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: Signaling is received (or transmitted) to configure a UE with multiple transmit beams, each for receiving beam-specific DCI. A beam-specific current DCI is received at the UE (or transmitted from a network) on the transmit beam(s), including information about beam-specific previous DCIs transmitted to the UE on any of the multiple transmit beams within a predefined time window preceding a time unit in which the current DCI was received. Information about the beam-specific previous DCIs is used to determine that at least one of the multiple transmit beams has been blocked. Each of the multiple transmit beams that have been determined to be blocked is reported to (and received by) the network. In response to receiving from the UE a report indicating at least one multiple transmit beams has been blocked, the network reconfigures the UE with a different set of multiple transmit beams each for beam-specific DCI.

Abstract: At a UE, a rank indication is determined for multi-rank CSI feedback for a subband. The UE selects one of multiple combinations of first and second offset levels for the subband to indicate the determined rank indication. Each offset level is for one of two different codewords and denotes an offset between an MCS class reported in a subband CQI and an MCS class in a wideband CQI. The UE transmits one or more indications of the first and second offset levels. A base station receives the one or more indications, and determines the rank indication based on the one or more indications of the first and second offset levels. The base station schedules, based on the determined rank indication, data for transmission to the user equipment using one or multiple ranks.
