e9a0692dcc3bb07e43038ed0aba9cbd5 | 38.869 | 7.3.1.1 RRC_IDLE/INACTIVE mode procedures | In RRC_IDLE and RRC_INACTIVE states, UEs shall perform RRC_IDLE/INACTIVE mode procedures defined in TS 38.304 and TS 38.331, which specify how UEs shall monitor paging, keep system information up to date, receive ETWS/CMAS information, and perform RRM measurements and corresponding cell selection/re-selection to ensure... |
e9a0692dcc3bb07e43038ed0aba9cbd5 | 38.869 | 7.3.1.2 LP-WUS monitoring and wake up procedure | Paging reception in RRC_IDLE and RRC_INACTIVE is supported both with discontinuous reception (DRX), and from Rel-17 and Rel-18, respectively, with extended DRX (eDRX). LP-WUS/WUR could also be supported with or without duty-cycled operation, i.e., as 'continuous' or as 'duty-cycled'. Since the LP-WUS/WUR feature is int... |
e9a0692dcc3bb07e43038ed0aba9cbd5 | 38.869 | 7.3.1.3 LP-WUS coverage and trigger condition | According to evaluation in section 8.2, LP-WUS link performance is considerably worse than legacy physical channels (e.g., PDCCH or PUSCH), and there could be partial LP-WUS coverage in the cell. Another possible scenario is LP-WUS could also have same coverage as legacy cell, while the details depend on the signalling... |
e9a0692dcc3bb07e43038ed0aba9cbd5 | 38.869 | 7.3.1.4 Configuration | Regarding the LP-WUS configuration, both UE and gNB must have a common understanding of when LP-WUS should be applied to avoid that UEs become unreachable in the downlink, as mentioned above in 7.2.3.1.3. Both UE and gNB could apply LP-WUS if LP-WUS has been configured in the cell in SI. This would further determine th... |
e9a0692dcc3bb07e43038ed0aba9cbd5 | 38.869 | 7.3.1.5 System information update and PWS | Reception of system information (SI) broadcast and ETWS/CMAS are RRC_IDLE mode procedures which must be supported for UE with LP-WUS/WUR. When the UE initiates the acquisition of SI, for example when SI has become outdated or upon cell change, the UE anyway needs to start up the main receiver for the reception of the S... |
e9a0692dcc3bb07e43038ed0aba9cbd5 | 38.869 | 7.3.1.6 Mobility and RRM | To ensure a UE in RRC_IDLE or RRC_INACTIVE is camping on the best cell it needs to perform mobility measurements as specified in TS 38.304. RRM measurement for mobility includes serving cell measurements and neighbour cell measurements, which can be intra-frequency or inter-frequency (including inter-RAT) measurements.... |
e9a0692dcc3bb07e43038ed0aba9cbd5 | 38.869 | 7.3.2 RRC_CONNECTED mode | |
e9a0692dcc3bb07e43038ed0aba9cbd5 | 38.869 | 7.3.2.1 RRC_CONNECTED mode procedures | For legacy UE in RRC_CONNECTED state, it should keep MR monitoring PDCCH in C-DRX active time, if C-DRX is configured, also when there is nothing scheduled for the UE. As a result, the power consumption caused by unnecessary PDCCH monitoring is unavoidable. The gain for legacy UE power saving features in RRC_CONNECTED,... |
e9a0692dcc3bb07e43038ed0aba9cbd5 | 38.869 | 7.3.2.2 LP-WUS monitoring | Similar as in RRC_IDLE/INACTIVE, there are two mechanisms to monitor LP-WUS for LP-WUS in RRC_CONNECTED, i.e. 'continuous' and 'duty-cycled' mode. For 'continuous' mode, LP-WUS is monitored continuously in time, while for 'duty-cycled' mode, LP-WUS is monitored based on a defined duty cycle, which is similar as DRX mec... |
e9a0692dcc3bb07e43038ed0aba9cbd5 | 38.869 | 7.3.2.3 LP-WUS use options | As described above, in order to save UE power consumption for PDCCH monitoring and guarantee the latency, the basic design is: when MR is in a sleep state, LR will remain active to monitor LP-WUS. When LP-WUS is received by LR, it will trigger the MR to wake up to monitor PDCCH.
The use of LP-WUS in RRC_CONNECTED could... |
e9a0692dcc3bb07e43038ed0aba9cbd5 | 38.869 | 7.3.2.4 Configuration | A UE is expected to be configured with LP-WUS/WUR in RRC_CONNECTED mode, e.g. upon RRC connection establishment, i.e., either during RRC Connection Setup or RRC Connection Resumption. Therefore, UE specific LP-WUS/WUR configuration is possible in RRC_CONNECTED mode.
The time gap between the LP-WUS monitoring occasion a... |
e9a0692dcc3bb07e43038ed0aba9cbd5 | 38.869 | 7.3.2.5 LP-WUS coexistence with DCP | On one hand, LP-WUS could be configured together with Rel-16 DCP for a specific UE. However, the UE may only use one of them at any time, e.g. depend on the network configuration or link quality, etc. It should be noted that this operation is more useful for the partial LP-SS/LP-WUS coverage as described in 7.3.2.4.
