    摘要： A method and apparatus for reducing handover interruptions when a mobile device executes handover including a random access procedure is described herein. When handover is desirable, a time offset associated with a random access opportunity is determined. The time offset relates the timing of the next random access opportunity to the frame timing of a target access point. Based on the time offset, a network element, e.g., the mobile device, a serving access point, or a mobility management entity, determines a handover start time. Handover is executed at the determined start time to generally align the beginning of the handover execution with the beginning of the next random access opportunity, and therefore, to reduce handover interruption.

    摘要： The present invention relates to methods and apparatuses (radio base station and UE) for enabling a UE to perform a contention-based random access. According to embodiments of the present invention, a non-dedicated random access preamble identifier is determined by a radio base station and the determined preamble is transmitted in a message to the UE which selects a non-dedicated random access preamble based on the received preamble identifier and performs a contention-based random access using the selected preamble.

    摘要： A method (500) for use in a user terminal (120, 130) in a cellular communications system (100). According to the method, the user terminal applies a first timing advance value (505) to its transmissions to a controlling node (140), and the user terminal (120, 130) requests communication with the controlling node (140) in a contention based procedure by transmitting an access request (MSG 1), in response (515) to which the controlling node transmits an initiation message (MSG 2) along with (520) a second timing advance value. According to the method (500), the user terminal (120, 130) uses (530) the first timing advance value if the user terminal loses the contention based procedure, i.e. if the controlling node subsequently continues the initiated communication with said other user terminal.

    摘要： In a method and a device for requesting Channel Quality Indication (CQI) reports from a mobile station of a cellular radio system, the CQI reports are requested in response to a measured Block Error Rate (BLER) of transmissions from the mobile station. In accordance with one embodiment of the present invention a CQI report is requested if the BLER of the mobile station is above a predetermined threshold value C. The threshold value C can be set to a value related to the BLER target. In particular the value C can be set to the same value or as a value close the BLER that is targeted to try to adapt the CQI report request to how well the base station knows the channel. It can also be set higher or lower to also consider how much CQI reporting the base station estimates can be afforded when it comes to uplink resources and uplink grant signaling in the downlink.

    摘要： In at least one embodiment taught herein, the point in a packet transmission sequence space at which hyper frame numbers are incremented is changed at least temporarily as part of handover processing, where a mobile station (12) is handed over from a source cell to a target cell. More particularly, in at least one embodiment, changing the triggering point, e.g., changing the transmission sequence number at which HFNs are incremented, is done in a manner that delays a next incrementing of the HFN for a radio bearer that was handed over, therefore giving additional time for the mobile station (12) and the handover target base station (16) to ensure synchronization in the face of possible packet losses in the source and/or target cells arising during the handover event.
