Which channel is used for uplink scheduling in 5G?

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 .

5G New Radio (NR) is the global standard for a unified, more capable 5G wireless air interface . It will deliver significantly faster and more responsive mobile broadband experiences, and extend mobile technology to connect and redefine a multitude of new industries.

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.

Broadcast Control Channel (BCCH ): It is used for transmitting system information from the network to UEs in a cell coverage. Prior to accessing the system, a UE needs to acquire the system information to find out the system configuration.29 Eki 2018
