Simultaneous PUCH-PUSCH with different priorities

Abstract

Methods, systems, and devices for wireless communication are described. The described techniques may provide for handling of priority indications in a scenario that supports a simultaneous physical uplink control channel (PUCCH)-physical uplink shared channel (PUSCH). For example, a wireless communication system may configure a simultaneous PUCCH-PUSCH across two or more carriers (e.g., via radio resource control (RRC) signaling), where piggybacking of feedback information on uplink shared channel transmissions may be disabled. Further, a grant (e.g., downlink control information (DCI) for scheduling PUSCH transmissions) may include a priority index field to indicate a priority associated with a transmission or resource scheduled by the grant. The described techniques may provide for efficient handling of priority indications associated with scheduled transmissions that overlap when supporting a simultaneous PUCCH-PUSCH (e.g., techniques are provided for performing or discarding the overlapped scheduled transmissions based on any priority indications associated with scheduled transmissions that overlap when a simultaneous PUCCH-PUSCH is enabled).

Technical Field

[0004] The following relates generally to wireless communications, and more particularly to simultaneous Physical Uplink Control Channel (PUCCH)-Physical Uplink Shared Channel (PUSCH) with different priorities. Background Art

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency and power). Examples of such multiple access systems include fourth generation (4G) systems 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 use techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA) or discrete Fourier transform extended orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node supporting communication of multiple communication devices simultaneously, wherein the communication device may also be referred to as user equipment (UE). Summary of the invention

[0006] The described technology relates to improved methods, systems, devices and apparatuses for supporting simultaneous physical uplink control channel (PUCCH)-physical uplink shared channel (PUSCH) with different priorities. In general, the described technology provides simultaneous PUCCH and PUSCH transmissions. For example, a wireless communication system may support and enable simultaneous PUCCH-PUSCH across two or more carriers. In some cases, in order to effectively support simultaneous PUCCH-PUSCH, a carrier configured for PUSCH transmission may be further configured to disable control information (e.g., a carrier configured for PUSCH in a simultaneous PUCCH-PUSCH scenario may be configured as a data-only carrier). For example, a wireless communication system may configure (e.g., via radio resource control (RRC) signaling) simultaneous PUCCH-PUSCH across two or more carriers, wherein piggybacking of feedback information on uplink shared channel transmissions may be disabled.

[0007] In other words, the wireless communication system may configure simultaneous PUCCH-PUSCH so that feedback information of the PUCCH (e.g., hybrid automatic repeat request (HARQ) feedback, periodic channel state information (P-CSI), etc.) may not be piggybacked (e.g., multiplexed) on the PUSCH. In addition, the described techniques may provide efficient handling of priority indications in scenarios supporting simultaneous PUCCH-PUSCH (e.g., techniques are provided for performing or dropping an overlapping scheduled transmission based on any priority indication associated with the overlapping scheduled transmission when simultaneous PUCCH-PUSCH is enabled).

[0040] A user equipment (UE) may send feedback information to a base station based on successful or unsuccessful reception and decoding of a downlink transmission from a base station. The base station may initially schedule resources for downlink transmissions from the base station in a physical downlink shared channel (PDSCH) by sending a downlink grant indicating the resources to the UE. The UE may then monitor the resources and may send feedback information based on successful or unsuccessful reception of the downlink transmission. The UE may send feedback information to the base station in a physical uplink control channel (PUCCH) transmission. For example, the UE may receive an uplink grant for scheduling hybrid automatic repeat request (HARQ) feedback in the PUCCH.

[0041] In some cases, the UE may also receive an uplink grant for scheduling other transmissions (e.g., data transmissions) in a physical uplink shared channel (PUSCH). In some cases, the PUCCH may be scheduled for a time that overlaps in time with the PUSCH. The overlap may be at the symbol level (i.e., the PUCCH and PUSCH are scheduled in one or more symbols at the same time in time) or at the slot level (i.e., the PUCCH and PUSCH are scheduled in the same slot). In this case, the UE may use the PUSCH to send feedback information instead of sending the feedback information in the overlapping PUCCH. For example, the UE may "piggyback" uplink control information (UCI) (e.g., HARQ feedback, periodic channel state information (P-CSI)) on the PUSCH. In other examples, the UE may receive an uplink grant that schedules a PUSCH transmission that overlaps in time with a scheduled PUCCH. In this case, the UE may similarly piggyback (eg, multiplex) UCI ​​associated with the PUCCH transmission onto the PUSCH (eg, and the UE may drop the PUCCH to avoid simultaneous PUCCH-PUSCH transmissions).

[0042] According to the techniques described herein, a wireless communication system may support simultaneous PUCCH-PUSCH transmissions. For example, a wireless communication system may support and enable simultaneous PUCCH-PUSCH across two or more carriers. In some cases, in order to effectively support simultaneous PUCCH-PUSCH, a carrier configured for PUSCH transmission may be further configured to disable communication of control information via the carrier (e.g., a carrier configured for PUSCH in a simultaneous PUCCH-PUSCH scenario may be configured as a data-only carrier or a "non-piggyback" carrier). For example, a wireless communication system may configure (e.g., via radio resource control (RRC) signaling) simultaneous PUCCH-PUSCH across two or more carriers, wherein piggybacking of feedback information on uplink shared channel transmissions may be disabled. In other words, a wireless communication system may configure simultaneous PUCCH-PUSCH so that feedback information (e.g., HARQ feedback, P-CSI) of the PUCCH may not be piggybacked (e.g., multiplexed) on the PUSCH.

[0043] For example, for some uplink carrier aggregation (CA) scenarios (e.g., for inter-frequency range (inter-FR) CA, inter-band CA, CA across carriers with different subcarrier spacing (SCS), CA in licensed assisted access (LAA) systems), disabling UCI piggybacking on PUSCH for some uplink carriers can provide more efficient communication. Configuring simultaneous PUCCH-PUSCH for some uplink carriers and disabling UCI piggybacking on PUSCH can allow some secondary cells (Scells) to be used only for data, which can provide more efficient processing of control information (e.g., improved HARQ processes), improved data throughput (e.g., on PUSCH), decoupled operation of two uplink carriers, etc.

[0044] In addition, the described techniques may provide for handling of priority indications in scenarios where simultaneous PUCCH-PUSCH is supported. For example, a grant (e.g., downlink control information (DCI) for scheduling PUSCH transmissions) may include a priority index field to indicate a priority associated with a transmission or resource scheduled by the grant. The described techniques may provide for efficient handling of priority indications associated with scheduled transmissions that overlap when simultaneous PUCCH-PUSCH is supported (e.g., techniques are provided for performing or discarding an overlapping scheduled transmission based on any priority indication associated with the overlapping scheduled transmission when simultaneous PUCCH-PUSCH is enabled).

[0045] Various aspects of the present disclosure are initially described in the context of a wireless communication system. Simultaneous PUCCH-PUSCH transmission diagram examples and process flow examples are then described that illustrate various aspects of the discussed techniques. Various aspects of the present disclosure are further illustrated and described by reference to apparatus diagrams, system diagrams, and flow diagrams related to simultaneous PUCCH-PUSCH with different priorities.

[0046] Figure 1 An example of a wireless communication system 100 supporting simultaneous PUCCH-PUSCH with different priorities in accordance with aspects of the present disclosure is shown. The wireless communication system 100 includes 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 cases, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low latency communications, communications with low-cost and low-complexity devices, or a combination thereof.

[0047] 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 stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base stations 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 support communication of signals according to one or more radio access technologies.

[0048] 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 UEs 115 may be devices of different forms or with different capabilities. Figure 1 Some example UEs 115 are shown. Figure 1 As shown, the UE 115 described herein is capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices).

[0049] The base stations 105 may communicate with the core network 130, or 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 via 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.

[0050] One or more of the base stations 105 described herein may include or may be referred to by one of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a Node B, an eNode B (eNB), a next generation Node B or a giga-Node B (any of which may be referred to as a gNB), a Home Node B, a Home eNode B, or other suitable terminology.

[0051] 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 term, where a "device" may also be referred to as a unit, a station, a terminal or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may also 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 devices, or vehicles, meters, etc.

[0052] like Figure 1 As shown, the UE 115 described herein is capable of communicating with various types of devices, such as other UEs 115 that may sometimes act as relays, or base stations 105 and network devices including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations.

[0053] The UE 115 and the base station 105 can communicate with each other wirelessly via one or more communication links 125 through one or more carriers. The term "carrier" may refer to a set of radio spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, the carrier used for the communication link 125 may include a portion of a radio spectrum band (e.g., a bandwidth portion (BWP)) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating operations for the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. According to the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0054] 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. 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 according to a channel grid for discovery by UE 115. A carrier may be operated in a standalone mode, where initial acquisition and connection may be performed by UE 115 via the carrier, or may be operated in a non-standalone mode, where a connection is anchored using a different carrier (e.g., the same or different radio access technology).

[0055] 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 either downlink communications or uplink communications (e.g., in an FDD mode), or may be configured to carry both downlink communications and uplink communications (e.g., in a TDD mode).

[0056] A carrier may be associated with a particular bandwidth of a radio spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several 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)). A device of the wireless communication system 100 (e.g., a base station 105, a UE 115, or both) may have a hardware configuration that supports communications on a particular carrier bandwidth, or may be configurable to support communications on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or a UE 115 that supports simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, a BWP) or all of a carrier bandwidth.

[0057] The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system using MCM technology, a resource element may be composed of a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely proportional. 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 UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 can 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 also improve the data rate or data integrity used to communicate with UE 115.

[0058] One or more digital schemes for a carrier may be supported, where the digital scheme may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs with the same or different digital schemes. 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 of the UE 115 may be limited to the one or more active BWPs.

[0059] The time interval of the base station 105 or the UE 115 may be expressed as a multiple of a basic time unit, which may be, for example, T s =1 / (Δf max ·N f ) seconds sampling period, where Δf max It can indicate the maximum subcarrier spacing supported, N f The maximum supported discrete Fourier transform (DFT) size may be indicated. The time intervals of the communication resources may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0060] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of a cyclic prefix prepended to each symbol period). In some wireless communication systems 100, a time slot may also be divided into a plurality of mini-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., n f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0061] A subframe, a time slot, a mini-time slot, or a symbol may be a minimum 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 minimum scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of short TTIs (sTTIs)).

[0062] 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 be extended across a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a group of UEs 115. For example, one or more of UEs 115 may monitor or search a control region to obtain control information according to one or more search space sets, and each search space set may include one or more control channel candidates with one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with a coding information format for a given payload size. A search space set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set for sending control information to a specific UE 115.

[0063] 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 various combinations of the above). The term "cell" can refer to a logical communication entity used for communication 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 a logical communication entity operates. Such a cell can range from a smaller area (e.g., a structure, a subset of a structure) to a larger area based on various factors such as the capabilities of the base station 105. For example, a cell can be or include a building, a subset of a building, or an external space between or overlapping a geographic coverage area 110, and the like.

[0064] A macro cell typically covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs 115 that have a service subscription with a network provider that supports the macro cell. Small cells may be associated with lower-power base stations 105 than macro cells, and small cells may operate in the same or different (e.g., permitted, unpermitted, etc.) frequency bands as compared to macro cells. Small cells may provide unrestricted access to UEs 115 that have a service subscription with a network provider, or may provide restricted access to UEs 115 associated with small cells (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office, etc.). A base station 105 may support one or more cells, and may also support communications on one or more cells using one or more component carriers.

[0065] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0066] In some examples, the base stations 105 may be mobile and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0067] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timing, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timing, and transmissions from different base stations may not be aligned in time in some examples. The techniques described herein may be used for synchronous or asynchronous operation.

[0068] Some UEs 115, such as MTC devices or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices integrated with sensors or meters that measure or capture information and relay the information to a central server or application that may utilize the information 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, medical monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based commercial billing.

[0069] Some UEs 115 may be configured to employ an operating mode for reducing power consumption, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but does not support transmission and reception simultaneously). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power conservation techniques for UEs 115 include entering a power-saving deep sleep mode when not participating in active communications, operating over a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type 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.

[0070] 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 herein.

[0071] In some examples, UE 115 can also communicate directly with other UE 115 via device-to-device (D2D) communication links 135 (e.g., using a peer-to-peer (P2P) protocol or a D2D protocol). One or more UEs 115 utilizing D2D communication may be within a geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or unable 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, in which 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 communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0072] In some systems, the D2D communication link 135 can be an example of a communication channel, such as a sidelink communication channel between vehicles (e.g., UE 115). In some examples, vehicles can communicate using vehicle-to-all (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these communications. Vehicles can send information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in a V2X system can communicate with roadside infrastructure (such as roadside units), or communicate with a network using vehicle-to-network (V2N) communications via one or more network nodes (e.g., base station 105), or both.

[0073] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connection, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include: at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)); and at least one user plane entity that routes packets or interconnects to an external network (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UE 115 served by a base station 105 associated with the core network 130. User IP packets may be transmitted through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to a network operator IP service 150. The operator IP service 150 may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.

[0074] Some network devices, such as 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 UE 115 through several other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmit / receive points. 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 among various network devices (e.g., radio heads and ANCs) or merged into a single network device (e.g., base station 105).

[0075] 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). In some examples, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength ranges from about one decimeter to one meter long. UHF waves may be blocked or redirected by buildings and environmental features, but the waves can penetrate the structure sufficiently for the macrocell to provide services to the UE 115 located indoors. Compared to transmissions using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz, transmissions using UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0076] The wireless communication system 100 may also operate in a super high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also referred to as a centimeter band), or in an extremely high frequency (EHF) region (also referred to as a millimeter wave band) of the spectrum (e.g., from 30 GHz to 300 GHz). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and base station 105, and the EHF antenna of the corresponding device may be even smaller and more closely spaced than the UHF antenna. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and shorter distances than SHF transmissions or UHF transmissions. The technology disclosed herein may be used across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may differ from country to country or regulatory party.

[0077] The wireless communication system 100 can utilize both licensed radio spectrum bands and unlicensed radio spectrum bands. For example, the wireless communication system 100 can employ LAA, LTE-unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band (e.g., a 5 GHz industrial, scientific, and medical (ISM) band). When operating in an unlicensed radio spectrum band, devices such as base stations 105 and UEs 115 can employ carrier sensing for conflict detection and avoidance. In some examples, operations in an unlicensed band can be based on a carrier aggregation configuration combined with component carriers operating in a licensed band (e.g., LAA). Operations in an unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0078] The base station 105 or UE 115 may be equipped with multiple antennas, which may be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels, wherein the antenna arrays or antenna panels may support MIMO operations, or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly such as an antenna tower. In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having several rows and columns of antenna ports that the base station 105 may use to support beamforming of communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals sent via the antenna ports.

[0079] The base station 105 or UE 115 can use MIMO communication to adopt multipath signal propagation and increase spectrum efficiency by sending or receiving multiple signals via different spatial layers. Such a technology can be referred to as spatial multiplexing. For example, multiple signals can be transmitted by a transmitting device via different antennas or different antenna combinations. Similarly, multiple signals can be received by a receiving device via different antennas or different antenna combinations. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) for sending multiple spatial layers to the same receiving device, and multi-user MIMO (MU-MIMO) for transmitting multiple spatial layers to multiple devices.

[0080] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to shape or manipulate antenna beams (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array so that some signals propagating in some orientations relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals transmitted via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each 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).

[0081] 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 communications 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 (e.g., by a transmitting device such as the base station 105, or by a receiving device such as the UE 115) to identify a beam direction for transmission or reception to be performed later by the base station 105.

[0082] 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 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.

[0083] In some examples, transmission by a device (e.g., by a base station 105 or a UE 115) can be performed using multiple beam directions, and the device can 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 can report feedback indicating precoding weights for one or more beam directions, and the feedback can correspond to a configured number of beams across the system bandwidth or one or more subbands. The base station 105 can transmit a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)) that can be precoded or not. The UE 115 can provide feedback for beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel codebook, a linear combination codebook, a port selection codebook). Although these techniques are described with reference to signals transmitted in one or more directions by base station 105, UE 115 may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction 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).

[0084] A receiving device (e.g., UE 115) may try multiple reception configurations (e.g., directional detection) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiving device may try multiple reception directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets (e.g., different directional detection weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, wherein any of these operations may be referred to as "detection" according to different reception configurations or reception directions. In some examples, the receiving device may 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 detection according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio (SNR), or other acceptable signal quality based on detection according to multiple beam directions).

[0085] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication at the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly to communicate on a logical channel. The medium access control (MAC) layer may perform priority processing and multiplexing of logical channels to transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration, and maintenance of an RRC connection that supports radio bearers for user plane data between UE 115 and base station 105 or core network 130. At the physical layer, transport channels may be mapped to physical channels.

[0086] UE 115 and base station 105 can support retransmission of data to increase the possibility of successfully receiving data. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the possibility of correctly receiving data on communication link 125. HARQ can include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC) and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve the throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device can support simultaneous slot HARQ feedback, wherein the device can provide HARQ feedback in a specific time slot for data received in the previous symbol in the time slot. In other cases, the device can provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0087] In some cases, the UE 115 may receive an uplink grant from the base station 105, the uplink grant indicating scheduling information for uplink transmissions by the UE 115. For example, the uplink grant may indicate scheduling information including time and frequency resources for uplink transmissions (e.g., PUSCH transmissions). Similarly, the UE 115 may receive a downlink grant from the base station 105, the downlink grant indicating scheduling information for downlink transmissions from the base station 105 to the UE 115. For example, the downlink grant may indicate scheduling information including time and frequency resources for downlink transmissions (e.g., PDSCH transmissions). In some cases, the PDSCH may include downlink data and may also schedule uplink feedback transmissions (e.g., PUCCH transmissions) from the UE 115 to the base station 105 (e.g., where the PUCCH may include HARQ feedback associated with the PDSCH transmissions).

[0088] In some cases, the base station 105 may send an uplink grant to the UE 115 that indicates scheduling information for an uplink transmission (e.g., a PUSCH transmission) by the UE 115. In some scenarios, the base station 105 may also send a downlink grant that schedules feedback information (e.g., UCI) to be piggybacked on an uplink shared channel transmission. For example, in some cases, the uplink grant may schedule a PUSCH transmission that overlaps in time with a PUCCH transmission, such that the UE 115 may piggyback the UCI associated with the PUCCH transmission on the PUSCH transmission. The UE 115 may thus perform a PUSCH transmission to the base station (e.g., multiplexing the PUCCH feedback information on the PUSCH) and may discard the PUCCH transmission.

[0089] As discussed herein, the wireless communication system 100 may support simultaneous PUCCH-PUSCH transmissions of the UE 115. For example, the wireless communication system 100 may support and enable simultaneous PUCCH-PUSCH across two or more carriers. In some cases, in order to effectively support simultaneous PUCCH-PUSCH, the carrier configured for PUSCH transmission may be further configured to disable control information (e.g., the carrier configured for PUSCH in a simultaneous PUCCH-PUSCH scenario may be configured as a data-only carrier or a non-piggyback carrier). For example, the wireless communication system 100 may configure (e.g., via RRC signaling) simultaneous PUCCH-PUSCH across two or more carriers, where piggybacking of feedback information on uplink shared channel transmissions may be disabled. In other words, the wireless communication system 100 may configure simultaneous PUCCH-PUSCH such that feedback information (e.g., HARQ feedback, P-CSI) of the PUCCH may not be piggybacked (e.g., multiplexed) on the PUSCH (e.g., because the PUCCH and PUSCH may be transmitted simultaneously). Configuring UE 115 with simultaneous PUCCH-PUSCH and disabling UCI piggybacking on PUSCH for some uplink carriers may allow utilization of some SCells for data only, which may provide more efficient control information processing (e.g., improved HARQ processes), improved data throughput (e.g., on PUSCH), etc.

[0090] Figure 2 An example of a wireless communication system 200 that supports simultaneous PUCCH-PUSCH with different priorities according to aspects of the present disclosure is shown. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. The UE 115-a can be as described with respect to Figure 1 The example of UE 115 described above, and base station 105-a can be as described with respect to Figure 1 105 - a may serve a coverage area 110 - a, which may include a UE 115 - a. In some cases, the base station 105 - a and the UE 115 - a may communicate using various CA schemes. For example, the UE 115 - a may use an uplink CA configuration (e.g., which may include, for example, Figure 2 The wireless communication system 200 may communicate with the base station 105-a using two uplink carriers in the example shown. As discussed herein, the wireless communication system 200 may support simultaneous transmission of PUCCH transmissions 205 and PUSCH transmissions 210 (which may also be referred to as simultaneous PUCCH-PUSCH).

[0091] The base station 105-a may send an uplink grant 215 to the UE 115-a. The uplink grant 215 may schedule a set of uplink resources for the UE 115-a to use for sending an uplink transmission (e.g., a PUSCH transmission 210). In some cases, the UE 115-a may send a scheduling request (SR) to the base station 105-a prompting the base station 105-a to send the uplink grant 215 to the UE 115-a. For example, the UE 115-a may identify pending (e.g., buffered) data to be sent to the base station 105-a, and the UE 115-a may send the SR to the base station 105-a in response to request uplink resources for the transmission of the pending data. In response to the SR, the base station 105 - a may send an uplink grant 215 to the UE 115 - a , and the UE 115 - a may send uplink data (eg, a PUSCH transmission 210 ) to the base station 105 - a using the time and frequency resources indicated by the uplink grant 215 .

[0092] In some cases, the base station 105-a may send a downlink grant (which may also be referred to as a downlink allocation or scheduling allocation) to the UE 115-a. The downlink grant may include resources indicating a downlink transmission (e.g., a PDSCH message) from the base station 105-a. The UE 115-a may monitor the indicated resources for obtaining the PDSCH message and may attempt to decode the message. Based on the monitored resources and attempted decoding, the UE 115-a may generate feedback information for the PDSCH. The feedback information may be sent by the UE 115-a in an uplink message. For example, the UE 115-a may send HARQ feedback, such as an acknowledgment (ACK) or a negative acknowledgment (NACK). An ACK may be sent based on successful reception and decoding of a message from the base station 105-a, and a NACK may be sent based on failed reception or decoding of a PDSCH transmission. The feedback information may be sent in a PUCCH scheduled by an uplink grant sent by base station 105-a to UE 115-a (e.g., which may be included in the PDSCH, may be included in the original downlink grant, may be a separate uplink grant, etc.).

[0093] In some scenarios, UE 115-a may piggyback feedback information (e.g., ACK / NACK for downlink shared channel transmissions) in a PUSCH transmission 210. For example, in some cases, a PUCCH transmission 205 may be scheduled for a time that overlaps with a PUSCH transmission 210. Thus, UE 115-a may use PUSCH transmission 210 to send feedback information. For example, UE 115-a may piggyback UCI on a PUSCH transmission 210 (e.g., HARQ feedback, P-CSI, etc. may be multiplexed onto the PUSCH and may be sent via the PUSCH transmission 210), and UE 115-a may avoid sending the PUCCH. In other examples, UE 115-a may receive an uplink grant 215 that schedules a PUSCH transmission 210 that overlaps in time with a scheduled PUCCH transmission 205 (e.g., as Figure 2 ). In this case, UE 115-a may similarly piggyback (e.g., multiplex) UCI ​​associated with PUCCH transmission 205 onto PUSCH transmission 210 (e.g., and UE 115-a may drop PUCCH transmission 205 to avoid simultaneous PUCCH-PUSCH transmissions).

[0094] However, in some scenarios, a wireless communication system that supports simultaneous PUCCH-PUSCH transmissions may be beneficial. According to the techniques described herein, the wireless communication system 200 may support simultaneous PUCCH-PUSCH transmissions. For example, the wireless communication system 200 may support and enable simultaneous PUCCH-PUSCH across two or more carriers. In some cases, in order to effectively support simultaneous PUCCH-PUSCH, a carrier configured for PUSCH transmission 210 may also be configured to disable communication of PUCCH control information via the carrier (e.g., a carrier configured for PUSCH in a simultaneous PUCCH-PUSCH scenario may be configured as a data-only carrier). For example, the wireless communication system 200 may configure (e.g., via RRC signaling) simultaneous PUCCH-PUSCH across two or more carriers, wherein piggybacking feedback information on PUSCH transmission 210 may be disabled (e.g., and PUCCH transmission 205 may be sent simultaneously with PUSCH 210, or PUCCH transmission 205 may overlap at least partially in time with PUSCH 210). In other words, the wireless communication system 200 may configure simultaneous PUCCH-PUSCH so that feedback information (eg, HARQ feedback, P-CSI) of the PUCCH may not be piggybacked (eg, multiplexed) on the PUSCH.

[0095] In some examples, the wireless communication system 200 may illustrate inter-FR CA, inter-band CA, CA across carriers with different SCSs, CA in LAA systems, etc., wherein disabling UCI piggybacking on PUSCH for some uplink carriers of the CA configuration may provide more efficient communication. For example, in some cases, the CA configuration may include two carriers on different frequency bands or frequency ranges, may include two carriers with different SCSs, etc., so that multiplexing UCI may be computationally complex, may be time-consuming, may reduce network reliability and efficiency, etc. Therefore, disabling UCI piggybacking on carriers configured for PUSCH may provide reduced computational complexity, reduced latency (e.g., in some cases, UCI may be sent simultaneously via PUCCH transmission 205), etc.

[0096] As another example, in some cases, the CA configuration may include one or more carriers in an unlicensed band (e.g., in the example of an LAA system shown in the wireless communication system 200). In such a scenario, the UE 115-a may perform a listen-before-talk (LBT) procedure before accessing the medium. Therefore, reliance on UCI piggybacking for transmitting feedback information may be inefficient because the UE 115-a may or may not ultimately win access to the medium for PUSCH transmission 210 on a carrier in the unlicensed band. The described techniques may be implemented to disable UCI piggybacking on such carriers in an unlicensed band (e.g., which may provide improved reliability of uplink control information via PUSCH transmission 205, a data-only carrier that may provide throughput improvement via PUSCH transmission 210, and the like).

[0097] As described herein, simultaneous PUCCH-PUSCH may be configured via RRC signaling. For example, RRC configuration may enable simultaneous PUCCH-PUSCH across carriers, and, once configured for a particular PUSCH, multiplexing of UCI from the PUCCH may be disabled for the particular PUSCH configured for simultaneous PUCCH-PUSCH. In some cases, RRC signaling for simultaneous PUCCH-PUSCH configuration may include configuration of a data-only carrier on a per-carrier basis, per-uplink carrier group basis, per-cell group / PUCCH group basis, etc. (e.g., where UCI piggybacking is disabled).

[0098] For example, in some cases, a 1-bit RRC parameter for each uplink carrier may configure (e.g., may inform UE 115-a) which uplink carriers are configured as uplink data-only carriers (e.g., where an uplink data-only carrier may refer to an uplink carrier in which UCI piggybacking on PUSCH is disabled such that the PUSCH does not multiplex HARQ-ACK / P-CSI in the PUCCH). Once configured, UCI of the PUCCH will not be multiplexed on the PUSCH transmission 210 on the uplink carrier. For a supplementary uplink (SUL), a serving cell may have two uplink carriers (UL+SUL), in which case the 1-bit RRC parameter may be per UL / SUL carrier. For example, in a CA scenario where five uplink carriers are configured for uplink CA and two of the five carriers are configured with SUL, the RRC signaling may include a seven-bit sequence for per-uplink carrier configuration of whether these carriers are uplink data-only carriers (e.g., because a total of seven carriers may be configured as data-only carriers). For supplementary uplink (SUL), one serving cell may have two uplink carriers (UL+SUL), in which case the 1-bit RRC parameter may be per uplink serving cell (i.e., 1 bit per group of UL+SUL). As an example, in a CA scenario where five uplink carriers are configured for uplink CA and two of the five carriers are configured with SUL, the RRC signaling may include a five-bit sequence for per-uplink serving cell configuration of whether these carriers are uplink data-only carriers (e.g., because a total of five carriers may be configured as data-only carriers).

[0099] In some examples, a 1-bit RRC parameter for a group of uplink carriers may configure (e.g., inform UE 115-a) which group of uplink carriers is the uplink data-only carrier group. Once configured, the UCI of the PUCCH may not be multiplexed on any PUSCH transmission 210 in the UL carrier group indicated by the 1-bit RRC parameter. The group of uplink carriers may be per frequency band, per FR, per timing advance (TA) group, per cell group / PUCCH group, per UE 115, etc. In some cases, the signaling overhead for the configuration of uplink data-only carriers for simultaneous PUCCH-PUSCH configuration may be reduced.

[0100] In some examples, a 1-bit RRC parameter per cell group / PUCCH group may configure (e.g., inform UE 115-a) which SCells are uplink data-only carriers (e.g., those SCells in frequency bands other than that of the P(S)Cell / PUCCH-SCell in the cell group / PUCCH group). Once configured, UCI of the PUCCH may not be multiplexed on the PUSCH in any SCell that is in a different frequency band than the P(S)Cell / PUCCH-SCell. For example, in a CA scenario where five uplink carriers are configured in a cell group, if the RRC parameter corresponding to the cell group is set (e.g., converted, indicating a data-only configuration, etc.), one carrier is a PCell, one carrier is a SCell in the same frequency band as the PCell (e.g., and therefore it is not configured as data-only), and the remaining three carriers are in other frequency bands (e.g., and therefore the remaining three carriers are configured as data-only carriers). In other words, simultaneous PUCCH-PUSCH may be supported across multiple frequency bands (e.g., simultaneous PUCCH-PUSCH may not be supported within the same frequency band), and therefore, RRC signaling may accordingly configure simultaneous PUCCH-PUSCH across multiple frequency bands or across multiple frequency ranges on a cell-by-cell group basis.

[0101] In some examples, a 1-bit RRC parameter on a per-UE basis may configure (e.g., inform UE 115-a) which SCells are uplink data-only carriers (e.g., which SCells are in a frequency band other than that of the PCell). Once configured, UCI for the PUCCH may not be multiplexed on the PUSCH in any SCell that is in a different frequency band than the PCell. For example, in a CA scenario where five uplink carriers are configured in a cell group, if the RRC parameter corresponding to the cell group is set (e.g., converted, indicating a data-only configuration, etc.), one carrier is a PCell, one carrier is a SCell in the same frequency band as the PCell (e.g., and is therefore not configured as data-only), and the remaining three carriers are in other frequency bands (e.g., and the remaining three carriers are therefore configured as data-only carriers). In other words, simultaneous PUCCH-PUSCH may be supported across multiple frequency bands (e.g., simultaneous PUCCH-PUSCH may not be supported within the same frequency band), and therefore, RRC signaling may accordingly configure simultaneous PUCCH-PUSCH across multiple frequency bands or across multiple frequency ranges on a cell-by-cell group basis.

[0102] The wireless communication system 200 may process priority indications in accordance with one or more aspects of the techniques described herein. For example, an uplink grant 215 (e.g., a DCI for scheduling a PUSCH transmission 210) may include a priority index field to indicate a priority associated with a transmission or resource scheduled by the uplink grant 215. For example, the uplink grant 215 may include a priority index field to indicate a priority associated with a PUSCH transmission 210 scheduled by the uplink grant 215. In some cases, the UE 115-a may perform or discard overlapping scheduled transmissions based on any priority indication associated with the overlapping scheduled transmissions when simultaneous PUCCH-PUSCH is enabled (e.g., as described in more detail herein, e.g., with reference to Figures 3 to 6 ). Similarly, the base station 105-a can schedule transmissions, receive transmissions, set priorities for transmissions, etc. based on one or more aspects of the priority indication processing techniques described herein.

[0103] For example, the wireless communication system 200 (which in some examples may be an example of an ultra-reliable low latency communication (URLLC) system) may include a one-bit priority indication field in the downlink DCI and the uplink DCI. If multiple transmissions associated with different priority indices overlap, the UE 115-a may discard one or more transmissions with lower priority indices. For example, the wireless communication system 200 may process the priority indication in two steps. First, any overlapping PUSCH / PUCCH transmissions with the same priority index across multiple uplink carriers may be resolved (e.g., if the PUCCH and PUSCH associated with the same priority index overlap in time, the UCI on the PUCCH is piggybacked on the PUSCH and the PUCCH is discarded). Second, any overlapping PUSCH / PUCCH transmissions with different priority indices across multiple uplink carriers may be resolved. For example, Table 1 may illustrate priority processing in an example scenario where simultaneous PUCCH-PUSCH is not configured.

[0104] Table 1

[0105]

[0106] In scenarios where simultaneous PUCCH-PUSCH is configured, the techniques described herein may provide additional priority handling techniques because, in some cases, the configuration of simultaneous PUCCH-PUSCH may affect whether overlapping scheduled transmissions may be sent simultaneously or whether overlapping scheduled transmissions are to be discarded. In some examples, the wireless communication system 200 may not include a priority indication field in a DCI for scheduling PDSCH / PUSCH on any carrier configured for simultaneous PUCCH-PUSCH (e.g., the priority indication may be disabled on a carrier configured for simultaneous PUCCH-PUSCH, or on all carriers when simultaneous PUCCH-PUSCH is configured). In such an example, if UE 115-a, UE 115-a may not expect to be configured with a priority indication field in a DCI for scheduling PDSCH / PUSCH on any carrier configured for simultaneous PUCCH-PUSCH.

[0107] As another example, whenever a PUSCH on a data-only uplink carrier is scheduled, any overlapping PUCCH / PUSCH in other carriers may have the same priority index as the PUSCH on the data-only uplink carrier. In such an example, overlapping PUSCH / PUCCH transmissions with the same priority index across multiple uplink carriers may be resolved because the priority index is the same between the overlapping uplink transmissions. For example, refer to the following Figures 3 to 6 , various additional techniques for prioritizing overlapping scheduled transmissions are described herein.

[0108] In addition, in some cases, the wireless communication system 200 may specify or comply with criteria for when simultaneous PUCCH-PUSCH may be configured. For example, in some cases, simultaneous PUCCH-PUSCH may not be configured with two cell groups / PUCCH groups (e.g., to avoid simultaneous transmission of PUCCH+PUSCH+PUCCH+PUSCH across multiple uplink carriers, which may result in new UE behavior regarding power allocation across multiple uplink transmissions). In other examples, simultaneous PUCCH-PUSCH may be configured with two cell groups / PUCCH groups, however, the combination of UE transmissions may be restricted. For example, two PUCCHs, one PUCCH+one / multiple PUSCHs, two / multiple PUSCHs, etc. may be allowed (e.g., may be configured within the wireless communication system 200). However, two PUCCHs+one / multiple PUSCHs may not be allowed (e.g., may not be configured within the wireless communication system 200).

[0109] Figure 3An example of a simultaneous PUCCH-PUSCH transmission diagram 300 supporting simultaneous PUCCH-PUSCH with different priorities in accordance with aspects of the present disclosure is shown. In some examples, the simultaneous PUCCH-PUSCH transmission diagram 300 can implement aspects of the wireless communication system 100 and / or the wireless communication system 200. The simultaneous PUCCH-PUSCH transmission diagram 300 can illustrate a technique for simultaneous PUCCH-PUSCH priority handling (e.g., where simultaneous PUCCH-PUSCH transmissions are determined in step 1 before handling different priorities).

[0110] For example, when the UE is configured with a priority index field in the DCI, simultaneous PUCCH-PUSCH transmissions may be determined in step 1 before processing different priorities. In step 1, the UE may parse overlapping PUSCH / PUCCH transmissions with the same priority index across multiple UL carriers and may determine simultaneous PUCCH-PUSCH according to the procedures described herein. For a given priority index, simultaneous PUCCH-PUSCH may occur as a result of step 1. For example, in Figure 3 In the example of , as a result of step 1 for a low priority index, simultaneous transmission 305 and transmission 310 (e.g., simultaneous PUCCH-PUSCH) may occur. In step 2, the UE may compare the overlapping transmissions (e.g., simultaneous transmission 305 and transmission 310 overlapping with transmission 315), and the UE may select transmission 315 with a high priority (e.g., and the UE may discard transmission 305, transmission 310, or both). In general, Table 2 may illustrate priority handling in an example scenario where simultaneous PUCCH-PUSCH occurs as a result of step 1.

[0111] Table 2

[0112]

[0113] Figure 4 An example of a simultaneous PUCCH-PUSCH transmission diagram 400 supporting simultaneous PUCCH-PUSCH with different priorities in accordance with aspects of the present disclosure is shown. In some examples, the simultaneous PUCCH-PUSCH transmission diagram 400 can implement aspects of the wireless communication system 100 and / or the wireless communication system 200. The simultaneous PUCCH-PUSCH transmission diagram 400 can illustrate a technique for simultaneous PUCCH-PUSCH priority handling (e.g., where simultaneous PUCCH-PUSCH transmissions are determined in step 2 after parsing the PUCCH / PUSCH for each priority index).

[0114] For example, when the UE is configured with a priority index field in the DCI, simultaneous PUCCH-PUSCH transmissions may be determined in step 2 after parsing the PUCCH / PUSCH for each priority index. In step 1, the UE may parse overlapping PUSCH / PUCCH transmissions having the same priority index. For example, the UE may parse overlapping transmissions 405 and 410 (e.g., the UE may parse a transmission for a low priority index), where the HARQ-ACK for transmission 410 may be piggybacked on transmission 405. Thus, for a given priority index, simultaneous PUCCH-PUSCH may not occur as a result of step 1.

[0115] In step 2, PUCCH and PUSCH across multiple carriers with different priority indexes may be transmitted. For example, if a PUCCH with a first priority index and a PUSCH with a second priority index different from the first priority index occur, then the PUCCH and PUSCH may be transmitted simultaneously if they are on different carriers, or the PUCCH or PUSCH with a lower priority index may be dropped (e.g., not transmitted) if they are on the same carrier. Figure 4 In the example of FIG. 4 , as a result of step 2, transmission 405 and transmission 415 may be sent simultaneously.

[0116] Figure 5 An example of a simultaneous PUCCH-PUSCH transmission diagram 500 supporting simultaneous PUCCH-PUSCH with different priorities in accordance with aspects of the present disclosure is shown. In some examples, the simultaneous PUCCH-PUSCH transmission diagram 500 can implement aspects of the wireless communication system 100 and / or the wireless communication system 200. The simultaneous PUCCH-PUSCH transmission diagram 500 can illustrate a technique for simultaneous PUCCH-PUSCH priority handling (e.g., where PUCCH and PUSCH are transmitted simultaneously, regardless of the same priority or different priorities, as long as the PUCCH and PUSCH are in different frequency bands or in different frequency ranges).

[0117] For example, when the UE is configured with a priority index field in the DCI, regardless of the priority (e.g., regardless of whether the transmissions have the same priority or different priorities), PUCCH and PUSCH are sent simultaneously as long as PUCCH and PUSCH are in different frequency bands (e.g., or in different frequency ranges). If PUCCH and PUSCH are in the same frequency band (or in the same frequency range), a priority processing technique for discarding transmissions in the same frequency band may be employed (e.g., steps 1 and 2 may be performed for PUCCH and PUSCH in the same frequency band or the same frequency range). Figure 5 In the example of , in step 1, the UE may jointly check all PUCCH transmissions and PUSCH transmissions with different priorities, wherein transmission 510 may be discarded. In step 2, the UE may send PUCCH with high priority and PUSCH with low priority on the SCell as long as the two are in different frequency bands (e.g., the UE may send transmission 505 and transmission 515 simultaneously as long as the two are in different frequency bands).

[0118] Figure 6 An example of a process flow 600 for supporting simultaneous PUCCH-PUSCH with different priorities according to aspects of the present disclosure is shown. In some examples, the process flow 600 can implement aspects of the wireless communication system 100 and / or the wireless communication system 200. In addition, the process flow 600 can be implemented by the UE 115-b and the base station 105-b, which can be referenced Figure 1-2 1 and 105. In the following description of process flow 600, operations between UE 115-b and base station 105-b may be sent in an order different from that shown, or operations performed by base station 105-b and UE 115-b may be performed in a different order or at a different time. Specific operations may also be excluded from process flow 600, or other operations may be added to process flow 600. It should be understood that although base station 105-b and UE 115-b are shown performing multiple operations of process flow 600, any wireless device may perform the operations shown.

[0119] At 605, the base station 105-b may send RRC signaling to the UE 115-b. The RRC signaling may include feedback information piggybacking status for a first uplink carrier of a plurality of uplink carriers configured for the UE 115-b.

[0120] At 610, the base station 105-b may send a first uplink grant to the UE 115-b, the first uplink grant indicating a first uplink channel transmission opportunity and a first priority index for a first uplink transmission on a first uplink carrier.

[0121] At 615, the base station 105-b may send a second uplink grant to the UE 115-b, the second uplink grant indicating a second uplink channel transmission opportunity that at least partially overlaps in time with the first uplink channel transmission opportunity.

[0122] At 620, UE 115-b may perform priority processing, simultaneous PUCCH-PUSCH determination, etc. in accordance with one or more aspects of the techniques described herein. For example, in some cases, UE 115-b may identify priorities of a first uplink transmission and a second uplink transmission based on a first priority index and a second uplink channel transmission opportunity at least partially overlapping in time with the first uplink channel transmission opportunity, wherein the first uplink transmission, the second uplink transmission, or both are performed based on priority. In other words, whenever a PUSCH on a data-only uplink carrier is scheduled, any overlapping PUCCH / PUSCH in other carriers may have the same priority index as the PUSCH on the data-only uplink carrier.

[0123] In other examples, UE 115-b may receive a second uplink grant indicating a second uplink channel transmission opportunity and a second priority index for a second uplink transmission, wherein the first uplink transmission, the second uplink transmission, or both are performed at least in part based on the first priority index, the second priority index, and the feedback information piggybacking state. In other words, the uplink grants for overlapping transmissions may include the same or different priority indications in the DCI.

[0124] In some examples, UE 115-b may identify, based on the first uplink grant, an uplink control channel opportunity that at least partially overlaps in time with the first uplink channel transmission opportunity, and UE 115-b may perform or discard an uplink control transmission during the uplink control channel opportunity based on the first priority index, the second priority index, the feedback information piggybacking state, or some combination thereof (e.g., as described herein, for example, with reference to Figure 3In some cases, UE 115-b may discard the second uplink transmission based on the second priority index being associated with a priority lower than the first priority index, wherein the first uplink transmission and the uplink control transmission are performed based on discarding the second uplink transmission. In other cases, UE 115-b may discard the first uplink transmission, the uplink control transmission, or both based on the first priority index being associated with a priority lower than the second priority index, wherein the second uplink transmission is performed based on discarding the first uplink transmission, the uplink control transmission, or both (e.g., as described herein, for example with reference to Figure 3 Step 2 is described in detail).

[0125] In some examples, UE 115-b may identify, based on the second uplink grant, a second uplink control channel opportunity that at least partially overlaps in time with a second uplink channel transmission opportunity, and UE 115-b may determine, based on the second uplink grant, that the second uplink transmission is associated with a second uplink carrier, wherein the second uplink carrier is different from the first uplink carrier, and wherein the first uplink transmission and the second uplink transmission are performed based on a feedback information piggybacking state for the first uplink carrier and the second uplink carrier is different from the first uplink carrier (e.g., as described herein, for example, with reference to Figure 4 Step 2 is described in detail).

[0126] In some examples, UE 115-b may determine that a first uplink transmission is associated with a first frequency band and an uplink control transmission is associated with a second frequency band, wherein the first uplink transmission and the uplink control transmission are performed based on a first frequency band that is different from the second frequency band (e.g., as described herein, for example, with reference to Figure 5 Various other examples of possible simultaneous PUCCH-PUSCH prioritization techniques at 620 are described throughout this disclosure.

[0127] At 625, UE 115-b may perform a first uplink transmission on the first uplink carrier during a first uplink channel transmission opportunity, a second uplink transmission during a second uplink channel transmission opportunity, or both based on the simultaneous PUCCH-PUSCH priority handling technique at 620 (e.g., based at least in part on the feedback information piggybacking state for the first uplink carrier and the first priority index). According to various examples described herein, in general, the first uplink channel transmission may refer to a PUSCH transmission, a PUCCH transmission, etc., and the second uplink transmission may refer to a PUSCH transmission, a PUCCH transmission, etc.

[0128] Figure 7 A block diagram 700 of a device 705 supporting simultaneous PUCCH-PUSCH with different priorities according to aspects of the present disclosure is shown. The device 705 may be an example of aspects of a UE 115 as described herein. The device 705 may include a receiver 710, a communication manager 715, and a transmitter 720. The device 705 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0129] The receiver 710 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channel information, data channel information, and information related to simultaneous PUCCH-PUSCH with different priorities, etc.). The information may be passed to other components of the device 705. The receiver 710 may be a reference Fig.10 Examples of various aspects of the transceiver 1020 are described. The receiver 710 may utilize a single antenna or a group of antennas.

[0130] The communication manager 715 may: receive a feedback information piggybacking status for a first uplink carrier in a set of uplink carriers configured for the UE; receive a first uplink grant indicating a first uplink channel transmission opportunity and a first priority index for a first uplink transmission on the first uplink carrier; receive a second uplink grant indicating a second uplink channel transmission opportunity that overlaps at least partially in time with the first uplink channel transmission opportunity; and perform a first uplink transmission on the first uplink carrier during the first uplink channel transmission opportunity, a second uplink transmission during the second uplink channel transmission opportunity, or both based on the feedback information piggybacking status and the first priority index for the first uplink carrier. The communication manager 715 may be an example of aspects of the communication manager 1010 described herein.

[0131] The communication manager 715 may implement one or more aspects of the techniques described herein to achieve improved handling of control information (e.g., improved HARQ processes), improved data throughput (e.g., on PUSCH), etc. For example, the communication manager 715 may receive feedback information piggyback status for a first uplink carrier and may more efficiently use the first uplink carrier for a data-only PUSCH, which may improve data throughput for the communication manager 715. Furthermore, the communication manager 715 may implement one or more aspects of the techniques described herein to achieve efficient handling of priority indications associated with scheduled transmissions that overlap when supporting simultaneous PUCCH-PUSCH (e.g., such that the communication manager 715 may efficiently configure or drop scheduled transmissions to achieve improved performance of communications by the device 705). Such improved performance may include improved reliability and signaling efficiency, resulting in improved throughput, reduced power consumption, and reduced signaling complexity.

[0132] The communication manager 715 or its subcomponents may be implemented in hardware, in code (e.g., software or firmware) executed by a processor, or any combination thereof. If implemented in code executed by a processor, the functions of the communication manager 715 or its subcomponents may be performed by a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described in this disclosure.

[0133] The communication manager 715 or its subcomponents can be physically located in different locations, including being distributed so that various parts of the functions are implemented by one or more physical components in different physical locations. In some examples, the communication manager 715 or its subcomponents can be separate and different components according to various aspects of the present disclosure. In some examples, according to various aspects of the present disclosure, the communication manager 715 or its subcomponents can be combined with one or more other hardware components, including but not limited to input / output (I / O) components, transceivers, network servers, another computing device, one or more other components described in the present disclosure, or combinations thereof.

[0134] The transmitter 720 can transmit signals generated by other components of the device 705. In some examples, the transmitter 720 can be collocated with the receiver 710 in the transceiver module. For example, the transmitter 720 can be a reference Fig.10 Examples of various aspects of the transceiver 1020 are described. The transmitter 720 may utilize a single antenna or a group of antennas.

[0135] Figure 8A block diagram 800 of a device 805 supporting simultaneous PUCCH-PUSCH with different priorities according to aspects of the present disclosure is shown. The device 805 may be an example of aspects of the device 705 or UE 115 as described herein. The device 805 may include a receiver 810, a communication manager 815, and a transmitter 835. The device 805 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0136] The receiver 810 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channel information, data channel information, and information related to simultaneous PUCCH-PUSCH with different priorities, etc.). The information may be passed to other components of the device 805. The receiver 810 may be a reference Fig.10 Examples of various aspects of the transceiver 1020 are described. The receiver 810 may utilize a single antenna or a group of antennas.

[0137] Communications manager 815 may be an example of aspects of communications manager 715 as described herein. Communications manager 815 may include carrier configuration manager 820, uplink grant manager 825, and transmission manager 830. Communications manager 815 may be an example of aspects of communications manager 1010 as described herein.

[0138] The carrier configuration manager 820 may receive feedback information piggybacking status for a first uplink carrier in a set of uplink carriers configured for the UE.

[0139] The uplink grant manager 825 may: receive a first uplink grant indicating a first uplink channel transmission opportunity and a first priority index for a first uplink transmission on a first uplink carrier; and receive a second uplink grant indicating a second uplink channel transmission opportunity that at least partially overlaps in time with the first uplink channel transmission opportunity.

[0140] The transmission manager 830 may perform a first uplink transmission on the first uplink carrier during a first uplink channel transmission opportunity, a second uplink transmission during a second uplink channel transmission opportunity, or both based on the feedback information piggybacking status and the first priority index for the first uplink carrier.

[0141] The transmitter 835 can transmit signals generated by other components of the device 805. In some examples, the transmitter 835 can be collocated with the receiver 810 in the transceiver module. For example, the transmitter 835 can be a reference Fig.10Examples of various aspects of the transceiver 1020 are described. The transmitter 835 may utilize a single antenna or a group of antennas.

[0142] Fig. 9 A block diagram 900 of a communication manager 905 supporting simultaneous PUCCH-PUSCH with different priorities in accordance with aspects of the present disclosure is shown. The communication manager 905 may be an example of aspects of the communication manager 715, the communication manager 815, or the communication manager 1010 described herein. The communication manager 905 may include a carrier configuration manager 910, an uplink grant manager 915, a transmission manager 920, a transmission priority manager 925, a PUCCH manager 930, and a frequency band manager 935. Each of these modules may communicate with each other directly or indirectly (e.g., via one or more buses).

[0143] The carrier configuration manager 910 may receive feedback information piggybacking status for a first uplink carrier in a set of uplink carriers configured for the UE.

[0144] The uplink grant manager 915 may receive a first uplink grant indicating a first uplink channel transmission opportunity and a first priority index for a first uplink transmission on a first uplink carrier.

[0145] In some examples, uplink grant manager 915 may receive a second uplink grant indicating a second uplink channel transmission opportunity that at least partially overlaps in time with the first uplink channel transmission opportunity.

[0146] The transmission manager 920 may perform a first uplink transmission on the first uplink carrier during a first uplink channel transmission opportunity, a second uplink transmission during a second uplink channel transmission opportunity, or both based on the feedback information piggybacking state for the first uplink carrier and the first priority index.
