[0001] This patent application claims the benefit of Greek Patent Application No. 20200100655 by Ozturk et al., entitled "ENHANCED DECODING FEEDBACK FOR TRAFFIC TYPE DIFFERENTIATION," filed October 29, 2020, which is assigned to the assignee of the present application and expressly incorporated herein by reference.

[0002] The following relates to wireless communications, including enhanced decoding feedback for traffic type differentiation. [Background technology]

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasts. These systems may be capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth-generation (4G) systems, such as Long Term Evolution (LTE), LTE-Advanced (LTE-A), or LTE-A Pro systems, and fifth-generation (5G) systems, sometimes referred to as new radio (NR) systems. These systems may 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 spread 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 simultaneously supporting communication for multiple communication devices, sometimes known as user equipment (UE).

[0004] A UE may receive and attempt to decode a packet received from another wireless device, such as a base station. Based on successful reception and decoding, the UE may send a positive acknowledgment (ACK) or negative acknowledgment (NACK) message to the base station. In some cases, the received packet may be a packet of a particular type of traffic, such as Ultra-Reliable Low-Latency Communications (URLLC), which may respond to a threshold level of error. Summary of the Invention

[0005] The described techniques relate to improved methods, systems, devices, and apparatuses that support enhanced decoding feedback for traffic type differentiation. Generally, the described techniques provide a user equipment (UE) that transmits enhanced feedback in addition to hybrid automatic repeat request (HARQ) feedback when a downlink message received from a base station is of a first traffic type, such as ultra-reliable low latency communication (URLLC). The UE may receive the downlink message from the base station. The UE may perform a decoding procedure for the received downlink message. The UE may determine a traffic type for the downlink message, where the traffic type is the first traffic type (e.g., URLLC) or a second traffic type (e.g., enhanced mobile broadband (eMBB), massive machine type communication (mMTC)). The UE may decide to send extended feedback along with an acknowledgment message (e.g., a positive acknowledgment message (ACK) or a negative acknowledgment message (NACK)) indicating a result of a decoding procedure for the received downlink message if the downlink message is of a first traffic type. The extended feedback may indicate channel quality information for the received downlink message. The UE may then send the ACK message and extended feedback for the ACK message along with the ACK message.

[0006] A method for wireless communication in a user equipment (UE) is described. The method may include receiving a downlink message from a base station, performing a decoding procedure for the received downlink message, determining that the downlink message has a traffic type associated with a quality of service level, determining based on the traffic type to transmit enhanced feedback along with an acknowledgement message indicating a result of the performed decoding procedure for the received downlink message, and transmitting the acknowledgement message and enhanced feedback for the acknowledgement message, the enhanced feedback indicating assistance information associated with the quality of service level for the received downlink message.

[0007] An apparatus for wireless communication in a UE is described. The apparatus may include a processor, a memory coupled to the processor, and instructions stored in the memory. The instructions may be executable by the processor to cause the apparatus to receive a downlink message from a base station, perform a decoding procedure for the received downlink message, determine that the downlink message has a traffic type associated with a quality of service level, determine based on the traffic type to send enhanced feedback along with an acknowledgement message indicating a result of the performed decoding procedure for the received downlink message, and send the acknowledgement message and enhanced feedback for the acknowledgement message, the enhanced feedback indicating assistance information associated with the quality of service level for the received downlink message.

[0008] Another apparatus for wireless communication in a UE is described, which may include means for receiving a downlink message from a base station, means for performing a decoding procedure for the received downlink message, means for determining that the downlink message has a traffic type associated with a quality of service level, means for determining, based on the traffic type, to transmit enhanced feedback along with an acknowledgement message indicating a result of the performed decoding procedure for the received downlink message, and means for transmitting the acknowledgement message and enhanced feedback for the acknowledgement message, the enhanced feedback indicating assistance information associated with the quality of service level for the received downlink message.

[0009] A non-transitory computer-readable medium storing code for wireless communication in a UE is described. The code may include instructions executable by a processor to receive a downlink message from a base station, perform a decoding procedure for the received downlink message, determine that the downlink message has a traffic type associated with a quality of service level, determine based on the traffic type to transmit enhanced feedback along with an acknowledgement message indicating a result of the performed decoding procedure for the received downlink message, and transmit the acknowledgement message and enhanced feedback for the acknowledgement message, the enhanced feedback indicating assistance information associated with the quality of service level for the received downlink message.

DETAILED DESCRIPTION OF THE INVENTION

[0058]

[0067] A user equipment (UE) may communicate with other wireless devices, such as base stations, in a wireless communication system. The UE and base station may transmit and receive messages to communicate. The base station may transmit a downlink message to the UE, and the UE may attempt to receive and decode the downlink message. Based on whether the UE successfully receives and decodes the message, the UE may transmit feedback to the base station. The feedback may be an example of hybrid automatic repeat request (HARQ) feedback. In the event of successful reception and decoding of a message, the UE may transmit a positive acknowledgement message (ACK) to the base station for the received message. In some cases, the UE may not successfully receive and decode a message, and as a result, the UE may transmit a negative acknowledgement message (NACK) to the base station. If the base station transmitting the message receives a NACK, the device may retransmit the message to the UE. In some situations, such as in the case of ultra-reliable low latency communication (URLLC), it may be beneficial for the UE to include additional information with the acknowledgement message, such as an expected error rate.

[0059]

[0068] The UE may be configured to communicate using different traffic types (e.g., different quality of service (QoS) levels) for different data messages, such as URLLC, enhanced mobile broadband (eMBB), or massive machine-type communications (mMTC). Extended feedback (e.g., information regarding error rate or channel quality) may be used for URLLC data messages (e.g., high-priority communications). In some cases, extended feedback may not be used for some types of traffic, such as eMBB or mMTC (e.g., low-priority communications). Thus, the UE may determine the type of traffic received in a data message from the base station, and the UE may determine whether to send extended feedback. The UE may determine how to send extended feedback (e.g., what to send in feedback and how frequently to send feedback) based on the determined type of traffic.

[0060]

[0069] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are then described in the context of a process flow. Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts relating to enhanced decoding feedback for traffic type differentiation.

[0061]

[0070] 1 illustrates an example of a wireless communication system 100 supporting enhanced decoding feedback for traffic type differentiation in accordance with an aspect of the present disclosure. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low-latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0062]

[0071] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may be devices of different forms or with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base stations 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 may support communication of signals according to one or more radio access technologies.

[0063]

[0072] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be fixed, mobile, or both at different times. The UEs 115 may be devices of different forms or with different capabilities. Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein may be configured to communicate with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment), as shown in FIG. 1.

[0064]

[0073] The base stations 105 may communicate with the core network 130, with each other, or both. For example, the base stations 105 may interface with the core network 130 through one or more backhaul links 120 (e.g., via an S1, N2, N3, or other interface). The base stations 105 may communicate with each other over the backhaul links 120 (e.g., via an X2, Xn, or other interface) either directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130), or both. In some examples, the backhaul links 120 may be or include one or more wireless links.

[0065]

[0074] One or more of the base stations 105 described herein may include or be referred to by those skilled in the art as a base transceiver station, radio base station, access point, radio transceiver, Node B, eNode B (eNB), Next Generation Node B or GigaNode B (any of which may be referred to as gNB), Home Node B, Home eNode B, or other suitable terminology.

[0066]

[0075] The UE 115 may include or be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where a “device” may be referred to as a unit, a station, a terminal, or a client, among other examples. The UE 115 may include or be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, the UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine-type communication (MTC) device, among other examples, which may be implemented in various objects, such as an appliance, a vehicle, a meter, or the like, among other examples.

[0067]

[0076] The UEs 115 described herein may be configured to communicate with various types of devices, such as other UEs 115, which may act as relays at times, as shown in FIG. 1, as well as base stations 105 and network equipment, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples.

[0068]

[0077] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier used for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling that coordinates the operation of the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0069]

[0078] In some examples (e.g., in a carrier aggregation configuration), a carrier may have acquisition or control signaling that coordinates operation for other carriers. Carriers may be associated with frequency channels (e.g., Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Numbers (EARFCNs)) and may be arranged according to a channel raster for discovery by UE 115. Carriers may be operated in a standalone mode, where initial acquisition and connection may be made by UE 115 via the carrier, or the carrier may be operated in a non-standalone mode, where a connection is established using a different carrier (e.g., of the same or different radio access technology).

[0070]

[0079] The communication links 125 shown in the wireless communication system 100 may include uplink transmissions from the UE 115 to the base station 105 or downlink transmissions from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in FDD mode) or may be configured to carry downlink and uplink communications (e.g., in TDD mode).

[0071]

[0080] A carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the 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)) for a carrier of a particular radio access technology. The devices of the wireless communication system 100 (e.g., the base station 105, the UE 115, or both) may have a hardware configuration that supports communication over a particular carrier bandwidth or may be configurable to support communication over one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or a UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate over a portion (e.g., a sub-band, BWP) or all of the carrier bandwidth.

[0072]

[0081] A signal waveform transmitted on a carrier may be composed of multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may include one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and the subcarrier spacing have an inverse relationship. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Thus, the more resource elements and the higher the order of the modulation scheme received by the UE 115, the higher the data rate for the UE 115 may be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communications with the UE 115.

[0073]

[0082] One or more numerologies may be supported for a carrier, where the numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. 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 communication for the UE 115 may be limited to one or more active BWPs.

[0074]

[0083] The time interval for the base station 105 or the UE 115 may be, for example, T s =1 / (Δf max N f ) seconds, where Δf max may represent the maximum supported subcarrier spacing, and N fmay represent the maximum supported discrete Fourier transform (DFT) size. The communication resource time intervals 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).

[0075]

[0084] Each frame may include multiple consecutively numbered subframes or slots, and each subframe or 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 several slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on the subcarrier spacing. Each slot may include several symbol periods (e.g., depending on the length of a cyclic prefix prepended to each symbol period). In some wireless communications systems 100, a slot may be further divided into multiple minislots containing one or more symbols. Excluding the cyclic prefix, each symbol period may include one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the frequency operating band.

[0076]

[0085] A subframe, slot, minislot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0077]

[0086] Physical channels may be multiplexed on carriers according to various techniques. Physical control channels and physical data channels may be multiplexed on downlink carriers using, for example, 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 several symbol periods and may span the system bandwidth of the carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESET) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may monitor or search the 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 at one or more aggregation levels configured in a cascaded manner. The aggregation level for the control channel candidates may refer to several 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 sending control information to multiple UEs 115 and a UE-specific search space set for sending control information to a specific UE 115.

[0078]

[0087] Each base station 105 may provide communication coverage via one or more cells, e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with the base station 105 (e.g., on a carrier) and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) to distinguish neighboring cells. In some examples, a cell may refer to a geographic coverage area 110 or a portion (e.g., a sector) of a geographic coverage area 110 in which the logical communication entity operates. Such a cell may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area, depending on various factors such as the capabilities of the base station 105. For example, a cell may be or include a building, a subset of a building, or an outer space between or overlapping with the geographic coverage area 110, among other examples.

[0079]

[0088] A macro cell generally covers a relatively large geographic area (e.g., a few kilometers in radius) and may allow unrestricted access by UEs 115 with a service subscription with the network provider that supports the macro cell. Small cells may be associated with lower-power base stations 105 compared to macro cells, and the small cells may operate in the same or different (e.g., licensed, unlicensed) frequency bands as the macro cell. A small cell may provide unrestricted access to UEs 115 with a service subscription with the network provider, or may provide restricted access to UEs 115 that have an association with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users at home or in the office). A base station 105 may support one or more cells and may support communication on one or more cells using one or more component carriers.

[0080]

[0089] 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.

[0081]

[0090] In some examples, the base stations 105 are mobile and may therefore provide communication coverage to moving 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 a heterogeneous network in which different types of base stations 105 provide coverage to various geographic coverage areas 110, for example, using the same or different radio access technologies.

[0082]

[0091] The wireless communications 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, in some examples, not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operation.

[0083]

[0092] 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 technologies that enable devices to communicate with each other or with the base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices that incorporate sensors or meters to measure or capture information and relay such information to a central server or application program that utilizes the information or presents the information to a human interacting with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security detection, physical access control, and transaction-based business billing.

[0084]

[0093] Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception rather than simultaneous transmission and reception). In some examples, half-duplex communication may be implemented at a reduced peak rate. Other power-saving techniques for UEs 115 include entering a power-saving deep sleep mode when not engaged in active communication, operating on a limited bandwidth (e.g., pursuant to narrowband communication), or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of the carrier, or outside of the carrier.

[0085]

[0094] The wireless communication system 100 may be configured to support ultra-reliable or low-latency communications, or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communications (URLLC) or mission-critical communications. The UE 115 may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission-critical functions). Ultra-reliable communications may include private or group communications and may be supported by one or more mission-critical services, such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions may include service prioritization, and the mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency may be used interchangeably herein.

[0086]

[0095] In some examples, the UEs 115 may be configured to communicate directly with other UEs 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 the geographic coverage area 110 of the 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 configured or positioned to receive transmissions from the base station 105. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, the base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication occurs between UEs 115 without the involvement of the base station 105.

[0087]

[0096] In some systems, the D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-anything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination thereof. Vehicles may signal information regarding traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or a network via one or more network nodes (e.g., base stations 105) using vehicle-to-network (V2N) communication, or both.

[0088]

[0097] 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 5G core (5GC) that may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) that routes packets or interconnections to external networks. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management, for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be forwarded through the user plane entity, which may provide IP address allocation and other functions. The user plane entities may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, intranet(s), IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0089]

[0098] Some of the network devices, such as the base station 105, may include sub-components, such as an access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with the UE 115 through one or more other access network transmitting entities 145, which may be referred to as a radio head, a smart radio head, or a transmit / receive point (TRP). Each access network transmitting entity 145 may include one or more antenna panels. In some configurations, 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 integrated into a single network device (e.g., the base station 105).

[0090]

[0099] The wireless communication system 100 may operate using one or more frequency bands (e.g., in the range of 300 megahertz (MHz) to 300 gigahertz (GHz)). Generally, the 300 MHz to 3 GHz region is known as the ultra-high frequency (UHF) region or decimeter band because wavelengths range from approximately 1 decimeter to 1 meter in length. Although UHF waves may be blocked or redirected by buildings and environmental features, the waves may penetrate structures sufficiently for a macrocell to provide service to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmissions using the smaller frequencies and longer waves in the short wave (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0091]

[0100] The wireless communication system 100 may operate in the very high frequency (SHF) region, using the frequency band from 3 GHz to 30 GHz, also known as the centimeter band, or the extremely high frequency (EHF) region of the spectrum, also known as the millimeter band (e.g., from 30 GHz to 300 GHz). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the base station 105, and the EHF antennas on each device may be smaller and more closely spaced than UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, propagation of EHF transmissions may experience greater atmospheric attenuation and shorter distances than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the designated use of bands across these frequency regions may vary by country or regulatory body.

[0092]

[0101] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ license-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 the base station 105 and the UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation in an unlicensed band may be based on a carrier aggregation configuration with component carriers operating in a licensed band (e.g., LAA). Operation in an unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0093]

[0102] The base station 105 or the UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or the UE 115 may be located in one or more antenna arrays or antenna panels that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located in an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with the base station 105 may be located in various geographic locations. The base station 105 may have an antenna array with several rows and columns of antenna ports that the base station 105 can use to support beamforming of 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 through the antenna ports.

[0094]

[0103] A base station 105 or a UE 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques are sometimes referred to as spatial multiplexing. Multiple signals may be transmitted by a transmitting device via different antennas or different combinations of antennas, for example. Similarly, multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits related to 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 used for channel measurement and reporting. MIMO techniques include 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.

[0095]

[0104] Beamforming, sometimes referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting and receiving devices. Beamforming may be achieved by combining signals communicated via antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array experience constructive interference and others experience destructive interference. Adjustment of signals communicated via antenna elements may include the transmitting or receiving device applying an amplitude offset, a phase offset, or both to signals carried via the antenna element associated with the device. The adjustment associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., relative to the antenna array of the transmitting or receiving device, or to some other orientation).

[0096]

[0105] 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 a beamforming operation 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 beamforming weight sets associated with different transmission directions. The transmissions in different beam directions may be used to identify beam directions (e.g., by a transmitting device such as the base station 105 or by a receiving device such as the UE 115) for subsequent transmission or reception by the base station 105.

[0097]

[0106] Some signals, such as data signals associated with a particular receiving device, may be transmitted by the base station 105 in a single beam direction (e.g., a direction associated with the receiving device, such as the UE 115). In some examples, the beam direction associated with a transmission along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, the UE 115 may receive one or more of the signals transmitted by the base station 105 in different directions and may report to the base station 105 an indication of the signal that the UE 115 received with the best or otherwise acceptable signal quality.

[0098]

[0107] In some examples, transmission by a device (e.g., by the base station 105 or the UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a composite 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, where 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 (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may be precoded or ampliconed. 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 have been described with respect to signals transmitted in one or more directions by the base station 105, the UE 115 may employ similar techniques to transmit a signal multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by the UE 115) or to transmit a signal in a single direction (e.g., to transmit data to a receiving device).

[0099]

[0108] A receiving device (e.g., UE 115) may attempt multiple receive configurations (e.g., directional listening) when receiving various signals from the base station 105, such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, the receiving device may attempt multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of the antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of the antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, the receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receiving configuration may be aligned in a beam direction determined based on listening along different receiving configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening along multiple beam directions).

[0100]

[0109] The wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communications at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. The Radio Link Control (RLC) layer may perform packet segmentation and reassembly for communications on logical channels. The Medium Access Control (MAC) layer may perform priority handling and multiplexing of logical channels onto transport channels. The MAC layer may use error detection, error correction, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer may provide establishment, configuration, and maintenance of an RRC connection between the UE 115 and the base station 105 or core network 130, supporting radio bearers for user plane data. In the physical layer, transport channels may be mapped to physical channels.

[0101]

[0110] The UE 115 and the 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 one technique for increasing the likelihood that data is accurately received over the communication link 125. HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device may support same-slot HARQ feedback, where the device may provide HARQ feedback in a particular slot for data received in a previous symbol in that slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0102]

[0111] The UE 115 may receive a downlink message from the base station 105. The UE 115 may perform a decoding procedure for the received downlink message. The UE 115 may determine a traffic type for the downlink message, the traffic type being a first traffic type or a second traffic type, where the first traffic type is associated with a lower error rate, lower latency, or both, than the second traffic type. The UE 115 may determine to send extended feedback along with an acknowledgement message (e.g., an ACK or NACK) indicating a result of the decoding procedure for the received downlink message if the downlink message is of the first traffic type. The extended feedback may indicate assistance information related to a quality of service level, e.g., channel quality information or an estimated error rate, for the received downlink message. The UE 115 may then send the acknowledgement message and extended feedback about the acknowledgement message together with the acknowledgement message to the base station 105.

[0103]

[0112] FIG. 2 illustrates an example of a wireless communication system 200 supporting enhanced decoding feedback for traffic type differentiation according to aspects of the present disclosure. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. The UE 115-a may be an example of the UE 115 described with reference to FIG. 1. The base station 105-a may be an example of the base station 105 described with reference to FIG. 1. The base station 105-a may serve the UEs 115, including the UE 115-a, within its coverage area 110-a. The base station 105-a may transmit messages to the UE 115-a over communication link 125-a. The UE 115-a may receive messages from the base station 105-a. The UE 115-a may communicate with the base station 105-a by transmitting messages over communication link 125-b. The base station 105-a may receive these messages.

[0104]

[0113] The base station 105-a may transmit one or more downlink messages 205 to the UE 115-a over the communication link 125-a. The downlink messages 205 may be of a particular traffic type. The base station 105-a may transmit downlink messages 205 that are traffic types corresponding to an ultra-reliable communication QoS level, a low-latency QoS level, a URLLC communication level, or another type of high QoS, low error rate, or low delay or latency communication traffic type, or a combination thereof.

[0105]

[0114] The UE 115-a may receive the downlink message 205 and attempt to decode the downlink message 205. The UE 115-a may identify whether the UE 115-a successfully received and decoded the downlink message 205. The UE 115-a may determine to send a feedback message, such as an acknowledgement message 215, based on whether the downlink message 205 was successfully received and decoded. The acknowledgement message 215 may indicate whether the UE 115 successfully received and decoded the downlink transmission. The acknowledgement message 215 may be in the form of a HARQ ACK / NACK feedback bit. The ACK feedback bit may indicate that the UE 115-a successfully received and decoded the data in the downlink message 205. The NACK feedback bit may indicate that the UE 115-a did not successfully receive or decode the data in the downlink transmission. In some cases, the HARQ ACK / NACK feedback occasions may be semi-statically configured, and in other cases, the HARQ ACK / NACK feedback occasions may be dynamically configured.

[0106]

[0115] In some examples, the UE 115-a may determine a traffic type of the downlink message 205. The traffic type may correspond to a QoS level of the downlink message 205. The UE 115-a may determine whether the downlink message 205 is of a first traffic type or a second traffic type. The first traffic type may include an ultra-reliable communication type, a low-latency communication type, or other communication type that may rely on a low error rate or small delay. The second communication type may include a communication type such as eMBB or other communication type that does not support low-latency or ultra-reliable communication. In some cases, the UE 115-a may determine whether to send enhanced feedback based on the determined traffic type. In some cases, the UE 115-a may determine how to send feedback (e.g., what to send in feedback, whether to send enhanced feedback, how frequently to send feedback, etc.) based on the determined type of traffic. Additionally or alternatively, different types of feedback for different types of traffic may vary. For example, the extended feedback may include a first type of feedback information for a high-priority communication (e.g., ultra-reliable communication, URLCC) and a second type of feedback information for a low-priority communication (e.g., eMBB, mMTC). In some cases, the UE 115-a may transmit the extended feedback according to a first periodicity (e.g., relatively high periodicity) of transmissions for the high-priority communication (e.g., URLCC) and a second periodicity (e.g., relatively low periodicity) of transmissions for the low-priority communication (e.g., eMBB, mMTC). In some cases, the UE 115-a may send feedback more frequently for the first traffic type than for the second traffic type (e.g., may report feedback every 10 ms for the first traffic type and every 100 ms for the second traffic type).

[0107]

[0116] The UE 115-a may determine that the downlink message 205 is of a first traffic type. In these cases, the UE 115-a may decide to provide enhanced feedback 210 in addition to the acknowledgement message 215. The enhanced feedback may include an expected error rate associated with the downlink message 205, or channel quality information associated with the downlink message 205, or another type of additional feedback information.

[0108]

[0117] The UE 115-a may transmit the enhanced feedback 210 in a Layer 1 transmission (e.g., a physical layer including a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH)) or a Layer 2 transmission (e.g., a MAC layer). The UE 115-a may transmit the enhanced feedback 210 in a Layer 1 transmission if the acknowledgement message 215 is a NACK. The UE 115-a may transmit the enhanced feedback 210 in a Layer 2 transmission if the acknowledgement message 215 is a positive ACK. In some cases, the enhanced feedback 210 may indicate a requirement for a lower error rate or lower latency, or both, than the operating conditions under which the downlink message 205 is transmitted.

[0109]

[0118] The UE 115-a may transmit the enhanced feedback 210 periodically or after each transmission. For example, the UE 115-a may identify periodic scheduled or permitted uplink occasions for transmitting the enhanced feedback. The UE 115-a may send the enhanced feedback 210 in an uplink occasion following the downlink occasion in which the downlink message 205 was received by the UE 115-a.

[0110]

[0119] In some cases, the UE 115-a may decide to send the enhanced feedback 210 according to a trigger. The trigger may be that an estimated error rate of the downlink message 205 is higher than a threshold or target error rate. If the estimated error rate is above the threshold, the UE 115-a may decide to send the enhanced feedback 210 for that downlink message 205. In some cases, the UE 115-a may receive a request from the base station 105-a to send the enhanced feedback 210.

[0111]

[0120] In some cases, the base station 105-a may transmit an indication of the QoS (e.g., traffic type) of the downlink message 205 in a Layer 1 transmission. This Layer 1 transmission may be a downlink control information (DCI) message. The QoS level may be in the form of a priority value, which may depend on the multiplexed data radio bearer (DRB) payload in the scheduled downlink message 205. The UE 115-a may determine the traffic type of the downlink message 205 based on the received indication.

[0112]

[0121] Additionally or alternatively, the UE 115-a may determine the QoS and corresponding traffic type of the downlink message 205 based on a set of logical channels multiplexed in a MAC transport block on which the UE 115-a received the downlink message 205. For example, the UE 115-a may determine the traffic type based on the traffic type corresponding to the logical channel with the highest channel quality index (CQI) (e.g., 5G CQI) multiplexed in the corresponding DRB.

[0113]

[0122] The UE 115-a may send enhanced feedback 210 and an acknowledgment message 215. The enhanced feedback 210 may be based on the downlink message 205 having a QoS level corresponding to a first traffic type. In some cases, the UE 115-a may receive multiple downlink messages 205 during a time period. The UE 115-a may determine to send enhanced feedback 210 for (e.g., for only) the downlink message 205 corresponding to a first traffic type (e.g., the highest QoS level) among the set of downlink messages 205 received during the time period. In other cases, the UE 115-a may send enhanced feedback 210 for multiple different QoS levels of the downlink message 205. For example, the UE 115-a may transmit enhanced feedback 210 including a first value for a downlink message 205 of a first QoS level, and the UE 115-a may transmit enhanced feedback 210 including a second value for a downlink message 205 of a second QoS level (e.g., lower than the first QoS level).

[0114]

[0123] Furthermore, the UE 115-a may determine the enhanced feedback 210 and the associated QoS level according to the physical resource on which the enhanced feedback 210 is sent. For example, the UE 115-a may receive the downlink message 205, and the UE 115-a may identify a resource for transmitting feedback about the downlink message 205. The UE 115-a may identify the enhanced feedback 210 corresponding to the downlink message 205 or the QoS level of the downlink message 205 based on the resource on which the UE 115-a will transmit the enhanced feedback 210, rather than the resource on which the UE 115-a received the downlink message 205. The enhanced feedback 210 may include a specific criterion for the QoS level. This specific criterion may be based on the priority level of the downlink message 205 (e.g., as received in the DCI) or may include a logical channel identifier, a QoS flow identifier, or a CQI identifier (e.g., a 5G CQI identifier) ​​as an indicator of the QoS level in the MAC control element (MAC-CE) enhanced feedback 210 transmission.

[0115]

[0124] In other cases, the UE 115-a may determine that the downlink message 205 is of a second traffic type that is different from the first traffic type. In these cases, the UE 115-a may decide not to send the enhanced feedback 210 or may decide to send a different type of enhanced feedback.

[0116]

[0125] 3 illustrates an example of a process flow 300 supporting enhanced decoding feedback for traffic type differentiation according to aspects of the present disclosure. In some examples, the process flow 300 may implement aspects of the wireless communication systems 100 and 200. The process flow 300 includes a UE 115-b, which may be an example of the UE 115 described with reference to FIGS. 1 and 2. The process flow 300 also includes a base station 105-b, which may be an example of the base station 105 described with reference to FIGS. 1 and 2. The UE 115-b and the base station 105-b may communicate as part of the wireless communication system.

[0117]

[0126] At 305, the base station 105-b may determine a traffic type for a downlink message to be transmitted to the UE 115-b. The traffic type may be a first traffic type or a second traffic type. The first traffic type may be associated with a lower error rate, lower latency, or both, than the second traffic type. For example, the first traffic type may be a URLLC type.

[0118]

[0127] At 310, the base station 105-b may transmit a downlink message to the UE 115-b. The UE 115-b may receive the downlink message from the base station 105-b.

[0119]

[0128] At 315, the UE 115-b may perform a decoding procedure for the received downlink message. At 320, the UE 115-b may determine a traffic type for the downlink message, where the traffic type is a first traffic type or a second traffic type. The first traffic type may be associated with a lower error rate, lower latency, or both, than the second traffic type. The first traffic type may be different from the second traffic type, and the second traffic type may be associated with a type of enhanced feedback that is different from the enhanced feedback associated with the acknowledgment message.

[0120]

[0129] In some cases, the UE 115-b may receive a DCI message from the base station 105-b. In these cases, the UE 115-b may determine the first traffic type based on the QoS level indicated by the DCI message. The enhanced feedback transmitted at 335 may include an indication of the QoS indicated by the DCI message. Furthermore, the UE 115-b may determine, for each logical channel of the set of logical channels multiplexed in the downlink message, a QoS level for the logical channel. The UE 115-b may determine the first traffic type based on the highest QoS level among the determined QoS levels.

[0121]

[0130] At 325, UE 115-b may determine, based on the received downlink message being of the first traffic type, to transmit enhanced feedback along with an acknowledgement message indicating a result of a performed decoding procedure for the received downlink message. The enhanced feedback may indicate assistance information related to a quality of service level, such as channel quality information or an expected error rate, for the received downlink message.

[0122]

[0131] In some cases, the UE 115-b may determine that a trigger condition is satisfied, and the UE 115-b may transmit enhanced feedback based on determining that the trigger condition is satisfied. In some cases, the UE 115-b may determine that an error rate threshold for the first traffic type is satisfied, where the trigger condition includes determining that the error rate threshold is satisfied. In some cases, the UE 115-b may transmit enhanced feedback based on determining that the error rate threshold is satisfied, and the error rate threshold may indicate a downlink message with a minimum error rate.

[0123]

[0132] At 330, the UE 115-b may transmit an acknowledgment message. At 335, the UE 115-b may transmit extended feedback for the acknowledgment message. The extended feedback may include an indication of the first traffic type. The indication may include a logical channel identifier, a QoS flow identifier (e.g., a 5G QoS identifier), or a combination thereof. The UE 115-b may transmit extended feedback for the acknowledgment message along with the acknowledgment message. Based on a result of the decoding procedure, the UE 115-b may determine whether to transmit extended feedback in a first layer transmission or a second layer transmission. In some cases, the UE 115-b may transmit extended feedback in a first layer based on the acknowledgment message being a NACK message. In other cases, the UE 115-b may transmit extended feedback in a second layer based on the acknowledgment message being a positive ACK message. The first layer may be a physical layer, and the second layer may be a MAC layer.

[0124]

[0133] In some cases, the UE 115-b may periodically transmit enhanced feedback indicating assistance information related to the quality of service level for downlink messages of the first traffic type. The UE 115-a may transmit enhanced feedback associated with the downlink message for each downlink message received from the base station 105-b.

[0125]

[0134] UE 115-b may identify a first set of resources for enhanced feedback of the first traffic type and a second set of resources for feedback messages of the second traffic type. UE 115-b may then transmit the enhanced feedback on the first set of resources.
