In NTN systems, network devices need to broadcast a common timing value for TA adjustment when an uplink channel or uplink signal is transmitted by a terminal device in an idle state or inactive state or in a connected state. However, how to notify the common timing value so that the terminal device in idle state or inactive state or connected state can complete the corresponding TA adjustment when transmitting the uplink channel or uplink signal is a problem to be solved.

To facilitate a better understanding of embodiments of the present application, NTNs relevant to the present application will be described.

NTN typically provides communication services to terrestrial users by way of satellite communications. Satellite communications have many unique advantages over terrestrial cellular communications. First, satellite communications are not limited by the user region, for example, general land communications cannot cover areas where communication devices cannot be installed, such as oceans, mountains, deserts, etc., or communication coverage is not performed due to rarity of population, while for satellite communications, since one satellite can cover a larger ground, and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communications. And secondly, satellite communication has great social value. Satellite communication can be covered in remote mountain areas, poor and backward countries or regions with lower cost, so that people in the regions enjoy advanced voice communication and mobile internet technology, and the digital gap between developed regions is reduced, and the development of the regions is promoted. Again, the satellite communication distance is far, and the cost of communication is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into Low Earth Orbit (LEO) satellites, medium Earth Orbit (MEO) satellites, geosynchronous Orbit (Geostationary Earth Orbit, GEO) satellites, high elliptical Orbit (High Elliptical Orbit, HEO) satellites, and the like according to the Orbit heights.

The low orbit satellite (LEO) altitude range is 500 km-1500 km, with corresponding orbit periods of about 1.5 hours-2 hours. The signal propagation delay for single hop communications between users is typically less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the user terminal equipment is not high.

Geosynchronous orbit (GEO) satellites have an orbit height of 35786km and a period of 24 hours around the earth. The signal propagation delay for single hop communications between users is typically 250ms.

In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form tens or hundreds of beams to cover the ground; a satellite beam may cover a ground area of several tens to hundreds of kilometers in diameter.

To facilitate a better understanding of the embodiments of the present application, the timing relationships of the NTN systems associated with the present application are described.

In terrestrial communication systems, the propagation delay of signal communications is typically less than 1ms. In NTN systems, due to the long communication distance between the terminal device and the satellite (or network device), the propagation delay of the signal communication is large, which may range from tens of milliseconds to hundreds of milliseconds, in particular in relation to the satellite orbit height and the type of service of the satellite communication. In order to handle the relatively large propagation delays, the timing relationship of NTN systems needs to be enhanced relative to NR systems.

In NTN systems (for example, NR-NTN system or internet of things NTN (Internet of Things NTN, ioT-NTN) system), as in NR systems, the UE needs to consider the impact of Timing Advance (TA) when performing uplink transmission. The range of TA values is also relatively large due to the large propagation delay in the system. When a UE is scheduled for uplink transmission in a time unit (e.g., a slot or a subframe) n, the UE considers round trip propagation delay, and transmits in advance in uplink transmission, so that a signal can arrive at the network device side on the time unit n uplink on the network device side. Specifically, the timing relationship in the NTN system may include two cases, as shown in fig. 2 and 3, respectively.

Case 1 as shown in fig. 2, a Downlink (DL) time unit and an Uplink (UL) time unit on the network device side are aligned. Accordingly, in order to align the uplink time unit of the UE with the uplink time unit of the network device side when the uplink transmission of the UE arrives at the network device side, the UE needs to use a larger TA value. In some cases, the TA value corresponds to the offset value Koffset.

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

To facilitate a better understanding of embodiments of the present application, timing adjustments in NTN systems related to the present application are described.

In NTN systems, the network device needs to send synchronization assistance information, such as at least one of ephemeris information (satellite movement speed and/or satellite position), reference point position, common timing values (e.g. timing values between the network device and the reference point, and/or between the network device and the satellite, and/or between the satellite and the reference point, in some cases also called timing values of feeder link), time stamp (time stamp), etc. to the terminal device for the terminal device to complete time-domain and/or frequency-domain synchronization. Correspondingly, the terminal equipment needs to acquire the synchronization auxiliary information sent by the network equipment, and meanwhile, the corresponding time domain and/or frequency domain synchronization is completed according to the GNSS capability of the terminal equipment. The terminal device should obtain at least one of the following information based on its GNSS capabilities: location of the terminal device, time reference and frequency reference. And based on the above information, and synchronization assistance information (e.g., service satellite ephemeris information or time stamps) indicated by the network device, the terminal device may calculate timing and/or frequency offset and apply timing advance compensation and/or frequency offset adjustment in an idle state or inactive state or connected state.

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

Wherein N is _{TA,UE-specific} May be a TA value estimated by the terminal device itself, e.g. a timing value for determining a service link, N _TA,offset As in the existing protocol, for example, is determined according to the frequency band of the network and the coexistence of LTE or NR, N _TA,common Comprising common timing values broadcast by network devices, e.g. for determining timing values of feeder links, N _TA May be a TA value indicated by the network device (where N if the uplink channel includes PRACH or MsgA transmissions _TA Take a value of 0). Tc represents a sampling time interval unit, tc=1/(480×1000×4096).

That is, the terminal device needs to jointly estimate or update the TA according to at least one of the TA value obtained by the self-estimation of the terminal device, the common 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 device in the NTN system.

In the related art, a network device needs to broadcast a common timing value for determining TA adjustment when an idle state or inactive state or connected state terminal device performs uplink channel or uplink signal transmission. However, how to notify the common timing value, for example, how to determine the granularity corresponding to the notification of the common timing value, so that the terminal device in idle state or inactive state or connected state can complete the corresponding TA adjustment when performing uplink channel or uplink signal transmission is an urgent problem to be solved.

Fig. 5 is a schematic interaction diagram of a method 200 of wireless communication according to an embodiment of the present application, as shown in fig. 5, the method 200 of wireless communication may include at least some of the following:

s210, the network equipment sends first information to the terminal equipment, wherein the first information is used for indicating a first timing value according to a first subcarrier interval;

correspondingly, the terminal equipment receives the first information sent by the network equipment.

S220, the terminal equipment determines the first timing value according to first information sent by the network equipment;

and S230, the terminal equipment determines the 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 application can be applied to NTN networks or other networks needing timing information adjustment, and the application is not limited to this.

It should be understood that the embodiments of the present application may be applied to any state of terminal equipment, for example, idle state terminal equipment, and/or inactive state terminal equipment, and/or connected state terminal equipment.

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

In some embodiments of the application, the first subcarrier spacing is determined in accordance with at least one of:

subcarrier spacing corresponding to the first frequency band;

a subcarrier interval corresponding to a first bandwidth Part (BWP);

the synchronization signal block SSB transmits the corresponding subcarrier spacing;

the terminal equipment receives the subcarrier interval corresponding to the first uplink transmission after the random access response (Random Access Response, RAR);

subcarrier intervals corresponding to the timing values indicated by the RAR;

and the network equipment corresponds to the system.

In some embodiments, the first subcarrier spacing has an association with a frequency band. For example, the first subcarrier spacing is determined according to a first frequency band, where the first frequency band is a frequency band used for providing services for a system corresponding to the network device.

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

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

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

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

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

In some embodiments, the first subcarrier spacing has an association with a first BWP. For example, the first subcarrier spacing is determined in accordance with a 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 other than a synchronization signal block (Synchronization Signal/physical broadcast channel Block, SS/PBCH block or SSB).

By way of example and not limitation, the downlink transmission may include at least one of:

a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), a physical downlink control channel (Physical Downlink Control Channel, PDCCH), a channel state information reference signal (Channel State Information Reference Signal, CSI-RS).

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

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

By way of example and not limitation, the uplink transmission may include at least one of:

physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), physical uplink control channel (Physical Uplink Control Channel, PUCCH), physical random access channel (Physical Random Access Channel, PRACH), sounding reference signal (Sounding Reference Signal, SRS).

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

In some embodiments, the first subcarrier spacing is determined from a subcarrier spacing corresponding to SSB transmissions. For example, the SSB transmission corresponds to a subcarrier spacing of 30kHz, and the first subcarrier spacing is 30kHz.

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

In some embodiments, the first subcarrier spacing is determined according to a subcarrier spacing corresponding to a timing value in an RAR sent by the network device. For example, if the timing indication TA included in the RAR corresponds to a subcarrier spacing of 15kHz, the first subcarrier spacing is 15kHz.
