Abstract: The present disclosure relates to a method and audio processing system for performing dynamic range adjustment of spatial audio objects. The method comprises obtaining (step S1) a plurality of spatial audio objects (10), obtaining (step S2) at least one rendered audio presentation of the spatial audio objects (10) and determining (step S3) signal level data associated with each presentation audio channel in said set of presentation audio channels. The method further comprises obtaining (step S31) a threshold value and, for each time segment, selecting (step S4) a selected presentation audio channel which is associated with a highest or a lowest signal level, determining (step S5) a gain based on the threshold value and the representation of the signal level of the selected audio channel, and applying (step S6) the gain of each time segment to corresponding time segments of the spatial audio objects.

Abstract: A system for testing a radio transmitter includes multiple unmanned aerial vehicles (UAVs). The multiple UAVs are deployed in the environment surrounding the radio transmitter, enabling simultaneous measurement of the signal emitted by the radio transmitter at multiple points in a variety of configurations. In some implementations, one of the UAVs can be configured as a control unit that facilitates communication between the radio transmitter and the remaining UAVs. In this manner, measurements can be transmitted from the UAVs to the transmitter in real-time. These measurements can then be used as feedback to quickly adjust the radio transmission or reception or to update the flight pattern of the UAVs.

Abstract: A system uses pulsed lasers to enhance a signal propagation path in a telecommunications network. The system can estimate a signal propagation path, which varies based on a current location of a mobile device relative to a base station. The system can detect a propagation loss due to a condition of a propagation medium including the signal propagation path and determine whether the mobile device is in Line-of-Sight (LOS) of a laser emitter. In response to detection of the propagation loss, the laser emitter can emit a pulsed laser that can enhance signal propagation by mitigating the propagation loss on the signal propagation path. The pulsed laser has a propagation path overlapping the signal propagation path when the mobile device is in LOS of the laser emitter, which is mounted on the base station.

Abstract: The disclosed technology includes a technique for securing communications over a wireless telecommunications network. Quantum entangled particles are generated and optically communicated to a wireless endpoint device (e.g., smartphone) within Line-of-Sight (LOS) of the particle generator and optionally to a network access node (e.g., base station). A particle generator can be positioned on a communications tower, mountain, tall building, or other structure that enables greater LOS to multiple endpoint devices and network access nodes. The quantum states of entangled particles are used to generate counterpart cryptographic keys at the wireless endpoint device and network access node. As such, the counterpart keys can secure communications while underlying particles remain quantumly entangled.

Abstract: Solutions for physical uplink control channel (PUCCH) allocation, for example on a 5G network, include receiving, at a base station (BS) on a network, a session request message from a user equipment (UE) requesting a network session; based on at least receiving the session request message, determining a channel quality of a channel between the UE and the BS; based on at least the channel quality, selecting a first PUCCH format; and transmitting a message, from the BS, to the UE, instructing the UE to configure the PUCCH according to the first selected PUCCH format. Some examples further include: monitoring for a format change trigger; based on at least detecting the format change trigger, selecting a second PUCCH format different than the first PUCCH format; and transmitting a message, from the BS, to the UE, instructing the UE to configure the PUCCH according to the second selected PUCCH format.

Abstract: A method and system is disclosed for dynamic swapping of uplink and downlink base stations. A user equipment device (UE) may engage in a communication session with a downlink from a first base station (e.g., eNodeB) and an uplink to second, different base station. If a determination is made that more favorable operating conditions for transmitting session communications to the UE are available on a downlink air interface from the second base station than on the downlink air interface from the first base station, the uplink and downlink may be swapped, such that after swapping, the UE may have a downlink from second base station and an uplink to the first base station.

Abstract: In systems and methods of selecting an access node for wireless device communication, it is determined that a first loading of a first access node meets a first loading criteria, and a wireless device is selected which is in communication with the first access node and which detects a second access node. A request is sent to the second access node to accept a handover of the wireless device, and a timer is started comprising a first timer value when the request is rejected by the second access node. A second request is sent to the second access node to accept a handover of the wireless device to the second access node when the timer expires, and the wireless device is instructed to change from communicating with the first access node to communicating with the second access node when the second request is accepted by the second access node.

Abstract: A method, system, and medium are provided for increasing carrier-to-interference-and-noise ratio (CINR) gain in a long-term-evolution network deploying beam forming (BF) technologies. Adjacent eNodeBs, each serving a respective user equipment (UE) located at the boundary between the two eNodeBs, communicate BF parameters to each other. Each eNodeB uses the received BF parameters to adjust its DL transmission beam in order to decrease the interference at each of the respective UEs. By adjusting the DL transmission beam to decrease interference, CINR gain at the UEs is correspondingly increased.
