Detailed Implementation

[0023] In exemplary embodiments of the present invention, at least one method and apparatus for network coordination are proposed to minimize UE power consumption and extend battery life, while taking into account QoS requirements, system aspects, and without disclosing potentially confidential UE information.

[0024] One of the most power-consuming components in gNB and UE equipment is the power amplifier, so maximizing its efficiency is crucial for better energy efficiency and power savings. Power amplifier efficiency depends on its own architecture (PA class, PA with envelope tracking, Doherty PA, etc.) and other parameters.

[0025] The peak-to-average power ratio (PAPR) of the PA input signal, as well as linearity / error vector magnitude (EVM) / adjusted channel leakage ratio (ACLR) and other requirements, define the required PA output power back-off (OBO) for the PA, thus defining the achievable maximum PA efficiency (at Pcmax) for a given PA architecture and a given waveform / modulation (e.g., high PAPR -> high OBO -> lower PA efficiency). However, the operational input / output power level can also affect instantaneous PA efficiency and power consumption (e.g., battery life) compared to the PA's maximum input / output power level. For example, the PA-added efficiency (PAE) of a front-end module with a duplexer for operation in the new frequency bands n7, n38, n40, and n41 of 4G and 5G LTE frequency division duplex (FDD) / time division duplex (TDD) operating between 2.3 GHz and 2.7 GHz is... Figure 2 As shown in the figure (see F. Balteanu, “RF Front End Module Architectures for 5G,” 2019 IEEE BiCMOS and Compound Semiconductor Integrated Circuits and Technology Symposium (BCICTS), Nashville, TN, USA, 2019, pp. 1-8). Specifically, Figure 2 The PAE curves for a 3.5GHz GaAs PA for the 5G n77 / n78 band are shown.

[0026] like Figure 2 As shown, a PA architecture with envelope tracking (ET) can improve PA efficiency at high output power levels near maximum power, rather than at low output power levels. Note that not all UEs have a PA architecture with ET. Figure 2 As shown, even with advanced PA technologies that have perfect synchronization (such as ET), the PAE is low at low output power.

[0027] The 3GPP (3rd Generation Partnership Project) technical specifications describe uplink (UL) closed-loop power control, whereby the UE transmit power can be adjusted by the gNB in ​​the UL based on path loss or the configuration provided by the gNB. For example, the UE transmit power for the Physical Uplink Shared Channel (PUSCH) can be determined based on the following, as described in 3GPP TS 38.213: , The transmission power is limited, and this limit is defined as the maximum output power configured by the UE. The UE can set the PCMAX,f,c value in each time slot, provided that PCMAX,f,c is set within the boundary. PCMAX_L,f,c ≤PCMAX,f,c≤PCMAX_H,f,c, Where, PCMAX_L,f,c = MIN {PEMAX,c– TC,c,(PPowerClass – ΔPPowerClass) –MAX(MAX(MPRc+ MPRc, A-MPRc)+ ΔTIB,c + TC,c + TRxSRS, P-MPRc)}, and PCMAX_H,f,c = MIN {PEMAX,c,PPowerClass – ΔPPowerClass}.

[0028] In this example, the gNB cannot know the exact PCMAX,f,c(i) that the UE can configure in a timely manner because the report of PCMAX,f,c(i) must be carried with the PHR. Therefore, what the gNB can continuously know is the upper and lower limits of PCMAX,f,c(i).

[0029] The UE can be configured to report PHR using the PHR Media Access Control Unit (MAC CE). The MAC CE can report the margin between the current UE Tx power (e.g., estimated power) and the nominal maximum UE transmit power defined in 3GPP TS 38.321 or the configured maximum power defined in 3GPP TS 38.101 / 38.213. PHR reporting can support power-aware packet scheduling and allow the network to select appropriate UL bandwidth and modulation and coding scheme (MCS) on a specific subframe without exceeding UE power limits. Additionally, the PHR can indicate the amount of transmit power remaining available to the UE beyond the power currently used by the transmission, such as... Figure 3 As shown. Specifically, Figure 3 The PHR using the estimated Tx PUSCH power is shown. The PHR reporting range can be from -0.23 to +40 dB, and the reporting map can have a 1 dB granularity. The determination of the remaining power margin can be expressed by the following equation: Power margin (PH) .

[0030] Currently, UE power consumption optimization and related signaling between the UE and gNB do not consider UE PA characteristics (e.g., efficiency, power consumption, etc.). Furthermore, there is no 3GPP signaling to the gNB to indicate auxiliary information regarding the UE's preferred UL power or an appropriate power that can help reduce UE power consumption. For example, operating at low output power may consume more power due to reduced PA efficiency and a potential increase in transmission time. Moreover, always operating at maximum power may lead to high cell interference and / or UE thermal / battery issues, and the UE may unnecessarily consume power if there is no data to transmit or QoS requirements are already met. The optimal operating power for a specific QoS can depend on UE PA efficiency, UE state (e.g., UL buffer), energy consumption characteristics, and system-level aspects of the communication system, cell, or network (e.g., interference management, etc.).

[0031] As a non-limiting example, regarding interference management, a network can perform interference management by carefully scheduling, multiplexing, and allocating resources (in the time / frequency / spatial domain) for UE downlink (DL) and UL transmissions and / or by controlling DL and UL transmission power to reduce all possible interference (e.g., intra-cell, inter-cell, etc.) while meeting QoS (throughput, latency, etc.) for most UEs. In other examples, the optimal power operating point can be based solely on UE efficiency, or also on network considerations for overall system aspects (e.g., interference management). The optimal power operating point can be based on UE efficiency only in very few cases (if any), such as: low cell load; very low UE maximum power; operating in FR2 or higher frequency bands, where propagation loss is high and there may be fewer interference issues, etc. Furthermore, if all UEs communicate at their strongest transmission power, they may cause more interference to ongoing UL transmissions in other cells, and worse, may cause more interference to ongoing DL transmissions in other cells.

[0032] At the gNB, without such auxiliary information or indication of appropriate UL power for the configuration set, it may be impossible to effectively optimize total UE power consumption and improve UE battery life for a given QoS, or optimize UE power configuration by taking into account its power consumption impact and system-level aspects.

[0033] In example scenarios, a ratio can be provided to evaluate UE power consumption. For instance, the following expression could be considered:

[0034] ( linear ) In this example, the PAE can depend on the selected Tx power. The above formula takes into account both the first UL power configuration and the second UL power configuration (by...). and The power consumption ratio between (represented by PAE). PAE is the power-added efficiency of a PA, defined as... Of which, PA output power UL power and Where G is the PA gain. Using the above equation, the power consumption ratio R can be derived, where k is the first UL power ( ) and second UL power ( The linear power ratio between the first and second UL power. Additionally, k can be >1 or <1 (i.e., the power difference between the first and second UL power in dB can be positive or negative). Although the above example is about PUSCH, it can also be applied to any UL transmission.

[0035] For a first UL output power of 10dBm, the PAE can be 2.5%, while for a second UL output power of 22dBm (linear k=16), the PAE can be 30%. Therefore, the linear ratio of power consumption between the first and second UL power configurations can be: , where PAE=30%=>R=1.33.

[0036] In other words, with a 16-fold increase in Tx power, UE power consumption will increase by 33%, resulting in significant interference. Furthermore, the UE may experience increased heat generation and battery issues. Therefore, if there is no new data to transmit, or if QoS is already met at lower power and with less interference, this may not be necessary.

[0037] The exemplary embodiments of the present invention address at least the following problems: How can the gNB and UE coordinate to minimize UE power consumption and extend battery life, while considering QoS requirements, system aspects, and without disclosing potentially confidential UE information? The solutions proposed according to exemplary embodiments of the present invention address at least the aforementioned problems present in the standards at the time of filing of this application.

[0053] As similarly indicated above, the solutions proposed according to exemplary embodiments of the invention address at least the aforementioned problems present in the standards at the time of filing of this application.

[0054] Given the drawbacks of NW power configuration without PA efficiency or consumption considerations, certain example embodiments can provide a way for the gNB and UE to coordinate with each other in an effort to minimize UE power consumption to save UE power and battery life. In some example embodiments, the network can consider system aspects (e.g., intra-cell / inter-cell interference, network / cell capacity or spectrum efficiency, network / cell power consumption, network / cell load, current and other UE coverage or throughput or latency impact, etc.) and quality of service during coordination between the UE and gNB without disclosing potentially confidential UE information to the gNB.

[0055] In view of the above example scenarios, according to certain example embodiments, when the NW has auxiliary information indicating an appropriate UL transmission power for power saving under a predetermined set of configurations, or when the UE is allowed to adjust its UL transmission power within a predetermined range taking into account system aspects such as interference management based on its PA efficiency (e.g., using self-power tuning parameters), a third power configuration determined at least in part based on the UE PA power consumption (e.g., determined as an appropriate UL power at the UE, or determined at the NW based on the UE's indication of the appropriate UL power) can be 16 dBm (relative to a first UL power of 10 dBm, k=4), wherein the PAE at the third UL power is 12.5%.

[0056] Therefore, the relative power consumption between the first and third transmission powers (with the first transmission power as the reference and its consumption as the denominator) can be expressed as R=4. 2.5 / 12.5 = 0.8. This means the relative UE power consumption for the two configurations is R = 4. 2.5 / 12.5=0.8, and the UE power consumption is 20% less, while using an output power that is 4 times higher than the first UL power (e.g., 10dBm) (e.g., 16dBm) to transmit more data or avoid potential Hybrid Automatic Repeat Request (HARQ) / repetition delay.

[0057] In this invention, a method according to an exemplary embodiment of the invention is proposed for allowing a UE to save more power while taking into account system constraints (e.g., interference management), potentially reducing latency and / or increasing throughput.

[0058] The proposed method can be viewed as UE-centric self-power optimization with NW control to minimize the burden at the NW while maintaining complete control over the UE Tx power at the NW.

[0059] According to an exemplary embodiment of the present invention, the gNB will determine / indicate the UL configuration that meets the QoS requirements of the UE and control the initial UE Tx power, and then the UE will follow a reactive approach to optimize its power consumption.

[0060] At a high level, two of the key aspects include (more specific details will be disclosed below): 1. The UE determines the optimal operating power (or appropriate UL power) for at least one of the configured / scheduled uplink transmissions. NW can pre-indicate or configure upper limit thresholds or limits(s) that can take into account / reflect system aspects (e.g., interference management). This allows the UE to directly adjust its UL power within a range (corresponding to an upper threshold or limit), i.e., by adding the UE self-tuning power parameter within the NW indicator limit to equation (1), as shown in the new equation (2). The self-tuning parameter (value) is determined by the UE in a way that optimizes its power consumption (i.e., in terms of battery life, power saving, etc.):

[0061] 2. The UE may, for example, implicitly or indirectly (e.g., using a scaling factor for the configuration parameters in P_PUSCH equation (1)) indicate its preferred output power or appropriate UL power (within or outside the range indicated by NW) for the purpose of optimizing power consumption, or for example as Figure 5 The diagram explicitly indicates this as a power-based parameter.

[0062] According to an exemplary embodiment of the invention, the NW can then consider auxiliary information such as appropriate UL power for the UE, system-level aspects, and UL interference management, and determine / indicate new Tx power (e.g., TPC, additional UE margin). The NW can save this auxiliary information for future UL scheduling.

[0063] According to an exemplary embodiment of the present invention, the UL transmission power can be the power determined by the UE based on the UL power control formula. According to an exemplary embodiment of the present invention, the self-tuning power (e.g., beta) used in claim 8 can be a power parameter determined by the UE based on power amplifier efficiency or power consumption, and / or the appropriate UL power for power saving can be determined by the UE based on the UL configuration set and power amplifier efficiency or power consumption.

[0064] Some key steps of the exemplary embodiments of the present invention consider different possible methods to allow UE power savings.

[0065] For example, these steps may include the following operations: 1. UE capability indications related to self-power optimization and appropriate UL Tx power indications. 2. NW can request auxiliary information. 3. The NW can determine and indicate to the UE an acceptable UL power limit threshold (or range) considering system aspects (e.g., interference management, etc.): NW can adjust (multiple) thresholds at high or low frequencies based on system factors, cell load, etc. This indication can be UE-specific, cell-specific, or for a group of UEs (e.g., RedCap, IoT, etc.), and can be interpreted as the maximum power change relative to the currently configured power. 4. The UE determines the optimal Tx output power (appropriate UL power) for a given UL configuration set (M_RB, MCS, etc.): If the NW indicates a threshold or range (NW-controlled UE self-power tuning) in step 3 above, the UE can adjust its UL power as follows:

[0066] The additional term in the above equation These are UE self-power tuning parameters for UE self-power optimization, defined by a threshold or range indicated by NW, to take into account system aspects (e.g., interference management): or ,in It can have any value, even negative.

[0067] In this embodiment, according to an exemplary embodiment of the present invention, the UE determines the optimal [condition] within the defined boundaries. It can be immediately applied to UL transmissions and / or indicated to NW so that NW can consider adjusting UL configuration / scheduling or confirm it via TPC.

[0068] Additional or alternative ground, UE implicit ground (or explicit ground) indicates its appropriate UL power (recommended / preferred output power): This indication can be shown in the new PHR report for power savings, where the new preferred power margin field is located. Based on (1) And relative to Instead (This option allows for finer granularity with a finite number of bits), or can be directly indicated as an absolute value. (Appropriate UL power), or X independent of Pcmax from the current And PL, but still depends on the current scheduling due to Pcmax dependency (e.g., MPR, such as using PUSCH but without restrictions), or the value relative to the power threshold indicated by NW (if any).

[0069] Note that if NW indicates a threshold / range, then It can be equal to (i.e., defined by NW to take into account system aspects) and therefore other possible indications (X or The settings are adjusted accordingly. Otherwise, It may not be bounded, and NW considers system aspects and indicates UL power in the next step.

[0070] Such information can be sent in a new dedicated PHR for UE power, or alternated with a legacy 5G NR PHR, or sent as a standalone PHR for UE power saving, or sent in conjunction with a legacy PHR by adding new(s) fields(s). In a separate case, the power saving PHR report can be sent by reusing the virtual-PHR along with the associated reporting conditions and triggers.

[0071] The power saving PHR report can be limited to a specific UE (RedCap, IoT, or when the UE is in low battery mode, etc.), and therefore can be conditional on certain use cases (e.g., low power UE operating in a small BWP, specific power levels (e.g., excluding PC1 for FWA)).

[0072] The report can be triggered non-periodicly, or based on conditions such as thresholds: (i.e., if the current power is far from the optimal power), or after the BWP is switched to a predetermined BWP set or size, or in (1) the UL configuration update affects After a specific time period / timer, etc. Alternatively or additionally, the UE may use a few bits, which can be considered as the recommended TPC, to more dynamically indicate its preferred power adjustment state or self-power tuning parameters in the uplink control information (e.g., ).

[0073] Alternatively, the UE may implicitly indicate the appropriate UL transmission power by the scaling factor of the parameter involved in the P_PUSCH equation (e.g., the scaling factor assigned by the PRB, etc.).

[0074] The aforementioned indications from the UE can be configured to be transmitted per cell / CC or multiple cell / CCs, per UL or multiple (overlapping) ULs, or per TRP (transmit-receive point).

[0075] According to an exemplary embodiment of the present invention, NW determines and indicates a new UL scheduling or power configuration: The UL power tuning value is determined by the TPC command (NW and explicitly indicated). or By updating the PRB allocation, MCS, or other parameters in the P_PUSCH formula (the UL power tuning value determined by NW and implicitly indicated).

[0076] According to an exemplary embodiment of the invention, after NW confirmation, the UE adjusts its power for the next(s) UL transmission(s) using the current P_PUSCH, or adjusts its power using the new P_PUSCH in (2) without NW confirmation when it is within the allowable power range indicated by the NW. Note that this example takes into account the PUSCH according to the exemplary embodiment of the invention, but it is also applicable to any UL transmission.

[0077] Different UE-centric self-power optimization methods for NW control can be derived based on subsets of the above operations.

[0079] like Figure 6 As shown in box 610, the communication network's gNB 12 / 13 schedules uplink (UL) transmissions and sends UL authorizations to the UE. The communication network can indicate values ​​for permissible UL power variation thresholds and / or ranges for new parameters in the power control equation, taking into account system aspects (e.g., interference). Figure 6 As shown in box 620, UE 10 receives a configuration and determines the preferred or appropriate power based at least in part on the current scheduling and the obtained configuration. Figure 6 As shown in box 640, UE 10 performs at least one of the following: UE 10 determines the UL power based at least on the indicated UL power change threshold and / or range and the current UL scheduling configuration; and / or UE 10 reports the determined auxiliary information to the communication network, such as an indication value of the preferred output power for the current UL configuration and / or scheduling. Figure 6 As shown in box 650, the gNB 12 / 13 of the communication network determines a new power configuration and / or a new UL scheduling based on auxiliary information reported by the UE (if any), while taking into account system-level and / or gNB and / or cell constraints, such as DTx / DRX, cell load and / or interference management. Figure 6 As shown in step 660, the gNB 12 / 13 of the communication network can indicate new UL scheduling and / or UL power, such as TPC commands, at least based on the indicated auxiliary information.
