Method and apparatus for transmitting data in wireless communication system
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).
1. A method for transmitting data to a base station (BS) by a user equipment (UE) in a wireless communication system, comprising:
receiving Physical Uplink Shared Channel (PUSCH) configuration including information on at least one contention-based PUSCH resource block from the BS;
allocating the at least one contention-based PUSCH resource block for transmission of the data based on the PUSCH configuration; and
transmitting the data to the BS,
wherein the at least one contention-based PUSCH resource block is determined based on a Physical Random Access Channel (PRACH) preamble.
2. The method according to claim 1 , wherein the at least one contention-based PUSCH resource block is determined by the following equation,
Contention-based PUSCH resource block=(Preamble Sequence)mod N [Equation]
where N is a modulo operation, and N is a number of contention-based PUSCH resource blocks configured by the PUSCH configuration, and the Preamble Sequence is a sequence of the PRACH preamble.
3. The method according to claim 2 , wherein the preamble sequence is arbitrarily selected by the UE or the preamble sequence is allocated from a base station (BS).
4. The method according to claim 1 , further comprising:
receiving a preamble sequence from a second UE,
wherein the at least one contention-based PUSCH block is determined based on the received preamble sequence of the PRACH preamble.
5. The method according to claim 4 , wherein the at least one contention-based PUSCH block is sequentially selected with respect to the preamble sequence.
6. The method according to claim 1 , wherein the data includes a radio resource control (RRC) connection request.
7. 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 receive Physical Uplink Shared Channel (PUSCH) configuration including information on at least one contention-based PUSCH resource block from the BS;
allocate the at least one contention-based PUSCH resource block for transmission of the data based on the PUSCH configuration; and
control the RF module to transmit the data to the BS,
wherein the at least one contention-based PUSCH resource block is determined based on a Physical Random Access Channel (PRACH) preamble.
8. The UE according to claim 7 , wherein the at least one contention-based PUSCH resource block is determined by the following equation,
Contention-based PUSCH resource block=(Preamble Sequence)mod N [Equation]
where N is a modulo operation, and N is a number of contention-based PUSCH resource blocks configured by the PUSCH configuration, and the Preamble Sequence is a sequence of the PRACH preamble.
9. The UE according to claim 8 , wherein the preamble sequence is arbitrarily selected by the UE or the preamble sequence is allocated from a base station (BS).
10. The UE according to claim 7 , wherein the processor is further configured to control the RF module to:
receive a preamble sequence from a second UE,
wherein the at least one contention-based PUSCH block is determined based on the received preamble sequence of the PRACH preamble.
11. The UE according to claim 10 , wherein the at least one contention-based PUSCH block is sequentially selected with respect to the preamble sequence.
12. The UE according to claim 10 , wherein the data includes a radio resource control (RRC) connection request.
