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.
Read moreWhat are 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.
Read moreWhat are the physical channels?
A physical radio channel is a radio frequency or pair of frequencies that is allocated by the regulatory body to an agency for communication . Simply put, this means in direct radio to radio communication the same frequency may be used for reception and transmission.
Read moreWhat are the LTE logical transport and physical channels?
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 .

The Physical Downlink Control Channel (PDCCH) is used for downlink control information, mainly scheduling decisions, required for reception of PDSCH, and for scheduling grants enabling transmission on the PUSCH. The Physical Uplink Shared Channel (PUSCH) is the uplink counterpart to the PDSCH.
