Technical Field

The following relates to wireless communications, including uplink control information multiplexing techniques using multiple repeated uplink communications.

Background

Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems are 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, LTE-advanced (LTE-a) systems, or LTE-a Pro systems, and fifth generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems may employ techniques such as Code Division Multiple Access (CDMA), time Division Multiple Access (TDMA), frequency Division Multiple Access (FDMA), orthogonal FDMA (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 of which simultaneously support communication for multiple communication devices, which may also be referred to as User Equipment (UE).

Some wireless communication systems, such as 4G and 5G systems, may support directional communication using one or more directional beams. Some wireless communication systems, such as 4G and 5G systems, may support repetition of physical channels, such as a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH) or both. As the demands for communication efficiency and reliability increase, efficient techniques for repetition of uplink communication and multiplexing of uplink communication are required.

Detailed Description

A wireless communication system may support communication under a variety of different channel conditions and may select various transmission parameters based on particular channel conditions present between a User Equipment (UE) and a base station or access network entity. In some cases, where the UE has relatively poor channel conditions, one or more communication parameters may be set to help maintain reliable communications under such conditions. In some cases, to help provide reliable communications over relatively poor channels, a base station or access network entity may configure multiple repetitions for certain communications in order to increase the likelihood of successfully receiving the communications. In some cases, for a communication having multiple repetitions, a receiving device may buffer a received signal of a first instance of the communication in a soft buffer and may add a subsequently received signal of a second instance of the communication to the soft buffer. The aggregate buffered signal may then be used to attempt to decode the communication, which may provide a higher likelihood of successful decoding than attempting to decode each repetition individually. This technique may be referred to as soft combining or soft buffering.

In order for the soft combining to provide an aggregate buffered signal across multiple repetitions of the communication, each repetition should have a similar or identical number of coded bits that occupy the resources of the soft buffer so that multiple repetitions can simply be added to the corresponding soft buffer resources. When Uplink Control Information (UCI) is multiplexed with uplink data channel (e.g., physical Uplink Shared Channel (PUSCH)) transmissions, the transmitting UE may determine resources for UCI based at least in part on an offset value (e.g., beta-offset value) that indicates a spectral efficiency ratio of uplink data to UCI. However, in some cases where UCI is multiplexed on multiple uplink data channel (e.g., PUSCH) repetitions, UCI payloads (UCI payload) on different PUSCH repetitions may be different, which may result in different amounts of UCI for different repetitions relative to data channel resources, and which may reduce performance of repeated soft buffering.

For example, when the UE is configured for multiple transmit-receive point (TRP) communication, multiple repetitions may be implemented in which different PUSCH transmission opportunities for the same transport block are transmitted to different TRPs. However, different TRPs may have different channel conditions and different beams, may be configured with different sets of Sounding Reference Signal (SRS) resources, and may have different Channel State Information (CSI) measurement reports. To accommodate different SRS resources and different CSI reports, certain repetitions of PUSCH may have UCI corresponding to a defined beam (e.g., the first/second repetition may include first/second CSI reports, respectively). However, this may result in different repetitions of UCI having different payloads. When determining uplink REs that are to include UCI, the UE uses an offset value that adjusts the number of REs for UCI based on a spectral efficiency ratio between UCI and uplink data transmission, and reusing the same offset for multiple UCI with different payloads may thus result in different spectral efficiencies, which may be undesirable.

In accordance with various techniques discussed herein, multiple repeated transmissions of UCI may be provided in which a spectral efficiency ratio of uplink data to UCI is scaled based at least in part on one or more parameters associated with the multiple repetitions. In some cases, the UE may receive an uplink grant from a base station or access network entity with a set of uplink resources for uplink data transmission, where the uplink data transmission is to be sent in a repetition set and UCI is to be multiplexed with at least some of the repetitions. The uplink grant may provide a set of uplink resources, and the UE may determine a first subset of uplink resources for UCI (e.g., a number of Resource Elements (REs) for UCI) and a second subset of uplink resources for uplink data transmission. The UCI may then be encoded, rate matched, and modulated to generate modulated UCI symbols. The modulated UCI symbols may be mapped to some uplink resources and transmitted with uplink data transmission in other uplink resources. The first subset of uplink resources may be determined based at least in part on a spectral efficiency ratio provided by the base station as an offset value (e.g., beta-offset provided to the UE), and in aspects provided herein, the offset value is scaled based on one or more parameters associated with the plurality of repetitions. The one or more parameters may include, for example, a number of repetitions of uplink data, a number of repetitions of a particular UCI, whether to transmit instances of the repetitions using multiple beams (e.g., in multiple transmit-receive point (TRP) operations that may use multiple sets of Sounding Reference Signal (SRS) resources), a type of UCI, or any combination thereof.

Techniques employed in accordance with various aspects described herein may provide benefits and enhancements to the operation of the system. For example, the described techniques may improve reliability and efficiency of communications by allowing reliable and efficient combining of multiple uplink repetitions, which may increase the likelihood of successfully decoding uplink data and UCI transmitted in the repetition. Such improvements may improve the efficiency of wireless communication at the UE by reducing the delay and reducing the number of retransmissions. In some examples, the described techniques may provide UE determination of a scaling factor for an offset value based on predetermined or configured parameters, which may provide efficient signaling of the offset value according to established signaling (e.g., in Downlink Control Information (DCI) for dynamic beta-offset indication or Radio Resource Control (RRC) signaling for semi-static beta-offset indication), and the UE may scale the indicated offset based on a particular repetition configuration, UCI type, or any combination thereof.

Aspects of the present disclosure are initially described in the context of a wireless communication system. Various examples of multiplexing of UCI repetition of transmission are then discussed. Aspects of the present disclosure are also illustrated and described with reference to process flows, apparatus diagrams, system diagrams, and flowcharts associated with uplink control information multiplexing techniques using multiple repeated uplink communications.

Fig. 1 illustrates an example of a wireless communication system 100 in accordance with aspects of the present disclosure, the wireless communication system 100 supporting uplink control information multiplexing techniques using multiple repeated uplink communications. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an LTE-advanced (LTE-a) network, an LTE-a Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, communications utilizing low cost and low complexity devices, or any combination thereof.

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

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

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

One or more base stations 105 described herein may include or may be referred to by those of ordinary skill in the art as base transceiver stations, radio base stations, access points, radio transceivers, node bs (nodebs), enodebs (enbs), next-generation nodebs or gigabit nodebs (any of which may be referred to as a gNB), home nodebs, home enodebs, or other suitable terminology.

The UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where "device" may also be referred to as a unit, station, terminal, client, or the like. The UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a Personal Digital Assistant (PDA), a multimedia/entertainment device (e.g., a radio, MP3 player, or video device), a camera, a gaming device, a navigation/positioning device (e.g., a GNSS (global navigation satellite system) device based on, for example, GPS (global positioning system), beidou (Beidou), GLONASS, or Galileo (Galileo)), or a land-based device), a tablet computer, a laptop computer, a netbook, a smart book, a personal computer, a smart device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, virtual reality glasses, smart wristband, smart jewelry (e.g., a smart ring, smart bracelet)), an drone, a robot/robotic device, a vehicle-mounted device, a meter (e.g., a parking meter, a gas meter, a water meter), a monitor, a gas pump, an appliance (e.g., a kitchen appliance, a washing machine, a dryer), a location tag, a medical/healthcare device, an implant, a sensor/actuator, a display, or any other device configured to communicate via wireless or any other suitable wireless medium. 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 appliances or vehicles, meters, etc.

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

The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 over one or more carriers. The term "carrier" may refer to a set of radio frequency (radio frequency) spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, the carrier for the communication link 125 may include a portion (e.g., a bandwidth portion (BWP)) of a radio frequency spectrum band operating in accordance with one or more physical layer channels of a given radio access technology (e.g., LTE-A, LTE-a Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling to coordinate carrier operation, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. According to the carrier aggregation configuration, the UE 115 may be configured with a plurality of downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with Frequency Division Duplex (FDD) and Time Division Duplex (TDD) component carriers.

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

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

The carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a plurality of bandwidths determined 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 wireless communication system 100 (e.g., base station 105, UE 115, or both) may have a hardware configuration that supports communication over a particular carrier bandwidth or may be configured to support communication over one carrier bandwidth of a set of carrier bandwidths. In some examples, wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate over part (e.g., sub-band, BWP) or all of the carrier bandwidth.

The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using a multi-carrier 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). Thus, the more resource elements received by the UE 115, the higher the order of the modulation scheme, and the higher the data rate of the UE 115. The wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may also improve the data rate or data integrity of communications with the UE 115.

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

Each frame may include a plurality of consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may also be divided into multiple slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on the subcarrier spacing. Each slot may include multiple symbol periods (e.g., depending on the length of the cyclic prefix pre-applied to each symbol period). In some wireless communication systems 100, a time slot may also be divided into a plurality of minislots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N _f ) Sampling period. The duration of the symbol period may depend on the subcarrier spacing or the operating frequency band.

A subframe, slot, minislot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a Transmission Time Interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 (e.g., in a burst of shortened TTIs (sTTI)) may be dynamically selected.

The physical channels may be multiplexed on the carrier according to various techniques. For example, the physical control channels and physical data channels may be multiplexed on the downlink carrier using one or more of Time Division Multiplexing (TDM), frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques. The control region (e.g., control resource set (CORESET)) of the physical control channel may be defined by a plurality of symbol periods and may extend across a system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESET) may be configured for a group of UEs 115. For example, one or more UEs 115 may monitor or search for control information in a control region according to one or more sets of search spaces, and each set of search spaces may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of control channel candidates may refer to the number of control channel resources (e.g., control Channel Elements (CCEs)) associated with the encoded information in the control information format having a given payload size. The set of search spaces may include a common set of search spaces configured to transmit control information to a plurality of UEs 115, and a UE-specific set of search spaces configured to transmit control information to a particular UE 115.

Each base station 105 may provide communication coverage via one or more cells, such as a macrocell, a small cell, a hotspot, or other type of cell, or any combination thereof. The term "cell" may refer to a logical communication entity for communicating (e.g., via a carrier) with the base station 105 and may be associated with an identifier (e.g., physical Cell Identifier (PCID), virtual Cell Identifier (VCID), etc.) for distinguishing between neighboring cells. In some examples, a cell may also refer to a geographic coverage area 110 or a portion (e.g., a sector) of geographic coverage area 110 over which a logical communication entity operates. Depending on various factors, such as the capabilities of the base station 105, these cells may range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or include a building, a subset of buildings, or an external space between or overlapping geographic coverage areas 110, and so forth.

The macro cell typically covers a relatively large geographic area (e.g., several kilometers in radius) and may allow the UE 115 unrestricted access with subscription services with the network provider supporting 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 a different (e.g., licensed, unlicensed) frequency band as the macro cell. The small cell may provide unrestricted access to the UE 115 with subscription services with the network provider or may provide restricted access to the UE 115 associated with the small cell (e.g., UEs 115 in a Closed Subscriber Group (CSG), UEs 115 associated with users in a home or office). The base station 105 may support one or more cells and may also use one or more component carriers to support communications on the one or more cells.

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 for different types of devices.

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

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 a data communication technology that allows devices to communicate with each other or with the base station 105 without human intervention. In some examples, the M2M communication or MTC may include communication from a sensor or meter integrated device to measure or capture information and relay such information to a central server or application that utilizes or presents the information to a person interacting with the application. Some UEs 115 may be designed to collect information or to implement automated behavior of a machine or other device. 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 business charging. In an aspect, the techniques disclosed herein may be applicable to MTC or IoT UEs. MTC or IoT UEs may include MTC/enhanced MTC (eMTC, also known as CAT-M, CAT M1) UEs, NB-IoT (also known as CAT NB 1) UEs, and other types of UEs. eMTC and NB-IoT may refer to future technologies that evolve from or are based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (enhanced further eMTC), and eMTC (large scale MTC), and NB-IoT may include eNB-IoT (enhanced NB-IoT) and FeNB-IoT (further enhanced NB-IoT).

The wireless communication system 100 may be configured to support ultra-reliable communications or low-latency communications or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low latency communications (URLLC) or mission critical communications. The UE 115 may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission critical functions). Ultra-reliable communications may include private communications or group communications, and may be supported by one or more mission critical services, such as mission critical push-to-talk (MCPTT), mission critical video (MCVideo), or mission critical data (MCData). Support for mission critical functions may include priority of services, and mission critical services may be used for public safety or general business applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

In some examples, the UE 115 is also capable of directly communicating with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in the group may be outside the geographic coverage area 110 of the base station 105 or may not be able to receive transmissions from the base station 105. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates scheduling of resources for D2D communications. In other cases, D2D communication is performed between UEs 115 without involving base station 105.

In some systems, D2D communication link 135 may be an example of a communication channel (such as a side link communication channel) between vehicles (e.g., UEs 115). In some examples, the vehicle may communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination thereof. The vehicle may transmit signals related to traffic conditions, signal scheduling, weather, safety, emergency, or any other information related to the V2X system. In some examples, vehicles in the V2X system may communicate with a roadside infrastructure (such as a roadside unit) or with a network, or with both, via one or more network nodes (e.g., base stations 105) using vehicle-to-network (V2N) communications.

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 (5 GC), which may include at least one control plane entity (e.g., a Mobility Management Entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a User Plane Function (UPF)) that routes packets or interconnections to external networks. The control plane entity may manage non-access stratum (NAS) functions of the UE 115 served by the base station 105 associated with the core network 130, such as mobility, authentication, and bearer management. User IP packets may be transferred through a user plane entity that may provide IP address assignment as well as other functions. The user plane entity may be connected to IP services 150 of one or more network operators. IP services 150 may include access to the internet, intranets, IP Multimedia Subsystem (IMS), or packet switched streaming services.

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

The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300MHz to 3GHz is called an Ultra High Frequency (UHF) region or decimeter band (decimeter band) because the wavelength ranges from about 1 decimeter to 1 meter long. UHF waves may be blocked or redirected by building and environmental features, but these waves may penetrate structures sufficient for macro cells to serve UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than transmission of smaller frequencies and longer waves using the High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum below 300 MHz.

The wireless communication system 100 may also operate in the ultra-high frequency (SHF) region using a frequency band from 3GHz to 30GHz (also referred to as a centimeter-band), or in the extremely-high frequency (EHF) region of the spectrum (e.g., from 30GHz to 300 GHz) (also referred to as a millimeter-band). In some examples, wireless communication system 100 may support millimeter wave (mmW) communication between UE 115 and base station 105, and EHF antennas of respective devices may be smaller and more closely spaced than UHF antennas. In some examples, this may facilitate the use of an antenna array within the device. However, the propagation of EHF transmissions may be subject to greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the frequency band designation usage across these frequency regions may vary from country to country or regulatory agency.

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

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

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

The base station 105 or UE 115 may use beam scanning techniques as part of the beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) for 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 base station 105, or by a receiving device such as UE 115) the beam direction for later transmission or reception by base station 105.

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

In some examples, the transmission by the device (e.g., by the base station 105 or the 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 for one or more beam directions and the feedback may correspond to a configured number of beams across a system bandwidth or one or more subbands. The base station 105 may transmit reference signals (e.g., cell-specific reference signals (CRSs), channel state information reference signals (CSI-RS)), which may be precoded or uncoded. 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 codebook, a linear combined codebook, a port selection codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying beam directions for subsequent transmission or reception by UE 115) or for transmitting signals in a single direction (e.g., for transmitting data to a receiving device).

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

The wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communications 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 communicate over logical channels. The Medium Access Control (MAC) layer may perform priority processing and multiplex logical channels into transport channels (transport channels). The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, a Radio Resource Control (RRC) protocol layer may provide establishment, configuration, and maintenance of an RRC connection between the UE 115 and the base station 105 or core network 130 supporting radio bearers of user plane data. At the physical layer, transport channels may be mapped to physical channels.

The UE 115 and the base station 105 may support retransmission of data to increase the likelihood of successfully receiving the data. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data over the communication link 125. HARQ may 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)). Under severe radio conditions (e.g., low signal-to-noise conditions), HARQ may improve throughput at the MAC layer. In some examples, a device may support HARQ feedback for the same slot, where the device may provide HARQ feedback in a particular slot for data received in a previous symbol in the slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

In some cases, UE 115 may be configured to transmit multiple repetitions of UCI and uplink data, wherein a spectral efficiency ratio of uplink data to UCI is scaled based on one or more parameters associated with the multiple repetitions. In some cases, UE 115 may receive an uplink grant from base station 105 with a set of uplink resources for uplink data transmissions, where the uplink data transmissions are to be sent in a repetition set, and UCI is to be multiplexed with at least some of the repetitions. The uplink grant may provide a set of uplink resources and UE 115 may determine a first subset of uplink resources for UCI (e.g., a number of REs for UCI) and a second subset of uplink resources for uplink data transmission. The first subset of uplink resources may be determined based on a spectral efficiency ratio provided by the base station 105 as an offset value (e.g., a beta-offset provided to the UE 115), wherein the offset value is scaled based on one or more parameters associated with the plurality of repetitions. The one or more parameters may include, for example, a number of repetitions of uplink data, a number of repetitions of a particular UCI, whether multiple beams are used to transmit the instances of the repetition, a type of UCI, or any combination thereof.

Fig. 2 illustrates an example of a wireless communication system 200 in accordance with aspects of the present disclosure, the wireless communication system 200 supporting uplink control information multiplexing techniques using multiple repeated uplink communications. In some examples, wireless communication system 200 may implement aspects of wireless communication system 100. The wireless communication system 200 may include a base station 105-a and a UE 115-a, which may be examples of base stations or UEs described above with reference to fig. 1. Base station 105-a and UE 115-a may communicate within coverage area 110-a using downlink 205 and uplink 210 and with each other using the techniques described above with reference to fig. 1. The wireless communication system 200 may provide for repetition of certain communications in order to increase the likelihood of successful reception and decoding of the communications and thereby increase system reliability and efficiency.

In the example of fig. 2, base station 105-a may transmit and UE 115-a may receive configuration information providing duplicate configuration 215. In accordance with the techniques discussed herein, repetition configuration 215 may indicate, for example, an offset value of a ratio of spectrum efficiency between UCI and uplink data, where the uplink transmission has UCI multiplexed with uplink data, and scaling information for scaling the offset value based on one or more parameters of the uplink repetition, and so forth. The base station 105-a may also provide an uplink grant 220 that allocates uplink resources to the UE 115-a, including a plurality of repeated uplink resources for one or more uplink communications.

UCI may include various types of control information to be sent by UE 115-a to base station 105-a, such as HARQ feedback based on results of decoding other downlink communications from base station 105-a, CSI information associated with one or more TRPs (e.g., CSI part 1 and CSI part 2 information), one or more status reports or scheduling requests, uplink reference signals, or any combination thereof. The repetition techniques for one or more TRPs as discussed herein may provide an enhanced likelihood of successful reception and decoding of a transmission and thereby reduce the likelihood of a need to retransmit uplink communications. In this example, the UE 115-a may be allocated uplink resources 225, and the uplink resources 225 may include resources for multiple repetitions of uplink data transmission, where one or more repetitions have UCI multiplexed with uplink data. In this example, a first UCI repetition 230 (UCI 0) and a second UCI repetition 235 (UCI 1) are multiplexed with repetition of uplink data.

Uplink repetition may be transmitted according to a repetition technique, where different PUSCH transmission opportunities (e.g., repetitions) corresponding to the same Transport Block (TB) are transmitted in different time slots (e.g., in repetition type a defined in the 3GPP specification) or in minislots (e.g., in repetition type B defined in the 3GPP specification). The number of repetitions may be configured in a repetition configuration 215 (e.g., RRC configuration), or may be dynamically indicated in downlink control information providing uplink grant 220 (e.g., in a TDRA field of DCI defined in 3GPP specifications). In some cases, all repetitions are transmitted using the same beam (e.g., SRS Resource Indicator (SRI) field of DCI is applied to all repetitions). SRI is a field in DCI that determines beam/power control of PUSCH by pointing to one or more SRS resources within a SRS resource set. When different PUSCH repetitions are intended to be received at different TRP/panels/antennas of the base station 105-a, the same beam of all repetitions may not be optimal, and in this case, the uplink repetition may be associated with different SRI fields and thus belong to two groups, with each group having its own beam and power control. To achieve this, the different repetitions may correspond to two different sets of SRS resources (e.g., the DCI indicates two beams and two sets of power control parameters by indicating one or more SRS resources within each of the two sets of SRS resources).

In some cases, UE 115-a may determine the number of REs in an uplink repetition (e.g., PUSCH repetition) for UCI transmission using an indicated offset value (e.g., configured (in RRC) or indicated (by DCI)) scaled by a scaling factor, where the scaling factor is determined for each repetition or each UCI separately based at least in part on one or more parameters associated with the UCI and/or repetition. In some cases, one of the parameters may include a number of repetitions (e.g., a number of PUSCH repetitions), or a number of repetitions over which no UCI is multiplexed. In this case, a greater number of repetitions provides more resources for the uplink shared channel (UL-SCH) as a whole, which means that if UCI is multiplexed in a subset of repetitions (e.g., in one of them), more REs can be allocated to UCI with relatively less impact on the reliability of uplink data transmission. In this case, the UE 115-a may scale up the offset value offset by the number of PUSCH repetitions or by the number of PUSCH repetitions over which UCI is not multiplexed.

In some cases, one of the parameters may include a number of PUSCH repetitions over which a particular UCI is multiplexed (e.g., based on whether the UCI includes CSI, HARQ feedback, SR, etc.). For example, aperiodic CSI (a-CSI), CSI reports may be multiplexed on two repetitions, and thus the offset value may be scaled down by a factor of two to keep the total number of REs for a-CSI the same as if a-CSI were multiplexed on one PUSCH repetition. In some cases, the one or more parameters may include whether PUSCH repetition is associated with one SRS resource set (e.g., a set of transmission parameters for all repetitions, such as one beam, a set of power control parameters, one precoding) or two SRS resource sets (e.g., two sets of transmission parameters for two sets of repetitions, which may be for two TRPs or antenna panels). In this case, scaling up or down the offset value may be ineffective because the motivation for two sets of transmission parameters is to block reliability in the scenario (e.g., one TRP may be randomly blocked). In some cases, when two SRS resource sets are configured, the offset value of one of the resource sets may be enlarged or reduced based on the number of repetitions of each beam (e.g., the number of repetitions of one SRI differs from the number of repetitions of a different SRI).

In some cases, the one or more parameters may include a type of UCI. For example, when UCI is CSI, scaling may be a function of whether CSI is a-CSI, semi-persistent CSI (SP-CSI), or periodic CSI (P-CSI). For example, in some cases, only a-CSI may be multiplexed with UCI on two PUSCH repetitions, while UCI is multiplexed on only one PUSCH repetition for other UCI types. Furthermore, the required reliability level of the A-CSI may be different from that of the P-CSI. Thus, for a-CSI versus P-CSI or SP-CSI, the offset value may be scaled differently at the UE. For example, the offset value of a-CSI may be scaled down from the indicated offset value, while the offset value of P-CSI or SP-CSI may not be scaled down from the indicated offset value. Other types of UCI may include HARQ ACK/NACK feedback, scheduling Request (SR), buffer Status Report (BSR), etc., which may have different scaling factors in some cases. In some cases, different combinations of one or more parameters may be used to determine the scaling factor of the signaled offset value.

Fig. 3 illustrates an example of an encoding and multiplexing scheme 300 supporting uplink control information multiplexing techniques using multiple repeated uplink communications in accordance with aspects of the disclosure. In some examples, the encoding and multiplexing scheme 300 may implement aspects of the wireless communication system 100 or 200.

As discussed, in some cases, one or more repetitions of UCI may be multiplexed with uplink data in PUSCH communications from a UE (e.g., UE 115 of fig. 1 or fig. 2) to a base station (e.g., base station 105 of fig. 1 or fig. 2). As discussed herein, the determination of PUSCH resources on which UCI is to be multiplexed may be based on various configuration parameters and UCI itself. In this example, UCI 305 may be identified at the UE, and at 310, the UE may determine the number of resource elements in PUSCH for UCI transmission. This determines the number of bits of the rate matching output and also determines the mother code length for encoding (e.g., for polar encoding). The UE may then perform channel coding at 315, followed by rate matching at 320, and modulation at 325. Then, at 330, the modulation symbols of uci are mapped to some REs of PUSCH. The RE mapping may be based on a set of rules and may depend on UCI type, PUSCH demodulation reference signal (DMRS) symbol position, etc. These steps are performed for each UCI overlapping PUSCH (e.g., first for HARQ-ACK/NACK information (if present), then for CSI part 1 (if present), then for CSI part 2 (if present)). In this case, the transmitted UCI uses the same modulation order and the same number of layers as PUSCH communication (this is indicated in DCI scheduling PUSCH).

When determining the number of resource elements at 310, the UE may determine a number Q', which is the number of coded modulation symbols per layer (i.e., the number of REs for UCI), and is determined first for HARQ-ACK/NAK, then CSI part 1, then CSI part 2. For HARQ ACK/NACK information, in case PUSCH transmission is also used for uplink data, the number Q' may be determined based on the following equation:

wherein the number (O _ACK +L _ACK ) Corresponding to the HARQ ACK/NACK payload size.Is a value configured at the UE (e.g., via RRC signaling or dynamically indicated in DCI scheduling PUSCH) that controls the spectrum efficiency ratio of PUSCH to UCI. />The number of (2) corresponds to the total number of PUSCH REs. />The number of (a) corresponds to the number of coded bits of uplink data (i.e., uplink shared channel (UL-SCH) bits). The number of α corresponds to a scaling factor to limit the number of REs allocated to UCI on PUSCH and +.>Corresponds to the maximum number of REs that can be used for UCI.

In the case where UCI is transmitted using PUSCH and uplink data is not transmitted using PUSCH, the number Q' of HARQ ACK/NACK information may be determined based on the following formula:

wherein the number used in the formula corresponds to the same number discussed above for the case of uplink data transmission in PUSCH. In this case, the total number of PUSCH REs does not exist, and the number of coded bits of uplink data (UL-SCH) is replaced with R.Q _m Wherein R corresponds to the code rate of PUSCH, and Q _m Corresponding to the modulation order of PUSCH.

In the case that UCI includes CSI part 1 information to be transmitted using PUSCH, and in the case that UCI includes both CSI part 1 and CSI part 2 information, the value of Q 'may be determined in a similar manner, the maximum number of REs that may be used for UCI (as scaled by the number α) is adjusted to consider the information for HARQ ACK/NACK (i.e., Q' _ACK ) And for CSI part 2 information, adjusts the maximum number of REs that can be used for UCI to consider harq ack/NACK and CSI part 1 information. In each case the number of the individual cells to be processed,(interchangeably referred to as beta-offset,and is an example of an offset value discussed herein) is a value configured at the UE (e.g., via RRC signaling or dynamically indicated in DCI scheduling PUSCH) that controls the spectrum efficiency ratio of PUSCH to UCI. In some cases, the value of the beta-offset may be provided to the UE in one list (e.g., in the case of semi-static indication by RRC) or up to four lists (e.g., in the case of dynamic indication by DCI). Within each list, the beta-offset value may be RRC configured. In the case of dynamic indication of offset values, the DCI may indicate which list to use (e.g., 2 bits in DCI scheduling PUSCH). In some cases, each list may include seven beta-offset values, three for HARQ-acks (e.g., UCI bits+.2; 2 < UCI bits+.11; 11 < UCI bits), two for each of CSI part 1 and CSI part 2 (e.g., 2 < UCI bits+.11, 11 < UCI bits). The value of the beta-offset may then be determined based on an index between 0 and 31, which is mapped to the actual offset value in one or more tables (which may be separate for HARQ-Ack and CSI). In this case, the value of the beta-offset may be determined at the UE, and then the scaling factor discussed herein may be applied to the determined beta-offset value when determining the number of REs for UCI.

Fig. 4 illustrates an example of uplink resources 400 with UCI and PUSCH multiplexing that support uplink control information multiplexing techniques using multiple repeated uplink communications, according to aspects of the present disclosure. In some examples, the uplink resources with UCI and PUSCH 400 may implement aspects of wireless communication system 100 or 200. In this example, a plurality of uplink resources 405 may be allocated for uplink communications from a UE (e.g., UE 115 of fig. 1 or fig. 2) to a base station (e.g., base station 105 of fig. 1 or fig. 2). The uplink resources 405 may be indicated in an uplink grant, such as provided in DCI 410.

In the example shown in fig. 4, uplink resources 405 may be applicable to implementations or instances when a UE is configured to support UCI multiplexing operations on multiple uplink repetitions, such as providing CSI reports, for example. For example, UCI multiplexing may be applicable to implementations or instances when UE 115 is configured to provide CSI reports on PUSCH repetition, CSI reports using multiple antenna panels, and/or CSI reports on multiple directional beams using one or more antenna panels. In some cases, one or more different types of UCI may be repeatedly multiplexed with PUSCH in addition to CSI or in lieu thereof.

In some cases, the UE may receive a DCI message 410 that schedules one or more PUSCHs in a set of PUSCH repetitions 415, where UCI multiplexing may be used for UCI to be sent to the base station (e.g., scheduling the UE to send or multiplex UCI on the one or more PUSCH repetitions 415). Based at least in part on DCI message 410, ue 115 may multiplex UCI on one or more PUSCH repetitions of PUSCH repetition set 415. As discussed herein, a scaling factor may be applied to the offset value used to determine the number of REs for UCI. For example, for PUSCH repetition 415 with a-CSI multiplexed thereon, the ue may use scaled beta offset β' according to the following equation:

beta' = (total number of repetitions) ·beta.

In this case, the offset value will be scaled up based on the number of repetitions. In other examples, some PUSCH repetitions may not include UCI, and in this case, the offset value may be scaled up by the number of repetitions including UCI.

In another example, the offset value may be scaled based on the number of PUSCH repetitions and the particular type of UCI. For example, for PUSCH repetition with a-CSI multiplexed thereon, the UE may use the scaled beta offset β' according to the following equation:

In this case, for some type of UCI, the offset value may be scaled up based on the number of repetitions and scaled down based on the number of repetitions. If different types of UCI are multiplexed on the repetition that does not include a-CSI, the UE may use the beta offset β "=β.

In a further example, the offset value may be scaled based on the beam or antenna panel used for repetition. An example of such scaling is discussed with reference to fig. 5.

Fig. 5 illustrates an example of uplink resources 500 with UCI and PUSCH multiplexing that support uplink control information multiplexing techniques using multiple repeated uplink communications, according to aspects of the present disclosure. In some examples, the uplink resources with UCI and PUSCH 500 may implement aspects of wireless communication system 100 or 200. In this example, a plurality of uplink resources 505 may be allocated for uplink communications from a UE (e.g., UE 115 of fig. 1 or fig. 2) to a base station (e.g., base station 105 of fig. 1 or fig. 2). The uplink resources 505 may be indicated in an uplink grant, such as provided in DCI 510.

In the example shown in fig. 5, uplink resources 505 may be suitable for implementation or example when a UE is configured to support UCI multiplexing operations on multiple uplink repetitions, as discussed herein. In some cases, the UE may receive a DCI message 510 that schedules one or more PUSCHs in PUSCH repetition sets 515 and 520, where UCI multiplexing may be used for UCI to be sent to the base station (e.g., scheduling the UE to send or multiplex UCI on one or more PUSCH repetitions 515, 520). Based at least in part on DCI message 510, ue 115 may multiplex UCI on one or more PUSCH repetitions of PUSCH repetition sets 515, 520.

The UE 115 may determine a first subset 515 of PUSCH repetitions and a second subset 520 of PUSCH repetitions. In some examples, a first subset 515 of PUSCH repetitions may correspond to a first beam or a first set of power control parameters (e.g., based on a first SRI), while a second subset 520 of PUSCH repetitions may correspond to a second beam or a second set of power control parameters (e.g., based on a second SRI). Thus, a first subset 515 of PUSCH repetitions may correspond to a first directional beam (e.g., a first mmW beam), while a second subset 520 of PUSCH repetitions may correspond to a second directional beam (e.g., a second mmW beam) different from the first directional beam. In some examples, the UE 115 may multiplex UCI on one or more PUSCH repetitions of the PUSCH repetition sets 515, 520. The first directional beam may be associated with a corresponding SRI, TCI, TPMI or SRS set identifier or any combination thereof. Similarly, the second directional beam may be associated with a corresponding different SRI, TCI, TPMI or SRS set identifier or any combination thereof. Additionally, the first directional beam may belong to a first antenna panel and the second directional beam may belong to a second antenna panel different from the first antenna panel.

The number of REs for multiplexed UCI may be determined by the UE according to techniques discussed herein. For example, an offset value may be provided to the UE and used to determine a number of REs for UCI, which may be scaled based on one or more parameters associated with uplink transmission repetition. In some cases, the offset values may be scaled based on the SRI associated with the repetition such that the repetition of the first subset of PUSCH repetitions 515 and the repetition of the second subset of PUSCH repetitions 520 have scaled offset values based on the beams for one or more repetitions. For example, if a first instance of UCI is transmitted in one repetition of a first subset of PUSCH repetitions 515 and a second instance of UCI is transmitted in one repetition of a second subset of PUSCH repetitions 520, in which case the offset value may remain un-scaled to provide the same number of UCI REs as the single repetition of each beam/SRI. In some cases, the offset value may be scaled based on the number of repetitions, the beam used, and the type of UCI. For example, for PUSCH repetition with no a-CSI multiplexing thereon but other types of UCI multiplexing thereon, the usage of scaled beta offset β″ may be determined according to the following equation:

In this case, the offset value may be scaled up based on the number of repetitions of each beam and scaled down based on the number of repetitions of a certain type of UCI.

Fig. 6 illustrates an example of a process flow 600 supporting uplink control information multiplexing techniques using multiple repeated uplink communications in accordance with aspects of the disclosure. In some examples, the process flow 600 may implement aspects of the wireless communication system 100 or 200. As described herein, the process flow 600 may be implemented by the UE 115-b and the base station 105-b. In the following description of process flow 600, communications between UE 115-b and base station 105-b may be sent in a different order than the illustrated example, or operations performed by UE 115-b and base station 105-b may be performed in a different order or at different times. Some operations may also be omitted from process flow 600 and other operations may be added to process flow 600.

In some examples, the operations shown in process flow 600 may be performed by hardware (e.g., including circuitry, processing blocks, logic components, and other components), code executed by a processor (e.g., software or firmware), or any combination thereof. The following alternative examples may be implemented in which some steps are performed in a different order than described or not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.

At 605, the base station 105-b may send configuration information to the UE 115-b. In some cases, the base station 105 may transmit RRC signaling including an indication of the beta-offset value for UCI multiplexing. In some cases, the configuration information may include an indication to perform offset value scaling based on one or more parameters of the uplink repetition. At 610, ue 115-b may determine a beta-offset value associated with one or more UCI types based at least in part on the configuration information.

At 615, the base station 105-b may allocate uplink resources to the UE 115-b. In some cases, uplink resources may be allocated to provide multiple repetitions of uplink data transmission (e.g., multiple PUSCH repetitions). Furthermore, in some cases, different subsets of uplink resources may have different SRIs and thus be associated with different beams/panels. At 620, the base station 105-b may transmit an uplink grant to the UE 115-b indicating the allocated uplink resources and associated repetition information. In some cases, the indication of the offset value may be dynamically indicated using an uplink grant, as discussed herein.

At 625, ue 115-b may determine that UCI is to be repeatedly multiplexed with one or more PUSCHs. In some cases, the determination of UCI multiplexing may be based on one or more parameters associated with UCI, a configuration of UE 115-b for UCI multiplexing, or any combination thereof. At 630, ue 115-b may determine the beta-offset and scaling factor of UCI. The UE 115-b may make such a determination using one or more of the techniques discussed herein. At 635, ue 115-b may determine REs for UCI based on the scaled beta-offset value. In some cases, the number of REs for UCI is determined based solely on the scaled beta-offset value for each of one or more types of UCI (e.g., HARQ feedback, CSI part 1, CSI part 2).

At 640, ue 115-b may multiplex UCI and PUCCH REs in uplink repetition. For example, UE 115-b may perform channel coding, rate matching, and modulation of UCI REs, and may then map the modulation symbols of UCI to some REs of PUSCH to generate multiplexed data and UCI. At 645, ue 115-b may send a repetition of the uplink transmission, including the multiplexed UCI and PUSCH. At 650, the base station 105-b may receive the uplink transmission and decode the PUSCH and UCI. For example, the base station 105-b may decode PUSCH and UCI using soft combining techniques.

Scaling of the offset value may improve reliability and efficiency of communication by increasing the likelihood of successful decoding of uplink data and UCI by utilizing efficient signaling of uplink parameters. Such improvements may increase the efficiency of wireless communications by reducing the delay and reducing the number of retransmissions and provide efficient signaling of offset values according to established signaling techniques.

Fig. 8 illustrates a block diagram 800 of a device 805 that supports uplink control information multiplexing techniques using multiple repeated uplink communications, in accordance with aspects of the disclosure.

In some examples, configuration manager 940 may be configured or support means for receiving configuration information for two or more sets of uplink reference signal resources, and wherein the scaling factor is based on whether the repeated subset is associated with a single set of uplink reference signal resources or multiple sets of uplink reference signal resources.

The functions described herein may be implemented in hardware, software executed by a processor, or any combination thereof. Software should be construed broadly as an instruction, instruction set, code segment, program code, program, subroutine, software module, application, software package, routine, subroutine, object, executable, thread of execution, procedure or function, etc. Whether referred to as software, firmware, middleware, microcode, hardware description languages, or otherwise. If implemented in software for execution by a processor, the functions may be stored on or transmitted over as one or more instructions or code on a computer-readable medium. Other examples and implementations are within the scope of the present 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, hardwired, or a combination of any of these.

As used herein, the term "and/or," when used in a list of two or more items, means that any one of the listed items can be employed alone, or any combination of two or more of the listed items can be employed. For example, if a composition is described as comprising components A, B and/or C, the composition may comprise a alone; comprising B alone; solely comprising C; a combination of A and B; a combination of a and C; a combination of B and C; or a combination of A, B and C.

The term "determining" encompasses a wide variety of actions, and thus "determining" may include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database or another data structure), ascertaining and the like. Likewise, "determining" may include receiving (such as receiving information), accessing (e.g., accessing data in memory), and the like. Likewise, "determining" may include parsing, selecting, choosing, establishing, and other such similar actions.

In the drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If only a first reference label is used in the specification, the description applies to any one similar component having the same first reference label irrespective of the second or other subsequent reference labels.

The description set forth herein describes example configurations, with reference to the accompanying drawings, and is not intended to represent all examples that may be implemented or are within the scope of the claims. The term "exemplary" as used herein means "serving as an example, instance, or illustration," rather than "preferred" or "advantageous over other examples.
