Abstract: Implementations describe a user equipment, an access node, and to methods for a user equipment and for an access node. The user equipment includes a receiver configured to receive a downlink control signal (CTRLS) over a downlink control channel (PDCCH) from an access node. The user device also includes a processor configured to, when the user equipment is in a Radio Resource Control (RRC) connected mode, switch on the receiver at a time point (tstart_symbol) when a symbol comprising the downlink control signal (CTRLS) starts in time domain. The processor is further configured to switch off the receiver at a time point (tend_symbol) when the symbol comprising the downlink control channel (CTRLS) ends in time domain.

Abstract: Implementations described herein relate generally to a user device, to an access node, and to methods for a user device and for an access node. The user device includes a receiver configured to receive at least one downlink signal from an access node. The user device further includes a processor configured to measure the at least one downlink signal at two time instants, to determine if a difference of the measured at least one downlink signal at the two time instants exceeds a threshold, and to generate, when the difference exceeds the threshold, at least one uplink transmission. The user device further includes a transmitter configured to transmit the at least one uplink transmission over an uplink random access channel.

Abstract: A wearable device to estimate an individual's maximum oxygen uptake (VO2max) during exercise. The wearable device includes a processor and a memory. The processor is configured to receive heart-rate measurement data and exercise workload data for an individual of the wearable device. The memory stores instructions that cause the processor to obtain the heart-rate and exercise workload of the individual, normalize the heart-rate with respect to the individual's maximum heart-rate to provide a data pair of normalized heart-rate (HRn) and exercise workload (w), and apply a probabilistic model that relates HRn to w and maximum oxygen uptake to provide an estimate of maximum oxygen uptake (VO2max) of the individual.

Abstract: Device, method and computer program to make better use of measurements of received signals for determining location are provided. A client device is configured to receive a signal that contains a reference symbol modulated onto a plurality of subcarriers. The client device determines a plurality of weights based on the reference symbol and line-of-sight channel frequency responses for the subcarriers, so that each of the plurality of weights is associated with one of the subcarriers. The client device determines a gain associated with the received signal using the plurality of weights. A network device may receive from the client device information indicative of gains, wherein a gain indicates a signal strength at which the client device was able to receive a respective signal. The location of the client device may be determined by using information about network device locations, transmission directions, and the gains.
