Description

Technical Field

[0001] The present disclosure relates to the field of communications, and in particular to a resource configuration method and device, a base station, a communication system, and a storage medium. Background Art

[0002] The energy consumption of a single base station in a 5G network can be more than three times that of a single base station in an LTE (Long Term Evolution) network. Since the spectrum of the 5G network is higher and the density is greater, the total energy consumption of the 5G network is close to four times that of the LTE network, and the energy consumption cost accounts for nearly half of the total network operating cost.

[0003] By flexibly shutting down antenna ports and adjusting antenna transmit power, the network energy consumption of base station signals can be reduced as much as possible. Currently, a port number and a power offset are configured for each CSI (Channel State Information)-RS (Reference Signal) resource. In order to improve the configuration efficiency of CSI-RS resources, multiple CSI-RS resources can be configured simultaneously. Summary of the invention

[0004] The inventors noticed that in the scenario where multiple CSI-RS resources are configured simultaneously, since multiple different port resources need to be configured, according to the existing standards, the corresponding CDM (Code Division Multiplexing) type, timing frequency domain position and other information need to be configured, that is, more parameters need to be configured; at the same time, in the CSI reporting configuration, since multiple CSI-RS need to be reported, multiple reporting information also needs to be configured at the same time, thereby increasing the network burden. For example, simultaneously measuring the CSI under N antenna ports and the CSI-RS under M different transmit powers will make the overall complexity and network signaling overhead N*M times the original.

[0005] Accordingly, the present disclosure provides a resource configuration method, which can effectively reduce the network burden and reduce the measurement complexity while completing multiple CSI measurements through CSI-RS resource configuration and CSI reporting configuration.

[0035] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] Unless specifically stated otherwise, the relative arrangement of components and steps, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0037] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0039] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0040] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0041] Figure 1The following is a flow chart of a resource configuration method according to an embodiment of the present disclosure. In some embodiments, the following resource configuration method is executed by a resource configuration device.

[0042] In step 101, resource configuration (ResourceConfiguration) is performed on each of the multiple CSI-RS resources to obtain a resource configuration result, wherein at least one of the total number of ports and the total number of power control offset values ​​of each CSI-RS resource is greater than 1.

[0043] It should be noted that each of the multiple CSI-RS resources has the same number of ports (Number of ports).

[0044] In some embodiments, the process of configuring each CSI-RS resource in the plurality of CSI-RS resources includes: Figure 2 The process shown.

[0045] In step 201, it is determined whether to configure a preset number of ports for the i-th CSI-RS resource among the multiple CSI-RS resources, where 1≤i≤N, and N is the total number of the multiple CSI-RS resources.

[0046] If a preset number of ports is configured for the i-th CSI-RS resource, step 202 is executed; if a preset number of ports is configured for the i-th CSI-RS resource, step 203 is executed.

[0047] In step 202, a preset number of ports is configured for the i-th CSI-RS resource.

[0048] In some embodiments, a preset plurality of port numbers are written into the port number list of the i-th CSI-RS resource, or a maximum value among the preset plurality of port numbers is written into the port number list of the i-th CSI-RS resource, and a multipattern flag (multipatternflag) of the i-th CSI-RS resource is set to a preset value. For example, the preset value is 1.

[0049] For example, the number of ports configured for the i-th CSI-RS resource is 8, 12, and 16, and the port number list of the i-th CSI-RS resource includes {8, 12, and 16}.

[0050] For another example, if the maximum number of ports configured for the i-th CSI-RS resource is 16, the port number list of the i-th CSI-RS resource only includes {16}, and the multi-pattern flag = 1. This means that the number of ports configured for the i-th CSI-RS resource is 1, 2, 4, 8, 12, 16.

[0051] In step 203, a preset port number of 1 is configured for the i-th CSI-RS resource.

[0052] In some embodiments, a preset port number of 1 is written into the port number list of the i-th CSI-RS resource.

[0053] It should be noted that, when a preset port number of 1 is configured for the i-th CSI-RS resource, the port number list of the i-th CSI-RS resource includes only 1 port number, and the multi-pattern flag = 0 or the multi-pattern flag is not configured.

[0054] In some embodiments, Figure 2 Based on this, the process of configuring each CSI-RS resource in the multiple CSI-RS resources also includes the following steps: Figure 3 The process shown.

[0055] In step 301, it is determined whether a plurality of preset power control offset values ​​(powerControlOffset) are configured for the i-th CSI-RS resource.

[0056] It should be noted that the power control offset value is an offset relative to the transmit power of PDSCH (Physical Downlink Shared Channel).

[0057] If a plurality of preset power control offset values ​​are configured for the i-th CSI-RS resource, step 302 is executed; if a preset power control offset value is configured for the i-th CSI-RS resource, step 303 is executed.

[0058] In step 302, a plurality of preset power control offset values ​​are configured for the i-th CSI-RS resource.

[0059] In some embodiments, a preset plurality of power control offset values ​​are written into the power list of the i-th CSI-RS resource, or a preset plurality of power control offset values ​​are configured for the i-th CSI-RS resource with a power control offset value upper limit (powerControlOffsetUpperLimit) and a power control offset value lower limit (powerControlOffsetLowerLimit).

[0060] For example, the power control offset values ​​configured for the i-th CSI-RS resource are -3, -2, -1, 0, 1, 2, 3, then the power control offset value list for the i-th CSI-RS resource includes {-3, -2, -1, 0, 1, 2, 3}.

[0061] For another example, the power control offset value configured for the i-th CSI-RS resource is -3, -2, -1, 0, 1, 2, 3, where the maximum value is 3 and the minimum value is -3. Then the lower limit of the power control offset value configured for the i-th CSI-RS resource is -3, and the upper limit of the power control offset value for the i-th CSI-RS resource is 3, so that the obtained power control offset value range is [-3, 3].

[0062] In step 303, a preset power control offset value is configured for the i-th CSI-RS resource.

[0063] It should be noted that, when a preset power control offset value is configured for the i-th CSI-RS resource, the power control offset value list of the i-th CSI-RS resource only includes one power control offset value.

[0064] In step 102, CSI reporting configuration (CSI reportConfiguration) is performed on multiple CSI-RS resources according to the resource configuration result to obtain a CSI reporting configuration result.

[0065] In some embodiments, the process of performing CSI reporting configuration on multiple CSI-RS resources according to the resource configuration result is as follows: Figure 4 shown.

[0066] In step 401, it is determined whether each CSI-RS resource is configured with multiple port numbers.

[0067] In some embodiments, it is determined whether the port number list of each CSI-RS resource is configured with multiple port numbers. If the port number list of each CSI-RS resource includes multiple port numbers, it is determined that each CSI-RS resource is configured with multiple port numbers.

[0068] In some embodiments, if the port number list of each CSI-RS resource includes only one port number, it is further determined whether the multi-pattern flag of each CSI-RS resource is a preset value. If the multi-pattern flag of each CSI-RS resource is a preset value, it is determined that each CSI-RS resource is configured with multiple port numbers, and one port number in the port number list is used as the maximum port number.

[0069] For example, the default value is 1.

[0070] If each CSI-RS resource is configured with multiple port numbers, execute step 402 ; if each CSI-RS resource is configured with one port number, execute step 405 .

[0071] In step 402, at least part of the multiple port numbers are used as multiple target port numbers.

[0072] It should be noted here that, when the port number list of each CSI-RS resource includes multiple port numbers, the multiple port numbers are used as multiple target port numbers.

[0073] In the case where the maximum port number is included in the port number list of each CSI-RS resource, a predetermined number of port numbers are selected as a plurality of target port numbers from among a plurality of port numbers determined by the maximum port number.

[0074] In step 403, a plurality of first sub-configuration information corresponding to a plurality of target port numbers are generated according to a plurality of CSI-RS resources, wherein each first sub-configuration information includes a corresponding target port number.

[0075] In some embodiments, each first sub-configuration information further includes a resource identifier of each CSI-RS resource.

[0076] In step 404, one or more transmit power offset values ​​are configured for each first sub-configuration information.

[0077] For example, a resource set includes two CSI-RS resources, namely CSI-RS#1 and CSI-RS#2. The number of ports configured for CSI-RS#1 is {8, 12, 16}, and the power control offset value range is [-2, 0] dB. The number of ports configured for CSI-RS#2 is {8, 12, 16}, and the power control offset value range is [-1, 1] dB.

[0078] The following three sub-configuration information are generated in the CSI reporting configuration.

[0079] ·sub#1(#ports=8):{CSI-RS#1,#2}

[0080] ·sub#2(#ports=12):{CSI-RS#1,#2}

[0081] ·sub#3(#ports=16):{CSI-RS#1,#2}

[0082] It should be noted that, since each sub-configuration information includes the same resource identifier of the CSI-RS resource, each sub-configuration information may not include the resource identifier of the CSI-RS resource.

[0083] Next, in these three sub-configuration information, the transmit power offset value configured for the first sub-configuration information is {-2}, the transmit power offset value configured for the second sub-configuration information is {-2, 0}, and the transmit power offset value configured for the third sub-configuration information is {1}. Then the configured transmit power offset values ​​{-2}, {-2, 0}, and {1} are sent to the user terminal. Based on the above three sub-configuration information and the transmit power offset value configured for each sub-configuration information, the user terminal determines the CSI-RS resources to be detected as follows:

[0084] CSI-RS#1, port 8, transmit power offset value is -2dB

[0085] CSI-RS#1, port 12, transmit power offset value is -2dB

[0086] CSI-RS#1, port 12, transmit power offset value is 0dB

[0087] CSI-RS#2, port 12, transmit power offset value is 0dB

[0088] CSI-RS#2, port 16, transmit power offset value is 1dB

[0089] For another example, a resource set includes two CSI-RS resources, namely CSI-RS#1 and CSI-RS#2. The maximum number of ports configured for CSI-RS#1 is 16, and the power control offset value range is [-2, 0] dB. The maximum number of ports configured for CSI-RS#2 is 16, and the power control offset value range is [-1, 1] dB.

[0090] Among the multiple port numbers determined by the maximum port number being 16, three port numbers are selected, namely {8, 12, 16}, and then the following three sub-configuration information are generated in the CSI reporting configuration.

[0091] ·sub#1(#ports=8):{CSI-RS#1,#2}

[0092] ·sub#2(#ports=12):{CSI-RS#1,#2}

[0093] ·sub#3(#ports=16):{CSI-RS#1,#2}

[0094] It should be noted that, since each sub-configuration information includes the same resource identifier of the CSI-RS resource, each sub-configuration information may not include the resource identifier of the CSI-RS resource.

[0095] Next, in these three sub-configuration information, the transmit power offset value configured for the first sub-configuration information is {-2}, the transmit power offset value configured for the second sub-configuration information is {-2, 0}, and the transmit power offset value configured for the third sub-configuration information is {1}. Then the configured transmit power offset values ​​{-2}, {-2, 0}, and {1} are sent to the user terminal. Based on the above three sub-configuration information and the transmit power offset value configured for each sub-configuration information, the user terminal determines the CSI-RS resources to be detected as follows:

[0096] CSI-RS#1, port 8, transmit power offset value is -2dB

[0097] CSI-RS#1, port 12, transmit power offset value is -2dB

[0098] CSI-RS#1, port 12, transmit power offset value is 0dB

[0099] CSI-RS#2, port 12, transmit power offset value is 0dB

[0100] CSI-RS#2, port 16, transmit power offset value is 1dB

[0101] In step 405, it is determined whether each CSI-RS resource is configured with multiple power control offset values.

[0102] If each CSI-RS resource is configured with multiple power control offset values, step 406 or step 408 may be performed according to the preset configuration. If each CSI-RS resource includes one power control offset value, step 409 is performed.

[0103] In step 406, multiple second sub-configuration information is generated according to the multiple CSI-RS resources, wherein each second sub-configuration information includes a resource identifier of at least one CSI-RS resource among the multiple CSI-RS resources, and a power offset value corresponding to the resource identifier of the at least one CSI-RS resource, and there is no intersection between any two second sub-configuration information.

[0104] In step 407, one or more transmit power offset values ​​are configured for each second sub-configuration information.

[0105] For example, a resource set includes two CSI-RS resources, namely CSI-RS#1 and CSI-RS#2. The number of ports configured for CSI-RS#1 and CSI-RS#2 is 16 (the port patterns are different), and the power control offset value range of CSI-RS#1 is [-3, 3] dB. The power control offset value range of CSI-RS#2 is [-2, 5] dB.

[0106] The following three sub-configuration information are generated in the CSI reporting configuration.

[0107] ·sub#1(power-offset=-3):{CSI-RS#1}

[0108] ·sub#2(power-offset=-2,-1,1,2,3):{CSI-RS#1,#2}

[0109] ·sub#3(power-offset=4,5):{CSI-RS#2}

[0110] Next, in these three sub-configuration information, the transmit power offset value configured for the first sub-configuration information is {-3}, the transmit power offset value configured for the second sub-configuration information is {2}, and the transmit power offset value configured for the third sub-configuration information is {5}. Then the configured transmit power offset values ​​{-3}, {2}, and {5} are sent to the user terminal. Based on the above three sub-configuration information and the transmit power offset value configured for each sub-configuration information, the user terminal determines the CSI-RS resources to be detected as follows:

[0111] CSI-RS#1, port 16, transmit power offset value is -3dB

[0112] CSI-RS#1, port 16, transmit power offset value is 2dB

[0113] CSI-RS#2, port 16, transmit power offset value is 2dB

[0114] CSI-RS#2, port 16, transmit power offset value is 5dB

[0115] In step 408, one or more transmit power offset values ​​are configured for each CSI-RS resource.

[0116] For example, a resource set includes two CSI-RS resources, namely CSI-RS#1 and CSI-RS#2. The number of ports configured for CSI-RS#1 and CSI-RS#2 is 16 (the port patterns are different), and the power control offset value range of CSI-RS#1 is [-3, 3] dB. The power control offset value range of CSI-RS#2 is [-2, 5] dB.

[0117] Next, the transmit power offset values ​​configured for CSI-RS#1 and CSI-RS#2 are {-3}, {2}, {5}. The configured transmit power offset values ​​{-3}, {2}, {5} are then sent to the user terminal. The user terminal determines the CSI-RS resources to be detected based on the transmit power offset values ​​{-3}, {2}, {5} configured for CSI-RS#1 and CSI-RS#2 as follows:

[0118] CSI-RS#1, port 16, transmit power offset value is -3dB

[0119] CSI-RS#1, port 16, transmit power offset value is 2dB

[0120] CSI-RS#2, port 16, transmit power offset value is 2dB

[0121] CSI-RS#2, port 16, transmit power offset value is 5dB

[0122] In step 409, processing is performed according to the existing preset standard process.

[0123] Since the existing standard process is well known to those skilled in the art, it will not be described in detail here.

[0124] return Figure 1 In step 103, the CSI reporting configuration result is sent to the user terminal.

[0125] In the resource configuration method provided in the above embodiment, through CSI-RS resource configuration, at least one of the total number of ports and the total number of power control offset values ​​of each CSI-RS resource is greater than 1, and then CSI reporting configuration is performed based on the CSI-RS resource configuration. In this way, while completing multiple CSI measurements, the network burden and measurement complexity can be effectively reduced.

[0126] In addition, the present disclosure obtains a more flexible resource configuration method with less overhead, thereby having higher flexibility and smaller granularity, effectively improving resource configuration efficiency.

[0127] Figure 5 FIG. 1 is a schematic diagram of the structure of a resource configuration device according to an embodiment of the present disclosure. Figure 5 As shown, the resource configuration device includes a first processing module 51 and a second processing module 52 .

[0128] The first processing module 51 is configured to perform resource configuration on each CSI-RS resource among multiple CSI-RS resources to obtain a resource configuration result, wherein at least one of the total number of ports and the total number of power control offset values ​​of each CSI-RS resource is greater than 1.

[0129] It should be noted that each CSI-RS resource has the same number of ports.

[0130] In some embodiments, the first processing module 51 is configured to determine whether to configure a preset multiple number of ports for the i-th CSI-RS resource among the multiple CSI-RS resources, 1≤i≤N, and N is the total number of the multiple CSI-RS resources. If the preset multiple number of ports is configured for the i-th CSI-RS resource, the first processing module 51 writes the preset multiple number of ports in the port number list of the i-th CSI-RS resource, or writes the maximum value of the preset multiple number of ports in the port number list of the i-th CSI-RS resource, and sets the multi-pattern flag of the i-th CSI-RS resource to a preset value.

[0131] For example, the default value is 1.

[0132] In some embodiments, the first processing module 51 is configured to determine whether to configure a plurality of preset power control offset values ​​for the i-th CSI-RS resource. If a plurality of preset power control offset values ​​are configured for the i-th CSI-RS resource, the first processing module 51 writes the plurality of preset power control offset values ​​into the power list of the i-th CSI-RS resource, or configures the power control offset value upper limit and the power control offset value lower limit of the plurality of preset power control offset values ​​for the i-th CSI-RS resource.

[0133] The second processing module 52 is configured to perform CSI reporting configuration on multiple CSI-RS resources according to the resource configuration result to obtain a CSI reporting configuration result, and send the CSI reporting configuration result to the user terminal.

[0134] In some embodiments, the second processing module 52 is configured to determine whether each CSI-RS resource is configured with multiple port numbers. If each CSI-RS resource is configured with multiple port numbers, at least part of the multiple port numbers are used as multiple target port numbers, and multiple first sub-configuration information corresponding to the multiple target port numbers are generated according to the multiple CSI-RS resources, wherein each first sub-configuration information includes the corresponding target port number, and one or more transmission power offset values ​​are configured for each first sub-configuration information.

[0135] In some embodiments, each first sub-configuration information further includes a resource identifier of each CSI-RS resource in the plurality of CSI-RS resources.

[0136] In some embodiments, the second processing module 52 is configured to determine whether the port number list of each CSI-RS resource includes multiple port numbers. If the port number list of each CSI-RS resource includes multiple port numbers, it is determined that each CSI-RS resource is configured with multiple port numbers.
