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.

Wireless communications for vehicle collision response

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.

Using dynamic thresholds for non-mobility handovers in a fifth generation (5G) or other next generation network

Aspects of the subject disclosure may include, for example, a device including a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations of receiving signal to noise and interference ratio (SINR) measurements from a cell for two or more uplink carriers associated with a mobile device; determining an optimal uplink carrier from the two or more uplink carriers based on plural parameters, wherein the plural parameters include the SINR measurements; selecting the optimal uplink carrier from the two or more uplink carriers; and sending the optimal uplink carrier selected to the cell, wherein the mobile device uses the optimal uplink carrier for uplink transmissions. Other embodiments are disclosed.

Supplementary uplink carrier selection by radio access network intelligent controller

Aspects of the subject disclosure may include, for example, a process or apparatus for receiving, by a processing system including a processor, cell traffic reports for cells of a radio communication network, performing a reconfiguration analysis to identify reconfiguration information to reconfigure the radio communication network according to changing network conditions, and communicating the reconfiguration information defining a new cell configuration for the cells of the radio communication network and communicating information defining a new reconfiguration time for the cells to substantially synchronously switch to communicating according to the reconfiguration information. The receiving the cell traffic reports, the performing the reconfiguration analysis and the communicating the reconfiguration information occur in substantially real time. Other embodiments are disclosed.

Radio access network intelligent controller-based dynamic time division duplex communication in a radio communication network

The described technology is generally directed towards intelligent dual-connectivity for non-standalone network nodes. Network nodes can report state information to a central controller, such as a radio access network intelligent controller. The controller can determine, based on the state information reported by multiple network nodes, network nodes to cooperate in non-standalone mode. The controller can provide the network nodes with instructions to implement the controller's non-standalone relationship determinations.

Intelligent dual-connectivity in 5G non-standalone mode

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 user equipment communicatively coupled to base station equipment via a first network connection implementing a first radio access technology and a second network connection implementing a second radio access technology. The method can further include identifying, by the system, performance characteristics of the first network connection and the second network connection. Further, the method can include, based on the first performance characteristic and the second performance characteristic, facilitating, by the system, allocating, to the user equipment, power for uplink transmission by the first network connection and the second network connection, resulting in an uplink power allocation.

Allocating uplink power of user equipment between implementations of multiple radio access technologies in a fifth generation (5G) or other next generation network

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.
