Abstract

Disclosed are a method for transmitting/receiving an uplink signal between a base station and a terminal, and a device for supporting the same. More specifically, disclosed are a method for transmitting/receiving a signal between a terminal and a base station for the coexistence of terminals to which different transmission time intervals (TTIs) are applied when the terminals to which the different TTIs are applied send an uplink signal on the same resource, and a device for supporting the same.

Claims

1. A method of transmitting a physical uplink control channel (PUCCH) signal by a user equipment (UE) in a wireless communication system, the method comprising:

receiving a plurality PUCCH resource configurations comprising (i) a number of symbols used for a corresponding PUCCH signal, and (ii) symbol index information related to the corresponding PUCCH signal, respectively, via a higher layer signaling;

receiving downlink control information (DCI) related to a certain PUCCH resource configuration among the plurality of PUCCH resource configurations; and

transmitting the PUCCH signal based on the certain PUCCH resource configuration determined based on a combination of (i) the higher layer signaling and (ii) the DCI,

wherein a slot index related to the PUCCH signal is determined based on the DCI.

2. The method of claim 1, wherein a number of symbols used for the PUCCH signal is determined as 4 symbols or more than 4 symbols, based on the certain PUCCH resource configuration.

3. The method of claim 1, wherein the higher layer signaling is a radio resource control (RRC) signaling.
