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
