When a fullband-enabled terminal is providing narrowband telephony, the requirements in clause 5, ‘narrowband telephony transmission performance’ shall apply. When a fullband-enabled terminal is providing wideband telephony, the requirements in clause 6, ‘Wideband telephony transmission performance’ shall apply. When a fullband-enabled terminal is providing super-wideband telephony, the requirements in clause 7, ‘Super-wideband telephony transmission performance’ shall apply.

8.11 Delay
8.11.0 UE delay definition
8.11.0.1 Acoustic interfaces
For MTSI-based speech with LTE, NR or WLAN access, the UE delays in the send and receive directions are defined for acoustic interfaces as:
– The UE delay in the send (uplink) direction is the delay between the first acoustic event at the MRP to the last bit of the corresponding speech frame at the UE antenna
– The UE delay in the receive (downlink) direction is the delay between the first bit of a speech frame at the UE antenna and the first acoustic event at the DRP corresponding to that speech frame
NOTE: In order to harmonize UMTS and LTE delay definitions, the reference points for UMTS UE delay have been changed in Rel-12. Prior to Rel-12, the UE reference points for UMTS were implicitly defined by the compensation factors declared by system simulator vendors, i.e. half of the air interface delay was attributed to the UE, and the last acoustic event at DRP was used for the receive measurement instead of the first.
Considering 10ms for half of the transmission time in each direction of a UMTS call, a speech frame size of 20ms, a codec look-ahead of 5ms, and a difference between the first and the last acoustic event of 20 ms, the previous reference points took into account a UE implementation independent delay of 2x10ms + 25 ms + 20 ms = 65 ms. The same UE delay remains in the new definition above, which attributes the full air interface delay to the UE but uses the first acoustic event at the DRP, instead of the last (2x20ms + 25 ms + 0 ms = 65 ms). Hence, the UMTS requirements with these new reference points remain the same.
8.11.0.2 Electrical interfaces
The UE delays in the send and receive directions are defined for electrical interfaces as:
– The UE delay in the send (uplink) direction is the delay between the first electrical event at the input of the electrical interface (analogue or wired digital connection) or first bit of a speech frame at the UE antenna of the wireless digital interface (wireless digital connection) to the last bit of the corresponding speech frame at the UE antenna
– The UE delay in the receive (downlink) direction is the delay between the first bit of a speech frame at the UE antenna and the first electrical event at the output of the electrical interface (analogue or wired digital connection) or first bit of a speech frame at the UE antenna of the wireless digital interface (wireless digital connection) corresponding to that speech frame.
8.11.1 Handset UE
It is in general desirable to minimize UE delays to ensure low enough end-to-end delays and hence a good conversational experience, guidance is found in ITU-T Recommendation G.114.
For MTSI-based speech-only with LTE, NR or WLAN access in error and jitter free conditions and EVS speech codec operation, the sum of the UE delays in sending and receiving directions (TS + TR) should be ≤ 157ms. If this performance objective cannot be met, the sum of the UE delays in sending and receiving directions (TS + TR) shall in any case be ≤ 197ms.
For MTSI-based speech-only with LTE, NR or WLAN access in conditions with simulated packet arrival time variations and packet loss and EVS speech codec operation, the sum of the UE delays in sending and receiving directions (TS + TR) shall be less than or equal to the delay requirements in Table 33a1, while meeting the speech quality targets defined.
NOTE: The UE delay requirements for MTSI-based speech-only with LTE, NR or WLAN access are derived from:
– A codec algorithmic delay of 32ms including speech frame buffering and encoder lookahead.
– An air interface transmission time of 1ms on receive and 1ms on the send direction.
– A budget allowance for a jitter buffer depth of 40ms for error and jitter free conditions and test conditions 0 and 1 of Table 33a1, and 80ms for test condition 2 of Table 33a1.
– A budget allowance for vendor specific implementation of 83ms corresponding to the performance objective and 123ms corresponding to the required maximum UE send and receive delay..

NOTE 1: The delay profiles for test condition 1 and 2 are theoretically constructed to simulate a semi-persistent scheduling transmission scheme with DRX enabled and target BLER in sending and receiving directions of 10%, with +/- 3ms of EPC jitter. Delay profiles are injected at the IP layer of the test system. Delay profiles are attached electronically to document 3GPP TS 26.132 [1]. The delay profiles in test condition 1 and 2 are static delay variation conditions and do not expose the UE to packet delay variations in the full range of the packet delay budget as defined for QCI1 in 3GPP TS 23.203 [18]. A third test condition that exposes the UE to non-stationary packet delay variations experienced in live operation and packet delay variations in the full range of the packet delay budget for QCI1, and accompanied delay and speech quality requirements, is for further study. |

8.11.3 Electrical interface UE
It is in general desirable to minimize UE delays to ensure low enough end-to-end delays and hence a good conversational experience, guidance is found in ITU-T Recommendation G.114.
The delay budget BD to be considered in the performance requirements and objectives depends on the type of electrical interface UE and is given by Table 33a3.

NOTE: The delay for analogue to digital conversion (and vice versa) in the wired digital connection is considered to be part of the budget allowance for vendor specific implementation in the UE delay requirements. |
|
For MTSI-based speech-only with LTE, NR or WLAN access in error and jitter free conditions and EVS speech codec operation, the sum of the UE delays in sending and receiving directions (TS + TR) should be ≤ 157+BD ms. If this performance objective cannot be met, the sum of the UE delays in sending and receiving directions (TS + TR) shall in any case be ≤ 197+BD ms.
For MTSI-based speech-only with LTE, NR or WLAN access in conditions with simulated packet arrival time variations and packet loss and EVS speech codec operation, the sum of the UE delays in sending and receiving directions (TS + TR) shall be less than or equal to the delay requirements in Table 33a3, while meeting the speech quality targets defined.

– An air interface transmission time of 1ms on receive and 1ms on the send direction.
– A budget allowance for a jitter buffer depth of 40ms for error and jitter free conditions and test conditions 0 and 1 of Table 33a4, and 80ms for test condition 2 of Table 33a4.
– A budget allowance for vendor specific implementation of 83ms corresponding to the performance objective and 123ms corresponding to the required maximum UE send and receive delay.

8.13 Clock accuracy
For MTSI-based speech-only with LTE, NR or WLAN access, the clock skew in send direction between the device under test and the reference client should be less than 50 PPM (in absolute value) in error-free conditions.
Compliance shall be checked by the relevant test described in TS 26.132.
8.14 Jitter buffer management behavior
For MTSI-based speech-only with LTE, NR or WLAN access, a jitter buffer is used in receiving to handle the variation in packet receiver timing (see clause 8 of TS 26.114 [17]).
If the jitter buffer management (JBM) behaviour is evaluated, the following statistics shall be reported for conditions specified in TS 26.132:
– Delay histogram (on a per sentence basis)
– Quality loss histogram (on a per sentence pair basis)
and all measured delay and quality loss values for these conditions shall be reported as a function of measurement time, together with minimum and maximum values.
The relevant test is described in 3GPP TS 26.132.
