name: PRG
full_form: Physical Resource block Group
context: as "wideband", the UE is not expected to be scheduled with non-contiguous PRBs and the UE may assume that the same precoding is applied to the allocated resource associated with a same TCI state or a same QCL assumption. If is determined as one of the values among {2, 4}, Precoding Resource Block Group (PRGs) partitions the bandwidth part i with consecutive PRBs. Actual number of consecutive PRBs in each PRG could be one or more. The first PRG size is given by and the last PRG size given by if , and the last PRG size is if . For PDSCH scheduled by PDCCH with DCI scrambled using G-RNTI or G-CS-RNTI, is the starting PRB of the CFR and is the CFR. The UE may assume the same precoding is applied for any downlink contiguous allocation of PRBs in a PRG. For PDSCH carrying SIB1 scheduled by PDCCH with CRC scrambled by SI-RNTI, a PRG is partitioned from the lowest numbered resource block of CORESET 0 if the corresponding PDCCH is associated with CORESET 0 and Type0-PDCCH common search space
description: Physical Resource Block Group (PRG) is a parameter that partitions the bandwidth part into consecutive Physical Resource Blocks (PRBs). It determines the number of consecutive PRBs in each group, which can be one or more. The size of the first and last PRG is defined by specific formulas.
explanation: The context explicitly describes PRG as a mechanism to partition the bandwidth part into consecutive PRBs, indicating its role as a parameter that influences resource allocation and precoding in the network.
