User equipment radio wake-up due to discontinuous transmission or discontinuous reception cycles in connection mode

Abstract

Various aspects of this disclosure relate to user equipment radio wake-up due to Connected Mode Discontinuous Reception (C-DRX) or Discontinuous Reception (DTX) cycles. The techniques discussed herein provide entry and exit conditions for the active period of a user equipment's (UE) Connected Mode Discontinuous Reception (C-DRX) cycle, aligning the activity duration associated with the UE's C-DRX cycle with the active period of the cell's Discontinuous Reception (DRX) or Discontinuous Transmission (DTX) cycle. Partial overlap between DTX / DRX and C-DRX is handled by dynamically indicating an on-duration offset to align the active duration of the cell's DTX / DRX (cell DTX / DRX active period) with the active period of the UE's C-DRX cycle (C-DRX active period).

[0042] In a wireless communication system, a UE and an NE (such as a base station) can communicate using time-frequency resources. In a variant, when there is no active communication between the UE and / or NE, the UE and / or NE can implement DTX and DRX technologies to improve energy efficiency by reducing power consumption of the UE and NE. DTX and DRX technologies include defined and / or configured inactive and active periods at the UE and / or NE. During inactive periods, the NE and / or UE may not exchange signaling (e.g., transmit or receive signaling), or may exchange limited signaling (e.g., transmission via the NE's WUS and reception via the UE's WUS), and the UE and / or NE may enter a low-power state. Furthermore, during active periods, the NE and / or UE can exchange signaling in full-power or normal-power states.

[0043] In some examples, the UE can operate at different power levels in different power modes, such as an active mode with a relatively high power level and an idle or inactive mode with a relatively low power level. A UE in a low-power mode (e.g., idle and / or inactive mode) can operate with reduced transmission and / or reception capabilities (e.g., due to reduced transmit power, energy-efficient radio transceivers, low-power processors, etc.), can perform energy harvesting techniques to replenish battery power, can utilize sleep modes for different components of the UE, and so on. Examples of UEs operable in low-power modes include, but are not limited to, Internet of Things (IoT) devices, wearable devices, remote sensor devices, and mobile devices. In some examples, a wireless device (e.g., the UE) can include multiple radios, such as a radio operating at a relatively low power level (referred to as a low-power radio) and a radio operating at a relatively high power level (referred to as a main radio).

[0044] The NE can transmit a WUS (e.g., LP-WUS or DCI WUS) to the UE's low-power radio, and the low-power radio can activate (e.g., wake up) the UE's primary radio upon receiving the WUS (e.g., in response to, based on the WUS). In some examples, the WUS can trigger the activation of the primary radio for communicating with the NE, such as sending data to or receiving data from the NE. An NE employing any of the various technologies can also be referred to as a Network Energy Saving (NES) NE or an NES-providing cell.

[0045] As described herein, various entry and exit conditions for using WUS are defined for an NES cell that is configured and activated for one or both of the cell DTX or DRX (DTX / DRX) of an idle mode UE. The UE's monitoring of WUS behavior (e.g., DCI format 2_6 (UE DCI WUS) or LP-WUS) can occur during inactive periods associated with the UE's C-DRX (e.g., outside or during the active period of the C-DRX). There can also be partial overlap between the active periods associated with the cell's DTX / DRX and the active periods of the UE's C-DRX cycle. This can result in situations where the active periods associated with the UE's C-DRX cycle are outside the active periods associated with the cell's DTX / DRX.

[0046] The techniques discussed in this paper provide entry and exit conditions for the activity period of a UE's C-DRX cycle, aligning the activity duration associated with the UE's C-DRX cycle with the activity period (and associated activity duration) of the cell's DRX or DTX cycle. These techniques address partial overlap between cell DTX / DRX and C-DRX by dynamically indicating the on-duration offset, without changing the total on-duration or activity period, without changing the cycle, without shifting the on-duration offset and on-duration / activity period, or without shifting the cycle, etc., thereby aligning the activity duration of the cell DTX / DRX (cell DTX / DRX activity period) with the activity period of the UE's C-DRX cycle (C-DRX activity period).

[0047] The techniques discussed in this paper prevent the UE's C-DRX cycle from being active outside the activity duration associated with the cell's DTX / DRX, thus reducing power consumption in the UE. This power reduction is due to the low-power radio being used to receive WUS, and the primary radio being used to communicate with the NE during the activity duration associated with the cell's DTX / DRX. When the UE is not communicating with the NE, the UE's C-DRX cycle will be inactive, allowing the primary radio to be in a low-power mode (e.g., idle and / or inactive mode) outside the activity duration associated with the cell's DTX / DRX.

[0048] Various aspects of this disclosure are described in the context of wireless communication systems.

[0049] Figure 1An example of a wireless communication system 100 according to various aspects of this disclosure is illustrated. The wireless communication system 100 may include one or more NEs 102, one or more UEs 104, and a core network (CN) 106. The wireless communication system 100 may support various radio access technologies. In some implementations, the wireless communication system 100 may be a 4G network, such as an LTE network or an advanced LTE (LTE-A) network. In some other implementations, the radio communication system 100 may be a new radio (NR) network, such as a 5G network, an advanced 5G (5G-A) network, or a 5G ultra-wideband (5G-UWB) network. In other implementations, the wireless communication system 100 may be a combination of 4G and 5G networks, or other suitable radio access technologies, including IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20. The wireless communication system 100 may support radio access technologies other than 5G, such as 6G. In addition, the wireless communication system 100 can support technologies such as time division multiplexing (TDMA), frequency division multiplexing (FDMA), or code division multiplexing (CDMA).

[0050] One or more NEs 102 may be distributed across a geographical area to form a wireless communication system 100. One or more NEs among the NEs 102 described herein may be, include, or may be referred to as network nodes, base stations, network elements, network functions, network entities, radio access networks (RAN), NodeBs, eNodeBs (eNBs), next-generation NodeBs (gNBs), or other suitable terms. NEs 102 and UEs 104 may communicate via a communication link 110, which may be a wireless or wired connection. For example, NEs 102 and UEs 104 may perform wireless communication (e.g., receiving signaling, sending signaling) via a Uu interface.

[0051] NE 102 can provide a geographic coverage area for which it can support services for one or more UE 104s within that geographic coverage area. For example, NE 102 and UE 104 can support wireless communication of signals associated with services (e.g., voice, video, packet data, messaging, broadcasting, etc.) based on one or more radio access technologies. In some implementations, NE 102 can be mobile, for example, a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas associated with the same or different radio access technologies can overlap, but different geographic coverage areas can be associated with different NE 102s.

[0052] One or more UEs 104 may be distributed within a geographical area of ​​the wireless communication system 100. UE 104 may include or be referred to as a remote unit, mobile device, wireless device, remote device, subscriber device, transmitter device, receiver device, or some other suitable term. In some implementations, UE 104 may be referred to as a unit, station, terminal, or client, among other examples. Additionally or alternatively, UE 104 may be referred to as an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a Machine Type Communication (MTC) device, among other examples.

[0053] UE 104 can also support direct wireless communication with other UE 104s via a communication link. For example, UE 104 can support direct wireless communication with another UE 104 via a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular V2X deployments, the communication link may be referred to as a sidelink. For example, UE 104 can support direct wireless communication with another UE 104 via a PC5 interface.

[0054] NE 102 may support communication with CN 106, or with another NE 102, or both. For example, NE 102 may interface with other NE 102 or CN 106 via one or more backhaul links (e.g., S1, N2, N6, or another network interface). In some other implementations, NE 102 may communicate directly with each other. In some other implementations, NE 102 may communicate indirectly with each other (e.g., via CN 106). In some implementations, one or more NE 102 may include sub-components, such as access network entities, which may be an example of an access node controller (ANC). The ANC may communicate with one or more UE 104s via one or more other access network transport entities, which may be referred to as radio heads, smart radio heads, or transmit-receive points (TRPs).

[0055] CN 106 can support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. CN 106 can be an evolved packet core (EPC) or a 5G core (5GC), which may include: control plane entities that manage access and mobility (e.g., a mobility management entity (MME), access and mobility management functions (AMF)); and user plane entities that route packets or interconnections to external networks (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). In some implementations, the control plane entities may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signaling bearers, etc.) for one or more UEs 104 served by one or more NEs 102 associated with CN 106.

[0056] CN 106 can communicate with a packet data network via one or more backhaul links (e.g., via S1, N2, N6, or other network interfaces). The packet data network may include an application server. In some implementations, one or more UEs 104 can communicate with the application server. UE 104 can establish a session with CN 106 via NE 102 (e.g., a Protocol Data Unit (PDU) session, etc.). CN 106 can use the established session (e.g., an established PDU session) to route traffic (e.g., control information, data, etc.) between UE 104 and the application server. A PDU session can be an example of a logical connection between UE 104 and CN 106 (e.g., one or more network functions of CN 106).

[0057] In the wireless communication system 100, NE 102 and UE 104 can use the resources of the wireless communication system 100 (e.g., time resources (e.g., symbols, time slots, subframes, frames, etc.) or frequency resources (e.g., subcarriers, carriers)) to perform various operations (e.g., wireless communication). In some implementations, NE 102 and UE 104 can support different resource structures. For example, NE 102 and UE 104 can support different frame structures. In some implementations, such as in 4G, NE 102 and UE 104 can support a single frame structure. In some other implementations, such as in 5G and other suitable radio access technologies, NE 102 and UE 104 can support various frame structures (i.e., multiple frame structures). NE 102 and UE 104 can support various frame structures based on one or more digital technologies.

[0058] One or more digital technologies may be supported in the wireless communication system 100, and the digital technologies may include subcarrier spacing and cyclic prefix. The first digital technology (e.g., μ=0) can be associated with the first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first digital technique (e.g., ...) associated with the first subcarrier spacing (e.g., 15 kHz) is... μ =0) can utilize one time slot per subframe. Second digital technologies (e.g., μ =1) can be associated with the second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. The third digital technology (e.g., μ =2) can be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth digital technology (e.g., μ =3) can be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth digital technology (e.g., μ =4) can be associated with the fifth subcarrier spacing (e.g., 240 kHz) and the normal cyclic prefix.

[0059] The time intervals of resources (e.g., communication resources) can be organized according to frames (also called radio frames). Each frame can have a duration, for example, 10 milliseconds (ms). In some implementations, each frame can include multiple subframes. For example, each frame can include 10 subframes, and each subframe can have a duration, for example, 1 ms. In some implementations, each frame can have the same duration. In some implementations, each subframe of a frame can have the same duration.

[0060] Alternatively or concurrently, the time intervals of resources (e.g., communication resources) can be organized according to time slots. For example, a subframe may include a certain number (e.g., quantity) of time slots. The number of time slots in each subframe may also depend on one or more digital technologies supported in the wireless communication system 100. For example, a first digital technology, a second digital technology, a third digital technology, a fourth digital technology, and a fifth digital technology (i.e., ...) associated with corresponding subcarrier intervals of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz. μ =0、 μ =1、 μ =2、 μ =3、 μ=4) One time slot per subframe, two time slots per subframe, four time slots per subframe, eight time slots per subframe, and 16 time slots per subframe can be used, respectively. Each time slot can include a certain number (e.g., quantity) of symbols (e.g., OFDM symbols). In some implementations, the number (e.g., quantity) of time slots in a subframe can depend on the digital technique. For a normal cyclic prefix, a time slot can include 14 symbols. For an extended cyclic prefix (e.g., for a 60 kHz subcarrier spacing), a time slot can include 12 symbols. The relationship between the number of symbols per time slot, the number of time slots per subframe, and the number of time slots per frame for both normal and extended cyclic prefixes can depend on the digital technique. It should be understood that for the first digital technique (e.g., quantity) associated with the first subcarrier spacing (e.g., 15 kHz), μ The reference of =0 can be used interchangeably between subframes and time slots.

[0061] In the wireless communication system 100, the electromagnetic (EM) spectrum can be divided into various categories, frequency bands, frequency channels, etc., based on frequency or wavelength. For example, the wireless communication system 100 can support one or more operating frequency bands, such as frequency range names FR1 (410 MHz - 7.125 GHz), FR2 (24.25 GHz - 52.6 GHz), FR3 (7.125 GHz - 24.25 GHz), FR4 (52.6 GHz - 114.25 GHz), FR4a or FR4-1 (52.6 GHz - 71 GHz), and FR5 (114.25 GHz - 300 GHz). In some implementations, network entity 102 and UE 104 can perform wireless communication on one or more operating frequency bands. In some implementations, FR1 can be used by network entity 102 and UE 104, as well as other devices or apparatuses, for cellular communication services (e.g., control information, data). In some implementations, FR2 can be used by network entity 102 and UE 104, as well as other devices or apparatuses, for short-range, high-data-rate capabilities.

[0062] FR1 can be associated with one or more digital technologies (e.g., at least three digital technologies). For example, FR1 can be associated with the following: a first digital technology (e.g., μ =0), which includes a 15 kHz subcarrier spacing; second digital technology (e.g., μ =1), which includes a 30 kHz subcarrier spacing; third digital technology (e.g., μ =2), which includes a subcarrier spacing of 60 kHz. FR2 can be associated with one or more digital technologies (e.g., at least two digital technologies). For example, FR2 can be associated with a third digital technology (e.g., μ=2), which includes a 60 kHz subcarrier spacing; fourth digital technology (e.g., μ =3), which includes a subcarrier spacing of 120 kHz.

[0063] In some cases, a cell can refer to a radio access node that communicates with or includes a base station. A cell can have a coverage area, which is a geographical area where the cell can provide radio connectivity to devices within it. Different cells can operate on defined frequencies or frequency bands (called subcarriers). In some examples, UE 104 can establish a radio connection with a cell, and therefore that cell can be referred to as the serving cell of UE 104.

[0064] In some examples, the wireless communication system 100 may include one or more wireless devices (e.g., UE 104) that can be configured to operate in multiple power consumption modes. For example, when in a low-power mode (including idle and / or inactive modes), UE 104 may operate with reduced processing, power, and / or storage capabilities. In some examples, the wireless device may perform energy harvesting techniques to collect and store energy from received signals to replenish battery power, may use sleep modes for different components of the wireless device (e.g., transmitter, receiver, processing components, etc.), and so on. Examples of wireless devices that can operate in different power consumption modes include, but are not limited to: power-sensitive and / or small-sized devices, such as industrial sensors, controllers, wearable extended reality (XR) devices (e.g., smart glasses), and mobile devices.

[0065] UE 104 includes at least one master radio. The master radio includes: a receiver for receiving signals in the EM spectrum, a processor (also called a master processor or master baseband processor) for taking various actions based on these received signals, and optionally a transmitter for transmitting signals in the EM spectrum. In one or more implementations, UE 104 includes different radios for different RATs, such as one radio for 5G and one radio for 6G. The master radio can be placed in a low-power mode, in which the master radio consumes very little or no power. When in low-power mode, the master radio can also be referred to as sleeping or being off. Switching the master radio to a higher-power mode is also referred to as waking up or turning on the master radio.

[0066] UE 104 also includes a low-power radio, which may also be referred to as a low-power wake-up radio (LP-WUR). The low-power radio includes a receiver that receives signals in the EM spectrum, a processor (also known as a low-power processor) that takes various actions based on these received signals, and an optional transmitter that transmits signals in the EM spectrum. When woken up or turned on, the low-power radio consumes less power than the UE's main radio.

[0067] In some examples, the UE 104, which has multiple radios (including a main radio and a low-power radio), can operate in multiple power consumption modes, which will refer to Figure 2 A more detailed description follows. In some examples, the primary radio of UE 104 may operate at a different (e.g., higher) power level than the low-power radio. Therefore, when UE 104 is idle or inactive, UE 104 may configure the primary radio to operate in a sleep state. When the primary radio is in a sleep state, UE 104 may use the low-power radio to monitor for signaling that triggers activation of the primary radio (e.g., receiving and / or transmitting signaling that the low-power radio cannot transmit or receive). For example, NE 102 may send a WUS to the low-power radio to instruct UE 104 to wake up or activate the primary radio to transmit or receive signaling.

[0068] UE 104 and NE 102 can implement discontinuous periods, such as for DTX and DRX, to improve energy efficiency by reducing power consumption of UE 104 and NE 102 when there is no active communication. Discontinuous periods include inactive and active time periods defined and / or configured at UE 104 and / or NE 102. Inactive time periods may follow active time periods or vice versa, and inactive and active time periods can occur according to a period. This period-based DTX and DRX is also known as connected-mode DRX (or C-DRX). NE 102 can define the duration of inactive and active time periods as the same or different values. For DTX and DRX at NE 102 (e.g., cell DTX and DRX), NE 102 may not send or receive signaling during inactive time periods (except for WUS), and NE 102 may enter a low-power state. Example low-power states of NE 102 and / or UE 104 include idle mode and / or inactive mode, in which NE 102 and / or UE 104 reduce power consumption by reducing the amount of transmissions or receptions, deactivating one or more components of NE 102 and / or UE 104 (e.g., radio, processor, etc.). Similarly, during active periods, NE can transmit or receive signaling in full-power or normal-power states. In normal-power states, NE 102 and / or UE 104 can be used to transmit and / or receive signaling (e.g., without reducing the amount of transmissions or receptions), some or all components at NE 102 and / or UE 104 (e.g., radio, processor, etc.), etc., can be activated.

[0069] To reduce signaling overhead and power consumption at NE 102 and one or more UEs 104 communicating with NE 102, NE 102 can configure one or more monitoring periods during which UE 104 performs low-power radio monitoring of WUS. For example, NE 102 can explicitly configure monitoring periods in control signaling. Explicit indications may include one or more fields indicating the start index or time of the monitoring period, the end index or time of the monitoring period, the period of the monitoring period, the duration of the monitoring period, the number of monitoring periods, and / or any other parameters related to the monitoring periods used for low-power radio monitoring of WUS from NE 102. In some other examples, NE 102 can implicitly configure monitoring periods for WUS by configuring one or more mapping rules at UE 104. The mapping rules may indicate one or more of the following: a mapping between the monitoring timing at UE 104 and the downlink signal quality, a mapping between the monitoring timing and the subgroup identifier of UE 104, a mapping between the monitoring timing and the receiver type of the low-power radio of UE 104, or a mapping between the monitoring timing and signaling received by the primary radio (e.g., an early paging indicator (PEI) or paging timing).

[0070] The techniques discussed herein provide entry and exit conditions for the active period of the C-DRX cycle of UE 104, aligning the activity duration associated with the C-DRX cycle of UE 104 with the DRX cycle of the serving cell or the (as associated) active period of the DRX cycle. The techniques discussed herein dynamically indicate the on-duration offset to align the active duration of cell DTX / DRX (cell DTX / DRX active period) with the active period of the C-DRX cycle of UE 104 (C-DRX active period), without changing the total on-duration or active period, without changing the cycle, without shifting the on-duration offset and on-duration / active period, or without shifting the cycle. Therefore, although referred to as C-DRX, during the active period of the C-DRX cycle of UE 104, UE 104 can communicate with NE 102, including receiving data or control information (e.g., DRX) or sending data or information (e.g., DTX).

[0071] Figure 2 Example 200 of a low-power wake-up radio design architecture according to various aspects of this disclosure is illustrated. Example 200 illustrates a base station 202 and a UE 204. Base station 202 is, for example, Figure 1 NE 102. UE 204 is, for example, Figure 1UE 104. Base station 202 sends an LP-WUS, which is received by UE 204's LP-WUR, and can wake up UE 204's master radio (e.g., master receiver). UE 204 then uses the master radio to communicate with base station 202.

[0072] Use cases for low-power wake-up signals and receivers for NR air interfaces were considered. These use cases include low-power WUS / WUR for power-sensitive small-size devices, including IoT use cases such as industrial sensors and controllers, and wearable devices. Other use cases include, for example, XR / smart glasses, smartphones, etc.

[0073] The design of a low-power wake-up signal residing in a low-power wake-up radio is considered, which can be used to wake up the master radio. For waveform generation, the following observations are considered: a flat spectrum in the frequency domain provides robustness against frequency-selective fading compared to concentrated energy in the frequency domain; for on / off keying (OOK) 4 (OOK-4), a flatter spectrum can be achieved using a sequence prior to the Discrete Fourier Transform (DFT) or via a low-band spectrum (LS) with phase variations, such as a Zadoff-Chu (ZC), M-sequence, or Quadrature Amplitude Modulation (QAM) sequence; knowledge of one or more sequences used in LP-WUS waveform generation can improve performance for receivers with at least in-phase and quadrature (I / Q) branches; for waveform option 3, a coordinated design adapted to OOK... K-1 / OOK-4 and Orthogonal Frequency Division Multiplexing (OFDM) waveforms, such as a specified overlapping Orthogonal Frequency Division Multiplexing (OFDM) sequence on an OOK symbol; for Radio Resource Control (RRC) idle / inactive, in addition to the existing Primary Synchronization Signal (PSS) or Secondary Synchronization Signal (SSS), for synchronization and / or Radio Resource Management (RRM) of the serving cell, a low-power synchronization signal (LP-SS) is also supported for LP-WURs where the existing PSS / SSS cannot be received (e.g., one or both of OOK-1 / or OOK-4 waveforms with or without overlapping OFDM sequences, with potential further downlink options in the WI phase).

[0074] This paper discusses the cell DTX / DRX mechanism in the time domain of the UE under RRC_CONNECTED mode. To facilitate reducing NE transmission or reception activity time, auxiliary NE DTX and DRX functions (also known as cell DTX and cell DRX operations) are discussed. The UE can be configured with periodic cell DTX / DRX modes (e.g., during NE activity and inactivity periods). Cell DTX and cell DRX modes can be configured and activated individually or together; for example, two cell DTX / DRX modes can be configured per MAC entity for different serving cells. The design focus of DTX / DRX is that cell DTX in RRC can only be configured when the UE C-DRX is configured. During the inactive period of cell DTX / DRX, the UE does not receive or transmit certain channels or signals on the corresponding cell. Cell DTX / DRX can be activated or deactivated via RRC signaling in DCI format 2_9 or L1 group common signaling. DCI format 2_9 can also be used to dynamically enable or disable NES-specific conditional handover (CHO) execution conditions. The techniques discussed in this article are applicable to UEs in the RRC_CONNECTED state and do not affect random access procedures, SSB transmissions, paging, and system information broadcasts.

[0075] One problem addressed by the techniques discussed in this paper is that when cell DTX / DRX is activated during connected mode, UE monitoring of WUS behavior (e.g., DCI format 2_6 (UE DCI WUS) or LP-WUS) can occur during inactive periods associated with the UE's C-DRX (e.g., outside of the active C-DRX period or duration). It also addresses how to manage situations where there is partial overlap between the UE's cell DTX / DRX and C-DRX, and whether or not to monitor any physical channels.

[0076] Figure 3 An example flowchart 300 illustrates the entry and exit conditions of an LR according to various aspects of this disclosure. Flowchart 300 can implement various aspects of the wireless communication system 100. Flowchart 300 can be implemented by a UE and / or NE (e.g., serving cell), and they can be references. Figure 1 and Figure 2 Examples of the corresponding devices described.

[0077] At point 302, the UE's primary radio can perform the cell selection procedure. The cell selection procedure can be provided to the UE to establish a connection with the serving cell.

[0078] At 304, the UE can determine whether the low-power radio entry conditions are met. For example, entry conditions may include one or more of the following: signal strength and / or quality measurements from the serving cell meet a threshold; the serving cell's DTX and / or DRX cycle configuration or activation state; no SSB transmission and / or on-demand SSB transmission configuration or activation state; one or more capabilities of the low-power radio to perform a cell reselection process; etc. At 306, the UE can continue using the primary radio. For example, if the low-power entry conditions are not met, the UE can continue using the primary radio (e.g., the low-power radio may not be activated). At 308, the primary radio can enter a sleep state, and the low-power radio monitors the WUS and signaling for performing or including serving cell measurements. If the low-power entry conditions are met, the UE can activate the low-power radio to monitor the WUS and / or perform serving cell measurements. The UE can deactivate the primary radio by configuring it to enter a sleep state.

[0079] At point 310, the UE can determine whether the low-power radio exit conditions have been met. For example, exit conditions include one or more of the following: signal strength and / or quality measurements of signaling from the serving cell fail to meet a threshold; the serving cell's DTX and / or DRX cycle is configured or activated; no SSB transmission and / or on-demand SSB transmission is configured or activated; the low-power radio has one or more capabilities to perform a cell reselection process, etc. At point 312, the UE activates the primary radio. For example, if the exit conditions are met, the UE can activate the primary radio. At point 314, the UE can continue using the low-power radio. For example, if the exit conditions are not met, the UE can continue using the low-power radio.

[0080] In some examples, at 316, the UE can monitor the WUS using a low-power radio. The UE can monitor the WUS until the low-power radio exit condition is met and / or until the WUS is received. For example, at 318, the UE activates the primary radio. For example, if the UE receives the WUS, the UE can activate the primary radio.

[0081] In one or more implementations, one or both of the entry or exit conditions of LP-WUS are configured in the System Information Block (SIB).

[0082] In one or more implementations, the entry conditions for using LP-WUS include at least good serving cell quality, for example, serving cell quality measurements on the LR and / or serving cell quality measurements on the primary radio being better than one or more configuration thresholds in the SIB. Other conditions may also be considered.

[0083] In one or more implementations, the UE stops using LP-WUS when one or more exit conditions configured in the SIB are met. The one or more exit conditions may include at least the area outside the coverage of the LP signaling, for example, the serving cell quality measured by the LR being below a threshold configured in the SIB. Other conditions may also be considered.

[0084] In one or more implementations, serving cell quality measurements on the LR are based on LP-SS and / or synchronization signal blocks (SSB).

[0085] In one or more implementations, after being woken up by LP-WUS, consider the following scenarios: the UE monitors paging DCI / paging; if configured and supported, the UE monitors PEI (LP-WUS and PEI can be used together, e.g., sub-packets); the UE directly performs random access, and LP-WUS may include UE_ID or equivalent (e.g., depending on the capacity of the information carried by LP-WUS).

[0086] In one or more implementations, after being woken up by LP-WUS, the baseline is that the UE monitors the traditional paging opportunity (PO).

[0087] In one or more implementations, the sub-packet method for LP-WUS includes allocated core network (CN) and / or UE_ID-based sub-packets, and the LP-WUS sub-packet method is similar to the PEI sub-packet method.

[0088] In one or more implementations, the number of subgroups depends on the LP-WUS payload.

[0089] In one or more implementations, the network knows whether the UE is monitoring the low-power radio or the primary radio. In this case, this reduces Uu resource consumption because the network only sends LP-WUS when the target UE is monitoring it. Alternatively, this results in a lower false wake-up rate because other UEs monitoring LP-WUS in the same group as the target paging UE will not be woken up due to false wake-ups when LP-WUS is not sent. Alternatively, this may result in more signaling overhead because the UE notifies the network when it starts or stops monitoring using the primary radio, leading to increased Uu resource consumption or increased UE power consumption.

[0090] In one or more implementations, the network does not know whether the UE is monitoring a low-power radio or the primary radio. In this case, since the UE does not need to notify the network whether its primary radio is being monitored, there is no signaling overhead, Uu resource consumption, or UE power consumption caused by primary radio status reporting. Alternatively, this may result in higher Uu resource consumption because the network always sends LP-WUS signals, assuming the target UE is always monitoring LP-WUS, or it may result in a higher LP-WUS alarm rate (if the target UE is not monitoring LP-WUS, other UEs (monitoring the same LP-WUS as the target UE) will be woken up).

[0091] In one or more implementations, for a UE in the RRC_IDLE / RRC_INACTIVE state, the network may need to know whether the UE is monitoring LP-WUS.

[0092] In one or more implementations, during deep sleep, if RRM measurements on the LR are feasible or supported, RRM measurements on the serving cell via the master radio are relaxed (may include not being measured).

[0093] In one or more implementations, during deep sleep, if RRM measurements on the LR are feasible or supported, RRM measurements on neighboring cells via the master radio are relaxed (may include not being measured).

[0094] In one or more implementations, LP-WUS wakes the UE from deep sleep whenever there is an applicability of a signal integrity (SI) change notification, such as an Earthquake and Tsunami Warning System (ETWS) / Commercial Mobile Alert System (CMAS) message.

[0095] For NES cells configured and activated for cell DTX / DRX of idle mode UEs, various entry and exit conditions using LP-WUS can be defined. In some cases, the NE may need to wake the UE from low-power processor state to primary radio state to perform cell reselection.

[0096] Regarding the UE's monitoring of WUS behavior (e.g., DCI format 2_6 and / or LP-WUS) for an NES cell in connected mode when cell DTX / DRX is activated, the UE can monitor WUS (e.g., DCI format 2_6 (DCI-WUS) and / or LP-WUS) outside the active time of the UE's C-DRX cycle when cell DTX / DRX is activated and the cell is in an inactive period. The active time of the UE's C-DRX cycle is also referred to as the active duration associated with the UE's C-DRX cycle. The inactive or non-active time or period of the UE's C-DRX cycle is also referred to as the inactive duration associated with the UE's C-DRX. The active time of cell DTX / DRX is also referred to as the active duration associated with the cell DTX / DRX. The inactive time of cell DTX / DRX is also referred to as the inactive duration associated with the cell DTX / DRX.

[0097] In one or more implementations, when cell DTX / DRX is activated, the UE does not receive or monitor DCI format 2_6, and only receives LP-WUS outside the active time of the UE's C-DRX cycle.

[0098] In one or more implementations, entry and exit conditions for receiving LP-WUS via low-power radio (LR) are configured regarding cell DTX / DRX activation in an NES cell during connected mode.

[0099] The entry conditions for using LP-WUS can be considered if the serving cell quality of the primary radio is higher than a certain configuration threshold, and then when LP-SS is not transmitted during the inactive period of cell DTX / DRX, during the period when cell DTX / DRX is activated for serving the cell, the LR of a UE that uses LP-SS for synchronization may not enter LR mode, while a UE that does not use LP-SS for synchronization may be able to enter LR, assuming that NR SSB can be used by LR for synchronization and it is being transmitted during the inactive period of cell DTX / DRX.

[0100] Figure 4Example 400 illustrates an alignment of the activity duration associated with a UE's C-DRX cycle and the activity duration associated with a cell's DTX or DRX cycle, according to various aspects of this disclosure. Example 400 illustrates various techniques for handling partial overlap between cell DTX / DRX and C-DRX. Example 400 illustrates a timeline for cell DTX / DRX cycle 402, including an activity duration 404, followed by an inactive duration 406, and then an activity duration 408. The example also illustrates additional timelines 410, 412, and 414 for different techniques used to align the activity duration associated with a UE's C-DRX cycle and the activity duration associated with a cell's DTX or DRX cycle.

[0101] Example 400 also illustrates a timeline 410 for a UE's C-DRX cycle, where there is partial overlap between cell DTX / DRX and C-DRX. Timeline 410 includes WUS monitoring times 416 and 418, and an activity duration 420 associated with the UE's C-DRX cycle. Timeline 410 shows the UE monitoring WUS outside of the C-DRX activity time (e.g., activity duration 420), where the WUS can dynamically signal the start offset of the C-DRX on-time duration aligned with the cell DTX / DRX activity period. In this case, the C-DRX start offset configuration is moved to align with the start offset configuration of the cell DTX / DRX activity period; however, the c-DRX cycle and duration are not modified. This is illustrated as the c-DRX start offset moving from 422 to 424, such that the start of the activity duration 420 associated with the UE's c-DRX aligns with the start of the activity duration 404. As shown in the figure, the UE monitors WUS outside the cell DTX / DRX activity time, but the C-DRX activity time begins (or is within) the cell DTX / DRX activity time.

[0102] Example 400 also illustrates a timeline 412 for a C-DRX cycle for the UE. Timeline 412 includes WUS monitoring times 426 and 428, and an activity duration 430 associated with the UE's C-DRX cycle. Timeline 412 shows the UE monitoring the WUS outside the C-DRX activity time (e.g., activity duration 430), where the WUS can dynamically signal the start offset of the C-DRX on-time duration aligned with the cell DTX / DRX activity period. In this case, the C-DRX start offset configuration is moved to align with the start offset configuration of the cell DTX / DRX activity period, as well as the cycle and duration. This is illustrated as the c-DRX start offset being moved such that the start of the activity duration 430 associated with the UE's c-DRX aligns with the start of the activity duration 404. As shown, the UE monitors the WUS outside the cell DTX / DRX activity time, but the C-DRX activity period begins (or is within) the cell DTX / DRX activity time.

[0103] Example 400 also illustrates a timeline 414 for a C-DRX cycle for the UE. Timeline 414 includes WUS monitoring times 432 and 434, and an activity duration 436 associated with the UE's C-DRX cycle and an activity duration 438 associated with the next C-DRX cycle. Timeline 414 shows the UE monitoring WUS outside the C-DRX activity time, where the LP-WUS can dynamically signal monitoring opportunities for DCI format 2_6 outside the C-DRX activity time period aligned with the cell DTX / DRX activity period. Furthermore, the C-DRX start offset configuration is moved by the LP-WUS to align with the start offset configuration of the cell DTX / DRX activity period and the start offset configuration of the cycle and duration. As shown, the UE monitors WUS outside the cell DTX / DRX activity time, but the C-DRX activity time period begins (or is within) the cell DTX / DRX activity time.

[0104] Alternatively, timeline 414 illustrates the UE monitoring WUS outside the C-DRX activity period, where the WUS timing can dynamically signal monitoring timings in DCI format 2_6 outside the activity period of the first C-DRX time period (activity duration 436), which aligns with the activity period of the cell DTX / DRX activity period from the next C-DRX timing (activity duration 438). Furthermore, the C-DRX start offset configuration is moved to align with the start offset configuration of the cell DTX / DRX activity period, as well as the start offset configuration of the period and duration. As shown, the UE monitors WUS outside the cell DTX / DRX activity period, but the C-DRX activity period begins (or is within) the cell DTX / DRX activity period.

[0105] Therefore, as described herein, the behavior of the UE in monitoring DCI format 2_6 and LP-WUS for NES cells in connected mode when cell DTX / DRX is activated is described.

[0106] Alternatively or alternatively, without changing the total on-time / activity period or cycle, or without shifting the on-time offset and on-time or activity period or cycle, the partial overlap between cell DTX / DRX and C-DRX is addressed, and the on-time offset is dynamically indicated to align the cell DTX / DRX activity period and the C-DRX activity period. Alternatively or alternatively, multiple C-DRX configurations may exist, where one C-DRX configuration is associated with the primary radio, and another C-DRX configuration is associated with the LP-WUR. The C-DRX activity period of the primary radio and the cell DTX and DRX activity periods may be partially or completely aligned. In one or more implementations, when the primary radio's C-DRX is active, the LP-WUR's C-DRX enters an inactive period.

Non-transitory storage media may be any available medium that can be accessed by a general-purpose or special-purpose computer.

[0111] In some implementations, processor 502 and memory 504 coupled to processor 502 may be configured such that UE 500 performs one or more of the functions described herein (e.g., instructions stored in memory 504 are executed by processor 502). For example, according to the examples disclosed herein, processor 502 may support wireless communication at UE 500. UE 500 may be configured or operable to support components for: receiving WUS via a first radio of the UE during an inactive duration associated with a C-DRX cycle; and activating a second radio of the UE for wireless communication with a base station, at least partially based on WUS, during at least one active duration associated with one or more DTX cycles or DRX cycles of the base station, wherein the active duration associated with the UE's C-DRX cycle is aligned with at least one active duration associated with one or more DTX cycles or DRX cycles of the base station.
