[0001] The present invention relates to the field of communication technology and, in particular, to a random access method, a configuration indicating method, a random access device, a configuration indicating device, a communication device, and a computer-readable storage medium.

Prerequisites for creating the invention

[0002] With the development of communication technology, there has become a need for communication between base stations and terminals anywhere on the earth's surface. However, the base stations in the existing network are located on the earth's surface, which limits the provision of base stations because it is difficult to completely cover the earth's surface with base stations located on the earth's surface. Therefore, the possibility of including satellites in the systems to increase the coverage area is being considered.

[0003] In a terrestrial network, a base station may transmit a timing advance (abbreviated TA, Timing Advance) to the terminal so that the uplink signal frame transmitted by the terminal matches the downlink signal frame transmitted by the base station.

[0004] However, in the case of non-terrestrial network (abbreviated NTN, Non-Terrestrial Network) communication using satellites, since the satellite is in outer space and moves at high speed, when the base station communicates with the terminal via the satellite, a large delay occurs , and the timing advance is determined according to this delay, so the timing advance is relatively large, which may cause some problems.

The essence of the invention

[0005] In view of this, to solve the technical problems of the prior art, embodiments of the present invention provide a random access method, a configuration indicating method, a random access device, a configuration indicating device, a communication device, and a computer-readable storage medium.

[0006] According to a first aspect of embodiments of the present invention, a random access method is provided. The method is applied to a terminal and includes, in response to the terminal autonomously determining a timing advance, receiving feedback information from a base station during a random access procedure in accordance with the first reception timing information; and, in response to the terminal's non-autonomous determination of the timing advance, receiving feedback information from the base station during the random access procedure in accordance with the second reception timing information. The first reception timing information is different from the second reception timing information.

[0007] According to a second aspect of embodiments of the present invention, a configuration indication method is provided. The method is applied to a base station and includes transmitting to the terminal indication information containing first reception timing information and second reception timing information. The indication information is used to indicate to the terminal that, in response to the terminal's autonomous timing advance determination, it should receive feedback information from the base station during the random access procedure in accordance with the first receive timing information, and in response to the non-autonomous timing advance determination, receive feedback information. communication from the base station during the random access procedure in accordance with the second reception timing information. The first reception timing information is different from the second reception timing information.

[0008] According to a third aspect of embodiments of the present invention, a random access device is provided. An apparatus is applied to a terminal and includes a feedback receiving module configured to, in response to the terminal autonomously determining a timing advance, receive feedback information from a base station during a random access procedure in accordance with the first reception timing information, and in response to the non-autonomous determining by the terminal a timing advance to receive feedback information from the base station during the random access procedure in accordance with the second reception timing information. The first reception timing information is different from the second reception timing information.

[0009] According to a fourth aspect of embodiments of the present invention, an apparatus for indicating a configuration is provided. The apparatus is applied to a base station and includes a command transmission module configured to transmit indication information including first reception timing information and second reception timing information to the terminal. The indication information is used to indicate to the terminal that, in response to the terminal's autonomous determination of timing advance, it should receive feedback information from the base station during the random access procedure in accordance with the first receive timing information, and in response to the non-autonomous determination of timing advance, receive feedback information. communication from the base station during the random access procedure in accordance with the second reception timing information. The first reception timing information is different from the second reception timing information.

[0010] According to a fifth aspect of embodiments of the present invention, a communication device is provided. The communication device includes a processor and memory for storing instructions executed by the processor. The processor is configured to implement instructions for executing a random access method according to any of the above embodiments of the invention and/or a configuration indicating method according to any of the above embodiments.

[0011] According to a sixth aspect of embodiments of the present invention, a computer-readable storage medium is provided. The computer-readable storage medium contains computer programs stored therein that, when executed by a processor, cause the execution of steps of a random access method in accordance with any of the above-mentioned embodiments of the invention and/or a configuration indication method in accordance with any of the above-mentioned embodiments of the invention.

[0012] According to embodiments of the present invention, the base station may indicate different reception timing information in the case where the terminal determines the timing advance autonomously and in the case where the terminal determines the timing advance non-autonomously, so that the terminal can receive feedback information from the base station. station during the random access procedure based on the first receive timing information in case the terminal autonomously determines timing advance, and receive feedback information from the base station during the random access procedure based on the second receive timing information in case the terminal does not autonomously determine synchronization advance. The first reception timing information is different from the second reception timing information.

[0013] That is, the terminal can receive feedback information from the base station based on different reception timing information during the random access procedure in the case of autonomous timing advance determination and in the case of non-autonomous timing advance determination.

[0014] In the case where the timing advance is determined autonomously by the terminal, since the delay error to be compensated for is small, the terminal can relatively accurately determine the moment when the feedback information arrives from the base station, so that the feedback information is received after an offset of a relatively large delay, and the duration of the time window for receiving feedback information may be shorter to reduce the time consumption of the random access procedure.

[0015] In the case that the timing advance is determined autonomously by the terminal, since the delay error to be compensated is large, it is difficult for the terminal to accurately determine the moment when the feedback information arrives from the base station, so that the feedback information is received after an offset of a relatively small delay, and the duration of the time window for receiving feedback information may be longer to ensure that feedback information from the base station can be received, thereby successfully completing the random access procedure.

Detailed description

[0027] The technical solutions in the embodiments of the present invention are described in detail below with reference to the accompanying drawings in the embodiments of the present invention. It will be appreciated that the described embodiments are only some embodiments of the present invention and not all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without performing creative work fall within the scope of the present invention.

[0028] FIG. 1 is a flowchart of a random access method according to an embodiment of the present invention. The method shown in embodiments of the invention can be applied to terminals in non-terrestrial networks, and these terminals include, but are not limited to, electronic devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal may serve as a user equipment for communicating with a base station, and the base station may be a base station located on the earth's surface in a non-terrestrial network, or a network device located in space in a non-terrestrial network, such as a satellite, an aerial platform and the like. Below is a description for the case where the network device is a satellite.

[0029] As shown in FIG. 1, the random access method may include step S101.

[0030] In step S101, feedback information is received from the base station during the random access procedure in accordance with the first reception timing information in response to the terminal autonomously determining the timing advance, and feedback information is received from the base station during the random access procedure in accordance with with the second reception timing information in response to the terminal's non-autonomous timing advance determination.

[0031] The first reception timing information is different from the second reception timing information.

[0032] It should be noted that the first reception timing information and/or the second reception timing information in all embodiments of the present invention may be configured by the base station for the terminal or may be determined by the terminal itself, which may be determined according to needs and is not limited to the present invention.

[0033] In a non-terrestrial network, regardless of whether the terminal communicates with a base station located on the earth's surface or with a satellite serving as the base station, the communication signal must be transmitted to the satellite. Since the satellite is in space, it takes a long time to transmit the communication signal to the satellite, which results in a high communication delay between the terminal and the base station, which can reach a maximum of 541.46 ms.

[0034] To compensate for communication delay in a non-terrestrial network, the terminal may perform compensation based on timing advance during the communication process, and the compensation process generally includes the following two methods.

[0035] The first method is for the terminal to autonomously determine the timing advance, which is used in a situation where the terminal can determine its own location. The terminal can calculate the delay to be compensated according to the distance from the terminal to the satellite, which applies to the regenerative mode of the satellite, that is, the satellite used as a base station. Alternatively, the terminal may calculate the delay to be compensated according to the distance from the terminal to the satellite and the distance or delay between the satellite and the base station, which applies to a base station located on the earth's surface.

[0036] The delay, which must be compensated and determined by the terminal, can be used as a timing advance, and the timing advance can be reported to the base station during a random access procedure, for example, in a Msg3 or MsgA message carried in the random access procedure. When the terminal communicates with the base station, all timing advances may be corrected, or the overall timing advance (called common TA) broadcast by the network may be first received, and then partial correction may be made, such as correcting the differences between all timing advances and the common ahead of synchronization.

[0037] The second method is for the terminal to autonomously determine the timing advance, which is used in a situation where the terminal cannot determine its own location. The terminal may receive the overall timing advance transmitted by the network and then adjust the overall timing advance when communicating with the base station. Alternatively, the terminal does not adjust the timing advance, but the network adjusts the overall timing advance. For example, the satellite adjusts the overall timing advance.

[0038] For example, the distance from the satellite to a reference point on the earth's surface (which may be a projection of the satellite's position onto the earth's surface) is d0, the distance from the satellite to the terminal is d1, the distance from the satellite to the base station is d0F, and the speed of light c. Thus, in the regenerative mode of the satellite, the total timing advance is equal to the round-trip delay from the satellite to the ground reference point, that is, equal to 2*d0/c. When the terminal communicates with a base station on the earth's surface, the total timing advance is equal to the sum of the round-trip delay from the satellite to the reference point on the earth's surface and the round-trip delay from the satellite to the base station on the earth's surface, i.e. 2*(d0+d0_F)/c.

[0039] It can be seen that the delays compensated by the terminal based on the two methods mentioned above are different.

[0040] In the case where the timing advance is determined autonomously by the terminal, since the position of the terminal can be determined, the correspondingly determined timing advance is relatively accurate, and the compensated delay is relatively accurate. Typically, the error between the actual delay and the compensated delay can be within 1 ms.

[0041] In the case where the timing advance is determined non-autonomously by the terminal, since the timing advance is not determined according to the position of the terminal, compensation is performed based on the overall timing advance. The total timing advance does not include the distance d1 from the satellite to the terminal, but only the distance d0 from the satellite to the reference point on the earth's surface, so that the actual delay and the compensated delay have a large error, which is positively correlated with the difference between d1 and d0. For a cell with a coverage radius of 3500 km, the error can reach even 20.6 ms.

[0042] In order to compensate for the delay during the random access procedure, the terminal needs to perform compensation in accordance with the above-mentioned offline timing advance detection method or the above-mentioned offline timing advance detection method. That is, during a random access procedure when information such as messages Msg1, Msg3, MsgA or the like is transmitted, it is required to carry forward all timing advances or carry forward the difference between all timing advances and the total timing advance in the offline timing advance determination method. . Alternatively, the overall timing advance is required to be brought forward in the on-line timing advance determination method, or the overall timing advance is adjusted by the network.

[0043] In addition, when the terminal receives feedback information from the base station during the random access procedure, the feedback information needs to be received in accordance with the above-mentioned delay. For example, for a random access response transmitted by a base station, the terminal may receive feedback information after transmitting the Msg1 message. However, due to the presence of the above delay, the feedback information can not be transmitted to the terminal until after the above delay after the terminal sends Msg1, so after the terminal sends Msg1, it needs to wait at least the above delay before receiving the information feedback transmitted by the base station.

[0044] From the above content, it can be seen that when the terminal autonomously determines the timing advance and when the terminal autonomously determines the timing advance, the delays that need to be compensated are different. In the case where the timing advance is determined autonomously by the terminal, the delay to be compensated is determined according to the distance d1 between the terminal and the satellite. In the case where the timing advance is determined autonomously by the terminal, the delay that needs to be compensated is indicated to the terminal by the satellite or base station and is determined in accordance with the distance d0 from the satellite to a reference point on the earth's surface.

[0045] In general, d1 is not equal to d0, where d1 is the actual distance between the terminal and the satellite. Therefore, the compensated delay determined by d1 is relatively accurate, but the compensated delay determined by d0 has a large error. If the terminal only receives feedback information according to one type of reception timing information, in order to adapt to the above two compensation methods, it must match the large delay error situation and the relatively fine delay situation. Therefore, d0 is used to calculate the delay that needs to be compensated to determine the reception of feedback information, so that the terminal needs to receive feedback information earlier, and the reception duration must be relatively longer to ensure that feedback information can be received in case , if the delay error is large.

[0046] According to embodiments of the present invention, the base station may indicate different reception timing information in the case where the timing advance is determined autonomously by the terminal and in the case where the timing advance is determined non-autonomously by the terminal. That is, the terminal can receive feedback information from the base station during the random access procedure based on the first reception timing information in the case that the timing advance is determined autonomously by the terminal, and receive feedback information from the base station during the random access procedure based on the second information about reception synchronization in the event that the synchronization advance is determined non-autonomously by the terminal. The first reception timing information is different from the second reception timing information.

[0047] That is, the terminal can receive feedback information from the base station based on various reception timing information such as messages Msg2, Msg4, etc., in the case where the timing advance is determined autonomously by the terminal and in the case where the timing advance synchronization is determined by the terminal independently.

[0048] For example, the above-mentioned reception timing information may contain two pieces of information, i.e. offset and duration of the time window. In the case where the timing advance is determined autonomously by the terminal, since the delay error to be compensated for is small, the terminal can relatively accurately determine the moment when the feedback information from the base station reaches it, so that the feedback information can be received after an offset of a relatively large delay. The duration of the time window for receiving feedback information may be relatively short to reduce the time consumption of the random access procedure.

[0049] In the case where the timing advance is determined non-autonomously by the terminal, since the delay error to be compensated is large, it is difficult for the terminal to accurately determine the moment when the feedback information from the base station reaches it, so that the feedback information can be received after the offset from relatively small delay. The duration of the time window for receiving feedback information may be relatively large to ensure that feedback information from the base station can be received, thereby successfully completing the random access procedure.

[0050] In some embodiments, the first reception timing information comprises a first offset of a first time window for receiving a random access response relative to a first reception time and/or a first duration of the first time window.

[0051] Alternatively, the second reception timing information comprises a second offset of the second time window for receiving the random access response relative to the second reception time and/or a second duration of the second time window.

[0052] The first offset is different from the second offset, and/or the first duration is different from the second duration.

[0053] In an embodiment of the invention, the first reception timing information and the second reception timing information may comprise two parts, that is, an offset and/or a time window duration.

[0054] In particular, the first reception timing information may comprise a first offset of the first time window for receiving the random access response relative to the first reception time and/or a first duration of the first time window. The second reception timing information may comprise a second offset of the second time window for receiving the random access response relative to the second reception time and/or a second duration of the second time window. The first offset may be different from the second offset, and/or the first duration may be different from the second duration.

[0055] The first reception timing information may comprise only the first offset, or only the first duration of the first time window, or contain both the first offset and the first duration of the first time window. The second reception timing information may comprise only the second offset, or only the second duration of the second time window, or contain both the second offset and the second duration of the second time window.

[0056] For example, the first receive timing information includes a first offset and a first duration of a first time window, and the second receive timing information includes a second offset and a second duration of a second time window.

[0057] In the case where the timing advance is determined autonomously by the terminal, since the delay error to be compensated for is small, the terminal can relatively accurately determine the moment when the feedback information from the base station reaches it, so that the feedback information can be received after the first offsets with a relatively long delay. The first duration of the first time window for receiving feedback information may be relatively short to reduce the time consumption of the random access procedure.

[0058] In the case where the timing advance is determined non-autonomously by the terminal, since the delay error to be compensated is large, it is difficult for the terminal to accurately determine the moment when the feedback information from the base station reaches it, so that the feedback information can be received after the second offset with a relatively short delay, and the second duration of the second time window for receiving feedback information may be relatively long to ensure that feedback information from the base station can be received, thereby successfully completing the random access procedure.

[0059] FIG. 2 is a flowchart of a random access method according to an embodiment of the present invention. As shown in FIG. 2, in step S1011, receiving feedback information from the base station during the random access procedure in accordance with the first reception timing information includes the following step S1011:

[0060] In step S1011, random access response information transmitted by the base station is received in the first time window through the nearest physical downlink control channel (PDCCH) opportunity. The first time window is the time window after the first offset relative to the first reception time. And/or receiving feedback information from the base station during the random access procedure in accordance with the second reception timing information includes receiving, in a second time window, random access response information transmitted by the base station, wherein the second time window is a time window after the second offset relative to second appointment time.

[0061] In an embodiment of the invention, in the case where the timing advance is determined autonomously by the terminal, the terminal may receive, in the first time window, random access response information transmitted by the base station via the nearest downlink physical control channel opportunity, and the first time window is the time window after the first offset relative to the first reception time.

[0062] In an embodiment of the invention, in the case where the timing advance is determined non-autonomously by the terminal, the terminal may receive, in a second time window, random access response information transmitted by the base station through the nearest downlink physical control channel opportunity, and the second time window is the time window after the second offset relative to the second reception time.

[0063] In some embodiments, each of the first receive time and the second receive time is a time when the message Msg1 or MsgA for the random access procedure is transmitted in its entirety.

[0064] In an embodiment of the invention, during a 4-step random access procedure, the terminal may receive, in a first time window, random access response information transmitted by the base station via the nearest downlink physical control channel opportunity, and the first time window is a time window window after the first offset since the completion of message Msg1.

[0065] In an embodiment of the invention, during a 2-step random access procedure, the terminal may receive, in a second time window, random access response information transmitted by the base station via the nearest downlink physical control channel opportunity, and the second time window is a time window window after the second offset since the completion of transmission of the MsgA message.

[0066] In some embodiments of the invention, the first offset is greater than the second offset and/or the first duration is less than the second duration.

[0067] In an embodiment of the invention, the first offset may be greater than the second offset, and the first duration may be less than the second duration. Therefore, in the case where the timing advance is determined autonomously by the terminal, the terminal may delay receiving the feedback information by a relatively large first offset, and/or the first duration of the first time window for receiving the feedback information may be relatively short to reduce the time spent in the procedure random access. In the case where the timing advance is determined non-autonomously by the terminal, the terminal may delay receiving the feedback information by a relatively small second offset, and/or the second duration of the second time window for receiving the feedback information may be relatively large to ensure that the feedback information from the base station is received, thus successfully completing the random access procedure.

[0068] In some embodiments of the invention, the first offset is equal to 2*d1/c or equal to 2*(d1+d0_F)/c, and the second offset is equal to 2*d0/c or equal to 2*(d0+d0_F)/c; where d1 is the distance from the network device to the terminal in space, d0 is the distance from the network device to a reference point on the earth’s surface, d0_F is the distance from the network device to the base station on the earth’s surface, and c is the speed of light.

[0069] In an embodiment of the invention, in the case where the timing advance is determined autonomously by the terminal, if the communication mode between the terminal and the base station is a regenerative satellite mode so that the satellite can be considered as a base station, the first offset can be calculated from the distance d1 from the satellite to the terminal, and the first offset is 2*d1/c. If the communication mode between the terminal and the base station is satellite transparent transmission mode, then the base station is a base station on the earth's surface, and communication between the terminal and the base station must be carried out through satellite transparent transmission, so that the first offset can be calculated according to with a distance d1 from the satellite to the terminal and a distance d0_F from the satellite to the base station, and the first offset is 2*(d0+d0_F)/c.

[0070] In an embodiment of the invention, in the case where the timing advance is determined non-autonomously by the terminal, the terminal needs to accept the timing advance configured by the satellite or base station. If the communication mode between the terminal and the base station is the regenerative mode of the satellite, so that the satellite can be considered as a base station, the second offset can be calculated according to the distance d0 from the satellite to the reference point on the earth's surface, and the second offset is 2*d0/c . The second offset may be sent to the terminal. If the communication mode between the terminal and the base station is satellite transparent transmission mode, then the base station is a base station on the earth's surface, and the communication between the terminal and the base station must be carried out through satellite transparent transmission, so that the second offset can be calculated from the distance d0 from the satellite to a reference point on the earth's surface and the distance d0_F from the satellite to the base station, with the second offset equal to 2*(d0+d0_F)/c. The second offset may be sent to the terminal.

[0071] In some embodiments of the invention, the first reception timing information includes a third offset of the first contention resolution timer relative to a third reception time and/or a first time duration of the first contention resolution timer; and/or the second reception timing information includes a fourth offset of the second contention resolution timer relative to the fourth reception time and/or a second time duration of the second contention resolution timer.

[0072] The third offset is different from the fourth offset, and/or the first time duration is different from the second time duration.

[0073] In an embodiment of the invention, the first receive timing information and the second receive timing information may comprise two parts, that is, an offset and/or a second contention timer time length.

[0074] In particular, the first reception timing information may include a third offset of the first contention resolution timer for determining a reception time of the contention resolution information relative to the third reception time and/or a first time duration of the first contention resolution timer. The second reception timing information may include a fourth offset of the second contention resolution timer for determining a time to receive the contention resolution information relative to the fourth reception time and/or a second time duration of the second contention resolution timer. The third offset may be different from the fourth offset, and/or the first time duration may be different from the second time duration.

[0075] The first receive timing information may include only the third offset, or only the first duration of the first contention resolution timer, or include both the third offset and the first duration of the first contention resolution timer. The second receive timing information may include only the fourth offset, or only the second duration of the second arbitration timer, or include both the fourth offset and the second duration of the second arbitration timer.

[0076] For example, the first reception timing information includes a third offset and a first duration of a first contention resolution timer, and the second reception timing information includes a fourth offset and a second duration of a second contention resolution timer.

[0077] In the case where the timing advance is determined autonomously by the terminal, since the delay error to be compensated is small, the terminal can relatively accurately determine the moment when feedback information from the base station reaches it, so that a relatively large third offset can be maintained so that start receiving the tie resolution information, and the first time duration of the first tie resolution timer for synchronizing the reception of the tie resolution information may be relatively short to reduce the time consumption of the random access procedure.

[0078] In the case where the timing advance is determined non-autonomously by the terminal, since the delay error to be compensated is large, it is difficult for the terminal to accurately determine the moment when the feedback information from the base station reaches it, so that a relatively large fourth offset can be sustained to begin with receiving the arbitration information, and the second duration of the second arbitration timer for synchronizing the reception of the arbitration information may be relatively large to ensure that the arbitration information can be received from the base station, thereby successfully completing the random access procedure (including a case of successful conflict resolution and a case of unsuccessful conflict resolution).

[0079] FIG. 3 is a flowchart of a random access method according to an embodiment of the present invention. As shown in FIG. 3, receiving feedback information from the base station during the random access procedure in accordance with the first reception timing information includes step S1012.

[0080] In step S1012, the first collision resolution timer is started at a time domain symbol, and the time domain symbol is the first time domain symbol after the third offset from the third reception time.

[0081] Alternatively, receiving feedback information from the base station during the random access procedure in accordance with the second reception timing information includes starting a second collision resolution timer on a time domain symbol, wherein the time domain symbol is a second time domain symbol after fourth offset from the fourth reception time.

[0082] The above symbols may be Orthogonal Frequency Division Multiplexing (OFDM) symbols.

[0083] In an embodiment of the invention, in the case where the timing advance is determined autonomously by the terminal, the terminal may start a first collision resolution timer at the nearest time domain symbol after the third offset from the third reception time to receive collision resolution information transmitted by the base station.

[0084] In an embodiment of the invention, in the case where the timing advance is determined non-autonomously by the terminal, the terminal may start a second collision resolution timer at the nearest time domain symbol after a second offset from the second reception time to receive collision resolution information transmitted by the base station.

[0085] In some embodiments, each of the third receive time and the fourth receive time is a time when the Msg3 message for the random access procedure is transmitted in its entirety.

[0086] In an embodiment of the invention, in the case where the timing advance is determined autonomously by the terminal, the terminal may start the first collision resolution timer on the nearest time domain symbol after the third offset from the completion of transmission of the Msg3 message for the random access procedure to receive the contention resolution information transmitted by the base station.

[0087] In an embodiment of the invention, in the case where the timing advance is determined non-autonomously by the terminal, the terminal may start a second arbitration timer at the nearest time domain symbol after the second offset from the completion of transmission of the Msg3 message for the random access procedure to receive the arbitration information transmitted by the base station.

[0088] In some embodiments, the third offset is greater than the fourth offset and/or the first time duration is less than the second time duration.

[0089] In an embodiment of the invention, the third offset may be greater than the fourth offset, and the first time duration may be less than the second time duration. Therefore, in the case where the timing advance is determined autonomously by the terminal, the terminal may delay receiving the feedback information by a relatively large third offset, and/or the first time duration of the first contention resolution timer may be relatively short to reduce the time spent on the random access procedure. In the case where the timing advance is determined non-autonomously by the terminal, the terminal may delay receiving the feedback information by a relatively small fourth offset, and/or the second duration of the second contention timer may be relatively large to allow the reception of the feedback information from the base station, thereby successfully completing the random access procedure.

[0090] In some embodiments of the invention, the third offset is equal to 2*d1/c or equal to 2*(d1+d0_F)/c, and the fourth offset is equal to 2*d0/c or equal to 2*(d0+d0_F)/c; where d1 is the distance from the network device to the terminal in space, d0 is the distance from the network device to a reference point on the earth’s surface, d0_F is the distance from the network device to the base station on the earth’s surface, ac is the speed of light.

[0091] In an embodiment of the invention, in the case where the timing advance is determined autonomously by the terminal, if the communication mode between the terminal and the base station is a satellite regenerative mode, that is, the satellite can be considered as a base station, the third offset can be calculated according to the distance d1 from the satellite to the terminal, and the third offset is 2*d1/c. If the communication mode between the terminal and the base station is satellite transparent transmission mode, then the base station is located on the earth's surface, and the communication between the terminal and the base station must be carried out through satellite transparent transmission, so that the third offset can be calculated according to the distance d1 from the satellite to the terminal and the distance d0_F from the satellite to the base station, and the third offset is 2*(d0+d0_F)/c.

[0092] In an embodiment of the invention, in case the timing advance is determined non-autonomously by the terminal, the terminal needs to accept the timing advance configured by the satellite or base station. If the communication mode between the terminal and the base station is the regenerative mode of the satellite, that is, the satellite can be considered as a base station, the fourth offset can be calculated according to the distance d0 from the satellite to the reference point on the earth's surface, and the fourth offset is 2*d0/ c. The fourth offset may be transmitted to the terminal. If the communication mode between the terminal and the base station is satellite transparent transmission mode, then the base station is located on the earth's surface, and the communication between the terminal and the base station must be carried out through satellite transparent transmission, so that the fourth offset can be calculated from the distance d0 from satellite to a reference point on the earth's surface and the distance d0_F from the satellite to the base station, with the fourth offset equal to 2*(d0+d0_F)/c. The fourth offset may be transmitted to the terminal.

[0093] FIG. 4 is a flowchart illustrating a random access method according to an embodiment of the present invention. As shown in FIG. 4, the method includes step S102.

[0094] In step S102, indication information transmitted by the base station is received. The indication information includes first reception timing information and/or second reception timing information.

[0095] In an embodiment of the invention, the base station may transmit indication information to the terminal to indicate first reception timing information of the terminal and to indicate second reception timing information of the terminal. The indication information may be further configured to indicate first reception timing information and second reception timing information of the terminal. In the case where the timing advance is determined autonomously by the terminal, the terminal may receive feedback information from the base station during the random access procedure in accordance with the first reception timing information. In the case where the timing advance is determined non-autonomously by the terminal, the terminal may receive feedback information from the base station during the random access procedure in accordance with the second reception timing information.

[0096] It should be noted that step S102 may be performed before the terminal initiates random access.

[0097] FIG. 5 is a flowchart illustrating a configuration indicating method according to an embodiment of the present invention. The method in the embodiments may be applied to a base station in a non-terrestrial network, and the base station may be a base station located on the earth's surface in a non-terrestrial network, or a network device located in space in a non-terrestrial network, such as a satellite, an aerial platform, etc. P. The base station may communicate with the terminal as a user equipment, and the terminal includes, but is not limited to, electronic equipment such as a mobile phone, tablet computer, wearable device, sensor, and Internet of Things device. Below is a description for the case where the network device is a satellite.

[0098] As shown in FIG. 5, the configuration indication method may include the following steps:

[0099] In step S201, indication information containing first reception timing information and second reception timing information is transmitted to the terminal. The indication information is configured to indicate to the terminal that, in response to the timing advance determined offline, feedback information should be received from the base station during the random access procedure in accordance with the first reception timing information, and, in response to the timing advance determined offline, feedback information should be received from the base station during the random access procedure in accordance with the second reception timing information.

[00100] The first reception timing information is different from the second reception timing information.

[00101] According to embodiments of the present invention, the base station may indicate different reception timing information in the case where the timing advance is determined autonomously by the terminal and in the case where the timing advance is determined autonomously by the terminal, so that the terminal can receive feedback information from the base station. stations during the random access procedure based on the first reception timing information in the case that the timing advance is determined autonomously by the terminal, and receive feedback information from the base station during the random access procedure based on the second reception timing information in the case that the timing advance is determined non-autonomously by the terminal. The first reception timing information is different from the second reception timing information.

[00102] That is, the terminal can receive feedback information from the base station based on various reception timing information such as messages Msg2, Msg4, etc., in the case that the timing advance is determined autonomously by the terminal, and in the case that synchronization advance is determined by the terminal non-autonomously.

[00103] For example, the above-mentioned reception timing information includes two pieces of information, that is, an offset and a time window duration. In the case where the timing advance is determined autonomously by the terminal, since the delay error to be compensated for is small, the terminal can relatively accurately determine the moment when the feedback information from the base station reaches it, so that the feedback information can be received after an offset of a relatively large delay. The duration of the time window for receiving feedback information may be relatively short to reduce the time consumption of the random access procedure.

[00104] In the case where the timing advance is determined non-autonomously by the terminal, since the delay error to be compensated is large, it is difficult for the terminal to accurately determine the moment when the feedback information from the base station reaches it, so that the feedback information can be received after the offset from relatively small delay. The duration of the time window for receiving feedback information may be relatively large to ensure that feedback information from the base station can be received, thereby successfully completing the random access procedure.

[00105] In some embodiments of the invention, the first reception timing information comprises a first offset of a first time window for receiving a random access response relative to a first reception time and/or a first duration of the first time window.

[00106] Alternatively, the second reception timing information comprises a second offset of the second time window for receiving the random access response relative to the second reception time and/or a second duration of the second time window.

[00107] The first offset is different from the second offset and/or the first duration is different from the second duration.

[00108] In an embodiment of the invention, the first reception timing information and the second reception timing information may comprise two parts, that is, an offset and/or a time window duration.

[00109] In particular, the first reception timing information may include a first offset of the first time window for receiving the random access response relative to the first reception time and/or a first duration of the first time window. The second reception timing information may include a second offset of the second time window for receiving the random access response relative to the second reception time and/or a second duration of the second time window. The first offset may be different from the second offset, and/or the first duration may be different from the second duration.

[00110] The first reception timing information may include only the first offset, or only the first duration of the first time window, or include both the first offset and the first duration of the first time window. The second reception timing information may include only the second offset, or only the second duration of the second time window, or include both the second offset and the second duration of the second time window.

[00111] For example, the first receive timing information includes a first offset and a first duration of a first time window, and the second receive timing information includes a second offset and a second duration of a second time window.

[00112] In the case where the timing advance is determined autonomously by the terminal, since the delay error to be compensated for is small, the terminal can relatively accurately determine the moment when the feedback information from the base station reaches it, so that the feedback information can be received after the first offsets with a relatively long delay. The first duration of the first time window for receiving feedback information may be relatively short to reduce the time consumption of the random access procedure.

[00113] In the case where the timing advance is determined non-autonomously by the terminal, since the delay error to be compensated is large, it is difficult for the terminal to accurately determine the moment when the feedback information from the base station reaches it, so that the feedback information can be received after the second offset with a relatively short delay, and the second duration of the second time window for receiving feedback information may be relatively long to ensure that feedback information from the base station can be received, thereby successfully completing the random access procedure.

[00114] In some embodiments, each of the first receive time and the second receive time represents a time when the message Msg1 or MsgA for the random access procedure is transmitted in its entirety.

[00115] In one embodiment of the invention, during a 4-step random access procedure, the terminal may receive, in a first time window, random access request response information transmitted by the base station via the nearest downlink physical control channel opportunity, and a first time window represents the time window after the first offset since the completion of message Msg1.

[00116] In one embodiment of the invention, during a 2-step random access procedure, the terminal may receive, in a second time window, random access request response information transmitted by the base station via the nearest downlink physical control channel opportunity, and a second time window represents the time window after the second offset from the completion of transmission of the MsgA message.

[00117] In some embodiments of the invention, the first offset is greater than the second offset and/or the first duration is less than the second duration.

[00118] In an embodiment of the invention, the first offset may be greater than the second offset, and the first duration may be less than the second duration. Therefore, in the case where the timing advance is determined autonomously, the terminal may delay receiving the feedback information by a relatively large first offset, and/or the first duration of the first time window for receiving the feedback information may be relatively short to reduce the time spent in the arbitrary procedure. access. In the case where the timing advance is determined non-autonomously by the terminal, the terminal may delay receiving the feedback information by a relatively small second offset, and/or the second duration of the second time window for receiving the feedback information may be relatively large to ensure that the feedback information from the base station is received, thus successfully completing the random access procedure.

[00119] In some embodiments of the invention, the first offset is equal to 2*d1/c or equal to 2*(d1+d0_F)/c, and the second offset is equal to 2*d0/c or equal to 2*(d0+d0_F)/c; where d1 is the distance from the network device to the terminal in space, d0 is the distance from the network device to a reference point on the earth’s surface, d0_F is the distance from the base station to the terminal, ac is the speed of light.

[00120] In an embodiment of the invention, in the case where the timing advance is determined autonomously, if the communication mode between the terminal and the base station is a satellite regenerative mode, that is, the satellite can be considered as a base station, the first offset can be calculated according to the distance d1 from satellite to the terminal, and the first offset is 2*d1/c. If the communication mode between the terminal and the base station is satellite transparent transmission mode, then the base station is a base station on the earth's surface, and communication between the terminal and the base station must be carried out through satellite transparent transmission, so that the first offset can be calculated according to with a distance d1 from the satellite to the terminal and a distance d0_F from the satellite to the base station, and the first offset is 2*(d0+d0_F)/c.

[00121] In an embodiment of the invention, in the case where the timing advance is determined offline, the terminal needs to accept the timing advance configured by the satellite or base station. If the communication mode between the terminal and the base station is the regenerative mode of the satellite, that is, the satellite can be considered as a base station, the second offset can be calculated according to the distance d0 from the satellite to the reference point on the earth's surface, and the second offset is 2*d0/c . The second offset may be sent to the terminal. If the communication mode between the terminal and the base station is a satellite transparent transmission mode, then the base station is a base station on the earth's surface, and the communication between the terminal and the base station must be carried out through satellite transparent transmission, so that the second offset can be calculated according to with a distance d0 from the satellite to a reference point on the earth’s surface and a distance d0_F from the satellite to the base station, the second offset being equal to 2*(d0+d0_F)/c. The second offset may be sent to the terminal.

[00122] In some embodiments of the invention, the first reception timing information includes a third offset of the first contention resolution timer relative to a third reception time and/or a first time duration of the first contention resolution timer; and/or the second reception timing information includes a fourth offset of the second contention resolution timer relative to the fourth reception time and/or a second time duration of the second contention resolution timer.

[00123] In an embodiment of the invention, the first receive timing information and the second receive timing information may include two parts, that is, an offset and/or a second contention timer time length.

[00124] In particular, the first reception timing information may include a third offset of the first contention resolution timer for determining a reception time of the contention resolution information relative to the third reception time and/or a first time duration of the first contention resolution timer. The second reception timing information may include a fourth offset of the second contention resolution timer for determining a time to receive the contention resolution information relative to the fourth reception time and/or a second time duration of the second contention resolution timer. The third offset may be different from the fourth offset, and/or the first time duration may be different from the second time duration.

[00125] The first reception timing information may include only the third offset, or only the first duration of the first contention resolution timer, or include both the third offset and the first duration of the first contention resolution timer. The second receive timing information may include only the fourth offset, or only the second duration of the second arbitration timer, or include both the fourth offset and the second duration of the second arbitration timer.

[00126] For example, the first reception timing information includes a third offset and a first duration of a first contention resolution timer, and the second reception timing information includes a fourth offset and a second duration of a second contention resolution timer.

[00127] In the case where the timing advance is determined autonomously, since the delay error to be compensated for is small, the terminal can relatively accurately determine the moment when the feedback information from the base station reaches it, so that a relatively large third offset can be maintained so that start receiving the tie resolution information, and the first time duration of the first tie resolution timer for determining the time of receiving the tie resolution information may be relatively short to reduce the time consumption of the random access procedure.

[00128] In the case where the timing advance is determined non-autonomously, because the delay error to be compensated is large, it is difficult for the terminal to accurately determine the moment when the feedback information from the base station reaches it, so a relatively large fourth offset may be maintained to start receiving the information arbitration information, and the second length of the second arbitration timer for synchronizing the reception of the arbitration information may be relatively large to ensure that the arbitration information can be received from the base station, thereby successfully completing the random access procedure (including the case of successful conflict resolution and the case of unsuccessful conflict resolution).

[00129] In some embodiments of the invention, the third offset is greater than the fourth offset and/or the first time duration is less than the second time duration.

[00130] In an embodiment of the invention, the third offset may be greater than the fourth offset, and the first time duration may be less than the second time duration. Therefore, in the case where the timing advance is determined autonomously by the terminal, the terminal may delay receiving the feedback information by a relatively large third offset, and/or the first time duration of the first contention resolution timer may be relatively short to reduce the time spent on the random access procedure. In the case where the timing advance is determined non-autonomously by the terminal, the terminal may delay receiving the feedback information by a relatively small fourth offset, and/or the second duration of the second contention timer may be relatively large to allow the reception of the feedback information from the base station, thereby successfully completing the random access procedure.

[00131] In some embodiments of the invention, the third offset is equal to 2*d1/c or equal to 2*(d1+d0_F)/c, and the fourth offset is equal to 2*d0/c or equal to 2*(d0+d0_F)/c; here d1 is the distance from the network device to the terminal in space, d0 is the distance from the network device to a reference point on the earth’s surface, d0_F is the distance from the network device to the base station on the earth’s surface, and c is the speed of light.

[00132] In an embodiment of the invention, in the case where the timing advance is determined autonomously, if the communication mode between the terminal and the base station is a satellite regenerative mode, that is, the satellite can be considered as a base station, the third offset can be calculated according to the distance d1 from satellite to the terminal, and the third offset is 2*d1/c. If the communication mode between the terminal and the base station is a satellite transparent transmission mode, then the base station is a base station on the earth's surface, and the communication between the terminal and the base station must be carried out through satellite transparent transmission, so that the third offset can be calculated according to with a distance d1 from the satellite to the terminal and a distance d0_F from the satellite to the base station, and the third offset is 2*(d0+d0_F)/c.

[00133] In an embodiment of the invention, in case the timing advance is determined offline, the terminal needs to accept the timing advance configured by the satellite or base station. If the communication mode between the terminal and the base station is the regenerative mode of the satellite, that is, the satellite can be considered as a base station, the fourth offset can be calculated according to the distance d0 from the satellite to the reference point on the earth's surface, and the fourth offset is 2*d0/ c. The fourth offset may be transmitted to the terminal. If the communication mode between the terminal and the base station is satellite transparent transmission mode, then the base station is a base station on the earth's surface, and the communication between the terminal and the base station must be carried out through satellite transparent transmission, so that the fourth offset can be calculated from the distance d0 from the satellite to a reference point on the earth's surface and the distance d0_F from the satellite to the base station, and the fourth offset is 2*(d0+d0_F)/c. The fourth offset may be transmitted to the terminal.
