What are logical channels between MS and BTS?

Logical channels between a Mobile Station (MS) and a Base Transceiver Station (BTS) are channels that facilitate the transmission of data and control information. They include dedicated channels, such as the Traffic Channel (TCH) for user data and the Signaling Channel (SCH) for control messages. Additionally, common channels like the Broadcast Control Channel (BCCH) and Random Access Channel (RACH) enable essential communication for network access and information dissemination. These channels are crucial for ensuring efficient and organized communication in mobile networks.
