Assignment index for dynamic feedback

Abstract

Methods, systems, and devices for wireless communication are described. A user equipment (UE) can order assignment indicator values for transmissions for use by feedback information in a feedback message. During a monitoring occasion, the UE can receive first control information on a first serving cell and second control information on a second serving cell, where each control information schedules a respective transmission for a scheduled serving cell. The UE can order the assignment indicator values for the transmissions based on an index associated with the first serving cell and the second serving cell (e.g., scheduling serving cells), an index associated with the scheduled serving cells, a start time of the transmissions, or some combination thereof, among other examples. The assignment indicator values can be associated with hybrid automatic repeat request acknowledgement (HARQ / ACK) feedback, such that the UE can use the assignment indicator values to construct and transmit the feedback message.

[0002] This patent application claims the benefit of U.S. Patent Application No. 17 / 148,251, filed January 13, 2021, entitled “Assignment Indices for Dynamic Feedback”, by Khoshnevisan et al., which has been assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field

[0003] The following text relates to wireless communication, including assignment indexes used for dynamic feedback. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. 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 (e.g., Long Term Evolution (LTE) systems, improved LTE (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems can employ technologies 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 simultaneously supporting communication with multiple communication devices (which may also be referred to as User Equipment (UE)). Summary of the Invention

[0005] The described technology relates to improved methods, systems, devices, and apparatuses for supporting assignment indexes for dynamic feedback. In summary, the described technology provides a method for determining the order of assignment indicator values ​​(e.g., downlink assignment indicator (DAI) values) in feedback messages when two scheduled cells schedule transmissions in the same serving cell at the same monitoring time. The assignment indicator value may be assigned (e.g., by the UE) to a transmission according to a set of rules and can be used as a temporary index to map each transmission to corresponding feedback information in a feedback message (e.g., a Hybrid Automatic Repeat Request (HARQ) feedback, such as ACK or NACK). The UE can use aspects of the described technology to determine the order of assignment indicator values ​​based on, for example, the index of the serving cell, the start time of the scheduled transmission, and other examples.

[0051] Figures 10 to 13 A flowchart illustrating a method for using an assignment index for dynamic feedback, which supports various aspects of this disclosure, is shown. Detailed Implementation

[0052] Wireless communication systems can use grants (e.g., downlink control information (DCI) grants, which may also be simply referred to as DCIs) to schedule communications. For example, a base station can send a DCI grant to a user equipment (UE) to schedule downlink transmissions, where each DCI grant identifies the resources and other information to be used for the corresponding downlink transmission. Typically, a DCI can indicate whether a feedback report is requested for a downlink transmission. For example, a DCI can indicate a request for a feedback report and can also identify parameters of the feedback report (or message). For example, a DCI can indicate whether the feedback message uses a Type II (e.g., dynamic) hybrid automatic repeat / request acknowledgment (HARQ-ACK) codebook design or a Type I HARQ-ACK codebook design. Furthermore, the assignment indicator field in the DCI (e.g., a downlink assignment indicator (DAI) field) can indicate the digital sequence (e.g., a counting sequence for downlink transmissions associated with the same HARQ reporting timing) to be reported in the feedback message. In other words, the assignment indicator can be assigned to downlink transmissions and can be used as a temporary index to map downlink transmissions to their corresponding HARQ feedback.

[0053] Therefore, the UE can group HARQ feedbacks (e.g., ACK and NACK) for multiple downlink transmissions into common feedback messages (e.g., Physical Uplink Control Channel (PUCCH)) based on the assignment indicator value for each transmission. The UE can determine the order of the assignment indicator values ​​for downlink transmissions in the feedback messages based on one or more rules (e.g., based on one or more associated indices). For example, the assignment indicator values ​​can be ordered based on a scheduled serving cell index (e.g., an index of the serving cell for which the transmission is scheduled) or a monitoring timing index (e.g., an index of the monitoring timing in which the DCI is received). However, in some cases, such rules may be unsuitable or have limited applicability, and the UE may therefore be unable to determine the order of the assignment indicator values ​​in such situations. For example, if two DCIs in two different scheduled serving cells schedule two transmissions in the same scheduled serving cell during the same monitoring timing, the UE may face challenges in ordering the assignment indicator values ​​for the two scheduled transmissions.

[0054] The various techniques described herein support determining the order of assignment indicator values ​​(e.g., DAIs) used for downlink transmissions when two scheduling serving cells schedule transmissions in the same scheduled serving cell during the same monitoring time. For example, a UE may receive a first DCI on a first scheduling serving cell and a second DCI on a second scheduling serving cell during the same monitoring time, where the DCI schedules transmissions for the scheduled serving cell. The UE may determine the order of the DAIs used for transmissions in a feedback message and may construct a HARQ-ACK codebook (e.g., a Type 2 or dynamic HARQ-ACK codebook) corresponding to the transmission based on the DAIs.

[0055] In the first example, the UE can determine the order of DAI values ​​for each transmission based on the index of the serving cell. The UE can sort the DAIs in ascending order of the serving cell index. In some cases, the DCI can be scheduled for transmissions in two or more scheduled serving cells, and the DAIs can be sorted first in ascending order of the serving cell index, and then in ascending order of the scheduled serving cell index. In some examples, the UE can receive such a DCI at multiple different monitoring times, and the UE can sort the DAIs first in ascending order of the serving cell index, then in ascending order of the scheduled serving cell index, and finally in ascending order of the monitoring time.

[0056] In the second example, the UE can determine the order of DAI values ​​for each scheduled transmission based on the start time of the scheduled transmission. The UE can first sort the DAIs in ascending order of their start times. If transmissions have the same start time or are scheduled for multiple serving cells, the UE can first sort the DAIs in ascending order of their start times, and then sort them in ascending order of their serving cell indices. Furthermore, if the UE receives DCIs at multiple different monitoring times, the UE can finally sort the DAIs in ascending order of their monitoring times.

[0057] The various aspects of this disclosure are first described in the context of a wireless communication system. Then, these aspects are described with reference to transmission diagrams and process flows. The various aspects of this disclosure are further illustrated by apparatus diagrams, system diagrams, and flowcharts relating to assignment indices for dynamic feedback, and are described with reference to these diagrams.

[0058] Figure 1Examples of a wireless communication system 100 supporting assignment indexes for dynamic feedback according to various aspects of this disclosure are shown. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an improved LTE (LTE-A) network, an LTE-APro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices, or any combination thereof.

[0059] Base stations 105 can be distributed throughout a geographical area to form a wireless communication system 100, and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 on the coverage area 110. Coverage area 110 can be an example of a geographical area where base station 105 and UE 115 can support signal transmission according to one or more radio access technologies.

[0060] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be devices of different forms or with different capabilities. Figure 1 Some example UE 115s are shown in the document. The UE 115 described herein is capable of communicating with various types of devices, such as other UE 115s, base station 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 As shown.

[0061] Base station 105 can communicate with core network 130, communicate with each other, or perform both of these operations. For example, base station 105 can interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) on backhaul links 120 (e.g., via X2, Xn, or other interfaces), or indirectly (e.g., via core network 130), or perform both of these operations. In some examples, backhaul link 120 can be or includes one or more radio links.

[0062] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, node B, evolved node B (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home evolved node B, or some other suitable term.

[0063] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, and other examples. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, and other examples, which may be implemented in various items such as appliances, vehicles, meters, and other examples.

[0064] The UE 115 described in this document can communicate with various types of devices, such as other UE 115s that can sometimes act as repeaters, as well as base station 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, and other examples, such as... Figure 1 As shown.

[0065] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources having 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., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0066] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as Orthogonal Frequency Division Multiplexing (OFDM) or Discrete Fourier Transform Spread Spectrum OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can 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 UE 115 receives and the higher the order of the modulation scheme, the higher the data rate can be for UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity used for communication with UE 115.

[0067] It can be expressed in a basic unit of time (which can be, for example, T). s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N f The time interval for base station 105 or UE 115 can be represented as a multiple of the maximum supported Discrete Fourier Transform (DFT) size. The time interval for communication resources can be organized based on radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0068] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., this depends on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N) f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0069] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst form of a shortened TTI (sTTI)).

[0070] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by the number of symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a group of UEs 115. For example, one or more of the UEs 115 can monitor or search for control regions against control information based on one or more search space sets, and each search space set can include one or more control channel candidates arranged in a cascaded manner at one or more aggregation levels. The aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The 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 used to send control information to a specific UE 115.

[0071] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used (e.g., on a carrier) to communicate with base station 105 and may be associated with an identifier used to distinguish neighboring cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or other identifier). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors (such as the capabilities of base station 105), the range of such cells can range from small areas (e.g., structures, subsets of structures) to large areas. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, and other examples.

[0072] Macro cells typically cover a relatively large geographical area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 115 with a service subscription to a network provider supporting the macro cell. In contrast, small cells can be associated with a lower-power base station 105 and can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UE 115 with a service subscription to a network provider, or restricted access to UE 115 associated with the small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a residence or office). Base station 105 can support one or more cells and can also support communication on one or more cells using one or more component carriers.

[0073] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0074] In some examples, base station 105 may be mobile, and therefore provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but 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. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0075] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, 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 mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private 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 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 are used interchangeably herein.

[0076] In some examples, UE 115 is able to communicate directly with other UE 115 on a device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, groups of UE 115s communicating via D2D communication can utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.

[0077] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function unit (AMF)) managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function unit (UPF)) routing packets to or interconnecting with external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to IP service 150 for one or more network operators. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0078] Some network devices (e.g., base station 105) may include sub-components 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 a radio headend, smart radio headend, or transmit / receive point (TRP)). 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 individual network devices (e.g., radio headends and ANCs) or incorporated into a single network device (e.g., base station 105).

[0079] Wireless communication system 100 can operate using one or more frequency bands (typically in the range of 300 MHz to 300 GHz). The region from 300 MHz to 3 GHz is often referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves can be sufficiently permeable to penetrate structures for use in macrocells to provide service to UE 115 located indoors. Compared to the transmission of smaller frequencies and longer waves in the lower 300 MHz portion of the spectrum in the High Frequency (HF) or Very High Frequency (VHF) regions, UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0080] Wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio frequency spectrum bands, devices (such as base station 105 and UE 115) can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands can be based on carrier aggregation configurations that combine component carriers operating in licensed frequency bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and other examples.

[0081] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operation or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array having a number of rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.

[0082] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to form or guide an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating relative to a specific orientation of the antenna array experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with the transmitting or receiving device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).

[0083] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. HARQ feedback is a technique used to increase the likelihood of correct data reception 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 throughput at the Media Access Control (MAC) layer under poor radio conditions (e.g., low signal and noise conditions). In some examples, the device can support same-slot HARQ feedback, where the device can provide HARQ feedback for data received in a previous symbol within a specific time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0084] In some examples, UE 115 can group HARQ feedbacks for multiple downlink transmissions into a common feedback message, such as a PUCCH transmission. In such examples, UE 115 can determine the order of assignment indicator values ​​(e.g., DAI values) for each downlink transmission and can construct a codebook (e.g., a type 2 HARQ / ACK codebook) based on the order of the assignment indicator values. UE 115 can determine the order of assignment indicator values ​​for downlink transmissions according to one or more rules. The assignment indicator values ​​can be used as temporary indexes to map each downlink transmission to its corresponding HARQ feedback in the PUCCH message.

[0085] UE 115 may receive (e.g., from base station 105) DCI during monitoring events (such as PDCCH monitoring events (PMO)). The DCI may be received on a first serving cell (which may be referred to as the scheduling serving cell) and may be scheduled for one or more transmissions (e.g., Physical Downlink Shared Channel (PDSCH) transmissions, Semi-Persistent Scheduling (SPS) resource releases) in a second serving cell (e.g., component carrier, primary cell, secondary cell, etc.) (which may be referred to as the scheduled serving cell). UE 115 may receive additional DCIs on other scheduling serving cells to schedule additional transmissions for the scheduled serving cell. In some examples, additional DCIs may be received by UE 115 during the same monitoring event.

[0086] UE 115 can determine the order of DAI values ​​for each scheduled transmission for one or more scheduled serving cells based on one or more rules. In a first example, UE 115 can identify an index associated with each scheduled serving cell and can determine the order of DAI values ​​for each scheduled transmission based on the index of the scheduled serving cell. For example, UE 115 can determine the order of DAI values ​​for transmissions scheduled by DCI received at the same monitoring time in ascending order of the scheduled serving cell index. In this example, a transmission scheduled by DCI received on a scheduled serving cell with index 1 can be assigned a lower value compared to a transmission scheduled by DCI received on a scheduled serving cell with index 2. In a second example, UE 115 can identify the start time for each scheduled transmission and can determine the order of DAI values ​​based on the start time. For example, UE 115 can determine the order of DAI values ​​in ascending order of the transmission start time for transmissions scheduled by DCI received at the same monitoring time. In some cases, UE 115 may use some combination of the techniques described herein, or may use other techniques besides those described herein, or other techniques combined with those described herein.

[0087] Figure 2 Examples of transmission configuration 200 supporting assignment indexes for dynamic feedback according to various aspects of this disclosure are shown. In some examples, transmission configuration 200 may implement various aspects of wireless communication system 100. Transmission configuration 200 illustrates serving cell 205, as shown in reference... Figure 1 The described base station 105 and UE 115 can communicate on serving cell 205. For example, the base station can send DCI 210 to the UE during monitoring time 215. DCI 210 can schedule one or more transmissions, such as PDSCH 220. As described herein, the UE can determine the order of assignment indicator values ​​(e.g., DAI values) for each PDSCH 220, where the assignment indicator values ​​can be used to map PDSCH 220 to corresponding feedback (e.g., HARQ) information. The UE can send feedback information for PDSCH 220 in common PUCCH 225.

[0088] During monitoring time 215, the UE may monitor and receive control information (e.g., DCI 210) on one or more serving cells 205, wherein the control information includes scheduling information 205 for one or more transmissions (e.g., PDSCH 220) for one or more serving cells. The serving cell 205 on which DCI 210 is received may be referred to as the scheduling serving cell, and the serving cell 204 on which PDSCH 220 is scheduled may be referred to as the scheduled serving cell. Therefore, the scheduling serving cell (e.g., serving cell 205-b) may schedule PDSCH 220 for one or more scheduled serving cells (e.g., serving cells 204-a and 205-c). In some cases, the scheduling serving cell may schedule PDSCH 220 for itself; for example, the scheduling serving cell and the scheduled serving cell may be the same. Each serving cell 205 may be associated with a serving cell index. In some cases, the serving cell may be referred to as a component carrier, and the serving cell index may be an example of a component carrier index.

[0089] The UE can receive PDSCH 220 on serving cell 205 based on scheduling information and can determine feedback for each PDSCH 220. In some examples, DCI 210 can instruct the base station to request feedback for the corresponding PDSCH 220, and in some cases, instruct the base station to request parameters for the feedback message. As an example, DCI 210 can instruct the UE to construct a type 2 (e.g., dynamic) HARQ / ACK codebook for the feedback message. This feedback can indicate ACK or NACK to the base station for each PDSCH 220. For example, if the UE does not receive PDSCH 220 or does not receive PDSCH 220 correctly, the UE can indicate NACK for PDSCH 220 in the corresponding feedback. Alternatively, if the UE successfully receives PDSCH 220, the UE can indicate ACK in the corresponding feedback.

[0090] The UE can group feedback from multiple PDSCH 220s into a common feedback message, which can be transmitted via PUCCH 225. To support grouped feedback, the UE can determine the order of the assignment indicator values ​​(e.g., DAI) used for each PDSCH 220, and can use the DAI order to map the PDSCH 220s to their corresponding feedbacks in PUCCH 225. That is, the UE can use the DAI order to construct the HARQ / ACK codebook transmitted via PUCCH 225. For example, the UE can construct the HARQ-Ack codebook based on the DAI values ​​assigned to PDSCH 220 according to one or more rules regarding the ordering of DAI values. For example, the UE can determine the order of DAI values ​​based on one or more conditions. For example, the first rule could be to assign DAI values ​​after each monitoring time. For example, a DCI received during a first monitoring time might receive a lower DAI value compared to a DCI received during a second monitoring time that occurs after the first monitoring time. In some examples, the DAI value may be based on the monitoring timing 215 in which the DCI 210 scheduled for PDSCH 220 is received. If the UE receives the first DCI 210 scheduled for the first PDSCH 220 during the first monitoring timing 215, and also receives the second DCI 210 scheduled for the second PDSCH 220 during the second monitoring timing 215, the UE may determine the order of the DAI values ​​for the first and second PDSCH 220 based on the order in which the corresponding DCI 210s are received in the different monitoring timings. The order determined by the UE may be based, for example, on the lower DAI value for the PDSCH 220 scheduled by the DCI 210 received in the earlier monitoring timing 215; in this particular example, the order determined by the UE may be based on a DAI value for the first PDSCH 220 that is lower than the DAI value assigned to the second PDSCH 220.

[0091] As an example of the second rule, the UE can determine the order of DAI values ​​based on the index associated with the scheduled serving cell of PDSCH 220, where the scheduled serving cell is the serving cell 205 to which PDSCH 220 is scheduled. Using the same example as above, a first PDSCH 220 can be scheduled for serving cell 205 associated with index 2, and a second PDSCH 220 can be scheduled for serving cell 205 associated with index 1. The DAI values ​​can be ordered correspondingly to the indexes, for example, such that a lower index of the scheduled serving cell corresponds to a lower DAI value. Therefore, a value 2 (e.g., the second DAI) can be assigned to the first PDSCH 220, while a value 1 (e.g., the first DAI in the order) can be assigned to the second PDSCH 220.

[0092] However, in some cases, the first or second rule alone may not be sufficient for the UE to determine the order of DAI values ​​used for PDSCH 220, and the UE may combine multiple rules. For example, if two different scheduling serving cells (e.g., cells 205-b and 205-c) schedule different transmissions (e.g., using PDSCHs of DCIs 210-a and 210-b) in the same scheduled cell (e.g., cell 205-b), the UE may not be able to order the assignment indicator values ​​between the two scheduled transmissions. In some examples, the UE may receive two DCIs 210 during a first monitoring opportunity 215 and on a first scheduling serving cell, which are scheduled for two PDSCHs 220 used for the first scheduled serving cell. The UE may also receive a second pair of DCIs 210 during the same monitoring opportunity 215 on a second scheduling serving cell, which are scheduled for a second pair of PDSCHs 220 used for the second scheduled serving cell. During the second monitoring time 215, the UE may receive a third two DCIs 210, which are scheduled for a third two PDSCHs 220 of a third scheduled serving cell. The first scheduled serving cell may be associated with index 2, the second scheduled serving cell may be associated with index 3, and the third scheduled serving cell may be associated with index 1. The UE may apply a first rule to determine the DAI value based on the first and second monitoring times 215. For example, the PDSCH 220 scheduled by the DCI 210 received in the first monitoring time 215 may have a lower DAI value compared to the PDSCH 220 scheduled by the DCI 210 received in the second monitoring time 215. A second rule may be applied to further determine the DAI value based on the index of the scheduled serving cell of the PDSCH 220 scheduled by the DCI 210 received during the same monitoring time 215. For example, the first two PDSCH 220s are associated with index 2, and the second two PDSCH 220s are associated with index 3; therefore, the first two PDSCH 220s can be sorted to have lower values ​​compared to the second two PDSCH 220s.

[0093] To further refine the DAI values ​​used for PDSCH 220s scheduled by DCI 210s received during the same monitoring period 215 and associated with the same scheduled serving cell (and therefore the same scheduled serving cell index), the UE can use additional rules to determine the start time for each PDSCH 220 and can determine the order of the DAI values ​​based on the start time. For example, the UE can identify which of the first two PDSCH 220s has an earlier start time and can determine that the order including the earlier start time is earlier in that order. In this way, the UE can cumulatively sort the DAI values ​​in the feedback messages according to various rules.

[0094] However, the UE may encounter additional scenarios where existing rules may not apply, and the UE may be unable to determine the order of DAI values. For example, the rules described above may not cover the case where PDSCH 220 is scheduled by DCI 210 received on different scheduling serving cells. For instance, the UE may receive two DCI 210s on two different scheduling serving cells at the same monitoring time 215, where each of the two DCI 210s schedules PDSCH 220 in the same scheduled serving cell. That is, the two PDSCH 220s may be associated with the same scheduled serving cell index and the same monitoring time 215, making the first and second rules potentially useless in determining the order of DAI values. Additionally, some existing rules (such as start time rules) may be restricted to ordering DAI values ​​with the same scheduling serving cell.

[0095] According to the techniques described herein, the UE can support additional rules for ordering DAI values ​​in feedback messages, and specifically, additional rules for PDSCH 220 scheduled by DCI 210 received on different scheduling serving cells. For example, during a first monitoring period, the UE can receive first and second control information on first and second serving cells, respectively, where the first and second control information each schedules a corresponding transmission for a third serving cell. In this example, the first and second serving cells can be considered scheduling serving cells, and the third serving cell can be considered a scheduled serving cell. In some cases, the scheduling serving cell can schedule itself (e.g., the first and third serving cells can be the same serving cell). In any case, the UE can identify an index associated with each serving cell and can determine the order of DAI values ​​based on that index and one or more rules. For example, a rule could be that a lower DAI value corresponds to a lower scheduling serving cell index. The UE can identify an index associated with a serving cell considered a scheduling serving cell and can determine the order of DAI values ​​for the first and second transmissions based on that index. Alternatively, a rule could be that a lower DAI value corresponds to a lower scheduled serving cell index. The UE can identify the index associated with the serving cell that is considered to be the scheduled serving cell, and can determine the order of the DAI values ​​used for the first and second transmissions.

[0096] like Figure 2 As shown, during the first monitoring opportunity 215, the UE can receive DCIs 210-a and 210-c on serving cell 205-b, and receive DCI 210-b on serving cell 205-c. DCIs 210-a, 210-b, and 210-c can schedule the first, second, third, and fourth PDSCHs 220 on serving cell 205. As shown, DCI 210-c can schedule the first PDSCH 220 for serving cell 205-a and the fourth PDSCH 220 for serving cell 205-c, DCI 210-a can schedule the second PDSCH 220 for serving cell 205-b, and DCI 210-b can schedule the third PDSCH 220 for serving cell 205-b.

[0097] During the second monitoring period 215, the UE may receive DCI 210-d on serving cell 205-b and DCIs 210-e to 210-g on serving cell 205-c. DCIs 210-d to 210-f may be scheduled for the fifth, sixth, and seventh PDSCHs 220 of serving cell 205-b, respectively. DCI 210-g may be scheduled for the eighth PDSCH 220 of serving cell 205-c.

[0098] The UE can receive PDSCH 220 on the scheduled serving cell 205 according to the corresponding DCI 210, and can determine the feedback for each PDSCH 220. The UE can determine the order of DAI values ​​to be used in the feedback message according to one or more rules. For example, the UE can sort the DAI values ​​in ascending order of monitoring time 215, index of the scheduled serving cell 205, index of the scheduling serving cell 205, start time of PDSCH 220, or some combination thereof. Figure 2 In the example, the UE can prioritize the DAI value received in DCI 210 during the first monitoring time 215 (e.g., since the first monitoring time occurs before the second monitoring time 215, the DAI received during the first monitoring time 215 can be prioritized).

[0099] For PDSCH 220 scheduled by DCI 210 (such as the first to fourth DCI 210) received in the same monitoring time 215, the UE can determine the order of DAI values ​​based on the order of the indexes of the scheduled serving cell. The UE can identify the index associated with the serving cell 205 that scheduled the PDSCH 220 for each PDSCH 220. Serving cell 205-a can correspond to index 0, serving cell 205-b can correspond to index 1, and serving cell 205-c can correspond to index 2. Therefore, the first PDSCH 220 can be associated with the scheduled serving cell index 0, the second and third PDSCH 220 can be associated with the scheduled serving cell index 1, and the fourth PDSCH 220 can be associated with the scheduled serving cell index 2. Therefore, the UE can determine the order of DAI values ​​in ascending order based on the scheduled serving cell index, such that the first PDSCH 220 is sorted as lower (e.g., the lowest value), and the second and third PDSCH 220s are sorted as lower than the fourth PDSCH 220.

[0100] For a PDSCH 220 scheduled by a DCI 210 received at the same monitoring time 215 and associated with the same scheduled serving cell index (such as the second and third PDSCH 220), the UE can determine the order of the DAI values ​​based on the index of the scheduling serving cell. Alternatively, the DAI values ​​can be ordered based on the serving cell 205 used to transmit the scheduled PDSCH 220. For example, serving cell 205-b is used to transmit DCI 210-a for the second PDSCH 220, and serving cell 205-c is used to transmit DCI 210-b for the third PDSCH 220. The UE can identify that serving cell 205-b (e.g., the scheduling serving cell for the second PDSCH 220) is associated with index 1, and serving cell 205-c (e.g., the scheduling serving cell for the third PDSCH 220) is associated with index 2. As a non-limiting example, the UE may determine that the DAI value used for PDSCH 220 associated with a lower serving cell index value is ranked lower than the DAI associated with a higher serving cell index value. Therefore, the UE may rank the DAI value used for the second PDSCH 220 lower than the DAI value assigned to the third PDSCH 220.

[0101] The UE can determine the order of DAI values ​​for the fifth through eighth PDSCHs 220 in a similar manner, since the fifth through eighth PDSCHs 220 are scheduled by DCIs 210 received in the same second monitoring time 215. That is, the UE can determine the order of DAI values ​​according to the ascending order of the associated scheduled serving cell index and the associated scheduling serving cell index. The order of DAI values ​​for the fifth through seventh PDSCHs 220 can be determined based on the corresponding associated scheduling serving cell index. For example, the fifth PDSCH 220 is scheduled by DCI 210-d received on serving cell 205-b, while the sixth and seventh PDSCHs 220 are scheduled by DCIs 210-e and 210-f received on serving cell 205-c. Therefore, the fifth PDSCH 220 is associated with scheduling serving cell indices lower than those of the sixth and seventh PDSCHs 220, and can be ordered accordingly by lower DAI values.

[0102] Because the sixth and seventh PDSCH 220s are associated with the same scheduling serving cell index, the same scheduled serving cell index, and the same monitoring timing 215, the UE can determine the order of the DAI values ​​for the sixth and seventh PDSCH 220 based on the start time of each PDSCH 220. For example, the UE can determine that the DAI value for the PDSCH 220 has a lower value because it has an earlier start time. Therefore, since the sixth PDSCH 220 starts earlier than the seventh PDSCH 220, the DAI value for the sixth PDSCH 220 can be ranked lower than the DAI value for the seventh PDSCH 220.

[0103] The UE can send feedback information for PDSCH 220 in a feedback message via PUCCH 225, where the feedback information may include ACK or NACK for each PDSCH 220. The UE can construct a codebook based on sorting the DAI values, where feedback is sent in order corresponding to the DAI values. For example, the UE can sort the feedback in ascending order from the lowest DAI value to the highest DAI value, where feedback for the first PDSCH 220 is sent first, followed by feedback for the second PDSCH 220, and so on, until feedback for each PDSCH 220 has been sent.

[0104] Figure 3 Examples of transmission configuration 300 supporting assignment indexes for dynamic feedback according to various aspects of this disclosure are shown. In some examples, transmission configuration 300 may implement various aspects of wireless communication system 100. Transmission configuration 300 shows serving cell 305, as referenced Figure 1 The described base station 105 and UE 115 can communicate on serving cell 305. For example, the base station can send DCI 310 to the UE during monitoring time 315. DCI 310 can schedule one or more transmissions, such as PDSCH 320. As described herein, the UE can determine the order between assignment indicator values ​​(e.g., DAI values) for each PDSCH 320, where the assignment indicator values ​​can be used to map PDSCH 320 to corresponding feedback (e.g., HARQ) information in a feedback message. The UE can send feedback information for PDSCH 320 in a common PUCCH 325.

[0105] For reference Figure 2 As described, the UE can determine the order of the assignment indicator values ​​(e.g., DAI) for each PDSCH 320 according to one or more rules. For example, the UE can determine the order of the DAI values ​​based on one or more conditions. Figure 3 In the example, the UE can be based on, except for the reference Figure 2 Outside of the rules described or as a reference Figure 2 The order of DAI values ​​is determined by an alternative set of rules to the described rules. For example, the UE can determine the order of DAI values ​​based on the monitoring timing 315 in which the DCI 310, in which the scheduling PDSCH 320 is received, or based on the index associated with the scheduled serving cell and / or the scheduling serving cell in the PDSCH 320. However, if the PDSCH 320 is received in the same monitoring timing 315 and associated with the same scheduled serving cell index, the UE can determine the order of DAI values ​​based on the start time of the PDSCH 320.

[0106] like Figure 3 As shown, during the first monitoring opportunity 315, the UE can receive DCIs 310-a and 310-c on serving cell 305-c, and receive DCI 310-b on serving cell 305-b. Each of DCIs 310-a, 310-b, and 310-c can schedule PDSCH 320 on serving cell 305. DCIs 310-a, 310-b, and 310-c can include DAI for the scheduled PDSCH 320. As shown, DCI 310-a can schedule a first PDSCH 320 for serving cell 305-b, DCI 310-b can schedule a second PDSCH 320 for serving cell 305-b, and DCI 310-c can schedule a third PDSCH 320 for serving cell 305-c and a fourth PDSCH 320 for serving cell 305-a. During the second monitoring period 315, the UE can receive DCI 310-e on serving cell 305-b, and DCI 310-d, 310-f, and 310-g on serving cell 305-c. DCI 310-d to 310-f can be scheduled for the fifth, sixth, and seventh PDSCH 320s of serving cell 305-b, respectively. DCI 310-g can be scheduled for the eighth PDSCH 320 of serving cell 305-c.

[0107] The UE can receive PDSCH 320 on the scheduled serving cell 305 according to the corresponding DCI 310, and can determine the feedback for each PDSCH 320. The UE can determine the order of the DAI values ​​for each PDSCH 320 to be used in the feedback message based on the monitoring timing 315. For example, the UE can determine that the DAI value for PDSCH 320 scheduled by the DCI 310 received in the first monitoring timing 315 is lower than the DAI value for PDSCH 320 scheduled by the DCI 310 received in the second monitoring timing 315 in that order, because the first monitoring timing 315 occurs before the second monitoring timing 315.

[0108] For PDSCH 320s scheduled by DCI 310s received in the same monitoring time 315 (such as the first to fourth DCI 310), the UE can determine the order of DAI values ​​based on the order of the indexes of the scheduled serving cells. The UE can identify the index associated with the serving cell 305 that scheduled the PDSCH 320 for each PDSCH 320. Serving cell 305-a can correspond to index 0, serving cell 305-b can correspond to index 1, and serving cell 305-c can correspond to index 3. The fourth PDSCH 320 can therefore be associated with the scheduled serving cell index 0, the first and second PDSCH 320s can be associated with the scheduled serving cell index 1, and the third PDSCH 320 can be associated with the scheduled serving cell index 2. Therefore, the UE can determine the order of DAI values ​​in ascending order based on the index of the scheduled serving cell, such that the fourth PDSCH 320 is sorted with the lowest DAI value, and the first and second PDSCH 320s are sorted with DAI values ​​lower than those used for the third PDSCH 320.

[0109] For PDSCH 320s (such as first and second PDSCH 320s) scheduled by DCI 310s received at the same monitoring time 315 and associated with the same scheduled serving cell index, the UE can determine the order of DAI values ​​based on the start time of the PDSCH. The UE can identify the start time of each of the first and second PDSCH 320s and can determine the order of DAI values ​​accordingly. For example, a lower DAI value may correspond to an earlier start time.

[0110] The UE can determine the order of DAI values ​​for the fifth through eighth PDSCH 320s in a similar manner, since the fifth through eighth PDSCH 320s are scheduled by DC I 310 received in the same second monitoring time 315. That is, the UE can determine the order of DAI values ​​according to the ascending order of the associated scheduled serving cell index and the start time of the PDSCH 320s. The fifth through seventh PDSCH 320s are scheduled for serving cell 305-b associated with index 1, and therefore can be assigned a lower DAI value compared to the eighth PDSCH 320, which is scheduled for serving cell 305-c associated with index 3. The fifth through seventh PDSCH 320s can be assigned DAI values ​​based on their respective start times. For example, the fifth PDSCH 320 starts earlier than the sixth PDSCH 320, and the sixth PDSCH 320 subsequently starts earlier than the seventh PDSCH 320. The UE can determine that the DAI value of PDSCH 320 with an earlier start time is lower in the sequence. Therefore, the fifth to seventh PDSCH 320s can be ordered in ascending order, for example, the fifth PDSCH 320 has a lower value than the sixth PDSCH 320 in this sequence, and the sixth PDSCH 320 in turn has a lower value than the seventh PDSCH 320 in this sequence.

[0111] The UE can send feedback information for PDSCH 320 in a feedback message via PUCCH 325, whereby the feedback information may include ACK or NACK for each PDSCH 320. The UE can construct a codebook based on sorting the DAI values, where feedback is sent in order corresponding to the DAI values. For example, the UE can sort the feedback in ascending order from the lowest DAI value to the highest DAI value, where feedback for the first PDSCH 320 is sent first, followed by feedback for the second PDSCH 320, and so on, until feedback for each PDSCH 320 has been sent.

[0112] Figure 4Examples of a process flow 400 supporting an assignment index for dynamic feedback according to various aspects of this disclosure are shown. In some examples, process flow 400 may implement various aspects of wireless communication system 100. For example, process flow 400 may include base station 105-a and UE 115-a, which may be examples of corresponding wireless devices as described herein. In the following description of process flow 400, operations between UE 115-a and base station 105-a may be transmitted in a different order than shown, or operations performed by UE 115-a and base station 105-a may be performed in a different order or at different times. Certain operations may be excluded from process flow 400, or other operations may be added to process flow 400. Although UE 115-a and base station 105-a are shown performing operations of process flow 400, any wireless device may perform the operations shown. Furthermore, although Figure 4 An example of communication between UE 115-a and base station 105-a is shown, but the techniques described herein can be applied to communication between any number of wireless devices.

[0113] Base station 105-a and UE 115-a can communicate using one or more cells and / or component carriers (such as serving cell, primary cell, secondary cell, or some combination thereof, and other examples). During monitoring periods, base station 105-a can send control information to UE 115-a to schedule transmissions for UE 115-a. The control information can be sent on a first serving cell (which may be referred to as the scheduling serving cell) and can be scheduled for transmissions for the first serving cell or for one or more other serving cells (which may be referred to as the scheduled serving cells).

[0114] At point 405, base station 105-a can transmit first control information (e.g., first DCI) on a first serving cell (e.g., first scheduling serving cell) and second control information (e.g., second DCI) on a second serving cell (e.g., second scheduling serving cell) during a first monitoring opportunity (e.g., PMO). The first DCI and the second DCI can be respectively scheduled for a first transmission and a second transmission (e.g., PDSCH, SPS release) for a third serving cell (e.g., first scheduled serving cell). In some aspects, the third serving cell can be the first serving cell; that is, both the first serving cell and the second serving cell can schedule transmissions for the first serving cell. In some examples, the first serving cell can be a primary cell, and the second serving cell can be a secondary cell.

[0115] In some examples, base station 105-a may transmit third control information (e.g., third DCI) on the first serving cell during the same monitoring period. In some cases, the third DCI is scheduled for a third transmission on the third serving cell, while in others, the third DCI is scheduled for a third transmission on the fourth serving cell (e.g., the second scheduled serving cell).

[0116] In some examples, at 410, base station 105-a may transmit a third DCI during a second monitoring period different from the first monitoring period. The second monitoring period may occur after the first monitoring period.

[0117] At 415, base station 105-a can transmit and UE 115-a can receive transmissions scheduled by DCI on the corresponding serving cell.

[0118] At 420, UE 115-a can identify the index associated with each serving cell. UE 115-a can identify a first index associated with a first serving cell and a second index associated with a second cell. In some cases, UE 115-a can optionally identify a third index of a third serving cell (e.g., scheduled by the first, second, and / or third DCI). Additionally, UE 115-a can optionally identify a fourth index of a fourth serving cell (e.g., scheduled by the third DCI).

[0119] At 425, in some examples, UE 115-a can identify the start time for the scheduled transmission. For example, if UE 115-a receives a third DCI scheduled for a third transmission in a third serving cell at 405 (e.g., during the first monitoring period and on the first serving cell), UE 115-a can identify a first start time for the first transmission and a second start time for the third transmission.

[0120] At 430, UE 115-a can determine the order of assignment indicator values ​​(e.g., DAI values) associated with HARQ / ACK feedback for scheduled transmissions based on the index identified at 420, the start time identified at 425, the corresponding monitoring timing, or some combination thereof. UE 115-a can determine the order between the first DAI value for the first transmission and the second DAI value for the second transmission based on the first index of the first serving cell and the second index of the second serving cell. That is, for DCIs received at the same monitoring timing, the DAI values ​​can be ordered based on the index of the serving cell used to transmit the scheduled transmission. In other words, the DAI values ​​for each transmission can be sorted in the feedback message based on the corresponding scheduling serving cell index. For example, UE 115-a can determine the order between the first and second DAI values ​​in ascending order of the serving cell index, such that a lower value of the first DAI value corresponds to a lower serving cell index value.

[0121] When UE 115-a receives a third DCI scheduling a third transmission, UE 115-a can determine the order of the DAI value for the third transmission at 430 among other DAI values. In some examples, receiving a third DCI scheduling a third transmission can also change the order of DAI values. For example, a third transmission can be scheduled for a third serving cell via a third DCI, and the third DCI can be received at the first monitoring time (i.e., the same monitoring time as the first and second DCIs) and on the first serving cell. Therefore, the third transmission can be associated with the same scheduling serving cell index as the first transmission. In such an example, in addition to the serving cell index, UE 115-a can also use the start time identified at 425 to sort the DAI values. As an illustrative example, UE 115-a can determine the order between the DAI values ​​for the first and third transmissions based on the start time of the first transmission and the start time of the third transmission, where a lower DAI value corresponds to an earlier start time.

[0122] If UE 115-a receives the third DCI during the second monitoring opportunity, UE 115-a may determine the order of the DAI value for the third transmission relative to other DAI values ​​based on the second monitoring opportunity that occurs after the monitoring opportunity, for example, where the higher DAI value corresponds to the second monitoring opportunity that occurs after the first monitoring opportunity (and the lower DAI value of the first and / or second transmission corresponds to the first monitoring opportunity that occurs before the second monitoring opportunity).

[0123] Alternatively, if the third DCI is scheduled for a third transmission in the fourth serving cell, UE 115-a can determine the order of the DAI values ​​used for the third transmission relative to other DAI values ​​based on the indices of the third serving cell (e.g., scheduled by the first and second control information) and the fourth serving cell. That is, UE 115-a can determine the order of the DAI values ​​used for the transmission based on the index of the scheduled serving cell. The third and fourth serving cells can be associated with corresponding serving cell indices, and UE 115-a can use these indices to determine the order of the DAI values ​​used for the third transmission relative to other DAI values, where a lower DAI value may correspond to a lower serving cell index.

[0124] At position 435, UE 115-a can send feedback information to base station 105-a for at least the first and second transmissions based on the DAI values ​​ordered at position 430. The feedback information may include HARQ / ACK or HARQ / NACK for each transmission. In some examples, the feedback information can be sent on the PUCCH.

[0125] Figure 5 Examples of a process flow 500 supporting an assignment index for dynamic feedback according to various aspects of this disclosure are shown. In some examples, process flow 500 may implement various aspects of wireless communication system 100. For example, process flow 500 may include base station 105-b and UE 115-b, which may be examples of corresponding wireless devices as described herein. In the following description of process flow 500, operations between UE 115-b and base station 105-b may be transmitted in a different order than shown, or operations performed by UE 115-b and base station 105-b may be performed in a different order or at different times. Certain operations may be excluded from process flow 500, or other operations may be added to process flow 500. Although UE 115-b and base station 105-b are shown as performing operations of process flow 500, any wireless device may perform the operations shown. Furthermore, although Figure 5 An example of communication between UE 115-b and base station 105-b is shown, but the techniques described herein can be applied to communication between any number of wireless devices.

[0126] Base station 105-b and UE 115-b can communicate using one or more cells and / or component carriers (such as serving cell, primary cell, secondary cell, or some combination thereof, and other examples). During monitoring periods, base station 105-b can send control information to UE 115-b to schedule transmissions for UE 115-b. The control information can be sent on the serving cell (which may be referred to as the scheduling serving cell) and can be scheduled for transmissions for the serving cell or for one or more other serving cells (which may be referred to as the scheduled serving cells).

[0127] At point 505, base station 105-b may transmit first control information (e.g., first DCI) on a first serving cell (e.g., first scheduling serving cell) and second control information (e.g., second DCI) on a second serving cell (e.g., second scheduling serving cell) during a first monitoring opportunity (e.g., PMO). The first DCI and the second DCI may be scheduled for first and second transmissions (e.g., PDSCH, SPS release) for a third serving cell (e.g., first scheduled serving cell), respectively. In some aspects, the third serving cell may be the first serving cell; that is, both the first and second serving cells may be scheduled for transmissions used in the first serving cell. Alternatively, the third serving cell may be different from the first and second serving cells.

[0128] In some cases, the first and second serving cells can be the same. In some examples, the first serving cell can be the primary cell, and the second serving cell can be the secondary cell. In some aspects, the first transmission can be scheduled by a first DCI and a second DCI transmitted respectively on the first and second serving cells.

[0129] In some examples, base station 105-b may transmit third control information (e.g., third DCI) on the first serving cell during the same monitoring period. In some cases, the third DCI is scheduled for a third transmission on the third serving cell, while in others, the third DCI is scheduled for a third transmission on the fourth serving cell (e.g., the second scheduled serving cell).

[0130] In some examples, at 510, base station 105-b may transmit a third DCI during a second monitoring period different from the first monitoring period. The second monitoring period may occur after the first monitoring period.

[0131] At point 515, base station 105-b can transmit and UE 115-b can receive transmissions scheduled by DCI on the corresponding serving cell.

[0132] At 520, UE 115-b can identify the start time for the scheduled transmission. For example, UE 115-b can identify a first start time for a first transmission and a second start time for a second transmission.

[0133] At 525, in some examples, UE 115-b can identify an index associated with each serving cell. UE 115-b can identify a first index associated with a first serving cell, a second index associated with a second cell, and a third index associated with a third serving cell. If UE 115-b receives a third DCI scheduled for a third transmission in a fourth serving cell, UE 115-b can optionally identify a fourth index of the fourth serving cell (e.g., scheduled by the third DCI).

[0134] At 530, UE 115-b can determine the order of assignment indicator values ​​(e.g., DAI values) associated with HARQ / ACK feedback for scheduled transmissions based on the start time identified at 520, the index identified at 525, the corresponding monitoring timing, or some combination thereof. UE 115-b can determine the order between a first DAI value for a first transmission and a second DAI value for a second transmission based on the start time of the respective transmission. In some examples, a lower DAI value may correspond to an earlier start time (e.g., a transmission with an earlier start time may be ranked lower in the order).

[0135] When UE 115-b receives a third DCI scheduling a third transmission, UE 115-b can determine at 530 the order of the DAI values ​​used in the third transmission relative to other DAI values ​​in the feedback message. In some examples, UE 115-b can determine the order of the DAI values ​​based on the start time of the third transmission, for example, in the same manner as UE 115-b sorts the DAI values ​​of the first and second transmissions. Alternatively, UE 115-b can determine the order of the DAI values ​​based on an index identified at 525. For example, UE 115-b can determine the order of the DAI values ​​based on the index of the serving cell scheduled by the third DCI (e.g., the third index identified at 525) and / or the index of the serving cell scheduled by the first and second DCIs (e.g., the fourth index identified at 525). The DAI values ​​can be sorted in ascending order of the serving cell index, such that lower DAI values ​​correspond to lower serving cell index values.

[0136] If UE 115-b receives the third DCI during the second monitoring time, UE 115-b may determine the order of the DAI value for the third transmission relative to other DAI values ​​in the feedback message based on the second monitoring time that occurs after the monitoring time. For example, the higher DAI value corresponds to the second monitoring time that occurs after the first monitoring time (and the lower DAI value of the first and / or second transmission corresponds to the first monitoring time that occurs before the second monitoring time).

[0137] At position 535, UE 115-b can send feedback information to base station 105-b for at least the first and second transmissions based on the DAI values ​​ordered at position 530. The feedback information may include HARQ / ACK or HARQ / NACK for each transmission. In some examples, the feedback information can be sent on the PUCCH.

[0138] Figure 6 A block diagram 600 of a device 605 supporting an assignment index for dynamic feedback, according to various aspects of this disclosure, is shown. Device 605 may be an example of various aspects of a UE 115 as described herein. Device 605 may include a receiver 610, a transmitter 615, and a communications manager 620. Device 605 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0139] Receiver 610 may provide a unit for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels associated with assignment indices for dynamic feedback). The information may be transmitted to other components of device 605. Receiver 610 may utilize a single antenna or a collection of antennas.

[0140] Transmitter 615 may provide a unit for transmitting signals generated by other components of device 605. For example, transmitter 615 may transmit information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels associated with assignment indices for dynamic feedback). In some examples, transmitter 615 may be co-located with receiver 610 in a transceiver module. Transmitter 615 may utilize a single antenna or a collection of multiple antennas.

[0141] The communication manager 620, receiver 610, transmitter 615, or various combinations thereof, or various components thereof, may be examples of units for performing various aspects of the assignment index for dynamic feedback as described herein. For example, the communication manager 620, receiver 610, transmitter 615, or various combinations thereof, or components thereof, may support methods for performing one or more of the functions described herein.

[0142] In some examples, the communication manager 620, receiver 610, transmitter 615, or various combinations or components thereof may be implemented in hardware (e.g., in communication management circuitry). The hardware may include a processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof configured to or otherwise support units for performing the functions described herein. In some examples, the processor and memory coupled to the processor may be configured to perform one or more of the functions described herein (e.g., by executing instructions stored in memory by the processor).

[0143] Alternatively or concurrently, in some examples, the communication manager 620, receiver 610, transmitter 615, or various combinations or components thereof may be implemented using code executed by a processor (e.g., as communication management software or firmware). If implemented using processor-executed code, the functionality of the communication manager 620, receiver 610, transmitter 615, or various combinations or components thereof may be performed by a general-purpose processor, DSP, central processing unit (CPU), ASIC, FPGA, or any combination of these or other programmable logic devices (e.g., a unit configured or otherwise supported for performing the functions described in this disclosure).

[0144] In some examples, the communication manager 620 may be configured to use or otherwise cooperate with the receiver 610, transmitter 615, or both to perform various operations (e.g., receiving, monitoring, transmitting). For example, the communication manager 620 may receive information from the receiver 610, send information to the transmitter 615, or integrate with the receiver 610, transmitter 615, or both to receive information, send information, or perform various other operations as described herein.

[0145] According to the examples disclosed herein, the communication manager 620 can support wireless communication at the UE. For example, the communication manager 620 can be configured or otherwise supported to receive first control information on a first serving cell and second control information on a second serving cell during a monitoring period, wherein the first control information is scheduled for a first transmission in a third serving cell and indicates a first assignment indicator value associated with the first transmission, and the second control information is scheduled for a second transmission in the third serving cell and indicates a second assignment indicator value associated with the first transmission. The communication manager 620 can be configured or otherwise supported to identify a first index associated with the first serving cell for transmitting the first control information and a second index associated with the second serving cell for transmitting the second control information. The communication manager 620 can be configured or otherwise supported to determine the order between the first assignment indicator value for the first transmission and the second assignment indicator value for the second transmission based on the first index of the first serving cell for transmitting the first control information and the second index of the second serving cell for transmitting the second control information, the first assignment indicator value and the second assignment indicator value being associated with hybrid automatic repeat request acknowledgment feedback.

[0146] Alternatively or additionally, according to the examples disclosed herein, the communication manager 620 may support wireless communication at the UE. For example, the communication manager 620 may be configured or otherwise supported to receive first control information on a first serving cell and second control information on a second serving cell during a monitoring period, wherein the first control information is scheduled for a first transmission in a third serving cell and indicates a first assignment indicator value associated with the first transmission, and the second control information is scheduled for a second transmission in the third serving cell and indicates a second assignment indicator value associated with the first transmission. The communication manager 620 may be configured or otherwise supported to identify a first start time for the first transmission and a second start time for the second transmission. The communication manager 620 may be configured or otherwise supported to determine the order between the first assignment indicator value for the first transmission and the second assignment indicator value for the second transmission based on the first start time for the first transmission and the second start time for the second transmission, wherein the first assignment indicator value and the second assignment indicator value are associated with hybrid automatic repeat request acknowledgment feedback.

[0147] By including or configuring the communication manager 620 according to the examples described herein, device 605 (e.g., a processor that controls or is otherwise coupled to receiver 610, transmitter 615, communication manager 620, or a combination thereof) can support techniques for assigning assignment indicator values ​​when different scheduled cells in the same scheduled cell schedule transmissions at the same monitoring time. Therefore, device 605 can group feedback for transmissions into common feedback messages, which can provide more efficient utilization of communication resources at device 605.

[0148] Figure 7 A block diagram 700 of a device 705 supporting an assignment index for dynamic feedback, according to various aspects of this disclosure, is shown. Device 705 may be an example of aspects of device 605 or UE 115 as described herein. Device 705 may include a receiver 710, a transmitter 715, and a communication manager 720. Device 705 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0149] Receiver 710 may provide a unit for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels associated with assignment indices for dynamic feedback). Information may be transmitted to other components of device 705. Receiver 710 may utilize a single antenna or a collection of multiple antennas.

[0150] Transmitter 715 may provide a unit for transmitting signals generated by other components of device 705. For example, transmitter 715 may transmit information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels associated with assignment indices for dynamic feedback). In some examples, transmitter 715 may be co-located with receiver 710 in a transceiver module. Transmitter 715 may utilize a single antenna or a collection of multiple antennas.

[0151] Device 705 or its various components may be examples of units for performing various aspects of assignment indexing for dynamic feedback as described herein. For example, communication manager 720 may include control information receiver 725, index identification component 730, assignment indicator value component 735, start time identification component 740, or any combination thereof. Communication manager 720 may be examples of various aspects of communication manager 620 as described herein. In some examples, communication manager 720 or its various components may be configured to use receiver 710, transmitter 715, or both, or otherwise cooperate with receiver 710, transmitter 715, or both to perform various operations (e.g., receiving, monitoring, transmitting).
