1. A method for wireless communication, comprising:

  • transmitting a first uplink signal by a user equipment (UE) to a first virtualized radio unit;

    transmitting a second uplink signal by the UE to a second virtualized radio unit,wherein the first and second uplink signals are processed by one or more virtual machines shared by both the first and second radio units, andwherein a first virtual machine implements at least one of a lower physical layer (PHY-Low), an analog-to-digital converter (ADC), a digital-to-analog converter (DAC), and a radio frequency (RF) transceiver, andwherein a second virtual machine implements at least one of a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a higher physical (PHY-high) layermaintaining connection by the UE with the first virtual radio unit during a first time interval; and

    switching connection by the UE during a second time interval from the first virtual radio unit to the second virtual radio unit.
