Abstract:
1. A mobile device comprising a source radio and a target radio: at least one transmitter of the source radio used to wirelessly transmit signals to at least one network; and at least one receiver used to wirelessly receive signals from the at least one network, wherein the source radio and the target radios are configured to wirelessly communicate with a first network and a second network, respectively, wherein the target radio is configured to communicate with the second network during a handover procedure from the first network to the second network without disconnecting a link between the mobile device and the first network, wherein the mobile device is configured to communicate with the second network during transmitting and receiving opportunities in the handover procedure, and wherein the link between the mobile device and the first network remains at least partially active during the transmitting and receiving opportunities between the mobile device and the second network such that the mobile device having a single transmission power amplifier shared between the source and the target radio to accommodate required high switching speed may repeatedly alternate between communicating with the first network outside the transmitting and receiving opportunities and the second network during the transmitting and receiving opportunities; wherein the transmitting and receiving opportunities comprise communication gaps between the mobile device and the first network; and in the transmitting opportunities, a first receiver receives signals from a first network but the first transmitter does not transmit signals to the first network.
