Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a base station, a configuration associated with a layer to reference signal port mapping. In some cases, the UE may identify, based at least in part on the configuration, that at least one layer of a set of layers for receiving a downlink transmission from the base station is adapted based on at least one interference layer. In some cases, the adapted layer may be mapped to one or more reference signal ports. The UE may receive the downlink transmission and may decode the downlink transmission based on identifying that the at least one layer is adapted and the layer to reference signal port mapping.

Abstract: Disclosed are techniques related to wireless communications. In an aspect, a network entity determines whether a source reference signal transmitted from a first transmission-reception point (TRP) is a quasi-collocation (QCL) source of a target reference signal transmitted from a second TRP based, at least in part, on a first bandwidth (BW) portion occupied by the source reference signal and a second BW portion occupied by the target reference signal, the first BW portion having a first start frequency and a first BW size and the second BW portion having a second start frequency and a second BW size, and configures a user equipment (UE) with the source reference signal as the QCL source of the target reference signal when it is so determined.

Abstract: Certain aspects of the present disclosure relate to uplink preemption in certain systems, such as new radio (NR) systems, supporting carrier aggregation (CA) and/or multi-connectivity modes. A method for wireless communication, that can be performed by a user equipment (UE), generally includes receiving a resource assignment scheduling the UE for uplink transmission. The UE receives an indication to preempt uplink transmission on a portion of the assigned resources and determines whether to transmit on the remaining assigned resources. A method that can be performed by a base station (BS) generally includes receiving an indication from one or more UEs indicating, for each of a plurality of band combinations, a capability of the UE to transmit on a band when transmission on another band in the band combination is preempted and scheduling the one or more UEs for uplink transmission based on the indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication of whether the UE is capable of using a virtual port to transmit uplink communications using a maximum transmit power according to a power class of the UE. The virtual port may be a combination of one or more antenna ports. The indication may be based at least in part on an operating mode of the UE. The UE may receive, from the base station, a sounding reference signal configuration based at least in part on the indication. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify multiple channel state information (CSI) reports scheduled to be transmitted in a slot on respective physical uplink control channel (PUCCH) resources. For example, the multiple CSI reports may include one or more CSI reports associated with a first service type and one or more CSI reports associated with a second service type. The UE may select, from the multiple CSI reports, one or more CSI reports to be transmitted in the slot based at least in part on a first priority associated with the first service type and a second priority associated with the second service type. Accordingly, the UE may transmit, in the slot, one or more PUCCH transmissions that include the one or more selected CSI reports. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment determine that a physical uplink shared channel (PUSCH) communication, scheduled by an uplink grant, and a physical uplink control channel (PUCCH) communication, corresponding to a physical downlink shared channel (PDSCH) communication scheduled by a downlink grant, are scheduled to overlap in one or more symbols; determine a threshold time based at least in part on an earliest scheduled starting time of the PUSCH communication or the PUCCH communication; selectively multiplex the PUSCH communication and the PUCCH communication based at least in part on whether the uplink grant, the downlink grant, and the PDSCH communication are received before the threshold time; and transmit the PUSCH communication, the PUCCH communication, or both the PUSCH communication and the PUCCH communication based at least in part on the selective multiplexing. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus methods and apparatus for multiplexing demodulation reference signals (DMRS) and synchronization signals (SS) in new radio (NR). An exemplary method that may be performed by a base station (BS) includes determining transmission resources, in a set of slots, to be used for first demodulation reference signals (DMRS), based on whether synchronization signals (SS) are to be transmitted in the set of slots, and transmitting the first DMRS using the transmission resources in the set of slots.
