Abstract: Methods, systems, and devices for wireless communications are described that support techniques for intra-satellite handover. The described techniques provide for handovers such that a user equipment (UE) may transition from communications with a satellite via a first frequency (or set of frequencies) to communications with the same satellite via a second frequency (or set of frequencies). A UE may determine relevant timing and/or configuration for the second frequency (or set of frequencies) prior to transitioning from communications via the first frequency (or set of frequencies). Thus, the UE may efficiently begin communications at a second frequency (or set of frequencies) that are different than the first frequency (or set of frequencies)—for example, without performing a random access procedure.

Abstract: Methods, systems, and devices for wireless communication are described. The method may include an energy harvesting (EH) device receiving a first control signal that includes scheduling information for the EH device. The scheduling information may indicate a first set of resources for communicating a first signal and a first offset between receiving the first control signal and communicating the first signal. Further, the method may include transmitting, via a second set of resources, a second signal indicating a second offset between receiving the first control signal and communicating the first signal and communicating the first signal via the first set of resources based on the second offset.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive a communication from a second UE. The UE may transmit, to the second UE, sidelink hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a sidelink component carrier based at least in part on the communication received from the second UE, wherein the sidelink component carrier is associated with conveying the sidelink HARQ-ACK feedback when sidelink carrier aggregation is configured for a group of UEs that includes the first UE and the second UE. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for time division multiplexing (TDMing) user equipment (UE) data using guard interval (GI)-based waveforms. An example method generally includes communicating with a device using a frame format, the frame format comprising a first symbol, a second symbol, and a third symbol, wherein: the first symbol comprises a first data portion for a first UE and a first GI corresponding to the first UE; the third symbol comprises a second data portion for a second UE and a second GI corresponding to the second UE, wherein the third symbol is later in time than the first symbol; and the second symbol comprises a gap or a reference signal (RS), a third GI corresponding to the first UE, and a fourth GI corresponding to the second UE, wherein the second symbol is between the first and third symbol in time.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a network entity to indicate one or more wake-up radio (WUR) configurations to a user equipment (UE), which may communicate a desired WUR configuration with the network entity. The UE may indicate a request for the desired WUR configuration, may multiplex the request with another signal associated with the UE, or both. Additionally, or alternatively, the network entity may indicate a single WUR configuration to the UE, which may be determined according to desired configurations, a class of WUR, or both associated with a group of UEs including the UE. Such techniques may support a reduced overall power expenditure of the UE by improving WUR operation.

Abstract: Methods, systems, and devices for wireless communications are described that provide for group or one-shot acknowledgment (ACK) feedback reporting, in which feedback for a number of different downlink transmissions may be provided by a user equipment (UE) to a base station. A base station may trigger a one-shot feedback report that includes less than all of the ACK feedback that is available at the UE to provide in a report. The ACK feedback may include an indication of an ACK or a negative acknowledgement (NACK) along with information related to a data indicator associated with the downlink transmission. In some cases regular ACK feedback reports and one-shot feedback reports may be multiplexed and transmitted by a UE. Further, a last downlink transmission to be included in a one-shot feedback report may be determined based on a receipt time of scheduling information or an ACK feedback timeline.

Abstract: Certain aspects of the present disclosure provide techniques for determining priority information associated with hybrid automatic repeat request (HARQ) feedbacks for wireless nodes in sidelink communications. A subset of the HARQ feedbacks are selected based on the priority information. The selected HARQ feedbacks are then transmitted to the second wireless nodes.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to transmit one or more reference signals to a second wireless device using a first antenna array at the first wireless device and in accordance with a first precoder matrix. The first wireless device may receive, from the second wireless device based on the one or more reference signals, a feedback message indicating an estimated rotational misalignment, an estimated spatial misalignment, or both, between the first antenna array at the first wireless device and a second antenna array at the second wireless device. The first wireless device may then transmit a message to the second wireless device in accordance with a second precoder matrix that is modified relative to the first precoder matrix based at least in part on the estimated rotational misalignment, the estimated spatial misalignment, or both.
