Abstract: A first base station communicates with a UE via the first base station and a second base station. The first base station transmits, via a radio interface to the second base station, a configuration for concurrent communication between the UE and a group of base stations including the first base station and the second base station. The first base station communicates, by processing hardware, data over the radio interface directly with the UE, and via the radio interface and the second base stab on.

Abstract: Techniques and apparatuses are described for machine-learning architectures for broadcast and multicast communications. A network entity processes broadcast or multicast communications using a deep neural network (DNN) to direct the one or more broadcast or multicast communications to a targeted group of user equipments (UEs) using the wireless communication system.

Abstract: The systems, methods, and techniques described in this disclosure allow different wireless systems that operate in accordance with different Radio Access Technologies (RATs) to coexist within a same frequency domain with minimal (if any) inter-RAT interference. Specifically, the described techniques allocate a respective, mutually-exclusive portion of a plurality of Space-Time-Frequency (STF) resources for use in communicating in accordance with each different RAT. For example, mutually-exclusive portions of spatial domain resources, time domain resources, and/or frequency domain resources may be respectively allocated for exclusive use by different RATs. A centralized, third-party controller (120) may perform the allocations, or the allocations may be cooperatively arrived at between systems supporting different RATs, e.g., in a peer-to-peer manner. STF resource allocations may be static and/or dynamic over time, and STF resources may be uniquely identified by respective resource identifiers.

Abstract: A high-altitude platform (HAP) node provides communication service during an emergency. The HAP node uses a first network to provide communication services for handling calls initiated by at least one user equipment (UE). The HAP node detects that an emergency disruption has occurred that prevents the use of the first network.

The HAP node determines whether the second network will handle all calls initiated by the at least one UE or only emergency calls generated by the at least one UE. The HAP node handles the calls based on the determining and through the use of the second network.

Abstract: The techniques described in this disclosure enhance the reception of the information at a user equipment (UE) from an Active Coordination Set (ACS) of a wireless network system, where the ACS includes a set of base stations that jointly operate to communicate data between the system and the UE. The ACS allocates respective subsets of a plurality of time domain resources for use by corresponding ACS base stations in communicating with the UE, and provides, to the UE, an indication of the allocations. Based on the received allocation indication (502), the UE obtains data payload transmitted by the ACS (508) by tuning to various base stations in accordance with their respective time domain resource allocations (505). The ACS may redundantly transmit selected data payload and/or employ different encoding schemes to further enhance reception of information at the UE.
