5G網(wǎng)絡(luò)中用于CA/DC空閑模式測量FR2同頻RSRP精度對終端(UE)的要求如下:
絕對 SS-RSRP 準(zhǔn)確度
除非另有說明,本節(jié)對 SS-RSRP 絕對精度的要求適用于與 FR2 中服務(wù)小區(qū)頻率相同的小區(qū)。
表 10.1.3.1.1-1 中的精度要求在以下條件下有效:
- 滿足 TS 38.101-2 [19] 第 7.3 節(jié)中定義的參考靈敏度條件。
- 根據(jù)附件 B.2.2,針對每個相關(guān) SSB 的相應(yīng)頻段,滿足頻率內(nèi)測量的條件。
- 測量的信號位于由 TS 38.101-2 [19] 的第 7.3.4 節(jié)定義的 UE 的百分位 EIS 球形覆蓋覆蓋的方向上。
Table 10.1.3.1.1-1: SS-RSRP Intra frequency absolute accuracy in FR2
Accuracy | Conditions |
Normal condition | Extreme condition | SSB ês/Iot | Io Note 2 range |
|
|
| Minimum Io | Maximum Io |
dB | dB | dB | dBm / SCSSSB Note 1 | dBm/BWChannel | dBm/BWChannel |
|
|
| SCSSSB = 120kHz | SCSSSB = 240kHz |
|
|
±6 | ±9 | ≥-6 | Same value as SSB_RP in Table B.2.2-2, according to UE Power class, operating band and angle of arrival | N/A | -70 |
±8 | ±11 |
| N/A | -70 | -50 |
Note 1: 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 2: Io specified at the Reference point, and assumed to have constant EPRE across the bandwidth. 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. |
相對SS-RSRP準(zhǔn)確度
SS-RSRP 的相對精度定義為從一個小區(qū)測得的 SS-RSRP 與在相同頻率上從另一個小區(qū)測得的 SS-RSRP 相比,或在 FR2 中在同一小區(qū)上測得的任何兩個 SS-RSRP 水平之間。
- 滿足 TS 38.101-2 [19] 第 7.3 節(jié)中定義的參考靈敏度條件。
- 根據(jù)附件 B.2.2,針對每個相關(guān) SSB 的相應(yīng)頻段,滿足頻率內(nèi)測量的條件。
- 測量的信號位于由 TS 38.101-2 [19] 的第 7.3.4 節(jié)定義的 UE 的百分位 EIS 球形覆蓋覆蓋的方向上。

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. Note 4: The parameter SSB ês/Iot is the minimum SSB ês/Iot of the pair of cells to which the requirement applies. |
