Abstract

The present invention relates to methods and arrangements for handling unreliable scheduling grants in a WCDMA-communication system. A user equipment detects that a received scheduling grant is unreliable and adjust its serving grant based on that information. The user equipment is also able to report continuously received unreliable grants as an event to the network, allowing the network to adapt its operation to reduce the unreliable grants.

Description

technical field

[0001] The present invention relates generally to communication systems and in particular to methods and arrangements for handling unreliable scheduling grants in WCDMA communication systems. Background technique

[0002] In WCDMA enhanced uplink, the Node B sends scheduling commands to the user equipment (UE) in every Transmission Time Interval (TTI), which can currently be 2 ms or 10 ms. Each user equipment maintains a serving grant (SG) by increasing or decreasing its transmission bit rate as dictated by the scheduling grant received from the network. This change of the transmission bit rate is in turn implemented by applying the selection of the Transport Format Combination (TFC) in the user equipment.

[0003] A Scheduling Grant or a Scheduling Grant message provides an indication to a user equipment from eg a Node B of a serving radio link set and a non-serving radio link set, about the maximum amount of uplink resources that the user equipment can use...
