described in any embodiment of this disclosure, we will first explain the content related to satellite communications.

[0054] In satellite communications, the long signal transmission distance between the transmitter and receiver results in longer data transmission times, which are transmission delays. To compensate for these transmission delays, time offsets are introduced during transmission (including uplink and downlink transmissions).

[0055] In one embodiment, the uplink and downlink transmission timings on the base station side are aligned. As shown in Figure 2, the timings of the base station's (gNB) uplink transmission (gNB UL) and downlink transmission (gNB DL) are aligned; that is, the frames marked as n in gNB UL and gNB DL in Figure 2 are aligned. Furthermore, referring to Figure 2, there is a transmission delay between gNB UL and the downlink transmission to the user equipment (UE DL). The UE's uplink transmission timing advance (TA) must take into account the transmission delay from the UE to the satellite, thereby enabling uplink transmissions from different UEs to reach the gNB within a predetermined time range.

[0056] In another embodiment, the uplink and downlink transmission timings on the base station side are not aligned. As shown in Figure 3, the uplink and downlink transmissions of the gNB are not aligned; that is, the frames marked as n in gNB UL and gNB DL in Figure 3 are not aligned, and there is a time-domain offset (gNB DL-UL frame timing shift), and there is a transmission delay between the gNB downlink transmission (gNB DL) and the UE downlink transmission (UE DL). For a similar UE uplink transmission timing advance (Time Advance, TA), the transmission delay from the terminal to the satellite must be taken into account, thereby allowing uplink transmissions from different UEs to reach the gNB within a predetermined time range. In this embodiment, when considering the timing advance, the time-domain timing shift between the gNB uplink and downlink transmissions (gNB DL-UL frame timing shift) is taken into account.

[0057] In one embodiment, the time offset is applicable to, but not limited to, transmissions of at least one of the following: Physical Uplink Shared Channel (PUSCH) transmissions scheduled by Downlink Control Information (DCI), Hybrid Automatic Repeat reQuest (HARQ) feedback information transmissions, and Media Access Control (MAC) Control Element (CE) transmissions. In one embodiment, the time offset includes a timing offset (Koffset). For example, when the timing offset is applied to the transmission of HARQ feedback information, if the last slot of the PDSCH received by the UE is slot n, the UE transmits a Physical Uplink Control Channel (PUCCH) containing the corresponding HARQ-ACK information in slot n + K1 + Koffset, where K1 is the slot number. Furthermore, the timing offset is applied to the DCI's PUSCH, and if the UE receives a DCI that schedules a PUSCH transmission in slot n, and the DCI indicates that the slot offset is K2, then the UE is set to slot n × (2μ PUSCH / 2μ PDCCH )+K2+Koffset transmits PUSCH, where μ PUSCH and μ PDCCH These represent the subcarrier spacing settings for PUSCH and the Physical Downlink Shared Channel (PDSCH), respectively.

[0058] In one embodiment, the possible values ​​of Koffset are determined by the transmission delay from the UE to the network device (e.g., base station). In a satellite communications scenario, the possible values ​​of Koffset will differ if different satellites are in different orbits at different altitudes.

[0059] In satellite communications scenarios, the range of time offsets used in different scenarios may vary. In one embodiment, the range of time offsets is determined by orbital information and the positional information of a reference point. In one embodiment, the range of time offsets is greater than or equal to 0 and less than or equal to 450 ms.

[0060] In one embodiment, a single time offset range supports all satellite communication scenarios. In this embodiment, the granularity of such a time offset range is large, resulting in additional signaling overhead.

[0061] In one embodiment, different time offset ranges support different satellite communication scenarios. In this embodiment, it is necessary to define different application scenarios and corresponding value ranges.

[0062] As shown in Figure 4, an embodiment of the present disclosure provides a communication method performed by an NTN network device, the method comprising the following step 41.

[0063] Step S41: Transmit first information including timing range information for indicating the timing range of the time offset, and first instruction information for indicating the time offset determined from the timing range.

[0064] The methods provided by the embodiments of this disclosure are applicable to NTN, which includes, but is not limited to, networks that communicate using satellites as relays.

[0065] The methods provided by the embodiments of this disclosure may be performed by NTN network devices, which include access network devices or core network devices.

[0066] In one embodiment, the access network device may be, but is not limited to, various base stations, such as a 2G base station, a 3G base station, a 4G base station, a 5G base station, or other advanced base stations.

[0067] In one embodiment, the core network device may be various physical or logical entities, such as a mobility management entity or a serving gateway. When the communication method is performed by the core network device, the core network device transmits first information to a base station, and the base station forwards the first information to the UE.

[0068] In one embodiment, the time offset includes a timing offset (Koffset).

[0069] The communication method provided by the embodiments of this disclosure may be performed by an NTN network device and may include the step of transmitting first information to the UE, which includes timing range information indicating a timing range for Koffset and first instruction information indicating a Koffset determined from the timing range.

[0070] In one embodiment, Koffset may be used to compensate for timing deviations in the uplink and downlink of the UE.

[0071] In one embodiment, Koffset is greater than or equal to the timing advance. For example, the timing advance is 10 milliseconds (ms), and therefore Koffset is 12 ms.

[0072] This improves the reliability of data transmission between NTN network devices (e.g., base stations) and UEs by compensating for transmission delays in transmissions between NTN network devices and UEs through a time offset.

[0073] In one embodiment, the timing range information includes a first timing range or a second timing range.

[0074] In one embodiment, the first timing range can be considered a unified value range. For example, the base station transmits a unified timing range of 0-1000ms or 0-500ms to some or all UEs within the cell. For example, the unified timing range supports all application scenarios of satellite communications.

[0075] In another embodiment, the second timing range can be considered as any one of a predetermined number of timing ranges defined in the communication protocol. For example, as shown in the table below, the second timing range may be 0-100ms, 101-200ms, 201-300ms, 301-400ms, or 401-500ms.

[0076] [Table 1]

[0077] Here, a predetermined number of second timing ranges may be stored in advance at the base station. When the base station transmits the first information, it may carry one of these second timing ranges and transmit it to the UE. Here, the predetermined number may be one or more. Here, the predetermined number of second timing ranges does not have to be the ranges shown in Table 1. For example, they may be 0 to 200 ms, 201 to 400 ms, or 401 to 600 ms, etc.

[0078] Note that each element in Table 1 is independent, and although these elements are shown illustratively in the same table, not all elements must exist simultaneously as shown in the table. The value of each element is independent of any other element in Table 1. Therefore, as those skilled in the art will understand, the possible values ​​for each element in Table 1 are all independent embodiments.

[0079] In one embodiment, the first timing range can be divided into one or more second timing ranges. For example, the first timing range is 0 to 500 ms, and the first timing range can be divided into five second timing ranges, which are 0 to 100 ms, 101 to 200 ms, 201 to 300 ms, 301 to 400 ms, and 401 to 500 ms, respectively.

[0080] In another embodiment, the first timing range is greater than or equal to the second timing range. For example, the first timing range is 0 to 500 ms, and the second timing range is 301 to 400 ms.

[0081] In another embodiment, the first timing range and the second timing range are two ranges that do not have a specific relationship. For example, the first timing range is 0 to 200 ms, and the second timing range is 150 ms to 250 ms.

[0082] In one embodiment, the first instruction information is a first predetermined number of bits. Here, the first predetermined number of bits may be one or more bits.

[0083] For example, the communication protocol predefines the correspondence between the first instruction information and the Koffset timing range. For instance, the Koffset timing range is 0 to 100 ms. For example, the first instruction information may be indicated by four bits. If the first instruction information is "0000", it indicates that the Koffset is 0 ms; if the first instruction information is "0001", it indicates that the Koffset is 10 ms; and if the first instruction information is "0010", it indicates that the Koffset is 20 ms. Alternatively, the first instruction information may be indicated by eight bits. If the first instruction information is "00000000", it indicates that Koffset is 0ms; if the first instruction information is "00000001", it indicates that Koffset is 1ms; if the first instruction information is "00000010", it indicates that Koffset is 2ms; and if the first instruction information is "00000011", it indicates that Koffset is 3ms.

[0084] In embodiments of this disclosure, the timing range and first instruction information in the UE satellite communication scene can be communicated via NTN's network device, thereby enabling the UE to determine a time offset suitable for the current satellite communication scene based on the first instruction information. This improves the accuracy of the time offset determined in different satellite communication scenes and, consequently, the reliability of transmission between NTN's network device and the UE.

[0085] Embodiments of the present disclosure provide a communication method performed by an NTN network device, the communication method comprising the step of transmitting high-level signaling or physical layer signaling carrying first information.

[0086] In one embodiment, high-level signaling includes radio resource control (RRC) signaling or media access control (MAC) control element (CE) signaling.

[0087] In one embodiment, physical layer signaling includes Downlink Control Information (DCI) signaling.

[0088] In another embodiment, the NTN network device may transmit the first information by conventional system messages or dedicated system messages.

[0089] In the embodiments of this disclosure, NTN's network device may carry the first information transmission by high-level signaling, physical layer signaling, and system messages, thereby improving the utilization efficiency of high-level signaling, physical layer signaling, or system messages, and reducing signaling overhead.

[0090] As those skilled in the art will understand, the methods provided by the embodiments of this disclosure may be performed independently or in conjunction with some of the methods of the embodiments of this disclosure or some of the methods of the related technology.

[0091] As shown in Figure 5, the communication method provided by the embodiments of this disclosure is performed by an NTN network device and includes the following steps:

[0092] Step S51: Transmit first information including reference timing information indicating a reference timing time, a first timing range, and first instruction information, where the reference timing time and the first instruction information indicate a time offset determined from the first timing range.

[0093] In some embodiments of this disclosure, the first instruction information is the first instruction information in step S41, the first timing range is the first timing range in step S41, and the time offset is the time offset in step S41.

[0094] The communication method provided by the embodiments of this disclosure is performed by an NTN network device and may include the step of determining reference timing information based on satellite ephemeris information.

[0095] Here, the satellite's ephemeris information may refer to the satellite's orbital information. The satellite's ephemeris information may indicate the satellite's orbital state at different times. In this way, NTN's network device can determine the altitude range in which the satellite is located based on the satellite's information or its orbital information, and further determine the reference timing information based on the altitude range. Here, the altitude of the satellite's altitude range is positively correlated with the reference timing time indicated by the reference timing information.

[0096] Thus, the embodiments of this disclosure determine a precise reference timing time based on the actual trajectory of the satellite, thereby determining a precise time offset.

[0097] In one embodiment, the reference timing time includes one or more slots. For example, if one slot is 1 ms and the reference timing time includes one slot, the reference timing time is 1 ms; if the reference timing time includes 10 slots, the reference timing time is 10 ms.

[0098] In another embodiment, the reference timing time includes one or more slots corresponding to a predetermined subcarrier spacing (SCS), where the predetermined subcarrier spacing may refer to any SCS. For example, the predetermined SCS may be 15 kHz, 30 kHz, or 240 kHz. Exemplarily, if the predetermined SCS is 15 kHz, one symbol is 66.67 microseconds (us), and if one slot contains 14 symbols, one slot is approximately 1 ms. If the reference timing time includes one slot corresponding to the predetermined SCS, the reference timing time is 1 ms, and if the reference timing time includes 12 slots corresponding to the predetermined SCS, the reference timing time is 12 ms.

[0099] In another embodiment, the reference timing time may include a plurality of symbols corresponding to a predetermined SCS.

[0100] In one embodiment, the product of the reference timing time and the number indicated by the first instruction information indicates a time offset determined from the first timing range.

[0101] For example, if the first timing range transmitted by the base station to the UE is 0 to 1000 ms, the first instruction information is "0001", the reference timing time indicated by the reference timing information is 10 ms, and the number indicated by the first instruction information is 1 and the reference timing time is 10 ms, then it is determined that the time offset in the 0 to 1000 ms range of the first timing range indicated by the first instruction information and the reference timing time is 10 ms.

[0102] For example, if the first timing range transmitted by the base station to the UE is 0 to 1000 ms, the first instruction information is "0011", the reference timing time indicated by the reference timing information is 10 ms, and the number indicated by the first instruction information is 3 and the reference timing time is 10 ms, then it is determined that the time offset in the first timing range 0 to 1000 ms indicated by the first instruction information and the reference timing time is 30 ms.

[0103] For example, if the first timing range transmitted by the base station to the UE is 0 to 1000 ms, the first instruction information is "0011", the reference timing time indicated by the reference timing information is 100 ms, the number indicated by the first instruction information is 3 and the reference timing time is 100 ms, then the time offset in the first timing range 0 to 1000 ms indicated by the first instruction information and the reference timing time is determined to be 300 ms.

[0104] In embodiments of this disclosure, a first timing range may be transmitted to the UE via NTN's network device to support all application scenarios of satellite communications, and reference timing information and first instruction information may be transmitted to the UE. This allows the UE to specify time offsets in the first timing range with different granularity based on the different reference timing information and first instruction information. In this way, the UE can determine accurate time offsets using a single unified timing range in various application scenarios of satellite communications, thereby improving the reliability of transmission between NTN's network device and the UE in these application scenarios.

[0105] When the first timing range is wide, a large reference timing time can be set, which allows for precise time offsets between NTN network devices and UE transmissions, even with relatively few bits of first instruction information. In this way, the number of bits in the first instruction information can be saved, reducing signaling overhead.

[0106] As those skilled in the art will understand, the methods provided by the embodiments of this disclosure may be performed independently or in conjunction with some of the methods of the embodiments of this disclosure or some of the methods of the related technology.

[0107] As shown in Figure 6, the communication method provided by the embodiments of this disclosure is performed by an NTN network device and includes the following steps:

[0108] Step S61: Transmit first information including a second timing range and first instruction information, or second instruction information and first instruction information indicating the second timing range, or ephemeris information and first instruction information determining the second timing range of the time offset, wherein the first instruction information indicates the time offset determined from the second timing range.

[0109] In some embodiments of this disclosure, the first instruction information is the first instruction information in step S41, the second timing range is the second timing range in step S41, and the time offset is the time offset in step S41.

[0110] In one embodiment, the second instruction information is information of a second predetermined number of bits. Here, the second predetermined number of bits may be one or more bits.

[0111] For example, a communication protocol predefines the correspondence between a second instruction and a second timing range. For instance, if the second instruction is "001", it indicates that the second timing range is 0-100ms; if it is "010", it indicates that the second timing range is 101-200ms; if it is "011", it indicates that the second timing range is 201-300ms; if it is "0100", it indicates that the second timing range is 301-400ms; and if it is "0101", it indicates that the second timing range is 401-500ms. In this way, after receiving the second instruction, the UE can determine the second timing range based on the second instruction.

[0112] In one embodiment, the satellite's ephemeris information may refer to the satellite's orbital information, and the satellite's ephemeris information or orbital information may be used to determine the altitude range in which the satellite is located. Here, the altitude of the satellite's altitude range is positively correlated with the upper and lower limits of the second timing range. For example, if the satellite's altitude is less than 600 kilometers (km), the second timing range is 0 to 40 ms, and if the satellite's altitude is between 600 and 12,000 km, the second timing range is 40 to 600 ms. In this way, after receiving the ephemeris information, the UE can determine the second timing range based on the ephemeris information.

[0113] In one embodiment, ephemeris information may be sent to the UE via a system message. In this way, this embodiment can carry and transmit ephemeris information via a system message, thereby reducing signaling overhead.

[0114] In one embodiment, the communication protocol predefines the correspondence between first instruction information and the time offset in the second timing range. In this way, the first instruction information can be used to specify the time offset in the second timing range.

[0115] For example, if the second timing range transmitted by the base station to the UE is 0 to 100 ms, and the first instruction information is "0001", and the first instruction information "0001" indicates 10, then it is determined that the first instruction information indicates that the time offset in the second timing range 0 to 100 ms is 10 ms.

[0116] For example, if the second timing range transmitted by the base station to the UE is 0 to 100 ms, and the first instruction information is "0101", and the first instruction information "0101" indicates 50, then it is determined that the first instruction information indicates that the time offset in the second timing range of 0 to 100 ms is 50 ms.

[0117] For example, if the second timing range transmitted by the base station to the UE is 101-200ms, and the first instruction information is "0101", and the first instruction information "0101" indicates 50, then it is determined that the first instruction information indicates that the time offset in the second timing range 101-201ms is 150ms.

[0118] For example, if the second timing range transmitted by the base station to the UE is 0 to 100 ms, and the first instruction information is "00000001", and the first instruction information "00000001" indicates 1, then it is determined that the first instruction information indicates that the time offset in the second timing range 0 to 100 ms is 1 ms.

[0119] In embodiments of the present disclosure, NTN's network device may transmit a second timing range corresponding to different satellite communication scenes to the UE, and may also transmit first instruction information to the UE, so that the UE can determine an accurate time offset from the second timing range based on the first instruction information, thereby improving the reliability of transmission between NTN's network device and the UE in different satellite communication scenes.
