[0208] As shown in FIG. 1A , a communication system 100 includes a network device 101 and a terminal 102 .

[0211] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0213] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0214] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0215] The embodiments of the present disclosure may be applied to non-terrestrial networks (NTN), 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 (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.17 (WiMAX (registered trademark)), IEEE 802.18 (WiMAX (registered trademark)), IEEE 802.19 (WiMAX (registered trademark)), IEEE 802.20 (WiMAX (registered trademark)), IEEE 802.21 (WiMAX (registered trademark)), IEEE 802.22 (WiMAX (registered trademark)), IEEE 802.23 (WiMAX (registered trademark)), IEEE 802.24 (WiMAX (registered trademark)), IEEE 802.25 (WiMAX (registered trademark)), IEEE 802.26 (WiMAX (registered trademark)), IEEE 802.27 (WiMAX (registered trademark)), IEEE 802.28 (WiMAX (registered trademark)), IEEE 802.29 (WiMAX (registered trademark)), IEEE 802.30 (WiMAX (registered trademark)), IEEE 802.31 (WiMAX (registered trademark)), IEEE 802.32 (WiMAX (registered trademark)), IEEE 802.33 (WiMAX ( 802.20, Ultra-WideBand (UWB), Bluetooth (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 utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0216] In some embodiments, the non-terrestrial network (NTN) is an important technology introduced by the fifth-generation mobile communication system (5G). It provides wireless resources through satellites (or UAS platforms, where UAS, unmanned aircraft systems) rather than ground base stations, as shown in Figure 1A. The link between the satellite and the terminal is called a service link, and the link between the satellite and the core network equipment is called a feeder link.

[0217] In NTN, uplink capacity enhancement is considered to serve more users simultaneously for the following reasons:

[0218] 1. The frequency band resources used for NTN are limited;

[0219] 2. Satellite coverage has a larger cell radius, and the number of users in a cell is greater than that of terrestrial networks;

[0220] 3. The transmission distance between the terminal and the satellite is relatively long. Under the premise of limited terminal transmission power, in order to improve cell coverage and transmission performance, the NTN network often needs to perform more blind retransmissions, which will greatly waste spectrum resources and reduce spectrum efficiency.

[0221] Therefore, considering user multiplexing based on orthogonal cover codes (OCC), the terminal may perform symbol or resource spreading.

[0222] In summary, for the transmission of the Physical Uplink Shared Channel (PUSCH) using OCC multi-user multiplexing, it is necessary to consider redesigning the PUSCH transmission-related processing, such as resource allocation, transport block size (TBS) calculation, modulation and coding scheme (MCS), rate matching, etc.

[0223] The information processing method and device provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0224] FIG2A is an interactive diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to an information processing method, which includes:

[0225] Step S2101: The network device 101 sends first information.

[0244] In some embodiments, the length of the OCC, the number of OCC sequences, the number of users multiplexed by the OCC, and the maximum number of users multiplexed by the OCC are the same.

[0245] In some embodiments, the first frequency domain resource is obtained by extending along a first direction based on the starting frequency domain resource in the second frequency domain resource. The first direction is the direction from the ending frequency domain resource to the starting frequency domain resource in the second frequency domain resource. That is, the frequency domain resources actually occupied by the PUSCH can be reversely extended based on the starting frequency domain resource (e.g., the start RB) in the frequency domain resources indicated by the first information.

[0246] In some embodiments, the first frequency domain resource is obtained by extending along the second direction based on the ending frequency domain resource in the second frequency domain resource. The second direction is the direction from the starting frequency domain resource to the ending frequency domain resource in the second frequency domain resource. That is, the frequency domain resources actually occupied by the PUSCH can be extended back-to-back based on the ending frequency domain resource (e.g., the end RB) in the frequency domain resource indicated by the first information.

[0247] In some embodiments, the center position of the first frequency domain resource is determined based on the RIV code corresponding to the first information. That is, the center position of the second frequency domain resource (determined by the RIV code corresponding to the first information) is the center position of the first frequency domain resource, and the frequency domain resources actually occupied by the PUSCH can be extended toward both ends based on the center position of the frequency domain resource indicated by the first information.

[0248] Step S2103: The network device 101 sends the second information.

[0249] In some embodiments, the terminal 102 receives the second information sent by the network device 101 .

[0250] In some embodiments, the second information is used to determine the time domain resources occupied by the PUSCH sent by the terminal 102 .

[0251] In each embodiment of the present application, the PUSCH sent by the terminal 102 is sent based on orthogonal cover code OCC multi-user multiplexing, that is, the terminal 102 is a user using OCC multiplexing.

[0252] In some embodiments, the second information is used to indicate a first time domain resource. The first time domain resource is the time domain resource occupied by the terminal 102 to send the PUSCH. The first time domain resource is the time domain resource occupied by a PUSCH transmission (the time domain symbol resource allocated for PUSCH in a slot, or the total number of symbols occupied by a multi-slot transport block (Transport Block Processing over multi-Slots, TBoMS) PUSCH transmission).

[0253] In some embodiments, the second information is used to indicate a second time domain resource, and the terminal 102 can determine the first time domain resource based on the second time domain resource and the second parameter. The first time domain resource is the time domain resource occupied by the PUSCH sent by the terminal 102.

[0254] In some embodiments, the name of the second information is not limited, and may be, for example, "downlink control information", "time domain resource allocation information", "time domain resource allocation", "time domain resource indication", etc.

[0255] In some embodiments, the second information may be included in a time domain resource allocation (TDRA) information field.

[0256] Step S2104: The terminal 102 determines a first time domain resource of the PUSCH.

[0257] In the embodiment of the present application, the first time domain resource is the time domain resource occupied by the PUSCH sent by the terminal 102 .

[0258] In some embodiments, the second information is used to indicate the first time domain resource.

[0259] In some embodiments, the second information is used to indicate the second time domain resource, and the terminal 102 can determine the first time domain resource based on the second time domain resource and the second parameter.

[0260] The number of time domain resource units included in the first time domain resource is the product of the number of time domain resource units included in the second time domain resource and the second parameter.

[0261] Optionally, the time domain resource unit may be a symbol, a time slot, etc., which is not limited in the embodiment of the present disclosure.

[0262] In some embodiments, the second parameter is determined based on fourth information, and the fourth information includes at least one of the following:

[0263] The length of the OCC;

[0264] The number of OCC sequences;

[0265] Number of users multiplexed by OCC;

[0266] Maximum number of users that can be multiplexed by OCC.

[0267] In some embodiments, the length of the OCC, the number of OCC sequences, the number of users multiplexed by the OCC, and the maximum number of users multiplexed by the OCC are the same.

[0268] In some embodiments, the second parameter N and the first parameter M may be the same or different.

[0269] In some embodiments, the first time domain resource is obtained by extending along a first direction based on the starting time domain resource in the second time domain resource. The first direction is the direction from the ending time domain resource to the starting time domain resource in the second time domain resource. That is, the time domain resources actually occupied by the PUSCH can be reversely extended based on the starting time domain resource (e.g., start symbol) in the time domain resources indicated by the second information.

[0270] In some embodiments, the first time domain resource is obtained by extending along a second direction based on the ending time domain resource in the second time domain resource. The second direction is the direction from the starting time domain resource to the ending time domain resource in the second time domain resource. That is, the time domain resources actually occupied by the PUSCH can be extended back-to-back based on the ending time domain resource (e.g., end symbol) in the time domain resources indicated by the second information.

[0271] In some embodiments, the center position of the first time domain resource is determined based on the SLIV code corresponding to the above-mentioned second information. That is, the center position of the second time domain resource is the center position of the first time domain resource, and the time domain resources actually occupied by the PUSCH can be extended to both ends based on the center position of the time domain resource indicated by the second information. In this embodiment, optionally, if the number of time domain resource units included in the second time domain resource is even, the even-numbered time domain resource unit of the center of the second time domain resource is determined as the center position, or the odd-numbered time domain resource unit of the center of the second time domain resource is determined as the center position.

[0272] Step S2105: The network device 101 sends the third information.

[0273] In some embodiments, the terminal 102 receives third information sent by the network device 101 .

[0274] In some embodiments, the third information is used to indicate a modulation and coding strategy MCS corresponding to the PUSCH sent by the terminal 102 .

[0275] In each embodiment of the present application, the PUSCH sent by the terminal 102 is sent based on orthogonal cover code OCC multi-user multiplexing, that is, the terminal 102 is a user using OCC multiplexing.

[0276] In some embodiments, the third information is used to indicate a first coding rate, and the terminal 102 can determine a second coding rate based on the first coding rate and the third parameter. Furthermore, the terminal 102 can determine a transport block size TBS corresponding to the transmitted PUSCH based on the second coding rate.

[0277] In some embodiments, the third information is used to indicate a second coding rate, and the terminal 102 can determine the transport block size TBS corresponding to the transmitted PUSCH based on the second coding rate. The base station determines the transport block size TBS corresponding to the received PUSCH based on the second coding rate.

[0278] In some embodiments, the name of the third information is not limited, and it can be, for example, "downlink control information", "MCS", "MCS indication", "MCS index", etc.

[0279] In step S2106, the terminal 102 determines the modulation and coding strategy MCS of the PUSCH.

[0280] In the embodiment of the present application, the MCS includes a second coding rate corresponding to the PUSCH sent by the terminal 102 .

[0281] Furthermore, the terminal 102 can calculate the TBS based on the determined second coding rate.

[0282] In some embodiments, the third information indicates a first coding rate, and terminal 102 can determine the second coding rate based on the first coding rate and a third parameter. In this approach, the second coding rate is the ratio of the first coding rate to the third parameter, that is, the first coding rate is the product of the second coding rate and the third parameter. The second coding rate (actual bit rate) = the first coding rate (nominal bit rate) / the third parameter.

[0283] In some embodiments, the third information is used to indicate a second coding rate. In this approach, the second coding rate is a nominal coding rate, which is greater than an actual coding rate when the PUSCH is multiplexed using an OCC extension scheme.

[0284] In some embodiments, the third parameter is determined based on fourth information, and the fourth information includes at least one of the following:

[0285] The length of the OCC;

[0286] The number of OCC sequences;

[0287] Number of users multiplexed by OCC;

[0288] Maximum number of users that can be multiplexed by OCC.

[0289] In some embodiments, the length of the OCC, the number of OCC sequences, the number of users multiplexed by the OCC, and the maximum number of users multiplexed by the OCC are the same.

[0290] In some embodiments, the protocol may stipulate that the maximum modulation order expected by users (such as terminal 102) using OCC multiplexing is no more than 2, that is, only pi / 2 binary phase shift keying (BPSK) (pi / 2-BPSK) or quadrature phase shift keying (QPSK) modulation is supported.

[0291] In some embodiments, the value of the third parameter may be the same as or different from the value of the first parameter.

[0292] In some embodiments, the value of the third parameter may be the same as or different from the value of the second parameter.

[0293] In some embodiments, the first parameter M, the second parameter N, and the third parameter K may all be the same, or may all be different, or two of them may be the same and different from the other.

[0294] In some embodiments, the first parameter M, the second parameter N, and the third parameter K need to satisfy the following: the ratio of the product of the first parameter M and the second parameter N to the third parameter K is the length L of the OCC. That is, M*N*K=L, where M, N, and K are all positive integers.

[0295] In some embodiments, at least one of M, N, K, and L is indicated by the network device 101 or specified by a protocol.

[0296] In some embodiments, the parameter value of any one or two of M, N, and K is 1, indicating that the corresponding determination method is that the information received by the terminal 102 directly indicates the actual transmission parameters of the PUSCH.

[0297] In step S2107 , the network device 101 and the terminal 102 determine a transport block size TBS for sending the corresponding bearer of the PUSCH.

[0298] In some embodiments, the network device 101 and the terminal 102 determine the transport block size TBS for sending the PUSCH corresponding bearer based on at least one of the following information:

[0299] the first time domain resource mentioned above;

[0300] the second frequency domain resources mentioned above;

[0301] Demodulation Reference Signal (DMRS) resource overhead;

[0302] Resource overhead occupied by other signals or channels;

[0303] Modulation order;

[0304] the second coding rate mentioned above;

[0305] The length of the above OCC (or resource reuse factor).

[0306] In some embodiments, the terminal 102 determines the transport block size TBS for sending the PUSCH corresponding to the bearer based on at least one of the following information:

[0307] the second time domain resource mentioned above;

[0308] the first frequency domain resource mentioned above;

[0309] Resource overhead occupied by the demodulation reference signal;

[0310] Resource overhead occupied by other signals or channels;

[0311] Modulation order;

[0312] the second coding rate mentioned above;

[0313] The length of the above OCC (or resource reuse factor).

[0314] In some embodiments, the terminal 102 determines the transport block size TBS for sending the PUSCH corresponding to the bearer based on at least one of the following information:

[0315] the second time domain resource mentioned above;

[0316] the second frequency domain resources mentioned above;

[0317] Resource overhead occupied by the demodulation reference signal;

[0318] Resource overhead occupied by other signals or channels;

[0319] Modulation order;

[0320] the second coding rate mentioned above;

[0321] The length of the above OCC (or resource reuse factor).

[0322] As an example, the terminal 102 may determine the intermediate information bits used to calculate the TBS in the following manner: the terminal 102 first calculates the number of available REs in a PRB, and further determines the unquantized intermediate information bits using the following formula: N info =N RE ·R·Q m ·v / L. Where, N info is the number of intermediate information bits, N RE is the number of REs available in a PRB, R is the coding rate indicated by the network device (wherein R can be the first coding rate or the second coding rate. If the first parameter M=1, the second parameter N=1, and the third parameter K=OCC code length L, then R is the first coding rate in the embodiment of the present disclosure; if the third parameter K=1, then R is the second coding rate in the embodiment of the present disclosure), Q m is the modulation order, v is the number of transmission layers, and L is the OCC code length.

[0323] In some embodiments, the network device 101 may also calculate the TBS of the PUSCH corresponding bearer in the same manner as the terminal 102 .

[0324] In step S2108, the terminal 102 determines the number of coded bits carried by the PUSCH transmission.

[0325] In some embodiments, the terminal 102 determines the number of coded bits carried by the PUSCH based on the first time domain resource corresponding to the PUSCH, the first frequency domain resource corresponding to the PUSCH, the modulation order corresponding to the PUSCH, and the fourth information.

[0326] It can be understood that the above-mentioned number of coded bits is the output bits after rate-matching.

[0327] In some embodiments, G is the total number of coded bits available for transmission corresponding to a transport block TB, which should be determined according to the OCC length L.

[0328] In some embodiments, G may be determined based on the following method: total resources transmitted by PUSCH*modulation order / L.

[0329] In step S2109, the terminal 102 sends a PUSCH.

[0330] In some embodiments, the network device 101 receives the PUSCH.

[0331] In some embodiments, after the terminal 102 determines the frequency domain resources (first frequency domain resources) of the PUSCH, determines the time domain resources (first time domain resources) of the PUSCH, determines the MCS, coding rate (second coding rate), TBS, and number of coding bits corresponding to the PUSCH, it can send the PUSCH to the network device 101 based on the above parameters.

[0332] In some embodiments, an orthogonal cover code (OCC) is used for the PUSCH.

[0333] In some embodiments, terminal 102 is a user in an OCC multi-user multiplexing.

[0334] In some embodiments, the PUSCH is multi-user multiplexed based on orthogonal cover codes (OCC).

[0421] In some embodiments, the above method may include the above method of embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0422] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0423] The following is an exemplary introduction to the above methods in the above embodiments.

[0424] For users using OCC multiplexing, consider determining frequency domain resources based on at least one of the following methods:

[0425] In some embodiments (method 1), the number of REs / RBs / subPRBs determined based on the FDRA domain is the number of frequency domain resources used to generate the actual TBS and to carry modulation symbols before extension.

[0426] In this manner, the number of frequency domain resources actually occupied by PUSCH transmission will be expanded by M (first parameter) times in the frequency domain.

[0427] Optionally, the following different methods can be used to perform M-fold expansion in the frequency domain:

[0428] Reverse expansion based on start RB;

[0429] Back-to-back expansion based on end RB;

[0430] The frequency domain center position determined by RIV is the frequency domain center position of actual PUSCH transmission, and is extended toward both ends with the frequency domain center position as the center.

[0431] In some embodiments (method 2), the number of REs / RBs / subPRBs determined based on the FDRA field is the total number of resources used for carrying resource extension or symbol-extended transmission.

[0432] For users using OCC multiplexing, consider determining time domain resources based on at least one of the following methods:

[0433] In some embodiments (method 1), the number of symbols determined based on the TDRA field is the number of time domain resources used to actually generate the TBS and carry the modulation symbols before extension.

[0434] In this manner, the time domain resources actually occupied by the PUSCH transmission will be expanded N (the second parameter) times in the time domain.

[0435] Optionally, N-fold expansion can be performed in the time domain in the following different ways:

[0436] Reverse expansion based on the start symbol position;

[0437] Back-to-back expansion based on the end symbol position;

[0438] The symbol center position determined by SLIV is the symbol center point of actual PUSCH transmission, and symbol extension is performed toward both ends based on this center point.

[0439] Specifically, the symbol center position determined by SLIV is the symbol center point of the actual PUSCH transmission, and based on this center point, the symbol is extended to both ends. If the number of symbols is even, the even symbol or odd symbol at the center position is defined as the center point.

[0440] In some embodiments (method 2), the number of OSs determined based on the TDRA field is the total number of OSs used for transmission after carrying resource extension or symbol extension.

[0441] For users using OCC multiplexing, consider determining the MCS based on the following methods:

[0442] In some embodiments (method 1), the code rate indicated by the MCS index is a nominal code rate, and the actual code rate is further determined based on the following method: actual code rate = nominal code rate / K.

[0443] Optionally, the terminal performs TBS calculation based on the actual bit rate.

[0444] In some embodiments (method 2), the code rate indicated by the MCS index is the actual code rate.

[0445] Optionally, the protocol stipulates that for users using OCC multiplexing, the maximum modulation order expected by them is no more than 2, that is, only pi / 2-BPSK or QPSK is supported.

[0446] In some embodiments, based on the above embodiments, the following considerations are made: M*N / K=L, where M, N and K should be integers greater than 0, and at least two of M, N, and K are indicated by the base station or specified by the protocol. If the value of any one of the parameters is 1, it indicates that the corresponding method adopts method 2.

[0447] In some embodiments, based on the above embodiments, the terminal side and the network device side calculate the TBS based on at least one of the following factors:

[0448] The number of time domain symbols allocated by TDRA, the number of frequency domain RBs or the total number of REs, the resource overhead occupied by DMRS, the overhead occupied by other signals / channels (---xoverhead), the modulation order, the code rate R, and the OCC code length (or resource reuse factor).

[0449] In a possible embodiment, a user performing OCC multiplexing determines intermediate information bits used for calculating the TBS in the following manner:

[0450] Step 1: The terminal first calculates the number of REs available in a PRB.

[0451] Step 2: Further, determine the total number of available REs using the following formula.

[0452] Step 3: Further, the terminal determines the unquantized intermediate information bits using the following formula.

[0453] N info =N RE ·R·Q m ·v / L. Where, N info is the number of intermediate information bits, N RE is the number of REs available in a PRB, R is the actual coding rate of PUSCH (that is, the second coding rate in the embodiment of the present disclosure), N RE R is the total number of available REs, Q m is the modulation order, v is the number of transmission layers, and L is the OCC code length.

[0454] In some embodiments, for users adopting OCC multiplexing, the determination of rate-matching output bits is considered based on the following factors: G is the total number of coded bits available for transmission of a transport block TB, which should be determined according to the OCC length L.

[0455] Optionally, G may be determined based on: total resources for PUSCH transmission*modulation order / L.

[0456] It is conceivable that if the factors determined in the second method in the above embodiments and the R16 (legacy) protocol are used to calculate the TBS, the actual code rate will be increased by approximately L times.

[0457] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.

In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions.

Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits.

All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by 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 implementing the hardware circuit configuration 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. In addition, 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), a deep learning processing unit (DPU), etc.
