Abstract: Various arrangements for updating a radio unit (RU) of a cellular network are presented. A volume of cellular signals being handled by a first programmable processor of the RU and a second programmable processor of the RU may be analyzed. A determination can be made that one of the processors has sufficient available resources to handle the analyzed volume of cellular signals. The RU can cause cellular signals to be rerouted to one of the programmable processors while the other processor is taken offline for updating. The update process is performed such that UE in communication with the RU experience uninterrupted cellular network access.

Abstract: Automated processes, computing systems, devices and other aspects of a wireless data network are described. According to various embodiments, message flooding in the wireless network is reduced through the use of "dummy" messages from the radio unit (RU) to the distributed unit (DU) and/or layer two (L2) switch. The dummy messages prevent timeout of the RU's data in the L2 switch's routing tables, thereby prolonging the period of time that the L2 switch is able to more efficiently direct subsequent traffic toward that particular device.

Abstract: Systems and methods of adaptive bandwidth (BW) management are provided by a control unit of distribution and central units to monitor power and traffic loads at a plurality of nodes in a network; a BW management unit communicating with the control unit to reassign a set of network slices with a set of smaller bandwidth parts (BWPs); the BW management unit configured to define a smaller BWP from a slice mapping for the slice reassignment during a AC power outage, the slicing mapping includes network slices tied to smaller BWPs in the network; and the BW management unit configured to adapt BW for users at the node by reassigning of at least one network slice with a defined smaller BWP at the node in response to a condition determined by the BW management unit, the condition of at least one of a AC power outage, and reduced traffic load at the node.

Abstract: Various arrangements for transitioning the bandwidth allocation of a base station are presented. Four bandwidth parts may be defined for communication with the base station. At a given time, two of these bandwidth parts may be actively used for communication by different UE for communication with the base station. In response to network traffic, a determination to adjust a bandwidth allocation may be made. A series of transitions may be performed to migrate from the first two of these bandwidth parts to the second two of the bandwidth parts such that interference does not occur.

Abstract: Various arrangements for improving cell coverage are presented. A cellular network can define a first bandwidth part and a second bandwidth part to be implemented concurrently by a base station of the cellular network. The first bandwidth part and the second bandwidth part do not overlap and may be separated by a guard band. The first bandwidth part can have a greater bandwidth and greater sub-carrier spacing than the second bandwidth part. The cellular network can determine a first set of user equipment to use the first bandwidth part for communication with the base station and a second set of user equipment to use the second bandwidth part for communication with the base station. Communication with the first set of user equipment using the first bandwidth part and the second set of user equipment using the second bandwidth part may be performed.

Abstract: A new radio base station establishes a first and a second component carrier in carrier aggregation. The first and second component carrier overlap each other. The base station transmits signaling and control information exclusively on the first component carrier. The base station transmits data packets on the first component carrier and on a non-overlapping portion of the second component carrier.
