Abstract

In a scenario of frequency domain resources such as multiple CCs, when a terminal device sends uplink data by using a configuration authorization resource on one of the frequency domain resources (e.g., a CC), the terminal device may indicate, to a network device through UCI, the configuration authorization resource used when the terminal device sends the uplink data. Therefore, when the configured authorized resource does not correctly receive the uplink data sent by the terminal device, the network device can schedule the terminal device to retransmit the data on the frequency domain resource corresponding to the configured authorized resource according to the UCI, thereby reducing the resource overhead of data retransmission while ensuring the transmission reliability of the uplink data.

Description

Data transmission method, communication device, and storage medium
Technical Field
Embodiments of the present disclosure relate to communications technologies, and in particular, to a data transmission method, a communication apparatus, and a storage medium.
Background
Future 5G communication systems introduce the concept of periodically configuring granted resources (CGs). After the network device configures the configuration authorized resource for the terminal device and activates the terminal device to use the configuration authorized resource, the terminal device may send ultra-reliable and low latency communications (URLLC) service data to the network device using the configuration authorized resource. In the prior art, if the network device does not correctly receive the URLLC service data sent by the terminal device using the configuration authorization resource, and the identifier of the terminal device is not resolved, the network device cannot know that the terminal device has sent the data. In this scenario, the network device may not schedule resources for retransmitting data for the terminal device, and cannot meet the requirement of URLLC service on transmission reliability.
At present, in order to solve the above problem, the terminal device may send, to the network device, an SR using a resource allocated by the network device for sending an uplink Scheduling Request (SR) while sending the URLLC service data using the configuration authorization resource, so as to indicate, to the network device, that the terminal device has data to send through the SR. Therefore, even if the network device does not correctly receive the URLLC service data sent by the terminal device using the configuration authorization resource, the network device still can know that the terminal device has data to send through the SR sent by the terminal device without resolving the identifier of the terminal device. In this scenario, the network device may schedule a resource for retransmitting data for the terminal device, so that the terminal device may retransmit the URLLC service data using the resource scheduled by the network device, thereby ensuring the transmission reliability of the URLLC service.
Carrier Aggregation (CA) is a process of aggregating 2 or more carrier elements (CCs) to support a larger transmission bandwidth. In a CA scenario, when a network device may configure the above-mentioned configured authorized resource for a terminal device on multiple CCs, if the network device does not correctly receive URLLC service data sent by the terminal device using the configured authorized resource on one CC, and does not resolve an identifier of the terminal device, the network device may schedule a resource for retransmitting data on each CC based on an SR sent by the terminal device, resulting in a large resource overhead.
Disclosure of Invention
In view of this, embodiments of the present application provide a data transmission method, a communication apparatus, and a storage medium, so as to solve the technical problem that in a CA scenario, when a network device does not correctly receive uplink data sent by a terminal device on a configured authorized resource, a retransmission is scheduled for the terminal device based on an SR, which results in a large resource overhead.
In a first aspect, a data transmission method is provided, including:
after obtaining the at least two configuration authorized resources, the terminal device may use any one of the at least two configuration authorized resources to configure an authorized resource (for short, a first configuration authorized resource), send uplink data to the network device, and send uplink control information to the network device, so as to indicate, to the network device, the first configuration authorized resource used by the terminal device to send the uplink data through the uplink control information.
In a second aspect, there is provided a communication device comprising means for performing the steps of the first aspect above.
In a third aspect, the present application provides a communication device comprising at least one processor and a memory, the at least one processor being configured to perform the method provided in the first aspect above.
In a fourth aspect, the present application provides a communications device comprising at least one processor configured to perform the method provided by the first aspect above, and an interface circuit.
In a fifth aspect, the present application provides a program for performing the method of the first aspect above when executed by a processor.
A sixth aspect provides a program product, e.g. a computer readable storage medium, comprising the program of the fifth aspect.
In a seventh aspect, a communication device is provided, which is connected to a memory and is used to read and execute the program stored in the memory so as to implement the method of the first aspect. The communication device may comprise means, modules or circuits for performing the method provided in the first aspect above. The communication device may be a terminal device, or may be a module applied to the terminal device, for example, a chip applied to the terminal device.
In the above aspects, in a CA scenario, when a terminal device uses a configuration grant resource on one CC to send uplink data, the terminal device may indicate, to a network device, the configuration grant resource used when sending the uplink data through a UCI. Therefore, when the configured authorized resource does not correctly receive the uplink data sent by the terminal device, the network device can schedule the terminal device to retransmit the data on the frequency domain resource corresponding to the configured authorized resource according to the UCI, thereby reducing the resource overhead of data retransmission while ensuring the transmission reliability of the uplink data.
In the above aspects, the terminal device may implicitly indicate, to the network device, the first configuration grant resource used by the terminal device to send the uplink data through the transmission parameter of the uplink control information. For example, the terminal device may obtain a mapping relationship between a transmission parameter of the uplink control information and the configuration authorization resource. In the mapping relationship, one transmission parameter may correspond to at least one configuration grant resource. After acquiring the mapping relationship, the terminal device may determine, according to the mapping relationship, a transmission parameter of the uplink control information corresponding to the first configuration authorized resource. In this implementation manner, the terminal device may send the uplink control information to the network device by using the transmission parameter of the uplink control information, so as to implicitly indicate the uplink data sent by using the first configuration grant resource through the transmission parameter.
In a specific implementation, the terminal device obtains the mapping relationship locally, or obtains the mapping relationship from a network device.
In a specific implementation, the transmission parameter may include, for example, a resource location for transmitting uplink control information, or a scrambling sequence used for transmitting uplink control information.
In a specific implementation, the uplink control information may include a scheduling request, that is, the uplink control information may be a scheduling request SR, or the uplink control information may include the SR and other information, or the uplink control information may carry 1-bit redundant information.
By the above implicit manner of indicating the first configuration authorized resource used by the terminal device to send the uplink data to the network device, the network device can determine the first configuration authorized resource used by the terminal device to send the uplink data based on the transmission parameter and the mapping relationship used by the received uplink control information. Therefore, when the configured authorized resource does not correctly receive the uplink data sent by the terminal device, the network device can send downlink control information to the terminal device according to the uplink control information, so as to schedule the terminal device to retransmit the data on the frequency domain resource corresponding to the first configured authorized resource through the downlink control information, thereby reducing the resource overhead of data retransmission.
In the above aspects, the terminal device may explicitly indicate, to the network device, the first configuration grant resource used by the terminal device to send uplink data through the first indication information carried in the uplink control information and used to indicate the first configuration grant resource. That is, the uplink control information may include first indication information, where the first indication information is used to indicate the first configuration grant resource.
In this implementation, the first indication information may include an identifier of a frequency domain resource where the first configuration authorized resource is located, an identifier of the first configuration authorized resource, or information of a configuration parameter of the frequency domain resource. The frequency domain resources referred to herein may include carrier elements or bandwidth portions. The configuration parameter as referred to herein may include a subcarrier spacing, or a symbol length, or a cyclic prefix.
By the above explicit way of indicating the first configuration authorization resource used by the terminal device to send the uplink data to the network device, after receiving the uplink control information, the network device can determine the first configuration authorization resource used by the terminal device to send the uplink data through the first indication information carried by the uplink control information. In this way, when the network device does not correctly receive the uplink data sent by the terminal device on the first configuration authorized resource, the network device can send the downlink control information to the terminal device according to the uplink control information, so as to schedule the terminal device to retransmit the data on the frequency domain resource corresponding to the first configuration authorized resource through the downlink control information, thereby reducing the resource overhead of data retransmission.
In each of the above aspects, when the first configuration grant resource is used for at least two HARQ processes, the sending, by the terminal device, uplink data to the network device using the first configuration grant resource may specifically include: the terminal equipment sends uplink data to the network equipment by using the first configuration authorized resource on the first HARQ process, wherein the first HARQ process is any one of the at least two HARQ processes. Correspondingly, the uplink control information is also used for indicating the first HARQ process used by the terminal device to send uplink data to the network device.
The terminal device may implicitly indicate, to the network device, a first HARQ process of a first configuration grant resource used by the terminal device to send uplink data, through a transmission parameter of the uplink control information. For example, the terminal device obtains a mapping relationship between the transmission parameter of the uplink control information and the HARQ process configured with the authorized resource, and determines the transmission parameter of the uplink control information corresponding to the first HARQ process configured with the authorized resource according to the mapping relationship. In this implementation manner, the terminal device may send the uplink control information to the network device by using the transmission parameter of the uplink control information, so as to implicitly indicate, through the transmission parameter, the uplink data sent by using the first HARQ process of the first configuration grant resource.
Or, the terminal device may explicitly indicate, to the network device, the first HARQ process of the first configuration grant resource used by the terminal device to send uplink data through information carried in the uplink control information. For example, the uplink control information may include first indication information and second indication information. The first indication information is used for indicating a first configuration authorized resource, and the second indication information is used for indicating a first HARQ process of the first configuration authorized resource.
Or, the terminal device may indicate, to the network device, a first HARQ process of a first configuration grant resource used by the terminal device to send uplink data in an explicit and implicit combination manner through a transmission parameter of the uplink control information and information carried by the uplink control information. For example, the terminal device obtains a mapping relationship between the transmission parameter of the uplink control information and the configuration authorized resource, and determines the transmission parameter of the uplink control information according to the mapping relationship. Wherein, one transmission parameter in the mapping relation corresponds to at least one configuration authorization resource. In this implementation manner, the terminal device may send the uplink control information to the network device by using the transmission parameter of the uplink control information, where the uplink control information includes second indication information, and the second indication information is used to indicate the first HARQ process of the first configuration authorized resource.
By the above manner, in a CA scenario, when the terminal device uses one HARQ process configured with the grant resource on one CC to send uplink data, the network device may be instructed, through the uplink control information, of the configuration grant resource used when the terminal device sends the uplink data, and the HARQ process. Therefore, when the configuration authorized resource does not correctly receive the uplink data sent by the terminal device, the network device can schedule the terminal device to retransmit the data of the HARQ process on the frequency domain resource corresponding to the configuration authorized resource according to the uplink control information, thereby ensuring the transmission reliability of the uplink data.
In an eighth aspect, a data transmission method is provided, including:
after acquiring the configuration grant resources for the at least two HARQ processes, the terminal device may send uplink data to the network device using the configuration grant resources on any HARQ process (for short, a first HARQ process) of the at least two HARQ processes, and send uplink control information to the network device, so as to indicate, to the network device, the first HARQ process used by the terminal device to send the uplink data through the uplink control information.
A ninth aspect provides a communication apparatus comprising means for performing the steps of the above eighth aspect.
In a tenth aspect, the present application provides a communication device comprising at least one processor and a memory, the at least one processor being configured to perform the method provided in the eighth aspect above.
In an eleventh aspect, the present application provides a communication device comprising at least one processor configured to perform the method provided in the eighth aspect above and an interface circuit.
In a twelfth aspect, the present application provides a program for performing the method of the above eighth aspect when executed by a processor.
A thirteenth aspect provides a program product, e.g. a computer readable storage medium, comprising the program of the twelfth aspect.
In a fourteenth aspect, a communication device is provided, which is connected to a memory for reading and executing the program stored in the memory to implement the method of the above eighth aspect. The communication device may comprise means, modules or circuits for performing the method provided in the eighth aspect above. The communication device may be a terminal device, or may be a module applied to the terminal device, for example, a chip applied to the terminal device.
It can be seen that, in the above aspects, when the terminal device uses one HARQ process configured with the grant resource to transmit uplink data, the HARQ process used when the terminal device transmits the uplink data may be indicated to the network device through the uplink control information. Therefore, when the configuration authorized resource does not correctly receive the uplink data sent by the terminal device, the network device can schedule the terminal device to retransmit the data of the HARQ process on the frequency domain resource corresponding to the configuration authorized resource according to the uplink control information, thereby ensuring the transmission reliability of the uplink data.
In the above aspects, the terminal device may implicitly indicate, to the network device, a first HARQ process of a configuration grant resource used by the terminal device to send uplink data through a transmission parameter of the uplink control information. For example, the terminal device obtains a mapping relationship between the transmission parameter of the uplink control information and the HARQ process configured with the authorized resource, and determines the transmission parameter of the uplink control information corresponding to the first HARQ process according to the mapping relationship. In this implementation manner, the terminal device may send the uplink control information to the network device by using the transmission parameter of the uplink control information, so as to implicitly indicate the uplink data sent on the first HARQ process through the transmission parameter. It can be understood that, when only one configuration grant resource is configured in the terminal device, the mapping relationship may be a mapping relationship between a transmission parameter and a HARQ process. If at least two configured authorized resources are configured in the terminal device, the mapping relationship may be a mapping relationship between a transmission parameter, a configured authorized resource, and an HARQ process.
In a specific implementation, the terminal device obtains the mapping relationship locally, or obtains the mapping relationship from a network device.
In a specific implementation, the transmission parameter may include, for example, a resource location for transmitting uplink control information, or a scrambling sequence used for transmitting uplink control information.
In a specific implementation, the uplink control information may include a scheduling request, that is, the uplink control information may be a scheduling request SR, or the uplink control information may include the SR and other information, or the uplink control information may carry 1-bit redundant information.
By the above implicit way of indicating the first HARQ process used by the terminal device to send the uplink data to the network device, the network device can determine the first HARQ process used by the terminal device to send the uplink data based on the transmission parameter and the mapping relationship used by the received uplink control information. Therefore, when the configuration authorized resource does not correctly receive the uplink data sent by the terminal device, the network device can send the downlink control information to the terminal device according to the uplink control information, so as to schedule the terminal device to retransmit the data of the first HARQ process on the frequency domain resource corresponding to the configuration authorized resource through the downlink control information, thereby improving the reliability of data transmission.
In the above aspects, the terminal device may explicitly indicate, to the network device, the HARQ process used by the terminal device to send uplink data, through indication information carried in the uplink control information and used for indicating the first HARQ process configured with the grant resource. That is, the uplink control information may include indication information for indicating the first HARQ process configuring the granted resource. It can be understood that, when only one configured granted resource is configured in the terminal device, the indication information may be used to indicate indication information of a first HARQ process configuring the granted resource. If at least two configuration grant resources are configured in the terminal device, the uplink control information may indicate the configuration grant resources and the HARQ process for transmitting uplink data. In a specific implementation, the uplink control information may be indicated by one piece of indication information, or may include two pieces of indication information, for example, first indication information and second indication information, where the first indication information is used to indicate configuration grant resources for transmitting uplink data, and the second indication information is used to indicate a used HARQ process, and the like, and this is not limited.
By the above explicit way of indicating the first HARQ process configured with the grant resource used by the terminal device to send the uplink data to the network device, after receiving the uplink control information, the network device may determine, through the indication information carried by the uplink control information, the first HARQ process configured with the grant resource used by the terminal device to send the uplink data. Therefore, when the network device does not correctly receive the uplink data sent by the terminal device on the configured authorized resource, the network device can send the downlink control information to the terminal device according to the uplink control information, so that the terminal device is scheduled to retransmit the data of the first HARQ process on the frequency domain resource corresponding to the configured authorized resource through the downlink control information, and the reliability of data transmission is improved.
In the above aspects, the terminal device may indicate, to the network device, a first HARQ process configured with grant resources and used by the terminal device to send uplink data in an explicit and implicit combination manner through a transmission parameter of the uplink control information and information carried by the uplink control information. For example, the terminal device obtains a mapping relationship between the transmission parameter of the uplink control information and the configuration authorized resource, and determines the transmission parameter of the uplink control information according to the mapping relationship. Wherein, one transmission parameter in the mapping relation corresponds to at least one configuration authorization resource. In this implementation manner, the terminal device may send uplink control information to the network device by using the transmission parameter of the uplink control information, where the uplink control information includes indication information, and the indication information is used to indicate a first HARQ process for configuring the grant resource.
By the implicit plus explicit method, the first HARQ process of the configuration grant resource used by the terminal device to send the uplink data is indicated to the network device, so that after receiving the uplink control information, the network device can determine the first HARQ process of the configuration grant resource used by the terminal device to send the uplink data according to the transmission parameter used for transmitting the uplink control information and the indication information carried by the uplink control information. Therefore, when the network device does not correctly receive the uplink data sent by the terminal device on the configured authorized resource, the network device can send the downlink control information to the terminal device according to the uplink control information, so that the terminal device is scheduled to retransmit the data of the first HARQ process on the frequency domain resource corresponding to the configured authorized resource through the downlink control information, and the reliability of data transmission is improved.
In a fifteenth aspect, a data transmission method is provided, including:
after configuring at least two configuration authorization resources for the terminal device, the network device may receive uplink control information sent by the terminal device, where the uplink control information is used to indicate, to the network device, a first configuration authorization resource used by the terminal device to send uplink data, and the first configuration authorization resource is any one of the at least two configuration authorization resources. In this way, when the uplink data reception fails, the network device may send downlink control information to the terminal device according to the uplink control information, so as to schedule the terminal device to retransmit data on the frequency domain resource corresponding to the first configuration authorized resource through the downlink control information.
A sixteenth aspect provides a communication device comprising means for performing the steps of the fifteenth aspect above.
In a seventeenth aspect, the present application provides a communications device comprising at least one processor and a memory, the at least one processor configured to perform the method provided by the fifteenth aspect above.

A twenty-first aspect provides a communication device, connected to a memory, for reading and executing a program stored in the memory to implement the method of the above fifteenth aspect. The communication device may comprise means, modules or circuits for performing the method provided in the fifteenth aspect above. The communication device may be a network device, or may be a module applied to the network device, for example, a chip applied to the network device.
In the above aspects, when the first configuration authorized resource used by the terminal device to send uplink data is implicitly indicated by the transmission parameter of the uplink control information, the network device may also send a mapping relationship between the transmission parameter of the uplink control information and the configuration authorized resource to the terminal device, where the transmission parameter corresponds to at least one configuration authorized resource. The transmission parameter may include, for example, a resource location for transmitting uplink control information, or a scrambling sequence used for transmitting uplink control information. The uplink control information may include a scheduling request, that is, the uplink control information may be a scheduling request SR, or the uplink control information may include the SR and other information, or the uplink control information may carry 1-bit redundant information.
In the above aspects, when the terminal device is explicitly indicated to transmit the first configuration grant resource used by the uplink data through the information carried by the uplink control information, the uplink control information may include first indication information, where the first indication information is used to indicate the first configuration grant resource. For example, the first indication information may include an identifier of a frequency domain resource where the first configured authorized resource is located, an identifier of the first configured authorized resource, or information of a configuration parameter of the frequency domain resource. The frequency domain resources referred to herein may include carrier elements or bandwidth portions. The configuration parameter as referred to herein may include a subcarrier spacing, or a symbol length, or a cyclic prefix.
In the above aspects, when the first configuration granted resource is used for at least two HARQ processes, and the uplink data is sent to the network device by the terminal device using the first configuration granted resource on the first HARQ process, the uplink control information is further used to indicate, to the network device, the first HARQ process used by the terminal device to send the uplink data, where the first HARQ process is any one of the at least two HARQ processes.
When the first HARQ process of the first configuration grant resource used by the terminal device to send the uplink data is implicitly indicated by the transmission parameter of the uplink control information, the network device may also send a mapping relationship between the transmission parameter of the uplink control information and the HARQ process of the configuration grant resource to the terminal device.
When the terminal equipment is explicitly indicated to send the first HARQ process of the first configuration authorized resource used by the uplink data through the information carried by the uplink control information, the uplink control information comprises second indication information, and the second indication information is used for indicating the first HARQ process of the first configuration authorized resource.
When the terminal device is instructed to send the first HARQ process of the first configuration grant resource used by the uplink data in an implicit plus explicit manner through the transmission parameter of the uplink control information and the information carried by the uplink control information, the network device may also send the mapping relationship between the transmission parameter of the uplink control information and the configuration grant resource to the terminal device. In this scenario, the uplink control information may include second indication information, where the second indication information is used to indicate a first HARQ process of the first configuration grant resource.
The beneficial effects of the above aspects can be seen in the beneficial effects of the above first to seventh aspects, and are not repeated herein.
In a twenty-second aspect, a data transmission method is provided, including:
after configuring the configuration authorization resources for the at least two HARQ processes for the terminal device, the network device may receive uplink control information sent by the terminal device. The uplink control information is used to indicate, to the network device, a first HARQ process used by the terminal device to send uplink data, where the first HARQ process is any one of the at least two HARQ processes. In this way, when the uplink data reception fails, the network device may send downlink control information to the terminal device according to the uplink control information, so as to schedule the terminal device to retransmit the data in the first HARQ process on the frequency domain resource corresponding to the first configuration authorized resource through the downlink control information.

It can be understood that, when only one configuration grant resource is configured in the terminal device, the mapping relationship may be a mapping relationship between a transmission parameter and a HARQ process. If at least two configured authorized resources are configured in the terminal device, the mapping relationship may be a mapping relationship between a transmission parameter, a configured authorized resource, and an HARQ process.
In the above aspects, when the terminal device is explicitly instructed to transmit the first HARQ process configured with the grant resource used by the uplink data through information carried by the uplink control information, the uplink control information may include instruction information for instructing the first HARQ process configured with the grant resource.
When the first HARQ process of the configuration grant resource used by the terminal device to send the uplink data is indicated by the transmission parameter of the uplink control information and the information carried by the uplink control information in an implicit plus explicit manner, the network device may also send a mapping relationship between the transmission parameter of the uplink control information and the configuration grant resource to the terminal device, where the transmission parameter corresponds to at least one configuration grant resource. At this time, the uplink control information includes indication information for indicating the first HARQ process.
The beneficial effects of the above aspects can be seen from the beneficial effects of the above eighth to fourteenth aspects, which are not repeated herein.

The terminal device is connected to the radio access network device 120 in a wireless manner, and the radio access network device 120 is connected to the core network device 110 in a wireless or wired manner. The core network device 110 and the radio access network device 120 may be separate physical devices, or the function of the core network device 110 and the logical function of the radio access network device 120 may be integrated on the same physical device, or a physical device in which the function of a part of the core network device 110 and the function of a part of the radio access network device 120 are integrated. The terminal equipment may be fixed or mobile. Fig. 1 is a schematic diagram, and the mobile communication system may further include other network devices, such as a wireless relay device and a wireless backhaul device, which are not shown in fig. 1. The embodiments of the present application do not limit the number of the core network device 110, the radio access network device 120, and the terminal device included in the mobile communication system.
Radio access network device 120 is a device in a wireless network, such as a Radio Access Network (RAN) node that accesses a terminal to the wireless network. Currently, some examples of RAN nodes are: a gbb, a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a Base Band Unit (BBU), or a wireless fidelity (Wifi) Access Point (AP), etc. In one network configuration, a network device may include a Centralized Unit (CU) node, or a Distributed Unit (DU) node, or a RAN device including a CU node and a DU node, and so on. The embodiment of the present application does not limit the specific technology and the specific device form adopted by the radio access network device 120. In this embodiment, the radio access network device 120 is simply referred to as a network device, and if no special description is provided, in this embodiment, the network devices are all referred to as the radio access network devices 120. In addition, in the embodiments of the present application, the terms 5G and NR may be equivalent.
A terminal device, also called a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice/data connectivity to a user, for example, a handheld device with a wireless connection function, a vehicle-mounted device, etc. Currently, some examples of terminals are: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (smart security), a wireless terminal in city (smart city), a wireless terminal in home (smart home), and the like.
The radio access network device 120 and the terminal device may be deployed on land, including indoors or outdoors, hand-held or vehicle-mounted; can also be deployed on the water surface; it may also be deployed on airborne airplanes, balloons and satellite vehicles. The application scenarios of the radio access network device 120 and the terminal device are not limited in the embodiments of the present application.
The radio access network device 120 and the terminal device may communicate via a licensed spectrum (licensed spectrum), may communicate via an unlicensed spectrum (unlicensed spectrum), or may communicate via both the licensed spectrum and the unlicensed spectrum. The radio access network device 120 and the terminal device may communicate with each other through a frequency spectrum of 6 gigahertz (GHz) or less, through a frequency spectrum of 6GHz or more, or through both a frequency spectrum of 6GHz or less and a frequency spectrum of 6GHz or more. The spectrum resource used between the radio access network device 120 and the terminal device is not limited in the embodiment of the present application.
Taking 5G mobile communication system as an example, the 5G mobile communication system introduces the concept of periodically configuring granted resource (CG). After the network device configures the CG for the terminal device and activates the terminal device to use the CG, the terminal device may directly use the CG to transmit the upstream data to the network device. Currently, in a 5G mobile communication system, both semi-persistent scheduling (SPS) resources and grant free (grant free) resources are configured grant resources. The grant free resource is referred to as a first Type of configuration granted resource (configured grant Type 1), and the uplink SPS resource is referred to as a second Type of configuration granted resource (configured grant Type 2).
For the first type of configuration authorized resource, the network device may configure the first type of configuration authorized resource to the terminal device by sending configuration information of the first type of configuration authorized resource to the terminal device. Wherein, the configuration information may include: the first type of configuration grants the location (e.g., time-frequency location), size, periodicity, etc. of the resource. Through the configuration information, the terminal device can be configured and activated to transmit uplink data by using the first type of configuration authorization resource. Optionally, the configuration information may further include a Modulation and Coding Scheme (MCS) matched with the first type of configuration authorized resource, so that when the terminal device uses the first type of configuration authorized resource to send uplink data, the terminal device needs to perform coding and modulation processing on the uplink data by using the MCS matched with the first type of configuration authorized resource. In a specific implementation, the network device may send configuration information of the first type of configuration authorized resource to the terminal device through Radio Resource Control (RRC) signaling, which is not limited herein. For example, RRC signaling may be provided with a pre-configured configuration authorization information element field through which the above-mentioned configuration information may be carried.
For the second type of configuration authorized resource, the network device may configure the second type of configuration authorized resource to the terminal device by sending configuration information of the second type of configuration authorized resource to the terminal device. Wherein, the configuration information may include: the second type of configuration grants a periodicity of the resource. Through the configuration information, the terminal device can be configured to transmit uplink data by using the configuration authorization resource of the second type. Further, the network device may indicate a location (e.g., a time-frequency location) and a size of the second type of configuration grant resource by sending Downlink Control Information (DCI) to the terminal device. Optionally, the DCI may further include an MCS matching the second type of configuration grant resource. Through the DCI, the terminal device may be activated to transmit uplink data using the second type of configuration grant resource. In a specific implementation, the network device may send configuration information of the second type of configuration authorized resource to the terminal device through RRC signaling, which is not limited herein. For example, RRC signaling may be provided with a pre-configured configuration authorization information element field through which the above-mentioned configuration information may be carried.
The following application documents all take the configuration authorized resource as an example for description, and the configuration authorized resource may be a configuration authorized resource of a first type or a configuration authorized resource of a second type, which is not distinguished in the embodiments of the present application.
Ultra-reliable and low latency communications (URLLC) is an important service in 5G mobile communication systems, and requires very high reliability and very short delay in transmission. When the terminal device uses the configuration authorization resource configured by the network device for the terminal device to send URLLC service data, if the network device does not solve (i.e., does not correctly receive) the URLLC service data and the identifier of the terminal device sent by the terminal device using the configuration authorization resource, the network device cannot know that the terminal device sent uplink data. In this scenario, the network device may not schedule resources for retransmitting data for the terminal device, and cannot meet the requirement of URLLC service on transmission reliability.
Fig. 2 is a schematic diagram of time-frequency resources. As shown in fig. 2, at present, in order to solve the above problem, the terminal device may transmit, to the network device, an uplink Scheduling Request (SR) using a resource allocated by the network device to transmit an SR while transmitting URLLC service data using a configuration grant resource, so as to indicate to the network device that the terminal device has data to transmit through the SR. Therefore, even if the network device does not correctly receive the URLLC service data sent by the terminal device using the configuration authorization resource, the network device still can know that the terminal device has data to send through the SR sent by the terminal device without resolving the identifier of the terminal device. In this scenario, the network device may schedule a resource for retransmitting data for the terminal device, so that the terminal device may retransmit the URLLC service data using the resource scheduled by the network device, thereby ensuring the transmission reliability of the URLLC service.
Carrier Aggregation (CA) is a process of aggregating 2 or more carrier elements (CCs) to support a larger transmission bandwidth. Each carrier element may correspond to one cell, i.e. 1 carrier element is equivalent to 1 cell. In the CA scenario, the network device may configure the terminal device with the above-mentioned configuration authorization resource on multiple CCs.
Fig. 3 is another schematic diagram of time-frequency resources. As shown in fig. 3, it is assumed that the terminal device can use 4 CCs for data transmission, which are CC1, CC2, CC3, and CC4, respectively. The network device configures a configuration authorized resource 1 for the terminal device on the CC1, configures a configuration authorized resource 2 for the terminal device on the CC2, and configures a configuration authorized resource 3 for the terminal device on the CC 3.
Taking the case that the terminal device uses the configuration authorization resource 3 to transmit uplink data, and transmits an SR to the network device in the resource for transmitting the uplink SR, in this scenario, if the network device does not correctly receive the URLLC service data transmitted by the terminal device using the configuration authorization resource 3, and does not know the identifier of the terminal device, the network device can only know that the terminal device has data to transmit through the SR transmitted by the terminal device, and cannot know which CC the terminal device transmits the uplink data through the configuration authorization resource. Therefore, in order to ensure the transmission reliability of the URLLC service, the network device may schedule resources for retransmitting data for the terminal device on each CC of the terminal device, resulting in a large resource overhead.
In view of the foregoing problems, an embodiment of the present application provides a data transmission method, where in a multi-frequency domain resource scenario, when a terminal uses a configuration authorization resource on one of frequency domain resources to send service data, the terminal indicates, to a network device, the configuration authorization resource used when the terminal device sends the service data through Uplink Control Information (UCI). Therefore, when the configured authorized resource does not correctly receive the service data sent by the terminal device, the network device can schedule the terminal device to retransmit the data on the frequency domain resource corresponding to the configured authorized resource according to the UCI. For example, in a CA scenario, when the terminal device uses the configuration authorization resource on one of the CCs to send URLLC service data, the configuration authorization resource used when the terminal device sends URLLC service data may be indicated to the network device through the uplink control information UCI. Therefore, when the configured authorized resource does not correctly receive the URLLC service data sent by the terminal device, the network device may schedule the terminal device to retransmit the data on the CC corresponding to the configured authorized resource according to the UCI. Compared with the prior art that when the network device does not correctly receive the uplink data sent by the terminal device on the configured authorized resources, the network device schedules the terminal device to retransmit the uplink data on all CCs based on the SR, the method provided by the embodiment of the present application can accurately obtain the configured authorized resources used by the terminal device to send the uplink data through the UCI sent by the terminal device, so that the terminal device can be scheduled to retransmit the data on the frequency domain resources corresponding to the correctly configured authorized resources, and the resource overhead of data retransmission is reduced while the transmission reliability of the URLLC service is ensured. Here, the frequency domain resource may be, for example, a CC, a bandwidth part (BWP), or the like. It can be understood that the method includes, but is not limited to, a scenario of transmitting URLLC service data, and the method of the embodiment of the present application may be applied to any scenario of transmitting uplink data through a configuration authorization resource on one CC in a CA scenario, which is not described herein again.
The technical solution of the present application is explained in detail by some embodiments below. The following several embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 4 is a schematic flowchart of a data transmission method according to an embodiment of the present application. As shown in fig. 4, the method may include:
s101, the network equipment configures at least two configuration authorization resources for the terminal equipment.
Accordingly, the terminal device obtains at least two configuration authorization resources.
S102, the terminal equipment uses the first configuration authorization resource to send uplink data to the network equipment.
Wherein the first configuration authorized resource is any one of at least two configuration authorized resources.
S103, the terminal equipment sends the uplink control information to the network equipment.
The uplink control information is used for indicating, to the network device, a first configuration grant resource used by the terminal device to transmit uplink data.
Accordingly, the network device receives the uplink control information.
And S104, when the network equipment fails to receive the uplink data, the network equipment sends downlink control information to the terminal equipment according to the uplink control information.
The downlink control information is used for scheduling the terminal device to retransmit data on the frequency domain resource corresponding to the first configuration authorized resource.
Specifically, in this embodiment, the network device may configure at least two configuration authorization resources for the terminal device. Wherein each of the at least two configured grant resources may be located within a different frequency domain resource. The at least two configuration authorization resources may be the same type of configuration authorization resource or different types of configuration authorization resources.
It is understood that the network device may determine, according to the types of the at least two configuration authorized resources, a manner of configuring the at least two configuration authorized resources for the terminal device. For how the network device configures each type of configuration authorization resource to the terminal device, reference may be made to the foregoing description, which is not described herein again.
It should be noted that, if the types of the at least two configuration authorized resources are the same, the network device may configure the at least two configuration authorized resources to the terminal device by sending a configuration message to the terminal device. The configuration information may carry configuration information of the at least two configuration authorized resources. Alternatively, the network device may configure the at least two configuration authorized resources to the terminal device by sending configuration information of each configuration authorized resource to the terminal device. If the types of the at least two configuration authorized resources are different, the network device may configure the at least two configuration authorized resources to the terminal device by sending configuration information for each type of configuration authorized resource to the terminal device. The configuration information of each type of configuration authorized resource may carry configuration information of the type of configuration authorized resource. Alternatively, the network device may configure the at least two configuration authorized resources to the terminal device by sending configuration information of each configuration authorized resource to the terminal device.
In this embodiment, after the terminal device obtains the at least two configuration authorized resources configured for the terminal device by the network device, when there is uplink data to be sent, the terminal device may use any one of the at least two configuration authorized resources to configure an authorized resource (i.e., a first configuration authorized resource) and send the uplink data to the network device. Correspondingly, the terminal device may further send UCI to the network device to indicate, to the network device, the configuration authorization resource used when the terminal device sends the uplink data. In this way, when the configured authorized resource does not correctly receive the uplink data sent by the terminal device, the network device may send DCI to the terminal device according to the UCI, so as to schedule the terminal device to retransmit data on the frequency domain resource corresponding to the first configured authorized resource through the DCI. Compared with the prior art that when the network device does not correctly receive the uplink data sent by the terminal device on the configured authorized resource, the terminal device is scheduled to retransmit the data on all frequency domain resources based on the SR, the method provided by the embodiment of the present application can accurately obtain the configured authorized resource used by the terminal device to send the uplink data through the UCI sent by the terminal device, so that the terminal device can be scheduled to retransmit the data on the frequency domain resource corresponding to the correctly configured authorized resource, and the resource overhead of data retransmission is reduced while the reliability of data transmission is ensured.
How to indicate the first configuration authorized resource used by the terminal device to send uplink data to the network device through the UCI is described below, which may specifically include the following several ways:
the first mode is as follows: and implicitly indicating a first configuration authorization resource used by the terminal equipment for sending the uplink data to the network equipment through the transmission parameter of the UCI. Wherein, the transmission parameters of the UCI may include: a resource location where the UCI is transmitted, and/or a scrambling sequence used for transmitting the UCI. In this scenario, the UCI may include an SR, that is, the UCI may be the SR, or the UCI may include the SR and other information, or the UCI may carry 1-bit redundant information. Optionally, in this embodiment, the UCI may also carry other uplink control information, which is not limited in this embodiment.
Fig. 5 is a flowchart illustrating another data transmission method according to an embodiment of the present application. As shown in fig. 5, the method further includes:
s201, the terminal equipment acquires the mapping relation between the transmission parameters of the UCI and the configuration authorization resources.
S202, the terminal equipment determines the transmission parameters of the UCI according to the mapping relation.
In this embodiment, a mapping relationship exists between the transmission parameters of the UCI and the configuration grant resources. In the mapping relationship, one transmission parameter may correspond to one configuration authorized resource, or may correspond to a plurality of configuration authorized resources, which may be specifically determined according to the configuration of the mobile communication system. It is to be understood that, in some embodiments, the mapping relationship may also be referred to as a corresponding relationship, which is not limited in the embodiments of the present application.
Optionally, the network device and the terminal device may preset a mapping relationship between the transmission parameter of the UCI and the configuration authorization resource, and in this implementation, the terminal device may obtain the mapping relationship locally. Optionally, the terminal device may further obtain the mapping relationship from the network device by receiving the mapping relationship between the transmission parameter of the UCI and the configuration authorization resource sent by the network device. In specific implementation, the network device may send the mapping relationship to the terminal device through RRC signaling or DCI.
Therefore, when the terminal device uses the first configuration authorized resource to send the uplink data, the terminal device may obtain the mapping relationship, and based on the mapping relationship and the first configuration authorized resource, search the transmission parameter corresponding to the first configuration authorized resource from the mapping relationship, and send the UCI to the network device by using the transmission parameter as the transmission parameter for transmitting the UCI this time. Correspondingly, the network device may blindly detect the UCI sent by the terminal device by using all the transmission parameters in the mapping relationship, and determine the first configuration authorization resource used by the terminal device to send the uplink data according to the transmission parameters and the mapping relationship used by the blindly detected UCI. In this way, when the configured authorized resource does not correctly receive the uplink data sent by the terminal device, the network device may send DCI to the terminal device according to the UCI, so as to schedule the terminal device to retransmit data on the frequency domain resource corresponding to the first configured authorized resource through the DCI. Compared with the prior art that when the network device does not correctly receive the uplink data sent by the terminal device on the configured authorized resource, the terminal device is scheduled to retransmit the data on all frequency domain resources based on the SR, the method provided by the embodiment of the present application can accurately obtain the configured authorized resource used by the terminal device to send the uplink data through the UCI sent by the terminal device, so that the terminal device can be scheduled to retransmit the data on the frequency domain resource corresponding to the correctly configured authorized resource, and the resource overhead of data retransmission is reduced while the reliability of data transmission is ensured.
Taking the transmission parameter as the resource location for transmitting the UCI as an example, in the mapping relationship, one resource location for transmitting the UCI may correspond to one configured authorized resource or may correspond to a plurality of configured authorized resources. When a resource location for transmitting UCI corresponds to multiple configuration grant resources, the number of the configuration grant resources corresponding to the resource location and the frequency resource where the configuration grant resources are located may be determined specifically according to the system configuration. For example, the system uplink bandwidth may be divided into a plurality of frequency domain resource regions, and a resource location where UCI may be transmitted is reserved in each frequency domain region. In this scenario, the resource location of the UCI may correspond to one or more configuration grant resources located within the frequency domain region.
It can be understood that the resource locations for transmitting UCI may be periodically distributed in time, and the period may be the same as or different from a period for configuring the grant resource corresponding to the resource location, which is not limited in this embodiment of the present application. For example, the resource location for transmitting UCI may be a fixed time-frequency resource location in each time unit. The time unit may be, for example, a slot (slot), a mini-slot (mini-slot), a subframe, or the like.
This is schematically illustrated below by a specific example. Fig. 6 is a schematic diagram of a time-frequency resource provided in an embodiment of the present application. Fig. 7 is another schematic diagram of time-frequency resources provided in the embodiment of the present application. As shown in fig. 6 and 7, for example, a terminal device may use 4 CCs for data transmission, where the 4 CCs are CC1, CC2, CC3, and CC4, respectively. The network device configures a configuration authorized resource 1 for the terminal device on the CC1, configures a configuration authorized resource 2 for the terminal device on the CC2, and configures a configuration authorized resource 3 for the terminal device on the CC 3.
As shown in fig. 6, when a resource location for transmitting UCI in the mapping relationship corresponds to a configuration authorized resource, the network device may reserve a resource location of UCI corresponding to each configuration authorized resource. In this scenario, when the terminal device uses any one of the above-mentioned configuration authorized resources to send uplink data, the terminal device may send UCI to the network device at a resource location of UCI corresponding to the configuration authorized resource, so as to indicate, to the network device, the configuration authorized resource used by the terminal device to send uplink data.
Taking the example that the terminal device uses the configured authorized resource 1 on the CC1 to send the uplink data, the terminal device may send UCI to the network device at the resource location of UCI corresponding to the configured authorized resource 1. Accordingly, the network device may blindly detect the UCI sent by the terminal device in the resource positions of all UCI in the mapping relationship. When the network device blindly detects the UCI sent by the terminal device at the resource position of the UCI corresponding to the configuration authorized resource 1, the network device may obtain the configuration authorized resource 1 used by the terminal device to send the uplink data based on the resource position of the UCI corresponding to the configuration authorized resource 1 and the mapping relationship. In this way, when the configuration authorized resource 1 does not correctly receive the uplink data sent by the terminal device, the network device may send DCI to the terminal device according to the UCI, so as to schedule the terminal device to retransmit data on the CC corresponding to the configuration authorized resource 1 through the DCI. Compared with the prior art that when the network device does not correctly receive the uplink data sent by the terminal device on the configured authorized resource, the terminal device is scheduled to retransmit the data on all frequency domain resources based on the SR, the method provided by the embodiment of the present application can accurately obtain the configured authorized resource used by the terminal device to send the uplink data through the UCI sent by the terminal device, so that the terminal device can be scheduled to retransmit the data on the frequency domain resource corresponding to the correctly configured authorized resource, and the resource overhead of data retransmission is reduced while the reliability of data transmission is ensured.
As shown in fig. 7, when a resource location for transmitting UCI in the mapping relationship corresponds to multiple configured authorized resources, taking, for example, the configured authorized resource on CC1 and the configured authorized resource on CC2 correspond to a resource location for transmitting UCI, and the configured authorized resource on CC3 corresponds to a resource location for transmitting UCI, the network device may reserve resource locations for transmitting UCI corresponding to the configured authorized resource on CC1 and the configured authorized resource on CC2, and resource locations for transmitting UCI corresponding to the configured authorized resource on CC 3. In this scenario, when the terminal device uses any one of the above-mentioned configuration authorized resources to send uplink data, the terminal device may send UCI to the network device at a resource location of UCI corresponding to the configuration authorized resource, so as to indicate, to the network device, the configuration authorized resource used by the terminal device to send uplink data.
Taking the example that the terminal device uses the configured authorized resource 1 on the CC1 to send the uplink data, the terminal device may send UCI to the network device at the resource location of UCI corresponding to the configured authorized resource 1 and the configured authorized resource 2. Accordingly, the network device may blindly detect the UCI sent by the terminal device in the resource positions of all UCI in the mapping relationship. When the network device blindly detects the UCI sent by the terminal device at the resource positions of the UCI corresponding to the configuration authorized resource 1 and the configuration authorized resource 2, the network device may know that one of the configuration authorized resource 1 and the configuration authorized resource 2 is used for sending uplink data by the terminal device based on the resource positions of the UCI corresponding to the configuration authorized resource 1 and the configuration authorized resource 2 and the mapping relationship. Thus, when the configuration authorized resource 1 does not correctly receive the uplink data sent by the terminal device, the network device may send DCI to the terminal device according to the UCI, so as to schedule the terminal device through the DCI to retransmit data on the CC corresponding to the configuration authorized resource 1 and the CC corresponding to the configuration authorized resource 2. Compared with the prior art that when the network device does not correctly receive the uplink data sent by the terminal device on the configured authorized resources, the terminal device is scheduled to retransmit the uplink data on all frequency domain resources based on the SR, the method provided by the embodiment of the present application can indicate the configured authorized resources used by the terminal device to send the uplink data in a coarse granularity in a manner that resource positions used by UCI sent by the terminal device correspond to a plurality of configured authorized resources, so that the terminal device can be scheduled to retransmit the data on the frequency domain resources corresponding to part of the configured authorized resources, and while ensuring the reliability of data transmission, the resource overhead of data retransmission is reduced, and the resource overhead of UCI is reduced.
Taking the scrambling sequence used by the transmission parameter for transmitting the UCI as an example, in the above mapping relationship, the scrambling sequence used by one transmission UCI may correspond to one configured authorized resource or may correspond to a plurality of configured authorized resources. When a scrambling sequence used for transmitting UCI corresponds to a plurality of configuration grant resources, the number of the configuration grant resources corresponding to the scrambling sequence and the frequency resource where the configuration grant resources are located may be specifically determined according to the system configuration. It can be understood that, in this scenario, the network device may reserve a time-frequency resource for transmitting UCI. The time-frequency resources for transmitting UCI corresponding to each terminal device may be different. The reserved resource locations for sending the UCI may be periodically distributed in time, and the period may be the same as or different from a period for configuring the authorized resource corresponding to the resource location, which is not limited in this embodiment of the present application.
Taking an example that a scrambling sequence used for transmitting UCI corresponds to a configured grant resource, the mapping relationship may be as shown in table 1 below:
TABLE 1
Figure BDA0001684275010000141
Taking the example that the terminal device uses the configuration authorized resource 1 to send the uplink data, the terminal device may scramble the UCI in the scrambling sequence 1 used by the UCI corresponding to the configuration authorized resource 1. Accordingly, the network device may blindly detect the UCI sent by the terminal device by using the scrambling sequences used by all transmission UCI covered by the mapping relationship. When the network device blindly detects the UCI by using the scrambling sequence used for transmitting the UCI corresponding to the configuration authorized resource 1, the network device may obtain the configuration authorized resource 1 used for the terminal device to transmit the uplink data based on the scrambling sequence used for the UCI corresponding to the configuration authorized resource 1 and the mapping relationship. In this way, when the configuration authorized resource 1 does not correctly receive the uplink data sent by the terminal device, the network device may send DCI to the terminal device according to the UCI, so as to schedule the terminal device to retransmit data on the frequency domain resource corresponding to the configuration authorized resource 1 through the DCI. Compared with the prior art that when the network device does not correctly receive the uplink data sent by the terminal device on the configured authorized resource, the terminal device is scheduled to retransmit the data on all frequency domain resources based on the SR, the method provided by the embodiment of the present application can accurately obtain the configured authorized resource used by the terminal device to send the uplink data through the UCI sent by the terminal device, so that the terminal device can be scheduled to retransmit the data on the frequency domain resource corresponding to the correctly configured authorized resource, and the resource overhead of data retransmission is reduced while the reliability of data transmission is ensured.
Taking the transmission parameters including the resource location for transmitting the UCI and the scrambling sequence used for transmitting the UCI as an example, in the mapping relationship, one transmission parameter may correspond to one configured authorized resource or may correspond to a plurality of configured authorized resources.
In this scenario, when the terminal device uses a configuration authorization resource to send uplink data, the terminal device may scramble UCI using a scrambling sequence used by UCI corresponding to the configuration authorization resource, and send the scrambled UCI to the network device at a resource location where UCI is transmitted corresponding to the configuration authorization resource. Correspondingly, the network device may blindly detect the UCI sent by the terminal device by using all the transmission parameters in the mapping relationship, and determine the first configuration authorization resource used by the terminal device to send the uplink data according to the transmission parameters and the mapping relationship used by the blindly detected UCI. In this way, when the configured authorized resource does not correctly receive the uplink data sent by the terminal device, the network device may send DCI to the terminal device according to the UCI, so as to schedule the terminal device to retransmit data on the frequency domain resource corresponding to the first configured authorized resource through the DCI. Compared with the prior art that when the network device does not correctly receive the uplink data sent by the terminal device on the configured authorized resource, the terminal device is scheduled to retransmit the data on all frequency domain resources based on the SR, the method provided by the embodiment of the present application can accurately obtain the configured authorized resource used by the terminal device to send the uplink data through the UCI sent by the terminal device, so that the terminal device can be scheduled to retransmit the data on the frequency domain resource corresponding to the correctly configured authorized resource, and the resource overhead of data retransmission is reduced while the reliability of data transmission is ensured.
The second mode is as follows: and explicitly indicating the first configuration authorized resource used by the terminal equipment to the network equipment through first indication information which is carried by the UCI and used for indicating the first configuration authorized resource. It can be understood that, in this scenario, the network device may reserve a time-frequency resource for transmitting UCI. The reserved resource locations for sending the UCI may be periodically distributed in time, and the period may be the same as or different from a period for configuring the authorized resource corresponding to the resource location, which is not limited in this embodiment of the present application.
In this scenario, when the terminal device uses the first configuration grant resource to send uplink data, the terminal device may send, to the network device, the UCI carrying the first indication information for indicating the first configuration grant resource. Correspondingly, after receiving the UCI, the network device may determine, through the first indication information carried by the UCI, the first configuration authorization resource used by the terminal device to send the uplink data. In this way, when the network device does not correctly receive the uplink data sent by the terminal device on the first configuration authorized resource, the network device may send DCI to the terminal device according to the UCI, so as to schedule the terminal device to retransmit data on the frequency domain resource corresponding to the first configuration authorized resource through the DCI. Compared with the prior art that when the network device does not correctly receive the uplink data sent by the terminal device on the configured authorized resource, the terminal device is scheduled to retransmit the data on all frequency domain resources based on the SR, the method provided by the embodiment of the present application can accurately obtain the configured authorized resource used by the terminal device to send the uplink data through the UCI sent by the terminal device, so that the terminal device can be scheduled to retransmit the data on the frequency domain resource corresponding to the correctly configured authorized resource, and the resource overhead of data retransmission is reduced while the reliability of data transmission is ensured.
Wherein, the first indication information may include at least one of the following: an identifier of the frequency domain resource (e.g., an identifier of the CC, an identifier of the BWP, etc.) where the first configuration granted resource is located, an identifier of the first configuration granted resource (e.g., an index of the first configuration granted resource), and information of configuration parameters of the frequency domain resource. The configuration parameters referred to herein may include at least one of: subcarrier spacing, symbol length, cyclic prefix, etc. In some embodiments, the above configuration parameters may also be referred to as numerology. Therefore, the information of the configuration parameter of the frequency domain resource may also be an identifier of numerology, for example, an index of numerology.
When the first indication information may include at least one of an identifier of a frequency domain resource where the first configured authorized resource is located, an identifier of the first configured authorized resource, and information of a configuration parameter of the frequency domain resource, the first indication information may be provided with a domain of each item. The number of bits occupied by the domain of each entry may be specifically determined according to the system configuration. Alternatively, the first indication information may indicate each content item through a bitmap. In this scenario, the number of combinations may be determined according to the system configuration, and the number of bits occupied by the first indication information may be determined based on the number.
With 16 cells in total, each cell corresponds to one CC, each cell includes 4 BWPs, and each BWP is configured with a configuration authorized resource of 4 different configuration authorized resource identifications (for example, configuration authorized resource indexes), the first indication information may indicate the first configuration authorized resource through at least one of an identification of a frequency domain resource where the first configuration authorized resource is located, an identification of the first configuration authorized resource, and/or information of a configuration parameter of the frequency domain resource.
It is assumed that the first indication information indicates the first configured granted resource through an identifier of a frequency domain resource where the first configured granted resource is located and information of a configuration parameter of the frequency domain resource. The first indication information may include fields as shown in table 2 below, i.e., the number of bits occupied by the first indication information may be 8 bits.
TABLE 2
First indication information Number of bits
CC identification 4 bits
BWP identification 2 bits
Configuring authorized resource identification 2 bits
In another implementation manner, the first indication information may further indicate, in a bitmap manner, an identifier of a frequency domain resource where the first configuration authorized resource is located, and information of a configuration parameter of the frequency domain resource. For this example, there are 16 CCs, each CC has 4 BWPs, each BWP has 4 configuration authorized resources with different configuration authorized resource identifiers, the number of combinations is the product of 16 and 4, and is 256, and the number of bits occupied by the first indication information may be the number of bits

Optionally, the network device and the terminal device may preset a format of the first indication information. Optionally, the terminal device may further obtain the format of the first indication information from the network device by receiving the format of the first indication information sent by the network device. In a specific implementation, the network device may send the format of the first indication information to the terminal device through RRC signaling or DCI.
It should be noted that, although the foregoing examples describe how the UCI indicates, to the network device, the first configuration grant resource used by the terminal device to send uplink data in an implicit indication manner and a display indication manner, respectively. However, it can be understood by those skilled in the art that a combination of the above two manners may also be adopted to instruct the terminal device to transmit the first configuration grant resource used by the uplink data. For example, the first configuration authorization resource used by the terminal device to send uplink data may be indicated by the first indication information carried by the UCI and a scrambling sequence combination manner used when the UCI is transmitted, and the like, which is not described in detail herein.
In the data transmission method provided in the embodiment of the present application, in a CA scenario, when a terminal device uses a configuration authorization resource on one CC to send uplink data, the configuration authorization resource used when the terminal device sends the uplink data may be indicated to a network device through a UCI. Therefore, when the configured authorized resource does not correctly receive the uplink data sent by the terminal device, the network device can schedule the terminal device to retransmit the data on the frequency domain resource corresponding to the configured authorized resource according to the UCI. Compared with the prior art that when the network device does not correctly receive the uplink data sent by the terminal device on the configured authorized resource, the terminal device is scheduled to retransmit the data on all frequency domain resources based on the SR, the method provided by the embodiment of the present application can accurately obtain the configured authorized resource used by the terminal device to send the uplink data through the UCI sent by the terminal device, so that the terminal device can be scheduled to retransmit the data on the frequency domain resource corresponding to the correctly configured authorized resource, and the resource overhead of data retransmission is reduced while the reliability of data transmission is ensured.
Fig. 8 is a schematic diagram of another time-frequency resource provided in the embodiment of the present application. As shown in fig. 8, as in the foregoing embodiment, one configuration grant resource corresponds to one frequency domain resource. Optionally, in some embodiments, a time-frequency resource with grant resources configured at different positions may be used to transmit data of different hybrid automatic repeat request (HARQ) processes. Taking the example that the first configuration authorized resource corresponds to at least two HARQ processes, the S102 may specifically include: the terminal equipment sends uplink data to the network equipment by using the first configuration authorized resource on the first HARQ process, wherein the first HARQ process is any one of the at least two HARQ processes. In this scenario, the UCI is further configured to indicate, to the network device, a first HARQ process used by the terminal device to send uplink data.
In this way, when the network device does not correctly receive the uplink data sent by the terminal device on the first configuration authorized resource, the network device may send DCI to the terminal device according to the UCI, so as to schedule the terminal device through the DCI to retransmit the data in the first HARQ process on the frequency domain resource corresponding to the first configuration authorized resource. By the method, when the network equipment does not correctly receive the data on one HARQ process sent by the terminal equipment, the terminal equipment can be scheduled to retransmit the data on the HARQ process, so that the situation that the network equipment schedules the terminal equipment to retransmit the data on other HARQ processes due to the fact that the terminal equipment cannot determine which HARQ process on which configuration authorized resource is sent by the terminal equipment through the SR when the network equipment does not receive the data sent by the terminal equipment on the configuration authorized resource is avoided, and the terminal equipment cannot retransmit the data on the correct HARQ process, and the data transmission reliability is improved.
How to indicate the first HARQ process used by the terminal device to send uplink data to the network device through the UCI is described below, which may specifically include the following several ways:
the first mode is as follows: and implicitly indicating a first HARQ process used by the terminal equipment for sending uplink data to the network equipment through the transmission parameters of the UCI. Wherein, the transmission parameters of the UCI may include: a resource location where the UCI is transmitted, and/or a scrambling sequence used for transmitting the UCI. In this scenario, the UCI may include the SR, that is, the UCI may be the SR, or the UCI may include the SR and other information, or the UCI may carry 1-bit redundant information. Optionally, in this embodiment, the UCI may also carry other uplink control information, which is not limited in this embodiment.
Fig. 9 is a flowchart illustrating another data transmission method according to an embodiment of the present application. As shown in fig. 9, the method further includes:
s301, the terminal equipment obtains the mapping relation between the transmission parameters of the uplink control information and the HARQ process of the configuration authorization resource.
S302, the terminal equipment determines the transmission parameters of the UCI according to the mapping relation.
In this embodiment, a mapping relationship exists between the transmission parameter of the UCI and the HARQ process configuring the grant resource. In the mapping relationship, one transmission parameter may correspond to one HARQ process configuring the authorized resource, and may specifically be determined according to the configuration of the mobile communication system. It is to be understood that, in some embodiments, the mapping relationship may also be referred to as a corresponding relationship, which is not limited in the embodiments of the present application.
Optionally, the network device and the terminal device may preset a mapping relationship between the transmission parameter of the UCI and the HARQ process configured with the authorized resource, and in this implementation, the terminal device may obtain the mapping relationship locally. Optionally, the terminal device may further obtain the mapping relationship from the network device by receiving the mapping relationship between the transmission parameter of the UCI sent by the network device and the HARQ process configured with the authorized resource. In specific implementation, the network device may send the mapping relationship to the terminal device through RRC signaling or DCI.
Therefore, when the terminal device uses the first HARQ process of the first configuration authorized resource to send uplink data, the terminal device may obtain the mapping relationship, and based on the mapping relationship and the first HARQ process of the first configuration authorized resource, search for a transmission parameter corresponding to the first HARQ process of the first configuration authorized resource from the mapping relationship, and send the UCI to the network device by using the transmission parameter as a transmission parameter for transmitting UCI this time. Correspondingly, the network device may blindly detect the UCI sent by the terminal device by using all the transmission parameters in the mapping relationship, and determine the first HARQ process of the first configuration grant resource used by the terminal device to send the uplink data according to the transmission parameters and the mapping relationship used by the blindly detected UCI. Therefore, when the configured authorized resource does not correctly receive the uplink data sent by the terminal device, the network device can send the DCI to the terminal device according to the UCI, so as to schedule the terminal device through the DCI to retransmit the first HARQ process data on the frequency domain resource corresponding to the first configured authorized resource, thereby improving the reliability of data transmission.
The description of the mapping relationship between the transmission parameter and the HARQ process configured with the authorized resource may specifically refer to the mapping relationship between the transmission parameter and the HARQ process configured with the authorized resource, which is similar to the implementation principle, and is not repeated here.
The second mode is as follows: the UCI carries first indication information used for indicating first configuration authorization resources and second indication information used for indicating a first HARQ process of the first configuration authorization resources, and the first HARQ process of the first configuration authorization resources used for sending uplink data to the terminal equipment is indicated to the network equipment in an explicit mode. The second indication information may include, for example, an identifier of the first HARQ process (e.g., an index of the first HARQ process).
It can be understood that, in this scenario, the network device may reserve a time-frequency resource for transmitting UCI. The reserved resource locations for sending the UCI may be periodically distributed in time, and the period may be the same as or different from a period for configuring the authorized resource corresponding to the resource location, which is not limited in this embodiment of the present application.
In this scenario, when the terminal device uses the first HARQ process of the first configuration authorized resource to send uplink data, the terminal device may send, to the network device, first indication information carrying information for indicating the first configuration authorized resource and UCI of the first HARQ process for indicating the first configuration authorized resource. Correspondingly, after receiving the UCI, the network device may determine, through the first indication information and the second indication information carried by the UCI, a first HARQ process of a first configuration grant resource used by the terminal device for sending uplink data. Therefore, when the network device does not correctly receive the uplink data sent by the terminal device on the first configuration authorized resource, the network device can send the DCI to the terminal device according to the UCI, so that the terminal device is scheduled by the DCI to retransmit the data of the first HARQ process on the frequency domain resource corresponding to the first configuration authorized resource, thereby improving the reliability of data transmission.
For the description of the first indication information, reference may be made to the description of the first indication information in the foregoing embodiment, which is not described herein again.
In addition, the first indication information and the second indication information may be present in the UCI independently from each other or may be present in the UCI in a combined manner. When the first indication information and the second indication information exist in the UCI in a combined manner, the number of each combination may be determined according to the system configuration, and the number of bits occupied by the UCI may be determined based on the number.
Continuing to use the network device to have 16 cells in total next, each cell corresponding to one CC, each cell including 4 BWPs, each BWP being configured with 4 configuration authorized resources identified by different configuration authorized resources, wherein one configuration authorized resource corresponds to 3 HARQ processes, the number of each combination is 16 times the product of 4, 4 and 3, and is 768 in total, and the number of bits occupied by the UCI may be equal to the number of bits occupied by the UCI

It can be understood that, although the above examples describe how the UCI indicates, to the network device, the first HARQ process of the first configuration grant resource used by the terminal device to send uplink data, in an implicit indication manner and a display indication manner, respectively. However, it can be understood by those skilled in the art that a combination of the above two manners may also be adopted to instruct the terminal device to transmit the first configuration grant resource used by the uplink data. For example, the first indication information and the second indication information carried by the UCI, and the first HARQ process of the first configuration grant resource used by the terminal device to send the uplink data may be indicated in a manner of combining scrambling sequences used in UCI transmission, and the like, which are not described in detail herein.
The third mode is as follows: and implicitly indicating a first configuration authorization resource used by the terminal equipment for sending the uplink data to the network equipment through the transmission parameter of the UCI. And explicitly indicating the first HARQ process used by the terminal equipment for sending the uplink data to the network equipment through second indication information which is carried by the UCI and used for indicating the first HARQ process. Namely, the first HARQ process of the first configuration grant resource used by the terminal device to send the uplink data is indicated in a manner of combining implicit and explicit.
In this embodiment, a mapping relationship exists between the transmission parameters of the UCI and the configuration grant resources. In the mapping relationship, one transmission parameter may correspond to one configuration authorized resource, or may correspond to a plurality of configuration authorized resources, which may be specifically determined according to the configuration of the mobile communication system. It is to be understood that, in some embodiments, the mapping relationship may also be referred to as a corresponding relationship, which is not limited in the embodiments of the present application.
Optionally, the network device and the terminal device may preset a mapping relationship between the transmission parameter of the UCI and the configuration authorization resource, and in this implementation, the terminal device may obtain the mapping relationship locally. Optionally, the terminal device may further obtain the mapping relationship from the network device by receiving the mapping relationship between the transmission parameter of the UCI and the configuration authorization resource sent by the network device. In specific implementation, the network device may send the mapping relationship to the terminal device through RRC signaling or DCI.
Therefore, when the terminal device uses the first HARQ process of the first configuration authorized resource to send uplink data, the terminal device may obtain the mapping relationship, search for a transmission parameter corresponding to the first configuration authorized resource from the mapping relationship based on the mapping relationship and the first configuration authorized resource, use the transmission parameter as a transmission parameter for transmitting UCI this time, and send UCI carrying the second indication information to the network device. Correspondingly, the network device may blindly detect the UCI sent by the terminal device by using all transmission parameters in the mapping relationship, determine a first configuration authorized resource used by the terminal device to send uplink data according to the transmission parameter and the mapping relationship used by the blindly detected UCI, and determine a first HARQ process used according to second indication information carried by the UCI. Therefore, when the configured authorized resource does not correctly receive the uplink data sent by the terminal device, the network device can send the DCI to the terminal device according to the UCI, so as to schedule the terminal device through the DCI to retransmit the data of the first HARQ process on the frequency domain resource corresponding to the first configured authorized resource, thereby improving the reliability of data transmission.
For the description that the mapping relationship exists between the transmission parameter of the UCI and the configuration authorization resource and the second indication information, reference may be made to the foregoing embodiments, which are not described herein again.
It should be noted that the above embodiment may also be applicable to a scenario where the network device configures one configuration authorized resource for the terminal device, and the configuration authorized resource corresponds to at least two HARQ processes, and the implementation principle and technical effect are similar to those described above, and details are not described here again. That is to say, this embodiment may exist as a single embodiment, and is not necessarily attached to the foregoing embodiment in which the network device configures at least two configuration authorized resources for the terminal device.
In the data transmission method provided in the embodiment of the present application, in a CA scenario, when a terminal device uses one HARQ process configured with an authorized resource on one CC to transmit uplink data, the configured authorized resource used when the terminal device transmits the uplink data and the HARQ process may be indicated to a network device through UCI. Therefore, when the configuration authorized resource does not correctly receive the uplink data sent by the terminal device, the network device can schedule the terminal device to retransmit the data of the HARQ process on the frequency domain resource corresponding to the configuration authorized resource according to the UCI, thereby ensuring the transmission reliability of the uplink data.
