Abstract
Description
Information processing method, apparatus, and communication system TECHNICAL FIELD
[0001] Embodiments of the present application relate to the field of communication technology. BACKGROUND
[0002] With the popularity of the fifth generation (5G) communication network in various industries and its application in more geographical areas, in order to provide more advanced services, very high data rates and more intensive networks are required. More number of antennas, larger dimension antenna arrays are currently considered for use on the 5G base station side. In the extended new frequency bands that can be used, larger dimension antenna arrays can enhance beam coverage and also serve more user data needs.
[0003] However, due to the use of more number of antennas, larger bandwidth and more frequency bands, the energy consumption of 5G devices becomes larger and larger. According to the data statistics of operators, the average energy consumption of a 5G base station is more than three times that of an LTE (Long Term Evolution) base station. Operators have nearly 50% of the cost of deploying a 5G network in electricity expenses. More importantly, even in the time period without business, the energy consumption of 5G base station is still very large. Therefore, network energy saving is of great significance to improve the sustainability of the environment, reduce the impact on the environment (such as reducing greenhouse gas emissions), and save operating costs. 5G network energy saving is a problem to be solved.
[0004] In order to achieve network energy saving, 5G has initiated network energy saving related issues to study various energy saving technologies. In the discussion, network energy saving technologies can be divided into time domain / frequency domain / space domain / energy domain energy saving, etc. Space domain energy saving, for example, is dynamic adjustment of the number of antennas. Specifically, it can be divided into two space domain energy saving scenarios, including closing / opening digital antenna ports under energy saving optimization, and closing / opening physical antennas under energy saving optimization, etc.
[0005] It should be noted that the above introduction to the technical background is only to facilitate a clear and complete description of the technical solutions of the present application, and to facilitate the understanding of those skilled in the art.

[0052] The following describes the scenarios of the embodiments of the present application by way of examples, but the present application is not limited thereto.
[0053] FIG. 1 is a schematic diagram of a communication system according to an embodiment of the present application, which schematically illustrates a case taking a terminal equipment and a network device as an example. As shown in FIG. 1, the communication system 100 can include a network device 101 and terminal equipments 102 and 103. For simplicity, FIG. 1 only takes two terminal equipments and one network device as an example for illustration, but the embodiments of the present application are not limited thereto.
[0054] In the embodiments of the present application, the network device 101 and the terminal devices 102 and 103 can perform existing services or future implementable service transmission. For example, the services can include, but are not limited to, enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.
[0055] It is worth noting that FIG. 1 shows that both terminal devices 102 and 103 are within the coverage of the network device 101, but the present application is not limited thereto. Both terminal devices 102 and 103 can be outside the coverage of the network device 101, or one terminal device 102 is within the coverage of the network device 101 and the other terminal device 103 is outside the coverage of the network device 101.
[0056] In the embodiments of the present application, the higher layer signaling can be, for example, radio resource control (RRC) signaling; for example, referred to as an RRC message, for example, including MIB, system information, dedicated RRC message; or referred to as an RRC IE. The higher layer signaling can also be, for example, MAC (Medium Access Control) signaling; or referred to as a MAC CE. However, the present application is not limited thereto.
[0057] In the embodiments of the present application, in a mobile communication system, a terminal device generally performs channel state information (CSI) measurement according to the indication and configuration of a network device, and reports the measured CSI to the network device. When scheduling the terminal device, the network device can refer to the CSI to schedule the terminal device to transmit in a suitable physical resource and in a suitable transmission mode. Different terminal devices can experience different physical channel conditions, and the CSI feedback mechanism can reasonably and effectively utilize the physical resources, thereby improving the efficiency of the entire network transmission.
[0058] In the CSI feedback mechanism of NR, the terminal device mainly measures and reports the reference signal based on the CSI configuration, including CSI-RS (Channel State Information-Reference Signal) and SSB (Synchronization Signal Block) and the like. The CSI configuration of NR mainly includes two parts: the first part is that the network device configures the reference resource (CSI-RS resource configuration) for the terminal device to measure the CSI; the second part is that the network device configures the terminal device how to report the CSI (CSI reporting configuration).
[0059] For example, in the CSI-RS resource configuration (Resource setting), it can be used for beam management and CSI channel measurement, etc. Each CSI-RS resource configuration contains S resource sets. And each resource set contains Ks CSI-RS resources. The aperiodic resource configuration can contain one or more resource sets. For periodic and semi-persistent resource configurations, only one resource set can be contained for CSI acquisition.
[0060] Among them, the value of Ks is:
[0061] When used for CSI channel measurement, if the codebook type in the reporting setting is ‘Type I’ (which can specifically include CodebookType = ‘TypeISinglePanle’ or ‘TypeIMultiPanle’), Ks <= 32.
[0062] When used for CSI channel measurement, if the codebook type in the reporting setting is ‘Type II’ (which can specifically include CodebookType = ‘typeII’, ‘typeII-PortSelection’, ‘typeII-r16’, ‘typeII-PortSelection-r16’, ‘typeII-PortSelection-r17’), Ks = 1. This is mainly because the calculation complexity of TypeII is relatively large, and the calculation challenge to the terminal device is relatively large, so the NR system limits the value of Ks to relatively reduce the calculation complexity of the terminal device.
[0063] One CSI report consists of two parts (Part 1 and Part 2), where the CSI Part 1 (also referred to as Part 1) has a fixed payload size and indicates the number of information bits of the CSI Part 2 (also referred to as Part 2); in CSI reporting, if the current CSI measurement is for CSI channel measurement, there are also the following reporting content regulations according to different codebook types:
[0064] Type I CSI: part 1 includes RI (Rank Indicator) / CRI (CSI-RS resource index) and the CQI (Channel Quality Indicator) of the first CW (code word); part 2 includes LI (layer indicator) and PMI (Precoding Matrix Indicator), and when the rank is greater than 4, it also includes the CQI of the second CW;
[0065] Type II CSI: part 1 includes RI, CQI and the number of non-zero wideband amplitude coefficients per layer; part 2 includes LI and PMI.
[0066] In Release 15 (R15) - Release 18 (R18), the UE can measure and report CSI based on up to 32 digital ports. In R19, the UE can measure and report CSI based on up to 128 digital ports. Specifically, this can be achieved through the following configurations:
[0067] 1) For CSI-RS resource configuration: 2, 3, 4 CSI-RS resources can be configured within the CSI-RS resource set for channel measurement, which is used to measure 48, 64, 128 port CSI information.
[0068] 2) For CSI reporting configuration: the UE can be configured with one codebook-config for measuring 48, 64, 128 port CSI information. Based on the CSI measurement result, the UE reports one PMI, RI, CQI (1 CQI for 1 CW, 2 CQIs for 2 CWs) based on 48, 64, 128 information, etc.
[0069] FIG. 2 is a schematic diagram of an energy saving scenario according to an embodiment of the present application. As shown in FIG. 2, the network energy saving related space / energy domain element adjustment technology can be divided into two types.
[0070] The left side of FIG. 2 can be referred to as type 1 adjustment, corresponding to energy saving scenario 1. The type 1 adjustment is to enable or disable all antennas (factors) associated with one logical antenna port. In this way, the network device can turn off all antennas (factors) corresponding to one or more antenna ports. Since the total number of antenna ports is reduced, the overall transmission power is reduced without changing the transmission power of each antenna port. The type 1 adjustment directly affects the number of antenna ports.
[0071] The right side of FIG. 2 can be referred to as type 2 adjustment, corresponding to energy saving scenario 2. The type 2 adjustment is to enable or disable part of the antennas (factors) associated with one logical antenna port. In this way, the network device can turn off part of the antennas (factors) corresponding to all antenna ports. Although the total number of antenna ports does not change, the transmission power of each port becomes smaller, and therefore the overall transmission power is reduced. The type 2 adjustment affects the beamforming gain of the network device, and in turn affects the transmission power of the reference signal.
[0072] As shown in FIG. 2, energy saving scenario 1 achieves network energy saving by turning off part of the digital antenna ports. On the terminal device side, after turning off different numbers of antenna ports, the terminal device needs to measure according to different port numbers to generate CSI information under different digital ports. Therefore, the 'nrofports' in the CSI resource configuration and / or N1N2 in the reporting setting may have different values under different energy saving configurations. Therefore, the number of antenna port dimensions in the PMI matrix in the reported CSI is different under different energy saving sub-configurations. The most common for energy saving scenario 1 is to distinguish different antenna port sub-configurations through antenna port indication within one CSI-RS resource, such as different antenna port subsets in the CSI-RS resource can correspond to different antenna port turning off configurations.
[0073] As shown in FIG. 2, in energy saving scenario 2, the TXRU (transceiver unit) / RF antenna number is dynamically adjusted without adjusting the number of digital antenna ports to achieve network energy saving. Therefore, in this case, the 'nrofports' in the CSI resource configuration and / or N1N2 in the reporting setting under different energy saving sub-configurations may not change, and the number of antenna port dimensions in the PMI matrix in the reported CSI does not change, so it can be protocol transparent on the terminal device side. The most common for energy saving scenario 2 is to distinguish different energy saving sub-configurations through different CSI-RS, such as different CSI resources can correspond to different energy saving sub-configurations of the turning off configuration.
[0074] As mentioned above, the version 19 (R19) and more number of antenna port scenarios in the future will have a negative impact on other processes or technologies in the communication system, and cause compatibility problems to the configuration method in the existing standard.
[0075] For example, the CSI (Channel State Information) measurement and reporting feedback in the existing standard is mainly designed to enhance based on a limited number of antenna ports. However, with the increase of the number of antenna ports, the energy consumption of the antenna port transmission data and the reference signal will also increase significantly. Therefore, the optimization and enhancement of the energy saving scenario are imminent.
[0076] In addition, the new enhanced design of the CSI measurement and reporting framework needs to be expanded and enhanced. For example, multiple resource joint configuration is needed to measure the CSI information under multiple antenna ports. Then, for the energy saving scenario, how to optimize the energy saving under the current CSI enhancement framework, for example, how the network device configures multiple antenna configurations, and how the terminal device measures and reports the channel under multiple antenna configurations, are still problems to be solved.
[0077] To solve at least one of the above problems, the embodiments of the present application provide an information processing method, device and communication system.
[0078] Embodiments of the first aspect
[0079] The embodiments of the present application provide an information processing method, which is described from the terminal device side. FIG. 3 is a schematic diagram of an information processing method according to an embodiment of the present application. As shown in FIG. 3, the method comprises:
[0080] 301, the terminal device receives channel state information reference signal (CSI-RS) resource configuration information and / or channel state information (CSI) reporting setting information from the network device,
[0081] Wherein, the CSI-RS resource configuration information is used to configure at least one CSI-RS resource set, and the CSI reporting setting information comprises at least one reporting sub-configuration information, the at least one CSI-RS resource set is related to the at least one reporting sub-configuration information,
[0082] 302, the terminal device reports the CSI reporting information based on the CSI-RS resource configuration information and / or the CSI reporting setting information.
[0083] Thus, the terminal device receives CSI-RS resource configuration information for configuring at least one CSI-RS resource set and / or CSI reporting setting information including at least one reporting sub-configuration information, and reports CSI reporting information based on the CSI-RS resource configuration information and / or the CSI reporting setting information. Since the CSI-RS resource set and the reporting sub-configuration information are associated, the terminal device can determine the CSI-RS resource for measuring the CSI of the reporting sub-configuration information according to the CSI-RS resource set and / or the reporting sub-configuration information, which helps the terminal device to efficiently and accurately perform CSI measurement and reporting, ensures data transmission performance, and realizes network energy saving.
[0084] It should be noted that the above FIG. 3 only schematically illustrates the embodiments of the present application, but the present application is not limited thereto. For example, the execution order between the operations can be appropriately adjusted, and in addition, some operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the above description, and the present application is not limited to the above FIG. 3.
[0085] In some embodiments, the CSI-RS resource configuration information is used to configure at least one CSI-RS resource set, wherein one of the at least one CSI-RS resource set configured by the CSI-RS resource configuration information includes at least one CSI-RS resource. The CSI-RS resource can be a time-frequency resource, etc.
[0086] In some embodiments, the CSI reporting setting information includes at least one reporting sub-configuration information (also referred to as energy saving sub-configuration information). The reporting sub-configuration information is used to indicate a reporting sub-configuration (also referred to as a sub-configuration or an energy saving sub-configuration).
[0087] In some embodiments, the reporting sub-configuration information includes indication information of a CSI-RS resource list. The CSI-RS resource list includes at least one CSI-RS resource. The at least one CSI-RS resource in the CSI-RS resource list is a resource in the at least one CSI-RS resource set.
[0088] For example, the CSI-RS resource configuration information configures one CSI-RS resource set, and the CSI-RS resource set includes 16 CSI-RS resources, such as CSI-RS 0, CSI-RS 1, …, CSI-RS 15.
[0089] The CSI reporting setting information includes two reporting sub-configuration information, corresponding to reporting sub-configuration 1 and reporting sub-configuration 2 respectively. The two reporting sub-configuration information respectively configure CSI-RS resource list 1 and CSI-RS resource list 2 used for reporting sub-configuration 1 and reporting sub-configuration 2. For example, the CSI-RS resource list 1 includes the identifiers of the above-mentioned CSI-RS#0, CSI-RS#1, …, CSI-RS#7; the CSI-RS resource list 1 includes the identifiers of the above-mentioned CSI-RS#8, CSI-RS#9, …, CSI-RS#15. The terminal device performs CSI measurement corresponding to reporting sub-configuration 1 and reporting sub-configuration 2 according to the CSI-RS resources indicated by the CSI-RS resource list 1 and the CSI-RS resource list 2 respectively.
[0090] In some embodiments, the number of ports supported by the CSI-RS resources in the CSI-RS resource set and / or the CSI-RS resource list can be greater than a preset value. The preset value can be 32. For example, the number of ports supported by the CSI-RS resources can be 48, 64, 128, etc.
[0091] In some embodiments, based on the assumption that one CSI-RS resource supports at most 32 ports, in order to support more than 32 ports, more than one CSI-RS resources can be combined into a CSI-RS resource combination. For example, more than 32 ports can be supported by 2, 3 or 4 CSI-RS resources.
[0092] Figure 4 is a schematic diagram of a CSI-RS resource combination according to an embodiment of the present application. As shown in Figure 4, the four CSI-RS resources CSI-RS#0, CSI-RS#1, CSI-RS#2, and CSI-RS#3 form a resource combination, each CSI-RS resource supports 32 ports, and the resource combination supports 128 ports. The gNB transmits CSI-RS through the CSI-RS#0, CSI-RS#1, CSI-RS#2, and CSI-RS#3, and the UE receives the CSI-RS and performs channel measurement based on 128 ports, for example, calculates PMI, and reports the measurement result CSI to the gNB.
[0093] In some embodiments, in the scenario of supporting more than 32 ports (referred to as multi-antenna port scenario) by combining multiple CSI-RS resources into a CSI-RS resource combination, the CSI-RS resource combination can be indicated by the CSI-RS resource set and / or the CSI-RS resource list. Thus, the UE can determine which CSI-RS resources jointly support a port number greater than 32 as a combination according to the CSI-RS resource set and / or the CSI-RS resource list, so that the UE can accurately perform CSI measurement and reporting for the port number.
[0094] The above scheme is exemplarily described below.
[0095] Scheme 1:
[0096] In some embodiments, the CSI-RS resource configuration information is used to configure one first CSI-RS resource set. That is, the number of CSI-RS resource sets configured by the CSI-RS resource configuration information is 1.
[0097] In some embodiments, the CSI reporting setting information includes M1 reporting sub-configuration information, the M1 reporting sub-configuration information is related to the one first CSI-RS resource set, where M1 is an integer greater than or equal to 1.
[0098] In some embodiments, the first CSI-RS resource set can include Y1 CSI-RS resources, Y1 is an integer greater than or equal to 1. The CSI-RS resource list of the i-th reporting sub-configuration information can include Z1 i CSI-RS resources. Wherein Z1 i is a value less than or equal to Y1, i≤M1. That is, the CSI-RS resources indicated by the CSI-RS resource list can be part of the CSI-RS resources in the first CSI-RS resource set.
[0099] In some embodiments, the Z1 i CSI-RS resources included in the CSI-RS resource list of the reporting sub-configuration information can all be used for the measurement of the CSI corresponding to the reporting sub-configuration information. In other words, the CSI-RS resource combination used to support the number of antenna ports greater than 32 can be indicated by the CSI-RS resource list of the reporting sub-configuration information.
[0100] In this way, the UE can determine the CSI-RS resource combination corresponding to the reporting sub-configuration according to the CSI-RS resource list, select the CSI-RS resources in the CSI-RS resource combination from the first CSI-RS resource set for CSI measurement. The measurement result is used as the CSI reporting information.
[0101] In some embodiments, one reporting sub-configuration information can include one CSI-RS resource list, which can indicate one CSI-RS resource combination. In this case, the CSI-RS resource index (CRI) information does not need to be included in the CSI reporting information.
[0102] In some embodiments, the CSI-RS resource combinations indicated by the CSI-RS resource lists of different reporting sub-configuration information commonly support the same number of antenna ports.
[0103] In some embodiments, the number of CSI-RS resources in the CSI-RS resource combination indicated by the CSI-RS resource list in different reporting sub-configuration information is equal. The present application is not limited thereto, and the number of CSI-RS resources can also be unequal, i.e., in different reporting sub-configurations, the same number of antenna ports can be supported by different numbers of CSI-RS resources.
[0104] The present application is not limited thereto, and one reporting sub-configuration information can include one CSI-RS resource list, which can indicate more than one CSI-RS resource combination. In this case, the CSI reporting information needs to include CSI-RS resource index (CRI) information.
[0105] For example, the terminal device can select one CSI-RS resource combination from more than one CSI-RS resource combination according to an index such as RSRP (Reference Signal Receiving Power), and indicate the selected CSI-RS resource combination by one CRI.
[0106] The number of antenna ports supported by the more than one CSI-RS resource combination is the same. The number of CSI-RS resources included in the more than one CSI-RS resource combination can be the same, or can also be different.
[0107] In the case of reporting CRI, the CSI-RS resource combination can be indicated in various ways by CRI. For example, the CSI-RS resource list can indicate A CSI-RS resource combinations, A is an integer greater than 1, CRI can be indicated by logA bits, or a bit bitmap of length A.
[0108] The following is a specific exemplary description.
[0109] FIG. 5 is a schematic diagram of a CSI-RS resource set and a CSI-RS resource list according to an embodiment of the present application.
[0110] As shown in FIG. 5, the CSI-RS resource configuration information configures one CSI-RS resource set, which includes 8 CSI-RS resources, CSI-RS#0, CSI-RS#1, …, CSI-RS#7.
[0111] The CSI reporting setting information includes two reporting sub-configuration information, and the two reporting sub-configuration information respectively corresponds to different CSI-RS resources in the eight CSI-RS resources of the CSI-RS resource set. For example, the CSI-RS resource list CSI-RS list#1 of the reporting sub-configuration information Sub-Config#1 indicates CSI-RS#0, CSI-RS#1, …, CSI-RS#3 in the eight CSI-RS resources, and four CSI-RS resources are used to support P=128 ports; the CSI-RS resource list CSI-RS list#2 of the reporting sub-configuration information Sub-Config#2 indicates CSI-RS#4, CSI-RS#5, …, CSI-RS#7 in the eight CSI-RS resources, and four CSI-RS resources are used to support 128 ports.
[0112] The operation of the UE side includes:
[0113] Step 1: The terminal device receives a CSI-RS resource configuration. The CSI-RS resource configuration includes one first CSI-RS resource set for channel measurement. For example, the resource set includes eight CSI-RS resources for CSI measurement in the NES scenario 2.
[0114] Step 2: Based on the design of multiple antenna ports, the first four CSI-RS (CSI-RS#0-3) in the eight CSI-RS resources are used to measure one CSI based on 128 ports, and the last four CSI-RS (CSI-RS#4-7) in the eight CSI-RS resources are used to measure another CSI based on 128 ports.
[0115] Step 3: The terminal device receives a CSI reporting setting, wherein the CSI reporting setting includes M1=2 reporting sub-configurations, and each reporting sub-configuration includes one CSI-RS resource list configuration. The i-th CSI-RS resource list indicates Z1 i CSI-RS resources, i=1,...,M1. For different i, Z1 i may be equal or not equal.
[0116] For example, the resource list 1 in the reporting sub-configuration 1 includes Z11 resources, and the resource list 2 in the reporting sub-configuration 2 includes Z12 resources. Here, Z11=Z12=4.
[0117] The CSI-RS resource list of the reporting sub-configuration includes all CSI-RS resources used to construct the CSI-RS resource of 128 ports.
[0118] Specifically, resource list 1 in reporting sub-configuration 1 includes Z11 = 4 resources (CSI-RS#0-3), which are used to form a 128-port CSI-RS resource; resource list 2 in reporting sub-configuration 2 includes Z12 = 4 resources (CSI-RS#4-7), which are used to form another 128-port CSI-RS resource.
[0119] Step 4: The terminal device calculates a CSI based on port 128, i.e., CSI#1, based on all four resources in resource list 1 of reporting sub-configuration 1. The terminal device also calculates a CSI based on port 128, i.e., CSI#2, based on all four resources in resource list 2 of reporting sub-configuration 2. The terminal device does not need to report CRI.
[0120] Option 2:
[0121] In some embodiments, CSI-RS resource configuration information is used to configure a first CSI-RS resource set. That is, the number of CSI-RS resource sets configured by the CSI-RS resource configuration information is one. The first CSI-RS resource set includes R CSI-RS resource groups, where R is an integer greater than or equal to 1.
[0122] In some embodiments, the j-th CSI-RS resource group includes W j One CSI-RS resource, W j ≥1, j≤R. For different j, W j They can be equal or unequal.
[0123] The first CSI-RS resource set includes Y2 CSI-RS resources, among which,
[0124] In some embodiments, the CSI reporting configuration information includes M2 reporting sub-configuration information, where M2 is an integer greater than or equal to 1.
[0125] In some embodiments, the CSI-RS resource list for the i-th reporting sub-configuration information includes Z2. i One CSI-RS resource. For different i, Z2 i They can be equal or unequal.
[0126] In some embodiments, the number of reported sub-configuration information M2 can be equal to the number of CSI-RS resource groups R, that is, M2 reported sub-configuration information correspond one-to-one with R CSI-RS resource groups.
[0127] In some embodiments, the j-th CSI-RS resource group corresponds to the i-th reported sub-configuration information, Z2 i =W j. That is, the Z2 i CSI-RS resources in the CSI-RS resource list correspond to the W j CSI-RS resources in the CSI-RS resource set.
[0128] Wherein, i can be equal to j. The application is not limited thereto, and the CSI-RS resource set and the reporting sub-configuration information can also have other corresponding relationships.
[0129] In some embodiments, the CSI-RS resource list of the reporting sub-configuration information includes Z2 i CSI-RS resources, and D CSI-RS resources in the Z2 i CSI-RS resources are used for measurement of CSI corresponding to the reporting sub-configuration information, where D is less than or equal to Z2 i . In other words, one or more CSI-RS resource combinations can be indicated by the CSI-RS resource list of the reporting sub-configuration information, and one CSI-RS resource combination is used to jointly support an antenna port number greater than 32.
[0130] In this way, the UE can determine the CSI-RS resource combination corresponding to the reporting sub-configuration according to the CSI-RS resource list, select the CSI-RS resources in the CSI-RS resource combination from the CSI-RS resource set for CSI measurement, and report the measurement result as CSI reporting information.
[0131] In some embodiments, one reporting sub-configuration information can include one CSI-RS resource list, and the CSI-RS resource list can indicate more than one CSI-RS resource combination, that is, D is less than Z2 i . The CSI reporting information includes CSI-RS resource index (CRI) information.
[0132] For example, the terminal device can select one CSI-RS resource combination from more than one CSI-RS resource combination according to an index such as RSRP (Reference Signal Receiving Power), and indicate the selected CSI-RS resource combination through one CRI.
[0133] In the case of reporting CRI, the CSI-RS resource combination can be indicated in various ways through CRI. For example, the CSI-RS resource list can indicate A CSI-RS resource combinations, where A is an integer greater than 1. For example, for the CSI-RS resource list corresponding to the i-th reporting sub-configuration information, A = Z2 i / D, and the CRI information corresponding to the i-th reporting sub-configuration information is reported through log(Z2 i / D) bits. Alternatively, the CRI information corresponding to the i-th reporting sub-configuration information is reported through log(Z2 iThe bitmap is used to indicate the number of CSI-RS resource groups in the CSI-RS resource set.
[0134] In some embodiments, one CRI is reported for one reporting sub-configuration, i.e., the CSI reporting information includes M2 CRI information, wherein the M2 CRI information is related to R CSI-RS resource groups related to M2 sub-configuration information.
[0135] In some embodiments, the number of antenna ports supported by the plurality of CSI-RS resource combinations is the same. The number of CSI-RS resources included in the plurality of CSI-RS resource combinations can be the same, or can also be different.
[0136] The following is a specific exemplary description.
[0137] FIG. 6 is another schematic diagram of a CSI-RS resource set and a CSI-RS resource list according to an embodiment of the present application.
[0138] As shown in FIG. 6, the CSI-RS resource configuration information configures one CSI-RS resource set, which includes 16 CSI-RS resources, CSI-RS#0, CSI-RS#1, …, CSI-RS#15. One CSI-RS resource set includes M2=2 CSI-RS resource groups for measuring M2 reporting sub-configuration CSI.
[0139] The first CSI-RS resource group includes CSI-RS#0, CSI-RS#1, …, CSI-RS#7, wherein CSI-RS#0, CSI-RS#1, …, CSI-RS#3 of the above 8 CSI-RS resources jointly support P=128 ports, and CSI-RS#4, CSI-RS#5, …, CSI-RS#7 jointly support 128 ports.
[0140] The second CSI-RS resource group includes CSI-RS#8, CSI-RS#9, …, CSI-RS#15, wherein CSI-RS#8, CSI-RS#9, …, CSI-RS#11 of the above 8 CSI-RS resources jointly support 128 ports, and CSI-RS#12, CSI-RS#13, …, CSI-RS#15 jointly support 128 ports.
[0141] The CSI reporting setting information includes two reporting sub-configuration information, and the two reporting sub-configuration information correspond to different CSI-RS resource groups of the CSI-RS resource set respectively. For example, the CSI-RS resource list CSI-RS list#1 of the reporting sub-configuration information Sub-Config#1 indicates eight CSI-RS resources in the first CSI-RS resource group; and the CSI-RS resource list CSI-RS list#2 of the reporting sub-configuration information Sub-Config#2 indicates eight CSI-RS resources in the second CSI-RS resource group.
[0142] The operation of the UE side includes:
[0143] Step 1: The terminal device receives a CSI-RS resource configuration. The CSI-RS resource configuration includes one first CSI-RS resource set for channel measurement. For example, the resource set includes 16 CSI-RS resources for CSI measurement in the NES scenario 2.
[0144] Step 2: Based on the design of multiple antenna ports, the 16 CSI-RS resources include M2=2 groups of CSI-RS resources for measuring M2 sub-configuration CSI information.
[0145] The first group includes CSI-RS#0-7, a total of W1=8 resources, wherein the first D=4 CSI-RS (CSI-RS#0-3) are used for measuring one 128-port-based CSI assumption, and the last D=4 CSI-RS (CSI-RS#4-7) are used for measuring one 128-port-based CSI assumption.
[0146] The second group includes CSI-RS#8-15, a total of W2=8 resources, wherein the first D=4 CSI-RS (CSI-RS#8-11) are used for measuring one 128-port-based CSI assumption, and the last D=4 CSI-RS (CSI-RS#12-15) are used for measuring one 128-port-based CSI assumption.
[0147] Step 3: The terminal device receives a CSI reporting setting, wherein the CSI reporting setting includes M2=2 reporting sub-configurations, and each reporting sub-configuration includes one CSI-RS resource list configuration. The i-th CSI-RS resource list indicates Z2 i CSI-RS resources, i=1,...,M2, and different Z2 i may be equal or not equal.
[0148] For example, the resource list 1 in the reporting sub-configuration 1 includes Z21 resources, and the resource list 2 in the reporting sub-configuration 2 includes Z22 resources. Here, Z21=Z22=8.
[0149] Z2 CSI-RS resources in the i-th sub-configuration in the CSI reporting setting i W CSI-RS resources in the j-th CSI-RS resource group j correspond to each other. For example, i = j, i.e., W1= Z21, W2= Z22.
[0150] Step 4: The terminal device reports M2 CRI information, specifically, the i-th CRI information is related to the CSI-RS resource group related to the i-th reporting sub-configuration information. Specifically, the reporting bits are log(Z2 i / D). For example, CSI#1 of Sub-Config#1 and CSI#2 of Sub-Config#2 are reported, wherein CSI#1 includes CRI#1 indicated by 1 bit, and CSI#2 includes CRI#2 indicated by 1 bit.
[0151] Scheme 3:
[0152] In some embodiments, the CSI-RS resource configuration information is used to configure K second CSI-RS resource sets, where K is an integer greater than 1.
[0153] In some embodiments, one of the second CSI-RS resource sets includes Y3 CSI-RS resources, and Y3 is an integer greater than or equal to 1.
[0154] The number of CSI-RS resources included in each second CSI-RS resource set can be equal. The present application is not limited thereto, and the number of CSI-RS resources included in each second CSI-RS resource set can also be unequal.
[0155] In some embodiments, the CSI reporting setting information includes M3 reporting sub-configuration information, the M3 reporting sub-configuration information is related to the K second CSI-RS resource sets, and M3 is an integer greater than or equal to 1.
[0156] In some embodiments, the CSI-RS resource list of one reporting sub-configuration information includes Z3 CSI-RS resources, and Z3 is an integer greater than or equal to 1.
[0157] The number of CSI-RS resources included in each CSI-RS resource list can be equal. The present application is not limited thereto, and the number of CSI-RS resources included in each CSI-RS resource list can also be unequal.
[0158] In some embodiments, Z3 = Y3, i.e., the Z3 CSI-RS resources included in the CSI-RS resource list correspond to the Y3 CSI-RS resources included in the corresponding second CSI-RS resource set one by one.
[0159] In some embodiments, the CSI-RS resource list of the reporting sub-configuration information includes Z3 CSI-RS resources, all of which are used for measurement of the CSI corresponding to the reporting sub-configuration information. In other words, the CSI-RS resource list of the reporting sub-configuration information indicates one CSI-RS resource combination, which is used to jointly support an antenna port number greater than 32.
[0160] In this way, the UE can determine one CSI-RS resource combination corresponding to the reporting sub-configuration according to the CSI-RS resource list, and perform CSI measurement on the CSI-RS resources. The measurement result is reported as the CSI reporting information.
[0161] In some embodiments, one CSI-RS resource list can be included in one reporting sub-configuration information, which can indicate one CSI-RS resource combination. In this case, the CSI-RS resource index (CRI) information does not need to be included in the CSI reporting information.
[0162] In some embodiments, the CSI-RS resource combinations indicated by the CSI-RS resource lists of different reporting sub-configuration information jointly support equal antenna port numbers.
[0163] In some embodiments, the number of CSI-RS resources in the CSI-RS resource combinations indicated by the CSI-RS resource lists of different reporting sub-configuration information is equal. The present application is not limited thereto, and the number of CSI-RS resources described above can also be unequal, that is, in different reporting sub-configurations, the same number of antenna ports can be supported by different numbers of CSI-RS resources.
[0164] The present application is not limited to the case where the CSI-RS resource list of the reporting sub-configuration information includes Z3 CSI-RS resources, some of which are used for measurement of the CSI corresponding to the reporting sub-configuration information. In other words, the CSI-RS resource list of the reporting sub-configuration information indicates more than one CSI-RS resource combination, each of which is used to jointly support an antenna port number greater than 32. In this case, the CSI-RS resource index (CRI) information needs to be included in the CSI reporting information.
[0165] For example, the terminal device can select one CSI-RS resource combination from more than one CSI-RS resource combination according to an index such as RSRP (Reference Signal Receiving Power), and indicate the selected CSI-RS resource combination through one CRI.
[0166] The number of antenna ports supported by the plurality of CSI-RS resource combinations is the same. The number of CSI-RS resources included in the plurality of CSI-RS resource combinations can be the same, or can also be different.
[0167] In the case of reporting CRI, the CSI-RS resource combination can be indicated in various ways through CRI. For example, the CSI-RS resource list can indicate A CSI-RS resource combinations, A is an integer greater than 1, CRI can be indicated by logA bits, or a length of A bit bitmap.
[0168] The following is a specific exemplary description.
[0169] FIG. 7 is another schematic diagram of a CSI-RS resource set and a CSI-RS resource list according to an embodiment of the present application.
[0170] As shown in FIG. 7, the CSI-RS resource configuration information configures K=2 CSI-RS resource sets, each of which includes Y3=4 CSI-RS resources, CSI-RS resource set 1 includes CSI-RS#0, CSI-RS#1, …, CSI-RS#3, and CSI-RS resource set 2 includes CSI-RS#4, CSI-RS#5, …, CSI-RS#7.
[0171] The CSI reporting setting information includes M3=2 reporting sub-configuration information, and the two reporting sub-configuration information correspond to two CSI-RS resource sets, respectively. For example, the CSI-RS resource list CSI-RS list#1 of the reporting sub-configuration information Sub-Config#1 corresponds to the CSI-RS resource set 1, and 128 ports are supported through the four CSI-RS resources of the CSI-RS resource set 1; the CSI-RS resource list CSI-RS list#2 of the reporting sub-configuration information Sub-Config#2 corresponds to the CSI-RS resource set 2, and 128 ports are supported through the four CSI-RS resources of the CSI-RS resource set 2.
[0172] The operation of the UE side includes:
[0173] Step 1: The terminal device receives the CSI-RS resource configuration. The CSI-RS resource configuration includes K=2 second CSI-RS resource sets for channel measurement. For example, each resource set includes 4 CSI-RS resources, which are used for CSI measurement under NES scenario 2.
[0174] Step 2: Based on the design of multiple antenna ports, the four CSI-RS of each resource set are all used to measure a 128-port-based CSI.
[0175] Step 3: the terminal device receives CSI reporting setting, wherein the CSI reporting setting includes M3=2 reporting sub-configurations, each reporting sub-configuration includes one CSI-RS resource list configuration. One CSI-RS resource list indicates Z3 i CSI-RS resources, i=1,...,M3, for different i, Z3 i may be equal or not equal.
[0176] The CSI-RS resource list of the reporting sub-configuration includes all the CSI-RS resources used to constitute the 128-port CSI-RS resource.
[0177] Specifically, the resource list 1 in the reporting sub-configuration 1 includes Z11=4 resources (CSI-RS#0-3), and the 4 resources are used to constitute one 128-port CSI-RS resource; the resource list 2 in the reporting sub-configuration 2 includes Z12=4 resources (CSI-RS#4-7), and the 4 resources are used to constitute another 128-port CSI-RS resource.
[0178] The 4 resources of the resource list 1 in the reporting sub-configuration 1 are one-to-one corresponding to the 4 resources of the CSI-RS resource set 1; the 4 resources of the resource list 2 in the reporting sub-configuration 2 are one-to-one corresponding to the 4 resources of the CSI-RS resource set 2.
[0179] Step 4: the UE side calculates the CSI information based on 128 ports, i.e., CSI#1, based on all the 4 resources in the list 1 in the sub-configuration 1, and the UE side calculates the CSI information based on 128 ports, i.e., CSI#2, based on all the 4 resources in the list 2 in the sub-configuration 2. The terminal device does not need to report CRI.
