    Abstract: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal to the base station, which characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. The base station may form the beam to the UE based on the uplink channel information obtained from the SRS. As the downlink channel changes the base station needs updated information to maintain its beamforming, meaning it needs a new SRS. Transmission of the SRS takes resources; to minimize this, the UE or the base station can determine a period during which the downlink channel will predictably remain coherent and set up a schedule for sending SRS. Alternatively, the UE or the base station can determine on demand that the channel is losing coherence and initiate an on demand SRS.

    Abstract: Wireless communication devices are adapted to facilitate non-orthogonal underlay transmissions. In one example, wireless communication devices can receive a wireless transmission via a particular time and frequency resource, where the wireless transmission includes a first signal employing a modulation associated with orthogonal wireless communication, and a second signal employing a modulation associated with non-orthogonal wireless communication. The wireless communication device can decode the first signal and the second signal. In another example, wireless communication devices may transmit a first signal utilizing a first type of modulation associated with non-orthogonal wireless communication, where the first signal is transmitted over at least a portion of a time and frequency resource scheduled for a second signal from a second wireless communication device, the second signal utilizing a second type of modulation associated with orthogonal wireless communication. Other aspects, embodiments, and features are also included.

    Abstract: One or more selectively activated features needed at a device to use a network service may be identified. Authorization information and feature activation key(s) associated with features that the device has been authorized to activate may be obtained at the device. The feature activation key(s) may be used to activate and/or maintain activation of the authorized features that match the selectively activated feature(s) needed to use the network service. An authorization server may obtain a request to activate one or more selectively activated features of a device. The authorization server may verify that the selectively activated feature(s) are authorized to be used at the device based on an authorization agreement obtained at the authorization server. The authorization server may send proof that the device is authorized to use the selectively activated feature(s) and may send feature activation key(s) based on the authorization agreement in response to the request.

    Abstract: Techniques are described for signaling a downlink bandwidth part (BWP) switching event and an aperiodic channel state information (A-CSI) request in a paired spectrum environment. The base station may transmit uplink scheduling downlink control information (DCI) to a user equipment (UE) that includes the A-CSI request and an identifier for the downlink BWP of the downlink BWP switching event. After receiving the A-CSI request and the downlink BWP, the UE may perform one or more CSI measurements using the downlink BWP. The UE may use physical uplink shared channel (PUSCH) resources associated with the uplink scheduling DCI to transmit the CSI report to the base station. Using these techniques, the base station may be configured to indicate that a downlink BWP switching event is to occur and allocate PUSCH resources to the UE to be used to transmit the CSI report associated with the downlink BWP switching event.
