    Abstract: A Global System for Mobile Communications (GSM) network supports multi-carrier operation on the downlink and/or uplink for a mobile station. The mobile station receives an assignment of multiple carriers for a first link in the GSM network, receives an assignment of at least one carrier for a second link in the GSM network, and exchanges data with the GSM network via the multiple carriers for the first link and the at least one carrier for the second link. The first link may be the downlink and the second link may be the uplink, or vice versa. The mobile station may receive data on multiple carriers at the same time for multi-carrier operation on the downlink. The mobile station may transmit data on multiple carriers at the same time for multi-carrier operation on the uplink.

    Abstract: Systems and methodologies are described that facilitate handing over mobi le device communications in a wireless network from a source base station to a target base station without using a random access channel (RACH). In this regard, the source base station can request shared data bandwidth resources from the target base station on behalf of the mobile device and assign the resources to the mobile device. The mobile device can calculate a timing dif ference between the source and target base stations and can handover communi cations by transmitting over the shared data bandwidth using the timing diff erence to generally provide correct timing for the transmission. To this end , the target base station can have transmission time intervals where it allo ws transmitting with an extended cyclic prefix to ensure more reliable hando ver for the mobile device.
