  • WAKING-UP A WIRELESSLY-POWERED DEVICE
    Publication number: 20240163800
    Abstract: Methods, systems, and devices for wireless communications are described. For instance, a wireless device (e.g., abase station, a user equipment (UE)) may transmit a wake-up message including an indicator of whether an on duration of a discontinuous reception cycle is associated with harvesting energy from a signal transmitted during the on duration. The wireless device may transmit the signal during the on duration based on the wake-up message. In some examples, the UE may determine, from the indicator, whether to harvest energy, decode data or both during the on duration. If both harvesting energy and decoding data, the UE may harvest the energy and decode the data concurrently for at least a portion of the on duration. Additionally, or alternatively, the UE may harvest the energy during a first portion of the on duration and may decode data during a second portion of the on duration.

  • TECHNIQUES FOR INTRA-USER EQUIPMENT AND INTER-USER EQUIPMENT CANCELATION OF OVERLAPPING COMMUNICATIONS
    Publication number: 20240155629
    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.
