CN-118176689-B - Wireless device, base station, and storage medium for uplink transmission

Abstract

A wireless device is capable of receiving first Downlink Control Information (DCI) including an activated Transmission Configuration Indicator (TCI) status code point indicating a TCI status and a second TCI status. The wireless device can receive a second DCI including a field indicating whether to transmit a transport block having one or more of the first TCI state and the second TCI state. The wireless device can transmit a repetition of the transport block based on the field.
