IPC: H04W64/00

Abstract: Systems, methods, apparatuses, and computer program products for contention-based positioning without requiring device authentication are provided. For example, a method can include sending, by a user equipment, a positioning message to a serving network element in a network that includes multiple network elements including both the serving network element itself and at least one other network element. The positioning message can be sent as a contention-based message. The method can also include receiving, by the user equipment, a positioning response from the serving network element. Content of the positioning response can be contingent on a collision result of the contention-based message.

Abstract: Systems, methods, apparatuses, and computer program products to determine a required reconfiguration of a PARS sequence, and quickly estimate the charge time of a fully passive A-IoT tag. One method may include a UE reader determining whether a back-scatter signal for at least one known tag identifier was received for each of at least one PARS; determining whether more than one back-scatter signal for the at least one known tag identifier was received for the first of the at least one PARS; determining whether a previous increase in a total power of at least one PARS burst was performed below a granularity threshold; and calculating a current charge time of an ambient tag based upon a previous iteration.

Abstract: Based on a configuration of a pre-allocated sequence of first SSBs of a first predetermined number, which comprise second SSBs of a second predetermined number and third SSBs of a third predetermined number, a network apparatus of an access network of a cellular communication system determines (S503) a usage for resources associated with the third SSBs. According to the configuration of the pre-allocated sequence of first SSBs, the second SSBs are to be utilized in a beam management procedure including an initial access procedure and the third SSBs are not necessarily to be utilized in the beam management procedure including the initial access procedure which enables UEs to gain initial access to the cellular communication system via the access network. The network apparatus broadcasts (S505) the usage in the beam management procedure.

Abstract: Embodiments of the present disclosure relate to UL-based and DL-based positioning in a wireless communication network. A method comprises: determining, by a first device, an estimation of a propagation delay for a first reference signal to be transmitted from a second device; in accordance with a determination that the estimation of the propagation delay exceeds a threshold delay, determining a target period within a symbol on which at least a part of the first reference signal is transmitted; and performing positioning measurements on the first reference signal within the target period. As such, the receiver is capable of applying an adaptive and adjustable window for receiving different positioning reference signals (PRSs) depending on various conditions and situations. In this way, the PRS measurement performance and the positioning accuracy can be greatly improved.

Abstract: According to an aspect, there is provided an apparatus for a radio frequency front end of a beamforming transmitter or transceiver. The apparatus comprises a dual-polarized antenna element (222) for reception of electromagnetic waves transmitted by an antenna array (221) of the radio frequency front end and subsequently reflected from at least one obstruction. The dual-polarized antenna element comprises first and second feed points (223, 224) for reception of a first polarization and of a second polarization. The apparatus further comprises a switch for switching between reception of the first polarization via the first feed point and the second polarization via the second feed point.
