DETAILED DESCRIPTION

Section headings are used in the present document only to improve readability and do not limit scope of the disclosed embodiments and techniques in each section to only that section. Furthermore, some embodiments are described with reference to Third Generation Partnership Project (3GPP) Fifth Generation (5G) New Radio (NR) or Sixth Generation (6G) standard for ease of understanding and the described technology may be implemented in different wireless system that implement protocols other than the NR or 6G protocol.

In the current 3GPP Technical Specification, a UE derives cell measurement results by measuring one or multiple beams associated per cell as configured by the network. FIG. 1 illustrates an example diagram depicting beam measurements and reporting in accordance with one or more embodiments of the present technology. For all cell measurement results, except for Received Signal Strength Indicator (RSSI) and Cross Link Interference (CLI) measurement results in the connected state, the UE applies the layer 3 filtering before using the measured results for evaluation of reporting criteria, measurement reporting, or the criteria to trigger conditional reconfiguration execution. The network may also configure the UE to report measurement information per beam (which can either be measurement results per beam with respective beam identifier (s) or only beam identifier (s)) . For each beam measurement quantity to be derived based on Synchronization Signal (SS) /Physical Broadcast Channel (PBCH) block, also referred to as SSB, the UE derives each configured beam measurement quantity based on the SSB. For each beam measurement quantity to be derived based on CSI-RS, the UE derives each configured beam measurement quantity based on CSI-RS. The time domain behavior of reporting can be configured to be periodic, semi-persistent or aperiodic. The UE reports all the information associated with the reference signals based on the reporting occasions, resulting in a large report overhead and report latency.

This patent document discloses techniques that can be implemented in various embodiments to support event-driven information reporting by the UE at the physical layer, e.g., by configuring a request from the UE indicating the need for a measurement report, to reduce the overhead caused by a large amount of reporting information periodically transmitted by UE and the reporting information that may not change overtime. For example, upon being triggered by an event, the UE can decide whether or not to transmit report information that may be static and/or redundant to reduce reporting overhead. FIG. 2A is a flowchart representation of a method for wireless communication in accordance with one or more embodiments of the present technology. The method 200 includes, at operation 210, transmitting, from a base station, configuration information to a terminal device. The configuration information indicates a number of report configurations comprising a reporting configuration corresponding to one or more signals. The configuration information further indicates at least a request configuration for a request from the terminal device. The method 200 includes, at operation 220, receiving, by the base station, the request based on the request configuration. The method 200 further includes, at operation 230, receiving, by the base station subsequent to the request, a measurement report comprising one or more measurement results of the one or more signals at a physical layer based on the reporting configuration.

FIG. 2B is a flowchart representation of a method for wireless communication in accordance with one or more embodiments of the present technology. The method 250 includes, at operation 260, receiving, by a terminal device, configuration information from a base station. The configuration information indicates a number of report configurations comprising a reporting configuration corresponding to one or more signals. The configuration information further indicates a request configuration for a request to the base station. The method 250 includes, at operation 270, transmitting, by the terminal device, the request based on the request configuration. The method 250 includes, at operation 280, transmitting, by the terminal device subsequent to the request, a measurement report comprising one or more measurement results of the one or more signals at a physical layer based on the reporting configuration.

In some embodiments, the request configuration comprises a first resource for the request to the base station to (1) request a second resource for the measurement report, or (2) to notify a transmission of the measurement report. In some embodiments, the measurement report on the physical layer does not require any L3 filtering or consolidation.

Details regarding the above techniques are further discussed in the embodiments below.

Bit value 0 presents that reporting is not triggered for the report configuration. Bit value 1 presents that reporting is triggered for the report configuration.

In some embodiments, an indication of the number of cells indicates the number of cells for which reporting is triggered or report is requested is indicated in the report request. The indication indicates an integer value and the maximum indicated value is determined by the number of cells configured with report configurations or the number of cells configured for a UE.

In some embodiments, a valid or a positive report request can be considered as a report request indicating non-zero values associated with the triggering of the report triggering. An invalid or a non-positive report request can be considered as a report request indicating zero values associated with the triggering of the report triggering.

In some embodiments, a report request pending is equivalent to the report request is triggered/transmitted and the report request is not canceled, or the positive report request is triggered/transmitted and the negative report request is not triggered/transmitted.

In some embodiments, UE cancels a report request (e.g., a report request transmission, a positive report request transmission or a pending report request) corresponds to a report request configuration in in at least one of the following conditions:

(1) a report associated with the report request has been transmitted by UE,

(2) a report associated with the report request has been transmitted by UE for a maximum of transmission times,

(3) a network message (e.g., a PDCCH or a MAC CE) is received by UE.

In some embodiments, a timer is configured for a report request. UE performs at least one of the following operations related to the timer:

(1) The UE starts or restarts the timer when UE transmits a valid/positive report request.

(2) The UE starts or restarts the timer when a report request is triggered and another report request pending, wherein the report request and another report request correspond to the same report request configuration.

In some embodiments, a report request configuration is associated with a report configuration. The UE starts/restarts the timer when the beam reporting triggering associated with the report configuration is received.

In some embodiments, a report request configuration is associated with more than one report configurations. The UE starts/restarts the timer when the beam reporting triggering associated with any one or more of the more than one report configurations is received.

In some embodiments, a report request configuration is associate with more than one beam report configurations. The UE starts/restarts the timer when the beam reporting triggering associated with a report configuration is received and a former beam reporting triggering associated with a different report configuration has been received.

In some embodiments, a maximum number of transmissions of the report request is configured. The UE performs at least one of the following operations based on a counter configured to count the number of report request transmissions:

(1) The UE increments the counter (e.g., by 1) when UE transmits a valid/positive report request.

(2) The UE increments the counter (e.g., by 1) when a report request is triggered and another report request pending corresponding to the same report request configuration

(3) The UE sets the counter to an initial value (e.g., 0 or 1) when a timer associated with the report request configuration is not running and a report request corresponding to the report request configuration is triggered.

(7) The UE transmits a report (including repetitions if any) when the counter is incremented (e.g., by 1) and the counter does not reach the maximum number of transmissions.

(8) The UE cancels or deactivates a report request transmission or a valid/positive transmission corresponding to a report request configuration when the counter reaches the maximum number of transmissions (e.g., lager or not less than the maximum number of transmissions) .

(9) The UE transmits an invalid/negative report request corresponding to a report request configuration when the counter is lager or not less than the maximum number of transmissions.

In the above embodiments related to canceling a report request or setting a counter, the network message (e.g., PDCCH or MAC CE) schedules an uplink resource for beam information reporting, indicates to cancel a BRQ, indicates to cancel a beam information report transmission, indicates activation of a TCI state, and/or indicates to update a TCI state.

Embodiment 3

This embodiment is related to how a UE evaluates whether a trigger event associated with a report configuration has been triggered.

In some embodiments, the UE evaluates triggering of a trigger event associated with the report configuration based on measurement of at least one of: a first set of reference signals or a second set of reference signals. The first set of reference signals and the second set of reference signals respectively comprise at least one reference signal from one or more reference signals indicated in the report configuration, or from one or more reference signals associated with a specific transmission parameter. The specific transmission parameter can include at least one of the following: a beam (e.g., represented using a signal such as a channel state information reference signal or a synchronization signal block) , a current beam that is being used, an activated TCI state, an indicated TCI state, an applied TCI state, or a TCI state with reference signal with Type-D QCL type.

In some embodiments, the first set of reference signals is associated with a specific transmission parameter while the second set of reference signals is not associated with the specific transmission parameter.

In some embodiments, the first set and the second set of reference signals are indicated in the report configuration. The first set of reference signals is associated with a specific transmission parameter, but the second set of reference signals is not associated with the specific transmission parameter.

In some embodiments, the first set of reference signals is not indicated in the report configuration and is associated with a specific transmission parameter. The second set of reference signals is indicated in the report configuration but is not associated with a specific transmission parameter.

In some embodiments, the report configuration indicates multiple trigger events that are associated with the report configuration. The UE determines the report triggering by evaluating if any or all of the multiple trigger events satisfies a trigger condition. The trigger condition comprises at least one of: a counter related to a triggering indication being equal to or greater than a maximum number, the trigger event occurs, and/or a timer related to the triggering indication is not expired.

In some embodiments, a report is triggered when a first trigger event occurs but a condition for a second trigger event is not satisfied, and a triggering indication counter is greater than or equal to a maximum number. For example, a first trigger event occurs (e.g., when the quality of the current beam is worse than a certain threshold) . However, a condition for a second trigger event (e.g., the quality of at least one new beam becomes better than the current beam) is not satisfied yet, and a triggering indication counter is greater than or equal to a maximum number. In such case, a report is triggered. As another example, a first trigger event occurs (e.g., when the quality of the current beam is worse than a certain threshold) . However, a condition for a second trigger event (e.g., the quality of a new beam is better than a certain threshold) is not satisfied yet and a triggering indication counter is greater than or equal to a maximum number, a report is triggered.

Embodiment 4

The embodiment is related to the UE receiving a signaling from the base station (e.g., a PDCCH) . The signaling schedules/indicates an uplink resource (e.g., PUCCH resource or PUSCH resource) , and triggers/indicates the UE to transmit the beam information report on the uplink resource.

In some embodiments, the signaling (e.g., PDCCH) satisfies at least one of the following conditions:

(1) The PDCCH comprises a field indicating an identification of a report configuration.

(2) The PDCCH comprises a cell identification.

(3) The PDCCH comprises an indication field (e.g., UE initiated report triggering field) indicating that the uplink resource scheduled by the PDCCH is for transmission of a report.

(4) The PDCCH is scrambled with a specific Radio Network Temporary Identifier (RNTI) value specified for event triggered reporting.

(5) The PDCCH comprises a CSI request field, where a codepoint of the CSI request field is associated with a trigger state which is associated with a report configuration.

(6) One or more indication fields in the PDCCH indicate a specific value indicating that the PDCCH is associated with a report.

In some embodiments, when the UE receives a PDCCH comprising a field indicating a cell identification, the CSI request field indicates a report configuration configured on the cell associated with the cell identification, and the UE transmits a report corresponding to the report configuration.

In some embodiments, when the UE receives a PDCCH comprising a field indicating an identification of a report configuration, the UE transmits a report corresponding to the report configuration.

In some embodiments, when a field that indicates UE-initiated reporting (e.g., UE-initiated triggering field) is present in the PDCCH, if value 0 is indicated by the field, the CSI request field is associated with an aperiodic CSI report or semi-persistent CSI report on PUSCH. If value 1 is indicated by the field, the CSI request field is associated with a report configuration, and the UE transmits a report corresponding to the report configuration on the uplink resource.

In some embodiments, when a field that indicates UE-initiated reporting (e.g., UE-initiated triggering field) is present in the PDCCH, if value 0 is indicated by the field, the CSI request field is associated with an aperiodic CSI report or semi-persistent CSI report on PUSCH. If value 1 is indicated by the field, the CSI request field is considered reserved by the UE (e.g., the CSI request field is ignored by the UE) , and UE transmits a report associated with one or more report configurations on the uplink resource.

In some embodiments, when UE receives a PDCCH scrambled by Cell-RNTI (C-RNTI) , and that the PDCCH comprises a field that indicates UE-initiated reporting (e.g., UE-initiated triggering field) having a value of 1, the CSI request field indicates a trigger state associated with a report configuration.

In some embodiments, when the UE receives a PDCCH scrambled by C-RNTI, and that the PDCCH comprises a field that indicates UE-initiated reporting (e.g., UE-initiated triggering field) having a value of 0, the CSI request field indicates a trigger state associated with an aperiodic CSI report; if value 1 is indicated by the field, the CSI request field indicates a trigger state associated with a report configuration.

In some embodiments, when the UE receives a PDCCH scrambled by Semi-Persistent CSI RNTI (SP-CSI-RNTI) , and that the PDCCH comprises a field that indicates UE-initiated reporting (e.g., UE-initiated triggering field) having a value of 0, the CSI request field indicates a trigger state associated with a semi-persistent CSI report on PUSCH. If value 1 is indicated by the field, the CSI request field indicates a trigger state associated with a report configuration.

In some embodiments, when the UE receives a PDCCH scrambled by a RNTI value associated with UE-initiated beam reporting (e.g., UEI-CSI-RNTI) , the CSI request field is associated with a report configuration.

In some embodiments, when the UE receives a PDCCH scrambled by a RNTI value associated with UE-initiated beam reporting (e.g., UEI-CSI-RNTI) , the CSI request field is absent in the PDCCH or the CSI request field is considered reserved, UE transmits a report associated with one or more report configurations on the uplink resource.

Embodiment 5

In some embodiments, as discussed in Embodiment 4, the UE detects a signaling from the base station (e.g., a PDCCH scheduling an uplink resource for transmission of a report or indicating the UE to transmit a report on an uplink resource) or the UE transmits a report on an uplink resource associated with a report configuration. In some embodiments, the UE transmits a report on an uplink resource within a time period that is configured for the uplink resource or for the report. In some embodiments, the scheduled or the associated uplink resource comprises a PUCCH resource, a configured grant PUSCH resource, or a dedicatedly configured PUSCH resource.

In some embodiments, the uplink resource associated with a report configuration is configured in the report configuration or configured in the configuration of beam reporting indicating the beam report configuration. The uplink resource is configured for transmission of a beam information report.

In some embodiments, an uplink resource is configured for a report configuration, and beam information report associated with the report configuration is transmitted on the uplink resource.

In some embodiments, an uplink resource is configured for beam reporting, and beam information report associated with any one or more of the report configurations can be transmitted on the uplink resource, where the report configurations are indicated in the configuration of beam reporting.

In some embodiments, UE does not transmit a UL-SCH transport block on an uplink resource associated with a report configuration. An uplink resource associated with a report configuration refer to a PUSCH without UL-SCH or a PUSCH without transport block, or a PUSCH in which a report is multiplexed.

In some embodiments, the report transmitted on the uplink resource is associated with one or more report configurations.

In some embodiments, the UE detects a PDCCH scheduling an uplink resource for transmission of a report or UE transmits a beam information report on an uplink resource after the UE transmits an uplink resource corresponding to a report configuration.

In some embodiments, when UE is configured with an uplink resource for transmission of a beam information report, UE transmits a beam information report on the uplink resource. Otherwise, UE transmits a beam information report on an uplink resource scheduled by a PDCCH.

In some embodiments, the UE does not expect to receive a PDCCH indicating that the UE needs to transmit a report when at least one of the following conditions is satisfied:

(1) The PDCCH is received a number of time units after a slot/alast symbol/afirst symbol of an uplink resource transmission of the report request.

(2) The PDCCH is received a number of time units after a slot/alast symbol/afirst symbol of a latest transmission of the report.

Here, a time unit can be an OFDM symbol, a slot and/or a millisecond. The number of time units is determined according to at least one of a PUSCH preparation time, a period of a report request configuration, a configured value, and/or a predefined value.

In some embodiments, after the UE transmits a report on an uplink resource configured for transmission of the report. Upon receiving a PDCCH that indicates/triggers the UE to transmit the report on the PUSCH scheduled by the PDCCH, the UE transmits the report on the PUSCH scheduled by the PDCCH.

In some embodiments, the PDCCH indicating that the UE is to transmit the report comprises an indication field indicative of whether the report is an initial transmission or retransmission. In some embodiments, the indication field comprises a new data indication (NDI) field or a beam report retransmission indication field (e.g., with one bit) . In some embodiments, the bit value of the indication field being zero indicates an initial transmission of a report is on the PUSCH. The bit value of the indication field being one indicates the report is a retransmission (e.g., a retransmission of a beam information report is on the PUSCH) .

In some embodiments, the indication field indicates a toggle between an initial transmission and a retransmission. When the bit value of the indication field in a PDCCH is the same as that in a previously received PDCCH, the PDCCH indicates an initial transmission. When the bit value of the indication field in a PDCCH is different from that in a previously received PDCCH, the PDCCH indicates a retransmission. The PDCCH and the previously received PDCCH can both be associated with the beam report.

In some embodiments, after the UE transmits a report associated with one or more report configurations, if the UE receives a PDCCH indicating a retransmission of a report, the UE transmits the report associated with the one or more report configurations on the uplink resource scheduled by the PDCCH.

In some embodiments, after the UE transmits a report associated with one or more report configurations, if the UE receives a PDCCH indicating an initial transmission of a report, the UE transmits a report not associated with the one or more report configurations (if any) on the uplink resource scheduled by the PDCCH or the UE does not transmit a report associated with the one or more report configurations on the uplink resource scheduled by the PDCCH.

In some embodiments, after the UE transmits a report request associated with one or more report configurations, if the UE receives a PDCCH indicating an initial transmission of a report, the UE transmits a report associated with the one or more report configurations (if any) on the uplink resource scheduled by the PDCCH. If the UE receives a PDCCH indicating an retransmission of a report, the UE does not transmit a report associated with the one or more report configurations (if any) on the uplink resource scheduled by the PDCCH.

In some embodiments, the UE transmits a report in an uplink resource configured for transmission of the report when the UE does not receive a PDCCH or the report has not been transmitted. (e.g., it is the first/initial transmission) . The UE transmits a report in an uplink resource scheduled by a PDCCH when the UE receives the PDCCH and the report has been transmitted. (e.g., it is not the first/initial transmission) .

In some embodiments, the UE transmits a report in an uplink resource configured for transmission of the beam information report when the UE does not receive a PDCCH. The UE transmits a report in an uplink resource scheduled by a PDCCH when the UE receives the PDCCH.

In some embodiments, the UE transmits a report before receiving a network message (e.g., a PDCCH or a MAC CE) indicating to stop/cancel/deactivate transmissions of the report. In some embodiments, the UE periodically transmits a report before receiving a network message. In some embodiments, a PDCCH comprises an indication field indicates an identifier or index of a report configuration associated with the report. In some embodiments, a MAC CE comprises one or more deactivation indication fields. Each deactivation indication field indicates the stopping/canceling/deactivation status of a report or a report configuration associated with the field. The field being set to 1 indicates that the transmission of the corresponding report is to be stopped/canceled/deactivated.

In some embodiments, the UE does not transmit a report or does not transmit (e.g., cancel) an uplink resource for report request after receiving a TCI states activation/deactivation MAC CE, TCI State Indication MAC CE, or a PDCCH comprising a TCI field indicating to update a TCI state that is applied or applicable to UE. The report or the uplink transmission for report request is triggered before receiving the TCI states activation/deactivation MAC CE, the TCI MAC CE, and/or the PDCCH.

In some embodiments, the UE does not transmit anything on a uplink resource associated with a report configuration or a report if the higher layers have not delivered a transport block to transmit on the resource and/or if a report is not transmitted or multiplexed on the resource.

If a bit indicates a value 1, fields correspond to a report configuration associated with the cell that is associated with the bit are present in the report. If a bit indicates a value 0, fields correspond to a report configuration associated with the cell that is associated with the bit are absent or reserved in the report.

In some embodiments, an indication of the number of report configurations is associated with an identifier of a cell, and it indicates the number of report configurations for which beam reporting is triggered or beam information report is requested. The maximum indicated value is determined based on the maximum number of report configurations.

In some embodiments, if an identifier of a cell indicates a zero value (e.g., beam reporting is not triggered for the cell) , the indication of the number of report configurations associated with the cell indicates a zero value.

In some embodiments, an identifier of a report configuration is associated with an identifier of a cell, and it explicitly indicates an index of the report configuration associated with the cell.

In some embodiments, an identifier of a report configuration is associated with an identifier of a cell, and codepoints of the identifier of report configuration are mapped to report configurations one by one. The mapping can be based on the order of the indexes of report configurations. (e.g., identifier with value 0 corresponds to the lowest report configuration index, value 1 corresponds to the second lowest beam report configuration index, and so on. )

In some embodiments, codepoints of the identifier of report configuration are mapped to report configurations one by one. The mapping can be based on the order of the indexes of beam report configurations which are configured to transmit the report as above.

In some embodiments, an indication indicates the presence of indication fields (e.g., reference signal index and/or report quantity) associated with a report configuration. If the presence indication indicates a value 1, fields of reference signal index and/or report quantity associated with the beam report configuration are present. If the presence indication indicates a value 0, fields of reference signal index and/or report quantity associated with the report configuration are absent.

In some embodiments, one or more sets of fields of reference signal index and/or report quantity are present in a report. Multiple sets of fields can be associated with a report configuration. For example, a report configuration indicates a maximum number of reference signals to be reported or a number of reference signals (e.g., fixed number) to be reported. The number of sets of fields then equals to the maximum number of reference signals or the number of reference signals (e.g., fixed number) to be reported. Within each set, various fields can be used to indicate information regarding respective reference signals. In some embodiments, an indication of the number of reported reference signals associated with a report configuration indicates the number of sets of fields associated with the report configuration in the report.

The disclosed and other embodiments, modules and the functional operations described in this document can be implemented in digital electronic circuitry, or in computer software, firmware, or hardware, including the structures disclosed in this document and their structural equivalents, or in combinations of one or more of them. The disclosed and other embodiments can be implemented as one or more computer program products, i.e., one or more modules of computer program instructions encoded on a computer readable medium for execution by, or to control the operation of, data processing apparatus. The computer readable medium can be a machine-readable storage device, a machine-readable storage substrate, a memory device, a composition of matter effecting a machine-readable propagated signal, or a combination of one or more them. The term “data processing apparatus” encompasses all apparatus, devices, and machines for processing data, including by way of example a programmable processor, a computer, or multiple processors or computers. The apparatus can include, in addition to hardware, code that creates an execution environment for the computer program in question, e.g., code that constitutes processor firmware, a protocol stack, a database management system, an operating system, or a combination of one or more of them. A propagated signal is an artificially generated signal, e.g., a machine-generated electrical, optical, or electromagnetic signal, that is generated to encode information for transmission to suitable receiver apparatus.

A computer program (also known as a program, software, software application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program does not necessarily correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document) , in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code) . A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.

The processes and logic flows described in this document can be performed by one or more programmable processors executing one or more computer programs to perform functions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit) . Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read only memory or a random-access memory or both. The essential elements of a computer are a processor for performing instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto optical disks, or optical disks. However, a computer need not have such devices. Computer readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto optical disks; and CD ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.

It is noted that operation of the wireless communications as disclosed herein causes a reduction in greenhouse gas emissions compared to traditional methods. The International Energy Agency (IEA) estimates that the overall share of carbon emissions from information and communication technologies (ICT) accounts for approximately 4%of the total amount of CO₂ emitted around world. Further, conventional networks can sometimes exacerbate the causes of climate change. For example, at an average of approximately 485g of CO₂ per KWh of electricity that is produced worldwide, it results in a rough estimate of 145.5 million metric tons of CO₂. The implementations disclosed herein for operating the wireless communications can reduce power consumption by reducing reporting overhead and latency. For example, the timely reporting of the beam information at the physical layer can help avoid unnecessary consumption in conventional procedures (e.g., reporting consolidation) .

Moreover, Global System for Mobile Communications Association (GSMA) , the organization that represents mobile operators and the telecommunication industry worldwide, has estimated that currently 20–40%of the operating cost of network operators is taken up by electricity, and that 5G can cause a substantial (as much as four to five fold) increase of energy consumption in the RAN, but that the technical means to reduce this consumption can be included in later generation mobile networks, such as 6G networks. Expanding the reporting capabilities using the embodiments disclosed herein can enable efficient beam reporting to obviate the need for wasteful CO₂ emissions. Therefore, the disclosed implementations for operation of the wireless communications mitigates climate change and the effects of climate change.
