Abstract: A system, method and non-transitory computer readable media for facilitating adaptive anchor layer mobility in a 5G NSA implementation. In one arrangement, a handover modulation criterion involving relevant trigger parametrics of an anchor cell node serving a UE and a target cell node may be compared against a tunable threshold parameter indicative of the effect of the target cell on the anchor cell quality. If the handover modulation criterion does not exceed the tunable threshold value, a quality degradation prediction with respect to the UE may be executed to estimate a likelihood of service failure for the UE. Responsive to determining that the likelihood of service failure does not exceed a probability threshold, handover of the UE to the target cell may be suppressed.

Abstract: The present application relates to a computer implemented method for managing connectivity of a wireless device in a cellular communication network, wherein the wireless device is operable to connect to a cell of a first radio-access technology, RAT, and to a cell of a second RAT. The method includes receiving location information for the wireless device, wherein the wireless device is connected to a first RAT cell hosted by the serving radio access node, and is also connected to a second RAT cell, and wherein a signal strength of the second RAT cell, received at the wireless device, has fallen below a trigger threshold. The method further includes identifying neighbour first and second RAT cells, and assembling, a candidate set of cell combinations.

Abstract: A method, performed by a first node (111) serving a wireless device (130) in a secondary cell group (122), to handle a change of the device (130) from a first cell (123) to a second cell (124). The first node (111) determines (609) whether to proceed or to suspend the change, with the proviso that a probability of RLF at the first cell (123) is under a threshold. The determining (609) is based on whether or not a predicted quality of communication between the wireless device (130) and the second cell (124) exceeds another threshold. The first node (111) sends (610) an indication to a second node (112) indicating to proceed with the change, wherein the first node (111): i) if the result is to proceed with the change, sends the indication, and ii) if the result is to suspend the change, refrains from sending (610) the indication and suspends the change.

Abstract: A network node in a telecommunications network can measure a first throughput associated with a first communication channel between the network node and a communication device. The first communication channel can include an active communication channel that uses a first radio access technology, RAT. The network node can further predict a second throughput associated with a second communication channel between the network node and the communication device if communication associated with the communication device was switched to the second communication channel. The second communication channel can include an inactive communication channel that uses a second RAT. The network node can further determine to switch the communication associated with the communication device to the second communication channel based on the first throughput and the second throughput.

Abstract: A computer-implemented method for adaptive beam management for load balancing communication devices over ports used for a channel state information reference signal, CSI-RS, in a telecommunications network. The method includes predicting from a machine learning model predicted channel quality indicator, CQI, values for target beam candidates for offloading one or more communication devices. The method includes identifying a target beam candidate having a highest CQI value from the predicted CQI values. The method includes deciding to offload the one or more communication devices from an offload beam candidate to the target beam candidate when a difference between the highest CQI value of the target beam candidate and a CQI value of the offload beam candidate is greater than or equal to a threshold value. The method includes initiating offloading of the one or more communication devices from the offload beam candidate to the target beam candidate.

Abstract: A method performed by a random access channel planning node. The random access channel planning node may identify a coverage overlap area of a candidate cell with each of the neighboring cells of the candidate cell in a radio access network. The random access channel planning node may use the identified coverage overlap area to determine a root sequence index for the candidate cell having a minimum root sequence index collision factor. The random access channel planning node may initiate a command to the candidate cell to set the root sequence index for the candidate cell to the determined root sequence index having the minimum root sequence index collision factor.

Abstract: A method performed by a network node for handling load balancing of at least one User Equipment (UE) is provided. The at least one UE has performed a respective handover to a Second Frequency, F2, carrier provided by the network node in a communication within a wireless communication network. The network node evaluates (201) whether or not each of the at least one UE has resided at the F2 carrier for a respective time period which is below a first threshold value. The network node decides (202) that one or more first UEs out of the at least one UE shall be put through a further evaluation for load balancing when any one or more of the first UEs have resided at the F2 carrier for a respective time period which is below the first threshold value. The network node decides (203) that each one or more second UEs out of the at least one UE is a candidate for load balancing when any one or more of the second UEs have resided at the F2 carrier for a respective time period which is not below the first threshold value.

Abstract: A management node and method at the management node provide automatic PCI allocation to sites in a RAN by iteratively identifying a selected cell site to be allocated a PCI group. From a group of cell sites in the RAN that have already been allocated a PCI group, the method obtains, for each PCI group, a closest neighbor site having a least distance from the selected cell site.

Abstract: A node of a wireless communication network receives a first request for establishment of a connection between a communication device and the wireless communication network. Upon receiving the first request, the node starts a timer and establishes a context for the connection between the communication device and the wireless communication network. Further, the node receives a second request for establishment of a connection between a communication device and the wireless communication network. Depending on a state of the timer when receiving the second request, the node selects between: A) establishing an additional context for the connection between the communication device and the wireless communication network while maintaining the established context, and B) releasing the established context and establishing a new context for the connection between the communication device and the wireless communication network.

Abstract: Systems and methods are disclosed for improving Physical Downlink Control Channel (PDCCH) allocation for improved downlink scheduling. In some embodiments, a method of operation of a network node in a cellular communications network comprises transmitting a downlink assignment to a wireless device, the downlink assignment comprising an indication of whether the downlink assignment applies to a single Transmit Time Interval (TTI) or multiple consecutive TTIs, and transmitting a downlink data transmission to the wireless device during a single TTI or multiple downlink data transmissions to the wireless device during multiple consecutive TTIs according to the downlink assignment. In this manner, the network node does not need to transmit, and the wireless device does not need to receive/decode, a separate downlink assignment in each TTI. This may be beneficial to, e.g., mitigate PDCCH congestion.
