Abstract: Provided are a method for determining the number of hybrid automatic repeat request (HARQ) processes in a carrier aggregated system configured with a plurality of serving cells, and an apparatus using such a method. The method receives data from a downlink subframe of a second serving cell, and transmits an ACK/NACK signal for the data from an uplink subframe of a first serving cell, wherein the first serving cell uses a first-type frame, the second serving cell uses a second-type frame, and the number of HARQ processes in the second serving cell are determined with respect to each subframe comprised in the second-type frame and on the basis of the number of downlink subframes comprised in each section comprising a set number of subframes.

Abstract: A method and apparatus for allocating resources for a machine type communication user equipment (MTC UE) in a wireless communication system is provided. A base station indicates a transport block size (TBS) directly, adapts a code rate according to repetition numbers across multiple subframes in a MTC physical downlink shared channel (M-PDSCH) for the MTC UE, and allocates resources for the M-PDSCH by using the indicated transport block size and the adapted code rate. The TBS may be determined based on a modulation and coding scheme (MCS) only.

Abstract: A method and apparatus for determining a control resource set for system information in a wireless communication system is provided. A user equipment (UE) receives a configuration of control resource set (CORESET) for remaining system information (RMSI) via a synchronization signal (SS) block from a network, and determines the control resource set for the RMSI according to the configuration. The SS block may include a physical broadcast channel (PBCH). A time and frequency location of a common search space (CSS) for the RMSI may be aligned with the SS block by at least one of time division multiplexing (TDM) or frequency division multiplexing (FDM).
