Simplification of uplink control information multiplexing rules for reduced capability user equipment

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine whether to perform a simplified uplink control information (UCI) multiplexing process or to select an overlapping uplink channel with the highest priority and discard the remaining overlapping uplink channels. The UE may determine that a first symbol period of a physical uplink scheduling channel (PUSCH) is aligned with a first symbol period of a physical uplink control channel (PUCCH), and the UE may multiplex UCI with uplink data transmission. The UE may send multiplexed UCI and uplink data on the PUSCH and discard the PUCCH. The UE may perform UCI multiplexing for overlapping PUCCH and PUSCH located on the same component carrier (CC). If the PUSCH and PUCCH are located on different CCs, the UE may avoid performing UCI multiplexing and may send UCI and uplink data simultaneously on different CCs.

Technical Field

[0003] The present disclosure relates to wireless communications, and more particularly, to uplink control information (UCI) multiplexing rule simplification for reduced capability user equipment (UE). Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcasting, etc. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency and power). Examples of such multiple access systems include fourth generation (4G) systems, such as long term evolution (LTE) systems, improved LTE (LTE-A) systems or LTE-A Pro systems, and fifth generation (5G) systems that may be referred to as new radio (NR) systems. These systems may use techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA) or discrete Fourier transform 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 of which simultaneously supports communication for multiple communication devices, which may also be referred to as user equipment (UE). Some UEs may be fully capable UEs or standard UEs. Some UEs may be UEs with reduced capabilities. Summary of the invention

[0005] The described technology relates to improved methods, systems, devices and apparatuses that support simplification of uplink control information (UCI) multiplexing rules for user equipment (UE) with reduced capabilities. In summary, a UE with reduced capabilities can determine that an uplink control channel (e.g., a physical uplink control channel (PUCCH)) and an uplink shared channel (e.g., a physical uplink shared channel (PUSCH)) overlap in time. In such examples, the UE with reduced capabilities can determine whether to perform a simplified UCI multiplexing process or to select one of the overlapping uplink channels with the highest priority and discard the remaining overlapping uplink channels. For example, the UE with reduced capabilities can determine whether the first symbol period of the PUSCH is aligned with the first symbol period of the PUCCH. If they are aligned, the UE with reduced capabilities can multiplex the UCI with uplink data transmission. The UE with reduced capabilities can send the multiplexed UCI and uplink data on the PUSCH and discard the PUCCH. If they are not aligned, the reduced capability UE may avoid multiplexing UCI and uplink data and may instead transmit on the channel with the highest priority level, while dropping the other channels.

[0006] In some examples, a reduced capability UE may perform UCI multiplexing for overlapping PUCCH and PUSCH located on the same component carrier (CC). However, if the PUSCH and PUCCH are located on different CCs, the reduced capability UE may avoid performing UCI multiplexing and may instead send UCI and uplink data simultaneously on different CCs.

[0064] Some wireless communication systems may support communication with various types of user equipment (UE). For example, a standard UE or full-capability UE may be a UE that is capable of using a standard communication protocol or has a standard capability set. A reduced-capability UE (e.g., a RedCap device or RedCap UE) may be a UE that has reduced capabilities, reduced available power or a smaller battery, or a limited number of processing resources or capabilities relative to a standard capability set. A reduced-capability UE may be, for example, a wearable device such as a watch or other wristband device (e.g., a smart watch, an activity tracker), a headset, a head-mounted display (HMD), a sensor, or a device that prioritizes battery life or operates in a low power or battery efficiency mode.

[0065] In some examples, a wireless communication system (e.g., a new radio (NR) system) may support uplink control information (UCI) multiplexing. For example, an uplink control channel (e.g., a physical uplink control channel (PUCCH)) and an uplink shared channel (e.g., a physical uplink shared channel (PUSCH)) may overlap at least partially. In such examples, the UE may multiplex UCI scheduled to be sent on the PUCCH with uplink data transmission scheduled to be sent on the PUSCH, and may multiplex UCI with uplink data transmission on the PUSCH. For example, the UE may receive an uplink grant for uplink data transmission, and may also receive downlink data transmission. UCI including feedback confirmation signaling corresponding to downlink data transmission on the PUCCH and uplink data transmission on the PUSCH may overlap at least partially. In such examples, a standard UE may perform a highly complex UCI multiplexing process. Such a process may be particularly complex due to a time check process (e.g., which may be referred to as a timeline check process), cross-component carrier (CC) UCI ​​multiplexing, and the like. However, such complex procedures as part of the UCI multiplexing procedure may result in high power consumption for standard devices. Reduced capability UEs may not be able to perform such highly complex UCI multiplexing procedures or may experience excessive power loss due to such complex UCI multiplexing procedures.

[0066] Alternatively, to avoid excessive power consumption, the UE with reduced capability may perform a simplified UCI multiplexing process, or may avoid performing the UCI multiplexing process under some conditions. For example, the UE with reduced capability may determine whether the first symbol of the PUCCH and the first symbol of the PUSCH overlapping with the PUCCH are aligned in time. If the first symbols of the corresponding PUCCH and PUSCH are aligned (for example, if the first symbol of the PUCCH is a threshold time amount away from the first symbol of the PUSCH), the UE with reduced capability may multiplex the UCI message with the uplink data transmission (for example, the payload of the UCI may be multiplexed with the uplink message on the PUSCH, and the PUCCH may be discarded) without performing complex time checks. In some examples, the PUCCH may be scheduled on the first CC, and the PUSCH may be scheduled on the second CC. Performing UCI multiplexing across multiple CCs may be a time-consuming process, resulting in large power consumption. Instead of multiplexing UCI and uplink data transmission on a single CC, the UE with reduced capability may send UCI on the PUCCH on the first CC, and may send an uplink data message on the PUSCH on the second CC.

[0067] Certain aspects of the subject matter described herein may be implemented to achieve one or more advantages. The described techniques may support improvements in system efficiency and power efficiency. A UE with reduced capabilities may effectively and efficiently determine whether to perform a simplified UCI multiplexing process, thereby reducing power consumption, improving efficiency, extending battery life, reducing system congestion, improving system reliability, and increasing user experience.

[0068] Various aspects of the present disclosure are first described in the context of a wireless communication system. Various aspects of the present disclosure are further illustrated and described with reference to multiplexing schemes and process flows. Various aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow diagrams relating to UCI multiplexing rule simplification for UEs with reduced capabilities.

[0069] Figure 1 An example of a wireless communication system 100 supporting simplification based on UCI reuse rules for UEs with reduced capabilities according to various aspects of the present disclosure is 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 communications, ultra-reliable (e.g., mission-critical) communications, low-latency communications, or communications with low-cost and low-complexity devices, or any combination thereof.

[0070] Base stations 105 may be dispersed throughout a geographic area to form a wireless communication system 100, and may be devices of different forms or with different capabilities. Base stations 105 and UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110, and UEs 115 and base stations 105 may establish one or more communication links 125 over the coverage area 110. Coverage area 110 may be an example of a geographic area over which base stations 105 and UEs 115 may support transmission of signals according to one or more radio access technologies.

[0071] UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. UEs 115 may be devices of different forms or with different capabilities. Figure 1Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul network (IAB) nodes, or other network devices), such as Figure 1 shown.

[0072] The base stations 105 may communicate with the core network 130, or communicate with each other, or perform both operations. For example, the base stations 105 may be connected to the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3 or other interfaces). The base stations 105 may communicate with each other directly (e.g., directly between the base stations 105) on the backhaul links 120 (e.g., via X2, Xn or other interfaces), or communicate with each other indirectly (e.g., via the core network 130), or perform both operations. In some examples, the backhaul links 120 may be or include one or more wireless links.

[0073] One or more of the base stations 105 described herein may include or may be referred to by a person of ordinary skill in the art as a base station transceiver, a radio base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNodeB, eNB), a next generation Node B or a Gigabit Node B (either of which may be referred to as a gNB), a Home Node B, a Home Evolved Node B, or other appropriate terminology.

[0074] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other appropriate terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client, among other examples. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, among other examples, which may be implemented in various items such as appliances, or vehicles, meters, and among other examples.

[0075] The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, such as Figure 1 shown.

[0076] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating operations for the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink CCs and one or more uplink CCs. Carrier aggregation may be used with both frequency division duplex (FDD) CCs and time division duplex (TDD) CCs.

[0077] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be placed according to a channel grid to be discovered by a UE 115. A carrier may operate in a standalone mode, where a UE 115 performs initial acquisition and connection via a carrier, or a carrier may operate in a non-standalone mode, where a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0078] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in FDD mode) or may be configured to carry both downlink and uplink communications (e.g., in TDD mode).

[0079] A carrier may be associated with a particular bandwidth of a radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a number of determined bandwidths for a carrier of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., base stations 105, UEs 115, or both) may have a hardware configuration that supports communication on a particular carrier bandwidth, or may be configurable to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., subband, BWP) or all of the carrier bandwidth.

[0080] The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, wherein the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements received by the UE 115 and the higher the order of the modulation scheme, the higher the data rate for the UE 115 can be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communication with the UE 115.

[0081] One or more numerologies for a carrier may be supported, where the numerologies may include subcarrier spacing (Δf) and cyclic prefixes. A carrier may be divided into one or more BWPs with the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications for a UE 115 may be limited to the one or more active BWPs.

[0082] The basic time unit (which may be referred to as T s =1 / (Δf max ·N f ) seconds sampling period, where Δf maxIt can represent the maximum supported subcarrier spacing, and N f The time intervals for the base station 105 or the UE 115 may be expressed as multiples of a maximum supported discrete Fourier transform (DFT) size). The time intervals of the communication resources may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0083] Each frame may include a plurality of 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., depending on the length of a cyclic prefix added in front of each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of micro-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0084] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in the form of a burst of shortened TTIs (sTTIs)).

[0085] Physical channels may be multiplexed on a carrier according to various techniques. For example, one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique may 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 a physical control channel may be defined by the number of symbol periods and may extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a group of UEs 115. For example, one or more of the UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates at one or more aggregation levels arranged in a cascaded manner. The aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0086] Each base station 105 can provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots or other types of cells, or any combination thereof). The term "cell" can refer to a logical communication entity used to communicate with the base station 105 (e.g., on a carrier), and can be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID) or other identifier) ​​for distinguishing adjacent cells. In some examples, a cell can also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors (such as the capabilities of the base station 105), the range of such a cell can range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell can be or include a building, a subset of a building, or an external space between or overlapping geographic coverage areas 110, as well as other examples.

[0087] A macro cell typically covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 115 with a service subscription to a network provider that supports the macro cell. A small cell may be associated with a lower power base station 105 than a macro cell, and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to a UE 115 with a service subscription to a network provider, or may provide restricted access to a UE 115 associated with a small cell (e.g., a UE 115 in a closed subscriber group (CSG), a UE 115 associated with a user in a residence or office). A base station 105 may support one or more cells, and may also support the use of one or more CCs to communicate on one or more cells.

[0088] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0089] In some examples, the base stations 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 the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for respective geographic coverage areas 110 using the same or different radio access technologies.

[0090] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timing, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timing, and in some examples, transmissions from different base stations 105 may not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operation.

[0091] Some UEs 115 (e.g., MTC or IoT devices) may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents the information to a human interacting with the application. Some UEs 115 may be designed to collect information or implement automated 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 business billing.

[0092] Some UEs 115 may be configured to employ an operating mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception rather than transmission and reception simultaneously). 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 participating in active communications, when operating on a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0093] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE115 can be designed to support ultra-reliable, low-latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication 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 prioritization of services, 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 can be used interchangeably in this article.

[0094] In some examples, UE 115 may also be able to communicate directly with other UE 115 on a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within a geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some examples, groups of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, wherein each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0095] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these items. Vehicles can use signals to send information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in a V2X system can communicate with roadside infrastructure (such as a roadside unit), or communicate with a network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or both.

[0096] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connection, and other access, routing or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function unit (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function unit (UPF)) for routing packets to an external network or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by a base station 105 associated with the core network 130. User IP packets may be transmitted through a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to a network operator IP service 150. Operator IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0097] Some of the network devices (e.g., base stations 105) may include subcomponents such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with the UE 115 through one or more other access network transport entities 145 (which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs)). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or merged into a single network device (e.g., base station 105).

[0098] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves may be sufficient to penetrate structures for macro cells to provide service to UEs 115 located indoors. Transmissions on UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0099] The wireless communication system 100 may also operate in a super high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also referred to as a centimeter band) or in an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as a millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and base station 105, and the EHF antennas of the corresponding devices may be even smaller and more closely spaced than UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, compared to SHF or UHF transmissions, the propagation of EHF transmissions may suffer from even greater atmospheric attenuation and shorter distances. The technology disclosed herein may be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may differ according to countries or regulatory agencies.

[0100] The wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 can employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band (such as the 5 GHz industrial, scientific, and medical (ISM) band). When operating in an unlicensed radio frequency spectrum band, devices (such as base stations 105 and UEs 115) can employ carrier sensing for conflict detection and avoidance. In some examples, operations in unlicensed bands can be based on a carrier aggregation configuration combined with CCs operating in a licensed band (e.g., LAA). Operations in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, as well as other examples.

[0101] The base station 105 or UE 115 may be equipped with multiple antennas, which may be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operations 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 the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having antenna ports of a number of rows and columns that the base station 105 may use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals sent via the antenna ports.

[0102] The base station 105 or UE 115 can use MIMO communication to exploit multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technology may be referred to as spatial multiplexing. For example, a transmitting device may send multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) (where multiple spatial layers are sent to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are sent to multiple devices).

[0103] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to form or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array so that some signals propagating in a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals transmitted via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of the antenna elements may be defined by a set of beamforming weights associated with a specific orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0104] As part of the beamforming operation, the base station 105 or the UE 115 may use beam scanning techniques. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communications with the UE 115. The base station 105 may send some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, the base station 105 may send signals based on 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 the base station 105) or by a receiving device (such as the UE 115)) to identify a beam direction for subsequent transmission or reception by the base station 105.

[0105] Base station 105 may transmit some signals (e.g., data signals associated with a particular receiving device (e.g., UE 115)) in a single beam direction (e.g., a direction associated with the receiving device). In some examples, the beam direction associated with transmission along the 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 of the 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 having the highest signal quality or otherwise acceptable signal quality.

[0106] In some examples, transmissions by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may generate a combined beam for transmission (e.g., from the base station 105 to the UE 115) using a combination of digital precoding or radio frequency beamforming. The UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. The base station 105 may send reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)) that may be precoded or not precoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type of codebook, a linear combination type of codebook, a port selection type of codebook). Although these techniques are described with reference to signals sent by base station 105 in one or more directions, UE 115 may employ similar techniques to send signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115) or to send signals in a single direction (e.g., to send data to a receiving device).

[0107] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from the base station 105, the receiving device (e.g., UE 115) can try multiple reception configurations (e.g., directional listening). For example, the receiving device can try multiple reception directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different reception beamforming weight sets applied to the signals received at multiple antenna elements of the antenna array (e.g., different directional listening weight sets), or by processing the received signals according to different reception beamforming weight sets applied to the signals received at multiple antenna elements of the antenna array (any of the above operations may be referred to as "listening" according to different reception configurations or reception directions). In some examples, the receiving device can use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned on a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0108] The wireless communication system 100 may be a packet-based network operated according to a layered protocol stack. In the user plane, the communication at the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly to transmit on a logical channel. The medium access control (MAC) layer may perform priority handling and multiplexing of logical channels to transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration, and maintenance of an RRC connection (which supports radio bearers for user plane data) between a UE 115 and a base station 105 or a core network 130. At the physical layer, transport channels may be mapped to physical channels.

[0109] UE 115 and base station 105 can support retransmission of data to increase the possibility that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technology for increasing the possibility that data is correctly received 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 the 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, wherein the device can provide HARQ feedback for data received in previous symbols in the slot in a specific slot. In other cases, the device can provide HARQ feedback in subsequent slots or according to some other time interval.

[0110] In some examples, the UE 115 with reduced capabilities may determine that an uplink control channel (e.g., PUCCH) and an uplink shared channel (e.g., PUSCH) overlap in time. In such examples, the UE with reduced capabilities may determine whether to perform a simplified UCI multiplexing process or to select one of the overlapping uplink channels with the highest priority and discard the remaining overlapping uplink channels. For example, the UE 115 with reduced capabilities may determine whether the first symbol period of the PUSCH is aligned with the first symbol period of the PUCCH. If they are aligned, the UE 115 with reduced capabilities may multiplex the UCI with the uplink data transmission. The UE 115 with reduced capabilities may send the multiplexed UCI and uplink data on the PUSCH and discard the PUCCH. If they are not aligned, the UE 115 with reduced capabilities may avoid multiplexing the UCI and uplink data and may instead send on the channel with the highest priority level and discard other channels.

[0111] In some examples, the reduced capability UE 115 may perform UCI multiplexing for overlapping PUCCH and PUSCH located on the same CC. However, if the PUSCH and PUCCH are located on different CCs, the reduced capability UE 115 may avoid performing UCI multiplexing and may instead send UCI and uplink data simultaneously on different CCs.

[0112] Figure 2 An example of a wireless communication system 200 that supports UCI multiplexing rule simplification for reduced capability UEs according to aspects of the present disclosure is shown. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. The wireless communication system 200 may include a base station 105-a, a UE 115-a, and a UE 115-b, which may be referenced Figure 1 Examples of corresponding devices described. UE 115-a can be a standard UE 115. UE 115-b can be a UE 115 with reduced capabilities.

[0113] The base station 105-a may communicate with various UEs 115. For example, the base station 105-a may communicate with the UE 115-a via a bidirectional communication link 205-a. The UE 115-a may perform a UCI multiplexing process. For example, if the PUCCH 230-a and the PUSCH 215-a overlap in time, the UE 115-a may multiplex the UCI from the PUCCH 230-a with the uplink data from the PUSCH 215-a on the PUSCH 215-a. The UCI scheduled on the overlapping PUCCH 230-a may include acknowledgment feedback (e.g., an acknowledgment (ACK) message or a negative acknowledgment (NACK) message), a periodic channel state information (P-CSI) report, a semi-persistent CSI (SP-CSI) report, a HARQ ACK and a scheduling request (SR), a scheduling request, a HARQ ACK with an SR and CSI, or any combination thereof. As described herein, UCI multiplexing may include multiplexing any of the above-described UCIs with uplink data on the PUSCH.

[0114] In some examples, the UE 115-a and the base station 105-a may multiplex UCI including, for example, HARQ ACK feedback. The base station 105-a may send a physical downlink control channel (PDCCH) 210-a including a scheduling grant for uplink data transmission on a PUSCH 215-a. The base station 105-a may also send a PDCCH 220-a with a downlink grant for downlink data transmission on a physical downlink shared channel (PDSCH) 225-a. The UE 115-a may send an acknowledgment feedback message (e.g., an ACK message or a NACK message) on a PUCCH 230-a associated with the downlink data transmission sent on the PDSCH 225-a. The PUCCH 230-a and the PUSCH 215-a may at least partially overlap in time. In such examples, the UE 115-a may perform a complex UCI multiplexing process, as described with reference to Figure 3 For example, UE 115-a may perform the following steps as described in more detail. Figure 3 Describe the regular inspection process or reference Figure 5 Such a UCI multiplexing process for a standard UE 115 may consume excessive power, depend on the use of unavailable computing resources, etc., thereby causing one or more failed transmissions, system congestion, increased latency, and a degraded user experience.

[0115] The base station 105-a may also communicate with the UE 115-b via the bidirectional communication link 205-b. The UE 115-b may be a reduced capability UE. In some examples, the base station 105-b may send a PDCCH 210-b including a scheduling grant for uplink data transmission on a PUSCH 215-b. The base station 105-a may also send a PDCCH 220-b with a downlink grant for downlink data transmission on a PDSCH 225-b. The UE 115-b may send an acknowledgment feedback message (e.g., an ACK message or a NACK message) associated with the downlink data transmission sent on the PDSCH 225-b on a PUCCH 230-b. The PUCCH 230-b and the PUSCH 215-b may at least partially overlap in time. In order to reduce power consumption, or to avoid complex processes that exceed its capabilities, the UE 115-b may perform a simplified UCI multiplexing process, as described with reference to Figure 4 and Figure 6 In some examples, UE 115-a may avoid performing cross-CC UCI multiplexing, as described in more detail. Figure 5 and Figure 6 Described.

[0116] Figure 3 An example of a multiplexing scheme 300 that supports UCI multiplexing rule simplification for reduced capability UEs in accordance with aspects of the present disclosure is shown. In some examples, multiplexing scheme 300 can implement aspects of wireless communication system 100 and wireless communication system 200.

[0117] In some examples, base station 105 and UE 115 (e.g., a standard UE) can communicate, as shown in FIG. Figure 2Described. The base station 105 may send an uplink grant 305 to the UE 115. The uplink grant 305 may be included in the PDCCH and may indicate resources for uplink data transmission on the PUSCH 310. The base station 105 may also send a downlink grant 315 on the PDCCH, which includes a grant of resources for downlink data transmission on the PDSCH 320. The UE 115 may send an acknowledgment feedback message (e.g., an ACK message or a NACK message) indicating whether the UE 115 has received the downlink data transmission on the PDSCH 320. The UE 115 may send acknowledgment feedback information on the PUCCH 325. In some examples, the PUSCH 310 and the PUCCH 325 may overlap at least partially in time. In such a case, the UE 115 may perform a UCI multiplexing process. For example, the UE 115 may multiplex the payload of the acknowledgment feedback message with uplink data transmission on the PUSCH 310 and may drop the PUCCH 325 (eg, disconnect and avoid communicating on the PUCCH 325).

[0118] If the UE 115 is a standard UE, as part of the UCI multiplexing process, the UE 115 may perform a time check for the PUSCH 310 and the PUCCH 325. The UE 115 may determine whether the PUSCH 310 and the PUCCH 325 are legitimate candidates for UCI multiplexing by performing the time check. That is, if the PUSCH 310 and the PUCCH 325 pass the time check, the UE 115 may determine that they are legitimate candidates for the UCI multiplexing process and may multiplex the confirmation feedback message and the uplink data transmission on the PUSCH 310.

[0119] To perform the time check, UE 115 may determine whether it has sufficient processing power (processing power 1) to receive PDSCH 320, process PDSCH 320, prepare PUCCH 325, and ) potentially multiplexes an acknowledgement message for PUCCH 325 and an uplink data transmission for PUSCH 310 within time 2. UE 115 may also determine whether it has sufficient processing power to receive uplink grant 305, process uplink grant 305, prepare PUSCH 310, and ) can potentially multiplex confirmation feedback messages and uplink data transmissions within a period of 1 second. To do this, the UE 115 can identify a reference time 330. The UE 115 can identify a first symbol period of an overlapping channel. For example, the first symbol period PUCCH 325 can be earlier than the first symbol period of PUSCH 310, so the reference time 330 can be aligned with the symbol boundary of the first symbol period of PUCCH 325. The UE 115 can then determine whether the uplink grant 305 precedes the reference time 330 by at least time 2 and whether the PDSCH 320 precedes the PUCCH 325 by at least time 1. That is, if the last PDSCH symbol of the PDSCH 320 corresponding to the confirmation feedback message on the PUCCH 325 is before the reference time 330 minus T1, then the PUCCH 325 can be a legitimate candidate for UCI multiplexing. If both the uplink grant 305 and the downlink grant 315 precede the reference time 330 by at least time 2, then the PUSCH 310 and the PUCCH 325 may be legitimate candidates for UCI multiplexing. In such a case, the UE 115 may perform the UCI multiplexing process based on the successful time check. However, if the PDSCH 320 does not precede the reference time 330 by time 1, or if the uplink grant 305 or the downlink grant 315 does not precede the reference time 330 by at least time 2, then the UE 115 may avoid performing the UCI multiplexing process on the PUSCH 310 and the PUCCH 325.

[0120] In some examples, UE 115 may calculate time 1 and time 2 based on one or more parameters. For example, UE 115 may determine capability 1 and capability 2, and may calculate time 1 and time 2, respectively, based thereon. In some examples, UE 115 may calculate time 1 and time 2 based on a digital scheme of one or more channels (e.g., transmission time interval (TTI) duration, subcarrier spacing (SCS), etc.). For example, time 1 and time 2 may be based on a digital scheme of one or more of the following: a PDCCH carrying an uplink grant 305, a PUSCH 310, a PDCCH carrying a downlink grant 315, a PDSCH 320, a PUCCH 325, or a combination thereof. Such calculations may use computing resources or consume a lot of power, or both.

[0121] The reduced-capability UE 115 may not have sufficient power or computing resources available to perform such expensive calculations or to perform such expensive time check procedures. Alternatively, the reduced-capability UE 115 may perform a simplified UCI procedure that omits or simplifies the time check procedure, as described in reference to Figure 4 Described in more detail.

[0122] Figure 4An example of a multiplexing scheme 400 that supports UCI multiplexing rule simplification for reduced capability UEs in accordance with aspects of the present disclosure is shown. In some examples, multiplexing scheme 400 can implement aspects of wireless communication system 100 and wireless communication system 200.

[0123] In some examples, base station 105 can communicate with UE 115, as shown in FIG. Figure 2 Described. The base station 105 may send an uplink grant 405 to the UE 115. The uplink grant 405 may be included in the PDCCH and may indicate resources for uplink data transmission on the PUSCH 410. The base station 105 may also send a downlink grant 415 on the PDCCH, which includes a grant of resources for downlink data transmission on the PDSCH 420. The UE 115 may send an acknowledgment feedback message (e.g., an ACK message or a NACK message) indicating whether the UE 115 has received the downlink data transmission on the PDSCH 420. The UE 115 may send acknowledgment feedback information on the PUCCH 425. In some examples, the PUSCH 410 and the PUCCH 425 may overlap at least partially in time. In such a case, in the case where the UE 115 is a UE with reduced capability, the UE 115 may perform a simplified UCI multiplexing process. For example, the UE 115 may multiplex the payload of the acknowledgment feedback message with uplink data transmission on the PUSCH 410 and may drop the PUCCH 425 .

[0124] The reduced capability UE 115 may perform a simplified UCI multiplexing process. That is, the time check for the reduced capability UE may be removed from the process. For example, the UE 115 may simply determine whether the first symbol period of the PUSCH 410 and the first symbol period of the PUCCH 425 are aligned. If the first symbol periods of the PUSCH 410 and the PUCCH 425 are aligned in time, the UE 115 may multiplex the confirmation feedback message with the uplink data transmission on the PUSCH 420, as described herein.

[0125] When the independent timing requirements are met, the UE 115 may perform UCI multiplexing. For example, when the uplink grant 405 precedes the PUSCH 410 by at least time T2, the UE 115 may be able to multiplex the confirmation feedback message and the uplink data transmission. T2 may represent the amount of time used to receive the uplink grant 405 and prepare the PUSCH 410 and multiplex the confirmation feedback message and the uplink data transmission. Similarly, when the PDSCH 420 precedes the PUCCH 425 by at least time T1, the UE 115 may be able to multiplex the confirmation feedback message and the uplink data transmission. However, the UE 115 may assume that the base station 105 can schedule the PUSCH 410 and the PUCCH 415 to meet T1 and T2. Therefore, the UE 115 can avoid consuming resources to calculate T1 and T2. In addition, the UE 115 can perform UCI multiplexing without performing a joint time check for the PUSCH 410 and the PUCCH 425. In some examples, UE 115 may not calculate T1 and T2, and may avoid determining whether PUSCH 410 and PUCCH 425 are legitimate candidates based on a time check. Instead, UE 115 may simply determine whether the first symbol of PUSCH 410 and the first symbol of PUCCH 425 are aligned in time. If so, UE 115 may multiplex the confirmation feedback message and the uplink data transmission on PUSCH 410. If not, UE 115 may send the confirmation feedback message on PUCCH 425 and may send the uplink data transmission on PUSCH 410.

[0126] In some examples, if the symbol boundaries of the first symbol period of PUSCH 410 and the first symbol period of PUCCH 425 are the same, then UE 115 can consider PUSCH 410 and PUCCH 425 aligned in time. In some examples, if the first symbol period of PUSCH 410 and the first symbol period of PUCCH 425 are sufficiently close in time to each other, then UE 115 can consider PUSCH 410 and PUCCH 425 aligned in time. For example, UE 115 can determine whether the first symbol period of PUSCH 410 is within a threshold amount of time or a threshold number of TTIs (e.g., symbols, time slots, etc.) of the first symbol period of PUCCH 425.

[0127] If the PUSCH 410 and PUCCH 425 are not aligned in time, the UE 115 can avoid multiplexing the confirmation feedback message and the uplink data transmission. Alternatively, the UE 115 can determine which of the PUSCH 410 and PUCCH 425 has a higher priority level. In such a case, the UE 115 can transmit on the uplink channel with the highest priority level and can discard all other overlapping uplink channels. For example, the UE 115 can determine which of the PUSCH 410 and PUCCH 425 has a higher priority level.

[0128] The UE 115 may determine which of the PUSCH 410 and the PUCCH 425 has the highest priority level based on the priority tag or priority indicator for each channel. The UE 115 may identify the priority indicator for each channel based on a corresponding grant (e.g., an uplink grant 405 for the PUSCH 410 and a downlink grant 415 for the PUCCH 425), or based on configuration information (e.g., received via higher layer signaling such as RRC signaling, or based on standardized information, one or more priority rules, etc.). In some examples, the downlink grant 415 may include a priority indicator for the PUCCH 425. In some examples, the downlink grant 415 may include a priority indicator for the PDSCH 420, and the UE 115 may determine the priority level for the PUCCH 425 based on the priority indicator for the PDSCH 420. For example, UE 115 may compare the priority indicator for PUSCH 410 with the priority indicator for PDSCH 420 .

[0129] UE 115 may determine which uplink channel has the highest priority level based on timing. For example, UE 115 may determine which of PUSCH 410 and PUCCH 425 is the highest priority channel based on which channel has the earliest starting OFDM symbol. That is, if the first symbol period of PUSCH 410 precedes the first symbol period of PUCCH 425, then PUSCH 410 is a priority channel and PUCCH 425 is a non-priority channel. In such an example, UE 115 may multiplex the confirmation feedback message and the uplink data transmission on PUSCH 410 and may discard PUCCH 425.

[0130] PUSCH 410 and PUCCH 425 may be located on the same CC. In some examples, PUSCH and PUCCH may overlap across different CCs. In such examples, the reduced capability UE 115 may avoid performing the UCI multiplexing process, as described in reference to Figure 5 Described in more detail.

[0131] Figure 5 An example of a multiplexing scheme 500 that supports UCI multiplexing rule simplification for reduced capability UEs in accordance with aspects of the present disclosure is shown. In some examples, multiplexing scheme 500 can implement aspects of wireless communication system 100 and wireless communication system 200.

[0132] In some examples, the base station 105 can communicate with the UE 115 (e.g., a standard capability UE 115 or a reduced capability UE 115). For example, the base station 105 can send a downlink grant 505 to the UE 115 on the PDCCH. The downlink grant 505 can include a downlink grant of resources for downlink data transmission on the PDSCH 510. In such an example, the UE 115 can send an acknowledgment feedback message (e.g., an ACK or NACK message) on the PUCCH 515, which indicates whether the UE 115 has received the downlink data transmission on the PDSCH 510. The base station 105 can also send one or more uplink grants 520 on the PDCCH. For example, the uplink grant 520-a can include a grant of resources for a first uplink data transmission on the PUSCH 525-a, and the uplink grant 520-b can include a grant of resources for uplink transmission on the PUSCH 525-b.

[0133] In some examples, PUCCH 515 may be located on a first CC, such as primary CC (PCC) 530, and PUSCH 525 may be located on a second CC, secondary CC (SCC) 535. PCC 530 may be a 15kHz CC, and SCC 535 may be a 30kHz CC.

[0134] The standard UE 115 may be able to perform a cross-CC UCI multiplexing process according to a set of multiplexing rules. For example, the standard UE 115 may multiplex overlapping PUCCH transmissions into the same resource (e.g., resource Z) per PUCCH slot according to the digital scheme of the PUCCH CC (e.g., PCC 530). For UCI that does not include a scheduling request in resource Z, the standard UE 115 may multiplex the UCI in resource Z onto a PUSCH 525 that at least partially overlaps with the PUCCH according to the following priority rules. As long as non-periodic channel state information (A-CSI) overlaps with resource Z, the standard UE 115 may prioritize multiplexing the UCI with the PUSCH that includes A-CSI. As a second priority, the standard UE 115 may multiplex the UCI with the earliest PUSCH slot based on the start of the earliest slot (e.g., PUSCH 525-a, not PUSCH 525-b). If one or more PUSCHs 525 overlap with resource Z in the earliest PUSCH timeslot, the standard UE 115 may prioritize the dynamically granted PUSCH 525 over the PUSCH configured by the corresponding higher layer signaling, semi-periodic scheduling, or periodic message (e.g., ConfiguredGrantConfig or semiPersistentOnPUSCH). Then, the standard UE 115 may prioritize the PUSCH on the serving cell with the smaller CC serving cell index over the PUSCH on the CC serving cell with the largest serving cell index. Finally, the standard UE 115 may prioritize earlier PUSCH transmissions over later PUSCH transmissions. At least some of such priority rules may be applicable in the case where the digital schemes of the PCC 530 and the SCC 535 are the same or different. Performing such cross-CC UCI multiplexing may result in power consumption that exceeds the capacity of the UE 115 with reduced capabilities.

[0135] In some examples, the reduced capability UE 115 may determine whether the overlapping PUCCH 515 and PUSCH 525 are located on the same CC. If the overlapping PUCCH 515 and PUSCH 525 are located on the same CC, the reduced capability UE 115 may perform a UCI multiplexing process as described in reference to Figure 6 For example, the UE 115 with reduced capabilities may perform the following steps as described in reference to Figure 4If the overlapping PUCCH 515 and PUSCH 525 are not located on the same CC (e.g., if PUCCH 515 is located on PCC 530, and PUSCH 525-a and PUSCH 525-b are located on SCC 535), the reduced capability UE 115 may send an acknowledgment feedback message on PUCCH 515 on PCC 535 and may simultaneously send an uplink data transmission on PUSCH 525-a or PUSCH 525-b on SCC 535. By avoiding performing cross-CC UCI multiplexing, the reduced capability UE 115 may save power, thereby extending battery life and improving user experience.

[0136] Figure 6 An example of a multiplexing scheme 600 that supports simplification of UCI multiplexing rules for reduced capability UEs in accordance with aspects of the present disclosure is shown. In some examples, multiplexing scheme 500 can implement aspects of wireless communication systems 100 and 200.

[0137] In some examples, the base station 105 can communicate with the UE 115 (e.g., a standard capability UE 115 or a reduced capability UE 115). For example, the base station 105 can send a downlink grant 605 to the UE 115 on the PDCCH. The downlink grant 605 can include a downlink grant of resources for downlink data transmission on the PDSCH 610. In such an example, the UE 115 can send an acknowledgment feedback message (e.g., an ACK or NACK message) on the PUCCH 615-a, which indicates whether the UE 115 has received the downlink data transmission on the PDSCH 610. The base station 105 can also send one or more uplink grants 620 on the PDCCH. For example, the uplink grant 620-a can include a grant of resources for a first uplink data transmission on the PUSCH 625-a, and the uplink grant 620-b can include a grant of resources for uplink transmission on the PUSCH 625-b.

[0138] In some examples, PUCCH 615-a can be located on a first CC (e.g., PCC 630) and PUSCH 625 can be located on a second CC (SCC 635). PCC 630 can be a 15kHz CC (a CC using 15kHz subcarrier spacing) and SCC 635 can be a 30kHz CC (a CC using 30kHz subcarrier spacing).

[0139] The standard UE 115 may be able to perform a cross-CC UCI multiplexing process according to a set of multiplexing rules. For example, the standard UE 115 may multiplex overlapping PUCCH transmissions into the same resource (e.g., resource Z) of each PUCCH slot according to the digital scheme of the PUCCH CC (e.g., PCC 630). For UCI that does not include a scheduling request in resource Z, the standard UE 115 may multiplex the UCI in resource Z onto a PUSCH 625 that at least partially overlaps with the PUCCH according to the following priority rules. As long as non-periodic channel state information (A-CSI) overlaps with resource Z, the standard UE 115 may prioritize multiplexing the UCI with the PUSCH including the A-CSI. As a second priority, the standard UE 115 may multiplex the UCI with the earliest PUSCH slot based on the start of the earliest slot (e.g., PUSCH 625-a, not PUSCH 625-b). If one or more PUSCHs 625 overlap with resource Z in the earliest PUSCH timeslot, the standard UE 115 may prioritize the dynamically granted PUSCH 625 over the PUSCH configured by the corresponding higher layer signaling, semi-periodic scheduling, or periodic message (e.g., ConfiguredGrantConfig or semiPersistentOnPUSCH). Then, the standard UE 115 may prioritize the PUSCH on the serving cell with the smaller CC serving cell index over the PUSCH on the CC serving cell with the largest serving cell index. Finally, the standard UE 115 may prioritize earlier PUSCH transmissions over later PUSCH transmissions. At least some of such priority rules may be applicable in the case where the digital schemes of the PCC 630 and the SCC 635 are the same or different. Performing such cross-CC UCI multiplexing may result in power consumption that exceeds the capacity of the UE 115 with reduced capabilities.

[0140] In some examples, the reduced capability UE 115 may identify overlapping PUCCH and PUSCH on the same CC. In such examples, the reduced capability UE 115 may multiplex UCI and uplink data on the PUSCH and discard the PUCCH. For example, the PUCCH 615-b may be located on the same CC (e.g., SCC 635) as one or more PUSCHs 625. In such examples, the reduced capability UE 115 may multiplex UCI and uplink data and send the multiplexed UCI and uplink data on the PUSCH 625. Therefore, the reduced capability UE 115 may discard the PUCCH 615-b.

[0141] However, if the PUCCH 615 and one or more PUSCHs 625 are on different CCs, the reduced capability UE 115 can avoid performing UCI multiplexing. For example, the PUCCH 615-a can be located on the PCC 630, and the one or more PUSCHs 625 can be located on the SCC 635. In such a case, the reduced capability UE 115 can send UCI on the PUCCH 615-a of the PCC 630, which includes an acknowledgment feedback message for the PDSCH 610, and can simultaneously send uplink data transmission on the PUSCH 625-a or PUSCH 625-b on the SCC 635. By avoiding performing cross-CC UCI multiplexing, the reduced capability UE 115 can save power, thereby extending battery life and improving user experience.

[0142] Figure 7 An example of a process flow 700 for supporting UCI multiplexing rule simplification for reduced capability UEs according to aspects of the present disclosure is shown. In some examples, the process flow 700 can implement aspects of the wireless communication systems 100 and 200. The process flow 700 can include a UE 115-c and a base station 105-b, which can be referenced Figure 1 and Figure 2 Examples of corresponding devices described.

[0143] In some examples, at 710, the base station 105-b may send a downlink data transmission to the UE 115-c. The base station 105-b may send the downlink data on a downlink shared channel (e.g., PDSCH).

[0144] The base station 105-b may send a downlink control information (DCI) message to the UE 115-c at 715. The DCI may include a grant of resources for uplink data transmission on an uplink shared channel (eg, PUSCH).

[0145] At 720, the UE 115-c may determine that a first symbol period of the PUSCH is aligned with a first symbol period of the PUCCH used for UCI. The UE 115-c may determine that the first symbol period of the PUSCH is within a threshold amount of time or a threshold number of TTIs from the first symbol period of the PUCCH.

[0146] The UCI may include CSI (e.g., CSI report, P-CSI report, SP-CSI report), confirmation feedback (ACK or NACK signaling), SR, or a combination thereof (e.g., HARQ-ACK+SR on PUCCH, HARQ-ACK+SR+CSI on PUCCH, etc.). In some examples, the UCI may include confirmation feedback for a received downlink transmission. For example, the UCI may include an ACK message or a NACK message corresponding to the downlink data received at 710.

[0147] At 725, the UE 115-c may multiplex the UCI and the uplink data transmission for simultaneous transmission on the PUSCH. The UE 115-c may multiplex the UCI and the uplink data transmission based on determining that the first symbol period of the PUSCH is aligned with the first symbol period of the PUCCH.

[0148] Multiplexing the UCI and uplink data transmission may include multiplexing the payload of the PUCCH (eg, UCI) with the payload of the PDSCH (eg, uplink transmission) and sending the multiplexed payload. The UE 115-c may drop the PUCCH.

[0149] In some examples, UE 115-a may determine that a first time between receiving downlink data transmission at 710 and sending confirmation feedback and uplink data transmission at 730 satisfies a first threshold time, and may determine that a second time between receiving DCI at 715 and sending confirmation feedback and uplink data transmission at 730 satisfies a second threshold time, wherein multiplexing the confirmation feedback and uplink data transmission is based on the first time satisfying the first threshold time and the second time satisfying the second threshold time. In such examples, UE 115-c may multiplex UCI and uplink data at 725 based on satisfying both times. In some examples, UE 115-c may assume that the times are met and may make the determination autonomously without wasting computing resources or time. For example, the base station 105-b may determine a first time (e.g., a first minimum time for receiving a downlink grant for downlink data at 715, receiving downlink data transmission at 710, processing the downlink data, and multiplexing confirmation feedback for the downlink data with the uplink data at 725) and a second time (e.g., a second minimum time for receiving DCI, preparing uplink data, and multiplexing UCI with the uplink data) at 705, and may schedule PUCCH for UCI and PUSCH to meet the first time and the second time. In such an example, the base station 105-b may send a DCI including a downlink grant for downlink data at 710, send the DCI at 715, and schedule the PUCCH to meet the first time and the second time.

[0150] In some examples, UE 115-c may multiplex UCI and uplink data transmission based on UE type. For example, UE 112-c may identify that it is a first type of UE (e.g., a RedCap UE) and may multiplex uplink data transmission and UCI based on the PUCCH and PDSCH being aligned and based on its status as a RedCap. Other UE types (e.g., standard UEs) may perform more complex UCI multiplexing procedures (e.g., may perform complex timing checks).

[0151] At 730, UE 115-c may send multiplexed UCI and uplink data transmissions on PUSCH. Base station 105-b may receive and decode the multiplexed UCI and uplink data transmissions. Base station 105-b may anticipate the multiplexed UCI and uplink data transmissions based on the UE type of UE 115-c (e.g., RedCap UE) and the alignment between PUCCH and PUSCH. Thus, if base station 105-b schedules PUCCH and PUSCH that are aligned in time (as determined by UE 115-c at 720), and if UE 115-c is a RedCap UE, and if base station 105-b has scheduled PUCCH and PUSCH to satisfy the first time and the second time, as described herein, then base station 105-b may monitor, receive, and decode the multiplexed UCI and uplink data transmissions. However, if none of the above conditions are met, the base station 105-b may only monitor, receive, and decode one overlapping channel (eg, the overlapping channel with the highest priority).

[0152] In some examples, during a TTI different from a TTI in which the PUSCH and the PUCCH overlap, the UE 115-c may determine that the first uplink channel at least partially overlaps with the second uplink channel, and may determine to discard one of the two uplink channels based on identifying that a first symbol period of the first uplink channel is not aligned with a first symbol period of the second uplink channel. The UE 115-c may determine that the first uplink channel has a first priority level and the second uplink channel has a second priority level, the second priority level being a lower priority than the first priority level, and may send an uplink message on the first uplink channel based on the higher priority level of the first uplink channel, and may discard the second uplink channel. The UE 115-c may determine which of the two uplink channels has a higher priority level by identifying respective priority indicators for the two uplink channels and comparing the priority indicators. UE 115-c may identify the priority indicator based on receiving DCI associated with two uplink channels (e.g., an uplink grant for uplink transmission on one of the uplink channels, and a downlink grant for downlink transmission, wherein a UCI including an acknowledgment feedback message corresponding to the downlink transmission is to be sent on the other uplink channel). In some examples, UE 115-c may determine that the first uplink channel has a higher priority than the second uplink channel based on timing. UE 115-c may determine that the first symbol period of the first uplink channel is first in time. In such examples, determining that the first uplink channel has a first priority level and the second uplink channel has a second priority level is based on determining that the first symbol period of the first uplink channel is first in time, and the second priority level is a lower priority than the first priority level. The first uplink channel may be a PUCCH and the second uplink channel may be a PUSCH, or the first uplink channel may be a PUSCH and the second uplink channel may be a PUCCH.

[0153] Figure 8 An example of a process flow 800 for supporting UCI multiplexing rule simplification for reduced capability UEs according to aspects of the present disclosure is shown. In some examples, the process flow 800 can implement aspects of the wireless communication system 100. The process flow 800 can include a UE 115-d and a base station 105-c, which can be referenced Figure 1 and Figure 2 Examples of corresponding devices described.

[0154] At 805, the base station 105-c may send downlink data on the PDSCH to the UE 115-d.

[0155] The base station 105 - c may send a DCI at 810. The DCI may indicate a grant of resources for uplink data transmission on an uplink shared channel (eg, PDSCH) for the second CC that at least partially overlaps an uplink control channel for UCI on the first CC.

[0156] At 815, UE 115-d may identify that it is a first type of UE (e.g., a RedCap UE). The RedCap UE may be associated with a first multiplexing process performed at 820 and 825, while other UEs 115 (e.g., standard UEs) may be associated with another multiplexing process that includes multiplexing UCI and uplink data transmission.

[0157] At 820, based on its status as a UE RedCap and the overlap between PUSCH and PUCCH on different CCs, UE 115-d may send UCI on the first CC, and at 825, UE 115-d may send an uplink data transmission to the second CC. That is, UE 115 may avoid multiplexing UCI and uplink data on the first CC, the second CC, or both based on being a RedCap UE.

[0158] If the second PUCCH overlaps with uplink data transmission on the second CC, UE 115 - a may multiplex the second UCI and the uplink data transmission on the second CC at 825 .

[0159] At another point in time, if PUSCH and PUCCH overlap on the same CC, UE 115-d may multiplex UCI and data. For example, if PUCCH and PUSCH overlap on the first CC at another point in time, UE 115-d may multiplex UCI and uplink data on the first CC.
