[0003] The following pertains to wireless communication, including code design for non-uniform sources. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (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 technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each supporting wireless communication for communication devices, which may be referred to as User Equipment (UE).

[0042] In some wireless communication systems, a first device may use an encoding matrix (e.g., a low-density parity-check (LDPC) encoding matrix) to encode a message. The encoding matrix can support error detection and correction at a second device. The encoding matrix may include: a set of information columns including system bits, a first set of core parity columns including a first set of parity bits, and one or more sets of extended parity columns including a second set of parity bits. The first device may use a circular buffer to encode the message, where the buffer iterates through the columns of the encoding matrix (e.g., each index of the circular buffer corresponds to a column in the encoding matrix). In some cases, the message may have a non-uniform probability of 0 and 1 bits (e.g., the UE may have a higher probability of sending 0 bits than 1 bits). If the message is non-uniform (e.g., unequal 0 and 1 bits), the corresponding encoded message encoded using the system bits of the encoding matrix may also be non-uniform. The first device may send a non-uniformly encoded message to the second device. Sending a non-uniform message may reduce the efficient utilization of communication resources compared to a uniform message.

[0043] According to the techniques described herein, a first device can encode a non-uniform message using an encoding matrix, and the first device can puncture a portion of the encoded message generated using the system bits of the encoding matrix. For example, the first device can encode the message based on an offset value associated with an initial column of the encoding matrix. The initial column can be associated with a first set of core parity columns or one or more sets of extended parity columns. The first device can begin encoding the message at the initial column and puncture at least some of the system bits. The first device can send a portion of the encoded message generated using the parity bits (e.g., a non-punctured portion) to a second device. By puncturing at least some of the system bits and encoding the message using parity bits, the encoded message can be more uniform. Sending a uniform message improves the efficient utilization of communication resources compared to a non-uniform message.

[0044] In some examples, the first device may perform a first encoding process on a non-uniform message using a first portion of the encoding matrix (e.g., a low-density generator matrix (LDGM) or LDPC), and the first device may perform a second encoding process on the output from the first encoding process using a second portion of the encoding matrix (e.g., a corresponding LDGM or LDPC). The second encoded message may be more uniform than the first encoded message.

[0045] The aspects of this disclosure are first described in the context of wireless communication systems. These aspects are further illustrated and described by way of apparatus diagrams, system diagrams, and flowcharts relating to code design for non-uniform sources.

[0046] Figure 1 An example of a wireless communication system 100 supporting code design for non-uniform sources according to one or more aspects of this disclosure is shown. The wireless communication system 100 may include one or more devices, such as one or more network devices (e.g., network entity 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 under other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0047] Network entity 105 may be distributed across a geographical area to form wireless communication system 100, and may include devices employing different forms or having different capabilities. In various examples, network entity 105 may be referred to as a network element, mobility element, radio access network (RAN) node, or network equipment, etc. In some examples, network entity 105 and UE 115 may wirelessly communicate via communication link 125 (e.g., a radio frequency (RF) access link). For example, network entity 105 may support coverage area 110 (e.g., a geographical coverage area) within which UE 115 and network entity 105 may establish communication link 125. Coverage area 110 may be an example of a geographical area within which network entity 105 and UE 115 may support the transmission of signals according to one or more radio access technologies (RATs).

[0048] UE 115 can be distributed throughout the coverage area 110 of wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. UE 115 can be devices in different forms or with different capabilities. Figure 1 Examples of UE 115 are illustrated herein. The UE 115 described herein may be able to support communication with various types of devices in the wireless communication system 100 (e.g., other wireless communication devices, including UE 115 or network entity 105), such as... Figure 1 As shown.

[0049] As described herein, a node in the wireless communication system 100 (which may be referred to as a network node or 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, apparatus, device, computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be UE 115. As another example, a node may be 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 UE 115, the second node may be network entity 105, and the third node may be UE 115. In another aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different from these examples. Similarly, references to UE 115, network entity 105, device, equipment, computing system, etc., may include disclosures of UE 115, network entity 105, device, equipment, computing system, etc., as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that a first node is configured to receive information from a second node.

[0050] In some examples, network entity 105 may communicate with core network 130, communicate with each other, or both. For example, network entity 105 may communicate with core network 130 via backhaul communication link 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entities 105 may communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication link 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, network entities 105 may communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be one or more wired links (e.g., electrical links, fiber optic links) or one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof, or may include one or more wired links (e.g., electrical links, fiber optic links) or one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 may communicate with the core network 130 via communication link 155.

[0051] One or more network entities or network equipment described herein as network entity 105 or network equipment may include or be referred to as base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, node B, eNodeB (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home node B, home evolution node B, or other suitable terms). In some examples, network entity 105 (e.g., base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture that may be configured to utilize a protocol stack physically or logically integrated within a single network entity (e.g., network entity 105 or a single RAN node, such as base station 140).

[0052] In some examples, network entity 105 may be implemented in a decomposed architecture (e.g., a decomposed base station architecture, a decomposed RAN architecture) that can be configured to utilize protocol stacks physically or logically distributed across multiple network entities (e.g., network entity 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, network entity 105 may include one or more of the following: a Central Unit (CU) such as CU 160, a Distributed Unit (DU) such as DU 165, a Radio Unit (RU) such as RU 170, a RAN Intelligent Controller (RIC) such as 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) system such as SMO system 180, or any combination thereof. RU 170 may also be referred to as a radio headend, intelligent radio headend, remote radio headend (RRH), remote radio unit (RRU), or transmit / receive point (TRP). One or more components of network entity 105 in a decomposed RAN architecture may be co-located, or one or more components of network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities in network entity 105 of a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0053] The functional splitting among CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a protocol stack functional splitting can be used between CU 160 and DU 165, allowing CU 160 to support one or more layers of the protocol stack, and DU 165 to support one or more different layers of the protocol stack. In some examples, CU 160 can host upper protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionality and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 (e.g., one or more CUs) may connect to DU 165 (e.g., one or more DUs) or RU 170 (e.g., one or more RUs) or a combination thereof, and DU 165, RU 170, or both 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 CU 160. Additionally or alternatively, a protocol stack functional split may be employed between DU 165 and RU 170, such that DU 165 may support one or more layers of the protocol stack, and RU 170 may support one or more different layers of the protocol stack. DU 165 may (e.g., via one or more different RUs, such as RU 170) support one or more different cells. In some cases, functional decomposition between CU 160 and DU 165, or between DU 165 and RU 170, can be performed 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 can be performed by a different one of CU 160, DU 165, or RU 170). CU 160 can be further functionally decomposed into CU control plane (CU-CP) functions and CU user plane (CU-UP) functions. CU 160 can be connected to DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to RU 170 via fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, the midhaul communication link 162 or the fronthaul communication link 168 may be implemented based on the interfaces (e.g., channels) between the layers of the protocol stack, which are supported by corresponding network entities (e.g., one or more network entities in network entity 105) that communicate via such communication links.

[0054] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access can 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 of network entity 105 (e.g., network entity 105 or IAB node 104) may be partially controlled by each other. IAB node 104 may be referred to as a donor entity or IAB donor. DU 165 or RU 170 may be partially controlled by CU 160 associated with network entity 105 or base station 140 (such as a donor network entity or donor base station). One or more donor entities (e.g., IAB donors) may communicate with one or more additional devices (e.g., IAB node 104) via supported access and backhaul links (e.g., backhaul communication link 120). IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DU 165) of a coupled IAB donor. The IAB-MT may be equipped with a separate set of antennas for relaying communication with UE 115, or may share the same antennas (e.g., those of RU 170) for access to IAB node 104 via DU 165 of IAB node 104. (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, IAB node 104 may include one or more DUs (e.g., DU 165) that support 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., IAB node 104, or components of IAB node 104) may be configured to operate according to the techniques described herein.

[0055] When the techniques described herein are applied in the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture can be configured to support the tests described herein. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., components such as IAB node, DU 165, CU 160, RU 170, RIC 175, SMO system 180).

[0056] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in various objects such as appliances, vehicles, or meters.

[0057] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes operate as repeaters, 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 As shown.

[0058] UE 115 and network entity 105 can wirelessly communicate with each other via communication link 125 (e.g., one or more access links) using resources associated with one or more carriers. The term "carrier" can refer to a set of RF spectrum resources having a defined PHY layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the RF spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR). Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured using multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers. Communication between network entity 105 and other devices can refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms “send,” “receive,” or “communicate” when referring to network entity 105 can refer to any part of the RAN’s network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities, such as one or more network entities in network entity 105).

[0059] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and 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 decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high modulation scheme order correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal 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.

[0060] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period. seconds, in response This can represent the supported subcarrier spacing, while It can represent the supported Discrete Fourier Transform (DFT) size. Time intervals for communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0061] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems, such as wireless communication system 100, time slots may be further divided into multiple 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., The duration of a symbol period is associated with a (number) sampling period. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0062] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0063] Depending on the technology, carriers can be used to multiplex physical channels for communication. One or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used, for example, to multiplex physical control channels and physical data channels for signaling via a downlink carrier. The control region (e.g., control resource set (CORESET)) of the physical control channel can be defined by a set of symbol periods and can extend across the system bandwidth of the carrier or a subset of that bandwidth. One or more control regions (e.g., CORESET) can be configured for a set of UEs 115. For example, one or more UEs in UE 115 can monitor or search for control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a concatenated manner. The aggregation level of control channel candidates can 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 set may include a common search space set configured to transmit control information to UE 115 (e.g., one or more UEs), or it may include a UE-specific search space set configured to transmit control information to UE 115 (e.g., a particular UE).

[0064] In some examples, network entity 105 (e.g., base station 140, RU 170) may be mobile, and thus provide communication coverage to mobile coverage areas (such as coverage area 110). In some examples, coverage areas 110 associated with different technologies (e.g., different coverage areas) may overlap, but coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., network entity 105). In some other examples, overlapping coverage areas (such as coverage area 110) associated with different technologies may be supported by different network entities (e.g., network entity 105). The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 use the same or different RATs to support communication to coverage areas 110 (e.g., different coverage areas).

[0065] Wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communication may include private 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 prioritizing services, and such services may be used for public safety or general business applications. The terms “ultra-reliable,” “low-latency,” and “ultra-reliable low-latency” are used interchangeably herein.

[0066] In some examples, UE 115 may be configured to support direct communication with other UEs (e.g., one or more UEs in UE 115) via a device-to-device (D2D) communication link (such as 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 performing D2D communication may be within the coverage area 110 of network entity 105 (e.g., base station 140, RU 170), which may support aspects of such D2D communication configured (e.g., scheduled by network entity 105). In some examples, one or more UEs 115 in this group may be outside the coverage area 110 of network entity 105, or may otherwise be unable or not configured to receive transmissions from network entity 105. In some examples, a group of UEs 115 communicating via D2D communication can support a one-to-many (1:M) system, in which each UE 115 transmits to one or more UEs in the group. In some examples, network entity 105 can facilitate the scheduling of resources used for D2D communication. In some other examples, D2D communication can be performed between UEs 115 without involving network entity 105.

[0067] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), 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), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) for routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by network entity 105 (e.g., base station 140) associated with core network 130. User IP packets can be transferred through user plane entities, which provide IP address allocation and other functions. User plane entities can connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0068] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the area from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) band or decimeter band because the wavelength range is approximately 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 are sufficient to penetrate structures so that macrocells can provide service to UE 115 located indoors. Compared to communication using smaller frequencies and longer wavelengths in the lower frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, communication using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers).

[0069] Wireless communication system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may employ licensed assisted access (LAA), LTE-Unlicensed (LTE-U) RAT, or NR technology using unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating with unlicensed RF spectrum, devices such as network entity 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation using unlicensed frequency bands may be based on carrier aggregation configurations combined with component carriers operating with licensed frequency bands (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0070] 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 techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with network entity 105 may be located at different geographical locations. Network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that network entity 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0071] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., network entity 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating along a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of these antenna elements may be defined by a beamforming weight set associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device or relative to some other orientation).

[0072] UE 115 and network entity 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correctly receiving data via communication links (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under relatively poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device may support same-slot HARQ feedback, in which case the device can provide HARQ feedback in a specific time slot for data received via a previous symbol in that time slot. In some other examples, the device may provide HARQ feedback in subsequent time slots or according to a different time interval.

[0073] In some wireless communication systems, a first device (e.g., UE 115 or network entity 105) may send non-uniform messages (e.g., messages containing unequal proportions of 1 and 0 bits) to a second device (e.g., UE 115 or network entity 105). For example, the first device may send HARQ feedback. Non-uniform message probabilities can occur in HARQ feedback communication scenarios. The first device may send an acknowledgment (ACK) or a negative acknowledgment (NACK), where an ACK (e.g., bit 0) may be more likely than a NACK (e.g., bit 1). In other words, the first device can indicate acknowledgment of a received message by setting the corresponding feedback bit to 0 (e.g., ACK), and the first device can indicate an error in receiving or decoding a message by setting the corresponding feedback bit to 1 (e.g., NACK). In some cases, the first device may be more likely to send an ACK than a NACK. For example, a 10% block error rate (BLER) in a PDSCH (e.g., 10% of the code blocks associated with PDSCH transmission may contain errors) may correspond to a 10% NACK probability and a 90% ACK probability. In other words, the first device can send approximately 10% of 1 bits and 90% of 0 bits based on 10% BLER. In HARQ feedback communication, the second device can schedule one or more messages (e.g., downlink messages), and the first device can send HARQ feedback for one or more messages. For example, the second device can schedule four downlink transmissions (e.g., PDSCH). The first device can transmit a 4-bit message for HARQ ACK / NACK (e.g., HARQ feedback) based on the decoding of the downlink transmissions. In some cases, the Channel State Information (CSI) can resemble HARQ-ACK (e.g., the distribution of cached and downlink resource sharing optimization framework (CSF) bits can be non-uniform).

[0074] In some examples, the first device may send non-uniform messages that include semantic data communication (e.g., semantic data communication for sending voice or images). The messages may include residual redundancy, and the messages may be non-uniform based on residual redundancy.

[0075] Alternatively or additionally, the first device may send a non-uniform message based on the conditional distribution of the first device, given the side information at the second device. In many applications, the second device may already have side information about the first device, which can be used at the second device to facilitate decoding. That is, even if the original distribution at the first device may be uniform, the message may still be non-uniform based on the side information at the second device.

[0076] In some cases, the output from the first device can utilize a Bernoulli distribution (e.g., a series of independent and identically distributed (iid) Bern(p) information bits). We can model it using the following method. For example, when p=0.11, the entropy H(0.11) can be 0.5. In the case of uniform iid, when p=0.5, the entropy H(0.5) can be 1.

[0077] According to the techniques described herein, a first device can encode a non-uniform message using an encoding matrix, and the first device can puncture a portion of the encoded message generated using the system bits of the encoding matrix. For example, the first device can encode the message based on an offset value associated with an initial column of the encoding matrix. The initial column can be associated with a first set of core parity columns or one or more sets of extended parity columns. The first device can begin encoding the message at the initial column and puncture one or more system bits. The first device can send a portion of the encoded message generated using the parity bits (e.g., a non-punctured portion) to a second device. By puncturing the system bits and encoding the message using parity bits, the encoded message can be more uniform (e.g., compared to non-uniform information in an unencoded message). Sending a uniformly encoded message improves the efficient utilization of communication resources compared to an unencoded non-uniform message.

[0078] In some examples, the first device may perform a first encoding process on a non-uniform message using a first portion of the encoding matrix (e.g., LDGM or LDPC), and the first device may perform a second encoding process on the output from the first encoding process using a second portion of the encoding matrix (e.g., corresponding to LDGM or corresponding to LDPC). The second encoded message may be more uniform than the first encoded message.

[0079] Figure 2Examples of a wireless communication system 200 supporting code design for non-uniform sources according to one or more aspects of this disclosure are shown. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. For example, a first device 205-a and a second device 205-b may represent a UE (such as a reference UE). Figure 1 The described UE 115) or network entity (such as reference) Figure 1 Examples of network entities 105 described herein. The first device may utilize encoding matrix 210 and may include buffer 215 (e.g., a circular buffer). In some cases, the second device may utilize encoding matrix 210 and buffer 215, or a decoder based on encoding matrix 210 (not shown). The first device 205-a may communicate with the second device 205-b via communication channel 220.

[0080] The first device can generate an encoding matrix 210 and encode the first message according to the LDPC encoding process. The encoding matrix 210 may include: a set of information columns 225 including system bits, a set of core parity columns 230 including a first set of parity bits, and one or more sets of extended parity columns 235 including a second set of parity bits. The core matrix of the encoding matrix 210 may include a set of information columns 225 and a set of core parity columns 230 in a core parity row 240. The core matrix can be used for encoding at a high code rate. The extended parity columns 235 may include an identity matrix structure in the extended row 245. The extended row 245 may include a first degree-one extension (e.g., a first extended row). The first degree-one extension may be special extension bits. The extended parity columns 235 may be connected to either the information columns 225 or the core parity columns 230. In some cases, the extended parity columns may not be connected to another extended parity column (e.g., another extended parity node). For example, the first device 205-a can use the core matrix at a first code rate to generate a first encoded message of the first message (e.g., redundant version (RV) 0). For retransmission of the first message, the first device 205-a can use an extended portion of the encoding matrix 210 (e.g., extending parity column 235 or extending row 245) at a second code rate lower than the first code rate to generate a second encoded message of the first message (e.g., RV1). The first device 205-a can combine the first encoded message and the second encoded message (e.g., providing more parity bits). In some examples, each additional retransmission may include an additional portion (e.g., extending parity column 235 or extending row 245) and an increased number of parity bits.

[0081] Encoded messages (e.g., RV0 or RV1) may be associated with an initial column of the encoding matrix. For example, a first encoded message may be associated with a first column in a set of information columns 225 (e.g., the starting column of encoding matrix 210). A second encoded message may be associated with a second column in a set of information columns 225 (e.g., column 260). In some cases, the second column may be associated with an index value larger than the first column. A third encoded message (e.g., RV2 or a second retransmission of the first message generated at the first device 205-a) may be associated with a third column in a set of core parity columns 230.

[0082] Circular buffer 215 may include an index 250 associated with an initial column of encoding matrix 210 (e.g., for a corresponding RV or retransmission). For example, index 250-a may be associated with a first column in a set of information columns 225 associated with a first encoded message (e.g., RV0). If the initial column of the first encoded message (e.g., RV0) is indicated as the first column in information columns 225 (e.g., the leftmost starting column of information columns 225), the first few bits of the first encoded message may include system bits within the range 255 of the first information column in information columns 225. Index 250-b may be associated with a second column in a set of information columns 225 associated with a second encoded message (e.g., RV1). Index 250-c may be associated with a third column in a set of core parity columns 230 associated with a third encoded message (e.g., RV2). Index 250-d may be associated with a fourth column in a set of extended parity columns 235 associated with a fourth encoded message (e.g., RV3). Range 255 may represent index 250 in buffer 215 associated with information column 225. For example, the first encoded message associated with index 250-a may be associated with index 250-a (e.g., index 250 associated with the starting column of encoding matrix 210) and up to index 250-b (e.g., index 250 associated with column 260 of information column 225). Index 250 including index 250-a and up to index 250-b may all be associated with information columns of encoding matrix 210 (e.g., the columns of encoding matrix 210 between the starting column and column 260 are all columns in a set of information columns 225). The second encoded message associated with index 250-b may be associated with index 250, which includes index 250-b (e.g., index 250 associated with column 260) and extends up to index 250-c (e.g., index 250 associated with either core parity column 230 or extended parity column 235).

[0083] In some cases, the first device 205-a may generate an encoding matrix 210 based on a non-uniform message for transmission to the second device 205-b. The first device 205-a may use the encoding matrix 210 to encode the non-uniform message. For initial transmission, the encoded message may be associated with RV0. That is, the first device 205-a may generate a first encoded message based on the system bits associated with information column 225. Based on the non-uniform message, the system bits may be non-uniform, and based on the non-uniform system bits, the first encoded message may be non-uniform. The first device 205-a may transmit the first non-uniform encoded message via communication channel 220. The non-uniformity of the first encoded message can cause performance degradation on channel 220. For example, some encoding (e.g., and corresponding decoding) processes may be based on the underlying assumption that 0 bits and 1 bits are equally likely, and therefore may experience degradation or failure when the source is non-uniform. For example, if the assumption of uniform bits is false, communication via communication channel 220 may be degraded, and channel capacity may be reduced when the first device transmits a non-uniform message.

[0084] Communication channel 220 can be symmetric, and the channel distribution associated with communication channel 220 can be a Gaussian distribution (e.g., a distribution symmetric around zero). Non-uniform bits can be mapped non-uniformly to the modulation scheme. Non-uniform mapping can produce an asymmetric input distribution, which can reduce the channel capacity of symmetric channels (e.g., additive white Gaussian noise (AWGN) channels).

[0085] According to the techniques described herein, the first device 205-a and the second device 205-b can utilize a decoding process associated with a non-uniform message (e.g., an LDPC decoding process) to generate a uniform encoded message (e.g., based on a decoding matrix 210 generated from a non-uniform uncoded message). In some cases, the LDPC code can be an example of an LDGM structure (e.g., LDPC+degree 1 extension). That is, the encoding matrix 210 can be associated with an LDPC code.

[0086] In some cases, to generate a coded uniform message while mitigating the non-uniformity of the uncoded message associated with the non-uniform message, the first device 205-a may transmit the parity portion (e.g., code) of the coding matrix 210 as an initial transmission, and the first device 205-a may punch some or all of the system bits from the initial transmission. Based on the modulo-2 summation used to generate the parity bits, the parity portion of the coding matrix 210 can be more uniform. The first device may transmit the initial transmission generated using the parity portion of the coded matrix 210 via communication channel 220. The increased uniformity can increase the channel capacity associated with communication channel 220. That is, the initial transmission may use a special RV (e.g., RV2). The first transmission (e.g., instead of RV0, which includes or starts from system bits) may be a special RV or a different RV (e.g., a coded message associated with a second retransmission of the non-uniform message that starts from or includes parity bits). RV2 can start from the halfway point of the encoding matrix (e.g., RV2 can be associated with the third column in a set of core parity columns 230).

[0087] In some examples, to generate an initial transmission, the first device may use one or more columns from the columns associated with RV0, RV1, and RV2 (e.g., the columns associated with indices 250-a to 250-d) to encode a non-uniform message. The first device may puncture the bits associated with RV0 and RV1. That is, the first device 205-a may puncture all the system bits, or the first device 205-a may puncture all the system bits and some of the parity bits (e.g., the core parity bit associated with RV1), and alternatively transmit the parity bit (e.g., as the start column of the encoded message). For example, the first device 205-a may transmit the parity portion of the code as an initial transmission, and may puncture the system bits (e.g., transmit the parity bit instead of the system bits at the beginning of the encoded message).

[0088] In some cases, the initial transmission may be based on a new RV or a dedicated RV. In such examples, the initial transmission (e.g., a dedicated RV) may begin at halfway point of the code (e.g., a non-starting position) (e.g., starting from a column other than the starting column of information column 225). In some examples, the new RV may begin with the first parity bit in the base graph or the lifting graph (e.g., the first parity bit included in the core parity column 230, or the first parity bit included in the extended parity column). The new RV may begin with a first degree-one extension (e.g., the first row in extended row 245). The new RV may begin with a second degree-one extension (e.g., in the case where the first degree-one extension is a special extension bit, which is the sum of two punched nodes).

[0089] For example, the initial core parity column 230 may be associated with an index 250 in the circular buffer 215 following the range 255 (e.g., such that the start bit of the encoded message is a parity bit, not a systematic bit). Index 250 may indicate a first non-systematic column (e.g., a column immediately following the last column in a set of information columns 225, associated with index value 21, such as the start column of core parity column 230 or the start column of extended parity column 235). Index 250 in the circular buffer 215 may be associated with a first degree-1 extension (e.g., a first extended row in extended row 245) that includes a special parity bit (e.g., a column associated with index value 25, where that column belongs to encoding matrix 210). Index 250 in the circular buffer 215 may be associated with a first degree-1 extension that excludes a special parity bit (e.g., a second extended row in extended row 245, where the first degree-1 extension corresponds to, for example, a column associated with index value 26). In some cases, the new RV is linked to a new data indicator (NDI) associated with the non-uniform message (e.g., because the parity of the initial transmission is sent, rather than the initial transmission).

[0090] In some examples, the new or special RV can be any RV different from the initial RV, or it may not include any system bits. For example, index 250-b may indicate a first column RV1 (e.g., the column associated with index value 16), which may include system bits (e.g., it may be one of the information columns in a set of information columns 225). However, since index 250-b is within range 255, at least a portion of RV1 may include system bits. Index 250-c may indicate the starting column of RV2 (e.g., the column associated with index value 32), which may fall outside range 255 (e.g., in this case, no bits in RV2 are system bits). Therefore, in some examples, RV2 may punch RV0 such that only parity bits are transmitted in the initial transmission (e.g., and only the parity bits corresponding to column 33 and subsequent columns are transmitted).

[0091] In some examples, a portion of the system bits and parity bits used to encode the initial message may be based on source entropy (e.g., entropy associated with one or more messages at the first device 205-a). If the source entropy is high, the first device may allow the transmission of a portion of the system bits. For example, the first device may transmit an initial transmission associated with RV1, which includes an index 250 associated with both the information column and the parity column. For example, when the source entropy is high (e.g., the initial message is uniform or nearly uniform), transmitting the parity bits (e.g., and without the system bits) may result in the transmission being undecodeable. For example, a threshold source entropy may exist (e.g., as referenced). Figure 1As described, above the source entropy threshold of H(p) = 0.7, non-systematic LDPCs will not be self-decoding. Instead, if the source entropy is high, the initial transmission may include some system bits and some parity bits (e.g., not all system bits can be punctured by the initial transmission).

[0092] Additionally or alternatively, the first device 205-a may transmit alternative instances of non-systematic LDPC for the message. For example, the first device 205-a may generate new parity. In some examples, the first device 205-a may encode the initial message based on a linear combination of the columns of the encoding matrix 210. In some examples, the first device may choose to display another instance of a non-systematic LDPC or LDGM subcode that has converged in the relevant source entropy region. In some examples, the first device 205-a may generate new codes or additional codes (e.g., new nodes in the encoding matrix 210), perform linear combinations of all columns (e.g., including additional codes), and select subcodes or any combinations to generate the encoded message partially or entirely based on the parity bits.

[0093] For transmissions with repetitions or HARQ retransmissions, the repetition or transmission may correspond to an RV sequence starting from a non-system RV (e.g., a repetition may start from RV2). After all parity bits are transmitted, the repetition may be rotated back to a system RV (e.g., RV0) according to the sequence in a later repetition. Additionally or alternatively, the first device 205-a may avoid using system bits for all repetitions or RVs according to the sequence. For example, system bits may be treated as punched bits for all RVs (e.g., and RV0 may not be transmitted at all or not included in the sequence at all). The RV sequence may be configured by the network (e.g., via control signaling received from the second device 205-b). In some examples, the RV sequence may be indicated for configuring permission to transmit or for transmissions with repetitions (e.g., via control signaling, such as a DCI message, that includes permission for such transmissions). If the indices 250 (e.g., positions) in the circular buffer are consecutive or contiguous, the second device 205-b may indicate a shift or the last index to the first device 205-a. For example, control signaling indicating an RV sequence may include indications of offsets or shifts (e.g., offsets in the number of columns such that the first column of the first RV does not include system bits), the last index (e.g., the final index included in the sequence), or combinations thereof.

[0094] In some examples, a subgroup of parity bits (e.g., a non-contiguous subgroup of parity bits in coding matrix 210) can be selected for transmission or a linear combination of parity bits. In some cases, the first device can selectively transmit parity bits connected to parity nodes with higher parity numbers. The first device 205-a can select higher parity numbers based on the fact that low parity does not produce a sufficiently uniform distribution on parity bits. In some cases, the first device can permutate the column order of coding matrix 210 such that parity nodes connected to parity nodes with higher parity numbers will appear first. In some cases, the first device can transmit a linear combination of parity bit subgroups. Different subcodes or subgraphs can be evaluated based on design criteria and the value of source entropy in the LDPC graph construction, thereby empirically finding the selected construction. In some cases, the selected construction may not be associated with parity nodes with higher parity numbers.

[0095] In some examples, such as reference Figures 3 to 5 and Figure 7 In more detail, the transmitting device (e.g., first device 205-a) can concatenate a first part (e.g., the LDGM part of the code) and a second part (e.g., the LDPC part of the code) of the same code. That is, the transmitting device can reuse the same code for both LDPC encoding and LDGM encoding. The two parts of the same code can be used as an inner code and an outer code (e.g., back-to-back encoding). The generation and use of parity bits for LDGM encoding can be based on one or more rules or on the techniques described herein (e.g., references...). Figure 2 )Execute autonomously.

[0096] Figure 3 An example of an encoding scheme 300 supporting code design for non-uniform sources, according to one or more aspects of this disclosure, is shown. The encoding scheme may be provided by a first device (e.g., as referenced). Figure 2 The first device 205-a) described herein is used to perform this operation. The code (e.g., LDPC code) may include a systematic bit 330, a core parity bit 335, zero-padding 340, an extension bit 345, and an extended parity bit 350. In some cases, the first set of columns 320-a may be used with the submatrix H. S Correspondingly, and the second group of columns 325-a can be related to submatrix P u Correspondingly, in some cases, the third column 320-b can be related to the submatrix H. s Correspondingly, and the fourth column 325-b can be associated with submatrix P u Correspondingly.

[0097] In some cases, to reduce the non-uniformity of encoded messages associated with non-uniform messages, the first device can perform two encoding processes on the non-uniform message using the same code (e.g., multiple parts of the same encoding matrix). Performing these two encoding processes creates a non-systematic LDPC encoding process. For example, the first device can concatenate the LDGM matrix associated with the LDPC code and the LDPC code. The first device can reuse the same code (e.g., NR code, etc.) for both the LDPC and LDGM encoding processes. That is, the first device can use two parts of the same encoding matrix for two encoding processes. The first encoding process can be an inner code, and the second encoding process can be an outer code. The first device can perform the first and second encoding processes back-to-back.

[0098] In some cases, the first encoding process may include LDPC codes, and the second encoding process may include the same LDPC code (e.g., as referenced). Figure 3 (Described in more detail). In some cases, the first device may use the same or different subcodes of the LDPC. In some cases, the first encoding process may include an LDGM associated with the LDPC code, and the second encoding process may include the LDPC code (e.g., as referenced). Figure 4 (Described in more detail). In other words, the first and second encoding processes can be associated with different portions of the encoding matrix corresponding to the same code. In some cases, the first encoding process may include an LDPC code, and the second encoding process may include an LDGM associated with the same LDPC code (e.g., as referenced). Figure 5 (Described in more detail). In some cases, the first or second encoding process may select a parity bit for the LDGM.

[0099] For example, Figure 3 Examples can be given of a first encoding process associated with an LDPC code and a second encoding process associated with the same LDPC code. The first device can encode message 305 (e.g., the message may be referred to as input) based on the corresponding portion of the LDPC code. s ) is encoded into a first encoded message 310 (for example, the first encoded message may be referred to as the output). u Message 305 may correspond to the first set of columns 320-a, and the first encoded message 310 may correspond to the second set of columns 325-a (e.g., The first device may encode the first encoded message 310 into a second encoded message 315 based on the corresponding part of the LDPC code (for example, the second encoded message may be referred to as output v, such that the transmission device transmits what is defined as...). (The transmission of the first encoded message 310 may correspond to the third group of columns 320-b, and the second encoded message 315 may correspond to the fourth group of columns 325-b (e.g., In some cases, the first group of columns 320-a and the third group of columns 320-b may be the same group of columns 320, and the second group of columns 325-a and the fourth group of columns 325-b may be the same group of columns 325. The first device may send a first encoded message 310 and a second encoded message 315 to the second device (e.g., may transmit...). In some cases, the second device may first decode the first encoded message 310, and then decode message 305. In some cases, the second device may use an equivalent parity check matrix to directly decode message 305.

[0100] In some cases, the LDPC subcode associated with the first encoding process and the LDPC subcode associated with the second encoding process can be the same LDPC subcode. In other cases, the LDPC subcode associated with the first encoding process and the LDPC subcode associated with the second encoding process can be different LDPC subcodes.

[0101] The receiving device can first from v right u Decode it, and then from u right s Decode it, or directly use an equivalent parity check matrix. s Decoding is performed to decode the message (e.g., it can be used to decode the message). s (For decoding). For example, such a parity check matrix may include two rows and three columns, with the first row containing data for... s The matrix (e.g., submatrix H) s ),against u The matrix (e.g., submatrix P) u ), and entry 0, the second line includes entry 0, targeting u The matrix (e.g., submatrix H) s ), and targeting v The matrix (e.g., submatrix P) u ).

[0102] Figure 4 An example of an encoding scheme 400 supporting code design for non-uniform sources, according to one or more aspects of this disclosure, is shown. The encoding scheme may be provided by a first device (e.g., as referenced). Figure 2 The first device 205-a) described herein is used to perform this operation. The LDPC code may include a systematic bit 440, a core parity bit 445, zero-filling 450, an extension bit 455, and an extended parity bit 460. In some cases, the first set of columns 420 may be associated with the submatrix H. S Correspondingly, and the second group of columns 425 can be related to submatrix P u Correspondingly, in some cases, the third column 430 can be associated with submatrix H.u Correspondingly, and the fourth column 435 can be associated with submatrix P v Correspondingly.

[0103] In some cases, the first device may encode the message according to a first encoding process associated with an LDGM related to an LDPC code and a second encoding process associated with the same LDPC code. The first device may encode message 405 (e.g., the message may be referred to as input) based on the corresponding portion of the LDGM. s ) is encoded into a first encoded message 410 (for example, this first encoded message may be referred to as the output). u Message 405 may correspond to the first set of columns 420, and the first encoded message 410 may correspond to the second set of columns 425 (e.g., In some cases, LDGM may be used as referenced. Figure 2 The special extended line described begins after this. The first device can encode the first encoded message 410 into a second encoded message 415 based on the corresponding part of the LDPC code (for example, this second encoded message can be referred to as output v, such that the transmitting device transmits what is defined as...). (Sending). The first encoded message 410 may correspond to the third group of columns 430, and the second encoded message 415 may correspond to the fourth group of columns 435 (e.g., The first device may send a first encoded message 410 and a second encoded message 415 to the second device. In some cases, the second device may first decode the first encoded message 410 and then decode message 405. In some cases, the second device may use an equivalent parity check matrix to directly decode message 405.

[0104] In other words, the receiving device can first obtain from v right u Decode it, and then from u right s Decode it, or directly use an equivalent parity check matrix. s Decoding is performed to decode the message (e.g., it can be used to decode the message). s (For decoding).

[0105] Figure 5 An example of an encoding scheme 500 supporting code design for non-uniform sources, according to one or more aspects of this disclosure, is shown. The encoding scheme may be provided by a first device (e.g., as referenced in the documentation). Figure 2 The first device 205-a) described herein is used to perform this operation. The LDPC code may include a systematic bit 540, a core parity bit 545, zero-filling 550, an extension bit 555, and an extended parity bit 560. In some cases, the first set of columns 520 may be associated with the submatrix H. S Correspondingly, and the second group of columns 525 can be related to submatrix P u Correspondingly, in some cases, the third column 530 can be associated with submatrix H. u Correspondingly, and the fourth column 535 can be associated with submatrix P v Correspondingly.

[0106] In some cases, the first device may encode the message according to a first encoding process associated with the LDPC code and a second encoding process associated with the LDGM matrix associated with the same LDPC code. The first device may encode message 505 (e.g., the message may be referred to as input) based on the corresponding portion of the LDPC code. s ) encoded into a first encoded message 510 (for example, the first encoded message may be referred to as the output) u Message 505 may correspond to the first set of columns 520, and the first encoded message 510 may correspond to the second set of columns 525 (e.g., The first device can encode the first encoded message 510 into a second encoded message 515 based on a corresponding portion of the LDGM matrix (e.g., the second encoded message may be referred to as the output). v This makes the transmission of the sending device defined as (Sending). The first encoded message 510 may correspond to the third group of columns 530, and the second encoded message 515 may correspond to the fourth group of columns 535 (e.g., In some cases, the LDGM matrix can be found in references. Figure 2 The special extended line described begins after this. The first device can send a first encoded message 410 and a second encoded message 515 to the second device (e.g., it can transmit...). In some cases, the second device may first decode the first encoded message 510, and then decode message 505. In some cases, the second device may use an equivalent parity check matrix to directly decode message 505.

[0108] Figure 6 An example of a process flow 600 supporting code design for non-uniform sources according to one or more aspects of this disclosure is shown. In some examples, process flow 600 may implement or be implemented by aspects of wireless communication system 100, wireless communication system 200, coding scheme 300, coding scheme 400, or coding scheme 500. For example, process flow 600 may include a first device 605-a and a second device 605-b, which may be reference devices. Figure 1 and Figure 5 Examples of the corresponding devices described.

[0109] At 610, the second device 605-b may send control signaling. Control signaling may include permission for resources to be transmitted (e.g., at 630). In some examples, control signaling indicates an initially transmitted RV sequence according to a circular buffer corresponding to the coding matrix. In some cases, the initial RV in the RV sequence may not include a set of information columns (e.g., it could be RV2, or a new RV or special RV that does not include any information columns or system bits). In some cases, a second RV in the RV sequence may include a set of information columns. A second RV may appear in the RV sequence after the first set of core parity columns and one or more sets of extended parity columns have been transmitted via the first RV and one or more additional RVs according to the circular buffer (e.g., an RV including system bits (such as RV0) may be included later or at the end of the RV sequence). In some cases, no RV in the RV sequence may include a set of information columns (e.g., the RV sequence does not include any RV containing system bits, such as RV0). In some cases, control signaling may include indications of offset values, indications of the index of the initial column of the encoded matrix relative to the circular buffer, indications of the final index of the first RV relative to the circular buffer, or any combination thereof.

[0110] At 615, the first device 605-a can generate an encoding matrix comprising: a set of information columns including system bits, a first set of core parity columns including a first set of parity bits, and one or more sets of extended parity columns including a second set of parity bits. In some cases, the initial columns of the encoding matrix may be associated with either the first set of parity bits or the second set of parity bits.

[0111] At 620, the first device 605-a may puncture one or more system bits in the system bits using a first set of parity bits, a second set of parity bits, or a combination thereof. Punching may be based on the offset value of the initial column of the coding matrix. In some cases, the offset value of the initial column of the coding matrix may be based on the entropy of the initial message exceeding an entropy threshold. The initial column may include, at least in part, one of the following based on the entropy of the initial message: an information column in a set of information columns, a core parity column in a first set of core parity columns, or an extended parity column in one or more sets of extended parity columns.

[0112] At position 625, the first device 605-a may encode the initial message according to the coding matrix based on the offset of the initial column of the instruction coding matrix. In some cases, the first device 605-a may select a first set of parity bits, a second set of parity bits, or a subgroup of parity bits of both.

[0113] In some cases, encoding may be based on a parity bit subgroup. The first device 605-a may select the parity bit subgroup based on: the degree of one or more parity nodes associated with the parity bit subgroup, the order of a set of information columns including system bits, the order of a first set of core parity columns including a first set of parity bits, the order of one or more sets of extended parity columns, or a candidate linear combination of parity bit subgroups, or any combination thereof.

[0114] At 630, the first device 605-a can transmit the encoded initial message. The encoded initial message may include the RV of the encoding matrix corresponding to the offset values ​​of the first set of parity bits or the second set of parity bits. The encoded initial message may not include system bits.

[0115] In some cases, the first device 605-a may initiate the transmission of the RV of the encoding matrix based on puncturing and encoding, wherein the initial bits of the RV include the first column of the first set of core parity columns. In some cases, the first device 605-a may initiate the transmission of the RV of the encoding matrix based on puncturing and encoding, wherein the initial bits of the RV include a first occurrence degree-extended parity bit of either the first set of parity bits or the second set of parity bits. The first occurrence degree-extended parity bit may include a special extended parity bit that connects the initial bits of the RV to the punctured system bits. In some cases, the first device 605-a may initiate the transmission of the RV of the encoding matrix based on puncturing and encoding, wherein the initial bits of the RV include a second occurrence degree-extended parity bit of either the first set of parity bits or the second set of parity bits. In some cases, the first RV in a set of RVs of the encoding matrix may correspond to a set of information columns. The RV of the encoding matrix may include a second RV in a set of RVs that does not include a set of information columns.

In some examples, process flow 700 may implement or be implemented by aspects of wireless communication system 100, wireless communication system 200, coding scheme 300, coding scheme 400, coding scheme 500, or process flow 600. For example, process flow 700 may include a first device 705-a and a second device 705-b, which may be reference devices. Figure 1 and Figure 6 Examples of the corresponding devices described.

[0117] At 710, the first device 705-a can generate an encoding matrix including: a set of information columns including system bits, a first set of core parity columns including a first set of parity bits, and a set or more sets of extended parity columns including a second set of parity bits.

[0118] At 715, the first device 705-a can perform a first encoding process according to the first part of the encoding matrix.

[0119] At 720, the first device 705-a can perform a second encoding process on the output of the first encoding process according to the second part of the encoding matrix.

[0120] At 725, the first device 705-a can send the encoded message based on the output of the first encoding process and the output of the second encoding process.

[0121] In some cases, the first encoding process may include LDPC corresponding to the first systematic bit and the first set of parity bits, and the second encoding process may include LDPC corresponding to the first systematic bit and the first set of parity bits, as shown in the reference. Figure 3 As described. In some cases, the first encoding process may include an LDGM corresponding to the second set of parity bits, and the second encoding process may include an LDPC corresponding to the first system bits and the first set of parity bits, as described in the reference. Figure 4 As described. In some cases, the first encoding process may include LDPC corresponding to the first system bits and the first set of parity bits, and the second encoding process may include LDGM corresponding to the second set of parity bits.

A general-purpose processor may be a microprocessor, but in alternatives, a processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors combined with a DSP core, or any other such configuration). Any function or operation described herein that can be performed by a processor may be performed by multiple processors capable of performing the described function or operation individually or jointly.

[0215] The functions described herein can be implemented using hardware, software executed by a processor, firmware, or any combination thereof. When implemented using software executed by a processor, the functions can be stored as one or more instructions or code on a computer-readable medium or transmitted using one or more instructions or code on a computer-readable medium. Other examples and specific implementations are within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functions described herein can be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination of these. Features implementing the functions can also be physically located in various locations, including portions distributed such that the functions are implemented in different physical locations.

[0216] Computer-readable media includes both non-transitory computer storage media and communication media, encompassing any medium that facilitates the transfer of a computer program from one location to another. Non-transitory storage media can be any available medium accessible by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compressed optical disc (CD) ROM or other optical disc storage devices, magnetic disk storage devices or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store desired program code components in the form of instructions or data structures, and accessible by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor.

[0217] As used herein, the word "or" in a list of items (e.g., a list of items accompanied by phrases such as "at least one of" or "one or more of") in the claims indicates an inclusive list, such that a list of at least one of, for example, A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Furthermore, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an example step described as "based on condition A" could be based on both condition A and condition B without departing from the scope of this disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on".

[0218] As used herein, including in claims, the article “a” preceding a noun is open-ended and is understood to refer to “at least one” or “one or more” of those nouns. Therefore, the terms “a,” “at least one,” “one or more,” and “at least one of one or more” are interchangeable. For example, where a claim enumerates “components” performing one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “component” having a characteristic or performing a function may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent references to a component introduced with the article “a” using the terms “the” or “the” can refer to any or all of the one or more components. For example, a component introduced with the article “a” can be understood to mean “one or more components,” and subsequent reference to “the component” in a claim can be understood as equivalent to referring to “at least one of the one or more components.” Similarly, subsequent references to a component introduced with the terms “the” or “the” as “one or more components” can refer to any or all of the one or more components. For example, reference to "the one or more components" in the subsequent claims can be understood as equivalent to reference to "at least one of the one or more components".

[0219] The term "determine" encompasses a variety of actions, and therefore, "determine" can include calculation, computation, processing, derivation, investigation, searching (such as by searching in a table, database, or other data structure), ascertainment, etc. Furthermore, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory), etc. Moreover, "determine" can include parsing, obtaining, selecting, choosing, creating, and other similar actions.

[0220] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type can be distinguished by adding a dash after the reference numeral and a second reference numeral to differentiate between similar components. If only the first reference numeral is used in the description, the description applies to any of the similar components having the same first reference numeral, regardless of the second reference numeral or other subsequent reference numerals.

[0221] The description herein, illustrated with reference to the accompanying drawings, describes an example configuration and does not represent all achievable examples or those within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration," not "preferred" or "advantageous over other examples." The detailed description includes specific details used to provide an understanding of the described techniques. However, these techniques can be practiced without these specific details. In some of the drawings, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.

[0222] The description herein is provided to enable those skilled in the art to implement or use this disclosure. Various modifications to this disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the examples and designs described herein, but should be granted the widest scope consistent with the principles and novel features disclosed herein.
