  • Publication number: 20200275423
    Abstract: Methods and apparatus are described for a User Equipment (UE) with reduced processing capabilities (e.g., Machine Type Communication (MTC) UE) to transmit and receive signaling are provided. The Downlink Control Information (DCI) formats scheduling a transmission of a Physical Uplink Shared CHannel (PUSCH) or a reception of a Physical Downlink Shared CHannel (PDSCH) are designed and have a smaller size than respective DCI formats for conventional UEs. DCI formats scheduling PUSCHs to or PDSCHs for a group of MTC UEs are also designed and can have a same size as DCI formats scheduling PUSCH or PDSCH for an individual MTC UE.

  • Patent number: 10735073
    Abstract: A Channel Status Information (CSI) transmission method and apparatus of a terminal are provided for use in a wireless communication system. In the wireless communication system supporting carrier aggregation, the terminal transmits the CSIs of component carriers without conflict of their transmission time points, resulting in an improvement of system performance. In a case where the transmission time points are determined to overlap unavoidably, the terminal transmits the CSI as compressed.
