Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a carrier aggregation asymmetric prediction carrier indication and allocation method, base station, terminal, device, communication equipment, computer-readable storage medium and computer program product. Background Art

[0002] With the development of wireless communication technology, LTE (Long Term Evolution) and LTE-Advanced (LTE evolution) of 3GPP (3rd Generation Partnership Project) and the latest 5G NR (New Radio) technology have emerged, which greatly improve the bandwidth of wireless communication.

[0003] At present, CC (Carrier Congregate) is a key technology to support larger bandwidth in future wireless communication systems. Carriers of different types and / or sizes are aggregated to form a carrier with larger bandwidth. In the carrier aggregation system of the 5G communication system, when the DCI (Down Link Control Information) of the UE (user end) control channel is scrambled together with the C-RNTI (Cell Radio Network Temporary Identity) in the UE special search interval, the CIF (Carrier Indicator Field) is preferably included in a simple DCI design. However, due to different carrier bandwidths / types / sizes or transmission modes, the payload type / size of multiple aggregated carriers is unclear, resulting in inconsistent interpretation of scheduling signaling between gNB (gNodeB, full name the next Generation Node B, the next generation base station, i.e., 5G base station) and UE, resulting in unclear scheduling during the RRC (Radio Resource Control) reconfiguration cycle.

[0090] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0091] The carrier aggregation asymmetric prediction carrier indication and allocation method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. Among them, the terminal 102 (such as the user end UE in the embodiment below) communicates with the base station 101 (such as the gNB in ​​the embodiment below) through a wireless network. The base station 101 completes the uplink and downlink component carrier resource allocation of the terminal 101 through the carrier aggregation asymmetric prediction carrier strategy indicator; wherein the carrier aggregation asymmetric prediction carrier strategy indicator is set on the downlink control information of the physical downlink control channel, and is used to perform component carrier auxiliary information and service prediction on all component carriers. Then, the component carrier resource allocation results of the uplink and downlink are sent to the terminal 102, so that the terminal 102 completes the carrier aggregation according to the component carrier resource allocation results of the uplink and downlink. Among them, the terminal 102 can be but not limited to various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices, and the Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head mounted device may be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The base station 101 may be a gNB (5G base station).

[0092] In an exemplary embodiment, Figure 2 As shown, a carrier aggregation asymmetric prediction carrier indication and allocation method is provided, and the method is applied to Figure 1 The base station in FIG. 1 is taken as an example to illustrate, including the following steps 201 to 202. Among them:

[0093] Step 201: complete the allocation of component carrier resources of the terminal uplink and downlink through carrier aggregation asymmetric prediction carrier strategy indicator.

[0094] In this embodiment, the carrier aggregation asymmetric prediction carrier strategy indicator is set on the downlink control information (DCI) of the physical downlink control channel (PDCCH) to perform component carrier auxiliary information and service prediction on all component carriers.

[0095] Exemplarily, component carrier auxiliary information and service prediction can be performed for existing component carriers, new / invalid component carriers, etc. according to the spectrum / frequency band used by the operator, interference type and interference level, radio resource control (RRC) resource reallocation signaling overhead and complexity, etc.

[0096] For example, Figure 3As shown, the fields of the carrier aggregation asymmetric prediction carrier strategy indicator are displayed, wherein the carrier aggregation asymmetric prediction carrier strategy indicator includes: UE payload classification field, gNB / UE payload size confirmation field, interference measurement and prediction field, asymmetric component carrier prediction strategy field, gNB / UE component carrier mapping field, and asymmetric component carrier prediction feedback field.

[0097] It should be noted that this embodiment provides a possible configuration example of a carrier aggregation asymmetric prediction carrier strategy indicator. In actual application, it can also be divided into different fields (for example, different field names and different numbers) as needed, and the function of each field is defined. During program operation, the definition of the field name does not affect the actual function performed.

[0098] The UE payload classification field is used to determine the payload type of the terminal.

[0099] In this embodiment, the payload type of the UE includes but is not limited to: uplink (UL) component carrier resource enhancement type, downlink (DL) component carrier resource enhancement type, uplink (UL) / downlink (DL) component carrier resource balance type, uplink (UL) / downlink (DL) component carrier resource unbalanced type. This enables the gNB to understand and confirm the component carrier allocation status related to the payload type of the UE, so that the gNB can complete the component carrier allocation for the UE to realize carrier aggregation.

[0100] Among them, the gNB / UE payload size confirmation field is used to determine the payload size that the terminal should actually use under the corresponding payload type.

[0101] In this embodiment, the setting of the gNB / UE payload size confirmation field can facilitate the gNB to select component carrier resources to complete the component carrier allocation of the UE; at the same time, the gNB must confirm the payload size that can be carried by the component carrier resources that it actually owns and can control according to the component carrier, so as to select appropriate component carrier resources for the UE to complete carrier aggregation.

[0102] The interference measurement and prediction field is used to measure the interference type and interference intensity at the corresponding position in the macro cell where the terminal is located.

[0103] In this embodiment, when allocating component carriers to UEs, gNB can avoid selecting component carriers that match the main interference type and interference intensity of UEs, thereby improving the carrying capacity of component carrier resources allocated by gNB to UEs, and further improving the service throughput on component carrier resources allocated by gNB. For example, gNB completes interference prediction for UEs, and when other UEs appear in the location of the macro cell that gNB has measured, gNB will not first measure the interference type and interference intensity of UEs, but will use interference prediction to predetermine the interference type and interference intensity of the location in this macro cell.

[0104] Exemplarily, the gNB determines various types of interference generated within the cell / between cells, at the cell edge, etc., including but not limited to: inter-subband link interference (CLI) between gNBs, inter-subband link interference (CLI) between UEs within the cell, inter-subband link interference (CLI) between UEs between cells, interference from UEs between cells to gNBs of other adjacent cells, interference from gNBs between cells to UEs of adjacent cells, etc.

[0105] For example, Fig.11 As shown, interference type 1: Inter-subband cross-link interference (CLI) between gNBs refers to the interference of the gNB receiver from another gNB transmitter. Interference type 2: Inter-subband cross-link interference (CLI) between UEs in a cell refers to the impact of UE transmission on non-overlapping resources in the same cell on another UE. Interference type 3: Inter-subband cross-link interference (CLI) between UEs in an inter-cell refers to the impact of UE transmission on non-overlapping resources in an adjacent cell on another UE. Interference type 4: Inter-cell UE interference to gNBs in other adjacent cells refers to the interference of UE transmission in one cell to the uplink (UL) reception of gNBs in other cells. Interference type 5: Inter-cell gNB interference to UEs in adjacent cells refers to the downlink (DL) reception interference of gNBs in one cell to UEs in other cells. Interference type 6: New strong inter-cell interference caused by cell identity conflict means that when there is a cell identity conflict, the UE at the cell edge is subject to strong inter-cell interference caused by the gNB with the same identity in the adjacent cell; due to the cell identity conflict, multiple gNBs use different interference suppression methods for the same UE at different locations in different cells, resulting in the UE being subject to different types of strong interference at the same time.

[0106] The asymmetric component carrier prediction strategy field is used to predetermine auxiliary information, as well as operator spectrum / frequency band, component carrier service / interference prediction, to complete asymmetric prediction allocation / mapping of component carriers of the terminal.

[0107] In this embodiment, the asymmetric component carrier prediction strategy field (for example, may include: auxiliary information, operator spectrum / frequency band, component carrier service / interference prediction, etc.) is used for pre-determined auxiliary information. The auxiliary information may include: carrier indicator field (CIF) composition and transmission method, number of downlink control information (DCI) formats, radio resource control (RRC) reconfiguration component carrier resources and mapping relationship, link correspondence between uplink and downlink control channels, each physical downlink shared channel (PDSCH, Physical Downlink Shared Channel) / physical uplink shared channel (PUSCH, Physical Uplink Shared Channel) component carrier scheduling method, and the way in which downlink control channels are simultaneously detected in the search interval, etc.

[0108] Among them, the gNB / UE component carrier mapping field is used to determine the mapping relationship between the carrier indicator field and the component carrier for all component carrier resources that can be scheduled by the base station, and during the wireless resource control reconfiguration cycle, the allocation and mapping of component carrier resources and the prediction method jointly used by the asymmetric component carrier prediction strategy field are adopted to mark all component carriers according to the information determined by the asymmetric component carrier prediction strategy field.

[0109] In an optional embodiment, when the base station or the terminal parses the scheduling signaling of the component carrier, the base station sets the component carrier mapping relationship prediction mapping indication subfield on the carrier indicator field, and determines the mapping relationship of all allocated component carriers within the wireless resource control reconfiguration cycle to obtain the component carrier resource allocation results of the terminal uplink and downlink.

[0110] For example, Figure 4 As shown, in Figure 4 The composition of the component carrier mapping relationship prediction mapping indication subfield is shown in, which may include: operator band / frequency band identification byte, component carrier payload type identification byte, component carrier payload size identification byte, component carrier interference type and interference intensity identification byte, component carrier adjustment step and precision selection identification byte.

[0111] Exemplarily, the operator band / frequency band identification byte is used to identify the basic band / frequency band information of all component carriers. If the basic band / frequency band information does not match, the gNB cannot allocate these component carriers to form carrier aggregation.

[0112] Exemplarily, the component carrier payload type identification byte is used to determine the payload type of all component carriers, including but not limited to: uplink (UL) component carrier resource enhancement type, downlink (DL) component carrier resource enhancement type, uplink (UL) / downlink (DL) component carrier resource balance type, uplink (UL) / downlink (DL) component carrier resource unbalanced type, etc. Its main purpose is to enable the gNB to classify and identify the component carriers related to the payload type. Normally, the gNB will only select the component carriers with the same component carrier payload type identification to complete carrier aggregation.

[0113] Exemplarily, the component carrier payload size identification byte is used to determine the payload size so that the gNB can select the component carrier resources to complete the component carrier allocation. Usually, when the gNB selects the payload size of the component carrier, it allocates it according to the uplink (UL) / downlink service conditions. The allocation strategies include: symmetric, balanced, asymmetric, etc.

[0114] Exemplarily, the component carrier interference type and interference intensity identification byte is used by the gNB to determine the various types of interference generated within the cell / between cells, at the cell edge, etc. of the component carrier. The various types of interference include but are not limited to: inter-subband cross-link interference (CLI) between gNBs, inter-subband cross-link interference (CLI) between UEs within a cell, inter-subband cross-link interference (CLI) between UEs between cells, interference from UEs between cells to gNBs in other adjacent cells, and interference from gNBs between cells to UEs in adjacent cells. Specifically, when the gNB identifies the component carrier interference type and interference intensity, it will only identify the component carrier that can resist a specific type of interference and interference intensity and achieve a good carrier aggregation effect. Normally, the gNB will only allocate component carriers with the same interference type and interference intensity to complete carrier aggregation.

[0115] Exemplarily, the component carrier adjustment step and precision selection identification byte is used for the component carrier adjustment step and precision when allocating component carrier resources, including: the component carrier starting position determined by the gNB when allocating the component carrier (mainly used to determine the position of the unallocated component carrier), the component carrier adjustment step (the minimum unit used to allocate the component carrier, mainly used to select the starting position of the component carrier), and the component carrier adjustment precision (used to set the maximum size range when allocating the component carrier, including: component carrier allocation redundancy to ensure that the gNB can allocate matching carrier resources). Through the component carrier starting position and adjustment step, the gNB can scan all the component carrier resources to be allocated. According to the component carrier adjustment precision, the gNB completes all component carrier allocations through continuous and / or non-continuous component carrier combinations. Among them, the setting of the component carrier adjustment step and precision needs to be determined according to the actual situation of the macro cell where the gNB is located. If the component carrier step is small, the gNB can accurately adjust the component carrier resources at a small step to avoid the waste of component carrier resources caused by too large a step. This method requires frequent signaling interactions between the gNB and / or UE and a longer component carrier resource determination time. If the component carrier step size is large, the gNB can complete the component carrier resource allocation with less frequent signaling interactions between gNB and / or UE and the component carrier resource determination time. However, this method may waste component carrier resources at a large step size. Among them, the component carrier adjustment accuracy needs to be determined according to the actual situation of the macro cell where the gNB is located. If the component carrier adjustment accuracy is high, the gNB can accurately match the number of component carriers required by the UE. However, this method will increase the complexity of gNB component carrier scheduling. If the component carrier adjustment accuracy is low, that is, there is redundancy in component carrier allocation, the gNB can select matching component carrier resources in all component carrier ranges between the exact usage value and the redundant value of the component carrier in all component carrier allocations. This significantly reduces the complexity of gNB component carrier resource allocation, but also increases the waste of component carrier resources.

[0116] The asymmetric component carrier prediction feedback field is used to complete signaling interaction and status feedback at different stages between the base station and the terminal.

[0117] Step 202: Send the uplink and downlink component carrier resource allocation results to the terminal.

[0118] In this embodiment, the base station sends the component carrier resource allocation result of the uplink and downlink to the terminal, so that the terminal completes carrier aggregation according to the component carrier resource allocation result of the uplink and downlink.

[0119] In the above-mentioned carrier aggregation asymmetric prediction carrier indication and allocation method, a carrier aggregation asymmetric prediction carrier strategy indicator is set on the downlink control information of the physical downlink control channel to perform component carrier auxiliary information and service prediction on all component carriers, so that the base station can understand and confirm the component carrier allocation related to the terminal and the payload type / size, and effectively avoid scheduling ambiguity during the RRC reconfiguration cycle. The component carrier resource allocation results of the uplink and downlink are sent to the terminal so that the terminal completes carrier aggregation according to the component carrier resource allocation results of the uplink and downlink. Thereby, when allocating component carriers to the terminal, the base station can avoid selecting a component carrier that matches the main interference type and interference intensity of the terminal, thereby improving the carrying capacity of the component carrier resources allocated by the base station to the terminal, and then improving the service throughput on the component carrier resources allocated by the base station.

[0120] In another exemplary embodiment, Figure 5 As shown, a carrier aggregation asymmetric prediction carrier indication and allocation method is provided, and the method is applied to Figure 1 The base station in FIG. 1 is taken as an example to illustrate, including the following steps 501 to 504. Among them:

[0121] Step 501: complete the allocation of component carrier resources of the terminal uplink and downlink through carrier aggregation asymmetric prediction carrier strategy indicator.

[0122] Step 502: Send the uplink and downlink component carrier resource allocation results to the terminal.

[0123] For the specific implementation process and technical effects of steps 501 to 502 in this embodiment, please refer to Figure 2 The descriptions of steps 201 to 202 in the method are not repeated here.

[0124] Step 503: predict the information of the mapping indication subfield according to the component carrier mapping relationship, predict the component carrier allocation position of the terminal, and allocate corresponding component carrier resources.

[0125] In this embodiment, when a new terminal accesses a base station within a macro cell, and / or the terminal needs to change the component carrier allocation and mapping due to changes in its own performance parameters, the information of the mapping indication subfield can be predicted based on the component carrier mapping relationship to predict the component carrier allocation position of the terminal and allocate the corresponding component carrier resources.

[0126] Exemplarily, when the gNB / UE parses the scheduling signaling of the component carrier, the gNB sets the component carrier mapping relationship prediction mapping indication subfield in the carrier indicator field (CIF), and determines the mapping relationship of all the allocated component carriers during the radio resource control (RRC) reconfiguration cycle. At the same time, when a new UE accesses the gNB in ​​the macro cell and / or the UE needs to change the component carrier allocation and mapping due to changes in its own performance parameters, the gNB first predicts the UE's component carrier allocation position based on the information of the component carrier mapping relationship prediction mapping indication subfield and allocates the corresponding component carrier resources, and then allocates the corresponding component carrier resources.

[0127] Step 504: Send the reallocated component carrier resources to the terminal.

[0128] In this embodiment, the base station sends the reallocated component carrier resources to the terminal, so that the terminal performs carrier aggregation according to the reallocated component carrier resources.

[0129] In this embodiment, when a new terminal accesses a base station in a macro cell, and / or when the terminal needs to change the component carrier allocation and mapping due to changes in its own performance parameters, the component carrier allocation position of the terminal can be predicted based on the information of the mapping indication subfield predicted by the component carrier mapping relationship, and the corresponding component carrier resources can be allocated; the reallocated component carrier resources are sent to the terminal, so that the terminal performs carrier aggregation according to the reallocated component carrier resources. Therefore, when the terminal in the macro cell changes, the allocation of component carrier resources can be adjusted in time, thereby improving the carrying capacity of the component carrier resources allocated by the base station to the terminal, and further improving the service throughput on the component carrier resources allocated by the base station.

[0130] In yet another exemplary embodiment, Figure 6 As shown, a carrier aggregation asymmetric prediction carrier indication and allocation method is provided, and the method is applied to Figure 1 The base station in FIG. 1 is taken as an example to illustrate, and the method includes the following steps 601 to 608. Among them:

[0131] Step 601, completing the allocation of component carrier resources of the terminal uplink and downlink through carrier aggregation asymmetric prediction carrier strategy indicator.

[0132] Step 602: Send the uplink and downlink component carrier resource allocation results to the terminal.

[0133] For the specific implementation process and technical effects of steps 601 to 600 in this embodiment, please refer to Figure 2 The descriptions of steps 201 to 202 in the method are not repeated here.

[0134] Step 603: receiving the component carrier resource allocation result fed back by the terminal.

[0135] In this embodiment, the component carrier resource allocation result is used to indicate whether the terminal successfully completes carrier aggregation by applying the allocated component carrier resources.

[0136] Step 604, determining whether the result of the component carrier resource allocation is successful, if so, executing step 605, if not, returning to executing step 601.

[0137] In this embodiment, if the component carrier resource allocation result is a failure, the component carrier resources need to be reallocated.

[0138] Exemplarily, if the UE successfully completes carrier aggregation using the allocated component carrier resources, the UE will provide feedback to the gNB that the allocation of the component carrier resources is successful. If the UE fails to complete carrier aggregation using the allocated component carrier resources, for example, due to: mismatch of operator frequency bands / bands, asymmetric uplink (UL) and / or downlink (DL) services, main interference types and interference intensity of the gNB and / or UE causing the UE's throughput to fail to meet service requirements when completing carrier aggregation, etc., the UE will provide feedback to the gNB that the allocation of the component carrier resources is successful or unsuccessful.

[0139] Step 605 , measuring whether the throughput of the carrier aggregation of the terminal reaches a preset value, if so, the process ends, if not, executing step 606 .

[0140] Step 606: Initiate an interference measurement and prediction request to the terminal.

[0141] Step 607: receiving interference measurement and prediction results fed back by the terminal.

[0142] Step 608: reallocate component carrier resources according to the interference measurement and prediction results, and return to step 602.

[0143] In this embodiment, the component carrier resources are reallocated in any of the following ways:

[0144] The first method is to reallocate component carrier resources on the component carrier with the same conditions as the terminal as indicated in the component carrier mapping relationship prediction mapping indication subfield;

[0145] The second method is: initiating a measurement request to the terminal; receiving a measurement result fed back by the terminal; predicting an identifier of a mapping indication subfield according to the measurement result and a component carrier mapping relationship, and reallocating component carrier resources.

[0146] In this embodiment, the advantage of the first method is that the component carrier resources can be allocated without complex UE measurements, which significantly reduces the system overhead during signaling interaction. The disadvantage is that if the communication conditions of the UE on the macro cell are complex, the allocation of the component carrier may be completed after multiple component carrier resource reallocations. The advantage of the second method is that the component carrier resources are allocated according to the UE measurement results, which can reduce the number of component carrier resource allocation attempts. The disadvantage is that the gNB and / or UE need to complete the component carrier resource allocation through a large number of signaling interactions, which significantly increases the system overhead during signaling interaction.

[0147] In an exemplary embodiment, Figure 7 As shown, a carrier aggregation asymmetric prediction carrier indication and allocation method is provided, and the method is applied to Figure 1 The terminal in is taken as an example to illustrate, including the following steps 701 to 702. Among them:

[0148] Step 701: receiving the uplink and downlink component carrier resource allocation results sent by a base station.

[0149] In this embodiment, the component carrier resource allocation results of the uplink and downlink are obtained by the base station through the carrier aggregation asymmetric prediction carrier strategy indicator. The carrier aggregation asymmetric prediction carrier strategy indicator is set on the downlink control information of the physical downlink control channel, and is used to perform component carrier auxiliary information and service prediction for all component carriers.

[0150] Exemplarily, the carrier aggregation asymmetric prediction carrier strategy indicator includes: any one or any combination of: UE payload classification field, gNB / UE payload size confirmation field, interference measurement and prediction field, asymmetric component carrier prediction strategy field, gNB / UE component carrier mapping field, and asymmetric component carrier prediction feedback field.

[0151] Step 702: Carrier aggregation is completed according to the resource allocation results of the component carriers of the uplink and downlink.

[0152] In this embodiment, the terminal can effectively improve the user's data transmission rate and reduce latency by integrating wireless channel resources within or between frequency bands. Each carrier participating in carrier aggregation is called a component carrier (ComponentCarrier). Among all component carriers, the component carrier that carries signaling transmission and manages other component carriers is called a primary carrier (Primary cell). The secondary carrier (Secondary Cell) is used to expand bandwidth and increase rate. The primary carrier decides when to add or delete. In the 5G era, the number of carrier aggregations is 16. In FR1, 1.6GHz of bandwidth can be aggregated, and in FR2, the bandwidth that can be aggregated reaches 6.4GHz (16*400MHz).

[0153] In this embodiment, carrier aggregation is completed according to the uplink and downlink component carrier resource allocation results by receiving the uplink and downlink component carrier resource allocation results sent by the base station. The uplink and downlink component carrier resource allocation results are obtained by the base station through the carrier aggregation asymmetric prediction carrier strategy indicator, which is set on the downlink control information of the physical downlink control channel and is used to perform component carrier auxiliary information and service prediction on all component carriers. Therefore, when allocating component carriers to the terminal, the base station can avoid selecting a component carrier that matches the main interference type and interference intensity of the terminal, thereby improving the carrying capacity of the component carrier resources allocated by the base station to the terminal, and further improving the service throughput on the component carrier resources allocated by the base station.

[0154] In another exemplary embodiment, Figure 8 As shown, a carrier aggregation asymmetric prediction carrier indication and allocation method is provided, and the method is applied to Figure 1 The terminal in is taken as an example to illustrate, including the following steps 801 to 804. Among them:

[0155] Step 801: receiving uplink and downlink component carrier resource allocation results sent by a base station.

[0156] Step 802: Carrier aggregation is completed according to the resource allocation results of the component carriers of the uplink and downlink.

[0157] For the specific implementation process and technical effects of steps 801 to 800 in this embodiment, please refer to Figure 7 The descriptions of steps 701 to 702 in the method are not repeated here.

[0158] Step 803: Receive the reallocated component carrier resources sent by the base station.

[0159] In this embodiment, when a new terminal accesses a base station in a macro cell, and / or the terminal needs to change the component carrier allocation and mapping due to changes in its own performance parameters, the reallocated component carrier resources sent by the receiving base station are received, wherein the reallocated component carrier resources are reallocated after the base station predicts the information of the mapping indication subfield based on the component carrier mapping relationship, predicts the component carrier allocation position of the terminal, and predicts it.

[0160] In this embodiment, the component carrier mapping relationship prediction mapping indication subfield is set by the base station on the carrier indicator, and is used to determine the mapping relationships of all allocated component carriers within the wireless resource control reconfiguration cycle, and obtain the component carrier resource allocation results of the terminal uplink and downlink, wherein the component carrier mapping relationship prediction mapping indication subfield includes: any one or any combination of operator frequency band / frequency band identification byte, component carrier payload type identification byte, component carrier payload size identification byte, component carrier interference type and interference intensity identification byte, and component carrier adjustment step and precision selection identification byte.

[0161] Step 804: Carrier aggregation is performed according to the reallocated component carrier resources.

[0162] In this embodiment, when a new terminal accesses a base station in a macro cell, and / or when the terminal needs to change the component carrier allocation and mapping due to changes in its own performance parameters, the component carrier allocation position of the terminal can be predicted based on the information of the mapping indication subfield predicted by the component carrier mapping relationship, and the corresponding component carrier resources can be allocated; the reallocated component carrier resources are sent to the terminal, so that the terminal performs carrier aggregation according to the reallocated component carrier resources. Therefore, when the terminal in the macro cell changes, the allocation of component carrier resources can be adjusted in time, thereby improving the carrying capacity of the component carrier resources allocated by the base station to the terminal, and further improving the service throughput on the component carrier resources allocated by the base station.

[0163] In yet another exemplary embodiment, Fig. 9 As shown, a carrier aggregation asymmetric prediction carrier indication and allocation method is provided, and the method is applied to Figure 1 The terminal in the example is used to illustrate, including the following steps 901 to 903. Among them:

[0164] Step 901: receiving the component carrier resource allocation result of the uplink and downlink sent by the base station.

[0165] Step 902: Carrier aggregation is completed according to the resource allocation results of the component carriers of the uplink and downlink.

[0166] For the specific implementation process and technical effects of steps 901 to 900 in this embodiment, please refer to Figure 7 The descriptions of steps 701 to 702 in the method are not repeated here.

[0167] Step 903: Feedback the component carrier resource allocation result to the base station.

[0168] In this embodiment, if the component carrier resources allocated by the terminal application successfully complete carrier aggregation, the component carrier resource allocation result is fed back to the base station as success; if the component carrier resources allocated by the terminal application cannot complete carrier aggregation, the component carrier resource allocation result is fed back to the base station as failure.

[0169] In this embodiment, the terminal feeds back the component carrier resource allocation result to the base station in time, so that the base station can determine whether to reallocate the component carrier resources, thereby ensuring that the carrier aggregation of the terminal can be realized.

[0170] In a fourth exemplary embodiment, as Fig.10 As shown, a carrier aggregation asymmetric prediction carrier indication and allocation method is provided, and the method is applied to Figure 1 The terminal in is taken as an example to illustrate, including the following steps 1001 to 1004.

[0171] in:

[0172] Step 1001: receiving uplink and downlink component carrier resource allocation results sent by a base station.

[0173] Step 1002: Carrier aggregation is completed according to the resource allocation results of the component carriers of the uplink and downlink.

[0174] For the specific implementation process and technical effects of steps 1001 to 1002 in this embodiment, please refer to Figure 7 The descriptions of steps 701 to 702 in the method are not repeated here.

[0175] Step 1003: Receive a measurement request sent by the base station.

[0176] Step 1004: Feedback the measurement result to the base station.

[0177] In this embodiment, by feeding back the measurement result to the base station, the base station can predict the identifier of the mapping indication subfield according to the measurement result and the component carrier mapping relationship, and reallocate the component carrier resources. Exemplarily, the measurement result may include: interference measurement.

[0178] In an optional implementation, when the throughput on the carrier aggregation of the terminal does not reach a preset value, an interference measurement and prediction request sent by a base station is received; and the interference measurement and prediction results are fed back to the base station so that the base station reallocates the constituent carrier resources until the throughput reaches the preset value.

[0179] In this embodiment, when a new terminal accesses a base station in a macro cell, and / or when the terminal needs to change the component carrier allocation and mapping due to changes in its own performance parameters, the component carrier allocation position of the terminal can be predicted according to the information of the mapping indication subfield based on the component carrier mapping relationship, and the corresponding component carrier resources can be allocated; the reallocated component carrier resources are sent to the terminal, so that the terminal performs carrier aggregation according to the reallocated component carrier resources. In this way, the allocation of component carrier resources can be adjusted in time when the terminal in the macro cell changes.

[0180] In this embodiment, the measurement result of the terminal is regained by sending a request to the terminal, so that the component carrier resources can be reallocated according to the measurement result fed back by the terminal, thereby improving the carrying capacity of the component carrier resources allocated by the base station to the terminal, and further improving the service throughput on the component carrier resources allocated by the base station.

[0181] For example, Fig.11 As shown, the network architecture of multiple gNBs (5G base stations) and UEs (user terminals) is shown. Fig.12 The figure shows the signaling interaction between the base station and the terminal. Fig.12 As shown, the method in this embodiment may include the following steps:

[0182] Step 1201: The base station allocates uplink and downlink component carrier resources.

[0183] Step 1202: The base station sends a component carrier resource allocation result to the terminal.

[0184] Step 1203: The terminal performs carrier aggregation according to the result of resource allocation of constituent carriers.

[0185] Step 1204: The terminal feeds back the result of component carrier resource allocation to the base station.

[0186] In this embodiment, if the component carrier resources allocated by the terminal application successfully complete carrier aggregation, the component carrier resource allocation result is fed back to the base station as success; if the component carrier resources allocated by the terminal application cannot complete carrier aggregation, the component carrier resource allocation result is fed back to the base station as failure.

[0187] Step 1205: When a new terminal accesses the base station in the macro cell and / or the terminal needs to change the component carrier allocation and mapping due to changes in its own performance parameters, the base station reallocates the component carrier resources according to the information of the mapping indication field predicted by the component carrier mapping relationship.

[0188] Step 1206: The base station sends a new component carrier resource allocation result to the terminal.

[0189] Step 1207: The terminal performs carrier aggregation according to the new component carrier resource allocation result.

[0190] Step 1208: The base station sends a measurement request to the terminal.

[0191] Step 1209: The terminal feeds back the measurement result to the base station.

[0192] Step 1210: The base station predicts the identifier of the mapping indication subfield according to the measurement result and the component carrier mapping relationship, and reallocates the component carrier resources.

[0193] Step 1211: The base station measures the throughput of the terminal on the carrier aggregation.

[0194] In this embodiment, if the throughput on the carrier aggregation has not reached the preset value, step 1212 needs to be executed; if it has reached the preset value, the process ends.

[0195] Step 1212: The base station initiates an interference measurement and prediction request to the terminal.

[0196] Step 1213: The terminal feeds back the interference measurement and prediction results to the base station.

[0197] Step 1214: The base station reallocates component carrier resources according to the interference measurement and prediction results until the throughput reaches a preset value.

[0198] It should be noted that this embodiment does not limit the execution order of steps 1201 to 1214, and the specific implementation process and technical effects of steps 1201 to 1214 in this embodiment are described in detail in detail. Figure 2 to Figure 10 The relevant descriptions in each method embodiment will not be repeated here.

[0199] Exemplary, combined Fig.11 , Fig.12 , and examples are given for various different carrier aggregation asymmetric prediction strategies.

[0200] The first carrier aggregation asymmetric prediction strategy: uplink (UL) component carrier resource prediction enhanced type, may include the following steps A1 to A17:

[0201] Step A1: The gNB allocates the same matching component carrier resources for the UE's uplink (UL) and downlink (DL).

[0202] In this embodiment, when the UE's uplink (UL) service increases significantly, more component carrier resources need to be allocated to the uplink (UE). In order to improve the efficiency of component carrier resource allocation, the gNB can allocate the same matching component carrier resources to the UE's uplink (UL) and downlink (DL).

[0203] Step A2: The gNB will increase and / or decrease the component carrier resources of both uplink (UL) and downlink (DL).

[0204] Step A3: The gNB determines that the UE payload classification field is uplink (UL) component carrier resource prediction enhanced.

[0205] Step A4: The gNB determines the UE uplink (UL) payload size and modifies the gNB / UE payload size confirmation field.

[0206] Step A5: The gNB sets the interference measurement and prediction fields to the predicted interference type and interference strength value at the macro cell location where the UE is located.

[0207] Step A6: The gNB sets the operator band / frequency band identification byte that constitutes the carrier mapping relationship prediction mapping indication subfield to the current gNB's own identification.

[0208] Step A7: The gNB sets the component carrier payload type identification byte of the component carrier mapping relationship prediction mapping indication subfield to the uplink (UL) component carrier resource prediction enhanced type.

[0209] Step A8: The gNB sets the component carrier payload size identification byte of the component carrier mapping relationship prediction mapping indication subfield to the UE uplink (UL) payload size.

[0210] Step A9: The gNB sets the component carrier interference type and interference strength identification bytes of the component carrier mapping relationship prediction mapping indication subfield to the predicted interference type and interference strength value at the macro cell location where the UE is located.

[0211] Step A10: The gNB sets the component carrier adjustment step and precision selection identification bytes of the component carrier mapping relationship prediction mapping indication subfield to the values ​​preset by the gNB.

[0212] In this embodiment, if the gNB determines that the number of its unallocated carrier resources is large, the gNB will automatically adjust the component carrier adjustment step to a larger value, and at the same time, set the component carrier adjustment accuracy to a larger redundancy, so as to significantly reduce the component carrier resource allocation time while reducing the difficulty of the component carrier resource allocation algorithm.

[0213] Step A11: The gNB pre-allocates UE uplink (UL) component carrier resources based on the component carrier mapping relationship predicted mapping indication subfield.

[0214] Step A12: If the gNB predicts that the mapping indication subfield has not completed the UE uplink (UL) component carrier resource allocation based on the component carrier mapping relationship, the gNB adjusts the component carrier adjustment step and the precision selection identification byte to reallocate the component carrier resources until the UE uplink (UL) component carrier resource allocation is completed.

[0215] Step A13: The gNB predicts the mapping indication subfield and allocates UE downlink (DL) component carrier resources according to the component carrier mapping relationship.

[0216] Step A14: If the gNB has not completed the UE downlink (DL) component carrier resources, the gNB sequentially adjusts the component carrier interference type and interference intensity identification bytes and the operator band / frequency band identification bytes of the component carrier mapping relationship prediction mapping indication subfield to find the component carrier resources that match the UE uplink (UL) component carrier resources to complete the component carrier allocation.

[0217] In this embodiment, the gNB does not adjust the component carrier adjustment step and precision selection identification byte when allocating UE uplink (UL) component carrier resources to avoid mismatch between UE uplink (UL) and downlink (DL) component carrier resources.

[0218] Step A15: The UE completes carrier aggregation using the uplink (UL) and downlink (DL) carrier resources allocated by the gNB.

[0219] Step A16: The gNB measures the throughput on the carrier aggregation of the UE.

[0220] Step A17: If the throughput value preset by the gNB is not reached, the gNB requests the UE to initiate interference measurement and prediction and returns to step A5.

[0221] The second carrier aggregation asymmetric prediction strategy: downlink (DL) component carrier resource prediction enhanced type, may include the following steps B1 to B17:

[0222] Step B1: The gNB allocates the same matching component carrier resources for the UE's uplink (UL) and downlink (DL).

[0223] In this embodiment, when the uplink (UL) service of the UE increases significantly, more component carrier resources need to be allocated to the uplink (UE); and in order to improve the efficiency of component carrier resource allocation, the gNB can allocate the same matching component carrier resources to the UE's uplink (UL) and downlink (DL).

[0224] Step B2: The gNB will increase and / or decrease the component carrier resources for both uplink (UL) and downlink (DL).

[0225] Step B3: The gNB determines that the UE payload classification field is downlink (DL) component carrier resource prediction enhanced.

[0226] Step B4: The gNB determines the UE downlink (DL) payload size and modifies the gNB / UE payload size confirmation field.

[0227] Step B5: The gNB sets the interference measurement and prediction fields to the predicted interference type and interference strength value at the macro cell location where the UE is located.

[0228] Step B6: The gNB sets the operator band / frequency band identification byte that constitutes the carrier mapping relationship prediction mapping indication subfield to the current gNB's own identification.

[0229] Step B7: gNB sets the component carrier payload type identification byte of the component carrier mapping relationship prediction mapping indication subfield to downlink (DL) component carrier resource prediction enhanced type.

[0230] Step B8: The gNB sets the component carrier payload size identification byte of the component carrier mapping relationship prediction mapping indication subfield to the UE downlink (DL) payload size.

[0231] Step B9: The gNB sets the component carrier interference type and interference strength identification bytes of the component carrier mapping relationship prediction mapping indication subfield to the predicted interference type and interference strength value at the macro cell location where the UE is located.

[0232] Step B10: The gNB sets the component carrier adjustment step and precision selection identification bytes of the component carrier mapping relationship prediction mapping indication subfield to the values ​​preset by the gNB.

[0233] In this embodiment, if the gNB determines that the number of its unallocated carrier resources is large, the gNB will automatically adjust the component carrier adjustment step to a larger value, and at the same time, set the component carrier adjustment accuracy to a larger redundancy, so as to significantly reduce the component carrier resource allocation time while reducing the difficulty of the component carrier resource allocation algorithm.

[0234] Step B11: The gNB pre-allocates UE downlink (DL) component carrier resources based on the component carrier mapping relationship predicted mapping indication subfield.

[0235] Step B12: If the gNB predicts that the mapping indication subfield has not completed the UE downlink (DL) component carrier resource allocation based on the component carrier mapping relationship, the gNB adjusts the component carrier adjustment step and the precision selection identification byte to reallocate the component carrier resources until the UE downlink (DL) component carrier resource allocation is completed.

[0236] Step B13: The gNB allocates UE uplink (UL) component carrier resources based on the component carrier mapping relationship predicted mapping indication subfield.

[0237] Step B14: If the gNB has not completed the UE uplink (UL) component carrier resources, the gNB sequentially adjusts the component carrier interference type and interference intensity identification bytes and the operator band / frequency band identification bytes of the component carrier mapping relationship prediction mapping indication subfield to find the component carrier resources that match the UE uplink (UL) component carrier resources to complete the component carrier allocation.

[0238] In this embodiment, the gNB does not adjust the component carrier adjustment step and precision selection identification byte when allocating UE uplink (UL) component carrier resources to avoid mismatch between UE uplink (UL) and downlink (DL) component carrier resources.

[0239] Step B15: The UE completes carrier aggregation using the uplink (UL) and downlink (DL) carrier resources allocated by the gNB.

[0240] Step B16: The gNB measures the throughput on the carrier aggregation of the UE.

[0241] Step B17: If the throughput value preset by the gNB is not reached, the gNB requests the UE to initiate interference measurement and prediction and returns to step B5.

[0242] The third carrier aggregation asymmetric prediction strategy: an enhanced asymmetric prediction type of uplink (UL) component carrier resources, may include the following steps C1 to C17:

[0243] Step C1: The gNB allocates asymmetric component carrier resources for the UE's uplink (UL) and downlink (DL).

[0244] In this embodiment, when the UE's uplink (UL) service increases significantly, more component carrier resources need to be allocated to the uplink (UE). In order to improve the efficiency of component carrier resource allocation, the gNB allocates asymmetric component carrier resources to the UE's uplink (UL) and downlink (DL).

[0245] Step C2: The gNB dynamically adjusts the component carrier resources of the uplink (UL) and downlink (DL).

[0246] In this embodiment, since the uplink (UL) service demand gNB predicts that the component carrier resource demand will be significantly increased, the gNB predicts that the uplink (UL) component carrier resource allocation will be significantly increased. Exemplarily, it may include: modifying the sub-band duplex mode of the uplink (UL) and / or downlink (DL), and allocating more component carrier resources of the uplink (UL) resources.

[0247] Step C3: The gNB determines that the UE payload classification field is uplink (UL) component carrier resource asymmetric prediction enhanced.

[0248] Step C4: The gNB determines the UE uplink (UL) payload size and modifies the gNB / UE payload size confirmation field.

[0249] Step C5: The gNB sets the interference measurement and prediction fields to the predicted interference type and interference strength value at the macro cell location where the UE is located.

[0250] Step C6: The gNB sets the operator band / frequency band identification byte that constitutes the carrier mapping relationship prediction mapping indication subfield to the current gNB's own identification.

[0251] Step C7: gNB sets the component carrier payload type identification byte of the component carrier mapping relationship prediction mapping indication subfield to the uplink (UL) component carrier resource asymmetric prediction enhanced type.

[0252] Step C8: gNB sets the component carrier payload size identification byte of the component carrier mapping relationship prediction mapping indication subfield to the UE uplink (UL) payload size.

[0253] Step C9: The gNB sets the component carrier interference type and interference strength identification bytes of the component carrier mapping relationship prediction mapping indication subfield to the predicted interference type and interference strength value at the macro cell location where the UE is located.

[0254] Step C10: The gNB sets the component carrier adjustment step and precision selection identification bytes of the component carrier mapping relationship prediction mapping indication subfield to the values ​​preset by the gNB.

[0255] In this embodiment, the uplink (UL) and downlink (DL) use different component carrier adjustment steps and precisions. The uplink (UL) uses a smaller component carrier adjustment step to improve the efficiency of gNB's allocation of uplink (UL) component carrier resources. At the same time, a higher component carrier adjustment precision is used, that is, the gNB accurately allocates the UE's uplink (UL) component carrier resources to further improve the efficiency of gNB's allocation of uplink (UL) component carrier resources. The downlink (DL) uses a larger component carrier adjustment step to minimize the total delay of gNB's uplink (UL) and downlink (DL) component carrier allocation as much as possible. At the same time, a low component carrier adjustment precision is used to further reduce the total delay of gNB's uplink (UL) and downlink (DL) component carrier allocation.

[0256] Step C11: The gNB pre-allocates UE downlink (DL) component carrier resources according to the component carrier mapping relationship predicted mapping indication subfield.

[0257] Step C12: If the gNB predicts that the mapping indication subfield has not completed the UE downlink (DL) component carrier resource allocation based on the component carrier mapping relationship, the gNB will first adjust the duplex mode on the component carrier resources that have been allocated for the uplink (UL) and / or downlink (DL), and complete the downlink (DL) component carrier allocation by means of time domain and / or frequency domain and / or code domain multiplexing; if the downlink (DL) component carrier requirements are still not met, the gNB adjusts the component carrier adjustment step and the precision selection identification byte to reallocate the component carrier resources until the UE downlink (DL) component carrier resource allocation is completed.

[0258] It should be noted that the method in step C12 may result in mismatch between uplink (UL) and downlink (DL) component carrier resources after allocation.

[0259] Step C13: The gNB predicts the mapping indication subfield according to the component carrier mapping relationship and allocates UE uplink (UL) component carrier resources.

[0260] Step C14: If the gNB has not completed the UE uplink (UL) component carrier resources, the gNB sequentially adjusts the component carrier interference type and interference intensity identification bytes and the operator band / frequency band identification bytes of the component carrier mapping relationship prediction mapping indication subfield to find the component carrier resources that match the UE uplink (UL) component carrier resources to complete the component carrier allocation.

[0261] In this embodiment, the gNB does not adjust the component carrier adjustment step and precision selection identification byte when allocating UE uplink (UL) component carrier resources to avoid mismatch between UE uplink (UL) and downlink (DL) component carrier resources.

[0262] Step C15: The UE uses the uplink (UL) and downlink (DL) carrier resources allocated by the gNB to complete carrier aggregation.

[0263] Step C16: The gNB measures the throughput on the carrier aggregation of the UE.

[0264] Step C17: If the throughput value preset by the gNB is not reached, the gNB requests the UE to initiate interference measurement and prediction and returns to step C5.

[0265] The fourth carrier aggregation asymmetric prediction strategy: downlink (DL) component carrier resource asymmetric prediction enhanced type may include the following steps D1 to D17:

[0266] Step D1: The gNB allocates asymmetric component carrier resources for the UE’s uplink (UL) and downlink (DL).

[0267] In this embodiment, when the UE's downlink (DL) traffic increases significantly, more component carrier resources need to be allocated to the uplink (UE). In order to improve the efficiency of component carrier resource allocation, the gNB allocates asymmetric component carrier resources to the UE's uplink (UL) and downlink (DL).

[0268] Step D2: The gNB dynamically adjusts the component carrier resources of the uplink (UL) and downlink (DL).

[0269] In this embodiment, since the gNB predicts that the downlink (DL) service demand will significantly increase the component carrier resource demand, the gNB predicts that the uplink (UL) component carrier resource allocation will be significantly increased. Exemplarily, it may include: modifying the sub-band duplex mode of the uplink (UL) and / or downlink (DL), and allocating more component carrier resources of the downlink (DL) resources.

[0270] Step D3: The gNB determines that the UE payload classification field is downlink (DL) component carrier resource asymmetric prediction enhanced.

[0271] Step D4: The gNB determines the UE downlink (DL) payload size and modifies the gNB / UE payload size confirmation field.

[0272] Step D5: The gNB sets the interference measurement and prediction fields to the predicted interference type and interference strength value at the macro cell location where the UE is located.

[0273] Step D6: The gNB sets the operator band / frequency band identification byte that constitutes the carrier mapping relationship prediction mapping indication subfield to the current gNB's own identification.

[0274] Step D7: The gNB sets the component carrier payload type identification byte of the component carrier mapping relationship prediction mapping indication subfield to the uplink (UL) component carrier resource asymmetric prediction enhanced type.

[0275] Step D8: The gNB sets the component carrier payload size identification byte of the component carrier mapping relationship prediction mapping indication subfield to the UE uplink (UL) payload size.

[0276] Step D9: The gNB sets the component carrier interference type and interference strength identification bytes of the component carrier mapping relationship prediction mapping indication subfield to the predicted interference type and interference strength value at the macro cell location where the UE is located.

[0277] Step D10: The gNB sets the component carrier adjustment step and precision selection identification bytes of the component carrier mapping relationship prediction mapping indication subfield to the values ​​preset by the gNB.

[0278] In this embodiment, different component carrier adjustment steps and precisions are used for the uplink (UL) and downlink (DL). A smaller component carrier adjustment step is used for the uplink (UL) to improve the efficiency of gNB in ​​allocating downlink (DL) component carrier resources. At the same time, a higher component carrier adjustment precision is used, that is, the gNB accurately allocates the downlink (DL) component carrier resources of the UE to further improve the efficiency of gNB in ​​allocating downlink (DL) component carrier resources. A larger component carrier adjustment step is used for the downlink (DL) to minimize the total delay of gNB uplink (UL) and downlink (DL) component carrier allocation as much as possible. At the same time, a low component carrier adjustment precision is used to further reduce the total delay of gNB uplink (UL) and downlink (DL) component carrier allocation.

[0279] Step D11: The gNB pre-allocates UE downlink (DL) component carrier resources based on the component carrier mapping relationship predicted mapping indication subfield.

[0280] Step D12: If the gNB predicts that the mapping indication subfield has not completed the UE uplink (UL) component carrier resource allocation based on the component carrier mapping relationship, the gNB will first adjust the duplex mode on the component carrier resources that have been allocated for the uplink (UL) and / or downlink (DL), and complete the downlink (DL) component carrier allocation by means of time domain and / or frequency domain and / or code domain multiplexing; if the uplink (UL) component carrier requirements are still not met, the gNB adjusts the component carrier adjustment step and the precision selection identification byte to reallocate the component carrier resources until the UE uplink (UL) component carrier resource allocation is completed.

[0281] It should be noted that the method in step D12 may result in mismatch between uplink (UL) and downlink (DL) component carrier resources after allocation.

[0282] Step D13: The gNB predicts the mapping indication subfield and allocates UE downlink (DL) component carrier resources according to the component carrier mapping relationship.

[0283] Step D14: If the gNB has not completed the UE downlink (DL) component carrier resources, the gNB sequentially adjusts the component carrier interference type and interference intensity identification bytes and the operator band / frequency band identification bytes of the component carrier mapping relationship prediction mapping indication subfield to find the component carrier resources that match the UE downlink (DL) component carrier resources to complete the component carrier allocation.

[0284] In this embodiment, the gNB does not adjust the component carrier adjustment step and precision selection identification byte when allocating UE downlink (DL) component carrier resources to avoid mismatch between UE uplink (UL) and downlink (DL) component carrier resources.

[0285] Step D15: The UE uses the uplink (UL) and downlink (DL) carrier resources allocated by the gNB to complete carrier aggregation.

[0286] Step D16: The gNB measures the throughput on the carrier aggregation of the UE.

[0287] Step D17: If the throughput value preset by the gNB is not reached, the gNB requests the UE to initiate interference measurement and prediction and returns to step D5.

[0288] The fifth carrier aggregation asymmetric prediction strategy: interference prediction composition carrier allocation type, may include the following steps E1 to E17:

[0289] Step E1: The interference type and / or interference intensity of the uplink (UL) and / or downlink (DL) of the UE changes.

[0290] In this embodiment, when the interference type and / or interference intensity of the UE's uplink (UL) and / or downlink (DL) changes, it is necessary to configure the component carrier mapping relationship for the uplink (UL) and / or downlink (DL) and / or reallocate the component carrier resources to control the UE's main interference type and / or interference intensity.

[0291] Step E2: gNB first selects and configures the component carrier mapping relationship, specifies the component carrier mapping relationship on the component carrier used by the UE, and reduces the uplink (UL) and / or downlink (DL) interference; secondly, gNB reallocates the component carrier resources, gNB selects the interference type and / or interference intensity of the component carrier whose interference intensity of the uplink (UL) and / or downlink (DL) component carrier resources used by the UE exceeds a preset threshold, gNB selects other interference types and / or component carriers with low interference intensity on the same interference type on the unused component carrier resources to replace the component carrier used by the UE, and re-specifies the component carrier mapping relationship prediction. In this way, the change of UE interference type and / or interference intensity can be controlled.

[0292] Step E3: The gNB dynamically adjusts the interference type and / or interference intensity prediction of all uplink (UL) and / or downlink (DL) component carrier resources, thereby applying the predicted interference when the gNB reallocates component carrier resources.

[0293] Step E4: The gNB determines that the UE payload classification field is interference prediction component carrier allocation type.

[0294] Step E5: The gNB sets the interference measurement and prediction field to the predicted interference type and / or interference intensity value of the component carrier resources used at the macro cell location where the UE is located, and the predicted interference type and / or interference intensity value of the component carrier that exceeds a preset threshold.

[0295] Step E6: The gNB determines the payload size for which the UE interference type and / or interference strength determined by the interference measurement and prediction field exceeds a preset threshold, and modifies the gNB / UE payload size confirmation field.

[0296] Step E7: The gNB sets the operator band / frequency band identification byte that constitutes the carrier mapping relationship prediction mapping indication subfield to the current gNB's own identification.

[0297] Step E8: gNB sets the component carrier payload type identification byte of the component carrier mapping relationship prediction mapping indication subfield to the interference prediction component carrier allocation type.

[0298] Step E9: The gNB sets the component carrier payload size identification byte of the component carrier mapping relationship prediction mapping indication subfield to the value specified by the gNB / UE payload size confirmation field.

[0299] The subfield in this embodiment only identifies the payload size of the component carrier whose interference type and / or interference intensity exceeds the threshold pre-set by the gNB.

[0300] Step E10: gNB sets the component carrier interference type and interference strength identification byte of the component carrier mapping relationship prediction mapping indication subfield to the value set in the interference measurement and prediction field.

[0301] The subfield in this embodiment only identifies the interference type and / or interference intensity of the component carrier whose interference type and / or interference intensity exceeds the threshold preset by the gNB.

[0302] Step E11: gNB sets the component carrier adjustment step and precision selection identification byte of the component carrier mapping relationship prediction mapping indication subfield to a smaller value of the component carrier adjustment step.

[0303] In this embodiment, the method of step E11 can accurately match the component carriers of the UE uplink (UL) and / or downlink (DL) that exceed the interference type and / or interference intensity threshold, effectively control the component carrier interference, and the component carrier adjustment step is set to a low adjustment accuracy, that is, there is redundancy, so as to control the difficulty of component carrier mapping.

[0304] Step E12: The gNB pre-allocates UE downlink (DL) component carrier resources based on the component carrier mapping relationship predicted mapping indication subfield.

[0305] Step E13: If the gNB predicts that the mapping indication subfield has not completed the UE uplink (UL) component carrier resource allocation based on the component carrier mapping relationship, the gNB will first adjust the duplex mode on the component carrier resources that have been allocated for the uplink (UL) and / or downlink (DL), and complete the downlink (DL) component carrier allocation by means of time domain and / or frequency domain and / or code domain multiplexing; if the uplink (UL) component carrier requirements are still not met, the gNB adjusts the component carrier adjustment step and the precision selection identification byte to reallocate the component carrier resources until the UE uplink (UL) component carrier resource allocation is completed.

[0306] It should be noted that the method in step E13 of this embodiment may result in mismatch between uplink (UL) and downlink (DL) component carrier resources after allocation.

[0307] Step E14: The UE completes carrier aggregation using the uplink (UL) and downlink (DL) carrier resources allocated by the gNB.

[0308] Step E15: The gNB measures the throughput on the carrier aggregation of the UE.

[0309] Step E16: If the throughput value preset by the gNB is not reached, the gNB requests the UE to initiate interference measurement and prediction and returns to step E3.

[0310] The sixth carrier aggregation asymmetric prediction strategy: component carrier resource measurement prediction allocation type, belongs to the standard process, alternative type. It is mainly used by the gNB to measure the interference type and / or interference intensity of all component carriers, usually only completed once when the gNB measures and predicts all component carriers on the macro cell.
