The purpose of this procedure is to configure the UE to perform logging of measurement results while in RRC_IDLE and RRC_INACTIVE. The procedure applies to logged measurements capable UEs that are in RRC_CONNECTED.
The UE shall initiate the procedure upon receiving a logged measurement configuration in same or another RAT. The UE shall also initiate the procedure upon power off or upon deregistration.
The UE shall:
This procedure specifies the logging of available measurements by a UE in RRC_IDLE and RRC_INACTIVE that has a logged measurement configuration. The actual process of logging within the UE, takes place in RRC IDLE state could continue in RRC INACTIVE state or vice versa.
if InterFreqTargetInfo is configured and if the UE detected IDC problems on at least one of the frequencies included in InterFreqTargetInfo or any inter-RAT frequency during the last logging interval, or
if available, set the measResultNeighCells, in order of decreasing ranking-criterion as used for cell re-selection, to include measurements of neighbouring cell that became available during the last logging interval and according to the following:
include measurement results for at most 6 neighbouring cells on the NR serving frequency and for at most 3 cells per NR neighbouring frequency and for the NR neighbouring frequencies in accordance with the following:
The network initiates the procedure to a UE in RRC_CONNECTED when it needs (additional) UE radio access capability information. The network should retrieve UE capabilities only after AS security activation. Network does not forward UE capabilities that were retrieved before AS security activation to the CN.
include in the ue-CapabilityRAT-ContainerList a ue-CapabilityRAT-Container of the type UE-EUTRA-Capability associated with the terrestrial network and with the rat-Type set to eutra as specified in clause 18.104.22.168 of TS 36.331, according to the capabilityRequestFilter, if received;
The UE invokes the procedures in this clause if the NR or E-UTRA network requests UE capabilities for nr, eutra-nr or eutra. This procedure is invoked once per requested rat-Type (see clause 22.214.171.124 for capability enquiry by the NR network; see clause 126.96.36.199 of TS 36.331 for capability enquiry by the E-UTRA network). The UE shall ensure that the feature set IDs are consistent across feature sets, feature set combinations and band combinations in all three UE capability containers that the network queries with the same fields with the same values, i.e. UE-CapabilityRequestFilterNR, UE-CapabilityRequestFilterCommon and fields in UECapabilityEnquiry message (i.e. requestedFreqBandsNR-MRDC, requestedCapabilityNR, eutra-nr-only flag, and requestedCapabilityCommon) as defined in TS 36.331, where applicable.
The UE shall:
compile a list of "candidate band combinations" according to the filter criteria in capabilityRequestFilterCommon (if included), only consisting of bands included in frequencyBandListFilter, and prioritized in the order of frequencyBandListFilter (i.e. first include band combinations containing the first-listed band, then include remaining band combinations containing the second-listed band, and so on), where for each band in the band combination, the parameters of the band do not exceed maxBandwidthRequestedDL, maxBandwidthRequestedUL, maxCarriersRequestedDL, maxCarriersRequestedUL, ca-BandwidthClassDL-EUTRA or ca-BandwidthClassUL-EUTRA, whichever are received;
include into supportedBandCombinationList-UplinkTxSwitch as many NR-only band combinations that supported UL TX switching as possible from the list of "candidate band combinations", starting from the first entry;
include into featureSets the feature sets referenced from the "candidate feature set combinations" and may exclude the feature sets with the parameters that exceed any of maxBandwidthRequestedDL, maxBandwidthRequestedUL, maxCarriersRequestedDL or maxCarriersRequestedUL, whichever are received;
include into supportedBandCombinationList and/or supportedBandCombinationListNEDC-Only as many E-UTRA-NR band combinations as possible from the list of "candidate band combinations", starting from the first entry;
include into supportedBandCombinationList-UplinkTxSwitch as many E-UTRA-NR band combinations that supported UL TX switching as possible from the list of "candidate band combinations", starting from the first entry;
include into featureSetsEUTRA (in the UE-EUTRA-Capability) the feature sets referenced from the "candidate feature set combinations" and may exclude the feature sets with the parameters that exceed ca-BandwidthClassDL-EUTRA or ca-BandwidthClassUL-EUTRA, whichever are received;
include the received frequencyBandListFilter in the field appliedFreqBandListFilter of the requested UE capability, except if the requested rat-Type is nr and the network included the eutra-nr-only field;
