Abstract

See full text

Technology for initiating a random access procedure by a wireless device after extended access barring (EAB) is disclosed. The wireless device can release a bar on the wireless device. The bar can prevent the wireless device from accessing a node using EAB. The wireless device can count a random backoff time using a random backoff timer. The random backoff time can include a random time between zero and a maximum backoff time period. The wireless device can transmit a random access channel (RACH) message (including physical random access channel (PRACH) preamble) from the wireless device to the node to initiate a random access procedure after the expiry of the random backoff timer.
