Description

Technical Field

[0001] Embodiments of the present invention relate to the field of communication technologies.

Background Art

[0002] As an important component of the world's new infrastructure construction, the fifth-generation (5G) communication network has witnessed rapid development worldwide in recent years. With the construction of 5G, the Active Antenna Unit (AAU) has been widely commercialized. Compared with the Remote Radio Unit (RRU) mainly used in 3G and 4G, the power consumption of AAU is high, so the energy consumption of 5G equipment will also double.

[0003] 5G defines three major service types: Enhanced Mobile Broadband (eMBB), massive Machine Type of Communication (mMTC), and Ultra Reliable Low Latency Communication (URLLC). As a result, the bursty services of 5G packets continue to increase, the base station operates 24 hours without rest, and the average daily energy consumption of 5G sites is more than twice that of 4G.

[0004] In addition, the 3GPP (registered trademark) has introduced important technologies such as Massive MIMO and a wider radio frequency band in the 5G era. 5G supports higher data rates and larger data traffic, requiring more transmission bandwidth, and the deployment of high-frequency bands will become the main frequency bands for the future expansion of 5G. On the other hand, the transmission characteristics of high-frequency bands limit the communication range of sites, so the deployment of 5G sites becomes concentrated, and the increase in site power consumption puts great operating cost pressure on operators.

[0005] As the scale of a network grows, the energy consumption of operators continues to increase. For example, data released by China's Ministry of Industry and Information Technology indicates that energy consumption in 2022 is projected to increase by approximately 80% compared to 2015. Therefore, network energy conservation is of crucial importance for reducing operating costs, and 5G network energy conservation is an issue that needs to be addressed urgently.

[0006] To achieve energy savings, network devices can perform energy-saving processes in the time domain, frequency domain, spatial domain, and / or energy domain, respectively, based on the network load. For example, in the spatial and energy domains, network devices can achieve energy savings by turning off some antennas when the load is low, and in the time domain, network devices may implement cell-level discontinuous transmission / reception techniques so that the network device does not transmit and / or receive signals during certain periods of inactivity, in order to achieve energy savings.

[0007] On the other hand, with the development of mobile communication technology and the deepening of mobile network deployment, low-spectrum resources are becoming increasingly scarce. To meet the demands for higher transmission speeds and greater system capacity, higher spectrum, such as millimeter waves, is being considered for 5G systems. While more abundant high-spectrum resources can provide continuous and wide bandwidth, the transmission characteristics of millimeter waves are not ideal, resulting in problems such as high transmission loss, susceptibility to signal shielding and blocking.

[0008] Therefore, 5G systems introduce a series of technological schemes, such as digital + analog mixed beamforming, which converts signals transmitted in all directions into multiple beams and uses very narrow beam alignment transmission, allowing transmitted signals to propagate over longer distances and improving the quality of communication links.

[0009] Furthermore, the above explanation of the background art is merely intended to provide a clearer and more complete explanation of the present invention's structure and to facilitate understanding for those skilled in the art. These structures, as described in the background art section of the present invention, should not be construed as being well-known to those skilled in the art.

[0032] The following describes a scenario of an embodiment of the present invention with reference to an example, but the present invention is not limited thereto.

[0033] Figure 1 is a schematic diagram of a communication system according to an embodiment of the present invention, schematically showing examples of terminal devices and network devices. As shown in Figure 1, the communication system 100 may include a network device 101 and terminal devices 102 and 103. For the sake of explanation, Figure 1 is described using two terminal devices and one network device as an example, but embodiments of the present invention are not limited thereto.

[0034] In embodiments of the present invention, existing services or services that can be implemented in the future can be provided between the network device 101 and the terminal devices 102 and 103. For example, these services include, but are not limited to, enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra-reliable and low-latency communication (URLLC), and related communications for terminal devices with reduced capabilities.

[0035] Although Figure 1 shows that both terminal devices 102 and 103 are located within the coverage area of ​​network device 101, the present invention is not limited to this. Neither of the two terminal devices 102 and 103 are located within the coverage area of ​​network device 101, or one terminal device 102 may be located within the coverage area of ​​network device 101 and the other terminal device 103 may be located outside the coverage area of ​​network device 101.

[0036] In embodiments of the present invention, the upper-layer signaling may be, for example, a radio resource control (RRC) signaling. The RRC signaling includes, for example, an RRC message, and includes, for example, a master information block (MIB), system information, a dedicated RRC message, or an RRC information element (RRC IE). Alternatively, the upper-layer signaling may be, for example, a medium access control (MAC) signaling, or may be referred to as a MAC control element (MAC CE). However, the present invention is not limited to these.

[0037] In embodiments of the present invention, in a mobile communication system, terminal devices typically measure channel state information (CSI) based on instructions and configurations of network devices and report the measured CSI to the network devices. When scheduling terminal devices, the network devices can refer to the CSI to schedule terminal devices to transmit using the appropriate transmission method on the appropriate resources. Because different terminal devices may have different physical channel conditions, using a CSI feedback mechanism allows for the rational and efficient use of physical resources, thereby improving the overall transmission efficiency of the network.

[0038] In the NR's CSI feedback mechanism, terminal devices measure and report reference signals primarily based on the CSI configuration. Reference signals include CSI-RS (Channel State Indication-Reference Signal) and SSB (Synchronization Signal Block), among others. The NR's CSI configuration is mainly divided into two parts: the first part is the network device configuring the reference resources for CSI measurement of terminal devices (CSI-RS resource configuration), and the second part is the network device configuring the terminal device's CSI reporting method (CSI reporting configuration).

[0039] For example, a CSI-RS resource setting can be used for both interference measurements and CSI channel measurements. Each CSI-RS resource setting contains S resource sets. Each resource set contains Ks CSI-RS resources. A non-periodic resource setting can contain one or more resource sets. Periodic and semi-persistent resource settings are used for CSI acquisition and can contain only one resource set.

[0040] The value of Ks is as follows:

[0041] When used for CSI channel measurement, Ks ≤ 32 when the reporting setting's codebook type is "Type I" (specifically, this can include CodebookType = "TypeISinglePanle" or "TypeIMultiPanle").

[0042] When used for CSI channel measurement, Ks=1 when the reporting setting's codebook type is "Type II" (specifically, CodebookType="typeII", "typeII-PortSelection", "typeII-r16", "typeII-PortSelection-r16", "typeII-PortSelection-r17"). This is mainly because the computational complexity of Type II is relatively high, making it difficult to compute terminal devices, so the NR system reduces the computational complexity of terminal devices relatively by limiting the value of Ks.

[0043] A CSI report consists of two parts: Part 1 and Part 2, where Part 1 of the CSI has a fixed load size and Part 2 of the CSI indicates the number of information bits. In a CSI report, when the current CSI measurement is used for CSI channel measurement, the following reporting contents are specified depending on the different codebook type:

[0044] Type I CSI: Part 1 includes the RI / CRI and the CQI of the first CW, and Part 2 includes the LI and PMI, and if the rank is greater than 4, it further includes the CQI of the second CW.

[0045] Type II CSI: Part 1 includes the RI, CQI, and the number of non-zero broadband amplitude coefficients for each layer, while Part 2 includes the LI and PMI.

[0046] NR supports interference measurements based on CSI-IM, primarily for measuring adjacent cell interference. The power of this CSI-IM may or may not be zero. The signal measured by the CSI-IM is generally assumed to be the PDSCH of the adjacent cell. The CSI-IM resource may be periodic, semi-persistent, or aperiodic in the time domain. Typically, the resources in the configured CSI resource set for interference measurements correspond one-to-one with the resources for channel measurements.

[0047] The NR system further supports interference measurements based on non-zero power (NZP) CSI-RS. When a single NZP CSI-RS resource is configured solely for interference measurements, the UE assumes that each CSI-RS port corresponds to one interference transport layer. The UE sums the interference measurements for all interference layers, and the interference for each layer must take into account its corresponding power factor. This method is suitable for pre-scheduled interference measurements. The measurement results for this interference from the NZP CSI-RS resource include both inter-MU interference and inter-cell interference. When a single NZP CSI-RS resource is configured for both channel measurements and interference measurements, the terminal equipment (UE) can subtract the channel measurement from the signal after the channel measurement to obtain the interference measurement result. Due to the low density of NZP CSI-RS, channel measurements are inaccurate, and the corresponding interference measurements are also inaccurate. Therefore, interference measurements based on NZP CSI-RS are suitable for pre-scheduled measurements of inter-user interference and are only suitable for aperiodic CSI reporting. An NZP CSI-RS resource set used for interference measurement may contain multiple NZP CSI-RS resources, each used for interference measurement, with a total of 18 ports or less.

[0048] In conventional technology, the CSI-RS resource configuration is a semi-static RRC configuration, and the number of CSI-RS ports and their time-frequency positions do not change over long periods of time.

[0049] However, the inventors of this invention have discovered that in network energy saving scenarios, one viable solution for achieving network energy saving is for the network equipment to adjust the antenna configuration for serving terminal equipment, such as the number of antenna elements and antenna ports, based on the real-time demands of the network. Here, R18 (Release-18) mainly supports the following two energy saving scenarios in this application, depending on the implementation limitations of the network equipment hardware, radio frequency, etc.

[0050] Figure 2 is a schematic diagram of an example of an energy-saving scenario according to an embodiment of the present invention. The left side of Figure 2 may be referred to as type 1 adjustment, and for example, in response to energy-saving scenario 1, all antennas (factors) associated with one logical antenna port are enabled or disabled, and this adjustment directly affects the number of antenna ports. The right side of Figure 2 may be referred to as type 2 adjustment, and for example, in response to energy-saving scenario 2, a partial antenna factor associated with one logical antenna port is enabled or disabled, and this adjustment affects the beamforming gain of the network device and further affects the transmission power of the reference signal.

[0051] As shown in Figure 2, energy saving scenario 1 achieves network energy savings by turning off some of the digital antenna ports. When a different number of antenna ports are turned off on the terminal device side, the terminal device performs measurements based on a different number of ports and generates CSI information for different digital ports. Therefore, "nrofports" in the CSI resource configuration and N1N2 in the reporting settings may have different values ​​in different energy saving configurations. Consequently, the number of antenna port dimensions in the PMI matrix in the reported CSI will differ in different energy saving subconfigurations. In the most common energy saving scenario 1, the distinction between subconfigurations of different antenna ports can be indicated by the antenna ports within a single CSI-RS resource; for example, different subsets of antenna ports within a CSI-RS resource can correspond to different antenna port off configurations.

[0052] Furthermore, energy saving can be achieved by adjusting the transmit power simultaneously with turning off or adjusting the antenna configuration. Specifically, based on the Poweroffset information in the network configuration information, CSI channel measurements can be performed based on the assumption of data transmit power not used by the termination device, and this can be fed back to the network side to provide a more accurate channel state for energy saving adjustments of the network device. This power adjustment can be configured simultaneously with energy saving scenarios 1 and 2, achieving both the objective and effect of energy saving.

[0053] As shown in Figure 2, in energy-saving scenario 2, network energy savings are achieved by dynamically adjusting the number of TXRU / radio frequency antennas without adjusting the number of digital antenna ports. Therefore, in this case, the "nrofports" in the CSI resource configuration and / or N1N2 in the reporting settings do not change in different energy-saving subconfigurations, and the number of antenna port dimensions in the PMI matrix in the reported CSI does not change, so the protocol may be transparent to the terminal device. In the most common scenario for energy-saving scenario 2, different antenna port subconfigurations can be distinguished by different CSI-RSs, for example, different resources correspond to different antenna port off configurations.

[0054] In both energy-saving scenarios, the existing CSI resource configurations are not sufficiently compatible and are not redundant. In the Type I codebook, currently all resources within a single resource set correspond to the same antenna port, and the terminal device can select and report only one CSI-RS resource for measurement reporting. Therefore, the terminal device cannot report CSI results for different antenna ports. In the Type II codebook, currently only one CSI-RS resource is supported within a single resource set, and it is not possible to report the CRI (optimal CSI-RS resource). Therefore, the terminal device cannot report CSI results for different antenna ports, especially in energy-saving scenario 2.

[0055] Therefore, when enhancing existing CSI resource configurations with different energy-saving scenarios, the CSI reporting information must also be enhanced accordingly. Otherwise, the network side will not be able to accurately obtain CSI information for all energy-saving configurations, making efficient and accurate energy saving impossible.

[0056] When network devices adjust their antenna configurations (for example, for energy saving purposes), efficiently and accurately performing CSI measurements on terminal devices is an urgent issue that needs to be resolved.

[0057] <Example 1> An embodiment of the present invention provides an information receiving method, which will be described from the terminal device side. Figure 3 is a schematic diagram of an example of an information receiving method according to an embodiment of the present invention. As shown in Figure 3, the method includes the following steps.

[0058] Step 301: The terminal device receives the first CSI-RS resource configuration information and / or the first CSI report configuration information.

[0059] Here, the first CSI-RS resource configuration information constitutes at least one first CSI-RS resource set, each of which includes at least one CSI-RS resource, the first CSI report configuration information constitutes first CSI report information corresponding to at least M sub-configurations, the first CSI-RS resource configuration information relates to first CSI report information corresponding to M sub-configurations in the first CSI report configuration information, where M is an integer of 1 or more.

[0060] As a result, terminal devices can accurately perform CSI reporting based on the first CSI-RS resource configuration information and / or the first CSI reporting configuration information, and network devices can accurately receive and demodulate the received CSI, thereby improving the accuracy and completeness of measurement reports and guaranteeing data transmission performance.

[0061] Figure 3 above merely provides a schematic representation of an embodiment of the present invention, but the present invention is not limited thereto. For example, the execution order between various steps may be appropriately adjusted, or several other steps may be added or several steps removed. Those skilled in the art can make appropriate modifications based on the above description and are not limited to the description in Figure 3.

[0062] In some embodiments, M subconfigurations refer to subconfigurations of an existing first CSI-RS resource configuration.

[0063] For example, if a first CSI-RS resource configuration consists of 64 ports, then M subconfigurations can mean, for example, subconfigurations of these 64 ports. For example, if M=3, it corresponds to the first subconfiguration (64 ports), the second subconfiguration (32 ports), and the third subconfiguration (16 ports), respectively. For example, all ports corresponding to M subconfigurations are subsets of the 64 ports configured for the first CSI-RS resource configuration.

[0064] In some embodiments, each first CSI-RS resource set includes at least one CSI-RS resource, for example, each first CSI-RS resource set includes 16 CSI-RS resources, as will be illustrated in detail later in this specification.

[0065] In some embodiments, the first CSI reporting configuration information constitutes first CSI reporting information corresponding to at least M subconfigurations, which includes: the first CSI reporting configuration information includes at least one instruction information, wherein the instruction information indicates port information for the M subconfigurations.

[0066] For example, the first CSI report configuration information can include multiple instruction pieces or one instruction piece. For example, in the energy saving scenario 1 shown in Figure 2, multiple instruction pieces can specify the port information for M configurations. For example, in the energy saving scenario 2 shown in Figure 2, one instruction piece can configure the port information for M sub-configurations, where the port information for the M sub-configurations is identical. The following will be explained with reference to examples.

[0067] In some embodiments, the first CSI report configuration information includes M instruction information, the i-th instruction information of which includes configuration information for Ni ports, the range of the value of i is an integer in {1, M}, the i-th instruction information indicates the number of ports of the i-th subconfiguration out of M subconfigurations, and the number of ports of each subconfiguration out of M subconfigurations is the same or different.

[0068] For example, the first instruction information includes configuration information for N1 ports corresponding to the first subconfiguration, and so on, with N2, N3...NM included in the second to Mth instruction information each corresponding to configuration information for M ports corresponding to subconfigurations.

[0069] For example, N1 > N2 > N3 ... > NM, and taking M=3 as an example, N1=64, N2=32, N3=16, where the ports of the second and third subconfigurations may be subsets of the ports of the first subconfiguration, for example, the 32 ports of the second subconfiguration are half the 64 ports of the first subconfiguration.

[0070] For example, N1=N2=N3…=NM. Here, the number of ports corresponding to the M subconfigurations is the same, for example, 32 in each case.

[0071] For example, the above set of instructions can be applied to energy-saving scenario 1.

[0072] In some embodiments, the first CSI report configuration information includes one instruction, which indicates the number of ports for M subconfigurations, and each of the M subconfigurations has the same number of ports.

[0073] For example, one instruction directly indicates the number of ports N for M subconfigurations, where the number of ports corresponding to the M subconfigurations is the same, for example, N=4.

[0074] For example, the number of ports corresponding to M subconfigurations is the same, but the number of antennas for the corresponding number of ports is different, for example, M=4 and N=4, and for example, a 32-physical antenna configuration for 4 ports (corresponding to the first subconfiguration), a 16-physical antenna configuration (corresponding to the second subconfiguration), a 12-physical antenna configuration (corresponding to the third subconfiguration), and an 8-physical antenna configuration (corresponding to the fourth subconfiguration), and for example, the physical antenna configuration may be transparent to the terminal device side.

[0075] For example, the above instruction information may be applied to energy-saving scenario 2.

[0076] The following explains, with the help of an example, how CSI-RS resources are determined for channel measurements of M subconfigurations.

[0077] In some embodiments, each first CSI-RS resource set includes K CSI-RS resources, and each of the K CSI-RS resources is used to determine channel measurements for M sub-configurations.

[0078] For example, K is an integer greater than or equal to 1, for instance, K=16, and the first CSI-RS resource set contains 16 CSI-RS resources.

[0079] For example, in energy-saving scenario 1, where M=3 (there are three subconfigurations), the 16 CSI-RS resources may each be used to measure channel information for subconfigurations with 64, 32, and 16 ports, respectively. The present invention is not limited to, for example, prior art for specific measurement methods. The terminal device reports the results after measurement (details are described in detail later in the specification).

[0080] In some embodiments, the CSI-RS resources associated with each subconfiguration within M subconfigurations are identical, and the M subconfigurations are associated with all CSI-RS resources in the first CSI-RS resource set in the first CSI-RS resource configuration information.

[0081] For example, in energy-saving scenario 1, if K=2 and M=2, then the first CSI report configuration information may contain two sub-configurations of CSI report information, and the first CSI-RS resource set in the first CSI-RS resource configuration information related to the report information contains K=2 CSI-RS resources, for example, {CSI-RS#1,CSI-RS#2}. Here, the CSI-RS resources related to the first sub-configuration are {CSI-RS#1,CSI-RS#2}, and the CSI-RS resources related to the second sub-configuration are also {CSI-RS#1,CSI-RS}.

[0082] For example, a network device may not configure a subconfiguration for a terminal device where the CSI-RS resources are {CSI-RS#1,CSI-RS#2} and the CSI-RS resources are {CSI-RS#2,CSI-RS#3}, or a terminal device may not expect / not be configured to have a subconfiguration where the CSI-RS resources are {CSI-RS#1,CSI-RS#2} and the CSI-RS resources are {CSI-RS,CSI-RS#1}.

[0083] In some embodiments, the first CSI report configuration information corresponding to M subconfigurations includes a power offset for the first portion of the M subconfigurations, but not for the second portion of the M subconfigurations.

[0084] For example, some of the M subconfigurations have a power offset, while the remaining M subconfigurations do not.

[0085] For example, power offsets for different sub-configurations are represented by a power offset index. Here, specific details regarding power offsets can be found in the prior art, and the present invention is not limited thereto. For example, power offset 0 indicates that the current power offset value is 0, or that no power offset is configured for the terminal device, power offset 1 indicates that the current power offset value is 3dB, and the present invention is not limited thereto.

[0086] In some embodiments, if no power offset is configured for the second subconfiguration of the M subconfigurations, the terminal device determines that the current power offset value for the second subconfiguration is 0.

[0087] For example, for a subconfiguration in which no power offset is configured, the terminal device assumes that the power offset value corresponding to that subconfiguration is 0, or that the power offset index corresponding to that subconfiguration is fixed (default), for example, power offset 0.

[0088] For example, in energy-saving scenario 1, if K=2 and M=2, the first CSI report configuration information includes a first subconfiguration {CSI-RS#1, CSI-RS#2} (with power offset 1) and a second subconfiguration {CSI-RS#1, CSI-RS#2} (without power offset, or with power offset 0).

[0089] In some embodiments, a power offset is configured for all M subconfigurations in the first CSI report configuration information corresponding to M subconfigurations.

[0090] For example, all M subconfigurations have a power offset. For instance, in energy-saving scenario 1, taking K=2 and M=2 as an example, the first CSI report configuration information includes the first subconfiguration {CSI-RS#1,CSI-RS#2} (with power offset 1) and the second subconfiguration {CSI-RS#1,CSI-RS#2} (with power offset 2).

[0091] In some embodiments, each first CSI-RS resource set contains K CSI-RS resources, where K = M, and one of the K CSI-RS resources is used to determine the channel measurement of one of the M subconfigurations.

[0092] For example, K is an integer greater than or equal to 1, for example, K = M, and the first CSI-RS resource set contains 3 CSI-RS resources.

[0093] For example, in energy-saving scenario 2, taking M=4 (four subconfigurations) as an example, four CSI-RS resources correspond to four subconfigurations, and each CSI-RS resource is used to measure channel information for one subconfiguration. For example, specific measurement methods may refer to prior art, and the present invention is not limited thereto. The terminal device reports based on the measurement results (details are described in subsequent parts of the specification).

[0094] In some embodiments, each first CSI-RS resource set includes Z CSI-RS resource groups, where the m-th CSI-RS resource group of the Z CSI-RS resource groups relates to Zm CSI-RS resources out of H CSI-RS resources, where Zm is a positive integer and Zm ≤ H, and the m-th sub-configuration information corresponding to the m-th CSI-RS resource group includes the CSI-RS resource identifiers (IDs) of the Zm CSI-RS resources, where 1 ≤ m ≤ M.

[0095] In some embodiments, Z = M, and Z CSI-RS resource groups correspond one-to-one with M subconfigurations.

[0096] For example, Z is an integer greater than or equal to 1, Z=M, H=16, and for example, the first CSI-RS resource set includes 3 CSI-RS resource groups and 16 CSI-RS resources, where the 3 CSI-RS resource groups correspond one-to-one to 3 sub-configurations.

[0097] For example, the expression "CSI-RS resource group" above may be replaced with "CSI-RS resource list," etc., but the present invention is not limited thereto.

[0098] Figure 9 is a schematic diagram of an example of the correspondence between subconfigurations and CSI-RS resource identifiers (IDs) according to an embodiment of the present invention. As shown in Figure 9, the CSI-RS resource identifiers (IDs) corresponding to subconfiguration 1 of the CSI reporting configuration are CSI-RS#0--CSI-RS#7, Z1=8, indicating that the first subconfiguration information relates to the first 8 CSI-RS resources CSI-RS#0--CSI-RS#7 out of 16 CSI-RS resources. The CSI-RS resource identifiers (IDs) corresponding to subconfiguration 2 of the CSI reporting configuration are CSI-RS#8--CSI-RS#10, Z2=3, indicating that the second subconfiguration information relates to 16 C This indicates that the 9th to 11th CSI-RS resources CSI-RS#8--CSI-RS#10 (a total of 3 resources) are related to the SI-RS resources, and the CSI-RS resource identifier (ID) corresponding to CSI Report Configuration Subconfiguration 2 is CSI-RS#8--CSI-RS#10, Z3=5, indicating that the 3rd subconfiguration information is related to the 12th to 16th CSI-RS resources CSI-RS#11--CSI-RS#15 (a total of 5 resources) out of the 16 CSI-RS resources.

[0099] As shown in Figure 9, here Z1=8, Z2=3, and Z3=5, and the sum of the values ​​of Zm = 8+3+5=16, which is equal to H. Although not shown in Figure 9, Z1, Z2, and Z3 may be equal, and the sum of the values ​​of Zm may be less than H, but the present invention is not limited to these.

[0100] In some embodiments, the first CSI report configuration information corresponding to M subconfigurations does not configure power offsets for all M subconfigurations.

[0101] In some embodiments, the CSI-RS resources associated with each of the M subconfigurations are orthogonal, and the M subconfigurations are associated with at least one CSI-RS resource in the first CSI-RS resource set in the first CSI-RS resource configuration information.

[0102] For example, in energy-saving scenario 2, if K=6 and M=3, the first CSI report configuration information may contain three sub-configurations of CSI report information, and the first CSI-RS resource set in the first CSI-RS resource configuration information related to this CSI report information contains K=6 CSI-RS resources. For example, the first sub-configuration may configure the related CSI-RS list in the first CSI report configuration information as {CSI-RS#1,CSI-RS#2}, the second sub-configuration may configure the related CSI-RS list in the first CSI report configuration information as {CSI-RS#3,CSI-RS#4}, and the third sub-configuration may configure the related CSI-RS list in the first CSI report configuration information as {CSI-RS#5,CSI-RS#6}, and none of the first, second, and third sub-configurations contain a power offset.

[0103] In some embodiments, a power offset is configured for all M subconfigurations in the first CSI report configuration information corresponding to M subconfigurations.

[0104] In some embodiments, the CSI-RS resources associated with each of the M subconfigurations are orthogonal or identical.

[0105] For example, in energy-saving scenario 2, if K=4 and M=4, the first CSI report configuration information may contain four sub-configurations of CSI report information, and the first CSI-RS resource set in the first CSI-RS resource configuration information related to this CSI report information contains K=4 CSI-RS resources. For example, the first sub-configuration may configure the related CSI-RS list as {CSI-RS#1,CSI-RS#2} within the first CSI report configuration information and configure power offset 1. The second sub-configuration may configure the related CSI-RS list as {CSI-RS#1,CSI-RS#2} within the first CSI report configuration information and configure power offset 2. The third sub-configuration may configure the related CSI-RS list as {CSI-RS#3,CSI-RS#4} within the first CSI report configuration information and configure power offset 1. A fourth subconfiguration may be configured within the first CSI reporting configuration information, where the relevant CSI-RS list is configured as {CSI-RS#3,CSI-RS#4}, and power offset 2 is configured.

[0106] In some embodiments, if the CSI-RS resources associated with each of the M subconfigurations are orthogonal, the power offsets corresponding to the M subconfigurations may be different or identical.

[0107] For example, the first subconfiguration described above may configure the associated CSI-RS list as {CSI-RS#1,CSI-RS#2} in the first CSI report configuration information and configure power offset 1. The third subconfiguration described above may configure the associated CSI-RS list as {CSI-RS#3,CSI-RS#4} in the first CSI report configuration information and configure power offset 1. Also, for example, the first subconfiguration described above may configure the associated CSI-RS list as {CSI-RS#1,CSI-RS#2} in the first CSI report configuration information and configure power offset 1. The fourth subconfiguration described above may configure the associated CSI-RS list as {CSI-RS#3,CSI-RS#4} in the first CSI report configuration information and configure power offset 2.

[0108] In some embodiments, if the CSI-RS resources associated with each of the M subconfigurations are identical, the power offsets corresponding to the M subconfigurations are different.

[0109] For example, the first subconfiguration described above may configure the associated CSI-RS list as {CSI-RS#1,CSI-RS#2} in the first CSI report configuration information to configure power offset 1. The second subconfiguration described above may configure the associated CSI-RS list as {CSI-RS#1,CSI-RS#2} in the first CSI report configuration information to configure power offset 2.

[0110] In some embodiments, the first CSI report configuration information corresponding to M subconfigurations includes a power offset for the first portion of the M subconfigurations, but not for the second portion of the M subconfigurations.

[0111] In some embodiments, the CSI-RS resources associated with each of the M subconfigurations are orthogonal or identical.

[0112] For example, if the CSI-RS resources associated with each subconfiguration within M subconfigurations are orthogonal, the following applies:

[0113] For example, in energy-saving scenario 2, if K=4 and M=2, then two sub-configurations of CSI report information are configured within the first CSI report information, and the first CSI-RS resource set within the first CSI-RS resource configuration information associated with this CSI report information contains K=4 CSI-RS resources. For example, the first sub-configuration may configure the associated CSI-RS list within the first CSI report configuration information as {CSI-RS#1,CSI-RS#2} and configure power offset 1. The second sub-configuration may configure the associated CSI-RS list within the first CSI report configuration information as {CSI-RS#3,CSI-RS#4} and either not configure a power offset or configure power offset=0.

[0114] For example, if the CSI-RS resources associated with each subconfiguration within M subconfigurations are identical, then the following applies:

[0115] For example, in energy-saving scenario 2, taking K=2 and M=2 as an example, the first CSI report configuration information may contain two sub-configurations of CSI report information, and the first CSI-RS resource set of the first CSI-RS resource configuration information associated with this CSI report information may contain K=2 CSI-RS resources. For example, the first sub-configuration may configure the CSI-RS list associated with the first CSI report configuration information as {CSI-RS#1,CSI-RS#2} and configure power offset 1. The second sub-configuration may configure the CSI-RS list associated with the first CSI report configuration information as {CSI-RS#1,CSI-RS#2} and either not configure power offset or configure power offset=0.

[0116] In some embodiments, the expression "the CSI-RS resources associated with each of the M subconfigurations are identical" may be replaced with "in the first CSI reporting configuration information comprising M subconfiguration information, the CSI-RS resource identifiers (IDs) of all CSI-RS resources in the associated resource lists within the M subconfiguration information are identical," or "among the M subconfigurations expected / configured / scheduled to the terminal device, the CSI-RS resource IDs (IDs) of all CSI-RS resources in the associated resource lists are identical," or "among the M child configurations configured / scheduled by the network device, the CSI-RS resource IDs (IDs) of all CSI-RS resources in the associated resource lists are identical."

[0117] In some embodiments, the expression "the CSI-RS resources associated with each of the M subconfigurations are orthogonal" may be replaced with "the CSI-RS resource identifiers (IDs) of all CSI-RS resources in the associated resource list within the first CSI reporting configuration information constituting the M subconfiguration information are completely different among the M subconfiguration information," or "the CSI-RS resource IDs (IDs) of all CSI-RS resources in the associated resource list are completely different among the M subconfigurations expected / configured / scheduled by the terminal device," or "the terminal device does not expect the CSI-RS resource IDs (IDs) to overlap for all CSI-RS resources in the associated resource list among the M subconfigurations," or "the CSI-RS resource IDs (IDs) of all CSI-RS resources in the associated resource list are completely different among the M subconfigurations configured / scheduled by the network device."

[0118] In some embodiments, the terminal device reports N CSI-RS resource index values ​​(CRIs), where N is less than or equal to M.

[0119] For example, for N=M, the following applies:

[0120] For example, the value of the m-th CRI out of M CRIs is i_m, and the m-th CRI is associated with the i_m+1-th CSI-RS resource out of Zm CSI-RS resources associated with the m-th sub-configuration information out of M sub-configuration information, where 1 ≤ n ≤ N and 1 ≤ m ≤ M. For example, the CSI-RS resources may be NZP CSI-RS for channel measurement and / or CSI-IM for interference measurement and / or NZP CSI-RS for interference measurement.

[0121] For example, taking K = 4 and M = 2 as an example, two sub-configuration CSI report information may be configured within the first CSI report configuration information, and the first CSI-RS resource set within the first CSI-RS resource configuration information related to this CSI report information includes K = 4 CSI-RS resources. For example, the first sub-configuration may configure the related CSI-RS list as {CSI-RS#1, CSI-RS#2} and configure a power offset of 1 within the first CSI report configuration information. The second sub-configuration may configure the related CSI-RS list as {CSI-RS#3, CSI-RS#4} within the first CSI report configuration information, and not configure a power offset, or configure a power offset = 0. The terminal device reports two CRIs corresponding to the first sub-configuration and the second sub-configuration respectively.

[0122] For example, for N < M, it is as follows.

[0123] For example, the value of the m-th CRI among N CRIs is i_m, and the m-th CRI is related to the (i_m + 1)-th CSI-RS resource among Zm CSI-RS resources related to the m-th sub-configuration information among M sub-configuration information. Here, 1 ≤ n ≤ N and 1 ≤ m ≤ M. For example, the CSI-RS resource may be NZP CSI-RS for channel measurement, and / or CSI-IM for interference measurement, and / or NZP CSI-RS for interference measurement.

[0124] For example, taking K=2 and M=2 as one example, the first CSI reporting configuration information may consist of two sub-configurations of CSI reporting information, and the first CSI-RS resource set in the first CSI-RS resource configuration information related to this CSI reporting information contains K=2 CSI-RS resources. For example, the first sub-configuration may configure the related CSI-RS list in the first CSI reporting configuration information as {CSI-RS#1,CSI-RS#2} and constitute power offset 1, or it may configure {CSI-RS#1,CSI-RS#2} and constitute power offset 2. For example, a terminal device may report one CRI corresponding to both the first and second sub-configurations, where the terminal device may report a CRI corresponding to the first sub-configuration or a CRI corresponding to the second sub-configuration. Which CRI to report may be determined by a predefined method or by a method instructed by the network device, and the present invention is not limited thereto.

[0125] For example, if K=4 and M=2, the first CSI report configuration information may contain two sub-configurations of CSI report information, and the first CSI-RS resource set in the first CSI-RS resource configuration information associated with this CSI report information may contain K=4 CSI-RS resources. For example, the first sub-configuration may configure the associated CSI-RS list as {CSI-RS#1,CSI-RS#2} in the first CSI report configuration information and configure a power offset of 1. The second sub-configuration may configure the associated CSI-RS list as {CSI-RS#3,CSI-RS#4} in the first CSI report configuration information and either not configure a power offset or configure a power offset of 0. For example, the terminal device reports two CRIs corresponding to the first sub-configuration and the second sub-configuration, respectively. For example, a terminal device may report one CRI, which may correspond to a first subconfiguration or a second subconfiguration. Which CRI to report may be determined by a predefined method or by a method instructed by the network device, but the present invention is not limited thereto.

[0126] In some embodiments, each first CSI-RS resource set includes Z CSI-RS resource groups, each of the Z CSI-RS resource groups includes K CSI-RS resources, and the K CSI-RS resources in one of the Z CSI-RS resource groups are used to determine the channel measurement of a subconfiguration among M subconfigurations.

[0127] In some embodiments, Z = M, and Z CSI-RS resource groups correspond one-to-one with M subconfigurations.

[0128] For example, Z is an integer greater than or equal to 1, Z=M, K=16, and for example, the first CSI-RS resource set contains Z CSI-RS resource groups, each of which contains 16 CSI-RS resources.

[0129] For example, in energy-saving scenario 2, taking M=4 (there are four subconfigurations) as an example, four CSI-RS resource groups correspond to four subconfigurations, and the 16 CSI-RS resources in each CSI-RS resource group are used to measure the channel information of one subconfiguration. For example, specific measurement methods may refer to prior art, and the present invention is not limited thereto. For example, a terminal device reports based on the measurement results (details are described in subsequent parts of the specification).

[0130] In some embodiments, each first CSI-RS resource set includes Z CSI-RS resource groups, where Z = M, and each of the Z CSI-RS resource groups corresponds to at least Y group pairing information, one of the Y group pairing information points to Z CSI-RS resources corresponding to the Z CSI-RS resource groups, and one of the Z CSI-RS resources is used to determine the channel measurement of one of the M subconfigurations.

[0131] For example, Y and Z are integers greater than or equal to 1, where Z=M and K=2. For example, the first CSI-RS resource set contains Z CSI-RS resource groups, and each CSI-RS resource group contains 2 CSI-RS resources.

[0132] For example, in energy-saving scenario 2, taking Z=M=3 (there are three subconfigurations) as an example, three CSI-RS resource groups contain six CSI-RS resources. For example, the resources in group 1 correspond to the first subconfiguration (CSI-RS#0, CSI-RS#1), the resources in group 2 correspond to the second subconfiguration (CSI-RS#2, CSI-RS#3), and the resources in group 3 correspond to the third subconfiguration (CSI-RS#4, CSI-RS#5). Additional Y=2 group pairing information is added. For example, group pairing information 1 may be {CSI-RS#0 (corresponding to the first subconfiguration), CSI-RS#2 (corresponding to the second subconfiguration), CSI-RS#4 (corresponding to the third subconfiguration)}, and group pairing information 2 may be {CSI-RS#1 (corresponding to the first subconfiguration), CSI-RS#3 (corresponding to the second subconfiguration), CSI-RS#5 (corresponding to the third subconfiguration)}, and one CSI-RS from each group pairing information is used to measure the channel information of the corresponding subconfiguration. For example, the specific measurement method may refer to the prior art, and the present invention is not limited thereto. The terminal device reports based on the measurement results (details will be described in subsequent parts of the specification).

[0133] In some embodiments, each first CSI-RS resource set includes Z CSI-RS resource groups, each of the Z CSI-RS resource groups includes K CSI-RS resources, each CSI-RS resource in the first of the Z CSI-RS resource groups is used to determine the channel measurement of M subconfigurations, and / or, the K CSI-RS resources in the other CSI-RS resource groups of the Z CSI-RS resource groups are used to determine the channel measurement of subconfigurations of M subconfigurations.

[0134] For example, Z is an integer greater than or equal to 1, where Z = M + 1, M = 6, and K = 2. For example, the first CSI-RS resource set contains Z CSI-RS resource groups, and each CSI-RS resource group contains 16 CSI-RS resources.

[0135] For example, when M=3 and Z=4, the first of the four CSI-RS resource groups corresponds to energy saving scenario 1, and each of the 16 CSI-RS resources in the first CSI-RS resource group provides a channel measurement report corresponding to three subconfigurations. For example, when M=3 and Z=4, the second to fourth CSI-RS resource groups of the four CSI-RS resource groups correspond to energy saving scenario 2, each of the 16 CSI-RS resources in the second CSI-RS resource group provides a channel measurement report corresponding to the first subconfiguration, each of the 16 CSI-RS resources in the third CSI-RS resource group provides a channel measurement report corresponding to the second subconfiguration, and each of the 16 CSI-RS resources in the fourth CSI-RS resource group provides a channel measurement report corresponding to the third subconfiguration. For example, prior art may be referenced for specific measurement methods, and the present invention is not limited thereto. The terminal device will generate a report based on the measurement results (details will be explained in the following sections of the specification).

[0136] In some embodiments, the first CSI-RS resource set includes at least K CSI-RS resources, where each of the K1 CSI-RS resources is used to determine the channel measurement of M sub-components, and / or, one of the M CSI-RS resources other than the K1 CSI-RS resources is used to determine the channel measurement of one of the M sub-components, such that K1 + M = K.

[0137] For example, if M=3 and K1=3, in energy-saving scenario 1, each of the K1 CSI-RS resources corresponds to three subconfigurations, and in energy-saving scenario 2, the i-th resource among the M CSI-RS resources corresponds to the i-th subconfiguration. For example, specific measurement methods may refer to prior art, and the present invention is not limited thereto. The terminal device reports based on the measurement results (details are described in subsequent parts of the specification).

[0138] The above explains how CSI-RS resources for channel measurement of M subconfigurations are determined. The following explains how to instruct terminal devices to report CSI-RS after the CSI-RS resources for channel measurement of M subconfigurations have been determined, specifically, how "the first CSI-RS resource configuration information relates to the first CSI report information corresponding to the M subconfigurations within the first CSI report configuration information."

[0139] In some embodiments, the first CSI reporting configuration information indicates that it reports at least one CSI-RS resource index value reporting quantity information.

[0140] In some embodiments, the amount of information reported for a single CSI-RS resource index value is represented by log(K) bits.

[0141] For example, in energy-saving scenario 1, if K=16, the first CSI-RS resource set includes 16 CSI-RS resources. The terminal device selects the optimal CSI-RS resource based on the larger channel information of the 16 CSI-RS resources and reports the corresponding index (CRI) for the CSI-RS resource. For example, if the third CSI-RS resource is optimal, the third CSI-RS resource may be reported by the corresponding 0011 with log(16)=4 bits.

[0142] In some embodiments, the first CSI reporting configuration information indicates that it does not report CSI-RS resource index value reporting quantity information, and / or reports X CSI-RS resource index value reporting quantity information.

[0143] For example, not reporting CSI-RS resource index value reporting volume information means, for instance, in energy-saving scenario 2, M=4, where four CSI-RS resources each correspond to four subconfigurations, each CSI-RS resource measures channel information for one subconfiguration, the terminal device measures channel status information for all four CSI-RS resources, and reports all CSI information for all four subconfigurations. In this case, reporting CSI-RS resource index value reporting volume information is unnecessary, i.e., CRI is not reported.

[0144] In some embodiments, the X CSI-RS resource index value report information is represented by K bits, where X ≤ K.

[0145] For example, in energy-saving scenario 2, K=M=4, and each of the four CSI-RS resources corresponds to four subconfigurations. The terminal selects and reports X optimal CSI-RSs corresponding to X subconfiguration information based on the large channel information of the four CSI-RS resources. For example, it reports the first and third CSI-RS resources and reports the first and third subconfiguration information using K bits (4 bits), for example, 1010.

[0146] In some embodiments, the first CSI reporting configuration information indicates that it reports at least Z CSI-RS resource index value reporting quantity information, and / or P CSI-RS resource group index value reporting quantity information, and / or P resource index value reporting quantity information for CSI-RS resources in P CSI-RS resource groups.

[0147] In some embodiments, the amount of information for Z CSI-RS resource index values ​​is represented by Zlog(K) bits.

[0148] For example, in energy-saving scenario 2, Z=M=4, each CSI-RS resource group contains 16 CSI-RS resources, and each of the four CSI-RS resource groups corresponds to four sub-configurations. For example, the terminal may measure the channel status information of the four resource groups, select and report the best CSI-RS resource in each group, and report it using Z*log(K)=4*4 bits. For example, the terminal may select and report the first resource in each group, and the amount of CSI-RS resource index value reporting information for all four sub-configurations may be reported as 0001000100010001, reporting the channel measurements for the four sub-configurations.

[0149] In some examples, the reported quantity information for P CSI-RS resource group index values ​​is represented by Z bits, where P ≤ Z.

[0150] For example, in energy-saving scenario 2, Z=M=4, and each of the four CSI-RS resource groups corresponds to four sub-configurations. For example, the terminal measures the channel status information of the four resource groups, for example, measures the first CSI-RS resource in each CSI-RS resource group, and selects and reports the CSI-RS resource group. For example, the selected optimal resources correspond to the second and fourth CSI-RS resource groups. The CSI-RS resource index value reporting information may be represented by Z bits, for example, four bits of 0101.

[0151] In some embodiments, the amount of information for P CSI-RS resource index values ​​is represented by Plog(K)+Z bits.

[0152] For example, in energy-saving scenario 2, Z=M=4, each CSI-RS resource group contains 16 CSI-RS resources, and each of the four CSI-RS resource groups corresponds to four subconfigurations. For example, the terminal device selects P optimal resource groups, e.g., P=2, corresponding to X subconfiguration information, based on the large channel information of the four CSI-RS resources, and reports the groups of the first and third CSI-RS resources. The subconfiguration information for the first and third subconfigurations is reported via 1010 with Z=4 bits, and the optimal CSI-RS resource within each group is reported via 2*log(K), and all CSI information for the two subconfigurations is reported.

[0153] In some embodiments, the first CSI reporting configuration information indicates that it reports at least one CSI-RS resource pairing index value reporting quantity information and / or reports S CSI-RS resource pairing index value reporting quantity information in one CSI-RS resource pairing index value reporting quantity information.

[0154] In some embodiments, the amount of information reported for one CSI-RS resource pairing index value is represented by log(Y) bits.

[0155] For example, if Y=2, the terminal device may measure the channel status information of all CSI-RS resources in the two group pairs, select and report the optimal group pair, and report it as log(Y=2)=1 bit. For example, if the first group pair is selected and reported, it is determined by 0 that the resources used for channel measurement reporting of the three sub-configurations are {CSI-RS#0,CSI-RS#2,CSI-RS#4}, and all CSI information for the three sub-configurations is reported.

[0156] In some embodiments, S CSI-RS resource index value reporting information is represented by M bits, where S ≤ M.

[0157] For example, in energy-saving scenario 2, Y=2, the terminal device may measure the channel status information of all CSI-RS resources in the two group pairs, select and report the optimal group pair, and report it with log(Y=2)=1 bit. For example, if the first group pair is selected and reported, bit "0" determines that the resources used for channel measurement reporting of the three sub-configurations are {CSI-RS#0, CSI-RS#2, CSI-RS#4}, and further, S sub-configuration information corresponding to S optimal resources from the reported group pairs is selected, and M bits, for example 011, represent the selection and reporting of CSI-RS#2, CSI-RS#4, indicating all CSI information for the two sub-configurations after the report.

[0158] In some embodiments, the first CSI reporting configuration information indicates that it reports at least one CSI-RS resource pairing index value reporting quantity information and / or reports 1+J CSI-RS index values.

[0159] In some embodiments, the amount of information reported for a single CSI-RS resource index value is represented by log(K1) bits.

[0160] For example, a terminal device may measure the channel status information of all K1 CSI-RS resources, select the optimal CSI-RS resource from among the K1 resources, for example, K1=4, and report it using log(4) = 2 bits. For example, selecting and reporting the first CSI-RS resource may be reported with bit "00". It is also necessary to report all of the subsequent M CSI-RS resources.

[0161] In some embodiments, the amount of information reported for 1+J CSI-RS resource index values ​​is represented by log(K1)+M bits, where J ≤ M.

[0162] For example, a terminal device measures the channel status information of all K1 CSI-RS resources and M CSI-RS resources, and selects the optimal J CSI-RS resources from the M CSI-RS resources, for example, J=2. After the optimal resources from the K1 CSI-RS resources are reported using the log(K1) method described above, the optimal J CSI-RS resources (for example, J=2) must be further indicated by M bits, where bit "011" represents CSI information for selecting and reporting the second and third subconfigurations.

[0163] The above describes a method for determining the M sub-configuration CSI-RS resources for channel measurement, and a method for instructing a terminal device to perform CSI-RS reporting after determining the M sub-configuration CSI-RS resources.

[0164] The following examples will be explained while referring to the specific operations of the terminal device.

[0165] For example, if "each first CSI-RS resource set contains K CSI-RS resources, and each of the K CSI-RS resources is used to determine channel measurements for M sub-configurations" and "the first CSI reporting configuration information indicates at least one CSI-RS resource index value reporting amount information, which is indicated by log(K) bits", then the operation on the terminal device side includes, but is not limited to, the following steps:

[0166] (1) Step 1: The terminal device receives first CSI-RS resource configuration information for channel measurement. Here, the first CSI-RS resource configuration information includes one first CSI-RS resource set, and one first CSI-RS resource set includes K=16 CSI-RS resources.

[0167] (2) Step 2: The first CSI report configuration information includes the first CSI report information for M=3 subconfigurations, where M=3 represents three subconfiguration information for 32 ports, 16 ports, and 12 ports.

[0168] (a) Step 2-1: The port configuration for the three subconfigurations can be done as follows:

[0169] i. For example, the three instruction pieces are "nrofport1" = 32, "nrofport2" = 16, and "nrofport2" = 12, and / or ii. The three instruction pieces are "N1, N2_L1" = (4,4), "N1, N2_L2" = (4,2), and "N1, N2_L3" = (3,4), and / or iii. Port instructions for the remaining subconfigurations can be provided by the number of ports in subconfiguration #0 or by a bitmap obtained by dividing the number of ports by 2.

[0170] 1. For example, port instruction can be done by specifying "N1, N2" = (4,4), such as port instruction for 32.

[0171] 2.16 A port can be represented by a 32-bitmap. For example, 1100110011001100110011001100 represents the instruction information for port 16.

[0172] 3.12 ports can also be represented by a 32-bitmap. For example, 11001000110010001100100011001000 represents the instruction information for port 12.

[0173] 4. Since the first 16 bits and the last 16 bits indicate different polarization directions and the selected antenna elements must match, port indication may be done with an additional 16 bitmap.

[0174] (a) 16 ports can also be represented by a 16-bitmap. For example, 1100110011001100 indicates the information for 16 ports.

[0175] (b) 12 ports can also be represented by a 16-bitmap. For example, 1100100011001000 represents the instruction information for 12 ports.

[0176] (3) Step 3: The 16 CSI-RS resources in the first CSI-RS resource set are associated with M=3 subconfigurations in the first CSI reporting configuration information.

[0177] (4) Step 4: The terminal device selects the optimal resource based on the large channel information of the 16 CSI-RS resources and reports the CRI. For example, it may select the third CSI-RS resource and report the third CSI-RS resource with log(16)=4 bits 0011.

[0178] (5) Step 5: The terminal device measures the channel status information in the three subconfigurations based on the third CSI-RS resource and the subconfiguration information of M=3, and reports all CSI information for the three subconfigurations.

[0179] For example, if "each first CSI-RS resource set contains K CSI-RS resources, K=M, and one of the K CSI-RS resources is used to determine the channel measurement of one of the M subconfigurations" and "the first CSI reporting configuration information indicates that it does not report CSI-RS resource index value reporting quantity information, and / or reports X CSI-RS resource index value reporting quantity information," then the operation on the terminal device side includes, but is not limited to, the following steps:

[0180] (1) Step 1: The terminal device receives first CSI-RS resource configuration information for channel measurement. Here, the first CSI-RS resource configuration information includes one first CSI-RS resource set, and one first CSI-RS resource set includes K=4 CSI-RS resources. (2) Step 2: The first CSI report configuration information includes first CSI report information with M=4 subconfigurations. Here, M=4 represents different energy-saving subconfiguration information on the same port, for example, a 32 physical antenna configuration, a 16 physical antenna configuration, a 12 physical antenna configuration, and an 8 physical antenna configuration on 4 ports (this physical antenna configuration is transparent to the terminal side).

[0181] (3) Step 3: The four CSI-RS resources in the first CSI-RS resource set are used one-to-one for M=4 sub-configurations in the first CSI reporting configuration information, for example, the first CSI-RS resources are used for measuring a 64 physical antenna configuration on 4 ports.

[0182] (a) Step 3-1: Here, the port configuration of the four subconfigurations may be as follows: i. The number of ports of the four subconfigurations indicated by the four instruction pieces are equal, for example, "nrofport1" = "nrofport2" = "nrofport3" = "nrofport4" = 32.

[0183] ii. The port configurations in the reported configurations of the four subconfigurations indicated by the four instruction pieces are identical, for example, "N1, N2_L1" = "N1, N2_L2" = "N1, N2_L3" = "N1, N2_L4" = (4,4).

[0184] iii. Optionally, all resource port configurations may be done in a single instruction message, for example, by configuring "nrofports" within the resource setting.

[0185] (4) Step 4-1: The terminal device measures the channel status information of the four CSI-RS resources and reports all CSI information for the four sub-configurations. In this case, reporting of CRI is not required.

[0186] (5) Step 4-2: The terminal device selects and reports X optimal resources corresponding to X sub-configuration information based on the large-size channel information of the four resources. For example, it may report the first and third resources, and via K=4 bit 1010, it may report the first and third CSI-RS resources, and report all CSI information for the two sub-configurations.

[0187] For example, if "each first CSI-RS resource set includes Z CSI-RS resource groups, and each of the Z CSI-RS resource groups includes K CSI-RS resources, where K CSI-RS resources in one of the Z CSI-RS resource groups are used to determine the channel measurement of one of the M subconfigurations" and "the first CSI reporting configuration information reports at least Z CSI-RS resource index value reporting information, and / or reports index value reporting information for P CSI-RS resource groups, and / or indicates P resource index value reporting information for CSI-RS resources in the P CSI-RS resource groups," then the operation on the terminal device side includes, but is not limited to, the following steps.

[0188] (1) Step 1: The terminal device receives first CSI-RS resource configuration information for channel measurement. Here, the first CSI-RS resource configuration information includes one first CSI-RS resource set, one first CSI-RS resource set includes Z=4 CSI-RS resource groups, and one CSI-RS resource group includes K=16 CSI-RS resources. Thus, it includes a total of 64 sub-CSI-RS resource information entries.

[0189] (2) Step 2: The first CSI report configuration information includes the first CSI report information for M=4 subconfigurations, where M=4 represents different energy-saving subconfiguration information for the same port, for example, 32 physical antenna configurations, 16 physical antenna configurations, 12 physical antenna configurations, and 8 physical antenna configurations for 4 ports (this physical antenna configuration is transparent to the terminal side).

[0190] (3) Step 3: Each of the four resource groups in the first CSI-RS resource set is used one-to-one for M=4 subconfigurations in the first CSI reporting configuration information. For example, the first CSI-RS resource group is used to measure 64 physical antenna configurations across 4 ports.

[0191] (a) Step 3-1: Here the port configurations of the four subconfigurations may be as follows: i. The number of ports in all resource configurations of the four resource groups corresponding to the four subconfigurations indicated by the four instruction pieces is equal, for example, "nrofport1" = "nrofport2" = "nrofport3" = "nrofport4" = 32.

[0192] ii. The port configurations of the four subconfigurations indicated by the four instruction pieces are identical, for example, "N1, N2_L1" = "N1, N2_L2" = "N1, N2_L3" = "N1, N2_L4" = (4,4).

[0193] iii. Optionally, all resource port configurations can be configured with a single instruction. For example, configure "nrofports" within the resource setting and / or report only one N1 and N2 piece of information for all subconfigurations in the configuration.

[0194] (4) Step 4-1: The terminal device may measure the channel status information of the four resource groups, select and report the optimal resource within each group, and report it in Z*log(K)=4*4 bits. For example, it may select the first resource within each group, report the channel measurements of the four sub-configurations as 0001000100010001, and report all CSI information for the four sub-configurations.

[0195] (5) Step 4-2: Further reporting overhead may be saved in a predefined manner, for example, by ensuring that the resource index values ​​for each selected group are identical. For example, select and report the first resource within each group, report the channel measurements for the four sub-components with log(K) bits such as 0001, and report all CSI information for the four sub-components.

[0196] (6) Step 4-2: The terminal device may select and report P optimal resource groups corresponding to P sub-configuration information based on the channel information of the larger resources of the four resource groups, for example, by reporting the first and third resource groups, reporting the first and third sub-configuration information using 1010 with Z=4 bits, reporting the optimal CSI-RS resource within each group using 2*log(K), and reporting all CSI information for the two sub-configurations.

[0197] (7) Step 4-3: The terminal device selects and reports the P best resource groups corresponding to the P subconfiguration information based on the large channel information within the four resource groups, for example, reporting the 1st and 3rd resource groups and reporting the 1st and 3rd subconfiguration information using 1010 with Z=4 bits. Next, it reports the best CSI-RS resource within each group in log(K) using a predefined method, such as the resource index values ​​of each group being the same, and reports all CSI information for the two subconfigurations.

[0198] For example, if "each first CSI-RS resource set includes Z CSI-RS resource groups, where Z=M, and each of the Z CSI-RS resource groups corresponds to at least Y group pairing information, one of the Y group pairing information points to Z CSI-RS resources corresponding to the Z CSI-RS resource groups, and one of the Z CSI-RS resources is used to determine channel measurements for one of the M subconfigurations" and "the first CSI reporting configuration information reports at least one CSI-RS resource pairing index value reporting quantity information, and / or reports S CSI-RS resource index value reporting quantity information for the corresponding CSI-RS resources in one CSI-RS resource pair," then the operation on the terminal device side includes, but is not limited to, the following steps.

[0199] (1) Step 1-1: The terminal device receives first CSI-RS resource configuration information for channel measurement. Here, the first CSI-RS resource configuration information includes one first CSI-RS resource set, one first CSI-RS resource set includes Z=3 CSI-RS resource groups, and one CSI-RS resource group includes K=2 CSI-RS resources, so it includes a total of 6 CSI-RS resource information entries. The resources of group 1 are (CSI-RS#0, CSI-RS#1), the resources of group 2 are (CSI-RS#2, CSI-RS#3), and the resources of group 3 are (CSI-RS#4, CSI-RS#5).

[0200] (2) Step 1-2: Add two additional Y group pairing information entries. For example, group pairing information 1 may be {CSI-RS#0,CSI-RS#2,CSI-RS#4}, and group pairing information 2 may be {CSI-RS#1,CSI-RS#3,CSI-RS#5}.

[0201] (a) Optionally, the number of group pairing information entries may consist of higher-level information or a predefined scheme.

[0202] (3) Step 2: The first CSI report configuration information includes the first CSI report information for M=3 subconfigurations, where M=3 represents different energy-saving subconfiguration information for the same port, for example, a 32 physical antenna configuration, a 16 physical antenna configuration, and a 12 physical antenna configuration for 4 ports (this physical antenna configuration is transparent to the terminal side).

[0203] (4) Step 3: The resources in each of the three resource groups within the first CSI-RS resource set are used one-to-one with M=4 sub-configuration information in the first CSI reporting configuration information. For example, the first CSI-RS resource group is used to measure a 32 physical antenna configuration with 4 ports.

[0204] (a) Step 3-1: Here, the port configuration of the three subconfigurations can be done as follows: i. The number of ports in all resource configuration information for the four groups of resources corresponding to the three subconfigurations indicated by the three instruction information are equal, for example, "nrofport1" = "nrofport2" = "nrofport3" = 32.

[0205] ii. The port configurations in the reporting settings for the three subconfigurations indicated by the three instruction pieces are identical, for example, "N1, N2_L1" = "N1, N2_L2" = "N1, N2_L3" = (4,4).

[0206] iii. Optionally, all resource port configurations may be performed with a single instruction, for example, by configuring "nrofports" within the resource setting and / or by reporting only one N1,N2 piece of information for all subconfigurations in the configuration.

[0207] (5) Step 4-1: The terminal device may measure the channel status information of all resources in the two group pairs, select and report the optimal resource group pairing information, and report it by log(Y=2)=1 bit. For example, if the first group pairing information is selected and reported, bit "0" may determine that the resources used for channel measurement reporting of the three sub-configurations are {CSI-RS#0, CSI-RS#2, CSI-RS#4}, and report all CSI information for the three sub-configurations.

[0208] (6) Step 4-2: The terminal device may measure the channel status information of all resources in the two group pairs, select and report the optimal resource group pairing information, and report it by log(Y=2)=1 bit. For example, if it chooses to report the first group pairing information, bit "0" determines that the resources used for reporting the channel measurement of the three sub-configurations are {CSI-RS#0, CSI-RS#2, CSI-RS#4}, and then selects that S optimal resource groups in the reporting pair correspond to S sub-configuration information, for example S=2, and further, log(M) bit, for example 011, indicates that it has selected and reported CSI-RS#2, CSI-RS#4, which represent all CSI information of the two sub-configurations after reporting.

[0209] For example, if "each first CSI-RS resource set includes Z CSI-RS resource groups, and each of the Z CSI-RS resource groups includes K CSI-RS resources, where each CSI-RS resource in the first CSI-RS resource group among the Z CSI-RS resource groups is used to determine channel measurements for M subconfigurations, and / or, K CSI-RS resources in a set of other CSI-RS resource groups other than the first CSI-RS resource group among the Z CSI-RS resource groups are used to determine channel measurements for one of the M subconfigurations," then the operation on the terminal side includes, but is not limited to, the following steps:

[0210] (1) Step 1: The terminal device receives first CSI-RS resource configuration information for channel measurement. Here, the first CSI-RS resource configuration information includes one first CSI-RS resource set, one first CSI-RS resource set includes Z=4 CSI-RS resource groups, and one CSI-RS resource group includes K=16 CSI-RS resources, so it includes a total of 64 sub-resource information.

[0211] (2) Step 2-1: The first CSI report configuration information includes the first CSI report information of M=3 sub-configurations, where each of the K CSI-RS resources in the first group corresponds to the channel measurement report of the three sub-configurations. For example, in energy saving scenario 1, the number of ports in the three sub-configurations are different, for example, they correspond to 32 ports, 16 ports, and 12 ports, respectively. The K resources in the first group can be configured with three sub-configuration port configurations as follows:

[0212] i. For example, "nrofport1" = 32, "nrofport2" = 16, "nrofport2" = 12, and / or, ii. Port specifications for the remaining subconfigurations can be made using the number of ports in subconfiguration #0 or a bitmap obtained by dividing the number of ports by 2.

[0213] 1. For example, port 32 can be specified by "N1, N2" = (4,4).

[0214] 2.16 A port can be represented by a 32-bitmap. For example, 1100110011001100110011001100 represents port designation information for port 16.

[0215] 3.12 A port can also be represented by a 32-bitmap. For example, 11001000110010001100100011001000 represents port designation information for port 12.

[0216] 4. Since the first 16 bits and the last 16 bits represent different polarization directions and the selected antenna elements match, port indication can be done with an additional 16 bitmap.

[0217] (a) 16 ports can be represented by a 16-bitmap. For example, 1100110011001100 represents port designation information for 16 ports.

[0218] (b) A 12-port port can also be represented by a 16-bitmap. For example, 1100100011001000 represents port designation information for a 12-port port.

[0219] (3) Step 2-2: The first CSI report configuration information includes the first CSI report information for M=3 subconfigurations. Here, the second group CSI-RS resources to the fourth group CSI-RS resources correspond one-to-one with the first to third subconfigurations, respectively. The first to third subconfigurations have the same number of ports and represent different energy-saving subconfiguration information for the same port, for example, a 32 physical antenna configuration, a 16 physical antenna configuration, and a 12 physical antenna configuration for 4 ports.

[0220] i. The port configuration for the four subconfigurations may be as follows: 1. The number of ports for all resource configuration information in the four resource groups corresponding to the three subconfigurations is equal, for example, "nrofport1" = "nrofport2" = "nrofport3" = 32.

[0221] 2. The port configurations for reporting settings of the three sub-configurations are identical, for example, "N1, N2_L1" = "N1, N2_L2" = "N1, N2_L3" = (4,4).

[0222] 3. Optionally, all resources can be configured using a single port configuration entry. For example, configure "nrofports" within the resource settings and / or configure only one N1 and N2 entry for all sub-configurations in the reporting settings.

[0223] 4. Optionally, the port configuration information for each group can be provided using three configuration details.

[0224] (4) Step 4-1: The terminal device measures the channel status information of the four groups of resources, selects and reports the best resource within each group, and may report it in Z*log(K)=4*4 bits. For example, to measure the channel, 0001000100010001 is used to report the first resource in each group.

[0225] (a) In the first group, select the first resource to report all CSI information for the three sub-configurations, namely the CSI information for port 32, port 16, and port 12.

[0226] (b) The second group reports the first resource in order to report the CSI information for the first subconfiguration, i.e., the CSI information for the 32 physical antennas on port 4.

[0227] (c) In the third group, the first resource is reported in order to report the CSI information for the second subconfiguration, i.e., the CSI information for the 16 physical antennas on port 4.

[0228] (d) In the fourth group, report the first resource to report the CSI information for the third subconfiguration, i.e., the CSI information for the 12 physical antennas on port 4.

[0229] (5) Step 4-2: Further reporting overhead may be saved by following a predefined method such that the resource index values ​​for each selected group are identical. For example, the first resource in each group may be selected and reported, and the channel measurements for the four sub-configurations may be reported via a log(K) bit such as 0001.

[0230] For example, if "the first CSI-RS resource set includes at least K CSI-RS resources, where each of the K1 CSI-RS resources is used to determine channel measurements for M subconfigurations, and / or one of the M CSI-RS resources other than the K1 CSI-RS resources is used to determine channel measurements for one of the M subconfigurations, where K1 + M = K" and "the first CSI reporting configuration information reports at least one CSI-RS resource pairing index value reporting quantity information, and / or indicates a CSI-RS index value report of 1 + J", then the operation on the terminal device side includes, but is not limited to, the following steps.

[0231] (1) Step 1: The terminal device receives first CSI-RS resource configuration information for channel measurement. Here, the first CSI-RS resource configuration information includes one first CSI-RS resource set, and one first CSI-RS resource set includes K=6 CSI-RS resources, which can be divided into the following two groups of resources.

[0232] (a) Resources #0 to K1-1: Correspond to energy saving scenario 1, with K1 corresponding to 3 CSI-RS resources, and each resource corresponding to 3 sub-configurations.

[0233] (b) Resources #K1~K-1: Correspond to energy saving scenario 2, M=3 CSI-RS resources, and the i-th resource among the M CSI-RS resources corresponds to the i-th sub-configuration information.

[0234] (2) Step 2-1: The first CSI report configuration information includes the first CSI report information for M=3 sub-configurations, and each resource of the first K1 resource corresponds to the channel measurement report of all three sub-configurations. That is, in the energy saving scenario 1, the number of ports of the three sub-configurations are different, for example, 32 ports, 16 ports and 12 ports. The port configuration of the three sub-configurations may be as follows: i. For example, "nrofport1"=32, "nrofport2"=16, "nrofport2"=12, and / or ii. Port specifications for the remaining subconfigurations can be made using the number of ports in subconfiguration #0 or a bitmap obtained by dividing the number of ports by 2.

[0235] 1. For example, for 32 ports, port designation can be done using "N1, N2" = (4,4).

[0236] 2.16 A port can be represented by a 32-bitmap. For example, 1100110011001100110011001100 represents port designation information for port 16.

[0237] 3.12 ports can also be specified using a 32-bitmap. For example, 11001000110010001100100011001000 represents a port specification for port 12.

[0238] 4. The first 16 bits and the last 16 bits represent different polarization directions, and the selected antenna elements must match, so the 16 bitmap can be used to further specify the port.

[0239] (a) 16 ports can be represented by a 16-bitmap. For example, 1100110011001100 represents port designation information for 16 ports.

[0240] (b) A 12-port can also be represented by a 16-bitmap. For example, 1100100011001000 represents port designation information for a 12-port.

[0241] (3) Step 2-2: The first CSI reporting configuration information includes the first CSI reporting information for M=3 subconfigurations, and each of the last M resources in the first CSI-RS resource configuration is used one-to-one with the three subconfigurations in the first CSI reporting configuration information, so the number of ports in the last three subconfigurations is the same, for example, representing different energy-saving subconfiguration information for the same port, for example, a 32 physical antenna configuration, a 16 physical antenna configuration, and a 12 physical antenna configuration for 4 ports.

[0242] i. Here, the port configurations for the three subconfigurations may be as follows:

[0243] 1. For example, "nrofport1" = "nrofport2" = "nrofport3" = 32.

[0244] 2. In the reporting settings for the three sub-configurations, the port configuration must be identical, for example, "N1, N2_L1" = "N1, N2_L2" = "N1, N2_L3" = (4,4).

[0245] 3. Optionally, all resources can be configured using a single port configuration. For example, you can configure "nrofports" within the resource setting and / or configure only one N1 and N2 piece of information for all sub-configurations in the reporting settings.

[0246] 4. Optionally, the port configuration information for each group can be derived from three configuration options.

[0247] (4) Step 4-1: The terminal may measure the channel status information of all resources, select the best resource from the first K1 resource and report it as log(3)=2 bits, and it must report this for all subsequent M resources, and it is predefined that, for example, 2 bits is "00" and means the following:

[0248] (a) Select the first resource within the first K1 resource and report all CSI information for the three sub-configurations, namely the CSI information for port 32, port 16, and port 12.

[0249] (b) Select all corresponding subconfigurations of the last M resources, for example, CSI information for 32 physical antennas, 16 physical antennas, and 12 physical antennas in 4 ports.

[0250] (4) Step 4-2: The terminal device measures the channel status information of all resources, selects and reports the best resource within the first K1 resource, and may report it using log(3) = 2 bits. It also selects resources corresponding to sub-configurations within the last M resources, for example, selecting two (J=2), and 3 bits, for example, bit "011", indicates that the CSI information of the second and third sub-configurations has been selected and reported.

[0251] The above explains, with reference to examples, how terminal equipment performs channel measurement. For example, in an actual CSI configuration, additional CSI-RS resource settings may be configured, primarily for interference measurement (IM), and the CSI-RS resources in the corresponding configuration set are CSI-IM and / or CSI-RS.

[0252] The specific explanation is as follows:

[0253] In some embodiments, the terminal device further receives second CSI resource configuration information. The second CSI resource configuration information constitutes at least one second CSI-RS resource set, each second CSI-RS resource set containing K CSI-IM and / or NZP CSI-RS resources, and each of the K CSI-IM and / or NZP CSI-RS resources is used to determine interference measurements of M sub-configurations.

[0254] In some embodiments, the terminal device further receives second CSI resource configuration information. The second CSI resource configuration information constitutes at least one second CSI-RS resource set, each second CSI-RS resource set containing M*K CSI-IM and / or NZP CSI-RS resources, where each of the K CSI-IM and / or NZP CSI-RS resources is used to determine the interference measurement of the subconfiguration.

[0255] In some embodiments, the terminal device further receives second CSI resource configuration information. The second CSI resource configuration information constitutes at least one second CSI-RS resource set, each second CSI-RS resource set containing K CSI-IM and / or NZP CSI-RS resources, and each of the K CSI-IM and / or NZP CSI-RS resources is used to determine the interference measurement of the subconfiguration.

[0256] In some embodiments, the terminal device further receives second CSI resource configuration information. The second CSI resource configuration information constitutes at least one second CSI-RS resource set, each second CSI-RS resource set including CSI-IM and / or NZP CSI-RS resources, the CSI-IM and / or NZP CSI-RS resources being used to determine interference measurements of M sub-configurations.

[0257] In some embodiments, the terminal device further receives second CSI resource configuration information. The second CSI resource configuration information constitutes at least one second CSI-RS resource set, each second CSI-RS resource set containing Z*K CSI-IM and / or NZP CSI-RS resources, where each of the K CSI-IM and / or NZP CSI-RS resources is used to determine the interference measurement of the subconfiguration.

[0258] In some embodiments, the terminal device further receives second CSI resource configuration information. The second CSI resource configuration information constitutes at least one second CSI-RS resource set, each second CSI-RS resource set including CSI-IM and / or NZP CSI-RS resources, which are used to determine interference measurements of M sub-configurations.

[0259] In some embodiments, the terminal device further receives second CSI resource configuration information. The second CSI resource configuration information constitutes at least one second CSI-RS resource set, each second CSI-RS resource set containing K CSI-IM and / or NZP CSI-RS resources, the CSI-IM and / or NZP CSI-RS resources being used to determine interference measurements of M sub-configurations.

[0260] In some embodiments, the terminal device further receives second CSI resource configuration information. The second CSI resource configuration information constitutes at least one second CSI-RS resource set, each second CSI-RS resource set containing Z CSI-IM and / or NZP CSI-RS resources, each CSI-IM and / or NZP CSI-RS resource used to determine the interference measurement of the subconfiguration.

[0261] For example, in energy-saving scenario 1, if K CSI-RS resources are configured within each first CSI-RS resource set in the resource configuration for channel measurement, and all of them are used for channel measurement of M sub-configurations, then the CSI-RS resource configuration for interference measurement is performed in the following two ways: (1) K CSI-IMs are configured within a resource set for interference measurement (second CSI-RS resource set), corresponding one-to-one with K CSI-RSs for channel measurement, and each CSI-IM may be used for adjacent cell interference measurement under all subconfigurations. (2) M*K CSI-IMs are configured within a resource set for interference measurement (second CSI-RS resource set), corresponding to K CSI-RSs for channel measurement, and each CSI-IM may be used for adjacent cell interference measurement under one subconfiguration.

[0262] For example, in energy-saving scenario 2, if each first CSI-RS resource set in the resource configuration for channel measurement has K CSI-RS resources, and each CSI-RS resource is used for channel measurement of one sub-configuration, i.e., M=K, then the CSI-RS resource configuration for interference measurement can be performed in the following two ways: (1) K CSI-IMs are configured within a resource set for interference measurement (second CSI-RS resource set), corresponding one-to-one with K CSI-RSs for channel measurement, and each CSI-IM may be used for adjacent cell interference measurement under one subconfiguration. (2) One CSI-IM is configured within a resource set for interference measurement (second CSI-RS resource set), and each CSI-IM may be used for adjacent cell interference measurement under all M sub-configurations.

[0263] For example, in energy-saving scenario 2, if each first CSI-RS resource set in the resource configuration for channel measurement has Z*K resources, and each resource in one CSI-RS resource set is used for channel measurement of one sub-configuration, i.e., M=Z, then the configuration of CSI-RS resources for interference measurement can be done in one of the following ways:

[0264] (1) Within the set of resources for interference measurement, there are Z*K CSI-IMs associated with Z*K CSI-RSs for channel measurement, and each CSI-IM may be used for adjacent cell interference measurement in one sub-configuration. (2) Within the set of resources for interference measurement (second CSI-RS resource set), one CSI-IM is configured, and each CSI-IM may be used for adjacent cell interference measurement in all M subconfigurations. (3) Within the set of resources for interference measurement (second CSI-RS resource set), K CSI-IMs are configured, each CSI-IM being associated with K CSI-RSs for channel measurement, and each CSI-IM may be used for adjacent cell interference measurement in all M sub-configurations.

[0265] In some embodiments, "energy-saving mode" may be replaced with power-saving mode, sleep mode, abnormal mode, deactivation mode, a mode after the network device adjusts the ratio of Energy Per Resource Element (EPRE) of PDSCH to Energy Per Resource Element (EPRE), a mode after the network device adjusts the CSI-RS resource configuration, a mode after the network device adjusts the CSI reporting configuration, a mode after the spatial domain / energy domain elements are adjusted, and the present invention is not limited to these.
