  • Publication number: 20180343645
    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: 10123319
    Abstract: Methods and apparatus are provided for the transmission of physical downlink control signaling. In one method, a User Equipment (UE) receives information associated with a physical resource block (PRB) for enhanced physical downlink control channel (EPDCCH) from a base station. Based on either first information received on physical control format indicator channel (PCFICH) or second information received on higher layer signaling, the UE determines a starting orthogonal frequency division multiple (OFDM) symbol on which EPDCCH transmission starts. The UE receives control information on the EPDDCH based on the information associated with the PRB and the determined starting OFDM symbol.
