Abstract: Methods, apparatus, and systems that enable scheduling of related data transmissions across multiple cells and/or carriers are disclosed. In one example aspect, a method for wireless communication includes processing, by a base station, a first data transmission for a user device on a first serving cell and transmitting, by the base station to the user device, a control message that includes a scheduling information of a second data transmission on a second cell that is different than the first serving cell. The control message indicates whether the second data transmission is a new data transmission or a retransmission of the first data transmission. The method also includes processing, by the base station, the second data transmission for the user device on the second cell according to the scheduling information.

Abstract: The present disclosure provides a method and an apparatus for receiving Channel Quality Indication (CQI) information, as well as a method and an apparatus for transmitting CQI information. The method for receiving CQI information includes: transmitting a higher layer configuration signaling message to a terminal; and receiving CQI information from the terminal. The CQI information is determined based on a CQI table obtained based on the higher layer configuration signaling message. With the above solutions, higher data transmission reliability and lower data transmission rate required for MTC terminals with coverage enhancement and 5G terminals can be achieved.
