Description
The application is a divisional application of the following original application:
filing date of the original application: 2019, 06, 19 days
Number of the original application: 201910531097.1
-The name of the invention of the original application: method and apparatus in a communication node for wireless communication
Technical Field
The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus with a large delay difference.
Background
Future wireless communication systems have more and more diversified application scenes, and different application scenes have different performance requirements on the system. To meet different performance requirements of various application scenarios, research on a new air interface technology (NR, new radio) (or 5G) is decided at the 3GPP (3 rd Generation Partner Project, third generation partnership project) RAN (Radio Access Network ) #72 full-time, and standardization work on NR is started at the 3GPP RAN #75 full-time WI (work item) that passes the new air interface technology (NR, new radio).
In order to be able to adapt to various application scenarios and meet different requirements, a Non-terrestrial network under NR (NTN, non-TERRESTRIAL NETWORKS) study was also passed on the 3gpp ran #75 meeting, which starts in R15 version. The decision to start to study solutions in NTN networks is made at 3gpp ran#79 full meeting, then WI is started in R16 or R17 version to standardize the related technology.
Disclosure of Invention
In NTN networks, a User Equipment (UE) and a satellite or an aircraft communicate via a 5G network, which results in a long transmission delay (Propagation Delay) when the satellite or the aircraft is in communication with the user equipment because the satellite or the aircraft reaches the user equipment far farther than the ground base station. In addition, when the satellite is used as a relay device for the ground station, the delay of the spur link (FEEDER LINK) between the satellite and the ground station may further increase the transmission delay between the user device and the base station. On the other hand, due to the much larger coverage of the satellite and aircraft compared to the ground network (TERRESTRIAL NETWORKS), and due to the different tilt angles of the ground equipment to the satellite or aircraft, the difference between the delays in the NTN is very large. In existing LTE (Long Term Evolution ) or 5G NR systems, the maximum delay difference is only a few microseconds or tens of microseconds, but in NTN the maximum delay difference can reach a few milliseconds or even tens of milliseconds. Since the random access in the existing 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 large delay difference network, especially the NTN communication.
The present application provides a solution to the problem in random access in large delay-difference networks, especially NTN communications. It should be noted that embodiments of the base station apparatus and features of the embodiments of the present application may be applied to the user equipment and vice versa without conflict.

Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY301.
