[0039] Figure 1 An example of a network 100 comprising multiple network entities is shown, including a terminal device 110, a node device 120, and one or more network devices 130. The terminal device 110 and the node device 120 communicate with each other 124. One or more network devices 130 communicate with the node device 120 128.

[0040] In some examples, one or more network devices 130 communicate with terminal device 110. In some examples, one or more network devices 130 may communicate with each other. In some examples, one or more node devices 120 may communicate with each other.

[0041] Network 100 can be a cellular network comprising multiple cells 122, each cell being served by node device 120. In this example, the interface between terminal device 110 and node device 120 defining cell 122 is wireless interface 124.

[0042] Node device 120 includes one or more cellular radio transceivers. Terminal device 110 includes one or more cellular radio transceivers.

[0043] In the example shown, cellular network 100 is a 3GPP network, where terminal device 110 is a user equipment (UE), and node device 120 can be an access node such as a base station.

[0044] A user equipment includes a mobile device. Reference to the user equipment may include and incorporate references to the mobile device, where possible.

[0045] In some examples, during operation, user equipment 110 includes a mobile device that includes a smart card, such as a subscriber identity module (SIM), for authentication / encryption, etc. In some examples, during operation, user equipment 110 includes a mobile device that includes circuitry for authentication / encryption, such as a software SIM, embedded as part of user equipment 110.

[0046] Node device 120 can be any suitable access node, such as a base station or transmit / receive point. Node device 120 can be a network element responsible for radio transmission and reception to or from UE 110 in one or more cells 122. Node device 120 can be a network element in a radio access network (RAN), an open radio access network (O-RAN), or any other suitable type of network.

[0047] Network device 130 can be part of the core network. Network device 130 can be configured to manage functions related to connectivity with multiple UEs 110. For example, network device 130 can be configured to manage functions such as connectivity, mobility, authentication, authorization, and / or other suitable functions. In some examples, network device 130 can include Access and Mobility Management Functions (AMF) and / or User Plane Functions (UPF) or any other suitable entity.

[0048] exist Figure 1 In the example, network device 130 is shown as a single entity. In some examples, network device 130 may be distributed across multiple entities. For example, network device 130 may be cloud-based or distributed in any other suitable manner. Network device 130 can be a core network node.

[0049] For example, network 100 can be a 4G or 5G network. For instance, it can be a New Radio (NR) network using gNBs or eNBs as access nodes 120. NR is a 3GPP name for 5G technology. In this case, node device 120 can include multiple gNodeBs (gNBs) 120 configured to provide user plane and control plane protocol termination and / or perform any other suitable functions to UE 110. Multiple gNBs 120 interconnect with each other via X2 / Xn interfaces 126. Multiple gNBs are also connected to network device 130 via N2 interfaces 128. Multiple gNBs can connect to an AMF or any other suitable network device 130. Other types of networks and interfaces can be used in other examples. Other types of networks can include next-generation mobile and communication networks, such as 6G networks.

[0050] Figure 2 An example of a device (e.g., user equipment 110) is shown, which includes components for the following operations: Execute Layer 1 (L1) measurement 202; Based on measurement 202, provide L1 measurement report 11. If the event-triggered measurement report is active, then the first L1 measurement report format 13_1 is used; and If the measurement report triggered by the event is not active, then the second L1 measurement report format 13_2 is used. The first L1 measurement report format 13_1 is configured to carry one or more indications to the triggered L1 measurement report event 205.

[0051] In at least some examples, user equipment 110 includes components for determining whether L1 measurement 202 triggers an L1 measurement report event 205 (referred to as triggered L1 measurement report event 205). User equipment 110 thus determines whether L1 measurement 202 results in triggered L1 measurement report event 205. If the result of L1 measurement 202 (or the results of multiple L1 measurements 202) satisfies the triggering condition of an L1 measurement report event, then L1 measurement 202 results in triggered L1 measurement report event 205. If measurement 202 satisfies the triggering condition of an L1 measurement report event, then the measurement report event is triggered, thereby resulting in triggered L1 measurement report event.

[0052] If L1 measurement 202 results in a triggered L1 measurement report event 205, then the first L1 measurement report format 13_1 is used for L1 measurement report 11. User equipment 110 sends L1 measurement report 11 to network 120 using the first L1 measurement report format 13_1.

[0053] User equipment 110 performs L1 measurement 202. L1 measurement 202 is a measurement at the physical (PHY) layer, which is the lowest layer of the protocol stack.

[0054] In some, but not all, examples, L1 measurement 202 measures the physical layer characteristics of downlink signal 203. In some, but not all, examples, downlink signal 203 is a reference signal.

[0055] Examples of physical layer characteristics include, but are not limited to, measurements of received signal strength or power.

[0056] Examples of physical layer characteristics include, but are not limited to, Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Received Signal Strength Indicator (RSSI).

[0057] In some, but not all, examples, downlink signal 203 is a beam (directional signal). In 3GPP, the Synchronization Block (SSB) can be used as a wide-beam reference signal, and the Channel State Information Reference Signal (CSI-RS) can be used as a narrow-beam reference signal. In some examples, the CSI-RS can be used together with the corresponding beam as an SSB signal.

[0058] User equipment 110 determines whether L1 measurement 202 triggers L1 measurement report event 205. User equipment 110 therefore determines whether L1 measurement 202 results in a triggered L1 measurement report event 205. If the result of L1 measurement 202 (or the result of L1 measurement 202) meets the triggering conditions for an L1 measurement report event, then L1 measurement 202 results in a triggered L1 measurement report event 205. If the L1 measurement meets the triggering conditions for an L1 measurement report event, then the L1 measurement report event is triggered, thereby resulting in triggered L1 measurement report event 205.

[0059] In at least some examples, the triggering condition is based on signal quality measurements.

[0060] In at least some examples, the triggering condition is based on a comparison of the received signal quality of reference signal 203 with a threshold (absolute or relative threshold). The relative threshold can be based on the received signal quality of another candidate reference signal 203. The received signal quality of reference signal 203 can be based on a single reference signal or a set of reference signals.

[0061] L1 measurement report 11 is configured with a first L1 measurement report format 13_1, which is configured to carry one or more indications / identifiers for a triggered L1 measurement report event 205. L1 measurement report 11 is sent to network 120.

[0062] In at least some examples, the first format 13_1 is configured to carry one or more indications that a report event has been triggered. In at least some examples, the second format 13_2 is configured not to carry one or more indications that a report event has been triggered.

[0063] In at least some examples, L1 measurement report 11 is sent via L1 resource 207.

[0064] Figure 3 It shows something similar to Figure 2 The example shown.

[0065] In this example, downlink configuration 220 is sent by network 120 to the user equipment to configure the user equipment.

[0066] The first L1 measurement report format 13_1 is configured to carry one or more identifiers 206 for the corresponding triggered L1 measurement report event 205.

[0067] The triggered L1 measurement report event 205 is used to obtain the associated identifier 206 of the triggered L1 measurement report event 205.

[0068] In this example, if the event-triggered measurement report is active, a layer 1 (L1) measurement 202 will be performed, and the stage marker of the L1 measurement report 11 will be provided in the first L1 measurement report format 13_1 based on the measurement 202, which is used for reporting (event-triggered).

[0069] In this example, if the event-triggered measurement report is inactive, a layer 1 (L1) measurement 202 will be performed, and the stage marker of the L1 measurement report 11, which is provided in the second L1 measurement report format 13_2 according to the measurement 202, will be RM, which is used for reporting (measurement).

[0070] In at least some examples, the first format 13_1 of the L1 measurement report 11 includes the identifier 206 of the triggered L1 measurement report event 205.

[0071] In at least some examples, the second format 13_2 of the L1 measurement report 11 does not include the identifier of the triggered L1 measurement report event 205.

[0072] In at least some examples, the identifier 206 of the triggered L1 measurement report event 205 is pre-configured by the network, for example via downlink configuration 220.

[0073] In at least some examples, the identifier 206 of the triggered L1 measurement report event 205 and the L1 resource 207 for sending the first format measurement report 11 are pre-configured by the network.

[0074] In at least some examples, the L1 measurement report 11 is transmitted as uplink control information (UCI) with different formats 13_1 and 13_2. Different formats 13_1 and 13_2 can be configured via downlink configuration 220.

[0075] In some, but not all, examples, the first format 13_1 of the L1 measurement report 11 is configured to carry an indication / identifier of multiple (or one or more) reporting events that have been triggered.

[0076] In some, but not all, examples, the first format 13_1 of the L1 measurement report 11 is configured to carry indications / identifiers of multiple reporting events that have been or have not yet been triggered.

[0077] In some examples, identifier 206 in the first format 13_1 of L1 measurement report 11 is a bitmap that includes a series of multiple independent bits, where each independent bit is mapped to a measurement report event, and the value of the bit indicates the triggering state of the measurement report event.

[0078] In some examples, identifier 206 in the first format 13_1 of measurement report 11 is a code point that includes a combination of bits that is mapped as a combination to the measurement report event result.

[0079] In at least some examples, the L1 measurement report 11 is sent via L1 resources 207 configured by the network, such as via downlink configuration 220.

[0080] In at least some examples, the same L1 resource 207 is configured for both the first format L1 measurement report 11 and the second format L1 measurement report 11.

[0081] In at least some examples, L1 resource 207 is a periodic resource. In some examples, this periodic resource is configured by downlink configuration 220.

[0082] In at least some examples, L1 resource 207 is a physical uplink channel resource. For example, the physical uplink channel resource used for L1 resource 207 can be periodic or semi-persistent.

[0083] In some examples, L1 resource 207 is either the Physical Uplink Shared Channel Resource (PUSCH) or the Physical Uplink Common Channel Resource (PUCCH).

[0084] In some examples, there are multiple periodic resources that can be used as L1 resources 207 for L1 measurement report 11, and the periodic resource for L1 resource 207 for L1 measurement report 11 is the periodic resource with the shortest period selected from multiple available periodic resources. For example, the L1 resource 207 with the shortest period is used to send L1 measurement report 11 in the first format 13_1.

[0085] In at least some examples, L1 resource 207 includes at least one time- and / or frequency-restricted resource, such as at least one physical resource block (PRB).

[0086] In some examples, L1 measurement reports 11 are sent by user equipment 110 in uplink control information (UCI).

[0087] In some examples, the L1 resource 207 used for L1 measurement report 11 is a resource configured for beam management or a resource configured for lower-layer triggered mobility (LTM). This configuration can be, for example, via downlink configuration 220.

[0088] In some examples, the second format L1 measurement report 11 is configured for beam management or lower-layer triggered mobility (LTM). In at least some examples, the first format 13_1 for L1 measurement report 11 and the second format 13_2 for L1 measurement report [for beam management or lower-layer triggered mobility (LTM)] are configured simultaneously, for example, via downlink configuration 220.

[0089] In some examples, L1 measurement report 11 is a channel state information (CSI) configuration report, such as a CSI report.

[0090] In some examples, the formats 13_1 and 13_2 of the L1 Measurement Report 11 define the fields or field order in the L1 Measurement Report 11.

[0091] In some examples, the first format 13_1 of the L1 measurement report 11 is defined via fields of CSI-ReportConfig or LTM-CSI-ReportConfig.

[0092] In some examples, the first format 13_1 of the L1 measurement report 11 is defined via the CapabilityIndex field of CSI-ReportConfig. In some examples, the CapabilityIndex field of CSI-ReportConfig includes one or more additional fields for defining the first format, compared to the CapabilityIndex field of CSI-ReportConfig which is only used to define the second format 13_2.

[0093] In some examples, the first format 13_1 of the L1 measurement report 11 is defined as being reported as part of another report configuration that uses the first report format, such as as part of the CapabilityIndex field of CSI-ReportConfig.

[0094] In the foregoing example, the operation has been explained with reference to a triggered L1 measurement report event 205 and an identifier 206 of the triggered L1 measurement report event 205 sent via L1 resource 207 using the first format 13_1 of L1 measurement report 11.

[0095] However, in some and other examples of these examples, there exists a set of possible triggered L1 measurement report events 205. In some of these examples, multiple measurement report events are triggered. Identifiers 206 of multiple triggered L1 measurement report events 205 can be sent via L1 resource 207 using the first format 13_1 of L1 measurement report 11.

[0096] In some examples, user equipment 110 includes components for receiving downlink configuration 220 from network 120 for a plurality of triggered measurement report events 205, the downlink configuration 220 including an identifier 206 of the corresponding triggered measurement report event 205, and including components for transmitting the identifier 206 of the triggered L1 measurement report event 205 via L1 resource 207 using a first format 13_1 of L1 measurement report 11, based on the triggering of at least one of the plurality of configured measurement report events.

[0097] In some examples, the sent identifier 206 identifies multiple triggered L1 measurement report events 205.

[0098] In some examples, identifier 206 is a bitmap comprising a series of multiple independent bits, where each independent bit maps to a measurement reporting event, and the value of that bit indicates the triggering state of the measurement reporting event. The triggering state can be triggered or not triggered.

[0099] In some examples, identifier 206 is a code point comprising a combination of bits that is mapped as a combination to a measurement report event result. The result can be that a particular measurement report event has been / has not been triggered. The result can include, for example, no event being triggered, one of multiple events being triggered, or one of multiple configurations of multiple triggered events.

[0100] In this example, if the event-triggered measurement report is active, a layer 1 (L1) measurement 202 is performed, and the stage that provides an L1 measurement report 11 based on the first L1 measurement report format 13_1 according to the measurement 202 is marked as RET[2], which is used for the event-triggered two-stage report.

[0101] Figure 4 An example of a device 110 (e.g., user equipment 110) is shown, which includes components for the following operations: Execute Layer 1 (L1) measurement 202; Determine whether measurement 204 L1 triggers measurement report event 205; An L1 measurement report 11 is sent via L1 resource 207 in a first format 13_1, the L1 measurement report 11 including an identifier 206 of a triggered L1 measurement report event 205; and An event-triggered measurement report 210 is sent via uplink resource 209, the measurement report 210 being for the triggered L1 measurement report event 205.

[0102] In at least some examples, uplink resource 209 is configured by the network.

[0103] In at least some examples, uplink resource 209 is pre-configured by the network before the identifier 206 of the triggered L1 measurement report event 205 is sent via L1 resource 207. In at least some examples, uplink resource 209 is post-configured (dynamically configured) by the network after the identifier 206 of the triggered L1 measurement report event 205 is sent via L1 resource 207.

[0104] In some examples, the triggered L1 measurement reporting event 205 is used to acquire uplink resource 209. In some examples, the acquired uplink resource 209 is pre-configured. In other examples, the acquired uplink resource 209 is dynamically configured.

[0105] Figure 4 An example of network configuration is shown. In this example, base station 120 sends configuration message 220 or multiple configuration messages 220. In at least some examples, configuration message 220 is a radio resource control configuration message or a reconfiguration message.

[0106] In this example and other examples, the network sends configuration message 220 before sending identifier 206 of L1 measurement report 11. In this example, the network also sends configuration message 220 after sending L1 measurement report 11.

[0107] In this example and others, network configuration message 220 configures L1 measurement 202.

[0108] In this example and others, network configuration message 220 configures triggering conditions for the triggered L1 measurement report event 205.

[0109] In this example and others, the network configuration message 220 is the configuration identifier 206 for the triggered L1 measurement report event 205.

[0110] In this and other examples, network configuration message 220 at least partially configures L1 resource 207 for transmitting identifier 206. In at least some examples, network configuration message 220 configures physical channels for transmitting indicator 206. In at least some examples, network configuration message 220 configuration is shared and used for resources of L1 resource 207 and uplink resource 209. In at least some examples, network configuration message 220 configuration includes resources for a series of periodic reporting opportunities for transmitting indicator 206. In at least some examples, network configuration message 220 configures one or more specific periodic reporting opportunities for different triggered L1 measurement reporting events 205 to transmit indicator 206 for that triggered L1 measurement reporting event 205.

[0111] In some, but not all, examples, network configuration message 220 at least partially configures uplink resource 209 for sending event-triggered measurement reports 210. In at least some examples, network configuration message 220 configures physical channels for sending event-triggered measurement reports 210. In at least some examples, network configuration message 220 configures resources shared and used for L1 resource 207 and uplink resource 209. In at least some examples, network configuration message 220 configures resources including a series of periodic reporting opportunities for sending event-triggered measurement reports 210. In at least some examples, network configuration message 220 configures one or more specific periodic reporting opportunities for different triggered L1 measurement report events 205 to send indications of triggered L1 measurement report events 205.

[0112] The network configuration messages 220 can be implemented, for example, using one or more configuration messages 220. These messages may include, for example, event configuration, periodic PUCCH configuration, resource configuration, and report configuration.

[0113] In at least some examples, uplink resource 209 is pre-configured by configuration message 220 for use in triggered L1 measurement report event 205.

[0114] In some examples, the uplink resource 209 for the triggered L1 measurement report event 205 is a shared resource for both the uplink resource 209 for the triggered L1 measurement report event 205 and the L1 resource 207 for sending the identifier 206 of the triggered L1 measurement report event 205. In at least some examples, both the uplink resource 209 for the triggered L1 measurement report event 205 and the L1 resource 207 for sending the identifier 206 of the triggered L1 measurement report event 205 are configured as shared resources by configuration message 220.

[0115] In some examples, the shared resource is the physical uplink channel, such as the physical uplink control channel (PUCCH) or the physical uplink shared channel (PUSCH).

[0116] In some examples, the uplink resource 209 for the triggered L1 measurement reporting event 205 is a periodic resource used for the uplink resource 209 for that triggered L1 measurement reporting event 205. In at least some examples, a specific reporting timing (RO) 209 is used for a specific triggered L1 measurement reporting event 205—the reporting timing (RO) 209 depends on the triggered L1 measurement reporting event 205. In some examples, the uplink resource 209 for the triggered L1 measurement reporting event 205 is configured by configuration message 220.

[0117] In some examples, the periodic resource is a physical uplink channel, such as the Physical Uplink Control Channel (PUCCH) or the Physical Uplink Shared Channel (PUSCH). In some examples, this periodic resource is configured by downlink configuration message 220. In some examples, in response to the sending of identifier 206 of triggered L1 measurement report event 205, uplink resources 209 for triggered L1 measurement report event 205 are dynamically configured (scheduled) after measurement 202.

[0118] In at least some examples, uplink resource 209 is configured for triggered L1 measurement report event 205 via configuration message 220, such as downlink control information (DCI), sent by the network in response to identifier 206 of sending triggered L1 measurement report event 205.

[0119] In at least some examples, the configuration message 220 for dynamic configuration includes the previously received identifier 206.

[0120] Uplink resource 209 can be, for example, a physical uplink channel, such as a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH). Uplink resource 209 can be used, for example, to transmit media access control (MAC) control elements (CE) or L1 reports (PUCCH reports or PUSCH reports).

[0121] In some examples, user equipment 110 has components for sending an event-triggered measurement report 210 via uplink resource 209, the measurement report 210 being for a triggered L1 measurement report event 205, wherein a pre-configured uplink resource associated with the triggered L1 measurement report event 205 is used, or Uplink resources are dynamically configured (e.g., scheduled) by the network.

[0122] In some examples, user equipment 110 has a pre-configured uplink resource 209 for determining whether a measurement report 210 triggered by an event associated with a triggered L1 measurement report event 205 is sent via a component that is scheduled by the network based on the triggered L1 measurement report event 205.

[0123] In some examples, user equipment 110 can provide an indication via L1 measurement report 11, which includes an identifier 206 sent to the network indicating the need for dynamic configuration of uplink resources 209.

[0124] In other examples, user equipment 110 and the network share the same rules used to determine whether to use pre-configured uplink resource 209 or dynamically configured uplink resource 209. Therefore, user equipment 110 knows it should expect to receive configuration message 220 for dynamically configured uplink resource 209, and network 120 knows to send configuration message 220 for dynamically configured uplink resource 209.

[0125] User equipment 110 can determine uplink resources 209 for sending an event-triggered measurement report 210 for the triggered L1 measurement report event 205 based on the triggered L1 measurement report event 205.

[0126] Network 120 can determine the uplink resource 209 for sending the event-triggered measurement report 210 for the triggered L1 measurement report 205 based on the triggered L1 measurement report event 205 identified by identifier 206.

[0127] Figures 5 to 7 A method that can be performed by user equipment 110 is shown.

[0128] In at least some examples, user equipment 110 includes components for switching the format of L1 measurement report 11 between a first L1 measurement report format 13_1 and a second L1 measurement report format 13_2. This switching can, for example, trigger a triggered L1 measurement report event 205 in response to determining an L1 measurement 202.

[0129] In at least some examples, the device 110 includes a component for switching the format of the L1 measurement report 11 from a second L1 measurement report format 13_2 to a first L1 measurement report format 13_1 in response to determining that the current L1 measurement 202 has caused a triggered L1 measurement report event 205.

[0130] Figure 5 An example method is shown. At box 300, it is determined whether L1 measurement 202 triggers an L1 measurement report event (the L1 measurement report event that caused the triggering). If L1 measurement 202 causes a triggered L1 measurement report event 205, the method moves to box 302, where an L1 measurement report 11 is prepared and sent in the first format 13_1.

[0131] If L1 measurement 202 does not result in a triggered L1 measurement report event 205, the method moves to box 304, where L1 measurement report 11 is prepared and sent in the second format 13_2.

[0132] In some examples, L1 measurement 202 does not cause / trigger the triggered L1 measurement reporting event 205 because event-triggered reporting is not enabled. The example pseudocode for this method is: If the event trigger indicator is activated Use the first (new) format 13_1 otherwise Use the second (traditional) format 13_2 End if The first (new) format can, for example, include an identifier 206 for the triggered L1 measurement report event 205.

[0133] Figure 6 An example method is shown. It is Figure 5 An example of the method shown.

[0134] At box 300, determine whether the L1 measurement triggers the L1 measurement report event (resulting in the triggered L1 measurement report event 205).

[0135] If the L1 measurement report event is not the triggered L1 measurement report event 205, the method moves to box 304, where the L1 measurement report 11 is prepared and sent in the second format 13_2 using the shared L1 resource 207.

[0136] If the L1 measurement report event is the triggered L1 measurement report event 205, then the method moves to box 310.

[0137] At box 310, determine whether the L1 measurement report 11 of the first format 13_1 can use the shared L1 resource 207.

[0138] In some examples, if the shared L1 resource 207 has sufficiently low latency (e.g., periodicity below a threshold), the L1 measurement report 11 of the first format 13_1 uses the shared L1 resource 207.

[0139] If the L1 measurement report 11 in the first format 13_1 can use the shared L1 resource 207, the method moves to box 302, where the L1 measurement report 11 is prepared and sent in the first format 13_1 using the shared L1 resource 207.

[0140] If the L1 measurement report 11 of the first format 13_1 cannot use the shared L1 resource 207, the method moves to box 312, and then prepares the L1 measurement report 11 and sends it using resources other than the shared L1 resource 207.

[0141] L1 measurement report 11 may optionally be prepared and sent in first format 13_1.

[0142] Other resources can be, for example, pre-scheduled, scheduled, periodic, or dynamically scheduled.

[0143] The example pseudocode for this method is: If the event trigger indicator is activated If the usage criteria are met: Use the first (new) format Use periodic reports [shared resources] otherwise Use other resources Optionally, use the first (new) format. End if otherwise Use the second (traditional) format Use periodic reports [shared resources] End if Figure 7 An example method is shown. It is Figure 5 Examples of the methods shown are illustrated. Although they are shown separately... Figure 6 and Figure 7 There are several methods, but they can be combined.

[0144] At box 320, determine whether an L1 measurement has occurred.

[0145] If the L1 measurement has not yet occurred, the method moves to box 304, where an L1 measurement report 11 is prepared and sent in the second format 13_2 using shared L1 resource 207.

[0146] If an L1 measurement has already occurred, the method moves to box 300.

[0147] At box 300, determine whether the L1 measurement triggers the L1 measurement report event (resulting in the triggered L1 measurement report event 205).

[0148] If the L1 measurement does not result in a triggered L1 measurement report event 205, the method moves to box 322, where an L1 measurement report 11 is prepared and sent using shared L1 resources 207 in a first format 13_2. The L1 measurement report 11 in the first format 13_2 includes an indication that a triggered L1 measurement report event 205 does not exist.

[0149] If an L1 measurement results in a triggered L1 measurement report event 205, the method moves to box 302, where an L1 measurement report 11 is prepared and sent using shared L1 resource 207 in a first format 13_2. The L1 measurement report 11 in the first format 13_2 includes an indication of the presence of a triggered L1 measurement report event 205. It may, for example, include identifiers of one or more triggered L1 measurement report events 205.

[0150] The example pseudocode for this method is: If the event If the event trigger indicator is activated Use the first (new) format Use periodic reports [shared resources] Use the identifier that triggered the event. otherwise Use the first (new) format Use periodic reports [shared resources] Use identifiers that do not trigger events. End if otherwise Use the second (traditional) format Use periodic reports [shared resources] End if In some of the previously described examples, the user equipment is configured to retain shared L1 resources 207 when used for the first format measurement report 11.

[0151] Figure 8 It shows Figure 7 An example of the method shown. Already referenced. Figure 2 , 3 Described Figure 8The initial stage (RM). (Already referenced) Figure 4 Described Figure 8 The final stage (RET[2]).

[0152] exist Figure 8 In the intermediate stage (RnullT), if the L1 measurement does not result in a triggered L1 measurement report event 205, an L1 measurement report 11 is prepared and sent using shared L1 resources 207 in a first format 13_2. The L1 measurement report 11 in the first format 13_2 includes an indication that the triggered L1 measurement report event 205 does not exist.

[0153] Based on the foregoing, base station 120 includes components for configuring user equipment to operate as follows: Perform Layer 1 (L1) measurements; Provide an L1 measurement report based on the measurements. If the event-triggered measurement report is active, the first L1 measurement report format is used. If the event-triggered measurement report is not active, the second L1 measurement report format is used.

[0154] The first L1 measurement report format is configured to carry one or more indications to a triggered L1 measurement report event 205 for receiving L1 measurement reports and processing L1 measurement reports according to their format, wherein one or more indications to the triggered L1 measurement report event 205 are extracted from the first L1 measurement report format.

[0155] In at least some examples, the base station apparatus 120 includes components for: configuring periodic uplink resources for L1 resources used to transmit L1 measurement reports; and receiving L1 measurement reports via the configured periodic uplink resources.

[0156] In at least some examples, the base station device is configured to: if the L1 measurement report adopts a first L1 measurement report format, prepare to receive a transmitted event-triggered measurement report for a triggered L1 measurement report event 205 indicated by the first L1 measurement report format.

[0157] In at least some examples, the base station apparatus 120 includes a component for configuring an identifier for a triggered L1 measurement report event 205 to be used in the first L1 measurement report format.

[0158] In at least some examples, the base station apparatus 120 includes components for configuring shared resources for L1 measurement reports, the shared resources being used to transmit L1 measurement reports in a first L1 measurement report format and a second L1 measurement report format.

[0159] In at least some examples, the identifier associated with the event-based report included in the first format 13_1 may refer to an event identifier configured as part of the report configuration for the event-triggered report.

[0160] In at least some examples, the identifier associated with the event-based report included in the first format 13_1 may refer to a configured report identifier configured as part of the report configuration for the event-triggered report.

[0161] In at least some examples, the identifier associated with the event-based report included in the first format 13_1 may refer to an identifier configured as part of the report configuration for the event-triggered report.

[0162] In at least some examples, the identifier associated with the event-based report included in the first format 13_1 may refer to an identifier configured as part of the report configuration of the event-triggered report (where the event-triggered report may use a non-periodic report configuration).

[0163] Event-triggered Layer 1 measurements can be used, for example, in 3GPP for Layer-Triggered Mobility (LTM) (also known as L1 / L2-triggered mobility) as well as MIMO and event-driven beam management.

[0164] 3GPP has defined L1 reports for LTM as part of the CSI reporting framework (38.214, V18.1.0): Each report setting CSI-ReportConfig is associated with a single downlink BWP (indicated by the higher-layer parameter BWP-Id) for channel measurements given in the associated CSI-ResourceConfig, and contains (multiple) parameters for a CSI reporting band: codebook configuration (including codebook subset restrictions), time-domain behavior, frequency granularity of CQI and PMI, measurement restriction configuration, and CSI-related quantities reported by the UE, such as layer indicator (LI), L1-RSRP, L1-SINR, CRI, SSBRI (SSB resource indicator), CapabilityIndex, and TDCP.

[0165] Each report setting [LTM-CSI-ReportConfig] is associated with [LTM-CSI-ResourceConfig] for channel measurements and includes (multiple) parameters for time-domain behavior, the number of cells and the number of reference signals for each cell provided by [noOfReportedCells] and [noOfReportedRSPerCell] respectively, and includes L1 measurements associated with the current SpCell via SpCellInclusion.

[0166] The time-domain behavior of CSI-ReportConfig is indicated by the higher-level parameter reportConfigType, and can be set to "aperiodic", "semiPersistentOnPUCCH", "semiPersistentOnPUSCH", or "periodic". For "periodic" and "semiPersistentOnPUCCH" / "semiPersistentOnPUSCH" CSI reports, the configured periodicity and slot offset apply to the set of parameters in which the CSI report is configured to be sent by the UL BWP.

[0167] The higher-level parameter `reportQuantity` indicates the CSI-related quantity, L1-RSRP-related quantity, L1-SINR-related quantity, CapabilityIndex-related quantity, or TDCP-related quantity to be reported. `reportFreqConfiguration` indicates the reporting granularity in the frequency domain, including the CSI reporting band and whether the PMI / CQI report is wideband or subband. The `timeRestrictionForChannelMeasurements` parameter in `CSI-ReportConfig` can be configured to enable time-domain restriction for channel measurements, and `timeRestrictionForInterferenceMeasurements` can be configured to enable time-domain restriction for interference measurements.

[0168] The temporal behavior of [LTM-CSI-ReportConfig] is indicated by the higher-level parameter [reportConfigType], and can be set to "Aperiodic", "Semi-persistent on PUCCH", "Semi-persistent on PUSCH", or "Periodic". For "Periodic" and "Semi-persistent on PUCCH" / "Semi-persistent on PUSCH" CSI reports, the configured periodicity and slot offset are applied to the set of parameters in which the CSI report is configured to be sent by the UL BWP.

[0169] Each CSI resource setting, CSI-ResourceConfig, contains a configuration of a list of S ≥ 1 CSI resource sets (given by the high-level parameter csi-RS-ResourceSetList), where the list includes references to any one or both of the NZP CSI-RS resource sets and the SS / PBCH block sets, or the list includes references to the CSI-IM resource sets. Each CSI resource setting resides in a DL BWP identified by the high-level parameter BWP-id, and all CSI resource settings linked to the CSI reporting setting have the same DL BWP.

[0170] Each LTM CSI resource setting [LTM-CSI-ResourceConfig] contains the configuration of [LTM-CSI-SSB-ResourceSet], which includes a list of Z ≥ 1 SS / PBCH block indices (given by [LTM-csi-SSB-ResourceList]) and a list of Z [PCI indices] referring to the cells associated with the SS / PBCH block indices (given by [LTM-CandidateId-list]). The UE determines the temporal behavior of the SS / PBCH block based on ssb-Periodicity and ssb-PositionsInBurst, and the frequency domain behavior of the SS / PBCH block is determined by the higher-layer parameters subcarrierspacing and ssbFrequency.

[0171] Event-triggered L1 reports can be used for beam management / MIMO and / or LTM.

[0172] In one scenario, event trigger reports can be provided in two parts: - First, a (periodic) low-overhead signal can be configured to be associated with an event-based reporting configuration to indicate that a reporting event has been triggered. - Secondly, when the UE indicates that a reporting event has been triggered, it can use the associated resources to send the event-triggered report.

[0173] In scenarios where the UE can be configured to perform periodic L1 reporting (e.g., for beam management), configuring additional periodic signals or channels to indicate that an event-based report (e.g., for LTM) has been triggered at the UE may not be feasible. This could be a waste of UL resources.

[0174] In this disclosure, we propose that, depending on whether the UE is configured with at least one event-based reporting, the UE may conditionally apply or be configured with one or more L1 reporting formats for periodic L1 (i.e., the reporting format defines the mapping order of the CSI fields of the report content). - If no event-based reporting configuration is configured or activated, the UE can be configured to perform uplink periodic reporting using the second (traditional) L1 reporting format.

[0175] - When the event-based reporting configuration is configured or activated, the UE can be configured to perform uplink periodic reporting using the first (enhanced) L1 reporting format.

[0176] The first (enhanced) L1 format can carry one or more indications that a report event has been triggered.

[0177] In one embodiment, when the UE is configured with or has activated at least one event-based reporting configuration, the UE can be configured to report periodic or semi-persistent L1 CSI information using a first reporting format.

[0178] In one embodiment, the use of the first report format may be conditional on, or configured for, specific event-based reporting configurations: As an example, an event-triggered reporting configuration may include a configuration indicating whether an event is configured to be reported as part of another reporting configuration (using a first reporting format). The event is reported within another report (a separate configuration). The event indication (for event-triggered reporting) is signaled as part of the other reporting configuration (i.e., in this case, using the first enhanced format).

[0179] In one embodiment, the L1 reporting configuration may include an indication of whether the reporting configuration will be used for reporting using both the second and first reporting formats.

[0180] In one embodiment, the UE can be configured to switch from one reporting format to another based on the activation status of event-based reports. For example, if all configured event-based reports are deactivated, the UE can switch from a first reporting format to a second reporting format.

[0181] In one embodiment, the first reporting format may be conditional on a periodicity value configured for a periodic or semi-persistent reporting configuration. If the periodicity of the reporting configuration is less than a configured / specified threshold, the first reporting format is used to execute the report.

[0182] In one embodiment, if the first reporting format is activated / used, any resources configured for indications associated with event-based reporting (e.g., periodic uplink resources) are considered inactive or unusable by the UE.

[0183] "Any configured resource" is a different resource from periodic resources, and is not used if periodic resources are used. Conversely, it is used if periodic resources are not used. Therefore, if the UE is configured with a UL indicator (used to indicate a specific event and that the UE will use the associated UL resource for reporting), the UE does not use the UL indicator because the second reporting format in the periodic resource is active. Conversely, it uses the UL indicator if periodic resources are not used.

[0184] In one embodiment, if the UE is configured with multiple periodic reporting formats that can provide a first reporting format, the UE uses the first reporting format and the reporting configuration associated with the shortest periodicity and / or the lowest periodic reporting ID.

[0185] An example of an L1 report first format carrying instructions for event-based reporting, such as an event identifier, which may refer to an identifier associated with an event-based report: Table 1: Bit widths of CRI, SSBRI, RSRP, CapabilityIndex, and identifiers associated with event-based reporting

[0186] N can be determined by network configuration and / or by the UE. In one example, N can be determined based on the number of reporting configurations configured for event-based reporting.

[0187] Table 2. CSI field mapping order for a report using CRI / RSRP or SSBRI / RSRP or CRI / RSRP / CapabilityIndex or SSBRI / RSRP / CapabilityIndex reports, or CSI field mapping order for a report using inter-cell SSBRI / RSRP reports or event identifiers.

[0188] In one embodiment, if the UE is configured to report using a first reporting format and no event is triggered to report in the report, the UE can be configured to send a specific value to indicate that no event has been triggered.

[0189] Figure 8 An example signaling flow is shown in the figure.

[0190] Initial downlink configuration 220 configures the downlink radio resource control message for periodic CSI reporting.

[0191] In the RM phase, the L1 measurement report 11 adopts the second format 13_2. It is a periodic CSI report using the traditional format.

[0192] The next downlink configuration 220 is the activation of a downlink radio resource control message or a media access control (MAC_) control element (CE) whose configuration event triggers a report.

[0193] In phase RnullT, the L1 measurement report 11 adopts the first format 13_1. It has a null value for identifier 206. It is a periodic CSI report in the new format. The L1 measurement report 11 with a null value for identifier 206 indicates that no event has been triggered.

[0194] In phase RET[2], a reporting event is triggered 204. The L1 measurement report 11 adopts the first format 13_1. It has a value of identifier 206 that identifies the triggered measurement reporting event 205. It is a periodic CSI report in the new format. The value of identifier 206 in the L1 measurement report 11 indicates the event that has been triggered.

[0195] Event-triggered measurement report 210 can be sent to the same or different resources as L1 measurement report 11.

[0196] Event-triggered measurement reports 210 can be sent on pre-configured UL resources (such as periodic resources).

[0197] Event-triggered measurement reports 210 can be sent on dynamically configured UL resources.

[0198] In this example, the event-triggered measurement report 210 is sent on a dynamically configured UL resource. Network 120 schedules UL resource 209 for sending the event-triggered measurement report 210, or activates an existing configuration of UL resource 209 for sending the event-triggered measurement report 210.

[0199] Dynamic configuration can be performed via downlink control information (DCI) (e.g., aperiodic / UL authorization) or MAC CE (semi-persistent) or dynamic scheduling.

[0200] In one example (non-limiting), the events for which event-triggered reporting can be configured can be based on signal quality measurements: a) The measurement quality (e.g., RSRP / SINR) of a reference signal (or one or more reference signals) is worse than the configured threshold.

[0201] b) The measurement quality (e.g., RSRP / SINR) of at least one reference signal becomes / becomes a threshold (e.g., offset) value that is better than that of a particular reference signal (e.g., a reference signal corresponding to the PDCCH).

[0202] c) The offset can be configurable (e.g., -3dB, 0, 3dB) and the measurement quality (e.g., RSRP / SINR) of at least one reference signal is better than the configured threshold.

[0203] d) The measurement quality (e.g., RSRP / SINR) of at least one reference signal is worse than threshold 1, and the measurement quality (e.g., RSRP / SINR) of at least one other reference signal is better than threshold 2.

[0205] Based on the L1 measurement report configuration and the status of the L1 measurement report triggered by the event, information is sent using the first L1 measurement report format.

[0206] Obtain an L1 measurement report configuration for configuring the transmission of information associated with an event-triggered L1 measurement report, wherein the L1 measurement report configuration includes a first L1 measurement report format and the first L1 measurement report format is associated with an event-triggered L1 measurement report.

[0207] Based on the L1 measurement report configuration and the status of the L1 measurement report triggered by the event, information is sent using the first L1 measurement report format.

[0208] The characteristics of base station 120 include: Send an L1 measurement report configuration to the UE. This configuration is used to configure the transmission of information associated with an event-triggered L1 measurement report. The L1 measurement report configuration includes at least a first L1 measurement report format and a second L1 measurement report format, and the first L1 measurement report format is associated with the event-triggered L1 measurement report.

[0209] Based on the L1 measurement report configuration and the status of the L1 measurement report triggered by the event, information is received from the UE using the first L1 measurement report format.

[0210] Based on the received information, schedule information for sending L1 measurement reports for event triggering is sent to the UE. In some examples, a specific first L1 measurement report format (the UCI format for CSI only) is defined to send an indication that indicates an identifier associated with an event triggered by an event-triggered L1 measurement report.

[0211] The UE uses a specific UCI format to indicate triggered events and sends L1 measurement reports of triggered events based on scheduling information from the gNB.

[0212] Additional features include: When configuring or activating at least one event for L1 measurement reporting to be triggered for the UE, the UE uses a first L1 measurement report format to send information.

[0213] When the UE configures or activates an event for triggering an L1 measurement report, the UE uses a first L1 measurement report format to send information, wherein the UE is configured to use the first L1 measurement report format to send an indication for the event.

[0214] L1 measurement includes resource configuration for L1 measurement reporting, and the L1 measurement report configuration includes indications of whether the resource configuration is applied to both the first and second report formats.

[0215] When no L1 measurement report is configured for event triggering for the UE or the report is deactivated, the UE applies the second L1 measurement report format (traditional CSI report).

[0216] When the periodicity of resource allocation is less than the configured / specified threshold, the UE sends information using the first L1 measurement report format.

[0217] The resource configuration includes more than one periodic resource. The UE uses the first L1 measurement report format and the periodic resource with the shortest periodicity and / or lowest report ID to send information. The first L1 measurement report format includes an indication that indicates at least one identifier associated with at least one event used for triggering an L1 measurement report.

[0218] The UE may use a first L1 measurement report format to send information, wherein the information may include an indication that indicates one or more identifiers associated with one or more events triggered by an event-triggered L1 measurement report.

[0219] The UE may send information using a first L1 measurement report format, wherein the information may include an indication that no L1 measurement report for an event triggering the event has been generated.

[0220] After sending information, the UE receives scheduling information for sending L1 measurement reports triggered by events. The UE sends an L1 measurement report for event triggering based on scheduling information.

[0221] The proposed solution enhances the current UCI format (CSI only) to support event-triggered L1 measurement reports; by indicating the triggered event, the NW can more efficiently allocate UL resources to the UE to send L1 measurement reports triggered by the event.

[0222] Figure 10 A shows an example of method 500.

[0229] Figure 11 An example of a controller 400 suitable for use in a device (e.g., user equipment 110 or base station 120) is shown. The controller 400 can be implemented as a controller circuit. The controller 400 can be implemented solely in hardware, have certain aspects only in software including firmware, or can be a combination of hardware and software (including firmware).

[0230] like Figure 11 As shown, the controller 400 can be implemented using instructions that implement hardware functions, for example, by using executable instructions 406 in a general-purpose or special-purpose processor 402, which can be stored on a machine-readable storage medium (disk, memory, etc.) for execution by such processor 402.

[0231] Processor 402 is configured to read from and write to memory 404. Processor 402 may also include an output interface and an input interface, through which processor 402 outputs data and / or commands and through which data and / or commands are input to processor 402.

[0232] Memory 404 stores instructions, programs, or code 406 that control the operation of the device when loaded into processor 402. Computer program instructions, programs, or code 406 provide logic and routines that enable the device to perform the methods shown in the figures. Processor 402 is configured to load and execute instructions, programs, or code 406 by reading memory 404.

[0233] In at least some examples, user equipment device 110 includes: At least one processor 402; and At least one memory 404 stores instructions that, when executed by the at least one processor 402, cause the device to at least: Perform Layer 1 (L1) measurements; Provide an L1 measurement report based on the measurements. If the event-triggered measurement report is active, the first L1 measurement report format is used. If the measurement report triggered by the event is not active, the second L1 measurement report format will be used.

[0236] As shown in Figure 12, instructions, programs, or code 406 can reach the device via any suitable delivery mechanism 408. Delivery mechanism 408 can be, for example, a machine-readable medium, a computer-readable medium, a non-transitory computer-readable storage medium, a computer program product, a memory device, a recording medium such as an optical disc read-only memory (CD-ROM) or digital versatile optical disc (DVD) or solid-state storage, or an article of manufacture that includes or tangibly embodies the computer program 406. The delivery mechanism can be a signal configured to reliably transmit the computer program 406. The device can propagate or transmit the computer program 406 as a computer data signal.

[0237] As used herein, the term “non-transient” refers to a limitation on the medium itself (i.e., tangible, not signaling), rather than a limitation on the persistence of data storage (e.g., RAM vs. ROM).

[0238] In at least some examples, computer program 406 includes instructions for causing user equipment device 110 to perform at least the following operations, or for performing at least the following operations: Perform Layer 1 (L1) measurements; Provide an L1 measurement report based on the measurements. If the event-triggered measurement report is active, the first L1 measurement report format is used.

[0240] Computer program instructions may be contained in a computer program, a non-transitory computer-readable medium, a computer program product, or a machine-readable medium. In some, but not all, examples, computer program instructions may be distributed across more than one computer program.

[0241] Although memory 404 is shown as a single component / circuit, it can be implemented as one or more separate components / circuits, some or all of which may be integrated / removable and / or provide permanent / semi-permanent / dynamic / cached storage.

[0242] Although processor 402 is shown as a single component / circuit, it can be implemented as one or more separate components / circuits, some or all of which may be integrated / removable. Processor 402 may be a single-core or multi-core processor.

[0243] References to “computer-readable storage medium,” “computer program product,” “tangible computer program,” or “controller,” “computer,” “processor,” etc., should be understood to encompass not only computers with different architectures (such as single / multiprocessor architectures and sequential (von Neumann) / parallel architectures) but also special-purpose circuits, such as field-programmable gate arrays (FPGAs), special-purpose circuits (ASICs), signal processing devices, and other processing circuits. References to computer programs, instructions, code, etc., should be understood to encompass software or firmware for programmable processors, such as the programmable content of hardware devices, whether instructions for processors or configuration settings for fixed-function devices, gate arrays, or programmable logic devices.

[0244] As used in this application, the term "circuit" may refer to one or more of the following: (a) Hardware circuit implementation only (such as implementation in analog and / or digital circuits only) and (b) A combination of hardware circuitry and software, such as (if applicable): (i) A combination of (multiple) analog and / or digital hardware circuits and software / firmware, and (ii) Any part of a hardware processor (including (multiple) digital signal processors), software, and one or more memories that works with software to enable a device (such as a mobile phone or server) to perform various functions, and (c) (Multiple) hardware circuits and / or (multiple) processors, such as (multiple) microprocessors or a portion thereof, which require software (e.g. firmware) to operate, but may not exist when operation does not require the software.

[0245] This definition of "circuit" applies to all uses of the term in this application (including in any claim). As another example, as used in this application, the term "circuit" also covers only the implementation of hardware circuitry or processors and their accompanying software and / or firmware. For example, and if applicable to claim elements, the term "circuit" also covers baseband integrated circuits for mobile devices or similar integrated circuits in servers, cellular network devices, or other computing or networking devices.

[0246] The boxes shown in the accompanying drawings may represent steps in the method and / or code segments in computer program 406. The description of a specific order of boxes does not necessarily imply a required or preferred order, and the order and arrangement of boxes can vary. Furthermore, some boxes may be omitted.

[0247] As used herein, a module refers to a unit or device that excludes certain parts / components that will be added by the final manufacturer or user. Such a device can be, for example, a module. The controller 400 of the device can be, for example, a module.

[0248] In the case of a structural feature that has been described, it may be replaced by a component that performs one or more functions for performing that structural feature, whether or not the function or those functions are explicitly or implicitly described.

[0249] The above example can be applied to implement the following components: Automotive systems; telecommunications systems; electronic systems including consumer electronics; distributed computing systems; media systems for generating or rendering media content including audio, visual and audiovisual content, as well as mixed, mediated, virtual and / or augmented reality media content; personal systems including personal health systems or personal fitness systems; navigation systems; user interfaces also known as human-machine interfaces; networks including cellular, non-cellular and optical networks; self-organizing networks; the Internet; the Internet of Things; virtualized networks; and related software and services.

[0250] According to the examples of this disclosure, the device can be provided in an electronic device (e.g., a mobile terminal). However, it should be understood that the mobile terminal is merely an illustration of an electronic device that will benefit from the implementation of this disclosure and should therefore not be construed as limiting the scope of this disclosure. While the device may be provided in a mobile terminal in some implementation examples, other types of electronic devices, such as, but not limited to, mobile communication devices, handheld portable electronic devices, wearable computing devices, portable digital assistants (PDAs), pagers, mobile computers, desktop computers, televisions, gaming devices, laptop computers, cameras, video recorders, GPS devices, and other types of electronic systems, can readily adopt the examples of this disclosure. Furthermore, devices can readily adopt the examples of this disclosure regardless of their intention to provide mobility.

[0251] The term “includes” as used in this document has an inclusive rather than exclusive meaning. That is, any reference to X that includes Y indicates that X may include only one Y or may include more than one Y. If “includes” is intended to be used in an exclusive sense, it will be made clear in the context by referring to “includes only one…” or using “consisting of…”.

[0252] In this specification, the terms “connection,” “coupling,” and “communication,” and their derivatives, mean operatively connecting / coupling / communicating. It should be understood that any number or combination of intermediate components (including none) may be present to provide direct or indirect connection / coupling / communication. Any such intermediate component may include hardware and / or software components.

[0253] As used herein, the term "determine / confirm" (and its grammatical variations) can include at least: calculation, operation, processing, derivation, measurement, investigation, identification, lookup (e.g., searching in a table, database, or other data structure), ascertainment, etc. Furthermore, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data in memory), obtaining, etc. Additionally, "determine" can include parsing, selecting, picking, building, etc.

[0254] Various examples have been referenced in this specification. Descriptions of features or functions of an example indicate which features or functions exist in that example. The use of the terms "example," "for example," "able," or "may" in the text indicates that, whether explicitly stated or not, these features or functions exist at least in the described example, and may, but not necessarily, exist in some or all other examples. Thus, "example," "for example," "able," or "may" refers to a specific instance of a class of examples. An instance's property can be a property of only that instance, or a property of the class, or a property of a subclass of a class that includes some, but not all, instances of that class. Therefore, it is implicitly disclosed that features described with reference to one example, and not another, may be used as part of a working composition in that other example where possible, but are not necessarily required to be used in that other example.

[0255] As used herein, “at least one of the following” and “at least one of…” and similar wording, when a list of two or more elements is connected by “and” or “or”, means at least one, at least two or more, or at least all of those elements.

[0256] Although examples have been described with reference to various examples in the preceding paragraphs, it should be understood that modifications may be made to the given examples without departing from the scope of the claims.

[0257] The features described above can be used in combinations other than those explicitly described above.

[0258] Although some features have been described with reference to certain characteristics, these functions can be performed by other features, whether or not they are described.

[0259] A description of a feature (such as a device or a component of a device) configured to perform a function or for performing a function should also be considered as disclosing a method for performing that function. For example, a description of a device configured to perform one or more actions or for performing one or more actions should also be considered as disclosing a method for performing those one or more actions with or without the device.

[0260] Although features have been described with reference to some examples, these features may also exist in other examples, whether or not they are described.

[0261] The terms “a,” “an,” or “the” are used in this document in an inclusive rather than exclusive sense. That is, any reference to X that includes “a,” “an,” or “the” Y indicates that X may include only one Y or may include more than one Y, unless the context clearly indicates otherwise. If “a,” “an,” or “the” is intended to be used in an exclusive sense, it will be clear from the context. In some cases, the use of “at least one” or “one or more” may be used to emphasize an inclusive meaning, but the omission of these terms should not be construed as inferring any exclusive meaning.

[0262] The presence of a feature (or combination of features) in a claim is a reference to that feature or combination of features itself, as well as to features that achieve substantially the same technical effect (equivalent features). Equivalent features include, for example, features that are variations and achieve substantially the same result in substantially the same manner. Equivalent features include, for example, features that perform substantially the same function in substantially the same manner to achieve substantially the same result.

[0263] In this specification, various examples have been referenced to describe the characteristics of the examples using adjectives or adjective phrases. Such descriptions of the characteristics associated with the examples indicate that the characteristics exist exactly as described in some examples, and substantially as described in others.

[0264] The foregoing description illustrates some examples of this disclosure; however, those skilled in the art will recognize possible alternative structural and methodological features that provide equivalent functionality to the specific examples of such structures and features described above, and for the sake of brevity and clarity, have been omitted from the foregoing description. Nevertheless, the foregoing description should be understood to implicitly include references to such alternative structural and methodological features that provide equivalent functionality, unless such alternative structural or methodological features are explicitly excluded in the foregoing description of the examples of this disclosure.

[0265] Although efforts have been made in the foregoing specification to draw attention to those features deemed important, an applicant may seek protection by means of the claims for any patentable feature or combination of features shown in the foregoing references and / or the accompanying drawings, whether or not they have been emphasized.
