[0024] Detailed embodiments and implementations of the claimed subject matters are disclosed herein. However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview
[0025] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to energy efficiency feedback for joint system energy saving in mobile communications. According to the present disclosure, a number of possible solutions may be implemented separately or jointly. That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.
[0026] In modern mobile communication technology, reducing power consumption while maintaining high performance is a crucial challenge. As network bandwidth expands, base stations (BSs) , such as 5G base stations (gNB) , are deployed more densely. In addition, user devices demand higher data rates and longer battery life. Therefore, power saving technologies play a critical role not only in network operational costs but also in user experience. Through effective power saving technologies, energy efficiency on both the network and user device sides can be improved in current mobile communications, achieving a good balance between high speed, low latency, and energy conservation. These power saving strategies are developed in different domains, including the spatial domain, the time domain, the power domain, and the frequency domain.
[0027] For network-side power saving, the BS may employ multiple techniques to reduce power consumption while maintaining communication performance. In the spatial domain, the BS may leverage antenna domain adaptation, which dynamically adjusts the number of active Multiple-Input Multiple-Output (MIMO) antennas based on UE location to minimize unnecessary power usage. In the time domain, Discontinuous Transmission (DTX) or Discontinuous Reception (DRX) reduces signal transmission during idle periods to save energy, and the cell active window allows the BS to enter sleep mode during low traffic periods, preventing prolonged high-power transmission. In the power domain, transmission power adaptation dynamically adjusts transmission power based on User Equipment (UE) location and channel conditions, avoiding excessive energy usage. In the frequency domain, dynamic bandwidth allocation enables the BS to modify carrier bandwidth based on network traffic demand, reducing power consumption in high-frequency bands.
[0028] For UE-side power saving, the UE may employ various techniques to extend battery life and reduce communication load. In the spatial domain, beam management allows the UE to select the optimal beam, minimizing reception power consumption. In the time domain, DRX enables the UE to enter sleep mode during periods of no data transmission and periodically wake up to monitor network signals, thereby conserving battery life. In the power domain, Physical Downlink Control Channel (PDCCH) monitoring reduction ensures that the UE only listens to control signals when necessary, reducing the processing burden. In the frequency domain, bandwidth adaptation allows the UE to use narrower bandwidths during low-traffic periods, reducing RF module power consumption. Additionally, UE Assistance Information (UAI) enables the UE to proactively report traffic demand and battery status, allowing the network to dynamically adjust power saving strategies to enhance overall energy efficiency.
[0029] Through these multi-domain power saving strategies or schemes, the high-speed performance and energy efficiency can be balanced.
[0030] However, the power saving scheme adopted at the network-side and the power saving scheme adopted at the UE-side are determined independently. When considering joint system energy saving, the power saving scheme adopted at the network-side and the power saving scheme adopted at the UE-side may not be the optimal selection. Given a network setting and different loading cases, it lacks an efficient way to decide a suitable power saving scheme.
[0031] To address the issue of how to optimize the determination or selection among various power saving schemes, methods and apparatus for energy efficiency feedback to achieve joint system energy saving in mobile communications are introduced. The feedback of energy efficiency facilitates the determination of a suitable or optimal power saving scheme.
[0032] In some implementations, the metrics for evaluating energy efficiency (EE) related value and joint EE related value of a power saving scheme may be determined or calculated as the following equations Eq. (1) and Eq. (2) : where the value BS_EEbase represents the baseline EE related value of BS, the value UE_EEbase represents the baseline EE related value of UE, the value BS_EEadapt represents the adapted EE related value of BS and the value UE_EEadapt represents the adapted EE related value of UE, and α, β are the weighting factors for BS and UE, respectively. Note that the metrics for evaluating the EE related value and joint EE related value may also be determined or calculated based on other different ways, and the invention is not limited to equations Eq. (1) and Eq. (2) .
[0033] The baseline EE related value of BS may be calculated or determined based on the currently adopted power saving scheme of BS, and the baseline EE related value of UE may be calculated or determined based on the currently configured power saving scheme of UE. The adapted EE related value of BS may be a prediction result and may be calculated or determined based on a potential power saving scheme or a power saving scheme candidate that may be adopted by the BS in the future. The adapted EE related value of the UE may be a prediction result and may be calculated or determined based on a potential power saving scheme or a power saving scheme candidate that may be configured by the BS to the UE in the future. The joint EE related value may indicate the degree of improvement of the power saving scheme candidate with respect to the currently adopted or configured power saving scheme.
[0034] In some implementations, the power consumption (PC) may be determined or calculated as the following equation Eq. (3) : PC=∑i PiTi Eq. (3) where the value Pi represents the power consumption of a power state i and the value Ti is the time ratio of the power state i.
[0035] The value Pi may be determined based on a power model of the corresponding device (e.g., BS or UE) , and may be scaled according to different power saving schemes. The value Ti may be deduced from a timeline model and ∑i Ti=1.
[0036] The timeline model may be a prediction window to model the power states within a period of time. The window length of the timeline model may span at least one data inter-arrival. The timeline model may comprise periodic behavior, such as reference signal transmission / reception, DRX operation, cell-DTRX operation, etc., and may also comprise aperiodic behavior, such as downlink / uplink (DL / UL) data, Hybrid Automatic Repeat reQuest (HARQ) response, etc., of the corresponding device.
[0037] In some implementations, the channel state information (CSI) may be utilized in DL / UL data duration prediction. In some implementations, the ways to model the data pattern may comprise consecutive traffic, equal interval of the data slots within a span, irregular interval, an Artificial Intelligence (AI) model data pattern, etc.
[0038] The joint EE related value may be determined or calculated by the BS or UE. In the first mechanism (mechanism 1) , the joint EE related value may be determined or calculated by the BS based on the UE_EE fed back or reported by the UE. In the second mechanism (mechanism 2) , the joint EE related value may be determined or calculated by the UE based on the BS_EE fed back or provided by the BS.
[0039] Specifically, in the first mechanism, an apparatus (e.g., the UE) may receive a report configuration from a network node (e.g., the BS) . The report configuration may comprise at least one report setting associated with at least one power saving scheme, and there may be multiple power saving schemes associated with a report setting.
[0040] The UE may determine the EE related value associated with the power saving scheme and transmit a report carrying information regarding the EE related value to the BS according to the report setting.
[0041] The power saving scheme (s) in report configuration may comprise the potential power saving scheme (s) or the power saving scheme candidate (s) that may be configured by the BS to the UE in the future. In addition, the power saving schemes may be implemented in different domains, including the spatial domain, the time domain, the power domain, and the frequency domain.
[0042] The BS may indicate one or more power saving scheme candidates in the report configuration with their associated report setting (s) , for the UE to predict, deduce or infer the EE related values associated with the power saving scheme candidates and feedback or report the predicted, deduced or inferred results.
[0043] The EE related value reported by the UE may be the UE_EEadapt or the ratio UE_EEadapt / UE_EEbase as illustrated in Eq. (2) , or may be any value or metric for evaluating the EE or any value derived based on the UE_EEadapt and / or the UE_EEbase.
[0044] In some implementations, the UE may further determine CSI according to the report configuration, and the report may further carry the CSI. The EE related value and the CSI may be reported together in one report, or may be reported separately.
[0045] The report setting may comprise a periodic report setting, a semi-persistent report setting, or an aperiodic report setting. The BS may configure one or more than one types of report setting to the UE. For example, the BS may configure both periodic report setting and aperiodic report setting to the UE.
[0046] The report setting may indicate one or more reference signals (RS) associated with the power saving scheme. The EE related value may be determined according to the RS. For example, the EE related value may be determined based on a measurement result associated with the RS.
[0047] The EE related value may be determined by bits per joule. For example, the EE related value may be determined according to a number of transmitted or received bits and power consumption associated with the power saving scheme (e.g., a ratio of the total transmitted or received bits and the power consumption as illustrated in Eq. (1) ) .
[0048] In some implementations, the EE related value may be determined based on a prediction model. For example, the number of transmitted or received bits and the power consumption may be both predicted values determined based on the prediction model.
[0049] Regarding operations associated with the network node (e.g., the BS) in the first mechanism, the BS may transmit a report configuration to the UE and receive a report from the UE. The report configuration may comprise at least one report setting associated with a first power saving scheme, and the report may carry information regarding a first EE related value associated with the first power saving scheme.
[0050] The BS may determine a second EE related value associated with the first power saving scheme and determine a first joint EE related value according to the first EE related value and the second EE related value.
[0051] In some implementations, the first power saving scheme indicated in report configuration may be the potential power saving scheme or the power saving scheme candidate that may be configured or adopted in the future.
[0052] The first EE related value may be the UE_EEadapt or the ratio UE_EEadapt / UE_EEbase as illustrated in Eq. (2) , or may be any value or metric for evaluating the EE or any value derived based on the UE_EEadapt and / or the UE_EEbase. The second EE related value may be the BS_EEadapt or the ratio BS_EEadapt / BS_EEbase as illustrated in Eq. (2) , or may be any value or metric for evaluating the EE or any value derived based on the BS_EEadapt and / or the BS_EEbase. The first joint EE related value may be determined according to Eq. (2) .
[0053] In some implementations, the report may further carry CSI determined according to the report configuration, and the BS may determine the second EE related value according to the CSI. Note that the EE related value and the CSI may be reported jointly in one report or may be reported separately.
[0054] In some implementations, the report configuration may further comprise at least one report setting associated with a second power saving scheme, and the report may further carry information regarding a third EE related value determined by the UE and associated with the second power saving scheme. In some implementations, a report may carry information regarding the EE related value (s) of one power saving scheme or the EE related values of more than one power saving scheme.
[0055] The BS may determine a fourth EE related value associated with the second power saving scheme and determine a second joint EE related value according to the third EE related value and the fourth EE related value.
[0056] Similarly, the second power saving scheme indicated in report configuration may be the potential power saving scheme or the power saving scheme candidate that may be configured or adopted in the future.
[0057] The third EE related value may be the UE_EEadapt or the ratio UE_EEadapt / UE_EEbase as illustrated in Eq. (2) , or may be any value or metric for evaluating the EE or any value derived based on the UE_EEadapt and / or the UE_EEbase. The fourth EE related value may be the BS_EEadapt or the ratio BS_EEadapt / BS_EEbase as illustrated in Eq. (2) , or may be any value or metric for evaluating the EE or any value derived based on the BS_EEadapt and / or the BS_EEbase. The second joint EE related value may be determined according to Eq. (2) .
[0058] The BS may further determine a preferred power saving scheme according to the first joint EE related value and the second joint EE related value. In some embodiments, the BS may collect more feedback from different UEs, determine multiple joint EEs with respect to different power saving schemes and different UEs, and determine a preferred power saving scheme according to the values of the joint EEs. The BS may configure the preferred power saving scheme to the corresponding UE when required. For example, when the preferred power saving scheme of a UE is different from the currently configured one.
[0059] FIG. 1 illustrates an example scenario 100 of periodic report based on the first mechanism in accordance with an implementation of the present disclosure. The BS may pre-configure one or more report settings associated with one or more power saving schemes to be assessed via higher layer signaling. For example, the BS may transmit a report configuration comprising the one or more report settings via a Radio Resource Control (RRC) signaling. The one or more power saving schemes to be assessed may be the aforementioned potential power saving schemes or power saving scheme candidates that may be configured by the BS in the future.
[0060] In scenario 100, the one or more report settings may comprise periodic report setting (s) . In the periodic report setting, the transmitting of the report may be performed periodically.
[0061] In some implementations, at least one periodic RS may be associated with the one or more power saving schemes for periodic reporting. The report configuration or the periodic report setting may indicate which periodic RS is associated with the one or more power saving schemes, or the periodic RS may carry the information regarding the associated power saving scheme. In the periodic reporting, the EE related value may be determined according to the periodic RS. For example, the EE related value may be determined based on a measurement result associated with the periodic RS.
[0062] The UE may calculate the CSI and UE_EE associated with the one or more power saving schemes according to the configurations of the one or more power saving schemes in the periodic report setting (s) . In some implementations, the UE may predict, deduce or infer the timeline model and / or the UE_EE from the CSI. For example, an AI model may be used to predict, deduce or infer the timeline model and / or the associated UE_EE.
[0063] The UE may report or feedback the CSI and the UE_EE periodically. The BS may collect the UE feedbacks, and calculate the BS_EE and one or more Joint_EE with respect to different power saving schemes. The BS may make decisions based on the one or more Joint_EE. For example, the BS may determine a preferred power saving scheme according to the values of the one or more Joint_EE. The BS may configure the preferred power saving scheme to the corresponding UE when required.
[0064] FIG. 2 illustrates an example scenario 200 of semi-persistent report based on the first mechanism in accordance with an implementation of the present disclosure. The BS may pre-configure one or more report settings associated with one or more power saving schemes to be assessed via the higher layer signaling. For example, the BS may transmit a report configuration comprising the one or more report settings via an RRC signaling.
[0065] In scenario 200, the one or more report settings may comprise semi-persistent report setting (s) . In the semi-persistent report setting, the transmitting of the report may be performed periodically in response to an activation of the semi-persistent report setting. The BS may transmit an activation signal to activate the semi-persistent report setting (s) .
[0066] In some implementations, a periodic RS or a semi-persistent RS may be associated with the one or more power saving schemes for semi-persistent reporting. The report configuration or the semi-persistent report setting may indicate which periodic RS or which semi-persistent RS is associated with the one or more power saving schemes, or the periodic RS or the semi-persistent RS may carry the information regarding the associated power saving scheme. In the semi-persistent reporting, the EE related value may be determined according to the periodic RS or the semi-persistent RS.
[0067] In response to the reception of the activation signal to activate the semi-persistent report setting (s) , the UE may calculate the CSI and the UE_EE associated with the one or more power saving schemes according to the configurations of the one or more power saving schemes in the semi-persistent report setting (s) . In some implementations, the UE may predict, deduce or infer the timeline model and / or the UE_EE from the CSI. For example, an AI model may be used to predict, deduce or infer the timeline model and / or the associated UE_EE.
[0068] The UE may report or feedback the CSI and the UE_EE periodically. The BS may collect the UE feedbacks, and calculate the BS_EE and one or more Joint_EE with respect to different power saving schemes. The BS may make decisions based on the one or more Joint_EE. For example, the BS may determine a preferred power saving scheme according to the values of the one or more Joint_EE. The BS may configure the preferred power saving scheme to the corresponding UE when required.
[0069] The BS may further transmit a de-activation signal to de-activate the semi-persistent report setting (s) .
[0070] FIG. 3 illustrates an example scenario 300 of aperiodic report based on the first mechanism in accordance with an implementation of the present disclosure. The BS may pre-configure one or more report settings associated with one or more power saving schemes to be assessed via higher layer signaling. For example, the BS may transmit a report configuration comprising the one or more report settings via an RRC signaling.
[0071] In scenario 300, the one or more report settings may comprise aperiodic report setting (s) . In the aperiodic report setting, the transmitting of the report may be performed in response to the triggering of the aperiodic report setting. The BS may transmit a triggering signal to trigger the aperiodic report setting.
[0072] In some implementations, a periodic RS, a semi-persistent RS or an aperiodic RS may be associated with the one or more power saving schemes for aperiodic reporting. The report configuration or the aperiodic report setting may indicate which periodic RS, which semi-persistent RS or which aperiodic RS is associated with the one or more power saving schemes, or the periodic RS, the semi-persistent RS or the aperiodic RS may carry the information regarding the associated power saving scheme. In the aperiodic reporting, the EE related value may be determined according to the periodic RS, the semi-persistent RS or the aperiodic RS.
[0073] In response to the reception of the triggering signal to trigger the aperiodic report setting (s) , the UE may calculate the CSI and the UE_EE associated with the one or more power saving schemes according to the configurations of the one or more power saving schemes in the aperiodic report setting (s) . In some implementations, the UE may predict, deduce or infer the timeline model and / or the UE_EE from the CSI. For example, an AI model may be used to predict, deduce or infer the timeline model and / or the associated UE_EE.
[0074] The UE may report or feedback the CSI and the UE_EE. The BS may collect the UE feedback, and calculate the BS_EE and one or more Joint_EE with respect to different power saving schemes. The BS may make decisions based on the one or more Joint_EE. For example, the BS may determine a preferred power saving scheme according to the values of the one or more Joint_EE. The BS may configure the preferred power saving scheme to the corresponding UE when required.
[0075] In the second mechanism, the UE may receive a report configuration from the BS. The report configuration may comprise at least one report setting associated with at least one power saving scheme, wherein there may be multiple power saving schemes associated with a report setting. The BS may indicate one or more power saving scheme candidates in the report configuration with their associated report settings, for the UE to predict, deduce or infer the EE related values associated with the power saving scheme candidates and feedback or report the predicted, deduced or inferred results.
[0076] The report setting may comprise a periodic report setting, a semi-persistent report setting, or an aperiodic report setting. The BS may configure one or more than one types of report setting to the UE. For example, the BS may configure both semi-persistent report setting and aperiodic report setting to the UE.
[0077] The UE may determine CSI according to the report configuration and transmit a report carrying the CSI to the BS.
[0078] The UE may further receive information regarding one or more first EE related values associated with a set of power saving schemes from the BS and determine one or more second EE related values associated with the set of power saving schemes configured by the BS in the report configuration. The one or more first EE related values may be determined according to the CSI reported by the UE.
[0079] The report setting may indicate one or more RSs associated with the set of power saving schemes. The one or more second EE related values value may be determined according to the RS (s) . For example, the EE related value may be determined based on a measurement result associated with the RS.
[0080] The set of power saving schemes may comprise one or more potential power saving schemes or one or more power saving scheme candidates that may be configured or adopted in the future. The set of power saving schemes may be implemented in different domains, including the spatial domain, the time domain, the power domain, and the frequency domain.
[0081] The one or more first EE related values provided by the BS may be the BS_EEadapt or the ratio BS_EEadapt / BS_EEbase as illustrated in Eq. (2) , or may be any value or metric for evaluating the EE or any value derived based on the BS_EEadapt and / or the BS_EEbase.
[0082] Similarly, the one or more second EE related values determined by the UE may be the UE_EEadapt or the ratio UE_EEadapt / UE_EEbase as illustrated in Eq. (2) , or may be any value or metric for evaluating the EE or any value derived based on the UE_EEadapt and / or the UE_EEbase.
[0083] In addition, the first and second EE related values may be determined by bits per joule. For example, the EE related value may be determined according to a number of transmitted or received bits and power consumption associated with the corresponding power saving scheme (e.g., a ratio of the total transmitted or received bits and the power consumption as illustrated in Eq. (1) ) .
[0084] In some implementations, the first and second EE related values may be respectively determined based on a prediction model. For example, the number of transmitted or received bits and the power consumption may be both predicted values determined based on the prediction model.
[0085] With the information regarding the one or more first EE related values and the one or more second EE related values, the UE may determine one or more joint EE related values according to the one or more first EE related values and the one or more second EE related values, and transmit information regarding the one or more joint EE related values to the network node.
[0086] In some implementations, the UE may also transmit information regarding one or more suggested power saving schemes, information regarding the ranking of the power saving schemes in the set of power saving schemes to the BS, or transmit information regarding expected compensation in an event that the one or more suggested power saving schemes is / are not chosen by the BS. The suggested power saving schemes, the ranking of the power saving schemes or the expected compensation may be determined based on the one or more joint EE related values.
[0087] Regarding operations associated with the BS in the second mechanism, the BS may transmit a report configuration to the UE and receive a report carrying the CSI from the UE.

[0090] The BS may further determine a preferred power saving scheme according to the one or more joint EE related values or the aforementioned information provided by the UE. In some embodiments, the BS may collect more feedback from different UEs and determine a preferred power saving scheme according to the feedback. The BS may configure the preferred power saving scheme to the corresponding UE when required. For example, when the preferred power saving scheme of a UE is different from the currently configured one.
[0091] FIG. 4 illustrates an example scenario 400 of periodic report based on the second mechanism in accordance with an implementation of the present disclosure.

[0159] The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected" , or "operably coupled" , to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being "operably couplable" , to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and / or physically interacting components and / or wirelessly interactable and / or wirelessly interacting components and / or logically interacting and / or logically interactable components.
[0160] Further, with respect to the use of substantially any plural and / or singular terms herein, those having skill in the art can translate from the plural to the singular and / or from the singular to the plural as is appropriate to the context and / or application. The various singular / plural permutations may be expressly set forth herein for sake of clarity.
[0161] Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to, ” the term “having” should be interpreted as “having at least, ” the term “includes” should be interpreted as “includes but is not limited to, ” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an, " e.g., “a” and / or “an” should be interpreted to mean “at least one” or “one or more; ” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of "two recitations, " without other modifiers, means at least two recitations, or two or more recitations.
