US 10,856,269 B2 · Method and apparatus for transmitting/receiving wireless signal in wireless communication system

Abstract

The present invention relates to a wireless communication system, and more particularly, to a method including receiving indication information related to a PUCCH resource set of a specific PUCCH format through system information, the PUCCH resource set comprising a first RB offset, receiving a PDCCH including a resource indicator RI through CCE, and transmitting the control information on the PUCCH, wherein an RB index of the PUCCH is determined based on the first RB offset and a second RB offset related to a first bit value of the RI, and wherein a CS index of the PUCCH is determined based on a combination of [a second bit value of the RI, a 1-bit value based on a starting CCE index of the PDCCH (hereinafter, a CCE-based 1-bit value)] in a CS index set, and an apparatus therefor.

Dependent claims

A method performed by a device in a wireless communication system, the method comprising:

receiving system information including information for indicating one of common physical uplink control channel (PUCCH) resource sets, wherein the indicated common PUCCH resource set is associated with a resource block (RB) offset;
receiving downlink control information (DCI) comprising scheduling information and a resource indicator (RI);
receiving a downlink data based on the scheduling information;
and
based on no dedicated PUCCH resource being configured, transmitting acknowledgement/negative acknowledgement (ACK/NACK) information for the downlink data using a PUCCH resource determined from the indicated common PUCCH resource set,
wherein an RB index of the PUCCH resource is determined based on the RB offset and a value related to the RI, and
wherein a cyclic shift (CS) index applied to a sequence for the PUCCH resource is determined based on the RI and a control channel element (CCE) index related to the DCI.

receive a downlink data based on the scheduling information, and
based on no dedicated PUCCH resource being configured, transmit acknowledgement/negative acknowledgement (ACK/NACK) information for the downlink data using a PUCCH resource determined from the indicated common PUCCH resource set,
wherein an RB index of the PUCCH resource is determined based on the RB offset and a value related to the RI, and
wherein a cyclic shift (CS) index applied to a sequence for the PUCCH resource is determined based on the RI and a control channel element (CCE) index related to the DCI.
