摘要： Embodiments herein relate to a method in a radio base station (12) for estimating a noise floor in a cell (15) of a radio communications network. The radio base station (12) is comprised in the radio communications network and serves the cell (15) in the radio communications network. The radio base station (12) determines a time interval in which time interval the noise floor in the cell (15) is to be estimated. The radio base station further reduces a first interference during the determined time interval in the cell (15) and then measures a second interference in the cell (15) at a time in the time interval in the cell 15. The radio base station then estimates the noise floor using the measured second interference.

摘要： The present disclosure relates to a method for allocating Time Transmission Intervals, TTI, during Up Link, UL, transmissions in a shared radio cell environment. The present disclosure also relates to a network node for performing said allocation method. The allocation is performed by determining for each network node (10; 20A; 20B; 20C) in the shared radio cell environment which UEs (30) it serves and listens to. The TTIs are the allocated such that the UE transmission for UEs related to a network node (10; 20A; 20B; 20C) is coordinated by scheduling said UE transmission in the same TTI frame for a serving network node (10; 20A; 20B; 20C) and for one or more of listening network nodes (10; 20A; 20B; 20C) in the shared radio cell environment.
