Abstract: When a failed connection is detected from a first radio unit (RU) to the cellular site router (CSR), activation of an existing backup cabled connection from the first RU to the CSR through a cabled connection between the first RU and a second RU of the cellular telecommunications tower may be performed. In one example, a first RU and second RU each have two physical network ports. The activation of the existing backup cabled connection from the first RU, via the second RU, to the CSR may include causing the first RU to enter from a normal operating mode into an Open Radio Access Network (O-RAN) cascade operating mode to attempt to attain network connectivity for the first RU using the second physical network port of the first RU.

Abstract: Systems and methods are provided for adaptive bandwidth (BW) management configuring an element management control unit including a set of distribution/central units (DU/CU) for monitoring power and traffic loads at a plurality of cell sites in a network; communicating with a BW management unit coupled to the element management system to adapt BW for users at cell sites by moving users to a set of smaller bandwidth parts (BWPs) at a cell site in response to a set of conditions of AC power outages and reduced traffic loads detected by the BW management unit, and in response to at least one of the detected conditions, instructing based on data from the DU/CU to the BW management unit to move user traffic to a designated lower BWP of the set of smaller BWPs at the cell site while shutting down other BWPs at the cell site to save the power of an operating cell site.

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: A method for performing a software update that reduces down time in a Radio Access Network (RAN) is disclosed. A first computing device receives first Distributed Unit (DU) configuration information including an address of a first radio unit (RU) device. The first computing device cause the first RU device to stores an address of the first computing device as a value of a configuration parameter. After a second computing device installs software, the second computing device receives the first DU configuration information including the address of the first RU device. The first computing device receives an instruction to stop data transmission to the first RU device. The second computing device causes the first RU device stores an address of the second computing device as the value of the configuration parameter. The second computing device receives an instruction to start data transmission to the first RU 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 network nodes; 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.

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.

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.
