42、 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 deac
43、tivated 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. P
44、rimary 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 asso
45、ciated 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 seco
46、ndary serving HS-DSCH cell is transmitted. The association between a pair of uplink and downlink frequencies is indicated by higher layers. ETSI ETSI TS 125 213 V15.0.0 (2018-07)83GPP TS 25.213 version 15.0.0 Release 154 Uplink spreading and modulation 4.1 Overview Spreading is applied to the physic
47、al 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 scrambli
48、ng 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-
49、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 th
