What is LTE stack protocol?
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.
What are LTE protocols?
What are LTE protocols & specifications?
- Air Interface Physical Layer.
- GPRS Tunnelling Protocol User Plane (GTP-U)
- GTP-U Transport.
- Medium Access Control (MAC)
- Non-Access-Stratum (NAS) Protocol.
- Packet Data Convergence Protocol (PDCP)
- Radio Link Control (RLC)
- Radio Resource Control (RRC)
Which protocol is responsible for HARQ and scheduling?
Finally, the Medium Access Control (MAC) sublayer provides Hybrid-ARQ (HARQ) and is responsible for the functionality that is required for medium access, such as scheduling operation and random access.
What is protocol stack development?
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.
What are LTE layers?
As defined by 3GPP, LTE Layer 2 structure consists of PDCP/RLC/MAC layers. Transport channels are located between the physical layer and MAC layer. MAC multiplexes RLC links and manages scheduling and priority handling via logical channels. The diagrams below show the structure for the downlink and uplink of Layer 2.
What is LTE call flow?
With Long Term Evolution (LTE) comes a myriad of new and exciting attributes. One of these is the LTE call flow itself. In fact, call flow and signaling is unique for LTE, and is driven by 3GPP standards. Call flow is how signaling and sessions are created across an LTE network.
What is LTE frame structure?
In LTE, DL and UL transmissions are organized into radio frames of 10 ms each. Each frame is divided into ten equally sized subframes. The duration of each subframe is 1 ms. Moreover, each subframe is further divided into two equally sized time slots, that is, each slot is 0.5 ms.
Does LTE use TCP?
Abstract. One of the implementation of a wireless network is based on mobile broadband technology Long Term Evolution (LTE). The majority of the Internet connections in the world happen using the TCP (Transmission Control Protocol) due to the TCP’s reliability in transmitting packets in the network.
What is the function of RLC in LTE?
The main tasks of the RLC protocol are: Transfer of upper layer Protocol Data Units (PDUs) in one of three modes: Acknowledged Mode (AM), Unacknowledged Mode (UM) and Transparent Mode (TM) Error correction through ARQ (only for AM data transfer) Concatenation, segmentation and reassembly of RLC SDUs (UM and AM)
Why protocol stack is required?
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.
What OSI layer is LTE?
layer 2
This chapter discusses a long term evolution (LTE) air interface by describing three protocols in a data link layer, layer 2 of the OSI model. The medium access control (MAC) protocol schedules all the transmissions that are made on the LTE air interface and controls the low-level operation of the physical layer.

What is LTE protocol?
With its architecture based on Internet Protocol (IP), unlike many other cellular internet protocols, LTE is a high-speed connection that supports browsing websites, VoIP , and other IP-based services. LTE can theoretically support downloads at 300 megabits per second or more.
LTE User plane layer consists of upper layers, NAS, PDCP, RLC, MAC, PHY and RF. LTE Control plane layer covers upper layers, NAS, RRC , PHY and RF. Following figure depicts LTE protocol stack with main functions of each layer.
What is a stack protocol?
