Seamless mobility for wireless devices

Abstract

User equipment may include a transmitter and a receiver coupled to an antenna to enable the user equipment to transmit and receive user data with a base station of the wireless network. However, the user equipment may perform power-consuming searches to determine a base station for connection. Furthermore, the connection may be affected by blockages and transitions during mobility scenarios. As such, it may be beneficial for the user equipment to implement mobility procedures. For example, the user equipment may form links with multiple base stations of a cell cluster for transitioning. In another example, the wireless network may generate a map with locations of base stations and beam characteristics for the user equipment to determine coverage areas and decrease a number of transitions. Still in another example, the user equipment may receive blockage information to predict a blockage and implement mobility procedures to maintain wireless service during a blockage.
