摘要： 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.

摘要： 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.

摘要： An apparatus, which comprises at least one antenna array comprising a plurality of array elements having cross-polarized coupled branches, is configured to adjust at least its uplink beam steering direction by measuring (301), while transmitting a combined uplink signal via the plurality of the an-ay elements as individual signals forming the combined uplink signal, per an array element, first signal on an unused branch of the array element, and using the first signal and reference information in the memory to adjust if needed, at least one beam steering setting.

摘要： Aspects and embodiments relate generally to mechanisms to support power saving in a wireless communication network and more particularly to supporting discontinuous reception of a wake-up signal receiver at an apparatus comprising a wake-up signal receiver and a main radio receiver. One aspect provides an apparatus, comprising: a main radio receiver; a wake-up signal receiver; and a timer. The wake-up signal receiver comprises: circuitry configured to receive at least a portion of a broadcast message; circuitry configured to evaluate the received portion of the broadcast message to determine a time marker; and circuitry configured to provide the time marker to the timer. The apparatus may comprise a UE and may therefore be configured to align internal time keeping with the time keeping of a network, thus allowing discontinuous reception and associated energy savings, without transmission of additional specific synchronisation messaging by a network.

摘要： Systems, methods, apparatuses, and computer program products for asset tracking joint sounding reference signal (SRS) transmission. A location management network node may send a positioning failure message to a serving network node. The serving network node may group devices if one or more criteria are met. When one or more of the devices can be grouped, the serving network node may assign and distribute, to devices, a multi-tag-SRS sequence identifier that may be used by the devices in the group. The serving network node may compute and send, to the devices in the group, a multi-tag-SRS transmit configuration. The devices may perform a joint SRS transmission. The location management network node may compute a location of a centroid for the group of devices associated with the reported metric.
