Techniques for communication protocol based on physical configuration of a wireless device are described and may be implemented to adapt to a variety of different wireless scenarios. For instance, configuration of an antenna system of a wireless device is adapted to optimize wireless performance in different physical configurations, such as open configurations and folded configurations. Further, network communications are adapted to optimize wireless communication with a wireless device in different physical configurations of the wireless device. The described techniques, for instance, optimize performance in different frequency bands based on changes in device configuration between open positions and folded positions.

Communication protocol based on physical configuration of a wireless device

Techniques for antenna configuration for a foldable device are described and may be implemented via a wireless device to adapt to a variety of different wireless scenarios. For instance, configuration of an antenna system of a wireless device is adapted to optimize wireless performance in different physical configurations, such as open configurations and folded configurations. Generally, the described techniques optimize performance in different frequency bands based on changes in device configuration between open positions and folded positions.

Antenna configuration for a foldable device

Techniques for antenna system with multiple transmit paths are described and may be implemented via a wireless device to adapt to a variety of different wireless scenarios. Generally, the described techniques provide a wireless device with the ability to connect to different access points of a wireless network, such as 4G LTE and 5G NR portions of an UTRAN New Radio&#x2014;Dual Connectivity (EN-DC)-compliant network. In at least some implementations, the described techniques utilize four-antenna systems configured to utilize low frequency bands, such as LTE low-band and 5G NR low-band frequencies. Further, the described systems enable multiple wireless protocols (e.g., LTE and 5G NR) to be used concurrently and cooperatively, such as to provide 5G NR connectivity utilizing an LTE network infrastructure.

Antenna system with multiple transmit paths

A communication device, method, and computer program product provide an antenna subsystem including a first antenna positioned proximate to a second antenna. A radio frequency (RF) frontend includes a transmitter, a receiver, and an antenna tuning module coupled to the antenna(s). A controller is communicatively coupled to the RF frontend and a memory containing a proximal antenna association tuning (PAAT) application. The controller executes the PAAT application to enable the communication device to: (i) transmit a reference signal by the transmitter using the first antenna of the more than one antenna; (ii) measure an impedance value of the first antenna based on the transmission of the reference signal; (iii) identify a second antenna of the more than one antenna that is proximate to the first antenna; and (iv) tune, via the antenna tuning module, the first and the second antenna based on the impedance value of the first antenna.
