Abstract: A apparatus receives a configuration for a phase tracking reference signal (PT-RS). The apparatus then determines at least one of a time density or a frequency density for the PT-RS based on inter-slot repetition of a transmission. The apparatus then receives or transmits the PT-RS based on the at least one of the time density or the frequency density determined based on the inter-slot repetition of the transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information indicating that demodulation reference signal (DMRS) time domain bundling is enabled. The UE may determine a time domain bundling configuration based at least in part on the information indicating that the DMRS time domain bundling is enabled. Accordingly, in some aspects, the UE may perform channel estimation based at least in part on DMRSs received in different physical downlink control channel monitoring occasions based at least in part on the time domain bundling configuration. 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 determine at least one of an interleaving configuration or a cyclic shift configuration for respective repetitions of a control resource set (CORESET). The UE may monitor for one or more physical downlink control channel candidates in the respective repetitions of the CORESET based at least in part on determining the at least one of the interleaving configuration or the cyclic shift configuration for the respective repetitions. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device (such as a user equipment (UE)) may receive from a transmitting device (such as a base station), a configuration of full duplex communication resources for a set of slots. The receiving device may receive a pre-emption indication identifying that at least a portion of the full duplex communication resources in one or more slots of the set of slots is unavailable for communication, and may determine a remaining portion of the full duplex communication resources in the one or more slots based on the received pre-emption indication. The receiving device may then communicate with the transmitting device using the remaining portion of the full duplex communication resources.

Abstract: Aspects relate to mechanisms for measuring the interference on the sidelink for use in calculating the channel quality indicator (CQI) in channel state information (CSI) reporting. Channel state information - interference measurement (CSI-IM) resources on which a sidelink device may measure the interference may be located outside of a bandwidth allocated for the transmission of a physical sidelink shared channel (PSSCH) and/or inside of the allocated bandwidth. The sidelink device may measure respective interference values on one or more CSI-IM resources, identify one or more CQI(s) based on the measured interference value(s) and transmit one or more CSI reports including the one or more CQIs to another sidelink device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to monitor search spaces on a primary cell and an secondary cell in a carrier aggregation configuration. The UE may monitor the search spaces for control information according to a shared search space monitoring configuration. Based on the shared search space monitoring configuration, the UE may identify that the secondary cell is a scheduling cell and the primary cell is a scheduled cell (e.g., cross-carrier scheduling). The UE may monitor control channel candidates of search spaces on the primary cell and on the secondary cell for downlink control information messages scheduling data transmissions with the primary cell. In some examples, the cross-carrier scheduled communications may be configured according to a scheduling configuration, which may include one or more scheduling constraints.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is in communication with a primary cell and a secondary cell in a carrier aggregation configuration, where the primary cell is a cross-carrier scheduled cell and the secondary cell is a cross-carrier scheduling cell. The UE may receive downlink control information from the secondary cell. The downlink control information may include a cross-carrier scheduling indication that a data transmission is scheduled with the primary cell. The UE may monitor a common search space of the primary cell for control information that pertains to communications with the primary cell. The UE may communicate with the primary cell via the data transmission in accordance with at least one of the downlink control information from the secondary cell and the control information from the common search space of the primary cell.
