Definition

The IE DownlinkPreemption is used to configure the UE to monitor PDCCH for the INT-RNTI (interruption).

DownlinkPreemption ::=              SEQUENCE {
    int-RNTI                            RNTI-Value,
    timeFrequencySet                    ENUMERATED {set0, set1},
    dci-PayloadSize                     INTEGER (0..maxINT-DCI-PayloadSize),
    int-ConfigurationPerServingCell     SEQUENCE (SIZE (1..maxNrofServingCells)) OF INT-ConfigurationPerServingCell,
    ...
}

Fields (4)

FieldDescription
int-RNTI
RNTI-Value
RNTI used for indication pre-emption in DL (see TS 38.213 [13], clause 10).
timeFrequencySet
ENUMERATED {set0, set1}
Set selection for DL-preemption indication (see TS 38.213 [13], clause 11.2) The set determines how the UE interprets the DL preemption DCI payload.
dci-PayloadSize
INTEGER (0..maxINT-DCI-PayloadSize)
Total length of the DCI payload scrambled with INT-RNTI (see TS 38.213 [13], clause 11.2).
int-ConfigurationPerServingCell
SEQUENCE (SIZE (1..maxNrofServingCells)) OF INT-ConfigurationPerServingCell
Indicates (per serving cell) the position of the 14 bit INT values inside the DCI payload (see TS 38.213 [13], clause 11.2).
