Abstract: Systems, methods, apparatuses, and computer program products for allocation of CORESET #0 for new radio (NR). A method may include determining a control resource set zero configuration table to be applicable based on a synchronization raster of a narrowband new radio where a synchronization signal block has been detected; receiving a physical broadcast channel according to a puncturing assumption; obtaining, from a master information block indicated in the received physical broadcast channel, a row index pointing into the control resource set zero configuration table; determining information related to at least one of information of punctured or non-punctured resource blocks, or interleaving information, based on the row index; and using the determined information to determine the control resource set zero for the narrowband new radio.

Abstract: This document discloses a solution for searching a downlink control channel by a terminal device. According to an aspect, a method performed by the terminal device comprises: determining at least a first search space configuration and a second search space configuration for searching for a downlink control channel from a received signal, wherein the first search space configuration defines first starting positions and first durations for a first set of periodic search windows and the second search space configuration defines second starting positions and second durations for a second set of periodic search windows different from the first set of periodic search windows: determining a first set of periodic search spans formed by a first subset of time-domain symbols of each search window in the first set of periodic search windows and further determining a second set of periodic search spans formed by a second subset of time-domain symbols of each search window in the second set of periodic search windows: forming a sequence of search spans from the first set of periodic search spans and the second set of periodic search spans and determining a virtual search window changing in duration as dependent on a time interval between consecutive search spans in the sequence of search spans; determining, on the basis of a duration of the virtual search window, a maximum number of downlink control information candidates the terminal device is capable of processing within the virtual search window, wherein the maximum number of downlink control information candidates is configured to change together with the changing duration of the virtual search window; searching the received signal within the virtual search window for up to the maximum number of downlink control channel candidates and omitting the searching for remaining downlink control channel candidates and, upon detecting the downlink control channel, extracting downlink control information on the downlink control channel.

Abstract: Systems, methods, apparatuses, and computer program products for handling a listen before talk (LBT) failure are provided. One method may include performing, by a user equipment, listen before talk (LBT). When the listen before talk (LBT) is successful, the method may include transmitting an intended transmission subsequent to the listen before talk (LBT). When the listen before talk (LBT) is not successful, the method may include transmitting an indication of listen before talk (LBT) failure by transmitting a portion of the intended transmission subsequent to the listen before talk (LBT).

Abstract: A method includes determining, by a terminal device, at least one transmission power target level for an intended transmission on at least one sub-band. The method also includes performing a listen before talk procedure and measuring interference, and determining at least one power offset for transmission as outcome of the listen before talk procedure and the measured interference. The method further includes transmitting at least one message on at least one listen before talk allowed sub-band, using a transmission power determined based at least in part on the at least one transmission power target level for the intended transmission on the at least one sub-band, and the at least one power offset.
