    Abstract: An example electronic device includes a first housing including, a first display, a first antenna, a second antenna, and a first rotational motion sensor. The electronic device also includes a hinge including a bend sensor. The electronic device further includes a second housing rotatable coupled to the first housing via the hinge. The second housing includes a second display, a third antenna, a fourth antenna, and a second rotational motion sensor. The electronic device further includes a communication device to select two of the first antenna, the second antenna, the third antenna, and the fourth antenna based on the first rotational motion sensor, the second rotational motion sensor, and the bend sensor. The communication device is also to transmit and receive data via each of the two selected antennas.

    Abstract: Facilitating a determination of channel state information for advanced networks (e.g., 4G, 5G, and beyond) is provided herein. Operations of a system can comprise configuring a mobile device with a demodulation reference signal. The operations can also comprise transmitting a channel state information reference signal to the mobile device, wherein the channel state information reference signal configures a number of channel state information reference signal ports. Operations of another system can comprise determining a number of resources for a group of transmission ranks and determining a link quality metric for transmission ranks of the group of transmission ranks. The operations can also comprise selecting a transmission rank and a precoding matrix indicator and transmitting the precoding matrix indicator to a network device.

    Abstract: Systems, methods, and software technology for partitioning media streams is disclosed herein. In an implementation, an application partitions an encoded media stream into multiple sub-streams having different code rates relative to each other. The sub-streams may then be transmitted to different wireless access points. A change in a monitored performance of at least one of the wireless access points may drive a modification to the partitioning of the media stream such that the code rates change relative to each other.

    Abstract: In a device including a processor and memory in communication with the processor, the memory includes executable instructions that, when executed by the processor, cause the device to perform functions of determining that the device has available bandwidth to receive at least a portion of a first data stream sent from a first remote device to a second remote device on a wireless channel, wherein the data stream is addressed to a third remote device; receiving a part, or the entirety, of the first data stream; generating a second data stream from the received part or entirety of the first data stream, wherein the second data stream is shorter than the first data stream sent from the first remote device; and sending the second data stream to the third remote device. The second data stream is used at the third device to improve QoS related parameters such as a bit error rate (BER), a packet error rate (PER), and/or data rate for the first data stream sent from the first device.
