Abstract: The aspects described herein allow control of an energy harvesting operation at an apparatus in a discontinuous reception (DRX) mode. The apparatus in the DRX mode may reduce its power consumption and may immediately begin harvesting energy during an active time of a DRX cycle. The apparatus includes a memory and at least one processor coupled to the memory. The at least one processor is configured to enter a DRX mode and receive a control signal during an active time of the DRX mode. The control signal enables an energy harvesting operation at the apparatus. The at least one processor is further configured to perform the energy harvesting operation in response to the control signal, wherein the energy harvesting operation is performed based on at least one of a reported capability, a preconfigured energy harvesting setting, control information in the control signal, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a device such as a user equipment (UE), a base station, or both, to perform a channel noise and interference estimation based on a set of null resources in a data channel. The device may identify a first configuration for a set of demodulation reference signals (DMRSs) in a first set of time periods of a data channel and a second configuration for a set of null resources in a second set of time periods of the data channel. The second set of time periods may be nonoverlapping with the first set of time periods. The device may perform a channel estimation procedure on the data channel based on the null resources and the DMRS resources. The device may process data received via resources of the data channel based on the channel estimation procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a transport block that includes a number of code block groups (CBGs). The UE may transmit a feedback communication associated with the transport block, wherein the feedback communication indicates feedback associated with the CBGs using a number of feedback bits, and wherein the number of feedback bits is less than the number of CBGs of the transport block. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide mechanisms for reducing the payload size of the channel state information (CSI) multiplexed together with deferred acknowledgement information. In some examples, a user equipment (UE) may transmit combined acknowledgement information including the respective acknowledgement information for one or more of received packets, along with turbo acknowledgement information including both the respective acknowledgement information and the respective CSI feedback for one or more remaining ones of the packets within an uplink resource.

Abstract: A user equipment may be configured to implement a procedure for aligning transmissions for intra-band carrier aggregation in sidelink communications. In some aspects, a user equipment may send one or more first transmissions to a second UE via a first sidelink component carrier, a first transmission of the one or more first transmissions including first user data. Further, the user equipment may send one or more second transmissions to a third UE via a second sidelink component carrier, the one or more first transmissions aligned with the one or more second transmissions and a second transmission of the one or more second transmissions including second user data and a repetition of a portion of the second user data.

Abstract: To provide hybrid automatic repeat request (HARQ) feedback transmission with channel state information (CSI) report, a UE may receive triggering information associated with transmitting one or more channel state information (CSI) reports associated with one or more downlink (DL) semi-persistent scheduling (SPS) transmissions in one or more physical downlink shared channel (PDSCH) occasions. The UE may receive a first DL SPS transmission of the one or more DL SPS transmissions in a first PDSCH occasion of the one or more PDSCH occasions. The UE may transmit a first CSI report associated with the first DL SPS transmission based on receiving the triggering information.
