[0116] The terms and concepts involved in the embodiments of this disclosure are described below.

[0117] I. DSA Technology

[0118] During the uplink packet transmission process, the terminal copies the uplink packet to generate one or more duplicate packets, and then transmits the uplink packet and duplicate packets in multiple random time slots. The network device's receipt of any one of these packets indicates successful reception, thus reducing the probability of collision failures and increasing the probability of successful uplink packet transmission.

[0119] II. Contention Resolution Diversity Slotted ALOHA (CRDSA) Techniques

[0120] Figure 1B is a schematic diagram of different terminals sending multiple data packets and their copies. As shown in Figure 1B, terminal A sends data packet 2 and its copy in time slots 1 and 4 respectively, i.e., packet 2 in the figure; and data packet 4 and its copy in time slots 6 and 8 respectively, i.e., packet 4 in the figure. Terminal B sends data packet 1 and its copy in time slots 1 and 9 respectively, i.e., packet 1 in the figure; sends data packet 3 and its copy in time slots 4 and 5 respectively, i.e., packet 3 in the figure; and sends data packet 5 and its copy in time slots 6 and 8 respectively, i.e., packet 5 in the figure. Terminal C sends data packet 6 and its copy in time slots 6 and 9 respectively, i.e., packet 6 in the figure.

[0121] As shown in Figure 1B, only one packet 3 exists in time slot 5; multiple packets collide in other time slots. Therefore, packet 3 can be correctly received and decoded. Based on packet 3 obtained in time slot 5, we know that another packet 3 is in time slot 4. Therefore, we can use packet 3 from time slot 5 to eliminate the interference from packet 3 in time slot 4, obtaining packet 2 from time slot 4. Using packet 2 from time slot 4, we can eliminate the interference from packet 2 in time slot 1, obtaining packet 1 from time slot 1, and so on, until packet 6 is obtained. However, packets 4 and 5 cannot be decoded due to unresolved contention.

[0122] The process described above is how the receiving end improves the packet reception success rate when transmission contention occurs by using serial interference cancellation technology.

[0123] In some embodiments, the copy package may also be replaced by terms such as "copy", "data copy", "transfer copy", etc.

[0124] In some embodiments, for DSA and CRDSA technologies, increasing the number of replicas means that a terminal consumes more transmission resources to transmit a single data packet and increases interference with other terminals sending data packets. However, at the same time, the success rate of data packet reception can also be improved. Therefore, determining the number of data replicas to balance transmission resource utilization and transmission reliability is a pressing issue that needs to be addressed.

[0125] In some embodiments, taking CRDSA technology as an example, network devices currently configure a CRDSA parameter for each terminal. This CRDSA parameter indicates the number of copies used for transmission. The terminal uses this single CRDSA parameter for all data transmission, meaning it sends the same number of copies for all data. For data with low reliability requirements, using more copies wastes resources and increases transmission contention. Conversely, for data with high reliability requirements, using fewer copies may fail to meet those requirements. Therefore, determining the number of copies for different types of data to balance transmission resource utilization and transmission reliability is a pressing issue.

[0126] This disclosure provides a communication method, communication device, communication system, storage medium, and program product. A terminal receives first information indicating configuration information for a transmission object. The configuration information includes transmission parameters used to determine the number of data copies of the transmission object. The terminal sends a first transmission block and copies of the first transmission block according to the first information. The first transmission block includes data from multiple transmission objects. Thus, on the one hand, configuring corresponding transmission parameters for specific transmission objects allows the terminal to determine the number of copies at a finer granularity. On the other hand, the terminal can determine the number of copies of the first transmission block based on the transmission parameters configured for each transmission object by the network device. This allows the transmission of the transmission block to effectively balance transmission resource utilization and transmission reliability, improving the data transmission performance of the communication system.

The communication method involved in the embodiments of the present disclosure can be applied to terminals, network devices, and terminals in the communication system 100. As shown in Figure 3, the communication method of the embodiments of the present disclosure includes steps S3101 to S3102.

[0296] In step S3101, the network device sends the first information.

[0297] Optional implementations of step S3101 can also be found in optional implementations of step S2101 in Figure 2A and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.

[0298] In step S3102, the terminal sends the first TB and a TB copy of the first TB according to the first information.

[0299] The optional implementation of step S3102 can also be found in the optional implementation of step S2104 in Figure 2A, and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.

[0300] In some embodiments, the first information includes configuration information of the transmission object, the configuration information including transmission parameters, and the transmission parameters are used to determine the number of data copies of the transmission object.

[0301] In some embodiments, the transport object includes at least one of the following: DRB, SRB, RLC bearer, LCH, QoS stream, MAC CE.

[0302] In some embodiments, the transmission parameters include at least one of the following: a first parameter indicating the number of data copies of the transmission object; a second parameter indicating the maximum number of data copies of the transmission object; and a third parameter indicating the range of the number of data copies of the transmission object.

[0303] In some embodiments, the first TB includes data from multiple transport objects. The number of TB copies of the first TB is determined based on the number of data copies of the multiple transport objects.

[0304] In some embodiments, the number of TB replicas of the first TB is the maximum number of data replicas of multiple transport objects within the first TB.

[0305] The communication method involved in the embodiments of this disclosure may include at least one of steps S3101 to S3102. For example, step S3101 may be implemented as a standalone embodiment. For example, step S3102 may be implemented as a standalone embodiment.

[0306] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0307] In some embodiments, for CRDSA technology, when the number of transmission copies increases, the terminal consumes more network resources (e.g., time domain transmission opportunities) to transmit a packet and increases interference to other terminals sending packets. At the same time, the success rate of receiving packets by the terminal can be improved.

[0308] In some embodiments, if the terminal currently has many services to be transmitted (e.g., some services have high requirements for transmission reliability, while others have low requirements for transmission reliability), using more transmission copies will waste resources and increase transmission competition for services with low requirements for transmission reliability, while using fewer transmission copies may not meet the required reliability for services with high requirements for transmission reliability.

[0309] In some embodiments, this disclosure proposes a method for configuring and using CRDSA based on service characteristics. By introducing DRB-based CRDSA transmission parameters configured in the network and determining CRDSA transmission parameters on the terminal side based on multi-service configuration, the use of CRDSA technology in NTN networks can balance the requirements of transmission resource utilization and service reliability.

[0310] In some embodiments, the network configures CRDSA transmission parameters for the DRB / SRB / RLC bearer / logical channel.

[0311] In some embodiments, the UE receives configuration information (e.g., RRC configuration) sent by the base station, wherein CRDSA transmission parameters related to replica transmission are configured for one or more transmission objects.

[0312] In some embodiments, the transmission object can be one of the following: DRB, SRB, RLC bearer, logical channel, or QoS flow. Specifically, the CRDSA transmission parameters are indicated in the configuration corresponding to the transmission object.

[0313] In some embodiments, the CRDSA transport parameters associated with replica transport can be one of the following:

[0314] (1) The number of replica transmissions actually used by the UE (i.e., the network specifies a certain number of replica transmissions).

[0315] (2) The maximum number of replica transmissions allowed for the UE (the UE randomly selects a value between 1 or 2 and the maximum value as the actual number of replica transmissions used).

[0316] (3) The range of the number of replica transmissions allowed for the UE (e.g., the range is [N1, N2], and the UE randomly selects a value between N1 and N2 as the actual number of replica transmissions used).

[0317] In one example, the network device configures CRDSA transmission parameters related to DRB copy transmission for DRB, and the CRDSA transmission parameters of DRB include at least one of the following: (1) the number of DRB data copies actually transmitted by the UE; (2) the maximum number of DRB data copies allowed for the UE to use; and (3) the range of the number of DRB data copies allowed for the UE to use.

[0318] In one example, the network device configures CRDSA transmission parameters related to SRB copy transmission for SRB, and the CRDSA transmission parameters of SRB include at least one of the following: (1) the number of SRB data copies actually transmitted by the UE; (2) the maximum number of SRB data copies allowed for the UE to use; and (3) the range of the number of SRB data copies allowed for the UE to use.

[0319] In one example, the network device configures CRDSA transmission parameters related to the transmission of copies of the RLC bearer. The CRDSA transmission parameters of the RLC bearer include at least one of the following: (1) the number of data copies of the RLC bearer actually used by the UE for transmission; (2) the maximum number of data copies of the RLC bearer that the UE is allowed to use; and (3) the range of the number of data copies of the RLC bearer that the UE is allowed to use.

[0320] In one example, the network device configures CRDSA transmission parameters related to LCH replication for LCH, and the CRDSA transmission parameters of the SRB include at least one of the following: (1) the number of LCH data replicas actually transmitted by the UE; (2) the maximum number of LCH data replicas allowed for the UE; and (3) the range of the number of LCH data replicas allowed for the UE.

[0321] In one example, the network device configures CRDSA transmission parameters related to the copy transmission for the MAC CE. The CRDSA transmission parameters of the MAC CE include at least one of the following: (1) the number of data copies of the MAC CE actually transmitted by the UE; (2) the maximum number of data copies of the MAC CE that the UE is allowed to use; and (3) the range of the number of data copies of the MAC CE that the UE is allowed to use.

[0322] In some embodiments, the network additionally configures whether these transport objects can use CRDSA resources. If not configured, it can be assumed by default that the transport object can or cannot use CRDSA resources.

[0323] In some embodiments, if the CRDSA transport parameters associated with the replica transport are not configured for a transport object network that allows the use of CRDSA resources, the terminal considers...

[0324] Option 1: This transfer object has no limit on the number of replicas that can be transferred, meaning that any number of replicas can be transferred as permitted by the network (e.g., values ​​configured for other transfer objects).

[0325] Option 2: The number of copies of the transmitted object is the maximum allowed by the network.

[0326] In one example, if the DRB data is allowed to use CRDSA resources, but the network device has not configured CRDSA transmission parameters for the DRB, but has configured CRDSA transmission parameters for both the SRB and LCH, then the terminal can use the LCH CRDSA transmission parameters to determine the number of DRB data replicas, or the terminal can use the SRB CRDSA transmission parameters to determine the number of DRB data replicas. That is, Scheme 1 is used to determine the number of DRB data replicas.

[0327] In one example, if LCH data is allowed to use CRDSA resources, but the network device has not configured the LCH CRDSA transmission parameters, but instead configured the maximum number of transmission replicas available to all transmission objects for the terminal, then the terminal can use the maximum number of replicas configured by the network device for the terminal to determine the number of LCH data replicas. This is where Scheme 2 comes in.

[0328] In one example, if TB includes DRB data, SRB data, and MAC CE data, but the network device has not configured CRDSA transmission parameters for DRB and SRB, but has configured CRDSA transmission parameters for MAC CE, then the terminal can use the MAC CE transmission parameters to determine the number of SRB data replicas and use the maximum number of replicas configured by the network device for the terminal to determine the number of DRB data replicas. That is, Scheme 1 and Scheme 2 can be used in combination.

[0329] In some embodiments, taking DRB as an example, for DRBs with high transmission reliability requirements, the network is configured with a larger number of replica transmissions. For DRBs with low transmission reliability requirements, the network is configured with a smaller number of replica transmissions.

[0330] In some embodiments, for SRB, the network is configured with a large number of replica transfers.

[0331] In some embodiments, the network configures CRDSA transmission parameters for the MAC CE.

[0332] In some embodiments, the network configures CRDSA transmission parameters related to replica transmission for all or some uplink MAC CEs (the specific CRDSA transmission parameters are the same as those in the embodiments described above).

[0333] In some embodiments, if the configuration is for a subset of MAC CEs, the network may indicate the logical channel ID of these MAC CEs. Optionally, the network may additionally configure whether these MAC CEs can use CRDSA resources. If not configured, it may be assumed by default that the MAC CE can or cannot use CRDSA resources.

[0334] In some embodiments, the UE considers the CRDSA transmission parameter information of each logical channel during transmission.

[0335] In some embodiments, when using CRDSA resources for uplink transmission, the terminal selects those transmission objects that are allowed to use CRDSA resources for packetization, and the terminal determines the number of replica transmissions it uses based on the CRDSA transmission parameters of the service to be transmitted or the transmission objects multiplexed into a packet.

[0336] In some embodiments, for a scenario where multiple transport objects are multiplexed into a transport block TB, the terminal selects the maximum value from the number of replicas transmitted for the multiple transport objects as the final number of replicas used to transmit the TB.

[0337] In some embodiments, the above embodiments use CRDSA technology as an example, but are equally applicable to DSA technology.

[0338] This disclosure also proposes an apparatus for implementing any of the above methods. For example, a terminal is proposed, which includes units or modules for implementing the steps performed by the terminal in any of the above methods.

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. In addition, it can also be hardware circuits designed for artificial intelligence, which can be understood as ASICs, such as Neural Network Processing Units (NPUs), Tensor Processing Units (TPUs), and Deep Learning Processing Units (DPUs).
