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, methods, and devices dynamically allocate bandwidth parts in response to conditions at cell sites. An example process assigns a first plurality of slices and a second plurality of slices to communicate on a bandwidth of a cell site. The cell site operates at a first level of power consumption. A changed operating state is detected at the cell site, and the first plurality of slices is assigned to communicate on a bandwidth part of the cell site in response to detecting the changed operating state. The bandwidth part is a subset of the bandwidth. The cell site operates at a second level of power consumption in response to assigning the plurality of slices to communicate on the bandwidth part. The second level of power consumption is less than the first level of power consumption.

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: 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: 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.

Abstract: Disclosed is a method of operating a Radio Access Network (RAN) including a Radio Unit (RU), a first Distributed Unit (DU), a second DU that functions as a dynamic standby DU, and a network management device. After the RU transmits data to the first DU using a configuration parameter set to an address of the first DU, the RU detects an outage of the first DU. In response to detecting the outage, the RU transmits to the network management device a message indicating detection of the outage. In response, the network management device configures the second DU to perform the functions of the first DU, and causes the second DU to request the RU to set the configuration parameter to an address of the second DU. The RU then uses the configuration parameter set to the address of the second DU to transmit data to the second DU.
