[0001] This application relates to the field of communications, and more particularly, to a non-orthogonal transmission method, apparatus, and device for data. Background Art

[0002] Data transmission in the idle or inactive state is a special transmission mechanism that allows a terminal to send and receive UE dedicated data (i.e., small data transmission (SDT)) with the network side without entering the connected state. At present, small data transmission mainly occurs in the uplink random access message triggered by the terminal (such as message 3 (Msg3)) or the mobile-originated SDT (MO-SDT) transmitted on the Configure Grant Physical Uplink Shared Channel (CG-PUSCH), or the mobile-terminated SDT (MT-SDT) terminated by the terminal triggered in the downlink. However, with the evolution of communication technology, the performance of current small data transmission is slightly insufficient. How to further improve the performance of small data transmission is a problem that needs to be solved. Summary of the Invention

As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0051] Among them, the core network devices may include but are not limited to at least one of the following: core network nodes, core network functions, Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), Binding Support Function (BSF), Application Function (AF), Network Data Analytics Function (NWDAF), Location Management Function (LMF), etc. It should be noted that in the embodiments of this application, only the core network devices in the NR system are taken as examples for introduction, and the specific types of core network devices are not limited.

[0052] For better understanding of the embodiments of this application, the paging classification is described.

[0053] In NR, according to the message source, Paging can be classified into:

[0054] 5G Core Network (5GC) paging comes from the 5GC. When there is downlink data arriving for a UE in the Radio Resource Control (RRC)_IDLE state, the 5GC notifies the UE through a Paging message.

[0055] Radio Access Network (RAN) paging comes from the gNB. When there is downlink data arriving for a UE in the RRC_INACTIVE state, the gNB notifies the UE to start data transmission through a RAN Paging message.

[0056] The final paging message is sent by the gNB to the UE through the air interface.

[0057] To better understand the embodiments of this application, the paging channel is described.

[0058] The paging message is carried by the Paging Control Channel (PCCH) logical channel. The data block of the PCCH logical channel is carried by the Paging Channel (PCH) transport channel, and the data block of the PCH transport channel is carried by the Physical Downlink Shared Channel (PDSCH) physical channel. Since the PDSCH is a downlink shared physical channel, in addition to carrying the PCH transport channel, it can also carry the Downlink Shared Channel (DL-SCH) transport channel. Therefore, before receiving the paging message (on the PDSCH), the terminal needs to first monitor the Physical Downlink Control Channel (PDCCH) physical channel, and then determine whether the network has sent a paging message to itself in this paging cycle based on whether there is a Paging Radio Network Temporary Identity (P-RNTI) carried on the PDCCH physical channel.

[0059] Exemplarily, the Downlink Control Information (DCI) format 1_0 with a Cyclical Redundancy Check (CRC) scrambled by the P-RNTI is shown in Table 1.

[0060] Table 1

[0061]

[0062] For better understanding of the embodiments of the present application, the paging occasion (PO) and the paging frame (PF) are described.

[0063] PF and PO are two important paging-related contents. A paging frame (PF) is a radio frame that can contain one or more paging occasions (PO). A paging occasion (PO) is a subframe that may contain a paging message.

[0064] If the terminal knows the paging cycle, PF, and PO, it can know the exact time to receive the paging message. To reduce the power consumption of the UE in the RRC idle state (RRC_IDLE) or the RRC inactive state (RRC_INACTIVE), the UE uses discontinuous reception (DRX) to receive the paging message. There are several PFs within one DRX cycle, and one PF corresponds to several POs. The UE wakes up only once within one DRX cycle to detect one PO. The UE detects one paging occasion (PO) in each DRX cycle. A PO is a set of PDCCH detection occasions and may include multiple time slots (e.g., subframes or orthogonal frequency-division multiplexing (OFDM) symbols) where paging DCI can be sent.

[0065] The DRX cycle represents the cycle for the UE to detect paging, the PF represents the system frame for detecting paging, the PO represents the specific PDCCH monitoring occasions for detecting paging, and i_s represents the index of the PO corresponding to the PF. The calculation method is as follows:

[0066] PF: (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N);

[0067] i_s: i_s = floor(UE_ID / N) mod Ns;

[0068] The explanations of the parameters are as follows:

[0069] T: represents the DRX cycle;

[0070] N: the total number of PFs in T;

[0071] Ns: the number of POs corresponding to one PF;

[0072] PF_offset: PF offset;

[0073] UE_ID: 5G-S-TMSI mod 1024.

[0074] Among them, there will be a cell-level indication Tc in the system message, and RRC may also have a UE-level indication Tue. If there is no indication Tue, then T = Tc; if Tue is indicated, then T = min(Tc, Tue).

[0075] Among them, TMSI is the UE's Temporary Mobile Subscriber Identify (TMSI), which can be used to uniquely distinguish different UEs and is also used in the random access message 3 (Msg3). When the UE does not have a TMSI, the default UE_ID = 0.

[0076] The above parameters will be indicated in PCCH-config, and PCCH-config can be as follows.

[0077]

[0078]

[0079] To facilitate a better understanding of the embodiments of the present application, the paging message is described.

[0080] Currently, the format of the air interface paging message is as follows.

[0081]

[0082] In a paging message, there is a PagingRecordList carried, and this PagingRecordList carries at least 1 and at most maxNrofPageRec paging records (PagingRecord). In each PagingRecord, there is a paging identifier (ue_Identity) of the paged UE carried. That is, a paging message can indicate that at most maxNrofPageRec UEs are paged.

[0083] The paged UE has two types of identifiers. One is used to page the UE in the idle state, namely the ng-5G-S-TMSI; the other is used to page the UE in the deactivated state, namely the full I-RNTI. Among them, the UE receiving the paging message is in either the idle state or the deactivated state. In addition to sending the paging message, the DCI scheduling the paging can also carry a short message and indicate whether there are available Tracking reference signal (TRS) resources.

[0084]

[0085]

[0086] Among them, the Short Message indicator can be as shown in Table 2.

[0087] Table 2

[0088]

[0089] For better understanding of the embodiments of the present application, the random access process will be described.

[0090] The random access process can be a contention-based random access procedure or a contention-free random access process. The random access process can be a four-step random access process (also known as a Type-1 random access process) or a two-step random access process (also known as a Type-2 random access process).

[0091] In the four-step random access (4-step RACH), the UE first sends a message 1 (Msg1) to the network, which contains a preamble; after the network detects the preamble, it will send a message 2 (Msg2) or a Random Access Response (RAR) message, which contains the number of the preamble detected by the network and the uplink radio resources allocated to the UE to send a message 3 (Msg3); after the UE receives Msg2 and confirms that at least one of the preamble numbers carried in Msg2 is the same as the preamble number it sent, it sends Msg3 containing contention resolution information according to the resources indicated by the RAR; after the network receives Msg3, it will send a message 4 (Msg4) containing contention resolution information; when the UE receives Msg4 and confirms that the resolution information is the same as what it sent in Msg3, the four-step random access is completed.

[0092] The network includes uplink grant information in the RAR to indicate Msg3 Physical Uplink Shared Channel (PUSCH) scheduling information, and includes Random Access Preamble ID (RAPID), Temporary Cell Radio Network Temporary Identity (TC-RNTI), Timing Advance (TA), etc. If the network does not receive Msg3 PUSCH, it can schedule the retransmission of Msg3 PUSCH in the Physical Downlink Control Channel (PDCCH) scrambled with TC-RNTI.

[0093] For the contention-based random access procedure, different UEs randomly select preambles for transmission. In this way, different UEs may select the same preamble to send on the same time-frequency radio resources (RACH Occasion (RO) resources). This situation can be understood as the preamble collision of UEs. In this case, different UEs will receive the same RAR. Then, different UEs will perform the transmission of Msg3 PUSCH according to the scheduling information in the RAR UL grant. The network decodes the PUSCH (including contention resolution information) sent by the UE on the Msg3 PUSCH scheduling resources. Therefore, the network will include the contention resolution information received in Msg3 in Msg4. If the contention resolution information in Msg4 received by the UE matches the contention resolution information sent by the UE in Msg3 PUSCH, the UE considers the contention resolution successful. If not, the contention resolution is considered unsuccessful.

[0094] If the contention resolution is unsuccessful, the UE reselects RACH resources, performs the transmission of the Physical Random Access Channel (PRACH), and makes the next random access attempt.

[0095] In two-step random access (2-step RACH), in the first step, the UE sends Message A (MsgA) to the network side. After receiving MsgA, the network side sends Message B (MsgB) to the UE. If the UE does not receive MsgB within a certain time, the UE will increment the counter that counts the number of MsgA transmissions and re-transmit MsgA. If the counter that counts the number of MsgA transmissions reaches a certain threshold, the UE will switch from the 2-step random access procedure to the 4-step random access procedure.

[0096] MsgA includes a MsgA preamble part and a MsgA PUSCH part. The preamble part is sent on the RO used for 2-step RACH, and the PUSCH part is sent on the MsgA PUSCH resource associated with the transmission of the MsgA preamble and the RO. The MsgA PUSCH resource is a set of PUSCH resources configured for each PRACH slot, including time-frequency resources and Demodulation Reference Signal (DMRS) resources, and is associated with the PRACH resources within the PRACH slot.

[0097] To facilitate a better understanding of the embodiments of the present application, SDT is described.

[0098] The characteristics of efficient small data transmission are that for non-connected UEs (such as IDLE and INACTIVE), it is possible to avoid excessive signaling overhead caused by the resulting RRC state transition and RRC connection establishment process, and the purpose of small data transmission is achieved through a very simple signaling process.

[0099] The characteristics of the small data transmission scheme are that all the current Data Radio Bearers (DRBs) of the UE are in a suspended state rather than a released state. Therefore, before sending a ResumeRequest message, the UE can first resume the DRB and then piggyback the small data with RRC signaling. At this time, it can transmit data on the DRB just like a connected (CONNECTED) UE. Thus, state transition is avoided, and the purpose of efficient small data transmission is achieved with less signaling overhead.

[0100] Since small data transmission uses DRB transmission and the Access Stratum (AS) security has been activated, small data transmission can perform necessary security protection on data, such as data encryption and integrity protection operations. From a security perspective, since the UE may have moved to another base station in the suspended state, the security key used by the UE to resend packets at this time needs to be updated. The update method is to perform the update operation of the next key according to the parameters provided by the network side to the UE when the UE enters the suspended state for calculating the next-hop key.

[0101] The data to be transmitted in small data transmission is carried on the Dedicated Transmission Channel (DTCH) and transmitted after being multiplexed with the uplink RRC Connection Resume Request message. Similarly, if there is a replied downlink message, it can also be carried on the DTCH and multiplexed with the downlink RRC Connection Release message for transmission. The data in both the uplink and downlink is encrypted, and the encryption operation is performed using the updated next key.

[0102] Small data can also be transmitted on the Msg3 PUSCH in the 4-step RACH process, on the MsgA PUSCH in the 2-step RACH process, or on the Physical Uplink Shared Channel (PUSCH) resources scheduled by the configured grant (CG) configured in the RRC inactive state. The small data transmission in the 2-step RACH and 4-step RACH processes is called RACH based small data transmission, and the small data transmission based on the PUSCH scheduled by the configured grant is called CG based small data transmission.

[0103] To facilitate a better understanding of the embodiments of this application, the MT-EDT is described.

[0104] In the LTE system, the network side device (NW) will carry the MT-EDT trigger message through the paging message, and then the terminal (UE) initiates the EDT process. After the NW receives the request message of the UE (carrying the cause value of the MT-EDT), it concatenates the Radio Resource Control (RRC) response message with the Data Radio Bearer (DRB) data and forms a protocol data unit together, and sends it to the UE, finally realizing the reception of the downlink service.

[0105] To facilitate a better understanding of the embodiments of the present application, the rate splitting multiple access (RSMA) will be described.

[0106] The basic idea of rate splitting is to split the transmission messages for different receivers into two parts at the transmitter, which are respectively called the private part (private data stream) and the public part (public data stream). Then, the public parts of all information are combined into a whole and multiplexed through the downlink non-orthogonal multiple access technology, namely the multi-user superposition transmission (MUST) method. By designing a composite constellation, constellation points and bits are allocated to different users. Then, similar to the multi-stream transmission of traditional multi-user multiple-input multiple-output (MU-MIMO), the public data stream and multiple private data streams are transmitted within the same time-frequency resource using different precoding and demodulation reference signal (DMRS) resources; at the receiving side, in addition to decoding their own private data streams, each user also needs to decode the public data stream, and then merge the two parts of data belonging to itself into complete data. It should be noted that when decoding the public data stream, the receiving side may need to decode the information sent to other users and perform interference cancellation.

[0107] When all data is transmitted using the public data stream, data multiplexing is equivalent to the MUST technology. When all data is transmitted using the private data stream, data multiplexing is equivalent to the MU-MIMO method. Therefore, to a certain extent, RSMA is equivalent to the combination of the MUST and MU-MIMO methods.

[0108] To facilitate a better understanding of the embodiments of the present application, the downlink non-orthogonal multiple access technology will be described.

[0109] The downlink non-orthogonal multiple access (NOMA) has been studied. Its main idea is to use superposition coding and successive interference cancellation (SIC) to carry the information of multiple users on the same resource element (RE).

[0110] Among them, the superimposed coding includes: Cat 1, Cat 2, and Cat 3. Among them, Cat1 and Cat2 are to superimpose multiple sub - constellations into a composite constellation, while Cat3 is to directly divide different bits among different users based on a composite constellation.

[0111] Cat1: Different sub - constellations are superimposed with an adaptive power ratio, and the mapping between the composite constellation points and bits does not conform to the Gray mapping criterion. Taking Figure 2 as an example, this is a composite constellation formed by superimposing two sub - constellations of size 4. The constellation points of the first sub - constellation are actually the center points of the Clusters distributed in 4 quadrants in the composite constellation. For example, the 4 points in the first quadrant, although with different specific values, all represent the bit "00". And the constellation points of the second sub - constellation are the constellation points of each Cluster in the composite constellation. For example, for the first constellation point in each quadrant, the last two bits both represent the bit "10".

[0112] Cat2: Different sub - constellations are superimposed with an adaptive power ratio, and the mapping between the composite constellation points and bits conforms to the Gray mapping criterion. Taking Figure 3 as an example, this is a composite constellation formed by superimposing two sub - constellations of size 4 that conform to the Gray mapping criterion. Similar to Figure 2 except that the bit mapping rule is slightly different.

[0113] For Cat1 and Cat2, the transmitted composite constellation is formed by superimposing sub - constellations, and the variable controlling how the sub - constellations are superimposed is the power ratio. For the case of 2 users, the transmission steps at the transmitting end are as follows: The transmitting end first determines the constellation points to be transmitted according to the information bits of the first user, and then multiplies the constellation points by the power ratio where α is the power ratio of the second user; then, the transmitting end determines the constellation points to be transmitted according to the information bits of the second user, and then multiplies the constellation points by the power ratio Finally, a vector sum is performed on the two constellation points to obtain the final transmitted composite constellation point. At the receiving end, the first user only needs to determine which quadrant the constellation point is in to obtain the required bits, while the second user not only needs to determine which quadrant the constellation point is in, but also needs to determine the specific position within the quadrant. In other words, the first user only needs to demodulate 2 bits; while the second user actually needs to demodulate 4 bits and then take the last 2 bits.

[0114] Cat3: Directly divide the bits of a constellation point that conforms to the Gray mapping rule. Such as Figure 4, the entire constellation diagram conforms to the Gray mapping rule. Then it is agreed that the first 2 bits are the bits of the first user, and the last 2 bits are the bits of the second user.

[0115] It can be seen that the sub - constellations of Cat1 and Cat2 can be different, and the superimposed composite constellation may be irregular. While Cat3 first defines a regular composite constellation and then divides the bits.

[0116] For downlink NOMA, making full use of the channel conditions of different users is the key to improving the overall spectral efficiency. For example, for a user with a relatively poor channel, such as a user far from the transmitter, its resolution of constellation points is poor, and it can only distinguish constellation points with a relatively large Euclidean distance, such as constellation points in different quadrants, but cannot accurately judge constellation points within the same quadrant. On the other hand, for a user with a relatively good channel, such as a user close to the transmitter, its resolution of constellation points is good, and it can make an accurate judgment even for constellation points with a relatively small Euclidean distance. At this time, it is equivalent to being able to decode all the bits sent by the transmitter and then extract the bit information it is interested in. In practical applications, directly judging the composite constellation points to obtain all the bits and then taking partial bits is a method with a relatively high computational complexity. A method with a lower complexity is SIC: first judge the sub - constellation points with a larger Euclidean distance (that is, the constellation points sent to the far user), then remove this sub - constellation point from the received signal (vector difference), and then judge the sub - constellation points with a smaller Euclidean distance.

[0117] To facilitate a better understanding of the embodiments of the present application, the uplink non - orthogonal multiple access technology is described.

[0118] The uplink non - orthogonal multiple access technology follows two means, namely low - correlation symbol expansion and randomized mutual interference, to achieve non - orthogonal multiplexing of resources.

[0119] Low - correlation symbol expansion: Along the same idea as the modulation - based symbol expansion and code - division multiplexing of traditional Code Division Multiple Access (CDMA), but the codebook capacity of orthogonal codes is limited. For example, the number of codes in the real - number domain orthogonal codebook is the same as the length of the code, and the number of concurrent connections that can be supported is limited. Non - orthogonal codebook: Design a non - orthogonal codebook that is not completely orthogonal, contains more codes, but still maintains a relatively low correlation, supports more users to access, and at the same time maintains a relatively low mutual interference, such as a codebook that satisfies the Welch bound equality constraint. Sparse resource mapping: When mapping to physical resources, blank symbols with the same or different numbers can also be inserted to reduce the number of users superimposed on the same resource. Advantage: Explicitly reduces mutual interference, and the receiver can perform signal combination and interference cancellation (such as SIC) at the symbol level, with a relatively low complexity.

[0120] Randomized mutual interference: By means such as bit-level and symbol-level scrambling and interleaving, the correlation between user signals is reduced, and the mutual interference is whitened into noise. Advantages: Implicitly reduces mutual interference, the complexity of symbol-level scrambling is relatively low, and there is no requirement for synchronization. Challenges: The interference energy still exists (only the mutual interference is whitened), and it largely depends on the performance of the decoder to resist interference. Usually, iterative decoding is required to eliminate interference, which requires a relatively high complexity at the receiving end; interleaving requires storing long data blocks, increasing the processing delay and the complexity requirement for passive devices.

[0121] To facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments.

[0129] The paging message described in the embodiment of this application includes but is not limited to at least one of the following: Paging message, Paging control message, short message, short message control message, and data transmission control information.

[0130] It should be understood that compared with a non-orthogonal transmission mode, at least two non-orthogonal transmission modes can improve the system capacity, such as the number of concurrent users and transmission throughput.

[0131] In the embodiment of this application, the first downlink data and at least one paging message can be multiplexed and transmitted on the same time-frequency resource based on M non-orthogonal transmission modes and the signature information associated with the M non-orthogonal transmission modes, so as to improve the system capacity of the paging message and downlink data (such as the number of concurrent users and transmission throughput), and can also perform downlink data transmission more effectively. It can solve the problem that the delay of small data transmission is relatively large due to the limitation of system capacity in the scenario of small data transmission with a large number of users.

[0132] In the embodiment of this application, at least two data units obtained by splitting the first downlink data and at least one paging message can be multiplexed and transmitted on the same time-frequency resource based on M non-orthogonal transmission modes and the signature information associated with the M non-orthogonal transmission modes, so as to improve the system capacity of the paging message and downlink data (such as the number of concurrent users and transmission throughput), and can also perform downlink data transmission more effectively. It can solve the problem that the delay of small data transmission is relatively large due to the limitation of system capacity in the scenario of small data transmission with a large number of users.

[0133] In an embodiment of the present application, a data unit obtained by combining first downlink data with at least two paging messages can be multiplexed and transmitted on the same time-frequency resource based on M non-orthogonal transmission modes and signature information associated with the M non-orthogonal transmission modes, thereby improving the system capacity (such as the number of concurrent users and transmission throughput) of paging messages and downlink data, and enabling more efficient downlink data transmission. It can solve the problem of relatively large latency of small data transmission due to system capacity limitations in scenarios with a large number of users for small data transmission.

[0134] In an embodiment of the present application, the first downlink data and at least one downlink data can be multiplexed and transmitted on the same time-frequency resource based on M non-orthogonal transmission modes and signature information associated with the M non-orthogonal transmission modes, thereby improving the system capacity (such as the number of concurrent users and transmission throughput) of downlink data, and enabling more efficient downlink data transmission. It can solve the problem of relatively large latency of small data transmission due to system capacity limitations in scenarios with a large number of users for small data transmission.

[0135] In some embodiments, the first downlink data may include at least one of the following:

[0136] Downlink small data (such as MT-SDT), normal downlink data.

[0137] For example, downlink small data (such as MT-SDT) may be sent when the terminal is in the RRC idle or deactivated state, and normal downlink data may be sent when the terminal is in the RRC connected state. This embodiment can improve the data transmission capacity in the idle / inactive state, including the number of concurrent users and transmission throughput.

[0138] Exemplarily, MT-SDT may include the following: at least part of the control information, at least part of the user data.

[0139] In some implementation manners, M may also be equal to 1. For example, the first downlink data and at least one paging message are multiplexed and transmitted on the same time-frequency resource based on a specific non-orthogonal transmission mode and signature information associated with the specific non-orthogonal transmission mode, or the first downlink data and at least two data units obtained by splitting at least one paging message are multiplexed and transmitted on the same time-frequency resource based on a specific non-orthogonal transmission mode and signature information associated with the specific non-orthogonal transmission mode, or the first downlink data and a data unit obtained by combining at least two paging messages are multiplexed and transmitted on the same time-frequency resource based on a specific non-orthogonal transmission mode and signature information associated with the specific non-orthogonal transmission mode.

[0140] In the embodiments of the present application, the first uplink data and at least one uplink data can be multiplexed and transmitted on the same time-frequency resource based on N non-orthogonal transmission modes and signature information associated with the N non-orthogonal transmission modes. That is, the uplink data can be transmitted non-orthogonally based on the N non-orthogonal transmission modes and the signature information associated with the N non-orthogonal transmission modes, which can improve the transmission capacity of the uplink data (such as the number of concurrent users and transmission throughput), and can also perform uplink data transmission more effectively. It can solve the problem that the delay of small data transmission is relatively large due to the limitation of system capacity in the scenario where a large number of users perform small data transmission.

[0141] In some embodiments, the first uplink data may include at least one of the following:

[0142] Uplink small data (such as MO-SDT), normal uplink data.

[0143] For example, the uplink small data (such as MO-SDT) may be sent by the terminal when it is in the RRC idle or deactivated state, and the normal uplink data may be sent by the terminal when it is in the RRC connected state. This embodiment can improve the data transmission capacity in the idle / inactive state, including the number of concurrent users and transmission throughput.

[0144] In the embodiments of the present application, the signature information (Signature) associated with the non-orthogonal transmission mode i can decode the data corresponding to the non-orthogonal transmission mode i.

[0145] In some embodiments, the M non-orthogonal transmission modes include but are not limited to at least one of the following: based on the spreading mode, based on the interleaving mode, based on the bit scrambling mode, based on the symbol interleaving mode, based on the symbol scrambling mode, based on the superposition symbol transmission mode, based on the rate splitting mode, based on the space division mode.

[0146] Exemplarily, the spreading-based mode may be, for example, Multi-User Sharing Access (MUSA), Pattern Division Multiple Access (PDMA), Sparse Code Multiple Access (SCMA), etc.

[0147] Specifically, for example, based on the symbol extension method which is similar to CDMA, but the spreading sequences are non-orthogonal. Taking two users as an example, for the transmitter, each symbol of the first symbol stream from the first data stream (such as the first TB) and each symbol of the second symbol stream from the second data stream (such as the second TB) are multiplied by the first spreading sequence and the second spreading sequence respectively, and then superimposed on the same multiple REs (the number of REs is the same as the length of the spreading sequence) for transmission.

[0148] Exemplarily, the method based on bit interleaving can be, for example, Interleave Division Multiple Access (IDMA), Interleave-Grid Multiple Access (IGMA), etc.

[0149] Specifically, for example, for the method based on bit interleaving, taking two users as an example, for the transmitter, the first bit stream from the first data stream (such as the first TB) and the second bit stream from the second data stream (such as the second TB) are interleaved by the first bit interleaver and the second bit interleaver respectively, and then after modulation, they are superimposed on the same REs for transmission.

[0150] Exemplarily, the method based on bit scrambling can be, for example, Low Code Rate Spreading (LCRS).

[0151] Specifically, for example, for the method based on bit scrambling, taking two users as an example, for the transmitter, the first bit stream from the first data stream (such as the first TB) and the second bit stream from the second data stream (such as the second TB) are scrambled by the first bit scrambler (or scrambling sequence) and the second bit scrambler (or scrambling sequence) respectively, and then after modulation, they are superimposed on the same REs for transmission.

[0152] Specifically, for example, for the method based on symbol interleaving, taking two users as an example, for the transmitter, the first symbol stream from the first data stream (such as the first TB) and the second symbol stream from the second data stream (such as the second TB) are interleaved by the first symbol interleaver and the second symbol interleaver respectively, and then they are superimposed on the same REs for transmission.

[0153] Specifically, for example, for the method based on symbol scrambling, taking two users as an example, for the transmitter, the first symbol stream from the first data stream (such as the first TB) and the second symbol stream from the second data stream (such as the second TB) are scrambled by the first symbol scrambler (or scrambling sequence) and the second symbol scrambler (or scrambling sequence) respectively, and then after modulation, they are superimposed on the same REs for transmission.

[0154] Exemplarily, the superposition symbol transmission mode can be MUST or the like.

[0155] Specifically, for the superposition symbol transmission mode, taking two users as an example, for the transmitting end, each symbol of the first symbol stream from the first data stream (such as the first TB) and each symbol of the second symbol stream from the second data stream (such as the second TB) are respectively multiplied by the first power control factor and the second power control factor, and then superimposed on the same RE for transmission.

[0156] Exemplarily, the rate splitting mode can be RSMA or the like.

[0157] Exemplarily, the spatial division mode can be MU-MIMO, RSMA or the like.

[0158] In some embodiments, the signature information associated with M non-orthogonal transmission modes includes at least one of the following:

[0159] Symbol extension sequence, bit interleaver or bit interleaving method, bit scrambling sequence or method for generating bit scrambling sequence, symbol interleaver or symbol interleaving method, symbol scrambling sequence or method for generating symbol scrambling sequence, mapping method from bit to symbol, mapping method from bit sequence to symbol sequence, RSMA common stream or layer index of MUST or power allocation factor of MUST or modulation mode of MUST, RSMA private stream or precoding or beam of MU-MIMO or DMRS port of MU-MIMO.

[0160] Exemplarily, the signature information associated with the symbol extension mode can be the symbol extension sequence (SpreadingSequence), the signature information associated with the bit interleaving mode can be the bit interleaver or bit interleaving method, the signature information associated with the bit scrambling mode can be the bit scrambling sequence or method for generating bit scrambling sequence, the signature information associated with the symbol interleaving mode can be the symbol interleaver or symbol interleaving method, the signature information associated with the symbol scrambling mode can be the symbol scrambling sequence or method for generating symbol scrambling sequence, the signature information associated with the superposition symbol transmission mode can be the mapping method from bit to symbol or mapping method from bit sequence to symbol sequence, the signature information associated with the rate splitting mode can be the RSMA common stream or layer index of MUST or power allocation factor of MUST or modulation mode of MUST, and the signature information associated with the spatial division mode can be the RSMA private stream or precoding or beam of MU-MIMO or DMRS port of MU-MIMO.

[0161] In some embodiments, the N non-orthogonal transmission modes include, but are not limited to, at least one of the following: symbol extension mode, bit interleaving mode, bit scrambling mode, symbol interleaving mode, symbol scrambling mode, superimposed symbol transmission mode, rate splitting mode, and spatial division mode.

[0162] In some embodiments, the signature information associated with the N non-orthogonal transmission modes includes at least one of the following:

[0163] Symbol extension sequence, bit interleaver or bit interleaving method, bit scrambling sequence or method for generating bit scrambling sequence, symbol interleaver or symbol interleaving method, symbol scrambling sequence or method for generating symbol scrambling sequence, bit-to-symbol mapping method, bit sequence-to-symbol sequence mapping method, RSMA common stream or layer index of MUST or power allocation factor of MUST or modulation mode of MUST, RSMA private stream or precoding of MU-MIMO or beam or DMRS port of MU-MIMO.

[0164] It should be noted that the relevant descriptions of the N non-orthogonal transmission modes can refer to the above-mentioned M non-orthogonal transmission modes. For the sake of brevity, they will not be elaborated here.

[0165] In some embodiments, the at least two data units are obtained by splitting the at least one paging message based on at least one of the following levels:

[0166] Paged UE (PagingUE), Paged UE group (PagingUEgroup), Paging record (PagingRecord).

[0167] Exemplarily, a paging message can be split into different data units based on levels such as the paged UE (PagingUE), the paged UE group (PagingUEgroup), and the paging record (PagingRecord).

[0168] In some embodiments, the at least one downlink data is a repeated transmission of the first downlink data, or the at least one downlink data is the downlink data of other terminals, or the first downlink data and the at least one downlink data are different parts of specific downlink data.

[0169] Specifically, in order to improve transmission reliability, the method of repeated (Repetition) transmission can be adopted when sending downlink data, and different Repetition versions / parts can adopt different non-orthogonal transmission modes and Signatures. For example, the reliability of downlink data transmission can be improved by repeating the transmission of downlink data.

[0170] Exemplarily, the repeated transmission of the downlink data described in this embodiment can be a repeated transmission for one terminal or a repeated transmission for multiple terminals, and this embodiment does not limit this.

[0171] In some embodiments, when the at least one downlink data is a repeated transmission of the first downlink data, different repeated transmission versions correspond to the same set of non-orthogonal transmission methods and different signature information, or different repeated transmission groups correspond to the same set of non-orthogonal transmission methods and different signature information, or different repeated transmission versions correspond to different sets of non-orthogonal transmission methods, or different repeated transmission groups correspond to different sets of non-orthogonal transmission methods, or different repeated transmission versions correspond to the same set of non-orthogonal transmission methods and the same signature information, or different repeated transmission groups correspond to the same set of non-orthogonal transmission methods and the same signature information.

[0172] It should be noted that different repeated transmission versions corresponding to the same set of non-orthogonal transmission methods and the same signature information, or different repeated transmission groups corresponding to the same set of non-orthogonal transmission methods and the same signature information can reduce the implementation complexity.

[0173] In the embodiments of the present application, the content transmitted by different repeated transmission versions can be the same or slightly different. For example, some parameters can be adjusted, and this embodiment does not limit this.

[0174] The different repeated transmission versions described in the embodiments of the present application can also be referred to as different times of repeated transmission, and this embodiment does not limit this.

[0175] Exemplarily, when the at least one downlink data is a repeated transmission of the first downlink data, different repeated transmission versions or repeated transmission groups can adopt the same set of non-orthogonal transmission methods and different Signatures.

[0176] For example, assume a case of two downlink transmissions for two UEs. In the first transmission, a non-orthogonal transmission mode and a signature set {non-orthogonal transmission mode 1, corresponding signature parameter or parameter ID 1; non-orthogonal transmission mode 2, corresponding signature parameter or parameter ID 2, …} can be adopted; in the second transmission, a non-orthogonal transmission mode and a signature set {non-orthogonal transmission mode 1, corresponding signature parameter or parameter ID 1'; non-orthogonal transmission mode 2, corresponding signature parameter or parameter ID 2', …} can be adopted. More specifically, for the non-orthogonal transmission mode based on symbol superposition, in the first transmission, the data of UE 1 can be placed in the layer with a lower index, and the data of UE 2 can be placed in the layer with a higher index; while in the second transmission, the data of UE 1 can be placed in the layer with a higher index, and the data of UE 2 can be placed in the layer with a lower index. And so on for other cases. For example, when using the method of symbol extension, the sequences adopted in the first transmission and the second transmission can be different, etc.

[0177] Exemplarily, in the case where at least one downlink data is a repeated transmission of the first downlink data, different repeated transmission versions or repeated transmission groups can adopt different non-orthogonal transmission mode sets. Since the non-orthogonal transmission modes are different, the meanings of the signatures are different. If the signature parameters are configured in the form of indices (IDs), the signature indices can be the same or different.

[0178] For example, only different non-orthogonal transmission modes are indicated, but the signature index remains unchanged. For instance, assume a case of two downlink transmissions for two UEs. In the first transmission, a non-orthogonal transmission mode and a signature set {non-orthogonal transmission mode 1, corresponding signature parameter ID 1; non-orthogonal transmission mode 2, corresponding signature parameter ID 2, …} can be adopted; in the second transmission, a non-orthogonal transmission mode and a signature set {non-orthogonal transmission mode 1'; non-orthogonal transmission mode 2'; …} can be adopted.

[0179] For another example, both the non-orthogonal transmission mode and the signature index can vary. For instance, assuming the case of two downlink transmissions for two UEs, in the first transmission, a non-orthogonal transmission mode and a signature set {non-orthogonal transmission mode 1, corresponding signature parameter id 1; non-orthogonal transmission mode 2, corresponding signature parameter id 2, ……} can be adopted; in the second transmission, a non-orthogonal transmission mode and a signature set {non-orthogonal transmission mode 1’, corresponding signature parameter id 1’; non-orthogonal transmission mode 2’, corresponding signature parameter id 2’, ……} can be adopted.

[0180] For yet another example, the original value of the signature parameter is indicated. For instance, assuming the case of two downlink transmissions for two UEs, in the first transmission, a non-orthogonal transmission mode and a signature set {non-orthogonal transmission mode 1, corresponding signature parameter 1; non-orthogonal transmission mode 2, corresponding signature parameter 2, ……} can be adopted; in the second transmission, a non-orthogonal transmission mode and a signature set {non-orthogonal transmission mode 1’, corresponding signature parameter 1’; non-orthogonal transmission mode 2’, corresponding signature parameter 2’, ……} can be adopted.

[0181] In some embodiments, the terminal is configured to allow symbol-level or bit-level merging of data with different repeated transmission versions, or, the terminal is configured to allow symbol-level or bit-level merging of data with different repeated transmission groups, or, the terminal is configured to allow symbol-level or bit-level merging of data with different repeated transmission versions within the same repeated transmission group.

[0182] Exemplarily, the network-side device sends configuration information to the terminal;

[0183] wherein, the configuration information is used to configure the terminal to allow symbol-level or bit-level merging of data with different repeated transmission versions, or, the configuration information is used to configure the terminal to allow symbol-level or bit-level merging of data with different repeated transmission groups, or, the configuration information is used to configure the terminal to allow symbol-level or bit-level merging of data with different repeated transmission versions within the same repeated transmission group.

[0184] Specifically, for example, in the case where the repeated transmission of downlink data described in this embodiment is a repeated transmission for multiple terminals, some or all of the multiple terminals may be configured to allow symbol-level or bit-level merging of data of different repeated transmission versions, or some or all of the multiple terminals may be configured to allow symbol-level or bit-level merging of data of different repeated transmission groups, or some or all of the multiple terminals may be configured to allow symbol-level or bit-level merging of data of different repeated transmission versions within the same repeated transmission group.

[0185] Exemplarily, a terminal (UE) or a network-side device (such as a TRP) may perform symbol-level or bit-level merging on data of different Repetitions or repetition groups or different repetitions of the same repetition group.

[0186] For example, if different Repetitions all adopt symbol-level non-orthogonal transmission, after the received signal undergoes corresponding receiving processing (such as symbol expansion at the transmitting end and symbol de-expansion at the receiving end; symbol scrambling at the transmitting end and symbol descrambling at the receiving end, etc.), the symbols of multiple Repetitions can be merged into one symbol, and then symbol decision is performed.

[0187] For example, if different Repetitions involve bit-level non-orthogonal transmission, then merging can be performed at the bit level. For example, the maximum log-likelihood ratios (Log-Likelihood Ratio, LLR) of different Repetitions of the bits to be decided are merged into one LLR after certain operations, and then bit decision is performed.

[0188] In some embodiments, in the case where the at least one downlink data is the downlink data of other terminals, the signature information (such as signature ID) associated with the M non-orthogonal transmission methods is associated with the identifier (UE ID) of the paged terminal, or the signature information (such as signature ID) associated with the M non-orthogonal transmission methods is associated with the order of the paged terminal in the paging record list, or the signature information (such as signature ID) associated with the M non-orthogonal transmission methods is configured by a paging-related channel (such as PDCCH or PDSCH).

[0189] In some embodiments, when the at least one downlink data is the downlink data of other terminals, the M non-orthogonal transmission modes and the signature information (such as signature ID) associated with the M non-orthogonal transmission modes are associated with the identifier of the paged terminal, or the M non-orthogonal transmission modes and the signature information (such as signature ID) associated with the M non-orthogonal transmission modes are associated with the order of the paged terminal in the paging record list, or the M non-orthogonal transmission modes and the signature information (such as signature ID) associated with the M non-orthogonal transmission modes are configured by a paging-related channel (such as PDCCH or PDSCH).

[0190] In some embodiments, the at least one uplink data is a repeated transmission of the first uplink data, or the at least one uplink data is the uplink data of other terminals, or the first uplink data and the at least one uplink data are different parts of specific uplink data.

[0191] Specifically, in order to improve transmission reliability, the method of repeated (Repetition) transmission can be adopted when sending uplink data, and different Repetition versions / parts can adopt different non-orthogonal transmission modes and Signatures. For example, the reliability of uplink data transmission can be improved by repeating the transmission of uplink data.

[0192] Exemplarily, the repeated transmission of the uplink data described in this embodiment can be the repeated transmission of one terminal or the repeated transmission of multiple terminals, and this embodiment does not limit this.

[0193] In some embodiments, when the at least one uplink data is a repeated transmission of the first uplink data, different repeated transmission versions correspond to the same set of non-orthogonal transmission modes and different signature information, or different repeated transmission groups correspond to the same set of non-orthogonal transmission modes and different signature information, or different repeated transmission versions correspond to different sets of non-orthogonal transmission modes, or different repeated transmission groups correspond to different sets of non-orthogonal transmission modes, or different repeated transmission versions correspond to the same set of non-orthogonal transmission modes and the same signature information, or different repeated transmission groups correspond to the same set of non-orthogonal transmission modes and the same signature information.

[0194] It should be noted that different repeated transmission versions corresponding to the same set of non-orthogonal transmission modes and the same signature information, or different repeated transmission groups corresponding to the same set of non-orthogonal transmission modes and the same signature information can reduce the implementation complexity.

[0195] Exemplarily, in the case where at least one uplink data is a repeated transmission of first uplink data, different repeated transmission versions or repeated transmission groups may adopt the same set of non-orthogonal transmission methods and different Signatures.

[0196] For example, assume the case of 2 UEs with 2 uplink transmissions. In the first transmission, a non-orthogonal transmission method and a signature set {non-orthogonal transmission method 1, corresponding signature parameter or parameter id 1; non-orthogonal transmission method 2, corresponding signature parameter or parameter id 2,...} may be adopted; in the second transmission, a non-orthogonal transmission method and a signature set {non-orthogonal transmission method 1, corresponding signature parameter or parameter id 1'; non-orthogonal transmission method 2, corresponding signature parameter or parameter id 2',...} may be adopted. More specifically, for the non-orthogonal transmission method based on symbol superposition, in the first transmission, the data of UE 1 may be placed in the layer with a lower index, and the data of UE 2 may be placed in the layer with a higher index; while in the second transmission, the data of UE 1 may be placed in the layer with a higher index, and the data of UE 2 may be placed in the layer with a lower index. And so on for other cases. For example, when using the method of symbol extension, the sequences adopted in the first transmission and the second transmission may be different, etc.

[0197] Exemplarily, in the case where at least one uplink data is a repeated transmission of first uplink data, different repeated transmission versions or repeated transmission groups may adopt different sets of non-orthogonal transmission methods. Since the non-orthogonal transmission methods are different and the meanings of the Signatures are different, if the signature parameters are configured in the form of indexes (ids), the signature indexes may be the same or different.

[0198] For example, only different non-orthogonal transmission methods are indicated, but the signature indexes remain unchanged. For instance, assume the case of 2 UEs with 2 uplink transmissions. In the first transmission, a non-orthogonal transmission method and a signature set {non-orthogonal transmission method 1, corresponding signature parameter id 1; non-orthogonal transmission method 2, corresponding signature parameter id2,...} may be adopted; in the second transmission, a non-orthogonal transmission method and a signature set {non-orthogonal transmission method 1'; non-orthogonal transmission method 2';...} may be adopted.

[0199] For another example, both the non-orthogonal transmission mode and the signature index can vary. For instance, assuming the case of two UEs with two uplink transmissions, in the first transmission, a non-orthogonal transmission mode and a signature set {non-orthogonal transmission mode 1, corresponding signature parameter id 1; non-orthogonal transmission mode 2, corresponding signature parameter id 2, …} can be adopted; in the second transmission, a non-orthogonal transmission mode and a signature set {non-orthogonal transmission mode 1’, corresponding signature parameter id 1’; non-orthogonal transmission mode 2’, corresponding signature parameter id 2’, …} can be adopted.

[0200] For yet another example, the original values of the signature parameters are indicated. For instance, assuming the case of two UEs with two uplink transmissions, in the first transmission, a non-orthogonal transmission mode and a signature set {non-orthogonal transmission mode 1, corresponding signature parameter 1; non-orthogonal transmission mode 2, corresponding signature parameter 2, …} can be adopted; in the second transmission, a non-orthogonal transmission mode and a signature set {non-orthogonal transmission mode 1’, corresponding signature parameter 1’; non-orthogonal transmission mode 2’, corresponding signature parameter 2’, …} can be adopted.

[0201] In some embodiments, when the at least one uplink data is the uplink data of other terminals, the signature information (such as signature ID) associated with the N non-orthogonal transmission modes is associated with the identifier of the paged terminal, or the signature information (such as signature ID) associated with the N non-orthogonal transmission modes is associated with the order of the paged terminal in the paging record list, or the signature information (such as signature ID) associated with the N non-orthogonal transmission modes is configured by a paging-related channel (such as PDCCH or PDSCH).

[0202] In some embodiments, the N non-orthogonal transmission modes and the signature information (such as signature ID) associated with the N non-orthogonal transmission modes are associated with the identifier of the paged terminal, or the N non-orthogonal transmission modes and the signature information (such as signature ID) associated with the N non-orthogonal transmission modes are associated with the order of the paged terminal in the paging record list, or the N non-orthogonal transmission modes and the signature information (such as signature ID) associated with the N non-orthogonal transmission modes are configured by a paging-related channel (such as PDCCH or PDSCH).

[0203] In some embodiments, the M non-orthogonal transmission modes and the signature information associated with the M non-orthogonal transmission modes are determined based on at least one of the following: the priority information of the terminal, the priority information of the data stream, the reliability requirement of the terminal, the reliability requirement of the data stream, the distance between the terminal and the network-side device (such as a base station or a TRP), the relevant information of the uplink channel from the terminal to the network-side device, and the relevant information of the downlink channel from the network-side device to the terminal.

[0204] In some embodiments, the N non-orthogonal transmission modes and the signature information associated with the N non-orthogonal transmission modes are determined based on at least one of the following: the priority information of the terminal, the priority information of the data stream, the reliability requirement of the terminal, the reliability requirement of the data stream, the distance between the terminal and the network-side device, the relevant information of the uplink channel from the terminal to the network-side device, and the relevant information of the downlink channel from the network-side device to the terminal.

[0205] Exemplarily, in the case of knowing the priority information of the terminal, the superposition symbol transmission mode can be adopted, and a Layer with a lower index can be configured for the high-priority terminal (the Layer with a lower index is defined as: the Layer that is demodulated first by the receiving end); the rate splitting mode can also be adopted, and the high-priority terminal can be configured to use the common stream for transmission. Further, a Layer with a lower index in the common stream can be configured for the high-priority terminal; the symbol extension sequence mode can also be adopted, and a sequence with a smaller cross-correlation can be allocated to the high-priority terminal. For the above methods, a larger power allocation factor (equivalent to allocating more power) can be configured for the high-priority terminal during downlink transmission.

[0206] Exemplarily, in the case of knowing the priority information of the data stream, the superposition symbol transmission mode can be adopted, and a Layer with a lower index can be configured for the high-priority data stream (the Layer with a lower index is defined as: the Layer that is demodulated first by the receiving end); the rate splitting mode can also be adopted, and the high-priority data stream can be configured to use the common stream for transmission. Further, a Layer with a lower index in the common stream can be configured for the high-priority data stream; the symbol extension sequence mode can also be adopted, and a sequence with a smaller cross-correlation can be allocated to the high-priority data stream. For the above methods, a larger power allocation factor (equivalent to allocating more power) can be configured for the high-priority data stream during downlink transmission.

[0207] Exemplarily, when the reliability requirements of the terminal are known, the superposition symbol transmission mode can be adopted, and a Layer with a lower index can be configured for the terminal with high reliability requirements (the Layer with a lower index is defined as the Layer that is demodulated first by the receiving end); the rate splitting mode can also be adopted, and the common stream transmission can be configured for the terminal with high reliability requirements. Further, a Layer with a lower index in the common stream can be configured for the terminal with high reliability requirements; the symbol extension sequence mode can also be adopted, and a sequence with a smaller cross-correlation can be allocated for the terminal with high reliability requirements. For the above methods, a larger power allocation factor (equivalent to allocating more power) is configured for the terminal with high reliability requirements during downlink transmission.

[0208] Exemplarily, when the reliability requirements of the data stream are known, the superposition symbol transmission mode can be adopted, and a Layer with a lower index can be configured for the data stream with high reliability requirements (the Layer with a lower index is defined as the Layer that is demodulated first by the receiving end); the rate splitting mode can also be adopted, and the common stream transmission can be configured for the data stream with high reliability requirements. Further, a Layer with a lower index in the common stream can be configured for the data stream with high reliability requirements; the symbol extension sequence mode can also be adopted, and a sequence with a smaller cross-correlation can be allocated for the data stream with high reliability requirements. For the above methods, a larger power allocation factor (equivalent to allocating more power) is configured for the data stream with high reliability requirements during downlink transmission.

[0209] Exemplarily, when the distance between the UE and the TRP is known, the method based on superposition symbol transmission can be adopted, and a Layer with a lower index can be configured for the farther UE (the Layer that is demodulated first by the receiving end); the method based on rate splitting can also be adopted, and the common stream can be configured for the UE with high priority. Further, a Layer with a lower index in the common stream can be configured for the UE with high priority.

[0210] Exemplarily, when the prior information about the downlink channel from the TRP to the UE or the uplink channel from the UE to the TRP is known, such as when sounding reference signals (SRS) or channel state information reference signals (CSI-RS) configured as Inactive / idle are available, private streams or precoding or beams or DMRS ports for MU-MIMO can be configured for the UE.

[0211] In some embodiments, when the network does not have prior information of the UE, non-orthogonal transmission methods and Signatures independent of UE characteristics can be adopted, such as randomly configuring symbol extension sequences, randomly configuring bit interleaving or interleaving methods, randomly configuring bit scrambling sequences or sequence generation methods, randomly configuring symbol interleaving or interleaving methods, randomly configuring symbol scrambling sequences or sequence generation methods, randomly configuring symbol superposition transmission / RSMA common stream Layer or power allocation factor, randomly configuring RSMA private stream or MU-MIMO precoding or beam, DMRS port. The above methods can be used alone or in combination.

[0212] In some embodiments, the M non-orthogonal transmission methods and the signature information associated with the M non-orthogonal transmission methods are determined from a preset non-orthogonal transmission method and the associated signature information based on at least one of the following: RRC state, size of downlink data to be transmitted, number of paged terminals, whether the terminal supports beam management in the idle state or deactivated state, whether the terminal supports location management or positioning in the idle state or deactivated state.

[0213] In some embodiments, the N non-orthogonal transmission methods and the signature information associated with the N non-orthogonal transmission methods are determined from a preset non-orthogonal transmission method and the associated signature information based on at least one of the following: RRC state, size of downlink data to be transmitted, number of paged terminals, whether the terminal supports beam management in the idle state or deactivated state, whether the terminal supports location management or positioning in the idle state or deactivated state.

[0214] Exemplarily, the non-orthogonal transmission method can be implicitly configured, or, the non-orthogonal transmission method and the associated signature information can be implicitly configured.

[0215] For example, the non-orthogonal transmission method is determined according to the RRC state of the UE, or, the non-orthogonal transmission method and the associated signature information are determined according to the RRC state of the UE. For instance, the Inactive state corresponds to a non-orthogonal transmission method and a signature set {non-orthogonal transmission method 1, corresponding signature parameter 1; non-orthogonal transmission method 2, corresponding signature parameter 2,...}. The Idle state corresponds to a non-orthogonal transmission method and a signature set {non-orthogonal transmission method 1', corresponding signature parameter 1'; non-orthogonal transmission method 2', corresponding signature parameter 2',...}.

[0216] For another example, determine the non-orthogonal transmission mode according to the size of the data to be transmitted, or determine the non-orthogonal transmission mode and the associated signature information according to the size of the data to be transmitted. For example, preset matching conditions, and when the size of the payload of the SDT, physical channel, logical channel, paging message or transport block (TB) meets a certain range, use the corresponding non-orthogonal transmission mode and signature set.

[0217] For another example, determine the non-orthogonal transmission mode according to the number of paged terminals, or determine the non-orthogonal transmission mode and the associated signature information according to the number of paged terminals. For example, preset matching conditions, and when the number of UEs in the Paging message or the number of UEs scheduled for SDT by Paging meets a certain range, use the corresponding non-orthogonal transmission mode and signature set.

[0218] For another example, determine the non-orthogonal transmission mode according to whether the UE supports beam management in idle / inactive, or determine the non-orthogonal transmission mode and the associated signature information according to whether the UE supports beam management in idle / inactive.

[0219] Optionally, beam management includes at least one of the following:

[0220] Transmit an uplink reference signal, such as SRS for uplink beam training;

[0221] Receive a downlink reference signal, such as CSI-RS for downlink beam training, and the corresponding measurement report;

[0222] Preset matching conditions, such as using the corresponding non-orthogonal transmission mode and signature set when beam management is not supported;

[0223] Remove the unusable non-orthogonal transmission modes from the configured non-orthogonal transmission modes and signature set, such as removing the private stream or MU-MIMO transmission based on non-codebook RSMA;

[0224] Preset matching conditions, and use the corresponding non-orthogonal transmission mode and signature set when beam management is supported.

[0225] For another example, determine the non-orthogonal transmission mode according to whether the UE can perform location management / location in idle / inactive, or determine the non-orthogonal transmission mode and the associated signature information according to whether the UE can perform location management / location in idle / inactive.

[0226] Optionally, location management includes but is not limited to only one of the following:

[0227] Measure the distance between the measurement terminal and one or more TRPs;

[0228] Measure the Global Navigation Satellite System (GNSS) signals to obtain coordinates;

[0229] Estimate the terminal location based on the cell identifier.

[0230] For another example, preset matching conditions. For instance, when location management or positioning is not supported, use corresponding non-orthogonal transmission methods and signature sets; or remove unusable non-orthogonal transmission methods from the configured non-orthogonal transmission methods and signature sets, such as based on symbol superposition transmission methods. Or, preset matching conditions. When location management or positioning is supported, use corresponding non-orthogonal transmission methods and signature sets.

[0231] In some embodiments, the non-orthogonal transmission method 200 of the data further includes:

[0232] The terminal receives the first information;

[0233] Wherein, the first information is used to configure or indicate at least one of the following: some or all of the M non-orthogonal transmission methods, the signature information associated with some or all of the M non-orthogonal transmission methods, some or all of the N non-orthogonal transmission methods, the signature information associated with some or all of the N non-orthogonal transmission methods.

[0234] In this embodiment, the terminal can determine some or all of the M non-orthogonal transmission methods based on the first information, or the terminal can determine the signature information associated with some or all of the M non-orthogonal transmission methods based on the first information, or the terminal can determine some or all of the N non-orthogonal transmission methods based on the first information, or the terminal can determine the signature information associated with some or all of the N non-orthogonal transmission methods based on the first information. Thus, the terminal can know how to perform MT-SDT or MO-SDT.

[0235] In some embodiments, the first information is carried by at least one of the following:

[0236] Paging message, control channel for scheduling paging (such as PDCCH), data channel carrying paging (such as PDSCH), RRC release message, system message, Synchronization Signal Block (SSB).

[0237] The SSB described in the embodiments of the present application can be used interchangeably with the Synchronization Signal / Physical Broadcast Signal Block (SS / PBCH block), and can also be called any information block or resource block that includes at least one of synchronization signals, broadcast signals, broadcast channels, other system messages, and downlink broadcast channels.

[0238] In some embodiments, when the first information is carried by a control channel for scheduling paging, at least two control channels for scheduling paging (such as PDCCH) are used to schedule a data channel for carrying paging (such as PDSCH);

[0239] Among them, the data channel (such as PDSCH) scheduled by the at least two control channels for scheduling paging (such as PDCCH) carries downlink data multiplexed on the same time-frequency resource based on the M non-orthogonal transmission methods and the signature information associated with the M non-orthogonal transmission methods, or the data channel (such as PDSCH) scheduled by the at least two control channels for scheduling paging (such as PDCCH) does not carry the first downlink data.

[0240] Exemplarily, 1 PDSCH can be scheduled by at least two PDCCHs. The PDSCH can carry multiple TBs or multiple data streams of 1 TB. These TBs or data streams are multiplexed on the same time-frequency resource through non-orthogonal transmission methods, and each TB or each data stream is scheduled by 1 PDCCH. For example, for the method based on superimposed symbols transmission, the TRP can carry multiple MT-SDT TBs for a UE on different Layers respectively, and inform the UE how to resolve the signals of the corresponding Layer through their respective PDCCHs. For example, the PDSCH can be just the Paging PDSCH that multiplexes multiple UE Paging messages and does not carry MT-SDT.

[0241] In some embodiments, the first information is configuration information at the per Paging UE granularity, or the first information is configuration information at the per Paging Record granularity, or the first information is configuration information at the per Paging Record List granularity, or the first information is configuration information at the per Paging message granularity.

[0242] In some embodiments, when the first information is the configuration information of the per Paging UE granularity, a new configuration field is introduced in the Paging UE ID to indicate the non-orthogonal transmission mode of the SDT (such as MT-SDT or MO-SDT) and the corresponding Signature. Specifically, the per Paging UE can be configured with the smallest granularity, and a unique non-orthogonal transmission mode and the corresponding Signature set are assigned to each UE.

[0243] In some embodiments, when the first information is the configuration information of the per Paging Record granularity, the first information is a new field in the paging record, and the first information includes a first container or a first parameter group;

[0244] Wherein, the first container includes the non-orthogonal transmission modes configured for at least two terminals respectively and the signature information associated therewith. The at least two terminals belong to the terminals corresponding to the paging record, and the at least two terminals include the terminal;

[0245] Wherein, the first parameter group includes a set of non-orthogonal transmission modes and the signature information associated therewith that are effective for all terminals corresponding to the paging record.

[0246] Exemplarily, a new configuration field is introduced in the Paging Record to indicate the non-orthogonal transmission mode of SDT (such as MT-SDT or MO-SDT) and the corresponding Signature set for all UEs in the Record.

[0247] Specifically, for example, the new configuration field (i.e., the first information) in the Paging Record can be a container (i.e., the first container) containing a set of parameters for multiple UE configurations, or a set of parameter configurations effective for all UEs (i.e., the first parameter group). For the container of a set of parameters (i.e., the first container), it is still configured per Paging UE, but is configured in the Paging Record in the form of a container. For a set of parameter configurations effective for all UEs (i.e., the first parameter group), a group of UEs will reuse the same parameters, but some methods are needed to obtain different parameters per UE according to a set of the same parameters, that is, the non-orthogonal transmission modes and Signatures actually adopted by the UEs are not completely the same, according to mapping or randomization methods.

[0248] Optionally, when the first information includes the first parameter group, each terminal determines the corresponding non-orthogonal transmission mode and the signature information associated therewith based on at least one of the following:

[0249] Partial or all of the UE IDs, paging occasions (POs), system frame numbers (SFNs), and preset parameters (which can also be preset operation methods).

[0250] Exemplarily, the terminal may obtain an index corresponding to a set of non-orthogonal transmission modes and the corresponding signature indexes by mapping (or through a given operation method) based on the complete UE ID (such as Temporary Mobile Subscriber Identity (TMSI), Globally Unique Temporary Identity (GUTI)) or partial UE ID. Alternatively, the terminal may map (or through a given operation method) the complete UE ID (such as TMSI, GUTI) or partial UE ID to two indexes, corresponding to a non-orthogonal transmission mode and a signature respectively.

[0251] Exemplarily, the terminal may also use time information such as Paging Occasion and SFN as the input for mapping or operation to obtain an index corresponding to a set of non-orthogonal transmission modes and the corresponding signature indexes.

[0252] Exemplarily, for the case where the signature is not a discrete value, such as the power allocation factor, an operation method may also be directly defined to directly obtain the signature value without obtaining an index.

[0253] In some embodiments, when the first information is the configuration information at the paging record list granularity, the first information is a new field in the paging record list, and the first information includes one of the following: a second container, a third container, and a second parameter group;

[0254] Wherein, the second container includes at least two first sub-containers, and each of the at least two first sub-containers includes non-orthogonal transmission modes configured for at least two terminals respectively and the associated signature information;

[0255] Wherein, the third container includes non-orthogonal transmission modes and the associated signature information that are effective for at least two paging records respectively;

[0256] Wherein, the second parameter group includes a set of non-orthogonal transmission modes and the associated signature information that are effective for all terminals corresponding to the paging record list.

[0257] Exemplarily, a new configuration field (i.e., the first information) is introduced in the PagingRecordList to indicate that all UEs in the RecordList adopt a non-orthogonal transmission mode of SDT (such as MT-SDT or MO-SDT) and the corresponding Signature.

[0258] Specifically, for example, the new configuration field (i.e., the first information) in the PagingRecordList can be a container (i.e., the second container) containing multiple PagingRecord parameter containers, or a container (i.e., the third container) containing multiple parameter containers effective for each PagingRecord, or a set of parameters (i.e., the second parameter set) effective for all UEs. For the container containing multiple PagingRecord parameter containers (i.e., the second container), it is still configured per Paging UE, but in the form of a two-layer container in the PagingRecordList. For the container containing multiple parameter containers effective for each PagingRecord (i.e., the third container), a group of UEs in one Record will reuse the same parameters, and some methods are needed to obtain different parameters per UE according to a set of the same parameters, according to mapping or randomization methods, that is, the non-orthogonal transmission modes and Signatures actually adopted by UEs are not completely the same. For the set of parameters (i.e., the second parameter set) effective for all UEs, all UEs in all Records in the PagingRecordList will reuse the same parameters, and some methods are needed to obtain different parameters per UE according to a set of the same parameters, according to mapping or randomization methods, that is, the non-orthogonal transmission modes and Signatures actually adopted by UEs are not completely the same.

[0259] Optionally, when the first information includes the third container or the second parameter set, each terminal determines the corresponding non-orthogonal transmission mode and the associated signature information based on at least one of the following:

[0260] Part or all of the terminal identifiers (UE IDs), paging occasion (PO), system frame number (SFN), preset parameters (which can also be preset operation methods).

[0261] In some embodiments, when the first information is configuration information at the paging message granularity, the first information is a new field in the paging message, and the first information includes one of the following: a fourth container, a fifth container, a sixth container, a third parameter set;

[0262] Among them, the fourth container includes at least two second sub - containers, the at least two second sub - containers include at least two third sub - containers, and each of the at least third sub - containers includes a non - orthogonal transmission mode configured for at least two terminals respectively and the associated signature information;

[0263] Among them, the fifth container includes at least two fourth sub - containers, and each of the at least two fourth sub - containers includes a non - orthogonal transmission mode effective for at least two paging records respectively and the associated signature information;

[0264] Among them, the sixth container includes a non - orthogonal transmission mode effective for at least two paging record lists respectively and the associated signature information;

[0265] Among them, the third parameter group includes a set of non - orthogonal transmission modes effective for all terminals corresponding to the paging record list and the associated signature information.

[0266] Exemplarily, a new configuration field (i.e., the first information) is introduced in the Paging message to indicate that all UEs in the Paging message adopt a non - orthogonal transmission mode of SDT (such as MT - SDT or MO - SDT) and the corresponding Signature.

[0267] Specifically, for example, the new configuration field (i.e., the first information) in the Paging message can be a three - layer container (container) containing multiple PagingRecordList parameters (granularity to per Paging UE) (i.e., the fourth container), or a two - layer container (container) of PagingRecordList parameters (granularity to per PagingRecord) (i.e., the fifth container), or a one - layer container (container) of PagingRecordList parameters (granularity to per PagingRecordList) (i.e., the sixth container), or effective for all UEs (i.e., the third parameter group).

[0268] Optionally, when the first information includes the fifth container or the sixth container or the third parameter group, each terminal determines the corresponding non - orthogonal transmission mode and the associated signature information based on at least one of the following:

[0269] Part or all of the terminal identifiers, paging occasion, SFN, preset parameters (which can also be preset operation methods).

[0270] Therefore, in the embodiments of the present application, the first downlink data and at least one paging message can be multiplexed and transmitted on the same time-frequency resource based on M non-orthogonal transmission modes and the signature information associated with the M non-orthogonal transmission modes, or at least two data units obtained by splitting the first downlink data and at least one paging message can be multiplexed and transmitted on the same time-frequency resource based on M non-orthogonal transmission modes and the signature information associated with the M non-orthogonal transmission modes, or a data unit obtained by combining the first downlink data and at least two paging messages can be multiplexed and transmitted on the same time-frequency resource based on M non-orthogonal transmission modes and the signature information associated with the M non-orthogonal transmission modes, or the first downlink data and at least one downlink data can be multiplexed and transmitted on the same time-frequency resource based on M non-orthogonal transmission modes and the signature information associated with the M non-orthogonal transmission modes, that is, the downlink data can be non-orthogonally transmitted based on M non-orthogonal transmission modes and the signature information associated with the M non-orthogonal transmission modes, which can improve the downlink data transmission capacity (including the number of concurrent users and transmission throughput) in the idle or deactivated state. Or, the first uplink data and at least one uplink data can be multiplexed and transmitted on the same time-frequency resource based on N non-orthogonal transmission modes and the signature information associated with the N non-orthogonal transmission modes, that is, the uplink data can be non-orthogonally transmitted based on N non-orthogonal transmission modes and the signature information associated with the N non-orthogonal transmission modes, which can improve the uplink data transmission capacity (including the number of concurrent users and transmission throughput) in the idle or deactivated state.

[0271] In the data non-orthogonal transmission method provided by the embodiments of the present application, the execution subject can be a data non-orthogonal transmission device, or a processing unit in the data non-orthogonal transmission device for executing the data non-orthogonal transmission method. In the embodiments of the present application, the data non-orthogonal transmission method is executed by the data non-orthogonal transmission device as an example to illustrate the data non-orthogonal transmission device provided by the embodiments of the present application.

[0272] Figure 6 FIG. shows a schematic block diagram of a data non-orthogonal transmission device 300 according to an embodiment of the present application. As Figure 6 shown, the data non-orthogonal transmission device 300 includes:
