Each logical channel transports different types of traffic, and the name of the logical channel reflects the characteristic of the traffic it transport. RLC functions are performed by an RLC entity. The RLC entity is used for only one radio bearer. May 17, 2020 · 1.
Phasor diagrams for the series R-L-C circuit shown in Fig. 6.1 at three different frequencies i.e. (a) f < f r (b) f = f r and (c) f > f r with L and C kept constant are shown in Figs. 6.2 (a), (b) and (c) respectively.. For any frequency lower than resonant frequency f r, inductive reactance X L is lesser than the capacitive reactance X C and so the circuit behaves as a capacitive circuit.

The stored energy in C or L will force the current V t VC Once the switch (SW) is closed, after some oscillatory period, current And RLC PDUs can be categorized into RLC data PDUs and RLC control PDUs. RLC data PDUs in sub clause 6.1.2 are used by TM, UM and AM RLC entities to transfer upper layer PDUs (i.e. RLC SDUs). RLC control PDUs in sub clause 6.1.3 are used by AM RLC entity to perform ARQ procedures.
RLC AM PDU frame structure: iv) Add a RLC header to the RLC PDU. v) Send the RLC PDU to the next layer (MAC) < Summary of RLC UM Data Flow - Reception > i) The MAC layer passes the received RLC PDU to the RLC layer. ii) The RLC layer removes the RLC header from the PDU. iii). The RLC layer assembles the PDUs into a upper layer SDU. iv).

RLC control PDUs in sub clause 6.1.3 are used by AM RLC entity to perform ARQ procedures. 6.1.2 RLC data PDU. a) TMD PDU Jun 15, 2018 · Where, V B is the battery voltage and I o is the output current of the circuit. The value of t is the time (in seconds) at which the voltage or current value of the Inductor has to be calculated. RLC Circuit: A RLC circuit as the name implies will consist of a Resistor, Capacitor and Inductor connected in series or parallel. 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 Oct 11, 2020 · A SIMPLE explanation of an LC Circuit.
