Abstract: A parent node in a wireless communication network is arranged to communicate backhaul traffic wirelessly with an Integrated Access Backhaul (IAB) node. The parent node may determine time resources for a distributed unit (DU) of the IAB node to communicate backhaul traffic with a child node or a mobile terminal, and transmit an indication of the determined time resources to the IAB node. The parent node may also determine time resources for a mobile termination (MT) of the IAB node to communicate backhaul traffic with the parent node, and transmit an indication of the determined time resources to the IAB node. The IAB may receive, from the parent node, at least one indication of time resources for communicating backhaul data with the parent node, and communicate backhaul data with the parent node based on the time resources. The IAB node may also receive, from the parent node, at least one indication of time resources for communicating backhaul data with the child node or the mobile terminal, and communicate backhaul data with the child node or the mobile terminal based on the time resources.

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 Term Evolution (LTE). Described is a method for providing a Phase Tracking Reference Signal (PTRS) in a wireless communication system. The method comprises transmitting, by a base station to a plurality of mobile devices, the PTRS in a wide beam transmission at a first power level. The first power level is set such that at least some of the mobile devices receive the PTRS with a sufficiently high signal strength to enable the PTRS to be correctly received and such that at least some of the mobile devices receive the PTRS with a sufficiently low signal strength to enable the PTRS to be processed as manageable interference. A first mobile device may estimate the Signal to Interference plus Noise Ratio (SINR) of the received PTRS, and transmit, to the base station, feedback information based on the estimated SINR. The base station may transmit, to the first mobile device, a narrow beam transmission comprising one or more allocated Resource Elements (REs) configured according to the feedback information. The allocated REs may be configured to (i) be left empty, so as to carry no information, (ii) contain data, or (iii) contain PTRS.
