Title: UE CAPABILITY SIGNALING FOR MAKE-BEFORE-BREAK AND RACH-LESS HANDOVER
Abstract:
A User Equipment (UE) may transmit handover capability information to a cellular network. The UE may signal the cellular network (i.e., transmit the handover capability information to the network) when the UE supports RACH-less and/or make-before-break handover operations. The signaling, by the UE, may be performed when the UE initially accesses the network, such as via a UE Capability Information message. The handover capability information may be transferred between base stations as part of a UE handover operation. The cellular network, such as a particular base station in the cellular network, may subsequently implement handover operations based on the indicated capabilities that are supported by the UE.
