Abstract
Wireless communication devices, systems, and methods for establishing latency-critical services. When a mobile station attempts to transmit a packet on a contention-based multiple-access radio channel without a prior reservation of channel resources, the mobile station notifies the base station of its attempt to randomly access the channel. The notification is performed on dedicated channel resources. Upon receipt of the notification of a mobile station's access attempt, the base station can know that a mobile station is the origin of the colliding packets, and can therefore correctly manage the retransmission of packets not received.
