Description

Technical Field

[0001] The present invention relates to wireless communication technology, and in particular to a transmission resource scheduling method, device and system. Background Art

[0002] With the development of communication technology, the research on the fifth generation of mobile communication technology (5G) has also been launched. The wireless access of 5G is called New Radio, or NR for short. At present, the three major application scenarios defined by 5G, namely enhanced mobile broadband (eMBB), massive machine type communications (mMTC) and ultra-reliable and low latency communications (URLLC), all use spectrum resources below 6 GHz. In the long-term evolution (LTE) system, the frequency resources used by the terminal to communicate through LTE are all around 2 GHz. Therefore, when the terminal communicates through LTE and NR at the same time, there is a high possibility of interference between the two frequency bands. These interferences may include: cross-modulation interference, harmonic interference and harmonic mixing interference. These interferences will cause the terminal to be unable to send and receive data through LTE and NR at the same time. In other words, the terminal sending data through LTE will interfere with the terminal receiving data through NR; the terminal sending data through NR will interfere with the terminal receiving data through LTE.

[0003] In order to avoid the above problems, the currently adopted solution is that the base station schedules the uplink transmission resources and downlink transmission resources of the terminal, thereby preventing the terminal from simultaneously performing uplink and downlink transmission of data on resources that interfere with each other. However, this solution will increase the processing load of the base station. Summary of the invention

[0050] During the period of smooth transition from LTE to 5G, there will be a stage where LTE and 5G coexist. In this stage, there will be two wireless access methods and two core networks coexisting. The two wireless access methods include LTE access method and NG access; and the two core networks include packet core network (EPC, Evolved Packet Core) and next generation core network (NGCN, Next Generation Core). Based on the above two access methods, the corresponding base stations may include: evolved base stations (eNB, evolved Node B) and gNB. Therefore, the network side base stations involved in the embodiments of the present invention may include the above two base stations, and it can be understood that they may also include the types of base stations that appear in the subsequent technological development process. The embodiments of the present invention do not specifically limit this.

[0051] Figure 1 FIG. 2 shows a non-typical application scenario of an embodiment of the present invention, where a terminal 1 is within the coverage of a base station 2. Figure 1 The ellipse shown in FIG; the base station 2 allocates uplink transmission resources and downlink transmission resources to the terminal 1. The uplink transmission is as follows: Figure 1 As shown by the solid arrow in the middle, the downlink transmission is as follows Figure 1 As shown by the dashed arrow. Figure 1 It can be understood that the base station 2 can be an eNB or a gNB, or a network device for wireless access of a real-line terminal that appears in the subsequent process of technology development. This embodiment of the present invention will not be described in detail.

[0052] based on Figure 1 The application scenario shown is used to illustrate the technical solution of the embodiment of the present invention.

[0053] Embodiment 1

[0054] See also Figure 2 , which shows a transmission resource scheduling method provided by an embodiment of the present invention, the method comprising:

[0055] S201: Receive a candidate uplink data sending resource, or receive a candidate downlink data receiving resource;

[0056] S202: Selecting an uplink transmission resource for uplink data transmission from the candidate uplink data transmission resources according to the downlink transmission resource, or determining a transmission resource for downlink data reception from the candidate downlink data reception resources according to the uplink transmission resource.

[0057] Figure 2 The technical solution shown can be applied to Figure 1 The terminal in the scenario shown may include, for example, a user equipment (UE), a mobile station (MS), a mobile wireless device, a mobile communication device, a tablet computer, a handheld device, or other types of wireless devices during the specific implementation process, which will not be described in detail in this embodiment.

[0058] Since the existing interference at this stage is the interference of uplink transmission resources on downlink reception resources and the interference of downlink reception resources on uplink transmission resources, Figure 2 The technical solution shown is that the terminal selects the transmission resource for uplink data transmission based on the downlink transmission resource from the candidate uplink data transmission resources, and then selects the transmission resource for uplink data transmission that can avoid interference with the downlink transmission resource; or the terminal selects the transmission resource for downlink data transmission based on the uplink transmission resource from the candidate downlink data receiving resources, and then selects the transmission resource for downlink data transmission that can avoid interference with the uplink transmission resource. Therefore, the base station does not need to perform scheduling, which reduces the processing load of the base station.

[0059] for Figure 2 The technical solution shown in the figure, in a possible implementation manner, before S201, may also include:

[0060] Send a resource request indication; the resource request indication is used to request the base station to allocate the candidate uplink data sending resource or the candidate downlink data receiving resource.

[0061] Specifically, in this implementation, the resource request indication can be reported in the form of signaling, and the specific format of the reported signaling can be physical layer signaling, MAC layer signaling or RRC side signaling. The specific format is not repeated here. In addition, corresponding to sending the resource request indication, a frequency identifier or a time identifier can also be sent, wherein the frequency identifier or the time identifier is used to eliminate the uplink data sending resources corresponding to the frequency identifier or the time identifier when determining the candidate uplink data sending resources; or, the frequency identifier or the time identifier is used to eliminate the downlink data receiving resources corresponding to the frequency identifier or the time identifier when determining the candidate downlink data receiving resources.

[0062] It should be noted that, for this implementation method, after the terminal learns the downlink transmission resources, in order to avoid interference of the uplink data sending resources with the downlink transmission resources, the terminal can send a resource request indication in the form of a reporting signaling, so that the network side, such as the base station, can send down candidate uplink data sending resources, so that the terminal itself can select the transmission resource for uplink data sending from the candidate uplink data sending resources; or, after learning the uplink transmission resources, the terminal can send a resource request indication in the form of a reporting signaling, in order to avoid interference of the downlink data receiving resources with the uplink transmission resources, so that the network side, such as the base station, can send down candidate downlink data receiving resources, so that the terminal itself can select the transmission resource for downlink data receiving from the candidate downlink data receiving resources.

[0063] In addition, it should be noted that the network side can also determine whether the uplink data transmission resources will interfere with the downlink transmission resources. Taking the network side device as a base station as an example, when the terminal reports the uplink data to be transmitted, the resource request indication can be carried by an uplink scheduling request (SR, Scheduling Request) or a buffer status report (BSR, Buffer Status Report). After obtaining the SR or BSR, the base station can calculate which frequency bands of uplink data transmission resources are used for uplink data transmission, which will cause interference to downlink data transmission.

[0064] for Figure 2 In another possible implementation of the technical solution shown, the candidate uplink data transmission resources include: uplink data transmission resources with interference possibility, or uplink data transmission resources that are sure to interfere, or uplink data transmission resources that are not interfered;

[0065] The candidate downlink data receiving resources include: downlink data receiving resources with the possibility of interference, or downlink data receiving resources that are sure to interfere, or downlink data receiving resources that are not interfering.

[0066] That is to say, after obtaining the above-mentioned candidate uplink data sending resources, the terminal can select at least one from them as the transmission resource for uplink data sending; or after obtaining the above-mentioned candidate downlink data receiving resources, the terminal can select at least one from them as the transmission resource for downlink data receiving.

[0067] for Figure 2 In another possible implementation of the technical solution shown, determining the transmission resource for uplink data transmission from the candidate uplink data transmission resources according to the downlink transmission resource may specifically include:

[0068] Determine interference conditions according to the downlink transmission resources and the candidate uplink data sending resources;

[0069] According to the interference situation, a preset number of transmission resources for uplink data transmission are selected for data transmission.

[0070] Correspondingly, for Figure 2 In another possible implementation of the technical solution shown,

[0071] Selecting a transmission resource for receiving downlink data from the candidate downlink data receiving resources according to the uplink transmission resource includes:

[0072] Determine interference conditions according to the uplink transmission resources and the candidate downlink data reception resources;

[0073] According to the interference situation, a preset number of transmission resources for receiving downlink data are selected for data transmission.

[0074] Specifically, the interference situation can be determined according to a preset interference detection strategy through the downlink transmission resource and each uplink data sending resource in the candidate uplink data sending resource, or through the uplink transmission resource and each downlink data receiving resource in the candidate downlink data receiving resource according to the preset interference detection strategy. For example, the preset interference detection strategy may be a frequency detection strategy. That is to say, in a specific implementation, determining the interference situation according to the downlink transmission resource and the candidate uplink data sending resource may include:

[0075] The terminal compares the frequency band where the downlink transmission resource is located with the frequency band where the candidate uplink data transmission resource is located, and determines whether there is interference between the downlink transmission resource and each of the candidate uplink data transmission resources; wherein the interference includes cross-modulation interference, harmonic interference and harmonic mixing interference. It can be understood that when the frequency band difference is greater than the preset difference threshold, it can be considered that the candidate uplink data transmission resource has less interference on the downlink transmission resource; and when the frequency band difference is less than the preset difference threshold, it can be considered that the candidate uplink data transmission resource has greater interference on the downlink transmission resource, and the smaller the frequency band difference, the greater the interference.

[0076] Correspondingly, determining the interference situation according to the uplink transmission resource and the candidate downlink data reception resource includes:

[0077] Compare the frequency band where the uplink transmission resource is located with the frequency band where the candidate downlink data receiving resources are located to determine whether there is interference between the uplink transmission resource and each of the candidate downlink data receiving resources; wherein the interference includes cross-modulation interference, harmonic interference and harmonic mixing interference.

[0078] It should be noted that, in addition to frequency detection, other interference detection methods may be used to determine the interference of candidate uplink data sending resources on downlink transmission resources or candidate downlink data receiving resources on uplink transmission resources, which will not be elaborated in this embodiment.

[0079] This embodiment provides a method for scheduling transmission resources, wherein a terminal selects a transmission resource for uplink data transmission that can avoid interference with downlink transmission resources based on downlink transmission resources among candidate uplink data transmission resources; or a terminal selects a transmission resource for downlink data transmission that can avoid interference with uplink transmission resources among candidate downlink data receiving resources based on uplink transmission resources. Thus, scheduling is not required for a base station, and the processing load of the base station is reduced.

[0080] Embodiment 2

[0081] Based on the same inventive concept as the above embodiments, see Figure 3 , which shows a transmission resource scheduling method provided by an embodiment of the present invention, the method comprising:

[0082] S301: Allocate candidate uplink data sending resources based on downlink transmission resources, or allocate candidate downlink data receiving resources based on uplink transmission resources;

[0083] S302: Send the candidate uplink data sending resource or the candidate downlink data receiving resource to a terminal;

[0084] The candidate uplink data sending resources are used by the terminal to select and obtain transmission resources for uplink data sending, and the candidate downlink data receiving resources are used by the terminal to select and obtain transmission resources for downlink data receiving.

[0085] Figure 3 The technical solution shown can be applied to Figure 1 The base station in the scenario shown may be an eNB, a gNB, or a network device for wireless access of a real-line terminal that appears in the subsequent process of technological development. This embodiment will not be described in detail.

[0086] Figure 3 In the technical solution shown, since the base station sends candidate uplink data sending resources or candidate downlink data receiving resources to the terminal so that the terminal can select transmission resources for uplink data sending or transmission resources for downlink data reception, there is no need for the base station to schedule the uplink or downlink transmission resources of the terminal. Instead, the terminal itself performs the selection and scheduling, thereby reducing the processing load of the base station.

[0087] for Figure 3 The technical solution shown in the figure, in a possible implementation manner, before allocating candidate uplink data sending resources based on downlink transmission resources, or allocating candidate downlink data receiving resources based on uplink transmission resources, may also include:

[0088] Receive a resource request indication; the resource request indication is used to request allocation of a candidate uplink data sending resource or the candidate downlink data receiving resource.

[0089] Specifically, the resource request indication can be reported in the form of signaling, such as physical layer signaling, MAC layer signaling or RRC side signaling. In addition, corresponding to receiving the resource request indication, a frequency identifier or a time identifier can also be received, wherein the frequency identifier or the time identifier is used to eliminate the uplink data sending resources corresponding to the frequency identifier or the time identifier when determining the candidate uplink data sending resources; or, the frequency identifier or the time identifier is used to eliminate the downlink data receiving resources corresponding to the frequency identifier or the time identifier when determining the candidate downlink data receiving resources.

[0090] It can be understood that in this implementation, after the terminal learns the downlink transmission resources, in order to avoid possible interference of the uplink data sending resources with the downlink transmission resources, the terminal can send a resource request indication in the form of reporting signaling, so that the base station can send candidate uplink data sending resources, so that the terminal itself can select the transmission resource for uplink data sending from the candidate uplink data sending resources; correspondingly, after learning the uplink transmission resources, the terminal can send a resource request indication in the form of reporting signaling, so that the base station can send candidate downlink data receiving resources, so that the terminal itself can select the transmission resource for downlink data receiving from the candidate downlink data receiving resources.

[0091] In addition, for Figure 3 In another possible implementation of the technical solution shown, the base station can also determine by itself whether the uplink data transmission resource will interfere with the downlink transmission resource. Therefore, allocating candidate uplink data transmission resources based on the downlink transmission resource includes:

[0092] Receive SR or BSR;

[0093] The uplink data transmission resources causing interference to the downlink transmission resources are obtained by calculation according to the SR or BSR;

[0094] The uplink data sending resources that interfere with the downlink transmission resources are eliminated from the candidate uplink data sending resources.

[0095] for Figure 3 In the technical solution shown, the candidate uplink data transmission resources include: uplink data transmission resources with interference possibility, or uplink data transmission resources that are sure to interfere, or uplink data transmission resources that are not interfered;

[0096] The candidate downlink data receiving resources include: downlink data receiving resources with the possibility of interference, or downlink data receiving resources that are sure to interfere, or downlink data receiving resources that are not interfering.

[0097] That is to say, after obtaining the candidate uplink data transmission resources or the candidate downlink data reception resources, the terminal can select at least one of them as a transmission resource for uplink data transmission or a transmission resource for downlink data reception. This avoids the scheduling of the base station and reduces the processing load of the base station.

[0098] Embodiment 3

[0099] Based on the same inventive concept as the above-mentioned embodiment, this embodiment describes the technical solution of the above-mentioned embodiment in detail through two specific examples.

[0100] Specific example 1

[0101] See also Figure 4 , which shows a specific process of a transmission resource scheduling method provided by an embodiment of the present invention, and the specific process may include:

[0102] S401: After obtaining downlink transmission resources, the terminal reports a resource request indication and a frequency identifier or a time identifier to the base station;

[0103] It should be noted that after the terminal learns about the downlink transmission resources, it can find that the uplink data transmission resources may interfere with the downlink transmission resources. Therefore, the terminal can encapsulate the resource request indication in the physical layer signaling, MAC layer signaling or RRC layer signaling and send it to the base station. The resource request indication is used to request the base station to allocate candidate uplink data transmission resources. The frequency identifier or time identifier is used by the base station to eliminate the uplink data transmission resources corresponding to the frequency identifier or time identifier when allocating the candidate uplink data transmission resources, thereby avoiding the base station from sending the uplink data transmission resources corresponding to the frequency identifier or time identifier to the terminal.

[0104] S402: The base station allocates candidate uplink data transmission resources based on the downlink transmission resources, the resource request indication, and the frequency identifier or the time identifier;

[0105] Specifically, the base station can obtain available uplink data sending resources according to the resource request indication, and then eliminate the uplink data sending resources corresponding to the frequency identifier or time identifier from the available uplink data sending resources, and finally generate candidate uplink data sending resources allocated to the terminal from the eliminated uplink data sending resources according to the downlink transmission resources.

[0106] In this example, the candidate uplink data transmission resources may include: uplink data transmission resources with the possibility of interference, or uplink data transmission resources that are sure to interfere, or uplink data transmission resources that are not interfering.

[0107] S403: The base station sends the candidate uplink data sending resource to the terminal;

[0108] S404: The terminal compares the frequency band where the downlink transmission resource is located with the frequency band where the candidate uplink data sending resource is located, and determines whether there is interference between the downlink transmission resource and each of the candidate uplink data sending resources;

[0109] The interference includes cross-modulation interference, harmonic interference and harmonic mixing interference.

[0110] S405: The terminal selects a transmission resource for uplink data transmission from the candidate uplink data transmission resources according to the preset number and the determined interference situation.

[0111] In this example, the terminal discovers the interference problem with the downlink transmission resources. Therefore, the base station allocates candidate uplink data sending resources to the terminal according to the resource request indication reported by the terminal. The terminal then selects uplink transmission resources from them, eliminating the need for scheduling by the base station, thereby reducing the processing load of the base station.

[0112] Combination Figure 4 The scheme shown, see Figure 5 In the resource diagram shown in FIG. 1 , there are 15 blocks on the left side of the arrow, representing 15 resource blocks, and the candidate uplink data transmission resources are represented by resource blocks filled with slashes; when the candidate uplink data transmission resources are sent to the terminal, the terminal will select an uplink transmission resource from them, such as Figure 5 As shown on the right side of the middle arrow, the black-marked resource block is one of the original candidate uplink data sending resources. However, the terminal eliminates the uplink data sending resource represented by the black-marked resource block from the candidate uplink data sending resources because the uplink data sending resource may interfere with the downlink data transmission. Therefore, the terminal uses the uplink data sending resource represented by the resource block filled with slashes on the right side of the arrow as the transmission resource for uplink data transmission.

[0113] Specific example 2

[0114] In this specific example, the base station discovers the problem of interference with downlink transmission resources, so see Figure 6 , this specific example may include:

[0115] S601: The terminal sends an SR or a BSR to the base station;

[0116] S602: The base station calculates, according to the SR or BSR, uplink data transmission resources that interfere with the downlink transmission resources;

[0117] S603: The base station removes the uplink data transmission resources that interfere with the downlink transmission resources from the candidate uplink data transmission resources.

[0118] S604: The base station sends the candidate uplink data sending resource to the terminal;

[0119] In this example, the candidate uplink data transmission resources may include: uplink data transmission resources with the possibility of interference, or uplink data transmission resources that are sure to interfere, or uplink data transmission resources that are not interfering.

[0120] S605: The terminal selects a transmission resource for uplink data transmission from the candidate uplink data transmission resources according to the downlink transmission resource.

[0121] Specifically, the specific implementation process of S605 is similar to Figure 4S404 and S405 described in are the same, and will not be described in detail in this specific example.

[0122] It should be noted that for S601 to S603, when the terminal reports the uplink data to be transmitted, it will send an uplink scheduling request (SR, Scheduling Request) to the base station, and will also report a buffer status report (BSR, Buffer Status Report). After obtaining the SR or BSR, the base station can calculate which frequency bands of uplink data sending resources are used for uplink data transmission, which will cause interference to downlink data transmission.

[0123] In this example, the base station discovers the problem of interference with the downlink transmission resources. When the base station discovers that interference occurs with the downlink transmission resources, it sends candidate uplink data sending resources to the terminal, so that the terminal selects the uplink transmission resources from the candidate uplink data sending resources, avoiding scheduling by the base station and reducing the processing load of the base station.

[0124] The above two examples illustrate the process of a terminal selecting a transmission resource for uplink data transmission from candidate uplink data transmission resources through specific processes. The following illustrates the process of a terminal selecting a transmission resource for downlink data reception from candidate downlink data reception resources through specific examples.

[0125] Specific example three

[0126] See also Figure 7 , which shows a specific process of a transmission resource scheduling method provided by an embodiment of the present invention, and the specific process may include:

[0127] S701: After obtaining uplink transmission resources, the terminal reports a resource request indication and a frequency identifier or a time identifier to the base station;

[0128] It should be noted that after the terminal learns about the uplink transmission resources, it can find that the downlink data reception resources may interfere with the uplink transmission resources. Therefore, the terminal can encapsulate the resource request indication in the physical layer signaling, MAC layer signaling or RRC layer signaling and send it to the base station. The resource request indication is used to request the base station to allocate candidate downlink data reception resources. The frequency identifier or time identifier is used by the base station to eliminate the downlink data reception resources corresponding to the frequency identifier or time identifier when allocating the candidate downlink data reception resources, thereby avoiding the base station from sending the downlink data reception resources corresponding to the frequency identifier or time identifier to the terminal.

[0129] S702: The base station allocates candidate downlink data reception resources based on the uplink transmission resources, the resource request indication, and the frequency identifier or the time identifier;

[0130] Specifically, the base station can obtain available downlink data reception resources according to the resource request indication, and then eliminate the downlink data reception resources corresponding to the frequency identifier or time identifier from the available downlink data reception resources, and finally generate candidate downlink data reception resources allocated to the terminal from the eliminated downlink data reception resources according to the uplink transmission resources.

[0131] In this example, the candidate downlink data receiving resources include: downlink data receiving resources with the possibility of interference, or downlink data receiving resources that are sure to interfere, or downlink data receiving resources that are not interfering.

[0132] S703: The base station sends the candidate downlink data receiving resource to the terminal;

[0133] S704: The terminal compares the frequency band where the uplink transmission resource is located with the frequency band where the candidate downlink data receiving resource is located, and determines whether there is interference between the uplink transmission resource and each of the candidate downlink data receiving resources;

[0134] Wherein, the interference includes cross-modulation interference, harmonic interference and harmonic mixing interference;

[0135] S705: The terminal selects a transmission resource for downlink data reception from candidate downlink data reception resources according to a preset number and a determined interference condition.
