Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long TermEvolution (LTE). Disclosed is a method of configuring PTRS transmissions in a telecommunication network employing Integrated Access and Backhaul, the method comprising the steps of transmitting PTRSon a first subcarrier in a first cell, transmitting PTRS on a second subcarrier, different to the first subcarrier, in a second cell, neighbouring the first cell and configuring the PTRS transmissionsubcarrier according to a predefined base pattern and an index term, whereby the index term is communicated between the first and second cells for coordination purposes.

Description

technical field [0001] The present disclosure relates to a telecommunications network employing an integrated access and backhaul (IAB) and / or a non-terrestrial network (NTN). Background technique [0002] In order to meet the increasing demand for wireless data services since the deployment of fourth generation (4G) communication systems, efforts have been made to develop improved fifth generation (5G) or pre-5G (pre-5G) communication systems. Therefore, the 5G or pre-5G communication system is also called "super 4G network" or "post-Long Term Evolution (LTE) system". [0003] 5G communication systems are considered to be implemented in higher frequency (mmWave) frequency bands (eg, 28GHz or 60GHz frequency bands) in order to achieve higher data rates. In order to reduce the propagation loss of radio waves and increase the transmission distance, beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, ...
