[0041] A UE and a NE, such as a base station, in a wireless communications system can communicate using time-frequency resources. In some examples, a NE may schedule communications over the one or more of the time-frequency resources via control signaling. For example, the NE may transmit signaling to the UE indicating one or more time periods during which a transmission may arrive, referred to as monitoring occasions. The NE may indicate a periodicity of the monitoring occasions, a starting time period of the monitoring occasions, an ending time period of the monitoring occasions, and / or a duration of the monitoring occasions, among other parameters defining the monitoring occasions.

[0042] In some examples, a UE may operate with different power consumption levels in multiple power consumption modes, such as in an active mode with relatively high power consumption and an idle or inactive mode with a relatively low power consumption. A UE in a low power mode (e.g., the idle and / or inactive mode) may operate using reduced transmission and / or reception capabilities (e.g., due to reduced transmit power, energy efficient radio transceivers, low power processors, etc.), may perform energy harvesting techniques to supplement battery power, may utilize sleep modes for different components of the UE, or the like. Examples of UEs that are operable in low power modes include, but are not limited to, internet of things (loT) devices, wearable devices, remote sensor devices, and mobile devices. In some examples, a wireless device, for example, a UE may include multiple radios, such as a radio that operates using a relatively low power consumption level, referred to as a low power radio, and a radio that operates at a relatively high power consumption level, referred to as a main radio. Further, a low power radio may be responsible for waking a main radio from a sleep mode, such as in response to different events such as a Low-Power Wake-Up Signal (LP-WUS) transmitted by a NE to a UE.

[0043] In some scenarios power saving techniques can include PDCCH skipping applicable for longer sleep duration of a main radio of a UE, such as where PDCCH skipping for 10ms allows a UE to enter light sleep state for 10ms. Further, search space switching can be applied with and without PDCCH skipping which can be applicable for a shorter duration than PDCCH skipping and allow a UE to microsleep. A UE, for instance, can be configured to monitor a search space where ina first slot the UE monitors for PDCCH and in remaining slots the UE enters microsleep such as due to data inactivity. However, configuring power-related behavior of a UE as part of PDCCH monitoring presents a number of challenges in the context of interoperability of a main radio and a low power radio of a UE in different connected mode DRX states.

[0044] Accordingly, aspects of the disclosure are directed to configuring the operation of PDCCH of a UE within an on-duration of connected mode DRX using LP-WUS signaling. For instance, a low power radio can be configured to monitor LP-WUS from NEs both outside of an active time of connected mode DRX as well as within an active time of connected mode DRX, and to wake a main radio in response to detected LP-WUS. Thus, energy conservation in wireless communications systems can be enhanced while mitigating effects on device performance such as by reducing signal latency.

[0045] Aspects of the present disclosure are described in the context of a wireless communications system.

[0046] Figure 1 illustrates an example of a wireless communications system 100 in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more NE 102, one or more UE 104, and a core network (CN) 106. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE network or an LTE- Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a NR network, such as a 5G network, a 5G-Advanced (5G-A) network, or a 5G ultrawideband (5G-UWB) network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20. The wireless communications system 100 may support radio access technologies beyond 5G, for example, 6G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA), frequency division multiple access (FDMA), or code division multiple access (CDMA), etc.

[0047] The one or more NE 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the NE 102 described herein may be orinclude or may be referred to as a network node, a base station, a network element, a network function, a network entity, a radio access network (RAN), a NodeB, an eNodeB (eNB), a nextgeneration NodeB (gNB), or other suitable terminology. An NE 102 and a UE 104 may communicate via a communication link, which may be a wireless or wired connection. For example, an NE 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface.

[0048] An NE 102 may provide a geographic coverage area for which the NE 102 may support services for one or more UEs 104 within the geographic coverage area. For example, an NE 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc.) according to one or multiple radio access technologies. In some implementations, an NE 102 may be moveable, for example, a satellite associated with a non-terrestrial network (NTN). In some implementations, different geographic coverage areas associated with the same or different radio access technologies may overlap, but the different geographic coverage areas may be associated with different NE 102.

[0049] The one or more UEs 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a remote unit, a mobile device, a wireless device, a remote device, a subscriber device, a transmitter device, a receiver device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an Internet-of-Things (loT) device, an Internet-of- Everything (loE) device, or machine-type communication (MTC) device, among other examples.

[0050] A UE 104 may be able to support wireless communication directly with other UEs 104 over a communication link. For example, a UE 104 may support wireless communication directly with another UE 104 over 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, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.

[0051] An NE 102 may support communications with the CN 106, or with another NE 102, or both. For example, an NE 102 may interface with other NE 102 or the CN 106 through one or morebackhaul links (e.g., SI, N2, N6, or other network interface). In some implementations, the NE 102 may communicate with each other directly. In some other implementations, the NE 102 may communicate with each other indirectly (e.g., via the CN 106). In some implementations, one or more NE 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC). An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as a radio heads, smart radio heads, or transmission-reception points (TRPs).

[0052] The CN 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The CN 106 may be an evolved packet core (EPC), or a 5G core (5GC), which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management functions (AMF)) and a user plane entity that routes packets or interconnects 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 entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc.) for the one or more UEs 104 served by the one or more NE 102 associated with the CN 106.

[0053] The CN 106 may communicate with a packet data network over one or more backhaul links (e.g., via an SI, N2, N6, or other network interface). The packet data network may include an application server. In some implementations, one or more UEs 104 may communicate with the application server. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the CN 106 via an NE 102. The CN 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server using the established session (e.g., the established PDU session). The PDU session may be an example of a logical connection between the UE 104 and the CN 106 (e.g., one or more network functions of the CN 106).

[0054] In the wireless communications system 100, the NEs 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers)) to perform various operations (e.g., wireless communications). In some implementations, the NEs 102 and the UEs 104 may support different resource structures. For example, the NEs 102 and the UEs 104 maysupport different frame structures. In some implementations, such as in 4G, the NEs 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the NEs 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures). The NEs 102 and the UEs 104 may support various frame structures based on one or more numerologies.

[0055] One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., / r=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., / r=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., / r=l) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., / r=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., / r=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., / r=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.

[0056] A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames). Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.

[0057] Additionally or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., / r=0, jU=l , / r=2, / r=3, / r=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot may include a number (e.g., quantity) of symbols (e.g.,Orthogonal Frequency Division Multiplexing (OFDM) symbols). In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing), a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., / r=0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.

[0058] In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations 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, the NEs 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the NEs 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data). In some implementations, FR2 may be used by the NEs 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.

[0059] FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies). For example, FR1 may be associated with a first numerology (e.g., / r=0), which includes 15 kHz subcarrier spacing; a second numerology (e.g., / r=l), which includes 30 kHz subcarrier spacing; and a third numerology (e.g., / r=2), which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies). For example, FR2 may be associated with a third numerology (e.g., / r=2), which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., / r=3), which includes 120 kHz subcarrier spacing.

[0060] According to implementations, one or more of the NEs 102 and the UEs 104 are operable to implement various aspects of the techniques described with reference to the present disclosure. For example, a UE 104 receives, from a NE 102, LP-WUS configuration at a first radioof the UE 104 (e.g., a low power radio) indicating one or more LP-WUS monitoring occasions for connected mode DRX operation outside of an active time of the connected mode DRX operation and within the active time of the connected mode DRX operation of a second radio of the UE 104, e.g., a main radio. The UE 104 monitors, by the first radio of the UE 104 and based at least in part on the LP-WUS configuration, for LP-WUS during the one or more LP-WUS monitoring occasions. Further, the UE 104 controls, based at least in part on one or more LP-WUS received during the one or more LP-WUS monitoring occasions, PDCCH behavior of the second radio of the UE 104 during the active time of the connected mode DRX operation.

[0061] Figure 2 illustrates an example of a LP-WUR system 200. The system 200 includes a UE 104 with a main radio 202 and a LP-WUR 204. A NE 102 (e.g., gNB) can transmit NR signal to the main radio 202 and LP-WUS to the LP-WUR 204. In response to the LP-WUS the LP-WUR 204 can wake the main radio 202.

[0062] For waveform generation: Flat spectrum in frequency domain provides robustness against frequency selective fading compared to concentrated energy in frequency domain; For ON- OFF keying (OOK)-4, sequence before Discrete Fourier Transform (DFT) / LS with variation in phase via such as Zadoff-Chu (ZC), M-sequence or Quadrature Amplitude Modulation (QAM) sequence can achieve more flattened spectrum; and Knowledge of sequence(s) used in LP-WUS waveform generation may improve performance for at least a receiver with I / Q branches.

[0063] In scenarios for waveform-option-3, harmonized design can accommodate OOK- l / OOK-4 and OFDM waveform, e.g., specified overlayed OFDM sequences over OOK symbol. For Radio Resource Control (RRC) IDLE / INACTIVE, in addition to existing Primary Synchronization Signal (PSS) / Secondary Synchronization Signal (SSS), Low Power Synchronization Signal (EPSS) (e.g., OOK-1 and / or OOK-4 waveform with / without overlayed OFDM sequences with potential further down selection in WI phase) for LP-WUR that cannot receive existing PSS / SSS can be supported for synchronization and / or Radio Resource Management (RRM) for serving cell.

[0064] PDCCH monitoring adaptation and / or PDCCH skipping can be implemented which can be applicable for longer sleep duration, where PDCCH skipping for 10ms allows UE to enter light sleep state for 10ms. Further, search space switching with and without PDCCH skipping can be implemented which can be applicable for shorter duration allowing UE to microsleep. For instance,a UE can be configured to monitor a search space where a first slot the UE monitors for PDCCH and in a remaining 3 slots the UE enters microsleep due to data inactivity.

[0065] Figure 3 illustrates example scenarios 300 for PDCCH monitoring adaptation enhancements for UE power saving in connected mode. The scenarios 300 include a scenario 302 for reduced PDCCH monitoring by PDCCH skipping, and a scenario 304 for reduced PDCCH monitoring by Search Space Set Group (SSSG) Switching. The scenarios 300 illustrate sections 306 where PDCCH monitoring occurs and sections 308 where PDCCH monitoring does not occur.

[0066] The present disclosure presents solutions where operation of PDCCH may be specified within the on-duration of connected mode DRX via LP-WUS signaling.

[0067] Figure 4 illustrates a scenario 400 in accordance with aspects of the present disclosure. The scenario 400, for instance, illustrates LP-WUS monitoring during connected mode DRX active time when a PDCCH skipping duration is activated for a main radio. The scenario 400 includes operation of different radios of a UE 104 including a main radio 402 and a LP-WUR 404. Operation of the main radio 402 includes a connected mode DRX (C_DRX) active time and a PDCCH skipping duration configured by a NE 102. Further, operation of the LP-WUR 404 includes an LP- WUS block 406 where the LP-WUR 404 monitors for LP-WUS outside of the connected mode DRX active time of the main radio 402, and a LP-WUS block 408 where the LP-WUR 404 monitors for LP-WUS within the connected mode DRX active time of the main radio 402 and during the PDCCH skipping duration of the main radio 402.

[0068] Different activation options are presented as part of the scenario 400 including an activation option 410 where the NE 102 transmits an activation command via LP-WUS to the LP- WUR 404 outside of the connected mode DRX active time of the main radio 402, and an activation option 412 where the NE 102 transmits an activation command to the LP-WUR 404 within the connected mode DRX active time of the main radio 402. At 414 the LP-WUR 404 can wake the main radio 402 in a next connected mode DRX on-duration and / or active time period.

[0069] In implementations LP-WUS can be monitored outside of the active time of connected mode DRX, and the following presents some options in such scenarios where a LP-WUS may indicate:

[0070] Option 1-1: Wake up the main radio and indicate the monitoring occasions for the DCI format 2_6 - when LP-WUS and DCI with Cyclic Redundancy Check (CRC) scrambled by PS- Radio Network Temporary Identifier (RNTI) (DCP) (DCI format 2_6) are configured to be monitored, along with the indication of search space id and / or CORESET identifier to monitor the DCI format 2_6 and / or symbols within the slots to monitor PDCCH. In another implementation, the LP-WUS adapts the monitoring occasions of DCI format 2_6 monitoring outside the active time of next C_DRX cycle. In another implementation, single LP-WUS indicates the DCI format 2_6 monitoring occasions outside the active time for plurality of next DRX cycles, and such indication from single LP-WUS indicating the DCI format 2_6 monitoring occasions may be in consecutive next DRX cycles or provides a bitmap of next DRX cycles to monitor DCI format 2_6 outside active time.

[0071] Option 1-2: Wake up the main radio and indicate the C_DRX on-duration starting time slot offset and / or on-duration period in the next C_DRX and / or extension of the on-duration period by x time slots from the configured on-duration period in the next C_DRX cycle. In another implementation, wake up the main radio and activate the second DRX on-duration corresponding to the secondary DRX cycle. A single LP-WUS may be mapped to primary and / or secondary DRX cycles or separate LP-WUS occasions may be mapped to each primary and secondary DRX cycles. Alternatively or additionally the wake up of next primary and / or secondary DRX cycles may be indicated separately in different LP-WUS occasions or wake up of next primary and / or secondary DRX cycles in the same LP-WUS occasion.

[0072] Option 1-3: Wake up the main radio and indicate the SCell dormancy indication within the active time of C_DRX.

[0073] Option 1-4: Wake up the main radio and indicate the search space group index to monitor when the C_DRX on-duration starts in the next C_DRX cycle.

[0074] Option 1-5: Wake up the main radio to indicate the BWP id of the active serving cells (Pcell and / or Scells) to monitor within the start of the active time of the C_DRX.

[0075] Option 1-6: Wake up the main radio and indicate the PDCCH monitoring adaptation or PDCCH skipping duration activation including the starting time slot, duration, etc., when the C_DRX on-duration starts in the next C_DRX cycle.

[0076] Option 1-7: Wake up the main radio and indicate to a UE to enable reference signal transmission and / or reception of the environment and / or object for sensing, spatial beam information to be used for the sensing transmit beam and / or sensing receive beam when the C_DRX on-duration starts in the next C_DRX cycle. In an example, LP-WUS can provide the sensing slot starting offset and sensing duration within the on-duration or outside the C-DRX active of the UE. At least some implementations can also include combinations of the above options.

[0077] In at least some implementations, LP-WUS may be activated and / or deactivated to monitor LP-WUS within the active time of the C_DRX in a UE specific dedicated semi-static signaling, MAC-CE signaling, DCI signaling to MR, and / or using LP-WUS signaling to LP-WUR where LP-WUS may be configured by a NE to monitor in a monitoring occasion within the active time. Activation of the LP-WUS can occur in various ways, such as activated / deactivated explicitly, based on entry / exit conditions determined according to a rule, and / or combinations thereof. The EPSS measurement from LP-WUR may be transmitted to the NE when requested explicitly, periodically, and / or as part of the UE assistance information to assist the NE to determine the received signal strength of LP-WUS to activate it. LP-WUS may be activated and / or deactivated according to a rule such as where the PDCCH skipping duration for a main radio is activated within the active time and the LP-WUR measures signal quality above configured threshold, and / or MR measurement of SSB / CSI-RS above a configured threshold. The LP-WUS may be activated to perform RRM measurement within the active time and / or when the PDCCH skipping duration is activated for MR during the active time, such that RRM measurement during such time duration can be offloaded to LP-WUR to allow main radio sleep mode for power saving.

[0078] The LP-WUS could be activated to monitor LP-WUS within the active time of the C_DRX, by sending an activation / deactivation command outside the active time of the C_DRX. This could be based on the measurement performed outside the active time of the C_DRX such as SSB measurement / CSI measurement and CSI reporting performed by UE. The activation / deactivation command maybe transmitted by LP-WUS monitored outside the active time or DCI WUS format 2_6 monitored outside the active time.

[0079] In at least some implementations LP-WUS may be activated by DCI and / or by a MAC CE transmitted to the main radio within the active time of the C_DRX such as based on a CSI measurement report. In such scenarios the LP-WUS may be activated to be monitored by LP-WURwhen a main radio is not monitoring PDCCH and activating the one or more monitoring occasions of LPWUR within the PDDCH skipping duration and the LP-WUS may indicate at least one or more of the following options:

[0080] Option 2- 1 : PDCCH monitoring can be resumed and monitoring occasions and search space group index to monitor can be indicated within the PDCCH skipping duration by an indication sent via LP-WUS. UE may resume PDCCH monitoring at least Pswttch symbols after a slot where the indication sent to LPWUS slot. In implementations Pswttch symbols considers the inter-processor communication delay between a LP-WUR and a main radio as well between processing latency at LP-WUR.

[0081] Option 2-2: The search space group index and / monitoring occasions to be monitored after the PDCCH skipping duration maybe indicated to the UE using LP-WUS.

[0082] Option 2-3: At the end of the PDCCH skipping duration, LP-WUS may indicate whether to continue PDCCH skipping duration and an extended duration in milliseconds, symbols, and / or slots for which to continue the PDCCH skipping.

[0083] Option 2-4: LP-WUS may activate PDCCH skipping duration and the duration value.

[0084] Option 2-5: LP-WUS may activate the second C_DRX active time duration. In another implementation, LP-WUS monitoring within the active time of the current DRX cycle may indicate to adapt the DCI 2_6 monitoring occasions before the next DRX cycle otherwise signal the presence or absence of DCI 2_6 before the next DRX cycle. In another implementation, LP-WUS monitoring within the active time of the current DRX cycle may indicate wakeup of the next DRX cycle.

[0085] Option 2-6: LP-WUS may activate the UE main radio to enable reference signal transmission and / or reception to be used for sensing and corresponding spatial beam information to be used for the sensing transmit beam and / or sensing receive beam. Implementations can also include combinations of the above options.

[0086] At least some implementations may support a plurality of LP-WUS formats and each LP-WUS format may have different payload. Lurther, when DCP is configured together with the LP-WUS, the RNTI of DCI format 2_6 may be used to determine the resource for the LP-WUS outside the active time of C_DRX. There may be a mapping between the LP-WUS resourceoccasion and the RNTI of DCI format 2_6. Further, a NE can configure and activate LP-WUS monitoring occasions for a group of UEs according to the group RNTIs. In some implementations, binary Golay spreading sequences having two phases and the sequence length may spread the LP- WUS payload modulated with the binary modulation, e.g., OOK, FSK etc., which can be suitable to multiplex plurality of LPWUS signals. Since the correlation properties of the Golay sequences are high, a plurality of LP-WUS signals may be multiplexed in the same time and / or frequency occasion but with different orthogonal spreading sequence to assist a LP-WUR to distinguish the LP-WUS from a plurality of signals without causing collision. The spreading sequence can be semi- statically configured to each of the LP-WUR and / or provided to a group of LP-WUR according to the group RNTI.
