Handover schemes for millimeter wave (mmw) wireless communications

A method for wireless communications, comprising:

• establishing, at a first base station, a first connection with a millimeter wave (mmW) user equipment (UE);
• receiving, from the mmW UE, a handover message that comprises a handover configuration for a second base station, the handover configuration identifying a beam associated with the second base station and a handover time by which the mmW UE intends to attempt to communicate with the second base station via the beam;
• transmitting, based at least in part on the handover message, an indication of the handover configuration to the second base station;
• and
• performing handover of the mmW UE from the first base station to the second base station based at least in part on the handover configuration.

A method for wireless communications, comprising:

• receiving, at a second base station and from a first base station, a handover configuration for a millimeter wave (mmW) user equipment (UE), the handover configuration identifying a beam associated with the second base station and a handover time by which the mmW UE intends to attempt to communicate with the second base station via the beam;
• determining a connection configuration for the mmW UE based at least in part on the handover configuration, the connection configuration including an allocation of resources to be used by the mmW UE for handover to the second base station;
• and
• performing handover of the mmW UE from the first base station to the second base station based at least in part on the connection configuration.

An apparatus for wireless communications, comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• establish, by a millimeter wave (mmW) user equipment (UE), a first connection with a first base station;
• determine, by the mmW UE, to perform handover from the first base station to a second base station;
• transmit, based at least in part on the determination to perform handover, a handover message comprising a handover configuration identifying a beam associated with the second base station and a handover time by which the mmW UE intends to attempt to communicate with the second base station via the beam;
• and
• establish, by the mmW UE, a second connection with the second base station in accordance with the handover configuration.
