Method and apparatus for transmitting data in wireless communication system

A method for transmitting data to a base station (BS) by a user equipment (UE), the method comprising:

• receiving information on a contention-based Physical Uplink Shared Channel (PUSCH) zone including a plurality of contention-based PUSCH resource blocks from the base station (BS);
• allocating at least one contention-based PUSCH resource block for transmission of the data based on the information on contention-based PUSCH zone;
• and
• transmitting the data to the base station (BS),
• wherein the at least one contention-based PUSCH resource block is determined based on a UE identifier (ID).

A method for transmitting data to a base station (BS) by a user equipment (UE), the UE comprising:

• receiving information on a contention-based Physical Uplink Shared Channel (PUSCH) zone including a plurality of contention-based PUSCH resource blocks from the base station (BS);
• allocating at least one contention-based PUSCH resource block for transmission of the data based on the information on contention-based PUSCH zone;
• and
• transmitting the data to the base station (BS),
• wherein the at least one contention-based PUSCH resource block is arbitrarily determined.

A method for transmitting data by a base station (BS), the BS comprising:

• transmitting information on a contention-based Physical Uplink Shared Channel (PUSCH) zone including a plurality of contention-based PUSCH resource blocks to a first user equipment (UE);
• and
• receiving the data from the first UE,
• wherein the data is allocated to at least one contention-based PUSCH resource block based on the information on contention-based PUSCH zone, and is then transmitted,
• wherein the at least one contention-based PUSCH resource block is determined based on a preamble sequence.
