Method and device for executing multi-beam-based scheduling request in wireless communication

An operation method of a wireless device, the method comprising:

• receiving, from a base station, multi-beam scheduling request configuration information comprising first scheduling request configuration index information for a first physical uplink control channel (PUCCH) resource, and second scheduling request configuration index information for a second physical uplink control channel (PUCCH) resource, wherein each of the first scheduling request configuration index information and the second scheduling request configuration index information is associated with a corresponding PUCCH resource index information;
• and
• transmitting, to the base station, a first scheduling request using the first PUCCH resource and a second scheduling request using the second PUCCH resource, in one or more symbols in one slot through a new radio (NR) carrier having a subcarrier spacing of 2n*15 kHz, where n is 0 or a natural number greater than 0, wherein the first scheduling request is not same as the second scheduling request, and wherein the first PUCCH resource is not same as the second PUCCH resource,
• wherein the first and second PUCCH resources are configured based on the multi-beam, wherein the first and second PUCCH resources are mapped to the multi-beam on one-to-one basis, and
• wherein the scheduling requests are transmitted in a specific uplink radio frame, and retransmission is performed with the time duration of a subframe Np, and a transmission position in the subframe is arranged in the first half or the second half of the subframe.

A user equipment, the user equipment comprising:

• a transmitter;
• a receiver;
• and
• a controller which controls the transmitter and the receiver to:
• receive, from a base station, multi-beam based scheduling request configuration information comprising first scheduling request configuration index information for a first physical uplink control channel (PUCCH) resource and second scheduling request configuration index information for a second physical uplink control channel (PUCCH) resource, wherein each of the first scheduling request configuration index information and the second scheduling request configuration index information is associated with a corresponding PUCCH resource index information;
• and
• transmit, to the base station, a first scheduling request using the first PUCCH resource and a second scheduling request using the second PUCCH resource, in one or more symbols in one slot through a new radio (NR) carrier having a subcarrier spacing of 2n*15 kHz, where n is 0 or a natural number greater than 0, wherein the first scheduling request is not same as the second scheduling request, and wherein the first PUCCH resource is not same as the second PUCCH resource,
• wherein the first and second PUCCH resources are configured based on the multi-beam,
• wherein the first and second PUCCH resources are mapped to the multi-beam on one-to-one basis, and
• wherein the scheduling requests are transmitted in a specific uplink radio frame, and
• retransmission is performed with the time duration of a subframe Np, and a transmission position in the subframe is arranged in the first half or the second half of the subframe.
