Description

Technical Field

[0001] [Cross-reference to Related Applications] This disclosure claims the priority of a Chinese patent application filed on August 11, 2023, with application number 202311013889.2 and invention title "Method, Apparatus, Network Device, Terminal, and Storage Medium for Selecting Reporting Sub-configurations", and the entire content of the Chinese patent application is incorporated herein by reference.

[0002] This disclosure relates to the technical field of wireless communication, and in particular, to a method for selecting channel state information reference signal measurement reporting sub-configurations, an apparatus for selecting channel state information reference signal measurement reporting sub-configurations, a network device, and a computer-readable storage medium.

Background Art

[0003] Since the total power consumption of a 5G (5th Generation Mobile Communication Technology) network is nearly four times that of LTE (Long Term Evolution), it has become an urgent task to reduce the overall power consumption of the 5G network, and reducing the power consumption of antennas is an important direction in reducing the overall power consumption of the network.

[0004] By flexibly shutting down antenna ports and adjusting transmit power, antenna power consumption can be reduced, thereby lowering network power consumption during base station signal transmission. To achieve such flexible adjustment, it is necessary to strengthen the CSI (channel state information) feedback mechanism. By implementing multiple CSI-RS (Channel State Information-Reference Signal) resource placements within a single CSI configuration, measurement and reporting by the UE (User Equipment) becomes possible. However, reporting all multiple CSI measurement results will impact the complexity and power consumption of the UE.

[0042] The exemplary embodiments will be described more fully below with reference to the drawings. However, the exemplary embodiments can be implemented in multiple forms and should not be understood as being limited to the examples described herein. Rather, the purpose of providing these embodiments is to make this disclosure more comprehensive and complete and to fully convey the idea of ​​the exemplary embodiments to those skilled in the art. The features, structures or characteristics described can be combined in any suitable way in one or more embodiments.

[0043] Furthermore, the drawings are merely schematic representations of the present disclosure and are not necessarily drawn to scale. Identical reference numerals in the drawings indicate the same or similar parts, and therefore redundant explanations are omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software form, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0044] In the form provided by this disclosure, when data analysis of target case reports is required, identifying the target case report CSI-RS (Channel State Information-Reference Signal) is an extremely important reference signal in 5GNR (New Radio, i.e., 5G wireless network) systems. Because radio channel conditions can constantly change, terminals need to feed back observed downlink channel conditions to base stations using CSI (Channel State Information). This allows base stations to flexibly perform actions such as shutting down antenna ports or adjusting antenna transmission power while considering channel quality during downlink scheduling. The three components, Channel Quality Indicator (CQI), Rank Indicator (RI), and Precoder Matrix Indicator (PMI), are collectively referred to as Channel State Information CSI.

[0045] Because 5G networks consume more power than 4G networks, this impacts the operating costs of 5G networks, making it necessary to reduce 5G power consumption. Furthermore, by simultaneously deploying multiple CSI resources for measurement and reporting, antenna shutdown and transmission power can be flexibly adjusted, effectively reducing the power consumption of base station antennas. However, having a terminal perform multiple CSI measurements and reports simultaneously increases terminal complexity and dramatically increases CSI reporting costs. To prevent these negative effects, it is necessary to select which CSI resources to measure and report.

[0046] The following describes in more detail each step of the method for selecting the channel state information reference signal measurement report subconfiguration in this embodiment, with reference to the drawings and examples.

[0047] Figure 1 shows a flowchart illustrating the method for selecting a channel state information reference signal measurement report subconfiguration in an embodiment of the present disclosure.

[0048] As shown in Figure 1, according to one embodiment of the channel state information reference signal measurement report subconfiguration selection method of the present disclosure, the channel state information reference signal measurement report subconfiguration selection method is applied to a base station. The procedure includes step S102, which involves sending a selection list of multiple Channel status information CSI reporting subconfigurations to a terminal, using the selection list to select at least one of the multiple CSI reporting subconfigurations, and having the terminal perform CSI measurement and reporting based on the selected CSI reporting subconfiguration.

[0049] A CSI reporting subconfiguration is used to configure reporting for at least one CSI-RS resource. A CSI subconfiguration refers to a set of CSI-RS resources that share the same characteristics, which may include having the same number of antenna ports or the same transmit power offset.

[0050] The method of selecting instructions in the selection list may be a direct instruction for one or more CSI reporting subconfigurations, or an instruction for limiting the scope of a subconfiguration. Assuming there are N CSI reporting subconfigurations, the selection list can contain at most N instruction identifiers, or a set {n|X≦n≦Y}. This indicates that the subconfiguration must be enabled and the corresponding placement of the associated CSI-RS resources must be measured and reported by the terminal UE.

[0051] In this embodiment, by setting up a selection list, the reporting subconfigurations selected in the selection list are placed based on the configuration, the CSI-RS resources to be placed are identified based on the selected reporting subconfigurations, and CSI measurements and reports are performed for the CSI-RS placement in the CSI reporting subconfiguration, or for the subconfiguration consisting of multiple CSI-RS resource placements. This enables instruction and selection of CSI-RS subconfigurations, allows for flexible selection of antenna ports and transmit power, contributes to reducing the complexity of reference signal measurement at the user terminal and network overhead, and improves the flexibility and requestability of CSI-RS measurement resource placement.

[0052] In one embodiment, multiple CSI reporting subconfigurations are arranged based on a CSI reporting subconfiguration mechanism. Each arranged CSI reporting subconfiguration corresponds to multiple channel state information reference signal CSI-RS resources having the same characteristics.

[0053] A single reporting sub-configuration contains multiple CSI-RS resources. Furthermore, the placement of each CSI-RS resource exists within only one CSI reporting sub-configuration.

[0054] In one embodiment, the selection list includes at least one selection identifier or records a numerical range of selection identifiers. The selection identifier is used to indicate the selected CSI reporting sub-configuration.

[0055] In this embodiment, by placing a selection identifier in the selection list to indicate the selected CSI reporting subconfiguration, it is possible to further identify the CSI-RS resources to be deployed based on the CSI reporting subconfiguration. This eliminates the need for the terminal to measure the CSI-RS resources for all deployments, thereby reducing network power consumption.

[0056] In one embodiment, in the CSI reporting arrangement in wireless resource control RRC signaling, corresponding sub-identifiers and reporting sub-configurations are arranged.

[0057] In one embodiment, the selection identifier includes the sub-identifier of the CSI reporting sub-configuration.

[0058] In RRC resource deployment, a sub-identifier (sub-ID) is added for each reporting sub-configuration. In this case, the sub-ID may be used directly as the selection identifier.

[0059] In this embodiment, if a predetermined sub-identifier (sub-ID) is included in the list, it indicates the activation of the corresponding reporting sub-configuration, and the corresponding placement of the associated CSI-RS resource must be measured and reported by the UE. This ensures flexibility and delegation of choice.

[0060] In one embodiment, the selection identifier includes a first sort number that sorts the sub-identifiers of the CSI reporting sub-configuration.

[0061] In this embodiment, in order to reduce the number of bits occupied by the direct use of sub-identifiers sub-IDs, the sub-identifiers sub-IDs are arranged and numbered in a predetermined format. For example, the first sort number obtained by numbering the sub-identifiers sub-IDs in ascending or descending order is used as the selection identifier. The corresponding sub-configuration can be identified by the first sort number.

[0062] In one embodiment, the same feature refers to the fact that multiple CSI-RS resources have the same number of antenna ports. The selection list includes a first selection list. The first selection list includes at least one first selection identifier generated based on the selection of the number of antenna ports.

[0063] Exemplary, in one embodiment, the generation of a first selection identifier based on the selection of the number of antenna ports includes obtaining a second sort number by sorting the number of antenna ports corresponding to multiple CSI reporting sub-configurations, and the first selection identifier includes the second sort number.

[0064] In this embodiment, it is not necessary to associate a sub-ID with the CSI report subconfiguration. In this case, it is also possible to obtain a second sort number by directly arranging the number of antenna ports in ascending / descending order, and then select the corresponding sub-configuration by directly using this second sort number as the first selection identifier.

[0065] Exemplary, in another embodiment, the generation of a first selection identifier based on the selection of the number of antenna ports includes the first selection identifier including the number of antenna ports.

[0066] The number of antenna ports in a CSI-RS resource can be a single antenna port or multiple antenna ports, with a maximum of 32 antenna ports possible. Code Division Multiplexing (CDM) is used for mapping multiple antenna ports. That is, multiple CSI-RS resources can be identified and mapped using the CDM method within the same time-frequency resource.

[0067] In this embodiment, for multiple CSI-RS resources arranged to correspond to different antenna ports, the number of antenna ports associated with a sub-configuration can be used as a unique identifier because CSI-RS resources corresponding to the same sub-configuration have the same number of ports. By entering a specific number of ports in the list, different sub-configurations can be specified.

[0068] Furthermore, it should be understood that, in addition to adding a specific number of antenna ports to the list, it is also possible to change the contents of the list to a numerical range for the number of ports, thereby allowing all sub-configurations in which the number of antenna ports falls within that range to be specified.

[0069] In one embodiment, the same feature refers to the fact that multiple CSI-RS resources have the same transmit power offset value. The selection list includes a second selection list. The second selection list includes at least one second selection identifier, the second selection identifier is generated based on the selection of the transmit power offset value.

[0070] In this embodiment, when a CSI-RS resource exists that simultaneously includes multiple port counts and transmit power offset values, the CSI reporting subconfiguration can be identified solely by the number of ports. However, even in this case, the selection of the transmit power offset remains possible. This assists in indicating the CSI-RS to be ultimately measured and reported. In this case, the power offset of the selected CSI-RS can be directly selected.

[0071] The transmit power offset list can reuse the subconfiguration selection list field based on transmit power.

[0072] In one embodiment, multiple transmit power offset values ​​corresponding to multiple CSI reporting sub-configurations are sorted to obtain a third sort number, and a second selection identifier includes the third sort number.

[0073] In one embodiment, the second selection identifier includes a transmit power offset value.

[0074] As shown in Figure 2, in one embodiment, sending a selection list of multiple channel status information CSI report sub-configurations to the terminal is: Step S202 includes sending RRC signaling to the terminal that carries multiple CSI reporting sub-configurations and selection lists.

[0075] In one embodiment, after sending RRC signaling to the terminal, The process further includes step S204, which involves sending a CSI trigger signaling to a terminal, which then performs CSI measurement and reporting for a selected CSI reporting sub-configuration based on the CSI trigger signaling. The CSI trigger signaling includes media access control MAC control cell CE and / or downlink control information DCI.

[0076] NR supports three reporting types: periodic CSI, semi-persistent NZP-CSI (SP-CSI), and aperiodic NZP-CSI (A-CSI). P-CSI means that no trigger is required after RRC signaling is set up; that is, periodic measurement and reporting start immediately after RRC signaling is set up. The difference between SP-CSI and P-CSI lies in the need for a trigger. SP-CSI means that after setting up basic information with RRC signaling, the system waits until the gNB retransmits trigger information before starting periodic measurement and transmission, and no reporting is required until the trigger signal is received. A-CSI means that one report is performed for each trigger.

[0077] As shown in Figure 3, in one embodiment, sending a selection list of multiple channel status information CSI report sub-configurations to the terminal is: Step S302 involves sending RRC signaling to the terminal, which carries multiple CSI reporting sub-configurations. Step S304 includes sending a CSI trigger signaling carrying a selection list to a terminal, and the terminal performing CSI measurements and reporting for the selected CSI reporting sub-configuration based on the CSI trigger signaling. The CSI trigger signaling includes MAC CE and / or DCI.

[0078] In this embodiment, the selection fields applicable to aperiodic NZP-CSI (A-CSI) and semi-persistent NZP-CSI (SP-CSI) may be located in the DCI or MAC CE that activates the CSI reporting, and the specific numerical values ​​that can be selected can be automatically obtained from the CSI-RS resource placement already set up in the RRC.

[0079] When introducing sub-configuration IDs, they should be placed together with the sub-configuration in the RRC deployment of the CSIreport configuration.

[0080] The present invention remains applicable even when more dimensions of sub-configuration are introduced. In this case as well, the sub-configuration based on the number of ports is used as the selection criterion, and other instruction fields perform further instructions only for that CSI-RS.

[0081] Even in the absence of a sub-configuration mechanism, the method of this invention allows for direct selection based on the configuration arrangement.

[0082] As shown in Figure 4, the method for selecting a channel state information reference signal measurement report sub-configuration in another embodiment of this disclosure is applied to a terminal. Step S402 involves receiving a selection list of multiple channel state information CSI report subconfigurations transmitted from the base station, and using the selection list to select at least one of the multiple CSI report subconfigurations, Step S404 includes performing CSI measurements and reporting based on a selected CSI reporting sub-configuration.

[0083] In this embodiment, by receiving a selection list placed on the base station side, the system places the reporting subconfiguration selected in the selection list based on the placement configuration. Based on the selected reporting subconfiguration, it identifies the CSI-RS resource to be placed and performs CSI measurement and reporting for the CSI-RS placement in the CSI reporting subconfiguration, or for the subconfiguration composed of multiple CSI-RS resource placements. This enables instruction and selection of CSI-RS subconfigurations, allows for flexible selection of antenna ports and transmit power, and contributes to reducing the complexity of terminal reference signal measurement and reducing network overhead.

[0084] In one embodiment, multiple CSI reporting subconfigurations are arranged based on a CSI reporting subconfiguration mechanism. Each arranged CSI reporting subconfiguration corresponds to multiple CSI-RS resources having the same characteristics. Receiving a selection list of multiple channel state information CSI reporting subconfigurations transmitted from a base station further includes extracting a selection identifier or a numerical range of selection identifiers from the selection list, and selecting at least one of the multiple CSI reporting subconfigurations based on the selection identifier or numerical range.

[0085] In one embodiment, the selection identifier includes the sub-identifier of the CSI reporting sub-configuration.

[0086] In one embodiment, the selection identifier includes a first sort number that sorts the sub-identifiers of the CSI reporting sub-configuration.

[0087] In one embodiment, receiving RRC signaling transmitted from a base station further includes extracting the corresponding sub-identifier and sub-configuration in the CSI reporting arrangement of the RRC signaling, identifying the selected sub-configuration based on the sub-identifier selected from a selection list, and measuring the CSI-RS resource corresponding to the sub-configuration.

[0088] In one embodiment, a common feature is that multiple CSI-RS resources have the same number of antenna ports. The selection list includes a first selection list. At least one first selection identifier is extracted from the first selection list, and the first selection identifier is either the number of antenna ports or a second sort number. The second sort number is generated by sorting multiple antenna port numbers corresponding to multiple CSI reporting sub-configurations.

[0089] In one embodiment, the identical feature is that multiple CSI-RS resources have the same transmit power offset value. The selection list includes a second selection list, which includes at least one second selection identifier, where the second selection identifier is either a transmit power offset value or a third sort number. The third sort number is generated by sorting multiple transmit power offset values ​​corresponding to multiple CSI reporting subconfigurations.

[0090] In one embodiment, performing CSI measurement and reporting based on a selected CSI reporting subconfiguration includes making a CSI-RS resource that satisfies both a first selection list and a second selection list the CSI-RS resource corresponding to the selected CSI reporting subconfiguration.

[0091] For example, suppose there are three CSI reporting sub-configurations with selection identifiers #0, #1, and #2, corresponding to 16, 8, and 24 antenna ports, respectively. In this case, the placement information in the selection list is {#0,#1} or {16,8}, and the placement power offset list is {#0,#2} or {-3,3}. This indicates that the sub-configuration with 16 / 8 ports is selected. However, by simply measuring and reporting the CSI-RS among them, which can be set to a transmit power offset value of 3 / -3, the CSI-RS resources in both the first and second selection lists will be satisfied.

[0092] In one embodiment, receiving a selection list of multiple channel state information CSI reporting sub-configurations transmitted from a base station includes receiving RRC signaling transmitted from the base station that carries multiple CSI reporting sub-configurations and a selection list.

[0093] In one embodiment, the process includes receiving RRC signaling transmitted from a base station, then receiving CSI trigger signaling transmitted from the base station, and performing CSI measurement and reporting for a selected CSI reporting sub-configuration based on the CSI trigger signaling. The CSI trigger signaling includes media access control MAC control cell CE and / or downlink control information DCI.

[0094] In one embodiment, receiving a selection list of multiple channel state information CSI reporting subconfigurations transmitted from a base station includes receiving an RRC signaling transmitted from the base station and carrying multiple CSI reporting subconfigurations, and receiving a CSI trigger signaling transmitted from the base station and carrying a selection list, and performing CSI measurement and reporting for the selected CSI reporting subconfigurations based on the CSI trigger signaling. The CSI trigger signaling includes media access control MAC control cell CE and / or downlink control information DCI.

[0095] As shown in Figure 5, the method for selecting another channel state information reference signal measurement reporting subconfiguration of the present disclosure is: Step S502 involves deploying CSI-RS resources to the terminal using CSI-ResourceConfig, Step S504 involves placing multiple CSI reporting subconfigurations and corresponding subidentifiers on the terminal, and each CSI reporting subconfiguration corresponds to multiple CSI-RS resources having the same characteristics. Step S506 includes identifying a selected sub-identifier based on a selection list sent to the terminal, and, based on the selected sub-identifier, having the terminal perform the corresponding CSI measurement and reporting when DCI or MAC CE signaling is triggered and activated.

[0096] In a further embodiment of the present disclosure, a method for selecting a channel state information reference signal measurement reporting subconfiguration is performed, which involves dynamic adjustment of the antenna port based on CSI feedback.

[0097] To achieve energy savings through dynamic adjustment of network antennas, an enhanced CSI feedback mechanism is introduced. In the RRC arrangement of the CSIResource configuration, two ports are allocated to each of the two CSI-RS resources within the CSI-RSResourceSet. The number of ports for CSI-RS#1 is {4,8}, and the number of ports for CSI-RS#2 is {8,12}, forming a total of three subconfigurations, as follows. sub#1(#port=4):{CSI-RS#1} sub#2(#port=8):{CSI-RS#1,CSI-RS#2} sub#3(#port=12):{CSI-RS#2}

[0098] When triggered by MAC CE, the list contents are {#2}, and only measurements and reports for the CSI-RS placement within sub#2 are required.

[0099] In a further embodiment of the present disclosure, a method for selecting a channel state information reference signal measurement reporting subconfiguration is performed, which involves dynamic adjustment of antenna ports and transmit power joints based on CSI feedback.

[0100] To achieve energy savings through dynamic adjustment of network antennas and power, an enhanced CSI feedback mechanism is introduced. In the RRC arrangement of the CSIResource configuration, within a CSI-RSResourceSet, two CSI-RSs are placed within one CSI-RS resource, corresponding to CSI-RSs with 32 and 16 ports respectively, with the adopted transmit power offsets {1dB(#1) and 3dB(#2)}.
