Technical Field

[0002] The present disclosure relates to the field of wireless communication technologies, and in particular, to a communication method, apparatus and storage medium. Background Art

[0003] In a wireless communication system, the channel environment for data transmission is affected by various factors. Among them, in a wireless communication system, the channel quality condition of the physical downlink channel can be obtained in real time through CSI reference signals.

[0046] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0047] In a wireless communication system, a terminal and a network-side device need to communicate through a transmission channel, and the transmission channel is easily affected by various factors, resulting in the transmission channel in the communication system showing dynamic change characteristics. In the related art, the channel quality condition of the physical downlink control channel can be obtained in real time through a Channel State Information-Reference Signal (CSI-RS). Among them, the implementation method includes: the network-side device sends CSI-RS to the terminal through configuration information. The terminal measures the received CSI-RS and reports the channel state information measurement result to the network-side device. The network-side device determines the channel quality condition of the physical downlink control channel according to the channel state measurement result reported by the terminal and performs relevant scheduling processing.

[0048] In the related wireless communication system, there are three ways for the terminal to report channel state measurement information.

[0049] In one way, the terminal reports channel state measurement information based on a period. Specifically, the network-side device configures the time-frequency domain resources for the terminal to report channel state measurement information periodically through Radio Resource Control (RRC) signaling. The terminal performs periodic measurement of the channel state information and reports the channel state measurement information periodically according to the measurement period of the channel state information, and this method carries the channel state measurement information through a physical uplink control channel (PUCCH).

[0050] In another way, the terminal reports channel state measurement information in a semi-persistent manner. In this way, the resources used to report channel state measurement information can be PUCCH resources or physical uplink shared channel (PUSCH) resources. Among them, when the terminal reports channel state measurement information based on PUSCH resources, it includes: the terminal obtains the resources for reporting channel state measurement information based on dynamic signaling from the network side. And when the terminal semi-persistently reports channel state measurement information based on PUSCH resources, it can be activated or deactivated by the downlink control signaling (DCI) scrambled by the scheduling request (SR) channel state information radio network temporary identity (RNTI) SP-CSI-RNTI for the terminal to use PUSCH resources to report channel state measurement information. When the terminal reports channel state measurement information based on PUCCH resources, it includes: the network side device can configure semi-static reporting resources for the terminal through RRC signaling. Also, when the terminal semi-persistently reports channel state measurement information using PUCCH resources, it is activated or deactivated by the media access control layer control element (MAC-CE) on the PUCCH resources for the terminal to use PUCCH resources to semi-persistently report channel state measurement information. Exemplarily, if the time slot for the terminal to receive the hybrid automatic repeat request (HARQ) acknowledgement (ACK) corresponding to the physical downlink shared channel (PDSCH) is n, then the CSI reported by the terminal becomes effective starting from the n + 3N slot subframe，u +1 time slot.

[0051] In yet another way, the terminal reports channel state measurement information in an aperiodic manner. In this way, the terminal is triggered to report channel state measurement information by DCI scrambled by C-RNTI and reports based on PUSCH resources. At this time, the network side device indicates the channel state measurement information reported by the terminal through the CSI Request field in format 0_1 of the DCI.

[0052] For the three usage scenarios of low-capability terminal Redcap UE, such as factory sensors, video surveillance, and wearable devices. Among them, the deployment locations of factory sensors and video surveillance devices are relatively fixed. Therefore, the channel state changes of the terminals where factory sensors and video surveillance devices are deployed are also relatively small. However, if the above three methods are still used to report channel state measurement information in a wireless system, it is easy to cause unnecessary energy consumption and / or resource overhead for channel state information reporting.

[0053] Based on the problems involved in the above embodiments, the present disclosure provides a method for reporting channel state information. Figure 1 It is a communication system architecture diagram of a network device and a terminal shown according to an exemplary embodiment. The method for reporting channel state information provided by the present disclosure can be applied to Figure 1 the communication system architecture diagram shown, as Figure 1 shown, the terminal measures the channel state information based on the CSI-RS sent by the network side device to obtain the channel state measurement information. Compare this channel state measurement information with the previous channel state information measurement. If the channel state measured this time has a relatively large change compared with the channel state measured last time, then report this channel state measurement information to the network side device. Otherwise, the terminal does not report the channel state measurement information. Further saving the reporting energy consumption and / or resource overhead used for reporting channel state measurement information.

[0054] It can be understood that Figure 1 the communication system of the network device and the terminal shown is only for illustrative purposes. The wireless communication system may also include other network devices, such as core network devices, wireless relay devices, and wireless backhaul devices, etc., which are not drawn in Figure 1 this figure. The present disclosure embodiments do not limit the number of network devices and terminals included in this wireless communication system.

[0055] It can be further understood that the wireless communication system of the embodiments of the present disclosure is a network that provides wireless communication functions. The wireless communication system can adopt different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single Carrier FDMA (SC-FDMA), Carrier Sense Multiple Access with Collision Avoidance. According to factors such as the capacity, rate, and latency of different networks, the network can be divided into 2G (generation) networks, 3G networks, 4G networks, or future evolved networks, such as 5G networks. 5G networks can also be referred to as New Radio (NR). For the convenience of description, the wireless communication network is sometimes simply referred to as the network in the present disclosure.

[0056] Furthermore, the network device involved in the present disclosure can also be referred to as a radio access network device. The radio access network device can be: a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc. It can also be a gNB in the NR system, or it can also be a component or part of the device that constitutes the base station. When it is a vehicle-to-everything (V2X) communication system, the network device can also be a vehicle-mounted device. It should be understood that in the embodiments of the present disclosure, the specific technologies and specific device forms adopted by the network device are not limited.

[0057] Further, the terminal involved in the present disclosure may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. It is a device that provides voice and / or data connectivity to users. For example, the terminal may be a handheld device with wireless connection function, a vehicle-mounted device, etc. Currently, some examples of terminals are: smart phones (Mobile Phone), pocket personal computers (PPC), palm computers, personal digital assistants (PDA), laptop computers, tablet computers, wearable devices, or vehicle-mounted devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the specific technologies and specific device forms adopted by the terminal in the embodiments of the present disclosure are not limited.

[0058] In the embodiments of the present disclosure, a method for reporting channel state information is provided. The following embodiments will illustrate the method for reporting channel state information in conjunction with the accompanying drawings.

[0059] Figure 2 is a flowchart of a method for reporting channel state information shown according to an exemplary embodiment, as Figure 2 shown, the method for reporting channel state information is used in a terminal and includes the following steps.

[0060] In step S11, a first configuration parameter is determined.

[0061] In the embodiments of the present disclosure, the first configuration parameter is used to indicate the parameters for a first type of terminal to report channel state measurement information. The first configuration parameter may include a threshold value, where the threshold value includes, for example, the threshold value for reporting channel state measurement information. In some other embodiments, in addition to the threshold value, the first configuration parameter may further include any one of the following parameters: the number of measurement reports; the measurement object; the acquisition method of the reporting resource for reporting channel state measurement information.

[0062] Exemplarily, the first type of terminal may be a low-capability terminal redcap UE or a stationary redcap UE. Of course, the terminal is only an example and not a specific limitation of the present disclosure.

[0063] In some embodiments, the first configuration parameter includes at least a threshold value.

[0064] In some other embodiments, the first configuration parameter may further include the number of measurement reports; in other words, it configures the number of measurement items that the terminal needs to report.

[0065] In still other embodiments, the first configuration parameter may further include a measurement object (e.g., a physical resource for downlink measurement).

[0066] In some embodiments, the first configuration parameter may further include a manner of obtaining a reporting resource for the terminal to report channel state measurement information. It can be understood that the network-side device may configure multiple different manners of obtaining reporting resources for the terminal.

[0067] Moreover, the network-side device configures the first parameter for the terminal to report channel state information through high-layer RRC signaling. And according to the terminal characteristics of the first type, the network-side device configures the first configuration parameter for the terminal through RRC signaling in a relatively fixed periodic configuration manner.

[0068] In step S12, measurement information is reported based on a threshold value.

[0069] In the embodiments of the present disclosure, the terminal determines whether to report the current measurement information based on the threshold value configured by the network-side device.

[0070] In the embodiments of the present disclosure, the measurement information may include channel state measurement information, and the channel state measurement information is, for example, Signal to Interference plus Noise Ratio (SINR). Hereinafter, taking the channel state measurement information of the current channel state as the first channel state information measurement value M(n), the channel state measurement information of the previous channel state as the second channel state information measurement value M(n - 1), and the threshold value as M_delta as an example for illustration. Through the method for reporting channel state measurement information of the present disclosure, the resource overhead for reporting channel state measurement information can be effectively reduced.

[0071] In an implementation manner of the present disclosure, if the difference between the first channel state information measurement value and the second channel state information measurement value is greater than the threshold value, the terminal reports the channel state measurement information. In some embodiments, the threshold value may be the absolute value of the difference between the first channel state information measurement value and the second channel state information measurement value, that is, |M(n) - M(n - 1)| > M_delta, then the terminal reports the channel state measurement information. Or, if the difference between the first channel state information measurement value and the second channel state information measurement value is equal to the threshold value, the terminal reports the channel state measurement information. In some embodiments, the threshold value may be the absolute value of the difference between the first channel state information measurement value and the second channel state information measurement value, that is, |M(n) - M(n - 1)| = M_delta, then the terminal reports the channel state measurement information.

[0072] In all embodiments of the present disclosure, the threshold value may be the difference between the first channel state information measurement value and the second channel state information measurement value, or may be the absolute value of the difference between the first channel state information measurement value and the second channel state information measurement value; in any one of the embodiments of the present disclosure, it will not be elaborated herein.

[0073] In an embodiment of the present disclosure, if the difference between the first channel state information measurement value and the second channel state information measurement value is less than the threshold value (including, for example, the channel state measurement information reporting threshold value), the terminal reports the channel state information measurement information. In some embodiments, the threshold value may be the absolute value of the difference between the first channel state information measurement value and the second channel state information measurement value, that is, |M(n) - M(n - 1)| < M_delta, then the terminal reports the channel state measurement information. Alternatively, if the difference between the first channel state information measurement value and the second channel state information measurement value is equal to the threshold value, the terminal reports the channel state measurement information. In some embodiments, the threshold value may be the absolute value of the difference between the first channel state information measurement value and the second channel state information measurement value, that is, |M(n) - M(n - 1)| = M_delta, then the terminal reports the channel state measurement information.

[0074] In an embodiment of the present disclosure, the network side device may configure at least one threshold value for the terminal. The threshold value may be configured according to the type of the terminal or different service types included in the terminal. Exemplarily, if a type of terminal is sensitive to the channel quality condition, for example, a stationary security class sensor, a relatively small threshold value is configured for this type of sensor. If the terminal is an ordinary video surveillance device, a relatively large threshold value is configured for this terminal. That is, different service types may correspond to different threshold values; or, different terminal types may correspond to different threshold values; or, different services in the same terminal have different requirements for the channel quality condition, and multiple threshold values are configured for the terminal according to different service requirements.

[0075] In an embodiment of the present disclosure, when the terminal triggers the reporting of the channel state measurement information, the channel state measurement information may be reported through different resources. In some embodiments, the terminal may actively perform the reporting of the channel state measurement information; in some embodiments, the terminal may perform the reporting of the channel state measurement information according to the provisions of relevant communication protocols; in some embodiments, the terminal may perform the reporting of the channel state measurement information according to a preset trigger time.

[0076] An embodiment of the present disclosure proposes a method for reporting channel state information. This embodiment may be implemented alone or may be implemented together with any other embodiment of the present disclosure. The method for reporting channel state information in the embodiment of the present disclosure includes: the terminal reports the channel state measurement information through PUCCH resources.

[0077] In one implementation, for the case where the terminal periodically measures the channel state information based on the first period, the network-side device configures the PUCCH resource for the terminal to periodically report the channel state measurement information. The terminal periodically reports the channel state measurement information based on the second period on the physical uplink control channel PUCCH resource. Wherein, the second period has the same time-domain resource start position and slot length as the first period, and the time-domain position of the PUCCH resource in the second period is offset by N slots relative to the time-domain resource position in the first period, serving as the time-domain resource position for transmitting the current channel state measurement information. And in the embodiments of the present disclosure, the offset N slots need to be determined based on factors such as the time for comparing the channel state measurement information, the start time of the uplink symbol, and the alignment time of the slot. And it is also possible to appropriately expand the first period and the second period according to the stable channel quality condition of the terminal. For example, increase the first period and the second period to 1280 time slots, etc., which can effectively reduce the power consumption of the terminal. In the embodiments of the present disclosure, when the terminal periodically reports the CSI measurement information based on the second period on the physical uplink control channel PUCCH resource, it reports the channel state measurement information using the format 2 of the PUCCH resource. Reporting the channel state measurement information using the format 2 of the PUCCH resource is applicable to the channel state measurement information with a smaller payload, avoiding the waste of the PUCCH resource.

[0078] In another implementation, for the case where the terminal performs aperiodic measurement of the channel state information. The network-side device statically configures the time-frequency domain resources of the PUCCH for the terminal to report the channel state information through RRC signaling. The channel state measurement information is reported based on the first PUCCH resource. The time-domain position of the first PUCCH is: offset by N time slots relative to the time-domain resource position corresponding to the channel state information measurement, serving as the time-domain resource position for transmitting the current channel state measurement information. This implementation is similar to the above implementation. To avoid wasting the PUCCH resource, the channel state measurement information is reported using the format 2 of the PUCCH resource. Reporting the channel state measurement information using the format 2 of the PUCCH resource is applicable to the channel state measurement information with a smaller payload.

[0079] Exemplarily, Figure 3 is a schematic diagram of the offset time slots between the reported channel state measurement information and the time-domain resource position of the channel state information measurement in a channel state information reporting method shown according to an exemplary embodiment. As Figure 3 shown, if the value of N is 2, the time-domain resource position of the reported channel state measurement information is offset by 2 time slots from the time-domain resource position of the channel state information measurement.

[0080] The terminal reports channel state measurement information based on the second period, which enables the terminal to report channel state measurement information in a timely manner. When the channel quality state changes little, the terminal does not need to report channel state measurement information, which can effectively reduce the radio frequency energy consumption overhead of channel state information reporting.

[0081] In the embodiments of the present disclosure, the offset positions of N time slot resources can be determined based on predefined information. In some embodiments, N can be set to a fixed value through signaling or communication protocols configured by the base station; in other embodiments, the offset value N can be dynamically determined based on signaling configured by the base station. The terminal determines the value of N based on the predefined information and reports channel state measurement information with an offset of N time slots relative to the time domain resource position of the channel state information measurement. In another way, the value of N can also be determined through RRC signaling. At this time, the value of N can vary flexibly. The network-side device can select a candidate offset time slot from the offset time slot set as the time domain resource position for reporting channel state measurement information with an offset of N time slots relative to the channel state information measurement based on the processing capability of the terminal, and configure the value of N for the terminal through RRC signaling. As described above, channel state information measurement and reporting of channel state measurement information are performed based on different time domain resources of PUCCH resources, without complex scheduling processes.

[0082] Reporting channel state information measurement information based on PUCCH resources also includes a method. The terminal can request to obtain the PUCCH resources for reporting channel state measurement information through the first uplink scheduling request (Scheduling Request, SR) SR1.

[0083] In some embodiments, the first uplink scheduling request SR1 is dedicated to requesting resources for reporting CSI measurement information.

[0084] When the network-side device receives the dedicated SR1 signaling sent by the terminal, it allocates the PUCCH resources required for the terminal to report channel state measurement information. According to the above embodiments, the first configuration parameter for the terminal to report channel state information is determined by the network side. Therefore, the network-side device can determine the size of the payload for the terminal to report channel state measurement information at this time. When the network-side device determines that the payload for the terminal to report channel state measurement information is small at this time, the network-side device can instruct the terminal to use PUCCH format 2 to report channel state measurement information. When the network-side device determines that the payload for the terminal to report channel state measurement information is large at this time, the network-side device can instruct the terminal to use a new PUCCH format to report channel state measurement information, and allocate more time-frequency resources for the new PUCCH format. The network-side device instructs the terminal to use the PUCCH resource position and format through DCI instructions.

[0085] An embodiment of the present disclosure provides a method for reporting channel state information. This embodiment can be implemented independently or in combination with any other embodiment of the present disclosure. The method for reporting channel state information in the embodiment of the present disclosure includes: a terminal reporting channel state measurement information through PUSCH resources.

[0086] In one implementation, for the case where there are available PUSCH resources for the terminal currently. If the terminal determines that there are available PUSCH resources currently, it determines to use the currently available PUSCH resources to report channel state measurement information. For the convenience of description in the present disclosure, the currently available PUSCH resources are referred to as the first PUSCH resources. Among them, the first PUSCH resources are used to transmit other uplink data simultaneously. In the embodiment of the present disclosure, to distinguish the channel state measurement information from other uplink data, the MAC CE of the first PUSCH resources is used to carry the channel state measurement information. The MAC CE uses the reserved value 35 of the logical channel identify (LCID) of the Uplink Shared Channel (UL-SCH). In the embodiment of the present disclosure, the MAC CE for reporting the channel state measurement information is a variable byte, and the number of bytes of the MAC CE for reporting the channel state measurement information is determined based on the number of measurement items included in the reported channel state measurement information.

[0087] In another implementation, the terminal can reuse the PUSCH resources carrying the Buffer Status Report (BSR) to report channel state measurement information. Exemplarily, this implementation can be applied to the case where there are no available PUSCH resources currently and no other available uplink transmissions. For the convenience of description in the present disclosure, the PUSCH resources carrying the BSR are referred to as the second PUSCH resources. In the present disclosure, the reserved value 35 of the LCID of the UL-SCH is used for reporting the channel state measurement information. Exemplarily, Figure 4 FIG. is a schematic diagram of reusing the PUSCH resources carrying the BSR to report channel state measurement information according to an exemplary embodiment of a method for reporting channel state information. As Figure 4 shown, the terminal requests the network-side device to configure PUSCH resources for reporting channel state measurement information based on a general Scheduling Request (SR). After receiving the request information sent by the terminal, the network-side device configures PUSCH resources for the terminal, and the terminal reports channel state measurement information according to the PUSCH resources configured by the network-side device. It can be understood that since the PUSCH resources allocated by the network-side device for the terminal to transmit the BSR are relatively small. Therefore, this implementation is applicable to the case where the payload for carrying the channel state measurement information is relatively small.

[0088] In another embodiment, the channel state measurement information is reported by using a first PUSCH resource for transmitting other uplink data transmissions to upload the channel state measurement information to the network device; or, the channel state measurement information is uploaded to the network device together with other uplink transmission data. Exemplarily, this embodiment can be applied to a situation where there is no available PUSCH resource currently and there is other uplink transmission. Figure 5 FIG. is a schematic diagram of reporting channel state measurement information by using other uplink data transmission resources in a channel state information reporting method shown according to an exemplary embodiment. As Figure 5 shown, at this time, the terminal applies for using a PUSCH resource for reporting channel state measurement information based on a general scheduling request SR. Taking other uplink data as a BSR as an example, the base station configures a PUSCH resource for transmitting the BSR for the terminal based on the scheduling request sent by the terminal. The BSR transmitted by the terminal reports the signaling of the channel state measurement information and the overhead of other data to the network device together. The network device configures a PUSCH resource for uploading other data and channel state measurement information for the terminal based on the signaling of the channel state measurement information and the overhead of other data. The terminal reports the channel state measurement information and other uplink data based on the PUSCH resource. In the embodiment of the present disclosure, the reporting of the channel state measurement information is carried by a MAC-CE of the PUSCH resource, and the reserved value 35 of the LCID using the UL-SCH is used. This embodiment can also be used in a situation where the payload of the channel state measurement information is large and there is no other uplink data to be transmitted.

[0089] In the embodiment of the present disclosure, reporting the channel state measurement information based on the PUSCH resource further includes a method. The terminal can send a second uplink scheduling request SR2, and the second uplink scheduling request SR2 is dedicated to requesting to obtain a third PUSCH resource for reporting the channel state measurement information, and the third PUSCH resource is dedicated to transmitting the channel state measurement information. The implementation method includes that the terminal sends an SR2 request to apply for a third PUSCH resource for reporting the channel state measurement information, and the network side allocates a third PUSCH resource for reporting CSI measurement information for the terminal based on the dedicated scheduling request SR2 of the terminal. The size of the third PUSCH resource is determined based on a first configuration parameter configured by the network device for the terminal.

[0090] In the embodiment of the present disclosure, by configuring multiple ways of reporting the channel state measurement information, the flexibility of reporting the channel state measurement information is increased. Moreover, the dedicated SR1 and SR2 involved in the present disclosure are redesigned, and the general SR and the dedicated SR1 and SR2 can be distinguished by different time-frequency domain resource positions / sequences. It can be understood that the redesigned dedicated SR1 and SR2 in the present disclosure will not affect other uplink scheduling requests.

[0091] An embodiment of the present disclosure provides a method for reporting channel state information. This embodiment can be implemented independently or in combination with any other embodiment of the present disclosure. The method for reporting channel state information in the embodiment of the present disclosure includes: a terminal cooperatively reports channel state measurement information through PUCCH resources and PUSCH resources.

[0092] In some embodiments, when there are available PUCCH resources, the PUCCH resources are used to report channel state measurement information; when there are no available PUCCH resources, the PUSCH resources are used to report channel state measurement information. As for how to report through PUCCH resources, any method in the embodiments of the present disclosure can be referred to, or any feasible method in related technologies can be adopted. Similarly, as for how to report through PUSCH resources, any method in the embodiments of the present disclosure can be referred to, or any feasible method in related technologies can be adopted.

[0093] In some embodiments, it can be that when there are available PUCCH resources, the PUCCH resources are used to report channel state measurement information; when there are no available PUCCH resources, the PUSCH resources are used to report channel state measurement information. As for how to report through PUCCH resources, any method in the embodiments of the present disclosure can be referred to, or any feasible method in related technologies can be adopted. Similarly, as for how to report through PUSCH resources, any method in the embodiments of the present disclosure can be referred to, or any feasible method in related technologies can be adopted.

[0094] Based on the same or similar concept, an embodiment of the present disclosure further provides a method for reporting channel state information.

[0095] Figure 6 is a flowchart of a method for reporting channel state information shown according to an exemplary embodiment. As Figure 6 shown, the method for reporting channel state information is used in a network device and includes the following steps.

[0096] In step S21, a first configuration parameter is determined.

[0097] In the embodiment of the present disclosure, the first configuration parameter is used to indicate the parameters for a first type of terminal to report channel state measurement information, and the first configuration parameter may include a threshold value. In some other embodiments, in addition to the threshold value, the first configuration parameter may further include any one of the following parameters: the number of measurement reports; the measurement object; the acquisition method of the reporting resource for reporting channel state measurement information.

[0098] Exemplarily, the first type of terminal may be a low-capability terminal redcap UE or a stationary redcap UE. Of course, the terminal is only an example and not a specific limitation of the present disclosure.

[0099] In some embodiments, the network-side device determines a first configuration parameter, which is used to indicate the parameters for the first type of terminal to report channel state measurement information. The first configuration parameter at least includes a threshold value; receives the measurement information of the channel state, and the measurement information of the channel state is reported by the first type of terminal based on the magnitude relationship between the threshold value and the difference value; wherein, the first type of terminal is a low-capability terminal, and the measurement information of the channel state is the measurement information of the channel state reported by the first type of terminal based on the magnitude relationship between the threshold value and the difference value.

[0100] In some embodiments, the first configuration parameter at least includes a threshold value.

[0101] In some other embodiments, the first configuration parameter may further include the number of measurement reports; in other words, it configures the number of measurement items that the terminal needs to report.

[0102] In still some other embodiments, the first configuration parameter may further include a measurement object (for example, the physical resources for downlink measurement).

[0103] In some embodiments, the first configuration parameter may further include the acquisition method of the reporting resource for the terminal to report the channel state measurement information. It can be understood that the network-side device may configure multiple different acquisition methods of the reporting resources for the terminal.

[0104] Moreover, the network-side device configures the first parameter for the terminal to report the channel state information through high-layer RRC signaling. And according to the characteristics of the first type of terminal, the network-side device configures the first configuration parameter for the terminal in a relatively fixed periodic configuration manner through RRC signaling. In the embodiments of the present disclosure, the network-side device receives the channel state measurement information reported by the terminal. The channel state measurement information is the channel state measurement information reported by the first type of terminal in response to the difference between the first channel state information measurement value and the second channel state information measurement value of the channel state being greater than the threshold value. Or the channel state measurement information is the channel state measurement information reported by the first type of terminal in response to the difference between the first channel state information measurement value and the second channel state information measurement value of the channel state being equal to the threshold value.

[0105] In an embodiment of the present disclosure, the terminal determines whether to report the channel state measurement information of this time based on the threshold value configured by the network-side device. In an embodiment of the present disclosure, the channel state measurement information may be the Signal to Interference plus Noise Ratio (SINR). Hereinafter, taking the channel state measurement information of this channel state as the first channel state information measurement value M(n), the CSI measurement information of the previous channel state as the second channel state information measurement value M(n - 1), and the CSI measurement information reporting threshold value as M_delta as an example for illustration. By the method for reporting channel state measurement information in the present disclosure, the resource overhead for reporting channel state measurement information can be effectively reduced.

[0106] In an embodiment of the present disclosure, if the difference between the first channel state information measurement value and the second channel state information measurement value is greater than the threshold value, the terminal reports the channel state measurement information. In some embodiments, the threshold value may be the absolute value of the difference between the first channel state information measurement value and the second channel state information measurement value, that is, |M(n) - M(n - 1)| > M_delta, then the terminal reports the channel state information measurement information. Or, if the difference between the first channel state information measurement value and the second channel state information measurement value is equal to the threshold value, the terminal reports the channel state measurement information. In some embodiments, the threshold value may be the absolute value of the difference between the first channel state information measurement value and the second channel state information measurement value, that is, |M(n) - M(n - 1)| = M_delta, then the terminal reports the channel state measurement information.

[0107] In all embodiments of the present disclosure, the threshold value may be the difference between the first channel state information measurement value and the second channel state information measurement value, or may be the absolute value of the difference between the first channel state information measurement value and the second channel state information measurement value; in any one embodiment of the present disclosure, it will not be elaborated.

[0108] In an embodiment of the present disclosure, if the difference between the first channel state information measurement value and the second channel state information measurement value is less than the threshold value, the terminal reports the channel state information measurement information. In some embodiments, the threshold value may be the absolute value of the difference between the first channel state information measurement value and the second channel state information measurement value, that is, |M(n) - M(n - 1)| < M_delta, then the terminal reports the channel state measurement information. Or, if the difference between the first channel state information measurement value and the second channel state information measurement value is equal to the threshold value, the terminal reports the channel state information measurement information. In some embodiments, the threshold value may be the absolute value of the difference between the first channel state information measurement value and the second channel state information measurement value, that is, |M(n) - M(n - 1)| = M_delta, then the terminal reports the channel state measurement information.

[0109] In the embodiments of the present disclosure, the network-side device may configure at least one threshold value for the terminal. The threshold value may be configured according to the type of the terminal or different service types included in the terminal. Exemplarily, if a type of terminal is sensitive to the channel quality condition, for example, a stationary security sensor, a relatively small threshold value is configured for this type of sensor. If the terminal is an ordinary video surveillance device, a relatively large threshold value is configured for this terminal. That is, different service types may correspond to different threshold values; or different terminal types may correspond to different threshold values; or different services in the same terminal have different requirements for the channel quality condition, and multiple threshold values are configured for the terminal according to different service requirements.

[0110] In the embodiments of the present disclosure, when the terminal triggers the reporting of channel state measurement information, the channel state measurement information may be reported through different resources. In some embodiments, the terminal may actively perform the reporting of channel state measurement information; in some embodiments, the terminal may perform the reporting of channel state measurement information according to the relevant communication protocol regulations; in some embodiments, the terminal may perform the reporting of channel state measurement information according to a preset trigger time.

[0111] The embodiments of the present disclosure propose a method for reporting channel state information. This embodiment may be implemented independently or may be implemented together with any other embodiment of the present disclosure. The method for reporting channel state information in the embodiments of the present disclosure includes: the network-side device receives channel state measurement information through PUCCH resources.

[0112] In some embodiments, measurement is performed based on an extended measurement period, and the extended measurement period is the period for determining the channel state measurement value.

[0113] In one implementation, for the case where the terminal periodically measures the channel state information based on the first period, the network-side device configures the PUCCH resource for the terminal to periodically report the channel state measurement information. The terminal periodically reports the channel state measurement information based on the second period on the physical uplink control channel PUCCH resource. Wherein, the second period has the same time-domain resource start position and slot length as the first period, and the time-domain position of the PUCCH resource in the second period is offset by N slots relative to the time-domain resource position in the first period, serving as the time-domain resource position for transmitting the current channel state measurement information. And in the embodiments of the present disclosure, the offset N slots need to be determined based on factors such as the time for comparing the channel state measurement information, the start time of the uplink symbol, and the slot alignment time. And it is also possible to appropriately expand the first period and the second period according to the stable channel quality condition of the terminal. For example, the first period and the second period are increased to 1280 time slots, etc., which can effectively reduce the power consumption of the terminal. In the embodiments of the present disclosure, when the terminal periodically reports the channel state measurement information based on the second period on the physical uplink control channel PUCCH resource, the terminal reports the channel state measurement information using format 2 of the PUCCH resource. The network-side device receiving the channel state measurement information in format 2 of the PUCCH resource is applicable to the channel state measurement information with a relatively small payload, avoiding the waste of the PUCCH resource.

[0114] In another implementation, for the case where the terminal makes an aperiodic measurement of the channel state information. The network-side device statically configures the time-frequency domain resource of the PUCCH for the terminal to report the channel state information through RRC signaling. The channel state measurement information is reported based on the first PUCCH resource. The time-domain position of the first PUCCH is: offset by N time slots relative to the time-domain resource position corresponding to the channel state information measurement, serving as the time-domain resource position for receiving the current channel state measurement information. This implementation is similar to the above implementation. To avoid wasting the PUCCH resource, the terminal reports the channel state measurement information using format 2 of the PUCCH resource. The network-side device receives the channel state measurement information based on format 2 of the PUCCH resource, and this method is applicable to the channel state measurement information with a relatively small payload.

[0115] Exemplarily, Figure 7 FIG. is a schematic diagram of the time-domain resource position offset slots of the received channel state measurement information and the channel state information measurement in a method for reporting channel state information shown according to an exemplary embodiment. As Figure 7 shown, if the value of N is 2, the time-domain resource position of the reported CSI measurement information is offset by 2 time slots from the time-domain resource position of the channel state information measurement.

[0116] Based on receiving channel state measurement information in the second period, the network-side device can receive the channel state measurement information reported by the terminal in a timely manner.

[0117] In the embodiments of the present disclosure, the offset positions of N time slot resources can be determined based on predefined information. In some embodiments, the base station can set N to a fixed value through configured signaling or communication protocols; in other embodiments, the base station can dynamically determine the offset value N based on the configured signaling. The network-side device receives the channel state measurement information at a time domain resource position that is offset by N time slots relative to the time domain resource position of the channel state information measurement based on the value of N determined according to the predefined information. In another way, the network-side device can also determine the value of N through RRC signaling. At this time, the value of N can vary flexibly. The network-side device can select a candidate offset time slot from the offset time slot set as the time domain resource position for reporting the channel state measurement information that is offset by N time slots relative to the channel state information measurement based on the processing capability of the terminal. And configure the value of N for the terminal through RRC signaling. As described above, the channel state information is measured and the channel state measurement information is received based on different time domain resources of the PUCCH resource.

[0118] Receiving the channel state measurement information based on the PUCCH resource further includes a way that the network-side device is based on the PUCCH resource obtained by the terminal requesting through the first uplink scheduling request (Scheduling Request, SR) SR1 for reporting the channel state measurement information. In some embodiments, the network-side device configures the PUCCH resource for the terminal to report the channel state measurement information. Wherein the first uplink scheduling request SR1 is dedicated to requesting the PUCCH resource for reporting the channel state measurement information.

[0119] When the network-side device receives the dedicated SR1 signaling sent by the terminal, it allocates the PUCCH resource required for the terminal to report the channel state measurement information. According to the above embodiments, it can be known that the first configuration parameter for the terminal to report the channel state information is determined by the network side. Therefore, the network-side device can determine the size of the payload of the channel state measurement information reported by the terminal at this time. When the network-side device determines that the payload of the channel state measurement information reported by the terminal is small at this time, the network-side device can instruct the terminal to use PUCCH format 2 to report the channel state measurement information. When the network-side device determines that the payload of the channel state measurement information reported by the terminal is large at this time, the network-side device can instruct the terminal to use a new PUCCH format to report the channel state measurement information. And allocate more time-frequency resources for the new PUCCH format. The network-side device instructs the terminal to use the PUCCH resource position and format through DCI instructions.

[0120] An embodiment of the present disclosure provides a method for reporting channel state information. This embodiment can be implemented independently or in combination with any other embodiment of the present disclosure. The method for reporting channel state information in the embodiment of the present disclosure includes: the terminal reports channel state measurement information through PUSCH resources.

[0121] In one implementation, for the case where there are available PUSCH resources for the terminal currently. If the terminal determines that there are available PUSCH resources currently, it determines to use the currently available PUSCH resources to report channel state measurement information. The network-side device receives the channel state measurement information based on the currently available PUSCH resources of the terminal. For the convenience of description in the present disclosure, the currently available PUSCH resources are referred to as the first PUSCH resources. Among them, the first PUSCH resources are used to transmit other uplink data simultaneously. In the embodiment of the present disclosure, to distinguish the channel state measurement information from other uplink data, the MAC CE using the first PUSCH resources carries the channel state measurement information. The MAC CE uses the reserved value 35 of the logical channel identify (LCID) of the Uplink Shared Channel (UL-SCH). In the embodiment of the present disclosure, the MAC CE for reporting the channel state measurement information is a variable byte, and the number of bytes of the MAC CE for reporting the channel state measurement information is determined based on the number of measurement items included in the reported channel state measurement information.

[0122] In another implementation, the terminal can reuse the PUSCH resources of the BSR to report channel state measurement information, and the network-side device receives the channel state measurement information based on the PUSCH resources of the BSR. Exemplarily, this implementation can be applied to the case where there are no available PUSCH resources currently and no other available uplink transmissions. For the convenience of description in the present disclosure, the PUSCH resources carrying the BSR are referred to as the second PUSCH resources. In the present disclosure, the reserved value 35 of the LCID of the UL-SCH is used for reporting the channel state measurement information. Exemplarily, Figure 8 is a schematic diagram of receiving channel state measurement information by reusing the PUSCH resources carrying the BSR in a method for reporting channel state information shown according to an exemplary embodiment. As Figure 8As shown, the terminal requests, based on a general scheduling request (SR), that the network device configure a Physical Uplink Shared Channel (PUSCH) resource for receiving channel state measurement information. After receiving the request information sent by the terminal, the network device configures a PUSCH resource for the terminal, and the network device receives the channel state measurement information based on the configured PUSCH resource for the terminal. It can be understood that since the PUSCH resource for transmitting the Buffer Status Report (BSR) allocated by the network device to the terminal is small, this embodiment is applicable to the case where the payload for carrying the channel state measurement information is small.

[0123] In another embodiment, the network device may receive the channel state measurement information based on a first PUSCH resource for transmitting other uplink data transmissions, or receive the channel state measurement information and other uplink transmission data together. Exemplarily, this embodiment may be applied to a situation where there is currently no available PUSCH resource and there are other uplink transmissions. Figure 9 is a schematic diagram of receiving channel state information measurement information using other uplink data transmission resources in a method for reporting channel state information according to an exemplary embodiment. As Figure 9 shown, at this time, the terminal requests, based on a general scheduling request (SR), to use a PUSCH resource for reporting channel state measurement information. Taking other uplink data as the BSR as an example, the network device configures a PUSCH resource for transmitting the BSR for the terminal based on the scheduling request sent by the terminal. The BSR transmitted by the terminal reports the signaling of the channel state measurement information and the overhead of other data to the network device together. The network device configures a PUSCH resource for uploading other data and channel state measurement information for the terminal based on the signaling of the channel state measurement information and the overhead of other data. The network device receives the channel state measurement information and other uplink data based on the PUSCH resource. In the embodiments of the present disclosure, reporting the channel state measurement information is carried by a MAC Control Element (MAC-CE) of the PUSCH resource, and the reserved value 35 of the Logical Channel ID (LCID) of the UL-SCH is used. This embodiment can also be used for the case where the payload of the channel state measurement information is large and there is no other uplink data to be transmitted.

[0124] In the embodiments of the present disclosure, receiving the channel state measurement information based on the PUSCH resource further includes a method. The network device receives a second uplink scheduling request (SR2) sent by the terminal. The second uplink scheduling request (SR2) is dedicated to requesting a third PUSCH resource for obtaining and reporting the channel state measurement information, and the third PUSCH resource is dedicated to transmitting the channel state measurement information. The implementation method includes that the terminal sends an SR2 request to apply for a third PUSCH resource for reporting the channel state measurement information, and the network allocates a third PUSCH resource for reporting the channel state measurement information for the terminal based on the dedicated scheduling request SR2 of the terminal. The size of the third PUSCH resource is determined based on a first configuration parameter configured by the network device for the terminal.

[0125] In the embodiments of the present disclosure, by configuring multiple ways to receive channel state measurement information, the flexibility of receiving channel state measurement information is increased. Moreover, the dedicated SR1 and SR2 involved in the present disclosure are redesigned and can be distinguished from general SR and dedicated SR1 and SR2 through different time-frequency domain resource positions / sequences. It can be understood that the redesigned dedicated SR1 and SR2 in the present disclosure will not affect other uplink scheduling requests.

[0126] The embodiments of the present disclosure propose a method for reporting channel state information. This embodiment can be implemented independently or in combination with any other embodiment of the present disclosure. The method for reporting channel state information in the embodiments of the present disclosure includes: the terminal collaboratively reports channel state measurement information through PUCCH resources and PUSCH resources.

[0127] In some embodiments, when there are available PUCCH resources, use the PUCCH resources to report channel state measurement information; when there are no available PUCCH resources, use the PUSCH resources to report channel state measurement information. As for how to report through PUCCH resources, any method in the embodiments of the present disclosure can be referred to, or any feasible method in related technologies can be adopted. Similarly, as for how to report through PUSCH resources, any method in the embodiments of the present disclosure can be referred to, or any feasible method in related technologies can be adopted.

[0128] In some embodiments, it is possible to use PUCCH resources to report channel state measurement information when there are available PUCCH resources, and use PUSCH resources to report channel state measurement information when there are no available PUCCH resources. As for how to report through PUCCH resources, any method in the embodiments of the present disclosure can be referred to, or any feasible method in related technologies can be adopted. Similarly, as for how to report through PUSCH resources, any method in the embodiments of the present disclosure can be referred to, or any feasible method in related technologies can be adopted.

[0129] Based on the same concept, the embodiments of the present disclosure further provide a communication method applied to a first type of terminal.

[0130] In some embodiments, the first type of terminal determines a first configuration parameter, where the first configuration parameter includes a threshold value of measurement information of the channel state.

Combining the units and algorithm steps of the examples disclosed in the embodiments of the present disclosure, the embodiments of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a certain function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution.

[0138] Figure 10 is a block diagram of a terminal 100 shown according to an exemplary embodiment. Referring to Figure 10 , the device includes a processing module 101 and a reporting module 102.

[0139] The processing module 101 is configured to determine a first configuration parameter, where the first configuration parameter includes a threshold value, and determine a difference between a first channel state measurement value and a second channel state measurement value, where the terminal is a first type of terminal. The reporting module 102 is configured to report measurement information based on the magnitude relationship between the threshold value and the difference; where the first type of terminal is a low-capability terminal.

Or in response to the difference between the first channel state information measurement value and the second channel state information measurement value of the channel state being equal to the threshold value, report the channel state measurement information.

[0141] In the embodiment of the present disclosure, the reporting module 102 is configured to, in response to the difference between the first channel state information measurement value and the second channel state information measurement value of the channel state being less than the threshold value of the channel state measurement information, not report the channel state measurement information.
