[0004] --Title of the invention of the original application: A method and device used in a node for wireless communication Technical Field

[0005] The present application relates to a transmission method and device in a wireless communication system, and more particularly to a transmission scheme and device with large delay in wireless communication. Background Art

[0006] In the future, the application scenarios of wireless communication systems will become more and more diversified, and different application scenarios will put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to study the new radio (NR) (or 5G), and the WI (Work Item) of the new radio (NR) was passed at the 3GPP RAN #75 plenary meeting, and the standardization work on NR began.

[0007] In order to adapt to various application scenarios and meet different needs, the 3GPP RAN#75 plenary meeting also passed the study project of non-terrestrial networks (NTN) under NR, which started in the R15 version. At the 3GPP RAN#79 plenary meeting, it was decided to start studying solutions in NTN networks, and then start WI in the R16 or R17 version to standardize related technologies. Summary of the invention

[0008] In NTN networks or networks similar to NTN with large transmission delays and large transmission delay differences, the large transmission delay differences and the requirement for uplink and downlink synchronous transmission may make it impossible to directly reuse existing designs based on traditional terrestrial networks (such as NR 5G Release 16). Therefore, new designs are needed to support large transmission delays and ensure normal communication.

[0009] The present application discloses a solution to the problem that existing designs in long-latency networks cannot work or cannot work effectively due to long delays and long delay differences. It should be noted that in the description of the present application, only the NTN scenario is used as a typical application scenario or example; the present application is also applicable to other scenarios outside of NTN that face similar problems (such as other long-latency networks), and can also achieve similar technical effects in the NTN scenario. In addition, the use of a unified solution for different scenarios (including but not limited to NTN scenarios) can also help reduce hardware complexity and costs. In the absence of conflict, the embodiments and features in the first node device of the present application can be applied to the second node device, and vice versa. In particular,

[0010] For the interpretation of the terminology, nouns, functions, and variables in this application (unless otherwise specified), reference may be made to the definitions in the 3GPP specification protocols TS36 series, TS38 series, and TS37 series.

[0011] The present application discloses a method in a first node in wireless communication, characterized by comprising:

[0014] Sending a first signal;

[0015] Among them, the first characteristic parameter group includes at least one of the type of the sender of the first information, the height of the sender of the first information, and a common time offset; the first time length set is one of X alternative time length sets, and X is a positive integer greater than 1; the first characteristic parameter group is used to determine the first time length set from the X alternative time length sets; any one of the X alternative time length sets includes a positive integer number of time lengths greater than 1, and the target time length is one of the first time length sets; the target time length and the common time offset are used together to determine the length of the time interval between the reception time of the first signaling and the transmission time of the first signal.

[0016] As an embodiment, by introducing the X sets of alternative time lengths, the configuration of the first set of time lengths under different delay conditions is supported, so that the network can configure the delay of the uplink and downlink conversion that can be scheduled according to the actual delay conditions.

Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to as PHY301 in this article. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the first node device and the second node device through PHY301.

The signal transmission processing function includes encoding and interleaving to facilitate forward error correction (FEC) at UE450 and modulating the baseband signal based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK)), dividing the modulation symbols into parallel streams and mapping each stream to a corresponding multi-carrier subcarrier and / or multi-carrier symbol, and then mapping to the antenna 460 via the transmitter 456 by the transmit processor 455 to transmit in the form of a radio frequency signal. The receiver 416 receives the radio frequency signal through its corresponding antenna 420, and each receiver 416 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to the receive processor 412. The receiving processor 412 implements various signal receiving and processing functions for the L1 layer (i.e., the physical layer), including receiving and processing the physical layer signals of the first signal and the third signal in the present application and processing the uplink control information carried by the third signal.
