Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may transmit, to a base station, a report indicating a capability of the UE to support symbol level quantization, slot level quantization, or both. The UE may identify that the UE is to utilize the slot level quantization For instance, the UE may receive control signaling indicating that the UE is to utilize slot level quantization and may perform the identifying based on receiving the control signaling The UE may receive a first transmission via a first channel and may communicate, responsive to receiving the first transmission, a second transmission via a second channel at a quantized start timing determined in accordance with the slot level quantization.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

Abstract: This disclosure provides methods, devices and systems for harvesting radio frequency (RF) energy based on an energy harvesting EH indication signal. A transmitting device such as a base station may transmit, to a user equipment (UE), an EH indication signal that indicates a time period when radio frequency (RF) energy is to be available. The UE may receive the EH indication signal and harvest RF energy from the RF signal during the time period. The transmitting device may transmit an RF signal to the UE or another UE during the time period. The UE may receive a wake up indication indicating a second time period to monitor a control channel. The UE may split power between energy harvesting and receiving RF signals during the second time period.

Abstract: Certain aspects of the present disclosure provide techniques for a low cost (LC) user equipment (UE) to signal to a base station (BS) capabilities to receive physical downlink control channels (PDCCHs) in wireless communications systems. In an exemplary method, a UE signals to a base station (BS) a plurality of parameters for physical downlink control channel (PDCCH) reception by the UE and receives a PDCCH according to the plurality of parameters.

Abstract: The apparatus, in some aspects may be a UE configured to communicate, in a FD mode, with at least one base station. The UE may further be configured to determine, when communicating with the at least one base station in the FD mode, FD UE assistance information including one or more FD UE assistance parameters. The UE may also be configured to transmit, to the at least one base station, an indication of the determined FD UE assistance information including the one or more FD UE assistance parameters. In some aspects, the apparatus may be a base station configured to communicate with at least one UE operating in a FD mode. The base station may further be configured to receive, from the at least one UE, an indication of FD UE assistance information including one or more FD UE assistance parameters.

Abstract: In an aspect, a satellite-based non-terrestrial network configures multiple preconfigured uplink resources (PURs) for a user equipment (UE). The PURs may be configured one PUR per beam, one PUR per cell, or one PUR for multiple cells. A serving cell of the UE and one or more cells adjacent to the serving cell may each have an associated PUR. The UE selects one of the multiple PURs and sends a transmission using the selected PUR without the UE have a connection to the network. The network sends an ACK in response to the transmission. Either the UE or the network can specify that the UE is to transmit using a first PUR and receive the ACK on a second PUR. The UE can specify when and which PUR to use in the transmission and the network can specify when and which PUR to use in the ACK.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a high Doppler configuration is activated. The UE may detect, based at least in part on receiving the indication that the high Doppler configuration is activated, a phase tracking reference signal (PTRS) for a remaining minimum system information (RMSI) communication. The PTRS may be configured by the high Doppler configuration. Numerous other aspects are provided.
