[0002] The following relates to wireless communication including enhanced power control for uplink transmission multiplexing.

Background Art

[0003] Wireless communication systems have been widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, etc. 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 multi-connection systems include fourth-generation (4G) systems such as Long-Term Evolution (LTE) systems, LTE Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth-generation (5G) systems sometimes referred to as New Radio (NR) systems. These systems may utilize techniques 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 multi-connection communication system may include one or more base stations or one or more network access nodes that each simultaneously support communication for a plurality of communication devices, sometimes referred to as user equipment (UE).

[0004] Some wireless systems support uplink transmission multiplexing. [Overview of the project] [Problems that the invention aims to solve]

[0005] In some cases, it is desirable to improve the effectiveness of multiplexed uplink transmission. [Means for solving the problem]

[0006] The techniques described relate to improved methods, systems, devices, and apparatus for supporting power control prioritization of wireless communications. Generally, the techniques described provide user equipment (UE) for determining power control prioritization of wireless communications. In some cases, the UE may perform multiplexed transmissions on a first uplink carrier. The multiplexed transmission may include the first uplink transmission being 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 transmission based on the priority content (e.g., the highest priority content) of the first and second uplink transmissions. Thus, the priority content, whether of the first or second uplink transmission, determines the overall priority of the multiplexed 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 multiplexed transmission. 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 UE may determine the first transmit power based on the first priority level and 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 limit, the transmit power calculated for the first and second uplink carriers may be scaled back based on the respective priority levels of the uplink multiplexed transmission and the third uplink transmission. 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 that of the first transmit power, or vice versa.

[0008] This document describes a method for user equipment (UE) to prioritize power control of wireless communications. The method may include the steps of: 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, and the first priority level assigned to the multiplexed transmission being based on the priority of the contents 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 contents of the third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission; and performing 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, the first and second transmit powers being based on the first and second priority levels, respectively.

[0009] This document describes a device for power control prioritization of wireless communications by a UE (Unified Engineer). The device may include a processor, memory coupled to the processor, and instructions stored in the memory. The processor may cause the device to perform the following instructions: 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 the priority of the contents 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 contents of the third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission; and 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, the first and second transmit powers being based on the first and second priority levels, respectively.

[0010] This document describes another device by a UE for power control prioritization of wireless communications. The device may include means for assigning a first priority level to a multiplexed transmission on a first component carrier, the multiplexed transmission comprising a first uplink transmission multiplexed with a second uplink transmission, the first priority level assigned to the multiplexed transmission being based on the priority of the contents of the first and second uplink transmissions; means for assigning a second priority level to a third uplink transmission on a second component carrier based on the contents of a third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission; and means for performing 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, the first and second transmit powers being based on a first and second priority level, respectively.

[0011] This document describes a non-temporary, computer-readable medium for storing code for power control prioritization of wireless communications 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, the first priority level assigned to the multiplexed transmission being based on the priority of the contents of the first and second uplink transmissions; assign a second priority level to a third uplink transmission on a second component carrier based on the contents of a third uplink transmission, the third uplink transmission overlapping in time with the multiplexed transmission; and 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, the first and second transmit powers being based on the first and second priority levels, respectively.

[0012] In some examples of the methods, apparatus, and non-temporary computer-readable media described herein, operations, features, means, or instructions may include: assigning a first priority level to a multiplexed transmission, which means assigning a first priority level to a first set of symbols for 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 for 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, apparatus, and non-temporary computer-readable media described herein, performing multiplexed transmission on a first component carrier may include operations, features, means, or instructions for performing multiplexed transmission on a first component carrier with a first transmission power for a first set of symbols and with a third transmission power different from the first transmission power for a second set of symbols.

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

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

[0016] In some examples of the methods, apparatus, and non-temporary computer-readable media described herein, content associated with a physical uplink channel, including one or more of high-priority hybrid auto-retransmission request acknowledgment feedback, or high-priority scheduling requests, or high-priority link recovery requests, may have a higher priority than content associated with a physical uplink channel, including high-priority channel status information, according to a priority hierarchy.

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

[0018] In some examples of the methods, apparatus, and non-temporary computer-readable media described herein, according to the priority hierarchy, content associated with a high-priority physical uplink shared channel that does not contain 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 the following: low-priority hybrid auto-retransmission request acknowledgment feedback, low-priority scheduling requests, or low-priority link recovery requests, or any combination thereof.

[0019] In some examples of the methods, apparatus, and non-temporary computer-readable media described herein, content associated with a low-priority physical uplink channel, including one or more of a low-priority hybrid auto-retransmission request acknowledgment feedback, or a low-priority scheduling request, or a low-priority link recovery request, may have a higher priority than content associated with a low-priority physical uplink channel, including low-priority channel status information, according to a priority hierarchy.

[0020] In some examples of the methods, apparatus, and non-temporary computer-readable media described herein, content associated with a low-priority physical uplink channel, including low-priority channel status information, may have a higher priority than content associated with a low-priority physical uplink shared channel that does not contain uplink control information, according to a priority hierarchy.

Best Mode for Carrying Out the Invention

[0022] This technique includes power control prioritization for wireless communication. Some systems may include two priority levels for uplink transmission (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 a priority index of 0, and LP may refer to an uplink transmission with a priority index of 1. In some cases, an uplink transmission may include an HP uplink transmission (e.g., an uplink transmission including HP content or an HP payload) and an LP uplink transmission (e.g., an uplink transmission including LP content or an LP payload). Examples of HP content may include ultra-reliable low-latency communication (URLLC) traffic. Examples of LP content may include enhanced mobile broadband (eMBB) traffic.

[0023] In some cases, an LP transmission may be dropped when it conflicts with an HP transmission (for example, when the time resources of the LP transmission overlap, at least partially, with those of the HP transmission). However, dropping a transmission can result in retransmission and a poor user experience. Therefore, some systems may multiplex uplink transmissions with different priorities into a single multiplexed transmission (for example, HP and LP uplink transmissions multiplexed into a single multiplexed transmission). In some cases, two uplink transmissions may be multiplexed using puncturing or rate matching. In some cases, the coding rate may be changed to allow both uplink transmissions to be transmitted.

[0024] In some cases, the UE may multiplex both HP and LP content into a multiplexed transmission. In some cases, the UE may multiplex both HP uplink control information (UCI) and LP UCI onto a physical uplink control channel, or multiplex HP UCI onto an LP physical uplink shared channel, or multiplex LP UCI onto an HP physical uplink shared channel. However, some systems lack techniques for determining priority between a multiplexed transmission with mixed priority and other uplink transmissions.

[0025] This technique allows a device to prioritize between multiplexed transmissions and other uplink transmissions. In particular, this technique provides enhanced power control for HP and LP uplink transmission multiplexing.

[0026] In some examples, the UE may be configured to transmit multiple physical uplink channels on the 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 to transmit two physical uplink control channels within the corresponding physical uplink control channel group.

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

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

[0029] First, aspects of this disclosure will be described in the context of wireless communication systems. These aspects will also be illustrated and described by the environment of a wireless communication system relating to power control for uplink transmit multiplexing. Furthermore, these aspects will be illustrated and described by apparatus diagrams, system diagrams, and flowcharts relating to power control for uplink transmit multiplexing.

[0030] Figure 1 shows an example of a wireless communication system 100 that supports power control for uplink transmit multiplexing, according to the 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, an LTE Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support extended broadband communication, ultra-high reliability (e.g., mission-critical) communication, low-latency communication, communication with low-cost, low-complexity devices, or any combination thereof.

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

[0032] The UE115 may be distributed across the entire coverage area 110 of the wireless communication system 100, and at least one UE115 may be fixed, mobile, or both at different times. The UE115 may be devices of different forms or with different capabilities. Several exemplary UE115 are shown in Figure 1. The UE115 described herein may be capable of communicating with various types of devices, such as other UE115, 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 Figure 1.

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

[0034] One or more of the base stations 105 described herein may include, or be referred to as, a base transceiver station, a radio base station, an access point, a radio transceiver, a node B, an e-node B (eNB), a next-generation node B or giga-node B (either of which may be called a gNB), a home node B, a home e-node B, or other preferred terms.

[0035] UE115 may include, or may be referred to as, a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other preferred term; “device” may also be referred to as a unit, station, terminal, or client, in the examples. UE115 may also include, or may 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, UE115 may include, or may be referred to as, a wireless local loop (WLL) station, an Internet of Things (IoT) device, any Internet of Things (IoE) device, or a machine-type communications (MTC) device, in the examples, or may be implemented in various items such as appliances, vehicles, meters, etc.

[0036] The UE115 described herein may be capable of communicating with other UE115s that may function as relays, as well as with various types of devices, including, among other examples, base stations 105 and network equipment, such as macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations.

[0037] UE115 and base station 105 may wirelessly communicate with each other via one or more communication links 125 over 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 communication links 125. For example, a carrier used for communication link 125 may include a portion of the radio frequency spectrum band (e.g., a bandwidth portion (BWP)) 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 collected signaling (e.g., synchronization signals, system information), control signaling to coordinate the operation for the carrier, user data, or other signaling. The wireless communication system 100 may support communication with UE115 using carrier aggregation or multi-carrier operation. UE115 may consist of multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used with both frequency-division duplex (FDD) component carriers and time-division duplex (TDD) component carriers.

[0038] In some examples (for instance, in carrier aggregation configurations), a carrier may also have collection or control signaling to coordinate its operation with other carriers. A carrier may be associated with a frequency channel (e.g., an Advanced 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 UE115. A carrier may operate in a standalone mode where initial collection and connection are performed via the carrier by the UE115, or the carrier may operate in a non-standalone mode where connection is anchored using different carriers (e.g., the same or different radio access technologies).

[0039] A communication link 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. The carrier may carry downlink communications or uplink communications (for example, in FDD mode), or may be configured to carry downlink communications and uplink communications (for example, in TDD mode).

[0040] 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 several predetermined bandwidths for the carrier of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (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 on a specific 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 UE 115 that supports simultaneous communication over carriers associated with multiple carrier bandwidths. In some examples, the serviced UE 115 may be configured to operate on a portion of the carrier bandwidth (e.g., a subband, BWP), or all of it.

[0041] The signal waveform transmitted on a carrier may consist of multiple subcarriers (for example, using multicarrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM). In systems utilizing MCM techniques, a resource element may contain 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). Therefore, the more resource elements the UE115 receives, and the higher the order of the modulation scheme, the higher the data rate of the UE115 can be. Wireless communication resources may refer to a combination of radio frequency spectral resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communication with the UE115.

[0042] One or more numerologies may be supported for a carrier, 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, UE115 may consist of multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communication for UE115 may be limited to one or more active BWPs.

[0043] The time interval for base station 105 or UE115 is, for example, T s = 1 / (Δf max ·N f It can refer to a sampling period of ) seconds, and can be expressed as a multiple of the basic time unit, where Δf max This can represent the maximum supported subcarrier interval, N fThis may represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of communication resources may be organized according to radio frames with a specified duration (e.g., 10 milliseconds (ms)). Radio frames may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0044] A frame may contain multiple sequentially numbered subframes or slots, each having the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into several slots. Alternatively, a frame may contain a variable number of slots, the number of which may depend on the subcarrier interval. A slot may contain several symbol periods (e.g., depending on the length of the cyclic prefix prepared for the symbol period). In some wireless communication systems 100, a slot may be further divided into several minislots, each containing one or more symbols. Except for the cyclic prefix, the symbol period may consist of one or more (e.g., N) symbol periods. f It may include a sampling period of (1) units. The duration of the symbol period may depend on the subcarrier interval or the frequency band of operation.

[0045] A subframe, slot, minislot, or symbol may be the minimum scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be called a transmit time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in the TTI) may be variable. Additionally or alternatively, the minimum scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0046] Physical channels can be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels can be multiplexed on a downlink carrier using, for example, one or more of the following techniques: time-division multiplexing (TDM), frequency-division multiplexing (FDM), or hybrid TDM-FDM. A control region for a physical control channel (e.g., a control resource set (core set)) may be defined by the number of symbol periods and may extend across the carrier's system bandwidth or a subset of the system bandwidth. One or more control regions (e.g., core sets) may be configured for a set of UE115s. For example, one or more of the UE115s may monitor or search for control regions for control information according to one or more search space sets, the search space sets may include one or more control channel candidates at one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with encoded 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 UE115s, and a UE-specific search space set for sending control information to a specific UE115.

[0047] In some examples, base station 105 may be mobile and therefore capable of providing communication coverage to a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but these 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. The wireless communication system 100 may include, for example, heterogeneous networks in which 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-high reliability communication, low latency communication, or various combinations thereof. For example, the wireless communication system 100 may be configured to support URLLC or mission-critical communication. The UE 115 may be designed to support ultra-high reliability, low latency, or critical functions (e.g., mission-critical functions). Ultra-high reliability 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 purposes. The terms ultra-high reliability, low latency, mission-critical, and ultra-high reliability low latency may be used interchangeably herein.

[0049] In some examples, UE115 may also be able to communicate directly with other UE115 via a device-to-device (D2D) communication link 135 (for example, using a peer-to-peer (P2P) protocol or a D2D protocol). One or more UE115s utilizing D2D communication may be within the geographical coverage area 110 of base station 105. Other UE115s in such a group may be outside the geographical coverage area 110 of base station 105, or in some cases may not be able to receive transmissions from base station 105. In some examples, a group of UE115s communicating via D2D communication may use a one-to-many (1:M) system in which at least one UE115 transmits to one or more other (for example, all other) UE115s in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication takes place between UE115s without the involvement of base station 105.

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

[0051] Some of the network devices, such as the base station 105, may include sub-components such as an access network entity 140, which may be an example of an access node controller (ANC). An access network entity 140 (for example, each access network entity 140) may communicate with the UE 115 through one or more other access network transmit entities 145, which may be called radio heads, smart radio heads, or transmit / receive points (TRPs). An access network transmit entity 145 may include one or more antenna panels. In some configurations, the various functions of the access network entities 140 (for example, each access network entity 140) or the base station 105 may be distributed across various network devices (for example, radio heads and ANCs) or integrated into a single network device (for example, the base station 105).

[0052] The wireless communication system 100 may operate using one or more frequency bands (for example, in the range of 300 megahertz (MHz) to 300 gigahertz (GHz)). Generally, the region from 300 MHz to 3 GHz is called the ultra-high frequency (UHF) region or decimeter band, as the wavelengths range from approximately 1 decimeter to 1 meter. Although UHF waves may be blocked or redirected by building and environmental characteristics, their waves can penetrate structures well enough for a macrocell to service an indoor UE 115. Transmitting UHF waves may involve smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmitting using lower frequencies and longer waves in the shortwave (HF) or very high frequency (VHF) portion 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), unlicensed LTE (LTE-U) radio access technology, or NR technology in unlicensed 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 may utilize carrier detection for collision detection and avoidance. In some examples, operation in unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating in licensed bands (e.g., LAA). Operation in unlicensed spectrums may include, among other examples, downlink transmission, uplink transmission, P2P transmission, or D2D transmission.

[0054] Base station 105 or UE115 may be equipped with multiple antennas that can be used to utilize techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE115 may be located in one or more antenna arrays or antenna panels that can support MIMO operation or transmit beamforming or receive beamforming. For example, one or more base station antennas or antenna arrays may be collated in 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 diverse geographical locations. Base station 105 may have an antenna array having several rows and columns of antenna ports that base station 105 can use to support beamforming of communication with UE115. Similarly, UE115 may have one or more antenna arrays that can support various MIMO or beamforming operations. As an addition or alternative, an antenna panel may support radio frequency beamforming for signals transmitted through antenna ports.

[0055] Beamforming, sometimes called spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used in a transmitting or receiving device (e.g., base station 105, UE115) to shape or steer 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 communicated through the antenna elements of an antenna array such that several signals propagating in a particular orientation relative to the antenna array undergo constructive interference and other signals undergo destructive interference. Coordination of signals communicated through antenna elements may include the transmitting or receiving device applying amplitude offset, phase offset, or both to the signals carried through the antenna elements associated with the device. The coordination associated with each antenna element may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting or receiving device, or to several other orientations).

[0056] UE115 and base station 105 may support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Retransmission Request (ARQ) feedback is one technique to increase the likelihood of data being correctly received on communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Retransmission Request (ARQ)). HARQ may improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise conditions). In some examples, devices may support same-slot HARQ feedback, where the device may provide HARQ feedback within a slot for data received in a previous symbol within a particular slot. In other cases, the device may provide HARQ feedback in subsequent slots or according to some other time interval.

[0057] In some cases, the UE (e.g., UE115 in Figure 1) may perform power control prioritization for 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 the first uplink transmission multiplexed with a second uplink transmission. In some cases, the first priority level assigned to the multiplexed transmission is based on the priority of the contents of the first and second uplink transmissions (e.g., the highest priority contents). In some cases, the UE may assign a second priority level to a third uplink transmission on a second component carrier based on the contents of the third uplink transmission. In some cases, the third uplink transmission overlaps with the multiplexed transmission at least partially 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 and second transmit powers are based on the first and second priority levels, respectively. In some cases, the UE may transmit a multiplexed transmission, a third uplink transmission, or both to the base station (for example, to base station 105 in Figure 1).

[0058] Figure 2 shows an example of a wireless communications subsystem 200 that supports power control for uplink transmit multiplexing, according to the examples described herein.

[0059] As shown in the figure, the wireless communication subsystem 200 may include UE115-a and base station 105-a, which may be examples of UE115 or base station 105, as described herein with reference to Figure 1. The wireless communication subsystem 200 may also include uplink 205 and uplink 210. In some cases, the wireless communication subsystem 200 may also include downlink. Base station 105-a may use the downlink to transmit control and / or data information to UE115-a. Also, UE115-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.

[0060] In some cases, UE115-a may perform power control prioritization for wireless communications between UE115-a and base station 105-a. In some cases, UE115-a may determine the priority of the content carried on each uplink transmit and then determine the transmit power for each uplink transmit based on the determined priority.

[0061] In some cases, UE115-a performing power control prioritization may include UE115-a assigning a first priority level to a multiplexed transmission 215 on the first component carrier of uplink 205. In some cases, the multiplexed transmission 215 may include the 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 and second uplink transmissions, which have 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.

[0062] In some cases, UE115-a may determine that the third uplink transmission 220 overlaps with the multiplexed transmission 215 at least partially. In some cases, based on the determined overlap, UE115-a may determine and assign a first priority level for the multiplexed transmission 215 and a second priority level for the third uplink transmission 220. In some cases, UE115-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 (for example, based on the content of the third uplink transmission 220 compared to the content of the multiplexed transmission 215).

[0063] In some cases, UE115-a may perform the multiplexed transmission 215 on the first component carrier with a first transmit power and the third uplink transmission 220 on the second component carrier with 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 and second priority levels may be based on a power control prioritization hierarchy. As shown in the figure, UE115-a may transmit the multiplexed transmission 215 to base station 105-a, or the third uplink transmission 220 to base station 105-a, or both to base station 105-a.

[0064] This technique improves the power use and efficiency of one or more devices (e.g., battery-powered devices, such as UE115 in Figure 1 or 2) by prioritizing power control of wireless communications, including multiplexed transmission, and therefore improves the user experience of one or more devices with longer battery life, improved quality of service, and improved data throughput.

[0065] Figure 3 shows an example of environment 300 supporting power control for uplink transmit multiplexing, according to the examples described herein.

[0066] In the illustrated example, environment 300 may include a multiplexed transmission 305 that includes 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 in the illustration, environment 300 may also include a third uplink transmission 310.

[0067] In the illustrated example, the multiplexed transmission 305 may include several symbols (for example, 11 symbols in the given example) which may contain 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 symbol 1 (for example, by piggybacking on it) 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 low-priority physical uplink channels 325 (for example, low-priority physical uplink shared channels (PUSCH) or low-priority physical uplink control channels (PUCCH) 325-a to 325-i) that occupy symbol 0, part 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 (for example, based on the low-priority physical uplink channels 325).

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

[0069] In some cases, the content of 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 random access channels on primary cells has a first priority (e.g., the highest overall priority), and content associated with sounding reference signal transmissions has a second priority (e.g., the lowest overall priority).

[0070] For power control prioritization, the priority of an uplink transmission may be determined by the highest priority of the content / payload included 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 (for example, 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 carrying both a low-priority and a high-priority HARQ-ACK may be determined to have the same priority as a high-priority PUCCH carrying a 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, the priority hierarchy for NR uplink transmissions, from highest priority to lowest priority, can be structured as follows: 1.1 Physical random access channel on a first-order cell, 2. PUCCH / PUSCH containing high-priority HARQ-ACK and / or high-priority SR and / or high-priority LRR (and may also contain other content, such as low-priority HARQ-ACK, low-priority CSI, etc.) 3. PUCCH / PUSCH with high priority CSI, 4. High-priority PUSCH that does not have either high-priority HARQ-ACK or high-priority CSI. 5. Low priority PUCCH / PUSCH including low priority HARQ-ACK and / or low priority SR and / or low priority LRR, 6. Low-priority PUCCH / PUSCH with low-priority CSI, 7. Low-priority pushers that do not have HARQ-ACK or CSI. 8. Transmit Sounding Reference Signal (SRS).

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

[0074] In some examples, the power control prioritization hierarchy may indicate that content including high-priority CSIs has a higher priority than content associated with high-priority physical uplink shared channels that do not include high-priority HARQ-ACK feedback and high-priority CSIs. In some examples, the power control prioritization hierarchy may indicate that content associated with high-priority physical uplink shared channels that do not include high-priority HARQ-ACK feedback and high-priority CSIs has a higher priority than content associated with low-priority physical uplink channels that include one or more of the following: low-priority HARQ-ACK feedback, 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, 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, which lacks HARQ-ACK feedback and channel state information.

[0076] In some cases, according to the power control prioritization hierarchy, a physical uplink channel with both low-priority and high-priority HARQ-ACKs may be determined to have the same priority as a high-priority physical uplink channel with HARQ-ACKs. According to the power control prioritization hierarchy, a low-priority physical uplink channel carrying high-priority HARQ-ACK feedback (for example, the low-priority physical uplink channel 325 of the multiplexed transmit 305) may be determined to have the same priority as an uplink transmit with high-priority HARQ-ACK feedback. According to the power control prioritization hierarchy, a high-priority physical uplink channel carrying low-priority HARQ-ACKs may be determined to have the same priority as a high-priority physical uplink channel without HARQ-ACKs.

[0077] This technique may involve the UE (for example, UE115 in Figure 1 or Figure 2) applying a power control prioritization hierarchy on a transmit-by-transmit basis. In some cases, a first uplink carrier may be associated with a multiplexed transmit 305, and a second uplink carrier may be associated with a third uplink transmit 310. If the UE determines that the combined transmit power of the first and second uplink carriers would exceed a defined power limit, the transmit power calculated for the first and second uplink carriers may be scaled back based on the respective priority levels of the multiplexed transmit 305 and the third uplink transmit 310. If the multiplexed transmit 305 is designated as a low-priority uplink transmit and the third uplink transmit 310 is designated as a high-priority uplink channel, or if the UE determines that the priority level of the third uplink transmit 310 exceeds the priority level of the multiplexed transmit 305, the UE may scale back the transmit power of the multiplexed transmit 305 by an amount greater than the transmit power of the third uplink transmit 310. In some cases, when the multiplexed transmit 305 and the third uplink transmit 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 transmit until its allocated power reaches its corresponding scheduled power (e.g., P1 for the multiplexed transmit 305 or P2 for the third uplink transmit 310). The UE may then allocate the remaining power (e.g., from the total available power up to P_max) to the lower-priority transmit. In some cases, when the scheduled power of the high-priority transmit exceeds P_max, the UE may allocate power (e.g., all power) to the high-priority transmit and not allocate any power to the low-priority channel (e.g., the low-priority channel may be dropped).In some cases, if 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 if 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] This technique may include the UE (for example, UE115 in Figure 1 or Figure 2) applying a power control prioritization hierarchy on a symbol-by-symbol basis (for example, 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 (for example, a high-priority uplink transmission), and a second priority different from the first priority to symbol 2 of the multiplexed transmission 305 based on the content of symbol 2 (for example, 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 determined priority. In some cases, the priority of the DMRS symbol 320 of the multiplexed transmission 305 may be equal to the priority of the highest-priority content in the multiplexed transmission 305 (for example, the priority of DMRS 320 may be equal to the priority of the HARQ-ACK feedback 315).

[0079] In some cases, 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 a 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 as a whole has no priority. Similarly, a first set of one or more symbols of a 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 as a whole has no priority. Alternatively, in some cases, priority may be determined by the traffic type of a given uplink transmission. In some cases, the multiplexed transmit 305 may be designated as a low-priority physical uplink channel overall (for example, because the multiplexed transmit 305 is associated with eMBB traffic), while the third uplink transmit 310 may be designated as a high-priority physical uplink channel overall (for example, because the third uplink transmit 310 is associated with URLLC traffic). In some cases, the UE may determine the priority of the uplink transmits. In some cases, the base station may determine the priority of the uplink transmits.

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

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

[0082] In the illustrated example, the UE may determine that the priority level of each of the contents of symbols 4 through 11 is lower than that of the contents of the third uplink transmission 310. Therefore, 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 over symbols 4 through 11 of the multiplexed transmission 305 in terms of transmit power (for example, according to the respective priority levels on a symbol-by-symbol basis, more transmit power may be allocated to the third uplink transmission 310 than to symbols 4 through 11 of the multiplexed transmission 305).

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

[0084] Figure 4 shows a block diagram 400 of a device 405 supporting power control for uplink transmit multiplexing, according to an example described herein. Device 405 may be an example of an embodiment 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 one another (for example, via one or more buses).

[0085] The receiver 410 may provide means for receiving 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 transmit multiplexing). The information may be passed to other components of device 405. The receiver 410 may use a single antenna or a set of multiple antennas.

[0086] The transmitter 415 may provide means for transmitting signals generated by other components of device 405. For example, the 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 transmit multiplexing). In some examples, the transmitter 415 may be collated with the receiver 410 in the transceiver module. The transmitter 415 may use a single antenna or a set of multiple antennas.

[0087] The communication manager 420, receiver 410, transmitter 415, or various combinations thereof or various components thereof may be examples of means for implementing various aspects of power control for uplink transmission multiplexing as described herein. For example, the communication manager 420, receiver 410, transmitter 415, or various combinations thereof 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 (for example, in a communications management circuit configuration). 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, which may be configured as means for performing the functions described herein or otherwise supporting such means. In some examples, the processor and memory coupled with the processor may be configured to perform one or more of the functions described herein (for example, by the processor executing instructions stored in memory).

[0089] As an addition or alternative, in some examples, the communications manager 420, receiver 410, transmitter 415, or various combinations or components thereof may be implemented in code executed by a processor (for example, as communications management software). When implemented in code executed by a processor, the functions of the communications manager 420, receiver 410, transmitter 415, or various combinations or components thereof may be implemented by any combination of a general-purpose processor, DSP, central processing unit (CPU), ASIC, FPGA, or any other programmable logic device (for example, configured as a means for performing the functions described herein, or otherwise supporting such means).

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

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

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

[0093] Figure 5 shows a block diagram 500 of a device 505 that supports power control for uplink transmit multiplexing, according to an example described herein. Device 505 may be an example of an embodiment of device 405 or UE115 as described herein. Device 505 may include a receiver 510, a transmitter 515, and a communications manager 520. Device 505 may also include a processor. Each of these components may communicate with one another (for example, via one or more buses).

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

[0095] The transmitter 515 may provide means for transmitting signals generated by other components of device 505. For example, the transmitter 515 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 transmit multiplexing). In some examples, the transmitter 515 may be collated with the receiver 510 in the transceiver module. The transmitter 515 may use a single antenna or a set of multiple antennas.

[0096] Device 505, or its various components, may be examples of means for implementing various modes of power control for uplink transmit multiplexing as described herein.

For example, communications manager 620 may include a priority manager 625, an overlap manager 630, a transmit manager 635, or any combination thereof. Each of these components may communicate with one another directly or indirectly (for example, via one or more buses).

[0099] The communications manager 620 may support power control prioritization of wireless communications by the UE, in accordance with the examples disclosed herein. The communications manager 625 may be configured as a means for assigning a first priority level to a multiplexed transmission on a first component carrier, or otherwise supporting such means, the multiplexed transmission including a first uplink transmission multiplexed with a second uplink transmission, and the first priority level assigned to the multiplexed transmission is based on the priority of the contents (e.g., highest priority contents) of the first uplink transmission and the second uplink transmission.

[0102] In some examples, a first priority level, a second priority level, or both are determined according to the priority hierarchy, and the first priority level assigned to a multiplexed transmission is based on the highest priority of the content of the first and second uplink transmissions. In some examples, according to the priority hierarchy, content associated with a random access channel on a primary cell has a first priority (e.g., highest priority), and content associated with a sounding reference signal transmission has a second priority (e.g., lowest priority).

[0103] In some cases, according to the 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 sharing channel that does not include high-priority uplink control information. In some cases, according to the priority hierarchy, content associated with a high-priority physical uplink sharing channel that does not include either high-priority hybrid auto-retransmission 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 auto-retransmission request acknowledgment feedback, low-priority scheduling requests, or low-priority link recovery requests, or any combination thereof. In some cases, according to the priority hierarchy, content associated with a high-priority physical uplink sharing channel that does not include 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 auto-retransmission request acknowledgment feedback, low-priority scheduling requests, or low-priority link recovery requests, or any combination thereof.
