Claim of US Patent No. 10,194,457

1. A method for proactive allocation of uplink transmission resources to a wireless device, wherein the wireless device transmits periodic uplink data traffic, the method being performed in a radio access node in a wireless communication system, the method comprising:estimating a transmission phase for the periodic uplink data traffic by, for two or more transmission periods, adjusting timing of an uplink transmission resource allocation for the wireless device in a subsequent transmission period depending on whether an uplink transmission resource allocated in a previous transmission period was used by the wireless device or not; and
proactively allocating uplink transmission resources to the wireless device, such that a timing of the proactively allocated uplink transmission resources matches the estimated transmission phase,
wherein estimating the transmission phase further comprises allocating a first and second uplink transmission resource in each transmission period, and adjusting a timing of the first and/or the second uplink transmission resource allocation depending on which of the uplink transmission resources allocated in a previous transmission period was used by the wireless device.
