3.1 Definitions

For the purposes of the present document, the following definitions apply:

Assisting secondary serving HS-DSCH Cell: In addition to the serving HS-DSCH cell, a cell in the secondary downlink frequency, where the UE is configured to simultaneously monitor a HS-SCCH set and receive HS-DSCH if it is scheduled in that cell.

Assisting serving HS-DSCH Cell: In addition to the serving HS-DSCH cell, a cell in the same frequency, where the UE is configured to simultaneously monitor a HS-SCCH set and receive HS-DSCH if it is scheduled in that cell.

Cell group: A group of (one, two or three) Multiflow mode cells that have the same CPICH timing. The cells that belong to a cell group are indicated by higher layers.

Enhanced performance requirements type 1: This defines performance requirements which are optional for the UE. The requirements are based on UEs which utilise receiver diversity.

Enhanced performance requirements type 2: This defines performance requirements which are optional for the UE, The requirements are based on UEs which utilise a chip equaliser receiver structure.

Enhanced performance requirements type 3: This defines performance requirements which are optional for the UE, The requirements are based on UEs which utilise a chip equaliser receiver structure with receiver diversity.

Enhanced performance requirements type 3i: This defines performance requirements which are optional for the UE, The requirements are based on UEs which utilise an interference-aware chip equaliser receiver structure with receiver diversity.

Power Spectral Density: The units of Power Spectral Density (PSD) are extensively used in this document. PSD is a function of power versus frequency and when integrated across a given bandwidth, the function represents the mean power in such a bandwidth. When the mean power is normalised to (divided by) the chip-rate it represents the mean energy per chip. Some signals are directly defined in terms of energy per chip, (DPCH_Ec, Ec, OCNS_Ec and S-CCPCH_Ec) and others defined in terms of PSD (Io, Ioc, Ior and Îor). There also exist quantities that are a ratio of energy per chip to PSD (DPCH_Ec/Ior, Ec/Ior etc.). This is the common practice of relating energy magnitudes in communication systems.
It can be seen that if both energy magnitudes in the ratio are divided by time, the ratio is converted from an energy ratio to a power ratio, which is more useful from a measurement point of view. It follows that an energy per chip of X dBm/3.84 MHz can be expressed as a mean power per chip of X dBm. Similarly, a signal PSD of Y dBm/3.84 MHz can be expressed as a signal power of Y dBm.

Maximum Output Power: This s a measure of the maximum power the UE can transmit (i.e. the actual power as would be measured assuming no measurement error) in a bandwidth of at least (1+  times the chip rate of the radio access mode. The period of measurement shall be at least one timeslot.For DC-HSUPA the maximum output power is defined by the sum of the broadband transmit power of each carrier in the UE.

Mean power: When applied to a W-CDMA modulated signal this is the power (transmitted or received) in a bandwidth of at least (1+  times the chip rate of the radio access mode. The period of measurement shall be at least one timeslot unless otherwise stated.

Multiflow mode: The UE is configured in Multiflow mode when it is configured with assisting serving HS-DSCH cell.

Nominal Maximum Output Power: This is the nominal power defined by the UE power class.

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.

RRC filtered mean power: The mean power as measured through a root raised cosine filter with roll-off factor  and a bandwidth equal to the chip rate of the radio access mode.

NOTE 1: The RRC filtered mean power of a perfectly modulated W-CDMA signal is 0.246 dB lower than the mean power of the same signal.

NOTE 2: The roll-off factor  is defined in section 6.8.1.

Secondary serving HS-DSCH cell(s): In addition to the serving HS-DSCH cell, the set of cells where the UE is configured to simultaneously monitor an HS-SCCH set and receive the HS-DSCH if it is scheduled in that cell. There can be up to 7 secondary serving HS-DSCH cells.

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.

Time reference cell: The (Serving or Assisting Serving, but not Secondary Serving or Assisting Secondary Serving) HS-DSCH cell that carries the HS-PDSCH acting as the time reference for the uplink HS-DPCCH when in Multiflow mode. There is one and only one Time reference cell.

Throughput: Number of information bits per second excluding CRC bits successfully received on HS-DSCH by a HSDPA capable UE.

1st secondary serving HS-DSCH cell: If the UE is configured with two uplink frequencies, the 1st secondary serving HS-DSCH cell is the secondary serving HS-DSCH cell that is associated with the secondary uplink frequency. If the UE is configured with a single uplink frequency, the 1st secondary serving HS-DSCH cell is a secondary serving HS-DSCH cell whose index is indicated by higher layers.
