The LTE link layer protocols are optimized for low delay and low overhead and are simpler than their counterparts in UTRAN. The state-of-the-art LTE protocol design is the result of a careful cross-layer approach where the protocols interact with each other efficiently.

Radio Link Protocol (RLP) is an automatic repeat request fragmentation protocol used over a wireless (typically cellular) air interface.Most wireless air interfaces are tuned to provide 1% packet loss, and most Vocoders are mutually tuned to sacrifice very little voice quality at 1% packet loss. However, 1% packet loss is intolerable to all variants of TCP, and so something must be done to ... 5G NR Radio protocol architecture.

In the case of UMTS, the initial ... What is a radio link? A radio link is a wireless connection between two nodes, or radio units, in a data network. Each radio unit consits of a tranceiver and a highly directive antenna, typically operating at microwave frequencies in the range of 6 – 23 GHz.

The author team have been working on radio protocol standards in 3GPP (3rd Generation Partnership Project) for more than 10 years. Their major work is standardization of Layer2/3 radio protocols covering various 3GPP systems like UMTS, HSPA, LTE, and LTE-Advanced. Radio Link Monitoring (RLM) is one of the important procedures in LTE. It is used to keep track of the radio link condition so that appropriate steps can be taken if Radio Link Failure (RLF) is declared. The figure below (taken from T-doc R2-133859) captures the RLM process: From the same T-doc: PCell radio link…
Radio link control (RLC) is a layer 2 Radio Link Protocol used in UMTS and LTE on the Air interface. This protocol is specified by 3GPP in TS 25.322 for UMTS, TS 36.322 for LTE and TS 38.322 for 5G New Radio (NR). RLC is located on top of the 3GPP MAC-layer and below the PDCP-layer. The main tasks of the RLC protocol are: The LTE radio interface for 3GPP Release 8 was specified recently. This article describes the LTE link-layer protocols, which abstract the physical layer and adapt its characteristics to match the requirements of higher layer protocols.
