5G downlink physical channel corresponds to a set of resource elements carrying information originating from higher layers.<\/p>\n

Downlink Physical channels in 5G:<\/p>\n

-Physical downlink control channel (PDCCH): that carries DCI for downlink control information (DCI)<\/p>\n

-Physical Downlink Shared Channel (PDSCH): that carries the user data and System information\u00a0 for user<\/p>\n

-Physical broadcast channel (PBCH) which carries the necessary system information to enable a UE to access the 5G network.<\/p>\n

5G Uplink Physical channels<\/h3>\n

An uplink physical channel corresponds to a set of resource elements carrying information originating from higher layers.<\/p>\n

Uplink Physical channels are:<\/p>\n

-Physical Uplink Control Channel (PUCCH): Used for uplink control information, which includes: HARQ feedback acknowledgments, scheduling request, and downlink channel-state information\u00a0 for link adaptation.<\/p>\n

-Physical Uplink Shared Channel (PUSCH): Used for uplink data transmission (by a UE).<\/p>\n

-Physical Random Access Channel (PRACH): Used by a UE to request connection setup referred to as random access.<\/p>\n
