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: To enable at least dynamic waveform switching, at least one predefined bit, in a downlink control information comprising scheduling information for at least one uplink transmission, may have a first preset purpose and a second preset purpose. One or more preset first rules may be applied to determine whether to use the at least one predefined bit for the first preset purpose or for the second preset purpose. When the second preset purpose is used, at least a waveform for the at least one uplink transmission amongst waveforms comprising at least a first waveform and a second waveform is determined, according to one or more preset second rules, based on a value of the at least one predefined bit. The waveform determined is then used in the uplink transmission scheduled.

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: Implementations of advanced frequency synchronization in a mobile integrated access backhaul deployment are disclosed. An apparatus includes at least one processor, and at least one non-transitory memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to perform: estimate a change in a propagation delay at two time instants, measure a time period of the two time instants using a local clock of a network node, wherein the two time instants correspond to a known timing of a received signal, subtract the change of the propagation delay from the measured time period, calculate a difference between the subtracted time period and a known timing of the received signal; and convert the difference to a frequency offset value to synchronize downlink transmission frequency between the network node and a parent node.
