Abstract: Systems, methods, apparatuses, and computer program products for beam group-based downlink transmit beam indication. Certain embodiments may provide enhancements related to physical layer design for multiple input multiple output and/or enhancements for a beam indication framework for scenarios with multiple transmission reception points and user equipment equipped with multiple antenna panels. A network node may transmit, and a user equipment may obtain, information indicating that one or more activated transmission configuration indictor states are associated with a set of beam groups.

Abstract: A method, apparatus, and computer program product modifying the usage of control resources for data transmission by focusing on reducing overhead of the control channel in order to maximize the spectral efficiency by configuring physical resources into two parts for an allocation into control information for the first part, and data for both the first part and the second part or data for only the second part. Data allocation in the first part based is derived based on the data allocation in the second part and the control information allocation in the first part. The number of control symbols within a subframe or transmission time interval is minimized on the downlink control signaling, used mainly for downlink and uplink grant signaling, and for the uplink HARQ ACK/NACK feedback. Where overhead is not the only problem, usage of two symbols is proposed due to the limitations of radio frequency beamforming.

Abstract: Systems, methods, apparatuses, and computer program products for selecting or prioritizing between a physical downlink shared channel (PDSCH) and synchronization signal block (SSB) reception are provided. One method may include, when outside a SMTC window and when PDSCH resource allocation overlaps with an occupied SSB location, selecting between the PDSCH and SSB reception according to defined rules.

Abstract: There are provided measures for improved beam indication. Such measures exemplarily comprise storing at least one beam determination entry, wherein each of said at least one beam determination entry is indicative of a respective first beam and at least one respective second beam narrower than said first beam and at least partially in quasi co-location with said first beam, receiving indicator information indicative of one of said at least one beam determination entry, and selecting, for a predetermined physical channel, a transmission beam out of said first beam and said at least one second beam of said indicated one of said at least one beam determination entry based on receiving power measurement results in relation to said first beam and said at least one second beam of said indicated one of said at least one beam determination entry.

Abstract: Various communication systems may benefit from appropriate assumptions regarding physical or electrical characteristics of the systems. For example, fifth generation (5G) or similar communication systems may benefit from appropriate antenna co-location and receiver assumptions. A method can include receiving an indication of a set of co-location rules to apply from at least three sets of co-location rules. The method can also include applying the indicated set of co-location rules.

Abstract: Various techniques are provided for a method including triggering, by a user equipment (UE), a resource block (RB) offset allocation determination, detecting, by the UE, at least one of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) in a received synchronization signal (SS) block (SSB), reading, by the UE, a physical broadcast channel (PBCH) parameter and a signaled offset from a master information block of a PBCH of the SSB, determining, by the UE, an RB offset based on the PBCH parameter and the signaled offset, and determining, by the UE, a control resource set frequency location based on the RB offset.

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). The terminal device may perform a QCL property estimation on received TRSs based on the QCL source configuration.
