Abstract
A modem chip for supporting combination of data repeatedly transmitted based on hybrid automatic repeat request (HARQ) is provided. The modem chip includes an HARQ combiner configured to perform a HARQ combination by combining retransmitted data with the previous HARQ data, the retransmitted data including retransmitted control channel data received via a control channel and retransmitted data channel data received via a data channel, the previous HARQ data corresponding to data received via the control channel and the data channel, the HARQ combination generating updated HARQ data, a memory configured to store the previous HARQ data and the updated HARQ data, and a memory controller configured to control transmission of the previous HARQ data and the updated HARQ data between the HARQ combiner and the HARQ memory.
