  • Publication number: 20240023119
    Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). Next generation of wireless cellular operation is expected to be deployed in higher frequency above 6 GHz (e.g., 10 GHz˜100 GHz, also called mmWave and/or cmWave) due to availability of large amount of spectrum bandwidths. The physical layer of wireless cellular system in both DL and UL operating in mmWave/cmWave would be based on new air-interface different from that of LTE-A air-interface because the radio characteristics is different for mmWave/cmWave bands. The wireless system deployed in mmWave/cmWave system is expected to employ DL beam sweeping on broadcast control information to provide cell coverage to the UE which would result in excessive signaling overhead.

  • Patent number: 11641263
    Abstract: Methods and apparatus are provided in which data is received from a base station on a downlink data channel. It is determined whether a scheduling type of the downlink data channel is persistent or non-persistent. In case that the scheduling type is non-persistent, ACK/NACK information for the data is transmitted to the base station on a resource which is determined based on a first ACK/NACK resource allocation scheme. In case that the scheduling type is persistent and the data is initial persistent data, ACK/NACK information for the data is transmitted to the base station on a resource which is determined based on the first ACK/NACK resource allocation scheme. In case that the scheduling type is persistent and the data is persistent data following the initial persistent data, ACK/NACK information for the data is transmitted to the base station on a resource determined based on a second ACK/NACK resource allocation scheme.
