Detailed description

The upcoming 5G New Radio (NR) systems are expected to have significantly improved system capacity and quality of service. However, most of the gains come at the cost of complications in the user equipment (UE), which leads to increased power consumption in the UE.

In one example, in Long Term Evolution (LTE) systems, a cell-specific reference signal (CRS) may be used for idle mode UEs to track automatic gain control (AGC), radio resource management (RRM) measurements, paging reception, time tracking, and/or or frequency, etc. These operations, in NR systems, rely on the Synchronization Signal Block/PBCH (SSB). However, the periodicity of SSB (in NR) is much sparser than CRS (in LTE).

In addition, there is usually a gap between the SSB and the paging event (PO) in the time domain. In this case, the UE needs to wake up multiple times to detect SSB or PDCCH monitoring events in the PO, which is energy-consuming.

More generally, the configuration of the reference signal is one of the major contributors to power consumption for a UE in radio resource control (RRC) idle mode or RRC idle mode. Embodiments of the disclosed technology provide methods, devices, and systems for reducing power consumption of a UE in RRC idle mode, RRC idle mode, and RRC connected mode.

In some embodiments, reducing UE power consumption in RRC idle mode, RRC idle mode, and RRC connected mode can be achieved by providing other reference signals in addition to SSB. Considering at the same time resource overhead and network power efficiency, in one example, reference signals for RRC connection mode UEs are used for RRC sleep mode and RRC sleep mode UEs. In addition, these methods do not require additional transmission of a reference signal on the network side, thereby ensuring that the power efficiency of the network side is reduced only slightly.

In some embodiments, the reference signal is sent to an RRC idle mode UE, a sleep mode UE, or an RRC connected mode UE.

(a) Selection of Public Land Mobile Network (PLMN);

(b) Broadcasting system information;

(c) Cell reselection mobility;

(d) Paging for mobile recipient data initiated via 5GC; And

(c) Cell reselection mobility;

(d) Paging is initiated by NG-RAN (RAN paging);

(e) The RAN Notification Area (RNA) is administered by the NG-RAN;

(f) DRX for RAN paging configured by NG-RAN;

(g) A 5GC-NG-RAN connection (both C/U planes) is established for the UE;

(h) The UE AS context is maintained in the NG-RAN and the UE; And

(i) NG-RAN knows the RNA to which the UE belongs.

(3) Operations for RRC connection mode UE include:

(a) A 5GC-NG-RAN connection (both C/U planes) is established for the UE;

(b) The UE AS context is maintained in the NG-RAN and the UE;

(c) NG-RAN knows the cell to which the UE belongs;

(d) Unicast data transmission to/from the UE; And

In some embodiments, the segment with the first reference signal is determined by at least one of an offset, a duration, or a time domain reference point. In one example, the first reference signal is determined by an offset relative to the time domain reference point. In this example, the periodicity of the first reference signal is predetermined. For example, the periodicity of the first reference signal is determined by at least one of the following:

- Frequency of SSB package,

- DRX cycle frequency,

- Paging frame,

- Number of paging frames within a DRX cycle,

- Number of POs within a paging frame.

In one example, the offset of the first reference signal satisfies a predetermined requirement, which may include at least one of the following:

(1) The offset is greater than the third threshold.

(2) The offset is less than the fourth threshold.

In some embodiments, the first/second/third/fourth threshold is based on at least one of the following:

- Frequency of SSB package,

- DRX cycle frequency,

- Paging frame,

- Number of paging frames within a DRX cycle,

- Number of POs in a paging frame.

- Number of PDCCH monitoring events within the RO.

In some embodiment, the periodicity of the SSB burst is the periodicity of the SSB half-frame.

In some embodiments, the SSB comprises a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a physical broadcast channel (PBCH) with an associated demodulation reference signal (DM-RS) in consecutive symbols. An SSB packet contains one or more SSBs. In one example, one or more SSBs within one SSB packet are in the same half-frame. The number of SSBs or indexes of SSBs transmitted in an SSB packet may be specified by the network.

In one example, the first/second threshold is the SSB packet periodicity.

In one example, the SSB burst periodicity is 20 ms for initial access, and thus the first/second threshold can be set to 20 ms.

In one example, the first reference signal is configured to be provided in addition to the SSB. In this case, power savings would be reduced if the first reference signal had a periodicity that was no greater than the SSB periodicity, or if it was located close to the SSB.

(a) The predetermined period is a multiple of the DRX cycle or paging frame. In one example, the predetermined period is a DRX cycle or a paging frame.

An exemplary embodiment is shown in FIG. 6. As shown here, there is a first reference signal within a predetermined period.

An exemplary embodiment is shown in FIG. 7. As shown here, offset can be defined as the time interval between a time domain reference point and the first reference signal. The reference point in the time domain may represent the start or end of the RO, or the start or end of the first PDCCH monitoring event within the RO, or the beginning or end of the last PDCCH monitoring event within the RO.

One paging frame (PF) is one radio frame and may contain one or more POs or a PO starting point. A paging event (PO) is a set of PDCCH monitoring events and may consist of multiple time segments (eg, subframe or OFDM symbol) in which the paging DCI may be sent. The UE detects the RO for paging message scheduling information and/or system information update indication.

In some embodiments, the PF and PO for paging are determined by the following formula:

SFN for PF is defined as follows:

(SFN+PF_offset) mod T=(T div N)*(UE_ID mod N)

The index (i_s) indicating the PO index is determined by:

i_s=floor(UE_ID/N) mod Ns

The PO is a set of 'S' consecutive PDCCH monitoring events, where 'S' is the number of actual transmitted SSBs determined in accordance with ssb-PositionsInBurst in SIB1.

The following parameters are used to calculate PF and i_s above:

T: DRX UE cycle

N: number of complete paging frames in T

Ns: number of paging events for PF

PF_offset: offset used to determine PF

UE_ID: 5G-S-TMSI mod 1024
