[0066] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0067] In NTN systems, due to the significant time delay between the base station and the terminal equipment, the terminal equipment needs to send the uplink signal with a timing advance (TA) before sending the uplink signal to ensure that the signal arrives at the base station (e.g., gNB) at the correct time. However, if the timing advance is too large, it can affect the uplink and downlink timing relationship, resulting in the uplink signal being sent before the downlink signal arriving. Therefore, a timing advance parameter (K) is introduced. offset Enhance existing timing relationships, for example, the gNB obtains K from the TA reported by the terminal device. offset And then use K offset Enhance timing relationships in the NTN system. The temporal resource granularity of TA is T. c At the same time, determine K offset The temporal resource granularity is determined to be a slot, and the temporal resource granularity of the reported TA content is also determined to be a slot.

[0068] To facilitate a better understanding of the embodiments of this application, the following will be used as examples. Figure 2 and Figure 3 For example, satellite (SAT) communication in two scenarios is described respectively.

[0069] Scenario 1: SAT access transparent forwarding mode

[0070] Figure 2This diagram illustrates a scenario in an NTN system including a SAT communication system, where a single SAT is used for transparent forwarding. As shown in the figure, only one SAT exists in the communication link between the terminal device and the base station (gNB), and the SAT does not process the received information, only performing transparent forwarding. In scenario 1, the base station (gNB) is still deployed on the ground. When the terminal device communicates with the base station (gNB), the SAT forwards the signal. The SAT does not process the received information; in this case, the SAT acts as a relay node or repeater. This scenario can be called transparent payload mode. In this transparent payload mode, the SAT only transparently forwards the received signal, and the ground base station transmits the forwarded signal to the core network. Conversely, information transmitted back from the core network to the terminal device is also transmitted to the terminal device via transparent forwarding by the SAT.

[0071] Scenario 2: SAT access regeneration forwarding mode

[0072] Figure 3 This diagram illustrates a scenario in an NTN network including a SAT communication system, where multiple SATs are used for regeneration and forwarding. As shown, SAT-1 and SAT-2 integrate all or part of the base station functions and are connected to the core network via an NTN gateway (also known as a terrestrial gateway). Unlike the transparent forwarding mode, SAT-1 and / or SAT-2 can process the received information. Optionally, these processing steps include, but are not limited to, operations performed by the original terrestrial base station, such as encrypting, decrypting, padding, and / or changing information parameters. Furthermore, as shown, SAT-1 is the satellite connecting to the terminal equipment, and SAT-2 is the satellite connecting to the core network. Optionally, when forwarding information from the terminal equipment, SAT-1 forwards the information to SAT-2, which then forwards it to the core network. Optionally, during the aforementioned information forwarding process, SAT-1 and / or SAT-2 can perform corresponding processing on the forwarded information. Conversely, information transmitted back from the core network to the terminal equipment is also forwarded to the terminal equipment via SAT-2 and SAT-1, where SAT-1 and / or SAT-2 can perform corresponding processing on the forwarded information. This SAT access regenerative forwarding mode shown in Scenario 2 can also be called the regenerative payload mode.

[0073] It is readily understood by those skilled in the art. Figure 3 Only two satellites, SAT-1 and SAT-2, are shown schematically. Optionally, in Figure 3The satellite access regeneration forwarding mode shown may include two or more SATs. For example, the information transmission path between SAT-1 and SAT-2 may also include one or more other satellites SAT-3, SAT-4, SAT-5...SAT-n, each of which can transparently forward and / or process the received information. SAT-1 and SAT-2 may form one or more satellite transmission paths with at least one of one or more satellites SAT-3, SAT-4, SAT-5...SAT-n. For example, satellite transmission path SAT path-1 includes satellites SAT-1, SAT-3, and SAT-2; satellite transmission path SAT path-2 includes satellites SAT-1, SAT-4, and SAT-2; satellite transmission path SAT path-3 includes satellites SAT-1, SAT-3, SAT-4, and SAT-2, etc. In this paper, adjacent satellites in each satellite transmission path are connected via inter-satellite links (ISLs), and each ISL corresponds to one satellite hop.

[0074] To facilitate a better understanding of the embodiments of this application, the problems solved by this application will be explained.

[0075] In NTN systems, due to the significant time delay between satellites and terminals, a timing offset (K) is introduced. offset To enhance timing relationships in NTN systems, the network side can determine timing offset values ​​(K) based on the timing advance (TA) reported by the terminal. offset However, due to the terminal reporting the time offset value (K) used to determine the timing offset value. offset The temporal granularity of the information and the temporal offset value (K) offset The inconsistent temporal granularity of K makes it difficult for network devices to determine the timing offset value (K). offset ).

[0076] The technical solution of this application is described in detail below through specific embodiments.

[0077] Figure 4 This is a schematic flowchart of a wireless communication method 200 according to an embodiment of this application, such as... Figure 4 As shown, the wireless communication method 200 may include at least some of the following:

[0078] S210, the terminal device sends first information to the network device, the first information being used to determine a timing offset value; wherein, the first information is a first parameter of a first time domain granularity, and / or, the first information is a second parameter of a first time domain granularity, the first time domain granularity being a time domain granularity associated with a subcarrier, the first parameter being used to represent the estimated delay of the terminal device on the serving link, and the second parameter being used to represent TA;

[0079] S220, the network device receives the first information sent by the terminal device.

[0080] In this embodiment of the application, the network device determines the timing offset value (K) based on a first parameter at a first time-domain granularity. offset ), and / or, the network device determines the timing offset value (K) based on the second parameter at the first time-domain granularity. offset Furthermore, the network device can use the determined timing offset value (K) offset ) Configure or instruct the terminal device, so that the terminal device can, based on the timing offset value (K offset Uplink transmission is then performed. For example, suppose the network device schedules the terminal device to send uplink data in time slot n (time slot n is the time slot after TA synchronization). In this case, the terminal device needs to be upgraded to time slot n+K. offset Uplink data is sent to avoid uplink transmissions by terminal devices occurring before downlink scheduling. Wherein, K... offset Greater than or equal to the TA of the terminal device.

[0081] In some embodiments, the timing offset value (K) offset The temporal granularity of ) is also related to the subcarrier.

[0082] In this embodiment, the time-domain granularity of the first or second parameter reported by the terminal device for determining the timing offset value is a time-domain granularity associated with the subcarrier, and the time-domain granularity of the timing offset value is also associated with the subcarrier. That is, the terminal device can use its reported parameters for determining the timing offset value (K) to determine the timing offset value. offset The temporal granularity of the information is converted to that of the temporal offset value (K). offset The consistency of the temporal granularity of the data facilitates the determination of the timing offset value (K) by network devices. offset ).

[0083] In some embodiments, the first time-domain granularity is a time slot, or the first time-domain granularity is another time-domain granularity associated with a subcarrier or subcarrier spacing, which is not limited in this application.

[0084] It should be noted that the service link can be a communication link between the terminal device and the satellite, such as... Figure 2 and Figure 3 As shown.

[0085] In some embodiments, the first information may be carried by one of the following:

[0086] Uplink Control Information (UCI), Radio Resource Control (RRC) signaling, and Media Access Control Control Element (MAC CE) signaling.

[0087] Specifically, for example, the first information may be one or more information elements (IEs) in the signaling carrying the first information, such as a field, element, or domain.

[0088] In some embodiments, when the first information includes the first parameter of the first time domain granularity, the terminal device converts the time domain resource granularity of the first parameter from the second time domain granularity to the first time domain granularity to obtain the first parameter of the first time domain granularity.

[0089] That is, the terminal device initially obtains the first parameter at the second time domain granularity. Then, the terminal device converts the time domain resource granularity of the first parameter from the second time domain granularity to the first time domain granularity to obtain the first parameter at the first time domain granularity.

[0090] In some embodiments, the time-domain granularity of the first parameter is T. c Or seconds (s), of course, the time-domain granularity of the first parameter can also be other, and this application does not limit it.

[0091] In some embodiments, the T c The time unit is as agreed upon in the agreement.

[0092] For example, T c =1 / (Δf) max ·N f ), where Δf max =480·10 3 Hz, N f =4096.

[0093] Of course, Δf max and N f Other values ​​are also possible, but this application does not limit them.

[0094] In some embodiments, the first time-domain granularity is a time slot, and the second time-domain granularity is T. c .

[0095] In some embodiments, the first parameter is N.TA,UE-specific That is, N TA,UE-specific Used to represent the estimated latency of the terminal device on the service link.

[0096] In other words, N TA,UE-specific This is the UE's self-estimated TA (Time Acquisition) used to pre-compensate for the service link delay.

[0097] In some embodiments, the terminal device adjusts the temporal resource granularity of the first parameter from T according to the following formula 1. c Convert to time slot:

[0098]

[0099] Where, N TA,UE-specific For this first parameter, μ represents the subcarrier spacing configuration. This indicates rounding up to the nearest integer.

[0100] That is, in Formula 1 above,

[0101] In some embodiments, the correspondence between μ, subcarrier Δf, and time slot can be as shown in Table 1.

[0102] Table 1

[0103] μ <![CDATA[Δf=2 μ ·15[kHz]]]> Number of time slots contained in a subframe 0 15 1 1 30 2 2 60 4 3 120 8 4 240 16

[0104] It should be noted that the correspondence in Table 1 above can also be applied to Δf = 480kHz or Δf = 960kHz, or Δf for other values, and this application does not limit this.

[0105] In some embodiments, when the first information includes the second parameter at the first time-domain granularity, the terminal device determines the second parameter at the first time-domain granularity based on the time-domain granularity of the target parameter.

[0106] The target parameter includes at least one of the following: N TA N TA,UE-specific N TA,common N TA,offset ;

[0107] Where, N TA N represents the parameters related to TA configured on the network device. TA,UE-specific N represents the estimated latency of the service link for this terminal device. TA,common N represents the time delay between the satellite and the reference point. TA,offset This represents the fixed offset value used to calculate TA.

[0108] For example, N TA It is obtained from the TA self-estimation specific to the terminal device. For the Physical Random Access Channel (PRACH), N TA Defined as 0, and N TA Update based on the TA command field and MAC CE TA command in message 2 (msg2) of the four-step random access or message B (msgB) of the two-step random access.

[0109] For example, N TA,common This represents the time delay between the satellite and the reference point. If the network broadcasts N... TA,common Then N TA,common It is obtained at least from the common timing offset value, and may also include some timing offsets from the network side. In other words, N TA,common A common timing offset controlled by network devices, and may include any timing offsets deemed necessary by the network side. TA,common The value of can be 0.
