`the first digit:
`
`1 presented to TSG for information;
`
`2 presented to TSG for approval;
`
`3 or greater indicates TSG approved document under change control.
`
`y
`
`the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
`updates, etc.

`Overview
`5.1
`The smallest resource unit for uplink transmissions is denoted a resource element and is defined in section 5.2.2.
`
`Physical channels
`5.1.1
`An uplink physical channel corresponds to a set of resource elements carrying information originating from higher
`layers and is the interface defined between 36.212 and 36.211. The following uplink physical channels are defined:
`
`- Physical Uplink Shared Channel, PUSCH
`
`- Physical Uplink Control Channel, PUCCH
`
`- Physical Random Access Channel, PRACH
`
`Physical signals
`5.1.2
`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:

`Physical uplink shared channel
`5.3
`The baseband signal representing the physical uplink shared channel is defined in terms of the following steps:
`
`-
`
`scrambling
`
`- modulation of scrambled bits to generate complex-valued symbols
`
`-
`
`transform precoding to generate complex-valued modulation symbols
`
`- mapping of complex-valued modulation symbols to resource elements
`
`- generation of complex-valued time-domain SC-FDMA signal for each antenna port
