Abstract
Description
DATA COLLECTION CONFIGURATION SCHEMETECHNICAL FIELD
[0001] The present disclosure relates generally to wireless communication, and more particularly, to configuration scheme for data collection.BACKGROUND
[0002] The Third Generation Partnership Project (3GPP) specifies a radio interface referred to as fifth generation (5G) new radio (NR) (5G NR) . An architecture for a 5G NR wireless communication system includes a 5G core (5GC) network, a 5G radio access network (5G-RAN) , a user equipment (5G UE) , etc. The 5G NR architecture seeks to provide increased data rates, decreased latency, and / or increased capacity compared to prior generation cellular communication systems.
[0003] Wireless communication systems, in general, provide various telecommunication services (e.g., telephony, video, data, messaging, etc. ) based on multiple-access technologies, such as orthogonal frequency division multiple access (OFDMA) technologies, that support communication with multiple UEs. Improvements in mobile broadband continue the progression of such wireless communication technologies. For example, data gathering procedure at the UE side, specifically for a UE-side artificial intelligence / machine learning (AI / ML) model training, can be initiated by either the UE or the network entity. If the entity connected to the UE does not provide one or more necessary resource configurations for the data gathering procedure, the UE may transmit a request to the entity requesting for the one or more resource configurations to facilitate measurements and data generations. Although the data collection process may be useful for AI / ML model training purposes, coordinating the resource configuration for the data collection process may be challenging and may require specific resource configuration techniques. For example, a request for one or more resource configurations may be based on specific conditions associated with the UE to initiate the request, and specific parameters associated with the request.
[0004] BRIEF SUMMARY
[0005] The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects. This summary neither identifies key or critical elements of all aspects nor delineates the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.
[0006] Establishing a general framework for enhancing an air interface between a user equipment (UE) and a network entity using an artificial intelligence and machine learning (AI / ML) model may be based on implementing various functions for data collection, model training, etc. During the data collection, input data is collected for the AI / ML model training, validation, and testing of the AI / ML model. The input data collected at the UE-side of the air interface (e.g., Uu communication link) can either be stored locally at the UE or sent to the network entity, such as radio access network (RAN) entities, core network (CN) entities (e.g., access and mobility management function (AMF) , location management function (LMF) , session management function (SMF) , operation administration and maintenance (OAM) entity, over-the-top (OTT) servers, or third-party entities for the model training.
[0007] During the model training stage, the UE or the network entity can perform AI / ML model training and validation, and prepares the data (e.g., pre-processing and cleaning, formatting, etc. ) for the inference stage. The training of the AI / ML model can be performed at the UE-side, at the network-side, or at a combination of the UE-side and the network-side of the air interface. A first AI / ML model that is used to perform a first inference entirely at the UE is considered a UE-side model, whereas a second AI model that is used to perform a second inference at the network entity is referred to as a network entity-side model. Potentially, the UE-side model and the network-side model can be grouped as a one-sided model. For a two-side model, the inference is jointly performed by the UE and the network entity. For example, the UE performs an initial part of the inference, and the network entity performs the remaining part of the inference. Conversely, the network entity can perform the initial part of the inference, and the UE performs the remaining part of the inference.
[0008] For data collection, the UE or the network entity collects input data and may transfer the input data to a model training component, so the model training component can preprocess the data. To collect the input data, the network entity configures resource settings for the UE to facilitate measurement and data generation. Although the data collection process may be useful for AI / ML model training purposes, coordinating the resource configuration for the data collection process may be challenging and may require specific resource configuration techniques. For example, a request for one or more resource configurations may be based on specific conditions associated with the UE to initiate the request, and specific parameters associated with the request.
[0009] Aspects of the present disclosure address the above-noted and other deficiencies by implementing resource configuration techniques. A UE may transmit, to a network entity, a request message requesting a resource configuration associated with a data collection. The UE receives a response message including the resource configuration from the network entity. In an example, the response message includes preferred parameters for the UE to perform the data collection. In another example, the response message includes a prohibit timer that prohibits the UE from further transmitting another request message. In a further example, the UE receives the prohibit timer information before the UE transmits the request message. In yet another example, the UE receives initiation information for initiating the request.
[0010] According to some aspects, the UE transmits to a network entity, a first message indicating at least one of: a data collection capability of the UE or a first request for information associated with the data collection; and receives, from the network entity, a second message indicating at least one of: resource configuration information for the data collection, the resource configuration information being based on the at least one of: the data collection capability of the UE or the first request for information associated with the data collection, or a rejection for the data collection.
[0011] According to some aspects, the network entity obtains at least one of: a data collection capability of a UE or a first request for information associated with the data collection; and transmits, to the UE, a second message indicating at least one of: resource configuration information for the data collection, the resource configuration information being based on the at least one of: the data collection capability of the UE or the first request for information associated with the data collection, or a rejection for the data collection.BRIEF DESCRIPTION OF THE DRAWINGS

[0027] FIG. lA illustrates a diagram 100 of a wireless communications system associated with a plurality of cells 190. The wireless communications system includes user equipments (UEs) 102 and base stations / network entities 104. Some base stations may include an aggregated base station architecture and other base stations may include a disaggregated base station architecture. The aggregated base station architecture utilizes a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node. A disaggregated base station architecture utilizes a protocol stack that is physically or logically distributed among two or more units (e.g., radio unit (RU) 106, distributed unit (DU) 108, central unit (CU) 110) . For example, a CU 110 is implemented within a RAN node, and one or more DUs 108 may be co-located with the CU 110, or alternatively, may be geographically or virtually distributed throughout one or multiple other RAN nodes. The DUs 108 may be implemented to communicate with one or more RUs 106. Any of the RU 106, the DU 108 and the CU 110 can be implemented as virtual units, such as a virtual radio unit (VRU) , a virtual distributed unit (VDU) , or a virtual central unit (VCU) . The base station / network entity 104 (e.g., an aggregated base station or disaggregated units of the base station, such as the RU 106 or the DU 108) , may be referred to as a transmission reception point (TRP) .
[0028] Operations of the base station 104 and / or network designs may be based on aggregation characteristics of base station functionality. For example, disaggregated base station architectures are utilized in an integrated access backhaul (IAB) network, an open-radio access network (O-RAN) network, or a virtualized radio access network (vRAN) , which may also be referred to a cloud radio access network (C-RAN) . Disaggregation may include distributing functionality across the two or more units at various physical locations, as well as distributing functionality for at least one unit virtually, which can enable flexibility in network designs. The various units of the disaggregated base station architecture, or the disaggregated RAN architecture, can be configured for wired or wireless communication with at least one other unit. For example, the base stations 104d, 104e and / or the RUs 106a, 106b, 106c, 106d may communicate with the UEs 102a, 102b, 102c, 102d, and / or 102s via one or more radio frequency (RF) access links based on a Uu interface. In examples, multiple RUs 106 and / or base stations 104 may simultaneously serve the UEs 102, such as by intra- cell and / or inter-cell access links between the UEs 102 and the RUs 106 / base stations 104.
[0029] The RU 106, the DU 108, and the CU 110 may include (or may be coupled to) one or more interfaces configured to transmit or receive information / signals via a wired or wireless transmission medium. For example, a wired interface can be configured to transmit or receive the information / signals over a wired transmission medium, such as via the fronthaul link 160 between the RU 106d and the baseband unit (BBU) 112 of the base station 104d associated with the cell 190d. The BBU 112 includes a DU 108 and a CU 110, which may also have a wired interface (e.g., midhaul link) configured between the DU 108 and the CU 110 to transmit or receive the information / signals between the DU 108 and the CU 110. In further examples, a wireless interface, which may include a receiver, a transmitter, or a transceiver, such as an RF transceiver, configured to transmit and / or receive the information / signals via the wireless transmission medium, such as for information communicated between the RU 106a of the cell 190a and the base station 104e of the cell 190e via cross-cell communication beams 136-138 of the RU 106a and the base station 104e.
[0030] The RUs 106 may be configured to implement lower layer functionality. For example, the RU 106 is controlled by the DU 108 and may correspond to a logical node that hosts RF processing functions, or lower layer PHY functionality, such as execution of fast Fourier transform (FFT) , inverse FFT (iFFT) , digital beamforming, physical random access channel (PRACH) extraction and filtering, etc. The functionality of the RU 106 may be based on the functional split, such as a functional split of lower layers.
[0031] The RUs 106 may transmit or receive over-the-air (OTA) communication with one or more UEs 102. For example, the RU 106b of the cell 190b communicates with the UE 102b of the cell 190b via a first set of communication beams 132 of the RU 106b and a second set of communication beams 134b of the UE 102b, which may correspond to inter-cell communication beams or, in some examples, cross-cell communication beams. For instance, the UE 102b of the cell 190b may communicate with the RU 106a of the cell 190a via a third set of communication beams 134a of the UE 102b and a fourth set of communication beams 136 of the RU 106a. DUs 108 can control both real-time and non-real-time features of control plane and user plane communications of the RUs 106.
[0032] Any combination of the RU 106, the DU 108, and the CU 110, or reference thereto individually, may correspond to a base station 104. Thus, the base station 104 may include at least one of the RU 106, the DU 108, or the CU 110. The base stations 104 provide the UEs 102 with access to a core network. The base stations 104 may relay communications between the UEs 102 and the core network (not shown) . The base stations 104 may be associated with macrocells for higher-power cellular base stations and / or small cells for lower-power cellular base stations. For example, the cell 190e may correspond to a macrocell, whereas the cells whereas the cells 190a, 190b, 190c, and 190d may correspond to small cells. Small cells include femtocells, picocells, microcells, etc. A network that includes at least one macrocell and at least one small cell may be referred to as a “heterogeneous network. ”
[0033] Transmissions from a UE 102 to a base station 104 / RU 106 are referred to as uplink (UL) transmissions, whereas transmissions from the base station 104 / RU 106 to the UE 102 are referred to as downlink (DL) transmissions. Uplink transmissions may also be referred to as reverse link transmissions and downlink transmissions may also be referred to as forward link transmissions. For example, the RU 106d utilizes antennas of the base station 104d of cell 190d to transmit a downlink / forward link communication to the UE 102d or receive an uplink / reverse link communication from the UE 102d based on the Uu interface associated with the access link between the UE 102d and the base station 104d / RU 106d.
[0034] Communication links between the UEs 102 and the base stations 104 / RUs 106 may be based on multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication links may be associated with one or more carriers. The UEs 102 and the base stations 104 / RUs 106 may utilize a spectrum bandwidth of Y MHz (e.g., 5, 10, 15, 20, 100, 400, 800, 1600, 2000, etc. MHz) per carrier allocated in a carrier aggregation of up to a total of Yx MHz, where x component carriers (CCs) are used for communication in each of the uplink and downlink directions. The carriers may or may not be adjacent to each other along a frequency spectrum. In examples, uplink and downlink carriers may be allocated in an asymmetric manner, with more or fewer carriers allocated to either the uplink or the downlink. A primary component carrier and one or more secondary component carriers may be included in the component carriers. The primary component carrier may be associated with a primary cell (PCell) and a secondary component carrier may be associated with a secondary cell (SCell) .
[0035] Some UEs 102, such as the UEs 102a and 102s, may perform device-to-device (D2D) communications over sidelink. For example, a sidelink communication / D2D link utilizes a spectrum for a wireless wide area network (WWAN) associated with uplink and downlink communications. Such sidelink / D2D communication may be performed through various wireless communications systems, such as wireless fidelity (Wi-Fi) systems, Bluetooth systems, Long Term Evolution (LTE) systems, New Radio (NR) systems, etc.
[0036] The UEs 102 and the base stations 104 / RUs 106 may each include a plurality of antennas. The plurality of antennas may correspond to antenna elements, antenna panels, and / or antenna arrays that may facilitate beamforming operations. For example, the RU 106b transmits a downlink beamformed signal based on a first set of communication beams 132 to the UE 102b in one or more transmit directions of the RU 106b. The UE 102b may receive the downlink beamformed signal based on a second set of communication beams 134b from the RU 106b in one or more receive directions of the UE 102b. In a further example, the UE 102b may also transmit an uplink beamformed signal (e.g., sounding reference signal (SRS) ) to the RU 106b based on the second set of communication beams 134b in one or more transmit directions of the UE 102b. The RU 106b may receive the uplink beamformed signal from the UE 102b in one or more receive directions of the RU 106b. The UE 102b may perform beam training to determine the best receive and transmit directions for the beamformed signals. The transmit and receive directions for the UEs 102 and the base stations 104 / RUs 106 may or may not be the same.
[0037] In further examples, beamformed signals may be communicated between a first base station / RU 106a and a second base station 104e. For instance, the base station 104e of the cell 190e may transmit a beamformed signal to the RU 106a based on the communication beams 138 in one or more transmit directions of the base station 104e. The RU 106a may receive the beamformed signal from the base station 104e of the cell 190e based on the RU communication beams 136 in one or more receive directions of the RU 106a. In further examples, the base station 104e transmits a downlink beamformed signal to the UE 102e based on the communication beams 138 in one or more transmit directions of the base station 104e. The UE 102e receives the downlink beamformed signal from the base station 104e based on UE communication beams 130 in one or more receive directions of the UE 102e. The UE 102e may also transmit an uplink beamformed signal to the base station 104e based on the UE communication beams 130 in one or more transmit directions of the UE 102e, such that the base station 104e may receive the uplink beamformed signal from the UE 102e in one or more receive directions of the base station 104e.
[0038] The base station 104 may include and / or be referred to as a network entity. That is, “network entity” may refer to the base station 104 or at least one unit of the base station 104, such as the RU 106, the DU 108, and / or the CU 110. The base station 104 may also include and / or be referred to as a next generation evolved Node B (ng-eNB) , a next generation NB (gNB) , an evolved NB (eNB) , an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS) , an extended service set (ESS) , a TRP, a network node, network equipment, or other related terminology. The base station 104 or an entity at the base station 104 can be implemented as an IAB node, a relay node, a sidelink node, an aggregated (monolithic) base station, or a disaggregated base station including one or more RUs 106, DUs 108, and / or CUs 110. A set of aggregated or disaggregated base stations may be referred to as a next generation-radio access network (NG-RAN) . In some examples, the UE 102a operates in dual connectivity (DC) with the base station 104e and the base station / RU 106a. In such cases, the base station 104e can be a master node and the base station / RU 106a can be a secondary
[0039] Still referring to FIG. lA, in certain aspects, any of the UEs 102 may include a resource configuration request component 140 configured to transmit to a network entity, a first message indicating at least one of: a data collection capability of the UE or a first request for information associated with the data collection; and receive, from the network entity 104, a second message indicating at least one of: resource configuration information for the data collection, the resource configuration information being based on the at least one of: the data collection capability of the UE or the first request for information associated with the data collection, or a rejection for the data collection.
[0040] In certain aspects, any of the base stations 104 or a network entity of the base stations 104 may include a resource configuration response component 150 configured to obtain 202 at least one of: a data collection capability of a UE 102 or a first request for information associated with the data collection; and transmit, to the UE 102, a second message indicating at least one of: resource configuration information for the data collection, the resource configuration information being based on the at least one of: the data collection capability of the UE or the first request for information associated with the data collection, or a rejection for the data collection.
[0041] Accordingly, FIG. lA describes a wireless communication system that may be implemented in connection with aspects of one or more other figures described herein. Further, although the following description may be focused on 5G NR, the concepts described herein may be applicable to other similar areas, such as 5G-Advanced and future versions, LTE, LTE-advanced (LTE-A) , and other wireless technologies, such as 6G.
[0042] FIG. lB illustrates an example illustrating a relationship between functionalities and artificial intelligence / machine learning (AI / ML) models. One trained AI / ML model can be associated with one functionality. Within one functionality, there may be one or multiple AI / ML models. For example, functionality 181 includes AI / ML model 1 182-A, ..., model N 182-N. Optionally, one AI / ML model can be shared with different functionalities. For example, AI / ML model x 184 is shared with functionality i 183 and functionality j 185.
[0043] FIG. 2 is a signaling diagram 200 illustrating communications between a UE 102 and a network entity 104 for resource configuration request and response. The network entity 104 may correspond to a base station or a unit of a base station, such as the RU 106, the DU 108, the CU 110, etc.
[0044] In some embodiments, initially, the UE 102 may transmit 202A, to the network entity 104, (and the network entity 104 may receive 202A from the UE 102) data collection capability report. The data collection capability report may include at least one of: whether to support data collection for UE-side model training, whether to support to transfer the collected data to network entity, use case information for which the UE supports the related data collection, functionality information for which the UE supports the related data collection, vendor information for which the UE supports the related data collection, vendor information with which the collected data can be shared, memory size information to store the collected data, e.g., 64 kilobyte or 128 kilobyte for all data collection at UE side, use case / functionality / network entity specific memory size information to store the related collected data, e.g., N kilobyte for a beam prediction (and channel state information (CSI) compression / prediction) , M kilobyte for positioning.
[0045] As illustrated in FIG. 2, in some examples, the data collection capability information is obtained 202A from the UE 102. In some other examples, the data collection capability information can be obtained from other entities such as, a core network (CN) , other RAN, or operation administration and maintenance (OAM) . Both examples may be implemented separately or combined together. Alternatively, in some other examples, the data collection capability information can be predefined in a specification, e.g., mandatory without explicit signaling.
[0046] In some embodiments, the UE 102 may transmit 202B, to the network entity 104, (and the network entity 104 may receive 202B from the UE 102) a request message. The request message 202B is used to indicate the preferred or expected resource configuration information for the data collection at the UE side.
[0047] The resource configuration information may include at least one of: measurement configuration information, measurement duration time, an indicator to indicate the network entity to configure the resource configuration, network associated ID, use case information, functionality information or the like.
[0048] In the request message, the preferred or expected resource configuration information may include at least one of: preferred or expected measurement configuration information, preferred or expected measurement duration time, an indicator to indicate the network entity 104 to configure the resource configuration, preferred or expected network entity associated ID, preferred or expected use case information, preferred or expected functionality information or the like.
[0049] In some implementations, in the request message, the UE 102 may report that the UE 102 will stop data collection, e.g., for one or multiple functionalities in one or multiple serving cells.
[0050] In some implementations, regarding dynamic memory allocation for the data collection, the UE 102 may report memory information in the request message, e.g., memory size to store the collected data for one or multiple requested functionalities. In some examples, the UE 102 may report the memory information by reporting the requested number of transmission occasions for the reference signal for data collection and number of reference signal resources.
[0051] The preferred or expected measurement configuration information can be used to indicate preferred or expected layer 1 (L1) and / or layer 3 (L3) measurement configuration information. The measurement configuration information may include at least one of: radio access technology (RAT) information (e.g., new radio (NR) , long term evolution (LTE) , sixth generation (6G) or more) , frequency information (e.g., frequency in frequency range 1 (FR1) and / or frequency range 2 (FR2) ) , cell information (e.g., frequency and physical cell identifier, global cell identifier or cell global identifier) , serving cell information (preferred or expected serving cell for data collection when carrier aggregation is configured) , bandwidth information (preferred or expected minimum or maximum bandwidth for the reference signals for data collection) , ports information (preferred or expected number of ports for the reference signals for data collection, which may include number of ports in horizontal and number of ports in vertical) , beam information (e.g., set A and / or set B resource information, CSI resource information) , or other measurement configuration information. In some implementations, the measurement configuration information may be one or multiple configurations for performance monitoring. Thus, the network entity 104 may configure a list of performance monitoring configuration, and UE may request activation or deactivation of one or multiple performance monitoring configuration.
[0052] The preferred or expected measurement duration time can be used to indicate the maximum duration information for the UE to perform data collection, or to indicate the minimum duration information for the network entity 104 to provide the resource configuration.
[0053] The preferred or expected network entity associated ID can be used to explicitly or implicitly indicate the content (s) of network configuration information. In an implicit manner, the network configuration information may be predefined and mapped with one network entity associated ID. Each associated ID may refer to one set of network configuration information. In an explicit manner, the network entity associated ID may include at least one of: the number of the cell antenna, antenna down-tilt, sweeping mode of the beam (s) , or the coverage type of the cell (e.g., macro, micro, small, coverage or traffic cell) , among others. The associated ID may be provided per bandwidth part, per serving cell, or per serving cell group.
[0054] The preferred or expected use case information or preferred or expected functionality information may indicate the use case or functionality for data collection. The use case information can be at least one of the following: spatial domain and / or temporal beam prediction, CSI predication, CSI compression, joint CSI compression and prediction, AI / ML assisted or directed positioning, lower layer triggered mobility (LTM) , L3 mobility or the like.
[0055] For example, the UE may provide the preferred or expected L1 measurement configuration information (e.g., set A and set B resource information) , measurement duration time (e.g., 10 seconds) and use case information (e.g., beam management related training) . This means that the UE prefers the network entity 104 to configure set A and set B resource information for UE to collect data for beam management related training for at least 10 seconds.
[0056] The request messages can be at least one of: radio resource control (RRC) setup request message, RRC resume request message, RRC reestablishment request message, UE assistance information (UAI) message, LTE positioning protocol (LPP) signaling related message, L1 (e.g., uplink control information (UCI) ) / L2 (e.g., medium access control-control element (MAC-CE) related signaling, and other various messages.
[0057] In some embodiments, the UE 102 may transmit 202, to the network entity 104, (and the network entity 104 may receive 202 from the UE 102) , a message including at least one of: the data collection capability report 202A or the request 202B.
[0058] In some embodiments, the UE 102 receives 203, from the network entity 104, (and the network entity 104 transmits 203 to the UE 102) a response message.
[0059] The response messages can be at least one of: RRC setup message, RRC resume message, RRC reestablishment message, RRC reconfiguration message, RRC reject message, RRC release message, LPP signaling related message, L1 (e.g., DCI) / L2 (e.g., MAC-CE) related signaling, and other various messages.
[0060] In some examples, the response message is an acknowledge message in response to the request message, as illustrated in FIG. 2. The response message may be used to indicate the resource configuration information configured by the network entity 104 to the UE for data collection at UE side. As an acknowledge message, the response message may include at least one of: current network associated ID, measurement configuration information for UE to perform data collection, configuration duration time information, use case or functionality information for data collection or the like.
[0061] The configuration duration time information is used to indicate the duration of the resource configuration, or to indicate the temporal pattern of the resource configuration.
[0062] In some implementations, the network entity 104 may configure or activate a measurement gap for data collection, e.g., in the response message. During the measurement gap, the UE 102 may perform measurement for data collection and may refrain from receiving other downlink channels or transmitting uplink channels in the same serving cell or in serving cells in the same band or band combination or cell group. The network entity 104 may further indicate whether a configured measurement gap shall be skipped or not, e.g., for some cell / band / cell group. The network entity 104 may provide such indication by an RRC message, MAC CE, DCI, or an LPP message.
[0063] In some other implementations, the response message is a failure message in response to the request message. The failure message may include the failure cause. The failure cause may include at least one of: invalid or incompatible parameter (s) , e.g., at least one of the parameters in the request message cannot be supported at network entity 104 side, network energy saving state, congestion, or overload, e.g., there is not enough resources to be allocated, capability limitation, e.g., the network entity 104 cannot support the requested the resource configuration, or the like.
[0064] In some other implementations, the response message may include prohibit timer information (which will be described in detail in connection with FIG. 4) .
[0065] The UE 102 may receive 204, from the network entity 104, (and the network entity 104 may transmit 204 to the UE 102) , a reconfiguration message to reconfigure the previous resource configuration or provide new resource configuration information.
[0066] In some implementations, the network entity 104 may send a reconfiguration message to update, suspend, delete, or cancel the previous resource configuration, or provide new resource configuration, e.g., for the first time.
[0067] In some implementations, when the response message is an acknowledgement response message, the reconfiguration message from the network entity 104 can be used to reconfigure the previous resource configuration, as illustrated in FIG. 2.
[0068] In some examples, the reconfiguration message may include delta information, e.g., addition information, removal information, and / or modification information to indicate the UE 102 to derive the updated resource configuration based on the previous resource configuration.
[0069] In some other examples, the reconfiguration message may include indication information to indicate the suspend / deletion / cancellation of the previous resource configuration. Accordingly, the UE 102 will stop the measurement based on the previous resource configuration. Additionally, the UE 102 may delete the stored previous resource configuration information.
[0070] In some implementations, when the response message 203 is a failure response message, the reconfiguration message from the network entity 104 can be used to provide new resource configuration, e.g., for the first time.
[0071] In this disclosure, embodiments of the content of the request and response messages for the resource configuration for the data collection at the UE side is described. These embodiments may provide enhanced UE capability or requirements resulting in efficient data collection at the UE side.
[0072] Referring to FIG. 2, in some embodiments, the UE 102 may perform 230 data collection procedure.
[0073] The order of the procedures 202, 202A, 202B, 203 are merely exemplary, and is not limited to the specific order presented in the signaling diagram above.
[0074] FIG. 3A is a signaling diagram 300 illustrating an example of a prohibit timer-based solution for the resource configuration request according to an embodiment.
[0075] In some embodiments, the prohibit timer can be configured before the initiation of the request, e.g., included in the system information. As illustrated in FIG. 3A, the UE 102 receives 301, from the network entity 104, (and the network entity 104 transmits 301, to the UE 102) , prohibit timer information.
[0076] In some embodiments, the UE starts 305A the prohibit timer according to the prohibit timer information to avoid subsequently redundant request (s) .
[0077] For example, the UE starts 305A the prohibit timer and transmits 302B, to the network entity 104, (and the network entity 104 receives 302B, from the UE 102) , a first request message requesting for the resource configuration. When the prohibit timer is running, the UE 102 is prohibited to initiate or transmit a second request message. The first request message and the second request message may be transmitted for requesting the same or different resource configurations.
[0078] In some embodiments, while the prohibit timer is running, the UE 102 may receive 303, from the network entity, (and the network entity 104 may transmit 303 to the UE 102) a first response message. In one possible design, the description of the first response message may refer to the one in step 203.
[0079] In response to receiving 303 the first response message, the UE 102 acts based on the first response message and stops 305B the prohibit timer. In another possible design, the UE 102 may act based on the first response message, but maintains the prohibit timer until the prohibit timer expires or is stopped, e.g., stopping condition is met.
[0080] In some embodiments, if the timer expires 320, the UE 102 may transmit 302C, to the network entity 104, (and the network entity 104 may receive 302C from the UE 102) , a second request message.
[0081] It can be understood that the request for the resource configuration can also be referred to as resource configuration request and is merely described for illustration.
[0082] FIG. 3B is a signaling diagram 350 illustrating another example of a prohibit timer-based solution for the resource configuration request according to an embodiment. The procedures 301, 302B, 302C, 303, 305A, 305B, 310, and 320 may be similar to procedures 301, 302B, 302C, 303, 305A, 305B, 310, and 320 of FIG. 3A.
[0083] Unlike FIG. 3A, the UE 102 transmits 302B, to the network entity 104, (and the network entity 104 receives 302B, from the UE 102) , a first request message requesting for the resource configuration and starts 305A the prohibit timer.
[0084] FIG. 4 is a signaling diagram illustrating an example of a prohibit timer-based solution for the resource configuration request according to an embodiment. The procedures 302B, 302C, 305A, 305B, and 320 may be similar to procedures 302B, 302C, 305A, 305B, and 320 of FIGs. 3A and 3B.
[0085] In some embodiments, the prohibit timer can be included in the response message. As illustrated in FIG. 4, for example, in response to receiving the first request message, the UE 102 receives 403, from the network entity 104, (and the network entity 104 transmits 403 to the UE 102) , a first response message including the prohibit timer.
[0086] In response to receiving the first response message, the UE starts 305A the prohibit timer.
[0087] FIG. 5 is a signaling diagram 500 illustrating an example of network entity control of the initiation of the resource configuration request from UE according to an embodiment.
[0088] In some embodiments, the network entity 104 has control on the initiation of a request message from the UE 102. This embodiment can be implemented separately or combined with other embodiment (s) as described in the disclosure.
[0089] In some implementations, the network entity 104 transmits 501, to the UE 102, (and the UE 102 receives 501, from the network entity 104) , indication information. The indication information can be used to indicate the UE on the initiation of a request message. Further, the indication information can be used to indicate whether to support a request message for resource configuration, and / or when to allow the UE to initiate a request message, and / or the supported resource configuration information at network-side.
[0090] The indication may be per use case or per functionality. Accordingly, the network entity 104 may provide different indication information for different use cases or functionalities. For example, the network entity 104 may allow the UE 102 to request for resources for the data collection for the CSI compression but may not allow the UE 102 to request for resources for the beam prediction. The indication may be per serving cell or per cell group.
[0091] In some implementations, the indication information may include an indicator to indicate whether the network entity 104 can provide or support the resource configuration information to the UE 102 for data collection at the UE side. There may be 1 bit for the indicator. In some examples, the value 1 / true can indicate that the network entity 104 can provide or support the resource configuration information to UE for data collection at UE side, and vice versa. In another example, the presence of the indicator means that the network entity 104 can provide or support the resource configuration information to UE for data collection at UE side, and vice versa.
[0092] In some implementations, the indication information may include overload information, which is used to indicate whether the network entity 104 is overloaded or congested. The UE can initiate a request message if the network entity 104 is not overloaded or congested. The overload information can be set to low, medium, or high. Alternatively, the overload information can be in form of percentage, which indicates the network load information. Furthermore, the UE may be configured with an overload threshold. If the percentage is above or equal to the threshold, it means the network is overloaded or congested.
[0093] In some implementations, the indication information may include request time information, during which period or since which time the UE can initiate a request message. The request time information can be a time window or a starting time instance (e.g., starting system frame number (SFN) ) .
[0094] In some implementations, the indication information may include configurations on the criteria for UE 102 to determine whether to send the request. In some implementations, the UE 102 may determine to send the request if the UE 102 identifies situations including at least one or multiple of: the cell / beam quality is good enough, e.g., synchronization signal reference signal received power / signal-to-noise and interference ratio (SS-RSRP / SINR) or L1-RSRP / SINR for current cell / beam (current indicated transmission configuration indication (TCI) state) , is above a first threshold; or reference or actual power headroom is above a second threshold.
[0095] The threshold (s) above may be predefined or configured by the network entity 104. The threshold (s) may be configured commonly or separately for different use cases or functionalities.
[0096] For example, the indication information includes prohibit time information and downlink quality, e.g., downlink beam quality. The UE 102 may transmit the request if the prohibit timer expires and the downlink beam quality, e.g., layer 1 reference signal received power (L1-RSRP) or layer 1 signal-to-interference plus noise ratio (L1-SINR) , is above the threshold. Optionally, in some examples, the UE 102 may measure the beam quality from the downlink reference signal indicated in one the of active TCI state, e.g., the first TCI state. In some other examples, the UE 102 may measure the beam quality from the downlink reference signal indicated in one TCI state configured or indicated by the network entity. In some other examples, the UE 102 may measure the beam quality from a set of downlink reference signals, and determine the beam quality based on the minimum or maximum or average beam quality for the set ofdownlink reference signals. The downlink reference signals may be predefined, e.g., the downlink reference signals indicated in active TCI states, or all the SSBs, or configured or indicated by the network entity via RRC signaling, MAC CE or DCI.
[0097] In some implementations, the indication may further configure a list of candidate configurations for data collection, and the UE 102 may request activation or deactivation of one or multiple candidate configurations in the request message. In some examples, if for each candidate configuration for data collection, there is a measurement configuration ID or the UE can derive the measurement configuration ID, e.g., based on the order in the list, the UE 102 may report the measurement configuration ID to request activation or deactivation for the measurement configuration. Then, the network entity 104 response to the UE request may be activation or deactivation of one or multiple configurations for data collection. The network entity 104 may transmit the response by an RRC message, MAC CE, DCI, or LPP message.
[0098] The description of the supported resource configuration information can refer to the description of the resource configuration information in step 202, e.g., with necessary updates.
[0099] In some implementations, the indication information may further indicate the configuration information for the request message. The indication information may further include at least one of the parameters: maximum number of (re) transmissions of the request, duration of the monitoring window for the response to the request, downlink resource for the response to the request or the like. In some implementations, some of the parameters may be predefined.
[0100] The network entity 104 can include the indication information in system information, RRC message, L1 or L2 signaling, paging, LPP signaling or the like.
[0101] In the embodiments of this disclosure, the network entity 104 provides the control information on the initiation of a request message for resource configuration. Accordingly, the network entity 104 can avoid the request message (s) from the UE 102 when the network entity 104 is overloaded or congested.
[0102] FIG. 6 is a flowchart 600 of a prohibit timer-based solution at a UE, where the UE starts the prohibit timer and initiates a first request message, according to an embodiment.
[0103] At block 601, the UE 102 receives the prohibit timer information, which can be used to prohibit the second request message when the prohibit timer is running.
[0104] The prohibit timer information can be included in system information or dedicated signaling from the network entity 104 to the UE 102. The prohibit timer information can indicate the maximum value of the prohibit timer if started.
[0105] In some implementations, the prohibit timer information can be common for all request (s) for resource configuration (s) . When the prohibit timer is running, any second request is not allowed. In some other implementations, the prohibit timer information can be in the granularity of resource configuration, use case, network entity associated ID, measurement configuration, functionality, model or the like. The prohibit timer information may be provided with the granularity information. For example, the UE 102 receives the first prohibit timer of use case 1. When the first prohibit timer is running, the UE 102 is not allowed to initiate the second request of use case 1. The UE can initiate the request for other use cases.
[0106] This prohibit timer information is merely exemplary, illustrative, and explanatory, and are not intended to limit, but to provide further explanation of the prohibit timer information. Additional features such as some transformation or the extension of the prohibit timer information can be implemented. For example, the prohibit timer of granularity 1 is started and running for request 1 of granularity 1. The UE 102 checks whether the prohibit timer of granularity 1 is running before sending the request 2 of granularity 1. If the prohibit timer of granularity 1 is running (yes) , no request 2 of granularity 1 is initiated. The UE 102 can initiate the request (s) of other granularity / granularities. Correspondingly, the UE 102 may start the prohibit timer of the related granularity.
[0107] At block 605A, the UE 102 starts (or restarts) the prohibit timer with a timer value (e.g., maximum value) according to the prohibit timer information as described in block 601.
[0108] It can be understood that at block 605A is the first time the UE 102 starts the prohibit timer. Generally, before the UE 102 starts the prohibit timer at block 605A, the UE 102 may determine whether the prohibit timer is running. If the UE 102 determines the prohibit timer is not running, the UE starts the prohibit timer at block 605A.
[0109] In some implementations, at block 602B, the UE 102 can first initiate the transmission of first request message and then starts (or restarts) the prohibit timer (605A) . In addition, the UE 102 may initially determine that the prohibit timer is not running, then the UE 102 performs steps of block 602B and 605A. The order of 605A and 602B is merely exemplary and illustrative and are not intended to limit other possible implementation (s) .
[0110] In some implementations, when the prohibit timer is running, the UE 102 may stop the prohibit timer upon receiving the response message (as illustrated as Case a in the FIGs. 3A and 3B) . As shown in FIG. 6, for example, at block 620, it can be determined ifthe prohibit timer is running. Ifthe prohibit timer is running, the method 600 proceeds to block 603. At block 603, if it is determined the UE 102 receives the first response message. The method 600 proceeds to block 605B. At block 605B, the UE 102 acts based on first response message and stops the timer.
[0111] At block 603, if it is determined the UE 102 does not receive the first response message. The method 600 proceeds to block 602C. At block 602C, the UE 102 transmits, to the network entity 104, a second request message. This corresponds to Case b in the FIGs. 3A and 3B.
[0112] Still referring to FIG. 6, at block 620, if the prohibit timer is not running, the method 600 proceeds to block 602C. At block 602C, the UE 102 transmits, to the network entity 104, a second request message. In detail, at block 602C, the UE waits for the expiry of the prohibit timer. When the prohibit timer expires, UE 102 transmits, to the network entity 104, a second request message.
[0113] In some implementations, if the UE 102 does not receive a response message, the UE 102 stops prohibit timer when the prohibit timer reaches a maximum value, e.g., the prohibit timer expires (as illustrated as Case b in the FIGs. 3A and 3B) . In some other implementations, if the UE 102 starts or restarts the prohibit timer, the UE 102 will not stop the prohibit timer when the UE 102 receives the response message.
[0114] For Case c, when the UE 102 starts or restarts the prohibit timer, the UE 102 will not stop the prohibit timer regardless of whether the UE 102 receives a response message or not while the prohibit timer is still running. The UE 102 stops the prohibit timer when it expires or is stopped, e.g., the stopping condition is met.
[0115] When the UE 102 determines 620 that the prohibit timer is not running, if needed, the UE 102 can transmit 602C a second request message. The second request message may be the same as the first request message or different than the first message.
[0116] It can be understood that the reception of response message can be a condition for the UE to stop the prohibit timer. The other stopping conditions may include at least one of: upon release the request during reestablishment procedures, upon reception of RRC Release message, upon successful change of PCell while in RRC_CONNECTED state, upon activation of a primary secondary serving cell (PSCell) where the PSCell may correspond to a new frequency band or band combination, upon activation of a secondary cell (SCell) where the SCell may correspond to a new frequency band or band combination, or upon the indication to stop the prohibit timer from the network entity 104.
[0117] FIG. 7 is a flowchart of a prohibit timer-based solution at a UE, where the prohibit timer is configured in the response message, according to an embodiment.
[0118] At block 602B, the UE may transmit to the network entity 104, a first request message. At block 703, the UE 102 receives a first response message including prohibit timer information.
[0119] At block 605A, the UE starts the prohibit timer according to the prohibit timer information. Regarding the description of the prohibit timer, reference may be made to the description of the prohibit timer in connection with previous figures, and details are not repeated herein.
[0120] In some implementations, if the UE 102 does not receive the first response message, the UE 102 may determine the prohibit timer information based on a default configuration, where the default configuration may be predefined or configured by the network entity 104.
[0121] At block 620, it can be determined that the prohibit timer is running. If it is determined that the prohibit timer is running, the method proceeds to block 702D. At block 702D, the UE 102 may not be allowed to transmit, to the network entity 104, a second request message.
[0122] If it is determined that the prohibit timer is not running, the method proceeds to block 602C. At block 602C, the UE 102 may transmit, to the network entity 104, a second request message.
[0123] As described above, the prohibit timer is configured to prevent the UE 102 from transmitting consecutive request (s) for the resource configurations, e.g., for data collection at least for the UE-side model training. Accordingly, the use of prohibit timer can avoid the signaling overhead for the frequent request for the resource configurations.
[0124] FIGs. 2-7 illustrate resource configuration request and response procedures. FIGs. 8A-9B show methods for implementing one or more aspects of FIGs. 2-7. In particular, FIGs. 8A-8B show an implementation by the UE 102 of the one or more aspects of FIGs. 2-7. FIGs. 9A-9B show an implementation by the network entity 104 of the one or more aspects of FIGs. 2-7.
[0125] FIG. 8A illustrates a flowchart 800 of a method of wireless communication at a UE.With reference to FIGs. lA-7, the method may be performed by the UE 102. In embodiments, the UE 102 may receive 80lA, from a network entity 104, prohibit timer information associated with a prohibit timer that prohibits a transmission of a second request for information associated with the data collection. For example, referring to FIGs. 3A-3B, the UE 102 receives 301, from the network entity 104, prohibit timer information.
[0126] In embodiments, the UE 102 may receive 80lB, from the network entity 104, indication information indicating conditions for an initiation of the first request. For example, referring to FIG. 5, UE 102 receives 501, from the network entity 104, indication information.
[0127] In embodiments, the UE 102 transmits 802, to the network entity 104, a first message indicating at least one of: a data collection capability of the UE or a first request for information associated with the data collection. For example, referring to FIG. 2. the UE 102 transmits 202A, to the network entity 104, data collection capability report.
[0128] In embodiments, the UE 102 receives 803, from the network entity 102, a second message indicating at least one of: resource configuration information for the data collection, the resource configuration information being based on the at least one off the data collection capability of the UE or the first request for information associated with the data collection, or a rejection for the data collection. For example, referring to FIG. 2, the UE 102 receives 203, from the network entity, a response message including at least one off current network associated ID, use case / functionality info for data collection, measurement configuration information.
[0129] In embodiments, the UE 102 may receive 804, from the network entity, a reconfiguration message indicating at least one of: an update to a resource configuration for the data collection, a suspension to a resource configuration for the data collection, a deletion to a resource configuration for the data collection, a cancelation to a resource configuration for the data collection, or a new resource configuration for the data collection. For example, referring to FIG. 2, the UE 102 receives 204, from the network entity 104, a reconfiguration message to reconfigure the previous resource configuration or provide new resource configuration information.
[0130] In embodiments, the UE 102 may perform 830 a data collection procedure for the data collection based on the resource configuration. For example, referring to FIG. 2, the UE 102 performs 230 data collection procedure.
[0131] FIG. 8B illustrates a flowchart of a method of wireless communication at a UE in connection with block 802 above.
[0132] In some embodiments, the UE 102 may transmit 802A, to the network entity 104, a UE capability report. For example, referring to FIG. 2, the UE 102 transmits 202A, to the network entity 104, data collection capability report.
[0133] In some embodiments, the UE 102 may transmit 802C-1, to the network entity 104, a second request for information associated with the data collection when a response to the first request has not been received. For example, referring to FIGs. 3A-3B, the UE 102 transmits 302C, to the network entity 104, a second request message if the timer expires 320.
[0134] In some embodiments, the UE 102 may transmit 802C-2, to the network entity 104, the second request for information associated with the data collection. For example, referring to FIGs. 3A-3B, the UE 102 transmits 302C, to the network entity 104, a second request message ifthe UE 102 does not receive a first response message.
[0135] FIGs. 8A-8B describe a method from a UE-side of a wireless communication link, whereas FIGs. 9A-9B describes a method from a network-side of the wireless communication link.
[0136] FIG. 9A is a flowchart 900 of a method of wireless communication at a network entity. With reference to FIGs. lA-7, the method may be performed by one or more network entities 104, which may correspond to a base station or a unit of the base station, such as the RU 106, the DU 108, and / or the CU 110.
[0137] In embodiments, the network entity 104 may transmit 901 A, to a UE 102, prohibit timer information associated with a prohibit timer that prohibits a transmission of a second request for information associated with the data collection. For example, referring to FIGs. 3A-3B, the network entity 104 transmits 301, to the UE 102, prohibit timer information.
[0138] In embodiments, the network entity 104 may transmit 90lB, to the UE 102, indication information indicating conditions for an initiation of the first request. For example, referring to FIG. 5, the network entity 104 transmits 501, to the UE 102, indication information.
[0139] In embodiments, the network entity 104 obtains 902 a first message indicating at least one of: a data collection capability of the UE or a first request for information associated with the data collection. For example, referring to FIG. 2, the network entity 104 receives 202A, from the UE 102, data collection capability report.
[0140] In embodiments, the network entity 104 transmits 903, to the UE 102, a second message indicating at least one of: resource configuration information for the data collection, the resource configuration information being based on the at least one of: the data collection capability of the UE or the first request for information associated with the data collection, or a rejection for the data collection. For example, referring to FIG. 2, the network entity 104 transmits 203, to the UE 102, a response message including at least one of: current network associated ID, use case / functionality info for data collection, measurement configuration information.
[0141] In embodiments, the network entity 104 may transmit 904, to the UE 102, a reconfiguration message indicating at least one of: an update to a resource configuration for the data collection, a suspension to a resource configuration for the data collection, a deletion to a resource configuration for the data collection, a cancelation to a resource configuration for the data collection, or a new resource configuration for the data collection.For example, referring to FIG.2, the network entity 104 transmits 204, to UE 102, a reconfiguration message to reconfigure the previous resource configuration or provide new resource configuration information.
[0142] FIG. 9B is a flowchart of a method of wireless communication at a network entity in connection with block 902 above.
[0143] In some embodiments, the network entity 104 may receive 902A, from the UE 102, data collection capability of the UE. For example, referring to FIG. 2, the network entity 104 receives 202A, from the UE 102, data collection capability report.
[0144] In some embodiments, the network entity 104 may receive 902D, from another entity, data collection capability of the UE. For example, referring to FIG. 2, the network entity 104 receives 202A, from the CN entity, other RAN entities, or OAM.
[0145] In some embodiments, the network entity 104 may obtain 902E the data collection capability of the UE from the predefined in the standards. For example, the data collection capability information can be predefined in the specification, e.g., mandatory without explicit signaling.
[0146] In some embodiments, the network entity 104 may obtain 902B, from the UE, a first request. For example, referring to FIGs. 3A-3B, the network entity 104 receives 302B, from the UE 102, a first request message.

The accompanying method claims present elements of the various blocks in an example order, and are not limited to the specific order or hierarchy presented in the claims, processes, and flowcharts.
[0162] The detailed description set forth herein describes various configurations in connection with the drawings and does not represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough explanation of various concepts. However, these concepts may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring such concepts.
[0163] Aspects of wireless communication systems, such as telecommunication systems, are presented with reference to various apparatuses and methods. These apparatuses and methods are described in the following detailed description and are illustrated in the accompanying drawings by various blocks, components, circuits, processes, call flows, systems, algorithms, etc. (collectively referred to as “elements” ) . These elements may be implemented using electronic hardware, computer software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
[0164] An element, or any portion of an element, or any combination of elements may be implemented as a “processing system” that includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs) , central processing units (CPUs) , application processors, digital signal processors (DSPs) , reduced instruction set computing (RISC) processors, systems-on-chip (SoC) , baseband processors, field programmable gate arrays (FPGAs) , programmable logic devices (PLDs) , state machines, gated logic, discrete hardware circuits, and other similar hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system may execute software, which may be referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, or any combination thereof.
[0165] Ifthe functionality described herein is implemented in software, the functions may be stored on, or encoded as, one or more instructions or code on a computer-readable medium, such as a non-transitory computer-readable storage medium. Computer-readable media includes computer storage media and can include a random-access memory (RAM) , a read-only memory (ROM) , an electrically erasable programmable ROM (EEPROM) , optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of these types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer. Storage media may be any available media that can be accessed by a computer.
[0166] Aspects, implementations, and / or use cases described herein may be implemented across many differing platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, the aspects, implementations, and / or use cases may come about via integrated chip implementations and other non-module-component based devices, such as end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchasing devices, medical devices, artificial intelligence (AI) -enabled devices, machine learning (ML) -enabled devices, etc. The aspects, implementations, and / or use cases may range from chip-level or modular components to non-modular or non-chip-level implementations, and further to aggregate, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more techniques described herein.
[0167] Devices incorporating the aspects and features described herein may also include additional components and features for the implementation and practice of the claimed and described aspects and features. For example, transmission and reception of wireless signals necessarily includes a number of components for analog and digital purposes, such as hardware components, antennas, RF-chains, power amplifiers, modulators, buffers, processor (s) , interleavers, adders / summers, etc. Techniques described herein may be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc., of varying configurations.
[0168] The description herein is provided to enable a person skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other aspects. Thus, the claims are not limited to the aspects described herein, but are to be interpreted in view of the full scope of the present disclosure consistent with the language of the claims.
[0169] Reference to an element in the singular does not mean “one and only one” unless specifically stated, but rather “one or more. ” Terms such as “if, ” “when, ” and “while” do not imply an immediate temporal relationship or reaction. That is, these phrases, e.g., “when, ” do not imply an immediate action in response to or during the occurrence of an action, but simply imply that if a condition is met then an action will occur, but without requiring a specific or immediate time constraint for the action to occur. The terms “may” , “might” , and “can” , as used in this disclosure, often carry certain connotations. For example, “may” refers to a permissible feature that may or may not occur, “might” refers to a feature that probably occurs, and “can” refers to a capability (e.g., capable of) . The phrase “For example” often carries a similar connotation to “may” and, therefore, “may” is sometimes excluded from sentences that include “for example” or other similar phrases.
[0170] Unless specifically stated otherwise, the term “some” refers to one or more. Combinations such as “at least one of A, B, or C” or “one or more of A, B, or C” include any combination of A, B, and / or C, such as A and B, A and C, B and C, or A and B and C, and may include multiples of A, multiples of B, and / or multiples of C, or may include A only, B only, or C only. Sets should be interpreted as a set of elements where the elements number one or more. Terms or articles such as “a” , “an” , and / or “the” may refer to one of an item, feature, element, etc., that the term or article precedes, or may refer to more than one of said item, feature, element, etc. that the term or article precedes. For example, the recitation “a widget” does not preclude reference to multiples of said widget, as “multiple widgets” necessarily includes “a widget” . Hence, the recitation “a widget” may be interpreted as “at least one widget” or, similarly, interpreted as “one or more widgets” .
[0171] Unless otherwise specifically indicated, ordinal terms such as “first” and “second” do not necessarily imply an order in time, sequence, numerical value, etc., but are used to distinguish between different instances of a term or phrase that follows each ordinal term.
[0172] Reference numbers, as used in the specification and figures, are sometimes cross-referenced among drawings to denote same or similar features. A feature that is exactly the same in multiple drawings may be labeled with the same reference number in the multiple drawings. A feature that is similar among the multiple drawings, but not exactly the same, may be labeled with reference numbers that have different leading numbers but have one or more of the same trailing numbers (e.g., 206, 306, 406, etc., may refer to similar features in the drawings) . Hence, like numbers may refer to like actions.
[0173] Structural and functional equivalents to elements of the various aspects described throughout this disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and are encompassed by the claims. The words “module, ” “mechanism, ” “element, ” “device, ” and the like may not be a substitute for the word “means. ” As such, no claim element is to be construed as a means plus function unless the element is expressly recited using the phrase “means for. ” As used herein, the phrase “based on” shall not be construed as a reference to a closed set of information, one or more conditions, one or more factors, or the like. In other words, the phrase “based on A” , where “A” may be information, a condition, a factor, or the like, shall be construed as “based at least on A” unless specifically recited differently.
