Definition

The IE DownlinkConfigCommon provides common downlink parameters of a cell.

DownlinkConfigCommon ::=        SEQUENCE {
    frequencyInfoDL                 FrequencyInfoDL                                 OPTIONAL,   -- Cond InterFreqHOAndServCellAdd
    initialDownlinkBWP              BWP-DownlinkCommon                              OPTIONAL,   -- Cond ServCellAdd
    ...,
    [[
        initialDownlinkBWP-RedCap-r17   BWP-DownlinkCommon                              OPTIONAL    -- Need R
    ]]
}

Fields (3)

FieldDescription
frequencyInfoDL
FrequencyInfoDL · OPTIONAL Cond InterFreqHOAndServCellAdd
Basic parameters of a downlink carrier and transmission thereon.
initialDownlinkBWP
BWP-DownlinkCommon · OPTIONAL Cond ServCellAdd
The initial downlink BWP configuration for a serving cell. The network configures the locationAndBandwidth so that the initial downlink BWP contains the entire CORESET#0 of this serving cell in the frequency domain.
initialDownlinkBWP-RedCap-r17
BWP-DownlinkCommon · OPTIONAL Need R
since v17.0.0
If present, (e)RedCap UEs use this DL BWP instead of initialDownlinkBWP . If absent, (e)RedCap UEs use initialDownlinkBWP provided that it does not exceed the (e)RedCap UE maximum bandwidth (see also clause 5.2.2.4.2).
