Abstract: A method for mitigation of lost resource allocation synchronization between a user equipment (UE) and an evolved Node B (eNodeB) during a Hybrid Automatic Repeat Request (HARQ) transmission and/or retransmission process is described. The method includes determining whether resource allocation is out of synchronization between a user equipment (UE) and an evolved Node B (eNodeB) during a hybrid automatic repeat request (HARQ) transmission and/or retransmission process. The method further includes mitigating a loss of resource allocation synchronization between the UE and the eNodeB during the HARQ transmission and/or retransmission process.

Abstract: The invention relates to interpreting the change in the increment of the RTP TS field as occurring either due to silence suppression for a voice flow or a change in sampling/ frame rate of a video flow. By interpreting this change correctly, the value of the TS_STRIDE field in robust header compression may be correctly calculated leading to efficient header compression performance. In one aspect, there is disclosed a method of improving ROHC between an Access Network AN having a compressor and an Access Terminal AT having a decompressor, comprising providing flow information to the compressor relating to a change in the increment of an RTP TS field of a header (302) ; determining the change in the increment of an RTP TS field as occurring either due to silence suppression or due to a change in a sampling/ frame rate (306) ; and taking appropriate action for TS_STRIDE .
