Description

Information indication, information receiving device and method Technical Field

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

[0002] Network energy conservation is crucial for environmental sustainability, reducing environmental impact (greenhouse gas emissions), and saving operating costs. With the proliferation of fifth-generation mobile communication technology (5G) across various industries and geographic regions, and the need for very high data rates to handle more advanced services and applications, network deployments are becoming denser, utilizing more antennas, greater bandwidth, and more frequency bands. The environmental impact of 5G needs to be managed, and new solutions are needed to improve network energy conservation.

[0003] Energy consumption has become a significant component of operators' operating costs. According to a report by the Global System for Mobile Communications Association (GSMA), mobile network energy costs account for approximately 23% of operators' total costs. The majority of this energy consumption comes from the radio access network, particularly the active antenna unit (AAU), with data centers and fiber optic transmission contributing a smaller share. Radio access power consumption can be divided into two components: a dynamic component consumed only when data is being transmitted or received, and a static component consumed continuously to maintain the necessary operation of the radio access equipment, even when data transmission or reception is not in progress.

[0004] 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.

[0005] Summary of the Invention

[0006] Currently, due to the introduction of technologies such as large bandwidth / multi-antenna / multi-channel, base station energy consumption is relatively high, which has become one of the most urgent problems that global operators need to solve.

[0007] The current Release 18 (R18) phase introduces the topic of network energy conservation. Network energy conservation technologies can be categorized into time domain, frequency domain, spatial domain, and energy domain types, but in actual applications, it is more likely that two or more types of energy conservation technologies will be used in combination. For example, in terms of spatial domain energy conservation technologies, energy conservation can be achieved by adjusting spatial domain elements. The spatial domain elements here include logical antenna ports, transmitting and receiving units (TXRUs), transmit chains (Tx chains), array antenna factors, etc.; in terms of time domain energy conservation technologies, energy conservation can be achieved by switching cells on / off or reducing common channel / signal transmission; in terms of frequency domain energy conservation technologies, energy conservation can be achieved by switching bandwidth parts (BWPs). Through the above energy conservation technologies, network devices enter energy conservation mode (power saving mode or sleep mode). When a network device switches between normal (common) mode and energy-saving mode, it impacts terminal-related processing, including updating the channel state information (CSI) measurement method, updating CSI reporting, updating CSI-RS resources, and switching to partial bandwidth (BWP). These processes are the basis for the network device to schedule terminal devices for data reception and transmission. These processes also involve the network device's configuration and instructions to the terminal device, as well as the terminal device's reporting to the network device.

[0008] How to enable network devices and terminal devices to adapt to the impact of different modes without ambiguity is a key issue in whether network energy-saving technology can be applied in actual deployment and needs to be solved urgently.

[0009] In response to at least one of the above problems, an embodiment of the present application provides an information indication, an information receiving device, and a method. The network device changes the service mode and sends indication information to the terminal device, wherein the indication information indicates: CSI measurement mode update; and / or, CSI reporting update; and / or, CSI-RS resource update; and / or, BWP switching. As a result, the terminal device can adapt to the changed service mode without ambiguity through the indication information, and accurately determine information such as CSI measurement mode update and / or CSI reporting update and / or CSI-RS resource update and / or BWP switching, and further efficiently send subsequent uplink data or receive downlink data with the network device.

[0022] One of the beneficial effects of the embodiments of the present application is that a network device changes its service mode and sends indication information to a terminal device, wherein the indication information indicates: CSI measurement mode update; and / or CSI reporting update; and / or CSI-RS resource update; and / or BWP switching.

[0053] 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.

[0056] The current Release 18 (R18) phase introduces the topic of network energy conservation. Network energy conservation techniques can be categorized into time, frequency, spatial, and energy domains. However, in practice, a combination of two or more of these techniques is often employed. For example, spatial energy conservation techniques can achieve energy conservation by adjusting spatial elements, such as logical antenna ports, transmitting and receiving units (TXRUs), transmit chains, and array antenna factors. Time-domain energy conservation techniques can achieve energy conservation by switching cells on and off or reducing common signal transmissions. Frequency-domain energy conservation techniques can achieve energy conservation through methods such as bandwidth part (BWP) switching. These energy conservation techniques enable network devices to enter energy-saving modes (power-saving or sleep modes). Switching between normal and energy-saving modes impacts terminal-related processing, including updating the channel state information (CSI) measurement method, updating CSI reporting, updating CSI-RS resources, and switching bandwidth part (BWP). The above-mentioned related processing is the basis for the network device to schedule the terminal device to receive and send data. The above-mentioned related processing also involves the configuration and instruction of the network device to the terminal device and the reporting of the terminal device to the network device.

[0057] Taking spatial energy-saving technology as an example, the number of spatial elements can be adjusted to change to at least one energy-saving mode or normal (ordinary) mode. In the process of achieving energy saving by adjusting the number of spatial elements, the terminal device may change the CSI measurement method; in addition, in principle, the number of spatial elements cannot be less than the number of CSI-RS ports, otherwise the CSI-RS cannot be configured normally; in the process of achieving energy saving by adjusting the number of spatial elements, when the energy-saving mode is turned on or off, the number of spatial elements may be less than the number of CSI-RS ports, and the CSI-RS time-frequency space resources need to be updated.

[0058] Therefore, how to enable network devices and terminal devices to adapt to the impact of different modes without ambiguity is a key issue in whether network energy-saving technology can be applied in actual deployment and needs to be solved urgently. To address at least one of the above problems, the embodiments of the present application provide an information indication, information receiving device and method.

[0059] Embodiments of the first aspect

[0060] An embodiment of the present application provides an information indication method, which is described from the perspective of a network device.

[0061] FIG2 is a schematic diagram of an information indication method according to an embodiment of the present application. As shown in FIG2 , the method includes:

[0062] 201, network equipment changes service mode;

[0063] 202. The network device sends an indication message to the terminal device, wherein the indication message indicates: a channel state information (CSI) measurement method update; and / or a channel state information (CSI) reporting update; and / or a channel state information reference signal (CSI-RS) resource update; and / or a partial bandwidth (BWP) switching.

[0064] As a result, the terminal device can adapt to the changed service mode without ambiguity through the indication information, and accurately determine information such as CSI measurement method update and / or CSI reporting update and / or CSI-RS resource update and / or BWP switching, and further efficiently send subsequent uplink data or receive downlink data with the network device.

[0065] In some embodiments, the service mode includes a normal mode and / or at least one energy saving mode.

[0066] For example, "at least one energy-saving mode" may include at least one of the following modes: "energy-saving mode", "light energy-saving mode", "deep energy-saving mode", or "energy-saving transition mode", etc., and this application does not limit this; the above-mentioned "normal mode" can also be replaced with "normal mode"; the above-mentioned "energy-saving mode" can also be replaced with "power-saving mode" or "sleep mode" or "non-energy-saving mode" or "off mode" and other expressions, and this application does not limit this.

[0067] In some implementations, the service mode may be changed by changing "spatial elements" or "antenna modes." For example, by shutting down some "spatial elements," the network may be changed from "normal mode" to "energy-saving mode."

[0068] In some embodiments, the "spatial element" includes at least one of the following: a logical antenna port, a transmitting and receiving unit (TXRU), a transmit chain (Tx chain), or an array antenna factor; in some embodiments, the "spatial element" can also be directly replaced by "power saving mode"; "determining to turn on or off at least a portion of the spatial elements" can also be replaced by "determining to turn on or off the power saving mode"; or "determining to turn on or off at least a portion of the spatial elements" can also be replaced by "determining to activate or deactivate the power saving mode."

[0069] In some implementations, time-domain energy-saving technologies can be used to achieve energy conservation by switching cells on / off or reducing public signal transmissions. For example, by shutting down some cells, the network can be switched from "normal mode" to "energy-saving mode."

[0070] In some embodiments, in terms of frequency domain energy saving technology, energy saving can be achieved by switching bandwidth parts (BWPs), for example, by configuring a specific bandwidth part (BWP) to switch between "normal mode" and "energy saving mode".

[0071] In some embodiments, the network device also sends configuration information to the terminal device, wherein the configuration information configures a first timer associated with one of the at least one energy-saving modes; wherein the first timer sets the effective time of one of the at least one energy-saving modes.

[0072] For example, the network device sends the configuration information through high-layer signaling, such as RRC signaling, wherein the configuration information indicates the effect time of the energy-saving mode through a first timer, for example, 300 ms.

[0073] For example, after the terminal device reads the RRC signaling, it obtains the effective time of the energy-saving mode. The network device changes the service mode (for example, from normal mode to energy-saving mode) and sends an indication message to the terminal device. The terminal device updates the CSI measurement method, and / or CSI reporting update, and / or CSI-RS resource update, and / or BWP switching, and restores the normal mode after 300ms. The specific contents indicated by the indication message will be explained separately later.

[0074] In some implementations, the network device sends the indication information via semi-static signaling or dynamic signaling.

[0075] For example, if RRC signaling is used to send indication information, such as using an RRC reconfiguration process, which is implemented in milliseconds, excessive delay is not conducive to supporting dynamic energy-saving modes, which can be at the symbol or time slot level (less than milliseconds); for another example, under normal circumstances, a user's CSI-RS resources and CSI measurements do not need to be changed frequently, but during energy-saving operations, normal mode and energy-saving mode will switch frequently. If the RRC signaling process is used, it will bring a lot of overhead and cause waste of system resources. Therefore, the above-mentioned embodiment of the present application can further reduce the delay and overhead of signaling by sending the indication information through semi-static signaling or dynamic signaling, and can support the switching of dynamic energy-saving modes.

[0076] In some embodiments, the semi-static signaling may be MAC CE signaling; the dynamic signaling may be downlink control information (DCI). For example, the dynamic signaling is DCI, and the indication information is carried by the DCI. The DCI may be a DCI format newly added to the energy-saving mode, or the existing DCI format may be reused. This application does not impose any restrictions on this. For example, when a new DCI format is introduced, the DCI format may be scrambled by introducing a new Radio Network Temporary Identity (RNTI), such as ES-RNTI (energy saving-RNTI). Specific time-frequency resources may also be allocated for the new DCI format so that the terminal device can identify the DCI. This application does not impose any restrictions on this.

[0077] In some embodiments, the indication information can be sent to the terminal device together with the signaling indicating the change of service mode; for example, the terminal device is instructed to activate / deactivate the "energy saving mode" through DCI, and the indication information can be carried together with the DCI; optionally, the indication information can also be sent separately from the signaling indicating the change of service mode, and this application does not limit this.

[0078] In some embodiments, the semi-static signaling or the dynamic signaling is group signaling, and the network device sends indication information to multiple terminal devices through the group signaling; or, the semi-static signaling or the dynamic signaling is terminal device specific (UE specific) signaling, and the network device sends indication information to one terminal device through the user equipment specific signaling.

[0079] In some implementations, the indication information indicates: CSI measurement mode update; and / or CSI reporting update; and / or CSI-RS resource update; and / or BWP switching. The indications of the above indication information are schematically described below.

[0080] The following describes in detail how to instruct the CSI measurement mode to update.

[0081] For example, the "CSI measurement method" is that the terminal device performs "merging processing" or "not combining processing" on the CSI measurement results; for example, "combining processing" can also be replaced by "combining averaging" or "smoothing filtering"; among them, the specific implementation methods of "combining processing" or "smoothing filtering" can refer to the existing technology, and this application does not limit this.

[0082] For example, in "normal mode" ("non-energy-saving mode"), the terminal device usually combines all CSI measurement results; however, when the "energy-saving mode" is turned on, the transmission power of the channel state indication reference signal (CSI-RS) will change, and the most recent CSI measurement method after the change from "normal mode" to "energy-saving mode" should also change accordingly to reflect the channel quality status in real time. For example, when the "normal mode" is changed to "energy-saving mode", if the terminal device still combines the CSI measurement results, it may combine the CSI measurement results of the "normal mode" and "energy-saving mode", which will cause the combined CSI measurement results to fail to truly reflect the channel status of the energy-saving mode. The implementation method of the present application can enable the terminal device to obtain the change or non-change of the CSI measurement method in a timely manner through the indication information, thereby enabling more accurate CSI measurement.

[0083] In some implementations, the network device indicates whether the CSI measurement mode is changed or not through indication information indicating an update of the CSI measurement mode and / or a first timer.

[0084] In some embodiments, when the network device changes its service mode, the indication information indicates that the CSI measurement method is changed through a value of one or more bits, and / or indicates that the CSI measurement method is not changed through another value of the one or more bits.

[0085] In some implementations, when the semi-static signaling or dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks.

[0086] For example, each block corresponds to a terminal device, and the starting position and / or size of each block is configured by high-layer signaling.

[0087] FIG3 is an example diagram of indication information according to an embodiment of the present application.

[0088] For example, each block represents the indication information of a terminal device, and the starting position and / or size of each block is given by high-level parameters. For example, high-level parameters in existing standards can be used, or new high-level parameters can be introduced. This application does not impose any restrictions on this.

[0089] Taking each block as 1 bit as an example, the network device can use 1 bit to indicate to a specific terminal device whether the CSI measurement method is changed or not. For example, if the bit is "1", the CSI measurement method is changed, or in other words, CSI measurement merging processing is not performed; if the bit is "0", the CSI measurement method is not changed, or in other words, CSI measurement merging processing is performed.

[0090] For example, for five terminal devices, the specific content of the indication information is "11010", which means: for the first, second, and fourth terminal devices, CSI measurement merging processing is not performed; for the third and fifth terminal devices, CSI measurement merging processing is performed. Taking the third terminal device as an example, the third terminal device obtains the indication information of a total of 5 bits through high-layer signaling, where the size of each block is 1 bit. Therefore, the third terminal device can determine that the third bit (with a value of "0") is the indication bit of the third terminal device.

[0091] In some implementations, if the CSI measurement method of a terminal device is changed, the indication information carries the block corresponding to the terminal device; if the CSI measurement method of the terminal device is not changed, the indication information does not carry the block corresponding to the terminal device. For example, if the terminal device does not read the relevant fields of the indication information through higher-layer signaling, it is considered that the CSI measurement method has not been changed and the original CSI measurement method is still used.

[0092] In some implementations, when the semi-static signaling or dynamic signaling is terminal device-specific signaling, for example, the network device may use one bit to indicate whether the CSI measurement mode is changed or not. For example, if the bit is "1," the CSI measurement mode is changed, or in other words, CSI measurement merging is not performed; if the bit is "0," the CSI measurement mode is not changed, or in other words, CSI measurement merging is performed.

[0093] The above bit content is only for exemplary purposes and can also be set to "0" to change the CSI measurement method, or in other words, not perform CSI measurement merging processing; the bit is "1" to not change the CSI measurement method, and this application does not impose any restrictions on this.

[0094] In some embodiments, the terminal device changes the CSI measurement mode after the first timer expires.

[0095] For example, the network device sends the configuration information through high-layer signaling, such as RRC signaling, where the configuration information indicates the effective time of the energy-saving mode. For example, the terminal device obtains the effective time of the energy-saving mode after reading the RRC signaling, the network device changes the service mode (for example, from normal mode to energy-saving mode) and sends indication information to the terminal device (using the above-mentioned indication method), the terminal device updates the CSI measurement method, for example, when changing from normal mode to energy-saving mode, no merging processing is performed, and normal mode is restored after 300ms, and the CSI measurement method is changed, for example, CSI measurement when 300ms expires is not merging processing.

[0096] In this way, the terminal device can obtain the specific content of the indication information and can perform CSI measurement more accurately.

[0097] The following describes in detail how to instruct the CSI to report an update.

[0098] In some implementations, the network device activates / deactivates at least one CSI report through indication information indicating CSI report update and / or a first timer.

[0099] In some embodiments, when the network device changes the service mode, the indication information indicates activation of the first CSI reporting and / or deactivation of the second CSI reporting, wherein the first CSI reporting and / or the second CSI reporting are configured by high-layer information.

[0100] In some embodiments, the first CSI report and / or the second CSI report belongs to a first CSI reporting list, and the first CSI reporting list includes a CSI reporting configuration index (CSI-ReportConfigId), wherein the first CSI reporting list and the CSI reporting configuration index (CSI-ReportConfigId) are configured by high-level information.

[0101] For example, each CSI report corresponds to a CSI reporting configuration index (CSI-ReportConfigId). For example, the CSI report corresponding to the CSI reporting configuration index (CSI-ReportConfigId)=0 is: CSI 0.

[0102] For example, which CSI reports are included in the first CSI reporting list are configured through high-layer signaling. For example, the first CSI reporting list configured by high-layer signaling contains 5 CSI reports, corresponding to "CSI 0"-"CSI 4" respectively; the terminal device determines which specific CSI report to activate / deactivate based on the indication information, and the specification will further illustrate with examples in combination with the implementation method in the subsequent content.

[0103] In some implementations, the CSI reporting configuration index (CSI-ReportConfigId) included in the first CSI reporting list is associated with a change in at least one of the following information:

[0104] The CSI reporting period and offset (offset), for example, are indicated by the following fields in higher layer signaling: "CSI-ReportPeriodicityAndOffset", "reportSlotConfig", and "reportSlotOffsetList";

[0105] The resources used for CSI reporting are indicated, for example, by the following field in higher layer signaling: "pucch-CSI-ResourceList";

[0106] The period and offset of the CSI-RS Resource bound to the CSI report are indicated, for example, by the following fields in the higher layer signaling: "ResourceConfig"; or CSI-

[0107] The time-frequency resources of the CSI-RS Resource bound to the CSI report are indicated, for example, by the following field "CSI-ResourceConfig" in the higher-layer signaling.

[0108] For example, the CSI reporting period in energy-saving mode can be longer, for example, the CSI reporting period in normal mode is 40ms, and the CSI period in energy-saving mode is 80ms; for example, the high layer configures the CSI 0 period to be 80ms, the CSI 1 period to be 40ms, and the first CSI reporting list includes CSI 0 and CSI 1. After the service mode is changed to energy-saving mode, the indication information can indicate the activation of CSI 0 (first CSI reporting) and the deactivation of CSI 1 (second CSI reporting). The specification will further illustrate with examples in combination with the implementation methods in the subsequent content.

[0109] For another example, the CSI-RS resource bound to the CSI report in energy-saving mode is CSI-RS 16port, and the CSI-RS resource bound to the CSI report in normal mode is CSI-RS 32port. For example, the upper layer configures CSI 0 to be bound to CSI-RS 0 of 32port, CSI 1 to be bound to CSI-RS 1 of 16port, and the first CSI reporting list includes CSI 0 and CSI 1. After the service mode is changed to energy-saving mode, the indication information can indicate the activation of CSI 1 (first CSI reporting) and the deactivation of CSI 0 (second CSI reporting). Activating CSI 1 also means activating the CSI-RS 1 bound to 16port, and deactivating CSI 0 also means deactivating the CSI-RS 0 bound to 32port.

[0110] In some implementations, for a specific CSI report, the indication information indicates activation of the CSI report through one value of one or more bits, and indicates deactivation of the CSI report through another value of the one or more bits.

[0111] In some embodiments, when the semi-static signaling or dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks; wherein each block corresponds to a terminal device, the starting position and / or size of each block is configured by high-level signaling, each block includes one or more bits, each block indicates the first CSI reporting list of the terminal device, and each bit in each block corresponds to the CSI report in the first CSI reporting list.

[0112] For example, still taking the bitmap of multiple blocks shown in Figure 3 as an example, each block represents the indication information of a terminal device, and the starting position and / or size of each block is given by high-level parameters. For example, high-level parameters in existing standards can be used, or new high-level parameters can be introduced. This application does not impose any restrictions on this.

[0113] For example, each block corresponds to the first CSI reporting list of a specific terminal device, and each block includes X bits, where each bit of the X bits corresponds to the activation / deactivation status of a CSI report in the first CSI reporting list, and the list can be given by high-level parameters.

[0114] Taking a specific terminal device as an example, for example, the high-level parameters configure the first CSI reporting list to contain 5 CSI reports, corresponding to "CSI 0"-"CSI 4" respectively, and the activation / deactivation status of each CSI report is indicated by 5 bits, for example, "0" represents deactivation of CSI reporting, and "1" represents activation of CSI reporting; for example, the high-level parameters configure the CSI period of "CSI 0" (first CSI reporting) to be 80m, and the CSI period of "CSI 1"-"CSI 4" (second CSI reporting) to be 40m, and "10000" can be sent to the user equipment, which means activating "CSI 0" and deactivating "CSI 1"-"CSI 4".

[0115] For example, for five terminal devices, the indication information is "'10000''10100''00011''00100''10001'"; taking the second terminal device as an example, the second terminal device obtains the indication information through high-layer signaling, which is a total of 25 bits, with the starting position being the 6th bit, and the size of the terminal indication information is 5 bits, that is, the sixth to tenth bits are the indication bits of the second terminal device; wherein, '10100' indicates that for the second terminal device, "CSI 0" (first CSI report) and "CSI 2" (first CSI report) are activated, and "CSI 1" (second CSI report), "CSI 3" (second CSI report), and "CSI 4" (second CSI report) are deactivated. The above is only an exemplary description. For example, the first CSI reporting list for different terminal devices may be different.

[0116] In some embodiments, if the CSI reporting activation / deactivation status of a terminal device requires updating, the indication information carries the block corresponding to the terminal device; if the CSI reporting activation / deactivation status of a terminal device does not require updating, the indication information does not carry the block corresponding to the terminal device. For example, if the terminal device does not read the relevant fields of the indication information through higher-layer signaling, it is considered that the CSI reporting activation / deactivation status does not require updating.

[0117] The above bit content is only for illustrative purposes. It can also be set to "0" to represent activation of CSI reporting and "1" to represent deactivation of CSI reporting. This application does not impose any restrictions on this.

[0118] In some embodiments, the first CSI reporting and / or the second CSI reporting includes: periodic CSI reporting, semi-continuous CSI reporting, or non-periodic CSI reporting; for example, the specific content of periodic CSI reporting, semi-continuous CSI reporting, or non-periodic CSI reporting can be referred to the prior art, and this application does not limit this.

[0119] FIG4 is an example diagram of CSI reporting according to an embodiment of the present application.

[0120] For example, for a specific terminal device, when the terminal device is in normal mode, its configured CSI report is "CSI 0", and its bound CSI-RS resource is "CSI-RS 0"; when the terminal device is in energy-saving mode, its configured CSI report is "CSI 1", and its bound CSI-RS resource is "CSI-RS 1"; for example, in combination with the above-mentioned method of updating CSI reporting, when the service mode is changed to energy-saving mode, the indication information sent by the network device is "…'01000'….", and the corresponding updated activated CSI report is "CSI 1"; for example, when the service mode is changed to normal mode, the indication information sent is "…'10000'….", and the corresponding updated activated CSI report is "CSI 0".

[0121] In some embodiments, when semi-static signaling or dynamic signaling is terminal device-specific signaling, for example, the network device may indicate a first CSI reporting list using X bits; each bit in the X bits indicates a specific activation or deactivation of CSI reporting, for example, "1" indicates activation of CSI reporting; "0" indicates deactivation of CSI reporting. For example, the content of each block in the above embodiment is used as the specific content of terminal device-specific signaling and then sent to a specific terminal device. For the specific indication method, please refer to the above embodiment and will not be repeated here.

[0122] In some embodiments, when the service mode of the terminal device changes, the terminal device starts a first timer and suspends the CSI reporting before the service mode changes; and the terminal device resumes the CSI reporting before the service mode changes after the first timer times out.

[0123] For example, the network device sends the configuration information through high-layer signaling, such as RRC signaling, wherein the configuration information indicates the effective time of the energy-saving mode. For example, after the terminal device reads the RRC signaling, it obtains the effective time of the energy-saving mode, the network device changes the service mode (for example, from the normal mode to the energy-saving mode) and sends indication information to the terminal device (using the above-mentioned indication method), the terminal device updates the activated / deactivated CSI reporting and suspends the activated / deactivated CSI reporting in the normal mode, and resumes the normal mode and the activated / deactivated CSI reporting in the normal mode after 300ms, that is, after the first timer expires.

[0124] In this way, the terminal device can obtain the specific content of the indication information and determine the CSI reporting update.

[0125] The following describes in detail how to instruct CSI-RS resource update.

[0126] In some implementations, the network device activates / deactivates at least one CSI-RS resource through indication information indicating CSI-RS resource update and / or a first timer.

[0127] In some embodiments, when a network device changes a service mode, the indication information indicates activation of a first CSI-RS resource and / or deactivation of a second CSI-RS resource, wherein the first CSI-RS resource and / or the second CSI-RS resource are configured by high-layer information; wherein the first CSI-RS resource and / or the second CSI-RS resource are the same or different.

[0128] In some embodiments, the first CSI-RS resource and / or the second CSI-RS resource belongs to a first CSI-RS resource set, wherein the first CSI-RS resource set includes CSI-RS resources (CSI-RS resource) and / or, CSI-RS ports (CSI-RS port); wherein the index of the first CSI-RS resource set and the number and index of CSI-RS resources (CSI-RS resource) included in the first CSI-RS resource set, and / or, the number and / or index of the CSI-RS ports (CSI-RS port) are configured by high-level information.

[0129] For example, high-layer signaling configures the first CSI-RS resource set and its index, and the first CSI-RS resource set includes multiple CSI-RS resources and multiple CSI-RS ports and related configurations, wherein the related configurations of multiple CSI-RS resources and multiple CSI-RS ports can be referred to the prior art, and this application does not limit this.

[0130] In the following, it is taken as an example that the first CSI-RS resource and / or the second CSI-RS resource belongs to a first CSI-RS resource set, wherein the first CSI-RS resource set includes CSI-RS resources.

[0131] In some embodiments, for a specific CSI-RS resource, the indication information indicates activation of the CSI-RS resource through one value of one or more bits, and the indication information indicates deactivation of the CSI-RS resource through another value of one or more bits.

[0132] In some implementations, the CSI-RS resource includes a group of CSI-RS resources or one CSI-RS resource, and the group of CSI-RS resources is configured by higher layer signaling.

[0133] In some embodiments, when the semi-static signaling or dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks; each block corresponds to a terminal device, and the starting position and / or size of each block is configured by high-level signaling; each bit corresponds to a group of CSI-RS resources (CSI-RS resource) or a CSI-RS resource (CSI-RS resource) of the terminal device, and the number of bits is configured by high-level signaling.

[0134] For example, still taking the bitmap of multiple blocks shown in Figure 3 as an example, each block represents the indication information of a terminal device, and the starting position and / or size of each block is given by high-level parameters. For example, high-level parameters in existing standards can be used, or new high-level parameters can be introduced. This application does not impose any restrictions on this.

[0135] For example, each block corresponds to the activation / deactivation status of each CSI-RS resource in a CSI-RS resource set of a specific terminal device. For example, each block includes X bits, where each bit of the X bits corresponds to the activation / deactivation status of the CSI-RS resource. In some embodiments, the specific settings of the CSI-RS resource set and its corresponding CSI-RS resource can be referred to the prior art, and this application is not limited thereto.

[0136] For example, the first CSI-RS resource set (CSI-RS resource set) includes 4 CSI-RS resources (CSI-RS resource), and the activation / deactivation status of each CSI-RS resource (CSI-RS resource) is indicated by 4 bits. For example, "0" represents deactivation of the CSI-RS resource (CSI-RS resource), and "1" represents activation of the CSI-RS resource (CSI-RS resource); "1010" means activating "CSI-RS resource 0" (first CSI-RS resource) and "CSI-RS resource 2" (first CSI-RS resource), and deactivating "CSI-RS resource 1" (second CSI-RS resource) and "CSI-RS resource 3" (second CSI-RS resource).

[0137] For example, for two terminal devices, the indication information is "'1010' '0101'"; taking the first terminal device as an example, the first terminal device obtains the indication information through high-layer signaling, which is a total of 8 bits, starting at the 1st bit, and continues for 4 bits, that is, the first to fourth bits are the indication bits of the first terminal device; among them, '1010' indicates that for the first terminal device, "CSI-RS resource 0" and "CSI-RS resource 2" are activated, and "CSI-RS resource 1" and "CSI-RS resource 3" are deactivated.

[0138] Optionally, the indication information may also indicate the activation / deactivation status of a group of CSI-RS resources (CSI-RS resource), for example, "CSI-RS resource 0" and "CSI-RS resource 2" are group 0 (Group 0); "CSI-RS resource 1" and "CSI-RS resource 3" are group 1 (Group 1); for two terminal devices, the indication information is "'10' '01'"; taking the first terminal device as an example, the first terminal device obtains the indication information through high-layer signaling, which is a total of 4 bits, wherein the size of each block is 2 bits and "CSI-RS resource 0" and "CSI-RS resource 2" are group 0 (Group 0), "CSI-RS resource 1" and "CSI-RS resource 3" are group 1 (Group 1), and the first to second bits are the indication bits of the first terminal device; wherein, '10' indicates that for the first terminal device, "CSI-RS resource 0" and "CSI-RS resource 2" are activated, and "CSI-RS resource 1" and "CSI-RS resource 3" are deactivated.

[0139] In some embodiments, if the activation / deactivation status of the CSI-RS resource (CSI-RS resource) of the terminal device needs to be updated, the indication information carries the block corresponding to the terminal device; if the activation / deactivation status of the CSI-RS resource (CSI-RS resource) of the terminal device does not need to be updated, the indication information does not carry the block corresponding to the terminal device. For example, if the terminal device does not read the relevant fields of the indication information through high-layer signaling, it is considered that the activation / deactivation status of the CSI-RS resource (CSI-RS resource) does not need to be updated.

[0140] The above bit content is only for exemplary description, and can also be set to "0" to represent activation of CSI-RS resources (CSI-RS resource) and "1" to represent deactivation of CSI-RS resources (CSI-RS resource). This application does not limit this.

[0141] FIG5 is an example diagram of CSI-RS resource update according to an embodiment of the present application.

[0142] As shown in FIG5 , for example, a 32-port CSI-RS can be supported using CDM-4 and four resources, where one CDM-4 resource occupies eight resource elements (REs). CDM-4 can refer to prior art and is not limited in this application. In normal mode, a specific terminal device uses a 32-port CSI-RS. In energy-saving mode, the terminal device uses a 16-port CSI-RS. For example, when a network device shuts down some spatial elements, the terminal device's CSI-RS resources change from activating "Resource 1 - Resource 4" in FIG5 to activating "Resource 1, Resource 3" and deactivating "Resource 2, Resource 4." This enables the update of 32-port CSI-RS resources to 16-port CSI-RS resources, for example, using the aforementioned indication method, which is not repeated here.

[0143] In some embodiments, when the semi-static signaling or dynamic signaling is terminal device specific signaling. For example, the network device may indicate the activation / deactivation status of the CSI-RS resource (CSI-RS resource) contained in a CSI-RS resource set (CSI-RS resource set) through X bits; each bit in the X bits indicates the activation / deactivation status of a specific CSI-RS resource (CSI-RS resource), for example, "1" is to activate the CSI-RS resource (CSI-RS resource); "0" is to deactivate the CSI-RS resource (CSI-RS resource); optionally, the network device may indicate the activation / deactivation status of multiple groups of CSI-RS resources (CSI-RS resource) contained in a CSI-RS resource set (CSI-RS resource set) through X bits. For example, the content of each block of the above embodiment is used as the specific content of the terminal device specific signaling and then sent to a specific terminal device. For the specific indication method, please refer to the above embodiment, which will not be repeated here.

[0144] In some embodiments, the terminal device suspends the CSI-RS resources before the service mode is changed after the first timer expires; and the terminal device resumes the CSI-RS resources before the service mode is changed after the first timer expires.

[0145] For example, the network device sends the configuration information through high-layer signaling, such as RRC signaling, where the configuration information indicates the effective time of the energy-saving mode. For example, after the terminal device reads the RRC signaling, it obtains the effective time of the energy-saving mode, the network device changes the service mode (for example, from the normal mode to the energy-saving mode) and sends indication information to the terminal device (using the above-mentioned indication method), the terminal device updates the activated / deactivated CSI-RS resources and suspends the CSI-RS resources activated / deactivated in the normal mode, and resumes the normal mode after the first timer expires after 300ms, and resumes the activated / deactivated CSI-RS resources in the normal mode.

[0146] Thus, the terminal device can obtain the specific content of the indication information and can determine the updated activated / deactivated CSI-RS resource (CSI-RS resource).

[0147] In the following, it is taken as an example that the first CSI-RS resource and / or the second CSI-RS resource belongs to a first CSI-RS resource set, wherein the first CSI-RS resource set includes a CSI-RS port.

[0148] In some implementations, the indication information indicates deactivation of the CSI-RS port through one value of one or more bits, and indicates activation of the CSI-RS port through another value of the one or more bits.

[0149] In some implementations, the CSI-RS port includes a group of CSI-RS ports or one CSI-RS port; the group of CSI-RS ports is configured by higher layer signaling.

[0150] In some embodiments, when the semi-static signaling or dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks; wherein each block corresponds to a terminal device, and the starting position and / or size of each block is configured by high-level signaling; wherein each block includes one or more bits, each bit corresponds to a group of CSI-RS ports or a CSI-RS port of the terminal device, and the number of bits is configured by high-level signaling.

[0151] For example, still taking the bitmap of multiple blocks shown in Figure 3 as an example, each block represents the indication information of a terminal device, and the starting position and / or size of each block is given by high-level parameters. For example, high-level parameters in existing standards can be used, or new high-level parameters can be introduced. This application does not impose any restrictions on this.

[0152] For example, each block corresponds to the activation / deactivation state of a CSI-RS port of a specific terminal device. For example, each block includes X bits, where each of the X bits corresponds to the activation / deactivation state of the CSI-RS port. In some embodiments, the specific setting of the CSI-RS port can be referred to in the prior art, and this application is not limited thereto.

[0153] Optionally, each block instance may also include CSI-RS resource (CSI-RS resource) related information, for example, including a T bit (T may be equal to 0), wherein the T bit indicates the CSI-RS resource group (CSI-RS resource set) and / or CSI-RS resource (CSI-RS resource) corresponding to the CSI-RS port (port). Optionally, when T=0, the CSI-RS resource group (CSI-RS resource set) and / or CSI-RS resource (CSI-RS resource) corresponding to the CSI-RS port (port) is indicated by high-level information.

[0154] The following description is made by taking T=0, that is, not indicating the CSI-RS resource set and / or CSI-RS resource corresponding to the CSI-RS port, as an example.

[0155] For example, a terminal device can be configured with 32 CSI-RS ports, and the activation / deactivation status of the CSI-RS port is indicated by 32 bits. For example, "0" represents deactivation of the CSI-RS port, and "1" represents activation of the CSI-RS port; "0000000000000000111111111111111111" means activation of "CSI-RS port 16" - "CSI-RS port 31", and deactivation of "CSI-RS port 0" - "CSI-RS port 15"; optionally, the indication information can also indicate the activation / deactivation status of a group of CSI-RS ports, and this group of CSI-RS ports can be one or more CDM groups, for example, "CSI-RS port 0" - "CSI-RS port 15" is group 0 (Group 0); "CSI-RS port 16" - "CSI-RS port 31" is group 1 (Group 1), or a total of 4 CDM groups for the CSI-RS32 port, "CDM Group 0" and "CDM Group 1" are Group 0 (Group 0), and "CDM Group 2" and "CDM Group 3" are Group 1 (Group 1).

[0156] For example, for two terminal devices, the indication information is "'10' '01'"; taking the first terminal device as an example, the first terminal device obtains the indication information through high-layer signaling, which is a total of 4 bits. The starting position corresponding to the terminal device is the 1st bit, a total of 2 bits, and "CSI-RS port 0" - "CSI-RS port 15" is group 0 (Group0); "CSI-RS port 16" - "CSI-RS port 31" is group 1 (Group 1), and the first to second bits are the indication bits of the first terminal device; among them, '10' indicates that for the first terminal device, activate "CSI-RS port 0" - "CSI-RS port 15", and deactivate "CSI-RS port 16" - "CSI-RS port 31".

[0157] In addition, for the case where T is not equal to 0, the above-mentioned activation / deactivation of the CSI-RS port and the above-mentioned activation / deactivation of the CSI-RS resource can be combined for indication, which is not repeated in this application.

[0158] In some embodiments, if the activation / deactivation status of a CSI-RS port of a terminal device needs to be updated, the indication information carries the block corresponding to the terminal device; if the CSI-RS port of the terminal device does not need to be updated, the indication information does not carry the block corresponding to the terminal device. For example, if the terminal device does not read the relevant field of the indication information through high-layer signaling, it is considered that the activation / deactivation status of the CSI-RS port does not need to be updated.

[0159] The above bit content is only for illustrative purposes. It can also be set to "0" to represent activation of the CSI-RS port and "1" to represent deactivation of the CSI-RS port. This application does not limit this.

[0160] FIG6 is an example diagram of CSI-RS port update according to an embodiment of the present application.

[0161] As shown in FIG6 , for a 32-port CSI-RS, for example, 4 CDM-8s and 1 resource can be used to support the 32-port CSI-RS, wherein one CDM-8 resource occupies 32 resource elements (REs). The CDM-8 can refer to the prior art, and this application does not limit this. In normal mode, a specific terminal device uses a 32-port CSI-RS, and in energy-saving mode, the terminal device uses a 16-port CSI-RS. For example, when the network device turns off some airspace elements, the CSI-RS resource of the terminal device is changed from "activate CSI-RS ports 0-31" in FIG6 to "activate CSI-RS ports 0-15". Thus, the update from 32-port CSI-RS to 16-port CSI-RS can be achieved; for example, the above-mentioned indication method is used, and no repetitive description is given here.

[0162] In some embodiments, when semi-static signaling or dynamic signaling is terminal device-specific signaling. For example, the network device may indicate the activation / deactivation status of the CSI-RS port through X bits; each bit in the X bits indicates the activation / deactivation status of a specific CSI-RS port, for example, "1" is to activate the CSI-RS port; "0" is to deactivate the CSI-RS resource (CSI-RS resource); optionally, the network device may indicate the activation / deactivation status of multiple groups of CSI-RS ports through X bits. For example, the content of each block of the above embodiment is used as the specific content of the terminal device-specific signaling and then sent to a specific terminal device. For the specific indication method, please refer to the above embodiment, which will not be repeated here.

[0163] In some embodiments, the terminal device suspends the CSI-RS port before the service mode is changed after the first timer expires; and the terminal device resumes the CSI-RS port before the service mode is changed after the first timer expires.

[0164] For example, the network device sends the configuration information through high-layer signaling, such as RRC signaling, wherein the configuration information indicates the effective time of the energy-saving mode. For example, after the terminal device reads the RRC signaling, it obtains the effective time of the energy-saving mode, the network device changes the service mode (for example, enters the energy-saving mode from the normal mode) and sends indication information to the terminal device (using the above-mentioned indication method), the terminal device updates the activation / deactivation CSI-RS port and suspends the activation / deactivation CSI-RS port in the normal mode, and restores the normal mode after the first timer expires after 300ms, and restores the activated / deactivated CSI-RS port in the normal mode.

[0165] Thus, the terminal device can obtain the specific content of the indication information and can determine the updated activated / deactivated CSI-RS port (CSI-RS port).

[0166] The following describes in detail how to instruct BWP switching.

[0167] In some implementations, the network device indicates the BWP after the service mode is changed through indication information indicating BWP switching and / or a first timer.

[0168] In some implementations, when the network device changes its service mode, the indication information indicates a BWP index after the service mode is changed; wherein the BWP index is configured by high-layer information.

[0169] In some implementations, the BWP index is associated with a CSI reporting configuration index (CSI-ReportConfigId); wherein the CSI reporting configuration index (CSI-ReportConfigId) associated with the BWP index is configured by higher layer information.

[0170] In some embodiments, when the network device changes its service mode, it switches to the BWP corresponding to the BWP index after the service mode change is activated, and at the same time activates the CSI report associated with the associated CSI reporting configuration index (CSI-ReportConfigId), and deactivates the CSI report associated with the CSI reporting configuration index (CSI-ReportConfigId) associated with the BWP index before the service mode change.

[0171] In some embodiments, when the semi-static signaling or dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks; each block corresponds to a terminal device, and the starting position and / or size of each block is configured by high-level signaling; each block includes one or more bits, indicating the index (index) of the BWP to which the terminal device should switch.

[0172] For example, still taking the bitmap of multiple blocks shown in Figure 3 as an example, each block represents the indication information of a terminal device, and the starting position and / or size of each block is given by high-level parameters. For example, high-level parameters in existing standards can be used, or new high-level parameters can be introduced. This application does not impose any restrictions on this.

[0173] For example, each block corresponds to the index of the BWP to be switched by the terminal device when at least a portion of the spatial domain elements is turned on or off. For example, each block includes X bits, which correspond to the index of a BWP. In some embodiments, the setting of the BWP and its index can be referred to in the prior art, and this application is not limited thereto.

[0174] For example, a terminal device is configured with 4 BWPs, and the indication information indicates the BWP index to be switched through 2 bits, for example, "00" represents switching to BWP 0, "01" represents switching to BWP 1, "10" represents switching to BWP 2, and "11" represents switching to BWP 3. For example, the higher-layer signaling configures BWP 0 to be associated with CSI 0, and BWP 1 to be associated with CSI 1. After the service mode is changed to the energy-saving mode, for example, when the indication information indicates "00", CSI 0 is activated and the CSI reporting in the normal mode of the terminal device is deactivated, for example, CSI 1 in the normal mode configured by the higher-layer signaling is deactivated.

[0175] For example, for two terminal devices, when the service mode changes, the indication information is "'10' '01'"; taking the first terminal device as an example, the first terminal device obtains the indication information totaling 4 bits through high-layer signaling, where the size of each block is 2 bits, and the first to second bits are the indication bits of the first terminal device; where '10' indicates that for the first terminal device, switch to BWP 2.

[0176] In some implementations, if the terminal device's BWP requires switching, the indication information carries the block corresponding to the terminal device; if the terminal device's BWP does not require switching, the indication information does not carry the block corresponding to the terminal device. For example, if the terminal device does not read the relevant field of the indication information through higher-layer signaling, it is considered that the terminal device's BWP does not require switching.

[0177] In some embodiments, the terminal device suspends the BWP index before the service mode is changed; and the terminal device restores the BWP index before the service mode is changed after the first timer expires.

[0178] For example, the network device sends the configuration information through high-layer signaling, such as RRC signaling, where the configuration information indicates the effective time of the energy-saving mode.
