US Patent 10560139 Dynamic control of single switched uplink versus multi uplink

Apparatus and methods for dynamic control of single switched uplink versus multi uplink are provided. In certain embodiments, a mobile device includes a front end system including a first transmit chain and a second transmit chain. The mobile device further includes a transceiver that transmits a first type of RF signal and a second type of RF signal by way of the front end system. The transceiver is operable in a first mode in which transmissions of the first type of RF signal and the second type of RF signal are staggered, and a second mode in which transmissions of the first type of RF signal and the second type of RF signal at least partially overlap in time. The transceiver includes a transmit control circuit that operates the transceiver in the first mode or the second mode based on comparing a transmit parameter to a threshold.
