Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may use enhanced techniques for determining whether a transmission is scheduled to include new data when a mode for reporting acknowledgment feedback is disabled for one or more hybrid automatic repeat request (HARQ) processes used by the receiving device. An enhanced technique may include increasing a quantity of bits used to convey an indication of whether a scheduled data transmission includes new data. An enhanced technique may include monitoring a duration between transmissions scheduled by different control messages based on a timing parameter that indicates a maximum time between transmissions of a data set and corresponding transmission including the data set.

Abstract: Aspects of the disclosure relate to communication of power headroom reports in wireless communication networks. A user equipment (UE) may measure a path loss based on a triggering path loss reference signal (PL-RS) and trigger generation of a power headroom report (PHR) based on the path loss. The UE may identify uplink resources for communication of the PHR to a base station and determine whether the uplink resources are quasi-co-located with the triggering PL-RS. When the uplink resources are quasi-co-located with the triggering PL-RS, the user equipment may transmit the PHR utilizing the uplink resources. Otherwise, the UE may generate the PHR such that it includes information identifying the triggering PL-RS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a received physical downlink shared channel (PDSCH) communication is included in multiple downlink association sets, wherein hybrid automatic repeat request acknowledgement (HARQ-ACK) information for different downlink association sets is to be reported in different slots; report a valid HARQ-ACK in a first slot indicated by a PDSCH-to-HARQ feedback timing value associated with the PDSCH communication; and selectively report the valid HARQ-ACK, corresponding to the PDSCH communication, or a negative acknowledgement (NACK) in a second slot based at least in part on whether the second slot occurs before or after the first slot, wherein the second slot is to be used for reporting HARQ-ACK information associated with a downlink association set of the multiple downlink association sets. Numerous other aspects are provided.
