Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular, to a method, an apparatus, and a readable storage medium for receiving and sending configuration information. Background Art

[0002] To achieve global communication coverage for 5th generation (5G) communication networks, the 3rd generation partnership project (3GPP) organization is studying the adaptation of the new radio (NR) protocol to non-terrestrial networks (NTN). NTN communication includes satellite communication, air to ground (ATG) communication, etc. Compared with terrestrial communication, NTN communication has different channel characteristics, such as large transmission delay, large Doppler frequency offset, etc. For example, the round-trip delay of geostationary earth orbit (GEO) satellite communication (regenerative mode) is 238 - 270 ms. The round-trip delay of low earth orbit (LEO) satellite communication (orbital altitude of 1200 km, regenerative mode) is 8 ms - 20 ms.

[0003] For terrestrial network (TN) devices of 5G NR technology, the round-trip delay within a communication cell is absorbed by the cyclic prefix (CP) of the physical random access channel (PRACH). However, for non-terrestrial networks (NTN), the round-trip delay is relatively large, and it is unable to timely track the propagation delay jitter in the NTN network, and is not suitable for using the above-mentioned method of absorbing with a cyclic prefix.

[0004] In addition, during the communication process in non-terrestrial networks, some user equipment (UE) cannot simultaneously balance the positioning process of the global navigation satellite system (GNSS) and the transmission of service data. Summary of the Invention

[0075] The embodiments of the present disclosure will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0076] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the embodiments of the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0077] The method for transmitting configuration information provided by the embodiments of the present disclosure can be applied to a non-terrestrial network (NTN) system 100. Figure 1 A possible architecture of a non-terrestrial network system applicable to the embodiments of the present application is shown. The system 100 may be composed of a terminal device 101 (or called a user terminal, user equipment), a first network device 102, and a second network device 103. Among them, the communication link between the first network device 102 and the second network device 103 is a feedback link; the communication link between the second network device 103 and the terminal device 101 is a service link.

[0078] The terminal device 101 can be a wireless terminal device capable of receiving scheduling and indication information from a network device. Such as a device for providing voice and / or data connectivity to a user, or a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. The wireless terminal device can communicate with one or more core networks or the Internet via a radio access network (such as a radio access network, RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or called a "cellular" phone, mobile phone), a computer, and a communication chip. For example, it can be a portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted mobile device that can exchange voice and / or data with the radio access network. The terminal can specifically be a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a tablet (Pad), a computer with wireless transceiver capabilities, and other devices. The terminal can also include a subscriber unit, a subscriber station, a mobile station, a mobile station (MS), a remote station, an access point (AP), a remote terminal device, an access terminal device, a user terminal device, a user agent, a user station (SS), a customer premises equipment (CPE), a terminal, a mobile terminal (MT), etc. The wireless terminal device can also be a wearable device and a next-generation communication system. For example, a terminal device in a 5G network or a terminal device in a future evolved public land mobile network (PLMN) network, a terminal device in an NR communication system, etc.

[0079] The first network device 102 can be a gateway station (or called a ground station, an earth station, a gateway) that can be used to connect the second network device 103 to the core network.

[0080] The second network device 103 may be a satellite (or satellite base station), a geostationary earth orbit (GEO) satellite, a medium earth orbit (MEO) satellite or a low earth orbit (LEO) satellite of a non-geostationary earth orbit (NGEO), a high altitude platform station (HAPS), etc., which is not limited here.

[0081] During the communication process of the NTN system, some terminal devices 101 with relatively low communication capabilities cannot perform GNSS positioning and data transmission simultaneously. Therefore, for such terminal devices 101, the first network device 102 needs to determine corresponding configuration information so that the terminal device 101 can perform GNSS positioning and data transmission at appropriate times.

[0082] In the present disclosure, according to the GNSS positioning capabilities reported by the terminal device 101 in NTN communication, the first network device 102 can determine the configuration information according to the GNSS positioning capabilities of the user equipment, thereby indicating the timing for the terminal device 101 to receive and process GNSS signals to obtain or re-obtain GNSS positioning information, so that such terminal devices 101 can perform effective service data transmission while maintaining effective uplink synchronization.

[0083] The embodiments of the present disclosure provide a method for receiving configuration information. Refer to Figure 2 , Figure 2 is a flowchart of a method for transmitting configuration information shown according to an exemplary embodiment. As Figure 2 shown, this method includes:

[0084] Step S21: The terminal device 101 determines the first information and the second information; wherein, the first information corresponds to the duration required for receiving the Global Navigation Satellite System (GNSS) signals and obtaining GNSS positioning information according to the GNSS signals, and the second information corresponds to the effective duration of the GNSS positioning information obtained by the terminal device.

[0085] Step S22: The terminal device 101 sends the first information and the second information to the non-terrestrial network (NTN) device.

[0086] Step S23: The network device receives the first information and the second information from the terminal device 101.

[0087] Step S24: The network device determines configuration information according to the first information and the second information, where the configuration information is used to instruct the terminal device to determine the timing for receiving and processing GNSS signals to obtain or re-obtain GNSS positioning information.

[0088] Step S25: The network device sends the configuration information to the terminal device 101.

[0089] Step S26: The terminal device 101 receives the configuration information from the network device, where the configuration information is determined by the NTN device according to the first information and the second information, and the configuration information is used to instruct the terminal device 101 to determine the timing for receiving and processing GNSS signals to obtain or re-obtain GNSS positioning information.

[0090] In some possible implementation manners, the network device is the first network device 102 in the non-terrestrial network NTN.

[0091] In some possible implementation manners, in step S21, the first information and the second information may characterize the GNSS positioning capability of the terminal device 101.

[0092] The first information may reflect the duration required for the terminal device 101 to receive GNSS signals and locate the position of the terminal device. Among them, the process of receiving GNSS signals in the first information includes the process of searching for satellites. For example, when positioning requires using the signals of 3 satellites for positioning, the process of searching for satellites includes the process of searching for the signals of 3 satellites. Obtaining GNSS positioning information according to the GNSS signals in the first information includes calculating the position information of the terminal device according to the GNSS signals.

[0093] The second information may reflect the effective duration of the positioning information, and the positioning information may be the position information of the terminal device located according to the GNSS signals involved in the first information.

[0094] In step S23, the network device determines suitable configuration information for the low-capability terminal device 101 according to the first information and the second information. In step S26, the terminal device 101 can determine the suitable timing for receiving and processing GNSS signals to achieve positioning according to the configuration information, and thus can also determine the timing for transmitting data.

[0095] In the embodiments of the present disclosure, the terminal device 101 may report its GNSS positioning capabilities in a non-terrestrial network (NTN) system. The network device determines appropriate configuration information based on the GNSS positioning capabilities of the terminal device 101 to effectively indicate the timing for the terminal device 101 to receive and process GNSS signals to obtain or reacquire GNSS positioning information. Thus, for low-capability terminal devices that cannot perform GNSS positioning and service data transmission simultaneously, they can receive GNSS signals and perform positioning according to the timing configured by the network device during the communication process, and can effectively perform service data transmission during other periods. Effective service data transmission can be carried out while maintaining effective uplink synchronization.

[0096] Embodiments of the present disclosure provide a method for receiving configuration information. This method is executed by the terminal device 101. This method includes:

[0097] Step S1-1: The terminal device 101 determines first information and second information; wherein, the first information corresponds to the duration required to receive Global Navigation Satellite System (GNSS) signals and obtain GNSS positioning information based on the GNSS signals, and the second information corresponds to the effective duration of the GNSS positioning information obtained by the terminal device.

[0098] Step S1-2: The terminal device 101 sends the first information and the second information to the network device.

[0099] Step S1-3: The terminal device 101 receives configuration information from the network device, where the configuration information is determined by the network device based on the first information and the second information, and the configuration information is used to indicate the timing for the terminal device to determine to receive and process GNSS signals to obtain or reacquire GNSS positioning information.

[0100] In some possible implementation manners, the first information may reflect the duration required for the terminal device 101 to receive GNSS signals and locate the position of the terminal device. The second information may reflect the effective duration of the positioning information, and the positioning information may be the position information of the terminal device located based on the GNSS signals involved in the first information. The terminal device 101 can perform GNSS positioning at the timing configured by the non-terrestrial network (NTN) device according to the configuration information.

[0101] In one implementation manner, the first information is used to indicate a first duration interval to which the duration for the terminal device to receive GNSS signals and obtain GNSS positioning information based on the GNSS signals belongs. The second information is used to indicate a second duration interval to which the effective duration of the GNSS positioning information obtained by the terminal device belongs.

[0102] In some possible embodiments, the first duration intervals corresponding to different terminal devices 101 are different, that is, the positioning capabilities of different terminal devices 101 are different. The second duration interval is related to the moving speed of the terminal device 101. For example, the faster the terminal device 101 moves, the shorter the effective duration of the positioning information.

[0103] The embodiments of the present disclosure provide a method for receiving configuration information, which is executed by the terminal device 101. This method includes steps S1-1, S1-2, and S1-3, and further includes:

[0104] Step S1-0: Receive a first mapping relationship and a second mapping relationship from the NTN device.

[0105] Among them, the first mapping relationship includes: the mapping relationship between the first level and the first duration interval.

[0106] The second mapping relationship includes: the mapping relationship between the second level and the second duration interval.

[0107] The first information is a first level in the first mapping relationship;

[0108] The second information is a second level in the second mapping relationship.

[0109] In some possible embodiments, the duration for the terminal device 101 to receive GNSS signals and obtain GNSS positioning information according to the GNSS signals is set as Ta, and the first mapping relationship includes the mapping relationship between different first levels and different first duration intervals.

[0110] In some possible embodiments, the first duration interval can be: the duration interval (t1, t2), the duration interval [t2, t3], the duration interval (t3, t4], where t1 < t2 < t3 < t4. The first level includes three levels, specifically level A, level B, and level C.

[0111] The first mapping relationship includes:

[0112] When Ta is in the duration interval [t1, t2), it corresponds to level A.

[0113] When Ta is in the duration interval [t2, t3], it corresponds to level B.

[0114] When Ta is in the duration interval (t3, t4], it corresponds to level C.

[0115] In an example, t1 = 0 seconds, t2 = 1 second, t3 = 5 seconds, t4 = 30 seconds.

[0116] In an example, the first information is A.

[0117] In one example, the first piece of information is B.

[0118] In one example, the first piece of information is C.

[0119] In some possible implementation manners, the effective duration of the GNSS positioning information obtained by the terminal device 101 is set to Td, and the second mapping relationship may be a mapping relationship including different second levels and different second duration intervals. The second duration intervals may be: the duration interval [T1, T2), the duration interval [T2, T3], the duration interval (T3, T4], the duration interval (T4, T5], where T1 < T2 < T3 < T4 < T5. The second level includes four levels, specifically level 1, level 2, level 3, and level 4.

[0120] The second mapping relationship includes: when Td is in the duration interval [T1, T2), it corresponds to level 1.

[0121] When Td is in the duration interval [T2, T3], it corresponds to level 2.

[0122] When Td is in the duration interval (T3, T4], it corresponds to level 3.

[0123] When Td is in the duration interval (T4, T5], it corresponds to level 4.

[0124] When Td corresponds to level 1, it indicates that the terminal device is moving at a high speed, so the positioning information of the terminal device has the shortest validity period.

[0125] When Td corresponds to level 2, it indicates that the terminal device is moving at a medium speed, so the positioning information of the terminal device has a relatively short validity period.

[0126] When Td corresponds to level 3, it indicates that the terminal device is moving at a low speed, so the positioning information of the terminal device has a relatively long validity period.

[0127] When Td corresponds to level 4, it indicates that the terminal device is almost stationary, so the positioning information of the terminal device has the longest validity period.

[0128] In one example, T1 = 0 second, T2 = 10 seconds, T3 = 30 seconds, T4 = 60 seconds, and T5 > 60 seconds.

[0129] In some possible implementation manners, the second mapping relationship includes:

[0130] When Td is in the duration interval [T1, T2), it corresponds to level 1.

[0131] When Td is in the duration interval [T2, T3], it corresponds to level 2.

[0132] When Td is in the duration interval (T3, T4], it corresponds to level 3.

[0133] When Td is greater than T4, it corresponds to level 4.

[0134] An embodiment of the present disclosure provides a method for receiving configuration information, which is executed by the terminal device 101. This method includes steps S1-1, S1-2, and S1-3, and further includes:

[0135] Determine a first time period interval and a second time period interval set in the communication protocol; wherein, the first time period interval corresponds to the duration for the terminal device to receive GNSS signals and obtain GNSS positioning information according to the GNSS signals, and the second time period interval corresponds to the effective duration of the GNSS positioning information obtained by the terminal device.

[0136] An embodiment of the present disclosure provides a method for receiving configuration information, which is executed by the terminal device 101. This method includes steps S1-1, S1-2, and S1-3, and further includes:

[0137] The configuration information includes first indication information and second indication information. Among them, the first indication information is used to indicate a first cycle period, and the second indication information is used to indicate a second cycle period, and the second cycle period is a sub-period in the first cycle period.

[0138] In some possible implementation manners, the duration of the first cycle period is T_d, which is related to the second time period interval corresponding to the effective duration Td of the GNSS positioning information obtained by the terminal device. The second cycle period can be denoted as GAP, the duration of the second cycle period is T_a, the second cycle period is a sub-period selected or preset within the first cycle period, and T_a is related to the first time period interval corresponding to the duration Ta for the terminal device to receive GNSS signals and obtain GNSS positioning information according to the GNSS signals.

[0139] According to the moving state of the terminal device 101, Td will change. When Td changes, the second time period interval corresponding to Td will also change, so that the first cycle period T_d will also be correspondingly different. For each first cycle period T_d, a corresponding second cycle period GAP is reserved.

[0140] An embodiment of the present disclosure provides a method for receiving configuration information, which is executed by the terminal device 101. This method includes steps S1-1, S1-2, and S1-3, and further includes:

[0141] The configuration information includes first indication information and second indication information. Among them, the first indication information is used to indicate a first cycle period, and the second indication information is used to indicate a second cycle period, and the second cycle period is a sub-period in the first cycle period.

[0142] The duration of the first cycle period is not greater than the minimum duration corresponding to the second information.

[0143] The duration of the second cycle period is not less than the maximum duration corresponding to the first information.

[0144] Exemplarily, when the effective duration of the GNSS positioning information obtained by the terminal device is Td and the corresponding level is level 2, and when determining that the second duration interval corresponding to level 2 is [T2, T3], then T_d satisfies: T_d ≤ the minimum value of [T2, T3], that is, T_d ≤ T2.

[0145] Exemplarily, when the first duration Ta corresponding to the GNSS signal received by the terminal device and the GNSS positioning information obtained according to the GNSS signal is level B, and when determining that the first duration interval corresponding to level B is [t2, t3], then T_a satisfies: T_a ≥ the maximum value of [t2, t3], that is, T_a ≥ t3.

[0146] In the embodiments of the present disclosure, the set duration of the second cycle period GAP and the set period can be determined. The second cycle period GAP can be used as a reserved period for positioning according to the GNSS signal. During this period, the terminal device 101 can receive the GNSS signal and perform positioning according to the GNSS signal.

[0147] The embodiments of the present disclosure provide a method for receiving configuration information, which is executed by the terminal device 101. This method includes steps S1-1, S1-2, and S1-3, and further includes: the configuration information includes first indication information and second indication information. Among them, the first indication information is used to indicate the first cycle period, and the second indication information is used to indicate the second cycle period. The second cycle period is a sub-period in the first cycle period. The first cycle period corresponds to consecutive radio frames, and the frame number of the starting radio frame or the ending radio frame in the consecutive radio frames meets the first setting condition; the second cycle period corresponds to a sub-period within the first cycle period that meets the second setting condition.

[0148] In some possible implementation manners, the first setting condition can indicate the position of the first cycle period, and the second setting condition indicates the position of the second cycle period within the first cycle period.

[0149] For different first cycle periods, the configured positions of the second cycle period in each first cycle period can be the same or different. The duration of the second cycle period can be represented by the number of radio frames.

[0150] In one example, each first cycle period occupies 10 radio frames, and the serial numbers of the radio frames occupied by the second cycle period in each first cycle period are the same. For example, they are all located in the first radio frame to the third radio frame among the 10 radio frames. In this example, the occupied duration and position of the second cycle period in the first cycle period are the same.

[0151] In another example, each first cycle period occupies 10 radio frames, and the serial numbers of the radio frames occupied by the second cycle period in at least two first cycle periods are different. For example, the radio frames occupied by the second cycle period in a part of the first cycle periods are the first radio frame to the third radio frame, and the radio frames occupied by the second cycle period in another part of the first cycle periods are the first radio frame to the fourth radio frame.

[0152] In another example, the first cycle period includes two discontinuous parts, and each part includes a plurality of consecutive radio frames. For example: the first part includes 10 radio frames, and the second part includes 20 radio frames. Then, for one first cycle period, the occupied position of its second cycle period can be located in the first part. For another first cycle period, the occupied position of its second cycle period can be located in the second part.

[0153] In some possible implementation manners, the first setting condition includes: the remainder value of the modulo operation of the frame number of the starting radio frame or the ending radio frame and the first value is the second value; the first indication information includes: the number of consecutive radio frames corresponding to the first cycle period, the first value, and the second value.

[0154] In some possible implementation manners, the modulo operation can be expressed as: mod(frame number of the starting radio frame, M) = m, where M is the first value and m is the second value. According to the frame number of the starting radio frame, M, and m being different, the operation results may be different.

[0155] According to the operation result, the positions of the starting radio frame and the ending radio frame of the first cycle period can be determined respectively. For example, when m = 0, that is, when mod(frame number of the starting radio frame, M) = 0, the frame numbers of the starting radio frame are M, 2M, 3M, etc.

[0156] In some possible implementation manners, the second setting condition includes: the sub-period includes consecutive sub-frames, and the number of consecutive sub-frames is the third value; the second indication information includes: the third value.

[0157] In this embodiment, the duration occupied by the second cycle period GAP is characterized by the number of sub-frames, that is, the third value.

[0158] In some possible embodiments, the second set condition includes: the sub-period includes consecutive sub-frames, the number of consecutive sub-frames is a third value, and the number of offset sub-frames of the starting sub-frame of the consecutive sub-frames from the first sub-frame of the starting radio frame in the first period is a fourth value; the second indication information includes: the third value and the fourth value.

[0159] Wherein, the duration of the second period GAP is a third value. And the fourth value can characterize the starting position of the second period within the first period.

[0160] In an example, the first period occupies 10 radio frames. When the third value is i (i < 10), it indicates that the second period occupies i consecutive sub-frames within the first period. When the fourth value is j (j < 10), it indicates that the starting sub-frame of the i consecutive sub-frames occupied by the second period is offset by j sub-frames relative to the first sub-frame of the starting radio frame.

[0161] The following is described with a specific example.

[0163] The NTN device determines configuration information according to the first information and the second information. The configuration information includes first indication information and second indication information. The first indication information includes 10, 5, 0 in sequence. The second indication information includes 3 and 2 in sequence. Among them, 10 in the first indication information indicates that the duration of the first period T_d is the duration corresponding to 10 radio frames, and this duration is less than or equal to T2; the second period T_a in the second indication information is greater than or equal to t3.

[0164] The NTN device sends the configuration information to the terminal device 101.

[0165] After receiving the configuration information from the NTN device, the terminal device 101 learns from the first indication information that the first period T_d corresponds to 10 radio frames, and the frame numbers of the starting radio frames of the first period T_d are 0, 5, 10, 15, etc. From the second indication information, it learns that the second period occupies 3 consecutive sub-frames within the first period, and the starting sub-frame of the 3 consecutive sub-frames occupied by the second period is offset by 2 sub-frames relative to the first sub-frame of the first radio frame in the first period.
