4 Frame structure
Throughout this specification, unless otherwise noted, the size of various fields in the time domain is expressed as a
number of time units T = 1()15000× 2048 seconds.
s
Downlink and uplink transmissions are organized into radio frames with T = 307200×T = 10 ms duration. Two radio
f s
frame structures are supported:
- Type 1, applicable to FDD,
- Type 2, applicable to TDD.
4.1 Frame structure type 1
Frame structure type 1 is applicable to both full duplex and half duplex FDD. Each radio frame is
T = 307200⋅T = 10 ms long and consists of 20 slots of length T = 15360⋅T = 0.5 ms , numbered from 0 to 19. A
f s slot s
subframe is defined as two consecutive slots where subframe i consists of slots 2ai nd 2i +1.
ETSI
3GPP TS 36.211 version 9.1.0 Release 9 10 ETSI TS 136 211 V9.1.0 (2010-04)
For FDD, 10 subframes are available for downlink transmission and 10 subframes are available for uplink transmissions
in each 10 ms interval. Uplink and downlink transmissions are separated in the frequency domain. In half-duplex FDD
operation, the UE cannot transmit and receive at the same time while there are no such restrictions in full-duplex FDD.

Figure 4.1-1: Frame structure type 1.
4.2 Frame structure type 2
Frame structure type 2 is applicable to TDD. Each radio frame of length T = 307200⋅T = 10 ms consists of two half-
f s
frames of length 153600⋅T = 5 ms each. Each half-frame consists of five subframes of length 30720⋅T = 1 ms . The
s s
supported uplink-downlink configurations are listed in Table 4.2-2 where, for each subframe in a radio frame, 'D'
denotes the subframe is reserved for downlink transmissions, 'U' denotes the subframe is reserved for uplink
transmissions and 'S' denotes a special subframe with the three fields DwPTS, GP and UpPTS. The length of DwPTS
and UpPTS is given by Table 4.2-1 subject to the total length of DwPTS, GP and UpPTS being equal
to 30720⋅T = 1 ms . Each subframe i is defined as two slots, 2ai nd 2i +1 of length T = 15360⋅T = 0.5 ms in each
s slot s
subframe.
Uplink-downlink configurations with both 5 ms and 10 ms downlink-to-uplink switch-point periodicity are supported.
In case of 5 ms downlink-to-uplink switch-point periodicity, the special subframe exists in both half-frames.
In case of 10 ms downlink-to-uplink switch-point periodicity, the special subframe exists in the first half-frame only.
Subframes 0 and 5 and DwPTS are always reserved for downlink transmission. UpPTS and the subframe immediately
following the special subframe are always reserved for uplink transmission.

5.1 Overview
The smallest resource unit for uplink transmissions is denoted a resource element and is defined in section 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 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
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

5.2 Slot structure and physical resources
5.2.1 Resource grid
UL RB UL
The transmitted signal in each slot is described by a resource grid of N N subcarriers and N SC-FDMA

symbols. The resource grid is illustrated in Figure 5.2.1-1. The quantity N depends on the uplink transmission

N ≤ N ≤ N

min, UL max,UL
where 6N = and N = 110 are the smallest and largest uplink bandwidths, respectively, supported by the

current version of this specification. The set of allowed values for N is given by [7].
RB
The number of SC-FDMA symbols in a slot depends on the cyclic prefix length configured by the higher layer
parameter UL-CyclicPrefixLength and is given in Table 5.2.3-1.

5.3 Physical uplink shared channel
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 symbols
- mapping of complex-valued symbols to resource elements
- generation of complex-valued time-domain SC-FDMA signal for each antenna port

5.3.1 Scrambling
The block of bits b(0),.,b(M −1) , where M is the number of bits transmitted on the physical uplink shared
bit bit
channel in one subframe, shall be scrambled with a UE-specific scrambling sequence prior to modulation, resulting in a
~ ~
block of scrambled bits b (0),.,b (M −1) according to the following pseudo code
bit
Set i = 0
while i < M
bit
if b(i) = x // ACK/NACK or Rank Indication placeholder bits
~
b (i) =1
else
if b(i) = y // ACK/NACK or Rank Indication repetition placeholder bits
~ ~
b (i) = b (i −1)
else  // Data or channel quality coded bits, Rank Indication coded bits or ACK/NACK coded bits
~
b (i) =()b(i) + c(i) mod 2
end if
end if
i = i + 1
end while

The block of scrambled bits b (0),.,b (M −1) shall be modulated as described in Section 7.1, resulting in a block of

the index l , starting with the first slot in the subframe.
