  • Publication number: 20230262689
    Abstract: Aspects of the present disclosure provide techniques for handling scenarios where a physical uplink shared channel (PUSCH) repetition is scheduled as a single symbol. According to certain aspects, a user equipment (UE) is configured to detect that a nominal physical uplink shared channel (PUSCH) repetition is to be segmented into one or more actual PUSCH repetitions that include a single symbol actual PUSCH repetition and take one or more actions to handle a symbol length gap in transmission due to the single symbol actual PUSCH repetition.

  • Publication number: 20230261694
    Abstract: Wireless communications systems and methods related to frequency hopping in uplink transmission. A UE may be configured to transmit a first subset of data on a first frequency band to a BS over a first set of symbols. The UE may perform a listen-before-talk (LBT) during an LBT gap comprising a second set of symbols between the first set of symbols and a third set of symbols. The UE may use the LBT in the LBT gap to determine availability of a second frequency sub-band for a second subset of data that is a repetition of the first subset of data. The UE may be configured to transmit the second subset of data on the second frequency band to the BS over a third set of symbols if the LBT passes. Thus, embodiments of the present disclosure enable a UE to perform frequency hopping with repetitions across unlicensed frequency sub-bands.
