  • Publication number: 20250141644
    Abstract: Various aspects of the present disclosure relate to a UE that receives an indication of one or more system information transmission repetition periodicity values corresponding to a respective subset of synchronization signal blocks (SSBs) within a burst of SSBs. The UE selects at least one SSB from the burst of SSBs, and receives a system information message via one or more physical downlink control channel (PDCCH) monitoring occasions in a search space set for the system information message. The one or more PDCCH monitoring occasions, for instance, are determined based on a system information transmission repetition periodicity value of the one or more system information transmission repetition periodicity values, and the system information transmission repetition periodicity value corresponds to the selected SSB. The UE can implement wireless communication using system information determined from the received system information message.

  • Patent number: 12289760
    Abstract: A method and apparatus are provided, in which information of a feedback time for transmitting a feedback message from the user equipment for a physical shared channel message is received (402). A maximum allowed feedback time delay associated with the feedback message for the physical shared channel message is determined (404). A physical channel occasion available to be used by the user equipment for transmitting the feedback message is identified (406). The feedback message is transmitted when the identified available physical channel occasion, which is available to be used for the feedback message, allows for the feedback message to be transmitted within the maximum allowed feedback time delay, otherwise the feedback message is not transmitted, when the identified available physical channel occasion does not allow for the feedback message to be transmitted within the maximum allowed feedback time delay (408).
