  • Patent number: 11963186
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) and indicating a physical uplink control channel (PUCCH) repetition factor. The UE may transmit, and the base station may receive, a PUCCH that includes hybrid automatic repeat request acknowledgement feedback associated with the PDSCH. In some aspects, one or more instances of the PUCCH are transmitted across one or more uplink slots or sub-slots based at least in part on the PUCCH repetition factor indicated in the DCI. Numerous other aspects are provided.

  • Patent number: 11956082
    Abstract: Aspects presented herein may enhance a HARQ feedback operation to improve data retransmissions by using tri-state HARQ feedback, and may enable a UE to construct a codebook for tri-state HARQ feedback. In one aspect, a UE determines whether tri-state HARQ feedback or bi-state HARQ feedback is configured based on a DL carrier. The UE generates HARQ feedback for at least one of a received PDCCH or a received PDSCH on the DL carrier based on the determination whether the DL carrier is configured with the tri-state HARQ feedback. The UE transmits the generated HARQ feedback.

  • Patent number: 11949618
    Abstract: Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.

  • Publication number: 20240089766
    Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.

  • Publication number: 20240073916
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus for wireless communication at a wireless node comprises one or more memories, and one or more processors, coupled to the memory. The one or more processors can be configured to transmit or receive tri-state feedback indicating a result of decoding one or more communications. The tri-state feedback can be associated with three potential states. The three potential states can indicate whether (i) decoding of a control channel was unsuccessful, (ii) decoding of the control channel was successful and decoding of a data channel was unsuccessful, or (iii) decoding of the control channel and the data channel was successful.
