Abstract: An apparatus is disclosed, comprising means for identifying a plurality of user equipment (UE), each transmitting one or more uplink packets for decoding at a base station associated with a given cell of a radio network. The apparatus further comprises means for clustering the identified user equipment into joint processing groups, each joint processing group comprising the identities of two or more user equipment as clustered and means for performing, in a first processing stage, joint processing of the uplink data streams for identified user equipment within common joint processing groups using one or more first processing algorithms to produce corresponding first processed uplink data streams. The apparatus further discloses means for performing one or more subsequent processing stages on the first processed uplink data streams, subsequent to the joint processing, to produce decoded uplink data streams, the one or more subsequent processing stages using one or more second processing algorithms, different from the first processing algorithm.

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.
