Abstract:
Techniques are disclosed for handover of a user equipment (UE) from a serving base station to a target base station. A target base station may use one or more directional beams to establish wireless communication links with UEs within a coverage area of the target base station. Directional beams may create a narrow-beam, high-bandwidth connection with a UE in a limited geographic area. Handover procedures include some latency between when a target base station dedicates resources to a UE and when the UE executes a communication via those dedicated resources. To compensate for latencies in a handover procedure and for the geographic limitations of directional beams, a target base station may assign multiple directional beams to the UE during a handover procedure. Each directional beam may be associated with access parameters used by the UE to generate messages (e.g., a RACH message) during the handover procedure.
