[0065] Some wireless communication systems may include communication devices, such as user equipment (UE) and base stations (e.g., evolved Node B (eNB), next generation Node B, or Gigabit Node B (any of which may be referred to as gNB)) that may support multiple radio access technologies. Examples of radio access technologies include 4G systems (such as long term evolution (LTE) systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). In some examples, the communication device may support one or more of the above example radio access technologies. Channel state information resources may be measured by a UE to estimate the channel quality between a base station and the UE, where the channel quality may be indicated by measured parameters (e.g., a channel quality indicator, a precoding matrix indicator, a rank indicator, a layer 1 reference signal received power). The UE may transmit a channel state information report to the base station indicating channel quality information that the base station can use for data transmission. The base station may use the report for scheduling in the future. However, conventional channel state information reporting techniques may have defects.
[0066] In an existing wireless communication system, a transmission order associated with multiple acknowledgements may be specified for a UE and a base station. Specifically, a UE may receive a first downlink grant and may determine a first acknowledgement associated with the first downlink grant. The UE may then additionally receive a second downlink grant and may determine a second acknowledgement associated with the second downlink grant. In some cases, the UE may determine the first acknowledgement after receiving the second grant. In some wireless communication systems, a UE may identify a configuration indicating a transmission order associated with the first acknowledgement and the second acknowledgement. For example, the UE may determine that the second acknowledgement associated with the second downlink grant may not be transmitted in a time slot or sub-time slot earlier than the time slot used to transmit the first acknowledgement associated with the first downlink grant. Current wireless communication systems may allow downlink grants to trigger a non-periodic channel state information report on a physical uplink control channel. Therefore, there is a need to define the order of multiple non-periodic channel state information triggered by multiple grants, etc.
[0067] One or more aspects of the present disclosure address, among other aspects, implementing one or more rules to efficiently define the ordering of multiple aperiodic channel state information reports triggered by multiple downlink or downlink and uplink grants. In some examples, a UE may receive a first downlink grant that triggers a first aperiodic channel state information report. The UE may also receive a second downlink grant that triggers a second aperiodic channel state information report. In some cases, the UE may receive the first grant before receiving the second grant. The UE may determine a transmission order based on a rule (such as a configuration or pre-configured rule received from a base station), and may then transmit the first aperiodic channel state information report and the second aperiodic channel state information report based on the transmission order.
[0068] Aspects of the disclosure are initially described in the context of wireless communication systems. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to transmission order determination for aperiodic channel state information.
[0069] Figure 1 An example of a wireless communication system 100 supporting transmission order determination for non-periodic channel state information according to various aspects of the present disclosure is illustrated. 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.
[0070] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may be different forms of devices or devices 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.
[0071] UEs 115 may be dispersed throughout the wireless communication system 100, and each UE 115 may be stationary or mobile. UE 115 may also be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client. UE 115 may be a device such as a cellular phone, a smart phone, a personal digital assistant (PDA), a multimedia / entertainment device (e.g., a radio, an MP3 player, a video device, etc.), a camera, a gaming device, a navigation / positioning device (e.g., a GNSS (Global Navigation Satellite System) device based on, for example, GPS (Global Positioning System), BeiDou, GLONASS or Galileo, ground-based devices, etc.), a tablet computer, a laptop computer, a netbook, a smartbook, a personal computer, a smart device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, virtual reality goggles, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet)), a drone, a robot / robotic device, a vehicle, a vehicle device, a meter (e.g., a parking meter, an electric meter, a gas meter, a water meter), a monitor, a gas pump, an appliance (e.g., a kitchen appliance, a washing machine, a dryer), a location tag, a medical / health care device, an implant, a sensor / actuator, a display, or any other suitable device configured to communicate via a wireless or wired medium. In some examples, UE 115 may also refer to a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, etc., which may be implemented in various items (such as appliances, drones, robots, vehicles, instruments, etc.).
[0072] 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 communication from devices that integrate sensors or meters to measure or capture information and relay the information to a central server or application, which may utilize the information or present the information to a person interacting with the program or application. Some UEs 115 may be designed to collect information or implement automated behavior of machines. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging. In one aspect, the technology disclosed herein may be applicable to MTC or IoT UEs. MTC or IoT UE may include MTC / enhanced MTC (eMTC, also known as CAT-M, Cat M1) UE, NB-IoT (also known as CAT NB1) UE, and other types of UE. eMTC and NB-IoT may refer to future technologies that may evolve from or be based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (further enhanced eMTC), mMTC (massive MTC), etc., and NB-IoT may include eNB-IoT (enhanced NB-IoT), FeNB-IoT (further enhanced NB-IoT), etc.
[0073] Each base station 105 may communicate with the core network 130, or communicate with each other, or both. For example, the base station 105 may interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate with each other directly (e.g., directly between the base stations 105), or indirectly (e.g., via the core network 130), or directly and indirectly on the backhaul link 120 (e.g., via X2, Xn, or other interfaces). In some examples, the backhaul link 120 may be or include one or more wireless links.
[0074] One or more of the base stations 105 described herein may include or may be referred to by a person of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a B node, an evolved B node (eNB), a next generation B node or a gigabit B node (any of which may be referred to as a gNB), a home B node, a home evolved B node, or other suitable terminology.
[0075] The 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, where "device" may also be referred to as a unit, station, terminal, or client, etc. The 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, the 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, etc., which may be implemented in various objects such as appliances, vehicles, meters, etc.
[0076] The UE 115 described herein may be capable of communicating with various types of devices, such as other UE 115s that may sometimes act as relays, as well as base station 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc., as Figure 1 shown.
[0077] The UE 115 and the base station 105 may wirelessly communicate with each other via one or more communication links 125 over one or more carriers. The term "carrier" may refer to a set of radio frequency spectrum resources that has a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion (e.g., bandwidth part (BWP)) of a radio frequency spectrum band 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 for coordinating carrier operation, user data, or other signaling. The wireless communication system 100 may support communicating with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used in conjunction with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.
[0078] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling for coordinating the operation of other carriers. A carrier may be associated with a frequency channel (e.g., evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN)) and may be positioned according to a channel raster for discovery by the UE 115. A carrier may operate in a stand-alone mode in which initial acquisition and connection may be performed by the UE 115 via the carrier, or a carrier may operate in a non-stand-alone mode in which the connection is anchored using a different carrier (e.g., different carriers of the same or different radio access technologies).
[0079] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in an FDD mode), or may be configured to carry both downlink and uplink communications (e.g., in a TDD mode).
[0080] 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 several determined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)) of a carrier of a particular radio access technology. Devices (e.g., base stations 105, UEs 115, or both) of the wireless communication system 100 may have a hardware configuration that supports communications on a particular carrier bandwidth, or may be configurable to support communications on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., subband, BWP) or all of a carrier bandwidth.
[0081] The signal waveform transmitted on the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system using MCM technology, a resource element may include a code element period (e.g., the duration of a modulation code element) and a subcarrier, where the code element period and the subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the code rate of the modulation scheme, or both). Thus, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 can be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further improve the data rate or data integrity of communication with UE 115.
[0082] One or more parameter designs for a carrier may be supported, where the parameter designs may include subcarrier spacing (Δf) and cyclic prefixes. A carrier may be divided into one or more BWPs with the same or different parameter designs. 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 the one or more active BWPs.
[0083] The time interval of the base station 105 or the UE 115 can be expressed as a multiple of a basic time unit, and the basic time unit can be, for example, a sampling period T s =1 / (Δf max ·Nf) seconds, where Δf max Nf may represent the maximum supported subcarrier spacing, and Nf may represent the maximum supported discrete Fourier transform (DFT) size. Time intervals of communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).
[0084] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be 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 code element periods (e.g., depending on the length of the cyclic prefix added before each code element period). In some wireless communication systems 100, the time slot may be further divided into a plurality of mini-time slots containing one or more code elements. Excluding the cyclic prefix, each code element period may include one or more (e.g., Nf) sampling periods. The duration of the code element period may depend on the subcarrier spacing or the operating frequency band.
[0085] 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 bursts of shortened TTIs (sTTIs)).
[0086] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, for example, using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a number of symbol periods and may extend across a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .
[0087] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have service subscriptions with a network provider that supports the macro cell. A small cell may be associated with a lower power base station 105 (compared to a macro cell), 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 UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A base station 105 may support one or more cells and may also support communications on one or more cells using one or more component carriers.
[0088] 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.
[0089] 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.
[0090] 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 or asynchronous operation.
[0091] 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 unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed with a reduced peak rate. Other power saving techniques for UE 115 include entering a power saving deep sleep mode when not engaged in active communications, operating on a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is 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 a carrier.
[0092] The wireless communication system 100 may be configured to support ultra-reliable communication or low latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low latency communication (URLLC) or mission-critical communication. UE 115 may be designed to support ultra-reliable, low latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private communication or group communication, and may be supported by one or more mission-critical services (such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions may include prioritization of services, and mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low latency, critical mission, and ultra-reliable low latency may be used interchangeably herein.
[0093] In some examples, UE 115 may also be able to communicate directly with other UE 115 over 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 a geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105, or may not be able to receive transmissions from the base station 105 for other reasons. In some examples, each group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, wherein 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 each UE 115 without involving the base station 105.
[0094] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), and the EPC or 5GC 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 interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by a base station 105 associated with the core network 130. User IP packets may be delivered via 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. Operator IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.
[0095] Some network devices (such as base stations 105) may include subcomponents, such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with each UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or merged into a single network device (e.g., base station 105).
[0096] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). In general, the 300 MHz to 3 GHz region is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from about 1 decimeter to 1 meter long. UHF waves may be blocked or redirected by buildings and environmental features, but these waves may penetrate various structures sufficiently for macro cells to provide service to UEs 115 located indoors. Transmissions using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.
[0097] The wireless communication system 100 may also operate in a super high frequency (SHF) zone using a frequency band from 3 GHz to 30 GHz (also known as a centimeter band) or in an extremely high frequency (EHF) zone of a spectrum (e.g., from 30 GHz to 300 GHz) (also known 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 antenna of the corresponding device may be smaller and more closely spaced than the UHF antenna. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein may be adopted across transmissions using one or more different frequency zones, and the use of frequency bands specified across these frequency zones may vary by country or regulatory agency.
[0098] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band (such as the 5 GHz industrial, scientific, and medical (ISM) band). When operating in an unlicensed radio frequency spectrum band, devices (such as base stations 105 and UEs 115) may employ carrier sensing for conflict detection and avoidance. In some examples, operations in an unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in coordination with component carriers operating in a licensed band. Operations in an unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.
[0099] The base station 105 or UE 115 may be equipped with multiple antennas, which can 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 in one or more antenna arrays or antenna panels that can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having antenna ports of several rows and columns that the base station 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.
[0100] The base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such technology may be referred to as spatial multiplexing. For example, the transmitting device may transmit multiple signals via different antennas or different antenna combinations. Similarly, the receiving device may receive multiple signals via different antennas or different antenna combinations. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.
[0101] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to shape 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 may be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each antenna element may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).
[0102] The base station 105 or the UE 115 may use beam sweeping techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the base station 105 in different directions. For example, the base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device (such as the base station 105) or a receiving device (such as the UE 115)) to identify a beam direction used by the base station 105 for later transmission or reception.
[0103] Some signals, such as data signals associated with a particular recipient device, may be transmitted by base station 105 in a single beam direction, e.g., a direction associated with a recipient device, such as UE 115. In some examples, a beam direction associated with transmissions along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.
[0104] In some examples, transmission by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from the base station 105 to the UE 115). The UE 115 may report feedback indicating precoding weights 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 transmit a reference signal that may be precoded or uncoded (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)). The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may use similar techniques to transmit signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).
[0105] A receiving device (e.g., UE 115) may try multiple reception configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a base station 105. For example, the receiving device may try multiple reception directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets (e.g., different directional 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, the receiving device may use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). The 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).
[0106] 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 of 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 media access control (MAC) layer may perform priority handling and multiplex logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmission of 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 of user plane data between UE 115 and base station 105 or core network 130. In the physical layer, transport channels may be mapped to physical channels.
[0107] UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood that data is correctly received on communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve the throughput of the MAC layer in poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support simultaneous slot HARQ feedback, wherein the device may provide HARQ feedback in a specific 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.
[0108] In some wireless communication systems, a transmission order associated with multiple acknowledgements may be statically specified for a UE and a base station. In some cases, a UE may identify a configuration indicating a transmission order associated with a first acknowledgement associated with a first downlink grant and a second acknowledgement associated with a second downlink grant. The transmission order may indicate that the second acknowledgement associated with the second downlink grant may not be transmitted in a time slot or sub-time slot earlier than the time slot used to transmit the first acknowledgement associated with the first downlink grant. Such wireless communication systems may allow downlink grants to trigger non-periodic channel state information reports on a physical uplink control channel. Therefore, there is a need for defining the order of multiple non-periodic channel state information triggered by multiple grants and other conditions, etc.
[0109] One or more aspects of the present disclosure address implementing one or more rules to efficiently define the ordering of multiple aperiodic channel state information reports triggered by multiple downlink or downlink and uplink grants, and other aspects. In some examples, UE 115 may receive a first downlink grant that triggers a first aperiodic channel state information report and a second downlink grant that triggers a second aperiodic channel state information report. UE 115 may determine a transmission order based on a configuration received from base station 105. UE 115 may then transmit the first aperiodic channel state information report and the second aperiodic channel state information report based on the transmission order.
[0110] Figure 2An example of a wireless communication system 200 that supports transmission order determination for non-periodic channel state information according to various aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 may implement various aspects of the wireless communication system 100. The wireless communication system 200 may include a base station 105-a and a UE 115-a within a geographic coverage area 110-a. The base station 105-a and the UE 115-a may be examples of a base station 105 and a UE 115 as described herein. In some examples, the wireless communication system 200 may support multiple radio access technologies, including a 4G system (such as an LTE system, an LTE-A system, or an LTE-APro system), and a 5G system (which may be referred to as an NR system or an NR communication system). In some examples, the wireless communication system 200 may implement various aspects of the wireless communication system 100 to support improvements in power consumption, spectral efficiency, higher data rates, and in some examples, may promote enhanced efficiency of high reliability and low latency communication operations, and other benefits.
[0111] According to one or more aspects of the present disclosure, UE 115 may implement one or more rules to efficiently define the ordering of multiple non-periodic channel state information reports triggered by multiple downlink grants. For example, UE 115-a may be configured by base station 105-a to implement one or more rules, and UE 115-a may implement one or more rules for the transmission order of channel state information reports. In some cases, UE 115-a may identify one or more rules from a predefined configuration (such as, a configuration defined for multiple UEs), and may implement the one or more rules to identify the transmission order of multiple non-periodic channel state information reports. Additionally or alternatively, other wireless devices (such as base station 105-a) may implement one or more rules described herein for improved efficiency and data throughput of system communications, among other benefits.
[0112] The base station 105-a may transmit a channel state information reference signal within one or more channel state information resources for measurement by the UE 115-a to estimate the channel quality between the base station 105-a and the UE 115-a. The UE 115-a may transmit a channel state information report to the base station indicating channel quality information that the base station 105 may use, for example, to schedule subsequent data transmissions.
[0113] In some wireless communication systems, a channel state information report may be requested by a base station using a downlink grant. For example, a UE (such as UE 115-a) may receive a downlink grant and may further receive one or more downlink control information messages (e.g., in a physical downlink shared channel, a physical downlink control channel, etc.), wherein each downlink control information message may include an associated physical uplink shared channel for transmitting an uplink message scheduled by the downlink control information message. In one or more wireless communication systems, a UE may determine an acknowledgement associated with a downlink grant. In some aspects, an acknowledgement report may be associated with a timeline. That is, a UE may receive a downlink grant and may determine an offset (e.g., K0=0 or K0=non-zero value), which may indicate a gap between a downlink grant and a physical downlink shared channel. Additionally or alternatively, the UE may determine a second offset (K1), which may indicate to the UE when to report an acknowledgement or negative acknowledgement associated with a physical downlink shared channel to the base station.
[0114] In some examples, the base station may use the reported acknowledgement or negative acknowledgement to perform link adaptation and other operations. In an existing wireless communication system, an order associated with multiple acknowledgements or negative acknowledgements may be specified for the UE and the base station. Specifically, the UE may receive a first downlink grant and may determine a first acknowledgement (e.g., HARQ-ACK) associated with the first downlink grant. The UE may then receive a second downlink grant and may determine a second acknowledgement associated with the second downlink grant. According to the existing configuration, the UE may determine that the second acknowledgement associated with the second downlink grant may not be transmitted in a time slot or sub-time slot earlier than the time slot for the first acknowledgement associated with the first downlink grant. In some examples, the first acknowledgement associated with the first downlink grant and the second acknowledgement associated with the second downlink grant may be scheduled in the same time slot. If the first acknowledgement associated with the first downlink grant and the second acknowledgement associated with the second downlink grant are scheduled in the same time slot, the UE may multiplex the first acknowledgement and the second acknowledgement in one physical uplink control channel.
[0115] Additionally or alternatively, a UE (such as UE 115-a) may receive multiple uplink grants and may identify an associated physical uplink shared channel for transmitting an uplink message scheduled by the uplink grant. In some examples, the UE may measure a channel state and may transmit a channel state information report. According to one or more aspects, the channel state information may be included in a physical uplink shared channel, for example, as a semi-static report. In some examples, an order associated with multiple physical uplink shared channels may be specified for the UE and the base station. For example, the UE may receive a first uplink grant and may identify a first physical uplink shared channel associated with the first uplink grant. The UE may then receive a second uplink grant after receiving the first uplink grant. The UE may identify a second physical uplink shared channel associated with the second uplink grant. In some aspects, the UE and the base station may be configured such that a second physical uplink shared channel scheduled by a second uplink grant (i.e., an uplink grant received later in time) cannot start before the end symbol of the first physical uplink shared channel scheduled by the first uplink grant.
[0116] In some wireless communication systems, channel state information or channel quality indicator information feedback may be based on periodic channel state information feedback or aperiodic channel state information feedback. In some examples, periodic channel state information feedback may not be flexible and may be associated with a periodic value. Additionally or alternatively, the timeline associated with aperiodic channel state information feedback may be different from the timeline associated with an acknowledgment or negative acknowledgment transmission. That is, the UE may not transmit aperiodic channel state information in the same time slot as the acknowledgment. In some examples, the channel state information may be included in the channel state information report. Current wireless communication systems supporting NR communication may provide downlink grants to trigger aperiodic channel state information reports on a physical uplink control channel. In some examples, the UE may receive multiple downlink grants that trigger multiple aperiodic channel state information reports. Therefore, there is a need to define the order of different aperiodic channel state information reports on the PUCCH physical uplink control channel triggered by multiple downlink grants.
[0117] According to one or more aspects of the present disclosure, UE 115-a may receive (e.g., from base station 105-a) a first downlink grant 210-a that triggers a first aperiodic channel state information report 215-a and a second downlink grant 210-b that triggers a second aperiodic channel state information report 215-b. Figure 2As depicted in the example of , UE 115-a may receive a second downlink grant 210-b after receiving a first downlink grant 210-a. In some aspects, UE 115-a may determine a transmission order based on a rule, such as a configuration transmitted by base station 105-a or a configuration otherwise identified by UE 115-a. The rule may be based on UE capabilities. For example, UE 115-a may transmit UE capability information indicating the ability of UE 115-a to support transmission order. That is, UE 115-a may indicate to base station 105-a that UE 115-a can support out-of-order transmissions. Based on the UE capability information, base station 105-a may identify one or more rules, and may include one or more rules in a configuration message. UE 115-a may receive a configuration message from base station 105-a, and may identify a transmission order for transmitting multiple non-periodic channel state information reports. In some cases, the channel state information report may include channel state information. In some examples, the transmission order may define whether out-of-order transmission of the aperiodic channel state information report is possible for UE 115-a. Upon determining the transmission order, UE 115-a may transmit the first aperiodic channel state information report 215-a and the second aperiodic channel state information report 215-b according to the transmission order. Figure 2 As depicted in the example of , UE 115-a may determine that out-of-sequence transmission of non-periodic channel state information reports is not allowed for UE 115-a. In this case, UE 115-a may transmit a first non-periodic channel state information report 215-a before transmitting a second non-periodic channel state information report 215-b.
[0118] Figure 3 An example of a configuration 300 that supports transmission order determination for non-periodic channel state information according to aspects of the present disclosure is illustrated. In some examples, the configuration 300 may implement reference Figure 1 The wireless communication system 100 described herein and the reference Figure 2 Configuration 300 may be an example of a UE transmitting a first type of aperiodic channel state information (eg, type 1 aperiodic channel state information). Figure 3 In an example of FIG. 3 , configuration 300 illustrates a procedure for communicating according to a configuration of a transmission order of multiple non-periodic channel state information (such as non-periodic channel state information reports) in response to multiple downlink grants received at a UE from a base station, the UE and the base station may be referenced Figure 1 Examples of corresponding devices described.
[0119] In some aspects, the first type of aperiodic channel state information may include transmission of joint channel state information (such as aperiodic channel state information) and an acknowledgment report on a physical uplink control channel. For example, a UE (such as UE115) may receive a downlink grant, and the UE may identify that the downlink grant triggers an aperiodic channel state information report. The UE may determine an acknowledgment associated with the downlink grant, and may jointly transmit the aperiodic channel state information report and the acknowledgment in a physical uplink control channel. According to one or more aspects of the present disclosure, in the case of type 1 aperiodic channel state information transmission, if the UE was previously scheduled by a prior downlink grant to transmit a joint acknowledgment and an aperiodic channel state information report on time slot i, the UE may not be expected to report the joint acknowledgment and an aperiodic channel state information report triggered by a later downlink grant in time slot j<i.
[0120] like Figure 3 As depicted in the example of , the UE may receive a first downlink grant 305 including an indication that first channel state information is to be reported, and may receive a second downlink grant 320 including an indication that second channel state information is to be reported. In this example, the UE may receive the second downlink grant 320 after the first downlink grant 305. The UE may identify a first physical downlink shared channel 310 associated with the first downlink grant 305 and a second physical downlink shared channel 325 associated with the second downlink grant 320. In some examples, the UE may identify that the first channel state information and the second channel state information are associated with a first aperiodic channel state information type (or a type 1 aperiodic channel state information transmission). Based on receiving the first physical downlink shared channel 310 associated with the first downlink grant 305, the UE may identify a first acknowledgement. Additionally, the UE may identify a second acknowledgement based on the second physical downlink shared channel 325 associated with the second downlink grant 320. According to one or more aspects of the present disclosure, the UE may determine a transmission order based on a configuration received from a base station or a configuration otherwise determined by the UE. In some examples, the transmission order may be associated with the joint transmission of the first aperiodic channel state information and the first acknowledgment 315 and the joint transmission of the second aperiodic channel state information and the second acknowledgment 330 .
[0121] In some examples, the configuration may indicate that the first aperiodic channel state information and the first acknowledgment (i.e., joint transmission 315) are to be transmitted in a first time slot, and the second aperiodic channel state information and the second acknowledgment (i.e., joint transmission 330) are to be transmitted in a second time slot, the first time slot being no later than the second time slot. Figure 3As depicted in the example of , the UE may determine that the joint transmission 315 of the first non-periodic channel state information and the first acknowledgment is not allowed for the UE later (e.g., in a later time slot) than the joint transmission 330 of the second non-periodic channel state information and the second acknowledgment. That is, the UE may determine that the configuration may not allow the UE to transmit the second non-periodic channel state information and the second acknowledgment before the first non-periodic channel state information and the first acknowledgment. In some examples, the UE may transmit the first non-periodic channel state information and the second non-periodic channel state information according to the transmission order.
[0122] Figure 4 An example of a configuration 400 that supports transmission order determination for non-periodic channel state information according to aspects of the present disclosure is illustrated. In some examples, the configuration 400 may be implemented as described with reference to Figure 1 The wireless communication system 100 described herein and as described with reference to Figure 2 Configuration 400 may be an example of a UE transmitting a second type of aperiodic channel state information (eg, type 2 aperiodic channel state information). Figure 4 In an example of FIG. 4 , configuration 400 illustrates a procedure for communicating according to a configuration that facilitates a transmission order for multiple aperiodic channel state information (such as an aperiodic channel state information report) in response to multiple downlink grants received at a UE from a base station, the UE and the base station may be referenced Figure 1 Examples of corresponding devices described.
[0123] In some aspects, the second type of aperiodic channel state information may include a separate transmission of channel state information (such as aperiodic channel state information) and an acknowledgment report on a separate physical uplink control channel. In some examples, a UE (e.g., UE 115) may receive a downlink grant, and the UE may identify that the downlink grant triggers an aperiodic channel state information report. The UE may determine an acknowledgment associated with the downlink grant. The UE may transmit an acknowledgment in a first physical uplink control channel and transmit an aperiodic channel state information report in a second physical uplink control channel. That is, a UE configured with the second type of aperiodic channel state information may transmit a separate acknowledgment (e.g., HARQ-ACK) and a channel state information report on a corresponding physical uplink control channel.
[0124] According to one or more aspects of the present disclosure, in the case of type 2 aperiodic channel state information transmission, the acknowledgment and aperiodic channel state information triggered by one or more downlink grants may follow the same order. In some examples, a UE (such as UE 115) may receive a first downlink grant 405 including an indication that first channel state information 415 is to be reported. The UE may further receive a second downlink grant 420 including an indication that second channel state information 430 is to be reported. Figure 4 As depicted in the example of , the UE may receive the second downlink grant 420 after the first downlink grant 405. The UE may identify the first acknowledgment 410 associated with the first downlink grant 405 and the second acknowledgment 425 associated with the second downlink grant 420. In some examples, the UE may identify that the first channel state information 415 and the second channel state information 430 are associated with the second non-periodic channel state information type (or type 2 non-periodic channel state information transmission). In some examples, the UE may determine the transmission order based on a configuration received from the base station or a configuration otherwise determined by the UE. The configuration may indicate that the second acknowledgment 425 triggered by the second downlink grant 420 is allowed to be transmitted after the start codeword or the end codeword of the first channel state information 415 triggered by the first downlink grant 405.
[0125] In some examples, the UE may determine a start symbol associated with the transmission of the first channel state information 415. In some cases, the configuration may indicate that the second acknowledgment 425 will be transmitted no earlier than the start symbol associated with the transmission of the first channel state information 415. Additionally or alternatively, the UE may determine an end symbol associated with the transmission of the first channel state information 415. In such cases, the configuration may indicate that the second acknowledgment 425 will be transmitted no earlier than the end symbol associated with the transmission of the first channel state information 415. Thus, as Figure 4 As depicted in the example of , the configuration may not allow the UE to transmit the second acknowledgement 425 before transmitting the first channel state information 415.
[0126] Figure 5 An example of a configuration 500 that supports transmission order determination for non-periodic channel state information according to aspects of the present disclosure is illustrated. In some examples, the configuration 500 may implement reference Figure 1 The wireless communication system 100 described herein and the reference Figure 2 Configuration 500 may be an example of a UE transmitting a second type of aperiodic channel state information (eg, type 2 aperiodic channel state information). Figure 5In an example of FIG. 5 , configuration 500 illustrates a procedure for communicating according to a configuration that facilitates a transmission order of multiple non-periodic channel state information (such as, non-periodic channel state information reports) in response to multiple downlink grants received at a UE from a base station, the UE and the base station may be referenced Figure 1 Examples of corresponding devices described.
[0127] As described herein, the second type of aperiodic channel state information may include separate transmissions of channel state information (such as aperiodic channel state information) and an acknowledgment report on a separate physical uplink control channel. In some examples, a UE (e.g., UE 115) may receive a downlink grant, and the UE may identify that the downlink grant triggers an aperiodic channel state information report. The UE may determine an aperiodic channel state information report and an acknowledgment associated with the downlink grant. In an example of a type 2 aperiodic channel state information report transmission, the UE may transmit an acknowledgment in a first physical uplink control channel and transmit an aperiodic channel state information report in a second physical uplink control channel.
[0128] According to one or more aspects of the present disclosure, in the case of type 2 aperiodic channel state information transmission, one or more confirmations and one or more aperiodic channel state information triggered by one or more downlink grants may follow their respective orders. For example, a confirmation triggered by a second downlink grant (i.e., a downlink grant received after a first downlink grant) may not need to be received later than a non-periodic channel state information transmission triggered by the first downlink grant. That is, a configuration received or otherwise identified by a UE may indicate that for type 2 aperiodic channel state information transmission, aperiodic channel state information and confirmation transmissions for different grants may not be in order. However, the configuration may further indicate that aperiodic channel state information triggered by a later downlink grant may not be transmitted earlier than aperiodic channel state information triggered by a previous downlink grant.
[0129] As reference Figure 5As described, a UE (such as UE 115) may receive a first downlink grant 505 including an indication that first channel state information 515 is to be reported. The UE may also receive a second downlink grant 520 including an indication that second channel state information 530 is to be reported. In some examples, the UE may receive the second downlink grant 520 after the first downlink grant 505. The UE may identify a first acknowledgment 510 associated with the first downlink grant 505 and a second acknowledgment 525 associated with the second downlink grant 520. In some examples, the UE may identify that the first channel state information 515 and the second channel state information 530 are associated with a second non-periodic channel state information type (or type 2 non-periodic channel state information transmission). According to one or more aspects of the present disclosure, the UE may determine a transmission order based on a configuration received from a base station.
[0130] The configuration may indicate that the UE is not allowed to schedule the second non-periodic channel state information 530 earlier than the first non-periodic channel state information 515. For example, the configuration may indicate that the first channel state information 515 will be transmitted no later than the second channel state information 530. In some cases, the first channel state information 515 and the second channel state information 530 are transmitted in the same time slot. According to another example, the configuration may indicate that the UE is not allowed to schedule the second non-periodic channel state information 530 starting before the start codeword of the transmission of the first non-periodic channel state information 515. In some examples, the UE may determine the start codeword associated with the transmission of the first channel state information 515. In some cases, the UE may determine that the configuration indicates that the second channel state information 530 will be transmitted no earlier than the start codeword associated with the transmission of the first channel state information 515.
[0131] Additionally or alternatively, the configuration may indicate that the UE is not allowed to schedule the second non-periodic channel state information 530 earlier than the end symbol of the first non-periodic channel state information 515. For example, the UE may determine the end symbol associated with the transmission of the first channel state information 515. In some cases, the configuration may indicate that the second channel state information 530 will not be transmitted earlier than the end symbol associated with the transmission of the first channel state information 515. Additionally or alternatively, the configuration may indicate that the UE is not expected to be scheduled to transmit two non-periodic channel state information reports on the physical uplink control channel in the same time slot. That is, the configuration may indicate that the second non-periodic channel state information 530 will be transmitted in a later time slot than the first non-periodic channel state information 515. For example, the configuration may indicate that the first channel state information will be transmitted in a first time slot, and the second channel state information will be transmitted in a second time slot, the first time slot being earlier than the second time slot. In some examples, the configuration may indicate that the second acknowledgement 525 associated with the second downlink grant 520 is allowed to be scheduled earlier than the first channel state information 515.
[0132] like Figure 5 As described in the example of , the UE may determine a transmission order of the first non-period channel state information 515 and the second non-period channel state information 530, and the UE may transmit the first non-period channel state information 512 and the second non-period channel state information 630 according to the transmission order.
[0133] Fig. 6A and 6B Examples of configurations 600 and 650 that support transmission order determination for aperiodic channel state information according to aspects of the present disclosure are illustrated. In some examples, configurations 600 and 650 may implement reference Figure 1 The wireless communication system 100 described herein and the reference Figure 2 Various aspects of the wireless communication system 200 described herein. Configuration 600 and configuration 650 may be examples of a UE transmitting a second type of aperiodic channel state information (eg, type 2 aperiodic channel state information). Fig. 6A and 6B In an example of , configurations 600 and 650 may illustrate procedures for communicating according to one or more configurations that facilitate a transmission order of multiple non-periodic channel state information (such as, non-periodic channel state information reports) in response to multiple downlink grants received at a UE from a base station, the UE and the base station may be referenced Figure 1 Examples of corresponding devices described.
[0134] According to one or more aspects of the present disclosure, one or more channel state information reference signals and one or more non-periodic channel state information triggered by one or more downlink grants may follow a transmission order. Fig. 6AIn an example of , a UE (such as UE 115) may receive a first downlink grant 605 including an indication that first channel state information 615 (such as aperiodic channel state information) is to be reported. The UE may also receive a second downlink grant 620 including an indication that second channel state information 630 is to be reported. In some examples, the UE may receive the second downlink grant 620 after the first downlink grant 605. The UE may also receive a first channel state information reference signal 610 associated with the first downlink grant 605 and a second channel state information reference signal 625 associated with the second downlink grant 620. In some examples, the UE may determine the transmission order based on a configuration received from a base station or a configuration otherwise identified by the UE. The configuration may indicate that the channel state information reference signal 625 triggered by the second downlink grant 620 is not allowed to be received earlier than the channel state information reference signal 610 triggered by the first downlink grant 605. The configuration may further indicate that the channel state information reference signal 625 triggered by the second downlink grant 620 may not be in sequence with the non-periodic channel state information 615 (such as a channel state information report) triggered by the first downlink grant 605. For example, the configuration may indicate that the first channel state information reference signal 610 is allowed to be received earlier than the second channel state information reference signal 625. Additionally or alternatively, the configuration may indicate that the first channel state information 615 is allowed to be transmitted earlier than the reception of the second channel state information reference signal 625 (not shown). In some examples, the configuration may indicate that the second channel state information reference signal 625 is allowed to be received earlier than the transmission of the first channel state information 615.
[0135] exist Figure 6B In an example of , the UE may receive a first downlink grant 655 including an indication that first channel state information 665 (such as aperiodic channel state information) is to be reported. The UE may also receive a second downlink grant 670 including an indication that second channel state information 680 is to be reported. In some examples, the UE may receive the second downlink grant 670 after the first downlink grant 655. The UE may receive a first channel state information reference signal 660 associated with the first downlink grant 655 and a second channel state information reference signal 675 associated with the second downlink grant 670. In some examples, the UE may determine the transmission order based on a configuration received from a base station or a configuration otherwise identified by the UE. According to one or more aspects of the present disclosure, the configuration may indicate that the second channel state information reference signal 675 triggered by the second downlink grant 670 may not be received earlier than the first channel state information report 665 (or aperiodic channel state information report) triggered by the first downlink grant 655.
[0136] Fig. 7A and 7B Examples of configurations 700 and 750 that support transmission order determination for non-periodic channel state information according to aspects of the present disclosure are illustrated. In some examples, configurations 700 and 750 may implement reference Figure 1 The wireless communication system 100 described herein and the reference Figure 2 Various aspects of the wireless communication system 200 are described. Fig. 7A and 7B In an example of FIG. 7 , configurations 700 and 750 may illustrate procedures for communicating according to one or more configurations that facilitate a transmission order of multiple non-periodic channel state information (such as, non-periodic channel state information reports) in response to multiple downlink grants received at a UE from a base station, the UE and the base station may be referenced Figure 1 Examples of corresponding devices described.
[0137] exist Fig. 7AIn an example of , a UE (such as UE 115) may receive a downlink grant 705 including an indication that first channel state information 710 (such as aperiodic channel state information) is to be reported. The UE may also receive an uplink grant 715 including an indication that second channel state information 720 is to be reported. In some examples, the UE may receive the uplink grant 715 before receiving the downlink grant 705. In some examples, the UE may determine the transmission order based on a configuration received from a base station or a configuration otherwise identified by the UE. The configuration may indicate that out-of-sequence transmission is allowed between aperiodic channel state information triggered by a downlink grant (such as aperiodic channel state information 710 on a physical uplink control channel) and aperiodic channel state information triggered by an uplink grant (such as aperiodic channel state information 720 on a physical uplink control channel). In one example, the configuration may indicate that if the uplink grant 715 is received before the downlink grant 705, the periodic channel state information (such as the aperiodic channel state information 710) triggered by the downlink grant is allowed to be transmitted before the periodic channel state information (such as the aperiodic channel state information 720) triggered by the uplink grant. Additionally or alternatively, the configuration may indicate that if the downlink grant 705 is received after the uplink grant 715, the periodic channel state information (such as the aperiodic channel state information 710) triggered by the downlink grant is not allowed to be transmitted before the periodic channel state information (such as the aperiodic channel state information 720) triggered by the uplink grant. In some examples, the UE may receive the uplink grant 715 including an indication that the channel state information 720 is to be reported. In some cases, the uplink grant 715 may be received before the downlink grant 705. In such a case, the UE may transmit the aperiodic channel state information 710 before transmitting the aperiodic channel state information 720. Additionally or alternatively, the configuration may indicate that the channel state information 710 is allowed to be transmitted no earlier than the channel state information 720.
[0138] In some examples, the UE may determine that the channel state information 710 and the channel state information 720 are associated with the same channel state information reporting configuration (or the same channel state information resource configuration). In such examples, the UE may suppress transmitting the channel state information 720 based on determining that the channel state information 710 and the channel state information 720 are associated with the same channel state information reporting configuration. According to one or more aspects, the UE may determine that the configuration indicates that out-of-sequence transmission between downlink grant-triggered aperiodic channel state information (such as aperiodic channel state information 710 on a physical uplink control channel) and uplink grant-triggered aperiodic channel state information (such as aperiodic channel state information 720 on a physical uplink control channel) is allowed if a shorter timeline is used or defined for aperiodic channel state information reporting triggered by a downlink grant on a physical uplink shared channel than for an uplink grant-triggered aperiodic channel state information reporting. For example, the UE may determine that the timeline associated with the downlink grant 705 is less than the timeline associated with the uplink grant 715. In such a case, the UE may transmit the channel state message 710 prior to transmitting the channel state information 720 based on determining that the timeline associated with the downlink grant 705 is less than the timeline associated with the uplink grant 715 .
[0139] exist Figure 7B In an example of , a UE (such as UE 115) may receive a downlink grant 755 including an indication that first channel state information 760 (such as aperiodic channel state information) is to be reported. The UE may also receive an uplink grant 765 including an indication that second channel state information 770 is to be reported. In some examples, the UE may receive the uplink grant 765 after receiving the downlink grant 755. In some examples, the UE may determine the transmission order based on a configuration received from a base station or a configuration otherwise identified by the UE. The configuration may indicate that out-of-sequence transmission is not allowed between aperiodic channel state information triggered by an uplink grant (e.g., aperiodic channel state information 770) and aperiodic channel state information triggered by a downlink grant (e.g., aperiodic channel state information 760). For example, the configuration may indicate that the first channel state information 760 is not allowed to be transmitted earlier than the second channel state information 770.
[0140] Figure 8A block diagram 800 of a device 805 supporting transmission order determination for aperiodic channel state information according to aspects of the present disclosure is shown. The device 805 may be an example of aspects of a UE 115 as described herein. The device 805 may include a receiver 810, a communication manager 815, and a transmitter 820. The device 805 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).
[0141] The receiver 810 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to transmission order determination for non-periodic channel state information, etc.). The information may be passed to other components of the device 805. The receiver 810 may be a reference Fig.11 Examples of aspects of the described transceiver 1120. The receiver 810 may utilize a single antenna or a collection of antennas.
[0142] The communication manager 815 may receive a downlink grant including an indication that first channel state information is to be reported; receive a second grant including an indication that second channel state information is to be reported, wherein the second grant is received after the downlink grant, determine a transmission order associated with the first channel state information and the second channel state information based on a configuration; and transmit the first channel state information and the second channel state information according to the transmission order. The communication manager 815 may be an example of aspects of the communication manager 1110 described herein.
[0143] The communication manager 815 or its subcomponents may be implemented in hardware, software (e.g., executed by a processor), or any combination thereof. If implemented in code executed by a processor, the functions of the communication manager 815 or its subcomponents may be performed by a general purpose processor, DSP, application specific integrated circuit (ASIC), FPGA or other programmable logic device designed to perform the functions described in this disclosure, discrete gate or transistor logic, discrete hardware components, or any combination thereof.
[0144] The communication manager 815 or its subcomponents may be physically located at various locations, including being distributed such that portions of functionality are implemented by one or more physical components at different physical locations.
