Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a configuration indication method, apparatus, system, and computer-readable storage medium. Background Technology

[0002] In 5G networks, the energy consumption of a single base station can be more than three times that of an LTE (Long Term Evolution) base station. Furthermore, due to the higher spectrum and density of 5G networks, the total energy consumption of 5G networks is nearly four times that of LTE, with energy costs accounting for almost half of the total network operating costs. Reducing antenna power is a crucial direction for lowering overall network energy consumption, thereby reducing the operating costs of 5G networks.

[0003] By simultaneously measuring multiple CSI-RS (Channel State Information Reference Signal) resources and reporting multiple CSIs to the base station, the terminal can adjust the base station's antenna distribution and transmit power, thereby reducing network power consumption. However, the terminal needs to measure and report each antenna distribution and transmit power for each CSI-RS resource. Reporting too many CSIs at once will increase the feedback overhead for both the terminal and the network, and the efficiency of CSI feedback needs to be further improved. Summary of the Invention

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use.

[0036] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0037] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0038] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0040] Analysis revealed that by flexibly shutting down antenna ports and adjusting antenna transmit power, the network power consumption of base station signal transmission can be reduced as much as possible. However, to achieve such flexible adjustments, the CSI feedback mechanism needs to be enhanced accordingly.

[0041] Embodiments of the present invention support the configuration of one or more CSI-RS resources within a single CSI report configuration instruction, enabling terminals to perform measurements and report. This saves network energy consumption and network resource waste caused by multiple signal transmissions. Embodiments of the present invention can pre-configure multiple CSI-RS resources, and corresponding parameters can be set in the CSI report configuration of the RRC. The base station can select and instruct some of these CSIs to perform measurement and reporting as needed, thereby improving CSI feedback efficiency.

[0042] To facilitate specific configurations, sub-configurations can be introduced into the CSI reporting configuration. Each sub-configuration can be associated with one or more resources. After the base station selects a sub-configuration, the terminal can obtain the corresponding resource configuration, thereby performing measurement and reporting. See below for reference. Figure 1 An embodiment of the instruction method configured according to the present invention is described.

[0043] Figure 1 A flowchart illustrating a configuration indication method according to some embodiments of the present invention is shown. Figure 1 As shown, the configuration indication method of this embodiment includes step S102.

[0044] In step S102, the base station sends a bitmap to the terminal, wherein each bit in at least a portion of the bitmap corresponds to a sub-configuration of the channel state information reporting configuration. The bitmap is used to indicate the triggered sub-configurations for channel measurement. The triggered sub-configurations are those selected by the base station, which are activated, and the resources associated with the triggered sub-configurations (e.g., CSI-RS resources) need to be measured and reported by the terminal.

[0045] A bitmap is a string of binary bits, where each bit can be set to 0 or 1. At least some bits in the bitmap can correspond to a sub-configuration. When every bit in the bitmap corresponds to a sub-configuration, the length of the bitmap is the same as the number of all configured sub-configurations. The length information can be configured, for example, in the configured CSI-RS resource configuration information of the RRC.

[0046] In a bitmap, one or more bits set to a target value are used to indicate the triggered sub-configuration. For example, when at least some of the aforementioned bits have a value of the target value (e.g., 1), it indicates that the sub-configuration corresponding to that bit is activated. When there is only one triggered sub-configuration, and this triggered sub-configuration is associated with multiple resources, it is also possible to provide a one-time indication of the configuration of multiple resources. Therefore, regardless of whether the bitmap indicates one or more triggered sub-configurations, it is possible to provide an indication of merging multiple resources.

[0047] As needed, those skilled in the art may also use a combination of multiple bits to represent a sub-configuration. That is, when multiple bits are set to a target value, it means that the sub-configuration corresponding to the combination of these multiple bits is triggered, and the resources associated with the triggered sub-configuration (such as CSI-RS resources) need to be measured and reported by the terminal.

[0048] Table 1 exemplarily illustrates the bitmaps and their values ​​used in some embodiments of the present invention. As shown in Table 1, assuming there are 8 sub-configurations, the bitmap, i.e., the indicator field, has 8 bits. From the most significant bit (MSB) to the least significant bit (LSB), they correspond to sub-configuration #0 to #7 respectively. The bitmap values ​​in Table 1 indicate that sub-configuration #0, sub-configuration #3, sub-configuration #5, and sub-configuration #7 are currently triggered.

[0049] Table 1

[0050] Value 1 0 0 1 0 1 0 1 Sub-configuration number #0 #1 #2 #3 #4 #5 #6 #7

[0051] In some embodiments, each bit of the bitmap corresponds to a sub-configuration representing a sub-configuration under a certain number of antenna ports. For example, when a resource includes configurations for multiple port numbers, the correspondence between port numbers and sub-configurations can be pre-configured, and the base station can select and indicate the triggered sub-configuration based on the port number.

[0052] For example, in the Radio Resource Control (RRC) configuration of the CSI Resource configuration, the CSI-RS Resource Set includes resources CSI-RS#1 and CSI-RS#2. These two resources are each configured with two port numbers: for CSI-RS#1, the configured port numbers are {4, 8}; for CSI-RS#2, the configured port numbers are {8, 12}. Therefore, the CSI reporting configuration forms three sub-configurations:

[0053] sub#1(#port=4):{CSI-RS#1};

[0054] sub#2(#port=8):{CSI-RS#1,CSI-RS#2};

[0055] sub#3(#port=12):{CSI-RS#2}

[0056] The bitmaps corresponding to these three sub-configurations are, for example, 3 bits long, with the most significant bit (LSB) corresponding to sub#1, sub#2, and sub#3 respectively. If the target value is 1, and the bitmap in the base station's indication is 010, it means that the sub-configuration corresponding to the second bit with the target value is triggered, i.e., sub-configuration sub#2 corresponding to port number 8 is triggered.

[0057] In some embodiments, each bit of the bitmap corresponds to a sub-configuration representing a sub-configuration under a transmit power offset. For example, when a resource includes multiple configurations under transmit power offsets, the correspondence between transmit power offsets and sub-configurations can be pre-configured, and the base station can select and indicate the triggered sub-configuration based on the transmit power offset.

[0058] For example, in the Radio Resource Control (RRC) configuration of the CSI Resource configuration, the CSI-RS resource set includes resources CSI-RS#1 and CSI-RS#2. These two resources are each configured with two transmit power offsets: for CSI-RS#1, the configured transmit power offsets include {-3dB, 1dB}; for CSI-RS#2, the configured transmit power offsets include {1dB, 3dB}. Therefore, the CSI reporting configuration forms three sub-configurations:

[0059] sub#1(#Offset=-3dB):{CSI-RS#1};

[0060] sub#2(#Offset=1dB):{CSI-RS#1,CSI-RS#2};

[0061] sub#3(#Offset=3dB):{CSI-RS#2}

[0062] The bitmaps corresponding to these three sub-configurations are, for example, 3 bits long, with the most significant bit (LSB) corresponding to sub#1, sub#2, and sub#3 respectively. If the target value is 1, and the bitmap's value is 100 in the base station's indication, it means that the sub-configuration corresponding to the first bit with the target value is triggered, i.e., the sub-configuration sub#1 corresponding to the transmit power offset of -3dB is triggered.

[0063] In some embodiments, the bitmap includes a first portion and a second portion, where each bit in the first portion represents a sub-configuration for a given number of antenna ports, and each bit in the second portion represents information about resources used for measurement with the triggered sub-configuration. Resource information may include, for example, a transmit power offset value. Other configuration-related information may also be included, as needed. Thus, sub-configurations can be constructed based on the number of antenna ports and further indicated based on other information to support multi-dimensional sub-configuration indication.

[0064] Table 2 exemplarily illustrates the bitmaps and their values ​​used in other embodiments of the present invention. As shown in Table 2, assuming there are four sub-configurations corresponding to the number of antenna ports and three transmit power offsets, the first part of the bitmap, i.e., the indicator field, has four bits, and the second part has three bits. The most significant bit to the least significant bit of the first part corresponds to the sub-configurations corresponding to the number of ports 4, 8, 16, and 32, respectively. The most significant bit to the least significant bit of the second part corresponds to the transmit power offsets of -5dB, -3dB, and 3dB, respectively. The bitmap values ​​in Table 2 indicate that the sub-configurations corresponding to the number of ports 8 and 32 are currently selected, and measurements and reporting are performed on resources with transmit power offsets of -3dB and 3dB.

[0065] Table 2

[0066]

[0067] In some embodiments, the bit corresponding to each sub-configuration in the bitmap is determined according to the order of the sub-configurations in the channel state information reporting configuration.

[0068] In the channel state information reporting configuration, each sub-configuration corresponds to a configuration with a different number of antenna ports. The sub-configurations in the channel state information reporting configuration are arranged according to the number of antenna ports corresponding to each sub-configuration, for example, in ascending or descending order.

[0069] In the channel state information reporting configuration, each sub-configuration can correspond to a configuration under a transmit power offset, and the transmit power offset corresponding to each sub-configuration is different. For example, the sub-configurations in the channel state information reporting configuration are arranged according to the transmit power offset corresponding to each sub-configuration, such as ascending or descending order.

[0070] For example, in the channel state information reporting configuration, a sub-configuration identifier (sub-ID) can be added to each sub-configuration. Then, based on the sub-configuration identifier, these sub-configurations are arranged in a certain way (such as ascending or descending order). The order of the sub-configurations corresponds, for example, to the order of their corresponding bits in a bitmap. For instance, the sub-configuration at the beginning corresponds to the first bit in the bitmap. By adding sub-configuration identifiers, it is easier to indicate which sub-configuration is being used when applying it to other scenarios. The sub-configuration identifier is determined, for example, based on the reference dimension of the sub-configuration, such as representing the number of ports, transmit power offset, etc. Alternatively, the sub-configuration identifier can be omitted from the channel state information reporting configuration; instead, the sub-configuration can be directly sorted according to the reference dimensions it includes, which reduces the amount of configuration information data.

[0071] The method described above for determining the correspondence between sub-configurations and bits in the bitmap based on the sorting results can improve the search and processing efficiency of base stations and terminals in the process of determining the correspondence between bits in the bitmap and sub-configurations. Of course, those skilled in the art should understand that these one or more configured sub-configurations can also be arranged in any other arbitrary way, which will not be elaborated here.

[0072] In some embodiments, the base station sends a bitmap for configuration to the terminal via RRC signaling, DCI (Downlink Control Information), or MAC CE (Medium Access Control Control Element). For example, for sub-configurations of Aperiodic None Zero Power CSI-RS (A-CSI) or Semi-Persistent None Zero Power CSI-RS (SP-CSI) resources, indications can be sent via DCI or MAC CE.

[0073] Through the above embodiments, when selecting and indicating multiple resources, the base station can indicate the triggering of one or more sub-configurations at once using a bitmap, reducing the complexity of the terminal measurement reference signal and network overhead, and improving the flexibility and reliability of parameter configuration as well as CSI feedback efficiency. The embodiments of the present invention can realize the indication and selection of multiple sub-configurations, and are applicable, for example, to situations where antenna port shutdown and transmit power can be flexibly selected.

[0074] After the base station sends the instruction, the terminal can perform the corresponding measurements and report. Figure 2 A flowchart illustrating a configuration indication method according to other embodiments of the present invention is shown. For example... Figure 2 As shown, the configuration indication method of this embodiment includes steps S102 to S106.

[0075] In step S102, the base station sends a bitmap to the terminal, wherein each of at least some bits in the bitmap corresponds to a sub-configuration of the channel state information reporting configuration, and the bitmap is used to indicate the triggered sub-configuration for channel measurement.

[0076] In step S104, the terminal performs measurements based on the triggered sub-configuration. Thus, the terminal measures the associated resources based on one or more triggered sub-configurations indicated by the base station at one time.

[0077] After obtaining the bitmap, the terminal can determine the triggered sub-configuration indicated by the bitmap based on the correspondence between the bits of the bitmap and the sub-configurations explicitly or implicitly indicated in the CSI-reported configuration. Furthermore, the terminal can determine the starting position of the bitmap used for configuration indication based on pre-configured bitmap length information.

[0078] In step S106, the base station receives the measurement results reported by the terminal, wherein the reported measurement results include the measurement results performed by the terminal based on the triggered sub-configuration. Thus, the terminal can report the measurement results of multiple resources to the base station at once.

[0079] Through the above embodiments, when the base station selects and indicates multiple resources, it can indicate the triggering of one or more sub-configurations at one time through a bitmap. The terminal can also report multiple measurement results at one time, which reduces the complexity of the terminal measurement reference signal and network overhead, and improves the flexibility and reliability of parameter configuration and CSI feedback efficiency.
