4. Definitions
The following terms are used in this document:
Active antenna system (AAS)
An antenna system where the amplitude and/or phase between antenna elements is dynamically adjusted, resulting in an antenna pattern that varies in response to short-term changes in the radio environment. An AAS may be integrated into a fixed station or base station. An antenna system used for long-term beam shaping, such as fixed electrical down tilt, is not considered an AAS.
Active antenna system (AAS) base station equipment
Base station equipment using an AAS.
Fixed subscriber equipment
Fixed equipment that provides connectivity between the user and the base station equipment. Fixed subscriber equipment is used at a fixed location. Fixed point-to-point equipment, portable, mobile, and nomadic equipment are not considered fixed subscriber equipment.
Frequency block
In the bands covered by this RSS, 1710-1780 MHz and 2110-2200 MHz, frequency blocks are portions of spectrum as defined in tables 1 and 2.
Frequency block group
A continuous frequency range of multiple frequency blocks that contains the equipment's channel bandwidth.
Non-active antenna system (non-AAS)
An antenna system that does not meet the criteria of an AAS.
Non-active antenna system (non-AAS) base station
A base station using a non-AAS.
Subscriber equipment
Equipment that provides connectivity between the user and the base station equipment. It includes but not limited to mobile, portable, nomadic and fixed subscriber equipment.
Total radiated power (TRP)
The integral of the power transmitted by an antenna (all radiating elements) in different directions over the entire radiation sphere.
5. Transmitter requirements
This section sets out the requirements applicable to radio transmitters subject to this standard.
5.1 Measurement methods
Unless otherwise specified, all measurements shall be performed in accordance with the requirements of RSS-Gen.
The equipment measurement shall be performed for all operating channel bandwidths. In addition, for the unwanted emissions, the carrier frequency shall be set at both the highest and lowest channels in which the equipment is designed to operate.
A narrower resolution bandwidth may be used, provided that the measured power is integrated over the full required measurement bandwidth (i.e. 1 MHz or 1% of the occupied bandwidth, as applicable).
5.2 Band plan
The bands 1710-1780 MHz and 2110-2180 MHz are divided into 11 paired blocks as shown in table 1. Standard Radio System Plan SRSP-513, Technical Requirements for Advanced Wireless Services in the Bands 1710-1780 MHz and 2110-2180 MHz, contains the detailed band plan.
| Block | Lower sub-band (MHz) | Upper sub-band (MHz) | Total block size (MHz) |
|---|---|---|---|
| Block A | 1710-1720 | 2110-2120 | 20 |
| Block B | 1720-1730 | 2120-2130 | 20 |
| Block C | 1730-1735 | 2130-2135 | 10 |
| Block D | 1735-1740 | 2135-2140 | 10 |
| Block E | 1740-1745 | 2140-2145 | 10 |
| Block F | 1745-1755 | 2145-2155 | 20 |
| Block G | 1755-1760 | 2155-2160 | 10 |
| Block H | 1760-1765 | 2160-2165 | 10 |
| Block I | 1765-1770 | 2165-2170 | 10 |
| Block J1 | 1770-1775 | 2170-2175 | 10 |
| Block J2 | 1775-1780 | 2175-2180 | 10 |
The band 2180-2200 MHz is divided into two downlink-only blocks, as shown in table 2. SRSP-519, Technical Requirements for the Ancillary Terrestrial Component of Mobile-Satellite Service Systems Operating in the Bands 2000-2020 MHz and 2180-2200 MHz, contains the detailed band plan. In this RSS, AWS-4 is referred to as ATC band 2180-2200 MHz.
| Block | Frequency range (MHz) | Block size (MHz) |
|---|---|---|
| Block C | 2180-2190 | 10 |
| Block D | 2190-2200 | 10 |
The blocks listed in tables 1 and 2 can be aggregated to form a larger channel.
5.3 Types of modulation
Devices may use any type of modulation technique. The type of modulation shall be documented in the test report.
5.4 Frequency stability
The frequency stability shall be sufficient to ensure that the occupied bandwidth stays within the operating frequency block or frequency block group when tested to the temperature and supply voltage variations specified in RSS-Gen.
5.5 Transmitter output power
The maximum output power of the equipment shall comply with the limits specified below. In the tables, maximum power refers to the equivalent isotropically radiated power (e.i.r.p.) or total radiated power (TRP), measured in terms of average values.
The limits in this RSS are specified for the purpose of certification and may not apply to all deployment scenarios. Consult SRSP-513 and SRSP-519 for more details on the bands 2110-2180 MHz and 2180-2200 MHz respectively.
| Equipment type | Maximum power |
|---|---|
| Fixed station and base station | 30 dBm e.i.r.p./channel bandwidth |
| Subscriber equipment | 30 dBm e.i.r.p./channel bandwidth |
| Equipment type | Maximum power |
|---|---|
| Non-AAS fixed station and base station | 65 dBm e.i.r.p./MHz |
| AAS fixed station and base station | 46 dBm TRP/MHz |
| Subscriber equipment | 30 dBm e.i.r.p./channel bandwidth |
| Equipment type | Maximum power |
|---|---|
| Non-AAS base station | 65 dBm e.i.r.p./MHz |
| AAS base station | 46 dBm TRP/MHz |
In addition, the peak to average power ratio (PAPR) of the equipment shall not exceed 13 dB for more than 0.1% of the time, using a signal that corresponds to the highest PAPR during periods of continuous transmission.
5.6 Unwanted emission limits
Unwanted emissions shall be measured in terms of average values.
For all equipment, the TRP or total conducted power (sum of conducted power across all antenna connectors) of the unwanted emissions outside the frequency block or frequency block group shall not exceed the limits shown in table 6.
| Offset from the edge of the frequency block or frequency block group | Unwanted emission limits |
|---|---|
| 1 MHz | -13 dBm/(1% of OB*) |
| >1 MHz | -13 dBm/MHz |
*OB is the occupied bandwidth.
In addition to complying with the above limits, equipment operating in the band 2180-2200 MHz may require additional filtering (see SRSP-519).
5.7 Additional requirements for subscriber equipment
Subscriber equipment other than fixed subscriber equipment shall use transmitter power control to limit power. The applicant shall include, with the application for certification, a declaration of compliance that confirms the control requirement was met and that includes a description of how the requirement was met. The declaration of compliance may be included as a separate document or attached (e.g. as an annex) to the test report.
Subscriber equipment operating in the band 1755-1780 MHz shall operate only when under the control of a base station. The applicant shall include, with the application for certification, a declaration of compliance that confirms the control requirement was met and that includes a description of how the requirement was met. The declaration of compliance may be included as a separate document or attached (e.g. as an annex) to the test report.
