Description

[0002] In a 5G network, the energy consumption of a single base station can reach more than three times that of an LTE (Long Term Evolution) base station. In addition, due to the higher spectrum and greater density of 5G networks, the total energy consumption of 5G networks is close to four times that of LTE, and the energy consumption cost accounts for nearly half of the total network operation cost. Reducing antenna power is an important direction to reduce the overall energy consumption of the network, thereby reducing the operating costs of 5G networks.

[0003] By measuring multiple CSI-RS (Channel State Information Reference Signal) resources at the same time, the terminal reports multiple CSIs to the base station, thereby adjusting the antenna distribution and transmit power of the base station to reduce network energy consumption. However, the terminal needs to measure and report each antenna distribution and transmit power of the CSI-RS resource. Too much CSI reported at one time will increase the terminal and network feedback overhead, and the efficiency of CSI feedback needs to be further improved. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all 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 invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] 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 invention unless specifically stated otherwise.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] After analysis, it was found that 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. However, in order to achieve such flexible adjustment, the CSI feedback mechanism needs to be enhanced accordingly.

[0041] The embodiments of the present invention support the configuration of one or more CSI-RS resources in the indication of a CSI report configuration (CSI Report Configuration) for the terminal to measure and report. In this way, the network energy consumption and waste of network resources caused by sending signals multiple times can be saved. The embodiments of the present invention can pre-configure multiple CSI-RS resources, and correspondingly, the corresponding parameters can also be set in the CSI report configuration configured by RRC. The base station can select and indicate part of the CSI for measurement and reporting as needed, thereby improving the CSI feedback efficiency.

[0042] To facilitate specific configuration, sub-configuration can be introduced in the CSI reporting configuration, and each sub-configuration can be associated with one or more resources. After the base station selects the sub-configuration for indication, the terminal can know the corresponding resource configuration, so as to perform measurement and reporting. Figure 1 An embodiment of the indication method configured by the present invention is described.

[0043] Figure 1 FIG. 2 is a flow chart showing a configuration indication method according to some embodiments of the present invention. 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 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 a triggered sub-configuration for channel measurement. The triggered sub-configuration is a sub-configuration selected by the base station, which is activated, and the resources associated with the triggered sub-configuration (e.g., CSI-RS resources) need to be measured and reported by the terminal.

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

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

[0047] As needed, technicians in this field 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 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 shows the bitmap and its 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 indication field, has 8 bits, from the most significant bit (MSB) to the least significant bit (LSB), which correspond to sub-configuration #0 to #7. The value of the bitmap in Table 1 indicates 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 Subconfiguration Number #0 #1 #2 #3 #4 #5 #6 #7

[0051] In some embodiments, the sub-configuration corresponding to each bit of the bitmap represents a sub-configuration under a number of antenna ports. For example, when multiple configurations of the number of ports are included in a resource at the same time, the corresponding relationship between the number of ports and the sub-configuration can be pre-configured, and the base station can select the triggered sub-configuration based on the number of ports and indicate it.

[0052] For example, in the RRC (Radio Resource Control) configuration of CSI Resource configuration, in the CSI-RS resource set (Resource Set), the resources CSI-RS#1 and CSI-RS#2 are included. These two resources are configured with 2 port numbers (port), for CSI-RS#1, the configured port number includes {4,8}; for CSI-RS#2, the configured port number includes {8,12}. Then, there are 3 sub-configurations in the CSI reporting configuration, which are:

[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 length of the bitmap corresponding to the three sub-configurations is, for example, 3 bits, corresponding to sub#1, sub#2, and sub#3 from the most significant bit to the least significant bit. When the target value is 1, if the value of the bitmap is 010 in the indication of the base station, it means that the sub-configuration corresponding to the second bit of the target value is triggered, that is, the sub-configuration sub#2 corresponding to the port number 8 is triggered.

[0057] In some embodiments, the sub-configuration corresponding to each bit of the bitmap represents a sub-configuration under a transmit power offset. For example, when multiple configurations under transmit power offsets are included in a resource at the same time, the correspondence between the transmit power offset and the sub-configuration can be pre-configured, and the base station can select the triggered sub-configuration based on the transmit power offset and indicate it.

[0058] For example, in the RRC (Radio Resource Control) configuration of CSI Resource configuration, in the CSI-RS resource set (Resource Set), the resources CSI-RS#1 and CSI-RS#2 are included. These two resources are configured with 2 transmit power offsets (Offsets), for CSI-RS#1, the configured transmit power offset includes {-3dB, 1dB}; for CSI-RS#2, the configured transmit power offset includes {1dB, 3dB}. Then, there are 3 sub-configurations in the CSI reporting configuration, which are:

[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 length of the bitmap corresponding to the three sub-configurations is, for example, 3 bits, corresponding to sub#1, sub#2, and sub#3 from the most significant bit to the least significant bit. When the target value is 1, if the value of the bitmap is 100 in the indication of the base station, it means that the sub-configuration corresponding to the first bit of the target value is triggered, that is, the sub-configuration sub#1 corresponding to the transmit power offset -3dB is triggered.

[0063] In some embodiments, the bitmap includes a first part and a second part, each bit in the first part represents a sub-configuration under a number of antenna ports, and each bit in the second part represents information about resources used to measure using the triggered sub-configuration. The resource information is, for example, a transmit power offset value. As required, it may also be other information related to the configuration. Thus, a sub-configuration can be constructed based on the number of antenna ports, and the sub-configuration can be further indicated based on other information to support the indication of sub-configurations in multiple dimensions.

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

[0065] Table 2

[0066]

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

[0068] In the channel state information reporting configuration, each sub-configuration may correspond to a configuration under a number of antenna ports, and each sub-configuration corresponds to 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 order or descending order.

[0069] In the channel state information reporting configuration, each sub-configuration may correspond to a configuration under a transmit power offset, and each sub-configuration corresponds to a different transmit power offset. 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 in ascending order 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, and then these sub-configurations are arranged in a certain manner (such as ascending or descending order) according to the sub-configuration identifier. The arrangement order of the sub-configuration corresponds to the arrangement order of the corresponding bits of the sub-configuration in the bitmap. For example, the sub-configuration arranged in the first place corresponds to the first bit in the bitmap. By adding a sub-configuration identifier, it is convenient to indicate the sub-configuration to be used when the sub-configuration is applied to other scenarios. The sub-configuration identifier is determined, for example, according to the reference dimension of the sub-configuration, such as indicating the number of ports, the transmit power offset value, etc. In addition, it is also possible not to explicitly add the sub-configuration identifier in the channel state information reporting configuration, but to directly sort according to the reference dimension included in the sub-configuration, so as to reduce the amount of data of the configuration information.

[0071] The above-mentioned method of determining the correspondence between the sub-configuration and the bit in the bitmap based on the sorting result can improve the search and processing efficiency of the base station and the terminal in the process of determining the correspondence between the bit in the bitmap and the sub-configuration. Of course, it should be clear to those skilled in the art that the one or more configured sub-configurations can also be arranged in any other manner, which will not be repeated here.

[0072] In some embodiments, the base station sends a bitmap for configuration to the terminal through RRC signaling, DCI (Downlink Control Information) or MAC CE (Medium Access Control Control Element). For example, for a sub-configuration of an aperiodic non-zero power channel state information indication signal (Aperiodic None Zero Power CSI-RS, referred to as: A-CSI) resource or a semi-persistent non-zero power channel state information indication signal (Semi-Persistent None Zero Power CSI-RS, referred to as: SP-CSI) resource, an indication can be sent through 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 one time in a bitmap manner, thereby reducing the complexity and network overhead of the terminal measuring the reference signal, and improving the flexibility and reliability of parameter configuration and the CSI feedback efficiency. The embodiments of the present invention can realize the indication and selection of multiple sub-configurations, for example, it is applicable to the case of flexibly selecting antenna port shutdown and transmission power.

[0074] After the base station sends the instruction, the terminal can perform corresponding measurements and reports. Figure 2 FIG. 2 is a flow chart showing a configuration indication method according to some other embodiments of the present invention. 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 a triggered sub-configuration for channel measurement.

[0076] In step S104, the terminal performs measurement 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 subconfiguration indicated by the bitmap according to the correspondence between the bitmap bits and the subconfiguration explicitly or implicitly indicated in the CSI reporting configuration. In addition, the terminal can also determine the starting position of the bitmap used for configuration indication based on the length information of the pre-configured bitmap.

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

[0079] Through the above embodiments, when selecting and indicating multiple resources, the base station can indicate the triggering of one or more sub-configurations at one time in the form of a bitmap, and the terminal can also realize one-time reporting of multiple measurement results, thereby reducing the complexity and network overhead of the terminal measuring the reference signal, and improving the flexibility and reliability of parameter configuration and the CSI feedback efficiency.
