SYSTEM FOR WIRELESS COMMUNICATION WITH RADAR SENSING, CORRESPONDING METHOD AND DEVICE Interuniversitair Micro-Electronica Centrum vzw
We address the problem of mutual interference in simultaneous communications and sensing (radar) in a cell-free massive MIMO system. We propose to perform simultaneous communications and sensing during the uplink part of a frame consisting for three phases: training phase, uplink and downlink, as illustrated in Fig. 2. The network allocates, in the same time-frequency resources as the user equipment’s (UEs), a set of access-points (Tx APs) to participate in the uplink to serve the network with known radar signals. The remaining APs (Rx APs) receive a sum of communication and radar signals and ...
