Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may receive, from a base station, a physical downlink control channel (PDCCH) indicating a configuration for one or more of demodulation reference signal (DMRS) bundling that is to be used for channel estimation by the base station for a first group of physical uplink control channels (PUCCHs) or frequency hopping for a second group of PUCCHs. The apparatus may transmit, to the base station, one or more PUCCHs based at least in part on the configuration. Numerous other aspects are described.

Abstract: Certain aspects provide enhancements to enable per transmission reception point (per-TRP) based beam failure recovery (BFR), and more particularly, techniques for configuring physical uplink control channel (PUCCH) BFR for TRP specific BFR. A method that may be performed by a user equipment (UE) includes communicating with at least two TRPs using beams associated with at least two beam groups, each of the beams groups associated with one of the TRPs, detecting a beam failure in a beam group of the at least two beam groups, transmitting a beam group specific BFR scheduling request (SR), in accordance with one or more rules, for an uplink (UL) grant to transmit a beam failure recovery request (BFRQ) specific to the beam group in which the beam failure was detected, receiving the UL grant in response to the SR, and transmitting the BFRQ specific to the beam group based on the UL grant.

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: Methods, systems, and devices for wireless communications are described. A device may identify a transport block (TB) size for a TB that is scheduled across a set of component carriers (CCs) including a first CC and a second CC. The TB may include a first code block (CB) and a second CB. The device may rate match the TB with the set of CCs. Based on the rate matching, the device may identify redundancy portions of the first CB and redundancy portions of the second CB. The device may allocate a first redundancy portion of the first CB and a first redundancy portion of the second CB to the first CC, and may allocate a second redundancy portion of the first CB and a second redundancy portion of the second CB to the second CC. The device may transmit the TB over the set of CCs based on the allocating.

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.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE). The apparatus receives configuration information for a sounding reference signal (SRS) transmission with one or more transmission reception points (TRPs), the configuration information assigning a comb value of greater than 4. The apparatus transmits, to the one or more TRPs, the SRS transmission using one of every N resource elements over a span of one or more resource blocks during a slot, where N is greater than 4.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE) may support repetition of physical downlink control channels (PDCCH) and handling a combined PDCCH candidate associated with multiple search space sets. For example, a UE may combine a first PDCCH candidate corresponding to a first search space set and a second PDCCH candidate corresponding to a second search space set to form a combined PDCCH candidate. The UE may decode the combined PDCCH candidate based on one or more factors, for example, such as a blind decoding PDCCH candidate threshold. As a result, the UE may decode the combined PDCCH candidate in addition to decoding of individual PDCCH candidates, thereby providing increased flexibility for downlink control information (DCI) and improving the reliability of PDCCH.

Abstract: Methods, systems, and devices for wireless communication are described to indicate a transmission scheme configuration for a message and whether the message is a retransmission or new transmission. In a first example, a base station may configure a subset of one or more feedback process identifiers (IDs) for multicast messages. In such cases, if a grant includes a feedback process ID associated with one of the reserved IDs, the message scheduled by the grant may be a retransmission of a multicast message. In a second example, feedback process IDs may be dynamically allocated to multicast or unicast messages via a corresponding grant. A message may be identified as a new transmission or retransmission of a unicast message or multicast message based on a combination of an ID associated with the grant and a new data indicator (NDI) of the grant.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect an occurrence of a triggering event associated with power headroom reporting. The UE may transmit, from the UE to a base station, a power headroom report (PHR) medium access control (MAC) control element (CE) based at least in part on the occurrence of the triggering event, wherein the PHR MAC-CE is for one or more uplink component carriers of the UE that are associated with one or more control resource set pool index values. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a network entity configuring a virtual cell group with multiple cells, where each cell may have a radio frequency spectrum band with a frequency gap that exceeds an operating band threshold. The network entity may transmit additional control signaling including information for the virtual cell group. In some cases, the additional control signaling may include resource allocation information for the virtual cell group, such that the UE may communicate multiple shared channels via different cells in the virtual cell group using the resources indicated in the resource allocation information. In some other cases, the additional control signaling may include a cancellation indication for the virtual cell group, such that the UE may refrain from communicating signals using one or more cells of the virtual cell group.
