[0004] In addition to the transmission of the UE's UL data, this method even causes a delay in the whole process
[0005] Specifically, if the UL data to be transmitted by the UE is data that requires low delay, when the delay is generated as described above, the service quality may deteriorate

Abstract

The present specification provides a method for transmitting uplink data (UL data) requiring a low latency in a wireless communication system. The method performed by a terminal comprises the steps of: receiving control information related to a contention based PUSCH zone from a base station; and transmitting uplink data to the base station on the basis of the received control information. The contention based PUSCH zone is a resource area where uplink data of the terminal can be transmitted without allocation of a UL grant from the base station. Further, in order to distinguish between kinds of specific procedures performed by the terminal, the control information includes procedure-distinguishing information allocated for each kind of the specific procedures.

Description

technical field [0001] The present specification relates to a method and apparatus for transmitting uplink (UL) data with low delay. Background technique [0002] In the case of a Long Term Evolution (LTE) system, in order to maximize resource utilization, a method of transmitting and receiving data through a resource allocation process based on BS scheduling is used. [0003] In this method, if the UE has data to transmit, it first requests allocation of UL resources to the BS, and only utilizes the UL resources allocated by the BS to transmit data. [0004] Apart from the transmission of the UE's UL data, this approach even causes delays throughout the process. [0005] Specifically, if UL data to be transmitted by the UE is data requiring low delay, service quality may deteriorate when delay is generated as described above. Contents of the invention [0006] technical problem [0007] An object of the present specification is to provide a method capable of causing a ...
