Abstract: Example embodiments of the present disclosure relate to methods and apparatuses for codebook-based uplink transmission. A first apparatus obtains a codepoint value and determines at least one table entry for precoding based on the codepoint value. The codepoint value indicates selection of a transmission mode and one or multiple maximum ranks, and at least a maximum rank of a first codepoint value is different from a maximum rank of a second codepoint value. Through this solution, multi-panel simultaneous transmission in the scenarios of single and multiple transmission-reception points (TRPs) can be supported in a simple and easily adoptable way.

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: Systems, methods, apparatuses, and computer program products for beam failure detection and/or beam failure recovery procedures, for instance, for multi-panel user equipment (UEs) are provided. One method may include transmitting, by a UE, a beam report to a network to indicate an association between at least two downlink reference signals and at least two antenna panels at the user equipment or to indicate a selection of at least two downlink reference signals that will be used for downlink reception at the user equipment simultaneously. The method may also include activating the antenna panels corresponding to one or more of the at least two downlink reference signals, based on transmission configuration indicator (TCI) states updated by the network or based on the selection of the at least two downlink reference signals, and detecting beam failure based on at least two sets of beam failure detection resources for the active antenna panels.
