Description

Technical Field

[0001] Embodiments of the present application relate to the field of wireless communications, and in particular, to methods and apparatuses for uplink data transmission. Background Art

[0002] A significant feature of the fifth-generation (5G) mobile communication system compared with the fourth-generation (4G) mobile communication system is that it increases the support for ultra-reliable and low-latency communications (URLLC) services. There are many types of URLLC services, and typical use cases include industrial control, driverless, remote surgery, and smart grid, etc. For URLLC services, a typical requirement is that the reliability of sending 32 bytes of data within 1 millisecond (ms) reaches 99.999%. It should be noted that the above performance indicators are only examples, and different URLLC services may have different requirements for reliability. For example, in some extremely demanding industrial control application scenarios, the transmission success probability of URLLC service data needs to reach 99.9999999% within 0.25 ms. Summary of the Invention

[0003] Embodiments of the present application provide a method for uplink data transmission, which is used to improve the reliability of data transmission.

[0004] In a first aspect, a method for uplink data transmission is provided. The execution subject of this method is a terminal device or a module in the terminal device. Here, the terminal device is used as an example of the execution subject for description. The terminal device receives first indication information from a network device, and the first indication information indicates the number K1 of resources in a first resource bundle, where K1 is a positive integer; the terminal device obtains the number R1 of copies of the uplink data, where R1 is a positive integer; the terminal device sends the uplink data to the network device on the resources in the first resource bundle according to the number K1 of resources in the first resource bundle and the number R1 of copies of the uplink data.

[0005] By implementing the method described in the first aspect, the network device can flexibly configure the number K1 of resources in the resource bundle and the number R1 of copies of the uplink data. When the terminal device misses some resources in the resource bundle due to channel access failure, it can still continue to transmit the uplink data on the remaining resources in the resource bundle, thereby improving the reliability of data transmission.

[0006] In a possible implementation of the first aspect, obtaining the number of copies of the uplink data specifically includes: receiving second indication information from the network device, where the second indication information indicates the number of copies R1 of the uplink data.

[0008] By implementing the above method, the network device can configure the number of CGs in the time domain within the resource bundle to be greater than the number of transmission times that meet the reliability (i.e., the number of copies R1 of the uplink data). When the terminal device misses some CGs within a resource bundle due to failing to successfully access the channel, it can continue to transmit the copies of the uplink data on the remaining CGs, thereby ensuring the reliability of data transmission.

[0010] By implementing the above method, when the terminal device misses some CGs within a CG bundle due to failing to successfully access the channel, it can continue to transmit the copies of the uplink data on other CG bundles, thereby ensuring the reliability of data transmission.

[0011] In a possible implementation of the first aspect, the terminal device sends third indication information to the network device, where the third indication information indicates whether the first data associated with the third indication information is the first copy of the uplink data, or the third indication information indicates whether the first data associated with the third indication information is the last copy of the uplink data, or the third indication information indicates that the first data associated with the third indication information is the r-th copy of the uplink data, and r is a positive integer not greater than R1.

[0012] By implementing the above method, the network device can know on which CGs the terminal device has sent copies of the uplink data through the third indication information, and the network device performs HARQ soft combining on the data received on these CGs, that is, the network device combines the data on these CGs together and decodes it, thereby improving the transmission efficiency.

[0013] In a possible implementation manner of the first aspect, the terminal device sends fourth indication information to the network device, and the fourth indication information indicates whether the network device sends feedback information on the first uplink data.

[0014] By implementing the above method, the network device can determine whether to perform HARQ feedback on the uplink data according to the fourth indication information, thereby reducing the signaling overhead caused by HARQ feedback and improving the resource utilization rate.

For example, it can be a central unit (CU) or a distributed unit (DU). The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the radio access network device. In the embodiments of the present application, the radio access network device is simply referred to as the network device. Unless otherwise specified, the network device refers to the radio access network device. In the embodiments of the present application, the device for implementing the functions of the network device can be the network device; it can also be a device that can support the network device to implement this function, such as a chip system. This device can be installed in the network device or used in cooperation with the network device. In the technical solutions provided in the embodiments of the present application, the device for implementing the functions of the network device is the network device as an example to describe the technical solutions provided in the embodiments of the present application.

[0045] The terminal device involved in the embodiments of this application may also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality terminal device, an augmented reality terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in remote surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, and so on. The embodiments of this application do not limit the specific technologies and specific device forms adopted by the terminal device. In the embodiments of this application, the device for implementing the functions of the terminal device may be the terminal device; it may also be a device capable of supporting the terminal device to implement the functions, such as a chip system, and this device may be installed in the terminal device or used in matching with the terminal device. In the embodiments of this application, the chip system may be composed of chips or may include chips and other discrete devices. In the technical solutions provided by the embodiments of this application, taking the device for implementing the functions of the terminal device as the terminal device as an example, the technical solutions provided by the embodiments of this application are described.

[0046] The network device and the terminal device may be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they may also be deployed on the water surface; they may also be deployed on airplanes, balloons, and artificial satellites in the air. The embodiments of this application do not limit the application scenarios of the network device and the terminal device.

[0047] The network device and the terminal device may communicate through authorized spectrum, or may communicate through unlicensed spectrum, or may communicate through both authorized spectrum and unlicensed spectrum at the same time. The network device and the terminal device may communicate through spectrum below 6 gigahertz (GHz), or may communicate through spectrum above 6 GHz, or may also use spectrum below 6 GHz and spectrum above 6 GHz at the same time. The embodiments of this application do not limit the spectrum resources used between the network device and the terminal device.

[0048] In a communication system, the terminal device may access the network device and communicate with the network device. Exemplarily, a network device may manage one or more (such as 3 or 6, etc.) cells, and the terminal device may access the network device in at least one of the one or more cells and communicate with the network device in the cell where the terminal device is located. In the embodiments of this application, at least one may be 1, 2, 3, or more, and the embodiments of this application do not make any restrictions.

[0049] One implementation of the uplink data transmission between the terminal device and the network device on the unlicensed spectrum can be grant free, that is, the terminal device uses the grant-free resources to send uplink data to the network device. In grant-free transmission, the uplink transmission of the terminal device does not need to be completed through the scheduling of the network device. For example, when the uplink data arrives, the terminal device does not need to send a scheduling request (SR) to the network device and wait for the dynamic grant of the network device, but can directly use the transmission resources pre-allocated by the network device and the specified transmission parameters to send the uplink data to the network device. In the embodiments of the present application, "grant-free transmission" is also referred to as "grant-free scheduling", and "grant-free resources" are also referred to as "configured grant (CG)". When the terminal device uses CG for uplink data transmission, how to improve the reliability of data transmission is an urgent problem to be solved.

[0050] Figure 2 It is a schematic flowchart of an uplink data transmission method provided by the embodiments of the present application. This embodiment relates to the specific process of uplink data transmission between the network device and the terminal device. Figure 2 As shown, the method may include: S101, S102, and S103.

[0051] S101. The network device sends first indication information to the terminal device, and the first indication information indicates the number K1 of resources within a resource bundle, where K1 is a positive integer. Correspondingly, the terminal device receives the first indication information from the network device.

[0052] Specifically, the above first indication information may be a radio resource control (RRC) message, such as an RRC Reconfiguration message. The above resource bundle is a CG bundle, and the CG bundle may appear periodically. In the embodiments of the present application, the bundle may be referred to as "bundle", and a CG bundle may also be referred to as "a bundle of configured grant". The first indication information indicates the number K1 of CGs in the time domain within a CG bundle. The K1 CGs are used to transmit the same transport block (TB). In the embodiments of the present application, the CG can be divided into the following two types.

[0053] The first type of CG: The network device configures the transmission parameters of CG for the terminal device through the parameters (such as ConfiguredGrantConfig) in the RRC message, for example, configures one or more of the following parameters: period, open-loop power control related parameters, waveform, redundancy version, redundancy version sequence, repetition times, frequency hopping pattern, resource allocation type, hybrid automatic repeat request (HARQ) process number, demodulation reference signal (DMRS) related parameters, modulation and coding scheme (MCS) table, resource block group (RBG) size, time-domain resource location, frequency-domain resource location, and MCS.

[0054] The second type of CG: The network device configures some or all of the transmission parameters for the terminal device through the RRC message, for example, configures one or more of the following parameters: period of the time-domain resource, open-loop power control related parameters, waveform, redundancy version, redundancy version sequence, repetition times, frequency hopping pattern, resource allocation type, MCS table, DMRS related parameters, and HARQ process number; and, the network device sends physical layer signaling to the terminal device, such as downlink control information (DCI), to activate the second type of CG. Optionally, the DCI can also be used to configure some transmission parameters, for example, configure one or more of the following parameters: time-domain resource location, frequency-domain resource location, DMRS related parameters, and MCS. The DCI can be carried by the physical downlink control channel (PDCCH).

[0055] When the terminal device uses the above two types of CG for uplink transmission, the terminal device can directly use the CG pre-configured by the network device to send uplink data to the network device without sending an SR to the network device and waiting for the dynamic authorization of the network device. It should be noted that the second type of CG needs to be activated by physical layer signaling before it can be used by the terminal device.

[0056] The network device can configure one set or multiple sets of CG for the terminal device. Specifically, in the scenario of carrier aggregation, the terminal device has multiple serving cells, and each serving cell is configured with one set or multiple sets of CG separately. Optionally, each serving cell includes multiple bandwidth parts (BWPs), and different BWPs are configured with different CGs.

[0057] S102. Obtain the number R1 of repetitions of the uplink data, where R1 is a positive integer. The number R1 of repetitions of the uplink data can also be understood as: the number of times the terminal device transmits the uplink data is R1, or, the uplink data has R1 transmission opportunities. Exemplarily, R1 equals 4, indicating that the uplink data has 4 repetitions, that is, the number of times the terminal device transmits the uplink data is 4, or, the uplink data has 4 transmission opportunities. Specifically, the terminal device can obtain the number R1 of repetitions of the uplink data through the following two methods.

[0058] Method 1: The network device sends second indication information to the terminal device, and the second indication information indicates the number R1 of repetitions of the uplink data. Correspondingly, the terminal device receives the second indication information from the network device. Specifically, the second indication information can be an RRC message, such as an RRC reconfiguration message. The number R1 of repetitions of the uplink data can be configured by the network device for the terminal device according to the reliability requirement.

[0059] Method 2: The terminal device determines the number R1 of repetitions of the uplink data according to the number K1 of resources in the above-mentioned first resource bundle, that is, R1 equals K1.

[0060] S103. The terminal device sends the above-mentioned uplink data to the network device on the resources in the first resource bundle according to the number K1 of resources in the first resource bundle and the number R1 of repetitions of the uplink data. Correspondingly, the network device receives the uplink data from the terminal device on the resources in the first resource bundle according to the number K1 of resources in the first resource bundle and the number R1 of repetitions of the uplink data. Specifically, it includes the following Method 1 and Method 2.

[0061] Method 1: The terminal device sends N1 copies of the above-mentioned uplink data to the network device on the resources in the first resource bundle. Correspondingly, the network device receives N1 copies of the above-mentioned uplink data from the terminal device on the resources in the first resource bundle. Among them, N1 is a positive integer not greater than K1, N1 is a positive integer not greater than R1, and K1 is greater than R1.

[0062] Specifically, the terminal device performs a channel access process within the first resource bundle, and the terminal device completes channel access on the nth resource in the resource bundle, where n is a positive integer not greater than K1. In the embodiments of the present application, completing channel access on a resource can be understood as: completing channel access before any transmission start point of a resource. A resource can have multiple transmission start points. Exemplarily, the time domain position of a resource is symbols 1 to 5 in a time slot, and the transmission start points of the resource are located at symbols 2 and 3. When the terminal device completes channel access before symbol 2 or symbol 3, it means that the terminal device accesses the resource, and thus can perform data transmission on the resource.

[0063] After the terminal device completes channel access for the nth resource in the resource bundle, the terminal device sends N1 copies of the uplink data to the network device on the nth to the mth resources in the resource bundle, where m is a positive integer not greater than K1, m is greater than or equal to n, and N1 = m - n + 1. That is, the terminal device sends one copy of the uplink data on each of the nth to the mth resources. When K1 - n + 1 is greater than or equal to R1, that is, n is less than or equal to K1 - R + 1, m = R + n - 1, and at this time, N1 = R1. When K1 - n + 1 is less than R1, that is, n is greater than K1 - R + 1, m = K1, and at this time, N1 < R1.

[0064] Exemplarily, the network device configures a set of CGs for the terminal device. As Figure 3 shown, the number of CGs in the time domain within a resource bundle in this set of CGs is 6. Assume that the number of copies R1 of the uplink data obtained by the terminal device is equal to 4. If the terminal device completes channel access for the 3rd resource in the resource bundle (i.e., Figure 3 resource 3 in

[0065] ), then N1 = 4.

[0066] Method 2: The terminal device sends N1 copies of uplink data to the network device on the resources in the first resource bundle and sends N2 copies of uplink data to the network device on the resources in the second resource bundle. Correspondingly, the network device receives N1 copies of uplink data from the terminal device on the resources in the first resource bundle and receives N2 copies of uplink data from the terminal device on the resources in the second resource bundle. Among them, the number of resources in the second resource bundle is K2, K2 is a positive integer, N1 is a positive integer not greater than K1, N2 is a positive integer not greater than K2, and N1 + N2 is not greater than R1.

[0067] Specifically, the terminal device performs the channel access process within the first resource bundle. The terminal device completes channel access for the pth resource in the first resource bundle, where p is a positive integer not greater than K1. The terminal device sends N1 copies of the uplink data to the network device on the pth to the qth resources in the resource bundle, where q is a positive integer not greater than K1, q is greater than or equal to p, and N1 = q - p + 1.

[0068] When K1 - p + 1 is less than R1, that is, when the number of repeated transmissions of the above uplink data within the first resource bundle is less than R1, the above uplink data cannot meet the reliability requirements within the first resource bundle, and the terminal device sends a copy of the uplink data to the network device on the resources of the second resource bundle. Specifically, the terminal device performs a channel access procedure within the second resource bundle, and the terminal device completes channel access on the x-th resource of the second resource bundle, where x is a positive integer not greater than K2. The terminal device sends N2 copies of the uplink data to the network device on the x-th resource to the y-th resource of the resource bundle, where y is a positive integer not greater than K2, y is greater than or equal to x, and N2 = y - x + 1. At this time, the number of copies of the uplink data actually sent by the terminal device to the network device is equal to N1 + N2. Among them, the HARQ process used by the terminal device to send the copy of the uplink data within the first resource bundle is the same as the HARQ process used by the terminal device to send the copy of the uplink data within the second resource bundle.

[0069] Optionally, when y < K2, that is, when there are remaining resources within the second resource bundle, the terminal device can send new data to the network device on the above remaining resources.

[0070] Exemplarily, the network device configures two sets of CGs for the terminal device, namely CG1 and CG2. The number of CGs in the time domain within one resource bundle in CG1 is 4, and the number of CGs in the time domain within one resource bundle in CG2 is 6. The terminal device completes channel access on the 3rd CG in one resource bundle of CG1 ( Figure 4 resource number 3 in the CG1 bundle), then the terminal device can only transmit 2 copies of the uplink data within this resource bundle (that is, N1 = 2 < R1), which cannot meet the reliability requirements. At this time, the terminal device continues to send copies of the uplink data within the resource bundle of CG2. Exemplarily, the terminal device completes channel access on the 2nd CG ( Figure 4 resource number 6 in the CG2 bundle) in one resource bundle of CG2, then the terminal device sends the copy of the uplink data to the network device on the 2nd CG ( Figure 4 resource number 6 in the CG2 bundle) and the 3rd CG ( Figure 4 resource number 7 in the CG2 bundle) in this resource bundle, so that the actual number of transmissions of the uplink data reaches 4 times. Optionally, the terminal device can continue to transmit copies of the uplink data on the remaining CGs within the CG2 resource bundle, or can also send new data on the remaining CGs within the resource bundle of this CG2.

[0071] By implementing the above method, when the terminal device misses some CGs within a CG bundle due to failing to successfully access the channel, it can continue to transmit copies of the uplink data on other CG bundles, thereby ensuring the reliability of data transmission.

[0072] Figure 5 FIG. 4 is a schematic flowchart of an uplink data transmission method provided by an embodiment of the present application. This embodiment relates to the specific process of uplink data transmission between a network device and a terminal device. Figure 5 As shown, the method may include: S201, S202, S203, and S204.

[0073] S201. The network device sends first indication information to the terminal device. The first indication information indicates the number K1 of resources within a resource bundle, where K1 is a positive integer. For specific description, refer to Figure 2 step S101 in

[0074] S202. Obtain the number R1 of copies of the uplink data, where R1 is a positive integer. For specific description, refer to Figure 2 step S102 in

[0075] S203. The terminal device sends the above uplink data to the network device on the resources in the first resource bundle according to the number K1 of resources in the first resource bundle and the number R1 of copies of the uplink data. For specific description, refer to Figure 2 step S103 in

[0076] S204. The terminal device sends third indication information to the network device. Correspondingly, the network device receives the third indication information from the terminal device. The third indication information indicates whether the first data associated with the third indication information is the first copy of the above uplink data, or the third indication information indicates whether the first data associated with the third indication information is the last copy of the above uplink data, or the third indication information indicates that the first data associated with the third indication information is the r-th copy of the above uplink data, where r is a positive integer not greater than R1.

[0077] The third indication information may be carried in CG-UCI (configured grant uplink control information). The terminal device may send the above third indication information to the network device on the CG, or the terminal device may send the above third indication information to the network device on the resources of the reserved physical uplink control channel (PUCCH).

[0078] When the time-frequency resource carrying the third indication information is the same as the time-frequency resource carrying the first data, or when the time-frequency resource carrying the third indication information and the time-frequency resource carrying the first data satisfy a preset relationship, the third indication information is associated with the first data, and the preset relationship may be pre-set by the network device through high-layer signaling.

[0079] The actual number of copies of the above uplink data sent by the terminal device is R2. When transmitting the uplink data using Method 1 in S103, R2 is equal to N1; when transmitting the uplink data using Method 2 in S103, R2 is equal to N1 + N2. When the terminal device sends any one of the R2 copies of the uplink data, the terminal device sends the third indication information to the network device, and the third indication information may indicate any one of the following three items:

[0080] First, the third indication information indicates whether the first data associated with the third indication information is the first copy of the above uplink data. Specifically, the third indication information indicates whether the first data is the first copy of the above uplink data through 1 bit. Exemplarily, when the bit is "0", it means that the first data is not the first copy of the above uplink data, and when the bit is "1", it means that the first data is the first copy of the above uplink data; or, when the bit is "1", it means that the first data is not the first copy of the above uplink data, and when the bit is "0", it means that the first data is the first copy of the above uplink data. In the embodiments of the present application, the Wth copy may also be expressed as copy W - 1, where W is a positive integer.

[0081] Second, the third indication information indicates whether the first data associated with the third indication information is the last copy of the above uplink data. Specifically, the third indication information indicates whether the first data is the last copy of the above uplink data through 1 bit. Exemplarily, when the bit is "0", it means that the first data is not the last copy of the above uplink data, and when the bit is "1", it means that the first data is the last copy of the above uplink data; or, when the bit is "1", it means that the first data is not the last copy of the above uplink data, and when the bit is "0", it means that the first data is the last copy of the above uplink data;

[0082] Third, the third indication information indicates that the first data associated with the third indication information is the rth copy (which can also be called copy r - 1) of the above uplink data, where r is a positive integer not greater than R1. Specifically, the third indication information indicates that the first data is the rth copy among the R1 copies of the above uplink data. The third indication information is passed through log2 R1One bit indicates that the first data associated with the third indication information is the r-th copy. Exemplarily, when R1 is equal to 4, this third bit field is indicated by 2 bits, where bit "00" indicates that the first data is the 1st copy among the R1 copies of the above uplink data, bit "01" indicates that the first data is the 2nd copy among the R1 copies of the above uplink data, bit "10" indicates that the first data is the 3rd copy among the R1 copies of the above uplink data, and bit "11" indicates that the first data is the 4th copy among the R1 copies of the above uplink data.

[0083] By implementing the above method, the network device can know on which CGs the terminal device has sent the copies of the uplink data through the third indication information, and the network device performs HARQ soft combining on the data received on these CGs, that is, the network device combines the data on these CGs together and decodes it, thereby improving the transmission efficiency.

[0084] Figure 6 It is a schematic flowchart of an uplink data transmission method provided by an embodiment of this application. This embodiment relates to the specific process of uplink data transmission between a network device and a terminal device. Figure 2 As shown, the method may include: S301, S302, S303, and S304.

[0085] S301. The network device sends first indication information to the terminal device, and this first indication information indicates the number K1 of resources within a resource bundle, where K1 is a positive integer. For specific description, refer to Figure 2 step S101 in

[0086] S302. Obtain the number R1 of copies of the uplink data, where R1 is a positive integer. For specific description, refer to Figure 2 step S102 in

[0087] S303. The terminal device sends the above uplink data to the network device on the resources in the first resource bundle according to the number K1 of resources within the first resource bundle and the number R1 of copies of the uplink data. For specific description, refer to Figure 2 step S103 in

[0088] S304. The terminal device sends fourth indication information to the network device, and this fourth indication information indicates whether the network device sends feedback information on the above first uplink data. Specifically, this fourth indication information may be carried on the CG-UCI, or carried in other physical layer signaling.

[0089] The method for the fourth indication information to indicate whether the network device sends feedback information on the above first uplink data specifically includes operation 1 and operation 2.

[0090] Operation 1: The terminal device determines whether HARQ feedback is required for the uplink data.

[0091] The network device configures one or more logical channels for the terminal device. The terminal device receives the configuration information of the logical channels from the network device, and the configuration information indicates whether HARQ feedback is required for each of the one or more logical channels.

[0092] Exemplarily, the network device configures logical channel 1, logical channel 2, and logical channel 3 for the terminal device. Among them, the data in logical channel 1 requires HARQ feedback. If the uplink data sent by the terminal device contains data from logical channel 1, the uplink data requires HARQ feedback; if the uplink data sent by the terminal device does not contain data from logical channel 1, the uplink data does not require HARQ feedback.

[0093] Operation 2: The terminal device indicates to the network device whether to send HARQ feedback information for the uplink data through the fourth indication information. Specifically, the fourth indication information indicates whether to send HARQ feedback information for the uplink data through 1 bit. When the value of this bit is "1", it means that the uplink data requires HARQ feedback. When the value of this bit is "0", it means that the uplink data does not require HARQ feedback; or when the value of this bit is "0", it means that the uplink data requires HARQ feedback, and when the value of this bit is "1", it means that the uplink data does not require HARQ feedback.

[0094] By implementing the above method, the network device can determine whether to perform HARQ feedback on the uplink data according to the fourth indication information, thereby reducing the signaling overhead caused by HARQ feedback and improving resource utilization.
