[0022] FIG. 1 illustrates a network environment 100 in accordance with some embodiments. The network environment 100 may include a user equipment (UE) 104 communicatively coupled with a base station 108 of a radio access network (RAN) 110. The UE 104 and the base station 108 may communicate over air interfaces compatible with 3GPP TSs such as those that define a Fifth Generation (5G) new radio (NR) system or a later system. The base station 108 may provide user plane and control plane protocol terminations toward the UE 104.
[0023] In some embodiments, the UE 104 and base station 108 may establish data radio bearers (DRBs) to support transmission of data over a wireless link between the two nodes. In one example, these DRBs may be used for traffic from extended reality (XR) applications that contains a large amount of data conveying real and virtual images and audio for presentation to a user. The UE 104 may access an external data network 120 via the base station 108.
[0024] The network environment 100 may further include a core network 112. For example, the core network 112 may comprise a 5th Generation Core network (5GC) or later generation core network. The core network 112 may be coupled to the base station 108 via a fiber optic or wireless backhaul. The core network 112 may provide functions for the UE 104 via the base station 108. These functions may include managing subscriber profile information, subscriber location, authentication of services, or switching functions for voice and data sessions.
[0025] The UE 104 may include a radio resource control (RRC) state machine that perform operations related to a variety of RRC procedures including, for example, paging, RRC connection establishment, RRC connection reconfiguration, and RRC connection release. The RRC state machine may be implemented by protocol processing circuitry, see, for example, processor circuitry 504 of Figure 5 (e.g., baseband processor 504A, which may access communication protocol stack 536) .
[0026] The RRC state machine may transition the UE 104 into one of a number of RRC states (or “modes” ) including, for example, a connected state (RRC connected) , an inactive state (RRC inactive) , and an idle state (RRC idle) . The UE 104 may start in RRC idle when it first camps on an NR cell, which may be after the UE 104 is switched on or after an inter-system cell reselection from a Long Term Evolution (LTE) cell. To engage in active communications, the RRC state machine may transition the UE 104 from RRC idle to RRC connected by performing an RRC setup procedure to establish a logical connection, for example, an RRC connection, with a base station. In RRC connected, the UE 104 may be configured with at least one signaling radio bearer (SRB) for signaling (for example, control messages) with the base station; and one or more data radio bearers (DRBs) for data transmission. When the UE 104 is less actively engaged in network communications, the RRC state machine may transition the UE 104 from RRC connected to RRC inactive using an RRC release procedure. The RRC inactive state may allow the UE 104 to reduce power consumption as compared to RRC connected, but will still allow the UE 104 to quickly transition back to RRC connected to transfer application data or signaling messages.
[0027] A network may transmit paging messages in order to reach UEs that are in RRC idle or RRC inactive states. The UE 104 may include a main radio 122 and a wakeup radio (WUR) 124 (also referred to as a wake-up receiver or a low-power WUR (LP-WUR) ) . The main radio 122 may include radio frequency (RF) and modulator / demodulator components configured to perform primary receive and transmit operations in the course of communicating with the network device 104. Some of these receive / transmit operations are discussed in more detail with respect to UE 500 of FIG. 5. The WUR 124 may be a relatively low-complexity receiver that is designed to specifically detect a wakeup signal (WUS, also referred to as a low power WUS (LP-WUS) ) transmitted by the RAN 110 (e.g., the base station 108) .
[0028] When not engaged in communications (e.g., receiving signals from or transmitting signals to the RAN 110) , the main radio 122 may transition to a reduced-power state and the UE 104 may activate the WUR 124. The WUR 124 may monitor for the WU-Sin respective wakeup occasions. Upon detecting the WU-S, the WUR 124 may provide a trigger to wake up the main radio 122 (e.g., transition the main radio 122 to a higher power state) . The primary component radio 112 may then power up to receive paging or other messages from the RAN 110 and the WUR 124 may power down. The WUR 124 may provide significant power savings for the UE 104 compared with having the primary component radio 112 powering on to periodically monitor for paging messages in paging occasions, which may rarely be detected.
[0029] The WUR 124 may further provide some radio resource monitoring (RRM) functionality, e.g., offloaded to the main radio 122 so that the main radio 122 can stay in the low power state. For example, the serving cell of the UE 104 may transmit a low power –synchronization signal (LP-SS) . The LP-SS may be designed to be measured by the low-complexity WUR 124. The WUR 124 may perform one or more measurements on the LP-SS. If the one or more measurements indicate that a signal quality of the serving cell is poor (e.g., the one or more measurements are below a threshold) , the WUR 124 may trigger the main radio 122 to wake up to perform additional RRM (e.g., perform additional measurements on the serving cell, perform measurements on one or more neighboring cells, and / or initiate a handover procedure to transition the serving cell from a source cell to a target cell) . The main radio may perform RRM measurements on a synchronization signal block (SSB) .
[0030] The main radio 122 may be in one of a plurality of measurement modes associated with a low power state. For example, in a first measurement mode, the serving cell measurements may be fully offloaded from the main radio 122 and instead performed by the WUR 124 (e.g., on the LP-SS) . The main radio 122 may still perform measurements on neighboring cells. In a second measurement mode, the main radio 122 may perform serving cell measurements with relaxed measurement parameters (e.g., a longer measurement period) compared with a high power state. In some instances, the WUR 124 may still perform serving cell measurements on the LP-SS in the second measurement mode.
[0031] Existing techniques for WUR-based RRM are only applicable for 3GPP Frequency Range 1 (FR1) . Furthermore, existing techniques do not address receive beam sweeping that may be needed for higher frequencies. Various embodiments herein provide techniques for WUR-based RRM in 3GPP Frequency Range 2 (FR2) , such as FR2 subband 1 (FR2-1) . For example, embodiments include mechanisms for receive beam sweeping for WUR-based RRM. Additionally, embodiments include configuration of quasi-co-location (QCL) information between a SSB and a LP-SS.
[0032] Receive beam sweeping
[0033] In various embodiments, a UE (e.g., UE 104) may perform receive beam (Rx beam) sweeping with the WUR (e.g., WUR 124) on LP-SS to perform measurements for the serving cell in FR2 (e.g., FR2-1) . With Rx beam sweeping, the WUR may receive the LP-SS using different Rx beams. The Rx beam sweeping factor (N1) may correspond to the number of Rx beams that are used to receive the LP-SS. The UE may perform a measurement on the LP-SS that is received with the respective Rx beams. The embodiments for Rx beam sweeping described herein may generally apply to FR2 and, more specifically, FR2-1.
[0034] In some embodiments, the Rx beam sweeping factor may be based on a periodicity of the LP-SS. For example, the Rx beam sweeping factor may be smaller for a longer LP-SS periodicity.
[0035] In some embodiments, the Rx beam sweeping factor may additionally or alternatively be based on whether QCL information (e.g., QCL type D information) is configured to associate the LP-SS with a SSB. If QCL information is configured, the UE may perform Rx beam sweeping within a rough beam that corresponds to the SSB. If QCL information is not configured, the UE may perform Rx beam sweeping over a broader spatial spectrum (e.g., a sphere) . Accordingly, the Rx beam sweeping factor may be greater when QCL information is not configured for the LP-SS than when QCL information is configured. For example, in some embodiments, the Rx beam sweeping factor may be greater than or equal to 8 when QCL information is not configured, and may be less than 8 when QCL information is configured.
[0036] Table 1 illustrates example Rx beam sweeping factors (N1) for different LP-SS periodicities in accordance with some embodiments herein. In a first embodiment (Embodiment 1) , the Rx beam sweeping factor may be based on the periodicity of the LP-SS. As shown, a Rx beam sweeping factor of 8 may be used for a LP-SS periodicity of 0.32 seconds (s) , a Rx beam sweeping factor of 5 may be used for a LP-SS periodicity of 0.64s, a Rx beam sweeping factor of 4 may be used for a LP-SS periodicity of 1.28s, and / or a Rx beam sweeping factor of 3 may be used for a LP-SS periodicity of 2.56s. The values of the LP-SS periodicity and Rx beam sweeping factor in Table 1 are merely examples, and other values of the LP-SS periodicity and / or the corresponding Rx beam sweeping factor may be used in accordance with various embodiments.
[0037] In some instances, the UE may receive configuration information (e.g., via broadcast and / or unicast signaling) that indicates the periodicity of the LP-SS and / or other parameters of the LP-SS. The configuration information may indicate the Rx beam sweeping factor to use, or the UE may determine the Rx beam sweeping factor based on a predefined association between the LP-SS periodicity and the Rx beam sweeping factor (e.g., as shown in Table 1) .
[0038] In some embodiments, the Rx beam sweeping factors for Embodiment 1 of Table 1 may be used based on QCL information being configured for the LP-SS. The QCL information may enable the UE to perform Rx beam sweeping within a rough beam (e.g., corresponding to an QCLed SSB) with a Rx beam sweeping factor less than 8.
[0039] In a second embodiment (Embodiment 2) and a third embodiment (Embodiment 3) illustrated in Table 1, the Rx beam sweeping factor may be the same for different LP-SS periodicities (e.g., all of the LP-SS periodicities indicated in Table 1) . In Embodiment 2, the Rx beam sweeping factor may be greater than or equal to 8. In some instances, an Rx beam sweeping factor greater than or equal to 8 may be used if QCL information is not configured for the LP-SS (e.g., the UE performs Rx beam sweeping over a sphere) .
[0040] In Embodiment 3, the Rx beam sweeping factor may be less than 8. In some instances, an Rx beam sweeping factor less than 8 may be used if QCL information (e.g., QCL type D information) is configured for the LP-SS. The UE may perform Rx sweeping within a rough beam based on the QCL information. For example, the rough beam may correspond to a SSB beam of a SSB that is QCLed with the LP-SS.
[0041] Table 1
[0042] In some embodiments, the Rx beam sweeping factor may be based on a capability of the UE. For example, the UE may provide UE capability information to the network that indicates a maximum number of Rx beams supported by the UE for Rx beam sweeping (e.g., maxNumberRxBeam) . The network may configure the Rx beam sweeping factor for the UE (e.g., to be less than or equal to the maximum number of Rx beams indicated by the UE) .
[0043] In various embodiments, the LP-SS may be transmitted in respective LP-SS occasions. In some embodiments, the LP-SS may additionally have multiple repetitions transmitted within individual LP-SS occasions. For example, the LP-SS may be transmitted in different LP-SS occasions with different transmit beams (Tx beams) and the repetitions of the LP-SS within the same LP-SS occasion may be transmitted with the same Tx beam.
[0044] In some embodiments, the UE (e.g., the WUR of the UE) may perform Rx beam sweeping among the LP-SS repetitions within a LP-SS occasion. Accordingly, the total number of LP-SS occasions needed for the Rx beam sweeping may be reduced.
[0045] For example, the number of LP-SS occasions needed to perform Rx beam sweeping may correspond to: ceil (NumberRxBeam / (number of repetitions per occasion) ) , where NumberRxBeam is the number of Rx beams that are used to receive the LP-SS. The number of Rx beams may correspond to the Rx beam sweeping factor described above (e.g., may be determined according to Table 1) . In some embodiments, the number of Rx beams may be indicated from the UE to the network, configured for the UE by the network, or predefined (e.g., in the 3GPP specification) . In some instances, the UE may obtain multiple measurement samples for individual receive beams, so the total number of measurements may be the number of Rx beams multiplied by the number of measurement samples per Rx beam.
[0046] In some embodiments, the network may configure whether or not the UE performs Rx beam sweeping among LP-SS repetitions within an individual LP-SS occasion. For example, the network may transmit an indication to the UE to enable or disable the UE to perform Rx beam sweeping among LP-SS repetitions within an individual LP-SS occasion. The indication may be included for example, in a RRC configuration and / or a system information (SI) configuration (e.g., a LP-SS measurement configuration) . In embodiments, the main radio of the UE may be used to receive configuration information that configures the WUR of the UE.
[0047] QCL information between SSB and LP-SS
[0048] As discussed above, in some embodiments QCL information (e.g., QCL type D information) may be configured for a LP-SS to indicate that the LP-SS is QCLed with a SSB. The SSB may be received by the main radio of the UE. The main radio may acquire beam information on the SSB, e.g., via Rx beam sweeping on the SSB.
[0049] The WUR of the UE may perform Rx beam sweeping on the LP-SS based on the QCL information. For example, the WUR of the UE may perform Rx beam sweeping within a rough beam that corresponds to the beam of the SSB (e.g., using finer / narrower Rx beams than the beam associated with the SSB) .
[0050] In some embodiments, the UE may receive configuration information from the network to indicate the QCL information between the LP-SS and the SSB. For example, the configuration information may indicate that LP-SS index i is QCLed type D with SSB index j.
[0051] In some embodiments, the QCL information may be for a cell-specific SSB. For example, the configuration information may indicate that LP-SS index i is QCLed type D with SSB index j of cell s.
[0052] In some embodiments, the QCL information may be for a SSB of a specific component carrier (e.g., frequency band) . For example, the configuration information may indicate that LP-SS index i is QCLed type D with SSB index j on carrier / frequency k.
[0053] In some embodiments, the WUR behavior for Rx beam sweeping on LP-SS may depend on whether current or recent beam information on the SSB is available. For example, the Rx beam sweeping on LP-SS may be based on the status of the main radio (e.g., whether the main radio is off with serving cell measurement fully offloaded to the WUR or whether the main radio is in a relaxed measurement mode for the serving cell measurement) .
[0054] In a first example scenario, the serving cell measurement may be fully offloaded from the main radio to the WUR (e.g., the WUR is off and serving cell measurement (or sufficiently recent serving cell measurement) of the SSB is available) . In some embodiments with the first example scenario, the WUR of the UE may perform full (e.g., spherical) LP-SS Rx beam sweeping regardless of whether QCL information is configured for the LP-SS. In such embodiments, the network may not need to configure QCL information between the LP-SS and the SSB.
[0055] In other embodiments, if QCL information is configured for the LP-SS, the WUR of the UE may perform LP-SS Rx beam sweeping based on the QCL information (e.g., within the SSB Rx beam direction) , even though more specific beam information for the SSB is not available. In some embodiments, the Rx beam sweeping factor may be reduced based on the QCL information being configured.
[0056] In a second example scenario, the main radio may be in a relaxation mode with respect to serving cell measurements. Accordingly, the main radio may perform some measurements on the serving cell, but the frequency of the measurements may be reduced compared with a higher power mode. The main radio may perform Rx beam sweeping on the SSB to obtain SSB beam information. In some embodiments, the UE (e.g., the WUR) may further perform Rx beam sweeping on the LP-SS based on the SSB beam information (e.g., LP-SS Rx beam sweeping within the SSB beam) .
[0057] In other embodiments, the UE may not perform Rx beam sweeping on the LP-SS if the SSB beam information is available. For example, the UE may use the SSB beam identified from the SSB Rx beam sweeping as the Rx beam to receive the LP-SS.
[0058] In other embodiments, the UE may perform Rx beam sweeping on the LP-SS with a reduced beam sweeping factor based on the availability of the SSB beam information. In yet other embodiments, the UE may perform full LP-SS Rx beam sweeping (e.g., without relying on the SSB beam information) .
[0059] QCL information between LP-WUS and LP-SS
[0060] In some embodiments, the UE may receive QCL information (e.g., QCL type D information) between a LP-WUS and a LP-SS. For example, the QCL information may indicate that LP-WUS x is QCLed type D with LP-SS y. The UE may perform Rx beam sweeping on the LP-SS to obtain beam information and use the beam information to monitor for the LP-WUS in a wakeup occasion. For example, the UE may identify a first Rx beam with a best quality among the Rx beams used for Rx beam sweeping on the LP-SS, and may use the first Rx beam to monitor for the LP-WUS (e.g., to receive the LP-WUS) . The UE may additionally perform time and / or frequency tracking on the LP-SS, which may be used to monitor for and / or receive the LP-WUS.
[0061] In some embodiments, multiple LP-SSs may be configured for the UE. In embodiments, the UE may prioritize Rx beam sweeping and measurement for a LP-SS for which QCL information is configured with reference to a LP-WUS (e.g., a LP-SS that is QCLed with a LP-WUS) .
[0062] For example, the UE may use a shorter LP-SS measurement period or Rx beam sweeping factor for the prioritized LP-SS compared to another LP-SS. Additionally, or alternatively, if LP-SS occasions of different LP-SSs collide (e.g., occupy overlapping resources or otherwise cannot both be received) , the UE may receive and measure the prioritized LP-SS and not the other LP-SS.
[0063] Example operation flow / algorithmic structures
[0064] FIG. 2 illustrates an operation flow / algorithmic structure 200 in accordance with some embodiments. The operation flow / algorithmic structure 200 may be performed by a UE, such as UE 104, UE 500, or components therein, for example, baseband processor 504A.
[0065] The operation flow / algorithmic structure 200 may include, at 204, identifying whether QCL information is configured between a LP-SS and an SSB. For example, the UE may receive QCL information from the network. The SSB and LP-SS may be transmitted in the same cell or different cells. In some embodiments, the QCL information may be associated with a cell, a cell group, and / or a frequency band. In some embodiments, the LP-SS may be in FR2, e.g., FR2-1.
[0066] The operation flow / algorithmic structure 200 may further include determining, based on the identification, a number of receive beams to use for respective measurements on the LP-SS. For example, the UE may use a smaller number of receive beams if QCL information is configured for the LP-SS. In one example, the number of receive beams may be less than 8 if the QCL information is configured and 8 or more if the QCL information is not configured. In some embodiments, the number of receive beams may be determined further based on a periodicity of the LP-SS. For example, the number of receive beams may be smaller for a longer periodicity (e.g., to reduce the overall time to obtain the measurements for the longer periodicity) .
[0067] The operation flow / algorithmic structure 200 may further include, at 212, obtaining, via a wakeup radio, the measurements on the LP-SS. The measurements may be obtained using Rx beam sweeping with the determined number of Rx beams. For example, if the QCL information is configured, the UE may perform Rx beam sweeping on the LP-SS within a SSB beam associated with the SSB (e.g., based on the QCL information) . In some instances, the main radio of the UE may perform SSB measurements (e.g., with Rx beam sweeping) on the SSB. The SSB measurements may be used to determine the SSB beam.
[0068] FIG. 3 illustrates another operation flow / algorithmic structure 300 in accordance with some embodiments. The operation flow / algorithmic structure 300 may be performed by a UE, such as UE 104, UE 500, or components therein, for example, baseband processor 504A.
[0069] The operation flow / algorithmic structure 300 may include, at 304, receiving QCL information between a LP-SS and an SSB.
[0070] The operation flow / algorithmic structure 300 may further include, at 308, identifying a measurement mode of the main radio. For example, the measurement mode may be a first mode in which serving cell measurements are fully offloaded to the wakeup radio or a second mode in which the main radio performs serving cell measurements on the SSB.
[0071] The operation flow / algorithmic structure 300 may further include, at 312, configuring a number of receive beams for the wakeup radio to use for receive beam sweeping on the LP-SS based on the measurement mode.
[0072] FIG. 4 illustrates another operation flow / algorithmic structure 400 in accordance with some embodiments. The operation flow / algorithmic structure 400 may be performed by a UE, such as UE 104, UE 500, or components therein, for example, baseband processor 504A.
