Abstract: Wake-up signal beacon arrangement for wake-up signal coverage detection is provided. A method for wake-up signal beacon arrangement for wake-up signal coverage detection may include receiving at least one configuration for a first wake-up signal beacon and a second wake-up signal beacon. A power or energy of the second wake-up signal beacon may be lower than a power or energy of the first wake-up signal beacon. The method may also include monitoring a current cell for wake-up signal beacons during a wake-up signal mode using the received at least one configuration, and modifying the monitoring of the current cell based on a detection metric. The detection metric may be determined based on at least the second wake-up signal beacon.

Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for control short control signal (SCS) in downlink. For example, certain embodiments may provide for a method examining whether a signal to be transmitted by a network element belongs to a first group or to another group based on a transmission time instance of the signal, a beam or beams of the signal, a beam index or beam indices of the signal and/or a type of the signal; determining an allowance of time or resources of a time period for one or more short control signals; determining whether to transmit the signal as one or more short control signals based on the group the signal belongs to and on the allowance; and transmitting the signal either as one or more short control signals, or as a signal subject to listen before talk procedure.

Abstract: According to an example aspect of the present invention, there is provided an apparatus configured to select a reference signal sequence, determine a number of resource blocks located outside a frequency interval via spectrally extending the signal, and when the number is an odd number, perform exactly one of the following: symmetrically extend a cyclically shifted version of the selected reference signal sequence, or asymmetrically extend the selected reference signal sequence without shifting it, map the extended reference signal sequence to resource blocks located in the frequency interval and resource blocks located outside the frequency interval, perform spectral shaping of a second signal comprising the resource blocks located both inside and outside the frequency interval, and transmit the second signal in uplink direction.

Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for control short control signal (SCS) in uplink. For example, certain embodiments may provide for regulating the amount of uplink (UL) transmissions in a cell, such that SCS limitations are not violated. Certain embodiments may relate to a situation where a single SCS allowance or multiple SCS allowances may be in use in the cell and, e.g., a single SCS allowance may be shared between a gNB and the UEs, or a single SCS allowance may be shared between the UEs.

Abstract: Systems, methods, apparatuses, and computer program products for blind physical broadcast channel detection for narrowband new radio. The method may include detecting at least one synchronization signal. The method may also include determining, in response to detecting the synchronization signal, whether one or more predefined conditions of a user equipment have been met. At least one candidate pattern of a physical broadcast channel may be determined when the one or more predefined conditions have been met. The physical broadcast channel may be received with the at least one candidate pattern of the physical broadcast channel. Based on a determination of whether the physical broadcast channel was correctly received, a system information block physical downlink control channel may be received with the at least one candidate pattern of the physical broadcast channel, or the at least one candidate pattern of the physical broadcast channel may be modified.

Abstract: Devices, methods and computer programs are disclosed for enabling single carrier transmission of multiple downlink control information blocks. A network and client devices may operate according to multiple search space configurations. A first search space configuration may be used to transmit and receive downlink control data containing a single downlink control information block. A second search space configuration may be used to transmit and receive downlink control data containing multiple downlink control information blocks.
