Description

Resource indication method and device Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] As a crucial component of new global infrastructure, 5G communication networks have experienced rapid development in recent years. As networks expand, operators' energy consumption continues to rise. For example, data released by China's Ministry of Industry and Information Technology indicates that energy consumption will increase by approximately 80% between 2015 and 2022.

[0003] With the development of 5G and the large-scale commercial use of 5G active antenna units (AAUs), energy consumption will increase exponentially compared to the remote radio units (RRUs) used primarily in 3G and 4G, due to the higher power consumption of AAUs. 5G defines three major service types: enhanced mobile broadband (eMBB), massive machine type of communication (mMTC), and ultra-reliable low-latency communication (URLLC). This will lead to an increase in bursty small packet traffic and 24 / 7 base station operation. The average daily energy consumption of 5G sites will be more than double that of 4G.

[0004] In the 5G era, 3GPP has introduced key technologies such as Massive MIMO and increased RF bandwidth. 5G supports higher data rates and greater data traffic, requiring more transmission bandwidth. High-frequency bands will be the primary frequency band for future 5G expansion. However, the transmission characteristics of high-frequency bands limit site coverage, leading to denser deployment of 5G sites. The increased energy consumption will also place significant pressure on operators' operating costs. Therefore, network energy conservation is crucial for reducing operating costs, and energy conservation in 5G networks is a pressing issue.

[0005] To achieve energy conservation, network devices can implement energy conservation in the time, frequency, spatial, and / or energy domains, depending on network load. For example, in the spatial and energy domains, network devices can power down some antennas when the load is low. In the time domain, network devices can implement cell-level discontinuous transmission / reception technology, which prevents network devices from transmitting and / or receiving signals during certain sleep periods.

[0006] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0007] Summary of the Invention

[0008] The inventors discovered that in the prior art, network devices typically do not adjust network antenna configurations, and Channel State Information Reference Signal (CSI-RS) resources are configured via semi-static signaling. Terminal devices can assume that CSI-RS resources are mapped based on semi-static CSI-RS resource configuration information and perform CSI measurements based on the semi-static CSI-RS resources.

[0009] However, in some scenarios of wireless communication applications (such as energy-saving mode), network equipment needs to adjust the antenna configuration used to serve terminal devices based on the real-time needs of network services, such as the number of antenna elements, antenna ports, etc. The antenna configuration may cause changes in the CSI-RS port, which in turn causes changes in the CSI-RS resources, ultimately affecting the transmission and reception of CSI-RS. In the prior art, CSI-RS is configured based on semi-static signaling. The terminal device is unaware of the changes in CSI-RS resources caused by changes in antenna configuration, which may cause the terminal device to incorrectly receive CSI-RS.

[0010] To address at least one of the above problems, embodiments of the present application provide a resource indication method and apparatus.

[0017] According to another aspect of an embodiment of the present application, a resource indication method is provided, including:

[0018] The network device sends first information to the terminal device, where the first information is used to configure at least K resources and / or M ports, where K≥1 and M≥1;

[0020] According to another aspect of an embodiment of the present application, a resource indication device is provided, including:

[0021] A first sending unit, configured to send first information to a terminal device, where the first information is used to configure at least K resources and / or M ports, where K≥1 and M≥1;

[0022] A second sending unit sends second information to the terminal device, where the second information is at least used to indicate / trigger / activate K1 resources among the K resources and / or M1 ports among the M ports, where 1≤K1≤K, 1≤M1≤M.

[0023] According to another aspect of an embodiment of the present application, a communication system is provided, including:

[0024] A network device, wherein the first information is used to configure at least K resources and / or M ports, where K≥1 and M≥1, to a terminal device; and wherein the second information is used to indicate / trigger / activate at least K1 resources of the K resources and / or M1 ports of the M ports, where 1≤K1≤K and 1≤M1≤M, to the terminal device.

[0025] A terminal device receives the first information and / or the second information.

[0026] One of the beneficial effects of the embodiments of the present application is that even when resources change in some scenarios of wireless communication applications (such as energy-saving mode), the network device sends resource / port indication / trigger / activation information to the terminal device, which can indicate the resources in a timely and accurate manner, so that the terminal device can correctly receive the signal (such as CSI-RS) based on the indication information, thereby improving frequency resource utilization and enhancing energy-saving gains.

[0054] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0055] FIG1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a situation using a terminal device and a network device as an example. As shown in FIG1 , a communication system 100 may include a network device 101 and terminal devices 102 and 103. For simplicity, FIG1 illustrates only two terminal devices and one network device as an example, but the embodiments of the present application are not limited thereto.

[0056] In the embodiment of the present application, existing services or future services can be transmitted between the network device 101 and the terminal devices 102 and 103. For example, these services may include but are not limited to: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0057] It is worth noting that FIG1 shows that both terminal devices 102 and 103 are within the coverage range of network device 101, but the present application is not limited thereto. Both terminal devices 102 and 103 may not be within the coverage range of network device 101, or one terminal device 102 may be within the coverage range of network device 101 while the other terminal device 103 is outside the coverage range of network device 101.

[0058] In the embodiments of the present application, the high-layer signaling may be, for example, radio resource control (RRC) signaling; for example, an RRC message, including, for example, an MIB, system information, or a dedicated RRC message; or an RRC information element (RRC IE). The high-layer signaling may also be, for example, MAC (Medium Access Control) signaling; or a MAC control element (MAC CE). However, the present application is not limited thereto.

[0059] In mobile communication systems, terminal devices typically measure CSI (channel state information) based on instructions and configuration from network devices and then report the measured CSI to the network devices. When scheduling the terminal device, the network device can refer to this CSI to schedule the terminal device for transmission using the appropriate physical resources and transmission method. Different terminal devices may experience different physical channel conditions. Using a CSI feedback mechanism can effectively utilize physical resources, thereby improving overall network transmission efficiency.

[0060] In the NR CSI feedback mechanism, the terminal device primarily measures and reports reference signals from the network device based on the CSI configuration. Reference signals include the Channel State Information Reference Signal (CSI-RS) and Synchronization Signal Block (SSB). The NR CSI configuration primarily includes: the resource configuration for CSI measurement configured by the network device for the terminal device (referred to as the CSI-RS resource configuration), and the reporting configuration that the network device uses to configure the terminal device for reporting (referred to as the CSI reporting configuration).

[0061] For example, CSI-RS resource configuration primarily includes the time-frequency and spatial resources of the CSI-RS resource, as well as the necessary parameters for generating the RS sequence. In short, based on the CSI-RS resource configuration, the terminal device accurately determines the RS sequence of the network device and its specific time-frequency and spatial resource location, allowing it to receive the sequence at the corresponding location and perform signal processing on the received sequence using the locally generated sequence as a reference to accurately estimate the channel. The specific RS sequence generation method can be referenced in related technologies and will not be explained in detail here.

[0062] The embodiment of the present application will explain the CSI-RS resource configuration. For each CSI-RS resource time-frequency position, the network device determines the following parameters in the CSI-RS-ResourceMapping, as shown in Table 1 below.

[0063] Table 1

[0064] As shown in Table 1, firstOFDMSymbolInTimeDomain and firstOFDMSymbolInTimeDomain2 are used to determine the position of the CSI-RS resource in the time domain. Currently, NR supports occupying 1, 2 or 4 orthogonal frequency division multiplexing (OFDM) symbols; the frequencyDomainAllocation parameter is used to determine the position of the CSI-RS resource in the frequency domain; the nrofPorts parameter is used to determine the number of CSI-RS ports. Currently, NR supports configurations of 1, 2, 4, 8, 12, 16, 24 and 32 ports; the cdm-Type parameter is used to determine the code division multiplexing (CDM) type of the CSI-RS resource. Currently, NR supports three patterns: CDM-2, CDM-4 and CDM-8.

[0065] Figure 2 shows a schematic diagram of a CDM pattern. Taking CDM-4 as an example, this pattern includes four ports, each occupying all resource elements (REs) within the pattern. Ports are distinguished by different orthogonal cover codes. The REs occupied by a CDM pattern constitute a CDM group, with each CDM group containing two, four, or eight ports. This allows multiple CSI-RS ports to be distributed across multiple CDM groups with the same pattern. CDM group aggregation can determine the CSI-RS port distribution.

[0066] NR supports multiple flexible aggregation schemes. For the same port configuration, multiple CDM aggregation schemes are supported. NR utilizes CDM group aggregation using three CDM patterns: CDM-2, CDM-4, ​​and CDM-8, flexibly supporting CSI-RSs with 2 to 32 ports. For a multi-port CSI-RS resource, different ports may adopt various multiplexing methods.

[0067] Figure 3 is a schematic diagram of port multiplexing. As shown in Figure 3, a CDM+TDM approach is used. Four CSI-RS ports are aggregated using a CDM-2 pattern and divided into two CDM groups. Each CSI-RS port within a CDM group is mapped to two REs within the pattern. Orthogonal multiplexing is achieved between ports using an orthogonal cover code (OCC) of length 2. Ports within CDM groups (e.g., ports 0, 1 and ports 2, 3) are orthogonalized using TDM.

[0068] Figure 4 is another schematic diagram of port multiplexing. As shown in Figure 4, a CDM+FDM+TDM approach is used. The 24-port CSI-RS resources are aggregated using a CDM-4 pattern and divided into six CDM groups. The CSI-RS ports within each CDM group are orthogonally multiplexed using OCCs of length 4. Different CDM groups are orthogonally multiplexed using TDM or FDM.

[0069] Currently, CSI-RS resource configuration is semi-statically configured via Radio Resource Control (RRC) signaling and generally remains unchanged for a long period of time. If these resources need to be changed, they can be adjusted via RRC reconfiguration.

[0070] The following describes the activation / deactivation of Semi-Persistent CSI (SP-CSI). When a terminal device (UE) is configured with the CSI resource setting with the higher layer parameter resourceType set to semiPersistent:

[0071] - When the UE receives an activation command, for the CSI-RS resource setting for channel measurement and CSI-IM / NZP CSI-RS for interference measurement associated with the CSI resource setting, when the UE transmits the PUCCH corresponding to the HARQ-ACK information of the PDSCH carrying the selection command in slot n, the corresponding behavior will be The first slot after is implemented.

[0072] - When the UE receives a deactivation command, for the CSI-RS resource settings for channel measurement and CSI-IM / NZP CSI-RS for interference measurement associated with the CSI resource settings, when the UE transmits the PUCCH corresponding to the HARQ-ACK information of the PDSCH carrying the selection command in slot n, the corresponding behavior will be The first slot after is implemented.

[0073] If the UE has an activated semi-persistent CSI-RS / CSI-IM resource configuration, or an activated semi-persistent ZP CSI-RS resource set configuration, and there is no corresponding deactivation command, the activated semi-persistent CSI-RS / CSI-IM resource configuration or semi-persistent ZP CSI-RS resource set configuration is considered active during the corresponding DL BWP activation period.

[0074] In some embodiments, the SP CSI-RS / CSI-IM resource set can be used to activate / deactivate the MAC CE. Figure 5 is a schematic diagram of the SP CSI-RS / CSI-IM resource set activation / deactivation MAC CE. The meaning of each field can refer to the relevant technology.

[0075] The following further explains the activation / deactivation of non-periodic CSI-RS. For the CSI-RS resource set associated with the non-periodic, periodic or semi-persistent resource setting, the trigger state of the non-periodic reporting setting and / or the channel / interference measurement resource setting is configured by the high-level parameter CSI-AperiodicTriggerStateList. For the non-periodic CSI reporting trigger, the network device configures a set of CSI trigger state values ​​to the terminal device, and the CSI trigger state can be associated with any candidate BWP. Each code point of the DCI field "CSI request" is associated with a trigger state.

[0076] When the terminal device receives a CSI request, it obtains the CSI report config ID according to the CSI trigger state corresponding to the codepoint in the CSI request field; the terminal device determines the CSI report to be activated; when the aperiodic CSI-RS is used for aperiodic CSI reporting and the aperiodic CSI reporting is activated, it means that the associated aperiodic CSI-RS is also activated, and the CSI-RS offset can be obtained based on the high-level parameter aperiodicTriggeringOffset.

[0077] Table 2 shows some situations of non-periodic trigger cells.

[0078] Table 2CSI-AperiodicTriggerStateList information element

[0079] The spatial / energy domain element adjustment technologies related to network energy saving can be divided into two types.

[0080] Figure 6 illustrates spatial / energy domain element adjustments. As shown on the left side of Figure 6, Type 1 adjustments enable or disable all antennas (factors) associated with a logical antenna port. In this method, the network device can disable all antennas (factors) corresponding to one or more antenna ports. While the transmission power of each port remains unchanged, the total number of antenna ports is reduced. Therefore, this adjustment directly affects the number of antenna ports.

[0081] As shown in the right part of Figure 6, Type 2 adjustment is to enable or disable some antenna factors associated with a logical antenna port. In this way, the network device can shut down some antennas (factors) corresponding to all antenna ports. After shutdown, the number of antenna ports remains unchanged, but the transmission power of each port decreases. Therefore, this adjustment affects the beamforming gain of the network device and thus affects the transmission power of the reference signal.

[0082] In network energy-saving scenarios, such as when antenna configurations change, how to indicate resources is an urgent issue to be resolved. In the following description, the terms "PDCCH" and "physical downlink control channel" or "downlink control information" are interchangeable, and the terms "PDSCH" and "physical downlink data channel" or "downlink data" are also interchangeable, so as to avoid confusion. In addition, transmitting or receiving PDCCH can be understood as transmitting or receiving downlink control information carried by PDCCH; transmitting or receiving PDSCH can be understood as transmitting or receiving downlink data carried by PDSCH.

[0083] Embodiments of the first aspect

[0084] The present invention provides a resource indication method, which is described from the perspective of a terminal device. FIG7 is a schematic diagram of the resource indication method according to the present invention. As shown in FIG7 , the method includes:

[0085] 701. A terminal device receives first information from a network device, where the first information is used to configure at least K resources and / or M ports, where K ≥ 1 and M ≥ 1.

[0086] 702. The terminal device receives second information from the network device, where the second information is at least used to indicate / trigger / activate K1 resources among the K resources and / or M1 ports among the M ports, where 1≤K1≤K, 1≤M1≤M.

[0087] It is worth noting that FIG7 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG7 above.

[0088] In some embodiments, the resource may be a CSI-RS resource, and the port may be a CSI-RS port, but is not limited thereto. For example, the resource may be an NZP CSI-RS resource and / or a CSI-IM resource and / or a ZP CSI-RS resource, but the present application is not limited thereto. The following embodiments are described using CSI-RS as an example, but CSI-IM may also be used instead.

[0089] In some embodiments, the resource is an NZP CSI-RS resource, and the first information is used to configure K NZP CSI-RS resources.

[0090] For example, the first information includes CSI-RS configuration information, the CSI-RS configuration information includes a CSI resource setting for channel measurement, the CSI resource setting includes at least one CSI resource set. The CSI resource set is at least one NZP CSI-RS resource set and / or SSB (SS / PBCH block) set, and the NZP CSI-RS resource set includes K NZP CSI-RS resources.

[0091] In some embodiments, the resource is a ZP CSI-RS resource, and the first information is used to configure K ZP CSI-RS resources.

[0092] For example, the first information includes CSI-RS configuration information, the CSI-RS configuration information includes one or more ZP CSI-RS resource sets (resource set), and the ZP CSI-RS resource set includes K ZP CSI-RS resources (resource), where 1≤K≤16.

[0093] In some embodiments, the port is a CSI-RS port, and the first information is used to configure M ports, where 1≤M.

[0094] For example, the first information includes CSI-RS configuration information, the CSI-RS configuration information includes the NZP CSI-RS resource and / or the ZP CSI-RS resource including a resource mapping information element (Resource Mapping IE), the ResourceMapping IE includes a norOfPort parameter, and the norOfPort parameter is used to configure the number of CSI-RS ports. norOfPort is configured as M, indicating that the terminal device is configured with M ports

[0095] In some embodiments, the resource is a CSI-RS resource, and the first information is used to configure K CSI-RS resources and / or L sub-configurations. The sub-configuration can be replaced with a group or a subset, but the present application is not limited thereto.

[0096] For example, the first information includes CSI-RS configuration information, the CSI-RS configuration information includes a CSI resource setting for channel measurement, the CSI resource setting includes at least one CSI resource set. The CSI resource set is at least one NZP CSI-RS resource set and / or SSB (SS / PBCH block) set, the NZP CSI-RS resource set includes K NZP CSI-RS resources and / or L sub-configurations, one of the L sub-configurations includes R NZP CSI-RS resources, where 1≤L≤K, K=L*R, and R≥1.

[0097] For another example, the first information includes CSI-RS configuration information, the CSI-RS configuration information includes one or more ZP CSI-RS resource sets (resource set), the ZP CSI-RS resource set includes K ZP CSI-RS resources (resource) and / or L sub-configurations, and one sub-configuration among the L sub-configurations contains R ZP CSI-RS resources, where 1≤K≤16, 1≤L≤K, K=L*R, and R≥1.

[0098] In some embodiments, the port is a CSI-RS port, and the first information is used to configure M ports and L sub-configurations, where the sub-configuration can be replaced by a group or a subset.

[0099] For example, the first information includes CSI-RS configuration information, and the CSI-RS configuration information includes K CSI-RS resources. One of the K CSI-RS resources includes a ResourceMapping IE, and the ResourceMapping IE includes a norOfPort parameter, and the norOfPort parameter is used to configure the number of CSI-RS ports. norOfPort is configured to M, indicating that the terminal device is configured with M ports. The first information includes L sub-configurations, and one of the L sub-configurations corresponds to at least one port among the M ports.

[0100] In some embodiments, the second information is used to indicate / trigger / activate K1 resources among the K resources, where 1≤K1≤K.

[0101] For example, the resource is a CSI-RS resource, and the second information is used to indicate / trigger / activate K1 CSI-RS resources among the K CSI-RS resources, where 1≤K1≤K. The second information is CSI-RS indication / trigger / activation information, which may also be referred to as indication / trigger / activation information of a CSI-RS resource / port, or as indication / trigger / activation information of a resource / port. The second information is used to indicate / trigger / activate K1 CSI-RS resources among the K CSI-RS resources in a CSI resource set.

[0102] In some embodiments, the second information is used to instruct / trigger / activate M1 ports among M ports, where 1≤M1≤M.

[0103] For example, the port is a CSI-RS port, and the second information is used to indicate / trigger / activate M1 ports among the M ports, where 1≤M1≤M. The second information is CSI-RS indication / trigger / activation information, which may also be referred to as indication / trigger / activation information of a CSI-RS resource / port, or as resource / port indication / trigger / activation information. The second information is used to indicate / trigger / activate M1 ports among the M ports.

[0104] In some embodiments, the second information is at least used to indicate / trigger / activate at least one sub-configuration / group / subset among the L sub-configurations / groups / subsets.

[0105] For example, the resource is a CSI-RS resource, and the first information is used to configure K resources and / or L sub-configurations, and one sub-configuration / group / subset of the L sub-configurations / groups / subsets corresponds to one or more resources of the K resources. The second information is used to indicate / trigger / activate at least one sub-configuration of the L sub-configurations. For example, the second information is used to indicate / trigger / activate Q sub-configurations of the L sub-configurations, one sub-configuration corresponds to R resources, and indicating / triggering / activating Q sub-configurations of the L sub-configurations is to indicate / trigger / activate K1 resources of the K resources, where K=L*R, K1=Q*R.

[0106] For another example, the port is a CSI-RS port, and the first information is used to configure M ports and / or L sub-configurations, one sub-configuration / group / subset of the L sub-configurations / groups / subsets corresponds to one or more ports of the M ports, and the second information is used to indicate / trigger / activate at least one sub-configuration of the L sub-configurations. For example, the second information is used to indicate / trigger / activate one sub-configuration of the L sub-configurations, and the sub-configuration corresponds to M1 ports. Indicating / triggering / activating one sub-configuration of the L sub-configurations means indicating / triggering / activating M1 ports of the M ports.

[0107] In some embodiments, the terminal device determines (assumes) to transmit CSI-RS on K1 resources and / or M1 ports that are indicated / triggered / activated; and the terminal device performs CSI measurement based on the K1 resources and / or M1 ports that are indicated / triggered / activated.

[0108] For example, the terminal device assumes that the CSI-RS is transmitted on the indicated / triggered / activated CSI-RS resource / port, and the terminal device performs CSI measurement based on the indicated / triggered / activated CSI-RS resource / port.

[0109] In some embodiments, the indication / triggering / activation information of the CSI-RS resource may be a CSI-RS resource ID list, used to indicate one or more CSI-RS resources (Resource) indicated / triggered / activated in the CSI-RS resource set (ResourceSet); the indication / triggering / activation information of the CSI-RS resource may also be resource subset indication information based on a bitmap, where one bit in the bitmap represents a CSI-RS resource or a CSI-RS resource group, and the resources corresponding to the number of bits set to 1 in the bitmap are indicated / triggered / activated, and the resources corresponding to the number of bits set to 0 in the bitmap are not indicated / triggered / activated; the indication / triggering / activation information of the CSI-RS port may be port subset indication information based on a bitmap, where one bit in the bitmap represents a port or a CDM group, and the ports corresponding to the number of bits set to 1 in the bitmap are indicated / triggered / activated, and the ports corresponding to the number of bits set to 0 in the bitmap are not indicated / triggered / activated.

[0110] In some embodiments, the second information is a MAC CE; the MAC CE is at least used to indicate / trigger / activate at least one resource among the K resources in the semi-persistent resource set, and / or, the MAC CE is at least used to indicate / trigger / activate at least one port among the M ports.

[0111] For example, for semi-persistent CSI-RS resources, the indication / triggering / activation information of the CSI-RS resources / ports is carried by a MAC CE, for example. The MAC CE can continue to use the existing semi-persistent CSI-RS activation / deactivation MAC CE, which is used for both activation / deactivation of the CSI-RS resource set and indication / triggering / activation of the CSI-RS resources / ports. That is, the existing MAC CE can be used, or it can be a newly defined MAC CE, which is only used for indication / triggering / activation information of the CSI-RS resources / ports.

[0112] The MAC CE may indicate a CSI-RS resource ID list, i.e., one or more CSI-RS resources (Resource) indicated / triggered / activated in the CSI-RS resource set (ResourceSet), so the MAC CE includes at least a plurality of first fields, the first field width being W bits, where W is a positive integer greater than 1. The first field is used to represent a CSI-RS resource index / ID or a CSI-RS resource group index / ID, or the first field is used to represent a port index / ID or a port group (e.g., CDM group) index / ID, and / or the MAC CE further includes at least a third field, the third field taking a value (e.g., 1 or 0) representing that the first field is used to indicate a CSI-RS port, and the third field taking another value (e.g., 0 or 1) representing that the first field is used to indicate a CSI-RS resource.

[0113] The MAC CE may also indicate a bitmap-based resource / port subset, so the MAC CE includes at least a plurality of second fields, the second field width is one bit, the second field represents a port or a CDM group, or the second field represents a CSI-RS resource or a CSI-RS resource group. The second field is used to indicate / trigger / activate a port or a CDM group, or a CSI-RS resource (group), for example, when it is set to 1, it indicates that the corresponding port or resource is indicated / triggered / activated, and when it is set to 0, it indicates that the corresponding port or resource is not indicated / triggered / activated. And / or, the MAC CE may also include at least a third field, the third field takes a value (for example, 1 or 0) to represent that the second field is used to indicate the CSI-RS port, and when the third field takes another value (for example, 0 or 1), it represents that the second field is used to indicate the CSI-RS resource.

[0114] In some embodiments, the second information is DCI; the DCI is at least used to indicate / trigger / activate at least one resource among the K resources in the non-periodic resource set, and / or, the DCI is at least used to indicate / trigger / activate at least one port among the M ports.

[0115] For example, for aperiodic CSI-RS resources, the indication / triggering / activation information of the CSI-RS resource / port is carried by, for example, DCI (e.g., CSI request field); the DCI (e.g., CSI request field) uses existing signaling, and is used for both aperiodic CSI reporting activation / deactivation, aperiodic CSI-RS resource activation / deactivation, and indication / triggering / activation of aperiodic CSI reporting sub-configuration and indication / triggering / activation of aperiodic CSI-RS resources / ports. The aperiodic CSI-RS may be associated with aperiodic CSI reporting, and the indicated / triggered / activated aperiodic CSI-RS resource / port is the CSI-RS resource / port information included in the indicated / triggered / activated aperiodic CSI reporting sub-configuration.

[0116] In some embodiments, if the terminal device has an activated semi-persistent resource configuration and no deactivation command is received, and the terminal device is indicated / triggered / activated resources / ports; when the corresponding DL BWP is activated, the indicated / triggered / activated semi-persistent resources / ports are determined to be (considered to be) activated, otherwise they are determined to be (considered to be) suspended or deactivated, and / or, in the (valid / activated) resource / port counting, the indicated / triggered / activated semi-persistent resources / ports are determined to be (considered to be) valid / activated, otherwise they are determined to be (considered to be) suspended or invalid / deactivated.

[0117] For example, when the semi-persistent CSI-RS resource is activated and the semi-persistent CSI-RS resource deactivation command is not received, the terminal device does not receive the indication / trigger / activation information of the CSI-RS resource / port, then the K CSI-RS resources (Resource) and / or M CSI-RS ports contained in the CSI-RS resource set (ResourceSet) are all activated; when the semi-persistent / aperiodic CSI-RS resource is activated and the semi-persistent / aperiodic CSI-RS resource deactivation command is not received, the terminal device receives the indication / trigger / activation information of the CSI-RS resource / port, the CSI-RS resource / port The indication / trigger / activation information is used to indicate / trigger / activate K1 resources out of K resources, and / or M1 ports out of M ports, then the terminal device assumes that the K1 CSI-RS resources and / or M1 ports indicated / triggered / activated are activated, and the CSI-RS resources / ports that are not indicated / triggered / activated in the CSI-RS resource set (ResourceSet) are suspended / deactivated until the terminal device receives a CSI-RS deactivation command or receives another CSI-RS resource / port indication / trigger / activation information, and the indication / trigger / activation status / information of the current CSI-RS resource / port is canceled or overwritten. In the (valid / activated) resource / port counting, the K1 semi-persistent resources and / or M1 ports that are indicated / triggered / activated are determined to be (considered to be) valid / activated, otherwise they are determined to be (considered to be) suspended or invalid / deactivated.

[0118] In some embodiments, when the CSI-RS resource is indicated / activated / triggered and no deactivation command is received, the second information received at a later time point overwrites the second information received at a previous time point. The terminal device determines that K1 resources of the K resources and / or M1 ports of the M ports indicated / triggered / activated by the second information received at the previous time point are canceled or overwritten.

[0119] In some embodiments, the terminal device receives a deactivation command from the network device; and the terminal device determines that K1 of the K resources and / or M1 of the M ports indicated / triggered / activated by the second information are canceled or covered.

[0120] For example, in the existing protocol, when the semi-persistent / aperiodic CSI-RS resource is activated and no semi-persistent / aperiodic CSI-RS resource deactivation command is received, all CSI-RS resources (Resource) and all CSI-RS ports contained in the CSI-RS resource set (ResourceSet) are activated.

[0121] In an embodiment of the present application, when the semi-persistent / aperiodic CSI-RS resource is activated and the semi-persistent / aperiodic CSI-RS resource deactivation command is not received, the terminal device does not receive the indication / trigger / activation information of the CSI-RS resource / port, then all CSI-RS resources (Resource) and all CSI-RS ports contained in the CSI-RS resource set (ResourceSet) are activated; when the semi-persistent / aperiodic CSI-RS resource is activated and the semi-persistent / aperiodic CSI-RS resource deactivation command is not received, the terminal device receives the indication / trigger / activation information of the CSI-RS resource / port, then the terminal device assumes that the indicated / triggered / activated CSI-RS resource / port is activated, and the CSI-RS resource / port that is not indicated / triggered / activated in the CSI-RS resource set (ResourceSet) is deactivated, until the terminal device receives the CSI-RS deactivation command or receives another CSI-RS resource / port indication / trigger / activation information, the indication / trigger / activation status / information of the current CSI-RS resource / port is canceled or overwritten.

[0122] The following first takes the indication / triggering / activation of semi-persistent CSI-RS resources / ports based on MAC CE as an example for explanation.

[0123] In some embodiments, the terminal device receives a MAC CE from the network device, where the MAC CE is used to activate the semi-persistent CSI-RS resource, and the MAC CE is used to indicate / trigger / activate K1 CSI-RS resources (Resource) of the K CSI-RS resources (Resource) in the CSI-RS resource set (ResourceSet); or, the MAC CE is used to indicate / trigger / activate M1 CSI-RS ports among the M CSI-RS ports in the CSI-RS resource set (ResourceSet).

[0124] That is, the MAC CE used for indication / triggering / activation of CSI-RS resources / ports can use the existing semi-persistent CSI-RS activation / deactivation MAC CE, which is used for both activation / deactivation of CSI-RS resources and indication / triggering / activation of CSI-RS resources / ports.

[0125] In some embodiments, the terminal device receives a MAC CE from the network device, where the MAC CE is used to activate the semi-persistent CSI-RS resources; the terminal device then receives another MAC CE from the network device, where the MAC CE is used to indicate / trigger / activate K1 CSI-RS resources (Resource) of the K CSI-RS resources (Resource) in the CSI-RS resource set (ResourceSet), or the MAC CE is used to indicate / trigger / activate M1 CSI-RS ports among the M CSI-RS ports in the CSI-RS resource set (ResourceSet).

[0126] That is, the MAC CE used for indication / triggering / activation of CSI-RS resources / ports can be a newly defined MAC CE that is different from the semi-persistent CSI-RS activation / deactivation. The terminal device assumes that it receives two MAC CEs at the same time, one MAC CE is used for semi-persistent CSI-RS activation / deactivation, and the other MAC CE is used to indicate / trigger / activate at least one CSI-RS resource / port; or the terminal assumes that it first receives a MAC CE for semi-persistent CSI-RS activation, and then receives a MAC CE for semi-persistent CSI-RS resource / port indication / triggering / activation after confirming the semi-persistent CSI-RS activation; that is, the terminal device assumes that the indication / triggering / activation of semi-persistent CSI-RS resources / ports is performed at the same time as the corresponding CSI-RS resource activation or after the CSI-RS resource activation.

[0127] The MAC CE may indicate a CSI-RS resource ID list, i.e., one or more CSI-RS resources (Resource) indicated / triggered / activated in the CSI-RS resource set (ResourceSet), so the MAC CE includes at least a plurality of first fields, the first field width being W bits, where W is a positive integer greater than 1. The one first field is used to represent a CSI-RS resource index / ID or a CSI-RS resource group index / ID, or the one first field is used to represent a port index / ID or a port group (e.g., CDM group) index / ID, and the MAC CE further includes at least a third field, the third field taking a value (e.g., 1 or 0) representing that the first field is used to indicate a CSI-RS port, and the third field taking another value (e.g., 0 or 1) representing that the first field is used to indicate a CSI-RS resource.

[0128] The MAC CE may also indicate a bitmap-based resource / port subset, so the MAC CE includes at least a plurality of second fields, the second field width is one bit, the second field represents a port or a CDM group, or the second field represents a CSI-RS resource or a CSI-RS resource group. The second field is used to indicate / trigger / activate a port or a CDM group, or a CSI-RS resource (group), for example, when it is set to 1, it indicates that the corresponding port or resource is indicated / triggered / activated, and when it is set to 0, it indicates that the corresponding port or resource is not indicated / triggered / activated. The MAC CE may also include at least a third field, the third field taking a value (for example, 1 or 0) represents that the second field is used to indicate the CSI-RS port, and when the third field takes another value (for example, 0 or 1), it represents that the second field is used to indicate the CSI-RS resource.

[0129] In some embodiments, the terminal device assumes that CSI-RS is transmitted on CSI-RS resources / ports that are indicated / triggered / activated, and is not transmitted on CSI-RS resources / ports that are not / not indicated / triggered / activated; therefore, the terminal device performs CSI measurement on CSI-RS resources / ports that are indicated / triggered / activated.

[0130] If the terminal device receives a MAC CE from the network device for indicating / triggering / activating CSI-RS resources / ports at a later time, the terminal device assumes that the indication / triggering / activation information of the CSI-RS resources / ports covers the indication / triggering / activation information of the CSI-RS resources / ports received previously.

[0131] The terminal device receives a MAC CE from the network device, where the MAC CE is used to deactivate the current semi-persistent CSI-RS. Then, the indication / triggering / activation information of the CSI-RS resource / port is also deactivated or considered invalid.

[0132] Therefore, CSI-RS is transmitted on resources / ports that are indicated / triggered / activated, and is not transmitted on resources / ports that are not / not indicated / triggered / activated, which can help save network energy. At the same time, other channels can be transmitted on resources / ports that are not / not indicated / triggered / activated, such as PDSCH, which can improve spectrum utilization.

[0133] In addition, the CSI-RS resource configuration can use the existing RRC configuration information, and the protocol changes are relatively minor. Under the premise that the CSI-RS resource configuration remains unchanged, the existing MAC CE or the newly defined MAC CE is used to indicate / trigger / activate the CSI-RS resource / port, which is a simple and effective method.

[0134] The following embodiments are further explained by taking network energy saving as an example.

[0135] For example, the NZP CSI-RS resource configuration for channel measurement in network energy-saving spatial domain adjustment may include:

[0136] - First resource configuration type (e.g., A1-1-revised type): A resource set in a resource setting includes one or more resources, where a resource is associated with a spatial adaptation pattern;

[0137] - Second resource configuration type (e.g., A1-2-revised type): A resource set in a resource setting includes at least one resource, where a resource can be associated with one or more spatial adaptation patterns.

[0138] For another example, the NZP CSI-RS resource configuration for channel measurement in network energy-saving energy domain adjustment includes:

[0139] -Second resource configuration type (e.g., A1-2-revised type): A resource set in a resource setting includes at least one resource, wherein a resource can be associated with one or more power offset values, that is, a resource can be associated with one or more energy domain adjustment patterns.

[0140] In some embodiments, the binding relationship between the spatial / energy domain adjustment type and the resource configuration can be at least one of the following: the spatial domain adjustment of type 1 supports the second resource configuration type (for example, the A1-2-revised type); the spatial domain adjustment of type 2 supports the first resource configuration type (for example, the A1-1-revised type); the energy domain adjustment can support the second resource configuration type (for example, the A1-2-revised type).

[0141] In some embodiments, the CSI reporting configuration includes multiple sub-configurations.

[0142] For example, a CSI reporting configuration may include L sub-configurations, where each sub-configuration corresponds to a spatial / energy domain adjustment mode and each sub-configuration corresponds to a CSI result. If L in the CSI reporting configuration is greater than 1, each sub-configuration includes the following information:

[0143] For example, for type 1 spatial domain adjustment using the second resource configuration type (e.g., A1-2-revised type), each subconfiguration contains one or more of the following information: N1, N2 information for a single antenna panel, and N1, N2, Ng information for a multi-antenna panel; bitmap-based port subset indication information, where one bit corresponds to one port; codebook subset restriction information; and rank restriction information.

[0144] For example, for type 2 spatial domain adjustment using the first resource configuration type (e.g., A1-1-revised type), each sub-configuration contains the following information: a CSI-RS resource ID list, which may contain one CSI-RS resource ID or multiple CSI-RS resource IDs, so that one sub-configuration can be associated with at least one CSI-RS resource ID.

[0145] For another example, for energy domain adjustment, each sub-configuration is associated with a power offset (powerControlOffset).

[0146] In some embodiments, the association between CSI-RS resource configuration and sub-configuration is as follows:

[0147] For example, for the first resource configuration type (for example, the A1-1-revised type), one or more CSI-RS resources in a CSI-RS resource set for channel measurement can be associated with the same sub-configuration provided in the CSI reporting configuration, that is, a sub-configuration in the CSI reporting configuration can be associated with one or more CSI-RS resources in a CSI-RS resource set for channel measurement; wherein the resources in the resource set for channel measurement have the same number of antenna ports.

[0148] For another example, for the second resource configuration type (e.g., A1-2-revised type), all CSI-RS resources (which may be one or more) in the CSI-RS resource set for channel measurement are associated with each sub-configuration provided in the CSI report configuration, that is, each CSI-RS resource is associated with all sub-configurations, and the resources in the resource set for channel measurement have the same number of antenna ports.

[0149] In some embodiments, the CSI reporting process for multiple sub-configurations is as follows: For a CSI reporting configuration containing L sub-configurations, a framework needs to be supported so that a terminal device can report N CSIs at a reporting time, where N CSIs are associated with N sub-configurations in L (where 1≤N≤L), and each CSI corresponds to one sub-configuration. Where N=1 represents a single CSI report, and N>1 represents multiple CSI reports.

[0150] For semi-continuous / aperiodic CSI reporting, the base station supports triggering / indicating / activating N CSI reports in L, where 1≤N≤L; the maximum values ​​of L and N depend on the terminal capabilities. The specific triggering mechanism is as follows:

[0151] - For PUSCH-based aperiodic CSI and semi-persistent CSI reporting, support for DCI-based triggering:

[0152] For example, a trigger state associated with N sub-configurations is indicated by the CSI request field in the existing DCI. Different trigger states can represent different subsets of the L sub-configurations. Wherein, the DCI is UE-specific (in this case, the traditional DCI format applies);

[0153] For example, for A-CSI-RS, the CPU and CSI-RS resource / port calculations depend on the indicated N sub-configurations.

[0154] - For PUCCH-based semi-persistent CSI reporting, support for MAC CE-based triggering:

[0155] For example, it supports selecting indication information of N sub-configurations in one MAC-CE.

[0156] The above describes CSI reporting, and the following describes resource configuration / indication.

[0157] The following further illustrates the CSI-RS resource sub-configuration by way of example.

[0158] In some embodiments, a CSI-RS resource configuration may include L sub-configurations, where one sub-configuration among the L sub-configurations corresponds to a CSI-RS port subset indication information, and / or a powerControlOffset, and / or a CSI-RS resource ID list.

[0159] For example, for type 2 spatial domain adjustment based on the first resource configuration type (e.g., A1-1-revised type) for network energy saving, a CSI-RS resource set for channel measurement includes L sub-configurations, one of the L sub-configurations includes a CSI-RS resource ID list, that is, a sub-configuration is associated with one or more CSI-RS resources in the CSI-RS resource set.

[0160] For example, a CSI-RS resource set in the CSI-RS resource setting includes 8 CSI-RS resources, namely, CSI-RS resources 0 to 7. The CSI-RS resource set includes 4 sub-configurations, each sub-configuration corresponds to 2 CSI-RS resources, namely, sub-configuration 0 corresponds to CSI-RS resources 0 and 1, sub-configuration 1 corresponds to CSI-RS resources 2 and 3, sub-configuration 2 corresponds to CSI-RS resources 4 and 5, and sub-configuration 4 corresponds to CSI-RS resources 6 and 7.

[0161] For another example, for type 1 spatial domain adjustment of the second resource configuration type for network energy saving (e.g., A1-2-revised type), a CSI-RS resource set for channel measurement includes L subconfigurations, and one of the L subconfigurations includes a bitmap-based port subset indication information, where the port indication information is used to indicate a port subset / partial port of a CSI-RS resource, with one bit corresponding to one port. Accordingly, one of the L subconfigurations is associated with all CSI-RS resources in the CSI-RS resource set, or in other words, each CSI-RS resource is associated with all subconfigurations.

[0162] For example, a CSI-RS resource set in the CSI-RS resource setting includes 8 CSI-RS resources, CSI-RS resources 0 to 7, each of which includes 32 ports, i.e., port indexes 0 to 31. The CSI-RS resource set includes 4 sub-configurations, sub-configuration 0 corresponds to CSI-RS resource ports 0 to 31, sub-configuration 1 corresponds to CSI-RS resource ports 0 to 15, sub-configuration 2 corresponds to CSI-RS resource ports 0 to 7, and sub-configuration 4 corresponds to CSI-RS resource ports 0 to 3. The ports corresponding to each sub-configuration can have consecutive or discontinuous port numbers. The port subset indication information is a bitmap-based indication, where a port corresponding to a bit set to 1 indicates that it is indicated / triggered / activated, and a port corresponding to a bit set to 0 indicates that it is not indicated / triggered / activated.

[0163] In some embodiments, for the first resource configuration type (e.g., A1-1-revised type) of network energy saving, the implementation steps may include:

[0164] -The terminal device receives the semi-persistent CSI-RS resource configuration information including L sub-configurations configured by the network device:

[0165] For example, the terminal device receives a semi-persistent CSI-RS resource setting configured by the network device, wherein the CSI-RS resource setting includes at least one CSI-RS resource set (ResourceSet), and the CSI-RS resource set (resource set) includes K CSI-RS resources (resource), wherein one CSI-RS resource is associated with only one spatial adaptation pattern (spatial adaptation pattern); for example, a CSI-RS resource set (resource set) in the CSI-RS resource setting (resource setting) includes 8 CSI-RS resources (resource), CSI-RS resources (resource) 0 to 7.

[0166] The CSI-RS resource set includes L sub-configurations, one of the L sub-configurations includes a CSI-RS resource ID list, and the list includes one or more CSI-RS resource IDs. That is, one sub-configuration corresponds to one or more CSI-RS resources.

[0167] For example, a CSI-RS resource set in the CSI-RS resource setting includes 4 sub-configurations, each sub-configuration corresponds to 2 CSI-RS resources, that is, sub-configuration 0 corresponds to CSI-RS resources 0 and 1, sub-configuration 1 corresponds to CSI-RS resources 2 and 3, sub-configuration 2 corresponds to CSI-RS resources 4 and 5, and sub-configuration 4 corresponds to CSI-RS resources 6 and 7.

[0168] The high-level parameter powerControlOffsetSS in multiple CSI-RS resources corresponding to the same sub-configuration has the same value, and the high-level parameter powerControlOffsetSS in different CSI-RS resources corresponding to different sub-configurations has different values;

[0169] For example, a CSI-RS resource set in the CSI-RS resource setting includes 4 sub-configurations, sub-configuration 0 corresponds to powerControlOffsetSS=0 (dB) in CSI-RS resources 0 and 1, sub-configuration 1 corresponds to powerControlOffsetSS=-3 (dB) in CSI-RS resources 2 and 3, sub-configuration 2 corresponds to powerControlOffsetSS=3 (dB) in CSI-RS resources 4 and 5, and sub-configuration 4 corresponds to powerControlOffsetSS=6 (dB) in CSI-RS resources 6 and 7.

[0170] -The terminal device receives a MAC CE from the network device, where the MAC CE is used to activate the semi-persistent CSI-RS resource, and the MAC CE is used to indicate / trigger / activate at least one sub-configuration of L sub-configurations in the CSI-RS resource set (ResourceSet).

[0171] That is, the MAC CE for indicating / triggering / activating CSI-RS resources / ports follows the existing MAC CE for semi-persistent CSI-RS activation / deactivation, and the MAC CE is used for both activating / deactivating CSI-RS resources and indicating / triggering / activating sub-configurations.

[0172] Alternatively, the terminal device receives a MAC CE from the network device, where the MAC CE is used to activate the semi-persistent CSI-RS resources; the terminal device then receives another MAC CE from the network device, where the MAC CE is used to indicate / trigger / activate at least one of the L sub-configurations.

[0173] That is, the MAC CE used for CSI-RS resource subconfiguration indication / triggering / activation is a newly defined MAC CE that is different from the semi-persistent CSI-RS activation / deactivation. The terminal device assumes that it receives two MAC CEs at the same time, one MAC CE is used for semi-persistent CSI-RS activation / deactivation, and the other MAC CE is used to indicate / trigger / activate at least one CSI-RS resource / port; or the terminal assumes that it first receives a MAC CE for semi-persistent CSI-RS activation, and then receives a MAC CE for semi-persistent CSI-RS resource subconfiguration indication / triggering / activation after confirming the semi-persistent CSI-RS activation; that is, the terminal device assumes that the indication / triggering / activation of the semi-persistent CSI-RS resource subconfiguration is performed at the same time as the corresponding CSI-RS resource activation or after the CSI-RS resource activation.

[0174] For example, a CSI-RS resource set in the CSI-RS resource setting includes 4 sub-configurations, and the MAC CE is used to activate sub-configuration 0 and sub-configuration 1 of the 4 sub-configurations, that is, to activate 4 CSI-RS resources out of 8 CSI-RS resources in the CSI-RS resource set, that is, to activate CSI-RS resources 0 to 3 out of CSI-RS resources 0 to 7.

[0175] The MAC CE is used to indicate one or more sub-configurations, and thus the MAC CE includes at least multiple first fields, each of which has a bit width of W bits, where W is a positive integer greater than 1. The one first field is used to represent a CSI-RS sub-configuration index / ID; or the MAC CE includes at least multiple second fields, each of which has a bit width of one bit, and the one second field is used to indicate / trigger / activate a sub-configuration, where a second field set to 1 indicates that the corresponding port or resource is indicated / triggered / activated, and a second field set to 0 indicates that the corresponding port resource is not indicated / triggered / activated.

[0176] -The terminal device assumes that the CSI-RS is transmitted on the time-frequency resources corresponding to the indicated / triggered / activated CSI-RS resource subconfiguration, and does not transmit on the time-frequency resources corresponding to the unindicated / triggered / activated CSI-RS resource subconfiguration; therefore, the terminal device performs CSI measurement on the time-frequency resources corresponding to the indicated / triggered / activated CSI-RS resource subconfiguration.

[0177] For example, the terminal device assumes that the CSI-RS is transmitted on CSI-RS resources 0 to 3 corresponding to sub-configurations 0 and 1, and the terminal device performs CSI measurement based on CSI-RS resources 0 to 3 corresponding to sub-configurations 0 and 1.

[0178] -If the terminal device receives a MAC CE from the network device at a later time for indicating at least one sub-configuration of the L sub-configurations, the terminal device assumes that the sub-configuration indication information covers the sub-configuration indication information received previously.

[0179] For example, the terminal receives a MAC CE indicated by the sub-configuration in the above step at time T1, and the MAC CE indicates sub-configurations 0 and 1. The terminal device assumes that the CSI-RS is transmitted on the CSI-RS resources (resource) corresponding to sub-configurations 0 and 1, and the terminal device performs CSI measurement based on the CSI-RS resources (resource) 0 to 3 corresponding to sub-configurations 0 and 1; if the terminal device receives a MAC CE indicated by the sub-configuration again at time T2, and the MAC CE indicates sub-configurations 2 and 3, the terminal device assumes that the CSI-RS is transmitted on the CSI-RS resources (resource) corresponding to sub-configurations 2 and 3, and the terminal device overwrites the sub-configuration information received at time T1 with the sub-configuration information received at time T2. After time T2, the terminal performs CSI measurement based on the CSI-RS resources (resource) 4 to 7 corresponding to sub-configurations 2 and 3.

[0180] -The terminal device receives a MAC CE from the network device, where the MAC CE is used to deactivate the current semi-persistent CSI-RS, and the CSI-RS resource sub-configuration indication information is also deactivated or considered invalid.

[0181] Therefore, CSI-RS is transmitted on resources / ports that are indicated / triggered / activated, and is not transmitted on resources / ports that are not / not indicated / triggered / activated, which can help save network energy. At the same time, other channels can be transmitted on resources / ports that are not / not indicated / triggered / activated, such as PDSCH, which can improve spectrum utilization.

[0182] In addition, the concept of CSI-RS resource sub-configuration is introduced, and indication / triggering / activation based on the sub-configuration can save energy on MAC CE signaling overhead.

[0183] For example, a CSI-RS resource set includes 16 CSI-RS resources, and the CSI-RS resource set includes 4 sub-configurations, each sub-configuration corresponds to 4 CSI-RS resources, and the MAC CE can use 4 bits to indicate the triggering / activation status of the sub-configuration, that is, to indicate the triggering / activation status of the CSI-RS resource; if the sub-configuration is not introduced, the MAC CE needs to use 16 bits to indicate the triggering / activation status of the CSI-RS resource.

[0184] For example, the CSI-RS resource set contains 4 sub-configurations, corresponding to 32, 16, 8 and 4 ports of CSI-RS resources respectively. The MAC CE can use 4 bits to indicate the triggering / activation status of the sub-configuration, that is, the triggering / activation status of the CSI-RS port; if the sub-configuration is not introduced, the MAC CE needs to use 32 bits to indicate the triggering / activation status of the CSI-RS port.

[0185] The sub-configuration introduced above can be replaced by a group or a subset, etc., and the present application is not limited thereto.

[0186] In some embodiments, for the second resource configuration type (e.g., A1-2-revised type) for network energy saving, the implementation steps may include:

[0187] -The terminal device receives the semi-persistent CSI-RS resource configuration information including L sub-configurations configured by the network device:

[0188] For example, a terminal device receives a semi-persistent CSI-RS resource setting configured by a network device, wherein a CSI-RS resource set in the resource setting includes multiple CSI-RS resources, wherein one CSI-RS resource is associated with all spatial adaptation patterns; for example, a CSI-RS resource set in the CSI-RS resource setting includes 8 CSI-RS resources, CSI-RS resources 0 to 7.

[0189] Each CSI-RS resource is configured with the same number of ports, that is, the nrofPort in the resourceMapping IE in each CSI-RS resource is configured with the same value. For example, if the nrofPort in the resourceMapping IE in each CSI-RS resource is configured as 32, the total number of ports in each CSI-RS resource is 32.

[0190] A resource set in the resource setting includes L subconfigurations, and one of the L subconfigurations includes port subset indication information based on a bitmap, where the port indication information is used to indicate a port subset / partial port of a CSI-RS resource, with one bit corresponding to one port.

[0191] For example, a CSI-RS resource set in the CSI-RS resource setting includes four sub-configurations, each of which corresponds to a 32-bit bitmap for representing port subset information, as described in Table 3 below:

[0192] Table 3

[0193] - The terminal device receives a MAC CE from the network device, where the MAC CE is used to activate the semi-persistent CSI-RS resource and the MAC CE is used to indicate / trigger / activate at least one sub-configuration of the L sub-configurations in the CSI-RS resource set (ResourceSet);

[0194] That is, the MAC CE for indicating / triggering / activating CSI-RS resources / ports follows the existing MAC CE for semi-persistent CSI-RS activation / deactivation, and the MAC CE is used for both activation / deactivation of CSI-RS resources and indication / triggering / activation of sub-configurations.

[0195] Alternatively, the terminal device receives a MAC CE from the network device, where the MAC CE is used to activate the semi-persistent CSI-RS resources; the terminal device then receives another MAC CE from the network device, where the MAC CE is used to indicate / trigger / activate at least one of the L sub-configurations.

[0196] That is, the MAC CE used for CSI-RS resource subconfiguration indication / triggering / activation is a newly defined MAC CE that is different from the semi-persistent CSI-RS activation / deactivation. The terminal device assumes that it receives two MAC CEs at the same time, one MAC CE is used for semi-persistent CSI-RS activation / deactivation, and the other MAC CE is used to indicate / trigger / activate at least one CSI-RS resource / port; or the terminal assumes that it first receives a MAC CE for semi-persistent CSI-RS activation, and then receives a MAC CE for semi-persistent CSI-RS resource subconfiguration indication / triggering / activation after confirming the semi-persistent CSI-RS activation; that is, the terminal device assumes that the indication / triggering / activation of the semi-persistent CSI-RS resource subconfiguration is performed at the same time as the corresponding CSI-RS resource activation or after the CSI-RS resource activation.

[0197] For example, a CSI-RS resource set in the CSI-RS resource setting includes 4 sub-configurations, and the MAC CE is used to activate sub-configuration 1 of the 4 sub-configurations, that is, ports 0 to 15 of the 32 ports of the CSI-RS resource are activated, and ports 16 to 31 are deactivated.

[0198] The MAC CE is used to indicate one or more sub-configurations, and thus the MAC CE includes at least multiple first fields, each of which has a bit width of W bits, where W is a positive integer greater than 1. The one first field is used to represent a CSI-RS sub-configuration index / ID; or the MAC CE includes at least multiple second fields, each of which has a bit width of one bit, and the one second field is used to indicate / trigger / activate a sub-configuration, for example, if set to 1, it indicates that the corresponding port or resource is indicated / triggered / activated, and if set to 0, it indicates that the corresponding port resource is not indicated / triggered / activated.

[0199] -The terminal device assumes that the CSI-RS is transmitted on the time-frequency resources corresponding to the indicated / triggered / activated CSI-RS resource subconfiguration, and does not transmit on the time-frequency resources corresponding to the unindicated / triggered / activated CSI-RS resource subconfiguration; therefore, the terminal device performs CSI measurement on the time-frequency resources corresponding to the indicated / triggered / activated CSI-RS resource subconfiguration.

[0200] For example, the terminal device assumes that the CSI-RS is transmitted on ports 0 to 15 corresponding to sub-configuration 1. The terminal device performs CSI measurement based on the time-frequency resources corresponding to ports 0 to 15, and does not perform CSI measurement on the time-frequency resources corresponding to ports 16 to 31.

[0201] -If the terminal device receives another MAC CE from the network device indicating N sub-configurations among the L sub-configurations, the terminal device assumes that the sub-configuration indication information covers the previously received sub-configuration indication information.

[0202] For example, the terminal receives the MAC CE indicated by the sub-configuration in the above step at time T1, and the MAC CE indicates sub-configuration 1. The terminal device determines that the CSI-RS is transmitted on ports 0 to 15 corresponding to sub-configuration 1, and performs CSI measurement according to the CSI-RS ports 0 to 15 corresponding to sub-configuration 1; if the terminal device receives the MAC CE indicated by the sub-configuration again at time T2, and the MAC CE indicates sub-configuration 3, the terminal device overwrites the sub-configuration information received at time T1 with the sub-configuration information received at time T2. After time T2, the terminal device determines that the CSI-RS is transmitted on ports 0 to 3 corresponding to sub-configuration 3, and performs CSI measurement according to ports 0 to 3 corresponding to sub-configuration 3.

[0203] -The terminal device receives a MAC CE from the network device, where the MAC CE is for deactivating the current semi-persistent CSI-RS, and the sub-configuration indication information of the CSI-RS resource configuration is also deactivated or considered invalid.

[0204] Therefore, CSI-RS is transmitted on resources / ports that are indicated / triggered / activated, and is not transmitted on resources / ports that are not / not indicated / triggered / activated, which can help save network energy. At the same time, other channels can be transmitted on resources / ports that are not / not indicated / triggered / activated, such as PDSCH, which can improve spectrum utilization.

[0205] In addition, the introduction of the CSI-RS resource sub-configuration concept and indication / triggering / activation based on the sub-configuration can save MAC CE signaling overhead.

[0206] For example, a CSI-RS resource set includes 16 CSI-RS resources, and the CSI-RS resource set includes 4 sub-configurations, each sub-configuration corresponds to 4 CSI-RS resources, and the MAC CE can use 4 bits to indicate the triggering / activation status of the sub-configuration, that is, to indicate the triggering / activation status of the CSI-RS resource; if the sub-configuration is not introduced, the MAC CE needs to use 16 bits to indicate the triggering / activation status of the CSI-RS resource.

[0207] For example, the CSI-RS resource set contains 4 sub-configurations, corresponding to 32, 16, 8 and 4 ports of CSI-RS resources respectively. The MAC CE can use 4 bits to indicate the triggering / activation status of the sub-configuration, that is, the triggering / activation status of the CSI-RS port; if the sub-configuration is not introduced, the MAC CE needs to use 32 bits to indicate the triggering / activation status of the CSI-RS port.

[0208] For the MAC CE of the embodiment of the present application, the existing semi-persistent CSI-RS activation / deactivation MAC CE can be used. For example, the existing SP CSI-RS / CSI-IM resource set activation / deactivation MAC CE can be used, and the reserved field R is used for indicating / triggering / activating the semi-persistent CSI-RS resource / port.

[0209] Therefore, using the existing MAC CE can save MAC CE overhead and reduce the workload of standardization; semi-persistent CSI-RS activation and semi-persistent CSI-RS resource / port indication / triggering / activation can be performed simultaneously.

[0210] In addition, a new MAC CE for semi-persistent CSI-RS resource / port indication / triggering / activation can also be defined. This newly defined MAC CE makes the indication / triggering / activation of semi-persistent CSI-RS resources / ports more flexible, allowing multiple CSI-RS resource / port indication / triggering / activation after CSI-RS resource activation.

[0211] The following takes the indication / triggering / activation of aperiodic CSI-RS resources / ports based on DCI as an example for explanation.

[0212] In some embodiments, a terminal device is configured with an aperiodic CSI reporting configuration comprising L sub-configurations, and the terminal device receives DCI signaling, the DCI signaling being used to activate the CSI reporting and simultaneously indicating at least one sub-configuration of the L sub-configurations. If the aperiodic CSI reporting configuration is associated with an aperiodic CSI-RS resource configuration, the DCI signaling is also used to activate the aperiodic CSI-RS resource configuration.

[0213] In an embodiment of the present application, the DCI signaling can be used to indicate / trigger / activate the aperiodic CSI-RS resource / port while activating the aperiodic CSI, activating the associated aperiodic CSI-RS, and indicating the CSI reporting configuration sub-configuration.

[0214] The configuration / indication of aperiodic CSI-RS resources / ports based on DCI may include:

[0215] The terminal device receives an aperiodic CSI reporting configuration configured by the network device, which includes L sub-configurations. Each sub-configuration corresponds to a spatial / energy domain adjustment mode and a CSI result. If L in the CSI reporting configuration is greater than 1, each sub-configuration includes the following information:

[0216] For type 1 spatial domain adjustment using the second resource configuration type (e.g., A1-2-revised type), each subconfiguration includes the following information: N1 and N2 information for a single antenna panel, and N1, N2, and Ng information for a multi-antenna panel; bitmap-based port subset indication information, where one bit corresponds to one port; codebook subset restriction information; and rank restriction information.

[0217] For type 2 spatial domain adjustment using the first resource configuration type (e.g., A1-1-revised type), each sub-configuration includes the following information: a CSI-RS resource ID list, where the list may include one CSI-RS resource ID or multiple CSI-RS resource IDs. Therefore, one sub-configuration may be associated with at least one CSI-RS resource ID;

[0218] For energy domain adjustment, each sub-configuration is associated with: a power offset (powerControlOffset).

[0219] -The terminal device receives a trigger state list CSI-AperiodicTriggerStateList of a group of associated L sub-configurations configured by the network device. The list contains multiple trigger states CSI-AperiodicTriggerState, and one trigger state contains multiple CSI-associated package configuration information CSI-AssociatedReportConfigInfo. The trigger state list or trigger state or associated reporting configuration may include sub-configurations that need to be indicated / triggered / activated.

[0220] -The terminal device receives DCI signaling (CSI request) from the network device, where the CSI request field is used to activate the aperiodic CSI reporting and the associated aperiodic CSI-RS resources, and is also used to indicate / trigger / activate at least one sub-configuration among the L sub-configurations.

[0221] -The terminal device receives the CSI request, which is used to activate the non-periodic CSI reporting, activate the non-periodic CSI-RS resource associated therewith, and indicate / trigger / activate at least one sub-configuration of L sub-configurations, and is also used to indicate / trigger / activate the non-periodic CSI-RS resource / port. The indicated / triggered / activated CSI-RS resource / port corresponds to / is associated with the sub-configuration of the indicated / triggered / activated CSI reporting configuration, that is, the indicated / triggered / activated CSI-RS resource / port corresponds to the CSI-RS resource / port information contained in the sub-configuration of the indicated / triggered / activated CSI reporting configuration.

[0222] For example, if the sub-configuration in the non-periodic CSI reporting configuration corresponds to the first resource configuration type (for example, the A1-1-revised type), the sub-configuration includes a CSI-RS resource ID list, that is, one sub-configuration corresponds to / associated with one or more CSI-RS resources; when the DCI signaling (CSI request) indicates one of the L sub-configurations, the CSI-RS resources in the CSI-RS resource list contained in the indicated sub-configuration are indicated / triggered / activated, and the other CSI-RS resources (Resource) in the CSI-RS resource set (ResourceSet) are in a deactivated / inactivated state.

[0223] For another example, if the sub-configuration in the non-periodic CSI reporting configuration includes a port subset indication information for indicating some ports / port subsets; when the DCI signaling (CSI request) indicates one of the L sub-configurations, the CSI-RS port corresponding to the port subset indication information (bitmap) contained in the indicated sub-configuration is indicated / triggered / activated, that is, the port set to 1 in the bitmap of the port subset indication information is indicated / triggered / activated, and the remaining ports are in a deactivated / inactivated state.

[0224] Therefore, CSI-RS is transmitted on resources / ports that are indicated / triggered / activated, and is not transmitted on resources / ports that are not / not indicated / triggered / activated, which can help save network energy. At the same time, other channels can be transmitted on resources / ports that are not / not indicated / triggered / activated, such as PDSCH, which can improve spectrum utilization.

[0225] In addition, one DCI signaling is used for both indication of the sub-configuration of the CSI reporting configuration and indication / triggering / activation of the CSI-RS resource / port. This method is simple and effective, and can save DCI signaling overhead.

[0226] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used individually, or one or more of the above embodiments may be combined.

[0227] It can be seen from the above embodiments that even when resources change in some scenarios of wireless communication applications (such as energy-saving mode), the network device sends resource / port indication / trigger / activation information to the terminal device, which can indicate the resources in a timely and accurate manner. As a result, the terminal device can correctly receive signals (such as CSI-RS) based on the indication information, thereby improving frequency resource utilization and enhancing energy-saving gains.
