Detailed Description

Carrier aggregation may be used to improve communication throughput between a network device (e.g., one or more components of a base station) and a User Equipment (UE). After carrier aggregation is enabled, a set of component carriers may be configured for the UE, including a primary component carrier (which may also be referred to as a primary cell) and one or more secondary component carriers (which may also be referred to as secondary cells). The network device may be capable of allocating communication resources to the UE on each component carrier (or subset of component carriers) and transmitting information to or receiving information from the UE on the allocated communication resources. In some examples, the network device allocates uplink communication resources on the component carriers based on an amount of uplink transmission power (which may also be referred to as power headroom) available at the UE for transmission on the component carriers (e.g., based on an indication of available uplink transmission power for different component carriers reported by the UE). In some examples, the network device may allocate uplink communication resources on component carriers having an amount of available uplink transmission power exceeding a threshold.

In some examples, the network device may limit scheduling communication resources (e.g., uplink control channel resources) for uplink control transmissions on the primary cell. However, limiting uplink control channel resources to the primary cell may delay transmission of uplink control information. Thus, the network device may be configured to support scheduling uplink control channel resources on the primary cell or one of the secondary cells. In some examples, the network device schedules uplink control channel resources on a cell (e.g., a primary cell or a secondary cell) to minimize delays in transmitting uplink control information.

However, scheduling uplink control resources on the primary or secondary cell based only on the transmission delay may not take into account whether the UE has transmission power available to transmit control information on the selected component carrier. In fact, techniques to support reporting power headroom only for control transmissions have not been established. For example, this is because the UE will report the power headroom of the data transmission on the cell (which may be referred to as a type 1 report) before being able to schedule uplink control resources on the primary or secondary cell. Or the power headroom (which may be referred to as a type 2 report) of the combined data and control transmissions on the primary cell (e.g., because the data and control transmissions may be multiplexed using data resources). Thus, a power headroom report may not be established for reporting control transmissions on the cell only. Thus, the network device may not consider the power headroom for the uplink control transmission when determining which cell is best suited to support the uplink control transmission from the UE, and the UE may exceed the maximum transmission power when performing the uplink control transmission.

In order to support scheduling of uplink control resources on the primary and secondary cells, techniques (e.g., procedures and signaling mechanisms) for reporting power headroom associated with uplink control transmissions are presented herein, considering the amount of power headroom for the uplink control transmissions. In some examples, a Power Headroom Report (PHR) may be established (which may be referred to as a type 4 report, PUCCH PHR, or control PHR) for reporting the power headroom of uplink control channel resources in a component carrier. The UE may include the control PHR report in a combined power headroom report to explicitly report the power headroom for the uplink control transmission on the component carrier. The combined power headroom report may include multiple PHR reports (e.g., including one or more data PHR and one or more control PHR for one or more component carriers).

In some examples, the network device may be able to infer the power headroom for uplink control channel resources in the cell from a power headroom report (which may be referred to as a type 1 report, PUSCH PHR, or data PHR) received for uplink data channel resources in the cell. In this case, the UE may not include the control PHR (or may include a reduced number of PHR) in the combined power headroom report. A procedure may be established for the UE to determine a combination of power headroom reports to include in the combined power headroom report sent to the network device. In some examples, combining the power headroom reports included in the power headroom report may be based on a resource allocation of the UE and a capability of the network device to infer power headroom for uplink control channel resources from the power headroom reports received for the uplink data channel resources, as described in more detail herein.

The network device may use information in the power headroom report (e.g., in combination with latency information) to determine on which component carrier to schedule uplink control channel resources, e.g., if the power headroom value for the component carrier associated with the shorter latency is negative, the network device may schedule uplink control channel resources in the component carrier associated with the longer latency.

Aspects of the present disclosure are initially described in the context of a wireless communication system. Aspects of the disclosure are also described in the context of process flows. Aspects of the disclosure are further illustrated by, and described with reference to, apparatus, system, and flow diagrams relating to controlling resource power headroom reporting.

Fig. 1 illustrates an example of a wireless communication system 100 that supports control resource power headroom reporting. 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 enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, or communications with low cost and low complexity devices, or any combination thereof.

The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may be devices of different forms or with different capabilities. The base station 105 and the UE 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the ue 115 and base station 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographic area over which base station 105 and UE 115 may support transmitting signals in accordance with one or more radio access technologies.

The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UE 115 may be a different form or device with different capabilities. Some example UEs 115 are shown in fig. 1. The UEs 115 described herein are capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated Access and Backhaul (IAB) nodes, or other network devices), as shown in fig. 1.

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

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

UE 115 may include or may 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, where "device" may also be referred to as a unit, station, terminal, client, or the like. The UE 115 may also include or be referred to as a personal electronic device, such as a cellular telephone, 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, a internet of everything (IoE) device, or a Machine Type Communication (MTC) device, etc., which may be implemented in various items such as appliances, or vehicles, meters, etc.

The UEs 115 described herein are capable of communicating with various types of devices, such as other UEs 115 that may sometimes act as relays, as well as base stations 105 and network devices, including macro enbs or gnbs, small cell enbs or gnbs, or relay base stations, among other examples, as shown in fig. 1.

The UE 115 and the base station 105 may communicate wirelessly 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 spectrum resources having a defined physical layer structure to support the communication link 125. For example, the carrier for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE-A, LTE-a Pro, NR). Each physical layer channel may carry acquisition 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.

In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. The carrier may be associated with a frequency channel, such as an evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN), and may be positioned according to a channel grid for discovery by the UE 115. The carrier may operate in an independent mode, where the UE 115 may initially acquire and connect via the carrier, or the carrier may operate in a non-independent mode where the connection is anchored using different carriers (e.g., of the same or different radio access technologies).

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

The 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 "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several determined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)) for a carrier of a particular radio access technology. 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 over a particular carrier bandwidth or may be configured to support communication over one of a set of carrier bandwidths. In some examples, wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate over a portion of the carrier bandwidth (e.g., sub-band, BWP) or the entire bandwidth.

The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as Orthogonal Frequency Division Multiplexing (OFDM) or discrete fourier transform spread OFDM (DFT-S-OFDM)). In a system employing 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 per 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 that the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate for the UE 115 can be. The wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may also increase the data rate or data integrity for communication with the UE 115.

One or more digital schemes (numerology) for carriers may be supported, where a digital scheme may include a subcarrier spacing (Δf) and a cyclic prefix. The carrier wave may be divided into one or more BWP with the same or different digital schemes. In some examples, UE 115 may be configured with multiple BWP. In some examples, a single BWP for a carrier may be active at a given time, and communication for UE 115 may be limited to one or more active BWPs.

The time interval for the base station 105 or the UE 115 may be expressed in multiples of a basic time unit, which may be referred to as T, for example _s ＝1/(Δf _max ·N _f ) Sampling period of seconds, where Δf _max The maximum supported subcarrier spacing may be represented and a maximum supported Discrete Fourier Transform (DFT) size may be represented. The time intervals of the communication resources may be organized according to radio frames, each radio frame having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

Each frame may include a plurality of consecutively numbered subframes or slots, and each subframe or slot may have 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 a number of slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on the subcarrier spacing. Each slot may include several symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of minislots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N _f A number) of sampling periods. The duration of the symbol period may depend on the subcarrier spacing or frequency band of operation.

A subframe, slot, minislot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication 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 communication system 100 may be dynamically selected (e.g., in the form of bursts of shortened TTIs (sTTIs)).

The physical channels may be multiplexed on the carrier according to various techniques. The physical control channels and physical data channels may be multiplexed on the downlink carrier using, for example, one or more of Time Division Multiplexing (TDM) techniques, frequency Division Multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. The control region (e.g., control resource set (CORESET)) for the physical control channel may be defined by a number of symbol periods and may extend across a system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., core) may be configured for the set of UEs 115. For example, one or more of UEs 115 may monitor or search the control region to obtain control information according to one or more sets of search spaces, and each set of search spaces may include one or more control channel candidates having one or more aggregation levels arranged in a cascade. The aggregation level for control channel candidates 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 set of search spaces may include a common set of search spaces configured for transmitting control information to a plurality of UEs 115 and a UE-specific set of search spaces for transmitting control information to a particular UE 115.

Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity that communicates with the base station 105 (e.g., over a carrier) and may be associated with an identifier (e.g., a Physical Cell Identifier (PCID), a Virtual Cell Identifier (VCID), or other identifier) that is used to distinguish between neighboring cells. In some examples, a cell may also refer to a geographic coverage area 110 or a portion (e.g., a sector) of geographic coverage area 110 over which a logical communication entity operates. Such cells may range from smaller areas (e.g., structures, subsets of structures) to larger areas, depending on various factors such as the capabilities of the base station 105. For example, a cell may be or include a building, a subset of buildings, or an outside space between geographic coverage areas 110 or overlapping geographic coverage areas 110, etc.

A macro cell typically covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 115 with service subscriptions with the network provider supporting the macro cell. The small cells may be associated with lower power base stations 105 than the macro cells, and the small cells may operate in the same or different (e.g., licensed, unlicensed) frequency bands than the macro cells. The small cell may provide unrestricted access to UEs 115 with service subscription with the network provider or may provide restricted access to UEs 115 with association with the small cell (e.g., UEs 115 in a Closed Subscriber Group (CSG), UEs 115 associated with users in a home or office). The base station 105 may support one or more cells and may also support communication over one or more cells using one or more component carriers.

In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

In some examples, the base station 105 may be mobile and thus provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but 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, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low latency communications (URLLC) or mission critical communications. The UE 115 may be designed to support ultra-reliable, low latency, or critical functions (e.g., mission critical functions). Ultra-reliable communications may include private communications 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 functions may include prioritization of services, and mission critical services may be used for public safety or general business applications. The terms ultra-reliable, low latency, mission critical, and ultra-reliable low latency may be used interchangeably herein.

In some examples, the UE 115 may be capable of directly communicating with other UEs 115 (e.g., using peer-to-peer (P2P) or D2D protocols) over a device-to-device (D2D) communication link 135. 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 of the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits a signal to each other UE 115 in the group. In some examples, the base station 105 facilitates scheduling of resources for D2D communications. In other cases, D2D communication is performed between UEs 115 without involving base station 105.

The core network 130 may provide user authentication, access permissions, 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 (5 GC), 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 to or interconnects to an external network. The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the core network 130. The user IP packets may be communicated by a user plane entity that may provide IP address assignment, as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. IP services 150 may include access to the internet, intranets, IP Multimedia Subsystem (IMS), or packet switched streaming services.

Some of the network devices, such as base stations 105, may include subcomponents such as access network entity 140, which access network entity 140 may be an example of an Access Node Controller (ANC). Each access network entity 140 may communicate with UEs 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmit/receive points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or incorporated into a single network device (e.g., base station 105).

The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Typically, the region from 300Mhz to 3GHz is referred to as the Ultra High Frequency (UHF) region or decimeter range, because its wavelength ranges in length from about 1 decimeter to 1 meter. UHF waves may be blocked or redirected by building and environmental features, but these waves may penetrate the building sufficiently for the macrocell to provide service to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 km) than transmission of smaller frequencies and longer wavelengths using High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum below 300 MHz.

The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ Licensed Assisted Access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency bands, such as the 5GHz industrial, scientific, and medical (ISM) frequency bands. Devices such as base station 105 and UE 115 may employ carrier sensing for collision detection and avoidance when operating in the unlicensed radio frequency spectrum band. In some examples, operation in the unlicensed band may be based on a carrier aggregation configuration that incorporates component carriers operating in the licensed band (e.g., LAA). Operations in the unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

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

Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., base station 105, UE 115) to shape or steer antenna beams (e.g., transmit beams, receive beams) along a spatial path between the transmitting device and the receiving device. Beamforming may be implemented by combining signals transmitted via antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array experience constructive interference while other signals experience destructive interference. The adjusting of the signal transmitted via the antenna element may include: the transmitting device or the receiving device applies an amplitude offset, a phase offset, or both, to the signal carried via the antenna element associated with the device. The adjustment associated with each of the antenna elements may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to an antenna array of the transmitting device or the receiving device, or relative to some other orientation).

Carrier aggregation techniques may be used to increase the amount of information that may be communicated between network devices (e.g., base station 105, one or more nodes that resolve the base station) and UE 115 over a period of time. In some examples of carrier aggregation, multiple component carriers may be configured for communication between base station 105 and UE 115, where concurrent communications may be performed on separate sets of communication resources in different component carriers. For example, the base station 105 may transmit downlink data information to the UE 115 on a first set of downlink data resources in the first component carrier and a second set of downlink data resources in the second component carrier.

In some examples, a set of component carriers is activated for UE 115, where one of the component carriers may be referred to as a primary component carrier and the remaining component carriers may be referred to as secondary component carriers. In some examples, the primary component carrier may be referred to as a primary cell or PCell and the secondary component carrier may be referred to as a secondary cell or SCell. In some examples, transmission of certain types of information (e.g., uplink control channel information, and in some examples, downlink control channel information) may be limited to the primary cell. In this case, uplink control information (e.g., HARQ information, CQI, power headroom information, etc.) generated for all component carriers in the component carrier group may be transmitted in uplink control transmission performed using uplink control channel resources scheduled in the primary cell. In some examples, the set of component carriers may be referred to as an uplink control channel set (also may be referred to as a PUCCH set). In some examples, multiple component carrier groups are activated for UE 115, where each group may include a primary cell and one or more secondary cells.

The network device may use the power headroom report to improve scheduling of uplink communication resources for the UE 115. The power headroom report may include an indication of how much transmission power is still available for additional uplink transmissions by the UE 115, taking into account how much transmission power is used by the UE 115 for the current uplink transmission. For example, the power headroom for other uplink transmissions may be determined by the power headroom from the maximum amount of transmit power (which may be denoted as P) supported by the UE 115 for uplink transmissions _MAX ) Subtracting the amount of power used for uplink data transmission (which may be denoted as P _PUSCH ) To calculate.

The power headroom report may include one (e.g., single) or multiple power headroom reports for one or more component carriers activated by the UE 115. In this case, the network device may use the power headroom report to determine on which component carriers to allocate uplink data resources to UE 115. In some examples, the network device avoids scheduling additional uplink data resources on the component carriers based on the respective power headroom reports (including zero values (indicating no available transmission power for transmission on the component carriers), negative values (indicating that the current transmission power on the component carriers exceeds the available transmission power), or positive values below a threshold (indicating that the current transmission power for transmission on the component carriers is below the available transmission power).

In some examples, the maximum amount of transmission power supported by the UE 115 may be based on the amount of power back-off the UE 115 uses for transmission, whether a maximum power reduction has been triggered, or both. The power backoff selected by the UE 115 may be based on the linear and nonlinear operating ranges of the power amplifier (e.g., the UE 115 may limit the maximum transmit power of the transmission so that the power amplifier does not (or is less likely to) enter the nonlinear range during operation). In some examples, the Maximum Power Reduction (MPR) parameter may indicate a reduction in maximum transmission power of the UE 115 based on a modulation technique used by the UE 115, a resource block allocation for the UE 115, physical channel resources used by the UE 115, or any combination thereof (e.g., to meet transmission requirements). In some examples, the additional maximum power reduction (a-MPR) may indicate an additional power reduction (relative to the maximum transmission power of UE 115) for UE 115 (e.g., in certain frequency bands or geographic areas). In some examples, the power management maximum power reduction (P-MPR) may indicate additional power reduction for the UE 115 (e.g., based on proximity of the UE 115 to the user).

In some examples, the UE 115 may determine a maximum transmission power for each component carrier activated by the UE 115, where an index of each component carrier may be represented by a variable c. In some examples, the maximum transmission power supported by UE 115 (e.g., after applying any power backoff or power reduction) may be selected by UE 115 from a range of possible maximum transmission powers. For example, a lower limit (P) of the maximum transmission power may be determined for the UE 115 based on parameters provided by the base station 105 _{CMAX_L,c} ) And an upper limit (P) of the maximum transmission power _{CMAX_H,c} ). In some examples, the lower limit P _{CMAX_L,c} The determination may be based on the following equation:

and an upper limit P _{CMAX_H,c} The determination may be based on the following equation:

in this case, the UE 115 may select (e.g., on a per component carrier basis) a maximum transmission power from a range of maximum transmission powers. In some examples, the UE 115 selects the maximum transmission power based on considerations that the base station 105 cannot acquire (e.g., is unknown) (e.g., the UE 115 may select a different maximum transmission power based on modulation order, waveform, and resource block location between control and data resources). Thus, the base station 105 may not be able to determine the maximum transmission power currently supported by the UE 115.

After selecting one or more (e.g., per carrier) maximum transmission powers, UE 115 may use the selected maximum transmission powers to determine a power headroom value for one or more component carriers (e.g., based on subtracting the transmission power allocated to transmissions on the one or more component carriers from the respective maximum transmission powers). In some examples, UE 115 determines separate power headroom reports for different types of transmissions (e.g., UE 115 may determine a power headroom value based on a data transmission, SRS transmission, or a combination of data and control transmissions). The power headroom report generated based on the scheduled transmission may be referred to as an "actual" power headroom report.

In some examples, the UE 115 may be scheduled to transmit a power headroom report when resources (or some type of resources) in one or more cells associated with the power headroom report are not scheduled (or not scheduled within a relevant time period). In this case, the UE 115 may calculate a "virtual" power headroom value and report a virtual power headroom report for one or more cells instead of an actual power headroom report. The virtual power headroom value may be generated by estimating the maximum transmission power for one or more transmission types (e.g., data channel, combined data/control channel, or SRS transmission), provided that resources for one or more transmission types are assumed to be scheduled in one resource block, and that maximum power reduction is not to be applied. Thus, the lower and upper limits for maximum power reduction may be equal (or nearly equal), and the base station 105 may be able to determine the maximum power value that the UE 115 uses to generate the virtual power headroom report.

The UE 115 may include the determined power headroom report (e.g., the actual power headroom report, the virtual power headroom report, or both) in a combined power headroom report (which may be referred to simply as a power headroom report). In some examples, UE 115 may transmit a combined power headroom report in the MAC-CE, where the combined power headroom report may include power headroom reports for multiple component carriers. The MAC-CE may include a bitmap to indicate which component carrier is associated with which power headroom report, a field to indicate whether the power headroom report is real or virtual, and a field to indicate whether the MAC entity at the UE 115 applies power backoff (e.g., due to power management).

The power headroom report may include multiple types of power headroom. For example, the power headroom report may include a type 1 power headroom indicating a difference between the maximum transmission power in the cell for the UE 115 and the estimated transmission power for the UE 115 to send uplink shared channel transmissions (which may also be referred to as PUSCH PHR or data PHR). The type 2 power headroom indicates the difference between the maximum transmission power in the cell for the UE 115 and the estimated transmission power for the UE 115 to send a combined uplink shared channel transmission and uplink control channel transmission (which may also be referred to as PUSCH/PUCCH PHR or combined data/control PHR). In some examples, the type 2 headroom report may be used to indicate the combined data and power headroom of the control transmission on the primary cell used for another MAC entity (e.g., an LTE MAC entity of UE 115 configured as E-UTRAN/New Radio Dual Connectivity (EN-DC) or New Radio/E-UTRAN Dual Connectivity (NE-DC) mode). Type 3 power headroom indicates the difference between the maximum transmission power of UE 115 and the estimated transmission power (which may also be referred to as SRS PHR) that UE 115 uses to send SRS transmissions for a cell. In some examples, the UE 115 is configured to report a separate power headroom value for each cell configured by the UE 115.

In some examples, a network device (e.g., base station 105, one or more nodes that decompose the base station) may be limited to scheduling uplink control channel resources in a primary cell. Further, in some examples, the network device may not support simultaneous transmission of uplink control information and uplink data information on separate component carriers. When simultaneous transmission is not supported, uplink control information scheduled to be transmitted on uplink control channel resources may alternatively be multiplexed with data scheduled to be transmitted on uplink data channel resources if uplink data channel resources are scheduled on one component carrier simultaneously with uplink control channel resources being scheduled on another component carrier. The multiplexed uplink data and uplink control information may then be transmitted on uplink data channel resources. In both cases, the network device or UE 115 may not use a power headroom report indicating the difference between the maximum transmission power for the UE 115 and the estimated transmission power for the uplink transmission for the cell. In this case, such power headroom reporting may not be critical. That is, for network devices that are limited to scheduling control channel resources on the primary cell, the network device may be forced to schedule uplink control resources on the primary cell regardless of the power headroom for uplink control transmissions on the primary cell. In this case, a single PHR report for data transmission on the primary cell may be used to indicate power headroom at the UE 115. Also, for wireless networks that do not support simultaneous uplink data and control transmissions on the primary and secondary cells, the network device may be configured to send both control information and data on the data channel resources, while the power headroom for uplink control transmissions on cells that include control channel resources may not be critical (e.g., because the cells may not be used).

Limiting the transmission of uplink control information for component carriers in an uplink control channel group to uplink control channel resources of the primary cell may result in introducing excessive delay in reporting of uplink control information for one or more component carriers. For example, if the primary cell uses time division multiplexing, uplink control channel resources may only occur after a set of uplink control information for one or more component carriers is generated and ready to be transmitted (even though the uplink control resources may otherwise be scheduled faster on the secondary cell). To reduce the latency associated with transmitting uplink control information on the primary cell, a network device (e.g., base station 105, one or more nodes decomposing the base station) may support a communication mode (which may be referred to as a carrier switching mode) that may enable uplink control channel resources to be scheduled on a secondary cell or primary cell in a control channel resource group (e.g., when latency is to be improved).

However, scheduling uplink control resources on the primary or secondary cell based solely on the transmission delay may not take into account whether the UE 115 has available transmission power to send control information on the component carrier. Furthermore, techniques may not be established to report power headroom for control transmissions only. Thus, the network device may not consider the power headroom when determining which cell is best suited to support uplink control transmissions from the UE 115, and the UE 115 may exceed the maximum transmission power when performing uplink control transmissions.

To support scheduling of uplink control resources on the primary and secondary cells, techniques (e.g., procedures and signaling mechanisms) for reporting power headroom associated with uplink control transmissions may be established in view of the power headroom for the uplink control transmissions. In some examples, a power headroom report (which may be referred to as a type 4 report, PUCCH PHR, or control PHR) may be established for reporting power headroom for uplink control channel resources in a component carrier. Type 4 reporting may be used to report power headroom for control transmissions on component carriers, and thus may provide power headroom information that is not transmitted for type 1 (used to transmit combined data and control transmissions on carriers), type 2 (used to transmit power headroom for data transmissions on carriers), or type 3 reporting (used to transmit power headroom for SRS transmissions on carriers). The UE 115 may include the control PHR report in a combined power headroom report to explicitly report the power headroom for the uplink control transmission on the component carrier.

In some examples, the network device may be able to infer the power headroom for uplink control channel resources in the cell from a power headroom report (which may be referred to as a type 1 report, PUSCH PHR, or data PHR) received for uplink data channel resources in the cell. In this case, the UE 115 may not include the control PHR (or may include a reduced number of PHR) in the combined power headroom report. A procedure may be established for UE 115 to determine and include a combination of power headroom reports in the combined power headroom report sent to the network device. In some examples, the combination of power headroom reports included in the combined power headroom report may be based on the resource allocation of the UE 115 and the ability of the network device to infer power headroom for uplink control channel resources from power headroom reports received for uplink data channel resources, as described in more detail herein.

The network device may use the information in the power headroom report (e.g., in combination with delay information) to determine on which component carrier to schedule uplink control channel resources (e.g., if the power headroom for the component carrier associated with the shorter delay is negative, the network device may schedule uplink control channel resources into the component carrier associated with the longer delay).

Subsystem 200 depicts base station 205 and UE 215, which may be examples of base stations (or network devices) and UEs described with reference to fig. 1. As described herein, the base station 205 and the UE 215 may communicate with each other within the coverage area 210 and on the component carrier 230.

In some examples, the base station 205 schedules uplink data resources 225 on the first component carrier 230-1 and uplink control resources 235 on the nth component carrier 230-N for the UE 215. The uplink data resources 225 may include PUSCH resources, and the uplink control resources 235 may include PUCCH resources. In some examples, control resources may be scheduled on the first component carrier 230-1 instead of the uplink data resources 225, and data resources may be scheduled on the nth component carrier 230-N instead of the uplink control resources 235. In some examples, communication resources may not be scheduled on the nth component carrier 230-N and uplink data resources 225 may continue to be scheduled on the first component carrier 230-1. In some examples, the data resources may be scheduled on the nth component carrier 230-N instead of the uplink control resources 235 and the communication resources may not be scheduled on the first component carrier 230-1.

In some examples, component carrier 230 may be included in a control channel group. In some cases, the first component carrier 230-1 may be a primary cell of a control channel group and the nth component carrier 230-N may be a secondary cell of the control channel group. In some cases, the nth component carrier 230-N may be a primary cell of a control channel group and the first component carrier 230-1 may be a secondary cell of the control channel group.

The UE 215 may be configured to determine a power headroom based on actual resources (e.g., may be referred to as an actual power headroom report), a power headroom based on virtual resources, or both. The UE 215 may determine a virtual control PHR based on the virtual control transmission on the reference control channel. In some examples, the determined virtual control PHR may be transmitted based on a reference control channel performed using a reference parameter set. The reference parameters may include a number of resource blocks (e.g., one resource block) for reference transmission, a format for a control channel (e.g., PUCCH format 0 or 1), a reference duration for PUCCH transmission (e.g., two OFDM symbols for PUCCH format 0 or 14 OFDM symbols for PUCCH format 1), a reference number scheme (e.g., 15KHz subcarrier spacing), a reference open loop power control parameter (P _{O_CUCCH} ) A reference path loss parameter (PUCCH-pathloss reference rs), a power control adjustment state index for a control channel, or any combination thereof.

In some examples, UE 215 may be based on 1) P _CMAX,f,c (i) And 2) Is calculated for control channel P _PUCCH,b,f,c (i,q _u ,q _d L) the actual power control.

In some examples, UE 215 may be based on a slave maximum transmission power value P _CMAX,f,c (i) Subtracting the virtual power control value P _PUCCH,b,f,c (i, 0) to calculate a virtual PHR, as follows:

Virtual PHR＝P _CMAX,f,c (i)-P _PUCCH,b,f,c (i,0,0,0)＝P _CMAX,f,c (i)-P _{O,PUCCH,b,f,c} (0)+PL _b,f,c (0).P _CMAX,f,c (i) It may be assumed that MPR equals 0dB, A-MPR equals 0dB, P-MPR equals 0dB, ΔT _C Equal to 0 dB. In addition, P _{O_PUCCH,b,f,c} Can be set as P _{O_PUCCH,b,f,c} (0) It may correspond to a first entry (which may be denoted as P) of the open loop power control parameter set for UE 215 _{O_UE_PUCCH} ). Further, assuming that a 15KHz subcarrier spacing is used, μ in the actual PHR equation may be set to zero. Furthermore, assuming that a single resource block control channel is used, thenCan be equal to one and thus +.>May be equal to zero. Furthermore, for downlink pathloss measurements, UE 215 may assume q _d Equal to zero, where q _d The PUCCH-pathloss reference rs-ID may be represented. UE 215 may also assume delta _{F_PUCCH} (F) Equal to zero. Furthermore, on the assumption that PUCCH format 0 or 1 is used, UE 215 may assume Δ _TF,b,f,c (i) Equal to zero, wherein if PUCCH format 0 is used, the reference duration may be equal to two OFDM symbols; if PUCCH format 1 is used, the reference duration may be equal to 14 OFDM symbols. UE 215 may also assume that the accumulated power control command is zero, thus g _b,f,c (i, l) is equal to zero, wherein the power control adjustment state index l is assumed to be zero.

In some examples, the base station 205 may be capable of inferring power headroom for control resources based on power headroom reports (e.g., data PHR) received for data resources, and vice versa. In some examples, the base station 205 may be capable of inferring a power headroom for a control resource based on a power headroom report generated by the UE 215 for an actual data resource (e.g., uplink data resource 225) or a virtual data resource, and vice versa. When inferring the power headroom based on the actual power headroom report, the base station 205 may assume that the maximum transmission power selected by the UE 215 corresponds to the upper limit of the maximum transmission power range that the UE 215 may select.

In some examples, the base station 205 may be capable of inferring a power headroom for a control resource based on a power headroom report generated by the UE 215 for a virtual data resource. When inferring a power headroom based on the virtual power headroom report, the base station 205 can determine a maximum transmission power for the UE 215 based on determining that the UE 215 has selected the maximum transmission power for generating the virtual power headroom report without applying any maximum power reduction. In some examples, the base station 205 may not be able to infer the power headroom for the control resources based on the power headroom report generated by the UE 215 for the actual or virtual data resources. In some examples, if an indication of the capability of the base station 205 is not received at the UE 215, the UE 215 may determine that the base station 205 cannot infer power headroom for one type of communication resource based on the power headroom report for another type of communication resource (whether the base station 205 is able to infer power headroom information or not).

UE 215 may prepare to incorporate PHR 220 to report power headroom for uplink data transmissions, uplink control transmissions, or both. In some examples, the UE 215 may prepare to combine the PHR 220 based on the uplink data resources 225 scheduled on the first component carrier 230-1 and the uplink control resources 235 scheduled on the nth component carrier 230-N. UE 215 may also prepare to combine PHR 220 based on either first component carrier 230-1 or nth component carrier 230-N being the primary cell. UE 215 may further prepare to incorporate PHR 220 based on the ability of base station 205 to infer the power headroom for the control channel from the power headroom report sent for the data channel, and vice versa. The UE 215 may send the combined PHR 220 to the base station 205 on uplink data resources 225.

In a first example (which may correspond to the second configuration 252 of the power headroom report shown in fig. 2B), the base station 205 may infer the power headroom for the uplink control transmission based on the actual or virtual power headroom report received for the uplink data transmission. In addition, the first component carrier 230-1 may be a primary cell and the nth component carrier 230-N may be a secondary cell. Further, a mode of scheduling control resources on the primary cell or the secondary cell (which may be referred to as a carrier switch mode) may be enabled. In some examples, control resources are scheduled onto the secondary cell only after carrier switch mode is enabled. In other examples, control resources may be scheduled on the primary cell or the secondary cell after carrier switch mode enablement (e.g., based on delay and power headroom parameters). As depicted in fig. 2A, the base station 205 may schedule uplink data resources 225 for the UE 215 on a first component carrier 230-1 and uplink control resources 235 for the UE 215 on an nth component carrier 230-N. The UE 215 may generate the combined PHR 220 to include the data PHR for the first component carrier 230-1 and the control PHR for the nth component carrier 230-N.

The UE 215 may generate a data PHR for the first component carrier 230-1 based on the uplink data resources 225 and a control PHR for the nth component carrier 230-N based on the uplink control resources 235.

The UE 215 may send the combined PHR 220 to the base station 205 using uplink data resources 225. The base station 205 may use the data PHR for the first component carrier 230-1 to determine a power headroom for an uplink control transmission on the first component carrier 230-1. The base station 205 may also use the control PHR for the nth component carrier 230-N to determine a power headroom for uplink data transmission on the nth component carrier 230-N.

In a second example (which may correspond to the first configuration 251 for power headroom reporting shown in fig. 2B), the base station 205 may infer power headroom for uplink control transmissions based on the actual or virtual power headroom report received for the uplink data transmissions. In addition, the first component carrier 230-1 may be a primary cell and the nth component carrier 230-N may be a secondary cell. Further, carrier switching mode enabling scheduling control resources on the primary cell or the secondary cell may be disabled. In this example, the base station 205 may schedule control resources for the UE 215 on the first component carrier 230-1 and schedule data resources for the UE 215 on the nth component carrier 230-N. The UE 215 may generate the combined PHR 220 to include the control PHR for the first component carrier 230-1 and the data PHR for the nth component carrier 230-N.

The UE 215 may generate a control PHR for the first component carrier 230-1 based on the control resources scheduled on the first component carrier 230-1 and generate a data PHR for the nth component carrier 230-N based on the data resources scheduled on the nth component carrier 230-N.

The UE 215 may send the combined PHR 220 to the base station 205 using the data resources scheduled on the nth component carrier 230-N. The base station 205 may use the data PHR for the nth component carrier 230-N to determine a power headroom for an uplink control transmission on the nth component carrier 230-N. Further, the base station 205 may use the control PHR for the first component carrier 230-1 to determine a power headroom for uplink data transmission on the first component carrier 230-1.

In a third example (which may correspond to the fourth configuration 254 for power headroom reporting shown in fig. 2C), the base station 205 may infer power headroom for uplink control transmissions based on the received virtual power headroom report for the uplink data transmissions. In addition, the first component carrier 230-1 may be a primary cell and the nth component carrier 230-N may be a secondary cell. A carrier switch mode capable of scheduling control resources on the primary cell or the secondary cell may be enabled. In this example, the base station 205 may schedule uplink data resources 225 for the UE 215 on the first component carrier 230-1 and schedule uplink control resources 235 for the UE 215 on the nth component carrier 230-N, as shown in fig. 2A. The UE 215 may generate the combined PHR 220 to include the data PHR and the control virtual PHR for the first component carrier 230-1, and the control PHR and the data virtual PHR for the nth component carrier 230-N.

The UE 215 may generate a data PHR for the first component carrier 230-1 based on the uplink data resources 225; generating a control virtual PHR based on the virtual control resources on the first component carrier 230-1; generating a control PHR for an nth component carrier 230-N based on the uplink control resources 235; the data virtual PHR is generated based on virtual data resources on the nth component carrier 230-N.

The UE 215 may send the combined PHR 220 to the base station 205 using uplink data resources 225. Thus, UE 215 may include each type of PHR in combined PHR 220, and base station 205 may refrain from inferring one type of PHR from another. The UE 215 may similarly generate the combined PHR 220 when the base station 205 cannot infer the power headroom of the uplink control transmission.

In a fourth example (which may correspond to the third configuration 253 for power headroom reporting shown in fig. 2C), the base station 205 may infer power headroom for uplink control transmissions based on the received virtual power headroom report for the uplink data transmissions. In addition, the first component carrier 230-1 may be a primary cell and the nth component carrier 230-N may be a secondary cell. Further, a carrier switch mode capable of scheduling control resources on the primary cell or the secondary cell may be disabled. In this example, the base station 205 may schedule control resources for the UE 215 on the first component carrier 230-1 and schedule data resources for the UE 215 on the nth component carrier 230-N. The UE 215 may generate the combined PHR 220 to include the control PHR and the data virtual PHR for the first component carrier 230-1 and the data PHR for the nth component carrier 230-N.

UE 215 may generate a control PHR for first component carrier 230-1 based on the control resources scheduled on first component carrier 230-1; generating a data virtual PHR for the first component carrier 230-1 based on the virtual data resources on the first component carrier 230-1; the data PHR for the nth component carrier 230-N is generated based on the data resources scheduled on the nth component carrier 230-N.

The UE 215 may send the combined PHR 220 to the base station 205 using the data resources scheduled on the nth portion carrier 230-N. Although UE 215 may not include every type of PHR in combined PHR 220, since carrier switching mode is disabled, base station 205 may refrain from inferring a control PHR for nth component carrier 230-N. In some examples, UE 215 may include only the data PHR for first component carrier 230-1 in combined PHR 220. The UE 215 may similarly generate the combined PHR 220 when the base station 205 cannot infer the power headroom of the uplink control transmission.

In a fifth example (which may correspond to the fifth configuration 255 for power headroom reporting shown in fig. 2C), the base station 205 may infer power headroom for uplink control transmissions based on the virtual power headroom report received for the uplink data transmission. In addition, the first component carrier 230-1 may be a primary cell and the nth component carrier 230-N may be a secondary cell. The carrier switching mode may be disabled. In this example, the base station 205 may schedule uplink data resources 225 for the UE 215 on the first component carrier 230-1 and communication resources may not be scheduled on the nth component carrier 230-N. The UE 215 may generate the combined PHR 220 to include the data PHR and the control virtual PHR for the first component carrier 230-1 and the data virtual PHR for the nth component carrier 230-N.

The UE 215 may generate a data PHR for the first component carrier 230-1 based on the uplink data resources 225; generating a control virtual PHR for the first component carrier 230-1 based on the virtual control resources on the first component carrier 230-1; and generating a data virtual PHR for the nth component carrier 230-N based on the virtual data resources on the nth component carrier 230-N.

The UE 215 may send the combined PHR 220 to the base station 205 using uplink data resources 225. Although UE 215 may not include every type of PHR in combined PHR 220, since carrier switching mode is disabled, base station 205 may avoid inferring a control PHR for nth component carrier 230-N. The UE 215 may similarly generate the combined PHR 220 when the base station 205 cannot infer the power headroom of the uplink control transmission.

In a sixth example (which may correspond to the sixth configuration 256 for power headroom reporting shown in fig. 2C), the base station 205 may infer power headroom for uplink control transmissions based on the received virtual power headroom report for the uplink data transmissions. In addition, the first component carrier 230-1 may be a primary cell and the nth component carrier 230-N may be a secondary cell. The carrier switching mode may be enabled. In this example, the base station 205 may not schedule communication resources for the UE 215 on the first component carrier 230-1, but schedule data resources for the UE 215 on the nth component carrier 230-N. The UE 215 may generate the combined PHR 220 to include the data virtual PHR for the first component carrier 230-1 and the data PHR and control virtual PHR for the nth component carrier 230-N.

The UE 215 may generate a data virtual PHR for the first component carrier 230-1 based on the virtual data resources on the first component carrier 230-1; generating a data PHR for the nth component carrier 230-N based on the scheduled data resources on the nth component carrier 230-N; the control virtual PHR is generated based on virtual control resources on the nth component carrier 230-N.

The UE 215 may send the combined PHR220 to the base station 205 using uplink data resources 225. The base station 205 may use the data virtual PHR for the first component carrier 230-1 to determine a power headroom for an uplink control transmission on the first component carrier 230-1.

In a seventh example (which may correspond to the seventh configuration 257 for power headroom reporting shown in fig. 2C), the base station 205 may infer power headroom for uplink control transmissions based on the received virtual power headroom report for the uplink data transmissions. In addition, the first component carrier 230-1 may be a primary cell and the nth component carrier 230-N may be a secondary cell. The carrier switching mode may be enabled. In this example, the base station 205 may schedule uplink data resources 225 for the UE 215 on the first component carrier 230-1 and may not schedule communication resources for the UE 215 on the nth component carrier 230-N. The UE 215 may generate the combined PHR220 to include the data PHR and the control virtual PHR for the first component carrier 230-1 and the data virtual PHR for the nth component carrier 230-N.

The UE 215 may generate a data PHR for the first component carrier 230-1 based on the uplink data resources 225; generating a control virtual PHR for the first component carrier 230-1 based on the virtual control resources on the first component carrier 230-1; a data virtual PHR for the nth component carrier 230-N is generated based on the virtual data resources on the nth component carrier 230-N.

The UE 215 may send the combined PHR 220 to the base station 205 using uplink data resources 225. The base station 205 may use the data virtual PHR for the nth component carrier 230-N to determine a power headroom for an uplink control transmission on the nth component carrier 230-N.

In an eighth example (which may correspond to the eighth configuration 258 for power headroom reporting shown in fig. 2D), the base station 205 may not infer power headroom for uplink control transmissions. In addition, the first component carrier 230-1 may be a primary cell and the nth component carrier 230-N may be a secondary cell. The carrier switching mode may be enabled. In this example, the base station 205 may not schedule communication resources for the UE 215 on the first component carrier 230-1, but schedule data resources for the UE 215 on the nth component carrier 230-N. The UE 215 may generate the combined PHR 220 to include the data virtual PHR and the control virtual PHR for the first component carrier 230-1, and the data PHR and the control virtual PHR for the nth component carrier 230-N. Thus, UE 215 may include each type of PHR in the combined PHR 220 for base station 205.

The UE 215 may generate a data virtual PHR for the first component carrier 230-1 based on the virtual data resources on the first component carrier 230-1; generating a control virtual PHR for the first component carrier 230-1 based on the virtual control resources on the first component carrier 230-1; generating a data PHR for the nth component carrier 230-N based on the scheduled data resources on the nth component carrier 230-N; the control virtual PHR is generated based on virtual control resources on the nth component carrier 230-N. The UE 215 may send the combined PHR 220 to the base station 205 using uplink data resources 225.

In a ninth example (which may correspond to the ninth configuration 259 for power headroom reporting shown in fig. 2D), the base station 205 may not infer power headroom for uplink control transmissions. In addition, the first component carrier 230-1 may be a primary cell and the nth component carrier 230-N may be a secondary cell. The carrier switching mode may be enabled. In this example, the base station 205 may schedule uplink data resources 225 for the UE 215 on the first component carrier 230-1 and may not schedule communication resources for the UE 215 on the nth component carrier 230-N. The UE 215 may generate the combined PHR 220 to include the data PHR and the control virtual PHR for the first component carrier 230-1, and the data virtual PHR and the control virtual PHR for the nth component carrier 230-N. Thus, UE 215 may include each type of PHR in the combined PHR 220 for base station 205.

The UE 215 may generate a data PHR for the first component carrier 230-1 based on the uplink data resources 225; generating a control virtual PHR for the first component carrier 230-1 based on the virtual control resources on the first component carrier 230-1; generating a data virtual PHR for the nth component carrier 230-N based on the virtual data resources on the nth component carrier 230-N; and generating a control virtual PHR based on the virtual control resources on the nth component carrier 230-N. The UE 215 may send the combined PHR 220 to the base station 205 using uplink data resources 225.

In each of the examples described above, the UE 215 may generate the combined PHR 220 such that the base station 205 provides power headroom information for both uplink control transmissions and uplink data transmissions for each component carrier 230. Or provide power headroom information for sufficient uplink control transmissions and uplink data transmissions to the base station 205 to determine (e.g., infer) the uplink control transmissions and uplink data transmissions for each component carrier 230. The UE 215 may generate sufficient power headroom information for the base station 205 to determine even when the carrier switching mode is disabled (e.g., such that the base station 205 will have power headroom information when the carrier switching mode is enabled).

Further, in the examples described above, a mode (which may be referred to as a simultaneous PUCCH/PUSCH mode) may be enabled that enables UE 215 to perform control transmission on one component carrier and data transmission on another component carrier simultaneously. In some examples, the UE 215 may send a single data PHR to the base station 205 when the carrier switch mode is enabled and control resources are scheduled on the first carrier 230-1. In this case, the UE 215 may multiplex data and control transmissions on the first carrier 230-1.

The process flow 300 may be performed by a base station 305 and a UE 315 (which may be examples of base stations (or network devices) and UEs described above with reference to fig. 1 and 2). In some examples, flow 300 illustrates an exemplary sequence of operations performed to support control resource power headroom reporting. For example, flow 300 depicts the operation of UE 315 generating and transmitting PHR to base station 305 and base station 305 scheduling resources for UE 315 based on PHR.

It should be understood that one or more of the operations described in process flow 300 may be performed earlier or later in the process, omitted, replaced, supplemented, or performed in combination with another operation. Further, additional operations described herein that are not included in process stream 300 may be included.

At arrow 320, the base station 305 and the UE 315 may exchange control signaling (e.g., RRC signaling). In some examples, the base station 305 and the UE 315 may mutually indicate the capability to support scheduling uplink control resources on the secondary cell. In some examples, the base station 305 may include an indication that a mode associated with scheduling uplink control resources on the secondary cell (e.g., a "carrier switch mode") has been activated (e.g., the base station 305 may deactivate or activate the mode using subsequent RRC, MAC layer, or PDCCH signaling). In some examples, the base station 305 and the UE 315 may mutually indicate the capability to support concurrent communications on uplink control resources in the first cell and uplink data resources in the secondary cell. In some examples, the base station 305 may include an indication that a mode (e.g., a "synchronous transmission mode") associated with concurrent control and data communications over multiple cells has been activated (e.g., the base station 305 may deactivate or activate the mode using subsequent RRC, MAC layer, or PDCCH signaling).

In some examples, the base station 305 may indicate a power headroom report schedule to the UE 315. In some examples, the base station 305 may indicate to the UE 315 the ability of the base station to infer power headroom for a communication resource (e.g., a control resource or a data resource) from power headroom reports received for other communication resources (e.g., data resources or control resources). In a first example, the base station 305 may indicate to the UE 315 the ability to infer power headroom for a communication resource based on a headroom report received for a scheduled communication resource, a headroom report received for a virtual communication resource, or both. In a second example, the base station 305 may indicate to the UE 315 the ability to infer power headroom for the communication resource based on the received headroom report for the virtual communication resource. In a third example, the base station 305 may indicate to the UE 315 that power headroom for communication resources cannot be inferred. In a fourth example, the base station 305 may not transmit the capability associated with inferring the power headroom for the communication resource, and the UE 315 may determine that the base station 305 cannot infer the power headroom for the communication resource based on not receiving an indication of the capability.

At block 325, the base station 305 may schedule communication resources for the UE 315. In some examples, the base station 305 schedules uplink data resources in a first component carrier (e.g., a primary cell or a secondary cell) and uplink control resources in a second component carrier (e.g., a secondary cell or a primary cell). In some examples, the base station 305 schedules uplink data resources in one component carrier (e.g., a primary cell or a secondary cell).

At arrow 330, the base station 305 may send an uplink grant to the UE 315. The uplink grant may indicate a location of communication resources scheduled by the base station 305 for the UE 315. In some examples, the uplink grant may also indicate whether the carrier switch mode, the synchronous transmission mode, or both are activated or deactivated. In some examples, the UE 315 may identify the resource allocation based on the uplink grant and whether the carrier switch mode or the synchronous transmission mode is activated.

At block 335, the UE 315 may generate a power headroom report based on the allocated communication resource. In some examples, the power headroom report may be further generated based on the ability of the base station 305 to infer power headroom for another communication resource based on power headroom reports received for the other communication resource.

In some examples, the base station 305 may be capable of inferring a communication resource from a power headroom report (e.g., an actual or virtual power headroom report) for another communication resource. In a first example, if the UE 315 determines to schedule control resources for the UE 315 on the primary cell, schedule data resources for the UE 315 on the secondary cell, and carrier switching is disabled, the UE 315 may generate a power headroom report including a control PHR for the primary cell and a data PHR for the secondary cell. In a second example, if the UE 315 determines to schedule data resources for the UE 315 on the primary cell, schedule control resources for the UE 315 on the secondary cell, and enable carrier switching, the UE 315 may generate a power headroom report including data PHR for the primary cell and control PHR for the secondary cell.

In some examples, the base station 305 may be capable of inferring a communication resource from a virtual power headroom report for another communication resource. In a first example, if the UE 315 determines to schedule control resources for the UE 315 on the primary cell, schedule data resources for the UE 315 on the secondary cell, and carrier switching is disabled, the UE 315 may generate a power headroom report including a control PHR and a data virtual PHR for the primary cell and a data PHR for the secondary cell. In a second example, if the UE 315 determines to schedule data resources for the UE 315 on the primary cell, control resources for the UE 315 on the secondary cell, and carrier switching is enabled, the UE 315 may generate a power headroom report including the data PHR and control virtual PHR for the primary cell and the control PHR and data virtual PHR for the secondary cell.

In a third example, if the UE 315 determines that data resources are scheduled on the primary cell for the UE 315, no communication resources are scheduled on the secondary cell for the UE 315, and carrier switching is disabled, the UE 315 may generate a data virtual PHR power headroom report including the data PHR and control virtual PHR for the primary cell and the data for the secondary cell. In a fourth example, if the UE 315 determines that communication resources are not scheduled for the UE 315 on the primary cell, data resources are scheduled for the UE 315 on the secondary cell, and carrier switching is enabled, the UE 315 may generate a power headroom report including the data virtual PHR for the primary cell and the data PHR and control virtual PHR for the secondary cell. In a fifth example, if the UE 315 determines that data resources are scheduled for the UE 315 on the primary cell, no communication resources are scheduled for the UE 315 on the secondary cell, and carrier switching is enabled, the UE 315 may generate a power headroom report including the data PHR and control virtual PHR for the primary cell and the data virtual PHR for the secondary cell.

In some examples, the base station 305 may not be able to infer a communication resource from a power headroom report for another communication resource. In a first example, if the UE 315 determines to schedule control resources for the UE 315 on the primary cell, schedule data resources for the UE 315 on the secondary cell, and carrier switching is disabled, the UE 315 may generate a power headroom report including a control PHR and a data virtual PHR for the primary cell and a data PHR for the secondary cell. In a second example, if the UE 315 determines to schedule data resources for the UE 315 on the primary cell, control resources for the UE 315 on the secondary cell, and carrier switching is enabled, the UE 315 may generate a power headroom report including the data PHR and control virtual PHR for the primary cell and the control PHR and data virtual PHR for the secondary cell.

In a third example, if the UE 315 determines that data resources are scheduled on the primary cell for the UE 315, no communication resources are scheduled on the secondary cell for the UE 315, and carrier switching is disabled, the UE 315 may generate a data virtual PHR power headroom report including the data PHR and control virtual PHR for the primary cell and the data for the secondary cell. In a fourth example, if the UE 315 determines that communication resources are not scheduled for the UE 315 on the primary cell, data resources are scheduled for the UE 315 on the secondary cell, and carrier switching is enabled, the UE 315 may generate a power headroom report including the data virtual PHR and the control virtual PHR for the primary cell and the data PHR and the control virtual PHR for the secondary cell. In a fifth example, if the UE 315 determines that data resources are scheduled on the primary cell for the UE 315, no communication resources are scheduled on the secondary cell for the UE 315, and carrier switching is enabled, the UE 315 may generate a power headroom report including the data PHR and control virtual PHR for the primary cell and the data virtual PHR and control virtual PHR for the secondary cell.

In some examples, when carrier switching is enabled and PUSCH and PUCCH resources are scheduled on the primary cell, the UE 315 may generate a power headroom report including one of a data PHR (e.g., type 1 report) or a combined data and control PHR (e.g., type 2 report) for the primary cell. If the base station 305 is able to infer a control PHR from the data PHR, the UE 315 may generate a power headroom report including the data PHR. Further, if the UE 315 multiplexes uplink data with uplink control data in an uplink transmission using the scheduled PUSCH resources, the UE 315 may generate a power headroom report based on the combined data and the control PHR. When carrier switching is enabled, PUSCH resources are scheduled on the primary cell, and PUCCH resources are scheduled on the secondary cell, the UE 315 may generate a power headroom report including at least the data PHR for the primary cell and the control PHR for the secondary cell. The base station 305 may use the control PHR to determine whether to schedule subsequent PUCCH resources for the UE 315 on the secondary cell.

In each example, the UE 315 may generate a power headroom report that includes power headroom information for enough communication resources that the UE 315 can schedule on each component carrier, such that the base station 305 can determine the power headroom information for each communication resource that the UE 315 can schedule on each component carrier. Although described in the context of two component carriers, UE 315 may also similarly generate a power headroom report reporting power headroom for more than two component carriers. Table 1 lists example combined power headroom reports, including: (1) For indicating which component carrier power headroom is being reported (using C ₁ To C ₇ ) Is a bitmap of (2); (2) An indication of whether power backoff is being applied (using the P field); (3) An indication (using the V field) of whether the corresponding power headroom report is actual or virtual; (4) a reserved field represented by an R field; and (5) power headroom reporting.

TABLE 1

At arrow 340, the UE 315 may send the generated power headroom report to the base station 305. The UE 315 may send the generated power headroom report on the uplink data resource scheduled by the base station 305.

At block 345, the base station 305 may determine power headroom information for different types of uplink transmissions on the component carriers for a plurality of component carriers configured by the UE 315. In some examples, the base station 305 may determine that no transmission power is available for uplink control transmissions by the UE 315 on the first secondary cell, but that there is available transmission power for uplink control transmissions by the UE 315 on the second secondary cell. In some examples, the base station 305 may determine that the amount of available transmission power for uplink control transmissions by the UE 315 on the first secondary cell is greater than the second secondary cell. In some examples, the base station 305 may determine that the amount of available transmission power for uplink control transmissions by the UE 315 on the primary cell is greater than any secondary cell (e.g., the base station 305 may determine that no transmission power is available for uplink control transmissions on any secondary cell.

At block 350, the base station 305 may determine a resource allocation for the UE 315 based on the determined power headroom information. In some examples, the base station 305 determines a resource allocation for uplink control of the UE 315 based on the power headroom information. For example, the base station 305 may schedule uplink control resources on the component carrier with the largest amount of available transmission power for uplink control transmission.

The base station 305 may also determine the resource allocation based on delays associated with scheduling uplink control resources in different component carriers. In some examples, the base station 305 may be configured to schedule uplink control channel resources in the first component carrier based on determining that a delay associated with scheduling uplink control resources in the first component carrier that does not have a maximum amount of available transmission power for uplink control transmissions is less than (e.g., a threshold amount) than a delay associated with scheduling uplink control resources in the component carrier associated with the maximum amount of available transmission power. For example, the base station 305 may schedule uplink control resources in a first component carrier more than 2 milliseconds ahead of scheduling uplink control resources in a second component carrier based on determining that uplink control resources may be scheduled in the first component carrier with 2dB of available transmission power instead of scheduling uplink control resources in the second component carrier with 4dB of available transmission power.

At arrow 355, the base station 305 may send a second uplink grant to the UE 315 indicating a resource allocation for the UE 315.

Fig. 4 shows a block diagram 400 of a device 405 supporting control resource power headroom reporting. The device 405 may be an example of aspects of the UE 115 as described herein. The device 405 may include a receiver 410, a transmitter 415, and a communication manager 420. The device 405 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

The receiver 410 may provide means for receiving information such as packets associated with various information channels (e.g., control channels, data channels, information channels related to control resource power headroom reporting), user data, control information, or a combination thereof. Information may be passed to other components of device 405. The receiver 410 may utilize a single antenna or may utilize a plurality of antennas of a group.

Transmitter 415 may provide a means for transmitting signals generated by other components of device 405. For example, the transmitter 415 may transmit information such as packets associated with various information channels (e.g., control channels, data channels, information channels related to control resource power headroom reporting), user data, control information, or a combination thereof. In some examples, the transmitter 415 may be co-located with the receiver 410 in a transceiver module. The transmitter 415 may utilize a single antenna or may utilize a set of multiple antennas.

The communication manager 420, the receiver 410, the transmitter 415, or various combinations thereof, or various components thereof, may be examples of means for performing aspects of controlling resource power headroom reporting as described herein. For example, communication manager 420, receiver 410, transmitter 415, or various combinations or components thereof, may support methods for performing one or more of the functions described herein.

In some examples, the communication manager 420, the receiver 410, the transmitter 415, or various combinations or components thereof may be implemented in hardware (e.g., with communication management circuitry). The hardware may include processors, digital Signal Processors (DSPs), application Specific Integrated Circuits (ASICs), field Programmable Gate Arrays (FPGAs) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or any combinations thereof, configured or otherwise supporting units for performing the functions described in the present disclosure. In some examples, a processor and a memory coupled to the processor may be configured to perform one or more of the functions described herein (e.g., by the processor executing instructions stored in the memory).

Additionally or alternatively, in some examples, the communication manager 420, the receiver 410, the transmitter 415, or various combinations or components thereof may be implemented using code executed by a processor (e.g., implemented as communication management software or firmware). If implemented in code executed by a processor, the functions of the communication 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., units configured or otherwise supporting the functions described in this disclosure).

In some examples, communication manager 420 may be configured to perform various operations (e.g., receive, monitor, transmit) using receiver 410, transmitter 415, or both, or otherwise in cooperation with receiver 410, transmitter 415, or both. For example, communication manager 420 may receive information from receiver 410, send information to transmitter 415, or be integrated with receiver 410, transmitter 415, or both to receive information, send information, or perform various other operations as described herein.

According to examples as disclosed herein, the communication manager 420 may support wireless communication at the UE. For example, the communication manager 420 may be configured or otherwise support means for receiving (e.g., from the receiver 410) a first message indicating that a plurality of component carrier sets are configured for a UE. The communication manager 420 may be configured or otherwise support means for receiving (e.g., from the receiver 410) a second message for scheduling uplink data channel resources in a first component carrier of the plurality of component carrier sets. The communication manager 420 may be configured or otherwise support means for transmitting (e.g., via the transmitter 415) a consolidated report on uplink data channel resources, the report including a first report of available transmission power for uplink data transmission on a first component carrier and a second report associated with available transmission power for uplink control channel resources on a second component carrier of the plurality of component carrier sets.

In some examples of the disclosure herein, the communication manager 420 may be configured or otherwise support means for receiving (e.g., from the receiver 410) a first message indicating that a plurality of component carrier sets are configured for a UE.
