Description

Retransmission method, device and equipment of uplink data

Technical Field

The present invention relates to communications technologies, and in particular, to a method, an apparatus, and a device for retransmitting uplink data.

Background

For a User Equipment (UE) in a connected state, when performing uplink data transmission and downlink data transmission, a network resource used by the UE is typically dynamically scheduled by a base station. In order to better serve periodic traffic, the concept of pre-Configured resources, which can be divided into Semi-persistent scheduling (SPS) resources and Configured Grant (CG) resources, is introduced in the fifth Generation (5th-Generation, abbreviated as 5G) mobile communication technology system. The SPS resource is used for downlink data transmission, and the CG resource is used for uplink data transmission. For the CG resource, it is usually a resource configured in a periodically occurring manner, and the configuration information of the CG resource may include a frequency hopping pattern, a modulation coding level, a resource allocation, and the like.

When uplink data transmission is performed through CG resources, a concept of configuring a granted Grant timer (CG timer for short) is introduced into a New Radio (NR) system, and a concept of configuring a granted Grant retransmission timer (CG retransmission timer for short) is introduced into an NR-U system. Taking a CG timer as an example, a base station configures a plurality of CG resources for a UE in advance, where the CG resources are used for transmitting uplink data, and sets a corresponding CG timer for a Hybrid Automatic Repeat-reQuest (HARQ) process associated when transmitting the uplink data, and when the CG timer corresponding to a certain HARQ process is running, the UE does not perform data transmission on other CG resources, so that other CG resources are in an idle state. When other CG resources are in an idle state and the CG resources are dedicated resources of the UE, the other CG resources are always in an idle state, which results in a low utilization rate of the CG resources, and for the UE, only one CG resource is used to transmit the upload data, which may result in a low decoding success rate of the receiving end base station of the uplink data due to a failure in uplink data transmission.

Therefore, in the process of performing uplink data transmission on CG resources, how to improve the decoding success rate of the uplink data receiving end on the basis of improving the utilization rate of CG resources is a problem to be solved by those skilled in the art.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "first," "second," and the like in the description and in the claims, and in the drawings, of the embodiments of the application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The embodiments of the present application are applied to a communication system, such as a fifth generation (5G) communication system or other systems that may appear in the future, and some terms in the present application are explained below to facilitate understanding by those skilled in the art. It should be noted that, when the scheme of the embodiment of the present application is applied to a 5G system or other systems that may appear in the future, names of the network device and the terminal device may change, but this does not affect implementation of the scheme of the embodiment of the present application.

Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application, where the communication system may include a network device and at least one terminal device. For example, please refer to fig. 1, taking a communication system including a network device and a terminal device as an example, before uplink data transmission is performed by the terminal device, the network device may allocate a plurality of CG resources to the terminal device in advance, where the CG resources are used for the terminal device to transmit uplink data, and may set a corresponding CG timer for an associated HARQ process when transmitting uplink data, and when the CG timer corresponding to a certain HARQ process is running, the UE may not perform uplink data transmission on other CG resources, so that other CG resources may be in an idle state. Especially, when the plurality of CG resources are dedicated CG resources of the UE, the other CG resources are always in an idle state, which results in a low utilization rate of the CG resources, and for the UE, only one CG resource is used to transmit the uplink data, which may result in a low decoding success rate of the receiving end base station of the uplink data due to a failure in uplink data transmission.

It can be seen that, in the prior art, in the process of performing uplink data transmission on CG resources, the utilization rate of CG resources is low, and the reason that the decoding success rate of the uplink data receiving end is low is that: when a CG timer corresponding to a certain HARQ process is running, the UE does not perform data transmission through other CG resources, so that the other CG resources may be in an idle state, and because the other CG resources are dedicated resources of the UE, even if the other CG resources are in the idle state, the other UE cannot use the other CG resources to perform uplink data transmission, so that the utilization rate of the CG resources is low, and the UE transmits upload data only through a certain CG resource, so that an uplink data receiving end can decode only through uplink data received once, thereby resulting in a low decoding success rate of the uplink data receiving end.

In order to improve the utilization rate of CG resources and improve the decoding success rate of an uplink data receiving end, an embodiment of the present application provides a method for retransmitting uplink data, please refer to fig. 2, where fig. 2 is a schematic flow diagram of a method for retransmitting uplink data provided in an embodiment of the present application, and the method includes: s201, a terminal device receives a resource configuration message from a network device, and unlike the prior art, the resource configuration message in this embodiment includes not only information of configuring an authorized resource, but also first indication information, where the first indication information is used to indicate whether to allow retransmission of first uplink data on a target configuration authorized resource associated with a target process in the configured authorized resource when a timer corresponding to the target process runs during transmission of the first uplink data; s202, if the first indication information indicates that the first uplink data retransmission is allowed to be performed on the target configuration authorized resource, the terminal device performs the first uplink data retransmission on the target configuration authorized resource associated with the target process until a preset condition is met. Therefore, in the embodiment of the application, during the running period of the timer corresponding to the target process, the terminal device may perform the first uplink data retransmission on the target configuration authorized resource associated with the target process according to the first indication information, and the target configuration authorized resource does not have a low utilization rate of the configuration authorized resource due to being in an idle state, so that the utilization rate of the configuration authorized resource is improved. In addition, since the terminal device retransmits the first uplink data on the target configuration authorized resource, the network device at the receiving end of the first uplink data can also receive the first uplink data for multiple times, so as to combine and decode the first uplink data received for multiple times, thereby improving the decoding success rate of the network device.

It should be noted that, when the terminal device retransmits the first uplink data on the target configuration authorized resource, the terminal device may stop the retransmission operation of the first uplink data when a preset condition is satisfied instead of executing the retransmission operation of the first uplink data without limitation. Optionally, the preset condition may include at least one of that a timer (that is, a timer corresponding to the target process) is overtime, that the number of data retransmissions reaches the maximum number of retransmissions, or that a dynamic scheduling indication message sent by the network device is received; the dynamic scheduling indication message is used for indicating the terminal device to perform second uplink data transmission for the resource dynamically scheduled by the network device through the PDCCH. Of course, the embodiment of the present application is described only by taking at least one of preset conditions that may include that a timer is overtime, the number of data retransmissions reaches the maximum number of retransmissions, or a received dynamic scheduling indication message sent by the network device as an example, and may be specifically set according to an actual need, where the embodiment of the present application is not limited further.

It can be seen that the preset condition may include any one of the timeout of the timer, the maximum retransmission times of the data retransmission times, or the reception of the dynamic scheduling indication message sent by the network device, or may also include any two of the timeout of the timer, the maximum retransmission times of the data retransmission times, or the reception of the dynamic scheduling indication message sent by the network device, or of course, may also include the timeout of the timer, the maximum retransmission times of the data retransmission times, or the reception of the dynamic scheduling indication message sent by the network device. It can be understood that, when the preset condition includes any two or three of the time-out of the timer, the maximum retransmission times of the data, or the reception of the dynamic scheduling indication message sent by the network device, whether the retransmission operation of the first uplink data needs to be stopped may be determined according to at least two ways. In one manner, whether the retransmission operation of the first uplink data needs to be stopped may be determined according to the time sequence in which the conditions are satisfied. The method specifically comprises the following steps: since any two conditions may not be satisfied at the same time, the retransmission operation of the first uplink data may be stopped when only one of the two or three conditions is satisfied first. For example, when the preset condition includes that the timer is overtime and the data retransmission number reaches the maximum retransmission number, the data retransmission number is 4, and the running time of the timer is 10ms, for example, when the data retransmission number reaches the maximum retransmission number of 4, the timer is not yet overtime, that is, the condition that the timer is overtime is not satisfied, at this time, since the condition that the data retransmission number reaches the maximum retransmission number is already satisfied, the retransmission operation of the first uplink data may be stopped. In another mode, whether the retransmission operation of the first uplink data needs to be stopped may be determined according to the priority of each condition. The method specifically comprises the following steps: the priority corresponding to each condition may be preset, and the retransmission operation of the first uplink data may be stopped only when the condition with the higher priority is satisfied. For example, when the preset condition includes that the number of data retransmissions reaches the maximum number of retransmissions and a dynamic scheduling indication message sent by the network device is received, taking the example that the priority corresponding to the number of data retransmissions reaching the maximum number of retransmissions is higher than the priority corresponding to the dynamic scheduling indication message sent by the network device, when the terminal device receives the dynamic scheduling indication message sent by the network device, the condition that the terminal device receives the dynamic scheduling indication message sent by the network device is satisfied, but since the priority corresponding to the number of data retransmissions reaching the maximum number of retransmissions is higher than the priority corresponding to the dynamic scheduling indication message sent by the network device, the retransmission operation of the first uplink data can be continuously performed, and only when the condition that the number of data retransmissions reaches the maximum number of retransmissions, that is, the condition that the number of data retransmissions reaches the maximum number of retransmissions is satisfied, the retransmission operation of the first uplink data is stopped. Of course, the embodiments of the present application are only described by taking these two modes as examples, and may be specifically set according to actual needs, and the embodiments of the present application are not further limited herein.

In the above description, when the preset condition includes that the number of data retransmissions reaches the maximum number of retransmissions, the terminal device needs to determine whether to stop the retransmission operation of the first uplink data according to whether the number of data retransmissions reaches the maximum number of retransmissions. In this case, the terminal device necessarily needs to acquire the maximum retransmission number first. Optionally, when the terminal device obtains the maximum retransmission time, the maximum retransmission time may be obtained through a resource configuration message sent by the network device, that is, the maximum retransmission time may be carried by the network device in the resource configuration message and sent to the terminal device. Of course, the maximum retransmission time may also be obtained through a single indication message sent by the network device, that is, the maximum retransmission time may also be carried in a single indication message by the network device and sent to the terminal device, and may be specifically set according to actual needs.

Among them, 1) a terminal device, also called a terminal and a user device, is a device providing voice and/or data connectivity to a user, for example, a handheld device with a wireless connection function, a vehicle-mounted device, and so on. Common terminal devices include, for example: cell-phone, panel computer, notebook computer, palm computer, Mobile Internet Device (MID), wearable equipment, wherein, wearable equipment includes for example: smart watches, smart bracelets, pedometers, and the like.

2) The network device may be an access device in a cellular network, such as a 5G base station, or a base station in a future new network system, etc., whose coverage area is illustrated as the solid circled area. Or may be an Access Point (AP) in a Wireless Local Area Network (WLAN), or the like.

In summary, it can be seen that, in the embodiment of the present application, because the configuration authorized resource message sent by the network device to the terminal device includes the first indication message, and when the first indication message indicates that the timer corresponding to the target process runs when the first uplink data is transmitted, the first uplink data retransmission is allowed to be performed on the target configuration authorized resource, the terminal device may perform the first uplink data retransmission on the target configuration authorized resource associated with the target process during the running of the timer corresponding to the target process, and the target configuration authorized resources will not be in an idle state to cause a low utilization rate of the configuration authorized resource, thereby improving the utilization rate of the configuration authorized resource. In addition, since the terminal device retransmits the first uplink data on the target configuration authorization resource, the network device can combine and decode the first uplink data received for multiple times, thereby improving the decoding success rate of the network device. Since the terminal device performs the first uplink data retransmission on the target configuration authorized resource associated with the target process during the running period of the timer corresponding to the target process, the terminal device necessarily needs to control the starting of the timer corresponding to the target process first, so that the terminal device can perform the first uplink data retransmission on the target configuration authorized resource associated with the target process during the running period of the timer corresponding to the target process.

As is known, when the system to which the uplink data retransmission method provided in the embodiment of the present application is applied is different, the timers corresponding to the target processes are also different. The method specifically comprises the following steps: when the retransmission method of the uplink data is applied to an NR system, the timer corresponding to the target process is a configuration authorization timer, namely a CG timer; when the retransmission method of the uplink data is applied to the NR-U system, the timer corresponding to the target process is a configured authorization retransmission timer, i.e., a CG retransmission timer. These two timers are identical in that: if the first indication information indicates that the first uplink data retransmission is allowed to be performed on the target configuration authorized resource when the timer corresponding to the target process runs during the transmission of the first uplink data, the terminal device may perform the first uplink data retransmission on the target configuration authorized resource associated with the target process during the running period of the CG timer or the CG retransmission timer. The two timers differ in that: if the first indication information indicates that the first uplink data retransmission is allowed to be performed on the target configuration authorized resource when the timer corresponding to the target process runs during the transmission of the first uplink data, when the timer corresponding to the target process is a CG timer, and after the CG timer is overtime, the terminal device may perform new uplink data transmission on the target configuration authorized resource; when the timer corresponding to the target process is the CG retransmission timer, the terminal device may retransmit the first uplink data on the target configuration authorized resource after the CG retransmission timer expires. If the first indication information indicates that retransmission of the first uplink data on the target configuration authorized resource is not allowed when the timer corresponding to the target process runs during transmission of the first uplink data, when the timer corresponding to the target process is a CG timer, the terminal device may transmit new uplink data on the target configuration authorized resource after the CG timer times out or stops; when the timer corresponding to the target process is the CG retransmission timer, the terminal device may retransmit the first uplink data on the target configuration authorization resource after the CG retransmission timer times out or stops.

No matter which timer of the two timers is the timer corresponding to the target process, the terminal device necessarily needs to control the start of the timer corresponding to the target process before the terminal device performs the first uplink data retransmission on the target configuration authorized resource associated with the target process. Optionally, when the timer corresponding to the control target process is started, the terminal device may control the timer to be started through at least two possible implementation manners. In a possible implementation manner, the terminal device may control the start of the timer corresponding to the target process when transmitting the first uplink data on the first configuration authorized resource (a resource in the configuration authorized resource configured for the terminal device by the network device) associated with the target process, that is, when the first uplink data is initially transmitted on the first configuration authorized resource associated with the target process, the start of the timer corresponding to the target process is controlled. In another possible implementation manner, when the terminal device transmits the first uplink data on the dynamic scheduling resource associated with the target process, the terminal device may control the timer corresponding to the target process to start, that is, when the first uplink data is initially transmitted on the dynamic scheduling resource associated with the target process (a resource in the configuration authorization resource that is not configured for the terminal device by the network device), the timer corresponding to the target process is controlled to start. Of course, the embodiments of the present application are only described by taking the timer start corresponding to the control target process in the two possible implementation manners as an example, but the embodiments of the present application are not limited thereto. In the following, a technical scheme of how to implement retransmission of uplink data by a terminal device during the running period of a timer corresponding to a target process after the timer corresponding to the target process is started will be described in detail with reference to the two different implementation manners.

It should be understood that the above description is only given for one uplink data transmission, and only one of the CG timer and the CG retransmission timer is started as an example, and of course, for one uplink data transmission, two timers may also be started simultaneously, that is, the CG timer and the CG retransmission timer are started simultaneously, but the lengths of the CG timer and the CG retransmission timer need to be configured separately. For example, when the lengths of the CG timer and the CG retransmission timer are configured separately, the lengths of the CG timer and the CG retransmission timer may be the same or different.

In a possible implementation manner, when the terminal device transmits the first uplink data on the first configuration authorized resource associated with the target process, the terminal device controls a timer corresponding to the target process to start. In combination with the possible control manner, after the timer corresponding to the target process is started, the terminal device may execute the technical scheme of the uplink data retransmission method provided in the embodiment of the present application. For example, please refer to fig. 3, where fig. 3 is a schematic flowchart of another uplink data retransmission method provided in the embodiment of the present application, where the method may include:

s301, the network equipment sends a resource configuration message to the terminal equipment.

The resource configuration message includes information of configuration authorized resources and first indication information, where the first indication information is used to indicate whether to allow retransmission of the first uplink data on a target configuration authorized resource associated with a target process in the configuration authorized resources when a timer corresponding to the target process runs during transmission of the first uplink data.

For example, when the network device sends the Resource configuration message to the terminal device, the Resource configuration message may be carried in a Radio Resource Control (RRC) signaling, or may be carried in a physical layer signaling, or of course, may be carried in a Media Access Control Address (MAC) signaling, or may be carried in other signaling.

It can be seen that, in the embodiment of the present application, a resource configuration message sent by a network device to a terminal device is different from the prior art in that the resource configuration message in the embodiment of the present application includes not only information for configuring an authorized resource, but also first indication information. It can be understood that, when the network device sends the first indication information to the terminal device, the first indication information may be included in the resource configuration message together with the information for configuring the authorized resource and sent to the terminal device, or may not be included in the resource configuration message together with the information for configuring the authorized resource and sent to the terminal device, that is, the first indication information may be carried in a certain indication message other than the resource configuration message and sent to the terminal device, so that the terminal device obtains the first indication information. Here, the embodiment of the present application is only described as an example that the first indication information and the information for configuring the authorized resource are included in the resource configuration message and are sent to the terminal device, and the first indication information and the information for configuring the authorized resource may be specifically set according to actual needs.

It goes without saying that, no matter how the network device sends the resource configuration message including the information of the configuration authorized resource and the first indication information to the terminal device, the network device needs to allocate the dedicated configuration authorized resource to the terminal device in advance before sending the resource configuration message, and then sends the information of the dedicated configuration authorized resource allocated to the terminal device, so that the terminal device determines the configuration authorized resource allocated to the terminal device according to the information of the configuration authorized resource. For example, the information of the configured authorized resource may be configured authorized period information and frequency domain resource location information, that is, the network device may send the configured authorized period information and the frequency domain resource location information to the terminal device; correspondingly, after receiving the configuration authorization period information and the frequency domain resource location information, the terminal device may determine, according to the configuration authorization period and the frequency domain resource location, a configuration authorization resource to determine an exclusive configuration authorization resource allocated to the terminal device by the network device, thereby obtaining the exclusive configuration authorization resource.

For the terminal device, after acquiring the configuration authorized resource and the first indication information allocated to the terminal device by the network device, the terminal device may determine, according to the first indication information, whether to allow the terminal device to perform the first uplink data retransmission on the target configuration authorized resource in the configuration authorized resources when the timer corresponding to the target process runs during the transmission of the first uplink data, that is, execute the following S302:

s302, the terminal device judges whether to allow the terminal device to perform first uplink data retransmission on a target configuration authorized resource associated with the target process in the configuration authorized resources according to the first indication information when a timer corresponding to the target process runs.

It should be noted that, in this possible implementation manner, since the first uplink data is initially transmitted on the first configuration authorized resource associated with the target process, during the operation of the timer corresponding to the target process when the terminal device transmits the first uplink data, if the terminal device needs to perform the retransmission of the first uplink data on the target configuration authorized resource in the configuration authorized resources, the network device needs to configure at least two configuration authorized resources associated with the target process for the terminal device in advance, that is, the network device needs to include at least two configuration authorized resources associated with the target process in the configuration authorized resources configured for the terminal device, that is, the number of the configuration authorized resources associated with the target process is at least two, where the at least two configuration authorized resources associated with the target process include one first configuration authorized resource and at least one second configuration authorized resource associated with the target process, correspondingly, the target configuration authorized resource for performing the first uplink data retransmission is any one of the at least one second configuration authorized resource. In other words, the first indication information is used to indicate whether to allow the terminal device to perform the first uplink data retransmission on the second configuration authorized resource when the timer corresponding to the target process operates during the transmission of the first uplink data, so that the terminal device may determine, according to the first indication information, whether to allow the terminal device to perform the first uplink data retransmission on the second configuration authorized resource when the timer corresponding to the target process operates.

It can be seen that, when the dedicated configuration authorization resource configured by the network device for the terminal device is described above, it is only limited that the dedicated configuration authorization resource includes at least two configuration authorization resources associated with the target process, and of course, the dedicated configuration authorization resource may also include a configuration authorization resource not associated with the target process, for example, a third configuration authorization resource associated with a process different from the target process. When the dedicated configuration authorization resource comprises a third configuration authorization resource associated with a process different from the target process, during the operation of a timer corresponding to the target process when the first uplink data is transmitted, if the terminal device needs to perform retransmission of the first uplink data on the target configuration authorization resource in the configuration authorization resources, it needs to search a second configuration authorization resource having the same target process in other configuration authorization resources except the first configuration authorization resource in the dedicated configuration authorization resource according to the information of the target process; and the first uplink data retransmission is carried out on the searched second configuration authorized resource, so that the terminal equipment can be prevented from carrying out the first uplink data retransmission on the third configuration authorized resource associated with the process different from the target process.

It can be understood that, if the terminal device needs to search a second configuration authorized resource having the same target process in other configuration authorized resources except the first configuration authorized resource in the dedicated configuration authorized resource according to the information of the target process, it needs to obtain information of a process associated with each configuration authorized resource in each dedicated configuration authorization. For example, the network device may reserve a process associated with each configured authorized resource for each terminal device in advance, and send information of the process associated with each configured authorized resource to the terminal device, so that the terminal device obtains the information of the process associated with each configured authorized resource. Optionally, when the network device sends the information of each process associated with the configuration authorized resource to the terminal device, the information of each process associated with the configuration authorized resource may be included in the resource configuration message together with the information of the configuration authorized resource and sent to the terminal device, or may not be included in the resource configuration message together with the information of the configuration authorized resource and sent to the terminal device, that is, the information of each process associated with the configuration authorized resource may be carried in a certain message other than the resource configuration message and sent to the terminal device, so that the terminal device obtains the information of each process associated with the configuration authorized resource, which may be specifically set according to actual needs.

For example, the information of the process associated with the configuration authorized resource may be represented by a process number, for example, the process number is 3, and the terminal device may count from 0 by default according to the process number 3, so as to obtain the process reserved for the configuration authorized resource by the network device, that is, the process 0, the process 1, and the process 2; certainly, the information of the process associated with the configuration authorized resource may be directly an identifier of the process, such as process 0, process 1, and process 2, so that the terminal device obtains the information of each process associated with the configuration authorized resource.

As can be known by referring to the relevant description in S302, in this embodiment, the first indication information may be used to indicate whether to allow the terminal device to perform the first uplink data retransmission on the second configuration authorized resource when the timer corresponding to the target process runs during the transmission of the first uplink data, so that the terminal device may determine, according to the first indication information, whether to allow the terminal device to perform the first uplink data retransmission on the second configuration authorized resource when the timer corresponding to the target process runs, and execute the following S303 or S304 according to the determination result:

s303, if the first indication information indicates that the first uplink data retransmission is allowed to be performed on the second configuration authorized resource, performing the first uplink data retransmission on the second configuration authorized resource associated with the target process until a preset condition is satisfied.

The preset condition is at least one of that a timer is overtime, the data retransmission times reach the maximum retransmission times, or a dynamic scheduling indication message sent by the network equipment is received; the dynamic scheduling indication message is used for indicating the terminal device to perform second uplink data transmission for the dynamically configured authorized resource of the terminal device through the network device.

Optionally, when the first uplink data is retransmitted on the second configuration authorized resource associated with the target process, the control module of the terminal device sends uplink authorization information and second indication information to the process module of the terminal device, where the second indication information is used to indicate that the network device does not receive the first uplink data; correspondingly, the process module may trigger the retransmission of the first uplink data on the second configuration grant resource associated with the target process according to the uplink grant information and the second indication information. It should be noted that, when the process module triggers the terminal device to perform the first uplink data retransmission on the second configuration authorized resource associated with the target process, the timer corresponding to the target process is not controlled to restart, that is, the timer corresponding to the target process continues to run along the current running time.

For example, the control module and the process module of the terminal device may be both software modules, that is, the functions of the control module and the process module are realized by software programs. The second indication information may be a Nack (negative acknowledgement) message, so as to indicate, through the Nack message, that the network device does not receive the first uplink data, and based on this, the process module of the terminal device may trigger retransmission of the first uplink data on the second configuration authorization resource associated with the target process.

Therefore, in the embodiment of the present application, if the first indication information indicates that retransmission of the first uplink data is allowed to be performed on the second configuration authorized resource, the terminal device retransmits the first uplink data on the second configuration authorized resource associated with the target process during the running of the timer corresponding to the target process, and the second configuration authorized resource does not have a low utilization rate of the configuration authorized resource due to being in an idle state, so that the utilization rate of the configuration authorized resource is improved. In addition, since the terminal device retransmits the first uplink data on the second configuration authorized resource, correspondingly, the network device also receives the first uplink data retransmitted by the terminal device, so that the network device can combine and decode the first uplink data received for multiple times, thereby improving the decoding success rate of the network device.

And S304, if the first indication information indicates that the first uplink data retransmission is not allowed to be performed on the second configuration authorized resource, performing the first uplink data retransmission on the second configuration authorized resource associated with the target process when the timer corresponding to the target process is overtime or is stopped, or transmitting the second uplink data on the second configuration authorized resource associated with the target process.

If the first indication information indicates that the retransmission of the first uplink data on the second configuration authorized resource is not allowed, it is determined that new transmission of the second uplink data is performed on the second configuration authorized resource or the retransmission of the first uplink data is performed on the second configuration authorized resource when the timer is overtime or stops according to the type of the timer corresponding to the target process.

If the timer corresponding to the target process is the CG timer, when the CG timer is overtime or stops, the terminal equipment transmits new second uplink data on a second configuration authorization resource; and if the timer corresponding to the target process is a CG retransmission timer, the terminal equipment retransmits the first uplink data on the second configuration authorization resource when the CG retransmission timer is overtime or stopped.

It should be noted that after S302 is executed, only either S303 or S304 needs to be executed according to the determination result in S302, that is, S303 and S304 cannot be executed simultaneously, and there is no sequence between S303 and S304.

To facilitate understanding of the uplink data retransmission method provided in the embodiment shown in fig. 3, the uplink data retransmission method provided in the embodiment of the present application will be described below by way of example. In this example, the timer corresponding to the target process is a CG timer, which can be shown in fig. 4 and fig. 5, where fig. 4 is a schematic diagram that allows uplink data retransmission to be performed on the second configuration authorized resource provided in the embodiment of the present application, and fig. 5 is a schematic diagram that does not allow uplink data retransmission to be performed on the second configuration authorized resource provided in the embodiment of the present application. As can be seen from fig. 4 and fig. 5, the network device configures 8 configuration authorized resources for the terminal device in advance, where 4 processes associated with the configuration authorized resources in the 8 configuration authorized resources are HARQ process 0, and 4 processes associated with the configuration authorized resources are HARQ process 1.

Before executing the uplink data retransmission method provided in the embodiment of the present application, the network device may include, in a resource configuration message, information and first indication information of 8 dedicated configuration authorization resources configured for the terminal device in advance, and send the resource configuration message to the terminal device, where for example, the resource configuration message may further include a maximum retransmission number 2 allowed for retransmission and a reserved HARQ process number 2. Correspondingly, after receiving the resource configuration message sent by the network device, the terminal device may determine the dedicated configuration authorized resource configured for the terminal device according to the respective information of the 8 dedicated configuration authorized resources, and determine HARQ processes reserved for the terminal device by the network device as HARQ process 0 and HARQ process 1 according to the reserved HARQ process number 2. Thus, when the data block 1 is transmitted on the first configuration authorized resource associated with the HARQ process 0, the terminal device may control the CG timer corresponding to the HARQ process 0 to start, and when the data block 2 is transmitted on the first configuration authorized resource associated with the HARQ process 0, the CG timer corresponding to the HARQ process 1 to start. When the CG timer corresponding to HARQ process 0 is started and the CG timer corresponding to HARQ process 1 is started, the terminal device may determine, according to the first indication information, whether to allow retransmission of data block 1 on any other second configuration grant associated with HARQ process 0 during the running period of the CG timer corresponding to HARQ process 0, and whether to allow retransmission of data block 1 on any other second configuration grant associated with HARQ process 1 during the running period of the CG timer corresponding to HARQ process 1, and perform corresponding operation according to the determination result.

If the first indication information indicates that the terminal device is allowed to perform uplink data retransmission on the second configuration authorized resource, and the maximum retransmission times allowed for retransmission are all 2, as shown in fig. 4, during the running period of the CG timer corresponding to HARQ process 0, the terminal device may perform retransmission of data block 1 on any other second configuration authorization associated with HARQ process 0, when the retransmission time of data block 1 reaches maximum retransmission time 2, even if the CG timer corresponding to HARQ process 0 has not timed out, at this time, the terminal device still needs to stop retransmitting data block 1 on the second configuration authorization, until the CG timer corresponding to HARQ process 0 times out, the terminal device will not perform data block 3 transmission on the second configuration authorization, and these second configuration authorized resources will not cause a low utilization rate of configuration authorized resources because they are in an idle state, thereby improving the utilization rate of the configuration authorization resources. And, because the terminal device retransmits the data block 1 on the second configuration authorized resource, correspondingly, the network device will also receive the retransmitted data block 1, so that the network device can combine and decode the data block 1 received for many times, thereby improving the decoding success rate of the network device. Similarly, during the running period of the CG timer corresponding to the HARQ process 1, the terminal device may perform retransmission of the data block 2 on any other second configuration grant associated with the HARQ process 1, when the retransmission time of the data block 2 reaches the maximum retransmission time of 2, even if the CG timer corresponding to the HARQ process 1 is not timed out, at this time, the terminal device still needs to stop retransmitting the data block 2 on the second configuration grant, until the CG timer corresponding to the HARQ process 1 is timed out, the terminal device will perform transmission of the data block 4 on the second configuration grant, and the second configuration grant resources will not cause a low utilization rate of the configuration grant resources due to being in an idle state, thereby improving the utilization rate of the configuration grant resources. In addition, since the terminal device retransmits the data block 2 on the second configuration authorized resource, correspondingly, the network device will also receive the retransmitted data block 2, so that the network device can combine and decode the data block 2 received for many times, thereby improving the decoding success rate of the network device.

On the contrary, if the first indication information indicates that uplink data retransmission is not allowed on the second configuration grant resource, as shown in fig. 5, during the running of the CG timer corresponding to HARQ process 0, the terminal device does not perform retransmission of data block 1 on any other second configuration grant associated with HARQ process 0, but after the CG timer corresponding to HARQ process 0 times out or stops, the terminal device will perform transmission of data block 3 on any other second configuration grant associated with HARQ process 0. Similarly, during the running period of the CG timer corresponding to HARQ process 1, the terminal device will not perform retransmission of data block 2 on any other second configuration grant associated with HARQ process 1, but will perform transmission of data block 4 on any other second configuration grant associated with HARQ process 1 until the CG timer corresponding to HARQ process 1 times out or stops.

Detailed description of the above embodiment shown in fig. 3 is that in a possible implementation manner, when the terminal device transmits the first uplink data on the first configuration authorized resource associated with the target process, the terminal device controls a timer corresponding to the target process to start. And in combination with the possible control manner, after the timer corresponding to the target process is started, how the terminal device executes the technical scheme of the uplink data retransmission method provided by the embodiment of the application. In another possible implementation manner, it will be described in detail below that when the terminal device transmits the first uplink data on the dynamic scheduling resource associated with the target process, the timer corresponding to the target process is controlled to start. And in combination with the possible control manner, after the timer corresponding to the target process is started, how the terminal device executes the technical scheme of the uplink data retransmission method provided by the embodiment of the application. For example, please refer to fig. 6, where fig. 6 is a schematic flowchart of another uplink data retransmission method provided in the embodiment of the present application, where the method may include:

s601, the network equipment sends a resource configuration message to the terminal equipment.

The resource configuration message comprises information of configuration authorization resources and first indication information, wherein the first indication information is used for indicating whether to allow the retransmission of the first uplink data on the target configuration authorization resources associated with the target process in the configuration authorization resources when a timer corresponding to the target process runs during the transmission of the first uplink data.

It can be understood that in S601, the related description thereof is similar to the related description in S301, and reference may be made to the related description in S301, and here, the embodiment of the present application is not repeated.

For the terminal device, after acquiring the configuration authorized resource and the first indication information allocated to the terminal device by the network device, the terminal device may determine, according to the first indication information, whether to allow the terminal device to perform retransmission of the first uplink data on the target configuration authorized resource in the configuration authorized resources when the timer corresponding to the target process runs during transmission of the first uplink data, that is, execute the following S602:

s602, according to the first indication information, whether the terminal device is allowed to perform first uplink data retransmission on a target configuration authorization resource associated with the target process in the configuration authorization resources is judged when a timer corresponding to the target process runs.

It should be noted that, in this possible implementation, unlike the embodiment shown in fig. 3, since the first uplink data is initially transmitted on the dynamic scheduling resource associated with the target process, if the terminal device wants to perform retransmission of the first uplink data on the target configuration grant resource in the configuration grant resources during the operation of the timer corresponding to the target process when transmitting the first uplink data, the network device needs to pre-configure the terminal device with at least one configuration authorization resource associated with the target process, namely, the configuration authorized resource configured by the network device for the terminal device, must include at least one configuration authorized resource associated with the target process, that is, the number of the configuration authorized resources associated with the target process is at least one, and correspondingly, the target configuration authorized resource for performing the first uplink data retransmission is any fourth configuration authorized resource in the at least one configuration authorized resource associated with the target process. In other words, the first indication information is used to indicate whether to allow the terminal device to perform the first uplink data retransmission on the fourth configuration authorized resource when the timer corresponding to the target process operates during the transmission of the first uplink data, so that the terminal device may determine, according to the first indication information, whether to allow the terminal device to perform the first uplink data retransmission on the fourth configuration authorized resource when the timer corresponding to the target process operates.

It can be seen that, when the dedicated configuration authorization resource configured by the network device for the terminal device is described above, it is only limited that the dedicated configuration authorization resource includes at least one configuration authorization resource associated with the target process, and of course, the dedicated configuration authorization resource may also include a configuration authorization resource not associated with the target process, for example, a third configuration authorization resource associated with a process different from the target process. When the exclusive configuration authorization resource comprises a third configuration authorization resource associated with a process different from the target process, during the operation of a timer corresponding to the target process when the first uplink data is transmitted, if the terminal device needs to perform retransmission of the first uplink data on the target configuration authorization resource in the configuration authorization resources, it needs to search a fourth configuration authorization resource having the same target process in the exclusive configuration authorization resource according to the information of the target process; and the first uplink data retransmission is carried out on the searched fourth configuration authorized resource, so that the terminal equipment can be prevented from carrying out the first uplink data retransmission on the third configuration authorized resource associated with the process different from the target process.

It can also be understood that, if the terminal device needs to search for a fourth configuration authorized resource having the same target process in the dedicated configuration authorized resource according to the information of the target process, it needs to obtain information of a process associated with each configuration authorized resource in each dedicated configuration authorization. For example, the network device may reserve a process associated with each configured authorized resource for each terminal device in advance, and send information of the process associated with each configured authorized resource to the terminal device, so that the terminal device obtains the information of the process associated with each configured authorized resource. Optionally, when the network device sends the information of each process associated with the configuration authorized resource to the terminal device, the information of each process associated with the configuration authorized resource may be included in the resource configuration message together with the information of the configuration authorized resource and sent to the terminal device, or may not be included in the resource configuration message together with the information of the configuration authorized resource and sent to the terminal device, that is, the information of each process associated with the configuration authorized resource may be carried in a certain message other than the resource configuration message and sent to the terminal device, so that the terminal device obtains the information of each process associated with the configuration authorized resource, which may be specifically set according to actual needs.

As can be seen from the description in S602, in this embodiment, the first indication information is used to indicate whether to allow the first uplink data retransmission to be performed on the fourth configuration authorized resource when the timer corresponding to the target process runs during the transmission of the first uplink data, so that the terminal device may determine, according to the first indication information, whether to allow the terminal device to perform the first uplink data retransmission to be performed on the fourth configuration authorized resource when the timer corresponding to the target process runs, and execute the following S603 or S604 according to the determination result:

s603, if the first indication information indicates that the first uplink data retransmission is allowed to be performed on the fourth configuration authorized resource, performing the first uplink data retransmission on the fourth configuration authorized resource until a preset condition is satisfied.

Optionally, when the first uplink data is retransmitted on the fourth configuration authorization resource associated with the target process, the control module of the terminal device sends uplink authorization information and second indication information to the process module of the terminal device, where the second indication information is used to indicate that the network device does not receive the first uplink data; correspondingly, the process module may trigger the retransmission of the first uplink data on the fourth configuration grant resource associated with the target process according to the uplink grant information and the second indication information. It should be noted that, when the process module triggers the terminal device to perform the first uplink data retransmission on the fourth configuration authorized resource associated with the target process, the timer corresponding to the target process is not controlled to restart, that is, the timer corresponding to the target process continues to run along the current running time.

Therefore, in the embodiment of the present application, if the first indication information indicates that the first uplink data retransmission is allowed to be performed in the fourth configuration authorized resource, the terminal device performs the first uplink data retransmission on the fourth configuration authorized resource associated with the target process during the running of the timer corresponding to the target process, and the fourth configuration authorized resource does not have a low utilization rate of the configuration authorized resource due to being in an idle state, so that the utilization rate of the configuration authorized resource is improved. In addition, since the terminal device retransmits the first uplink data on the fourth configuration authorized resource, correspondingly, the network device also receives the first uplink data retransmitted by the terminal device, so that the network device can combine and decode the first uplink data received for multiple times, thereby improving the decoding success rate of the network device.

S604, if the first indication information indicates that the first uplink data retransmission is not allowed to be performed on the fourth configuration authorized resource, performing the first uplink data retransmission on the fourth configuration authorized resource or transmitting the second uplink data on the fourth configuration authorized resource when the timer corresponding to the target process is overtime or is stopped.

If the first indication information indicates that the retransmission of the first uplink data on the fourth configuration authorized resource is not allowed, it is determined that, when the timer times out or stops, new transmission of the second uplink data on the fourth configuration authorized resource is performed or the retransmission of the first uplink data is performed on the fourth configuration authorized resource according to the type of the timer corresponding to the target process.

If the timer corresponding to the target process is the CG timer, when the CG timer is overtime or stopped, the terminal device transmits new second uplink data on a fourth configuration authorization resource; if the timer corresponding to the target process is the CG retransmission timer, the terminal device performs the first uplink data retransmission on the fourth configuration authorized resource when the CG retransmission timer is overtime or stopped.

It should be noted that after S602 is executed, only one of S603 and S604 needs to be executed according to the determination result in S602, that is, S603 and S604 cannot be executed simultaneously, and there is no sequence between S603 and S604.

Based on the retransmission method for the uplink data shown in the above embodiment, the protocol for receiving the uplink grant may be modified as follows:

for each serving cell and each uplink configuration grant, if configured and activated, the MAC entity performs:

1, if duration of Physical Uplink Shared Channel (PUSCH) of Uplink configuration authorization is not overlapped with PUSCH duration of Uplink resource received on Physical Downlink Control Channel (PDCCH) or PUSCH duration in random access response of the serving cell;

2> setting the HARQ process ID to the HARQ process ID associated with the PUSCH duration;

2> if HARQ process ID associated CG timer is not running;

3> the New Data Indicator (NDI) of the HARQ process is considered to have been flipped;

and 3, transmitting the uplink configuration authorization and the associated HARQ information to the HARQ entity.

4, the NDI bit of the HARQ process is not turned over;

and 4, transmitting the uplink configuration authorization and the associated HARQ information to the HARQ entity.

Based on the retransmission method for the uploaded data shown in the above embodiment, the protocol of the HARQ entity may be modified as follows:

2>else：

3> if the uplink resource received on the PDCCH is addressed to a Configured Scheduling cell radio network temporary identifier (CS-RNTI), and if the confirmed process HARQ buffer is empty; or

3> if uplink resources are part of the configured uplink resource bundle and no MAC PDU is acquired on the uplink resource bundle; or

3> if uplink resource is part of the configured uplink resource bundle and the PUSCH of the uplink resource overlaps with the PUSCH of another uplink resource received in the PDCCH or random access response of the serving cell;

4> ignore the uplink resource.

3>else：

and 5, when the transmission is executed, if the CG timer is configured by the corresponding HARQ process, starting or restarting the CG timer.
