Abstract: A wireless device may comprise antennas and a processor configured to cause the wireless device to determine preferred antenna ports for at least one primary component carriers (PCCs) and at least one secondary component carriers (SCCs) based on performed downlink measurements of antenna ports. The wireless device may further determine support capabilities of the wireless device and perform computations using additional measurements of the antenna ports. Based on the computations, the wireless device may assign the preferred antenna ports to the PCCs and SCCs and perform uplink transmission using the assigned antenna ports.

Abstract: Systems and methods described herein may enable user equipment to confirm and/or change a multiple input, multiple output (MIMO) communication configuration selected by a network, such as to change a number of data layers used in the MIMO communication and/or to change one or more antennas used in the MIMO communication. The user equipment may confirm and/or change the MIMO communication configuration based on transmit power levels associated with the one or more antennas, a distance between power amplifiers and respective antennas, or the like, as described herein.

Abstract: The present disclosure relates to opportunistically selecting an antenna in an electronic device having multiple antennas. A baseband processor of the electronic device may connect to a first cellular tower providing cellular service at a first frequency using a first antenna of the electronic device. The baseband processor may then receive an indication of a handover event to a second cellular tower operating at a second frequency. The baseband processor may determine signal measurements of the second cellular tower for each antenna of the electronic device that is capable of operating at the second frequency. The baseband processor may execute a handover to the second cellular tower using the antenna associated with the best performing signal measurements. In this manner, an antenna may be opportunistically selected based on performance of the antenna, improving operation of the electronic device and quality of cellular service.

Abstract: A wireless communication device (UE) may conduct wireless communications using one or more antennas according to multiple radio access technologies (RAT) associated with corresponding operating frequency bands. The UE may perform adaptive antenna tuning, for example, application-based antenna tuning for increasing the operating efficiency of the UE, which may improve user experience. The UE may periodically identify one or more applications running on the UE, the respective RATs that support the (running) applications, and which of the corresponding frequency bands are used by the (running) applications. The UE may determine the tuner device settings for tuning the one or more antenna(s) based on the (running) applications or the type and/or priority of the (running) applications, which RATs support the running applications, which of the corresponding frequency bands are used by the (running) applications, and operating conditions associated with the frequency bands used by the (running) applications.
