METHOD FOR TRANSMITTING AND RECEIVING UPLINK/DOWNLINK DATA WITH MTC DEVICE

摘要

According to an embodiment of the present specification, a method for transmitting uplink data in a machine type communication (MTC) device is provided. The method may comprise the steps of: initially transmitting repetitive bundles of physical uplink shared channel (PUSCH) data including identical uplink data in a plurality of uplink subframes to a base station; receiving a hybrid automatic repeat request (HARQ) response signal with respect to the repetitive bundles of PUSCH; if the HARQ response signal is a negative-acknowledgement (NACK), determining the number of repetitions of the PUSCH including identical uplink data; and re-transmitting the PUSCH bundles repeatedly for the determined number of times on the plurality of uplink subframes to the base station.

1. A method for transmitting uplink data device, the method performed by a machine type communication (MTC) and comprising:
transmitting initially a bundle of repeated physical uplink shared channels (PUSCHs) including same uplink data to a base station on a plurality of uplink subframes; receiving a hybrid automatic repeat request (HARQ) response signal from the base station in response to the bundle of repeated PUSCHs; determining a repetition number of PUSCH including the same uplink data, if the HARQ response signal is negative-acknowledgement (NACK); and retransmitting the bundle of PUSCHs, which are repeated by the determined repetition number on a plurality of uplink subframes, to the base station.
