3.1.2.2 Sector A sector is an area covered by antennas. A sector is added by running the ADD SECTOR command. Each sector uses one or more radio carriers to provide coverage. A sector can be omnidirectional or directional, depending on the antenna type. l
Omnidirectional An omnidirectional sector uses omnidirectional antennas to provide 360° coverage with the antenna at the center. In light-traffic areas, the deployment of omnidirectional sectors means fewer antennas need to be deployed, which reduces equipment cost.
l
Directional A directional sector uses directional antennas to provide coverage. Each directional antenna covers a 60° or 120° sector area, depending on whether there are six or three sectors configured on the gNodeB. The azimuth of each sector is slightly over 60 or 120 degrees in actual scenarios so that the sectors can overlap to ensure seamless coverage. In heavy-traffic areas, the deployment of directional sectors supports more traffic volume. Directional sectors allow for greater flexibility in area and sector planning.
3.1.2.3 Sector Equipment Sector equipment is a set of antennas that are used to provide coverage for the same sector. A sector is linked to a set of antennas comprising a specific piece of sector equipment by running the ADD SECTOR and ADD SECTOREQM commands.
3.1.2.4 RF Equipment RF equipment is a set of RF processing units, such as remote radio units (RRUs) or active antenna units (AAUs). RF equipment is added and associated with CPRI ports on baseband processing units (BBPs) by running the ADD RRUCHAIN and ADD RRU commands.
3.1.2.5 Baseband Equipment A set of baseband equipment consists of one or more BBPs. A BBP is added by running the ADD BRD command. It can be added to a piece of baseband equipment by running the ADD BASEBANDEQM command. The baseband equipment for NR must support both uplink and downlink transmissions.
3.1.2.6 NR DU Cell TRP An NR DU cell transmission reception point (TRP) specifies the baseband equipment used by a cell. If no baseband equipment is specified for the NR DU cell TRP, the BBP directly connected to the RRU or AAU is used by default. An NR DU cell TRP is added by running the ADD NRDUCELLTRP command. Each common cell corresponds to only one NR DU cell TRP.
3.1.2.7 NR DU Cell Coverage Area An NR DU cell coverage area refers to a radio coverage area of an NR DU cell. You can run the ADD NRDUCELLCOVERAGE command to add an NR DU cell coverage area.

3.1.3.1 Common Cell A common cell is a cell that is established in a sector served by an RF module. The cell shown in Figure 3-2 is a common cell. Figure 3-2 Common cell
3.1.3.2 Combined-RRU Cell A combined-RRU cell is served by two RRUs connected to the same antenna to cover the same area. This networking applies only to NR SUL (supplementary uplink) cells. SUL cells supports combination of 1T2R or 2T2R RRUs. Figure 3-3 Combined-RRU-sector cell (using 2T2R RRUs as an example)
If combination of RRUs in star topology applies to three SUL sectors, six CPRI ports are required. If the baseband processing unit (BBP) cannot provide enough CPRI ports, cascading networking or LNR CPRI MUX networking is an option. In cascading networking, the fiber optic cable between two RRUs to be cascaded must be less than 100 m. Two combined RRUs must be connected to the same BBP.
3.1.3.3 Cells in Multi-Carrier Sectors In this scenario, cells working on different frequencies are set up in a single sector, as shown in Figure 3-4. This solution helps to expand system capacity without having to deploy additional base stations. Figure 3-4 Cells in a multi-carrier sector

Multi-carrier sectors are used in densely populated areas where traffic increases rapidly, such as exhibition centers, airport waiting areas, shopping malls, central business districts, and high-end residential areas. For details about carrier specifications, see RRU technical descriptions in 3900 & 5900 Series Base Station Product Documentation.
3.1.3.4 Uplink and Downlink Decoupling Cells Uplink and downlink decoupling cells are cells that use high bands (such as 3.5 GHz) for downlink and low bands (such as 1.8 GHz/700 MHz) for uplink to improve uplink coverage. Figure 3-5 illustrates an uplink and downlink decoupling cell. Figure 3-5 Uplink and downlink decoupling cell
3.1.3.5 RF Combination Cell In a LampSite scenario, RF signals from multiple pRRUs are combined in the RHUB to form an RF combination cell. That is, pRRUs connected to the same or different RHUBs are combined to serve one cell, extending cell coverage. See Figure 3-6. Figure 3-6 RF combination cell

3.1.4.2 NARFCN The NARFCN, center frequency of the cell carrier, is used to determine the center frequencydomain position of an NR DU cell. An NARFCN is classified into uplink NARFCN and downlink NARFCN. The uplink NARFCN must be configured for an SUL cell based on the network plan. It is specified by NRDUCell .UlNarfcn. For non-SUL cells, whether to configure the uplink NARFCN is based on the value of the NRDUCell .UlNarfcnConfigInd parameter. l
If NRDUCell.UlNarfcnConfigInd is set to CONFIG, configure the uplink NARFCN and downlink NARFCN by respectively specifying the NRDUCell.UlNarfcn and NRDUCell. DlNarfcn parameters based on the network plan.

If NRDUCell.UlNarfcnConfigInd is set to NOT_CONFIG , calculate the uplink NARFCN and downlink NARFCN based on the start and end frequencies of the cell. The calculation procedure is as follows: a.
Determine the downlink center frequency of a cell based on the downlink start frequency and downlink bandwidth of the cell. Cell's downlink center frequency (DLCELL REF) = Cell downlink start frequency (MHz) + Cell downlink bandwidth (MHz)/2
b.
Determine the uplink center frequency of a cell based on the uplink start frequency and uplink bandwidth of the cell. Cell's uplink center frequency (ULCELLREF) = Cell uplink start frequency (MHz) + Cell uplink bandwidth (MHz)/2
c.
Calculate the downlink and uplink center NARFCNs of the cell based on the cell downlink center frequency (DLCELL REF) and the cell uplink center frequency (ULCELLREF), respectively. Cell's downlink center NARFCN (NREF-DLCELL) = Int{(DLCELLREF - FREF-Offs )/ ΔFGlobal + NREF-Offs } Cell's uplink center NARFCN (NREF-ULCELL) = Int{(ULCELLREF - FREF-Offs )/ ΔFGlobal + NREF-Offs } Table 3-2 Requirements for available NARFCNs

3.1.4.3 SSB Frequency-Domain Position In an NR system, an SSB comprises a primary synchronization signal (PSS), secondary synchronization signal (SSS), and PBCH. Each SSB provides 240 consecutive subcarriers. A UE searches for cells based on received PSS and SSS signals and obtains necessary information from the received broadcast system messages. Then, the UE selects the most appropriate cell to camp on using the received information. The SSB frequency-domain position indicates the SSB center frequency position of a cell. It is specified by the NRDUCell . SsbDescMethod and NRDUCell. SsbFreqPos parameters. The SSB frequency-domain position is not configured for SUL cells, but must be configured for TDD cells. When the SSB frequency-domain position is configured, NRDUCell. SsbDescMethod is only set to SSB_DESC_TYPE_NARFCN . NRDUCell. SsbFreqPos specifies the NARFCN corresponding to the SSB center frequency. Table 3-4 lists the NRDUCell. SsbFreqPos settings. Table 3-4 SSB frequency-domain position configurations
