Cell Parameters (Advanced LTE FDD Downlink)

Additional Downlink parameters are described in Cell Specific Reference Signal (Advanced LTE FDD Downlink), Positioning Reference Signals (PRS) - (Advanced LTE FDD Downlink), Synchronization Signals (Advanced LTE FDD Downlink), and Power Relevant Parameters (Advanced LTE FDD Downlink).

1. Cell Parameters

Cell ID

Physical Layer Cell ID Group

Physical Layer Cell ID Sector

Number of Orthogonal Sequence

Antenna Port

Total number of Antennas

System Bandwidth

Total number of Resource Blocks

Total number of Occupied Sub-carriers

Subcarrier Spacing

Cyclic Prefix

Number of Subcarriers for Resource Block

Number of Symbols for Resource Block

Cell ID

Range: 0 to 503

Default: 1

Enter a value for the Cell ID. The software sets the values in the Physical Layer Cell ID Group and Physical Layer Cell ID Sector cells based on the Cell ID entry. Cell ID = [(3 x Physical Cell ID Group) + Physical Cell ID Sector]. See 3GPP TS 36.211.

Physical Layer Cell ID Group

Range: 0 to 167

Default: 0

The software sets this value based on the Cell ID entry. Cell ID = [(3 x Physical Cell ID Group) + Physical Cell ID Sector]. (See 3GPP TS 36.211.)

Physical Layer Cell ID Sector

Choice: 0 | 1 | 2

Default: 0

The software sets this value based on the Cell ID entry. Cell ID = [(3 x Physical Cell ID Group) + Physical Cell ID Sector]. (See 3GPP TS 36.211.)

Number of Orthogonal Sequence

Range: 0 to 2

When you set the value in the Physical Layer Cell ID Sector cell, the software sets the Number of Orthogonal Sequence to the corresponding value. (See 3GPP TS 36.211.)

Antenna Port

Choice: 0 | 1 | 2 | 3

Default: 0

In multi-antenna configurations, specify the antenna to be used for transmitting the downlink signal. The available selections are determined by the Total Number of Antennas setting.

Total number of Antennas

Choice: 1 Antenna | 2 Antennas | 4 Antennas

Default: 1 Antenna

Specify the total number of base station antennas.

For multiple signal generator configurations, set the Channel State parameter in the Fading section of the Carrier node to On to make this cell active. When the channel state is off, you must change the number of signal generators (for example, use a Quick Setup) to change the number of BS antennas.

System Bandwidth

Choice: 1.4 MHz (6RB) | 3 MHz (15RB) | 5 MHz (25RB) | 10 MHz (50RB) | 15 MHz (75RB) | 20 MHz (100RB)

Default: 5 MHz (25RB)

Double-click or use the drop-down menu to set the system bandwidth and number of Resource Blocks (RB).

Total number of Resource Blocks

The value in this cell is set by the software based on the System Bandwidth setting.

Total number of Occupied Sub-carriers

The value in this cell is set by the software based on the System Bandwidth setting. The center subcarrier is not used for downlink transmission, so the number of transmitted subcarriers is one less than the number of occupied subcarriers.

Subcarrier Spacing

Default: 15 kHz

Displays the subcarrier spacing for the downlink. Only 15 kHz spacing is available in this release.

Cyclic Prefix

Choice: Normal | Extended

Default: Normal

Double-click or use the drop-down menu to select a Normal or Extended cyclic prefix. The software sets the Number of Symbols for Resource Block based on the cyclic prefix selection.

Number of Subcarriers for Resource Block

Default: 12

Displays the number of consecutive subcarriers in a downlink resource block.

Number of Symbols for Resource Block

Default: 7 for Normal Cyclic Prefix; 6 for Extended Cyclic Prefix

Displays the number of consecutive OFDM symbols in a downlink slot.
