Each network communication devices, such as a base station may support wireless communications for one or multiple user communication devices, which may be otherwise known as UE, or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices by utilizing resources of the wireless communication system (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) . Additionally, the wireless communications system may support wireless communications across various radio access technologies including third generation (3G) radio access technology, fourth generation (4G) radio access technology, fifth generation (5G) radio access technology, among other suitable radio access technologies beyond 5G (e.g., sixth generation (6G) ) .
[0003] Data to be communicated, for example, semantic information may have a basic unit, e.g. a sentence, an image which to be inputted to the neutral network and processed together. If only part of bits of the basic unit can be recovered, it is useless for information recovery at a receiver side.

[0070] Aspects of the present disclosure are described in the context of a wireless communications system.
[0071] Fig. 1 illustrates an example of a wireless communications system 100 for data channel communication in accordance with aspects of the present disclosure. The wireless communications system 100 may include one at least one of network entities 102 (also referred to as network equipment (NE) ) , one or more terminal devices or UEs 104, a core network 106, and a packet data network 108. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE network or an LTE-advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a 5G network, such as an NR network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including institute of electrical and electronics engineers (IEEE) 802.11 (Wi-Fi) , IEEE 802.16 (WiMAX) , IEEE 802.20. The wireless communications system 100 may support radio access technologies beyond 5G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA) , frequency division multiple access (FDMA) , or code division multiple access (CDMA) , etc.
[0072] The network entities 102 may be collectively referred to as network entities 102 or individually referred to as a network entity 102.
[0073] The network entities 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the network entities 102 described herein may be or include or may be referred to as a network node, a base station (BS) , a network element, a radio access network (RAN) node, a base transceiver station, an access point, a NodeB, an eNodeB (eNB) , a next-generation NodeB (gNB) , or other suitable terminology. A network entity 102 and a UE 104 may communicate via a communication link 110, which may be a wireless or wired connection. For example, a network entity 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface. The network entities 102 may be collectively referred to as network entities 102 or individually referred to as a network entity 102. Hereinafter, some implementations of the present disclosure will be described by taking a base station as an example of the network entity 102. Thus, the network entity 102 may be used interchangeably with the base station 102.
[0074] A network entity 102 may provide a geographic coverage area 112 for which the network entity 102 may support services (e.g., voice, video, packet data, messaging, broadcast, etc. ) for one or more UEs 104 within the geographic coverage area 112. For example, a network entity 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc. ) according to one or multiple radio access technologies. In some implementations, a network entity 102 may be moveable, for example, a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas 112 associated with the same or different radio access technologies may overlap, but the different geographic coverage areas 112 may be associated with different network entities 102. Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.
[0075] The one or more UEs 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a mobile device, a wireless device, a remote device, a remote unit, a handheld device, or a subscriber device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an internet-of-things (IoT) device, an internet-of-everything (IoE) device, or machine-type communication (MTC) device, among other examples. In some implementations, a UE 104 may be stationary in the wireless communications system 100. In some other implementations, a UE 104 may be mobile in the wireless communications system 100.
[0076] The one or more UEs 104 may be devices in different forms or having different capabilities. Some examples of UEs 104 are illustrated in Fig. 1. A UE 104 may be capable of communicating with various types of devices, such as the network entities 102, other UEs 104, or network equipment (e.g., the core network 106, the packet data network 108, a relay device, an integrated access and backhaul (IAB) node, or another network equipment) , as shown in Fig. 1. Additionally, or alternatively, a UE 104 may support communication with other network entities 102 or UEs 104, which may act as relays in the wireless communications system 100.
[0077] A UE 104 may also be able to support wireless communication directly with other UEs 104 over a communication link 114. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link 114 may be referred to as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface. A UE 104 may be an A-IoT device.
[0078] A network entity 102 may support communications with the core network 106, or with another network entity 102, or both. For example, a network entity 102 may interface with the core network 106 through one or more backhaul links 116 (e.g., via an S1, N2, N3, or another network interface) . The network entities 102 may communicate with each other over the backhaul links 116 (e.g., via an X2, Xn, or another network interface) . In some implementations, the network entities 102 may communicate with each other directly (e.g., between the network entities 102) . In some other implementations, the network entities 102 may communicate with each other or indirectly (e.g., via the core network 106) . In some implementations, one or more network entities 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC) . An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as a radio heads, smart radio heads, or transmission-reception points (TRPs) . A network entity 102 may be a reader for an A-IoT device.
[0079] In some implementations, a network entity 102 may be configured in a disaggregated architecture, which may be configured to utilize a protocol stack physically or logically distributed among two or more network entities 102, such as an integrated access backhaul (IAB) network, an open radio access network (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, a network entity 102 may include one or more of a central unit (CU) , a distributed unit (DU) , a radio unit (RU) , a RAN intelligent controller (RIC) (e.g., a near-real time RIC (Near-RT RIC) , a non-real time RIC (Non-RT RIC) ) , a service management and orchestration (SMO) system, or any combination thereof.
[0080] An RU may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 102 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 102 may be located in distributed locations (e.g., separate physical locations) . In some implementations, one or more network entities 102 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0081] Split of functionality between a CU, a DU, and an RU may be flexible and may support different functionalities depending upon which functions (e.g., network layer functions, protocol layer functions, baseband functions, radio frequency functions, and any combinations thereof) are performed at a CU, a DU, or an RU. For example, a functional split of a protocol stack may be employed between a CU and a DU such that the CU may support one or more layers of the protocol stack and the DU may support one or more different layers of the protocol stack. In some implementations, the CU may host upper protocol layer (e.g., a layer 3 (L3) , a layer 2 (L2) ) functionality and signaling (e.g., radio resource control (RRC) , service data adaption protocol (SDAP) , packet data convergence protocol (PDCP) ) . The CU may be connected to one or more DUs or RUs, and the one or more DUs or RUs may host lower protocol layers, such as a layer 1 (L1) (e.g., physical (PHY) layer) or an L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160.
[0082] Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU and an RU such that the DU may support one or more layers of the protocol stack and the RU may support one or more different layers of the protocol stack. The DU may support one or multiple different cells (e.g., via one or more RUs) . In some implementations, a functional split between a CU and a DU, or between a DU and an RU may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU, a DU, or an RU, while other functions of the protocol layer are performed by a different one of the CU, the DU, or the RU) .
[0083] A CU may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU may be connected to one or more DUs via a midhaul communication link (e.g., F1, F1-c, F1-u) , and a DU may be connected to one or more RUs via a fronthaul communication link (e.g., open fronthaul (FH) interface) . In some implementations, a midhaul communication link or a fronthaul communication link may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 102 that are in communication via such communication links.
[0084] The core network 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The core network 106 may be an evolved packet core (EPC) , or a 5G core (5GC) , which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management functions (AMF) ) and a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a packet data network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc. ) for the one or more UEs 104 served by the one or more network entities 102 associated with the core network 106.
[0085] The core network 106 may communicate with the packet data network 108 over one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The packet data network 108 may include an application server 118. In some implementations, one or more UEs 104 may communicate with the application server 118. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the core network 106 via a network entity 102. The core network 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server 118 using the established session (e.g., the established PDU session) . The PDU session may be an example of a logical connection between the UE 104 and the core network 106 (e.g., one or more network functions of the core network 106) .
[0086] In the wireless communications system 100, the network entities 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) ) to perform various operations (e.g., wireless communications) . In some implementations, the network entities 102 and the UEs 104 may support different resource structures. For example, the network entities 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the network entities 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the network entities 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures) . The network entities 102 and the UEs 104 may support various frame structures based on one or more numerologies.
[0087] One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.
[0088] A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames) . Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.
[0089] Additionally or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., μ=0, μ=1, μ=2, μ=3, μ=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot may include a number (e.g., quantity) of symbols (e.g., OFDM symbols) . In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing) , a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., μ=0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.
[0090] In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (510 MHz –7.125 GHz) , FR2 (24.25 GHz –52.6 GHz) , FR3 (7.125 GHz –24.25 GHz) , FR4 (52.6 GHz –114.25 GHz) , FR4a or FR4-1 (52.6 GHz –71 GHz) , and FR5 (114.25 GHz –300 GHz) . In some implementations, the network entities 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the network entities 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data) . In some implementations, FR2 may be used by the network entities 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.
[0091] FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies) . For example, FR1 may be associated with a first numerology (e.g., μ=0) , which includes 15 kHz subcarrier spacing; a second numerology (e.g., μ=1) , which includes 30 kHz subcarrier spacing; and a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies) . For example, FR2 may be associated with a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., μ=3) , which includes 120 kHz subcarrier spacing.
[0092] For retransmission of semantic information, the semantic information may be treated as information of a higher layer or information blocks in physical layer. From the physical layer perspective, it only sees some bits without knowing the meaning or relationship of or among each bit. The bits may be transmitted via HARQ in the physical layer. Retransmission in the physical layer may be triggered to correct some bits which are not correctly transmission previously. When reaching max retransmission times and it cannot be recovered, then a high layer ARQ will be triggered for retransmission of a whole packet. Semantic packets may be multiplexed with other information packets (e.g. the packet is not related to semantic information) as shown in Fig. 2. Even for different semantic packets, a transmission boundary may not be aligned with a packet boundary. The reason is that he transmission boundary may only consider unit size of each packet for a transmission.
[0093] Fig. 3 illustrates a signaling chart illustrating an example process 300 for data channel communication in accordance with aspects of the present disclosure. The process 300 may involve the UE 104 and the base station 102. For the purpose of discussion, the process 300 will be described with reference to Fig. 1. With the process 300, efficiency and accuracy of the data channel communication may be improved, especially for semantic information communication.
[0094] As shown in Fig. 3, the base station 102 may transmit 310, to the UE 104, a signaling indicating a communication of an uplink or downlink data channel. Accordingly, the UE 104 may receive, from the base station 102, the signaling indicating a communication of the uplink or downlink data channel.
[0095] In some implementations, the communication comprises: a downlink reception, an uplink transmission, an uplink retransmission, or at least one downlink or uplink repetition. The communication can be associated with PDCCH, PDSCH, PUCCH or PUSCH. In some implementations, the signaling is a radio resource control (RRC) message, a medium access control (MAC) control element (MAC CE) , or downlink control information (DCI) .
[0096] In some implementations, the communication is associated with a packet in higher layer, a code block in a physical layer, a code block group in a physical layer, a transport block (TB) in a physical layer, or a basic unit used to recover part of the information for the communication.
[0097] As shown in Fig. 3, the UE 104 may determine 320 an indicator associated with the data channel based on the signaling. The indicator may be to determine information for the communication. The base station 102 may determine 330 the indicator associated with the data channel based on the signaling. The UE 104 may perform 340 the communication based on the indicator. The base station 102 may perform 350 the communication based on the indicator.
[0098] In some implementations, the information for the communication is transmitted by a physical downlink shared channel (PDSCH) reception or physical uplink shared channel (PUSCH) transmission in a slot, a PDSCH reception in a number of slots or a number of symbols, a PUSCH repetition in a number of slots or a number of symbols, a nominal PUSCH transmission, an actual PUSCH transmission, or any combination of them.
[0099] In some implementations, the indicator may be used to determine the information related to output information of channel coding. In some implementations, the indicator may be a packet size threshold.
[0100] In some implementations, the information for the communication is divided into multiple parts, and at least one known bit is added to at least one part among the multiple parts or at least one bit of at least one part among the multiple parts is discarded based on determining that sizes of the multiple parts are different. The packet division may be at higher layer, or at physical layer, e.g. for different code block, for different code block group (CBG) , for different transport block (TB) .
[0101] For example, for semantic information, transmission packet division may consider a semantic information boundary, as shown in Fig. 4. If a semantic packet size is larger than a regular size, division may be performed considering the semantic information only, without multiplexing with other packet, some of bits of the semantic packet may be discarded so that a size is same as regular transmission packet. If a semantic packet size is smaller than a regular size, “0” or other known bits may be added to beginning or ending so that a size is same as regular transmission packet. With a packet contains semantic information only, specific processing can be performed, e.g. separate retransmission number, separate retransmission scheme for a semantic packet.
[0102] In some implementations, a size is used as an input parameter for training of a model to determine the information for the communication. The model may be an AI model. Different size may be associated with different structure or parameter of the AI model. One structure or parameter may be selected for a packet size. A size of a transmission packet may be used as an input to the AI model. In this way, the information generated / outputted by the AI model may approximately be the size of the transmission packet.
[0103] In some implementations, the indicator may indicate an index of a model or a functionality to determine information for the communication. For example, for scheduled PUSCH or PDSCH, the indicator may be an explicit indication (e.g. in DCI) , e.g. “0” indicates index #0 and “1” indicates index #1. As another example, for semi-persistent scheduling (SPS) PDSCH or a semi-static PUSCH (e.g. configured grant (CG) type 1, CG type 2) , the indicator may be configured by RRC or MAC CE.
[0104] In some implementations, the index of the model or the functionality may be different for each retransmission of the data channel.
[0105] In some implementations, the indicator may indicate multiple indices of models or functionalities. The information based on the multiple indices may be in a packet generated by high layer and transmitted to physical layer. The packet size may be small, and it may be transmitted in a single PDSCH or PUSCH, and it may not need concatenation of multiple packets to recover the original information.
[0106] In some implementations, the information for the communication may be based on output information of the model. In some implementations, the output information may be also be referred to as semantic packet.
[0107] In some implementations, sizes of output information of different models may be same. As shown in Fig. 5, for first transmission with a model #0, a semantic packet #2 (version #0) may be 7 bits. For retransmission #1 with a model #1, a semantic packet #2 (version #1) may also be 7 bits. For retransmission #2 with a model #2, a semantic packet #2 (version #2) may also be 7 bits. In some implementations, values of bits of each output information may be different due to different algorithms or model parameters or model structures of different index.
[0108] In some implementations, sizes of output information of different models are different. As shown in Fig. 6, for first transmission with a model #0, a semantic packet #2 (version #0) may be 7 bits. For retransmission #1 with a model #1, a semantic packet #2 (version #1) may be 9 bits. For retransmission #2 with a model #2, a semantic packet #2 (version #2) may be 11 bits. It is to be understood that different sizes of output information mean different compression rates. In other words, different index of models may be related to different compression rates. Introducing more redundancy bits may improve decoding accuracy at receiver side.
[0109] In some implementations, the output information of different models may have a common part. In some implementations, output information of a model with a lowest index may be the common part. In some implementations, the information for the communication may be a differential part of the output information of the model with respect to output information of a model with a lower index. As shown in Fig. 7, a semantic packet #2 (version #0) 710 with a model #0 is a common part. A 1st transmission packet 715 is all of the semantic packet #2 (version #0) . A semantic packet #2 (version #1) 720 with a model #1 has a common part (i.e. the semantic packet #2 (version #0) ) and a differential part with respect to the semantic packet #2 (version #0) . A 2nd transmission packet 725 is the differential part. A semantic packet #2 (version #2) 730 with a model #2 has a differential part with respect to the semantic packet #2 (version #1) . A 3rd transmission packet 735 is the differential part. It is to be understood that association between the output information of different models may be guaranteed by training of the corresponding neutral network. It may apply to each PDSCH transmission or retransmission, or each PUSCH transmission or retransmission, each PDSCH repetition, each slot for PUSCH repetition type A, or nominal or actual repetition for PUSCH repetition type B.
[0110] In some other implementations, the information for the communication may be a differential part of the output information of the model with respect to the common part. As shown in Fig. 8, a semantic packet #2 (version #0) 810 with a model #0 has a common part and a dedicated part. A 1st transmission packet 815 is all of the semantic packet #2 (version #0) . A semantic packet #2 (version #1) 820 with a model #1 has a common part and a differential part with respect to the common part. A 2nd transmission packet 825 is the differential part. A semantic packet #2 (version #2) 830 with a model #2 has a common part and a differential part with respect to the common part. A 3rd transmission packet 835 is the differential part. It is to be understood that association between the output information of different models may be guaranteed by training of the corresponding neutral network. It may apply to each PDSCH transmission or retransmission, or each PUSCH transmission or retransmission, each PDSCH repetition, each slot for PUSCH repetition type A, or nominal or actual repetition for PUSCH repetition type B.
[0111] In some implementations, the index of the model is determined based on some information carried by the signaling. For example, the information can include a repetition index identifier, redundancy version information, a time, frequency or code domain resource index, a coreset pool index, a reference signal (RS) port index, an RS set index, an RS index, a code division multiplexing (CDM) group index, or any combination thereof.
[0112] In some implementations, the index of the model may be implicitly determined based on a hybrid automatic repeat request (HARQ) process identifier and a new data indicator (NDI) bit in the signaling. In some implementations, the index of the model is determined based on a number of changed NDI bits with a same HARQ process identifier. The UE 104 may count the number of changes of NDI to determine the index of retransmission times, and then determine the index of the model based on an index of the retransmission times. For example, for a certain HARQ process identifier, the index of the model is equal to the index of the retransmission times. In some implementations, it may apply for downlink reception, for example, of PDSCH transmission or retransmission. In some implementations, the HARQ process identifier and the NDI is in DCI. In some implementations, the UE 104 may receive from the base station 102, a signaling (e.g. RRC or MAC CE) configuring whether to use the HARQ process identifier and the NDI to determine the index of the model. In other words, the signaling may configure how to interpret existing bits in DCI. In some implementations, it may apply for downlink reception. In some implementations, it may apply for uplink transmission, retransmission or repetition.
[0113] In some other implementations, the index of the model may be implicitly determined based on a HARQ process identifier and redundancy version (RV) information in the signaling. The UE 104 may determine the index of the model based on an RV index with same HARQ process identifier. For example, for a certain HARQ process identifier, the index of the model is equal to the RV index. In some implementations, it may apply for downlink reception, for example, of PDSCH transmission or retransmission or PDSCH repetition. In some implementations, it may apply for uplink transmission, retransmission or repetition.
[0114] In some other implementations, for PUSCH repetition, the index of the model may be based on a RV index of a PUSCH. For PUSCH repetition type A, each index may be associated with PUSCH transmission in a slot. For PUSCH repetition type B, each index may be associated with a nominal or actual PUSCH transmission in several symbols. For PDSCH repetition, the index of the model may be based on a RV index. For example, if the RV index for 4 PUSCH repetitions are 0, 2, 3, 1 respectively, then the model index for the 4 corresponding repetitions may also be model#0, model#2, model#3, model#1, respectively.
[0115] In some implementations, for PDSCH repetition, in multi-TRP scenario, different TCI state or coreset pool index may be associated with PDSCH in different frequency, time, or code domain resources. The different PDSCH in time, frequency, or code domain may be associated with different index of models or functionalities. An index of a model or functionality for a PDSCH may be determined by a corresponding frequency, time, code domain resource index, or any combination of the indexes. For example, for frequency division multiple (FDM) case, there may be a first PDSCH associated with upper frequency domain resource, and a second PDSCH associated with lower frequency domain resource. The first PDSCH may be associated with an index #0 of a model or functionality and the second PDSCH may be associated with an index #1 of a model or functionality. As another example, for time division multiple (TDM) case, there may be a first PDSCH associated with 1st and 3rd time slot, and a second PDSCH associated with 2nd and 4th time slot. The first PDSCH may be associated with an index #0 of a model or functionality and the second PDSCH may be associated with an index #1 of a model or functionality. For example, for code division multiple (CDM) case, there may be a first PDSCH associated with CDM group#1 and / or TCI state#1, and a second PDSCH associated with CDM group#2 and / or TCI state#2. The first PDSCH may be associated with an index #0 of a model or functionality and the second PDSCH may be associated with an index #1 of a model or functionality.
[0116] It is to be understood that for each transmission, the UE 104 may firstly determine corresponding packet based on the index of the model, and then to determine an RV version based on legacy methods. A packet associated with an index may still have different RV version, different IR bits based on legacy scheme.
[0117] In some implementations, the UE 104 may determine whether to perform the communication based on the index of the model or the functionality or to perform the communication based on the indicator which is used to determine the information related to output information of channel coding.
[0118] In some implementations, the determination may be in accordance with receiving a signaling indicating usage of the indicator. In some other implementations, the determination may be in accordance with different procedures. In some implementations, the determination may be in accordance with whether the communication is related to an initial access procedure or a data communication in an RRC connected state. For example, legacy HARQ scheme is used for initial access procedure, and a scheme of the present disclosure is used for PDSCH or PUSCH transmission in RRC connected state. In some other implementations, the determination may be in accordance with whether the communication is related to a HARQ in a physical layer or an ARQ in a higher layer. For example, legacy HARQ scheme is used for physical layer retransmission, and a scheme of the present disclosure is used for high layer ARQ based retransmission. In some other implementations, the determination may be in accordance with a transmission or retransmission index, or a repetition index. For example, legacy HARQ scheme is used for odd index of retransmission (e.g. 1st or 3rd retransmission) , and a scheme of the present disclosure is used for even index of retransmission (e.g. 2nd or 4th retransmission) . In some other implementations, the determination may be in accordance with the traffic associated with the communication. For example, legacy HARQ scheme is used for URLLC, and a scheme of the present disclosure is used for eMBB. In some other implementations, the determination may be in accordance with different signal to interference plus noise ratio (SINR) values. For example, legacy HARQ scheme is used for a relatively higher SINR value, and a scheme of the present disclosure is used for a relatively lower SINR value.
[0119] In some implementations, for uplink transmission, the UE 104 may transmit, to the base station 102, a parameter related to: a compression ratio, a model index, a data set index, a functionality index, a parameter set index, or any combination thereof. The base station 102 may determine, based on the parameter, SINR, reception accuracy, or any combination thereof, whether to perform the communication based on the index of the model or the functionality or to perform the communication based on the indicator.
[0120] In some implementations, for downlink transmission, the base station 102 may transmit, to the UE 104, a parameter related to: a compression ratio, a model index, a data set index, a functionality index, a parameter set index, or any combination thereof. The UE 104 may determine, based on the parameter, SINR, reception accuracy, or any combination thereof, whether to perform the communication based on the index of the model or the functionality or to perform the communication based on the indicator.
[0121] So far, solutions of data channel communication are described in connection with the process 300. It is to be noted that operations or steps described in the process 300 may be carried out separately or in any suitable combinations.

In some implementations, the memory 904 may include, among other things, a basic I / O system (BIOS) which may control basic hardware or software operation such as the interaction with peripheral components or devices.
[0129] The I / O controller 908 may manage input and output signals for the device 900. The I / O controller 908 may also manage peripherals not integrated into the device M02. In some implementations, the I / O controller 908 may represent a physical connection or port to an external peripheral. In some implementations, the I / O controller 908 may utilize an operating system such as or another known operating system. In some implementations, the I / O controller 908 may be implemented as part of a processor, such as the processor 906. In some implementations, a user may interact with the device 900 via the I / O controller 908 or via hardware components controlled by the I / O controller 908.
[0130] In some implementations, the device 900 may include a single antenna 910. However, in some other implementations, the device 900 may have more than one antenna 910 (i.e., multiple antennas) , including multiple antenna panels or antenna arrays, which may be capable of concurrently transmitting or receiving multiple wireless transmissions. The transceiver 906 may communicate bi-directionally, via the one or more antennas 910, wired, or wireless links as described herein.

[0133] Fig. 10 illustrates an example of a processor 1000 for data channel communication in accordance with aspects of the present disclosure. The processor 1000 may be an example of a processor configured to perform various operations in accordance with examples as described herein. The processor 1000 may include a controller 1002 configured to perform various operations in accordance with examples as described herein. The processor 1000 may optionally include at least one memory 1004, such as L1 / L2 / L3 cache. Additionally, or alternatively, the processor 1000 may optionally include one or more arithmetic-logic units (ALUs) 1006.
