Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

Abstract: Systems, methods, and apparatuses for sounding reference signal (SRS) management in carrier aggregation (CA) are described. A user equipment (UE) may be scheduled for overlapping (e.g., concurrent) transmissions of SRS and uplink control or data on different cells of a CA configuration. In some cases, the SRS transmission may be dropped (e.g., the UE may refrain from transmitting a scheduled SRS). While in some cases, the UE may transmit both SRS and another uplink message in overlapping time intervals on different cells (e.g., SRS may be transmitted concurrently with another uplink message). A determination of whether to transmit or drop SRS may be based on whether the different cells have different cyclic prefix (CP) lengths or on whether the SRS is scheduled to be transmitted in a special subframe of a time division duplexing (TDD) configuration, for example.

Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for enabling non-destaggered channel estimation. In aspects, a method for wireless communications is provided including determining a first channel impulse response (CIR) based on a first set of received reference signals staggered in time, determining a second CIR based on a second set of received reference signals from the same sub-frame time slot, wherein a reference signal is associated with one of a plurality of virtual transmit antenna ports, and aligning the first CIR and the second CIR based, at least in part, on a time tracking loop (TTL) timing offset.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a first network node (e.g., a user equipment (UE)) receiving first control information indicative of a first feedback scheme for multicast transmissions in a non-terrestrial network (NTN) and determining an applied feedback scheme based on the first feedback scheme. The method may also include the first network node monitoring for a multicast transmission and operating in accordance with the applied feedback scheme.

Abstract: Methods, systems, and devices for wireless communication are described. A network node may transmit a first message using a first transmit power based on a first set of values corresponding to a set of power control parameters. The set of power control parameters may include an accumulated transmit power control parameter. The network node may receive a second message including information indicative of at least one of a second set of values corresponding to the set of power control parameters. The network node may transmit a third message using a second transmit power based on a value corresponding to the accumulated transmit power control parameter. The value may correspond to the accumulated transmit power control parameter, which may be based on a first difference between one or more of the first set of values from before the second message and one or more of the second set of values.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communication device may determine that the wireless communication device is configured to use a primary component carrier (PCC), a first secondary component carrier (SCC), and a second SCC for carrier aggregation. A primary cell may be associated with the PCC, a first secondary cell may be associated with the first SCC, and a second secondary cell may be associated with the second SCC. The first secondary cell may provide control information for the second secondary cell. The wireless communication device may monitor at least one of the first SCC or the second SCC. The wireless communication device may perform an action associated with the second secondary cell based, at least in part, on monitoring the at least one the first SCC or the second SCC.
