We propose a novel approach to Unsourced Random Access (URA) in which the encoding of each user's message is associated with the user's location. The presented reception algorithm is able to resolve message collisions and enhance the multiple user detection via estimation of the angles-of-arrival (AoA) of the users' signals. We demonstrate that the proposed technique allows to nearly double the number of supported active users in comparison to the state-of-the-art and reduces the required system's signal-tonoise ratio (SNR).INDEX TERMS multiple-input multiple-output (MIMO), unsourced random access (URA), location, angleof-arrival (AoA)
