Abstract: A method, apparatus and computer program is described comprising: receiving data transmitted over a wireless channel (the data encoding a first estimate of a channel state information of the wireless channel); decoding said data to generate a second estimate of the channel state information of the wireless channel; and generating a channel state information output by modifying the second estimate of the channel state information based, at least in part, on a first error indication.

Abstract: Various example embodiments relate to relate to network nodes (20A; 20B), methods and computer program products configured to hand over a communication link between a cell and user equipment (10) in a wireless communication network from a source cell (40A) to a target cell (40B; 40C). According to various, but not necessarily all, embodiments of the invention there is provided a node (20A), comprising: means configured to establish a communication link between a source cell (40A) and user equipment (10); means configured to transmit a series of data packets to the user equipment (10), each data packet comprising an associated sequence identifier; means to receive an acknowledgement of successful receipt of a data packet of the series by user equipment (10), the acknowledgement comprising an indication of the successfully received data packet sequence identifier; means configured to receive an indication of an identified handover target cell (40B; 40C); means configured to request handover of the user equipment (10) to the identified handover target cell (40B; 40C); means configured to receive an acknowledgement of handover request from the identified handover target cell (40B; 40C); and means to forward data packets to be transmitted to user equipment (10) to the identified target cell (40B; 40C), the forwarded data packets comprising the indication of associated sequence identifier and the most recent successfully received data packet sequence identifier. Also provided is a node (20B), comprising: means configured to receive a request for handover of user equipment (10) from a source cell (40A) to a target cell (40B; 40C); means configured to transmit an acknowledgement of handover request to the source cell (40A); and means to receive forwarded data packets forming a series of data packets to be transmitted to user equipment (10), the forwarded data packets comprising an indication of a sequence identifier associated with each forwarded data packet and an indication of a most recent successfully received data packet sequence identifier. Arrangements recognise that one way to mitigate some of the negative effects associated with early data forwarding, for example, the increased use of network memory and the risk of duplicate transmissions, is by providing a mechanism supported by a source (20A) and target node (20B) to allow a target access node (20B) to perform efficient data discarding.

Abstract: Systems, methods, apparatuses, and computer program products for energy-efficient precoding with controllable power distribution. A method may include generating a digital precoder with controllable flatness based on at least one of a plurality of control parameters. The method may also include controlling flatness of a power distribution across a set of antennas, panels, or access points. The method may further include balancing, based on the control of the flatness of the power distribution, spectral efficiency and energy efficiency according to respective predefined values of spectral efficiency and energy efficiency. The balancing may include adjusting the at least one of the plurality of control parameters.

Abstract: According to an update procedure for a network of interconnected nodes, a node keeps track of markers received on the node's incoming channels, transmits a marker on each outgoing channel (if any exist), and updates its node configuration from an old configuration to a new configuration. In one version of the update procedure, the node updates its configuration and transmits markers after receiving its initial incoming marker. In another version for acyclic networks, the node updates its configuration and transmits markers after receiving its final incoming marker. The node determines how to handle (i.e., process, queue, or drop) each incoming data packet based on (i) whether or not it has updated its node configuration yet and (ii) whether or not it has received a marker on the corresponding incoming channel yet. A controller initiates the update process at a subset of nodes that ensures eventual completion of the update process.

Abstract: A technique is provided for beamforming training, including: transmitting, by a network node, common control signaling via a plurality of beams periodically according to a predetermined beam sweeping pattern, and transmitting, via a set of one or more beams in each of one or more sequential time-domain resources, an aperiodic downlink sounding burst to at least one user device to allow the at least one user device to perform beamforming training.

Abstract: Example embodiments of the present disclosure relate to channel state based beamforming enhancement. A first device receives, from a second device, a second message indicating a second channel state. The second message has a second length less than a first length of a first message indicating a first channel state previously received from the second device. The first device obtains combined beamforming features of the second device according to a trained combining model associated with the second device and based on the second message and historical beamforming features of the second device. The first device generates a beam weight for the second device according to a trained beamforming model and based on the combined beamforming features. The first device may generate a beam weight for the second device according to the beamforming model without recovering CSI from the message.
