A user equipment (UE) can determine a capability to support a Uplink Control Information (UCI) transmission mode corresponding to transmitting UCI on an uplink control channel and transmitting an uplink signal on an uplink shared channel when resources of the uplink control channel and resources of the uplink shared channel at least partially overlap. In a first UCI transmission mode, the UE can transmit UCI on the uplink control channel with resources that overlap the uplink shared channel. In another UCI transmission mode, the UE can multiplex the UCI in the uplink shared channel. A base station can transmit a configuration to the UE indicating to use a UCI transmission mode.

Description

Technical Field

[0001] In summary, the following text relates to wireless communication, and more specifically, to uplink control information (DCI) multiplexing rules for simultaneous transmission of uplink control channel and uplink shared channel. Background Technology

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (e.g., Long Term Evolution (LTE) systems, improved LTE (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems can employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication with multiple communication devices (which may also be referred to as User Equipment (UE)). Summary of the Invention

[0003] The described technology relates to improved methods, systems, devices, and apparatuses for supporting uplink control information (UCI) multiplexing rules for simultaneous uplink control channel and uplink shared channel transmission. In summary, the described technology provides a user equipment (UE) that determines the ability to support UCI transmission modes corresponding to transmitting UCI on an uplink control channel (e.g., a physical uplink control channel (PUCCH)) and uplink signals on an uplink shared channel (e.g., a physical uplink shared channel (PUSCH)) (when the resources of the PUCCH and PUSCH at least partially overlap). In some cases, the UE can execute one or more UCI transmission modes. For example, in a first UCI transmission mode, the UE can transmit UCI on a PUCCH having resources (e.g., time-frequency resources) that overlap with the PUSCH. In another UCI transmission mode, the UE can multiplex UCI in the PUSCH, and in some cases, can discard the PUCCH. In some cases, the UE can send an indication of capability to the base station. In some examples, the base station can send a configuration to the UE indicating the use of a UCI transmission mode. The UE can transmit UCI on the PUCCH and uplink signals on the PUSCH based on the configuration from the base station, which can improve the reliability (e.g., coverage) at the UE.

[0039] In some examples, a user equipment (UE) can receive one or more downlink control information (DCI) messages from a base station. For example, a UE can receive DCIs associated with uplink shared channel (e.g., Physical Uplink Shared Channel (PUSCH)) transmissions and DCIs associated with downlink shared channel (e.g., Physical Downlink Shared Channel (PDSCH)) transmissions. The UE can attempt to send uplink control information (UCIs) (e.g., feedback messages, scheduling requests, Channel State Information (CSI) reports, etc.) in response to PDSCH transmissions on the uplink control channel (e.g., Physical Uplink Control Channel (PUCCH)) and uplink signals (e.g., including control information or data) on the PUSCH. In some cases, when resources associated with the PUCCH (e.g., time-frequency resources) overlap with resources associated with the PUSCH, the UE may multiplex at least a portion of the UCI and uplink signals on the PUSCH. In other cases, resources associated with the PUCCH may not overlap with resources associated with the PUSCH. However, the UE may multiplex acknowledgment feedback information, CSI, or both in the PUSCH and may discard the PUCCH, including any other UCI that may have already been transmitted on the PUCCH, which may result in inefficient communication (e.g., due to UCI retransmissions).

[0040] As described herein, when the resources of the PUCCH and PUSCH overlap at least partially in time, the UE can determine its ability to support a UCI transmission mode corresponding to concurrently transmitting UCI on the PUCCH and uplink signals on the PUSCH, which can improve reliability (e.g., coverage) at the UE. In some cases, the UE can execute one or more UCI transmission modes. For example, in a UCI transmission mode, the UE can transmit UCI on a PUCCH with resources (e.g., time-frequency resources) overlapping with the PUSCH, and can also transmit overlapping PUSCHs. In another UCI transmission mode, the UE can multiplex UCIs within overlapping PUSCHs, and in some cases, can discard the PUCCH.

[0041] In some cases, the UE can send a capability indication to the base station. In some examples, the base station can send a configuration to the UE indicating the use of a UCI transmission mode. The UE can then transmit UCI on the PUCCH and uplink signals on the PUSCH based on the UCI transmission mode configuration from the base station. In some cases, the base station can send the configuration to the UE via RRC signaling. In some examples, if the serving cell of the PUCCH is not configured with a Transmission Control Information (TCI) state (e.g., the PUCCH may lack beam configuration), the UE can receive the RRC configuration from the base station. In some cases, the PUCCH and PUSCH can be associated with the same serving cell. In other cases, the PUCCH and PUSCH can be associated with different serving cells.

[0042] The various aspects of this disclosure are first described within the context of a wireless communication system. Additional aspects of this disclosure are described with reference to processing timelines and process flows. These aspects are further illustrated by apparatus diagrams, system diagrams, and flowcharts relating to UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmission, and are described with reference to these diagrams.

[0043] Figure 1Examples of a wireless communication system 100 supporting UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmissions according to various aspects of this disclosure are shown. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an improved LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices, or any combination thereof.

[0044] Base stations 105 can be distributed throughout a geographical area to form a wireless communication system 100, and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 on the coverage area 110. Coverage area 110 can be an example of a geographical area where base station 105 and UE 115 can support signal transmission according to one or more radio access technologies.

[0045] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be devices of different forms or with different capabilities. Figure 1 Some example UE 115s are shown in the document. The UE 115 described herein is capable of communicating with various types of devices, such as other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as... Figure 1 As shown.

[0046] Base station 105 can communicate with core network 130, communicate with each other, or perform both of these operations. For example, base station 105 can interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) on backhaul links 120 (e.g., via X2, Xn, or other interfaces), or indirectly (e.g., via core network 130), or perform both of these operations. In some examples, backhaul link 120 can be or includes one or more radio links.

[0047] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, node B, evolved node B (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home evolved node B, or some other suitable term.

[0048] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, and other examples. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, and other examples, which may be implemented in various articles such as electrical appliances, vehicles, meters, and other examples.

[0049] The UE 115 described in this document can communicate with various types of devices, such as other UE 115s that can sometimes act as repeaters, as well as base station 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, and other examples, such as... Figure 1 As shown.

[0050] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0051] In some examples (e.g., in a carrier aggregation configuration), carriers may also have acquisition or control signaling that coordinates operation against other carriers. Carriers may be associated with frequency channels (e.g., Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be positioned according to a channel grid for discovery by UE 115. Carriers may operate in standalone mode, where UE 115 performs initial acquisition and connection via a carrier, or in non-standalone mode, where different carriers (e.g., the same or different radio access technologies) are used to anchor the connection.

[0052] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The carrier may carry downlink or uplink communication (e.g., in FDD mode) or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0053] A carrier can be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth can be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth can be one of a number of defined bandwidths for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) can have a hardware configuration that supports communication on a specific carrier bandwidth, or can be configured to support communication on one carrier bandwidth in a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 can be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0054] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as Orthogonal Frequency Division Multiplexing (OFDM) or Discrete Fourier Transform Spread Spectrum OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements UE 115 receives and the higher the order of the modulation scheme, the higher the data rate can be for UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity used for communication with UE 115.

[0055] One or more digital schemes (numerologies) can be supported for a carrier, where the digital scheme may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier can be divided into one or more BWPs with the same or different digital schemes. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and communication for UE 115 can be restricted to one or more active BWPs.

[0056] It can be expressed in a basic unit of time (which can be, for example, T). s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N f The time interval for base station 105 or UE 115 can be represented as a multiple of the maximum supported Discrete Fourier Transform (DFT) size. The time interval for communication resources can be organized based on radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0057] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., this depends on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N) f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0058] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst form of a shortened TTI (sTTI)).

[0059] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by the number of symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a group of UEs 115. For example, one or more of the UEs 115 can monitor or search for control regions against control information based on one or more search space sets, and each search space set can include one or more control channel candidates arranged in a cascaded manner at one or more aggregation levels. The aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set used to send control information to a specific UE 115.

[0060] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used (e.g., on a carrier) to communicate with base station 105 and may be associated with an identifier used to distinguish neighboring cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or other identifier). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors (such as the capabilities of base station 105), the range of such cells can range from small areas (e.g., structures, subsets of structures) to large areas. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, and other examples.

[0061] Macro cells typically cover a relatively large geographical area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 115 with a service subscription to a network provider supporting the macro cell. In contrast, small cells can be associated with a lower-power base station 105 and can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UE 115 with a service subscription to a network provider, or restricted access to UE 115 associated with the small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a residence or office). Base station 105 can support one or more cells and can also support communication on one or more cells using one or more component carriers.

[0062] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0063] In some examples, base station 105 may be mobile, and therefore provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0064] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timings, and transmissions from different base stations 105 can be approximately time-aligned. For asynchronous operation, base stations 105 can have different frame timings, and in some examples, transmissions from different base stations 105 may not be time-aligned. The techniques described herein can be used for both synchronous and asynchronous operation.

[0065] Some UE 115s (e.g., MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated machine-to-machine communication (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices that have integrated sensors or meters to measure or capture information and relay such information to a central server or application that uses the information or presents it to humans interacting with the application. Some UE 115s can be designed to collect information or automate the behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based billing.

[0066] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via either transmission or reception, rather than simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power-saving techniques for UE 115 include entering a power-saving deep sleep mode when not engaged in active communication, when operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs) within a carrier, within a carrier's guard band, or outside a carrier.

[0067] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can 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 can include service prioritization, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0068] In some examples, UE 115 is able to communicate directly with other UE 115 on a device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, groups of UE 115s communicating via D2D communication can utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.

[0069] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicle may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. The vehicle may signal information relating to traffic conditions, signal control, weather, safety, emergencies, or any other information relating to the V2X system. In some examples, a vehicle in a V2X system may communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or both.

[0070] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function unit (AMF)) managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function unit (UPF)) routing packets to or interconnecting with external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to network operator IP service 150. Carrier IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0071] Some network devices (e.g., base station 105) may include sub-components such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transport entities 145 (which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP)). 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 individual network devices (e.g., radio headends and ANCs) or incorporated into a single network device (e.g., base station 105).

[0072] Wireless communication system 100 can operate using one or more frequency bands (typically in the range of 300 MHz to 300 GHz). The region from 300 MHz to 3 GHz is often referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves can be sufficiently permeable to penetrate structures for use in macrocells to provide service to UE 115 located indoors. Compared to the transmission of smaller frequencies and longer waves in the lower 300 MHz portion of the spectrum in the High Frequency (HF) or Very High Frequency (VHF) regions, UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0073] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also referred to as the centimeter band) or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding device can be even smaller and more closely spaced compared to UHF antennas. In some examples, this can facilitate the use of antenna arrays within the device. However, EHF transmissions may suffer from even greater atmospheric attenuation and shorter distances compared to SHF or UHF transmissions. The techniques disclosed herein can be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary depending on the country or regulatory authority.

[0074] Wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio frequency spectrum bands, devices (such as base station 105 and UE 115) can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands can be based on carrier aggregation configurations that combine component carriers operating in licensed frequency bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and other examples.

[0075] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operation or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array having a number of rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.

[0076] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such a technique can be called spatial multiplexing. For example, a transmitting device can transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device can receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) (where multiple spatial layers are transmitted to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are transmitted to multiple devices).

[0077] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to form or guide an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating relative to a specific orientation of the antenna array experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with the transmitting or receiving device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).

[0078] As part of beamforming operations, base station 105 or UE 115 may use beam scanning techniques. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Base station 105 may transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device (such as base station 105) or by a receiving device (such as UE 115)) to identify the beam direction for subsequent transmissions or receptions performed by base station 105.

[0079] Base station 105 may transmit signals (e.g., data signals associated with a specific receiving device, such as UE 115) in a single beam direction (e.g., a direction associated with a particular receiving device, such as UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 that has the highest signal quality or otherwise acceptable signal quality.

[0080] In some examples, multiple beam directions can be used to perform transmissions by a device (e.g., base station 105 or UE 115), and the device can use a combination of digital precoding or radio frequency beamforming to generate combined beams for (e.g., from base station 105 to UE 115) transmissions. UE 115 can report feedback indicating precoding weights for one or more beam directions, and this feedback can correspond to a configured number of beams spanning the system bandwidth or one or more subbands. Base station 105 can transmit reference signals that can be precoded or unprecoded (e.g., cell-specific reference signals (CRS), CSI reference signals (CSI-RS)). UE 115 can provide feedback on beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify beam directions for subsequent transmissions or receptions by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0081] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, the receiving device (e.g., UE 115) can attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device can attempt multiple receiving directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or by processing the received signals according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (any of these operations can be referred to as "listening" according to different receiving configurations or receiving directions). In some examples, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). A single receiver configuration can be aligned to a beam direction determined based on listening in different receiver configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening in multiple beam directions).

[0082] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet fragmentation and reassembly for transmission over logical channels. The Media Access Control (MAC) layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide the establishment, configuration, and maintenance of RRC connections (which support radio bearers for user plane data) between the UE 115 and the base station 105 or core network 130. At the physical layer, transport channels can be mapped to physical channels.

[0083] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correct data reception on communication link 125. HARQ can include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal and noise conditions). In some examples, the device can support same-slot HARQ feedback, where the device can provide HARQ feedback for data received in a previous symbol within a specific time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0084] In some examples, UE 115 may receive one or more DCI messages from base station 105 via one or more component carriers or serving cells. For example, UE 115 may receive DCIs associated with uplink shared channel (e.g., PUSCH) transmissions and DCIs associated with downlink shared channel (e.g., PDSCH) transmissions. UE 115 may attempt to transmit UCIs (e.g., feedback messages, scheduling requests, CSI reports, etc. in response to PDSCH transmissions) on uplink control channels (e.g., PUCCH) and uplink signals (e.g., including control information or data) on PUSCH. In some cases, when resources associated with PUCCH (e.g., time-frequency resources) and resources associated with PUSCH overlap, UE 115 may multiplex at least a portion of the UCIs and uplink signals on PUSCH. In some cases, UE 115 may multiplex feedback information from UCIs (e.g., HARQ acknowledgments (ACKs)) in PUSCH transmissions. Alternatively, UE 115 can multiplex CSI reports during PUSCH transmission.

[0085] In some other cases, the resources associated with the PUCCH may not overlap with those associated with the PUSCH. The UE 115 can multiplex feedback information (e.g., with or without a scheduling request) and one or more CSI reports in the same PUCCH based on configuration instructions from the base station 105. Therefore, when the resources associated with the PUCCH overlap with those associated with the PUSCH, the UE 115 can multiplex the UCI associated with the PUCCH in the PUSCH; or, if the resources associated with the PUCCH and those associated with the PUSCH do not overlap, the UE 115 can multiplex the UCI in the same PUCCH. However, the UE 115's ability to multiplex UCI in the PUSCH may be limited. For example, the UE 115 can multiplex acknowledgment feedback information, CSI, or both in the PUSCH and can discard the PUCCH, including any other UCI that may have already been transmitted on the PUCCH, which could lead to inefficient communication (e.g., due to UCI retransmissions).

[0086] The wireless communication system 100 may support techniques that enable the UE 115 to determine a UCI transmission mode that supports transmission of UCI on the PUCCH and uplink signals on the PUSCH (when the resources of the PUCCH and the PUSCH at least partially overlap), which can improve reliability (e.g., coverage) at the UE 115. In some cases, the UE 115 can execute one or more UCI transmission modes. For example, in a UCI transmission mode, the UE 115 can transmit UCI on a PUCCH with resources (e.g., time-frequency resources) that overlap with the PUSCH. In another UCI transmission mode, the UE 115 can multiplex UCI in the PUSCH, and in some cases, can discard the PUCCH.

[0087] In some cases, UE 115 can send a capability indication to base station 105. In some examples, base station 105 can send a configuration to UE 115 indicating the use of the UCI transmission mode. UE 115 can transmit UCI on the PUCCH and uplink signaling on the PUSCH based on the configuration from base station 105. In some cases, base station 105 can send the configuration to UE 115 via RRC signaling. In some examples, if the serving cell of the PUCCH is not configured with a TCI state (e.g., the PUCCH may lack beam configuration), UE 115 can receive the RRC configuration from base station 105. In some cases, the PUCCH and PUSCH can be associated with the same serving cell. In other cases, the PUCCH and PUSCH can be associated with different serving cells.

[0088] Figure 2 Examples of a wireless communication system 200 supporting UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmission according to various aspects of this disclosure are shown. In some examples, the wireless communication system 200 may implement various aspects of the wireless communication system 100 and may include a UE 115-a, a base station 105-a having a coverage area 110-a, and a communication link 125-a, which may be referenced to Figure 1 Examples of UE 115, base station 105, and communication link 125 are described herein. As described herein, UE 115 can determine the capability associated with transmission from UCI 205 to base station 105, which can improve reliability at UE 115 (e.g., due to increased frequency-related coverage and reduced CSI report drops).

[0089] In some examples, UE 115 may receive one or more DCI messages from base station 105 via one or more component carriers or serving cells. For example, UE 115-a may receive DCI messages associated with uplink shared channel transmissions and DCI messages associated with downlink shared channel (e.g., PDSCH) transmissions. DCI messages may be associated with different cells or the same cell. UE 115 may attempt to transmit UCI 205 (e.g., feedback messages, scheduling requests, CSI reports, etc. in response to PDSCH transmissions) on an uplink control channel (e.g., PUCCH 210) and uplink signal 215 (e.g., including control information or data) on an uplink shared channel (e.g., PUSCH 220) based on one of the one or more DCI messages. In some cases, due to the minimum processing time associated with PUCCH and PUSCH transmissions, UE 115 may multiplex at least a portion of UCI 205 and uplink signal 215 on the uplink channel (e.g., PUSCH 220).

[0090] In some cases, UE 115 may multiplex UCI 205 when resources associated with an uplink control channel (e.g., PUCCH 210) (e.g., time-frequency resources) overlap with resources associated with an uplink shared channel (e.g., PUSCH 220). For example, UE 115 may multiplex UCI 205 in a PUCCH transmission that overlaps with a PUSCH transmission. In some cases, UE 115 may multiplex feedback information (e.g., HARQ ACK) from UCI 205 in a PUSCH transmission. Alternatively, UE 115 may multiplex CSI reports in a PUSCH transmission. In some cases, CSI reports may be periodic, non-periodic, or semi-persistent. In some cases, for example, if UE 115 multiplexes UCI 205 in a PUSCH transmission, UE 115 may not transmit on PUCCH 210. If feedback information and one or more CSI reports are multiplexed in the PUSCCH transmission, UE115 may not send a scheduling request.

[0091] In some other cases, the resources associated with PUCCH 210 may not overlap with those associated with PUSCH 220. UE 115 may multiplex feedback information (e.g., with or without a scheduling request) and one or more CSI reports within the same PUCCH 210 based on configuration indications (e.g., simultaneous HARQ ACK-CSI). In some examples, UE 115 may be configured to use one or more PUCCH resources in a time slot, or may determine to use one or more PUCCH resources in a time slot to transmit one or more CSI reports. For example, base station 105 may not provide UE 115 with a multi-CSI report configuration indication (e.g., multi-CSI-PUCCH-ResourceList), or the PUCCH resources used for CSI report transmission may not overlap in time slots, so UE 115 may use the resources corresponding to the CSI report with the highest priority relative to other CSI reports among the one or more CSI reports. In some other examples, base station 105 may provide UE 115 with a multi-CSI report configuration indication, or the PUCCH resources used for CSI report transmission may overlap in time slots, and UE 115 may multiplex one or more CSI reports in the resources provided by the indication. In some cases, UE 115 may not send more than one PUCCH 210 with feedback information per time slot.

[0092] Therefore, when the resources associated with PUCCH 210 overlap with those associated with PUSCH 220, UE 115 can multiplex the UCI 205 associated with PUCCH 210 within PUSCH 210. Alternatively, if the resources associated with PUCCH 210 and PUSCH 220 do not overlap, UE 115 can multiplex the UCI 205 within the same PUCCH 210. However, UE 115's ability to multiplex UCI 205 within PUSCH 220 may be limited. For example, UE 115 can multiplex acknowledgment feedback, CSI, or both within PUSCH 220 and can discard PUCCH 210, including any other UCI 205 that may have already been transmitted on PUCCH 210, which could lead to inefficient communication (e.g., due to retransmissions of UCI 205).

[0093] The wireless communication system 200 may support a technique that enables UE 115 to determine the ability to support a UCI transmission mode corresponding to transmitting UCI 205 on PUCCH 210 and uplink signal 215 on PUSCH 220 (when the resources of PUCCH 210 and PUSCH 220 overlap at least partially in time), which can improve reliability (e.g., coverage) at UE 115. In some cases, UE 115-a can execute one or more UCI transmission modes. For example, in a UCI transmission mode, UE 115-a can utilize resources overlapping with PUSCH 220 (e.g., time-frequency resources) to transmit UCI 205 on PUCCH 210, and can also transmit overlapping PUSCH 220. In another UCI transmission mode, UE 115-a can multiplex UCI 205 in PUSCH 220, and in some cases, can discard PUCCH 210.

[0094] In some cases, UE 115-a may send an indication of capability 225 to base station 105-a via communication link 125-a. For example, UE 115-a may send capability 225 as a parameter (e.g., sim-PUCCH-PUSCH-UL) in a UE capability report. This parameter may be included as a bit in the UE capability report or may be reported together with another UE capability. In some examples, base station 105-a may send configuration 230 to UE 115-a via communication link 125-a to indicate the use of a UCI transmission mode. For example, UE 115-a may send UCI 205 on PUCCH 210 and uplink signal 215 on PUSCH 220 based on configuration 230 of the UCI transmission mode from base station 105-a. In some cases, base station 105-a may send configuration 230 to UE 115-a via RRC signaling. Alternatively, base station 105-a may send configuration 230 to UE 115-a via MAC control element (MAC-CE) or DCI. Base station 105-a may include parameters (e.g., sim-PUCCH-PUSCH) in RRC signaling and may enable the transmission mode at UE 115-a based on adjusting these parameters. That is, if the configuration is set to enabled, UE 115-a may concurrently transmit UCI 205 on PUCCH 220 and uplink signal 215 on PUSCH 220 when PUCCH 210 and PUSCH 220 overlap at least partially in time. However, if the configuration is disabled, or base station 105-a does not configure RRC parameters, UE 115-a may multiplex UCI 205 in PUSCH 220 and, in some cases, may discard PUCCH 210. In some examples, if the serving cell of PUCCH 210 is not configured with a TCI state (for example, PUCCH 220 may lack a beam configuration), UE 115-a can receive RRC configuration from base station 105-a.

[0095] In some cases, PUCCH 210 and PUSCH 220 can be associated with the same serving cell, which will be related to... Figure 3 Further details. In some other cases, PUCCH 210 and PUSCH 220 can be associated with different serving cells, which will relate to... Figure 4Further details are provided. In some cases, the serving cell of PUCCH 210 may be associated with frequency range 1 (FR1), and the serving cell of PUSCH 220 may be associated with frequency range 2 (FR2). In some examples, transmissions on FR1 may have improved coverage and reliability compared to transmissions on FR2 (e.g., because FR1 may have better coverage and be more robust than FR2). For example, transmitting UCI 205 on PUCCH 210 instead of on PUSCH 220 can improve signaling reliability at UE 115-a. Alternatively, when a periodic or semi-periodic CSI report is triggered on PUCCH 210 for a serving cell (e.g., the serving cell associated with PUCCH 210) and an aperiodic CSI report is triggered on PUSCH 220 for another serving cell (e.g., the serving cell associated with PUSCH 220), sending UCI 205 on PUCCH 210 instead of on PUSCH 220 avoids dropping CSI reports on PUCCH 210. Therefore, sending UCI 205 on PUCCH 210 can improve signaling overhead (e.g., due to fewer retransmissions of CSI reports).

[0096] Figure 3 An example of a processing timeline 300 supporting UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmission, according to various aspects of this disclosure, is shown. In some examples, the processing timeline 300 may implement aspects of wireless communication system 100, wireless communication system 200, or both, and may include PUCCH 210-a, PUSCH 220-a, and PUSCH 220-b, which may be referenced... Figure 2 Examples of the PUCCH 210 and PUSCH 220 are described. See reference [reference]. Figure 1 and 2 The process described is implemented at UE 115 or base station 105 as shown in processing timeline 300. For example, processing timeline 300 may show a method by which UE 115 may transmit one or more uplink transmissions during PUCCH 210, PUSCH 220, or both. In some cases, processing timeline 300 may be associated with a single serving cell 305-a (e.g., a single component carrier).

[0097] In some examples, UE 115 may receive one or more messages, including DCI 310, from base station 105 via one or more component carriers or serving cells, as shown in reference 115. Figure 2Described. For example, UE 115 may receive DCI 310-a to DCI 310-d, which may be associated with cell 305-a. In some examples, DCI 310-a and DCI 310-c may be associated with transmissions on downlink shared channels (e.g., PDSCH 315-a and PDSCH 325-b, respectively). UE 115 may send a feedback message, such as ACK or NACK, to base station 105 in response to receiving PDSCH 315. UE 115 may present the feedback message as UCI 205 in an uplink control channel (e.g., PUCCH 210-a), which may be as referenced. Figure 2 The UE 115 may transmit as part of an example of UCI 205 (described below). In some cases, the UE 115 may also transmit a CSI report, a scheduling request, or both as part of UCI 205 in PUCCH 210-a. In some cases, DCI 310-b and DCI 310-d may be associated with uplink signals (e.g., control information or data) to be transmitted in PUSCH 220-a and PUSCH 220-b, respectively. The UE 115 may wait for processing time after receiving PDSCH 310-a and DCI 310-b. However, in some cases, the resources associated with PUCCH 210-a and PUSCH 220-a may overlap. For example, PUCCH 210-a and PUSCH 220-a may overlap in time, which may cause the UE 115 to fail to meet the timing conditions associated with uplink transmissions.

[0098] In some cases, UE 115 can multiplex UCI 205, such as feedback information and CSI reports, on PUSCH 220-b based on the determination that PUCCH 210 and PUSCH 220-b overlap in time. In some cases, UE 115 can discard scheduling requests associated with UCI 205 based on the overlapping PUSCH 220-b. In some examples, if PUSCH 220-b does not have aperiodic or semi-persistent CSI reports, UE 115 can multiplex CSI reports from UCI 205 associated with PUCCH 210 on PUSCH 220-b. Otherwise, if PUSCH 220-b has aperiodic or semi-persistent CSI reports, UE 115 may discard one or more CSI reports from UCI 205 associated with PUCCH 210 and may multiplex feedback information from UCI 205 associated with PUSCH 210 on PUSCH 220-b. The UE may not expect to multiplex UCI 205 in a single time slot with a subcarrier spacing configuration of the same type as the PUCCH that UE 115 will transmit in different time slots with different subcarrier spacings. In some cases, if resources do not overlap on the same cell 305, UE 115 may transmit both PUCCH 210 and PUSCH 220, which can improve latency associated with processing time, as per [reference to...]. Figure 4 Further detailed description.

[0099] Figure 4 An example of a processing timeline 400 supporting UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmission, according to various aspects of this disclosure, is shown. In some examples, processing timeline 400 may implement aspects of wireless communication system 100, wireless communication system 200, or both, and processing timeline 300. Processing timeline 400 may include PUCCH 210-b, PUCCH 210-c, PUSCH 220-c, PUSH 220-d, which may be referenced... Figure 2 Examples of the PUCCH 210 and PUSCH 220 are described. See reference [reference]. Figure 1 and 2 The process described is implemented at UE 115 or base station 105 as shown in processing timeline 400. For example, processing timeline 400 may show a method by which UE 115 may transmit one or more uplink transmissions during PUCCH 210, PUSCH 220, or both. In some cases, processing timeline 300 may be associated with multiple serving cells (e.g., serving cell 405-a and serving cell 405-b).

[0100] In some examples, UE 115 may receive one or more messages, including DCI 410, from base station 105 via one or more component carriers or serving cells, as shown in reference 115. Figure 2 and 3 Described. For example, UE 115 can receive DCI 410-a to DCI 410-d from base station 105. In some cases, DCI 410-a and DCI 410-c may be associated with cell 405-a, and DCI 410-b and DCI 410-d may be associated with cell 405-b. In some examples, DCI 410-a and DCI 410-c may be associated with transmissions on downlink shared channels (e.g., PDSCH 415-a and PDSCH 415-b, respectively). UE 115 may send a feedback message, such as ACK or NACK, to base station 105 in response to receiving PDSCH 415. UE 115 may send the feedback message as UCI 205 (which may be a reference) in an uplink control channel (e.g., PUCCH 210). Figure 2 The UE 115 may transmit as part of the example of UCI 205 described. In some cases, the UE 115 may also transmit CSI reports, scheduling requests, or both as part of UCI 205 in PUCCH 210. In some cases, DCI 410-b and DCI 410-d may be associated with uplink signals (e.g., control information or data) to be transmitted in PUSCH 220-c and PUSCH 220-d, respectively.

[0101] UE 115 may wait for processing time after receiving PDSCH 415-a and DCI 410-b. In some cases, resources associated with PUCCH 210-b may overlap in time with resources associated with PUSCH 220-c on another serving cell. For example, resources associated with PUCCH 210-b and PUCCH 210-c corresponding to cell 405-a may overlap in time with resources associated with PUSCH 220-c and PUSCH 220-d corresponding to cell 405-b. In some cases, UE 115 may transmit UCI (e.g., including feedback information such as HARQACK, one or more CSI reports, scheduling requests, or combinations thereof) on PUCCH 210-b or PUCCH 210-c, and may transmit uplink signaling on PUSCH 220-c or PUSCH 220-d. In some cases, such as if PUCCH 210 overlaps in time with another PUSCH transmission, UE 115 can avoid sending a scheduling request. That is, if a transmission on PUSCH 220-d overlaps in time with PUCCH 210-c, UE 115 can concurrently send PUSCH 220-d and PUCCH 210-c. In some examples, UE 115 may not send a scheduling request on PUCCH 210-c. In some cases, UE 115 may send aperiodic or semi-persistent CSI reports on PUCCH 210-c, regardless of whether PUSCH 220-d has aperiodic or semi-persistent CSI reports.

[0102] Figure 5 Examples of process flow 500 supporting UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmissions according to various aspects of this disclosure are shown. In some examples, process flow 500 may implement various aspects of wireless communication systems 100 and 200. Process flow 500 may illustrate an example of UE 115 (such as UE 115-b) determining its ability to execute a UCI transmission mode and, based on that ability, sending uplink transmissions to base station 105 (such as base station 105-b). Alternative examples may be implemented, some of which may be performed in a different order than described or not performed at all. In some cases, the process may include additional features not mentioned below, or additional processes may be added.

[0103] At 505, UE 115-b can determine its ability to perform at least a first mode and a second mode of UCI transmission. In some cases, the first mode may correspond to concurrently transmitting UCI on an uplink control channel (e.g., PUCCH) and uplink signaling on an uplink shared channel (e.g., PUSCH), such that the PUCCH and PUSCH at least partially overlap in time. In some examples, when the PUCCH and PUSCH at least partially overlap in time, the second mode may correspond to transmitting UCI from the PUCCH and uplink signaling on the PUSCH. In some cases, UCI may include feedback information (e.g., HARQ ACK), CSI reports (e.g., periodic CSI reports, aperiodic CSI reports, or semi-persistent CSI reports), scheduling requests, or combinations thereof.

[0104] At 510, UE 115-b can determine that the PUCCH and PUSCH are configured on the same serving cell. In some cases, UE 115-b can determine capability at 505 based on the PUCCH and PUSCH being on the same serving cell. In some cases, UE 115-b can determine that the PUCCH at least partially overlaps with the PUSCH during a time period, where the PUCCH and PUSCH are located on the same serving cell. In some examples, UE 115-b can discard a scheduling request based on the overlap of the PUCCH with the PUSCH during that time period. Alternatively or additionally, UE 115-b can determine the type of CSI report (e.g., aperiodic CSI report or semi-persistent CSI) that is absent on the PUSCH during that time period. UE 115-b can reuse a CSI report (e.g., another type of CSI report, such as aperiodic CSI report) based on this absence.

[0105] At 515, UE 115-b can determine that the PUCCH and PUSCH are configured on different serving cells (e.g., a first serving cell and a second serving cell different from the first serving cell). In some cases, UE 115-b can determine capabilities at 505 based on the PUCCH and PUSCH on different serving cells. In some cases, UE 115-b can determine that the PUCCH and PUSCH do not overlap in time during a certain period. UE 115-b can send a scheduling request based on the non-overlapping of PUCCH and PUSCH during that time period.

[0106] At point 520, UE 115-b can send an indication of the determined capabilities to base station 105-b. At point 525, base station 105-b can determine the capability of UE 115-b to perform at least a first mode of UCI transmission and a second mode of UCI transmission.

[0107] At position 530, base station 105-b can send a configuration to UE 115-b instructing UE 115-b to use the first mode of UCI transmission. In some cases, UE 115-b can receive the configuration based on a PUCCH lacking beam configuration (i.e., TCI state). For example, a serving cell with a PUCCH can be configured on FR1. In some cases, base station 105-b can send this configuration via RRC signaling, MAC-CE, or DCI.

[0108] At 535, UE 115-b can transmit UCI on the PUCCH and uplink signals on the PUSCH based on receiving this configuration. In some examples, the uplink signals may include control information, data, or both.

[0109] Figure 6 A block diagram 600 of a device 605 supporting UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmissions according to various aspects of this disclosure is shown. Device 605 may be an example of various aspects of UE 115 as described herein. Device 605 may include a receiver 610, a communication manager 615, and a transmitter 620. Device 605 may also include one or more processors, memory coupled to the one or more processors, and instructions stored in the memory that can be executed by the one or more processors to enable the one or more processors to perform the UCI multiplexing rule uplink transmission features discussed herein. Each of these components may communicate with each other (e.g., via one or more buses).

[0110] Receiver 610 can receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmission). This information can be passed to other components of device 605. Receiver 610 can be a reference... Figure 9 Examples of various aspects of the transceiver 920 are described. The receiver 610 can utilize a single antenna or a set of antennas.

[0111] The communication manager 615 can perform the following operations: determine the UE's capability to perform at least a first mode of UCI transmission and a second mode of UCI transmission, the first mode corresponding to UCI transmission on an uplink control channel that at least partially overlaps in time with the uplink shared channel, and the second mode corresponding to UCI transmission multiplexed on the uplink shared channel; receive from the base station a configuration indicating that the UE will use the first mode of UCI transmission; and based on the received configuration, transmit UCI on the uplink control channel and transmit uplink signals on the uplink shared channel. The communication manager 615 can be an example of various aspects of the communication manager 910 described herein.

[0112] The operations performed by the communication manager 615 as described herein can be implemented to achieve one or more potential advantages. One implementation enables the UE to determine its capability to transmit UCI on the PUCCH and uplink signaling on the PUSCH. The UE can transmit UCI on the PUCCH, which can result in improved signaling reliability at the UE (e.g., better coverage), as well as other advantages.

[0113] By implementing the UCI transmission capabilities described herein, the processor of the UE or base station (e.g., a processor controlling receiver 610, communication manager 615, transmitter 620, or a combination thereof) can reduce the impact or likelihood of unnecessary monitoring while ensuring relatively efficient communication. For example, capability-based UCI transmission as described herein can utilize PUCCH and PUSCH, which overlap at least partially in time, to transmit UCI and uplink signals respectively, which can achieve reduced signaling overhead (e.g., due to fewer dropped CSI reports) and other benefits.

[0114] The communication manager 615 or its sub-components may be implemented in hardware, processor-executable code (e.g., software or firmware), or any combination thereof. If implemented in processor-executable code, the functionality of the communication manager 615 or its sub-components may be performed by a general-purpose processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described in this disclosure.

[0115] The communication manager 615 or its subcomponents may be physically located at various locations, including being distributed such that some functions are implemented by one or more physical components at different physical locations. In some examples, according to various aspects of this disclosure, the communication manager 615 or its subcomponents may be separate and distinct components. In some examples, according to various aspects of this disclosure, the communication manager 615 or its subcomponents may be combined with one or more other hardware components, including but not limited to input / output (I / O) components, transceivers, network servers, other computing devices, one or more other components described in this disclosure, or combinations thereof.

[0116] Transmitter 620 can transmit signals generated by other components of device 605. In some examples, transmitter 620 can be co-located with receiver 610 in a transceiver module. For example, transmitter 620 can be a reference... Figure 9 Examples of various aspects of the transceiver 920 are described. The transmitter 620 can utilize a single antenna or a set of antennas.

[0117] Figure 7 A block diagram 700 of a device 705 supporting UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmissions according to various aspects of this disclosure is shown. Device 705 may be an example of aspects of device 605 or UE 115 as described herein. Device 705 may include a receiver 710, a communication manager 715, and a transmitter 735. Device 705 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0118] Receiver 710 can receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmission). This information can be passed to other components of device 705. Receiver 710 can be a reference... Figure 9 Examples of various aspects of the transceiver 920 are described. The receiver 710 can utilize a single antenna or a set of antennas.

[0119] Communication manager 715 may be an example of aspects of communication manager 615 as described herein. Communication manager 715 may include capability component 720, configuration component 725, and uplink transmission component 730. Communication manager 715 may be an example of aspects of communication manager 910 as described herein.

[0120] Capability component 720 can determine the UE's capability to perform at least a first mode of UCI transmission and a second mode of UCI transmission, the first mode corresponding to UCI transmission on an uplink control channel that at least partially overlaps in time with the uplink shared channel, and the second mode corresponding to UCI transmission multiplexed on the uplink shared channel. Configuration component 725 can receive from the base station a configuration indicating that the UE will use the first mode of UCI transmission. Uplink transmission component 730 can transmit UCI on the uplink control channel and uplink signals on the uplink shared channel based on the received configuration.

[0121] Transmitter 735 can transmit signals generated by other components of device 705. In some examples, transmitter 735 can be co-located with receiver 710 in a transceiver module. For example, transmitter 735 can be a reference... Figure 9 Examples of various aspects of the transceiver 920 are described. The transmitter 735 can utilize a single antenna or a set of antennas.

[0122] In some cases, capability component 720, configuration component 725, and uplink transmission component 730 may each be a processor (e.g., a transceiver processor, a radio processor, a transmitter processor, or a receiver processor) or at least a part thereof. The processor may be coupled to memory and execute instructions stored in the memory that enable the processor to perform or facilitate the features of capability component 720, configuration component 725, and uplink transmission component 730 discussed herein. The transceiver processor may co-locate and / or communicate (e.g., instruct its operation) with the transceiver of the device. The radio processor may co-locate and / or communicate (e.g., instruct its operation) with the radio of the device (e.g., NR radio, LTE radio, Wi-Fi radio). The transmitter processor may co-locate and / or communicate (e.g., instruct its operation) with the transmitter of the device. The receiver processor may co-locate and / or communicate (e.g., instruct its operation) with the receiver of the device.

[0123] Figure 8 A block diagram 800 of a communication manager 805 supporting UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmissions, according to various aspects of this disclosure, is shown. The communication manager 805 may be an example of aspects of the communication manager 615, communication manager 715, or communication manager 910 described herein. The communication manager 805 may include a capability component 810, a configuration component 815, an uplink transmission component 820, a resource component 825, and a CSI component 830. Each of these modules may communicate directly or indirectly with each other (e.g., via one or more buses).

[0124] Capability component 810 can determine the UE's capability to perform at least a first mode of UCI transmission and a second mode of UCI transmission, the first mode corresponding to UCI transmission on an uplink control channel that at least partially overlaps in time with the uplink shared channel, and the second mode corresponding to UCI transmission multiplexed on the uplink shared channel. In some examples, capability component 810 can send an indication of the determined capability to the base station.

[0125] In some examples, capability component 810 can determine that the uplink control channel and the uplink shared channel are configured on the same serving cell, wherein the UE's capability is determined based on the uplink control channel and the uplink shared channel being configured on the same serving cell. In some examples, capability component 810 can determine that the uplink control channel is configured on a first serving cell and the uplink shared channel is configured on a second serving cell different from the first serving cell, wherein the UE's capability is determined based on the uplink control channel being configured on a different serving cell than the uplink shared channel.

[0126] Configuration component 815 can receive configuration from the base station indicating that the UE will use a first mode for UCI transmission. In some cases, configuration component 815 may receive configuration based on a lack of beam configuration on the uplink control channel. In some examples, configuration component 815 may receive configuration via RRC signaling. Uplink transmission component 820 may transmit UCI on the uplink control channel and uplink signals on the uplink shared channel based on the received configuration.

[0127] Resource component 825 can determine that the uplink control channel and the uplink shared channel overlap at least partially in time during a time period, wherein the uplink control channel and the uplink shared channel are configured on the same serving cell. In some examples, resource component 825 can discard scheduling requests based on the overlap between the uplink control channel and the uplink shared channel during a time period.

[0128] CSI component 830 can determine that no second type of CSI report exists during the specified time period. In some examples, CSI component 830 can reuse a first type of CSI report based on the absence of a second type of CSI report. In some cases, the first type of CSI report is periodic, and the second type of CSI report is non-periodic or semi-persistent.

[0129] In some examples, resource component 825 can determine that the uplink control channel does not overlap with the uplink shared channel in time during a time period. In some examples, resource component 825 can send a scheduling request to the base station based on the fact that the uplink control channel does not overlap with the uplink shared channel in time during that time period.

[0130] In some cases, capability component 810, configuration component 815, uplink transmission component 820, resource component 825, and CSI component 830 may each be a processor (e.g., a transceiver processor, a radio processor, a transmitter processor, or a receiver processor) or at least a part thereof. The processor may be coupled to memory and execute instructions stored in memory that enable the processor to perform or facilitate the features of capability component 810, configuration component 815, uplink transmission component 820, resource component 825, and CSI component 830 discussed herein.

[0131] Figure 9 A diagram of a system 900 including device 905 supporting UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmissions, according to various aspects of this disclosure, is shown. Device 905 may be an example of device 605, device 705, or UE 115 as described herein, or a component including device 605, device 705, or UE 115. Device 905 may include components for bidirectional voice and data communication, including components for transmitting and receiving communications, including a communication manager 910, I / O controller 915, transceiver 920, antenna 925, memory 930, and processor 940. These components may communicate electronically via one or more buses (e.g., bus 945).

[0132] The communication manager 910 can perform the following operations: determine the UE's ability to perform at least a first mode of UCI transmission and a second mode of UCI transmission, the first mode corresponding to UCI transmission on an uplink control channel that overlaps at least partially in time with the uplink shared channel, and the second mode corresponding to UCI transmission multiplexed on the uplink shared channel; receive from the base station a configuration indicating that the UE will use the first mode of UCI transmission; and based on the received configuration, transmit UCI on the uplink control channel and transmit uplink signals on the uplink shared channel.

[0133] The I / O controller 915 can manage input and output signals for device 905. The I / O controller 915 can also manage peripheral devices not integrated into device 905. In some cases, the I / O controller 915 can represent a physical connection or port to an external peripheral device. In some cases, the I / O controller 915 can utilize, for example... This can be an operating system such as a modem, keyboard, mouse, touchscreen, or similar device, or an interface with such devices. In some cases, the I / O controller 915 may be implemented as part of a processor. In some cases, a user may interact with the device 905 via the I / O controller 915 or via hardware components controlled by the I / O controller 915.

[0134] Transceiver 920 can communicate bidirectionally via one or more antennas, wired or wireless links as described above. For example, transceiver 920 can represent a wireless transceiver and can communicate bidirectionally with another wireless transceiver. Transceiver 920 may also include a modem for modulating packets and providing the modulated packets to the antenna for transmission, and for demodulating packets received from the antenna.

[0135] In some cases, a wireless device may include a single antenna 925. However, in other cases, the device may have more than one antenna 925, which are capable of transmitting or receiving multiple wireless transmissions simultaneously.

[0136] Memory 930 may include random access memory (RAM) and read-only memory (ROM). Memory 930 may store computer-readable, computer-executable code 935, which includes instructions that, when executed, cause the processor to perform the various functions described herein. In some cases, in addition to this, memory 930 may also contain a basic I / O system (BIOS) that controls basic hardware or software operations, such as interaction with peripheral components or devices.

[0137] Processor 940 may include intelligent hardware devices (e.g., general-purpose processors, DSPs, central processing units (CPUs), microcontrollers, ASICs, FPGAs, programmable logic devices, discrete gate or transistor logic components, discrete hardware components, or any combination thereof). In some cases, processor 940 may be configured to use a memory controller to operate a memory array. In other cases, the memory controller may be integrated into processor 940. Processor 940 may be configured to execute computer-readable instructions stored in memory (e.g., memory 930) to cause device 905 to perform various functions (e.g., functions or tasks supporting UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmissions).

[0138] Code 935 may include instructions for implementing various aspects of this disclosure, including instructions for supporting wireless communication. Code 935 may be stored in a non-transitory computer-readable medium (e.g., system memory or other types of memory). In some cases, code 935 may not be directly executable by processor 940, but may cause a computer (e.g., when compiled and executed) to perform the functions described herein.

[0139] Figure 10 A block diagram 1000 of a device 1005 supporting UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmissions, according to various aspects of this disclosure, is shown. Device 1005 may be an example of various aspects of base station 105 as described herein. Device 1005 may include a receiver 1010, a communication manager 1015, and a transmitter 1020. Device 1005 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0140] Receiver 1010 can receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to UCI multiplexing rules for simultaneous uplink control channel and uplink shared channel transmission). This information can be passed to other components of device 1005. Receiver 1010 can be a reference... Figure 13 Examples of various aspects of the transceiver 1320 are described. The receiver 1010 may utilize a single antenna or a set of antennas.

[0141] The communication manager 1015 can perform the following operations: determine the UE's capability to perform at least a first mode of UCI transmission and a second mode of UCI transmission, the first mode corresponding to UCI transmission on an uplink control channel that at least partially overlaps with the uplink shared channel, and the second mode corresponding to UCI transmission multiplexed on the uplink shared channel; send a configuration to the UE indicating that the UE will use the first mode of UCI transmission; and receive UCI on the uplink control channel and uplink signals on the uplink shared channel based on the sent configuration. The communication manager 1015 may be an example of aspects of the communication manager 1310 described herein.

[0142] The communication manager 1015 or its sub-components may be implemented in hardware, processor-executable code (e.g., software or firmware), or any combination thereof. If implemented in processor-executable code, the functionality of the communication manager 1015 or its sub-components may be performed by a general-purpose processor, DSP, ASIC, FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware component, or any combination thereof designed to perform the functions described in this disclosure.

[0143] The communication manager 1015 or its subcomponents may be physically located at various locations, including being distributed such that some functions are implemented by one or more physical components at different physical locations. In some examples, according to various aspects of this disclosure, the communication manager 1015 or its subcomponents may be separate and distinct components.
