    Syntax

    info = nrPRGInfo(carrier,prgSize)

    Description

    example

    info = nrPRGInfo(carrier,prgSize) returns information related to precoding resource block group (PRG) bundling, as defined in TS 38.214 Section 5.1.2.3, for the specified carrier configuration and PRG bundle size.

    Examples

    collapse all

    Open Live Script

    Create a carrier configuration with 10 resource blocks.

    carrier = nrCarrierConfig;
carrier.NSizeGrid = 10;

    Specify a PRG bundle size of 4. Get the PRG information.

    prgSize = 4;
info = nrPRGInfo(carrier,prgSize)
    info = struct with fields:
      NPRG: 3
    PRGSet: [10x1 double]

    Input Arguments

    collapse all

    Carrier configuration parameters, specified as an nrCarrierConfig object. Only these object properties are relevant for this function.

    PRG bundle size, specified as 2, 4, or []. Specify this input as [] to indicate wideband precoding granularity.

    Output Arguments

    collapse all

    PRG information, returned as a structure with these fields.

    FieldValueDescription
    NPRG

    Positive integer

    Number of PRGs in common resource blocks 0 to NCRB – 1, inclusive. NCRB is the number of common resource blocks (CRBs) between point A and the last CRB of the carrier grid, inclusive. It is equal to carrier.NStartGrid + carrier.NSizeGrid.

    The value of NPRG depends on prgSize.

    prgSize NPRG
    2ceil(NCRB/2)
    4ceil(NCRB/4)
    []1 (wideband precoding granularity)

    PRGSet

    Numeric column vector

    		1-based PRG indices for each resource block in the carrier grid. The length of the vector is equal to the NSizeGrid property of the carrier input.

    Data Types: struct
