Abstract: Various aspects of the present disclosure generally relate to wireless communication. A UE capability for a multiple physical downlink shared channel (PDSCH) scheduling may be signaled from a UE to a network entity. A UE capability signaling may indicate whether the UE supports a multiple PDSCH scheduling being associated with a same time domain resource allocation (TDRA) and/or a same frequency domain resource allocation (FDRA). The network node may schedule the multiple PDSCHs, via a multiple user multiple-input multiple-output (MU-MIMO) PDSCH scheduling or a multiple downlink control information (multi-DCI) multiple transmission reception point (mTRP) PDSCH scheduling, based at least in part on the UE capability signaling. The network entity may guarantee that co-scheduled PDSCHs have the same TDRA and/or the same FDRA, which may be based at least in part on the UE capability signaling.

Abstract: Method and apparatus for control signaling for SIC operation in 2-codeword operating mode. The apparatus transmits, to a network entity, a SIC capability indication comprising an indication that the UE supports a SIC operation for 2-CW allocation and an order of processing a first codeword and a second codeword. The apparatus monitors for an ACK to enable the SIC operation between the UE and the network entity. The apparatus receives downlink communication based on the SIC operation in response to receiving the ACK to enable the SIC operation. The apparatus may process the first codeword, within the downlink communication, transmitted based on a first MCS. The apparatus may cancel interference from the downlink communication based on the first codeword to obtain the second codeword, within the downlink communication, transmitted based on a second MCS.

Abstract: Aspects described herein relate to receiving, from a network node, an indication of information related to a configuration, including at least one of a modulation and coding scheme (MCS), a physical downlink shared channel (PDSCH) duration, a scrambling sequence, or a reference signal location, used for transmitting downlink signals to one or more co-scheduled UEs, receiving, from the network node, a downlink signal intended for the UE, wherein the signal is interfered by one or more interference signals transmitted to the one or more co-scheduled UEs, and removing, based on the indication, the one or more interference signals from the downlink signal. Other aspects relate to transmitting the information and downlink signals.

Abstract: A method for wireless communication by a network node includes transmitting a first group of frames comprising a group of normal slots and one or more first special slots. The method also includes reconfiguring one or more second special slots within a second group of frames scheduled after the first group of frames based on a block error rate (BLER) associated with the group of normal slots failing to satisfy a BLER condition. The method further includes transmitting the second group of frames based on reconfiguring the one or more second special slots within the second group of frames.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a message that includes an indication that a transmission configuration indicator (TCI) state switch for the UE is to be across a serving remote radio head (RRH) and a next RRH.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus maybe a base station or a UE. In an aspect, the apparatus may determine locations for a number of DM-RS symbols to be transmitted in a scheduling unit of a channel configured in a slot/mini-slot, where a last DM-RS symbol maybe positioned one symbol prior to a last symbol carrying scheduled data. In another aspect, the apparatus may determine the locations for the DM-RS symbols based on a selection between a first set of predetermined DM-RS positions and a second set of predetermined DM-RS positions. In another aspect, the apparatus may determine the locations for the DM-RS symbols based on a set number of symbols, wherein the determined locations are spaced apart according to the set number of symbols. The apparatus may transmit the DM-RS symbols based on the determined locations.
