Technical Field

[0003] In general, the present disclosure relates to communication systems, and more particularly, the present disclosure relates to wireless communication including uplink carrier aggregation. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ a multiple - access technology capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple - access technologies include code - division multiple - access (CDMA) systems, time - division multiple - access (TDMA) systems, frequency - division multiple - access (FDMA) systems, orthogonal frequency - division multiple - access (OFDMA) systems, single - carrier frequency - division multiple - access (SC - FDMA) systems, and time - division synchronous code - division multiple - access (TD - SCDMA) systems.

[0005] These multiple - access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at the urban, national, regional, and even global levels. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of the continuous mobile broadband evolution released by the Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT)), and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine - type communication (mMTC), and ultra - reliable low - latency communication (URLLC). Some aspects of 5G NR may be based on the 4G Long - Term Evolution (LTE) standard. There is a need for further improvement in 5G NR technology. These improvements may also be applicable to other multiple - access technologies and telecommunication standards that employ these technologies. Summary of the Invention

[0026] The detailed description set forth below in connection with the appended drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. For the purpose of providing a thorough understanding of the various concepts, the detailed description includes specific details. It will be apparent, however, to one of ordinary skill in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0027] Certain aspects of a telecommunications system will now be presented with reference to various apparatuses and methods. These apparatuses and methods will be described in the detailed description below and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0028] By way of example, an element, or any portion of an element, or any combination of elements can be implemented as a "processing system" including one or more processors. Examples of processors include a microprocessor, a microcontroller, a graphics processing unit (GPU), a central processing unit (CPU), an application processor, a digital signal processor (DSP), a reduced instruction set computing (RISC) processor, a system on a chip (SoC), a baseband processor, a field programmable gate array (FPGA), a programmable logic device (PLD), a state machine, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functions described throughout this disclosure. One or more processors in the processing system can execute software. Whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise, software should be broadly construed to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, execution threads, processes, functions, etc.

[0029] Accordingly, in one or more example aspects, the described functionality can be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality can be stored or encoded on a computer-readable medium as one or more instructions or code. Computer-readable media includes computer storage media. Storage media can be any available media that can be accessed by a computer. By way of example and not limitation, such computer-readable media can include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, a combination of the types of computer-readable media, or any other media capable of storing computer-executable code in the form of instructions or data structures that can be accessed by a computer.

[0030] While aspects and implementations are described herein by way of illustration of some examples, those skilled in the art will understand that additional implementations and use cases may arise in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, packaging arrangements. For example, implementations and / or uses can arise via integrated chip implementations and other non-module-component-based devices such as end-user devices, vehicles, communication devices, computing devices, industrial devices, retail / purchase devices, medical devices, artificial intelligence (AI)-enabled devices, and so on. While some examples may or may not be specific to a use case or application, there can be a wide variety of applicable scopes for the innovations described. Implementations can range from chip-level or modular components to non-modular, non-chip-level implementations and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more aspects of the innovations described. In some practical settings, devices incorporating the aspects and features described may also include additional components and features for the implementation and practice of the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily includes multiple components for analog and digital purposes (such as hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / accumulators, etc.). The innovations described herein are intended to be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc. having different sizes, shapes, and configurations.

[0031] Figure 1 FIG. 4 is a schematic diagram illustrating an example of a wireless communication system and access network 100 including base stations 102 and 180 and a UE 104. The wireless communication system (also referred to as a wireless wide area network (WWAN)) includes base stations 102, UEs 104, an evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)). The base stations 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). The macro cells include base stations. The small cells include femto cells, pico cells, and micro cells.

[0032] Some wireless communication systems may support communication between a UE and a base station on multiple aggregated component carriers (CCs). In some examples, a UE may be configured to transmit uplink signals on different carriers. For example, a UE may be configured to transmit uplink control information (UCI) on a primary CC (PCC) and may be configured to transmit uplink data on a secondary CC (SCC).

[0033] In some examples, uplink control information on a PCC can overlap with uplink data on an SCC. For example, the uplink control information and the uplink data can overlap in the time domain. In such a case, some UEs can be configured to multiplex the uplink control information onto the uplink data and use the SCC to transmit the uplink data including the multiplexed uplink control information. Some UEs can be configured to check the priorities of the uplink control information and the uplink data and modify the overlapping uplink transmission based on the priorities. For example, when the priorities are the same, the UE can multiplex the uplink control information onto the uplink data, and when the priorities are different, the UE can discard the transmission with the lower priority. Additionally, some UEs can be configured to simultaneously transmit uplink control information (on the PCC) and uplink data (on the SCC).

[0034] Aspects presented herein enable a wireless communication device (such as UE 104) to apply a configured overlapping uplink transmission mode to instances of overlapping uplink transmissions. For example, the techniques disclosed herein receive an overlapping uplink transmission configuration from a base station, the overlapping uplink transmission configuration configuring an overlapping uplink transmission mode that the UE will apply when detecting the occurrence of an overlapping uplink transmission. In some examples, the overlapping uplink transmission configuration can be based on the capabilities of the UE. For example, the UE can be a legacy UE that is capable of performing multiplexing - or priority - based techniques when detecting the occurrence of an overlapping uplink transmission. In other examples, in addition to multiplexing - or priority - based techniques, the UE may also be capable of performing simultaneous transmissions. Thus, it may be beneficial to configure the UE to apply an overlapping uplink transmission mode to overlapping uplink transmissions when detecting the occurrence thereof.

[0035] In some examples, a wireless communication device (such as UE 104) can be configured to manage one or more aspects of wireless communication by applying a transmission mode to overlapping uplink transmissions. As an example, in Figure 1 , UE 104 can include an overlapping uplink transmission component 198 configured to receive an overlapping uplink transmission configuration from a base station. The example overlapping uplink transmission component 198 can also be configured to detect the occurrence of an overlapping uplink transmission, the overlapping uplink transmission including at least a portion of uplink control information and at least a portion of uplink data that overlap in the time domain. Additionally, the example overlapping uplink transmission component 198 can be configured to transmit at least one of the uplink control information or the uplink data based on the overlapping uplink transmission configuration.

[0036] Still referring to Figure 1, in some examples, the base station 102 / 180 may be configured to manage one or more aspects of wireless communication by instructing the UE to transmit for instances of overlapping uplink transmissions. As an example, in Figure 1 , the base station 102 / 180 may include a signaling component 199 configured to send an overlapping uplink transmission configuration to the UE. The exemplary signaling component 199 may also be configured to receive uplink transmissions from the UE at least in part based on the overlapping uplink transmission configuration.

[0037] Although the following description provides examples for 5G NR, the concepts described herein may be applicable to other similar domains such as LTE, LTE-A, CDMA, GSM, and / or other wireless technologies where the UE may detect the occurrence of overlapping uplink transmissions.

[0038] The base station 102 configured for 4G LTE (collectively referred to as the evolved universal mobile telecommunications system (UMTS) terrestrial radio access network (E-UTRAN)) may interface with the EPC 160 via a backhaul link 132 (e.g., S1 interface). The base station 102 configured for 5G NR (collectively referred to as the next generation RAN (NG-RAN)) may interface with the core network 190 via a backhaul link 184. In addition to other functions, the base station 102 may also perform one or more of the following functions: transmission of user data, wireless channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), user and device tracking, radio access network information management (RIM), paging, positioning, and delivery of warning messages. The base stations 102 may communicate directly or indirectly with each other (e.g., via the EPC 160 or the core network 190) on a third backhaul link 134 (e.g., X2 interface). The first backhaul link 132, the second backhaul link 184, and the third backhaul link 134 may be wired or wireless.

[0039] Base station 102 can communicate wirelessly with UE 104. Each base station 102 among the base stations 102 can provide communication coverage for a corresponding geographical coverage area 110. There can be overlapping geographical coverage areas 110. For example, small cell 102' can have a coverage area 110' that overlaps with the coverage areas 110 of one or more macro base stations 102. A network including both small cells and macro cells can be referred to as a heterogeneous network. The heterogeneous network can also include a Home evolved Node B (eNB) (HeNB), and the HeNB can provide services to a restricted group called a Closed Subscriber Group (CSG). The communication link 120 between the base station 102 and the UE 104 can include an uplink (UL) (also referred to as a reverse link) transmission from the UE 104 to the base station 102 and / or a downlink (DL) (also referred to as a forward link) transmission from the base station 102 to the UE 104. The communication link 120 can use multiple-input multiple-output (MIMO) antenna technology, which includes spatial multiplexing, beamforming, and / or transmit diversity. The communication link can be over one or more carriers. The base station 102 / UE 104 can use a spectrum with a bandwidth of up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) per carrier, allocated in carrier aggregation with a total of up to Yx MHz (x component carriers) for transmission in each direction. The carriers can be adjacent to each other or can be non-adjacent to each other. The allocation of carriers can be asymmetric with respect to DL and UL (e.g., more or fewer carriers can be allocated for DL compared to UL). The component carriers can include a primary component carrier and one or more secondary component carriers. The primary component carrier can be referred to as the Primary Cell (PCell), and the secondary component carriers can be referred to as Secondary Cells (SCells).

[0040] Some UEs 104 can communicate with each other using device-to-device (D2D) communication links 158. The D2D communication links 158 can use DL / UL WWAN spectrum. The D2D communication links 158 can use one or more sidelink channels, such as the Physical Sidelink Broadcast Channel (PSBCH), the Physical Sidelink Discovery Channel (PSDCH), the Physical Sidelink Shared Channel (PSSCH), and the Physical Sidelink Control Channel (PSCCH). D2D communication can be through various wireless D2D communication systems, such as, for example, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

[0041] The wireless communication system may further include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154 in, for example, the 5 GHz unlicensed spectrum. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) before communication to determine whether the channel is available.

[0042] The small cell 102' may operate in licensed and / or unlicensed spectrum. When operating in the unlicensed spectrum, the small cell 102' may adopt NR and use the same unlicensed spectrum (such as 5 GHz, etc.) as used by the Wi-Fi AP 150. The small cell 102' adopting NR in the unlicensed spectrum may enhance the coverage of the access network and / or increase the capacity of the access network.

[0043] The electromagnetic spectrum is generally subdivided into various categories, frequency bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating frequency bands have been identified as the frequency range names FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). Although a part of FR1 is greater than 6 GHz, FR1 is generally (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. A similar naming issue sometimes occurs with FR2. Although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) identified by the International Telecommunication Union (ITU) as the "millimeter wave" band, FR2 is generally (interchangeably) referred to as the "millimeter wave" band in documents and articles.

[0044] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating frequency bands for these mid-band frequencies as the frequency range name FR3 (7.125 GHz - 24.25 GHz). The frequency bands falling within FR3 may inherit FR1 characteristics and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to the mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating frequency bands have been identified as the frequency range names FR2-2 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0045] In view of the above aspects, unless otherwise specifically stated, if terms such as "below 6 GHz" are used herein, it should be understood that they can broadly represent frequencies that can be less than 6 GHz, can be within FR1, or can include intermediate band frequencies. Additionally, unless otherwise specifically stated, if terms such as "millimeter wave" are used herein, it should be understood that they can broadly represent frequencies that can include intermediate band frequencies, can be within FR2, FR4, FR2-2, and / or FR5, or can be within the EHF band.

[0046] Base station 102 (whether it is a small cell 102' or a large cell (e.g., a macro base station)) can include and / or be referred to as an eNB, a gNodeB (gNB), or another type of base station. Some base stations (such as gNB 180) can operate in the traditional below 6 GHz spectrum, at millimeter wave frequencies, and / or near millimeter wave frequencies to communicate with UE 104. When gNB 180 operates at millimeter wave or near millimeter wave frequencies, gNB 180 can be referred to as a millimeter wave base station. Millimeter wave base station 180 can utilize beamforming 182 with UE 104 to compensate for extremely high path loss and short distances. Base station 180 and UE 104 can each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming.

[0047] Base station 180 can transmit beamforming signals to UE 104 in one or more transmission directions 182'. UE 104 can receive beamforming signals from base station 180 in one or more reception directions 182". UE 104 can also transmit beamforming signals to base station 180 in one or more transmission directions. Base station 180 can receive beamforming signals from UE 104 in one or more reception directions. Base station 180 / UE 104 can perform beam training to determine the optimal reception and transmission directions for each of base station 180 / UE 104. The transmission direction and reception direction for base station 180 can be the same or can be different. The transmission direction and reception direction for UE 104 can be the same or can be different.

[0048] The EPC 160 may include a Mobility Management Entity (MME) 162, other MMEs 164, a Serving Gateway 166, a Multimedia Broadcast Multicast Service (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC) 170, and a Packet Data Network (PDN) Gateway 172. The MME 162 may communicate with a Home Subscriber Server (HSS) 174. The MME 162 is a control node that processes signaling between the UE 104 and the EPC 160. Generally, the MME 162 provides bearer and connection management. All User Internet Protocol (IP) packets are transported through the Serving Gateway 166, which itself is connected to the PDN Gateway 172. The PDN Gateway 172 provides IP address allocation to the UE, as well as other functions. The PDN Gateway 172 and the BM-SC 170 are connected to an IP service 176. The IP service 176 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a PS streaming service, and / or other IP services. The BM-SC 170 may provide functions for MBMS user service provisioning and delivery. The BM-SC 170 may serve as an entry point for MBMS transmissions for content providers, may be used to authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and may be used to schedule MBMS transmissions. The MBMS Gateway 168 may be used to distribute MBMS services to base stations 102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area for a particular service being broadcast, and may be responsible for session management (start / stop) and for collecting charging information related to eMBMS.

[0049] The core network 190 may include an Access and Mobility Management Function (AMF) 192, other AMFs 193, a Session Management Function (SMF) 194, and a User Plane Function (UPF) 195. The AMF 192 may communicate with a Unified Data Management Unit (UDM) 196. The AMF 192 is a control node that processes signaling between the UE 104 and the core network 190. Generally, the AMF 192 provides QoS flow and session management. All User Internet Protocol (IP) packets are transported through the UPF 195. The UPF 195 provides UE IP address allocation, as well as other functions. The UPF 195 is connected to an IP service 197. The IP service 197 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a Packet Switched (PS) Streaming Service (PSS), and / or other IP services.

[0050] A base station may include and / or be referred to as a gNB, Node B, eNB, access point, base station transceiver, radio base station, radio transceiver, transceiver functional unit, basic service set (BSS), extended service set (ESS), transmission and reception point (TRP), or some other suitable term. Base station 102 provides an access point to the EPC 160 or the core network 190 for the UE 104. Examples of the UE 104 include cellular phones, smart phones, session initiation protocol (SIP) phones, laptop computers, personal digital assistants (PDAs), satellite radio units, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electricity meters, gas pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other device with a similar function. Some of the UEs in the UE 104 may be referred to as IoT devices (e.g., parking meters, gas pumps, ovens, vehicles, cardiac monitors, etc.). The UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio device, radio communication device, remote device, mobile subscriber station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or some other suitable term. In some scenarios, the term UE may also apply to one or more companion devices, such as companion devices in a device constellation. One or more of these devices may access the network jointly and / or independently access the network.

[0051] Figure 2A FIG. 200 is an example showing the first subframe within the 5G / NR frame structure. Figure 2B FIG. 230 is an example showing the DL channels within the 5G NR subframe. Figure 2C FIG. 250 is an example showing the second subframe within the 5G NR frame structure. Figure 2D FIG. 280 is an example showing the UL channels within the 5G NR subframe. The 5G NR frame structure may be frequency division duplexing (FDD), where for a particular set of subcarriers (carrier system bandwidth), the subframes within that set of subcarriers are dedicated to DL or UL, or the 5G NR frame structure may be time division duplexing (TDD), where for a particular set of subcarriers (carrier system bandwidth), the subframes within that set of subcarriers are dedicated to both DL and UL. In Figure 2A 、 2CIn the provided example, it is assumed that the 5G NR frame structure is TDD. Among them, subframe 4 is configured with slot format 28 (where mainly DL), where D is DL, U is UL, and F is flexibly used between DL / UL, and subframe 3 is configured with slot format 1 (where all are UL). Although subframes 3 and 4 are respectively shown as having slot formats 1 and 28, any specific subframe can be configured with any one of the various available slot formats 0 - 61. Slot formats 0 and 1 are all DL and UL respectively. The other slot formats 2 - 61 include a mixture of DL, UL, and flexible symbols. The UE is configured with a slot format through the received Slot Format Indicator (SFI) (configured dynamically through Downlink Control Information (DCI), or semi-statically / statically through Radio Resource Control (RRC) signaling). It should be noted that the description provided above also applies to the 5G NR frame structure as TDD.

[0052] Figures 2A - 2D The frame structure is shown, and aspects of the present disclosure can be applicable to other wireless communication technologies, which may have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 equally sized subframes (1 ms). Each subframe can include one or more slots. A subframe can also include mini-slots, and a mini-slot can include 7, 4, or 2 symbols. Each slot can include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For normal CP, each slot can include 14 symbols, and for extended CP, each slot can include 12 symbols. The symbols on the DL can be Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) symbols. The symbols on the UL can be CP-OFDM symbols (for high throughput scenarios) or Discrete Fourier Transform (DFT) spread OFDM (DFT-s-OFDM) symbols (also known as Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols) (for power-constrained scenarios; limited to single-stream transmission). The number of slots within a subframe is based on CP and numerology. Numerology defines the subcarrier spacing (SCS), and actually defines the symbol length / duration (which can be equal to 1 / SCS).

[0053] μ <![CDATA[SCSΔf = 2 μ ·15[kHz]]]> Cyclic Prefix 0 15 Normal 1 30 Normal 2 60 Normal, Extended 3 120 Normal 4 240 Normal

[0054] For normal CP (14 symbols / slot), different numerologies μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe respectively. For extended CP, numerology 2 allows 4 slots per subframe. Accordingly, for normal CP and numerology μ, there are 14 symbols / slot and 2 μ slots / subframe. The subcarrier spacing can be equal to 2 μ*15 kHz, where μ is digital scheme 0 to 4. Thus, digital scheme μ = 0 has a subcarrier spacing of 15 kHz, and digital scheme μ = 4 has a subcarrier spacing of 240 kHz. The symbol length / duration is inversely related to the subcarrier spacing. Figures 2A - 2D An example of providing normal CP (with 14 symbols per time slot) and digital scheme μ = 2 (with 4 time slots per subframe) is given. The time slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within a frame set, there may be one or more different bandwidth parts (BWPs) that are frequency division multiplexed (see Figure 2B ). Each BWP may have a specific digital scheme and CP (normal or extended).

[0055] A resource grid can be used to represent the frame structure. Each time slot may include resource blocks (RBs) (also referred to as physical RBs (PRBs)), which span 12 consecutive subcarriers. The resource grid can be divided into multiple resource elements (REs). The number of bits carried by each RE may depend on the modulation scheme.

[0056] As shown in Figure 2A , some of the REs carry reference (pilot) signals (RSs) for the UE. In some configurations, the RS may include demodulation RSs (DM-RSs) for channel estimation at the UE (indicated as R for one specific configuration, but other DM-RS configurations are possible) and / or channel state information reference signals (CSI-RSs). The RS may also include beam measurement RSs (BRSs), beam refinement RSs (BRRSs), and / or phase tracking RSs (PT-RSs).

[0057] Figure 2BShows examples of various DL channels within a subframe of a frame. The Physical Downlink Control Channel (PDCCH) carries DCI in one or more Control Channel Elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE including six Resource Element groups (REGs), each REG including 12 consecutive Resource Elements (REs) in an OFDM symbol of a Resource Block (RB). The PDCCH within a Bandwidth Part (BWP) can be referred to as a Control Resource Set (CORESET). The UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., common search space, UE-specific search space) during a PDCCH monitoring occasion on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs can be located at higher and / or lower frequencies across the channel bandwidth. The Primary Synchronization Signal (PSS) can be within symbol 2 of a specific subframe of a frame. The PSS is used by the UE 104 to determine subframe / symbol timing and the physical layer identity. The Secondary Synchronization Signal (SSS) can be within symbol 4 of a specific subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and the radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the Demodulation Reference Signal (DM-RS). The Physical Broadcast Channel (PBCH) carrying the Master Information Block (MIB) can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also referred to as an SS block (SSB)). The MIB provides the number of RBs in the system bandwidth and the System Frame Number (SFN). The Physical Downlink Channel (PDSCH) carries user data, broadcast system information not sent via the PBCH (such as System Information Blocks (SIBs)), and paging messages.

[0058] As Figure 2C shown, some of the Resource Elements (REs) carry DM-RS for channel estimation at the base station (for a specific configuration, it is indicated as R, but other DM-RS configurations are possible). The UE can send DM-RS for the Physical Uplink Control Channel (PUCCH) and DM-RS for the Physical Uplink Shared Channel (PUSCH). The PUSCH DM-RS can be sent in the previous one or two symbols of the PUSCH. The PUCCH DM-RS can be sent in different configurations depending on whether a short PUCCH or a long PUCCH is sent and according to the specific PUCCH format used. The UE can send a Sounding Reference Signal (SRS). The SRS can be sent in the last symbol of a subframe. The SRS can have a comb structure, and the UE can send the SRS on one of the combs in the comb. The SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling on the UL.

[0059] Figure 2DShows an example of various UL channels within a subframe of a frame. The PUCCH can be positioned as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as a scheduling request, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and a hybrid automatic repeat request (HARQ) acknowledgement (ACK) (HARQ-ACK) information (ACK or negative acknowledgement (NACK)) feedback. The PUSCH carries data and can additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and / or UCI.

[0060] Figure 3 Is a block diagram showing an example of a first wireless device configured to exchange wireless communications with a second wireless device. In the example shown, the first wireless device may include a base station 310, the second wireless device may include a UE 350, and the base station 310 may communicate with the UE 350 in an access network. As Figure 3 Shown, the base station 310 includes a transmit processor (TX processor 316), a transceiver 318 including a transmitter 318a and a receiver 318b, an antenna 320, a receive processor (RX processor 370), a channel estimator 374, a controller / processor 375, and a memory 376. An example UE 350 includes an antenna 352, a transceiver 354 including a transmitter 354a and a receiver 354b, an RX processor 356, a channel estimator 358, a controller / processor 359, a memory 360, and a TX processor 368. In other examples, the base station 310 and / or the UE 350 may include additional or alternative components.

[0061] In DL, IP packets from EPC 160 can be provided to the controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functions. Layer 3 includes the Radio Resource Control (RRC) layer, and layer 2 includes the Service Data Adaptation Protocol (SDAP) layer, the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Medium Access Control (MAC) layer. The controller / processor 375 provides: RRC layer functions, which are associated with: broadcasting of system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-Radio Access Technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functions, which are associated with: header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions, which are associated with: transfer of upper layer packet data units (PDUs), error correction via ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and re-ordering of RLC data PDUs; and MAC layer functions, which are associated with: mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel prioritization.

[0062] The TX processor 316 and the RX processor 370 implement Layer 1 functions associated with various signal processing functions. Layer 1, which includes the physical (PHY) layer, may include error detection of the transport channel, forward error correction (FEC) encoding / decoding of the transport channel, interleaving, rate matching, mapping onto the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. The TX processor 316 processes the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-order quadrature amplitude modulation (M-QAM)). The encoded and modulated symbols can then be split into parallel streams. Each stream can then be mapped to OFDM subcarriers, multiplexed with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then combined together using an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain OFDM symbol stream. The OFDM stream is space precoded to generate multiple spatial streams. Channel estimates from the channel estimator 374 can be used to determine the encoding and modulation schemes and for spatial processing. The channel estimates can be derived from reference signals transmitted by the UE 350 and / or channel status feedback. Each spatial stream is then provided to a different antenna 320 via a respective transmitter 318a. Each transmitter 318a can modulate a radio frequency (RF) carrier with the respective spatial stream for transmission.

[0063] At the UE 350, each receiver 354b receives signals via its respective antenna 352. Each receiver 354b recovers the information modulated onto the RF carrier and provides the information to the RX processor 356. The TX processor 368 and the RX processor 356 implement Layer 1 functions associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, the RX processor 356 can combine them into a single OFDM symbol stream. The RX processor 356 then uses a fast Fourier transform (FFT) to convert the OFDM symbol stream from the time domain to the frequency domain. The frequency-domain signal includes a respective OFDM symbol stream for each subcarrier of the OFDM signal. The symbols and reference signals on each subcarrier are recovered and demodulated by determining the most likely signal constellation points transmitted by the base station 310. These soft decisions can be based on the channel estimates calculated by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally transmitted by the base station 310 on the physical channel. The data and control signals are then provided to the controller / processor 359, which implements Layer 3 and Layer 2 functions.

[0064] The controller / processor 359 may be associated with a memory 360 that stores program code and data. The memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport channels and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets from the EPC 160. The controller / processor 359 is also responsible for error detection using the ACK and / or NACK protocols to support HARQ operations.

[0065] Similar to the functions described in connection with DL transmissions performed by the base station 310, the controller / processor 359 provides: RRC layer functions that are associated with: system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functions that are associated with: header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions that are associated with: transfer of upper layer PDUs, error correction via ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and re-ordering of RLC data PDUs; and MAC layer functions that are associated with: mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel prioritization.

[0066] Channel estimates derived by the channel estimator 358 from reference signals or feedback transmitted by the base station 310 may be used by the TX processor 368 to select an appropriate coding and modulation scheme, and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antennas 352 via respective transmitters 354a. Each transmitter 354a may modulate an RF carrier with a respective spatial stream for transmission.

[0067] At the base station 310, UL transmissions are processed in a manner similar to that described in connection with the receiver function at the UE 350. Each receiver 318b receives signals via its respective antenna 320. Each receiver 318b recovers the information modulated onto the RF carrier and provides the information to the RX processor 370.

[0068] The controller / processor 375 may be associated with a memory 376 that stores program code and data. The memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport channels and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover IP packets from the UE 350. The IP packets from the controller / processor 375 may be provided to the EPC 160. The controller / processor 375 is also responsible for supporting HARQ operations using error detection with the ACK and / or NACK protocols.

[0069] At least one of the TX processor 368, RX processor 356, and controller / processor 359 may be configured to perform aspects related to Figure 1 the overlapping uplink transmission component 198.

[0070] At least one of the TX processor 316, RX processor 370, and controller / processor 375 may be configured to perform aspects related to Figure 1 the signaling component 199.

[0071] Some wireless communication systems may support communication between a UE and a base station on multiple aggregated CCs (also referred to as "carrier aggregation"). In some examples, the UE may be configured to transmit uplink signals on different carriers. For example, the UE may be configured to transmit uplink control information (e.g., PUCCH) on the primary CC (PCC), and may be configured to transmit uplink data (e.g., PUSCH) on a secondary CC (SCC).

[0072] In some examples, the uplink control information on the PCC may overlap with the uplink data on the SCC. For example, the uplink control information and the uplink data may overlap in the time domain. Figure 4A 、 4B and 4C depict examples in which uplink control information transmission overlaps with uplink data transmission.

[0073] In some examples, when the UE detects the occurrence of overlapping uplink transmissions (e.g., when uplink control information transmission overlaps with uplink data transmission in the time domain), the UE may be configured to multiplex the uplink control information onto the uplink data (e.g., may be configured to apply a multiplexing-based transmission mode).

[0074] Figure 4A depicts example 400, where the UE may be configured to transmit a PUCCH 406 and a PUSCH 408 at time T1. As Figure 4AAs shown, PUCCH 406 and PUSCH 408 are configured for transmission on different carriers. For example, PUCCH 406 is configured for transmission on PCC 402, and PUSCH 408 is configured for transmission on SCC 404. PCC 402 can be a component carrier configured to transmit uplink control information. SCC 404 can be any component carrier different from PCC 402.

[0075] In Figure 4A the example shown, the UE can multiplex the uplink control information of PUCCH 406 onto the uplink data of PUSCH 408 to form a multiplexed PUSCH 410. Then, the UE can transmit the multiplexed PUSCH 410 including the uplink control information of PUCCH 406 on SCC 404 at time T2.

[0076] In some examples, when the UE detects the occurrence of overlapping uplink transmissions, the UE can be configured to modify the overlapping uplink transmissions based on the priorities associated with the uplink transmissions (e.g., can be configured to apply a priority-based transmission mode).

[0077] Figure 4B Depicted is illustration 420, where the UE can be configured to transmit PUCCH 422 and PUSCH 424 at time T1. Similar to Figure 4A the example, PUCCH 422 and PUSCH 424 are configured for transmission on different carriers. For example, PUCCH 422 is configured for transmission on PCC 402, and PUSCH 424 is configured for transmission on SCC 404. In the example shown, PUCCH 422 is associated with a first priority, and PUSCH 424 is associated with a second priority. In some examples, the priorities can be the same. In some examples, the priorities can be different.

[0078] In Figure 4B the example shown, when the priorities of PUCCH 422 and PUSCH 424 are different, the UE can discard the transmission with the lower priority (e.g., discard the less important transmission). For example, if the first priority associated with PUCCH 422 has a higher priority than the second priority associated with PUSCH 424, the UE can discard PUSCH 424 (associated with the lower priority). In such an example, the UE can transmit PUCCH 422 on PCC 402 at time T2.

[0079] In other examples where the second priority associated with PUSCH 424 has a higher priority than the first priority associated with PUCCH 422, the UE may discard PUCCH 422 (associated with the lower priority). In such examples, the UE may transmit PUSCH 424 on SCC 404 at time T2.

[0080] In other examples where the first priority and the second priority are the same (e.g., PUCCH 422 and PUSCH 424 are associated with the same priority), the UE may apply multiplexing. For example, the UE may multiplex the uplink control information of PUCCH 422 onto the uplink data of PUSCH 424 to form a multiplexed PUSCH 426. The UE may then transmit the multiplexed PUSCH 426 on SCC 404 at time T2.

[0081] In some examples, the UE may be able to perform simultaneous (or "parallel") transmission of uplink control information and uplink data. For example, Figure 4C Illustrated is diagram 440, where the UE may be configured to transmit PUCCH 442 and PUSCH 444 at time T1. Similar to Figure 4A and 4B the examples, PUCCH 442 and PUSCH 444 are configured for transmission on different carriers. For example, PUCCH 442 is configured for transmission on PCC 402, and PUSCH 444 is configured for transmission on SCC 404.

[0082] In Figure 4C the illustrated example, the UE may simultaneously transmit PUCCH 442 on PCC 402 at time T2 and transmit PUSCH 444 on SCC at time T2.

[0083] In Figure 4A and 4B the illustrated examples, the UE applies a non-simultaneous overlapping uplink transmission mode to overlapping uplink transmissions. For example, in Figure 4A the UE multiplexes the uplink control information of PUCCH 406 and the uplink data of PUSCH 408 into a multiplexed PUSCH 410 that is transmitted. In Figure 4B the example, the UE transmits PUCCH 422, transmits PUSCH 424, or transmits a multiplexed PUSCH 426.

[0084] Conversely, in Figure 4CIn the example, the UE is capable of simultaneously transmitting uplink control information and uplink data. For example, the UE transmits PUCCH 442 on PCC 402 and PUSCH 444 on SCC 404.

[0085] Aspects presented herein enable a wireless communication device, such as a UE, to apply a configured overlapping uplink transmission mode to instances of overlapping uplink transmissions (as Figure 4A , 4B and as shown at time T1 of 4C). For example, the techniques disclosed herein receive an overlapping uplink transmission configuration from a base station, the overlapping uplink transmission configuration configuring an overlapping uplink transmission mode that the UE will apply upon detecting the occurrence of an overlapping uplink transmission. In some examples, the overlapping uplink transmission configuration may be based on the capabilities of the UE. For example, the UE may be a legacy UE capable of performing multiplexing-based techniques (as Figure 4A shown) or priority-based techniques ( Figure 4B shown) upon detecting the occurrence of an overlapping uplink transmission. In other examples, in addition to multiplexing-based techniques and / or priority-based techniques, the UE may also be capable of performing simultaneous transmissions (as Figure 4C shown). Thus, when the UE is capable of both simultaneous and non-simultaneous overlapping uplink transmission modes, it may be beneficial to configure the UE to apply the overlapping uplink transmission mode to overlapping uplink transmissions upon detecting the occurrence of an overlapping uplink transmission.

[0086] Figure 5 FIG. shows an example communication flow 500 between base station 502 and UE 504 as presented herein. In the example shown, communication flow 500 facilitates the UE 504 in transmitting uplink transmissions by applying an overlapping uplink transmission mode configured by base station 502. Aspects of base station 502 may be implemented by Figure 1 base station 102 / 180 of Figure 3 and / or Figure 1 UE 104 of Figure 3 and / or Figure 5 UE 350 of

[0087] In some examples, UE 504 may send a capability report 510 received by base station 502. The capability report 510 may indicate whether UE 504 is a UE capable of simultaneous and non-simultaneous overlapping uplink transmission modes or a UE capable of non-simultaneous overlapping uplink transmission modes (e.g., a legacy UE). In some examples, UE 504 may send the capability report 510, for example, after performing a random access channel (RACH) procedure with base station 502.

[0088] At 512, base station 502 may determine an overlapping uplink transmission mode to configure UE 504. In some examples, base station 502 may determine the overlapping uplink transmission mode at least in part based on the capability report 510. For example, the capability report 510 may indicate that UE 504 is a legacy UE. In such an example, at 512, base station 502 may determine to configure UE 504 with a non-simultaneous overlapping uplink transmission mode, such as a multiplexing-based transmission mode (as Figure 4A shown) or a priority-based transmission mode (as Figure 4B shown).

[0089] In some examples, the capability report 510 may indicate that UE 504 is capable of simultaneous and non-simultaneous overlapping uplink transmission modes. In some such examples, at 512, base station 502 may determine to configure UE 504 with a simultaneous overlapping uplink transmission mode or a non-simultaneous overlapping uplink transmission mode. In some examples where base station 502 determines to configure UE 504 with a non-simultaneous overlapping uplink transmission mode, base station 502 may also determine to configure UE 504 with a multiplexing-based transmission mode or a priority-based transmission mode.

[0090] In Figure 5 the illustrated example, base station 502 sends a configuration 514 received by UE 504. Base station 502 may send the configuration 514 using RRC signaling, via a medium access control-control element (MAC-CE), or via DCI. The configuration 514 may configure UE 504 to apply an overlapping uplink transmission mode to the occurrence of overlapping uplink transmissions.

[0091] In some examples, the configuration 514 may include a one-bit indicator. For example, a first value (e.g., "0") may configure UE 504 to apply a non-simultaneous overlapping uplink transmission mode. In some such examples, UE 504 may determine whether to apply a multiplexing-based transmission mode or a priority-based transmission mode. A second value (e.g., "1") may configure UE 504 to apply a simultaneous overlapping uplink transmission mode.

[0092] In some examples, configuration 514 may include a two-bit indicator. For example, a first value (e.g., "00") may configure UE 504 to apply a multiplexing-based transmission mode, a second value (e.g., "01") may configure UE 504 to apply a priority-based transmission mode, and a third value (e.g., "10") may configure UE 504 to apply a simultaneous overlapping uplink transmission mode.

[0093] In the example shown, at 516, UE 504 detects an overlapping uplink transmission scenario. For example, UE 504 may detect the occurrence of uplink control information transmission on a PCC and uplink data transmission on an SCC that overlap in the time domain, as Figure 4A , 4B and as shown at time T1 in 4C.

[0094] As Figure 5 shown, at 518, UE 504 may apply an overlapping uplink transmission mode to the uplink transmission. At 518, UE 504 may apply the overlapping uplink transmission mode based on configuration 514. For example, UE 504 may apply a non-simultaneous overlapping uplink transmission mode (such as a multiplexing-based transmission mode or a priority-based transmission mode), or may apply a simultaneous overlapping uplink transmission mode.

[0095] In some examples, UE 504 may be configured to apply a multiplexing-based transmission mode. For example, and referring to the example of Figure 4A , UE 504 may multiplex the uplink control information of PUCCH 406 onto PUSCH 408 to generate a multiplexed PUSCH 410 that includes the uplink control information. UE 504 may then send an uplink transmission 520 that is received by base station 502. In some such examples, uplink transmission 520 may include the multiplexed PUSCH 410.

[0096] In some examples, UE 504 may be configured to apply a priority-based transmission mode. For example, and referring to the example of Figure 4B , UE 504 may compare the priorities of PUCCH 422 and PUSCH 424, and modify the overlapping uplink transmission (at time T1) based on the priorities. UE 504 may then send an uplink transmission 520 that is received by base station 502. Uplink transmission 520 may include the modified overlapping uplink transmission (at time T2).

[0097] For example, when the second priority is lower than the first priority, the UE 504 may determine to discard the PUSCH 424. In some such examples, the uplink transmission 520 may include the PUCCH 422. In some examples, when the first priority is lower than the second priority, the UE 504 may determine to discard the PUCCH 422. In some such examples, the uplink transmission 520 may include the PUSCH 424. In some examples, when the first priority and the second priority are the same (i.e., equal), the UE 504 may determine to multiplex the uplink control information of the PUCCH 422 onto the uplink data of the PUSCH 424. In some such examples, the uplink transmission 520 may include the multiplexed PUSCH 426.

[0098] In some examples, the UE 504 may be configured to apply a simultaneous overlapping uplink transmission mode. For example, and with reference to Figure 4C the example of, the UE 504 may determine to simultaneously transmit uplink control information and uplink data on different respective carriers. For example, the uplink transmission 520 may include the PUCCH 442 on the PCC 402 and include the PUSCH on the SCC 404.

[0099] Figure 6 is a flowchart 600 of a method of wireless communication. The method may be performed by a UE (e.g., UE 104, UE 350, and / or Figure 8 the apparatus 802). The method may facilitate improved communication by configuring the UE to apply an overlapping uplink transmission mode when an event of overlapping uplink transmissions occurs.

[0100] At 602, the UE receives an overlapping uplink transmission configuration from the base station, as described in connection with Figure 5 the configuration 514. Receiving the overlapping uplink transmission configuration at 602 may be performed by the configuration receiving component 840 of Figure 8 the apparatus 802. For example, the UE may receive the overlapping uplink transmission configuration via at least one of RRC signaling, MAC-CE, or DCI.

[0101] At 604, the UE detects the occurrence of an overlapping uplink transmission that includes at least a portion of uplink control information and at least a portion of uplink data that overlap in the time domain, as described in connection with Figure 5 the 516. Detecting the occurrence of the overlapping uplink transmission at 604 may be performed by the overlapping monitoring component 842 of Figure 8 the apparatus 802.

[0102] At 606, the UE transmits at least one of uplink control information or uplink data based on an overlapping uplink transmission configuration, as described in conjunction with Figure 5 the uplink transmission 520. Transmitting at least one of uplink control information or uplink data at 606 may be performed by Figure 8 the uplink transmission component 844 of the apparatus 802.

[0103] Figure 7 is a flowchart 700 of a method of wireless communication. The method may be performed by a UE (e.g., UE 104, UE 350, and / or Figure 8 the apparatus 802). The method may facilitate improved communication by configuring the UE to apply an overlapping uplink transmission mode when an event of overlapping uplink transmissions occurs.

[0104] At 704, the UE receives an overlapping uplink transmission configuration from the base station, as described in conjunction with Figure 5 the configuration 514. Receiving the overlapping uplink transmission configuration at 704 may be performed by Figure 8 the configuration receiving component 840 of the apparatus 802. For example, the UE may receive the overlapping uplink transmission configuration via at least one of RRC signaling, MAC-CE, or DCI.

[0105] At 706, the UE detects the occurrence of an overlapping uplink transmission that includes at least a portion of uplink control information and at least a portion of uplink data that overlap in the time domain, as described in conjunction with Figure 5 the 516. Detecting the occurrence of the overlapping uplink transmission at 706 may be performed by Figure 8 the overlapping monitoring component 842 of the apparatus 802.

[0106] At 724, the UE transmits at least one of uplink control information or uplink data based on the overlapping uplink transmission configuration, as described in conjunction with Figure 5 the uplink transmission 520. Transmitting at least one of uplink control information or uplink data at 724 may be performed by Figure 8 the uplink transmission component 844 of the apparatus 802.

[0107] In some examples, the overlapping uplink transmission configuration may be based on one or more capabilities associated with the UE. For example, at 702, the UE may transmit a capability report for indicating that the UE is a first UE type or a second UE type, as described in conjunction with Figure 5 the capability report 510. Transmitting the capability report at 702 may be performed by Figure 8The capability component 846 of the apparatus 802 executes. In some examples, the UE may send a capability report after performing a RACH procedure.

[0108] In some examples, a UE that is a first UE type may have the ability to apply a simultaneous overlapping uplink transmission mode (e.g., as shown in Figure 4C and a non-simultaneous overlapping uplink transmission mode (e.g., as shown in Figure 4A and 4B on overlapping uplink transmissions. A UE that is a second UE type may have the ability to apply a non-simultaneous overlapping uplink transmission mode (e.g., as shown in Figure 4A and 4B on overlapping uplink transmissions. In some examples, the received overlapping uplink configuration transmission (e.g., at 704) may be at least partially based on the capability report.

[0109] At 708, the UE may apply an overlapping uplink transmission mode on overlapping uplink transmissions, as described in 518 in connection with Figure 5 Applying the overlapping uplink transmission mode at 708 on overlapping uplink transmissions may be performed by the application component 848 of the apparatus 802 in Figure 8

[0110] In some examples, the UE may include a first UE type, and the overlapping uplink transmission configuration (e.g., received at 704) may configure the UE to apply a simultaneous overlapping uplink transmission mode on overlapping uplink transmissions. For example, at 710, the UE may apply a simultaneous overlapping uplink transmission mode on overlapping uplink transmissions by sending uplink control information (e.g., at 724) using a first CC and sending uplink data (e.g., at 724) using a second CC, as described in PUCCH 442 and PUSCH 444 in connection with Figure 4C Applying the simultaneous overlapping uplink transmission mode at 710 may be performed by the simultaneous component 850 of the apparatus 802 in Figure 8

[0111] In some examples, the UE may include a first UE type, and the overlapping uplink transmission configuration (e.g., received at 704) may configure the UE to apply a non-simultaneous overlapping uplink transmission mode on overlapping uplink transmissions. In some examples, the UE may include a second UE type, and the overlapping uplink transmission configuration (e.g., received at 704) may configure the UE to apply a non-simultaneous overlapping uplink transmission mode on overlapping uplink transmissions. For example, at 712, the UE may apply a non-simultaneous overlapping uplink transmission mode by applying a multiplexing-based transmission mode or a priority-based transmission mode, as described in connection with​​Figure 4A and 4B described. Applying the non - simultaneous overlapping uplink transmission mode at 712 can be performed by the non - simultaneous component 852 of the apparatus 802 as Figure 8 described.

[0112] In some examples, the UE can apply a multiplexing - based transmission mode by applying multiplexing to the occurrence of overlapping uplink transmissions. For example, at 714, the UE can apply the non - simultaneous overlapping transmission mode on the overlapping uplink transmission by multiplexing uplink control information onto uplink data, as described in connection with Figure 4A the multiplexed PUSCH 410 described. Multiplexing the uplink control information onto the uplink data at 714 can be performed by the multiplexing component 854 of the apparatus 802 as Figure 8 described. The UE can send (e.g., at 724) uplink data with multiplexed uplink control information.

[0113] In some examples, the UE can apply a priority - based transmission mode by comparing the priorities of uplink control information and uplink data. For example, at 716, the UE can modify the overlapping uplink transmission based on a first priority of the uplink control information and a second priority of the uplink data to apply the non - simultaneous overlapping transmission mode on the overlapping uplink transmission, as described in connection with Figure 4B described. The UE can send (e.g., at 724) the modified overlapping uplink transmission.

[0114] In some examples, at 718, when the first priority and the second priority are equal, the UE can modify the overlapping uplink transmission by multiplexing the uplink control information onto the uplink data. The UE can send (e.g., at 724) uplink data with multiplexed uplink control information, such as Figure 4B the multiplexed PUSCH 426 described.

[0115] In some examples, at 720, when the first priority is lower than the second priority, the UE can modify the overlapping uplink transmission by discarding the uplink control information. The UE can send (e.g., at 724) uplink data in the case of discarded uplink control information, such as Figure 4B the PUSCH 424 described.

[0116] In some examples, at 722, when the second priority is lower than the first priority, the UE can modify the overlapping uplink transmission by discarding the uplink data. The UE can send (e.g., at 724) uplink control information in the case of discarded uplink data, such as Figure 4B the PUCCH 422 described.

[0117] Modifying the overlapping uplink transmissions at 716, 718, 720, 722 can be performed by the modification component 856 of the apparatus 802 Figure 8 shown in FIG.

As described above, apparatus 1502 may include TX processor 368, RX processor 356, and controller / processor 359. Thus, in one configuration, the above units may be TX processor 368, RX processor 356, and controller / processor 359 configured to perform the functions recited by the above units.

[0137] Figure 9 is a flowchart 900 of a method of wireless communication. The method may be performed by a base station (e.g., base station 102 / 180, base station 310, and / or Figure 11 apparatus 1102). The method may facilitate improved communication by configuring a UE to apply an overlapping uplink transmission mode when an event of overlapping uplink transmission occurs.

[0138] At 902, the base station sends an overlapping uplink transmission configuration to the UE, as described in connection with Figure 5 configuration 514. Sending the overlapping uplink transmission configuration at 902 may be performed by Figure 11 configuration component 1140 of apparatus 1102. The base station may send the overlapping uplink transmission configuration using at least one of RRC signaling, MAC-CE, or DCI.

[0139] At 904, the base station receives an uplink transmission from the UE at least partially based on the overlapping uplink transmission configuration, as described in connection with Figure 5 uplink transmission 520. Receiving the uplink transmission at 904 may be performed by Figure 11 uplink transmission component 1142 of apparatus 1102.

[0140] Figure 10FIG. 1000 is a flowchart of a method of wireless communication. The method may be performed by a base station (e.g., base station 102 / 180, base station 310, and / or Figure 11 device 1102). The method may facilitate improved communication by configuring a UE to apply an overlapping uplink transmission mode when an event of overlapping uplink transmissions occurs.

[0141] At 1002, the base station may receive, from the UE, a capability report indicating that the UE is a first UE type or a second UE type, as described in conjunction with Figure 5 capability report 510. Receiving the capability report at 1002 may be performed by Figure 11 capability component 1144 of device 1102. In some examples, the base station may receive the capability report after performing a RACH procedure.

[0142] At 1004, the base station sends an overlapping uplink transmission configuration, as described in conjunction with Figure 5 configuration 514. Sending the overlapping uplink transmission configuration at 1004 may be performed by Figure 11 configuration component 1140 of device 1102. The base station may send the overlapping uplink transmission configuration using at least one of RRC signaling, MAC-CE, or DCI.

[0143] At 1006, the base station receives an uplink transmission from the UE, at least in part based on the overlapping uplink transmission configuration, as described in conjunction with Figure 5 uplink transmission 520. Receiving the uplink transmission at 1006 may be performed by Figure 11 uplink transmission component 1142 of device 1102.

[0144] In some examples, a UE that is a first UE type may have the ability to apply a simultaneous overlapping uplink transmission mode (e.g., as shown in Figure 4C ) and a non-simultaneous overlapping uplink transmission mode (e.g., as shown in Figure 4A and 4B ) on overlapping uplink transmissions. A UE that is a second UE type may have the ability to apply a non-simultaneous overlapping uplink transmission mode (e.g., as shown in Figure 4A and 4B ) on overlapping uplink transmissions. In some examples, the overlapping uplink configuration transmission (e.g., at 1004) may be at least in part based on the capability report.

[0145] For example, the base station may send an overlapping uplink transmission configuration (e.g., at 1004) to configure the UE to apply a simultaneous overlapping uplink transmission mode when the overlapping uplink transmission occurs if the capability report indicates that the UE is a first UE type. In some such examples, at 1008, the base station may receive an uplink transmission based on the simultaneous overlapping uplink transmission mode. For example, at 1010, the base station may use a first CC to receive uplink control information, such as Figure 4C the PUCCH 442 of. At 1012, the base station may use a second CC to receive uplink data, such as Figure 4C the PUSCH 444 of. Receiving the uplink transmission at 1008, 1010, and 1012 based on the simultaneous overlapping uplink transmission mode may be performed by Figure 11 the simultaneous component 1146 of the apparatus 1102 of.

[0146] In some examples, the base station may send an overlapping uplink transmission configuration (e.g., at 1004) to configure the UE to apply a non - simultaneous overlapping uplink transmission mode when the overlapping uplink transmission occurs if the capability report indicates that the UE is a first UE type or a second UE type. In some such examples, at 1014, the base station may receive an uplink transmission based on the non - simultaneous overlapping uplink transmission mode (e.g., based on multiplexing or based on priority). For example, at 1016, the base station may receive uplink control data multiplexed with uplink control information, such as Figure 4A the example multiplexed PUSCH 410 of. In some examples, at 1018, when the first priority associated with the uplink control information is equal to the second priority associated with the uplink data, the base station may receive uplink control data multiplexed with uplink control information, such as Figure 4B the example multiplexed PUSCH 426 of. In some examples, at 1020, when the first priority is lower than the second priority, the base station may receive uplink data, such as Figure 4B the example PUSCH 424 of. In some examples, at 1022, when the second priority is lower than the first priority, the base station may receive uplink data, such as Figure 4B the example PUCCH 422 of. Receiving the uplink transmission at 1014, 1016, 1018, 1020, 1022 based on the non - simultaneous overlapping uplink transmission mode may be performed by Figure 11 the non - simultaneous component 1148 of the apparatus 1102 of.

For example, the techniques disclosed herein receive an overlapping uplink transmission configuration from a base station, the overlapping uplink transmission configuration configuring an overlapping uplink transmission mode that a UE will apply upon detecting the occurrence of an overlapping uplink transmission. In some examples, the overlapping uplink transmission configuration may be based on the capabilities of the UE.

In other examples, in addition to multiplexing-based or priority-based techniques, the UE may also be capable of performing simultaneous transmissions. Thus, it may be beneficial to configure the UE to apply an overlapping uplink transmission mode to overlapping uplink transmissions upon detecting the occurrence of an overlapping uplink transmission.
