[0091] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0092] 1. Paging Classification

[0093] In New Radio (NR), paging can be categorized into the following types based on the source of the message:

[0094] 5G Core Network (5GC) paging comes from 5GC. When downlink data arrives for a User Equipment (UE) in Radio Resource Control Idle (RRC_IDLE) state, 5GC notifies the UE via a Paging message.

[0095] Radio Access Network (RAN) paging, which comes from the gNB. When downlink data arrives for a UE in Radio Resource Control Inactive (RRC_INACTIVE) state, the gNB notifies the UE to start data transmission through a RAN Paging message.

[0096] The final paging message is sent by the gNB to the UE via the air interface.

[0097] 2. Paging Channel

[0098] 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), and the data block of the PCH transport channel is carried by the PDSCH physical channel. Since the Physical Downlink Shared Channel (PDSCH) is a downlink shared physical channel, it can carry not only the PCH transport channel but also the Downlink Shared Channel (DL-SCH) transport channel. Therefore, before receiving a 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 it in this paging cycle based on whether the PDCCH physical channel carries the Paging Radio Network Temporary Identity (P-RNTI).

[0099] 3. Paging Opportunities and Paging Frames

[0100] Paging Frame (PF) and Paging Occasion (PO) are two important paging-related concepts. 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.

[0101] If the terminal knows the paging cycle, PF (paging frame), and PO (paging occasion), it can know the exact time to receive the paging message. In order to reduce the power consumption of the UE in the RRC_IDLE / RRC_INACTIVE state, the UE uses discontinuous reception (DRX) to receive paging messages. There are several PFs in a DRX cycle, and one PF corresponds to several POs. The UE only wakes up once to monitor one PO in a DRX cycle. The UE monitors one paging occasion (PO) in each DRX cycle. PO is a set of PDCCH monitoring occasions and can include multiple time slots (for example, subframes or Orthogonal Frequency Division Multiplexing (OFDM) symbols) in which paging DCI can be sent.

[0102] DRX cycle indicates the period of UE detection of paging, PF indicates the system frame for detecting paging, PO indicates the specific PDCCH monitoring occasions for detecting paging, and i_s indicates the index of PO corresponding to PF. The calculation method is as follows:

[0103] PF: (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)

[0104] i_s:i_s=floor(UE_ID / N)mod Ns

[0105] The parameters are explained as follows:

[0106] T: is the DRX cycle; there will be a cell-level indication Tc in the system message, and the RRC may also have a UE-level indication Tue. If Tue is not indicated, T = Tc. If Tue is indicated, T = min(Tc, Tue).

[0107] N: total number of PFs in T;

[0108] Ns: the number of POs corresponding to a PF

[0109] PF_offset: PF offset

[0110] UE_ID: 5G-S-TMSI mod 1024; UE's Temporary Mobile Subscriber Identify (TMSI), which uniquely identifies different UEs and is also used in random access message (Msg) 3. If the UE does not have a TMSI, UE_ID = 0 by default.

[0111] The above parameters will be indicated in PCCH-config.

[0112] 4. Paging Message

[0113] Currently, a paging message carries a PagingRecordList, which contains at least one and at most maxNrofPageRec PagingRecords. Each PagingRecord carries a paging identifier (ue_Identity) of the paged UE. That is, a paging message can indicate that at most maxNrofPageRec UEs are paged.

[0114] The paged UE has two identifiers: one for paging UEs in the idle state, namely ng-5G-S-TMSI; the other for paging UEs in the inactive state, namely fullI-RNTI. The UE receiving the paging message is in either the idle state or the inactive state.

[0115] In addition to sending a paging message, the DCI for scheduling paging may also carry a short message and indicate whether there are available timing reference signal (TRS) resources.

[0116] 5. Random Access Process

[0117] In the prior art, the random access procedure may be a contention-based random access procedure or a non-contention-based random access procedure. The random access procedure may be a four-step random access procedure (also called a Type-1 random access procedure) or a two-step random access procedure (also called a Type-2 random access procedure).

[0118] In the contention-based 4-step random access process (Random Access Channel (RACH)), the UE first sends Msg1 to the network, which includes a preamble. After the network detects the preamble, it sends Msg2 / Random Access Response (RAR) message, which includes the number of the preamble detected by the network and the uplink radio resources allocated to the UE to send Msg3. After receiving Msg2, the UE confirms that at least one of the preamble numbers carried in Msg2 is consistent with the number of the preamble it sent, and then sends Msg3 containing contention resolution information based on the resources indicated by the RAR. After receiving Msg3, the network sends Msg4 containing contention resolution information. After receiving Msg4, the UE confirms that the resolution information is consistent with the one it sent in Msg3, thus completing the 4-step random access.

[0119] The network includes uplink grant (UL grant) information in the RAR to indicate the MSG3 physical uplink shared channel (PUSCH) scheduling information, and includes RAPID (RACH preamble ID), TC-RNTI, TA, etc. If the network does not receive the MSG3 PUSCH, it can schedule the retransmission of the MSG3 PUSCH in the PDCCH scrambled by the TC-RNTI.

[0120] For the contention random access process, 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 (RO resources). This situation can be understood as a UE preamble conflict. In this case, different UEs will receive the same RAR. At this time, different UEs will transmit MSG.3PUSCH according to the scheduling information in the RAR UL grant. Since the existing technology does not support repeated transmission of MSG.3PUSCH, the network can only decode the PUSCH (including contention resolution information) sent by one UE on one MSG3PUSCH scheduling resource. 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 MSG3PUSCH, the UE considers that the contention resolution is successful. If they do not match, the contention resolution is considered unsuccessful.

[0121] If the contention resolution is unsuccessful, the UE reselects RACH transmission resources, performs PRACH transmission, and makes the next random access attempt.

[0122] In the two-step random access process 2-step RACH, the first step is that the UE sends MsgA to the network side. After receiving MsgA, the network side sends a MsgB message to the UE. If the UE does not receive MsgB within a certain period of time, the UE will increment the counter that counts the number of times MsgA is sent and resend MsgA. If the counter that counts the number of times MsgA is sent reaches a certain threshold, the UE will switch from the 2-step random access process to the 4-step random access process. MsgA includes the MsgA preamble part and the 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 resources associated with the sending of the MsgA preamble and the RO. MsgA PUSCH resources are a set of PUSCH resources configured relative to each PRACH slot, including time-frequency resources and data modulation reference signal (DMRS) resources.

[0123] 6. Small Data Transmission

[0124] The characteristic of efficient small data transmission is that for UEs in non-connected state (i.e., IDLE and INACTIVE), it avoids excessive signaling overhead caused by RRC state transition and RRC connection establishment process, and completes the purpose of small data transmission through a very simple signaling process.

[0125] A key feature of the small data transmission solution is that the UE's current Data Radio Bearer (DRB) is suspended, not released. Therefore, the UE can resume the DRB before sending a ResumeRequest message, then use RRC signaling to piggyback small data. At this point, data can be transmitted on the DRB, just like a connected UE. This avoids state transitions and achieves efficient small data transmission with minimal signaling overhead.

[0126] Because small data transmission uses DRB transmission and access stratum (AS) security is activated, small data transmission can provide necessary security protections, such as data encryption and integrity protection. From a security perspective, since the UE may have moved to another base station while in the suspended state, the security keys used by the UE to resend packets need to be updated. The update method is to perform the next key update operation based on the parameters provided to the UE by the network when it enters the suspended state for calculating the next hop key.

[0127] Small data transmissions are carried on the Dedicated Traffic Channel (DTCH) and multiplexed with the uplink RRCConnectionResumeRequest message before transmission. Similarly, any downlink reply message can also be carried on the DTCH and multiplexed with the downlink RRCConnectionRelease message. Both uplink and downlink data are encrypted using the next key after the update.

[0128] Small data can be transmitted on Msg3 PUSCH during a 4-step RACH process, on MsgA PUSCH during a 2-step RACH process, or on PUSCH resources scheduled using a configured grant configured in the RRC inactive state. Small data transmission during 2-step RACH and 4-step RACH processes is called RACH-based small data transmission, while small data transmission using PUSCH scheduled using a configured grant is called Configured Grant (CG)-based small data transmission.

[0129] 7. Mobile Terminated Enhanced Data Transfer (MT-EDT)

[0130] In the LTE system, the network (NW) carries the MT-EDT trigger message in a paging message. The UE then initiates the EDT process. After receiving the UE's request message (carrying the MT-EDT cause value), the NW concatenates the RRC response message with the DRB data into a protocol data unit (PDU) and sends it to the UE, ultimately enabling the reception of downlink services.

[0131] 8. RSMA ratio splitting multiple access technology

[0132] The basic idea behind rate splitting is to split the messages sent to different receivers into two parts at the transmitter: a dedicated part (dedicated data stream) and a public part (public data stream). The public part of all information is then merged into a single, integrated message and multiplexed using the downlink non-orthogonal multiple access technique studied in 3GPP Rel-13, namely Multiuser Superposition Transmission (MUST). A composite constellation is designed to allocate constellation points and bits to different users. Then, similar to traditional multi-user multiple input multiple output (MU-MIMO) multi-stream transmission, the public data stream and multiple dedicated data streams are transmitted within the same time-frequency resources using different precoding and DMRS resources. On the receiver side, each user decodes not only their own dedicated data stream but also the public data stream, then merges the two data streams into a complete message. It should be noted that when decoding the public data stream, the receiver may need to decode information sent to other users and perform interference cancellation.

[0133] When all data is transmitted using a public data stream, data multiplexing is equivalent to the MUST technology studied in 3GPP Rel-13. When all data is transmitted using a dedicated data stream, data multiplexing is equivalent to the MU-MIMO method. Therefore, to a certain extent, RSMA is equivalent to a combination of the MUST and MU-MIMO methods.

[0134] 9. Downlink Non-Orthogonal Multiple Access Technology

[0135] At present, downlink non-orthogonal multiple access (NOMA) is being studied. The 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).

[0136] For example, three superposition coding methods are listed, namely Cat 1, Cat 2 and Cat 3. Among them, Cat 1 and Cat 2 superimpose multiple sub-constellations into a composite constellation, while Cat 3 directly allocates different bits to different users based on a composite constellation.

[0137] Cat1: Different sub-constellations are superimposed with an adaptive power ratio, and the mapping of composite constellation points to bits does not conform to Gray mapping principles. For example, Figure 2 shows 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 the four quadrants of the composite constellation. For example, the four points in the first quadrant, although with different values, all represent bits "00." The constellation points of the second sub-constellation are the constellation points of each cluster in the composite constellation. For example, the last two bits of the first constellation point in each quadrant represent bits "10."

[0138] Category 2: Different sub-constellations are superimposed with an adaptive power ratio, and the mapping of composite constellation points to bits conforms to the Gray mapping principle. For example, Figure 3 shows a composite constellation formed by superimposing two sub-constellations of size 4 that use the Gray mapping principle. This is similar to Figure 2, except for a slight difference in the bit mapping rules.

[0139] For Category 1 and Category 2, the composite constellation they transmit is composed of a superposition of sub-constellations, with the power ratio controlling the superposition of the sub-constellations. For the two-user scenario, the transmitting end performs the following steps: The transmitting end first determines the constellation point to be transmitted based on the first user's information bits, then multiplies this constellation point by the power ratio, where is the power ratio of the second user. Next, the transmitting end determines the constellation point to be transmitted based on the second user's information bits, and then multiplies this constellation point 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 the quadrant in which the constellation point lies to obtain the desired bit, while the second user needs to determine not only the quadrant in which the constellation point lies, but also its specific position within the quadrant. In other words, the first user can demodulate only two bits, while the second user actually needs to demodulate four bits and then extract the final two bits.

[0140] Category 3: Directly divide bits into a constellation point that conforms to the Gray mapping rule. As shown in Figure 4, the entire constellation diagram conforms to the Gray mapping rule. It is then agreed that the first two bits are the bits of the first user, and the last two bits are the bits of the second user.

[0141] It can be seen that the sub-constellations of Cat1 and Cat2 can be different, and the composite constellation formed by superposition may be irregular, while Cat3 first defines a regular composite constellation and then divides the bits.

[0142] For downlink NOMA, fully leveraging the channel conditions of different users is key to improving overall spectral efficiency. For example, for users with poor channels, such as those farther from the transmitter, constellation point resolution is poor. They can only distinguish constellation points with large Euclidean distances, such as those located in different quadrants, but cannot accurately determine constellation points within the same quadrant. On the other hand, for users with better channels, such as those closer to the transmitter, constellation point resolution is better, allowing accurate determination even of constellation points with small Euclidean distances. This effectively decodes all bits sent by the transmitter and then extracts the bits of interest. In practical applications, directly determining the composite constellation points to obtain all bits and then extracting a subset of the bits is computationally more complex. A less complex approach is SIC: first determine the sub-constellation point with a large Euclidean distance (i.e., the constellation point sent to the distant user), then remove this sub-constellation point from the received signal (vector difference), and then determine the sub-constellation point with a small Euclidean distance.

[0151] At least some of the user data.

[0152] That is, the first device as the receiving end will receive the public data stream or the private data stream sent by the second device as the sending end. Since the public data stream or the private data stream includes at least one of a paging message, a paging control message, a short message, a short message control message, data transmission control information and at least part of the user data, the above content can be reasonably allocated to the public data stream or the private data stream, thereby improving the system capacity while ensuring the robustness of the transmission to a certain extent.

[0153] In this embodiment, the first device may be a terminal, and the second device may be a network-side device. The terminal receives at least one of a paging message, a paging control message, a short message, a short message control message, data transmission control information, and at least a portion of user data sent by the network-side device. For example, at least a portion of the user data is transmitted simultaneously with the paging message or other items on a public data stream or a dedicated data stream. Alternatively, the first device may be a network-side device, and the second device may be a terminal. The network-side device receives at least a portion of the user data sent by the terminal, and the at least a portion of the user data is transmitted on a public data stream or a dedicated data stream.

[0154] Of course, in this embodiment, the paging message may also be other messages, which are transmitted via the control channel or the data channel scheduled by the control channel.

[0155] Optionally, the paging control message is used to schedule subsequent paging message transmission, the short message control message is used to schedule subsequent short message transmission, and the data transmission control information is used to schedule subsequent data transmission.

[0156] Optionally, the first device receives a public data stream or a proprietary data stream sent by the second device, including:

[0157] The first device receives the public data flow or the dedicated data flow in an idle state or an inactive state.

[0158] That is, the public data stream or the proprietary data stream can be transmitted in the idle or inactive state of the terminal. When the first device is a terminal, the terminal receives the downlink public data stream or the proprietary data stream in its idle or inactive state; when the first device is a network-side device, the network-side device receives the uplink public data stream or the proprietary data stream in the idle or inactive state of the terminal.

[0159] Optionally, the user data is small data, so the terminal and the network side device transmit small data via the public data stream or the dedicated data stream.

[0160] Optionally, the first device receives a public data stream or a proprietary data stream sent by the second device, including:

[0161] The first device receives the common data stream or the dedicated data stream sent by the second device in a rate division multiple access manner.

[0162] Here, the public data flow is also called the public data flow.

[0163] Optionally, when the public data stream includes at least part of the user data, the at least part of the user data satisfies at least one of the following:

[0164] The transmission amount is less than or equal to a first threshold;

[0165] corresponding to the first user, wherein the first user is one or more users among the paged users when the number of paged users is greater than or equal to the second threshold;

[0166] corresponding to the second user, the second user being one or more users among the third users when the number of third users is greater than or equal to a third threshold, wherein the third user is a user that is paged and has data transmission;

[0167] Corresponding to a fourth user, the number of data blocks of the fourth user is greater than or equal to a fourth threshold;

[0168] The corresponding data transmission priority is a specific value.

[0169] That is, if the public data stream includes at least part of the user data, the transmission volume of the at least part of the user data needs to be less than or equal to the first threshold, and the at least part of the user data may be the user data of one or more users, that is, a small amount of user data can be placed on the public data stream; the at least part of the user data may be the user data of one or more paged users when the number of paged users is greater than or equal to the second threshold; the at least part of the user data may be the user data of one or more users who are paged and have data transmission when the number of users who are paged and have data transmission is greater than or equal to the third threshold; the at least part of the user data may be the user data of one or more users whose number of data blocks is greater than or equal to a fourth threshold. If the number of data blocks corresponding to the user data of a certain user is greater than or equal to the fourth threshold and cannot be completely placed on the dedicated data stream, part of the user data of the user is placed on the public data stream; the at least part of the user data may be user data with a specific data transmission priority.

[0170] The first threshold, the second threshold, the third threshold, the fourth threshold, and the specific value may be specified by a network configuration or protocol. The transmission volume may be determined at a data block granularity or a transmission block granularity.

[0171] Optionally, the data transmission priority is determined by at least one of the following:

[0172] Transmission reliability requirements;

[0173] Transmission delay requirements;

[0174] Business type;

[0175] The type of transfer target.

[0176] That is, for a user data, the data transmission priority of the user data will be determined based on at least one of its transmission reliability requirements, transmission delay requirements, service type, and transmission target type, and then it will be determined whether to carry it on the public data stream.

[0177] The transmission target refers to the type of the target receiving end of at least part of the user data.

[0178] Optionally, in this embodiment, the first device receiving the common data stream sent by the second device includes:

[0179] In a case where the number of layers of the common data stream or the number of layers of the dedicated data stream is greater than or equal to a fifth threshold, the first device receives the common data stream including the at least part of the user data.

[0180] That is, when the number of layers of the public data stream or the number of layers of the private data stream is greater than or equal to the fifth threshold, the public data stream includes at least part of the user data.

[0181] The fifth threshold may be specified by a network configuration or protocol. The layer number of the public data flow or the layer number of the private data flow is a configured layer number.

[0182] Optionally, in this embodiment, when the proprietary data stream includes at least part of the user data, the at least part of the user data satisfies at least one of the following:

[0183] The transmission amount is greater than or equal to a sixth threshold;

[0184] corresponding to the fifth user, the fifth user being one or more users among the paged users when the number of paged users is greater than or equal to a seventh threshold;

[0185] corresponding to the sixth user, the sixth user being one or more users among the seventh users when the number of the seventh users is greater than or equal to an eighth threshold, wherein the seventh user is a user that is paged and has data transmission;

[0186] Corresponding to an eighth user, the number of data blocks of the eighth user is greater than or equal to a ninth threshold;

[0187] Corresponding to the eleventh user, the layer identifier corresponding to the eleventh user is within the range of layers supported by the dedicated data stream.

[0188] That is, if the dedicated data stream includes at least part of the user data, the transmission volume of the at least part of the user data needs to be greater than or equal to the sixth threshold. The at least part of the user data may be the user data of one or more users, that is, a large amount of user data can be placed on the dedicated data stream; the at least part of the user data may be the user data of one or more paged users when the number of paged users is greater than or equal to the seventh threshold; the at least part of the user data may be the user data of one or more users who are paged and have data transmission when the number of users who are paged and have data transmission is greater than or equal to the eighth threshold; the at least part of the user data may be the user data of one or more users whose number of data blocks is greater than or equal to the ninth threshold; the at least part of the user data may be the user data of one or more users whose corresponding layer identifiers (IDs) are within the layer range supported by the dedicated data stream.

[0189] Here, the layer range supported by the proprietary data stream is determined by the layer of the configured proprietary data stream.

[0190] Among them, the sixth threshold, the seventh threshold, the eighth threshold, and the ninth threshold may be specified by network configuration or protocol.

[0191] Of course, if the seventh threshold and the second threshold are both equal to N1, then when the number of paged users is greater than or equal to N1, the majority of the user data of the paged user can be placed in the dedicated user data stream, and a small amount of user data can be placed in the public data stream. If the eighth threshold and the third threshold are both equal to N2, then when the number of paged users with data transmission is greater than or equal to N2, the majority of the user data of the paged users with data transmission can be placed in the dedicated user data stream, and a small amount of user data can be placed in the public data stream. If the ninth threshold and the fourth threshold are both equal to N3, then when the number of user data blocks is greater than or equal to N3, the majority of the user data of these users can be placed in the dedicated user data stream, and a small amount of user data can be placed in the public data stream.

[0192] Optionally, in this embodiment, the first device receiving the proprietary data stream sent by the second device includes:

[0193] In at least one of the following cases, the first device receives a proprietary data stream including the at least part of the user data:

[0194] The number of layers of the common data stream is less than or equal to a tenth threshold;

[0195] The number of layers of the proprietary data stream is greater than or equal to an eleventh threshold;

[0196] The transmission amount of user data and non-user data is greater than or equal to a twelfth threshold.

[0197] That is, if at least one of the following situations occurs: the number of layers of the public data stream is less than or equal to the tenth threshold, the number of layers of the private data stream is greater than or equal to the eleventh threshold, and the transmission volume of user data and non-user data is greater than or equal to the twelfth threshold, at least part of the user data will be placed on the private data stream.

[0198] Here, the non-user data includes at least one of a paging message, a paging control message, a short message, a short message control message, and data transmission control information.

[0199] Among them, the tenth threshold, the eleventh threshold, and the twelfth threshold may be specified by network configuration or protocol.

[0200] Optionally, in this embodiment, the first device receiving the proprietary data stream sent by the second device includes:

[0201] In at least one of the following cases, the first device receives a proprietary data stream including at least part of the control information:

[0202] The amount of the control information is greater than or equal to a thirteenth threshold;

[0203] The number of paged users is less than or equal to a fourteenth threshold;

[0204] The number of users being paged and having data transmission is less than or equal to a fifteenth threshold;

[0205] The number of layers of the common data stream is less than or equal to a sixteenth threshold;

[0206] The number of layers of the proprietary data stream is greater than or equal to a seventeenth threshold;

[0207] The control information includes at least one of the following:

[0208] paging messages;

[0209] Paging control message;

[0210] Short messages;

[0211] Short message control message;

[0212] Data transmission control information.

[0213] That is, under certain circumstances, at least one of the following: a paging message, a paging control message, a short message, a short message control message, or data transmission control information will be placed on the dedicated data stream. These circumstances include, but are not limited to: the amount of control information is greater than or equal to a thirteenth threshold, meaning the amount of control information is large and needs to be partially placed on the dedicated data stream; the number of paged users is less than or equal to a fourteenth threshold, meaning the amount of user data is small and the dedicated data stream can be used to store at least part of the control information; the number of paged users with data transmission is less than or equal to a fifteenth threshold, meaning the amount of user data is small and the dedicated data stream can be used to store at least part of the control information; the number of layers in the public data stream is less than or equal to a sixteenth threshold, meaning the public data stream is insufficient to store all the control information and needs to be partially placed on the dedicated data stream; and the number of layers in the private data stream is greater than or equal to a seventeenth threshold, meaning the private data stream can be used to store at least part of the control information.

[0214] Among them, the thirteenth threshold, the fourteenth threshold, the fifteenth threshold, the sixteenth threshold, and the seventeenth threshold may be specified by network configuration or protocol.

[0215] Optionally, the method further includes:

[0216] The first device receives flow-related information sent by the second device, where the flow-related information includes at least one of the following:

[0217] Whether the public data stream or the dedicated data stream is sent via rate splitting multiple access;

[0218] whether the first information is included in the common data stream;

[0219] Whether the first information is included in the proprietary data stream.

[0220] In this way, the receiving end of the dedicated data stream and the public data stream can understand through the stream-related information whether the public data stream or the private data stream is sent through rate splitting multiple access, whether the first information is contained in the public data stream, and whether the first information is contained in the private data stream, so as to effectively obtain the required content. If the stream-related information includes whether the public data stream or the private data stream is sent through rate splitting multiple access, the first device can determine whether to receive the public data stream or the private data stream based on the rate splitting multiple access method based on the stream-related information.

[0221] The first information includes at least one of a paging message, a paging control message, a short message, a short message control message, and data transmission control information.

[0222] Optionally, the flow related information may be configured by the network and sent by the network side device to the terminal, for example, the network side device carries it in paging downlink control information (paging DCI).

[0223] Optionally, the method further includes:

[0224] The first device receives indication information sent by the second device, where the indication information is used to indicate whether user data of the paged user exists.

[0225] In this way, the first device can learn whether the paged user has user data through the indication information, so as to determine whether to receive the user data.

[0226] Optionally, the indication information may be configured by the network and sent by the network side device to the terminal. For example, the network side device indicates in the paging DCI whether multiple paging users have user data.

[0227] Optionally, in this embodiment, the method further includes:

[0228] The first device determines first flow information of the common data flow, where the first flow information includes at least one of the following:

[0229] User corresponding layer information;

[0230] The number of configured layers;

[0231] The number of transmission blocks for the user.

[0232] Here, the user-specific layer information may include each user's corresponding layer ID, the modulation or coding scheme used by each user's corresponding layer, the number of layers required by each user, and so on. The configured number of layers may be the number of layers supported by the common data stream, such as that configured by the network-side device. Furthermore, the first stream information may also include the position number of each user in the paging message, etc., which are not listed here.

[0233] Optionally, the first device determining the first flow information of the common data flow includes:

[0234] The first device performs at least one of the following:

[0235] receiving the first flow information sent by the second device;

[0236] The first flow information is determined based on at least one of the following:

[0237] The user being paged;

[0238] Users who are paged and have data transmission;

[0239] A user who is paged and has data transmission with a data volume greater than or equal to the eighteenth threshold.

[0240] That is, the first flow information of the public data flow may be notified by the second device, or may be independently determined by the first device based on at least one of the above items.

[0241] Among them, the way in which the first device determines the first stream information based on the paged user can be that the number of users to be paged is used as the number of configured layers; the position number of the user to be paged in the paging message is used as the layer ID of each user; the UE IDs of the users to be paged are sorted in a certain order (such as from small to large) and numbered in sequence as the layer ID of each user. For example, assuming that there are 4 UEs being paging, and UE ID = 10, 15, 20, 21, it can be determined that the control information of these UEs can use layer 0, 1, 2, 3 respectively in the common data stream.

[0242] Among them, the way in which the first device determines the first stream information based on the user who is paged and has data transmission can be that the number of users who are paged and have data transmission is used as the configured layer number; the position number of the user who is paged and has data transmission in the paging message is used as the layer ID of each user; the UE IDs of the users who are paged and have data transmission are sorted in a certain order (such as from small to large) and numbered in sequence as the layer ID of each user. For example, assuming that there are 4 UEs being paging, and UE ID = 10, 15, 21, it can be determined that the control information of these UEs can use layer 0, 1, and 2 respectively in the common data stream.

[0243] The first device may determine the first flow information based on the number of users that are paged and have data transmissions with a data volume greater than or equal to an eighteenth threshold by using the number of users that are paged and have data transmissions with a data volume greater than or equal to the eighteenth threshold as the number of configured layers. The eighteenth threshold may be specified by a network configuration or protocol.

[0244] Optionally, when the first device receives the first flow information sent by the second device, the first flow information is included in at least one of the following:

[0245] first configuration information;

[0246] first indication information carried by the public data stream;

[0247] The dedicated data stream carries second indication information.

[0248] That is to say, the second device can send first configuration information containing the first stream information, and the first configuration information can be paging DCI, paging message, proprietary RRC signaling (such as RRC release message) or system message, etc.; the second device can send one or some public data streams, and the first indication information in the public data stream contains the first stream information; the second device can send one or some proprietary data streams, and the second indication information in the proprietary data stream contains the first stream information.

[0249] Optionally, the first flow information may be configured by the network and sent by the network-side device to the terminal.

[0250] Optionally, in this embodiment, the method further includes:

[0251] The first device determines second flow information of the dedicated data flow, where the second flow information includes at least one of the following:

[0253] Target number of users;

[0254] Transmission scheme information;

[0255] Precoding information;

[0256] Associated reference signal information.

[0257] Among them, the resources associated with the layer can be DMRS port, precoding (precoder), and different bit positions corresponding to the modulation symbol, and the resource information corresponding to the user and associated with the layer can be the DMRS port information corresponding to the user, the precoding information corresponding to the user, and the different bit positions corresponding to the modulation symbol corresponding to the user. The number of target users can be the number of multiplexed users, such as the number of users corresponding to at least part of the user data transmitted together with the paging message in the public data stream. The transmission scheme information can be codebook-based transmission or non-codebook-based transmission. The precoding information is the precoding information of each dedicated data stream, and the precoding information of each dedicated data stream can be the same or different. The associated reference signal information is the reference signal information associated with each dedicated data stream, and the reference signal information associated with each dedicated data stream can be the same or different.

[0258] Optionally, the first device determines the second flow information of the proprietary data flow, including:

[0259] The first device performs at least one of the following:

[0260] receiving the second flow information sent by the second device;

[0261] The second flow information is determined based on at least one of the following:

[0262] The user being paged;

[0263] Users who are paged and have data transmission;

[0264] A user who is paged and has data transmission with a data volume greater than or equal to a nineteenth threshold.

[0265] That is, the second flow information of the proprietary data flow may be notified by the second device, or may be independently determined by the first device based on at least one of the above items.

[0266] The manner in which the first device determines the second flow information based on the paged users may be to use the number of paged users as the number of multiplexed users.

[0267] Among them, the way in which the first device determines the second flow information based on the users who are paged and have data transmission can be to use the number of users who are paged and have data transmission as the number of multiplexed users; and the position number of the users who are paged and have data transmission in the paging message as the number of multiplexed users.

[0268] The first device may determine the second flow information based on users that are paged and have data transmissions with a data volume greater than or equal to a nineteenth threshold by using the number of users that are paged and have data transmissions with a data volume greater than or equal to the nineteenth threshold as the target number of users. The nineteenth threshold may be specified by a network configuration or protocol.

[0269] Optionally, in this embodiment, when the first device receives the second flow information sent by the second device, the second flow information is included in at least one of the following:

[0270] Second configuration information;

[0271] third indication information carried by the public data stream;

[0272] The fourth indication information carried by the proprietary data stream.

[0273] The second device can send second configuration information including the second stream information, which can be paging DCI, paging message, proprietary RRC signaling (such as RRC release message) or system message, etc.; the second device can send one or more public data streams, and the third indication information in the public data stream includes the second stream information; the second device can send one or more private data streams, and the fourth indication information in the private data stream includes the second stream information.

[0274] Optionally, in this embodiment, the layer sequence corresponding to the public data stream is the same as the layer sequence corresponding to the proprietary data stream.

[0275] Here, the layer order is the order of resources associated with the layer, such as multiple DMRS ports in a specific order (DMRS port 0, 1, ...), multiple precoders in a specific order (first, second, ..., Nth precoder), and the order of different bit positions corresponding to the modulation symbols.

[0276] Taking DMRS port as an example, assuming there are four users, the public data stream is {layer 0, user 0}, {layer 1, user 3}, {layer 2, user 2}, {layer 3, user 1}. The dedicated data stream is {layer 0, DMRS port 0, user 0}, {layer 1, DMRS port 1, user 3}, {layer 2, DMRS port 2, user 2}, {layer 3, DMRS port 3, user 1}.

[0277] It should be noted that, in this embodiment, the layer order of the user in the dedicated data stream may be determined by network configuration, protocol provisions, or according to certain rules during retransmission.

[0278] For example, a layer change pattern with repeated transmissions can be introduced to enable multiple users to change layers at different times. Assume that a user has four transmissions, and the layer order of these four transmissions in the dedicated data stream is {Transmission 0, DMRS port 0, layer 0}, {Transmission 1, DMRS port 1, layer 3}, {Transmission 2, DMRS port 2, layer 2}, {layer 3, DMRS port 3, layer 1}.

[0279] In the embodiment of the present application, the proprietary data stream can be transmitted in a transparent multi-layer transmission or in a non-transparent multi-layer transmission. Specifically, the network side device indicates whether the proprietary data stream transmission is transparent transmission or non-transparent transmission.

[0280] Optionally, data can be transmitted via RSMA, supporting transparent or non-transparent multi-layer proprietary data stream transmission.

[0281] In addition, in this embodiment, for a user with a large amount of data, the user data of the user can be split into multiple transport blocks (TB). Optionally, the method further includes:

[0282] In a case where the user data of the ninth user corresponds to multiple transport blocks, the first device determines, based on sizes of the multiple transport blocks, whether each transport block is located in the common data stream or the dedicated data stream.

[0283] That is, for the ninth user, it is determined whether the multiple transmission blocks are located in the common data stream or the dedicated data stream, thereby completing the transmission or reception of the common data stream or the dedicated data stream.

[0284] For the ninth user, all of its transmission blocks may be placed in the dedicated data stream; all of its transmission blocks may be placed in the public data stream; or part of its transmission blocks may be placed in the dedicated data stream and part of its transmission blocks may be placed in the public data stream.

[0285] Specifically, when some of its transmission blocks are placed in the dedicated data stream and some of its transmission blocks are placed in the public data stream, which transmission blocks are placed in the dedicated data stream and which transmission blocks are placed in the public data stream are determined based on the size of the transmission blocks. For example, large transmission blocks are placed in the dedicated data stream and small transmission blocks are placed in the public data stream. The transmission block size can be determined based on whether the transmission block is larger than or not smaller than a certain threshold, and the threshold can be defined by the network configuration or protocol.

[0286] Optionally, RSMA transmission supports multiple transport blocks for a single user. For example, for single-user uplink data transmission, when the transport block exceeds a certain size, RSMA multiplexing can be used for transmission.

[0287] Optionally, in this embodiment, when the user data of the tenth user corresponds to multiple transport blocks, the layer order corresponding to the multiple transport blocks in the common data stream or the dedicated data stream is one of the following:

[0288] A size order of the plurality of transport blocks;

[0289] The control information of the plurality of transport blocks is in an order corresponding to the data stream;

[0290] The layer order of network-side device configuration.

[0291] That is, the user data of the tenth user corresponds to multiple transport blocks placed on the public data stream or the private data stream. The layer order of the multiple transport blocks in the public data stream or the private data stream is the size order of the multiple transport blocks, or the order of the control information of the multiple transport blocks in the corresponding data stream, or the layer order configured by the network-side device. Of course, the layer order of the multiple transport blocks in the public data stream or the private data stream can also be inconsistent, but can satisfy a specific relationship, such as the opposite.

[0292] Specifically, multiple transport blocks of the tenth user are placed on the dedicated data stream, and the layer order of the multiple transport blocks in the dedicated data stream can be consistent with the layer order of the control information common data stream of the multiple transport blocks or satisfy a specific relationship.

[0293] Specifically, the network-side device configures the layer order by sending paging DCI.

[0294] Optionally, in this embodiment, the multiple transmission blocks of the ninth user or the tenth user are transmission blocks including different data, or are repeated transmission blocks including the same data.

[0295] When multiple transmission blocks include the same data, repeated transmission of the same data block can be achieved at different layers, thereby improving the reception reliability of the transmission blocks.

[0296] It should be noted that, in the embodiment of the present application, the at least part of the user data may be, but is not limited to, small data or normal data of an idle or inactive terminal.

[0297] In summary, the methods of the embodiments of the present application introduce efficient data stream allocation to increase the number of multi-user data transmissions and the throughput of single-user data transmissions in the idle or inactive state. Furthermore, the present invention also considers the repeated transmission of a data block across multiple streams to improve transmission reliability.

[0298] As shown in FIG6 , a transmission method according to an embodiment of the present application includes:

[0299] Step 601: The second device sends a public data stream or a private data stream to the first device; wherein the public data stream or the private data stream includes at least one of the following:

[0300] paging messages;

[0301] Paging control message;

[0302] Short messages;

[0303] Short message control message;

[0304] Data transmission control information;

[0305] At least some of the user data.

[0306] That is, the second device as the sending end will send a public data stream or a private data stream to the first device as the receiving end. Since the public data stream or the private data stream includes at least one of a paging message, a paging control message, a short message, a short message control message, data transmission control information and at least part of the user data, the above content can be reasonably allocated to the public data stream or the private data stream, while improving the system capacity and ensuring the robustness of the transmission to a certain extent.

[0307] In this embodiment, the first device may be a terminal, and the second device may be a network-side device. The terminal receives at least one of a paging message, a paging control message, a short message, a short message control message, data transmission control information, and at least a portion of user data sent by the network-side device. For example, at least a portion of the user data is transmitted simultaneously with the paging message on a public data stream or a dedicated data stream. Alternatively, the first device is a network-side device, and the second device is a terminal. The network-side device receives at least a portion of the user data sent by the terminal, and the at least a portion of the user data is transmitted on a public data stream or a dedicated data stream.

[0308] Optionally, the second device sends a public data stream or a proprietary data stream to the first device, including:

[0309] The second device sends the public data flow or the dedicated data flow in an idle state or an inactive state.

[0310] That is, the public data stream or the proprietary data stream can be transmitted in the idle or inactive state of the terminal. When the second device is a terminal, the terminal sends the uplink public data stream or the proprietary data stream in its idle or inactive state; when the second device is a network-side device, the network-side device sends the downlink public data stream or the proprietary data stream in the idle or inactive state of the terminal.

[0311] Optionally, the second device sends a public data stream or a proprietary data stream to the first device, including:

[0312] The second device sends the public data stream or the dedicated data stream in a rate division multiple access manner.

[0313] Optionally, when the public data stream includes at least part of the user data, the at least part of the user data satisfies at least one of the following:
