Description

Method and device in communication node for wireless communication
Technical Field
The present application relates to transmission methods and arrangements in wireless communication systems, and more particularly to transmission schemes and arrangements with large delay differences.
Background
In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of multiple application scenarios, a New air interface technology (NR, New Radio) (or 5G) is determined to be studied in 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 guilds, and standardization Work on NR starts after passing through WI (Work Item) of the New air interface technology (NR, New Radio) in 3GPP RAN #75 guilds.
In order to be able to adapt to various application scenarios and meet different requirements, the 3GPP RAN #75 time congress also passed a Non-Terrestrial Networks (NTN) research project under NR, which started in version R15. The decision to start the study of solutions in NTN networks was made on 3GPP RAN #79 full meeting, and then WI was initiated to standardize the related art in R16 or R17 release.
Disclosure of Invention
In the NTN network, User Equipment (UE) and a satellite or an aircraft communicate through a 5G network, and since the distance from the satellite or the aircraft to the User Equipment is far greater than the distance from a ground base station to the User Equipment, a long transmission Delay (Propagation Delay) is caused during communication transmission between the satellite or the aircraft and the User Equipment. In addition, when the satellite is used as a relay device for the ground station, the delay of the Feeder Link (Feeder Link) between the satellite and the ground station may further increase the transmission delay between the user equipment and the base station. On the other hand, since the coverage of satellites and aircraft is much larger than that of Terrestrial Networks (Terrestrial Networks), while the difference between delays in NTN is very large due to the different inclination of the Terrestrial devices to the satellites or aircraft. In the existing LTE (Long Term Evolution) or 5G NR system, the maximum delay difference is only a few microseconds or a few tens of microseconds, but the maximum delay difference in NTN may reach several milliseconds or even a few tens of milliseconds. Since the existing random access in LTE or NR is designed for the conventional terrestrial communication and cannot be directly applied to the NTN network, a new design is required to support the network with large delay difference, especially the NTN communication.
The application provides a solution to the problem of random access in large delay difference networks, especially NTN communication.

The controller/processor can be associated with a memory 480 that stores program codes and data. Memory 480 may be referred to as a computer-readable medium.
In an Uplink (UL) transmission, a data source/buffer 480 is used to provide higher layer data to controller/processor 490. The data source/buffer 480 represents all protocol layers above the L2 layer and the L2 layer. The controller/processor 490 implements the L2 layer protocol for the user plane and the control plane by providing header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the second communication node 410. The controller/processor 490 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the second communication node 410. The first signal in this application is generated at the data source/buffer 480 or at the controller/processor 490. The transmit processor 455 implements various signal transmit processing functions for the L1 layer (i.e., the physical layer), where the physical layer signal of the first signal in this application is generated at the transmit processor 455. The signal transmission processing functions include coding and interleaving to facilitate Forward Error Correction (FEC) at the UE450 and modulation of the baseband signal based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)), splitting the modulation symbols into parallel streams and mapping each stream to a respective multi-carrier subcarrier and/or multi-carrier symbol, which are then mapped by the transmit processor 455 to the antenna 460 via the transmitter 456 for transmission as a radio frequency signal. Receivers 416 receive radio frequency signals through their respective antennas 420, each receiver 416 recovers baseband information modulated onto a radio frequency carrier, and provides the baseband information to receive processor 412. The receive processor 412 implements various signal reception processing functions for the L1 layer (i.e., the physical layer), including receiving a physical layer signal that processes the first signal in this application, including obtaining a stream of multicarrier symbols, then demodulating the multicarrier symbols in the stream of multicarrier symbols based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)), then decoding and deinterleaving to recover the data and/or control signals originally transmitted by the first communication node device 450 on the physical channel. The data and/or control signals are then provided to a controller/processor 440. The functions of the L2 layer, including the interpretation of the information carried by the first signal in this application, are performed at the controller/processor 440. The controller/processor can be associated with a buffer 430 that stores program codes and data. The buffer 430 may be a computer-readable medium.
