LTE PUCCH 1 资源计算

 

公式：  n_pucch_(1) (ref. 213)

 

假设 DL RB = UL RB = 50, PHICH 资源 1/6

 

Number of CCE depends on CFI。To calculate the CCE resources,

 

1) Cal. no. of REG in a subframe using CFI.

 

2) Cal. no. of REG to be used by PHICH group

 

TDD, the number of PHICH groups may vary between downlink subframes and is given by  m_i * Phich_group(213)

Uplink-downlink configuration	Subframe number
	0	1	2	3	4	5	6	7	8	9
0	2	1	-	-	-	2	1	-	-	-
1	0	1	-	-	1	0	1	-	-	1
