Background Technology

[0002] The following discussion relates to wireless communications, including enhanced external decoding for broadcast communications.

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Aspects of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each supporting wireless communication for communication devices, which may be referred to as User Equipment (UE). Summary of the Invention

[0004] The described techniques relate to improved methods, systems, devices, and apparatuses supporting enhanced external decoding for broadcast communications. For example, the described techniques provide enhanced application-layer external decoding, physical or MAC-layer external decoding, or both, which can improve reliability in broadcast transmission.

Alternatively, the network entity can map each MAC PDU to a single code block of the corresponding TB and broadcast that TB via a single timeslot. In some other aspects, the network entity can perform physical or MAC-layer external encoding on application-layer packets, wherein the network entity can perform external encoding on multiple MAC Service Data Units (SDUs) to generate externally encoded MAC PDUs.

[0087] Figures 13 to 24 A flowchart illustrating a method for enhanced external decoding for broadcast communications, according to one or more aspects of this disclosure, is shown. Detailed Implementation

[0088] In some wireless communication systems, network entities can perform broadcast communication, whereby, to facilitate such communication, the network entity can implement a communication protocol stack. For example, the network entity can generate application-layer packets at the application layer of the protocol stack, which can be mapped to MAC Packet Data Units (PDUs) at the Media Access Control (MAC) layer of the protocol stack. The network entity can map MAC PDUs to individual code blocks of a Transport Block (TB) and subsequently broadcast the TB at the physical layer of the protocol stack.

[0089] To increase the reliability of broadcast transmission, network entities can perform application-layer external decoding. For example, at the application layer, the network entity can use external codes to encode a combination of multiple application-layer packets. Subsequently, at the physical layer, the network entity can use internal codes (such as low-density parity-check codes (LDPC) or Turbo codes) to encode multiple TBs, each of which is associated with a corresponding application-layer packet. This internal decoding can be called channel decoding.

[0090] However, in such cases, the flexibility of such external coding may prevent the receiver of a broadcast transmission from identifying various failed code blocks within one or more TBs. That is, because external coding is performed at the application layer rather than at the physical or MAC layer, the receiver may be able to determine which of multiple application layer packets have failed (e.g., at the application layer) based on application layer external decoding, but may not be able to identify and correct (e.g., at the physical or MAC layer) failed code blocks within a single TB, which could lead to reduced communication reliability in broadcast transmissions.

[0091] The techniques, methods, and apparatus described herein can provide implementations of, or enhancements to, application-layer out-of-code, physical or MAC-layer out-of-code to provide increased granularity of out-of-code. In some aspects, network entities (e.g., broadcasters or transmitters) can implement various enhancements to application-layer out-of-code to improve broadcast performance. Network entities can encode multiple application-layer packets at the application layer using application-layer out-of-code to generate out-of-code application-layer packets. Based on applying out-of-code to the application-layer packets, network entities can generate multiple MAC PDUs, each associated with a corresponding application-layer packet in the out-of-code application-layer packets. In such aspects, each MAC PDU may correspond to a single code block in size (in bits).

[0092] In one aspect, a network entity may map each MAC PDU in a MAC PDU to a single code block of the corresponding TB and broadcast each of the multiple TBs in a first timeslot. In another aspect, a network entity may map each MAC PDU in a MAC PDU to a corresponding code block of a single TB and broadcast that single TB. In this way, because each MAC PDU (and its associated application layer packet) is mapped to a single code block, the receiver of the broadcast transmission can be able to identify and correct errors in the broadcast transmission at the code block level using an application layer-outside decoder.

[0093] In some other respects, network entities can implement physical layer or MAC layer external decoding to improve the performance and reliability of broadcast transmissions. For example, a network entity can generate multiple MAC PDUs, each associated with a corresponding application layer packet. In response to generating MAC PDUs, the network entity can concatenate multiple MAC PDUs, encode the concatenated MAC PDUs using an external code (e.g., such as Raptor code, RaptorQ code, etc.) to generate parity bits, and then append the concatenated MAC PDUs with the parity bits to generate an externally encoded MAC PDU.

[0094] In response to the generation of an externally encoded MAC PDU, the network entity can segment the externally encoded MAC PDU into multiple TBs and broadcast each of the multiple TBs via the corresponding time slots. In this way, because the parity bits correspond to the code blocks of the MAC PDU, the receiver broadcasting the PDU can identify and correct failed code blocks within the transmission of the multiple MAC PDUs.

[0095] The aspects of this disclosure are initially described in the context of a wireless communication system. The aspects of this disclosure are then described in the context of a protocol stack, resource diagram, and process flow. The aspects of this disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flowcharts relating to enhanced external decoding for broadcast communications.

[0096] Figure 1 Aspects of a wireless communication system 100 supporting enhanced external decoding for broadcast communications, according to one or more aspects of this disclosure, are illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some aspects, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating according to other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0097] Network entity 105 may be distributed across a geographical area to form wireless communication system 100, and may include devices of different forms or with different capabilities. In various aspects, network entity 105 may be referred to as a network element, mobility element, radio access network (RAN) node, or network equipment, etc. In some aspects, network entity 105 and UE 115 may wirelessly communicate via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, network entity 105 may support coverage area 110 (e.g., a geographical coverage area) within which UE 115 and network entity 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographical area within which network entity 105 and UE 115 may support the transmission of signals according to one or more radio access technologies (RATs).

[0098] UE 115 can be distributed throughout the coverage area 110 of wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be devices in different forms or with different capabilities. Figure 1 Some example UE 115s are illustrated herein. The UE 115 described herein can be able to support various types of devices (such as, e.g., ...). Figure 1 It communicates with other UEs (115 or network entity 105) as shown.

[0099] As described herein, a network entity (which may alternatively be referred to as an entity, node, network node, or wireless entity) can be, can be similar to, can include, or can be included in (e.g., can be a component of) the following: base station (e.g., any base station described herein, including a decomposed base station), UE (e.g., any UE described herein), RedCap device, eRedCap device, environmental Internet of Things (IoT) device, energy harvesting (EH) capable device, network controller, apparatus, device, computing system, integrated access and backhaul (IAB) node, distributed unit (DU), central unit (CU), remote / radio unit (RU) (which may also be referred to as a remote radio unit (RRU)), and / or another processing entity configured to perform any of the techniques described herein. For example, a network entity can be a UE. As another example, a network entity can be a base station. As used herein, “network entity” can mean an entity configured to operate in a network (such as wireless communication system 100). For example, “network entity” is not limited to entities currently located in and / or currently operating in a network. Rather, a network entity can be any entity capable of communicating and / or operating within a network.

[0100] The adjectives "first," "second," "third," etc., are used to distinguish between two or more modified nouns in context, and do not imply absolute modifiers applicable only to a specific corresponding entity throughout the document. For example, a network entity may be referred to as "first network entity" in one discussion and as "second network entity" in another, and vice versa. As an example, the first network entity may be configured to communicate with a second network entity or a third network entity. In one aspect of this example, the first network entity may be a UE, the second network entity may be a base station, and the third network entity may be a UE. In another aspect of this example, the first network entity may be a UE, the second network entity may be a base station, and the third network entity may be a base station. In yet other aspects of this example, the first, second, and third network entities may be different from these examples.

[0101] Similarly, references to UE, base station, device, equipment, computing system, etc., may include disclosures of UE, base station, device, equipment, computing system, etc., as network entities. For example, a disclosure of a UE being configured to receive information from a base station also discloses that a first network entity is configured to receive information from a second network entity. Consistent with this disclosure, once a particular example is extended according to this disclosure (e.g., a disclosure of a UE being configured to receive information from a base station also discloses that a first network entity is configured to receive information from a second network entity), a broader example of a narrower example may be interpreted in reverse, but in a broad, open-ended manner. In the above example where a UE is configured to receive information from a base station and a first network entity is configured to receive information from a second network entity, the first network entity may refer to a first UE, a first base station, a first device, a first equipment, a first computing system, a first set of one or more components, a first processing entity, etc., configured to receive information; and the second network entity may refer to a second UE, a second base station, a second device, a second equipment, a second computing system, a second set of one or more components, a second processing entity, etc.

[0102] As described herein, different terms may be used in various contexts to describe the transmission of information (e.g., any information, signal, etc.). Disclosure of one communication term includes disclosure of other communication terms. For example, a first network entity may be described as being configured to send information to a second network entity. In this example and consistent with this disclosure, disclosure that a first network entity is configured to send information to a second network entity includes disclosure that the first network entity is configured to provide, transmit, output, communicate, or send information to the second network entity. Similarly, in this example and consistent with this disclosure, disclosure that a first network entity is configured to send information to a second network entity includes disclosure that the second network entity is configured to receive, obtain, or decode information provided, transmitted, output, communicate, or sent by the first network entity.

[0103] As shown in the figure, a network entity (e.g., network entity 105) may include a processing system 106. Similarly, a network entity (e.g., UE 115) may include a processing system 112. A processing system may include one or more components (or sub-components), such as those described herein. For example, a corresponding component among these one or more components may be, similar to, include, or be included in at least one memory, at least one communication interface, or at least one processor. For example, a processing system may include one or more components. In such an example, the one or more components may include a first component, a second component, and a third component. In this example, the first component may be coupled to the second and third components. In this example, the first component may be at least one processor, the second component may be a communication interface, and the third component may be at least one memory. A processing system is generally one or more components of a system capable of performing one or more functions (such as any function or combination of functions described herein). For example, one or more components may receive input information (e.g., any information as input, such as a signal, any digital information, or any other information), one or more components may process the input information to generate output information (e.g., any information as output, such as a signal or any other information), one or more components may perform any function as described herein or any combination thereof. As described herein, “input” and “input information” can be used interchangeably. Similarly, as described herein, “output” and “output information” can be used interchangeably. Any information generated by any component can be provided to one or more other systems or components of network entities such as those described herein. For example, a processing system may include a first component configured to receive or obtain information, a second component configured to process the information to generate output information, and / or a third component configured to provide the output information to other systems or components. In this example, the first component may be a communication interface (e.g., a first communication interface), the second component may be at least one processor (e.g., coupled to the communication interface and / or at least one memory), and the third component may be a communication interface (e.g., a first communication interface or a second communication interface). For example, a processing system may include at least one memory, at least one communication interface, and / or at least one processor, wherein the at least one processor may, for example, be coupled to the at least one memory and the at least one communication interface.

[0104] The processing system of the network entity described herein can interface with one or more other components of the network entity, process information received from one or more other components (such as input information), or output such information to one or more other components. For example, the processing system may include a first component configured to interface with one or more other components of the network entity to receive or obtain information, a second component configured to process the information to generate one or more outputs, and / or a third component configured to output the one or more outputs to one or more other components. In this example, the first component may be a communication interface (e.g., a first communication interface), the second component may be at least one processor (e.g., coupled to the communication interface and / or at least one memory), and the third component may be a communication interface (e.g., the first communication interface or the second communication interface). For example, a chip or modem of the network entity may include the processing system. The processing system may include a first communication interface for receiving or obtaining information, and a second communication interface for outputting, transmitting, or providing information. In some examples, the first communication interface may be an interface configured to receive input information, and such information may be provided to the processing system. In some examples, the second system interface may be configured to transmit information output from the chip or modem. The second communication interface can also obtain or receive input information, and the first communication interface can also output, send, or provide information.

[0105] In some aspects, network entity 105 may communicate with core network 130, communicate with each other, or both. For example, network entity 105 may communicate with core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some aspects, network entities 105 may communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some aspects, network entities 105 may communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. Backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), and other aspects or various combinations thereof. UE 115 can communicate with core network 130 via communication link 155.

[0106] One or more network entities in network entity 105 described herein may include or be referred to as base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, node B, eNodeB (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home node B, home evolution node B, or other suitable terms). In some aspects, network entity 105 (e.g., base station 140) may be implemented in an aggregated (e.g., monolithic, self-contained) base station architecture that may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as base station 140).

[0107] In some aspects, network entity 105 may be implemented in a decomposed architecture (e.g., a decomposed base station architecture, a decomposed RAN architecture) that can be configured to utilize a protocol stack physically or logically distributed among two or more network entities 105 (such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN))). For example, network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. RU 170 may also be referred to as a radio headend, an intelligent radio headend, a remote radio headend (RRH), a remote radio unit (RRU), or a transmit-receive point (TRP). One or more components of network entity 105 in a decomposed RAN architecture may be co-located, or one or more components of network entity 105 may be located in distributed locations (e.g., separate physical locations). In some aspects, one or more network entities 105 in a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0108] The functional splitting among CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a protocol stack functional splitting can be used between CU 160 and DU 165, allowing CU 160 to support one or more layers of the protocol stack, and DU 165 to support one or more different layers of the protocol stack. In some respects, CU 160 can host higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionalities and signaling (e.g., Radio Resource Control (RRC), Service Data Adaptation Protocol, Packet Data Convergence Protocol). CU 160 can connect to one or more DU 165 or RU 170, and these DU 165 or RU 170 can host lower protocol layers, such as Layer 1 (L1) (e.g., physical layer) or L2 (e.g., radio link control layer, MAC layer) functionality and signaling, and can each be at least partially controlled by CU 160. Additionally or alternatively, protocol stack functional splitting can be employed between DU 165 and RU 170, such that DU 165 can support one or more layers of the protocol stack, and RU 170 can support one or more different layers of the protocol stack. DU 165 can support one or more different cells (e.g., via one or more RU 170). In some cases, functional decomposition between CU 160 and DU 165, or between DU 165 and RU 170, can be performed within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer can be performed by different of CU 160, DU 165, or RU 170). CU 160 can be further functionally decomposed into CU control plane (CU-CP) functions and CU user plane (CU-UP) functions. CU 160 can be connected to one or more DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to one or more RU 170 via fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some respects, the midhaul communication link 162 or the fronthaul communication link 168 may be implemented based on the interfaces (e.g., channels) between the layers of the protocol stack, each layer of which is supported by the corresponding network entity 105 communicating via such communication links.

[0109] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access can support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB node 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DU 165s or one or more RU 170s may be partially controlled by one or more CU 160s associated with donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB node 104) via supported access and backhaul links (e.g., backhaul communication link 120). IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB donor. The IAB-MT may include a separate set of antennas for relaying communication with UE 115, or may share the same antennas (e.g., those of RU 170) for access to IAB node 104 via DU 165 of IAB node 104. (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some aspects, IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of IAB node 104) may be configured to operate according to the techniques described herein.

[0110] In the context of applying the techniques described herein to a decomposed RAN architecture, one or more components of the decomposed RAN architecture can be configured to support enhanced external decoding for broadcast communications as described herein. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).

[0111] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some aspects, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, which may be implemented in appliances or vehicles, meters, etc.

[0112] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes act as repeaters, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 As shown in the image.

[0113] UE 115 and network entity 105 can wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" can refer to a set of RF spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the RF spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating carrier operation, user data, or other signaling. Wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 may be configured to utilize multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers. Communication between network entity 105 and other devices can refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms “send,” “receive,” or “communicate” when referring to network entity 105 can refer to any part of the RAN’s network entity 105 (e.g., base station 140, CU160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities 105).

[0114] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high modulation scheme order correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0115] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period. seconds, in response This can represent the supported subcarrier spacing, while The supported Discrete Fourier Transform (DFT) size can be represented. Time intervals for communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0116] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some aspects, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., The duration of a symbol period is associated with a (number) sampling period. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0117] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some aspects, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst form of a shortened TTI (sTTI)).

[0118] Depending on the technology, carriers can be used to multiplex physical channels for communication. One or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used, for example, to multiplex physical control channels and physical data channels for signaling via a downlink carrier. The control region (e.g., control resource set (CORESET)) of the physical control channel can be defined by a set of symbol periods and can extend across the system bandwidth of the carrier or a subset of that bandwidth. One or more control regions (e.g., CORESET) can be configured for a set of UEs 115. For example, one or more UEs in UE 115 can monitor or search for control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a concatenated manner. The aggregation level of control channel candidates can refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set may include: a common search space set configured to transmit control information to multiple UEs 115, and a UE-specific search space set used to transmit control information to a specific UE 115.

[0119] In some aspects, network entity 105 (e.g., base station 140, RU 170) may be mobile, and thus provide communication coverage to mobile coverage areas 110. In some aspects, while different coverage areas 110 associated with different technologies may overlap, different coverage areas 110 may be supported by the same network entity 105. In some other aspects, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0120] Wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communication may include private or group communication and may be supported by one or more services, such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritizing services, and such services may be used for public safety or general business applications. The terms “ultra-reliable,” “low-latency,” and “ultra-reliable low-latency” are used interchangeably herein.

[0121] In some aspects, UE 115 may be configured to support direct communication with other UE 115s via device-to-device (D2D) communication link 135 (e.g., according to peer-to-peer (P2P), D2D, or sidelink protocols). In some aspects, one or more UEs 115s performing D2D communication in a group may be within the coverage area 110 of network entity 105 (e.g., base station 140, RU 170), which may support aspects of such D2D communication configured (e.g., scheduled) by network entity 105. In some aspects, one or more UEs 115s in such a group may be outside the coverage area 110 of network entity 105, or may otherwise be unable or not configured to receive transmissions from network entity 105. In some aspects, the group of UEs 115s communicating via D2D communication may support a one-to-many (1:M) system, wherein each UE 115 transmits to every other UE 115 in the group. In some respects, network entity 105 can facilitate the scheduling of resources for D2D communication. In other respects, D2D communication can be performed between UEs 115 without involving network entity 105.

[0122] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a Mobility Management Entity (MME), Access and Mobility Management Function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)) for routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by network entity 105 (e.g., base station 140) associated with core network 130. User IP packets can be delivered through the user plane entity, which provides IP address allocation and other functions. The user plane entity may connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0123] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the region from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range is approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves are sufficient to penetrate structures so that macrocells can provide service to UE 115 located indoors. Compared to communication using smaller frequencies and longer wavelengths in the lower frequencies (HF) or very high frequencies (VHF) portions of the spectrum below 300 MHz, communication using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0124] Wireless communication system 100 can utilize both licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology using unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating using unlicensed RF spectrum, devices such as network entity 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some aspects, operation using unlicensed frequency bands may be combined with component carriers operating using licensed frequency bands based on carrier aggregation configurations (e.g., LAA). Operations using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0125] Network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some aspects, the antennas or antenna arrays associated with network entity 105 may be located at different geographical locations. Network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that network entity 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0126] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., network entity 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating along a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of these antenna elements may be defined by a beamforming weight set associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device or relative to some other orientation).

[0127] Network entity 105 can perform broadcast communication, wherein, to facilitate such communication, network entity 105 can implement a communication protocol stack. For example, network entity 105 can generate application layer packets at the application layer of the protocol stack, which can be mapped to MAC PDUs at the MAC layer of the protocol stack. Network entity 105 can map MAC PDUs to individual code blocks of a TB and then broadcast the TB at the physical layer of the protocol stack.

[0128] To increase the reliability of broadcast transmission, network entity 105 may perform application-layer external decoding. For example, at the application layer, network entity 105 may encode a combination of multiple application-layer packets using external codes. Subsequently, at the physical layer, network entity 105 may encode multiple TBs using internal codes such as LDPC or Turbo codes, each of which is associated with a corresponding application-layer packet. This internal decoding may be referred to as channel decoding.

[0129] However, in such cases, the flexibility of such external coding may prevent the receiver of a broadcast transmission from identifying various failed code blocks within one or more TBs. That is, because external coding is performed at the application layer rather than at the physical or MAC layer, the receiver may be able to determine which of multiple application layer packets have failed (e.g., at the application layer) based on application layer external decoding, but may not be able to identify and correct (e.g., at the physical or MAC layer) failed code blocks within a single TB, which could lead to reduced communication reliability in broadcast transmissions.

[0130] The techniques, methods, and apparatus described herein can provide implementations or enhancements to application-layer out-of-code, physical or MAC-layer out-of-code, to provide increased granularity of out-of-code. In some aspects, network entity 105 (e.g., a broadcaster or sender) can implement various enhancements to application-layer out-of-code to improve the performance of broadcast transmission. Network entity 105 can encode multiple application-layer packets at the application layer using application-layer out-of-code to generate out-of-code application-layer packets. Based on applying out-of-code to the application-layer packets, network entity 105 can generate multiple MAC PDUs, each associated with a corresponding application-layer packet in the out-of-code application-layer packets. In such aspects, each MAC PDU may correspond to a single code block in size (in bits).

[0131] In one aspect, network entity 105 may map each MAC PDU in a MAC PDU to a single code block of the corresponding TB, and broadcast each of the multiple TBs in a first timeslot. In another aspect, network entity 105 may map each MAC PDU in a MAC PDU to a corresponding code block of a single TB, and broadcast that single TB. In this way, because each MAC PDU in a MAC PDU (e.g., and the associated application layer packet) is mapped to a single code block, the receiver of the broadcast transmission can be able to identify and correct errors in the broadcast transmission at the code block level using an application layer off-decoder.

[0132] In some other aspects, network entity 105 may implement physical layer or MAC layer external decoding to improve the performance and reliability of broadcast transmission. For example, network entity 105 may generate multiple MAC PDUs, each associated with a corresponding application layer packet. In response to generating MAC PDUs, network entity 105 may concatenate multiple MAC PDUs, encode the concatenated MAC PDUs using an external code (e.g., such as Raptor code, RaptorQ code, etc.) to generate parity bits, and then append the concatenated MAC PDUs with the parity bits to generate an externally encoded MAC PDU.

[0133] In response to generating an externally encoded MAC PDU, network entity 105 can segment the externally encoded MAC PDU into multiple TBs and broadcast each of the multiple TBs via corresponding time slots. In this way, because parity bits correspond to code blocks of the MAC PDU, the receiver broadcasting the PDU can identify and correct failed code blocks within the transmission of the multiple MAC PDUs.

[0134] Figure 2Aspects of a wireless communication system 200 supporting enhanced external decoding for broadcast communications, according to one or more aspects of this disclosure, are shown. The aspects of the wireless communication system 200 can be implemented as referenced herein. Figure 1 The described aspects of the wireless communication system 100, or aspects thereof, may be implemented by these aspects. For example, the wireless communication system 200 may include network entity 105-a (e.g., a broadcaster) and network entity 105-b (e.g., a receiver), which may be aspects of network entity 105 as described herein. The techniques described in the context of the wireless communication system 200 enable network entity 105-a to increase the reliability of 5G broadcast communications by implementing enhanced external decoding techniques.

[0135] To facilitate broadcast communication, network entity 105-a may implement protocol stack 205. For example, network entity 105-a may generate application layer packets 210 containing data to be broadcast at the application layer. In such an example, application layer packet 210 may be an example of an Internet Protocol (IP) packet (and other types of information). Based on the generated application layer packet 210, network entity 105-a may forward the application layer packet 210 to the Service Data Adaptation Protocol (SDAP) layer. At the SDAP layer, network entity 105-a may encode the application layer packet 210 (which may be referred to as SDAP Service Data Unit (SDU) 215) to generate an SDU header (e.g., H), and concatenate the SDAP SDU 215 with the header to generate an SDAP Packet Data Unit (PDU). As used herein, PDU and SDU can be used in a general sense to identify units of application layer packets at each layer of protocol stack 205, including units with headers. Such definitions of PDU and SDU are not limited by the current naming conventions or by previous references to the same terms.

[0136] Network entity 105-a can forward SDAP PDUs to the Packet Data Convergence Protocol (PDCP) layer, where it can encode the SDAP PDU (also known as PDCP SDU 220) to generate a PDCP header and concatenate the PDCP SDU 220 with the header to generate a PDCP PDU. Network entity 105-a can forward PDCP PDUs to the Radio Link Control (RLC) layer, encode the PDCP PDU (also known as RLC SDU 225) to generate an RLC header, and concatenate the RLC SDU 225 with the header to generate an RLC PDU. Network entity 105-a can forward RLC PDUs to the MAC layer, where it can encode the RLC PDU (also known as MAC SDU 230) to generate a MAC header and concatenate the MAC SDU 230 with the header to generate a MAC PDU 235.

[0137] In response to the generation of MAC PDU 235, network entity 105-a may map MAC PDU 235 to multiple code blocks within TB 240 at the physical layer of the network entity, encode TB using internal codes such as LDPC or turbo codes, map TB 240 to time slots (e.g., time slots) and frequency resources, and broadcast TB 240. Network entity 105-b may receive TB 240 and continue to decode TB 240 at the physical layer to obtain MAC PDU 235, and send MAC PDU 235 to the MAC layer of network entity 105-b.

[0138] At the MAC layer, network entity 105-b can use the MAC header to decode MAC PDU 235 to obtain MAC SDU 230 (e.g., RLC PDU), and forward MAC SDU 230 to the RLC layer. At the RLC layer, network entity 105-b can use the RLC header to decode MAC SDU 230 to obtain RLC SDU 225 (e.g., PDCP PDU), and forward RLC SDU 225 to the PDCP layer. Network entity 105-b can use the PDCP header to decode RLC SDU 225 to obtain PDCP SDU 220 (e.g., SDAP PDU), and forward PDCP SDU 220 to the SDAP layer. At the SDAP layer, network entity 105-b can use the SDAP header to decode PDCP SDU 220 to obtain SDAP SDU 215 (e.g., application layer packet 210), and forward SDAP SDU 215 to the application layer. At the application layer, network entity 105-b can decode application layer packets 210 to obtain broadcast data. In this way, network entities 105-a and 105-b can use protocol stack 205 to perform broadcast communication.

[0139] To improve the reliability of broadcast communications, network entity 105-a can perform external decoding. As described herein, the external code can be an example of an auxiliary or supplementary error-correcting code (ECC) applied to the data before the internal code (e.g., the primary ECC code), such that the internal code is decoded first before the externally encoded data is decoded. By using external decoding, network entity 105-a can achieve near-error-free (QEF) broadcast transmission.

[0140] Using current 5G terrestrial broadcast technology, network entity 105-a can support application layer out-of-layer decoding; however, the flexibility of current application layer out-of-layer decoding may be limited compared to other technologies. For example, network entity 105-a can use an out-of-layer code to encode a combination of multiple application layer packets 210, allowing the out-of-layer code to operate across multiple application layer packets 210. Subsequently, at the physical layer, network entity 105-a can use an inner code to encode multiple TBs 240. However, in such cases, the flexibility of this out-of-layer code may not allow the receiver of the broadcast transmission to identify various failed code blocks within one or more TBs 240.

[0141] That is, if network entity 105-a broadcasts multiple TBs 240, each containing multiple code blocks (e.g., each encapsulating a corresponding application layer packet 210), then network entity 105-b (e.g., the receiver) may not be able to utilize block-level cyclic redundancy check (CRC). For example, because external encoding is performed at the application layer level rather than at the physical or MAC layer, network entity 105-b may only be able to determine which application layer packets 210 have failed, and cannot identify and correct which code blocks in each TB 240 (e.g., carrying the corresponding application layer packet 210) have failed, which could lead to reduced communication reliability during broadcast transmission. Therefore, in such a scenario, network entity 105-b may not be able to identify and correct which code blocks carrying data associated with the application layer packet 210 have failed, thus making it impossible to decode the application layer packet 210.

[0142] To utilize block-level CRC for broadcast transmission, physical or MAC layer out-of-layer (PLE) coding can be implemented. However, using current 5G terrestrial broadcast technologies (e.g., those outlined in the 3GPP standard), network entity 105-a may not support PLE or MAC layer out-of-layer decoding, thus preventing network entity 105-a from performing broadcast communication during QEF transmission (e.g., one packet error per hour). That is, due to the relatively low physical block error rate (BLER) required for QEF transmission, network entity 105-a may not be able to achieve QEF transmission using a single decoding technique such as Turbo or LDPC codes or current application layer out-of-layer (ALE) coding techniques. Therefore, it is expected that network entity 105-a will implement enhanced application layer out-of-layer (ALE) decoding techniques, implement PLE or MAC layer out-of-layer (ALE) decoding, or both, to utilize block-level CRC.

[0143] According to the techniques described herein, network entity 105-a may implement physical layer or MAC layer out-of-line decoding, implement enhancements to application layer out-of-line decoding (e.g., modified versions), or both, to utilize block-level CRC. In some aspects, network entity 105-a may implement various enhancements to application layer out-of-line decoding to improve the performance of broadcast transmission.

[0144] For example, network entity 105-a may encode multiple application layer packets 210 at the application layer using application layer foreign codes to generate foreign-coded application layer packets. Based on the application of foreign codes to application layer packets 210, network entity 105-a may generate multiple MAC PDUs 235, each of which is associated with a corresponding application layer packet 210 in the foreign-coded application layer packets, wherein each MAC PDU 235 corresponds in size to a single corresponding code block. That is, each MAC PDU 235 may include a number of bits equal to a predefined code block size (in bits). In one aspect, network entity 105-a may map each MAC PDU 235 to a single code block of a corresponding TB 240 and broadcast each of the multiple TBs 240 in a first timeslot (e.g., the multiple TBs 240 are broadcast in a single timeslot). On the other hand, network entity 105-a can map each MAC PDU 235 to a corresponding code block of a single TB 240 and broadcast that single TB 240. In this way, because each MAC PDU 235 (e.g., and the corresponding application layer packet 210) corresponds to a single code block, network entity 105-b can decode the broadcast transmission and identify errors in the broadcast transmission at the code block level. Techniques for enhancing application layer out-of-layer coding are referenced herein. Figure 3 and Figure 4 Further description.

[0145] Additionally or alternatively, network entity 105-a may implement physical layer or MAC layer external decoding to improve the performance and reliability of broadcast transmission. For example, network entity 105-a may generate multiple MAC PDUs 235, each MAC PDU 235 being associated with a corresponding application layer packet 210. In response to generating MAC PDUs 235, network entity 105-a may concatenate multiple MAC PDUs 235, encode the concatenated MAC PDUs 235 using an external code (e.g., such as Raptor code, RaptorQ code, etc.) to generate a parity bit, and then append the concatenated MAC PDUs 235 with the parity bit to generate an externally encoded MAC PDU. In response to generating the externally encoded MAC PDU, network entity 105-a may segment the externally encoded MAC PDU into multiple TBs 240, and broadcast each of the multiple TBs 240 via corresponding time slots. In this way, because the parity bit corresponds to the code block of MAC PDU 235, network entity 105-b can identify and correct failed code blocks when decoding multiple MAC PDU 235s.

[0146] Figure 3Aspects of a protocol stack 300 supporting enhanced external decoding for broadcast communications, according to one or more aspects of this disclosure, are shown. The aspects of the protocol stack 300 can be implemented as referenced herein. Figure 1 and Figure 2 The described aspects of wireless communication system 100 and wireless communication system 200, or aspects that can be implemented by these aspects. The techniques described in the context of protocol stack 300 can provide enhancements to out-of-application-layer coding.

[0147] According to the techniques described herein, network entities can perform application-layer out-of-layer decoding across application-layer packets 305, where each application-layer packet 305 (and its corresponding MAC PDU 330) may correspond to a single code block (e.g., or several code blocks). Performing out-of-layer decoding at the application layer for the application-layer packet 305 corresponding to a single code block (in size) allows communication from the physical layer to other layers within the protocol stack to be equivalent to code blocks, enabling out-of-layer decoding to occur at the application layer. Therefore, network entities can utilize physical layer code block-level granularity with success or failure indication.

[0148] For example, a network entity may generate multiple application layer packets 305 (e.g., application layer packets 305-a to 305-n). In response to generating multiple application layer packets 305, the network entity may encode the combination of the multiple application layer packets 305 at the application layer using an external code to generate an externally encoded application layer packet 310. In this respect, in addition to one or more parity application layer packets 305 generated by the application layer external code, the externally encoded application layer packet 310 may also include each of the multiple application layer packets 305 (e.g., application layer packets 305-a, application layer packets 305-b, up to application layer packets 305-n).

[0149] As an illustrative example, a network entity may generate 100 application layer packets 305 (e.g., n=100), and then apply an external code across all 100 application layer packets to generate, for example, 5 parity application layer packets 305. Thus, the externally encoded application layer packets 310 may have a total of 105 application layer packets 305, including 100 original application layer packets 305 and 5 parity application layer packets 305.

[0150] In response to generating externally encoded application layer packets 310, the network entity may begin encoding the externally encoded application layer packets 310 at each layer of the protocol stack. For example, the network entity may generate SDAP PDU 315 (e.g., SDAP PDU 315-a, SDAP PDU 315-b, up to SDAP PDU 315-n) for each of the externally encoded application layer packets 310, generate PDCP PDU 320 (e.g., PDCP PDU 320-a, PDCP PDU 320-b, up to PDCP PDU 320-n) based on each of the SDAP PDU 315, and generate RLC PDU 325 (e.g., RLCPDU 325-a, RLC PDU 325-b, up to RLC PDU 325-n) based on each of the PDCP PDU 320. In response to the generation of a PDCP PDU 320 for each externally encoded application layer packet in the externally encoded application layer packet 310, a network entity can generate a MAC PDU 330 at the MAC layer based on the RLC PDU 325 for each externally encoded application layer packet in the externally encoded application layer packet 310.

[0151] As an illustrative example, a network entity can generate MAC PDU 330-a corresponding to application layer packet 305-a, MAC PDU 330-b corresponding to application layer packet 305-b, and MAC PDU 330-n corresponding to application layer packet 305-n. In this way, the network entity can generate a corresponding MAC PDU 330 for each externally encoded application layer packet in the externally encoded application layer packet 310. To avoid increased overhead due to applying a corresponding header to application layer packet 305 at each layer, the network entity can implement header compression techniques, such as robust header compression (ROHC), at one or more layers of the protocol stack. That is, because application layer packet 305 can have a reduced size relative to other application layer packets (e.g., to make the corresponding MAC PDU 330 correspond to a single code block in size), MAC PDU 330 may suffer increased overhead due to each header being applied to application layer packet 305. Therefore, the network entity can implement ROHC.

[0152] In some respects, based on each MAC PDU in the generated MAC PDU 330, the network entity can map each MAC PDU in the MAC PDU 330 to a corresponding TB, where each TB comprises a single code block. For example, at the physical layer, the network entity can map MAC PDU 330-a to a single code block of a first TB, MAC PDU 330-b to a single code block of a second TB, and MAC PDU 330-n to a single code block of the nth TB.

[0153] Based on mapping each MAC PDU in MAC PDU 330 to a corresponding TB, a network entity can map a TB to one or more time slots at the physical layer, wherein the number of TBs mapped to at least a first time slot is greater than one. In a first exemplary aspect, the network entity can map each TB to a first time slot. In another aspect, the network entity can map a first portion of a TB to a first time slot (where the amount of the first portion of the TB is greater than one) and map the remaining portion of the TB to a second time slot. In yet another aspect, the network entity can map multiple portions of a TB to corresponding time slots, such that a first portion of the TB can be mapped to a first time slot, a second portion of the TB can be mapped to a second time slot, a third portion of the TB can be mapped to a third time slot, and so on.

[0154] To broadcast multiple TBs within a single timeslot, network entities can jointly perform rate matching and block concatenation for all TBs mapped to a single timeslot. For example, at the physical layer, network entities can perform rate matching on a per-timeslot basis for each TB within a TB, where rate matching can be based on the total number of blocks used for broadcasting in the corresponding timeslot. Additionally, network entities can concatenate each block within a single timeslot in preparation for transmission, with concatenation performed sequentially.

[0155] As an illustrative example, if a network entity maps a first TB corresponding to application layer packet 305-a and a second TB corresponding to application layer packet 305-b to a first timeslot, the network entity can perform rate matching jointly on the first and second TBs, where rate matching can be based on the number of TBs mapped to the first timeslot (e.g., two). Based on the joint rate matching of the first and second TBs, the network entity can concatenate the first and second TBs sequentially to prepare for broadcast transmission. Therefore, because application layer packet 305-a precedes application layer packet 305-b (e.g., in generation time, in data continuity, etc.), the network entity can append the second TB to the end of the first TB such that the data associated with application layer packet 305-a precedes the data associated with application layer packet 305-b. Joint rate matching and concatenation can be referenced herein. Figure 4 Further description.

[0156] In such cases (e.g., multiple TBs are mapped to a single timeslot), the broadcast network entity may send a corresponding control message (e.g., Downlink Control Information (DCI) for transmission via the Physical Downlink Shared Channel (PDSCH) or Multicast Scheduling Information (MSI) for transmission via the Physical Multicast Channel (PMCH)) to allocate the same timeslot for each of the multiple TBs. As an illustrative example, if the network entity maps a first TB associated with application layer packet 305-a and a second TB associated with application layer packet 305-b to a first timeslot, the network entity may send a first control message to allocate the first timeslot for application layer packet 305-a and a second control message to allocate the first timeslot for application layer packet 305-b. In this way, the network entity can schedule time resources for multiple TBs broadcast via the first timeslot.

[0157] In some other aspects, based on each MAC PDU generated in MAC PDU 330, the network entity can map each MAC PDU to a corresponding code block within one or more transport blocks. For example, the network entity can map MAC PDU 330-a to a first code block of a first TB, MAC PDU 330-b to a second code block of the first TB, and MAC PDU 330-n to an nth code block of the first TB. Alternatively, the network entity can map a first portion of MAC PDU 330 to a corresponding code block of the first TB and the remaining portion of MAC PDU 330 to a corresponding code block of a second TB. In some aspects, the network entity can map a first portion of MAC PDU 330 to a corresponding code block of the first TB, a second portion of MAC PDU 330 to a corresponding code block of the second TB, a third portion of MAC PDU 330 to a corresponding code block of the third TB, and so on.

[0158] In this respect, based on the corresponding code blocks that map the MAC PDU 330 to one or more TBs, a network entity can broadcast one or more TBs via a corresponding time slot. For example, a network entity can send a single TB that includes an equivalent of multiple code blocks (e.g., a MAC PDU) via a single time slot (e.g., on the basis of a single TB per time slot).

[0159] As described herein, each MAC PDU in MAC PDU 330 (e.g., each application layer packet 305 along with a different header) can correspond to a single corresponding code block. That is, the size (in bits) of each MAC PDU in MAC PDU 330 can be equal to or smaller than the predefined size of the code block. In this way, each MAC PDU in MAC PDU 330 can be mapped to a corresponding code block, thereby enabling the receiving network entity to utilize code block-level CRC when performing external decoding at the application layer. In general, although the correspondence between application layer packets 305 and single code blocks (e.g., a correspondence based on single code blocks) is described as a typical example, it should be understood that relatively small application layer packets (in bit size) can be mapped to a relatively reduced number of code blocks in the transport block.

[0160] Network entities can receive broadcast transmissions and decode MAC PDUs. For example, a receiving network entity can receive multiple TBs at the physical layer and decode the TBs to retrieve the code blocks corresponding to MAC PDU 330. The network entity can transmit code blocks (e.g., MAC PDU 330) from the physical layer to the MAC layer, or transmit information associated with code blocks from the physical layer to the MAC layer, allowing the network entity to begin decoding MAC PDU 330 to obtain application layer packet 305. For example, the network entity can indicate from the physical layer to the MAC layer which code blocks were successfully received and decoded (e.g., passed) and which code blocks were not successfully received and decoded (e.g., failed). In some aspects, the network entity can indicate from the physical layer to the MAC layer information associated with groups, blocks, or subsets of code blocks constituting application layer packet 305, such as whether the group of code blocks, each block, or subset of code blocks was successfully decoded.

[0161] The network entity can decode MAC PDU 330 at the MAC layer to obtain RLC PDU 325, and pass RLCPDU 325 to the RLC layer, where it can decode RLC PDU 325 to obtain PDCP PDU 320. The network entity can decode PDCP PDU 320 at the PDCP layer to obtain SDAP PDU 315, and pass SDAP PDU 315 to the SDAP layer. At the SDAP layer, the network entity can decode SDAP PDU 315 to obtain externally encoded application layer packets 310. At the application layer, the network entity can perform external decoding on the externally encoded application layer packets 310 to obtain each original application layer packet in the original application layer packets 305. Based on the external decoding, the network entity can verify at the code block level which application layer packets 305 are fully decoded by the protocol stack or fail to be decoded. That is, because each application layer packet 305 is associated with a corresponding code block, the receiving network entity can identify which code blocks (e.g., application layer packet 305) have failed based on the generated parity application layer packet 305, thereby utilizing block-level CRC when performing application layer out-of-layer decoding.

[0162] Figure 4 A process flow 400 supporting enhanced external decoding for broadcast communications, according to one or more aspects of this disclosure, is illustrated. Process flow 400 can be implemented as referenced herein. Figures 1 to 3 The aspects of the described wireless communication system 100, wireless communication system 200, and protocol stack 300, or those implemented by these aspects. The techniques described in the context of process flow 400 enable network entities to map multiple TBs 405 to a single timeslot for broadcast transmission.

[0163] As described herein, in some aspects, a network entity may map multiple MAC PDUs (e.g., such as MAC PDU 330) to a single code block of a corresponding TB 405, such that each TB 405 corresponds to a single MAC PDU. In such aspects, to avoid reducing the throughput of broadcast transmissions, the network entity may map multiple TB 405s to a single time slot (e.g., similar to MIMO or URLLC transmissions). To broadcast multiple TBs via a single time slot, the network entity may jointly perform a rate matching process and a code block concatenation process for all TB 405s in a single time slot, resulting in resource element mapping. Essentially, the network entity creates concatenated TB 405s, where, during mapping to resource elements, in the concatenated TB 405s, a code block of TB 405-a is immediately followed by a code block of TB 405-b. That is, the network entity may sequentially combine single code blocks from each TB 405 into a single concatenated TB 405, thereby enabling the network entity to map the concatenated TB 405s to time slots.

[0164] For example, network entities can refer to this article. Figure 3 The described technique maps a first MAC PDU to TB 405-a, a second MAC PDU to TB 405-b, and an nth MAC PDU to a single code block of TB 405-n at the physical layer. In response to mapping the MAC PDU to TB 405, a network entity can begin resource element-to-TB mapping to map TB 405 (e.g., TB 405-a to TB 405-n) to a first time slot.

[0165] For example, at 410, the network entity can perform the TB CRC attach procedure individually for all TB 405. As an illustrative example, at 410-a, the network entity can perform the TB CRC attach procedure for TB 405-a, while at 410-b, the network entity can perform the TB CRC attach procedure individually for TB 405-b. Similarly, at 410-n, the network entity can perform the TB CRC attach procedure for TB405-n.

[0166] At 415, the network entity can perform block segmentation and CRC attachment procedures individually for all TB 405. As an illustrative example, at 415-a, the network entity can perform block segmentation and CRC attachment procedures for the block associated with TB 405-a, while at 415-b, the network entity can perform block segmentation and CRC attachment procedures for the block associated with TB 405-b. Similarly, at 415-n, the network entity can perform the TB CRC attachment procedure for TB 405-n.

[0167] At 420, the network entity can perform a channel decoding procedure individually for all TB 405. As an illustrative example, at 420-a, the network entity can perform a channel decoding procedure for the code block associated with TB 405-a, while at 420-b, the network entity can perform a channel decoding procedure for the code block associated with TB 405-b. Similarly, at 420-n, the network entity can perform a TB CRC attachment procedure for TB 405-n.

[0168] At 425, network entities can jointly perform rate matching for each TB in TB 405, where rate matching is based on the total number of code blocks to be broadcast in the first timeslot mapped to TB 405. For example, network entities can perform rate matching where the input to the formula for performing rate matching across TB 405 can be the total number of code blocks to be mapped onto all TBs 405 in the first timeslot. That is, network entities can consider the total number of code blocks to be transmitted via the first timeslot when performing rate matching for each TB 405.

[0169] As an illustrative example, if a network entity maps 100 MAC PDUs to corresponding code blocks in 100 TBs (e.g., 100 code blocks), the network entity can use the input of 100 code blocks to perform rate matching for each TB 405. In this way, the network entity can perform rate matching for each TB 405 based on the total number of code blocks mapped to time slots.

[0170] At 430, the network entity can serially concatenate code blocks from each TB 405 to generate a sequential set of code blocks corresponding to all TB 405s mapped to the first time slot. For example, the network entity can concatenate each code block within the first time slot to prepare for broadcasting of TB 405s, where the network entity can perform concatenation in the order of the TB 405s. As an illustrative example, if TB 405-a precedes TB 405-b, the network entity can append the code block of TB 405-b to the end of the code block of TB 405-a, such that the data associated with TB 405-a precedes the data associated with TB 405-b. In this way, the network entity can generate concatenated TB 405s comprising multiple code blocks from different TB 405s for broadcast transmission in a single time slot.

[0171] Figure 5 Aspects of a protocol stack 500 supporting enhanced external decoding for broadcast communications, according to one or more aspects of this disclosure, are illustrated. The aspects of the protocol stack 500 can be implemented as referenced herein. Figures 1 to 4The described aspects of wireless communication system 100, wireless communication system 200, protocol stack 300, and process flow 400, or aspects that can be implemented by these aspects. The techniques described in the context of protocol stack 500 enable network entities (e.g., such as network entity 105-a) to perform physical or MAC layer out-of-layer coding for broadcast transmission.

[0172] For example, a network entity (e.g., a broadcast network entity) may generate multiple application layer packets 505 (e.g., application layer packets 505-a to 505-n) for broadcasting. Based on the generation of multiple application layer packets 505, the network entity may use a protocol stack to encode the application layer packets 505. For example, the network entity may generate SDAP PDU 510 (e.g., SDAP PDU 510-a to SDAP PDU 510-n) for each application layer packet 505 at the SDAP layer. The network entity may generate PDCP PDU 515 (e.g., PDCP PDU 515-a to PDCP PDU 515-n) for each SDAP PDU 510 at the PDCP layer, and generate RLCPDU 520 (e.g., RLC PDU 520-a to RLC PDU 520-n) for each PDCP PDU 515 at the RLC layer.

[0173] At the MAC layer, the network entity can generate multiple MAC PDUs 525 for each RLC PDU in RLC PDU 520. That is, the network entity can generate a MAC PDU 525 for each application layer packet 505. As an illustrative example, the network entity can generate a MAC PDU 525-a corresponding to or otherwise including the data of application layer packet 505-a. Similarly, the network entity can generate a MAC PDU 525-n corresponding to or otherwise including the data of application layer packet 505-n.

[0174] To increase reliability and enable QEF transmission for broadcasting, network entities may apply external codes to multiple MAC PDUs 525 at an external encoder layer between the physical and MAC layers, at the physical layer, or at the MAC layer to generate externally encoded MAC PDUs 530. For example, network entities may combine (e.g., concatenate) each MAC PDU 525 (e.g., MAC PDU 525-a up to MAC PDU 525-n) to generate concatenated MAC PDUs 525.

[0175] In this respect, the number of bits in a concatenated MAC PDU 525 can be based on the number of TB535s allocated for broadcast transmission, the number of code blocks per TB535, and the number of parity bits associated with external decoding. That is, to perform concatenation, a network entity can identify its size (in bits) as equal to (T × C) - C. parity The number of bits per MAC PDU 525 (e.g., application layer packets 505-a to 505-n), where T represents the number of TB 535s allocated for broadcast transmission, C represents the number of code blocks in TB 535 (e.g., in bits), and C parity This indicates the number (e.g., in bits) of parity code blocks that can be appended to the cascaded MACPDU 525 to generate the externally encoded MAC PDU 530.

[0176] Network entities can concatenate the identified number of MAC PDU 525s to generate concatenated MAC PDU 525s. Network entities can then encode the concatenated MAC PDU 525s using an external code to generate multiple parity check code blocks (e.g., C...). parity That is, network entities can use erasure codes (e.g., external codes) (such as Raptor codes, RaptorQ codes, modified XOR codes, or combinations thereof) to generate multiple parity bits. Network entities can append concatenated MAC PDU 525 with multiple parity code blocks (e.g., bits) to generate an externally encoded MAC PDU 530.

[0177] In response to generating an externally encoded MAC PDU 530, the network entity may segment the externally encoded MAC PDU 530 into the number of TBs 535 (e.g., T TBs) allocated for broadcast transmission over the physical layer. As an illustrative example, the network entity may segment the externally encoded MAC PDU 530 into t segments, where each of the t segments can be mapped to a corresponding TB 535 and includes data associated with one or more MAC PDUs 525.

[0178] Based on the segmentation of the externally encoded MAC PDU 530, a network entity can map each segment of the externally encoded MAC PDU 530 to a corresponding TB 535, map each corresponding TB 535 to frequency resources (e.g., a single-frequency network (SFN)) and time slots (e.g., subframes), encode each TB 535 using internal codes (e.g., using LDPC or Turbo codes to perform channel decoding), and broadcast multiple TB 535s. Continuing with the foregoing illustrative example, a network entity can map the first segment of the externally encoded MAC PDU 530 to TB 535-a, the second segment of the externally encoded MAC PDU 530 to TB 535-b, and the t-th segment of the externally encoded MAC PDU 530 to TB 535-t, and broadcast each TB of the t TB535s via the corresponding time and frequency resources. In this way, the network entity can perform physical layer or MAC layer external encoding, thereby improving the reliability of broadcast communications.

[0179] Such external encoding operations can be performed by the external encoding layer of a network entity that operates between the MAC layer and the physical layer. Additionally or alternatively, the MAC layer of a network entity, the physical layer of a network entity, or a combination thereof can perform all or part of the aforementioned external encoding operations.

[0180] In this way, the outer coding layer (e.g., the layer that performs outer decoding) can have access to the physical layer's block-level CRC, enabling the decoder of the broadcast transmission to decode the broadcast transmission using the block-level CRC. For example, during decoding, the receiving network entity can decode the outer-coded MAC PDU 530 at the outer coding layer to obtain each MAC PDU in MAC PDU 525, thereby utilizing the block CRC, and generate a decoding message based on whether the block associated with the outer-coded MAC PDU 530 has been successfully decoded (e.g., whether N MAC PDUs have been successfully decoded). For example, if each block associated with the outer-coded MAC PDU is successfully decoded, the network entity can generate a success message (e.g., all successful). Alternatively, if the block associated with the outer-coded MAC PDU 530 is not successfully decoded, the network entity can generate a failure message (e.g., all failed). Based on the decoding of the outer-coded MAC PDU 530, the outer coding layer can send MAC PDU 525 and the decoding message (e.g., success or failure message) to the MAC layer. The MAC layer can then begin the process of decoding each MAC PDU in MAC PDU 525 to pass it up the protocol stack.

[0181] In this way, because the parity bit is generated based on the block-level MAC PDU 525, the receiving network entity can use the block-level parity bit to identify which blocks (if any) were not successfully transmitted. Therefore, at the outer coding layer, the receiving network entity can pass success or failure messages to the MAC layer, so that the MAC layer can have an indication of which blocks (e.g., MAC PDU 525) were not successfully decoded or were successfully decoded.

[0182] To perform the decoding operation, the broadcast network entity may broadcast control signaling indicating the external encoding information associated with the broadcast external encoding. For example, the broadcast network entity may broadcast a corresponding index associated with each TB in TB 535 (e.g., to identify the order in which TB 535 is to be decoded), an indication of the external code used to generate the external encoding in the MAC PDU 530, an indication of the decoding rate of the MAC PDU 530 used to generate the external encoding, or a combination thereof, as part of the external encoding information. Therefore, the receiving network entity can use the external encoding information to decode the externally encoded MAC PDU 530.

[0183] Broadcast network entities can broadcast externally encoded information via scheduling or control signaling from the MAC layer, such as via MSI signaling. In some respects, broadcast network entities can broadcast MSIs formatted for physical or MAC layer external decoding. Because the operational cost of losing such a signal is relatively high, broadcast network entities can transmit MSIs with relatively high reliability compared to the current MSI transmission used for broadcasting. For example, if a receiving network entity fails to receive the MSI associated with a broadcast transmission of TB 535, the entire set of n application layer packets 505 may be lost. To mitigate such failures, the broadcast network entity can repeatedly broadcast the MSI to the receiving network entity.

[0184] As an illustrative example, a broadcasting network entity may broadcast the original MSI and multiple repetitions of the MSI to ensure that a receiving network entity successfully receives the MSI. Additionally or alternatively, to mitigate lost MSIs, a network entity may broadcast the MSI using a lower modulation and decoding scheme (MCS) relative to the MSC used for the current MSI broadcast. MSI indications can be referenced herein. Figure 6 Further description.

[0185] Figure 6 A resource diagram 600 is shown, according to one or more aspects of this disclosure, supporting enhanced external decoding for broadcast communications. The aspects of resource diagram 600 can be implemented as referenced herein. Figures 1 to 5The described aspects of wireless communication system 100, wireless communication system 200, protocol stack 300, process flow 400, and protocol stack 500, or aspects thereof, may be implemented by these aspects. For example, resource diagram 600 may be an example of broadcast transmission including TB set 605-a and TB set 605-b, wherein TB set 605-a may include data associated with a first externally encoded MAC PDU, and TB set 605-b includes data associated with a second externally encoded MAC PDU.

[0186] Resource diagram 600 may include one or more SFNs (e.g., SFN 0 to SFN 26), wherein a single SFN may span a frequency bandwidth and be used for broadcast communications. Each SFN may be segmented into multiple subframes (SF) (e.g., SF#0 to SF#13), wherein a subframe may include multiple time slots that may be used for broadcast multicast channels (MTCH) (e.g., data channels) or multicast control channels (MCCH).

[0187] Additionally, resource graph 600 can be segmented into various Multimedia Broadcast Multicast Service Single Frequency Networks (MBSFNs) 610, where each MBSFN 610 can span multiple SFs. As an illustrative example, SFs 1 to SF 4 and SFs 9 to SF 11 can be assigned to MBSFN 610-a, while SFs 5 to SF 8 and SFs 12 to SF 13 can be assigned to MBSFN 610-b.

[0188] As described herein, a broadcast network entity may perform physical layer or MAC layer external encoding to utilize block-level CRC in broadcast transmissions. For example, a broadcast network entity may use external codes to encode multiple MAC PDUs (e.g., MAC PDU 525) to generate a first externally encoded MAC PDU (e.g., externally encoded MAC PDU 530), and also use external codes to encode multiple second MAC PDUs to generate a second externally encoded MAC PDU. The broadcast network entity may refer to the references herein. Figure 5 The described technique maps a first externally encoded MAC PDU to a TB set 605-a and a second externally encoded MAC PDU to a TB set 605-b.

[0189] Based on mapping externally encoded MAC PDUs to corresponding TB sets 605, a broadcast network entity can map TB set 605 to MBSFN 610 and the corresponding MTCHs of each SF and SFN spanning MBSFN 610. As an illustrative example, a broadcast network entity can map TB set 605-a associated with a first externally encoded MAC PDU to SF #2, SF #3, SF #4, SF #9, SF #10, and SF #11 of a first SFN and SF #1, SF #2, SF #3, and SF #4 of a second SFN. Similarly, the broadcast network can map TB set 605-b associated with a second externally encoded MAC PDU to SF #9, SF #10, and SF #11 of a second SFN and SF #1, SF #2, SF #3, SF #4, SF #9, SF #10, and SF #11 of a third SFN. The network entity can broadcast TB set 605 via the corresponding MTCH based on the mapping.

[0190] According to the techniques described herein, in order for a receiver of a broadcast transmission to decode TB set 605, a broadcast network entity may broadcast an MSI (potentially with repetition) for MBSFN 610-a and for a given MBMS service to indicate the external decoding architecture across the scheduled MTCH (data TB set 605). For example, the broadcast network entity may broadcast an MSI indicating external encoding information, such as a corresponding index associated with each TB set in TB set 605, an indication of the external code used to generate the MAC PDU for external encoding, an indication of the decoding rate used to generate the MAC PDU for external encoding, or a combination thereof.

[0191] As an illustrative example, a broadcast network entity may broadcast an MSI via SF#1 of a first SFN, wherein the broadcast network entity may indicate that MTCHs (e.g., TB set 605-a) broadcast via SF#2, SF#3, SF#4, SF#9, SF#10, and SF#11 of the first SFN and SF#1, SF#2, SF#3, and SF#4 of the second SFN are associated with a first externally encoded MAC PDU, while MTCHs (e.g., TB set 605-a) broadcast via SF#9, SF#10, and SF#11 of the second SFN and SF#1, SF#2, SF#3, SF#4, SF#9, SF#10, and SF#11 of the third SFN are associated with a second externally encoded MAC PDU. In this way, the broadcast network entity can indicate via the MSI which TBs are associated with the same externally encoded MAC PDU, thereby enabling the receiving network entity to receive, identify, and decode each externally encoded MAC PDU.

[0192] Figure 7A process flow 700 supporting enhanced external decoding for broadcast communications, according to one or more aspects of this disclosure, is illustrated. Aspects of process flow 700 can be implemented as referenced herein. Figures 1 to 6 The described aspects of wireless communication system 100, wireless communication system 200, protocol stack 300, process flow 400, protocol stack 500, and resource graph 600, or aspects thereof, may be implemented by these aspects. Process flow 700 may include network entity 105-c, which may be an example of a broadcast network entity or network entity 105-a. Process flow 700 may also include network entity 105-d, which may be an example of a receiving network entity or network entity 105-b. The techniques described in the context of process flow 700 enable network entity 105-c to enhance application layer out-of-layer decoding, for example, as referenced herein. Figure 3 and Figure 4 As described.

[0193] At position 705, network entity 105-c can be referenced in this document. Figure 3 The described technique encodes multiple application layer packets (e.g., application layer packet 305) at the application layer using application-level external codes to generate externally encoded application layer packets (e.g., externally encoded application layer packet 310).

[0194] At 710, network entity 105-c can generate multiple MAC PDUs at the MAC layer, where each MAC PDU can be associated with a corresponding externally encoded application layer packet. For example, network entity 105-c can encode each application layer packet via the various layers of the protocol stack to generate multiple MAC PDUs.

[0195] At point 715, in one aspect, network entity 105-c can be referenced in this document. Figure 3 The described technique maps each of a plurality of MAC PDUs to a corresponding TB at the physical layer. Alternatively, network entity 105-c can map each MAC PDU to one or more code blocks of a single TB, as referenced herein. Figure 3 As described. In either case, each MAC PDU may correspond in size to a corresponding single code block. That is, each MAC PDU may include a number of bits equal to the predefined bit size of the code block.

[0196] At 720, if network entity 105-c can map each MAC PDU to a single code block of a single TB (e.g., a TB comprises a single code block), then network entity 105-c can perform rate matching across TBs mapped to the one or more time slots on a per-slot basis, where the rate matching across TBs is based on the total number of code blocks mapped to that time slot. Additionally, at 725, network entity 105-c can concatenate each code block within a time slot of one or more time slots based on the order of the TBs mapped to the single time slot to prepare for the broadcast of multiple transport blocks. This rate matching and concatenation can be described as referenced herein. Figure 4 As described in 425 and 430, this is to be performed.

[0197] In some respects, at 730, network entity 105-c may broadcast a scheduling permission for a time slot (time resource) used for broadcast transmission. For example, if network entity 105-a maps multiple MAC PDUs to a single TB, the network entity may indicate via scheduling permission that a first time slot is used for the multiple TBs. Alternatively, if network entity 105-a maps each MAC PDU to a corresponding time slot, the network entity may indicate via scheduling permission the allocation of multiple time slots for broadcast transmission, wherein a single time slot among the multiple time slots is used for the broadcast of a single TB. As described herein, the network entity may broadcast the scheduling permission via control signaling, wherein the control signaling is one of a DCI or MSI message. At 735, network entity 105-c may broadcast multiple TBs.

[0198] At 740, network entity 105-d can obtain application layer packets. In some aspects, based on the received TB, network entity 105-d can obtain multiple MAC PDUs from the TB. In one aspect, to obtain the MAC PDUs, network entity 105-d can communicate each transport block in the multiple TBs from the physical layer to the MAC layer. In another aspect, network entity 105-d can communicate information about at least one code block of the TB from the physical layer to the MAC layer. Network entity 105-d can then obtain externally encoded application layer packets at its application layer. Based on the obtained externally encoded application layer packets, network entity 105-d can perform external decoding to obtain each original application layer packet in the original application layer packets.

[0199] Figure 8 A process flow 800 supporting enhanced external decoding for broadcast communications, according to one or more aspects of this disclosure, is illustrated. Aspects of process flow 800 can be implemented as referenced herein. Figures 1 to 7The described aspects of wireless communication system 100, wireless communication system 200, protocol stack 300, process flow 400, protocol stack 500, resource graph 600, and process flow 700, or aspects that can be implemented by these aspects, are described. Process flow 800 may include network entity 105-e, which may be an example of a broadcast network entity or network entity 105-a. Process flow 800 may also include network entity 105-f, which may be an example of a receiving network entity or network entity 105-b. The techniques described in the context of process flow 800 enable network entity 105-e to perform physical or MAC layer out-of-layer decoding, for example, as referenced herein. Figure 5 and Figure 6 As described.

[0200] At 805, network entity 105-e may generate multiple MAC PDUs (e.g., MACPDU 525) based on the corresponding application layer packets. For example, network entity 105-e may generate application layer packets (e.g., application layer packet 505), encode each application layer packet at each layer of the protocol stack, and generate MAC PDUs.

[0201] At 810, network entity 105-e may encode multiple MAC PDUs using an external code (e.g., Raptor code, RaptorQ code, or modified XOR code) to generate an externally encoded MAC PDU (e.g., externally encoded MAC PDU 530). To encode multiple MAC PDUs, network entity 105-e may first concatenate the multiple MAC PDUs to generate a concatenated MAC PDU. In this respect, the number of bits in the concatenated MAC PDU may be equal to the number of TBs allocated for broadcast transmission, the number of code blocks per TB, the number of parity bits, or a combination thereof. Based on generating the concatenated MAC PDU, network entity 105-e may encode the concatenated MAC PDU using an external code to generate multiple parity bits (e.g., multiple parity code blocks), and append the concatenated MAC PDU with the multiple parity bits to generate an externally encoded MAC PDU.

[0202] At 815, network entity 105-e can segment an out-to-out-coded MAC PDU into multiple TBs. For example, network entity 105-e can segment an out-to-out-coded MAC PDU into a number of segments equal to the number of TBs allocated for broadcast transmission. In response to segmenting the out-to-out-coded MAC PDU, network entity 105-e can perform intra-channel decoding on each TB using turbo or LDPC codes. Network entity 105-e can map each coded TB in the encoded TB to the corresponding time and frequency resources.

[0203] At 820, network entity 105-e may broadcast control signaling (such as multicast scheduling information) indicating which TBs include the corresponding segments of the externally encoded MAC PDU. For example, network entity 105-e may broadcast multicast scheduling information indicating one or more SFs and SFNs of the segment carrying the externally encoded MAC PDU, as referenced herein. Figure 6 As described.

[0204] In some respects, network entity 105-e may indicate via multicast scheduling information an index associated with each TB, an indication of the external code used to generate the external code MAC PDU (e.g., whether Raptor, RaptorQ, modified XOR or other codes are used), an indication of the decoding rate of the external code, or a combination thereof, such that network entity 105-f may use such indications to decode each TB, obtain the external code MAC PDU, and decode the external code MAC PDU.

[0205] In some respects, to increase the reliability of broadcasting multicast scheduling information, network entity 105-e may repeatedly broadcast the MSI, such that network entity 105-f can receive the initial MSI as well as one or more repetitions of the MSI. Additionally or alternatively, network entity 105-e may use an MCS smaller than the second MCS used for the second MSI to broadcast the MSI.

[0206] At 825, network entity 105-e may broadcast the multiple TBs, each TB being broadcast via a corresponding timeslot. In some aspects, network entity 105-f may receive each TB via a corresponding timeslot, obtain each segment of the externally encoded MAC PDU from each TB after performing internal decoding, and perform external decoding on the MAC PDU based on information received via MSI. Network entity 105-f may generate a decoding message based on whether network entity 105-f has successfully decoded each segment of the externally encoded MAC PDU (e.g., each of the multiple MAC PDUs). For example, network entity 105-f may generate a success message indicating that each segment of the externally encoded MAC PDU has been successfully decoded and obtained, and indicate the success message from the physical or external decoding layer to the MAC layer.

Any function or operation described herein that can be performed by a processor may be performed by multiple processors capable of performing the described functions or operations individually or jointly.

[0441] The functions described herein can be implemented using hardware, software executed by a processor, firmware, or any combination thereof. When implemented using software executed by a processor, the functions can be stored as one or more instructions or code on a computer-readable medium or transmitted using one or more instructions or code on a computer-readable medium. Other aspects and specific implementations are within the scope of this disclosure and the claims. For example, due to the nature of software, the functions described herein can be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination of these. Features implementing the functions can also be physically located in various locations, including various portions distributed such that the functions are implemented in different physical locations.

[0442] Computer-readable media includes both non-transitory computer storage media and communication media, encompassing any medium that facilitates the transfer of a computer program from one location to another. Non-transitory storage media can be any available medium accessible by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compressed optical disc (CD) ROM or other optical disc storage devices, magnetic disk storage devices or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store desired program code components in the form of instructions or data structures, and accessible by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Furthermore, any connection is appropriately referred to as computer-readable media.

[0443] As used herein, the term "or" is inclusive unless restrictive language is used relative to the listed alternatives. For example, a reference to "X is based on A or B" should be interpreted as including, within its scope, X is based on A, X is based on B, and X is based on both A and B. In this respect, a reference to "X is based on A or B" means "at least one of A or B" or "one or more of A or B," because "or" is inclusive. Similarly, a reference to "X is based on A, B, or C" should be interpreted as including, within its scope, X is based on A, X is based on B, X is based on C, X is based on both A and B, X is based on both A and C, X is based on both B and C, and X is based on both A, B, and C. In this respect, a reference to "X is based on A, B, or C" means "at least one of A, B, or C" or "one or more of A, B, or C," because "or" is inclusive. As an example of restrictive language, the reference to "X is based on either A or B" should be interpreted as including, within its scope, both X based on A and X based on B, but excluding X based on both A and B. Furthermore, as used herein, the phrase "based on" should not be interpreted as a reference to a closed set of information, one or more conditions, one or more factors, etc. In other words, the phrase "based on A" (where "A" can be information, conditions, factors, etc.) should be interpreted as "based on at least A," unless specifically stated differently. Moreover, as used herein, the phrase "set" should be understood to include the possibility of a set having one member. That is, the phrase "set" should be interpreted in the same way as "one or more" or "at least one."

[0444] As used herein, including in claims, the article “a” preceding a noun is open-ended and is understood to refer to “at least one” or “one or more” of those nouns. Therefore, the terms “a,” “at least one,” “one or more,” and “at least one of one or more” are interchangeable. For example, where a claim enumerates “components” performing one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “component” having a characteristic or performing a function may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent references to a component introduced with the article “a” using the terms “the” or “the” can refer to any or all of the one or more components. For example, a component introduced with the article “a” can be understood to mean “one or more components,” and subsequent reference to “the component” in a claim can be understood as equivalent to referring to “at least one of the one or more components.” Similarly, subsequent references to a component introduced with the terms “the” or “the” as “one or more components” can refer to any or all of the one or more components. For example, reference to "the one or more components" in the subsequent claims can be understood as equivalent to reference to "at least one of the one or more components".

[0445] The term "determine" encompasses a variety of actions, and therefore, "determine" can include calculation, computation, processing, derivation, investigation, lookup (such as by searching in a table, database, or other data structure), identification, and similar actions. Furthermore, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory), etc. Moreover, "determine" can include parsing, obtaining, selecting, choosing, building, and other similar actions.

[0446] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type can be distinguished by adding a dash after the reference numeral and a second reference numeral to differentiate them. If only the first reference numeral is used in the description, the description can be applied to any of the similar components having the same first reference numeral, regardless of the second or other subsequent reference numerals.

[0447] This document describes example configurations in conjunction with the accompanying drawings and does not represent all aspects that can be implemented or are within the scope of the claims. The terms "aspect" or "example" as used herein mean "serving as an aspect, example, instance, or illustration," and not "preferred" or "advantageous over other examples." The detailed description includes specific details used to provide an understanding of the described techniques. However, these techniques can be practiced without these specific details. In some instances, structures and devices are shown in block diagram form to avoid obscuring the concepts of the described aspects.

[0448] The description herein is provided to enable those skilled in the art to implement or use this disclosure. Various modifications to this disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the aspects and designs described herein, but should be granted the widest scope consistent with the principles and novel features disclosed herein.
