  • MULTIPLE SIDELINK FEEDBACK CHANNEL OCCASION PROCEDURES
    Publication number: 20230421309
    Abstract: Methods, systems, and devices for wireless communications are described. One or more user equipments (UEs) may communicate in a wireless communications system by transmitting and receiving sidelink messages from other UEs. The UEs may transmit acknowledgement (ACK) or negative acknowledgment (NACK) feedback based on reception of sidelink messages for other UEs. The UEs may identify a sidelink feedback resource set including a set of feedback transmission slots for transmitting sidelink feedback. The UEs may perform NACK-only feedback, and may streamline feedback transmissions based on monitoring for other NACKs from other UEs. The UEs may prioritize feedback transmissions when the UE has multiple feedback transmissions queued, and when a UE has feedback to transmit and to receive in overlapping transmission time intervals (TTIs).

  • SLOT DURATION ADAPTATION IN UNLICENSED FREQUENCY SPECTRUM
    Publication number: 20230397251
    Abstract: Aspects for reducing interference for transmissions in unlicensed frequency bands are disclosed. An apparatus, e.g., a user equipment (UE) with information to transmit, identifies before transmitting the information in an unlicensed frequency spectrum, a specified duration of a listen-before-talk (LBT) operation in that spectrum. Based on the specified duration, the UE reduces a transmission time duration of a slot of the UE to increase a time duration of a remainder of the slot sufficient to prevent, or decrease the likelihood of, a transmission by the UE in the slot from interfering with an LBT operation by another UE.

    Patent number: 11831442
    Abstract: Transmit and receive wireless communication devices configured to independently determine the same transport block size (TBS) for use with sidelink communications. In an illustrative example, a transmitting device includes a transceiver; a memory; and a processor, with the processor configured to generate or obtain a Physical Sidelink Feedback Channel (PSFCH) overhead indicator indicating whether PSFCH overhead is used in determining the TBS. The processor also determines a number of demodulation reference signal (DMRS) resource elements (REs) associated with DMRS overhead for use in the TBS determination. The processor determines the TBS based on the number of DMRS REs and on the PSFCH overhead indicator, and then transmits signals to a receiving device using sidelink wireless communication that include a PSFCH overhead indicator. The signals are transmitted according to the determined TBS.
