A wireless device may determine transmission parameters for data transmission based on configuration associated with control signaling. For example, the transmission parameters (e.g., transmission beam, transmission power, etc.) may be determined based on a selected spatial relation, among multiple spatial relations, corresponding to a control channel. ## Claims ### Claim 1 A method comprising: receiving, by a wireless device, downlink control information (DCI) scheduling an uplink transmission;
