1. A method of handover in wireless communications comprising:
receiving, by a first user equipment (UE) from a first base station, one or more first messages comprising:
measurement configuration parameters; and
first configuration parameters comprising sidelink parameters, the first configuration parameters associated with a first cell;
establishing, by the first UE, a sidelink with a second UE based on the sidelink parameters;
transmitting, by the first UE to the first base station, a measurement report based on the measurement configuration parameters;
responsive to the transmitted measurement report, receiving, by the first UE from the first base station, a second message comprising second configuration parameters of a second cell of a second base station, wherein the second configuration parameters do not comprise sidelink parameters; and
switching, from the first cell of the first base station to the second cell of the second base station, wherein the sidelink of the first cell is handed over to an uplink of the second cell.
 
30. A method of handover in wireless communications comprising:
receiving, by a first user equipment (UE) from a first base station, one or more first messages comprising:
measurement configuration parameters; and
first configuration parameters, of a first cell, not comprising sidelink parameters;
transmitting, by the first UE to the first base station, a measurement report based on the measurement configuration parameters;
responsive to the transmitted measurement report, receiving, by the first UE from the first base station, a second message comprising second configuration parameters of a second cell of a second base station, wherein the second configuration parameters comprise sidelink parameters; and
switching, from the first cell of the first base station to the second cell of the second base station, wherein an uplink of the first cell is handed over to the sidelink of the second cell.
