Abstract: Systems, methods, apparatuses, and computer program products for managing or monitoring of the control channel in new radio (NR) through blind searches are provided. One method may include determining whether a channel estimation limit has been reached for a user equipment. When it is determined that the channel estimation limit has been reached, the method may include selecting blind decoding candidate(s) to be dropped from different control resource set(s) or search space set(s), and removing the selected blind decoding candidate(s) from a set of monitored candidates.

Abstract: Example embodiments relate to wideband communications based on availability assessment. A method for communication comprises performing availability assessment on a set of configured frequency subbands to obtain an availability result, the availability result indicating that at least one of the set of configured frequency subbands is available for a period of time for transmission of intended information and transmitting supplementary information that has been prepared using the at least one frequency subband during a first portion of time within the period of time. The method also comprises preparing the intended information based on the availability result and transmitting the prepared intended information using the at least one frequency subband during a second portion of time following the first portion of time within the period of time. As such, the processing of the intended information can be adapted depending on the dynamic available subband (s) indicated by the availability result.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable mediums for downlink control of unlicensed sub-bands. The method comprises determining a search space configuration associated with control resources on a plurality of sub-bands which are unlicensed, the search space configuration indicating candidates for detection of downlink control information for the plurality of sub-bands; determining, from the search space configuration, positions of the candidates on the control resources within each of the plurality of sub-bands; mapping an available number of candidates to the determined positions based on a transmission bandwidth assumed by a terminal device; and transmitting downlink control information to the terminal device on the mapped candidates.

Abstract: Systems, methods, apparatuses, and computer program products for managing or monitoring of the control channel in new radio (NR) through blind searches are provided. One method may include configuring, by a network node, multiple search spaces, sets of search spaces, and/or control resource sets, to a user equipment, that results in monitoring occasions where more blind decodings are required than allowed by capability of the user equipment. The method may further include identifying the monitoring occasions for which an allowed number of blind decodings is exceeded, determining a reduced set of blind decodings and/or candidates determined by predefined search space priorities or rules, and transmitting physical downlink control channel(s) to the user equipment given the reduced set.

Abstract: Synchronization signal numerology of a communications system is determined, on the basis of at least two reference numerologies. Time occasions comprising including synchronization signals are determined on the basis of a first reference numerology of the at least two reference numerologies for synchronization signal numerologies. Positions of the synchronization signals within the determined time occasions are determined on the basis of a second reference numerology of the at least two reference numerologies. Positions of the synchronization signals according to the synchronization signal numerology are determined at least on the basis of the determined time occasions and the positions within the time occasions. The synchronization signals are received at the determined positions. In this way, the synchronization signal block duration may be extended in time and/or the number of synchronization signal blocks may be increased without introducing a need for a new numerology for synchronization signal numerologies.

Abstract: According to an example aspect of the present invention, there is provided a method, comprising: receiving, by a first device from a second device, a message on a wireless medium indicating that the wireless medium has been reserved for at least one transmission from the first device to the second device by the second device detecting that the wireless medium is not occupied, based on a first beamwidth. The method further comprises determining, by the first device, a second beamwidth for performing the at least one transmission, selecting, by the first device on the basis of the received message, a method for the first device, from a set of at least two methods, to determine whether the wireless medium is occupied, determining, by the first device, based on the selected method for the first device whether the wireless medium is occupied, and in response to detecting that the wireless medium is not occupied, performing the at least one transmission by the first device.
