[0002] The following relates to wireless communications including power control enhancements for uplink transmit multiplexing. [Background technology]

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasts, and the like. These systems may be capable of supporting 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), LTE-Advanced (LTE-A), or LTE-A Pro systems, and fifth-generation (5G) systems, sometimes referred to as New Radio (NR) systems. These systems may utilize 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 Spread 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 simultaneously supporting communication for multiple communication devices, sometimes referred to as user equipment (UE).

[0004] Some wireless systems support multiplexing of uplink transmissions. Summary of the Invention [Problem to be solved by the invention]

[0005] In some cases, it may be desirable to improve the effectiveness of multiplexing uplink transmissions. [Means for solving the problem]

[0006] The described techniques relate to improved methods, systems, devices, and apparatuses that support power control prioritization of wireless communications. Generally, the described techniques provide a user equipment (UE) that determines power control prioritization of wireless communications. In some cases, the UE may perform a multiplexed transmission on a first uplink carrier. The multiplexed transmission may include a first uplink transmission multiplexed with a second uplink transmission. The first uplink transmission and the second uplink transmission may have different priorities. The UE may assign a first priority level to the multiplexed transmission based on a priority content (e.g., a highest priority content) of the first uplink transmission and the second uplink transmission. Thus, the priority content determines the overall priority of the multiplexed transmission, whether it is the content of the first uplink transmission or the second uplink transmission.

[0007] In some cases, the UE may 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 may overlap in time with the multiplexing transmission. In some cases, the UE may perform the multiplexing transmission on the first component carrier at a first transmit power and the third uplink transmission on the second component carrier at a second transmit power. In some cases, the UE may determine the first transmit power based on the first priority level and may determine the second transmit power based on the second priority level. Otherwise, if the combined transmit power of the first and second uplink carriers exceeds a defined power cap, the calculated transmit powers for the first and second uplink carriers may be scaled back based on the respective priority levels of the uplink multiplexing transmission and the third uplink transmission, respectively. For example, if the first priority level exceeds the second priority level, the second transmit power may be scaled back by an amount greater than the first transmit power, or vice versa.

[0008] A method for power control prioritization of wireless communications 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, the first priority level assigned to the multiplexed transmission being based on a priority of content of the first uplink transmission and the second uplink transmission, assigning a second priority level to a third uplink transmission on the second component carrier based on content of the third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission, and conducting the multiplexed transmission on the first component carrier at a first transmit power and the third uplink transmission on the second component carrier at a second transmit power, the first transmit power and the second transmit power being based on the first priority level and the second priority level, respectively.

[0009] An apparatus is described for power control prioritization of wireless communications by a UE. 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, the first priority level assigned to the multiplexed transmission being based on a priority of content of the first uplink transmission and the second uplink transmission; assign a second priority level to a third uplink transmission on the second component carrier based on content of the third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission; and conduct the multiplexed transmission on the first component carrier at a first transmit power and the third uplink transmission on the second component carrier at a second transmit power, the first transmit power and the second transmit power being based on the first priority level and the second priority level, respectively.

[0010] Another apparatus is described for power control prioritization of wireless communications by a UE. The apparatus may include means 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, the first priority level assigned to the multiplexed transmission based on a priority of content of the first uplink transmission and the second uplink transmission, means for assigning a second priority level to a third uplink transmission on the second component carrier based on content of the third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission, and means for conducting the multiplexed transmission on the first component carrier at a first transmit power and the third uplink transmission on the second component carrier at a second transmit power, the first transmit power and the second transmit power based on the first priority level and the second priority level, respectively.

[0011] A non-transitory computer-readable medium storing code for power control prioritization of wireless communications by a UE is described, 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, the first priority level assigned to the multiplexed transmission based on a priority of content of the first uplink transmission and the second uplink transmission; assign a second priority level to a third uplink transmission on the second component carrier based on content of the third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission; and implement the multiplexed transmission on the first component carrier at a first transmit power and the third uplink transmission on the second component carrier at a second transmit power, the first transmit power and the second transmit power based on the first priority level and the second priority level, respectively.

[0012] In some examples of the methods, apparatus, and non-transitory computer-readable media described herein, assigning a first priority level to the multiplexed transmission may include operations, features, means, or instructions for assigning a first priority level to a first set of symbols of the multiplexed transmission, where the first set of symbols is 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, where the second set of symbols is associated with one of the first uplink transmission or the second uplink transmission.

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

[0014] In some examples of the methods, apparatus, 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.

[0015] In some examples of the methods, apparatus, and non-transitory computer-readable media described herein, according to a priority hierarchy, content associated with a random access channel on a primary cell may have a first priority (e.g., the highest priority), content associated with a sounding reference signal transmission may have a second priority (e.g., the lowest priority), the first priority having a higher priority than the second priority and a higher priority than the priority of an uplink control transmission or a priority of an uplink data transmission, or both, and the second priority having a lower priority than the priority of an uplink control transmission or a priority of an uplink data transmission, or both.

[0016] In some examples of the methods, apparatus, and non-transitory computer-readable media described herein, in accordance with a priority hierarchy, content associated with a physical uplink channel that includes one or more of a high priority hybrid automatic repeat request acknowledgment feedback, or a high priority scheduling request, or a high priority link recovery request, may have a higher priority than content associated with a physical uplink channel that includes high priority channel status information.

[0017] In some examples of the methods, apparatus, and non-transitory computer-readable media described herein, according to a priority hierarchy, content associated with a physical uplink channel that includes high priority channel condition information may have a higher priority than content associated with a high priority physical uplink shared channel that does not have high priority hybrid automatic repeat request acknowledgment feedback or high priority channel condition information.

[0018] In some examples of the methods, apparatus, and non-transitory computer-readable media described herein, according to a priority hierarchy, content associated with a high priority physical uplink shared channel that lacks high priority uplink control information may have a higher priority than content associated with a low priority physical uplink channel that includes one or more of low priority hybrid automatic repeat request acknowledgment feedback, or low priority scheduling requests, or low priority link recovery requests, or any combination thereof.

[0019] In some examples of the methods, apparatus, and non-transitory computer-readable media described herein, in accordance with a priority hierarchy, content associated with a low priority physical uplink channel, including one or more of low priority hybrid automatic repeat request acknowledgment feedback, or low priority scheduling requests, or low priority link recovery requests, may have a higher priority than content associated with a low priority physical uplink channel, including low priority channel state information.

[0020] In some examples of the methods, apparatus, and non-transitory computer-readable media described herein, according to a priority hierarchy, content associated with a low priority physical uplink channel, which includes low priority channel state information, may have a higher priority than content associated with a low priority physical uplink shared channel, which lacks uplink control information.

[Figure 9] 1 is a flowchart illustrating a method for supporting enhanced power control according to examples described herein. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] The techniques include power control prioritization of wireless communications. Some systems may include two priority levels for uplink transmissions (e.g., low priority (LP or priority 0) and high priority (HP) or priority 1) for transmitting traffic 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 with HP content or HP payload) and LP uplink transmissions (e.g., uplink transmissions with LP content or LP payload). An example of HP content may include ultra-reliable low latency communications (URLLC) traffic. An example of LP content may include enhanced mobile broadband (eMBB) traffic.

[0023] In some examples, when an LP transmission collides with an HP transmission (e.g., the time resources of the LP transmission at least partially overlap with the time resources of the HP transmission), the LP transmission may be dropped. However, dropping the transmission may result in retransmissions and a poor user experience. Thus, some systems may multiplex uplink transmissions with different priorities into one multiplexed transmission (e.g., HP uplink transmission and LP uplink transmission multiplexed into a single multiplexed transmission). In some cases, the two uplink transmissions may be multiplexed using puncturing or rate matching. In some cases, the coding rate may be changed to allow for the transmission of both uplink transmissions.

[0024] In some examples, a UE may multiplex both HP and LP content into a multiplexed transmission. In some examples, a UE may multiplex both HP uplink control information (UCI) and LP UCI into a physical uplink control channel, or multiplex HP UCI on a LP physical uplink shared channel, or multiplex LP UCI on a HP physical uplink shared channel. However, some systems do not have techniques for determining priority between a multiplexed transmission with mixed priority and other uplink transmissions.

[0025] The techniques allow devices to prioritize between multiplexed transmissions and other uplink transmissions. In particular, the techniques provide power control enhancements for HP and LP uplink transmission multiplexes.

[0026] In some examples, the UE may be configured to transmit multiple physical uplink channels on a corresponding uplink carrier. In some cases, the UE may be configured to transmit one physical uplink control channel and one physical uplink shared channel, or two physical uplink control channels in a corresponding physical uplink control channel group.

[0027] In some examples, when two or more uplink transmissions are scheduled at the same time (e.g., symbols of two or more uplink transmissions at least partially overlap in time), the UE may perform power prioritization to determine how much power to allocate to a first uplink transmission of the two or more uplink transmissions and how much power to allocate to a second uplink transmission of the two or more uplink transmissions. Based on the present techniques for power control prioritization, the priority of an uplink transmission may be determined by the priority of content contained within the uplink transmission. The power control prioritization may be based on a power control prioritization hierarchy indicating a priority from highest to lowest priority based on content characteristics (e.g., content type, etc.).

[0028] Aspects of the subject matter described herein may be implemented to achieve one or more advantages. The described techniques may support improved transmit power control of multiplexed transmissions based on determined priorities of uplink transmissions. Furthermore, the described techniques may avoid dropped transmissions, multiple retransmissions, and failed transmissions, reduce system latency, improve reliability of decoding high priority uplink transmissions at base stations, and improve user experience.

[0029] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated by and described with reference to a wireless communication system environment relating to power control for uplink transmission multiplexing. Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow charts relating to power control for uplink transmission multiplexing.

[0030] 1 illustrates an example of a wireless communication system 100 supporting power control for uplink transmit multiplexing according to examples described herein. 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, a LTE-Advanced (LTE-A) network, a LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0031] The base stations 105 may be distributed throughout a geographic area to form a wireless communication system 100 and may be devices of different forms or with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. The base stations 105 may provide a coverage area 110 over which the UEs 115 and the base stations 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 may support communication of signals via one or more radio access technologies.

[0032] The UEs 115 may be distributed throughout the coverage area 110 of the wireless communication system 100, and at least one UE 115 may be fixed or mobile or both at different times. The UEs 115 may be devices of different forms or with different capabilities. Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment) as shown in FIG. 1.

[0033] The base stations 105 may communicate with the core network 130, or with each other, or both. For example, the base stations 105 may interface with the core network 130 through one or more backhaul links 120 (e.g., via an S1, N2, N3, or other interface). The base stations 105 may communicate with each other over the backhaul links 120 (e.g., via an X2, Xn, or other interface), either directly (e.g., directly between the base stations 105), or indirectly (e.g., via the core network 130), or both. In some examples, the backhaul links 120 may be or include one or more wireless links.

[0034] One or more of the base stations 105 described herein may include or be referred to as a base transceiver station, radio base station, access point, radio transceiver, Node B, eNode B (eNB), Next Generation Node B or Giga Node B (any of which may be referred to as a gNB), Home Node B, Home eNode B, or other suitable terminology by those skilled in the art.

[0035] The UE 115 may include or be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, and a "device" may also be referred to as a unit, a station, a terminal, or a client, among other examples. The UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, the UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, among other examples, which may be implemented in various articles, such as an appliance, or a vehicle, a meter, among other examples.

[0036] The UEs 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may act as relays, as shown in FIG. 1, as well as base stations 105 and network equipment, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples.

[0037] The UE 115 and the base station 105 may wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier used for the communication link 125 may include a portion (e.g., a bandwidth portion (BWP)) of a radio frequency spectrum band operated 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 collection signaling (e.g., synchronization signals, system information), control signaling to coordinate operation for the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0038] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have collection or control signaling to coordinate operation with respect to other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be arranged according to a channel raster for discovery by the UE 115. A carrier may be operated in a standalone mode where initial collection and connection may be made by the UE 115 over the carrier, or the carrier may be operated in a non-standalone mode where a connection is anchored using a different carrier (e.g., of the same or different radio access technology).

[0039] The communication links 125 shown in the wireless communication system 100 may include uplink transmissions from the UE 115 to the base station 105 or downlink transmissions from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in FDD mode) or may be configured to carry downlink and uplink communications (e.g., in TDD mode).

[0040] A carrier may be associated with a particular 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 several predefined bandwidths for a particular radio access technology carrier (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). The devices of the wireless communication system 100 (e.g., the base station 105, the UE 115, or both) may have a hardware configuration that supports communication on a particular carrier bandwidth or may be configurable to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or a UE 115 that supports simultaneous communication via a carrier associated with multiple carrier bandwidths. In some examples, the served UE 115 may be configured to operate on a portion (e.g., a sub-band, BWP), or all, of the carrier bandwidth.

[0041] A signal waveform transmitted on a carrier may be composed of multiple subcarriers (e.g., using a multicarrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system utilizing MCM techniques, a resource element may include one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely proportional. The number of bits carried by a resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Thus, the more resource elements and the higher the order of the modulation scheme that the UE 115 receives, the higher the data rate of the UE 115 may be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), where the use of multiple spatial layers may further increase the data rate or data integrity for communications with the UE 115.

[0042] One or more numerologies for a carrier may be supported, where the numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communication for the UE 115 may be limited to one or more active BWPs.

[0043] The time interval for the base station 105 or the UE 115 may be, for example, T s =1 / (Δf max N f ) seconds, where Δf max may represent the maximum supported subcarrier spacing, and N fmay represent the maximum supported discrete Fourier transform (DFT) size. The communication resource time intervals may be organized according to radio frames having a specified duration (e.g., 10 milliseconds (ms)). The radio frames may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0044] A frame may include multiple consecutively numbered subframes or slots, and the subframes or slots may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and the subframes may be further divided into several slots. Alternatively, a frame may include a variable number of slots, and the number of slots may depend on the subcarrier spacing. A slot may include several symbol periods (e.g., depending on the length of a cyclic prefix prepended to a symbol period). In some wireless communications systems 100, a slot may be further divided into multiple minislots that include one or more symbols. Excluding the cyclic prefix, a symbol period may be one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the frequency band of operation.

[0045] A subframe, slot, minislot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0046] The physical channels may be multiplexed on the carriers according to various techniques. The physical control channels and the physical data channels may be multiplexed on the downlink carriers, for example, using one or more of a time division multiplexing (TDM), a frequency division multiplexing (FDM), or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (core set)) for the physical control channel may be defined by a number of symbol periods and may extend across the system bandwidth of the carrier or a subset of the system bandwidth. One or more control regions (e.g., core sets) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may monitor or search the control region for control information according to one or more search space sets, which may include one or more control channel candidates at one or more aggregation levels arranged in a cascaded manner. The aggregation level for the control channel candidates may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for sending control information to multiple UEs 115 and a UE-specific search space set for sending control information to a particular UE 115.

[0047] In some examples, the base stations 105 may be mobile and thus provide communication coverage to moving geographic coverage areas 110. In some examples, the different geographic coverage areas 110 associated with different technologies may overlap, but 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. The wireless communication system 100 may include a heterogeneous network, for example, where different types of base stations 105 provide coverage to various geographic coverage areas 110 using the same or different radio access technologies.

[0048] The wireless communication system 100 may be configured to support ultra-reliable or low latency communications, or various combinations thereof. For example, the wireless communication system 100 may be configured to support URLLC or mission-critical communications. The UE 115 may be designed to support ultra-reliable, low latency, or critical functionality (e.g., mission-critical functionality). Ultra-reliable communications may include private or group communications 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 functionality may include service prioritization, and the 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 may be used interchangeably herein.

[0049] In some examples, the UE 115 may also be able to communicate directly with other UEs 115 via device-to-device (D2D) communication links 135 (e.g., using a peer-to-peer (P2P) protocol or a D2D protocol). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or may not be able to receive transmissions from the base station 105 in some cases. In some examples, a group of UEs 115 communicating via D2D communication may use a one-to-many (1:M) system in which at least one UE 115 transmits to one or more other (e.g., all other) UEs 115 in the group. In some examples, the base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication occurs between UEs 115 without the involvement of the base station 105.

[0050] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) that routes packets or interconnects to external networks. The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the base stations 105 associated with the core network 130. User IP packets may be forwarded through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to one or more network operators' IP services 150. The IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0051] Some of the network devices, such as the base station 105, may include subcomponents, such as an access network entity 140, which may be an example of an access node controller (ANC). The access network entity 140 (e.g., each access network entity 140) may communicate with the UE 115 through one or more other access network transmitting entities 145, which may be referred to as a radio head, a smart radio head, or a transmit / receive point (TRP). The access network transmitting entity 145 may include one or more antenna panels. In some configurations, various functions of the access network entity 140 (e.g., each access network entity 140) or the base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or integrated into a single network device (e.g., the base station 105).

[0052] The wireless communication system 100 may operate using one or more frequency bands (e.g., within the range of 300 megahertz (MHz) to 300 gigahertz (GHz)). The 300 MHz to 3 GHz region is commonly referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range in length from approximately 1 decimeter to 1 meter. Although UHF waves may be blocked or redirected by buildings and environmental features, the waves may penetrate structures sufficiently for a macrocell to serve UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmissions using lower frequencies and longer waves in the short wave (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0053] The wireless communication system 100 may use both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may utilize Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band, such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in an unlicensed radio frequency spectrum band, devices such as the base station 105 and the UE 115 may utilize carrier sensing for collision detection and avoidance. In some examples, operation in an unlicensed band may be based on a carrier aggregation configuration in conjunction with component carriers operating in a licensed band (e.g., LAA). Operation in an unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0054] The base station 105 or UE 115 may be equipped with multiple antennas that may be used to utilize techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located in one or more antenna arrays or antenna panels that may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located in an antenna assembly such as an antenna tower. In some examples, antennas or antenna arrays associated with the base station 105 may be located in various geographic locations. The base station 105 may have an antenna array with several rows and columns of antenna ports that the base station 105 may use to support beamforming of communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panels may support radio frequency beamforming for signals transmitted through the antenna ports.

[0055] Beamforming, sometimes referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used in a transmitting or receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals communicated through antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array are subject to constructive interference and other signals are subject to destructive interference. Adjustment of signals communicated through antenna elements may include the transmitting or receiving device applying an amplitude offset, a phase offset, or both to signals conveyed through an antenna element associated with the device. The adjustment associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., relative to the transmitting or receiving device's antenna array or to some other orientation).

[0056] The UE 115 and the base station 105 may support retransmission of data to increase the likelihood of successful reception of the data. Hybrid Automatic Repeat Request (HARQ) feedback is one technique for increasing the likelihood that data will be correctly received on the communication link 125. HARQ may include a combination of error detection (e.g., using a Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ may improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device may support same-slot HARQ feedback, in which the device may provide HARQ feedback in a particular slot for data received in a previous symbol in that slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0057] In some examples, a UE (e.g., UE 115 of FIG. 1) may perform power control prioritization of wireless communications. In some cases, the UE performing power control prioritization may include the UE assigning a first priority level 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 level assigned to the multiplexed transmission is based on a priority of the first uplink transmission and the content (e.g., the highest priority content) of the second uplink transmission. In some cases, the UE may assign a second priority level to a third uplink transmission on the second component carrier based on a content of the third uplink transmission. In some cases, the third uplink transmission overlaps at least partially in time with the multiplexed transmission. In some cases, the UE may perform the multiplexed transmission on the first component carrier at a first transmit power and the third uplink transmission on the second component carrier at a second transmit power. In some cases, the first transmit power and the second transmit power are based on the first priority level and the second priority level, respectively. In some cases, the UE may transmit a multiplexed transmission or a third uplink transmission, or both, to a base station (e.g., to base station 105 of FIG. 1).

[0058] FIG. 2 illustrates an example wireless communication subsystem 200 that supports power control for uplink transmit multiplexing in accordance with examples described herein.

[0059] As shown, the wireless communications subsystem 200 may include a UE 115-a and a base station 105-a, which may be examples of a UE 115 or a base station 105, as described herein with reference to FIG. 1. The wireless communications subsystem 200 may also include an uplink 205 and an uplink 210. In some cases, the wireless communications subsystem 200 may also include a downlink. The base station 105-a may use the downlink to communicate control and / or data information to the UE 115-a. Also, the UE 115-a may use the uplink 205 or the uplink 210, or both, to communicate control and / or data information to the base station 105-a. In some cases, the downlink may use different time and / or frequency resources than the uplink 205 or the uplink 210, or both.

[0060] In some examples, the UE 115-a may implement power control prioritization of wireless communications between the UE 115-a and the base station 105-a. In some cases, the UE 115-a may determine a priority of content carried on each uplink transmission and then determine a transmit power for each uplink transmission based on the respective determined priority.

[0061] In some examples, the UE 115-a performing power control prioritization may include the UE 115-a assigning a first priority level to the multiplexed transmission 215 on the first component carrier of the 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, which has the highest priority content. In some cases, the content of the first uplink transmission may have the highest priority content. Thus, 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. Thus, the content of the second uplink transmission determines the priority level assigned to the multiplexed transmission 215.

[0062] In some cases, the UE 115-a may determine that the third uplink transmission 220 at least partially overlaps in time with the multiplexed transmission 215. In some cases, based on the determined overlap, the UE 115-a may determine and assign a first priority level for the multiplexed transmission 215 and may determine and assign a second priority level for the third uplink transmission 220. In some cases, the UE 115-a may assign a second priority level to the third uplink transmission 220 on the second component carrier of the uplink 210 based on the content of the third uplink transmission 220 (e.g., based on the content of the third uplink transmission 220 compared to the content of the multiplexed transmission 215).

[0063] In some cases, the UE 115-a may perform the multiplexed transmission 215 on the first component carrier at a first transmit power and the third uplink transmission 220 on the second component carrier at a second transmit power. In some cases, the first transmit power may be based on a first priority level and the second transmit power may be based on a second priority level. In some examples, the first priority level and the second priority level may be based on a power control prioritization hierarchy. As shown, the UE 115-a may transmit the multiplexed transmission 215 to the base station 105-a, or the third uplink transmission 220 to the base station 105-a, or both to the base station 105-a.

[0064] The techniques improve power usage and efficiency of one or more devices (e.g., a battery-powered device, such as UE 115 of FIG. 1 or FIG. 2) by prioritizing power control of wireless communications including multiplexed transmissions, and thus improve the user experience of the one or more devices with longer battery life, improved quality of service, and improved data throughput.

[0065] FIG. 3 illustrates an example environment 300 that supports power control for uplink transmit multiplexing in accordance with examples described herein.

[0066] In the illustrated example, the environment 300 may include a multiplexed transmission 305 including at least a first uplink transmission and a second uplink transmission, where at least the first uplink transmission is multiplexed with the second uplink transmission. As shown, the environment 300 may also include a third uplink transmission 310.

[0067] In the illustrated example, the multiplexed transmission 305 may include several symbols (e.g., in the example given, 11 symbols) that may include various contents or payloads. In some cases, the symbols may include OFDM symbols. As shown, the multiplexed transmission 305 may include a high priority HARQ acknowledgement (HARQ-ACK) feedback 315. As shown, the HARQ-ACK feedback 315 may occupy (e.g., piggybacked 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 illustrated example, 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) 325-a through 325-i) occupying symbol 0, a portion of symbol 3, symbols 4 through 7, and symbols 9 through 11. In some cases, the multiplexed transmission 305 may be designated as a low priority uplink transmission. In some cases, the multiplexed transmission 305 may be designated as a low priority uplink transmission based on the content of the multiplexed transmission 305 (e.g., based on the low priority physical uplink channel 325).

[0068] In the illustrated example, the third uplink transmission 310 may include a physical uplink channel (e.g., a PUSCH or a PUCCH) that may include various content or payloads. In some cases, the third uplink transmission 310 may be designated a high priority uplink channel. In some cases, the third uplink transmission 310 may be designated a high priority uplink channel based on the content of the third uplink transmission 310.

[0069] In some examples, the content of the uplink transmissions may determine the priority of each uplink transmission according to a power control prioritization hierarchy. In some cases, the power control prioritization hierarchy may indicate that content associated with a random access channel on the primary cell has a first priority (e.g., the highest overall priority) and content associated with a sounding reference signal transmission has a second priority (e.g., the lowest overall priority).

[0070] For purposes of power control prioritization, the priority of an uplink transmission may be determined by the highest priority of the content / payload contained in the uplink transmission among the following: High priority HARQ-ACK, Scheduling Request (SR), Link Recovery Request (LRR), ·High priority CSI, High priority uplink UL-SCH (e.g. uplink data), ·Low priority HARQ-ACK, SR, LRR, Low priority Channel Status Information (CSI), · Low priority UL-SCH (e.g. uplink data).

[0071] For example, a PUCCH with both low priority and high priority HARQ-ACK may be determined to have the same priority as a high priority PUCCH with HARQ-ACK. In some cases, a low priority PUSCH carrying a high priority HARQ-ACK may 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 may be determined to have the same priority as a high priority PUSCH without a HARQ-ACK.

[0072] In some examples, a priority hierarchy for NR uplink transmissions, from highest priority to lowest priority, may be configured as follows: 1. A physical random access channel on the primary cell; 2. PUCCH / PUSCH containing high priority HARQ-ACK and / or high priority SR and / or high priority LRR (and may contain other content, e.g., low priority HARQ-ACK, low priority CSI, etc.); 3. PUCCH / PUSCH with high priority CSI; 4. High-priority PUSCH with neither high-priority HARQ-ACK nor high-priority CSI; 5. A low priority PUCCH / PUSCH including a low priority HARQ-ACK and / or a low priority SR and / or a low priority LRR; 6. Low priority PUCCH / PUSCH with low priority CSI; 7. Low priority PUSCH without HARQ-ACK or CSI. 8. Sounding Reference Signal (SRS) transmission.

[0073] In some examples, the power control prioritization hierarchy may indicate that content associated with a physical uplink channel that includes one or more of a HARQ-ACK, or a high priority SR, or a high priority LRR (e.g., the content of the multiplexed transmission 305 or the content of the third uplink transmission 310) has a higher priority than content associated with a physical uplink channel that includes a high priority CSI.

[0074] In some examples, the power control prioritization hierarchy may indicate that content including high priority CSI has a higher priority than content associated with a high priority physical uplink shared channel without high priority HARQ-ACK feedback and high priority CSI. In some examples, the power control prioritization hierarchy may indicate that content associated with a high priority physical uplink shared channel without high priority HARQ-ACK feedback and high priority CSI has a higher priority than content associated with a low priority physical uplink channel including one or more of low priority HARQ-ACK feedback, or low priority SR, or low priority LRR, or any combination thereof.

[0075] In some examples, the power control prioritization hierarchy may indicate that content associated with a low priority physical uplink channel, including 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, including low priority CSI. In some examples, the power control prioritization hierarchy may indicate that content associated with a low priority physical uplink channel, including low priority CSI, has a higher priority than content associated with a low priority physical uplink shared channel, without HARQ-ACK feedback and channel state information.

[0076] In some examples, a physical uplink channel with both low priority and high priority HARQ-ACK may be determined to have the same priority as a high priority physical uplink channel with HARQ-ACK according to a power control prioritization hierarchy. A low priority physical uplink channel carrying a high priority HARQ-ACK feedback (e.g., low priority physical uplink channel 325 of multiplexed transmission 305) may be determined to have the same priority as an uplink transmission with a high priority HARQ-ACK feedback according to a power control prioritization hierarchy. A high priority physical uplink channel carrying a low priority HARQ-ACK may be determined to have the same priority as a high priority physical uplink channel without a HARQ-ACK according to a power control prioritization hierarchy.

[0077] The techniques may include a UE (e.g., UE 115 of FIG. 1 or FIG. 2) applying a power control prioritization hierarchy on a per-transmission basis. In some cases, a first uplink carrier may be associated with the multiplexed transmission 305, and a second uplink carrier may be associated with the 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 ceiling, the transmit powers calculated for the first and second uplink carriers may be scaled back based on the respective priority levels of the multiplexed transmission 305 and the third uplink transmission 310, respectively. When the multiplexed transmission 305 is designated a low priority uplink transmission and the third uplink transmission 310 is designated a high priority uplink channel, or when the UE determines that the priority level of the third uplink transmission 310 exceeds the priority level of the multiplexed transmission 305, the UE may scale back the transmit power of the multiplexed transmission 305 by an amount greater than the transmit power of the third uplink transmission 310. In some cases, when the multiplex transmission 305 and the third uplink transmission 310 are scheduled with transmission powers P1 and P2, respectively, and the total power is greater than P_max (e.g., P1+P2>P_max), the UE may allocate power to the higher priority transmission first until the allocated power of the higher priority transmission reaches the corresponding scheduled power (e.g., P1 for the multiplex transmission 305 or P2 for the third uplink transmission 310). The UE may then allocate the remaining power (e.g., of the total available power up to P_max) to the lower priority transmission. In some cases, when the scheduled power of the high priority transmission exceeds P_max, the UE may allocate power (e.g., all of the power) to the high priority transmission and no power to the low priority channel (e.g., the low priority channel may be dropped).In some cases, when 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 UE determines that the priority level of the multiplexed transmission 305 exceeds the priority level of the third uplink transmission 310, the UE may scale back the transmission power of the third uplink transmission 310 by an amount greater than the transmission power of the multiplexed transmission 305.

[0078] The techniques may include a UE (e.g., the UE 115 of FIG. 1 or FIG. 2) applying a power control prioritization hierarchy on a symbol-by-symbol basis (e.g., on an OFDM symbol-by-symbol basis). Thus, the UE may apply a power control prioritization hierarchy to the symbol multiplexed transmission 305 on a symbol-by-symbol basis. For example, the UE may apply a first priority to symbol 1 of the multiplexed transmission 305 based on the content of symbol 1 (e.g., a high priority uplink transmission), apply a second priority, different from the first priority, to symbol 2 of the multiplexed transmission 305 based on the content of symbol 2 (e.g., a low priority uplink transmission), and so on. In some cases, the UE may determine the priority of the content carried on each symbol and determine the transmit power for each symbol based on the respective determined priorities. In some cases, the priority of the DMRS symbols 320 of the multiplexed transmission 305 may be equal to the priority of the highest priority content in the multiplexed transmission 305 (e.g., the priority of the DMRS 320 may be equal to the priority of the HARQ-ACK feedback 315).

[0079] In some examples, the priority may be determined on a symbol-by-symbol basis for a given uplink transmission. In some cases, a first set of one or more symbols of the multiplexed transmission 305 may have a first priority, and a second set of one or more symbols of the multiplexed transmission 305 may have a second priority different from the first priority, but the multiplexed transmission 305 has no priority as a whole. Similarly, a first set of one or more symbols of the third uplink transmission 310 may have a first priority, and a second set of one or more symbols of the third uplink transmission 310 may have a second priority different from the first priority, but the third uplink transmission 310 has no priority as a whole. Alternatively, in some cases, the priority may be determined by the traffic type of a given uplink transmission. In some cases, the multiplexed transmission 305 may be designated as an overall low priority physical uplink channel (e.g., because the multiplexed transmission 305 is associated with eMBB traffic), while the third uplink transmission 310 may be designated as an overall high priority physical uplink channel (e.g., because the third uplink transmission 310 is associated with URLLC traffic). In some cases, the UE may determine the priority of the uplink transmission. In some cases, the base station may determine the priority of the uplink transmission.

[0080] In the illustrated example, the multiplex transmission 305 may include high priority content. For example, symbol 1 and a portion of symbol 3 of the multiplex transmission 305 include HARQ-ACK feedback 315. Thus, at least symbol 1 and a portion of symbol 3 of the multiplex transmission 305 may be designated as high priority based on the content of symbol 1 and the portion of symbol 3 that carry the HARQ-ACK feedback 315. However, because symbols 1 through 3 of the multiplex transmission 305 do not overlap with the third uplink transmission 310, symbols 1 through 3 of the multiplex transmission 305 may be transmitted without determining or considering a power prioritization between the multiplex transmission 305 and the third uplink transmission 310.

[0081] In the illustrated example, the third uplink transmission 310 at least partially overlaps in time with the multiplex transmission 305. As illustrated, the third uplink transmission 310 overlaps with symbols 4 through 11 of the multiplex transmission 305. In some cases, an associated UE may determine that the multiplex transmission 305 and the third uplink transmission 310 overlap at symbols 4 through 11 of the multiplex transmission 305. Based on the determined overlap, the UE may determine that the third uplink transmission 310 is designated as a high priority physical uplink channel. Also, based on the determined overlap, the UE may determine a priority of the content of each overlapped symbol (e.g., symbols 4 through 11 of the multiplex transmission 305). In some cases, the UE may use a power control prioritization hierarchy to determine the priority of each overlapped symbol. In some cases, the UE may assign a priority level to each of the overlapped symbols.

[0082] In the illustrated example, the UE may determine that the priority level of the content of each of symbols 4 through 11 has a lower priority than the content of the third uplink transmission 310. Thus, the UE may prioritize the transmit power of the third uplink transmission 310 over the transmit power of symbols 4 through 11 of the multiplexed transmission 305. Thus, the third uplink transmission 310 may be prioritized in transmit power over symbols 4 through 11 of the multiplexed transmission 305 (e.g., more transmit power may be allocated to the third uplink transmission 310 than to symbols 4 through 11 of the multiplexed transmission 305 according to their respective priorities on a symbol-by-symbol basis).

[0083] In some examples, the third uplink transmission 310 may overlap with symbol 1 or symbol 3, or both. In some cases, the UE may determine the overlap, and then based on the determined overlap, the UE may determine a priority of the content of the overlapped symbols (e.g., symbol 1 or symbol 3, or both) with respect to the priority level of the third uplink transmission 310. In some cases, the UE may use a power control prioritization hierarchy to determine that the priority of the overlapped symbols is greater than the priority of the third uplink transmission 310. Thus, symbol 1 or symbol 3, or both of the multiplexed transmission 305 may be prioritized for transmit power over the third uplink transmission 310 (e.g., more transmit power may be allocated to symbol 1 or symbol 3, or both, than to the third uplink transmission 310 according to their respective priorities on a symbol-by-symbol basis).

[0084] 4 illustrates a block diagram 400 of a device 405 supporting power control for uplink transmit multiplexing, according to examples described herein. The device 405 may be an example of an aspect of a UE 115 as described herein. The device 405 may include a receiver 410, a transmitter 415, and a communications manager 420. The device 405 may also include a processor. Each of these components may communicate with one another (e.g., via one or more buses).

[0085] The receiver 410 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various traffic channels (e.g., control channels, data channels, traffic channels associated with power control for uplink transmission multiplexing). The information may be passed to other components of the device 405. The receiver 410 may use a single antenna or a set of multiple antennas.

[0086] The transmitter 415 may provide a means for transmitting signals generated by other components of the device 405. For example, the transmitter 415 may transmit information such as packets, user data, control information, or any combination thereof associated with various traffic channels (e.g., control channels, data channels, traffic channels associated with power control for uplink transmit multiplexing). In some examples, the transmitter 415 may be co-located with the receiver 410 in a transceiver module. The transmitter 415 may use a single antenna or a set of multiple antennas.

[0087] The communications manager 420, the receiver 410, the transmitter 415, or various combinations or components thereof may be examples of means for implementing various aspects of power control for uplink transmit multiplexing as described herein. For example, the communications manager 420, the receiver 410, the transmitter 415, or various combinations or components thereof may support a method for implementing one or more of the functions described herein.

[0088] In some examples, the communications manager 420, the receiver 410, the transmitter 415, or various combinations or components thereof may be implemented in hardware (e.g., in communications management circuitry). The hardware may include a processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof configured as or otherwise supporting a means for performing functions described in this disclosure. In some examples, the processor, and a memory coupled to the processor, may be configured to perform one or more of the functions described herein (e.g., by executing, by the processor, instructions stored in the memory).

[0089] Additionally or alternatively, in some examples, the communications manager 420, the receiver 410, the transmitter 415, or various combinations or components thereof may be implemented in code executed by a processor (e.g., as communications management software). If implemented in code executed by a processor, the functions of the communications manager 420, the receiver 410, the transmitter 415, or various combinations or components thereof may be performed by a general purpose processor, a DSP, a central processing unit (CPU), an ASIC, an FPGA, or any combination of these or other programmable logic devices (e.g., configured as or otherwise supporting a means for performing the functions described in this disclosure).

[0090] In some examples, the communications manager 420 may be configured to perform various operations (e.g., receiving, monitoring, transmitting) using or otherwise cooperating with the receiver 410, the transmitter 415, or both. For example, the communications manager 420 may receive information from the receiver 410, send information to the transmitter 415, or be integrated in combination with the receiver 410, the transmitter 415, or both to receive information, transmit information, or perform various other operations described herein.

[0091] The communications manager 420 may support power control prioritization of wireless communications by a UE according to examples disclosed herein. For example, the communications manager 420 may be configured as or otherwise support a means 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, the first priority level assigned to the multiplexed transmission based on a priority of the first uplink transmission and the content (e.g., highest priority content) of the second uplink transmission. The communications manager 420 may be configured as or otherwise support a means for assigning a second priority level to a third uplink transmission on a second component carrier based on a content of the third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission. The communications manager 420 may be configured with or otherwise support a means for implementing a multiplexed transmission on a first component carrier at a first transmit power and a third uplink transmission on a second component carrier at a second transmit power, the first transmit power and the second transmit power being based on a first priority level and a second priority level, respectively.

[0092] By including or configuring the communications manager 420 in accordance with the examples described herein, the device 405 (e.g., a processor controlling or otherwise coupled to the receiver 410, the transmitter 415, the communications manager 420, or a combination thereof) can support techniques for reducing processing, reducing power usage, and improving efficiency of use of communications resources by prioritizing power control of wireless communications including multiplexed transmissions, thus improving the user experience of one or more devices with longer battery life, improved quality of service, and improved data throughput.

[0093] 5 illustrates a block diagram 500 of a device 505 supporting power control for uplink transmit multiplexing, according to examples described herein. The device 505 may be an example of an aspect of a device 405 or a UE 115 as described herein. The device 505 may include a receiver 510, a transmitter 515, and a communications manager 520. The device 505 may also include a processor. Each of these components may communicate with one another (e.g., via one or more buses).

[0094] The receiver 510 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various traffic channels (e.g., control channels, data channels, traffic channels associated with power control for uplink transmission multiplexing). The information may be passed to other components of the device 505. The receiver 510 may use a single antenna or a set of multiple antennas.

[0095] The transmitter 515 may provide a means for transmitting signals generated by other components of the device 505. For example, the transmitter 515 may transmit information such as packets, user data, control information, or any combination thereof associated with various traffic channels (e.g., control channels, data channels, traffic channels associated with power control for uplink transmit multiplexing). In some examples, the transmitter 515 may be co-located with the receiver 510 in a transceiver module. The transmitter 515 may use a single antenna or a set of multiple antennas.

The overlap manager 530 may be configured as or otherwise support a means for assigning a second priority level to a third uplink transmission on a second component carrier based on a content of the third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission. The transmission manager 535 may be configured with or otherwise support a means for implementing a multiplexed transmission on a first component carrier at a first transmit power and a third uplink transmission on a second component carrier at a second transmit power, the first transmit power and the second transmit power being based on a first priority level and a second priority level, respectively.

[0098] 6 illustrates a block diagram 600 of a communications manager 620 supporting power control for uplink transmit multiplexing, according to examples described herein. Communications manager 620 may be an example of aspects of communications manager 420, communications manager 520, or both described herein. Communications manager 620, or various components thereof, may be examples of means for implementing various aspects of power control for uplink transmit multiplexing, described herein. For example, communications manager 620 may include a priority manager 625, a duplication manager 630, a transmission manager 635, or any combination thereof. Each of these components may communicate with one another directly or indirectly (e.g., via one or more buses).

[0099] The communications manager 620 may support power control prioritization of wireless communications by a UE according to examples disclosed herein. The communications manager 625 may be configured as or otherwise support a means 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, the first priority level assigned to the multiplexed transmission based on a priority of the first uplink transmission and the content (e.g., highest priority content) of the second uplink transmission. The overlap manager 630 may be configured as or otherwise support a means for assigning a second priority level to a third uplink transmission on a second component carrier based on a content of the third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission. The transmission manager 635 may be configured with or otherwise support a means for implementing a multiplexed transmission on a first component carrier at a first transmit power and a third uplink transmission on a second component carrier at a second transmit power, the first transmit power and the second transmit power being based on a first priority level and a second priority level, respectively.

[0100] In some examples, to support assigning a first priority level to the multiplexed transmission, the priority manager 625 may be configured or otherwise support a means for assigning a first priority level to a first set of symbols of the multiplexed transmission, the first set of symbols being associated with the first uplink transmission and the second uplink transmission. In some examples, to support assigning a first priority level to the multiplexed transmission, the overlap manager 630 may be configured or otherwise support a means for assigning a third priority level to a second set of symbols of the multiplexed transmission, the second set of symbols being associated with one of the first uplink transmission or the second uplink transmission.

[0102] In some examples, the first priority level or the second priority level, or both, are determined according to a priority hierarchy, and 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. In some examples, according to the priority hierarchy, the content associated with the random access channel on the primary cell has a first priority (e.g., the highest priority) and the content associated with the sounding reference signal transmission has a second priority (e.g., the lowest priority). In some examples, according to the priority hierarchy, the content associated with the physical uplink channel that includes one or more of a high priority hybrid automatic repeat request acknowledgment feedback, or a high priority scheduling request, or a high priority link recovery request has a higher priority than the content associated with the physical uplink channel that includes high priority channel condition information.

[0103] In some examples, according to a priority hierarchy, content associated with a physical uplink channel that includes high priority channel status information has a higher priority than content associated with a high priority physical uplink shared channel that is absent of high priority uplink control information. In some examples, according to a priority hierarchy, content associated with a high priority physical uplink shared channel that is absent of any one of high priority hybrid automatic repeat request acknowledgment feedback or high priority channel status information has a higher priority than content associated with a low priority physical uplink channel that includes one or more of low priority hybrid automatic repeat request acknowledgment feedback, or low priority scheduling request, or low priority link recovery request, or any combination thereof. In some examples, according to a priority hierarchy, content associated with a high priority physical uplink shared channel that is absent of high priority uplink control information has a higher priority than content associated with a low priority physical uplink channel that includes one or more of low priority hybrid automatic repeat request acknowledgment feedback, or low priority scheduling request, or low priority link recovery request, or any combination thereof.

[0104] In some examples, according to a priority hierarchy, content associated with a low priority physical uplink channel, including one or more of low priority hybrid automatic repeat request acknowledgment feedback, or low priority scheduling request, or low priority link recovery request, has a higher priority than content associated with a low priority physical uplink channel including low priority channel state information. In some examples, according to a priority hierarchy, content associated with a low priority physical uplink channel including low priority channel state information has a higher priority than content associated with a low priority physical uplink shared channel without hybrid automatic repeat request acknowledgment feedback or channel state information. In some examples, according to a priority hierarchy, content associated with a low priority physical uplink channel including low priority channel state information has a higher priority than content associated with a low priority physical uplink shared channel without uplink control information.

The memory 730 may store computer readable computer executable code 735 including instructions that, when executed by the processor 740, cause the device 705 to perform various functions described herein. The code 735 may be stored in a non-transitory computer readable medium, such as a system memory or another type of memory. In some cases, the code 735 may not be directly executable by the processor 740, but may (e.g., when compiled and executed) cause a computer to perform functions described herein. In some cases, the memory 730 may include a basic I / O system (BIOS), which may control basic hardware or software operations, such as interactions with peripheral components or devices, among other things.

In some cases, the processor 740 may be configured to operate a memory array using a memory controller. In some cases, the memory controller may be integrated into the processor 740. The processor 740 may be configured to execute computer-readable instructions stored in a memory (e.g., memory 730) to cause the device 705 to perform various functions (e.g., functions or tasks supporting power control for uplink transmit multiplexing). For example, the device 705, or a component of the device 705, may include a processor 740 and a memory 730 coupled with the processor 740, where the processor 740 and the memory 730 are configured to perform various functions described herein.

Claims

1. 1. A method for power control prioritization of wireless communications by a user equipment (UE), comprising: 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, the first priority level assigned to the multiplexed transmission being based at least in part on a priority of 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 at least in part on a content of the third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission; conducting the multiplexed transmission on the first component carrier at a first transmit power and the third uplink transmission on the second component carrier at a second transmit power, wherein the first transmit power and the second transmit power are based at least in part on the first priority level and the second priority level, respectively.

2. 2. The method of claim 1, wherein the first priority level or the second priority level, or both, are determined according to a priority hierarchy, and the first priority level assigned to the multiplexed transmission is based at least in part on a highest priority of content of the first uplink transmission and the second uplink transmission.

3. 3. The method of claim 2, wherein according to the priority hierarchy, content associated with a random access channel on a primary cell has a first priority and content associated with a sounding reference signal transmission has a second priority, the first priority having a higher priority than the second priority and a higher priority than a priority of an uplink control transmission or a priority of an uplink data transmission, or both, and the second priority having a lower priority than the priority of the uplink control transmission or the priority of the uplink data transmission, or both.

4. 3. The method of claim 2, wherein, according to the priority hierarchy, content associated with a physical uplink channel that includes one or more of a high priority hybrid automatic repeat request acknowledgment feedback, or a high priority scheduling request, or a high priority link recovery request has a higher priority than content associated with a physical uplink channel that includes high priority channel status information.

5. 3. The method of claim 2, wherein according to the priority hierarchy, content associated with a physical uplink channel that includes high priority channel condition information has a higher priority than content associated with a high priority physical uplink shared channel that does not have high priority uplink control information.

6. 3. The method of claim 2, wherein according to the priority hierarchy, content associated with a high priority physical uplink shared channel that is devoid of high priority uplink control information has a higher priority than content associated with a low priority physical uplink channel that includes one or more of a low priority hybrid automatic repeat request acknowledgment feedback, or a low priority scheduling request, or a low priority link recovery request, or any combination thereof.

7. 3. The method of claim 2, wherein, according to the priority hierarchy, content associated with a low priority physical uplink channel, including one or more of a low priority hybrid automatic repeat request acknowledgment feedback, or a low priority scheduling request, or a low priority link recovery request, has a higher priority than content associated with a low priority physical uplink channel, including low priority channel state information.

8. 3. The method of claim 2, wherein according to the priority hierarchy, content associated with a low priority physical uplink channel that includes low priority channel state information has a higher priority than content associated with a low priority physical uplink shared channel that lacks uplink control information.

9. The step of assigning the first priority level to the multiplexed transmission comprises: assigning the first priority level to a first set of symbols of the multiplexed transmission, the first set of symbols being associated with the first uplink transmission and the 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 one of the first uplink transmission or the second uplink transmission.

10. The step of performing the multiplexed transmission on the first component carrier includes:

10. The method of claim 9, comprising: performing the multiplexed transmission on the first component carrier at the first transmission power for the first set of symbols and at a third transmission power for the second set of symbols, the third transmission power being different from the first transmission power.

11. An apparatus for power control prioritization of wireless communications by a user equipment (UE), comprising: means 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, the first priority level assigned to the multiplexed transmission being based at least in part on a priority of content of the first uplink transmission and the second uplink transmission; means for assigning a second priority level to a third uplink transmission on a second component carrier based at least in part on a content of the third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission; and means for conducting the multiplexed transmission on the first component carrier at a first transmit power and the third uplink transmission on the second component carrier at a second transmit power, wherein the first transmit power and the second transmit power are based at least in part on the first priority level and the second priority level, respectively.

12. The apparatus of claim 11, further comprising means for carrying out the method of any one of claims 2 to 10.

13. A computer program comprising instructions for, when executed by a UE, carrying out a method according to any one of claims 1 to 10.
