An apparatus, including at least one processor, and at least one memory storing instructions, the at least one memory and the instructions configured to, with the at least one processor, cause a network device to determine excess resources available for uplink transmissions to the network device and to use at least a portion of the excess resources for a beam refinement process associated with at least one radio beam usable for an information exchange with at least one terminal device.

Apparatus comprising at least one processor

Systems, methods, apparatuses, and computer program products for identifying optimal beamforming directions from a UE by using a beamspace image. One method may include detecting radio frequency energy in a beamspace of one or more lenses; digitizing, with parallel processing of a two-dimensional array, the detected radio frequency energy in the beamspace of the one or more lenses; and generating one or more images based upon the digitized radio frequency energy in the beamspace of the one or more lenses.

Efficient beamspace imaging in wireless networks

An apparatus, comprising at least one processor, and at least one memory storing instructions, the at least one memory and the instructions configured to, with the at least one processor, cause the apparatus to sample an angular response of a uniform antenna array uniformly in a normalized angular frequency range to obtain a set of angular samples, and to reconstruct an angular response of the uniform antenna array based on the set of angular samples and at least one Dirichlet kernel.

A method, apparatus and computer program product are provided to select a plurality of antenna elements of an antenna array, such as to match the angular spread of the antenna array to a deployment scenario, thereby increasing the effective beamforming gain. In the context of a method, a plurality of antenna elements of an active antenna array are selected by separately selecting first, second and third pluralities of antenna elements and obtaining measures of first, second and third signals based upon transmission or reception of signals by the first, second and third pluralities of antenna elements, respectively The method additionally includes processing the measures of the first, second and third signals and determining a sub-army of antenna elements of the active antenna array to be utilized based on the processing of the measures of the first, second and third signals.

Method and apparatus for selecting antenna elements of an antenna array

A radio apparatus and system may include a means for modulating and/or demodulating an optical signal for respective transmission and/or reception of the optical signal using an optical channel connected to a remote radio unit. There may also be provided a means for performing, based on one or more pre-trained computational models, one or more operations on a digital signal corresponding to the optical signal for mitigating one or more non-linearities introduced by the optical modulating and/or demodulating means and the optical channel. The one or more pre-trained computational models may be pre-trained based on feedback data indicative of said one or more non-linearities.
