3.3 Definitions
Activated uplink frequency: For a specific UE, an uplink frequency is said to be activated if the UE is allowed to
transmit on that frequency. The primary uplink frequency is always activated when configured while a secondary uplink
frequency has to be activated by means of an HS-SCCH order in order to become activated. Similarly, for a specific UE,
an uplink frequency is said to be deactivated if it is configured but disallowed by the NodeB to transmit on that frequency.
Configured uplink frequency: For a specific UE, an uplink frequency is said to be configured if the UE has received all
relevant information from higher layers in order to perform transmission on that frequency.
Primary uplink frequency: If a single uplink frequency is configured for the UE, then it is the primary uplink frequency.
In case more than one uplink frequency is configured for the UE, then the primary uplink frequency is the frequency on
which the E-DCH corresponding to the serving E-DCH cell associated with the serving HS-DSCH cell is transmitted.
The association between a pair of uplink and downlink frequencies is indicated by higher layers.
Secondary uplink frequency: A secondary uplink frequency is a frequency on which an E-DCH corresponding to a
serving E-DCH cell associated with a secondary serving HS-DSCH cell is transmitted. The association between a pair
of uplink and downlink frequencies is indicated by higher layers.

4 Uplink spreading and modulation
4.1 Overview
Spreading is applied to the physical channels. It consists of two operations. The first is the channelisation operation,
which transforms every data symbol into a number of chips, thus increasing the bandwidth of the signal. The number of
chips per data symbol is called the Spreading Factor (SF). The second operation is the scrambling operation, where a
scrambling code is applied to the spread signal.
With the channelisation, data symbols on so-called I- and Q-branches are independently multiplied with an OVSF code.
With the scrambling operation, the resultant signals on the I- and Q-branches are further multiplied by complex-valued
scrambling code, where I and Q denote real and imaginary parts, respectively.
4.2 Spreading
4.2.1 Dedicated physical channels
The possible combinations of the maximum number of respective dedicated physical channels which may be configured
simultaneously for a UE in addition to the DPCCH are specified in table 0. The actual UE capability may be lower than
the values specified in table 0; the actual dedicated physical channel configuration is indicated by higher layer
signalling. The actual number of configured DPDCHs, denoted Nmax-dpdch, is equal to the largest number of DPDCHs
from all the TFCs in the TFCS. N is not changed by frame-by-frame TFCI change or temporary TFC
max-dpdch
restrictions.

Figure 1 illustrates the principle of the spreading of uplink dedicated physical channels (DPCCH, DPDCHs, HS-
DPCCH, DPCCH2, E-DPCCH, E-DPDCHs, S-E-DPCCH). Figure 1.1 illustrates the principle of the spreading of
uplink S-DPCCH and S-E-DPDCHs.
ETSI
3GPP TS 25.213 version 16.0.0 Release 16 9 ETSI TS 125 213 V16.0.0 (2020-09)
In case of BPSK modulation , the binary input sequences of all physical channels are converted to real valued
sequences, i.e. the binary value "0" is mapped to the real value +1, the binary value "1" is mapped to the real value –1,
and the value "DTX" (HS-DPCCH only) is mapped to the real value 0.
In case of 4PAM modulation, the binary input sequences of all E-DPDCH and S-E-DPDCH physical channels are
converted to real valued sequences, i.e. a set of two consecutive binary symbols nk, nk+1 (with k mod 2 = 0) in each
binary sequence is converted to a real valued sequence following the mapping described in Table 0A.
In case of 8PAM modulation, the binary input sequences of all E-DPDCH and S-E-DPDCH physical channels are
converted to real valued sequences, i.e. a set of three consecutive binary symbols n , n , n (with k mod 3 = 0) in
k k+1 k+2
each binary sequence is converted to a real valued sequence following the mapping described in Table 0B.

The spreading operation is specified in subclauses 4.2.1.1 to 4.2.1.4 for each of the dedicated physical channels; it
includes a spreading stage, a weighting stage, and an IQ mapping stage. In the process, the streams of real-valued chips
on the I and Q branches are summed; this results in a complex-valued stream of chips for each set of channels.
As described in figure 1, the resulting complex-valued streams Sdpch, Sdpcch2, Shs-dpcch, Se-dpch and Ss-e-dpcch are summed
into a single complex-valued stream which is then scrambled by the complex-valued scrambling code S resulting in
dpch,n
the complex-valued signal S. As described in Figure 1.1, the resulting complex-valued streams S and S are
s-dpcch s-e-dpdch
summed into a single complex-valued stream which is scrambled by the same complex-valued scrambling code S
dpch,n
resulting in the complex-valued signal S'. The scrambling code shall be applied aligned with the radio frames, i.e. the
first scrambling chip corresponds to the beginning of a radio frame.
NOTE: Although subclause 4.2.1 has been reorganized in this release, the spreading operation for the DPCCH,
DPDCH remains unchanged as compared to the previous release.
4.2.1.1 DPCCH/DPDCH
Figure 1a illustrates the spreading operation for the uplink DPCCH and DPDCHs.

When the UE is configured in MIMO mode and transmitting two transport blocks, one with a set of E-DPDCHs and
another with a set of S-E-DPDCHs, the amplitude ratios A for the primary stream are modified to take the inter-stream

interference into account. Note that the amplitude ratios for the secondary stream are not modified. The amplitude ratios
A for the primary stream are then given by
