[38.101][NR UE Spec] NR intra-band CA (contiguous CA and non-contiguous CA)

1. Intra-band contiguous CA

1.1 Aggregated channel BW of intra-band contiguous CA

1.2 RB allocation types in intra-band contiguous CA

1. Contiguous RB allocation

Definition: "An RB allocation is contiguous if L_CRB1 = 0 or L_CRB2 = 0 or (L_CRB1 ≠ 0 and L_CRB2 ≠ 0 and RB_Start1 + L_CRB1 = N_RB1 and RB_Start2 = 0), where RB_Start1, L_CRB1, and N_RB1 are for CC1, RB_Start2, L_CRB2, and N_RB2 are for CC2, CC1 is the component carrier with lower frequency. "

• Contiguous Inner RB allocation

• Contiguous Outer RB allocation
  “A contiguous allocation that is not an Inner contiguous allocation is an Outer contiguous allocation.”

2. non-contiguous RB allocation

Definition: "Non-Contiguous RB allocation is defined as RB_Start1 + L_CRB1 < N_RB1, or RB_Start2 > 0, when both uplink CCs are activated and allocated with RB(s), where RB_Start1, L_CRB1, and N_RB1 are for CC1, RB_Start2, L_CRB2, and N_RB2 are for CC2, CC1 is the component carrier with lower frequency. "

• Inner RB allocation (of non-contiguous RB allocation in intra-band contiguous CA)
  

• Outer 1 RB allocation (of non-contiguous RB allocation in intra-band contiguous CA)
  

• Outer 2 RB allocation (of non-contiguous RB allocation in intra-band contiguous CA)
  “In contiguous CA, a non-contiguous allocation is an Outer 2 allocation if it is neither a non-contiguous Inner allocation nor an Outer 1 allocation.”

1.3 MPR in intra-band contiguous CA

1. MPR in contiguous RB allocation

2. MPR in non-contiguous RB allocation

2. Intra-band non-contiguous CA

2.1 sub-block BW

2.2 RB allocation types

NA

2.3 MPR

"For intra-band non-contiguous CA, the allowed Maximum Power Reduction (MPR) for the maximum output power is specified into 2 types: MPR to meet -30dBm/MHz and -13dBm/MHz. "
