Zusammenfassung:A method can include wireless device operations, including receiving a trigger communication that identifies available random access resource units (RA RUs), the RA RUs being portions of transmission channel for a wireless system. In response to a back-off value and a number of available RA RUs, selecting or not selecting one RA RU as a transmission RA RU. In response to not selecting a transmission RA RU, monitoring for wireless responses following the trigger communication to determine unselected RA RUs, designating one unselected RA RUs as an alternate RA RU; and transmitting uplink data on the alternate RA RU. The unselected RA RUs comprise any RA RUs that remain after other wireless devices have selected RA RUs in response to the trigger communication. Corresponding devices and systems are also disclosed.
