[0137] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other information transmission methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0138] In some embodiments, semi-persistent scheduling (SPS) transmission allows terminals to use pre-configured uplink / downlink resources from network devices for data transmission and reception, saving Physical Downlink Control Channel (PDCCH) resources used for each dynamically scheduled uplink / downlink transmission. Typically, SPS resources are reserved by the network for specific terminals, eliminating contention; if a terminal does not transmit or receive data, these resources are wasted.

[0139] In some embodiments, for the sake of terminal complexity, the NB-IoT UE only receives a few PDCCHs scrambled with Radio Network Temporary Identifier (RNTI) in connected mode, such as only receiving PDCCHs scrambled with Cell-Radio Network Temporary Identifier (C-RNTI), Radio Access Network Temporary Identifier (RA-RNTI), or Temporary (T) C-RNTI.

[0140] In some embodiments, to improve uplink capacity, NB-IoT UEs can support contention-based (CB) SPS uplink transmission in connected mode, i.e., CB-SPS. In non-terrestrial networks (NTNs), to further reduce conflicts on CB-SPS resources, it can be considered to combine it with DSA or contention resolution diversity slotted ALOHA (CRDSA) technology. DSA or CRDSA transmissions involve multiple transmission copies (replica packets containing the same content). When receiving base station responses, the terminal needs to use multiple RNTIs associated with multiple transmission resources; therefore, it is necessary to enhance the capabilities of the NB-IoT UE. The base station needs to know the UE's capabilities to configure connected-mode transmissions.

[0141] Figure 2 is an interactive schematic diagram of an information transmission method according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to an information transmission method for a communication system 100; the method includes:

[0142] Step 2101: The terminal sends the first message.

[0143] The first piece of information is used to indicate whether the terminal supports the ability to send multiple copy packets, wherein the multiple copy packets contain the same content.

[0144] In some embodiments, the aforementioned multiple replication packets may be generated based on diversity slotted ALOHA (DSA) technology.

[0145] In some embodiments, the aforementioned multiple replicated packets can be generated based on Contention Resolution Diversity Slotted ALOHA (CRDSA) technology. That is, the terminal can send uplink packets and replicated packets containing the same content at different times. Furthermore, if a replicated packet is successfully decoded at a certain time, the receiving end can use this information to eliminate interference from that packet at other times, thereby further decoding other conflicting packets.

[0146] In some embodiments, the terminal supports the ability to send multiple copy packets, which can be achieved by supporting DSA CB-SPS capability. That is, the terminal supports the use of CB-SPS resources to transmit copy packets generated based on DSA technology.

[0147] In some embodiments, the terminal supports the ability to send multiple replication packets, and can support DSA CB Configured Grant (CG) capability. That is, the terminal supports using CB-CG resources to transmit replication packets generated based on DSA technology.

[0148] In some embodiments, the terminal supports the ability to send multiple replication packets, which can be achieved by supporting CRDSA CB-SPS capability. That is, the terminal can utilize CB-SPS resources to transmit replication packets generated based on CRDSA technology.

[0149] In some embodiments, the terminal supports the ability to send multiple copy packets, which can be achieved by supporting CRDSA CB-CG capability. That is, the terminal can utilize CB-CG resources to transmit copy packets generated based on CRDSA technology.

[0150] In some embodiments, the first information may be indicated by the first logical channel identifier (LCID) in the common control channel (CCCH) of message (Msg)3, or by the first enhanced logical channel identifier (eLCID).

[0151] In some embodiments, the first LCID or the first eLCID can be newly defined.

[0152] For example, if a terminal supports the ability to send multiple replicated packets, it can carry a newly defined first LCID or first eLCID in the CCCH of the randomly accessed Msg3 to indicate to the network device that it supports the ability to send multiple replicated packets.

[0153] In some embodiments, the first LCID or the first eLCID is further used to indicate that the maximum number of Radio Network Temporary Identifiers (RNTIs) that the terminal can listen to in the connected state is a specified value.

[0154] In some embodiments, the specified value can be a value agreed upon in the protocol, such as N values, or a value indicated by the network device. This disclosure does not limit this.

[0155] For example, if a Narrow Band Internet of Things (NB-IoT) terminal supports sending multiple replica packets and the maximum number of RNTIs that can be listened to in the connected state is a specified value, then the terminal can carry a newly defined first LCID or first eLCID in the CCCH of Msg3 to indicate to the network device that it supports sending multiple replica packets and that the maximum number of RNTIs that can be listened to in the connected state is N (a specified value indicated by the protocol or network device).

[0156] In some real-time scenarios, the maximum number of RNTIs that an endpoint can listen to in connected mode can be the number of RNTIs used for response messages corresponding to multiple replication packets. That is, the maximum number of RNTIs used for DSA and / or CRDSA response messages.

[0157] For example, the maximum number of RNTIs that a terminal can listen to in the connected state is N, meaning that the terminal can send a maximum of N copy packets, and correspondingly, can listen to a maximum of N response messages corresponding to copy packets at the same time.

[0158] In some embodiments, the maximum number of RNTIs that a terminal can listen to in the connected state can be the sum of the number of RNTIs used for response messages corresponding to multiple copy packets and the number of other RNTIs.

[0159] In some embodiments, other RNTIs can be RNTIs that the terminal can listen to in the connected state, other than the response message corresponding to the replication packet. For example, other RNTIs may include, but are not limited to, at least one of C-RNTI, TC-RNTI, RA-RNTI, SPS-RNTI, etc. It should be noted that the above description of other RNTIs is only illustrative and should not be construed as a restrictive description of the RNTIs included in other RNTIs.

[0160] In some embodiments, if the maximum number of RNTIs that the terminal can listen to in the connected state is the sum of the number of RNTIs used for response messages corresponding to multiple replication packets and the number of other RNTIs, since the other RNTIs do not necessarily need to be listened to by the terminal at the same time, the network device can determine the number of replication packets that the terminal can send based on the maximum number of RNTIs that the terminal can listen to in the connected state and the number of other RNTIs that need to be listened to at the same time.

[0161] For example, a terminal can listen to a maximum of N RNTIs in connected state, including the number of RNTIs used for response messages corresponding to multiple replication packets and other RNTIs. If the terminal needs to listen to M other RNTIs simultaneously (M less than N), then the number of RNTIs used for response messages corresponding to multiple replication packets is NM. In other words, the terminal can send a maximum of NM replication packets, and correspondingly, can simultaneously listen to a maximum of NM response messages corresponding to replication packets.

[0162] In some embodiments, multiple first LCIDs and / or first eLCIDs are newly defined, and different first LCIDs and / or first eLCIDs correspond to different maximum RNTI counts. The terminal can then determine the LCIDs or eLCIDs included in the CCCH in Msg3 based on the maximum number of RNTIs that can be listened to in the connected state.

[0163] For example, three new LCIDs are defined: LCID#1, LCID#2, and LCID#3. LCID#1 has a maximum of 4 RNTIs, LCID#2 has 3, and LCID#3 has 2. If the terminal supports sending multiple replicated packets and can listen to a maximum of 3 RNTIs in the connected state, it can carry LCID#2 in the CCCH of Msg3.

[0164] For example, three new eLCIDs are defined: eLCID#1, eLCID#2, and eLCID#3. The maximum number of RNTIs corresponding to eLCID#1 is 4, eLCID#2 is 3, and eLCID#3 is 2. Therefore, if the terminal supports sending multiple replicated packets and the maximum number of RNTIs it can listen to in connection mode is 4, it can carry eLCID#1 in the CCCH of Msg3.

[0165] In some embodiments, after receiving the first information, the network device can accurately determine the maximum number of RNTIs that the terminal can listen to in the connected state based on the LCID or eLCID contained in the first information.

[0166] In some embodiments, the first information may also be carried by a Radio Resource Control (RRC) message in message Msg3.

[0167] In some embodiments, when requesting to establish an RRC connection, the terminal may indicate to the network device whether it supports the ability to send multiple copy packets by extending the RRC Connection Request message carried in Msg3.

[0168] In some embodiments, when a terminal requests to re-establish an RRC connection after losing the RRC connection, it can indicate to the network device whether it supports the ability to send multiple duplicate packets by extending the RRC Connection Reestablishment Request message.

[0169] In some embodiments, after an RRC connection is paused (or suspended), the terminal may, when sending an RRC recovery request to the network device, indicate to the network device whether it supports the ability to send multiple replicated packets via an RRC connection recovery request.

[0170] In some embodiments, a terminal can explicitly indicate whether it supports the ability to send multiple replicated packets through an RRC message carried in Msg3, for example, by specifying the value of a specified information field in the RRC message to the network device.

[0171] In some embodiments, the terminal can also implicitly indicate whether it supports the ability to send multiple copy packets through the RRC message carried in Msg3. For example, if the terminal supports the ability to send multiple copy packets, it can include a specified information field in the sent RRC message; if the terminal does not support the ability to send multiple copy packets, it may not include a specified information field in the sent RRC message.

[0172] In some embodiments, the terminal may further explicitly (or implicitly) indicate the maximum number of RNTIs it can listen to in connected state via an RRC message in Msg3.

[0173] In some embodiments, the terminal may explicitly indicate the maximum number of RNTIs it can listen for in connected state in the RRC message in Msg3. Alternatively, if the RRC message in Msg3 indicates that the terminal supports sending multiple copy packets, then the maximum number of RNTIs it can listen for in connected state is implicitly indicated as the specified number.

[0174] In some embodiments, the first information may also be carried by a Media Access Control (MAC) control element (CE) in Msg3.

[0175] In some embodiments, the aforementioned MAC CE can be a newly defined MAC CE, which can correspond to a newly defined LCID and / or eLCID.

[0176] In some embodiments, a terminal can explicitly indicate whether it supports the ability to send multiple replicated packets by using the newly defined MAC CE in Msg3, for example by using the value indicated by the newly defined MAC CE sub-header to explicitly indicate to the network device whether it supports the ability to send multiple replicated packets.

[0177] In some embodiments, a terminal may implicitly indicate whether it supports the ability to send multiple copy packets by including a newly defined MAC CE in Msg3. For example, if the terminal supports the ability to send multiple copy packets, it can include the newly defined MAC CE in Msg3. Alternatively, if the terminal does not support the ability to send multiple copy packets, it may not include the newly defined MAC CE in Msg3.

[0178] In some embodiments, the terminal may further explicitly (or implicitly) indicate the maximum number of RNTIs it can listen to in connected state via the MAC CE carried in Msg3.

[0179] In some embodiments, the terminal may explicitly indicate the maximum number of RNTIs it can listen for in connected mode in the MAC CE in Msg3. Alternatively, if the MAC CE in Msg3 indicates that the terminal supports sending multiple copy packets, then it implicitly indicates that the maximum number of RNTIs the terminal can listen for in connected mode is a specified number.

[0180] In some embodiments, the first information may also be carried by an RRC message in Msg5.

[0181] In some embodiments, during the RRC connection establishment process, the terminal can indicate to the network device whether it supports the ability to send multiple copy packets through the RRC connection setup complete message in Msg5.

[0182] In some embodiments, during the RRC reconstruction process, the terminal can indicate to the network device whether it supports the ability to send multiple copy packets via an RRC Connection Reestablishment Complete message.

[0183] In some embodiments, during the RRC recovery process, the terminal can indicate to the network device whether it supports the ability to send multiple copy packets via an RRC Connection Resume Complete message.

[0184] In some embodiments, the terminal may further explicitly (or implicitly) indicate the maximum number of RNTIs it can listen to in connected state via an RRC message in Msg5.

[0185] In some embodiments, the terminal may explicitly indicate the maximum number of RNTIs it can listen for in connected state in the RRC message in Msg5. Alternatively, if the RRC message in Msg5 indicates that the terminal supports sending multiple copy packets, then it implicitly indicates that the maximum number of RNTIs the terminal can listen for in connected state is the specified number.

[0186] In some embodiments, the first information may also be carried by the terminal capability information. That is, when the terminal sends the capability information to the network device, it may also carry the first information indicating whether it supports the ability to send copy packets.

[0187] In some embodiments, the first information in the terminal capability information is also used to explicitly or implicitly indicate the maximum number of RNTIs that the terminal can listen to in the connected state.

[0188] In some embodiments, the terminal may explicitly indicate the maximum number of RNTIs it can listen to in the connected state in the first information carried in the terminal capability information. Alternatively, if the first information carried in the terminal capability information indicates that the terminal supports sending multiple copy packets, then it implicitly indicates that the maximum number of RNTIs the terminal can listen to in the connected state is a specified number.

[0189] In some embodiments, the network device receives first information.

[0190] Step 2102: The network device sends the second information.

[0191] The second information is used to indicate at least one of the following: the resources corresponding to the multiple replication packets respectively, and the transmission parameters of the multiple replication packets.

[0192] In some embodiments, the resources corresponding to the multiple replica packages may include one or more of the following: frequency domain resources corresponding to the multiple replica packages, time domain resources corresponding to the multiple replica packages, and code domain resources corresponding to the multiple replica packages.

[0193] In some embodiments, the terminal carries first information via Msg3 (such as a newly defined LCID or eLCID in the CCCH of Msg3, or an RRC message or MAC CE in Msg3), and the first information indicates that the terminal supports sending multiple replica packets. In this case, the network device can configure resources corresponding to each replica packet for the terminal. This provides a condition for improving the transmission success rate of each replica packet, and at the same time improves the accuracy of the terminal in determining the RNTI of the response message corresponding to each replica packet.

[0194] In some embodiments, the terminal carries first information via Msg3, and the first information indicates that the terminal supports sending multiple copy packets. In this case, the network device can also indicate to the terminal the number of copy packets to be sent, thereby providing conditions for further improving the transmission success rate of multiple copy packets.

[0195] In some embodiments, a network device can send a second message via Msg4. For example, a network device can send the second message via an RRC connection establishment message in Msg4.

[0196] In some embodiments, the terminal receives second information.

[0197] In summary, in the above embodiments, the terminal can report to the network device whether it supports sending multiple copy packets, thereby ensuring that the network device's understanding of the terminal's capabilities is consistent with that of the terminal, providing conditions for the successful transmission of multiple copy packets and the successful reception of the response messages corresponding to the copy packets.

[0198] The information transmission method involved in the embodiments of this disclosure may include at least one of steps 2101 to 2102. For example, step 2101 may be implemented as a separate embodiment, and step 2102 may be implemented as a separate embodiment, but is not limited thereto.

[0199] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

[0236] Figure 5 is an interactive schematic diagram of an information transmission method according to an embodiment of the present disclosure. As shown in Figure 5, the present disclosure relates to an information transmission method for a communication system, which includes a network device and a terminal. The method includes at least one of the following:

[0237] Step 5101: The terminal sends the first information to the network device.

[0238] The first piece of information is used to indicate whether the terminal supports the ability to send multiple copy packets, and the multiple copy packets contain the same content.

[0239] In some embodiments, the above methods may include various optional embodiments of the methods described in the embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0240] The following is an exemplary description of the above method.

[0241] For NB-IoT UEs, is it necessary to introduce whether to support the reporting of the ability to send multiple copy packets?

[0242] For example, a terminal can report whether it supports DSA capability, or whether it supports DSA CB-SPS capability, or whether it supports DSA CB-CG capability, or whether it supports CRDSA capability, or whether it supports CRDSA CB-SPS capability, or whether it supports CRDSA CB-CG capability. The following explanation uses reporting DSA CB-SPS capability as an example.

[0243] In some embodiments, the terminal can also report the number of RNTIs that can be monitored in the connection state.

[0244] In some embodiments, a new LCID / eLCID is defined for the CCCH in MSG3 to indicate DSA CB-SPS capability.

[0245] In some embodiments, a new LCID / eLCID is defined for the CCCH in MSG3 to indicate the DSA CB-SPS capability. Furthermore, this DSA CB-SPS capability indicates that the terminal supports the reception of up to N RNTIs in the connected state, where the value of N is fixed in the protocol.

[0246] In some embodiments, multiple new LCIDs / eLCIDs are defined for the CCCH in MSG3 to indicate DSA CB-SPS capabilities. Furthermore, each new LCID / eLCID corresponds to a different maximum number of RNTIs received. For example, three LCIDs / eLCIDs are defined to correspond to a maximum of four RNTIs received, a maximum of three RNTIs received, and a maximum of two RNTIs received, respectively.

[0247] In some embodiments, DSA CB-SPS capability is indicated via an RRC message in MSG3 or a MAC CE.

[0248] In some embodiments, the terminal may indicate DSA CB-SPS capability by using an RRC Conection Request message (or an RRC Conection Reestablishment Request message or an RRC Conection Resume Request message) carried in the extended MSG3, or further indicate the maximum number of RNTIs that the UE can support receiving in connected mode.

[0249] In some embodiments, the terminal can indicate DSA CB-SPS capability by defining a new MAC CE, or further indicate the maximum number of RNTIs that the UE supports receiving in connected mode. A dedicated LCID / eLCID is defined in the protocol for this MAC CE.

[0250] In some embodiments, after receiving the DSA capability indication in MSG3, the network device can configure the DSA CB-SPS resources and transmission parameters (e.g., the number of DSA copies sent by the UE) in MSG4 (e.g., RRC connection establishment message).

[0251] In some embodiments, the terminal may indicate DSA CB-SPS capability by using the RRC Connection Setup Complete message, RRC Connection Reestablishment Complete message, or RRC Connection Resume Complete message carried in the extended MSG5, or further indicate the maximum number of RNTIs that the UE supports receiving in connected mode.

[0252] In some embodiments, the terminal may report DSA CB-SPS capability through the UE Capability Information-NB, or further indicate the maximum number of RNTIs that the UE can support receiving in connected mode.

[0253] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0254] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0255] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).

[0267] The number of RNTIs used for the response messages corresponding to the multiple copy packets;

[0268] The number of RNTIs used for the response messages corresponding to the multiple copy packets is the sum of the number of other RNTIs.

[0269] In some embodiments, the transceiver module described above is further configured to:

[0270] Receive second information, wherein the second information is used to indicate at least one of the following: the resources corresponding to the plurality of copy packets respectively, and the transmission parameters of the plurality of copy packets.
