    Abstract: Systems, methods, apparatuses, and computer program products for dynamic antenna array angular phase deviation compensation for broad beam positioning. For example, certain embodiments may provide for multi-round trip time (multi-RTT) positioning where a user equipment (UE) may report time of departure (TOD) compensation values to a serving gNB and/or location management function (LMF). The LMF may calibrate the RTT computation with the received TOD compensation values. As another example, certain embodiments may provide for uplink time difference of arrival (UL-TDOA) positioning where an LMF may signal calculated assistance information to the UE to request time of departure TOD compensation values. The UE may report the TOD compensation values to a location management function (LMF), and the LMF may compensate initial relative time of arrival (RTOA) estimates using the TOD compensation values.

    Abstract: According to an aspect, there is provided a radio frequency front end (202) for a beamforming transceiver (201) having an antenna array comprising a plurality of antenna elements. The radio frequency front end comprises, for each antenna element, at least two radio frequency beamforming branches (218, 219). Each of at least one of said at least two radio frequency beamforming branches comprises an electrically tunable phase shifting element (221, 231), first and second transmission/reception switches (223, 233), a low-noise amplifier (225, 235) for reception and a power amplifier (224, 234) for transmission. Moreover, each of at least one of said at least two radio frequency beamforming branches comprises an electrically switchable matching circuit (226, 236). The electrically switchable matching circuit comprises two or more matching circuit settings selectable via switching. Each of the two or more matching circuit settings is configured for providing impedance matching for an antenna element at one or more beam steering angles in transmission.

    Abstract: Certain examples of the present invention relate to carrier management in a wireless communication network. Certain examples provide a User Equipment, UE, comprising: means for receiving, following a maximum permissible exposure, MPE, event occurring during operation over a first carrier such that the UE is no longer operating over the first carrier, a first signal, over a second carrier, for configuring the UE to determine a status of the MPE event associated with the previously used first carrier; means for determining, responsive to receipt of the first signal, a current status of the MPE event associated with the previously used first carrier; and means for transmitting, responsive to receipt of the first signal, a second signal over the second carrier, wherein the second signal comprises an indication of the current status of the MPE event associated with the previously used first carrier.

    Abstract: An apparatus for use by a UE configured to conduct a communication in a communication network. The apparatus is configured to receive and process signals from the communication network via signal receiving portions, wherein one of the signal receiving portions is a serving cell signal receiving portion used for connecting to the communication network via a serving cell, and another of the signal receiving portions is a non-serving cell signal receiving portion being not used for connecting to the communication network. A signal receiving portion specific offset value is obtained for each of the signal receiving portions. Signal quality values for signals received by the signal receiving portions from the communication network are measured, wherein the cells include the serving cell. A measurement report is sent to the communication network on the basis of the results of the signal quality measurements and the offset values for the signal receiving portions.

    Abstract: Various example embodiments provide a system for mitigating effects of a power back-off due to exposure of user's body to transmitted power. A user equipment (UE) may determine triggering of a power exposure event, for example a body of a user coming close enough to trigger a maximum permissible exposure (MPE) limit. The UE may then send an emergency signal including an indication of the triggered power exposure event to a base station. Various beneficial options for rapidly providing the emergency signal are disclosed. The UE and the base station may enter an emergency mode, where the UE may provide further information on its power back-off conditions. Based on the information received from the UE, the base station may determine to perform adaptation of the radio link to avoid radio link failure. Apparatuses, methods, and computer programs are disclosed.

    Abstract: An arrangement for determining a location of a base station by user equipment uses measurements of reference signals of a base station from different user equipment positions. The measurement results are preprocessed and then provided to a machine learning entity. The machine learning entity estimates the location of the base station and provides the estimated location for use in other functionality of the user equipment.

    Abstract: Embodiments of the present disclosure relate to a terminal device (200) and a communication system (900) comprising at least one terminal device (902). The terminal device (200) comprises first circuitry (214) coupled to an antenna (202) and configured for a binary phase shift keying (BPSK) modulation based on a dual frequency signal received via the antenna. A first frequency part (204) of the dual frequency signal matches the antenna resonance frequency and is used for charging an energy storage, and a second frequency part (206) of the dual frequency signal is used for performing the BPSK modulation at a mismatched frequency of an antenna impedance. The terminal device (200) also comprises second circuitry (212) coupled to the first circuitry and configured to control a state of the first circuitry for performing the BPSK modulation. The terminal device can support BPSK backscatter with low complexity, cost, and a small size.
