[0040] In a wireless communications system, a UE and an NE (e.g., a base station, gNB) may support wireless communication (e.g., reception and / or transmission of wireless communication) using time-frequency resources. As part of using time-frequency resources, UEs can support different power classes for wireless communication. Power classes can represent different levels of transmit power that a UE can use for data transmission, and higher power classes may support improved signal strength and extended range in comparison with lower power classes. Higher power classes can also utilize dual active transmit modes, and employ multiple transmit chains to achieve increased output power levels.

[0041] While dual transmit configurations can increase wireless coverage and network performance, such configurations can also present challenges related to power consumption and thermal management in UEs. Operating multiple transmit chains simultaneously may cause higher current draw and increased heat generation compared to single transmit configurations, which can impact battery life and potentially lead to thermal constraints in UEs. To address power and thermal issues that may occur in higher power classes, UEs may implement various mitigation techniques, which can include reducing transmit power, adjusting bandwidth allocation, or modifying antenna configurations. However, such mitigation techniques may be performed autonomously by a UE and may not align with network configurations or optimize overall system performance.

[0042] Some wireless communications systems utilize communication protocols between UEs and wireless networks (e.g., NEs) to enable more accurate and coordinated management of UE capabilities and network resources. Such protocols can attempt to balance the goals of maximizing radio link performance, optimizing battery life, and maintaining safe operating temperatures acrossAttorney Ref. No. SMM920240293-WO-PCTLenovo Ref. No. SMM920240293-WO-PCT7a diverse range of usage scenarios and environmental conditions. Some wireless communication systems use UAI information elements to enable UEs to request network assistance.

[0043] Aspects of the present disclosure are described in the context of a wireless communications system, and include implementations that provide a power class UAI for UEs to indicate to NEs an indication of power class (e.g., power class reduction) to reduce power (e.g., current) consumption or reduce heat production at the UEs. In implementations, a UE can use different UE state information to determine UAI to communicate in power saving scenarios, such as UE power modes (e.g., a battery saver mode, user selected power saving modes), battery state (e.g., low battery charge conditions), application parameters for UL and DL, emergency-related communications, etc. Based on such UE state information, a UE can communicate UAI to an NE to request assistance associated with power saving, such as UAI requesting power class reduction or other power reductions that may assist the UE in reducing UE power output.

[0044] In implementations, a UE can use different UE state information to determine UAI to communicate in thermal mitigation scenarios, such as based on UE skin temperature, application parameters for UL and DL, emergency-related communications, etc. UE skin temperature can refer to the temperature of an outer surface of a UE, such as an outer surface of a UE chassis and / or a UE case. Based on such UE state information, a UE can communicate UAI to an NE to request assistance associated with thermal mitigation, such as UAI requesting power class reduction or other power reductions that may assist the UE in reducing UE temperature.

[0045] By performing the described techniques, a device in a wireless communications system (e.g., a UE) can reduce power consumption and reduce heat output, which can conserve battery life and prevent user discomfort and / or injury due to excessive device heat output.

[0046] Reference is made herein to communicating data or information, such as signaling communication resources and / or communications that are transmitted or received between devices. It is to be appreciated that other terms may be used interchangeably with communicating, such as signaling, transmitting, receiving, outputting, forwarding, retrieving, obtaining, and so forth.

[0047] Aspects of the present disclosure are described in the context of a wireless communications system.Attorney Ref. No. SMM920240293-WO-PCTLenovo Ref. No. SMM920240293-WO-PCT8

[0048] Figure 1 illustrates an example of a wireless communications system 100 in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more NEs 102, one or more UEs 104, and a core network (CN) 106. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE network or an LTE- Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a NR network, such as a 5G network, a 5G-Advanced (5G-A) network, or a 5G ultrawideband (5G-UWB) network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20. The wireless communications system 100 may support radio access technologies beyond 5G, for example, 6G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA), frequency division multiple access (FDMA), or code division multiple access (CDMA), etc.

[0049] The one or more NEs 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the NEs 102 described herein may be or include or may be referred to as a network node, a base station, an access point (AP), a network element, a network function, a network entity, a radio access network (RAN), a NodeB, an eNodeB (eNB), a next-generation NodeB (gNB), or other suitable terminology. An NE 102 and a UE 104 may communicate via a communication link, which may be a wireless or wired connection. For example, an NE 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface.

[0050] An NE 102 may provide a geographic coverage area for which the NE 102 may support services for one or more UEs 104 within the geographic coverage area. For example, an NE 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc.) according to one or multiple radio access technologies. In some implementations, an NE 102 may be moveable, for example, a satellite associated with a non-terrestrial network (NTN). In some implementations, different geographic coverage areas associated with the same or different radio access technologies may overlap, but the different geographic coverage areas may be associated with different NE 102.Attorney Ref. No. SMM920240293-WO-PCTLenovo Ref. No. SMM920240293-WO-PCT9

[0051] The one or more UEs 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a remote unit, a mobile device, a wireless device, a remote device, a subscriber device, a transmitter device, a receiver device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an Internet-of-Things (loT) device, an Internet-of-Everything (loE) device, or machine-type communication (MTC) device, among other examples.

[0052] A UE 104 may be able to support wireless communication directly with other UEs 104 over a communication link. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link may be referred to as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.

[0053] An NE 102 may support communications with the CN 106, or with another NE 102, or both. For example, an NE 102 may interface with other NE 102 or the CN 106 through one or more backhaul links (e.g., SI, N2, N6, or other network interface). In some implementations, the NE 102 may communicate with each other directly. In some other implementations, the NE 102 may communicate with each other indirectly (e.g., via the CN 106). In some implementations, one or more NEs 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC). An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as radio heads, smart radio heads, or transmission-reception points (TRPs).

[0054] The CN 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The CN 106 may be an evolved packet core (EPC), or a 5G core (5GC), which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management Attorney Ref. No. SMM920240293-WO-PCTLenovo Ref. No. SMM920240293-WO-PCT10(e.g., data bearers, signal bearers, etc.) for the one or more UEs 104 served by the one or more NEs 102 associated with the CN 106.

[0055] The CN 106 may communicate with a packet data network over one or more backhaul links (e.g., via an SI, N2, N6, or other network interface). The packet data network may include an application server. In some implementations, one or more UEs 104 may communicate with the application server. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the CN 106 via an NE 102. The CN 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server using the established session (e.g., the established PDU session). The PDU session may be an example of a logical connection between the UE 104 and the CN 106 (e.g., one or more network functions of the CN 106).

[0056] In the wireless communications system 100, the NEs 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers)) to perform various operations (e.g., wireless communications). In some implementations, the NEs 102 and the UEs 104 may support different resource structures. For example, the NEs 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the NEs 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the NEs 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures). The NEs 102 and the UEs 104 may support various frame structures based on one or more numerologies.

[0057] One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., / r=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., / r=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., / r=l) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., / r=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., / r=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifthAttorney Ref. No. SMM920240293-WO-PCTLenovo Ref. No. SMM920240293-WO-PCT11numerology (e.g., / r=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.

[0058] A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames). Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.

[0059] Additionally, or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., / r=0, / =l , / r=2, / r=3, / r=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot may include a number (e.g., quantity) of symbols (e.g., OFDM symbols). In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing), a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., / r=0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.

[0060] In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (410 MHz - 7.125 GHz), FR2 (24.25 GHz - 52.6 GHz), FR3 (7.125 GHz - 24.25 GHz), FR4 (52.6 GHz - 114.25 GHz), FR4a or FR4-1 (52.6 GHz - 71 GHz), and FR5 (114.25 GHz - 300 GHz). In some implementations, the NEs 102 and the UEs 104 may perform wireless communications over one or Attorney Ref. No. SMM920240293-WO-PCTLenovo Ref. No. SMM920240293-WO-PCT12more of the operating frequency bands. In some implementations, FR1 may be used by the NEs 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data). In some implementations, FR2 may be used by the NEs 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.

[0061] FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies). For example, FR1 may be associated with a first numerology (e.g., / r=0), which includes 15 kHz subcarrier spacing; a second numerology (e.g., / r=l), which includes 30 kHz subcarrier spacing; and a third numerology (e.g., / r=2), which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies). For example, FR2 may be associated with a third numerology (e.g., / r=2), which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., / r=3), which includes 120 kHz subcarrier spacing.

[0062] According to implementations, one or more of the NEs 102 and the UEs 104 are operable to implement various aspects of the techniques described with reference to the present disclosure. For example, a UE 104 determines that one or more of a UE power condition or a UE thermal condition occurs, and transmits to an NE 102 a first assistance request for power class reduction based at least in part on one or more of the UE power condition or the UE thermal condition. The first assistance request may request a reduction in a maximum power class used by the NE 102 for wireless communication with the UE 104.

[0063] An NE 102 (e.g., a base station, gNB) receives, from a UE 104, a first assistance request for power class reduction based at least in part on one or more of a UE power condition or a UE thermal condition, and performs a power class reduction operation based at least in part on the first assistance request. The power class reduction operation can include reducing, by the NE 102, a maximum power class used by the NE 102 for wireless communication with the UE 104.

[0064] Reference is made herein to communicating data or information, such as signaling communication resources and / or communications that are transmitted or received between devices. It is to be appreciated that other terms may be used interchangeably with communicating, such as signaling, transmitting, receiving, outputting, forwarding, retrieving, obtaining, and so forth.Attorney Ref.

[0065] Figure 2 illustrates an example system 200 in accordance with aspects of the present disclosure. The system 200 includes one or more downlink channels 202 and one or more uplink channels 204 available for wireless communication between an NE 102 and a UE 104. The UE 104 can monitor various device states 206, such as power states, thermal states (e.g., UE temperature), etc. In implementations, the UE 104 may detect a power condition 208 where the UE 104 may request assistance to reduce power (e.g., current) consumption of the UE 104. In an example, the power condition 208 can include activation of a power saving mode at the UE 104. A user and / or device functionality, for example, can trigger a power saving mode of the UE 104, such as a battery conservation mode (e.g., “Eco” mode), a battery saver mode, etc. As another example, the power condition 208 can be based on a low battery level of the UE 104, e.g., a battery level below a battery charge threshold.

[0066] Based on the power condition 208, the UE 104 can communicate (transmit, send) a UAI 212 to the NE 102 requesting one or more power reduction procedures, e.g., a power class reduction. As further detailed herein, the UAI 212 may include a specific power class reduction, such as power class reduction associated with uplink communication from the UE 104 to the NE 102. Some conditions may occur where the UE 104 does not request power class reduction based on the power condition 208, such as where the UE 104 performs an emergency communication (e.g., an emergency call, an emergency message), where an application of the UE 104 specifies an UL parameter (e.g., a minimum UL throughput for the UE) for uplink transmission by the UE 104, or where an application of the UE 104 specifies a DL parameter, e.g., a minimum DL throughput for the UE.

[0067] In implementations, the UE 104 may detect a thermal condition 210, such as based on a temperature (e.g., a skin temperature) of the UE 104 meeting (e.g., exceeding) a temperature threshold. The thermal condition 210, for example, can occur when the skin temperature of the UE 104 meets a minimum temperature threshold for initiating thermal mitigation, but does not meet a critical temperature threshold for device safety. Based on the thermal condition 210, the UE 104 can communicate (transmit, send) a UAI 212 to the NE 102 requesting one or more power reduction procedures, e.g., a power class reduction. As further detailed herein, and based on the thermal condition 210, the UAI 212 may include specific power class reduction, such as power class reduction associated with uplink communication from the UE 104 to the NE 102. Some conditionsAttorney Ref. No. SMM920240293-WO-PCTLenovo Ref. No. SMM920240293-WO-PCT14may occur where the UE 104 does not request power class reduction based on the thermal condition 210, such as where the UE 104 performs an emergency communication (e.g., an emergency call, an emergency message), where an application of the UE 104 specifies a particular uplink parameter (e.g., a minimum uplink throughput) for uplink transmission by the UE 104, or where an application of the UE 104 specifies a DL parameter, e.g., a minimum DL throughput for the UE.

[0068] Where the UE 104 communicates the UAI 212 to the NE 102 requesting power class reduction, the NE 102 may perform power class reduction 214 for wireless communication with the UE 104. The power class reduction 214, for example, includes uplink communication over the one or more uplink channels 204.

If the power condition occurs (“Yes”), at 306 the method may include determining whether a link quality of the UE meets a threshold link quality. The threshold link quality may be measured in various ways, such as received signal strength indication (RSSI), signal-to-noise ratio (SNR), signal-to-interference-plus-noise ratio (SINR), etc. If the link quality of the UE meets the threshold link quality (“Yes”), at 308 the method may include evaluating application parameters. The application parameters, for example, may specify a minimum UL throughput and / or a minimum DL throughput associated with the UE.

If at 316 neither UL nor DL are indicated as a priority, at 322 the method may include configuring a UAI setting for power reduction for either or both of UL communication or DL communication.

[0071] At 324, the method may include determining a mitigation level based on UE battery level. The mitigation level may specify whether power class reduction is to be applied to UL. For example, where UE battery level is below a threshold, multiple mitigation levels may be applied. At 326, the method may include communicating UAI information. The UE may communicate the UAI information to a NE. In implementations, the UAI information may request power reduction for UL and / or DL. The UAI may include a request for power class reduction based on the determined mitigation level and may request power class reduction for UL.

If at 310 an emergency condition occurs (“Yes”), at 328 the method may include terminating UAI and at 326 communicating UAI information to stop power reduction associated with the UE, e.g., power class reduction for the UE.
