Abstract: A first UE may schedule a first sidelink transmission and a second sidelink transmission. A first DMRS associated with the first sidelink transmission and a second DMRS associated with the second sidelink transmission may be bundled for channel estimation associated with a second UE. The first UE may schedule a first uplink transmission. The first uplink transmission may be TDMed or FDMed with at least one of the first sidelink transmission or the second sidelink transmission. The first UE may transmit at least one of the first sidelink transmission, the second sidelink transmission, or the first uplink transmission. The bundling of the first DMRS and the second DMRS may be maintained or canceled.

Abstract: This disclosure provides systems, methods and apparatus, including computer storage media, for sidelink communications using partial symbols to reduce overhead of automatic gain control (AGC) and gaps. A transmitting user equipment (UE) maps a sidelink signal to a subset of resource elements in a frequency domain allocation defined via a comb for a first orthogonal frequency division multiplexing (OFDM) symbol. The transmitting UE performs an inverse discrete Fourier transform (IDFT) on the resource elements to generate a first time domain signal that includes a number of repetitions of a first waveform based on a structure of the comb. The transmitting UE transmits at least one repetition of the first waveform of the first time domain signal during at least a portion of the first OFDM symbol. A receiving UE performs AGC and a discrete Fourier transform on portions of the time domain signal.

Abstract: Methods, apparatuses, and computer-readable medium for charging IoT devices are provided. An example method may include transmitting, to a user equipment (UE), a charging request to charge the IoT device. The example method may further include receiving, from the UE, a fulfillment or a denial associated with the charging request. The example method may further include broadcasting information related to the charging request after receiving the fulfillment or the denial associated with the charging request.

Abstract: Certain aspects of the present disclosure provide techniques for securing physical (PHY) layers in wireless communication. Certain aspects are directed to a method for wireless communication by a user equipment (UE). In some examples, the method includes obtaining a key and using the key during physical layer signal processing of a physical uplink control channel (PUCCH) transmission having more than one symbol to provide security for the PUCCH transmission.

Abstract: Disclosed are techniques for wireless communication. In an aspect, BS determines a channel state information (CSI) report field priority-based security scheme, and transmits CSI report field priority-based security scheme to UE. UE determines bit availability in CI (e.g., UCI or SCI or MAC CE) for transmission of a CSI report. UE configures, based on the CSI report field priority-based security scheme and the CI bit availability, the CSI report with first field(s) (e.g., secured with key) being secured via a key and second field(s) being unsecured (e.g., not secured with any key or secured with weaker key below strength threshold). UE transmits the CSI report to BS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver user equipment (UE) may receive, from a transmitter UE, a sidelink communication. The receiver UE may transmit, to the transmitter UE, based at least in part on receiving the sidelink communication, channel state information (CSI) using one or more resources of a physical sidelink shared channel (PSSCH). Numerous other aspects are described.

Abstract: Techniques for indicating system information block or paging waveforms for future communications may include a user equipment (UE) configured to identify a waveform configuration of a downlink (DL) signal including system information to be received from a base station during a random access channel (RACH) procedure in response to an indication of the waveform configuration of the DL signal. The UE may also be configured to receive, from the base station, the system information in response to the waveform configuration of the DL signal being identified.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) scheduling a downlink transmission. The UE may perform energy harvesting using the downlink transmission. The UE may transmit a hybrid automatic repeat request (HARQ) negative-acknowledgment (HARQ-NACK) based at least in part on using the downlink transmission for the energy harvesting. Numerous other aspects are described.

Abstract: Aspects are provided which allow a first device to secure transmission of polar encoded control information by encoding at least a portion of frozen bits and/or information bits with a shared key with a second device before these bits are encoded by a polar encoder. The first device determines whether to encode at least one of a plurality of frozen bits or a plurality of information bits using the shared key. Based on the determination, the first device encodes the frozen bits and/or the information bits, and sends the encoded frozen bits and/or the encoded information bits to the second device. Since the receiving device has the shared key, the receiving device may successfully decode the control information, while an eavesdropper who receives the encoded bits may fail to decode the control information due to lack of knowledge of the shared key.
