For SRB's mentioned default parameter values :
RLC configuration CHOICE
ul-RLC-Config
>t-PollRetransmit
>pollPDU
>pollByte
>maxRetxThreshold
dl-RLC-Config
>t-Reordering
>t-StatusProhibit
Logical channel configuration
priority
prioritisedBitRate
bucketSizeDuration
logicalChannelGroup
So is their any default parameters value for DRB for RLC AM mode in LTE for UL & DL?
