Uplink transmission in a wireless communication system

A wireless device comprising:

• multiple panels;
• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
• receive, from a base station, configuration parameters of physical uplink control channel (PUCCH) resources of a cell, the PUCCH resources being grouped into a plurality of PUCCH resource groups each associated with a respective panel of the multiple panels;
• receive via a control resource set, a downlink control information (DCI) indicating an uplink grant;
• select, based on the control resource set, a PUCCH resource group from the plurality of PUCCH resource groups;
• determine a spatial relation information corresponding to a first PUCCH resource of the PUCCH resource group;
• and
• transmit, via a first panel of the multiple panels corresponding to the selected PUCCH resource group, an uplink transport block via the uplink grant based on the spatial relation information.
