Title:
RANDOM ACCESS PREAMBLE TRANSMISSION AND RECEPTION IN NON-TERRESTRIAL NETWORK COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2021/115367
Kind Code:
A1
Abstract:
The present disclosure proposes schemes, techniques, designs and methods pertaining to transmission and reception of random access preambles to aid integration of terrestrial mobile network communication and non-terrestrial network (NTN) communication. The design of a proposed preamble is suitable for terrestrial mobile networks and for transmission scenarios with Doppler frequency shift and long propagation delay in NTN communications. The structure of the proposed preamble is used in random access of terrestrial and NTNs. The structure of the preamble can be modified based on the preamble design used for terrestrial network communication, so that it can be used in the random access of NTNs.
