Abstract: A method, apparatus, and computer-readable medium are provided that improves power savings and reliability of communication for DRX/eDRX modes. A base station may receive an indication from a network entity that a UE is in a DRX/eDRX mode. The base station may configure a WUS mode for the UE corresponding to the DRX mode or the eDRX mode. A UE may receive the WUS mode from the base station. When a UE is configured for relaxed RRM measurements for a first cell and moves to a second cell that supports a relaxed RRM measurement, the UE may return to a regular RRM measurement for a time period. When a UE configured for a WUS mode for a first cell moves to a second cell that supports the WUS mode, the UE may return to the DRX mode or the eDRX mode without the WUS mode for a period of time.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives one or more downlink signals using a first beam associated with a first set of frequency resources, switches from the first beam to a second beam associated with a second set of frequency resources, selects a set of frequency resources for transmitting feedback information associated with the one or more downlink signals, and transmits the feedback information to the base station using the selected set of frequency resources. In some examples, the UE transmits one or more uplink signals to a base station using a first beam associated with a first set of frequency resources, switches from the first beam to a second beam associated with a second set of frequency resources, and determines whether to send a retransmission of the one or more uplink signals based at least in part on switching.

Abstract: The apparatus wireless communication may include a UE. The UE may receive a DL communication triggering a UL communication starting in a first UL slot/subframe from an NTN BS over at least one DL slot/subframe ending in a first DL slot/subframe. The UE may monitor for DL communications from the NTN BS in at least a subset of DL slots/subframes between the first DL slot/subframe and a second DL slot/subframe that is time-aligned with the first UL slot/subframe. The DL communication may trigger a second DL communication starting at a third DL slot/subframe and ending at a fourth DL slot/subframe, and the UL communication is based at least in part on receiving the second DL communication, and the UE may monitor the at least the subset of slots/subframes between the fourth DL slot/subframe and the second DL slot/subframe.

Abstract: Methods, systems, and devices for wireless communications are described. A set of uplink control channel resources that are configured for acknowledgment transmissions may be shared among user equipments (UEs) that are enabled to receive multicast communications. Each of the shared set of uplink control channel resources may be associated with set(s) of channel state information. UEs may measure a multicast channel to determine channel state information for the multicast channel. After failing to receive a multicast transmission, UEs may transmit an acknowledgment feedback message over one of the shared uplink control channel resources that is associated with the set of channel state information determined by the UE. A base station that receives the acknowledgment feedback message may transmit a multicast retransmission for the UEs using transmission parameters that are adapted for the set(s) of channel state information associated with the occupied uplink control channel resource.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an autonomous uplink (AUL) transmission to a base station using a configured resource set, the AUL transmission comprising reference signals and data signals. The UE may determine whether a response signal was received from the base station in response to the AUL transmission. The UE may determine whether the response signal indicates that the base station received the reference signals, or the reference signals and the data signals. The UE may select an uplink transmission scheme to use for subsequent transmissions to the base station, the selected uplink transmission scheme based at least in part on the determination of whether the response signal was received from the base station and whether the response signal indicates that the base station received the reference signals or the reference signals and the data signals.

Abstract: Techniques for reference signaling related to transmission power controls for communication devices are discussed and provided. A user equipment (UE) receives one or more sounding reference signal (SRS) transmission power control (TPC) configuration for uplink carriers. The SRS TPC configuration can comprise a mapping from one uplink carrier to one or more component carrier sets. The UE receives, from a monitoring cell, a downlink control information (DCI) comprising a request for SRS transmission on uplink carrier(s) and/or TPC command(s) for SRS transmission on the uplink carrier(s). The UE determines uplink carrier(s) corresponding to the SRS request and/or the TPC command(s) at least based on a correspondence between the SRS TPC configurations and the one or more uplink carriers or based on starting bit information.
