What is logical channel group 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 is logical channel prioritization in 5g?
Logical Channel Prioritization Logical channels configured with equal priority should be served equally. – if the UE segments an RLC SDU from the logical channel, it shall maximize the size of the segment to fill the grant as much as possible; – UE should maximise the transmission of data.
What are the basic groups of logical channels?
3.3. According to the 3GPP standards [14], the logical channel types are: Broadcast Control Channel (BCCH), Paging Control Channel (PCCH), Common Control Channel (CCCH), Dedicated Control Channel (DCCH), Multi-cast Control Channel (MCCH), Dedicated Traffic Channel (DTCH), and Multicast Traffic Channel (MTCH).
What is the purpose of logical channels in LTE?
Logical channels define what type of information is transferred. These channels define the data-transfer services offered by the MAC layer. Data and signalling messages are carried on logical channels between the RLC and MAC layers.
What are the types of GSM logical channels?
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 the difference between a physical channel and a logical channel?
The Physical channels are determined by the timeslot, whereas the logical channels are determined by the information carried within the physical channel. These channels may either be used for user data (payload) or signalling to enable the system to operate correctly.
What is the difference between a physical channel and logical channel?
What is physical channel and logical channel?
Each time slot on a TDMA frame is called a physical channel. Physical channels can be used to transmit speech, data or signalling information. A physical channel may carry different messages, depending on information that is to be sent. These messages are called logical channels.
What is difference between a physical channel and logical channel?
What are the logical channels in GSM?
What are the LTE logical transport and physical channels?
LTE channel types There are three categories into which the various data channels may be grouped. Physical channels: These are transmission channels that carry user data and control messages. Logical channels: Provide services for the Medium Access Control (MAC) layer within the LTE protocol structure.

What are the different types of logical channels?
Logical channels can be classified into two general groups: Control Channels: Control channels are used for the transfer of control plane information only. The control channels offered by MAC are: A downlink channel for broadcasting system control information.
How are logical channels defined in 3GPP specification?
In 3GPP specifications, several types of data transfer services are offered by MAC. Each logical channel type is defined by the type of information that it transfers. Logical channels can be classified into two general groups: Control Channels: Control channels are used for the transfer of control plane information only.
What is the logical channel number in EDACS?
Logical Channel Number, or LCN, is primarly used to define frequencies in use on M/A-COM EDACS systems and LTR systems.
What’s the default BSR for logical channel group?
The default is 2.56 seconds. Interestingly, there is no direct relationship between the BSRs sent by the UE and how it processes a grant from eNB. Resource grants are allocated by the UE to radio bearers on a logical channel priority basis. Membership in a particular LCG is not relevant.
