Abstract: To position a terminal device, at least one transmission-reception point, or corresponding apparatus, the terminal device and a network entity exchange information. A transmission-reception point receives from the network entity a first signal comprising at least one parameter setting for positioning reference signal transmissions. The terminal device receives from the network entity a second signal comprising at least the parameter setting. The network entity receives from the transmission-reception point a first report indicating at least an occurrence time of a successful transmission of a positioning reference signal and from the terminal device a measurement report comprising information on at least the positioning reference signal. The network entity determines a position of the terminal device based on at least the first report and the measurement report.

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: A method for a user equipment includes determining full duplex capability and metric thresholds during cell search or attachment to a base station and reporting these to the base station; when in an RRC-connected state, dynamically sending reports of the metric conditions to the base station; and receiving instructions, based on the reports of the metric conditions, to communicate with the base station in one of a full duplex mode and a time division duplex mode. A method for a base station includes receiving a full duplex capability and metric thresholds from a user equipment; when in an RRC-connected state, initially scheduling the user equipment for communications in a time division duplex mode; receiving reports of metric conditions dynamically from the user equipment; and sending instructions, based on the reports, to the user equipment to communicate in one of a full duplex mode and a time division duplex mode.
