Description

[Technical field]

[0001] The present disclosure relates to the field of communication technologies, and in particular to a random access method, a configuration instruction method, a random access device, a configuration instruction device, an electronic device, and a computer-readable storage medium. [Background technology]

[0002] As communication technology advances, it becomes necessary to enable communication between base stations and terminals located anywhere on the ground. However, currently, the base stations in the network are located on the ground, and there are many restrictions on the installation of base stations. Therefore, it is difficult to cover the entire ground with terrestrial base stations, so consideration is being given to combining with satellites to provide coverage.

[0003] In a terrestrial network, a base station can transmit a Timing Advance (TA) to a terminal to match an uplink signal frame transmitted by the terminal with a downlink signal frame transmitted from the base station.

[0004] However, when communicating via a non-terrestrial network (NTN) in conjunction with a satellite, since the satellite is in the air and moving at high speed, there is a large delay when the base station communicates with the terminal via the satellite, and since the timing advance is set according to the delay, the timing advance also becomes large, causing several problems. Summary of the Invention

[0005] In response to this, the embodiments of the present disclosure provide a random access method, a configuration instruction method, a random access device, a configuration instruction device, an electronic device, and a computer-readable storage medium to solve the technical problems in the related art.

[0006] A first aspect according to an embodiment of the present disclosure provides a random access method applied to a terminal, the method comprising: receiving feedback information of a base station during random access based on first reception time information in response to the terminal autonomously determining a timing advance; Or, receiving feedback information of a base station during random access based on second reception time information in response to the terminal non-autonomously determining a timing advance; The first reception time information and the second reception time information are different.

[0007] A second aspect of the present disclosure provides a configuration instruction method applied to a base station, the method comprising: A step of transmitting instruction information including first reception time information and second reception time information to a terminal, the instruction information instructing the terminal to receive feedback information of a base station during random access based on the first reception time information when the terminal determines a timing advance autonomously, and to receive feedback information of a base station during random access based on the second reception time information when the terminal determines a timing advance non-autonomously; The first reception time information and the second reception time information are different.

[0008] A third aspect according to an embodiment of the present disclosure provides a random access device applied to a terminal, the device comprising: a feedback receiving module for receiving feedback information of a base station during random access based on first reception time information in response to the terminal autonomously determining a timing advance, and for receiving feedback information of a base station during random access based on second reception time information in response to the terminal non-autonomously determining a timing advance; The first reception time information and the second reception time information are different.

[0009] A fourth aspect according to an embodiment of the present disclosure provides a configuration instruction device applied to a base station, the device comprising: An instruction sending module for sending instruction information including first receiving time information and second receiving time information to a terminal, the instruction information including an instruction sending module for instructing the terminal to receive feedback information of a base station during random access based on the first receiving time information when the terminal determines a timing advance autonomously, and to receive feedback information of a base station during random access based on the second receiving time information when the terminal determines a timing advance non-autonomously; The first reception time information and the second reception time information are different.

[0010] A fifth aspect according to an embodiment of the present disclosure provides an electronic device, A processor; a memory for storing processor-executable instructions; The processor is arranged to implement any of the random access methods described above and / or any of the configuration indication methods described above.

[0011] A sixth aspect according to an embodiment of the present disclosure provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, realizes any of the random access methods described above or any of the placement instruction methods described above.

[0012] According to an embodiment of the present disclosure, the base station indicates different reception time information when the terminal autonomously determines the timing advance and when the terminal non-autonomously determines the timing advance, so that when the terminal autonomously determines the timing advance, the terminal can receive feedback information of the base station during random access based on first reception time information, and when the terminal non-autonomously determines the timing advance, the terminal can receive feedback information of the base station during random access based on second reception time information, where the first reception time information and the second reception time information are different.

[0013] That is, when the terminal determines the timing advance autonomously and when the terminal determines the timing advance non-autonomously, the terminal can receive feedback information from the base station based on different receiving time information in the random access process.

[0014] When the timing advance is determined autonomously, the delay error to be compensated is small, so that the terminal can relatively accurately determine when the feedback information of the base station will arrive, and thus can delay the start of receiving the feedback information by a relatively large offset, and shorten the length of the time window for receiving the feedback information to shorten the time of the random access process.

[0015] When the timing advance is determined non-autonomously, the delay error to be compensated for is large, making it difficult for the terminal to accurately determine when the feedback information from the base station will arrive. As a result, the terminal can start receiving the feedback information by delaying a relatively small offset, lengthening the length of the time window for receiving the feedback information, ensuring that the feedback information from the base station is received, and successfully completing the random access process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, the technical solutions in the embodiments of the present disclosure will be clearly and completely described with reference to the drawings in the embodiments of the present disclosure, but it is clear that the described embodiments are only some embodiments of the present disclosure, and not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present disclosure.

[0018] FIG. 1 is a schematic flowchart of a random access method according to an embodiment of the present disclosure. The method shown in this embodiment can be applied to terminals in a non-terrestrial network, including but not limited to electronic devices such as mobile phones, tablets, wearable devices, sensors, and Internet of Things devices. The terminals can communicate with a base station as a user device, in which case the base station may be a base station on the ground in a non-terrestrial network, or a network device such as a satellite or an airborne platform in a non-terrestrial network. The following mainly describes an example in which the network device is a satellite.

[0019] As shown in FIG. 1, the random access method includes the following steps:

[0020] In step S101, in response to the terminal autonomously determining a timing advance, receiving feedback information of a base station during random access based on first reception time information, and in response to the terminal non-autonomously determining a timing advance, receiving feedback information of a base station during random access based on second reception time information; The first reception time information and the second reception time information are different.

[0021] In addition, the first reception time information and / or the second reception time information in all embodiments of the present disclosure may be placed in the terminal by the base station or may be determined by the terminal itself, and specifically may be set as needed, and the present disclosure does not limit it.

[0022] In non-terrestrial networks, whether communication is between a terminal and a base station located on the ground, or between a base station and a satellite, communication signals need to be transmitted to a satellite. Because satellites are in the air, it takes a long time to transmit communication signals to satellites, and the communication delay between terminals and base stations is large, which can reach a maximum of 541.46 ms.

[0023] In order to compensate for the communication delay in the non-terrestrial network, the terminal can compensate based on the timing advance in the communication process, and the compensation methods here mainly include two:

[0024] The first method is suitable when the terminal can determine its own position by autonomously determining the timing advance, and the terminal can calculate the delay to be compensated based on the distance from the terminal to the satellite, which is suitable for the satellite regeneration mode, i.e., when the satellite is the base station, or calculate the delay to be compensated based on the distance from the terminal to the satellite and the distance or delay from the satellite to the base station, which is applicable when the base station is on the ground.

[0025] The delay that needs to be compensated determined by the terminal may be a timing advance that may be reported to the base station during random access, such as being carried in Msg 3 or MsgA during random access. When the terminal communicates with the base station, it may compensate for all the timing advance, or may perform partial compensation, such as receiving a common timing advance (which may be referred to as common TA) broadcast by the network and then compensating for the difference between all the timing advances and the common timing advance.

[0026] The second method is suitable for the case where the terminal determines the timing advance non-autonomously and the terminal cannot determine its own position. The terminal can receive a common timing advance broadcast by the network, and then when communicating with the base station, it compensates for this common timing advance, or the terminal does not compensate for the timing advance, but the network compensates for the common timing advance. For example, the satellite compensates for the common timing advance.

[0027] For example, let d0 be the distance from the satellite to a terrestrial reference point (where the satellite can point to its projected position on the ground), d1 be the distance between the satellite and the terminal, d0_F be the distance from the satellite to the base station, and c be the speed of light. Therefore, in satellite playback mode, the common timing advance is equal to the two-way delay from the satellite to the terrestrial reference point, specifically 2*d0 / c, and when the terminal communicates with a terrestrial base station, the common timing advance is the sum of the two-way delay from the satellite to the terrestrial reference point and the two-way delay from the satellite to the terrestrial base station, specifically 2*(d0+d0_F) / c.

[0028] It can be seen that the delays that the terminal compensates for based on the above two methods are different.

[0029] When the timing advance is determined autonomously, the terminal position can be determined, so the timing advance determined based on this is relatively accurate, and the compensation delay is also relatively accurate; generally, it is guaranteed that the error between the actual delay and the compensation delay is within 1 ms.

[0030] On the other hand, when the timing advance is determined non-autonomously, rather than determining the timing advance based on the terminal's position, compensation is performed based on a common timing advance, and the common timing advance does not include the distance d1 from the satellite to the terminal, but only the distance d0 from the satellite to the ground reference point. Therefore, the delay error between the actual delay and the compensation is large, and this error is positively correlated with the difference between d1 and d0. In a cell with a coverage radius of 3,500 km, this error can even reach 20.6 ms.

[0031] In order for a terminal to compensate for delay during random access, it needs to compensate using the above-mentioned autonomous timing advance determination method or non-autonomous advance determination method. That is, when transmitting information (e.g., Msg1, Msg3, MsgA, etc.) to a base station during random access, it is necessary to advance all timing advances or advance the difference between all timing advances and the common timing advance using the autonomous timing advance determination method, or advance the common timing advance using the autonomous timing advance determination method or compensate the common timing advance by the network.

[0032] In addition, in order for the terminal to receive feedback information from the base station during random access, it is necessary to receive it based on the above delay. For example, in response to a random access response transmitted from the base station, the terminal can receive it after transmitting Msg1, but due to the existence of the above delay, the feedback information is transmitted to the terminal after the terminal transmits Msg1 and then the above delay, so the terminal needs to wait at least the above delay after transmitting Msg1 before receiving the feedback information transmitted from the base station.

[0033] From the above, the delay to be compensated for differs between when the terminal determines the timing advance autonomously and when the terminal determines the timing advance non-autonomously. When the terminal determines the timing advance autonomously, the delay to be compensated for is determined based on the distance d1 between the terminal and the satellite, and when the terminal determines the timing advance non-autonomously, the delay to be compensated for is instructed to the terminal by the satellite or base station, and specifically, is determined based on the distance d0 from the satellite to a reference point on the ground.

[0034] Generally, d1 and d0 are not equal, and d1 is the real distance between the terminal and the satellite, so determining the delay to be corrected based on d1 is relatively accurate, and determining the delay to be corrected based on d0 has a large error. When receiving the feedback information based only on the reception time information, in order to accommodate the above two compensation methods, it is necessary to satisfy the case where the delay error is large and the case where the delay error is relatively accurate, so if d0 is adopted as the delay to be compensated to determine reception of the feedback information, the terminal needs a long time to receive the feedback information, and the reception time is also relatively long in order to be able to receive the feedback information even when the delay error is large.

[0035] According to an embodiment of the present disclosure, the base station indicates different reception time information when the terminal autonomously determines the timing advance and when the terminal non-autonomously determines the timing advance, so that when the terminal autonomously determines the timing advance, the terminal can receive feedback information of the base station during random access based on first reception time information, and when the terminal non-autonomously determines the timing advance, the terminal can receive feedback information of the base station during random access based on second reception time information, where the first reception time information and the second reception time information are different.

[0036] That is, when the terminal determines the timing advance autonomously and when the terminal determines the timing advance non-autonomously, in the random access process, it can receive feedback information from the base station, for example, Msg2, Msg4, etc., based on different reception time information.

[0037] For example, the above-mentioned reception timing information includes two pieces of information: offset and time window length. When autonomously determining timing advance, the delay error to be compensated is small, so that the terminal can relatively accurately determine when the feedback information from the base station arrives, and thus can delay a relatively large offset to start receiving the feedback information, shorten the length of the time window for receiving the feedback information, and shorten the time of the random access process.

[0038] When the timing advance is determined non-autonomously, the delay error to be compensated for is large, making it difficult for the terminal to accurately determine when the feedback information from the base station will arrive. As a result, the terminal can start receiving the feedback information by delaying a relatively small offset, lengthening the length of the time window for receiving the feedback information, ensuring that the feedback information from the base station is received, and successfully completing the random access process.

[0039] Optionally, the first reception time information comprises a first offset of a first time window relative to a first reception time for receiving a random access response and / or a first length of the first time window; and / or the second reception time information includes a second offset of a second time window relative to a second reception time for receiving a random access response and / or a second length of the second time window; The first offset and the second offset are different, and / or the first length and the second length are different.

[0040] In one embodiment, the first reception time information and the second reception time information may include two parts: an offset and / or a length of a time window.

[0041] Specifically, the first reception time information includes a first offset of a first time window relative to a first reception time at which the random access response is received and / or a first length of the first time window, and the second reception time information includes a second offset of a second time window relative to a second reception time at which the random access response is received and / or a second length of the second time window, and the first offset and the second offset are different, and / or the first length and the second length are different.

[0042] The first reception time information includes only the first offset, or includes only the first length of the first time window, or includes the first offset and the first length of the first time window, and the second reception time information includes only the second offset, or includes only the second length of the second time window, or includes the second offset and the second length of the second time window.

[0043] For example, the first reception time information includes a first offset and a first length of a first time window, and the second reception time information includes a second offset and a second length of a second time window.

[0044] When the timing advance is determined autonomously, the delay error to be compensated is small, so that the terminal can relatively accurately determine when the feedback information of the base station arrives, thereby delaying the start of receiving the feedback information by a relatively large first offset, and shortening the first length of the time window for receiving the first feedback information to shorten the time of the random access process.

[0045] When the timing advance is determined non-autonomously, the delay error to be compensated is large, so that it is difficult for the terminal to accurately determine when the feedback information from the base station will arrive. Therefore, the terminal can start receiving the feedback information by delaying a relatively small second offset, and the length of the second time window for receiving the feedback information can be increased, so that the feedback information from the base station can be received and the random access process can be completed smoothly.

[0046] 2 is a schematic flowchart of another random access method according to an embodiment of the present disclosure. As shown in FIG. 2, the step of receiving feedback information of a base station during random access according to the first receiving time information includes: In a physical downlink control channel time (PDCCH occasion) in which the first reception time is the closest to the first offset, the first time window is continued to receive random access response information transmitted from a base station. and / or receiving feedback information of the base station during random access based on the second reception time information, The method includes a step S1011 including a step of continuing the second time window at the physical downlink control channel time at which the second reception time is closest after waiting for the second offset, to receive random access response information transmitted from a base station.

[0047] In one embodiment, when the terminal autonomously determines the timing advance, the terminal may wait for a first offset from a first reception time and then continue the first time window during the nearest physical downlink control channel timing to receive random access response information transmitted by the base station.

[0048] In one embodiment, when the terminal determines the timing advance non-autonomously, it may wait for a second offset from the second reception time and then continue the second time window during the nearest physical downlink control channel timing to receive the random access response information transmitted by the base station.

[0049] Optionally, the first receiving time and the second receiving time are times when the transmission of random access Msg1 or MsgA is completed.

[0050] In one embodiment, during a four-step random access, the terminal may continue the first time window to receive random access response information transmitted by the base station at the closest physical downlink control channel timing after waiting for a first offset from the time when transmission of Msg1 is completed.

[0051] In one embodiment, during two-step random access, the terminal may continue the second time window to receive random access response information transmitted from the base station at the closest physical downlink control channel timing after waiting for the second offset from the time when transmission of MsgA is completed.

[0052] Optionally, the first offset is greater than the second offset and / or the first length is less than the second length.

[0053] In one embodiment, the first offset may be greater than the second offset, and the first length may be less than the second length. Thus, when the terminal autonomously determines the timing advance, the terminal may delay the reception of feedback information by a relatively large first offset and / or shorten the first length of the first time window for receiving feedback information, which facilitates shortening the time of the random access process. When the terminal non-autonomously determines the timing advance, the terminal may delay the reception of feedback information by a relatively small second offset and / or lengthen the second length of the second time window for receiving feedback information, so as to be able to receive feedback information from the base station, which can ensure the reception of feedback information from the base station, and the random access process can be completed smoothly.

[0054] Alternatively, the first offset is equal to 2*d1 / c, or equal to 2*(d1+d0_F) / c; the second offset is equal to 2*d0 / c, or equal to 2*(d0+d0_F) / c; d1 is the distance from a network device in the air to the terminal, d0 is the distance from the network device to a reference point on the ground, d0_F is the distance from the network device to a base station on the ground, and c is the speed of light.

[0055] In one embodiment, when the timing advance is determined autonomously, the communication method between the terminal and the base station is a satellite regeneration method, and the satellite can be understood as a base station, so the first offset can be calculated from the distance d1 from the satellite to the terminal, and the first offset is equal to 2*d1 / c; when the communication method between the terminal and the base station is a satellite penetration method, and the base station is a terrestrial base station, and satellite penetration is required for communication between the terminal and the base station, the first offset can be calculated from the distance d1 from the satellite to the terminal and the distance d0_F from the satellite to the base station, and the first offset is equal to 2*(d0+d0_F) / c.

[0056] In one embodiment, when determining the timing advance non-autonomously, the terminal needs to receive a timing advance arranged by a satellite or a base station, and when the communication method between the terminal and the base station is a satellite regeneration method, the satellite can be understood as a base station, so the second offset can be calculated from the distance d0 from the satellite to a ground reference point, the second offset is equal to 2*d0 / c, and the second offset can be further transmitted to the terminal; when the communication method between the terminal and the base station is a satellite transmission method, the base station is a terrestrial base station, and satellite transmission is required for the communication between the terminal and the base station, the second offset can be calculated from the distance d0 from the satellite to the ground reference point and the distance d0_F from the satellite to the base station, the second offset is equal to 2*(d0+d0_F) / c, and the second offset can be further transmitted to the terminal.

[0057] Optionally, the first reception time information includes a third offset of a first contention resolution timer relative to a third reception time, and / or a first timing length of the first contention resolution timer; and / or the second reception time information includes a fourth offset of a second contention resolution timer relative to a fourth reception time and / or a second timing length of the second contention resolution timer; The third offset and the fourth offset are different, and / or the duration of the first timing and the duration of the second timing are different.

[0058] In one embodiment, the first receiving time information and the second receiving time information may include two portions of an offset and / or a time length of the second timing of the contention resolution timer.

[0059] Specifically, the first receiving time information may include a third offset of the first contention resolution timer relative to a third receiving time for timing the receiving contention resolution information and / or a first timing duration of the first contention resolution timer, and the second receiving time information may include a fourth offset of the second contention resolution timer relative to a fourth receiving time for timing the receiving contention resolution information and / or a second timing duration of the second contention resolution timer. Also, the third offset and the fourth offset may be different, and / or the first timing duration and the second timing duration may be different.

[0060] The first receiving time information may include only the third offset, or may include only the duration of the first timing of the first contention resolution timer, or may include the third offset and the duration of the first timing of the first contention resolution timer, and the second receiving time information may include only the fourth offset, or may include only the second timing of the second contention resolution timer, or may include the fourth offset and the duration of the second timing of the second contention resolution timer.

[0061] For example, the first receiving time information includes a third offset and a time length of a first timing of a first contention resolution timer, and the second receiving time information includes a fourth offset and a time length of a second timing of a second contention resolution timer.

[0062] When the timing advance is determined autonomously, the delay error to be compensated is small, so that the terminal can relatively accurately determine when the feedback information from the base station arrives, thereby delaying the start of receiving the contention resolution information by a relatively large third offset, and shortening the time length of the first timing of the first contention resolution timer that times the received contention resolution information, thereby facilitating the shortening of the time of the random access process.

[0063] When the timing advance is determined non-autonomously, due to a large delay error to be compensated for, it is difficult for the terminal to accurately determine when the feedback information from the base station arrives, so that the terminal can start receiving the contention resolution information by delaying a relatively small fourth offset, and the time length of the second timing of the second contention resolution timer that times the contention resolution information can be extended, so as to ensure that the contention resolution information from the base station is received, and the random access process can be completed smoothly (including both successful contention resolution and unsuccessful contention resolution).

[0064] 3 is a schematic flowchart of yet another random access method according to an embodiment of the present disclosure. As shown in FIG. 3, the step of receiving feedback information of a base station during random access according to the first receiving time information includes: starting the first contention resolution timer in a time domain symbol in which the third reception time is closest to the third offset; and / or receiving feedback information of the base station during random access based on the second reception time information, Step S1012 includes starting the second contention resolution timer in a time domain symbol in which the fourth reception time is closest to the fourth offset.

[0065] The symbols may be orthogonal frequency division multiplexing OFDM symbols.

[0066] In one embodiment, when the terminal autonomously determines the timing advance, the terminal can turn on the first contention resolution timer from the third reception time to the closest time domain symbol after waiting for the third offset, and receive contention resolution information transmitted from the base station.

[0067] In one embodiment, when the terminal timing advance is determined non-autonomously, a second contention resolution timer can be turned on from the second reception time to the closest time domain symbol after waiting for the second offset, and contention resolution information transmitted from the base station can be received.

[0068] Optionally, the third receiving time and the fourth receiving time are times when the transmission of the random access Msg3 is completed.

[0069] In one embodiment, when the terminal autonomously determines the timing advance, it can turn on the first contention resolution timer from the third reception time at which the transmission of the random access Msg3 is completed to the closest time domain symbol after waiting for a third offset, and receive the contention resolution information transmitted from the base station.

[0070] In one embodiment, when the terminal determines the timing advance non-autonomously, it can turn on a second contention resolution timer to the closest time domain symbol from the reception time when the transmission of the random access Msg3 is completed, and then receive the contention resolution information transmitted from the base station after waiting for a second offset.

[0071] Optionally, the third offset is greater than the fourth offset and / or the first timing duration is less than the second timing duration.

[0072] In one embodiment, the third offset may be greater than the fourth offset, and the first timing length may be less than the second timing length. Thus, when the terminal determines the timing advance autonomously, it may delay the reception of feedback information by a relatively large third offset and / or shorten the first timing length of the first contention resolution timer to facilitate shortening the time of the random access process. When the terminal determines the timing advance non-autonomously, it may delay the reception of feedback information by a relatively small fourth offset and / or extend the second timing length of the second contention resolution timer to ensure that the feedback information from the base station is received and the random access process can be completed smoothly.

[0073] Alternatively, the third offset is equal to 2*d1 / c, or equal to 2*(d1+d0_F) / c; the fourth offset is equal to 2*d0 / c, or equal to 2*(d0+d0_F) / c; d1 is the distance from a network device in the air to the terminal, d0 is the distance from the network device to a reference point on the ground, d0_F is the distance from the network device to a base station on the ground, and c is the speed of light.

[0074] In one embodiment, when the timing advance is determined autonomously, if the communication method between the terminal and the base station is a satellite regeneration method, the satellite can be understood as the base station, so the third offset can be calculated from the distance d1 from the satellite to the terminal, and the third offset is equal to 2*d1 / c; if the communication method between the terminal and the base station is a satellite transmission method, the base station is a terrestrial base station, and satellite transmission is required for communication between the terminal and the base station, the third offset can be calculated from 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 equal to 2*(d0+d0_F) / c.

[0075] In one embodiment, when the timing advance is determined non-autonomously, the terminal needs to receive a timing advance that is configured by a satellite or a base station, and when the communication method between the terminal and the base station is a satellite regeneration method, the satellite can be understood as the base station, so the third offset can be calculated from the distance d1 from the satellite to the terminal, and the third offset is equal to 2*d1 / c; when the communication method between the terminal and the base station is a satellite transmission method, the base station is a terrestrial base station, and satellite transmission is required for the communication between the terminal and the base station, the third offset can be calculated from 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 equal to 2*(d0+d0_F) / c.

[0076] 4 is a schematic flowchart of yet another random access method according to an embodiment of the present disclosure. As shown in FIG. 4, the method includes: The method includes a step S102 of receiving instruction information transmitted from the base station, the instruction information including the first receiving time information and / or the second receiving time information.

[0077] In one embodiment, the base station can send instruction information to the terminal, thereby instructing the terminal of the above-mentioned first receiving time information, and may also instruct the terminal of the above-mentioned second receiving time information, where the instruction information is further used to indicate the roles of the first receiving time information and the second receiving time information of the terminal, specifically, when the terminal autonomously determines a timing advance, it receives feedback information of the base station during random access based on the first receiving time information, and when the terminal non-autonomously determines a timing advance, it receives feedback information of the base station during random access based on the second receiving time information.

[0078] It should be noted that step S102 can be executed before the terminal starts random access.

[0079] FIG. 5 is a schematic flowchart of a configuration instruction method according to an embodiment of the present disclosure. The method shown in this embodiment can be applied to a base station in a non-terrestrial network, which may be a base station on the ground in the non-terrestrial network, or a network device in the air in the non-terrestrial network, such as a satellite or an airborne platform. The base station can communicate with a terminal, which is a user device, including but not limited to electronic devices such as a mobile phone, a tablet, a wearable device, a sensor, an Internet of Things device, etc. The following mainly provides an exemplary description of the case where the network device is a satellite.

[0080] As shown in FIG. 5, the arrangement instruction method includes: A step S201 of sending instruction information to a terminal, the instruction information including first reception time information and second reception time information, instructing the terminal to receive feedback information of a base station during random access based on the first reception time information when the terminal determines a timing advance autonomously, and to receive feedback information of a base station during random access based on the second reception time information when the terminal determines a timing advance non-autonomously; The first reception time information and the second reception time information are different.

[0081] According to an embodiment of the present disclosure, the base station indicates different reception time information when the terminal autonomously determines the timing advance and when the terminal non-autonomously determines the timing advance, so that when the terminal autonomously determines the timing advance, the terminal can receive feedback information of the base station during random access based on first reception time information, and when the terminal non-autonomously determines the timing advance, the terminal can receive feedback information of the base station during random access based on second reception time information, where the first reception time information and the second reception time information are different.

[0082] That is, when the terminal determines the timing advance autonomously and when the terminal determines the timing advance non-autonomously, in the random access process, it can receive feedback information from the base station, for example, Msg2, Msg4, etc., based on different reception time information.

[0083] For example, the above-mentioned receiving timing information includes two pieces of information: offset and time window length. When autonomously determining timing advance, the delay error to be compensated is small, so that the terminal can relatively accurately determine when the feedback information from the base station arrives, and thus delays a relatively large offset to start receiving the feedback information, and shortens the length of the time window for receiving the feedback information, which facilitates shortening the time of the random access process.

[0084] When the timing advance is determined non-autonomously, the delay error to be compensated for is large, making it difficult for the terminal to accurately determine when the feedback information from the base station will arrive. As a result, the terminal can start receiving the feedback information by delaying a relatively small offset, lengthening the length of the time window for receiving the feedback information, ensuring that the feedback information from the base station is received, and successfully completing the random access process.

[0085] Optionally, the first reception time information comprises a first offset of a first time window relative to a first reception time for receiving a random access response and / or a first length of the first time window; and / or the second reception time information includes a second offset of a second time window relative to a second reception time for receiving a random access response and / or a second length of the second time window; The first offset and the second offset are different, and / or the first length and the second length are different.

[0086] In one embodiment, the first reception time information and the second reception time information may include two parts: an offset and / or a length of a time window.

[0087] Specifically, the first reception time information includes a first offset of a first time window relative to a first reception time at which the random access response is received and / or a first length of the first time window, and the second reception time information includes a second offset of a second time window relative to a second reception time at which the random access response is received and / or a second length of the second time window, and the first offset and the second offset are different, and / or the first length and the second length are different.

[0088] The first reception time information includes only the first offset, or includes only the first length of the first time window, or includes the first offset and the first length of the first time window, and the second reception time information includes only the second offset, or includes only the second length of the second time window, or includes the second offset and the second length of the second time window.

[0089] For example, the first reception time information includes a first offset and a first length of a first time window, and the second reception time information includes a second offset and a second length of a second time window.

[0090] When the timing advance is determined autonomously, the delay error to be compensated is small, so that the terminal can relatively accurately determine when the feedback information of the base station arrives, thereby delaying the start of receiving the feedback information by a relatively large first offset, and shortening the first length of the time window for receiving the first feedback information to shorten the time of the random access process.

[0091] When the timing advance is determined non-autonomously, the delay error to be compensated is large, so that it is difficult for the terminal to accurately determine when the feedback information from the base station will arrive. Therefore, the terminal can start receiving the feedback information by delaying a relatively small second offset, and the length of the second time window for receiving the feedback information can be increased, so that the feedback information from the base station can be received and the random access process can be completed smoothly.

[0092] Optionally, the first receiving time and the second receiving time are times when the transmission of random access Msg1 or MsgA is completed.

[0093] In one embodiment, during four-step random access, the terminal continues the first time window to receive random access response information transmitted by the base station at the closest physical downlink control channel timing after waiting for the first offset from the time when transmission of Msg1 is completed.

[0094] In one embodiment, during two-step random access, the terminal continues the second time window to receive random access response information transmitted from the base station at the physical downlink control channel time closest to the reception time at which transmission of MsgA is completed after waiting for the second offset.

[0095] Optionally, the first offset is greater than the second offset and / or the first length is less than the second length.

[0096] In one embodiment, the first offset may be greater than the second offset, and the first length may be less than the second length. Thus, when the terminal autonomously determines the timing advance, the terminal may delay the reception of feedback information by a relatively large first offset and / or shorten the first length of the first time window for receiving feedback information, which facilitates shortening the time of the random access process. When the terminal non-autonomously determines the timing advance, the terminal may delay the reception of feedback information by a relatively small second offset and / or lengthen the second length of the second time window for receiving feedback information, so as to be able to receive feedback information from the base station, which can ensure the reception of feedback information from the base station, and the random access process can be completed smoothly.

[0097] Alternatively, the first offset is equal to 2*d1 / c, or equal to 2*(d1+d0_F) / c; the second offset is equal to 2*d0 / c, or equal to 2*(d0+d0_F) / c; d1 is the distance from a network device in the air to the terminal, d0 is the distance from the network device to a reference point on the ground, d0_F is the distance from the base station to the terminal, and c is the speed of light.

[0098] In one embodiment, when the timing advance is determined autonomously, if the communication method between the terminal and the base station is a satellite regeneration method, the satellite can be understood as the base station, so the first offset can be calculated from the distance d1 from the satellite to the terminal, and the first offset is equal to 2*d1 / c; if the communication method between the terminal and the base station is a satellite transmission method, the base station is a terrestrial base station, and satellite transmission is required for communication between the terminal and the base station, the first offset can be calculated from the distance d1 from the satellite to the terminal and the distance d0_F from the satellite to the base station, and the first offset is equal to 2*(d0+d0_F) / c.

[0099] In one embodiment, when the timing advance is determined non-autonomously, the terminal needs to receive a timing advance that is configured by a satellite or a base station, and when the communication method between the terminal and the base station is a satellite regeneration method, the satellite can be understood as a base station, so the second offset can be calculated from the distance d0 from the satellite to the terminal, the second offset is equal to 2*d0 / c, and the second offset can be transmitted to the terminal; when the communication method between the terminal and the base station is a satellite transmission method, the base station is a terrestrial base station, and satellite transmission is required for the communication between the terminal and the base station, the second offset can be calculated from the distance d0 from the satellite to the terrestrial reference point and the distance d0_F from the satellite to the base station, the second offset is equal to 2*(d0+d0_F) / c, and the second offset can be transmitted to the terminal.

[0100] Optionally, the first reception time information includes a third offset of a first contention resolution timer relative to a third reception time, and / or a first timing length of the first contention resolution timer; and / or The second receive time information includes a fourth offset of a second contention resolution timer relative to a fourth receive time and / or a second timing length of the second contention resolution timer.

[0101] In one embodiment, the first receiving time information and the second receiving time information may include two portions of an offset and / or a time length of the second timing of the contention resolution timer.

[0102] Specifically, the first receiving time information may include a third offset of the first contention resolution timer relative to a third receiving time for timing the receiving contention resolution information and / or a first timing duration of the first contention resolution timer, and the second receiving time information may include a fourth offset of the second contention resolution timer relative to a fourth receiving time for timing the receiving contention resolution information and / or a second timing duration of the second contention resolution timer. Also, the third offset and the fourth offset may be different, and / or the first timing duration and the second timing duration may be different.

[0103] The first receiving time information may include only the third offset, or may include only the duration of the first timing of the first contention resolution timer, or may include the third offset and the duration of the first timing of the first contention resolution timer, and the second receiving time information may include only the fourth offset, or may include only the second timing of the second contention resolution timer, or may include the fourth offset and the duration of the second timing of the second contention resolution timer.

[0104] For example, the first receiving time information includes a third offset and a time length of a first timing of a first contention resolution timer, and the second receiving time information includes a fourth offset and a time length of a second timing of a second contention resolution timer.

[0105] When the timing advance is determined autonomously, the delay error to be compensated is small, so that the terminal can relatively accurately determine when the feedback information from the base station arrives, thereby delaying the start of receiving the contention resolution information by a relatively large third offset, and shortening the time length of the first timing of the first contention resolution timer that times the received contention resolution information, thereby facilitating the shortening of the time of the random access process.

[0106] When the timing advance is determined non-autonomously, due to a large delay error to be compensated for, it is difficult for the terminal to accurately determine when the feedback information from the base station arrives, so that the terminal can start receiving the contention resolution information by delaying a relatively small fourth offset, and the time length of the second timing of the second contention resolution timer that times the contention resolution information can be extended, so as to ensure that the contention resolution information from the base station is received, and the random access process can be completed smoothly (including both successful contention resolution and unsuccessful contention resolution).

[0107] Optionally, the third offset is greater than the fourth offset and / or the first timing duration is less than the second timing duration.

[0108] In one embodiment, the third offset may be greater than the fourth offset, and the first timing length may be less than the second timing length. Thus, when the terminal determines the timing advance autonomously, it may delay the reception of feedback information by a relatively large third offset and / or shorten the first timing length of the first contention resolution timer to facilitate the shortening of the first timing length of the first contention resolution timer. When the terminal determines the timing advance non-autonomously, it may delay the reception of feedback information by a relatively small fourth offset and / or extend the second timing length of the second contention resolution timer to ensure the reception of feedback information from the base station and the smooth completion of the random access process.

[0109] Alternatively, the third offset is equal to 2*d1 / c, or equal to 2*(d1+d0_F) / c; the fourth offset is equal to 2*d0 / c, or equal to 2*(d0+d0_F) / c; d1 is the distance from a network device in the air to the terminal, d0 is the distance from the network device to a reference point on the ground, d0_F is the distance from the network device to a base station on the ground, and c is the speed of light.

[0110] In one embodiment, when the timing advance is determined autonomously, if the communication method between the terminal and the base station is a satellite regeneration method, the satellite can be understood as the base station, so the third offset can be calculated from the distance d1 from the satellite to the terminal, and the third offset is equal to 2*d1 / c; if the communication method between the terminal and the base station is a satellite transmission method, the base station is a terrestrial base station, and satellite transmission is required for communication between the terminal and the base station, the third offset can be calculated from 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 equal to 2*(d0+d0_F) / c.

[0111] In one embodiment, when the timing advance is determined non-autonomously, the terminal needs to receive a timing advance that is configured by a satellite or a base station, and when the communication method between the terminal and the base station is a satellite regeneration method, the satellite can be understood as the base station, so the fourth offset can be calculated from the distance d0 from the satellite to the ground reference point, the fourth offset is equal to 2*d0 / c, and the fourth offset can be transmitted to the terminal; when the communication method between the terminal and the base station is a satellite transmission method, the base station is a terrestrial base station, and satellite transmission is required for the communication between the terminal and the base station, the fourth offset can be calculated from the distance d0 from the satellite to the ground reference point and the distance d0_F from the satellite to the base station, the fourth offset is equal to 2*(d0+d0_F) / c, and the fourth offset can be transmitted to the terminal.
