lna端口使用-多样性路径的端口安排

为了保证多元路径操作的正确性，prx和drx

端口分配需要遵循如下规则

*混音器组概念

--prx1~prx8和drx1~drx8是mlb混音器

--prx9~prx14和drx9~drx14是mhb混音器

*多样性路径端口选择规则

drx必须与prx同属一个混音器组

-例如：

*b3主路径分配给prx5，它属于mlb混音器组

•因此，必须在drx1~drx8中分配b3的多样性路径

-示例：drx3可以，drx5也可以

•在这种情况下，不允许将b3 drx分配给drx 9~drx14

-例：drx9是被禁止的

——强烈建议将drx与prx以相同的编号进行分配

-例如：

•如果b3的主路径分配给prx7，强烈建议分配b3的多样性

drx7的路径





LNA Port Usage - Port Arrangement for Diversity Path

• In order to keep diversity path operation correct, the PRX and DRX

port assignment needs to follow the rule as follows

• Mixer Group Concept

– PRX1~PRX8 and DRX1~DRX8 are MLB mixer groups

– PRX9~PRX14 and DRX9~DRX14 are MHB mixer groups

• Rule of diversity path port selection

– DRX must be in the same mixer group as PRX

- Example:

• B3 primary path is assigned to PRX5 which is belong to MLB mixer group

• Therefore, B3 diversity path must be assigned within DRX1~DRX8

- Example: DRX3 is ok, and DRX5 is also ok

• In this case, B3 DRX is not allowed to be assigned to DRX9~DRX14

- Example: DRX9 is forbidden

– It is strongly suggested to assign the DRX in the same number as PRX

- Example:

• If B3 primary path is assigned to PRX7, it is strongly suggested to assign the B3 diversity

path to DRX7

lna端口使用-ca操作

为了获得最好的ca性能并确保

函数正确，请按照

参考设计

·规则

---有7个LNA组

----波段应与参考组同一组

ca操作的设计

----例如：

-对于中国sku，b3应以lb/mb(4)分配用于ca操作

•因为根据参考设计，b3被分配给prx7或prx8

----特殊情况：

-b2在prx/drx 9~prx/drx14不支持ca操作

LNA Port Usage - CA operation

• In order to get the best CA performance and make sure that

the function is correct, please follow the band assignment of

reference design

• Rule

– There are 7 LNA groups

– The band should be assigned in the same group as the reference

design for CA operation

– Example:

- For China SKU, B3 should be assigned in LB/MB(4) for CA operation

• Because according to the reference design, B3 is assigned to PRX7 or PRX8

– Special case:

- B2 at PRX/DRX9~PRX/DRX14 does not support CA operation
