    Abstract: The disclosed technology is directed towards dynamic spread spectrum (DSS) deployments, in which two cells such as an LTE cell and a new radio (NR) cell share available physical resource blocks during a given transmission time interval. The LTE cell and NR cell determine priority values for their user equipments to be scheduled, and both cells provide requested scheduling information including the priority values and requested resource blocks for user equipments in the upcoming transmission time interval. Based on the priority values, a real-time joint scheduler processes the combined scheduling information from both cells to determine how many physical resource blocks of the total available to allocate to the LTE cell and how many to allocate to the NR cell for the next transmission time interval. To avoid collisions, the LTE cell and NR cell modify their respective UE schedules based on their respective number of allocated physical resource blocks.

    Abstract: The described technology is generally directed towards wireless communications for vehicle collision response. Devices onboard vehicles can wirelessly exchange information in response to detecting a collision. Public encryption keys can be exchanged, and exchanged information can optionally be encrypted using a received public encryption key. Exchanged information can include vehicle identification information and collision information. The collision information can furthermore be certified using a vehicle's private encryption key.

    Abstract: The technologies described herein are generally directed to modeling radio wave propagation in a fifth generation (5G) network or other next generation networks. For example, a method described herein can include, for a network application, identifying, by a system comprising a processor, a first performance characteristic of first base station equipment, wherein the first base station equipment is actively communicating with a user equipment via a first network connection. The method can further include, based on the first performance characteristic being in a condition in relation to a first threshold, determining, by the system, to execute a handover of the user equipment to a second network connection with second base station equipment, resulting in a handover determination. Further, the method can include, based on the handover determination, facilitating, by the system, executing the handover of the user equipment to the second network connection.
