    Abstract: A method for a User Equipment (UE) for performing uplink transmissions for Random Access (RA) is provided. The method receives, from a base station, at least one configuration indicating a first threshold and initiates an RA procedure. The method determines whether to perform Multiple Physical Random Access Channel (PRACH) (MP) transmissions based on, at least, a comparison between a measurement result and the first threshold. The method then selects a PRACH resource configured for the MP transmissions in response to determining that the MP transmissions are to be performed. Performing the MP transmissions includes transmitting, repeatedly, an RA preamble, on the PRACH resource configured for the MP transmissions, before the UE begins monitoring a Physical Downlink Control Channel (PDCCH) for receiving a Random Access Response (RAR) that corresponds to the RA preamble.

  • Patent number: 12028888
    Abstract: A method for transmitting a HARQ-ACK by a UE is provided. The method receives an SPS configuration. The method then receives a DCI format which activates the SPS configuration and also indicates a first offset for transmitting the HARQ-ACK. After receiving an SPS PDSCH associated with the SPS configuration in a first slot, the method identifies a second slot based on the first slot and the first offset for transmitting the HARQ-ACK. The method determines whether a first PUCCH for transmitting the HARQ-ACK is contained within uplink/flexible symbols of the second slot. When the first PUCCH is not contained within the uplink/flexible symbols and also a parameter that is included in the SPS configuration indicates a deferred HARQ transmission, the method identifies a third slot based on the first slot and a second offset and transmits the HARQ-ACK on a second PUCCH in the third slot.
