[0002] This patent application claims priority to Israel Patent Application No. 305940, filed on September 13, 2023, entitled “MULTIPLE PARITY BIT MAPPINGSCHEMES FOR A COMMUNICATION”, which is assigned to the assignee of this application. The disclosure of the earlier application is considered part of this patent application and is incorporated herein by reference. Background Technology

[0003] All aspects of this disclosure relate to wireless communication, and to techniques and apparatus for communicating using parity bits.

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. UEs may communicate with network nodes via downlink and uplink communication. A "downlink" (or "DL") refers to the communication link from the network node to the UE, and an "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via local links (e.g., sidelinks (SL), wireless local area network (WLAN) links, and / or wireless personal area network (WPAN) links).

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband internet access by: improving spectrum efficiency; reducing costs; improving service; utilizing new spectrum; and better integrating with other open standards by using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), and CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink; and supporting beamforming, Multiple-Input Multiple-Output (MIMO) antenna technologies and carrier aggregation. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to increase. Summary of the Invention

[0036] In some networks, wireless communication devices (WCDs) can communicate using frequency ranges above 20 GHz, such as those using sub-THz bands (e.g., between approximately 90 GHz and 300 GHz). High-frequency ranges (such as sub-THz bands) can at least partially support increased throughput due to the relatively large available bandwidth. For example, increased throughput could include throughput links, such as 300 gigabits per second (Gbps) links.

[0037] To enable communication over high frequencies, as described, the WCD can utilize low-complexity decoders (e.g., those associated with power consumption and / or decoding latency that meet thresholds), such as Bosch-Chowdhury-Hokungamme (BCH) decoders or Reed-Solomon (RS) decoders. Additionally, increasing the decoding rate (e.g., by reducing the amount of data carried on the set of communication resources) can be used to reduce decoder complexity. High decoding rates can be achieved using product code encoding schemes that can include decoding communication in both a first dimension and a second direction. For example, a product code encoding scheme can use multiple BCH codes or RS codes with different code rates, which are combined to form the total code rate.

[0038] On some channels, the received WCD can detect a channel response with a peak-to-peak difference of several decibels (dB). For example, the received signal strength of a first set of frequency ranges may be within a first dB range, and the received signal strength of a second set of frequency ranges may be within a second dB range below the first dB range. This may occur based on interference, noise, and / or propagation effects, which may differ in the channel at least in part because the channel is wider than a lower frequency channel (such as frequency range (FR) 1 or FR 2 (described below)).

[0039] In some networks, a decoding configuration can be selected to accommodate a second dB range. Consequently, the decoding rate can be high enough to decode the second set of frequency ranges, and may be higher than the decoding rate required to decode the first set of frequency ranges. This may unnecessarily reduce the throughput of information transmitted via the first set of frequency ranges. Alternatively, a decoding configuration can be selected to maximize the throughput of the first set of frequency ranges, which may result in a decoding rate too low to decode the second set of frequency ranges. Consequently, the bit error rate associated with the second set of frequency ranges may cause decoding failures, and correcting these failures may consume power, computation, communication, and / or network resources (e.g., via requests and retransmissions).

[0040] Various aspects relate to a communication having different parity bit mapping schemes applied to different frequency ranges of the communication. In some examples, the transmitting device may apply different parity bit mapping schemes to different sub-channels of the communication. In some aspects, a first parity bit mapping scheme (e.g., having a relatively high number of parity bits) may be applied to a first set of one or more sub-channels with relatively low received power, and a second parity bit mapping scheme (e.g., having a relatively high number of parity bits) may be applied to a second set of one or more sub-channels with relatively high received power.

[0041] In some aspects, the first parity bit mapping scheme is associated with a first number of dimensions having parity bits, and the second parity bit mapping scheme is associated with a second number of dimensions having parity bits and / or having parity bits regenerated into parity bits. Thus, the received WCD can apply decoding using parity bits in the first number of dimensions for a first set of one or more sub-channels, and can apply decoding using parity bits in the second number of dimensions and / or parity bits regenerated into parity bits for a second set of one or more sub-channels.

[0042] Parity bits can be used to create a sum of system bits and parity bits, which is then applied using a modulo function to match a configuration value of 1 or 0, as sent from the transmitting WCD. For example, the sum of system bits can be even (e.g., modulus 0). If the parity configuration value is 0, the sum of parity bits (e.g., bits associated with the constellation point to which the parity signal is mapped) can also be even to provide a sum of system bits and parity bits 410 with a modulus of 0. If the receiving WCD decodes the system bits and parity bits and finds a modulus of 1, the receiving WCD can perform additional decoding operations to find errors that prevent the modulus from matching the configuration value of 0. In some respects, using parity bits in only one dimension may offer minimal help in error correction but could include higher density data bits.

[0043] In a parity bit mapping scheme that includes parity bits for two decoding dimensions (e.g., rows and columns), communication can be organized using bit values ​​arranged in rows and columns. Parity bits used for decoding in the first dimension (e.g., rows) may include one or more bits to check parity in the first dimension (e.g., for each row), so the received WCD can identify a subset of erroneous system bits (e.g., a row), rather than simply identifying the presence of errors across the entire set of system bits. This improves error correction by reducing the decoding resources for potential errors. In addition to decoding each row in the row, the received WCD can also decode columns of system bits and check parity using a set of parity bits configured to check parity in the second dimension. This allows the received WCD to more easily locate system bit errors relative to a single encoding dimension (e.g., by isolating a subset of system bits in the row associated with an error detected by the parity bits). Additionally or alternatively, using two encoding dimensions, errors from the first row and errors from the second row may not cancel each other out and become undetectable by the decoder.

[0044] In some respects, the same decoder (e.g., a BCH and / or RS decoder) can be applied to decode bits in the first dimension (e.g., rows) and / or the second dimension (e.g., columns). Thus, a single decoder can be used to decode each subchannel in which different parity bit mapping schemes are applied (e.g., different code rates, but in different numbers of dimensions. For example, the receive WCD can apply a single decoder to each subchannel in rows only, columns only, rows and columns of system bits, or rows and columns of system bits and rows or columns of parity bits).

[0045] Specific aspects of the subject matter described in this disclosure can be implemented to save computational, power, network, and / or communication resources. In some examples, by using different parity bit mapping schemes for different parts of the communication, the communication can reduce decoding errors (e.g., compared to a single parity bit mapping scheme with too few parity bits), reduce unnecessary overhead (e.g., compared to a single parity bit mapping scheme with too many parity bits), and / or save power and / or computational resources that might otherwise be used to decode the communication using different rate-matching configurations.

[0046] In some aspects, the network node may send to the UE indications of the assignment of a first parity bit mapping scheme and a second parity bit mapping scheme (e.g., to one or more sub-channels of communication). For example, the network node may indicate that a first set of sub-channels is assigned to the first parity bit mapping scheme, and a second set of sub-channels is assigned to the second parity bit mapping scheme. Additionally or alternatively, the network node may send indications of one or more parameters for the UE to identify the assignment. For example, the network node may send indications of one or more channel energy thresholds, one or more capacity thresholds, and / or one or more signal-to-noise ratio (SNR) thresholds that the UE can use to identify the parity bit mapping scheme assigned to the sub-channels. Thus, the UE and the network node can synchronize the mapping of the communication sub-channels to different parity bit mapping schemes. This allows the UE and the network node to use multiple schemes to improve the spectral efficiency of communication.

[0047] In some aspects, upon connection establishment, the UE may report (e.g., for a single communication with frequency resource allocation) the ability to support configurable decoding per allocation (e.g., associated with the number of parity bits and / or parity bit mapping scheme, etc.). In some aspects, the UE may report the decoding options supported by the UE, such as without product code, with product code, with product code and parity bit regeneration, or any other configuration that changes the decoding rate and allows the basic BCH decoding unit to be used for different decoding options. In some aspects, the UE may report the desired gap between each configuration. In some aspects, the UE may indicate the desired gap by rank, by modulation and decoding scheme (MCS), and / or at least in part based on other parameters of the communication.

[0048] Once the UE is in connected mode, network nodes can transmit indications of different decoding rates, such as bit vectors representing the code rate of each resource element, resource block, subband, code block, and / or code block group. In some aspects, this vector can be compressed, for example, by differentially analyzing adjacent values. In some aspects, adjacent sub-channels can be highly correlated and have the same code rate, at least in part based on coherence bandwidth. This can produce a differential vector that is mostly zero, which can be efficiently compressed using models such as Huffman compression. In some aspects, the report can use differentials relative to the previous report, which reduces non-zero values ​​and achieves further compression.

[0049] Additionally or alternatively, the network node may send to the UE an indication (e.g., a report) of thresholds associated with channel energy, SNR values, and / or capacity. The UE may identify the code rate, the number of parity bits, and / or the parity bit mapping scheme based at least in part on these thresholds and measurements of communication at the sub-channel. In some aspects, multiple thresholds may be used to define a range of values, wherein if a measurement falls within this range, the UE maps the sub-channel to an associated code rate, the number of parity bits, and / or the parity bit mapping scheme, etc. In some aspects, the measurement may be based at least in part on sounding reference signal (SRS) channel estimation and reciprocity assumptions, or at least in part on UE channel state information (CSI) reports (e.g., channel state feedback (CSF) of the channel) or an indication of the expected code rate per allocation (e.g., at least in part based on the measurement expectation).

[0050] Network nodes may send indications of thresholds via Radio Resource Control (RRC) messages, Medium Access Control (MAC) control elements (CE), and / or Downlink Control Information (DCI) (e.g., associated with Doppler spread), and / or these may be periodic or aperiodic. In some aspects, the UE may report if the configuration is ineffective for decoding communications from the UE. In some aspects, the UE may provide fine-grained feedback (e.g., indicating invalid portions of the configuration) based at least in part on, for example, collecting statistics on the number of iterations for each subband and whether decoding succeeded.

[0051] Although described in the context of transmission from the network node to the UE, the WCD may include an Integrated Access and Backhaul (IAB) node. Additionally or alternatively, communication may be uplink communication from the UE (e.g., an encoded WCD) to the network node (e.g., a decoded WCD using a single decoder).

[0052] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of protection of this disclosure to those skilled in the art. Those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods implemented using structures, functions, or structures and functions other than or different from the aspects of the disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of these claims.

[0053] Various devices and techniques will now be used to illustrate several aspects of a telecommunications system. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0054] Although terms generally associated with 5G or New Radio (NR) Radio Access Technology (RAT) may be used herein to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or 5G and later (e.g., 6G) RATs.

[0055] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., LTE) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. Network node 110 is a network node that communicates with UE 120. As shown, network node 110 may include one or more network nodes. For example, network node 110 can be an aggregated network node, meaning that an aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0056] In some examples, network node 110 is or includes network nodes (such as RUs) that communicate with UE 120 via a radio access link. In some examples, network node 110 is or includes network nodes (such as DUs) that communicate with other network nodes 110 via a fronthaul or midhaul link. In some examples, network node 110 is or includes network nodes (such as CUs) that communicate with other network nodes 110 via a midhaul link or with the core network via a backhaul link. In some examples, network node 110 (such as aggregated network node 110 or decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. Network node 110 may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, Transmit / Receive Points (TRPs), DUs, RUs, CUs, network mobility elements, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some examples, network nodes 110 can interconnect with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network through various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks).

[0057] In some examples, network node 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term is used, the term "cell" may refer to the coverage area of ​​network node 110 and / or the network node subsystem serving that coverage area. Network node 110 may provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A picocell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UE 120 associated with the femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Network node 110 used for macrocells may be referred to as a macro network node. Network node 110 used for picocells may be referred to as a pico network node. The network node 110 used for femtocells can be referred to as a femtocell network node or a home network node. Figure 1In the example shown, network node 110a can be a macro network node for macro cell 102a, network node 110b can be a pico network node for pico cell 102b, and network node 110c can be a femto network node for femto cell 102c. Network nodes can support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographical area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0058] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an IAB node, a relay node, or one or more components thereof. For example, in some aspects, "base station" or "network node" may refer to a CU, DU, RU, near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of that function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some respects, the term "base station" or "network node" can refer to one base station function within a base station system, rather than another. Therefore, a single device can include more than one base station.

[0059] Wireless network 100 may include one or more relay stations. A relay station is a network node that can receive data transmissions from upstream nodes (e.g., network node 110 or UE 120) and transmit data to downstream nodes (e.g., UE 120 or network node 110). A relay station may be a UE 120 that can relay transmissions for other UE 120s. Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. The network node 110 for relay communication may be referred to as a relay station, relay base station, relay network node, relay node, repeater, etc.

[0060] Wireless network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different effects on interference in wireless network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0061] Network controller 130 may be coupled to or communicate with a group of network nodes 110, and may provide coordination and control for these network nodes 110. Network controller 130 may communicate with network nodes 110 via a backhaul or midhaul link. Network nodes 110 may also communicate directly with each other, or indirectly via a wireless or wired backhaul link. In some aspects, network controller 130 may be a CU or a core network device, or may include a CU or a core network device.

[0062] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, a UE function of a network node, and / or any other suitable device configured to communicate via wireless or wired media.

[0063] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, unmanned aerial vehicles, remote devices, sensors, instruments, monitors, and / or location tags that can communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UEs 120 may be included within a housing that houses the components of the UE 120, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0064] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT may be referred to as a radio technology, air interface, etc. A frequency may be referred to as a carrier, frequency channel, etc. Each frequency in a given geographical area can support a single RAT to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0065] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary device to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols) and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0066] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., by frequency / wavelength. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, in various documents and articles, FR1 is often (interchangeably) referred to as the "sub-6GHz" band. Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although this is different from the Extremely High Frequency (EHF) band (30GHz to 300GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU).

[0067] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have identified the operating bands used for these mid-band frequencies as the frequency range designation FR3 (7.125 GHz to 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating frequency bands have been identified as the frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0068] Considering the examples above, unless otherwise specifically stated, it should be understood that when the term "below 6 GHz" is used herein, it can broadly refer to frequencies below 6 GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that when the term "millimeter wave" is used herein, it can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. Modifications to frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) are contemplated, and the techniques described herein are applicable to those modified frequency ranges.

[0069] In some aspects, the WCD (e.g., a UE, a network node, or another node such as an IAB node) may include a communication manager 140 or 150. As described in more detail elsewhere herein, the communication manager 140 or 150 may send instructions for supporting multiple parity bit mapping schemes for communication; and receive communication having a first parity bit mapping scheme and a second parity bit mapping scheme, the first parity bit mapping scheme being different from the second parity bit mapping scheme. As described in more detail elsewhere herein, the communication manager 140 or 150 may receive instructions for supporting multiple parity bit mapping schemes for communication; and send communication having a first parity bit mapping scheme and a second parity bit mapping scheme, the first parity bit mapping scheme being different from the second parity bit mapping scheme. Additionally or alternatively, the communication manager 140 or 150 may perform one or more other operations described herein.

[0070] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0071] Figure 2 This is a diagram illustrating example 200 of communication between network node 110 and UE 120 in a wireless network 100 according to this disclosure. Network node 110 may be equipped with a set of antennas 234a to 234t, such as... T One antenna ( T ≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R One antenna ( R ≥1). Network node 110 of Example 200 includes one or more radio frequency components, such as antenna 234 and modem 232. In some examples, network node 110 may include an interface, communication components, or another component that facilitates communication with UE 120 or another network node. Some network node 110 may not include radio frequency components that facilitate direct communication with UE 120, such as one or more CUs or one or more DUs.

[0072] At network node 110, transmitting processor 220 can receive data from data source 212 intended for use by UE 120 (or a group of UEs 120). Transmitting processor 220 can select one or more modulation and decoding schemes (MCS) for UE 120, at least in part, based on one or more Channel Quality Indicators (CQIs) received from UE 120. Network node 110 can process (e.g., encode and modulate) the data for UE 120, at least in part, based on the MCS selected for UE 120, and can provide data symbols for UE 120. Transmitting processor 220 can process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can transmit a set of output symbol streams (e.g., T Each output symbol stream is provided to a corresponding set of modems 232 (e.g., ...). T Each modem 232a to 232t can be used to process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. For example, each output symbol stream can be provided to a modulator component (MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use a corresponding modulator component to process the output sample stream (e.g., convert to analog, amplify, filter, and / or up-convert) to obtain a downlink signal. Modems 232a to 232t can be connected via a corresponding set of antennas 234 (e.g., T Each antenna (shown as antennas 234a to 234t) is used to transmit a set of downlink signals (e.g., ...). T (One downlink signal).

[0073] At UE 120, a set of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from network node 110 and / or other network nodes 110 and can transmit a set of received signals (e.g., R The received signals are provided to a group of modems 254 (e.g., REach modem 254 (shown as modems 254a to 254r) may receive a signal. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, down-convert, and / or digitize) the received signal to obtain an input sample. Each modem 254 may use a demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 may obtain the received symbols from modem 254, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. Receiver processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine parameters such as the Reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), and / or CQI. In some examples, one or more components of the UE 120 may be included in a housing.

[0074] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, for example, in a core network. Network controller 130 may communicate with network node 110 via communication unit 294.

[0075] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements and / or one or more antenna arrays, etc., or may be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements and / or be coupled to one or more transmitting and / or receiving components (such as, Figure 2 One or more antenna elements (one or more components in a )

[0076] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 can be pre-decoded by the TX MIMO processor 266 where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some examples, the modem 254 of UE 120 may include a modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein.

[0077] At network node 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232 (shown as DEMOD)), detected by MIMO detector 236 (where applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of network node 110 may include modulator and demodulator. In some examples, network node 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220 and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein.

[0078] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120 and / or Figure 2Any other component may perform one or more techniques associated with communication using multiple parity bit mapping schemes for communication, as described in more detail elsewhere herein. In some aspects, the WCD described herein is network node 110, included in network node 110, or includes Figure 2 One or more components of the network node 110 shown. In some respects, the WCD described herein is UE 120, included in UE 120, or comprising Figure 2 One or more components of the UE 120 shown.

[0079] For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component that can execute or direct, for example Figure 7 The process 700 Figure 8 The operation of process 800 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions may cause one or more processors, UE 120 and / or network node 110 to perform or direct, for example, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly executed, or executed after compilation, transformation and / or interpretation). Figure 7 The process 700 Figure 8 The operation of process 800 and / or other processes as described herein. In some examples, the execution instructions may include run instructions, transformation instructions, compilation instructions, and / or interpretation instructions, etc.

[0080] In some aspects, the WCD (e.g., UE 120 or network node 110) includes components for transmitting indications of supporting multiple parity bit mapping schemes for communication; and / or components for receiving communication having a first parity bit mapping scheme and a second parity bit mapping scheme, the first parity bit mapping scheme being different from the second parity bit mapping scheme. In some aspects, components for the wireless communication device (WCD) to perform the operations described herein may include, for example, one or more of a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246. In some aspects, components for a wireless communication device (WCD) to perform the operations described herein may include, for example, one or more of a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0081] In some aspects, the WCD (e.g., network node 110 or UE 120) includes components for receiving indications of multiple parity bit mapping schemes supporting communication; and / or components for transmitting communication having a first parity bit mapping scheme and a second parity bit mapping scheme, the first parity bit mapping scheme being different from the second parity bit mapping scheme. In some aspects, components for the wireless communication device (WCD) to perform the operations described herein may include, for example, one or more of a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246. In some aspects, components for a wireless communication device (WCD) to perform the operations described herein may include, for example, one or more of a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0082] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0083] In some respects, individual processors may be described as performing all functions executed by the one or more processors. In other respects, the one or more processors may jointly perform a set of functions. For example, the processors of a first set (one or more) of the one or more processors may be described as performing a first function executed by the one or more processors, and the processors of a second set (one or more) of the one or more processors may be described as performing a second function executed by the one or more processors. The processors of the first set and the processors of the second set may be processors of the same set or processors of different sets. The reference to "one or more processors" should be understood as referring to a combination. Figure 2 Any one or more processors described. The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as those in conjunction with... Figure 2 The memory described. For example, a function described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0084] As indicated above, Figure 2 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 2 The examples described are different.

[0085] Communication systems (such as 5G NR systems) can be deployed in various ways with a variety of components or parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in a converged or decomposed architecture. For example, a base station (such as a Node B (NB), evolved NB (eNB), NR base station, 5G NB, access point (AP), TRP, or cell, etc.) or one or more units (or one or more components) that perform base station functions can be implemented as a converged base station (also known as a standalone base station or monolithic base station) or a decomposed base station. A "network entity" or "network node" can refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or combinations thereof).

[0086] Aggregated base stations (e.g., aggregated network nodes) can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or cell). Decomposed base stations (e.g., decomposed network nodes) can be configured to utilize a protocol stack that is physically or logically distributed across two or more cells (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual cell, such as a Virtual Central Unit (VCU), a Virtual Distributed Unit (VDU), or a Virtual Radio Unit (VRU), etc.

[0087] Base station type operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in IAB networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)) to facilitate the scaling of communication systems by separating base station functionality into one or more units that can be deployed independently. Decomposed base stations can include functionality implemented across two or more units at various physical locations, as well as functionality virtually implemented for at least one unit, which enables flexibility in network design. Each unit of a decomposed base station can be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0088] Figure 3 This is an illustration of an example disaggregated base station architecture 300 according to this disclosure. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more disaggregated control units (such as near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a Service Management and Orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RUs 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UEs 120 via a corresponding radio frequency (RF) access link. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0089] Each unit in the cells (including CU 310, DU 330, RU 340), as well as the near-RT RIC 325, non-RT RIC 315, and SMO frame 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the cell, or an associated processor or controller providing instructions to one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more units in other cells via transmission media. In some examples, each unit in the cell may include a wired interface and a wireless interface configured to receive signals or transmit signals to one or more units in other cells via a wired transmission media, and the wireless interface may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals or transmit signals to one or more units in other cells via a wireless transmission media, or both.

[0090] In some aspects, the CU 310 can host one or more higher-level control functions. Such control functions may include RRC functions, Packet Data Convergence Protocol (PDCP) functions, or Service Data Adaptation Protocol (SDAP) functions, etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP) functions), control plane functions (e.g., Central Unit-Control Plane (CU-CP) functions), or combinations thereof. In some implementations, the CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be implemented to communicate with the DU330 for network control and signaling purposes, as needed.

[0091] Each DU 330 may correspond to a logical unit comprising one or more base station functions for controlling the operation of one or more RU 340s. In some aspects, the DU 330 may host one or more of the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and one or more high physical (PHY) layers, at least in part, according to functional splits (such as those defined by 3GPP). In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation. In some aspects, the DU 330 may also host one or more low PHY layers, such as those implemented by one or more modules for Fast Fourier Transform (FFT), Inverse FFT (iFFT), Digital Beamforming, or Physical Random Access Channel (PRACH) extraction and filtering. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0092] Each RU 340 can implement lower-layer functionality. In some deployments, an RU 340 controlled by a DU 330 can correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, based on function splitting (e.g., function splitting defined by 3GPP) (such as lower-layer function splitting). In such architectures, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, the real-time and non-real-time aspects of communication with the control plane and user plane of the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration allows each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0093] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 305 can be configured to interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTTRIC 325. In some specific implementations, the SMO framework 305 may communicate with 4G RAN hardware aspects such as the Open eNB (O-eNB) 311 via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0094] The non-RT RIC 315 can be configured to include logical functions that enable non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325, such as via an A1 interface. The near-RT RIC 325 can be configured to include logical functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as an E2 interface, through data collection and actions, connecting one or more CU 310s, one or more DU 330s, or both, and O-eNBs to the near-RT RIC 325.

[0095] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the SMO framework 305 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0096] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The examples described are different.

[0097] Figures 4A to 4C These are illustrations of examples 400, 415, 435, and 460 illustrating different decoding operations according to this disclosure. In example 400, BCH decoding, RS decoding, or another decoding scheme may be applied to wireless communication with one-dimensional coding. In some examples, the coding may include a ladder coding scheme, where the encoder starts with an initial value and adds subsequent data points based at least in part on the difference between subsequent data points and previous data points in the communication. These differences may be quantized into discrete intervals, which may be encoded into bits (e.g., a binary representation of these differences).

[0098] Example 415 illustrates a product decoding scheme that includes the application of encoding in two dimensions (e.g., encoding using a first set of parity bits in the first dimension and encoding using a second set of bits in the second dimension). Example 435 illustrates a product decoding scheme that includes the application of encoding in two dimensions and has parity bit regeneration (e.g., at least one set of parity bits has parity bits in that set for detecting errors in the system bits). Example 460 illustrates a product decoding scheme that includes the application of encoding in three dimensions, and may also include parity bit regeneration. Figures 4A to 4D In each of these, the dashed arrows show how the system bits are mapped to parity bits (where the mapped parity bits are used to check the parity of the associated system bits). Different styles of dashed lines show system bits grouped into different dimensions for parity checking using parity bits.

[0099] like Figure 4AAs shown, and in Example 400, communication (e.g., from a transmitting WCD to a receiving WCD) may include system bits 405 (e.g., information from the transmitting WCD to the receiving WCD), which include the payload of the communication. The payload may include a series of information bits, and parity bits may be used to check for correct decoding. For example, the receiving WCD may map a signal (e.g., within a resource element) to a constellation point of the modulation and decoding scheme (MCS) associated with the communication. When mapping a signal to a constellation point, the receiving WCD may map the signal to the nearest constellation point (e.g., in the in-phase and quadrature (IQ) plane). Constellation points may be associated with a set of bits.

[0100] Once the decoder generates a sequence of bits (system bit 405) from the constellation points of the communicating signal, it can use parity bit 410 to check for errors. For example, the parity bit can be used to create a sum of system bit 405 and parity bit 410, and then a modulo function is applied to match it with a configuration value of 1 or 0, as sent from the transmitting WCD. In a particular example, the sum of system bits 405 can be even (e.g., modulus 0). If the parity configuration value is 0, the sum of parity bits 425 (e.g., bits associated with the constellation points to which the parity signal is mapped) can also be even to provide a sum of system bits 405 and parity bit 410 with a modulus of 0. If the receiving WCD decodes system bits 405 and parity bit 410 and finds a modulus of 1, the receiving WCD can perform additional decoding operations to find errors that prevent the modulus from matching the configuration value of 0.

[0101] In high SNR scenarios, it may be appropriate to perform decoding using parity bits (e.g., in BCH or RS codes) on a single dimension (as in Example 400). However, in low SNR scenarios, adding coding gain can improve decoding accuracy.

[0102] like Figure 4B As shown, and by way of example 415, communication may include system bits 420 organized into two dimensions. Thus, parity bits 425 may include subsets of parity bits, each subset associated with a different row of system bits 420. This allows the received WCD to more easily locate errors in system bits relative to a single coding dimension (e.g., by isolating subsets of system bits in rows associated with errors detected by parity bits). Additionally or alternatively, using two coding dimensions, errors from the first row and errors from the second row may not cancel each other out and become undetectable by the decoder.

[0103] In some examples, communication may consist only of system bit 420 and parity bit 425. In other examples, communication may also include parity bit 430, configured to check for errors in the column of system bit 420. Thus, compared to having only parity bit 425, the decoder can find errors with improved accuracy by identifying the row and column positions of the errors. Additionally or alternatively, the decoder may further reduce the number of errors that are not detected due to their canceling out and becoming transparent on a row bit. For example, if system bit 420 includes an erroneous system bit 420A (including one or more bits), parity bit 425A may indicate an error on the row associated with the erroneous system bit 420A. Additionally or alternatively, parity bit 430A may indicate an error on the column associated with the erroneous system bit 420A. Thus, the received WCD can identify the location of the erroneous system bit 420A.

[0104] Thus, compared to having only parity bit 425, the decoder can find errors with improved accuracy by identifying the row and column positions of the errors. Additionally or alternatively, the decoder can further reduce the number of undetected errors associated with error bits canceling each other out and becoming transparent on a row. In some examples, communication may consist only of system bit 420, parity bit 425, and parity bit 430.

[0105] like Figure 4C As shown, and through Example 435, communication may include a system bit 440 organized into two dimensions, parity bits 445 comprising a subset of parity bits associated with different rows of system bit 440, and parity bits 450 comprising a subset of parity bits associated with different columns of system bit 440, as shown in Example 415. In Example 435, communication also includes parity bit regeneration of parity bit 455 configured to check for errors in parity bits 450 and / or parity bits 445. Thus, parity bits 445 and / or 450 may have improved accuracy, which in turn improves the decoding of system bit 440 using parity bits 445 and / or 450. For example, if system bit 440 includes an erroneous system bit 440A (comprising one or more bits), then parity bit 445A may indicate an error on the row associated with the erroneous system bit 440A. Alternatively, parity bit 450A may indicate an error on the column associated with the erroneous system bit 440A. Thus, the received WCD can identify the location of the erroneous system bit 440A.

[0106] like Figure 4DAs shown, and through Example 460, communication can include a 3D or more dimensional encoding / decoding scheme. As illustrated, communication can be organized into three dimensions (e.g., width, length, and depth). Thus, the system bit 465 can be checked in all three dimensions to identify decoding errors. For example, parity bit 470 can include a first subset 475 of parity bits, where each subset of the first subset 475 is associated with a different subset of system bits 445 in the first dimension; it can include a second subset 480 of parity bits, where each subset of the second subset 480 is associated with a different subset of system bits in the second dimension; and it can include a third subset 485 of parity bits, where each subset of the third subset 485 is associated with a different subset of system bits in the third dimension. This allows the received WCD to more easily locate errors in system bits relative to one or two encoding dimensions. This can support error correction when a relatively high number of decoding errors is expected (e.g., in low SNR scenarios).

[0107] In some examples, the communication may consist only of parity bit 450 associated with system bit 445. In other examples, the communication may also include parity bit regeneration, as described in conjunction with example 420. In some examples, parity bit regeneration may include parity bit regeneration in only one dimension, in two dimensions, or in three dimensions, etc.

[0108] As indicated above, Figures 4A to 4C This is provided as an example. Other examples are available with reference to [the relevant information]. Figures 4A to 4C The examples described are different.

[0109] like Figures 4A to 4C As shown and otherwise described herein, product codes are iterative codes that improve the decoding gain of non-iterative codes such as BCH codes or Reed-Solomon codes. In product code encoding schemes, the transmitted WCD arranges the data in a square order of bits (e.g., as shown in Example 415), and pairs the data with regular BCH, RS, or other codes. k lines and k The columns are encoded (e.g., example 415 with only system bit 420, parity bit 425 and parity bit 430).

[0110] Sending a WCD may transmit the system bits and parity bits of rows and columns for processing by a decoder (e.g., a product code decoder) receiving the WCD. The decoder begins decoding rows, and if it detects an error, it continues decoding columns. This is considered one iteration. If the decoder fails (e.g., the error is still not corrected), it can begin a second iteration by re-decoding the rows (e.g., after the first iteration, some bits have been decoded, and the second iteration needs to correct fewer errors). For example, if a row is not correctly decoded, there may be at most one error across all columns, which can be corrected using BCH, RS, or other codes. In some communications, product code encoding schemes may add parity bits to the parity bits of rows and / or columns, as shown in the example of parity bits 435 being generated from the parity bits of example 415.

[0111] For communications with relatively high decoding rates (such as some Asia-Pacific Hertz (sub-THz) bands), product coding may be a suitable decoding method. When using product coding, the overall decoding rate is approximately ( k / n )^2, and the decoding rate for each row and each column is 1 / 2. k / n (It is higher than the overall decoding rate). Because the higher the code rate, the lower the power consumption, thus reducing the overall power consumption and complexity.

[0112] While a higher number of decoding dimensions and / or the addition of parity bits can improve the accuracy of low SNR communication, a higher number of decoding dimensions and the addition of parity bits reduce the number of available resources (e.g., resource elements) that can be used to carry the communication payload, which may reduce spectral efficiency. Alternatively, using too low a number of decoding dimensions may increase the bit error rate of the communication, which may also reduce spectral efficiency.

[0113] In some networks (such as sub-THz networks), WCD can communicate using a wide bandwidth (e.g., 4 GHz or higher) that includes portions with low SNR and portions with high SNR. In this case, a first number of decoding dimensions may be applied to one or more first portions of the communication, and a second number of decoding dimensions and / or parity bits regenerating parity may be applied to one or more second portions of the communication.

[0114] Bit loading is a communication scheme in which communication involves different code rates under different constellation diagrams, or where the communication scheme involves different rate matching features (such as truncation). However, associated with different rate matching configurations per allocation, bit loading can have relatively high complexity at the receiver, which can consume power and computational resources. Additionally or alternatively, performing bit loading with different rate matching configurations may lead to increased decoding latency, which could result in communication errors associated with communication scheduling.

[0115] In some aspects described herein, transmitting a WCD can transmit communication with different parts, each with a different encoding scheme. For example, a first part may have a first parity bit mapping scheme and a second parity bit mapping scheme, wherein the first parity bit mapping scheme differs from the second parity bit mapping scheme. In some aspects, the first parity bit mapping scheme may be associated with a higher number of parity bits compared to the second parity bit mapping scheme. Thus, additional parity bits can be used for some parts of the communication (e.g., parts associated with relatively low SNR), while fewer parity bits can be used for other parts of the communication (e.g., parts associated with relatively high SNR). By using different parity bit mapping schemes for different parts of the communication, the communication can reduce decoding errors (e.g., compared to a single parity bit mapping scheme with too few parity bits), reduce unnecessary overhead (e.g., compared to a single parity bit mapping scheme with too many parity bits), and / or save power and / or computational resources that might otherwise be used to decode the communication using different rate-matching configurations.

[0116] In some examples, transmitting a WCD can use bandwidth that includes low SNR regions, medium SNR regions, and high SNR regions (e.g., high relative to low SNR regions) to transmit communication. Transmitting a WCD may apply a first parity bit mapping scheme to the low SNR region, which has product codes and parity bit regeneration parity bits. Transmitting a WCD may apply a second parity bit mapping scheme to the medium SNR region, which has product codes but no parity bit regeneration parity bits. Transmitting a WCD may apply a third parity bit mapping scheme to the high SNR region, which does not have product codes (e.g., a 1D BCH is applied).

[0117] In some aspects, the receiving WCD can receive an indication of the modulation and decoding scheme (MCS) for communication (e.g., received within the Physical Downlink Control Channel (PDCCH)) and can configure the code rate (e.g., BCH code rate) for decoding that communication. The receiving WCD can receive data signals via symbols and / or frequency resources of the Physical Downlink Shared Channel (PDSCH). The receiving WCD can receive and / or identify each allocated code rate (e.g., portions with different code rates and / or parity bit mapping schemes). Based on the data signal, the receiving WCD can identify the log-likelihood ratio (LLR) of the data signal to obtain preliminary values ​​for each resource (e.g., resource element) of the data channel. The receiving WCD can identify a decoder mode vector indicating the type of decoding available for each allocation (e.g., associated with indications from network nodes and / or parameters associated with communication as observed by the receiving WCD).

[0118] The received WCD can identify whether a portion of the communication (e.g., an allocation) is associated with a high bit rate (e.g., a bit rate that meets a threshold). If so, the received WCD can decode that portion of the communication using 1D decoding (e.g., row decoding via a BCH decoder or RS decoder). If not, the received WCD can identify whether that portion of the communication is associated with a medium bit rate. If so, the received WCD can decode that portion of the communication using 2D decoding (e.g., row and column decoding via a BCH decoder or RS decoder). However, in some aspects, the received WCD may first attempt to use 1D decoding, and if 1D decoding fails, it may subsequently use second-dimensional decoding (e.g., if row-only attempts fail, column decoding is also performed). If 2D decoding fails but one or more bits are corrected, the received WCD may perform another iteration of 2D decoding (e.g., including first attempting to decode the communication using 1D decoding, and then attempting to decode the communication using the second dimension). The received WCD may perform iterations until an iteration limit is reached or until decoding is successful (e.g., by parity checking).

[0119] If the receiving WCD identifies this portion of the communication as not associated with either a high or medium bit rate, the receiving WCD can use a decoding scheme that includes parity bit regeneration. In this case, the receiving WCD may attempt to decode the first dimension (e.g., all rows) using 1D decoding (e.g., a BCH decoder or RS decoder). If 1D decoding fails (e.g., parity check fails), the receiving WCD may apply decoding to the parity bits of the 1D decoding (e.g., all parity bit rows). If decoding still fails, the receiving WCD may decode in the second dimension (e.g., all columns). If decoding still fails, the receiving WCD may decode the parity bits in the second dimension (e.g., all parity bit columns). If decoding still fails, the receiving WCD may return to attempting 1D decoding and continue adding additional decoding operations until the iteration limit is reached or until decoding succeeds.

[0120] In these examples, each decoding operation (e.g., for rows, columns, and / or parity bits) can use a single decoder, such as a BCH decoder or an RS decoder. Based at least in part on using a single decoder for each part of the communication (including parts with different parity bit mapping schemes), the received WCD can be decoded with reduced complexity, saving power and computational resources and / or reducing the latency associated with decoding the communication.

[0121] In some aspects, the UE (e.g., transmitting or receiving WCD) may report (e.g., at connection establishment) the ability of each allocation of communication to support configurable codes. The UE may indicate in this report the supported decoding options, such as no product code, product code with parity bit regenerated, product code without parity bit regenerated, or any other configuration that changes the decoding rate while maintaining a shared decoding unit (e.g., BCH decoding or RS decoding). The UE may report the expected gap between each configuration by rank sum and / or by MCS, etc.

[0122] Once the UE is in connected mode, network nodes can transmit different decoding rate signaling via bit vectors, for example, representing the code rate for each resource element, each resource block (RB), each subband, each code block, and / or each group of code blocks. In some aspects, this vector can be compressed. For example, the vector can be indicated by differentially analyzing adjacent values. Depending on the coherence bandwidth, adjacent subcarriers may have relatively high correlation and the same code rate. This can result in a differential vector that is mostly zero, which can be efficiently compressed using compression techniques such as Huffman compression. In some aspects, the report can indicate the differential relative to the previous report to reduce non-zero values ​​and achieve further compression.

[0123] In some aspects, network nodes can indicate different decoding rates by indicating parameters used by the UE to identify the parts of communication with different decoding rates. For example, a network node can send indications of multiple thresholds associated with one or more of a channel energy value, capacity value, and / or SNR value, which define ranges associated with different code rates. In some aspects, different configurations can have different thresholds and / or different code rates associated with meeting or not meeting these thresholds.

[0124] In some aspects, the UE may identify different decoding rates for different portions of the communication based at least in part on SRS channel estimation and reciprocity assumptions. In some aspects, the UE may identify different decoding rates based at least in part on CSF reports associated with the downlink channel. In some aspects, the UE and / or network nodes may indicate the expected code rate for each allocation (e.g., a portion of the communication).

[0125] In some aspects, network nodes may indicate different decoding rates, thresholds, and / or parameters for the UE to identify different decoding rates, wherein such indication is within RRC messages, MAC CEs, and / or downlink control information (DCIs) (e.g., according to Doppler extension). In some aspects, network nodes may include such indication in periodic and / or aperiodic communications.

[0126] In some aspects, the UE sends feedback associated with indications of different decoding rates (e.g., and the number of parity bits). For example, the UE may indicate whether a different decoding rate configuration is acceptable or unacceptable to the UE. In some examples, the UE may collect statistics on the number of iterations for each region and whether decoding has passed, at least in part, based on different decoding rates.

[0127] Although described in the context of the UE and network nodes, or transmitting and receiving WCDs, the described features can be used within the backhaul network (such as between one or more IAB nodes) to optimize the link between the master and slave network nodes. Additionally or alternatively, the described features can be used in association with Physical Uplink Shared Channel (PUSCH) transmission, where each network node is configured with an allocated UE PUSCH code rate.

[0128] Figure 5 This is a diagram illustrating example 500 associated with the use of multiple parity bit mapping schemes for communication, according to this disclosure. Figure 5As shown, a first WCD (e.g., UE 120, network node 110, IAB node, CU, DU, and / or RU) may communicate with a second WCD (e.g., UE 120, network node 110, IAB node, CU, DU, and / or RU). In some aspects, the first and second WCDs may be part of a wireless network (e.g., wireless network 100). The first and second WCDs may... Figure 5 The operation shown has been performed with a wireless connection already established.

[0129] As shown by reference numeral 505 in the attached figure, the first WCD can send configuration information, and the second WCD can receive the configuration information. In some aspects, the second WCD can receive the configuration information via one or more of the following: system information (e.g., Master Information Block (MIB) and / or System Information Block (SIB), RRC signaling, one or more MAC CEs and / or DCIs, etc.

[0130] In some aspects, the configuration information may indicate one or more candidate configuration and / or communication parameters. In some aspects, these one or more candidate configuration and / or communication parameters may be selected, activated, and / or deactivated by subsequent indications. For example, a subsequent indication may select a candidate configuration and / or communication parameter from the one or more candidate configuration and / or communication parameters. In some aspects, subsequent indications (e.g., the indications described herein) may include dynamic indications, such as one or more MAC CEs and / or one or more DCI messages, etc.

[0131] In some respects, configuration information may instruct the second WCD to send indications of multiple parity bit mapping schemes (e.g., with different decoding rates) that support different parts (e.g., allocations) used for communication.

[0132] The second WCD can be configured at least in part based on configuration information. In some respects, the second WCD can be configured to perform one or more of the operations described herein, at least in part based on configuration information.

[0133] As shown by reference numeral 510 in the accompanying drawings, the second WCD can send a capability report and the first WCD can receive the capability report. The capability report can indicate whether the second WCD supports a feature and / or one or more parameters associated with that feature. For example, capability information can indicate the capability and / or parameters for receiving communication with different parity bit mapping schemes (e.g., different code rates) for different parts of the communication (e.g., at different allocations). One or more operations described herein can be based on the capability information in the capability report. For example, the second WCD can perform communication based on the capability information, or can receive configuration information based on that capability information.

[0134] In some aspects, the configuration information and / or capability report described in conjunction with reference to reference numeral 505 may include information transmitted via multiple communications. Additionally or alternatively, the first WCD may transmit the configuration information or communications including at least a portion of the configuration information before and / or after the second WCD transmits the capability report. For example, the first WCD may transmit a first portion of the configuration information before the capability report, the second WCD may transmit at least a portion of the capability report, and the first WCD may transmit a second portion of the configuration information after receiving the capability report.

[0135] As indicated by reference numeral 515 in the accompanying drawings, the second WCD may send an indication of support for multiple parity bit mapping schemes and / or supported or requested parameters, and the first WCD may receive this indication. In some aspects, the second WCD may send the indication of support via RRC messages, MAC CE, uplink control information (UCI), and / or in conjunction with the capability report described in reference numeral 510. In some aspects, the indication of support may be associated with communications, sets of communications, time windows, and / or bandwidth, etc.

[0136] In some aspects, indications of supported or requested parameters may include indications of requested frequency domain gaps between multiple parity bit mapping schemes. For example, a second WCD may indicate that, in order to support multiple parity bit mapping schemes, gaps in the frequency domain are requested so that the second WCD can isolate portions of communication with different parity bit mapping schemes. In some aspects, this indication may indicate requested frequency domain gaps for different ranks, requested frequency domain gaps for different MCSs, requested frequency domain gaps for different frequency ranges, and / or requested frequency domain gaps for different bandwidth portions (BWPs).

[0137] As shown by reference numeral 520 in the attached figure, the second WCD can receive the assignment of a parity bit mapping scheme to a frequency range and / or an indication of parameters used to identify the assignment, and the first WCD can transmit this indication. In some aspects, the first WCD can transmit the indication of the assignment via RRC signaling, MAC CE signaling, and / or DCI signaling. In some aspects, the indication of the assignment can indicate the code rate and / or parity bit mapping scheme associated with resource elements, RBs, subbands, code blocks, and / or code block groups.

[0138] In some aspects, the indication of assignment may include an indication of compression. For example, the indication of assignment may include an indication of the difference between subbands and / or the difference relative to a previously indicated assignment. In some aspects, the indication of assignment may include a vector-based indication associated with different portions of the bandwidth (e.g., substantially equal portions).

[0139] In some respects, indications of the parameters used to identify the assignment may include indications of one or more channel energy thresholds, one or more capacity thresholds, and / or one or more SNR thresholds.

[0140] In some aspects, the parity bit mapping scheme may be based at least in part on SRS channel estimation (e.g., reciprocity), CSF reports, and / or indications of parity bit mapping schemes requested by the UE. For example, the first WCD may use SRS channel estimation, CSF reports, and / or UE requests to identify portions of communication that are likely to have different SNRs as observed by the second WCD (e.g., portions associated with bandwidth). The first WCD may assign different parity bit mapping schemes to different portions at least in part based on SNR (e.g., increasing parity bits for low SNR portions and decreasing parity bits for high SNR portions).

[0141] As indicated by reference numeral 525, the second WCD may identify the assignment. In some aspects, the second WCD may identify the assignment at least in part based on an indication of the assignment, as indicated by reference numerals 520 and / or 505. In some aspects, the second WCD may identify the assignment at least in part based on one or more parameters (e.g., indicated by or to the first WCD, etc.). For example, the second WCD may identify the parity bit mapping scheme at least in part based on one or more channel energy thresholds (e.g., compared to one or more channel energies measured in each part), one or more channel capacity thresholds (e.g., compared to one or more capacities measured at least in each part), and / or one or more SNR thresholds (e.g., compared to one or more SNRs measured in each part), etc.

[0142] In some aspects, a first parity bit mapping scheme may be associated with a first number of parity bit dimensions and / or a first number of parity bits. In some aspects, a second parity bit mapping scheme may be associated with a second number of parity bit dimensions and / or a second number of parity bits (e.g., different from the first number of parity bit dimensions and / or the first number of parity bits). Similarly, a first parity bit mapping scheme may be associated with a first code rate, and a second parity bit mapping scheme may be associated with a second code rate different from the first code rate.

[0143] As indicated by reference numeral 530 in the accompanying drawings, the second WCD can receive communication, and the first WCD can transmit the communication. Receiving communication may include receiving communication via a bandwidth comprising multiple portions (e.g., allocations). The multiple portions may be associated with different SNRs. In some aspects, the multiple portions may be defined by SNR, capacity, and / or received energy as measured and / or observed by the second WCD. In some aspects, the multiple portions may be defined by indications from the second WCD or the first WCD.

[0144] In some aspects, the communication may have a first parity bit mapping scheme (e.g., applied to a first portion) and a second parity bit mapping scheme (e.g., applied to a second portion). In some aspects, the first parity bit mapping scheme may be associated with a first subcarrier, and the second parity bit mapping scheme may be associated with a second subcarrier. In some aspects, the communication may have an additional parity bit mapping scheme applied to an additional portion of the communication (e.g., an additional portion of the bandwidth on which the first WCD transmits the communication).

[0145] As shown by reference numeral 535 in the accompanying drawings, the second WCD can apply a decoder to a first part of the communication having a first parity bit mapping scheme and a second part of the communication having a second parity bit mapping scheme. For example, the second WCD can apply the same decoder to both the first and second parts. In some aspects, the second WCD can apply the same decoder a different number of times (e.g., a different number of iterations and / or on multiple dimensions, etc.) when decoding the first part compared to when decoding the second part, or it can support applying the same decoder a different number of times, even if not all supported applications are used (e.g., if decoding is successful before decoding is performed on all supported dimensions). In some aspects, the decoder can be a BCH decoder or an RS decoder.

[0146] As indicated by reference numeral 540 in the attached figure, the second WCD may send an indication of successful decoding, and the first WCD may receive such indication. In some aspects, the second WCD may indicate, via the indication of successful decoding, whether the indication of assignment and / or parameters used to identify the assignment is effective in balancing error reduction and low bit rate.

[0147] By using different parity bit mapping schemes for different parts of the communication, the communication can reduce decoding errors (e.g., compared to a single parity bit mapping scheme with too few parity bits), reduce unnecessary overhead (e.g., compared to a single parity bit mapping scheme with too many parity bits), and / or save power and / or computational resources that might otherwise be used to decode the communication using different rate-matching configurations.

[0148] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The examples described are different.

[0149] Figure 6 This is a diagram illustrating example 600 associated with the use of multiple parity bit mapping schemes for communication, according to this disclosure. Figure 6In this context, the first WCD (e.g., UE 120, network node 110, IAB node, CU, DU, and / or RU) may communicate with the second WCD (e.g., UE 120, network node 110, IAB node, CU, DU, and / or RU). In some aspects, the first and second WCDs may be part of a wireless network (e.g., wireless network 100). The first and second WCDs may... Figure 6 The operation shown has been performed with a wireless connection already established.

[0150] like Figure 6 As shown, communication can be transmitted and received via multiple sets of one or more subcarriers. Each set may experience different channel effects, such as noise, interference, and / or propagation loss. A first set 605 of one or more subcarriers may include a set of system bits organized into rows and columns. The first set 605 may be configured with parity bits to be applied to rows and parity bits to be applied to columns.

[0151] The gap 610 can separate a first set 605 of one or more subcarriers from a second set 615. The second set 615 may include a set of system bits organized into rows and columns. The second set 615 may be configured with parity bits to be applied only to rows.

[0152] The gap 620 can separate a second set 615 of one or more subcarriers from a third set 625. The third set 625 may include a set of system bits organized into rows and columns. The third set 625 may be configured with parity bits to be applied to rows, parity bits to be applied to columns, and parity bits to be applied to parity bits (e.g., parity bits in rows and / or columns).

[0153] As indicated above, Figure 6 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6 The examples described are different.

[0154] Figure 7 This is a diagram illustrating an example process 700 performed, for example, at a WCD or a device of a WCD, according to this disclosure. Example process 700 is an example of an operation performed by a device or WCD (e.g., UE 120, network node 110, IAB node, and / or a second WCD, etc.) associated with multiple parity bit mapping schemes for communication.

[0155] like Figure 7 As shown, in some aspects, process 700 may include sending an indication of multiple parity bit mapping schemes supporting communication (box 710). For example, WCD (e.g., using communication manager 140 or 150 and / or Figure 9The transmitting component 904 described herein can transmit instructions for supporting multiple parity bit mapping schemes for communication, as described above.

[0156] like Figure 7 Further shown, in some aspects, process 700 may include receiving communication having a first parity bit mapping scheme and a second parity bit mapping scheme, the first parity bit mapping scheme being different from the second parity bit mapping scheme (box 720). For example, WCD (e.g., using communication manager 140 or 150 and / or Figure 9 The described receiving component 902 can receive communication having a first parity bit mapping scheme and a second parity bit mapping scheme, the first parity bit mapping scheme being different from the second parity bit mapping scheme, as described above.

[0157] Process 700 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0158] In the first aspect, a first parity bit mapping scheme is associated with a first subcarrier of communication, and a second parity bit mapping scheme is associated with a second subcarrier of communication.

[0159] In a second aspect, either alone or in combination with the first aspect, process 700 includes receiving an instruction for the assignment of a first parity bit mapping scheme and a second parity bit mapping scheme, or identifying the assignment at least in part based on one or more parameters.

[0160] In the third aspect, receiving an instruction on an assignment, either alone or in combination with one or more of the first and second aspects, includes receiving an instruction on one or more of a code rate or parity bit mapping scheme associated with one or more of an element, resource block, subband, decoded block, or group of decoded blocks.

Figure 15 In this context, the first WCD (e.g., UE 120, network node 110, IAB node, CU, DU, and / or RU) can communicate with the second WCD (e.g., UE 120, network node 110, IAB node, CU, DU, and / or RU) using communication with multiple parity bit mapping schemes.

[0241] like Figure 15As shown, communication can be received at a second WCD (e.g., a receiving WCD), where different levels of received power are present for different frequency ranges (e.g., sets of subbands). For example, frequency range 1505 includes received power within a first power range, frequency range 1510 includes received power within a second power range, frequency range 1515 includes received power within a third power range, frequency range 1520 includes received power within a second power range, frequency range 1525 includes received power within a first power range, frequency range 1530 includes received power within a second power range, frequency range 1535 includes received power within a first power range, and frequency range 1540 includes received power within a second power range.

For example, frequency ranges 1505, 1525, and 1535 may have a first parity bit mapping scheme, which is at least in part based on having the highest received power and the fewest number of parity bits. Frequency ranges 1510, 1520, 1530, and 1540 may have a second parity bit mapping scheme, which is at least in part based on having a second highest received power and a second fewest number of parity bits. Frequency range 1515 may have a third parity bit mapping scheme, which is at least in part based on having the lowest received power and the highest number of parity bits.
