  • Publication number: 20100279679
    Abstract: A network comprising a component configured to update an active set (AS) of cells based on a collective consideration of a plurality of cell measurement reports received during radio reconfiguration. Also included is a user equipment (UE), comprising a component configured such that the UE combines a plurality of cell measurement reports triggered briefly before and/or during radio reconfiguration, the combined measurement report used to update an AS of cells. Also included is a method comprising transmitting a radio bearer reconfiguration message, receiving a plurality of cell measurement reports, receiving a radio bearer reconfiguration complete message, and updating a plurality of AS cells using the combined cell measurement reports. Also included is a method comprising receiving a radio bearer reconfiguration message, obtaining a plurality of cell measurement reports, and sending a combined cell measurement report based on the cell measurement reports.

  • Publication number: 20100202389
    Abstract: A method is provided for acknowledging a semi-persistent scheduling (SPS) uplink resource release. The method comprises receiving an SPS resource release signal over a physical downlink control channel in a Downlink Control Information (DCI) format 1A. The signal includes an indicator that indicates that the signal pertains to at least one of an uplink resource release and a downlink resource release. The method further comprises sending an acknowledgement to confirm the release of the resource.

  • Publication number: 20100195605
    Abstract: A user agent comprising a processor enabled to configure the user agent to adjust a discontinuous reception (DRX) start offset when a downlink assignment is one of configured and reconfigured. The DRX start offset is adjusted to satisfy the equation (10*SFNstart time+subframestart time)modulo(Long DRX Cycle)=DRX start offset.

  • Publication number: 20100075691
    Abstract: A method is provided for improving reliability in semi-persistent scheduling activation/reactivation is provided. The method includes a user agent receiving a first data element from an access device specifying at least one first transport block size. The method further includes the user agent deriving a second transport block size based on a second data element received from the access device. The method further includes the user agent comparing the first transport block size with the second transport block size. The method further includes, when the first transport block size differs from the second transport block size, the user agent ignoring the received semi-persistent scheduling activation/reactivation data.
