Abstract: A UE determines N1 component carriers on each of which the UE is configured to detect a respective one PDCCH in a slot. The UE determines N2 component carriers on each of which the UE is configured to detect respective at least two PDCCHs in the slot. The UE determines a total Q blind detections of PDCCH that the UE is capable of performing. The UE determines a first predetermined scaling factor X. The UE allocates M1 blind detections of the Q blind detections to be available on each of the N1 component carriers and M2 blind detections of the Q blind detections to be available on each of the N2 component carriers such that (N1*M1+N2*M2) is a largest integer no greater than Q. M2 equals to X*M1. The UE performs blind detections in accordance with the allocations.

Abstract: In one novel aspect, multiple TRPs information are provided for REG bundle configuration with PDCCH transmission and reception with multiple transmission points (TRPs). The UE configures a PDCCH associated with a CORESET comprising multiple CCEs, partitions the CORESET into multiple CCE groups associated with corresponding TCI-state, which corresponds to a source TRP, configures multiple resource element group (REG) bundles each with multiple resource elements (REs), and assumes the same precoder applied on PDCCH DMRS when the REs are in the same REG bundle and are associated with the same source TRP, and wherein each source TRP transmits corresponding portion of DCI data mapping to the corresponding first and second CCE group. In one embodiment, the REG bundles are predefined with each comprises only REs associated with the same source TRP. In another embodiment, each CCE group corresponding to a source TRP is indicated for the REG bundle configurations.

Abstract: Various examples with respect to frequency-selective precoding for uplink (UL) transmissions in mobile communications are described. A processor of a user equipment (UE) receives signaling from a network node of a wireless network. The processor then performs a codebook-based UL transmission to the network node with frequency-selective precoding in a subband of a plurality of subbands according to the signaling received from the network. For non-codebook-based UL transmissions, the processor performs a non-codebook-based UL transmission of a beamformed sounding reference signal (SRS) to the network node by determining a precoder and performing frequency-selective precoding on the SRS using the precoder with a size of precoder bundling for the frequency-selective precoding in a frequency domain known by the network node.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, a trigger for reporting M CSI reports. M is an integer greater than 0. The UE determines a wait time period from a reference point to a time point at which N CSI reports of the M CSI reports are to be transmitted. N is an integer greater than 0 and smaller than or equal to M. The UE determines N respective processing time periods for updating the N CSI reports. The UE determines a maximum processing time period that is the largest among the N respective processing time periods. The UE further determines whether to update the N CSI reports based on the maximum processing time period and the wait time period.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines to report CSI reports. The UE determines that a first CSI report and a second CSI report to be reported contain same CSI information. The UE determines that total processing units required for updating the first CSI report and the second CSI report to be processing units required for updating one of the first CSI report and the second CSI report. The UE updates the first CSI report and the second CSI report based on a same CSI calculation.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines first one or more symbol periods in a slot and in which a first set of Demodulation Reference Signals (DMRSs) transmitted from a first transmission reception point (TRP) is carried on a first set of resource elements. The UE demodulates modulation symbols of a first data channel carried on part of or all remaining resource elements in the first one or more symbol periods of the slot other than the first set of resource elements when the remaining resource elements are not allocated to carry DMRSs.
