在5G(NR)网络中对FR2的L1-RSRP测量精度要求分为:绝对精度和相对精度两方面;其中:
绝对精度
除非另有规定,本节中对基于 SSB 的 L1-RSRP 绝对精度的要求适用于为 L1-RSRP 测量配置的服务小区的所有 SSB。 表 10.1.20.1.1-1 中的精度要求在以下条件下有效:
- 满足 TS 38.101-2 [19] 第 7.3 节中定义的参考灵敏度条件。
- L1-RSRP 测量的条件根据附件 B.2.4.1 满足每个相关 SSB 的相应频段。
- 测量的信号位于由 TS 38.101-2 [19] 的第 7.3.4 节定义的 UE 的百分位 EIS 球形覆盖覆盖的方向上。
Table 10.1.20.1.1-1: SSB based L1-RSRP absolute accuracy in FR2
Accuracy | Conditions |
Normal condition | Extreme condition | SSB ês/Iot | Io Note 1 range |
|
|
| Minimum Io | Maximum Io |
dB | dB | dB | dBm / SCSSSB Note 2 | dBm/BWChannel | dBm/BWChannel |
|
|
| SCSSSB = 120kHz | SCSSSB = 240kHz |
|
|
±6.5 | ±9.5 | ≥-3 | Same value as SSB_RP in Table B.2.4.1-2, according to UE Power class, operating band and angle of arrival | N/A | -70 |
±8.5 | ±11.5 | ≥-3 | N/A | -70 | -50 |
NOTE 1: Io specified at the Reference point, and assumed to have constant EPRE across the bandwidth. NOTE 2: Values based on Refsens and EIS spherical coverage as defined in clauses 7.3.2 and 7.3.4 of TS 38.101-2 [19]. Applicable side condition selected depending on angle of arrival. NOTE 3: In the test cases, the SSB ês/Iot and related parameters may need to be adjusted to ensure ês/Iot at UE baseband is above the value defined in this table. |
相对精度
基于SSB的L1-RSRP的相对精度定义为从一个 SSB 测量的 L1-RSRP 与服务小区所有 SSB 中 L1-RSRP 的最大测量值相比。
表 10.1.20.1.2-1 中的精度要求在以下条件下有效:
- 满足 TS 38.101-2 [19] 第 7.3 节中定义的参考灵敏度条件。
- L1-RSRP 测量的条件根据附件 B.2.4.1 满足每个相关 SSB 的相应频段。
- 测量的信号位于由 TS 38.101-2 [19] 的第 7.3.4 节定义的 UE 的百分位 EIS 球形覆盖覆盖的方向上。

Accuracy | Conditions |
Normal condition | Extreme condition | SSB ês/Iot | Io Note 1 range |
|
|
| Minimum Io | Maximum Io |
dB | dB | dB | dBm / SCSSSB Note 3 | dBm/BWChannel |

±6.5 | ±9.5 | ≥-3 | Same value as SSB_RP in Table B.2.4.1-2, according to UE Power class, operating band and angle of arrival | -50 |
NOTE 1: Io specified at the Reference point, and assumed to have constant EPRE across the bandwidth. NOTE 2: The parameter SSB ês/Iot is the minimum SSB ês/Iot of the pair of SSBs to which the requirement applies. NOTE 3: Values based on Refsens and EIS spherical coverage as defined in clauses 7.3.2 and 7.3.4 of TS 38.101-2 [19]. Applicable side condition selected depending on angle of arrival. NOTE 4: In the test cases, the SSB ês/Iot and related parameters may need to be adjusted to ensure ês/Iot at UE baseband is above the value defined in this table. |
