UE-INITIATED BEAM MEASUREMENT REPORTING DELAY ESTIMATIONTECHNICAL FIELD
[0001] The present disclosure relates generally to wireless communication, and more specifically to user equipment (UE) -initiated beam measurement reporting delay estimation.BACKGROUND
[0002] Wireless communication networks provide integrated communication platforms and telecommunication services to wireless user devices. Example telecommunication services include telephony, data (e.g., voice, audio, and / or video data) , messaging, and / or other services. The wireless communication networks have wireless access nodes that exchange wireless signals with the wireless user devices using one or more wireless network protocols, such as protocols described in various telecommunication standards promulgated by the European Telecommunications Standards Institute (ETSI) Third Generation Partnership Project (3GPP) . The wireless communication networks facilitate mobile broadband service using technologies such as orthogonal frequency-division multiple access (OFDMA) , multiple-input multiple output (MIMO) , advanced channel coding, massive MIMO, beamforming, and / or other features.SUMMARY
[0003] The present disclosure generally relates to radio resource management (RRM) techniques for user equipment (UE) -initiated beam measurement reporting delay estimation. Some aspects of the present disclosure involve determining a measurement period for reporting delay estimation based at least on a reference signal configuration of a first beam and a reference signal configuration of a second beam; receiving reference signals via the first beam and the second beam during the measurement period; and transmitting a beam measurement report in response to determining that measurements of the reference signals received during the measurement period satisfy one or more criteria.
[0004] The details of one or more embodiments of the present disclosure are set forth in the accompanying drawings and the description below. Other features, objects, and advantages will be apparent from the description and drawings, and from the claims. BRIEF DESCRIPTION OF THE FIGURES

[0007] FIGs. 6 and 7 illustrate flowcharts of example methods for UE-initiated beam measurement reporting delay estimation, according to some implementations.

[0009] FIG. 9 illustrates an example access node, according to some implementations.DETAILED DESCRIPTION
[0010] A user equipment (UE) may be configured to transmit a beam measurement report when a trigger condition or event is detected. For example, ifthe UE is communicating with an access node (e.g., a base station such as a gNB or an eNB) using a first beam, the UE may transmit a beam measurement report if the quality of a second beam exceeds the quality of the first beam by a threshold margin, or if the quality of the first beam drops below a threshold value. In some implementations, the UE can transmit the beam measurement report using dynamic uplink resources scheduled by the access node. In other implementations, the UE can transmit the beam measurement report using pre-configured uplink resources. In both scenarios, the UE may transmit a physical uplink control channel (PUCCH) before transmitting the beam measurement report. For delay estimation purposes, it may be desirable to know the maximum time period between when the trigger condition / event occurs and when the PUCCH is transmitted. However, this time period can vary based on different factors.
[0011] In accordance with aspects of the present disclosure, the UE may be configured to determine the maximum (e.g., worst case) reporting delay based on at least one of a periodicity of first reference signals associated with the first (e.g., current) beam, a periodicity of second reference signals associated with the second (e.g., new) beam, or a number of samples used to measure the first beam and / or the second beam. In some implementations, the UE may determine the reporting delay based on the measurement period between when the trigger condition is met and an event is triggered based on reference signal measurement (s) . This measurement period may depend on (i) whether the first reference signals and the second reference signals are in the same slot or different slots and (ii) whether the first reference signals and the second reference signals are overlapping or adjacent within the same slot (e.g., an uplink / downlink signal transmission slot) . Ifthe first reference signals or the second reference signals overlap with a measurement gap, a synchronization signal block (SSB) -based measurement timing configuration (SMTC) occasion, or an L1-RSRP measurement, the measurement period may also depend on a sharing factor.
[0012] FIG. 1 illustrates an example wireless network 100, according to some implementations. The wireless network 100 includes a UE 102 and a base station 104, which are connected via one or more channels 106A, 106B across an air interface 108. The UE 102 and base station 104 communicate using a system that supports controls for managing the access of the UE 102 to a network via the base station 104.
[0013] In some implementations, the wireless network 100 is a Standalone (SA) network, e.g., that incorporates fifth generation (5G) New Radio (NR) . In some other implementations, the wireless network 100 is a non-standalone (NSA) network that incorporates Long Term Evolution (LTE) and 5G NR. In these implementations, the wireless network 100 may be an Evolved Universal Terrestrial Radio Access (E-UTRA) NR dual connectivity (EN-DC) network, or an NR-EUTRA dual connectivity (NE-DC) network. Furthermore, wireless networks implementing one or more other types of communication standards are possible, including future 3GPP systems (e.g., sixth generation “6G” ) , Institute of Electrical and Electronics Engineers (IEEE) 802.11 technology, or the like. While aspects may be described herein using terminology commonly associated with 5G NR, aspects of the present disclosure can be applied to other systems, such as systems subsequent to 5G (e.g., 6G) .
[0014] In the wireless network 100, the UE 102 and any other UE in the system may be, for example, any of a laptop computer, smartphone, tablet computer, machine-type device (such as smart meters or specialized devices for healthcare) , intelligent transportation system, or any other wireless device. In the wireless network 100, the base station 104 provides the UE 102 network connectivity to a broader network (not shown) . This UE 102 connectivity is provided via the air interface 108 in a base station service area provided by the base station 104. In some implementations, such a broader network may be a wide area network operated by a cellular network provider, or may be the Internet. Each base station service area associated with the base station 104 is supported by one or more antennas integrated with the base station 104. The service areas can be divided into a number of sectors associated with one or more particular antennas. Such sectors may be physically associated with one or more fixed antennas or may be assigned to a physical area with one or more tunable antennas or antenna settings adjustable in a beamforming process used to direct a signal to a particular sector.
[0015] The UE 102 includes control circuitry 110 coupled with transmit circuitry 112 and receive circuitry 114. The transmit circuitry 112 and receive circuitry 114 may each be coupled with one or more antennas. The control circuitry 110 may include application-specific circuitry, baseband circuitry, or any of various combinations thereof. The transmit circuitry 112 and receive circuitry 114 may be adapted to transmit and receive data, respectively, and may include radio frequency (RF) circuitry and / or front-end module (FEM) circuitry.
[0016] In various implementations, aspects of the transmit circuitry 112, receive circuitry 114, and / or control circuitry 110 may be integrated in various ways to implement the operations described herein. The control circuitry 110 may be adapted or configured to perform various operations, such as those described elsewhere in this disclosure related to a UE. For example, the control circuitry 110 can determine a measurement period for UE-initiated / event-driven beam measurement reporting based on a periodicity of reference signals associated with a first / second beam, a number of samples used for measurements of the first / second beam, and so on.
[0017] The transmit circuitry 112 can perform various operations described herein. For example, the transmit circuitry 112 can transmit a PUCCH to request uplink resources for a UE-initiated / event-driven beam measurement report. Additionally, the transmit circuitry 112 may transmit using a plurality of multiplexed uplink physical channels. The plurality ofuplink physical channels may be multiplexed, e.g., according to time division multiplexing (TDM) or frequency division multiplexing (FDM) , and in some implementations, along with carrier aggregation (CA) . The transmit circuitry 112 may be configured to receive block data from the control circuitry 110 for transmission on the air interface 108.
[0018] The receive circuitry 114 can perform various operations described herein. For example, the receive circuitry 114 can receive one or more reference signals (such as an SSB) via a first beam and a second beam during a measurement period that depends on a reference signal periodicity of the first beam and / or the second beam. Additionally, the receive circuitry 114 may receive a plurality of multiplexed downlink physical channels from the air interface 108 and relay the physical channels to the control circuitry 110. The plurality of downlink physical channels may be multiplexed, e.g., according to TDM or FDM, e.g., along with CA. The transmit circuitry 112 and the receive circuitry 114 may transmit and receive, respectively, both control data and content data (e.g., messages, images, video, and the like) structured within data blocks that are carried by the physical channels.
[0019] FIG. 1 also illustrates the base station 104. In some implementations, the base station 104 may be a 5G radio access network (RAN) , a next generation RAN, a E-UTRAN, a non-terrestrial cell, or a legacy RAN, such as a UTRAN. As used herein, the term “5G RAN” or the like may refer to the base station 104 that operates in an NR wireless network 100, and the term “E-UTRAN” or the like may refer to a base station 104 that operates in an LTE wireless network 100. The UE 102 utilizes connections (or channels) 106A, 106B, each of which includes a physical communications interface or layer.
[0020] The base station 104 circuitry may include control circuitry 116 coupled (directly or indirectly) with transmit circuitry 118 and / or receive circuitry 120. The transmit circuitry 118 and receive circuitry 120 may each be coupled (directly or indirectly) with one or more antennas that may be used to enable communications via the air interface 108. The transmit circuitry 118 and receive circuitry 120 may be adapted to transmit and receive data, respectively, addressed to any UE connected to the base station 104. The receive circuitry 120 may receive a plurality of uplink physical channels from one or more UEs, including the UE 102.
[0021] In FIG. 1, the one or more channels 106A, 106B are illustrated as an air interface to enable communicative coupling, and can be consistent with cellular communications protocols, such as an LTE protocol, advanced LTE (LTE-A) protocol, LTE-based access to unlicensed spectrum (LTE-U) , NR protocol, NR-based access to unlicensed spectrum (NR-U) protocol, and / or any other communications protocol (s) . In some implementations, the UE 102 may directly exchange communication data via a ProSe interface. The ProSe interface may alternatively be referred to as a sidelink interface and may include one or more logical channels, including but not limited to a physical sidelink control channel (PSCCH) , a physical sidelink discovery channel (PSDCH) , and a physical sidelink broadcast channel (PSBCH) .
[0022] The techniques described herein generally relate to radio resource management (RRM) constraints for UE-initiated beam management reporting delay. Aspects of the present disclosure provide enhancements to facilitate UE-initiated / event-driven beam management with reduced overhead and / or latency using a unified transmission configuration indicator (TCI) and leveraging existing channel state information (CSI) measurement techniques and reporting configuration framework (s) . The enhancements described herein target frequency range 2 (FR2) and single transmission-reception point (sTRP) with intra-and inter-cell beam management. However, the described techniques can also be applied to frequency range 1 (FR1) and L1 / L2-triggered inter-cell mobility. The present disclosure involves uplink signaling content and / or procedures for UE-initiated / event-driven beam reporting to facilitate fast beam switching. The present disclosure also relates to an uplink signaling medium / container (considering the UE-initiated / event-driven nature of the uplink transmission) for beam reporting.
[0023] In some implementations, UE-initiated beam measurement is triggered when the quality (e.g., L1-RSRP) of at least one new beam becomes a threshold value better than the current beam. This threshold may be configured by RRC signaling. The current beam may correspond to the indicated TCI state. New beams for measurement may be configured by the network (e.g., the base station 104) . In other implementations, UE-initiated beam measurement is triggered when the quality (e.g., L1-RSRP) of the current beam is worse than a configured threshold, or when the quality of at least one new beam becomes a threshold value better than a reference signal derived from the activated TCI state with the Mth best quality.
[0024] The current beam reporting framework supports two different reporting modes. In mode A, the network dynamically schedules resources for transmission of uplink control information (UCI) . In mode A, the UE 102 transmits a first PUCCH (one-bit or multi-bit) to request a resource for a second uplink channel. The UE 102 detects a downlink control information (DCI) format indicating the requested resource for the second uplink channel. The UE 102 transmits a beam measurement report using the second uplink channel. In mode B, UCI is transmitted using resources that are pre-configured for the second uplink channel. In mode B, the UE 102 transmits a first PUCCH (one-bit or multi-bit) to inform the network of the second uplink channel carrying the beam measurement report. The UE 102 transmits the beam measurement report using the second uplink channel indicated by the first PUCCH.
[0025] For purposes of event-triggered measurement reporting delay estimation, the start point may be defined as the time at which the event occurs over-the-air (e.g., when the L1-RSRP of the current beam drops below a threshold) , similar to layer 3 (L3) event-triggered reporting. The end point is defined as the point when the UE 102 transmits a first PUCCH triggered by the event. The aforementioned RRM constraints may be applicable to all events and reporting modes (Mode A and Mode B) . Some aspects of the present disclosure leverage channel state information reference signal (CSI-RS) -based UE-initiated beam measurement L1-RSRP constraints for periodic CSI-RS.
[0026] If UE-initiated beam measurement is triggered when the quality (e.g., L1-RSRP) of at least one new beam becomes a threshold value better than the current beam, the UE 102 may be configured to measure both the current beam and new beam after the starting point (as defined above) . RRM delay constraints may not depend on the sum of the current beam measurement period and the new beam measurement period. In some implementations, RRM delay constraints are defined based on configured measurement resources for a beam measurement report. The UE 102 may be configured to perform continuous measurements of new beams and report when criteria are met (such as one of the events discussed above) . The UE 102 can use SSB or CSI-RS for measurements of the new beam. However, the UE should use the same reference signal type for the current beam and the new beam.
[0027] In some implementations, the new beam and the current beam have the same reference signal periodicity. In other implementations, the new beam and the current beam have different reference signal periodicities. In some implementations, reference signals associated with the current beam and reference signals associated with the new beam are located in different slots. In other implementations, reference signals associated with the current beam and reference signals associated with the new beam are located in the same slot. Ifthe reference signals are located in the same slot, the reference signals associated with the new beam may be adjacent to the reference signals associated with the current beam. Additionally or alternatively, the reference signals associated with the new beam may partially or fully overlap with the reference signals associated with the new beam. Additionally or alternatively, there may be a gap between the reference signals associated with the new beam and the reference signals associated with the current beam.
[0028] In some implementations, the beam measurements performed by the UE 102 are based on a single reference signal instance (referred to hereinafter as single shot) . In other implementations, the beam measurements performed by the UE 102 are based on multiple samples (referred to hereinafter as multi-shot) . Multiple samples can be used in FR2 if a beam sweeping factor (N) is applicable. Multiple samples can be used if the parameter timeRestrictionForChannelMeasurement is not configured (M=3) . The beam measurement reporting delay is determined by the start time (e.g., when a trigger condition is met over-the-air) , the time at which the UE 102 triggers an event based on reference measurement (s) , and the time at which the UE 102 transmits the first PUCCH to request resources or notify the network.

The UE-initiated beam measurement scheme 200 of FIG. 2 is an example of a one-shot beam measurement scheme, where (i) the current beam and the new beam have the same reference signal periodicity and (ii) reference signals associated with the current beam and the new beam are located in different slots.

[0033] In accordance with aspects of the present disclosure, a UE (such as the UE 102 of FIG. 1) can determine a measurement period for UE-initiated beam measurement reporting delay estimation based on the reference signal periodicity of the current beam (TcurrBeam) , the reference signal periodicity of the new beam (TnewBeam) , the number of samples used for beam measurements (one-shot or multi-shot) , and whether reference signals associated with the current beam are adjacent to (or overlap with) reference signals associated with the new beam.
[0034] Ifthe current beam and the new beam have the same reference signal periodicity (TRS) , and single-shot measurement is configured, and reference signals for the two beams are located in different slots (as shown in FIG. 2) , the measurement period (e.g., the time between when a trigger condition occurs and when an event is triggered by the UE) can be determined according to max {Tfirst_newBeam, Tfirst_currBeam} , where Tfirst_newBeam is the time until the next reference signal associated with the new beam and Tfirst_currBeam is the time until the next reference signal associated with the current beam. Alternatively, the measurement period can be defined as the periodicity of the new beam and the current beam (TRS) .
[0035] Ifthe current beam and the new beam have the same reference signal periodicity (TRS) , and single-shot measurement is configured, in FR1 or in FR2 the two beams have non-overlapping / adjacent reference signals in the same slot, the measurement period can be defined as Tfirst_newBeam or Tfirst_currBeam. Alternatively, the measurement period can be defined as the periodicity of the new beam and the current beam (TRS) .
[0036] Ifthe current beam and the new beam have the same reference signal periodicity (TRS) , and single-shot measurement is configured, and the two beams have adjacent / overlapping reference signals in the same slot (as shown in FIG. 3) in FR2, the measurement period can be determined according to Tfirst_newBeam + TRS or rfirst_currBeam + TRS. Alternatively, the measurement period can be defined as twice the periodicity of the new beam and the current beam: 2*TRS.
[0037] If the reference signal periodicity of the current beam (TcurrBeam) is different from the reference signal periodicity of the new beam (TnewBeam) , and single-shot measurement is configured, and reference signals associated with the current beam and the new beam are located in different slots (as shown in FIG. 5) , the measurement period can be determined according to max {Tfirst_newBeam, Tfirst_currBeam} .

[0038] If the reference signal periodicity of the current beam (TcurrBeam) is different from the reference signal periodicity of the new beam (TnewBeam) , and single-shot measurement is configured, in FR1 or in FR2 reference signals associated with the two beams are within the same slot (but not adjacent or overlapping) , the measurement period can be determined according to max {Tfirst_newBeam, Tfirst_currBeam} . Alternatively, the measurement period can be determined according to max {TnewBeam, TcurrBeam} .
[0039] If the reference signal periodicity of the current beam (TcurrBeam) is different from the reference signal periodicity of the new beam (TnewBeam) , and single-shot measurement is configured, and reference signals associated with the two beams are adjacent or overlapping in at least one slot (as shown in FIG. 4) in FR2, the measurement period can be defined as Tfirst_newBeam or Tfirst_currBeam + min {TnewBeam, TcurrBeam} if Tfirst_newBeam = Tfirst_currBeam or max {Tfirst_newBeam, Tfirst_currBeam} otherwise. Alternatively, the measurement period can be defined as max {TnewBeam, TcurrBeam} .
[0040] Ifthe current beam and the new beam have the same reference signal periodicity (TRS) , and multi-shot measurement is configured, and reference signals for the two beams are located in different slots, the measurement period can be determined according to max {Tfirst_newBeam + (MN*NN-1) *TRS, Tfirst_currBeam + (MC*NC-1) *TRS} , where MC is the number of measurement samples for the current beam, MN is the number of measurement samples for the new beam, NC is a beam sweep factor applicable for the current beam, and NN is a beam sweep factor applicable for the new beam. Alternatively, the measurement period for the current beam and the new beam can be determined according to max {MN*NN*TRS, MC*NC*TRS} .
[0041] If the current beam and the new beam have the same reference signal periodicity (TRS) , and multi-shot measurement is configured, in FR1 or in FR2 the two beams have non-overlapping / adjacent reference signals in the same slot, the measurement period can be determined according to Tfirst_newBeam or Tfirst_currBeam + max { (MN*NN-1) *TRS, (MC*NC-1) *TRS} . Alternatively, the measurement period for the current beam and the new beam can be determined according to max {MN*NN*TRS, MC*NC*TRS} .
[0042] Ifthe current beam and the new beam have the same reference signal periodicity (TRS) , and multi-shot measurement is configured, and the two beams have adjacent / overlapping reference signals in the same slot in FR2, the measurement period can be determined according to max{Tfirst_newBeam + (2*MN*NN-1) *TRS , Tfirst_currBeam + (2*MC*NC-1) *TRS} . Alternatively, the measurement period can be defined as twice the measurement period of the new beam or the current beam: max {2*MN*NN*TRS, 2*MC*NC*TRS} .
[0043] Ifthe reference signal periodicity of the current beam (TcurrBeam) is different from the reference signal periodicity of the new beam (TnewBeam) , and multi-shot measurement is configured, and reference signals associated with the two beams are located in different slots, the measurement period can be determined according to max {Tfirst_newBeam + (MN*NN-1) *Tfirst_newBeam, Tfirst_currBeam + (MC*NC-1) *Tfirst_currBeam} . Alternatively, the measurement period can be determined according to max {MN*NN*TnewBeam, MC*NC*TcurrBeam} .
[0044] If the reference signal periodicity of the current beam (TcurrBeam) is different from the reference signal periodicity of the new beam (TnewBeam) , and multi-shot measurement is configured, in FR1 or in FR2 the reference signals associated with the current beam and the new beam are within the same slot (but not adjacent or overlapping) , the measurement period can be determined according to max {Tfirst_newBeam + (MN*NN-1) *TnewBeam, Tfirst_currBeam + (MC*NC-1) *TcurrBeam} . Alternatively, the measurement period can be determined according to max {MN*NN*TnewBeam, MC*NC*TcurrBeam} .
[0045] If the reference signal periodicity of the current beam (TcurrBeam) is different from the reference signal periodicity of the new beam (TnewBeam) , and multi-shot measurement is configured, and reference signals associated with the two beams are adjacent or overlapping in at least one slot in FR2, the measurement period can be determined according to the following criteria. If TnewBeam < TcurrBeam and Tfirst_newBeam = Tfirst_currBeam, the measurement period can be determined according to Tfirst_newBeam or Tfirst_currBeam + max { (MN*NN*PN-1) *TnewBeam, (MC*NC-1) *TcurrBeam} , where
[0046] If TnewBeam < TcurrBeam and Tfirst_newBeam < Tfirst_currBeam, the measurement period can be determined according to max {Tfirst_newBeam + (MN*NN*PN-1) *TnewBeam, Tfirst_currBeam + (MC*NC-1) *TcurrBeam} . If TcurrBeam < TnewBeam and Tfirst_newBeam = Tfirst_currBeam, the measurement period can be determined according to Tfirst_newBeam or Tfirst_currBeam + max { (MN*NN-1) *TnewBeam, (MC*NC*PC-1) *TcurrBeam} , where If TcurrBeam < TnewBeam and Tfirst_currBeam <Tfirst_newBeam, the measurement period can be determined according to max {Tfirst_newBeam + (MN*NN-1) *TnewBeam, Tfirst_currBeam + (MC*NC*PC-1 ) *TcurrBeam} . Alternatively, if TnewBeam <TcurrBeam, the measurement period can be determined according to max {MN*NN*PN*TnewBeam, MC*NC*TcurrBeam} . If TcurrBeam < TnewBeam, the measurement period can be determined according to max {MN*NN*TnewBeam, MC*NC*PC*TcurrBeam} .
[0047] Using the techniques and criteria discussed above, the UE can determine a measurement period for UE-initiated / event-driven beam measurement reporting delay estimation. This measurement period reflects the time taken for reference signal measurement (s) to trigger an event for single-shot measurement. At the UE, this event can be triggered after measuring the new beam (point A) or after measuring the current beam (point B) . Since the network may be unable to determine the measurement constraints for both scenarios, a worst-case delay scenario (where the event is triggered at the UE 102 after point B) is assumed. The measurement delay periods described herein are also applicable to L1 / L2-triggered inter-cell mobility, where measurements are performed on a serving cell (e.g., the current beam) and a neighbor cell (e.g., the new beam) , respectively.
[0048] If the new beam or current beam overlap with any measurement gap, SMTC occasion, or L1-RSRP measurement, a sharing factor may be considered and the measurement period can be increased accordingly. If the reference signal being measured is an SSB from a serving cell, the sharing factor P from Section 9.5.4.1 of 3GPP TS 38.133 can be used. If the reference signal being measured is an SSB from a cell with a different physical cell identifier (PCI) the sharing factor P from Section 9.13.4.1 of 3GPP TS 38.133 can be used. Otherwise, if the reference signal being measured is a CSI-RS, the sharing factor P from Section 9.5.4.2 of 3GPP TS 38.133 can be used.
[0049] In the foregoing description, the time to send PUCCH is the after measurement time to PUCCH occasion TfirstPUCCH or TPUCCH (e.g., the periodicity of PUCCH resources) , and the total measurement delay is determined as the measurement period + the time to send PUCCH. Table 1: Measurement Periodfor Same Reference Signal Periodicity
[0050] In Table 1, P1 is sharing factor configured for the new beam based on the type of reference signal being measured, and P2 is sharing factor configured for the current beam based on the type of reference signal being measured. Table 2: Measurement Period for Different Reference Signal Periodicities
[0051] In Table 2, P1 is a sharing factor configured for the new beam based on the type of reference signal being measured, P2 is a sharing factor configured for the current beam based on the type of reference signal being measured, and

For example, the method 600 can be performed by a UE (such as the UE 102 of FIG. 1) , or any suitable system, environment, software, hardware, or combination thereof.

[0056] FIG. 7 illustrates a flowchart of an example method 700, according to some implementations. For clarity of presentation, the method 700 is described in the context of the preceding figures. For example, the method 700 can be performed by a base station (such as the base station 104 of FIG. 1) , or any suitable system, environment, software, hardware, or combination thereof. In some implementations, operations of the method 700 can be run in parallel, in combination, in loops, or in any order. The example method 700 shown in FIG. 7 can be modified or reconfigured to include additional, fewer, or different steps (not shown in FIG. 7) , which can be performed in the order shown or in a different order.

[0162] Any of the foregoing examples can be combined with any other example (or combination of examples) , unless explicitly stated otherwise. The foregoing description of one or more implementations provides illustration and description, but is not intended to be exhaustive or to limit the scope of embodiments to the precise form disclosed. Modifications and variations are possible in light of the above teachings or may be acquired from practice of various embodiments.
[0163] Although the embodiments above have been described in considerable detail, numerous variations and modifications will become apparent to those skilled in the art once the above disclosure is fully appreciated. It is intended that the following claims be interpreted to embrace all such variations and modifications.
[0164] As described above, one aspect of the present technology may relate to the gathering and use of data available from specific and legitimate sources to allow for interaction with a second device for a data transfer. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to identify a specific person. Such personal information data can include demographic data, location-based data, online identifiers, telephone numbers, email addresses, home addresses, data or records relating to a user’s health or level of fitness (e.g., vital signs measurements, medication information, exercise information) , date of birth, or any other personal information.
[0165] The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to provide for secure data transfers occurring between a first device and a second device. The personal information data may further be utilized for identifying an account associated with the user from a service provider for completing a data transfer.
[0166] The present disclosure contemplates that those entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and / or privacy practices. In particular, such entities would be expected to implement and consistently apply privacy practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining the privacy of users. Such information regarding the use of personal data should be prominent and easily accessible by users, and should be updated as the collection and / or use of data changes. Personal information from users should be collected for legitimate uses only. Further, such collection / sharing should occur only after receiving the consent of the users or other legitimate basis specified in applicable law. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and / or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations that may serve to impose a higher standard. For example, in the US, collection of or access to certain health data may be governed by federal and / or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA) ; whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly.
[0167] Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and / or software elements can be provided to prevent or block access to such personal information data. For example, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. For example, a user may “opt in” or “opt out” of having information associated with an account of the user stored on a user device and / or shared by the user device. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For example, a user may be notified upon downloading an application that their personal information data will be accessed and then reminded again just before personal information data is accessed by the application. In some instances, the user may be notified upon initiation of a data transfer of the device accessing information associated with the account of the user and / or the sharing of information associated with the account of the user with another device.
[0168] Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user’s privacy. De-identification may be facilitated, when appropriate, by removing identifiers, controlling the amount or specificity of data stored (e.g., collecting location data at city level rather than at an address level) , controlling how data is stored (e.g., aggregating data across users) , and / or other methods such as differential privacy.
[0169] Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, content can be selected and delivered to users based on aggregated non-personal information data or a bare minimum amount of personal information, such as the content being handled only on the user’s device or other non-personal information available to the content delivery services.
