LTE protocol stack

The protocol stack functions consist of the Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Radio Resource Control (RRC) . LTE is the latest generation of the 3GPP standards. The LTE standard specifies an IP-only network supporting data rates up to 150 Mbps.

The protocol stack is used to allow the combination of different protocols that each set the boundaries for a number of network activities . … These functions are all separated into separate ‘layers’ of data that all require a protocol to be transferred.

The protocol stack or network stack is an implementation of a computer networking protocol suite or protocol family . Some of these terms are used interchangeably but strictly speaking, the suite is the definition of the communication protocols, and the stack is the software implementation of them.
