Abstract: Disclosed are techniques for wireless communication. In an aspect, a BS transmits, to a UE, a DCI that triggers an AP-CSI-RS on symbol(s) that are less than a beam switch timing threshold from the DCI. The UE and BS select one or more TCI states for reception of the AP-CSI-RS at the UE based at least in part on whether or not one or more overlapping downlink signals associated with the CORESET pool index are scheduled on the one or more symbols. The BS transmits the AP-CSI-RS, and the UE measures the AP-CSI-RS via the one or more TCI states in accordance with the TCI state selection.

Abstract: Certain aspects of the present disclosure provide techniques for quasi-colocation (QCL) assumption for an aperiodic channel state information (A-CSI) reference signal (RS) configured with multiple transmission reception point (mTRP). A user equipment (UE) may receive signaling configuring the UE with a plurality of index values associated with different control resource sets (CORESETS). The UE may receive, from a base station (BS), first downlink control information (DCI) triggering an A-CSI-RS resource set for A-CSI reporting. The first DCI is received in a first CORESET of the different CORESETs associated with a first index value of the plurality of index values. The UE may determine a first time offset between the first DCI and the A-CSI-RS resource set. When the first time offset is smaller than a threshold time offset, the UE may determine a QCL assumption for receiving the A-CSI-RS based, at least in part, on the first index value.

A method of wireless communication performed by a user equipment (UE) and a UE is disclosed. The method includes determining a beam failure configuration for a serving cell, the beam failure configuration including at least one of a beam failure parameter of a beam group or a beam failure parameter of a cell; and detecting, in the serving cell based at least in part on the beam failure configuration, a beam failure recovery (BFR) based at least in part on the beam failure configuration. The beam failure configuration is determined based on various rules that control the operation of the BFR.

Abstract: A phase tracking reference signal (PT-RS) may be transmitted to enable a receiver to correct phase noise in wireless communication. A UE scheduled for one PDSCH with DMRS ports in two or more DMRS CDM groups that are associated with two TCI states may be configured for PT-RS using two PT-RS ports. Therefore, rather than limiting PT-RS to a single port, the PT-RS may be transmitted to the UE using two PT-RS ports. The apparatus transmits a capability indication for more than one PT-RS port for receiving a downlink shared channel based on a first TCI and a second TCI. The apparatus receives a configuration for a maximum number of downlink PT-RS ports from a base station.

Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a message to a transmission reception point (TRP) in a multi-TRP network that indicates a capability of the UE to support a communication scheme (e.g., a spatial division multiplexing (SDM) scheme, a single frequency network (SFN) scheme, a combined SDM and SFN scheme, or the like). The UE may receive a configuration that indicates parameters common to both the SDM scheme and the SFN scheme. The TRP may transmit an indication of an SDM scheme, an SFN scheme, a combined SDM and SFN scheme, or the like to the UE for communications between the UE and one or more TRPs. The UE may communicate with the one or more TRPs based on the communication scheme indicated by the TRP.

Abstract: A UE configured to report resources, such as beams, to a base station may be unaware of the context or purpose for which the UE is reporting such resources. As different resources may provide different performance and/or quality when used in different contexts, the resources reported by the UE may provide lower quality and/or performance in one context relative to some other unreported resources. In order to improve resource reporting by the UE, the UE may be informed of an operational mode and/or a criteria based upon which the UE may select resources to report. The UE may report such selected resources to the base station in a group-based beam report. The base station may then configure communication with the UE based on the reported resources.

Abstract: Since multiple transmit-receive point (TRP) communications may increase the number of physical downlink control channel (PDCCH) candidates without increasing the number of cells, new limits for multi-TRP communications may be defined. A UE may determine a PDCCH monitoring capability across all downlink serving cells that may account for multiple-TRP cells and for carrier aggregation and dual connectivity using a multiplication factor for serving cells with two control resource set (CORESET) groups, for signaling a number representing PDCCH monitoring capability across all downlink serving cells. Further, the UE may determine limits of a number of serving cells based on the capability and a configuration of serving cells. The UE may determine a total limit and a per cell limit of PDCCH candidates and non-overlapped control channel elements (CCEs) to monitor in a slot for a cell group. The UE may perform blind decoding operations within the limits.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may provide hybrid automatic repeat request (HARQ) feedback for multiple physical channels (e.g., multiple physical downlink shared channels (PDSCH)) scheduled via multi-component carrier. The UE may monitor control channel occasions (e.g., physical downlink control channel (PDCCH) occasions), to receive wireless communications from a base station (e.g., a next-generation NodeBs (gNB)). For example, the UE may receive multiple downlink control information (DCI) messages that may schedule multiple PDSCH over different component carriers. The UE may identify one or multiple downlink assignment indices (DAI) in the received DCI messages. In some examples, the UE may generate one or more feedback bits of a HARQ feedback codebook (also referred to as an acknowledgement codebook). The one or more feedback bits include a same number of feedback bits for each downlink assignment index associated with each DCI message.

The UE may transmit an SRS using an SRS resource associated with the first SRS resource set based at least in part on the first group being activated and the first group being included in the first one or more groups. Numerous other aspects are provided.
