TECHNIQUES FOR SENSING WAKEUP SIGNAL

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a network entity indicating one or more parameters for a wakeup signal (WUS) associated with a sensing reference signal. The UE may monitor for the WUS during one or more sensing WUS (S-WUS) monitoring occasions. The network entity may transmit the WUS based on the one or more parameters to the UE, where the UE is operating in an idle mode. The UE may communicate the sensing reference signal based on the WUS. The S-WUS may be configured as a separate signal from a standard WUS used for data communications, or a portion of a field of a WUS used for data communications may be used to indicate sensing information. For example, the S-WUS may use unused or additional bits of the WUS.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques for a sensing wakeup signal (S-WUS). For example, the described techniques provide for a user equipment (UE) to receive an S-WUS while operating in an idle state. The S-WUS may indicate for the UE to wake up to communicate (e.g., receive or transmit, or both) a sensing reference signal. A network entity may transmit control signaling to indicate a configuration for the S-WUS to the UE. The network entity may configure the UE behavior (e.g., transmission or reception of the S-WUS) when the UE detects the S-WUS. For example, the UE may be configured to monitor for a sensing reference signal or to transmit a sensing reference signal based on detecting the S-WUS. In some examples, the S-WUS may be configured as a separate signal from a wakeup signal (WUS) used for data communications, or a portion of a field of a WUS used for data communications may be used to indicate sensing wakeup information.

DETAILED DESCRIPTION

In some wireless communication systems, a user equipment (UE) and network entity may communicate using radio frequency signals. In some examples, one or more UEs and network entities may use radio frequency sensing, where radio waves, such as sensing reference signals, are reflected off devices and received by another device. in some cases, radio frequency sensing may be employed for proximity and location detection. For example, a UE may receive or transmit a sensing reference signal reflected off a target object to determine the location of the UE or the target object, or both. However, if the UE is operating in an idle mode to reduce power consumption, the UE may not be aware of occasions for the UE to receive or transmit the sensing reference signal.

Wireless communications systems described herein may support a sensing wakeup signal (S-WUS) for a UE to receive when in operating in an idle state. The S-WUS may indicate for the UE to wake up to communicate (e.g., receive or transmit, or both) a sensing reference signal. A network entity may transmit control signaling to the UE to indicate a configuration for the S-WUS. The network entity may configure the UE behavior based on detecting the S-WUS. For example, the UE may be configured to monitor for a sensing reference signal or to transmit a sensing reference signal based on detecting the S-WUS. In some examples, the S-WUS may be configured as a separate signal from a standard WUS used for data communications. For example, the network entity may configure monitoring occasions for the S-WUS, which may be periodic or semi-persistent. In some examples, the monitoring occasions for the S-WUS may be aligned with other occasions or cycles, such as synchronization signal block (SSB) occasions, a paging occasion of the UE, a discontinuous reception (DRX) cycle of the UE, or other WUSs used for data signaling. In some examples, a portion of a field of a WUS used for data signaling may be used to indicate sensing wakeup information.

Particular aspects of the subject matter described herein may be implemented to realize one or more advantages. The described techniques may support improvements in sensing procedures by decreasing signaling overhead, reducing power consumption of the UE, improving reliability, and decreasing latency, among other advantages. For example, the UE may remain in a lower power state while still being able to receive sensing reference signals for target object location detection. As such, supported techniques may include improved network operations and, in some examples, may promote network efficiencies, among other benefits.

Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, a process flow diagram, and flowcharts that relate to techniques for a S-WUS.

In some examples, a UE115may operate in a discontinuous reception (DRX) mode, where the UE115may periodically cycle between DRX on and DRX off durations of a DRX cycle. The UE115may be configured to monitor for a WUS outside a DRX on duration, and in some examples, a set of WUS monitoring occasions may be associated with each DRX cycle. A WUS may indicate whether the MAC entity of the UE115should start a timer (e.g., drx-onDurationTimer) for the next DRX cycle. The WUS may not impact other timers (e.g., bwp-inactivityTimer, datalnactivityTimer, and sCellDeactivationTimer).

In some examples, the WUS may be configured via control signaling. For example, a WUS may be transmitted via a physical downlink control channel (PDCCH) using a downlink control information (DCI) format (e.g., DCI format 2_6) with a cyclic redundancy check (CRC) scrambled by a power saving radio network temporary identifier (PS-RNTI). In some examples, the WUS may be shared by a group of UEs115and be monitored in common UE115search space sets. The WUS may be configured for a primary cell. In some examples, the WUS may indicate the dormancy behavior for secondary cell groups (e.g., a maximum of 5 groups). The WUS may be applied to sensing reference signals or radio frequency sensing procedures.

Radio frequency sensing may be implemented in a wireless communications system100. Radio frequency sensing may have dedicated frequency and time domain resources for sensing operations, as well as a dedicated network entity105. A wireless communications system may support various radio frequency sensing use cases. For example, radio frequency sensing (e.g., indicated by the parameter FS_Sensing) may be applied to joint communication or joint sensing, environmental scanning, object detection, and weather monitoring, among other applications. The wireless communications system100may support NR based sensing and collection of sensing measurement data, NR based sensing measurement data for processing, processing of sensing measurement data, processing of assisted information (e.g., location), and mechanisms to expose sensing measurement data or expose sensing results to authorized third-party applications via the core network.

In some examples, the wireless communications system100may support radio frequency sensing. Radio frequency sensing may be performed during a sensing session to determine the location of a target object. A sensing session may involve a subset of TRPs, UEs115, or both. A sensing entity, such as a network entity105or dedicated network, may determine which nodes participate in the sensing based on the capability, location, and target location of the UEs115and the TRPs.

A UE115may be triggered to participate in a sensing session depending on the location of the UE115and the location of the target object. For example, the UE115may participate in a sensing session if the target object is moving to track the position of the target object as the target object moves. In some examples, not all UEs115may participate, such as if a UE115becomes out of coverage of the target reflections. The network entity105, or the sensing entity, may dynamically adjust the set of UEs115that participate in the sensing session. Dynamic adjustment may allow the network to optimize the sensing session, energy savings, and overall over the air (OTA) radio frequency transmissions.

In some examples, the UE115may operate in an idle or inactive state or power saving mode, and the UE115may not be awake to monitor the sensing signal or transmit a sensing signal. In some other examples, the UE115may be in RRC connected mode, where the UE115monitors for the PDCCH when indicated to do so by the WUS.

Techniques described herein support an S-WUS for radio frequency sensing operations. These techniques may include power saving mode operations for the UE115and configurations for the UE to operate. The UE115may receive the S-WUS when in an idle state, and the S-WUS may indicate for the UE115to wake up to communicate (e.g., receive or transmit, or both) a sensing reference signal. A network entity105may transmit control signaling to indicate a configuration for the S-WUS to the UE115. The network entity105may configure the UE115behavior when the UE115detects the S-WUS. For example, the network entity105may configure the UE115to monitor for a sensing reference signal or to transmit a sensing reference signal based on detecting the S-WUS. In some examples, the S-WUS may be configured as a separate signal from a WUS used for data communications, or a portion of a field of a WUS used for data communications may be used to indicate sensing information. For example, the S-WUS may be indicated via unused or additional bits of the WUS.

FIG.2illustrates an example of a wireless communications system200that supports techniques for a S-WUS in accordance with one or more aspects of the present disclosure. In some examples, the wireless communications system200may implement aspects of the wireless communications system100or may be implemented by aspects of the wireless communications system100. For example, the wireless communications system200may include one or more UEs115, such as a UE115-a, a UE115-b, a UE115-c, or a UE115-d, or any combination thereof. The wireless communications system200may include a network entity105or aspects of a network entity105. For example, the wireless communications system may include a sensing entity215and one or more TRPs, such as a TRP220-a, or a TRP220-b, or both. In some examples, the sensing entity215and one or more TRPs may be examples of, or be examples of aspects of, the network entity105. The wireless communications system200may include one or more target objects, such as a target object230-aand a target object230-b.

The sensing entity215may communicate with the TRP220-avia the communication link205-aand communicate with the TRP220-bvia the communication link205-b. The TRP220-aand the TRP220-bmay communicate via the interface210. The interface210may be an example of an Xn interface, or another link. The link205-aand the link205-bmay be the same as or different than the interface210, such that the link205-aand the link205-bmay also be Xn interfaces. The TRPs220may communicate using one or more beams225, which may be transmit beams, receive beams, or both. The sensing reference signals may be transmitted or received by the beams225, and the WUS and S-WUS may be transmitted by a beam225.

The TRPs220may communicate with the UEs115via the beams225. For example, the TRP220-amay transmit a sensing reference signal using the beam225-a. The sensing reference signal may be reflected off the target object230-aand received by the UE115-a(e.g., or the UE115-b). Likewise, a sensing reference signal transmitted by the TRP220-busing the beam225-bmay be reflected off the target object230-band received by the UE115-c(e.g., or the UE115-d). In some examples, the TRP220may transmit via a direct line of sight to the UE115. In some other examples, the TRP220may transmit signaling which is reflected off the target object230and be received by the UE115.

In some examples, a target object230may move. For example, a target object230may move from the space of the target object230-ato the space of the target object230-b. As the target object230moves, a TRP220may select different beams225for transmission, or the sensing entity215may use different TRPs to transmit sensing reference signals. As the target object230moves away from some of the UEs115and closer to other UEs115, different UEs may be active in receiving the reflections of transmissions. For example, the UE115-band the UE115-amay be active during a first time period to receive reflections of transmissions, and the UE115-cand the UE115-dmay be active during a second time period. Control signaling in accordance with the WUS framework may activate the first and second time periods or devices (e.g., UEs115or TRPs220) to performing the sensing during the first and second time periods. The activation of the UEs115may include activation of transmissions of sensing reference signals, the reception of sensing reference signals, the monitoring of sensing reference signals, or a combination thereof.

The wireless communications system200may support an S-WUS, which may be transmitted to indicate for a UE115to wake up communicate (e.g., receive or transmit, or both) a sensing reference signal. For example, if the UE115is operating in an idle mode to reduce power consumption, the UE115may not be aware of occasions for the UE115to receive or transmit the sensing reference signal, and the S-WUS may wake up the UE115to do so. The TRP220may transmit control signaling to the UE115via the beam225to indicate a configuration for the S-WUS and may configure the UE behavior upon the UE115detecting the S-WUS. For example, the UE115may be configured to monitor for a sensing reference signal or to transmit a sensing reference signal based on detecting the S-WUS. The sensing reference signals may reflect off the target object230, and aid in location identification of the UE115, the target object230, or both. In some examples, the S-WUS may be configured as a separate signal from a standard WUS used for data communications, or a portion of a field of a WUS used for data signaling may be used to indicate sensing wakeup information.

The UEs115may receive a S-WUS from the TRP220transmitted via the beam225and reflected off the target object230while the UE115is in an idle or inactive mode. In some examples, the UE115may receive the S-WUS in RRC connected mode, where the UE115may only monitor for a PDCCH when notified by the WUS. The S-WUS may wake up the UE115to transmit, receive, or both, sensing reference signals. The sensing reference signals may also be received and transmitted via the beams225, and reflected off the target object230. The S-WUS may be a separate signal or indicated as part of additional bits or unused bits of the WUS.

The S-WUS may be configured as a separate signal from the WUS. The UEs115may be configured to monitor for the S-WUS, which may include monitoring for a S-WUS monitoring occasion and WUS waveform and detection threshold. The S-WUS monitoring occasion may be periodic (e.g., RRC configured) or semi-persistent (e.g., RRC configured, activated by MAC control element (MAC-CE) or DCI). In some examples, the UEs115may be dynamically configured with monitoring occasions for the S-WUS (e.g., by MAC-CE or DCI). The monitoring occasion may be aligned with other occasions or cycles (e.g., synchronization signal block (SSB), paging occasion, DRX cycle, or other WUSs).

The S-WUS waveform may be a dedicated signal that may be used for S-WUS, such as a defined DCI-based S-WUS. The configuration to monitor for the S-WUS may be specific to one or more UEs115, such as a defined and specific sensing-RNTI. The configuration may indicate behavior (e.g., receiving and transmitting behavior) of the UE115based on detecting the S-WUS. For example, the UE115behavior may include receiving behavior for the UE115to monitor one or more sensing reference signals, transmitting behavior for the UE115to transmit one or more sensing reference signals. The UE115may receive information related to sensing reference signal reception, transmission, or both by means of either RRC configuration or sensing entity protocol (e.g., similar to LTE positioning protocol (LPP)). In some examples, if the S-WUS is not detected, the default behavior of the UE115is to not receive or transmit sensing reference signals.

The configuration for the S-WUS may be two bits (e.g., additional bits of the WUS), and the interpretation of the two bits may be RRC configured or pre-defined. The S-WUS indication may be valid for UE configurations for transmission or reception of sensing reference signals between two S-WUS monitoring occasions, irrespective of the DRX on duration (e.g., the sensing reference signal may be outside of the DRX on duration). In some examples, the S-WUS indication may be valid for UE configurations for transmission or reception of sensing reference signals between two S-WUS monitoring occasions and that fully overlap with the DRX on duration. In some examples, a transmitted sensing reference signal may be intended to be received by multiple UEs, TRPs, or both. In such examples, the UE115connected DRX cycle may be UE-specific, and the sensing reference signal time domain resource allocation may not overlap with the DRX on duration of all UEs115.

The configuration of the S-WUS may include a field of two bits, as depicted in Table 1. Bit option may include 00, 01, 10, or 11. Each bit option may tell the UE115a different interpretation for the S-WUS, such as whether or not to transmit or receive sensing reference signals. For example, the 00 may indicate for the UE115to not transmit and not receive, the 01 may indicate for the UE115to transmit and not receive, the 10 may indicate to not transmit and to receive, and the 11 may indicate for the UE115to transmit and receive one or more sensing reference signals.

In some examples, the S-WUS indication may be indicated as part of the WUS, such as by the addition of bits or the use of unused bits. To indicate the S-WUS occasion using the WUS, two bits may be added to indicate the UE115behavior with respect to the sensing session. The two bits may indicate UE115behavior as described with respect to Table 1. In some other examples, such as if the UE115is configured by a content field with less than 5 secondary cells (e.g., the content field is 5 bits or less), the rest of the unused bits are configured for the sensing behavior. For example, if 1 bit is available, the bit controls the reception behavior (e.g., 0 indicates no reception, 1 indicates reception), and the UE115does not transmit. If two bits are available, both reception and transmission behaviors are specified, as further explained herein with respect to Table 1. If more than 2 bits are available, a subset of these bits may be RRC configured to indicate the sensing behavior of the UE115, and the bits may be interpreted according to Table 1. For example, if three bits are available, RRC configuration may indicate to the UE115which of the three bits to interpret.

In some examples, the UE115may interpret a WUS for a sensing operation as a S-WUS. If the WUS is not detected, the UE may not transmit or receive sensing reference signals. If the WUS is detected, an RRC configuration may define UE115behavior. For example, if the WUS is detected, the UE115may receive or monitor for only the sensing reference signal, the UE115may only transmit the sensing reference signal, or the UE115may receive and transmit the sensing reference signal. In some examples, the UE115may receive or transmit multiple sensing reference signals, and the sensing reference signals may be configured prior to reception or transmission. The indication may be valid for UE115configurations for transmission or reception of sensing reference signals between two WUS monitoring occasions, irrespective of the DRX on duration (e.g., the sensing reference signal may be outside of the DRX on duration). In some examples, the WUS indication may be valid for UE115configurations for transmission or reception of sensing reference signals between two WUS monitoring occasions and that fully overlap with the DRX on duration.

In some examples, if S-WUS is configured, the interpretation of the wakeup bit indication of the WUS may be redefined as a function of the S-WUS. If the S-WUS is indicating no sensing activity, the wakeup bit may be interpreted as the WUS. If the S-WUS indicates sensing activity (e.g., transmission or reception), the wakeup bit may indicate UE115behavior. For example, if the wakeup bit has a bit value of 1, the UE115may wake up to monitor the PDCCH. If the wakeup bit has a bit value of 0, the UE115may or may not wake up to monitor the PDCCH. In some examples, the UE115may not wake up to monitor the PDCCH. In some other examples, the UE115may wake up to monitor the PDCCH if the sensing reference signal is configured, reception of the sensing reference signal is configured, or any activity is configured. The UE115may wake up to monitor the PDCCH if the sensing reference signal is transmitted or received is during the on duration of the DRX, outside of the on duration, or irrespective of the on duration.

FIG.3illustrates an example of a process flow diagram300that supports techniques for a S-WUS in accordance with one or more aspects of the present disclosure. In some examples, the process flow diagram300may implement or may be implemented by aspects of the wireless communications system100and the wireless communications system200. For example, the process flow diagram300may include a UE115-eand a network entity105-a, which may be examples of corresponding devices described herein.

In the following description of the process flow diagram300, the operations between the UE115-eand the network entity105-amay be performed in different orders or at different times. Some operations may also be left out of the process flow diagram300, or other operations may be added. Although the UE115-eand the network entity105-aare shown performing the operations of the process flow diagram300, some aspects of some operations may also be performed by one or more other wireless devices.

At305, the network entity105-a(e.g., a TRP, sensing entity, etc.) may transmit control signaling indicating a first WUS configuration to the UE115-e. The control signaling may indicate one or more parameters for a WUS associated with a sensing reference signal. In some examples, the one or more parameters may include an RNTI for a group of UEs115including the UE115-e, where receiving the WUS is based on the RNTI.

At310, the network entity105-amay transmit a monitoring activation message, or control message, activating the one or more S-WUS monitoring occasions at the UE115-e. Transmitting the WUS may be based on the control message (e.g., the monitoring activation message) activating the one or more S-WUS monitoring occasions.
