[0002] Aspects of the present disclosure generally relate to wireless communication and specifically relate to techniques, apparatuses, and methods associated with time interleaving on a multicast transport channel.DESCRIPTION OF THE RELATED TECHNOLOGY

[0003] Wireless communication systems are widely deployed to provide various services, which may involve carrying or supporting voice, text, other messaging, video, data, or other traffic. Typical wireless communication systems may employ multiple-access radio access technologies (RATs) capable of supporting communication among multiple wireless communication devices including user devices or other devices by sharing the available system resources (for example, time domain resources, frequency domain resources, spatial domain resources, or device transmit power, among other examples). Such multiple-access RATs are supported by technological advancements that have been adopted in various telecommunication standards, which define common protocols that enable different wireless communication devices to communicate on a local, municipal, national, regional, or global level. An example telecommunication standard is New Radio (NR). NR, which also may be referred to as 5G, is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP). As the demand for connectivity continues to increase, further improvements in NR may be implemented, and other RATs, such as 6G and beyond, may be introduced to enable new applications and facilitate new use cases.

[0004] Some wireless networks support a multicast transport channel. A multicast transport channel is a transport channel for carrying data intended for multiple user equipments (UEs). The multicast transport channel may support multicast transmissions from a network node to a group of UEs in a coverage area of the network node.0097-6179PCTSUMMARY

[0010] Aspects of the present disclosure may generally be implemented by or as a method, apparatus, system, computer program product, non-transitory computer-readable medium, user equipment, network node, wireless communication device, or processing system as substantially described in the Detailed Description with reference to, and as illustrated by, the accompanying drawings. Details of one or more implementations of the subject matter described in this disclosure are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages will become apparent from the description, the drawings, and the claims.

[0018] A multicast transport channel may not permit hybrid automatic repeat request (HARQ) retransmissions. Accordingly, the multicast transport channel may be configured to operate with a low block error rate (BLER). For example, the multicast transport channel may be configured for time interleaving, which may reduce the BLER.

[0019] Time interleaving is a technique that involves rearranging data symbols in the time domain to improve resistance to channel impairments, such as fading and burst errors, in a wireless communication system. Time interleaving may involve distributing consecutive symbols over multiple transmission time intervals to reduce the impact of localized signal degradation. For example, for a transport block, time interleaving may include transmitting redundancy versions of the transport block over multiple non-contiguous slots. A user equipment (UE) may receive and decode the redundancy versions using a circular buffer. The circular buffer is a data structure used for storing and managing data in a fixed-size buffer, where read and write operations progress cyclically.0097-6179PCT

[0020] If a multicast transport channel is configured outside the capabilities of the UE, particularly with respect to the circular buffer, multicast communications may be lost or corrupted at the UE. For example, if the transport block size is too large for the circular buffer, the circular buffer may overflow, which may result in data being overwritten or lost before the UE is able to decode the data.

[0021] Various aspects relate generally to multicast transport channels. Some aspects more specifically relate to time interleaving on a multicast transport channel. In some aspects, a UE may communicate one or more capability reports associated with UE support for time interleaving on the multicast transport channel. A network node may configure time interleaving on the multicast transport channel in accordance with the one or more capability reports.

[0022] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some aspects, the described techniques can be used to configure time interleaving on the multicast transport channel in accordance with the capabilities of the UE, which may improve network performance and satisfy BLER requirements for multicast transport channel communications. In some aspects, as a result of a network node configuring the time interleaving on the multicast transport channel in accordance with the capabilities of the UE, the UE may receive and decode multicast transport channel communications with reduced risk of experiencing a buffer overflow or lost communications.

[0023] 5G New Radio (NR) may support enhanced mobile broadband (eMBB) access, Internet of Things (loT) networks or reduced capability (RedCap) device deployments, ultrareliable low-latency communication (URLLC) applications, or massive machine-type communication (mMTC), among other examples. To support these and other target verticals, a wireless communication system may be designed to implement a modularized functional infrastructure, a disaggregated and service-based network architecture, network function virtualization, network slicing, multi-access edge computing, millimeter wave (mmWave) technologies including massive multiple-input multiple -output (MIMO), beamforming, loT device or RedCap device connectivity and management, industrial connectivity, licensed and unlicensed spectrum access, sidelink and other device-to-device direct communication (for example, cellular vehicle-to-everything (CV2X) communication), frequency spectrum expansion, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, device aggregation, advanced duplex communication (for example, sub-band full-duplex (SBFD)), multiple-subscriber implementations, high-precision positioning, radio frequency (RF) sensing, network energy savings (NES), low-power signaling and radios, or artificial intelligence or machine learning (AI / ML), among other examples.0097-6179PCT

[0024] The foregoing and other technological improvements may support use cases, such as wireless fronthauls, wireless midhauls, wireless backhauls, wireless data centers, extended reality (XR) and metaverse applications, meta services for supporting vehicle connectivity, holographic and mixed reality communication, autonomous and collaborative robots, vehicle platooning and cooperative maneuvering, sensing networks, gesture monitoring, human-brain interfacing, digital twin applications, asset management, and universal coverage applications using non-terrestrial or aerial platforms, among other examples.

[0025] The methods, operations, apparatuses, and techniques described herein may enable one or more of the foregoing technologies or new technologies or support one or more of the foregoing use cases or new use cases.

[0026] Fig. 1 is a diagram illustrating an example of a wireless communication network 100. The wireless communication network 100 may be or may include elements of a 5G network or a 6G network, among other examples. The wireless communication network 100 may include multiple network nodes 110. For example, in Fig. 1, the wireless communication network 100 includes multiple network nodes 110, including a network node 110a and a network node 110b (each of which also may be referred to herein simply as a “network node 110”). The network nodes 110 may support communications with multiple UEs 120. For example, in Fig. 1, the network nodes 110 support communication with a UE 120a, a UE 120b, and a UE 120c (each of which also may be referred to herein simply as a “UE 120”). In some examples, a UE 120 also may communicate with other UEs 120 and a network node 110 also may communicate with a core network and with other network nodes 110.

[0027] The network nodes 110 and the UEs 120 of the wireless communication network 100 communicate using the electromagnetic spectrum, which may be subdivided into various licensed or unlicensed operating bands, frequency ranges, component carriers, or channels that define associated frequencies available for communications. In some examples, each of the network nodes 110 and the UEs 120 may communicate using one or multiple component carriers in one or more operating bands or ranges. Typically, various operating bands are defined as frequency range designations FR1 (410 MHz through 7.125 GHz), FR2 (24.25 GHz through 52.6 GHz), FR3 (7.125 GHz through 24.25 GHz), FR4a or FR4-1 (52.6 GHz through 71 GHz), FR4 (52.6 GHz through 114.25 GHz), and FR5 (114.25 GHz through 300 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “sub-6 GHz” band in some documents and articles. Similarly, FR2 is often referred to (interchangeably) as a “millimeter wave” band in some documents and articles.

[0028] A network node 110 or a UE 120 may include one or more devices, components, or systems that enable communication with other devices, components, or systems of the wireless communication network 100. For example, a UE 120 and a network node 110 may each include0097-6179PCTone or more chips, system -on-chips (SoCs), chipsets, packages, or devices that individually or collectively constitute or comprise a processing system. As shown in Fig. 1, each UE 120 includes a processing system 140 and each network node 110 includes a processing system 145. A processing system (for example, the processing system 140 or the processing system 145) includes processor (or “processing”) circuitry in the form of one or multiple processors, microprocessors, processing units (such as central processing units (CPUs), graphics processing units (GPUs), neural processing units (NPUs) (also referred to as neural network processors or deep learning processors (DEPs)), or digital signal processors (DSPs)), processing blocks, application-specific integrated circuits (ASICs), programmable logic devices (PLDs), or other discrete gate or transistor logic or circuitry (any one or more of which may be generally referred to herein individually as a “processor” or collectively as “the processor” or “the processor circuitry”). Such processors may be individually or collectively configurable or configured to perform various functions or operations described herein. A group of processors collectively configurable or configured to perform a set of functions may include a first processor configurable or configured to perform a first function of the set and a second processor configurable or configured to perform a second function of the set. In some other examples, each of a group of processors may be configurable or configured to perform a same set of functions.

[0029] The processing system 140 and the processing system 145 may each include memory circuitry in the form of one or multiple memory devices, memory blocks, memory elements, or other discrete gate or transistor logic or circuitry, each of which may include or implement tangible storage media, such as random-access memory, or read-only memory, or combinations thereof (any one or more of which may be generally referred to herein individually as a “memory” or collectively as “the memory” or “the memory circuitry”). One or more of the memories may be coupled (for example, operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) with one or more of the processors. One or more of the memories may individually or collectively store processor-executable code or instructions (such as software) (for example, which may be referred to as “one or more code-storing memories” or “code-storing memory circuitry”). For example, “code-storing memory” or “code-storing memory circuitry” refers to memory (or memory circuitry) that is configured to store processor-executable code or instructions. The processor-executable code or instructions, when executed by one or more of the processors, may configure one or more of the processors (or processing circuitry) to perform various functions or operations described herein.Additionally, or alternatively, in some examples, one or more of the processors may be configured to perform various functions or operations described herein without requiring configuration by software. Software shall be construed broadly to mean instructions, instruction0097-6179PCTsets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, or functions, among other examples, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

[0030] The processing system 140 and the processing system 145 may each include or be coupled with one or more modems (such as a cellular (for example, a 5G or 6G compliant) modem). In some examples, one or more processors of the processing system 140 or the processing system 145 may include or implement one or more of the modems. The processing system 140 and the processing system 145 also may include or be coupled with multiple radios (collectively “the radio”), multiple RF chains, or multiple transceivers, each of which may in turn be coupled with one or more of multiple antennas. In some examples, one or more processors of the processing system 140 or the processing system 145 may include or implement one or more of the radios, RF chains, or transceivers. An RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs), or other devices that convert between an analog signal (such as for transmission or reception via an air interface) and a digital signal (such as for processing by the processing system 140 or by the processing system 145).

[0031] A network node 110 and a UE 120 may each include one or multiple antennas or antenna arrays. Typical network nodes 110 and UEs 120 may include multiple antennas, which may be organized or structured into one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, among other examples. As used herein, the term “antenna” can refer to one or more antennas, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays. The term “antenna panel” can refer to a group of antennas (such as antenna elements) arranged in an array or panel, which may facilitate beamforming by manipulating parameters associated with the group of antennas. The term “antenna module” may refer to circuitry including one or more antennas as well as one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device, such as the network node 110 and the UE 120.

[0032] A network node 110 may be, may include, or also may be referred to as an NR network node, a 5G network node, a 6G network node, a Node B, a gNB, an access point (AP), a transmission reception point (TRP), a network entity, a network element, a network equipment, or another type of device, component, or system included in a radio access network (RAN). In various deployments, a network node 110 may be implemented as a single physical node (for example, a single physical structure) or may be implemented as two or more physical0097-6179PCTnodes (for example, two or more distinct physical structures). For example, a network node 110 may be a device or system that implements a part of a radio protocol stack, a device or system that implements a full radio protocol stack (such as a full gNB protocol stack), or a collection of devices or systems that collectively implement the full radio protocol stack. For example, and as shown, a network node 110 may be an aggregated network node having an aggregated architecture, meaning that the network node 110 may implement a full radio protocol stack that is physically and logically integrated within a single physical structure in the wireless communication network 100. For example, an aggregated network node 110 may include a single standalone base station or a single TRP that operates with a full radio protocol stack to enable or facilitate communication between a UE 120 and a core network of the wireless communication network 100.

[0033] Alternatively, and as also shown, a network node 110 may be a disaggregated network node 110 (sometimes referred to as a disaggregated base station), having a disaggregated architecture, meaning that the network node 110 may operate with a radio protocol stack that is physically distributed or logically distributed among two or more nodes in the same geographic location or in different geographic locations. In some deployments, disaggregated network nodes 110 may be used in an integrated access and backhaul (IAB) network, in an open radio access network (O-RAN) (such as a network configuration in compliance with the O-RAN Alliance), or in a virtualized radio access network (vRAN), also known as a cloud radio access network (C-RAN), to facilitate scaling by separating network functionality into multiple units or modules that can be individually deployed.

[0034] The disaggregated network nodes 110 of the wireless communication network 100 may include one or more central units (CUs), one or more distributed units (DUs), and one or more radio units (RUs). A CU may host one or more higher layers, such as a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, and a service data adaptation protocol (SDAP) layer, among other examples. A DU may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, or one or more higher physical (PHY) layers depending, at least in part, on a functional split, such as a functional split defined by the 3GPP. In some examples, a DU also may host a lower PHY layer that is configured to perform functions, such as a fast Fourier transform (FFT), an inverse FFT (IFFT), beamforming, or physical random access channel (PRACH) extraction and filtering, among other examples. An RU may perform RF processing functions or lower PHY layer functions, such as an FFT, an IFFT, beamforming, or PRACH extraction and filtering, among other examples, according to a functional split, such as a lower layer split (EES). In such an architecture, each RU can be operated to handle over the air (OTA) communication with one or more UEs 120. In some examples, a single network node 110 may include a combination of0097-6179PCTone or more CUs, one or more DUs, or one or more RUs. In some examples, a CU, a DU, or an RU may be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), among other examples, which may be implemented as a virtual network function, such as in a cloud deployment.

[0035] In some examples, the wireless communication network 100 may be a heterogeneous network that includes network nodes 110 of various types. Different types of network nodes 110 may generally operate on the same or different operating bands, transmit at different power levels, or serve different coverage areas, each of which may be referred to as or associated with a particular cell 130 (for example, a cell 130a and a cell 130b).

[0036] The UEs 120 may be physically dispersed throughout the coverage area of the wireless communication network 100, and each UE 120 may be stationary or mobile. A UE 120 may be, may include, or also may be referred to as an access terminal, a mobile station, a client device, or a subscriber unit. A UE 120 may be, include, or be coupled with a cellular phone (for example, a smart phone), 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, a camera, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (for example, a smart watch, smart clothing, smart glasses, a smart wristband, or smart jewelry), a gaming device, an entertainment device (for example, a music device, a video device, or a satellite radio), an XR device, a vehicular component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device), an artificially intelligent robot or other device implementing artificial intelligence, a UE function of a network node, or any other suitable device or function that may communicate in the wireless communication network 100.

[0037] Some UEs 120 may be classified according to different categories in association with different complexities or different capabilities. UEs 120 in a first category may be associated with relatively low complexity or cost such as NB-IoT devices or eMTC UEs. UEs 120 in a second category may include higher complexity or cost devices, such as mission-critical loT devices, baseline UEs, high-tier UEs, advanced UEs, full-capability UEs, or premium UEs that are capable of URLLC, eMBB, or precise positioning in the wireless communication network 100. A third category of UEs 120 may have mid-tier complexity or capabilities (for example, capabilities between that of the UEs 120 of the first category and the UEs 120 of the second category). A UE 120 of the third category may be referred to as a reduced capability UE (“RedCap UE”), a mid-tier UE, an NR-Light UE, or an NR-Lite UE, among other examples.

[0038] In some examples, a network node 110 may be, may include, or may operate as an RU, a TRP, or a base station that communicates with one or more UEs 120 via a radio access0097-6179PCTlink (which may be referred to as a “Uu” link). The radio access link may include a downlink and an uplink. “Downlink” (or “DL”) refers to a communication direction from a network node 110 to a UE 120, and “uplink” (or “UL”) refers to a communication direction from a UE 120 to a network node 110. Downlink and uplink resources may include time domain resources (for example, frames, subframes, slots, and symbols), frequency domain resources (for example, frequency bands, component carriers (CCs), subcarriers, resource blocks, and resource elements), and spatial domain resources (for example, particular transmit directions or beams).

[0039] Frequency domain resources may be subdivided into bandwidth parts (BWPs). A BWP may be a block of frequency domain resources (for example, a continuous set of resource blocks (RBs) within a full component carrier bandwidth) that may be configured at a UE-specific level. A UE 120 may be configured with both an uplink BWP and a downlink BWP (which may be the same or different). Each BWP may be associated with its own numerology (indicating a sub-carrier spacing (SCS) and cyclic prefix (CP)). A BWP may be dynamically configured or activated (for example, by a network node 110 transmitting a downlink control information (DCI) configuration to the one or more UEs 120) or reconfigured (for example, in real-time or near-real-time) according to changing network conditions in the wireless communication network 100 or specific requirements of one or more UEs 120. An active BWP defines the operating bandwidth of the UE 120 within the operating bandwidth of the serving cell.

[0040] As used herein, a downlink signal may be or include a reference signal, control information, or data. For example, downlink reference signals include a primary synchronization signal (PSS), a secondary SS (SSS), an SS block (SSB) (for example, that includes a PSS, an SSS, and a physical broadcast channel (PBCH)), a demodulation reference signal (DMRS), a phase tracking reference signal (PTRS), a tracking reference signal (TRS), and a channel state information (CSI) reference signal (CSI-RS), among other examples. A downlink signal carrying control information or data may be transmitted via a downlink channel. Downlink channels may include one or more control channels for transmitting control information and one or more data channels for transmitting data. Downlink reference signals may be transmitted in addition to, or multiplexed with, downlink control channel communications or downlink data channel communications. A downlink control channel may be specifically used to transmit DCI from a network node 110 to a UE 120. DCI generally contains the information the UE 120 needs to identify RBs in a subsequent subframe and how to decode them, including a modulation and coding scheme (MCS) or redundancy version parameters. Different DCI formats carry different information, such as scheduling information in the form of downlink or uplink grants, slot format indicators (SFIs), preemption indicators (Pls), transmit power control (TPC) commands, hybrid automatic repeat request (HARQ)0097-6179PCTinformation, new data indicators (NDIs), among other examples. A downlink data channel may be used to transmit downlink data (for example, user data associated with a UE 120) from a network node 110 to a UE 120. Downlink control channels may include physical downlink control channels (PDCCHs), and downlink data channels may include physical downlink shared channels (PDSCHs). Control information or data communications may be transmitted on a PDCCH and PDSCH, respectively. For example, a PDCCH can carry DCI, while a PDSCH can carry a MAC control element (MAC-CE), an RRC message, or user data, among other examples. Each PDSCH may carry one or more transport blocks (TBs) of data.

[0041] As used herein, an uplink signal may include a reference signal, control information, or data. For example, uplink reference signals include a sounding reference signal (SRS), a PTRS, and a DMRS, among other examples. An uplink signal carrying control information or data may be transmitted via an uplink channel. An uplink channel may include one or more control channels for transmitting control information and one or more data channels for transmitting data. Uplink reference signals may be transmitted in addition to, or multiplexed with, uplink control channel communications or uplink data channel communications. An uplink control channel may be specifically used to transmit uplink control information (UCI) from a UE 120 to a network node 110. An uplink data channel may be used to transmit uplink data (for example, user data associated with a UE 120) from a UE 120 to a network node 110. Uplink control channels may include physical uplink control channels (PUCCHs), and uplink data channels may include physical uplink shared channels (PUSCHs). Control information or data communications may be transmitted on a PUCCH and PUSCH, respectively. For example, a PUCCH can carry UCI, while a PUSCH can carry a MAC-CE, an RRC message, or user data, among other examples. UCI can include a scheduling request (SR), HARQ feedback information (for example, a HARQ acknowledgement (ACK) indication or a HARQ negative acknowledgement (NACK) indication), uplink power control information (for example, an uplink TPC parameter), or CSI, among other examples. CSI can include a channel quality indicator (CQI) (indicative of downlink channel conditions to facilitate selection of transmission parameters, such as an MCS, by a network node 110), a precoding matrix indicator (PMI), a CSI-RS resource indicator (CRI) (for example, indicative of a beam used to transmit a CSI-RS), an SS / PBCH resource block indicator (SSBRI) (for example, indicative of a beam used to transmit an SSB), a layer indicator (LI), a rank indicator (RI), or measurement information (for example, a layer 1 (LI)- reference signal received power (RSRP) parameter, a received signal strength indicator (RS SI) parameter, a reference signal received quality (RSRQ) parameter, among other examples) which can be used for beam management, among other examples. Each PUSCH may carry one or more TBs of data.0097-6179PCT

[0042] The information (for example, data, control information, or reference signal information) transmitted by a network node 110 to a UE 120, or vice versa, may be represented as a sequence of binary bits that are mapped (for example, modulated) to an analog signal waveform (for example, a discrete Fourier transform (DFT)-spread-orthogonal frequency division multiplexing (OFDM) (DFT-s-OFDM) waveform or a CP-OFDM waveform) that is transmitted by the network node 110 or UE 120 over a wireless communication channel. In some examples, the network node 110 or the UE 120 (for example, using the processing system 145 or the processing system 140, respectively) may select an MCS (for example, an order of quadrature amplitude modulation (QAM), such as 64-QAM, 128-QAM, or 256-QAM, among other examples) for a downlink signal or an uplink signal. For example, the network node 110 may select an MCS for a downlink signal in accordance with UCI received from the UE 120 or may transmit, to the UE 120, an indication of an MCS to be applied for an uplink signal.

[0043] A network node 110 or a UE 120 (such as by using the processing system 145 or the processing system 140, respectively, or one or more coupled modems) may perform signal processing on the information (such as filtering, amplification, modulation, digital-to-analog conversion, an IFFT operation, multiplexing, interleaving, mapping, or encoding, among other examples) to generate a processed signal in accordance with the selected MCS. In some examples, the network node 110 or the UE 120 (for example, using the processing system 145 or the processing system 140, respectively, or one or more coupled encoders or modems) may perform a channel coding operation or a forward error correction (FEC) operation to control errors in transmitted information. For example, the network node 110 or the UE 120 may perform an encoding operation to generate encoded information (such as by selectively introducing redundancy into the information, typically using an error correction code (ECC), such as a polar code or a low-density parity-check (LDPC) code). The network node 110 or the UE 120 (for example, using the processing system 145 or one or more modems) may further perform spatial processing (for example, precoding) on the encoded information to generate one or more processed or precoded signals for downlink or uplink transmission, respectively. In some examples, the network node 110a or the UE 120a may perform codebook-based precoding or non-codebook-based precoding. Codebook-based precoding may involve selecting a precoder (for example, a precoding matrix) using a codebook. For example, the network node 110a may provide precoding information indicating which precoder, defined by the codebook, is to be used by the UE 120a. Non-codebook-based precoding may involve selecting or deriving a precoder based on, or otherwise associated with, one or more downlink or uplink signal measurements. The network node 110a or the UE 120a may transmit the processed downlink or uplink signals, respectively, via one or more antennas.0097-6179PCT

[0044] The network node 110a or the UE 120a may receive uplink signals or downlink signals, respectively, via one or more antennas. The network node 110a or the UE 120a (for example, using the processing system 145 or the processing system 140, respectively, or one or more coupled modems) may perform signal processing (for example, in accordance with the MCS) on the received uplink or downlink signals, respectively (such as filtering, amplification, demodulation, analog-to-digital conversion, an FFT operation, demultiplexing, deinterleaving, de-mapping, equalization, interference cancellation, or decoding, among other examples), to map the received signal(s) to a sequence of binary bits (for example, received information) that estimates the information transmitted by the network node 110 or the UE 120 via the downlink or uplink signals. The network node 110a or the UE 120a (for example, using the processing system 145 or the processing system 140, respectively, or a coupled decoder or one or more modems) may decode the received information (such as by using an ECC, a decoding operation, or an FEC operation) to detect errors or correct bit errors in the received information to generate decoded information. The decoded information may estimate the information transmitted via the downlink or uplink signals.

[0045] In some examples, a UE 120 and a network node 110 may perform MIMO communication. MIMO communication generally refers to transmitting or receiving multiple signals (such as multiple layers or multiple data streams) simultaneously over the same time and frequency resources. A network node 110 or a UE 120 may communicate using single-user MIMO or multi-user MIMO (MU-MIMO), the latter of which being used by a network node 110 to simultaneously transmit signals to multiple UEs 120. MIMO techniques may involve spatial multiplexing (multi-layer transmission) or beamforming. To implement beamforming, the amplitudes or phases of signals transmitted via antenna elements may be modulated and shifted relative to each other (such as by manipulating a phase shift, a phase offset, or an amplitude) to generate one or more beams. For example, a network node 110 may generate one or more beams 160a, and a UE 120 may generate one or more beams 160b. The term “beam” may refer to a directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction, a directional reception of a wireless signal from a transmitting device or otherwise in a desired direction, a direction associated with such a directional transmission or directional reception, a set of directional resources associated with a signal transmission or signal reception (for example, an angle of arrival, a horizontal direction, or a vertical direction), or a set of parameters or resources associated with one or more aspects of a directional signal, among other examples.

[0046] In some examples, a network node 110 or a UE 120 may implement massive MIMO, which may be associated with an increased (for example, “massive”) quantity of antennas at the network node 110 or at the UE 120, such as in a network implementing mmWave technology,0097-6179PCTwhich enables more precise beamforming or reduced interference. In some examples, the wireless communication network 100 may implement multi -TRP (mTRP) operation (including redundant transmission or reception on multiple TRPs) or non-coherent joint transmission (NC-JT).

[0047] The network node 110 and the UE 120 may establish a communication link or beam pair, and otherwise increase reliability, throughput, signal strength, or other signal properties for MIMO communications, by performing beam management operations, such as an initial beam acquisition operation, a beam refinement operation, or a beam recovery operation. For example, an initial beam acquisition operation may involve the network node 110 transmitting signals (for example, SSBs or other signals) via respective beams (for example, of the beams 160 of the network node 110) and the UE 120 receiving and measuring the signal(s) via respective beams of multiple beams (for example, from the beams 160 of the UE 120) to identify a best beam (or beam pair) for communication between the UE 120 and the network node 110. A beam refinement operation may involve a first device (for example, the UE 120 or the network node 110) transmitting signal(s) via a subset of beams (for example, identified based on, or otherwise associated with, measurements reported as part of one or more other beam management operations). A second device (for example, the network node 110 or the UE 120) may receive the signal(s) via a single beam (for example, to identify the best beam for communication from the subset of beams). The beam(s) may be identified or defined via one or more spatial parameters, such as a transmission configuration indicator (TCI) state or a quasi co-location (QCL) parameter, among other examples.

[0048] Some aspects and techniques as described herein may be implemented, at least in part, using an artificial intelligence (Al) program (for example, referred to herein as an “AI / ML model”), such as a program that includes a machine learning (ML) model or an artificial neural network (ANN) model. The AI / ML model may be deployed at one or more devices 165 (for example, one or more network nodes 110, one or more UEs 120, one or more servers, or one or more components of a cloud computing network, among other examples). For example, in a deployment in which AI / ML functionality is performed independently at a device 165, sometimes referred to as “overlay AI / ML,” the AI / ML model (or an instance or portion of the AI / ML model) may be deployed at a UE 120 (for example, by the processing system 140), a network node 110 (for example, by the processing system 145), one or more servers, or one or more components of a cloud computing network, among other examples. Additionally, or alternatively, in a deployment where AI / ML functionality is coordinated between different devices 165, sometimes referred to as “coordinated AI / ML,” or performed at all device and network layers, sometimes referred to as “native AI / ML,” the AI / ML model (or an instance of the AI / ML model) may be deployed at multiple devices 165 (for example, a first portion of the0097-6179PCTAI / ML model may be deployed at a UE 120 and a second portion of the AI / ML model may be deployed at a network node 110). In other examples of coordinated AI / ML or native AI / ML, a first AI / ML model may be deployed at a UE 120 and a second AI / ML model may be deployed at a network node 110. The AI / ML model(s) may be configured to enhance various aspects of the wireless communication network 100 (for example, to increase privacy, reliability, or efficient use of network bandwidth, or to reduce latency, among other examples). Lor example, the AI / ML model(s) may be trained to identify patterns or relationships in data corresponding to the wireless communication network 100, a device, or an air interface, among other examples. The AI / ML model(s) may support operational decisions relating to one or more aspects associated with wireless communications devices, networks, or services.

[0049] Accordingly, in some examples, the AI / ML model(s) may enable Al-as-a-Service (for example, an end-to-end AI / ML service via a user plane) for use cases, such as a self-organizing network (SON), minimization of drive test (MDT), quality of experience (QoE), positioning, sensing, predictive mobility, or traffic prediction, among other examples. In some examples, Al-as-a-Service use cases may include measurement collection reporting by a UE 120, device selection criteria (for example, according to a geographical area where measurements are to be collected or UE capabilities to be used to collected measurements), or reporting configurations (for example, reporting parameters such as location, time, or sensor information, among other examples). Additionally, or alternatively, the AI / ML model(s) may enable AI / ML procedures (for example, RAN-triggered service establishment, configuration, inferencing using UE-side or network-side models, performance monitoring or management, or capability signaling, among other examples). Additionally, or alternatively, the AI / ML model(s) may enable RAN-based AI / ML services via one or more application program interfaces (APIs) or management interfaces for use cases, such as beam management, radio resource monitoring (RRM) relaxation, mobility prediction, load prediction, network energy savings, or coverage and capacity improvements, among other examples).

[0050] In some aspects, the UE 120 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may transmit, to a network node 110, one or more capability reports associated with support for time interleaving for a multicast transport channel; and receive, from the network node 110, a configuration for the multicast transport channel in accordance with the one or more capability reports. The one or more capability reports may indicate support for at least a maximum scaled transport block size in accordance with an MCS and bandwidth, as described herein. Additionally, or alternatively, the communication manager 150 may perform one or more other operations described herein.0097-6179PCT

[0051] In some aspects, the network node 110 may include a communication manager 155. As described in more detail elsewhere herein, the communication manager 155 may receive, from a UE 120, one or more capability reports associated with UE support for time interleaving for a multicast transport channel; and transmit, to the UE 120, a configuration for the multicast transport channel in accordance with the one or more capability reports. The one or more capability reports may indicate support for at least a maximum scaled transport block size in accordance with an MCS and bandwidth, as described herein. Additionally, or alternatively, the communication manager 155 may perform one or more other operations described herein.

[0052] Fig. 2 is a diagram illustrating an example disaggregated network node architecture 200. One or more components of the example disaggregated network node architecture 200 may be, may include, or may be included in one or more network nodes (such one or more network nodes 110). The disaggregated network node architecture 200 may include a CU 210 that can communicate directly with a core network 220 via a backhaul link, or that can communicate indirectly with the core network 220 via one or more disaggregated control units, such as a non-real-time (Non-RT) RAN intelligent controller (RIC) 250 associated with a Service Management and Orchestration (SMO) Framework 260 or a near-real-time (Near-RT) RIC 270 (for example, via an E2 link). The CU 210 may communicate with one or more DUs 230 via respective midhaul links, such as via Fl interfaces. Each of the DUs 230 may communicate with one or more RUs 240 via respective fronthaul links. Each of the RUs 240 may communicate with one or more UEs 120 via respective RF access links. In some deployments, a UE 120 may be simultaneously served by multiple RUs 240.

[0053] Each of the components of the disaggregated network node architecture 200, including the CUs 210, the DUs 230, the RUs 240, the Near-RT RICs 270, the Non-RT RICs 250, and the SMO Framework 260, may include one or more interfaces or may be coupled with one or more interfaces for transmitting or receiving signals, such as data, control information, or reference signals via a wired or wireless transmission medium.

[0054] In some aspects, the CU 210 may be logically split into one or more CU user plane (CU-UP) units and one or more CU control plane (CU-CP) units. A CU-UP unit may communicate bidirectionally with a CU-CP unit via an interface, such as the El interface when implemented in an O-RAN configuration. The CU 210 may be deployed to communicate with one or more DUs 230, as necessary, for network control and signaling. Each DU 230 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 240. For example, a DU 230 may host various layers, such as an RLC layer, a MAC layer, or one or more PHY layers, such as one or more high PHY layers or one or more low PHY layers. Each layer (which also may be referred to as a module) may be implemented with an interface for communicating signals with other layers (and modules)0097-6179PCThosted by the DU 230, or for communicating signals with the control functions hosted by the CU 210. Each RU 240 may implement lower layer functionality. In some aspects, real-time and non-real-time aspects of control and user plane communication with the RU(s) 240 may be controlled by the corresponding DU 230.

[0055] The SMO Framework 260 may support RAN deployment and provisioning of nonvirtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 260 may support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operations and maintenance interface, such as an 01 interface. For virtualized network elements, the SMO Framework 260 may interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 290) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface, such as an 02 interface. A virtualized network element may include, but is not limited to, a CU 210, a DU 230, an RU 240, a non-RT RIC 250, or a Near-RT RIC 270. In some aspects, the SMO Framework 260 may communicate with a hardware aspect of a 4G RAN, a 5G NR RAN, or a 6G RAN, such as an open eNB (O-eNB) 280, via an 01 interface. Additionally, or alternatively, the SMO Framework 260 may communicate directly with each of one or more RUs 240 via a respective 01 interface. In some deployments, this configuration can enable each DU 230 and the CU 210 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0056] The Non-RT RIC 250 may include or may implement a logical function that enables non-real-time control and optimization of RAN elements and resources, AI / ME workflows including model training and updates, or policy-based guidance of applications or features in the Near-RT RIC 270. The Non-RT RIC 250 may be coupled to or may communicate with (such as via an Al interface) the Near-RT RIC 270. The Near-RT RIC 270 may include or may implement a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions via an interface (such as via an E2 interface) connecting one or more CUs 210, one or more DUs 230, or an O-eNB 280 with the Near-RT RIC 270.

[0057] In some aspects, to generate AI / ML models to be deployed in the Near-RT RIC 270, the Non-RT RIC 250 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 270 and may be received at the SMO Framework 260 or the Non-RT RIC 250 from non-network data sources or from network functions. In some examples, the Non-RT RIC 250 or the Near-RT RIC 270 may tune RAN behavior or performance. For example, the Non-RT RIC 250 may monitor long-term trends and patterns for performance and may employ AI / ML models to perform corrective actions via the0097-6179PCTSMO Framework 260 (such as reconfiguration via an 01 interface) or via creation of RAN management policies (such as Al interface policies).

[0058] The network node 110, the processing system 145 of the network node 110, the UE 120, the processing system 140 of the UE 120, the CU 210, the DU 230, the RU 240, or any other componcnt(s) of Fig. 1 or Fig. 2 may implement one or more techniques or perform one or more operations associated with time interleaving on a multicast transport channel, as described in more detail elsewhere herein. For example, the processing system 145 of the network node 110, the processing system 140 of the UE 120, the CU 210, the DU 230, or the RU 240 may perform or direct operations of, for example, process 600 of Fig. 6, or other processes as described herein (alone or in conjunction with one or more other processors). Memory of the network node 110 may store data and program code (or instructions) for the network node 110, the CU 210, the DU 230, or the RU 240. In some examples, the memory of the network node 110 may store data relating to a UE 120, such as RRC state information or a UE context.Memory of a UE 120 may store data and program code (or instructions) for the UE 120, such as context information. In some examples, the memory of the UE 120 or the memory of the network node 110 may include a non-transitory computer-readable medium storing a set of instructions for wireless communication. For example, the set of instructions, when executed by one or more processors (for example, of the processing system 145 or the processing system 140) of the network node 110, the UE 120, the CU 210, the DU 230, or the RU 240, may cause the one or more processors to perform process 600 of Fig. 6, or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, or interpreting the instructions, among other examples.

[0059] In some aspects, the UE 120 includes means for transmitting, to a network node 110, one or more capability reports associated with support for time interleaving for a multicast transport channel; and / or means for receiving, from the network node 110, a configuration for the multicast transport channel in accordance with the one or more capability reports. The one or more capability reports may indicate support for at least a maximum scaled transport block size in accordance with an MCS and bandwidth, as described herein. The means for the UE 120 to perform operations described herein may include, for example, one or more of communication manager 150, processing system 140, a radio, one or more RF chains, one or more transceivers, one or more antennas, one or more modems, a reception component (for example, reception component 702 depicted and described in connection with Fig. 7), or a transmission component (for example, transmission component 704 depicted and described in connection with Fig. 7), among other examples.0097-6179PCT

[0060] Figs. 3A and 3B are diagrams illustrating examples 300A and 300B, respectively, of redundancy version cycling. A network node (e.g., network node 110) may apply redundancy version cycling to time-interleaved multicast transport channel communications to transmit different redundancy versions of the communication in different transmission occasions.“Redundancy version” (RV) refers to a set of encoded bits that are transmitted for a transport block. Using RV cycling, the network node transmits a different set of encoded bits in different, non-contiguous slots of a multicast transport channel. A UE (e.g., UE 120) may store received redundancy versions in a circular buffer 305 (e.g., stored in memory of the UE 120).

[0061] In some aspects, the circular buffer 305 stores an output of a channel encoder as information bits 310 and parity bits 315 (sometimes called parity-check bits). The information bits 310 may include the data to be decoded, and the parity bits 315 may include linear combinations of the data (e.g., of the information bits 310). When the UE receives a sequence of encoded bits corresponding to one or more transport blocks, the UE may write the encoded bits sequentially into the circular buffer 305. The UE may use the circular buffer 305 to temporarily store the transport block and, using a de-interleaving process, reverse the interleaving that was applied at the transmitter (e.g., the network node). The de-interleaving process may include extracting bits from the circular buffer 305 in an order that counteracts the time interleaving performed during transmission. An outcome of the de-interleaving process may be the encoded transport block in its original order. The encoded transport block (e.g., which is a de-interleaved bit stream), including both information bits 310 and parity bits 315, may be provided to a channel decoder of the UE. The channel decoder may process the information bits and the parity bits to perform error correction and recover the original transport block.

[0062] In some aspects, the redundancy versions may be associated with a redundancy version starting pointer. In some aspects, the redundancy version starting pointer may be a parameter that indicates an initial offset in a circular buffer 305 from which encoded bits are read for a transport block. In some aspects, one or more redundancy version starting pointers may be adjusted to allow a different subset of an encoded bit stream to be selected for decoding. Accordingly, the redundancy version starting pointer may define, for each redundancy version, a starting position in the stored sequence of bits for de-interleaving and error correction processing.

[0063] In some aspects, starting bit locations for each redundancy version starting pointer may be defined by a table 340. The table 340 defines starting bit locations in the circular buffer 305 for a first base graph (BG1) and a second base graph (BG2). A base graph may be a parameter for determining parity bits 315 for a transmission based at least in part on a transport block size (TBS) and a code rate (with BG1 being intended for transport blocks with a larger0097-6179PCTTBS, and BG2 being intended for transport blocks with a smaller TBS). Referring to the table 340, Nbcbrepresents the length of the circular buffer 305 (e.g., the number of bits included in the circular buffer 305), and Zcrepresents a lifting size, which is associated with the number of information bits 310 and the number of BG columns corresponding to information bits 310.

[0064] In some aspects, a network node may transmit an RV index to the UE. For example, the network node may transmit the RV index via DCI, RRC signaling, or as a MAC-CE. The RV index may indicate a sequence of RVs to be applied to a corresponding sequence of communication occasions. The UE may increment a counter n (sometimes called an index n) for each communication occasion. The UE may use the RV index and the value of the counter n for a particular communication occasion to determine an RV to be applied to that communication occasion.

[0065] In some aspects, as shown by table 345 in Fig. 3 A, for PUSCH Repetition Type A, if the network node indicates an RV index of 0, then the UE 120 may determine an RV to be applied to an nth transmission occasion (e.g., for PUSCH Repetition Type A) by calculating n mod 4, where mod represents a modulo operation. If n mod 4 = 0 (e.g., for transmission occasion 0), then the UE may apply RV0 to that transmission occasion. If n mod 4 = 1 (e.g., for transmission occasion 1), then the UE may apply RV2 to that transmission occasion. If n mod 4 = 2 (e.g., for transmission occasion 2), then the UE may apply RV3 to that transmission occasion. If n mod 4 = 3 (e.g., for transmission occasion 3), then the UE may apply RV1 to that transmission occasion. In some aspects, the RV index may have a value of 0, 1, 2, or 3, each of which may correspond to a different sequence of RVs (e.g., a different order for RV0, RV1, RV2, and RV3).

[0066] Similarly, for PUSCH Repetition Type B, if the network node indicates an RV index of 0, then the UE may determine an RV to be applied to an nth actual repetition (e.g., of PUSCH Repetition Type B) by calculating n mod 4. If n mod 4 = 0 (e.g., for actual repetition 0), then the UE may apply RV0 to that actual repetition. If n mod 4 = 1 (e.g., for actual repetition 1), then the UE may apply RV2 to that actual repetition. If n mod 4 = 2 (e.g., for actual repetition 2), then the UE may apply RV3 to that actual repetition. If n mod 4 = 3 (e.g., for actual repetition 3), then the UE may apply RV1 to that actual repetition.

[0067] In some aspects, the UE may be configured with modified redundancy version starting pointers. As shown in the example 300B of Fig. 3B, the circular buffer 305 may be configured such that the redundancy version starting pointers allow the UE to store more redundancy versions (including, for example, a fourth redundancy version RV4350). In some aspects, as discussed below, the UE may be configured to indicate, to the network node, one or more capabilities associated with the circular buffer, a quantity of redundancy versions, or a0097-6179PCTcombination thereof, among other examples, associated with time interleaving for multicast transport channel communications.

[0068] As indicated above, Figs. 3A and 3B are provided as examples. Other examples may differ from what is described with respect to Figs. 3A and 3B.

[0069] Fig. 4 is a diagram illustrating an example 400 associated with transmitting redundancy versions of a transport block over non-contiguous slots, in accordance with the present disclosure. In the example 400 of Fig. 4, an original TBS 405 of a transport block may be scaled by a factor of n (which may be different from the transmission occasion value of n discussed above with respect to the example 300A of Fig. 3A). Redundancy versions of the n-scaled transport block may be transmitted over n non-contiguous slots. In some aspects, the redundancy versions may be transmitted in redundancy version slots 410 and other communications may be transmitted in data slots 415. In some aspects, for a transport block spread across m slots, one redundancy version slot 410 may occur for every m — 1 data slots 415. In some aspects, the value for m may be a quantity of parts of the transport block, a quantity of scaled TBSs, or a combination thereof, among other examples.

[0070] As discussed below, a UE may transmit one or more capability reports to a network node. The one or more capability reports may be associated with UE support for time interleaving for multicast transport channel communications. The UE support for time interleaving for multicast transport channel communications may correspond to a maximum decoder throughput, a total log-likelihood ratio (LLR) memory, or a combination thereof, among other examples. Accordingly, in some aspects, the UE may transmit the one or more capability reports to indicate a maximum TBS after scaling supported by the UE, a maximum soft buffer size, a maximum number of channel bits (e.g., coded bits) per transport block subframe that can be onloaded to the decoder, or a combination thereof, among other examples.

[0071] In some aspects, an input transport block may be scaled prior to segmentation and channel coding. In some aspects, the input transport block may be scaled to a valid (e.g., specification-compliant) TBS. In some aspects, the input transport block may be scaled to a TBS supported by a UE. For example, for a UE with 4-layer 256-QAM capabilities, a maximum number of bits of a downlink shared channel transport block received within a transmission time interval may be set in a specification as 195,816 bits. In accordance with an MCS and a bandwidth, the UE may select a scaling factor N. In some aspects, the UE may select the scaling factor N from a lookup table. In some aspects, the scaling factor N may also represent the quantity of redundancy versions for the scaled TBS. The UE may transmit the one or more capability reports to indicate the maximum scaled TBS supported by the UE, a category indication (e.g., UE-category-DL) that the network node may use to determine the maximum scaled TBS supported by the UE, or a combination thereof, among other examples. In some0097-6179PCTaspects, the network node may configure a time-interleaved transport block for the multicast transport channel in accordance with the maximum scaled TBS supported by the UE.

[0072] In some aspects, transmission of a transport block may require the UE to store multiple LLRs. In some aspects, the UE may be required to store an LLR for each redundancy version. Accordingly, the UE may be required to store M X N LLRs, where N is the scaling factor (e.g., the number of redundancy versions) and M is the number of scaled transport blocks. The UE may not be capable of storing M x N LLRs in a soft buffer. For example, the UE may not be capable of storing M X N LLRs in the soft buffer for different combinations of carrier aggregation, MCSs, and number of layers. Accordingly, for time interleaving, the UE may indicate, to the network node, the maximum number of coded bits across M X N transmissions spanning M transport blocks. For example, assuming a UE with 4-layer 256-QAM capabilities,304512,where NIRis the maximum soft buffer size for the incremental redundancy versions, NSOft is the soft buffer size of the UE, Kcis a quantity of bits in a code block, KMIM0is a quantity of MIMO layers, and MHARQ is a quantity of HARQ processes. The maximum soft buffer size for the maximum TBS may be.. FmaxTBS] .. F 195816 ]R,4L-256QAM -6144 24'Ncb —6144 24’ 9516 - 304512, with9516 and C = [max TBS] = 32,16144-241where Ncbis the quantity of coded bits for a code block (e.g., a bit-width) and C is the quantity of code blocks. In accordance with reuse of the soft buffer for time interleaving, the amount of memory available in the soft buffer may be split among the TBS, the scaling factor N. the number of scaled transport blocks M, the number of HARQ processes, the number of MIMO layers, and the number of component carriers for carrier aggregation (e.g., if concurrent with unicast communications). Accordingly, the UE may indicate a capability corresponding to the soft buffer size (e.g., a total number of soft channel bits) of the M x N subframes with LLRs to be stored by the UE for time -interleaved transmissions of M transport blocks across the M x N subframes. The network node may configure the time-interleaved communications for the multicast transport channel in accordance with the maximum soft buffer size indicated by the UE. For example, the network node may configure the UE with M transport blocks interleaved across M x N subframes having a total soft buffer size that does not exceed the total number of soft channel bits indicated by the UE.

[0073] In some aspects, the UE may have a maximum number of coded bits for a transport block. In some aspects, the UE may be configured or preconfigured (e.g., configured via0097-6179PCTfirmware) with the maximum number of coded bits for the transport block. In addition to the number of soft bits corresponding to the M x N subframes, discussed above, the UE may need to onload or offload the LLRs corresponding to the quantity of redundancy versions A of a transport block. In some aspects, for a unicast communication, the maximum number of LLRs for the UE to onload or offload, per transport block, with a single component carrier may be Ncbx C. As discussed above, Ncbis the quantity of coded bits for a code block (e.g., a bitwidth) and C is the quantity of code blocks. For a TBS of 195,816 bits and 32 code blocks (e.g., C = 32), the number of LLRs to be onloaded or offloaded may be 304,512. For a multicast transport channel communication, the UE may be required to onload or offload a greater quantity of LLRs. For example, for each of the M transport blocks in a multicast transport channel communication,Ncb= KW= 3Kn,where Kwand Knare parameters associated with a quantity of bits for the LLRs. Accordingly, for multicast transport channel communications with a TBS of 195,816 bits and 32 code blocks, the UE may be expected to onload or offload approximately 600,000 LLRs for each of the M transport blocks, which may exceed the capabilities of the UE, which may limit how many downlink shared channel unicast communications the UE may receive, the quantity of transport blocks that can be interleaved, or a combination thereof, among other examples. In some aspects, the network node may configure time interleaving for the multicast transport channel communications in accordance with the maximum number of coded bits for a transport block supported by the UE. For example, in some aspects, the network node may be configured to limit, and the UE may be configured to apply, the quantity of coded bits Ncbfor multicast transport channel communications in accordance withfor transport blocks containing multicast transport channel data on the multicast transport channel, where NIRis a total or maximum soft buffer size for a transport block. In some aspects, the network node may indicate, to the UE, that the physical multicast channel symbols carrying the multicast transport channel data are time -interleaved. Alternatively, in some aspects, the network node may be configured to limit, or the UE may be configured to apply, the quantity of coded bits Ncbfor multicast transport channel communications in accordance withMbiorz>2=Mv- F°rexample, in some aspects, the UE may apply the equation for Ncblor the equation for Ncb2to determine the maximum number of coded bits for the transport block in accordance with a TBS threshold. In some aspects, the TBS threshold may be one-half (e.g.,0097-6179PCTK 1KC 2 of a maximum allowable TBS corresponding to a UE category. In some aspects, the UE may apply the equation for lVcblwhen the TBS satisfies the TBS threshold. In some aspects, the UE may apply the equation for / Vcb2when the TBS does not satisfy the TBS threshold.

[0076] As shown by reference number 505, the UE 120 may transmit, and the network node 110 may receive, one or more capability reports associated with UE support for time interleaving for a multicast transport channel.

In some aspects, the one or more capability reports may directly or indirectly indicate a quantity of supported redundancy versions.

[0077] Alternatively or in addition, in some aspects, the one or more capability reports may indicate UE support for a maximum quantity of coded bits in accordance with a quantity of supported redundancy versions and a quantity of scaled transport block sizes, as discussed above with respect to Fig. 4. In some aspects, the maximum quantity of coded bits may be a quantity of coded bits corresponding to a quantity of transmissions over a quantity of scaled transport blocks. In some aspects, the quantity of transmissions may be a function of the quantity of scaled TBSs, a size of the scaled TBSs, and a quantity of redundancy versions, as discussed above with respect to Fig. 4.

[0078] Alternatively or in addition, in some aspects, the one or more capability reports may indicate UE support corresponding to a total quantity of soft channel bits that correspond to a buffer memory size.

[0079] Alternatively or in addition, in some aspects, the one or more capability reports may indicate UE support for a quantity of LLRs corresponding to a quantity of redundancy versions of a transport block.

In some aspects, the quantity of LLRs may be associated with a quantity of coded bits within a single code block and a quantity of code blocks, as discussed above with respect to Fig. 4. In some aspects, the quantity of coded bits within the single code block may be a function of one or more of a maximum number of supported LLRs, a soft buffer capacity, or the quantity of code blocks. In some aspects, the quantity of coded bits within the single code block may be associated with a TBS threshold. For example, as discussed above with respect to Fig. 4, the quantity of coded bits may include one of a first quantity of coded bits corresponding to a TBS that satisfies the TBS threshold or a second quantity of coded bits corresponding to a TBS that does not satisfy the TBS threshold. In some aspects, as discussed above with respect to Fig. 4, the TBS threshold may be one-half of a maximum allowable TBS.

[0080] As shown by reference number 510, the network node 110 may transmit, and the UE 120 may receive, a configuration for time interleaving on the multicast transport channel in accordance with the one or more capability reports. In some aspects, the configuration for the multicast transport channel may configure the UE 120 to receive, store, and decode redundancy versions of a transport block in accordance with one or more TBSs supported by the UE 120.

[0081] As shown by reference number 515, the UE 120 may apply the configuration for time interleaving on the multicast transport channel. In some aspects, the UE 120 may apply one or more parameters corresponding to the configuration for time interleaving on the multicast transport channel. For example, the configuration for time interleaving on the multicast transport channel may configure a TBS with one or more parameters that may allow the UE 120 to receive a redundancy version, store the redundancy version in a circular buffer, and decode the redundancy version without exceeding the capabilities of the UE 120.

[0082] As shown by reference number 520, the network node 110 may transmit, and the UE 120 may receive, communications on the multicast transport channel. In some aspects, the communications transmitted on the multicast transport channel may be time-interleaved in accordance with the configuration for time interleaving on a multicast transport channel.
