Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a position (e.g., a global navigation satellite system (GNSS)) position of the UE based on a relative position of the UE to another UE. For example, a first UE may determine (e.g., calculate, receive) a relative position of the first UE to a second UE that is selected from a set of UEs including the first UE and the second UE to perform a position acquisition procedure to determine a position of the second UE. The first UE may determine (e.g., calculate, receive) its position based on the relative position of the first UE to the second UE and the position of the second UE and may reset a timer that indicates for the first UE to perform a position acquisition procedure upon expiration of the timer.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently retransmitting radio link control (RLC) protocol data units (PDUs) to one or more UEs. When a user equipment (UE) fails to receive or decode an RLC PDU transmitted by a base station, the UE may transmit a status PDU to the base station indicating that the UE failed to receive or decode the RLC PDU. The base station may receive the status PDU from the UE, and the base station may generate a repair PDU that includes redundant bits of the lost PDU (e.g., the PDU that the UE failed to receive or decode). The base station may then transmit the repair PDU to the UE, and the UE may use the redundant bits in the repair PDU (e.g., in combination with buffered PDUs) to attempt to correctly decode the lost PDU.

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.
