Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, specifically to a method and apparatus for supercell scheduling under mixed antenna configurations. Additionally, it relates to an electronic device and a processor-readable storage medium. Background Technology

[0002] In recent years, with the rapid development of internet technology, services enabled by wireless network communication technology have become increasingly widespread. 5G (5th Generation Mobile Communication Technology), as the fifth generation of mobile communication networks, boasts faster peak transmission speeds and a better user experience than 4G networks. Currently, supercells with mixed antenna configurations in 5G systems are being widely researched and gradually rolled out to commercial networks. A supercell consists of multiple CPs (Cell Portions), each sharing the supercell's resources, including PCI (Physical-layer cell identities), time-domain resources, and frequency-domain resources. Supercells can eliminate interference between internal CPs and convert interference into useful signals, improving the SINR (Signal to Interference plus Noise Ratio) in the overlapping CP area, thereby increasing the throughput of UEs (User Equipment) in the overlapping area. UEs can move between CPs within a supercell without handover, thus reducing service interruptions or decreased user throughput caused by frequent handovers. Therefore, supercells are widely used in indoor distributed systems and scenarios sensitive to handover and inter-cell interference, such as high-speed rail.

[0003] However, in actual network deployments, it's common to encounter scenarios where a single-channel network (CP) within a supercell has two different antenna configurations and supports different numbers of transmit antenna ports. For example, some CPs within a supercell might have M antennas supporting PM downlink transmissions, while others might have N antennas supporting PN downlink transmissions. Terminals cannot recognize this situation. Current network equipment often only configures one set of periodic CSI-RS (Channel-state information reference signal) for UE measurement feedback, used for CQI (Channel Quality Indicator), PMI (Pre-coding Matrix Indicator), and RI (Rank Indicator) measurement feedback. This measurement feedback corresponds to only one antenna configuration scenario, causing the RI reported by the terminal to potentially mismatch the number of transmit antenna ports supported by its CP, resulting in lost UE traffic during scheduling. For example, if the configured number of CSI-RS ports is equal to the smaller of PM and PN, the RI reported by the UE will be limited by the smaller of PM and PN, potentially causing a loss of UE layer level during scheduling and thus UE traffic. If the configured number of CSI-RS ports is equal to the larger of PM and PN, and the UE is within the CP coverage area of ​​the smaller of PM and PN, the reported RI may be greater than the smaller of PM and PN. In this case, the reported value obtained by the network device will be inaccurate, and the network device cannot accurately schedule based on the UE's report, resulting in a loss of UE traffic. Therefore, how to make adaptive configurations in supercells with mixed antenna configurations and design a stable and efficient scheduling scheme to solve the problem of UE-side measurement reporting in this scenario has become an important research topic for those skilled in the art. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] The present invention proposes a super cell scheduling method under mixed antenna configuration. By configuring two sets of periodic channel state reference signal measurement configuration information, two sets of periodic reporting by user equipment are satisfied, so that in a super cell with mixed antenna configuration, the network equipment side (i.e., the base station side) can obtain accurate channel state information according to the position of the user equipment, so as to perform optimal scheduling to improve cell throughput. At the same time, according to the precoding matrix indicator reported by the user equipment, the present invention selects a reasonable weight in the super cell for single regular cell transmission or joint data transmission of multiple regular cells, and maximizes the throughput of the super cell with mixed antenna configuration through effective selection of the precoding matrix indicator.

[0043] In the following, the embodiments are described in detail based on the super cell scheduling method under mixed antenna configuration according to the present invention. As Figure 1 shown, it is one of the schematic flow diagrams of the super cell scheduling method under mixed antenna configuration provided in the embodiment of the present invention, and the specific implementation process includes the following steps:

[0044] Step 101: Determine the corresponding first set of channel state reference signal measurement configuration information and the second set of channel state reference signal measurement configuration information respectively based on the difference between the antenna configuration information corresponding to the regular cells included in the super cell and the number of supported transmit antenna ports.

[0045] The embodiment of the present invention is applied to the super cell scheduling scheme under mixed antenna configuration, and the super cell includes K CP (Cell-Portion, regular cell). The K CPs are divided into two types: one type includes M antennas, and the maximum number of configurable CSI-RS (Channel-state information reference signal, channel state reference signal measurement configuration information) ports is PM; the other type includes N antennas, and the maximum number of configurable CSI-RS ports is PN. Wherein, PN=N<M=PM, and PN, N, M, PM, K are all integers.

[0046] In the specific implementation process, after the UE (User Equipment) accesses the supercell, it first configures a set of CSI-RS with PM ports (referred to as the first set of CSI-RS, i.e., the first set of Channel State Reference Signal Measurement Configuration Information) based on the antenna configuration information and the number of supported transmit antenna ports of the regular cells contained in the supercell. It also configures a set of CSI-RS with PN ports (referred to as the second set of CSI-RS, i.e., the second set of Channel State Reference Signal Measurement Configuration Information). Both sets of CSI-RS are used by the user equipment to periodically feed back PMI (Pre-coding Matrix Indicator), RI (Rank Indicator), and CQI (Channel Quality Indicator) measurement configuration information to the network equipment.

[0047] Step 102: Based on the first set of channel state reference signal measurement configuration information and the number of transmit antenna ports supported by the conventional cell, send the corresponding first channel state reference signal measurement configuration information to the user equipment; and based on the second set of channel state reference signal measurement configuration information and the number of transmit antenna ports supported by the conventional cell, send the corresponding second channel state reference signal measurement configuration information to the user equipment.

[0048] In this embodiment of the invention, the network device can send corresponding first channel state reference signal measurement configuration information to the user equipment based on the first set of channel state reference signal measurement configuration information and the number of transmit antenna ports supported by the conventional cell; and send corresponding second channel state reference signal measurement configuration information to the user equipment based on the second set of channel state reference signal measurement configuration information and the number of transmit antenna ports supported by the conventional cell. In specific implementation, the same first channel state reference signal measurement configuration information for M ports is sent on the CPs of M antennas based on the first set of CSI-RS; the first channel state reference signal measurement configuration information for N ports is extracted and sent on the CPs of N antennas; the same second channel state reference signal measurement configuration information for PN ports is sent on the CPs of M antennas based on the second set of CSI-RS; and the same second channel state reference signal measurement configuration information for PN ports is sent on the CPs of N antennas.

[0049] Step 103: If the user equipment's home cell corresponds to the first type of antenna configuration information, then downlink channel scheduling is performed based on the channel state information measured and reported by the user equipment according to the first channel state reference signal measurement configuration information; if the user equipment's home cell corresponds to the second type of antenna configuration information, then downlink channel scheduling is performed based on the channel state information measured and reported by the user equipment according to the second channel state reference signal measurement configuration information; wherein, the antenna configuration information includes the first type of antenna configuration information and the second type of antenna configuration information.

[0050] In this embodiment of the invention, after receiving multiple channel state reference signal measurement configuration information, the user equipment can simultaneously calculate channel state information (CSI) based on the multiple channel state reference signal measurement configuration information. The channel state information CSI includes PMI, RI, and CQI.

[0051] In this step, the network device receives the corresponding Channel State Information (CSI) reported by the user equipment. The CSI is data that can be measured by CSI-RS. The Channel State Reference Signal Measurement Configuration Information includes first and / or second channel state reference signal measurement configuration information. Downlink PDSCH (Physical Downlink Shared Channel) scheduling is performed based on the CQI, PMI, and RI reported by the UE according to the first set of CSI-RS measurements. If the number of home CP antennas of the UE is N, the network device performs downlink PDSCH scheduling based on the CQI, PMI, and RI reported by the UE according to the second set of CSI-RS measurements.

[0052] In one signal transmission process, if the user equipment (UE) uses its home regular cell for signal transmission, the first precoding indication reported based on the channel state reference signal measurement configuration information corresponding to the current home regular cell is determined as the first weight, and signal transmission is performed based on the first weight; wherein, the channel state reference signal measurement configuration information is either the first channel state reference signal measurement configuration information or the second channel state reference signal measurement configuration information. Specifically, if the supercell uses the UE's home CP for transmission, the PMI reported based on the CSI-RS measurement configuration corresponding to the current home CP is determined as the first weight, and signal transmission is performed based on this first weight.

[0053] In addition, during another signal transmission process, after the user equipment (UE) accesses the supercell, it periodically determines the active regular cells of the UE and identifies an active set containing at least two of these active regular cells. The active regular cells are regular cells whose downlink received signal strength meets a preset threshold. The active regular cells include the home regular cell. If at least two active regular cells within the active set are used for joint transmission, a corresponding second precoding indication is determined for each active regular cell in the active set based on the UE's current home regular cell and the rank indication reported by the UE. The signal is transmitted based on the second precoding indication as a second weight. The home regular cell is the active regular cell with the highest downlink received signal strength of the UE. The channel state information includes a precoding indication, a rank indication, and a channel quality indication.

[0054] Specifically, the network equipment periodically determines the UE's active CP (Activated CP), i.e., activates a regular cell. Based on the aforementioned measurement configuration information, it periodically measures the first and second sets of CSI-RS, and obtains the corresponding CQI, PMI, and RI fed back by the user equipment side. If the number of antennas belonging to the UE's home CP is M, the network equipment performs downlink PDSCH scheduling based on the CQI, PMI, and RI reported by the UE according to the first set of CSI-RS measurements. If the number of antennas belonging to the UE's home CP is N, the base station performs downlink PDSCH scheduling based on the CQI, PMI, and RI reported by the UE according to the second set of CSI-RS measurements. During scheduling, if the super cell uses the UE's home CP for transmission, the PMI reported based on the corresponding CSI-RS configuration is selected as the first weight, and signal transmission is performed based on the first weight. If the super cell uses multiple CPs within the active set for joint transmission, the PMI is determined for each CP within the active set based on the UE's current home CP and the RI reported by the UE, and the determined PMI is used as the second weight. The CP then transmits signals based on the second weight.

[0055] In a complete implementation scenario, K adjacent cells need to be pre-assembled into a supercell. A cell within a supercell is called a CP (Content Processing Unit). The value of K can be chosen based on hardware capabilities, computational complexity, etc. There are two different numbers of antennas for a CP that makes up a supercell: some CPs have M antennas, and some have N antennas, with M assumed to be greater than N. If only one PCI (Personalized Interchange Interface) is configured for a supercell, the UE (User Equipment) can only see the supercell and not the K CPs within it.

[0056] In this embodiment of the invention, after a UE accesses a super cell, a CSI-RS is configured for feeding back CQI, PMI, and RI measurements. Assuming the maximum configurable number of CSI-RS ports for a CP with M antennas is PM, and the maximum configurable number of CSI-RS ports for a CP with N antennas is PN, where CSI-RS refers to the first set of channel state reference signal measurement configuration information and / or the second set of channel state reference signal measurement configuration information required for the UE to measure CQI, PMI, and RI. The relationship between M, N, PM, and PN in this application is as follows:

[0057] PN = N < PM ≤ M

[0058] A set of CSI-RS with PM ports is configured for the UE, referred to as the first set of CSI-RS (first set of channel state reference signal measurement configuration information). A set of CSI-RS with PN ports is configured, referred to as the second set of CSI-RS (second set of channel state reference signal measurement configuration information). Both sets of CSI-RS serve as measurement CSI-RS for periodic feedback CQI, PMI, and RI. The methods for transmitting the corresponding first and second channel state reference signal measurement configuration information are as follows:

[0059] 1) The first CSI-RS transmits the same first channel state reference signal measurement configuration information of M ports on the CP of M antennas. The first channel state reference signal measurement configuration information of N ports is extracted from the CP of N antennas and transmitted. The N ports can be selected.

[0060] 2) The second set of CSI-RS transmits the same second set of channel state reference signal measurement configuration information with PN ports on the CP of M antennas, and transmits the same second set of channel state reference signal measurement configuration information with PN ports on the CP of N antennas.

[0061] Meanwhile, after a UE accesses a super cell, the network equipment can periodically determine the UE's active CP. An active CP is a CP whose downlink received signal strength meets a preset threshold. A UE can have multiple active CPs, and the CP with the strongest downlink received signal strength is defined as the UE's home CP.

[0062] Furthermore, the UE periodically measures the first and second sets of CSI-RS and feeds back the corresponding CQI, PMI and RI respectively.

[0063] If the number of home CP antennas of the UE is M, the network device performs downlink PDSCH scheduling based on the CQI, PMI and RI reported by the UE according to the first set of CSI-RS measurements. If the number of home CP antennas of the UE is N, the network device performs downlink PDSCH scheduling based on the CQI, PMI and RI reported by the UE according to the second set of CSI-RS measurements.

[0064] It should be noted that in a supercell, if the UE's home CP is used for transmission, the UE's home CP can be transmitted using the reported PMI as the weight. That is, for a CP with M antennas, the PMI fed back from the first set of CSI-RS is used as the weight; for a CP with N antennas, the PMI fed back from the second set of CSI-RS is used as the weight. If joint transmission of CPs within the active set is used, the following processing applies:

[0065] 1) If the number of antennas of the UE’s home CP is N, then for the CPs of PN ports in the active set, the PMI reported by the second set of CSI-RS is used for transmission. For the CPs of PM ports in the active set with the number of antennas M, the PMI reported by the second set of CSI-RS is also used for transmission. Alternatively, the PMI reported by the first set of CSI-RS can be used for transmission. However, it is necessary to ensure that the RI corresponding to the PMI reported by the UE according to the first set of CSI-RS is equal to the RI of the current scheduling, and that the PMI is within a certain time range. The time range refers to the time from when the UE reports the PMI to the current scheduling time being less than a certain time. The length of this time can be determined according to the UE’s moving speed, channel changes, etc.

[0066] 2) If the number of antennas of the UE’s home CP is M, and the RI reported by the UE is less than or equal to PN, then for the CPs of PM ports in the active set, the PMI reported by the first set of CSI-RS is used for transmission. For the CPs of PN ports in the active set with the number of antennas N, the PMI reported by the second set of CSI-RS can be used for transmission. However, it is necessary to ensure that the RI corresponding to the PMI reported by the second set of CSI-RS is equal to the RI of the current scheduling, and that the PMI is within a certain time range. Alternatively, the PMI of N ports can be extracted from the PMI reported by the first set of CSI-RS as weights for transmission. The extracted N ports are the same as the PN port numbers corresponding to the transmission of the second set of CSI-RS in step 2.

[0067] 3) If the number of antennas of the UE’s home CP is M, and the RI reported by the UE is greater than PN, then for the CP of PM ports in the active set, the PMI reported by the first set of CSI-RS is used for transmission. For the CP of PN ports in the active set, the number of antennas is N. N ports and the PMI of the RI layer can be extracted from the PMI reported by the first set of CSI-RS as weights for transmission. The N ports extracted are the same as the PN ports corresponding to the transmission of the second set of CSI-RS in step 2. The extracted layer number can be the previous RI layer, or other layers can be selected. A total of RI layers can be extracted. Alternatively, the latest PMI reported by the second set of CSI-RS can be used to transmit only the corresponding reported RI layer.

[0068] In a specific implementation process, the scheduling method for supercells under antenna mixing in a 5G system includes the following:

[0069] Two adjacent cells are grouped into a supercell, denoted as CP1 and CP2, and the resulting supercell is called Cell1. CP1 has 4 antennas, and CP2 has 2 antennas. Cell1 is configured with PCI so that the UE can only see Cell1 and obtain its PCI, but cannot see CP1 and CP2 within Cell1. After the UE accesses Cell1, it is configured with CSI-RS for CQI, PMI, and RI measurement feedback. CP1 has a maximum configurable number of CSI-RS ports of 4, and CP2 has a maximum configurable number of CSI-RS ports of 2. CSI-RS refers to the CSI-RS required for UE-side CQI, PMI, and RI measurements. A set of 4-port CSI-RS configured for the UE is called the first set of CSI-RS, and a set of 2-port CSI-RS is called the second set of CSI-RS. Both sets of CSI-RS serve as periodic feedback CQI, PMI, and RI measurement CSI-RS. The CSI-RS transmission method is as follows:

[0070] 1) The first set of CSI-RS transmits CSI-RS on CP1 with 4 ports, and extracts the CSI-RS of the first 2 ports on CP2 for transmission.

[0071] 2) The second set of CSI-RS sends the same two ports of CSI-RS on both CP1 and CP2.

[0072] Cell1 periodically determines the UE's active CP during the access process and normal service after access. Assuming the CP with the strongest received signal strength from the UE is CP2, then CP2 is the UE's home CP. Based on the above measurement configuration information, the UE periodically measures the first and second sets of CSI-RS and reports the corresponding CQI, PMI, and RI respectively. The base station performs downlink PDSCH (Physical Downlink Shared Channel) scheduling based on the CQI, PMI, and RI reported by the second set of CSI-RS. In a supercell, the UE's home CP is used for transmission; therefore, CP2 can be transmitted using the PMI from the second set of CSI-RS reported in step 5 as a weight.

[0073] In addition, in another specific implementation process, Cell1 periodically determines the UE's active CP during the access process and normal service after access. Assuming the CP with the strongest received signal strength from the UE is CP1, then CP1 is the UE's home CP. Furthermore, if the power received by the UE from CP2 also meets a certain threshold, then the UE simultaneously activates CP2. Based on the above measurement configuration information, the UE periodically measures the first and second sets of CSI-RS and feeds back the corresponding CQI, PMI, and RI. The base station performs downlink PDSCH (Physical Downlink Shared Channel) scheduling based on the CQI, PMI, and RI reported by the first set of CSI-RS measurements.

[0074] In a supercell, joint transmission of CPs within the active set is used: If the RI reported by the UE is less than or equal to 2, then for CP1, the PMI reported by the first set of CSI-RS is used for transmission; for CP2, the PMI reported by the second set of CSI-RS can be used. However, it is necessary to ensure that the RI corresponding to the PMI reported by the second set of CSI-RS is equal to the currently scheduled RI, and that the PMI is within a certain time frame. Alternatively, the PMI of the first two ports can be extracted from the PMI reported by the first set of CSI-RS as weights for transmission. If the RI reported by the UE is greater than 2, then for CP1, the PMI reported by the first set of CSI-RS is used for transmission; for CP2, the PMI of the first two ports and the first two layers are extracted from the PMI reported by the first set of CSI-RS as weights for transmission.

[0075] The supercell scheduling method under mixed antenna configuration described in this embodiment of the invention utilizes multiple sets of periodic channel state reference signal measurement configuration information to enable user equipment to periodically report channel state information. This allows the network equipment to obtain accurate channel state information based on the location of the user equipment for optimal scheduling, thereby improving the throughput of the supercell with mixed antenna configuration.
