40、efinitions 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 ord
41、er 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 recei
42、ved 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 prim
43、ary 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 fr
44、equency 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. ETSI ETSI TS 125 213 V14.0.0 (2017-04)83GPP TS 25.213 versi
45、on 14.0.0 Release 144 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 numb
46、er 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 sc
47、rambling 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 dedi
48、cated 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 actu
49、al number of configured DPDCHs, denoted Nmax-dpdch, is equal to the largest number of DPDCHs from all the TFCs in the TFCS. Nmax-dpdchis not changed by frame-by-frame TFCI change or temporary TFC restrictions.
