It stands for Power Saving Mode and it means as it literally says. It is a specially kind of UE status that can minimize the energy consumption that is supposed to be even lower than normal idle mode energy consumption.
Similar to power-off, but the UE remains registered with the network
No need to re-attach or re-establish PDN connections.
A UE in PSM is not immediately reachable for mobile terminating services.

LTE: What type of data is considered for transparent mode (TM) transmission in LTE RLC ?

RLC is one of the L2 layer in LTE radio protocol stack. It does many functions such as segmentation, re-assembling and along with that it supports various transmissions mode like transparent mode, acknowledgement mode and un-acknowledgement mode.
