In millimetre wave (mm-wave) communications, hybrid precoding is

preferred which uses much less number of RF chains compared with

the number of antenna elements. The conventional method selects the

beamforming vectors at base station (BS) and the combining vectors

at user equipments (UEs) to maximise the received signal power.

However, in some specific scenarios, when UEs have strong and

highly correlated paths, referred to as collided UEs, they might share

the same beamforming vector at the BS leading to severe inter-user

interference. An enhanced beam selection algorithm is proposed to eliminate

the severe inter-user interference by reselecting the beamforming/

combining vector pairs for the collided UEs. Simulation results demonstrate

that the proposed scheme could increase the achievable rates of the

collided UEs under sparse mm-wave wireless channels.
