[0112] As shown in Figure 1A, the communication system 100 includes a terminal 101 and a network device 102.

The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0118] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0119] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0120] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0121] 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 communication 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).

[0122] In the field of communication technology, Contention Resolution Diversity Slotted ALOHA (CRDSA) is a technique that reduces the probability of uplink collisions and improves uplink capacity by reducing contention in a channel. The terminal replicates the uplink transmission to generate multiple uplink transmissions, which are then sent at different times. The network successfully receives any one of these uplink transmissions, thus reducing the probability of collision failures.

[0123] In some embodiments, because terminals sending at least two identical uplink transmissions increases the probability of collisions, interference cancellation techniques are required. The process is illustrated below with reference to Figure 1B. Figure 1B is a timing diagram of uplink transmissions received by a network device. For example, a terminal sends two uplink transmissions PK3. One PK3 transmission does not collide and can be correctly parsed by the network device. The other PK3 transmission collides with an uplink transmission PK2 sent by another terminal. The network device can then use the correctly parsed PK3 to perform interference cancellation on the other PK3 transmission, allowing it to correctly parse the uplink transmission PK2 sent by the other terminal. The network device can then use the parsed PK2 to perform interference cancellation on the other PK2 transmission, parsing PK1, and so on, until all parseable uplink transmissions are parsed, such as PK4, PK5, and PK6 in the figure.

[0124] In some embodiments, the terminal can choose to configure resources, such as using configured grant (CG) resources to transmit multiple uplink transmissions. In this case, the terminal first needs to determine the CG resources to be used for transmitting the multiple uplink transmissions.

[0125] In addition, the terminal also needs to determine the process for sending multiple uplink transmissions using the Hybrid Automatic Repeat Request (HARQ) process.

[0126] Furthermore, in uplink transmissions using CG resources, the lack of a preamble presents a challenge in channel estimation, a problem this disclosure addresses. In high-speed mobile scenarios, the channel coherence time is very short, making channel estimation based on an uplink transmission sent at one time inaccurate, thus hindering interference cancellation. For CRDSA based on random access, uplink transmissions can be channel-estimated based on their accompanying preamble, rather than another uplink transmission. However, for uplink transmissions using CG resources, there is no accompanying preamble. Therefore, this disclosure proposes channel estimation based on a Demodulation Reference Signal (DMRS). Different UEs transmit the Physical Uplink Shared Channel (PUSCH) using different DMRS resources. This allows the network to identify the DMRS transmitted by different UEs at collision locations, enabling them to perform their respective channel estimations.

[0127] Furthermore, the terminal also needs to determine the DMRS resources used for multiple uplink transmissions.

[0128] The uplink transmission method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0129] Figure 2A is an interactive schematic diagram of an uplink transmission method according to an embodiment of the present disclosure. As shown in Figure 2A, the present disclosure relates to an uplink transmission method, which includes:

[0130] In step S2101, terminal 101 sends third information to network device 102.

[0131] In some embodiments, the third information is used to indicate whether the terminal supports sending multiple uplink transmissions.

[0132] In some embodiments, the third information may be used to indicate whether terminal 101 supports sending multiple uplink transmissions using configured resources.

[0133] In this embodiment of the disclosure, the terminal 101 indicates to the network device 102 whether it supports multiple uplink transmissions, thereby ensuring consistency in the understanding of the terminal's capabilities between the terminal and the network side, and providing conditions for reliable transmission of multiple uplink transmissions.

[0134] In some embodiments, network device 102 may configure resources for terminal 101 based on whether terminal 101 supports sending multiple online transmissions.

[0135] In some embodiments, network device 102 may receive third information sent by terminal 101.

[0136] In step S2102, terminal 101 determines multiple configuration resources.

[0137] In some embodiments, the terminal may be a non-terrestrial network (NTN) terminal or a terrestrial network (TN) terminal.

[0138] In some embodiments, the configuration resource may be a configured grant (CG) resource or a preconfigured uplink resource (PUR).

[0139] For example, the configuration resource can be a CG resource configured based on Radio Resource Control (RRC). Alternatively, it can be a CG resource activated based on Downlink Control Information (DCI). In other words, the configuration resource can be a ConfigurationGrantType 1 resource or a ConfigurationGrantType 2 resource.

[0140] In some embodiments, the configuration resource may also be other types of pre-configured resources.

[0141] In some embodiments, the ConfiguredGrant resource is a resource used in an inactive or connected state.

[0142] In some embodiments, the CG resources used in the inactive state may be, for example, CG resources used for small packet transmission, or CG resources configured for the connected state.

[0143] In some embodiments, the terminal can determine which resources to use to send multiple uplink transmissions based on the measurement results of CG resources and pre-configured uplink resources.

[0144] In this embodiment of the disclosure, the terminal can use configured authorized resources or pre-configured resources to send multiple uplink transmissions, which not only improves the flexibility of multiple uplink transmissions, but also provides conditions for increasing the success probability of multiple uplink transmissions.

[0145] In some embodiments, terminal 101 may randomly select multiple CG resources from the resource pool configured in network device 102.

[0146] In some embodiments, at least one of the time-domain, frequency-domain, and / or code-domain resources among the multiple CG resources selected by terminal 101 may be discontinuous.

[0147] In some embodiments, the code domain resource can be a demodulation reference signal (DMRS).

[0148] For example, multiple CG resources can be multiple CG resources that are not contiguous in the time domain, or they can be resources corresponding to different DMRS, etc. This disclosure does not limit them.

[0149] In some embodiments, the configuration resources can be shared by multiple terminals, or they can be configured specifically for a terminal by the network device; that is, the configuration resources can be per UE specific.

[0150] In some embodiments, multiple configuration resources may come from the same configuration resource configuration, or the multiple configuration resources may come from different configuration resource configurations. That is, the periods, start and end positions, etc., corresponding to multiple configuration resources may be the same or different.

[0151] In this embodiment of the disclosure, the terminal can send multiple uplink transmissions using configuration resources from the same or different configurations, which not only improves the flexibility of multiple uplink transmissions, but also increases the probability of multiple uplink transmissions being reliably received, thus improving the reliability of multiple uplink transmissions.

[0152] In some embodiments, the multiple configuration resources are dedicated configuration resources for multiple uplink transmissions, or the multiple configuration resources are general configuration resources for uplink transmissions. The content carried in the multiple uplink transmissions is the same.

[0153] In some embodiments, the terminal can use dedicated configuration resources to send multiple uplink transmissions, and the corresponding network device can receive multiple uplink transmissions sent by the terminal by simply listening to the dedicated configuration resources, thereby reducing the service burden of the network device in the CRDSA scenario.

[0154] In some embodiments, the terminal can send multiple uplink transmissions using a common configuration resource. The corresponding network device can receive multiple uplink transmissions sent by all terminals by only listening to the common configuration resource, which further reduces the service burden of the network device in the CRDSA scenario and improves the reliability and success rate of uplink transmission in the CRDSA scenario.

[0155] In other words, terminal 101 can select multiple configuration resources from multiple configured resource pools dedicated to carrying the same data uplink transmissions; or, terminal 101 can also select multiple configuration resources from a general configuration resource pool configured for uplink transmissions.

[0156] In some embodiments, network device 102 may configure configuration resources dedicated to multiple uplink transmissions for terminal 101 only when it is determined that the terminal supports sending multiple uplink transmissions using configuration resources. This avoids the waste of resources caused by network device 102 configuring corresponding resources for terminal 101 when terminal 101 does not support sending multiple uplink transmissions using configuration resources.

[0157] In some embodiments, the timing of the multiple configuration resources determined by terminal 101 may fall within a time period of a first time length.

[0158] In this embodiment of the disclosure, considering the possibility that different uplink transmissions may occur at different times, in order to ensure that the network device 102 can infer the relative phase offset of different uplink transmissions, the terminal 101 is required not to perform timing advance (TA) adjustment when sending multiple uplink transmissions; otherwise, phase continuity will be disrupted. If the terminal 101 does not perform TA adjustment, considering the movement of satellites, the TA deviation will gradually accumulate. To avoid the TA deviation accumulating to the upper limit that the network device can handle, when selecting multiple configuration resources, the terminal 101 can select multiple configuration resources to send multiple uplink transmissions within a time period of a first time length, so as to minimize the TA deviation accumulated by multiple uplink transmissions.

[0159] In some embodiments, terminal 101 may determine the first time length according to the protocol agreement.

[0160] In some embodiments, terminal 101 may also determine the first time length according to the instructions of network device 102.

[0161] In some embodiments, if the time domain locations of the multiple CG resources selected by terminal 101 are the same, but the frequency domain and / or code domain resources are different, then terminal 101 is required to send multiple uplink transmissions to the network device at the same time. To ensure that each uplink transmission can be reliably transmitted, terminal 101 needs to provide a large transmission power. In order to avoid this situation as much as possible, when terminal 101 selects multiple CG resources, it can select CG resources corresponding to different time domain timings. That is, it sends multiple uplink transmissions at multiple different time domain timings, thereby ensuring that each uplink transmission can be sent with a large transmission power. This improves the success probability of multiple uplink transmissions while avoiding the situation of excessive instantaneous power of the terminal.

[0162] In step S2103, terminal 101 uses the HARQ process associated with each configuration resource as the HARQ process for sending uplink transmissions using that configuration resource.

[0163] In some embodiments, terms such as "uplink transmission", "uplink send", "uplink copy packet", "uplink data packet", and "uplink packet" can be used interchangeably.

[0164] In some embodiments, the uplink transmission can be a Media Access Control (MAC) packet data unit (PDU) or a MAC service data unit (SDU).

[0165] In some embodiments, the number of copies of multiple uplink transmissions can be agreed upon by the system or configured by the network device. For example, the number of copies of multiple uplink transmissions can be indicated in the CG configuration or in the CG's scheduling DCI.

[0166] In some embodiments, each configuration resource may have multiple occasions. Terminal 101 may randomly select one of the multiple occasions as the occasion for sending uplink transmissions using the configuration resource, and associate the HARQ process with that occasion to determine the HARQ process for sending uplink transmissions.

[0167] For example, if terminal 101 has two uplink transmissions to send, and terminal 101 selects a corresponding CG resource for each uplink transmission, then terminal 101 can randomly select a time from the time slots of each CG resource, and determine the HARQ process associated with that time slot as the HARQ time slot for sending the corresponding uplink transmission using that CG resource.

[0168] In this embodiment of the present disclosure, the terminal 101 uses the HARQ process associated with the selected configuration resource as the HARQ process that sends uplink transmissions using the configuration resource. This enables the network device 102 to determine the HARQ process to be scheduled based on the configuration resource at the time of receiving the uplink transmission, thereby simplifying the complexity of HARQ process scheduling in the network device 102 and improving the efficiency of HARQ process scheduling.

[0169] In some embodiments, if the timing of multiple CG resources selected by terminal 101 is different, and there is a one-to-one mapping relationship between the HARQ process and the timing of resource configuration, then terminal 101 determines that the HARQ processes corresponding to different resource configuration timings may be the same or different. That is to say, the HARQ processes used by multiple uplink transmissions may be the same, not exactly the same, or completely different.

[0170] In some embodiments, terminal 101 may determine the HARQ process associated with the timing of resource configuration according to the protocol agreement.

[0171] In some embodiments, terminal 101 can determine the timing-related HARQ process for configuring resources based on the received first information, wherein the first information is sent by the network device.

[0172] In this embodiment of the disclosure, terminal 101 determines the association between configuration resources and HARQ processes according to the protocol agreement or the instructions of network devices, thereby ensuring the consistency of understanding between terminal 101 and network devices regarding the association between configuration resources and HARQ processes, and providing conditions for improving the reliability and accuracy of network devices in scheduling HARQ processes.

[0173] In some embodiments, terminal 101 may receive first information sent by network device 102.

[0174] In some embodiments, network device 102 may send first information to the terminal.

[0175] In some embodiments, the network device can configure only one HARQ process for all configuration resources, so that the terminal 101 always uses the same HARQ process to send each uplink transmission, thereby reducing the complexity of the network device in determining the HARQ process to be used for multiple uplink transmissions and improving the efficiency of the network device in performing channel interference cancellation.

[0176] In some embodiments, the network device can also configure multiple HARQ processes for multiple configuration resources, which can reduce HARQ blocking.

[0177] In step S2104, terminal 101 determines the DMRS corresponding to multiple uplink transmissions.

[0178] In some embodiments, terminal 101 may determine a DMRS corresponding to the plurality of uplink transmissions from the DMRS resource pool.

[0179] In other words, network device 102 can send multiple uplink transmissions based on a single DMRS. Upon receiving any uplink transmission, the network device can perform accurate channel estimation based solely on the DMRS associated with that single uplink transmission, determine the temporal location of other uplink transmissions, and thus accurately cancel interference between multiple uplink transmissions.

[0180] In some embodiments, terminal 101 can determine a DMRS corresponding to each uplink transmission from the DMRS resource pool.

[0181] In other words, terminal 101 can randomly select a DMRS associated with the current uplink transmission from the DMRS resource pool when sending each uplink transmission. Since different uplink transmissions use different DMRS, the probability of network device 102 accurately decoding the content carried in the uplink transmission is increased.

[0182] In some embodiments, the DMRS resource pool can be indicated to the terminal in the resource configuration. The DMRS resource pool configuration can include one or more of the following: the number of DMRS sequences (that is, the number of DMRS for Code Division Multiplexing (CDM), the number of DMRS for Frequency Division Multiplexing (FDM), and the number of DMRS ports. This improves the flexibility and diversity of DMRS resource configuration.

[0183] In some embodiments, terminal 101 may also identify the DMRS indicated by the second information as multiple DMRS corresponding to uplink transmissions. The second information is sent by network device 102.

[0184] In other words, network device 102 can configure a dedicated DMRS associated with multiple uplink transmissions for terminal 101. Then, terminal 101 can send multiple uplink transmissions based on the DMRS configured by network device 102. This eliminates the need for the terminal to synchronously transmit the associated DMRS when sending uplink transmissions, reducing the amount of transmission resources occupied by transmitting the DMRS.

[0185] In some embodiments, network device 102 may carry multiple uplink transport associated DMRSs in the configuration resource configuration, or carry the DMRS in the configuration resource activation DCI.

[0186] In some embodiments, network device 102 may send second information to terminal 101, wherein the second information is used to indicate to the terminal multiple uplink transmissions corresponding to DMRS.

[0187] In some embodiments, the order of steps S2104 and S2103 can be adjusted as needed. For example, S2104 can be executed first, followed by S2103; or S2103 and S2104 can be executed in parallel, etc. This disclosure does not limit this.

[0188] In some embodiments, the order of steps S2101 and S2102-S2104 can be adjusted as needed. For example, S2102-S2104 can be executed first, followed by S2101; or, any one of S2101 and S2102-S2104 can be executed in parallel, etc. This disclosure does not limit this.

[0189] In step S2105, terminal 101 uses the HARQ process associated with multiple configuration resources to send multiple uplink transmissions and / or DMRS to network device 102.

[0190] In some embodiments, terminal 101 may use the associated HARQ process to send corresponding uplink transmissions and / or DMRS to network device 102 at the appropriate time for each selected configuration resource.

[0191] In some embodiments, terminal 101 may send the corresponding DMRS to network device 102 at the same time as sending each uplink transmission.

[0192] In some embodiments, if each uplink transmission corresponds to a different DMRS, the terminal 101 can simultaneously send the multiple DMRS corresponding to each of the multiple uplink transmissions to the network device 102 when sending each of the multiple uplink transmissions. This allows the network device 102 to determine the DMRS corresponding to all other uplink transmissions with the same content after receiving any uplink transmission, thus ensuring that the network device can accurately identify the uplink transmission at the collision location and perform reliable interference cancellation.

[0193] In some embodiments, when sending each uplink transmission, terminal 101 may send only one DMRS corresponding to the current uplink transmission to the network device at the same time, thereby minimizing the amount of resources occupied by DMRS transmission.

[0194] In some embodiments, if the DMRS corresponding to each uplink transmission is the same, then terminal 101 may also transmit the corresponding DMRS only when sending a specified uplink transmission. By transmitting the DMRS only when sending a specified uplink transmission, the terminal reduces the amount of resources used for transmitting the DMRS while ensuring that the network device can perform reliable interference cancellation.

[0195] In some embodiments, if the DMRS selected by terminal 101 is indicated by network device 102 through the second information, then terminal 101 may not send DMRS when sending multiple uplink transmissions. After receiving an uplink transmission that does not contain DMRS, network device 102 can determine that the current uplink transmission is one of multiple uplink transmissions, and thus can perform channel estimation and interference cancellation based on the DMRS indicated by the second information. This ensures that network device 102 can perform reliable interference cancellation while simultaneously reducing the resource consumption of DMRS transmission.

[0196] In some embodiments, the protocol may specify which uplink transmission among multiple uplink transmissions is designated as a specific uplink transmission. For example, it may specify the first uplink transmission among multiple uplink transmissions as a specific uplink transmission, or the last uplink transmission among multiple uplink transmissions as a specific uplink transmission, etc. This disclosure does not limit this.

[0197] In some embodiments, terminal 101 may also determine a specific uplink transmission based on the instructions of network device 102.

[0198] In some embodiments, terminal 101 may carry the HARQ process identifier in the uplink control information (UCI) transmitted uplink.

[0199] In some embodiments, terminal 101 may use certain orthogonal frequency division multiplexing (OFDM) symbols on certain resource blocks (RBs) in the configuration resources for UCI transmission, such as using OFDM symbols that are not occupied by UCI.

[0200] In some embodiments, network device 102 can configure different resources for UCI transmission for different terminals 101, thus avoiding UCI collisions that could prevent resolution. In this way, even if one uplink transmission from a terminal collides with uplink transmissions from other terminals, the UCI can still be resolved. Then, the network device can use the HARQ Process ID obtained from a received uplink transmission to determine the HARQ Process used to receive other uplink transmissions.

[0201] In step S2106, network device 102 determines the DMRS corresponding to the first uplink transmission received.

[0202] In some embodiments, the first uplink transmission is at least one of a plurality of uplink transmissions.

[0203] In some embodiments, network device 102 can directly obtain the corresponding DMRS from the received uplink transmission.

[0204] In some embodiments, the DMRS obtained by the network device 102 from the received uplink transmissions can be one or more. That is, each uplink transmission in the multiple uplink transmissions can correspond to the same DMRS, or each uplink transmission in the multiple uplink transmissions can correspond to a separate DMRS.

[0205] In some embodiments, if the uplink transmission received by network device 102 does not contain DMRS, network device 102 can determine that the uplink transmission is one of a plurality of uplink transmissions, thereby determining the DMRS configured in the second information as the DMRS corresponding to the first uplink transmission.

[0206] In step S2107, network device 102 determines the time domain location corresponding to the second uplink transmission based on DMRS.

[0207] The second uplink transmission carries the same data as the first uplink transmission.

[0208] In some embodiments, network device 102 can determine the time domain location of receiving the DMRS as the delay location corresponding to the second uplink transmission.

[0209] In some embodiments, if the DMRS corresponding to the first uplink transmission is configured by the network device 102 to be associated with multiple uplink transmissions, then the network device 102 can determine the time domain position where no DMRS is received as the delay position corresponding to the second uplink transmission.

[0210] In some embodiments, the first uplink transmission and the second uplink transmission are transmitted using different configured resources.

[0211] In some embodiments, different configuration resources may be associated with the same or different HARQ processes.

[0212] In step S2108, network device 102 performs interference cancellation on third uplink transmission based on first uplink transmission. The third uplink transmission is received at the time domain position corresponding to the second uplink transmission.

[0213] Referring to Figure 1B above, if network device 102 receives uplink transmission PK3 sent by terminal 1 (as shown in the figure, PK3 that does not collide with other uplink transmissions), and network device 102 knows that terminal 1 sent two identical uplink transmissions PK3, then network device 102 can determine the time domain location of the other PK3 based on the DMRS corresponding to PK3. Then, based on the received PK3, network device 102 can perform interference cancellation on uplink transmissions received at the time domain location of the other PK3, thereby obtaining uplink transmission PK2 sent by terminal 2. Then, based on the DMRS corresponding to PK2, it can determine the time domain locations of other PK2s, and then perform interference cancellation on uplink transmissions received at other time domain locations based on the determined PK2s, and so on, thus accurately obtaining all uplink transmissions.

[0214] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2108. For example, step S2101 may be implemented as a standalone embodiment, steps S2102+S2105 may be implemented as a standalone embodiment, steps S2102+S2103+S2105 may be implemented as a standalone embodiment, steps S2106+S2107+S2108 may be implemented as a standalone embodiment, etc., but is not limited thereto.

[0215] 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.

[0216] Figure 2B is an interactive schematic diagram of an uplink transmission method according to an embodiment of the present disclosure. As shown in Figure 2B, the present disclosure relates to an uplink transmission method, which includes:

[0217] In step S2201, terminal 101 sends third information to network device 102.

[0218] In step S2202, terminal 101 determines multiple configuration resources.

[0219] The specific implementation of the above steps S2201-S2102 can be referred to the relevant parts of steps S2101-S2102 and optional implementations shown in Figure 2A of this disclosure, and will not be repeated here.

[0220] In step S2203, terminal 101 determines the timing of multiple uplink transmissions based on the same configuration resources of the associated HARQ process.

[0221] In some embodiments, after selecting multiple CG resources, the terminal can also determine the configuration resource time corresponding to the same HARQ process among the multiple CG resources as the transmission timing for multiple uplink transmissions. That is, the terminal 101 ultimately uses the same HARQ process to send multiple uplink transmissions carrying the same data to the network device 102 sequentially based on different configuration resource timings. This reduces the complexity of uplink interference cancellation performed by the network device 102.

[0222] For example, if terminal 101 wants to send two uplink transmissions carrying the same data, after selecting two configuration resources, the terminal can select two different configuration resource timings associated with the same HARQ process from the timings of the two configuration resources as the timings for sending the corresponding uplink transmissions, and determine the same HARQ process associated with the timings of the two configuration resources as the process used to send multiple uplink transmissions.

[0223] In step S2204, terminal 101 determines the DMRS corresponding to multiple uplink transmissions.

[0224] In step S2205, terminal 101 uses multiple HARQ processes associated with multiple transmission times to send multiple uplink transmissions and / or DMRS to network device 102 using multiple configuration resources.

[0225] In step S2206, network device 102 determines the DMRS corresponding to the first uplink transmission received.

[0226] In step S2207, network device 102 determines the time domain location corresponding to the second uplink transmission based on DMRS.

[0227] In step S2208, network device 102 performs interference cancellation on third uplink transmission based on first uplink transmission. The third uplink transmission is received at the time domain position corresponding to the second uplink transmission.

[0228] The specific implementation of steps S2203-S2208 can be referred to steps S2102-S2208 and the relevant parts of the optional implementation shown in Figure 2A of this disclosure, and will not be repeated here.

[0230] 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.

[0309] The uplink transmission method provided in this disclosure will be further described below with reference to the following embodiments.

[0310] When a terminal needs to send an uplink packet, it makes one or more copies of the uplink packet to obtain multiple copies, and uses configuration resources to send the multiple copies.

[0311] Optionally, the uplink packet and the packet obtained by copying the uplink packet are collectively referred to as a copied packet, or multiple uplink transmissions.

[0312] Optionally, the configuration resource can be a Configured Grant (such as a Configured Grant based on RRC configuration or a Configured Grant based on DCI activation, i.e., Configured Grant Type 1 and Configured Grant Type 2), or a preconfigured uplink resource (PUR), or other types of preconfigured resources.

[0313] Optionally, the Configured Grant resource is a resource used in inactive or connected states. CG resources used in inactive states include, for example, CG resources used for small packet transmission. Alternatively, they can be CG resources configured for connected states.

[0314] Optionally, the uplink packet is a MAC PDU or a MAC SDU.

[0315] Optionally, the number of copies of the package is determined by the system or configured by the network, such as indicated in the CG configuration or in the CG's scheduling DCI.

[0316] Optionally, the configuration resources are shared by multiple UEs.

[0317] Optionally, the terminal is an NTN terminal or a TN terminal, and the network is an NTN network or a TN network.

[0318] Optionally, the uplink configuration resources used to send multiple copy packets may come from the same configuration or may belong to different configurations.

[0319] Optionally, the configuration resource is a dedicated configuration resource specifically for sending the multiple replica packets, or a general configuration resource that can be used simultaneously for uplink transmissions that are not sent by the multiple replica packets.

[0320] Optionally, when the terminal uses configuration resources to send multiple replicated packets, it may use the same or different HARQ processes when sending each replicated packet.

[0321] Optionally, when sending each copy packet, the terminal uses the HARQ process associated with the selected configuration resource occasion as the HARQ process for sending the uplink packet.

[0322] Optionally, when sending each replication packet, the terminal selects the same configuration resource occasion as the associated HARQ process to send each replication packet.

[0323] Alternatively, if the terminal needs to send two copy packets, the terminal can select two different CG resource occasions in the time domain, and they are associated with the same HARQ process.

[0324] Optionally, the HARQ process associated with the configuration resource is configured by system convention or network device.

[0325] Optionally, the network device can configure only one HARQ process for the configuration resource, so that the terminal always uses this HARQ process to send each uplink packet. Alternatively, the network can configure multiple HARQ processes for the configuration resource, which can reduce HARQ congestion.

[0326] Optionally, when sending each copy packet, the terminal may randomly select the same number of configuration resources as the number of uplink packets within a time period T for sending.

[0327] Optionally, the time period T is determined by the system, configured by the network, or implemented by the terminal.

[0328] Optionally, when the terminal randomly selects configuration resources, it must ensure that the configuration resources used for sending each copy packet are located in different time domains.

[0329] Optionally, when the terminal sends each copy packet, the DM-RS used can be configured by the network in advance to the UE; the UE randomly selects one from the DM-RS resource pool, and then each copy packet uses the selected DM-RS; the UE randomly selects another DM-RS from the DM-RS resource pool each time it sends a copy packet, and uses that DM-RS for this copy packet transmission.

[0330] Optionally, the pre-configuration to the UE can be carried in the configuration resource configuration or in the configuration resource activation DCI.

[0331] Optionally, the DM-RS resource pool can be indicated to the UE in the resource configuration. The DM-RS resource pool configuration may include one or more of the following: the number of DM-RS sequences (i.e., the number of DM-RS in CDM), the number of DM-RS in FDM, and the number of DM-RS ports.

[0332] Optionally, the terminal reports capability information to the network, informing the network whether it supports the sending of multiple replicated packets based on configured resources.
