However, traditional control information indication methods are not suitable for AI-intelligent receivers. Therefore, for AI-intelligent receivers, how to eliminate unnecessary control information indications to reduce signaling overhead has become a technical problem that needs to be solved. Summary of the Invention

[0040] Figure 2 illustrates a schematic diagram of a network architecture 200 according to an embodiment of this application. This network architecture 200 describes the network architecture of a 5G NR / LTE / LTE-A system, which can also be referred to as a 5G system (5GS) / evolved packet system (EPS) network architecture. The network architecture 200 includes at least one of the following: network device 110, terminal device 120, 5G core network (5GC) / evolved packet core (EPC) 210, home subscriber server (HSS) / unified data management (UDM) 220, and Internet service 230.

[0042] Figures 3A and 3B respectively illustrate a schematic diagram of a wireless protocol stack structure according to an embodiment of this application. Figures 3A and 3B use a 5G wireless protocol stack as an example for illustration. The 5G wireless protocol stack is divided into two planes: the user plane (UP) protocol stack and the control plane (CP) protocol stack. The user plane protocol stack is the protocol suite used for user data transmission, and the control plane protocol stack is the protocol suite used for control signaling transmission in the 5G system. The specific names of each protocol stack layer are as follows:

[0043] As shown in Figure 3A, the user plane protocol stack includes, from top to bottom, the following layers: Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and Physical (PHY) layer.

[0044] As shown in Figure 3B, the control plane protocol stack includes, from top to bottom: non-access stratum (NAS); radio resource control (RRC) layer, PDCP layer, RLC layer, MAC layer, and PHY layer.

[0045] It should be understood that the different layers in the above protocol stack have different functions, and they work together through inter-layer interaction to achieve communication between terminal devices and network devices. With the development of artificial intelligence technology, AI-assisted computing has permeated the processing implementation methods of the above protocol stack. For example, the scheduling algorithm of the MAC layer and the encoding / decoding algorithm of the PHY layer can apply artificial intelligence algorithms to improve the performance of communication algorithms.

[0046] As an example, the wireless protocol architecture in Figures 3A and 3B is applicable to the first node in this application.

[0047] As an example, the wireless protocol architecture in Figures 3A and 3B is applicable to the second node in this application.

[0048] It should be understood that the interpretation of the terminology in the embodiments of this application may refer to the TS36, TS37 and TS38 series of specifications of the 3rd generation partnership project (3GPP), but may also refer to the specifications of the Institute of Electrical and Electronics Engineers (IEEE).

[0049] To facilitate understanding, some related technical knowledge involved in the embodiments of this application is first introduced. The following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0050] With the development of communication technology, AI technology is ushering in a new round of technological revolution in human society. As an important research direction of AI technology, machine learning (ML) utilizes the non-linear processing capabilities of deep neural networks (DNN) to successfully solve a series of problems that were previously difficult to handle. In fields such as image recognition, speech processing, natural language processing, and games, it has even demonstrated performance superior to humans, and therefore has received increasing attention recently.

[0051] With the continuous development of AI technology, wireless communication systems are also undergoing rapid advancements. For example, 5G mobile communication systems can support three major application scenarios: enhanced mobile broadband (eMBB), ultra-reliable low latency communication (uRLLC), and massive machine-type communications (mMTC). Future 6G and beyond wireless communication systems will evolve towards higher throughput, lower latency, higher reliability, greater connection numbers, and higher spectrum utilization. AI has significant application potential in many areas, including modeling and learning in complex and unknown environments, channel prediction, intelligent signal generation and processing, network state tracking and intelligent scheduling, and network optimization deployment, and is expected to promote the evolution of future communication paradigms and the transformation of network architecture. Thanks to breakthroughs in AI and computing technologies, communication systems are continuously developing towards intrinsic intelligence. As an example, researching AI-intrinsic 6G wireless air interfaces and wireless networking is of great significance and value.

[0052] Traditional wireless communication links primarily address the complexity of transmission links through module stacking and technology densification. The following explanation uses a 4G / 5G wireless communication link as an example, illustrated in Figure 4.

[0053] As shown in Figure 4, the transmitting end of the communication link consists of seven modules. These seven modules, in processing order, are: source encoder, channel encoder, modulation, demodulation reference signal (DMRS) insert, precoding and mapping, waveform generation, and digital predistortion (DPD). After processing by these modules, the transmitting end's antenna transmits the wireless channel to the receiving end via beam scanning. The receiving end's antenna then receives the signal via beam scanning.

[0054] Corresponding to the transmitting end, the receiving end mainly includes eight modules. In order of processing after channel reception, they are: radio frequency module, timing / carrier recovery module, de-mapping module, channel estimation module, channel equalization module, demodulation module, channel decoder module, and source decoder module.

[0055] As shown in Figure 4, the functional modules of a traditional communication link are designed and optimized independently. After a long period of exploration, each functional module has approached its theoretical limit, and further performance improvements result in a dramatic increase in complexity with minimal gains. In the design and optimization of some functional modules, in order to reduce design complexity, certain nonlinear processes are simplified and assumed to be linear operations. However, this linear approach limits the performance improvement of each module. Furthermore, the optimization of a module does not equate to the optimization of the entire link performance; modular design incurs performance losses.

[0056] In traditional 4G and 5G systems, downlink control information (DCI) is used to schedule downlink data channels, namely the physical downlink shared channel (PDSCH).

[0057] Optionally, the DCI may include a virtual resource block (VRB) to physical resource block (PRB) mapping to instruct the receiver's demapping module to perform resource demapping.

[0058] Optionally, the DCI may include the DMRS sequence initialization used by the transmitter to transmit data, which is used to instruct the receiver's channel estimation module and channel equalization module to perform channel estimation and equalization.

[0059] Optionally, the DCI may include modulation and coding scheme (MCS), redundancy version (RV), hybrid automatic repeat request (HARQ) process number, and multiple-input multiple-output (MIMO) information to instruct the receiver's demodulation and decoding modules to perform demodulation and decoding, respectively. The MCS in the DCI can be used to indicate the modulation scheme and coding scheme.

[0060] As one implementation, DCI can be implemented using a modulation and transport block size (TBS) index table corresponding to the PDSCH, as shown in Table 1. As shown in Table 1, the terminal device can use the MCS index (I... MCS Determine the modulation order (Q) used in the PDSCH. m ) and TBS index (I TBS ).

[0061] Table 1

[0062] The modulation order Q in Table 1 m =2 corresponds to the modulation scheme of quadrature phase shift keying (QPSK), Q m =4 corresponds to the modulation scheme 16QAM, one of the various quadrature amplitude modulation (QAM) schemes. m =6 corresponds to the 64QAM modulation scheme, Q m =8 corresponds to the 256QAM modulation scheme, Q m=10 corresponds to the 1024QAM modulation scheme. The TBS index in Table 1 and the number of allocated physical resource blocks are used together to determine the transport block size. Simultaneously, the TBS index can also implicitly correspond to the coding rate, i.e., determine the coding scheme.

[0063] As another implementation, DCI can indicate the modulation, target code rate, and spectral efficiency corresponding to PDSCH using Table 2. As shown in Table 2, the terminal device can use the MCS index (I... MCS Determine the modulation order (Q) used for transmission in the PDSCH. m ) and target coding rate (Rx).

[0064] Table 2

[0065] Combining Tables 1 and 2, the MCS in traditional DCI is 5 bits, which can indicate up to 32 combinations of modulation and coding schemes.

[0066] Optionally, the DCI used to schedule the uplink data channel, i.e., the physical uplink shared channel (PUSCH), may also include MCS, RV, and HARQ process numbers, which are used to instruct the transmitter to perform modulation and coding.

[0067] The preceding text, with reference to Figure 4, introduced the traditional wireless communication link and the control information used for scheduling the data channel. Thanks to the introduction of AI / ML technology, the performance of the communication link has been effectively improved. For example, replacing the module in Figure 4 with an AI / ML method can lead to performance improvements and reduced processing latency. Furthermore, AI / ML methods can be directly applied to air interface design.

[0068] In some embodiments, the application of AI / ML in the wireless physical layer may include data-driven and model-driven approaches.

[0069] For data-driven approaches, traditional deep learning networks are mostly based on data-driven methods. This approach uses a standard neural network structure as a black box and trains it with a large amount of data. Training a standard neural network requires not only a huge dataset but also a significant amount of training time and computing power. However, these resources are extremely scarce in some situations, especially in the field of wireless communication.

[0070] Model-driven approaches, which build network topologies based on known physical mechanisms and domain knowledge, require less training data and shorter training time, and have therefore become an effective means of achieving intelligent communication.

[0071] Therefore, researching model-driven deep learning for wireless physical layer design provides theoretical support and a technological direction for the development of intelligent communication in 6G. Optionally, there are three methods for constructing model-driven deep learning: forming a signal flow graph from iterative algorithms; using the algorithm as an initialization step and combining it with a neural network; and mimicking the traditional structure in model-driven methods. Currently, model-driven deep learning for wireless physical layer design has been extensively studied in areas such as large-scale MIMO channel estimation, signal detection, channel decoding, CSI feedback, and multi-user precoding.

[0072] AI / ML can be applied in various ways in the wireless physical layer. One approach is to use neural networks to replace basic functional modules in traditional transmitters and receivers. Another approach views physical layer communication as an end-to-end signal reconstruction problem. The concept of an autoencoder can be used to represent the physical layer communication process, and joint optimization of end-to-end communication can create AI-powered transmitters and receivers.

[0073] As an example, the AI / ML model can independently replace individual modules, such as individual modules, at the receiver and transmitter of the communication link.

[0074] As an example, AI / ML models can jointly replace multiple modules at the receiver and transmitter of a communication link.

[0075] In some embodiments, AI technology can enable AI-intelligent end-to-end joint transmission and reception. The end-to-end communication system can transform a traditional communication system into a data-driven framework, with the transmitter and receiver jointly trained based on an end-to-end loss function. As an example, the nonlinear loss caused by the RF DPD module can also be introduced into the AI-intelligent transmitter, and this RF nonlinear loss can be compensated for through end-to-end joint training. In this case, the transmitter does not need to send modulation scheme indication, DMRS indication, or MIMO indication to the AI-intelligent receiver.

[0076] For ease of understanding, the AI ​​smart transceiver applicable to the embodiments of this application will be described below with reference to Figures 5 to 7.

[0077] Figure 5 illustrates a possible implementation of a wireless communication link where individual modules of the receiver or transmitter can be independently replaced using AI / ML models. As shown in Figure 4, a traditional communication link receiver includes multiple modules, such as channel estimation, channel equalization, demodulation, and channel decoding. These modules can be independently replaced using AI / ML models, allowing for modular optimization to effectively adapt to relevant communication system architectures. This breaks the performance upper bound of traditional receiver algorithms and allows for better comparison and verification of the performance gains of AI / ML models.

[0078] As shown in Figure 5, the AI / ML model can replace at least one of the demodulation reference signal insertion module and the RF digital predistortion module at the transmitting end of the wireless communication link, thus becoming an AI intelligent transmitter. The AI / ML model can also replace at least one of the channel estimation module, channel equalization module, demodulation module, and channel decoding module at the receiving end of the wireless communication link, thus becoming an AI intelligent receiver.

[0079] Figure 6 shows a possible implementation of a wireless communication link that uses an AI / ML model to jointly replace multiple modules of the receiver.

[0080] As shown in Figure 6, the channel decoding module on the wireless communication link is replaced with a separate AI / ML model, while the channel estimation module, channel equalization module, and demodulation module are replaced with a unified AI / ML model. Since module-by-module optimization cannot achieve overall optimality, while multi-module collaborative optimization can maximize system gain, and in complex scenarios (such as interference scenarios), joint optimization can better leverage the advantages of AI in solving complex systems, resulting in greater gain.

[0081] Figure 7 illustrates a possible implementation of AI intelligent end-to-end joint transceiver. As shown in Figure 7, the modulation module, DMRS insertion module, precoding and mapping module, and waveform generation module at the transmitter are jointly designed as part of the AI ​​intelligent transmitter, while the demodulation module, channel equalization module, channel estimation module, demapping module, and waveform reception and processing module at the receiver are jointly designed as part of the AI ​​intelligent receiver. The nonlinear loss of the RF digital predistortion module is introduced into the AI ​​intelligent transmitter. Within the framework shown in Figure 7, the transmitter does not need to send modulation scheme indication, DMRS indication, and MIMO indication to the receiver.

[0082] In Figures 5 to 7, the waveform generation modules at the receiving and transmitting ends of the wireless communication link correspond to the waveform receiving and processing modules.

[0083] The preceding text, in conjunction with Figures 5 to 7, introduced various AI-powered intelligent receivers and transmitters. Compared to the traditional transceivers shown in Figure 4, AI-powered intelligent receivers can self-detect the information processed by each receiving module through AI / ML models. Therefore, by introducing AI-powered intelligent receivers, transmitters in future communication systems will no longer need to send at least a portion of the indication information from the downlink control information to the AI-powered intelligent receiver, thus saving significant signaling overhead.

[0084] However, the self-testing operation performed by the AI ​​smart receiver requires a large amount of data training, computing power, storage costs and processing capabilities. It also needs to meet various requirements such as data privacy, system requirements, application environment and compatibility, which puts high demands on the AI ​​smart receiver on the terminal device.

[0085] In summary, for AI-powered intelligent receivers, eliminating unnecessary control information instructions to reduce signaling overhead is a pressing technical problem that needs to be solved. Furthermore, considering the limitations of the terminal device's computing power, processing capabilities, and implementation requirements, balancing control information overhead and the processing complexity of the AI-powered intelligent receiver is also a technical problem that needs to be addressed. As an example, for AI-powered intelligent receivers, optimizing control information to achieve a balance between resource consumption and processing complexity is a technical issue that needs to be considered.

[0086] Based on this, this application proposes a method for a node in wireless communication. For a first node, it can receive first control signaling including a first indication field. The first indication field indicates a first information set, and a first subset of information in the first information set corresponds to a transmission mode of first data. Therefore, the first node can receive or send the first data according to this transmission mode. Through this method, the first indication field in the control signaling sent by the second node only indicates an information set including multiple information subsets. Since the information set provides some prior information, the complexity of blind demodulation and blind decoding by the first node using an AI / ML model can be reduced. Simultaneously, since only the information set is indicated, the number of bits in the first indication field is correspondingly reduced, which helps to reduce the overhead of control signaling and improve resource utilization efficiency.

[0087] For ease of understanding, the method for wireless communication in a node according to an embodiment of this application will be described in detail below with reference to Figure 8. Figure 8 is presented from the perspective of the interaction between the first node and the second node.

[0088] As an example, the first node can be a network-controlled repeater (NCR).

[0089] As an example, the first node can be a terminal device, such as the terminal device 120 shown in FIG1.

[0090] As an example, the first node can be a relay, such as a relay terminal.

[0091] As an example, the second node can be a network device, such as network device 110 shown in Figure 1.

[0092] As an example, the second node can be a base station.

[0093] In some embodiments, an AI / ML model or a similar model is deployed on the first node side. Based on the AI / ML model, the transceiver of the first node may include an AI intelligent receiver. This AI intelligent receiver can implement any type of intelligent reception, and is not limited thereto.

[0094] As an example, the type of AI smart receiver on the first node side is related to the functionality of the AI ​​model and / or ML model used.

[0095] As an example, the AI ​​intelligent receiver on the first node side uses an AI / ML model for demodulation.

[0096] As an example, the AI ​​intelligent receiver on the first node side uses an AI / ML model for decoding.

[0097] As an example, the AI ​​intelligent receiver on the first node side uses an AI / ML model for joint demodulation and decoding.

[0098] As an example, the AI ​​intelligent receiver on the first node side uses an AI / ML model for intelligent equalization and demodulation.

[0099] As an example, the AI ​​intelligent receiver on the first node side uses an AI / ML model for intelligent end-to-end joint transmission and reception.

[0100] In some embodiments, the capabilities of the first node may include its ability to perform wireless communication. For example, the capabilities of the first node may include its ability to receive and transmit wireless signals. Alternatively, the capabilities of the first node may include its predictive, computational, and / or processing capabilities after incorporating an AI / ML model. Furthermore, the capabilities of the first node may be related to the type of model used.

[0101] In some embodiments, an AI / ML model may or may not be deployed on the second node side; this is not a limitation.

[0102] The method shown in Figure 8 includes steps S810 and S820, which are described below.

[0103] In step S810, the first node receives the first control signaling. The first node can also receive the first control signaling sent by the second node.

[0104] The first control signaling can be any type of control signaling from the second node. In some embodiments, the first control signaling can be carried in different layers of the protocol stack. In some embodiments, the first control signaling can include signaling from any layer of the protocol stack.

[0105] As one embodiment, the first control signaling includes physical layer (PHY) signaling.

[0106] As an example, the first control signaling is physical layer signaling.

[0107] As one embodiment, the first control signaling includes downlink control information (DCI), or the first control signaling is DCI.

[0108] As one embodiment, the first control signaling includes sidelink control information (SCI), or the first control signaling is SCI.

[0109] As one embodiment, the first control signaling includes MAC layer signaling, or the first control signaling is MAC layer signaling.

[0110] As one embodiment, the first control signaling includes a MAC CE, or the first control signaling is a MAC CE.

[0111] As one embodiment, the first control signaling includes RRC layer signaling, or the first control signaling is RRC layer signaling.

[0112] As one embodiment, the first control signaling includes an RRC IE, or the first control signaling is an RRC IE.

[0113] As one embodiment, the first control signaling includes higher-layer signaling, or the first control signaling is higher-layer signaling.

[0114] In some embodiments, the first control signaling is carried on different downlink channels, that is, the first control signaling is transmitted on different channels.

[0115] As an example, the first control signaling is transmitted on the PDCCH.

[0116] In some embodiments, the first control signaling is transmitted based on a first control information format. When the second node transmits the first control signaling based on the first control information format, the processing flow of the first control signaling includes at least one of the following: the first control information format is attached with a cyclic redundancy check (CRC), CRC scrambling, (source) channel coding, rate matching, scrambling processing, modulation, and mapping to physical resources. For the first node, after detecting control signaling, it needs to determine whether the detected control signaling is the first control signaling through blind detection.

[0117] As an example, the processing flow of the first control signaling can refer to the DCI processing flow in the relevant 3GPP protocols. For instance, the processing flow of the first control signaling may include some or all of the processing flows described above in the control signaling processing flow.

[0118] As an example, in the above scrambling process, the radio network temporary identifier (RNTI) used for scrambling is the first RNTI. That is, the first control signaling is scrambled by the first RNTI.

[0119] As one example, after the first control information format is attached with a CRC, the first RNTI is used to scramble the CRC. This can also be understood as the first RNTI scrambling the first control signaling.

[0120] As an example, the processing flow of the first control signaling at the sending end and the detection flow at the receiving end can be seen in Figures 4 to 7.

[0121] As an example, the processing and detection procedures of the first control signaling are related to the functionality of the AI / ML model adopted by the first node.

[0122] As an example, the processing and detection procedures of the first control signaling are related to the intelligent receiving function adopted by the first node.

[0123] In some embodiments, the first node may detect one or more control signaling messages, including the first control signaling message, within a time window for monitoring control signaling. The first node needs to perform blind detection on all detected control signaling messages to determine the first control signaling message.

[0124] The first control signaling is used to schedule the first data. The first node can receive or send the first data based on the first control signaling. The transmission of the first data will be described in detail below in conjunction with step S820.

[0144] As one embodiment, when the first data is received by the first node, the first control signaling is used to schedule the first data, including the first control signaling being used to indicate the sidelink assignment index corresponding to the first data.

[0145] As one embodiment, when the first data is received by the first node, the first control signaling is used to schedule the first data, including the first control signaling being used to indicate the downlink assignment index corresponding to the first data.

[0146] As one embodiment, the first control signaling is used to schedule the first data, including the first control signaling being used to indicate the transmission configuration indication corresponding to the first data.

[0147] It should be understood that the first control signaling used to schedule the first data may also include other information used by the first control signaling to instruct the first data. This other information may be determined according to relevant 3GPP protocols.

[0148] In some embodiments, the second node sends a first control signaling based on a first control information format. This can be understood as the first control signaling including the first control information format, or the indication information included in the first control signaling being determined according to the first control information format.

[0149] As an example, the first control information format or the first control signaling may include at least one of the following indication fields: frequency domain resource allocation, time domain resource allocation, NDI, modulation and coding system, modulation system, coding method, redundancy version, HARQ process number, transmit power control, channel access type, CP extension, channel access type and CP extension, precoding information and layer number, second precoding information, antenna port, side-line allocation index, downlink allocation index, and transmission configuration indication.

[0150] In some embodiments, the first control information format can be adapted from a traditional control information format to accommodate the introduction of an AI intelligent receiver. For example, by incorporating an AI / ML model, a certain indication field in the traditional control information format can be adjusted to a first indication field with relatively low signaling overhead, thereby reducing signaling overhead. Furthermore, when the first node performs blind detection using the AI / ML model, some indication fields do not need to provide specific information (e.g., the specific transmission method of uplink or downlink data). These indication fields can be replaced by the first indication field of the indication information set. That is, the first indication field can provide only a portion of prior information, and the first node will combine it with the model for demodulation and decoding.

[0151] As an example, when the first control signaling is DCI, the format of the first control information can be determined according to one of DCI format 0_0, DCI format 0_1, DCI format 0_2, DCI format 0_3, DCI format 1_0, DCI format 1_1, DCI format 1_2, DCI format 1_3, DCI format 2_0, DCI format 2_1, DCI format 2_2, DCI format 2_3, DCI format 2_4, DCI format 2_5, DCI format 2_6, DCI format 2_7, DCI format 2_8, DCI format 2_9, DCI format 3_0, DCI format 3_1, DCI format 3_2, DCI format 4_0, DCI format 4_1, and DCI format 4_2.

[0152] As an example, when the first control signaling is DCI, the format of the first control information can be adjusted based on one of the following: DCI format 0_0, DCI format 0_1, DCI format 0_2, DCI format 0_3, DCI format 1_0, DCI format 1_1, DCI format 1_2, DCI format 1_3, DCI format 2_0, DCI format 2_1, DCI format 2_2, DCI format 2_3, DCI format 2_4, DCI format 2_5, DCI format 2_6, DCI format 2_7, DCI format 2_8, DCI format 2_9, DCI format 3_0, DCI format 3_1, DCI format 3_2, DCI format 4_0, DCI format 4_1, DCI format 4_2.

[0153] As one embodiment, the first control signaling includes a first indication field. The first indication field can be determined according to a first control information format. The first control information format can be determined based on the computing power, processing capabilities of the first node, and the functions of the AI ​​intelligent receiver.

[0154] In some embodiments, the first indication field can be used to indicate processing information of any one or more processing flows in the data processing flow of the transmitting end. As an example, to reduce signaling overhead, the first indication field in the first control information format or the first control signaling can indicate one or more of the following processing information: frequency domain resource allocation, time domain resource allocation, NDI, MCS, redundancy version, HARQ process number, precoding information and layer number, second precoding information, antenna port, MIMO indication, DMRS indication, waveform generation, modulation scheme, and coding method. As an example, the first indication field can replace any one or more of the indication fields corresponding to the above information.

[0155] As an example, the first indication field can be adjusted for any indication field in the DCI with a bit count greater than 1.

[0156] As an example, the first indication field can be used to indicate a combination of information from any number of indication fields in the DCI.

[0157] In some embodiments, the first indication field can be used to indicate any one or more pieces of information related to the transmission method of the first data. For example, the first indication field can indicate processing information of any one or more processing flows used by the sending end to transmit the first data.

[0158] As one embodiment, the first indication field can be any one or more indication fields related to the transmission method of the first data. For example, the first indication field can be used to indicate information related to one or more of the following: time-frequency resource allocation, NDI, MCS, modulation scheme, coding scheme, redundancy version, HARQ process number, transmit power control, channel access type and CP extension, side precoding information and layer number, second precoding information, antenna port, side line allocation index, downlink allocation index, and transmission configuration indication.

[0159] In some embodiments, when the first indication field is adjusted based on any other indication field, the first indication field can indicate a set of indication information corresponding to that other indication field, i.e., a first information set. As an example, the first indication field can be adjusted based on any other indication field. When that other indication field is used to indicate a transmission method, the first indication field can indicate the set of transmission methods to which that transmission method belongs. This set of transmission methods includes multiple transmission methods. That is, the first indication field can indicate a transmission method or a group of transmission methods related to data transmission, and the first information set is also called a first type of information set.

[0160] The first indication field indicates a first information set. The first information set may include one or more methods of any information related to the transmission method of the first data. When the first indication field indicates the first information set, the number of information that the first indication field needs to indicate is reduced, and the number of bits can be reduced accordingly. For example, the first information set includes multiple MCS information. Or, the first information set includes multiple HARQ process number information.

[0161] As one embodiment, when the first indication field is related to frequency domain resource allocation, the first information set can be a frequency domain resource allocation set. In this embodiment, the first information set may include at least one of the following: multiple carrier indications; multiple bandwidth portion indications; multiple frequency domain resource allocation indices; multiple frequency domain resource allocation types; and multiple frequency hopping flags.

[0162] As one embodiment, when the first indication field is related to time-domain resource allocation, the first information set can be a time-domain resource allocation set. In this embodiment, the first information set may include multiple time-domain resource allocation indices and / or multiple time-domain resource allocation types.

[0163] As one embodiment, when the first indication field is related to an MCS, the first information set can be an MCS set.

[0164] As an example, when the first indication field is related to the modulation scheme, the first information set can be a modulation scheme set. In this embodiment, the first information set may include at least one of the following: multiple modulation scheme indices; multiple modulation orders; multiple transport block sizes; multiple transport block size indices; the same modulation order and multiple transport block sizes; the same modulation order and multiple transport block size indices; a combination of multiple modulation orders and transport block sizes.

[0165] As one embodiment, when the first indication field is related to an encoding method, the first information set can be an encoding method set. In this embodiment, the first information set may include at least one of the following: multiple encoding methods; multiple encoding method indices; multiple encoding rates; multiple transport block sizes; multiple transport block size indices; the same encoding method and multiple encoding rates; the same encoding method and multiple transport block sizes; the same encoding method and multiple transport block size indices; a combination of multiple encoding methods and encoding rates; a combination of multiple encoding methods and transport block sizes.

[0166] As one embodiment, when the first indication field relates to a redundant version, the first information set can be a redundant version set. In this embodiment, the first information set may include multiple redundant versions and / or multiple redundant version indexes.

[0167] As one embodiment, when the first indication field is related to a HARQ process number, the first information set can be a set of HARQ process numbers. In this embodiment, the first information set may include multiple HARQ process numbers.

[0168] As one embodiment, when the first indication field is related to transmit power control, the first information set can be a transmit power control set. In this embodiment, the first information set may include multiple transmit power controls and / or multiple transmit power control indices.

[0169] As one embodiment, when the first indication field is related to channel access type and CP extension, the first information set can be a set of channel access types and CP extensions. In this embodiment, the first information set may include at least one of the following: multiple channel access types; multiple channel access type indices; multiple CP extensions; and multiple CP extension indices.

[0170] As one embodiment, when the first indication field is related to precoding information and the number of layers, the first information set can be a precoding set. In this embodiment, the first information set may include at least one of the following: multiple precoding indices; multiple precoding matrices; multiple precoding matrix indices; multiple precoding layer numbers; and multiple precoding layer number indices.

[0171] As one embodiment, when the first indication field is related to the second precoded information, the first information set can be the second precoded information set. In this embodiment, the first information set may include multiple second precoded information indices.

[0172] As an example, when the first indication field is related to an antenna port, the first information set can be an antenna port set. In this example, the first information set may include at least one of the following: multiple antenna port indices; multiple DMRS port(s) numbers; multiple DMRS port number indices; multiple numbers of front-load symbols; and multiple numbers of DMRS CDM group(s) without data.

[0173] As an example, when the first indication field is related to the side row allocation index, the first information set can be the side row allocation index set.

[0174] As an example, when the first indication field is related to the downlink allocation index, the first information set can be the downlink allocation index set.

[0175] As an example, when the first indication field is related to the transmission configuration indication, the first information set can be the transmission configuration indication set.

[0176] As one embodiment, when the first indication field is related to any of the above-mentioned multiple pieces of information, the first information set can be a corresponding information group set. For example, the first information set may include multiple redundant versions and multiple HARQ process numbers.

[0177] It should be understood that the above-described embodiment of the first information set is merely an example, and the first information set can also be other information sets related to one or more transmission methods of the first data. For example, the first information set can be determined according to relevant 3GPP protocols.

[0178] In some embodiments, the first information set is one of multiple information sets. The multiple information sets including the first information set can cover all parameters of one or a set of transmission methods related to the transmission of the first data. That is, the multiple information sets include all transmission parameters of the first data in that transmission method or set of transmission methods. The second node can determine the first information set from the multiple information sets based on the transmission method of the first data, thereby sending the first control signaling.

[0179] As an example, when the first information set is an MCS set, multiple information sets include all MCSs or all MCS indices.

[0180] In some embodiments, multiple information sets to which the first information set belongs can be represented by a list of first information sets. The list of first information sets can be indicated by first configuration information. This will be explained later with reference to Figure 9, and will not be elaborated upon hereafter.

[0181] In some embodiments, to indicate a first information set, a first indication field may indicate the index of the first information set among multiple information sets. For a transmission mode or a group of transmission modes, the number of information sets is much smaller than the number of information items themselves; therefore, the upper limit of the index that the first indication field needs to indicate is much lower than the upper limit of the index that directly indicates information or a combination of information items. For example, the original MCS indication field requires 5 bits to indicate a combination of 32 modulation schemes and encoding methods, while the MCS set indication field may only need 3 bits to indicate 8 MCS sets.

[0182] In the above embodiments, the first information set index is used to indicate the index of the first information set among multiple information sets. That is, the first indicator field can indicate the first information set through the first information set index. For example, when the first information set is an MCS set, the first indicator field can indicate the MCS set index.

[0183] In some embodiments, the first information set index is related to the number of bits in the first indicator field or the number of multiple information sets.

[0184] In some embodiments, the number of bits in the first indicator field is related to the amount and type of information that the first indicator field needs to indicate. When the amount of information corresponding to the first indicator field is large, the number of bits in the first indicator field is high. Therefore, when the information indicated by the first indicator field is changed from specific information to a set of information, the amount of information corresponding to the first indicator field decreases, and the number of bits in the first indicator field can be reduced accordingly.

[0185] In some embodiments, the first indication field is used to indicate a first information set among a plurality of information sets. The number of the plurality of information sets is related to the number of bits in the first indication field. The number of the plurality of information sets is also referred to as the quantity of the plurality of information sets.

[0186] As one embodiment, the number of multiple information sets is related to the number of bits in the first indication field, including the number of multiple information sets used to determine the number of bits in the first indication field.

[0187] As one embodiment, the number of multiple information sets is related to the number of bits in the first indicator field, including the correspondence between the number of multiple information sets and the number of bits in the first indicator field.

[0188] As an example, when the first indication field is adjusted based on one or more indication fields in conventional control signaling, the number of bits in the first indication field is less than the number of bits in the single indication field or less than the sum of the number of bits in the multiple indication fields.

[0189] As an example, when the first indicator field is associated with an MCS set, the number of bits in the first indicator field is less than 5.

[0190] As an example, when the first indicator field is used to indicate the MCS set index, the number of bits in the first indicator field can be less than the number of bits in the original MCS indicator field. In traditional DCI, the MCS is 5 bits, used to indicate a maximum of 32 combinations of modulation and coding schemes. However, with the introduction of AI smart receivers, these 32 combinations of modulation and coding schemes are divided into multiple MCS sets, each containing various combinations of modulation and coding schemes. Therefore, the number of MCS sets is much less than 32. When DCI uses the first indicator field only to indicate the MCS set index, the number of bits in the first indicator field can be less than the number of bits in the original MCS indicator field.

[0191] For example, when the first indicator field indicates the MCS set index, the first control signaling does not need to include a 5-bit MCS indicator field. Furthermore, the number of bits D in the first indicator field can be any positive integer less than 5. For example, D = 1 bit, D = 2 bits, or D = 3 bits. Since the 5-bit MCS index in the DCI is replaced by a 1-bit, 2-bit, or 3-bit MCS set index, the overhead of the DCI is greatly reduced. Especially in the case of multiple transport blocks, the signaling overhead of the MCS index (5 bits) for each transport block is reduced.

[0192] As an example, when the first indicator field is related to the HARQ process number set, the number of bits in the first indicator field is less than 4.

[0193] As an example, when the first indication field relates to a set of precoded information, the number of bits in the first indication field is less than 6.

[0194] As an example, when the first indicator field is associated with a set of redundant versions, the number of bits in the first indicator field is less than 2.

[0195] As an example, the number of bits in the first indication field is one of 1, 2, or 3.

[0196] In some embodiments, the number of multiple information sets is related to the amount of information contained in each information set. The division of multiple information sets needs to ensure coverage of all parameters of a transmission mode or a set of transmission modes. Therefore, when the amount of information contained in each information set increases, the number of multiple information sets decreases; when the amount of information contained in each information set decreases, the number of multiple information sets increases.

[0197] In some embodiments, the number of multiple information sets is related to at least one of the computing power, model type, and processing capability of the first node. That is, the number of multiple information sets is determined based on at least one of the computing power, model type, and processing capability of the first node.

[0198] As an example, the number of multiple information sets is determined based on two of the first node's computing power, model type, and processing capability.

[0199] As one embodiment, the number of the plurality of information sets depends on at least one of the computing power, model type, and processing capability of the first node.

[0200] As an example, the number of multiple information sets depends on two of the first node's computing power, model type, and processing capabilities.

[0201] As an example, at least one of the computing power, model type, and processing capability of the first node is used to determine the number of the plurality of information sets.

[0202] As an example, two of the first node's computing power, model type, and processing capability are used to determine the number of multiple information sets.

[0203] In the above embodiments, two of the computing power, model type and processing capability of the first node are, for example, the computing power and model type of the first node, or the computing power and processing capability of the first node, or the model type and processing capability of the first node.

[0204] As an example, the higher or greater the computing power of the first node, the smaller the number of the multiple information sets.

[0205] As an example, the lower or smaller the computing power of the first node, the greater the number of the multiple information sets.

[0206] As one example, the computing power of the first node is negatively correlated with the number of multiple information sets. When the computing power of the first node is strong, the first information set can include a large number of pieces of information, and the number of multiple information sets is small. When the computing power of the first node is weak, the first information set can include a small number of pieces of information, and the number of multiple information sets is large.

[0207] As an example, the model type of the first node is related to the number of multiple information sets. On one hand, the model type of the first node is used to determine the parameter type indicated by the first indicator field. For example, the model of the first node can be used during demodulation and decoding, where the first indicator field indicates an MCS set or an MCS set index. The number of multiple information sets is related to the parameters of the MCS. On the other hand, the model type of the first node can also determine the processing capability of the first node.

[0208] As an example, the higher the level corresponding to the model type of the first node, the fewer the number of the multiple information sets.

[0209] As an example, the lower the level corresponding to the model type of the first node, the greater the number of the multiple information sets.

[0210] As an example, the stronger the processing capability of the first node, the smaller the number of the multiple information sets.

[0211] As an example, the weaker the processing power of the first node, the greater the number of the multiple information sets.

[0212] As an example, the processing power of the first node is negatively correlated with the number of multiple information sets. If the first node can perform complex reasoning, the first information set can include more information, and the number of multiple information sets is relatively small. If the first node cannot perform complex reasoning, the first information set can only include less information, and the number of multiple information sets is relatively large.

[0213] The preceding text introduced various embodiments of the first information set. The following explanation uses the MCS set as an example. The MCS set indicated by the first indication field may include at least one MCS. That is, the first indication field does not directly indicate the MCS of the first data, but rather indicates an information set including multiple MCSs. The intelligent receiver of the first node can determine the MCS of the first data based on this information set and inference.

[0214] As an example, when the first indication field is adjusted based on the indication field corresponding to the MCS, the first indication field can indicate an MCS set index. The first node can determine the MCS set corresponding to the first data based on the index of the information set, and then determine the MCS of the first data, i.e., the transmission mode of the first data, through reasoning.

[0215] As an example, when the first indication field indicates an MCS collection index, the format of the first control information can be as shown in Table 3.

[0216] Table 3

[0217] Table 3 shows a DCI format for AI smart receivers. The first control signaling can include or be determined based on this DCI format. In Table 3, the first indication field included in the first control signaling is the Modulation-Coding System Set Index, i.e., the MCS set index. The first indication field uses D bits for indication, meaning the number of bits in the first indication field is D. The value of D can be determined based on the number of MCS sets, i.e., D depends on the number of MCS sets.

[0218] Since the first indication field in Table 3 is used to indicate the MCS set index, the first control signaling no longer includes the MCS indication field. It should be noted that Table 3 only uses the MCS indication field in the DCI as an example. Besides the MCS indication field, other indication fields in the DCI can also use a similar method, dividing multiple parameters or multiple indices into multiple sets, becoming set indices. Regardless of which indication field in the DCI, since it only indicates the index of the information set, the number of bits in the first indication field can be reduced accordingly, thereby reducing control signaling overhead.

[0219] Furthermore, when the receiver at the first node performs blind detection using an AI / ML model, the computational complexity of the AI / ML model on the first node side can be reduced while saving signaling overhead, based on partial prior information from the information set. For example, after the receiver at the first node receives the MCS set index, it then performs blind demodulation and decoding using the AI / ML model. Since the MCS set index provides partial prior information, the complexity of blind demodulation and decoding by the AI / ML model can be reduced.

[0220] Furthermore, when the first indication field in the first control signaling adopts the method of indicating a set of information, even if the number of bits is reduced, the amount of information indicated by the first indication field can be greater than the amount of information in the indication field before adjustment. For example, the MCS in traditional DCI is 5 bits, used to indicate a maximum of 32 combinations of modulation and coding schemes. When the first indication field adopts the method of indicating a set of MCS, the number of combinations of modulation and coding schemes that can be indicated can be more than 32.

[0221] Taking the first indicator field indicating the MCS collection index as an example, the following examples, in conjunction with Tables 4 to 8, illustrate the methods for determining multiple information sets. It should be noted that Tables 4 to 8 are examples of MCS collection index tables, not limitations.

[0222] In some embodiments, the first information set may include multiple sub-indexes, each corresponding to a multiple information subset index. As one example, the multiple information subsets correspond one-to-one with the multiple sub-indexes. That is, each sub-index in the first information set corresponds to one information subset.

[0223] For example, when any MCS set index indicated by the first indicator field can correspond to multiple MCS indices, as shown in Tables 4 and 5.

[0224] Table 4

[0225] Table 4 shows an MCS set index table for PDSCH with a 2-bit indicator field. As shown in Table 4, the 32 MCS indices are divided into 4 MCS sets. The first indicator field can indicate the first MCS set, i.e., the first information set, to the first node through the 2-bit MCS set index.

[0226] Table 5

[0227] Table 5 shows an MCS set index table for PDSCH with 5 bits in the indicator field. As shown in Table 5, the 32 MCS indices are divided into 8 MCS sets. The first indicator field can indicate the first MCS set, i.e., the first information set, to the first node through the 3-bit MCS set index.

[0228] As one example, the first information set may include multiple sub-indexes, and the first information set index may be related to the maximum or minimum index value among the multiple sub-indexes. For example, the multiple MCS set indexes in Table 4 are sorted based on the minimum sub-index value.

[0229] In some embodiments, the first information set may include a combination of multiple different transmission parameters. The first information set includes multiple information subsets, and any subset of information may include multiple sub-information items. One sub-information item may correspond to one transmission parameter. The index of the first information set corresponding to the first information set is determined based on the combination of at least two sub-information items among the multiple sub-information items.

[0230] As an example, in the first information set, the parameters of at least one of the at least two sub-information combinations are fixed. That is, in multiple subsets of the first information set, at least one sub-information is the same. This same sub-information can be used as prior information for the first node to perform blind decoding and blind demodulation in conjunction with the AI / ML model.

[0231] For example, when the first information set is an MCS set, the first information set may include multiple combinations of modulation orders and transport block sizes. The MCS set index indicated by the first indication field can correspond to different combinations of modulation orders and transport block sizes, as shown in Table 6.

[0232] Table 6

[0233] Table 6 shows another MCS set index table for PDSCH with an indicator field of 2 bits. As shown in Table 6, various combinations of modulation order and transport block size indices are used to divide the data into 4 MCS sets. The modulation order of any one of the 4 MCS sets is a fixed value. For example, the modulation order corresponding to MCS set index 0 is 2. The first indicator field can indicate the first MCS set, i.e., the first information set, to the first node through the 2-bit indicated MCS set index.

[0234] For example, when the first information set is an MCS set, the first information set may include combinations of multiple modulation orders and coding rates. The MCS set index indicated by the first indicator field may correspond to multiple combinations of modulation orders and coding rates, as shown in Tables 7 and 8.

[0235] Table 7

[0236] Table 7 shows another MCS set index table for PDSCH with an indicator field of 2 bits. As shown in Table 7, various combinations of modulation order and target coding rate are divided into 4 MCS sets. The modulation order of any MCS set in the 4 MCS sets is a fixed value. For example, the modulation order corresponding to MCS set index 1 is 4. The first indicator field can indicate the first MCS set, i.e., the first information set, to the first node through the 2-bit indicated MCS set index.

[0237] Table 8

[0238] Table 8 shows an MCS set index table for PDSCH with a 1-bit indicator field. As shown in Table 8, various combinations of modulation order and target coding rate are divided into two MCS sets. One MCS set contains multiple modulation orders and multiple target coding rates, while the other MCS set contains a fixed modulation order and multiple target coding rates. For example, MCS set index 0 corresponds to modulation orders 2 and 4. The first indicator field can indicate the first MCS set, i.e., the first information set, to the first node through a 1-bit MCS set index.

[0239] As shown in Tables 6 to 8, when the first indication field in the first control signaling uses the method of indicating the MCS set for indication, the first indication field can indicate more than 32 combinations of modulation and coding methods.

The first information subset within these multiple information subsets corresponds to the transmission mode of the first data.

[0270] As an example, the transmission method of the first data corresponding to the first information subset means that the first information subset can be used to determine at least one transmission parameter of the first data. For example, the first information subset can be used to determine the MCS of the first data.

[0271] As an example, any one of the plurality of information sets includes at least one subset of information.

[0272] The first information set includes a first information subset. Since the first information subset corresponds to the transmission mode of the first data, the first node can determine the first information subset through the first information set in the first control signaling, and thus determine the transmission mode of the first data.

[0273] In some embodiments, after receiving the first control signaling, the first node can determine a first information set including one or more information subsets based on the first indication field. The first node can determine the first information subset, i.e., the transmission mode of the first data, based on prior information in the first information set.

For example, the transmission parameters of the first data may also include other transmission parameters in 3GPP related protocols.

[0311] In some embodiments, the first subset of information may include at least one of the aforementioned multiple transmission parameters. It should be understood that the first subset of information may also include any other transmission parameter related to the transmission method of the first data.

[0312] In some embodiments, the sub-information included in the first information subset is determined based on the transmission parameters corresponding to the first information set. That is, the transmission mode information included in the first information subset is related to the content of the first indication field.

Accordingly, the first information subset can also include one or more other information. One or more information can be determined according to relevant 3GPP protocols.

[0320] In some embodiments, the first information set includes one or more information subsets. The first information subset is one of the one or more information subsets included in the first information set. Each information subset in the first information set can directly correspond to a data transmission method.

[0345] The preceding text, with reference to Figure 8, described an embodiment of a method for indicatively indicating a first data transmission mode based on an information set in the first control signaling received by the first node. In some scenarios, the second node can also send an information set list to the first node, allowing the first node to determine the first information set based on the first information set index in the first control signaling. As one implementation, the information set list can be indicated through configuration information. For ease of understanding, the following text, with reference to Figure 9, provides an exemplary description of a method for the second node to send configuration information to the first node.

The first information set list includes multiple information sets to which the first information set belongs; that is, the first information set list is used to indicate multiple information sets that include the first information set.

[0348] As one embodiment, the first configuration information is used to indicate multiple information sets including the first information set. That is, the first configuration information may not indicate a list of first information sets, but may directly indicate multiple information sets.

[0396] Figure 13 is a schematic diagram of the hardware modules of the communication device provided in an embodiment of this application. Specifically, Figure 13 shows a block diagram of a first communication device 1350 and a second communication device 1310 communicating with each other in the access network.

[0397] The first communication device 1350 includes a controller / processor 1359, a memory 1360, a data source 1367, a transmitting processor 1368, a receiving processor 1356, a multi-antenna transmitting processor 1357, a multi-antenna receiving processor 1358, a transmitter / receiver 1354, and an antenna 1352.

[0398] The second communication device 1310 includes a controller / processor 1375, a memory 1376, a data source 1377, a receiver processor 1370, a transmitter processor 1316, a multi-antenna receiver processor 1372, a multi-antenna transmitter processor 1371, a transmitter / receiver 1318, and an antenna 1320.

[0399] In the transmission from the second communication device 1310 to the first communication device 1350, at the second communication device 1310, upper-layer data packets from the core network or from the data source 1377 are provided to the controller / processor 1375. The core network and data source 1377 represent all protocol layers above the L2 layer. The controller / processor 1375 implements the functionality of the L2 layer. In the transmission from the second communication device 1310 to the first communication device 1350, the controller / processor 1375 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation for the first communication device 1350 based on various priority metrics. The controller / processor 1375 is also responsible for retransmitting lost packets and signaling to the first communication device 1350. The transmit processor 1316 and the multi-antenna transmit processor 1371 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 1316 performs encoding and interleaving to facilitate forward error correction at the second communication device 1310, and mapping of signal clusters based on various modulation schemes (e.g., binary phase shift keying, quadrature phase shift keying, M-phase shift keying, M-quadrature amplitude modulation). Multi-antenna transmit processor 1371 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing to generate one or more spatial streams. Transmit processor 1316 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 1371 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 1318 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 1371 into an radio frequency stream, which is then provided to different antennas 1320.

[0400] In the transmission from the second communication device 1310 to the first communication device 1350, at the first communication device 1350, each receiver 1354 receives a signal through its corresponding antenna 1352. Each receiver 1354 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 1356. The receiver processor 1356 and the multi-antenna receiver processor 1358 implement various signal processing functions of Layer 1. The multi-antenna receiver processor 1358 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 1354. The receiver processor 1356 uses a fast Fourier transform to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 1356, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 1358 after multi-antenna detection to recover any spatial stream destined for the first communication device 1350. Symbols on each spatial stream are demodulated and recovered in the receive processor 1356, generating soft decisions. The receive processor 1356 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted by the second communication device 1310 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 1359. The controller / processor 1359 implements the functions of Layer 2. The controller / processor 1359 may be associated with a memory 1360 storing program code and data. The memory 1360 may be referred to as computer-readable media. In the transmission from the second communication device 1310 to the first communication device 1350, the controller / processor 1359 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover the upper-layer data packets from the second communication device 1310. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0401] In the transmission from the first communication device 1350 to the second communication device 1310, at the first communication device 1350, upper-layer data packets are provided to the controller / processor 1359 using a data source 1367. The data source 1367 represents all protocol layers above the L2 layer. Similar to the transmission functions at the second communication device 1310 described in the transmission from the second communication device 1310 to the first communication device 1350, the controller / processor 1359 implements header compression, encryption, packet segmentation and reordering, and multiplexing between the logical and transport channels, implementing L2 layer functions for the user plane and control plane. The controller / processor 1359 is also responsible for retransmitting lost packets and signaling to the second communication device 1310. Transmit processor 1368 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 1357 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 1368 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 1357, the stream is provided to different antennas 1352 via transmitter 1354. Each transmitter 1354 first converts the baseband symbol stream provided by multi-antenna transmit processor 1357 into a radio frequency symbol stream before providing it to antenna 1352.

[0402] In the transmission from the first communication device 1350 to the second communication device 1310, the function at the second communication device 1310 is similar to the receiving function at the first communication device 1350 described in the transmission from the second communication device 1310 to the first communication device 1350. Each receiver 1318 receives radio frequency signals through its corresponding antenna 1320, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 1372 and the receiving processor 1370. The receiving processor 1370 and the multi-antenna receiving processor 1372 jointly implement the L1 layer function. The controller / processor 1375 implements the L2 layer function. The controller / processor 1375 may be associated with a memory 1376 that stores program code and data. The memory 1376 may be referred to as computer-readable media. In the transmission from the first communication device 1350 to the second communication device 1310, the controller / processor 1375 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover the upper-layer data packets from the first communication device 1350. The upper-layer data packets from the controller / processor 1375 can be provided to the core network or all protocol layers above Layer 2, and various control signals can also be provided to the core network or Layer 3 for Layer 3 processing.
