Abstract
The present invention relates to a wireless communication system. In detail, the present invention is a method for transmitting data to a base station (BS) by a user equipment (UE) includes: 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).
Claims16
A method for performing a random access procedure by a user equipment (UE) in a wireless communication system, the method comprising:
- transmitting a random access preamble on a physical random access channel (PRACH) and uplink (UL) data on a contention-based physical uplink shared channel (PUSCH);
- receiving a random access response (RAR) message in response to the random access preamble, wherein the RAR message includes an UL grant for transmitting the UL data;
- and
- retransmitting the UL data on the UL grant.
A user equipment (UE) for performing a random access procedure in a wireless communication system, the UE comprising:
- a radio frequency (RF) module;
- and
- a processor configured to control the RF module,
- wherein the processor is configured to control the RF module to:
- transmit a random access preamble on a physical random access channel (PRACH) and uplink (UL) data on a contention-based physical uplink shared channel (PUSCH);
- receive a random access response (RAR) message in response to the random access preamble, wherein the RAR message includes an UL grant for transmitting the UL data;
- and
- retransmit the UL data on the UL grant.
