name: CRB
full_form: Common Resource Block
context: switching in between the two resources, where implies that the resources are configured in the same slot, and implies that the resources are configured within two adjacent slots. The bandwidth and initial common resource block (CRB) index of a CSI-RS resource within a BWP, as defined in Clause 7.4.1.5 of [4, TS 38.211], are determined based on the higher layer parameters nrofRBs and startingRB, respectively, within the CSI-FrequencyOccupation IE configured by the higher layer parameter freqBand within the CSI-RS-ResourceMapping IE. Both nrofRBs and startingRB are configured as integer multiples of 4 RBs, and the reference point for startingRB is CRB 0 on the common resource block grid. If the UE shall assume that the initial CRB index of the CSI-RS resource is , otherwise . If , the UE shall assume that the bandwidth of the CSI-RS resource is , otherwise . In all cases, the UE shall expect that .
description: Common Resource Block (CRB) is a parameter used to determine the bandwidth and initial common resource block index of a CSI-RS resource within a BWP. It is defined in Clause 7.4.1.5 of [4, TS 38.211] and is configured as an integer multiple of 4 RBs.
explanation: The text explicitly states that CRB is a parameter used to configure the bandwidth and initial common resource block index of a CSI-RS resource.
