Technical Field

[0002] The following relates to wireless communications, including multiplexing high priority and low priority uplink control information (UCI) on a physical uplink control channel (PUCCH). Background Art

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of these multiple access systems include fourth generation (4G) systems such as long term evolution (LTE) systems, advanced 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 employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread spectrum 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 for multiple communication devices, which may also be referred to as user equipment (UE). Summary of the Invention

[0004] Various aspects of the described techniques involve configuring a communications device (which may be a UE) to separately encode low-priority UCI and high-priority UCI, and multiplexing the encoded low-priority UCI and the encoded high-priority UCI on the same physical uplink channel (e.g., a physical uplink control channel (PUCCH)). The UE may be configured with multiple coding rates, from which the UE may select based on, for example, a payload size (e.g., number of bits) associated with the low-priority UCI and a payload size (e.g., number of bits) associated with the high-priority UCI. In some examples, the payload size associated with the low-priority UCI and the payload size associated with the high-priority UCI may be the same or different. Alternatively, the UE may be configured with a separate set of coding rates for low-priority UCI and a separate set of coding rates for high-priority UCI. The UE may multiplex the low-priority UCI and the high-priority UCI by mapping them to physical uplink channel resources in a sequential manner (e.g., mapping the high-priority UCI followed by the low-priority UCI). Thus, the UE can be configured to support improved transmission of UCI by separately encoding and multiplexing UCI with different priorities. The described techniques can also provide improvements in power consumption and, in some examples, can promote increased efficiency for high reliability and low latency uplink operation, among other benefits.

[0049] A wireless communication system may include various communication devices such as user equipment (UE) and base stations, wherein the base stations may provide wireless communication services to the UE. For example, such a base station may be a next-generation Node B (referred to as a gNB), which may support multiple radio access technologies including 4G systems (e.g., 4G LTE) and 5G systems (which may be referred to as 5G NR). In a wireless communication system, the UE may send uplink messages carrying uplink control information (UCI) to support various uplink operations. For example, in some examples, the UCI may convey various information, including feedback information (e.g., hybrid automatic repeat request acknowledgment (HARQ-ACK), scheduling information (e.g., scheduling request (SR)), or channel information (e.g., channel state information (CSI)), in any combination. In some cases, different UCIs may have different priorities (e.g., a first UCI may have a higher priority and a second UCI may have a lower priority).

[0050] The UE may encode one or more UCIs and transmit the one or more UCIs on a physical uplink channel, such as a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH). In some cases, the UE may multiplex high-priority UCI and low-priority UCI on the same physical uplink channel (e.g., PUCCH). In a wireless communication system, the UE may experience interference, which may affect the transmission of UCI. In some cases, when encountering interference with high-priority UCI (e.g., carried on the PUSCH), the UE may discard low-priority UCI. As a result, the UE may have to retransmit at least some UCI, which may result in increased latency and power consumption, among other disadvantages. Therefore, it may be desirable to better protect high-priority UCI compared to low-priority UCI while avoiding discarding low-priority UCI. As described herein, in some examples, various wireless communication systems and devices may implement two levels of priority (e.g., high priority and low priority), or in some examples, more than two levels of priority (e.g., highest priority, medium priority, and lowest priority), among other examples.

[0051] To address the above shortcomings, various aspects of the present disclosure relate to configuring the UE to encode low-priority UCI and high-priority UCI separately. In addition, the UE can be configured to multiplex the encoded low-priority UCI and the encoded high-priority UCI on the same physical uplink channel (e.g., PUCCH). The UE can encode the low-priority UCI and the high-priority UCI separately using different coding rates. Alternatively, the UE can encode the low-priority UCI and the high-priority UCI separately using the same coding rate. In some examples, the UE can be configured with multiple coding rates, and the UE can select from these multiple coding rates based on, for example, the payload size associated with the low-priority UCI and the payload size associated with the high-priority UCI. Alternatively, the UE can be configured with a set of separate coding rates for low-priority UCI and a set of separate coding rates for high-priority UCI.

[0052] For example, when the payload size is, for example, less than or equal to 2 bits, the UE may encode the low-priority UCI and the high-priority UCI using a specific coding rate (e.g., a first coding rate). In some other examples, when the payload size is, for example, between 2 bits and 11 bits, the UE may encode the low-priority UCI and the high-priority UCI using a specific coding rate (e.g., a second coding rate). In other examples, when the payload size is, for example, greater than 11 bits, the UE may encode the low-priority UCI and the high-priority UCI using a specific coding rate (e.g., a third coding rate). Additionally or alternatively, when the payload size is, for example, less than or equal to 11 bits, or greater than 11 bits, the UE encodes the low-priority UCI and the high-priority UCI using a specific coding rate (e.g., a fourth or fifth coding rate).

[0053] The UE may multiplex low-priority UCI and high-priority UCI by mapping them to physical uplink channel resources (e.g., PUCCH resources) based on an order. For example, the UE may map high-priority UCI to the corresponding resources and then map low-priority UCI to the corresponding resources. The UE may also determine the physical uplink channel resources to be used by different types of UCI. In some examples, the UE may map a first type of UCI with a higher priority (e.g., HARQ-ACK, SR, CSI part 1) and then map a first type of UCI with a lower priority (e.g., HARQ-ACK, SR, CSI part 1). Additionally or alternatively, the UE may map a second type of UCI with a higher priority (e.g., CSI part 2) and then map a second type of UCI with a lower priority (e.g., CSI part 2). In some other examples, the UE may map a first type of UCI with a higher priority (e.g., HARQ-ACK, SR, CSI part 1), then map a second type of UCI with a higher priority (e.g., CSI part 2), then map a first type of UCI with a lower priority (e.g., HARQ-ACK, SR, CSI part 1) and a second type of UCI with a lower priority (e.g., CSI part 2). In addition, when the UE maps low-priority UCI and high-priority UCI, the UE may map the high-priority UCI closer to the demodulation reference signal (DMRS) resource than the low-priority UCI.

[0054] Various aspects of the present disclosure may be implemented to achieve one or more of the following potential advantages or improvements. The present disclosure may provide benefits and enhancements to the operation of a UE. For example, operations performed by the UE may provide improvements to UCI transmission. By configuring the UE to encode low priority UCI and high priority UCI separately, the UE may avoid retransmission of some UCI because the low priority UCI and high priority UCI are protected separately. In some examples, configuring the UE to support multiplexing of separately encoded low priority UCI and high priority UCI may support improvements in power saving of the UE. For example, the UE may increase its battery life by providing efficient uplink transmission of UCI in a wireless communication system.

[0055] Aspects of the present disclosure are first described in the context of a wireless communication system.Aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow charts related to multiplexing high-priority and low-priority UCI on a PUCCH.

[0056] Figure 1An example of a wireless communication system 100 that supports multiplexing high-priority and low-priority UCI on a PUCCH according to 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 Advanced 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, communication with low-cost and low-complexity devices, or any combination thereof.

[0057] Base stations 105 may be dispersed throughout a geographic area to form wireless communication system 100 and may be devices of varying forms or 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 over which UEs 115 and base station 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographic area over which base stations 105 and UEs 115 may support communication of signals according to one or more radio access technologies.

[0058] 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 1 Some example UEs 115 are shown in FIG. 1 . The UEs 115 described herein may be able to communicate with various types of devices (e.g., other UEs 115, base stations 105, or network devices (e.g., core network nodes, relays, integrated access and backhaul (IAB) nodes, or other network devices), such as Figure 1 as shown) for communication.

[0059] The base stations 105 may communicate with the core network 130, with each other, or both. For example, the base stations 105 may interface with 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) or indirectly (e.g., via the core network 130), or both directly and indirectly, over the backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, the backhaul links 120 may be or include one or more wireless links. The one or more base stations 105 described herein may include or may be referred to by one of ordinary skill in the art as a base transceiver, a radio base station, an access point, a radio transceiver, a Node B, an eNodeB (eNB), a next generation Node B, or a Giga Node B (any of which may be referred to as a gNB), a Home NodeB, a Home eNodeB, or other appropriate terminology.

[0060] The UE 115 may include or be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscription device, or some other suitable term, where "device" may also be referred to as a unit, a station, a terminal, or a client, etc. The UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet, a laptop, or a personal computer. In some examples, the UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as home appliances, or vehicles, meters, etc. The UE 115 described herein is capable of communicating with various types of devices, such as other UEs 115 that may sometimes act as repeaters, as well as base stations 105 and network devices (including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations), etc., such as Figure 1 shown.

[0061] The UE 115 and the 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 collection of radio spectrum resources with a defined physical layer structure for supporting the communication link 125. For example, a carrier used for the communication link 125 can include a portion of a radio spectrum band (e.g., a bandwidth part (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A Pro, NR). Each physical layer channel can carry acquisition signaling (e.g., synchronization signals, system information), control signaling to coordinate operation for the carrier, user data, or other signaling. The wireless communication system 100 can support communication with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0062] The carrier may also have acquisition signaling or control signaling for coordinating the operation of 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 located based on a channel raster for UE 115 discovery. A carrier may operate in a standalone mode, where a UE 115 may perform initial acquisition and connection via the carrier, or 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. 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 downlink and uplink communications (e.g., in TDD mode).

[0063] A carrier can be associated with a particular bandwidth of radio spectrum, and in some examples, the carrier bandwidth can be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth can be one of a plurality of determined bandwidths of a carrier for 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) can have a hardware configuration that supports communication on a particular carrier bandwidth, or can be configured to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 can include a base station 105 or a 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, a BWP) or all of the carrier bandwidth.

[0064] The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using a multicarrier modulation (MCM) technique 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 be composed of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and 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 may be. Wireless communication resources may refer to a combination of radio 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 communications with the UE 115.

[0065] One or more numerologies may be supported for a carrier, where the numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, 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 restricted to the one or more active BWPs. Time intervals for a base station 105 or a UE 115 may be expressed in multiples of a basic time unit, which may be, for example, T s =1 / (Δf max ·N f ) seconds sampling period, where Δf maxIt can represent the maximum subcarrier spacing supported, and N f The maximum supported discrete Fourier transform (DFT) size may be indicated. Time intervals for 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).

[0066] Each frame can include multiple consecutively numbered subframes or time slots, and each subframe or time slot can have the same duration. In some examples, a frame can be divided into multiple subframes (e.g., in the time domain), and each subframe can be further divided into multiple time slots. Alternatively, each frame can include a variable number of time slots, and the number of time slots can depend on the subcarrier spacing. Each time slot can include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix that precedes each symbol period). In some wireless communication systems 100, the time slot can be further divided into multiple mini-time slots that contain one or more symbols. In addition to the cyclic prefix, each symbol period can contain one or more (e.g., N f ) sampling period. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation. A subframe, slot, minislot, or symbol may be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) 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 a burst of a shortened TTI (sTTI)).

[0067] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, for example, using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a number of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of UEs 115 may monitor or search a 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 in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coding 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 .

[0068] 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., via a carrier), and can be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), etc.) used to distinguish 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 the logical communication entity operates. Depending on various factors (e.g., the capabilities of the base station 105), 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 the geographic coverage area 110, etc.

[0069] A macro cell typically covers a relatively large geographic area (e.g., a radius of several kilometers) and allows unrestricted access to UEs 115 that have a service subscription with a network provider that supports the macro cell. Compared to a macro cell, a small cell can be associated with a low-power base station 105, and the small cell can operate in the same or different frequency bands (e.g., licensed or unlicensed) as the macro cell. A small cell can provide unrestricted access to UEs 115 that have a service subscription with the network provider, or can provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG) or UEs 115 associated with users in a home or office). A 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. In some examples, a carrier can support multiple cells, and different cells can be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)), which can provide access to different types of devices.

[0070] In some examples, base stations 105 can 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 can overlap, but the different geographic coverage areas 110 can be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies can be supported by different base stations 105. The wireless communication system 100 can include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0071] Some UEs 115, such as 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 technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices with integrated sensors or meters that measure or capture information and relay that information to a central server or application that can utilize or present the information to a person 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, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based service billing.

[0072] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports one-way communication for either transmission or reception, but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for the UE 115 include entering a power saving deep sleep mode when not engaged in active communications, operating over a limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 may 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 guard band of a carrier, or outside a carrier.

[0073] 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. UE 115 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.

[0074] UE 115 may also be able to communicate directly with other UEs 115 via device-to-device (D2D) communication links 135 (e.g., using a point-to-point (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UEs 115 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, a group of UEs 115 communicating via D2D communication may employ a one-to-many (1:M) system, wherein each UE 115 transmits to each 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 UEs 115 without involving base station 105.

[0075] The D2D communication link 135 can be an example of a communication channel (e.g., a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination thereof. The vehicles can signal 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 (e.g., roadside units) or communicate with a network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or both.

[0076] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), a user plane function (UPF)) that routes packets or interconnections to external networks. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be transmitted via the user plane entity, which may provide IP address allocation and other functions. The user plane entity may connect to IP services 150 of one or more network operators. The IP services 150 may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or packet-switched streaming services.

[0077] Some 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 consolidated into a single network device (e.g., base station 105).

[0078] The wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Often, 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 long. UHF waves may be blocked or redirected by buildings and environmental features, but the waves may be sufficient to penetrate structures to enable a macrocell to provide service to a UE 115 located indoors. Transmissions using UHF waves can be associated with smaller antennas and shorter distances (e.g., less than 100 km) compared to transmissions using the smaller frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0079] The wireless communication system 100 can also operate in the super high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also known as the centimeter band), or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz), which is also known as the millimeter band. In some examples, the wireless communication system 100 can support millimeter wave (mmW) communications between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices can be even smaller and more compact than the UHF antennas. In some examples, this can facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may suffer from greater atmospheric attenuation and shorter transmission distances than SHF or UHF transmissions. The techniques disclosed herein can be employed in transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may differ depending on the country or regulatory body.

[0080] The wireless communication system 100 can use licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 can adopt licensed 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 the base station 105 and the UE 115 can use carrier sensing for conflict detection and avoidance. In some examples, the operation in the unlicensed band can be based on a carrier aggregation configuration combined with component carriers operating in a licensed band (e.g., LAA). The operation in the unlicensed spectrum can include downlink transmission, uplink transmission, P2P transmission or D2D transmission, etc.

[0081] A base station 105 or a UE 115 may be equipped with multiple antennas that may be used to employ techniques such as transmit diversity, receive diversity, multiple-input, multiple-output (MIMO) communications, or beamforming. The antennas of a base station 105 or a UE 115 may be located within one or more antenna arrays or antenna panels that 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 a base station 105 may be located at different geographic locations. The base station 105 may have an antenna array having a number of rows and columns of antenna ports that the base station 105 may use to support beamforming for communicating 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 panels may support radio frequency beamforming for signals transmitted via the antenna ports.

[0082] The base station 105 or UE 115 can use MIMO communication to take advantage of multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. For example, multiple signals may be sent by a transmitting device via different antennas or different antenna combinations. Similarly, a receiving device may receive multiple signals via different antennas or different antenna combinations. 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 techniques include single-user MIMO (SU-MIMO), in which multiple spatial layers are sent to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are sent to multiple devices.

[0083] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105 or a UE 115) to shape or steer an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating in a particular direction 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, a phase shift, or both to signals carried via antenna elements associated with the device. The adjustments associated with each antenna element may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0084] The base station 105 or the UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the base station 105 in different directions. For example, the 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 to identify (e.g., by a transmitting device (such as the base station 105) or by a receiving device (such as the UE 115)) the beam direction for later transmission or reception by the base station 105.

[0085] Some signals, such as data signals associated with a particular receiving device, may be transmitted by base station 105 in a single beam direction, e.g., a direction associated with a receiving device, such as UE 115. In some examples, a beam direction associated with a 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 of a plurality of signals transmitted in different directions by base station 105 and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or otherwise with an acceptable signal quality.

[0086] In some examples, transmission 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 use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from the base station 105 to the UE 115). The UE 115 may report feedback indicating precoding weights used for one or more beam directions, and the feedback may correspond to the configured number of beams across the system bandwidth or one or more subbands. The base station 105 may send a reference signal (e.g., a cell-specific reference signal (CRS), a CSI reference signal (CSI-RS)), which may be precoded or unprecoded. 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 codebook, a linear combination type codebook, a port selection type 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 for sending signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by UE 115) or for sending signals in a single direction (e.g., for sending data to a receiving device).

[0087] When receiving various signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) from the base station 105, a 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, processing the received signal according to different antenna subarrays, receiving according to different receive beamforming weight sets applied to the received signal at multiple antenna elements of the antenna array (e.g., different directional listening weight sets), or processing the received signal according to different receive beamforming weight sets applied to the received signal at multiple antenna elements of the antenna array, any of which can 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, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0088] The wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly to communicate over logical channels. The media access control (MAC) layer can perform priority processing and multiplexing of logical channels into transport channels. The MAC layer can also use error detection technology, error correction technology, or both to support retransmission 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 an RRC connection between the UE 115 and the base station 105 or the core network 130 supporting the radio bearer for user plane data. At the physical layer, transport channels can be mapped to physical channels.

[0089] UE 115 and base station 105 can support retransmission of data to increase the likelihood of successfully receiving the data. HARQ feedback is a technique for increasing the likelihood of correctly receiving data over communication link 125. HARQ can include a combination of error correction (e.g., using a 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-to-noise ratio conditions). In some examples, a device can support same-slot HARQ feedback, wherein the device can provide HARQ feedback in a particular time slot for data received in previous symbols of the time slot. In other cases, the device can provide HARQ feedback in subsequent time slots, or according to some other time interval.

[0090] In the wireless communication system 100, the UE 115 may send control information and data to the base station 105 or other UEs 115. For example, the UE 115 may send one or more UCIs on the PUCCH and uplink data on the PUSCH. The UCI may convey information including channel information, feedback information, or scheduling information, or a combination thereof. The channel information may be CSI, which may include a channel quality indicator (CQI), a precoding matrix indicator (PMI), or a rank indicator (RI), or a combination thereof. The feedback information may include an acknowledgement (ACK), a negative acknowledgement (NACK), or HARQ feedback (e.g., HARQ-ACK). The scheduling information may include an uplink SR.

[0091] The UE 115 may encode and multiplex the UCI and transmit the UCI on a physical uplink channel (e.g., PUCCH or PUSCH). The UE 115 may jointly encode UCI such as HARQ-ACK, SR, or CSI part 1. The UE 115 may encode CSI part 2 separately from other UCI (e.g., HARQ-ACK, SR, or CSI part 1) because the payload size of CSI part 2 may depend on the payload size of CSI part 1. The UE 115 may encode the UCI including HARQ-ACK, SR, CSI part 1, and CSI part 2 using the same coding rate. Different UCI may also have different priorities (e.g., higher priority, lower priority). Thus, the UE 115 may encode high-priority UCI and low-priority UCI using different coding rates or the same coding rate, as described herein.

[0092] The UE 115 may multiplex high-priority UCI and low-priority UCI on the same physical uplink channel (e.g., PUCCH). The PUCCH may be associated with a PUCCH format. The UE 115 may be configured to use different PUCCH formats for different payload sizes carrying UCI bits. In some examples, the UE 115 may use PUCCH format 0 or PUCCH format 1 based on a payload size of 1 or 2 bits. In some other examples, the UE 115 may use PUCCH format 2, PUCCH format 3, or PUCCH format 4 based on a payload size greater than 2 bits. Thus, the UE 115 may determine and select a PUCCH format based on the total number of UCI bits. The UE 115 may determine the total number of resource blocks available for uplink transmission of UCI, for example, on a PUCCH with a particular PUCCH format (e.g., PUCCH format 2 or PUCCH format 3) based on the total UCI payload or the coding rate (e.g., a given coding rate or a maximum coding rate), or both. UE 115 may determine the total number of resource blocks available for uplink transmission of UCI, for example, according to equation (1): in, represents the total number of available resource elements per resource block (e.g., over all configured time resources (e.g., Orthogonal Frequency Division Multiplexing (OFDM) symbols)), R represents the coding rate, and Q m represents the modulation order, and K represents the number of UCI bits.

[0093] Various aspects of the present disclosure relate to configuring the UE 115 to encode low-priority UCI and high-priority UCI separately. A PUSCH or PUCCH transmission including repetitions (if any) may correspond to priority index 0 or priority index 1. In some examples, low-priority UCI may correspond to priority index 0, while high-priority UCI may correspond to priority index 1. In some examples, for configured granted PUSCH transmissions, the UE 115 may determine the priority index based on priority information (if provided). For PUCCH transmissions with HARQ-ACK information corresponding to semi-persistent scheduling (SPS) PDSCH reception or SPS PDSCH release, the UE 115 may determine the priority index based on preconfigured parameters (if provided). For PUCCH transmissions with SR, the UE 115 may determine the corresponding priority based on preconfigured parameters. For PUSCH transmissions with semi-persistent CSI reporting, the UE 115 may determine the priority index based on the priority indicator field (if provided) in DCI format 0_1 or DCI format 0_2 that activates semi-persistent CSI reporting. If no priority index is provided to UE 115 for PUSCH or PUCCH transmission, the priority index may be 0.

[0094] In addition, UE 115 can be configured to multiplex the encoded low-priority UCI and the encoded high-priority UCI on the same physical uplink channel (e.g., PUCCH). UE 115 can encode the low-priority UCI and the high-priority UCI separately using different coding rates. Alternatively, UE 115 can encode the low-priority UCI and the high-priority UCI separately using the same coding rate. In some examples, the UE can be configured with multiple coding rates, and UE 115 can select from these multiple coding rates based on, for example, the payload size associated with each of the low-priority UCI and the high-priority UCI, as described herein. Alternatively, UE 115 can be configured with a set of separate coding rates for low-priority UCI and a set of separate coding rates for high-priority UCI.

[0095] Thus, UE 115 may determine the total number of resource blocks available for uplink transmission of low-priority UCI and high-priority UCI, for example, according to equation (2): in, represents the total number of available resource elements per resource block (e.g., over all configured time resources (e.g., OFDM symbols)), R1 represents the corresponding coding rate for low-priority UCI, R2 represents the corresponding coding rate for high-priority UCI, and Qm Denotes the modulation order, K1 denotes the number of UCI bits used for lower-priority UCI, and K2 denotes the number of UCI bits used for higher-priority UCI. Thus, UE 115 can be configured to support improvements in UCI transmission by separately encoding and multiplexing UCI with different priorities. UE 115 can also achieve improved power savings and, in some examples, facilitate enhanced efficiency for higher reliability and lower latency UCI transmission, among other benefits.

[0096] Figure 2 An example of a wireless communication system 200 is shown that supports multiplexing high priority and low priority UCI on a PUCCH according to aspects of the present disclosure. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100 or can be implemented by aspects of the wireless communication system 100. For example, the wireless communication system 200 can include a base station 105 and a UE 115 within a geographic coverage area 110. The base station 105 and the UE 115 can be referenced to Figure 1 Examples of corresponding devices described herein. In some examples, the wireless communication system 200 can support multiple radio access technologies, including 4G systems such as LTE systems, LTE-A systems, or LTE-A Pro systems, and 5G systems, which can be referred to as NR systems. The wireless communication system 200 can support improvements in power consumption, spectral efficiency, higher data rates, and in some examples, can promote increased efficiency of UCI operations with higher reliability and lower latency, among other benefits.

[0097] Base stations 105 and UEs 115 may be configured with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming, or any combination thereof. The antennas of base stations 105 and UEs 115 may be located within one or more antenna arrays or antenna panels that can support multiple-input multiple-output (MIMO) operations or transmit or receive beamforming. For example, base station 105 antennas or antenna arrays may be co-located at an antenna assembly (e.g., an antenna tower). In some examples, antennas or antenna arrays associated with base stations 105 may be located at different geographic locations. Base stations 105 may have antenna arrays that include multiple rows and columns of antenna ports that base stations 105 may use to support beamforming for communications with UEs 115. Similarly, UEs 115 may have one or more antenna arrays capable of supporting various multiple-input multiple-output (MIMO) or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via one or more antenna ports. Thus, base stations 105 and UEs 115 may be configured to support directional communications using multiple antennas.

[0098] In the wireless communication system 200, the UE 115 may support operations to preserve resources (e.g., time and frequency resources of the wireless communication system 200) or battery life of the UE 115, among other examples. In some examples, the UE 115 may be configured to support UCI operations to manage or improve directional communication between the base station 105 and the UE 115. For example, the UE 115 may send uplink messages carrying UCI to support various uplink operations. For example, the UCI may convey various information, including feedback information (e.g., HARQ-ACK), scheduling information (e.g., SR), or channel information (e.g., CSI) for managing or improving directional communication between the base station 105 and the UE 115, or any combination thereof. In some cases, different UCIs may have different priorities (e.g., a first UCI may have a higher priority and a second UCI may have a second, lower priority).

[0099] UE 115 may encode UCI and transmit it on a physical uplink channel, such as PUCCH 205 or PUSCH. In some cases, UE 115 may multiplex high-priority UCI 210 and low-priority UCI 215 on the same physical uplink channel (e.g., PUCCH 205). In wireless communication system 200, UE 115 may experience interference, which may affect the transmission of UCI. In some cases, because UE 115 may not be able to transmit two uplink transmissions (e.g., both low-priority UCI and high-priority UCI) simultaneously, UE 115 may discard low-priority UCI. As a result, UE 115 may have to retransmit at least some UCI, which may result in increased latency and power consumption, among other drawbacks. Therefore, it may be desirable to better protect high-priority UCI compared to low-priority UCI, while avoiding discarding low-priority UCI.

[0100] The UE 115 may be configured to separately encode the high-priority UCI 210 and the low-priority UCI 215. Furthermore, the UE 115 may be configured to multiplex the encoded high-priority UCI 210 and the encoded low-priority UCI 215 on the same physical uplink channel (e.g., PUCCH 205). The UE 115 may separately encode the high-priority UCI 210 and the low-priority UCI 215 using different coding rates. Alternatively, the UE 115 may separately encode the high-priority UCI 210 and the low-priority UCI 215 using the same coding rate. In some examples, the UE 115 may be configured with multiple coding rates (e.g., via an RRC configuration message), from which the UE 115 may select, for example, based on the payload size associated with each of the high-priority UCI 210 and the low-priority UCI 215. Alternatively, the UE 115 may be configured with a separate set of coding rates for high priority UCI 210 and a separate set of coding rates for low priority UCI 215 .

[0101] The base station 105 may configure multiple coding rates for the UE 115 to use, for example, for one or more PUCCH resources associated with the PUCCH 205. In some examples, the base station 105 may configure multiple coding rates based on the PUCCH 205 being associated with a specific PUCCH format (e.g., PUCCH format 2 or PUCCH format 3). For example, when the payload size is, for example, less than or equal to 2 bits (UCI bits ≤ 2 bits), the UE 115 may use a specific coding rate (e.g., the first coding rate) to encode the high-priority UCI 210 and the low-priority UCI 215. In some other examples, when the payload size is, for example, between 2 and 11 bits (2 bits ≤ UCI bits ≤ 11 bits), the UE 115 may use a specific coding rate (e.g., the second coding rate) to encode the high-priority UCI 210 and the low-priority UCI 215. In other examples, when the payload size is, for example, greater than 11 bits (UCI bits > 11 bits), the UE 115 may use a specific coding rate (e.g., the third coding rate) to encode the high-priority UCI 210 and the low-priority UCI 215. Additionally or alternatively, when the payload size is, for example, less than or equal to 11 bits (UCI bits ≤ 11 bits) or greater than 11 bits (UCI bits > 11 bits), the UE 115 may use a specific coding rate (e.g., the fourth or fifth coding rate) to encode the high-priority UCI 210 and the low-priority UCI 215. In some examples, the UCI including HARQ-ACK, SR, CSI part 1, and CSI part 2 with the same priority (e.g., low priority or high priority) and the same payload range (e.g., 2 bits < K ≤ 11 bits, or K > 11 bits, or K > 2 bits) may be encoded with different coding rates.

[0102] The base station 105 may configure at least two sets of coding rates, one set for high-priority UCI 210 and a second set for low-priority UCI 215. Each of these sets may include one or more of the example coding rates. In some examples, the base station 105 may configure two coding rates for a given priority level (e.g., high priority, low priority) or across two priority levels (e.g., high priority and low priority). For example, when the payload size is, for example, less than or equal to 2 bits (UCI bits ≤ 2 bits), the UE 115 may encode the high-priority UCI 210, the low-priority UCI 215, or both using a specific coding rate (e.g., a first coding rate). When the payload size is, for example, greater than 2 bits (UCI bits > 2 bits), the UE 115 may encode the high-priority UCI 210 and the low-priority UCI 215 using a specific coding rate (e.g., a second coding rate), where the UCI bits include all available UCIs of the same priority level.

[0103] The base station 105 may configure one or more of the above exemplary coding rates for PUCCH resources used to transmit the multiplexed high-priority UCI 210 and low-priority UCI 215. For example, the base station 105 may configure two sets of coding rates for the PUCCH resources, and the UE 115 may use the PUCCH resources to transmit the multiplexed high-priority UCI 210 and low-priority UCI 215 (e.g., multiplexed high-priority HARQ-ACK and low-priority HARQ-ACK). For the high-priority PUCCH resources, one or more of the above exemplary coding rates for the high-priority UCI 210 may be configured, and for the low-priority PUCCH resources, one or more of the above exemplary coding rates for the low-priority UCI 215 may be configured. The UE 115 may determine one or more of the above exemplary coding rates for the high-priority UCI 210 and the low-priority UCI 215 based on the corresponding PUCCH resources scheduled to transmit the high-priority UCI 210 and the low-priority UCI 215, respectively.

[0104] In some examples, if high-priority UCI 210 is scheduled on a first PUCCH resource and low-priority UCI 215 is scheduled on a second PUCCH resource, and the first and second PUCCH resources overlap in the time domain (e.g., symbol, time slot, etc.), UE 115 may multiplex high-priority UCI 210 and low-priority UCI 215 on a third PUCCH resource. The third PUCCH resource may be one of the first PUCCH resource or the second PUCCH resource. Alternatively, the third PUCCH resource may be a resource different from the first and second PUCCH resources. UE 115 may determine the coding rates for high-priority UCI 210 and low-priority UCI 215 based on the coding rates configured for the first and second PUCCH resources, respectively. In this way, base station 105 does not need to configure two sets of coding rates for a single PUCCH resource.

[0105] The PUCCH 205 may be associated with a particular PUCCH format (e.g., PUCCH format 2, PUCCH format 3, or PUCCH format 4). In some examples, as described herein, if the total number of UCI bits associated with the high-priority UCI 210 or the low-priority UCI 215, or both, is greater than two bits, the UE 115 may transmit the multiplexed UCI payload on a PUCCH having PUCCH format 2, PUCCH format 3, or PUCCH format 4. In some examples, based on the respective UCI payloads and the configured coding rate, the UE 115 may determine the number of resources to use for the high-priority UCI 210 and the low-priority UCI 215, and then determine the total number of resource blocks based on the total number of resources used for the high-priority UCI 210 and the low-priority UCI 215. The UE 115 may multiplex the high-priority UCI 210 and the low-priority UCI 215 by mapping them to physical uplink channel resources (e.g., PUCCH resources) based on an order. When the UE 115 maps the high priority UCI 210 and the low priority UCI 215, the UE 115 may map the high priority UCI 210 closer to the DMRS resource than the low priority UCI 215, such as Figure 3A and Figure 3B Described in more detail in .

[0106] For example, UE 115 may map high priority UCI 210 to corresponding resources and then map low priority UCI 215 to corresponding resources. UE 115 may also determine the physical uplink channel resources to be used by different types of UCI. In some examples, UE 115 may map a first type of UCI with high priority (e.g., HARQ-ACK, SR, CSI part 1) and then map a second type of UCI with low priority (e.g., HARQ-ACK, SR, and CSI part 1). Additionally or alternatively, UE 115 may map a third type of UCI with high priority (e.g., CSI part 2) and then map a fourth type of UCI with low priority (e.g., CSI part 2). Thus, the mapping order may be: (1) high priority HARQ-ACK, SR, and CSI part 1; (2) low priority HARQ-ACK, SR, and CSI part 1; (3) high priority CSI part 2; and (4) low priority CSI part 2. In some other examples, UE 115 may map a first type of UCI with high priority (e.g., HARQ-ACK, SR, CSI part 1), then map a third type of UCI with high priority (e.g., CSI part 2), then map a second type of UCI with low priority (e.g., HARQ-ACK, SR, CSI part 1), and then map a fourth type of UCI with low priority (e.g., CSI part 2). Thus, the mapping order may be: (1) high priority HARQ-ACK, SR, and CSI part 1; (3) high priority CSI part 2; (2) low priority HARQ-ACK, SR, and CSI part 1; and (4) low priority CSI part 2.

[0107] The exemplary multiplexing order above means that when the total number of resources on the PUCCH 205 is limited (e.g., the total number of resources on the PUCCH 205 is less than the total number of resources required to transmit the multiplexed high priority UCI 210 and low priority UCI 215), the UE 115 may drop one or more UCI types starting from the last UCI type in the order until the first UCI type in the order. For example, for a mapping order of (1) high priority HARQ-ACK, SR, and CSI part 1, (2) low priority HARQ-ACK, SR, and CSI part 1, (3) high priority CSI part 2, and (4) low priority CSI part 2, the UE 115 may first drop (4) low priority CSI part 2, then drop (3) high priority CSI part 2, and so on. In another example, for the mapping order of (1) high priority HARQ-ACK, SR and CSI part 1, (3) high priority CSI part 2, (2) low priority HARQ-ACK, SR and CSI part 1, and (4) low priority CSI part 2, UE115 may first discard (4) low priority CSI part 2, then discard (2) low priority HARQ-ACK, SR and CSI part 1, and so on.

[0108] The high-priority UCI 210 or the low-priority UCI 215 may include 1 to 2 UCI bits. In some cases, if the UE 115 is to (e.g., must) multiplex 1 to 2 high-priority UCI bits (e.g., high-priority HARQ-ACK) with one or more low-priority UCI bits (e.g., low-priority UCI including ≥ 1 UCI bit), or if the UE 115 is to (e.g., must) multiplex 1 to 2 low-priority UCI bits (e.g., low-priority HARQ-ACK) with more than one or more high-priority UCI bits (≥ 1 UCI bit), the UE 115 may encode the 1 to 2 UCI bit HARQ-ACK as follows: If only 1 HARQ-ACK bit is sent for a given priority, the UE 115 may repeat the HARQ-ACK bit L times according to the configured coding rate. Otherwise, if two HARQ-ACK bits are sent for a given priority, the UE may encode the two HARQ-ACK bits using a simple code by encoding the two bits [a0, a1] to [a0, a1, a0+a1], and then perform repetition (e.g., continue encoding the two HARQ-ACK bits) until the coding rate reaches the configured value. Here, a0+a1 represents the modulo-2 sum of bits a0 and a1. When multiplexing the two HARQ-ACK bits with other UCI, the UE 115 may apply simple coding to the two HARQ ACK bits on the PUCCH 205. Thus, one or two HARQ-ACK bits associated with a first priority (e.g., high priority) may be multiplexed with UCI of a second priority (e.g., low priority). The UCI of the second priority may be more than two bits, or it may be one or two bits. That is, as long as the total payload of the high priority UCI 210 and the low priority UCI 215 exceeds two bits.

[0109] In the wireless communication system 200, the UE 115 can therefore be configured to support improvements for UCI transmission by separately encoding and multiplexing UCI with different priorities. The UE 115 can also provide improvements in power consumption and, in some examples, can promote increased efficiency for higher reliability and lower latency UCI transmission (e.g., transmission of high priority UCI 210 and low priority UCI 215) in the wireless communication system 200.

[0110] Figure 3A According to aspects of the present disclosure, an example of a resource mapping scheme 300-a that supports multiplexing high priority and low priority UCI on PUCCH is shown. The resource mapping scheme 300-a can be implemented by aspects of wireless communication systems 100 and 200, or can be implemented as described with reference to Figure 1 and Figure 2 Aspects of the wireless communication systems 100 and 200 described herein may be implemented, for example, as described with reference to Figure 1 and Figure 2 The described UE 115 implements the resource mapping scheme 300-a. The resource mapping scheme 300-a may be implemented by the UE 115 to map PUCCH resources to improve efficiency and resource usage of uplink transmissions carrying UCI, and to promote higher reliability of uplink transmissions carrying UCI, among other benefits.

[0111] exist Figure 3A In the example of FIG. 3 , the resource mapping scheme 300 - a can correspond to time resources (e.g., symbol duration, mini-slot duration, slot duration, subframe duration, frame duration) and frequency resources (e.g., subcarriers, carriers) of a physical uplink channel (e.g., PUCCH). UE 115 can use one or more time resources and frequency resources to send control information, data, and other information (e.g., reference signals such as DMRS). Figure 3A , the time resources may include symbol periods 305, 310, 315, 320, 325, and 330 (e.g., OFDM symbols) in the time domain, and the frequency resources may include resource blocks 340 and 345 in the frequency domain. Additionally, the resource mapping scheme 300-a may include, for example, a frequency hop 335 from resource block 340 (e.g., having a first frequency) to resource block 345 (e.g., having a second frequency). In some examples, the UE 115 may uniformly map the coded high-priority UCI or the coded low-priority UCI, or both, to at least some, if not all, of the frequency hops 335. For example, the UE 115 may uniformly map the coded high-priority UCI or the coded low-priority UCI, or both, to at least some, if not all, of the at least two frequency hops (e.g., resource blocks 340, 345) using the same amount of resources, or substantially the same amount of resources, for the first frequency hop (e.g., associated with resource block 340) and the second frequency hop (e.g., associated with resource block 345).

[0112] UE 115 may map the encoded high priority UCI and the encoded low priority UCI to one or more resources according to resource mapping scheme 300-a. In some examples, UE 115 may map the encoded high priority UCI and the encoded low priority UCI based on a rule. For example, the rule may instruct UE 115 that when mapping the encoded high priority UCI and the encoded low priority UCI to physical uplink channel (e.g., PUCCH) resources, UE 115 may map the encoded high priority UCI closer to the DMRS than the encoded low priority UCI. Figure 3A In the example of , frequency hopping 335 may include three symbol periods (e.g., symbol periods 305, 310, and 315, and symbol periods 320, 325, and 330). Each of symbol periods 305 and 320 may carry a DMRS, and the UE 115 may thus map coded high-priority UCI to symbol periods 310 and 325 (e.g., relatively close to the DMRS) and map coded low-priority UCI to one or more remaining available resources (e.g., symbol periods 315 and 330).

[0113] The symbol period 305 carrying the DMRS, the symbol period 310 carrying the coded high-priority UCI, the symbol period 320 carrying the DMRS, and the symbol period 325 carrying the coded high-priority UCI may be contiguous in the time domain, the frequency domain, or both. Alternatively, the symbol period 305 carrying the DMRS, the symbol period 310 carrying the coded high-priority UCI, the symbol period 320 carrying the DMRS, and the symbol period 325 carrying the coded high-priority UCI may not be contiguous in the time domain, the frequency domain, or both. The symbol period 310 carrying the coded high-priority UCI, the symbol period 315 carrying the coded low-priority UCI, the symbol period 325 carrying the coded high-priority UCI, and the symbol 330 carrying the coded low-priority UCI may be contiguous in the time domain, the frequency domain, or both. Alternatively, the symbol period 310 carrying the encoded high priority UCI, the symbol period 315 carrying the encoded low priority UCI, the symbol period 325 carrying the encoded high priority UCI, and the symbol 330 carrying the encoded low priority UCI may not be adjacent in the time domain or the frequency domain or both.

[0114] Figure 3B According to aspects of the present disclosure, an example of a resource mapping scheme 300-a that supports multiplexing high priority and low priority UCI on PUCCH is shown. The resource mapping scheme 300-b can be implemented by aspects of wireless communication systems 100 and 200, or can be implemented as described with reference to Figure 1 and Figure 2 Aspects of the wireless communication systems 100 and 200 described herein may be implemented, for example, as described with reference to Figure 1 and Figure 2 The described UE 115 implements the resource mapping scheme 300-b. The resource mapping scheme 300-b may be implemented by the UE 115 to map PUCCH resources to improve efficiency and resource usage of uplink transmissions carrying UCI, and to promote higher reliability of uplink transmissions carrying UCI, among other benefits.

[0115] exist Figure 3B In the example of FIG. 3 , the resource mapping scheme 300 - b may correspond to time resources (e.g., symbol duration, mini-slot duration, slot duration, subframe duration, frame duration) and frequency resources (e.g., subcarriers, carriers) of a physical uplink channel (e.g., PUCCH). UE 115 may use one or more time resources and frequency resources to transmit control information, data, and other information (e.g., reference signals such as DMRS). Figure 3B , time resources may include symbol periods 350, 355, 360, 365, 370, 375, 380, and 385 (e.g., OFDM symbols) in the time domain, and frequency resources may include resource blocks 390 in the frequency domain. Figure 3B In the example shown, resource mapping scheme 300 - b does not include any frequency hopping.

[0116] UE 115 may map the encoded high priority UCI and the encoded low priority UCI to one or more resources according to resource mapping scheme 300-b. In some examples, UE 115 may map the encoded high priority UCI and the encoded low priority UCI based on a rule. For example, the rule may instruct UE 115 that when mapping the encoded high priority UCI and the encoded low priority UCI to physical uplink channel (e.g., PUCCH) resources, UE 115 may map the encoded high priority UCI closer to the DMRS than the encoded low priority UCI. Figure 3B In the example, each of symbol periods 360 and 375 may carry a DMRS, and UE 115 may thus map the encoded high-priority UCI onto symbol periods 365 and 380 (e.g., relatively proximate to the DMRS) and the encoded low-priority UCI onto one or more of the remaining available resources (e.g., symbol period 370 or 385).

[0117] exist Figure 3BIn the example of FIG. 1 , symbol period 355, symbol period 365, symbol period 370, and symbol period 380 can all be at the same distance from a DMRS symbol (e.g., symbol period 360 or symbol period 375, or both, carrying DMRS). That is, symbol period 355, symbol period 365, symbol period 370, and symbol period 380 are all equally close to the DMRS symbol (distance 1). Symbol period 350 and symbol period 385 can be at a distance of 2 from a DMRS symbol period and further from a DMRS symbol period than symbol period 355, symbol period 365, symbol period 370, and symbol period 380. The distance can be measured by the minimum distance from any DMRS symbol period in the transmission. In some examples, the distance between symbol period 390 (e.g., a data symbol period) and the nearest symbol period carrying DMRS can be 3 (e.g., 3 OFDM symbols). Thus, for example, symbol period 390 is farthest from the DMRS compared to other symbol periods and may be the last symbol period that UE 115 considers when mapping the encoded high-priority UCI (e.g., symbol 390 may be the least preferred symbol period when mapping the encoded high-priority UCI). Therefore, UE 115 may first map the high-priority UCI to symbol period 355, symbol period 365, symbol period 370, and symbol period 380. Additionally or alternatively, if the above mapping is not sufficient, UE 115 may further map the encoded high-priority UCI to symbol period 350 and symbol period 385. Furthermore, if the above mapping is not sufficient, UE 115 may further map the encoded high-priority UCI to symbol period 390. UE 115 may map the low-priority UCI to the remaining resources (e.g., symbol periods) in the PUCCH.

[0118] The symbol period 360 carrying the DMRS, the symbol period 365 carrying the coded high-priority UCI, the symbol period 375 carrying the DMRS, and the symbol period 380 carrying the coded high-priority UCI may be contiguous in the time domain, the frequency domain, or both. Alternatively, the symbol period 360 carrying the DMRS, the symbol period 365 carrying the coded high-priority UCI, the symbol period 375 carrying the DMRS, and the symbol period 380 carrying the coded high-priority UCI may not be contiguous in the time domain, the frequency domain, or both. The symbol period 365 carrying the coded high-priority UCI, the symbol period 370 carrying the coded low-priority UCI, the symbol period 380 carrying the coded high-priority UCI, and the symbol period 385 carrying the coded low-priority UCI may be contiguous in the time domain, the frequency domain, or both. Alternatively, the symbol period 365 carrying the encoded high priority UCI, the symbol period 370 carrying the encoded low priority UCI, the symbol period 380 carrying the encoded high priority UCI, and the symbol period 385 carrying the encoded low priority UCI may be discontinuous in the time domain or the frequency domain or both. Figure 3B In the example of FIG. 3 , the symbol period 370 carrying the encoded low priority UCI and the symbol period 375 carrying the DMRS (eg, the second DMRS) may be consecutive in the time domain or the frequency domain or both.

[0119] Figure 4 According to aspects of the present disclosure, an example of a process flow 400 for supporting multiplexing of high priority and low priority UCI on a PUCCH is shown. The process flow 400 may implement aspects of the wireless communication system 100 and the wireless communication system 200, or may be implemented by referring to each of the respective Figure 1 and Figure 2 The process flow 400 may be implemented based on various aspects of the wireless communication systems 100 and 200 described herein. For example, the process flow 400 may be based on the configuration of the base station 105 or the UE 115 and implemented by the UE 115. The base station 105 and the UE 115 may be examples of base stations and UEs, as described in reference to FIG. Figure 1 and Figure 2 In the following description of process flow 400, operations between base station 105 and UE 115 may be sent in an order different from the example order shown, or operations performed by base station 105 and UE 115 may be performed in a different order or at a different time. Some operations may also be excluded from process flow 400, or other operations may be added to process flow 400.

[0120] At 405, the base station 105 may send a configuration including a set of coding rates for encoding UCI (e.g., one or more UCI bits) to the UE 115. Each coding rate in the set of coding rates may be associated with a first priority (e.g., high priority), or a second priority (e.g., low priority), or a combination thereof. In one example, the base station 105 may send an RRC message, a MAC-CE message, or a downlink control information (DCI) message (or any combination thereof) indicating the configuration. At 410, the UE 115 may encode the high priority UCI using the first coding rate and encode the low priority UCI using the second coding rate. In some examples, as shown in FIG. Figure 2 As described, the coding rate set may include a first coding rate subset for a first priority (e.g., high priority) and a second coding rate subset for a second priority (e.g., low priority). In some examples, the first coding rate subset may be different from the second coding rate subset.

[0121] At 415, UE 115 may multiplex the encoded high priority UCI and the encoded low priority UCI onto the PUCCH. Figure 2 、 Figure 3A and Figure 3B As described, UE 115 may multiplex the coded high priority UCI and the coded low priority UCI onto the PUCCH by mapping the coded high priority UCI and the coded low priority UCI to a set of PUCCH resources. The PUCCH may correspond to one or more PUCCH resources configured with multiple coding rates. In some examples, the PUCCH may correspond to a PUCCH format including PUCCH format 2, PUCCH format 3, or PUCCH format 4. In some examples, as shown in FIG. Figure 2 、 Figure 3A and Figure 3B As described, one or more PUCCH resources associated with the mapped coded high priority UCI and the coded low priority UCI may be continuous in the time domain, or may not be continuous in the time domain. Additionally or alternatively, as described with reference to Figure 2 、 Figure 3A and Figure 3B As described, the one or more PUCCH resources associated with the mapped coded high-priority UCI and the coded low-priority UCI may be contiguous in the frequency domain or non-contiguous in the frequency domain. At 420, UE 115 may transmit the coded high-priority UCI and the coded low-priority UCI to base station 105 via the PUCCH.

[0127] Additionally or alternatively, in some examples, the communication manager 520, the receiver 510, the transmitter 515, or various combinations thereof, or components thereof, may be implemented using code executed by a processor (e.g., such as communication management software or firmware). If implemented using code executed by a processor, the functions of the communication manager 520, the receiver 510, the transmitter 515, or various combinations thereof, or components thereof, may be performed by a general-purpose processor, a DSP, a central processing unit (CPU), an ASIC, an FPGA, or any combination thereof, or other programmable logic device (e.g., a unit configured to or otherwise support the functions described in the present disclosure).

[0239] Although aspects of LTE, LTE-A, LTE-A Pro, or NR systems are described for example purposes, and the terminology of LTE, LTE-A, LTE-A Pro, or NR may be used throughout much of the description, the techniques described herein can be applied beyond LTE, LTE-A, LTE-A Pro, or NR networks. For example, the techniques described may be applicable to various other wireless communication systems, such as Ultra Mobile Broadband (UMB), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, and other systems and radio technologies not explicitly mentioned herein.

[0240] Any of a variety of different technologies and methods may be used to represent the information and signals described herein. For example, the data, instructions, commands, information, signals, bits, symbols, and chips mentioned throughout the foregoing description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

[0241] The various illustrative blocks and components described in conjunction with the present disclosure may be implemented or performed using a general-purpose processor, a DSP, an ASIC, an FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but in the alternative, the processor may be any conventional processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration).

[0242] The functions described herein may be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions may be stored or transmitted as one or more instructions or code on a computer-readable medium. Other examples and implementations are within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functions described herein may be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination of these. Features that implement the functions may also be physically located in multiple locations, including portions that are distributed so that the functions are implemented at different physical locations.

[0243] Computer-readable media include non-transitory computer storage media and communication media, and communication media include any media that helps to transmit a computer program from one place to another. Non-transitory storage media can be any available media that can be accessed by a general-purpose or special-purpose computer. Exemplarily and not restrictively, non-transitory computer-readable media can include RAM, ROM, electrically erasable programmable read-only memory (EEPROM), flash memory, compact disc (CD) ROM or other optical disc storage, magnetic disk storage or other magnetic storage devices or any other non-transitory media that can be used to carry or store required program code modules in the form of instructions or data structures and can be accessed by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. In addition, any connection is appropriately referred to as a computer-readable medium. For example, if a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL) or wireless technologies such as infrared, radio and microwaves are used to transmit software from a website, server or other remote source, then coaxial cable, fiber optic cable, twisted pair, DSL or wireless technologies such as infrared, radio and microwaves are included in the definition of medium. Disk and disc, as used herein, includes CD, laser disc, optical disc, digital versatile disc (DVD), floppy disk, and Blu-ray disc where disks usually reproduce data magnetically, while discs reproduce data optically with lasers.

[0244] As used herein, including in the claims, "or" as used in a list of items (e.g., a list of items ending with a phrase such as "at least one of" or "one or more of") indicates an inclusive list, so that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Moreover, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an exemplary operation described as "based on condition A" can be based on condition A and condition B without departing from the scope of this disclosure. That is, as used herein, the phrase "based on" is to be interpreted in the same manner as the phrase "based at least in part on."

[0245] In the drawings, similar components or features may have the same reference number. In addition, multiple components of the same type may be distinguished by following the reference number with a dash and a second reference number that distinguishes the similar components. If only the first reference number is used in the specification, the description applies to any similar component having the same first reference number, regardless of the second or subsequent reference numbers.

[0246] The descriptions set forth herein in conjunction with the accompanying drawings describe exemplary configurations and do not represent all possible examples that may be implemented or within the scope of the claims. The term "exemplary" as used herein means "serving as an example, instance, or illustration," rather than "preferred" or "superior to other examples." The detailed description includes specific details to provide an understanding of the described technology. However, these technologies can be implemented without these specific details. In some cases, known structures and devices are shown in block diagram form to avoid obscuring the concepts of the described examples.

[0247] The description herein is provided to enable one of ordinary skill in the art to practice or use the present disclosure. Various modifications to the present disclosure will be apparent to those of ordinary skill in the art, and the general principles defined herein may be applied to other variations without departing from the scope of the present disclosure.
