Description

[0001] This application is a divisional application of a Chinese patent application filed with the State Intellectual Property Office of China on August 11, 2023, with the application number: 202311013582.2 and the invention title "Resource Allocation Method and Apparatus, Base Station, Communication System, and Storage Medium". Technical Field

[0002] The present disclosure relates to the field of communications, and in particular, to a measurement method, user equipment, communication system, and storage medium. Background Art

[0003] The energy consumption of a single base station in a 5G network can reach more than three times that of a single base station in an LTE (Long Term Evolution) network. Moreover, since the spectrum of the 5G network is higher and denser, 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 operation cost.

[0004] By flexibly turning off antenna ports and adjusting antenna transmission power, the network energy consumption of the base station for transmitting 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. To improve the configuration efficiency of CSI-RS resources, multiple CSI-RS resources can be configured simultaneously. Summary of the Invention

[0005] The inventors noticed that in the scenario of simultaneously configuring multiple CSI-RS resources, since multiple different port resources need to be configured, according to existing standards, corresponding CDM (Code Division Multiplexing) types, timing frequency-domain positions, and other information also need to be configured, that is, more parameters need to be configured. At the same time, in the CSI reporting configuration, since multiple CSI-RSs need to be reported, multiple reporting information also needs to be configured simultaneously, thus increasing the network burden. For example, simultaneously measuring CSI at N antenna port numbers and CSI-RS at M different transmission powers will make the overall complexity and network signaling overhead become N*M times the original.

[0006] Accordingly, the present disclosure provides a resource allocation method. Through CSI-RS resource allocation and CSI reporting configuration, while completing multiple CSI measurements, the network burden can be effectively reduced and the measurement complexity can be lowered.

[0033] In some embodiments, the base station selects a predetermined number of port numbers from the multiple port numbers as the multiple target port numbers.

[0054] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some embodiments of the present disclosure, rather than all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present disclosure.

[0055] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present disclosure.

[0056] Meanwhile, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship.

[0057] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification.

[0058] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0059] It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0060] Figure 1 The flowchart shows the 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, including steps 101-103.

[0061] In step 101, resource configuration (ResourceConfiguration) is performed on each CSI-RS resource among a plurality of CSI-RS resources to obtain a resource configuration result, where 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.

[0062] It should be noted that each CSI-RS resource among the plurality of CSI-RS resources has the same number of ports (Numberof ports).

[0063] In some embodiments, the process of performing resource configuration on each CSI-RS resource among the plurality of CSI-RS resources includes the process as Figure 2 shown, including steps 201-203.

[0064] In step 201, it is judged whether to configure a preset number of ports for the i-th CSI-RS resource among the plurality of CSI-RS resources, , where N is the total number of the plurality of CSI-RS resources.

[0065] If the preset number of ports is configured for the i-th CSI-RS resource, step 202 is executed; if a preset 1 port is configured for the i-th CSI-RS resource, step 203 is executed.

[0066] In step 202, configure a preset number of multiple ports for the i-th CSI-RS resource.

[0067] In some embodiments, write the preset number of multiple ports into the port number list of the i-th CSI-RS resource, or write the maximum value among the preset number of multiple ports into the port number list of the i-th CSI-RS resource, and set the multi-pattern flag of the i-th CSI-RS resource to a preset value. For example, the preset value is 1.

[0068] For example, if the ports configured for the i-th CSI-RS resource are 8, 12, and 16, then the port number list of the i-th CSI-RS resource includes {8, 12, 16}.

[0069] For another example, if the maximum number of ports configured for the i-th CSI-RS resource is 16, then the port number list of the i-th CSI-RS resource only includes {16}, and at the same time, the multi-pattern flag = 1. This means that the multiple port numbers configured for the i-th CSI-RS resource are 1, 2, 4, 8, 12, 16.

[0070] In step 203, configure a preset 1 port number for the i-th CSI-RS resource.

[0071] In some embodiments, write the preset 1 port number into the port number list of the i-th CSI-RS resource.

[0072] It should be noted that in the case of configuring a preset 1 port number for the i-th CSI-RS resource, the port number list of the i-th CSI-RS resource only includes 1 port number, and the multi-pattern flag = 0 or the multi-pattern flag is not configured.

[0073] In some embodiments, on the basis of Figure 2 , the process of resource configuration for each CSI-RS resource among multiple CSI-RS resources further includes the process as shown in Figure 3 and includes steps 301-303.

[0074] In step 301, determine whether to configure a preset number of multiple power control offset values for the i-th CSI-RS resource.

[0075] It should be noted that the power control offset value is an offset relative to the transmit power of the PDSCH (Physical Downlink Shared Channel).

[0076] If there are multiple power control offset values preset for the i-th CSI-RS resource configuration, step 302 is executed; if there is 1 power control offset value preset for the i-th CSI-RS resource configuration, step 303 is executed.

[0077] In step 302, multiple power control offset values preset for the i-th CSI-RS resource are configured.

[0078] In some embodiments, multiple preset power control offset values are written into the power list of the i-th CSI-RS resource, or the power control offset upper limit (powerControlOffsetUpperLimit) and the power control offset lower limit (powerControlOffsetLowerLimit) of multiple preset power control offset values are configured for the i-th CSI-RS resource.

[0079] For example, if 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 of the i-th CSI-RS resource includes {-3, -2, -1, 0, 1, 2, 3}.

[0080] For another example, if the power control offset values configured for the i-th CSI-RS resource are -3, -2, -1, 0, 1, 2, 3, where the maximum value is 3 and the minimum value is -3, then the power control offset lower limit of the i-th CSI-RS resource is configured to be -3, and the power control offset upper limit of the i-th CSI-RS resource is 3, so that the obtained power control offset value range is -3, 3.

[0081] In step 303, 1 power control offset value preset for the i-th CSI-RS resource is configured.

[0082] It should be noted that in the case of configuring 1 power control offset value preset for the i-th CSI-RS resource, the power control offset value list of the i-th CSI-RS resource only includes 1 power control offset value.

[0083] In step 102, CSI report configuration (CSI reportConfiguration) is performed on multiple CSI-RS resources according to the resource configuration result to obtain a CSI report configuration result.

[0084] In some embodiments, the process of performing CSI report configuration on multiple CSI-RS resources according to the resource configuration result is as Figure 4 shown, including steps 401-409.

[0085] In step 401, it is judged whether each CSI-RS resource is configured with multiple port numbers.

[0086] In some embodiments, it is determined whether multiple port numbers are configured in the port number list of each CSI-RS resource. If multiple port numbers are included in the port number list of each CSI-RS resource, it is determined that each CSI-RS resource is configured with multiple port numbers.

[0087] In some embodiments, if only 1 port number is included in the port number list of each CSI-RS resource, 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 the preset value, it is determined that each CSI-RS resource is configured with multiple port numbers, and the 1 port number in the port number list is used as the maximum port number.

[0088] For example, the preset value is 1.

[0089] If each CSI-RS resource is configured with multiple port numbers, step 402 is executed; if each CSI-RS resource is configured with 1 port number, step 405 is executed.

[0090] In step 402, at least some of the multiple port numbers are used as multiple target port numbers.

[0091] It should be noted here that in the case where multiple port numbers are included in the port number list of each CSI-RS resource, the multiple port numbers are used as multiple target port numbers.

[0092] 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 from the multiple port numbers determined by the maximum port number as multiple target port numbers.

[0093] In step 403, multiple first sub-configuration information corresponding one-to-one to the multiple target port numbers is generated according to the multiple CSI-RS resources, where each first sub-configuration information includes the corresponding target port number.

[0094] In some embodiments, each first sub-configuration information further includes the resource identifier of each CSI-RS resource.

[0095] In step 404, one or more transmit power offset values are configured for each first sub-configuration information.

[0096] For example, in a resource set, there are 2 CSI-RS resources, namely CSI-RS#1 and CSI-RS#2. The port numbers configured for CSI-RS#1 are {8, 12, 16}, and the power control offset value range is [-2, 0] dB. The port numbers configured for CSI-RS#2 are {8, 12, 16}, and the power control offset value range is [-1, 1] dB.

[0097] Generate the following three sub-configuration information in the CSI reporting configuration.

[0098] sub#1 (#ports = 8): {CSI-RS #1, #2}

[0099] sub#2 (#ports = 12): {CSI-RS #1, #2}

[0100] sub#3 (#ports = 16): {CSI-RS #1, #2}

[0101] It should be noted that since each sub-configuration information includes the resource identifiers of the same CSI-RS resources, each sub-configuration information may not include the resource identifiers of the CSI-RS resources.

[0102] 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 send the configured transmit power offset values {-2}, {-2, 0}, {1} to the user terminal. The user terminal determines the CSI-RS resources to be detected based on the above three sub-configuration information and the transmit power offset values configured for each sub-configuration information as follows:

[0103] CSI-RS#1, port 8, transmit power offset value is -2dB

[0104] CSI-RS#1, port 12, transmit power offset value is -2dB

[0105] CSI-RS#1, port 12, transmit power offset value is 0dB

[0106] CSI-RS#2, port 12, transmit power offset value is 0dB

[0107] CSI-RS#2, port 16, transmit power offset value is 1dB

[0108] For another example, in a resource set, there are 2 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.

[0109] Among the multiple port numbers determined by the maximum port number of 16, select three port numbers, namely {8, 12, 16}, and then generate the following three sub-configuration information in the CSI reporting configuration.

[0110] sub#1 (#ports = 8): {CSI-RS #1, #2}

[0111] sub#2 (#ports = 12): {CSI-RS #1, #2}

[0112] sub#3 (#ports = 16): {CSI-RS #1, #2}

[0113] It should be noted that since the resource identifiers of the same CSI-RS resources are included in each sub-configuration information, each sub-configuration information may not include the resource identifiers of the CSI-RS resources.

[0114] Next, among 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 values configured for each sub-configuration information, the CSI-RS resources to be detected by the user terminal are as follows:

[0115] CSI-RS#1, port 8, transmit power offset value is -2 dB

[0116] CSI-RS#1, port 12, transmit power offset value is -2 dB

[0117] CSI-RS#1, port 12, transmit power offset value is 0 dB

[0118] CSI-RS#2, port 12, transmit power offset value is 0 dB

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

[0120] In step 405, it is judged whether each CSI-RS resource is configured with multiple power control offset values.

[0121] If each CSI-RS resource is configured with multiple power control offset values, step 406 or step 408 can be executed according to the preset configuration. If each CSI-RS resource includes 1 power control offset value, step 409 is executed.

[0122] In step 406, a plurality of second sub-configuration information is generated according to a plurality of CSI-RS resources, where each second sub-configuration information includes a resource identifier of at least one CSI-RS resource among the plurality of 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.

[0123] In step 407, one or more transmit power offset values are configured for each second sub-configuration information.

[0124] For example, in a resource set, there are 2 CSI-RS resources, namely CSI-RS#1 and CSI-RS#2. The number of ports configured for both CSI-RS#1 and CSI-RS#2 is 16 (with different port patterns). 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.

[0125] The following three sub-configuration information is generated in the CSI reporting configuration.

[0126] sub#1 (power-offset = -3):{CSI-RS #1}

[0127] sub#2 (power-offset = -2, -1, 1, 2, 3):{CSI-RS #1, #2}

[0128] sub#3 (power-offset = 4, 5):{CSI-RS #2}

[0129] Next, among 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}, {5} are sent to the user terminal. The user terminal determines the CSI-RS resources to be detected based on the above three sub-configuration information and the transmit power offset value configured for each sub-configuration information as follows:

[0130] CSI-RS#1, port 16, transmit power offset value is -3dB

[0131] CSI-RS#1, port 16, transmit power offset value is 2dB

[0132] CSI-RS#2, port 16, transmit power offset value is 2dB

[0133] CSI-RS#2, port 16, transmit power offset value is 5dB

[0134] In step 408, one or more transmit power offset values are configured for each CSI-RS resource.

[0135] For example, in a resource set, there are 2 CSI-RS resources, namely CSI-RS#1 and CSI-RS#2. The number of ports configured for both CSI-RS#1 and CSI-RS#2 is 16 (with different port patterns). The power control offset value range for CSI-RS#1 is [-3, 3] dB. The power control offset value range for CSI-RS#2 is [-2, 5] dB.

[0136] Next, the transmit power offset values configured for CSI-RS#1 and CSI-RS#2 are {-3}, {2}, {5}. Then the configured transmit power offset values {-3}, {2}, {5} are sent to the user terminal. Based on the transmit power offset values {-3}, {2}, {5} configured for CSI-RS#1 and CSI-RS#2, the user terminal determines the CSI-RS resources to be detected as follows:

[0137] CSI-RS#1, port 16, transmit power offset value is -3 dB

[0138] CSI-RS#1, port 16, transmit power offset value is 2 dB

[0139] CSI-RS#2, port 16, transmit power offset value is 2 dB

[0140] CSI-RS#2, port 16, transmit power offset value is 5 dB

[0141] In step 409, it is processed according to the existing preset standard process.

[0142] Since the existing standard process is known to those skilled in the art, it will not be described in detail here.

[0143] Return Figure 1 . In step 103, the CSI reporting configuration result is sent to the user terminal.

[0144] 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. Thus, while completing multiple CSI measurements, the network burden can be effectively reduced and the measurement complexity can be lowered.

[0145] In addition, the present disclosure obtains a more flexible resource allocation method with a smaller overhead, thereby having higher flexibility and a smaller granularity, and effectively improving the resource allocation efficiency.

[0146] Figure 5 FIG. is a schematic structural diagram of a resource allocation device according to an embodiment of the present disclosure. As Figure 5 shown, the resource allocation device includes a first processing module 51 and a second processing module 52.

[0147] The first processing module 51 is configured to perform resource allocation on each CSI-RS resource among a plurality of CSI-RS resources to obtain a resource allocation result, where 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.

[0148] It should be noted that each CSI-RS resource has the same number of ports.

[0149] In some embodiments, the first processing module 51 is configured to determine whether to configure a preset number of ports for the i-th CSI-RS resource among a plurality of CSI-RS resources, , N is the total number of a plurality of CSI-RS resources. If the preset number of ports is configured for the i-th CSI-RS resource, the first processing module 51 writes the preset number of ports in the port number list of the i-th CSI-RS resource, or writes the maximum value of the preset 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.

[0150] For example, the preset value is 1.

[0151] In some embodiments, the first processing module 51 is configured to determine whether to configure a preset number of power control offset values for the i-th CSI-RS resource. If the preset number of power control offset values is configured for the i-th CSI-RS resource, the first processing module 51 writes the preset number of power control offset values in the power list of the i-th CSI-RS resource, or configures the upper limit and lower limit of the power control offset value of the preset number of power control offset values for the i-th CSI-RS resource.

[0152] The second processing module 52 is configured to perform CSI reporting configuration on a plurality of CSI-RS resources according to the resource allocation result to obtain a CSI reporting configuration result, and send the CSI reporting configuration result to the user terminal.

[0153] 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 some of the multiple port numbers are used as multiple target port numbers, and multiple first sub-configuration information items corresponding one-to-one to the multiple target port numbers are generated according to the multiple CSI-RS resources, where each first sub-configuration information item includes the corresponding target port number, and one or more transmit power offset values are configured for each first sub-configuration information item.

[0154] In some embodiments, each first sub-configuration information item further includes the resource identifier of each CSI-RS resource among the multiple CSI-RS resources.

[0155] 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.

[0156] In this case, the multiple port numbers are used as multiple target port numbers.

[0157] In some embodiments, the second processing module 52 is configured to, if the port number list of each CSI-RS resource only includes 1 port number, determine whether the multi-pattern flag of each CSI-RS resource is a preset value. For example, the preset value is 1.

[0158] If the multi-pattern flag of each CSI-RS resource is the preset value, the second processing module 52 determines that each CSI-RS resource includes multiple port numbers, and uses the 1 port number included in the port number list as the maximum port number.

[0159] In this case, a predetermined number of port numbers are selected as multiple target port numbers.

[0160] In some embodiments, the second processing module 52 is configured to, if each CSI-RS resource only includes 1 port number, determine whether each CSI-RS resource is configured with multiple power control offset values. If each CSI-RS resource includes multiple power control offset values, the second processing module 52 generates multiple second sub-configuration information items according to the multiple CSI-RS resources, where each second sub-configuration information item includes the resource identifier of at least one CSI-RS resource among the multiple CSI-RS resources, and the 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 items, and one or more transmit power offset values are configured for each second sub-configuration information item.

[0161] In some embodiments, the second processing module 52 is configured to determine whether each CSI-RS resource is configured with multiple power control offset values if each CSI-RS resource includes only one port number. If each CSI-RS resource includes multiple power control offset values, the second processing module 52 configures one or more transmit power offset values for each CSI-RS resource.
