Abstract: A telecommunication network associated with a wireless telecommunication provider can be configured to switch between New Radio (NR) Dual Connectivity (DC) and NR Carrier Aggregation (CA) in 5G cellular networks. According to examples, a UE is not limited to using a single mode (e.g., either NR CA or NR DC) that is initially selected for use by the UE. For example, a UE can be reconfigured during a session to switch from NR DC to NR CA when the UE moves toward mid-cell and/or a cell edge. In other examples, the UE can be reconfigured to switch from NR CA to NR DC when the UE moves closer to the cell. To determine when to switch, one or more network conditions (e.g., UE RF conditions) can be monitored. In some examples, a gNB can monitor power headroom reports (PHRs) received from the UE to determine when to switch.

Abstract: Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to perform power-boosting to increase power for specific portions (e.g., repetitions, symbols, slots) of an uplink transmission, where the portion may overlap with a previously-scheduled uplink transmission from another UE. The base station may configure the UE to apply power-boosting to all portions of the uplink transmission or over specific slots or repetitions of the uplink transmission, or to apply power-boosting if the uplink transmission occupies one slot or repetition. The base station may configure the UE semi-statically or dynamically with the power-boosting configuration, and may configure the UE to perform power-boosting for repetitions of the uplink transmission corresponding to one or more predefined transmission reception points, panels, beams, or precoders. The UE may transmit the uplink transmission to the base station based on the power-boosting configuration.

For example, selected stations may be triggered to communicate with respective access points.

Abstract: The present invention is provides a method and apparatus for routing a data packet in a network. For each nearby device capable of routing the packet toward a further destination, an associated cost or utility is determined. The device with lowest cost or highest utility is selected and the packet is forwarded toward same. The selecting may use a comparator tree. The cost or utility may be associated with forwarding the data packet from the candidate device toward the further destination. The cost or utility may be based on a distance from candidate device to the further destination, and may be determined using a Haversine function or approximation thereof, or by computing an inner product of a first vector and a second vector originating at a center of Earth, the first vector directed toward the candidate device, the second vector directed toward the further destination.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support signaling an indication of a duration (for example, in UE capability information) for the UE to perform a beam switch (for example, to switch between different directional beams). Among other examples, base stations may be configured with a default value related to a duration for UEs to perform a beam switch. Thus, in an absence of the above signaling by the UE, base stations may identify a duration for UEs to perform a beam switch according to the configured default value. Additionally, base stations may allocate symbols between different physical channels (such as, downlink channels or uplink channels) related to directional communications. One or more symbols may be exclusive of or be part of resources related to the physical channels to provide improvements to beam switching for UEs.
