Abstract: There are provided measures for enabling/realizing pathloss measurement on an unlicensed spectrum, i.e. arrangement of an appropriate pathloss reference signal for operation on an unlicensed spectrum. Such measures exemplarily comprise that a communication node or element in a communication system, which is configured for beam-based operation on an unlicensed band, obtains a pathloss measurement configuration, including a reference signal for pathloss measurement, validates practicability of pathloss measurement based on the configured reference signal, and controls pathloss measurement, wherein pathloss is measured based on the configured reference signal in a case where the configured reference signal is practicable, or pathloss measurement is skipped or pathloss is measured based on another reference signal being on the same quasi-co-location chain as the configured reference signal in a case where the configured reference signal is not practicable.

Abstract: Systems, methods, apparatuses, and computer program products for facilitating robustness for synchronization signal block (SSB) are provided. A network node may attempt to transmit SSBs in first positions. For example, the network node may perform a listen-before-talk (LBT) procedure prior to transmitting the SSBs, and transmissions of the SSBs may fail or succeed based on failure or success of the LBT procedure. If the transmissions fail, the network node may attempt to transmit the failed SSBs in second SSB positions. For example, the second SSB positions may be associated with the first positions, and may be reserved for retransmission of SSBs that fail in the corresponding first positions. If the network node transmits the SSBs, the UE may perform various operations described herein including, e.g., determining whether the SSBs were transmitted in the first positions or the second positions and/or an SSB index or timing.

Abstract: There is provided a method, comprising: determining a presence indicator configuration defining how a presence indicator is to be interpreted, wherein, based on the configuration, the presence indicator indicates whether a set of one or more configured reference signal occasions of a cell carries reference signals; obtaining from a base station the presence indicator; obtaining from the base station at least one reference signal configuration, each indicating at least one configured reference signal occasion; and determining, based on the presence indicator and the obtained presence indicator configuration, whether a given reference signal occasion indicated by the at least one reference signal configuration carries a reference signal.

Abstract: A method and apparatus for dynamically adapting scheduling parameter(s) to achieve power savings. A user equipment may be configured with one or more offsets between scheduled PDCCH and PDSCH transmissions. The user equipment may receive from a network an indication to dynamically change these offsets. If the user equipment sleeps through a first transmission of this indication, upon next receiving the indication the user equipment may update, for example, the offset in a time domain resource allocation table. The indication to dynamically change an offset may be an indication of an offset including fewer slots. A change to the offset, with which downlink transmission is expected by the user equipment, may be disabled. A network node may be configured to transmit downlink traffic to the user equipment according to a configured offset and/or according to an offset the network node indicated to the user equipment.
