[0056] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0057] It should be noted that the terms "comprise" and "have" and any variations thereof used in the present application are intended to cover non-exclusive inclusion. The term "a plurality of" used in the present application refers to two or more. The term "and / or" used in the present application refers to one of the options or any combination of a plurality of options.

[0058] The service and test item control signaling and data retransmission method provided by the embodiments of the present application can be applied to, for example, Figure 1The application environment shown. Among them, the industrial automation equipment 102 communicates with the control terminal 101 through the wireless network. The control terminal 101 configures the control / data retransmission signaling of the service and test item according to the retransmission requirement of the service and / or test item carrying device; wherein the control / data retransmission signaling of the service and test item is used to indicate the retransmission strategy of the service and / or test item carrying device; the retransmission strategy of the service and / or test item carrying device includes at least one of the uplink data retransmission strategy, the downlink control command / data retransmission strategy, the sending / receiving guarantee type strategy, and the service and / or test item carrying device connection maintenance type strategy; according to the control / data retransmission signaling of the service and test item, the retransmission carrier resource is allocated to the service and / or test item carrying device. Wherein, the industrial automation equipment 102 can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices, etc. The control terminal 101 can be gNB (5G base station).

[0059] In an exemplary embodiment, as shown in Figure 2 , a service and test item control signaling and data retransmission method is provided, which is applied to the control terminal in Figure 1 for example, including the following steps 201 to 202. Wherein:

[0060] Step 201, according to the retransmission requirement of the service and / or test item carrying device, configure the control / data retransmission signaling of the service and test item.

[0061] Because in the industrial automation application environment, different industrial application devices and sensors have unpredictable and random interference type and interference intensity, when the service and / or test item carrying device accesses the industrial automation equipment, the service and test item changes, the control terminal allocates the carrier resource, the change of the position of the service and test item carrying device, the difference of the retransmission mode of the downlink (Downlink, DL) based on the downlink control information (DCI, Downlink Control Information) of the radio resource control (RRC, Radio Resource Control), the uplink (Uplink, UL) link control protocol (LCP, Link Control Protocol) will limit the carrier resource reselection mechanism of the service and / or test item carrying device. This also makes the retransmission principle and mechanism on the industrial automation equipment more complex, especially the selection of retransmission opportunity, which will affect the normal sending / receiving of the control signaling and data of the existing service and / or test item carrying device.

[0062] To solve the above problems, the control terminal configures the control / data retransmission signaling of the service and the test item according to the retransmission requirements of the service and / or test item carrying device, wherein the control / data retransmission signaling of the service and the test item is used to indicate the retransmission strategy of the service and / or test item carrying device, so that the interaction between the control terminal and the service and / or test item carrying device can be realized based on the signaling, and the flexible configuration of the signaling can be completed. According to the control / data retransmission signaling of the service and the test item, the retransmission carrier resource is allocated to the service and / or test item carrying device. Therefore, different retransmission strategies can be flexibly configured according to the retransmission requirements of different service and / or test item carrying devices and the actual required total number of retransmission carrier resources, and the carrier resource utilization rate and transmission efficiency can be improved.

[0063] For example, as shown in FIG. 1, a composition structure of the control / data retransmission signaling of the service and the test item is shown, which is divided into several functional fields according to functions, and the functional fields include at least one of the service and test item control / data retransmission enabling field, the service and test item carrying device uplink retransmission confirmation field based on reselection measurement, the service and test item carrying device downlink control command retransmission confirmation field based on the control information configuration and distribution strategy, the service and test item control command and data retransmission interval configuration field, the service and test item control command and data retransmission block allocation field, the service and test item carrying device retransmission activation / deactivation feedback confirmation field, the service and test item control command and data retransmission strategy selection field, and the service and test item retransmission feedback field. Figure 3 It should be noted that the embodiment gives a possible configuration example of the control / data retransmission signaling of the service and the test item, and in actual application, different fields (for example, different field names and different numbers) can be divided according to needs, and the functions of each field can be defined. In the program running, the definition of the field name does not affect the actual function.

[0064] The service and test item control / data retransmission enabling field is used to enable / disable each functional field in the service and test item control / data retransmission signaling.

[0065] The service and test item carrying device uplink retransmission confirmation field based on reselection measurement is used to indicate the service and / or test item carrying device to measure the information on the carrier resource allocated by the control terminal, determine the data content that needs to be retransmitted, the required carrier size, and the carrier position and carrier size that can carry the retransmission data.

[0066]

[0067] ​Optionally, the service and / or test item carrying device is limited by the uplink link control protocol, and thus the service and / or test item carrying device needs to measure information on the carrier resource allocated by the control end. The information on the carrier resource allocated by the control end includes but is not limited to the service and / or test item carrying device position, minimum throughput requirement, interference type and / or interference strength, path loss, etc. In addition, the service and / or test item carrying device also needs to confirm information such as data content that needs to be retransmitted by itself, required carrier size, and carrier position and carrier size that can carry the retransmitted data.

[0068] It should be noted that the actual retransmission carrier position and carrier size of the uplink of the service and / or test item carrying device, the data content, and the required carrier size, etc. are determined according to the service and / or test item control command and data retransmission strategy selection field based on the measurement result of the control end.

[0069] The control command retransmission confirmation field of the service and / or test item carrying device downlink based on the control information configuration issued strategy is used to determine the transmission mode of the uplink retransmission radio resource control information, the retransmission mode after the service and / or test item is activated / deactivated on the uplink and / or downlink, and the feedback mode of the retransmission flow of the retransmission carrier resource allocated on the service and / or test item carrying device.

[0070] Optionally, the transmission mode of the uplink retransmission radio resource control information includes but is not limited to reuse, coverage, multiplexing, etc.

[0071] Optionally, the retransmission mode after the service and / or test item is activated / deactivated on the uplink and / or downlink includes but is not limited to retransmission before the next transmission, retransmission at the end of the current transmission, retransmission at a position pre-configured by the control end, etc.

[0072] Optionally, the feedback mode of the retransmission flow of the retransmission carrier resource allocated on the service and / or test item carrying device includes but is not limited to feedback on the specified carrier and / or all carrier resources after the first connection retransmission of the service and / or test item carrying device, separate and / or combined feedback when retransmitting the same service and / or test item, separate and / or combined feedback before the next control command and / or data transmission, separate and / or combined feedback at the end of the current transmission, separate and / or combined feedback at a position pre-configured by the control end, etc.

[0073] It should be noted that the transmission mode and feedback mode on the control command of the service and / or test item carrying device downlink based on the control information configuration issued strategy are determined according to the service and / or test item control command and data retransmission strategy selection field.

[0074] The service and test item control command and data retransmission interval configuration field is used to determine the time interval of the control command and data retransmission of the service and test item bearing device, the retransmission feedback interval after the service and / or test item activation / deactivation, and the sending confirmation interval of the retransmission feedback radio resource control information.

[0075] It should be noted that the service and test item control command and data retransmission interval configuration is determined according to the service and test item control command and data retransmission strategy selection field.

[0076] The service and test item control command and data retransmission block allocation field is used to determine the carrier resource block allocation confirmation field of the service and / or test item activation / deactivation control command of the service and / or test item bearing device, various types of retransmission-related control commands, and data sending / receiving.

[0077] Optionally, the various types of retransmission-related control commands include but are not limited to: the normal control command on the control end, the service and / or test item bearing device, the data sending / receiving command, and the control command during retransmission.

[0078] Optionally, the data retransmission block allocation strategy indicated by the carrier resource block allocation confirmation field of data sending / receiving includes but is not limited to: a single service and / or test item supporting a single and / or multiple retransmission carrier resource blocks, multiple same types of services and / or test items supporting a single and / or multiple retransmission carrier resource blocks, multiple different types of services and / or test items supporting a single and / or multiple retransmission carrier resource blocks, etc.

[0079] It should be noted that the service and test item control command and data retransmission block allocation is determined according to the service and test item control command and data retransmission strategy selection field.

[0080] The service and test item bearing device retransmission activation / deactivation feedback confirmation field is used to confirm the enable / disable information of all retransmission feedbacks on the carrier resource, the uplink, and / or the downlink.

[0081] It should be noted that the service and test item bearing device retransmission activation / deactivation feedback confirmation is determined according to the service and test item control command and data retransmission strategy selection field.

[0082] The service and test item control command and data retransmission strategy selection field is used to configure different numbers of service and / or test item bearing devices and determine the retransmission strategy of the service and / or test item bearing device.

[0083] Optionally, the retransmission strategy of the service and / or test item carrying device includes: determining the simultaneous retransmission of the service and / or test item type, control command and / or data, independent and / or parallel of uplink and / or downlink, different retransmission carrier resource quantity, retransmission feedback of retransmission activation / deactivation, enable / disable information, etc.

[0084] The service and test item retransmission feedback field is used to complete the signaling interaction and state confirmation with the service and / or test item carrying device.

[0085] As shown in the example, Figure 4 , a network architecture diagram of service and test item control signaling and data retransmission is provided, which can be applied to the network architecture of terminal (UE) and base station (gNB). In the network architecture, the above-mentioned Figure 2 The retransmission method of service and test item control signaling and data is shown. Among them, interference type 1: gNB to gNB sub-band inter-link interference (CLI) refers to the interference from another gNB transmitter to the gNB receiver. Interference type 2: inter-sub-band cross-link interference (CLI) between UEs in the same area refers to the influence of UE transmission on another UE on non-overlapping resources in the same area. Interference type 3: inter-sub-band cross-link interference (CLI) between UEs in adjacent areas refers to the influence of UE transmission on another UE on non-overlapping resources in adjacent areas. Interference type 4: interference of UEs in one area to gNBs in other areas refers to the transmission of UEs in one area to the uplink (UL) reception of gNBs in other areas. Interference type 5: interference of gNBs in one area to UEs in other areas refers to the downlink (DL) reception of UEs in other areas by gNBs in one area. Interference type 6: new inter-area strong interference caused by area identifier conflict refers to the strong inter-area interference of UEs at the edge of the area caused by gNBs with the same identifier in adjacent areas due to area identifier conflict; due to area identifier conflict, multiple gNBs use different interference suppression methods when the same UE is in different areas at different positions, resulting in the UE simultaneously receiving different types of strong interference.

[0086] It should be understood that when the control end allocates control channel resources (including but not limited to: carrier resources, time domain / frequency domain / code domain resources, etc.), it can be allocated in the following two ways, but is not limited thereto.

[0087] The first mode (uplink data retransmission strategy): in the case of uplink data retransmission, the control / data retransmission signaling of the service and test item is configured to carry the uplink retransmission confirmation field of the service and test item based on the reselection measurement; the total number of carrier resources required for uplink data retransmission of the same type of service and / or test item is counted, and the total size of the carrier resources required for retransmission of all services and / or test items is determined; the reference retransmission carrier resource size (such as the minimum and / or basic retransmission carrier resource size) is set in advance, and the actual target retransmission carrier resource size required (such as the actual minimum and / or basic retransmission carrier resource size) is determined according to the total size of the carrier resources required for retransmission; at least one actual target retransmission carrier resource size is allocated to at least one service and / or test item carrying device in a predetermined carrier resource position requiring retransmission, and / or to a pre-allocated retransmission carrier resource; the service and test item control command and data retransmission block allocation field, the service and test item control command and data retransmission interval configuration field, the service and test item carrying device retransmission activation / deactivation feedback confirmation field, and the service and test item control command and data retransmission strategy selection field in the control / data retransmission signaling of the service and test item are configured respectively.

[0088] For the first mode, the application scenarios can be: at least one service and / or test item carrying device access / disconnection control terminal, service and / or test item change of at least one service and / or test item carrying device, and working environment change of at least one service and / or test item carrying device, such as: minimum throughput requirement, interference type and / or interference intensity, and road loss change, but not limited to this.

[0089] Optionally, before configuring the control / data retransmission signaling of the service and test item, the service and / or test item carrying device position, the minimum throughput requirement, the interference type and / or the interference intensity, and the road loss need to be determined; and the data content, the required carrier size, and the carrier position and carrier size capable of carrying the retransmission data confirmed by the service and / or test item carrying device need to be confirmed.

[0090] Optionally, the selection method of the data requiring retransmission on the allocated retransmission block includes but is not limited to: retransmitting all data on all data retransmission blocks, and using time domain / frequency domain / code domain multiplexing between data retransmission blocks to enhance the robustness of retransmission; the control terminal divides the data requiring retransmission into different blocks, and sends different blocks on different data retransmission blocks; all data retransmission blocks use interleaving to send / receive, so as to minimize the number of retransmissions.

[0091] Alternatively, at least one of the following methods can be selected: completing control command and data retransmission each time data is sent / received; completing control command and data retransmission after feedback from the service and / or test item carrying equipment; completing control command and data retransmission after exceeding the feedback time threshold preset by the control end; or using different retransmission time intervals on the carrier resource blocks of different retransmission data carriers.

[0092] The second approach (downlink control command / data retransmission strategy): When downlink control command / data retransmission is required, configure the control command retransmission confirmation field in the downlink configuration strategy of the service and test item bearer equipment in the control / data retransmission signaling for services and test items; count the total number of carrier resources required for uplink data retransmission by the same type of service and / or test item bearer equipment, and determine the total size of carrier resources required for retransmission by all service and / or test item bearer equipment that need to retransmit; pre-set the reference retransmission carrier resource size (e.g., minimum and / or basic retransmission carrier resource size), and determine the total size of carrier resources required for retransmission as needed. The actual total number of target retransmission carrier resources required (e.g., the actual minimum and / or basic total number of retransmission carrier resources required); allocate at least one actual total number of target retransmission carrier resources to at least one carrier resource location that needs to be retransmitted as predetermined by the service and / or test item bearer equipment, and / or allocate them to pre-allocated retransmission carrier resources; configure the service and test item control command and data retransmission block allocation field, service and test item control command and data retransmission interval configuration field, service and test item bearer equipment retransmission activation / deactivation feedback confirmation field, and service and test item control command and data retransmission strategy selection field in the control / data retransmission signaling of the service and test item respectively.

[0093] For the second approach, the application scenarios can be: at least one service and / or test item carrier device accessing / disconnecting from the control terminal, at least one service and / or test item carrier device undergoing service and / or test item changes, at least one service and / or test item carrier device undergoing operating environment changes, such as changes in minimum throughput requirements, interference type and / or interference intensity, path loss, etc., but not limited to these.

[0094] Optionally, before configuring the control / data retransmission signaling for services and test items, it is also necessary to determine the location of the service and / or test item carrying equipment, minimum throughput requirements, interference type and / or interference intensity, path loss, etc.; and the service and / or test item carrying equipment to confirm the data content to be retransmitted, the required carrier size, and the carrier location and carrier size that can carry the retransmitted data.

[0095] Optionally, the selection of data requiring retransmission on the allocated retransmission blocks includes, but is not limited to, retransmitting all data on all data retransmission blocks, multiplexing in time domain / frequency domain / code domain between data retransmission blocks to enhance the robustness of retransmission, the control end dividing the data requiring retransmission into different blocks, and sending different blocks on different data retransmission blocks, and all data retransmission blocks using interleaving to send / receive, so as to minimize the number of retransmissions.

[0096] Optionally, at least one of the following options can be selected: completing the control command and data retransmission after each data sending / receiving, completing the control command and data retransmission after completing the control command and data retransmission of the service and / or test item carrying device feedback, completing the control command and data retransmission after exceeding the feedback time threshold set by the control end in advance, and using different retransmission time intervals on different retransmission data carrying carrier resource blocks.

[0097] The actual minimum and / or basic retransmission carrier resource total number required is calculated according to the following formula:

[0098]

[0099] In the formula: Totals Min basic carriers of Retransmission represents the actual minimum and / or basic retransmission carrier resource total number required; Totals Size of Retransm tssion carriers represents the total size of the carrier resources requiring retransmission; Sizes Min basic carriers of Retransmission represents the minimum and / or basic retransmission carrier resource size set by the control end in advance; ceil represents the ceiling function.

[0100] Step 202: According to the control / data retransmission signaling of the service and test item, the retransmission carrier resources are allocated to the service and / or test item carrying device.

[0101] For example, as shown in FIG. 2, the resource allocation modes of different carrying devices are shown. The devices are divided into two categories: carrying devices requiring retransmission and carrying devices not requiring retransmission. The carrier resources are divided into three categories: retransmission and / or feedback carrier resources, normal carrier resources, and reserved retransmission carrier resources. Figure 5

[0102] Optionally, for the service and / or test item carrying device requiring retransmission, the retransmission and / or feedback carrier resources are re-divided on the carrier resources already allocated by the service and / or test item carrying device itself, for data sending / receiving during retransmission.

[0103] Optionally, for the service and / or test item carrying device requiring retransmission, the retransmission and / or feedback carrier resources are not re-divided on the carrier resources already allocated by the service and / or test item carrying device itself, but the retransmission carrier resources are re-allocated on the reserved retransmission carrier resources, for data sending / receiving during retransmission.​

[0104] Optionally, for the service and / or test item carrying device which does not need retransmission, a carrier resource allocation strategy is determined for the service and / or test item carrying device which does not need retransmission according to the control / data retransmission signaling of the service and the test item; wherein the carrier resource allocation strategy includes: no retransmission and / or feedback carrier resource is reserved, and all carrier resources of the service and / or test item carrying device are used for data transmission / reception of itself; or, retransmission and / or feedback carrier resource is reserved, and the reserved retransmission and / or feedback carrier resource is used for direct data transmission / reception when retransmission is performed.

[0105] Taking a conventional transmission / reception guarantee type (transmission / reception guarantee type strategy) as an example, its application scenario is: the service and / or test item data transmission of the service and / or test item carrying device needs a larger carrier resource to complete, there is no excessive retransmission demand and / or retransmission carrier resource allocation, the control command of the control end needs stable transmission / reception, the service and / or test item has no frequent change, and at least one of the following conditions is determined based on the position measurement of the service and / or test item carrying device, the minimum throughput demand, the interference type and / or interference strength, the path loss, and the like: the working environment is stable.

[0106] Illustratively, the control end allocates and confirms a larger carrier position and carrier size capable of carrying retransmission data, so as to facilitate the transmission / reception of larger size service and / or test item data and control command.

[0107] Illustratively, the control end pre-sets a larger size of minimum and / or basic retransmission carrier resource size, and completes the transmission of retransmission data by a single large size and a total number of minimum and / or basic retransmission carrier resources which are actually needed and are less in total, so as to reduce the number of signaling interactions as much as possible and increase the effective payload.

[0108] Illustratively, the control end transmits the retransmission control command and data only after the current conventional control command and / or data transmission / reception, or at the position pre-configured by the control end.

[0109] Illustratively, the control end transmits the control command by covering the original control command, which can reduce the number of times of conventional transmission and retransmission of the control command and increase the effective payload.

[0110] Illustratively, the control end transmits the data as a whole by covering the joint of the part of the data to be retransmitted and the part of the conventional data which does not need retransmission, so as to further reduce the number of carrier resources occupied by retransmission and increase the effective payload.

[0111] For example, the control end uses a small number of retransmission carrier resource blocks, divides the data to be retransmitted into different blocks, transmits the different blocks on different data retransmission blocks, and transmits / receives all the data retransmission blocks in an interleaved manner, so as to reduce the number of retransmissions as much as possible.

[0112] For example, the control end completes control command and data retransmission after the control end service and / or test item bearing device feedback, so as to reduce the number of retransmissions as much as possible.

[0113] For example, the control end activates and / or deactivates the original service and / or test item after the first retransmission after the service and / or test item is changed, without the need for feedback.

[0114] For example, the service and / or test item bearing device connection maintaining type (service and / or test item bearing device connection maintaining type strategy) is used in the following application scenarios: the service and / or test item data transmission of the service and / or test item bearing device needs to be completed by using medium and / or small carrier resources, a large number of retransmission requirements and / or retransmission carrier resource allocation are needed, the transmission / reception of the control command of the control end is unstable, the service and / or test item is frequently changed, and at least one of the following conditions is determined based on the location measurement, minimum throughput requirement, interference type and / or interference strength, and path loss of the service and / or test item bearing device: the working environment is unstable.

[0115] For example, the control end allocates and confirms medium or small carrier positions and carrier sizes that can carry retransmission data, so as to facilitate the transmission / reception of fragmented size service and / or test item data and control commands.

[0116] For example, the control end pre-sets a small size minimum and / or basic retransmission carrier resource size, and transmits the retransmission data by using a large number of small sizes, that is, a large number of actual minimum and / or basic retransmission carrier resources, so as to guarantee the retransmission quality as much as possible and maintain the connection on the service and / or test item bearing device.

[0117] For example, the control end transmits the retransmission control command and data before the next transmission or at a position pre-configured by the control end, so that the control end and the service and / or test item bearing device receive the normal data again after retransmission error correction, so as to reduce the number of retransmissions as much as possible.

[0118] For example, the control end transmits the control command by using the original control command and the retransmission command at the same time, so as to ensure the accuracy of the control command decoding and reduce the number of retransmissions as much as possible.

[0119] Exemplarily, the control end completes the overall sending of data by means of jointing the data part to be retransmitted and all the regular data parts, and when the service and / or test item carrying device receives the data, the retransmission data part and the corresponding part of the regular data complete decoding by means of multiplexing, so as to enhance the robustness of retransmission and reduce the retransmission times as much as possible.

[0120] Exemplarily, the control end adopts a large number of retransmission carrier resource blocks, retransmits all the data on all the data retransmission blocks, and adopts multiplexing in the time domain / frequency domain / code domain between the data retransmission blocks, so as to enhance the robustness of retransmission and reduce the retransmission times as much as possible.

[0121] Exemplarily, the control end service and / or test item carrying device has no feedback, or retransmits within a predetermined retransmission feedback time threshold of the control end, so as to guarantee the connectivity on the service and / or test item carrying device as much as possible.

[0122] Exemplarily, after the control end receives the retransmission completion feedback after the service and / or test item is changed, the original service and / or test item is activated and / or deactivated, and feedback is required.

[0123] It should be understood that the service and / or test item carrying device requiring retransmission can redivide the retransmission and / or feedback carrier resources on the carrier resources already allocated by itself, for data sending / receiving during retransmission. Figure 5 As shown in the carrying device 1 of the carrying device 1, it is mainly applied to the scene that there are more carrier resources on the carrying device, and can meet the carrier resource allocation during retransmission.

[0124] It should be understood that the service and / or test item carrying device requiring retransmission can not redivide the retransmission and / or feedback carrier resources on the carrier resources already allocated by itself. The control end allocates new retransmission carrier resources on the reserved retransmission carrier resources. Figure 5 As shown in the carrying device 3 of the carrying device 3, it is mainly applied to the scene that there are no spare carrier resources on the carrying device for carrier resource allocation during retransmission.

[0125] It should be understood that the service and / or test item carrying device not requiring retransmission can not reserve retransmission and / or feedback carrier resources, i.e., all the carrier resources of itself are used for data sending / receiving of itself. Figure 5 As shown in the carrying device 2 of the carrying device 2, it can improve the effective load of the carrier resources of itself.

[0126] It should be understood that the service and / or test item carrying device not requiring retransmission can reserve retransmission and / or feedback carrier resources. Figure 5The shown carrying device 4, its implementation method is same with carrying device 1. The control end does not need to re-allocate retransmission carrier resource on the reserved retransmission carrier resource, and directly uses the reserved retransmission and / or feedback carrier resource when retransmission is needed.

[0127] In the retransmission method of the control signaling and data of the service and test item, the control / data retransmission signaling of the service and test item is configured according to the retransmission requirement of the service and / or test item carrying device; wherein the control / data retransmission signaling of the service and test item is used to indicate the retransmission strategy of the service and / or test item carrying device; so that the interaction between the control end and the service and / or test item carrying device can be realized based on the signaling, and the flexible configuration of the signaling can be completed. The retransmission carrier resource is allocated for the service and / or test item carrying device according to the control / data retransmission signaling of the service and test item. Therefore, different retransmission strategies can be flexibly configured according to the retransmission requirement of different service and / or test item carrying devices and the actual required total number of retransmission carrier resources, and the carrier resource utilization rate and transmission efficiency can be improved.

[0128] In another exemplary embodiment, as shown in Figure 6 , a retransmission method of control signaling and data of service and test item is provided, which is applied to the control end in Figure 1 for example, and includes the following steps 601 to 603.

[0129] Among them:

[0130] Step 601, receiving the measurement data reported by the service and / or test item carrying device.

[0131] Among them, the measurement data is used to determine the retransmission requirement between the control end and the service and / or test item carrying device.

[0132] Optionally, the measurement data includes at least one of the following: the position of the service and / or test item carrying device, the minimum throughput requirement, the interference type and / or interference intensity, the path loss, and the data content that the service and / or test item carrying device itself needs to retransmit, the required carrier size, the carrier position and carrier size that can carry the retransmission data.

[0133] Step 602, configuring the control / data retransmission signaling of the service and test item according to the retransmission requirement of the service and / or test item carrying device.

[0134] Step 603, allocating retransmission carrier resource for the service and / or test item carrying device according to the control / data retransmission signaling of the service and test item.

[0135] In this embodiment, the specific implementation process and technical effects of steps 602-603 are described in Figure 2The related description of steps 201-202 in the method embodiment is not repeated here.

[0136] Optionally, before step 602 is performed, the control end can also initialize each function field in the control / data retransmission signaling of the service and test item.

[0137] For example, Figure 7 As shown, an interactive flowchart of a service and test item control signaling and data retransmission method is provided. The method can include the following steps:

[0138] Step 701: The control end initializes each function field in the control / data retransmission signaling of the service and test item.

[0139] Step 702: The control end receives the measurement data reported by the service and / or test item bearing device.

[0140] Step 703: The control end configures each function field in the control / data retransmission signaling of the service and test item according to the measurement data.

[0141] Step 704: The control end sends the control / data retransmission signaling of the service and test item to the service and / or test item bearing device.

[0142] Step 705: The control end, the service and / or test item bearing device executes the retransmission strategy indicated by the control / data retransmission signaling of the service and test item.

[0143] It should be understood that although each step in the flowchart involved in the above embodiments is shown in sequence according to the arrow, these steps are not necessarily executed in the order indicated by the arrow. Unless otherwise stated herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other orders. Moreover, at least part of the steps in the flowchart involved in the above embodiments can include multiple steps or stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily sequential, but can be alternately executed with other steps or steps or stages in other steps. It can be understood that the steps in different embodiments can be freely combined as needed, and various non-contradictory schemes formed by combination are within the scope of protection of the present application.

[0144] Based on the same inventive concept, the embodiments of the present application further provide a device for retransmitting the service and test item control signaling and data. The device provides a solution similar to the solution provided in the above method, and thus the specific limitations in one or more device embodiments for retransmitting the service and test item control signaling and data provided below can refer to the limitations of the retransmitting method of the service and test item control signaling and data provided above, and will not be described here again.

[0145] In an exemplary embodiment, as shown in Figure 8 a device for retransmitting the service and test item control signaling and data is provided, comprising: a configuration module 801 and an allocation module 802, wherein:

[0146] The configuration module 801 is configured to configure the service and test item control / data retransmission signaling according to the retransmission requirement of the service and / or test item carrying device; wherein the service and test item control / data retransmission signaling is used to indicate the retransmission strategy of the service and / or test item carrying device; the retransmission strategy of the service and / or test item carrying device includes at least one of the uplink data retransmission strategy, the downlink control command / data retransmission strategy, the sending / receiving guarantee type strategy, and the service and / or test item carrying device connection maintenance type strategy.

[0147] The allocation module 802 is configured to allocate retransmission carrier resources for the service and / or test item carrying device according to the service and test item control / data retransmission signaling.

[0148] Exemplarily, the service and test item control / data retransmission signaling is divided into several functional fields according to functions, and the functional fields include at least one of the service and test item control / data retransmission enabling field, the service and test item carrying device uplink retransmission confirmation field based on reselection measurement, the service and test item carrying device downlink control command retransmission confirmation field based on the control information configuration issuing strategy, the service and test item control command and data retransmission interval configuration field, the service and test item control command and data retransmission block allocation field, the service and test item carrying device retransmission activation / deactivation feedback confirmation field, the service and test item control command and data retransmission strategy selection field, and the service and test item retransmission feedback field.

[0149] Exemplarily, the service and test item control / data retransmission enabling field is used to enable / disable each functional field in the service and test item control / data retransmission signaling.

[0150] The retransmission confirmation field of the service and test item carrying device uplink based on reselection measurement is used to indicate the information on the carrier resource allocated by the service and / or test item carrying device measurement control end, determine the data content which needs to be retransmitted by itself, the required carrier size, the carrier position and carrier size which can carry the retransmitted data;

[0151] The control command retransmission confirmation field of the service and test item carrying device downlink based on the control information configuration issued strategy is used to transmit the retransmission wireless resource control information of the uplink through the downlink control information configuration, the retransmission mode after the service and / or test item activation / deactivation on the uplink and / or downlink, and the feedback mode of the retransmission flow of the retransmission carrier resource allocated by the service and / or test item carrying device;

[0152] The service and test item control command and data retransmission interval configuration field is used to determine the time interval of the control command and data retransmission of the service and test item carrying device, the retransmission feedback interval after the service and / or test item activation / deactivation, and the transmission confirmation interval of the retransmission feedback wireless resource control information;

[0153] The service and test item control command and data retransmission block allocation field is used to determine the service and / or test item activation / deactivation control command of the service and / or test item carrying device, the carrier resource block allocation confirmation field of various retransmission related control commands and data transmission / reception; the carrier resource block allocation confirmation field of data transmission / reception is used to indicate the allocation strategy of the data retransmission block;

[0154] The service and test item carrying device retransmission activation / deactivation feedback confirmation field is used to confirm the enable / disable information of all the retransmission feedback on the carrier resource, uplink and / or downlink;

[0155] The service and test item control command and data retransmission strategy selection field is used to configure different number of service and / or test item carrying devices, and determine the retransmission strategy of the service and / or test item carrying device;

[0156] The service and test item retransmission feedback field is used to complete the signaling interaction and state confirmation between the service and / or test item carrying device.

[0157] For example, the configuration module 801 is specifically configured to: in the case that the data retransmission is required on the uplink, configure the retransmission confirmation field of the service and test item carrying device uplink based on the reselection measurement in the control / data retransmission signaling of the service and test item; or in the case that the control command / data retransmission is required on the downlink, configure the control command retransmission confirmation field of the service and test item carrying device downlink based on the control information configuration issued strategy in the control / data retransmission signaling of the service and test item;

[0158] counting a total number of carrier resources required by the same type of service and / or test item bearer device for uplink data retransmission, determining a total size of carrier resources required by all service and / or test item bearer devices for retransmission, presetting a reference retransmission carrier resource size, determining a total number of target retransmission carrier resources actually required according to the total size of carrier resources required for retransmission, allocating the at least one total number of target retransmission carrier resources actually required to at least one service and / or test item bearer device at a position of carrier resources required for retransmission determined in advance, and / or to a retransmission carrier resource allocated in advance, and respectively configuring a service and test item control command and data retransmission block allocation field, a service and test item control command and data retransmission interval configuration field, a service and test item bearer device retransmission activation / deactivation feedback acknowledgement field, and a service and test item control command and data retransmission strategy selection field in service and test item control / data retransmission signaling.

[0159] For example, the apparatus can further include a receiving module 803 configured to receive measurement data reported by the service and / or test item bearer device, the measurement data being used to determine retransmission requirements between the control end and the service and / or test item bearer device.

[0160] The measurement data can include at least one of a position, a minimum throughput requirement, an interference type and / or an interference strength, a path loss of the service and / or test item bearer device, and data content required for retransmission by the service and / or test item bearer device, a required carrier size, and a carrier position and carrier size capable of carrying retransmission data.

[0161] For example, the allocating module 802 can be specifically configured to, for the service and / or test item bearer device required for retransmission, redivide retransmission and / or feedback carrier resources on carrier resources already allocated by the service and / or test item bearer device itself, for data transmission / reception during retransmission; and / or

[0162] For the service and / or test item bearer device required for retransmission, redivide retransmission and / or feedback carrier resources on carrier resources already allocated by the service and / or test item bearer device itself, and re-allocate retransmission carrier resources on reserved retransmission carrier resources, for data transmission / reception during retransmission.

[0163] For example, the allocation module 802 is specifically used to: determine a carrier resource allocation strategy for the service and / or test item bearer equipment that does not require retransmission, based on the control / data retransmission signaling of the service and test item; wherein the carrier resource allocation strategy includes: not reserving retransmission and / or feedback carrier resources, and using all carrier resources of the service and / or test item bearer equipment for its own data transmission / reception; or, reserving retransmission and / or feedback carrier resources, and using the reserved retransmission and / or feedback carrier resources for direct data transmission / reception during retransmission.
