What are channels in LTE?
What is a Channel in LTE? The information flows between the different protocols layers are known as channels. These are used to segregate the different types of data and allow them to be transported across different layers.
How many different channels are there in LTE channel structure?
three different channel types
There are three different channel types defined in LTE – logical channels, transport channels, and physical channels, each associated with a service access point (SAP) between different layers. These channels are used by the lower layers of the protocol stack to provide services to the higher layers.
How many logical channels are there in LTE?
1.2 Logical Traffic Channels: Dedicated Traffic Channel (DTCH) – used for dedicated traffic for a particular UE. Multicast Traffic Channel (MTCH) – used to transmit Multicast data.
What is the purpose of logical channels in LTE?
A logical channel is defined by the type of information it carries and is generally classified as a control channel, used for transmission of control and configuration information necessary for operating an LTE system, or as a traffic channel, used for the user data.
What are the different types of logical channels?
There are three types of logical channels: traffic channels (TCHs), control channels (CCHs), and the cell broadcast channel (CBCH). The traffic channels are used to transmit user information (speech or data). The control channels are used to transmit control and signaling information.
What are the types of LTE channels?
What are the types of LTE channels? Logical channel – LTE-RLC layer passes data to the LTE-MAC layer as logical channels. Transport Channel – The LTE-MAC layer formats and send the logical channel data as transport channels. Physical channel – The LTE-PHY layer encodes the transport channel data to physical channels.
How many logical channel in LTE?
Traffic channels carry data in the user plane, while logical control channels carry signalling messages in the control plane. In LTE we have 7 logical channel in Downlink and 3 Logical channels in Uplink Control channel: In Downlink there are 4 Control channel which carried Common channel information as well as dedicated channel information
What is LTE Band 20?
Band 20 is an LTE operating frequency Band. LTE is designed to work across a number of frequency bands – E-UTRA operating bands- currently ranging from 450 MHz up to 3.8GHz.
