Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may receive one or more service data units (SDUs) at a layer two (L2) layer of the transmitting device. The transmitting device may encode, at the L2 layer, the one or more SDUs according to one or more network coding parameters to obtain at least one encoded protocol data unit (PDU), the one or more network coding parameters comprising a rateless code. The transmitting device may generate, for the at least one encoded PDU, at least one corresponding PDU header. The transmitting device may output the at least one encoded PDU and the at least one corresponding PDU header from the L2 layer to a lower layer of the transmitting device for transmission to one or more receiving devices.

Abstract: Methods, systems, and devices for wireless communications are described. An encoding device may encode a set of source symbols using one or more raptor codes to generate a first set of encoded symbols and may transmit the first set of encoded symbols to a decoding device. The decoding device may successfully recover a source symbol of the set of source symbols from the first set of encoded symbols and may transmit an indication of the source symbol to the encoding device. The encoding device may encode one or more source symbols of the set of source symbols using the one or more raptor codes to generate a second set of encoded symbols based on receiving the indication of the source symbol and may transmit the second set of encoded symbols to the decoding device.

Abstract: Apparatus, methods, and computer-readable media for facilitating CSI feedback in multiple-TRP communication are disclosed herein. An example method of wireless communication by a UE includes receiving, from a base station, a report configuration message triggering a channel state feedback procedure, the UE and the base station operating in a multiple transmission and reception point (multiple-TRP) communication mode, the report configuration message requesting a multiple-TRP transmission value including at least one of a quantity of layer indicator (LI) values and a strongest TRP indicator (STI) value. The example method also includes generating channel state information (CSI) information based on the receiving of the report configuration message, the CSI information including the multiple-TRP transmission value. The example method also includes transmitting, to the base station, a report including the generated CSI information.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a device to distinguish between signals transmitted using frequency modulated continuous wave (FMCW) waveforms. A first wireless device may apply a frequency-domain (FD) scrambling sequence to a reference signal for transmission, and a second wireless device may receive at least a portion of the signal and de-scramble the signal using the FD scrambling sequence. In some examples, the first wireless device may transmit configuration signaling indicating the FD scrambling sequence corresponding to the first wireless device. Additionally, or alternatively, the first wireless device may transmit an indication for the second wireless device to determine the FD scrambling sequence based on identifier (ID) information (e.g., an ID associated with the first wireless device). In some examples, the first wireless device, the second wireless device, or both may use analog or digital transceivers.

Abstract: An aerial device receives a timing advance configuration from a base station for sidelink communication with one or more user equipments (UEs), the timing advance configuration indicating an initial timing advance for the sidelink communication with the one or more UEs. The aerial device transmits a discovery message from the aerial device to the one or more UEs at a transmission time based on the initial timing advance relative to a reference time of a sidelink synchronization reference.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a downlink visible light communication (VLC) transmission. The UE may receive, from the base station, a downlink New Radio (NR) radio frequency (RF)-based communication (RFC) transmission, wherein a frame structure associated with the downlink VLC transmission is asynchronous with a frame structure associated with the downlink NR RFC transmission. The UE may transmit, to the base station via an uplink RF transmission based at least in part on a lack of support for an uplink VLC transmission at the UE, acknowledgement or negative acknowledgement (ACK/NACK) feedback associated with one or more of the downlink VLC transmission or the downlink NR RFC transmission. Numerous other aspects are described.
