What is logical channel prioritization in LTE?
What is logical channel prioritization in LTE?
In LCP, Prioritize Bit Rate (PBR) is added to each logical channel. Hence while filling the MAC PDU, first it will take and add the minimum data i.e PBR from all the channels into the MAC PDU. After that if there are any space left in MAC PDU, then it will fill according to the priority.
What are the logical channels through which Pbch is carried through?
Transport Channels
| Channel Name | Acronym | Downlink |
|---|---|---|
| Downlink Shared Channel | DL-SCH | X |
| Paging Channel | PCH | X |
| Multicast Channel | MCH | X |
| Uplink Shared Channel | UL-SCH |
What is prioritized bit rate?
To avoid starvation, while still serving the logical channels according to their priorities, in LTE a Prioritized Bit Rate (PBR) is configured by the eNodeB for each logical channel. The PBR is the data rate provided to one logical channel before allocating any resource to a lower-priority logical channel.
What are the 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).
What are the logical channels carried through Harq?
What are the Logical Channels carried through HARQ? Ans:CCCH, DCCH and DTCH logical channels.
What are the types of logical channels in GSM architecture?
There are two types of GSM logical channels, called Traffic CHannels (TCH) and Control CHannels (CCH). Traffic channels carry digitally encoded user speech or user data and have identical functions and formats on both the forward and reverse link.

What is logical channel in GSM?
How many logical channels are there in LTE?
Different channels provide interfaces to the higher layers of the LTE protocol stack and enables an orderly and defined segregation of the data. There are three types of channels into which the various data channels are grouped.
What are the types of logical channels in a GSM structural architecture?
In GSM logical channels (see Figure 7.4) are used to carry traffic and control information. 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).
What are the control channel groups in GSM?
In GSM networks, Control Channels are divided into three categories: Broadcast Channel (BCH), Common Control Channel (CCCH), and Dedicated Control Channel (DCCH).
