Description

Communication methods and apparatus, computer-readable storage media

[0001] This application claims priority to Chinese Patent Application No. 202411205267.4, filed on August 29, 2024, entitled "Communication Method and Apparatus, Computer-Readable Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method and apparatus, and a computer-readable storage medium. Background Technology

[0003] With the further evolution of communication technologies, the demand for system capacity in various communication scenarios (such as satellite communication) is becoming increasingly stringent, especially for enhancing uplink data transmission capacity. The most direct way to increase system capacity is to reduce the overhead of control information transmission resources. Network devices can configure shared, periodic uplink resources for data transmission through higher-layer signaling, and terminal devices can utilize these shared uplink resources for data transmission based on contention. However, since uplink resources are shared resources, resource conflicts can occur when multiple terminal devices select the same uplink resource for data transmission, leading to uplink data transmission failures.

[0004] One way to resolve uplink resource conflicts is for the terminal device to randomly select multiple uplink resources and send multiple copies when transmitting uplink data. In this way, even if one uplink data copy conflicts with the data transmission of other terminal devices, the other copies that do not conflict can be transmitted successfully.

[0005] However, in the multi-beam scenario of cellular communication systems, how terminal devices can use multiple common pre-configured uplink resources to send multiple uplink data copies is a technical problem that urgently needs to be solved. Summary of the Invention

[0070] The communication systems applicable to the embodiments of this application include, but are not limited to, Long Term Evolution (LTE) systems, 5th-generation (5G) systems, New Radio (NR) systems, and future evolution systems or multiple converged communication systems. The 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The technical solutions of this application are also applicable to different network architectures, including but not limited to relay network architectures, dual-connectivity architectures, and vehicle-to-everything (V2X) communication architectures.

[0071] This application primarily relates to communication between terminal devices and network devices. Specifically:

[0072] The network device in this application embodiment can also be called an access network device, for example, it can be a base station (BS) (also called a base station device). A network device is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in second-generation (2G) networks, the equipment providing base station functionality includes base transceiver stations (BTS); in third-generation (3G) networks, it includes nodes (NodeB); in fourth-generation (4G) networks, it includes evolved nodes (eNB); in wireless local area networks (WLANs), the equipment providing base station functionality is access points (APs); and in NR, the equipment providing base station functionality includes next-generation node base stations (gNBs) and further evolved nodes (ng-eNBs). gNBs and terminal devices communicate using NR technology, while ng-eNBs and terminal devices communicate using evolved universal terrestrial radio access (E-UTRA) technology. Both gNBs and ng-eNBs can connect to the 5G core network. The network devices in this application embodiment also include devices that provide base station functions in future new communication systems.

[0073] In this application, "terminal equipment" can refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication equipment, user agents, or user devices. Terminal equipment can also be cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal equipment in future 5G networks, or terminal equipment in future evolved Public Land Mobile Networks (PLMNs), etc. This application does not limit the scope of these terms. Terminal equipment can also be called user equipment (UE), terminal, etc.

[0074] As described in the background section, in the multi-beam scenario of cellular communication systems, how terminal devices can use multiple common pre-configured uplink resources to send multiple uplink data copies is a technical problem that urgently needs to be solved.

[0075] In the technical solution of this application, the terminal device sends M uplink data copies on M uplink resources within the uplink resource group associated with the same first SSB, thereby enabling the terminal device to send multiple uplink data copies with the same content using the same transmission beam, thereby improving communication efficiency.

[0076] Furthermore, to enable network devices to perform iterative interference cancellation between different terminal devices, each uplink data copy transmission requires the transmission of associated or included cross-reference information. This cross-reference information, associated or included in each uplink data copy transmission, indicates the uplink resource information where other uplink data copies reside. How the terminal devices send this cross-reference information is also a technical problem that urgently needs to be solved.

[0077] In addition, considering that after the terminal device finishes sending uplink data, it needs to receive a response message from the network device, how the terminal device receives the response message from the network device is also a technical problem that urgently needs to be solved.

[0078] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0079] The terminal device in this embodiment may or may not employ an uplink data copy transmission mechanism. When the terminal device does not employ an uplink data copy transmission mechanism, it selects an uplink resource to transmit uplink data. When the terminal device employs an uplink data copy transmission mechanism, it executes the steps shown in Figure 1.

[0080] Referring to Figure 1, the method provided in this application specifically includes the following steps:

[0081] Step 101: The terminal device sends M copies of uplink data on M uplink resources within the first uplink resource group. The first uplink resource group contains X uplink resources, and all uplink resources in the first uplink resource group are associated with the same first synchronization signal block (SSB).

[0082] In this embodiment, the association of the first SSB with the uplink resource indicates that when the terminal device uses the uplink resource to send uplink data, it can send uplink data according to the beam direction corresponding to the first SSB associated with the uplink resource.

[0083] In specific implementations, uplink resources may include one or more of the following: Physical Uplink Shared Channel (PUSCH) time-frequency resource blocks, Demodulation Reference Signal (DMRS) resources, orthogonal codes, etc. Among them, the PUSCH time-frequency resource block corresponds to the PUSCH Occasion (PO), which can also be called the uplink resource timing.

[0084] It should be noted that the number X of uplink resources included in the first uplink resource group can be configured by the network device or specified by the communication standard protocol, and this application does not impose any restrictions on this.

[0085] In practice, the terminal device uses one uplink resource to send one uplink data copy. The M data copies are copies of the same data, meaning that the content of the M data copies is identical.

[0086] In one specific implementation, the terminal device may randomly select M uplink resources from the X uplink resources in the first uplink resource group.

[0087] In another specific implementation, the terminal device can select M uplink resources from the X uplink resources in the first uplink resource group in a certain order.

[0088] For example, the terminal device selects M uplink resources in the first uplink resource group in ascending order of frequency resource index.

[0089] For example, the terminal device selects M uplink resources in the first uplink resource group according to the DMRS resource index in the uplink resources in ascending order.

[0090] For example, the terminal device selects M uplink resources in the first uplink resource group according to the time domain resource index of the uplink resources in ascending order.

[0091] For example, the terminal device selects M uplink resources in ascending order of their frequency domain resource indices in the first uplink resource group.

[0092] For example, the terminal device selects M uplink resources in ascending order of the index of the time slot where the uplink resources are located in the first uplink resource group.

[0093] For example, the terminal device selects M uplink resources in the first uplink resource group in ascending order of their periodic indices.

[0094] In this embodiment, since there is a one-to-one correspondence between SSBs and beams, all uplink resources in the first uplink resource group that are associated with the same first SSB mean that the terminal device uses the same beam to transmit uplink data when using the uplink resources in the first uplink resource group. Therefore, if the terminal device selects M uplink resources in the first uplink resource group to transmit M uplink data copies, it means that the M uplink data copies are transmitted using the same beam.

[0095] In this embodiment, network devices can configure common, periodic uplink resources for data transmission via higher-layer signaling. Each terminal device can utilize these common uplink resources for data transmission based on contention. Each terminal device groups uplink resources, classifying those associated with the same SSB into the same uplink resource group. When a terminal device needs to use common uplink resources for uplink data transmission, it determines a first SSB with signal quality greater than or equal to a preset threshold based on SSB measurement results. Then, it sends M uplink data copies on M uplink resources within the first uplink resource group associated with this first SSB. This allows the terminal device to send multiple data copies with the same content on the same beam, thereby improving communication efficiency.

[0096] For example, with M=2, the network device transmits SSB1 using beam 1 and SSB2 using beam 2. All uplink resources in uplink resource group 1 are associated with SSB1, and all uplink resources in uplink resource group 2 are associated with SSB2. The terminal device measures SSB1 and SSB2. If the signal quality of SSB1 is greater than a preset threshold, the terminal device determines SSB1 as the first SSB, and the uplink resource group 1 associated with SSB1 is the first uplink resource group. The terminal device selects two uplink resources (such as resource 1 and resource 2) in uplink resource group 1 and transmits two uplink data copies on resource 1 and resource 2 respectively using beam 1.

[0097] Furthermore, the first SSB can be associated with at least one uplink resource group, and the first uplink resource group is one of the at least one uplink resource groups. Specifically, when the first SSB is associated with multiple uplink resource groups, the terminal device can randomly select one of the multiple uplink resource groups as the first uplink resource group. Alternatively, the terminal device can select one of the multiple uplink resource groups in a certain order as the first uplink resource group. For example, the first uplink resource group can be selected according to the frequency resource index of the uplink resource, or according to the DMRS resource index within the uplink resource, etc., and this application does not impose any restrictions on this.

[0098] It should be noted that the sequence number of each step in this embodiment does not represent a limitation on the execution order of each step.

[0099] It is understood that, in specific implementations, the communication method can be implemented using a software program, which runs in a processor integrated within the chip or chip module. The method can also be implemented using a combination of software and hardware; this application does not impose any restrictions.

[0100] In this embodiment, the terminal device can group the uplink resources associated with the first SSB in different ways to obtain at least one uplink resource group associated with the first SSB. Specific embodiments will be described below.

[0101] Example 1: The terminal device divides the N uplink resources associated with the first SSB within the same first association period into Q uplink resource groups.

[0102] In this embodiment, the terminal device divides at least one uplink resource group into units based on a first association period, where the first association period is the association period between the SSB and the uplink resource.

[0103] Specifically, within the same first association period, there are N uplink resources associated with the first SSB. The terminal device divides these N uplink resources into Q uplink resource groups, each containing X uplink resources. The value of N can be determined using other parameters configured by the network device, such as the target mapping rate between the SSB and the uplink resources; the value of Q can be determined autonomously by the terminal device based on the values ​​of N and X.

[0104] For example, the uplink resources associated with the first SSB within the same first association period include uplink resources 1 to uplink resources 14. Each uplink resource group includes 7 uplink resources. Then the terminal device will divide uplink resources 1 to uplink resources 7 into uplink resource group 1 and uplink resources 8 to uplink resources 14 into uplink resource group 2.

[0105] Within a first association cycle, at least one round of mapping between SSB and uplink resources must be completed.

[0106] Furthermore, the terminal device can divide N uplink resources into Q uplink resource groups according to the order of the uplink resources.

[0107] The order of the N uplink resources can be obtained by sorting based on at least one of the following uplink resource index orders: frequency resource index of the uplink resource; demodulation reference signal (DMRS) resource index within the uplink resource; time domain resource index of the uplink resource; frequency domain resource index of the uplink resource; index of the time slot where the uplink resource is located; period index of the uplink resource.

[0108] For example, for N uplink resources associated with a first SSB, firstly, within an uplink resource time slot, the terminal device sorts the multiple uplink resources within the uplink resource time slot in ascending order according to the DMRS resource index of the uplink resources, and then sorts them in ascending order according to the period index number of the uplink resource time slot, thereby obtaining the order of the N uplink resources associated with the first SSB. Based on the order of the N uplink resources associated with the first SSB, the N uplink resources are divided into groups of X.

[0109] For example, X=4, N=8, the first SSB is associated with 8 uplink resources. Each uplink resource group includes 4 uplink resources, and a PO includes 4 DMRS resources, namely DMRS resource 0, DMRS resource 1, DMRS resource 2, and DMRS resource 3. The period index of PO1 is 1, and the period index of PO2 is 2. The terminal device sorts the multiple uplink resources in a PO in ascending order of DMRS resource index, resulting in the following DMRS resources in PO1: DMRS resource 0, DMRS resource 1, DMRS resource 2, and DMRS resource 3, and the following DMRS resources in PO2: DMRS resource 0, DMRS resource 1, DMRS resource 2, and DMRS resource 3. Then, they are sorted in ascending order of the PO's period index number, resulting in the following 8 DMRS resources: DMRS resource 0, DMRS resource 1, DMRS resource 2, and DMRS resource 3 in PO1, and DMRS resource 0, DMRS resource 1, DMRS resource 2, and DMRS resource 3 in PO2. The above 8 DMRS resources are divided into two uplink resource groups in sequence. Uplink resource group 1 includes DMRS resource 0, DMRS resource 1, DMRS resource 2 and DMRS resource 3 in PO1, and uplink resource group 2 includes DMRS resource 0, DMRS resource 1, DMRS resource 2 and DMRS resource 3 in PO2.

[0110] For example, for the N uplink resources associated with the first SSB, firstly, within an uplink resource time period, the terminal device sorts the multiple uplink resources within the uplink resource time period in ascending order according to the DMRS resource index of the uplink resources. Then, at least one PO that is time-domain multiplexed with the same SSB within the uplink resource period is sorted in ascending order according to the PO time domain resource index. Finally, it is sorted in ascending order according to the period index number of the uplink resource time period, thereby obtaining the order of the N uplink resources associated with the first SSB. Based on the order of the N uplink resources associated with the first SSB, the N uplink resources are divided into groups of X.

[0111] For example, for the N uplink resources associated with the first SSB, the terminal device sorts at least one PO that is time-domain multiplexed within a time slot in ascending order according to the PO time-domain resource index, thereby obtaining the order of the N uplink resources associated with the first SSB, and divides the N uplink resources into groups of X based on the order of the N uplink resources associated with the first SSB.

[0112] For example, for the N uplink resources associated with the first SSB, the terminal device sorts them in ascending order according to the time slot number of the PUSCH time-frequency resource block, thereby obtaining the order of the N uplink resources associated with the first SSB. Based on the order of the N uplink resources associated with the first SSB, the N uplink resources are divided into groups of X.

[0113] The DMRS resources are ordered in one of the following ways:

[0114] 1. First sort by DMRS port number in ascending order, then sort by DMRS sequence index number in ascending order;

[0115] 2. Sort in ascending order by the DMRS port index, then by the DMRS sequence index, and finally by the orthogonal code index;

[0116] 3. Sort in ascending order by DMRS sequence index, then by DMRS port index, and finally by orthogonal code index;

[0117] 4. Sort in ascending order by the orthogonal code index, then by the DMRS sequence index, and finally by the DMRS port index;

[0118] 5. Sort in ascending order by the orthogonal code index, then by the DMRS port index, and finally by the DMRS sequence index;

[0119] 6. Sort in ascending order by the DMRS port index, then by the orthogonal code index, and finally by the DMRS sequence index;

[0120] 7. Sort in ascending order according to the DMRS sequence index, orthogonal code index, and DMRS port index.

[0121] Figure 2 illustrates a specific application scenario. Here, X = 4, N = 8, meaning the first SSB is associated with 8 uplink resources, and each uplink resource group includes 4 uplink resources. As shown in Figure 2, within a first association period, the 8 uplink resources associated with SSB1 are located at the four frequency domain resource positions F1 to F4 of time domain resource position T1 and the four frequency domain resource positions F1 to F4 of time domain resource position T2. ​​The terminal device can then divide the 4 uplink resources located at the four frequency domain resource positions F1 to F4 of time domain resource position T1 into the first uplink resource group 1, and divide the 4 uplink resources located at the four frequency domain resource positions F1 to F4 of time domain resource position T2 into the second uplink resource group 2. Similarly, the eight uplink resources associated with SSB2 are located at the four frequency domain resource positions F1 to F4 of time domain resource position T3 and the four frequency domain resource positions F1 to F4 of time domain resource position T4. Therefore, the terminal device can group the four uplink resources located at the four frequency domain resource positions F1 to F4 of time domain resource position T3 into a third uplink resource group 3, and the four uplink resources located at the four frequency domain resource positions F1 to F4 of time domain resource position T4 into a fourth uplink resource group 4. The grouping method for the uplink resources associated with SSB3 and SSB4 is similar and will not be elaborated here.

[0122] Example 2: The terminal device divides the X uplink resources associated with the first SSB into an uplink resource group.

[0123] Compared to Example 1, this example no longer restricts whether the uplink resources associated with the first SSB are within the same first association period. That is, as long as the uplink resources are associated with the first SSB, every X uplink resources can be divided into an uplink resource group in a certain order.

[0124] In specific implementation, starting with the first system frame of the first associated period, that is, starting with System Frame Number (SFN) 0, X uplink resources are divided into an uplink resource group according to at least one of the following uplink resource index information: frequency resource index of uplink resources; demodulation reference signal (DMRS) resource index within uplink resources; time domain resource index of uplink resources; frequency domain resource index of uplink resources; index of the time slot where the uplink resources are located; period index of uplink resources.

[0125] For example, firstly, within an uplink resource opportunity, the terminal device sorts multiple uplink resources within the uplink resource opportunity in ascending order according to the DMRS resource index of the uplink resources, and then sorts them in ascending order according to the periodic index number of the uplink resource opportunity, thereby obtaining the order of the uplink resources associated with the first SSB. Based on the order of the uplink resources associated with the first SSB, the uplink resources associated with the first SSB are divided into groups of X.

[0126] For example, X=8, each SSB is associated with 8 uplink resources, and a PO includes 4 DMRS resources, namely DMRS resource 0, DMRS resource 1, DMRS resource 2, DMRS resource 3, DMRS resource 4, DMRS resource 5, DMRS resource 6, and DMRS resource 7. The period index of PO1 is 1, and the period index of PO2 is 2. The terminal device sorts the multiple uplink resources in a PO in ascending order of the DMRS resource index, resulting in the following DMRS resources in PO1: DMRS resource 0, DMRS resource 1, DMRS resource 2, DMRS resource 3, DMRS resource 4, DMRS resource 5, DMRS resource 6, and DMRS resource 7, and the following DMRS resources in PO2: DMRS resource 0, DMRS resource 1, DMRS resource 2, DMRS resource 3, DMRS resource 4, DMRS resource 5, DMRS resource 6, and DMRS resource 7. Then, sort them in ascending order according to the periodic index number of the PO, resulting in 16 DMRS resources: DMRS resource 0, DMRS resource 1, DMRS resource 2, DMRS resource 3, DMRS resource 4, DMRS resource 5, DMRS resource 6, and 7 in PO1, and DMRS resource 0, DMRS resource 1, DMRS resource 2, DMRS resource 3, DMRS resource 4, DMRS resource 5, DMRS resource 6, and 7 in PO2. These 16 DMRS resources are then sequentially divided into two uplink resource groups: Uplink resource group 1 includes DMRS resource 0, DMRS resource 1, DMRS resource 2, DMRS resource 3, DMRS resource 4, DMRS resource 5, DMRS resource 6, and 7 in PO1, and Uplink resource group 2 includes DMRS resource 0, DMRS resource 1, DMRS resource 2, DMRS resource 3, DMRS resource 4, DMRS resource 5, DMRS resource 6, and 7 in PO2.

[0127] For example, firstly, within an uplink resource timeframe, the terminal device sorts multiple uplink resources within the timeframe according to the ascending order of the DMRS resource index of the uplink resources. Then, it sorts at least one PO that is time-domain multiplexed with the same SSB within the uplink resource period according to the ascending order of the PO time-domain resource index. Finally, it sorts them according to the ascending order of the period index number of the uplink resource timeframe, thereby obtaining the order of the uplink resources associated with the first SSB. Based on the order of the uplink resources associated with the first SSB, the uplink resources associated with the first SSB are divided into groups of X.

[0128] For example, the terminal device sorts the PUSCH time-frequency resource blocks in ascending order according to the time slot number, thereby obtaining the order of the uplink resources associated with the first SSB. Based on the order of the uplink resources associated with the first SSB, the uplink resources associated with the first SSB are divided into groups of X.

[0129] Figure 3 illustrates a specific application scenario. In this scenario, each SSB associates two uplink resources in a first association cycle, and each uplink resource group comprises eight uplink resources. As shown in Figure 3, starting from SFN0, the eight uplink resources associated with SSB1 are divided into the first uplink resource group. These eight uplink resources are located at time-domain resource position T1 and frequency-domain resource positions F1 and F2, time-domain resource position T3 and frequency-domain resource positions F1 and F2, time-domain resource position T5 and frequency-domain resource positions F1 and F2, and time-domain resource position T7 and frequency-domain resource positions F1 and F2, respectively, which are the uplink resources shown with shaded fill in Figure 3. Similarly, starting with SFN0, the eight uplink resources associated with SSB2 are divided into a second uplink resource group. These eight uplink resources are located at time-domain resource position T1 and frequency-domain resource positions F3 and F4, time-domain resource position T3 and frequency-domain resource positions F3 and F4, time-domain resource position T5 and frequency-domain resource positions F3 and F4, and time-domain resource position T7 and frequency-domain resource positions F3 and F4, respectively. The grouping method for the uplink resources associated with SSB3 and SSB4 is similar and will not be described in detail here.

[0130] Example 3: The terminal device divides the uplink resources associated with the first SSB within the same second association period into an uplink resource group. The second association period includes at least one first association period.

[0131] Unlike Embodiment 1 described above, this embodiment divides uplink resources associated with the first SSB within the same second association period into an uplink resource group. The network device can pre-configure the second association period, which may include at least one first association period.

[0132] The number of first association cycles included in the second association cycle can be configured by the network device or specified by the communication standard protocol; this application does not impose any restrictions on this.

[0133] Figure 4 illustrates a specific application scenario. In this scenario, each SSB associates two uplink resources within a first association period, each second association period comprises four first association periods, and each uplink resource group includes eight uplink resources. As shown in Figure 4, within the same second association period, the eight uplink resources associated with SSB1 are divided into the first uplink resource group. These eight uplink resources are located at time-domain resource position T1 and frequency-domain resource positions F1 and F2, time-domain resource position T3 and frequency-domain resource positions F1 and F2, time-domain resource position T5 and frequency-domain resource positions F1 and F2, and time-domain resource position T7 and frequency-domain resource positions F1 and F2, respectively, as shown by the shaded uplink resources in Figure 4. Similarly, within the same second association period, the eight uplink resources associated with SSB2 are divided into a second uplink resource group. These eight uplink resources are located at time domain resource position T1 and frequency domain resource positions F3 and F4, time domain resource position T3 and frequency domain resource positions F3 and F4, time domain resource position T5 and frequency domain resource positions F3 and F4, and time domain resource position T7 and frequency domain resource positions F3 and F4, respectively. The grouping method for uplink resources associated with SSB3 and SSB4 is similar and will not be described in detail here.

[0134] In Embodiments 1, 2, and 3 above, the X uplink resources in the first uplink resource group can also be sorted according to at least one uplink resource index information. The uplink resource index information may include: a frequency resource index of the uplink resource, a demodulation reference signal (DMRS) resource index within the uplink resource, a time-domain resource index of the uplink resource, a frequency-domain resource index of the uplink resource, an index of the time slot where the uplink resource is located, and a period index of the uplink resource.

[0135] In practice, the above-mentioned at least one uplink resource index information can be combined in different orders to sort the X uplink resources in the first uplink resource group.

[0136] For example, the uplink resources are first sorted in ascending order of frequency resources; then, within a PUSCH time slot, the uplink resources are sorted in ascending order of DMRS resource index; then, within a time slot, the uplink resources are sorted in ascending order of time domain resource index; and finally, the uplink resources are sorted in ascending order of time slot index.

[0137] For example, the uplink resources are first sorted in ascending order of frequency resources; then, within a time slot, the uplink resources are sorted in ascending order of time domain resource index; then, the uplink resources are sorted in ascending order of time slot index; and finally, within a PUSCH time slot, the uplink resources are sorted in ascending order of DMRS resource index.

[0138] For example, the uplink resources are first sorted in ascending order of time domain resource index within a time slot, then sorted in ascending order of time slot index, then sorted in ascending order of frequency resource; finally, the uplink resources are sorted in ascending order of DMRS resource index within a PUSCH time slot.

[0139] It should be noted that the order of combining various uplink resource index information can be set according to the actual application scenario, and this application does not impose any restrictions on it.

[0140] Please refer to Figure 5, which illustrates the flow of another communication method.

[0141] In this embodiment, the terminal device can determine the receiving time window position and receive response messages corresponding to M uplink data copies within the time window, thereby achieving the reception of response messages at an appropriate time and improving communication reliability.

[0142] In step 501, the terminal device sends M copies of uplink data on M uplink resources within the first uplink resource group.

[0143] In step 502, the terminal device receives response messages corresponding to M uplink data copies within the receiving time window.

[0144] In this embodiment, the receiving time window position includes the time domain start position and the time domain end position of the receiving time window. The time domain start position of the receiving time window is determined based on the reference time position.

[0145] For example, the starting position of the receiving time window in the time domain can be equal to the reference time position.

[0146] For example, referring to Figure 6a, if the reference time position is time slot 2, then the starting position of the time domain of the receiving time window 1 is time slot 2.

[0147] For example, the starting position of the receiving time window in the time domain can be the time position after the reference time position, delayed by a preset time offset.

[0148] For example, referring to Figure 6a, the reference time position is time slot 2, the preset time offset is 3 time slots, and time slot 2 is delayed by 3 time slots to become time slot 5. Then the starting position of the time domain of the receiving time window 2 is time slot 5.

[0149] It should be noted that the unit of reference time position can also be a time slot, subframe, or other appropriate time unit, and this application does not impose any restrictions on this.

[0150] Specifically, the reference time location is one of the following:

[0151] The end position of the time domain of the last uplink resource in the M uplink resources;

[0152] The time domain end position of the earliest uplink resource among M uplink resources;

[0153] The end position of the time domain of the last uplink resource in the first uplink resource group containing M uplink resources.

[0154] Among the M uplink resources, the last uplink resource in the time domain represents the last uplink resource when the M uplink resources are sorted from earliest to latest by time.

[0155] Among the M uplink resources, the earliest uplink resource in the time domain represents the first uplink resource when the M uplink resources are sorted from earliest to latest by time.

[0156] For example, referring to Figure 6b, M=4, X=8, the first uplink resource group includes 8 time-domain resources. The terminal device selects 4 of these time-domain resources 1-4 (shown as shaded areas in Figure 6b) to send 4 data copies. If the reference time position is the time-domain end position of the earliest uplink resource among the 4 uplink resources corresponding to the uplink data copy transmission, then in this example, the time-domain start position of the receive time window is the time-domain end position of time-domain resource 1. At this time, the receive time window is shown as receive time window 3 in Figure 6b.

[0157] If the reference time position is the end position of the latest uplink resource in the time domain among the four uplink resources corresponding to the uplink data replica transmission, then in this example, the start position of the receive time window in the time domain is the end position of time domain resource 4. At this time, the receive time window is shown as receive time window 4 in Figure 6b.

[0158] If the reference time position is the end position of the latest uplink resource in the time domain among the eight uplink resources in the first uplink resource group where the uplink data replica transmission is located, then in this example, the start position of the receive time window in the time domain is the end position of time domain resource 8. At this time, the receive time window is shown as receive time window 5 in Figure 6b.

[0159] In one specific embodiment, the terminal device determines the end time position of the reception time window based on the start time position and the length of the reception time window. The length of the reception time window can be configured by the network device or specified by the communication standard protocol; this application does not impose any restrictions on this.

[0160] For example, the end time position of the receiving time window is the time position after the start position of the receiving time window delayed by a second time offset, and the second time offset is the length of the receiving time window.

[0161] In another specific embodiment, the terminal device may also determine the end time position of the receiving time window based on the end position of the last uplink resource in the time domain of the first uplink resource group containing the M uplink resources.

[0162] Specifically, the end time position of the receiving time window is the time position after the end position of the last uplink resource in the time domain of the first uplink resource group containing M uplink resources, delayed by the first time offset.

[0163] For example, referring to Figure 6b, the last uplink resource in the time domain of the first uplink resource group is time domain resource 8. The time domain end position of time domain resource 8 is delayed by the first time offset, which is the end time position of the receiving time window.

[0164] For example, referring to Figure 6a, the last uplink resource in the time domain of the first uplink resource group is located in time slot 2, and the first time offset is 5 time slots. Therefore, the end time position of the receiving time window is time slot 7.

[0165] It should be noted that the first time offset can be configured by the network device or specified by the communication standard protocol, and this application does not impose any restrictions on it.

[0166] In this embodiment, the terminal device can demodulate the response message using the Radio Network Temporary Identity (RNTI). The RNTI can be determined based on the resource parameter information of a reference uplink resource, which is one of M uplink resources.

[0167] In practice, the terminal device determines the RNTI, and based on the RNTI, the terminal device receives the response messages corresponding to the M uplink data copies within the receiving time window.

[0168] In specific implementation, the terminal device can determine the RNTI based on the reference uplink resources using any one of the following formulas (1)-(5). RNTI=1+t_PUSCH_id+10×f_PUSCH_id+X×OCC_index, (1)

[0169] Wherein, t_PUSCH_id represents the start subframe number or start time slot number of the reference uplink resource, or the end subframe number or end time slot number of the reference uplink resource. f_PUSCH_id represents the frequency domain index number of the reference uplink resource, OCC_index represents the orthogonal code index number of the reference uplink resource, X represents the scaling factor or scaling coefficient, the specific value of X can be specified by the standard protocol or configured by the network device, and × represents a mathematical product.

[0170] For example, when t_PUSCH_id is 1, f_PUSCH_id is 1, OCC_index is 1, and X is 2, RNTI is 14. RNTI = 1 + t_PUSCH_id + 10 × f_PUSCH_id + 60 × (SFN_id mod(Wmax / 10)) + X × [OCC_Index], (2)

[0171] Wherein, t_PUSCH_id represents the starting subframe number or starting time slot number of the reference uplink resource, or the ending subframe number or ending time slot number of the reference uplink resource. f_PUSCH_id represents the frequency domain index number of the reference uplink resource, SFN_id represents the SFN where the first subframe of the reference uplink resource is located, mod() represents the modulo operation, OCC_index represents the orthogonal code index number of the reference uplink resource, X represents the scaling factor or scaling coefficient, Wmax represents a fixed value, and the specific values ​​of Wmax and X can be specified by the standard protocol or configured by the network device, for example, Wmax is 400, and × represents the mathematical product.

[0172] For example, when t_PUSCH_id is 1, f_PUSCH_id is 1, SFN_id is 10, Wmax is 30, OCC_index is 1, and X is 2, RNTI is 74. RNTI = 1 + floor(SFN_PUSCH_id / 4) + 256 × carrier_id + X × [OCC_Index], (3)

[0173] Wherein, SFN_PUSCH_id represents the SFN where the first subframe of the reference uplink resource is located, floor() represents the floor function, carrier_id represents the index of the carrier where the reference uplink resource is located, OCC_index represents the orthogonal code index number of the reference uplink resource, X represents the scaling factor or scaling coefficient, the specific value of X can be specified by the standard protocol or configured by the network device, and × represents the mathematical product.

[0174] For example, when SFN_PUSCH_id is 10, carrier_id is 1, OCC_index is 1, and X is 2, RNTI is 261. RNTI = 1 + floor(SFN_PUSCH_id / 4) + 256 × (H - SFN_PUSCH mod 2) + X × [OCC_Index], (4)

[0175] Wherein, SFN_PUSCH_id represents the SFN where the first subframe of the reference uplink resource is located, floor() represents the floor function, H-SFN_PUSCH represents the superframe number where the first subframe of the reference uplink resource is located, OCC_index represents the orthogonal code index number of the reference uplink resource, X represents the scaling factor or scaling coefficient, the specific value of X can be specified by the standard protocol or configured by the network device, and × represents the mathematical product.

[0176] For example, when SFN_PUSCH_id is 10, H-SFN_PUSCH is 10, OCC_index is 1, and X is 2, RNTI is 5. RNTI=1+s_PUSCH_id+14×t_PUSCH_id+14×80×f_PUSCH_id+14×X×8×ul_PUSCH_carrier_id+Y×[DMRS resource_index]+X×[OCC_index],(5)

[0177] Wherein, s_PUSCH_id represents the index of the starting OFDM symbol of the reference uplink resource, t_PUSCH_id represents the starting subframe number or starting time slot number of the reference uplink resource, or the ending subframe number or ending time slot number of the reference uplink resource, f_PUSCH_id represents the frequency domain index number of the reference uplink resource, ul_PUSCH_carrier_id represents the index of the uplink carrier of the reference uplink resource, OCC_index represents the orthogonal code index number of the reference uplink resource, DMRS resource_index represents the index of the DMRS resource of the reference uplink resource, X and Y represent scaling factors or scaling coefficients, the specific values ​​of X and Y can be specified by standard protocols or configured by network devices, and × represents mathematical multiplication.

[0178] For example, if s_PUSCH_id is 1, t_PUSCH_id is 1, f_PUSCH_id is 0, ul_PUSCH_carrier_id is 1, DMRS resource_index is 1, OCC_index is 1, Y is 1, and X is 2, then RNTI is 243.

[0179] In one specific embodiment, the reference uplink resource can be at least one of the following:

[0180] Among the M uplink resources, the uplink resource with the largest time-domain resource index and the largest frequency-domain resource index, or...

[0181] Among M uplink resources, the uplink resource with the largest time-domain resource index and the smallest frequency-domain resource index, or...

[0182] The uplink resource with the smallest time-domain resource index and the smallest frequency-domain resource index among M uplink resources, or...

[0183] Among M uplink resources, the uplink resource with the smallest time-domain resource index and the largest frequency-domain resource index, or...

[0184] The uplink resource with the largest time-domain resource index and the smallest frequency-domain resource index in the first uplink resource group containing M uplink resources, or,

[0185] Among the M uplink resources in the first uplink resource group, the uplink resource with the largest time-domain resource index and the largest frequency-domain resource index, or...

[0186] Among the M uplink resources in the first uplink resource group, the uplink resource with the smallest time-domain resource index and the largest frequency-domain resource index, or...

[0187] The uplink resource with the smallest time-domain resource index and the smallest frequency-domain resource index in the first uplink resource group containing M uplink resources.

[0188] Among the M uplink resources, the uplink resource with the largest time-domain resource index and the largest frequency-domain resource index can be the uplink resource occupied by the last data replica among the M data replicas.

[0189] Among the M uplink resources, the uplink resource with the smallest time-domain resource index and the smallest frequency-domain resource index can be the uplink resource occupied by the first data replica among the M data replicas.

[0190] For example, as shown in Figure 6c, the first uplink resource group includes 8 (i.e., M=8) uplink resources, with 4 uplink resources multiplexed in the time domain (corresponding to time domain resource indices 0, 1, 2, 3) and 2 uplink resources multiplexed in the frequency domain (corresponding to frequency domain resource indices 0, 1). If the reference uplink resource is the uplink resource with the largest time domain resource index and the largest frequency domain resource index among the 8 uplink resources in the first uplink resource group, then in this example, the reference uplink resource is the uplink resource with time domain resource index 3 and frequency domain resource index 1 in the first uplink resource group, i.e., uplink resource (3, 1) in the figure. If the reference uplink resource is the uplink resource with the largest time domain resource index and the smallest frequency domain resource index among the 8 uplink resources, then in this example, the reference uplink resource is the uplink resource with time domain resource index 3 and frequency domain resource index 0 in the first uplink resource group, i.e., uplink resource (3, 0) in the figure.

[0191] If the reference uplink resource is the uplink resource with the smallest time-domain resource index and the smallest frequency-domain resource index among the 8 uplink resources, then in this example, the reference uplink resource is the uplink resource in the first uplink resource group with a time-domain resource index of 0 and a frequency-domain resource index of 0, which is the uplink resource (0, 0) in the figure.

[0192] If the reference uplink resource is the uplink resource with the smallest time-domain resource index and the largest frequency-domain resource index among the 8 uplink resources, then in this example, the reference uplink resource is the uplink resource with a time-domain resource index of 0 and a frequency-domain resource index of 1 in the first uplink resource group, which is the uplink resource (0, 1) in the figure.

[0193] Furthermore, the resource parameter information for referencing uplink resources includes at least one of the following:

[0204] Those skilled in the art will understand that steps S501 to S502 can be considered as execution steps corresponding to step S101 of the embodiment shown in FIG1 above, and the two are complementary in terms of specific implementation principles and logic. Therefore, the explanation of the terms involved in this embodiment can be referred to the relevant description of the embodiment shown in FIG1, and will not be repeated here.

[0205] Please refer to Figure 7, which illustrates the flow of another communication method.

[0206] In this embodiment, the terminal device can send mutual reference information to the network device to indicate the uplink resource where the uplink data copy is located. The network device can perform an interference iterative cancellation operation based on the mutual reference information to correctly receive M data copies.

[0207] In step 701, the terminal device determines a first uplink resource group. The first uplink resource group includes X uplink resources, and all uplink resources in the first uplink resource group are associated with a first SSB.

[0208] In step 702, the terminal device sends M copies of uplink data on M uplink resources within the first uplink resource group.

[0209] In step 703, the terminal device sends mutual reference information to the network device.

[0210] In this embodiment, the cross-reference information of each uplink data replica transmission or association can indicate the information of the uplink resources in the first uplink resource group where the uplink resource corresponding to the uplink data replica transmission is located, excluding the uplink resource itself, or the information of the uplink resources occupied by other uplink data replicas besides the uplink data replica in the M uplink data replica transmissions.

[0211] Specifically, the information of the uplink resources can be the index or number of the uplink resources. For example, if the first uplink resource group includes 8 uplink resources and the cross-reference information of a certain uplink data copy transmission is 11000001, then the first, second, and eighth uplink resources in the first uplink resource group are used to transmit uplink data copies.

[0212] In this embodiment, the mutual reference information can be carried on mutual reference information transmission resources, which are used to transmit the mutual reference information. Specifically, the mutual reference information transmission resources can be Physical Uplink Control Channel (PUCCH) resources. The time offset between the time domain location of the uplink control channel resource associated with each uplink resource and the time domain location of the uplink resource itself is a third time offset.

[0213] For example, the time-domain position of the PUCCH resource is delayed by a third time offset to the time-domain position of the uplink resource.

[0214] For example, the time-domain location of the uplink resource is delayed by a third time offset to the time-domain location of the PUCCH resource.

[0215] In this embodiment, cross-reference information can also be carried in random access channel resources. Each random access channel resource is associated with one of the M uplink resources. The association between random access channel resources and uplink resources can be configured by network devices or defined by standard protocols; this application does not impose any restrictions on this.

[0216] For example, if the terminal device sends uplink data on all uplink resources in the first uplink resource group, it means that the terminal device has sent multiple copies of data. In this case, the terminal device needs to use the random access channel resources associated with M uplink resources to send the preamble.

[0217] For example, if a terminal device sends uplink data on an uplink resource in the first uplink resource group, it means that the terminal device has not sent a copy of the data, and the terminal device may not use the random access channel resource to send the preamble.

[0218] In this embodiment, cross-reference information can also be carried in Physical Uplink Shared Channel (PUSCH) resources. The time offset between the time domain resource location of the PUSCH associated with each uplink resource and the time domain location of the uplink resource is the third time offset.

[0219] For example, the time-domain location of the PUSCH resource is delayed by a third time offset to the time-domain location of the uplink resource.

[0220] For example, the time-domain location of the uplink resource is delayed by a third time offset to the time-domain location of the PUSCH resource.

[0221] Those skilled in the art will understand that steps S701 to S702 can be considered as execution steps corresponding to steps S101 to S102 in the embodiment shown in FIG1 above, and the two are complementary in terms of specific implementation principles and logic. Therefore, the explanation of the terms involved in this embodiment can be referred to the relevant description of the embodiment shown in FIG1, and will not be repeated here.

[0222] In a non-limiting embodiment, according to the existing SSB and uplink resource mapping rules, if one SSB corresponds to more than two uplink resources, the data copy can be transmitted within the current first association period. Otherwise, the data copy needs to be transmitted within the next first association period, resulting in a large transmission delay.

[0223] To reduce transmission latency, in this embodiment, the terminal device can determine the target mapping rate between uplink resources and SSBs based on the maximum number of replica transmissions. The terminal device completes the mapping between SSBs and uplink resources according to the target mapping rate, which is the number of SSBs associated with each uplink resource, or in other words, the value of N is determined according to the target mapping rate between SSBs and uplink resources.

[0224] The maximum number of copy transmissions can be configured by the network device for the terminal device.

[0225] In one specific implementation, the target mapping rate is the minimum of the initial mapping rate of the SSB and the uplink resource and a first value, where the first value is the reciprocal of the maximum number of replica transmissions.

[0226] For example, if the initial mapping rate is 1 / 4, the maximum number of replica transfers is 8, and the first value is 1 / 8, then the target mapping rate is 1 / 8.

[0227] In another specific implementation, if the initial mapping rate is less than 1, the target mapping rate is the product of the pre-configured mapping rate and the first value.

[0228] For example, if the initial mapping rate is 1 / 4, the maximum number of replica transfers is 8, and the first value is 1 / 8, then the target mapping rate is 1 / 32.

[0229] In another specific implementation, if the initial mapping rate is greater than or equal to 1, the target mapping rate is the first value.

[0230] For example, if the initial mapping rate is 2, the maximum number of replica transfers is 8, and the first value is 1 / 8, then the target mapping rate is 1 / 8.

[0231] Please refer to Figure 8, which illustrates the flow of another communication method.

[0232] In this embodiment, the network device can send a first message to the terminal device to indicate whether to apply the uplink data copy transmission mechanism or not, or to indicate whether to enable or disable (or activate or deactivate) the transmission of data copies, so as to improve the flexibility of data transmission.

[0233] Whether to apply the uplink data copy transmission mechanism is related to changes in network load. Network devices can determine changes in service load within a cell based on statistics and forecasts. Based on this, network devices can instruct terminal devices whether to apply the uplink data copy transmission mechanism.

[0234] In step 801, the terminal device receives the first information. Correspondingly, the network device sends the first information.

[0235] In this embodiment, if the first information indicates that the uplink data copy transmission mechanism is applied, the terminal device applies the uplink data copy transmission mechanism; if the first information indicates that the uplink data copy transmission mechanism is not applied, the terminal device does not apply the uplink data copy transmission mechanism.

[0236] Specifically, the first information can be carried in any of the following downlink messages: Downlink Control Information (DCI), Paging Early Indication (PEI), or System Information Block (SIB).

[0237] Specifically, a bit is set in the paging DCI or PEI to enable / de-enable the data copy transmission mechanism, or an enable / de-enable indicator is carried in the SIB to indicate whether to enable or de-enable the transmission of M uplink data copies.

[0238] In this embodiment, when the first information is only used to indicate the application uplink data copy transmission mechanism, the value of M can be determined by the terminal device itself.

[0239] Furthermore, in addition to enabling the data copy transmission mechanism, the network device can also indicate the number of transmissions through first information, such as the value of M or the maximum number of uplink data copy transmissions K.

[0240] In one specific implementation, the first information indicates the value of M, that is, the first information indicates that the terminal device transmits M uplink data copies according to a fixed number of transmissions M, and the fixed number of transmissions M.

[0241] Specifically, a bit field is set in the paging DCI or PEI to enable or disable the data copy transmission mechanism and the number of transmissions, or an indication is carried in the SIB to indicate whether the uplink data copy transmission mechanism is applied or not.

[0242] For example, when the traffic volume within the cell is relatively low, the network device can instruct the terminal device to apply the uplink data copy transmission mechanism; when the traffic volume within the cell is relatively high, the network device can instruct the terminal device not to apply the uplink data copy transmission mechanism. In another specific implementation, the first information indicates the maximum number of uplink data copy transmissions K. In this case, the specific value of the number of uplink data copy transmissions M is determined by the terminal device itself, and the value of M is less than or equal to K. That is, the network device instructs the terminal device to transmit M uplink data copies according to a variable number of transmissions, and the maximum number of uplink data copy transmissions K, through the first information.

[0243] For example, when the traffic volume in the cell is relatively small (or the number of terminal devices is relatively small), the terminal devices can transmit uplink data in a fixed number of transmissions; when the traffic volume in the cell is relatively large (or the number of terminal devices is relatively large), the terminal devices can transmit uplink data in a variable number of transmissions.

[0244] In an alternative embodiment, the network device may also send a second message, which the terminal device receives accordingly. The second message may indicate the value of M or the maximum number of uplink data copy transmissions K.

[0245] In this embodiment, the second information is different from the first information. The second information can also be carried in the paging DCI or PEI. The way the second information is set in the paging DCI or PEI is similar to that of the first information, and will not be described again here.

[0246] When the network device enables the terminal device to transmit data copies via the first information, the terminal device executes step 802.

[0247] In step 802, the terminal device sends M copies of uplink data on M uplink resources within the first uplink resource group.

[0248] Those skilled in the art will understand that step S802 can be considered as an execution step corresponding to step S101 of the embodiment shown in FIG1 above, and the two are complementary in terms of specific implementation principles and logic. Therefore, the explanation of the terms involved in this embodiment can be referred to the relevant description of the embodiment shown in FIG1, and will not be repeated here.

[0249] Please refer to Figure 9, which shows a communication device 90, which may include a communication module 901.

[0250] The communication module 901 may or may not use the uplink data copy transmission mechanism. When the uplink data copy transmission mechanism is used, the communication module 901 is used to send M uplink data copies on M uplink resources in the first uplink resource group.

[0252] In another non-limiting embodiment, when an uplink data copy transmission mechanism is applied, the communication module 901 is used to receive M uplink data copies on M uplink resources within the first uplink resource group.

[0253] In specific implementations, the aforementioned communication device 90 may correspond to a chip with communication function in a network device, such as a SOC or baseband chip; or to a chip module in a network device that includes a chip with communication function; or to a chip module with a chip that has data processing function; or to a network device.
