Various aspects of the disclosure provide an intra-Node B unsynchronized serving cell change enabling the typical loss of packets resulting from such a procedure to be reduced or eliminated. In one example, when a UE ceases listening to a downlink channel from a first cell provided by a Node B and starts to configure its receiver to listen to a downlink channel from a second cell provided by the Node B, a continued incrementing of a sequence number may be stalled in the transmission of packets to the UE. That is, the TSN space may be stalled, such that HARQ retransmissions recur beyond the preconfigured maximum number of retransmissions, until the UE indicates that the serving cell change is complete. In another example, the transmission of packets to the UE from the first cell may be halted until the UE indicates that the serving cell change is complete. |
