Description

[Technical Field]

[0001] FIELD OF THE INVENTION Embodiments of the present invention relate to the field of communications technology. [Background technology]

[0002] Network energy efficiency is important for environmental sustainability, reducing environmental impact (greenhouse gas emissions), and reducing operational costs. With the widespread adoption of 5th Generation Mobile Communication Technology (5G) across industries and geographic regions, networks are becoming denser, using more antennas, greater bandwidth, and more frequency bands to handle more advanced services and applications, which require significantly higher data rates. The need to control the environmental impact of 5G necessitates the development of new solutions to improve network energy efficiency.

[0003] Energy consumption is an important part of the operational costs of telecommunications operators. According to a report by the Global System for Mobile Communications Association (GSMA), the energy costs of mobile networks account for approximately 23% of a telecommunications operator's total costs. The majority of energy consumption is due to the radio access network, especially active antenna elements (AAUs), with data centers and optical fiber transmission accounting for a relatively small proportion. Radio access energy consumption can be divided into a dynamic part, which is consumed only while data is being transmitted / received, and a static part, which is consumed constantly to maintain the necessary operation of the radio access equipment even when no data is being transmitted / received.

[0004] The above description of the background art is merely for the purpose of explaining the configuration of the present invention more clearly and completely, and is provided for the understanding of those skilled in the art. These configurations described in the background art of the present invention should not be construed as being well known to those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0005] Currently, the introduction of technologies such as large bandwidth, multi-antenna, and multi-channel has increased the energy consumption of base stations, making this one of the most pressing issues that telecommunications operators around the world need to address.

[0006] The current Release 18 (R18) stage introduces the topic of network energy saving. Network energy saving technologies can be classified into time domain, frequency domain, spatial domain, and energy domain types. However, in practical applications, two or more types of energy saving technologies are often combined. For example, spatial domain energy saving technologies can achieve energy saving by adjusting spatial domain elements. Here, spatial domain elements include logical antenna ports, transmitting and receiving units (TXRUs), transmit chains, and array antenna factors. Time domain energy saving technologies can achieve energy saving by cell ON / OFF or reducing common channel / signal transmissions. Frequency domain energy saving technologies can achieve energy saving by bandwidth part (BWP) switching, etc. These energy saving technologies enable network devices to enter energy saving modes (power saving mode or sleep mode). When the network device changes between the normal mode and the energy saving mode, it affects the related processes of the terminal, including updating the channel state information (CSI) measurement mode, updating the channel state information (CSI) report, updating the channel state information reference signal (CSI-RS) resource, switching the bandwidth portion (BWP), etc. The above related processes are the basis for the network device to schedule the terminal device for data reception and data transmission. The above related processes relate to the configuration, instruction, and reporting of the terminal device by the network device.

[0007] How to enable network devices and terminal devices to adapt to the effects of different modes without ambiguity is a key issue for whether network energy-saving technologies can be applied in actual deployment, and needs to be resolved urgently.

[0008] In consideration of at least one of the above problems, embodiments of the present invention provide an information indication device, an information receiving device, and a method thereof. A network device changes a service mode and transmits indication information to a terminal device, where the indication information indicates updating a CSI measurement mode, updating a CSI report, updating a CSI-RS resource, and / or switching a BWP. This enables the terminal device to unambiguously adapt to the changed service mode using the indication information and accurately determine information such as updating a CSI measurement mode, updating a CSI report, updating a CSI-RS resource, and / or switching a BWP, thereby efficiently transmitting uplink data or receiving downlink data with the network device.

[0010] Another aspect of an embodiment of the present invention provides an information receiving device, which is applied to a terminal device, including: a receiving unit that receives instruction information; and a decision unit that decides to update a channel state information (CSI) measurement mode, and / or update a channel state information (CSI) report, and / or update a channel state information reference signal (CSI-RS) resource, and / or switch a bandwidth portion (BWP) based on the instruction information.

[0011] Another aspect of an embodiment of the present invention provides an information indication method applied to a network device, the method comprising: a step of the network device changing a service mode; and a step of the network device sending indication information to a terminal device, wherein the indication information indicates an update of a CSI measurement mode, an update of a CSI report, an update of a CSI-RS resource, and / or a switching of a BWP.

[0013] One advantageous effect of the embodiment of the present invention is as follows: the network device changes a service mode and sends indication information to the terminal device, where the indication information indicates updating a CSI measurement mode, updating a CSI report, updating a CSI-RS resource, and / or switching a BWP. This allows the terminal device to unambiguously adapt to the changed service mode through the indication information and accurately determine information such as updating a CSI measurement mode, updating a CSI report, updating a CSI-RS resource, and / or switching a BWP, thereby efficiently transmitting uplink data or receiving downlink data with the network device.

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

[0033] 1 is a schematic diagram of a communication system according to an embodiment of the present invention, and schematically illustrates examples of terminal devices and network devices.

[0036] The current Release 18 (R18) stage introduces the topic of network energy saving. Network energy saving technologies can be classified into time domain, frequency domain, spatial domain, and energy domain types. However, in practical applications, two or more types of energy saving technologies are often combined. For example, spatial domain energy saving technologies can achieve energy saving by adjusting spatial domain elements. Here, spatial domain elements include logical antenna ports, transmitting and receiving units (TXRUs), transmit chains, and array antenna factors. Time domain energy saving technologies can achieve energy saving by cell ON / OFF or reducing common channel / signal transmissions. Frequency domain energy saving technologies can achieve energy saving by bandwidth part (BWP) switching, etc. These energy saving technologies enable network devices to enter energy saving modes (power saving mode or sleep mode). When the network device changes between the normal mode and the energy saving mode, it affects the related processes of the terminal, including updating the channel state information (CSI) measurement mode, updating the channel state information (CSI) report, updating the channel state information reference signal (CSI-RS) resource, switching the bandwidth portion (BWP), etc. The above related processes are the basis for the network device to schedule the terminal device for data reception and data transmission. The above related processes relate to the configuration, instruction, and reporting of the terminal device by the network device.

[0037] Taking the energy saving technology of the spatial domain as an example, at least one change between energy saving mode and normal mode may be made by adjusting the number of spatial domain elements. In the process of achieving energy saving by adjusting the number of spatial domain elements, the terminal device may change the CSI measurement mode. In addition, in principle, the number of spatial domain elements must be equal to or greater 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 domain elements, after the energy saving mode is turned on or off, the number of spatial domain elements may be less than the number of CSI-RS ports, and the CSI-RS time / frequency / spatial domain resources may need to be updated.

[0038] Therefore, how to enable network devices and terminal devices to unambiguously adapt to the effects of different modes is a key issue for determining whether network energy-saving technologies can be applied in actual deployment, and needs to be resolved urgently.In view of at least one of the above problems, embodiments of the present invention provide an information indicating device, an information receiving device, and a method thereof.

[0039] Example 1 The embodiment of the present invention provides an information indicating method, which is explained from the network device side.

[0040] 2 is a schematic diagram of an example of an information indication method according to an embodiment of the present invention. As shown in FIG. 2, the method includes the following steps:

[0041] Step 201: The network device changes the service mode.

[0042] Step 202: The network device sends indication information to the terminal device, where the indication information indicates updating a channel state information (CSI) measurement mode, and / or updating a channel state information (CSI) report, and / or updating a channel state information reference signal (CSI-RS) resource, and / or switching a bandwidth portion (BWP).

[0043] This allows the terminal device to unambiguously adapt to the changed service mode using the instruction information and accurately determine information such as updating the CSI measurement mode, and / or updating the CSI report, and / or updating the CSI-RS resource, and / or switching the BWP, thereby efficiently transmitting subsequent uplink data or receiving downlink data with the network device.

[0044] In some embodiments, the service modes include a normal mode and / or at least one energy saving mode.

[0045] For example, "at least one energy saving mode" may include at least one mode such as "energy saving mode," "light energy saving mode," "deep energy saving mode," or "energy saving transition mode," but the present invention is not limited thereto. The above "normal mode" may be replaced with "normal mode." The above "energy saving mode" may be replaced with expressions such as "power saving mode," "sleep mode," "dormant mode," or "off mode," but the present invention is not limited thereto.

[0046] In some embodiments, the service mode may be changed by changing the "spatial domain elements" or the "antenna mode." For example, the network may be changed from "normal mode" to "energy saving mode" by turning off some of the "spatial domain elements."

[0047] In some embodiments, the "spatial domain element" includes at least one of a logical antenna port, a transmitting and receiving unit (TXRU), a transmit chain, or an array antenna element. In some embodiments, the "spatial domain element" may be directly replaced with "power saving mode." "Determine whether to turn on or off at least some of the spatial domain elements" may be replaced with "determine whether to turn on or off the energy saving mode." Alternatively, "determine whether to turn on or off at least some of the spatial domain elements" may be replaced with "determine whether to activate or deactivate the energy saving mode."

[0048] In some embodiments, time domain energy saving techniques may achieve energy savings through cell ON / OFF or common signaling reduction methods, for example, by switching off some of the cells to change the network from "normal mode" to "energy saving mode."

[0049] In some embodiments, the frequency domain energy saving technique may achieve energy saving by switching bandwidth parts (BWPs), for example, by configuring a specific bandwidth part (BWP) to achieve a "normal mode" or an "energy saving mode."

[0050] In some embodiments, the network device further transmits configuration information to the terminal device, where the configuration information configures a first timer associated with one of the at least one energy saving modes, the first timer setting an operating time for the one of the at least one energy saving modes.

[0051] For example, the network device transmits configuration information through higher layer signaling such as RRC signaling, where the configuration information indicates an operating time of the energy saving mode by a first timer, for example, 300 ms.

[0052] For example, the terminal device reads RRC signaling to obtain the operation time of the energy saving mode. The network device changes the service mode (e.g., switches from the normal mode to the energy saving mode) and sends instruction information to the terminal device. The terminal device updates the CSI measurement mode, and / or updates the CSI report, and / or updates the CSI-RS resource, and / or switches the BWP, and returns to the normal mode after 300 ms. Specific contents indicated by the instruction information will be described later.

[0053] In some embodiments, the network device transmits the indication information via semi-static or dynamic signaling.

[0054] For example, when using RRC signaling to transmit the indication information, for example, when using an RRC reconfiguration flow implemented at the millisecond level, the delay is too large to support the dynamic energy saving mode, and the dynamic energy saving mode may be at the symbol or slot level (less than milliseconds). Also, for example, in normal cases, a user's CSI-RS resources and CSI measurements do not need to be changed frequently, but during energy saving operation, the normal mode and the energy saving mode are frequently switched, and using the RRC signaling flow results in a large overhead and waste of system resources. Therefore, in the above-described embodiments of the present invention, by transmitting the indication information by semi-static signaling or dynamic signaling, the signaling delay and overhead can be further reduced and the dynamic energy saving mode switching can be supported.

[0055] 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 via the DCI. The DCI may be a new DCI format for the energy saving mode, or an existing DCI format may be reused, but the present invention is not limited thereto. 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 an energy saving-RNTI (ES-RNTI), or specific time-frequency resources may be allocated for the new DCI format so that the terminal device can identify the DCI, but the present invention is not limited thereto.

[0056] In some embodiments, this indication information may be transmitted to the terminal device together with signaling indicating a change in service mode. For example, when instructing the terminal device to activate / deactivate an "energy saving mode" via DCI, this indication information may be carried together via DCI. Preferably, this indication information may be transmitted separately from signaling indicating a change in service mode, and the present invention is not limited thereto.

[0057] In some embodiments, the semi-static signaling or dynamic signaling is group signaling, and the network device transmits the indication information to multiple terminal devices via group signaling, or the semi-static signaling or dynamic signaling is user equipment specific (UE) signaling, and the network device transmits the indication information to the terminal device via user equipment specific signaling.

[0058] In some embodiments, the indication information indicates updating of the CSI measurement mode, updating of the CSI report, updating of the CSI-RS resource, and / or switching of the BWP. The following provides a brief description of each of the indications in the above indication information.

[0059] The following describes in detail how to instruct updating of the CSI measurement mode.

[0060] For example, the "CSI measurement mode" means that the terminal device performs "merging processing" or "non-merging processing" on the CSI measurement results. For example, the "merging processing" may be replaced with "merging averaging" or "smooth filtering." Here, specific embodiments of the "merging processing" or "smooth filtering" may refer to the prior art, and the present invention is not limited thereto.

[0061] For example, in "normal mode" ("non-energy saving mode"), the terminal device normally performs a merging process on all CSI measurement results. However, when the "energy saving mode" is on, the transmission power of the channel state indication reference signal (CSI-RS) changes, and the latest CSI measurement mode after switching from the "normal mode" to the "energy saving mode" also changes accordingly, reflecting the channel quality state in real time. For example, when switching from the "normal mode" to the "energy saving mode," if the terminal device still performs a merging process on the CSI measurement results, the CSI measurement results from the "normal mode" and the "energy saving mode" may be merged, and the merged CSI measurement results may not accurately reflect the channel state in the energy saving mode. On the other hand, in an embodiment of the present invention, the instruction information allows the terminal device to timely acquire whether the CSI measurement mode has been changed or not, thereby enabling more accurate CSI measurement.

[0062] In some embodiments, the network device indicates, via the indication information indicating an update of the CSI measurement mode and / or the first timer, whether to change or not change the CSI measurement mode.

[0063] In some embodiments, when the network device changes the service mode, the indication information indicating the update of the CSI measurement mode indicates, via the value of one or more bits, that the CSI measurement mode is to be changed, and / or indicates, via other values ​​of one or more bits, that the CSI measurement mode is not to be changed.

[0064] In some embodiments, if the semi-static signaling or the dynamic signaling is group signaling, the indication information is a bitmap including a number of blocks.

[0065] For example, each block corresponds to one terminal device, and the starting position and / or size of each block is configured by higher layer signaling.

[0066] FIG. 3 is a schematic diagram of an example of instruction information according to an embodiment of the present invention.

[0067] For example, each block represents indication information of one terminal device, and the start position and / or size of each block is given by higher layer parameters. For example, higher layer parameters in an existing standard may be used, or new higher layer parameters may be introduced, and the present invention is not limited thereto.

[0068] For example, if each block is one bit, the network device may use one bit to indicate whether a specific terminal device changes or does not change the CSI measurement mode. For example, if this bit is "1", this CSI measurement mode is changed, i.e., CSI measurement merging processing is not performed. If this bit is "0", this CSI measurement mode is not changed, i.e., CSI measurement merging processing is performed.

[0069] For example, for five terminal devices, the specific content of the instruction information "11010" means that the first, second, and fourth terminal devices will not be subjected to CSI measurement merging processing, and the third and fifth terminal devices will be subjected to CSI measurement merging processing. Taking the third terminal device as an example, it obtains 5 bits of instruction information through higher layer signaling. Here, since the size of each block is 1 bit, the third terminal device may determine the third bit (value "0") as the instruction bit for the third terminal device.

[0070] In some embodiments, if the CSI measurement mode of the terminal device has changed, the indication information carries a block corresponding to the terminal device. If the CSI measurement mode of the terminal device has not changed, the indication information does not carry a block corresponding to the terminal device. For example, if the terminal device does not read a related field of the indication information through higher layer signaling, it determines that the CSI measurement has not changed and continues to use the original CSI measurement mode.

[0071] In some embodiments, when the semi-static signaling or dynamic signaling is terminal-specific signaling, for example, the network device may indicate whether to change or not change the CSI measurement mode with one bit. For example, when this bit is "1," this CSI measurement mode is changed, i.e., CSI measurement merging is not performed. When this bit is "0," this CSI measurement mode is not changed, i.e., CSI measurement merging is performed.

[0072] The above bit contents are merely illustrative and may be set as follows: when the bit is "0", this CSI measurement mode is changed, i.e., CSI measurement merging is not performed, and when this bit is "1", this CSI measurement mode is not changed. The present invention is not limited to this.

[0073] In some embodiments, the terminal device changes the CSI measurement mode after the first timer times out.

[0074] For example, the network device transmits configuration information via higher layer signaling such as RRC signaling, where the configuration information indicates the operation time of the energy saving mode. For example, the terminal device reads the RRC signaling to obtain the operation time of the energy saving mode. The network device changes the service mode (for example, switches from normal mode to energy saving mode) and transmits instruction information to the terminal device (using the instruction method described above). The terminal device updates the CSI measurement mode. For example, when changing from normal mode to energy saving mode, the terminal device does not perform a merging process, and returns to the normal mode after 300 ms has elapsed, and changes the CSI measurement mode. For example, the terminal device does not perform a merging process on the CSI measurements after 300 ms has elapsed.

[0075] This allows the terminal device to obtain specific content of the instruction information and perform more accurate CSI measurements.

[0076] The following describes how to indicate an update to a CSI report.

[0077] In some embodiments, the network device activates / deactivates at least one CSI report via the indication information indicating an update of the CSI report and / or the first timer.

[0078] In some embodiments, when the network device changes the service mode, the indication information indicates activating a first CSI report and / or deactivating a second CSI report, where the first CSI report and / or the second CSI report are configured by higher layer information.

[0079] In some embodiments, the first CSI report and / or the second CSI report belong to a first CSI report list, and the first CSI report list includes a CSI report configuration index (CSI-ReportConfigId), where the first CSI report list and the CSI report configuration index (CSI-ReportConfigId) are configured by higher layer information.

[0080] For example, each CSI report corresponds to a CSI report configuration index (CSI-ReportConfigId), and for example, the CSI report corresponding to CSI report configuration index (CSI-ReportConfigId)=0 is CSI 0.

[0081] For example, the first CSI report list includes which CSI reports are configured by higher layer signaling. For example, the first CSI report list is configured by higher layer signaling to include five CSI reports corresponding to "CSI 0" to "CSI 4," respectively. The terminal device determines which specific CSI reports to activate / deactivate based on the instruction information. Specific examples will be described later in this specification with reference to embodiments.

[0082] In some embodiments, a CSI report configuration index (CSI-ReportConfigId) included in the first CSI report list is associated with a change in at least one of the following information:

[0083] The CSI report periodicity and offset are indicated, for example, by the fields "CSI-ReportPeriodicityAndOffset", "reportSlotConfig", and "reportSlotOffsetList" in higher layer signaling.

[0084] The resources used for the CSI report, for example, are indicated by the field "pucch-CSI-ResourceList" in higher layer signaling.

[0085] The period and offset of the CSI-RS resource associated with the CSI report are indicated, for example, by the field "ResourceConfig" in higher layer signaling.

[0086] The time-frequency resource of the CSI-RS resource associated with the CSI report is indicated, for example, by the field "CSI-ResourceConfig" in higher layer signaling.

[0087] For example, the CSI report in the energy saving mode may have a longer period, e.g., 40 ms for the CSI report in the normal mode and 80 ms for the CSI report in the energy saving mode. For example, the upper layer configures that the periodicity of CSI 0 is 80 ms, the periodicity of CSI 1 is 40 ms, and the first CSI report list includes CSI 0 and CSI 1. After the service mode is changed to the energy saving mode, the indication information may indicate to activate CSI 0 (first CSI report) and deactivate CSI 1 (second CSI report), as will be described later in this specification with reference to embodiments.

[0088] As another example, the CSI-RS resource associated with the CSI report in the energy saving mode is a CSI-RS 16 port, and the CSI-RS resource associated with the CSI report in the normal mode is a CSI-RS 32 port. For example, a higher layer configures that the 32-port CSI-RS 0 is associated with CSI 0, the 16-port CSI-RS 1 is associated with CSI 1, and the first CSI report list includes CSI 0 and CSI 1. After the service mode is changed to the energy saving mode, the instruction information may indicate that CSI 1 (the first CSI report) is activated and CSI 0 (the second CSI report) is deactivated. Activating CSI 1 means activating the 16-port CSI-RS 1 associated with it, and deactivating CSI 0 means activating the 32-port CSI-RS 0 associated with it.

[0089] In some embodiments, for one particular CSI report, the indication information indicates, with one value of one or more bits, that the CSI report is activated, and with another value of the one or more bits, that the CSI report is deactivated.

[0090] 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 corresponding to one terminal device, the starting position and / or size of each block being configured by higher layer signaling, each block including one or more bits, each block indicating a first CSI report list of the terminal device, and each bit in each block corresponding to a CSI report in the first CSI report list.

[0091] For example, still taking the bitmap of multiple blocks shown in Figure 3 as an example, each block represents indication information of one terminal device, and the start position and / or size of each block is given by upper layer parameters. For example, upper layer parameters in an existing standard may be used, or new upper layer parameters may be introduced, but the present invention is not limited thereto.

[0092] For example, each block corresponds to a first CSI report list of one specific terminal device, and each block includes, for example, X bits, where each bit of the X bits corresponds to the activation / deactivation state of one CSI report in the first CSI report list, which may be provided by a higher layer parameter.

[0093] Taking a specific terminal device as an example, the upper layer parameters may configure the first CSI report list to include five CSI reports corresponding to "CSI 0" to "CSI 4," respectively, and indicate the activation / deactivation status of each CSI report with five bits. For example, "0" indicates deactivation of the CSI report, and "1" indicates activation of the CSI report. For example, the upper layer parameters may configure the CSI periodicity of "CSI 0" (first CSI report) to be 80 m and the CSI periodicity of "CSI 1" to "CSI 4" (second CSI report) to be 40 m. The upper layer parameters may transmit "10000," which means that "CSI 0" is activated and "CSI 1" to "CSI 4" are deactivated, to the user equipment.

[0094] For example, in the case of five terminal devices, the indication information is "10000," "10100," "00011," "00100," and "10001." Taking a second terminal device as an example, the indication information acquired by the second terminal device through higher layer signaling is 25 bits in total, starts at the sixth bit, and the size of the terminal indication information is 5 bits, that is, the sixth to tenth bits are indication bits for the second terminal device. Here, "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 merely an exemplary description; for example, the first CSI report list may be different for different terminal devices.

[0095] In some embodiments, if the activation / deactivation state of the CSI report of the terminal device needs to be updated, the indication information carries a block corresponding to the terminal device. If the activation / deactivation state of the CSI report of the terminal device does not need to be updated, the indication information does not carry a block corresponding to the terminal device. For example, if the terminal device does not read a related field of the indication information through higher layer signaling, it determines that the activation / deactivation state of the CSI report does not need to be updated.

[0096] The above bit contents are merely exemplary descriptions, and may be set such that "0" represents activation of the CSI report and "1" represents deactivation of the CSI report, and the present invention is not limited thereto.

[0097] In some embodiments, the first CSI report and / or the second CSI report includes a periodic CSI report, a semi-persistent CSI report, or an aperiodic CSI report. For example, details of the periodic CSI report, the semi-persistent CSI report, or the aperiodic CSI report may refer to the prior art, and the present invention is not limited thereto.

[0098] FIG. 4 is a schematic diagram of an example of a CSI report according to an embodiment of the present invention.

[0099] For example, for a specific terminal device, when the terminal device is in normal mode, the configured CSI is "CSI 0" and the associated CSI-RS resource is "CSI-RS 0". When the terminal device is in energy saving mode, the configured CSI is "CSI 1" and the associated CSI-RS resource is "CSI-RS 1". For example, in addition to the above CSI report update method, when the service mode is changed to energy saving mode, the indication information sent by the network device is "... '01000'...", and the activated CSI corresponding to the update is "CSI 1". For example, when the service mode is changed to normal mode, the indication information sent is "... '10000'...", and the activated CSI corresponding to the update is "CSI 0".

[0100] In some embodiments, when the semi-static signaling or dynamic signaling is terminal device-specific signaling, for example, the network device may indicate a list of first CSI reports using X bits. Each bit of the X bits indicates activation or deactivation of a specific CSI report. For example, "1" indicates activation of a CSI report, and "0" indicates deactivation of a CSI report. For example, the content of each block using the above embodiments is transmitted to a specific terminal device as specific content of terminal device-specific signaling. However, the above embodiments may be referred to for specific indication methods, and description thereof will be omitted here.

[0101] In some embodiments, when the terminal device changes the service mode, the terminal device turns on a first timer and suspends CSI reporting before the service mode change, and after the first timer times out, the terminal device resumes CSI reporting before the service mode change.

[0102] For example, the network device may transmit configuration information via higher layer signaling, such as RRC signaling, where the configuration information indicates an operation time of the energy saving mode. For example, the terminal device may read the RRC signaling and then obtain the operation time of the energy saving mode. The network device may change the service mode (e.g., switch from the normal mode to the energy saving mode) and transmit instruction information (using the above-described instruction method) to the terminal device. The terminal device may then update the activation / deactivation CSI reporting, suspend the activation / deactivation CSI reporting in the normal mode, and return to the normal mode after 300 ms, i.e., after the first timer times out, resume the activation / deactivation CSI reporting in the normal mode.

[0103] This allows the terminal device to obtain the specific content of the instruction information and determine whether to update the CSI report.

[0104] The following provides a specific description of how to instruct updating of CSI-RS resources.

[0105] In some embodiments, the network device activates / deactivates at least one CSI-RS resource according to the indication information indicating an update of the CSI-RS resource and / or the first timer.

[0106] In some embodiments, when the network device changes the service mode, the indication information indicates activating a first CSI-RS resource and / or deactivating a second CSI-RS resource, where the first CSI-RS resource and / or the second CSI-RS resource are configured by higher layer information, and the first CSI-RS resource and / or the second CSI-RS resource are the same or different.

[0107] In some embodiments, the first CSI-RS resource and / or the second CSI-RS resource belong to a first CSI-RS resource set, where the first CSI-RS resource set includes CSI-RS resources and / or CSI-RS ports. An index of the first CSI-RS resource set, as well as the number and indexes of CSI-RS resources and / or the number and / or indexes of CSI-RS ports included in the first CSI-RS resource set, are configured by higher layer information.

[0108] For example, the higher layer signaling may configure a first CSI-RS resource set and its index, a plurality of CSI-RS resources and a plurality of CSI-RS ports included in the first CSI-RS resource set, and a related configuration, where the related configuration of the plurality of CSI-RS resources and the plurality of CSI-RS ports may refer to prior art, and the present invention is not limited thereto.

[0109] The following takes as an example a description that the first CSI-RS resource and / or the second CSI-RS resource belong to a first CSI-RS resource set, and the first CSI-RS resource set includes a CSI-RS resource.

[0110] In some embodiments, for a particular CSI-RS resource, the indication information indicates activation of the CSI-RS resource with one value of one or more bits, and the indication information indicates deactivation of the CSI-RS resource with another value of one or more bits.

[0111] In some embodiments, the CSI-RS resource comprises a set of CSI-RS resources or one CSI-RS resource, and the set of CSI-RS resources is configured by higher layer signaling.

[0112] In some embodiments, when the semi-static or dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks, each corresponding to one terminal device, and the starting position and / or size of each block being configured by higher layer signaling. Each bit corresponds to a set of CSI-RS resources or one CSI-RS resource of the terminal device, and the number of bits is configured by higher layer signaling.

[0113] For example, still taking the bitmap of multiple blocks shown in Figure 3 as an example, each block represents indication information of one terminal device, and the start position and / or size of each block is given by higher layer parameters. For example, higher layer parameters in existing standards may be used, or new higher layer parameters may be introduced, and the present invention is not limited thereto.

[0114] For example, each block corresponds to the activation / deactivation state of each CSI-RS resource in one CSI-RS resource set of one specific terminal device. For example, each block includes X bits, and each bit of the X bits corresponds to the activation / deactivation state of the CSI-RS resource. In some embodiments, the specific configuration of the CSI-RS resource set and the corresponding CSI-RS resource may refer to prior art, and the present invention is not limited thereto.

[0115] For example, the first CSI-RS resource set includes four CSI-RS resources, and the activation / deactivation status of each CSI-RS resource is indicated by four bits, where "0" indicates deactivation of the CSI-RS resource, "1" indicates activation of the CSI-RS resource, and "1010" means that "CSI-RS resource 0" (the first CSI-RS resource set resource) and "CSI-RS resource 2" (the first CSI-RS resource resource) are activated, and "CSI-RS resource 1" (the second CSI-RS resource set resource) and "CSI-RS resource 3" (the second CSI-RS resource resource) are deactivated.

[0116] For example, in the case of two terminal devices, the indication information is "1010" and "0101". Taking the first terminal device as an example, the indication information acquired by higher layer signaling of the first terminal device is 8 bits in total, starting from the first bit and followed by 4 bits. That is, the first to fourth bits are indication bits of the first terminal device. Here, "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.

[0117] Preferably, the indication information may indicate the activation / deactivation status of a set of CSI-RS resources. For example, "CSI-RS resource 0" and "CSI-RS resource 2" belong to Group 0, and "CSI-RS resource 1" and "CSI-RS resource 3" belong to Group 1. For two terminal devices, the indication information is "10" and "01". Taking a first terminal device as an example, the indication information obtained by higher layer signaling of the first terminal device is 4 bits in total. Here, the size of each block is 2 bits, "CSI-RS resource 0" and "CSI-RS resource 2" belong to Group 0, "CSI-RS resource 1" and "CSI-RS resource 3" belong to Group 1, and the first and second bits are indication bits for the first terminal device. Here, "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.

[0118] In some embodiments, if the activation / deactivation status of the CSI-RS resource of the terminal device needs to be updated, the indication information carries a block corresponding to the terminal device. If the activation / deactivation status of the CSI-RS resource of the terminal device does not need to be updated, the indication information does not carry a block corresponding to the terminal device. For example, if the terminal device does not read a related field of the indication information through higher layer signaling, it determines that the activation / deactivation status of the CSI-RS resource does not need to be updated.

[0119] The above bit contents are merely exemplary descriptions, and the present invention is not limited thereto, and may be set such that "0" represents activation of a CSI-RS resource and "1" represents deactivation of a CSI-RS resource.

[0120] FIG. 5 is a schematic diagram of an example of updating a CSI-RS resource according to an embodiment of the present invention.

[0121] As shown in FIG. 5, for example, a 32-port CSI-RS may be supported by a CDM-4 and four resources. Here, one resource of the CDM-4 occupies eight resource elements (REs). The CDM-4 may refer to prior art, and the present invention is not limited thereto. 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 a network device turns off some of the spatial domain elements, the CSI-RS resources of the terminal device are changed from the activation of "Resource 1" to "Resource 4" in FIG. 5 to the activation of "Resource 1" and "Resource 3" and the deactivation of "Resource 2" and "Resource 4." This enables the update from the 32-port CSI-RS resources to the 16-port CSI-RS resources. For example, the above instruction method is adopted, and the overlapping explanation is omitted here.

[0122] In some embodiments, when the semi-static signaling or dynamic signaling is terminal device-specific signaling, for example, the network device may use X bits to indicate the activation / deactivation status of CSI-RS resources included in a CSI-RS resource set. Each bit of the X bits indicates the activation / deactivation status of a specific CSI-RS resource. For example, "1" indicates that the CSI-RS resource is activated, and "0" indicates that the CSI-RS resource is deactivated. Preferably, the network device may use the X bits to indicate the activation / deactivation status of multiple sets of CSI-RS resources included in the CSI-RS resource set. For example, the content of each block using the above embodiments is transmitted to a specific terminal device as specific content of terminal device-specific signaling. For specific indication methods, reference may be made to the above embodiments, and redundant description will be omitted here.

[0123] In some embodiments, the terminal device suspends the CSI-RS resources before the service mode change after the first timer times out, and resumes the CSI-RS resources before the service mode change after the first timer times out.

[0124] For example, the network device may send configuration information through higher layer signaling, such as RRC signaling, where the configuration information indicates an operating time of the energy saving mode. For example, the terminal device may read the RRC signaling and then obtain the operating time of the energy saving mode. The network device may change the service mode (e.g., switch from the normal mode to the energy saving mode) and send instruction information (using the above-mentioned instruction method) to the terminal device. The terminal device may then update the activated / deactivated CSI-RS resources, suspend the activated / deactivated CSI-RS resources in the normal mode, and, after a first timer of 300 ms has expired, return to the normal mode and resume the activated / deactivated CSI-RS resources in the normal mode.

[0125] This allows the terminal device to obtain the specific content of the instruction information and identify the CSI-RS resource that has been activated / deactivated for updating.

[0126] The following takes as an example a case where the first CSI-RS resource and / or the second CSI-RS resource belong to a first CSI-RS resource set, and the first CSI-RS resource set includes a port CSI-RS (CSI-RS port).

[0127] In some embodiments, the indication information indicates activation of the CSI-RS port by one value of one or more bits and indicates deactivation of the CSI-RS port by another value of one or more bits.

[0128] In some embodiments, the CSI-RS port comprises a set of CSI-RS ports or a single CSI-RS port, where the set of CSI-RS ports is configured by higher layer signaling.

[0129] In some embodiments, when the semi-static or dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks, where each block corresponds to one terminal device, and the starting position and / or size of each block is configured by higher layer signaling. Each block includes one or more bits, where each bit corresponds to a set of CSI-RS ports or one CSI-RS port of the terminal device, and the number of bits is configured by higher layer signaling.

[0130] For example, still taking the bitmap of multiple blocks shown in Figure 3 as an example, each block represents indication information of one terminal device, and the start position and / or size of each block is given by higher layer parameters. For example, higher layer parameters in existing standards may be used, or new higher layer parameters may be introduced, and the present invention is not limited thereto.

[0131] For example, each block corresponds to the activation / deactivation state of a CSI-RS port of a specific terminal device, and for example, each block includes, for example, X bits, and each bit of the X bits corresponds to the activation / deactivation state of a CSI-RS port. In some embodiments, the specific configuration of the CSI-RS port may refer to prior art, and the present invention is not limited thereto.

[0132] Preferably, each block may further include related information of a CSI-RS resource, for example, may include a T bit (T may be equal to 0). The T bit indicates a CSI-RS resource set and / or a CSI-RS resource corresponding to a CSI-RS port. Preferably, if T=0, the CSI-RS resource set and / or a CSI-RS resource corresponding to a CSI-RS port is indicated by higher layer information.

[0133] The following will be described by taking T=0, i.e., not indicating a CSI-RS resource set and / or a CSI-RS resource for a CSI-RS port, as an example.

[0134] For example, for 32 CSI-RS ports configurable for a terminal device, the active / inactive status of the CSI-RS ports is indicated by 32 bits, where "0" indicates deactivation of the CSI-RS port and "1" indicates activation of the CSI-RS port. "0000000000000000111111111111111" means activating "CSI-RS Port 16" through "CSI-RS Port 31" and deactivating "CSI-RS Port 0" through "CSI-RS Port 15." Preferably, this indication information may indicate the active / inactive status of a set of CSI-RS ports. This set of CSI-RS ports is one or more CDM groups, for example, "CSI-RS port 0" to "CSI-RS port 15" are group 0, and "CSI-RS port 16" to "CSI-RS port 31" are group 1. Alternatively, the CSI-RS ports are a total of four CDM groups, with "CDM group 0" and "CDM group 1" being group 0, and "CDM group 2" and "CDM group 3" being group 1.

[0135] For example, in the case of two terminal devices, the indication information is "'10', "'01'." Taking the first terminal device as an example, the indication information acquired by the higher layer signaling of the first terminal device is a total of four bits, the starting position corresponding to the terminal device is the first bit, and there are a total of two bits. "CSI-RS Port 0" to "CSI-RS Port 15" are Group 0, "CSI-RS Port 16" to "CSI-RS Port 31" are Group 1, and the first and second bits are indication bits of the first terminal device. Here, "10" indicates that for the first terminal device, "CSI-RS Port 0" to "CSI-RS Port 15" are activated and "CSI-RS Port 16" to "CSI-RS Port 31" are deactivated.

[0136] Furthermore, if T is not equal to 0, it may be indicated by the above-mentioned CSI-RS port activation / deactivation and CSI-RS resource activation / deactivation methods, and the present invention is not limited thereto.

[0137] In some embodiments, if the activation / deactivation status of the CSI-RS port of the terminal device needs to be updated, the indication information carries a block corresponding to the terminal device, and if the CSI-RS port of the terminal device does not need to be updated, the indication information does not carry a 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 determines that the activation / deactivation status of the CSI-RS port does not need to be updated.

[0138] The above bit contents are merely exemplary descriptions, and the present invention is not limited thereto, and may be set such that "0" indicates that the CSI-RS port is activated and "1" indicates that the CSI-RS port is deactivated.

[0139] FIG. 6 is a schematic diagram of an example of updating a CSI-RS port according to an embodiment of the present invention.

[0140] As shown in FIG. 6, for example, a 32-port CSI-RS may be supported by four CDM-8s and one resource. Here, one resource of the CDM-8 occupies 32 resource elements (REs). The CDM-8 may refer to prior art, and the present invention is not limited thereto. 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 a network device turns off some of the spatial domain elements, the CSI-RS resource of the terminal device can be updated from 32-port CSI-RS to 16-port CSI-RS by changing the CSI-RS resource from "activating CSI-RS ports 0 to 31" in FIG. 6 to "activating CSI-RS ports 0 to 15." For example, the above-mentioned indication method can be used. Here, redundant explanations will be omitted.

[0141] 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 state of a CSI-RS port using X bits. Each bit of the X bits indicates the activation / deactivation state of a specific CSI-RS port, for example, "1" indicates that the CSI-RS port is activated and "0" indicates that the CSI-RS resource is deactivated. Preferably, the network device may indicate the activation / deactivation state of multiple sets of CSI-RS ports using X bits. For example, the content of each block employed in the above embodiments is transmitted to a specific terminal device as specific content of terminal device-specific signaling. However, the above embodiments may be referred to for specific indication methods, and redundant description will be omitted here.

[0142] In some embodiments, the terminal device suspends the CSI-RS port before the service mode change after the first timer times out, and resumes the CSI-RS port before the service mode change after the first timer times out.

[0143] For example, the network device transmits configuration information through higher layer signaling, such as RRC signaling, where the configuration information indicates the operation time of the energy saving mode. For example, the terminal device obtains the operation time of the energy saving mode after reading the RRC signaling, the network device changes the service mode (for example, switches from the normal mode to the energy saving mode), and sends instruction information (using the above instruction method) to the terminal device, so that the terminal device activates / deactivates the CSI-RS port and suspends the CSI-RS port for activation / deactivation in the normal mode, and then returns to the normal mode after 300 ms of the first timer timeout and resumes the CSI-RS port for activation / deactivation in the normal mode.

[0144] This allows the terminal device to obtain the specific content of the instruction information and identify the updated activated / deactivated CSI-RS port (CSI-RS port).

[0145] The following explains in detail how to instruct BWP switching.

[0146] In some embodiments, the network device indicates the BWP after the service mode change by using the indication information indicating the BWP switch and / or the first timer.

[0147] In some embodiments, when the network device changes the service mode, the indication information indicates a BWP index after the service mode change, where the BWP index is configured by upper layer information.

[0148] In some embodiments, the BWP index is associated with a CSI report configuration index (CSI-ReportConfigId), where the CSI report configuration index (CSI-ReportConfigId) associated with the BWP index is configured by higher layer information.

[0149] In some embodiments, when a network device changes a service mode, it switches to activate a BWP corresponding to a BWP index after the service mode change, activates a CSI report associated with an associated CSI report configuration index (CSI-ReportConfigId), and deactivates a CSI report associated with a CSI report configuration index (CSI-ReportConfigId) associated with a BWP index before the service mode change.

[0150] In some embodiments, when the semi-static or dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks, where each block corresponds to one terminal device, and the starting position and / or size of each block is configured by higher layer signaling, and each block includes one or more bits indicating the index of the BWP to which the terminal device should switch.

[0151] For example, still taking the bitmap of multiple blocks shown in Figure 3 as an example, each block represents indication information of one terminal device, and the start position and / or size of each block is given by higher layer parameters. For example, higher layer parameters in existing standards may be used, or new higher layer parameters may be introduced, and the present invention is not limited thereto.

[0152] For example, when each block corresponds to turning on or off at least some of the spatial domain elements, for example, each block includes X bits corresponding to the index of one BWP for the index of the BWP that the terminal device is about to switch. In some embodiments, the setting of the BWP and its index may refer to the prior art, and the present invention is not limited thereto.

[0153] For example, one terminal device is configured with four BWPs, and the indication information is 2 bits long and indicates the BWP index to be switched to. For example, "00" indicates switching to BWP 0, "01" indicates switching to BWP 1, "10" indicates switching to BWP 2, and "11" indicates switching to BWP 3. For example, if 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, the indication information may be "00", which indicates that CSI reporting in the normal mode of the terminal device is deactivated corresponding to activating CSI 0, and that CSI 1 in the normal mode configured by the higher layer signaling is deactivated.

[0154] For example, for two terminal devices, when changing the service mode, the instruction information is "10" and "01". Taking the first terminal device as an example, the instruction information obtained by the upper layer signaling of the first terminal device is 4 bits in total, the size of each block is 2 bits, and the first and second bits are the instruction bits of the first terminal device. For example, "10" indicates that the first terminal device should be switched to BWP 2.

[0155] In some embodiments, if the BWP of the terminal device needs to be switched, the indication information carries a block corresponding to the terminal device, and if the BWP of the terminal device does not need to be switched, the indication information does not carry a block corresponding to the terminal device. For example, if the terminal device does not read a related field of the indication information through upper layer signaling, it determines that the BWP of the terminal device does not need to be switched.

[0156] In some embodiments, the terminal device suspends the BWP index before the service mode change, and resumes the BWP index before the service mode change after the first timer times out.

[0157] For example, the network device sends configuration information through higher layer signaling, such as RRC signaling, where the configuration information indicates the operation time of the energy saving mode. For example, the terminal device reads the RRC signaling to obtain the active time of the energy saving mode, the network device changes the service mode (for example, switches from the normal mode to the energy saving mode), and sends instruction information to the terminal device (using the above instruction method), so that the terminal device updates the switched BWP index and suspends the BWP index of the normal mode, and returns to the normal mode after the timeout of the first timer of 300 ms, and switches back to the BWP index of the normal mode.

[0158] This allows the terminal device to obtain the specific content of the instruction information and identify the switched BWP index.
