Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate, to a base station, a capability of the UE to use a channel measurement resource for both a joint transmission hypothesis and a single transmission hypothesis. The UE may receive, based on indicating the capability of the UE, a configuration message indicating a first channel measurement resource that is associated with a first transmission configuration indicator state and that is configured for a first joint transmission hypothesis. The UE may obtain a channel measurement for both the first joint transmission hypothesis and a first single transmission hypothesis using the first channel measurement resource based on the configuration message.

Abstract: This disclosure provides systems, methods and apparatus for channel state information reference signal (CSI-RS) resource activation or deactivation within a resource set. In one aspect, a base station (BS) may transmit control signaling to a user equipment (UE) including an indication to switch an activity status of one or more CSI measurement resources within a CSI resource set from an activated state or a deactivated state to the other. The control signaling may include a bitmap indication for the activity status for the one or more CSI measurement resources or a CSI measurement resource identifier for each CSI measurement resource in an activated state. The UE may transmit a CSI report including information from measuring a channel state, a channel interference, or both for the one or more CSI measurement resources based on the activity status of each.

Abstract: Certain example embodiments of the present disclosure provide techniques for joint transmission of channel state information reference signals (CSI-RS) from multiple transmission points (TPs) for channel state feedback and/or TP selection. An example method generally includes coordinating with one or more other TPs to jointly transmit a channel state information reference signal (CSI-RS) to a user equipment (UE); signaling a reporting restriction to the UE; receiving precoding matrix indicator (PMI) feedback from the UE based on the jointly transmitted CSI-RS and subject to the reporting restriction; and selecting one or more of the TPs to serve based on the PMI feedback.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information associated with a secondary cell (SCell), wherein the SCell has a narrowband channel bandwidth. The UE may receive a synchronization signal block (SSB) on the SCell in accordance with an SSB bandwidth configuration, wherein the SSB bandwidth configuration is associated with at least one of: the configuration information, or a frequency of the SSB being identified by a synchronization raster, wherein the synchronization raster is for cells having the narrowband channel bandwidth. The UE may monitor an initial control resource set (CORESET) using a CORESET bandwidth configuration associated with the configuration information. Numerous other aspects are described.

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: This disclosure provides systems, methods and apparatus for wireless communications. In one aspect, a device, such as a user equipment (UE) may receive a configuration including one or more channel state information (CSI) measurement resources associated with a set of CSI hypotheses. The set of CSI hypotheses may correspond to a set of transmission configuration indicator (TCI) states, or a CSI interference measurement (CSIIM) resource, or both. The UE may select a first CSI measurement resource of the one or more CSI measurement resources for a channel measurement based on a CSI hypothesis of the set of CSI hypotheses. The UE also may select the CSIIM resource or a second CSI measurement resource for an interference measurement based on the CSI hypothesis of the set of CSI hypotheses. The UE may, as a result, transmit a report based on the channel measurement or the interference measurement, or both.

Abstract: Certain aspects of the present disclosure provide techniques for determining an energy per resource element (EPRE) ratio for non-zero power (NZP) channel state information reference signals (CSI-RSs) when a device is measuring a wireless channel. A method that may be performed by a user equipment (UE) includes determining, based on an indication, an energy per resource element (EPRE) ratio for a non-zero power (NZP) channel state information reference signal (CSI-RS) resource; and measuring a channel based on the determined EPRE ratio and CSI-RS s associated with the NZP CSI-RS resource.
