AI Technical Summary
Existing communication networks face challenges in optimizing measurement intervals for radio resource management, leading to inefficient power consumption and latency in user equipment (UE) operations, particularly in idle or inactive states.
The UE employs a wake-up radio (WUR) to perform low-power measurements using Low-Power Synchronization Signals (LP-SS) and Synchronization Signal Blocks (SSB), dynamically adjusting measurement periodicity based on configuration information and network settings to balance energy consumption and synchronization accuracy.
This approach reduces power consumption and latency by ensuring timely synchronization and efficient resource management, allowing the UE to quickly transition to active states for data processing while minimizing unnecessary wake-ups.

[0021] FIG. 1 illustrates a network environment 100 in accordance with some embodiments. The network environment 100 may include a UE 104 communicatively coupled with a base station 108 of a radio access network (RAN) 110. The UE 104 and the base station 108 may communicate over air interfaces compatible with 3GPP TSs, such as those that defme a Fifth Generation (5G) new radio (NR) system, a Sixth Generation (6G) system, or a later system. The base station 108 may provide user plane and control plane protocol terminations toward the UE 104.
[0022] The network environment 100 may further include a core network 112. For example, the core network 112 may comprise a Fifth Generation core network (5GC) , a Sixth Generation core network (6GC) , or a later generation core network. The core network 112 may be coupled to the base station 108 via a fiber optic or wireless backhaul. The core network 112 may provide functions for the UE 104 via the base station 108. These functions may include managing subscriber profile information, subscriber location, authentication of services, or switching functions for voice and data sessions.
[0023] The network environment 100 may further include a data network 120. Data network 120 may include a system of interconnected nodes that facilitate data transmission between UE 104 and various application servers and other service providers. The base station 108 and the core network 112 may route application data between the UE 104 and external data network 120 or application servers. These application servers host web applications, cloud storage, and multimedia streaming services, which communicate with the UE 104 via standardized protocols and interfaces defined by 3GPP, ensuring secure and efficient data exchange.
[0024] The UE 104 may include a radio resource control (RRC) state machine that performs operations related to various RRC procedures, including, for example, paging, RRC connection establishment, RRC connection reconfiguration, and RRC connection release. The RRC state machine may be implemented by protocol processing circuitry; for example, processor circuitry 404 of Figure 4 (e.g., baseband processor 404A, which may access communication protocol stack 436) .
[0025] The RRC state machine may transition the UE 104 into one of a number of RRC states (or “modes” ) , including, for example, a connected state (RRC connected) , an inactive state (RRC inactive) , and an idle state (RRC idle) . The UE 104 may start in RRC idle when it first camps on an NR cell, which may be after the UE 104 is switched on or after an inter-system cell reselection from a Long Term Evolution (LTE) cell. To engage in active communications, the RRC state machine may transition the UE 104 from RRC idle to RRC connected by performing an RRC setup procedure to establish a logical connection, for example, an RRC connection, with a base station. In RRC connected, the UE 104 may be configured with at least one signaling radio bearer (SRB) for signaling (for example, control messages) with the network 102; and one or more data radio bearers (DRBs) for data transmission. When the UE 104 is less actively engaged in network communications, the RRC state machine may transition the UE 104 from RRC connected to RRC inactive using an RRC release procedure. The RRC inactive state may allow the UE 104 to reduce power consumption as compared to RRC connected but will still allow the UE 104 to quickly transition back to RRC connected to transfer application data or signaling messages.
[0026] Network 102 may transmit paging messages in order to reach UEs that are in RRC idle or RRC inactive states. The UE 104 may include a main radio 122 and a wake-up radio (WUR) 124 (also referred to as a wake-up receiver or a low-power WUR (LP-WUR) ) . The main radio 122 may include radio frequency (RF) and modulator / demodulator components configured to perform primary receive and transmit operations in the course of communicating with the network device 104. Some of these receive / transmit operations are discussed in more detail with respect to UE 400 of FIG. 4. The WUR 124 may be a relatively low-complexity receiver that is designed to specifically detect a wake-up signal (WUS, also referred to as a low-power WUS (LP-WUS) ) transmitted by the RAN 110 (e.g., the base station 108) .
[0027] When not engaged in communications (e.g., receiving signals from or transmitting signals to the RAN 110) , the main radio 122 may transition to a reduced-power state, and the UE 104 may activate the WUR 124. The WUR 124 may monitor for the WUS in respective wake-up occasions. Upon detecting the WUS, the WUR 124 may provide a trigger to wake up the main radio 122 (e.g., transition the main radio 122 to a higher power state) . The primary component radio 112 may then power up to receive paging or other messages from the RAN 110, and the WUR 124 may power down. The WUR 124 may provide significant power savings for the UE 104 compared with having the primary component radio 112 powering on to periodically monitor for paging messages in paging occasions (PO) , which may rarely be detected.
[0028] The main radio 122 may be in one of a plurality of measurement modes associated with a low power state. For example, in a first measurement mode, the serving cell measurements may be fully offloaded from the main radio 122 and instead performed by the WUR 124 (e.g., on the LP-SS) . The main radio 122 may still perform measurements on neighboring cells. In a second measurement mode, the main radio 122 may perform serving cell measurements with relaxed measurement parameters (e.g., a longer measurement period) compared with a high power state. In some instances, the WUR 124 may still perform serving cell measurements on the LP-SS in the second measurement mode.
[0029] The WUR 124 may further provide some radio resource management (RRM) functionality, e.g., offloaded from the main radio 122 so that the main radio 122 can stay in the low power state. For example, the serving cell of the UE 104 may transmit the LP-SS. The LP-SS may be designed to be measured by the low-complexity WUR 124. The WUR 124 may perform one or more measurements on the LP-SS. If one or more measurements indicate that the signal quality of the serving cell is poor (e.g., one or more measurements are below a threshold) , the WUR 124 may trigger the main radio 122 to wake up to perform additional RRM (e.g., perform additional measurements on the serving cell, perform measurements on one or more neighboring cells, and / or initiate a handover procedure to transition the serving cell from a source cell to a target cell) . The main radio may perform RRM measurements on a synchronization signal block (SSB) .
[0030] The WUR 124 may perform one or more measurements on the LP-SS. The UE 104 may obtain synchronization and timing references from the LP-SS measurements. The LP-SS measurements may enable the UE 104, particularly when in idle or inactive mode, to maintain accurate timing alignment with the network. The synchronization and timing alignment may improve the efficiency of the wake-up procedure. For example, the UE 104 may determine the appropriate time to activate the main radio 122 to monitor for paging or other control signals, thus reducing unnecessary wake-ups. LP-SS transmission may be configured to be infrequent and low-power. For example, LP-SS periodicity may be 80 milliseconds (ms) , 160 ms, 640 ms, 1280 ms, 2560 ms, 5120 ms, or 10240 ms.
[0031] Alternatively, or additionally, the WUR 124 may measure SSB. SSBs may provide synchronization information, such as timing and frequency references, which may be used to accurately detect a WUS and ensure that the main radio 122 wakes up at the correct time to receive data or control information. SSB measurement by WUR 124 may provide signal quality and coverage, allowing the WUR 124 to assess the quality of the received signal and make an informed decision about whether to wake up the main radio 122.
[0032] The SSB includes a primary synchronization signal (PSS) , secondary synchronization signals (SSS) , and a physical broadcast channel (PBCH) , which collectively give a comprehensive view of the cell's quality and coverage. This level of detailed information may not be obtained by measuring the LP-SS.
[0033] The SSB and LP-SS may have independent configurations. In one example, the network 102 may configure LP-SS and SSB at the UE 104. SSB and LP-SS configurations may indicate they are associated with the same carrier or frequency band. In some examples, SSB and LP-SS may be associated with different carriers or frequency bands. For example, SSB may be transmitted on frequency f1, and LP-SS may be transmitted on frequency f2.
[0034] Two parameters are important in the performance of WUR 124: measurement delay and measurement periodicity. Measurement delay may be referred to as the time gap between detecting a WUS and activating the main radio 122. The measurement delay determines whether main radio 122 can quickly transition from a sleep state to an active state to receive and process incoming control or data signals.
[0035] The WUR 124 may frequently perform measurements. For example, the WUR 124 may perform measurement to detect WUS or for synchronization and time or frequency tracking. Measurement periodicity may refer to the interval at which the WUR 124 performs measurements. The periodicity may determine how frequently WUR 124 wakes up from its low-power state to monitor for the reference signals, e.g., SSB or LP-SS.
[0036] More frequent measurements may allow WUR 124 to maintain a more accurate and up-to-date synchronization with network 102. As a result, WUR 124 can detect WUS more promptly and with greater precision, thereby reducing the time required to align the main radio 122 with the network's timing. With more frequent synchronization, main radio 122 may transition from sleep to active state more quickly and accurately.
[0037] More frequency measurements may provide WUR 124 with up-to-date timing information, reducing the uncertainty about the next WUS occasion. WUR 124 my predict and prepare for incoming signals more effectively. The reduced latency in detecting and processing WUS may translate to a shorter measurement delay.
[0038] More frequency measurement may allow for better resource management and allocation within UE 104. WUR 124 may adjust its operation dynamically based on real-time network conditions and activate main radio 122 when necessary.
[0039] The periodicity of the measurements may impact energy consumption and performance. The periodicity of the measurement may be balanced with the measurement delay. Frequent measurements with short delays may increase energy use, while infrequent measurements with longer delays may lead to missed synchronization and higher latency.
[0040] In some embodiments, candidate values for periodicity of the LP-SS or SSB measurements by WUR 124 are provided. In some instances, WUR 124 may use both LP-SS or SSB for RRM measurements. In some instances, WUR 124 may use LP-SS or SSB for RRM measurements. In some examples, SSB and LP-SS are on the same carrier or band; in others, they are on different carriers or bands.
[0041] In some embodiments, UE 104 may determine the measurement interval or measurement periodicity when SSB and LP-SS are on the same carrier or band, network 102 configures LP-SS periodicity, and the UE 104 performs SSB measurement on LR.
[0042] In some embodiments, UE 104 may determine the measurement interval or measurement periodicity when SSB and LP-SS are on the same carrier or band and network 102 configures LP-SS periodicity, and the UE 104 performs SSB measurement or LP-SS measurement on LR.
[0043] In some embodiments, UE 104 may determine the measurement interval or measurement periodicity when SSB and LP-SS are on the same carrier or band, network 102 does not configure LP-SS periodicity, and the UE 104 performs SSB measurement on LR.
[0044] In some embodiments, UE 104 may determine the measurement interval or measurement periodicity when SSB and LP-SS are on different carriers or bands, network 102 configures LP-SS periodicity, and the UE 104 performs S SB measurement on LR.
[0045] In some embodiments, UE 104 may determine the measurement interval or measurement periodicity when SSB and LP-SS are on different carriers or bands, network 102 configures LP-SS periodicity, and the UE 104 performs SSB measurement or LP-SS measurement on ER.
[0046] In some embodiments, UE 104 may determine the measurement interval or measurement periodicity when SSB and LP-SS are on different carriers or bands, network 102 does not configure LP-SS periodicity, and the UE 104 performs SSB measurement on LR.
[0047] FIG. 2 illustrates an operation flow / algorithmic structure 200 in accordance with some embodiments. The operation flow / algorithmic structure 200 is related to determining measurement interval or measurement periodicity. The operation flow / algorithmic structure 200 may be performed or implemented by a UE such as, for example, the UE 104 or UE 400; or components thereof, for example, baseband processor circuitry 404A.
[0048] The operation flow / algorithmic structure 200 may include 210, determining that an SSB is on a first carrier (or band) and an LP-SS is on a second carrier (or band) . UE 104 may determine that SSB is on a first carrier and LP-SS is on a second carrier.
[0049] In some embodiments, the first and second carriers are the same, e.g., SSB and LP-SS are transmitted on the same frequency band or the same carrier frequency. In other embodiments, the first and second carriers are different, e.g., SSB and LP-SS are transmitted on different frequency bands or different carrier frequencies.
[0050] The operation flow / algorithmic structure 200 may include, at 220, processing configuration information. The configuration information may be received from the network in, for example, system information (SI) , system information block (SIB) , or radio resource control (RRC) configurations.
[0051] The configuration information may include discontinuous reception (DRX) configurations. DRX may allow the UE 104 to periodically enter a low-power state. DRX configuration may include an indication of the DRX cycle. DRX cycle may consist of an active period (ON-duration) followed by a sleep period (OFF-duration) . The length or duration of the DRX cycle may determine how often UE 104 wakes up to check for data.
[0052] The configuration information may include an LP-SS periodicity. In some embodiments, UE 104 may determine that the configuration does not include LP-SS periodicity.
[0053] The configuration information may include LP-WUS occasion (LO) configuration. LO may refer to specific instances when UE 104 actively monitors for a WUS. In some examples, Los may be scheduled before DRX ON-duration. LO configuration may include a periodicity or monitoring cycle length that may determine the interval at which UE 104 wakes up for monitoring for WUS.
[0054] The configuration information may include LP-WUS monitor occasion (MO) configuration. MO may be the time period during which UE's WUR 124 is actively monitoring for an LP-WUS. This occasion is configured to ensure that the WUR 122 can detect the wake-up signal. MO configuration may include a monitoring cycle parameter defining the frequency with which UE 104 wakes up to monitor for LP-WUS. MO configuration may also include a duty cycle length parameter that is related to the ratio of the active monitoring period to the sleep period within the monitoring cycle.
[0055] The configuration information may include SSB configuration. SSB configuration may include an indication associated with the SSB periodicity. SSB periodicity may determine the interval at which network 102 transmits SSB.
[0056] The configuration information may include a configuration of SSB measurement timing configuration (SMTC) . SMTC configuration may include a periodicity parameter. SMTC periodicity may determine the periodicity at which UE 104 may monitor for SSB. This could be different than SSB periodicity.
[0057] The configuration information may include SSB measurement periodicity configuration for LP-WUR-based RRM. UE 104 may use LP-WUR 124 to measure SSB. Configuration may include a fallback or default configuration. In some embodiments, the default measurement periodicity may be configured (e.g., by RRC signaling) or may be defined in the 3GPP TSs.

The configuration information that serves as a basis for the measurement periodicity may be one or more of LO periodicity, LP-WUS MO, DRX cycle, SMTC, SSB periodicity, or LP-SS periodicity as described elsewhere herein.
[0059] The operation flow / algorithmic structure 200 may include determining the measurement periodicity based on the LO periodicity. For example, the measurement periodicity may be based on a value multiplied by the LO periodicity, e.g., measurement periodicity = k * LO periodicity. For example, for k=1, measurement periodicity is the LO periodicity. In some instances, the value k may be smaller than one, e.g., k< 1. In some instances, the value k may be greater than one, e.g., k>1. As used herein, the value k may also be referred to as a scaling factor.

In some embodiments, the measurement periodicity is based on a value multiplied by the SMTC, e.g., measurement periodicity = k *SMTC. For example, for k=1, measurement periodicity is the SMTC. In some instances, the value k may be greater than or equal to one, e.g., k≥1.
[0063] The operation flow / algorithmic structure 200 may include determining determine the measurement periodicity based on the SSB periodicity.

For example, for k=1, measurement periodicity is the SSB periodicity. In some instances, the value k may be greater than or equal to 1, e.g., k>=1.
[0064] The operation flow / algorithmic structure 200 may include determining the measurement periodicity based on the DRX cycle and LP-SS periodicity. In some embodiments, the measurement periodicity is based on whichever is smaller between the DRX cycle and LP-SS periodicity, e.g., measurement periodicity = min {DRX cycle, LP-SS periodicity} . In some embodiments, the measurement periodicity is based on a value (k) multiplied by whichever is smaller between the DRX cycle and LP-SS periodicity, e.g., measurement periodicity = k *min {DRX cycle, LP-SS periodicity} . For example, for k=1, measurement periodicity is the smaller of DRX cycle and LP-SS periodicity. In some instances, the value k may be smaller than one, e.g., k<1. In some instances, the value k may be greater than one, e.g., k>1.
[0065] In some embodiments, the measurement periodicity is based on the maximum (or greater value) of the DRX cycle and LP-SS periodicity, e.g., measurement periodicity =max {DRX cycle, LP-SS periodicity} . In some embodiments, the measurement periodicity is based on a value multiplied by whichever is greater between the DRX cycle and LP-SS periodicity, e.g., measurement periodicity = k *max {DRX cycle, LP-SS periodicity} . For example, for k=1, measurement periodicity is the greater value between the DRX cycle and LP-SS periodicity. In some instances, the value k may be smaller than one, e.g., k<1. In some instances, the value k may be greater than one, e.g., k>1

For example, for k==1, measurement periodicity is whichever is smaller between the LP-WUS MO periodicity and the LP-SS periodicity. In some instances, the value k may be smaller than one, e.g., k<1. In some instances, the value k may be greater than one, e.g., k>1
[0067] In some embodiments, the measurement periodicity is based on whichever is greater between the LP-WUS MO periodicity and LP-SS periodicity, e.g., measurement periodicity = max {LP-WUS MO periodicity, LP-SS periodicity} .

For example, for k==1, measurement periodicity is the greater value between the LP-WUS MO periodicity and LP-SS periodicity.
[0068] The operation flow / algorithmic structure 200 may include determining the measurement periodicity based on the DRX cycle and a fixed value. In some embodiments, the measurement periodicity is based on the whichever is smaller between the DRX cycle and the fixed value, e.g., measurement periodicity = min {DRX cycle, fixed value M} . In some embodiments, the measurement periodicity is based on a value multiplied by the minimum of the DRX cycle and the fixed value M, e.g., measurement periodicity = k *min {DRX cycle, M} . For example, for k= 1, measurement periodicity is the smaller of DRX cycle and fixed value M. In some instances, the value k may be smaller than one, e.g., k<1.
