- the power saving design of the UE becomes very necessary, mainly because the 5G NR system supports larger bandwidth, higher throughput, and more complex services and their matching more complex processing technologies .
- the power-saving optimized design can save the power consumption of the terminal, prolong the life of the battery, and improve the user experience, so it is very important for the 5G industrialization.
- RRC_IDLE Mode In the 5G NR system, there are currently three working states of the UE: RRC_IDLE Mode, RRC_Inactive Mode and RRC_Connected Mode. Only the UE in RRC_Connected Mode is allowed to detect the related Physical Downlink Control Channel (PDCCH), for example, the PDCCH scrambled by the Cell Radio Network Temporary Identity (C-RNTI). Since the power consumption of an NR terminal in RRC_Connected Mode has a decisive influence on the system power consumption, NR Rel-16 standardizes the UE power saving in the connected state.
- PDCCH Physical Downlink Control Channel
- C-RNTI Cell Radio Network Temporary Identity
- the UE in the connected state needs to continuously monitor the downlink control channel PDCCH (such as C-RNTI scrambling) to learn the information sent on the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH).
- PDCCH Physical Downlink Shared Channel
- the packet-based data flow is usually bursty, with data transmission for a period of time, but no data transmission for a long period of time next, and continuous monitoring of the PDCCH will inevitably lead to rapid power consumption of the UE. Therefore, when there is no data transmission, the power consumption can be reduced by stopping the reception of the PDCCH (the blind detection of the PDCCH will be stopped at this time). Therefore, the design of 3GPP is to achieve the purpose of power saving through the discontinuous reception (Discontinuous Reception, DRX) mechanism.
- DRX discontinuous Reception
- Figure 1 is a schematic diagram of the principle of discontinuous reception.
- the UE monitors the PDCCH only in the duration (On duration/DRX ON), and in the non-duration (Opportunity for DRX), that is, the DRX off time During this time, the UE does not monitor the PDCCH to reduce power consumption, that is, the UE enters the sleep mode.
- NR Rel-16 introduces group common PDCCH as an energy-saving signal before the above DRX ON.
- the PDCCH is transmitted in DRX OFF and scrambled with Power Saving Radio Network Temporary Identity (PS-RNTI) to save power consumption.
- PS-RNTI Power Saving Radio Network Temporary Identity Only when the energy-saving signal carries the UE wake-up indication, the UE will wake up the receiver in the following DRX cycle, otherwise the NR Rel-16 UE will continue to sleep.
- the base station For UEs in RRC_IDLE/RRC_Inactive Mode, the base station does not know which base station the UE resides on. For UEs in TA(tracking area)/RNA(RAN-based Notification Area), the base station or core network will trigger a paging signal to wake the UE to enter RRC_Connected Mode to receive data, or to receive SI-RNTI (System information-RNTI) scrambled system information updates.
- SI-RNTI System information-RNTI
- RRC_IDLE/RRC_Inactive Mode power saving and receiver robustness optimization are also very important.
- low-complexity NR terminals such as smart wearable devices or sensor devices, they mainly work in RRC_IDLE/RRC_Inactive Mode, and are suitable for Power saving has stricter requirements than ordinary NR terminals.
- the UE will receive paging (paging) and system information (System Information, SI).
- FIG 2 is a schematic diagram of the SSB-based Paging receiving principle.
- the terminal Before the terminal receives the paging information at the corresponding paging time (Paging Occasion, PO), it needs to receive the SSB to perform time-frequency tracking and AGC operations. If the distance between SSB and PO is far, the accuracy of time/frequency tracking (T/F tracking) will deteriorate the Paging reception performance. On the other hand, SSB is far away from PO. After receiving SSB, it cannot sleep to save power.
- Paging Occasion PO
- T/F tracking time/frequency tracking
- the power consumption increases, and in order to obtain better T/F tracking performance, considering that the PSS/SSS in the SSB only occupies 12 PRBs, in practice, multiple SSBs are often required to perform T/F tracking to improve the accuracy of fine synchronization. Further increase the time for the terminal to wake up, thereby increasing the power consumption of the terminal.
- the future evolution of the NR standard is considering the introduction of a multimedia broadcast and multicast system similar to LTE.
- the multimedia broadcast and multicast system is sent periodically in RRC-idle Mode, requiring the UE to detect and schedule DCI first, but its T/F Tracking operation
- SA stand-alone
