Abstract: A node (321, 322, 323) of a communication network configures multiple IP addresses of the node (321, 322, 323). Each of the multiple IP addresses are associated with a corresponding IP network (311, 312, 313) to which the node (321, 322, 323) is connected. Each of the these IP networks (321, 322, 323) is identified by a corresponding network identifier. In response to a request sent by the node (321, 322, 323), the node receives connection information of a further node (321, 322, 323) of the communication network. The received connection information includes at least one network identifier and an associated IP address of the further node (321, 322, 323). Based on the at least one network identifier, the node (321, 322, 323) selects one of the IP networks (311, 312, 313). Via the selected IP network (311, 312, 313) and based on the associated IP address, the node (321, 322, 323) establishes an IP based connection to the further node (321, 322, 323).

Abstract: Systems and methods for ultra-wideband Crest Factor Reduction (CFR) are provided. In some embodiments, a method performed by a wireless node for performing CFR includes performing a first CFR step on a plurality of input signals at a first sampling rate with joint peak detection and band-specific noise shaping; and performing a second CFR step on the resulting plurality of input signals at a second sampling rate with joint peak detection and joint noise shaping where the second sampling rate is higher than the first sampling rate. In this way, Peak-to-Average Power Ratio (PAPR) reduction may be increased while the computational complexity is reduced.

Abstract: A method performed by a first Radio Control Node (RCN) for handling a radio connection to be established in a second beam controlled by a second RCN for the UE served in a first beam controlled by the first RCN. When the radio connection of the UE, served in a first beam controlled by the first RCN, has been established in the second beam controlled by a second RCN, the first RCN obtains feedback from the second RCN. The feedback relates to information about the characteristics of the radio connection in the second beam resulting from measurements performed when the radio connection has been established between the UE and a second radio node providing the second beam. The first RCN then provides for the radio connection to be established in the second beam controlled by the second RCN for any UEs served in the first beam.

Abstract: The present disclosure relates to a base station in a cellular communication network and methods of operation thereof. In one embodiment, a base station determines that the base station is transitioning to an unavailable state. The base station then notifies one or more radio network nodes with which the base station conducts base-station-to-node communication that the base station is unavailable. Thereafter, in one embodiment, the one or more radio network nodes cease communication attempts with the base station. In this manner, the radio network nodes can avoid spending additional resources on attempts to re-establish communication connections to base stations that tend to be offline more often (e.g., low-power base stations (LP-BSs)).

Abstract: A node (321, 322, 323) of a communication network configures multiple IP addresses of the node (321, 322, 323). Each of the multiple IP addresses are associated with a corresponding IP network (311, 312, 313) to which the node (321, 322, 323) is connected. Each of the these IP networks (321, 322, 323) is identified by a corresponding network identifier. In response to a request sent by the node (321, 322, 323), the node receives connection information of a further node (321, 322, 323) of the communication network. The received connection information includes at least one network identifier and an associated IP address of the further node (321, 322, 323). Based on the at least one network identifier, the node (321, 322, 323) selects one of the IP networks (311, 312, 313). Via the selected IP network (311, 312, 313) and based on the associated IP address, the node (321, 322, 323) establishes an IP based connection to the further node (321, 322, 323).
