    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network entity may encode first information using keying modulation. The first network entity may encode second information using frequency modulated continuous waveform (FMCW) modulation. The first network entity may transmit a communication that includes a first layer indicating the first information and a second layer indicating the second information. Numerous other aspects are described.

    Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive a first stage wakeup signal (WUS) indicating to monitor for a second stage WUS using a low power radio. For example, the first stage WUS may indicate whether to monitor one or more upcoming monitoring occasions for the second stage WUS using the low power radio. The UE may receive the second stage WUS based on receiving the indication included in the first stage WUS. The second stage WUS may indicate for the UE to activate a main radio to monitor for a control channel to receive data transmitted by the network entity. Based on receiving the second stage WUS, the UE may activate the main radio and receive data from the network entity.

    Abstract: A first device may transmit an indication of a base graph recommendation. A second device may receive the indication of the base graph recommendation. The second device may select a base graph from a plurality of base graphs based on the base graph recommendation. The second device may transmit an indication of the selected base graph from the plurality of base graphs after the selection of the indication of the base graph recommendation. The first device may receive the indication of the selected base graph from the plurality of base graphs after an output of the indication of the base graph recommendation. The second device may transmit a low density parity check (LDPC) coded transmission based on the selected base graph. The first device may receive the LDPC coded transmission based on the selected base graph.

    IPC: H04L1/00

    Abstract: An apparatus (e.g., a transmitter) may transmit a message and one or more retransmissions of the message in a wireless communication network. The message may include a codeword that includes information bits and error correction bits (e.g., parity bits). The one or more retransmissions may include error correction bits associated with the information bits. To improve the decoding performance at a receiver, the transmitter may apply probabilistic shaping to the one or more retransmissions. In some aspects, the apparatus transmits a first message including information bits and a first set of error correction bits associated with the information bits. The apparatus transmits at least a second message associated with the first message, wherein the second message includes a second set of error correction bits associated with the information bits and a set of probabilistic shaping bits for the second set of error correction bits.

    Abstract: Methods, systems, and devices for wireless communications are described. Energy harvesting (EH)-capable devices may harvest energy from different sources, such as a radio frequency sources or environmental conditions such as solar energy. The consumed energy by the EH-capable device may be dependent on a task type and the properties of the EH-capable device. Processing of data symbols, demodulation reference signal symbols, and control symbols may involve different energy costs at the EH-capable device. An EH-capable device configured with multiple slot formats may report to the network the immediate energy status and capabilities of the EH-capable device and/or respective energy costs for the EH-capable device for each of the slot formats. The network may schedule communications involving the EH-capable device (e.g., sidelink communications, uplink communications, or downlink communications) based on the energy costs for the EH-capable device for the multiple slot formats and/or the energy status of the EH-capable device.

    Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may employ one or more scheduling constraints to support efficient utilization of techniques for intra-device handling of overlapping scheduled uplink transmissions (e.g., intra-device dynamic resource cancelation and multiplexing) as well as inter-device handling of overlapping scheduled uplink transmissions (e.g., inter-device dynamic resource cancelation and multiplexing). Scheduling constraints may define how a device may apply intra-device and inter-device multiplexing and cancelation rules for various scenarios. For example, a device may apply intra-UE cancelation rules before inter-device cancelation rules. In some examples, later-received grants or uplink preemption indications (ULPIs) may not change a device's previously established decision to drop an uplink transmission. As another example, a device may not expect to receive a grant for an uplink transmission that would arise in subsequent cancelation of that uplink transmission due to a previously-received grant or previously-received ULPI.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first signal in a frequency domain, the first signal being a dual band signal that is a function of a second signal transmitted in the frequency domain, the second signal being transmitted on a same symbol or a same set of symbols as the first signal in the frequency domain, and the first signal having a lower transmission power than the second signal. The UE may perform an action based at least in part on the first signal. Numerous other aspects are described.

    Abstract: Methods, systems, and devices for wireless communications are described. For example, a network entity may transmit, and a user equipment (UE) may receive, for generation of a demodulation reference signal sequence corresponding to a resource block allocation, control signaling indicative of a selection of a root number and a prime number. The prime number is one of two or more prime numbers used to generate a set of demodulation reference signal sequences for the resource block allocation. The UE may generate, using the prime number and the root number as input into a sequence generation function, the demodulation reference signal sequence of the set of demodulation reference signal sequences corresponding to the resource block allocation and transmit a physical uplink shared channel transmission including the demodulation reference signal sequence.
