DL-PPW-PreConfig (DL-PPW-PreConfig-r17)
DL-PPW-PreConfig-r17 is an RRC information element of 3GPP TS 38.331 (38331), the 5G NR Radio Resource Control (RRC) protocol.
Definition
The IE DL-PPW-PreConfig provides configuration for a measurement window where a UE is expected to measure the DL PRS, if it is inside the active DL BWP and with the same numerology as the active DL BWP. Based upon the indication received in the configuration, the UE identifies whether the DL PRS priority is higher than that of the other DL signals or channels and accordingly determines, for example, the UE is expected to measure the DL PRS and is not expected to receive other DL signals and channels.

| Field | Description |
|---|---|
| dl-PPW-ID-r17 DL-PPW-ID-r17 | Indicates the pre-configured ID for DL-PRS processing window configuration. |
| dl-PPW-PeriodicityAndStartSlot-r17 DL-PPW-PeriodicityAndStartSlot-r17 since v17.3.0 | Indicates the periodicity in slots and the offset of the starting slot with respect to SFN #0 slot #0 of the serving cell where the DL-PRS processing window is configured. |
| length-r17 INTEGER (1..160) | Indicates the length of DL-PRS processing window in slots. Value 1 indicates length of one slot, value 2 indicates length of two slots and so on. |
| type-r17 ENUMERATED {type1A, type1B, type2} · OPTIONAL Cond MultiType | Indicates the DL-PRS processing window type as specified in TS 38.214 [19]. |
| priority-r17 ENUMERATED {st1, st2, st3} · OPTIONAL Cond MultiState | Indicates the priority between PDCCH/PDSCH/CSI-RS and PRS as specified in TS 38.214 [19]. |
