Technical Field

[0003] The following discussion relates to wireless communications, including power control enhancements for uplink transmission multiplexing. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems, such as Long Term Evolution (LTE) systems, improved LTE (LTE-A) systems, or LTE-A Pro systems, and fifth-generation (5G) systems, which may be called New Radio (NR) systems. These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each of which simultaneously supports communication for multiple communication devices, which may also be referred to as User Equipment (UE).

[0005] Some wireless systems support the multiplexing of uplink transmissions. In some cases, it may be desirable to improve the efficiency of multiplexed uplink transmissions. Summary of the Invention

[0006] The described technology relates to improved methods, systems, devices, and apparatuses for power control prioritization in wireless communications. In summary, the described technology provides a user equipment (UE) for determining power control prioritization in wireless communications. In some cases, the UE may perform multiplexed transmissions on a first uplink carrier. The multiplexed transmissions may include a first uplink transmission multiplexed with a second uplink transmission. The first and second uplink transmissions may have different priorities. The UE may assign a first priority level to the multiplexed transmissions based on the priority content (e.g., a highest priority content) of the first and second uplink transmissions. Therefore, the priority content (whether it is the content of the first or second uplink transmission) determines the overall priority of the multiplexed transmissions.

[0007] In some cases, the UE can assign a second priority level to the third uplink transmission on the second component carrier based on the content of the third uplink transmission. In some cases, at least a portion of the third uplink transmission can overlap temporally with the multiplexed transmission. In some cases, the UE can perform the multiplexed transmission on the first component carrier with a first transmit power and the third uplink transmission on the second component carrier with a second transmit power. In some cases, the UE can determine the first transmit power based on the first priority level and the second transmit power based on the second priority level. If the combined total transmit power of the first and second uplink carriers would otherwise exceed a defined power limit, the transmit power calculated for the first and second uplink carriers can be reduced based on the corresponding priority levels of the uplink multiplexed transmission and the third uplink transmission, respectively. For example, if the first priority level exceeds the second priority level, the second transmit power can be reduced by a larger amount compared to the first transmit power, and vice versa.

[0008] A method for power control prioritization in wireless communication performed by a user equipment (UE) is described. The method may include: assigning a first priority level to a multiplexed transmission on a first component carrier, the multiplexed transmission including a first uplink transmission multiplexed with a second uplink transmission, wherein the first priority level assigned to the multiplexed transmission is based on the priority of the content of the first uplink transmission and the second uplink transmission; assigning a second priority level to a third uplink transmission on a second component carrier based on the content of the third uplink transmission, wherein the third uplink transmission overlaps temporally with the multiplexed transmission; and performing the multiplexed transmission on the first component carrier with a first transmit power and performing the third uplink transmission on the second component carrier with a second transmit power, wherein the first transmit power and the second transmit power are based on the first priority level and the second priority level, respectively.

[0009] An apparatus for power control prioritization of wireless communication performed by a UE is described. The apparatus may include a processor, a memory coupled to the processor, and instructions stored in the memory. The instructions may be executable by the processor to cause the apparatus to: assign a first priority level to a multiplexed transmission on a first component carrier, the multiplexed transmission including a first uplink transmission multiplexed with a second uplink transmission, wherein the first priority level assigned to the multiplexed transmission is based on the priority of the content of the first uplink transmission and the second uplink transmission; assign a second priority level to a third uplink transmission on a second component carrier based on the content of the third uplink transmission, wherein the third uplink transmission overlaps temporally with the multiplexed transmission; and execute the multiplexed transmission on the first component carrier with a first transmit power and execute the third uplink transmission on the second component carrier with a second transmit power, wherein the first transmit power and the second transmit power are based on the first priority level and the second priority level, respectively.

[0010] Another apparatus for power control prioritization in wireless communication performed by a UE is described. The apparatus may include: a unit for assigning a first priority level to a multiplexed transmission on a first component carrier, the multiplexed transmission including a first uplink transmission multiplexed with a second uplink transmission, wherein the first priority level assigned to the multiplexed transmission is based on the priority of the content of the first uplink transmission and the second uplink transmission; a unit for assigning a second priority level to a third uplink transmission on a second component carrier based on the content of the third uplink transmission, wherein the third uplink transmission overlaps temporally with the multiplexed transmission; and a unit for performing the multiplexed transmission on the first component carrier with a first transmit power and performing the third uplink transmission on the second component carrier with a second transmit power, wherein the first transmit power and the second transmit power are based on the first priority level and the second priority level, respectively.

[0011] A non-transitory computer-readable medium is described, storing code for power control prioritization of wireless communication performed by a UE. The code may include instructions executable by a processor to: assign a first priority level to a multiplexed transmission on a first component carrier, the multiplexed transmission including a first uplink transmission multiplexed with a second uplink transmission, wherein the first priority level assigned to the multiplexed transmission is based on the priority of the content of the first uplink transmission and the second uplink transmission; assign a second priority level to a third uplink transmission on a second component carrier based on the content of the third uplink transmission, wherein the third uplink transmission overlaps temporally with the multiplexed transmission; and execute the multiplexed transmission on the first component carrier with a first transmit power and execute the third uplink transmission on the second component carrier with a second transmit power, wherein the first transmit power and the second transmit power are based on the first priority level and the second priority level, respectively.

[0012] In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, assigning a first priority level to the multiplexed transmission may include operations, features, units, or instructions for: assigning the first priority level to a first set of symbols of the multiplexed transmission, the first set of symbols being associated with a first uplink transmission and a second uplink transmission; and assigning a third priority level to a second set of symbols of the multiplexed transmission, the second set of symbols being associated with either the first uplink transmission or the second uplink transmission.

[0013] In some examples of the methods, apparatuses and non-transitory computer-readable media described herein, performing the multiplexed transmission on the first component carrier may include operations, features, units or instructions for performing the multiplexed transmission on the first component carrier with the first transmit power for the first symbol set and with the second symbol set at a third transmit power different from the first transmit power.

[0014] In some examples of the methods, apparatuses, and non-transitory computer-readable media described herein, the first priority level or the second priority level, or both, may be determined according to a priority hierarchy. In some cases, the first priority level assigned to the multiplexed transmission is based on the highest priority of the content of the first uplink transmission and the second uplink transmission.

[0027] Figure 8 and Figure 9 A flowchart illustrating a method for supporting enhanced power control based on the examples described herein is shown. Detailed Implementation

[0028] This technology includes power control prioritization in wireless communications. Some systems may include two priority levels (e.g., low priority (LP or priority 0) and high priority (HP or priority 1) for uplink transmissions to send services with different reliability / latency requirements. In some cases, HP may refer to an uplink transmission with priority index 0, and LP may refer to an uplink transmission with priority index 1. In some cases, uplink transmissions may include HP uplink transmissions (e.g., uplink transmissions including HP content or HP payloads) and LP uplink transmissions (e.g., uplink transmissions including LP content or LP payloads). Examples of HP content may include Ultra Reliable Low Latency Communication (URLLC) services. Examples of LP content may include Enhanced Mobile Broadband (eMBB) services.

[0029] In some examples, when an LP (Level 1) transport conflicts with an HP (Level 2) transport (e.g., the time resources of the LP transport at least partially overlap with the time resources of the HP transport), the LP transport can be dropped. However, dropping a transport can lead to retransmissions and a poor user experience. Therefore, some systems can multiplex uplink transports with different priorities into a single multiplexed transport (e.g., multiplexing HP uplink transports and LP uplink transports into a single multiplexed transport). In some cases, puncturing or rate matching can be used to multiplex two uplink transports. In some cases, the coding rate can be modified to allow the transmission of two uplink transports.

[0030] In some examples, the UE can multiplex both HP content and LP content into a multiplexed transmission. In other examples, the UE can multiplex both HP uplink control information (UCI) and LP UCI into a physical uplink control channel, or multiplex HP UCI on an LP physical uplink shared channel, or multiplex LPUCI on an HP physical uplink shared channel. However, some systems lack techniques for determining the priority of multiplexed transmissions with mixed priorities relative to other uplink transmissions.

[0031] This technology enables devices to determine the priority of multiplexed transmissions relative to other uplink transmissions. In particular, this technology provides enhanced power control for HP and LP uplink transmission multiplexing.

[0032] In some examples, the UE can be configured to transmit more than one physical uplink channel on the corresponding uplink carrier. In some cases, the UE can be configured to transmit one physical uplink control channel and one physical uplink shared channel, or transmit two physical uplink control channels in the corresponding physical uplink control channel group.

[0033] In some examples, when two or more uplink transmissions are scheduled simultaneously (e.g., the symbols of the two or more uplink transmissions at least partially overlap in time), the UE can perform power prioritization to determine how much power to allocate to a first uplink transmission and how much power to allocate to a second uplink transmission. Based on this technique for power control prioritization, the priority of uplink transmissions can be determined by the priority of the content included in the uplink transmissions. Power control prioritization can be based on a power control prioritization hierarchy that indicates priorities from highest to lowest based on content characteristics (e.g., content type, etc.).

[0034] The various aspects of the subject matter described herein can be implemented to achieve one or more advantages. The described techniques can support improved transmit power control of multiplexed transmissions based on the determined uplink transmission priorities. Furthermore, the described techniques can enable the avoidance of dropped transmissions, multiple retransmissions, and failed transmissions, reduce system latency, improve the reliability of decoding high-priority uplink transmissions at the base station, and improve user experience.

[0035] The various aspects of this disclosure are first described in the context of a wireless communication system. These aspects are further illustrated by relating to a wireless communication system for power control of uplink transmission multiplexing, and are described with reference to such a system. The various aspects of this disclosure are further illustrated by apparatus diagrams, system diagrams, and flowcharts relating to power control of uplink transmission multiplexing, and are described with reference to these diagrams.

[0036] Figure 1An example of a wireless communication system 100 supporting power control for uplink transmission multiplexing, according to the examples described herein, is shown. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an improved LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices, or any combination thereof.

[0037] Base station 105 can be distributed throughout a geographical area to form wireless communication system 100, and can be devices of different forms or with different capabilities. Base station 105 and UE 115 can communicate wirelessly via one or more communication links 125. Base station 105 can provide coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 on coverage area 110. Coverage area 110 can be an example of a geographical area where base station 105 and UE 115 can support signal transmission according to one or more radio access technologies.

[0038] UE 115 can be distributed within the coverage area 110 of the wireless communication system 100, and at least one UE 115 can be stationary, mobile, or both at different times. UE 115 can be a device of different forms or with different capabilities. Figure 1 Some example UE 115s are shown in the document. The UE 115 described herein may be able to communicate with various types of devices, such as other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as... Figure 1 As shown.

[0039] Base station 105 can communicate with core network 130, communicate with each other, or perform both operations. For example, base station 105 can be connected to core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate directly (e.g., directly between base stations 105) on backhaul links 120 (e.g., via X2, Xn, or other interfaces), or indirectly (e.g., via core network 130), or perform both operations. In some examples, backhaul link 120 can be or includes one or more radio links.

[0040] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, node B, evolved node B (eNodeB, eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home evolved node B, or other suitable terms.

[0041] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, and other examples. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, and other examples, which may be implemented in various items such as appliances, vehicles, meters, and other examples.

[0042] The UE 115 described in this document may be able to communicate with various types of devices, such as other UE 115s that can sometimes act as repeaters, as well as base station 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, and other examples, such as... Figure 1 As shown.

[0043] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). At least one physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0044] In some examples (e.g., in a carrier aggregation configuration), carriers may also have acquisition or control signaling that coordinates operation against other carriers. Carriers may be associated with frequency channels (e.g., Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be positioned according to a channel grid for discovery by UE 115. Carriers may operate in standalone mode, where UE 115 can initiate acquisition and connection via a carrier, or in non-standalone mode, where different carriers (e.g., the same or different radio access technologies) are used to anchor the connection.

[0045] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The carrier may carry downlink or uplink communication (e.g., in FDD mode) or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0046] A carrier may be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one of a number of defined bandwidths for a specific radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) may have a hardware configuration that supports communication over a specific carrier bandwidth, or may be configurable to support communication over a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, the served UE 115 may be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0047] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as Orthogonal Frequency Division Multiplexing (OFDM) or Discrete Fourier Transform Spread Spectrum OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by the resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements UE 115 receives and the higher the order of the modulation scheme, the higher the data rate can be for UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity used for communication with UE 115.

[0048] One or more digital schemes (numerologies) can be supported for a carrier, where the digital scheme may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier can be divided into one or more BWPs with the same or different digital schemes. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and communication for UE 115 can be restricted to one or more active BWPs.

[0049] It can be expressed in a basic unit of time (which can be, for example, T). s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N f The time interval for base station 105 or UE 115 can be represented as a multiple of the maximum supported Discrete Fourier Transform (DFT) size. The time interval for communication resources can be organized according to radio frames with a specified duration (e.g., 10 milliseconds (ms)). Radio frames can be identified by their System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0050] A frame may include multiple consecutively numbered subframes or time slots, and the subframes or time slots may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and subframes may be further divided into a number of time slots. Alternatively, a frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. A time slot may include a number of symbol periods (e.g., this depends on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, a time slot may be further divided into multiple micro-time slots containing one or more symbols. Excluding the cyclic prefix, a symbol period may contain one or more (e.g., N) symbols. f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0051] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Alternatively or additionally, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst form of a shortened TTI (sTTI)).

[0052] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by the number of symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a group of UEs 115. For example, one or more of the UEs 115 can monitor or search for control regions against control information based on one or more search space sets, and the search space sets can include one or more control channel candidates arranged in a cascaded manner at one or more aggregation levels. The aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set used to send control information to a specific UE 115.

[0053] In some examples, base station 105 may be mobile, and therefore provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0054] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support URLLC or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private or group communication and may be supported by one or more mission-critical services (such as Mission-Critical Push-to-Talk (MCPTT), Mission-Critical Video (MCVideo), or Mission-Critical Data (MCData)). Support for mission-critical functions may include service prioritization, and mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0055] In some examples, UE 115 may also be able to communicate directly with other UE 115s on a device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UEs 115s utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UEs 115s in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, groups of UEs 115s communicating via D2D communication may utilize a one-to-many (1:M) system, wherein at least one UE 115 transmits to one or more other (e.g., each other) UEs 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115s without involving base station 105.

[0056] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function unit (AMF)) managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function unit (UPF)) routing packets to or interconnecting with external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to IP services 150 for one or more network operators. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0057] Some network devices (e.g., base station 105) may include sub-components such as access network entity 140, which may be an example of an access node controller (ANC). Access network entity 140 (e.g., each access network entity 140) may communicate with UE 115 through one or more other access network transport entities 145 (which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP)). Access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of access network entity 140 (e.g., each access network entity 140) or base station 105 may be distributed across individual network devices (e.g., radio headends and ANCs) or incorporated into a single network device (e.g., base station 105).

[0058] Wireless communication system 100 can operate using one or more frequency bands (typically in the range of 300 MHz to 300 GHz). The region from 300 MHz to 3 GHz is typically referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves can be sufficiently permeable to penetrate structures for use in macrocells to provide service to UE 115 located indoors. Transmission of UHF waves can be associated with smaller antennas and shorter distances (e.g., less than 100 km) compared to the transmission of smaller frequencies and longer waves in the lower 300 MHz portion of the spectrum, such as the High Frequency (HF) or Very High Frequency (VHF) portions.

[0059] Wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio frequency spectrum bands, devices (such as base station 105 and UE 115) can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands can be based on carrier aggregation configurations that combine component carriers operating in licensed frequency bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and other examples.

[0060] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operation or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array having a number of rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.

[0061] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to form or guide an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating relative to a specific orientation of the antenna array experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with the transmitting or receiving device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).

[0062] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correct data reception on communication link 125. HARQ can include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal and noise conditions). In some examples, the device can support same-slot HARQ feedback, where the device can provide HARQ feedback for data received in a previous symbol within a specific time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0063] In some examples, UE (e.g., Figure 1The UE (115) can perform power control prioritization for wireless communication. In some cases, power control prioritization by the UE may include assigning a first priority to a multiplexed transmission on a first component carrier. In some cases, the multiplexed transmission may include a first uplink transmission multiplexed with a second uplink transmission. In some cases, the first priority assigned to the multiplexed transmission is based on the priority of the content of the first and second uplink transmissions (e.g., the highest priority content). In some cases, the UE may assign a second priority to a third uplink transmission on a second component carrier based on the content of the third uplink transmission. In some cases, the third uplink transmission at least partially overlaps with the multiplexed transmission in time. In some cases, the UE may perform the multiplexed transmission on the first component carrier with a first transmit power and the third uplink transmission on the second component carrier with a second transmit power. In some cases, the first transmit power and the second transmit power are based on a first priority level and a second priority level, respectively. In some cases, the UE may prioritize the transmission to a base station (e.g., to...). Figure 1 The base station 105) sends a multiplexed transmission or a third uplink transmission, or both.

[0064] Figure 2 An example of a wireless communication subsystem 200 supporting power control for uplink transmission multiplexing, as described herein, is shown.

[0065] As shown in the figure, the wireless communication subsystem 200 may include UE 115-a and base station 105-a, which may be as described herein. Figure 1 Examples of UE 115 or base station 105 are described. The wireless communication subsystem 200 may also include uplink 205 and uplink 210. In some cases, the wireless communication subsystem 200 may also include a downlink. Base station 105-a may use the downlink to transmit control and / or data information to UE 115-a. And UE 115-a may use uplink 205 or uplink 210 or both to transmit control and / or data information to base station 105-a. In some cases, the downlink may use different time and / or frequency resources than uplink 205 or uplink 210 or both.

[0066] In some examples, UE 115-a can perform power control prioritization for wireless communication between UE 115-a and base station 105-a. In some cases, UE 115-a can determine the priority of the content carried on each uplink transmission, and then determine the transmission power for each uplink transmission based on the corresponding determined priority.

[0067] In some examples, UE 115-a performing power control prioritization may include UE 115-a assigning a first priority level to the multiplexed transmission 215 on the first component carrier of uplink 205. In some cases, the multiplexed transmission 215 may include a first uplink transmission multiplexed with a second uplink transmission. In some cases, the first priority level assigned to the multiplexed transmission 215 may be based on the content of the first uplink transmission and the second uplink transmission with the highest priority content. In some cases, the content of the first uplink transmission may have the highest priority content. Therefore, the content of the first uplink transmission determines the priority level assigned to the multiplexed transmission 215. In some cases, the content of the second uplink transmission may have the highest priority content. Therefore, the content of the second uplink transmission determines the priority level assigned to the multiplexed transmission 215.

[0068] In some cases, UE 115-a may determine that the third uplink transmission 220 overlaps at least partially with the multiplexed transmission 215 in time. In some cases, based on the determined overlap, UE 115-a may determine and assign a first priority level for the multiplexed transmission 215, and determine and assign a second priority level for the third uplink transmission 220. In some cases, UE 115-a may assign a second priority level to the third uplink transmission 220 on the second component carrier of uplink 210 based on the content of the third uplink transmission 220 (e.g., based on the content of the third uplink transmission 220 relative to the content of the multiplexed transmission 215).

[0069] In some cases, UE 115-a can perform a multiplexed transmission 215 on a first component carrier with a first transmit power and a third uplink transmission 220 on a second component carrier with a second transmit power. In some cases, the first transmit power can be based on a first priority level, and the second transmit power can be based on a second priority level. In some examples, the first priority level and the second priority level can be based on a power control prioritization hierarchy. As shown, UE 115-a can send the multiplexed transmission 215 to base station 105-a, or send the third uplink transmission 220 to base station 105-a, or both.

[0070] This technology improves the power efficiency of one or more devices (e.g., battery-operated devices) by prioritizing power control of wireless communications, including multiplexed transmissions. Figure 1 or Figure 2The power usage and efficiency of UE 115 (e.g., UE 115) are improved to enhance the user experience of one or more devices with longer battery life, improved quality of service, and increased data throughput.

[0071] Figure 3 An example of an environment 300 supporting power control for uplink transmission multiplexing, as described herein, is shown.

[0072] In the example shown, environment 300 may include a multiplexed transmission 305, which includes at least a first uplink transmission and a second uplink transmission, wherein at least the first uplink transmission is multiplexed with the second uplink transmission. As shown, environment 300 may also include a third uplink transmission 310.

[0073] In the example shown, the multiplexed transmission 305 may include multiple symbols (e.g., 11 symbols in the provided example), which may include various content or payloads. In some cases, the symbols may include OFDM symbols. As shown, the multiplexed transmission 305 may include a high-priority HARQ acknowledgment (HARQ-ACK) feedback 315. As shown, the HARQ-ACK feedback 315 may occupy (e.g., be carried on) symbol 1 and partially occupy symbol 3. As shown, a first demodulation reference signal (DMRS) 320-a may occupy symbol 2 of the multiplexed transmission 305, and a second DMRS 320-b may occupy symbol 8 of the multiplexed transmission 305. In the example shown, the multiplexed transmission 305 may include a low-priority physical uplink channel 325 (e.g., a low-priority physical uplink shared channel (PUSCH) or a low-priority physical uplink control channel (PUCCH) from 325-a to 325-i) occupying symbols 0, a portion of symbol 3, symbols 4 to 7, and symbols 9 to 11. In some cases, multiplexed transmission 305 can be designated as a low-priority uplink transmission. In some cases, multiplexed transmission 305 can be designated as a low-priority uplink transmission based on its content (e.g., based on low-priority physical uplink channel 325).

[0074] In the example shown, the third uplink transmission 310 may include a physical uplink channel (e.g., PUSCH or PUCCH), which may include various content or payloads. In some cases, the third uplink transmission 310 may be designated as a high-priority uplink channel. In some cases, the third uplink transmission 310 may be designated as a high-priority uplink channel based on its content.

[0075] In some examples, the uplink transmission content can be prioritized according to a power control prioritization hierarchy. In some cases, the power control prioritization hierarchy may indicate that content associated with random access channels on the primary cell has a first priority (e.g., the highest overall priority) and content associated with probe reference signal transmissions has a second priority (e.g., the lowest overall priority).

[0076] For power control prioritization, the priority of uplink transmissions can be determined by the highest priority of the content / payload included in the uplink transmission, as follows:

[0077] • High-priority HARQ-ACK, Schedule Request (SR), Link Recovery Request (LRR);

[0078] • High-priority CSI;

[0079] • High-priority uplink UL-SCH (e.g., uplink data);

[0080] • Low priority HARQ-ACK, SR, LRR;

[0081] • Low-priority Channel State Information (CSI);

[0082] • Low-priority UL-SCH (e.g., uplink data).

[0083] For example, a PUCCH with both low-priority and high-priority HARQ-ACKs can be determined to have the same priority as a high-priority PUCCH with HARQ-ACKs. In some cases, a low-priority PUSCH carrying a high-priority HARQ-ACK can be determined to have the same priority as a high-priority HARQ-ACK. In some cases, a high-priority PUSCH carrying a low-priority HARQ-ACK can be determined to have the same priority as a high-priority PUSCH without HARQ-ACKs.

[0084] In some examples, the priority hierarchy for NR uplink transmissions from highest to lowest priority can be configured as follows:

[0085] 1. Physical random access channel on the primary cell;

[0086] 2. PUCCH / PUSCH containing high-priority HARQ-ACK and / or high-priority SR and / or high-priority LRR (and may include other content, such as low-priority HARQ-ACK, low-priority CSI, etc.);

[0087] 3. PUCCH / PUSCH with high-priority CSI;

[0088] 4. No high-priority HARQ-ACK or high-priority CSI high-priority PUSCH;

[0089] 5. Low-priority PUCCH / PUSCH containing low-priority HARQ-ACK and / or low-priority SR and / or low-priority LRR; 6. Low-priority PUCCH / PUSCH with low-priority CSI.

[0090] 7. Low-priority pushes without HARQ-ACK or CSI;

[0091] 8. Detection Reference Signal (SRS) transmission.

[0092] In some examples, the power control prioritization hierarchy can indicate that content associated with a physical uplink channel that includes one or more of HARQ-ACK, or high-priority SR, or high-priority LRR (e.g., the content of multiplexed transmission 305 or the content of third uplink transmission 310) has a higher priority than content associated with a physical uplink channel that includes high-priority CSI.

[0093] In some examples, the power control prioritization hierarchy can indicate that content including a high-priority CSI has a higher priority than content associated with a high-priority physical uplink shared channel that lacks both high-priority HARQ-ACK feedback and high-priority CSI. In other examples, the power control prioritization hierarchy can indicate that content associated with a high-priority physical uplink shared channel that lacks both high-priority HARQ-ACK feedback and high-priority CSI has a higher priority than content associated with a low-priority physical uplink channel that includes one or more of the following: low-priority HARQ-ACK feedback, or low-priority SR, or low-priority LRR, or any combination thereof.

[0094] In some examples, the power control prioritization hierarchy can indicate that content associated with a low-priority physical uplink channel that includes one or more of low-priority HARQ-ACK feedback, or low-priority SR, or low-priority LRR, has a higher priority than content associated with a low-priority physical uplink channel that includes low-priority CSI. In some examples, the power control prioritization hierarchy can indicate that content associated with a low-priority physical uplink channel that includes low-priority CSI has a higher priority than content associated with a low-priority physical uplink shared channel that lacks HARQ-ACK feedback and channel state information.

[0095] In some examples, according to the power control prioritization hierarchy, a physical uplink channel with both low-priority HARQ-ACK and high-priority HARQ-ACK can be determined to have the same priority as a high-priority physical uplink channel with HARQ-ACK. According to the power control prioritization hierarchy, a low-priority physical uplink channel carrying high-priority HARQ-ACK feedback (e.g., low-priority physical uplink channel 325 of multiplexed transmission 305) can be determined to have the same priority as an uplink transmission with high-priority HARQ-ACK feedback. According to the power control prioritization hierarchy, a high-priority physical uplink channel carrying low-priority HARQ-ACK can be determined to have the same priority as a high-priority physical uplink channel without HARQ-ACK.

[0096] This technology may include UE (e.g., Figure 1 or Figure 2The UE (115) applies a power control prioritization hierarchy on a per-transmission basis. In some cases, a first uplink carrier may be associated with multiplexed transmission 305, and a second uplink carrier may be associated with a third uplink transmission 310. When the UE determines that the combined transmit power of the first and second uplink carriers will exceed a defined power limit, it may reduce the transmit power calculated for the first and second uplink carriers respectively based on the corresponding priority levels of the multiplexed transmission 305 and the third uplink transmission 310. When the UE determines that the multiplexed transmission 305 is designated as a low-priority uplink transmission and the third uplink transmission 310 is designated as a high-priority uplink channel, or that the priority of the third uplink transmission 310 exceeds the priority of the multiplexed transmission 305, the UE may reduce the transmit power of the multiplexed transmission 305 by a greater amount than the transmit power of the third uplink transmission 310. In some cases, when multiplexed transmission 305 and third uplink transmission 310 are scheduled with transmit powers P1 and P2 respectively, and the total power is greater than P_max (e.g., P1+P2>P_max), the UE may first allocate power to the higher-priority transmission until the allocated power of the higher-priority transmission reaches the corresponding scheduled power (e.g., P1 for multiplexed transmission 305 or P2 for third uplink transmission 310). The UE may then allocate the remaining power (e.g., up to P_max of the total available power) to the lower-priority transmission. In some cases, when the scheduled power of a high-priority transmission exceeds P_max, the UE may allocate power (e.g., all power) to the high-priority transmission without allocating any power to the low-priority channel (e.g., the low-priority channel may be discarded). In some cases, when the UE determines that the multiplexed transmission 305 is designated as a high-priority uplink transmission and the third uplink transmission 310 is designated as a low-priority uplink channel, or when the priority level of the multiplexed transmission 305 exceeds the priority level of the third uplink transmission 310, the UE may reduce the transmit power of the third uplink transmission 310 by a greater amount than the transmit power of the multiplexed transmission 305.

[0097] This technology may include UE (e.g., Figure 1 or Figure 2The UE (115) applies a power control prioritization hierarchy on a symbol-by-symbol basis (e.g., on a per-OFDM symbol basis). Therefore, the UE can apply a power control prioritization hierarchy to the symbols of the multiplexed transmission 305 on a symbol-by-symbol basis. For example, the UE can apply a first priority to symbol 1 based on the content of symbol 1 of the multiplexed transmission 305 (e.g., a high-priority uplink transmission), and apply a second priority, different from the first priority, to symbol 2 based on the content of symbol 2 of the multiplexed transmission 305 (e.g., a low-priority uplink transmission, etc.), and so on. In some cases, the UE can determine the priority of the content carried on each symbol and determine the transmission power for each symbol based on the corresponding determined priority. In some cases, the priority of the DMRS symbol 320 of the multiplexed transmission 305 can be equal to the priority of the highest-priority content in the multiplexed transmission 305 (e.g., the priority of DMRS 320 can be equal to the priority of HARQ-ACK feedback 315).

[0098] In some examples, priority can be determined symbol-by-symbol for a given uplink transmission. In some cases, the first group of one or more symbols of multiplexed transmission 305 may have a first priority, and the second group of one or more symbols of multiplexed transmission 305 may have a second priority different from the first priority, while multiplexed transmission 305 does not have an overall priority. Similarly, the first group of one or more symbols of third uplink transmission 310 may have a first priority, and the second group of one or more symbols of third uplink transmission 310 may have a second priority different from the first priority, while third uplink transmission 310 does not have an overall priority. Alternatively, in some cases, priority can be determined by the service type of a given uplink transmission. In some cases, multiplexed transmission 305 may be generally designated as a low-priority physical uplink channel (e.g., because multiplexed transmission 305 is associated with eMBB service), while third uplink transmission 310 may be generally designated as a high-priority physical uplink channel (e.g., because third uplink transmission 310 is associated with URLLC service). In some cases, the UE can determine the priority of the uplink transmission. In some cases, the base station can determine the priority of uplink transmissions.

[0099] In the example shown, the multiplexed transmission 305 may include high-priority content. For example, a portion of symbols 1 and 3 of the multiplexed transmission 305 includes HARQ-ACK feedback 315. Therefore, based on the content of a portion of symbols 1 and 3 carrying HARQ-ACK feedback 315, at least a portion of symbols 1 and 3 of the multiplexed transmission 305 can be designated as high priority. However, because symbols 1 to 3 of the multiplexed transmission 305 do not overlap with the third uplink transmission 310, symbols 1 to 3 in the multiplexed transmission 305 can be transmitted without determining or considering power prioritization between the multiplexed transmission 305 and the third uplink transmission 310.

[0100] In the example shown, the third uplink transmission 310 overlaps at least partially in time with the multiplexed transmission 305. As shown, the third uplink transmission 310 overlaps with symbols 4 to 11 of the multiplexed transmission 305. In some cases, the associated UE can determine that the multiplexed transmission 305 and the third uplink transmission 310 overlap on symbols 4 to 11 of the multiplexed transmission 305. Based on the determined overlap, the UE can determine that the third uplink transmission 310 is designated as a high-priority physical uplink channel. Furthermore, based on the determined overlap, the UE can determine the priority of the content of each overlapping symbol (e.g., symbols 4 to 11 of the multiplexed transmission 305). In some cases, the UE can use a power control prioritization hierarchy to determine the priority of each overlapping symbol. In some cases, the UE can assign a priority level to each overlapping symbol.

[0101] In the example shown, the UE can determine that the content of each of symbols 4 to 11 has a lower priority level than the content of the third uplink transmission 310. Therefore, the UE can prioritize the transmit power of the third uplink transmission 310 over the transmit power of symbols 4 to 11 of the multiplexed transmission 305. Thus, the third uplink transmission 310 can be prioritized over symbols 4 to 11 of the multiplexed transmission 305 for transmit power (e.g., more transmit power can be allocated to the third uplink transmission 310 on a symbol-by-symbol basis according to the corresponding priority, compared to symbols 4 to 11 of the multiplexed transmission 305).

[0102] In some examples, the third uplink transmission 310 may overlap with symbol 1 or symbol 3, or both. In some cases, the UE can determine the overlap, and then, based on the determined overlap, the UE can determine the priority of the content of the overlapping symbol (e.g., symbol 1 or symbol 3, or both) relative to the priority level of the third uplink transmission 310. In some cases, the UE can use a power control prioritization hierarchy to determine that the priority of the overlapping symbol is greater than the priority of the third uplink transmission 310. Therefore, symbol 1 or symbol 3, or both, of the multiplexed transmission 305 can be prioritized over the third uplink transmission 310 for transmit power (e.g., more transmit power can be allocated to symbol 1 or symbol 3, or both, on a per-symbol basis according to the corresponding priority, compared to the third uplink transmission 310).

[0103] Figure 4 A block diagram 400 of a device 405 supporting power control for uplink transmission multiplexing, according to an example described herein, is shown. Device 405 may be an example of various aspects of UE 115 as described herein. Device 405 may include a receiver 410, a transmitter 415, and a communications manager 420. Device 405 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0104] Receiver 410 may provide a unit for receiving information such as packets, user data, control information associated with various information channels (e.g., control channels, data channels, and information channels related to power control for uplink transmission multiplexing), or combinations thereof. Information may be transmitted to other components of device 405. Receiver 410 may utilize a single antenna or a collection of multiple antennas.

[0105] Transmitter 415 may provide a unit for transmitting signals generated by other components of device 405. For example, transmitter 415 may transmit information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to power control for uplink transmission multiplexing). In some examples, transmitter 415 may be co-located with receiver 410 in a transceiver module. Transmitter 415 may utilize a single antenna or a collection of multiple antennas.

[0106] Communication manager 420, receiver 410, transmitter 415, or various combinations thereof, or various components thereof, may be examples of units for performing various aspects of power control for uplink transmission multiplexing as described herein. For example, communication manager 420, receiver 410, transmitter 415, or various combinations thereof, or components thereof, may support methods for performing one or more of the functions described herein.

[0107] In some examples, the communication manager 420, receiver 410, transmitter 415, or various combinations thereof, or components thereof, may be implemented in hardware (e.g., in a communication management circuit). The hardware may include a processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, configured to or otherwise supporting units for performing the functions described herein. In some examples, the processor and memory coupled to the processor may be configured to perform one or more of the functions described herein (e.g., executing instructions stored in memory via the processor).

[0108] Alternatively or additionally, in some examples, the communication manager 420, receiver 410, transmitter 415, or various combinations thereof or components thereof may be implemented in code executed by a processor (e.g., as communication management software). If implemented in code executed by a processor, the functionality of the communication manager 420, receiver 410, transmitter 415, or various combinations thereof or components thereof may be performed by a general-purpose processor, DSP, central processing unit (CPU), ASIC, FPGA, or any combination of these or other programmable logic devices (e.g., units configured or otherwise supported for performing the functions described in this disclosure).

[0109] In some examples, the communication manager 420 may be configured to use or otherwise cooperate with the receiver 410, transmitter 415, or both to perform various operations (e.g., receiving, monitoring, transmitting). For example, the communication manager 420 may receive information from the receiver 410, send information to the transmitter 415, or be integrated with the receiver 410, transmitter 415, or both to receive information, send information, or perform various other operations described herein.

[0110] According to the examples disclosed herein, the communication manager 420 can support power control prioritization for wireless communications performed by the UE. For example, the communication manager 420 can be configured or otherwise support elements for assigning a first priority level to a multiplexed transmission on a first component carrier, the multiplexed transmission including a first uplink transmission multiplexed with a second uplink transmission, wherein the first priority level assigned to the multiplexed transmission is based on the priority of the content (e.g., the highest priority content) of the first and second uplink transmissions. The communication manager 420 can be configured or otherwise support elements for assigning a second priority level to a third uplink transmission on a second component carrier based on the content of a third uplink transmission, wherein the third uplink transmission overlaps temporally with the multiplexed transmission. The communication manager 420 can be configured or otherwise support elements for performing a multiplexed transmission on a first component carrier with a first transmit power and a third uplink transmission on a second component carrier with a second transmit power, wherein the first transmit power and the second transmit power are based on a first priority level and a second priority level, respectively.

[0111] By including or configuring the communication manager 420 according to the examples described herein, device 405 (e.g., controlling receiver 410, transmitter 415, communication manager 420 or a combination thereof or a processor otherwise coupled thereto) can support techniques for improving the user experience of one or more devices with longer battery life, improved quality of service, and increased data throughput by prioritizing power control of wireless communications, including multiplexed transmissions, to reduce processing, reduce power usage, and improve the utilization efficiency of communication resources.

[0112] Figure 5 A block diagram 500 of a device 505 supporting power control for uplink transmission multiplexing, according to an example described herein, is shown. Device 505 may be an example of aspects of device 405 or UE 115 as described herein. Device 505 may include a receiver 510, a transmitter 515, and a communication manager 520. Device 505 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0113] Receiver 510 may provide a unit for receiving information such as packets, user data, control information associated with various information channels (e.g., control channels, data channels, and information channels related to power control for uplink transmission multiplexing), or combinations thereof.
