4.2.5 Adaptivity (medium access protocol)
4.2.5.1 Applicability
The present requirement applies to all equipment within the scope of the present document.
4.2.5.2 Definition
Automatic Transmit Power Control (ATPC) and Automatic Link Adaptation (ALA), also known as Automatic Adaptive
Coding and Modulation (ACM), are adaptivity (medium access protocol) mechanisms designed to facilitate spectrum
sharing with other devices. ATPC automatically reduces transmit power when there is excess link margin such that link
performance (throughput and FER) are not impacted. ALA automatically adapts the coding and modulation to
maximize spectral efficiency, thus reducing the transmission time of a given amount of payload. Both ATPC and ALA
reduce the interference caused to other links in the band and facilitates spectrum sharing. Equipment may support either,
or both, types of adaptivity mechanisms.
ETSI
14 Draft ETSI EN 303 722 V1.2.0 (2021-12)
4.2.5.3 Limit
4.2.5.3.0 General
ATPC and/or ALA shall be implemented by the equipment and shall be active under all circumstances, except that the
transmission of control, management, and synchronization frames are permitted without the use of ATPC or ALA.
4.2.5.3.1 Automatic Transmit Power Control
For devices equipped with transmitter power control, the difference in the average output power between the highest
power setting and lowest power setting shall be greater than or equal to 3 dB for a given constant data rate and nominal
channel bandwidth.
4.2.5.3.2 Automatic Link Adaptation
For devices equipped with automatic link adaptation, the difference in the average output power between that measured
for highest data rate and that measured for the lowest data rate should be greater than or equal to 3 dB for a given
constant path loss and nominal channel bandwidth. Alternatively, the duty cycle of the transmissions measured for
highest data rate shall be reduced by 10 % compared to that measured for the lowest data rate.
4.2.5.4 Conformance
The conformance tests as defined in clause 5.2.7 shall be carried out.
4.2.6 Occupied Channel Bandwidth
4.2.6.1 Applicability
This requirement applies to all equipment within the scope of the present document.
4.2.6.2 Definition
The Occupied Channel Bandwidth is the bandwidth containing 99 % of the power of the signal.
4.2.6.3 Limit
The Occupied Channel Bandwidth shall be less than the declared nominal Channel Bandwidth for all transmissions. The
device shall support a mode of transmission with a necessary bandwidth at least 70 % of the declared nominal channel
bandwidth. In case of smart antenna systems (devices with multiple transmit chains) each of the transmit chains shall
meet this requirement.
When equipment has simultaneous transmissions in adjacent channels, these transmissions may be considered as one
signal with an actual nominal channel bandwidth of "n" times the individual nominal channel bandwidth where "n" is
the number of adjacent channels. When equipment has simultaneous transmissions in non-adjacent channels, each
power envelope shall be considered separately.
4.2.6.4 Conformance

4.2.5.2 Definition
Automatic Transmit Power Control (ATPC) and Automatic Link Adaptation (ALA), also known as Automatic Adaptive
Coding and Modulation (ACM), are adaptivity (medium access protocol) mechanisms designed to facilitate spectrum
sharing with other devices. ATPC automatically reduces transmit power when there is excess link margin such that link
performance (throughput and FER) are not impacted. ALA automatically adapts the coding and modulation to
maximize spectral efficiency, thus reducing the transmission time of a given amount of payload. Both ATPC and ALA
reduce the interference caused to other links in the band and facilitates spectrum sharing. Equipment may support either,
or both, types of adaptivity mechanisms.
ETSI
14 ETSI EN 303 722 V1.2.1 (2022-03)
4.2.5.3 Limit
4.2.5.3.0 General
ATPC and/or ALA shall be implemented by the equipment and shall be active under all circumstances, except that the
transmission of control, management, and synchronization frames are permitted without the use of ATPC or ALA.
4.2.5.3.1 Automatic Transmit Power Control
For devices equipped with transmitter power control, the difference in the average output power between the highest

4.2.4.1 Definition
Transmitter unwanted emissions in the out-of-band domain are emissions when the equipment is in transmit mode, on
frequencies immediately outside the necessary bandwidth which results from the modulation process but excluding
spurious emissions.
ETSI
13 ETSI EN 303 722 V1.2.1 (2022-03)
4.2.4.2 Limit
The transmitter unwanted emissions in the out-of-band domain shall be less than or equal to the relative limits provided
in figure 1, where the x-axis is the ratio of frequency offset from centre frequency (f - f ) to declared nominal channel
C
BandWidth (BW), or an absolute level of -30 dBm within a 1 MHz bandwidth, whichever is greater. Non-adjacent
channels shall be tested separately. Within the 57 to 71 GHz band and outside -Rd to +Rd ratio of frequency offset from
centre frequency to declared nominal bandwidth range the -30 dBr or -30 dBm in 1 MHz whichever is the greater shall
apply, where Rd = min(2,5, 1,5 + 500 MHz/BW).

4.2.4.3 Conformance
Conformance tests as defined in clause 5.2.6 shall be carried out and result compared to the limit.
4.2.5 Adaptivity (medium access protocol)
4.2.5.1 Applicability
The present requirement applies to all equipment within the scope of the present document.
4.2.5.2 Definition
Automatic Transmit Power Control (ATPC) and Automatic Link Adaptation (ALA), also known as Automatic Adaptive
Coding and Modulation (ACM), are adaptivity (medium access protocol) mechanisms designed to facilitate spectrum
sharing with other devices. ATPC automatically reduces transmit power when there is excess link margin such that link
performance (throughput and FER) are not impacted. ALA automatically adapts the coding and modulation to
maximize spectral efficiency, thus reducing the transmission time of a given amount of payload. Both ATPC and ALA
reduce the interference caused to other links in the band and facilitates spectrum sharing. Equipment may support either,
or both, types of adaptivity mechanisms.

14 ETSI EN 303 722 V1.2.1 (2022-03)
4.2.5.3 Limit
4.2.5.3.0 General
ATPC and/or ALA shall be implemented by the equipment and shall be active under all circumstances, except that the
transmission of control, management, and synchronization frames are permitted without the use of ATPC or ALA.
4.2.5.3.1 Automatic Transmit Power Control
For devices equipped with transmitter power control, the difference in the average output power between the highest
power setting and lowest power setting shall be greater than or equal to 3 dB for a given constant data rate and nominal
channel bandwidth.
4.2.5.3.2 Automatic Link Adaptation
For devices equipped with automatic link adaptation, the difference in the average output power between that measured
for highest data rate and that measured for the lowest data rate should be greater than or equal to 3 dB for a given
constant path loss and nominal channel bandwidth. Alternatively, the duty cycle of the transmissions measured for
highest data rate shall be reduced by 10 % compared to that measured for the lowest data rate.
4.2.5.4 Conformance
The conformance tests as defined in clause 5.2.7 shall be carried out.
4.2.6 Occupied Channel Bandwidth
4.2.6.1 Applicability
This requirement applies to all equipment within the scope of the present document.
4.2.6.2 Definition
The Occupied Channel Bandwidth is the bandwidth containing 99 % of the power of the signal.
4.2.6.3 Limit
The Occupied Channel Bandwidth shall be less than the declared nominal Channel Bandwidth for all transmissions. The
device shall support a mode of transmission with a necessary bandwidth at least 70 % of the declared nominal channel
bandwidth. In case of smart antenna systems (devices with multiple transmit chains) each of the transmit chains shall
meet this requirement.
When equipment has simultaneous transmissions in adjacent channels, these transmissions may be considered as one
signal with an actual nominal channel bandwidth of "n" times the individual nominal channel bandwidth where "n" is
the number of adjacent channels. When equipment has simultaneous transmissions in non-adjacent channels, each
power envelope shall be considered separately.
4.2.6.4 Conformance
Conformance tests as defined in clause 5.2.8 shall be carried out and result compared to the limit.
4.2.7 Receiver unwanted emissions in the spurious domain
4.2.7.0 Applicability
The present requirement applies to all equipment within the scope of the present document.
ETSI
15 ETSI EN 303 722 V1.2.1 (2022-03)
4.2.7.1 Definition
These are unwanted emissions in the spurious domain while the equipment is receiving a transmission.
4.2.7.2 Limit
The level of unwanted emissions in the spurious domain shall be less than or equal to t
