For 10 Gbps UL, the RLC layer needs to generate approximately 833 L1 fields every 1 ms (assuming 1500 byte PDCP PDU). LTE RLC header further imposes serial processing. The E bit is used to indicate the presence of additional L1 fields. An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC. LTE RLC Sub Layer Functions (Work of the RLC protocol in LTE): Main task of LTE RLC sub layer is transfer PDUs in three modes of LTE upper layer. RLC Sub Layer Functions Protocol Data Units (PDUs) Transfer in upper layer any of three modes: Acknowledged Mode (AM), Unacknowledged Mode (UM) and Transparent Mode (TM) We recall from the previous tutorial about series RLC circuits that the voltage across a series combination is the phasor sum of V R, V L and V C. Then if at resonance the two reactances are equal and cancelling, the two voltages representing V L and V C must also be opposite and equal in value thereby cancelling each other out because with It covers 5G NR RLC modes (TM mode, UM mode, AM mode), data structures (TMD, UMD, AMD), RLC PDUs (TMD PDU, UMD PDU, AMD PDU), data transfers (TM, UM and AM) and RRC parameters which defines RLC layer.

The RLC layer is present on top of the medium access control (MAC) layer and beneath other higher layers such as RRC (radio resource control) and PDCP (packet data convergence protocol) in the LTE protocol stack. PDCP, RLC, MAC-layers together make up LTE Layer 2. RLC acts as an interface between PDCP and MAC layers and provides services to both.

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 RLC layer assembles the PDUs into a upper layer SDU. iv).

RLC(Radio Link Control) submodular tested on the hardware is given, and the results show that the designed architecture and interface can meet the demand of LTE system. Categories and Subject Descriptors C.0[Systems Application Architecture]: Miscellaneous; D.3.2[Software engineering]: System architecture design, performance measures RLC (radio link control) is a layer 2 protocol of LTE used for reliable transmission of data packets in communication networks. This protocol operates in three modes, namely, transparent mode (TM), unacknowledged mode (UM), and acknowledged mode (AM). RLC submits these RLC PDUs (MAC SDUs) to the MAC layer. RLC Segmentation: If an RLC SDU is large, or the available radio data rate is low (resulting in small transport blocks), the RLC SDU may be split among several RLC PDUs. If the RLC SDU is small, or the available radio data rate is high, several RLC SDUs may be packed into a single PDU. Radio link control (RLC) is a layer 2 Radio Link Protocol used in UMTS and LTE on the Air interface.
