Method utilized in a base station, and base station thereof, for optimizing random access procedures

摘要

A method utilized in a mobile device (110) includes: transmitting a random access (RA) preamble to a base station (105a); receiving a control message including downlink (DL) data arrival from the base station (105a); transmitting a scheduled transmission message to the base station (105a) when an RA response from the base station (105a) is received and then starting a contention resolution timer; and before the contention resolution timer expires, transmitting a scheduling request message to the base station (1 05a).
