Abstract: When a time domain collision between Tracking Reference Signal (TRS) symbols and downlink shared data channel symbols is detected, the TRS symbols may be multiplexed with the downlink shared data channel symbols from multiple Transmission Reception Points (TRPs) not sharing quasi co-location (QCL) parameters with each other. If a time domain collision between TRS symbols and dynamically or semi-static (e.g., persistent) downlink shared data channel transmissions is detected, transmission and/or reception of the TRS and/or the downlink shared data channel may be adjusted.

Abstract: Devices, methods, apparatuses and computer readable storage media of monitoring in beam management with CORESETs associated with CSS and USS. The method includes monitoring a first downlink control channel associated with a first type of CORESET based on a first TCI state; and in accordance with a determination that a first TCI is different from a second TCI state used for the first device to monitor a second downlink control channel associated with a second type of CORESET, determining a reception of a first downlink data channel associated with the first type of CORESET based at least partially on a scheduling offset.

Abstract: Systems. methods. apparatuses. and computer-readable storage mediums are provided for enhancements to physical downlink control channel monitoring for inter-cell scenarios in case of a multiple input multiple output environment. In an example implementation. the method may comprise determining. by a network device of a communication network. to monitor physical downlink control channel candidates in overlapping monitoring occasions of two or more control resource sets of the communication network. wherein the two or more control resource sets are using at least two different QCL-TypeD on an active downlink bandwidth part of one or more cells: and selecting a first control resource set using a first QCL-TypeD and a second control resource set using a second QCL-TypeD for monitoring at least two of the physical downlink control channel candidates, wherein the selection of the first control resource set is based on common search space sets and/or user specific search space sets of at least one control resource set on active downlink bandwidth part of at least one cell that associated with one or more physical cell identifiers, and the selection of the second control resource set is based on user specific search space sets of at least one control resource set on active downlink bandwidth part of at least one cell that associated with at least two physical cell identifiers.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of TRP beam failure recovery. The method comprises determining a set of failed cells associated with the first device based on a beam failure detection; and generating a beam failure report indicating respective one or more failure detection resource sets associated with at least a portion of the set of failed cells. In this way, the UE may determine the information included in the BFR MAC CE in a case where the UL grant is not enough to include all the information for the failed serving cells or the BFR MAC to be transmitted on the MSG3 or MSGA in a CBRA procedure on the SpCell.
