Abstract: An approach is provided for cell re-selection. A notification message is generated to indicate initiation of a coverage area re-selection procedure to operate in a new coverage area from a current coverage area. The re-selection procedure is performed if an acknowledgement message is received in response to the notification message.

Abstract: Embodiments of the present disclosure disclose devices, methods and apparatuses of coherent joint transmission. A terminal device may receive a QCL source configuration from a network device. The QCL source configuration may indicate at least two transmission configuration indication (TCI) states that indicate reference signals from valid QCL sources for a coherent joint transmission (CJT) of tracking reference signals (TRSs).

Abstract: Various example embodiments may relate to punctured transmission of data within synchronization signal blocks. An apparatus may obtain data for transmission on a data channel of a synchronization signal block of a transmission frame and allocate the data to resource elements of the data channel. The allocation of the data may be dependent on the frame number of the transmission frame. The apparatus may further puncture one or more resource elements at edge(s) of the synchronization signal block and transmit the synchronization signal block. Another apparatus may receive the synchronization signal block and decode the data. Apparatuses, methods, and computer programs are disclosed.

Abstract: There is provided a user equipment apparatus that includes at least one processor and at least one memory. The memory stores instructions which, when executed by the at least one processor, cause the user equipment apparatus at least to: perform an initial cell search of one or more cells on a network, including scanning for synchronization signal block (SSB) transmissions corresponding to synchronization raster points; receive an SSB transmission associated with a synchronization raster point and with a transmission bandwidth, where a size of the transmission bandwidth is based on location of the synchronization raster point in a band having at least a first region and a second region, and where the SSB transmission includes a physical broadcast channel (PBCH); and determine a PBCH puncturing pattern for receiving the PBCH based on the size of the transmission bandwidth.

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.
