Abstract: A first relay node in a wireless communication system receives, from a second relay node via a backhaul link, coordination information including an index indicating a density pattern of a second phase tracking reference signal (PTRS). The first relay node transmits, to a terminal, configuration information including information on a first subcarrier offset for a first PTRS. The first relay node transmits to the terminal the first PTRS based on the coordination information and the information on the first subcarrier offset. The first subcarrier offset for the first PTRS is different from a second subcarrier offset for the second PTRS.

Abstract: Disclosed is a method of configuring a Positioning Reference Signal, PRS, in each of a plurality of cells in a telecommunication network. The method of a serving base station (BS) may include transmitting a second positioning reference signal (PRS) to a user equipment (UE); receiving, from the UE, a request to request a neighbor BS to configure a first PRS to occupy (1/μ)th of slot duration of a Sub Carrier Spacing (SCS) of the neighbor BS; and transmitting the request to the neighbor BS, wherein the neighbor BS having a lower (SCS) than an SCS of the serving BS, and wherein μ is the ratio of the SCS of the serving BS to the SCS of the neighbor BS.

Abstract: Provided are methods and apparatuses for performing a random access of a terminal in a wireless communication system. A method, performed by a terminal, of performing a random access, according to an embodiment, includes receiving preamble configuration information from a base station, obtaining a RACH (random access channel) preamble scaled in length in proportion to a difference between an expected minimum distance and an expected maximum distance to the base station from opposed edges of a cell served by the base station, based on the preamble configuration information and transmitting the obtained RACH preamble to the base station to access a NTN (non-terrestrial network).
