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 a first uplink slot on an uplink carrier for reporting channel state information. The UE determines, on a downlink carrier, a first downlink slot that is an earliest downlink slot overlaps with the first uplink slot. The UE determines a number M based on a numerology of the downlink carrier, M being an integer greater than or equal to 0. The UE measures a reference signal, received no later than a second downlink slot that is a latest valid downlink slot no later than M downlink slots prior to the first downlink slot, to generate the channel state information.

Abstract: Examples pertaining to repeater gain control for device collaboration in distributed MIMO systems are described. An apparatus (e.g., a repeater) may determine a first compensation value for a first path loss on a first link between the apparatus and a UE, and determine a second compensation value for a second path loss on a second link between the apparatus and a network node of a wireless network. The apparatus may also determine a repeater gain for uplink power control according to the first compensation value and the second compensation value. The apparatus may further forward a radio signal from the UE to the network node according to the repeater gain.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and a wireless system including a wireless device and a UE are provided. The UE transmits, on first RF time-frequency resources, first RF signals carrying user data to be sent to a base station. The wireless device receives the first RF signals on the first RF time-frequency resources. The wireless device transmits, to the base station, second RF signals on second RF time-frequency resources. The second RF signals carries the user data.

Abstract: Apparatus and method for assistance information transmission and CSI reporting are proposed. The network node may allocate channel state information (CSI) configuration for the UE and transmit the CSI configuration to the UE. The UE may perform CSI measurement based on the CSI configuration from the network node, determine the assistance information based on the CSI measurement result, and transmit the assistance information the network node to improve the downlink (DL) throughput and save the signaling overhead of CSI measurement or CSI reporting.

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: 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: Apparatus and methods are provided multiple transmission. In one novel aspect, TCI-state indication for non-coherent joint transmission (NCJT) channel station information (CSI) reporting is provided. The UE receives NCJT from at least a first transmission from a first transmission point (TRP) and a second transmission from a second TRP, determines a receiving (RX) spatial filter information for the NCJT and acquires channel state information (CSI) according to a report setting based on the determined RX spatial filter to simultaneously acquire at least two channel measurement resources (CMRs) and one interference measurement resource (IMR), wherein at least one CMR is from the first TRP and at least one CMR is from the second TRP. In one embodiment, the RX spatial filter information is determined based on a group-based beam reporting procedure performed by the UE. In another embodiment, the RX spatial filter information is determined based on TCI-state received from the wireless network.

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 a first trigger. The UE determines, based on the first trigger, whether it is possible that a first transmission and reception point (TRP) and a second TRP are to transmit a first down link control channel and a second down link control channel to the UE concurrently on a carrier. The UE monitors the first down link control channel and the second down link control channel in a particular slot when it is possible that the first TRP and the second TRP are to transmit the first down link control channel and the second down link control channel to the UE concurrently on the carrier.

Abstract: Techniques and examples pertaining to linear combination codebook design and channel state information (CSI) feedback in mobile communications are described. Frequency-dependent parameterization is supported to reduce signaling overhead in reporting beam selection and to enhance CSI resolution. Additionally, the number of candidates for beam selection depends on the strength of each beam to be selected such that more candidates are considered for a stronger beam than for a weaker beam. Moreover, amplitude quantization and/or phase quantization for beams of different strengths are different to reduce quantization error.
