Definition

The IE ZP-CSI-RS-Resource is used to configure a Zero-Power (ZP) CSI-RS resource (see TS 38.214 [19], clause 5.1.4.2). Reconfiguration of a ZP-CSI-RS-Resource between periodic or semi-persistent and aperiodic is not supported.

ZP-CSI-RS-Resource ::=              SEQUENCE {
    zp-CSI-RS-ResourceId                ZP-CSI-RS-ResourceId,
    resourceMapping                     CSI-RS-ResourceMapping,
    periodicityAndOffset                CSI-ResourcePeriodicityAndOffset                OPTIONAL, --Cond PeriodicOrSemiPersistent
    ...

FieldDescription
zp-CSI-RS-ResourceId
ZP-CSI-RS-ResourceId
since v15.1.0
ZP CSI-RS resource configuration ID (see TS 38.214 [19], clause 5.1.4.2).
resourceMapping
CSI-RS-ResourceMapping
OFDM symbol and subcarrier occupancy of the ZP-CSI-RS resource within a slot.
periodicityAndOffset
CSI-ResourcePeriodicityAndOffset · OPTIONAL Cond PeriodicOrSemiPersistent
since v15.1.0
Periodicity and slot offset for periodic/semi-persistent ZP-CSI-RS (see TS 38.214 [19], clause 5.1.4.2). Network always configures the UE with a value for this field for periodic and semi-persistent ZP-CSI-RS resource (as indicated in PDSCH-Config).
