Abstract

Methods, systems, and devices for wireless communication are described. A wireless device, such as a user equipment (UE), can receive a message indicating a coding procedure, such as a multi-level coding (MLC) procedure, implemented for ongoing communications. The UE can select, from the plurality of code rate indicator values, a first code rate indicator value corresponding to a first code rate for a first coding level of the coding procedure, and can select a second code rate indicator value corresponding to a second code rate for a second coding level of the coding procedure. The UE can then send a coding level indicator report comprising the selected first code rate indicator value and the selected second code rate indicator value. Based on the transmitted coding level indicator report, the UE can communicate at least one data packet using a coding procedure and a first code rate and a second code rate.

[0002] This patent application claims the benefit of U.S. patent application No. 17 / 857,734, entitled “DYNAMIC REPORTING OF MULTI-LEVEL CODING CONFIGURATIONS,” filed by Landis et al. on July 5, 2022, which is assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field

[0003] The following relates to wireless communications, including dynamic reporting of multi-level coding (MLC) configurations. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (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, each of which supports wireless communications for communication devices, which may be referred to as user equipment (UE). Summary of the invention

[0005] The described techniques relate to improved methods, systems, devices, and apparatuses that support dynamic reporting of multi-level coding (MLC) configurations. For example, the described techniques provide support for a variety of different modulation and coding procedures that provide different levels of error protection for coded transmissions. To reduce power consumption, a device may perform different types of coding procedures, such as MLC, where encoding and decoding may be split into multiple levels such that different component codes (e.g., code rate, modulation order, or both) are applied to non-overlapping sets of bits. To perform MLC, a wireless device may select a code rate indicator value, such as a channel quality indicator (CQI) index corresponding to the modulation order and coding scheme, for each code level.

[0006] To more efficiently report CQI to select modulation order and coding rate values ​​for MLC, the wireless device may select and report one CQI value per code level of the MLC procedure. For example, for a first coding level, the wireless device may select a first CQI index associated with a first modulation order and a first coding rate from a first CQI table. For a second coding level, the wireless device may select a second CQI index associated with a second coding rate from a second CQI table. The wireless device may report the selected CQI index in a coding level indicator report and may receive subsequent control signaling from the network indicating which CQI indexes were selected and which corresponding modulation and coding scheme (MCS) values ​​to use for each level of MLC.

[0045] A wireless device such as a user equipment (UE) may support a variety of different modulation and coding procedures to generate one or more data symbols for transmission from a set of information bits. Available decoding procedures associated with a set of available modulation and coding procedures may provide different levels of error protection for each bit (e.g., a binary bit) representing a data symbol generated according to a symbol constellation. The UE may implement various types of decoding procedures such as low-density parity check (LDPC) decoding to perform channel coding and decoding. However, in some cases, these types of channel decoding procedures utilize expensive power resources (e.g., may consume power above a threshold power level), which may reduce battery life.

[0046] To reduce power consumption, the device may perform different kinds of decoding procedures such as multi-level coding (MLC) procedures. In MLC, encoding and decoding may be split into multiple levels so that different component codes (e.g., code rates or modulation orders) are applied to sets of bits (e.g., non-overlapping sets of bits). To perform multiple levels of decoding, the UE may select a channel quality indicator (CQI) index corresponding to the modulation order and coding scheme for each code level. Since MLC constitutes at least two code levels, the number of possible MCS combinations is wide (e.g., may exceed a threshold) because the selected CQI index corresponds to the modulation order and coding scheme for each code level used for MLC.

[0047] In some examples, to more efficiently report CQI to select a modulation order and coding rate value for MLC, the UE may select and report one CQI value per code level of the MLC procedure (e.g., rather than transmitting a single CQI value to select both the modulation order and the coding rate value). For example, for a first coding level, the UE may select a first CQI index associated with a first modulation order and a first coding rate from a first CQI table, and then for a second coding level, the UE may select a second CQI index associated with a second coding rate from a second CQI table. The UE may transmit the selected index to the network in a UE report such as a channel state information (CSI) report, and may receive subsequent control signaling from the network indicating which CQI indexes are selected and which corresponding modulation and coding scheme (MCS) values ​​are to be used for each level of MLC. By selecting CQI values ​​separately for each code level, the UE may effectively be able to improve spectral efficiency and reduce power consumption associated with the MLC procedure.

[0048] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated and described by and with reference to process flows, apparatus diagrams, system diagrams, and flow diagrams related to dynamic reporting of MLC configurations.

[0049] Figure 1An example of a wireless communication system 100 supporting dynamic reporting of MLC configuration according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 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, a New Radio (NR) network, or a network operating according to other systems and radio technologies including future systems and radio technologies not explicitly mentioned herein.

[0050] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other nomenclature. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0051] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communication with, for example, Figure 1 Communications with various types of devices of other UEs 115 or network entities 105 are shown.

[0052] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.

[0053] In some examples, the network entities 105 may communicate with the core network 130, or communicate with each other, or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3 or other interface protocols). In some examples, the network entities 105 may communicate with each other via the backhaul communication link 120 (e.g., according to X2, Xn or other interface protocols) directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130). In some examples, the network entities 105 may communicate with each other via the midhaul communication link 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication link 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, the midhaul communication link 162, or the fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0054] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a home Node B, a home evolved Node B, or other suitable terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, stand-alone) base station architecture, which may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0055] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0056] The functional split between CU 160, DU 165, and RU 170 is flexible and may support different functionalities, depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DU 165 and the RU 170, such that the DU 165 may support one or more layers of the protocol stack, and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 can be within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by different ones of CU 160, DU 165, or RU 170). CU 160 can be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 can be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that communicate via such communication links.

[0057] In some wireless communication systems (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DUs 165 or one or more RUs 170 may be controlled in part by one or more CUs 160 associated with a donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a coupled IAB donor's DU 165. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0058] In the case where the techniques described herein are applied to the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support dynamic reporting of MLC configurations as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0059] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0060] The UE 115 described herein may be capable of communicating with various types of devices such as other UEs 115 which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0061] The UE 115 and the network entity 105 may use resources associated with one or more carriers to wirelessly communicate with each other via one or more communication links 125 (e.g., access links). The term "carrier" may refer to a collection of RF spectrum resources having a physical layer structure defined to support the communication link 125. For example, a carrier for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between these devices and any portion (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send," "receive," or "communicate" when referring to the network entity 105 may refer to any portion of a network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0062] The signal waveform transmitted via 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 refer to a symbol period (e.g., the duration of a modulation symbol) and a resource of a subcarrier, in which case the symbol period and the subcarrier spacing may be 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 coding rate of the modulation scheme, or both), so that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high order modulation scheme may correspond to a relatively high rate of communication. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0063] The time interval for the network entity 105 or the UE 115 may be expressed as a multiple of a basic time unit, which may be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, where Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. The time intervals of the communication resources may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0064] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain 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 certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of micro time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0065] 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 transmit time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0066] Carriers may be used to multiplex physical channels for communication according to various techniques. Physical control channels and physical data channels may be multiplexed, 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 to signal via a downlink carrier. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth of a carrier or a subset of that system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE 115 may monitor or search a control region to obtain control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the amount 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 .

[0067] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0068] 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). UE 115 may be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communication may include private communication or group communication, and may be supported by one or more services (such as push-to-talk, video, or data). Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.

[0069] In some examples, a UE 115 may be configured to support communication directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group that are performing D2D communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 of such a group may be outside of the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.

[0070] 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), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or 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 network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP service 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0071] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength ranges from about one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves may be sufficient to penetrate structures so that macro cells provide services to UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to communications using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0072] The wireless communication system 100 may also operate using a super high frequency (SHF) region that may be in the range of 3 GHz to 30 GHz (also referred to as a centimeter band) or an extremely high frequency (EHF) region that uses a spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as a millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between a UE 115 and a network entity 105 (e.g., a base station 140, a RU 170), and the EHF antenna of the corresponding device may be smaller and closer than the UHF antenna. In some examples, such technology may be facilitated using an antenna array within the device. However, the propagation of EHF transmissions may be subject to even greater 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 regions, and the use of frequency bands specified across these frequency regions may differ by country or regulatory agency.

[0073] The wireless communication system 100 can utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can utilize licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology using unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating using unlicensed RF spectrum bands, devices such as network entity 105 and UE 115 can use carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands can be based on a carrier aggregation configuration combined with component carriers operating using licensed bands (e.g., LAA). Operations using unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and the like.

[0074] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0075] 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 network entity 105, a UE 115) to shape or direct 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 conveyed via antenna elements of an antenna array so that some signals propagating along a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed via antenna elements may include a transmitting device or a receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0076] The wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication at the bearer or PDCP layer can be IP-based. The RLC layer can perform packet segmentation and reassembly to communicate via logical channels. The MAC layer can perform priority processing and multiplexing of logical channels into transport channels. The MAC layer can also use error detection technology, error correction technology, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer can provide the establishment, configuration, and maintenance of the RRC connection that supports the radio bearer of user plane data between the UE115 and the network entity 105 or the core network 130. The PHY layer can map the transport channel to the physical channel.

[0077] The wireless communication system 100 may support procedures for estimating characteristics of a channel. In some examples, reference signals are communicated between wireless devices and used to determine characteristics of a channel between the wireless devices (e.g., timing, frequency, or attenuation characteristics). Reference signals may include channel state information (CSI) reference signals (RS) (CSI-RS), demodulation reference signals (DMRS), sounding reference signals (SRS), tracking reference signals (TRS), phase tracking reference signals (PTRS), etc. A wireless device (e.g., UE) may receive a reference signal from another wireless device (e.g., a network entity) and use a received version of the reference signal and a transmitted version of the reference signal (which may be known to the wireless device) to determine characteristics of the channel over which the reference signal is transmitted (e.g., signal quality, Doppler frequency, power delay profile, delay spread, etc.). The wireless device may use the estimated channel to determine transmission parameters (e.g., preferred precoding matrix and rank) that are well suited for the channel.

[0078] The wireless device may use the estimated channel to determine additional transmit parameters (e.g., a preferred MCS) based on the other transmit parameters. In some examples, the wireless device uses the estimated channel and (in some examples) one or more determined transmit parameters to determine a spectral efficiency achievable for the channel (e.g., a throughput that can be delivered over the link using the allocated resources). In some examples, the preferred MCS may be determined based on the determined spectral efficiency.

[0079] After determining the preferred transmission parameters for the estimated channel, the wireless device may send an indication of the preferred transmission parameters to another wireless device. In some examples, the wireless device may generate a report including an indication of the preferred transmission parameters, which may be referred to as a channel state feedback (CSF) report. The CSF report may include CQI, precoding matrix indicator (PMI), rank indicator (RI), beam indicator (CRI), etc. The value of the CQI may be based on the spectral efficiency available for the channel. In some examples, the value of the CQI is selected using a table that maps CQI indexes to spectral efficiency values ​​and MCS. For example, for a first calculated spectral efficiency, the wireless device may indicate a first CQI index, for a second calculated spectral efficiency, the wireless device may indicate a second CQI index, and so on. Each index of the CQI may be associated with an MCS. For example, a first index may be associated with a first modulation (e.g., 16-quadrature amplitude modulation (QAM)) and a first coding rate (e.g., a .438 coding rate), a second index may be associated with the same or a different modulation (e.g., 16-QAM or 64-QAM) and a second coding rate (e.g., a .587 coding rate when the second index is associated with 16-QAM, or a .369 coding rate when the second index is associated with 64-QAM), and so on.

[0080] The other wireless device may receive the indication of the preferred transmission parameters and may use the indicated transmission parameters (or related transmission parameters) for subsequent communications to the wireless device. In some examples, the other wireless device may select the MCS based on the value of the CQI. For example, where the first index is indicated by the CQI, the other wireless device may use a first modulation (e.g., 16-QAM) and a first coding rate (e.g., .438 coding rate) for subsequent transmissions to the wireless device.

[0081] Wireless devices such as UE 115 and network entity 105 may support various types of modulation and coding procedures to provide different levels of error protection for coded transmissions. For example, a device may implement LDPC coding to perform channel coding and decoding. However, in some cases, this type of channel coding utilizes a large amount of power (e.g., an amount of power above a threshold). In order to reduce power consumption, a device may implement different types of coding procedures such as MLC, where coding and decoding may be split into multiple levels so that different component codes (e.g., code rates or modulation orders) are applied to non-overlapping sets of bits. In order to perform MLC, UE 115 may select a CQI index corresponding to the modulation order and coding scheme for each code level. However, since MLC constitutes at least two code levels, the number of possible MCS combinations is wide because the selected CQI index will correspond to the modulation order and coding scheme for each code level used for MLC.

[0082] In order to more efficiently report CQI to select the modulation order and coding rate values ​​for MLC, the UE 115 may select and report one CQI value per code level of the MLC procedure (e.g., rather than transmitting a single CQI value to select both the modulation order and coding rate values). For example, for a first coding level, the UE 115 may select a first CQI index associated with a first modulation order and a first coding rate from a first CQI table, and then for a second coding level, the UE may select a second CQI index associated with a second coding rate from a second CQI table. The UE reports the selected CQI indexes to the network entity 105 and may receive subsequent control signaling from the network indicating which CQI indexes were selected and which corresponding MCS values ​​to use for each level of MLC.

[0083] Figure 2 An example of a wireless communication system 200 that supports dynamic reporting of MLC configurations according to one or more aspects of the present disclosure is illustrated. For example, Figure 2 The communication between UE 115-a and network entity 105-a may be illustrated, which may be referenced Figure 1 Examples of corresponding devices described.

[0084] The wireless communication system 200 may support a set of modulation and decoding procedures for communicating information between wireless devices such as UE 115-a and network entity 105-a in wireless coverage area 210. Different modulation procedures (e.g., PSK, QAM, etc.) may be used to convert a set of information bits into unique data symbols. Different decoding procedures may be used to protect the information bits from errors that may occur during the transmission of the information bits. In some examples, the wireless communication system 200 may support decoding of channel codes using a low-density parity-check decoding (LDPC) scheme, which is a linear error correction code that can be decoded linearly in time with the code block length. However, in some cases, LDPC decoding is complex and relatively power-consuming for the UE to perform for the downlink reception process. For example, in some specific implementations, LDPC power consumption in the SubThz downlink band may account for a relatively large portion of the total power consumption of the device modem (e.g., the power consumed by LDPC decoding may reach 90% of the total power consumption).

[0085] For systems supporting increased bandwidth (e.g., 5G NR systems or other high frequency systems), this increased power expenditure for LDPC decoding is amplified. Additionally, in wireless systems where data rates and bit rates may be substantially increased relative to other lower bandwidth systems, power expenditure may become even more significant as bandwidth continues to grow (e.g., for SubThz bands).

[0086] In order to reduce the total power expenditure for decoding, the device may implement one or more different decoding procedures. For example, UE115-a may implement MLC procedure 205 to provide error protection while increasing power savings. MLC procedure 205 may provide different levels of error protection by corresponding to different points in the symbol constellation and therefore corresponding to different bits of the transmitted symbol. During MLC procedure 205, information bits may be grouped according to the configured modulation protocol, the grouped information bits may be divided into subsets of bits associated with different decoding levels, and different component codes may be applied to different subsets of bits according to different decoding levels. In some examples, each decoding level may correspond to different assignments of different component codes for non-overlapping subsets of bits (e.g., the marker bits corresponding to the points of the symbol constellation may be divided into marker bit subsets associated with different decoding levels, where different component codes may be associated with different subsets of marker bits). The sum of the bits in each decoding level may be equal to the number of bits included in the original symbol marker. Thus, MLC may result in unequal error protection for different bits because different subsets of bits may be encoded with different component codes that provide varying levels of protection.

[0087] Different methods can be used to decode the received MLC-based coded information. One method for decoding the MLC-based coded information is a multi-stage decoding (MSD) procedure. The MSD procedure may involve decoding a first subset of the received MLC-based coded information according to a first component code and then decoding a second subset of the received MLC-based coded information according to a second component code and based on the result of decoding the first subset of the received MLC-based coded information. That is, the MSD procedure may involve decoding the bits associated with the second level after decoding the bits associated with the first level. Another method for decoding the MLC-based coded information is a parallel independent decoding (PID) procedure. The PID procedure may involve decoding each subset of the received MLC-based coded information associated with each level independently of each other. That is, when decoding the information bits associated with the second coding level, the decoding of the information bits associated with the first coding level may not be used.

[0088] In an example, the bit string (e.g., 00100010) of the MLC protocol 205 may be divided into different component codes and corresponding different decoding levels. For example, the first decoding level (e.g., component code 1, level 1) may implement an MSD decoding procedure, which may include decoding the MLC level based on knowledge (segmentation information) obtained from decoding of the previous level. In such a case, the bit string 00100010 may be divided into two levels, and the segmented codes may be decoded such that the second half (0010) of the bit string is decoded after the first half (0010). In the second decoding level (e.g., component code 2, level 2), the MLC protocol may implement a PID, where decoding each MLC level is done independently without applying knowledge obtained from decoding of the previous level (no subset segmentation).

[0089] In some examples, the execution of the MLC procedure 205 may be based on a method or technique for marking points of a symbol constellation, a method for partitioning marking bits, a method for encoding different levels, the quality of a communication channel, or any combination thereof. In some examples, the execution of MLC-based coded communications may be based on characteristics of the channel over which the MLC-based coded communications are communicated (e.g., channel type) and a method for decoding MLC-based coded communications. For example, the MSD procedure may improve the performance of MLC-based coded transmissions performed over an additive white Gaussian noise channel (AWGN). The PID procedure may improve the performance of MLC-based coded transmissions performed over a fading channel.

[0090] In some examples, the MLC protocol 205 can improve the spectral efficiency of communications relative to other decoding or encoding protocols. For example, the number of bits and the selected code rate for each MLC code level can be dynamically adjusted for different signal-to-noise ratio (SNR) regions to improve spectral efficiency. In addition, when using an MLC protocol including a non-decoded minimum level, power consumption of MLC-based coded transmissions can be reduced relative to other decoding schemes (e.g., especially for large bandwidths). Therefore, in order to achieve different levels of error protection for different bits in a symbol, the wireless communication system 200 can support the MLC protocol.

[0091] In order to support the use of the MLC procedure, a mechanism (e.g., new signaling, updated signaling, signaling exchange, etc.) that supports the use of the MLC procedure 205 may be established. In some examples, a set of CQI indexes that can be selected for CQI and associated with an MLC-based MCS (and associated MCS table) may be established. The UE 115-a and the network entity 105-a may exchange capability information indicating support for the MLC procedure. In some examples, the network entity 105-a may indicate that an extended CQI table that may correspond to an extended MCS table is activated. When the MLC procedure is enabled, the UE 115-a may select different CQI and MCS values ​​from corresponding tables that can be used to indicate modulation, total code rate, decoding method, the number of levels used for the MLC procedure 205, the number of bits included in each level, and the code rate for each level.

[0092] However, since the MLC procedure consists of at least two code levels, the number of possible MCS combinations may be wide or exceed a threshold number of combinations. In such cases, using a single MCS table for selecting an MLC MCS value may be inefficient because a large number of combinations of MCS index, modulation order, and coding rate are possible in multiple code level situations. Therefore, in order to improve the efficiency and reduce the complexity of UE reporting of CQI and associated MCS for MLC, UE 115-a may support configuration and signaling of UE reports (e.g., CQI reports, PMI reports, RI reports) that dynamically request the desired MLC MCS per decoding level by reporting a CQI index 215 per decoding level (rather than reporting a single value for CQI to select the desired MCS from the MCS table). In addition, reporting the CQI index 215 and associated MCS per decoding level for MLC may allow the network to optimize UE power consumption for current channel conditions and UE hardware when using MLC to reduce channel decoding power.

[0093] In the first reporting configuration, the UE may report a per-code level CQI index 215 associated with the MLC configuration in the CSI report 220. In such a case, each CQI value corresponds to a different MCS (e.g., rather than transmitting a single CQI value to select multiple MCS values ​​from a selected MCS table). The selection of per-code level CQI may improve both spectral efficiency and power consumption of the UE. Tables 1 and 2 illustrate examples of possible CQI indices and corresponding modulation orders and code rates that may be selected for a two-level MLC procedure:

[0094]

[0095]

[0096] Table 1: Indexes for level 1

[0097] The UE 115-a may select a first CQI index 215-a for level 1 of the MLC procedure using Table 1, which may correspond to modulation orders and code rates. The UE 115-a may then select a second CQI index 215-b for level 2 of the MLC procedure using Table 2 below.

[0098] Index for level 2 Bitrate 0 0.8 1 0.85 2 0.9 3 0.95

[0099] Table 2: Indexes for level 2

[0100] The second CQI index 215-b may correspond to a code rate. In some examples, Table 1 and Table 2 may be different sizes (e.g., Table 1 and Table 2 may have different numbers of columns, different numbers of rows, or both), or may be the same size. In some cases, UE 115-a may select different combinations of indexes based on power savings. For example, different combinations of indexes may result in the same spectral efficiency, but may have different levels of power savings, and UE 115-a may select a combination of indexes 215 for level 1 and level 2 that results in the relatively highest amount of power savings for UE 115-a.

[0101] In a second reporting configuration, the UE 115-a may report an explicit (e.g., quantized) vector or rate for each coding level associated with the MLC configuration in the CSI report 220. In such a case, the UE 115-a may report quantized values ​​of the MCS (e.g., different quantized values ​​for code rates and modulation orders for different CQI indices 215). The UE 115-a may use a set of tables to select the quantized values. Tables 3, 4, and 5 illustrate examples of possible CQI indices 215 and corresponding quantized values ​​for code rates and modulation orders that may be selected for a two-level MLC procedure:

[0102] Index for level 1 Bitrate 0 0.3 1 0.44 2 0.59 3 0.65 4 0.72 5 0.8 6 0.86 7 0.92

[0103] Table 3: Indexes for level 1

[0104] Index for level 2 Bitrate 0 0.8 1 0.85 2 0.9 3 0.95

[0105] Table 4: Indexes for level 2

[0106] Index for level 2 Modulation order 0 2 1 4 2 6 3 8

[0107] Table 5: Indexes for level 2

[0108] UE 115-a may select a first CQI index for level 1 of the MLC procedure using Table 3, which may correspond to a code rate. UE 115-a may then select a second CQI index for level 2 of the MLC procedure using Table 4, which may correspond to a code rate for level 2. UE 115-a may select a CQI index for level 2 of the MLC procedure using Table 5, which may correspond to a modulation order for level 2. In some examples, Table 3, Table 4, and Table 5 may be different sizes (e.g., Table 3, Table 4, and Table 5 may have different numbers of columns, different numbers of rows, or both), or may be the same size. In some cases, the UE may select different combinations of indexes based on power savings. For example, different combinations of indexes may result in the same spectral efficiency, but may have different levels of power savings, and the UE may select a combination of indexes for level 1 and level 2 that results in the relatively highest amount of power savings for the UE.

[0109] The network may activate the MLC procedure for transmission to UE 115-a based on the CQI index received from UE 115-a. In some examples, the network entity may indicate to UE 115-a that the MLC procedure has been activated (e.g., by indicating a CQI index associated with the MLC procedure in a downlink control information (DCI) message 225 transmitted to the UE). In some examples, the network entity 105-a may indicate that the MLC process has been activated (or enabled) by sending a DCI message, an RRC message, or a MAC-CE that configures UE 115-a to use the MLC procedure. In some other examples, the network entity may send a modified DCI to indicate the selected CQI index that determines the MLC MCS. In some specific implementations, the network entity may report different MLC MCS indexes based on the reporting time granularity. For example, the modulation order may be modified more frequently than other indexes that control the rates of different decoding levels at a lower frequency. Dynamic reporting of CQI for MLC may reduce complexity and may increase power savings at UE 115-a.Additionally or alternatively, even though the described techniques are related to downlink MLC implementation, the techniques and configuration of MLC MCS described herein may also be applicable to uplink communications.

The process flow 300 may be performed by a network entity 105-b and a UE 115-b, which may be reference Figure 1 and Figure 2 Examples of network entities and UEs described herein. In some examples, process flow 300 illustrates an exemplary sequence of operations performed to support dynamic reporting of MLC configurations. It will be understood that one or more operations described in process flow 300 may be performed earlier or later in the process, omitted, replaced, supplemented, or combined with another operation. In addition, additional operations described herein that are not included in process flow 300 may be included in process flow 300.

[0111] At 305, UE 115-b may receive a message indicating decoding procedures for communications associated with UE 115-b.

[0112] At 310, the network entity 105-b may activate a multi-level coding procedure for communicating with the UE 115-b, and at 315, the network entity 105-b may optionally signal an indication of the activation of the MLC procedure to the UE 115-b.

[0113] At 320, UE 115-b may select a first rate indicator value from among a plurality of rate indicator values, the first rate indicator value corresponding to a first rate for a first decoding level for a decoding procedure. UE 115-b may also select a second rate indicator value from among a plurality of rate indicator values, the second rate indicator value corresponding to a second rate for a second decoding level for a decoding procedure. In some examples, UE 115-b may select the first rate indicator value and the second rate indicator value based on a spectral efficiency value for communicating data, a power consumption value for communicating data, or both. For example, in some cases, UE 115-b may select the first rate indicator value and the second rate indicator value for a decoding procedure based on the spectral efficiency value satisfying a spectral efficiency threshold and the power consumption value satisfying a power consumption threshold. In some examples, different combinations of the first rate indicator value and the second rate indicator value correspond to different spectral efficiency values ​​and different power consumption values.

[0114] In some examples, UE 115-b may select a first rate indicator value from a first CQI table. For example, the first CQI table may include a plurality of rate indicator values ​​associated with a first coding level, a first set of one or more corresponding modulation orders, a first set of one or more corresponding code rates, or any combination thereof. UE 115-b may also select a second rate indicator value from a second CQI table that includes a plurality of rate indicator values ​​associated with a second coding level and a second set of one or more corresponding code rates. In some cases, the first CQI table and the second CQI table may have different numbers of rows and columns based on the first coding level and the second coding level.

[0115] In some examples, UE 115-b may select a first rate indicator value from a first CQI table that includes a first set of multiple rate indicator values ​​and corresponding code rates associated with a first coding level. UE 115-b may then select a second rate indicator value from a second CQI table that includes a second set of multiple rate indicator values ​​and one or more corresponding code rates associated with a second code rate. UE 115-b may also select a third rate indicator value from a third CQI table that includes a modulation order associated with the first rate indicator value and the second rate indicator value. In such cases, the first CQI table, the second CQI table, and the third CQI table may have different numbers of rows and columns based on the first coding level and the second coding level.

[0116] At 325, UE 115-b may send a coding level indicator report that includes a plurality of code rate indicator values ​​associated with the coding procedure, including the selected first code rate indicator value and the selected second code rate indicator value. In some examples, the coding level indicator report may be a CQI report, a PMI report, an RI report, or another type of UE report.

[0117] At 330 , the network entity 105 - b may select an MCS value corresponding to the selected first code rate indicator and the selected second code rate indicator based on the received coding level indicator report.

[0118] At 335, the network entity 105-b may send a message to the UE 115-b indicating the selected CQI index and the associated MCS value based on the coding level indicator report. For example, the UE 115-b may receive one or more control messages (e.g., DCI, MAC-CE, RRC message, etc.) indicating a set of code rate indicator values ​​for use by the UE, the set of code rate indicator values ​​corresponding to a first code rate for a first coding level for a coding procedure and corresponding to a second code rate for a second coding level for the coding procedure. In some other examples, the one or more control messages may be based on a reporting granularity associated with the first code rate and the second code rate.

[0119] At 340, the UE 115-b and the network entity 105-b may communicate at least one data packet using the MLC procedure. In some examples, the UE 115-b may encode or decode a first subset of bits according to a first code rate for a first coding level for the coding procedure, and may encode or decode a second subset of bits according to a second code rate for a second coding level for the coding procedure.
