The smallest resource unit for uplink transmissions is denoted a resource element and is defined in clause 5.2.2.

5.1.1 Physical channels

An uplink physical channel corresponds to a set of resource elements carrying information originating from higher layers and is the interface defined between TS 36.212 [3] and the present document TS 36.211.
The following uplink physical channels are defined:

– Physical Uplink Shared Channel, PUSCH

– Physical Uplink Control Channel, PUCCH

– Short Physical Uplink Control Channel, SPUCCH

– Physical Random Access Channel, PRACH

5.1.2 Physical signals

An uplink physical signal is used by the physical layer but does not carry information originating from higher layers. The following uplink physical signals are defined:

– Reference signal
