  • Publication number: 20210410117
    Abstract: A scheme for control resource set (CORESET) control channel element (CCE) to resource element group (REG) mapping. The terminal device determines a set of physical downlink control channel (PDCCH) candidates based on one or more CORESET CCE to REG mapping related parameters. The one or more CORESET CCE to REG mapping related parameters are fixed. In one scheme, the terminal device obtains information by detecting a synchronization signal (SS)/physical broadcast channel (PBCH) block. The terminal device determines one or more CORESET CCE to REG mapping related parameters, based on the information obtained during the detection of the SS/PBCH block. A correspondence between the one or more CORESET CCE to REG mapping related parameters and the obtained information is predefined between the terminal device and a BS. The terminal device determines a set of PDCCH candidates based on the one or more CORESET CCE to REG mapping related parameters.

    Abstract: The present disclosure described systems and methods for providing OTT services to a UE. An exemplary OTT-providing host computer includes a transceiver, a processor, and memory collective configured to provide the OTT service by initiating transmission of user data to the UE. To transmit the user data from the host computer to the wireless device, a network node sends a first control message for assigning a PDSCH, the first control message comprising a first MCS indication as described. The network node sends to the wireless device a second control message for assigning a PDSCH, the second control message comprising a second MCS indication as described. The network node transmits the user data thereafter.
