Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a UE. The apparatus attempts to receive a downlink transmission from a base station and determines to transmit a NACK to the base station for the downlink transmission. The UE transmits the NACK to the base station in a common resource in an uplink control channel, wherein the common resource is common to multiple UEs communicating with the base station. The UE may also transmit the NACK using a resource granted to the UE in the uplink control channel. Thus, the transmission of the NACK in the common resource may comprise a repetition of the NACK transmitted using the resource granted to the UE. The common resource may comprise a Non-Orthogonal Multiple Access (NOMA) resource. Thus, the UE may apply a NOMA sequence to the NACK prior to transmission of the NACK in the common resource.

Abstract: Various aspects described herein relate to techniques for managing downlink control information (DCI) in wireless communications (e.g., 5G NR). In an aspect, the method includes receiving a radio resource control (RRC) message, identifying a transport block size (TBS) based on the received RRC message, receiving DCI on a downlink channel with the DCI including a resource assignment, identifying a modulation order using a modulation and coding scheme (MCS) in an MCS field of the DCI, where the size of the MCS field is one bit or two bits, and calculating a coding rate based on at least the identified TBS, the identified modulation order and the resource assignment.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications at an ambient internet of things (IoT) device. The ambient IoT device measures signal strength of a downlink signal transmitted from a gNodeB (gNB). The ambient IoT device estimates a pathloss between the gNB and itself based at least on the measured signal strength. Based on the pathloss between the ambient IoT device and the gNB, and together with measured received power from an assisting node, the ambient IoT device may select a random access channel (RACH) occasion (RO) so that a received power at the gNB from the ambient IoT device is constrained to a limited range.

Abstract: Disclosed are systems and techniques for wireless communications. For example, a first network device can transmit, to second network device(s), a first information signal including information indicating a frequency for a backscattered signal. The first network device can transmit, to a third network device, a second information signal including information indicating a frequency shift for shifting a reference signal to produce the backscattered signal. The first network device can transmit the reference signal to the third network device. The first network device can select, based on channel reports received from the second network device(s), the energy harvesting waveform and at least one second network device for providing the energy harvesting waveform to the third network device. The first network device can transmit, to the at least one second network device, a scheduling signal including scheduling instructions to transmit the energy harvesting waveform to the third network device.

Abstract: Methods, systems, and devices for wireless communications are described. An energy receiver may receive a first message that includes information indicative of a time division duplex (TDD) configuration for wireless energy and information transfer, the TDD configuration indicating a temporal arrangement of energy and information resources. In some examples, an energy transmitter may configure the TDD configuration as cell-specific, energy receiver-specific, or using a slot format indication (SFI). In addition, the TDD configuration may include flexible resources able to be used for energy or information transfer. The energy receiver may receive one or more energy signals during the energy resources in accordance with the TDD configuration, the one or more energy signals providing energy to the energy receiver. Accordingly, the energy receiver may transmit one or more information signals during the information resources in accordance with the TDD configuration.

Abstract: The apparatus may be a network node configured to transmit, to a backscatter-capable device, a first indication of a first frequency range associated with a downlink (DL) transmission, a second indication of a second frequency range associated with an uplink (UL) communication from the backscatter-capable device, and a third indication of a third frequency range associated with an UL trigger from the backscatter-capable device. The apparatus may further be configured to receive, via the third frequency range, the UL trigger indicating that the backscatter-capable device has information to transmit. The apparatus may also be configured to transmit, based on receiving the UL trigger and via the first frequency range, a CW DL transmission for backscattering from the backscatter-capable device and receive, via the second frequency range, the information from the backscatter-capable device via the CW DL transmission backscattered by the backscatter-capable device.
