Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to an interference processing method, device, base station and terminal. Background Art

[0002] In order to achieve rapid construction of 5G networks and reduce the scale of network investment, 5G commercial networks usually use medium and low frequency bands for continuous coverage. Therefore, they have the same frequency band as 4G commercial networks, causing mutual co-frequency interference. In a typical network frequency deployment, the 5G cell bandwidth is 100MHz, and there are multiple 4G cells with a bandwidth of 20MHz. 5G cells and 4G may have overlapping networks of 20MHz and 40MHz. The test results show that the 5G cell rate drops by 20-40% on average.

[0003] In the existing technology, based on the fact that 5G can support uplink / downlink frequency selection scheduling, the channel quality under different bandwidths is configured to select the frequency resources with the best channel for transmission. However, this method requires the configuration of multiple groups of CSI-RS resources, resulting in the consumption of system resources (such as when there are many users in the cell) and increased terminal power consumption.

[0122] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0123] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0124] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0125] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0126] like Figure 1 As shown, an interference processing method according to an embodiment of the present invention is applied to a base station, including:

[0127] Step 101: Select a first target resource corresponding to a first terminal according to first measurement result information reported by the first terminal; wherein the first terminal is a terminal supporting narrowband measurement; and the first measurement result information is a result of channel quality measurement performed by the first terminal on all candidate resources.

[0128] Here, the first terminal supporting narrowband measurement will report its first measurement result information, that is, the results of channel quality measurement on all candidate resources. In this way, in this step, the base station can select the first target resource corresponding to the first terminal according to the first measurement result information reported by the first terminal to execute the next step.

[0129] Step 102: When the first target resource is a narrowband resource, configure the first terminal to perform data transmission and channel quality measurement only on the first target resource within a preset time.

[0130] After selecting the first target resource in step 101, the base station will learn that there is interference in the transmission based on the fact that the first target resource is a narrowband resource. In this step, when the first target resource is a narrowband resource, the first terminal is configured to perform data transmission and channel quality measurement only on the first target resource within a preset time.

[0131] In this way, through steps 101 and 102, the base station can select a first target resource for the first terminal based on the result of the channel quality measurement of the first terminal on all the alternative resources; thereafter, when the first target resource is a narrowband resource, the first terminal is configured to perform data transmission and channel quality measurement only on the first target resource within a preset time. In this way, the first terminal can avoid the waste of resources for performing data transmission and channel quality measurement on broadband resources within the preset time, thereby reducing terminal power consumption.

[0132] The candidate resources include broadband resources and narrowband resources. Figure 2As shown, the bandwidth of 5G base station communication is 100MHz, including resource A (60MHz), resource B (20MHz) and resource C (20MHz). Correspondingly, the broadband resources for communication between terminal A and the 5G base station are resource A, resource B and resource C, and the narrowband resources are resource A, resource B, resource C, and the combination of resource A, resource B and resource C. Therefore, the first measurement result information of terminal A will include the results of channel quality measurement on broadband resources (A+B+C) and narrowband resources (A, B, C, A+B, A+C, B+C). At this time, the bandwidth of the first 4G base station communication is 40MHz, including resource B and resource C, and the bandwidth of the second 4G base station communication is 20MHz, including resource C. Therefore, there may be 20MHz and 40MHz overlapping networking between 5G and 4G. The 5G base station using the method of the embodiment of the present invention selects the first target resource corresponding to terminal A according to the first measurement result information, and the first target resource is resource A. Since the first target resource is a narrowband resource, terminal A can be configured to perform data transmission and channel quality measurement only on resource A within a preset time. In this way, terminal A can avoid the waste of resources for performing data transmission and channel quality measurement on broadband resources within the preset time, thereby reducing terminal power consumption.

[0133] Of course, the first terminal reporting the first measurement result information may be implemented based on the configuration of the base station. For example, the first terminal receives transmission configuration information and measurement configuration information from the base station, the transmission configuration information is used to configure the first terminal to perform data transmission on broadband resources, and the measurement configuration information is used to configure the first terminal to perform channel quality measurement on all candidate resources.

[0134] In this embodiment, optionally, step 101 includes:

[0135] Obtaining a transmission rate of each candidate resource according to the first measurement result information;

[0136] A candidate resource with the highest transmission rate among all candidate resources is selected as the first target resource.

[0137] Here, considering the impact of heterogeneous system interference on the transmission rate, the transmission rate of each candidate resource is obtained based on the first measurement result information, and the candidate resource with the largest transmission rate is used as the first target resource. Afterwards, it is further determined whether the first target resource is a narrowband resource.

[0138] It should be known that in this embodiment, the preset time can be set by the state timer T band Thus, when the first target resource is a narrowband resource, the base station activates the state timer. During the state timer, the base station performs data transmission and channel quality measurement configuration only on the selected candidate resource (the first target resource as the narrowband resource).

[0139] Of course, since the interference from the heterogeneous system changes dynamically in the time and frequency domains, in order to better adapt to the occurrence of dynamic changes, optionally, after selecting the first target resource corresponding to the first terminal, the method further includes:

[0140] When the first target resource is a narrowband resource, the first terminal is configured to resume data transmission on the broadband resource and to perform channel quality measurement on the alternative resource after the preset time expires.

[0141] Here, if the first target resource is a narrowband resource, the first terminal will be configured to resume data transmission on the broadband resource and perform channel quality measurement on the alternative resource after the preset time expires, and then make timely adjustments to the dynamic changes of the heterogeneous system interference. Of course, if the preset time is set by the state timer T band It is set that after the timer expires, the data transmission between the first terminal and the base station can be restored on the full bandwidth, and the channel quality measurement on the alternative resources is performed to make adaptive transmission adjustments according to the current interference.

[0142] In this embodiment, optionally, after selecting the first target resource corresponding to the first terminal, the method further includes:

[0143] When the first target resource is a narrowband resource, acquiring a beam direction where the first terminal is located;

[0144] Storing a correspondence between the beam direction of the first terminal, the second measurement result information, and the first target resource;

[0145] The second measurement result information is a result of channel quality measurement performed by the first terminal on broadband resources in the first measurement result information.

[0146] Here, the beam direction of the first terminal is determined by the base station based on the channel detection reference signal SRS of the first terminal. Of course, when the beam direction needs to be obtained, the base station will configure the first terminal to transmit SRS, such as sending SRS configuration information to the first terminal to trigger the first terminal to transmit SRS.

[0147] In this way, in the case where the first target resource is a narrowband resource, the beam direction of the first terminal will be obtained, so that the beam direction, the second measurement result information (that is, the result of the channel quality measurement performed by the first terminal on the broadband resource in the first measurement result information) and the first target resource are stored accordingly, so as to determine the transmission resources of the terminal that does not support narrowband measurement in the same application scenario.

[0148] Thus, in the case of a terminal that does not support narrowband measurement, in this embodiment, Figure 3 As shown, it also includes:

[0149] Step 301, obtaining a beam direction where a second terminal is located and third measurement result information;

[0150] Step 302: query the corresponding second target resource in the stored information according to the beam direction of the second terminal and the third measurement result information;

[0151] Step 303: if the second target resource is found, data transmission is performed on the second target resource;

[0152] Step 304: if the second target resource is not found, data transmission is performed on a preset narrowband resource;

[0153] The second terminal is a terminal that does not support narrowband measurement;

[0154] The third measurement result information is a result of channel quality measurement performed by the second terminal on the broadband resource.

[0155] Here, the stored information is the correspondence between the beam direction, measurement result information, and resources stored by the base station when other terminals supporting narrowband measurement select narrowband resources for transmission, such as the correspondence between the beam direction of the first terminal, the second measurement result information, and the first target resource. In this way, for terminals that do not support narrowband measurement, since it is impossible to directly measure the channel quality on the narrowband resource, according to the above steps 301-304, first obtain the beam direction of the second terminal and the result of the channel quality measurement of the second terminal on the broadband resource, and then query the second target resource in the stored information, and refer to the processing of other terminals supporting narrowband measurement in the same scenario to select the transmission resource.

[0156] For example, the base station has stored information recording the beam direction 1 of terminal A (a terminal supporting narrowband measurement). When transmitting only on narrowband resource A, the broadband measurement result information (i.e., the result of channel quality measurement on broadband resources) is M. For terminal B that does not support narrowband measurement, if the beam direction 1 and broadband measurement result information M are obtained, the application scenario of terminal B can also use transmission only on narrowband resource A.

[0157] Of course, if the used resource is not found in the stored information, data transmission will be performed on the preset narrowband resource. The preset narrowband resource is pre-set, such as narrowband resource A; or the preset narrowband resource is selected by the base station based on the terminal service demand, such as A+B, A+B+C.

[0158] Among them, the beam direction of the second terminal can also be determined by the base station based on the SRS of the second terminal. Of course, when the beam direction needs to be obtained, the base station will configure the second terminal to transmit SRS, such as sending SRS configuration information to the second terminal to trigger the second terminal to transmit SRS.

[0159] It can be seen from the above content that this embodiment also includes:

[0160] Send configuration information;

[0161] The configuration information includes configuration information of a channel sounding reference signal and / or configuration information of a channel quality measurement;

[0162] The channel sounding reference signal is used to determine the beam direction.

[0163] The SRS configuration information is used to configure the terminal to transmit SRS, and the channel quality measurement configuration information is used to configure the terminal to perform channel quality measurement. Of course, the configuration information may also include transmission configuration information, configuring the terminal to perform data transmission on broadband resources or narrowband resources, and so on.

[0164] In addition, in this embodiment, the channel quality measurement result information may include a channel quality indicator CQI, a precoding matrix indicator PMI, a rank indicator RANK, etc., which are not listed one by one here.

[0165] To sum up, the method of the embodiment of the present invention can address the interference caused by heterogeneous systems. For terminals that support frequency selective scheduling, the transmittable frequency can be selected based on the frequency selective scheduling, and the pilot and status timer can be configured for the selected frequency combination. On the one hand, the pilot overhead can be reduced and terminal power consumption can be saved. On the other hand, the interference of heterogeneous systems can be randomized through semi-static resource scheduling. For terminals that do not support frequency selective scheduling, the SRS and broadband measurement information can be measured and compared with the network storage information to determine the optimal scheduling resources and improve the rate.

[0166] like Figure 4 As shown, an interference processing method according to an embodiment of the present invention is applied to a terminal, including:

[0167] Step 401, reporting first measurement result information;

[0168] The first measurement result information is a result of the terminal performing channel quality measurement on all candidate resources.

[0169] Here, the terminal applying the method of the embodiment of the present invention is a terminal supporting narrowband measurement (i.e., the first terminal in the previous embodiment). By reporting the results of channel quality measurement on all candidate resources to the base station, the base station selects the first target resource corresponding to the first terminal based on the first measurement result information, and when the first target resource is a narrowband resource, configures the first terminal to perform data transmission and channel quality measurement only on the first target resource within a preset time. In this way, the first terminal can avoid the waste of resources for data transmission and channel quality measurement on broadband resources within the preset time, thereby reducing terminal power consumption.

[0170] Optionally, after reporting the first measurement result information, the method further includes:

[0171] performing data transmission and channel quality measurement on the first target resource;

[0172] The first target resource is the candidate resource with the highest transmission rate among all candidate resources.

[0173] Here, the first target resource is the first target resource corresponding to the first terminal selected by the base station according to the first measurement result information. It is the candidate resource with the highest transmission rate among all candidate resources. Therefore, the terminal will perform data transmission and channel quality measurement on the first target resource.

[0174] Optionally, it also includes:

[0175] receiving configuration information of a base station;

[0176] The configuration information includes configuration information of a channel sounding reference signal and / or configuration information of a channel quality measurement;

[0177] The channel sounding reference signal is used to determine the beam direction.

[0178] Based on the received configuration information of the base station, the terminal can perform operations such as transmitting SRS and measuring channel quality. Of course, the configuration information can also include transmission configuration information, configuring the terminal to perform data transmission on broadband resources or narrowband resources, and so on.

[0179] In addition, from the implementation method of the previous interference processing method embodiment applied to the base station, it can be seen that the first terminal can also execute: transmit SRS to the base station, and the base station obtains the beam direction of the first terminal, thereby storing the correspondence between the beam direction of the first terminal, the second measurement result information and the first target resource, so as to determine the transmission resources of the terminal that does not support narrowband measurement in the same application scenario.

[0180] It should be noted that the implementation method of the first terminal in the previous embodiment of the interference processing method applied to the base station is applicable to this embodiment and can also achieve the same technical effect.

[0256] The transceiver 910 is used to receive and send data under the control of the processor 900 .

[0257] Among them, Fig. 9 In the embodiment, the bus architecture may include any number of interconnected buses and bridges, specifically linking together various circuits of one or more processors represented by processor 900 and memory represented by memory 920. The bus architecture may also link together various other circuits such as peripherals, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. The bus interface provides an interface. The transceiver 910 may be a plurality of components, i.e., including a transmitter and a receiver, providing a unit for communicating with various other devices on a transmission medium. The processor 900 is responsible for managing the bus architecture and general processing, and the memory 920 may store data used by the processor 900 when performing operations.

[0258] A computer-readable storage medium according to an embodiment of the present invention stores a program or instruction thereon, and when the program or instruction is executed by a processor, the interference processing method applied to the base station or the steps in the interference processing method applied to the terminal can be implemented, and the same technical effect can be achieved.

[0259] It should be further explained that the terminals described in this specification include but are not limited to smart phones, tablet computers, etc., and many of the functional components described are called modules in order to more particularly emphasize the independence of their implementation methods.

[0260] In the embodiment of the present invention, module can be implemented with software so that it can be executed by various types of processors. For example, an executable code module of an identification can include one or more physical or logical blocks of computer instructions, for example, it can be constructed as an object, process or function. Nevertheless, the executable code of the identified module does not need to be physically located together, but can include different instructions stored in different positions, and when these instructions are logically combined together, it constitutes a module and realizes the specified purpose of the module.

[0261] In fact, executable code module can be a single instruction or many instructions, and can even be distributed on a plurality of different code segments, distributed among different programs, and distributed across a plurality of memory devices. Similarly, operating data can be identified in the module, and can be implemented and organized in the data structure of any appropriate type according to any appropriate form. The operating data can be collected as a single data set, or can be distributed in different locations (including on different storage devices), and can only be present on a system or network as an electronic signal at least in part.

[0262] When a module can be implemented by software, considering the level of existing hardware technology, a person skilled in the art can build a corresponding hardware circuit to implement the corresponding function of the module that can be implemented by software without considering the cost. The hardware circuit includes a conventional very large scale integration (VLSI) circuit or gate array and existing semiconductors such as logic chips, transistors, or other discrete components. The module can also be implemented by a programmable hardware device, such as a field programmable gate array, a programmable array logic, a programmable logic device, etc.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
