Description

[0001] This application is a divisional application. The application number of the original application is 202080002643.3, the application date is September 30, 2020, and the invention title is "A Channel Quality Indication (CQI) Reporting Method, Device, and Storage Medium". Technical Field

[0002] The present disclosure relates to the field of wireless communication technologies, and in particular, to a channel quality indication (CQI) reporting method, device, and storage medium. Background Art

[0003] In a wireless communication system, for scenarios such as low rate and high latency of Internet of Things (IoT) services, machine type communication (MTC) technology and narrow band Internet of Things (NB-IoT) technology have been proposed.

[0004] Due to the development of IoT services, MTC and NB-IoT technologies can no longer meet the requirements of current IoT services for rate and latency. Therefore, a new type of terminal, reduced capability (Redcap) UE, or simply referred to as NR-lite, is designed to cover the service requirements of the IoT. Due to the requirements of low cost and low complexity of the Redcap terminal, as well as the reduction of the number of antennas and bandwidth, the coverage capability of the terminal is reduced. Therefore, the measurement result of the signal to interference plus noise ratio (SINR, also known as the signal-to-noise ratio) of the Redcap terminal is lower than the range of SINR supported by the channel quality indication (CQI) parameter set. When the network receives the reported CQI, it cannot accurately determine the channel condition information, and thus cannot determine the corresponding coverage compensation strategy.

[0094] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0103] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the 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.

[0104] In a communication system, for scenarios such as low rate and high latency in the Internet of Things (IoT) services (such as meter reading, environmental monitoring, etc.), the related technologies propose two major technologies: Machine-Type Communication (MTC) and NarrowBand Internet of Things (NB-IoT). Currently, the NB-IoT technology can support a maximum rate of several hundred K, and the MTC can support a maximum rate of several M. However, with the continuous development of IoT services (such as monitoring, smart home, wearable devices, and industrial sensor detection, etc.), generally a rate of dozens to one hundred M is required, and the requirement for latency is also relatively increased. Therefore, in the communication system, the two major technologies of MTC and NB-IoT can no longer meet the requirements of current IoT services. Thus, it is proposed to design a new user equipment in the new air interface of the communication system to cover the service requirements of mid-range IoT devices with a rate requirement of dozens to one hundred M and relatively high latency. Currently, in the standardization of the 3rd Generation Partnership Project (3GPP), the user equipment that can cover the service requirements of mid-range IoT devices with a rate requirement of dozens to one hundred M and relatively high latency is called Reduced capability UE (abbreviated as Redcap terminal or NR-lite).

[0105] On the other hand, NR-lite generally needs to meet requirements such as low cost, low complexity, a certain degree of coverage enhancement, and power saving. However, the new air interface communication technology is designed for high-end terminals with high data rate and low latency, and cannot meet the above requirements of NR-lite. Therefore, it is necessary to transform the current new air interface communication technology to meet the above requirements of NR-lite. For example, according to the requirements of low cost and low complexity, the radio frequency (RF) bandwidth of the new air interface Internet of Things can be restricted (for example, restricted to 5 MHz or 10 MHz; or the size of the buffer of NR-lite can be restricted), and then the size of each received transport block can be restricted, etc. For another example, according to the requirement of power saving, the communication process can be simplified to reduce the number of times NR-lite users detect the downlink control channel, etc.

[0106] However, in a wireless communication system, after the terminal measures the channel, it needs to report the measured SINR to the network side in the form of CQI. In a wireless communication system, the terminal reports CQI based on a CQI parameter set. In other words, the terminal determines the modulation method, channel coding rate, and spectral efficiency corresponding to the CQI parameter set when the measured SINR meets the reference resources of the CSI parameter set, selects the highest CQI index among all CQI indexes that meet the block error rate (BLER) requirement, and reports the highest CQI index to the network. The network side determines the corresponding modulation method, channel coding rate, and spectral efficiency according to the CQI index. In the related art, for terminals with 64QAM, there are two CQI parameter sets that can be used, the first CQI parameter set and the second CQI parameter set. Among them, the first CQI parameter set and the second CQI parameter set correspond to different BLER requirements respectively. The first CQI parameter set is used when meeting the requirement that BLER is equal to the first threshold, and Table 1 can be referred to; the second CQI parameter set is used when meeting the requirement that BLER is equal to the second threshold, and Table 2 can be referred to. It should be understood that the spectral efficiency supported by the second CQI parameter set is lower than that supported by the first CQI parameter set.

[0107] Table 1

[0108]

[0109] Table 2

[0110]

[0111] It can be understood that each element in Table 1 and Table 2 exists independently. These elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist simultaneously as shown in the table. The value of each element is independent of the values of any other elements in Table 1 and Table 2. Therefore, those skilled in the art can understand that the value taken by each element in Table 1 and Table 2 is an independent embodiment.

[0112] However, due to the limitations of Redcap terminal capabilities, such as the reduction in the number of antennas and bandwidth, the coverage ability of Redcap terminals will also be limited. In some cases, it may cause the measured SINR of the Redcap terminal to be lower than the SINR range supported by the CQI parameter set. Compared with the first CQI parameter set, the lowest SINR supported by the first CQI parameter set is around -5 dB. When the measured SINR of the terminal is lower than -5 dB, at this time, the measured SINR result is not within the SINR range supported by the first CQI parameter set, and the CQI index reported by the terminal is 0, that is, CQI = 0. In the first CQI parameter set, the information corresponding to CQI index 0 is out of range. For Redcap terminals with only 1 antenna, the situation where the measured SINR result is out of range occurs relatively frequently. If the terminal only reports the out of range information, when the network receives the CQI reported by the terminal, it cannot accurately determine the channel quality, and thus cannot determine the corresponding coverage compensation strategy.

[0113] Therefore, the present disclosure provides a method for reporting channel quality indication (CQI), which re-determines the CQI parameter set by adjusting the first CQI parameter set, or by using the second CQI parameter set, or by adjusting the SINR range, so that when reporting the corresponding CQI information, it is no longer out of range. 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 quality indication (CQI) provided by the present disclosure can be applied to Figure 1 the communication system architecture diagram shown. As Figure 1 shown, the terminal reports CQI, and the network-side device determines the modulation mode, channel coding rate, and spectral efficiency of the terminal at this time according to the received CQI.

[0114] 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. In Figure 1It is not shown in the figure. The embodiments of the present disclosure do not limit the number of network devices and terminals included in the wireless communication system.

[0115] Furthermore, 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) network, 3G network, 4G network, or future evolved network, such as 5G network. The 5G network can also be referred to as the New Radio (NR). For the convenience of description, the wireless communication network is sometimes simply referred to as the network in the present disclosure.

[0116] 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.

[0117] 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 capabilities, a vehicle-mounted device, etc. Currently, some examples of terminals are: smartphones (Mobile Phone), pocket personal computers (PPC), palmtop 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.

[0118] In an embodiment of the present disclosure, a method for reporting channel quality indicator (CQI) is provided.

[0119] Figure 2 It is a flowchart of a method for reporting channel quality indicator (CQI) shown according to an exemplary embodiment. As Figure 2 shown, the method for reporting channel quality indicator (CQI) is used in a first type of terminal and includes the following steps.

[0120] In step S11, report the CQI according to the CQI parameter set corresponding to the first type of terminal.

[0121] In some embodiments, before executing step S11, it may also be executed: determine the CQI parameter set corresponding to the first type of terminal.

[0122] In an embodiment of the present disclosure, the first type of terminal is a reduced-capability terminal (Redcap UE). The Redcap UE may have a situation where the spectral efficiency is lower than the first threshold. Among them, the signal-to-noise ratio corresponding to the first threshold of the spectral efficiency is -5 dB. When the spectral efficiency of the first type of terminal is lower than the first threshold, determine the corresponding CQI parameter set according to the indication message sent by the network-side device. Determine the reported CQI index in the corresponding CQI parameter set according to the channel quality parameters measured by the first type of terminal and the requirement of the block error rate. In an embodiment of the present disclosure, the indication message sent by the network-side device may be determined based on predefined information, or determined based on signaling indication; among them, the signaling may be radio resource control (RRC) signaling, etc.

[0123] In the embodiments of the present disclosure, the CQI parameter set may also be referred to as a CQI table. The CQI parameter set includes at least one of the following: a CQI index, a modulation method corresponding to each CQI index, a coding rate, and a spectral efficiency. The terminal may report the CQI index based on the determined CQI parameter set, and the network-side device determines the corresponding information based on the CQI index reported by the terminal to further determine the channel condition of the terminal.

[0124] In the embodiments of the present disclosure, the CQI index may indicate different CQI indexes based on a specified number of bits. The number of bits of the specified data may be determined based on the number of CQI indexes. Exemplarily, if the CQI parameter set includes 16 CQI indexes, 4 bits may be used to indicate different CQI indexes. For example, 0000 indicates that the CQI index is 0, 0001 indicates that the CQI index is 1, and so on. Of course, these are only examples and are not limitations on the embodiments of the present disclosure.

[0125] In some embodiments of the present disclosure, a method for reporting a channel quality indicator (CQI) may determine that the CQI parameter set is a third CQI parameter set and report the CQI based on the third CQI parameter set. The third CQI parameter set is determined by adding new different spectral efficiencies based on the first CQI parameter set. This embodiment of the present disclosure may be implemented alone or in conjunction with any other embodiment of the present disclosure, and the embodiments of the present disclosure do not make any limitations thereto.

[0126] In the embodiments of the present disclosure, the lowest spectral efficiency corresponding to the third CQI parameter set is less than the first threshold. And / or, the highest spectral efficiency corresponding to the third CQI parameter set is less than the second threshold. It can be understood that the first CQI parameter set is the CQI parameter set corresponding to the second type of terminal meeting the first BLER requirement. The first BLER requirement is that the BLER of the terminal data channel is less than or equal to the first percentage threshold (for example, 10%). In the embodiments of the present disclosure, the determined third CQI parameter set is determined based on the first CQI parameter set. In other words, the third CQI parameter set determined in the embodiments of the present disclosure is obtained by adding spectral efficiencies lower than the first threshold and deleting a preset number of relatively high spectral efficiencies in the first CQI parameter set. For ease of description, in the embodiments of the present disclosure, the lowest spectral efficiency included in the first CQI parameter set is referred to as the first threshold, and the highest spectral efficiency included in the first CQI parameter set is referred to as the second threshold. In some embodiments, the number of added spectral efficiencies may be the same as the number of deleted spectral efficiencies.

[0127] In the embodiments of the present disclosure, the number of CQI indices included in the determined third CQI parameter set is the same as the number of CQI indices included in the first CQI parameter set. As described above, when determining the number of CQI indices, if a new spectral efficiency lower than the first threshold is added to the first CQI parameter set, a relatively high spectral efficiency needs to be deleted from the first CQI parameter set. Thus, a new CQI parameter set is obtained, and the new CQI parameter set is determined as the third CQI parameter set. Moreover, it is determined that at least one spectral efficiency in the third CQI parameter set is less than the first threshold. Exemplarily, the present disclosure illustrates the determination of the third CQI parameter set by taking the addition of two spectral efficiencies lower than the first threshold and the deletion of two relatively high spectral efficiencies as an example. Refer to Table 3. The CQI index includes a total of 16 different CQI indices, as well as the modulation method, channel coding rate, and spectral efficiency corresponding to each CQI index.

[0130] It can be understood that each element in Table 3 exists independently. These elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist simultaneously as shown in the table. The value of each element is independent of the values of any other elements in Table 3. Therefore, those skilled in the art can understand that the value of each element in this Table 3 is an independent embodiment.

[0131] As shown in Table 3, two spectral efficiencies lower than the first threshold are added, which correspond to CQI index 1 and CQI index 2. Among them, the first threshold is 0.1523. Therefore, n < m < 0.1523, and the channel coding rate corresponding to n is x, the channel coding rate corresponding to m is y, and the channel coding rate corresponding to 0.1523 is 78. So, y < x < 78. At the same time, the information associated with the CQI indices corresponding to the relatively high spectral efficiencies 3.9023 and 4.5234 is deleted. It can be understood that the addition of two spectral efficiencies lower than the first threshold in the present disclosure is only for easy understanding and does not specifically limit the number of spectral efficiencies lower than the first threshold added.

[0132] In an embodiment of the present disclosure, based on the number of spectral efficiencies lower than a first threshold added to a first CQI parameter set, relatively high spectral efficiencies in the first CQI parameter set are determined to be deleted, thereby determining a third CQI parameter set. If there are multiple relatively high spectral efficiencies to be deleted from the first CQI parameter set, the relatively high spectral efficiencies to be deleted may be based on the spectral efficiencies corresponding to consecutive CQI indices or non-consecutive CQI indices. And in an embodiment of the present disclosure, the determined third CQI parameter set may be configured for some Redcap UEs or all Redcap UEs. Other types of terminals may be configured to use the first CQI parameter set determined by the communication protocol.

[0133] In some embodiments of the present disclosure, a method for reporting channel quality indicator (CQI) may determine that the CQI parameter set is a second CQI parameter set, and report CQI based on the second CQI parameter set. This embodiment of the present disclosure may be implemented independently or in combination with any other embodiment of the present disclosure, and the embodiments of the present disclosure do not make any limitations in this regard.

[0134] In an embodiment of the present disclosure, the second CQI parameter set is the CQI parameter set corresponding to a second type of terminal (meeting the second BLER requirement). The second BLER requirement is that the BLER of the terminal data channel is less than or equal to a second percentage threshold (e.g., 0.00001). In an embodiment of the present disclosure, the network-side device determines, based on an indicator for indicating a Redcap UE included in an indication message, that when the BLER of the Redcap UE data channel is less than a first percentage threshold (e.g., 10%), it is determined that the second CQI parameter set can be used to report CQI; or it is determined that when the BLER of the Redcap UE data channel is equal to the first percentage threshold (e.g., 10%), it is determined that the second CQI parameter set can be used to report CQI. In other words, when the terminal type is a Redcap UE and the BLER of the Redcap UE data channel is less than or equal to the first percentage threshold (e.g., 10%), the second CQI parameter set is used. Alternatively, when the network-side device configures the second CQI parameter set for the terminal through a first indication message, that is, a terminal with the second CQI parameter set explicitly configured, it is determined that the second CQI parameter set can be used to report CQI. Among them, the first indication message is used to indicate that the terminal configures the second CQI parameter set. In an embodiment of the present disclosure, the second type of terminal may be an ordinary NR terminal, and the first type of terminal may be a Redcap UE with reduced capabilities.

[0135] In some embodiments of the present disclosure, a method for reporting channel quality indication (CQI) may determine that a CQI parameter set is a first CQI parameter set and report the CQI based on the first CQI parameter set. This embodiment of the present disclosure can be implemented alone or in conjunction with any other embodiment of the present disclosure, and the embodiments of the present disclosure do not limit this.

[0136] Figure 3 is a flowchart of a method for reporting channel quality indication (CQI) shown according to an exemplary embodiment, as Figure 3 shown, the channel quality indication (CQI) reporting method is used in a reduced-capability terminal (Redcap UE), and includes the following steps.

[0137] In step S21, a first offset value and a measured channel quality parameter are determined.

[0138] In step S22, a corrected channel quality parameter is determined according to the measured channel quality parameter and the first offset value.

[0139] In step S23, the CQI is determined and reported according to the corrected channel quality parameter and the first CQI parameter set.

[0140] In the embodiments of the present disclosure, the first offset value may be an offset value based on the channel quality parameter. By adding the first offset value to the measured channel quality parameter, the corrected channel quality parameter can be determined. The spectral efficiency corresponding to the corrected channel quality parameter is within the spectral efficiency range included in the first CQI parameter set that satisfies the first BLER requirement for the second type of terminal. Therefore, the CQI can be reported using the first CQI parameter set based on the corrected CQI. When the network-side device receives the CQI index reported based on the first CQI parameter set, the first offset value can also be determined, and the measured SINR after removing the first offset value can be further determined, so as to determine the current channel condition information of the terminal channel. In the embodiments of the present disclosure, the first deviation value may be determined based on predefined information or communication protocols.

[0141] Exemplarily, the SINR in the channel quality parameter measured by the first type of terminal is -5 dB, and the first deviation value is 5 dB. The spectral efficiency corresponding to -5 dB is not within the spectral efficiency range included in the first CQI parameter set. At this time, by adding the first deviation value of 5 dB to the measured SINR of -5 dB, the corrected SINR is obtained as 0. And the spectral efficiency corresponding to the corrected SINR belongs to the spectral efficiency range included in the first CQI parameter set. Therefore, the terminal can determine the corrected CQI based on the corrected SINR and report the CQI based on the corrected CQI and the first CQI parameter set determined by the communication protocol.

[0142] In some embodiments of the present disclosure, a method for reporting channel quality indication (CQI) may further determine that the CQI parameter set is the first CQI parameter set and report the CQI based on the first CQI parameter set. This embodiment of the present disclosure may be implemented alone or in combination with any other embodiment of the present disclosure, and the embodiments of the present disclosure do not limit this.

[0143] Figure 4 is a flowchart of a method for reporting channel quality indication (CQI) shown according to an exemplary embodiment, as Figure 4 shown, the method for reporting channel quality indication (CQI) is used in a reduced-capability terminal (Redcap UE) and includes the following steps.

[0144] In step S31, measurement resources are determined.

[0145] Among them, the measurement resources include multiple repeated transmissions.

[0146] In step S32, measurement and merging are performed based on the measurement resources including multiple repeated transmissions, and the channel quality parameters of the merged measurement are determined.

[0147] In step S33, based on the first CQI parameter set and / or the second CQI parameter set, and the channel quality parameters of the merged measurement, the CQI is determined and reported.

[0148] In the embodiments of the present disclosure, when determining the block error rate (BLER) of the data channel, it is measured based on the reference resources of the channel state information (CSI). Therefore, the measurement resources can be determined based on the reference resources of the CSI, and at least the number of repeated transmissions of the reference resources of the CSI is included in the measurement resources. At this time, the measurement can be re-performed based on the reference resources for multiple repeated transmissions, and the BLERs of the data channels of each measurement are merged, and then the channel quality parameters of the merged measurement are determined. According to the channel quality parameters of the merged measurement, among the first CQI parameter set corresponding to the first type of terminal satisfying the first block error rate (BLER) requirement and / or the second CQI parameter set corresponding to the second type of terminal satisfying the second block error rate (BLER) requirement, the reported CQI index is determined.

[0149] In the embodiments of the present disclosure, multiple repeated transmissions can configure the repetition number of the CSI reference resource in the time domain. In one way, the network-side device can determine the repeated transmission of the CSI reference resource in the time domain for the Redcap UE through Radio Resource Control (RRC) signaling. Alternatively, in another embodiment, the network-side device can configure the repeated transmission of the CSI reference resource in the time domain for the Redcap UE based on the maximum number of transmissions of the downlink physical channel. For example, the maximum repetition number of the Physical Downlink Control Channel (PDCCH), or the maximum repetition number of the Physical Downlink Shared Channel (PDSCH).

[0150] It should be understood that in the embodiments of the present disclosure, the first BLER requirement is that when using the modulation mode and coding rate in the CQI parameter set, the BLER of the data channel is less than the first percentage threshold (e.g., 10%), or the first BLER requirement is that when using the modulation mode and coding rate in the CQI parameter set, the BLER of the data channel is equal to the first percentage threshold. The second BLER requirement is that when using the modulation mode and coding rate in the CQI parameter set, the BLER of the data channel is less than the second percentage threshold (e.g., 0.0001); or the second BLER requirement is that when using the modulation mode and coding rate in the CQI parameter set, the BLER of the data channel is equal to the second percentage threshold. In the embodiments of the present disclosure, the channel quality parameter of the first type of terminal is less than that of the second type of terminal.
