Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

Network architecture, methods, and devices for a wireless communications network

A method for compensating a movement of an antenna structure having a directive antenna mounted thereto is disclosed. The method comprises obtaining sensor data from a motion sensor, where the sensor data is indicative of the movement of the antenna structure relative to a reference orientation. Moreover, the motion sensor is associated with a set of calibration parameters such that when applied to the obtained sensor data, calibrated sensor data is formed. Further, the method comprises generating a compensation signal at an output for controlling a beam direction of the directive antenna based on the formed calibrated sensor data such that the beam direction is an intended direction of the directive antenna and such that the (unwanted) movement of the antenna structure is compensated. The method further comprises re-calibrating the motion sensor in order to generate a set of calibration coefficients upon either one of an expiry of a predefined time period, a counter reaching a counter threshold, or upon a measured antenna parameter or signal parameter diverging from a parameter range. Once, one of these conditions are fulfilled, the re-calibration is performed by obtaining a received signal strength indication (RSSI) while the beam direction is controlled based on the generated compensation signal, generating the set of calibration coefficients based on the obtained RSSI, and updating the set of calibration parameters for the motion sensor with the determined set of calibration coefficients.

Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

The present disclosure relates to a metasurface arrangement including a first metasurface and a second metasurface which run mutually parallel and face each other. Each metasurface includes a corresponding periodic or quasi-periodic structure formed in a respective pattern. The first metasurface is formed in a dielectric material structure and the second metasurface is formed in either a dielectric material structure or in an electrically conducting structure. The periodic or quasi-periodic structure on the first metasurface is configured to yield a first response to an incident electromagnetic wave between the two metasurfaces, and the periodic or quasi-periodic structure on the second metasurface is configured to yield a second response to the incident electromagnetic wave between the two metasurfaces that is equivalent to the first response, thereby rendering the two metasurfaces mutually electromagnetically symmetric.
