摘要： Techniques of performing CSI reporting include identifying a cluster of TRPs sharing common information in their CSI and transmitting a complete CSI report to a selected TRP of the cluster while transmitting partial CSIs reports to other TRPs of the cluster. Along these lines, in an example implementation, a UE receives a CSI-RS from a network, with the CSI-RS carrying a plurality of reference symbols from a plurality of TRPs. Based on the plurality of symbols, the UE generates TRP data representing CSI feedback for each of the TRPs. From the CSI feedback, the UE identifies, as a cluster, a subset of the TRPs that share common information within the CSI feedback. The UE then sends first identification data identifying the subset of the TRPs that make up the cluster to the network.

摘要： According to an example aspect of the present invention, there is provided an apparatus, such as a user equipment, configured to transmit information in a physical uplink shared channel direction using, selectably, a first waveform or a second waveform, the second waveform having lower peak to average power ratio than the first waveform, provide, to a network node controlling a cell in which the apparatus is attached, first and second power headroom information, and select to either continue using the first waveform on the physical uplink shared channel, or to switch to using the second waveform on the physical uplink shared channel.

摘要： According to one example embodiment, a method may include receiving, by a user equipment, at least one network entity failure indication configuration. The method may further include detecting, by the user equipment, that at least one first network entity satisfies at least one beam-failure condition. The method may further include selecting, by the user equipment, one or more of at least one resource and at least one parameter based on the at least one received network entity failure indication configuration. The method may further include transmitting, by the user equipment, the at least one indication of the at least one first network entity that satisfies the at least one beam-failure condition to at least one second network entity.

摘要： Various communication systems may benefit from an improved resource block group allocation in a cell. A method may include determining at a network entity a common frequency resource allocation grid in a cell. The method may also include configuring at the network entity a frequency location of a bandwidth part of a user equipment within the cell. The frequency location of the bandwidth part may be offset from a reference point of the common frequency resource allocation grid. In addition, the method may include determining a size of one or more of a plurality of resource block groups within the bandwidth part of the user equipment based on the frequency location of the bandwidth part and the reference point. Further, the method may include transmit downlink control information from the network entity to the user equipment.

摘要： Systems, methods, apparatuses, and computer program products relating to phase tracking reference signal (PT-RS) design, for example, for discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM), are provided. One method may include forming, by a network node, a phase tracking reference signal (PT-RS) sample sequence using outer-most constellation points corresponding to scheduled modulation order of data channel, and scrambling the phase tracking reference signal (PT-RS) sample sequence with a user equipment-specific sequence.

摘要： Systems, methods, apparatuses, and computer program products for channel state information (CSI) configuration and reporting for multi-transmission reception point (TRP) operation are provided. One method may include configuring a user equipment (UE), by a network node, to provide independent channel state information (CSI) feedback per transmission reception point (TRP) and to indicate additional information. The configuring of the UE may include configuring the UE with at least one of several reporting options for generating a combined channel state information (CSI) report.
