Technical Field
[0003] The following relates to wireless communications, including feedback schemes for multi-component carrier scheduling and joint feedback reporting. Background Art
[0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcasting, etc. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems that may be referred to as new radio (NR) systems. These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread spectrum orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node supporting communication for multiple communication devices (which may also be referred to as user equipment (UE)) simultaneously.
[0005] A UE may be scheduled for data communication in one or more component carriers by one or more downlink control information (DCI) instances.Some techniques for providing feedback when a UE is scheduled in a multi-component carrier or cross-component carrier scheme may be improved. Summary of the invention
[0006] The described technology relates to improved methods, systems, devices, and apparatuses for supporting feedback schemes for multi-component carrier scheduling and joint feedback reporting. A user equipment (UE) may receive two downlink control information (DCI) in one physical downlink control channel (PDCCH) monitoring opportunity (PMO), each DCI scheduling the UE for different physical downlink shared channel (PDSCH) resources on the same component carrier. In some examples, the UE may receive one DCI that schedules two PDSCHs in different component carriers. In some cases, the UE may be scheduled according to these two examples at the same time. For example, the UE may receive at least two DCIs in a PMO, wherein the first DCI schedules the UE for a first PDSCH resource on a first component carrier and a second PDSCH resource on a second component carrier, and the second DCI schedules the UE for a third PDSCH resource on the first component carrier or the second component carrier. The technology described herein supports generating feedback for scheduling techniques, wherein during the PMO, the UE is scheduled by a single DCI for PDSCH resources on multiple component carriers, and during the PMO, the UE is scheduled for multiple PDSCH resources on a single component carrier.
[0007] Additional techniques are described herein to support providing joint feedback for multiple PDSCH resources corresponding to different control resource sets (CORESET) pool indices. Multiple PDSCH resources for different CORESET pool indices may be scheduled for the same component carrier during the same PMO. The UE may generate a hybrid automatic repeat request (HARQ) acknowledgement (ACK) codebook for PDSCH resources corresponding to different CORESET pool indices and report feedback on an uplink control channel. In some examples, different CORESET pool indices may correspond to different transmit receive points (TRPs).

[0078] A user equipment (UE) may communicate with a base station on multiple component carriers. The base station may send downlink control information (DCI) to schedule the UE for physical downlink shared channel (PDSCH) resources on one or more component carriers for data transmission to the UE. The DCI may be sent to the UE during a physical downlink control channel (PDCCH) monitoring opportunity (PMO), and the base station may send one or more DCIs in one or more component carriers of each PMO to schedule the UE for one or more PDSCH resources. In some cases, the UE may be configured to report hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback for multiple PDSCH resources. For example, the UE may generate a HARQ ACK codebook, where the index of the codebook corresponds to ACK or negative ACK (NACK) feedback for the scheduled PDSCH resources. The ordering of the codebook may be based on a downlink allocation indicator (DAI) value, which may be indicated by or correspond to a DCI for scheduling PDSCH resources. The value of the DAI field in the DCI may indicate the cumulative number of serving cell and PMO pairs in which PDSCH reception exists and up to the current serving cell and the current PMO. The DAI may first be incremented in ascending order of the serving cell index and then in ascending order of the PMO index.
[0079] The UE described herein may support a variety of different techniques for PDSCH resource scheduling. In some examples, the UE may receive two DCIs in one PMO, each DCI scheduling the UE for different PDSCH resources on the same component carrier. In some examples, the UE may receive one DCI that schedules two PDSCHs in different component carriers. In some cases, the UE may be scheduled according to these two examples at the same time. For example, the UE may receive at least two DCIs in a PMO, wherein the first DCI schedules the UE for a first PDSCH resource on a first component carrier and a second PDSCH resource on a second component carrier, and the second DCI schedules the UE for a third PDSCH resource on the first component carrier or the second component carrier. The techniques described herein support generating feedback for scheduling techniques, wherein during a PMO, the UE is scheduled by a single DCI for PDSCH resources on multiple component carriers, and during a PMO, the UE is scheduled for multiple PDSCH resources on a single component carrier.
[0080] Additional techniques are described herein to support providing joint feedback for multiple PDSCH resources corresponding to different control resource sets (CORESET) pool indices. Multiple PDSCH resources for different CORESET pool indices may be scheduled for the same component carrier during the same PMO. The UE may generate a HARQ ACK codebook for PDSCH resources corresponding to different CORESET pool indices and report feedback on an uplink control channel. In some examples, different CORESET pool indices may correspond to different transmit receive points (TRPs). The described techniques may enable the UE to send HARQ ACK feedback with improved efficiency and reduced processing cost, among other benefits.
[0081] Various aspects of the present disclosure are first described in the context of a wireless communication system. Various aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow charts related to a feedback scheme for multi-component carrier scheduling and joint feedback reporting.
[0082] Figure 1 An example of a wireless communication system 100 supporting a feedback scheme for multi-component carrier scheduling and joint feedback reporting in accordance with aspects of the present disclosure is shown. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low-latency communications, communications with low-cost and low-complexity devices, or any combination thereof.
[0083] 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 may support communication of signals according to one or more radio access technologies.
[0084] UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. UEs 115 may be devices of different forms or with different capabilities. Figure 1Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as Figure 1 shown.
[0085] The base stations 105 may communicate with the core network 130, with each other, or both. For example, the base stations 105 may interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate with each other via the backhaul links 120 (e.g., via X2, Xn, or other interfaces) directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130), or both. In some examples, the backhaul links 120 may be or may include one or more wireless links.
[0086] One or more of the base stations 105 described herein may include or may be referred to by those skilled in the art as a base station transceiver, a radio base station, an access point, a radio transceiver, a Node B, an eNodeB (eNB), a next generation Node B or a Gigabit Node B (any of which may be referred to as a gNB), a Home Node B, a Home eNodeB, or other suitable terminology.
[0087] 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 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 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, vehicles, meters, etc.
[0088] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network devices, including, for example, Figure 1 The macro eNB or gNB, small cell eNB or gNB, or relay base station, etc. are shown.
[0089] UE 115 and base station 105 can communicate with each other wirelessly via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a collection of radio frequency spectrum resources with a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of a radio frequency spectrum band (e.g., bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel can 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 can use carrier aggregation or multi-carrier operation to support communication with UE 115. UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers according to the carrier aggregation configuration. Carrier aggregation can be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers.
[0090] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling to coordinate 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 positioned according to a channel grid for discovery by a UE 115. A carrier may operate in a standalone mode, in which a UE 115 may perform initial acquisition and connection via the carrier, or in a non-standalone mode, in which a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.
[0091] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry both downlink communications and uplink communications (e.g., in TDD mode).
[0092] A carrier may be associated with a particular bandwidth of a radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a plurality of determined bandwidths of a carrier of 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 configured 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 a plurality of carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion of the carrier bandwidth (e.g., a subband, a BWP) or the entire carrier bandwidth.
[0093] The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource unit 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 related. The number of bits carried by each resource unit 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 units received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 may be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may also increase the data rate or data integrity used to communicate with UE 115.
[0094] 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 for a UE 115 may be limited to one or more active BWPs.
[0095] The time interval of the base station 105 or the UE 115 may be expressed as a multiple of a basic time unit, where the basic time unit may be, for example, T s =1 / (Δf max ·N f ) seconds sampling period, where Δf maxIt can represent the maximum subcarrier spacing supported, and N f The maximum supported discrete Fourier transform (DFT) size may be indicated. 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).
[0096] 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 (e.g., in the time domain) subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix preceding each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.
[0097] A subframe, slot, mini-slot, 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 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).
[0098] Physical channels may be multiplexed on a carrier according to various techniques. For example, physical control channels and physical data channels may be multiplexed on a downlink carrier 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., CORESET) for a physical control channel may be defined by a number of symbol periods and may extend across a system bandwidth of a carrier or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESET) may be configured for a set of UEs 115. For example, one or more UEs 115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates arranged in a cascaded manner in one or more aggregation levels. The aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coding information for a control information format having 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.
[0099] Each base station 105 can provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" refers to a logical communication entity used to communicate with the base station 105 (e.g., via a carrier), and can be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) used to distinguish adjacent cells. In some examples, a cell may also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) on which the logical communication entity operates. Such a cell can range from a smaller area (e.g., a structure, a subset of a structure) to a larger area, depending on various factors (e.g., the capabilities of the base station 105). For example, a cell may be or may include a building, a subset of a building, or an external space between or overlapping geographic coverage areas 110, and the like.
[0100] A macro cell 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 to a network provider that supports the macro cell. Compared to a macro cell, a small cell may be associated with a low-power base station 105, and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to a UE 115 that has a service subscription to a network provider, or may provide restricted access to a UE 115 associated with a small cell (e.g., a UE 115 in a closed subscriber group (CSG), a UE 115 associated with a user in a home or office). A base station 105 may support one or more cells, and may also use one or more component carriers to support communications on one or more cells.
[0101] 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.
[0102] In some examples, 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.
[0103] 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 105 may not be aligned in time in some examples. The techniques described herein may be used for synchronous operation or asynchronous operation.
[0104] Some UEs 115 (such as MTC or IoT devices) may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication 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 that integrate sensors or meters for measuring or capturing information and passing the information to a central server or application, which 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 business charging.
[0105] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception, but not simultaneously). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for UEs 115 include entering a power saving deep sleep mode when not engaged in active communications, operating over a limited bandwidth (e.g., in accordance with 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 subcarrier or resource block (RB) set) within a carrier, within a guard band of a carrier, or outside of a carrier.
[0106] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE115 can be designed to support ultra-reliable, low-latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication or group communication, and can be supported by one or more mission-critical services (e.g., mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData)). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency can be used interchangeably in this article.
[0107] In some examples, the UE 115 is also able to communicate directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be located outside the geographic coverage area 110 of the base station 105, or may be unable to receive transmissions from the base station 105 for other reasons. In some examples, a group of UEs 115 communicating via D2D communication may use a 1-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 the scheduling of resources for D2D communication. In other cases, D2D communication is performed between the UEs 115 without the involvement of the base station 105.
[0108] In some systems, the D2D communication link 135 can be an example of a communication channel (e.g., a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. 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 (e.g., roadside units), or communicate with a network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or communicate with both.
[0109] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connection, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnections to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by a base station 105 associated with the core network 130. User IP packets may be transmitted through a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to a network operator IP service 150. The operator IP service 150 may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.
[0110] Some network devices (e.g., 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 UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or 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 ANC) or merged into a single network device (e.g., base station 105).
[0111] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, yet the waves may penetrate structures sufficiently for a macro cell to provide service to a UE 115 located indoors. Transmissions using UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) than transmissions using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.
[0112] The wireless communication system 100 may also operate in a super high frequency (SHF) region using a frequency band of 3 GHz to 30 GHz (also referred to as a centimeter band), or in an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz), which is also referred to as a millimeter band. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and base station 105, and the EHF antennas of each device may be smaller and more closely spaced than UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may suffer from greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein may be applied across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary from country to country or administrative body.
[0113] The wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 can employ license assisted access (LAA) or LTE unlicensed (LTE-U) radio access technology or NR technology in an unlicensed band such as the 5 GHz industrial, scientific and medical (ISM) band. When operating in an unlicensed radio frequency 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 (e.g., LAA) in combination with component carriers operating in a licensed band. Operations in an unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.
[0114] The base station 105 or UE 115 may be equipped with multiple antennas, which may be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit beamforming or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having antenna ports of several rows and columns that the base station 105 may use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals sent via the antenna ports.
[0115] The base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technology may be referred to as spatial multiplexing. For example, the multiple signals may be sent by a transmitting device via different antennas or different antenna combinations. Similarly, the multiple signals may be received by a receiving device via different antennas or different antenna combinations. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) in which multiple spatial layers are sent to the same receiving device, and multi-user MIMO (MU-MIMO) in which multiple spatial layers are sent to multiple devices.
[0116] 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 an antenna beam or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array so that some signals propagating in a particular direction relative to the antenna array experience constructive interference while other signals experience destructive interference. Adjustments to signals transmitted via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).
[0117] 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. The base station 105 may send some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, the base station 105 may send signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used to identify (e.g., by a transmitting device such as the base station 105, or by a receiving device such as the UE 115) the beam direction for later transmission or reception by the base station 105.
[0118] Some signals, such as data signals associated with a particular receiving device, may be sent 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, the beam direction associated with transmissions along a single beam direction may be determined based on signals that have been sent in one or more beam directions. For example, UE 115 may receive one or more of the signals sent by base station 105 in different directions, and UE 115 may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or an acceptable signal quality.
[0119] In some examples, transmissions by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may 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 the system bandwidth or one or more subbands. The base station 105 may send a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel codebook, a linear combination codebook, a port selection codebook). Although these techniques are described with reference to signals sent by base station 105 in one or more directions, UE 115 may employ similar techniques for sending signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by UE 115), or for sending signals in a single direction (e.g., for sending data to a receiving device).
[0120] A receiving device (e.g., UE 115) may try multiple reception configurations (e.g., directional listening) when receiving various signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) from a base station 105. For example, a 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 listening 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, any of which may be referred to as "listening" according to different reception configurations or reception directions. In some examples, a receiving device may use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). A single reception configuration may be aligned on a beam direction determined based on listening according to different reception 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 listening according to multiple beam directions).
[0121] 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 multiplex logical channels into 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.
[0122] UE 115 and base station 105 may support retransmission of data to increase the likelihood of successfully receiving the data. HARQ feedback is a technique for increasing the likelihood of correctly receiving data via communication link 125. HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve the throughput of the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support same-slot HARQ feedback, wherein the device may provide HARQ feedback in a particular time slot for data received in a previous symbol in the time slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.
[0123] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, etc. These systems can be multiple access systems that can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). A wireless network, such as a wireless local area network (WLAN) (such as a Wi-Fi (i.e., an Institute of Electrical and Electronics Engineers (IEEE) 802.11) network), can include an access point (AP) that can communicate with one or more wireless devices or mobile devices. The AP can be coupled to a network (such as the Internet) and can enable mobile devices to communicate via the network (or communicate with other devices coupled to the access point). A wireless device can communicate bidirectionally with a network device. For example, in a WLAN, a device can communicate with an associated AP via a downlink (e.g., a communication link from an AP to a device) and an uplink (e.g., a communication link from a device to an AP). A wireless personal area network (PAN) (which can include a Bluetooth connection) can provide a short-range wireless connection between two or more paired wireless devices. For example, a wireless device (e.g., a cellular phone) can utilize wireless PAN communication to exchange information (e.g., audio signals) with a wireless headset.
[0124] UE 115 may receive two DCIs in one PMO, each DCI scheduling UE 115 for different PDSCH resources on the same component carrier. In some examples, UE 115 may receive one DCI scheduling two PDSCHs in different component carriers. In some cases, UE 115 may be scheduled according to both examples simultaneously. For example, UE 115 may receive at least two DCIs in a PMO, wherein a first DCI schedules UE 115 for a first PDSCH resource on a first component carrier and a second PDSCH resource on a second component carrier, and a second DCI schedules UE 115 for a third PDSCH resource on either the first component carrier or the second component carrier. The techniques described herein support generating feedback for scheduling techniques, wherein during a PMO, UE 115 is scheduled by a single DCI for PDSCH resources on multiple component carriers, and during the PMO, UE 115 is scheduled for multiple PDSCH resources on a single component carrier.
[0125] Additional techniques are described herein to support providing joint feedback for multiple PDSCH resources corresponding to different CORESET pool indices. Multiple PDSCH resources for different CORESET pool indices may be scheduled for the same component carrier during the same PMO. UE 115 may generate a HARQ ACK codebook for PDSCH resources corresponding to different CORESET pool indices and report feedback on an uplink control channel. In some examples, different CORESET pool indices may correspond to different TRPs.
[0126] Figure 2 An example of a wireless communication system 200 that supports a feedback scheme for multi-component carrier scheduling and joint feedback reporting according to aspects of the present disclosure is shown. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. The wireless communication system 200 can include a base station 105-a and a UE 115-a, which can be reference Figure 1 Corresponding examples of UE 115 and base station 105 are described.
[0127] The UE 115-a may communicate with the base station 105-a on a set 205 of component carriers 210. The base station 105-a may send a DCI 215 to schedule the UE 115-a for PDSCH resources 220 on one or more component carriers 210 for data transmission to the UE 115-a. The DCI 215 may be sent to the UE 115-a during a PMO 230, and the UE 115-a may monitor the CORESET in the PMO 230 to receive the DCI 215. In some cases, the base station 105-a may send one or more DCIs 215 on one or more component carriers 210 per PMO 230 to schedule the UE 115-a for one or more PDSCH resources 220. In some cases, the UE 115-a may be configured to report HARQ ACK feedback for multiple PDSCH resources 220 on a physical uplink control channel (PUCCH) resource 225. In some cases, the UE 115-a may be configured to report HARQ ACK feedback for each scheduled PDSCH resource 220 in one HARQ ACK codebook on the PUCCH resource 225. For example, the UE 115-a may generate a HARQ ACK codebook where an index of the codebook corresponds to ACK / NACK feedback for the scheduled PDSCH resource 220.
[0128] The ordering of the codebook may be based on a DAI value, which may be indicated by or correspond to a DCI 215 that schedules a PDSCH resource 220. The value of the counter DAI field in the DCI format may represent the cumulative number of pairs of serving cells and PMOs in which there is a semi-persistent scheduling (SPS) PDSCH release or PDSCH reception associated with the DCI format as of the current serving cell and the current PMO. The DAI may first be incremented in ascending order of the serving cell index and then in ascending order of the PMO index. In some cases, a serving cell may refer to a scheduled cell (e.g., a component carrier 210 on which a PDSCH resource 220 is scheduled) rather than a scheduling cell (e.g., a component carrier 210 on which a DCI 215 is received).
[0129] In an example, UE 115-a may receive DCI 215-a and DCI 215-b in a first PMO 230-a and DCI 215-c, 215-d, and 215-e in a second PMO 230-b. Component carrier 210-a and component carrier 210-b may be configured with self-scheduling, and component carrier 210-c may be configured with cross-carrier scheduling (e.g., from component carrier 210-a). Each DCI 215 may schedule PDSCH resources 220, and a value of a counter DAI may be indicated in each DCI 215.
[0130] As described above, the DAIs may be arranged first in ascending order of the serving cell index and then in ascending order of the PMO. DCI 215-a and DCI 215-b may appear in PMO 230-a, PMO 230-a having an earlier PMO index than PMO 230-b, so DCI 215-a and DCI 215-b may be sorted first, before DCI 215-c, 215-d, and 215-e. DCI 215-a may schedule PDSCH resources 220-a on component carrier 210-b, and DCI 215-b may schedule PDSCH resources 220-b on component carrier 210-c. In ascending order of the component carriers, DCI 215-a may correspond to or indicate a first DAI index, and DCI 215-b may correspond to a second DAI index. For PMO 230-b, DCI 215-c may schedule PDSCH resources 220-c on component carrier 210-a, DCI 215-d may schedule PDSCH resources 220-d on component carrier 210-b, and DCI 215-e may schedule PDSCH resources 220-e on component carrier 210-c. According to the component carrier sorting, DCI 215-c may correspond to the third DAI index, DCI 215-d may correspond to the fourth DAI index, and DCI 215-e may correspond to the fifth DAI index.
[0131] UE 115-a may construct a HARQ ACK codebook corresponding to PDSCH resource 220 based on the counter DAI value. For example, the first index in the codebook may include HARQ ACK feedback for PDSCH resource 220-a, the second index in the codebook may include HARQ ACK feedback for PDSCH resource 220-b, and so on. In some cases, there may be gaps or holes in the counter DAI value. For example, if UE 115-a does not receive or misses DCI 215-c, UE 115-a may determine that UE 115-a has never received DCI 215 corresponding to the third index, and UE 115-a may include the NACK in the corresponding index in the codebook. In some cases, the HARQ ACK codebook may be an example of a type 2 dynamic HARQ ACK codebook.
[0132] UE 115-a and other UEs 115 described herein may support a variety of different techniques for PDSCH resource scheduling. In some examples, UE 115-a may receive two DCIs 215 in one PMO 230, each DCI 215 scheduling UE 115-a for different PDSCH resources 220 on the same component carrier 210. In some cases, DAI sorting in the case where multiple DCIs in the same PMO schedule the same serving cell may be based on the PDSCH reception start time. For example, the DAIs may be sorted in the following manner: first based on the increasing order of the PDSCH reception start time of the same serving cell scheduled during the same PMO, then in ascending order of the serving cell index, and then in ascending order of the PMO index. For example, frequency range 1 (FR1) with 30kHz subcarrier spacing (SCS) can schedule frequency range 2 (FR2) with 120kHz SCS, because one time slot in FR1 can be equal to 4 time slots in FR2, and the scheduled component carrier in FR1 can schedule multiple PDSCH resources 220 through multiple DCIs 215 in the same PMO 230. In some cases, UE 115-a can indicate support for this scheduling by reporting UE capabilities (e.g., "PDSCH-Number-perMOperCell"). In some cases, UE 115-a can report the number of PDSCHs supported per cell per PMO,
[0133] In some examples, UE 115-a may receive one DCI 215 that schedules two PDSCH resources 220 in different component carriers 210. DCI 215 that schedules two PDSCH resources 220 may be referred to as a multi-component carrier scheduling DCI.
[0134] In some cases, the DAI ordering and numbering may be adjusted for a DCI 215 that schedules multiple PDSCH resources 220. In a first example, the counter DAI may be incremented by one value per DCI 215, even when the DCI 215 schedules two component carriers 210. However, the UE 115-a may generate two HARQ ACK bits for each DAI position in the codebook. If the DCI 215 schedules only one PDSCH resource 220, the second bit in the codebook corresponding to the DCI 215 may be a NACK. In a first example, the UE 115-a may identify an associated component carrier index for a DCI 215 that schedules multiple (e.g., two) component carriers 210, such that the DCI 215 is associated with one of the scheduled component carriers 210. For example, the UE 115-a may identify a larger component carrier index or a smaller component carrier index for the associated component carrier index.
[0135] For the DAI sorting in this first example, the counter DAI in the current DCI may represent the cumulative number of pairs of DCI and PMO in which there is an SPS PDSCH release or PDSCH reception associated with the DCI format as of the current DCI and the current PMO, first in ascending order of the serving cell index associated with the DCI in a given PMO, and then in ascending order of the PMO index. The HARQ ACK codebook may be generated based on the counter DAI definition and the counter DAI value of the received DCI.
[0136] In a second example of multi-component carrier scheduling DCI, the DCI 215 may indicate one DAI value for each scheduled PDSCH resource 220. For example, if the DCI 215 schedules two PDSCH resources 220, the DCI may indicate two DAI values, one for each scheduled PDSCH resource 220.
[0137] In some cases, the UE 115-a may be scheduled according to both examples simultaneously. For example, the UE 115-a may receive at least two DCIs 215 in a PMO 230, wherein the first DCI 215 schedules the UE 115-a for a first PDSCH resource 220 on a first component carrier 210 and a second PDSCH resource 220 on a second component carrier 210, and the second DCI 215 schedules the UE 115-a for a third PDSCH resource 220 on either the first component carrier 210 or the second component carrier 210. Techniques described herein support generating feedback for a case where, during a PMO, the UE 115 is scheduled by a single DCI 215 for PDSCH resources 220 on multiple component carriers 210, and during the PMO 230, the UE 115 is scheduled for multiple PDSCH resources 220 on a single component carrier 210.
[0138] Other examples are provided, or these techniques may be applied to other examples. For example, a UE 115 may receive two multi-component carrier scheduling DCIs 215 in the same PMO 230, both DCIs 215 scheduling the same component carrier 210. In some cases, there may be two multi-component carrier scheduling DCIs in the same PMO, wherein the first DCI 215 is for the first and second component carriers, and the second DCI 215 is for the first and third component carriers. In some cases, there may be a first DCI 215 scheduling a single component carrier 210 and a second DCI 215 scheduling multiple component carriers 210 in the same PMO 230, wherein the first DCI 215 schedules the first component carrier 210, and the second DCI 215 schedules the first component carrier 210 and the second component carrier 210. The UE 115 described herein may be able to provide HARQ ACK feedback (e.g., in a HARQ ACK codebook) for any of these scheduling examples, and the like.
[0139] Additional techniques are described herein to support providing joint feedback for multiple PDSCH resources 220 corresponding to different CORESET pool indices. Multiple PDSCH resources 220 for different CORESET pool indices may be scheduled for the same component carrier 210 during the same PMO 230. The UE may generate HARQ ACK codebooks for PDSCH resources 220 corresponding to different CORESET pool indices and report feedback on PUCCH resources 225. In some examples, different CORESET pool indices may correspond to different TRPs.
[0140] Figure 3An example of a scheduling scheme 300 supporting a feedback scheme for multi-component carrier scheduling and joint feedback reporting is shown in accordance with aspects of the present disclosure. In some examples, the scheduling scheme 300 can implement aspects of the wireless communication system 100.
[0141] Base station 105 may send DCI 315 to schedule UE 115 for PDSCH 320 on one or more component carriers 305. UE 115 may generate feedback for PDSCH 320 and send the feedback on PUCCH 325. UE 115 may generate a HARQ ACK codebook, where each index of the codebook corresponds to a DCI scheduling a PDSCH resource.
[0142] UE 115 may receive two DCIs 315 that schedule component carrier 305-c, and one of the DCIs 315 may schedule multiple component carriers 305. For example, UE 115 may receive DCI 315-a, DCI 315-b, and DCI 315-c during PMO 310. DCI 315-a may schedule PDSCH 320-a, DCI 315-b may schedule PDSCH 320-b and PDSCH 320-c, and DCI 315-c may schedule PDSCH 320-d.
[0143] In the example of scheduling scheme 300, counter DAI may be incremented by one value per DCI 315, even when DCI 315 schedules two component carriers 305. UE 115 may generate two bits for each DAI position in the codebook. If DCI 315 schedules only one PDSCH 320, the second bit of DCI 315 may be NACK.
[0144] The UE 115 may identify an associated component carrier index for each DCI 315. If the DCI 315 schedules one component carrier 305, the associated component carrier index may be the scheduled component carrier index. If the DCI 315 schedules two component carriers, the associated component carrier index may be one of the scheduled component carrier indices. In some cases, the associated component carrier index may correspond to a scheduled component carrier with a higher index or a lower index.
[0145] DCI 315-a may schedule PDSCH 320-a in component carrier 305-b, so the associated component carrier index may be "2" for DCI 315-a. DCI 315-b may schedule PDSCH 320-b and PDSCH 320-c, which may be in component carrier 305-a and component carrier 305-c, respectively. In the example of scheduling scheme 300, UE 115 may identify component carrier 305-c for the associated component carrier index, so for DCI 315-b, the associated component carrier index may be "3". DCI 315-c may schedule PDSCH 320-d on component carrier 305-c, so the associated component carrier index may also be "3" for DCI 315-c.
[0146] If two or more DCIs 315 have the same associated component carrier index in the same PMO, the values of the DAI may be arranged in ascending order of the PDSCH reception start time in the associated component carrier index. For example, PDSCH 320-b is received before PDSCH 320-d, so PDSCH 320-b may have a lower DAI value.
[0147] DCI 315-a may have a lower associated component carrier index of "2," so DCI 315-a may be associated with the first DAI. DCI 315-b and DCI 315-c may each have an associated component carrier index of "3," but PDSCH 320-b may be received before PDSCH 320-d, so DCI 315-b may have the second DAI and DCI 315-c may be associated with the third DAI.
[0148] UE 115 may generate a HARQ ACK codebook based on the DAI and send the codebook on PUCCH 325. A first index 330-a of the codebook may include two-bit HARQ ACK feedback for PDSCH 320-a, a second index 330-b of the codebook may include two-bit HARQ ACK feedback for PDSCH 320-b and PDSCH 320-c, and a third index 330-c of the codebook may include two-bit HARQ ACK feedback for PDSCH 320-d. The second bit of the HARQ ACK feedback for PDSCH 320-a and PDSCH 320-d may be NACK because the scheduling DCI 315 schedules only one PDSCH 320 each.
[0149] Figure 4An example of a scheduling scheme 400 supporting a feedback scheme for multi-component carrier scheduling and joint feedback reporting is shown in accordance with aspects of the present disclosure. In some examples, the scheduling scheme 400 can implement aspects of the wireless communication system 100.
[0150] Base station 105 may send DCI 415 to schedule UE 115 for PDSCH 420 on one or more component carriers 405. UE 115 may generate feedback for PDSCH 420 and send the feedback on PUCCH 425. UE 115 may generate a HARQ ACK codebook, where each index of the codebook corresponds to a DCI scheduling a PDSCH resource.
[0151] UE 115 may receive two DCIs 415 that schedule component carrier 405-c, and one of DCIs 415 may schedule multiple component carriers 405. For example, UE 115 may receive DCI 415-a, DCI 415-b, and DCI 415-c during PMO 410. DCI 415-a may schedule PDSCH 420-a, DCI 415-b may schedule PDSCH 420-b and PDSCH 420-c, and DCI 415-c may schedule PDSCH 420-d.
[0152] In the example of the scheduling scheme 400, the counter DAI may be incremented by one value per DCI 415, even when the DCI 415 schedules two component carriers 405. The UE 115 may generate two bits for each DAI position in the codebook. If the DCI 415 schedules two PDSCHs 420, each of the two bits may correspond to feedback for one of the two PDSCHs 420. If the DCI 415 schedules only one PDSCH 420, the second bit of the DCI 415 may be a NACK.
[0153] The UE 115 may identify an associated component carrier index for each DCI 415. If the DCI 415 schedules one component carrier 405, the associated component carrier index may be the scheduled component carrier index. If the DCI 415 schedules two component carriers, the associated component carrier index may be one of the scheduled component carrier indices. In some cases, the associated component carrier index may correspond to a scheduled component carrier with a higher index or a lower index.
[0154] DCI 415-a may schedule PDSCH 420-a in component carrier 405-b, so the associated component carrier index may be "2" for DCI 415-a. DCI 415-b may schedule PDSCH 420-b and PDSCH 420-c, which may be in component carrier 405-a and component carrier 405-c, respectively. In the example of scheduling scheme 400, UE 115 may identify component carrier 405-a for the associated component carrier index, so the associated component carrier index may be "1" for DCI 415-b. DCI 415-c may schedule PDSCH 420-d on component carrier 405-c, so the associated component carrier index may also be "3" for DCI 415-c. Each DCI 415 may have a different associated component carrier index, so DAI sorting may be based on the associated component carrier index. For example, DCI 415-b may have a first DAI, DCI 415-a may have a second DAI, and DCI 415-c may have a third DAI.
[0155] UE 115 may generate a HARQ ACK codebook based on the DAI and send the codebook on PUCCH 425. A first index 430-a of the codebook may include two-bit HARQ ACK feedback for PDSCH 420-b and PDSCH 420-c, a second index 430-b of the codebook may include two-bit HARQ ACK feedback for PDSCH 420-a, and a third index 430-c of the codebook may include two-bit HARQ ACK feedback for PDSCH 420-d. The second bit of the HARQ ACK feedback for PDSCH 420-a and PDSCH 420-d may be NACK because the scheduling DCI 415 schedules only one PDSCH 420 each.
[0156] Figure 5 An example of a scheduling scheme 500 supporting a feedback scheme for multi-component carrier scheduling and joint feedback reporting is shown in accordance with aspects of the present disclosure. In some examples, the scheduling scheme 500 can implement aspects of the wireless communication system 100.
[0157] Base station 105 may send DCI 515 to schedule UE 115 for PDSCH 520 on one or more component carriers 505. UE 115 may generate feedback for PDSCH 520 and send the feedback on PUCCH 525. UE 115 may generate a HARQ ACK codebook, where each index of the codebook corresponds to a DCI scheduling a PDSCH resource.
[0158] UE 115 may receive two DCIs 515 that schedule component carrier 505-a, and one of the DCIs 515 may schedule multiple component carriers 505. Additionally, UE 115 may receive two DCIs 515 that schedule component carrier 505-a, and one of the DCIs 515 may schedule multiple component carriers 505. For example, UE 115 may receive DCI 515-a, DCI 515-b, DCI 515-c, and DCI 515-d during PMO 510. DCI 515-a may schedule PDSCH 520-a and PDSCH 520-d, DCI 515-b may schedule PDSCH 520-b, DCI 515-c may schedule PDSCH 520-c, and DCI 515-d may schedule PDSCH 520-e.
[0159] In the example of scheduling scheme 500, DCI 515 that schedules two PDSCHs 520 in two component carriers 505 may indicate two DAI values corresponding to the two scheduled component carriers 505. For example, DCI 515-a may schedule PDSCH 520-a and PDSCH 520-d, and DCI 515-a may therefore indicate two DAI values.
[0160] If another DCI schedules at least one component carrier 505 of the two component carriers 505 that is scheduled by a multi-component carrier scheduling DCI, the value of the DAI can be based on which PDSCH has an earlier start time. For example, both DCI 515-a and DCI 515-b schedule component carrier 505-a, but PDSCH 520-a can be earlier than PDSCH 520-b. Therefore, one of the two DAIs corresponding to DCI 515-a that schedules PDSCH 520-a can be ranked in front of (e.g., before) the DAI corresponding to DCI 515-b that schedules PDSCH 520-b. Similarly, both DCI 515-a and DCI 515-d schedule component carrier 505-c, but PDSCH 520-d appears before PDSCH 520-e in the time domain. Therefore, the other of the two DAIs for DCI 515-a may be ranked before the DAI corresponding to DCI 515-d.
[0161] The first index 530-a of the codebook may correspond to DCI 515-a, which schedules PDSCH 520-a on component carrier 505-a. The second index 530-b may correspond to DCI 515-b, which is also scheduled on component carrier 505-a, but PDSCH 520-b occurs after PDSCH 520-a in the time domain. The next highest serving cell index corresponding to component carrier 505-b includes PDSCH 520-c scheduled by DCI 515-c. Therefore, the third index 530-c may correspond to DCI515-c. Component carrier 505-c includes PDSCH 520-d and PDSCH 520-e. The fourth index 530-d may correspond to DCI515-a because PDSCH 520-d appears before PDSCH 520-e in the time domain. The fifth index 530-e may correspond to DCI515-d. Each index 530 may include HARQ ACK feedback for the PDSCH 520 scheduled by the corresponding DCI 515. For example, the first index 530-a may include HARQ ACK feedback for the PDSCH 520-a.
[0162] Figure 6 An example of a joint feedback scheme 600 supporting feedback schemes for multi-component carrier scheduling and joint feedback reporting is shown in accordance with aspects of the present disclosure. In some examples, the joint feedback scheme 600 can implement aspects of the wireless communication system 100.
[0163] In some cases, the UE 115 may support joint feedback for transmissions from multiple TRPs. In some cases, different TRPs may have different CORESET pool index values. For example, a CORESET pool index may be configured for each CORESET, and the UE 115 may group the CORESETs into two groups corresponding to CORESET pool index values 0 and 1. For joint feedback, the DAIs may be sorted first in increasing order of CORESET pool index values in the same component carrier and the same PMO 610, second in increasing order of component carrier index, and third in increasing order of PMO index. For example, if UE 115 is not provided with a CORESET pool index for the active downlink bandwidth portion of the serving cell, or is provided with a CORESET pool index with a value of 0 for one or more first CORESETs, and UE 115 is provided with a CORESET pool index with a value of 1 for one or more second CORESETs, and UE 115 is configured for joint feedback, then for the same serving cell index and the same PMO610, the value of the counter DAI can be in the order of the first CORSET first and then the second CORSET.
[0164] For HARQ ACK codebook construction based on DAI value, each component carrier with two CORESET pool index values may be counted twice. The PDSCH 620 may be associated with the CORESET pool index value by the scheduling DCI 615. For example, if the scheduling DCI 615 is received in the first CORESET, the PDSCH 620 may be associated with the CORESET pool index value of 0; or if the scheduling DCI 615 is received in the second CORESET, the PDSCH 620 may be associated with the CORESET pool index value of 1. For example, if the UE 115 is not provided with a CORESET pool index for the active downlink bandwidth portion of the serving cell, or is provided with a CORESET pool index with a value of 0 for one or more first CORESETs, and the UE 115 is provided with a CORESET pool index with a value of 1 for one or more second CORESETs, and the UE 115 is configured for joint feedback, the serving cell may be counted twice, with the first time corresponding to the first group of CORSETs and the second time corresponding to the second group of CORSETs.
[0165] In some cases, the UE 115 may indicate support for multiple PDSCHs scheduled per cell per PMO. For example, the UE 115 may send a UE capability to the base station 105 indicating support for multiple PDSCHs scheduled for one component carrier during a single PMO. In some cases, the UE 115 may indicate support for "PDSCH-Number-perMOperCell" to the base station 105. In some cases, the UE 115 may indicate the number of PDSCHs 620 that the UE 115 can be scheduled per PMO 610 per component carrier 605, or
[0166] In the example of the joint feedback scheme 600, the UE 115 may not be provided with a CORESET pool index for an active downlink BWP of a serving cell, or the UE 115 may be provided with a CORESET pool index having a value of 0 for one or more first CORESETs. Additionally, the UE 115 may be provided with a CORESET pool index having a value of 1 for one or more second CORESETs. The UE 115 may receive DCI 615-a to DCI 615-d on component carrier 605-a during PMO 610, and DCI 615-e and DCI 615-f on component carrier 605-b. DCI 615-a, DCI 615-b, DCI 615-e, and DCI 615-f may be associated with a control resource pool index having a value of 0, and DCI 615-c and DCI 615-d may be associated with a CORESET pool index having a value of 1.
[0167] In the same PMO 610, there may be a total number of DCIs 615 that schedule the same component carrier 605 (e.g., component carriers 605 with two values of the CORESET pool index). In a first example, there may be up to twice as many DCIs as indicated by the UE capability. For example, the UE 115 may indicate support for "PDSCH-Number-perMOperCell", which may indicate the UE's ability to sort DAIs for the PDSCH start time for the same component carrier and the same PMO. Additionally or alternatively, the UE 115 may indicate the number of PDSCHs that can be scheduled for the same component carrier at the same PMO, which may be indicated by In the first example, for a component carrier 605 with two CORESET pool index values, there can be at most DCIs schedule the same component carrier 605. For example, the number indicated by UE capability signaling may correspond to the number of PDSCHs associated with a given value of the CORESET pool index that can be scheduled per component carrier during the same PMO.
[0168] In the example, It can be 2. Therefore, there can be up to 4 DCIs 615 scheduling the same component carrier 605 in the same PMO 610. In the example shown in the joint feedback scheme 600, DCIs 615-a to DCI 615-d (e.g., 4 DCIs 615) can be received during the PMO 610 and schedule PDSCHs 620-a to PDSCHs 620-d in the component carrier 605-a, respectively. DCIs 615-a and DCIs 615-b can be associated with CORESET pool index 0, and DCIs 615-c and DCIs 615-d can be associated with CORESET pool index 1, so the component carrier 605-a can have two values of the CORESET pool index.
[0169] In some cases, the DAIs may be sorted based on the total number of DCIs that schedule the same component carrier 605 in the same PMO 610. For example, the DAIs may first be sorted in increasing order of PDSCH start time for the same CORESET pool index, the same component carrier 605, and the same PMO 610; then the DAIs may be sorted in ascending order of CORESET pool index values for the same component carrier 605 and the same PMO 610; then the DAIs may be sorted in ascending order of component carrier index for the same PMO 610; then the DAIs may be sorted in ascending order of PMO index. Component carriers 605-a with two values of CORESET pool index may be counted. times for creating the HARQ ACK codebook in a given PMO.
[0170] For example, for CORESET pool index 0 in component carrier 605-a, PDSCH 620-a may occur earlier than PDSCH 620-b, so DCI 615-a may be associated with the first DAI 630-a and DCI 615-b may be associated with the second DAI 630-b. After the DAIs have been sorted for CORESET pool index 0 in component carrier 605-a of PMO 610, the DAIs may be sorted for CORESET pool index 1 in component carrier 605-a of PMO 610. In component carrier 605-a, PDSCH 620-c may occur before PDSCH 620-d, so DCI 615-c may be associated with the third DAI 630-c and DCI 615-d may be associated with the fourth DAI 630-d. After the DAIs in component carrier 605-a have been sorted, the DAIs in component carrier 605-b may be sorted. Both PDSCH 620-e and PDSCH 620-f may be associated with CORESET pool index 0, but PDSCH 620-e may appear before PDSCH 620-f in the time domain. Thus, DCI 615-e may be associated with the fifth DAI 630-e, and DCI 615-f may be associated with the sixth DAI 630-f. UE115 may generate a HARQ ACK codebook by setting bits in the codebook with HARQ ACK feedback for PDSCH 620 scheduled by the associated DCI 615, and send the HARQ ACK codebook on PUCCH 625.
[0171] Figure 7 An example of a joint feedback scheme 700 supporting feedback schemes for multi-component carrier scheduling and joint feedback reporting is shown in accordance with aspects of the present disclosure. In some examples, the joint feedback scheme 700 can implement aspects of the wireless communication system 100.
[0172] As reference Figure 6As described, the UE 115 may be configured for joint feedback reporting for multiple CORESET pools. The UE 115 may indicate support for multiple PDSCHs scheduled per cell per PMO. For example, the UE 115 may send a UE capability to the base station 105 indicating support for multiple PDSCHs scheduled for one component carrier during a single PMO. In some cases, the UE 115 may indicate to the base station 105 (e.g., by indicating UE capabilities) support for sorting DAIs for the PDSCH start time for the same component carrier and the same PMO. In some cases, the UE 115 may indicate the number of PDSCHs 720 that the UE 115 can be scheduled for per component carrier 705 per PMO 710. In other words, the number indicated by the UE capability signaling is interpreted as the total number of PDSCHs associated with the two values of the CORESET pool index (rather than per CORESET index value) that can be scheduled per component carrier during the same PMO.
[0173] In the example of the joint feedback scheme 700, the UE 115 may not be provided with a CORESET pool index for the active downlink bandwidth portion of the serving cell, or the UE 115 may be provided with a CORESET pool index having a value of 0 for one or more first CORESETs. Additionally, the UE 115 may be provided with a CORESET pool index having a value of 1 for one or more second CORESETs. The UE 115 may receive DCI 715-a to DCI 715-d on the component carrier 705 during the PMO 710. The DCI 715-a and DCI 715-c may be associated with a control resource pool index having a value of 0, and the DCI 715-b and DCI 715-d may be associated with a CORESET pool index having a value of 1.
[0174] In the same PMO 710, there may be a total number of DCIs 715 that schedule the same component carrier 705 (eg, component carriers 705 with two values of the CORESET pool index). Figure 6 A first example is described. In a second example, there may be at most as many DCIs as indicated by the UE. For example, the UE 115 may indicate support for "PDSCH-Number-perMOperCell", and for a component carrier 705 with two CORESET pool index values, there may be at most The two DCIs schedule the same component carrier 705. In this example, two PDSCHs 720 associated with different CORESET pool index values may have the same starting point.
[0175] In the example, It can be 4. Therefore, there may be up to 4 DCIs 715 scheduling the same component carrier 705 in the same PMO 710. In the example shown in the joint feedback scheme 700, DCIs 715-a to 715-d (e.g., 4 DCIs 715) can be received during the PMO 710 and schedule PDSCHs 720-a to 720-d in the component carrier 705, respectively. DCI 715-a and DCI 715-c can be associated with CORESET pool index 0, and DCI 715-b and DCI 715-d can be associated with CORESET pool index 1, so the component carrier 705 can have two values of the CORESET pool index.
[0176] In some cases, the DAIs may be sorted based on the total number of DCIs that schedule the same component carrier 705 in the same PMO 710. For example, the DAIs may first be sorted in ascending order of CORESET pool index values for the same PDSCH start time, the same component carrier 705, and the same PMO 710; then the DAIs may be sorted in ascending order of PDSCH start time for the same component carrier 705 and the same PMO 710; then the DAIs may be sorted in ascending order of component carrier index for the same PMO 710; then the DAIs may be sorted in ascending order of PMO index. Component carriers 705 with two values of CORESET pool index may be counted. times for creating the HARQ ACK codebook in a given PMO 710.
[0177] For example, PDSCH 720-a and PDSCH 720-b may have the same start time and be scheduled on the same component carrier 705 during the same PMO 710, but PDSCH 720-a may be associated with a smaller CORESET pool index value. Therefore, DCI 715-a may be associated with the first DAI 730-a, and DCI 715-b may be associated with the second DAI 730-b. PDSCH 720-c may have the next earliest PDSCH start time, so DCI 715-c may be associated with the third DAI 730-c and DCI 715-d may be associated with the fourth DAI 730-d. UE 115 may generate a HARQ ACK codebook by setting bits in the codebook with HARQ ACK feedback for PDSCH 720 scheduled by the associated DCI 715, and send the HARQ ACK codebook on PUCCH 725.
[0178] Figure 8 An example of a process flow 800 for supporting a feedback scheme for multi-component carrier scheduling and joint feedback reporting according to aspects of the present disclosure is shown. In some examples, the process flow 800 can implement aspects of the wireless communication system 100. The process flow 800 can be implemented by the UE 115-b, the base station 105-b, or both, which can be reference Figure 1 and Figure 2 Examples of UE 115 and base station 105 are described.
[0179] At 805, UE 115-b may receive a first DCI from the base station during PMO, the first DCI scheduling UE 115-b for a first PDSCH resource on a first component carrier and a second PDSCH resource on a second component carrier. At 810, UE 115-b may receive a second DCI from base station 105-b during PMO, the second DCI scheduling UE 115-b for a third PDSCH resource on a second component carrier. UE 115-b may monitor data from base station 105-b during the first, second, and third PDSCH resources.
[0180] At 815 , the UE 115 - b may identify a set of DAIs for a first DCI and a second DCI, wherein the first DCI has one or more DAIs whose values schedule PDSCH resources on different component carriers based on the first DCI.
[0181] In some cases, the UE 115-b may generate a HARQ ACK codebook whose order is based on the DAI set. At 820, the UE 115-b may send feedback (eg, including the codebook) based on the DAI set.
[0182] Fig. 9 An example of a process flow 900 for supporting a feedback scheme for multi-component carrier scheduling and joint feedback reporting according to aspects of the present disclosure is shown. In some examples, the process flow 900 can implement aspects of the wireless communication system 100. The process flow 900 can be implemented by a UE 115-c, a TRP 105-c, a TRP 105-d, or any combination thereof. The UE 115-c can be a reference Figure 1 and Figure 2 105 - d . Figure 1 and Figure 2The examples of base station 105 described, or TRP 105-c and TRP 105-d may be examples of TRPs for base station 105. For example, TRP 105-c and TRP 105-d may separate a transmitter and a receiver, which may transmit communications for base station 105.
[0183] At 905, UE 115-c may receive one or more first DCIs during PMO, the first DCI scheduling UE 115-c for corresponding one or more first PDSCH resources on a first component carrier, the one or more first DCIs being associated with a first CORESET pool index. At 910, UE 115-c may receive one or more second DCIs during PMO, the second DCI scheduling UE for corresponding one or more second PDSCH resources on a first component carrier, the one or more second DCIs being associated with a second CORESET pool index. In some cases, the first CORESET pool index may be associated with TRP 105-c and the second CORESET pool index may be associated with TRP 105-d.
[0184] At 915, the UE 115-c may identify a DAI set for the one or more first DCIs and the one or more second DCIs, wherein a value of the DAI set schedules PDSCH resources on the same component carrier based on both the one or more first DCIs and the one or more second DCIs.
[0185] UE 115-c may send feedback based on the DAI set. For example, UE 115-c may generate a HARQ ACK codebook including feedback for a PDSCH resource set. In some cases, at 920, UE 115-c may send feedback to TRP 105-c. Additionally or alternatively, UE 115-c may send feedback to TRP 105-d.

[0193] Fig.11 A block diagram 1100 of a device 1105 supporting a feedback scheme for multi-component carrier scheduling and joint feedback reporting according to aspects of the present disclosure is shown. The device 1105 may be an example of aspects of the device 1005 or UE 115 as described herein. The device 1105 may include: a receiver 1110, a communication manager 1115, and a transmitter 1145.
