• 3GPP Spec

  • 38.214 chap 5.1.2.2.2 Downlink resource allocation type 1
  • 38.214 chap 6.1.2.2.2 Uplink resource allocation type 1
  



• (1) Calculate RIV

  Input (N_size_BWP, RB_start, L_RBs), then it will calculate the RIV
  • N_size_BWP:
    
  • RB_start:
    
  • L_RBs:
    
  Calculate




• (2) Calculate RB_start and L_RBs

  input (N_size_BWP, RIV), then it will calculate the RB_start and L_RBs
  • N_size_BWP:
    
  • RIV:
    
  Calculate

    ========================================================================
	ex: initialDLBWPlocationAndBandwidth = 1099
	input (N_size_BWP, RIV), then it will calculate the RB_start and L_RBs
	N_size_BWP: 275
	RIV: 1099
	Calculate
	=> RB_start = 0
	=> L_RBs = 273

	(N_size_BWP, RB_start, L_RBs)=(273, 0, 16) => calculate RIV= 4095
	(N_size_BWP, RB_start, L_RBs)=(273, 0, 52) => calculate RIV= 13923
	(N_size_BWP, RB_start, L_RBs)=(273, 0, 242) => calculate RIV= 9008
	(N_size_BWP, RB_start, L_RBs)=(273, 0, 261) => calculate RIV= 3821
	(N_size_BWP, RB_start, L_RBs)=(273, 0, 273) => calculate RIV= 545
	(N_size_BWP, RB_start, L_RBs)=(273, 12, 52) => calculate RIV= 13935
	(N_size_BWP, RB_start, L_RBs)=(273, 12, 54) => calculate RIV= 14481
	(N_size_BWP, RB_start, L_RBs)=(273, 12, 188) => calculate RIV= 23738
	(N_size_BWP, RB_start, L_RBs)=(273, 12, 261) => calculate RIV= 3809
