[0067] 1. Synchronization Signals for 5th-Generation Mobile Communication Technology (5G) New Radio (NR)

[0068] The SSB in the 5G NR design can include the PSS, SSS, PBCH, and the PBCH's reference signal (DMRS). The PSS and SSS are used to carry cell identifiers (IDs) (capable of carrying 1008 cell IDs), achieve time-frequency synchronization, and obtain timing information. The PSS, SSS, and PBCH's reference signal (DMRS) can be used to measure cell or beam signal strength / quality. The PBCH can carry beam and cell information. Overall, the 5G NR SSB structure is shown in Figure 2. The SSB consists of the PSS, SSS, and PBCH. The SSB occupies four symbols in the time domain: the PSS is the first symbol within the SSB, the SSS is the third symbol within the SSB, and the PBCH is the second, fourth, and part of the third symbol within the SSB. The SSB spans 20 resource blocks (RBs) in the frequency domain. It is important to note that in the 5G NR SSB design, the PSS, SSS, PBCH, and PBCH's DMRS all occupy independent time-frequency resources.

[0069] 2. Artificial Intelligence

[0070] In recent years, artificial intelligence research represented by neural networks has achieved great results in many fields, and it will play an important role in people's production and life for a long time to come.

[0071] The basic structure of a simple neural network consists of an input layer, hidden layers, and an output layer, as shown in Figure 3. The input layer receives data, the hidden layers process it, and the output layer produces the final result. Each node represents a processing unit, which can be thought of as simulating a neuron. Multiple neurons form a layer of a neural network. Multiple layers of information transmission and processing create a complete neural network.

[0072] With the continuous development of neural network research, neural network deep learning algorithms have been proposed in recent years. More hidden layers have been introduced, and feature learning has been performed layer by layer through multi-hidden layer neural network training, which has greatly improved the learning and processing capabilities of neural networks. It has also been widely used in pattern recognition, signal processing, optimization combination, anomaly detection and other aspects.

[0073] Similarly, with the development of deep learning, convolutional neural networks have also been further studied. The basic structure of a convolutional neural network includes an input layer, multiple convolutional layers, multiple pooling layers, a fully connected layer, and an output layer, as shown in Figure 4. The introduction of convolutional and pooling layers effectively controls the rapid increase in network parameters, limits the number of parameters, exploits the characteristics of local structures, and improves the robustness of the algorithm.

[0074] Problems with the use of SSB (including synchronization signals, broadcast messages, and DMRS for broadcast messages) involve the following aspects:

[0075] (1) Within the SSB, the detection accuracy of synchronization sequences such as PSS and SSS needs to be improved, especially the single detection accuracy. Only by ensuring and improving the detection accuracy of the synchronization signal can the normal execution of functions such as cell discovery, synchronization, and access be effectively guaranteed. However, if the above functions are completed by increasing the SSB resource overhead, such as more time domain resources, frequency domain resources, and longer synchronization sequences, the SSB, which originally occupies a large amount of independent transmission resources, will require even greater resource overhead. The solution of the embodiment of the present application considers the introduction and capability improvement of artificial intelligence / machine learning (AI / ML) receivers, and addresses the above problems through the matching design of SSB, such as shortening the required sequence time-frequency resources but ensuring the normal execution of the above cell discovery, synchronization, and access functions, and avoiding the independent occupation of a large amount of resources.

[0076] (2) Within the SSB, the PBCH part is currently included, which is mainly used to carry cell broadcast information. The time-frequency resources currently occupied by the PBCH, excluding the time-frequency resources occupied by the DMRS (demodulation reference signal of the PBCH) within the PBCH, are also limited in terms of the resources available for carrying the PBCH content. Problems such as the limited carrying resources of the PBCH are also issues that need to be addressed in the design of future communication systems. After considering the introduction of the AI / ML receiver, the solution of the embodiment of the present application can provide a solution that considers the sharing of resources of the cell information and cell synchronization signal (reference signal) carried on the PBCH. The resource sharing solution proposed in the embodiment of the present application can increase the available resources of the PBCH without incurring excessive system resource overhead.

[0077] (3) Considering that SSB is associated with beams, as the frequency increases and the number of beams increases, the number of SSBs that need to be transmitted within an SSB transmission cycle will also increase. For example, currently a maximum of 8 SSBs are required in low-frequency designs, and a maximum of 64 SSBs are required in high-frequency designs to meet the coverage and access requirements of the cell through beam scanning. However, with the commercialization of 5G, the preparation for 6G, and the evolution of subsequent wireless systems, there will inevitably be a demand for cell synchronization signal transmission at higher frequencies. Continuing to use the current SSB design method will bring more SSB beam scanning requirements. In other words, the SSB resource overhead within an SSB transmission cycle will be a problem that needs to be solved in the design of future communication systems. If the utilization rate of limited transmission resources within a single SSB, or between the cell synchronization signal and the cell broadcast signal involved in the initial access process, is not high, the overhead related to the synchronization signal (reference signal) and broadcast message involved in the overall cell access will be extremely large.

[0078] In summary, the communication method provided in the embodiments of the present application includes a method for designing a sixth-generation mobile communication technology (6th-Generation Mobile Communication Technology, 6G) synchronization signal. Taking into account the use of receiving and detection schemes represented by artificial intelligence / machine learning (AI / ML) receivers, through the design of a resource sharing scheme, beneficial effects can be obtained in terms of resource overhead required for 6G synchronization, cell information content carrying, and other issues.

[0079] FIG5 is a schematic flow chart of a communication method 500 according to an embodiment of the present application. The method can optionally be applied to the system shown in FIG1 , but is not limited thereto. The method includes at least part of the following contents.

[0080] S510. A first communications device transmits a reference signal and first data, where the reference signal is superimposed on a transmission resource of the first data.

[0081] In an embodiment of the present application, a first communications device may transmit a reference signal and first data to a second communications device via superimposed transmission resources. The first communications device may be a network device, such as a base station, and the second communications device may be a terminal device, such as a UE. The network device may transmit the reference signal and the first data to the terminal device via superimposed transmission resources. In one scenario, the network device may send notification information to the terminal device to inform the terminal device of the superimposed transmission type of the reference signal and the first data supported by the network device. In another scenario, the terminal device may send notification information to the network device to inform the network device of the superimposed transmission type of the reference signal and the first data supported by the terminal device. The first communications device may be a terminal device, such as UE1, and the second communications device may be another terminal device, such as UE2. One terminal device may transmit the reference signal and the first data to another terminal device via a sidelink via superimposed transmission resources. For example, UE1 may send notification information to UE2 to inform UE2 of the superimposed transmission type of the reference signal and the first data supported by UE1. UE2 may send notification information to UE1 to inform UE1 of the superimposed transmission type of the reference signal and the first data supported by UE2.

[0082] In one embodiment, the reference signal may include one or more of a synchronization signal, a primary synchronization signal, and a secondary synchronization signal.

[0083] In one embodiment, the first data includes a broadcast message. A broadcast message may also be referred to as broadcast information or broadcast data. For example, the first data includes cell broadcast data. Cell broadcast data may also be referred to as a cell broadcast message, cell broadcast information, or cell broadcast signal.

[0084] In one embodiment, the cell broadcast data includes at least one of cell information, Master Information Block (MIB) information, and System Information Block (SIB) information carried on the PBCH channel. The SIB information may include SIB1 information, SIB2 information, SIB3 information, SIB4 information, SIBx information, etc.

[0085] In the embodiment of the present application, by superimposing the transmission reference signal and the first data, the resource overhead occupied by the transmission can be reduced compared with the case where the transmission signal and the first data independently occupy different time-frequency resources.

[0086] In one implementation, the reference signal is completely or partially overlapped with the transmission resource of the first data.

[0087] In one embodiment, the transmission resources include time domain resources and / or frequency domain resources, the time domain resources include symbols, and the frequency domain resources include carriers.

[0088] In one embodiment, the carriers occupied by the reference signal and the first data in different symbols are completely identical, partially identical, or different. For example, the time domain resources of the reference signal occupy symbols 1, 2, and 3, and the first data occupies 24 identical carriers in symbols 1, 2, and 3. For another example, the time domain resources of the reference signal occupy symbols 1, 2, and 3, the first data occupies 12 carriers in symbol 1, and 24 carriers including the 12 carriers in symbols 2 and 3. For another example, the time domain resources of the reference signal occupy symbols 1, 2, and 3, the first data occupies carriers 1 to C6 in symbol 1, and occupies carriers 8 to C12 in symbol 2.

[0089] In one embodiment, the reference signal completely overlaps with the time domain resources and / or frequency domain resources of the first data. For example, the time domain resources of the reference signal and the first data both occupy symbols 1, 2, and 3. The frequency domain resources of the reference signal and the first data both occupy carrier 1 and carrier 2.

[0090] In one embodiment, the reference signal is partially superimposed with the time domain resources and / or frequency domain resources of the first data. In an embodiment of the present application, the time-frequency resources occupied by the transmission of the reference signal may not be exclusive, but may be shared with other signals and information transmissions. Therefore, adding more time domain symbols of reference signals (such as synchronization signals) will not bring additional resource overhead and system throughput loss while improving the accuracy of cell discovery, synchronization, measurement, etc. For example, the time domain resources of the reference signal occupy symbol 1, symbol 2, and symbol 3, and the time domain resources of the first data occupy symbol 1. The frequency domain resources of the reference signal occupy carrier 1 and carrier 2, and the frequency domain resources of the first data occupy carrier 2.

[0091] In one embodiment, the time domain resources of the reference signal and the first data completely overlap, and the frequency domain resources of the reference signal and the first data partially overlap. For example, the time domain resources of the reference signal and the first data occupy symbol 1, symbol 2, and symbol 3. The frequency domain resources of the reference signal occupy carrier 1 and carrier 2, and the frequency domain resources of the first data occupy carrier 2.

[0092] In one embodiment, the frequency domain resources of the reference signal and the first data are completely superimposed, and the time domain resources of the reference signal and the first data are partially superimposed. In an embodiment of the present application, the time-frequency resources occupied by the transmission of the reference signal may not be exclusive, but may be shared with other signals and information transmissions. Therefore, adding more time domain symbols of reference signals (such as synchronization signals) will not bring additional resource overhead and system throughput loss while improving the accuracy of cell discovery, synchronization, measurement, etc. For example, the time domain resources of the reference signal occupy symbol 1, symbol 2, and symbol 3, and the time domain resources of the first data occupy symbol 1. The frequency domain resources of the reference signal occupy carrier 1 and carrier 2, and the frequency domain resources of the first data occupy carrier 2. For example, the time domain resources of the reference signal occupy symbol 1, symbol 2, and symbol 3, and the time domain resources of the first data occupy symbol 1. The frequency domain resources of the reference signal and the first data occupy carrier 1 and carrier 2.

[0093] In one embodiment, the reference signal includes a first reference signal, and the first reference signal and the first data occupy exactly the same or partially the same time domain resources and / or frequency domain resources. This ensures that the frequency domain resources occupied by the transmission of the reference signal (e.g., a synchronization signal) are not exclusive and can be shared with other signals and information transmissions, without incurring additional resource overhead and system throughput loss. For example, the first reference signal and the first data occupy exactly the same time domain resources. For another example, the first reference signal and the first data occupy partially the same time domain resources. For another example, the first reference signal and the first data occupy exactly the same frequency domain resources. For another example, the first reference signal and the first data occupy partially the same frequency domain resources. For another example, the first reference signal and the first data occupy exactly the same time domain resources and frequency domain resources. For another example, the first reference signal and the first data occupy exactly the same time domain resources and partially the same frequency domain resources. For another example, the first reference signal and the first data occupy partially the same time domain resources and exactly the same frequency domain resources.

[0094] In one embodiment, the reference signal includes a second reference signal and a third reference signal, the second reference signal and the first data occupy exactly the same or partially the same time domain resources and / or frequency domain resources, and the third reference signal and the first data occupy exactly the same or partially the same time domain resources and / or frequency domain resources. For example, the second reference signal and the first data occupy exactly the same time domain resources and / or frequency domain resources, and the third reference signal and the first data occupy exactly the same time domain resources and / or frequency domain resources. For another example, the second reference signal and the first data occupy exactly the same time domain resources and / or frequency domain resources, and the third reference signal and the first data occupy partially the same time domain resources and / or frequency domain resources. For another example, the second reference signal and the first data occupy partially the same time domain resources and / or frequency domain resources, and the third reference signal and the first data occupy exactly the same time domain resources and / or frequency domain resources.

[0095] In one embodiment, the second reference signal and the third reference signal occupy different time domain resources, the second reference signal and the first part of the first data occupy exactly the same or partially the same time domain resources and / or frequency domain resources, and the third reference signal and the second part of the first data occupy exactly the same or partially the same time domain resources and / or frequency domain resources. The first and second parts of the first data may together constitute the first data, or may account for a certain proportion of the first data. For example, the second reference signal and the third reference signal occupy different time domain resources, the second reference signal and the first part of the first data occupy exactly the same time domain resources and frequency domain resources, and the third reference signal and the second part of the first data occupy exactly the same time domain resources and frequency domain resources. For another example, the second reference signal and the third reference signal occupy different time domain resources, the second reference signal and the first part of the first data occupy partially the same time domain resources and exactly the same frequency domain resources, and the third reference signal and the second part of the first data occupy exactly the same time domain resources and frequency domain resources. For another example, the second reference signal and the third reference signal occupy different time domain resources, the second reference signal and the first part of the first data occupy exactly the same time domain resources and frequency domain resources, and the third reference signal and the second part of the first data occupy partially the same time domain resources and exactly the same frequency domain resources. For another example, the second reference signal and the third reference signal occupy different time domain resources, the second reference signal and the first part of the first data occupy partially the same time domain resources and frequency domain resources, and the third reference signal and the second part of the first data occupy partially the same time domain resources and frequency domain resources.

[0096] In one embodiment, the second reference signal and the third reference signal occupy different frequency domain resources, the second reference signal and the third part of the first data occupy exactly the same or partially the same time domain resources and / or frequency domain resources, and the third reference signal and the fourth part of the first data occupy exactly the same or partially the same time domain resources and / or frequency domain resources. The third and fourth parts of the first data may together constitute the first data, or may account for a certain proportion of the first data.

For another example, the first reference signal, the fourth reference signal, and the first data occupy partially the same time domain resources and exactly the same frequency domain resources.

[0098] In one embodiment, the reference signal includes a second reference signal, a third reference signal, and a fourth reference signal, and the second reference signal, the third reference signal, the fourth reference signal, and the first data occupy exactly the same or partially the same time domain resources and / or frequency domain resources. For example, the second reference signal, the third reference signal, the fourth reference signal, and the first data occupy exactly the same time domain resources.

For another example, the second reference signal, the third reference signal, the fourth reference signal, and the first data occupy partially the same time domain resources and exactly the same frequency domain resources.

[0099] In one embodiment, the reference signal includes a fourth reference signal, and the fourth reference signal and the first data occupy exactly the same or partially the same time domain resources and / or frequency domain resources. For example, the fourth reference signal and the first data occupy exactly the same time domain resources.

[0100] In one embodiment, the first reference signal is a synchronization signal. In the embodiment of the present application, the transmission resources of the synchronization signal and the first data may be partially or completely overlapped.

[0101] In one embodiment, the second reference signal is a primary synchronization signal, and the third reference signal is a secondary synchronization signal. In this embodiment of the present application, the transmission resources of the primary synchronization signal, the secondary synchronization signal, and the first data may be partially or fully overlapped.

[0102] In one embodiment, the fourth reference signal is a demodulation reference signal. In this embodiment of the present application, the demodulation reference signal and the transmission resource of the first data may be partially or fully superimposed. The primary synchronization signal, the secondary synchronization signal, the demodulation reference signal, and the transmission resource of the first data may be partially or fully superimposed.

[0103] In one embodiment, another reference signal and / or the first data are superimposed and transmitted on one or more resource subsets within the resource range occupied by a reference signal. In an embodiment of the present application, the resource range occupied by the reference signal may include a time domain range and / or a frequency domain range. The resource subset may include a time domain resource subset and / or a frequency domain resource subset. For example, the time domain range occupied by a reference signal R1 is symbol 1 to symbol 6, and the frequency domain range is carrier 1 to carrier 3. A resource subset includes 2 symbols and 1 carrier. Another reference signal R2 is transmitted on the first resource subset, and the time domain resources occupied by the first resource subset are symbol 1 and symbol 2, and the frequency domain resources are carrier 1. The first data is transmitted on the second resource subset, and the time domain resources occupied by the second resource subset are symbol 3 and symbol 4, and the frequency domain resources are carrier 1.

[0104] In one embodiment, within the resource element (RE) where the reference signal and the first data are superimposed, REs are reserved and / or configured for non-superimposed transmission of the measurement reference signal, synchronization signal, and DMRS signal. For example, the transmission resources where the reference signal and the first data are superimposed include symbols 1 to 10 and carriers 1 to 12. Within the superimposed transmission resources, some REs can be reserved and / or configured as non-superimposed transmission resources. For example, the REs consisting of symbol 2 and carrier 3, and the REs consisting of symbol 3 and carrier 4 are non-superimposed transmission resources. Only one signal can be transmitted on the non-superimposed transmission resources.

[0105] In one embodiment, one or more reference signals are superimposed and transmitted on one or more resource subsets within the resource range occupied by first data. For example, the resource range occupied by the first data includes symbols 1 to 20 and carriers 1 to 24. A resource subset includes one symbol and two carriers. Reference signal R1 is transmitted on the first resource subset, where the time domain resources occupied by the first resource subset are symbol 1 and the frequency domain resources are carriers 1 and 2. Reference signal R2 is transmitted on the second resource subset, where the time domain resources occupied by the second resource subset are symbol 3 and the frequency domain resources are carriers 1 and 2.

[0106] In one embodiment, the resource subset on which the reference signal and the first data are superimposed is an RE subset, or only the resource subset of the first data is transmitted within the reference signal. For example, within the resource range occupied by the first data, a resource subset includes one RE, and one RE includes one symbol and one carrier. The reference signal R1 is transmitted on the first resource subset {RE1, RE2, RE3}, and the time domain resource occupied by RE1 is symbol 1, and the frequency domain resource is carrier 1; the time domain resource occupied by RE2 is symbol 2, and the frequency domain resource is carrier 2; the time domain resource occupied by RE3 is symbol 3, and the frequency domain resource is carrier 3. For another example, within the resource range occupied by the first data, there is a resource subset such as {RE4, RE5} that only transmits the first data and does not transmit the reference signal. The time domain resource occupied by RE4 is symbol 1, and the frequency domain resource is carrier 2; the time domain resource occupied by RE5 is symbol 2, and the frequency domain resource is carrier 3.

[0107] In one embodiment, the one or more resource subsets include at least one of a subset in the time domain, a subset in the frequency domain, a continuous subset, and a non-continuous subset. For example, a resource subset includes a continuous symbol subset {symbol 1, symbol 2, symbol 3} in the time domain. For another example, a resource subset includes a non-continuous symbol subset {symbol 1, symbol 3, symbol 5} in the time domain. For another example, a resource subset includes a continuous carrier subset {carrier 1, carrier 2, ..., carrier 12} in the frequency domain. For another example, a resource subset includes a non-continuous carrier subset {carrier 1, carrier 2, carrier 5, carrier 6, carrier 9, carrier 10} in the frequency domain.

[0108] In one embodiment, the reference signal and the first data are transmitted continuously or discontinuously on time domain resources and / or frequency domain resources. For example, the reference signal and the first data are transmitted continuously on time domain resources. For another example, the reference signal and the first data are transmitted continuously on frequency domain resources. For another example, the reference signal and the first data are transmitted discontinuously on time domain resources. For another example, the reference signal and the first data are transmitted discontinuously on frequency domain resources. For another example, the reference signal and the first data are transmitted continuously on time domain resources and discontinuously on frequency domain resources. For another example, the reference signal and the first data are transmitted discontinuously on time domain resources and continuously on frequency domain resources. For another example, the reference signal and the first data are transmitted continuously on both time domain resources and frequency domain resources. For another example, the reference signal and the first data are transmitted discontinuously on both time domain resources and frequency domain resources.

[0109] In one embodiment, the transmission power ratio occupied by the reference signal and the first data is a specific ratio. For example, the reference signal accounts for 10% of the total transmission power, and the first data accounts for 90% of the total transmission power. The total transmission power can be the transmission power corresponding to one or more REs, the transmission power corresponding to one or more symbols, or the transmission power corresponding to one or more carriers.

[0110] In one embodiment, the transmission power occupied by the reference signal and the first data on one RE is limited based on a power ratio.

[0111] In one embodiment, the transmission power occupied by the reference signal on the RE in the transmission resource is a first proportion of the total power of the REs in the transmission resource. In an embodiment of the present application, the first proportions corresponding to the reference signal and the first data may be the same or different. The first proportions corresponding to different reference signals may be the same or different. For example, the transmission power of the second reference signal occupies 10% of the total transmission power of an RE, the transmission power of the third reference signal occupies 20% of the total transmission power of an RE, and the first data occupies 70% of the total transmission power. For another example, the transmission power of the first reference signal occupies 10% of the total transmission power of an RE, the transmission power of the fourth reference signal occupies 10% of the total transmission power of an RE, and the first data occupies 80% of the total transmission power.

[0143] For a specific example of the second communication device executing the method 600 of this embodiment, reference may be made to the relevant description of the second communication device in the above method 500 , which will not be repeated here for the sake of brevity.

[0144] In the early stages of 5G standardization discussions, the term Synchronization Signal Block (SSB) was used. Since SSB also includes the PBCH channel (including broadcast messages carried on the PBCH and the DMRS signal of the PBCH), in the later specification writing process, for the sake of accuracy, it was renamed the Synchronization Signal Block / PBCH Block (SS / PBCH Block). For simplicity, it is generally referred to as SSB. The solution of the embodiment of the present application is a design centered around synchronization signals and broadcast channels, and SSB can be used to simply refer to synchronization signals and / or broadcast channels.

[0145] The reference signal described in the embodiments of the present application may be a synchronization signal and / or a demodulation reference signal, and may be further subdivided into one or more reference signals such as a synchronization signal, a primary synchronization signal, a secondary synchronization signal, and a demodulation reference signal. For example:

[0146] (1) The reference signal described in the embodiments of the present application may be a first reference signal, which is a synchronization signal;

[0147] (2) The reference signal described in the embodiments of the present application may be a second reference signal and a third reference signal, the second reference signal being a primary synchronization signal and the third reference signal being a secondary synchronization signal;

[0148] (3) The reference signals described in the embodiments of the present application may be a first reference signal and a fourth reference signal, the first reference signal being a synchronization signal and the fourth reference signal being a demodulation reference signal;

[0149] (4) The reference signals described in the embodiments of the present application may be a second reference signal, a third reference signal, and a fourth reference signal, wherein the second reference signal is a primary synchronization signal, the third reference signal is a secondary synchronization signal, and the fourth reference signal is a demodulation reference signal;

[0150] (5) The reference signal described in the embodiment of the present application may be a fourth reference signal, which is a demodulation reference signal.

[0151] The first data described in the embodiments of the present application may be cell broadcast data, such as MIB information, or SIB information (such as SIB1 information, SIB2 information, SIB3 information, SIB4 information, SIBx information, etc.).

[0152] The reference signal (eg, synchronization signal) and the first data (cell broadcast data, eg, cell broadcast data carried on the PBCH channel) are transmitted on overlapping transmission resources (completely overlapping or partially overlapping), sent by the base station, and received by the UE.

[0153] The technical basis of the scheme design in the embodiment of the present application is: after the introduction of the AI / ML receiver, it has been proved through experiments that the AI / ML receiver can realize separate or joint analysis of the superimposed transmitted reference signal and the first data, so that the resource exclusivity and excessive resource overhead of different signals and data in the SSB can be avoided by superimposing the transmitted reference signal and the first data, while ensuring the normal execution of the cell discovery, synchronization, measurement, cell information acquisition and other functions involved in the SSB.

[0154] The solution of the embodiment of this application mainly includes the following contents:

[0155] 1. The reference signal (e.g., synchronization signal) and the first data (cell broadcast data, e.g., cell broadcast data carried on the PBCH channel) can be transmitted on the same transmission resources, e.g., on the same time domain and / or frequency domain resources, for example, by superimposing the transmission synchronization signal and the cell broadcast data on the PBCH channel.

[0156] 2. The transmission of a reference signal (e.g., a synchronization signal) and first data (cell broadcast data, such as cell broadcast data carried on a PBCH channel) on the same transmission resource may include full overlay transmission or partial overlay transmission. Transmission modes include two-layer overlay transmission and multi-layer overlay transmission, as described in the following examples.

[0157] 3. The transmission power ratio occupied by the reference signal and the first data is a specific ratio. For example, the transmission power of the reference signal and the first data on the RE is limited, for example, there are power ratio restrictions respectively. For example, the power occupied by the reference signal on the RE is a specific ratio of the total RE power, such as 0.1%, 0.2%, 0.5%, 1%, 2%, 5%, 10%, 20%, 25%, 33%, 40%, 50%, 60%, 66%, 70%, 75%, 80%, 90%, 95%, 99%, etc.

[0158] 4. The time domain resources and frequency domain resources involved in all examples can be continuous resources or non-continuous resources.

[0159] Example 1: Fully Overlapping Design

[0160] A reference signal (e.g., a synchronization signal) and first data (cell broadcast data, such as cell broadcast data carried on the PBCH channel) are superimposed and transmitted on N symbols and M carriers, forming an SSB transmission scheme and SSB format for superimposed transmission of the synchronization signal and the broadcast message, as shown in Figure 7.

[0161] For example, the N symbols can be one or more symbols in a time slot, such as: 1 symbol, 2 symbols, 3 symbols, 4 symbols, 5 symbols, 6 symbols, 7 symbols, 8 symbols, 9 symbols, 10 symbols, 11 symbols, 12 symbols, 13 symbols, and 14 symbols. It can be symbols in multiple time slots, all symbols in multiple time slots, or some symbols in multiple time slots. In the solution of this example, because it is technically guaranteed that the time-frequency resources occupied by the transmission of reference signals (such as synchronization signals) are not exclusive and can be shared with other signals and information transmissions, adding more reference signal (such as synchronization signal) time domain symbols will not bring additional resource overhead and system throughput loss while improving the accuracy of cell discovery, synchronization, measurement, etc.

[0162] For example, among the M carriers, M can be a positive integer, such as 1 carrier, 4 carriers, 12 carriers, 24 carriers, 32 carriers, 48 ​​carriers, 64 carriers, 96 carriers, 128 carriers, 144 carriers, etc. For another example, if the influence of the DC carrier is considered, the M carriers can be 3 carriers, 11 carriers, 23 carriers, 31 carriers, 47 carriers, 63 carriers, 95 carriers, 127 carriers, 143 carriers, etc. For another example, the M carriers are carriers belonging to M_RB RBs, for example, M_RB can be 1 RB, 2 RBs, 4 RBs, 6 RBs, 8 RBs, 10 RBs, 12 RBs, 16 RBs, 20 RBs, 22 RBs, or 24 RBs. Similarly, in the solution of this example, because it is technically guaranteed that the frequency domain resources occupied by the transmission of the reference signal (such as the synchronization signal) are not exclusive, it can share resources with other signals and information transmissions, and will not bring additional resource overhead and system throughput loss.

[0163] A specific example is shown in Figure 8. Within the time-frequency resources of 144 carriers and 4 symbols, the synchronization signal and broadcast message (PBCH channel) also occupy the above resources to transmit the synchronization signal and cell broadcast information respectively, forming an SSB transmission scheme and SSB format in which the synchronization signal and broadcast message are superimposed and transmitted.

[0164] It should be noted that in the above design, the frequency domain resources occupied by the superimposed transmitted reference signal (synchronization signal) and the first data (cell broadcast data, such as cell broadcast data carried on the PBCH channel) on different symbols may be different. For example, the frequency domain resources occupied by the nth superimposed transmitted reference signal and the first data symbol are M_n subcarriers. For different symbols n, there may be different values ​​of M_n. n is a positive integer from 1 to N. M_n can be a positive integer, for example, it can be 1 carrier, 4 carriers, 12 carriers, 24 carriers, 32 carriers, 48 ​​carriers, 64 carriers, 96 carriers, 128 carriers, 144 carriers, etc.; or if the influence of the DC carrier is considered, the M_n carriers can be 3 carriers, 11 carriers, 23 carriers, 31 carriers, 47 carriers, 63 carriers, 95 carriers, 127 carriers, 143 carriers, etc. Or M_n carriers are carriers belonging to M_RB RBs, for example, M_RB can be 1 RB, 2 RBs, 4 RBs, 6 RBs, 8 RBs, 10 RBs, 12 RBs, 16 RBs, 20 RBs, 22 RBs, or 24 RBs.

[0165] A specific example is shown in Figure 9. The first superimposed symbol occupies 127 subcarriers, the second, third, and fourth superimposed symbols occupy 144 subcarriers, and the synchronization signal and broadcast message (PBCH channel) also occupy the above resources to superimpose the transmission of the synchronization signal and cell broadcast information, forming an SSB transmission scheme and SSB format for superimposed transmission of the synchronization signal and broadcast message.

[0166] It should be noted that the reference signal (synchronization signal) and the first data (cell broadcast data, such as cell broadcast data carried on the PBCH channel) superimposed and transmitted in the above design can be continuous or discontinuous in time domain resources, and can be continuous or discontinuous in frequency domain resources.

[0167] When a reference signal is used for synchronization, increasing its time span helps achieve better synchronization, such as better Doppler estimation. Based on the above considerations, when designing a synchronization signal and a broadcast message (PBCH channel) that occupy the same resources to transmit the synchronization signal and cell broadcast information, respectively, P groups of non-contiguous symbols can be used in the time domain to form a time-domain non-contiguous SSB format in which the synchronization signal and broadcast message are superimposed and transmitted, as shown in Figure 10. Each of the P groups of non-contiguous symbols consists of one or more symbols, such as one or two symbols. Each of the P groups of non-contiguous symbols is separated by one or more symbols, such as K1 symbols, where K1 is a positive integer, such as 1, 2, 3, 4, 5, 6, 7, 8, 14, 28, etc.

[0168] Three specific examples are shown in Figure 11. For example, there are two groups of symbols, each group of symbols occupies two symbols, and there are two symbols between the two groups of symbols; for another example, there are four groups of symbols, each group of symbols occupies one symbol, and there is one symbol between two adjacent groups of symbols; for another example, there are two groups of symbols, each group of symbols occupies one symbol, and there is one symbol between two adjacent groups of symbols; each group of symbols transmits synchronization signals and broadcast messages superimposed on the same time-frequency resources.

[0169] When reference signals are used for synchronization and channel estimation, increasing the span in the frequency domain helps achieve better synchronization. For example, this allows for better frequency offset and channel estimation. Based on the above considerations, when designing a synchronization signal and a broadcast message (PBCH) channel to occupy the same resources for transmission, respectively, Q groups of non-contiguous carriers can be used in the frequency domain to form a frequency-domain non-contiguous SSB format for superimposed transmission of the synchronization signal and the broadcast message, as shown in Figure 12. Each group of Q non-contiguous carriers consists of one or more carriers, such as one, two, four, or six carriers. Each group of Q non-contiguous carriers is separated by one or more carriers, such as K2 carriers, where K2 is a positive integer, such as 1, 2, 3, 4, 6, or 12. Each group of Q non-contiguous carriers consists of one or more RBs, such as one, two, four, or six RBs. There are Q groups of non-contiguous carriers, each of which is separated by one or more RBs, for example, by K2 RBs, where K2 is a positive integer, for example, K2 is 1, 2, 3, 4, 6, 12, etc.

[0170] Furthermore, considering the aforementioned design considerations of non-continuous time and frequency domains, the method of transmitting a reference signal (e.g., a synchronization signal) and first data (e.g., cell broadcast information) on the same time-frequency resources also includes: for one SSB, non-continuous transmission in both the time and frequency domains, as shown in Figure 13 . Based on the aforementioned considerations, the synchronization signal and the broadcast message (PBCH channel) occupy the same resources to transmit the synchronization signal and cell broadcast information, respectively. Regarding transmission resources: In the time domain, P groups of non-continuous symbols can be utilized, where each group of symbols in the P groups of non-continuous symbols consists of one or more symbols, such as one or two symbols. Each group of symbols in the P groups of non-continuous symbols is separated by one or more symbols, such as K1 symbols, where K1 is a positive integer, such as 1, 2, 3, 4, 5, 6, 7, 8, 14, 28, etc. In the frequency domain, Q groups of non-continuous carriers can be utilized, where each group of carriers in the Q groups of non-continuous carriers consists of one or more carriers, such as one carrier, two carriers, four carriers, or six carriers. Q groups of non-contiguous carriers are separated by one or more carriers, for example, by K2 carriers, where K2 is a positive integer and can be 1, 2, 3, 4, 6, or 12. Each group of carriers in Q groups of non-contiguous carriers consists of one or more RBs, for example, 1, 2, 4, or 6 RBs. Each group of carriers in Q groups of non-contiguous carriers is separated by one or more RBs, for example, by K2 RBs, where K2 is a positive integer and can be 1, 2, 3, 4, 6, or 12.

[0171] Example 2: Superposition Design with Multiple Reference Signals

[0172] The reference signal described in Example 1 may be a synchronization signal and / or a demodulation reference signal. Specifically, the reference signal may be: a synchronization signal, a primary synchronization signal, a secondary synchronization signal, a demodulation reference signal, or other reference signals, one or more of which may be included, for example:

[0173] (1) The reference signal described in this example may be a first reference signal, which is a synchronization signal;

[0174] (2) The reference signal described in this example may be a second reference signal and a third reference signal, the second reference signal being a primary synchronization signal and the third reference signal being a secondary synchronization signal;

[0175] (3) The reference signals described in this example may be a first reference signal and a fourth reference signal, the first reference signal being a synchronization signal and the fourth reference signal being a demodulation reference signal;

[0176] (4) The reference signals described in this example may be a second reference signal, a third reference signal, and a fourth reference signal, where the second reference signal is a primary synchronization signal, the third reference signal is a secondary synchronization signal, and the fourth reference signal is a demodulation reference signal;

[0177] (5) The reference signal described in this example may be a fourth reference signal, which is a demodulation reference signal.

[0178] This example provides an SSB superposition design when there are multiple different reference signals, which is characterized in that multiple reference signals and first data (cell broadcast information) are multiplexed using the same time-frequency resources for transmission.

[0179] The reference signal (e.g., primary synchronization signal, secondary synchronization signal) and the first data (cell broadcast data, such as cell broadcast data carried on the PBCH channel) are superimposed and transmitted on N symbols and M carriers to form an SSB transmission scheme and SSB format for superimposed transmission of the synchronization signal (primary synchronization signal, secondary synchronization signal) and the broadcast message. The reference signal consists of a second reference signal and a third reference signal. For example, the second reference signal is the primary synchronization signal, and the third reference signal is the secondary synchronization signal. The second reference signal and the third reference signal occupy different time domain resources. For example, the second reference signal occupies N1_1 symbols, and the third reference signal occupies N1_2 symbols. The second reference signal and a part of the first data (cell broadcast data, such as cell broadcast data carried on the PBCH channel) occupy the same time-frequency domain resources, and the third reference signal and another part of the first data (cell broadcast data, such as cell broadcast data carried on the PBCH channel) occupy the same time-frequency domain resources. As shown in Figure 14.

[0180] For example, in the time domain, N1_1 and N1_2 can be one or more symbols within a time slot, such as 1 symbol, 2 symbols, 3 symbols, 4 symbols, 5 symbols, 6 symbols, 7 symbols, 8 symbols, 9 symbols, 10 symbols, 11 symbols, 12 symbols, 14 symbols, and 14 symbols. They can also be symbols within multiple time slots, all symbols within multiple time slots, or some symbols within multiple time slots. In the frequency domain, the second reference signal, the third reference signal, and the first data can use the same transmission bandwidth for different symbols, or different transmission bandwidths for different symbols. This will not be further explained.

[0181] A specific example is shown in Figure 15. Within the time-frequency resource of 2 symbols, the second reference signal (e.g., primary synchronization signal) occupies one symbol, and the third reference signal (e.g., secondary synchronization signal) occupies one symbol. The first data (cell broadcast message) is also transmitted on these two symbols, forming an SSB transmission scheme and SSB format for superimposed transmission of the primary and secondary synchronization signals and broadcast messages. The frequency domain resources for superimposed transmission of the second reference signal and the first data on the first symbol are M1_1 carriers, and the frequency domain resources for superimposed transmission of the third reference signal and the first data on the second symbol are M1_2 carriers. M1_1 can be the same as M1_2, or M1_1 and M1_2 can be different, for example, occupying different RBs.

[0182] The reference signal (e.g., primary synchronization signal, secondary synchronization signal) and the first data (cell broadcast data, such as cell broadcast data carried on the PBCH channel) are superimposed and transmitted on N symbols and M carriers to form an SSB transmission scheme and SSB format for superimposed transmission of the synchronization signal (primary synchronization signal, secondary synchronization signal) and the broadcast message. The reference signal is composed of a second reference signal and a third reference signal. For example, the second reference signal is the primary synchronization signal, and the third reference signal is the secondary synchronization signal. The second reference signal and the third reference signal occupy different frequency domain resources. For example, the second reference signal occupies M1_1 carriers, and the third reference signal occupies M1_2 carriers. The second reference signal and a part of the first data (cell broadcast data, such as cell broadcast data carried on the PBCH channel) occupy the same time-frequency domain resources, and the third reference signal and another part of the first data (cell broadcast data, such as cell broadcast data carried on the PBCH channel) occupy the same time-frequency domain resources. As shown in Figure 16.

[0183] A specific example is shown in Figure 17. Within the time-frequency resources of 1 (or 2) symbols, the second reference signal (e.g., the primary synchronization signal) occupies the first frequency domain resources (e.g., 10 RBs), and the third reference signal (e.g., the secondary synchronization signal) occupies the second frequency domain resources (e.g., another 10 RBs). The first data (cell broadcast message) is also transmitted on the reference signal symbol, forming an SSB transmission scheme and SSB format in which the primary and secondary synchronization signals and broadcast messages are superimposed on each other.

[0184] Example 3: Use case of superimposing multiple reference signals and first data

[0185] for example:

[0186] (1) The reference signal described in this example may be a second reference signal and a third reference signal, the second reference signal being a primary synchronization signal and the third reference signal being a secondary synchronization signal;

[0187] (2) The reference signals described in this example may be a first reference signal and a fourth reference signal, the first reference signal being a synchronization signal and the fourth reference signal being a demodulation reference signal;

[0188] (3) The reference signals described in this example may be the second reference signal, the third reference signal, and the fourth reference signal. The second reference signal is the primary synchronization signal, the third reference signal is the secondary synchronization signal, and the fourth reference signal is the demodulation reference signal.

[0189] X reference signals are superimposed and transmitted on time-frequency domain resources (N symbols, M carriers). Taking X equal to 2 as an example, two or more reference signals are superimposed and transmitted on the same time-domain and frequency-domain resources. For example, the first reference signal is a synchronization signal, and the fourth reference signal is a demodulation reference signal (DMRS). Or for example, the second reference signal is a primary synchronization signal, and the third reference signal is a secondary synchronization signal. For another example, X reference signals are superimposed and transmitted on the same time-domain and frequency-domain resources. The X reference signals are synchronization signals, primary synchronization signals, secondary synchronization signals, demodulation reference signals (DMRS), channel estimation-related reference signals (CSI-RS), and positioning reference signals (PRS). X is a positive integer greater than 1. The upper limit of the number of reference signals that can be superimposed and transmitted is no more than Y, for example, Y is 2, 4, 8, 16, etc. The multiple reference signals superimposed and transmitted on the same time-domain and frequency-domain resources are superimposed and transmitted with the first data (cell broadcast data, such as cell broadcast data carried on the PBCH channel), as shown in Figure 18.

[0190] For example, on N symbols and M carriers, the primary synchronization signal, the secondary synchronization signal, and the broadcast message are superimposed and transmitted to form an SSB transmission scheme and SSB format in which multiple reference signals and the first data are superimposed and transmitted.

[0191] For example, on N symbols and M carriers, the synchronization signal, broadcast message, and demodulation reference signal DMRS are superimposed and transmitted to form an SSB transmission scheme and SSB format in which multiple reference signals and the first data are superimposed and transmitted.

[0192] Furthermore, the time domain symbols N1_1 occupied by the first reference signal, the time domain symbols N1_2 occupied by the fourth reference signal, and the time domain symbols N2 occupied by the first data (cell broadcast message) may fully or partially overlap. For example, N1_1 and / or N1_2 may be less than, equal to, or greater than N2. The time domain resource locations occupied by the first reference signal and the fourth reference signal may be the same resource locations occupied by the first data (cell broadcast message), or a subset or superset thereof. The first and fourth reference signals may be replaced by the second and third reference signals.

[0193] In addition, the frequency domain carriers M1_1 occupied by the first reference signal, the frequency domain carriers M1_2 occupied by the fourth reference signal, and the frequency domain carriers M2 occupied by the first data (cell broadcast message) may fully overlap or partially overlap. For example, M1_1 and / or M1_2 may be less than, equal to, or greater than M2. The locations occupied by the first reference signal and the fourth reference signal in the frequency domain resource position may be the same resource as the frequency domain location occupied by the first data (cell broadcast message), or a subset or superset thereof. The first reference signal and the fourth reference signal may be replaced by the second reference signal and the third reference signal.

[0194] Example 4: Consider superimposing transmission of a portion of the reference signal and the first data

[0195] Based on the above examples, considering that for some weaker receivers, when the reference signal and data are completely superimposed, synchronization, measurement, channel estimation, and other tasks based on the reference signal may be problematic. This example, building on the designs of the above examples, provides a design scheme for superimposing a portion of the reference signal and the first data, reserving / allocating resources for non-superimposed transmission of the reference signal.

[0196] As shown in Figure 19, the transmission reference signal (such as a synchronization signal, a DMRS signal) and the first data (cell broadcast information) are superimposed on a subset of the resource range within the resource range occupied by the reference signal (for example, N1 symbols, M1 carrier range, including continuous resources or non-continuous resources). The subset here can be a subset in the time domain or a subset in the frequency domain, including a continuous subset and a non-continuous subset.

[0197] Within the transmission range, as shown in Figure 20:

[0198] In the time domain, there may be one or more symbols (all carriers or part of the carriers on the symbol) that only transmit reference signals, such as only transmitting synchronization signals or DMRS signals of PBCH; other positions of SSB are superimposed with transmission reference signals (such as synchronization signals, DMRS signals) and first data (cell broadcast information).

[0199] In the frequency domain, one or more carriers (all or part of the symbols on the carrier) may transmit only reference signals, such as only synchronization signals or DMRS of the PBCH; and non-superimposed transmission parts may exist in both the time domain and the frequency domain. Reference signals (such as synchronization signals, DMRS signals) and first data (cell broadcast information) are superimposed on other locations of the SSB.

[0200] Several specific examples are shown in Figure 21, for example:

[0201] (1) Within the SSB range formed by N symbols (continuous symbols or non-continuous symbols) in the time domain, for example, 4 symbols, and M carriers in the frequency domain, for example, carriers within 20 RBs: a reference signal (for example, a synchronization signal, with a frequency domain length of R carriers, for example, 127 carriers or 144 carriers) is transmitted alone on the first symbol, and the reference signal (for example, a synchronization signal) and the first data (for example, cell broadcast information) are superimposed and transmitted on several subsequent symbols, for example, the subsequent three symbols.

[0202] (2) Within the SSB range formed by N symbols (continuous symbols or non-continuous symbols) in the time domain, for example, 4 symbols, and M carriers in the frequency domain, for example, carriers within 20 RBs: there are U groups of carriers in the frequency domain, and a part of the carrier groups transmits a reference signal (for example, a synchronization signal) alone, and another part of the carrier groups transmits a reference signal (for example, a synchronization signal) and the first data (for example, cell broadcast information) in a superimposed manner.

[0203] For example, each group of carriers is a carrier within an RB, and a reference signal (e.g., a synchronization signal) is transmitted separately in the odd-group carriers, and a reference signal (e.g., a synchronization signal) and a first data (e.g., cell broadcast information) are transmitted in a superimposed manner in the even-group carriers; or a reference signal (e.g., a synchronization signal) is transmitted separately in the even-group carriers, and a reference signal (e.g., a synchronization signal) and a first data (e.g., cell broadcast information) are transmitted in a superimposed manner in the odd-group carriers.

[0204] For example, each group of carriers is U1 carriers, and a reference signal (such as a synchronization signal) is transmitted separately on a group of carriers separated by U2 groups of carriers, and the reference signal (such as a synchronization signal) and the first data (such as cell broadcast information) are superimposed and transmitted at the resource positions of the remaining groups of carriers.

[0205] Furthermore, from the perspective of resource configuration flexibility, this example provides a design at the RE level for reserving / configuring resources for non-superimposed transmission of measurement reference signals, synchronization signals, and DMRS signals within the resources where the reference signal and the first data are superimposed.

[0206] As shown in Figures 22A and 22B, within the SSB range formed by N symbols (continuous symbols or non-continuous symbols) in the time domain, for example, 4 symbols, and M carriers in the frequency domain, for example, 20 RBs, 24 RBs, or 51 RBs: some REs only transmit reference signals, for example, only synchronization signals or DMRS signals of PBCH. The part other than the above REs transmits reference signals and first data (cell broadcast information) in a superimposed manner. The RE here is a resource element, which can be 1 symbol in the time domain and 1 carrier in the frequency domain; or it can be multiple symbols in the time domain and multiple carriers in the frequency domain.

[0207] A specific example is shown in Figure 23. Within the SSB range of 4 symbols in the time domain and 20 RBs in the frequency domain, for example, a reference signal (such as a synchronization signal) is transmitted every L carriers on the first symbol and the third symbol, and the reference signal (such as a synchronization signal) and the first data (such as cell broadcast information) are superimposed and transmitted in all or part of the remaining resource positions.

[0208] Example 5: Consider superimposing the reference signal and a portion of the first data on each other

[0209] Based on the above examples, further, it is also included that: considering that the first data (such as a cell broadcast message) contains a large amount of content and occupies a large number of time-frequency resources, it is not necessary to superimpose the transmission reference signal on all resources of the first data. When the reference signal can already provide sufficient functions such as synchronization, measurement, cell discovery, channel estimation, perception, and positioning, superimposing the transmission reference signal on more resources will cause redundant transmission. For the first data, it will not result in any additional gain, but only introduce certain interference.

[0210] In response to the above problem, in this example, based on the designs of the above examples, a design scheme is provided for superimposing and transmitting a reference signal and a portion of the first data.

[0211] As shown in Figure 24, a transmission reference signal (such as a synchronization signal, a DMRS signal) and the first data (cell broadcast information) are superimposed on a subset of the resource range within the resource range occupied by the first data (broadcast message) (for example, N2 symbols, M2 carrier range, including continuous resources or non-continuous resources). The subset here can be a subset in the time domain or a subset in the frequency domain, including a continuous subset and a non-continuous subset.

[0212] Within the transmission range, as shown in Figures 25 and 26:

[0213] In the time domain, one or more symbols (all carriers or part of the carriers on the symbol) may transmit only the first data (e.g., broadcast message), for example, only the MIB is transmitted as a PBCH channel, or SIB1, other system messages, etc. Reference signals (e.g., synchronization signals, DMRS signals) and the first data (cell broadcast information) are superimposed on other positions of the SSB.

[0214] In the frequency domain, one or more carriers (all or part of the symbols on the carrier) may transmit only the first data (e.g., a broadcast message), for example, only the PBCH channel may be used to transmit the MIB, or SIB1, other system messages, etc. Reference signals (e.g., synchronization signals, DMRS signals) and the first data (cell broadcast information) may be superimposed on other locations of the SSB.

[0215] Based on the above examples, further, taking into account the flexibility of configuration and the distribution of reference signals in a wider range of time-frequency resources, this example also includes a resource subset that superimposes the reference signal and the first data at the RE level, or a resource subset that only transmits the first data (such as a broadcast message) within the SSB.

[0216] As shown in Figures 27A and 27B, within the SSB consisting of N symbols (continuous or non-continuous symbols) in the time domain, where N is a positive integer, and M carriers in the frequency domain, where M is a positive integer, some REs transmit only the first data (e.g., broadcast messages), such as transmitting the MIB only as a PBCH channel, or transmitting SIB1 and other system messages. The portion other than the aforementioned REs transmits a reference signal and the first data (cell broadcast information) in a superimposed manner. An RE is a resource element, which can be one symbol in the time domain and one carrier in the frequency domain; or it can be multiple symbols in the time domain and multiple carriers in the frequency domain.

[0217] A specific example is shown in Figure 28. Within the SSB range of N symbols in the time domain and M carriers in the frequency domain, for example, the reference signal (e.g., synchronization signal) and the first data (e.g., cell broadcast information) are superimposed and transmitted every L carriers on the first symbol and the third symbol, and only the first data (e.g., cell broadcast information) is transmitted in all or part of the remaining resource positions.

[0218] other:

[0219] The SSB in the above examples, or the superimposed transmitted reference signal and first data in the above examples, can be sent by the base station and received by the UE, as shown in Figure 29.

[0220] Regarding the type of the SSB, or the type of superimposed transmission of the reference signal and broadcast data, the network may use one or more of the following methods to notify the UE (which may be to notify the network of the type of transmission supported, or to notify the network of the type of transmission being performed, as shown in FIG30A ):

[0221] (1) Broadcast messages, such as MIB, SIB1, SIBx, (2) RRC messages, (3) MAC CE, (4) DCI messages, (5) Downlink messages randomly integrated into the process, such as MsgB, Msg2, Msg4. (4) PDCCH, (5) PDSCH, (6) AI / ML dedicated downlink channels, (7) Capability indication on the network side.

[0222] Regarding the type of SSB, or the type of superimposed transmission of reference signals and broadcast data, the UE may use one or more of the following methods to notify the network of the supported types (as shown in FIG30B ):

[0223] (1) RRC message, (2) UCI ​​message, (3) uplink message randomly integrated into the process, such as MsgA, Msg3. (4) PUCCH, (5) PUSCH, (6) AI / ML dedicated uplink channel, (7) UE capability reporting.

[0224] The communication method of the embodiment of the present application includes a design method for superimposed transmission of broadcast and synchronization signals in SSB (taking into account the influence of AIML). Through the embodiment of the present application, the superimposed transmission of reference signals (such as synchronization signals) and first data (such as cell broadcast information) can be achieved. This transmission method does not require the reference signal (such as synchronization signal) and the first data (such as cell broadcast information) to independently occupy different time-frequency resources, thereby avoiding a large amount of SSB transmission overhead. In addition, the different implementation methods given in the various examples of the embodiments of the present application fully consider the time domain synchronization requirements, frequency domain synchronization requirements, resource configuration flexibility, coexistence of multiple reference signals and other issues. The proposed method of superimposed transmission of synchronization signals and cell information on specific resources is conducive to obtaining better time domain synchronization, frequency domain synchronization, cell information acquisition and other functional effects under the constraints of limited resource overhead.
