Abstract: Systems, methods, apparatuses, and computer program products for determining a grid-of-beams (GoB) are provided. One method may include collecting network data for training a neural network, train the neural network, using the collected data, to learn a non-discounted cumulative reward Q that evaluates a benefit of including a given beam into a grid-of-beams (GoB), iteratively applying the trained neural network to select at least one optimal beam to include in the grid-of-beams (GoB), and selecting one or more beams from the grid-of-beams (GoB) to transmit to a user equipment or to receive transmission from the user equipment.

Abstract: This document discloses a solution for selecting a transmission direction in a cell. A method comprises: determining, by a controller associated with a cell of a cellular communication system, a traffic asymmetry metric for the cell, the traffic asymmetry metric representing asymmetry between uplink and downlink traffic in the cell; comparing, by the controller, the traffic asymmetry metric with a threshold; upon determining, by the controller on the basis of the comparison, that the traffic asymmetry metric is one of greater and lower than the threshold, selecting a first transmission direction for a time interval; upon determining, by the controller on the basis of the comparison, that the traffic asymmetry metric is the other one of greater and lower than the threshold, selecting for the time interval a second transmission direction different from the first transmission direction, wherein the second transmission direction is a nominal transmission direction determined as common to a cell cluster comprising the cell and a set of neighboring cells, and wherein the controller determines the nominal transmission direction on the basis of traffic condition metrics acquired for the cell and for the set of neighboring cells; and causing data communication to the selected transmission direction in the cell during the time interval.

Abstract: As radio access network (RAN) architecture evolves and evolved packet core deployments get more distributed, there is an opportunity to provide significant optimizations of latency and processing. Certain embodiments can provide these and other benefits using vertical aggregation of radio access network and evolved packet core functionalities. A method can include operating a network element as a per-user-equipment control plane entity. The method can also include operating the network element as a first user plane entity (for example, a per-user-equipment user plane entity). The method can further include operating the network element as a second user plane entity. The method can additionally include operating the network element as a per-cell control plane entity. The method can also include operationally interconnecting the per-user-equipment control plane entity, the first user plane entity, the second user plane entity, and the per-cell control plane entity via interfaces.

Abstract: A first cell determines that UE(s) should have HARQ cycle(s) skipped, where each of the UE(s) is to take part in a CoMP transmission. Skipping is to be performed to enable the first cell to receive information from second cell(s) over backhaul link(s) for the HARQ transmission(s). A first HARQ cycle is scheduled and participated in for the UE(s) in order to receive a transmission at the first cell from the UE(s). The HARQ cycle(s) is/are skipped for the UE(s) by sending, prior to decoding information from the uplink CoMP transmissions, an acknowledgement to the UE(s) and not scheduling the UE(s) for a PDCCH grant for the HARQ cycle(s). The skipping depends on one or more of: a backhaul latency, a load in the first cell, a type of UE, or a request to the second cell(s). Apparatus and program products are also disclosed.

Abstract: Inter-radio access technology (inter-RAT) load balancing under multi-carrier dynamic spectrum sharing (SS) context is provided. One method may include splitting shared radio-frequency resources into orthogonal resource pool shares. The method may include receiving a load metric for each of a plurality of radio access technologies. The method may include assigning, based on the load metric, one of the resource pool shares to each of the plurality of radio access technologies. In addition, the method may include dynamically adjusting a proportion of the assigned resource pool shares based on the load metric of each of the plurality of radio access technologies at corresponding carriers. The method may include assigning a primary carrier to a user equipment based on the load metric, the resource pool share, a coverage of the carriers' physical channels, and a type of multi-carrier operation for each of the plurality of radio access technologies.
