Abstract
A method and an apparatus are provided for transmitting and receiving uplink data in a wireless communication system. A method includes transmitting information on hopping; determining whether mirroring is applied or not based on a packet transmission number, if the information on hopping indicates that a predefined hopping pattern is enabled; identifying a resource for receiving the uplink data based on the determination as to whether the mirroring is applied or not; and receiving the uplink data using the identified resource.
Claims16
A method for receiving uplink data by a base station in a wireless communication system, the method comprising:
- transmitting first information on hopping;
- determining, as a result of the first information on hopping indicating that a hopping pattern for a terminal is a predefined pattern, whether a mirroring is applied to a resource for receiving the uplink data or not based on a modulo operation using a number of uplink transmissions associated with a hybrid automatic repeat request (HARQ) process for the uplink data, such that an initial transmission and retransmission of the uplink data are transmitted on different frequency resources;
- identifying the resource based on the determination as to whether the mirroring is applied or not;
- and
- receiving the uplink data using the identified resource.
