Description

Technical Field

[0002] According to GSMA statistics, electricity costs account for 23% of total operating costs, with approximately 90% of the energy consumption in wireless access networks concentrated in the Active Antenna Unit (AAU). AAU energy consumption consists of four parts: the power amplifier (PA), digital intermediate frequency (IF) unit, small signal processing unit (SSN), and power module. The energy consumption percentage of each module varies significantly under different service loads: in full load and 30% load scenarios, the PA accounts for 58% and 37% of the AAU's power consumption, respectively, both being the highest among all modules; under no-load conditions, the PA's power consumption percentage drops to 15%, ranking second to last among all AAU modules. Implementing Network Energy Saving (NES) can simultaneously reduce carbon emissions and save operating costs, which is of great significance to environmental sustainability.

[0003] However, to adapt to various scenarios of 5G-Advanced and 6G MIMO, a unified and flexible NES solution needs to be designed.

The port group is a portion of the antenna port group of the antenna panel associated with one or more CSI-RS resources in the CSI-RS resource set. The horizontal and vertical dimension information of the port group is... Based on the port group, the antenna panel is uniformly divided into A group of antenna ports; the bitmap is a set bitmap of the port groups. The value can be 2, 3, 4, 6, 8, 12 or 16.

[0009] Preferably, the CSI report ID set information includes L1 CSI report IDs, and the CSI sub-report ID set information includes L2 CSI sub-report IDs; each CSI report ID and CSI sub-report ID is used to identify a CSI report and a CSI sub-report, respectively, and L1 and L2 are positive integers; the CSI report energy-saving mode information includes: Energy-saving mode: Only submit energy-saving reports; Combined mode: Submit regular non-energy-saving CSI reports and energy-saving reports; Adaptive mode: Report a regular non-energy-saving CSI report or report an energy-saving report; Among them, the energy-saving report is either an energy-saving CSI report or an energy-saving CSI sub-report. Each energy-saving CSI report and each energy-saving CSI sub-report represent a CSI report and a CSI sub-report, respectively, for an energy-saving solution. The conventional non-energy-saving CSI report represents a CSI report for a conventional non-energy-saving solution.

[0015] This invention offers the following advantages: It uniformly divides the antenna panel into antenna subgroups, directly indicating the activation status of each subgroup through a resource set bitmap or a port group set bitmap. This method replaces the traditional port-by-port independent indication method, significantly reducing the activation and deactivation signaling interaction during switching between energy-saving and non-energy-saving modes, solving the problem of excessive signaling overhead in existing technologies, and adapting to the high-speed signaling transmission requirements of 5G / 6G-MIMO massive MIMO antenna scenarios. This invention supports two indication methods: CSI-RS resource set bitmap and port group set bitmap, compatible with different antenna array sizes, port numbers, and subarray partitioning structures, and adaptable to various antenna technologies. Based on the uniform horizontal and vertical dimensions of a uniform area array (UPA), this invention uniformly divides antenna subgroups, enabling rapid port-level switching and overall subarray-level start / stop, precisely controlling the operating status of high-energy-consuming modules such as power amplifiers (PAs). Under different service scenarios such as no-load, low-load, and full-load, it maximizes the reduction of AAU energy consumption, balancing communication performance and energy-saving benefits. This invention also divides CSI reports into regular non-energy-saving CSI reports and energy-saving reports / sub-reports, providing three reporting modes: energy-saving, combined, and adaptive. Reporting content can be selected as needed, reducing the amount of terminal measurement and feedback calculations. In this way, a balance is achieved between performance and energy consumption by flexibly reporting energy-saving or non-energy-saving CSI reports. At the same time, it supports three triggering methods: non-periodic, semi-continuous, and periodic. There is no need to reconstruct the communication protocol, resulting in low implementation cost and strong scalability. Attached Figure Description

Detailed Implementation

[0017] The following detailed description of the embodiments, in conjunction with the accompanying drawings, will further illustrate the specific implementation of the present invention, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of the present invention.

[0018] Extreme Massive Multiple-Input Multiple-Output (X-MIMO) and Giga Massive Multiple-Input Multiple-Output (Giga-MIMO) have garnered significant attention as potential key technologies in the B5G / 6G multi-antenna field. The core characteristic of X-MIMO is that, while maintaining an antenna aperture comparable to that of New Radio (NR), it deploys denser antenna arrays in the mid-frequency band (7-13GHz), achieving 256 or 512 antenna ports. While X-MIMO can significantly improve communication speeds and enhance multi-user multiplexing capabilities, it also leads to a significant increase in operating costs and energy consumption.

[0019] To improve the effectiveness and reliability of communication systems, 3GPP has gradually enhanced the transmission capabilities in MTRP scenarios: Rel-16 initiated related enhancement work, and has already supported two types of schemes: SDCI (adapted to ideal backhaul) and MDCI (adapted to ideal / non-ideal backhaul); Rel-17 completed the enhancement of CSI (channel state information) measurement and reporting for non-coherent joint transmission (NCJT); and Rel-18 designed a coherent joint transmission (CJT) codebook and optimized CSI reporting based on eType-II and FeType-II codebooks to improve the system capacity and coverage of ideal backhaul and synchronous commercial scenarios.

[0020] In NR, the Channel State Information Reference Signal (CSI-RS) is used for downlink CSI measurement and feedback. The complete process on the UE side is: receiving CSI-RS configuration information → sending CSI-RS based on the configuration measurement BS → feeding back downlink CSI reports based on the measurement results. To improve flexibility, NR divides the CSI framework into two parts: Resource Setting and Reporting Setting, specifically defined as follows: 1. CSI Resource Setting: Determined by the Radio Resource Control (RRC) Information Element (IE) CSI-ResourceConfig. Each CSI-ResourceConfig contains at least one NZP-CSI-RS-ResourceSet, and / or CSI-IM-ResourceSet, and / or CSI-SSB-ResourceSet; wherein, the NZP-CSI-RS-ResourceSet contains at least one NZP-CSI-RS-Resource (which can be used for channel / interference measurement), and the CSI-IM-ResourceSet contains at least one CSI-IM-Resource (used only for interference measurement). Hereafter, both will be collectively referred to as CSI-RS Resources, which can be classified into three types according to their time-domain characteristics: periodic, semi-persistent, and aperiodic. The transmission of semi-persistent and aperiodic CSI-RS is triggered by Downlink Control Information (DCI).

[0021] 2. Reporting Setting: Determined by the RRC IE CSI-Reportconfig, each CSI-Reportconfig is associated with at least one CSI-ResourceConfig, containing information such as the corresponding channel / interference measurement resources, report type, quality, frequency domain configuration, and codebook configuration. Reports are categorized into three types: periodic CSI reports (no dynamic triggering / activation required, carried on the Physical Uplink Control Channel (PUCCH)); semi-persistent CSI reports (can be carried on PUCCH / Physical Uplink Share Channel (PUSCH), the former activated by the Medium Access Control Control Element (MAC-CE), the latter triggered by the DCI); and aperiodic CSI reports (carried on PUSCH, triggered by the DCI). NR further clarifies the association rules between CSI measurement resources and reports: periodic CSI-RS supports all three report types, semi-persistent CSI-RS supports semi-persistent / aperiodic reports, and aperiodic CSI-RS only supports aperiodic reports.

[0022] 3GPP-Rel-18 has completed the Spatial Domain Adaptations (SDA) NES scheme for centralized BS, including two core schemes: Type-I-SDA (disabling all antenna elements in a subarray and changing the number of logical antenna ports); and Type-II-SDA (disabling some antenna elements in a subarray, without changing the number of logical antenna ports but adjusting the beamform). To minimize the impact of standardization, this scheme reuses the existing CSI measurement and reporting framework, configuring multiple sub-configurations through a single CSI report-config, with each sub-configuration associated with a sub-CSI-report, corresponding to a set of SDA patterns and CSI-RS resources. The specific process is as follows: the UE measures the multiple sets of CSI-RS configured by the BS and reports the results; the BS selects the SDA pattern based on the results; among them, Type-I-SDA uses a bitmap to indicate the active antenna ports of different sub-configurations ("1" for active, "0" for silent).

[0023] To address key issues such as port-level fast switching information indication and CSI report measurement configuration in energy-saving and non-energy-saving states, and to avoid the problem of excessive signaling overhead caused by the direct use of bitmap indication in existing technologies, this invention provides a measurement resource and measurement report configuration method for energy saving.

[0024] like Figures 1-2 As shown, the method for configuring measurement resources and measurement reports for energy conservation includes: The user equipment receives the instruction information, performs CSI measurement based on the received instruction information, determines the CSI report according to any one of the methods of CSI report energy saving mode information and sends it; the CSI report energy saving mode information includes reporting only the CSI report indicating the energy saving scheme, reporting both the energy saving scheme and the conventional non-energy saving scheme simultaneously, and adaptively selecting the CSI report to be reported from the CSI reports indicating the energy saving scheme and the conventional non-energy saving scheme.

[0025] Correspondingly, on the network access device side, the network access device first sends indication information to the user equipment, and then receives the CSI report from the user equipment.

[0026] This method, when saving energy in the spatial domain, uniformly divides the antenna panel of a Uniform Planar Array (UPA) into identical antenna sub-groups or subarrays; by deactivating or activating one or more antenna sub-groups as a whole, it flexibly achieves the shutdown or opening of some antenna ports. The antenna panel is uniformly divided into antenna sub-groups based on the horizontal and vertical dimensions of the antenna.

[0027] An example of antenna subgroup division is as follows: Assume a UPA (Uniform Area Array) uses dual-polarized antennas, and the horizontal and vertical dimensions of the initial antenna (the entire antenna panel) are N1 and N2, respectively, while the horizontal and vertical dimensions of the antenna subgroups are N1' and N2', respectively. Then, the number of antenna ports P of the initial UPA and the number of antenna subgroup ports P' are 2. N1 N2 and 2 N1' N2'. Number of antenna subgroups =P / P'=N1 N2 / (N1' N2'). The indices of the antenna subgroups increase sequentially, first horizontally and then vertically. The antenna port indices of both the UPA and the antenna subgroups increase sequentially, first by polarization, then horizontally, and finally vertically. The antenna port indices of the UPA and the antenna subgroups start from 0. The indices of the antenna subgroups start from 1.

[0028] Based on the above antenna subgroup division method, the corresponding switching information indication method is as follows: Resource bitmap-based: This method directly indicates whether the antenna subgroup of the UPA is active through a bitmap. The length of the bitmap is... In the Bitmap, a value of 1 in the i-th bit indicates activation of the i-th antenna subgroup, and a value of 1 in the j-th bit indicates activation of the j-th antenna subgroup. Here, i and j are values ​​from 1 to... Positive integers between.

[0043] This invention provides three measurement reporting modes, corresponding to the following CSI report energy-saving mode information: A. NES-Mode-A: This parameter indicates that the CSI report or CSI sub-report is in energy-saving mode. In energy-saving mode, only one energy-saving CSI report or CSI sub-report is reported.

[0044] B. NES-Mode-B: This parameter indicates that the CSI report or CSI sub-report mode is a combined mode. In combined mode, an energy-saving CSI report or CSI sub-report plus a regular non-energy-saving CSI report needs to be submitted.

[0045] C, NES-Mode-C: This parameter indicates that the CSI reporting mode is adaptive. In adaptive mode, you need to choose between an energy-saving CSI report or CSI sub-report and a regular non-energy-saving CSI report for submission.

[0046] The energy-saving CSI report refers to the CSI report of the antenna array under energy-saving status (partial deactivated antenna array). The energy-saving CSI report contains several energy-saving CSI sub-reports, each corresponding to an energy-saving scheme (corresponding to specific activation and deactivation bitmap information). The regular non-energy-saving CSI report refers to the CSI report of the antenna array under the regular status (all antenna arrays are activated) without energy saving.

[0047] Based on the above-mentioned antenna subgroup division, bitmap indication information, resource configuration division, and port group division, the configuration method provided by this invention, specifically the transmission and reception process of the measurement report, is as follows: The BS (base station, i.e., access network equipment) sends the first indication information and the second indication information. The UE (User Equipment) receives the first indication information and the second indication information; The UE performs CSI measurements based on the first indication information and the second indication information; The UE sends a CSI measurement report to the BS; BS receives CSI measurement reports.

Each CSI report ID and each CSI sub-report ID is used to identify a CSI report and a CSI sub-report, respectively. Both CSI report IDs and CSI sub-report IDs are non-negative integers. L1 and L2 are both positive integers.

[0050] The CSI-RS resource set information includes One CRI, The values ​​are 2, 3, 4, 6, 8, 12, and 16. Each CRI indicates a CSI-RS resource.

[0051] The CSI-RS resource set bitmap indicator information has a length of The sequence of bits, from high to low, is associated with each CRI in the CSI-RS resource set information. A value of 1 or 0 in the sequence indicates that all logical antenna ports associated with the CSI-RS resource indicated by that CRI are turned on (activated) or off (deactivated).

[0052] The port group is a partial antenna port group of a UPA associated with one or more CSI-RS resources in the CSI-RS resource set information. The horizontal and vertical dimension information of the UPA associated with one or more CSI-RS resources in the CSI-RS resource set is (N1, N2). The horizontal and vertical dimension information of the port group is (N1, N2). The UPA can be evenly divided into... One antenna port group. The values ​​are 2, 3, 4, 6, 8, 12, and 16.

[0053] The port group set bitmap indication information is as follows: The sequence of bits, from high to low, is associated with one or more antenna port groups of a UPA associated with a CSI-RS resource. A value of 1 or 0 in this sequence indicates that all logical antenna ports associated with that port group are enabled or disabled.

[0054] The energy-saving mode information in the CSI report is used to indicate the type of the reported CSI report or CSI sub-report, including energy-saving mode, combined mode, and adaptive mode.

[0055] The power offset information represents the power offset of the CSI-RS RE (Resource Unit of Channel State Information Reference Signal) under the energy-saving CSI sub-report or CSI report relative to the PDSCH RE (Resource Unit of Physical Downlink Shared Channel), and its value is an integer between 0 and 23.

[0056] In the above process, the second instruction information report shall include at least one of the following elements: Non-periodic triggering state set information; Semi-persistent trigger state set information; Information on the set of control elements in the media access control layer; CSI report ID set selection information; CSI Sub-Report ID Set Selection Information.

[0057] The non-periodic trigger state set information includes L3 non-periodic trigger states; the media access control layer control element set information includes L4 media access control layer control elements that trigger semi-persistent CSI; the semi-persistent trigger state set information includes L5 semi-persistent trigger states; and the CSI report ID set selection information and CSI sub-report ID set selection information are bitmap signaling of lengths L1 and L2, respectively. A bit in the bitmap being 1 indicates that the CSI report or CSI sub-report is selected.

[0058] Each non-periodic triggered state is associated with at least one of the following: A non-periodic CSI report; A non-periodic CSI sub-report; Multiple non-periodic CSI sub-reports.

[0059] Each semi-persistent triggered state is associated with at least one of the following: A semi-continuous CSI report; A semi-continuous CSI sub-report; Multiple semi-continuous CSI sub-reports.

[0060] Each media access control layer control element must be associated with at least one of the following: A semi-continuous CSI report; A semi-continuous CSI sub-report; Multiple semi-continuous CSI sub-reports.

[0061] Based on the aforementioned measurement report transmission and reception process and the information contained in the reports, the measurement report configuration method of the present invention includes the following two embodiments. The corresponding measurement report configuration components are as follows: The first embodiment is based on CSI subreports. In this embodiment, CSI-subreport-configID (CSI subreport ID) is used to distinguish different energy-saving schemes; that is, CSI subreport represents the corresponding energy-saving scheme, and CSI-report-configID (CSI report ID) represents the regular non-energy-saving scheme. The CSI subreport ID is included in the CSI report configuration information.

[0062] The second embodiment is based on CSI reports. In this embodiment, CSI-report-configID (CSI report ID) is used to represent both non-energy-saving schemes (i.e., conventional schemes) and to distinguish different energy-saving schemes.

[0063] The following is an example of how to configure the specific measurement report in the above embodiments: First embodiment: Example 1 – CSI report configuration using power-saving mode and based on CSI-RS resource set bitmap indication information: Configure only one CSI-reportconfig (CSI report configuration information), and within this CSI-reportconfig, configure L CSI-reportSubconfigs (CSI sub-report configuration information). Each CSI-reportconfig is associated with one CSI report, which includes L CSI sub-reports. Each CSI-reportSubconfig is associated with one CSI sub-report, and each CSI sub-report corresponds to one energy-saving scheme. Here, L is a positive integer. It is possible to report L CSI sub-reports.

[0064] The CSI-reportconfig must include at least one of the following elements: CSI Report ID; CSI-RS resource collection information; Report configuration type; Report the quality type; Information on the horizontal and vertical dimensions of the antenna panel; CSI reports information on energy-saving modes; The CSI report ID is used to represent a CSI report, and the CSI report ID value is a non-negative integer.

[0065] CSI-RS resource collection information includes One CRI, The values ​​are 2, 3, 4, 6, 8, 12, and 16. Each CRI indicates a CSI-RS resource.

[0066] The report configuration type is used to determine the periodicity, carrying method, and time domain parameter configuration of CSI reports, including non-periodic reports, semi-persistent reports carried on PUSCH, semi-persistent reports carried on PUCCH, and periodic reports.

[0067] The horizontal and vertical dimension information of the antenna panel refers to the horizontal and vertical dimension information of the UPA associated with one or more CSI-RS resources in the CSI-RS resource set, and its value is (N1, N2).

[0068] The reported quality types include 'cri-RI-i1-CQI', 'cri-RI-CQI', and 'cri-RI-i1'.

[0069] The CSI report indicates that the energy-saving mode information is NES-Mode-A (energy-saving mode).

[0070] Each CSI-reportSubConfig must contain at least one of the following elements: CSI Sub-Report ID; Codebook type; CSI-RS Resource Set Bitmap Indicator Information; Power offset information.

[0071] The CSI subreport ID is used to identify a CSI subreport, and the CSI subreport ID is a non-negative integer.

[0072] CSI-RS resource collection bitmap indication information is of length [missing information]. The sequence of bits, from high to low, is associated with each CRI in the CSI-RS resource set. A value of 1 or 0 in this sequence indicates that all logical antenna ports associated with the CSI-RS resource indicated by that CRI are enabled or disabled.

[0073] The codebook type can be 'TypeI-SinglePanel', 'TypeII', or 'eTypeII'.

[0074] The power offset information indicates the power offset of the CSI-RS RE relative to the PDSCH RE in the energy-saving CSI sub-report or CSI report, and its value is an integer between 0 and 23.
