Embodiment Construction

[0050] figure 1 A wireless communication system to which the present disclosure can be applied is shown. The wireless communication system may be referred to as an Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) or a Long Term Evolution (LTE) / LTE-A system.

[0051] The E-UTRAN includes at least one base station (BS) 20 that provides a user equipment (UE) 10 with a control plane and a user plane. The UE 10 may be fixed or mobile and may be referred to by another term such as a mobile station (MS), user terminal (UT), subscriber station (SS), mobile terminal (MT), wireless device, and the like. BS 20 is typically a fixed station that communicates with UE 10 and may be referred to by another term such as evolved Node B (eNB), base transceiver system (BTS), access point, and the like.

[0052] The BSs 20 are interconnected via the X2 interface. BS 20 is also connected to Evolved Packet Core (EPC) 30 through S1 interface, more specifically, to Mobility Management Entity ...

Abstract

Provided are a method for adjusting a contention window size in a wireless communication system and a terminal using the method. The method comprises: transmitting first data according to an autonomous uplink transmission (AUL) to a base station; transmitting second data according to a grant-based uplink transmission to the base station; receiving first ACK / NACK information for the first data andsecond ACK / NACK information for the second data through AUL-DFI; and adjusting a contention window size on the basis of at least one of the first ACK / NACK information and the second ACK / NACK information included in the AUL-DFI. When the first data includes only one transport block and the second data includes a plurality of transport blocks, if there is an ACK for at least one of the plurality oftransport blocks, the second ACK / NACK information is set to ACK, and if there are NACKs for all of the plurality of transport blocks, the second ACK / NACK information is set to NACK.

Description

technical field [0001] The present disclosure relates to wireless communication, and more particularly, to a method of adjusting contention window size in a wireless communication system and a device using the method. Background technique [0002] As more and more communication devices require more communication capacity, there is a need for improved mobile broadband communication over existing radio access technologies. In addition, Massive Machine Type Communication (MTC), which provides various services by connecting many devices and objects, is one of the main issues to be considered in next generation communication. Additionally, communication system design considering reliability / delay sensitive services / UEs is being discussed. The introduction of next-generation radio access technologies considering enhanced mobile broadband communication (eMBB), massive MTC (mMTC), and ultra-reliable low-latency communication (URLLC) is discussed. In this disclosure, for convenienc...
