To facilitate a better understanding of the embodiments of the present application, the NTN related to the present application is described.

NTN generally adopts satellite communication to provide communication services to ground users. Compared with terrestrial cellular network communication, satellite communication has many unique advantages. First of all, satellite communication is not restricted by the user's region. For example, general land communication cannot cover areas such as oceans, mountains, deserts, etc. that cannot be equipped with communication equipment or are not covered by communication due to sparse population. For satellite communication, due to a Satellites can cover a large area of the ground, and satellites can orbit the earth, so theoretically every corner of the earth can be covered by satellite communications. Secondly, satellite communication has great social value. Satellite communication can be covered at a lower cost in remote mountainous areas, poor and backward countries or regions, so that people in these regions can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital gap with developed regions and promoting development of these areas. Thirdly, the distance of satellite communication is long, and the cost of communication does not increase significantly with the increase of communication distance; finally, the stability of satellite communication is high, and it is not limited by natural disasters.

Communication satellites are divided into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, and high elliptical orbit satellites according to their orbital heights. (High Elliptical Orbit, HEO) satellites and so on.

Low orbit satellites (LEO) range in altitude from 500km to 1500km, and the corresponding orbit period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between users is generally less than 20ms. The maximum satellite visible time is 20 minutes. The signal propagation distance is short, the link loss is small, and the requirements for the transmission power of the user terminal equipment are not high.

Geosynchronous Orbit (GEO) satellites have an orbital altitude of 35786km and a 24-hour rotation period around the Earth. The signal propagation delay of single-hop communication between users is generally 250ms.

In order to ensure satellite coverage and improve the system capacity of the entire satellite communication system, satellites use multi-beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover tens to hundreds of kilometers in diameter. ground area.

In order to better understand the embodiment of the present application, the timing relationship of the NTN system related to the present application will be described.

In land communication systems, the propagation delay of signal communication is usually less than 1 ms. In the NTN system, because the communication distance between the terminal equipment and the satellite (or network equipment) is very long, the propagation delay of signal communication is very large, ranging from tens of milliseconds to hundreds of milliseconds, depending on the satellite orbital height and The business type of satellite communication is related. In order to deal with relatively large propagation delays, the timing relationship of the NTN system needs to be enhanced relative to the NR system.

In the NTN system (such as NR-NTN system or Internet of Things NTN (Internet of Things NTN, IoT-NTN) system), like the NR system, UE needs to consider the impact of timing advance (Timing Advance, TA) when performing uplink transmission . Since the propagation delay in the system is relatively large, the range of the TA value is also relatively large. When the UE is scheduled to perform uplink transmission in time unit (such as time slot or subframe) n, the UE considers the round-trip propagation delay and transmits in advance during uplink transmission, so that the uplink transmission on the network device side can be realized when the signal arrives at the network device side time unit n. Specifically, the timing relationship in the NTN system may include two situations, as shown in Fig. 2 and Fig. 3 below respectively.

Case 1 As shown in FIG. 2 , the downlink (downlink, DL) time unit and the uplink (uplink, UL) time unit on the network device side are aligned. Correspondingly, in order to make the uplink transmission of the UE arrive at the network device side aligned with the uplink time unit of the network device side, the UE needs to use a larger TA value. In some cases, the TA value corresponds to an offset value Koffset.

Case 2 is shown in FIG. 3 , there is an offset value between the downlink time unit and the uplink time unit on the network device side. In this case, if the uplink transmission of the UE is to be aligned with the uplink time unit of the network device when it arrives at the network device side, the UE only needs to use a smaller TA value. In some cases, the TA value corresponds to an offset value Koffset. In other cases, the RTT of the UE corresponds to the offset value Koffset.

In order to better understand the embodiment of the present application, the timing adjustment in the NTN system related to the present application will be described.

In the NTN system, network equipment needs to send synchronization assistance information such as ephemeris information (satellite moving speed and/or satellite position), reference point position, public timing value (such as timing value between network equipment and reference point, and/or, the timing value between the network equipment and the satellite, and/or, the timing value between the satellite and the reference point (in some cases, also known as the timing value of the feeder link), time At least one item of information such as a timestamp (timestamp) is used for the terminal device to complete time domain and/or frequency domain synchronization. Correspondingly, the terminal device needs to obtain the synchronization assistance information sent by the network device, and at the same time complete corresponding time domain and/or frequency domain synchronization according to its own GNSS capability. A terminal device should obtain at least one of the following information based on its GNSS capabilities: position, time reference and frequency reference of the terminal device. Moreover, based on the above information, as well as the synchronization assistance information indicated by the network device (such as ephemeris information or time stamp of the serving satellite), the terminal device can calculate the timing and/or frequency offset, and apply the timing in the idle state or the inactive state or the connected state. Advance compensation and/or frequency offset adjustment.

In some cases, the terminal device may calculate the TA value according to the following formula, and perform uplink channel or uplink signal transmission according to the determined TA.

T _TA ＝(N _TA +N _{TA,UE-specific} +N _TA,offset +N _TA,common )*Tc

Among them, N _{TA, UE-specific} can be the TA value estimated by the terminal equipment itself, for example, it is used to determine the timing value of the service link (service link), N _{TA, offset} is the same as the existing protocol, for example, it is based on the network deployment frequency band and LTE Or determined by NR coexistence, N _TA,common includes the public timing value broadcast by the network equipment, for example, used to determine the timing value of the feeder link, N _TA can be the TA value indicated by the network equipment (wherein if the uplink channel includes PRACH or MsgA transmission, the value of N _TA is 0). Tc represents the sampling time interval unit, Tc=1/(480*1000*4096).

That is to say, the terminal device needs to jointly estimate or update the TA according to at least one of the TA value estimated by the terminal device itself, the public timing offset value, and the TA value indicated by the network device.

FIG. 4 shows a schematic diagram of the timing relationship between the downlink frame and the uplink frame of the terminal equipment in the NTN system.

In related technologies, network devices need to broadcast a public timing value, which is used to determine TA adjustment when terminal devices in an idle state, inactive state, or connected state perform uplink channel or uplink signal transmission. However, how to notify the public timing value, for example, how to determine the granularity corresponding to the notification of the public timing value, so that terminal equipment in the idle state, inactive state or connected state can complete the corresponding TA when performing uplink channel or uplink signal transmission Adjustment is an urgent problem.

FIG. 5 is a schematic interaction diagram of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 5 , the wireless communication method 200 may include at least part of the following content:

S210. The network device sends first information to the terminal device, where the first information is used to indicate a first timing value according to the first subcarrier spacing;

Correspondingly, the terminal device receives the first information sent by the network device.

S220. The terminal device determines the first timing value according to the first information sent by the network device;

S230. The terminal device determines timing information of the first uplink transmission according to the first timing value.

Further, the first uplink transmission may be performed based on timing information of the first uplink transmission.

The embodiment of the present application can be applied to the NTN network, or can also be applied to other networks that need to adjust the timing information, which is not limited in the present application.

It should be understood that the embodiment of the present application may be applied to a terminal device in any state, for example, a terminal device in an idle state, and/or a terminal device in an inactive state, and/or a terminal device in a connected state.

In some embodiments of the present application, the first information is sent through a system message or a public radio resource control (Radio Resource Control, RRC) message. For example, the first information may be cell-level information, that is, the first information may be applicable to all terminal devices in the cell. In this case, the first information may be sent through a public message or channel.

In some embodiments of the present application, the first subcarrier spacing is determined according to at least one of the following:

The subcarrier spacing corresponding to the first frequency band;

The subcarrier spacing corresponding to the first bandwidth part (Band Width Part, BWP);

For example, the first subcarrier interval is determined according to a first frequency band, and the first frequency band is a frequency band used by a system corresponding to the network device to provide services.

As an example, the first subcarrier spacing is the maximum subcarrier spacing supported by the first frequency band.

As yet another example, the first subcarrier spacing is the minimum subcarrier spacing supported by the first frequency band.

For example, if the subcarrier spacing supported by the system corresponding to the network device on the first frequency band includes {15kHz, 30kHz}, and the first subcarrier spacing is the maximum subcarrier spacing supported by the first frequency band, then the first subcarrier spacing is 30kHz .

For another example, if the subcarrier spacing supported by the system corresponding to the network device on the first frequency band includes {60kHz, 120kHz}, and the first subcarrier spacing is the maximum subcarrier spacing supported by the first frequency band, then the first subcarrier spacing is 120kHz.

For another example, if the subcarrier spacing supported by the system corresponding to the network device on the first frequency band includes {15kHz, 30kHz, 60kHz, 120kHz}, and the first subcarrier spacing is the maximum subcarrier spacing supported by the first frequency band, then the first The subcarrier spacing is 120kHz.

In some embodiments, the first subcarrier spacing is associated with a first BWP. For example, the first subcarrier spacing is determined according to the first BWP.

As an example, the first BWP is an initial downlink BWP. For example, the first subcarrier spacing is a subcarrier spacing corresponding to downlink transmission on the initial downlink BWP. Wherein, the downlink transmission may be any downlink channel or signal transmission except a synchronization signal block (Synchronization Signal/physical broadcast channel Block, SS/PBCH block or SSB).

As an example but not a limitation, the downlink transmission may include at least one of the following:

Physical Downlink Shared Channel (PDSCH), Physical Downlink Control Channel (PDCCH), Channel State Information Reference Signal (CSI-RS).

For example, if the subcarrier interval corresponding to the PDSCH transmission carrying system information on the initial downlink BWP is 30 kHz, then the first subcarrier interval is 30 kHz.

As another example, the first BWP is an initial uplink BWP. For example, the first subcarrier spacing is the subcarrier spacing corresponding to the uplink transmission on the initial uplink BWP. The uplink transmission may be any uplink channel or signal transmission.

As an example but not a limitation, the uplink transmission may include at least one of the following:

Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Physical Random Access Channel (Physical Random Access Channel, PRACH), Sounding Reference Signal (SRS) .

For example, if the subcarrier spacing corresponding to the PUSCH transmission on the initial uplink BWP is 15 kHz, then the first subcarrier spacing is 15 kHz.

In some embodiments, the first subcarrier spacing is determined according to a subcarrier spacing corresponding to SSB transmission. For example, if the subcarrier spacing corresponding to SSB transmission is 30 kHz, then the first subcarrier spacing is 30 kHz.

In some embodiments, the first subcarrier spacing is determined according to the subcarrier spacing corresponding to the first uplink transmission after the terminal device receives the RAR. For example, if the subcarrier interval corresponding to the first uplink transmission after the terminal device receives the RAR is 15 kHz, then the first subcarrier interval is 15 kHz.
