Abstract: Methods, systems, and devices for wireless communications are described. A wireless communication device may receive, via a first radio frequency spectrum band, a control message that includes an uplink grant for sending one or more backscattered uplink messages via a second radio frequency spectrum band that is higher than in frequency than the first radio frequency spectrum band and separated from the first radio frequency spectrum band by at least a threshold frequency gap. The wireless communication device may then receive a continuous waveform via the second radio frequency spectrum band, and modulate the continuous waveform with uplink data of the one or more backscattered uplink messages. The wireless device may then send, via the second radio frequency spectrum band, a backscattered signal of the continuous waveform based on modulating the continuous waveform with the uplink data.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a network device can transmit, to a group of passive devices, a continuous wave (CW) signal. The network device can receive, from each passive device of the group of passive devices, at least one backscatter signal, based on the CW signal, at a respective frequency shift. The network device can estimate, based on the at least one backscatter signal, channel information for each passive device of the group of passive devices. The network device can then determine, based on the channel information, a channel for transmitting an energy signal to at least one passive device of the group of passive devices for energy harvesting.

Abstract: Systems and techniques are provided for wireless communication. For example, a network device can transmit radio frequency (RF) signals. Each RF signal of the RF signals is associated with a respective sub-band of sub-bands included in a wideband bandwidth. The network device can receive, from an energy harvesting (EH)-capable device, backscatter RF signals. Each backscatter RF signal of the backscatter RF signals is associated with a respective RF signal of the RF signals. Each backscatter RF signal and each respective RF signal are associated with a respective sub-band of the sub-bands included in the wideband bandwidth. The network device can determine control information associated with the wideband bandwidth based on the backscatter RF signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a channel access procedure associated with a transmission of a sidelink communication that is to be associated with resources that are associated with a first configured grant configuration, wherein the channel access procedure is unsuccessful, wherein the sidelink communication is associated with a hybrid automatic repeat request (HARQ) process identifier, and wherein a state associated with the HARQ process identifier is changed to pending based on the channel access procedure being unsuccessful. The UE may transmit, based on successfully performing another channel access procedure, a retransmission of the sidelink communication using resources associated with the first configured grant configuration or a second configured grant configuration based on the state associated with the HARQ process identifier being changed to pending. Numerous other aspects are described.
