If both criteria are met, we believe that the UE will not stop measurement in this case. Since the network indicates option b to the UE, this means that the network expects to relax the measurement and expects the measurement result reported by the UE. Otherwise, the network will indicate option a to the UE. Therefore, if both criteria are met, the UE can choose either one, depending on the UE implementation.
  • Recommendation 2 When the network is configured with low mobility and non-edge cell standard parameters at the same time,-if the network indicates option a, when these two standards are met, the UE stops the same-frequency and inter-frequency adjacent cell measurement. -If the network indicates option b, the UE performs the corresponding loose measurement according to which conditions are met. If these two conditions are met, the UE selects one (low mobility or non-edge cell) and performs the corresponding loose measurement. In NB-IoT, the following loose delay monitoring and measurement rules are defined in TS 36.304. The time interval from the last cell reselection measurement is defined as 24 hours.
  • 5.2.4.12.0 Loose monitoring measurement rules
  • the UE can choose not to perform intra-frequency or inter-frequency measurement in the following cases Measurement:-Meet the loose monitoring criteria in section 5.2.4.12.1 during TSearchDeltaP, and-Less than 24 hours have passed since the last cell reselection measurement was performed, and-The UE is selecting or reselecting to a new cell After that, at least TSearchDeltaP same-frequency or different-frequency measurements were performed.
  • the UE In the power saving mode, if both conditions are met, and the network indicates option a, the UE will stop the same-frequency and inter-frequency neighbor cell measurement. In this case, the interval from the last cell reselection measurement should be considered. Obviously, 24 hours is not suitable for power saving terminals. This value should consider network deployment, propagation environment, UE moving direction, UE speed, UE location, etc. Too long a period configuration will affect the UE's mobility performance, and a too short period configuration will reduce the power saving gain. Generally speaking, we consider the time interval of measurement relaxation (stop measurement), because the last measurement of cell reselection was in the order of minutes.
  • Recommendation 3 Starting from the last cell reselection measurement, the time interval for measurement relaxation (measurement stop) is on the order of minutes. l RRM measurement relaxation of the inter-frequency layer with higher priority RAN4 discussed the RRM measurement with higher priority in the inter-frequency layer.
  • RRM measurement relax high-priority inter-frequency layer option 1 When Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, for higher-priority inter-frequency measurements, it is not expected to relax the current measurement delay requirements. "When Srxlev d SnonIntraSearchP or Squal d SnonIntraSearchQ, the loose measurement requirements for the high-priority frequency layer are the same as the loose measurement requirements for the peer/low-priority frequency layer.
  • Alternative 2 “In high-speed mobile scenarios, high priority Carrier measurement should not be relaxed (Scenario #2)
  • Option 3 “The measurement of higher priority carriers should not be relaxed.
  • RAN2 is discussing high-priority measurement relaxation instructions, and would like to ask RAN4 about the relaxation behavior of high-priority carriers: 1. For the situation of Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, if the relaxation criteria defined by RAN2 are met, does RAN4 envisage further relaxation than Higher_priority_search Measurement of higher priority carriers? 2.
  • the UE behavior is to measure inter-frequency layers with higher, same or lower priority layers. In the current specification, the measurement requirements for high priority, equal priority, or low priority are the same in this case.
  • the paging opportunity is indispensable and cannot be missed.
  • the UE can perform co-frequency measurement at the paging moment, which means that co-frequency measurement will not introduce additional large power consumption.
  • the UE needs to wake up during the DRX-OFF period to avoid a decrease in paging reception.
  • the measurement requirements for different frequencies scale with the number of frequencies. That is, when the number of inter-frequency layers is greater than one layer, the normalized power is not raised.
  • Recommendation 5 Reduce the number of inter-frequency layers for idle state measurement, which cannot bring energy-saving gains.
  • CA/DC is enhanced to introduce the function of reporting early measurement reports.
  • the purpose of EMR is to speed up the establishment of CA/DC when the UE enters the connected state. If the UE is in the power saving mode, it may affect the normal measurement. There are two situations that need to be discussed separately. In scenes #1 and #2, relaxation measurement should be performed. As far as we know, EMR is not an urgent function. The measurement results obtained by performing relaxation measurements on the carrier indicated by the EMR configuration can still be applied to EMR.
  • Proposal 6 In scenarios #1 and #2, the measurement results obtained from the relaxation measurement can still be applied to EMR. In scenario #3, when the UE is in the power saving mode, the UE can stop the neighbor cell measurement. However, if the UE also configures the EMR configuration in the RRC release, when the UE is ready to enter the RRC connected mode, the UE has no information about the neighbor cell measurement results. In this case, the UE may need to establish CA or DC due to traffic load. The EMR measurement is reasonable. Considering power saving, the UE can perform relaxation measurements.
  • Recommendation 7 In scenario #3, when the UE configures EMR, the UE will perform relaxation measurement. l
  • the impact of cross-slot scheduling energy-saving technology on RRM RAN1 was discussing energy-saving cross-slot scheduling at the last meeting.
  • the impact framework of BWP switching is basically as follows.
  • the minimum applicable scheduling offset indication field (if present in the DCI format) Indicates the minimum scheduling offset limit applied to the target BWP. Note: The specifications do not need to be changed.
  • BWP handover delay requirements based on DCI in RAN4 are not affected by cross-slot scheduling.
  • Recommendation 2 When the network is configured with low mobility and non-edge cell standard parameters at the same time,-if the network indicates option a, when these two standards are met, the UE stops the same-frequency and inter-frequency adjacent cell measurement. -If the network indicates option b, the UE performs the corresponding loose measurement according to which conditions are met.
